Various PMSMs use skew to suppress torque ripple, but 3-D finite element analysis (3-D-FEA) is required in order to accurately determine an appropriate structure for skewed PMSMs, resulting in a long analysis time. Therefore, this article constructs a hybrid analysis method that combines numerical calculations and minimal 3-D-FEA. The aim of this method is to be practical and easy to use, even for novice designers, and to accurately and quickly design skewed PMSMs. In this article, the effectiveness of the proposed method is clarified through several case studies, and then, a skewed PMSM designed using the proposed method is verified experimentally. It is also revealed that suppression of voltage harmonics contributes to improving the performance of PMSMs in experiments. en-copyright= kn-copyright= en-aut-name=TsunataRen en-aut-sei=Tsunata en-aut-mei=Ren kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IchimuraYu en-aut-sei=Ichimura en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakemotoMasatsugu en-aut-sei=Takemoto en-aut-mei=Masatsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ImaiJun en-aut-sei=Imai en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Design method kn-keyword=Design method en-keyword=efficiency kn-keyword=efficiency en-keyword=field weakening control kn-keyword=field weakening control en-keyword=interior permanent magnet synchronous motor (IPMSM) kn-keyword=interior permanent magnet synchronous motor (IPMSM) en-keyword=PMSMs kn-keyword=PMSMs en-keyword=skew kn-keyword=skew en-keyword=torque ripple kn-keyword=torque ripple en-keyword=voltage harmonics kn-keyword=voltage harmonics END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue= article-no= start-page=e72549 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250624 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Optimization of Preemptive Therapy for Cytomegalovirus Infections With Valganciclovir Based on Therapeutic Drug Monitoring: Protocol for a Phase II, Single-Center, Single-Arm Trial en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Valganciclovir (VGCV) is the first-line drug for preemptive therapy of cytomegalovirus (CMV) infections. However, even when administered at the dose specified in the package insert, there is significant interindividual variability in the plasma concentrations of ganciclovir (GCV). In addition, correlations have been reported between the area under the concentration?time curve and therapeutic efficacy or adverse events. Therefore, therapeutic drug monitoring (TDM) can be used to improve the efficacy and safety of preemptive VGCV therapy.
Objective: This study aims to evaluate whether the dosage adjustment of VGCV based on TDM in patients undergoing preemptive therapy for CMV infections is associated with the successful completion rate of treatment without severe hematological adverse effects.
Methods: This phase II, single-center, single-arm trial aims to enroll 40 patients admitted at the Department of Rheumatology and Clinical Immunology, Kobe University Hospital, who will receive oral VGCV as preemptive therapy for CMV infections. Participants will begin treatment with VGCV at the dose recommended in the package insert, with subsequent dose adjustments based on weekly TDM results. The primary end point will be the proportion of patients who achieve CMV antigenemia negativity within 3 weeks without severe hematological adverse events. The secondary end points will include weekly changes in CMV antigen levels, total VGCV dose, and duration of preemptive therapy. For safety evaluation, the occurrence, type, and severity of VGCV-related adverse events will be analyzed. Additionally, this study will explore the correlations between the efficacy and safety of preemptive therapy and the pharmacokinetic parameters of GCV, CMV-polymerase chain reaction values, and nudix hydrolase 15 (NUDT15) genetic polymorphisms. The correlation between GCV plasma concentrations obtained from regular venous blood and blood concentrations will be examined using dried blood spots.
Results: This study began with patient recruitment in September 2024, with 5 participants enrolled as of June 16, 2025. The target enrollment is 40 participants, and the anticipated study completion is set for July 2027.
Conclusions: This is the first study to investigate the impact of TDM intervention in patients receiving VGCV as preemptive therapy. The findings are postulated to provide valuable evidence regarding the utility of TDM in patients receiving VGCV as preemptive therapy.

In this study, we developed a plant-insertable sucrose sensor capable of real-time sucrose concentration monitoring and demonstrated its application as a useful tool for plant research by monitoring the sugar-translocating path from leaves to the lower portion of plants through the stem in living plants. The biosensor consists of a bilirubin oxidase-based biocathode and a needle-type bioanode integrating glucose oxidase, invertase, and mutarotase, with the two electrodes separated by an agarose gel for ionic connection. The sensor exhibits a sensitivity of 6.22 μA mM?1 cm?2, a limit of detection of 100 μM, a detection range up to 60 mM, and a response time of 90 s at 100 μM sucrose. Additionally, the sensor retained 86 % of its initial signal after 72 h of continuous measurement. Day-night monitoring from the biosensor inserted in strawberry guava (Psidium cattleianum) showed higher sucrose transport activity at night, following well the redistribution of photosynthetically produced sugars. In addition, by monitoring the forced translocation of sucrose dissolved in the stable isotopically labeled water, we demonstrated that a young seedling of Japanese cedar known as Sugi (Cryptomeria japonica) can absorb and transport both water and sucrose through light-dependently opened stomata, which is the recently revealed path for liquid uptake by higher plants. These findings highlight the potential of our sensor for studying dynamic plant processes and its applicability in real-time monitoring of sugar transport under diverse environmental conditions. en-copyright= kn-copyright= en-aut-name=WuShiqi en-aut-sei=Wu en-aut-mei=Shiqi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakagawaWakutaka en-aut-sei=Nakagawa en-aut-mei=Wakutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MoriYuki en-aut-sei=Mori en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AzhariSaman en-aut-sei=Azhari en-aut-mei=Saman kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=M?hesG?bor en-aut-sei=M?hes en-aut-mei=G?bor kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NishinaYuta en-aut-sei=Nishina en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KawanoTomonori en-aut-sei=Kawano en-aut-mei=Tomonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MiyakeTakeo en-aut-sei=Miyake en-aut-mei=Takeo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Graduate School of Information, Production and Systems, Waseda University kn-affil= affil-num=2 en-affil=Graduate School of Information, Production and Systems, Waseda University kn-affil= affil-num=3 en-affil=Faculty and Graduate School of Environmental Engineering, The University of Kitakyushu kn-affil= affil-num=4 en-affil=Graduate School of Information, Production and Systems, Waseda University kn-affil= affil-num=5 en-affil=Graduate School of Information, Production and Systems, Waseda University kn-affil= affil-num=6 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=7 en-affil=Faculty and Graduate School of Environmental Engineering, The University of Kitakyushu kn-affil= affil-num=8 en-affil=Graduate School of Information, Production and Systems, Waseda University kn-affil= en-keyword=Flexible wearable sensor kn-keyword=Flexible wearable sensor en-keyword=Plant monitoring kn-keyword=Plant monitoring en-keyword=Carbon fiber kn-keyword=Carbon fiber en-keyword=Multi-enzyme system kn-keyword=Multi-enzyme system END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=12 article-no= start-page=1399 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250611 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association Between Chewing Status and Steatotic Liver Disease in Japanese People Aged ?50 Years: A Cohort Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: In this longitudinal study, the relationship between chewing status and steatotic liver disease (SLD) was examined in 3775 people aged ?50 years who underwent medical checkups at Junpukai Health Maintenance Center in Okayama, Japan. Methods: Participants without SLD at the time of a baseline survey in 2018 were followed until 2022. Chewing status was assessed by a self-administered questionnaire. The presence or absence of SLD was ascertained from the medical records of Junpukai Health Maintenance Center. Results: A total of 541 participants (14%) were diagnosed as having a poor chewing status at baseline. Furthermore, 318 (8%) participants were newly diagnosed with SLD at follow-up. In multivariate logistic regression analyses, the presence or absence of SLD was found to be associated with the following characteristics at baseline: sex (male: odds ratio [ORs] = 1.806; 95% confidence interval [CIs]: 1.399?2.351), age (ORs = 0.969; 95% CIs: 0.948?0.991), body mass index (?25.0 kg/m2; ORs = 1.934; 95% CIs: 1.467?2.549), diastolic blood pressure (ORs = 1.017; 95% CIs: 1.002?1.032), and chewing status (poor: ORs = 1.472; 95% CIs: 1.087?1.994). Conclusions: The results indicate that a poor chewing status was associated with SLD development after 4 years. Aggressively recommending dental visits to participants with poor chewing status may not only improve their ability to chew well but may also reduce the incidence of SLD. en-copyright= kn-copyright= en-aut-name=IwaiKomei en-aut-sei=Iwai en-aut-mei=Komei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=EkuniDaisuke en-aut-sei=Ekuni en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AzumaTetsuji en-aut-sei=Azuma en-aut-mei=Tetsuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YonenagaTakatoshi en-aut-sei=Yonenaga en-aut-mei=Takatoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TabataKoichiro en-aut-sei=Tabata en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ToyamaNaoki en-aut-sei=Toyama en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KataokaKota en-aut-sei=Kataoka en-aut-mei=Kota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MaruyamaTakayuki en-aut-sei=Maruyama en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TomofujiTakaaki en-aut-sei=Tomofuji en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Community Oral Health, School of Dentistry, Asahi University kn-affil= affil-num=2 en-affil=Department of Preventive Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Community Oral Health, School of Dentistry, Asahi University kn-affil= affil-num=4 en-affil=Department of Community Oral Health, School of Dentistry, Asahi University kn-affil= affil-num=5 en-affil=Department of Community Oral Health, School of Dentistry, Asahi University kn-affil= affil-num=6 en-affil=Department of Preventive Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Preventive Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Preventive Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Community Oral Health, School of Dentistry, Asahi University kn-affil= en-keyword=oral health kn-keyword=oral health en-keyword=liver diseases kn-keyword=liver diseases en-keyword=longitudinal studies kn-keyword=longitudinal studies en-keyword=mastication kn-keyword=mastication en-keyword=physical examination kn-keyword=physical examination en-keyword=surveys and questionnaires kn-keyword=surveys and questionnaires END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=2 article-no= start-page=156 end-page=167 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250602 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Metaverse Support Groups for LGBTQ+ Youth: An Observational Study on Safety, Self-Expression, and Early Intervention en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study explored whether metaverse-based support groups could address social isolation and suicide risks among LGBTQ+ youths by providing enhanced anonymity, avatar-based self-expression, and improved accessibility. Over one year, 53 individuals aged 14?23 participated in regular online sessions facilitated via the "cluster" metaverse platform by a non-profit LGBTQ+ organization. Each 90-minute session included voice and text-based interactions within a specially designed single-floor virtual space featuring conversation areas and a designated "safe area" for emotional regulation. Post-session questionnaires (5-point Likert scales) captured demographics, avatar preferences, self-confidence, and perceived safety, self-expression, and accessibility; responses were analyzed with Pearson's chi-squared test and Mann?Whitney U tests (α=0.05). Results indicated that 79.2% of participants selected avatars aligned with their gender identity, reporting high satisfaction (mean = 4.10/5) and minimal discomfort (mean = 1.79/5). Social confidence was significantly higher in the metaverse compared with real-world settings (p<0.001), particularly among those with lower real-world confidence, who exhibited an average gain of 2.08 points. Approximately half of all first-time participants were aged 16 years or younger, which suggested the platform’s value for early intervention. Additionally, the metaverse environment was rated significantly higher in safety/privacy (3.94/5), self-expression (4.02/5), and accessibility (4.21/5) compared with the real-world baseline, and 73.6% reported they felt more accepted virtually. However, some participants who had high confidence offline experienced mild adaptation challenges (mean decrease of 0.58 points), which highlighted that metaverse-based support may be more effective as a complement to in-person services rather than a replacement. Overall, these findings demonstrate that metaverse-based support groups can reduce psychological barriers for LGBTQ+ youth by facilitating safe and affirming virtual environments. The metaverse may help alleviate emotional distress and prevent further severe outcomes, such as suicidal ideation by providing early intervention, especially for adolescents unable to access conventional in-person services. Further research should examine its integration with existing clinical, community, and educational resources to ensure comprehensive, long-term support. en-copyright= kn-copyright= en-aut-name=HaseiJoe en-aut-sei=Hasei en-aut-mei=Joe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumotoYosuke en-aut-sei=Matsumoto en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KawaiHiroki en-aut-sei=Kawai en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OkahisaYuko en-aut-sei=Okahisa en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakakiManabu en-aut-sei=Takaki en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Okayama University kn-affil= affil-num=2 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Science of Functional Recovery and Reconstruction, Graduate School of Medicine, Dentistry and Pharmaceu-tical Sciences, Okayama University kn-affil= en-keyword=LGBTQ+ Youth kn-keyword=LGBTQ+ Youth en-keyword=Social Isolation kn-keyword=Social Isolation en-keyword=Suicide Prevention kn-keyword=Suicide Prevention en-keyword=Avatar-Based Interventions kn-keyword=Avatar-Based Interventions END start-ver=1.4 cd-journal=joma no-vol=410 cd-vols= no-issue=1 article-no= start-page=20 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=An effective surgical educational system in the era of robotic surgery: “Double-Surgeon Technique” in robotic gastrectomy for minimally invasive surgery en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose Gastric cancer (GC) remains a major malignancy. Robotic gastrectomy (RG) has gained popularity due to various advantages. Despite those advantages, many hospitals lack the necessary equipment for RG and are still performing laparoscopic gastrectomy (LG) due to its established minimal invasiveness and safety.
Methods This study assessed the effectiveness of the “Double-Surgeon Technique” (DST) for improving surgical education and proficiency with LG. The DST involves both a console-side surgeon and a patient-side surgeon working actively in RG, enhancing the skill acquisition needed for LG and potentially reducing surgical time. Assessment of this method was performed by surgical time, and cases were divided into three groups: first half (Phase 1: P1) and second half (P2) before the introduction of DST, and after the introduction of DST (P3).
Results Two surgical trainees were trained using the DST. The learning curve in both reached a plateau in P2, but descended again in P3. For one trainee, surgical time for P3 was significantly reduced compared to P1 (p?=?0.001) and P2 (p?=?0.0027) despite the intervals between laparoscopic distal gastrectomy as the main surgeon in P3 being significantly longer than in P2 (p?=?0.0094). Other surgical results in both trainees did not differ significantly. Further, no difference in induction phase results of RG were evident between surgeons and trainees with or without DST experience.
Conclusion Surgical education using the DST could be effective in the current context of the need for RG and LG. en-copyright= kn-copyright= en-aut-name=KakiuchiYoshihiko en-aut-sei=Kakiuchi en-aut-mei=Yoshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KurodaShinji en-aut-sei=Kuroda en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YoshidaYusuke en-aut-sei=Yoshida en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KanayaNobuhiko en-aut-sei=Kanaya en-aut-mei=Nobuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KashimaHajime en-aut-sei=Kashima en-aut-mei=Hajime kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KikuchiSatoru en-aut-sei=Kikuchi en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KagawaShunsuke en-aut-sei=Kagawa en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Surgical education kn-keyword=Surgical education en-keyword=Gastrectomy kn-keyword=Gastrectomy en-keyword=Minimally invasive surgery kn-keyword=Minimally invasive surgery en-keyword=Robotic gastrectomy kn-keyword=Robotic gastrectomy en-keyword=Endoscopic surgical skill qualification system qualification kn-keyword=Endoscopic surgical skill qualification system qualification END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=1561628 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250321 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Histidine-rich glycoprotein inhibits TNF-α?induced tube formation in human vascular endothelial cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Tumor necrosis factor-α (TNF-α)-induced angiogenesis plays a critical role in tumor progression and metastasis, making it an important therapeutic target in cancer treatment. Suppressing angiogenesis can effectively limit tumor growth and metastasis. However, despite advancements in understanding angiogenic pathways, effective strategies to inhibit TNF-α-mediated angiogenesis remain limited.
Methods: This study investigates the antiangiogenic effects of histidine-rich glycoprotein (HRG), a multifunctional plasma protein with potent antiangiogenic properties, on TNF-α-stimulated human endothelial cells (EA.hy926). Tube formation assays were performed to assess angiogenesis, and gene/protein expression analyses were conducted to evaluate HRG’s effects on integrins αV and β8. The role of nuclear factor erythroid 2-related factor 2 (NRF2) in HRG-mediated antiangiogenic activity was also examined through nuclear translocation assays and NRF2 activation studies.
Results: At physiological concentrations, HRG effectively suppressed TNF-α-induced tube formation in vitro and downregulated TNF-α-induced expression of integrins αV and β8 at both the mRNA and protein levels. HRG treatment promoted NRF2 nuclear translocation in a time-dependent manner. Furthermore, activation of NRF2 significantly reduced TNF-α-induced tube formation and integrin expression, suggesting that NRF2 plays a key role in HRG-mediated antiangiogenic effects.
Discussion and Conclusion: Our findings indicate that HRG suppresses TNF-α-induced angiogenesis by promoting NRF2 nuclear translocation and transcriptional activation, which in turn inhibits integrin αV and β8 expression. Given the essential role of angiogenesis in tumor progression, HRG’s ability to regulate this process presents a promising therapeutic strategy for cancer treatment. en-copyright= kn-copyright= en-aut-name=HatipogluOmer Faruk en-aut-sei=Hatipoglu en-aut-mei=Omer Faruk kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishinakaTakashi en-aut-sei=Nishinaka en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YaykasliKursat Oguz en-aut-sei=Yaykasli en-aut-mei=Kursat Oguz kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoriShuji en-aut-sei=Mori en-aut-mei=Shuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WatanabeMasahiro en-aut-sei=Watanabe en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ToyomuraTakao en-aut-sei=Toyomura en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NishiboriMasahiro en-aut-sei=Nishibori en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HirohataSatoshi en-aut-sei=Hirohata en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=WakeHidenori en-aut-sei=Wake en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TakahashiHideo en-aut-sei=Takahashi en-aut-mei=Hideo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Pharmacology, Kindai University Faculty of Medicine kn-affil= affil-num=2 en-affil=Department of Pharmacology, Kindai University Faculty of Medicine kn-affil= affil-num=3 en-affil=Department of Internal Medicine 3?Rheumatology and Immunology, Friedrich-Alexander-University Erlangen-N?rnberg (FAU) and Universit?tsklinikum Erlangen kn-affil= affil-num=4 en-affil=Department of Pharmacology, School of Pharmacy, Shujitsu University kn-affil= affil-num=5 en-affil=Department of Pharmacology, School of Pharmacy, Shujitsu University kn-affil= affil-num=6 en-affil=Department of Pharmacology, School of Pharmacy, Shujitsu University kn-affil= affil-num=7 en-affil=Department of Translational Research and Dug Development, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Medical Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Pharmacology, Kindai University Faculty of Medicine kn-affil= affil-num=10 en-affil=Department of Pharmacology, Kindai University Faculty of Medicine kn-affil= en-keyword=histidine-rich glycoprotein kn-keyword=histidine-rich glycoprotein en-keyword=tumor necrosis factor-α kn-keyword=tumor necrosis factor-α en-keyword=integrin kn-keyword=integrin en-keyword=tube formation kn-keyword=tube formation en-keyword=angiogenesis kn-keyword=angiogenesis en-keyword=factor erythroid 2-related factor 2 kn-keyword=factor erythroid 2-related factor 2 END start-ver=1.4 cd-journal=joma no-vol=390 cd-vols= no-issue= article-no= start-page=116594 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202508 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Extension-type flexible pneumatic actuator with a large extension force using a cross-link mechanism based on pantographs en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this study, we propose an extension-type flexible pneumatic actuator (EFPA) with a high extension force and no buckling. In a previous study, soft actuators that extended in the axial direction by applying a supply pressure were unable to generate the extension’s pushing force because the actuators buckled owing to their high flexibility. To generate a pushing force, the circumferential stiffness of an extension-type flexible soft actuator must be reinforced. Therefore, a cross-linked EFPA (CL-EFPA) was developed, inspired by a pantograph that restrains the EFPA three-dimensionally using the proposed link mechanism. The proposed CL-EFPA consists of three EFPAs and a cross-linking mechanism for integrating each EFPA circumference. The pushing force of the CL-EFPA is approximately 3.0 times compared with that generated by the previous EFPA with plates to restrain its plane. To perform various bending motions, attitude control was performed using an analytical model and a system that included valves, sensors, and controllers. en-copyright= kn-copyright= en-aut-name=ShimookaSo en-aut-sei=Shimooka en-aut-mei=So kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TadachiKazuma en-aut-sei=Tadachi en-aut-mei=Kazuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KamegawaTetsushi en-aut-sei=Kamegawa en-aut-mei=Tetsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Mechanical and Systems Engineering Program, School of Engineering, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Soft robot kn-keyword=Soft robot en-keyword=Extension soft actuator kn-keyword=Extension soft actuator en-keyword=Link mechanism kn-keyword=Link mechanism en-keyword=Pantograph kn-keyword=Pantograph en-keyword=Attitude control kn-keyword=Attitude control END start-ver=1.4 cd-journal=joma no-vol=43 cd-vols= no-issue=2 article-no= start-page=282 end-page=289 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240917 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluation of a novel central venous access port for direct catheter insertion without a peel-away sheath en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose This study retrospectively evaluated the feasibility and safety of implanting a newly developed central venous access port (CV-port) that allows catheter insertion into a vein without the use of a peel-away sheath, with a focus on its potential to minimize risks associated with conventional implantation methods.
Materials and methods All procedures were performed using a new device (P-U CelSite Port? MS; Toray Medical, Tokyo, Japan) under ultrasound guidance. The primary endpoint was the implantation success rate. The secondary endpoints were the safety and risk factors for infection in the early postprocedural period ( Results We assessed 523 CV-port implantations performed in a cumulative total of 523 patients (240 men and 283 women; mean age, 61.6?±?13.1 years; range, 18?85 years). All implantations were successfully performed using an inner guide tube and over-the-wire technique through 522 internal jugular veins and one subclavian vein. The mean procedural time was 33.2?±?10.9 min (range 15?112 min). Air embolism, rupture/perforation of the superior vena cava, or hemothorax did not occur during catheter insertion. Eleven (2.1%) intraprocedural complications occurred, including Grade I arrhythmia (n?=?8) and subcutaneous bleeding (n?=?1), Grade II arrhythmia (n?=?1), and Grade IIIa pneumothorax (n?=?1). Furthermore, 496 patients were followed up for???30 days. Six early postprocedural complications were encountered (1.1%), including Grade IIIa infection (n?=?4), catheter occlusion (n?=?1), and skin necrosis due to subcutaneous leakage of trabectedin (n?=?1). These six CV-ports were withdrawn, and no significant risk factors for infection in the early postprocedural period were identified.
Conclusion The implantation of this CV-port device demonstrated comparable success and complication rates to conventional devices, with the added potential benefit of eliminating complications associated with the use of a peel-away sheath. en-copyright= kn-copyright= en-aut-name=IguchiToshihiro en-aut-sei=Iguchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawabataTakahiro en-aut-sei=Kawabata en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsuiYusuke en-aut-sei=Matsui en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TomitaKoji en-aut-sei=Tomita en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UkaMayu en-aut-sei=Uka en-aut-mei=Mayu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UmakoshiNoriyuki en-aut-sei=Umakoshi en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkamotoSoichiro en-aut-sei=Okamoto en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MunetomoKazuaki en-aut-sei=Munetomo en-aut-mei=Kazuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HirakiTakao en-aut-sei=Hiraki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Central venous catheters kn-keyword=Central venous catheters en-keyword=Vascular access device kn-keyword=Vascular access device en-keyword=Treatment outcome kn-keyword=Treatment outcome en-keyword=Safety kn-keyword=Safety END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250704 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Primary tumour resection plus systemic therapy versus systemic therapy alone in metastatic breast cancer (JCOG1017, PRIM-BC): a randomised clinical trial en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Several prospective studies have evaluated the benefit of primary tumour resection (PTR) in de novo Stage IV breast cancer (BC) patients, but it remains controversial. We aimed to investigate whether PTR improves the survival of de novo stage IV BC patients.
Methods: De novo stage IV BC patients were enrolled in the first registration and received systemic therapies according to clinical subtypes. Patients without progression after primary systemic therapy for 3 months were randomly assigned 1:1 to systemic therapy alone (arm A) or PTR plus systemic therapy (arm B). The primary endpoint was overall survival (OS), and the secondary endpoints included local relapse-free survival (LRFS).
Results: Five hundred seventy patients were enrolled between May 5, 2011, and May 31, 2018. Of these, 407 were randomised to arm A (N?=?205) or arm B (N?=?202). The median follow-up time of all randomised patients was 60 months. The difference in OS was not statistically significant (HR 0.86 90% CI 0.69?1.07, one-sided p?=?0.13). Median OS was 69 months (arm A) and 75 months (arm B). In the subgroup analysis, PTR was associated with improved OS in pre-menopausal patients, or those with single-organ metastasis. LRFS in arm B was significantly longer than that in arm A (median LRFS 20 vs. 63 months: HR 0.42, 95% CI 0.33?0.53, p? Conclusions: PTR did not prolong OS. However, it improved local control and might benefit a subset of patients, such as those with premenopausal status or with single-organ metastasis. It also improved local relapse-free survival (LRFS), which is a clinically meaningful outcome in trials of systemic therapy.

As the number of new technologies and peripheral devices increases year by year, there is a need for time-efficient and accurate commissioning of radiation therapy equipment. Couch modeling is one type of commissioning, and there are no recommended values for CT due to differences in equipment calibration between facilities. This study evaluated the optimal electron density (ED) for the couch using discretized gantry angles.
Results All discrete-angle groups showed a high correlation between the surface ED and dose difference between the actual and planned doses (|r|>?0.9). AcurosXB did not demonstrate a significant correlation between dose differences and each energy. For a small number of discretized gantry groups, the optimal couch modeling results revealed several combinations of surface and interior ED with the same score. Upon adding all couch thickness scores, all energy scores, and both algorithm scores, the optimal surface and interior EDs with the highest score across all couch thicknesses were 0.4 and 0.07, respectively.
Conclusions The optimal couch surface ED dose difference trend was identified, and the effectiveness indicated using the dose difference score from discrete-angle couch modeling. Using this method, couch modeling can be evaluated in a highly precise and quick manner, which helps in the commissioning of complicated linear accelerator and radiological treatment plans. en-copyright= kn-copyright= en-aut-name=TomimotoSyouta en-aut-sei=Tomimoto en-aut-mei=Syouta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SaekiYusuke en-aut-sei=Saeki en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MotodaOkihiro en-aut-sei=Motoda en-aut-mei=Okihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaMasato en-aut-sei=Tanaka en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TsumotoSyouki en-aut-sei=Tsumoto en-aut-mei=Syouki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NishikawaHana en-aut-sei=Nishikawa en-aut-mei=Hana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MiyashimaYuki en-aut-sei=Miyashima en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HiguchiMakiko en-aut-sei=Higuchi en-aut-mei=Makiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TaniTadashi en-aut-sei=Tani en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KatsuiKuniaki en-aut-sei=Katsui en-aut-mei=Kuniaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TanabeYoshinori en-aut-sei=Tanabe en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Radiological Technology, Faculty of Medicine, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Radiological Technology, Kawasaki Medical School Hospital kn-affil= affil-num=3 en-affil=Department of Radiological Technology, Kawasaki Medical School Hospital kn-affil= affil-num=4 en-affil=Department of Radiological Technology, Kawasaki Medical School Hospital kn-affil= affil-num=5 en-affil=Department of Radiological Technology, Faculty of Medicine, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Radiological Technology, Faculty of Medicine, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Radiological Technology, Kawasaki Medical School Hospital kn-affil= affil-num=8 en-affil=Department of Radiological Technology, Kawasaki Medical School Hospital kn-affil= affil-num=9 en-affil=Department of Radiological Technology, Kawasaki Medical School Hospital kn-affil= affil-num=10 en-affil=Department of Radiology, Kawasaki Medical School kn-affil= affil-num=11 en-affil=Department of Radiological Technology, Faculty of Medicine, Graduate School of Health Sciences, Okayama University kn-affil= en-keyword=Couch modeling kn-keyword=Couch modeling en-keyword=Commissioning kn-keyword=Commissioning en-keyword=Attenuation of couch kn-keyword=Attenuation of couch en-keyword=Linear accelerator kn-keyword=Linear accelerator en-keyword=Radiotherapy planning system kn-keyword=Radiotherapy planning system END start-ver=1.4 cd-journal=joma no-vol=156 cd-vols= no-issue=2 article-no= start-page=151 end-page=159.e1 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202502 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The greater palatine nerve and artery both supply the maxillary teeth en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background. It is generally accepted that the greater palatine nerve and artery supply the palatal mucosa, gingiva, and glands, but not the bone or tooth adjacent to those tissues. When the bony palate is observed closely, multiple small foramina are seen on the palatal surface of the alveolar process. The authors hypothesized that the greater palatine nerve and artery might supply the maxillary teeth via the foramina on the palatal surface of the alveolar process and the superior alveolar nerve and artery. The authors aimed to investigate the palatal innervation and blood supply of the maxillary teeth.
Methods. Eight cadaveric maxillae containing most teeth or alveolar sockets were selected. The mean age at the time of death was 82.4 years. The samples were examined with colored water injection, latex injection, microcomputed tomography with contrast dye, gross anatomic dissection, and histologic observation.
Results. Through both injection studies and microcomputed tomographic analysis, the authors found that the small foramina on and around the greater palatine groove connected to the alveolar process and tooth sockets. The small foramina in the greater palatine and incisive canal also continued inside the alveolar process and the tooth sockets.
Conclusions. The alveolar branches of the greater palatine nerve and artery as well as the nasopalatine nerve and sphenopalatine artery supply maxillary teeth, alveolar bone, and periodontal tissue via the palatal alveolar foramina with superior alveolar nerves and arteries.
Practical Implications. This knowledge is essential for dentists when administering local anesthetic to the maxillary teeth and performing an osteotomy.

The Asia-Pacific body mass index (BMI) classification sets lower obesity cutoffs than the conventional BMI classification for all races, generally reflecting the lower BMIs in Asians. This longitudinal study evaluated the association between BMI, as classified by the Asia-Pacific BMI system, and CKD development in non-diabetic Asian adults. Methods: A population-based longitudinal study (1998?2023) was conducted in non-diabetic Japanese adults (hemoglobin A1c < 6.5%) in Zentsuji City (Kagawa Prefecture, Japan). The generalized gamma model was used to assess the relationship between time-varying BMI categories and CKD development, stratified by sex. CKD was defined as an estimated glomerular filtration rate of <60 mL/min/1.73 m2. BMI was calculated as weight (kg) divided by the square of height (m2) and categorized per the Asia-Pacific classification as overweight (23.0?24.9 kg/m2), obesity class I (25.0?29.9 kg/m2), and obesity class II (?30.0 kg/m2). Results: CKD developed in 34.2% of 3098 men and 34.8% of 4391 women. The mean follow-up times were 7.41 years for men and 8.25 years for women. During follow-up, the BMI distributions for men were 5.0% underweight, 43.3% normal weight, 25.6% overweight, 24.1% obesity class I, and 2.0% obesity class II; those for women were 7.7%, 50.5%, 20.5%, 18.3%, and 2.9%, respectively. Compared with normal weight, obesity class I was associated with a 6% (95% confidence interval [CI]: 2?10%) shorter time to CKD onset in men and 5% (95% CI: 2?7%) in women. In both sexes, obesity class II showed shorter survival times than normal weight by point estimates, although all 95% CIs crossed the null value. Conclusions: Obesity, as classified by the Asia-Pacific BMI system, shortened the time to CKD onset in non-diabetic Asians. The conventional BMI cutoff for obesity (?30.0 kg/m2) may be too high to identify CKD risk in this population. The findings of this study may be useful for public health professionals in designing interventions to prevent CKD. en-copyright= kn-copyright= en-aut-name=OkawaYukari en-aut-sei=Okawa en-aut-mei=Yukari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsudaToshihide en-aut-sei=Tsuda en-aut-mei=Toshihide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Public Health and Welfare, Zentsuji City Hall kn-affil= affil-num=2 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=body mass index kn-keyword=body mass index en-keyword=chronic kidney disease kn-keyword=chronic kidney disease en-keyword=East Asian kn-keyword=East Asian en-keyword=longitudinal studies kn-keyword=longitudinal studies en-keyword=risk factors kn-keyword=risk factors END start-ver=1.4 cd-journal=joma no-vol=52 cd-vols= no-issue=8 article-no= start-page=e18026 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202508 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Commissioning of respiratory‐gated 4D dynamic dose calculations for various gating widths without spot timestamp in proton pencil beam scanning en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Proton pencil beam scanning (PBS) is susceptible to dose degradation because of interplay effects on moving targets. For cases of unacceptable motion, respiratory-gated (RG) irradiation is an effective alternative to free breathing (FB) irradiation. However, the introduction of RG irradiation with larger gate widths (GW) is hindered by interplay effects, which are analogous to those observed with FB irradiation. Accurate estimation of interplay effects can be performed by recording spot timestamps. However, our machine lacks this feature, making it imperative to find an alternative approach. Thus, we developed an RG 4-dimensional dynamic dose (RG-4DDD) system without spot timestamps.
Purpose: This study aimed to investigate the accuracy of calculated doses from the RG-4DDD system for PBS plans with varying breathing curves, amplitudes, and periods for 10%?50% GW.
Methods: RG-4DDDs were reconstructed using in-house developed software that assigned timestamps to individual spots, integrated start times for spills with breathing curves, and utilized deformable registrations for dose accumulation. Three cubic verification plans were created using a heterogeneous phantom. Additionally, typical liver and lung cases were employed for patient plan validation. Single- and multi-field-optimized (SFO and IMPT) plans (ten beams in total) were created for the liver and lung cases in a homogeneous phantom. Lateral profile measurements were obtained under both motion and no-motion conditions using a 2D ionization chamber array (2D-array) and EBT3 Gafchromic films on the CIRS dynamic platform. Breathing curves from the cubic plans were used to assess nine patterns of sine curves, with amplitudes of 5.0?10.0 mm (10.0?20.0 mm target motions) and periods of 3?6 sec. Patient field verifications were conducted using a representative patient curve with an average amplitude of 6.4 mm and period of 3.2 sec. Additional simulations were performed assuming a ± 10% change in assigned timestamps for the dose rate (DR), spot spill (0.08-s), and gate time delay (0.1-s) to evaluate the effect of parameter selection on our 4DDD models. The 4DDDs were compared with measured values using the 2D gamma index and absolute doses over that required for dosing 95% of the target.
Results: The 2D-array measurements showed that average gamma scores for the reference (no motion) and 4DDD plans for all GWs were at least 99.9 ± 0.2% and 98.2 ± 2.4% at 3%/3 mm, respectively. The gamma scores of the 4DDDs in film measurements exceeded 95.4% and 92.9% at 2%/2 mm for the cubic and patient plans, respectively. The 4DDD calculations were acceptable under DR changes of ±10% and both spill and gate time delays of ±0.18 sec. For the 4DDD plan using all GWs for all measurement points, the absolute point differences for all validation plans were within ±5.0% for 99.1% of the points.
Conclusions: The RG-4DDD calculations (less than 50% GW) of the heterogeneous and actual patient plans showed good agreement with measurements for various breathing curves in the amplitudes and periods described above. The proposed system allows us to evaluate actual RG irradiation without requiring the ability to record spot timestamps. en-copyright= kn-copyright= en-aut-name=TominagaYuki en-aut-sei=Tominaga en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WakisakaYushi en-aut-sei=Wakisaka en-aut-mei=Yushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KatoTakahiro en-aut-sei=Kato en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IchiharaMasaya en-aut-sei=Ichihara en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YasuiKeisuke en-aut-sei=Yasui en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SasakiMotoharu en-aut-sei=Sasaki en-aut-mei=Motoharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OitaMasataka en-aut-sei=Oita en-aut-mei=Masataka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NishioTeiji en-aut-sei=Nishio en-aut-mei=Teiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Radiotherapy, Medical Co.

We aimed to develop a novel counting-loss correction procedure in which biological objects having effective atomic numbers (Zeff values) of 6.5?13.0 are measured with polychromatic X-rays. To correct for counting loss, such a procedure must theoretically estimate the count value of an ideal X-ray spectrum without counting loss. In this study, we estimated the ideal X-ray spectrum by focusing on the following two points: (1) the X-ray attenuation in an object (Zeff values of 6.5?13.0) and (2) the detector response. Virtual materials having intermediate atomic numbers between 6.5 and 13.0 were generated by using a mixture of polymethylmethacrylate (PMMA, Zeff = 6.5) and aluminum (Al, Zeff = 13.0). We then constructed an algorithm that can perform the counting-loss correction based on the object’s true Zeff value. To demonstrate the applicability of our procedure, we analyzed investigational objects consisting of PMMA and Al using a prototype ERPCD system. A fresh fish sample was also analyzed. The Zeff values agree with the theoretical values within an accuracy of Zeff ±1. In conclusion, we have developed a highly accurate procedure for correcting counting losses for the quantitative X-ray imaging of biological objects. en-copyright= kn-copyright= en-aut-name=KimotoNatsumi en-aut-sei=Kimoto en-aut-mei=Natsumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishigamiRina en-aut-sei=Nishigami en-aut-mei=Rina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KobayashiDaiki en-aut-sei=Kobayashi en-aut-mei=Daiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MaedaTatsuya en-aut-sei=Maeda en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AsaharaTakashi en-aut-sei=Asahara en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=GotoSota en-aut-sei=Goto en-aut-mei=Sota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KanazawaYuki en-aut-sei=Kanazawa en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KatsumataAkitoshi en-aut-sei=Katsumata en-aut-mei=Akitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YamamotoShuichiro en-aut-sei=Yamamoto en-aut-mei=Shuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HayashiHiroaki en-aut-sei=Hayashi en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Radiological Science, Faculty of Health Sciences, Junshin Gakuen University kn-affil= affil-num=2 en-affil=Graduate School of Medical Sciences, Kanazawa University kn-affil= affil-num=3 en-affil=Graduate School of Medical Sciences, Kanazawa University kn-affil= affil-num=4 en-affil=Graduate School of Medical Sciences, Kanazawa University kn-affil= affil-num=5 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=6 en-affil=Faculty of Health Science, Kobe Tokiwa University kn-affil= affil-num=7 en-affil=Faculty of Life Science, Kumamoto University kn-affil= affil-num=8 en-affil=Oral Radiology and Artificial Intelligence, Asahi University kn-affil= affil-num=9 en-affil=JOB CORPORATION kn-affil= affil-num=10 en-affil=College of Transdisciplinary Sciences for Innovation, Kanazawa University kn-affil= en-keyword=Photon-counting detector kn-keyword=Photon-counting detector en-keyword=Pulse pile-up kn-keyword=Pulse pile-up en-keyword=Dead time kn-keyword=Dead time en-keyword=Counting-loss correction kn-keyword=Counting-loss correction en-keyword=Charge-sharing effect kn-keyword=Charge-sharing effect en-keyword=Effective atomic number kn-keyword=Effective atomic number END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=77 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240410 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Impact of amyloid and tau positivity on longitudinal brain atrophy in cognitively normal individuals en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Individuals on the preclinical Alzheimer's continuum, particularly those with both amyloid and tau positivity (A?+?T?+), display a rapid cognitive decline and elevated disease progression risk. However, limited studies exist on brain atrophy trajectories within this continuum over extended periods.
Methods This study involved 367 ADNI participants grouped based on combinations of amyloid and tau statuses determined through cerebrospinal fluid tests. Using longitudinal MRI scans, brain atrophy was determined according to the whole brain, lateral ventricle, and hippocampal volumes and cortical thickness in AD-signature regions. Cognitive performance was evaluated with the Preclinical Alzheimer's Cognitive Composite (PACC). A generalized linear mixed-effects model was used to examine group?×?time interactions for these measures. In addition, progression risks to mild cognitive impairment (MCI) or dementia were compared among the groups using Cox proportional hazards models.
Results A total of 367 participants (48 A?+?T?+?, 86 A?+?T???, 63 A???T?+?, and 170 A???T???; mean age 73.8 years, mean follow-up 5.1 years, and 47.4% men) were included. For the lateral ventricle and PACC score, the A?+?T???and A?+?T?+?groups demonstrated statistically significantly greater volume expansion and cognitive decline over time than the A???T???group (lateral ventricle: β?=?0.757 cm3/year [95% confidence interval 0.463 to 1.050], P? Conclusions In cognitively normal individuals, A?+?T?+?compounds brain atrophy and cognitive deterioration, amplifying the likelihood of disease progression. Therapeutic interventions targeting A?+?T?+?individuals could be pivotal in curbing brain atrophy, cognitive decline, and disease progression. en-copyright= kn-copyright= en-aut-name=FujishimaMotonobu en-aut-sei=Fujishima en-aut-mei=Motonobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawasakiYohei en-aut-sei=Kawasaki en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsudaHiroshi en-aut-sei=Matsuda en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Radiology, Kumagaya General Hospital kn-affil= affil-num=2 en-affil=Department of Biostatistics, Graduate School of Medicine, Saitama Medical University kn-affil= affil-num=3 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Biofunctional Imaging, Fukushima Medical University kn-affil= en-keyword=Preclinical kn-keyword=Preclinical en-keyword=Alzheimer’s disease kn-keyword=Alzheimer’s disease en-keyword=Longitudinal MRI kn-keyword=Longitudinal MRI en-keyword=Tau kn-keyword=Tau en-keyword=Amyloid-β kn-keyword=Amyloid-β END start-ver=1.4 cd-journal=joma no-vol=207 cd-vols= no-issue= article-no= start-page=108683 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202509 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Intracranial activity of sotorasib vs docetaxel in pretreated KRAS G12C-mutated advanced non-small cell lung cancer from a global, phase 3, randomized controlled trial en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: To assess the efficacy and safety of sotorasib in patients with brain metastases using data from the phase 3 CodeBreaK 200 study, which evaluated sotorasib in adults with pretreated advanced or metastatic KRAS G12C-mutated non-small cell lung cancer (NSCLC).
Materials and methods: Patients with KRAS G12C-mutated NSCLC who progressed after platinum-based chemotherapy and checkpoint inhibitor therapy were randomized 1:1 to sotorasib or docetaxel. An exploratory post-hoc analysis evaluated central nervous system (CNS) progression-free survival (PFS) and time to CNS progression in patients with treated and stable brain metastases at baseline. Measures were assessed by blinded independent central review per study-modified Response Assessment in Neuro-Oncology Brain Metastases (RANO-BM) criteria.
Results: Of the patients randomly assigned to receive sotorasib (n=171) or docetaxel (n=174), baseline CNS metastases were present in 40 (23%) and 29 (17%) patients, respectively. With a median follow-up of 20.0 months for this patient subgroup, median CNS PFS was longer with sotorasib compared with docetaxel (9.6 vs 4.5 months; hazard ratio, 0.43 [95% CI, 0.20?0.92]; P=0.02). Among patients with baseline treated CNS lesions of ?10 mm, the percentage of patients who achieved CNS tumor shrinkage of ?30% was two-fold higher with sotorasib than docetaxel (33.3% vs 15.4%). Treatment-related adverse events among patients with CNS lesions at baseline were consistent with those of the overall study population.
Conclusions: These results suggest intracranial activity with sotorasib complements the overall PFS benefit observed with sotorasib vs docetaxel, with safety outcomes similar to those in the general CodeBreaK 200 population.

The timing of SBCE is thought to affect its diagnostic yield; however, the optimal timing remains unknown.
Methods This retrospective study analyzed 131 patients with overt gastrointestinal bleeding managed with SBCE at our institution between May 2015 and December 2022. Patients were categorized into four groups based on the interval between their last bleeding episode and SBCE: 1?7, 8?14, 15?28, and ??29 days.
Results Positive findings were observed in approximately 50% of the cases across all intervals, with no statistically significant differences in the detection rates. Vascular lesions were detected primarily within 1?14 days, whereas inflammatory lesions, tumors, and diverticula were identified across all intervals. Notably, 25% of the patients with negative SBCE findings were later diagnosed with sources of non-small bowel bleeding, highlighting the value of follow-up endoscopic evaluations.
Conclusions Our findings suggest that SBCE can be effective regardless of the time after a bleeding event, contrary to previous recommendations emphasizing its early use. Clinicians should consider performing SBCE whenever feasible to improve the diagnostic outcomes for gastrointestinal bleeding, irrespective of the elapsed time since the last episode. en-copyright= kn-copyright= en-aut-name=KametakaDaisuke en-aut-sei=Kametaka en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=InokuchiToshihiro en-aut-sei=Inokuchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KawanoSeiji en-aut-sei=Kawano en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HiraokaSakiko en-aut-sei=Hiraoka en-aut-mei=Sakiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Division of Endoscopy, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Diagnostic yield kn-keyword=Diagnostic yield en-keyword=Obscure Gastrointestinal bleeding kn-keyword=Obscure Gastrointestinal bleeding en-keyword=Retrospective study kn-keyword=Retrospective study en-keyword=Small-bowel capsule endoscopy kn-keyword=Small-bowel capsule endoscopy en-keyword=Timing of endoscopy kn-keyword=Timing of endoscopy en-keyword=Vascular lesions kn-keyword=Vascular lesions END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250116 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Factors affecting 1-year persistence with vedolizumab for ulcerative colitis: a multicenter, retrospective real-world study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Aims The objectives of this real-world study were to determine 1-year persistence with vedolizumab in patients with ulcerative colitis and to evaluate factors contributing to loss of response.
Methods In this multicenter, retrospective, observational chart review, patients with moderately to severely active ulcerative colitis who received ? 1 dose of vedolizumab in clinical practice at 16 tertiary hospitals in Japan (from December 2018 through February 2020) were enrolled.
Results Persistence with vedolizumab was 64.5% (n = 370); the median follow-up time was 53.2 weeks. Discontinuation due to loss of response among initial clinical remitters was reported in 12.5% (35/281) of patients. Multivariate analysis showed that concomitant use of tacrolimus (odds ratio [OR], 2.76; 95% confidence interval [CI], 1.00?7.62; P= 0.050) and shorter disease duration (OR for median duration ? 7.8 years vs. < 7.8 years, 0.33; 95% CI, 0.13?0.82; P= 0.017) were associated with discontinuation due to loss of response. Loss of response was not associated with prior use of anti-tumor necrosis factor alpha therapy, age at the time of treatment, disease severity, or concomitant corticosteroids or immunomodulators. Of the 25 patients with disease duration < 1 year, 32.0% discontinued due to loss of response.
Conclusions Persistence with vedolizumab was consistent with previous reports. Use of tacrolimus and shorter disease duration were the main predictors of decreased persistence. en-copyright= kn-copyright= en-aut-name=KobayashiTaku en-aut-sei=Kobayashi en-aut-mei=Taku

medial meniscus posterior root tears (MMPRTs) have not been compared. This study compared the characteristics and clinical outcomes of patients undergoing UKA with and without MMPRTs.
Materials and methods This study analyzed 68 patients. The presence or absence of MMPRTs was evaluated using preoperative magnetic resonance imaging. Patient characteristics, clinical scores before surgery and at the final evaluation, and imaging findings were compared between patients with and without MMPRTs. Multiple regression analysis was conducted on postoperative visual analog scale (VAS)-pain scores.
Results MMPRTs were present in 64.7% (44/68) of patients. Patients with MMPRTs were significantly younger (67.8?±?8.2 vs. 75.0?±?7.1 years, p? Conclusions Patients undergoing UKA with MMPRTs were younger with less radiographic osteoarthritic changes compared to those without MMPRTs, and their postoperative VAS-pain scores were significantly superior. The duration from the development of symptoms to the time of surgery significantly influenced postoperative pain in patients undergoing UKA. en-copyright= kn-copyright= en-aut-name=KawadaKoki en-aut-sei=Kawada en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YokoyamaYusuke en-aut-sei=Yokoyama en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkazakiYuki en-aut-sei=Okazaki en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TamuraMasanori en-aut-sei=Tamura en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FurumatsuTakayuki en-aut-sei=Furumatsu en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Unicompartmental knee arthroplasty kn-keyword=Unicompartmental knee arthroplasty en-keyword=Meniscus kn-keyword=Meniscus en-keyword=Posterior root tear kn-keyword=Posterior root tear en-keyword=Subchondral insufficiency fracture kn-keyword=Subchondral insufficiency fracture en-keyword=Osteoarthritis kn-keyword=Osteoarthritis END start-ver=1.4 cd-journal=joma no-vol=35 cd-vols= no-issue=1 article-no= start-page=40 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association between lower limb muscle strength and musculoskeletal ambulation disability symptom complex in patients with medial meniscus posterior root tears en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose In this study, we aimed to evaluate the changes in and the relationship between lower limb muscle strength and physical function before and after medial meniscus posterior root (MMPR) repair.
Methods Thirty-three patients who underwent MMPR repair were evaluated. Pain was evaluated with the numerical rating scale (NRS), and knee flexor/extensor muscle strength was assessed using a handheld dynamometer. Physical function was evaluated using a timed up and go (TUG) test. The NRS, knee flexor/extensor muscle strength, and TUG were compared preoperatively and 1 year postoperatively using the Wilcoxon signed-rank test. The correlation of patient characteristics, NRS score, knee flexor/extensor muscle strength, and preoperative TUG with the postoperative TUG was analyzed using Spearman’s correlation coefficient.
Results NRS (3.5?±?2.1 to 0.1?±?0.5 points), knee flexor strength (111.9?±?50.2 to 146.7?±?51.5 Nm), knee extensor strength (181.9?±?92.8 to 256.9?±?107.1 Nm), and TUG (12.3?±?5.7 to 9.2?±?2.2 s) all improved significantly from preoperatively to 1 year postoperatively (p? Conclusion In patients undergoing MMPR repair, surgery and rehabilitation significantly improve lower limb muscle strength and physical function. There was a significant correlation between lower limb muscle strength and TUG, and further strengthening of the lower limb muscles from the preoperative level is desirable to improve patients’ physical function further.

Examination revealed anterior uveitis with hypopyon and a visual acuity of 20/2,000 in the right eye, with no abnormalities in the left. Computed tomography revealed enlargement of the right maxillary sinus and internal fluid accumulation, suggesting a postoperative maxillary cyst (POMC).

A total of 561 employed individuals aged 20-64 years were analyzed. Work productivity was assessed using the Work Productivity and Activity Impairment-General Health questionnaire which evaluates absenteeism, presenteeism, and overall work productivity loss. The questionnaire responses demonstrated that the cancer survivors within 1 year of diagnosis had significantly higher absenteeism compared to the non-cancer workers (p=0.048). Although presenteeism and overall work productivity loss were also higher in the non-cancer-survivor group, the differences were not significant. Cancer survivors within 1 year of diagnosis exhibited higher absenteeism, but their work productivity appeared to recover to levels comparable to those of the non-cancer workers over time. These findings may contribute to workplace policies supporting cancer survivors’ return to work. en-copyright= kn-copyright= en-aut-name=KamanoMika en-aut-sei=Kamano en-aut-mei=Mika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KandaKanae en-aut-sei=Kanda en-aut-mei=Kanae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NgatuNlandu Roger en-aut-sei=Ngatu en-aut-mei=Nlandu Roger kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MurakamiAkitsu en-aut-sei=Murakami en-aut-mei=Akitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamadoriYusuke en-aut-sei=Yamadori en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HiraoTomohiro en-aut-sei=Hirao en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Public Health, Faculty of Medicine, Kagawa University kn-affil= affil-num=2 en-affil=Department of Public Health, Faculty of Medicine, Kagawa University kn-affil= affil-num=3 en-affil=Department of Public Health, Faculty of Medicine, Kagawa University kn-affil= affil-num=4 en-affil=Cancer Center, Kagawa University Hospital kn-affil= affil-num=5 en-affil=Department of Anesthesiology, Faculty of Medicine, Kagawa University kn-affil= affil-num=6 en-affil=Department of Public Health, Faculty of Medicine, Kagawa University kn-affil= en-keyword=cancer survivor kn-keyword=cancer survivor en-keyword=work productivity kn-keyword=work productivity en-keyword=absenteeism kn-keyword=absenteeism en-keyword=presenteeism kn-keyword=presenteeism END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=4 article-no= start-page=231 end-page=242 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202508 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Bloodstream Infections Caused by Gram-Negative Bacteria in Geriatric Patients: Epidemiology, Antimicrobial Resistance and The Factors Affecting Mortality en-subtitle= kn-subtitle= en-abstract= kn-abstract=Bloodstream infections (BSIs) are an important cause of morbidity and mortality in geriatric patients. We retrospectively analyzed the cases of geriatric patients who developed BSIs due to gram-negative bacteria in order to evaluate the epidemiology, antimicrobial resistance, and the factors affecting mortality. The cases of 110 patients aged ? 65 years admitted to our hospital between January 1, 2017, and December 31, 2022 were assessed; 70 (63.6%) of the BSIs were healthcare-associated BSIs. The urinary system was the most common detectable source of infection at 43.6%. The most frequently isolated bacteria were Escherichia coli, Pseudomonas aeruginosa, and Klebsiella pneumoniae, in that order. Carbapenem resistance was detected in 17 patients (15.5%), and extended-spectrum beta-lactamase (ESBL) production from Enterobacterales family members was detected in 37 (51.4%) patients. Multivariate analysis revealed that (i) the probability of mortality in the patients with total bilirubin was increased by approx. sixfold and (ii) the likelihood of mortality for those with a Pitt bacteremia score (PBS) ? 4 points was approx. 17 times higher. PBS and simplified qPitt scores can help predict mortality and manage geriatric patients. There is a significant increase in mortality among patients with procalcitonin (PCT) levels at ? 2 nm/ml. en-copyright= kn-copyright= en-aut-name=KardanM Enes en-aut-sei=Kardan en-aut-mei=M Enes kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ErdemIlknur en-aut-sei=Erdem en-aut-mei=Ilknur kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YildizEmre en-aut-sei=Yildiz en-aut-mei=Emre kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KirazNuri en-aut-sei=Kiraz en-aut-mei=Nuri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=?elikkolAliye en-aut-sei=?elikkol en-aut-mei=Aliye kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Infectious Diseases, Faculty of Medicine, Namik Kemal University kn-affil= affil-num=2 en-affil=Department of Infectious Diseases, Faculty of Medicine, Namik Kemal University kn-affil= affil-num=3 en-affil=Department of Infectious Diseases, Faculty of Medicine, Namik Kemal University kn-affil= affil-num=4 en-affil=Department of Medical Microbiology, Faculty of Medicine, Namik Kemal University kn-affil= affil-num=5 en-affil=Department of Biochemistry, Faculty of Medicine, Namik Kemal University kn-affil= en-keyword=geriatrics kn-keyword=geriatrics en-keyword=gram-negative bacteria kn-keyword=gram-negative bacteria en-keyword=epidemiology kn-keyword=epidemiology en-keyword=antimicrobial resistance kn-keyword=antimicrobial resistance en-keyword=mortality kn-keyword=mortality END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=4 article-no= start-page=221 end-page=229 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202508 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Organ Donation after Extracorporeal Cardiopulmonary Resuscitation: Clinical and Ethical Perspectives en-subtitle= kn-subtitle= en-abstract= kn-abstract=Extracorporeal cardiopulmonary resuscitation (ECPR) has evolved into a life-saving therapy for select cardiac arrest patients, yet a growing body of evidence suggests it also holds promise as a bridge to organ donation in non-survivors. This review explores the clinical outcomes, ethical complexities, and evolving policies surrounding organ donation after ECPR. We summarize recent international and Japanese data demonstrating favorable graft function from ECPR donors, with the exception of lung transplantation. The ethical challenges ? particularly those involving brain death determination on extracorporeal membrane oxygenation and adherence to the dead donor rule ? are discussed in the context of Japan’s recent regulatory reforms. Additionally, we highlight the importance of structured end-of-life communication through multidisciplinary team meetings in facilitating ethically sound transitions from rescue efforts to donation pathways. Moving forward, improvements in donor management, standardized legal frameworks, and public and professional education are essential to optimizing the life-saving and life-giving potential of ECPR. en-copyright= kn-copyright= en-aut-name=YumotoTetsuya en-aut-sei=Yumoto en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NaitoHiromichi en-aut-sei=Naito en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HongoTakashi en-aut-sei=Hongo en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ObaraTakafumi en-aut-sei=Obara en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KosakiYoshinori en-aut-sei=Kosaki en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AgetaKohei en-aut-sei=Ageta en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NojimaTsuyoshi en-aut-sei=Nojima en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TsukaharaKohei en-aut-sei=Tsukahara en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakaoAtsunori en-aut-sei=Nakao en-aut-mei=Atsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=brain death kn-keyword=brain death en-keyword=end-of-life care kn-keyword=end-of-life care en-keyword=ethical dilemmas kn-keyword=ethical dilemmas en-keyword=extracorporeal cardiopulmonary resuscitation kn-keyword=extracorporeal cardiopulmonary resuscitation END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250613 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Distinct age-related effects of homologous recombination deficiency on genomic profiling and treatment efficacy in gastric cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background The incidence of gastric cancer among younger patients is increasing globally, with growing attention being paid to the role of homologous recombination deficiency (HRD). However, the effect of HRD on treatment outcomes and prognosis in this population remains unclear.
Methods We analyzed clinical and genomic data from the Center for Cancer Genomics and Advanced Therapeutics database. Younger patients (??39 years, n?=?140) were compared with older patients (??65 years, n?=?1118) diagnosed with gastric cancer. This study focused on mutations in homologous recombination repair (HRR) genes and their association with tumor mutation burden (TMB), microsatellite instability (MSI), and treatment outcomes.
Results In older patients, HRD was associated with higher TMB and microsatellite instability-high (MSI-H) status, whereas no such correlations were observed in younger patients. Notably, MSI-H status was not observed in the younger group. Younger patients with HRD had a significantly shorter time to treatment failure (TTF) and overall survival (OS) than those without HRD. Conversely, in older patients, there was no significant difference in TTF or OS based on HRD status.
Conclusion HRR gene mutations influence genomic profiling, TMB, and MSI differently depending on the age of gastric cancer onset, suggesting potential effects on treatment efficacy and prognosis. en-copyright= kn-copyright= en-aut-name=MakiYoshie en-aut-sei=Maki en-aut-mei=Yoshie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KonoYoshiyasu en-aut-sei=Kono en-aut-mei=Yoshiyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OzatoToshiki en-aut-sei=Ozato en-aut-mei=Toshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamamotoHideki en-aut-sei=Yamamoto en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HirasawaAkira en-aut-sei=Hirasawa en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=EnnishiDaisuke en-aut-sei=Ennishi en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TomidaShuta en-aut-sei=Tomida en-aut-mei=Shuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HamadaKenta en-aut-sei=Hamada en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KawanoSeiji en-aut-sei=Kawano en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Faculty of Medicine, Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Medicine, Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Medicine, Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Clinical Genomic Medicine, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Clinical Genomic Medicine, Okayama University Hospital kn-affil= affil-num=6 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=7 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=8 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=9 en-affil=Faculty of Medicine, Department of Practical Gastrointestinal Endoscopy, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=11 en-affil=Faculty of Medicine, Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=12 en-affil=Faculty of Medicine, Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Homologous recombination repair gene kn-keyword=Homologous recombination repair gene en-keyword=Early-onset gastric cancer kn-keyword=Early-onset gastric cancer en-keyword=Comprehensive genomic profiling kn-keyword=Comprehensive genomic profiling END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=6 article-no= start-page=e00110-25 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250519 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Mycobacterium tuberculosis bacillus induces pyroptosis in human lung fibroblasts en-subtitle= kn-subtitle= en-abstract= kn-abstract=We previously reported that live, but not dead, virulent Mycobacterium tuberculosis (Mtb) H37Rv bacilli induce cell death in human lung fibroblast cell lines, MRC-5, MRC-9, and TIG-1. Here, using two distinct Mtb strains from two different lineages (HN878 lineage 2 and H37Rv lineage 4), we confirmed cell death at day 2 after infection with a device that measures cell growth/cytotoxicity in real time (Maestro-Z [AXION]). Mtb bacilli uptake by the fibroblast was confirmed with a transmission electron microscope on day 2. Expressions of inflammatory cytokines and interleukin (IL)?1β, IL-6, and IL-8 were observed when exposed to live, but not dead bacteria. The cell death of fibroblasts induced by both Mtb strains tested was prevented by caspase-1/4 and NLRP3 inflammasome inhibitors, but not by caspase-3 and caspase-9 inhibitors. Therefore, we classified the fibroblast cell death by Mtb infection as pyroptosis. To investigate the biological and pathological relevance of fibroblast cell death by Mtb infection, we performed dual RNA-Seq analysis on Mtb within fibroblasts and Mtb-infected fibroblasts at day 2. In Mtb bacilli tcrR, secE2, ahpD, and mazF8 genes were highly induced during infection. These genes play roles in survival in a hypoxic environment, production of a calcium-binding protein-inducing cytokine, and regulation of transcription in a toxin-antitoxin system. The gene expressions of IL-1β, IL-6, and IL-8, caspase-4, and NLRP3, but not of caspase-3 and caspase-9, were augmented in Mtb bacilli-infected fibroblasts. Taken together, our study suggests that Mtb bacilli attempt to survive in lung fibroblasts and that pyroptosis of the host fibroblasts activates the immune system against the infection. en-copyright= kn-copyright= en-aut-name=TakiiTakemasa en-aut-sei=Takii en-aut-mei=Takemasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamadaHiroyuki en-aut-sei=Yamada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MotozonoChihiro en-aut-sei=Motozono en-aut-mei=Chihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamasakiSho en-aut-sei=Yamasaki en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TorrellesJordi B. en-aut-sei=Torrelles en-aut-mei=Jordi B. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TurnerJoanne en-aut-sei=Turner en-aut-mei=Joanne kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KimishimaAoi en-aut-sei=Kimishima en-aut-mei=Aoi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AsamiYukihiro en-aut-sei=Asami en-aut-mei=Yukihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OharaNaoya en-aut-sei=Ohara en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HidaShigeaki en-aut-sei=Hida en-aut-mei=Shigeaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=HayashiHidetoshi en-aut-sei=Hayashi en-aut-mei=Hidetoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=OnozakiKikuo en-aut-sei=Onozaki en-aut-mei=Kikuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Mycobacterium Reference and Research, the Research Institute of Tuberculosis, Japan Anti-Tuberculosis Association kn-affil= affil-num=2 en-affil=Department of Mycobacterium Reference and Research, the Research Institute of Tuberculosis, Japan Anti-Tuberculosis Association kn-affil= affil-num=3 en-affil=Department of Molecular Immunology, Research Institute for Microbial Diseases, The University of Osaka kn-affil= affil-num=4 en-affil=Department of Molecular Immunology, Research Institute for Microbial Diseases, The University of Osaka kn-affil= affil-num=5 en-affil=Texas Biomedical Research Institute and International Center for the Advancement of Research & Education (I?CARE) kn-affil= affil-num=6 en-affil=Texas Biomedical Research Institute and International Center for the Advancement of Research & Education (I?CARE) kn-affil= affil-num=7 en-affil=Laboratory of Applied Microbial Chemistry, ?mura Satoshi Memorial Institute, Kitasato University kn-affil= affil-num=8 en-affil=Laboratory of Applied Microbial Chemistry, ?mura Satoshi Memorial Institute, Kitasato University kn-affil= affil-num=9 en-affil=Department of Oral Microbiology, Graduate School of Medicine, Density and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Hygienic Chemistry, Graduate School of Pharmaceutical Sciences, Nagoya City University kn-affil= affil-num=11 en-affil=Department of Cell Signaling, Graduate School of Pharmaceutical Sciences, Nagoya City University kn-affil= affil-num=12 en-affil=Department of Hygienic Chemistry, Graduate School of Pharmaceutical Sciences, Nagoya City University kn-affil= en-keyword=Mycobacterium tuberculosis kn-keyword=Mycobacterium tuberculosis en-keyword=pyroptosis kn-keyword=pyroptosis en-keyword=caspase kn-keyword=caspase en-keyword=RNA-Seq kn-keyword=RNA-Seq en-keyword=cytokine kn-keyword=cytokine en-keyword=fibroblasts kn-keyword=fibroblasts END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=10 article-no= start-page=3332 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250510 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Experience of High Tibial Osteotomy for Patients with Rheumatoid Arthritis Treated with Recent Medication: A Case Series en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: High tibial osteotomy (HTO) was generally not indicated in patients with rheumatoid arthritis (RA) because synovial inflammation may exacerbate joint damage postoperatively. Recently, joint destruction in RA has dramatically changed with the introduction of methotrexate (MTX) and biological disease-modifying antirheumatic drugs (bDMARDs). This study aimed to investigate the clinical outcomes of HTO for patients with RA treated with recent medication. Methods: In this study, patients with RA who underwent HTO between 2016 and 2020 were retrospectively reviewed. Patients whose follow-up period was <2 years and those whose onset of RA occurred after HTO were excluded. Clinical outcomes were investigated using the Japanese orthopedic Association (JOA) and visual analog scale (VAS) scores. Results: Seven patients (two males and five females, mean age 72.0 ± 6.2 years, mean body mass index 24.0 ± 2.9 kg/m2) were included in this study. The mean follow-up period was 62.1 ± 21.4 months. Open-wedge and hybrid closed-wedge HTO were performed in two and five cases, respectively. MTX was used for all cases. The bDMARDs were used in six cases (golimumab and tocilizumab in four and two cases, respectively). JOA scores significantly improved from 63.6 ± 10.7 preoperatively to 90.7 ± 5.3 postoperatively (p = 0.0167 Wilcoxon rank test). VAS scores significantly decreased from 48.6 ± 12.2 preoperatively to 11.4 ± 6.9 postoperatively (p = 0.017 Wilcoxon rank test). None of the patients underwent total knee arthroplasty. Conclusions: This study showed seven RA patients who underwent HTO treated with recent medication. The prognosis of RA, including joint destruction, has dramatically improved with induction of MTX and bDMARDs. HTO may be one of effective joint preservation surgeries even for patients with RA. To achieve the favorable outcomes, surgeons should pay attention to timing and indication of surgery. en-copyright= kn-copyright= en-aut-name=TakaharaYasuhiro en-aut-sei=Takahara en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakashimaHirotaka en-aut-sei=Nakashima en-aut-mei=Hirotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishidaKeiichiro en-aut-sei=Nishida en-aut-mei=Keiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UchidaYoichiro en-aut-sei=Uchida en-aut-mei=Yoichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatoHisayoshi en-aut-sei=Kato en-aut-mei=Hisayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ItaniSatoru en-aut-sei=Itani en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IwasakiYuichi en-aut-sei=Iwasaki en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Orthopedic Surgery, Nippon Kokan Fukuyama Hospital kn-affil= affil-num=2 en-affil=Department of Orthopedic Surgery, Nippon Kokan Fukuyama Hospital kn-affil= affil-num=3 en-affil=Department of Orthopedic Surgery, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Orthopedic Surgery, Nippon Kokan Fukuyama Hospital kn-affil= affil-num=5 en-affil=Department of Orthopedic Surgery, Nippon Kokan Fukuyama Hospital kn-affil= affil-num=6 en-affil=Department of Orthopedic Surgery, Nippon Kokan Fukuyama Hospital kn-affil= affil-num=7 en-affil=Department of Orthopedic Surgery, Nippon Kokan Fukuyama Hospital kn-affil= en-keyword=high tibial osteotomy kn-keyword=high tibial osteotomy en-keyword=rheumatoid arthritis kn-keyword=rheumatoid arthritis en-keyword=methotrexate kn-keyword=methotrexate en-keyword=biologic diseasemodifying antirheumatic drugs kn-keyword=biologic diseasemodifying antirheumatic drugs en-keyword=knee surgery kn-keyword=knee surgery en-keyword=joint preservation kn-keyword=joint preservation END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=kwaf146 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250711 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Immortal time bias from selection: a principal stratification perspective en-subtitle= kn-subtitle= en-abstract= kn-abstract=Immortal time bias due to post-treatment definition of eligibility criteria can affect experimental and observational studies, and yet, in contrast to the extensive literature on the classical form of immortal time bias, it has seldom been the focus of methodological discussions. Here, we propose an account of eligibility-related immortal time bias that uses the principal stratification framework to explain the noncomparability of treatment arms (or exposure groups) conditional on selection. In particular, we show that the statistical estimand that conditions on observed eligibility after time zero of follow-up can be interpreted using partially overlapping principal strata. Furthermore, we show that, under this perspective, as the timing of eligibility approaches time zero of follow-up, the probabilities of the outcome for eligible individuals monotonically approach the corresponding unconditional (in absence of selection) expected potential outcomes under different treatment levels. Our study provides a potential outcomes-based explanation of eligibility-related immortal time bias, and indicates that, in addition to the target trial emulation framework, principal effects might, for some studies, be useful causal estimands. en-copyright= kn-copyright= en-aut-name=Gon?alvesBronner P en-aut-sei=Gon?alves en-aut-mei=Bronner P kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SuzukiEtsuji en-aut-sei=Suzuki en-aut-mei=Etsuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Faculty of Health and Medical Sciences, University of Surrey kn-affil= affil-num=2 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=immortal time bias kn-keyword=immortal time bias en-keyword=principal stratification kn-keyword=principal stratification en-keyword=potential outcomes kn-keyword=potential outcomes en-keyword=causal inference kn-keyword=causal inference END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=24117 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250706 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Survival days of patients with metastatic spinal tumors of lung cancer requiring surgery: a prospective multicenter study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Surgery for metastatic spinal tumors has improved postoperative activities of daily living. A few studies reported on prognostic factors assessed in large multicenter prospective studies for metastatic spinal tumors of lung cancer origin. This study aimed to determine preoperative prognostic factors in patients undergoing surgery for metastatic spinal tumors associated with lung cancer. This prospective registry study included 74 patients diagnosed and operated with metastatic spine tumors derived from lung cancer in 39 high-volume cancer centers. We examined the postoperative survival period and the preoperative factors related to postoperative survival time. We conducted univariate and multivariate Cox regression analyses to determine preoperative prognostic factors. The mean postoperative survival period was 343 days. Multivariate Cox regression analysis revealed a higher feeding score of vitality index, indications for molecularly targeted therapy, and a higher mobility score of Barthel index as independent factors associated with postoperative survival time in metastatic spinal tumors derived from lung cancer. Patients with indications for molecular-targeted therapy and good vitality exhibited longer survival. These results may help in surgical selection for patients with metastatic spinal tumors derived from lung cancer. en-copyright= kn-copyright= en-aut-name=TakahashiTakuya en-aut-sei=Takahashi

en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: Postoperative lymphopenia is reported as an excellent indicator to predict surgical-site infection (SSI) after spine surgery. However, there is still controversy concerning which serological markers can predict spinal SSI. This study aims to evaluate excellent and early indicators for detecting SSI, focusing on spine instrumented surgery. Materials and Methods: This study included 268 patients who underwent spinal instrumented surgery from January 2022 to December 2023 (159 female and 109 male, average 62.9 years). The SSI group included 20 patients, and the non-SSI group comprised 248 patients. Surgical time, intraoperative blood loss, and glycemic levels were measured in both groups. The complete blood cell counts, differential counts, albumin, and C-reactive protein (CRP) levels were measured pre-surgery and postoperative on Days 1, 3, and 7. In comparing the groups, the Mann?Whitney U test analysis was used for continuous variables, while the chi-squared test and Fisher’s exact test were used for dichotomous variables. Results: The incidence of SSI after spinal instrumentation was 7.46% and was relatively higher in scoliosis surgery. The SSI group had significantly longer surgical times (248 min vs. 180 min, p = 0.0004) and a higher intraoperative blood loss (772 mL vs. 372 mL, p < 0.0001) than the non-SSI group. In the SSI group, the Day 3 (10.5 ± 6.2% vs. 13.8 ± 6.0%, p = 0.012) and Day 7 (14.4 ± 4.8% vs. 18.8 ± 7.1%, p = 0.012) lymphocyte ratios were lower than the non-SSI group. Albumin levels on Day 1 in the SSI group were lower than in the non-SSI group (2.94 ± 0.30 mg/dL vs. 3.09 ± 0.38 mg/dL, p = 0.045). There is no difference in CRP and lymphocyte count between the two groups. Conclusions: SSI patients had lower lymphocyte percentages than non-SSI patients, which was a risk factor for SSI, with constant high inflammation. The Day 3 lymphocyte percentage may predict SSI after spinal instrumented surgery. en-copyright= kn-copyright= en-aut-name=MiyamotoAkiyoshi en-aut-sei=Miyamoto en-aut-mei=Akiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaMasato en-aut-sei=Tanaka en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FloresAngel Oscar Paz en-aut-sei=Flores en-aut-mei=Angel Oscar Paz kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YuDongwoo en-aut-sei=Yu en-aut-mei=Dongwoo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=JainMukul en-aut-sei=Jain en-aut-mei=Mukul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HengChristan en-aut-sei=Heng en-aut-mei=Christan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KomatsubaraTadashi en-aut-sei=Komatsubara en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AratakiShinya en-aut-sei=Arataki en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OdaYoshiaki en-aut-sei=Oda en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ShinoharaKensuke en-aut-sei=Shinohara en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=UotaniKoji en-aut-sei=Uotani en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=2 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=3 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=4 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=5 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=6 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=7 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=8 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=9 en-affil=Department of Orthopedic Surgery, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Orthopedic Surgery, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Orthopedic Surgery, Okayama University Hospital kn-affil= en-keyword=surgical site infection kn-keyword=surgical site infection en-keyword=spine surgery kn-keyword=spine surgery en-keyword=instrumentation kn-keyword=instrumentation en-keyword=diagnosis kn-keyword=diagnosis en-keyword=lymphocyte kn-keyword=lymphocyte END start-ver=1.4 cd-journal=joma no-vol=60 cd-vols= no-issue=4 article-no= start-page=519 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240322 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Retrospective Cohort Study of Early versus Delayed Ballon Kyphoplasty Intervention for Osteoporotic Vertebral Fracture Treatment en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: To investigate the outcomes of early balloon kyphoplasty (BKP) intervention compared with late intervention for osteoporotic vertebral fracture (OVF). Background: Osteoporotic vertebral fracture can lead to kyphotic deformity, severe back pain, depression, and disturbances in activities of daily living (ADL). Balloon kyphoplasty has been widely utilized to treat symptomatic OVFs and has proven to be a very effective surgical option for this condition. Furthermore, BKP is relatively a safe and effective method due to its reduced acrylic cement leakage and greater kyphosis correction. Materials and Methods: A retrospective cohort study was conducted at our hospital for patients who underwent BKP for osteoporotic vertebral fractures in the time frame between January 2020 and December 2022. Ninety-nine patients were included in this study, and they were classified into two groups: in total, 36 patients underwent early BKP intervention (EI) at <4 weeks, and 63 patients underwent late BKP intervention (LI) at ?4 weeks. We performed a clinical, radiological and statistical comparative evaluation for the both groups with a mean follow-up of one year. Results: Adjacent segmental fractures were more frequently observed in the LI group compared to the EI group (33.3% vs. 13.9%, p = 0.034). There was a significant improvement in postoperative vertebral angles in both groups (p = 0.036). The cement volume injected was 7.42 mL in the EI, compared with 6.3 mL in the LI (p = 0.007). The mean surgery time was shorter in the EI, at 30.2 min, compared with 37.1 min for the LI, presenting a significant difference (p = 0.0004). There was no statistical difference in the pain visual analog scale (VAS) between the two groups (p = 0.711), and there was no statistical difference in cement leakage (p = 0.192). Conclusions/Level of Evidence: Early BKP for OVF treatment may achieve better outcomes and fewer adjacent segmental fractures than delayed intervention. en-copyright= kn-copyright= en-aut-name=MiyamotoAkiyoshi en-aut-sei=Miyamoto en-aut-mei=Akiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=PariharUmesh en-aut-sei=Parihar en-aut-mei=Umesh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KumawatChetan en-aut-sei=Kumawat en-aut-mei=Chetan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=El Kader Al AskarAbd en-aut-sei=El Kader Al Askar en-aut-mei=Abd kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanakaMasato en-aut-sei=Tanaka en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=GunjotikarSharvari en-aut-sei=Gunjotikar en-aut-mei=Sharvari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TaokaTakuya en-aut-sei=Taoka en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KomatsubaraTadashi en-aut-sei=Komatsubara en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FujiwaraYoshihiro en-aut-sei=Fujiwara en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=UotaniKoji en-aut-sei=Uotani en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=AratakiShinya en-aut-sei=Arataki en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=9 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=10 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= en-keyword=ballon kyphoplasty kn-keyword=ballon kyphoplasty en-keyword=osteoporotic vertebral fractures kn-keyword=osteoporotic vertebral fractures en-keyword=kyphosis kn-keyword=kyphosis END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=2 article-no= start-page=euaf024 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202502 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=SCN5A variant type-dependent risk prediction in Brugada syndrome en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aims The variant in SCN5A with the loss of function (LOF) effect in the cardiac Na+ channel (Nav1.5) is the definitive cause for Brugada syndrome (BrS), and the functional analysis data revealed that LOF variants are associated with poor prognosis. However, which variant types (e.g. missense or non-missense) affect the prognoses of those variant carriers remain unelucidated.
Methods and results We defined SCN5A LOF variants as all non-missense and missense variants that produce peak INa < 65% of wild-type previously confirmed by patch-clamp studies. The study population consisted of 76 Japanese BrS patients (74% patients were male and the median age [IQR] at diagnosis was 28 [14?45] years) with LOF type of SCN5A variants: 40 with missense and 36 with non-missense variants. Non-missense variant carriers presented significantly more severe cardiac conduction disorder compared to the missense variant carriers. During follow-up periods of 9.0 [5.0?14.0] years, compared to missense variants, non-missense variants were significant risk factors of lifetime lethal arrhythmia events (LAEs) (P = 0.023). When focusing only on the missense variants that produce no peak INa, these missense variant carriers exhibited the same clinical outcomes as those with non-missense (log-rank P = 0.325). After diagnosis, however, both variant types were comparable in risk of LAEs (P = 0.155).
Conclusion We identified, for the first time, that SCN5A non-missense variants were associated with higher probability of LAE than missense variants in BrS patients though it did not change significantly after diagnosis. en-copyright= kn-copyright= en-aut-name=AizawaTakanori en-aut-sei=Aizawa en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID=

robot-assisted partial nephrectomy for small renal cell carcinoma: a retrospective cost analysis at Japanese single-institution en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: No direct cost comparison has been conducted between percutaneous cryoablation (PCA) and robot-assisted partial nephrectomy (RAPN) for clinical T1a renal cell carcinoma (RCC) in Japan. This study aimed to compare their costs.
Methods: We retrospectively analyzed data from 212 PCAs (including 155 with transcatheter arterial embolization) and 119 RAPN cases performed between December 2017 and May 2022.
Results: PCA patients were older with higher American Society of Anesthesiologists scores, Charlson Comorbidity Index, and history of previous RCC treatment, cardiovascular disease, and antithrombotic drug use than RAPN patients. PCA was associated with a significantly shorter procedure time and hospitalization duration with fewer major complications than those associated with RAPN. While PCA incurred a slightly lower total cost (1,123,000 vs. 1,155,000 yen), it had a significantly higher procedural cost (739,000 vs. 693,000 yen) and markedly worse total (? 93,000 vs. 249,000 yen) and procedural income-expenditure balance (? 189,000 vs. 231,000 yen) than those of RAPN. After statistical adjustment, PCA demonstrated significantly higher total (difference: 114,000 yen) and procedural costs (difference: 72,000 yen), alongside significantly worse total (difference: ? 358,000 yen) and procedural income-expenditure balances (difference: ? 439,000 yen). The incremental cost-effectiveness ratio was more favorable for PCA than for RAPN.
Conclusion: For high- risk patients, PCA demonstrated a safer option with shorter hospitalization duration than those of RAPN. Although PCA was more cost-effective, its higher procedural cost and unfavorable income-expenditure balance require careful evaluation, especially for large tumors that require three or more needles. en-copyright= kn-copyright= en-aut-name=UkaMayu en-aut-sei=Uka en-aut-mei=Mayu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IguchiToshihiro en-aut-sei=Iguchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=BekkuKensuke en-aut-sei=Bekku en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamanoiTomoaki en-aut-sei=Yamanoi en-aut-mei=Tomoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=GobaraHideo en-aut-sei=Gobara en-aut-mei=Hideo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=UmakoshiNoriyuki en-aut-sei=Umakoshi en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KawabataTakahiro en-aut-sei=Kawabata en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TomitaKoji en-aut-sei=Tomita en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MatsuiYusuke en-aut-sei=Matsui en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=ArakiMotoo en-aut-sei=Araki en-aut-mei=Motoo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=HirakiTakao en-aut-sei=Hiraki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=6 en-affil=Division of Medical Informatics, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=11 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Renal cancer kn-keyword=Renal cancer en-keyword=Cryoablation kn-keyword=Cryoablation en-keyword=Robot-assisted partial nephrectomy kn-keyword=Robot-assisted partial nephrectomy en-keyword=Cost kn-keyword=Cost en-keyword=Cost effectiveness kn-keyword=Cost effectiveness END start-ver=1.4 cd-journal=joma no-vol=144-145 cd-vols= no-issue= article-no= start-page=109001 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202505 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Investigating the fate of Zirconium-89 labelled antibody in cynomolgus macaques en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Preclinical pharmacokinetic studies of therapeutic antibodies in non-human primates are desired because of the difficulty in extrapolating ADME data from animal models to humans. We evaluated the pharmacokinetics of 89Zr (Zirconium-89) -labelled anti-KLH human IgG and its metabolites to confirm their non-specific/physiological accumulation in healthy cynomolgus macaques. The anti-KLH antibody was used as a negative control, ensuring that the observed distribution reflected general IgG behavior rather than antigen-specific accumulation. This provides a valuable reference for comparing the biodistribution of targeted antibodies.
Methods: Selected IgG was conjugated to desferrioxamine (DFO), labelled with 89Zr, and injected into healthy cynomolgus macaques. PET/CT images at the whole-body level were acquired at different time points, and standard uptake values (SUV) in regions of interest, such as the heart, liver, spleen, kidneys, bone, and muscles, were calculated. The distribution of a shortened antibody variant, 89Zr-labelled Fab, as well as that of [89Zr]Zr-DFO and [89Zr]Zr-oxalate, the expected metabolites of 89Zr- labelled IgG, was also assessed.
Results: After 89Zr-labelled IgG injection, the SUV in the heart, vertebral body, and muscle decreased, in line with the 89Zr concentration decrease in the circulation, whereas radioactivity increased over time in the kidneys and liver. Autoradiography of the renal sections indicated that most of the 89Zr- labelled IgG radioactivity accumulated in the renal cortex. Relatively high accumulation in the kidneys was also observed in 89Zr- labelled Fab-injected macaques, and renal autoradiographs of these animals showed that the renal cortex was the preferred accumulation site. However, [89Zr]Zr-DFO was rapidly excreted into the urine, whereas [89Zr]Zr-oxalate was highly accumulated in the epiphysis of the long bones and vertebral body.
Conclusion: In the non-human primate cynomolgus macaque, 89Zr- labelled IgG accumulated in the kidneys and the liver. However, [89Zr]Zr-DFO and 89Zr did not accumulate in these organs. This preclinical pharmacokinetic study performed with human IgG in a non-human primate model using PET is of great significance as it sheds light on the basic fate and distribution of 89Zr- labelled IgG. en-copyright= kn-copyright= en-aut-name=SasakiTakanori en-aut-sei=Sasaki en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KimuraSadaaki en-aut-sei=Kimura en-aut-mei=Sadaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NodaAkihiro en-aut-sei=Noda en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MurakamiYoshihiro en-aut-sei=Murakami en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyoshiSosuke en-aut-sei=Miyoshi en-aut-mei=Sosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AkehiMasaru en-aut-sei=Akehi en-aut-mei=Masaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OchiaiKazuhiko en-aut-sei=Ochiai en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=WatanabeMasami en-aut-sei=Watanabe en-aut-mei=Masami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HiguchiTakahiro en-aut-sei=Higuchi en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MatsuuraEiji en-aut-sei=Matsuura en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Astellas Pharma Inc. kn-affil= affil-num=3 en-affil=Astellas Pharma Inc. kn-affil= affil-num=4 en-affil=Astellas Pharma Inc. kn-affil= affil-num=5 en-affil=Astellas Pharma Inc. kn-affil= affil-num=6 en-affil=Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=School of Veterinary Nursing and Technology, Faculty of Veterinary Science, Nippon Veterinary and Life Science University kn-affil= affil-num=8 en-affil=Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=PET imaging kn-keyword=PET imaging en-keyword=Zirconium-89 kn-keyword=Zirconium-89 en-keyword=Therapeutic antibodies kn-keyword=Therapeutic antibodies en-keyword=Non-human primates kn-keyword=Non-human primates END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=6 article-no= start-page=1711 end-page=1720 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202506 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Dotinurad Treatment for Patients With Hyperuricemia Complicating CKD en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: The management of hyperuricemia is important to reduce cardiovascular risk and the progression of renal injury in chronic kidney disease (CKD). This study aimed to assess the efficacy and safety of dotinurad, a novel urate transporter-1 inhibitor, in patients with hyperuricemia and CKD.
Methods: In a nonrandomized, parallel interventional study, patients were grouped based on their estimated glomerular filtration rate (eGFR) at baseline. The starting dotinurad dose was 0.5 mg/d and titrated to a final dose of 2 mg/d to 4 mg/d. The primary end point was the noninferiority of the change in serum uric acid (UA) levels between the G1/G2 and G3/G4 groups at week 24. The main secondary end points were changes in eGFR and UA clearance-to-creatinine clearance ratio (CUA/CCr). Reported adverse events were also investigated.
Results: Ninety-eight patients continued the dose titration. The mean percentage reduction in serum UA level at week 24 were 47.2% and 42.8% for the G1/G2 and G3/G4 groups, respectively; the between-group difference was ?4.3% (95% confidence interval [CI], ?9.5% to 0.9%, noninferiority P = 0.0321), validating the noninferiority of treatment in the G3/G4 group to the G1/G2 group. eGFR tended to increase slightly through to week 24, suggesting that spontaneous eGFR decline was counteracted. Mean CUA/CCr generally increased over time from week 4 to week 24. No new safety issues of particular concern were identified; and there were no marked changes in urinary pH.
Conclusion: Dotinurad therapy may be well-tolerated in patients with hyperuricemia and may have efficacy comparable with existing standard treatment in patients with CKD stages G3/G4. Randomized controlled trials in larger patient groups are needed. en-copyright= kn-copyright= en-aut-name=TanabeKatsuyuki en-aut-sei=Tanabe en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NunoueTomokazu en-aut-sei=Nunoue en-aut-mei=Tomokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ItabashiNaoki en-aut-sei=Itabashi en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KatayamaAkihiro en-aut-sei=Katayama en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakamuraAkihiko en-aut-sei=Nakamura en-aut-mei=Akihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OhbayashiHiroyuki en-aut-sei=Ohbayashi en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OnishiYasuhiro en-aut-sei=Onishi en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=WatanabeKyoko en-aut-sei=Watanabe en-aut-mei=Kyoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MaruyamaKeisuke en-aut-sei=Maruyama en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HosoyaTakeshi en-aut-sei=Hosoya en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OkadaShinichi en-aut-sei=Okada en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Nunoue Clinic kn-affil= affil-num=3 en-affil=Itabashi Diabetes and Dermatology Medical Clinic kn-affil= affil-num=4 en-affil=NHO Okayama Medical Center kn-affil= affil-num=5 en-affil=Osafune Clinic kn-affil= affil-num=6 en-affil=Tohno Chuo Clinic kn-affil= affil-num=7 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Japanese Red Cross Okayama Hospital kn-affil= affil-num=9 en-affil=Okayama Saiseikai Outpatient Center Hospital kn-affil= affil-num=10 en-affil=Hosoya Clinic kn-affil= affil-num=11 en-affil=Okada Medical Clinic kn-affil= affil-num=12 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=chronic kidney disease kn-keyword=chronic kidney disease en-keyword=dotinurad kn-keyword=dotinurad en-keyword=efficacy kn-keyword=efficacy en-keyword=hyperuricemia kn-keyword=hyperuricemia en-keyword=safety kn-keyword=safety en-keyword=serum uric acid kn-keyword=serum uric acid END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=3 article-no= start-page=444 end-page=451 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250630 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=More postoperative complications and revision surgery after occipitocervical fusion than after atlantoaxial fusion: a retrospective multicenter cohort study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Study Design: A retrospective multicenter cohort study.
Purpose: We sought to determine whether occipitocervical (OC) fusion is followed by more postoperative complications and revision surgery than is atlantoaxial (AA) fusion. We aim to compare postoperative complications and revision surgery associated with OC fusion and AA fusion.
Overview of Literature: OC and AA fusion are established techniques for restoring upper cervical stability. However, the outcomes of the two methods have not been compared.
Methods: This study included 90 patients who underwent upper spinal fusion surgery for mechanical instability, performed by three surgeons in two hospitals from 2011 to 2023; OC fusion was indicated for irreducible AA subluxation, os odontoideum, and severe upper C1 fracture. Of the patients, 38 (mean age, 58.7 years) underwent OC fusion, and 52 (mean age, 62.8 years) underwent AA fusion. To evaluate surgical outcomes, we documented surgical time, intraoperative blood loss, postoperative complications, and the rate of revision surgery. Radiographs were obtained to identify screw malposition, rod breakage, and nonunion. To compare the outcomes of the two techniques, we used the Mann-Whitney U test for continuous variables and the chi-square or Fisher’s exact test for dichotomous variables.
Results: OC fusion took significantly longer (175.4 minutes) than AA fusion (150.7 minutes, p=0.020) and had a higher complication rate (39.5% vs. 11.5%, p<0.0001). The reoperation rate was 23.7% (9/38) after OC fusion and 3.8% (2/52) after AA fusion; the difference was statistically significant (p=0.0073). Average amounts of blood loss were 224 mL during OC fusion and 224 mL during AA fusion; the difference was not significant (p=0.947).
Conclusions: Although OC fusion is indispensable for certain conditions, particularly basilar invagination, it entails more risk than dose AA fusion; the choice of technique thus warrants careful consideration. en-copyright= kn-copyright= en-aut-name=UotaniKoji en-aut-sei=Uotani en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FloresAngel Oscar Paz en-aut-sei=Flores en-aut-mei=Angel Oscar Paz kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaMasato en-aut-sei=Tanaka en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=EkadeShashank J en-aut-sei=Ekade en-aut-mei=Shashank J kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AratakiShinya en-aut-sei=Arataki en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KomatsubaraTadashi en-aut-sei=Komatsubara en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OdaYoshiaki en-aut-sei=Oda en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ShinoharaKensuke en-aut-sei=Shinohara en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= en-keyword=Occipitocervical fusion kn-keyword=Occipitocervical fusion en-keyword=Atlantoaxial fusion kn-keyword=Atlantoaxial fusion en-keyword=Upper cervical instability kn-keyword=Upper cervical instability en-keyword=Surgical complication kn-keyword=Surgical complication en-keyword=Reoperation kn-keyword=Reoperation END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=7 article-no= start-page=e88945 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250728 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Six-Year Remission With No Relapse After Four-Time Weekly Rituximab Only for Bilateral Ocular Adnexal Follicular Lymphoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Follicular lymphoma mostly takes an indolent course, and thus, observation with watchful waiting is a main therapeutic strategy. Recent long-term studies suggest earlier treatment with rituximab monotherapy may benefit patients by delaying the need for treatment in the later phase of exacerbation. In this study, we reported a patient with bilateral orbital follicular lymphoma who received four-time weekly rituximab monotherapy as an induction therapy only and maintained the remission for 5 years with no treatment. The patient was a 51-year-old woman who developed a right upper orbital mass and was diagnosed with follicular lymphoma grade 1 by the excisional biopsy. Two years later, at the age of 53 years, she developed a left lacrimal gland mass and underwent excision. The pathological diagnosis was follicular lymphoma grade 1. She did not have any other systemic lesions by fluorodeoxyglucose positron emission tomography. At the age of 54 years, she developed a new mass on the nasal side of the right orbit and underwent weekly rituximab monotherapy (375 mg/m2) four times a month, leading to the reduction of the mass in 3 months. Two high uptake sites on the temporal and nasal side of the right superior orbit by fluorodeoxyglucose positron emission tomography disappeared one year later at the age of 55 years. She was followed with no treatment for 6 years until the age of 60 years at the latest visit. In case of a local orbital relapse, local radiotherapy would be the standard, but rituximab monotherapy as an induction therapy only was chosen in the present patient. Rituximab monotherapy in place of local radiotherapy would be a treatment option for orbital follicular lymphoma. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiiNobuharu en-aut-sei=Fujii en-aut-mei=Nobuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Ophthalmology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University, and Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Pathology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Division of Transfusion and Cell Therapy, Department of Hematology and Oncology, Okayama University Hospital kn-affil= en-keyword=claustrophobia kn-keyword=claustrophobia en-keyword=extranodal marginal zone b-cell lymphoma mucosa-associated lymphoid tissue (malt) type kn-keyword=extranodal marginal zone b-cell lymphoma mucosa-associated lymphoid tissue (malt) type en-keyword=fluorodeoxyglucose positron emission tomography kn-keyword=fluorodeoxyglucose positron emission tomography en-keyword=follicular lymphoma kn-keyword=follicular lymphoma en-keyword=magnetic resonance imaging kn-keyword=magnetic resonance imaging en-keyword=mucosaassociated lymphoid tissue (malt) lymphoma kn-keyword=mucosaassociated lymphoid tissue (malt) lymphoma en-keyword=ocular adnexa kn-keyword=ocular adnexa en-keyword=orbital mass kn-keyword=orbital mass en-keyword=radiotherapy kn-keyword=radiotherapy en-keyword=rituximab kn-keyword=rituximab END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=11 article-no= start-page=uhae248 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240904 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A low-cost dpMIG-seq method for elucidating complex inheritance in polysomic crops: a case study in tetraploid blueberry en-subtitle= kn-subtitle= en-abstract= kn-abstract=Next-generation sequencing (NGS) library construction often requires high-quality DNA extraction, precise adjustment of DNA concentration, and restriction enzyme digestion to reduce genome complexity, which results in increased time and cost in sample preparation and processing. To address these challenges, a PCR-based method for rapid NGS library preparation, named dpMIG-seq, has been developed and proven effective for high-throughput genotyping. However, the application of dpMIG-seq has been limited to diploid and polyploid species with disomic inheritance. In this study, we obtained genome-wide single nucleotide polymorphism (SNP) markers for tetraploid blueberry to evaluate genotyping and downstream analysis outcomes. Comparison of genotyping qualities inferred across samples with different DNA concentrations and multiple bioinformatics approaches revealed high accuracy and reproducibility of dpMIG-seq-based genotyping, with Pearson's correlation coefficients between replicates in the range of 0.91 to 0.98. Furthermore, we demonstrated that dpMIG-seq enables accurate genotyping of samples with low DNA concentrations. Subsequently, we applied dpMIG-seq to a tetraploid F1 population to examine the inheritance probability of parental alleles. Pairing configuration analysis supported the random meiotic pairing of homologous chromosomes on a genome-wide level. On the other hand, preferential pairing was observed on chr-11, suggesting that there may be an exception to the random pairing. Genotypic data suggested quadrivalent formation within the population, although the frequency of quadrivalent formation varied by chromosome and cultivar. Collectively, the results confirmed applicability of dpMIG-seq for allele dosage genotyping and are expected to catalyze the adoption of this cost-effective and rapid genotyping technology in polyploid studies. en-copyright= kn-copyright= en-aut-name=NagasakaKyoka en-aut-sei=Nagasaka en-aut-mei=Kyoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishimuraKazusa en-aut-sei=Nishimura en-aut-mei=Kazusa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MotokiKo en-aut-sei=Motoki en-aut-mei=Ko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamagataKeigo en-aut-sei=Yamagata en-aut-mei=Keigo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishiyamaSoichiro en-aut-sei=Nishiyama en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamaneHisayo en-aut-sei=Yamane en-aut-mei=Hisayo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TaoRyutaro en-aut-sei=Tao en-aut-mei=Ryutaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakanoRyohei en-aut-sei=Nakano en-aut-mei=Ryohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakazakiTetsuya en-aut-sei=Nakazaki en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=5 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=6 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=7 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=8 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=9 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=94 cd-vols= no-issue=1 article-no= start-page=64 end-page=72 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=2025 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Development of an AI-based Image Analysis System to Calculate the Visit Duration of a Green Blow Fly on a Strawberry Flower en-subtitle= kn-subtitle= en-abstract= kn-abstract=Pollinator insects are required to pollinate flowers in the production of some fruits and vegetables, and strawberries fall into this category. However, the function of pollinators has not been clarified by quantitative metrics such as the duration of pollinator visits needed by flowers. Due to the long activity time of pollinators (approximately 10-h), it is not easy to observe the visitation characteristics manually. Therefore, we developed software for evaluating pollinator performance using two types of artificial intelligence (AI), YOLOv4, which is an object detection AI, and VGG16, which is an image classifier AI. In this study, we used Phaenicia sericata Meigen (green blow fly) as the strawberry pollinator. The software program can automatically estimate the visit duration of a fly on a flower from video clips. First, the position of the flower is identified using YOLO, and the identified location is cropped. Next, the cropped image is classified by VGG16 to determine if the fly is on the flower. Finally, the results are saved in CSV and HTML format. The program processed 10 h of video (collected from 07:00 h to 17:00 h) taken under actual growing conditions to estimate the visit durations of flies on flowers. The recognition accuracy was approximately 97%, with an average difference of 550 s. The software was run on a small computer board (the Jetson Nano), indicating that it can easily be used without a complicated AI configuration. This means that the software can be used immediately by distributing pre-configured disk images. When the software was run on the Jetson Nano, it took approximately 11 min to estimate one day of 2-h video. It is therefore clear that the visit duration of a fly on a flower can be estimated much faster than by manually checking videos. Furthermore, this system can estimate the visit durations of pollinators to other flowers by changing the YOLO and VGG16 model files. en-copyright= kn-copyright= en-aut-name=TaniguchiHiroki en-aut-sei=Taniguchi en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsukudaYuki en-aut-sei=Tsukuda en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MotokiKo en-aut-sei=Motoki en-aut-mei=Ko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=GotoTanjuro en-aut-sei=Goto en-aut-mei=Tanjuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YoshidaYuichi en-aut-sei=Yoshida en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YasubaKen-ichiro en-aut-sei=Yasuba en-aut-mei=Ken-ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=School of Agriculture Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=deep learning kn-keyword=deep learning en-keyword=fly kn-keyword=fly en-keyword=microcomputer kn-keyword=microcomputer en-keyword=VGG16 kn-keyword=VGG16 en-keyword=YOLO kn-keyword=YOLO END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=66 end-page=73 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241106 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=kdMonitor: Kernel Data Monitor for Detecting Kernel Memory Corruption en-subtitle= kn-subtitle= en-abstract= kn-abstract=Privilege escalation attacks through memory corruption via kernel vulnerabilities pose significant threats to operating systems. Although the extended Berkley Packet Filter has been employed to trace kernel code execution by inserting interrupts before and after kernel code invocations, it does not track operations before and after kernel data writes, thus hindering effective kernel data monitoring. In this study, we introduce a kernel data monitor (kdMonitor), which is a novel security mechanism designed to detect unauthorized alterations in the monitored kernel data of a dedicated kernel page. The kdMonitor incorporates two distinct methods. The first is periodic monitoring which regularly outputs the monitored kernel data of the dedicated kernel pages. The second is dynamic monitoring, which restricts write access to a dedicated kernel page, supplements any write operations with page faults, and outputs the monitored kernel data of dedicated kernel pages. kdMonitor enables real-time tracking of specified kernel data of the dedicated kernel page residing in the kernel's virtual memory space from the separated machine. Using kdMonitor, we demonstrated its capability to pinpoint tampering with user process privileged information stemming from privilege escalation attacks on the kernel. Through an empirical evaluation, we validated the effectiveness of kdMonitor in detecting privilege escalation attacks by user processes on Linux. Performance assessments revealed that kdMonitor achieved an attack detection time of 0.83 seconds with an overhead of 0.726 %. en-copyright= kn-copyright= en-aut-name=KuzunoHiroki en-aut-sei=Kuzuno en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamauchiToshihiro en-aut-sei=Yamauchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Engineering, Kobe University kn-affil= affil-num=2 en-affil=Okayama University,Faculty of Environmental, Life, Natural Science and Technology kn-affil= en-keyword=Vulnerability countermeasure kn-keyword=Vulnerability countermeasure en-keyword=Operating system security kn-keyword=Operating system security en-keyword=System security kn-keyword=System security END start-ver=1.4 cd-journal=joma no-vol=57 cd-vols= no-issue=1 article-no= start-page=21 end-page=33 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250724 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Market Reactions to Earnings Announcements in Profitable and Loss Firm-Quarters: Changes Around the Market Restructuring kn-title=黒字企業と赤字企業における決算発表に対する市場の反応―市場区分変更前後における分析― en-subtitle= kn-subtitle= en-abstract= kn-abstract=The purpose of this paper is to examine whether the market reaction to earnings announcements in each market segment （prime market segment, standard market segment, and growth market segment） differs between profitable and loss-making firms around the time of market restructuring. We have previously studied market reactions to quarterly earnings announcements in the context of the revision of market segmentation at the Tokyo Stock Exchange. However, we have not studied the differences between profitable firm quarters and loss firm quarters. Therefore, the analysis in this paper focuses on whether the net income attributable to owners of the parent is positive or negative. In the growth market segment, significant differences between profitable and loss-making firms were observed in the results of the analysis. en-copyright= kn-copyright= en-aut-name=NakagawaToyotaka en-aut-sei=Nakagawa en-aut-mei=Toyotaka kn-aut-name=中川豊隆 kn-aut-sei=中川 kn-aut-mei=豊隆 aut-affil-num=1 ORCID= en-aut-name=YamanishiYuki en-aut-sei=Yamanishi en-aut-mei=Yuki kn-aut-name=山西佑季 kn-aut-sei=山西 kn-aut-mei=佑季 aut-affil-num=2 ORCID= en-aut-name=KobayashiHiroaki en-aut-sei=Kobayashi en-aut-mei=Hiroaki kn-aut-name=小林裕明 kn-aut-sei=小林 kn-aut-mei=裕明 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil=熊本県立大学総合管理学部 affil-num=3 en-affil= kn-affil=青山学院大学大学院会計プロフェッション研究科 END start-ver=1.4 cd-journal=joma no-vol=65 cd-vols= no-issue=7 article-no= start-page=319 end-page=325 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250715 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Nationwide Survey of Middle Meningeal Artery Embolization for Chronic Subdural Hematoma in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Middle meningeal artery embolization has increasingly been used to treat chronic subdural hematoma. However, the current state of its application and outcomes in Japan remains unclear. We conducted a multicenter observational study involving facilities affiliated with the Japanese Society for Neuroendovascular Therapy to assess current practices and clarify the usefulness and safety of middle meningeal artery embolization for chronic subdural hematoma. A total of 466 patients from 40 facilities were included. The mean age of the patients was 78.0 ± 10.5 years, and bleeding risks, including antithrombotic therapy or bleeding predisposition, were present in 36.1% of patients. The most common timing for middle meningeal artery embolization was after the second burr hole surgery, accounting for 34.8% of cases. N-butyl-2-cyanoacrylate was used as the embolic material in 67% of cases. The complication rate was 5.2%, with complication-related morbidity at 0.9%. Hematomas were stable in 91.5% of cases at 30 days post-middle meningeal artery embolization. The symptomatic recurrence rate was 8.9%. Cases that underwent middle meningeal artery embolization after the second or subsequent burr hole surgeries were significantly associated with symptomatic recurrence. This study is the first nationwide survey investigating the real-world clinical practice of middle meningeal artery embolization for chronic subdural hematoma in Japan. While it included many elderly patients, recurrent cases, and those with bleeding risks, the safety and usefulness of middle meningeal artery embolization were deemed acceptable. However, symptomatic recurrence was common even in cases with middle meningeal artery embolization when performed after the second or subsequent burr hole surgeries. A further prospective study will be warranted to clarify treatment indications, optimal timing, and treatment techniques of middle meningeal artery embolization. en-copyright= kn-copyright= en-aut-name=MURAISatoshi en-aut-sei=MURAI en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=EBISUDANIYuki en-aut-sei=EBISUDANI en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HARUMAJun en-aut-sei=HARUMA en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HIRAMATSUMasafumi en-aut-sei=HIRAMATSU en-aut-mei=Masafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HISHIKAWATomohito en-aut-sei=HISHIKAWA en-aut-mei=Tomohito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SATOWTetsu en-aut-sei=SATOW en-aut-mei=Tetsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SUGIUKenji en-aut-sei=SUGIU en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Neurosurgery, Kawasaki Medical School kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Neurosurgery, Kawasaki Medical School kn-affil= affil-num=6 en-affil=Department of Neurosurgery/Stroke Center, Kindai University Hospital kn-affil= affil-num=7 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=chronic subdural hematoma kn-keyword=chronic subdural hematoma en-keyword=endovascular therapy kn-keyword=endovascular therapy en-keyword=middle meningeal artery kn-keyword=middle meningeal artery END start-ver=1.4 cd-journal=joma no-vol=351 cd-vols= no-issue= article-no= start-page=199522 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202501 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evidence for the replication of a plant rhabdovirus in its arthropod mite vector en-subtitle= kn-subtitle= en-abstract= kn-abstract=Transmission of plant viruses that replicate in the insect vector is known as persistent-propagative manner. However, it remains unclear whether such virus-vector relationships also occur between plant viruses and other biological vectors such as arthropod mites. In this study, we investigated the possible replication of orchid fleck virus (OFV), a segmented plant rhabdovirus, within its mite vector (Brevipalpus californicus s.l.) using quantitative RT-qPCR, western blotting and next-generation sequencing. Time-course RT-qPCR and western blot analyses showed an increasing OFV accumulation pattern in mites after virus acquisition. Since OFV genome expression requires the transcription of polyadenylated mRNAs, polyadenylated RNA fractions extracted from the viruliferous mite samples and OFV-infected plant leaves were used for RNA-seq analysis. In the mite and plant datasets, a large number of sequence reads were aligned to genomic regions of OFV RNA1 and RNA2 corresponding to transcribed viral gene mRNAs. This includes the short polyadenylated transcripts originating from the leader and trailer regions at the ends of the viral genome, which are believed to play a crucial role in viral transcription/replication. In contrast, a low number of reads were mapped to the non-transcribed regions (gene junctions). These results strongly suggested that OFV gene expression occurs both in mites and plants. Additionally, deep sequencing revealed the accumulation of OFV-derived small RNAs in mites, although their size profiles differ from those found in plants. Taken together, our results indicated that OFV replicates within a mite vector and is targeted by the RNA-silencing mechanism. en-copyright= kn-copyright= en-aut-name=KondoHideki en-aut-sei=Kondo en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujitaMiki en-aut-sei=Fujita en-aut-mei=Miki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TelengechPaul en-aut-sei=Telengech en-aut-mei=Paul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MaruyamKazuyuki en-aut-sei=Maruyam en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HyodoKiwamu en-aut-sei=Hyodo en-aut-mei=Kiwamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TassiAline Daniele en-aut-sei=Tassi en-aut-mei=Aline Daniele kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OchoaRonald en-aut-sei=Ochoa en-aut-mei=Ronald kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AndikaIda Bagus en-aut-sei=Andika en-aut-mei=Ida Bagus kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SuzukiNobuhiro en-aut-sei=Suzuki en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=4 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=5 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=6 en-affil=Tropical Research and Education Center, University of Florida kn-affil= affil-num=7 en-affil=Systematic Entomology Laboratory, USDA kn-affil= affil-num=8 en-affil=College of Plant Protection, Northwest A&F University kn-affil= affil-num=9 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= en-keyword=Rhabdovirus kn-keyword=Rhabdovirus en-keyword=Plant kn-keyword=Plant en-keyword=Mite kn-keyword=Mite en-keyword=Vector kn-keyword=Vector en-keyword=Replication kn-keyword=Replication en-keyword=mRNA kn-keyword=mRNA en-keyword=Small RNA kn-keyword=Small RNA END start-ver=1.4 cd-journal=joma no-vol=186 cd-vols= no-issue= article-no= start-page=118030 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202505 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=(+)-Terrein exerts anti-obesity and anti-diabetic effects by regulating the differentiation and thermogenesis of brown adipocytes in mice fed a high-fat diet en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: (+)-Terrein, a low-molecular-weight secondary metabolite from Aspergillus terreus, inhibits adipocyte differentiation in vitro. However, the precise mechanisms underlying the effects of (+)-terrein on adipocytes remain unclear. We hypothesized that (+)-terrein modulates adipogenesis and glucose homeostasis in obesity and diabetes via anti-inflammatory action and regulation of adipocyte differentiation. Hence, in this study, we aimed to investigate the in vivo anti-diabetic and anti-obesity effects of (+)-terrein.
Methods: Male C57BL/6?J mice were fed normal chow or high-fat (HF) diet and administered (+)-terrein (180?mg/kg) via intraperitoneal injection. Glucose and insulin tolerance tests, serum biochemical assays, and histological analyses were also performed. Rat brown preadipocytes, mouse brown preadipocytes (T37i cells), and inguinal white adipose tissue (ingWAT) preadipocytes were exposed to (+)-terrein during in vitro adipocyte differentiation. Molecular markers associated with thermogenesis and differentiation were quantified using real-time polymerase chain reaction and western blotting.
Results: (+)-Terrein-treated mice exhibited improved insulin sensitivity and reduced serum lipid and glucose levels, irrespective of the diet. Furthermore, (+)-terrein suppressed body weight gain and mitigated fat accumulation by activating brown adipose tissue in HF-fed mice. (+)-Terrein facilitated the in vitro differentiation of rat brown preadipocytes, T37i cells, and ingWAT preadipocytes by upregulating peroxisome proliferator-activated receptor-γ (PPARγ). This effect was synergistic with that of a PPARγ agonist.
Conclusion: This study demonstrated that (+)-terrein effectively induces PPARγ expression and brown adipocyte differentiation, leading to reduced weight gain and improved glucose and lipid profiles in HF-fed mice. Thus, (+)-terrein is a potent novel agent with potential anti-obesity and anti-diabetic properties. en-copyright= kn-copyright= en-aut-name=Aoki-SaitoHaruka en-aut-sei=Aoki-Saito en-aut-mei=Haruka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MandaiHiroki en-aut-sei=Mandai en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakakuraTakashi en-aut-sei=Nakakura en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SasakiTsutomu en-aut-sei=Sasaki en-aut-mei=Tsutomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KitamuraTadahiro en-aut-sei=Kitamura en-aut-mei=Tadahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OmoriKazuhiro en-aut-sei=Omori en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HisadaTakeshi en-aut-sei=Hisada en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OkadaShuichi en-aut-sei=Okada en-aut-mei=Shuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SugaSeiji en-aut-sei=Suga en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=YamadaMasanobu en-aut-sei=Yamada en-aut-mei=Masanobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=SaitoTsugumichi en-aut-sei=Saito en-aut-mei=Tsugumichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Allergy and Respiratory Medicine, Gunma University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Pharmacy, Faculty of Pharmacy, Gifu University of Medical Science kn-affil= affil-num=3 en-affil=Department of Anatomy, Teikyo University School of Medicine kn-affil= affil-num=4 en-affil=Division of Food Science and Biotechnology, Graduate School of Agriculture, Kyoto University kn-affil= affil-num=5 en-affil=Metabolic Signal Research Center, Institute for Molecular and Cellular Regulation, Gunma University kn-affil= affil-num=6 en-affil=Department of Pathophysiology-Periodontal Science, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Gunma University Graduate School of Health Sciences kn-affil= affil-num=8 en-affil=Department of Diabetes, Soleiyu Asahi Clinic kn-affil= affil-num=9 en-affil=Division of Applied Chemistry, Graduate School of Natural Sciences and Technology, Okayama University kn-affil= affil-num=10 en-affil=Department of Medicine and Molecular Science, Gunma University Graduate School of Medicine kn-affil= affil-num=11 en-affil=Department of Health & Sports Sciences, Faculty of Education, Tokyo Gakugei University kn-affil= en-keyword=(+)-Terrein kn-keyword=(+)-Terrein en-keyword=Brown adipose tissue kn-keyword=Brown adipose tissue en-keyword=Thermogenesis kn-keyword=Thermogenesis en-keyword=Obesity kn-keyword=Obesity en-keyword=PPARγ kn-keyword=PPARγ END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=23 article-no= start-page=17720 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=2025 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A meta-linked isomer of ITIC: influence of aggregation patterns on open-circuit voltage in organic solar cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Improving the open-circuit voltage (VOC) of organic solar cells (OSCs) remains an important challenge. While it is known that the energy levels at the donor/acceptor (D/A) interface affect the VOC, the impact of aggregation patterns on the energy levels at the D/A interface has not been fully elucidated. Herein, we focus on ITIC, a widely used acceptor in OSCs, and designed a meta-linked isomer of ITIC (referred to as im-ITIC) to alter molecular symmetry and modify substitution arrangements. Concentration-dependent 1H NMR spectra revealed that im-ITIC shows stronger aggregation behavior in solution. Single-crystal X-ray analysis showed that im-ITIC forms both tail-to-tail (J-aggregation) and face-to-face (H-aggregation) stacking modes, whereas ITIC exclusively forms tail-to-tail stacking. OSCs based on PBDB-T:im-ITIC showed a high VOC value of 1.02 V, which is 0.12 V higher than that of those based on PBDB-T:ITIC. Time-resolved infrared measurements revealed the lifetime of free electrons for the pristine and blend films. The energy levels of the charge transfer state (ECT) for PBDB-T:im-ITIC- and PBDB-T:ITIC OSCs were determined to be 1.57 and 1.39 eV, respectively, correlating with the VOC values. Theoretical calculations indicated that pronounced H-aggregation in im-ITIC increases the ECT compared with J-aggregation, contributing to the improved VOC. This study underscores the critical impact of molecular aggregation patterns on energy alignment and VOC enhancement, offering insights into molecular design for achieving high VOC in OSCs. en-copyright= kn-copyright= en-aut-name=WangKai en-aut-sei=Wang en-aut-mei=Kai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=JinnaiSeihou en-aut-sei=Jinnai en-aut-mei=Seihou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UesakaKaito en-aut-sei=Uesaka en-aut-mei=Kaito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamakataAkira en-aut-sei=Yamakata en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IeYutaka en-aut-sei=Ie en-aut-mei=Yutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=The Institute of Scientific and Industrial Research (SANKEN), The University of Osaka kn-affil= affil-num=2 en-affil=The Institute of Scientific and Industrial Research (SANKEN), The University of Osaka kn-affil= affil-num=3 en-affil=Graduate School of Natural Science & Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Natural Science & Technology, Okayama University kn-affil= affil-num=5 en-affil=The Institute of Scientific and Industrial Research (SANKEN), The University of Osaka kn-affil= END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=26 article-no= start-page=12024 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=2025 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Collective motions in the primary coordination sphere: a critical functional framework for catalytic activity of the oxygen-evolving complex of photosystem II en-subtitle= kn-subtitle= en-abstract= kn-abstract=Photosynthetic water oxidation, vital for dioxygen production and light energy conversion, is catalyzed by the oxygen-evolving complex of photosystem II, where the inorganic Mn4CaO5 cluster acts as the catalytic core. In this study, we investigate the functional significance of collective motions of amino acid side chains within the primary coordination sphere of the Mn cluster, focusing on their role in modulating the energetic demands for catalytic transformations in the S3 state. We applied regularized canonical correlation analysis to quantitatively correlate the three-dimensional arrangement of coordinating atoms with catalytic driving forces computed via density functional theory. Our analysis reveals that distinct collective side chain motions profoundly influence the energetic requirements for structural reconfigurations of the Mn cluster, achieved through expansion and contraction of the ligand cavity while fine-tuning its geometry to stabilize key intermediates. Complementary predictions from a neural network-based machine learning model indicate that the coordination sphere exerts a variable energetic impact on the catalytic transformations of the Mn cluster, depending on the S-state environment. Integrated computational analyses suggest that the extended lifetime of the S3YZ? state, consistently observed after three flash illuminations, may result from slow, progressive protein dynamics that continuously reshape the energy landscape, thereby shifting the equilibrium positions of rapid, reversible chemical processes over time. Overall, our findings demonstrate that collective motions in the primary coordination sphere constitute an active, dynamic framework essential for the efficient execution of multi-electron catalysis under ambient conditions, while simultaneously achieving a high selectivity with irreversible nature required for effective 3O2 evolution. en-copyright= kn-copyright= en-aut-name=IsobeHiroshi en-aut-sei=Isobe en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SuzukiTakayoshi en-aut-sei=Suzuki en-aut-mei=Takayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SugaMichihiro en-aut-sei=Suga en-aut-mei=Michihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ShenJian-Ren en-aut-sei=Shen en-aut-mei=Jian-Ren kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamaguchiKizashi en-aut-sei=Yamaguchi en-aut-mei=Kizashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=4 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=5 en-affil=Center for Quantum Information and Quantum Biology, Osaka University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=1 article-no= start-page=2 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250128 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effect of temperature cycles on the sleep-like state in Hydra vulgaris en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Sleep is a conserved physiological phenomenon across species. It is mainly controlled by two processes: a circadian clock that regulates the timing of sleep and a homeostat that regulates the sleep drive. Even cnidarians, such as Hydra and jellyfish, which lack a brain, display sleep-like states. However, the manner in which environmental cues affect sleep-like states in these organisms remains unknown. In the present study, we investigated the effects of light and temperature cycles on the sleep-like state in Hydra vulgaris.
Results Our findings indicate that Hydra responds to temperature cycles with a difference of up to 5° C, resulting in decreased sleep duration under light conditions and increased sleep duration in dark conditions. Furthermore, our results reveal that Hydra prioritizes temperature changes over light as an environmental cue. Additionally, our body resection experiments show tissue-specific responsiveness in the generation ofthe sleep-like state under different environmental cues. Specifically, the upper body can generate the sleep-like state in response to a single environmental cue. In contrast, the lower body did not respond to 12-h light?dark cycles at a constant temperature.
Conclusions These findings indicate that both light and temperature influence the regulation of the sleep-like state in Hydra. Moreover, these observations highlight the existence of distinct regulatory mechanisms that govern patterns of the sleep-like state in brainless organisms, suggesting the potential involvement of specific regions for responsiveness of environmental cues for regulation of the sleep-like state. en-copyright= kn-copyright= en-aut-name=SatoAya en-aut-sei=Sato en-aut-mei=Aya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SekiguchiManabu en-aut-sei=Sekiguchi en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakadaKoga en-aut-sei=Nakada en-aut-mei=Koga kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YoshiiTaishi en-aut-sei=Yoshii en-aut-mei=Taishi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ItohTaichi Q. en-aut-sei=Itoh en-aut-mei=Taichi Q. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Faculty of Arts and Science, Kyushu University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Systems Life Sciences, Kyushu University kn-affil= affil-num=4 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Faculty of Arts and Science, Kyushu University kn-affil= en-keyword=Hydra kn-keyword=Hydra en-keyword=Sleep kn-keyword=Sleep en-keyword=Temperature kn-keyword=Temperature en-keyword=Environmental cues kn-keyword=Environmental cues END start-ver=1.4 cd-journal=joma no-vol=41 cd-vols= no-issue=7 article-no= start-page=1073 end-page=1082 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250520 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Direct insertion of an ion channel immobilized on a soft agarose gel bead into a lipid bilayer: an optimized method en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this paper, we report the development of a device that improves the conventional artificial lipid bilayer method and can measure channel currents more efficiently. Ion channel proteins are an attractive research target in biophysics, because their functions can be measured at the single-molecule level with high time resolution. In addition, they have attracted attention as targets for drug discovery because of their crucial roles in vivo. Although electrophysiological methods are powerful tools for studying channel proteins, they suffer from low measurement efficiency and require considerable skill. In our previous paper, we reported that by immobilizing channel proteins on agarose gel beads and forming an artificial lipid bilayer on the bead surface, we simultaneously solved two problems that had been hindering the efficiency of the artificial bilayer method: the time-consuming formation of artificial lipid bilayers and the time-consuming incorporation of channels into artificial bilayers. Previous studies have utilized crosslinked hard beads; however, here we show that channel current measurement can be achieved more simply and efficiently using non-crosslinked soft beads. In this study, we detailed the process of immobilizing channel proteins on the surface of non-crosslinked beads through chemical modification, allowing us to measure their channel activity. This method enables current measurements without the need for stringent bead size selection or high negative pressure. en-copyright= kn-copyright= en-aut-name=AsakuraMami en-aut-sei=Asakura en-aut-mei=Mami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WangShuyan en-aut-sei=Wang en-aut-mei=Shuyan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HiranoMinako en-aut-sei=Hirano en-aut-mei=Minako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IdeToru en-aut-sei=Ide en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=Ion channel kn-keyword=Ion channel en-keyword=Artificial lipid bilayer kn-keyword=Artificial lipid bilayer en-keyword=Suction fixation kn-keyword=Suction fixation en-keyword=Soft agarose bead kn-keyword=Soft agarose bead en-keyword=Current recording kn-keyword=Current recording END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250710 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Neurotransmitter and Receptor Mapping in Drosophila Circadian Clock Neurons via T2A-GAL4 Screening en-subtitle= kn-subtitle= en-abstract= kn-abstract=The circadian neuronal network in the brain comprises central pacemaker neurons and associated input and output pathways. These components work together to generate coherent rhythmicity, synchronize with environmental time cues, and convey circadian information to downstream neurons that regulate behaviors such as the sleep/wake cycle. To mediate these functions, neurotransmitters and neuromodulators play essential roles in transmitting and modulating signals between neurons. In Drosophila melanogaster, approximately 240 brain neurons function as clock neurons. Previous studies have identified several neurotransmitters and neuromodulators, including the Pigment-dispersing factor (PDF) neuropeptide, along with their corresponding receptors in clock neurons. However, our understanding of the neurotransmitters and receptors involved in the circadian system remains incomplete. In this study, we conducted a T2A-GAL4-based screening for neurotransmitter and receptor genes expressed in clock neurons. We identified 2 neurotransmitter-related genes and 22 receptor genes. Notably, while previous studies had reported the expression of 6 neuropeptide receptor genes in large ventrolateral neurons (l-LNv), we also found that 14 receptor genes?including those for dopamine, serotonin, and γ-aminobutyric acid?are expressed in l-LNv neurons. These findings suggest that l-LNv neurons serve as key integrative hubs within the circadian network, receiving diverse external signals. en-copyright= kn-copyright= en-aut-name=FukudaAyumi en-aut-sei=Fukuda en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SaitoAika en-aut-sei=Saito en-aut-mei=Aika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YoshiiTaishi en-aut-sei=Yoshii en-aut-mei=Taishi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=clock neurons kn-keyword=clock neurons en-keyword=neurotransmitter kn-keyword=neurotransmitter en-keyword=T2A-GAL4 kn-keyword=T2A-GAL4 en-keyword=immunostaining kn-keyword=immunostaining en-keyword=Drosophila kn-keyword=Drosophila END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue=1 article-no= start-page=32 end-page=35 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250627 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The relationship between sleep disorder and dairy intake in university students of the nursing department in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study was conducted to clarify the relationship between sleep disorders and frequency, or timing of dairy intake with 192 university students in Japan. Pearson’s chi-squared test was carried out to find the relationship between two groups of sleep disorders and the timing of dairy product intake (p = 0.034, df = 4, χ2 = 10.38). The sleep disorder occurred significantly less if participants took a dairy product in the morning (p = 0.004) and significantly more when participants took a dairy product in the afternoon (p = 0.028). The findings showed that consuming dairy products in the morning is effective in treating sleep disorders. en-copyright= kn-copyright= en-aut-name=EdahiroShiho en-aut-sei=Edahiro en-aut-mei=Shiho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakebayashiMaho en-aut-sei=Takebayashi en-aut-mei=Maho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KobayashiYui en-aut-sei=Kobayashi en-aut-mei=Yui kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakahataYoko en-aut-sei=Takahata en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Nursing, Faculty of Medicine, Okayama University kn-affil= affil-num=2 en-affil=Department of Nursing, Faculty of Medicine, Okayama University kn-affil= affil-num=3 en-affil=Department of Nursing, Faculty of Medicine, Okayama University kn-affil= affil-num=4 en-affil=Department of Nursing, Faculty of Medicine, Okayama University kn-affil= en-keyword=sleep disorder kn-keyword=sleep disorder en-keyword=the frequency of dairy products kn-keyword=the frequency of dairy products en-keyword=the timing of dairy products kn-keyword=the timing of dairy products en-keyword=nursing students kn-keyword=nursing students END start-ver=1.4 cd-journal=joma no-vol=32 cd-vols= no-issue=4 article-no= start-page=773 end-page=782 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250508 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Japanese translation of the Functional Assessment of Cancer Therapy-Breast?+?4 (FACT-B?+?4) following international guidelines: a verification of linguistic validity en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background For breast cancer patients, postoperative lymphedema and upper limb movement disorders are serious complications that absolutely reduce their quality of life (QOL). To evaluate this serious complication, we used “Quick Dash” or “FACT-B”, which can assess a patient's physical, social, emotional, and functional health status. To evaluate their breast cancer surgery-related dysfunction correctly, “FACT-B?+?4” was created by adding four questions about “arm swelling'' and “tenderness”. We have translated it into Japanese according to international translation guidelines.
Methods At the beginning, we contacted FACT headquarters that we would like to create a Japanese version of FACT-B?+?4. They formed the FACIT Trans Team (FACIT) following international translation procedures, and then, we began translating according to them. The steps are 1: perform “Forward and Reverse translations” to create a “Preliminary Japanese version”, 2: request the cooperation of 5 breast cancer patients and “conduct a pilot study” and “questionnaire survey”, and 3: amendments and final approval based on pilot study results and clinical perspectives.
Result In Step1, FACIT requested faithful translation of the words, verbs, and nouns from the original text. In Step2, patients reported that they felt uncomfortable with the Japanese version words such as “numb'' and “stiffness'' and felt that it might be difficult to describe their symptoms accurately. In Step3, we readjusted the translation to be more concise and closer to common Japanese language, and performed “Step1” again to ensure that the translation definitely retained the meaning of the original.
Conclusion A Japanese version of FACT has existed until now, but there was no Japanese version of FACT-B?+?4, which adds four additional items to evaluate swelling and pain in the upper limbs. This time, we have created a Japanese version that has been approved by FACT. en-copyright= kn-copyright= en-aut-name=TsukiokiTakahiro en-aut-sei=Tsukioki en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakataNozomu en-aut-sei=Takata en-aut-mei=Nozomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=DennisSaya R. en-aut-sei=Dennis en-aut-mei=Saya R. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TerataKaori en-aut-sei=Terata en-aut-mei=Kaori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SagaraYasuaki en-aut-sei=Sagara en-aut-mei=Yasuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SakaiTakehiko en-aut-sei=Sakai en-aut-mei=Takehiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakayamaShin en-aut-sei=Takayama en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KitagawaDai en-aut-sei=Kitagawa en-aut-mei=Dai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KikawaYuichiro en-aut-sei=Kikawa en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TakahashiYuko en-aut-sei=Takahashi en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=IwataniTsuguo en-aut-sei=Iwatani en-aut-mei=Tsuguo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=HaraFumikata en-aut-sei=Hara en-aut-mei=Fumikata kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=FujisawaTomomi en-aut-sei=Fujisawa en-aut-mei=Tomomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=ShienTadahiko en-aut-sei=Shien en-aut-mei=Tadahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Simpson Querrey Biomedical Research Center, Northwestern University kn-affil= affil-num=3 en-affil=Department of Preventive Medicine Feinberg School of Medicine, Northwestern University kn-affil= affil-num=4 en-affil=Department of Breast and Endocrine Surgery, Akita University Hospital kn-affil= affil-num=5 en-affil=Department of Breast Surgical Oncology, Social Medical Corporation Hakuaikai Sagara Hospital kn-affil= affil-num=6 en-affil=Department of Surgical Oncology, Breast Oncology Center, Cancer Institute Hospital of JFCR kn-affil= affil-num=7 en-affil=Department of Breast Surgery, National Cancer Center Hospital kn-affil= affil-num=8 en-affil=Department of Breast Surgical Oncology, National Center for Global Health and Medicine kn-affil= affil-num=9 en-affil=Department of Breast Surgery, Kansai Medical University Hospital kn-affil= affil-num=10 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Breast Oncology, Aichi Cancer Center Hospital kn-affil= affil-num=13 en-affil=Department of Breast Cancer, Gunma Prefectural Cancer Center kn-affil= affil-num=14 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= en-keyword=Breast cancer kn-keyword=Breast cancer en-keyword=FACT-B kn-keyword=FACT-B en-keyword=FACT-B+4 kn-keyword=FACT-B+4 en-keyword=QOL kn-keyword=QOL END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=236 end-page=244 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230623 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Non Real-Time Data Transmission Performance Analysis of PROFINET for Assuring Data Transmission Quality en-subtitle= kn-subtitle= en-abstract= kn-abstract=The industrial Ethernet PROFINET supports three different data transmission modes: isochronous real-time (IRT), real-time (RT), and non real-time (NRT) transmitting data requiring hard, soft, and no real-time performances, respectively. The data transmission latency in the NRT increased with the amount of data transmission in the IRT, RT, and NRT. Therefore, the quality of data transmission in NRT may degrade as the amount of data transmission in IRT, RT, and NRT increases. In this study, we derived the average data transmission latency in an NRT with data transmission in IRT and RT by applying stochastic processes. This allowed us to maintain the quality of data transmission in the NRT by adjusting the number of devices connected to the network and the number of applications transmitting data in the NRT so that the average latency of data in the NRT does not exceed a certain value. en-copyright= kn-copyright= en-aut-name=NorimatsuTakashi en-aut-sei=Norimatsu en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamauchiToshihiro en-aut-sei=Yamauchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Industrial Ethernet kn-keyword=Industrial Ethernet en-keyword=PROFINET kn-keyword=PROFINET en-keyword=Non Real Time kn-keyword=Non Real Time en-keyword=Real-Time kn-keyword=Real-Time en-keyword=Isochronous Real Time kn-keyword=Isochronous Real Time END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=6 article-no= start-page=e86695 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250624 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Managing Persistent Pupillary Membranes With Surgery or Medication: A Report of Three Cases en-subtitle= kn-subtitle= en-abstract= kn-abstract=The persistent pupillary membrane, as a congenital anomaly, is a remnant of a network of feeding blood vessels for the lens of the eye, called tunica vasculosa lentis. This study reports three patients with persistent pupillary membrane in both eyes who presented in different situations and were managed differently to achieve better vision. The first child (Case 1) who had been seen initially at the age of two years complained of severe photophobia even though he had good visual acuity, and hence, he and his family chose surgical resection of the pupillary membrane in both eyes at the age of six years just before the admission to an elementary school. He did not develop any surgical complications, such as cataract and glaucoma, and maintained the visual acuity in decimals of 1.2 in both eyes at the age of 17 years.
The second child (Case 2), who was seen first at the age of one month, had persistent pupillary membranes in both eyes, together with Peters' anomaly in the left eye. The iris process adhesion to the corneal inner surface was visualized later by optical coherence tomography. She wore full-correction glasses and obtained the visual acuity of 0.7 in the right eye, so she had no problem studying at an elementary school. She used topical 1% atropine once a week in both eyes to maintain pupillary dilation and also used 0.5% timolol and 1% brinzolamide as pressure-lowering eye drops in the left eye with Peters' anomaly.
The third patient (Case 3) with persistent pupillary membranes in both eyes complained of vision problems for the first time at the age of 49 years when she developed cataract. Surgical resection of the pupillary membrane was done in the initial phase of cataract surgery with intraocular lens implantation in both eyes. At surgical resection of the pupillary membrane, a safe and efficient way was to cut the root of the pupillary membrane on the iris surface with scissors, and then the isolated tissues of the pupillary membrane were pulled out with forceps from the side port at the corneal limbus. Pathological examinations of the excised tissues showed blood vessels with red blood cells in the lumen. In such a rare congenital disease as the persistent pupillary membrane, a case-based approach to choose a better option in different conditions from individual to individual is still required to have a better vision in learning at school and in daily working life. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Division of Healthcare Science, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=anterior segment dysgenesis kn-keyword=anterior segment dysgenesis en-keyword=cataract kn-keyword=cataract en-keyword=forceps kn-keyword=forceps en-keyword=optical coherence tomography kn-keyword=optical coherence tomography en-keyword=persistent pupillary membrane kn-keyword=persistent pupillary membrane en-keyword=peters anomaly kn-keyword=peters anomaly en-keyword=resection kn-keyword=resection en-keyword=scissors kn-keyword=scissors en-keyword=vitrectomy cutter kn-keyword=vitrectomy cutter END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=5 article-no= start-page=e83484 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250504 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Detailed Ophthalmic and Pathological Features of Choroidal Metastasis From Breast Cancer: A Case Series of Five Patients en-subtitle= kn-subtitle= en-abstract= kn-abstract=Breast cancer causes choroidal metastases on rare occasions. This study presented the eye manifestations of choroidal metastases from breast cancer and their response to treatments in detail as well as their pathological correlation in five patients. The patients' age at the diagnosis of breast cancer ranged from 24 to 69 years (median: 37 years). The time from the diagnosis of breast cancer to the detection of metastases was concurrent in one patient, two years later in three patients, and six years later in the other patient. The time from the detection of systemic metastases to the detection of choroidal metastases was the same in one patient, while it ranged from one to seven years later in four patients. Choroidal metastases were in the unilateral eye of four patients, whereas they were in both eyes of one patient. Choroidal metastases manifested as one or a few nodular or flat choroidal lesions with serous retinal detachment. As for the treatment of choroidal metastases, enucleation of the right eye was chosen based on the patient's wish as well as the family's wish in the earliest patient when cancer notification was not the norm in Japan. In the other four patients, whole-eye radiation was performed to reduce the choroidal metastatic lesions. As regards the prognosis, which was available in four patients, three patients died within one year from the diagnosis of choroidal metastases, while one patient died one year and eight months later. Regarding the pathology of breast cancer, which was available in four patients, immunostaining of the preserved enucleated eye in the earliest patient revealed that breast cancer cells in the choroidal metastatic lesion were positive for estrogen receptor and negative for progesterone receptor and human epidermal growth factor receptor 2 (HER2). Invasive ductal carcinoma in two patients was positive for estrogen receptor and negative for HER2, while invasive ductal carcinoma in the other patient was triple-negative for estrogen receptor, progesterone receptor, and HER2 with a high Ki-67 index. In conclusion, the prognosis for life was poor in patients with breast cancer who developed choroidal metastases. Choroidal metastatic lesions showed a response to whole-eye radiation to improve the quality of vision at the end of life. Vision-related symptoms should be monitored in the course of chemotherapy for systemic metastases. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShienTadahiko en-aut-sei=Shien en-aut-mei=Tadahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MuraokaAtsushi en-aut-sei=Muraoka en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=DoiharaHiroyoshi en-aut-sei=Doihara en-aut-mei=Hiroyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Division of Healthcare Science, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Surgery, Kagawa Rosai Hospital kn-affil= affil-num=5 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= en-keyword=breast cancer kn-keyword=breast cancer en-keyword=chemotherapy kn-keyword=chemotherapy en-keyword=choroidal metastasis kn-keyword=choroidal metastasis en-keyword=estrogen receptor kn-keyword=estrogen receptor en-keyword=her2 kn-keyword=her2 en-keyword=immunostaining kn-keyword=immunostaining en-keyword=invasive ductal carcinoma kn-keyword=invasive ductal carcinoma en-keyword=ki-67 kn-keyword=ki-67 en-keyword=progesterone receptor kn-keyword=progesterone receptor en-keyword=radiation kn-keyword=radiation END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=12 article-no= start-page=3780 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250617 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of Sampling Frequency on Human Activity Recognition with Machine Learning Aiming at Clinical Applications en-subtitle= kn-subtitle= en-abstract= kn-abstract=Human activity recognition using wearable accelerometer data can be a useful digital biomarker for severity assessment and the diagnosis of diseases, where the relationship between onset and patient activity is crucial. For long-term monitoring in clinical settings, the volume of data collected over time should be minimized to reduce power consumption, computational load, and communication volume. This study aimed to determine the lowest sampling frequency that maintains recognition accuracy for each activity. Thirty healthy participants wore nine-axis accelerometer sensors at five body locations and performed nine activities. Machine-learning-based activity recognition was conducted using data sampled at 100, 50, 25, 20, 10, and 1 Hz. Data from the non-dominant wrist and chest, which have previously shown high recognition accuracy, were used. Reducing the sampling frequency to 10 Hz did not significantly affect the recognition accuracy for either location. However, lowering the frequency to 1 Hz decreases the accuracy of many activities, particularly brushing teeth. Using data with a 10 Hz sampling frequency can maintain recognition accuracy while decreasing data volume, enabling long-term patient monitoring and device miniaturization for clinical applications. en-copyright= kn-copyright= en-aut-name=YamaneTakahiro en-aut-sei=Yamane en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KimuraMoeka en-aut-sei=Kimura en-aut-mei=Moeka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MoritaMizuki en-aut-sei=Morita en-aut-mei=Mizuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Biomedical Informatics, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Health Sciences, Okayama University Medical School kn-affil= affil-num=3 en-affil=Department of Biomedical Informatics, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=wearable devices kn-keyword=wearable devices en-keyword=machine learning kn-keyword=machine learning en-keyword=human activity recognition kn-keyword=human activity recognition en-keyword=sampling frequency kn-keyword=sampling frequency en-keyword=digital health kn-keyword=digital health en-keyword=digital biomarkers kn-keyword=digital biomarkers END start-ver=1.4 cd-journal=joma no-vol=121 cd-vols= no-issue=2 article-no= start-page=232 end-page=243 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241216 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Outcomes of allogeneic SCT versus tisagenlecleucel in patients with R/R LBCL and poor prognostic factors en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study investigated the efficacy of tisagenlecleucel (tisa-cel) and allogeneic hematopoietic stem cell transplantation (allo-SCT) for patients with relapsed and/or refractory (r/r) large B-cell lymphoma (LBCL) with poor prognostic factors, defined as performance status (PS)???2, multiple extranodal lesions (EN), chemorefractory disease, or higher lactate dehydrogenase (LDH). Overall, the allo-SCT group demonstrated worse progression-free survival (PFS), higher non-relapse mortality, and a similar relapse/progression rate. Notably, the tisa-cel group showed better PFS than the allo-SCT group among patients with chemorefractory disease (3.2 vs. 2.0 months, p?=?0.092) or higher LDH (4.0 vs. 2.0 months, p =?0.018), whereas PFS in the two cellular therapy groups was similar among those with PS???2 or multiple EN. Survival time after relapse post-cellular therapy in patients with poor prognostic factors was 1.6 with allo-SCT and 4.6 months with tisa-cel. These findings were confirmed in a propensity score matching cohort. In conclusion, tisa-cel resulted in better survival than allo-SCT in patients with poor prognostic factors. However, patients who relapsed post-cellular therapy had dismal outcomes regardless of therapy. Further strategies are warranted to improve outcomes in these patients. en-copyright= kn-copyright= en-aut-name=HayashinoKenta en-aut-sei=Hayashino en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TeraoToshiki en-aut-sei=Terao en-aut-mei=Toshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishimoriHisakazu en-aut-sei=Nishimori en-aut-mei=Hisakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KitamuraWataru en-aut-sei=Kitamura en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KobayashiHiroki en-aut-sei=Kobayashi en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KamoiChihiro en-aut-sei=Kamoi en-aut-mei=Chihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SeikeKeisuke en-aut-sei=Seike en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FujiwaraHideaki en-aut-sei=Fujiwara en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=AsadaNoboru en-aut-sei=Asada en-aut-mei=Noboru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=EnnishiDaisuke en-aut-sei=Ennishi en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=FujiiKeiko en-aut-sei=Fujii en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=FujiiNobuharu en-aut-sei=Fujii en-aut-mei=Nobuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MatsuokaKen-ichi en-aut-sei=Matsuoka en-aut-mei=Ken-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Hematology and Oncology, Okayama University Hospital, Okayama University kn-affil= affil-num=2 en-affil=Department of Hematology and Oncology, Okayama University Hospital, Okayama University kn-affil= affil-num=3 en-affil=Department of Hematology and Oncology, Okayama University Hospital, Okayama University kn-affil= affil-num=4 en-affil=Department of Hematology and Oncology, Okayama University Hospital, Okayama University kn-affil= affil-num=5 en-affil=Department of Hematology and Oncology, Okayama University Hospital, Okayama University kn-affil= affil-num=6 en-affil=Department of Hematology and Oncology, Okayama University Hospital, Okayama University kn-affil= affil-num=7 en-affil=Department of Hematology and Oncology, Okayama University Hospital, Okayama University kn-affil= affil-num=8 en-affil=Department of Hematology and Oncology, Okayama University Hospital, Okayama University kn-affil= affil-num=9 en-affil=Department of Hematology and Oncology, Okayama University Hospital, Okayama University kn-affil= affil-num=10 en-affil=Department of Hematology and Oncology, Okayama University Hospital, Okayama University kn-affil= affil-num=11 en-affil=Department of Hematology and Oncology, Okayama University Hospital, Okayama University kn-affil= affil-num=12 en-affil=Department of Hematology and Oncology, Okayama University Hospital, Okayama University kn-affil= affil-num=13 en-affil=Department of Hematology and Oncology, Okayama University Hospital, Okayama University kn-affil= affil-num=14 en-affil=Department of Hematology and Oncology, Okayama University Hospital, Okayama University kn-affil= en-keyword=Large B-cell lymphoma kn-keyword=Large B-cell lymphoma en-keyword=Allogeneic hematopoietic stem cell transplantation kn-keyword=Allogeneic hematopoietic stem cell transplantation en-keyword=CAR-T cell therapy kn-keyword=CAR-T cell therapy en-keyword=Tisagenlecleucel kn-keyword=Tisagenlecleucel en-keyword=Poor prognostic factors kn-keyword=Poor prognostic factors END start-ver=1.4 cd-journal=joma no-vol=31 cd-vols= no-issue=6 article-no= start-page=388.e1 end-page=388.e14 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202506 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinical effects of granulocyte colony-stimulating factor administration and the timing of its initiation on allogeneic hematopoietic cell transplantation outcomes for myelodysplastic syndrome en-subtitle= kn-subtitle= en-abstract= kn-abstract=Granulocyte colony-stimulating factor (G-CSF) accelerates neutrophil recovery after allogeneic hematopoietic cell transplantation (HCT). However, the optimal use of G-CSF and the timing of its initiation after allogeneic HCT for myelodysplastic syndrome (MDS) according to graft type have not been determined. This retrospective study aimed to investigate the effects of using G-CSF administration and the timing of its initiation on transplant outcomes in adult patients with MDS undergoing allogeneic HCT. Using Japanese registry data, we retrospectively investigated the effects of G-CSF administration and the timing of its initiation on transplant outcomes among 4140 adults with MDS after bone marrow transplantation (BMT), peripheral blood stem cell transplantation (PBSCT), or single-unit cord blood transplantation (CBT) between 2013 and 2022. Multivariate analysis showed that early (days 0 to 4) and late (days 5 to 10) G-CSF administration significantly accelerated neutrophil recovery compared with no G-CSF administration following BMT, PBSCT, and CBT, but there was no benefit of early G-CSF initiation for early neutrophilic recovery regardless of graft type. Late G-CSF initiation was significantly associated with a higher risk of overall chronic GVHD following PBSCT (hazard ratio [HR], 1.63; 95% confidence interval [CI], 1.18 to 2.24; P = .002) and CBT (HR, 2.09; 95% CI, 1.21 to 3.60; P = .007) compared with no G-CSF administration. Late G-CSF initiation significantly improved OS compared with no G-CSF administration only following PBSCT (HR, 0.74; 95% CI, 0.58 to 0.94; P = .015). However, G-CSF administration and the timing of its initiation did not affect acute GVHD, relapse, or non-relapse mortality, irrespective of graft type. These results suggest that G-CSF administration significantly accelerated neutrophil recovery after BMT, PBSCT, and CBT, but increased risk of overall chronic GVHD after PBSCT and CBT. However, the effect of early and late G-CSF initiation on transplant outcomes needs further study in adult patients with MDS. en-copyright= kn-copyright= en-aut-name=KonumaTakaaki en-aut-sei=Konuma

survivors of glioblastoma: A proposal based on SEER registry data en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Glioblastomas (GBMs) are central nervous system tumors with a poor prognosis and limited treatment options. Although small subsets of GBM patients survive longer than 3 years, there is little evidence regarding the prognostic factors of GBM. Therefore, we conducted a thorough characterization of GBM in the United States.
Methods: We queried the Surveillance, Epidemiology, and End Results database between 2000 and 2021 to extract age-adjusted incidence rates (AAIRs), age-adjusted mortality rates (AAMRs), and survival data for GBM. We compared trends in AAIR, AAMR, and survival time across age groups 0?14, 15?39, 40?69, and 70+ years. Also, we employed the Fine?Gray competing risk model among short-term survivors (STSs), defined as those with a survival time of 6 months or less, and long-term survivors (LTSs), defined as those with a survival time of 3 years or more.
Results: This study included 60 615 incident GBM cases, 54 998 GBM-specific deaths, and 47 207 GBM patients with available survival time between 2000 and 2021. The mortality-to-incidence ratio was constant among STSs, whereas it increased with age among LTSs. Higher age and male sex were significantly associated with GBM-specific death among LTSs, whereas non-Hispanic White and less intensive treatments were associated with GBM-specific deaths among STSs. Interestingly, higher age was significantly associated with other causes of death among STSs.
Conclusions: STSs partially consist of populations who died from causes other than GBM. It is important to include only GBM-specific deaths in STS groups to conduct reproducible research comparing STSs and LTSs. en-copyright= kn-copyright= en-aut-name=TomitaYusuke en-aut-sei=Tomita en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OtaniYoshihiro en-aut-sei=Otani en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OmaeRyo en-aut-sei=Omae en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MizutaRyo en-aut-sei=Mizuta en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IshidaJoji en-aut-sei=Ishida en-aut-mei=Joji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HirotsuneNobuyuki en-aut-sei=Hirotsune en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TanakaShota en-aut-sei=Tanaka en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Medical School kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Neurosurgery and Neuroendovascular Surgery, Hiroshima City Hiroshima Citizens Hospital kn-affil= affil-num=7 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=glioblastoma kn-keyword=glioblastoma en-keyword=long-term survivor kn-keyword=long-term survivor en-keyword=SEER kn-keyword=SEER en-keyword=short-term survivor kn-keyword=short-term survivor en-keyword=United States kn-keyword=United States END start-ver=1.4 cd-journal=joma no-vol=295 cd-vols= no-issue= article-no= start-page=128303 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Using a microfluidic paper-based analytical device and solid-phase extraction to determine phosphate concentration en-subtitle= kn-subtitle= en-abstract= kn-abstract=Phosphate is an essential nutrient, but in high concentrations it contributes to water pollution. Traditional methods for phosphate measurement, such as absorption spectrophotometry and ion chromatography, require expensive equipment and skilled operators. This study introduces a microfluidic paper-based analytical device (μPAD) that is designed to accomplish field-based, low-concentration phosphate measurements. This μPAD utilizes colorimetric detection based on the molybdenum blue method. Herein, we describe how the conditions were optimized in terms of design and sensitivity by adjusting reagent concentrations, paper thickness, and the time frames for sample introduction, and reaction. The operation consists of simply dipping the μPAD into a sample, capturing images in a home-made photo studio box, and processing the images with ImageJ software to measure RGB intensity. An additional preconcentration step involves solid-phase extraction with an anion exchange resin that achieves a 10-fold enrichment, which enables detection that ranges from 0.05 to 1 mg L?1 with a detection limit of 0.089 mg L?1 and a quantification limit of 0.269 mg L?1. The replicated measurements showed good reproducibility both intraday and interday (five different days) as 4.7 % and 3.0 % of relative standard deviations, respectively. After storage in a refrigerator for as long as 26 days, this μPAD delivered stable and accurate results for real-world samples of natural water, soil, and toothpaste. The results produced using this system correlate well with those produced via spectrophotometry. This μPAD-based method is a cost-effective, portable, rapid, and simple approach that allows relatively unskilled operators to monitor phosphate concentrations in field applications. en-copyright= kn-copyright= en-aut-name=DanchanaKaewta en-aut-sei=Danchana en-aut-mei=Kaewta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NambaHaruka en-aut-sei=Namba en-aut-mei=Haruka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanetaTakashi en-aut-sei=Kaneta en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Chemistry, Okayama University kn-affil= affil-num=2 en-affil=Department of Chemistry, Okayama University kn-affil= affil-num=3 en-affil=Department of Chemistry, Okayama University kn-affil= en-keyword=Phosphate kn-keyword=Phosphate en-keyword=Microfluidic paper-based analytical device kn-keyword=Microfluidic paper-based analytical device en-keyword=Solid-phase extraction kn-keyword=Solid-phase extraction en-keyword=Anion exchanger kn-keyword=Anion exchanger en-keyword=Molybdenum blue method kn-keyword=Molybdenum blue method END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250519 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Novel method of leukocytapheresis using a highly concentrated sodium citrate solution alternative to acid citrate dextrose solution A en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Large-volume leukocytapheresis is time consuming. The upper limit of the inlet flow rate is determined by the inlet: anticoagulant (AC) ratio and can be changed by combining the AC with heparin. Here, we devised a protocol to increase the AC ratio using a highly concentrated sodium citrate solution without heparin.
Study Design and Methods: We collected data from 40 consecutive apheresis procedures performed using the Spectra Optia system on 40 donors for allogeneic peripheral blood stem cells between June 2022 and June 2023. We used AC containing 2.2% sodium citrate (normal concentrated sodium citrate [NSC]) and 5.32% sodium citrate (highly concentrated sodium citrate [HSC]). The AC ratios were set to 12:1 and 24:1 for the NSC and HSC, respectively.
Results: The processed volume was not different; the maximum inlet flow rate increased, the total processing time was reduced, the AC solution used was reduced, and the product volume was reduced in the HSC group, compared to the NSC group. Although the CD34+ cell CE2 was reduced in the HSC group, no difference was observed in the number of collected CD34+ cells. The incidences of citrate-related reactions were similar.
Discussion: We propose a novel leukocytapheresis method using HSC that shortens the procedure time and reduces the amount of AC solution used compared to the conventional method en-copyright= kn-copyright= en-aut-name=AbeMasaya en-aut-sei=Abe en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiiKeiko en-aut-sei=Fujii en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KitamuraWataru en-aut-sei=Kitamura en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IkeuchiKazuhiro en-aut-sei=Ikeuchi en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FukumiTakuya en-aut-sei=Fukumi en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WashioKana en-aut-sei=Washio en-aut-mei=Kana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=FujiiNobuharu en-aut-sei=Fujii en-aut-mei=Nobuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Division of Transfusion and Cell Therapy, Okayama University Hospital kn-affil= affil-num=2 en-affil=Division of Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=3 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=4 en-affil=Division of Transfusion and Cell Therapy, Okayama University Hospital kn-affil= affil-num=5 en-affil=Division of Transfusion and Cell Therapy, Okayama University Hospital kn-affil= affil-num=6 en-affil=Division of Transfusion and Cell Therapy, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Pediatric Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Division of Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Division of Transfusion and Cell Therapy, Okayama University Hospital kn-affil= en-keyword=anticoagulant kn-keyword=anticoagulant en-keyword=apheresis kn-keyword=apheresis en-keyword=high sodium citrate concentration kn-keyword=high sodium citrate concentration en-keyword=Spectra Optia kn-keyword=Spectra Optia END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250220 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Supplement-induced acute kidney injury reproduced in kidney organoids en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Acute kidney injury associated with the consumption of Beni-koji CholesteHelp supplements, which contain red yeast rice (Beni-Koji), has become a significant public health concern in Japan. While renal biopsy findings from several case reports have suggested tubular damage, no definitive causal relationship has been established, and the underlying mechanisms of kidney injury remain poorly understood. The complexity of identifying toxic substances in supplements containing various bioactive compounds makes conventional investigative approaches both time-consuming and challenging. This highlights an urgent need to establish a reliable platform for assessing organ-specific toxicity in such supplements. In this study, we utilized a kidney organoid model derived from adult rat kidney stem cells (KS cells) to assess the potential tubular toxicity of these supplements. Methods: KS cell clusters were cultured in three-dimensional system supplemented with growth factors to promote kidney organoids. The organoids were subsequently exposed to Beni-koji CholesteHelp supplements or cisplatin, followed by histological and molecular analyses to evaluate structural impacts. Results: Established organoids had the kidney-like structures including tubular-like structures and glomerulus-like structures at the tips of multiple tubules. Treatment with Beni-koji CholesteHelp supplements induced significant tubular damage in the organoids, characterized by epithelial cell thinning, structural disruption, and increase in cleaved-caspase 3-positive apoptotic tubular cells, similar to the organoids treated with cisplatin. Conclusion: These findings provide the first evidence suggesting that certain toxicants in specific batches of Beni-koji CholesteHelp supplements cause direct renal tubular injury. This KS cell-based organoid system represents a cost-effective, reproducible, and technically simple platform for nephrotoxicity screening. en-copyright= kn-copyright= en-aut-name=NakanohHiroyuki en-aut-sei=Nakanoh en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsujiKenji en-aut-sei=Tsuji en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FukushimaKazuhiko en-aut-sei=Fukushima en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HaraguchiSoichiro en-aut-sei=Haraguchi en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KitamuraShinji en-aut-sei=Kitamura en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Acute kidney injury kn-keyword=Acute kidney injury en-keyword=Drug-induced nephrotoxicity kn-keyword=Drug-induced nephrotoxicity en-keyword=Kidney organoid kn-keyword=Kidney organoid en-keyword=Kidney stem cell kn-keyword=Kidney stem cell END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250430 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=High-Resolution HPLC for Separating Peptide-Oligonucleotide Conjugates en-subtitle= kn-subtitle= en-abstract= kn-abstract=Peptide-oligonucleotide conjugates (POCs) are chimeric molecules that combine the specificity of oligonucleotides with the functionality of peptides, improving the delivery and therapeutic potential of nucleic acid-based drugs. However, the analysis of POCs, particularly those containing arginine-rich sequences, poses major challenges because of aggregation caused by electrostatic interactions. In this study, we developed an optimized high-performance liquid chromatography (HPLC) method for analyzing POCs. Using a conjugate of DNA and nona-arginine as a model compound, we systematically investigated the effects of various analytical parameters, including column type, column temperature, mobile-phase composition, and pH. A column packed with C18 resin with wide pores combined with butylammonium acetate as the ion-pairing reagent and an optimal column temperature of 80 degrees C provided superior peak resolution and sensitivity. The optimized conditions gave clear separation of POCs from unlinked oligonucleotides and enabled the detection of nucleic acid fragments lacking an alkyne moiety as a linkage part, which is critical for quality control. Our HPLC method is robust and reproducible and substantially reduces the complexity, time, and cost associated with the POC analysis. The method may improve the efficiency of quality control in the production of POCs, thereby supporting their development as promising therapeutic agents for clinical applications. en-copyright= kn-copyright= en-aut-name=NaganumaMiyako en-aut-sei=Naganuma en-aut-mei=Miyako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsujiGenichiro en-aut-sei=Tsuji en-aut-mei=Genichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AmiyaMisato en-aut-sei=Amiya en-aut-mei=Misato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HiraiReira en-aut-sei=Hirai en-aut-mei=Reira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HiguchiYuki en-aut-sei=Higuchi en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HataNaoko en-aut-sei=Hata en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NozawaSaoko en-aut-sei=Nozawa en-aut-mei=Saoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=WatanabeDaishi en-aut-sei=Watanabe en-aut-mei=Daishi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakajimaTaeko en-aut-sei=Nakajima en-aut-mei=Taeko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=DemizuYosuke en-aut-sei=Demizu en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Division of Organic Chemistry, National Institute of Health Sciences kn-affil= affil-num=2 en-affil=Division of Organic Chemistry, National Institute of Health Sciences kn-affil= affil-num=3 en-affil=YMC CO., LTD. kn-affil= affil-num=4 en-affil=YMC CO., LTD. kn-affil= affil-num=5 en-affil=YMC CO., LTD. kn-affil= affil-num=6 en-affil=YMC CO., LTD. kn-affil= affil-num=7 en-affil=YMC CO., LTD. kn-affil= affil-num=8 en-affil=Division of Organic Chemistry, National Institute of Health Sciences kn-affil= affil-num=9 en-affil=YMC CO., LTD. kn-affil= affil-num=10 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Division of Pharmaceutical Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=14323 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250424 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Lymphatic flow dynamics under exercise load assessed with thoracic duct ultrasonography en-subtitle= kn-subtitle= en-abstract= kn-abstract=The thoracic duct (TD) is the largest lymphatic vessel proximal to the venous system. It undergoes morphological changes in response to lymph flow from the periphery, with automatic contraction controlling the dynamics to propel lymph toward the venous system. Recent advancements in ultrasonography have facilitated non-invasive observations of the TD’s terminal, including its valve and wall motions. Observations of TD movements allow predictions of lymphatic flow dynamics. However, no studies have yet documented the changes in the TD under exercise-induced lymph flow enhancement in humans. Here, using 18-MHz high-frequency ultrasonography, we demonstrate for the first time that the TD diameter significantly expands under exercise load. This study analyzed 20 participants; the maximum TD diameters at rest and post-exercise were 2.69?±?1.06 mm and 3.41?±?1.32 mm, respectively (p?=?0.00000056). While various methods exist for observing the TD, our approach?dynamically monitoring the TD diameter using sonography in real time and correlating it with lymphatic flow dynamics?offers a novel contribution. en-copyright= kn-copyright= en-aut-name=ShinaokaAkira en-aut-sei=Shinaoka en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KimataYoshihiro en-aut-sei=Kimata en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Lymphatics and Edematology, Dentistry and Pharmaceutical Science, Okayama University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Plastic and Reconstructive surgery, Dentistry and Pharmaceutical Science, Okayama University Graduate School of Medicine kn-affil= en-keyword=Lymphedema kn-keyword=Lymphedema en-keyword=Lymphatic function kn-keyword=Lymphatic function en-keyword=Lymph flow kn-keyword=Lymph flow en-keyword=Chylothorax kn-keyword=Chylothorax en-keyword=Chylous ascites,lymph velocity kn-keyword=Chylous ascites,lymph velocity END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=4 article-no= start-page=e9631 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250422 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Case of a Metal Foreign Object Remaining in the Maxillary Bone for an Extended Period: A Case Report en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report a rare case in which a metallic foreign body remained undetected in a patient's maxilla for nearly 40 years after a childhood bicycle accident. Despite the accident, the implant remained in place without causing infection due to the lack of imaging studies at the time. The metal was accidentally discovered during a routine dental imaging examination 40 years later and subsequently surgically removed. This case highlights the importance of comprehensive imaging and the dangers of overlooking foreign bodies, especially in the vulnerable head and neck region. The patient, 53 years old at the time of discovery, presented to the dentist due to discomfort in the palate and nasal cavity. During this visit, radiographs were taken and a foreign body was discovered. Surgical removal of the foreign body revealed significant corrosion and surrounding granulation tissue indicative of foreign body granuloma. Elemental analysis of the foreign body confirmed that it was an iron-based metal, unlike biocompatible materials such as titanium. These findings reinforce the need for close post-trauma evaluation and follow-up, especially in cases of pediatric trauma, to avoid the possibility of long-term complications arising from unnoticed foreign bodies in anatomically significant areas. en-copyright= kn-copyright= en-aut-name=KadoyaKoichi en-aut-sei=Kadoya en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KunisadaYuki en-aut-sei=Kunisada en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ObataKyoichi en-aut-sei=Obata en-aut-mei=Kyoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakakuraHiroaki en-aut-sei=Takakura en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OgawaTatsuo en-aut-sei=Ogawa en-aut-mei=Tatsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IbaragiSoichiro en-aut-sei=Ibaragi en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Oral and Maxillofacial Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Oral and Maxillofacial Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Oral and Maxillofacial Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Oral and Maxillofacial Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Oral and Maxillofacial Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Oral and Maxillofacial Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=case report kn-keyword=case report en-keyword=dentistry kn-keyword=dentistry en-keyword=foreign body kn-keyword=foreign body en-keyword=oral cavity kn-keyword=oral cavity en-keyword=trauma kn-keyword=trauma END start-ver=1.4 cd-journal=joma no-vol=23 cd-vols= no-issue=1 article-no= start-page=36 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250416 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Anticoagulant effects of edoxaban in cancer and noncancer patients with venous thromboembolism en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Edoxaban, a direct oral anticoagulant (DOAC), is a first-line treatment for venous thromboembolism (VTE) and the suppression of VTE recurrence. In patients with cancer, however, recurrent VTE after DOAC treatment may be more common than in noncancer patients. To evaluate our hypothesis that the anticoagulation effect of edoxaban is lower in VTE patients with cancer than in noncancer patients.
Methods This study was a prospective, multicenter, observational study including patients treated with edoxaban for VTE in Japan. The primary outcome was the difference in the prothrombin time (PT), activated partial thromboplastin time (APTT), and D-dimer level at 5 h after initial edoxaban administration between the cancer and noncancer groups. An additional outcome was the longitudinal change in PT and APTT from 5 h to overnight after edoxaban administration. The incidence of adverse events was further investigated.
Results PT and APTT at 5 h after initial edoxaban administration were not significantly different between the cancer (n = 84) and noncancer groups (n = 138) (e.g., log-transformed APTT 3.55 vs. 3.55, p = 0.45). However, D-dimer in the cancer groups was significantly greater than that in the noncancer groups (log-transformed 1.83 vs. 1.79, p = 0.009). PT and APTT significantly decreased from 5 h to overnight after edoxaban, but a similar pattern was observed in each group. All adverse events after edoxaban administration were also similar between patients with cancer and noncancer.
Conclusion PT and APTT after edoxaban administration were similar between VTE patients with cancer and noncancer groups, suggesting that edoxaban has anticoagulation effects on cancer-associated VTE similar to those of noncancer patients.

en-abstract= kn-abstract=Background: Gastric cancer (GC) in younger patients often exhibits aggressive behavior and a poorer prognosis than that in older patients. Although the clinical differences may stem from oncogenic gene variations, it is unclear whether genetic differences exist between these groups. This study compared the genetic profiles of early- and late-onset GC and evaluated their impact on treatment outcomes.
Methods: We analyzed genetic data from 1284 patients with GC in the Japanese nationwide Center for Cancer Genomics and Advanced Therapeutics (C-CAT) database, comparing early-onset (<= 39 years; n = 143) and late-onset (>= 65 years; n = 1141) groups. The influence of TP53 mutations on the time to treatment failure (TTF) with platinum-based chemotherapy and the sensitivity of cancer cells with different TP53 mutation sites to oxaliplatin were assessed in vitro.
Results: Early- and late-onset GC showed distinct genetic profiles, with fewer neoantigen-associated genetic changes observed in early-onset cases. In particular, TP53 has distinct mutation sites; R175H and R273 mutations are more frequent in early- and late-onset GC, respectively. The R175H mutation showed higher sensitivity to oxaliplatin in vitro, consistent with the longer TTF in early-onset patients (17.3 vs. 7.0 months, p = 0.013) when focusing on the patients with TP53 mutations.
Conclusion: Genomic differences, particularly in TP53 mutation sites, between early- and late-onset GC support the need for age-specific treatment strategies. en-copyright= kn-copyright= en-aut-name=KamioTomohiro en-aut-sei=Kamio en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KonoYoshiyasu en-aut-sei=Kono en-aut-mei=Yoshiyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HirosunaKensuke en-aut-sei=Hirosuna en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OzatoToshiki en-aut-sei=Ozato en-aut-mei=Toshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamamotoHideki en-aut-sei=Yamamoto en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HirasawaAkira en-aut-sei=Hirasawa en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=EnnishiDaisuke en-aut-sei=Ennishi en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TomidaShuta en-aut-sei=Tomida en-aut-mei=Shuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Regenerative Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Clinical Genomic Medicine, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Clinical Genomic Medicine, Okayama University Hospital kn-affil= affil-num=7 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=8 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=9 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Gastroenterology and Hepatology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=comprehensive genomic profiling kn-keyword=comprehensive genomic profiling en-keyword=early-onset gastric cancer kn-keyword=early-onset gastric cancer en-keyword=oxaliplatin kn-keyword=oxaliplatin en-keyword=TP53 kn-keyword=TP53 END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=2 article-no= start-page=93 end-page=100 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202504 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Lower Work Engagement Is Associated with Insomnia, Psychological Distress, and Neck Pain among Junior and Senior High School Teachers in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=School teachers are subject to both physical and mental health problems. We examined cross-sectional relationships between work engagement and major health outcomes among junior and senior high school teachers in Japan via a nationwide survey in 2019-2020. A total of 3,160 respondents were included in the analyses (19.9% response rate). Work engagement was assessed with the Utrecht Work Engagement Scale-9 (UWES-9), and we thus divided the teachers into quartiles according to their UWES-9 scores. Based on validated questionnaires, we assessed insomnia, psychological distress, and neck pain as health outcomes. A binomial logistic regression adjusted for age, gender, school type, teacher’s roles, involvement in club activities, division of duties, employment status, and whether they lived with family demonstrated that the teachers with lower UWES-9 scores had higher burdens of insomnia, psychological distress, and neck pain (odds ratios [95% confidence intervals] in 4th vs. 1st quartile, 2.92 (2.34-3.65), 3.70 (2.81-4.88), and 2.12 (1.68-2.68), respectively; all trend p<0.001). There were no significant differences in these associations between full-time and part-time teachers. Our findings indicate that low work engagement may contribute to physical and mental health issues among junior and senior high school teachers, thus providing insights for preventing health problems in this profession. en-copyright= kn-copyright= en-aut-name=TsuchieRina en-aut-sei=Tsuchie en-aut-mei=Rina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FukudaMari en-aut-sei=Fukuda en-aut-mei=Mari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsumuraHideki en-aut-sei=Tsumura en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KinutaMinako en-aut-sei=Kinuta en-aut-mei=Minako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HisamatsuTakashi en-aut-sei=Hisamatsu en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KandaHideyuki en-aut-sei=Kanda en-aut-mei=Hideyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Psychology, Graduate School of Technology, Industrial and Social Sciences, Tokushima University kn-affil= affil-num=4 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=work engagement kn-keyword=work engagement en-keyword=school teachers kn-keyword=school teachers en-keyword=insomnia kn-keyword=insomnia en-keyword=psychological distress kn-keyword=psychological distress en-keyword=neck pain kn-keyword=neck pain END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=2 article-no= start-page=65 end-page=73 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202504 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association between the Pretreatment Body Mass Index and Anamorelin’s Efficacy in Patients with Cancer Cachexia: A Retrospective Cohort Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Anamorelin (ANAM) is used to treat cancer-associated cachexia, a syndrome involving muscle loss and anorexia. The timing of the initiation of ANAM treatment is crucial to its efficacy. Although the body mass index (BMI) is a diagnostic criterion for cancer cachexia, no studies have explored its association with ANAM efficacy. We conducted a single-center, retrospective cohort study to investigate the association between the pre-treatment BMI and ANAM efficacy in patients with cancer-associated cachexia (n=47). The ANAM treatment was considered effective if the patient’s appetite improved within 30 days of treatment initiation. We calculated a BMI cutoff value (19.5 kg/m2) and used it to divide the patients into high- and low-BMI groups. Their background, clinical laboratory values, cancer types, and treatment lines were investigated. Twenty (42.6%) had a high BMI (? 19.5 kg/m2) and 27 (57.4%) had a low BMI (< 19.5 kg/m2). High BMI was significantly associated with ANAM effectiveness (odds ratio 7.86, 95% confidence interval 1.99-31.00, p=0.003). Together these results indicate that it is beneficial to initiate ANAM treatment before a patient’s BMI drops below 19.5 kg/m2. Our findings will help advance cancer cachexia treatment and serve as a reference for clinicians to predict ANAM’s efficacy. en-copyright= kn-copyright= en-aut-name=MakiMasatoshi en-aut-sei=Maki en-aut-mei=Masatoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakadaRyo en-aut-sei=Takada en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IshigoTomoyuki en-aut-sei=Ishigo en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujiwaraMiki en-aut-sei=Fujiwara en-aut-mei=Miki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakahashiYoko en-aut-sei=Takahashi en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OtsukaShinya en-aut-sei=Otsuka en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TamuraKoji en-aut-sei=Tamura en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HamaokaTerutaka en-aut-sei=Hamaoka en-aut-mei=Terutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Hospital Pharmacy, NHO Fukuyama Medical Center kn-affil= affil-num=2 en-affil=Department of Hospital Pharmacy, NHO Fukuyama Medical Center kn-affil= affil-num=3 en-affil=Department of Pharmacy, Sapporo Medical University Hospital kn-affil= affil-num=4 en-affil=Department of Hospital Pharmacy, NHO Fukuyama Medical Center kn-affil= affil-num=5 en-affil=Department of Hospital Pharmacy, NHO Fukuyama Medical Center kn-affil= affil-num=6 en-affil=Department of Surgery, NHO Fukuyama Medical Center kn-affil= affil-num=7 en-affil=Department of Hospital Pharmacy, NHO Fukuyama Medical Center kn-affil= affil-num=8 en-affil=Department of Hospital Pharmacy, NHO Fukuyama Medical Center kn-affil= en-keyword=anamorelin kn-keyword=anamorelin en-keyword=cancer-associated cachexia kn-keyword=cancer-associated cachexia en-keyword=body mass index kn-keyword=body mass index en-keyword=albumin kn-keyword=albumin en-keyword=efficacy rate kn-keyword=efficacy rate END start-ver=1.4 cd-journal=joma no-vol=23 cd-vols= no-issue=1 article-no= start-page=124 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250407 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Surgical protocol of robotic liver resection using a two-surgeon technique (TAKUMI-3): a technical note and initial outcomes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Internationally, evidence supporting robotic liver resection (RLR) has gradually increased in recent years. However, a standardized protocol for RLR remains lacking. This study describes a surgical protocol and the initial outcomes of RLR in a high-volume center for robotic hepatopancreatobiliary surgery in Japan.
Methods Patients were placed in the reverse Trendelenburg position, with a supine position for anterolateral tumors and left lateral position for posterosuperior tumors. Our standard RLR protocol involved a two-surgeon technique. Liver parenchymal transection was performed by an assistant using the clamp crush technique with a console, with or without a laparoscopic Cavitron ultrasonic surgical aspirator (CUSA). Surgical techniques, including the tips, tricks, and pitfalls of RLR, are also demonstrated.
Results We performed 113 RLR at our institution for common primary diseases, including hepatocellular carcinoma (n = 52, 46.0%) and metastatic tumors (n = 48, 42.5%) between July 2022 and December 2024. The median operative time and estimated blood loss were 156 min (interquartile range [IQR], 121-209 min) and 20 mL (IQR, 0-100 mL), respectively. During liver parenchymal transection, a laparoscopic CUSA was used in 59 patients (52.2%), and a water-jet scalpel was used in 12 patients (10.6%). The incidence of mortality, major complications, and bile leakage was 0%, 6.2%, and 2.7%, respectively. The median hospital stay was 7 days (IQR, 6-9 days).
Conclusions We successfully introduced an RLR program using the two-surgeon technique. Safe implementation of RLR can be achieved upon completion of the training program and thorough understanding of the surgical protocols. en-copyright= kn-copyright= en-aut-name=TakagiKosei en-aut-sei=Takagi en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiTomokazu en-aut-sei=Fuji en-aut-mei=Tomokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YasuiKazuya en-aut-sei=Yasui en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UmedaYuzo en-aut-sei=Umeda en-aut-mei=Yuzo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamadaMotohiko en-aut-sei=Yamada en-aut-mei=Motohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NishiyamaTakeyoshi en-aut-sei=Nishiyama en-aut-mei=Takeyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NagaiYasuo en-aut-sei=Nagai en-aut-mei=Yasuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KanehiraNoriyuki en-aut-sei=Kanehira en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Department of Hepatobiliary Pancreatic Surgery, Ehime University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=9 en-affil=Department of Gastroenterological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= en-keyword=Liver resection kn-keyword=Liver resection en-keyword=Robotic surgery kn-keyword=Robotic surgery en-keyword=Training kn-keyword=Training en-keyword=Outcomes kn-keyword=Outcomes END start-ver=1.4 cd-journal=joma no-vol=29 cd-vols= no-issue=2 article-no= start-page=156 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250411 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinical-level screening of sleep apnea syndrome with single-lead ECG alone is achievable using machine learning with appropriate time windows en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose To establish a simple and noninvasive screening test for sleep apnea (SA) that imposes less burden on potential patients. The specific objective of this study was to verify the effectiveness of past and future single-lead electrocardiogram (ECG) data from SA occurrence sites in improving the estimation accuracy of SA and sleep apnea syndrome (SAS) using machine learning.
Methods The Apnea-ECG dataset comprising 70 ECG recordings was used to construct various machine-learning models. The time window size was adjusted based on the accuracy of SA detection, and the performance of SA detection and SAS diagnosis (apnea?hypopnea index???5 was considered SAS) was compared.
Results Using ECG data from a few minutes before and after the occurrence of SAs improved the estimation accuracy of SA and SAS in all machine learning models. The optimal range of the time window and achieved accuracy for SAS varied by model; however, the sensitivity ranged from 95.7 to 100%, and the specificity ranged from 91.7 to 100%.
Conclusions ECG data from a few minutes before and after SA occurrence were effective in SA detection and SAS diagnosis, confirming that SA is a continuous phenomenon and that SA affects heart function over a few minutes before and after SA occurrence. Screening tests for SAS, using data obtained from single-lead ECGs with appropriate past and future time windows, should be performed with clinical-level accuracy. en-copyright= kn-copyright= en-aut-name=YamaneTakahiro en-aut-sei=Yamane en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiiMasanori en-aut-sei=Fujii en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MoritaMizuki en-aut-sei=Morita en-aut-mei=Mizuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Biomedical Informatics, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Geriatric Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Biomedical Informatics, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=Disease screening kn-keyword=Disease screening en-keyword=Sleep apnea syndrome (SAS) kn-keyword=Sleep apnea syndrome (SAS) en-keyword=Single-lead ECG kn-keyword=Single-lead ECG en-keyword=Artificial intelligence kn-keyword=Artificial intelligence en-keyword=Machine learning kn-keyword=Machine learning END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250403 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The association between objectively measured physical activity and home blood pressure: a population-based real-world data analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Few studies have examined the association of objectively measured habitual physical activity (PA) and sedentary behavior with out-of-office blood pressure (BP). We investigated the associations of objectively measured PA intensity time, sedentary time, and step count with at-home BP. Using accelerometer-recorded PA indices and self-measured BP in 368 participants (mean age, 53.8 years; 58.7% women), we analyzed 115,575 records of each parameter between May 2019 and April 2024. PA intensities were categorized as light (2.0?2.9 metabolic equivalents [METs]); moderate (3.0?5.9 METs); vigorous (?6.0 METs), or sedentary (<2.0 METs): the median [interquartile ranges] for these variables was 188 [146?232], 83 [59?114], 1 [0?2], 501 [428?579] minutes, respectively, and for step count, was 6040 [4164?8457]. Means [standard deviations] for systolic and diastolic BP were 116.4 [14.2] and 75.2 [9.3] mmHg, respectively. A mixed-effect model adjusted for possible confounders showed that 1-h longer in vigorous PA was associated with lower systolic and diastolic BP (?1.69 and ?1.09?mmHg, respectively). A 1000-step increase in step count was associated with lower systolic and diastolic BP (?0.05 and ?0.02?mmHg, respectively). Associations were more pronounced among men and participants aged <60 years. Sedentary time was positively associated with BP in men and participants aged <60 years, but inversely associated with BP in women and participants aged ?60 years. Our findings suggest that more PA and less sedentary behavior were associated with BP reduction, particularly among men and participants aged <60 years. However, the clinical relevance of this effect remains uncertain because of its modest magnitude. en-copyright= kn-copyright= en-aut-name=KinutaMinako en-aut-sei=Kinuta en-aut-mei=Minako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HisamatsuTakashi en-aut-sei=Hisamatsu en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TaniguchiKaori en-aut-sei=Taniguchi en-aut-mei=Kaori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FukudaMari en-aut-sei=Fukuda en-aut-mei=Mari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakahataNoriko en-aut-sei=Nakahata en-aut-mei=Noriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KandaHideyuki en-aut-sei=Kanda en-aut-mei=Hideyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Environmental Medicine and Public Health, Izumo, Shimane University Faculty of Medicine kn-affil= affil-num=4 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Health and Nutrition, The University of Shimane Faculty of Nursing and Nutrition kn-affil= affil-num=6 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue= article-no= start-page=1 end-page=9 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Corporate decision-making process for exploration time kn-title=知の探索時間についての企業の意思決定プロセス en-subtitle= kn-subtitle= en-abstract= kn-abstract=In order for companies to innovate through business co-creation, it is necessary to explore a wide range of external knowledge and technologies. However, there is no clear answer as to how much time should be spent for exploration. Under these circumstances, companies must take into account constraints such as the amount of management resources that can be invested, and make decisions about the time to spend for exploration. The purpose of this paper is to clarify the process of how companies that have introduced corporate accelerator program recognize the relationship between the program period and the results of business co-creation, and how they make decisions about the program period. We conducted a case study of several companies that have introduced corporate accelerator program in Japan. In addition, this paper established a hypothesis about decision-making about the time for exploration from case studies. en-copyright= kn-copyright= en-aut-name=SHIMIZUTakeshi en-aut-sei=SHIMIZU en-aut-mei=Takeshi kn-aut-name=志水武史 kn-aut-sei=志水 kn-aut-mei=武史 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems Okayama University kn-affil=国立大学法人岡山大学学術研究院ヘルスシステム統合科学研究学域 en-keyword=corporate accelerator program kn-keyword=corporate accelerator program en-keyword=co-creation kn-keyword=co-creation en-keyword=exploration kn-keyword=exploration en-keyword=Time Compression Diseconomies kn-keyword=Time Compression Diseconomies END start-ver=1.4 cd-journal=joma no-vol=37 cd-vols= no-issue=1 article-no= start-page=16 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250403 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The preoperative flexion tear gap affects postoperative meniscus stability after pullout repair for medial meniscus posterior root tear en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background We investigated whether the preoperative flexion tear gap (FTG) observed in open magnetic resonance imaging (MRI) affects meniscus stability after medial meniscus (MM) posterior root (MMPR) repairs. Furthermore, time-correlated MRI findings from MMPR tear occurrence were evaluated.
Methods This retrospective observational study included 54 patients (mean age, 64.6 years; 13 males and 41 females) who underwent pullout repair for radial degenerative MMPR tear. Meniscus stability (scored 0-4 points) was assessed using a semi-quantitative arthroscopic scoring system during second-look arthroscopy 1 year postoperatively. The FTG was evaluated on preoperative axial MRI at 90 degrees knee flexion. Other MRI measurements included MM extrusion (MME) at 10 degrees knee flexion, MM posterior extrusion (MMPE) at 90 degrees knee flexion, and MM posteromedial extrusion (MMpmE) at 90 degrees knee flexion preoperatively and 1 year postoperatively. The correlation between the arthroscopic stability score and MRI findings was investigated. A receiver-operating characteristic curve was calculated to predict a good meniscus healing score (3-4 points). The correlation between the FTG and patient demographics, including time from injury to MRI, was analyzed.
Results At 1 year postoperatively, MME increased by 1.1 mm, while MMpmE and MMPE decreased by 0.4 mm and 1.0 mm, respectively. The meniscus stability score was negatively correlated with the preoperative FTG (r = -0.61, p < 0.01). The time from injury to MRI was significantly correlated with the preoperative FTG. The receiver-operating characteristic curve identified an FTG cut-off value of 8.7 mm for predicting good postoperative stability, with sensitivity and specificity of 67% and 85%, respectively.
Conclusions FTG evaluated with open MRI at 90 degrees knee flexion was associated with time from injury and affected meniscus stability following pullout repair. MMPR tears should be treated in the early phase to increase meniscus healing stability. en-copyright= kn-copyright= en-aut-name=TamuraMasanori en-aut-sei=Tamura en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FurumatsuTakayuki en-aut-sei=Furumatsu en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KitayamaTakahiro en-aut-sei=Kitayama en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YokoyamaYusuke en-aut-sei=Yokoyama en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkazakiYuki en-aut-sei=Okazaki en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KawadaKoki en-aut-sei=Kawada en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Medial meniscus kn-keyword=Medial meniscus en-keyword=Posterior root tear kn-keyword=Posterior root tear en-keyword=Distance kn-keyword=Distance en-keyword=Pullout repair kn-keyword=Pullout repair en-keyword=Second-look arthroscopy kn-keyword=Second-look arthroscopy END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=6 article-no= start-page=619 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250313 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of Trehalose on Halitosis: A Randomized Cross-Over Clinical Trial en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: Halitosis is a condition characterized by an unpleasant malodor. Intra-oral halitosis is caused by volatile sulfur compounds (VSCs) and can be associated with oral dryness. Trehalose is one of the materials used to relieve oral dryness. The aim of the present study was to investigate the effect of trehalose on halitosis. Methods: This prospective, double-blinded, placebo-controlled, cross-over study enrolled volunteers from Okayama University Hospital. The participants were randomly divided into two groups, with one group receiving trehalose (a 10% trehalose solution) and the other receiving a placebo (distilled water) in a 1:1 allocation. The primary study outcome was the subjective organoleptic test. The secondary outcomes were the concentrations of the VSCs, which were measured using a portable gas chromatography device, and the oral moisture status, which was measured using an oral moisture meter. The planned sample size was 10 participants based on the previous study. Results: The final intention-to-treat analysis was performed using the data from 9 participants. After applying 10% trehalose as an oral spray, the organoleptic score decreased in a time-dependent manner. However, no significant differences were seen between the trehalose and placebo groups. In terms of secondary outcomes, the oral moisture levels increased immediately after the trehalose spray application, and significant differences in the amount of change from the baseline were seen between the trehalose and placebo groups (p = 0.047). No significant differences were seen in any of the other variables (p > 0.05). Conclusions: We could not identify any positive effects on halitosis from a one-time 10% trehalose application as an oral spray in this prospective, double-blinded, placebo-controlled, cross-over study. However, the trehalose application immediately improved the oral moisture levels and was useful for treating oral dryness. en-copyright= kn-copyright= en-aut-name=MiyaiHisataka en-aut-sei=Miyai en-aut-mei=Hisataka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TomofujiTakaaki en-aut-sei=Tomofuji en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MizunoHirofumi en-aut-sei=Mizuno en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoritaManabu en-aut-sei=Morita en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakaharaMomoko en-aut-sei=Nakahara en-aut-mei=Momoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KataokaKota en-aut-sei=Kataoka en-aut-mei=Kota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SumitaIchiro en-aut-sei=Sumita en-aut-mei=Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UchidaYurika en-aut-sei=Uchida en-aut-mei=Yurika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ToyamaNaoki en-aut-sei=Toyama en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=YokoiAya en-aut-sei=Yokoi en-aut-mei=Aya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=Yamanaka-KohnoReiko en-aut-sei=Yamanaka-Kohno en-aut-mei=Reiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=TakeuchiNoriko en-aut-sei=Takeuchi en-aut-mei=Noriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MaruyamaTakayuki en-aut-sei=Maruyama en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=EkuniDaisuke en-aut-sei=Ekuni en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Community Oral Health, School of Dentistry, Asahi University kn-affil= affil-num=3 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Oral Health Sciences, Faculty of Health Care Sciences, Takarazuka University of Medical and Health Care kn-affil= affil-num=5 en-affil=Department of Preventive Dentistry, Division of Dentistry, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Preventive Dentistry, Division of Dentistry, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Preventive Dentistry, Division of Dentistry, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Preventive Dentistry, Division of Dentistry, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=11 en-affil=Department of Preventive Dentistry, Division of Dentistry, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Preventive Dentistry, Division of Dentistry, Okayama University Hospital kn-affil= affil-num=13 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=14 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=halitosis kn-keyword=halitosis en-keyword=trehalose kn-keyword=trehalose en-keyword=oral dryness kn-keyword=oral dryness en-keyword=cross-over study kn-keyword=cross-over study en-keyword=randomized trial kn-keyword=randomized trial END start-ver=1.4 cd-journal=joma no-vol=59 cd-vols= no-issue= article-no= start-page=25 end-page=44 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A Study on the Relationship between Kazuo Inamori's Philosophy, the Teachings of Nanshu Saigo, and the Iroha Poem by Prince Jisshin kn-title=稲盛和夫のフィロソフィーと西郷南洲翁遺訓及び日新公いろは歌の連関についての考察 en-subtitle= kn-subtitle= en-abstract=Kazuo Inamori is a rare business leader who founded DDI, the predecessor of Kyocera and KDDI, in one generation, and grew it into a trillion-yen company. He also rebuilt the bankrupt Japan Airlines (JAL) in three years and led it to relisting. He has not only led tens of thousands of people with his unique management method called amoeba management, but also with management principles. What are the roots of the way of life that a manager of a small and medium-sized business has derived from management? What is the Goju education that is the foundation of Satsuma, where he was born and raised? From the perspective of business management, it is interesting to know what it is like.
How is it related to Saigo Nanshu Ikun, the record of the words and deeds of Saigo Takamori, a local hero whom Kazuo Inamori met after founding Kyocera and used as the basis of his own management philosophy, and Shimazu Nisshin Iroha Uta, left by Shimazu Tadayoshi (Nissin), the father of Shimazu Takahisa, the 15th lord of the Shimazu clan who unified southern Kyushu, including Satsuma and Hyuga, in the 16th century? First of all, I am interested in the relationship between the ideas of the three men born in Satsuma. In this study, we used the grounded theory approach, a qualitative research method, to analyze the correlation between Kazuo Inamori's philosophy, the teachings of Nanshu Saigo, and the Nisshin Iroha Uta. As a result, the analysis revealed that the three concepts are related across 400 years of time. In particular, Kazuo Inamori's philosophy is not only positively influenced by the teachings of Nanshu Saigo, which are the words and deeds of Takamori Saigo, whom Kazuo Inamori admires, but also by the Nisshin Iroha Uta, which dates back 400 years, due to his education in Satsuma. It is believed that the ideals that the people of Satsuma have inherited for 400 years contain concepts that should be the foundation for people's lives, or that should be important core ideas and qualities in life, regardless of the era. kn-abstract=　一代で京セラやKDDIの前身となる第二電電（DDI）を創業し、合計数兆円企業に育て、倒産した日本航空（JAL）を3年で再建し、再上場に導いた稀代の経営者稲盛和夫は、アメーバ経営という独自の経営手法だけでなく、理念経営により数万人を導いてきた。中小企業の一経営者が経営の中から導き出した人生成功の処世術のルーツは何処にあるのか。生まれ育った薩摩の基礎となる郷中（ごじゅう）教育とは何か、などについて経営学の観点から関心が湧く。
　稲盛和夫が京セラ創業以降に出会い、自ら経営理念の基礎とした地元の偉人である西郷隆盛の言行録である西郷南洲翁遺訓及び16世紀に薩摩や日向など南九州を統一した島津家第15代領主島津貴久公の実父島津忠良（日新）が残した、島津日新公いろは歌とどのように連関があるのか。そもそも薩摩生まれの3名の思想にどのような連関があるのか、についても関心が湧く。この研究では、質的研究法であるグラウンデッド・セオリー・アプローチを援用して、稲盛和夫のフィロソフィーと西郷南洲翁遺訓及び日新公いろは歌の連関について分析した。結果的に3つの概念は400年の時代を超えて、連関していることが分析により明らかになった。特に稲盛和夫のフィロソフィーが稲盛和夫が敬愛する西郷隆盛の言行録である西郷南洲翁遺訓に正の影響を受けているだけでなく、薩摩での教育を背景に、400年前に遡る日新公いろは歌からも正の影響を受けていることが明らかになった。400年に渡り薩摩の人々が受け継いできた理念には、時代を超えても人が生きていく中で基礎とすべき、もしくは人生で重要なコアな思想・資質とすべき概念があると考えられる。 en-copyright= kn-copyright= en-aut-name=MACHIDAHisashi en-aut-sei=MACHIDA en-aut-mei=Hisashi kn-aut-name=町田尚史 kn-aut-sei=町田 kn-aut-mei=尚史 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学教育推進機構 en-keyword=稲盛和夫 (Kazuo Inamori) kn-keyword=稲盛和夫 (Kazuo Inamori) en-keyword=フィロソフィー (philosophy) kn-keyword=フィロソフィー (philosophy) en-keyword=西郷隆盛 (Takamori Saigo) kn-keyword=西郷隆盛 (Takamori Saigo) en-keyword=西郷南洲翁遺訓 (the teachings of Nanshu Saigo) kn-keyword=西郷南洲翁遺訓 (the teachings of Nanshu Saigo) en-keyword=島津忠良（日新） (Tadayoshi Shimazu (Nissin)) kn-keyword=島津忠良（日新） (Tadayoshi Shimazu (Nissin)) en-keyword=日新公いろは歌 (Nisshin Iroha Uta) kn-keyword=日新公いろは歌 (Nisshin Iroha Uta) en-keyword=グラウンデッド・セオリー・アプローチ (grounded theory approach) kn-keyword=グラウンデッド・セオリー・アプローチ (grounded theory approach) END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=191 end-page=205 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Prevention of Apathy in High School Students Perspective on Time Management and Future Prospects kn-title=アパシー傾向からみた高校生の無気力の予防について　―タイムマネジメント，将来展望との関係を通して― en-subtitle= kn-subtitle= en-abstract=　According to the Ministry of Education in Japan (2023), apathy is the leading cause of truancy among high school students, with the percentage of nonattendance at 40%. Therefore, this study aimed to examine the prevention of apathy among high school students. Apathy among college students has been examined as a propensity for apathy. This study presupposes that apathy among high school students is also associated with a propensity for apathy. Two hundred and nineteen high school students were participated in this research. We assumed time management (TM) and future prospects (self-fulfillment, goal-directedness, and hopefulness) would be preventive factors against apathetic tendencies for them. The study findings indicate that self-fulfillment may significantly reduce apathy, with hopefulness also contributing to reducing apathy. Additionally, the characteristics of apathy tendency, specifically lack of self, were found to be differently related to students' TM skills. In other words, the findings suggest that goal-directedness may alleviate apathy among students struggling with TM. kn-abstract=　不登校の主たる要因の1位は「無気力・不安」で40.0%を占める（文部科学省，2023）。このことは，不登校でない生徒の中にも，無気力を感じている生徒がかなりいることを示唆している。そこで本研究は，高校生の無気力とその予防について検討する。無気力は，大学生を対象にアパシー傾向として検討されてきた。そこで高校生の無気力をアパシー傾向として捉え，加えてそれを予防するものについても併せて検討した。予防法の候補として，タイムマネジメント（以下，TM）と将来展望（現在の充実感・目標指向性・希望）を想定し，高校生219名を対象に，これらの関係を検討した。分析の結果，無気力を低減するのは，現在の充実感，希望であり，特に前者が有効である可能性を示せた。一方で，アパシー傾向の自分のなさでは，TM のタイプによって異なる関係がみられた。つまり，TM が苦手な生徒では，希望よりも，目前の目標に目を向けることが無気力を低減できる可能性が示唆された。 en-copyright= kn-copyright= en-aut-name=ASADAAsuka en-aut-sei=ASADA en-aut-mei=Asuka kn-aut-name=麻田明日香 kn-aut-sei=麻田 kn-aut-mei=明日香 aut-affil-num=1 ORCID= en-aut-name=AOKITazuko en-aut-sei=AOKI en-aut-mei=Tazuko kn-aut-name=青木多寿子 kn-aut-sei=青木 kn-aut-mei=多寿子 aut-affil-num=2 ORCID= affil-num=1 en-affil=KANKO GAKUSEIFUKU CO., LTD. kn-affil=菅公学生服 affil-num=2 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域　教授 en-keyword=高校生 (High School Students) kn-keyword=高校生 (High School Students) en-keyword=無気力 kn-keyword=無気力 en-keyword=アパシー傾向 (Apathy tendency) kn-keyword=アパシー傾向 (Apathy tendency) en-keyword=タイムマネジメント (Time Management) kn-keyword=タイムマネジメント (Time Management) en-keyword=将来展望 (Future Prospect) kn-keyword=将来展望 (Future Prospect) en-keyword=Prevention kn-keyword=Prevention END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250312 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Droplet Impact Behavior on Convex Surfaces with a Circumferential Wettability Difference en-subtitle= kn-subtitle= en-abstract= kn-abstract=Controlling the bouncing behavior of the impacting droplets is an important issue for splay cooling, icing prevention, and other applications. The bouncing behavior of impacting droplets on superhydrophobic curved surfaces and flat substrates with a wettability difference has been widely investigated, and droplets impacting these surfaces show shorter contact times than those on superhydrophobic flat surfaces and droplet transport. However, there have been few studies on the droplet impact behavior on curved surfaces with a wettability difference, where efficient droplet control could be achieved by combining the features. In the present study, droplet impact experiments were conducted using copper cylinders with different circumferential wettabilities from hydrophilic to superhydrophobic, varying the impact velocity, cylinder diameter, and rotation angle. Droplets that impacted the wettability boundary showed asymmetric deformation and moved to the hydrophilic side, owing to the driving force of the wettability difference. Moreover, the droplet behavior was classified into four types: the droplet bounced off the surface, the droplet bounced off the surface and split, the droplet attached to the surface, and the droplet attached to the surface and split. The droplet behavior was estimated by using the maximum spreading width of the droplet impacted on the flat substrate. We evaluated whether the droplets attached to the surface or bounced off the surface after impact using the Weber number and rotation angle, and the estimations were in agreement with the experimental results for cylinder diameters of 4 and 6 mm. en-copyright= kn-copyright= en-aut-name=IshikawaTaku en-aut-sei=Ishikawa en-aut-mei=Taku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamadaYutaka en-aut-sei=Yamada en-aut-mei=Yutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IsobeKazuma en-aut-sei=Isobe en-aut-mei=Kazuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HoribeAkihiko en-aut-sei=Horibe en-aut-mei=Akihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue=9 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2016 dt-pub=20160908 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=S-nitrosylation of laforin inhibits its phosphatase activity and is implicated in Lafora disease en-subtitle= kn-subtitle= en-abstract= kn-abstract=Recently, the relation between S-nitrosylation by nitric oxide (NO), which is over?produced under pathological conditions and neurodegenerative diseases, includingAlzheimer’s and Parkinson’s diseases, has become a focus of attention. Although mostcases of Parkinson’s disease are known to be caused by mutations in the Parkin gene, arecent finding has indicated that S-nitrosylation of Parkin affects its enzymatic activityand leads to the Parkinsonian phenotype. Therefore, it is important to understand thefunction of S-nitrosylated proteins in the pathogenesis of neurodegenerative diseases.Lafora disease (LD, OMIM 254780) is a neurodegenerative disease characterized by theaccumulation of insoluble glucans called Lafora bodies (LBs). LD is caused by mutationsin genes that encode the glucan phosphatase, Laforin, or the E3 ubiquitin ligase, Malin.In this study, we hypothesized that LD may be caused by S-nitrosylation of Laforin,which is similar to the finding that Parkinson’s disease is caused by S-nitrosylation ofParkin. To test this hypothesis, we first determined whether Laforin was S-nitrosylatedusing a biotin switch assay, and compared the three main functions of unmodified andS-nitrosylated Laforin, namely glucan- and Malin-binding activity and phosphataseactivity. Furthermore, we examined whether the numbers of LBs were changed byNO in the cells expressing wild-type Laforin. Here, we report for the first time thatS-nitrosylation of Laforin inhibited its phosphatase activity and that LB formation wasincreased by an NO donor. Our results suggest a possible hypothesis for LD pathogenesis; that is, the decrease in phosphatase activity of Laforin by S-nitrosylation leads toincreased LB formation. Therefore, LD may be caused not only by mutations in theLaforin or Malin genes, but also by the S-nitrosylation of Laforin. en-copyright= kn-copyright= en-aut-name=ToyotaRikako en-aut-sei=Toyota en-aut-mei=Rikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HonjoYasuko en-aut-sei=Honjo en-aut-mei=Yasuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ImajoRisa en-aut-sei=Imajo en-aut-mei=Risa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SatohAyano en-aut-sei=Satoh en-aut-mei=Ayano kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University; Research Institute for Radiation Biology and Medicine, Hiroshima University kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University; Research Institute for Radiation Biology and Medicine, Hiroshima University kn-affil= affil-num=4 en-affil=Graduate School of Natural Science and Technology, Okayama University; Research Institute for Radiation Biology and Medicine, Hiroshima University kn-affil= en-keyword=S-Nitrosylation Of Laforin kn-keyword=S-Nitrosylation Of Laforin en-keyword=Post-Translational Modification kn-keyword=Post-Translational Modification en-keyword=Nitrosylation kn-keyword=Nitrosylation en-keyword=Phosphatase kn-keyword=Phosphatase en-keyword=Glucan-Binding kn-keyword=Glucan-Binding END start-ver=1.4 cd-journal=joma no-vol=45 cd-vols= no-issue=3 article-no= start-page=32 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250307 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Rapid development of naked malting barley germplasm through targeted mutagenesis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Covered barley (Hordeum vulgare) has historically been preferred for malting, as the husk in this plant protects the embryo during harvest and acts as a filter during brewing. Naked barley, which is typically used as food, has the potential to be used in brewing due to recent technical advances, but the grains contain higher levels of β-glucan and polyphenols, which are undesirable in brewing. Introducing the naked trait into brewing cultivars through crossing is time-consuming due to the need to eliminate these undesirable traits. In this study, we rapidly developed naked barley that is potentially suitable for malting by introducing targeted mutations into Nudum (NUD) using CRISPR/Cas9-mediated targeted mutagenesis. The doubled haploid line ‘DH120366’, which was used as the parental line, was derived from a cross between two covered malting barley cultivars. We generated CRISPR/Cas9-mediated targeted mutagenized barley harboring mutations in NUD via Agrobacterium tumefaciens-mediated transformation and confirmed the presence of mosaic mutations in one individual from among 16 T0 transformants. We sowed T1 grains exhibiting the naked trait and sequenced the NUD gene in these T1 seedlings, identifying two types of mutations. Shotgun high-throughput whole-genome sequencing confirmed the absence of the transgene in at least one nud mutant line following k-mer-based analysis. Cultivation in a closed growth chamber revealed no significant differences in agronomic traits between the nud mutants and the wild type. This study demonstrates the feasibility of rapidly developing naked barley with potential use for malting and brewing by targeting only NUD via targeted mutagenesis. en-copyright= kn-copyright= en-aut-name=HisanoHiroshi en-aut-sei=Hisano en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakaiHiroaki en-aut-sei=Sakai en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HamaokaMika en-aut-sei=Hamaoka en-aut-mei=Mika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MunemoriHiromi en-aut-sei=Munemori en-aut-mei=Hiromi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AbeFumitaka en-aut-sei=Abe en-aut-mei=Fumitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MeintsBrigid en-aut-sei=Meints en-aut-mei=Brigid kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SatoKazuhiro en-aut-sei=Sato en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HayesPatrick M. en-aut-sei=Hayes en-aut-mei=Patrick M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=Research Center for Advanced Analysis, National Agriculture and Food Research Organization kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=4 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=5 en-affil=Institute of Crop Science, National Agriculture and Food Research Organization kn-affil= affil-num=6 en-affil=Department Crop and Soil Science, Oregon State University kn-affil= affil-num=7 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=8 en-affil=Department Crop and Soil Science, Oregon State University kn-affil= en-keyword=Hordeum vulgare kn-keyword=Hordeum vulgare en-keyword=Covered (hulled) kn-keyword=Covered (hulled) en-keyword=Naked (hull-less) kn-keyword=Naked (hull-less) en-keyword=Genome editing kn-keyword=Genome editing en-keyword=CRISPR/Cas9 kn-keyword=CRISPR/Cas9 en-keyword=Transformation amenability kn-keyword=Transformation amenability END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=5 article-no= start-page=2421 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250224 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Deep Reinforcement Learning for Dynamic Pricing and Ordering Policies in Perishable Inventory Management en-subtitle= kn-subtitle= en-abstract= kn-abstract=Perishable goods have a limited shelf life, and inventory should be discarded once it exceeds its shelf life. Finding optimal inventory management policies is essential since inefficient policies can lead to increased waste and higher costs. While many previous studies assume the perishable inventory is processed following the First In, First Out rule, it does not reflect customer purchasing behavior. In practice, customers' preferences are influenced by the shelf life and price of products. This study optimizes inventory and pricing policies for a perishable inventory management problem considering age-dependent probabilistic demand. However, introducing dynamic pricing significantly increases the complexity of the problem. To tackle this challenge, we propose eliminating irrational actions in dynamic programming without sacrificing optimality. To solve this problem more efficiently, we also implement a deep reinforcement learning algorithm, proximal policy optimization, to solve this problem. The results show that dynamic programming with action reduction achieved an average of 63.1% reduction in computation time compared to vanilla dynamic programming. In most cases, proximal policy optimization achieved an optimality gap of less than 10%. Sensitivity analysis of the demand model revealed a negative correlation between customer sensitivity to shelf lives or prices and total profits. en-copyright= kn-copyright= en-aut-name=NomuraYusuke en-aut-sei=Nomura en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LiuZiang en-aut-sei=Liu en-aut-mei=Ziang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishiTatsushi en-aut-sei=Nishi en-aut-mei=Tatsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=reinforcement learning kn-keyword=reinforcement learning en-keyword=supply chain kn-keyword=supply chain en-keyword=inventory management kn-keyword=inventory management en-keyword=perishable inventory kn-keyword=perishable inventory en-keyword=dynamic pricing kn-keyword=dynamic pricing END start-ver=1.4 cd-journal=joma no-vol=429 cd-vols= no-issue= article-no= start-page=529 end-page=565 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250605 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Polyhedral entire solutions in reaction-diffusion equations en-subtitle= kn-subtitle= en-abstract= kn-abstract=This paper studies polyhedral entire solutions to a bistable reaction-diffusion equation in Rn.

Current guidelines recommend periodic surveillance; however, the natural course and long-term outcomes of gastric SELs have not been sufficiently investigated. This systematic review aimed to synthesize evidence on the progression, growth rate, and risk factors associated with gastric SELs to inform clinical management strategies. Methods: A comprehensive search of PubMed was conducted for peer-reviewed studies published between January 2000 and November 2024. Eligible studies included original studies on the follow-up and progression of gastric SELs. Non-English articles, reviews, case reports, and unrelated topics were excluded. In total, 277 articles were screened, with 15 additional articles identified through manual screening. Ultimately, 41 articles were included in the analysis. The study protocol is registered in PROSPERO (CRD42024614865). Results: Large-scale studies reported low growth rates of 2.0-8.5% over 2.0-5.0 years, while smaller studies reported a broader range of growth rates of 5.4-28.4%. The factors contributing to these discrepancies include patient selection, follow-up duration, and growth criteria. Risk factors for lesion size increase include larger initial lesion size, irregular margins, heterogeneous echo patterns, and certain tumor locations. Conclusions: These findings underscore the need for individualized management strategies based on lesion size, imaging characteristics, and risk factors. The close monitoring of high-risk lesions is crucial for timely intervention. Standardized growth criteria and optimized follow-up protocols are essential for improving clinical decision making and patient outcomes. en-copyright= kn-copyright= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Internal Medicine, Japanese Red Cross Society Himeji Hospital kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=esophagogastroduodenoscopy kn-keyword=esophagogastroduodenoscopy en-keyword=gastric lesions kn-keyword=gastric lesions en-keyword=gastrointestinal stromal tumor kn-keyword=gastrointestinal stromal tumor en-keyword=subepithelial lesion kn-keyword=subepithelial lesion en-keyword=submucosal tumor kn-keyword=submucosal tumor END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=2 article-no= start-page=267 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250122 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Abnormal Expression of Tubular SGLT2 and GULT2 in Diabetes Model Mice with Malocclusion-Induced Hyperglycemia en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: A relationship between malocclusion and the promotion of diabetes has been suggested. In hyperglycemia, the expression of sodium-glucose cotransporter 2 (SGLT2) and the facilitative glucose transporter 2 (GLUT2) is upregulated in proximal tubular cells, leading to an increase in renal glucose reabsorption. The present study aimed to investigate whether malocclusion contributes to diabetic exacerbation. Methods: Streptozotocin (STZ)-induced diabetic mice with malocclusion due to cutting molars were investigated based on increased blood glucose levels. PCR and immunohistochemical analyses were performed on diabetic mice kidneys to investigate the expression of SGLT2 and GLUT2. Results: Animal experiments were performed using 32 mice for 21 days. The time to reach a diabetic condition in STZ-administered mice was shorter with malocclusion than without malocclusion. The increase and mean blood glucose levels in STZ-administered mice were steeper and higher with malocclusion than without malocclusion. Urea albumin, BUN, and CRE levels were higher in diabetic mice with malocclusion than in diabetic mice without. Immunoreaction with anti-SGLT2 and anti-GLUT2 in the renal tissue of STZ-administered mice was stronger with malocclusion than without malocclusion. The amounts of SGLT2 and GLUT2 mRNA in the renal tissue in STZ-administered mice were higher with malocclusion than without malocclusion. The amounts of TNF-a and IL-6 mRNA in the large intestinal tissue in STZ-administered mice were higher with malocclusion than without malocclusion. Conclusions: Our results indicate that malocclusion accelerates the tubular expression of SGLT2 and GLUT2 under hyperglycemia. Malocclusion may be a diabetes-exacerbating factor with increased poor glycemic control due to shortened occlusion time resulting from swallowing food without chewing. en-copyright= kn-copyright= en-aut-name=KajiwaraKoichiro en-aut-sei=Kajiwara en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TamaokiSachio en-aut-sei=Tamaoki en-aut-mei=Sachio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SawaYoshihiko en-aut-sei=Sawa en-aut-mei=Yoshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Oral Growth & Development, Fukuoka Dental College kn-affil= affil-num=2 en-affil=Department of Oral Growth & Development, Fukuoka Dental College kn-affil= affil-num=3 en-affil=Department of Oral Function & Anatomy, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=malocclusion kn-keyword=malocclusion en-keyword= hyperglycemia kn-keyword= hyperglycemia en-keyword= SGLT2 kn-keyword= SGLT2 en-keyword= GLUT2 kn-keyword= GLUT2 END start-ver=1.4 cd-journal=joma no-vol=106 cd-vols= no-issue= article-no= start-page=103026 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202506 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The antimalarial activity of transdermal N-89 mediated by inhibiting ERC gene expression in P. Berghei-infected mice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Through studies of new antimalarial drugs, we identified 1,2,6,7-tetraoxaspiro[7.11]nonadecane (N-89) as a potential drug candidate. Here, we analyzed the antimalarial action of a transdermal formulation (td) of N-89, designed for easy use by children, using Plasmodium berghei-infected mice as a model for malaria patients. The td N-89 or artemisinin (ART) formulation was transdermally administered to P. berghei-infected mice with 0.2?0.4 % parasitemia, twice daily for four days, at an effective dose of 90 % for malaria. Parasitemia was decreased in td N-89 and td ART groups during the drug treatment; then, three of the eight mice in td N-89 group were completely cured without relapse. Additionally, abnormal trophozoites in td N-89 group were observed 8 h after administration and increased up to 24 h. To study the change in endoplasmic reticulum-resident calcium-binding protein (ERC) gene expression with td N-89, we investigated the gene expression of P. berghei ERC (PbERC) after td N-89 treatment. PbERC gene expression was increased time-dependently in control group, and was statistically decreased at 4 and 8 h and then increased similar to that of control group at 12 h in td ART group. In contrast, the expression in td N-89 group was almost steady starting from 0 h. We also studied parasite egress-related genes expression after td N-89 treatment, plasmepsin X, subtilisin-like protease 1 and merozoite surface protein 1, were suppressed at 12 h compared to control group. These results suggest that N-89 affects function of endoplasmic reticulum via regulating gene suppression and subsequently parasite growth is inhibited. en-copyright= kn-copyright= en-aut-name=MatsumoriHiroaki en-aut-sei=Matsumori en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DinhThi Quyen en-aut-sei=Dinh en-aut-mei=Thi Quyen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyoshiShin-ichi en-aut-sei=Miyoshi en-aut-mei=Shin-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoritaMasayuki en-aut-sei=Morita en-aut-mei=Masayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KimHye-Sook en-aut-sei=Kim en-aut-mei=Hye-Sook kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Division of International Infectious Diseases Control, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Division of International Infectious Diseases Control, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Research Center for Intestinal Health Science, Okayama University kn-affil= affil-num=4 en-affil=Department of Anatomy, Kawasaki Medical School kn-affil= affil-num=5 en-affil=Division of International Infectious Diseases Control, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Synthetic antimalarial endoperoxide kn-keyword=Synthetic antimalarial endoperoxide en-keyword=Transdermal N-89 kn-keyword=Transdermal N-89 en-keyword=Artemisinin kn-keyword=Artemisinin en-keyword=In vivo kn-keyword=In vivo en-keyword=Abnormal trophozoite kn-keyword=Abnormal trophozoite en-keyword=Endoplasmic reticulum-resident calcium-binding protein (ERC) kn-keyword=Endoplasmic reticulum-resident calcium-binding protein (ERC) en-keyword=Parasite egress-related gene kn-keyword=Parasite egress-related gene END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=1 article-no= start-page=51 end-page=58 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202502 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Photoinitiators Induce Histamine Production in Human Mast Cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Photoinitiators are used in the manufacture of many daily products, and may produce harmful effects due to their cytotoxicity. They have also been detected in human serum. Here, we investigated the histamine-producing effects in HMC-1 cells and the inflammatory cytokine release effects in RAW264 cells for four photoinitiators: 1-hydroxycyclohexyl phenyl ketone; 2-isopropylthioxanthone; methyl 2-benzoylbenzoate; and 2-methyl-4´-(methylthio)-2-morpholinopropiophenone. All four promoted histamine production in HMC-1 cells; however, they did not significantly affect the release of inflammatory cytokines in RAW264 cells. These findings suggest that these four photoinitiators induce inflammatory cytokine-independent histamine production, potentially contributing to histamine-mediated chronic inflammation in vitro. en-copyright= kn-copyright= en-aut-name=MiuraTaro en-aut-sei=Miura en-aut-mei=Taro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawasakiYoichi en-aut-sei=Kawasaki en-aut-mei=Yoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HamanoHirofumi en-aut-sei=Hamano en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ZamamiYoshito en-aut-sei=Zamami en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SendoToshiaki en-aut-sei=Sendo en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Clinical Pharmacy, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Laboratory of Clinical Pharmacology and Therapeutics, Kagawa School of Pharmaceutical Sciences, Tokushima Bunri University kn-affil= affil-num=3 en-affil=Department of Clinical Pharmacy, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Clinical Pharmacy, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Clinical Pharmacy, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=photoinitiator kn-keyword=photoinitiator en-keyword=ink kn-keyword=ink en-keyword=injection kn-keyword=injection en-keyword=histamine kn-keyword=histamine en-keyword=inflammation kn-keyword=inflammation END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=1 article-no= start-page=47 end-page=50 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202502 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Immediate Effects of a Single Home-based Rehabilitation Treatment on Balance Performance and Toe-Grip Strength in Elderly Subjects Continuing the Same Rehabilitation Program en-subtitle= kn-subtitle= en-abstract= kn-abstract=We assessed the immediate effects of a home-based rehabilitation (HBR) program on the balance performance and toe-grip strength of 29 older adults (mean±SD age of 75.1±9.9; 16 males, 13 females) who were participating in HBR services provided by Japan’s nursing care insurance system. Their toe-grip strength and balance performance were measured before and after the HBR program. The subjects’ toe-grip strength was significantly improved after the treatment. The subjects who had had a stroke showed a significant improvement after HBR. Contrarily, no significant difference was observed in the subjects’ functional reach results or their one-leg standing time. These results indicate that the exercise regimen provided in the HBR program led to increased excitability of motor units and immediately enhanced the subjects’ toe-grip strength. en-copyright= kn-copyright= en-aut-name=KojimaKazunori en-aut-sei=Kojima en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UjikawaTakuya en-aut-sei=Ujikawa en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OnoToshiro en-aut-sei=Ono en-aut-mei=Toshiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Physical Therapy, Faculty of Health Sciences, Okayama Healthcare Professional University kn-affil= affil-num=2 en-affil=Department of Physical Therapy, Faculty of Rehabilitation, Kawasaki University of Medical Welfare kn-affil= affil-num=3 en-affil=Department of Occupational Therapy, Faculty of Health Sciences, Okayama Healthcare Professional University kn-affil= en-keyword=home-based rehabilitation kn-keyword=home-based rehabilitation en-keyword=toe-grip strength kn-keyword=toe-grip strength en-keyword=balance performance kn-keyword=balance performance END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=1 article-no= start-page=12 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250208 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Voice analysis and deep learning for detecting mental disorders in pregnant women: a cross-sectional study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction Perinatal mental disorders are prevalent, affecting 10-20% of pregnant women, and can negatively impact both maternal and neonatal outcomes. Traditional screening tools, such as the Edinburgh Postnatal Depression Scale (EPDS), present limitations due to subjectivity and time constraints in clinical settings. Recent advances in voice analysis and machine learning have shown potential for providing more objective screening methods. This study aimed to develop a deep learning model that analyzes the voices of pregnant women to screen for mental disorders, thereby offering an alternative to the traditional tools.
Methods A cross-sectional study was conducted among 204 pregnant women, from whom voice samples were collected during their one-month postpartum checkup. The audio data were preprocessed into 5000 ms intervals, converted into mel-spectrograms, and augmented using TrivialAugment and context-rich minority oversampling. The EfficientFormer V2-L model, pretrained on ImageNet, was employed with transfer learning for classification. The hyperparameters were optimized using Optuna, and an ensemble learning approach was used for the final predictions. The model's performance was compared to that of the EPDS in terms of sensitivity, specificity, and other diagnostic metrics.
Results Of the 172 participants analyzed (149 without mental disorders and 23 with mental disorders), the voice-based model demonstrated a sensitivity of 1.00 and a recall of 0.82, outperforming the EPDS in these areas. However, the EPDS exhibited higher specificity (0.97) and precision (0.84). No significant difference was observed in the area under the receiver operating characteristic curve between the two methods (p = 0.759).
Discussion The voice-based model showed higher sensitivity and recall, suggesting that it may be more effective in identifying at-risk individuals than the EPDS. Machine learning and voice analysis are promising objective screening methods for mental disorders during pregnancy, potentially improving early detection.
Conclusion We developed a lightweight machine learning model to analyze pregnant women's voices for screening various mental disorders, achieving high sensitivity and demonstrating the potential of voice analysis as an effective and objective tool in perinatal mental health care. en-copyright= kn-copyright= en-aut-name=OobaHikaru en-aut-sei=Ooba en-aut-mei=Hikaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MakiJota en-aut-sei=Maki en-aut-mei=Jota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MasuyamaHisashi en-aut-sei=Masuyama en-aut-mei=Hisashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Perinatal mental disorders kn-keyword=Perinatal mental disorders en-keyword=Voice analysis kn-keyword=Voice analysis en-keyword=Machine learning kn-keyword=Machine learning en-keyword=Screening kn-keyword=Screening en-keyword=Pregnant women kn-keyword=Pregnant women END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=1 article-no= start-page=e70073 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250129 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Efficacy and safety of endoscopic ultrasonography-guided radiofrequency ablation of small pancreatic neuroendocrine neoplasms: A prospective, pilot study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: Endoscopic ultrasonography (EUS)-guided radiofrequency ablation has recently been introduced as one of the management strategies for small pancreatic neuroendocrine neoplasms (PNENs). However, prospective data on its safety and efficacy remain limited.
Methods: This prospective pilot study was conducted at Okayama University Hospital from May 2023 to December 2024. Patients with grade 1 PNENs <= 15 mm, confirmed by EUS-guided fine-needle aspiration, were included. The primary endpoint was safety (adverse events [AEs] evaluated according to the 2010 guidelines of the American Society for Gastrointestinal Endoscopy. Severe AEs were defined as moderate or higher in American Society for Gastrointestinal Endoscopy grading and grade >= 3. Secondary endpoints included efficacy (complete response on contrast-enhanced computed tomography at 1 and 6 months), treatment details, device failure, diabetes mellitus exacerbation, and overall survival at 6 months.
Results: Five patients with non-functional PNENs (median age: 64 years; median tumor size: 10 mm) were treated. AEs occurred in two patients (40%, 2/5), although none was severe. Both patients developed asymptomatic pseudocysts, one experienced mild pancreatitis, and both resolved with conservative treatment. The complete response rates on contrast-enhanced computed tomography at one and 6 months were 100%. The median procedure time was 16 min without any device failure, and the median hospitalization was 5 days. None of the patients developed new-onset or worsening diabetes mellitus. The 6-month overall survival rate was 100%.
Conclusion: EUS-guided radiofrequency ablation demonstrated a high complete response rate with no severe AEs in this pilot study, suggesting a minimally invasive option for small, low-grade PNENs (jRCTs062230014). en-copyright= kn-copyright= en-aut-name=MatsumotoKazuyuki en-aut-sei=Matsumoto en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID=

disorders (MSDs) can significantly impact individuals' quality of life (QoL), often requiring effective rehabilitation strategies to promote recovery. However, traditional rehabilitation methods can be expensive and may lack engagement, leading to poor adherence to therapy exercise routines. An exergame system can be a solution to this problem. In this paper, we investigate appropriate hand gestures for controlling video games in a rehabilitation exergame system. The Mediapipe Python library is adopted for the real-time recognition of gestures. We choose 10 easy gestures among 32 possible simple gestures. Then, we specify and compare the best and the second-best groups used to control the game. Comprehensive experiments are conducted with 16 students at Andalas University, Indonesia, to find appropriate gestures and evaluate user experiences of the system using the System Usability Scale (SUS) and User Experience Questionnaire (UEQ). The results show that the hand gestures in the best group are more accessible than in the second-best group. The results suggest appropriate hand gestures for game controls and confirm the proposal's validity. In future work, we plan to enhance the exergame system by integrating a diverse set of video games, while expanding its application to a broader and more diverse sample. We will also study other practical applications of the hand gesture control function. en-copyright= kn-copyright= en-aut-name=HusnaRadhiatul en-aut-sei=Husna en-aut-mei=Radhiatul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=BrataKomang Candra en-aut-sei=Brata en-aut-mei=Komang Candra kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AnggrainiIrin Tri en-aut-sei=Anggraini en-aut-mei=Irin Tri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FunabikiNobuo en-aut-sei=Funabiki en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=RahmadaniAlfiandi Aulia en-aut-sei=Rahmadani en-aut-mei=Alfiandi Aulia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FanChih-Peng en-aut-sei=Fan en-aut-mei=Chih-Peng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=3 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=4 en-affil=Department of Information and Communication Systems, Okayama University kn-affil= affil-num=5 en-affil=Department of Electrical Engineering, State Polytechnic of Malang kn-affil= affil-num=6 en-affil=Department of Electrical Engineering, National Chung Hsing University kn-affil= en-keyword=hand gesture kn-keyword=hand gesture en-keyword=application control kn-keyword=application control en-keyword=exergame kn-keyword=exergame en-keyword=SUS kn-keyword=SUS en-keyword=UEQ kn-keyword=UEQ en-keyword=python kn-keyword=python en-keyword=mediapipe kn-keyword=mediapipe END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241224 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The perception of plastic waste and composition of boathouse waste in floating villages on Tonl? Sap Lake, Cambodia en-subtitle= kn-subtitle= en-abstract= kn-abstract=Villagers living on Tonl? Sap (TS) Lake have low incomes and no access to basic public services, such as waste management, domestic water, electricity, and health care. Knowledge of the villagers’ perceptions and the composition of the waste from their boathouses will contribute to constructing a waste collection system with community participation within the framework of waste prevention and reduction. This study surveyed residents living in boathouses in four floating villages on TS Lake, Cambodia, regarding their perceptions and boathouse waste composition to assess the status of plastic waste and the villagers’ environmental awareness and their willingness to participate in waste collection. The household waste survey sought to clarify the amount of plastic waste and other recyclable waste discharged from floating houses. The perception survey revealed that in the wet season, 36% of respondents disposed of plastic waste by open burning/dumping and 40% by discharge into TS Lake; in the dry season, 76% disposed of waste by open burning/dumping, and only 4% discharged waste into TS Lake. An analysis of the boathouse plastic waste composition showed that residents of the floating villages generated 40.21 g plastic waste/day/capita, which was much lower than 340 g/day/capita in the USA, 120 g/day/capita in China, and even 70 g/day/capita in Cambodian on average, but higher than the 10 g/day/capita in India. This study proposes a novel and valuable framework to estimate and determine the level of awareness of people in floating villages related to plastic pollution effects and waste components from boathouses. At the same time, the research results provide an essential scientific basis to be able to develop an effective waste collection system in the area of TS Lake. The proposed framework of this study will help the policy decision-makers in the TS Lake area and those in similar geographical regions facing similar problems. en-copyright= kn-copyright= en-aut-name=Habuer en-aut-sei=Habuer en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiwaraTakeshi en-aut-sei=Fujiwara en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=VinSpoann en-aut-sei=Vin en-aut-mei=Spoann kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ChandaraPhat en-aut-sei=Chandara en-aut-mei=Phat kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TsukijiMakoto en-aut-sei=Tsukiji en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Environmental Management Course, Architecture, Civil Engineering and Environmental Management Program, School of Engineering, Okayama University kn-affil= affil-num=2 en-affil=Environmental Management Course, Architecture, Civil Engineering and Environmental Management Program, School of Engineering, Okayama University kn-affil= affil-num=3 en-affil=Department of Economic Development, Faculty of Development Studies, Royal University of Phnom Penh kn-affil= affil-num=4 en-affil=Department of Natural Resource Management and Development, Faculty of Development Studies, Royal University of Phnom Penh kn-affil= affil-num=5 en-affil=Environmental Management Course, Architecture, Civil Engineering and Environmental Management Program, School of Engineering, Okayama University kn-affil= en-keyword=Boathouse waste composition kn-keyword=Boathouse waste composition en-keyword=Cambodia kn-keyword=Cambodia en-keyword=Floating villages kn-keyword=Floating villages en-keyword=Perception survey kn-keyword=Perception survey en-keyword=Plastic waste kn-keyword=Plastic waste END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=12 article-no= start-page=1184 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241126 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Contributions of the Primary Sensorimotor Cortex and Posterior Parietal Cortex to Motor Learning and Transfer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Transferring learned manipulations to new manipulation tasks has enabled humans to realize thousands of dexterous object manipulations in daily life. Two-digit grasp and three-digit grasp manipulations require different fingertip forces, and our brain can switch grasp types to ensure good performance according to motor memory. We hypothesized that several brain areas contribute to the execution of the new type of motor according to the motor memory. However, the motor memory mechanisms during this transfer period are still unclear. In the present functional magnetic resonance imaging (fMRI) study, we aimed to investigate the cortical mechanisms involved in motor memory during the transfer phase of learned manipulation tasks. Methods: Using a custom-built T-shaped object with an adjustable weight distribution, the participants performed grasp and lift manipulation tasks under different conditions to simulate the learning and transfer phases. The learning phase consisted of four grasp-and-lift repetitions with one motor type, followed by a transfer phase with four repetitions involving different motors (adding or removing a digit). Results: By comparing brain activity in the learning and transfer phases, we identified three regions (the superior frontal gyrus, supramarginal gyrus, and postcentral gyrus) associated with motor memory during the transfer of learned manipulations. Conclusions: Our findings improve the understanding of the role of the posterior parietal cortex in motor memory, highlighting how sensory information from memory and real-time input is integrated to generate novel motor control signals that guide the precise reapplication of control strategies. Furthermore, we believe that these areas contribute to motor learning from motor memory and may serve as key regions of interest for investigating neurodegenerative diseases. en-copyright= kn-copyright= en-aut-name=WangChenyu en-aut-sei=Wang en-aut-mei=Chenyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YuYinghua en-aut-sei=Yu en-aut-mei=Yinghua kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YangJiajia en-aut-sei=Yang en-aut-mei=Jiajia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=fMRI kn-keyword=fMRI en-keyword=motor learning and transfer kn-keyword=motor learning and transfer en-keyword=primary sensorimotor cortex kn-keyword=primary sensorimotor cortex en-keyword=posterior parietal cortex kn-keyword=posterior parietal cortex END start-ver=1.4 cd-journal=joma no-vol=169 cd-vols= no-issue=1 article-no= start-page=e16291 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241222 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Exploring the Role of Ccn3 in Type III Cell of Mice Taste Buds en-subtitle= kn-subtitle= en-abstract= kn-abstract=Different taste cells express unique cell-type markers, enabling researchers to distinguish them and study their functional differentiation. Using single-cell RNA-Seq of taste cells in mouse fungiform papillae, we found that Cellular Communication Network Factor 3 (Ccn3) was highly expressed in Type III taste cells but not in Type II taste cells. Ccn3 is a protein-coding gene involved in various biological processes, such as cell proliferation, angiogenesis, tumorigenesis, and wound healing. Therefore, in this study, we aimed to explore the expression and function of Ccn3 in mouse taste bud cells. Using reverse transcription polymerase chain reaction (RT-PCR), in situ hybridization, and immunohistochemistry (IHC), we confirmed that Ccn3 was predominantly expressed in Type III taste cells. Through IHC, quantitative real-time RT-PCR, gustatory nerve recordings, and short-term lick tests, we observed that Ccn3 knockout (Ccn3-KO) mice did not exhibit any significant differences in the expression of taste cell markers and taste responses compared to wild-type controls. To explore the function of Ccn3 in taste cells, bioinformatics analyses were conducted and predicted possible roles of Ccn3 in tissue regeneration, perception of pain, protein secretion, and immune response. Among them, an immune function is the most plausible based on our experimental results. In summary, our study indicates that although Ccn3 is strongly expressed in Type III taste cells, its knockout did not influence the basic taste response, but bioinformatics provided valuable insights into the possible role of Ccn3 in taste buds and shed light on future research directions. en-copyright= kn-copyright= en-aut-name=WangKuanyu en-aut-sei=Wang en-aut-mei=Kuanyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MitohYoshihiro en-aut-sei=Mitoh en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HorieKengo en-aut-sei=Horie en-aut-mei=Kengo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YoshidaRyusuke en-aut-sei=Yoshida en-aut-mei=Ryusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Oral Physiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Oral Physiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral Physiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Oral Physiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=bioinformatics kn-keyword=bioinformatics en-keyword=Ccn3 kn-keyword=Ccn3 en-keyword=Type III taste cell kn-keyword=Type III taste cell END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=1 article-no= start-page=JAMDSM0001 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=2025 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Development of tool life prediction system for square end-mills based on database of servo motor current value en-subtitle= kn-subtitle= en-abstract= kn-abstract=Accurate prediction of tool life is crucial for reducing production costs and enhancing quality in the machining process. However, such predictions often rely on empirical knowledge, which may limit inexperienced engineers to reliably obtain accurate predictions. This study explores a method to predict the tool life of a cutting machine using servo motor current data collected during the initial stages of tool wear, which is a cost-effective approach. The LightGBM model was identified as suitable for predicting tool life from current data, given the challenges associated with predicting from the average variation of current values. By identifying and utilizing the top 50 features from the current data for prediction, the accuracy of tool life prediction in the early wear stage improved. As this prediction method was developed based on current data obtained during the very early wear stage in experiments with square end-mills, it was tested on extrapolated data using different end-mill diameters. The findings revealed average accuracy rates of 71.2% and 69.4% when using maximum machining time and maximum removal volume as thresholds, respectively. en-copyright= kn-copyright= en-aut-name=KODAMAHiroyuki en-aut-sei=KODAMA en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SUZUKIMakoto en-aut-sei=SUZUKI en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OHASHIKazuhito en-aut-sei=OHASHI en-aut-mei=Kazuhito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate school of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Milling kn-keyword=Milling en-keyword=LightGBM kn-keyword=LightGBM en-keyword=Tool life prediction kn-keyword=Tool life prediction en-keyword=Square end-mill kn-keyword=Square end-mill en-keyword=Servo motor current kn-keyword=Servo motor current END start-ver=1.4 cd-journal=joma no-vol=222 cd-vols= no-issue= article-no= start-page=115374 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Environmental water in Kolkata is suitable for the survival of Vibrio cholerae O1 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Many patients with cholera emerge in Kolkata, India throughout the year. Such emergency indicates that cholera toxin-producing Vibrio cholerae O1 (toxigenic V. cholerae O1) are widespread in Kolkata. This suggests that the suitable conditions for replication of toxigenic V. cholerae O1 is provided in Kolkata. In previous studies, we found that the replication rate of toxigenic V. cholerae O1 is low in the low ionic aqueous solution. Then we measured the ion concentration in the environmental water of Kolkata. As a control, we measured them in Japanese environmental water. The ion concentration in the environmental water of Kolkata was significantly high. Then, we examined the survival of toxigenic V. cholerae O1 in groundwater from Kolkata and found that V. cholerae O1 survive for long time in the solution but not in the solution diluted with Milli Q water. In addition, we found that V. cholerae O1 proliferated in environmental water of Kolkata to which a small amount of nutrient was added, but did not grow in the environmental water diluted with water to which the same amount of nutrient was added. These results indicate that the environmental water from Kolkata is suitable for survival of V. cholerae O1. en-copyright= kn-copyright= en-aut-name=TakahashiEizo en-aut-sei=Takahashi en-aut-mei=Eizo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KitaharaKei en-aut-sei=Kitahara en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyoshiShin-ichi en-aut-sei=Miyoshi en-aut-mei=Shin-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ChowdhuryGoutam en-aut-sei=Chowdhury en-aut-mei=Goutam kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MukhopadhyayAsish K. en-aut-sei=Mukhopadhyay en-aut-mei=Asish K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=DuttaShanta en-aut-sei=Dutta en-aut-mei=Shanta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OchiSadayuki en-aut-sei=Ochi en-aut-mei=Sadayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OkamotoKeinosuke en-aut-sei=Okamoto en-aut-mei=Keinosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Collaborative Research Center of Okayama University for Infectious Diseases in India kn-affil= affil-num=2 en-affil=Collaborative Research Center of Okayama University for Infectious Diseases in India kn-affil= affil-num=3 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences of Okayama University kn-affil= affil-num=4 en-affil=National Institute of Cholera and Enteric Diseases kn-affil= affil-num=5 en-affil=National Institute of Cholera and Enteric Diseases kn-affil= affil-num=6 en-affil=National Institute of Cholera and Enteric Diseases kn-affil= affil-num=7 en-affil=Department of Health Pharmacy, Yokohama University of Pharmacy kn-affil= affil-num=8 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences of Okayama University kn-affil= en-keyword=Environmental water kn-keyword=Environmental water en-keyword=Ion kn-keyword=Ion en-keyword=Prevalence kn-keyword=Prevalence en-keyword=Survival kn-keyword=Survival en-keyword=Vibrio cholerae kn-keyword=Vibrio cholerae END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue=3 article-no= start-page=100105 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202412 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Capturing chronological variation in L2 speech through lexical measurements and regression analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study aims to bridge gaps in current research by analyzing a longitudinal spoken learner corpus of low-proficiency English learners. We investigated the chronological variation in lexical measurements in second language (L2) speaking production, focusing on data from 104 low-proficiency learners elicited eight times over 23 months. Our findings show that measures such as the number of different words and type-token ratio are effective indicators of L2 speaking development, whereas the use of sophisticated vocabulary was not significantly correlated with learning duration. These results suggest that in the early stages of L2 acquisition, speaking skills are influenced primarily by lexical variation. This finding underscores the importance of lexical variation as a key factor in novice-level L2 speaking proficiency. en-copyright= kn-copyright= en-aut-name=AbeMariko en-aut-sei=Abe en-aut-mei=Mariko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KobayashiYuichiro en-aut-sei=Kobayashi en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KondoYusuke en-aut-sei=Kondo en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Okayama University kn-affil= affil-num=2 en-affil=Nihon University kn-affil= affil-num=3 en-affil=Waseda University kn-affil= en-keyword=Longitudinal learner corpus kn-keyword=Longitudinal learner corpus en-keyword=Second language speaking kn-keyword=Second language speaking en-keyword=Low-proficiency learner kn-keyword=Low-proficiency learner en-keyword=Automatic analyzer kn-keyword=Automatic analyzer en-keyword=Regression analysis kn-keyword=Regression analysis END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=1 article-no= start-page=48 end-page=53 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241209 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effectiveness of oral health care intervention for stroke patients following the introduction of Oral Health Assessment Tool en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aim: This study aimed to evaluate the effectiveness of oral health assessment tools in facilitating oral health care interventions by dental care providers for acute stroke patients within 48?h of admission, following a reform of the nursing system.

Methods: Participants were 45,233 older adults aged 75 and over living in Kure City, Japan. In addition to the government-mandated health checkup items, the Intervention group underwent additional risk screening tests included questionnaires, physical examinations, blood tests, and educational guidance by nurses. The efficacy of the intervention was examined whether there were differences in the number of hospitalizations, the use of emergency and critical care, and the incidence of hemodialysis induction between the Intervention and control groups (Usual Health Checkup group and No Health Checkup group) for the 2 years.
Results: There were 485 participants in the Intervention group, 1,067 in the Usual Health Checkup group, and 43,712 in the No Health Checkup group. As the risks of seven diseases in the Intervention group, the largest proportion of deviations occurred for systolic blood pressure (63.3%), estimated salt intake (60.3%), and low-density lipoprotein cholesterol (51.5%). Estimated glomerular filtration rate deviated in 41.0%, N-terminal pro b-type natriuretic peptide in 37.9%. 7.5% scored <2 points on the Mini-Cog (c), and 9.1% performed the Timed Up and Go test in >12 s. The incidence of hospitalization due to any of the seven diseases was significantly higher in the No Health Checkup group (p < 0.001). There were no differences among the three groups in the use of emergency and critical care or the introduction of hemodialysis.
Conclusion: This study revealed that additional health checkup tests and intervention methods could be prevented hospitalization among the adults of 75 years and older. It is necessary to make health checkups and follow-ups more accessible those are already available within the existing health system in Japan. en-copyright= kn-copyright= en-aut-name=KazawaKana en-aut-sei=Kazawa en-aut-mei=Kana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawaiMadoka en-aut-sei=Kawai en-aut-mei=Madoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MoriyamaMichiko en-aut-sei=Moriyama en-aut-mei=Michiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Division of Nursing Science, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=3 en-affil=Division of Nursing Science, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= en-keyword=older adults kn-keyword=older adults en-keyword=health checkups kn-keyword=health checkups en-keyword=health risk kn-keyword=health risk en-keyword=hospitalization kn-keyword=hospitalization en-keyword=education kn-keyword=education END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=6 article-no= start-page=475 end-page=483 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202412 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=C-arm Free Unilateral Biportal Endoscopic Discectomy: A Technical Note en-subtitle= kn-subtitle= en-abstract= kn-abstract=This report presents a new unilateral biportal endoscopic (UBE) technique for lumbar disc herniation without C-arm guidance. Lumbar disc herniation requires surgical intervention when conservative methods fail. Shifts towards minimally invasive percutaneous endoscopic lumbar discectomy, including uniportal and biportal approaches, have been hindered by challenges such as steep learning curves and reliance on radiation-intensive C-arm guidance. We here describe the use of standard intraoperative navigation in UBE to reduce radiation exposure and increase surgical accuracy. A 24-year-old man with low back and bilateral leg pain with gait disturbance was referred to our hospital. He had had conservative treatment for 12 months in another hospital before admission, but this proved unsuccessful. On admission he had low back pain (VAS 4/10) and bilateral leg pain (VAS 8/10), muscle weakness of the bilateral legs (manual muscle testing (MMT) grade of the extensor hallucis longus: 4/4), and numbness of the bilateral lower legs. Preoperative lumbar MRI showed L4/5 large central disc herniation. He underwent C-arm free UBE discectomy under the guidance of O-arm navigation. The surgery was successful, with postoperative lumbar MRI showing good decompression of the dural sac and bilateral L5 nerve roots. The MMT grade and sensory function of both legs had recovered fully on final follow-up at one year. The new UBE technique under navigation guidance was shown to be useful for lumbar disc herniation. This innovative technique was safe and accurate for the treatment of lumbar intervertebral disc herniation, and minimized radiation exposure to surgeons. en-copyright= kn-copyright= en-aut-name=XiangHongfei en-aut-sei=Xiang en-aut-mei=Hongfei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LatkaKajetan en-aut-sei=Latka en-aut-mei=Kajetan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MastePraful en-aut-sei=Maste en-aut-mei=Praful kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaMasato en-aut-sei=Tanaka en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KumawatChetan en-aut-sei=Kumawat en-aut-mei=Chetan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AratakiShinya en-aut-sei=Arataki en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FujiwaraYoshihiro en-aut-sei=Fujiwara en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TaokaTakuya en-aut-sei=Taoka en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MiyamotoAkiyoshi en-aut-sei=Miyamoto en-aut-mei=Akiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=9 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= en-keyword=lumbar disc herniation kn-keyword=lumbar disc herniation en-keyword=unilateral biportal endoscopic technique kn-keyword=unilateral biportal endoscopic technique en-keyword=navigation kn-keyword=navigation en-keyword=O-arm kn-keyword=O-arm en-keyword=minimally invasive spine surgery (MISS) kn-keyword=minimally invasive spine surgery (MISS) END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=6 article-no= start-page=439 end-page=447 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202412 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Risk Factors for Gangrenous Cholecystitis and the Outcomes of Early Cholecystectomy: A Retrospective Study of a Single-Center City General Hospital en-subtitle= kn-subtitle= en-abstract= kn-abstract=Gangrenous cholecystitis (GC) is classified as moderate acute cholecystitis according to the Tokyo Guidelines from 2018 (TG18). We evaluated the risk factors for GC and the outcomes of early cholecystectomy. A total of 136 patients who underwent emergency cholecystectomy for acute cholecystitis were retrospectively analyzed; 58 of these patients (42.6%) were diagnosed with GC (GC group) based on our retrospective pathologic diagnosis. We comparatively evaluated the patient backgrounds and surgical outcomes between the GC group and non-GC group. The GC group was significantly older and included more hypertensive patients than the non-GC group. The GC group was prescribed more antibiotics as initial treatment than the non-GC group, and they had more days between onset and surgery. The preoperative white blood cell count and C-reactive protein values were significantly higher in the GC group than in the non-GC group, and these values were predictive factors for GC. Cholecystectomy required a longer operation time and caused greater blood loss in the GC group. The GC group also had longer hospitalization times than the non-GC group; however, no significant differences were observed in terms of postoperative complications. In conclusion, gangrenous changes should be assessed when diagnosing cholecystitis, and appropriate treatment, such as surgery or drainage, should be undertaken. en-copyright= kn-copyright= en-aut-name=YamashitaMampei en-aut-sei=Yamashita en-aut-mei=Mampei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaTakayuki en-aut-sei=Tanaka en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SumidaYorihisa en-aut-sei=Sumida en-aut-mei=Yorihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamazakiShoto en-aut-sei=Yamazaki en-aut-mei=Shoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HaraYuki en-aut-sei=Hara en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FukudaAkiko en-aut-sei=Fukuda en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HisanagaMakoto en-aut-sei=Hisanaga en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=WakataKoki en-aut-sei=Wakata en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ArakiMasato en-aut-sei=Araki en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=EguchiSusumu en-aut-sei=Eguchi en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Surgery, Sasebo City General Hospital kn-affil= affil-num=2 en-affil=Department of Surgery, Sasebo City General Hospital kn-affil= affil-num=3 en-affil=Department of Surgery, Sasebo City General Hospital kn-affil= affil-num=4 en-affil=Department of Surgery, Sasebo City General Hospital kn-affil= affil-num=5 en-affil=Department of Surgery, Sasebo City General Hospital kn-affil= affil-num=6 en-affil=Department of Surgery, Sasebo City General Hospital kn-affil= affil-num=7 en-affil=Department of Surgery, Sasebo City General Hospital kn-affil= affil-num=8 en-affil=Department of Surgery, Sasebo City General Hospital kn-affil= affil-num=9 en-affil=Department of Surgery, Sasebo City General Hospital kn-affil= affil-num=10 en-affil=Department of Surgery, Nagasaki University Graduate School of Biomedical Science kn-affil= en-keyword=gangrenous kn-keyword=gangrenous en-keyword=cholecystitis kn-keyword=cholecystitis en-keyword=acute cholecystitis kn-keyword=acute cholecystitis en-keyword=laparoscopic cholecystectomy kn-keyword=laparoscopic cholecystectomy END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue= article-no= start-page=1468230 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241206 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Perspectives of traditional herbal medicines in treating retinitis pigmentosa en-subtitle= kn-subtitle= en-abstract= kn-abstract=Medicinal plants, also known as herbs, have been discovered and utilized in traditional medical practice since prehistoric times. Medicinal plants have been proven rich in thousands of natural products that hold great potential for the development of new drugs. Previously, we reviewed the types of Chinese traditional medicines that a Tang Dynasty monk Jianzhen (Japanese: Ganjin) brought to Japan from China in 742. This article aims to review the origin of Kampo (Japanese traditional medicine), and to present the overview of neurodegenerative diseases and retinitis pigmentosa as well as medicinal plants in some depth. Through the study of medical history of the origin of Kampo, we found that herbs medicines contain many neuroprotective ingredients. It provides us a new perspective on extracting neuroprotective components from herbs medicines to treat neurodegenerative diseases. Retinitis pigmentosa (one of the ophthalmic neurodegenerative diseases) is an incurable blinding disease and has become a popular research direction in global ophthalmology. To date, treatments for retinitis pigmentosa are very limited worldwide. Therefore, we intend to integrate the knowledge and skills from different disciplines, such as medical science, pharmaceutical science and plant science, to take a new therapeutic approach to treat neurodegenerative diseases. In the future, we will use specific active ingredients extracted from medicinal plants to treat retinitis pigmentosa. By exploring the potent bioactive ingredients present in medicinal plants, a valuable opportunity will be offered to uncover novel approaches for the development of drugs which target for retinitis pigmentosa. en-copyright= kn-copyright= en-aut-name=LiuShihui en-aut-sei=Liu en-aut-mei=Shihui kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsuoChie en-aut-sei=Matsuo en-aut-mei=Chie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AbeTakumi en-aut-sei=Abe en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ChenJinghua en-aut-sei=Chen en-aut-mei=Jinghua kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SunChi en-aut-sei=Sun en-aut-mei=Chi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ZhaoQing en-aut-sei=Zhao en-aut-mei=Qing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Ophthalmology, University of Florida, College of Medicine kn-affil= affil-num=6 en-affil=Department of Ophthalmology and Visual Sciences, Washington University in St. Louis kn-affil= affil-num=7 en-affil=National Key Laboratory of Plant Molecular Genetics, CAS Center for Excellence in Molecular Plant Sciences, Shanghai Institute of Plant Physiology and Ecology, Chinese Academy of Sciences kn-affil= en-keyword=retinitis pigmentosa kn-keyword=retinitis pigmentosa en-keyword=ophthalmology kn-keyword=ophthalmology en-keyword=botany kn-keyword=botany en-keyword=pharmacology kn-keyword=pharmacology en-keyword=medical history kn-keyword=medical history en-keyword=compound kn-keyword=compound en-keyword=drug discovery kn-keyword=drug discovery en-keyword=degenerative diseases kn-keyword=degenerative diseases END start-ver=1.4 cd-journal=joma no-vol=67 cd-vols= no-issue=2 article-no= start-page=189 end-page=195 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=2023 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Prosthodontic treatment can improve the ingestible food profile in Japanese adult outpatients en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose: To investigate the effect of prosthodontic treatment on the ingestible food profile in adult Japanese outpatients, and to identify the related risk factors that can deteriorate the profile.
Methods: The participants were 277 outpatients who visited university-based specialty clinics in Japan for prosthodontic treatment. The demographic data, number of present teeth assessed via intraoral examination, and oral health-related quality of life assessed by the total Oral Health Impact Profile (OHIP-J54) scores of all participants were recorded before treatment. Ingestible food profile score (IFS) was recorded using a validated food intake questionnaire. Eligible participants who answered the questionnaire before and after treatment were categorized into five groups based on the prosthodontic treatments they received (i.e., crowns, bridges, removable partial dentures, removable complete dentures, and removable complete and partial dentures).
Results: Multivariate analysis of covariance revealed a statistically significant main effect of prosthodontic intervention (time course: before and after treatment) on mean IFS (P=0.035, F=4.526), even after adjusting for covariates (age, number of present teeth, and treatment modality). Multiple linear regression analysis revealed that the low number of present teeth (r=0.427, P<0.001) and a high OHIP-J54 total score (r=-0.519, P<0.001) of the patients at the baseline were significantly associated with their baseline IFSs, even after adjusting for confounding variables.
Conclusions: The findings of this multicenter follow-up study indicate the importance of prosthodontic rehabilitation in improving patients’ ingestible food profiles. en-copyright= kn-copyright=

en-abstract= kn-abstract=The discovery of new antimalarial drugs can be developed using asynchronized Plasmodium berghei malaria parasites in vivo in mice. Studies on a particular stage are also required to assess the effectiveness and mode of action of drugs. In this report, we used endoperoxide 6-(1,2,6,7-tetraoxaspiro [7.11] nonadec-4-yl) hexan-1-ol (N-251) as a model antimalarial compound on P. chabaudi parasites. We examined the antimalarial effect of N-251 against ring-stage- and trophozoite-stage-rich P. chabaudi parasites and asynchronized P. berghei parasites using the 4-day suppressive test. The ED50 values were 27, 22, and 22 mg/kg, respectively, and the antimalarial activity of N-251 was verified in both rodent malaria parasites. To assess the stage-specific effect of N-251 in vivo, we evaluated the change of parasitemia and distribution of parasite stages using ring-stage- and trophozoite-stage-rich P. chabaudi parasites with one-day drug administration for one life cycle. We discovered that the parasitemias decreased after 13 and 9 hours post-treatment in the ring-stage- and trophozoite-stage-rich groups, respectively. Additionally, in the ring-stage-rich N-251 treated group, the ring-stage parasites hindered trophozoite parasite development. For the trophozoite-stage-rich N-251 treated group, the distribution of the trophozoite stage was maintained without a change in parasitemia until 9 hours. Because of these findings, it can be concluded that N-251 suppressed the trophozoite stage but not the ring stage. We report for the first time that N-251 specifically suppresses the trophozoite stage using P. chabaudi in mice. The results show that P. chabaudi is a reliable model for the characterization of stage-specific antimalarial effects. en-copyright= kn-copyright= en-aut-name=AlyNagwa S.

We have been conducting CKD public education programs in Okayama Prefecture since 2007. Here, we aimed to examine the actual status of CKD perceptance and changes in CKD perceptance due to these education programs. The study was conducted on individuals who underwent health checkups at 12 medical institutions across five medical regions in Okayama Prefecture between 1 October and 30 November in 2015, 2019, and 2023. The results showed that overall CKD perceptance has improved over time (perceptance of "CKD" 4% to 7%, "chronic kidney disease" 27% to 34%, 2015 vs. 2023). "Chronic kidney disease" was more commonly recognized than "CKD", and the elderly were more aware of the disease than younger people. The CKD perceptance improved across all age groups. However, the rate of CKD perceptance is still low, especially among young people. Previously, newspapers were the second most common resource of information about CKD after television. However, the Internet has recently replaced newspapers as the second most common source of information, especially among younger people. Understanding of the exact diagnosis of CKD also remains insufficient. It is necessary to continue more effective CKD public education programs through more intelligible terminology and information sources that match the demographics of target population. en-copyright= kn-copyright= en-aut-name=UmebayashiRyoko en-aut-sei=Umebayashi en-aut-mei=Ryoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Matsuoka-UchiyamaNatsumi en-aut-sei=Matsuoka-Uchiyama en-aut-mei=Natsumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SugiyamaHitoshi en-aut-sei=Sugiyama en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ShikataKenichi en-aut-sei=Shikata en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KashiharaNaoki en-aut-sei=Kashihara en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MakinoHirofumi en-aut-sei=Makino en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UchidaHaruhito A. en-aut-sei=Uchida en-aut-mei=Haruhito A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Okayama University kn-affil= affil-num=5 en-affil=Kawasaki Geriatric Medical Center kn-affil= affil-num=6 en-affil=Okayama University kn-affil= affil-num=7 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=chronic kidney disease kn-keyword=chronic kidney disease en-keyword= CKD perceptance kn-keyword= CKD perceptance en-keyword= CKD public education programs kn-keyword= CKD public education programs END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=2 article-no= start-page=35 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230511 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Development of the Follow-Up Human 3D Oral Cancer Model in Cancer Treatment en-subtitle= kn-subtitle= en-abstract= kn-abstract=As function preservation cancer therapy, targeted radiation therapies have been developed for the quality of life of cancer patients. However, preclinical animal studies evaluating the safety and efficacy of targeted radiation therapy is challenging from the viewpoints of animal welfare and animal protection, as well as the management of animal in radiation-controlled areas under the regulations. We fabricated the human 3D oral cancer model that considers the time axis of the follow up in cancer treatment. Therefore, in this study, the 3D model with human oral cancer cells and normal oral fibroblasts was treated based on clinical protocol. After cancer treatment, the histological findings of the 3D oral cancer model indicated the clinical correlation between tumor response and surrounding normal tissue. This 3D model has potential as a tool for preclinical studies alternative to animal studies. en-copyright= kn-copyright= en-aut-name=IgawaKazuyo en-aut-sei=Igawa en-aut-mei=Kazuyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IzumiKenji en-aut-sei=Izumi en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SakuraiYoshinori en-aut-sei=Sakurai en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Neutron Therapy Research Center, Okayama University kn-affil= affil-num=2 en-affil=Division of Biomimetics, Faculty of Dentistry & Graduate School of Medical and Dental Sciences, Niigata University kn-affil= affil-num=3 en-affil=Institute for Integrated Radiation and Nuclear Science, Kyoto University kn-affil= en-keyword=3D cancer model kn-keyword=3D cancer model en-keyword=preclinical study kn-keyword=preclinical study en-keyword=cancer treatment kn-keyword=cancer treatment en-keyword=quality of life kn-keyword=quality of life en-keyword=multidisciplinary treatment kn-keyword=multidisciplinary treatment END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=3 article-no= start-page=e20220127 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=2023 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Rapid thawing of frozen bull spermatozoa by transient exposure to 70 °C improves the viability, motility and mitochondrial health en-subtitle= kn-subtitle= en-abstract= kn-abstract=Up to now, the definitive conclusion of the positive effects of rapid transient thawing at higher temperatures for shorter durations has not been obtained yet and is still under discussion due to some contradictory findings and limited assessment of post-thawed parameters. The purpose of the current study was to evaluate the effectiveness of rapid thawing in water at 70 °C by using various post-thawed parameters of frozen bull spermatozoa. Experiment 1, monitoring the change of temperature inside frozen bull straw thawed in water at different temperatures. Experiment 2, evaluation of various post-thawed characteristics of frozen bull spermatozoa thawed in water at different temperatures by using a computer-assisted sperm analysis, flow cytometry and immunocytochemistry. The time it took for the temperature inside the straw to warm up to 15 °C was nearly twice as faster when the straw was thawed in 70 °C water compared with 39 °C. Although there were differences among bulls, viability, motility, and mitochondrial membrane potential of spermatozoa thawed at 70 °C for 8 seconds and stabilized at 39 °C for 52 seconds were significantly higher than those of controls (thawed at 39 °C for 60 seconds) at 0 and 3 h after thawing. Just after thawing, however, there were no differences in acrosome integrity and distribution of phospholipase C zeta1, whereas mitochondrial reactive oxygen species production was significantly lower in spermatozoa thawed at 70 °C. From these results, we conclude that rapid thawing at 70 °C and then stabilization at 39 °C significantly improves viability, motility and mitochondrial health of bull spermatozoa rather than conventional thawing at 39 °C. The beneficial effect of rapid transient thawing could be due to shorter exposure to temperatures outside the physiological range, consequently maintaining mitochondrial health. en-copyright= kn-copyright= en-aut-name=NguyenHai Thanh en-aut-sei=Nguyen en-aut-mei=Hai Thanh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DoSon Quang en-aut-sei=Do en-aut-mei=Son Quang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AthurupanaRukmali en-aut-sei=Athurupana en-aut-mei=Rukmali kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WakaiTakuya en-aut-sei=Wakai en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FunahashiHiroaki en-aut-sei=Funahashi en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=bull semen kn-keyword=bull semen en-keyword=cryopreservation process kn-keyword=cryopreservation process en-keyword=phospholipase C zeta1 (PLCZ1) kn-keyword=phospholipase C zeta1 (PLCZ1) en-keyword=temperature of thawing kn-keyword=temperature of thawing END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page=366 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241120 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The required experience of open pancreaticoduodenectomy before becoming a specialist in hepatobiliary and pancreatic surgeons: a multicenter, cohort study of 334 open pancreaticoduodenectomies en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Open pancreaticoduodenectomy (OPD) is an essential surgical procedure for expert hepato-biliary-pancreatic (HBP) surgeons. However, there is no standard for how many surgeries must be performed by a surgeon in training before they are considered to have enough experience to ensure surgical safety.
Methods Cumulative Sum (CUSUM) analysis was performed using the surgical data of OPDs performed during the training period of board-certified expert surgeons of the Japanese Society of Hepato-Biliary-Pancreatic Surgery.
Results Fourteen HBP surgeons participated in this study and performed 334 OPDs during their training period. The median (interquartile range) values for operative time, blood loss, and length of hospital stay were 455 (397-519) minutes, 450 (234--716) ml, and 28 (21-38) days, respectively. CUSUM analysis showed inflection points at 20 surgeries performed for operative time. After 20 procedures, operative time was significantly shorter (461 min vs. 425 min, p = 0.021) and blood loss was significantly lower (470 ml vs. 340 ml, p = 0.038). No significant differences between within 20 and after 21 procedures were found in the complication rate (53% vs. 48%, p = 0.424) and rate of in-hospital deaths (1.5% vs.1.4%. p = 0.945). Up to 20 surgeries, PDAC and another malignant tumor had longer operative time than benign/low malignant diseases (486 min vs. 472 min vs. 429 min, p < 0.001), and higher blood loss (500 ml vs. 502 ml vs. 355 ml, p < 0.001). Mortality rate was higher at PDAC cases (5% vs. 0% vs. 0%, p = 0.01). After the 21 procedures, these outcomes were improved and no differences in by primary disease were observed. Multivariable analysis showed that within 20 surgeries were independent risk factors of longer operative time (HR2.6, p = 0.013) and higher blood loss (HR2.0, p = 0.049).
Conclusions To stabilize the surgical outcome of OPD for malignant disease, at least 20 surgeries should be performed at a certified institution during surgeon training.

The current study investigates time‐to‐event outcomes at 8?years.
Methods and Results: This cohort enrolled patients with single ventricles who underwent stage 2 or stage 3 palliation from January 2011 to January 2015 at 8 centers in Japan. The primary outcomes were time‐dependent CDC treatment effects on death and late complications during 8?years of follow‐up, assessed by restricted mean survival time. Among 93 patients enrolled (mean age, 2.3±1.3?years; 56% men), 40 received CDC infusion. Overall survival for CDC‐treated versus control patients did not differ at 8?years (hazard ratio [HR], 0.60 [95% CI, 0.21?1.77]; P=0.35). Treatment effect had nonproportional hazards for death favoring CDCs at 4?years (restricted mean survival time difference +0.33?years [95% CI, 0.01?0.66]; P=0.043). In patients with heart failure with reduced ejection fraction, CDC treatment effect on survival was greater over 8?years (restricted mean survival time difference +1.58?years [95% CI, 0.05?3.12]; P=0.043). Compared with control participants, CDC‐treated patients showed lower incidences of late failure (HR, 0.45 [95% CI, 0.21?0.93]; P=0.027) and adverse events (subdistribution HR, 0.50 [95% CI, 0.27?0.94]; P=0.036) at 8?years.
Conclusions: By 8?years, CDC infusion was associated with lower hazards of late failure and adverse events in single ventricle heart disease. CDC treatment effect on survival was notable by 4?years and showed a durable clinical benefit in patients with heart failure with reduced ejection fraction over 8?years.

In the budding yeast Saccharomyces cerevisiae, a variety of constitutive and controllable promoters with different strengths have been constructed using endogenous gene promoters, synthetic transcription factors and their binding sequences, and artificial sequences. However, there have been no attempts to construct the highest strength promoter in yeast cells. In this study, by incrementally increasing the binding sequences of the synthetic transcription factor Z3EV, we were able to construct a promoter (P36) with ~1.4 times the strength of the TDH3 promoter. This is stronger than any previously reported promoter. Although the P36 promoter exhibits some leakage in the absence of induction, the expression induction by estradiol is maintained. When combined with a multicopy plasmid, it can express up to ~50% of total protein as a heterologous protein. This promoter system can be used to gain knowledge about the cell physiology resulting from the ultimate overexpression of excess proteins and is expected to be a useful tool for heterologous protein expression in yeast. en-copyright= kn-copyright= en-aut-name=HiguchiRina en-aut-sei=Higuchi en-aut-mei=Rina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujitaYuri en-aut-sei=Fujita en-aut-mei=Yuri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NambaShotaro en-aut-sei=Namba en-aut-mei=Shotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoriyaHisao en-aut-sei=Moriya en-aut-mei=Hisao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=yeast kn-keyword=yeast en-keyword=overexpression kn-keyword=overexpression en-keyword=promoter kn-keyword=promoter END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=1 article-no= start-page=53 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241102 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of systemic ventricular assist in failing Fontan patients: a theoretical analysis using a computational model en-subtitle= kn-subtitle= en-abstract= kn-abstract=Mechanical circulatory support is a potential treatment for failing Fontan patients. In this study, we performed a theoretical analysis using a computational model to clarify the effects of systemic ventricular assist device (VAD) in failing Fontan patients. Cardiac chambers and vascular systems were described using the time-varying elastance model and modified Windkessel model, respectively. A VAD was simulated as a nonlinear function. In systolic and diastolic ventricular dysfunction and atrioventricular valve regurgitation models, systemic VAD increased the cardiac index and decreased the central venous pressure (CVP). However, in the high pulmonary vascular resistance model, CVP became extremely high above 15 mmHg to maintain the cardiac index when the pulmonary vascular resistance index (PVRI) was above 5 Wood units m2. In Fontan patients with ventricular dysfunction or atrioventricular valve regurgitation, systemic VAD efficiently improves the hemodynamics. In Fontan patients with PVRI of?>?5 Wood units m2, systemic VAD seems ineffective. en-copyright= kn-copyright= en-aut-name=KisamoriEiri en-aut-sei=Kisamori en-aut-mei=Eiri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KotaniYasuhiro en-aut-sei=Kotani en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShishidoToshiaki en-aut-sei=Shishido en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KasaharaShingo en-aut-sei=Kasahara en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShimizuShuji en-aut-sei=Shimizu en-aut-mei=Shuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences and Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences and Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Research Promotion and Management, National Cerebral and Cardiovascular Center kn-affil= affil-num=4 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences and Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences and Okayama University Hospital kn-affil= en-keyword=Ventricular assist device kn-keyword=Ventricular assist device en-keyword=Failing Fontan kn-keyword=Failing Fontan en-keyword=Hemodynamic simulation kn-keyword=Hemodynamic simulation en-keyword=Lumped parameter model kn-keyword=Lumped parameter model END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=10 article-no= start-page=614 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241007 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=An Independent Learning System for Flutter Cross-Platform Mobile Programming with Code Modification Problems en-subtitle= kn-subtitle= en-abstract= kn-abstract=Nowadays, with the common use of smartphones in daily lives, mobile applications have become popular around the world, which will lead to a rise in Flutter framework. Developed by Google, Flutter with Dart programming provides a cross-platform development environment to create visually appealing and responsive user interfaces across mobile, web, and desktop platforms using a single codebase. However, due to time and staff limitations, the Flutter/Dart programming course is not included in curricula, even in IT departments in universities. Therefore, independent learning environments for students are essential to meet this growing popularity. Previously, we have developed programming learning assistant system (PLAS) as a web-browser-based self-learning platform for novice students. PLAS offers various types of exercise problems designed to cultivate programming skills step-by-step through a lot of code reading and code writing practices. Among them, one particular type is the code modification problem (CMP), which asks to modify the given source code to satisfy the new specifications. CMP is expected to be solved by novices with little effort if they have knowledge of other programming languages. Thus, PLAS with CMP will be an excellent platform for independent learning. In this paper, we present PLAS with CMP for the independent learning of Flutter/Dart programming. To improve the readability of the source code by students, we provided rich comments on grammar or behaviors. Besides, the code can be downloaded so that students can check and run it on an IDE. For evaluations, we generated 38 CMP instances for basic and multimedia/storage topics in Flutter/Dart programming and assigned them to 21 master students at Okayama University, Japan, who have never studied it. The results confirm the validity of the proposal. en-copyright= kn-copyright= en-aut-name=KinariSafira Adine en-aut-sei=Kinari en-aut-mei=Safira Adine kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FunabikiNobuo en-aut-sei=Funabiki en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AungSoe Thandar en-aut-sei=Aung en-aut-mei=Soe Thandar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WaiKhaing Hsu en-aut-sei=Wai en-aut-mei=Khaing Hsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MentariMustika en-aut-sei=Mentari en-aut-mei=Mustika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=PuspitaningayuPradini en-aut-sei=Puspitaningayu en-aut-mei=Pradini kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Department of Electrical Engineering, Universitas Negeri Surabaya kn-affil= en-keyword=Flutter kn-keyword=Flutter en-keyword=Dart kn-keyword=Dart en-keyword=cross-platform kn-keyword=cross-platform en-keyword=programming kn-keyword=programming en-keyword=code modification problem kn-keyword=code modification problem en-keyword=PLAS kn-keyword=PLAS en-keyword=independent learning kn-keyword=independent learning END start-ver=1.4 cd-journal=joma no-vol=30 cd-vols= no-issue=12 article-no= start-page=1324 end-page=1326 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202412 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Detailed regimens for the prolonged β-lactam infusion therapy en-subtitle= kn-subtitle= en-abstract= kn-abstract=A recent systematic review and meta-analysis of randomized controlled trials (RCTs) evaluated the efficacy and safety of prolonged versus intermittent β-lactam infusion in adult sepsis patients. The findings revealed a significant decrease in all-cause mortality and marked clinical success in the prolonged infusion group. Unfortunately, however, the manuscript lacked data and discussion for the specific regimens of prolonged β-lactam infusion defined in the included 15 RCT studies, which are herein additionally provided. Excluding one RCT, all protocols adopted a continuous infusion for the prolonged treatment. Except for three RCTs, dosages and timings of bolus injection were clearly defined. The total daily antibiotic dose for the continuous therapy was equivalent to those recommended for intermittent therapy. We believe this supplementary data aids clinicians in providing prolonged β-lactam infusions, contributing to enhanced treatment outcomes for patients suffering from severe sepsis or septic shock. en-copyright= kn-copyright= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= en-keyword=Sepsis kn-keyword=Sepsis en-keyword=Continuous infusion kn-keyword=Continuous infusion en-keyword=Prolonged infusion kn-keyword=Prolonged infusion en-keyword=Pharmacokinetics kn-keyword=Pharmacokinetics END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=1 article-no= start-page=23886 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241012 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Perioperative gum-chewing training prevents a decrease in tongue pressure after esophagectomy in thoracic esophageal cancer patients: a nonrandomized trial en-subtitle= kn-subtitle= en-abstract= kn-abstract=Tongue pressure (TP) decreases significantly after esophagectomy in esophageal cancer patients (ECPs). Meanwhile, 2 weeks of gum-chewing training (GCT) significantly increased TP in healthy university students. We examined whether perioperative GCT would decrease the proportion of patients exhibiting a decline in TP at 2 weeks postoperatively, and prevent postoperative complications, in thoracic ECPs (TECPs). This was a single-center interventional study, and nonrandomized study with a historical control group (HCG). TECPs who underwent first-stage radical esophagectomy were recruited. Thirty-two patients of 40 in the gum-chewing group (GCG) were completed perioperative GCT in 3 times daily. Propensity score matching was performed with covariates related to TP including preoperative age, sex, body mass index, and the repetitive saliva swallowing test result, and yielded a matched cohort of 25 case pairs. Eleven GCG patients [44.0%] exhibited significantly lower TP at 2 weeks postoperatively than before esophagectomy was significantly fewer than that of 19 patients [76.0%] in the HCG. The median number of fever days (> 38 degrees C) in the 2 weeks after esophagectomy in the GCG was significantly fewer than those in the HCG. Perioperative GCT may prevent postoperative TP decline and postoperative dysphagia-related complications after esophagectomy. en-copyright= kn-copyright= en-aut-name=Yamanaka-KohnoReiko en-aut-sei=Yamanaka-Kohno en-aut-mei=Reiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShirakawaYasuhiro en-aut-sei=Shirakawa en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YokoiAya en-aut-sei=Yokoi en-aut-mei=Aya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MaedaNaoaki en-aut-sei=Maeda en-aut-mei=Naoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanabeShunsuke en-aut-sei=Tanabe en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NomaKazuhiro en-aut-sei=Noma en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ShimizuKazuyoshi en-aut-sei=Shimizu en-aut-mei=Kazuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MituhashiToshiharu en-aut-sei=Mituhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakamuraYoshihide en-aut-sei=Nakamura en-aut-mei=Yoshihide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NanbaSouto en-aut-sei=Nanba en-aut-mei=Souto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=UchidaYurika en-aut-sei=Uchida en-aut-mei=Yurika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=MaruyamaTakayuki en-aut-sei=Maruyama en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MoritaManabu en-aut-sei=Morita en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=EkuniDaisuke en-aut-sei=Ekuni en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Preventive Dentistry, Division of Dentistry, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=3 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=7 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Oral and Maxillofacial Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=10 en-affil=Dental Clinic, Kurashiki Medical Check-Up Center kn-affil= affil-num=11 en-affil=Department of Preventive Dentistry, Division of Dentistry, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=13 en-affil=Department of Oral Health Sciences, Takarazuka University of Medical and Health Care kn-affil= affil-num=14 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Esophageal cancer kn-keyword=Esophageal cancer en-keyword=Esophagectomy kn-keyword=Esophagectomy en-keyword=Gum-chewing training kn-keyword=Gum-chewing training en-keyword=Tongue pressure kn-keyword=Tongue pressure en-keyword=Historical control kn-keyword=Historical control en-keyword=Propensity score matching analysis kn-keyword=Propensity score matching analysis END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=19 article-no= start-page=5686 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240924 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Liver Transection Area Is a Novel Predictor for Surgical Difficulty in Laparoscopic Liver Resection en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: A difficulty scoring system was developed to estimate the surgical outcomes of laparoscopic liver surgery (LLS); however, the effect of the liver transection area (LTA) on LLS outcomes have not been previously examined. Therefore, this study investigated the predictive significance of the LTA for LLS. Methods: This retrospective study included 106 patients who underwent LLS in our hospital between January 2012 and December 2023. The association of the LTA with the surgical difficulty level and operative time was investigated. Multivariate analyses were performed to identify factors predicting surgical difficulty in LLS. Results: The median LTA and operative time were 62.5 (IQR, 36.0?91.8) cm2 and 250 (IQR, 195?310) minutes, respectively. The LTA was significantly associated with surgical difficulty as evaluated using the IWATE Criteria. Moreover, the LTA significantly correlated with operative time (r2 = 0.19, p < 0.001). The multivariable analyses found that the LTA (?59 cm2) (odds ratio [OR], 6.07; 95% confidence interval [CI], 2.38?16.6; p < 0.001) and the type of LLS (?segmentectomy) (OR, 3.79; 95% CI, 1.35?11.4; p = 0.01) were significant factors associated with surgical difficulty. Conclusions: The LTA is a useful parameter that reflects the difficulty of LLS. en-copyright= kn-copyright= en-aut-name=YamadaMotohiko en-aut-sei=Yamada en-aut-mei=Motohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakagiKosei en-aut-sei=Takagi en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiTomokazu en-aut-sei=Fuji en-aut-mei=Tomokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YasuiKazuya en-aut-sei=Yasui en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KimuraJiro en-aut-sei=Kimura en-aut-mei=Jiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NishiyamaTakeyoshi en-aut-sei=Nishiyama en-aut-mei=Takeyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NagaiYasuo en-aut-sei=Nagai en-aut-mei=Yasuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KanehiraNoriyuki en-aut-sei=Kanehira en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=laparoscopic liver resection kn-keyword=laparoscopic liver resection en-keyword=surgical difficulty kn-keyword=surgical difficulty en-keyword=liver transection area kn-keyword=liver transection area END start-ver=1.4 cd-journal=joma no-vol=39 cd-vols= no-issue=12 article-no= start-page=2760 end-page=2766 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241003 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Rates and risk factors of bleeding after gastric endoscopic submucosal dissection with continuous warfarin or 1‐day withdrawal of direct oral anticoagulants en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and Aim: The 2017 Japanese guidelines recommend continuing warfarin therapy during the perioperative period or discontinuing direct oral anticoagulants (DOACs) only on the day of endoscopic submucosal dissection for early gastric cancer. However, their safety has not been sufficiently explored. This study aimed to validate this management method.
Methods: This retrospective, multicenter study analyzed the characteristics and outcomes of patients who underwent gastric endoscopic submucosal dissection between July 2017 and June 2019. The patients were categorized according to the use of warfarin or DOACs.
Results: Among the 62 eligible patients, 53 (85%) were male (median age, 76 years). Warfarin was used in 10 patients (16%) and DOACs in 52 patients (84%). Fourteen patients taking DOACs (27%) used concomitant antiplatelet agents, with seven patients (13%) continuing treatment at the time of the endoscopic procedure. No postprocedural bleeding occurred in patients receiving warfarin (0%), whereas 10 cases (19%) of bleeding occurred in patients receiving DOACs: rivaroxaban, 0% (0/22); dabigatran, 0% (0/2); edoxaban, 43% (6/14); and apixaban, 29% (4/14). The type of anticoagulant (P < 0.01) and continuation of antiplatelet therapy (P = 0.02) were risk factors for postprocedural bleeding in patients receiving DOACs. Intraprocedural bleeding requiring transfusion or symptomatic thromboembolic events were not reported.
Conclusions: Continuous warfarin therapy is preferred. DOAC withdrawal 1 day before a procedure is associated with a high bleeding rate, which may differ for different types of anticoagulants. The continuation of antiplatelet medications in patients receiving DOACs carries a high risk of bleeding and is a future challenge. en-copyright= kn-copyright= en-aut-name=HirataShoichiro

Pre-Reacted Glass-Ionomer Eluate Suppresses Osteoclastogenesis through Downregulation of the MAPK Signaling Pathway en-subtitle= kn-subtitle= en-abstract= kn-abstract=Surface pre-reacted glass-ionomer (S-PRG) is a new bioactive filler utilized for the restoration of decayed teeth by its ability to release six bioactive ions that prevent the adhesion of dental plaque to the tooth surface. Since ionic liquids are reported to facilitate transepithelial penetration, we reasoned that S-PRG applied to root caries could impact the osteoclasts (OCs) in the proximal alveolar bone. Therefore, this study aimed to investigate the effect of S-PRG eluate solution on RANKL-induced OC-genesis and mineral dissolution in vitro. Using RAW264.7 cells as OC precursor cells (OPCs), TRAP staining and pit formation assays were conducted to monitor OC-genesis and mineral dissolution, respectively, while OC-genesis-associated gene expression was measured using quantitative real-time PCR (qPCR). Expression of NFATc1, a master regulator of OC differentiation, and the phosphorylation of MAPK signaling molecules were measured using Western blotting. S-PRG eluate dilutions at 1/200 and 1/400 showed no cytotoxicity to RAW264.7 cells but did significantly suppress both OC-genesis and mineral dissolution. The same concentrations of S-PRG eluate downregulated the RANKL-mediated induction of OCSTAMP and CATK mRNAs, as well as the expression of NFATc1 protein and the phosphorylation of ERK, JNK, and p38. These results demonstrate that S-PRG eluate can downregulate RANKL-induced OC-genesis and mineral dissolution, suggesting that its application to root caries might prevent alveolar bone resorption. en-copyright= kn-copyright= en-aut-name=ChandraJanaki en-aut-sei=Chandra en-aut-mei=Janaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakamuraShin en-aut-sei=Nakamura en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShindoSatoru en-aut-sei=Shindo en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=LeonElizabeth en-aut-sei=Leon en-aut-mei=Elizabeth kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=CastellonMaria en-aut-sei=Castellon en-aut-mei=Maria kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=PastoreMaria Rita en-aut-sei=Pastore en-aut-mei=Maria Rita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HeidariAlireza en-aut-sei=Heidari en-aut-mei=Alireza kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=WitekLukasz en-aut-sei=Witek en-aut-mei=Lukasz kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=CoelhoPaulo G. en-aut-sei=Coelho en-aut-mei=Paulo G. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NakatsukaToshiyuki en-aut-sei=Nakatsuka en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KawaiToshihisa en-aut-sei=Kawai en-aut-mei=Toshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Oral Science and Translational Research, College of Dental Medicine, Nova Southeastern University kn-affil= affil-num=2 en-affil=Department of Pathophysiology-Periodontal Science, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral Science and Translational Research, College of Dental Medicine, Nova Southeastern University kn-affil= affil-num=4 en-affil=Department of Oral Science and Translational Research, College of Dental Medicine, Nova Southeastern University kn-affil= affil-num=5 en-affil=Department of Oral Science and Translational Research, College of Dental Medicine, Nova Southeastern University kn-affil= affil-num=6 en-affil=Department of Oral Science and Translational Research, College of Dental Medicine, Nova Southeastern University kn-affil= affil-num=7 en-affil=Department of Oral Science and Translational Research, College of Dental Medicine, Nova Southeastern University kn-affil= affil-num=8 en-affil=Biomaterials Division, NYU Dentistry kn-affil= affil-num=9 en-affil=Department of Biochemistry and Molecular Biology, Miller School of Medicine, University of Miami kn-affil= affil-num=10 en-affil=R&D Department, Shofu Inc. kn-affil= affil-num=11 en-affil=Department of Oral Science and Translational Research, College of Dental Medicine, Nova Southeastern University kn-affil= en-keyword=S-PRG kn-keyword=S-PRG en-keyword=osteoclast kn-keyword=osteoclast en-keyword=hydroxyapatite kn-keyword=hydroxyapatite en-keyword=TRAP staining kn-keyword=TRAP staining en-keyword=bioactive filler kn-keyword=bioactive filler END start-ver=1.4 cd-journal=joma no-vol=38 cd-vols= no-issue=1 article-no= start-page=2398895 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=2024 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Surrogate-Assisted Multi-Objective Optimization for Simultaneous Three-Dimensional Packing and Motion Planning Problems Using the Sequence-Triple Representation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Packing problems are classical optimization problems with wide-ranging applications. With the advancement of robotic manipulation, there are growing demands for the automation of packing tasks. However, the simultaneous optimization of packing and the robot's motion planning is challenging because these two decisions are interconnected, and no previous study has addressed this optimization problem. This paper presents a framework to simultaneously determine the robot's motion planning and packing decision to minimize the robot's processing time and the container's volume. This framework comprises three key components: solution encoding, surrogate modeling, and evolutionary computation. The sequence-triple representation encodes complex packing solutions by a sequence of integers. A surrogate model is trained to predict the processing time for a given packing solution to reduce the computational burden. Training data is generated by solving the motion planning problem for a set of packing solutions using the rapidly exploring random tree algorithm. The Non-Dominated Sorting Genetic Algorithm II searches for the Pareto solutions. Experimental evaluations are conducted using a 6-DOF robot manipulator. The experimental results suggest that implementing the surrogate model can reduce the computational time by 91.1%. The proposed surrogate-assisted optimization method can obtain significantly better solutions than the joint angular velocity-based estimation method. en-copyright= kn-copyright= en-aut-name=LiuZiang en-aut-sei=Liu en-aut-mei=Ziang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawabeTomoya en-aut-sei=Kawabe en-aut-mei=Tomoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishiTatsushi en-aut-sei=Nishi en-aut-mei=Tatsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ItoShun en-aut-sei=Ito en-aut-mei=Shun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujiwaraTomofumi en-aut-sei=Fujiwara en-aut-mei=Tomofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Packing problem kn-keyword=Packing problem en-keyword=sequence-triple kn-keyword=sequence-triple en-keyword=motion planning kn-keyword=motion planning en-keyword=surrogate model kn-keyword=surrogate model en-keyword=multi-objective optimization kn-keyword=multi-objective optimization END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=16 article-no= start-page=2266 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240809 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Long-Term Bonding Performance of One-Bottle vs. Two-Bottle Bonding Agents to Lithium Disilicate Ceramics en-subtitle= kn-subtitle= en-abstract= kn-abstract=The aim of this study was to compare the long-term bonding performance to lithium disilicate (LDS) ceramic between one-bottle and two-bottle bonding agents. Bonding performance was investigated under these LDS pretreatment conditions: with hydrofluoric acid (HF) only, without HF, with a two-bottle bonding agent (Tokuyama Universal Bond II) only. Shear bond strengths between LDS and nine resin cements (both self-adhesive and conventional adhesive types) were measured at three time periods: after one-day water storage (Base), and after 5000 and 20,000 thermocycles (TC 5k and TC 20k respectively). Difference in degradation between one- and two-bottle bonding agents containing the silane coupling agent was compared by high-performance liquid chromatography. With HF pretreatment, bond strengths were not significantly different among the three time periods for each resin cement. Without HF, ESTECEM II and Super-Bond Universal showed significantly higher values than others at TC 5k and TC 20k when treated with the recommended bonding agents, especially at TC 20k. Difference in degradation between one- and two-bottle bonding agents containing the silane coupling agent was compared by high-performance liquid chromatography (HPLC). For both cements, these values at TC 20k were also not significantly different from pretreatment with only Tokuyama Universal Bond II. For LDS, long-term bond durability could be maintained by pretreatment with Tokuyama Universal Bond II instead of the hazardous HF. en-copyright= kn-copyright= en-aut-name=IrieMasao en-aut-sei=Irie en-aut-mei=Masao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkadaMasahiro en-aut-sei=Okada en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MaruoYukinori en-aut-sei=Maruo en-aut-mei=Yukinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishigawaGoro en-aut-sei=Nishigawa en-aut-mei=Goro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MatsumotoTakuya en-aut-sei=Matsumoto en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Biomaterials, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Dental Biomaterials, Tohoku University Graduate School of Dentistry kn-affil= affil-num=3 en-affil=Department of Prosthodontics, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Prosthodontics, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Biomaterials, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=shear bond strength kn-keyword=shear bond strength en-keyword=bonding agent kn-keyword=bonding agent en-keyword=one- vs. two bottles kn-keyword=one- vs. two bottles en-keyword=resin luting materials kn-keyword=resin luting materials en-keyword=lithium disilicate ceramics kn-keyword=lithium disilicate ceramics en-keyword=durability kn-keyword=durability END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=16 article-no= start-page=4108 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240819 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effect of Scaffold Geometrical Structure on Macrophage Polarization during Bone Regeneration Using Honeycomb Tricalcium Phosphate en-subtitle= kn-subtitle= en-abstract= kn-abstract=The polarization balance of M1/M2 macrophages with different functions is important in osteogenesis and bone repair processes. In a previous study, we succeeded in developing honeycomb tricalcium phosphate (TCP), which is a cylindrical scaffold with a honeycomb arrangement of straight pores, and we demonstrated that TCP with 300 and 500 mu m pore diameters (300TCP and 500TCP) induced bone formation within the pores. However, the details of the influence of macrophage polarization on bone formation using engineered biomaterials, especially with respect to the geometric structure of the artificial biomaterials, are unknown. In this study, we examined whether differences in bone tissue formation due to differences in TCP geometry were due to the polarity of the assembling macrophages. Immunohistochemistry for IBA-1, iNOS, and CD163 single staining was performed. The 300TCP showed a marked infiltration of iNOS-positive cells, which are thought to be M1 macrophages, during the osteogenesis process, while no involvement of CD163-positive cells, which are thought to be M2 macrophages, was observed in the TCP pores. In addition, 500TCP showed a clustering of iNOS-positive cells and CD163-positive cells at 2 weeks, suggesting the involvement of M2 macrophages in the formation of bone tissue in the TCP pores. In conclusion, we demonstrated for the first time that the geometrical structure of the artificial biomaterial, i.e., the pore size of honeycomb TCP, affects the polarization of M1/2 macrophages and bone tissue formation in TCP pores. en-copyright= kn-copyright= en-aut-name=TakabatakeKiyofumi en-aut-sei=Takabatake en-aut-mei=Kiyofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsujigiwaHidetsugu en-aut-sei=Tsujigiwa en-aut-mei=Hidetsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakanoKeisuke en-aut-sei=Nakano en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ChangAnqi en-aut-sei=Chang en-aut-mei=Anqi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=PiaoTianyan en-aut-sei=Piao en-aut-mei=Tianyan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=InadaYasunori en-aut-sei=Inada en-aut-mei=Yasunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ArashimaTakuma en-aut-sei=Arashima en-aut-mei=Takuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MorimatsuAyumi en-aut-sei=Morimatsu en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TanakaAyumi en-aut-sei=Tanaka en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KawaiHotaka en-aut-sei=Kawai en-aut-mei=Hotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NagatsukaHitoshi en-aut-sei=Nagatsuka en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Life Science, Faculty of Science, Okayama University of Science kn-affil= affil-num=3 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=11 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=honeycomb TCP kn-keyword=honeycomb TCP en-keyword=bone formation kn-keyword=bone formation en-keyword=macrophages kn-keyword=macrophages en-keyword=polarization kn-keyword=polarization END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=1 article-no= start-page=14543 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240624 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Cervical spinal cord stimulation exerts anti-epileptic effects in a rat model of epileptic seizure through the suppression of CCL2-mediated cascades en-subtitle= kn-subtitle= en-abstract= kn-abstract=Epidural spinal cord stimulation (SCS) is indicated for the treatment of intractable pain and is widely used in clinical practice. In previous basic research, the therapeutic effects of SCS have been demonstrated for epileptic seizure. However, the mechanism has not yet been elucidated. In this study, we investigated the therapeutic effect of SCS and the influence of epileptic seizure. First, SCS in the cervical spine was performed. The rats were divided into four groups: control group and treatment groups with SCS conducted at 2, 50, and 300 Hz frequency. Two days later, convulsions were induced by the intraperitoneal administration of kainic acid, followed by video monitoring to assess seizures. We also evaluated glial cells in the hippocampus by fluorescent immunostaining, electroencephalogram measurements, and inflammatory cytokines such as C-C motif chemokine ligand 2 (CCL2) by quantitative real-time polymerase chain reaction. Seizure frequency and the number of glial cells were significantly lower in the 300 Hz group than in the control group. SCS at 300 Hz decreased gene expression level of CCL2, which induces monocyte migration. SCS has anti-seizure effects by inhibiting CCL2-mediated cascades. The suppression of CCL2 and glial cells may be associated with the suppression of epileptic seizure. en-copyright= kn-copyright= en-aut-name=OkazakiYosuke en-aut-sei=Okazaki en-aut-mei=Yosuke

during an Omicron surge in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Despite the emergence of SARS-CoV-2 variants and waning immunity after initial vaccination, data on antibody kinetics following booster doses, particularly those adapted to Omicron subvariants like XBB.1.5, remain limited. This study assesses the kinetics of anti-spike protein receptor-binding domain (S-RBD) IgG antibody titers post-booster vaccination in a Japanese population during the Omicron variant epidemic.
Methods: A prospective cohort study was conducted in Bizen City, Japan, from November 2023 to January 2024. Participants included residents and workers aged ?18 years, with at least three COVID-19 vaccinations. Antibody levels were measured from venous blood samples. The study analyzed 424 participants and 821 antibody measurements, adjusting for variables such as age, sex, underlying conditions, and prior infection status. Mixed-effects models were employed to describe the kinetics of log-transformed S-RBD antibody titers.
Results: The study found that S-RBD antibody titers declined over time but increased with the number of booster vaccinations, particularly those adapted to Omicron and its subvariant XBB.1.5 (Pfizer-BioNTech Omicron-compatible: 0.156, 95%CI ?0.032 to 0.344; Pfizer-BioNTech XBB-compatible: 0.226; 95%CI ?0.051 to 0.504; Moderna Omicron-compatible: 0.279, 95%CI 0.012 to 0.546; and Moderna XBB-compatible: 0.338, 95%CI ?0.052 to 0.728). Previously infected individuals maintained higher antibody titers, which declined more gradually compared to uninfected individuals (coefficient for interaction with time 0.006; 95%CI 0.001 to 0.011). Sensitivity analyses using Generalized Estimating Equations and interval-censored random intercept model confirmed the robustness of these findings.
Conclusions: The study provides specific data on antibody kinetics post-booster vaccination, including the XBB.1.5-adapted vaccine, in a highly vaccinated Japanese population. The results highlight the importance of considering individual demographics and prior infection history in optimizing vaccination strategies. en-copyright= kn-copyright= en-aut-name=MatsumotoNaomi en-aut-sei=Matsumoto en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SasakiAyako en-aut-sei=Sasaki en-aut-mei=Ayako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KadowakiTomoka en-aut-sei=Kadowaki en-aut-mei=Tomoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakaoSoshi en-aut-sei=Takao en-aut-mei=Soshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=SARS-CoV-2 kn-keyword=SARS-CoV-2 en-keyword=Vaccine kn-keyword=Vaccine en-keyword=Antibody kn-keyword=Antibody en-keyword=Mixed-effects model kn-keyword=Mixed-effects model en-keyword=Omicron kn-keyword=Omicron END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=4 article-no= start-page=313 end-page=322 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202408 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Multicenter Remote-Access Simulation of Vaginal Delivery for High-Flexibility Medical Education during the Coronavirus Pandemic en-subtitle= kn-subtitle= en-abstract= kn-abstract=During the coronavirus pandemic, face-to-face simulation education became impossible. Therefore, we aimed to develop remote-access simulation education with a sense of realism through Information and Communication Technology (ICT) using a perinatal whole-body management and delivery simulator. In September 2021, we administered a multi-center simultaneous remote simulation based on our developed model. Ten universities in the Chugoku?Shikoku region were connected via a web-conferencing system to a live broadcast of a virtual vaginal birth in which a fictional hospitalized pregnant woman experienced accelerated labor and gave birth through vacuum delivery for fetal distress. A Video on Demand (VOD) was made beforehand using a new simulator that allowed for a visual understanding of the process of the inter-vaginal examination. We provided a participatory program that enhanced the sense of realism by combining VOD and real-time lectures on each scenario, with two-way communication between participants and trainee doctors using a chat function. Most participants answered “satisfied” or “very satisfied” with the content, level of difficulty, and level of understanding. From November 2021, we have used the videos of all processes in face-to-face classes. Our construction of a high-flexibility education system using remote simulation in the field of obstetrics and gynecology, especially in the vaginal delivery module, is unique, creative, and sustainable. en-copyright= kn-copyright= en-aut-name=EtoEriko en-aut-sei=Eto en-aut-mei=Eriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MakiJota en-aut-sei=Maki en-aut-mei=Jota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamashitaNoriyuki en-aut-sei=Yamashita en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HasegawaToru en-aut-sei=Hasegawa en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SuemoriAyano en-aut-sei=Suemori en-aut-mei=Ayano kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakatoHikari en-aut-sei=Nakato en-aut-mei=Hikari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ObaHikaru en-aut-sei=Oba en-aut-mei=Hikaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MitomaTomohiro en-aut-sei=Mitoma en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MishimaSakurako en-aut-sei=Mishima en-aut-mei=Sakurako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KirinoSatoe en-aut-sei=Kirino en-aut-mei=Satoe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OhiraAkiko en-aut-sei=Ohira en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=MasuyamaHisashi en-aut-sei=Masuyama en-aut-mei=Hisashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Center for Education in Medicine and Health Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=remote simulator education kn-keyword=remote simulator education en-keyword=perinatal simulator kn-keyword=perinatal simulator en-keyword=information and communication technology kn-keyword=information and communication technology en-keyword=high-flexibility education kn-keyword=high-flexibility education END start-ver=1.4 cd-journal=joma no-vol=378 cd-vols= no-issue= article-no= start-page=113269 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202410 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Mesoporous carbon with extremely low micropore content synthesized from graphene oxide modified with alkali metal nitrates en-subtitle= kn-subtitle= en-abstract= kn-abstract=High-temperature thermal exfoliation is a simple, rapid, and cost-efficient method for transforming graphene oxide (GO) materials into reduced graphene oxide (rGO) materials. In this study, GO materials were dispersed with alkali metal nitrates (MNO3), leading to the preparation of porous rGO materials characterized by high specific surface area (SSA) and pore volume via high-temperature thermal exfoliation. Experimental data indicate that the metal cations of MNO3 tend to react directly with the oxygen functional groups (OFG) of GO, modulating the OFG content. Simultaneously, nitrate anions have preferential interaction with alkali metal ions and adhere to the surface of the GO. The presence of MNO3 on the surface of GO facilitates the thermal exfoliation process and leads to the formation of structures with an extremely high proportion of mesoporous content. The isothermal gas adsorption results show that the exfoliation efficiency of the samples activated with different nitrate salts decreases in the order rGO-KNO3 > rGO-NaNO3 > rGO-LiNO3. Among these samples, rGO modified with KNO3 exhibited the greatest exfoliation efficiency, with a mesopore-to-micropore volume ratio of 22.4, more than 1.7 times that of rGO. Its SSA and pore volume were 359 m2 g?1 and 1.26 cm3 g?1, respectively. These values significantly surpass those of rGO. Our research findings demonstrate that activation with MNO3 significantly increases the SSA and pore volume of the GO material after high-temperature annealing. en-copyright= kn-copyright= en-aut-name=LiZhao en-aut-sei=Li en-aut-mei=Zhao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ToyotaMoeto en-aut-sei=Toyota en-aut-mei=Moeto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OhkuboTakahiro en-aut-sei=Ohkubo en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Department of Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Department of Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=Mesoporous carbon kn-keyword=Mesoporous carbon en-keyword=Alkali metal nitrates kn-keyword=Alkali metal nitrates en-keyword=Oxygen functional groups kn-keyword=Oxygen functional groups en-keyword=Activation kn-keyword=Activation en-keyword=Thermal exfoliation kn-keyword=Thermal exfoliation END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=15 article-no= start-page=4324 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240724 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evolution and Effects of Ad Hoc Multidisciplinary Team Meetings in the Emergency Intensive Care Unit: A Five-Year Analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Multidisciplinary team meetings (MDTMs) are crucial in the ICU. However, daily rounds may not address all sensitive issues due to time constraints and the complexity of cases. This study aimed to describe detailed information and characteristics of ad hoc MDTMs in the ICU. Methods: This single-center, retrospective study analyzed adult emergency ICU admissions at Okayama University Hospital from 1 January 2019 to 31 December 2023. During this period, weekly regular multidisciplinary team ICU rounds were introduced in June 2020, and regular weekday morning MDTMs began in April 2022. A multiple logistic regression analysis was applied to determine the impact of these changes on the frequency of ad hoc MDTMs, adjusting for variables including annual changes. Results: The study analyzed 2487 adult EICU patients, with a median age of 66, and 63.3% of them male. MDTMs were held for 168 patients (6.8%), typically those with severe conditions, including higher COVID-19 prevalence and APACHE II scores, and longer ICU stays. Despite a constant total number of MDTMs, the likelihood of conducting ad hoc MDTMs increased annually (adjusted OR 1.19; 95% CI, 1.04-1.35). Of the 329 MDTMs conducted for these patients, 59.0% addressed end-of-life care, involving an average of 11 participants, mainly nurses and emergency and critical-care physicians. Conclusions: Changes in ICU round and meeting structures might be associated with a higher frequency of conducting ad hoc MDTMs, highlighting their evolving role and importance in patient care management. en-copyright= kn-copyright= en-aut-name=YumotoTetsuya en-aut-sei=Yumoto en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HongoTakashi en-aut-sei=Hongo en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ObaraTakafumi en-aut-sei=Obara en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AgetaKohei en-aut-sei=Ageta en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AokageToshiyuki en-aut-sei=Aokage en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TsukaharaKohei en-aut-sei=Tsukahara en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakaoAtsunori en-aut-sei=Nakao en-aut-mei=Atsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NaitoHiromichi en-aut-sei=Naito en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=clinical conference kn-keyword=clinical conference en-keyword=end-of-life care kn-keyword=end-of-life care en-keyword=ICU rounds kn-keyword=ICU rounds en-keyword=multidisciplinary kn-keyword=multidisciplinary en-keyword=team meetings kn-keyword=team meetings END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=15 article-no= start-page=4384 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240726 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Impact of Serum Indoxyl Sulfate on One-Year Adverse Events in Chronic Kidney Disease Patients with Heart Failure en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: Indoxyl sulfate, a uremic toxin, is associated with mortality and cardiovascular events in patients with chronic kidney disease (CKD). This study aimed to evaluate the prognostic implications of serum indoxyl sulfate levels in patients with heart failure and CKD. Methods and Results: This was a prospective multicenter observational study. Overall, 300 patients with chronic heart failure with a previous history of hospitalization and an estimated glomerular filtration rate (eGFR) of 45 mL/min/1.73 m2 or less (CKD stage G3b to G5) without dialysis were analyzed. The primary outcome assessed in a time-to-event analysis from the measurement of indoxyl sulfate was a composite of all-cause death, hospitalization for heart failure, nonfatal myocardial infarction, and nonfatal stroke. Clinical events were followed-up to one year after indoxyl sulfate measurement. The median patient age was 75 years, and 57% of the patients were men. We divided the cohort into low and high indoxyl sulfate categories according to a median value of 9.63 mg/mL. The primary outcome occurred in 27 of 150 patients (18.0%) in the low indoxyl sulfate group and 27 of 150 patients (18.0%) in the high indoxyl sulfate group (hazard ratio, 1.00; 95% confidence interval, 0.58 to 1.70, p = 0.99). In the post hoc exploratory analyses, the results were consistent across age, sex, body mass index, left ventricular ejection fraction, eGFR, and N-terminal pro b-type natriuretic peptide. Conclusions: Among heart failure patients with CKD stages G3b to 5G, serum indoxyl sulfate concentrations were not significantly associated with the subsequent occurrence of cardiovascular events. en-copyright= kn-copyright= en-aut-name=IwasakiKeiichiro en-aut-sei=Iwasaki en-aut-mei=Keiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyoshiToru en-aut-sei=Miyoshi en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UrabeChikara en-aut-sei=Urabe en-aut-mei=Chikara kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakuragiSatoru en-aut-sei=Sakuragi en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KawaiYusuke en-aut-sei=Kawai en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FukeSoichiro en-aut-sei=Fuke en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=DoiMasayuki en-aut-sei=Doi en-aut-mei=Masayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakaishiAtsushi en-aut-sei=Takaishi en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OkaTakefumi en-aut-sei=Oka en-aut-mei=Takefumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TokunagaNaoto en-aut-sei=Tokunaga en-aut-mei=Naoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=ItoHiroshi en-aut-sei=Ito en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, Okayama University Institute of Academic and Research, Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Okayama University Institute of Academic and Research, Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Cardiovascular Medicine, Okayama University Institute of Academic and Research, Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, Iwakuni Clinical Center kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, Okayama City Hospital kn-affil= affil-num=6 en-affil=Department of Cardiovascular Medicine, Japanese Red Cross Okayama Hospital kn-affil= affil-num=7 en-affil=Department of Cardiology, Kagawa Prefectural Central Hospital kn-affil= affil-num=8 en-affil=Department of Cardiology, Mitoyo General Hospital kn-affil= affil-num=9 en-affil=Department of Cardiology, Tsuyama Chuo Hospital kn-affil= affil-num=10 en-affil=Department of Cardiology, Ibara City Hospital kn-affil= affil-num=11 en-affil=Department of General Internal Medicine 3, Kawasaki Medical School kn-affil= en-keyword=heart failure kn-keyword=heart failure en-keyword=chronic kidney disease kn-keyword=chronic kidney disease en-keyword=indoxyl sulfate kn-keyword=indoxyl sulfate END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=15 article-no= start-page=2930 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240724 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Performance Investigations of VSLAM and Google Street View Integration in Outdoor Location-Based Augmented Reality under Various Lighting Conditions en-subtitle= kn-subtitle= en-abstract= kn-abstract=The growing demand for Location-based Augmented Reality (LAR) experiences has driven the integration of Visual Simultaneous Localization And Mapping (VSLAM) with Google Street View (GSV) to enhance the accuracy. However, the impact of the ambient light intensity on the accuracy and reliability is underexplored, posing significant challenges in outdoor LAR implementations. This paper investigates the impact of light conditions on the accuracy and reliability of the VSLAM/GSV integration approach in outdoor LAR implementations. This study fills a gap in the current literature and offers valuable insights into vision-based approach implementation under different light conditions. Extensive experiments were conducted at five Point of Interest (POI) locations under various light conditions with a total of 100 datasets. Descriptive statistic methods were employed to analyze the data and assess the performance variation. Additionally, the Analysis of Variance (ANOVA) analysis was utilized to assess the impact of different light conditions on the accuracy metric and horizontal tracking time, determining whether there are significant differences in performance across varying levels of light intensity. The experimental results revealed that a significant correlation (p < 0.05) exists between the ambient light intensity and the accuracy of the VSLAM/GSV integration approach. Through the confidence interval estimation, the minimum illuminance 434 lx is needed to provide a feasible and consistent accuracy. Variations in visual references, such as wet surfaces in the rainy season, also impact the horizontal tracking time and accuracy. en-copyright= kn-copyright= en-aut-name=BrataKomang Candra en-aut-sei=Brata en-aut-mei=Komang Candra kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FunabikiNobuo en-aut-sei=Funabiki en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=RiyantokoPrismahardi Aji en-aut-sei=Riyantoko en-aut-mei=Prismahardi Aji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=PandumanYohanes Yohanie Fridelin en-aut-sei=Panduman en-aut-mei=Yohanes Yohanie Fridelin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MentariMustika en-aut-sei=Mentari en-aut-mei=Mustika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=light intensity kn-keyword=light intensity en-keyword=Location-based Augmented Reality (LAR) kn-keyword=Location-based Augmented Reality (LAR) en-keyword=outdoor kn-keyword=outdoor en-keyword=Visual Simultaneous Localization And Mapping (VSLAM) kn-keyword=Visual Simultaneous Localization And Mapping (VSLAM) en-keyword=Google Street View (GSV) kn-keyword=Google Street View (GSV) END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page=341 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240813 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Pathological findings in enucleated eyes of patients with neurofibromatosis type 1: report of a case with 15-year follow-up and review of 14 patients in the literature en-subtitle= kn-subtitle= en-abstract= kn-abstract=Backgrounds Iris nodules are frequently noted as clinical manifestations of neurofibromatosis type 1 but the other intraocular manifestations are rare. The purpose of this study is to present a patient with a phthisic eye who underwent enucleation for a cosmetic reason after 15-year follow-up and also to review 14 patients with enucleation described in the literature.
Case presentation A 17-year-old man with neurofibromatosis type 1 from infancy underwent the enucleation of phthisic left eye and also had the resection of eyelid subcutaneous mass lesions on the left side for a cosmetic reason. He had undergone four-time preceding surgeries for eyelid and orbital mass reduction on the left side in childhood and had developed total retinal detachment 10 years previously. Pathologically, the enucleated eye showed massive retinal gliosis positive for both S-100 and glial fibrillary acidic protein (GFAP) in the area with involvement of the detached retinal neuronal layer, together with a more fibrotic lesion along the choroid which were, in contrast, negative for both S-100 and GFAP. The choroid, ciliary body, and iris did not show apparent neurofibroma while episcleral neurofibroma was present.
Literature review In review of enucleated eyes of 14 patients in the literature, buphthalmic eyes with early-onset glaucoma on the unilateral side was clinically diagnosed in 9 patients who frequently showed varying extent of hemifacial neurofibromatosis which involved the eyelid and orbit on the same side. Pathologically, neurofibromas in varying extent were found in the choroid of 12 patients. One patient showed choroidal malignant melanoma on the left side and fusiform enlargement of the optic nerve on the right side suspected of optic nerve glioma. The phthisic eye in another patient showed massive retinal gliosis similar to the present patient.
Conclusions In summary of the 15 patients with neurofibromatosis type 1, including the present patient, buphthalmic or phthisic eyes with no vision were enucleated for cosmetic reasons and showed choroidal neurofibroma in most patients and massive retinal gliosis in two patients including the present patient. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishidaKenji en-aut-sei=Nishida en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SenoTakaya en-aut-sei=Seno en-aut-mei=Takaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamadaKiyoshi en-aut-sei=Yamada en-aut-mei=Kiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OnoShigeki en-aut-sei=Ono en-aut-mei=Shigeki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Pathology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Plastic and Reconstructive Surgery, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Plastic and Reconstructive Surgery, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Neurological Surgery, General Medical Center, Kawasaki Medical School kn-affil= en-keyword=Neurofibromatosis type 1 kn-keyword=Neurofibromatosis type 1 en-keyword=Enucleation kn-keyword=Enucleation en-keyword=Eye kn-keyword=Eye en-keyword=Pathology kn-keyword=Pathology en-keyword=Massive retinal gliosis kn-keyword=Massive retinal gliosis en-keyword=Choroidal neurofibroma kn-keyword=Choroidal neurofibroma en-keyword=Phthisis kn-keyword=Phthisis en-keyword=Buphthalmos kn-keyword=Buphthalmos en-keyword=Malignant melanoma kn-keyword=Malignant melanoma en-keyword=Cosmetic surgery kn-keyword=Cosmetic surgery END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=14 article-no= start-page=4199 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240718 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=New Delhi Metallo-Beta-Lactamase Inhibitors: A Systematic Scoping Review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: Among various carbapenemases, New Delhi metallo-beta-lactamases (NDMs) are recognized as the most powerful type capable of hydrolyzing all beta-lactam antibiotics, often conferring multi-drug resistance to the microorganism. The objective of this review is to synthesize current scientific data on NDM inhibitors to facilitate the development of future therapeutics for challenging-to-treat pathogens. Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Extension for Scoping Reviews, we conducted a MEDLINE search for articles with relevant keywords from the beginning of 2009 to December 2022. We employed various generic terms to encompass all the literature ever published on potential NDM inhibitors. Results: Out of the 1760 articles identified through the database search, 91 met the eligibility criteria and were included in our analysis. The fractional inhibitory concentration index was assessed using the checkerboard assay for 47 compounds in 37 articles, which included 8 compounds already approved by the Food and Drug Administration (FDA) of the United States. Time-killing curve assays (14 studies, 25%), kinetic assays (15 studies, 40.5%), molecular investigations (25 studies, 67.6%), in vivo studies (14 studies, 37.8%), and toxicity assays (13 studies, 35.1%) were also conducted to strengthen the laboratory-level evidence of the potential inhibitors. None of them appeared to have been applied to human infections. Conclusions: Ongoing research efforts have identified several potential NDM inhibitors; however, there are currently no clinically applicable drugs. To address this, we must foster interdisciplinary and multifaceted collaborations by broadening our own horizons. en-copyright= kn-copyright= en-aut-name=NaharLutfun en-aut-sei=Nahar en-aut-mei=Lutfun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GotohKazuyoshi en-aut-sei=Gotoh en-aut-mei=Kazuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AsaduzzamanMd en-aut-sei=Asaduzzaman en-aut-mei=Md kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Bacteriology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Bacteriology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=antimicrobial resistance kn-keyword=antimicrobial resistance en-keyword=carbapenemase-producing Enterobacterales kn-keyword=carbapenemase-producing Enterobacterales en-keyword=carbapenem-resistant Enterobacterales kn-keyword=carbapenem-resistant Enterobacterales en-keyword=metallo-beta-lactamase kn-keyword=metallo-beta-lactamase en-keyword=synergy kn-keyword=synergy en-keyword=combination kn-keyword=combination END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=13 article-no= start-page=e34206 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240715 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Resolvin D2-induced reparative dentin and pulp stem cells after pulpotomy in a rat model en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Vital pulp therapy (VPT) is performed to preserve dental pulp. However, the biocompatibility of the existing materials is of concern. Therefore, novel materials that can induce pulp healing without adverse effects need to be developed. Resolvin D2 (RvD2), one of specialized pro-resolving mediators, can resolve inflammation and promote the healing of periapical lesions. Therefore, RvD2 may be suitable for use in VPT. In the present study, we evaluated the efficacy of RvD2 against VPT using in vivo and in vitro models.
Methods: First molars of eight-week-old male Sprague?Dawley rats were used for pulpotomy. They were then divided into three treatment groups: RvD2, phosphate-buffered saline, and calcium hydroxide groups. Treatment results were assessed using radiological, histological, and immunohistochemical (GPR18, TNF-α, Ki67, VEGF, TGF-β, CD44, CD90, and TRPA1) analyses. Dental pulp-derived cells were treated with RvD2 in vitro and analyzed using cell-proliferation and cell-migration assays, real-time PCR (Gpr18, Tnf-α, Il-1β, Tgf-β, Vegf, Nanog, and Trpa1), ELISA (VEGF and TGF-β), immunocytochemistry (TRPA1), and flow cytometry (dental pulp stem cells: DPSCs).
Results: The formation of calcified tissue in the pulp was observed in the RvD2 and calcium hydroxide groups. RvD2 inhibited inflammation in dental pulp cells. RvD2 promoted cell proliferation and migration and the expression of TGF-β and VEGF in vitro and in vivo. RvD2 increased the number of DPSCs. In addition, RvD2 suppressed TRPA1 expression as a pain receptor.
Conclusion: RvD2 induced the formation of reparative dentin, anti-inflammatory effects, and decreased pain, along with the proliferation of DPSCs via the expression of VEGF and TGF-β, on the pulp surface in pulpotomy models. en-copyright= kn-copyright= en-aut-name=YonedaMitsuhiro en-aut-sei=Yoneda en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IdeguchiHidetaka en-aut-sei=Ideguchi en-aut-mei=Hidetaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakamuraShin en-aut-sei=Nakamura en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AriasZulema en-aut-sei=Arias en-aut-mei=Zulema kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OnoMitsuaki en-aut-sei=Ono en-aut-mei=Mitsuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OmoriKazuhiro en-aut-sei=Omori en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YamamotoTadashi en-aut-sei=Yamamoto en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakashibaShogo en-aut-sei=Takashiba en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Periodontics and Endodontics, Division of Dentistry, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Pathophysiology-Periodontal Science, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral Science and Translational Research, College of Dental Medicine, Nova Southeastern University kn-affil= affil-num=4 en-affil=Department of Pathophysiology-Periodontal Science, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Molecular Biology and Biochemistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Pathophysiology-Periodontal Science, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=The Center for Graduate Medical Education (Dental Division), Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Pathophysiology-Periodontal Science, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Dental pulp kn-keyword=Dental pulp en-keyword=Regeneration kn-keyword=Regeneration en-keyword=Pulp-capping agents kn-keyword=Pulp-capping agents en-keyword=Specialized pro-resolving mediators kn-keyword=Specialized pro-resolving mediators en-keyword=Resolvin D2 kn-keyword=Resolvin D2 en-keyword=Calcification kn-keyword=Calcification en-keyword=Cytokine kn-keyword=Cytokine en-keyword=TRPA1 kn-keyword=TRPA1 en-keyword=Animal model kn-keyword=Animal model END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=5 article-no= start-page=3322 end-page=3331 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240702 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Prediction of heart failure events based on physiologic sensor data in HINODE defibrillator patients en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aims Hospitalizations are common in patients with heart failure and are associated with high mortality, readmission and economic burden. Detecting early signs of worsening heart failure may enable earlier intervention and reduce hospitalizations. The HeartLogic algorithm is designed to predict worsening heart failure using diagnostic data from multiple device sensors. The main objective of this analysis was to evaluate the sensitivity of the HeartLogic alert calculation in predicting worsening heart failure events (HFEs). We also evaluated the false positive alert rate (FPR) and compared the incidence of HFEs occurring in a HeartLogic alert state to those occurring out of an alert state.
Methods The HINODE study enrolled 144 patients (81 ICD and 63 CRT-D) with device sensor data transmitted via a remote monitoring system. HeartLogic alerts were then retrospectively simulated using relevant sensor data. Clinicians and patients were blinded to calculated alerts. Reported adverse events with HF symptoms were adjudicated and classified by an independent HFE committee. Sensitivity was defined as the ratio of the number of detected usable HFEs (true positives) to the total number of usable HFEs. A false positive alert was defined as an alert with no usable HFE between the alert onset date and the alert recovery date plus 30 days. The patient follow-up period was categorized as in alert state or out of alert state. The event rate ratio was the HFE rate calculated in alert to out of alert.
Results The patient cohort was 79% male and had an average age of 68 +/- 12 years. This analysis yielded 244 years of follow-up data with 73 HFEs from 37 patients. A total of 311 HeartLogic alerts at the nominal threshold (16) occurred across 106 patients providing an alert rate of 1.27 alerts per patient-year. The HFE rate was 8.4 times greater while in alert compared with out of alert (1.09 vs. 0.13 events per patient-year; P < 0.001). At the nominal alert threshold, 80.8% of HFEs were detected by a HeartLogic alert [95% confidence interval (CI): 69.9%-89.1%]. The median time from first true positive alert to an adjudicated clinical HFE was 53 days. The FPR was 1.16 (95% CI: 0.98-1.38) alerts per patient-year.
Conclusions Results suggest that signs of worsening HF can be detected successfully with remote patient follow-up. The use of HeartLogic may predict periods of increased risk for HF or clinically significant events, allowing for early intervention and reduction of hospitalization in a vulnerable patient population. en-copyright= kn-copyright= en-aut-name=NishiiNobuhiro en-aut-sei=Nishii en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakataYasushi en-aut-sei=Sakata en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MuroharaToyoaki en-aut-sei=Murohara en-aut-mei=Toyoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AndoKenji en-aut-sei=Ando en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IkedaTakanori en-aut-sei=Ikeda en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MitsuhashiTakeshi en-aut-sei=Mitsuhashi en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NogamiAkihiko en-aut-sei=Nogami en-aut-mei=Akihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ShimizuWataru en-aut-sei=Shimizu en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SchwartzTorri en-aut-sei=Schwartz en-aut-mei=Torri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KayserTorsten en-aut-sei=Kayser en-aut-mei=Torsten kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=BeaudointCaroline en-aut-sei=Beaudoint en-aut-mei=Caroline kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=AonumaKazutaka en-aut-sei=Aonuma en-aut-mei=Kazutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=for HINODE Investigators en-aut-sei=for HINODE Investigators en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Osaka University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Cardiology, Nagoya University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Department of Cardiology, Kokura Memorial Hospital kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, Toho University Faculty of Medicine kn-affil= affil-num=6 en-affil=Department of Cardiology, Hoshi General Hospital kn-affil= affil-num=7 en-affil=Department of Cardiology, Faculty of Medicine, University of Tsukuba kn-affil= affil-num=8 en-affil=Department of Cardiovascular Medicine, Nippon Medical School kn-affil= affil-num=9 en-affil=Boston Scientific kn-affil= affil-num=10 en-affil=Boston Scientific kn-affil= affil-num=11 en-affil=Boston Scientific kn-affil= affil-num=12 en-affil=Department of Cardiology, Faculty of Medicine, University of Tsukuba kn-affil= affil-num=13 en-affil= kn-affil= en-keyword=HeartLogic kn-keyword=HeartLogic en-keyword=heart failure kn-keyword=heart failure en-keyword=remote monitoring kn-keyword=remote monitoring en-keyword=ICD kn-keyword=ICD en-keyword=CRT kn-keyword=CRT en-keyword=hospitalization kn-keyword=hospitalization END start-ver=1.4 cd-journal=joma no-vol=32 cd-vols= no-issue=11 article-no= start-page=1419 end-page=1432 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202411 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Inverse genetics tracing the differentiation pathway of human chondrocytes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: Mammalian somatic cells can be reprogrammed into induced pluripotent stem cells (iPSCs) via the forced expression of Yamanaka reprogramming factors. However, only a limited population of the cells that pass through a particular pathway can metamorphose into iPSCs, while the others do not. This study aimed to clarify the pathways that chondrocytes follow during the reprogramming process.
Design: The fate of human articular chondrocytes under reprogramming was investigated through a time-coursed single-cell transcriptomic analysis, which we termed an inverse genetic approach. The iPS interference technique was also employed to verify that chondrocytes inversely return to pluripotency following the proper differentiation pathway.
Results: We confirmed that human chondrocytes could be converted into cells with an iPSC phenotype. Moreover, it was clarified that a limited population that underwent the silencing of SOX9, a master gene for chondrogenesis, at a specific point during the proper transcriptome transition pathway, could eventually become iPSCs. Interestingly, the other cells, which failed to be reprogrammed, followed a distinct pathway toward cells with a surface zone chondrocyte phenotype. The critical involvement of cellular communication network factors (CCNs) in this process was indicated. The idea that chondrocytes, when reprogrammed into iPSCs, follow the differentiation pathway backward was supported by the successful iPS interference using SOX9.
Conclusions: This inverse genetic strategy may be useful for seeking candidates for the master genes for the differentiation of various somatic cells. The utility of CCNs in articular cartilage regeneration is also supported. en-copyright= kn-copyright= en-aut-name=DoH.T. en-aut-sei=Do en-aut-mei=H.T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OnoM. en-aut-sei=Ono en-aut-mei=M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WangZ. en-aut-sei=Wang en-aut-mei=Z. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KitagawaW. en-aut-sei=Kitagawa en-aut-mei=W. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=DangA.T. en-aut-sei=Dang en-aut-mei=A.T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YonezawaT. en-aut-sei=Yonezawa en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KubokiT. en-aut-sei=Kuboki en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OohashiT. en-aut-sei=Oohashi en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KubotaS. en-aut-sei=Kubota en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Oral Rehabilitation and Regenerative Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Biochemistry and Molecular Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Cartilage kn-keyword=Cartilage en-keyword=Chondrocyte kn-keyword=Chondrocyte en-keyword=Differentiation kn-keyword=Differentiation en-keyword=Reprogramming kn-keyword=Reprogramming en-keyword=CCN family kn-keyword=CCN family END start-ver=1.4 cd-journal=joma no-vol=49 cd-vols= no-issue=4 article-no= start-page=291 end-page=297 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240330 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluation of the trend of set-up errors during the treatment period using set-up margin in prostate radiotherapy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Accurate information on set-up error during radiotherapy is essential for determining the optimal number of treatments in hypofractionated radiotherapy for prostate cancer. This necessitates careful control by the radiotherapy staff to assess the patient's condition. This study aimed to develop an evaluation method of the temporal trends in a patient's specific prostate movement during treatment using image matching and margin values. This study included 65 patients who underwent prostate volumetric modulated arc therapy (mean treatment time, 87.2 s). Set-up errors were assessed using bone, inter-, and intra-fraction marker matching across 39 fractions. The set-up margin was determined by dividing the four periods into 39 fractions using Stroom's formula and correlation coefficient. The intra-fraction set-up error was biased in the anterior-superior (AS) direction during treatment. The temporal trend of set-up errors during radiotherapy slightly increased based on bone matching and inter-fraction marker matching, with a 1.6-mm difference in the set-up margin fractions 11 to 20. The correlation coefficient of the mean prostate movement during treatment significantly decreased in the superior-inferior direction, while remaining high in the left-right and anterior-posterior directions. Image matching contributed significantly to the improvement of set-up errors; however, careful attention is needed for prostate movement in the AS direction, particularly during short treatment times. Understanding the trend of set-up errors during the treatment period is essential in numerical information sharing on patient condition and evaluating the margins for tailored hypo-fractionated radiotherapy, considering the facility's image-guided radiation therapy technology. en-copyright= kn-copyright= en-aut-name=SasakiHinako en-aut-sei=Sasaki en-aut-mei=Hinako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MorishitaTakumi en-aut-sei=Morishita en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IrieNaho en-aut-sei=Irie en-aut-mei=Naho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KojimaRena en-aut-sei=Kojima en-aut-mei=Rena kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KiriyamaTetsukazu en-aut-sei=Kiriyama en-aut-mei=Tetsukazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakamotoAkira en-aut-sei=Nakamoto en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NishiokaKunio en-aut-sei=Nishioka en-aut-mei=Kunio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakahashiShotaro en-aut-sei=Takahashi en-aut-mei=Shotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TanabeYoshinori en-aut-sei=Tanabe en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University Medical School kn-affil= affil-num=2 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University Medical School kn-affil= affil-num=3 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University Medical School kn-affil= affil-num=4 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University Medical School kn-affil= affil-num=5 en-affil=Department of Radiology, Uwajima City Hospital kn-affil= affil-num=6 en-affil=Department of Radiology, Tokuyama Central Hospital kn-affil= affil-num=7 en-affil=Department of Radiology, Tokuyama Central Hospital kn-affil= affil-num=8 en-affil=Department of Radiology, Tokuyama Central Hospital kn-affil= affil-num=9 en-affil=Department of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= en-keyword=Hypofractionated radiotherapy kn-keyword=Hypofractionated radiotherapy en-keyword=Image-guided radiation therapy kn-keyword=Image-guided radiation therapy en-keyword=Prostate cancer kn-keyword=Prostate cancer en-keyword=Prostate movement kn-keyword=Prostate movement en-keyword=Set-up margin kn-keyword=Set-up margin END start-ver=1.4 cd-journal=joma no-vol=51 cd-vols= no-issue=8 article-no= start-page=1108 end-page=1112 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240619 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The treatment effect of endovascular therapy for chronic limb‐threatening ischemia with systemic sclerosis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Systemic sclerosis (SSc) is a collagen disease with immune abnormalities, vasculopathy, and fibrosis. Ca blockers and prostaglandins are used to treat peripheral circulatory disturbances. Chronic limb-threatening ischemia (CLTI) is a disease characterized by extremity ulcers, necrosis, and pain due to limb ischemia. Since only a few patients present with coexistence of CLTI and SSc, the treatment outcomes of revascularization in these cases are unknown. In this study, we evaluated the clinical characteristics and treatment outcomes of seven patients with CLTI and SSc, and 35 patients with uncomplicated CLTI who were hospitalized from 2012 to 2022. A higher proportion of patients with uncomplicated CLTI had diabetes and male. There were no significant differences in the age at which ischemic ulceration occurred, other comorbidities, or in treatments, including antimicrobial agents, revascularization and amputation, improvement of pain, and the survival time from ulcer onset between the two subgroups. EVT or amputation was performed in six or two of the seven patients with CLTI and SSc, respectively. Among those who underwent EVT, 33% (2/6) achieved epithelialization and 67% (4/6) experienced pain relief. These results suggest that the revascularization in cases with CLTI and SSc should consider factors such as infection and general condition, since revascularization improve the pain of these patients. en-copyright= kn-copyright= en-aut-name=MatsudaYoshihiro en-aut-sei=Matsuda en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyakeTomoko en-aut-sei=Miyake en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TodaHironobu en-aut-sei=Toda en-aut-mei=Hironobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TachibanaKota en-aut-sei=Tachibana en-aut-mei=Kota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NomuraHayato en-aut-sei=Nomura en-aut-mei=Hayato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HiraiYoji en-aut-sei=Hirai en-aut-mei=Yoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KawakamiYoshio en-aut-sei=Kawakami en-aut-mei=Yoshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SakodaNaoya en-aut-sei=Sakoda en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MorizaneShin en-aut-sei=Morizane en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=chronic limb-threatening ischemia (CLTI) kn-keyword=chronic limb-threatening ischemia (CLTI) en-keyword=endovascular therapy (EVT) kn-keyword=endovascular therapy (EVT) en-keyword=revascularization kn-keyword=revascularization en-keyword=systemic sclerosis (SSc) kn-keyword=systemic sclerosis (SSc) END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=11 article-no= start-page=e31872 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240615 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Bacterial DNA and serum IgG antibody titer assays for assessing infection of human-pathogenic and dog-pathogenic Porphyromonas species in dogs en-subtitle= kn-subtitle= en-abstract= kn-abstract=Periodontal disease is highly prevalent in both humans and dogs. Although there have been reports of cross-infection of periodontopathic bacteria, methods for assessing it have yet to be established. The actual status of cross-infection remains to be seen. The purpose of this study was to evaluate the utility of bacterial DNA and serum immunoglobulin G (IgG) antibody titer assays to assess infection of human-pathogenic and dog-pathogenic Porphyromonas species in dogs. Four experimental beagles were used for establishing methods. Sixty-six companion dogs at veterinary clinics visiting for treatment and prophylaxis of periodontal disease were used and divided into healthy, gingivitis, and periodontitis groups. Periodontal pathogens such as Porphyromonas gingivalis and Porphyromonas gulae were investigated as target bacteria. DNA levels of both bacteria were measured using species-specific primers designed for real-time polymerase chain reaction (PCR). Serum IgG titers of both bacteria were measured by enzyme-linked immunosorbent assay (ELISA).
PCR primers were confirmed to have high sensitivity and specificity. However, there was no relationship between the amount of bacterial DNA and the severity of the periodontal disease. In addition, dogs with periodontitis had higher IgG titers against both bacteria compared to dogs in the healthy and gingivitis groups; there was cross-reactivity between the two bacteria. Receiver operating characteristic (ROC) analysis of IgG titers against both bacteria showed high sensitivity (>90 %) and specificity (>75 %). Since both bacteria were distinguished by DNA assays, the combination of these assays may be useful in the evaluation of cross-infection. en-copyright= kn-copyright= en-aut-name=Tai-TokuzenMasako en-aut-sei=Tai-Tokuzen en-aut-mei=Masako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ItoTakashi en-aut-sei=Ito en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TamuraKazuya en-aut-sei=Tamura en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HirayamaHaruko en-aut-sei=Hirayama en-aut-mei=Haruko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OgawaHirohito en-aut-sei=Ogawa en-aut-mei=Hirohito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakamuraShin en-aut-sei=Nakamura en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkuboKeisuke en-aut-sei=Okubo en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OmoriKazuhiro en-aut-sei=Omori en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YamamotoTadashi en-aut-sei=Yamamoto en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MominokiKatsumi en-aut-sei=Mominoki en-aut-mei=Katsumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TakashibaShogo en-aut-sei=Takashiba en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Periodontics and Endodontics, Division of Dentistry, Okayama University Hospital kn-affil= affil-num=2 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Pathophysiology-Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Animal Resources, Advanced Science Research Center, Okayama University kn-affil= affil-num=5 en-affil=Department of Virology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Center for Collaborative Research, Department of Oral Science and Translational Research, Nova Southeastern University kn-affil= affil-num=7 en-affil=Department of Periodontics and Endodontics, Division of Dentistry, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Pathophysiology-Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Comprehensive Dentistry, The Center for Graduate Medical Education (Dental Division), Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Animal Resources, Advanced Science Research Center, Okayama University kn-affil= affil-num=11 en-affil=Department of Pathophysiology-Periodontal Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Cross infection kn-keyword=Cross infection en-keyword=Human and dog kn-keyword=Human and dog en-keyword=Periodontal disease kn-keyword=Periodontal disease en-keyword=Porphyromonas gingivalis kn-keyword=Porphyromonas gingivalis en-keyword=Porphyromonas gulae kn-keyword=Porphyromonas gulae en-keyword=Detection assay kn-keyword=Detection assay END start-ver=1.4 cd-journal=joma no-vol=2024 cd-vols= no-issue= article-no= start-page=6505595 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240528 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Circadian Rhythms Fluctuate the Treatment Effects of Intravesical Treatments on Rat Urinary Frequency Models en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives. It is still not clear how the intravesical instillation of drugs affects rat urinary frequency. This study aimed to examine the dynamics of intravesical treatments' treatment effect on rat urinary frequency models by real-time and extended monitoring using a novel continuous urination monitoring system. Methods. Nine eleven-week-old female Wistar rats were divided into three groups to receive intravesical instillation of 0.1% acetic acid (AA), 1.0% AA, or phosphate-buffered saline (PBS). Thirty minutes later, these drugs were voided, and rats were moved to a continuous urination monitoring system, UM-100. UM-100 monitored rat urination quantitatively and continuously for 24 hours. Rats were then euthanized, and histopathologic examinations using a damage score validated the severity of bladder inflammation. We used nine additional rats to determine the treatment effect of various drugs against the urinary frequency. These rats were also treated with 1.0% AA in the same way and divided into three groups (n = 3 each) to receive intravesical instillation of lidocaine, silver nitrate (AgNO3), or dimethyl sulfoxide (DMSO), respectively. Thirty minutes later, rats were catheterized again and moved to the UM-100, and their voiding was monitored for 24 hours. Results. Intravesical instillation of AA increased the urinary frequency and decreased the mean voided volume (VV) in a concentration-dependent manner, with statistical significance at a concentration of 1.0% (urinary frequency; p = 0.0007 , mean VV; p = 0.0032 , respectively) compared with PBS. Histopathological analysis of these models demonstrated a significantly higher damage score of bladder mucosa in both 0.1% AA and 1.0% AA compared with PBS, with the severity in concordance with the clinical severity of urinary frequency (0.1% AA: p < 0.0001 , 1.0% AA: p < 0.0001 ). Moreover, intravesical instillation of lidocaine, AgNO3, and DMSO decreased the urinary frequency. Continuous monitoring with UM-100 also demonstrated that the treatment effect of these intravesically instilled drugs occurred only at night. Conclusions. The extended monitoring of rat urination by UM-100 revealed a significant fluctuation in the treatment effect of intravesically instilled drugs between day and night. These findings may help establish novel therapies for urinary frequency. en-copyright= kn-copyright= en-aut-name=WatanabeTomofumi en-aut-sei=Watanabe en-aut-mei=Tomofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SadahiraTakuya en-aut-sei=Sadahira en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TominagaYusuke en-aut-sei=Tominaga en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MaruyamaYuki en-aut-sei=Maruyama en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NagasakiNaoya en-aut-sei=Nagasaki en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SekitoTakanori en-aut-sei=Sekito en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=EdamuraKohei en-aut-sei=Edamura en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=WatanabeToyohiko en-aut-sei=Watanabe en-aut-mei=Toyohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ArakiMotoo en-aut-sei=Araki en-aut-mei=Motoo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=WatanabeMasami en-aut-sei=Watanabe en-aut-mei=Masami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=3 article-no= start-page=259 end-page=270 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202406 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Role of the Lipid Profile and Oxidative Stress in Fatigue, Sleep Disorders and Cognitive Impairment in Patients with Multiple Sclerosis en-subtitle= kn-subtitle= en-abstract= kn-abstract=The aim of this study is to investigate the relationship of the lipid profile, dysfunctional high-density lipoprotein, ischaemia-modified albumin and thiol?disulfide homeostasis with cognitive impairment, fatigue and sleep disorders in patients with multiple sclerosis. The cognitive functions of patients were evaluated with the Brief International Cognitive Assessment for Multiple Sclerosis battery. Fatigue was evaluated with the Fatigue Severity Scale and the Fatigue Impact Scale. The Pittsburgh Sleep Quality Index and the Epworth Sleepiness Scale were used to assess patients’ sleep disturbance. Peripheral blood samples were collected, and lipid levels and myeloperoxidase and paraoxonase activity were measured. The myeloperoxidase/paraoxonase ratio, which indicates dysfunctional high-density lipoprotein, was calculated. Thiol?disulfide homeostasis and ischaemia-modified albumin were measured.
We did not identify any relationship between dysfunctional high-density lipoprotein and the physical disability, cognitive decline, fatigue and sleep problems of multiple sclerosis. Thiol?disulfide homeostasis was associated with cognitive scores. The shift of the balance towards disulfide was accompanied by a decrease in cognitive scores. On the other hand, we did not detect any relationship between fatigue and sleep disorders and thiol?disulfide homeostasis. Our findings revealed a possible correlation between cognitive dysfunction and thiol?disulfide homeostasis in multiple sclerosis patients. en-copyright= kn-copyright= en-aut-name=VuralGonul en-aut-sei=Vural en-aut-mei=Gonul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DemirEsra en-aut-sei=Demir en-aut-mei=Esra kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GumusyaylaSadiye en-aut-sei=Gumusyayla en-aut-mei=Sadiye kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ErenFunda en-aut-sei=Eren en-aut-mei=Funda kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=BarakliSerdar en-aut-sei=Barakli en-aut-mei=Serdar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NeseliogluSalim en-aut-sei=Neselioglu en-aut-mei=Salim kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ErelOzcan en-aut-sei=Erel en-aut-mei=Ozcan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Neurology, Faculty of Medicine, Ankara Yildirim Beyazit University kn-affil= affil-num=2 en-affil=Department of Neurology, Ankara City Hospital kn-affil= affil-num=3 en-affil=Department of Neurology, Faculty of Medicine, Ankara Yildirim Beyazit University kn-affil= affil-num=4 en-affil=Department of Clinical Biochemistry, Ankara City Hospital kn-affil= affil-num=5 en-affil=Department of Neurology, Ankara City Hospital kn-affil= affil-num=6 en-affil=Department of Clinical Biochemistry, Ankara City Hospital kn-affil= affil-num=7 en-affil=Department of Clinical Biochemistry, Ankara City Hospital kn-affil= en-keyword=multiple sclerosis kn-keyword=multiple sclerosis en-keyword=dysfunctional HDL kn-keyword=dysfunctional HDL en-keyword=thiol?disulfide homeostasis kn-keyword=thiol?disulfide homeostasis en-keyword=cognitive decline kn-keyword=cognitive decline END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=3 article-no= start-page=237 end-page=243 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202406 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Multidisciplinary Approach to Hip Fractures: Evaluating Outcomes on Mortality and Secondary Hip Fractures en-subtitle= kn-subtitle= en-abstract= kn-abstract=Fracture liaison services (FLS) have been introduced in Japan and several other countries to reduce medical complications and secondary fractures. We aimed to evaluate the effects of the implementation of an FLS approach on patient outcomes during hospitalization at our hospital and over a 2-year follow-up post-injury. This retrospective cohort study included patients ? 60 years admitted to our hospital for hip fragility fractures between October 1, 2016, and July 31, 2020. Patient groups were defined as those treated before (control group, n=238) and after (FLS group, n=196) establishment of the FLS protocol at our institution. The two groups were compared in terms of time to surgery, length of hospital stay, and the incidence of complications after admission, including secondary hip fracture and mortality rates. The follow-up period was 24 months. FLS focuses on early surgery within 48 h of injury and assessing osteoporosis treatment before injury to guide post-discharge anti-osteoporosis medication. FLS reduced the length of hospital stay (p<0.001) and the prevalence of complications after admission (p<0.001), particularly cardiovascular disease, and it increased adherence to anti-osteoporosis medication. These FLS effects resulted in lower secondary hip fracture and mortality rates at 12 and 24 months post-injury. FLS for fragility hip fractures can improve patient outcomes during hospitalization and over a 2-year follow-up period. en-copyright= kn-copyright= en-aut-name=MuraokaOsamu en-aut-sei=Muraoka en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ImaiNorio en-aut-sei=Imai en-aut-mei=Norio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KuraishiTatsuya en-aut-sei=Kuraishi en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ImaiMakoto en-aut-sei=Imai en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FukuharaTakashi en-aut-sei=Fukuhara en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshimineToshifumi en-aut-sei=Yoshimine en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Orthopedic Surgery, Niigata Prefectural Tokamachi Hospital kn-affil= affil-num=2 en-affil=Division of Comprehensive Musculoskeletal Medicine, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=3 en-affil=Department of Orthopedic Surgery, Niigata Prefectural Tokamachi Hospital kn-affil= affil-num=4 en-affil=Department of Orthopedic Surgery, Niigata Prefectural Tokamachi Hospital kn-affil= affil-num=5 en-affil=Department of Orthopedic Surgery, Niigata Prefectural Tokamachi Hospital kn-affil= affil-num=6 en-affil=Department of Internal Medicine, Niigata Prefectural Tokamachi Hospital kn-affil= en-keyword=fracture liaison services kn-keyword=fracture liaison services en-keyword=complications after admission kn-keyword=complications after admission en-keyword=secondary hip fracture kn-keyword=secondary hip fracture en-keyword=mortality kn-keyword=mortality END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=3 article-no= start-page=227 end-page=235 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202406 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effect of Lipopolysaccharide on the Duration of Zolpidem-Induced Loss of Righting Reflex in Mice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Zolpidem, a non-benzodiazepine hypnotic, is primarily used to treat insomnia. In a previous study, pior treatment with non-benzodiazepine receptor agonists was associated with inflammation. The present study aimed to clarify the association between the effects of zolpidem and inflammation in mice treated with lipopolysaccharide (LPS), a known model of inflammation. We assessed the zolpidem-induced loss of righting reflex (LORR) duration 24 h after LPS treatment in mice. Additionally, the expressions of γ-aminobutyric acid (GABA)A receptor subunit and K+-Cl? cotransporter isoform 2 (KCC2) mRNA in the hippocampus and frontal cortex were examined in LPS-treated mice. Pretreatment with LPS was associated with significantly prolonged duration of zolpidem-induced LORR compared to control mice. This effect was significantly attenuated by administering bicuculline, a GABAA receptor antagonist, or flumazenil, a benzodiazepine receptor antagonist, in LPS-treated mice. Compared to controls, LPS-treated mice showed no significant change in the expression of GABAA receptor subunits in the hippocampus or frontal cortex. Bumetanide, an Na+-K+-2Cl? cotransporter isoform 1 blocker, attenuated the extended duration of zolpidem-induced LORR observed in LPS-treated mice. LPS significantly decreased Kcc2 mRNA expression in the hippocampus and the frontal cortex. These findings suggest that inflammation increases zolpidem-induced LORR, possibly through a reduction in KCC2 expression. en-copyright= kn-copyright= en-aut-name=WadaYudai en-aut-sei=Wada en-aut-mei=Yudai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UshioSoichiro en-aut-sei=Ushio en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KitamuraYoshihisa en-aut-sei=Kitamura en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ZamamiYoshito en-aut-sei=Zamami en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SendoToshiaki en-aut-sei=Sendo en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Clinical Pharmacy, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Clinical Pharmacy, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Clinical Pharmacy, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Clinical Pharmacy, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=lipopolysaccharide kn-keyword=lipopolysaccharide en-keyword=zolpidem kn-keyword=zolpidem en-keyword=GABAA receptor kn-keyword=GABAA receptor en-keyword=K+-Cl? cotransporters kn-keyword=K+-Cl? cotransporters END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=5 article-no= start-page=e0302537 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240521 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The use of artificial intelligence in induced pluripotent stem cell-based technology over 10-year period: A systematic scoping review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background

Currently, research on response inhibition remains controversial, and the neurobiological mechanisms associated with response inhibition are still being explored. The Go/No-Go task is a widely used paradigm that can be used to effectively assess response inhibition capability. While many studies have utilized equal numbers of Go and No-Go trials, how different ratios affect response inhibition remains unknown; (2) Methods: This study investigated the impact of different ratios of Go and No-Go conditions on response inhibition using the Go/No-Go task combined with event-related potential (ERP) techniques; (3) Results: The results showed that as the proportion of Go trials decreased, behavioral performance in Go trials significantly improved in terms of response time, while error rates in No-Go trials gradually decreased. Additionally, the NoGo-P3 component at the central average electrodes (Cz, C1, C2, FCz, FC1, FC2, PCz, PC1, and PC2) exhibited reduced amplitude and latency; (4) Conclusions: These findings indicate that different ratios in Go/No-Go tasks influence response inhibition, with the brain adjusting processing capabilities and rates for response inhibition. This effect may be related to the brain's predictive mechanism model. en-copyright= kn-copyright= en-aut-name=ZhangNan en-aut-sei=Zhang en-aut-mei=Nan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AnWeichao en-aut-sei=An en-aut-mei=Weichao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YuYinghua en-aut-sei=Yu en-aut-mei=Yinghua kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WuJinglong en-aut-sei=Wu en-aut-mei=Jinglong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YangJiajia en-aut-sei=Yang en-aut-mei=Jiajia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Graduate of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Graduate of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=Graduate of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=5 en-affil=Graduate of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=response inhibition kn-keyword=response inhibition en-keyword=ratio kn-keyword=ratio en-keyword=go/no-go task kn-keyword=go/no-go task en-keyword=ERP kn-keyword=ERP en-keyword=NoGo-P3 component kn-keyword=NoGo-P3 component END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=10 article-no= start-page=807 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240509 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Exploring the Regulators of Keratinization: Role of BMP-2 in Oral Mucosa en-subtitle= kn-subtitle= en-abstract= kn-abstract=The oral mucosa functions as a physico-chemical and immune barrier to external stimuli, and an adequate width of the keratinized mucosa around the teeth or implants is crucial to maintaining them in a healthy and stable condition. In this study, for the first time, bulk RNA-seq analysis was performed to explore the gene expression of laser microdissected epithelium and lamina propria from mice, aiming to investigate the differences between keratinized and non-keratinized oral mucosa. Based on the differentially expressed genes (DEGs) and Gene Ontology (GO) Enrichment Analysis, bone morphogenetic protein 2 (BMP-2) was identified to be a potential regulator of oral mucosal keratinization. Monoculture and epithelial-mesenchymal cell co-culture models in the air-liquid interface (ALI) indicated that BMP-2 has direct and positive effects on epithelial keratinization and proliferation. We further performed bulk RNA-seq of the ALI monoculture stimulated with BMP-2 in an attempt to identify the downstream factors promoting epithelial keratinization and proliferation. Analysis of the DEGs identified, among others, IGF2, ID1, LTBP1, LOX, SERPINE1, IL24, and MMP1 as key factors. In summary, these results revealed the involvement of a well-known growth factor responsible for bone development, BMP-2, in the mechanism of oral mucosal keratinization and proliferation, and pointed out the possible downstream genes involved in this mechanism. en-copyright= kn-copyright= en-aut-name=MuXindi en-aut-sei=Mu en-aut-mei=Xindi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OnoMitsuaki en-aut-sei=Ono en-aut-mei=Mitsuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NguyenHa Thi Thu en-aut-sei=Nguyen en-aut-mei=Ha Thi Thu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WangZiyi en-aut-sei=Wang en-aut-mei=Ziyi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ZhaoKun en-aut-sei=Zhao en-aut-mei=Kun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KomoriTaishi en-aut-sei=Komori en-aut-mei=Taishi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YonezawaTomoko en-aut-sei=Yonezawa en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KubokiTakuo en-aut-sei=Kuboki en-aut-mei=Takuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OohashiToshitaka en-aut-sei=Oohashi en-aut-mei=Toshitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil= kn-affil=Department of Oral Rehabilitation and Regenerative Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=7 en-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Oral Rehabilitation and Implantology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=cell differentiation kn-keyword=cell differentiation en-keyword=epithelia kn-keyword=epithelia en-keyword=growth factor(s) kn-keyword=growth factor(s) en-keyword=bioinformatics kn-keyword=bioinformatics en-keyword=extracellular matrix (ECM) kn-keyword=extracellular matrix (ECM) en-keyword=mucocutaneous disorders kn-keyword=mucocutaneous disorders END start-ver=1.4 cd-journal=joma no-vol=452 cd-vols= no-issue= article-no= start-page=115613 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240701 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Photochemical synthesis and solvatochromic fluorescence behavior of imide-fused phenacenes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Chrysenes, picene, fulminene, modified with imide, bromo, and amino functionalities, were synthesized through Mallory photoreaction as the key step, and their electronic spectra were investigated. Fluorescence spectra of chrysene-diimide CHRDI and bromo-substituted phencanene-imides, BrCHRI, BrPICI, BrFULI were dependent on solvent polarity to display appreciable fluorescence color changes. The solvatofluorochromic behavior was analyzed by conventional relationships between Stokes shift and solvent polarity parameters, such as Lippert-Mataga and Bilot-Kawski equations. The results indicated that the solvatofluorochromism was derived from the intramolecular charge transfer (ICT) nature in the excited state. Theoretical studies using time-dependent density-functional theory revealed that the phenacene-imide molecules in the fluorescent state possessed ICT characters between the strongly electron-withdrawing imide moiety and moderately electron-donating phenacene cores. Amino-substituted chrysene-imide NH2CHRI showed fluorescence band in a red region (λFL = 618 nm) in toluene with a very large Stokes shift (Δ nu= 7630 cm?1) suggesting that the molecule in the fluorescent state was highly polarized. The present results indicate that phenacenes would provide potential platforms for constructing future functional fluorophores through an appropriate functionalization. en-copyright= kn-copyright= en-aut-name=NoseKeito en-aut-sei=Nose en-aut-mei=Keito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamajiMinoru en-aut-sei=Yamaji en-aut-mei=Minoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TaniFumito en-aut-sei=Tani en-aut-mei=Fumito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=GotoKenta en-aut-sei=Goto en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkamotoHideki en-aut-sei=Okamoto en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Division of Molecular Science, Graduate School of Science and Engineering, Gunma University kn-affil= affil-num=3 en-affil=Institute for Materials Chemistry and Engineering, Kyushu University kn-affil= affil-num=4 en-affil=Institute for Materials Chemistry and Engineering, Kyushu University kn-affil= affil-num=5 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Phenacene kn-keyword=Phenacene en-keyword=Imide kn-keyword=Imide en-keyword=Fluorescence kn-keyword=Fluorescence en-keyword=Solvatofluorochromism kn-keyword=Solvatofluorochromism en-keyword=Intramolecular charge transfer kn-keyword=Intramolecular charge transfer END start-ver=1.4 cd-journal=joma no-vol=28 cd-vols= no-issue=1 article-no= start-page=160 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240513 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Organ donation after extracorporeal cardiopulmonary resuscitation: a nationwide retrospective cohort study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Limited data are available on organ donation practices and recipient outcomes, particularly when comparing donors who experienced cardiac arrest and received extracorporeal cardiopulmonary resuscitation (ECPR) followed by veno-arterial extracorporeal membrane oxygenation (ECMO) decannulation, versus those who experienced cardiac arrest without receiving ECPR. This study aims to explore organ donation practices and outcomes post-ECPR to enhance our understanding of the donation potential after cardiac arrest.
Methods We conducted a nationwide retrospective cohort study using data from the Japan Organ Transplant Network database, covering all deceased organ donors between July 17, 2010, and August 31, 2022. We included donors who experienced at least one episode of cardiac arrest. During the study period, patients undergoing ECMO treatment were not eligible for a legal diagnosis of brain death. We compared the timeframes associated with each donor's management and the long-term graft outcomes of recipients between ECPR and non-ECPR groups.
Results Among 370 brain death donors with an episode of cardiac arrest, 26 (7.0%) received ECPR and 344 (93.0%) did not; the majority were due to out-of-hospital cardiac arrests. The median duration of veno-arterial ECMO support after ECPR was 3 days. Patients in the ECPR group had significantly longer intervals from admission to organ procurement compared to those not receiving ECPR (13 vs. 9 days, P = 0.005). Lung graft survival rates were significantly lower in the ECPR group (log-rank test P = 0.009), with no significant differences in other organ graft survival rates. Of 160 circulatory death donors with an episode of cardiac arrest, 27 (16.9%) received ECPR and 133 (83.1%) did not. Time intervals from admission to organ procurement following circulatory death and graft survival showed no significant differences between ECPR and non-ECPR groups. The number of organs donated was similar between the ECPR and non-ECPR groups, regardless of brain or circulatory death.
Conclusions This nationwide study reveals that lung graft survival was lower in recipients from ECPR-treated donors, highlighting the need for targeted research and protocol adjustments in post-ECPR organ donation. en-copyright= kn-copyright= en-aut-name=YumotoTetsuya en-aut-sei=Yumoto en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsukaharaKohei en-aut-sei=Tsukahara en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ObaraTakafumi en-aut-sei=Obara en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HongoTakashi en-aut-sei=Hongo en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NojimaTsuyoshi en-aut-sei=Nojima en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NaitoHiromichi en-aut-sei=Naito en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakaoAtsunori en-aut-sei=Nakao en-aut-mei=Atsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Brain death kn-keyword=Brain death en-keyword=Cardiopulmonary resuscitation kn-keyword=Cardiopulmonary resuscitation en-keyword=Extracorporeal membrane oxygenation kn-keyword=Extracorporeal membrane oxygenation en-keyword=Organ transplantation kn-keyword=Organ transplantation en-keyword=Out-of-hospital cardiac arrest kn-keyword=Out-of-hospital cardiac arrest en-keyword=Tissue and organ procurement kn-keyword=Tissue and organ procurement END start-ver=1.4 cd-journal=joma no-vol=1828 cd-vols= no-issue= article-no= start-page=148790 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Protective effect of scallop-derived plasmalogen against vascular dysfunction, via the pSTAT3/PIM1/NFATc1 axis, in a novel mouse model of Alzheimer’s disease with cerebral hypoperfusion en-subtitle= kn-subtitle= en-abstract= kn-abstract=A strong relationship between Alzheimer’s disease (AD) and vascular dysfunction has been the focus of increasing attention in aging societies. In the present study, we examined the long-term effect of scallop-derived plasmalogen (sPlas) on vascular remodeling-related proteins in the brain of an AD with cerebral hypoperfusion (HP) mouse model. We demonstrated, for the first time, that cerebral HP activated the axis of the receptor for advanced glycation endproducts (RAGE)/phosphorylated signal transducer and activator of transcription 3 (pSTAT3)/provirus integration site for Moloney murine leukemia virus 1 (PIM1)/nuclear factor of activated T cells 1 (NFATc1), accounting for such cerebral vascular remodeling. Moreover, we also found that cerebral HP accelerated pSTAT3-mediated astrogliosis and activation of the nucleotide-binding domain and leucine-rich repeat protein 3 (NLRP3) inflammasome, probably leading to cognitive decline. On the other hand, sPlas treatment attenuated the activation of the pSTAT3/PIM1/NFATc1 axis independent of RAGE and significantly suppressed NLRP3 inflammasome activation, demonstrating the beneficial effect on AD. en-copyright= kn-copyright= en-aut-name=ZhaiYun en-aut-sei=Zhai en-aut-mei=Yun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MoriharaRyuta en-aut-sei=Morihara

kn-subject= en-title= kn-title=Swelling Stress of Bentonite: Thermodynamics of Interlayer Water in K-Montmorillonite in Consideration of Alteration en-subtitle= kn-subtitle= en-abstract= kn-abstract=The buffer material that makes up the geological disposal system of high-level waste swells by contact with groundwater and seals space with rock mass and fractures in rock mass. The buffer material has a function of mechanical buffer with rock pressure, and swelling stress is important in this case. The alteration of bentonite may occur due to the initial replacement of cations (Na+ ions) in the interlayer with K+ ions upon contact with groundwater, but there are no studies on the swelling stress of K-bentonite. In this study, the author prepared K-montmorillonite samples and obtained thermodynamic data on interlayer water as a function of water content using a relative humidity method. The swelling stress was analyzed based on a thermodynamic model developed in earlier studies and compared with measured data. The activity and the relative partial molar Gibbs free energy of porewater decreased with decreasing water content in the region, below approximately 15%. This behavior significantly differs from that of other ions, such as Na. The swelling stress calculated based on the thermodynamic model and date occurred in the region of high density of 1.9 Mg/m3 with montmorillonite partial density. It was indicated for the first time that K-bentonite scarcely swells under realistic design conditions. en-copyright= kn-copyright= en-aut-name=EndoMisato en-aut-sei=Endo en-aut-mei=Misato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SatoHaruo en-aut-sei=Sato en-aut-mei=Haruo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Institute of Academic and Research, Okayama University kn-affil= en-keyword=swelling stress kn-keyword=swelling stress en-keyword=K-montmorillonite kn-keyword=K-montmorillonite en-keyword=thermodynamic data kn-keyword=thermodynamic data en-keyword=interlayer water kn-keyword=interlayer water en-keyword=relative humidity method kn-keyword=relative humidity method END start-ver=1.4 cd-journal=joma no-vol=54 cd-vols= no-issue=11 article-no= start-page=1319 end-page=1328 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240418 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effective division of the intersegmental plane using a robotic stapler in robotic pulmonary segmentectomy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purposes Robot-assisted thoracoscopic (RATS) segmentectomy is becoming increasingly common because of the expanded indications for segmentectomy and the widespread adoption of robotic surgery. The precise division of the intersegmental plane is necessary to ensure oncologic margins from the tumor and to preserve the lung function. In this study, we present a strategy for accurately dividing the intersegmental plane using a robotic stapler and review the surgical outcomes.
Methods RATS portal segmentectomy was performed using the Da Vinci Xi system and the intersegmental plane was dissected using a robotic stapler. We evaluated the perioperative outcomes in 92 patients who underwent RATS portal segmentectomy between May 2020 and January 2023. These results were compared with those of 82 patients who underwent complete video-assisted thoracoscopic surgery (CVATS) during the same period.
Results The operative and console times were 162 and 97 min, respectively. No intraoperative complications occurred, and postoperative complications were observed in four cases (4.3%). The operative time, blood loss, postoperative complications, and maximum incision size were significantly lower in the RATS group than in the CVATS group. However, RATS requires a significantly higher number of staplers than CVATS.
Conclusions The division of the intersegmental plane using a robotic stapler in RATS portal segmentectomy was, therefore, found to be safe and effective. en-copyright= kn-copyright= en-aut-name=OkazakiMikio en-aut-sei=Okazaki en-aut-mei=Mikio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SuzawaKen en-aut-sei=Suzawa en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShienKazuhiko en-aut-sei=Shien en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HashimotoKohei en-aut-sei=Hashimoto en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanakaShin en-aut-sei=Tanaka en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyoshiKentaroh en-aut-sei=Miyoshi en-aut-mei=Kentaroh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YamamotoHiromasa en-aut-sei=Yamamoto en-aut-mei=Hiromasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SugimotoSeiichiro en-aut-sei=Sugimoto en-aut-mei=Seiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Pulmonary segmentectomy kn-keyword=Pulmonary segmentectomy en-keyword=Robot-assisted thoracic surgery kn-keyword=Robot-assisted thoracic surgery en-keyword=Robotic segmentectomy kn-keyword=Robotic segmentectomy en-keyword=Robotic stapler kn-keyword=Robotic stapler END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=4 article-no= start-page=394 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240410 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Changes of Temperature and Moisture Distribution over Time by Thermo-Hydro-Chemical (T-H-C)-Coupled Analysis in Buffer Material Focusing on Montmorillonite Content en-subtitle= kn-subtitle= en-abstract= kn-abstract=Bentonite is used as a buffer material in engineered barriers for the geological disposal of high-level radioactive waste. The buffer material will be made of bentonite, a natural clay, mixed with silica sand. The buffer material is affected by decay heat from high-level radioactive waste, infiltration of groundwater, and swelling of the buffer material. The analysis of these factors requires coupled analysis of heat transfer, moisture transfer, and groundwater chemistry. The purpose of this study is to develop a model to evaluate bentonite types and silica sand content in a unified manner for thermo-hydro-chemical (T-H-C)-coupled analysis in buffer materials. We focused on the content of the clay mineral montmorillonite, which is the main component of bentonite, and developed a model to derive the moisture diffusion coefficient of liquid water and water vapor based on Philip and de Vries, and Kozeny-Carman. The evolutions of the temperature and moisture distribution in the buffer material were analyzed, and the validity of each distribution was confirmed by comparison with the measured data obtained from an in situ experiment at 350 m in depth at the Horonobe Underground Research Center, Hokkaido, Japan. en-copyright= kn-copyright= en-aut-name=OuchiKohei en-aut-sei=Ouchi en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SatoHaruo en-aut-sei=Sato en-aut-mei=Haruo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=geological disposal kn-keyword=geological disposal en-keyword=buffer material kn-keyword=buffer material en-keyword=T-H-C-coupled analysis kn-keyword=T-H-C-coupled analysis en-keyword=montmorillonite kn-keyword=montmorillonite en-keyword=bentonite kn-keyword=bentonite END start-ver=1.4 cd-journal=joma no-vol=408 cd-vols= no-issue=1 article-no= start-page=284 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230720 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Innovative suture technique for robotic hepaticojejunostomy: double-layer interrupted sutures en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose Biliary reconstruction remains a technically demanding and complicated procedure in minimally invasive hepatopancreatobiliary surgeries. No optimal hepaticojejunostomy (HJ) technique has been demonstrated to be superior for preventing biliary complications. This study aimed to investigate the feasibility of our unique technique of posterior double-layer interrupted sutures in robotic HJ.
Methods We performed a retrospective analysis of a prospectively collected database. Forty-two patients who underwent robotic pancreatoduodenectomy using this technique between September 2020 and November 2022 at our center were reviewed. In the posterior double-layer interrupted technique, sutures were placed to bite the bile duct, posterior seromuscular layer of the jejunum, and full thickness of the jejunum.
Results The median operative time was 410 (interquartile range [IQR], 388?478) min, and the median HJ time was 30 (IQR, 28?39) min. The median bile duct diameter was 7 (IQR, 6?10) mm. Of the 42 patients, one patient (2.4%) had grade B bile leakage. During the median follow-up of 12.6 months, one patient (2.4%) with bile leakage developed anastomotic stenosis. Perioperative mortality was not observed. A surgical video showing the posterior double-layer interrupted sutures in the robotic HJ is included.
Conclusions Posterior double-layer interrupted sutures in robotic HJ provided a simple and feasible method for biliary reconstruction with a low risk of biliary complications. en-copyright= kn-copyright= en-aut-name=TakagiKosei en-aut-sei=Takagi en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UmedaYuzo en-aut-sei=Umeda en-aut-mei=Yuzo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YoshidaRyuichi en-aut-sei=Yoshida en-aut-mei=Ryuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujiTomokazu en-aut-sei=Fuji en-aut-mei=Tomokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YasuiKazuya en-aut-sei=Yasui en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YagiTakahito en-aut-sei=Yagi en-aut-mei=Takahito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Hepaticojejunostomy kn-keyword=Hepaticojejunostomy en-keyword=Robotic surgery kn-keyword=Robotic surgery en-keyword=Pancreatoduodenectomy kn-keyword=Pancreatoduodenectomy en-keyword=Biliary complications kn-keyword=Biliary complications END start-ver=1.4 cd-journal=joma no-vol=28 cd-vols= no-issue=7 article-no= start-page=847 end-page=859 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230509 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Trends and issues in clinical research on satisfaction and quality of life after mastectomy and breast reconstruction: a 5-year scoping review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Breast reconstruction (BR) aims to improve the satisfaction and quality of life (QOL) of breast cancer survivors. Clinical studies using patient-reported outcomes (PROs) can therefore provide relevant information to the patients and support decision-making. This scoping review was conducted to analyze recent trends in world regions, methods used, and factors investigated. The literature search was conducted in August 2022. Databases of PubMed, MEDLINE, and CINAHL were searched for relevant English-language studies published from 2017 to 2022. Studies involving women with breast cancer who underwent BR after mastectomy and investigated PROs after BR using BR-specific scales were included. Data on the country, publication year, study design, PRO measures (PROMs) used, time points of surveys, and research themes were collected. In total, 147 articles met the inclusion criteria. BREAST-Q was the most widely used, contributing to the increase in the number and diversification of studies in this area. Such research has been conducted mainly in North America and Europe and is still developing in Asia and other regions. The research themes involved a wide range of clinical and patient factors in addition to surgery, which could be influenced by research methods, time since surgery, and even cultural differences. Recent BR-specific PROMs have led to a worldwide development of research on factors that affect satisfaction and QOL after BR. PRO after BR may be influenced by local cultural and social features, and it would be necessary to accumulate data in each region to draw clinically useful conclusion. en-copyright= kn-copyright= en-aut-name=SaigaMiho en-aut-sei=Saiga en-aut-mei=Miho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakagiriRyoko en-aut-sei=Nakagiri en-aut-mei=Ryoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MukaiYuko en-aut-sei=Mukai en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsumotoHiroshi en-aut-sei=Matsumoto en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KimataYoshihiro en-aut-sei=Kimata en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Plastic Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Plastic Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Plastic Surgery, Okayama Rosai Hospital kn-affil= affil-num=4 en-affil=Department of Plastic and Reconstructive Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Plastic and Reconstructive Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Patient-reported outcomes kn-keyword=Patient-reported outcomes en-keyword=Breast reconstruction kn-keyword=Breast reconstruction en-keyword=Breast cancer kn-keyword=Breast cancer en-keyword=Quality of life kn-keyword=Quality of life en-keyword=Satisfaction kn-keyword=Satisfaction END start-ver=1.4 cd-journal=joma no-vol=63 cd-vols= no-issue=3 article-no= start-page=ezad048 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230208 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Surgical outcome of ipsilateral anatomical resection for lung cancer after pulmonary lobectomy en-subtitle= kn-subtitle= en-abstract= kn-abstract=OBJECTIVES: Ipsilateral reoperation after pulmonary lobectomy is often challenging because of adhesions from the previous operation. We retrospectively examined the surgical outcome and prognosis of ipsilateral anatomical resection for lung cancer after pulmonary lobectomy using a multicentre database.
METHODS: We evaluated the perioperative outcomes and overall survival of 51 patients who underwent pulmonary lobectomy followed by ipsilateral anatomical resection for lung cancer between January 2012 and December 2018. In addition, patients with stage I non-small-cell lung cancer (NSCLC) were compared with 3411 patients with stage I lung cancer who underwent pulmonary resection without a prior ipsilateral lobectomy.
RESULTS: Ipsilateral anatomical resections included 10 completion pneumonectomies, 19 pulmonary lobectomies and 22 pulmonary segmentectomies. Operative time was 312.2?±?134.5?min, and intraoperative bleeding was 522.2?±?797.5?ml. Intraoperative and postoperative complications occurred in 9 and 15 patients, respectively. However, the 5-year overall survival rate after anatomical resection followed by ipsilateral lobectomy was 83.5%. Furthermore, in patients with c-stage I NSCLC, anatomical resection followed by ipsilateral lobectomy was not associated with worse survival than anatomical resection without prior ipsilateral lobectomy.
CONCLUSIONS: Anatomical resection following ipsilateral lobectomy is associated with a high frequency of intraoperative and postoperative complications. However, the 5-year overall survival in patients with c-stage I NSCLC who underwent ipsilateral anatomical resection after pulmonary lobectomy is comparable to that in patients who underwent anatomical resection without prior pulmonary lobectomy. en-copyright= kn-copyright= en-aut-name=OkazakiMikio en-aut-sei=Okazaki en-aut-mei=Mikio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1

kn-title=Endoscopic manifestation of intestinal transplant-associated microangiopathy after stem cell transplantation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Endoscopic features of intestinal transplant-associated microangiopathy (iTAM) have not been comprehensively investigated. This study aimed to examine the endoscopic characteristics of patients diagnosed with iTAM.
Methods This retrospective analysis included 14 patients pathologically diagnosed with iTAM after stem cell transplantation for hematolymphoid neoplasms (n = 13) or thalassemia (n = 1). The sex, age at diagnosis, endoscopic features, and prognosis of each patient were assessed. Serological markers for diagnosing transplant-associated thrombotic microangiopathy were also evaluated.
Results The mean age at the time of iTAM diagnosis was 40.2 years. Patients diagnosed based on the pathognomonic pathological changes of iTAM presented with diverse symptoms at the times of endoscopic examinations, including diarrhea (n = 10), abdominal pain (n = 5), nausea (n = 4), appetite loss (n = 2), bloody stools (n = 2), abdominal discomfort (n = 1), and vomiting (n = 1). At the final follow-up, six patients survived, while eight patients succumbed, with a median time of 100.5 days (range: 52-247) post-diagnosis. Endoscopic manifestations included erythematous mucosa (n = 14), erosions (n = 13), ulcers (n = 9), mucosal edema (n = 9), granular mucosa (n = 9), and villous atrophy (n = 4). Erosions and/or ulcers were primarily observed in the colon (10/14, 71%), followed by the ileum (9/13, 69%), stomach (4/10, 40%), cecum (5/14, 36%), duodenum (3/10, 30%), rectum (4/14, 29%), and esophagus (1/10, 10%). Cytomegalovirus infection (n = 4) and graft-versus-host disease (n = 2) coexisted within the gastrointestinal tract. Patients had de novo prolonged or progressive thrombocytopenia (6/14, 43%), decreased hemoglobin concentration (4/14, 29%), reduced serum haptoglobin level (3/14, 21%), and a sudden and persistent increase in lactate dehydrogenase level (2/14, 14%). Peripheral blood samples from 12 patients were evaluated for schistocytes, with none exceeding 4%.
Conclusions This study provides a comprehensive exploration of the endoscopic characteristics of iTAM. Notably, all patients exhibited erythematous mucosa throughout the gastrointestinal tract, accompanied by prevalent manifestations, such as erosions (93%), ulcers (64%), mucosal edema (64%), granular mucosa (64%), and villous atrophy (29%). Because of the low positivity for serological markers of transplant-associated thrombotic microangiopathy in patients with iTAM, endoscopic evaluation and biopsy of these lesions are crucial, even in the absence of these serological features. en-copyright= kn-copyright= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=EnnishiDaisuke en-aut-sei=Ennishi en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiiNobuharu en-aut-sei=Fujii en-aut-mei=Nobuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsuokaKen-Ichi en-aut-sei=Matsuoka en-aut-mei=Ken-Ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=InokuchiToshihiro en-aut-sei=Inokuchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HiraokaSakiko en-aut-sei=Hiraoka en-aut-mei=Sakiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Colonoscopy kn-keyword=Colonoscopy en-keyword=Esophagogastroduodenoscopy kn-keyword=Esophagogastroduodenoscopy en-keyword=Graft-versus-host disease kn-keyword=Graft-versus-host disease en-keyword=Hematopoietic stem cell transplantation kn-keyword=Hematopoietic stem cell transplantation en-keyword=Intestinal transplant-associated microangiopathy kn-keyword=Intestinal transplant-associated microangiopathy en-keyword=iTAM kn-keyword=iTAM END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=2 article-no= start-page=163 end-page=170 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Impact of Light Touch and Pin Prick on Functional Outcomes in Patients with Traumatic Spinal Cord Injury en-subtitle= kn-subtitle= en-abstract= kn-abstract=A spinal cord injury (SCI) can cause severe lifelong functional disability and profoundly affect an individual’s daily life. We investigated the prediction of patients’ post-SCI functional outcomes by evaluating sensory scores rather than motor scores, as the latter’s association with functional outcomes is well established. We examined patients’ responses to a light touch (LT) and pin prick (PP) at admission and the response data’s usefulness as predictors of functional outcomes (i.e., ability to perform activities of daily living) at discharge. This exploratory observational study used data from the Japanese National Spinal Cord Injury Database (SCI-J). Data from 3,676 patients who met the inclusion criteria and were admitted for an SCI between 1997 and 2020 were analyzed. The motor score of the Functional Independence Measure (mFIM) at discharge was used as an index of functional outcome. A multiple regression analysis revealed that the mFIM was associated with both the LT response (β=0.07 (0.01), p<0.001) and the PP response (β=0.07 (0.01), p<0.001) at admission. The false discovery rate log-worth values for LT and PP were 6.6 and 8.5, respectively. Our findings demonstrate that LT and PP scores at admission can help predict patients’ functional outcomes after an SCI, although the magnitude of their contributions is not high. en-copyright= kn-copyright= en-aut-name=DeguchiTakayuki en-aut-sei=Deguchi en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KandaKanae en-aut-sei=Kanda en-aut-mei=Kanae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FurusawaKazunari en-aut-sei=Furusawa en-aut-mei=Kazunari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=Nlandu Roger Ngatu en-aut-sei=Nlandu Roger Ngatu en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HiraoTomohiro en-aut-sei=Hirao en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Rehabilitation, Kagawa Rosai Hospital kn-affil= affil-num=2 en-affil=Department of Public Health, Faculty of Medicine, Kagawa University kn-affil= affil-num=3 en-affil=Department of Rehabilitation Medicine, Kibikogen Rehabilitation Center for Employment Injuries kn-affil= affil-num=4 en-affil=Department of Public Health, Faculty of Medicine, Kagawa University kn-affil= affil-num=5 en-affil=Department of Public Health, Faculty of Medicine, Kagawa University kn-affil= en-keyword=functional independence measure kn-keyword=functional independence measure en-keyword=light touch kn-keyword=light touch en-keyword=pin prick kn-keyword=pin prick en-keyword=spinal cord injury kn-keyword=spinal cord injury en-keyword=Japanese National Spinal Cord Injury Database kn-keyword=Japanese National Spinal Cord Injury Database END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=2 article-no= start-page=143 end-page=149 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Impact of Travel Distance on Surgical Outcomes of Patients Surgically Treated for Non-Small Cell Lung Cancer: A Single-Center Study in Ehime, Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Travel burden is a poor prognostic factor for many cancers worldwide because it hinders optimal diagnosis and treatment planning. Currently, the impact of travel burden on survival after surgery for non-small cell lung cancer (NSCLC) in Japan is largely unexplored. We examined the impact of travel distance on the postoperative outcomes of patients with NSCLC in Ehime Prefecture, Japan. The data of 1212 patients who underwent surgical resection for NSCLC were retrospectively reviewed. Patients were divided into quartiles based on the travel distance from their home to the hospital (? 13 km, 13-40 km, 40-57 km, and > 57 km) in Ehime Prefecture. We found no significant differences among the quartiles in baseline clinicopathological characteristics, including sex, smoking status, histology, surgical procedure, clinical stage, and pathological stage. Overall survival (OS) and relapse-free survival (RFS) also were not significantly different among the travel distance quartiles. We conclude that travel distance did not impact OS or RFS among patients with NSCLC who underwent surgical resection at our institution. en-copyright= kn-copyright= en-aut-name=ShigematsuHisayuki en-aut-sei=Shigematsu en-aut-mei=Hisayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamashitaNatsumi en-aut-sei=Yamashita en-aut-mei=Natsumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SuehisaHiroshi en-aut-sei=Suehisa en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UenoTsuyoshi en-aut-sei=Ueno en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=RyukoTsuyoshi en-aut-sei=Ryuko en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SugiharaTakahito en-aut-sei=Sugihara en-aut-mei=Takahito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakashimaShohei en-aut-sei=Nakashima en-aut-mei=Shohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SanoYoshifumi en-aut-sei=Sano en-aut-mei=Yoshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YamashitaMotohiro en-aut-sei=Yamashita en-aut-mei=Motohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Thoracic Surgery, NHO Shikoku Cancer Center kn-affil= affil-num=2 en-affil=Clinical Research Center, NHO Shikoku Cancer Center kn-affil= affil-num=3 en-affil=Department of Thoracic Surgery, NHO Shikoku Cancer Center kn-affil= affil-num=4 en-affil=Department of Thoracic Surgery, NHO Shikoku Cancer Center kn-affil= affil-num=5 en-affil=Department of Thoracic Surgery, NHO Shikoku Cancer Center kn-affil= affil-num=6 en-affil=Department of Thoracic Surgery, NHO Shikoku Cancer Center kn-affil= affil-num=7 en-affil=Department of Thoracic Surgery, NHO Shikoku Cancer Center kn-affil= affil-num=8 en-affil=Department of Cardiovascular and Thoracic Surgery, Ehime University Graduate School of Medicine kn-affil= affil-num=9 en-affil=Department of Thoracic Surgery, NHO Shikoku Cancer Center kn-affil= en-keyword=non-small cell lung cancer kn-keyword=non-small cell lung cancer en-keyword=travel distance kn-keyword=travel distance en-keyword=travel burden kn-keyword=travel burden en-keyword=lung surgery kn-keyword=lung surgery en-keyword=surgical outcome kn-keyword=surgical outcome END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=7 article-no= start-page=1886 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Prospective Observational Study on Gastric Endoscopic Submucosal Dissection under Continuous Administration of Antithrombotic Agents en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: This study aimed to assess the completion rate and postoperative bleeding incidence of endoscopic submucosal dissection (ESD) for gastric tumors under continuous antithrombotic therapy. Methods: A prospective observational study was conducted including 88 patients with 100 gastric lesions who underwent gastric endoscopic submucosal dissection (ESD) and received continuous antithrombotic therapy. Additionally, retrospective data on gastric ESD in 479 patients with 534 lesions who did not receive antithrombotic therapy were collected for comparison. Results: The en bloc resection rates (100% in the continuous antithrombotic therapy group vs. 100% in the non-antithrombotic therapy group) and complete resection rates (97.0% vs. 96.3%, respectively) were high and comparable between the groups. No significant differences were found in the specimen size or procedure time. Perforation rates were low (0% vs. 2.3%, respectively) and were not significantly different between the groups. However, postoperative bleeding occurred significantly more frequently in the continuous antithrombotic therapy group (10.2% vs. 4.2%, respectively) than in the non-antithrombotic therapy group. The subgroup analysis revealed a higher incidence of postoperative bleeding in patients receiving thienopyridine derivatives. Conclusions: Continuous administration of antithrombotic agents, especially thienopyridines, increased the risk of postprocedural hemorrhage following gastric ESD. These findings support the need for careful consideration of pharamcological management before ESD, aligning with the current guidelines. en-copyright= kn-copyright= en-aut-name=KawaiDaisuke en-aut-sei=Kawai en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakenakaRyuta en-aut-sei=Takenaka en-aut-mei=Ryuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ObataTaisuke en-aut-sei=Obata en-aut-mei=Taisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamamotoTakashi en-aut-sei=Yamamoto en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HirataShoichiro en-aut-sei=Hirata en-aut-mei=Shoichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MiuraKo en-aut-sei=Miura en-aut-mei=Ko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakemotoKoji en-aut-sei=Takemoto en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TsugenoHirofumi en-aut-sei=Tsugeno en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=FujikiShigeatsu en-aut-sei=Fujiki en-aut-mei=Shigeatsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Gastroenterology, Tsuyama Chuo Hospital kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterology, Tsuyama Chuo Hospital kn-affil= affil-num=4 en-affil=Department of Gastroenterology, Tsuyama Chuo Hospital kn-affil= affil-num=5 en-affil=Department of Gastroenterology, Tsuyama Chuo Hospital kn-affil= affil-num=6 en-affil=Department of Gastroenterology, Tsuyama Chuo Hospital kn-affil= affil-num=7 en-affil=Department of Gastroenterology, Tsuyama Chuo Hospital kn-affil= affil-num=8 en-affil=Department of Gastroenterology, Tsuyama Chuo Hospital kn-affil= affil-num=9 en-affil=Department of Gastroenterology, Tsuyama Chuo Hospital kn-affil= affil-num=10 en-affil=Department of Gastroenterology, Tsuyama Chuo Hospital kn-affil= en-keyword=endoscopic submucosal dissection kn-keyword=endoscopic submucosal dissection en-keyword=antithrombotic agents kn-keyword=antithrombotic agents en-keyword=thienopyridine kn-keyword=thienopyridine en-keyword=gastric tumor kn-keyword=gastric tumor en-keyword=postoperative bleeding kn-keyword=postoperative bleeding en-keyword=delayed bleeding kn-keyword=delayed bleeding END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=2 article-no= start-page=95 end-page=106 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Roles of Neuropeptide Y in Respiratory Disease Pathogenesis via the Airway Immune Response en-subtitle= kn-subtitle= en-abstract= kn-abstract=The lungs are very complex organs, and the respiratory system performs the dual roles of repairing tissue while protecting against infection from various environmental stimuli. Persistent external irritation disrupts the immune responses of tissues and cells in the respiratory system, ultimately leading to respiratory disease. Neuropeptide Y (NPY) is a 36-amino-acid polypeptide and a neurotransmitter that regulates homeostasis. The NPY receptor is a seven-transmembrane-domain G-protein-coupled receptor with six subtypes (Y1, Y2, Y3, Y4, Y5, and Y6). Of these receptors, Y1, Y2, Y4, and Y5 are functional in humans, and Y1 plays important roles in the immune responses of many organs, including the respiratory system. NPY and the Y1 receptor have critical roles in the pathogenesis of asthma, chronic obstructive pulmonary disease, and idiopathic pulmonary fibrosis. The effects of NPY on the airway immune response and pathogenesis differ among respiratory diseases. This review focuses on the involvement of NPY in the airway immune response and pathogenesis of various respiratory diseases. en-copyright= kn-copyright= en-aut-name=ItanoJunko en-aut-sei=Itano en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KiuraKatsuyuki en-aut-sei=Kiura en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyaharaNobuaki en-aut-sei=Miyahara en-aut-mei=Nobuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= en-keyword=neuropeptide y kn-keyword=neuropeptide y en-keyword=Y1 receptor kn-keyword=Y1 receptor en-keyword=airway immune response kn-keyword=airway immune response en-keyword=bronchial epithelial cells kn-keyword=bronchial epithelial cells en-keyword=respiratory disease kn-keyword=respiratory disease END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=1 article-no= start-page=251 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Comparison of early clinical outcome in carpal tunnel release - mini-open technique with palmar incision vs. endoscopic technique with wrist crease incision- en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background The purpose of this study was to examine two techniques for Carpal Tunnel Syndrome, mini-Open Carpal Tunnel Release (mini-OCTR) and Endoscopic Carpal Tunnel Release (ECTR), to compare their therapeutic efficacy.
Methods Sixteen patients who underwent mini-OCTR in palmar incision and 17 patients who underwent ECTR in the wrist crease incision were included in the study. All patients presented preoperatively and at 1, 3, and 6 months postoperatively and were assessed with the Visual Analogue Scale (VAS) and the Disabilities of Arm, Shoulder and Hand Score (DASH). We also assessed the pain and cosmetic VAS of the entire affected hand or surgical wound, and the patient's satisfaction with the surgery.
Results In the objective evaluation, both surgical techniques showed improvement at 6 months postoperatively. The DASH score was significantly lower in the ECTR group (average = 3 months: 13.6, 6 months: 11.9) than in the mini-OCTR group (average = 3 months: 27.3, 6 months: 20.6) at 3 and 6 months postoperatively. Also, the pain VAS score was significantly lower in the ECTR group (average = 17.1) than in the mini-OCTR group (average = 36.6) at 3 months postoperatively. The cosmetic VAS was significantly lower in the ECTR group (average = 1 month: 15.3, 3 months: 12.2, 6 months: 5.41) than in the mini-OCTR group (average = 1 month: 33.3, 3 months: 31.2, 6 months: 24.8) at all time points postoperatively. Patient satisfaction scores tended to be higher in the ECTR group (average = 3.3) compared to the mini-OCTR group (average = 2.7).
Conclusions ECTR in wrist increase incision resulted in better pain and cosmetic recovery in an early postoperative phase compared with mini-OCTR in palmar incision. Our findings suggest that ECTR is an effective technique for patient satisfaction. en-copyright= kn-copyright= en-aut-name=NakamichiRyo en-aut-sei=Nakamichi en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SaitoTaichi en-aut-sei=Saito en-aut-mei=Taichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShimamuraYasunori en-aut-sei=Shimamura en-aut-mei=Yasunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HamadaMasanori en-aut-sei=Hamada en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishidaKeiichiro en-aut-sei=Nishida en-aut-mei=Keiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Rehabilitation Medicine, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Sports Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Sports Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Department of Rehabilitation Medicine, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Sports Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of Sports Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= en-keyword=Carpal tunnel syndrome kn-keyword=Carpal tunnel syndrome en-keyword=Mini-open kn-keyword=Mini-open en-keyword=Endoscopy kn-keyword=Endoscopy en-keyword=Patient-oriented evaluation kn-keyword=Patient-oriented evaluation END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=2 article-no= start-page=e0297347 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240208 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Japan-epiretinal membrane (J-ERM) registry: A prospective cohort study protocol investigating the surgical outcome of epiretinal membrane en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
Epiretinal membrane (ERM) causes visual impairment such as reduction in visual acuity and metamorphopsia due to retinal traction. With the improvement of optical coherence tomography (OCT) and microincision vitrectomy surgery (MIVS), the surgery of ERM has significantly advanced. However, there have been no large-scale studies on the following: (1) how to evaluate visual impairment in ERM, (2) the relationship between OCT findings and visual function, (3) when is the optimal timing of surgery, and (4) the relationship between the surgical instruments as well as techniques and prognosis. The purpose of this study was to obtain evidence regarding these ERM surgeries.
Methods and design
This is a prospective, multicenter cohort study of ERM surgery in Japan from March 1, 2023, to March 31, 2027 (UMIN000048472, R-3468-2). Patients who underwent ERM surgery during the study period and agreed to participate in this study will be included. The goal is to have a total of 5,000 eyes surgically treated for ERM.

Bicontinuous interfacially jammed emulsion gels represent a unique class of soft matter formed by kinetically arresting the separation of the spinodal decomposition phase, which is stabilized by colloidal particles with neutral wetting. This study introduces a microfluidic technique to create highly interconnected open-porous particles using bijel droplets stabilized with hexadecyltrimethylammonium bromide (CTAB)-modified silica particles. Monodisperse droplets comprising a hydrophobic monomer, water, ethanol, silica particles, and CTAB were initially formed in the microfluidic device. The diffusion of ethanol from these droplets into the continuous cyclohexane phase triggered spinodal decomposition within the droplets. The phase-separated structure within the droplets was stabilized by the CTAB-modified silica particles, and subsequent photopolymerization yielded microparticles with highly interconnected, open pores. Moreover, the influence of the ratio of the CTAB and silica particles, fluid composition, and microchannel direction on the final structure of the microparticles was explored. Our findings indicated that the phase-separated structure of the particles transitioned from oil-in-water to water-in-oil as the CTAB/silica ratio was increased. At intermediate CTAB/silica ratios, microparticles with bicontinuous structures were formed. Regardless of the fluid composition, the pore size of the particles increased with time after phase separation. However, this coarsening was arrested 15 s after droplet formation in the CTAB-modified silica particles, accompanied by a change in the particle shape from spherical to ellipsoidal. In situ observations of the bijel droplet formation revealed that the particle shape deformation is caused by the rolling of elastic bijel droplets at the bottom of the microchannel. As such, the channel setup was altered from horizontal to vertical to prevent the deformation of bijel droplets, resulting in spherical particles with open pores. en-copyright= kn-copyright= en-aut-name=MasaokaMina en-aut-sei=Masaoka en-aut-mei=Mina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IshidaHiroaki en-aut-sei=Ishida en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WatanabeTakaichi en-aut-sei=Watanabe en-aut-mei=Takaichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OnoTsutomu en-aut-sei=Ono en-aut-mei=Tsutomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Department of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Department of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Department of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=1 cd-vols= no-issue= article-no= start-page=106 end-page=121 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240314 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Exploring the dynamics of change in students’ English proficiency and self-evaluations: The analysis of GTEC scores and Okadai CAN-DO List across required English courses kn-title=必修英語科目コース別の英語力と自己評価の変化－GTECスコアと岡大CAN-DO リストを用いて－ en-subtitle= kn-subtitle= en-abstract=This paper presents a quantitative analysis of two compulsory English curricula?a 6-credit course and an 8-credit course?with a focus on the skills of reading and speaking.

The results of the GTEC test showed that the mean of the 6-credit course (about 580 survey participants) was statistically higher than that of the 8-credit course (about 450 survey participants) for both skills at the end of the course than at the time of entering university. On the other hand, in the CAN-DO list responses, regardless of the course, the mean values for the less difficult Reading items fell below the mean values at the time of entering university, whereas the mean values for the more difficult CAN-DO items increased at the end of the course.

However, despite these efforts, the total number of bullying cases is not decreasing. This study aims to enhance the effectiveness of the questionnaires. Fourteen bullying questionnaires developed by the board of education were collected and analyzed. We found they used very similar definitions about actions as bullying. However, Miyagawa and Aoki (2023) suggested the possibility that the most serious forms of bullying for students involve actions from which they could not do the same action at the same time. Therefore, we investigated whether teachers recognized the seriousness of such actions. Seventyfive teachers from high school to elementary school participated in this study. Consequently, we found that teachers recognized bullying that “could not return back” as more serious than actions that “could return back.” Based on these results, it would be possible to say that “the actions of bullying,” as using the questionnaires by the board of education now are adequate for a survey. However, these findings also imply limitations in the effectiveness of early bullying detection by the questionnaires. Potential modifications to the questionnaires were discussed to address these limitations and take precautions against such possibilities. kn-abstract=　いじめ早期発見を目的としたアンケートが全国で実施されているが，いじめの認知件数は減少していない。そこで，全国14都道府県のいじめアンケートを集計し，内容を分析した。加えて，このいじめアンケートが「いじめに該当する」としている行為に着目し，いじめ行為に対する，教師の「いじめに対する深刻さの認識」を調査した。その際，宮川・青木（2023）が示した「いじめの深刻度」に関する知見を用いた。分析の結果，教師は「やり返せる行為」よりも，「やり返せない行為」をより深刻と捉えていることがわかった。つまり，教師は「深刻と捉えられるべきいじめ行為」を深刻だと捉えており，現行いじめアンケートが「いじめに該当する」としている行為は妥当であると考えた。このことは，現行いじめアンケートでは早期発見が難しいことを示唆している。よって，早期発見と言うよりは，未然防止につながる新しいアンケートの開発の必要性について考察した。 en-copyright= kn-copyright= en-aut-name=MIYAGAWASena en-aut-sei=MIYAGAWA en-aut-mei=Sena kn-aut-name=宮川世名 kn-aut-sei=宮川 kn-aut-mei=世名 aut-affil-num=1 ORCID= en-aut-name=AOKITazuko en-aut-sei=AOKI en-aut-mei=Tazuko kn-aut-name=青木多寿子 kn-aut-sei=青木 kn-aut-mei=多寿子 aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Education，Okayama University (Master Degree Course) kn-affil=岡山大学大学院教育学研究科大学院生 affil-num=2 en-affil=Faculty of Education，Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=いじめアンケート (questionnaire to detect bullying early) kn-keyword=いじめアンケート (questionnaire to detect bullying early) en-keyword=いじめ未然防止 (preventing bullying in advance) kn-keyword=いじめ未然防止 (preventing bullying in advance) en-keyword=いじめに該当する行為 (what are the ser ious actions of bullying) kn-keyword=いじめに該当する行為 (what are the ser ious actions of bullying) en-keyword=教師の認識 (recognition of bullying by teachers) kn-keyword=教師の認識 (recognition of bullying by teachers) END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue= article-no= start-page=165 end-page=175 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240329 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Differences between China and Japan in high school teachers’ career guidance policy on students: Career decision, self-efficacy and time perspective kn-title=高校教師の進路指導方針と生徒への影響に関する中日比較 ―進路決定自己効力感，時間的展望を中心に― en-subtitle= kn-subtitle= en-abstract=　Researchers have identified differences in teachers’ career guidance counseling between China and Japan.

Some interesting techniques for WLAN systems are flexible allocation of frequency resource and cognitive radio (CR) techniques which expect to find more useful spectrum resource by modeling and then predicting of channel status using the captured statistics information of the used spectrum. This paper investigates the prediction accuracy of busy/idle duration of two major wireless services: audio service and video service using neural network based predictor. We first study the statistics distribution of their time-series busy/idle (B/I) duration, and then analyze the predictability of the busy/idle duration based on the predictability theory. Then, we propose a data categorization (DC) method which categorizes the duration of recent B/I duration according the their ranges to make the duration of next data be distributed into several streams. From the predictability analysis of each stream and the prediction performance using the probabilistic neural network (PNN), it can be confirmed that the proposed DC can improve the prediction accuracy of time-series data in partial streams. en-copyright= kn-copyright= en-aut-name=HouYafei en-aut-sei=Hou en-aut-mei=Yafei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DennoSatoshi en-aut-sei=Denno en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Wireless LAN kn-keyword=Wireless LAN en-keyword=Wireless communication kn-keyword=Wireless communication en-keyword=Media streaming kn-keyword=Media streaming en-keyword=Wireless sensor networks kn-keyword=Wireless sensor networks en-keyword=Resource management kn-keyword=Resource management en-keyword=Probability distribution kn-keyword=Probability distribution en-keyword=Channel allocation kn-keyword=Channel allocation en-keyword=Audio-visual systems kn-keyword=Audio-visual systems en-keyword=Data processing kn-keyword=Data processing en-keyword=Predictive models kn-keyword=Predictive models en-keyword=Neural networks kn-keyword=Neural networks en-keyword=Channel status duration prediction kn-keyword=Channel status duration prediction en-keyword=WLAN audio/video traffic kn-keyword=WLAN audio/video traffic en-keyword=data predictability analysis kn-keyword=data predictability analysis en-keyword=probabilistic neural network (PNN) kn-keyword=probabilistic neural network (PNN) END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=2 article-no= start-page=102 end-page=109 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240221 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Treatment interruption in hypertensive patients during the COVID-19 pandemic: An interrupted time series analysis using prescription data in Okayama, Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: The COVID- 19 pandemic has impacted healthcare behaviors, leading to fewer pediatric visits in Japan and potentially fewer visits by adult patients. However, existing Japanese studies on treatment interruptions have generally relied on questionnaire- based methods. In this study, we assessed the impact of the pandemic on antihypertensive treatment interruption using real- world prescription data.
Methods: We conducted an interrupted time series analysis using the National Health Insurance Database in Okayama Prefecture, Japan. Participants included individuals aged 40-69 years with at least one antihypertensive prescription between 2018 and 2020. Treatment interruption was defined as a 3- month or longer gap in prescriptions after medication depletion. We used segmented Poisson regression with models unadjusted and adjusted for seasonality and over- dispersion to assess monthly treatment interruptions before and after Japan's April 2020 emergency.
Results: During the study period, 23.0% of 55,431 participants experienced treatment interruptions. Cyclical fluctuations in interruptions were observed. The crude analysis indicated a 1.2 - fold increase in treatment interruptions following the pandemic; however, the adjusted models showed no significant changes. Even among higher- risk groups, such as women, younger adults, and those with shorter prescriptions, no significant alterations were observed.
Conclusion: We found no significant impact of the COVID- 19 pandemic on antihypertensive treatment interruption in Okayama Prefecture. The less severe outbreak in the area or increased use of telemedicine and extended prescriptions may have contributed to treatment continuity. Further research is needed using a more stable and comprehensive database, broader regional data, and detailed prescription records to validate and extend our findings. en-copyright= kn-copyright= en-aut-name=NakamuraNaoko en-aut-sei=Nakamura en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsumotoNaomi en-aut-sei=Matsumoto en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HayaseShunsaku en-aut-sei=Hayase en-aut-mei=Shunsaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Academic Affairs Division, Okayama University kn-affil= affil-num=5 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=antihypertensive agents kn-keyword=antihypertensive agents en-keyword=COVID-19 kn-keyword=COVID-19 en-keyword=health behavior kn-keyword=health behavior en-keyword=interrupted time series analysis kn-keyword=interrupted time series analysis en-keyword=prescription drugs kn-keyword=prescription drugs en-keyword=treatment interruption kn-keyword=treatment interruption END start-ver=1.4 cd-journal=joma no-vol=150 cd-vols= no-issue=2 article-no= start-page=89 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinical characteristics of patients treated with immune checkpoint inhibitors in EGFR-mutant non-small cell lung cancer: CS-Lung-003 prospective observational registry study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose Immune checkpoint inhibitors (ICIs) are ineffective against epidermal growth factor receptor (EGFR)-mutant non-small cell lung cancer (NSCLC). This study aimed to investigate the clinical characteristics of patients who were treated or not treated with ICIs, and of those who benefit from immunotherapy in EGFR-mutant NSCLC.
Methods We analyzed patients with unresectable stage III/IV or recurrent NSCLC harboring EGFR mutations using a prospective umbrella-type lung cancer registry (CS-Lung-003).
Results A total of 303 patients who met the eligibility criteria were analyzed. The median age was 69 years; 116 patients were male, 289 had adenocarcinoma, 273 had major mutations, and 67 were treated with ICIs. The duration of EGFR-TKI treatment was longer in the Non-ICI group than in the ICI group (17.1 vs. 12.7 months, p? Conclusion ICIs were administered to only 22% of patients with EGFR-mutated lung cancer, and they had shorter TTNT of EGFR-TKI compared to other patients. ICI treatment should be avoided in EGFR mutated lung cancer with poor PS but can be considered for lung cancer with EGFR minor mutations. Pathological biomarker to predict long-term responders to ICI are needed.

kn-abstract=Purpose The purpose of this study is to confirm whether it is possible to acquire a certain degree of diagnostic ability even with a small dataset using domain-specific transfer learning. In this study, we constructed a simulated caries detection model on panoramic tomography using transfer learning.
Methods A simulated caries model was trained and validated using 1094 trimmed intraoral images. A convolutional neural network (CNN) with three convolution and three max pooling layers was developed. We applied this caries detection model to 50 panoramic images and evaluated its diagnostic performance.
Results The diagnostic performance of the CNN model on the intraoral film was as follows: C0 84.6%; C1 90.6%; C2 88.6%. Finally, we tested 50 panoramic images with simulated caries insertion. The diagnostic performance of the CNN model on the panoramic image was as follows: C0 75.0%, C1 80.0%, C2 80.0%, and overall diagnostic accuracy was 78.0%. The diagnostic performance of the caries detection model constructed only with panoramic images was much lower than that of the intraoral film.
Conclusion Domain-specific transfer learning methods may be useful for saving datasets and training time (179/250). en-copyright= kn-copyright= en-aut-name=KawazuToshiyuki en-aut-sei=Kawazu en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakeshitaYohei en-aut-sei=Takeshita en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujikuraMamiko en-aut-sei=Fujikura en-aut-mei=Mamiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OkadaShunsuke en-aut-sei=Okada en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HisatomiMiki en-aut-sei=Hisatomi en-aut-mei=Miki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AsaumiJunichi en-aut-sei=Asaumi en-aut-mei=Junichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Oral and Maxillofacial Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Oral and Maxillofacial Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral Diagnosis and Dentomaxillofacial Radiology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Oral Diagnosis and Dentomaxillofacial Radiology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Oral Diagnosis and Dentomaxillofacial Radiology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Oral and Maxillofacial Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Deep neural networks kn-keyword=Deep neural networks en-keyword=Caries detection kn-keyword=Caries detection en-keyword=Domain-Specific transfer learning kn-keyword=Domain-Specific transfer learning en-keyword=Panoramic tomography kn-keyword=Panoramic tomography END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=1 article-no= start-page=85 end-page=88 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202402 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Case of Idiopathic Peptic Ulcer Disease Treated Effectively with Trimebutine Maleat en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 30-year-old man with idiopathic peptic ulcer disease (IPUD) experienced repeated recurrence of ulcerative bleeding despite treatment with lansoprazole and then vonoprazan. Further evaluation suggested that the cause of the ulcer was strong contractile movements of the antrum. This prompted the co-administration of trimebutine maleate (TM) and vonoprazan to relieve the stomach contractions. TM was effective in preventing the recurrence of ulcerative bleeding, and the patient has remained in remission for 4 years. This case highlights the potential efficacy of TM in treating IPUD and the importance of considering hypercontractility as the underlying cause in cases of IPUD. en-copyright= kn-copyright= en-aut-name=MiyakeKeisuke en-aut-sei=Miyake en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanikawaTomohiro en-aut-sei=Tanikawa en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HarumaKen en-aut-sei=Haruma en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KawadaMayuko en-aut-sei=Kawada en-aut-mei=Mayuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IshiiKatsunori en-aut-sei=Ishii en-aut-mei=Katsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UrataNoriyo en-aut-sei=Urata en-aut-mei=Noriyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NishinoKen en-aut-sei=Nishino en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SuehiroMitsuhiko en-aut-sei=Suehiro en-aut-mei=Mitsuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KawanakaMiwa en-aut-sei=Kawanaka en-aut-mei=Miwa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ManabeNoriaki en-aut-sei=Manabe en-aut-mei=Noriaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KawamotoHirofumi en-aut-sei=Kawamoto en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Post graduate clinical education center, Kawasaki Medical School General Medical Center kn-affil= affil-num=2 en-affil=Department of General Internal Medicine 2, Kawasaki Medical School kn-affil= affil-num=3 en-affil=Department of General Internal Medicine 2, Kawasaki Medical School kn-affil= affil-num=4 en-affil=Department of General Internal Medicine 2, Kawasaki Medical School kn-affil= affil-num=5 en-affil=Department of General Internal Medicine 2, Kawasaki Medical School kn-affil= affil-num=6 en-affil=Department of General Internal Medicine 2, Kawasaki Medical School kn-affil= affil-num=7 en-affil=Department of General Internal Medicine 2, Kawasaki Medical School kn-affil= affil-num=8 en-affil=Department of General Internal Medicine 2, Kawasaki Medical School kn-affil= affil-num=9 en-affil=Department of General Internal Medicine 2, Kawasaki Medical School kn-affil= affil-num=10 en-affil=Division of Endoscopy and Ultrasonography, Department of Clinical Pathology and Laboratory Medicine, Kawasaki Medical School kn-affil= affil-num=11 en-affil=Department of General Internal Medicine 2, Kawasaki Medical School kn-affil= en-keyword=gastric ulcer kn-keyword=gastric ulcer en-keyword=idiopathic peptic ulcerative disease kn-keyword=idiopathic peptic ulcerative disease en-keyword=trimebutine maleate kn-keyword=trimebutine maleate END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=1 article-no= start-page=53 end-page=61 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202402 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Quantitative Assessment of the Heat Transfer Capacity of Ice Bags and their Cooling Effects on the Skin Surface and Core Temperature en-subtitle= kn-subtitle= en-abstract= kn-abstract=Ice bags are frequently used in medical care settings for pain relief, comfort, and in some cases, whole-body cooling. This study quantifies heat energy transfer capacity of ice bags and evaluates their cooling effects on body temperature. Forty-eight healthy adults in their 20s were recruited. An ice bag wrapped in two layers of dry towel was applied to the forehead, neck, or palm of each participant for 10 min. The skin surface temperature, heat flow, and core temperature were recorded during the cooling and non-cooling periods, with energy transfer calculated by integrating heat flow over time. Over the non-cooling period, 31.4-53.6 kJ?m-2 of energy was dissipated over 10 min, whereas during the cooling period, the range increased to 180.0-218.7 kJ?m-2 over 10 min. Skin surface temperature decreased by 3.2-5.7°C, whereas core temperature was unchanged. Ice bag use augmented energy transfer by about 150-180 kJ?m-2 over 10 min, but this was insufficient for rapid whole body cooling due to the small skin-surface area in contact with the ice bag. The measured energy transfer indicated that topical ice bag application absorbs insufficient energy to affect core temperature. Quantitative assessment of energy transfer was shown to inform the safe and appropriate use of thermotherapy. en-copyright= kn-copyright= en-aut-name=IchikawaYukiko en-aut-sei=Ichikawa en-aut-mei=Yukiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OginoTetsuya en-aut-sei=Ogino en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Nursing Science, Faculty of Health and Welfare Science, Okayama Prefectural University kn-affil= affil-num=2 en-affil=Department of Nursing Science, Faculty of Health and Welfare Science, Okayama Prefectural University kn-affil= en-keyword=cold compress kn-keyword=cold compress en-keyword=fever kn-keyword=fever en-keyword=hyperthermia kn-keyword=hyperthermia en-keyword=thermal conductivity kn-keyword=thermal conductivity en-keyword=thermoregulation kn-keyword=thermoregulation END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=1 article-no= start-page=47 end-page=52 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202402 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Long-Term Follow-up Data of a Multi-Institutional Phase-2 Study of S-1/oxaliplatin and Bevacizumab Therapy in Patients with Advanced Colorectal Cancer: The HiSCO-02 Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Oral fluoropyrimidines (FUs) have certain advantages over intravenous FUs, such as longer intervals between outpatient visits, no requirement for central venous port (CVP) implantation, and lower incidence of neutropenia. We previously reported the efficacy of S-1/oxaliplatin (SOX) with bevacizumab therapy as a first-line treatment for advanced colorectal cancer (CRC) in a prospective phase-II multi-institutional clinical trial (HiSCO-02 study). However, our prognostic data at the time lacked a sufficient observation period. Herein, we analyze the longer-term follow-up data, focusing on the status of eventual CVP implantation via an open-label, non-randomized, multicenter study. This study enrolled 55 patients (mean age, 64 years), of whom 43 died (41 of primary cancer). The median overall survival was 22.7 months (95% CI: 20.1-34.7 months). Post-treatment regimens after failure of first-line treatment were initiated in 43 patients; CPT11-based regimens were selected in most cases, and other oral FU combinations in nine. CVP was implanted in 35 patients prior to first-line treatment; eleven of the remaining 20 patients did not require CVP implantation. In conclusion, we report here the final prognostic update of the Phase II clinical trial examining the efficacy of SOX plus bevacizumab therapy, the results of which confirm the clinical efficacy of this regimen. en-copyright= kn-copyright= en-aut-name=ShimomuraManabu en-aut-sei=Shimomura en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShinozakiKatsunori en-aut-sei=Shinozaki en-aut-mei=Katsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YanoTakuya en-aut-sei=Yano en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AkabaneShintaro en-aut-sei=Akabane en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OhdanHideki en-aut-sei=Ohdan en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=Hiroshima Surgical study group of Clinical Oncology (HiSCO) en-aut-sei=Hiroshima Surgical study group of Clinical Oncology (HiSCO) en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Gastroenterological and Transplant Surgery, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=2 en-affil=Division of Clinical Oncology, Hiroshima Prefectural Hospital kn-affil= affil-num=3 en-affil=Department of Gastroenterological and Transplant Surgery, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=4 en-affil=Department of Gastroenterological and Transplant Surgery, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=5 en-affil=Department of Gastroenterological and Transplant Surgery, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=6 en-affil= kn-affil= en-keyword=metastatic colorectal cancer kn-keyword=metastatic colorectal cancer en-keyword=chemotherapy kn-keyword=chemotherapy en-keyword=S-1 kn-keyword=S-1 en-keyword=prospective phase II study kn-keyword=prospective phase II study END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=1 article-no= start-page=37 end-page=46 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202402 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Is Proximal Triangular Fixation Better than the Conventional Method in Adult Spinal Deformity Surgery? en-subtitle= kn-subtitle= en-abstract= kn-abstract=In adult spinal deformity (ASD) surgery, one of the key factors working to prevent proximal junctional kyphosis is the proximal anchor. The aim of this study was to compare clinical and radiographic outcomes of triangular fixation with conventional fixation as proximal anchoring techniques in ASD surgery. We retrospectively evaluated 54 patients who underwent corrective spinal fusion for ASD. Fourteen patients underwent proximal triangular fixation (Group T; average 74.6 years), and 40 patients underwent the conventional method (Group C; average 70.5 years). Clinical and radiographic outcomes were assessed using visual analogue scale (VAS) values for back pain and the Oswestry disability index (ODI). Radiographic evaluation was also collected preoperatively and postoperatively. Surgical times and intraoperative blood loss of the two groups were not significantly different (493 vs 490 min, 1,260 vs 1,173 mL). Clinical outcomes such as VAS and ODI were comparable in the two groups. Proximal junctional kyphosis in group T was slightly lower than that of group C (28.5% vs 47.5%, p=0.491). However, based on radiology, proximal screw pullout occurred significantly less frequently in the triangular fixation group than the conventional group (0.0% vs 22.5%, p=0.049). Clinical outcomes in the two groups were not significantly different. en-copyright= kn-copyright= en-aut-name=TanakaMasato en-aut-sei=Tanaka en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MeenaUmesh en-aut-sei=Meena en-aut-mei=Umesh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TaokaTakuya en-aut-sei=Taoka en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujiwaraYoshihiro en-aut-sei=Fujiwara en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YokomizoDaiichiro en-aut-sei=Yokomizo en-aut-mei=Daiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=BashyalSantosh Kumar en-aut-sei=Bashyal en-aut-mei=Santosh Kumar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SakeNaveen en-aut-sei=Sake en-aut-mei=Naveen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AratakiShinya en-aut-sei=Arataki en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= en-keyword=adult spinal deformity kn-keyword=adult spinal deformity en-keyword=proximal junctional kyphosis kn-keyword=proximal junctional kyphosis en-keyword=triangular fixation kn-keyword=triangular fixation en-keyword=minimally invasive surgery kn-keyword=minimally invasive surgery en-keyword=C arm free kn-keyword=C arm free END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=1 article-no= start-page=1 end-page=8 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202402 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Role of Macrophages in Liver Fibrosis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Liver fibrosis, which ultimately leads to liver cirrhosis and hepatocellular carcinoma, is a major health burden worldwide. The progression of liver fibrosis is the result of the wound-healing response of liver to repeated injury. Hepatic macrophages are cells with high heterogeneity and plasticity and include tissue-resident macrophages termed Kupffer cells, and recruited macrophages derived from circulating monocytes, spleen and peritoneal cavity. Studies have shown that hepatic macrophages play roles in the initiation and progression of liver fibrosis by releasing inflammatory cytokines/chemokines and pro-fibrogenic factors. Furthermore, the development of liver fibrosis has been shown to be reversible. Hepatic macrophages have been shown to alternately regulate both the regression and turnover of liver fibrosis by changing their phenotypes during the dynamic progression of liver fibrosis. In this review, we summarize the role of hepatic macrophages in the progression and regression of liver fibrosis. en-copyright= kn-copyright= en-aut-name=SunCuiming en-aut-sei=Sun en-aut-mei=Cuiming kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsukawaAkihiro en-aut-sei=Matsukawa en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Pathology and Experimental Medicine, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pathology and Experimental Medicine, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=ERK-MAPK kn-keyword=ERK-MAPK en-keyword=SPRED2 kn-keyword=SPRED2 en-keyword=fibrosis kn-keyword=fibrosis en-keyword=macrophages kn-keyword=macrophages END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=1 article-no= start-page=2202 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240125 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Endoscopic and clinical features of gastric emphysema en-subtitle= kn-subtitle= en-abstract= kn-abstract=Gastric emphysema is characterized by the presence of intramural gas in the stomach without bacterial infection. Due to its rarity, most reports on gastric emphysema have been limited to single-case studies, and this condition's clinical and endoscopic features have not been thoroughly investigated. In this study, we analyzed 45 patients with gastric emphysema from 10 institutions and examined their characteristics, endoscopic features, and outcomes. The mean age at diagnosis of gastric emphysema in our study population (35 males and 10 females) was 68.6 years (range, 14-95 years). The top five underlying conditions associated with gastric emphysema were the placement of a nasogastric tube (26.7%), diabetes mellitus (20.0%), post-percutaneous endoscopic gastrostomy (17.8%), malignant neoplasms (17.8%), and renal failure (15.6%). Among the 45 patients, 42 were managed conservatively with fasting and administration of proton pump inhibitors. Unfortunately, seven patients died within 30 days of diagnosis, and 35 patients experienced favorable recoveries. The resolution of gastric emphysema was confirmed in 30 patients through computed tomography (CT) scans, with a mean duration of 17.1 +/- 34.9 days (mean +/- standard deviation [SD], range: 1-180 days) from the time of diagnosis to the disappearance of the gastric intramural gas. There were no instances of recurrence. Endoscopic evaluation was possible in 18 patients and revealed that gastric emphysema presented with features such as redness, erosion, coarse mucosa, and ulcers, with fewer mucosal injuries on the anterior wall (72.2%), a clear demarcation between areas of mucosal injury and intact mucosa (61.1%), and predominantly longitudinal mucosal injuries on the stomach folds (50.0%). This study is the first English-language report to analyze endoscopic findings in patients with gastric emphysema. en-copyright= kn-copyright= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakenakaRyuta en-aut-sei=Takenaka en-aut-mei=Ryuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ToyokawaTatsuya en-aut-sei=Toyokawa en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KitaMasahide en-aut-sei=Kita en-aut-mei=Masahide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TsuzukiTakao en-aut-sei=Tsuzuki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshiokaMasao en-aut-sei=Yoshioka en-aut-mei=Masao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=GotodaTatsuhiro en-aut-sei=Gotoda en-aut-mei=Tatsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OkanoueShotaro en-aut-sei=Okanoue en-aut-mei=Shotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MatsubaraMinoru en-aut-sei=Matsubara en-aut-mei=Minoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SakaguchiChihiro en-aut-sei=Sakaguchi en-aut-mei=Chihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Internal Medicine, Tsuyama Chuo Hospital kn-affil= affil-num=3 en-affil=Department of Gastroenterology, National Hospital Organization Fukuyama Medical Center kn-affil= affil-num=4 en-affil=Department of Internal Medicine, Okayama City Hospital kn-affil= affil-num=5 en-affil=Department of Internal Medicine, Japanese Red Cross Society Himeji Hospital kn-affil= affil-num=6 en-affil=Department of Internal Medicine, Okayama Saiseikai General Hospital kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Kurashiki Central Hospital kn-affil= affil-num=8 en-affil=Department of Gastroenterology, Mitoyo General Hospital kn-affil= affil-num=9 en-affil=Department of Gastroenterology, Sumitomo Besshi Hospital kn-affil= affil-num=10 en-affil=Department of Endoscopy, National Hospital Organization Shikoku Cancer Center kn-affil= affil-num=11 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=2 article-no= start-page=281 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240116 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A System for Monitoring Animals Based on Behavioral Information and Internal State Information en-subtitle= kn-subtitle= en-abstract= kn-abstract=Managing the risk of injury or illness is an important consideration when keeping pets. This risk can be minimized if pets are monitored on a regular basis, but this can be difficult and time-consuming. However, because only the external behavior of the animal can be observed and the internal condition cannot be assessed, the animal’s state can easily be misjudged. Additionally, although some systems use heartbeat measurement to determine a state of tension, or use rest to assess the internal state, because an increase in heart rate can also occur as a result of exercise, it is desirable to use this measurement in combination with behavioral information. In the current study, we proposed a monitoring system for animals using video image analysis. The proposed system first extracts features related to behavioral information and the animal’s internal state via mask R-CNN using video images taken from the top of the cage. These features are used to detect typical daily activities and anomalous activities. This method produces an alert when the hamster behaves in an unusual way. In our experiment, the daily behavior of a hamster was measured and analyzed using the proposed system. The results showed that the features of the hamster’s behavior were successfully detected. When loud sounds were presented from outside the cage, the system was able to discriminate between the behavioral and internal changes of the hamster. In future research, we plan to improve the accuracy of the measurement of small movements and develop a more accurate system. en-copyright= kn-copyright= en-aut-name=ShibanokiTaro en-aut-sei=Shibanoki en-aut-mei=Taro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamazakiYuugo en-aut-sei=Yamazaki en-aut-mei=Yuugo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TonookaHideyuki en-aut-sei=Tonooka en-aut-mei=Hideyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Intelligent Mechanical Systems, Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Major in Computer and Information Sciences, Graduate School of Science and Engineering, Ibaraki University kn-affil= affil-num=3 en-affil=Major in Computer and Information Sciences, Graduate School of Science and Engineering, Ibaraki University kn-affil= en-keyword=monitoring system kn-keyword=monitoring system en-keyword=image processing kn-keyword=image processing en-keyword=mask R-CNN kn-keyword=mask R-CNN en-keyword=anomaly detection kn-keyword=anomaly detection en-keyword=one-class SVM kn-keyword=one-class SVM en-keyword=rodents kn-keyword=rodents END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=7 article-no= start-page=1611 end-page=1619 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240118 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Controlled mechanical properties of poly(ionic liquid)-based hydrophobic ion gels by the introduction of alumina nanoparticles with different shapes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Ionic?liquid gels, also known as ion gels, have gained considerable attention due to their high ionic conductivity and CO2 absorption capacity. However, their low mechanical strength has hindered their practical applications. A potential solution to this challenge is the incorporation of particles, such as silica nanoparticles, TiO2 nanoparticles, and metal?organic frameworks (MOFs) into ion gels. Comparative studies on the effect of particles with different shapes are still in progress. This study investigated the effect of the shape of particles introduced into ion gels on their mechanical properties. Consequently, alumina/poly(ionic liquid) (PIL) double-network (DN) ion gels consisting of clustered alumina nanoparticles with various shapes (either spherical or rod-shaped) and a chemically crosslinked poly[1-ethyl-3-vinylimidazolium bis(trifluoromethanesulfonyl)imide] (PC2im-TFSI, PIL) network were prepared. The results revealed that the mechanical strengths of the alumina/PIL DN ion gels were superior to those of PIL single-network ion gels without particles. Notably, the fracture energies of the rod-shaped alumina/PIL DN ion gels were approximately 2.6 times higher than those of the spherical alumina/PIL DN ion gels. Cyclic tensile tests were performed, and the results indicate that the loading energy on the ion gel was dissipated through the fracture of the alumina network. TEM observation suggests that the variation in the mechanical strength depending on the shape can be attributed to differences in the aggregation structure of the alumina particles, thus indicating the possibility of tuning the mechanical strength of ion gels by altering not only particle kinds but its shape. en-copyright= kn-copyright= en-aut-name=MizutaniYuna en-aut-sei=Mizutani en-aut-mei=Yuna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WatanabeTakaichi en-aut-sei=Watanabe en-aut-mei=Takaichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=LopezCarlos G. en-aut-sei=Lopez en-aut-mei=Carlos G. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OnoTsutomu en-aut-sei=Ono en-aut-mei=Tsutomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Applied Chemistry, Graduate School of Natural Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Applied Chemistry, Graduate School of Natural Science, Okayama University kn-affil= affil-num=3 en-affil=Department of Materials Science and Engineering, The Pennsylvania State University kn-affil= affil-num=4 en-affil=Department of Applied Chemistry, Graduate School of Natural Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=18 article-no= start-page=14128 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230915 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Advanced Techniques Using In Vivo Electroporation to Study the Molecular Mechanisms of Cerebral Development Disorders en-subtitle= kn-subtitle= en-abstract= kn-abstract=The mammalian cerebral cortex undergoes a strictly regulated developmental process. Detailed in situ visualizations, imaging of these dynamic processes, and in vivo functional gene studies significantly enhance our understanding of brain development and related disorders. This review introduces basic techniques and recent advancements in in vivo electroporation for investigating the molecular mechanisms underlying cerebral diseases. In utero electroporation (IUE) is extensively used to visualize and modify these processes, including the forced expression of pathological mutants in human diseases; thus, this method can be used to establish animal disease models. The advent of advanced techniques, such as genome editing, including de novo knockout, knock-in, epigenetic editing, and spatiotemporal gene regulation, has further expanded our list of investigative tools. These tools include the iON expression switch for the precise control of timing and copy numbers of exogenous genes and TEMPO for investigating the temporal effects of genes. We also introduce the iGONAD method, an improved genome editing via oviductal nucleic acid delivery approach, as a novel genome-editing technique that has accelerated brain development exploration. These advanced in vivo electroporation methods are expected to provide valuable insights into pathological conditions associated with human brain disorders. en-copyright= kn-copyright= en-aut-name=YangChen en-aut-sei=Yang en-aut-mei=Chen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShitamukaiAtsunori en-aut-sei=Shitamukai en-aut-mei=Atsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YangShucai en-aut-sei=Yang en-aut-mei=Shucai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KawaguchiAyano en-aut-sei=Kawaguchi en-aut-mei=Ayano kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Human Morphology, Okayama University Graduate School of Medicine, Density and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Human Morphology, Okayama University Graduate School of Medicine, Density and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Human Anatomy and Histology and Embryology, School of Basic Medicine, Harbin Medical University kn-affil= affil-num=4 en-affil=Department of Human Morphology, Okayama University Graduate School of Medicine, Density and Pharmaceutical Sciences kn-affil= en-keyword=in vivo electroporation kn-keyword=in vivo electroporation en-keyword=in utero electroporation kn-keyword=in utero electroporation en-keyword=genome editing kn-keyword=genome editing en-keyword=IUE kn-keyword=IUE en-keyword=iON kn-keyword=iON en-keyword=TEMPO kn-keyword=TEMPO en-keyword=iGONAD kn-keyword=iGONAD END start-ver=1.4 cd-journal=joma no-vol=113 cd-vols= no-issue= article-no= start-page=25 end-page=32 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=アメリカ産ダイズ品種‘UA4805’ の多収性に関する解析的研究－日本品種 ‘あきまろ’ との比較－ kn-title=Analytical studies on high-yielding characteristics of US soybean cv. ‘UA4805’ in comparison with Japanese cv. ‘Akimaro’ en-subtitle= kn-subtitle= en-abstract=2020年と2021年に岡山大学農学部附属山陽圏フィールド科学センター（34°41?N, 133°55?E）でダイズの栽培試験を行った．アメリカ品種‘UA4805’ と日本品種‘あきまろ’ の2 品種を供試し，栽植密度を12.5 株 m-2（疎植，80 × 10 cm）と25 株m-2（密植，80 × 5 cm）の2 段階として，2020年5 月25日（早期）， 6 月29日（普通期）， 8 月3 日（晩期）に播種した．2021年は畦幅80 cm（広畦）と30 cm（狭畦），栽植密度12.5株m-2と25株m-2の2 段階で栽培した．子実収量は，2020年と2021年ともに‘あきまろ’ よりも‘UA4805’ の方が高かった．播種時期が遅いほど，粒/茎比が高くなった．両品種ともに疎植区に比べ密植区で乾物重が大きくなった．‘あきまろ’ は‘UA4805’ よりも乾物重は大きかったが，子実収量は低かった．一方，?UA4805? は乾物重が小さかったが，節数，莢数，子実数が多く，子実収量が高かった．‘あきまろ’ は特に密植区において，倒伏程度が大きかった．粒/茎比は，いずれの試験区においても? あきまろ’に比べ‘UA4805’ が著しく高かった．結莢率は‘UA4805’ が‘あきまろ’ より2 倍近く高かった．‘UA4805’ の子実収量が‘あきまろ’ に比べて高かったのは，結莢率，粒/茎比が高く，倒伏程度が小さかったことによるが，乾物生産は‘あきまろ’ の方が大きかった．晩期栽培の場合，子実収量を向上させるためには栽植密度を高くすることが推奨された．ダイズの子実収量を向上させるには，狭畦栽培が効果的であった． kn-abstract=Field experiments were conducted in 2020 and 2021 at the Field Science Center of Okayama Univ. (34°41’ N, 133°55’ E). Two Soybean cultivars ‘UA4805’ and ‘Akimaro’ were sown with two planting densities, 12.5plants m?2 (sparse, 80×10cm) and 25plants m?2 (dense, 80×5cm)on May 25 (early), June 29 (normal), and Aug. 3 (late) in 2020, and 80 and 30cm row-width, and 12.5 and 25 plant m?2 in 2021 on June 23. Seed yield was higher in ‘UA4805’ than in ‘Akimaro’ in 2020 and 2021. The later the sowing time, the higher the seeds/stem ratio. Both cultivars showed higher dry matter in dense planting. Dry matter was higher in ‘Akimaro’, while seed yield was lower than ‘UA4805’. In contrast, ‘UA4805’ showed lower dry matter with higher seed yield. The numbers of nodes, pods, and seeds were higher in ‘UA4805’ resulting in the higher seed yield. Lodging score is larger in ‘Akimaro’ especially in dense planting. The seeds/stem ratio is much higher in ‘UA4805’ than ‘Akimaro’ across 2 densities, 3 sowing times and 2 row width. Pods setting ratio was nearly two times higher in ‘UA4805’ compared to ‘Akimaro’. The greater seed yield of ‘UA4805’ compared to ‘Akimaro’ was due to the higher pod setting ratio, seeds/stem ratio, and lower lodging score, nevertheless the dry matter was larger in ‘Akimaro’. If late sowing is applied, higher planting density is recommended for better seed yield. Narrow row is an effective way to improve seed yield in soybean. en-copyright= kn-copyright= en-aut-name=MaroufSultanzada Mohammad en-aut-sei=Marouf en-aut-mei=Sultanzada Mohammad kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HasegawaYu en-aut-sei=Hasegawa en-aut-mei=Yu kn-aut-name=長谷川湧 kn-aut-sei=長谷川 kn-aut-mei=湧 aut-affil-num=2 ORCID= en-aut-name=ManabeRyuta en-aut-sei=Manabe en-aut-mei=Ryuta kn-aut-name=眞鍋竜太 kn-aut-sei=眞鍋 kn-aut-mei=竜太 aut-affil-num=3 ORCID= en-aut-name=SaitohKuniyuki en-aut-sei=Saitoh en-aut-mei=Kuniyuki kn-aut-name=齊藤邦行 kn-aut-sei=齊藤 kn-aut-mei=邦行 aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science kn-affil=岡山大学大学院環境生命科学研究科 affil-num=2 en-affil=School of Agriculture kn-affil=岡山大学農学部 affil-num=3 en-affil=School of Agriculture kn-affil=岡山大学農学部 affil-num=4 en-affil=Graduate School of Environmental and Life Science kn-affil=岡山大学大学院環境生命科学研究科 en-keyword=Narrow row kn-keyword=Narrow row en-keyword=Planting density kn-keyword=Planting density en-keyword=Podding rate kn-keyword=Podding rate en-keyword=Seeds/stem ratio kn-keyword=Seeds/stem ratio en-keyword=Seed yield kn-keyword=Seed yield en-keyword=Sowing time kn-keyword=Sowing time en-keyword=Soybean kn-keyword=Soybean END start-ver=1.4 cd-journal=joma no-vol=117 cd-vols= no-issue=1 article-no= start-page=181 end-page=188 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinical Features of Patients With Second Primary Lung Cancer After Head and Neck Cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background In survivors of head and neck cancer (HNC), second primary lung cancer (SPLC) often develop as a result of a common risk factor, that is, smoking. A multicenter experience was reviewed to evaluate how the history of a diagnosis of HNC affects the outcomes of patients undergoing pulmonary resection for SPLC.
Methods A multicenter retrospective analysis of patients hospitalized between January 2012 and December 2018 was performed. From a cohort of 4521 patients undergoing therapeutic pulmonary resection for primary non-small cell lung cancer, 100 patients with a previous history of HNC (HNC group) were identified. These patients were compared with a control group consisting of 200 patients without an HNC history from the same cohort pair-matched with operating facility, age, sex, and pathologic stage of lung cancer.
Results At the time of surgery for SPLC, the HNC group showed malnutrition with a lower prognostic nutritional index compared with the control group (P < .001). The HNC group was determined to have postoperative complications more frequently (P = .02). The 5-year overall survival rates in the HNC and control groups were 59.0% and 83.2%, respectively (P < .001). Statistically, HNC history, lower prognostic nutritional index, squamous cell lung cancer, and TNM stage were identified to be independently associated with poor survival.
Conclusions Patients with SPLC after primary HNC often present with malnutrition and are predisposed to postoperative complications and poor survival after pulmonary resection. en-copyright=

resuscitation on return of spontaneous circulation in out-of-hospital cardiac arrest patients: A retrospective observational study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Gastric inflation caused by excessive ventilation is a common complication of cardiopulmonary resuscitation. Gastric inflation may further compromise ventilation via increases in intrathoracic pressure, leading to decreased venous return and cardiac output, which may impair out-of-hospital cardiac arrest (OHCA) outcomes. The purpose of this study was to measure the gastric volume of OHCA patients using computed tomography (CT) scan images and evaluate the effect of gastric inflation on return of spontaneous circulation (ROSC).
Methods: In this single-center, retrospective, observational study, CT scan was conducted after ROSC or immediately after death. Total gastric volume was measured. Primary outcome was ROSC. Achievement of ROSC was compared in the gastric distention group and the no gastric distention group; gastric distension was defined as total gastric volume in the ?75th percentile. Additionally, factors associated with gastric distention were examined.
Results: A total of 446 cases were enrolled in the study; 120 cases (27%) achieved ROSC. The median gastric volume was 400 ml for all OHCA subjects; 1068 ml in gastric distention group vs. 287 ml in no gastric distention group. There was no difference in ROSC between the groups (27/112 [24.1%] vs. 93/334 [27.8%], p = 0.440). Gastric distention did not have a significant impact, even after adjustments (adjusted odds ratio 0.73, 95% confidence interval [0.42?1.29]). Increased gastric volume was associated with longer emergency medical service activity time.
Conclusions: We observed a median gastric volume of 400 ml in patients after OHCA resuscitation. In our setting, gastric distention did not prevent ROSC. en-copyright= kn-copyright= en-aut-name=NaitoHiromichi en-aut-sei=Naito en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HanafusaHiroaki en-aut-sei=Hanafusa en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HongoTakashi en-aut-sei=Hongo en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YumotoTetsuya en-aut-sei=Yumoto en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=WeissmanAlexandra en-aut-sei=Weissman en-aut-mei=Alexandra kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=RittenbergerJon C. en-aut-sei=Rittenberger en-aut-mei=Jon C. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=GuyetteFrancis X. en-aut-sei=Guyette en-aut-mei=Francis X. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FujishimaMamoru en-aut-sei=Fujishima en-aut-mei=Mamoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MaeyamaHiroki en-aut-sei=Maeyama en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NakaoAstunori en-aut-sei=Nakao en-aut-mei=Astunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Emergency and Critical Care Center, Tsuyama Chuo Hospital kn-affil= affil-num=3 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Emergency Medicine, University of Pittsburgh School of Medicine kn-affil= affil-num=7 en-affil=Department of Emergency Medicine, Guthrie Robert Packer Hospital kn-affil= affil-num=8 en-affil=Department of Emergency Medicine, University of Pittsburgh School of Medicine kn-affil= affil-num=9 en-affil=Department of Radiology, Tsuyama Chuo Hospital kn-affil= affil-num=10 en-affil=Emergency and Critical Care Center, Tsuyama Chuo Hospital kn-affil= affil-num=11 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Heart arrest kn-keyword=Heart arrest en-keyword=Cardiopulmonary resuscitation kn-keyword=Cardiopulmonary resuscitation en-keyword=Airway management kn-keyword=Airway management en-keyword=Ventilation kn-keyword=Ventilation en-keyword=Insufflation kn-keyword=Insufflation en-keyword=Regurgitation kn-keyword=Regurgitation END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=2 article-no= start-page=e12636 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231229 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Trends in childhood obesity in Japan: A nationwide observational study from 2012 to 2021 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The persistent ascension of childhood obesity on a global scale constitutes a significant quandary. The prevalence of childhood obesity in Japan peaked in the early 2000s and has been reported to have declined since then, but recent data and its trend including the novel coronavirus disease 2019 (COVID-19) pandemic era are not available. Moreover, there is a dearth of studies examining the correlation between the trend in childhood obesity and exercise habits over the past decade. This study aims to examine the changes in the prevalence of obesity, physical fitness, and exercise habits over the past 10?years in Japanese children. We investigated the prevalence of childhood obesity in Japan, using the School Health Statistics Survey data from 2012 to 2021. The dataset has a sample size representative of children nationwide and includes variables for obesity, such as height, weight, and age. Data were classified into groups by sex and age (6?8, 9?11, and 12?14?years age). Children weighing 20% or more of the standard body weight are classified as obese. The annual percentage changes and average annual percentage changes were estimated using the joinpoint regression model. We also examined the trends in the physical fitness test score and exercise time. Average annual percentage changes of boys increased, especially in the 6- to 8-year age group (3.4%?4.6%). For girls, average annual percentage changes had increased in 6- to 8-year (2.5%?4.0%) and 9- to 11-year (0.9%?2.2%) age groups. Since the late 2010s, significantly increasing annual percentage changes were observed in 12- to 14-year age boys (6.7%?8.9%) and girls of many age groups (2.6%?8.6%). The physical fitness test score and exercise time showed decreasing trends since the late 2010s. Childhood obesity may have generally risen in Japan, in the last decade. Encouraging healthy eating and physical activity through school policies and curricula is necessary. en-copyright= kn-copyright= en-aut-name=FujiwaraShintaro en-aut-sei=Fujiwara en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HaradaKo en-aut-sei=Harada en-aut-mei=Ko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KoyamaToshihiro en-aut-sei=Koyama en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HasegawaKosei en-aut-sei=Hasegawa en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TsukaharaHirokazu en-aut-sei=Tsukahara en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Pediatrics, NHO Okayama Medical Center kn-affil= affil-num=2 en-affil=Department of Medicine, Icahn School of Medicine at Mount Sinai, Mount Sinai Beth Israel kn-affil= affil-num=3 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Pharmaceutical Biomedicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=childhood obesity kn-keyword=childhood obesity en-keyword=epidemiology kn-keyword=epidemiology en-keyword=joinpoint regression analysis kn-keyword=joinpoint regression analysis en-keyword=paediatrics kn-keyword=paediatrics en-keyword=trend analysis kn-keyword=trend analysis END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=24 article-no= start-page=3619 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231207 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Characteristic Mean Kurtosis Values in Simple Diffusion Kurtosis Imaging of Dentigerous Cysts en-subtitle= kn-subtitle= en-abstract= kn-abstract=We evaluated the usefulness of simple diffusion kurtosis (SD) imaging, which was developed to generate diffusion kurtosis images simultaneously with an apparent diffusion coefficient (ADC) map for 27 cystic disease lesions in the head and neck region. The mean kurtosis (MK) and ADC values were calculated for the cystic space. The MK values were dentigerous cyst (DC): 0.74, odontogenic keratocyst (OKC): 0.86, ranula (R): 0.13, and mucous cyst (M): 0, and the ADC values were DC: 1364 × 10?6 mm2/s, OKC: 925 × 10?6 mm2/s, R: 2718 × 10?6 mm2/s, and M: 2686 × 10?6 mm2/s. The MK values of DC and OKC were significantly higher than those of R and M, whereas their ADC values were significantly lower. One reason for the characteristic signal values in diffusion-weighted images of DC may be related to content components such as fibrous tissue and exudate cells. When imaging cystic disease in the head and neck region using SD imaging, the maximum b-value setting at the time of imaging should be limited to approximately 1200 s/mm2 for accurate MK value calculation. This study is the first to show that the MK values of DC are characteristically higher than those of other cysts. en-copyright= kn-copyright= en-aut-name=FukumuraYuka en-aut-sei=Fukumura

growth of amorphous carbon films on a sapphire surface was investigated using classical molecular dynamics simulation. The kinetic energy of carbon particles was set as 10 eV and ReaxFF potential was used to express the interaction between different kinds of particles. The results of the temperature distribution in both deposition time and deposition space are reported. Simulation results reveal that the grown amorphous carbon film consists of four regions, namely interlayer, low density, stable growth, and surface regions. In the interlayer region, the interlayer between substrate and pure carbon film is formed. In the low density region, a pure carbon film is grown while the film density decreases initially and then increases. In the stable growth region, the film density remains almost constant. The film density decreases rapidly in the surface region. The radial distribution function (RDF) analysis suggests that a structure similar to that of diamond exists in the stable growth region of the film. The lower film density in the low density and surface regions was interpreted to indicate the existence of abundant sp1 chain structures, which is supported by the depth profile of the sp fractions. The present results are in good agreement with previous experimental and simulation results and demonstrate the suitability of the ReaxFF potential in the simulation of amorphous carbon growth on sapphire substrate. Our study provides a good starting point for the simulation study of amorphous carbon films on sapphire substrates. en-copyright= kn-copyright= en-aut-name=YueQiang en-aut-sei=Yue en-aut-mei=Qiang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YokoyaTakayoshi en-aut-sei=Yokoya en-aut-mei=Takayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MuraokaYuji en-aut-sei=Muraoka en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= en-keyword=Amorphous carbon kn-keyword=Amorphous carbon en-keyword=Sapphire substrate kn-keyword=Sapphire substrate en-keyword=Molecular dynamics simulation kn-keyword=Molecular dynamics simulation en-keyword=Empirical potential kn-keyword=Empirical potential END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=100434 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202309 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Comparison of outcomes of out-of-hospital cardiac arrest patients: Emergency calls placed from mobile phones vs. landline phones en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Until recently, calls to the emergency medical service (EMS) from landline phones, which display the caller’s exact location at the dispatch center, had been common. Since the use of mobile phones has become widespread, many emergency calls are now made from mobile phones. Differences in outcomes of out-of-hospital cardiac arrest (OHCA) patients for whom EMS was called from mobile versus landline phones has not yet been fully elucidated.
Methods: We performed a retrospective, population-based analysis in Kobe, Japan to examine whether EMS calls from mobiles improved the prognosis of OHCA patients over EMS calls placed from landlines. The primary outcome was favorable neurological outcome, defined as Cerebral Performance Category (CPC) scores of 1 or 2 at discharge. Secondary outcomes were survival at one-month, survival at discharge, and time durations between call and EMS activities.
Results: Of 4,231 OHCA cases, 2,194 cases (706 landline cases vs. 1,488 mobile cases) were included in this study. The percentages of favorable neurological outcomes were 0.7% (5/706) in the landline group and 3.8% (56/1,488) in the mobile group. Adjusted multivariable logistic regression revealed that favorable neurological outcomes (odds ratio [OR] 3.03, 95% confidence interval [CI] 1.12?8.17, p = 0.03) were better in the mobile group, while one-month survival (OR 1.30, 95% CI 0.80?2.14, p = 0.29) was not significantly different. Bystander CPR was more frequently administered in the mobile group (landlines 61.3% vs. mobiles 68.4%, p < 0.01). Time durations between call to EMS dispatch (184.5 [IQR 157?220 s] vs. 205 [IQR 174?248 s], p < 0.01) and EMS arrival (476.5 [IQR 377?599 s] vs. 491 [IQR 407.5?611.5 s], p < 0.01) were shorter in the landline group.
Conclusions: Although the landline caller location display system seems effective for shorter times between EMS call and EMS arrival, mobile phone use was associated with better neurological outcomes. en-copyright= kn-copyright= en-aut-name=NishimuraTakeshi en-aut-sei=Nishimura en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SugaMasafumi en-aut-sei=Suga en-aut-mei=Masafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HongoTakashi en-aut-sei=Hongo en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YumotoTetsuya en-aut-sei=Yumoto en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakaoAtsunori en-aut-sei=Nakao en-aut-mei=Atsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IshiharaSatoshi en-aut-sei=Ishihara en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NaitoHiromichi en-aut-sei=Naito en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Emergency and Critical Care Medicine, Hyogo Emergency Medical Center kn-affil= affil-num=7 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Cardiac arrest kn-keyword=Cardiac arrest en-keyword=OHCA kn-keyword=OHCA en-keyword=CPR kn-keyword=CPR END start-ver=1.4 cd-journal=joma no-vol=194 cd-vols= no-issue=5 article-no= start-page=e63525 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231229 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Radiological characteristics of skeletal growth in neonates and infants with achondroplasia en-subtitle= kn-subtitle= en-abstract= kn-abstract=Achondroplasia (ACH) is the most common form of skeletal dysplasia characterized by a rhizomelic short stature. Radiological skeletal findings in pediatric and adult patients with ACH include short long bones, a relatively longer fibula compared to the tibia, a narrow lumbar interpedicular distance, and a hypoplastic iliac wing. Nonetheless, the characteristics of skeletal growth during the neonatal and infantile periods have scarcely been explored. Therefore, this retrospective study aimed to analyze the radiological skeletal growth during the neonatal and infantile periods in 41 Japanese patients with genetically confirmed ACH. The length of long bones in the upper and lower limbs and the lumbar interpedicular distances at L1 and L4 were measured. These parameters showed significant positive correlations with age. The upper segment-to-lower segment ratio in the lower limbs resembled the data of healthy controls from previous reports. The L1/L4 and fibula/tibia ratios increased with age, suggesting that some representative skeletal phenotypes of ACH were less distinct during the neonatal and infantile periods. In conclusion, for the first time, this study radiologically characterized skeletal growth during the neonatal and infantile periods of patients with genetically confirmed ACH. en-copyright= kn-copyright= en-aut-name=MiyaharaDaisuke en-aut-sei=Miyahara en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HasegawaKosei en-aut-sei=Hasegawa en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AgoYuko en-aut-sei=Ago en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FutagawaNatsuko en-aut-sei=Futagawa en-aut-mei=Natsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyaharaHiroyuki en-aut-sei=Miyahara en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HiguchiYousuke en-aut-sei=Higuchi en-aut-mei=Yousuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YamadaKazuki en-aut-sei=Yamada en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TetsunagaTomonori en-aut-sei=Tetsunaga en-aut-mei=Tomonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MoriwakeTadashi en-aut-sei=Moriwake en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TanakaHiroyuki en-aut-sei=Tanaka en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TsukaharaHirokazu en-aut-sei=Tsukahara en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Orthopedics, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Orthopedics, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Pediatrics, Iwakuni Clinical Center, National Hospital Organization kn-affil= affil-num=10 en-affil=Department of Pediatrics, Okayama Saiseikai General Hospital kn-affil= affil-num=11 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=bone development kn-keyword=bone development en-keyword=dwarfism kn-keyword=dwarfism en-keyword=growth kn-keyword=growth en-keyword=infant kn-keyword=infant en-keyword=radiography kn-keyword=radiography END start-ver=1.4 cd-journal=joma no-vol=45 cd-vols= no-issue=1 article-no= start-page=35 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Current status and challenges of breast cancer prevention?DNA methylation would lead to groundbreaking progress in breast cancer prevention? en-subtitle= kn-subtitle= en-abstract= kn-abstract=The number of breast cancer patients is increasing worldwide. Furthermore, breast cancer often develops in young people, even those only in their 30s, who play a central role in their families and society. Results from many cohort studies suggest that dietary factors, alcohol consumption, lack of physical activity, obesity, nulliparity, breastfeeding, oral contraceptive use, fertility treatment and hormone replacement therapy are risk factors for breast cancer. However, the effects of lifestyle habits on the human body are complexly intertwined with various factors, and the effects vary from person to person depending on their constitution, etc., so there is no basis for this. Therefore, primary prevention of breast cancer is still not being implemented appropriately and efficiently. Furthermore, advances in genomic technology make it possible to assess the risk of developing breast cancer in some individuals. As a result, the establishment of breast cancer prevention methods has become a health priority for high-risk individuals. Drugs such as tamoxifen and raloxifene are known to prevent the development of breast cancer, based on the results of multiple randomized controlled trials, but there are concerns regarding the side effects of these powerful agents. In addition, several clinical studies have shown that prophylactic mastectomy for women who have BRCA mutations or who are identified as being at high risk reduces the incidence of breast cancer development. However, many issues, such as changes in long-term quality of life after preventive surgery, the optimal timing of surgery and the identification of women who are at high risk but will not develop breast cancer, remain uncertain. In other words, although many researchers have focused on chemoprevention and surgical prevention and clear preventive effects of these strategies have been confirmed, it cannot be said that they are widely accepted. Therefore, the current evidence for chemoprevention and surgical prevention, as well as highlights of several interesting lines of research currently underway, are summarized in this article. en-copyright= kn-copyright= en-aut-name=TsukiokiTakahiro en-aut-sei=Tsukioki en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KhanSeema A. en-aut-sei=Khan en-aut-mei=Seema A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShienTadahiko en-aut-sei=Shien en-aut-mei=Tadahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of General Thoracic Surgery and Breast and Endocrine Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Surgery, Feinberg School of Medicine of Northwestern University kn-affil= affil-num=3 en-affil=Department of General Thoracic Surgery and Breast and Endocrine Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Breast cancer kn-keyword=Breast cancer en-keyword=Prevention kn-keyword=Prevention en-keyword=Risk reduction mastectomy kn-keyword=Risk reduction mastectomy en-keyword=Chemoprevention kn-keyword=Chemoprevention en-keyword=Methylation kn-keyword=Methylation END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=6 article-no= start-page=655 end-page=663 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202312 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Comparison between Cases of Total Hip Arthroplasty Followed by Colonna Capsular Arthroplasty and Lorenz Cast Reduction in Patients with Developmental Dysplasia of the Hip en-subtitle= kn-subtitle= en-abstract= kn-abstract=Most patients with developmental dysplasia of the hip (DDH) now receive closed-reduction treatment within 6 months after birth. The long-term outcomes of patients with late-detection DDH have remained unclear. We reviewed the clinical records of 18 patients who underwent Colonna capsular arthroplasty (n=8) or closed reduction (n=10) for developmental dysplasia of the hip as infants or young children and underwent total hip arthroplasty approximately in midlife. Both the Colonna capsular arthroplasty and closed reduction groups achieved good clinical results after total hip arthroplasty. However, the operating time was longer and the improvements of hip range of motion and clinical score were significantly worse in the Colonna capsular arthroplasty group than in the closed reduction group. en-copyright= kn-copyright= en-aut-name=EndoHirosuke en-aut-sei=Endo en-aut-mei=Hirosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamadaKazuki en-aut-sei=Yamada en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TetsunagaTomonori en-aut-sei=Tetsunaga en-aut-mei=Tomonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NambaYoshifumi en-aut-sei=Namba en-aut-mei=Yoshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SugimotoYoshihisa en-aut-sei=Sugimoto en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MitaniShigeru en-aut-sei=Mitani en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakataEiji en-aut-sei=Nakata en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Bone and Joint Surgery, Kawasaki Medical School kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Bone and Joint Surgery, Kawasaki Medical School kn-affil= affil-num=5 en-affil=Department of Bone and Joint Surgery, Kawasaki Medical School kn-affil= affil-num=6 en-affil=Department of Bone and Joint Surgery, Kawasaki Medical School kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=developmental hip dysplasia kn-keyword=developmental hip dysplasia en-keyword=long-term follow-up kn-keyword=long-term follow-up en-keyword=closed reduction kn-keyword=closed reduction en-keyword=Colonna capsular arthroplasty kn-keyword=Colonna capsular arthroplasty en-keyword=total hip arthroplasty kn-keyword=total hip arthroplasty END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=6 article-no= start-page=635 end-page=645 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202312 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of Nutritional Support Combined with Neuromuscular Electrical Stimulation on Muscle Strength and Thickness: A Randomized Controlled Trial in Healthy Young Adult Males en-subtitle= kn-subtitle= en-abstract= kn-abstract=In the management of post-injury patients with activity limitations, methods to prevent musculoskeletal disorders and hasten recovery are important. This randomized controlled, single-blinded study was a preliminary investigation of the combined effect of nutritional support with neuromuscular electrical stimulation (NMES) on muscle strength and thickness. Healthy young adult males (median age, 21 years) were enrolled; each of their hands was randomly assigned to one of the following four groups: Placebo, Nutrition, NMES, and Nutrition + NMES. All participants received whey protein or placebo (3x/week for 6 weeks) and NMES training (3x/week for 6 weeks) on the abductor digiti minimi (ADM) muscle of either the left or right hand. ADM muscle strength and thickness were analyzed at baseline and at week 7. We analyzed 38 hands (9 Placebo, 10 Nutrition, 9 NMES, 10 Nutrition + NMES). There was significantly greater muscle strengthening in the Nutrition + NMES group compared to the Placebo group or the NMES group, but no significant difference in gain of muscle thickness. The combined intervention may be effective in improving muscle strength. Future clinical trials targeting various muscles after sports-related injuries are warranted. en-copyright= kn-copyright= en-aut-name=IkedaTomohiro en-aut-sei=Ikeda en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkamuraKazunori en-aut-sei=Okamura en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HasegawaMasaki en-aut-sei=Hasegawa en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaSatoshi en-aut-sei=Tanaka en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KanaiShusaku en-aut-sei=Kanai en-aut-mei=Shusaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Rehabilitation Medicine, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Physical Therapy, Faculty of Health and Welfare, Prefectural University of Hiroshima kn-affil= affil-num=3 en-affil=Department of Physical Therapy, Faculty of Health and Welfare, Prefectural University of Hiroshima kn-affil= affil-num=4 en-affil=Department of Physical Therapy, Faculty of Health and Welfare, Prefectural University of Hiroshima kn-affil= affil-num=5 en-affil=Department of Physical Therapy, Faculty of Health and Welfare, Prefectural University of Hiroshima kn-affil= en-keyword=whey protein kn-keyword=whey protein en-keyword=electrical stimulation kn-keyword=electrical stimulation en-keyword=muscle strength kn-keyword=muscle strength en-keyword=healthy volunteers kn-keyword=healthy volunteers END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=6 article-no= start-page=627 end-page=634 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202312 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Abnormal Vaginal Cytology after Total Laparoscopic Hysterectomy in Patients with Cervical Intraepithelial Neoplasia en-subtitle= kn-subtitle= en-abstract= kn-abstract=To explore the incidence of abnormal vaginal cytology after total laparoscopic hysterectomy for the treatment of cervical intraepithelial neoplasia 3, we retrospectively analyzed the medical records of patients treated at NHO Shikoku Cancer Center (Japan) in 2014-2019. The cases of 99 patients who underwent a laparoscopic (n=36) or open (n=63) hysterectomy and postoperative follow-up were examined. Abnormal vaginal cytology was detected in 13.9% (5/36) of the laparoscopic-surgery (LS) group and 14.3% (9/63) of the open-surgery (OS) group. A vaginal biopsy was performed at the physicians’ discretion; one LS patient and six OS patients were diagnosed with vaginal intraepithelial neoplasia. The cumulative incidence of abnormal vaginal cytology at 3 years post-hysterectomy was 21.4% (LS group) and 20.5% (OS group), a nonsignificant difference. A multivariate analysis showed that age > 50 years was the only independent risk factor for abnormal vaginal cytology among the covariates examined including age; body mass index; histories of vaginal delivery, abdominal surgery, and smoking; and surgical approach (hazard ratio 8.11; 95% confidence interval 1.73-37.98; p=0.01). These results suggest that the occurrence of abnormal vaginal cytology after a hysterectomy may not be influenced by the laparoscopic procedure but is associated with older age. en-copyright= kn-copyright= en-aut-name=HibinoYumi en-aut-sei=Hibino en-aut-mei=Yumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Okazawa-SakaiMika en-aut-sei=Okazawa-Sakai en-aut-mei=Mika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YokoyamaTakanori en-aut-sei=Yokoyama en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujimotoEtsuko en-aut-sei=Fujimoto en-aut-mei=Etsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkameShinichi en-aut-sei=Okame en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TeramotoNorihiro en-aut-sei=Teramoto en-aut-mei=Norihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakeharaKazuhiro en-aut-sei=Takehara en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Gynecologic Oncology, NHO Shikoku Cancer Center kn-affil= affil-num=2 en-affil=Department of Gynecologic Oncology, NHO Shikoku Cancer Center kn-affil= affil-num=3 en-affil=Department of Gynecologic Oncology, NHO Shikoku Cancer Center kn-affil= affil-num=4 en-affil=Department of Gynecologic Oncology, NHO Shikoku Cancer Center kn-affil= affil-num=5 en-affil=Department of Gynecologic Oncology, NHO Shikoku Cancer Center kn-affil= affil-num=6 en-affil=Department of Pathology, NHO Shikoku Cancer Center kn-affil= affil-num=7 en-affil=Department of Gynecologic Oncology, NHO Shikoku Cancer Center kn-affil= en-keyword=total laparoscopic hysterectomy kn-keyword=total laparoscopic hysterectomy en-keyword=vaginal intraepithelial neoplasia kn-keyword=vaginal intraepithelial neoplasia en-keyword=cervical intraepithelial neoplasia kn-keyword=cervical intraepithelial neoplasia en-keyword=vaginal cytology kn-keyword=vaginal cytology en-keyword=risk factor kn-keyword=risk factor END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=6 article-no= start-page=595 end-page=605 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202312 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Concomitant Use of Multiple Nephrotoxins including Renal Hypoperfusion Medications Causes Vancomycin-Associated Nephrotoxicity: Combined Retrospective Analyses of Two Real-World Databases en-subtitle= kn-subtitle= en-abstract= kn-abstract=There is a growing concern about the relationship between vancomycin-associated nephrotoxicity (VAN) and concomitant use of nephrotoxins. We examined this relationship by combined retrospective analyses of two real-world databases. Initially, the FDA Adverse Event Reporting System (FAERS) was analyzed for the effects of concomitant use of one or more nephrotoxins on VAN and the types of combinations of nephrotoxins that exacerbate VAN. Next, electronic medical records (EMRs) of patients who received vancomycin (VCM) at Tokushima University Hospital between January 2006 and March 2019 were examined to confirm the FAERS analysis. An elevated reporting odds ratio (ROR) was observed with increases in the number of nephrotoxins administered (VCM + one nephrotoxin, adjusted ROR (95% confidence interval [CI]) 1.67 [1.51-1.85]; VCM + ?2 nephrotoxins, adjusted ROR [95% CI] 1.54 [1.37-1.73]) in FAERS. EMRs analysis showed that the number of nephrotoxins was associated with higher incidences of VAN [odds ratio: 1.99; 95% CI: 1.42-2.78]. Overall, concomitant use of nephrotoxins was associated with an increased incidence of VAN, especially when at least one of those nephrotoxins was a renal hypoperfusion medication (furosemide, non-steroidal anti-inflammatory drugs, and vasopressors). The concomitant use of multiple nephrotoxins, especially including renal hypoperfusion medication, should be avoided to prevent VAN. en-copyright= kn-copyright= en-aut-name=BandoTakashi

kn-title=Impact of changes in skeletal muscle mass and quality during the waiting time on outcomes of lung transplantation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: The association of changes in skeletal muscle mass and quality during the waiting time with outcomes of lung transplantation (LT) remains unclear. We aimed to examine the association of changes in skeletal muscle mass and quality during the waiting time, as well as preoperative skeletal muscle mass and quality, with outcomes of LT.
Methods: This study included individuals who underwent LT from brain-dead donors. Skeletal muscle mass (cm2/m2) and quality (mean Hounsfield units [HU]) of the erector spinae muscle at the 12th thoracic level were evaluated using computed tomography. Preoperative skeletal muscle mass and quality, and their changes during the waiting time were calculated. We evaluated the associations among mechanical ventilation (MV) duration, intensive care unit (ICU) length of stay (LOS), hospital LOS, 6-minute walk distance at discharge, and 5-year survival after LT.
Results: This study included 98 patients. The median waiting time was 594.5 days (interquartile range [IQR], 355.0?913.0). The median changes in skeletal muscle mass and quality were ?4.4% (IQR, ?13.3?3.1) and ?2.9% (IQR, ?16.0?4.1), respectively. Severe low skeletal muscle mass at LT was associated with prolonged ICU LOS (B = 8.46, 95% confidence interval [CI]: .51?16.42) and hospital LOS (B = 36.00, 95% CI: 3.23?68.78). Pronounced decrease in skeletal muscle mass during the waiting time was associated with prolonged MV duration (B = 7.85, 95% CI: .89?14.81) and ICU LOS (B = 7.97, 95% CI: .83?15.10).
Conclusion: Maintaining or increasing skeletal muscle mass during the waiting time would be beneficial to improve the short-term outcomes of LT. en-copyright= kn-copyright= en-aut-name=HagiyamaAkikazu en-aut-sei=Hagiyama en-aut-mei=Akikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SugimotoSeiichiro en-aut-sei=Sugimoto en-aut-mei=Seiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaShin en-aut-sei=Tanaka en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsubaraKei en-aut-sei=Matsubara en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyoshiKentaroh en-aut-sei=Miyoshi en-aut-mei=Kentaroh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KatayamaYoshimi en-aut-sei=Katayama en-aut-mei=Yoshimi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HamadaMasanori en-aut-sei=Hamada en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SendaMasuo en-aut-sei=Senda en-aut-mei=Masuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Division of Physical Medicine and Rehabilitation, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Division of Physical Medicine and Rehabilitation, Okayama University Hospital kn-affil= affil-num=7 en-affil=Division of Physical Medicine and Rehabilitation, Okayama University Hospital kn-affil= affil-num=8 en-affil=Division of Physical Medicine and Rehabilitation, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=computed tomography kn-keyword=computed tomography en-keyword=lung transplantation kn-keyword=lung transplantation en-keyword=prognosis kn-keyword=prognosis en-keyword=skeletal muscle kn-keyword=skeletal muscle en-keyword=waiting time kn-keyword=waiting time END start-ver=1.4 cd-journal=joma no-vol=23 cd-vols= no-issue=1 article-no= start-page=859 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231112 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The effectiveness of simulation-based education combined with peer-assisted learning on clinical performance of first-year medical residents: a case-control study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Simulation-based education and peer-assisted learning (PAL) are both known as useful educational methods. Previous research has reported that combining these two methods are effective for training medical residents in short-term evaluation. This study was aimed to evaluate the middle- to long-term effects of simulation-based education combined with PAL on the performance of medical residents during emergency department duties.
Methods This study was designed as a case-control study and conducted over three years at Okayama University Hospital in Japan. Postgraduate-year-one medical residents were assigned to three groups: a simulation group that received simulation-based education, a lecture group that received traditional lecture-based education, and a control group that received no such prior trainings. Prior training in emergency department duties using PAL was performed as an educational intervention for the simulation and lecture groups during the clinical orientation period. The residents' medical knowledge was assessed by written examinations before and after the orientation. The performance of residents during their emergency department duties was assessed by self-evaluation questionnaires and objective-assessment checklists, following up with the residents for three months after the orientation period and collecting data on their 1st, 2nd, and 3rd emergency department duties. All the datasets collected were statistically analyzed and compared by their mean values among the three groups.
Results A total of 75 residents were included in the comparative study: 27 in the simulation group, 24 in the lecture group, and 24 in the control group. The simulation and lecture groups obtained significantly higher written examination scores than the control group. From the self-evaluation questionnaires, the simulation group reported significantly higher satisfaction in their prior training than the lecture group. No significant differences were found in the emergency department performance of the residents among the three groups. However, when evaluating the improvement rate of performance over time, all three groups showed improvement in the subjective evaluation, and only the simulation and lecture groups showed improvement in the objective evaluation.ConclusionSimulation-based education combined with PAL is effective in improving the knowledge and satisfaction of medical residents, suggesting the possibility of improving work performance during their emergency department duties. en-copyright= kn-copyright= en-aut-name=MurakamiTaku en-aut-sei=Murakami en-aut-mei=Taku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamamotoAkira en-aut-sei=Yamamoto en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ObikaMikako en-aut-sei=Obika en-aut-mei=Mikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MandaiYasuhiro en-aut-sei=Mandai en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyoshiTomoko en-aut-sei=Miyoshi en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KataokaHitomi en-aut-sei=Kataoka en-aut-mei=Hitomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of General Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of General Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Department of General Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Department of Emergency Medicine, The JIKEI University kn-affil= affil-num=6 en-affil=Department of General Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Diversity Enhancement Center, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of General Medicine, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= en-keyword=Medical Education kn-keyword=Medical Education en-keyword=Educational Measurement kn-keyword=Educational Measurement en-keyword=Simulation Training kn-keyword=Simulation Training en-keyword=Peer Group kn-keyword=Peer Group en-keyword=Emergency Medicine kn-keyword=Emergency Medicine en-keyword=Internship and residency kn-keyword=Internship and residency en-keyword=Curriculum kn-keyword=Curriculum en-keyword=Personal satisfaction kn-keyword=Personal satisfaction en-keyword=Case-control studies kn-keyword=Case-control studies END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=2023 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Optimal liver drainage rate for survival in patients with unresectable malignant hilar biliary obstruction using 3D-image volume analyzer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Drainage exceeding 50% of total liver volume is a beneficial prognostic factor in patients with unresectable malignant hilar biliary obstruction (UMHBO). However, it is unclear what threshold percentage of total liver volume drained ('liver drainage rate') significantly improves survival in patients with UMHBO who received systemic chemotherapy.
Objectives: We aimed to assess the optimal liver drainage rate that improves survival in patients with UMHBO receiving chemotherapy using a three-dimensional (3D)-image volume analyzer.
Design: This study was a single-center retrospective cohort study.
Methods: Data from 90 patients with UMHBO who received chemotherapy after endoscopic biliary drainage using metal stents at Okayama University Hospital from January 2003 to December 2020 were reviewed. The liver drainage rate was calculated by dividing the drained liver volume by the total liver volume using a 3D-image volume analyzer. The primary endpoint was overall survival by liver drainage rate. The secondary endpoints were time to recurrent biliary obstruction (TRBO) and prognostic factors.
Results: The median total liver volume was 1172 (range: 673-2032) mL, and the median liver drainage rate was 83% (range: 50-100). Overall survival was 376 (95% CI: 271-450) days, and patients with >80% drainage (n = 67) had significantly longer survival than those with <80% drainage (n = 23) (450 days versus 224 days, p = 0.0033, log-rank test). TRBO was 201 (95% CI: 155-327) days and did not differ significantly by liver drainage rate. Multivariate Cox proportional hazards regression analysis revealed >80% liver drainage [hazard ratio (HR): 0.35, 95% CI: 0.20-0.62, p = 0.0003] and hilar cholangiocarcinoma (HR: 0.30, 95% CI: 0.17-0.50, p < 0.0001) as significant prognostic factors.
Conclusion: In patients with UMHBO scheduled for chemotherapy, >80% drainage is associated with improved survival. Further prospective multicenter studies are needed to verify the results of this study. en-copyright= kn-copyright= en-aut-name=MorimotoKosaku en-aut-sei=Morimoto en-aut-mei=Kosaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumotoKazuyuki en-aut-sei=Matsumoto en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ObataTaisuke en-aut-sei=Obata en-aut-mei=Taisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OdaTakashi en-aut-sei=Oda en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyamotoKazuya en-aut-sei=Miyamoto en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MatsumiAkihiro en-aut-sei=Matsumi en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TerasawaHiroyuki en-aut-sei=Terasawa en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FujiiYuki en-aut-sei=Fujii en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YamazakiTatsuhiro en-aut-sei=Yamazaki en-aut-mei=Tatsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HoriguchiShigeru en-aut-sei=Horiguchi en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TsutsumiKoichiro en-aut-sei=Tsutsumi en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KatoHironari en-aut-sei=Kato en-aut-mei=Hironari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=biliary obstruction kn-keyword=biliary obstruction en-keyword=chemotherapy kn-keyword=chemotherapy en-keyword=CT volumetry kn-keyword=CT volumetry en-keyword=endoscopic biliary drainage kn-keyword=endoscopic biliary drainage en-keyword=self-expandable metal stent kn-keyword=self-expandable metal stent END start-ver=1.4 cd-journal=joma no-vol=64 cd-vols= no-issue=4 article-no= start-page=ezad304 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231012 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Intravenous infusion of cardiac progenitor cells in animal models of single ventricular physiology en-subtitle= kn-subtitle= en-abstract= kn-abstract=OBJECTIVES: The goal of this study was to identify the practical applications of intravenous cell therapy for single-ventricle physiology (SVP) by establishing experimental SVP models.
METHODS: An SVP with a three-stage palliation was constructed in an acute swine model without cardiopulmonary bypass. A modified Blalock?Taussig (MBT) shunt was created using an aortopulmonary shunt with the superior and inferior venae cavae (SVC and IVC, respectively) connected to the left atrium (n?=?10). A bidirectional cavopulmonary shunt (BCPS) was constructed using a graft between the IVC and the left atrium with an SVC cavopulmonary connection (n?=?10). The SVC and the IVC were connected to the pulmonary artery to establish a total cavopulmonary connection (TCPC, n?=?10). The survival times of half of the animal models were studied. The other half and the biventricular sham control (n?=?5) were injected intravenously with cardiosphere-derived cells (CDCs), and the cardiac retention of CDCs was assessed after 2?h.
RESULTS: All SVP models died within 20?h. Perioperative mortality was higher in the BCPS group because of lower oxygen saturation (P? CONCLUSIONS: Without the total right heart exclusion, stage-specific SVP models can be functionally constructed in pigs with stable outcomes. Intravenous CDC injections may be applicable in patients with SVP before TCPC completion, given that the initial lung trafficking is efficiently bypassed and sufficient systemic blood flow is supplied from the single ventricle. en-copyright= kn-copyright= en-aut-name=GotoTakuya en-aut-sei=Goto en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OusakaDaiki en-aut-sei=Ousaka en-aut-mei=Daiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HiraiKenta en-aut-sei=Hirai en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KotaniYasuhiro en-aut-sei=Kotani en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KasaharaShingo en-aut-sei=Kasahara en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences and Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences and Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Cardiovascular Pediatrics, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences and Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences and Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences and Okayama University Hospital kn-affil= en-keyword=animal model kn-keyword=animal model en-keyword=single ventricular physiology kn-keyword=single ventricular physiology en-keyword=cell therapy kn-keyword=cell therapy en-keyword=cardiosphere-derived cell kn-keyword=cardiosphere-derived cell en-keyword=intravenous kn-keyword=intravenous END
