We employed persistent homology (PH) to quantitatively characterize the morphology of dendritic microstructures. By using interpretable machine learning with energy analysis, we established a robust relationship between structural features and Gibbs free energy. Through a detailed analysis of how Gibbs free energy evolves with morphological changes in dendrites, we uncovered specific conditions that influence the branching of dendritic structures. Moreover, energy gradient analysis based on morphological feature provides a deeper understanding of the branching mechanisms and offers a pathway to optimize thin-film growth processes. Integrating topology and free energy enables the optimization of a range of materials from fundamental research to practical applications. en-copyright= kn-copyright= en-aut-name=ToneMisato en-aut-sei=Tone en-aut-mei=Misato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SatoShunsuke en-aut-sei=Sato en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KuniiSotaro en-aut-sei=Kunii en-aut-mei=Sotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ObayashiIppei en-aut-sei=Obayashi en-aut-mei=Ippei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HiraokaYasuaki en-aut-sei=Hiraoka en-aut-mei=Yasuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OgawaYui en-aut-sei=Ogawa en-aut-mei=Yui kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FukidomeHirokazu en-aut-sei=Fukidome en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FoggiattoAlexandre Lira en-aut-sei=Foggiatto en-aut-mei=Alexandre Lira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MitsumataChiharu en-aut-sei=Mitsumata en-aut-mei=Chiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NagaokaRyunosuke en-aut-sei=Nagaoka en-aut-mei=Ryunosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=VaradwajArpita en-aut-sei=Varadwaj en-aut-mei=Arpita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=MatsudaIwao en-aut-sei=Matsuda en-aut-mei=Iwao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=KotsugiMasato en-aut-sei=Kotsugi en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Material Science and Technology, Tokyo University of Science kn-affil= affil-num=2 en-affil=Department of Material Science and Technology, Tokyo University of Science kn-affil= affil-num=3 en-affil=Department of Material Science and Technology, Tokyo University of Science kn-affil= affil-num=4 en-affil=Center for Artificial Intelligence and Mathematical Data Science, Okayama University kn-affil= affil-num=5 en-affil=Kyoto University Institute for Advanced Study, Kyoto University kn-affil= affil-num=6 en-affil=NTT Basic Research Laboratories, NTT Corporation kn-affil= affil-num=7 en-affil=Research Institute of Electrical Communication, Tohoku University kn-affil= affil-num=8 en-affil=Department of Material Science and Technology, Tokyo University of Science kn-affil= affil-num=9 en-affil=Department of Material Science and Technology, Tokyo University of Science kn-affil= affil-num=10 en-affil=Department of Material Science and Technology, Tokyo University of Science kn-affil= affil-num=11 en-affil=Department of Material Science and Technology, Tokyo University of Science kn-affil= affil-num=12 en-affil=Institute for Solid State Physics, The University of Tokyo kn-affil= affil-num=13 en-affil=Department of Material Science and Technology, Tokyo University of Science kn-affil= en-keyword=Persistent homology kn-keyword=Persistent homology en-keyword=free energy analysis kn-keyword=free energy analysis en-keyword=structure-toproperty linkage kn-keyword=structure-toproperty linkage en-keyword=dendrite growth kn-keyword=dendrite growth END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue= article-no= start-page=101145 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202511 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Characteristics of out-of-hospital cardiac arrest due to cerebrovascular disorders: a nationwide, retrospective, observational study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Data on out-of-hospital cardiac arrest (OHCA) due to cerebrovascular disorders is limited. This study aimed to describe the characteristics, outcomes, and annual trends of outcomes for OHCA originating from cerebrovascular disorders.
Methods: This study was a retrospective analysis using an Utstein-style Japanese National Registry. Adult patients with OHCA due to cerebrovascular disorders and transported to the hospital between 2005 and 2021 were included. The primary outcome was a favorable neurological outcome at 30-day. We analyzed factors associated with outcomes using a multivariable logistic regression model, then evaluated annual trends of outcomes for cerebrovascular-induced OHCA.
Results: Among 2,081,023 OHCA patients, 52,969 had cerebrovascular-induced cardiac arrest. Of these, 1903 (3.5 %) achieved a favorable neurological outcome. In the multivariable logistic regression model, male sex (adjusted odds ratio [aOR] 1.41, 95 % confidence interval [CI] 1.20–1.61), initial shockable rhythm (aOR 3.10, 95 % CI 2.18–4.40), witnessed cardiac arrest (aOR 1.92, 95 % CI: 1.57–2.34), and prehospital return of spontaneous circulation (ROSC) (aOR 11.1, 95 % CI: 9.09–13.5) were associated with favorable neurological outcomes. Prehospital adrenaline administration was negatively associated with favorable neurological outcomes (aOR 0.22, 95 % CI: 0.16–0.30). The proportion of patients with favorable neurological outcomes increased over time, rising from 3.14 % in 2005 to 4.12 % in 2021.
Conclusions: Although OHCA due to cerebrovascular disorders is generally associated with poor neurological outcomes, 3.5 % of the patients with cerebrovascular-induced OHCA in this study had favorable neurological outcomes, with a yearly trend improving over decades. Patient characteristics associated with a higher likelihood of a favorable neurological outcome included prehospital ROSC, initial shockable rhythm, and witnessed cardiac arrest. en-copyright= kn-copyright= en-aut-name=UedaYoshiyuki en-aut-sei=Ueda en-aut-mei=Yoshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=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=YumotoTetsuya en-aut-sei=Yumoto en-aut-mei=Tetsuya 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=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 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=9 ORCID= affil-num=1 en-affil=Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Department of Emergency, Critical Care, and Disaster Medicine kn-affil= affil-num=2 en-affil=Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Department of Emergency, Critical Care, and Disaster Medicine kn-affil= affil-num=3 en-affil=Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Department of Emergency, Critical Care, and Disaster Medicine kn-affil= affil-num=4 en-affil=Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Department of Emergency, Critical Care, and Disaster Medicine kn-affil= affil-num=5 en-affil=Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Department of Emergency, Critical Care, and Disaster Medicine kn-affil= affil-num=6 en-affil=Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Department of Emergency, Critical Care, and Disaster Medicine kn-affil= affil-num=7 en-affil=Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Department of Epidemiology kn-affil= affil-num=8 en-affil=Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Department of Emergency, Critical Care, and Disaster Medicine kn-affil= affil-num=9 en-affil=Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Department of Emergency, Critical Care, and Disaster Medicine kn-affil= en-keyword=Cardiac arrest kn-keyword=Cardiac arrest en-keyword=Cardiopulmonary resuscitation kn-keyword=Cardiopulmonary resuscitation en-keyword=Cerebral hemorrhage kn-keyword=Cerebral hemorrhage en-keyword=Stroke kn-keyword=Stroke en-keyword=Subarachnoid hemorrhage kn-keyword=Subarachnoid hemorrhage END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=e21664 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251014 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Biologically-Architected Wear and Damage-Resistant Nanoparticle Coating From the Radular Teeth of Cryptochiton stelleri en-subtitle= kn-subtitle= en-abstract= kn-abstract=Nature utilizes simple building blocks to construct mechanically robust materials that demonstrate superior performance under extreme conditions. These exquisite structures result from the controlled synthesis and hierarchical assembly of nanoscale organic and mineral components that have provided critical evolutionary advantages to ensure survival. One such example is the ultrahard radular teeth found in mollusks, which are used to scrape against rock to feed on algae. Here, it is reported that the leading edges of these teeth consist of a wear-resistant coating that is comprised of densely packed ≈65 nm magnetic nanoparticles integrated within an organic matrix of chitin and protein. These mesocrystalline magnetite-based structures are assembled from smaller, highly aligned nanocrystals with inter/intracrystalline organics introduced during the crystallization process. Nanomechanical testing reveals that this multi-scale, nano-architected coating has a combination of increased hardness and a slight decrease in modulus versus geologic magnetite provides the surface of the chiton tooth with superior abrasion resistance. The mesocrystalline structures fracture at primary domain interfaces, corroborated by computational models, providing significant toughening to the tooth under extreme contact stresses. The design features revealed provide insight for the design and fabrication of next-generation advanced wear- and impact-resistant coatings for tooling, machinery, wind turbines, armor, etc. en-copyright= kn-copyright= en-aut-name=WangTaifeng en-aut-sei=Wang en-aut-mei=Taifeng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ChenYu en-aut-sei=Chen en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SarmientoEzra en-aut-sei=Sarmiento en-aut-mei=Ezra kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HaoTaige en-aut-sei=Hao en-aut-mei=Taige kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ArakakiAtsushi en-aut-sei=Arakaki en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NemotoMichiko en-aut-sei=Nemoto en-aut-mei=Michiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ZavattieriPablo en-aut-sei=Zavattieri en-aut-mei=Pablo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KisailusDavid en-aut-sei=Kisailus en-aut-mei=David kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Materials Science and Engineering, University of California kn-affil= affil-num=2 en-affil=Lyles School of Civil and Construction Engineering, Purdue University kn-affil= affil-num=3 en-affil=Department of Materials Science and Engineering, University of California kn-affil= affil-num=4 en-affil=Materials and Manufacturing Technologies Program, University of California kn-affil= affil-num=5 en-affil=Division of Biotechnology and Life Science, Institute of Engineering, Tokyo University of Agriculture and Technology kn-affil= affil-num=6 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=7 en-affil=Lyles School of Civil and Construction Engineering, Purdue University kn-affil= affil-num=8 en-affil=Department of Materials Science and Engineering, University of California kn-affil= en-keyword=biomineralization kn-keyword=biomineralization en-keyword=coatings kn-keyword=coatings en-keyword=damage tolerance kn-keyword=damage tolerance en-keyword=magnetite kn-keyword=magnetite en-keyword=mesocrystals kn-keyword=mesocrystals END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=8 article-no= start-page=e0328792 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250814 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Risk stratification for the prediction of skeletal-related events in patients with castration-resistant prostate cancer with bone metastases en-subtitle= kn-subtitle= en-abstract= kn-abstract=Skeletal-related events (SREs) are common in patients with bone metastases from castration-resistant prostate cancer (CRPC). Despite advances in prostate cancer treatment, clinically validated predictive models for SREs in CRPC patients with bone metastases remain elusive. This gap in prognostic tools hinders optimal patient management and treatment planning for this high-risk population. This study aimed to develop a prediction model for SRE by investigating potential risk factors and classifying them into different groups. This model can be used to identify patients at high risk of SREs who need close follow-up. Between 2004 and 2013, 68 male patients with bone metastases from CRPC who were treated at our institute were evaluated for survival without SREs and survival without SREs of the spinal cord. The study analyzed clinical data at enrollment to identify risk factors for initial and spinal SREs. Multivariate analysis revealed that a high count of metastatic vertebrae, along with visceral or lymph node metastases, were significant risk factors. Patients were categorized into four subgroups based on the number of vertebral metastases and presence of visceral or lymph node metastases: 1) extensive vertebral and both types of metastases, 2) extensive vertebral without additional metastases, 3) some vertebral with other metastases, 4) some vertebral without additional metastases. The first SRE and spinal SRE occurred significantly sooner in the first subgroup compared to others. Incidence rates at 12 months for the first SRE were 56%, 40%, 27%, and 5%, and for the first spinal SRE were 47%, 40%, 27%, and 0% respectively. Patients with extensive vertebral and additional metastases require vigilant monitoring to mitigate SREs. en-copyright= kn-copyright= en-aut-name=HamadaMasanori en-aut-sei=Hamada en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=NakaharaRyuichi en-aut-sei=Nakahara en-aut-mei=Ryuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SugiharaShinsuke en-aut-sei=Sugihara en-aut-mei=Shinsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatayamaHaruyoshi en-aut-sei=Katayama en-aut-mei=Haruyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ItanoTakuto en-aut-sei=Itano en-aut-mei=Takuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=InoueTomohiro en-aut-sei=Inoue en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakihiraShota en-aut-sei=Takihira en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=AkezakiYoshiteru en-aut-sei=Akezaki en-aut-mei=Yoshiteru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil= affil-num=3 en-affil= kn-affil= affil-num=4 en-affil= kn-affil= affil-num=5 en-affil= kn-affil= affil-num=6 en-affil= kn-affil= affil-num=7 en-affil= kn-affil= affil-num=8 en-affil= kn-affil= affil-num=9 en-affil= kn-affil= affil-num=10 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=40608 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251118 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association between gestational age and child health and neurodevelopment in twins from a nationwide longitudinal survey in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Despite previous research, evidence on the relationship between gestational age and long-term health and neurodevelopmental outcomes among twins remains limited. Using data from the Longitudinal Survey of Babies in the 21st Century, we analyzed 549 twins born in Japan in 2010. The twins were grouped by gestational age: <32 weeks (very preterm), 32–36 weeks (moderately and late preterm), and 37–38 weeks (early term). The health status was evaluated by hospitalization between 0.5 and 5.5 years, and behavioral development was assessed using questionnaires at 2.5 and 5.5 years. Binomial log-linear regression with generalized estimating equations accounted for within-pair correlations and adjusted for child and parental variables. Moderately and late preterm children showed a higher risk of all-cause hospitalization during infancy than early-term children (adjusted risk ratio, 1.7; 95% CI, 1.0–2.6). Very preterm children showed a higher point estimate of the risk ratio, but a wide CI (risk ratio, 2.3; 95% CI, 0.8–6.8). Behavioral delays were more common in preterm groups at 2.5 years but not at 5.5 years. Preterm twins have a higher risk of hospitalization during infancy and developmental delay at 2.5 years than early-term twins. These risks show an increasing trend as gestational age decreases. en-copyright= kn-copyright= en-aut-name=TamaiKei en-aut-sei=Tamai en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=TakeuchiAkihito en-aut-sei=Takeuchi en-aut-mei=Akihito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakamuraMakoto en-aut-sei=Nakamura en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KageyamaMisao en-aut-sei=Kageyama en-aut-mei=Misao 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, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Division of Neonatology, NHO Okayama Medical Center kn-affil= affil-num=4 en-affil=Division of Neonatology, NHO Okayama Medical Center kn-affil= affil-num=5 en-affil=Division of Neonatology, NHO Okayama Medical Center kn-affil= affil-num=6 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Behavioral development kn-keyword=Behavioral development en-keyword=Child health kn-keyword=Child health en-keyword=Early term kn-keyword=Early term en-keyword=Gestational age kn-keyword=Gestational age en-keyword=Hospitalization kn-keyword=Hospitalization en-keyword=Multiple births kn-keyword=Multiple births END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=10 article-no= start-page=e95695 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251029 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association of Use of GRADE, Protocol Registration, and Journal Impact Factor With Reporting and Methodological Quality of Systematic Reviews Published in Rehabilitation Journals: A Meta-Epidemiological Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study aimed to identify factors associated with the reporting and methodological quality of systematic reviews (SRs) published in rehabilitation journals. We conducted a meta-epidemiological study as a secondary analysis of a previous study. The study protocol was registered in the Open Science Framework. We analyzed 219 SRs from rehabilitation journals published since 2020. We assessed reporting quality using the Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) 2020 and methodological quality using A MeaSurement Tool to Assess systematic Reviews (AMSTAR) 2. Multiple linear regression and Spearman's correlation were used to identify factors associated with quality, including Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach and the Journal Impact Factor (JIF). Multivariate analysis revealed PRISMA 2020 adherence was significantly associated with use of GRADE (β = 4.33; 95% confidence interval (CI): 3.24-5.42), protocol registration (β = 3.40; 95% CI: 2.32-4.47), and the JIF (2023) (β = 0.69; 95% CI: 0.42-0.95). AMSTAR 2 adherence was also significantly associated with use of GRADE (β = 2.52; 95% CI: 1.88-3.17), protocol registration (β = 2.07; 95% CI: 1.44-2.70), and the JIF (2023) (β = 0.29; 95% CI: 0.14-0.45). Weak positive correlations were observed between the JIF (2023) and both PRISMA 2020 and AMSTAR 2 adherence (ρ = 0.27 and ρ = 0.22, respectively; both P < 0.01). It should be noted that these findings reflect associations and do not imply causality. To enhance the quality of SRs in rehabilitation, researchers should prioritize adherence to PRISMA 2020, particularly the use of GRADE and protocol registration, which this study identified as key associated factors. en-copyright= kn-copyright= en-aut-name=TsugeTakahiro en-aut-sei=Tsuge en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamamotoNorio en-aut-sei=Yamamoto en-aut-mei=Norio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TomitaYosuke en-aut-sei=Tomita en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HagiyamaAkikazu en-aut-sei=Hagiyama en-aut-mei=Akikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShiratsuchiDaijo en-aut-sei=Shiratsuchi en-aut-mei=Daijo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OkamuraMasatsugu en-aut-sei=Okamura en-aut-mei=Masatsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KanekoTakao en-aut-sei=Kaneko en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SuzukiKosuke en-aut-sei=Suzuki en-aut-mei=Kosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakashimaYuki en-aut-sei=Nakashima en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TaitoShunsuke en-aut-sei=Taito en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=11 ORCID= affil-num=1 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Systematic Reviewers, Scientific Research WorkS Peer Support Group (SRWS-PSG) kn-affil= affil-num=3 en-affil=Physical Therapy, Faculty of Health Care, Takasaki University of Health and Welfare kn-affil= affil-num=4 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Physical Therapy, School of Health Sciences, Faculty of Medicine, Kagoshima University kn-affil= affil-num=6 en-affil=Systematic Reviewers, Scientific Research WorkS Peer Support Group (SRWS-PSG) kn-affil= affil-num=7 en-affil=Rehabilitation, Yamagata Prefectural Central Hospital kn-affil= affil-num=8 en-affil=Rehabilitation, Yamagata Saisei Hospital kn-affil= affil-num=9 en-affil=Systematic Reviewers, Scientific Research WorkS Peer Support Group (SRWS-PSG) kn-affil= affil-num=10 en-affil=Systematic Reviewers, Scientific Research WorkS Peer Support Group (SRWS-PSG) kn-affil= affil-num=11 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=citation kn-keyword=citation en-keyword=grade kn-keyword=grade en-keyword=journal impact factor kn-keyword=journal impact factor en-keyword=methodological and reporting quality kn-keyword=methodological and reporting quality en-keyword=prisma kn-keyword=prisma END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=e00463-25 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251128 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Analysis of the drug target of the anti-tuberculosis compound OCT313: phosphotransacetylase is a potential drug target for anti-mycobacterial agents en-subtitle= kn-subtitle= en-abstract= kn-abstract=Tuberculosis (TB) is one of the most common infectious diseases caused by bacteria worldwide. The increasing prevalence of multidrug-resistant TB (MDR-TB) and latent TB infection (LTBI) has intensified the global TB burden. Therefore, the development of new drugs for MDR-TB and LTBI is urgently required. We have reported that the derivative of dithiocarbamate sugar derivative, 2-acetamido-2-deoxy-β-D-glucopyranosyl N,N-dimethyldithiocarbamate (OCT313), exhibits anti-mycobacterial activity against MDR-MTB. Here, we identified the target of OCT313. In experimentally generated OCT313-resistant bacteria, adenine at position 1,092 in the metabolic enzyme phosphotransacetylase (PTA) gene was replaced with cytosine. This mutation is a nonsynonymous mutation that converts methionine to leucine at position 365 in the PTA protein. OCT313 inhibited the enzymatic activity of recombinant wild-type PTA, but not of the mutant PTA (M365L). PTA is an enzyme that produces acetyl-coenzyme A (acetyl-CoA) from acetyl phosphate and CoA and is involved in metabolic pathways; therefore, it was expected to also be active against dormant Mycobacterium tuberculosis bacilli. OCT313 exhibits antibacterial activity in the Wayne model of dormancy using Mycobacterium bovis BCG, and overexpression of PTA in OCT313-resistant bacilli restored sensitivity to OCT313. Collectively, the target of OCT313 is PTA, and OCT313 is a promising antimicrobial candidate for MDR-TB and LTBI. 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=HasegawaTomohiro en-aut-sei=Hasegawa en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ItohSaotomo en-aut-sei=Itoh en-aut-mei=Saotomo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MaedaShinji en-aut-sei=Maeda en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WadaTakayuki en-aut-sei=Wada en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HoritaYasuhiro en-aut-sei=Horita en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NishiyamaAkihito en-aut-sei=Nishiyama en-aut-mei=Akihito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MatsumotoSohkichi en-aut-sei=Matsumoto en-aut-mei=Sohkichi 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=KimishimaAoi en-aut-sei=Kimishima en-aut-mei=Aoi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=11 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=12 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=13 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 Hygienic Chemistry, Graduate School of Pharmaceutical Sciences, Nagoya City University kn-affil= affil-num=3 en-affil=Department of Hygienic Chemistry, Graduate School of Pharmaceutical Sciences, Nagoya City University kn-affil= affil-num=4 en-affil=Graduate School of Pharmaceutical Sciences, Hokkaido University of Sciences kn-affil= affil-num=5 en-affil=Department of Microbiology, Graduate School of Human Life and Ecology, Osaka Metropolitan University kn-affil= affil-num=6 en-affil=Department of Clinical Pharmaceutics, Graduate School of Medical Sciences, Nagoya City University kn-affil= affil-num=7 en-affil=Department of Bacteriology, Niigata University School of Medicine kn-affil= affil-num=8 en-affil=Department of Bacteriology, Niigata University School of Medicine kn-affil= affil-num=9 en-affil=Department of Oral Microbiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Laboratory of Applied Microbial Chemistry, Ōmura Satoshi Memorial Institute, Kitasato University kn-affil= affil-num=11 en-affil=Laboratory of Applied Microbial Chemistry, Ōmura Satoshi Memorial Institute, Kitasato University kn-affil= affil-num=12 en-affil=Department of Hygienic Chemistry, Graduate School of Pharmaceutical Sciences, Nagoya City University kn-affil= affil-num=13 en-affil=Department of Hygienic Chemistry, Graduate School of Pharmaceutical Sciences, Nagoya City University kn-affil= en-keyword=phosphotransacetylase kn-keyword=phosphotransacetylase en-keyword=acetyl coenzyme A kn-keyword=acetyl coenzyme A en-keyword=dithiocarbamate kn-keyword=dithiocarbamate en-keyword=N-acetyl glucosamine kn-keyword=N-acetyl glucosamine en-keyword=anti-mycobacterial agents kn-keyword=anti-mycobacterial agents en-keyword=latent tuberculosis infection kn-keyword=latent tuberculosis infection END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=40522 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251118 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Long intervals between repetitive concussions reduce risk of cognitive impairment and limit microglial activation, astrogliosis, and tauopathy in adolescent rats en-subtitle= kn-subtitle= en-abstract= kn-abstract=Although previous studies have demonstrated the effects of concussions do not accumulate as the time interval between injuries increases, little is known about the relationship between this interval and the effects of repetitive concussions. The objective of this study is to explore the relationship between the time interval and changes in behavior and histology following repetitive concussions. Male adolescent rats received concussions by weight drop and were randomly assigned to one of five experimental groups, receiving concussions three times either daily, every other day, once per week, once every 2 weeks, or receiving sham procedures. Only rats that received daily concussions exhibited cognitive impairment, while the other groups did not. No groups showed motor or anxiety-like impairments. Histological analysis revealed accumulation of microglia, as well as astrogliosis, in the prefrontal cortex, corpus callosum, dentate gyrus, and cornu Ammonis 1 region of the hippocampus in rats subjected to daily concussions. Accumulation of phosphorylated tau was also observed in the prefrontal cortex and cornu Ammonis 1. Longer intervals between concussions may reduce the risk of cognitive impairment and limit microglial activation, astrogliosis, and phosphorylated tau accumulation. These findings may help guide decisions on the appropriate timing for return to play in humans. en-copyright= kn-copyright= en-aut-name=HirataYuichi en-aut-sei=Hirata en-aut-mei=Yuichi kn-aut-name=

migration by regulating the organization of F-actin en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: Dynamin, a GTPase that regulates membrane dynamics, has recently been implicated in actin cytoskeletal remodeling. This study aimed to elucidate the role of dynamin in osteoblast migration by examining the effects of dynamin inhibition on the localization and organization of F-actin and dynamin 2 in MC3T3-E1 cells.
Methods: MC3T3-E1 cells were treated with dynamin inhibitors (Dyngo 4a and Dynole 34-2), and cell migration was assessed using a wound-healing assay. Fluorescent staining was performed to analyze the intracellular localization of F-actin and dynamin 2.
Results: Dynamin inhibition significantly reduced the migration of MC3T3-E1 cells. Fluorescence analysis revealed a marked decrease in the accumulation and colocalization of F-actin and dynamin 2 at the protrusion edge. Additionally, dynamin inhibition suppressed the formation of lamellipodia and stress fibers while promoting the appearance of abnormal F-actin clusters in the cytoplasm.
Conclusions: These findings suggest that dynamin plays an essential role in osteoblast migration by regulating actin cytoskeletal remodeling, particularly through the formation of lamellipodia and stress fibers. en-copyright= kn-copyright= en-aut-name=MoriyaTakumi en-aut-sei=Moriya en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SurongA. en-aut-sei=Surong en-aut-mei=A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TatsumiNanami en-aut-sei=Tatsumi en-aut-mei=Nanami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamadaHiroshi en-aut-sei=Yamada en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakemotoFumiko en-aut-sei=Takemoto en-aut-mei=Fumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KamiokaHiroshi en-aut-sei=Kamioka en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkamuraHirohiko en-aut-sei=Okamura en-aut-mei=Hirohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IkegameMika en-aut-sei=Ikegame en-aut-mei=Mika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Oral Morphology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Neuroscience, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Neuroscience, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Neuroscience, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Orthodontics, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Orthodontics, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Oral Morphology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Oral Morphology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Dynamin kn-keyword=Dynamin en-keyword=Cell migration kn-keyword=Cell migration en-keyword=Osteoblasts kn-keyword=Osteoblasts en-keyword=F-actin kn-keyword=F-actin END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=1 article-no= start-page=219 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251121 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Does perioperative discontinuation of anti-rheumatic drugs increase postoperative complications in orthopedic surgery for rheumatoid arthritis? en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective This study aimed to investigate whether discontinuation of biological or targeted synthetic antirheumatic disease-modifying drugs (bDMARDs or tsDMARDs) influences the incidence of postoperative complications in patients with rheumatoid arthritis (RA) undergoing orthopedic surgery.
Methods A retrospective multicenter cohort study including patients receiving bDMARDs or tsDMARDs who underwent orthopedic surgery was conducted. Data collected encompassed the duration of drug discontinuation and postoperative adverse events, such as delayed wound healing, surgical site infection (SSI), disease flare-ups, and mortality. The association between drug discontinuation and these outcomes was analyzed. Multivariate analyses were conducted to identify potential risk factors for these events.
Results A total of 2,060 cases were initially enrolled. After applying inclusion and exclusion criteria, data from 1,953 patients were analyzed. No significant differences were observed between the groups regarding delayed wound healing, SSI, or mortality. However, the incidence of disease flare-ups was substantially higher in the drug discontinuation group and in the interleukin (IL)-6 inhibitor group. Multivariate analysis identified that tumor necrosis factor α and IL-6 inhibitor use was associated with a higher risk of delayed wound healing relative to T-cell function modifiers.
Conclusion In orthopedic surgery for patients with RA, maintaining the standard or the half of administration interval of bDMARD appears safe in the preoperative period. However, the drug discontinuation may increase the risk of postoperative flare-ups, particularly with IL-6 inhibitors. In addition, T-cell function modifiers may be associated with a lower risk of delayed wound healing, suggesting their safety profile in this context. en-copyright= kn-copyright= en-aut-name=ItoHiromu

Expression in CD44-Positive Stem Cells for Osteoarthritis Progression en-subtitle= kn-subtitle= en-abstract= kn-abstract=Osteoarthritis (OA) is a degenerative joint disease characterized by progressive cartilage breakdown, synovial inflammation, and subchondral bone remodeling. Previous studies have shown that cellular communication network factor 3 (CCN3) expression increases with age in cartilage, and its overexpression promotes OA-like changes by inducing senescence-associated secretory phenotypes. This study aimed to investigate the effect of Ccn3 knockout (KO) on OA development using a murine OA model. Destabilization of the medial meniscus (DMM) surgery was performed in wild-type (WT) and Ccn3-KO mice. Histological scoring and staining were used to assess cartilage degeneration and proteoglycan loss. Gene and protein expressions of catabolic enzyme (Mmp9), hypertrophic chondrocyte marker (Col10a1), senescence marker, and cyclin-dependent kinase inhibitor 1A (Cdkn1a) were evaluated. Single-cell RNA sequencing (scRNA-seq) data from WT and Sox9-deficient cartilage were reanalyzed to identify Ccn3+ progenitor populations. Immunofluorescence staining assessed CD44 and Ki67 expression in articular cartilage. The effects of Ccn3 knockdown on IL-1β-induced Mmp13 and Adamts5 expression in chondrocytes were examined in vitro. Ccn3 KO mice exhibited reduced cartilage degradation and catabolic gene expression compared with WT mice post-DMM. scRNA-seq revealed enriched Ccn3-Cd44 double-positive cells in osteoblast progenitor, synovial mesenchymal stem cell, and mesenchymal stem cell clusters. Immunofluorescence showed increased CCN3+/CD44+ cells in femoral and tibial cartilage and meniscus. Ki67+ cells were significantly increased in DMM-treated Ccn3 KO cartilage, mostly CD44+. In vitro Ccn3 knockdown attenuated IL-1β-induced Mmp13 and Adamts5 expressions in chondrocytes. Ccn3 contributes to OA pathogenesis by promoting matrix degradation, inducing hypertrophic changes, and restricting progenitor cell proliferation, highlighting Ccn3 as a potential therapeutic target for OA. en-copyright= kn-copyright= en-aut-name=HabumugishaJanvier en-aut-sei=Habumugisha en-aut-mei=Janvier kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkudaRyuichiro en-aut-sei=Okuda en-aut-mei=Ryuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HiroseKazuki en-aut-sei=Hirose en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KuwaharaMiho en-aut-sei=Kuwahara en-aut-mei=Miho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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=6 ORCID= en-aut-name=KamiokaHiroshi en-aut-sei=Kamioka en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KubotaSatoshi en-aut-sei=Kubota en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HattoriTakako en-aut-sei=Hattori en-aut-mei=Takako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Biochemistry and Molecular Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Biochemistry and Molecular Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Biochemistry and Molecular Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Biochemistry and Molecular Dentistry, 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 Oral Rehabilitation and Regenerative Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Orthodontics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Biochemistry and Molecular Dentistry, 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=articular kn-keyword=articular en-keyword=cartilage kn-keyword=cartilage en-keyword=mesenchymal stem cells kn-keyword=mesenchymal stem cells en-keyword=nephroblastoma overexpressed protein kn-keyword=nephroblastoma overexpressed protein en-keyword=osteoarthritis kn-keyword=osteoarthritis 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=20251107 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Is Pain Intensity Related to Psychosocial Factors in Chronic Non‐Nociceptive Orofacial Pain Patients? en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: In order to understand the psychological aspects of chronic pain, it is important to consider the relationships between pain and psychosocial factors in patients with chronic pain. While psychosocial factors are known to affect pain intensity in temporomandibular disorders, few studies have evaluated them in patients with other types of chronic orofacial pain.
Objective: The purpose of the present study was to evaluate the relationships between pain intensity and patient characteristics, diagnostic categories and psychosocial factors in chronic non-nociceptive orofacial pain patients.
Methods: In a retrospective, cross-sectional study, we collected information from the medical records of 123 patients with chronic non-nociceptive orofacial pain. Pain intensity was measured using the Brief Pain Inventory (BPI) total score. Analysis of the correlations among the variables revealed several strong correlations. Principal component analysis identified two components: the psychological distress and self-efficacy/quality of life (QOL) components. Multiple linear regression analyses of the overall study population and each ICOP pain category were also performed.
Results: In the overall sample, higher BPI scores were significantly associated with a greater psychological distress component and lower self-efficacy/QOL component. The pain category was not a significant predictor of the BPI score. In the subgroup analyses, both components were significant predictors of the BPI score in myofascial orofacial pain; whereas, only the self-efficacy/QOL component was in idiopathic orofacial pain.
Conclusion: The results indicated that pain intensity in chronic non-nociceptive orofacial pain is related to the self-efficacy/QOL psychosocial factor component. These findings suggest that assessing psychosocial factors may be clinically important for the diagnosis and treatment of chronic orofacial pain. en-copyright= kn-copyright= en-aut-name=KawaseAkiko en-aut-sei=Kawase en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HiguchiHitoshi en-aut-sei=Higuchi en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HashimotoFumika en-aut-sei=Hashimoto en-aut-mei=Fumika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyakeSaki en-aut-sei=Miyake en-aut-mei=Saki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishiokaYukiko en-aut-sei=Nishioka en-aut-mei=Yukiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=InoueMidori en-aut-sei=Inoue en-aut-mei=Midori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=UjitaHitomi en-aut-sei=Ujita en-aut-mei=Hitomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KawauchiAki en-aut-sei=Kawauchi en-aut-mei=Aki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MaedaShigeru en-aut-sei=Maeda en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MiyawakiTakuya en-aut-sei=Miyawaki en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Dental Anesthesiology and Special Care Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Dental Anesthesiology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Dental Anesthesiology and Special Care Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Dental Anesthesiology and Special Care Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Dental Anesthesiology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Dental Anesthesiology, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Dental Anesthesiology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Dental Anesthesiology, Graduate School of Medical and Dental Sciences, Institute of Science Tokyo kn-affil= affil-num=9 en-affil=Department of Dental Anesthesiology, Graduate School of Medical and Dental Sciences, Institute of Science Tokyo kn-affil= affil-num=10 en-affil=Department of Dental Anesthesiology and Special Care Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=chronic pain kn-keyword=chronic pain en-keyword=International Classification of Orofacial Pain kn-keyword=International Classification of Orofacial Pain en-keyword=orofacial pain kn-keyword=orofacial pain en-keyword=psychological distress component kn-keyword=psychological distress component en-keyword=psychosocial factors kn-keyword=psychosocial factors en-keyword=self-efficacy/ QOL component kn-keyword=self-efficacy/ QOL component END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=1 article-no= start-page=166 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251015 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=PEGylation of liposome-encapsulated midazolam does not improve the bioavailability of midazolam when administered orally en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Liposomes are closed vesicles made of the same phospholipid bilayer as biological membranes and are capable of containing drugs, and so they have been investigated as useful drug carriers for drug delivery. We previously developed liposome-encapsulated midazolam (LE-midazolam) for oral administration, but midazolam is metabolized in the liver, and for clinical use the encapsulation of the liposomes needed to be improved to increase the bioavailability of midazolam. The surfaces of pharmaceutical liposomes are generally coated with polyethylene glycol (PEGylation) because it prevents their capture by phagocytes and helps them to avoid the reticuloendothelial system. Therefore, we considered that PEGylation could reduce the metabolism of orally administered encapsulated midazolam in the liver.
Methods Midazolam solution, LE-midazolam solution, and PEGylated liposome-encapsulated midazolam (PEG-LE-midazolam) solution were prepared, and the characteristics of the liposomes in these solutions were evaluated. Furthermore, these solutions were orally administered to rabbits, and the resultant plasma midazolam concentrations were measured. The effects of the PEGylation of LE-midazolam on the plasma concentration and bioavailability of orally administered midazolam were also evaluated.
Results The PEG-LE-midazolam solution contained a higher percentage of larger liposomes than the LE-midazolam solution. The area under the concentration-time curve (AUC) of the LE-midazolam solution was significantly higher than that of the midazolam solution, but there was no difference between the AUC values of the PEG-LE-midazolam and midazolam solutions.
Conclusions These findings suggest that liposome encapsulation may reduce the first-pass effect following oral administration, but PEGylation is not expected to improve the bioavailability of orally administered midazolam. en-copyright= kn-copyright= en-aut-name=NishiokaYukiko en-aut-sei=Nishioka en-aut-mei=Yukiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LuYanyin en-aut-sei=Lu en-aut-mei=Yanyin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HiguchiHitoshi en-aut-sei=Higuchi en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyakeSaki en-aut-sei=Miyake en-aut-mei=Saki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujimotoMaki en-aut-sei=Fujimoto en-aut-mei=Maki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=Hamaoka-InoueMidori en-aut-sei=Hamaoka-Inoue en-aut-mei=Midori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TanimuraHiroshi en-aut-sei=Tanimura en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UjitaHitomi en-aut-sei=Ujita en-aut-mei=Hitomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MaedaShigeru en-aut-sei=Maeda en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MiyawakiTakuya en-aut-sei=Miyawaki en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Dental Anesthesiology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Dental Anesthesiology and Special Care Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Dental Anesthesiology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Dental Anesthesiology and Special Care Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Dental Anesthesiology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Dental Anesthesiology and Special Care Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Dental Anesthesiology and Special Care Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Dental Anesthesiology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Dental Anesthesiology and Special Care Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Dental Anesthesiology and Special Care Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=PEGylation kn-keyword=PEGylation en-keyword=Liposome kn-keyword=Liposome en-keyword=Midazolam kn-keyword=Midazolam en-keyword=Oral administration kn-keyword=Oral administration en-keyword=Bioavailability kn-keyword=Bioavailability END start-ver=1.4 cd-journal=joma no-vol=68 cd-vols= no-issue=1 article-no= start-page=100718 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202602 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluation of Mycobacterium-derived plasmids for application in oral Actinomyces species en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: Genetic manipulation tools are essential for elucidating the pathogenic mechanisms of microorganisms. Several species of Actinomyces, including A. israelii, are present in the oral cavity and they are the causative agents of actinomycosis. However, efficient gene-editing tools for these species have not yet been developed. In this study, the aim was to evaluate the introduction of foreign genes into Actinomyces using plasmids derived from Mycobacterium, which belong to the same class as Actinomycetes.
Methods: A truncated derivative of pYT923, pYT923S, which contains the replication origin of the M. scrofulaceum plasmid pMSC262 was constructed and introduced into A. israelii by electrotransformation.
Results: pYT923S was successfully introduced into A. israelii. The transformation efficiency of A. israelii was approximately 7–66 CFU/μg of DNA, and all transformed colonies harbored pYT923S. The plasmid recovered from A. israelii replicated in Escherichia coli.
Conclusions: pYT923S was introduced into and maintained within A. israelii. Therefore, the pYT923S vector represents a useful genetic tool for Actinomyces and it is expected to facilitate future studies on the biology and pathogenicity of Actinomyces. en-copyright= kn-copyright= en-aut-name=OharaSakiko en-aut-sei=Ohara en-aut-mei=Sakiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShengYijuan en-aut-sei=Sheng en-aut-mei=Yijuan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishiyaYuki en-aut-sei=Nishiya en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TosaIkue en-aut-sei=Tosa en-aut-mei=Ikue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakebeKatsuki en-aut-sei=Takebe en-aut-mei=Katsuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ArimuraYuki en-aut-sei=Arimura en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MeseHiroshi en-aut-sei=Mese en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OharaNaoko en-aut-sei=Ohara en-aut-mei=Naoko 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= affil-num=1 en-affil=Department of Oral Microbiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Oral Microbiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Oral Microbiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Oral Microbiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Dental Pharmacology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Oral and Maxillofacial Reconstructive Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Dentistry and Oral Surgery, Fukuyama City Hospital kn-affil= affil-num=8 en-affil=Department of Operative Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Oral Microbiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Actinomyces kn-keyword=Actinomyces en-keyword=Plasmid kn-keyword=Plasmid en-keyword=Shuttle vector kn-keyword=Shuttle vector en-keyword=Transformation kn-keyword=Transformation END start-ver=1.4 cd-journal=joma no-vol=60 cd-vols= no-issue=5 article-no= start-page=573 end-page=582 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250214 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Diagnostic accuracy and cut-off values of serum leucine-rich alpha-2 glycoprotein for Crohn’s disease activity in the small bowel en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Small bowel (SB) lesions in Crohn’s disease (CD) are often asymptomatic despite being highly active. Fecal calprotectin (FC) is the most widely used biomarker of CD activity, but its drawbacks include a large intra-individual sample variability and the burden of collecting stool samples. Meanwhile, serum leucine-rich alpha-2 glycoprotein (LRG) has recently attracted attention as a biomarker that can address the limitations of FC. This study determined the diagnostic accuracy of LRG and its cut-off values for diagnosing CD activity in SB.
Methods This was a retrospective, multi-center study of CD patients undergoing retrograde balloon-assisted endoscopy. For ileal- and ileocolonic-type patients with a colon SES-CD score of 0, we estimated the receiver operating characteristic curve of LRG and determined the cut-off value to achieve a target sensitivity level of 80%.
Results Among 285 patients with SB lesions, LRG had an area under the curve (AUC) of 0.72 (95% CI 0.67–0.78) with a sensitivity of 80.2% and specificity of 47.2% for a cut-off value of 10.5 when diagnosing endoscopic remission (modified SES-CD ≤ 3), while it had an AUC of 0.72 (95% CI 0.65–0.78) with a sensitivity of 81.2% and specificity of 46.2% for a cut-off value of 10.1 when diagnosing complete ulcer healing (modified SES-CD ≤ 1).
Conclusion LRG was effective for diagnosing CD activity in SB, specifically with cut-off values of 10.5 and 10.1 for endoscopic remission and complete ulcer healing, respectively. A future prospective validation study will assess its clinical utility. en-copyright= kn-copyright= en-aut-name=OkitaMuneyori en-aut-sei=Okita en-aut-mei=Muneyori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakenakaKento en-aut-sei=Takenaka en-aut-mei=Kento kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HiraiFumihito en-aut-sei=Hirai en-aut-mei=Fumihito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AshizukaShinya en-aut-sei=Ashizuka en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IijimaHideki en-aut-sei=Iijima en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=BambaShigeki en-aut-sei=Bamba en-aut-mei=Shigeki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FujiiToshimitsu en-aut-sei=Fujii en-aut-mei=Toshimitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=WatanabeKenji en-aut-sei=Watanabe en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ShimodairaYosuke en-aut-sei=Shimodaira en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ShigaHisashi en-aut-sei=Shiga en-aut-mei=Hisashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=11 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=12 ORCID= en-aut-name=YamamuraTakeshi en-aut-sei=Yamamura en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=EmotoRyo en-aut-sei=Emoto en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=MatsuiShigeyuki en-aut-sei=Matsui en-aut-mei=Shigeyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil=Department of Biostatistics, Nagoya University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Institute of Science Tokyo kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Medicine, Fukuoka University Faculty of Medicine kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Medicine, Fukuoka University Faculty of Medicine kn-affil= affil-num=5 en-affil=Osaka International Medical & Science Center, Osaka Keisatsu Hospital kn-affil= affil-num=6 en-affil=Department of Fundamental Nursing, Shiga University of Medical Science kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Institute of Science Tokyo kn-affil= affil-num=8 en-affil=Department of Internal Medicine for Inflammatory Bowel Disease, Toyama University kn-affil= affil-num=9 en-affil=Department of Gastroenterology and Neurology, Akita University Graduate School of Medicine kn-affil= affil-num=10 en-affil=Division of Gastroenterology, Tohoku University Graduate School of Medicine kn-affil= affil-num=11 en-affil=Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=12 en-affil=Research Center for Intestinal Health Science, Okayama University kn-affil= affil-num=13 en-affil=Department of Gastroenterology and Hepatology, Nagoya University Graduate School of Medicine kn-affil= affil-num=14 en-affil=Department of Biostatistics, Nagoya University Graduate School of Medicine kn-affil= affil-num=15 en-affil=Department of Biostatistics, Nagoya University Graduate School of Medicine kn-affil= en-keyword=LRG kn-keyword=LRG en-keyword=Biomarker kn-keyword=Biomarker en-keyword=Crohn’s disease kn-keyword=Crohn’s disease END start-ver=1.4 cd-journal=joma no-vol=1873 cd-vols= no-issue=2 article-no= start-page=120091 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202602 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=SPRED2 controls the severity of cisplatin-induced acute kidney injury by inhibiting ERK activation and TNFα production in mice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cisplatin is an effective chemotherapeutic agent used to treat solid tumors, but its clinical use is limited by acute kidney injury (AKI), in which ERK signaling plays a crucial role. Here, we investigated whether Sprouty-related EVH1 domain-containing protein 2 (SPRED2), an endogenous inhibitor of the Ras/Raf/ERK pathway, protects against cisplatin-induced AKI. Spred2−/− mice showed more severe renal injury and stronger ERK activation than wild-type (WT) mice, whereas pretreatment with the MEK inhibitor U0126 markedly attenuated the injury. In HK-2 cells (proximal tubular cells), SPRED2 knockdown enhanced cisplatin-induced apoptosis and caspase-3 activation, accompanied by decreased Bcl-2 expression. Spred2−/− kidneys displayed increased macrophage infiltration and elevated Tnfα, Il1b, and Ccl2 expression. Neutralization of TNFα with anti-TNFα antibody ameliorated renal injury and reduced the levels of Il1b and Ccl2 mRNA in Spred2−/− mice. In vitro, TNFα slightly decreased the viability of control and SPRED2 knockdown HK-2 cells without cisplatin treatment, but the decreased viability was augmented in SPRED2 knockdown cells by cisplatin. Immunohistochemistry revealed that macrophages were the predominant TNFα-positive cell population. Bone marrow–derived macrophages from Spred2−/− mice produced higher levels of TNFα in response to cisplatin compared with control cells, and this increase was markedly suppressed by U0126.
These findings indicate that endogenous SPRED2 protects kidneys from cisplatin-induced AKI by limiting ERK activation, tubular apoptosis, and TNFα-mediated inflammation. en-copyright= kn-copyright= en-aut-name=YangXu en-aut-sei=Yang en-aut-mei=Xu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HeJiali en-aut-sei=He en-aut-mei=Jiali kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GaoTong en-aut-sei=Gao en-aut-mei=Tong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujisawaMasayoshi en-aut-sei=Fujisawa en-aut-mei=Masayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OharaToshiaki en-aut-sei=Ohara en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KunkelSteven L. en-aut-sei=Kunkel en-aut-mei=Steven L. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YoshimuraTeizo en-aut-sei=Yoshimura en-aut-mei=Teizo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= affil-num=1 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Pathology, University of Michigan Medical School kn-affil= affil-num=7 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Pathology and Experimental Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Cisplatin kn-keyword=Cisplatin en-keyword=ERK kn-keyword=ERK en-keyword=Macrophage kn-keyword=Macrophage en-keyword=SPRED2 kn-keyword=SPRED2 en-keyword=TNFα kn-keyword=TNFα END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=12 article-no= start-page=1455 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251203 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Roles of ROS and NO in Plant Responses to Individual and Combined Salt Stress and Waterlogging en-subtitle= kn-subtitle= en-abstract= kn-abstract=During the climate change era, plants are increasingly exposed to multiple environmental challenges occurring simultaneously or sequentially. Among these, salt stress and waterlogging are two major factors that severely constrain crop productivity worldwide and often occur together. To survive under such conditions, plants have evolved sophisticated systems to scavenge harmful levels of reactive oxygen species (ROS). Despite their cytotoxic potential, ROS also act as key signaling molecules that interact with nitric oxide (NO), Ca2+, protein kinases, ion homeostasis pathways, and plant hormones. These signaling and acclimatory mechanisms are closely associated with the functions of energy-regulating organelles—chloroplasts and mitochondria—which are major sources of ROS under both individual and combined stresses. While many of these responses are shared between salt stress, waterlogging and their combination, it is likely that specific signaling mechanisms are uniquely activated when both stresses occur together—mechanisms that cannot be inferred from responses to each stress alone. Such specificity may depend on precise coordination among organelle-derived signals and the tight regulation of their cross-communication. Within this network, ROS and NO likely serve as central hubs, fine-tuning the integration of multiple signaling pathways that enable plants to adapt to complex and fluctuating stress environments. en-copyright= kn-copyright= en-aut-name=AneeTaufika Islam en-aut-sei=Anee en-aut-mei=Taufika Islam kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SewelamNasser A. en-aut-sei=Sewelam en-aut-mei=Nasser A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=BautistaNonnatus S. en-aut-sei=Bautista en-aut-mei=Nonnatus S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HirayamaTakashi en-aut-sei=Hirayama en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= affil-num=1 en-affil=Department of Materials and Life Sciences, Faculty of Science and Technology, Sophia University kn-affil= affil-num=2 en-affil=Botany Department, Faculty of Science, Tanta University kn-affil= affil-num=3 en-affil=Institute of Biological Sciences, College of Arts and Sciences, University of the Philippines Los Baños kn-affil= affil-num=4 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=5 en-affil=Department of Materials and Life Sciences, Faculty of Science and Technology, Sophia University kn-affil= en-keyword=chloroplasts kn-keyword=chloroplasts en-keyword=mitochondria kn-keyword=mitochondria en-keyword=nitric oxide (NO) kn-keyword=nitric oxide (NO) en-keyword=reactive oxygen species (ROS) kn-keyword=reactive oxygen species (ROS) en-keyword=salt stress kn-keyword=salt stress en-keyword=stress combination waterlogging kn-keyword=stress combination waterlogging END start-ver=1.4 cd-journal=joma no-vol=57 cd-vols= no-issue=S 01 article-no= start-page=E1355 end-page=E1356 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251127 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Antegrade enteral stenting for afferent loop syndrome using the double-guidewire technique via endoscopic ultrasound-guided hepaticogastrostomy en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=FujiiYuki en-aut-sei=Fujii en-aut-mei=Yuki 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=UchidaDaisuke en-aut-sei=Uchida en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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=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=Department of Endoscopy, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Endoscopy, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital, Okayama, Japan kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= 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=20251127 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Avoiding splenectomy in splenic sclerosing angiomatoid nodular transformation through endoscopic ultrasound-guided tissue acquisition: a 36-month follow-up case report en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 48-mm splenic mass was incidentally discovered in a 78-year-old man upon computed tomography. Follow-up imaging at 12 months revealed enlargement to 60 mm, prompting endoscopic ultrasound-guided tissue acquisition with a 22-gauge needle. Histopathological analysis confirmed that it was a sclerosing angiomatoid nodular transformation. The patient was asymptomatic and had no hematologic abnormalities; therefore, splenectomy was not performed. After biopsy, the lesion regressed from 60 mm to 46 mm, possibly owing to hematoma formation or vascular disruption, and remained stable during 36 months of follow-up. Although splenectomy has been performed in most reported cases of sclerosing angiomatoid nodular transformation because of diagnostic uncertainty, a few recent reports have demonstrated that sclerosing angiomatoid nodular transformation can be diagnosed by endoscopic ultrasound-guided tissue acquisition, thereby avoiding splenectomy. This case highlights the diagnostic utility of endoscopic ultrasound-guided tissue acquisition and supports spleen-preserving management for biopsy-proven sclerosing angiomatoid nodular transformation. en-copyright= kn-copyright= en-aut-name=OkuyamaTakaki en-aut-sei=Okuyama en-aut-mei=Takaki 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=MorimotoKosaku en-aut-sei=Morimoto en-aut-mei=Kosaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KimuraShogo en-aut-sei=Kimura en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyakeTakayoshi en-aut-sei=Miyake en-aut-mei=Takayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SatomiTakuya en-aut-sei=Satomi en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakeiKensuke en-aut-sei=Takei en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=InoueShogo en-aut-sei=Inoue en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= affil-num=1 en-affil=Department of Internal Medicine, Tsuyama Chuo Hospital kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Internal Medicine, Tsuyama Chuo Hospital kn-affil= affil-num=4 en-affil=Department of Internal Medicine, Tsuyama Chuo Hospital kn-affil= affil-num=5 en-affil=Department of Pathology, Tsuyama Chuo Hospital kn-affil= affil-num=6 en-affil=Department of Internal Medicine, Tsuyama Chuo Hospital kn-affil= affil-num=7 en-affil=Department of Internal Medicine, Tsuyama Chuo Hospital kn-affil= affil-num=8 en-affil=Department of Internal Medicine, Tsuyama Chuo Hospital kn-affil= affil-num=9 en-affil=Department of Internal Medicine, Tsuyama Chuo Hospital kn-affil= en-keyword=Sclerosing angiomatoid nodular transformation kn-keyword=Sclerosing angiomatoid nodular transformation en-keyword=Spleen kn-keyword=Spleen en-keyword=Endoscopic ultrasound-guided tissue acquisition kn-keyword=Endoscopic ultrasound-guided tissue acquisition en-keyword=Conservative management kn-keyword=Conservative management en-keyword=Biopsy kn-keyword=Biopsy 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=20251123 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A rare case of supratentorial ependymosarcoma harboring ZFTA::RELA fusion en-subtitle= kn-subtitle= en-abstract= kn-abstract=Ependymosarcoma is an exceedingly rare variant of ependymoma characterized by a mixture of ependymomatous and sarcomatous components. We report a case of supratentorial ependymosarcoma harboring a ZFTA::RELA fusion in a 10-year-old girl. Histologically, the tumor comprised an ependymomatous component resembling clear cell ependymoma and a sarcomatous component. ZFTA::RELA fusion was confirmed in both components. Genome-wide methylation profiling classified both components as supratentorial ependymoma, ZFTA fusion–positive by the German Cancer Research Center (DKFZ) CNS tumor classifier v12b8. However, their copy number alteration profiles were distinct. The ependymomatous component exhibited a gain of chromosome 1q and a loss of chromosomes 1p, 9, and 19q, while the sarcomatous component showed a loss of chromosome 14. These findings suggest that both components may have differentiated from a common precursor despite their distinct morphologies. The patient underwent gross total resection followed by adjuvant chemoradiotherapy and remains recurrence-free eight years post-treatment. Further investigation of additional cases is warranted to better understand the pathogenesis of this rare tumor. en-copyright= kn-copyright= en-aut-name=MatsumotoYuji en-aut-sei=Matsumoto en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SurugaYasuki en-aut-sei=Suruga en-aut-mei=Yasuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SatomiKaishi en-aut-sei=Satomi en-aut-mei=Kaishi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=InoueYohei en-aut-sei=Inoue en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HattoriYasuhiko en-aut-sei=Hattori en-aut-mei=Yasuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=KurozumiKazuhiko en-aut-sei=Kurozumi en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NobusawaSumihito en-aut-sei=Nobusawa en-aut-mei=Sumihito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HiratoJunko en-aut-sei=Hirato en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 ORCID= en-aut-name=YanaiHiroyuki en-aut-sei=Yanai en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 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=12 ORCID= en-aut-name=IchimuraKoichi en-aut-sei=Ichimura en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=IchikawaTomotsugu en-aut-sei=Ichikawa en-aut-mei=Tomotsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 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=15 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=16 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Pathology, Faculty of Medicine, Kyorin University kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Department of Neurological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of Neurological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Department of Neurosurgery, Hamamatsu University Hospital kn-affil= affil-num=8 en-affil=Department of Human Pathology, Gunma University School of Medicine kn-affil= affil-num=9 en-affil=Department of Pathology, Public Tomioka General Hospital kn-affil= affil-num=10 en-affil=Department of Pathology, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Pathology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=12 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=13 en-affil=Department of Pathology, Faculty of Medicine, Kyorin University kn-affil= affil-num=14 en-affil=Department of Neurosurgery, Kagawa Prefectural Central Hospital kn-affil= affil-num=15 en-affil=Department of Neurological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=16 en-affil=Department of Neurological Surgery, Dentistry, and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= en-keyword=Ependymoma kn-keyword=Ependymoma en-keyword=Ependymosarcoma kn-keyword=Ependymosarcoma en-keyword=ZFTA kn-keyword=ZFTA en-keyword=RELA kn-keyword=RELA en-keyword=Methylation profiling kn-keyword=Methylation profiling END start-ver=1.4 cd-journal=joma no-vol=64 cd-vols= no-issue=6 article-no= start-page=104265 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202512 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Novel leukocytapheresis method using highly concentrated sodium citrate solution for the manufacturing of tisagenlecleucel en-subtitle= kn-subtitle= en-abstract= kn-abstract=For the manufacturing of tisagenlecleucel (tisa-cel) requires the non-mobilized mononuclear cell collection (MNC). CD3+ cell collection is performed using the same protocol as autologous peripheral blood stem cell harvest (auto-PBSCH), but this procedure necessitates the same target CD3+ cell yields regardless of age or body weight, which may take several days especially in pediatric and small female patients with low white blood cell counts. We previously demonstrated a novel method using highly concentration sodium citrate (HSC), which reduced the need for an anticoagulant (AC) solution and shortened the procedure time in auto-PBSCH. This novel method was expected to offer advantages for smaller patients, prompting us to investigate its application in leukocytapheresis for the manufacturing of tisa-cel. We retrospectively analyzed consecutive leukocytapheresis data obtained using Spectra Optia continuous MNC mode between November 2022 and June 2024 at our institution (n = 9). In six of nine patients, pre-leukocytapheresis CD3+ cell counts were less than 500 /μL, but all could obtain the target CD3+ cell yields in one day upon processing blood volume adjustment. When we compared patients who had received CD3+ cell collection using normal-concentration sodium citrate (NSC) as our previously reported using propensity score-matched pair analysis, the total AC solution volume was significantly lower (1168 vs. 316 mL, p < 0.001) and procedure time was significantly shorter (254 vs. 228 min, p = 0.04) in the HSC group compared to the NSC group. In conclusion, this procedure was also useful for non-mobilized MNC. Our findings warrant validation in a larger patient cohort. en-copyright= kn-copyright= en-aut-name=KitamuraWataru en-aut-sei=Kitamura en-aut-mei=Wataru 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=AbeMasaya en-aut-sei=Abe en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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=5 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=6 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=7 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=8 ORCID= affil-num=1 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=6 en-affil=Division of Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= en-keyword=Chimeric antigen receptor T cell therapy kn-keyword=Chimeric antigen receptor T cell therapy en-keyword=Anticoagulant kn-keyword=Anticoagulant en-keyword=Acid citrate dextrose solution A kn-keyword=Acid citrate dextrose solution A en-keyword=Highly concentrated sodium citrate kn-keyword=Highly concentrated sodium citrate END start-ver=1.4 cd-journal=joma no-vol=65 cd-vols= no-issue=9 article-no= start-page=1662 end-page=1672 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250725 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Novel method for autologous peripheral blood stem cell harvest using highly concentrated sodium citrate solution replacing acid citrate dextrose solution A en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: As the processed blood volume increases, a larger amount of anticoagulant (AC) is required, which leads to a serious issue of fluid dilution in large-volume leukocytapheresis (defined as ≥3-fold total blood volume). We previously reported a novel method for allogeneic peripheral blood stem cell harvest (PBSCH) using highly concentrated sodium citrate (HSC; 5.32%), which shortened the procedure time and reduced the need for an AC solution without heparin. In this study, we extended this novel method to autologous PBSCH (auto-PBSCH) and compared it with patients who received auto-PBSCH using normal concentrated sodium citrate (NSC; 2.2%).
Study Design and Methods: We retrospectively analyzed consecutive auto-PBSCH data obtained using the Spectra Optia continuous mononuclear cell collection mode between May 2017 and May 2025 at our institution.
Results: Leukocytapheresis was performed using NSC in 36 patients and HSC in 22. In the HSC group, patients tended to be younger, had significantly lower body weight, and had significantly fewer hematopoietic tumors as primary diseases compared to the NSC group. After propensity score-matched cohort adjusted for patient background, the total amount of AC solution was significantly lower (694 [range, 77–1648] vs. 298 mL [range, 64–797], p = .02), and procedure time was significantly shorter (224 [range, 117–395] vs. 181 min [range, 103–309], p = .048) in the HSC group. Furthermore, the loss rates of magnesium and potassium were lower in the HSC group.
Conclusion: This novel leukocytapheresis method demonstrated the efficacy and safety in auto-PBSCH, while minimizing the patient burden. en-copyright= kn-copyright= en-aut-name=KitamuraWataru en-aut-sei=Kitamura en-aut-mei=Wataru 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=AbeMasaya en-aut-sei=Abe en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=ShimonoJoji en-aut-sei=Shimono en-aut-mei=Joji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=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= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= affil-num=1 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=7 en-affil=Division of Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= en-keyword=acid citrate dextrose solution A kn-keyword=acid citrate dextrose solution A en-keyword=anticoagulant kn-keyword=anticoagulant en-keyword=autologous kn-keyword=autologous en-keyword=highly concentrated sodium citrate kn-keyword=highly concentrated sodium citrate en-keyword=peripheral blood stem cell kn-keyword=peripheral blood stem cell END start-ver=1.4 cd-journal=joma no-vol=82 cd-vols= no-issue=2 article-no= start-page=26-1566 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=2026 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=放射線治療装置の回転座標系誤差が軸外targetの照射精度に及ぼす影響とTG142のトレランスの評価 en-subtitle= kn-subtitle= en-abstract=Purpose: The aim of this study was to quantitatively evaluate the impact of gantry, collimator, and couch rotational errors in a linear accelerator on the irradiation accuracy of off-isocenter targets, and to assess the validity of the rotational error tolerance (±1.0°) specified in American Association of Physicists in Medicine TG142. Methods: Using an Elekta linear accelerator (Elekta, Stockholm, Sweden) and the MultiMet-WL QA phantom (Sun Nuclear, Melbourne, FL, USA), an off-isocenter Winston–Lutz test was performed on six targets. In addition to baseline measurements, six conditions were evaluated by intentionally introducing rotational errors of +0.5° and +1.0° in the collimator, gantry, and couch. The vector distance (S value) between the field center and the target center, as well as positional deviations in each direction (gantry-target: GT, left-right: LR, anterior-posterior: AP), were analyzed. Results: Targets located farther from the isocenter exhibited more significant positional deviations. The collimator rotation had the greatest impact; at 7 cm from the isocenter, even a 0.5° error resulted in a maximum S value of 1.24 mm. Couch rotation had the next largest effect, while gantry rotation had relatively smaller effects, likely because most targets were located near the gantry’s rotational axis. The rotational errors mainly caused geometric deviations with direction-dependent positional shifts. Conclusion: The effects of the collimator and couch were substantial, with positional deviations exceeding 1 mm even for a 0.5° rotation error. The influence of the gantry was relatively small and dependent on the target configuration. For irradiation of off-axis targets, the TG142 tolerance of ±1.0° should be regarded as a minimum standard that must be strictly observed regardless of the type of linear accelerator. However, depending on the target arrangement, clinically adequate margins may not be ensured. These findings suggest the necessity of applying stricter criteria according to target configuration and emphasize the importance of regular quality assurance. kn-abstract=【目的】放射線治療装置の回転座標系の誤差が軸外targetの照射精度に及ぼす影響を定量的に評価し,TG142における回転座標系誤差(±1.0°)のトレランスの妥当性を検討する.【方法】Elekta社製放射線治療装置(Elekta, Stockholm, Sweden)とMultiMet-WL QAファントム(Sun Nuclear, Melbourne, FL, USA)を用いて,6個のtargetに対してoff isocenterのWinston–Lutz test(WL test)を実施した.Baselineの測定に加え,意図的にcollimator,gantry,couchに+0.5°, +1.0°回転誤差を加えた6条件で測定を行い,照射野中心とtarget中心のベクトル距離(S値)および各方向(gantry-target: GT, left-right: LR, anterior-posterior: AP)の位置ずれを解析した.【結果】Isocenterからの距離が大きいtargetほど位置ずれが顕著であった.特にcollimator回転誤差の影響が最も大きく,isocenterから7 cm離れたtargetでは0.5°の回転誤差でもS値が最大1.24 mmに達した.次に影響が大きかったのはcouch回転であり,gantry回転はtargetの配置が回転軸に近いものが多く相対的に影響が少なかった.回転座標系の誤差は幾何学的誤差の影響が強く,位置ずれに方向依存性があった.【結語】Collimatorやcouchの影響が大きく,0.5°の誤差でも1 mm以上の位置ずれが生じることがあった.Gantryの影響はtargetの配置依存があり,相対的に小さかった.軸外targetの照射において,TG142の±1.0°のトレランスは放射線治療装置の種類にかかわらず最低限遵守するべき基準であり,targetの配置次第では臨床的に十分なマージンを保証できない可能性が示された.Target配置に応じたより厳格な基準と定期的quality assurance(QA)の重要性が示唆された. en-copyright= kn-copyright= en-aut-name=NakayamaTakahiro en-aut-sei=Nakayama en-aut-mei=Takahiro kn-aut-name=中山貴裕 kn-aut-sei=中山 kn-aut-mei=貴裕 aut-affil-num=1 ORCID= en-aut-name=TanabeYoshinori en-aut-sei=Tanabe en-aut-mei=Yoshinori kn-aut-name=田辺悦章 kn-aut-sei=田辺 kn-aut-mei=悦章 aut-affil-num=2 ORCID= en-aut-name=FujiiYasushi en-aut-sei=Fujii en-aut-mei=Yasushi kn-aut-name=藤井康志 kn-aut-sei=藤井 kn-aut-mei=康志 aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Radiology, Public Mutual Aid Association Chugoku Central Hospital kn-affil=公立学校共済組合中国中央病院放射線科 affil-num=2 en-affil=Department of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil=岡山大学学術研究院保健学域放射線技術科学専攻 affil-num=3 en-affil=Department of Radiology, Public Mutual Aid Association Chugoku Central Hospital kn-affil=公立学校共済組合中国中央病院放射線科 en-keyword=off-isocenter Winston–Lutz test kn-keyword=off-isocenter Winston–Lutz test en-keyword=rotation error kn-keyword=rotation error en-keyword=off-axis targets kn-keyword=off-axis targets en-keyword=Elekta kn-keyword=Elekta en-keyword=TG142 kn-keyword=TG142 END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=10 article-no= start-page=e95808 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251031 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Risk Stratification for the Prediction of Skeletal-Related Events in Patients With Bone Metastases From Non-small Cell Lung Cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Skeletal-related events (SREs) frequently occur in patients with bone metastases from non-small cell lung cancer (NSCLC). This study aimed to identify risk factors for SREs in patients with NSCLC. Based on these factors, we also aimed to stratify patients into subgroups to facilitate the assessment of SRE risk. This retrospective analysis used medical records of 139 patients with NSCLC bone metastases who received treatment at our institution between 2011 and 2014. The incidence of SREs was assessed, and SRE-free survival was analyzed using the Kaplan-Meier method. Clinical information collected at registration was assessed to identify factors associated with the onset of SREs within six months. Univariate analysis was performed using Fisher’s exact test, and multivariate analysis was performed using Cox regression. Of the 139 patients, 36 (26%) developed SREs after registration. The SRE-free survival rates were 80% and 64% at 6 and 12 months, respectively. The univariate and multivariate analyses revealed that the absence of epidermal growth factor receptor (EGFR) mutations or anaplastic lymphoma kinase (ALK) rearrangement (hazard ratio (HR): 4.51, 95% confidence interval (CI): 1.32-15.7, p = 0.017) and a lactate dehydrogenase (LDH) level ≥400 U/L (HR: 8.08, 95% CI: 1.78-36.6, p = 0.0067) were risk factors for SRE presentation within six months. Patients were classified into the following three subgroups: with EGFR mutation or ALK rearrangement and LDH level <400 U/L; without EGFR mutation or ALK rearrangement and LDH level <400 U/L; with/without EGFR mutation or ALK rearrangement and LDH level ≥400 U/L. The corresponding six-month SRE-free survival rates were 92%, 69%, and 34%, respectively, showing significant differences (p < 0.001). Close monitoring is recommended for patients with LDH levels ≥400 U/L in daily clinical practice, particularly with the help of the proficiency of orthopedic and radiological experts, to prevent complications such as pathological fractures and paraplegia. en-copyright= kn-copyright= en-aut-name=SakamotoYoshihiro en-aut-sei=Sakamoto en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 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=4 ORCID= en-aut-name=SugiharaShinsuke en-aut-sei=Sugihara en-aut-mei=Shinsuke 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 Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Orthopedic Surgery, Shikoku Cancer Center kn-affil= affil-num=6 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=anaplastic lymphoma kinase kn-keyword=anaplastic lymphoma kinase en-keyword=bone metastases kn-keyword=bone metastases en-keyword=epidermal growth factor receptor-tyrosine kinase kn-keyword=epidermal growth factor receptor-tyrosine kinase en-keyword=lactate dehydrogenase kn-keyword=lactate dehydrogenase en-keyword=non-small cell lung cancer kn-keyword=non-small cell lung cancer en-keyword=skeletal related events kn-keyword=skeletal related events END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=8 article-no= start-page=e90112 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250814 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Conversion to Hip Arthroplasty After Internal Fixation Failure in an Intertrochanteric Femoral Fracture: A Case Report en-subtitle= kn-subtitle= en-abstract= kn-abstract=Intertrochanteric femoral fractures are mainly managed by internal fixation. However, failures such as over-telescoping, cut-out, nonunion, or implant failure can occur, especially in osteoporotic elderly patients. We report the case of a patient in whom we performed artificial hip replacement surgery after fixation failure following internal fixation of an intertrochanteric femoral fracture. We report the case of an 85-year-old woman who sustained a left intertrochanteric femoral fracture treated with a dynamic hip screw (DHS). One week postoperatively, radiographs revealed over-telescoping of the lag screw. The patient did not complain of pain, but she underwent conversion to cemented bipolar hemiarthroplasty under general anesthesia. One possible cause of over-telescoping of the lag screw after surgery was that the longitudinal fracture line in the calcar of the proximal bone fragment, as seen in the initial CT image, may have extended horizontally at the neck level. During surgery, a fracture at the same site caused the anterior medial fragment to fail, resulting in a coronal shear fracture and fixation failure. When a longitudinal fracture line is observed in the calcar of the proximal fragment, it is necessary to keep in mind that it may extend horizontally at the neck level. en-copyright= kn-copyright= en-aut-name=FukuokaShiro en-aut-sei=Fukuoka en-aut-mei=Shiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=InoueTomoo en-aut-sei=Inoue en-aut-mei=Tomoo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakahashiMotoki en-aut-sei=Takahashi en-aut-mei=Motoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KawasakiKeisuke en-aut-sei=Kawasaki en-aut-mei=Keisuke 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= affil-num=1 en-affil=Department of Orthopedics, Kagawa Prefectural Central Hospital kn-affil= affil-num=2 en-affil=Department of Orthopedics, Kagawa Prefectural Central Hospital kn-affil= affil-num=3 en-affil=Department of Orthopedics, Kagawa Prefectural Central Hospital kn-affil= affil-num=4 en-affil=Department of Orthopedic Surgery, Kagawa Prefectural Central Hospital kn-affil= affil-num=5 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= en-keyword=arthroplasty kn-keyword=arthroplasty en-keyword=coronal shear fracture kn-keyword=coronal shear fracture en-keyword=double jaws sign kn-keyword=double jaws sign en-keyword=fixation failure kn-keyword=fixation failure en-keyword=intertrochanteric femoral fracture kn-keyword=intertrochanteric femoral fracture END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=6 article-no= start-page=e85955 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=Clinical Outcomes and Biomechanical Evaluation of the Cement-Catching Screw Technique for Osteoporotic Vertebral Fractures en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: We developed a cement-catching screw (CCS) technique for pedicle screw insertion into hardened cement, connecting anterior and posterior vertebral elements during balloon kyphoplasty (BKP) for osteoporotic vertebral fractures (OVFs). This study reports the CCS technique, clinical outcomes, and biomechanical properties.
Methods: This retrospective study included 59 patients (20 men, 39 women; mean age, 77.4 ± 8.7 years) who underwent BKP with one-above-one-below posterior fixation for OVFs between 2020 and 2023. Patients were divided into CCS (−) (without intermediate screws, n = 28) and CCS (+) (with intermediate CCSs, n = 31) groups. Clinical and radiographic outcomes, including activities of daily living, vertebral wedge angle (VWA), surgical level Cobb angle (CA), anterior vertebral body height (AVBH), screw loosening, pullout, and adjacent vertebral fractures, were evaluated preoperatively, postoperatively, and at the final follow-up (≥6 months). Biomechanical pullout strength was assessed at different insertion depths (5, 10, and 15 mm) using polymethylmethacrylate cement.
Results: No significant differences were observed between groups in age, sex, follow-up duration, or blood loss; however, the operation time was significantly longer in the CCS (+) group than in the CCS (−) group (P < 0.0001). Radiographic outcomes showed no significant differences in the VWA, CA, AVBH, adjacent vertebral fracture rates, and reoperation rates. However, the incidence of adjacent pedicle screws loosening and pullout was significantly higher in the CCS (−) group than in the CCS (+) group (P = 0.046 and 0.0084, respectively). The correction loss of the CA was significantly lower in the CCS (+) group (CCS (−), 5.6° ± 4.8°; CCS (+), 3.5° ± 4.8°, P = 0.023). The biomechanical test revealed pullout strengths of 683 ± 164, 2231 ± 208, and 3477 ± 393 N for insertion depths of 5, 10, and 15 mm, respectively, with significant increases by depth (P = 0.003 and 0.009).
Conclusions: The CCS technique improves anterior-posterior vertebral body stability, enhances fixation strength, and contributes to better surgical outcomes in OVFs treatment. en-copyright= kn-copyright= en-aut-name=ShitozawaHisakazu en-aut-sei=Shitozawa en-aut-mei=Hisakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MisawaHaruo en-aut-sei=Misawa en-aut-mei=Haruo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=JokoRyoji en-aut-sei=Joko en-aut-mei=Ryoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakahashiMasaya en-aut-sei=Takahashi en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=ShiozakiYasuyuki en-aut-sei=Shiozaki en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TetsunagaTomoko en-aut-sei=Tetsunaga en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= en-aut-name=NakamichiRyo en-aut-sei=Nakamichi en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=UedaMasataka en-aut-sei=Ueda en-aut-mei=Masataka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=TakatoriRyo en-aut-sei=Takatori en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=YamashitaKazutaka en-aut-sei=Yamashita en-aut-mei=Kazutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 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=14 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Science of Functional Recovery and Reconstruction, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Ryusou Orthopaedic Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Japanese Red Cross Okayama Hospital kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Japanese Red Cross Okayama Hospital kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Orthopaedic surgery, Mitoyo General Hospital kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Sports Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University 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, Science of Functional Recovery and Reconstruction, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Orthopaedic Surgery, Science of Functional Recovery and Reconstruction, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Orthopaedic Surgery, Science of Functional Recovery and Reconstruction, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=14 en-affil=Department of Orthopaedic Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=balloon kyphoplasty kn-keyword=balloon kyphoplasty en-keyword=cement-catching screw kn-keyword=cement-catching screw en-keyword=intermediate screws kn-keyword=intermediate screws en-keyword=osteoporotic vertebral fractures kn-keyword=osteoporotic vertebral fractures en-keyword=pullout strength kn-keyword=pullout strength END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=3 article-no= start-page=e80656 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250316 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Case of Charcot Spine Arthropathy at the Lumbosacral Level in a Patient With Ankylosis of the Spine en-subtitle= kn-subtitle= en-abstract= kn-abstract=Charcot spinal arthropathy, a rare refractory progressive disease, is characterized by symptoms such as pain, deformity, and neurological impairment, which can significantly reduce functional ability, quality of life, and life expectancy. We report a case of Charcot spine at the L5/S1 level with long segment ankylosis to the L5 vertebra. We first performed thorough debridement via a posterior approach. We used antibiotic-containing cement as a spacer to fill the dead space, facilitating the second surgery approach. In the second surgery, transdiscal screws, which have a low profile and strong force, were used as anchors, and bulk bone harvested from both iliac bones was grafted to the intervertebral space. The lumbosacral alignment was kyphotic, and the patient could sit and move independently. Disimpaction was impossible, and a stoma had to be created. en-copyright= kn-copyright= en-aut-name=OdaYoshiaki en-aut-sei=Oda en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=TetsunagaTomoko en-aut-sei=Tetsunaga en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=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= affil-num=1 en-affil=Department of Orthopedic Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Musculoskeletal Traumatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University 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, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Orthopedic Surgery, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=ankylosing spine kn-keyword=ankylosing spine en-keyword=charcot spine kn-keyword=charcot spine en-keyword=charcot spine arthropathy kn-keyword=charcot spine arthropathy en-keyword=lumbosacral segment kn-keyword=lumbosacral segment en-keyword=paraplegia kn-keyword=paraplegia en-keyword=transdiscal screw kn-keyword=transdiscal screw END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=1 article-no= start-page=e77632 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250118 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Mid-term Clinical and Radiographic Outcomes of the Actis Total Hip System: A Retrospective Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction
Implant technology for total hip arthroplasty (THA) was developed to improve hip function and patient satisfaction. Actis (DePuy Synthes, Warsaw, IN, USA) is a short fit-and-fill titanium stem, with a medial-collared and triple-taper (MCTT) geometry, that is fully coated with hydroxyapatite (HA). We evaluated the radiographic and clinical outcomes of the Actis Total Hip System during a mean follow-up of five years.
Patients and methods
We retrospectively analyzed data from 80 patients (14 male and 66 female, mean age: 65 ± 8.4 years) who underwent primary THA using Actis stems (anterolateral approach, 60 hips; posterior approach, 20 hips). Radiographs were obtained postoperatively and at the time of the final examination. Radiographic assessments included the alignment of the femoral stem, spot welds, stress shielding, cortical hypertrophy, subsidence (>2 mm), radiolucent line, pedestal formation, Dorr type, canal fill ratio (CFR), and stem fixation. Clinical evaluation included the Japanese Orthopaedic Association Hip-Disease Evaluation Questionnaire (JHEQ) and Harris Hip Score (HHS).
Results
The mean follow-up period was 64.0 ± 6.0 months. No significant differences were observed in the alignment of the femoral components between approaches. Of the 80 hips, 53 (66.3%) showed radiographic signs of stem osseointegration, predominantly in the mid-distal region of the stem at the final follow-up. Multiple logistic regression analysis revealed that younger age and a higher CFR (20 mm proximal to the lesser trochanter) were associated with the presence of spot welds. Mild stress shielding occurred in 25 hips (31.3%), and no patient experienced severe stress shielding. All stems were fixed by bone on growth. The JHEQ and HHS significantly improved at the final assessment.
Conclusion
At the five-year follow-up, patients who received the Actis Total Hip System during THA had good radiographic and clinical outcomes.

Rupture of the extensor pollicis longus (EPL) tendon, essential for thumb extension, is a notable complication, especially in non-displaced DRFs. Several mechanisms, such as local adhesion, ischemic atrophy, and tendon laceration, are associated with EPL tendon rupture. This multicenter retrospective study aims to identify risk factors for EPL tendon rupture in non-displaced DRFs.
Materials and methods: The study reviewed 20 cases of EPL tendon rupture and 52 control cases from 2005 to 2022, excluding those who underwent surgery or had incomplete computed tomography (CT) data. We investigated age, sex, location of fracture line, and the morphology of Lister’s tubercle as variables. Logistic regression and decision tree analyses were employed to determine the risk factors for EPL tendon rupture based on these variables.
Results: Fracture lines distal to Lister’s tubercle and specific shapes of Lister’s tubercle, characterized by shallow peak height and a higher radial peak than the ulnar peak, increased the risk of EPL tendon rupture. Decision tree analysis confirmed them as major risk factors. There was a significant difference in the predicted probability rate of tendon rupture between the case with these factors and those without them (P < 0.001). Conversely, the location and size of Lister’s tubercle did not affect the incidence of EPL tendon rupture.
Conclusion: The location of fracture line and the shape of Lister’s tubercle are key factors influencing EPL tendon rupture in non-displaced DRFs. Understanding these factors can help orthopedic surgeons predict and prevent EPL tendon ruptures, improving patient outcomes following these fractures. en-copyright= kn-copyright= en-aut-name=SaitoTaichi en-aut-sei=Saito en-aut-mei=Taichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FurutaniTomoki en-aut-sei=Furutani en-aut-mei=Tomoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakamichiRyo en-aut-sei=Nakamichi en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakaharaRyuichi en-aut-sei=Nakahara en-aut-mei=Ryuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KondoHidenori en-aut-sei=Kondo en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=ImataniJunya en-aut-sei=Imatani en-aut-mei=Junya 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 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, Kagawa Rosai Hospital kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Kousei Hospital kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Saiseikai General Hospital 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=Distal radius fracture kn-keyword=Distal radius fracture en-keyword=Extensor pollicis longus tendon kn-keyword=Extensor pollicis longus tendon en-keyword=Risk factor kn-keyword=Risk factor END start-ver=1.4 cd-journal=joma no-vol=145 cd-vols= no-issue=1 article-no= start-page=373 end-page= 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=Changes in the anatomical positions of the femoral nerve and artery in the lateral and supine positions: a multicenter retrospective study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction Femoral nerve palsy and femoral artery injury are serious complications of total hip arthroplasty. However, few studies have compared the anatomical positions of these structures in different patient positions. This study aimed to compare the anatomical positions of the femoral nerve and artery in the lateral and supine positions.
Materials and methods This multicenter retrospective study included 111 patients who underwent lateral and supine computed tomography (CT) from 2016 to 2023. CT images were reconstructed in the anterior pelvic plane. The horizontal distance from the anterior margin of the acetabulum to the femoral nerve (Distance N) and femoral artery (Distance A) was measured. The difference in Distance N between the two positions (ΔLateral–supine Distance N) was calculated by subtracting the supine value from the lateral value.
Results The average Distance N was 26.5 ± 5.1 mm in the lateral position and 21.1 ± 4.4 mm in the supine position, with the nerve located significantly closer to the acetabulum in the supine position (P < 0.001). Similarly, the average Distance A was 26.8 ± 5.4 mm in the lateral position and 20.4 ± 4.9 mm in the supine position (P < 0.001). Multiple regression analysis showed that Distance N in the lateral position was significantly shorter in female patients and those with low body weight. In addition, low body weight correlated with a smaller ΔLateral–supine Distance N.
Conclusions The femoral nerve and artery are located closer to the anterior margin of the acetabulum in the supine position than in the lateral position. Low body weight was an independent predictor of shorter Distance N in both positions and a smaller ΔLateral–supine Distance N. These findings underscore the importance of considering patient positioning during total hip arthroplasty, particularly in patients with low body weight, to reduce neurovascular risks. en-copyright=

sarcoma: an updated review en-subtitle= kn-subtitle= en-abstract= kn-abstract=In recent years, pembrolizumab has demonstrated significant efficacy in treating tumors characterized by a high tumor mutational burden and high microsatellite instability. Tropomyosin receptor kinase (TRK) inhibitors have shown considerable efficacy against tumors harboring neurotrophic receptor tyrosine kinase (NTRK) fusion genes, highlighting the growing importance of personalized medicine in cancer treatment. Advanced sequencing technologies enable the rapid analysis of numerous genetic abnormalities in tumors, facilitating the identification of patients with positive biomarkers. These advances have increased the likelihood of providing effective, tailored treatments. NTRK fusion genes are present in various cancer types, including sarcomas, and the TRK inhibitors larotrectinib and entrectinib have been effectively used for these malignancies. Consequently, the treatment outcomes for NTRK fusion-positive tumors have improved significantly, reflecting a shift toward more personalized therapeutic approaches. This review focuses on NTRK fusion-positive sarcomas and comprehensively evaluates their epidemiology, clinical features, and radiological and histological characteristics. We also investigated the treatment landscape, including the latest methodologies involving TRK inhibitors, and discussed the long-term efficacy of these inhibitors, and their optimal order of use. Notably, larotrectinib has demonstrated a high response rate in infantile fibrosarcoma, and its efficacy has been confirmed even in advanced cases. However, further research is warranted to optimize treatment duration and subsequent management strategies. The accumulation of clinical cases worldwide will play a pivotal role in refining the treatment approaches for tumors associated with NTRK fusion genes. en-copyright= kn-copyright= en-aut-name=KubotaYuta en-aut-sei=Kubota en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawanoMasanori en-aut-sei=Kawano en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IwasakiTatsuya en-aut-sei=Iwasaki en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ItonagaIchiro en-aut-sei=Itonaga en-aut-mei=Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KakuNobuhiro en-aut-sei=Kaku en-aut-mei=Nobuhiro 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= en-aut-name=TanakaKazuhiro en-aut-sei=Tanaka 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 Orthopaedic Surgery, Faculty of Medicine, Oita University kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Faculty of Medicine, Oita University kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Faculty of Medicine, Oita University kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Faculty of Medicine, Oita University kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Faculty of Medicine, Oita University kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery , Science of Functional Recovery and Reconstruction, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Faculty of Medicine, Oita University kn-affil= en-keyword=NTRK fusion-positive sarcoma kn-keyword=NTRK fusion-positive sarcoma en-keyword=larotrectinib kn-keyword=larotrectinib en-keyword=entrectinib kn-keyword=entrectinib en-keyword=infantile fibrosarcoma kn-keyword=infantile fibrosarcoma en-keyword=NTRK-rearranged spindle cell neoplasms kn-keyword=NTRK-rearranged spindle cell neoplasms END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=19 article-no= start-page=3144 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250927 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Utility of Same-Modality, Cross-Domain Transfer Learning for Malignant Bone Tumor Detection on Radiographs: A Multi-Faceted Performance Comparison with a Scratch-Trained Model en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: Developing high-performance artificial intelligence (AI) models for rare diseases like malignant bone tumors is limited by scarce annotated data. This study evaluates same-modality cross-domain transfer learning by comparing an AI model pretrained on chest radiographs with a model trained from scratch for detecting malignant bone tumors on knee radiographs. Methods: Two YOLOv5-based detectors differed only in initialization (transfer vs. scratch). Both were trained/validated on institutional data and tested on an independent external set of 743 radiographs (268 malignant, 475 normal). The primary outcome was AUC; prespecified operating points were high-sensitivity (≥0.90), high-specificity (≥0.90), and Youden-optimal. Secondary analyses included PR/F1, calibration (Brier, slope), and decision curve analysis (DCA). Results: AUC was similar (YOLO-TL 0.954 [95% CI 0.937–0.970] vs. YOLO-SC 0.961 [0.948–0.973]; DeLong p = 0.53). At the high-sensitivity point (both sensitivity = 0.903), YOLO-TL achieved higher specificity (0.903 vs. 0.867; McNemar p = 0.037) and PPV (0.840 vs. 0.793; bootstrap p = 0.030), reducing ~17 false positives among 475 negatives. At the high-specificity point (~0.902–0.903 for both), YOLO-TL showed higher sensitivity (0.798 vs. 0.764; p = 0.0077). At the Youden-optimal point, sensitivity favored YOLO-TL (0.914 vs. 0.892; p = 0.041) with a non-significant specificity difference. Conclusions: Transfer learning may not improve overall AUC but can enhance practical performance at clinically crucial thresholds. By maintaining high detection rates while reducing false positives, the transfer learning model offers superior clinical utility. Same-modality cross-domain transfer learning is an efficient strategy for developing robust AI systems for rare diseases, supporting tools more readily acceptable in real-world screening workflows.

Tomography-Based Navigation System for Total Hip Arthroplasty in Severe Hip Dysplasia: A Simulation Study Using 3D-Printed Bone Models of Crowe Types II, III, and IV en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and Objective: The use of computed tomography (CT)-based navigation systems has been shown to improve surgical accuracy in total hip arthroplasty. However, there is limited literature available about the application of CT-based navigation systems in severe hip dysplasia. This study aimed to evaluate the accuracy of a CT-based navigation system in patients with severe hip dysplasia using three-dimensional (3D)-printed bone models. Methods: 3D-printed bone models were generated from CT data of patients with severe hip dysplasia (Crowe type II, 10 hips; type III, 10 hips; and type IV, 10 hips). The accuracy of automatic segmentation, success rate, point-matching accuracy across different registration methods, and deviation values at reference points after registration were assessed. Results: For the combined cohort of Crowe II, III, and IV cases (n = 30), the Dice Similarity Coefficient and Jaccard Index were 0.99 ± 0.01 and 0.98 ± 0.02, respectively. These values indicate a high level of segmentation accuracy. The “Matching with true and false acetabulum + iliac crest” method achieved a 100% success rate across all groups, with mean deviations of 0.08 ± 0.28 mm in the Crowe II group, 0.12 ± 0.33 mm in the Crowe III group, and 0.14 ± 0.50 mm in the Crowe IV group (p = 0.572). In the Crowe IV group, the anterior superior iliac spine deviation was significantly lower using the “Matching with true and false acetabulum + iliac crest” method compared to the “Matching with true and false acetabulum” method (0.28 ± 0.49 mm vs. 3.29 ± 2.56 mm, p < 0.05). Conclusions: This study demonstrated the high accuracy of automatic AI-based segmentation, with a Dice Similarity Coefficient of 0.99 ± 0.01 and a Jaccard Index of 0.98 ± 0.02 in the combined cohort of Crowe type II, III, and IV cases (n = 30). The matching success rate was 100%, with additional points on the iliac crest, which improved matching accuracy and reduced deviations, depending on the case. en-copyright= kn-copyright= en-aut-name=OkudaRyuichiro en-aut-sei=Okuda en-aut-mei=Ryuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 ORCID= en-aut-name=TetsunagaTomoko en-aut-sei=Tetsunaga en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KouraTakashi en-aut-sei=Koura en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=InoueTomohiro en-aut-sei=Inoue en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MasadaYasutaka en-aut-sei=Masada en-aut-mei=Yasutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=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 Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Musculoskeletal Health Promotion, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Sports Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University 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= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=total hip arthroplasty kn-keyword=total hip arthroplasty en-keyword=CT-based navigation kn-keyword=CT-based navigation en-keyword=bone model kn-keyword=bone model en-keyword=artificial intelligence kn-keyword=artificial intelligence en-keyword=Ortoma Treatment Solution kn-keyword=Ortoma Treatment Solution END start-ver=1.4 cd-journal=joma no-vol=94 cd-vols= no-issue=11 article-no= start-page=3653 end-page=3665 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=Survey of Barley Sodium Transporter HvHKT1;1 Variants and Their Functional Analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Barley (Hordeum vulgare L.) employs the Na+ transporter HvHKT1;1, which is an N+-selective transporter. This study characterized the full-length HvHKT1;1 (HvHKT1;1-FL) and three mRNA variants (HvHKT1;1-V1, -V2, and -V3), which encode polypeptides of 64.7, 54.0, 40.5, and 32.9 kDa, respectively. Tissue-specific expression profiling revealed that HvHKT1;1-FL is the most abundant transcript across leaf, sheath, and root tissues under normal conditions, with the highest expression in leaves. Under 150 mM NaCl stress, HvHKT1;1-FL and its variants showed a dynamic, time-dependent expression pattern, with peak leaf expression at 2 h, sheath expression at 12 h, and root expression at 2 h, suggesting their roles in early stress response. Functional analysis using two-electrode voltage-clamp measurements demonstrated that HvHKT1;1-FL is highly selective for Na+, with minimal conductance for K+, Li+, Rb+, or Cs+. It demonstrated high Na+ transport efficiency, characterized by higher Vmax and lower Km values, while the variants showed reduced Na+ currents, lower Vmax, and higher Km values, indicating decreased Na+ transport capacity. Reversal potential analyses further confirmed Na+ selectivity, with HvHKT1;1-FL displaying the strongest preference for Na+. Notably, while all variants retained Na+ selectivity, they showed reduced efficiency, as indicated by a more negative reversal potential in low Na+ conditions. These findings highlight the functional diversity among HvHKT1;1 variants, with HvHKT1;1-FL playing a dominant role in Na+ transport. The tissue-specific regulation of these variants under salinity stress underscores their importance in barley’s adaptive responses. en-copyright= kn-copyright= en-aut-name=ImranShahin en-aut-sei=Imran en-aut-mei=Shahin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KatsuharaMaki en-aut-sei=Katsuhara en-aut-mei=Maki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=Department of Agronomy, Khulna Agricultural University kn-affil= en-keyword=Barley kn-keyword=Barley en-keyword=HvHKT1;1 kn-keyword=HvHKT1;1 en-keyword=Na+ transport kn-keyword=Na+ transport en-keyword=mRNA variants kn-keyword=mRNA variants en-keyword=TEVC kn-keyword=TEVC END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=4 article-no= start-page=e83089 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250427 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Subcutaneous and Periorbital Emphysema Following a Dental Procedure en-subtitle= kn-subtitle= en-abstract= kn-abstract=Subcutaneous emphysema following dental procedures is rare.

Prompt clinical suspicion and a thorough evaluation of the signs and symptoms, including a detailed clinical history, are crucial for diagnosing subcutaneous emphysema following a dental procedure. en-copyright= kn-copyright= en-aut-name=ObaraTakafumi en-aut-sei=Obara en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=NakatsujiKazuki en-aut-sei=Nakatsuji en-aut-mei=Kazuki 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=YumotoTetsuya en-aut-sei=Yumoto en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 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 Oral and Maxillofacial Reconstructive Surgery, Okayama University Hospital 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= en-keyword=air pressure kn-keyword=air pressure en-keyword=antibiotic prophylaxis kn-keyword=antibiotic prophylaxis en-keyword=dental procedures kn-keyword=dental procedures en-keyword=operative kn-keyword=operative en-keyword=subcutaneous emphysema kn-keyword=subcutaneous emphysema END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=12 article-no= start-page=2351 end-page=2363 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251024 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Multicenter, Prospective, Observational, and Single-Arm Interventional Study of Mirogabalin in Diabetic Peripheral Neuropathic Pain: Rationale and Design of Dia-NeP en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: The exact prevalence of and recent changes in diabetic polyneuropathy (DPN) and diabetic peripheral neuropathic pain (DPNP) in Japan are unclear. The oral gabapentinoid, mirogabalin besylate (mirogabalin), is effective with a good safety profile for DPNP with moderate-to-severe pain (numerical rating scale [NRS] scores ≥ 4). However, clinical evidence for mild pain (NRS scores ≤ 3) is unclear. The Dia-NeP study aims to examine: (1) the prevalences of DPN and DPNP and background factors in patients with type 2 diabetes mellitus (T2DM); and (2) the efficacy and safety of mirogabalin in patients with DPNP, including those with mild pain.
Methods: The Dia-NeP study is a multicenter, prospective study consisting of two parts, a baseline survey and an interventional study, to be conducted from March 2025 to August 2026 in patients with T2DM in Japan. The baseline survey is the observational study investigating the epidemiology of DPN and DPNP, and the interventional study is an exploratory, single-arm, open-label study of 12-week mirogabalin treatment. Of patients with T2DM enrolled in the baseline survey, those diagnosed with DPNP who have an NRS score for pain ≥ 1 will be included in the interventional study. The target sample size is 1000 to 3000 patients for the baseline survey and 100 for the interventional study.
Planned Outcomes: The primary endpoint is the change from baseline in the NRS score at week 12 in the interventional study. The safety endpoint is adverse events. This study will not only show the latest prevalence of DPN and DPNP in Japan, but is also the first study to investigate the efficacy and safety of mirogabalin in patients with DPNP having mild pain, as well as moderate-to-severe pain, and is expected to provide useful evidence for future DPN and DPNP treatment.

To address the need for a reliable in vitro nephrotoxicity testing platform, we developed a screening model using kidney organoids derived from adult rat kidney stem (KS) cells. The organoids were exposed to known nephrotoxicants, including cisplatin and gentamicin, to validate the system. Puberulic acid toxicity was evaluated in both KS cell-derived organoids and wild-type mice. The organoids recapitulated tubular injury induced by known nephrotoxins and showed significant Kim-1 mRNA upregulation. Puberulic acid-treated organoids and mice exhibited morphological features of acute tubular necrosis (ATN), mitochondrial damage, and reduced cytochrome c oxidase subunit IV (COX-IV) expression. Markers of oxidative stress and apoptosis, such as 8-hydroxy-2’-deoxyguanosine (8-OHdG) and cleaved caspase-3, were also elevated. These findings suggest that puberulic acid induces mitochondrial dysfunction and oxidative stress, leading to tubular cell death. Puberulic acid-induced nephrotoxicity was demonstrated using our kidney organoid model. KS cell-derived kidney organoids may provide a simple, reproducible, and rapid platform for nephrotoxicity assessment, which may complement conventional animal experiments. 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=UchidaNaruhiko en-aut-sei=Uchida en-aut-mei=Naruhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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=5 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=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= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Kidney organoid kn-keyword=Kidney organoid en-keyword=Kidney stem cell kn-keyword=Kidney stem cell en-keyword=Puberulic acid kn-keyword=Puberulic acid en-keyword=Nephrotoxicity kn-keyword=Nephrotoxicity en-keyword=Mitochondrial dysfunction kn-keyword=Mitochondrial dysfunction END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=11 article-no= start-page=e13960 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Missing the Target: A Scoping Review of the Use of Percent Weight Loss for Obesity Management en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: To co-create comprehensive targets for obesity management, we need to understand the genesis and current use of percent weight loss targets in research. The goals of our scoping review are to (1) synthesize the literature on percent weight loss targets for adults with obesity and (2) discuss the percent weight loss targets in context with their health benefits.
Methods: We searched Cochrane, MEDLINE, and EMBASE for English language, pharmaceutical, and/or behavioral intervention studies in adults with obesity where the explicit aim of the study was weight reduction defined as a percent of body weight. Reviewers screened citations and extracted data including study characteristics.
Results: From 16,164 abstracts, we included 30 citations which were mostly randomized controlled trials (RCTs) (n = 17) or quasi-experimental studies (n = 12) published between 1992 and 2024. Most of the studies had target weight loss goals between 3% and 10% of body weight (n = 28), while n = 2 had body weight loss goals of 15% or 30%. The proportion of participants who met the percent weight loss target ranged from 5.9% (nutrition only study) to 85% (pharmaceutical study). The studies reported different reasons for targeting a percentage of weight loss such as disease-specific outcomes, reduced risk of disease, or patient-reported outcomes.
Conclusion: Percent weight loss targets were based on similar research and were often not feasible nor sustainable for most participants. The design of these interventions and evaluation of obesity management would benefit from more patient-focused parameters which could help to co-design comprehensive targets for research and practice. en-copyright= kn-copyright= en-aut-name=SherifaliDiana en-aut-sei=Sherifali en-aut-mei=Diana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=RaceyMegan en-aut-sei=Racey en-aut-mei=Megan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Fitzpatrick‐LewisDonna en-aut-sei=Fitzpatrick‐Lewis en-aut-mei=Donna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=GreenwayMichelle en-aut-sei=Greenway en-aut-mei=Michelle kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SockalingamSanjeev en-aut-sei=Sockalingam en-aut-mei=Sanjeev 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= en-aut-name=TeohSoo Huat en-aut-sei=Teoh en-aut-mei=Soo Huat kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=PattonIan en-aut-sei=Patton en-aut-mei=Ian kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MacklinDavid en-aut-sei=Macklin en-aut-mei=David kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=van RossumElizabeth F. C. en-aut-sei=van Rossum en-aut-mei=Elizabeth F. C. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=BusettoLuca en-aut-sei=Busetto en-aut-mei=Luca kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=HornDeborah Bade en-aut-sei=Horn en-aut-mei=Deborah Bade kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=Patricia NeceJ. D. en-aut-sei=Patricia Nece en-aut-mei=J. D. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=LeguedeMorgan Emile Gabriel Salmon en-aut-sei=Leguede en-aut-mei=Morgan Emile Gabriel Salmon kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=PearceNicole en-aut-sei=Pearce en-aut-mei=Nicole kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=Le RouxCarel en-aut-sei=Le Roux en-aut-mei=Carel kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= en-aut-name=ArdJamy en-aut-sei=Ard en-aut-mei=Jamy kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=17 ORCID= en-aut-name=AlbergaAngela S. en-aut-sei=Alberga en-aut-mei=Angela S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=18 ORCID= en-aut-name=KaplanLee en-aut-sei=Kaplan en-aut-mei=Lee kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=19 ORCID= en-aut-name=SharmaArya M. en-aut-sei=Sharma en-aut-mei=Arya M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=20 ORCID= en-aut-name=WhartonSean en-aut-sei=Wharton en-aut-mei=Sean kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=21 ORCID= affil-num=1 en-affil=McMaster Evidence Review and Synthesis Team;

In total, 283 and 279 patients were included in the safety (with SGLT2i, 148; without, 135) and full analysis sets (with SGLT2i; 145; without, 134), respectively. Significant changes in morning home systolic/diastolic blood pressure (SBP/DBP) from baseline to Week 12 were shown in the overall population (mean change: −11.9/−5.2 mmHg, both P < 0.001) and both SGLT2i and non-SGLT2i subgroups (−11.3/−4.8 and −12.5/−5.7 mmHg, respectively, all P < 0.001). Similar findings were observed in bedtime home and office SBP/DBP. The proportions of patients who achieved target home SBP/DBP < 135/85 mmHg were 71.2% (overall population) and 70.5% and 71.9% in the SGLT2i and non-SGLT2i subgroups, respectively. The urine albumin-to-creatinine ratio significantly improved from baseline to Week 12 in the overall population and SGLT2i subgroups (percentage change in geometric mean from baseline: −42.8%, −43.0%, and −42.6%, respectively, all P < 0.001). N-terminal pro-B-type natriuretic peptide levels improved in all groups. The incidence of serum potassium ≥5.5 mEq/L was 2.0% vs 5.2% in the SGLT2i vs non-SGLT2i subgroups. Esaxerenone demonstrated significant BP-lowering effects, and improved renal and cardiovascular parameters, regardless of SGLT2i use. Safety was consistent across groups, with the numerically lower incidence of serum potassium ≥5.5 mEq/L in the SGLT2i subgroup suggesting a potential mitigating effect of SGLT2is on the risk of hyperkalemia. en-copyright= kn-copyright= en-aut-name=MotokiHirohiko en-aut-sei=Motoki en-aut-mei=Hirohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KuwaharaKoichiro en-aut-sei=Kuwahara en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 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=4 ORCID= en-aut-name=KarioKazuomi en-aut-sei=Kario en-aut-mei=Kazuomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KatsuyaTomohiro en-aut-sei=Katsuya en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ShimosawaTatsuo en-aut-sei=Shimosawa en-aut-mei=Tatsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TsujitaKenichi en-aut-sei=Tsujita en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SuzukiShoko en-aut-sei=Suzuki en-aut-mei=Shoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SuedomiTomohiro en-aut-sei=Suedomi en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TaguchiTakashi en-aut-sei=Taguchi en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, Shinshu University School of Medicine kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Shinshu University School of Medicine 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=Division of Cardiovascular Medicine, Department of Medicine, Jichi Medical University School of Medicine kn-affil= affil-num=6 en-affil=Katsuya Clinic kn-affil= affil-num=7 en-affil=Department of Clinical Laboratory, School of Medicine, International University of Health and Welfare kn-affil= affil-num=8 en-affil=Department of Cardiovascular Medicine, Graduate School of Medical Sciences, Kumamoto University kn-affil= affil-num=9 en-affil=Data Intelligence Department, Daiichi Sankyo Co.

The subjects were 16 eighth graders in public special-needs schools. In addition to height and weight, the physical activity survey during school life was measured using a uniaxial accelerometer (Kenz Lifecorder GS 4-second version: LC). 7534 ± 2275 steps/day for boys, 6411 ± 1614 steps/day for girls, and middle and high intensity activity time (MVPA) was 19.3 ± 10.3 minutes/day for boys and 16.7 ± 8.3 minutes/day for girls. These results suggest that eighth graders attending special needs schools are well below the WHO Guidelines for Physical Activity and Sedentary Behavior standard of 60 minutes/day for children and adolescents with disabilities (5-17 years old ) for both boys and girls. en-copyright= kn-copyright= en-aut-name=ADACHIMinoru en-aut-sei=ADACHI en-aut-mei=Minoru kn-aut-name=足立稔 kn-aut-sei=足立

を「身体的な感受や経験を通して創造性教育を担う教員」と定義し,その育成に必要なコンピテンシーを「身体的思考」「空間的思考」「批判的対話」「創造的な態度」とした。そこで本論では,授業における創造性育成の要素として四つ挙げ,創造性に関する先行研究を整理した。その結果,創造性の研究において四つの要素を以下の通り捉えられることを確認した。①身体を通した予期せぬ刺激「想定外」は,身体化された認知や素材との相互作用から生じる新しい思考を促す。②他者との関係性を意識した「場づくり」は,対話や協働を通して創造性を育む。③空間的思考に基づく「可視化」は,視覚情報の統合や変換により創造的イメージを支える。④「チャレンジ」は,自律的意思決定や創造的自信を高め,潜在的創造力の発揮を促す。

本稿では,歌唱における発声について,共鳴の視点から,発声を習得する上での問題点や共鳴に対する課題について検討した。合唱指揮者や指導者等の発声における共鳴の捉え方では,共鳴は,頭蓋骨のすべての共鳴腔,音高と声区,声量,顎の開き,蝶形骨等の骨との密接な関係があり,音色形成との複雑な関連性があることを確認した。次に小中学校の学習指導要領や音楽教科書の発声記述について概観した結果,小中学校を通して,段階的に共鳴について,イメージと生理学的面から児童生徒に学習させていることが示された。教員養成学部に在籍する学生に対する発声の質問紙による実態調査では,共鳴は難しい領域という共通認識があり,特に,発声の自己評価が低めのグループにその傾向が強くみられた。生理学的な理解,イメージ的な表現,実際に生成される声,これら相互の関係を解明する必要がある。

年代後半からは社会減も拡大した。両効果が働いたために,2010 年代後半から人口減少が加速した。(2) 2006 年以降,鏡野町の人口移動はおおむね安定した傾向が見られた。そして,その人口移動は,津山圏との間における集中的かつ均衡した人口移動,近畿地方・岡山圏・関東地方への転出超過,真庭圏・阿新圏からの小規模な転入超過と特徴づけることができる。(3) 2010 年代後半から,鏡野町は岡山圏への転出超過が顕著となり,近畿地方および関東地方への転出もそれに続いた。その結果,鏡野町は社会減が大きくなった。農林業・製造業・商業の停滞や都市部との賃金格差が若年層の流出を促進し,社会減の拡大に繋がった。(4) 人口移動の中心は一貫して20 歳代と30 歳代であった。 en-copyright= kn-copyright= en-aut-name=NOBEMasao

本稿は、小学校の政治学習における主権者教育の一例として、「政策カード」を活用した立候補型の模擬市長選挙プログラムを開発し、その実践を通した教育的意義や課題について明らかにするものである。はじめに、小学校政治学習における模擬選挙の実践例を概観し、立候補型の模擬選挙である長瀬(2021)の実践に注目した。その上で、児童の政策立案の質を高めるための工夫として「政策カード」を用いたエリシテーションを取り入れるプログラムを開発し、小学校6 年生の政治単元で実践した。実践結果から、本プログラムは、児童が政策を立案する側に立って自治体の将来を考えることができるという点や、多様な声を反映させるという政治の難しさを体験的に理解できるという点で意義があったが、政策立案活動の真正性や投票規準の明確化に関して、教師の指導やプログラム自体の改善を進める必要があることが明らかになった。 en-copyright= kn-copyright=

本研究は,産業現場の安全を脅かす潜在的なリスクとしてチームワークの崩壊兆候に着目し,その特徴と高信頼性チーム(HRT)の機能,および組織環境要因との関連を実証的に検討した。安全活動への参加経験を持つ就業者357 名から得られたWeb 調査の回答を分析した。チームワークの崩壊兆候は「協調の失敗」と「修正の失敗」の2 因子に整理され,いずれもHRT 機能の発揮と負の関連を示した。また組織環境要因の安全風土やSafety Organizing は崩壊兆候の抑制に,学習のボトルネック認知はその増加に寄与していた。さらに,HRT 機能は個別よりも複合的に発揮されることで,チームの協働作業の円滑化・安定化に資する可能性が示唆された。 en-copyright= kn-copyright= en-aut-name=MISAWARyo

グローバル化,多様性が拡大する社会では,適切に自己を表現する方法の獲得が重要になるのではなかろうか。本研究では,このアサーティブな自己表現の獲得を促す教育的介入を目指して,3 つのタイプの自己表現(攻撃的な自己表現,非主張的な自己表現,アサーティブな自己表現)を比較して,アサーティブな自己表現の特徴を明らかにすることを目指す。先行研究を参考に,これらの自己表現を区別する指標として,評価への敏感さ,被受容感,視点取得,自尊感情を取り上げた。180 人の大学生を対象に調査を行い,分析を行った結果,アサーティブな自己表現には視点取得と自尊感情が関係していることが示された。他方で被主張的な自己表現は,評価への敏感さと被受容感との関係が見られた。攻撃的な自己表現は,視点取得との負の関係が見られた。これらの結果から,教育現場で児童生徒が適切に自己表現できるように促すためには,子供の存在を認め,自尊感情を高めること,他者の視点を配慮する意識を育てること,そして,周囲の評価を気にし過ぎないように促すことが重要である可能性が示唆された。

of electronic medical records across multiple clinics in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Chronic kidney disease (CKD) is a major public health burden in Japan. Japanese primary care physicians (PCPs) are expected to play an important role in the early diagnosis and management of CKD, but comprehensive data on their role are limited.
Methods This observational study examined data from individuals who underwent tests for CKD diagnosis between January 2017 and September 2023 in the Japan Medical Data Survey (JAMDAS) database of primary care clinics in Japan. The primary outcome was the proportion of individuals with CKD without the registration of a CKD-related disease code. Time to CKD diagnosis and referral were also assessed.
Results Among 1,188,543 eligible individuals who underwent kidney-related laboratory tests, 183,473 (15.4%) met CKD diagnosis criteria according to the Japanese Clinical Practice Guideline for CKD. The mean (± SD) age was 77.4 ± 11.0 years, 57.1% were female, and 71.8% had CKD stage 3a. Over 98% of individuals who met CKD diagnosis criteria did not receive an insurance diagnosis code within 90 days after meeting the criteria. Among referrable individuals, 89.7% did not receive a referral within 90 days of meeting the referral criteria.
Conclusion These results suggest CKD may be underdiagnosed and under-referred in Japanese clinics. Measures should be taken to increase detection and diagnosis according to the Japanese Clinical Practice Guideline for CKD. en-copyright= kn-copyright= 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=1 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=2 ORCID= en-aut-name=NagaoYuji en-aut-sei=Nagao en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IharaKatsuhito en-aut-sei=Ihara en-aut-mei=Katsuhito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Medicine Division, Nippon Boehringer Ingelheim Co., Ltd. kn-affil= affil-num=4 en-affil=Medicine Division, Nippon Boehringer Ingelheim Co., Ltd. kn-affil= en-keyword=Chronic kidney disease kn-keyword=Chronic kidney disease en-keyword=Electronic medical records kn-keyword=Electronic medical records en-keyword=Japan kn-keyword=Japan en-keyword=Primary care physician kn-keyword=Primary care physician en-keyword=Disease code kn-keyword=Disease code END start-ver=1.4 cd-journal=joma no-vol=48 cd-vols= no-issue=9 article-no= start-page=2413 end-page=2426 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=Efficacy and safety of esaxerenone in hypertensive patients with chronic kidney disease, with or without type 2 diabetes mellitus: a pooled analysis of five clinical studies en-subtitle= kn-subtitle= en-abstract= kn-abstract=Effective management of blood pressure (BP) and albuminuria are crucial for suppressing chronic kidney disease (CKD) progression and cardiovascular risks in hypertension. This pooled analysis evaluated the antihypertensive effects, organ-protective effects, and safety of esaxerenone in hypertensive patients with CKD by integrating five clinical studies of esaxerenone. Patients were divided based on type 2 diabetes mellitus (T2DM) status (with or without T2DM) and creatinine-based estimated glomerular filtration rate (eGFRcreat) (30 to <60 and ≥60 mL/min/1.73 m2). Significant changes in morning home BP from baseline at Week 12 were observed in the overall population (mean change −12.8/ − 5.4 mmHg), T2DM subgroups ( − 12.2/ − 4.5 and −14.5/ − 7.8 mmHg), and eGFRcreat subgroups ( − 12.5/ − 4.7 and −14.0/ − 6.9 mmHg) (all P < 0.001). Bedtime home and office BP showed similar tendencies. Urine albumin-to-creatinine ratio significantly improved from baseline at Week 12 in the overall population (mean change: −55.2%), T2DM subgroups ( − 56.5% and −52.0%), and eGFRcreat subgroups ( − 54.6% and −55.4%) (all P < 0.001). N-terminal pro-B-type natriuretic peptide levels significantly decreased in the overall population (percent change: −14.1%) and subgroup without T2DM ( − 25.3%). The incidence of serum potassium ≥5.5 mEq/L was lower in the subgroup with T2DM vs without T2DM (3.1% and 11.3%), potentially related to the use of sodium–glucose cotransporter 2 inhibitors. These findings highlight the sustained BP-lowering effect of esaxerenone throughout the day in hypertensive patients with CKD, irrespective of T2DM status, and its significant reduction in albuminuria. The data support the safety and efficacy of esaxerenone in this patient population, underscoring its potential as a valuable therapeutic option. en-copyright= kn-copyright= 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=1 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=2 ORCID= en-aut-name=MotokiHirohiko en-aut-sei=Motoki en-aut-mei=Hirohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KuwaharaKoichiro en-aut-sei=Kuwahara en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KarioKazuomi en-aut-sei=Kario en-aut-mei=Kazuomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KatsuyaTomohiro en-aut-sei=Katsuya en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ShimosawaTatsuo en-aut-sei=Shimosawa en-aut-mei=Tatsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TsujitaKenichi en-aut-sei=Tsujita en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SuzukiShoko en-aut-sei=Suzuki en-aut-mei=Shoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SuedomiTomohiro en-aut-sei=Suedomi en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TaguchiTakashi en-aut-sei=Taguchi en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 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 Cardiovascular Medicine, Shinshu University School of Medicine kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, Shinshu University School of Medicine kn-affil= affil-num=5 en-affil=Division of Cardiovascular Medicine, Department of Medicine, Jichi Medical University School of Medicine kn-affil= affil-num=6 en-affil=Katsuya Clinic kn-affil= affil-num=7 en-affil=Department of Clinical Laboratory, School of Medicine, International University of Health and Welfare kn-affil= affil-num=8 en-affil=Department of Cardiovascular Medicine, Graduate School of Medical Sciences, Kumamoto University kn-affil= affil-num=9 en-affil=Data Intelligence Department, Daiichi Sankyo Co., Ltd. kn-affil= affil-num=10 en-affil=Primary Medical Science Department, Daiichi Sankyo Co., Ltd. kn-affil= affil-num=11 en-affil=Primary Medical Science Department, Daiichi Sankyo Co., Ltd. kn-affil= en-keyword=albuminuria kn-keyword=albuminuria en-keyword=chronic kidney disease kn-keyword=chronic kidney disease en-keyword=esaxerenone kn-keyword=esaxerenone en-keyword=morning hypertension kn-keyword=morning hypertension en-keyword=type 2 diabetes mellitus kn-keyword=type 2 diabetes mellitus END start-ver=1.4 cd-journal=joma no-vol=30 cd-vols= no-issue=5 article-no= start-page=e70057 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=A Case of IgA Nephropathy With Membranoproliferative Glomerulonephritis-Like Features Miyu Kanazawa, en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 73-year-old man was referred due to the onset of nephrotic-range proteinuria. He had been diagnosed with rheumatoid arthritis 18 years prior and had achieved remission with treatment, including methotrexate and janus kinase (JAK) inhibitor. Although routine follow-ups had not revealed any urinary abnormalities, subsequent tests detected proteinuria and hematuria in the absence of infection or other symptoms. As the urinary abnormalities persisted, with a serum albumin decrease and proteinuria measuring 5.7 g/day, indicating nephrotic syndrome, the patient was referred to our hospital for further evaluation, and a renal biopsy was performed. Light microscopy revealed mesangial cell proliferation, endocapillary proliferation and double-contoured basement membranes. Immunofluorescence microscopy showed IgA-dominant deposits in both mesangial areas and glomerular capillary walls. Transmission electron microscopy demonstrated electron-dense deposits in the mesangium and subendothelial regions, leading to the diagnosis of membranoproliferative glomerulonephritis (MPGN)-type IgA nephropathy. Immunostaining with the Gd-IgA1 (galactose-deficient IgA1)-specific antibody (KM55) was positive, consistent with the diagnosis. Following the initiation of steroid therapy, proteinuria rapidly decreased, achieving complete remission within 5 months. IgA nephropathy with MPGN-like features often presents as nephrotic syndrome, differing from the typical pathological and clinical presentation of IgA nephropathy, making differentiation from secondary MPGN and other diseases sometimes challenging. This case suggests that KM55 staining may offer additional information in differentiating atypical IgA nephropathy with non-classical pathological features. en-copyright= kn-copyright= en-aut-name=KanazawaMiyu en-aut-sei=Kanazawa en-aut-mei=Miyu 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=AokiRyoya en-aut-sei=Aoki en-aut-mei=Ryoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SueMihiro en-aut-sei=Sue en-aut-mei=Mihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyakeHiromasa en-aut-sei=Miyake en-aut-mei=Hiromasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UchidaNaruhiko en-aut-sei=Uchida en-aut-mei=Naruhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakanohHiroyuki en-aut-sei=Nakanoh en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 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=9 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=10 ORCID= affil-num=1 en-affil=Okayama University Medical School kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Okayama University Medical School kn-affil= affil-num=4 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences 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=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Chronic Kidney Disease and Cardiovascular Disease, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Gd-IgA1 kn-keyword=Gd-IgA1 en-keyword=IgA nephropathy kn-keyword=IgA nephropathy en-keyword=membranoproliferative glomerulonephritis kn-keyword=membranoproliferative glomerulonephritis en-keyword=nephrotic syndrome kn-keyword=nephrotic syndrome en-keyword=rheumatoid arthritis kn-keyword=rheumatoid arthritis END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=6 article-no= start-page=1100 end-page=1111 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250327 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Relation between obesity and health disorders as revealed by the J-ORBIT clinical information collection system directly linked to electronic medical records (J-ORBIT 1) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aims/Introduction: Obesity triggers various health disorders, but information on these disorders in real-world settings remains limited. To address this knowledge gap, we developed a database directly linked to electronic medical records (EMRs). We here present the baseline data for this database, designated Japan Obesity Research Based on electronIc healTh Records (J-ORBIT).
Materials and Methods: Individuals with obesity disease diagnosed according to the criteria of the Japan Society for the Study of Obesity were registered in J-ORBIT from seven medical centers in Japan. We analyzed the relationship between body mass index (BMI), clinical characteristics, and the prevalence of obesity-related health disorders in this cohort.
Results: Data were obtained from 1,169 individuals, with a mean (±SD) age of 56.9 ± 15.3 years and a BMI of 31.4 ± 6.1 kg/m2. The prevalence of health disorders varied substantially across BMI categories, with a higher BMI being associated with an increased prevalence of hyperuricemia or gout, obstructive sleep apnea syndrome or obesity hypoventilation syndrome, musculoskeletal disorders, and obesity-related kidney disease, as well as with a higher frequency of both a family history of obesity and of a history of childhood obesity. Among individuals with a BMI of ≥25 kg/m2, the prevalence of hypertension and dyslipidemia did not increase with BMI, whereas that of glucose intolerance decreased with increasing BMI.
Conclusions: The J-ORBIT system, which collects clinical data in real time directly from EMRs, has the potential to provide insight into obesity and its associated health conditions, thereby contributing to improved care of affected individuals. en-copyright= kn-copyright= en-aut-name=NishikageSeiji en-aut-sei=Nishikage en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1

patients en-subtitle= kn-subtitle= en-abstract= kn-abstract=Patients with end-stage renal disease have lower fasting plasma glucose and HbA1c levels, with significantly higher insulin levels. For a long time, it has been believed that this higher insulin level in renal failure is due to decreased insulin clearance caused by reduced renal function. However, here we reported that accumulation of the gut microbiota-derived uremic toxin, phenyl sulfate (PS) in the renal failure, increased insulin secretion from the pancreas by enhanced glucose-stimulated insulin secretion. Other endogenous sulfides compounds which accumulated as in the renal failure also increased glucose-stimulated insulin secretion from β-cell. With RNA-seq analyses and gene knock down, we demonstrated that insulin secretion evoked by PS was mediated by Ddah2. In addition, we also found that PS increased insulin resistance through lncRNA expression and Erk phosphorylation in the adipocytes. To confirm the relationship between PS and glucose metabolism in human, we recruited 2 clinical cohort studies (DKD and CKD) including 462 patients, and found that there was a weak negative correlation between PS and HbA1c. Because these trials did not measure fasting insulin level, we alternatively used the urinary C-peptide/creatinine ratio (UCPCR) as an indicator of insulin resistance. We found that PS may induce insulin resistance in patients with eGFR < 60 mL/min/1.73 m2. These data suggest that the accumulation of uremic toxins modulates glucose metabolism and induced insulin resistance in CKD and DKD patients. Considering HbA1c as a reflection of chronic hyperglycemia and UCPCR as a reflection of chronic hyperinsulinemia, our findings indicate that PS is negatively associated with hyperglycemia independent of CKD, and positively associated with hyperinsulinemia in DKD patients. en-copyright= kn-copyright= en-aut-name=TonguYoshiyasu en-aut-sei=Tongu en-aut-mei=Yoshiyasu kn-aut-name= kn-aut-sei=

en-title= kn-title=A pilot transcriptomic study of a novel multitargeted BRT regimen for anti–MDA5 antibody-positive dermatomyositis: improving survival over conventional therapy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Anti-melanoma differentiation-associated gene 5 antibody-positive dermatomyositis (MDA5-DM) is associated with severe outcomes, primarily due to rapidly progressive interstitial lung disease (RP-ILD), which is often refractory to standard therapies such as calcineurin inhibitors (e.g., tacrolimus) combined with cyclophosphamide (TC-Tx). This study evaluated the efficacy of a novel multitargeted regimen combining baricitinib, rituximab, and tacrolimus (BRT-Tx) in improving survival outcomes for MDA5-DM patients with poor prognostic factors.
Methods: Fourteen MDA5-DM patients with multiple adverse prognostic factors were studied. Seven received the BRT-Tx regimen, and the remaining seven, previously treated with TC-Tx, served as historical controls. Twelve-month survival was assessed. Transcriptome analysis was performed for six patients (BRT=3, TC=3), beginning with cluster analysis to evaluate whether changes in peripheral blood gene expression varied according to treatment or prognosis. Gene ontology analysis characterized expression profiles in survivors and distinguished treatment effects. Alterations in the type I, II, and III interferon signatures were also assessed.
Results: In the TC-Tx group, four of seven patients succumbed to RP-ILD, whereas all seven BRT-Tx patients survived the 12-month observation period. Only one BRT-Tx patient required combined rescue therapies, including plasma exchange, and one case of unexplained limbic encephalitis (LE) occurred. Cytomegalovirus reactivation was observed in both groups (BRT: 5/7; TC: 6/7). Transcriptomic analysis revealed no treatment-specific clustering of differentially expressed genes (DEGs) before and after therapy. However, survivors and nonsurvivors formed distinct clusters, with survivors showing significant posttreatment suppression of B-cell-related gene expression. Moreover, interferon signature scores were significantly lower after treatment in survivors than in nonsurvivors. BRT-Tx effectively suppressed B-cell-mediated immune responses and maintained a low interferon signature, while TC-Tx resulted in nonspecific gene suppression, and in nonsurvivors, an elevated interferon signature was observed.
Conclusion: BRT-Tx has the potential to improve survival in MDA5-DM patients by effectively targeting hyperactive immune pathways. The combination of rituximab and tacrolimus is expected to disrupt B-cell–T-cell interactions and reduce autoantibody production, whereas baricitinib may suppress both IFN and GM-CSF signaling, regulating excessive autoimmunity mediated by cells such as macrophages. Unlike TC-Tx, BRT-Tx avoids cyclophosphamide-associated risks such as infertility and secondary malignancies. Future randomized controlled trials are warranted to validate its efficacy and safety. en-copyright= kn-copyright= en-aut-name=TokunagaMoe en-aut-sei=Tokunaga en-aut-mei=Moe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakaiYu en-aut-sei=Nakai en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SatoYoshiharu en-aut-sei=Sato en-aut-mei=Yoshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HiratsukaMitori en-aut-sei=Hiratsuka en-aut-mei=Mitori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MatsumotoYoshinori en-aut-sei=Matsumoto en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakatsueTakeshi en-aut-sei=Nakatsue en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SaekiTakako en-aut-sei=Saeki en-aut-mei=Takako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UmayaharaTakatsune en-aut-sei=Umayahara en-aut-mei=Takatsune kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= en-aut-name=KoyamaYoshinobu en-aut-sei=Koyama en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=Division of Rheumatology, Center for Autoimmune Diseases, Japanese Red Cross Okayama Hospital kn-affil= affil-num=3 en-affil=DNA Chip Research Inc., Medical Laboratory kn-affil= affil-num=4 en-affil=DNA Chip Research Inc., Medical Laboratory kn-affil= affil-num=5 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Division of Rheumatology and Nephrology, Department of Internal Medicine, Nagaoka Red Cross Hospital kn-affil= affil-num=7 en-affil=Division of Rheumatology and Nephrology, Department of Internal Medicine, Nagaoka Red Cross Hospital kn-affil= affil-num=8 en-affil=Division of Dermatology, Center for Autoimmune Diseases, Japanese Red Cross Okayama Hospital kn-affil= affil-num=9 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Division of Rheumatology, Center for Autoimmune Diseases, Japanese Red Cross Okayama Hospital kn-affil= en-keyword=anti-MDA5 antibody-positive dermatomyositis (MDA5-DM) kn-keyword=anti-MDA5 antibody-positive dermatomyositis (MDA5-DM) en-keyword=JAK inhibitor kn-keyword=JAK inhibitor en-keyword=baricitinib kn-keyword=baricitinib en-keyword=rituximab kn-keyword=rituximab en-keyword=multitargeted treatment kn-keyword=multitargeted treatment en-keyword=IFN signature kn-keyword=IFN signature en-keyword=transcriptome analysis kn-keyword=transcriptome analysis END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=1 article-no= start-page=27481 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241111 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association between proteinuria and mineral metabolism disorders in chronic kidney disease: the Japan chronic kidney disease database extension (J-CKD-DB-Ex) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Chronic kidney disease-mineral and bone disorder (CKD-MBD) are recognized as a systemic disease affecting the prognosis of patients with CKD. Proper management of CKD-MBD is important to improve the prognosis of patients with CKD. Although proteinuria is recognized as a poor prognostic factor in these patients, few reports have examined its association with CKD-MBD. We examined the association between proteinuria and CKD-MBD using data from the Japan Chronic Kidney Disease Database Extension (J-CKD-DB-Ex). Among the patients registered in the J-CKD-DB-Ex, 30,977 with CKD stages G2–G5 who had serum creatinine, albumin, calcium, and phosphate concentrations measured at least once and urinalysis performed were included. The patients were divided into four groups (negative, 1+, 2+, and 3+) according to the degree of proteinuria. The association between proteinuria and CKD-MBD was examined by a logistic regression analysis. In a model adjusted for age, sex, diabetes, and the estimated glomerular filtration rate (eGFR), the odds ratio of the 3 + group compared with the negative group significantly increased to 2.67 (95% confidence interval, 2.29–3.13) for hyperphosphatemia, 2.68 (1.94–3.71) for hypocalcemia, and 1.56 (1.24–1.98) for hypomagnesemia. Proteinuria is associated with hyperphosphatemia, hypocalcemia, and hypomagnesemia in patients with CKD independently of eGFR. en-copyright= kn-copyright= en-aut-name=ShimamotoSho en-aut-sei=Shimamoto

cancer-associated stellate cells via macropinocytosis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Pancreatic ductal adenocarcinoma (PDAC)-associated pancreatic stellate cells (PSCs) promote PDAC tumor progression. Notably, PDAC tumors display enhanced macropinocytosis, resulting in enhanced uptake of extracellular particles, including nutrients and viruses. We previously demonstrated the therapeutic potential of telomerase-specific oncolytic adenoviruses OBP-301 and p53-armed OBP-702 against human PDAC cells. However, it remains unclear whether macropinocytosis promotes the virus sensitivity of PDAC-associated PSCs. Here, we show that PSCs activated by human PDAC cells (Panc-1 and BxPC-3) exhibit enhanced sensitivity to wild-type and oncolytic adenoviruses via enhanced macropinocytosis. The virus sensitivity of PSCs was analyzed for the infectivity, replication, and cytopathic activity of wild-type and oncolytic adenoviruses. PDAC-associated PSCs were more sensitive to wild-type and oncolytic adenoviruses than were control PSCs; this sensitivity was mediated by activation of macropinocytosis. In three-dimensional (3D) culture models, p53-armed OBP-702 decreased the viability of PDAC-associated PSCs more strongly than did non-armed OBP-301, reflecting induction of p53-mediated apoptosis. Co-inoculation of PSCs enhanced the growth of PDAC tumors, an effect that was attenuated by OBP-702-mediated p53 activation in the tumor stroma. Our results suggest that p53-armed oncolytic adenovirus OBP-702 eliminates PDAC-associated PSCs via enhancement of macropinocytosis-mediated virus entry and induction of p53-mediated apoptosis.

Review en-subtitle= kn-subtitle= en-abstract= kn-abstract=The bladder trigone is an anatomically and functionally distinct region within the lower urinary tract (LUT), characterized by a dense network of afferent sensory fibers, specialized urothelial interactions, and prominent mechanotransduction mechanisms. Its intricate neuroarchitecture enables precise detection of bladder filling and coordination of micturition, whereas dysregulation of these pathways contributes to lower urinary tract symptoms (LUTS), including urgency, frequency, and bladder pain. Despite its recognized clinical relevance, the structural and functional basis of trigonal sensory signaling - and its role - remain incompletely understood.
This review synthesizes current evidence on trigonal afferent organization, integrating data from anatomical mapping, receptor profiling, electrophysiological characterization, and translational research. Seminal anatomical observations are combined with recent advances in mechanotransduction and purinergic, peptidergic, and transient receptor potential (TRP) signaling to provide a comprehensive perspective. The trigone exhibits three principal afferent classes: (1) intraepithelial fibers penetrating umbrella cells, marked by P2X purinoceptor 3 (P2X3), transient receptor potential vanilloid 1 (TRPV1), calcitonin gene-related peptide (CGRP), and substance P (SP); (2) subepithelial plexuses surrounding microvasculature, enriched in vasoactive neuropeptides and exhibiting plastic hypertrophy in overactive bladder (OAB) and interstitial cystitis/bladder pain syndrome (IC/BPS); and (3) encapsulated corpuscular endings at the lamina propria-detrusor junction, expressing PIEZO1/2 and acid-sensing ion channels (ASICs) for rapid adaptation. In trigeminal dorsal root ganglion (DRG) neurons, high expression of PIEZO2, P2RX3, and voltage-gated sodium channel, type 1.8 (Nav1.8) was observed, revealing their role as the foundation for multisensory information processing. Functional assays highlight distinct mechanotransductive and chemosensory pathways, with aging, inflammation, and neurotrophic factors driving afferent plasticity underlying abnormal bladder sensation, such as urgency, frequency, and pain. Early clinical trials of P2X3 antagonists and intravesical TRPV1 inhibitors demonstrate promising symptomatic benefits. Collectively, evidence positions the bladder trigone as a critical sensory hub where neuronal, urothelial, and immune signals converge to regulate bladder sensation. Understanding its molecular and structural specialization may inform the development of region-specific neuromodulatory therapies targeting sensory urgency and afferent-driven bladder dysfunction. en-copyright= kn-copyright= en-aut-name=SadahiraTakuya en-aut-sei=Sadahira en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=MitsuiYosuke en-aut-sei=Mitsui en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=WatanabeTomofumi en-aut-sei=Watanabe en-aut-mei=Tomofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 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= en-keyword=bladder trigone kn-keyword=bladder trigone en-keyword=botulinum toxin kn-keyword=botulinum toxin en-keyword=lower urinary tract symptoms kn-keyword=lower urinary tract symptoms en-keyword=sensory afferents kn-keyword=sensory afferents en-keyword=varicosities kn-keyword=varicosities END start-ver=1.4 cd-journal=joma no-vol=32 cd-vols= no-issue=6 article-no= start-page=1839 end-page=1864 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250523 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Beneficial fiscal competition for foreign direct investment: transport infrastructure and economic integration en-subtitle= kn-subtitle= en-abstract= kn-abstract=Fiscal policy competition for a multinational enterprise (MNE) resulting in the same location of firms is widely recognized as harmful owing to losses of the host government’s budget without gains from firms’ behavior. In this study, we provide a plausible explanation why fiscal competition for an MNE keeping firms’ location choices unchanged can be beneficial by incorporating governments’ decisions on public investments in transport infrastructure, such as ports, which reduces the trade costs between two competing countries. Our model divides transport costs into infrastructure-independent and infrastructure-dependent; investments in infrastructure reduce infrastructure-dependent costs. We show that fiscal competition increases countries’ investments in infrastructure under low infrastructure-independent transport costs without affecting firms’ locations. Furthermore, we show that the host country benefits from fiscal competition, although it pays a subsidy to the MNE. Moreover, as investments in infrastructure generate positive spillovers, fiscal competition that improves transport infrastructure benefits non-host countries and improves global welfare. en-copyright= kn-copyright= en-aut-name=MoritaShigeo en-aut-sei=Morita en-aut-mei=Shigeo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkoshiHirofumi en-aut-sei=Okoshi en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Faculty of Economics, Fukuoka University kn-affil= affil-num=2 en-affil=Faculty of Economics, Okayama University kn-affil= en-keyword=Fiscal competition for FDI kn-keyword=Fiscal competition for FDI en-keyword=Public infrastructure kn-keyword=Public infrastructure en-keyword=Transport costs kn-keyword=Transport costs en-keyword=Strategic complement kn-keyword=Strategic complement END start-ver=1.4 cd-journal=joma no-vol=786 cd-vols= no-issue= article-no= start-page=152753 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202510 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Hydrogen-rich gas enhances mitochondrial membrane potential and respiratory function recovery in Caco-2 cells post-ischemia-reperfusion injury en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Ischemia-reperfusion (I/R) injury induces oxidative stress, leading to damage in highly susceptible intestinal tissues. Molecular hydrogen (H2) has shown therapeutic potential in I/R injuries, with our prior research showing its efficacy in improving outcomes in rat intestinal transplantation models. However, its impact on mitochondrial function remain insufficiently understood. This study aims to elucidate how H2 modulates mitochondrial function impaired by I/R injury.
Methods: To assess the effects of H2 on I/R injury, cells were divided into three groups: a control group, a hypoxic group (99 % N2, 1 % O2, without H2 for 3, 6, or 24 h), and a hypoxic-H2 group (99 % H2, 1 % O2, for the same durations). After treatment, cells were reoxygenated under normoxic conditions (21 % O2) for 1, 2, 4, or 6 h. Mitochondrial membrane potential, oxygen consumption, and ATP production were measured. Reactive oxygen species production and apoptotic and metabolic regulators were also assessed.
Results: H2 markedly promoting mitochondrial recovery following I/R injury, by enhancing ATP production, restoring mitochondrial membrane potential, and improving oxygen consumption. It also reduced ROS levels and suppressed pro-apoptotic signaling. Notably, H2 suppressed the expression of HIF1α and PDK1, suggesting that H2 may act upstream of hypoxia-driven signaling pathways. These changes promoted oxidative phosphorylation and overall cellular function during reperfusion.
Conclusions: Our findings reveal that H2 therapy supports mitochondrial function, suppresses ROS, and modulates hypoxia-driven pathways in I/R injury. These insights advance the understanding of H2's potential in addressing I/R injury and provide a foundation for its application in other hypoxia-related conditions. en-copyright= kn-copyright= en-aut-name=SeyaMizuki en-aut-sei=Seya en-aut-mei=Mizuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=MengYing en-aut-sei=Meng en-aut-mei=Ying kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HirayamaTakahiro en-aut-sei=Hirayama en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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=6 ORCID= en-aut-name=YoshinoriKosaki en-aut-sei=Yoshinori en-aut-mei=Kosaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= en-aut-name=WatanabeAkihiro en-aut-sei=Watanabe en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=YamadaTaihei en-aut-sei=Yamada en-aut-mei=Taihei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=11 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=12 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=Biological Process of Aging, Tokyo Metropolitan Institute for Geriatrics and Gerontology 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, Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences 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= affil-num=8 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Emergency, Disaster and Critical Care Medicine, Hyogo Medical University kn-affil= affil-num=10 en-affil=Department of Emergency, Disaster and Critical Care Medicine, Hyogo Medical University 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= affil-num=12 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Intestinal ischemia-reperfusion injury kn-keyword=Intestinal ischemia-reperfusion injury en-keyword=Molecular hydrogen kn-keyword=Molecular hydrogen en-keyword=Hydrogen gas therapy kn-keyword=Hydrogen gas therapy en-keyword=Caco-2 cells kn-keyword=Caco-2 cells en-keyword=Mitochondrial function kn-keyword=Mitochondrial function en-keyword=Hypoxia-inducible factor-1α (HIF1α) kn-keyword=Hypoxia-inducible factor-1α (HIF1α) END start-ver=1.4 cd-journal=joma no-vol=67 cd-vols= no-issue=1 article-no= start-page=e70221 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=Pediatric stroke risk and neurotrauma from roller coasters in amusement parks en-subtitle= kn-subtitle= en-abstract= kn-abstract=Although rare, neurotrauma has been documented as a potential risk of high-speed, high-acceleration amusement park rides such as roller coasters. These attractions generate rapid acceleration, deceleration, sharp turns, and significant gravitational forces, which may stress the central nervous system and cerebrovascular structures. This review analyzed pediatric stroke cases (children 15 years old or younger) linked to roller-coaster rides reported in PubMed and summarized the key mechanisms and clinical features associated with such neurotrauma. Documented complications include internal and vertebral carotid artery dissections, with or without stroke, subdural hemorrhage, intraparenchymal hemorrhage, and post-traumatic migraines. The aim of this review is to alert healthcare providers to the possibility of stroke induced by roller-coaster rides, emphasizing the importance of timely diagnosis and management to prevent adverse outcomes. Key considerations include the recognition of risk factors, public education on potential risks, and strategies for preventing complications in at-risk populations. Although intracranial hemorrhage from roller-coaster rides is rare, individuals with predisposing conditions, such as prior head trauma or vascular abnormalities, should be evaluated carefully when presenting with neurological symptoms after such activities. en-copyright= kn-copyright= en-aut-name=MorikawaTomoki en-aut-sei=Morikawa en-aut-mei=Tomoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 ORCID= en-aut-name=TokiokaKohei en-aut-sei=Tokioka en-aut-mei=Kohei 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=TsukaharaKohei en-aut-sei=Tsukahara en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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= en-keyword=amusement parks kn-keyword=amusement parks en-keyword=brain injuries kn-keyword=brain injuries en-keyword=carotid artery dissection kn-keyword=carotid artery dissection en-keyword=stroke kn-keyword=stroke en-keyword=vertebral artery dissection kn-keyword=vertebral artery dissection 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=20251016 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Enhancing Soil Aggregation and Water Retention by Applying Kaolinite Clay to Post‐Tin‐Mined Land on Belitung Island, Indonesia en-subtitle= kn-subtitle= en-abstract= kn-abstract=Post-mining sandy soils have low water retention, which causes soil particle separation and persistent soil erosion. Although organic matter is commonly used for soil restoration, it is lightweight, washes away during heavy rain, and decomposes under strong sunlight. The high potential for extreme rainfall events in tropical regions poses significant challenges to restoration projects. Therefore, we investigated the impact of kaolinite clay particles on enhancing soil stability in post-mining sandy soils. Soil samples were collected from three sites representing different succession stages of post-mined land (0, 1, and 6 years since mining cessation) and an adjacent natural forest as the reference site on Belitung Island, Indonesia. Soil samples were treated with 1% or 5% kaolinite or left untreated (control) and incubated at 34°C to mimic the local conditions of the study area. The samples were then analyzed to determine the soil aggregate distribution, water holding capacity, and soil erodibility, and SEM imaging was performed to examine the soil particle morphology. The results revealed an increasing trend in the silt-sized aggregate content and a 2%–5% increase in water retention in the 6-year soils relative to the untreated soils. The highest water retention was observed in the 6-year post-mining soil sample. Kaolinite amendment significantly reduced soil erodibility by 40%–50% compared to the untreated soils, even in the early restoration period (0–1 year post-mining). Kaolinite improved soil aggregation and water retention in post-mining sandy soils while reducing soil erodibility—highlighting its potential for accelerating land restoration in mining-affected areas. en-copyright= kn-copyright= en-aut-name=PutraHirmas F. en-aut-sei=Putra en-aut-mei=Hirmas F. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MoriYasushi en-aut-sei=Mori en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=clay kn-keyword=clay en-keyword=kaolinite kn-keyword=kaolinite en-keyword=post-tin- mined soils kn-keyword=post-tin- mined soils en-keyword=soil aggregates kn-keyword=soil aggregates en-keyword=soil restoration kn-keyword=soil restoration en-keyword=water-holding capacity kn-keyword=water-holding capacity END start-ver=1.4 cd-journal=joma no-vol=254 cd-vols= no-issue= article-no= start-page=108998 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=Cellulose nanofibers boost soil water availability, plant growth, and irrigation water use efficiency under deficit irrigation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Under climate change, even previously rainfall-prone areas may experience droughts, and effective strategies are vital for soil conservation. Owing to their cutting-edge water absorption and storage properties, cellulose nanofibers (CNF) are expected to increase soil water availability and help plants resist water stress. However, the role of CNF in improving plant growth and soil water retention under various irrigation regimes is not yet known. We evaluated the effects of CNFs on plant available water (PAW), germination, plant growth, and irrigation water use efficiency (IWUE) under both adequate and deficit irrigation conditions. Plant cultivation experiments were conducted using different CNF dosages (0%, 0.1%, 0.5%, and 1.0%), irrigation levels (I100, I50, and I25), and soil types (sandy and silty loam). The results indicated that CNF significantly increased field capacity (FC) and PAW in both soil types, with PAW in CNF-amended soils increasing by up to 110% and 88% in sandy and silty loam soil, respectively, at 1% CNF dosage. In germination tests, CNF showed no phytotoxicity and supported the germination process during water stress, with enhancements of up to 64% and 163% at I50 and up to 125% and 214% at I25 in germination percentage and germination index, respectively. Plant growth experiments revealed that CNF addition helped plants resist water stress, maintaining plant height and weight close to those under full irrigation, while using 50% less water. IWUE analyses demonstrated that CNF enhanced IWUE, with increases of up to 56% under sufficient watering (I100), 169% under moderate water stress (I50), and 120% under severe water stress (I25), at 1% CNF dosage. These findings highlight the potential of CNF as a multifaceted amendment, offering practical solutions for addressing water scarcity challenges and contributing to more resilient and sustainable agricultural practices. en-copyright= kn-copyright= en-aut-name=NgoAn Thuy en-aut-sei=Ngo en-aut-mei=An Thuy kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NguyenManh Cong en-aut-sei=Nguyen en-aut-mei=Manh Cong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MaedaMorihiro en-aut-sei=Maeda en-aut-mei=Morihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoriYasushi en-aut-sei=Mori en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Nong Lam 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= en-keyword=Cellulose nanofibers kn-keyword=Cellulose nanofibers en-keyword=Available water kn-keyword=Available water en-keyword=Plant growth kn-keyword=Plant growth en-keyword=Irrigation water use efficiency kn-keyword=Irrigation water use efficiency en-keyword=Deficit irrigation kn-keyword=Deficit irrigation en-keyword=Water stress kn-keyword=Water stress END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=2 article-no= start-page=650 end-page=653 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250428 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Successful Transplantation of Multiple Organs from Donor after Helium Asphyxiation: First Case Report in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Helium inhalation has increased, but most cases are either minor injuries or deaths; there have not yet been any reported cases of brain death leading to organ donation. We report a patient who attempted helium inhalation and was declared brain dead and became an organ donor without complications. To the best of our knowledge, this is the first reported case of deceased organ donation following helium asphyxiation in Japan. The patient in cardiac arrest was found with a helium-filled vinyl bag sealed around the neck. During emergency medical transport to the hospital, a spontaneous return of circulation was obtained after 31 minutes of cardiopulmonary resuscitation. Upon hospital arrival, the physical examination revealed dilated pupils with no response to light. Electrocardiography showed widespread ST-segment depression and ST-segment elevation in augmented Vector Right, as well as elevated cardiac enzymes and decreased myocardial contractility. Head computed tomography revealed diffuse cerebral edema and loss of the gray-white matter boundary without signs of air embolism in the cerebral and coronary arteries. Despite comprehensive post-cardiac arrest care with recovery of organ function, brain death was confirmed on day 4 after hospitalization. The family consented to organ donation on the 11th day of hospitalization. The heart, lungs, liver, and two kidneys were successfully transplanted and all organs functioned. All organ grafts were functioning well at the 3-month follow-up. Our case demonstrates that brain death caused by helium inhalation is not a contraindication to organ donation. en-copyright= kn-copyright= en-aut-name=JinnoShunta en-aut-sei=Jinno en-aut-mei=Shunta 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=NojimaTsuyoshi en-aut-sei=Nojima en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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=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= en-aut-name=NakaoAtsunori en-aut-sei=Nakao en-aut-mei=Atsunori 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=brain death kn-keyword=brain death en-keyword=heart arrest kn-keyword=heart arrest en-keyword=helium kn-keyword=helium END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=1 article-no= start-page=185 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251001 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Tattoo-associated toxic shock syndrome: a case report en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Toxic shock syndrome (TSS) is a rare but life-threatening complication occasionally reported after tattooing.
Case presentation: : A 29-year-old Japanese man was admitted to Okayama University Hospital, Okayama, Japan, in early spring 2025, one week after receiving a tattoo on his right shoulder and upper arm in Osaka. He presented with fever, gastrointestinal symptoms, hypotension, and multi-organ failure. Despite a failure to isolate a causative pathogen, he met clinical criteria for TSS. Supportive care and broad-spectrum antibiotics led to full recovery.
Conclusions: TSS can occur after tattooing, even in individuals without apparent immunodeficiency. Pathogenic organisms may be unidentifiable; however, clinical diagnosis should not be delayed, and early therapeutic interventions are essential to improve outcomes. en-copyright= kn-copyright= en-aut-name=KuboTakuya en-aut-sei=Kubo en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=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=IioKoji en-aut-sei=Iio en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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=6 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 Infectious Diseases, Okayama University Hospital kn-affil= affil-num=4 en-affil=Microbiology Division, Clinical Laboratory, Okayama University Hospital 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= en-keyword=Blood culture kn-keyword=Blood culture en-keyword=Critically ill kn-keyword=Critically ill en-keyword=Septic shock kn-keyword=Septic shock en-keyword=Tattooing kn-keyword=Tattooing en-keyword=Toxic shock syndrome kn-keyword=Toxic shock syndrome END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=18 article-no= start-page=1481 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250922 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effect of Oral Peritumoral Tissue on Infiltration and Differentiation of Tumor-Associated Macrophages in Oral Squamous Cell Carcinoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=The recruitment of tumor-associated macrophages (TAMs) in the tumor microenvironment (TME) of oral squamous carcinoma (OSCC) affects significant cancer invasion; however, in the normal host tissue that is located in the cancer’s surrounding area, this is poorly investigated. In this study, we examined the impact of gingival connective tissue cells (GCTCs) and periodontal ligament cells (PDLCs), which are involved in the invasive pathway of OSCC, on oral cancer invasion via TAMs recruitment. Transwell (migration) assays were used to examine the effects of GCTCs and PDLCs on the migration of macrophages, which indicated that the interaction between GCTCs and HSC-2/HSC-3 (human oral squamous cell carcinoma cell line) promoted the recruitment of macrophages, whereas the interaction between PDLCs was inhibited. An indirect co-culture was then used to examine the effects of GCTCs and PDLCs on the differentiation of macrophages, which indicated that the interaction between GCTCs enhanced their ability to transform into M2-type macrophages. Furthermore, the effects of GCTCs and PDLCs on the recruitment of CD45(+) monocytes, F4/80(+) M0 macrophages, iNOS(+) M1 macrophages, and CD163(+) M2 TAMs were assayed by immunohistochemistry. The results revealed that the interaction between GCTCs and HSC-2/HSC-3 promoted the infiltration of CD45(+) monocytes, F4/80(+) M0 macrophages, and CD163(+) M2 TAMs, whereas the PDLCs inhibited it, while their effect on iNOS(+) M1 macrophages was limited. Collectively, the GCTCs contributed to the infiltration of TAMs into the TME of OSCC cells, whereas the PDLCs exerted an inhibitory effect. These findings suggest a potential regulatory mechanism underlying the progression of OSCC. en-copyright= kn-copyright= en-aut-name=PiaoTianyan en-aut-sei=Piao en-aut-mei=Tianyan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakabatakeKiyofumi en-aut-sei=Takabatake en-aut-mei=Kiyofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=ZhaoYulu en-aut-sei=Zhao en-aut-mei=Yulu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=EainHtoo Shwe en-aut-sei=Eain en-aut-mei=Htoo Shwe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SoeYamin en-aut-sei=Soe en-aut-mei=Yamin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MinZin Zin en-aut-sei=Min en-aut-mei=Zin Zin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 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=10 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 Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University 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= en-keyword=oral squamous cell carcinoma (OSCC) kn-keyword=oral squamous cell carcinoma (OSCC) en-keyword=gingival connective tissue cells (GCTCs) kn-keyword=gingival connective tissue cells (GCTCs) en-keyword=periodontal ligament cells (PDLCs) kn-keyword=periodontal ligament cells (PDLCs) en-keyword=tumor-associated macrophages (TAMs) kn-keyword=tumor-associated macrophages (TAMs) en-keyword=macrophage polarity kn-keyword=macrophage polarity en-keyword=tumor microenvironment (TME) kn-keyword=tumor microenvironment (TME) END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=17 article-no= start-page=2770 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250825 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Refining the Role of Tumor-Associated Macrophages in Oral Squamous Cell Carcinoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=In the tumor microenvironment, various immune and stromal cells, such as fibroblasts and vascular endothelial cells, contribute to tumor growth and progression by interacting with cancer cells. Tumor-associated macrophages (TAMs) have attracted attention as major players in the tumor microenvironment. The origin of TAMs is believed to be the infiltration of monocytes derived from bone marrow progenitor cells into tumor tissues and their differentiation into macrophages, whereas tissue-resident macrophages derived from yolk sacs have recently been reported. TAMs infiltrating tumor tissues act in a tumor-promoting manner through immunosuppression, angiogenesis, and the promotion of cancer cell invasion. Reflecting the nature of TAMs, increased TAM invasion and TAM-specific gene expression in tumor tissues may be the new biomarkers for cancer. Moreover, new therapeutic strategies targeting TAMs, such as transformation into immunostimulatory macrophages, suppression of TAM infiltration, and promotion of phagocytosis, are being investigated, and many clinical trials are underway. As the origin and function of TAMs are further elucidated, TAM-targeted therapy is expected to become a new option for the immunotherapy of various cancers, including oral cancers. 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=TianyanPiao en-aut-sei=Tianyan en-aut-mei=Piao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=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=KawaiHotaka en-aut-sei=Kawai en-aut-mei=Hotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=EainHtoo Shwe en-aut-sei=Eain en-aut-mei=Htoo Shwe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SoeYamin en-aut-sei=Soe en-aut-mei=Yamin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MinZin Zin en-aut-sei=Min en-aut-mei=Zin Zin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FujiiMasae en-aut-sei=Fujii en-aut-mei=Masae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=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 Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University 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=tumor-associated macrophage (TAM) kn-keyword=tumor-associated macrophage (TAM) en-keyword=oral squamous cell carcinoma (OSCC) kn-keyword=oral squamous cell carcinoma (OSCC) en-keyword=macrophage polarity kn-keyword=macrophage polarity en-keyword=invasion kn-keyword=invasion en-keyword=carcinogenesis kn-keyword=carcinogenesis END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=14 article-no= start-page=4055 end-page=4070 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250922 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=CXCR4 Inhibition Induces Tumor Necrosis by Selectively Targeting the Proliferating Blood Vessels in Oral Squamous Cell Carcinoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=The C-X-C chemokine receptor type 4 (CXCR4) is a G protein-coupled transmembrane receptor that contributes to tumor growth and angiogenesis. While prior studies have primarily focused on CXCR4 expression in cancer cells and its role in metastasis, a few have examined its involvement in tumor-associated vasculature. In this study, we reported for the first time that CXCR4 expression within the tumor vasculature is significantly associated with higher pathological grades of human oral squamous cell carcinoma (OSCC) (p<0.03). A previous study reported that inhibiting CXCR4 with AMD3100 induces tumor cell death and enhances the efficacy of the chemotherapeutic agent cisplatin. These findings suggest that CXCR4 is an important target for cancer treatment. However, the tumor vascular system is known to be heterogeneous within the tumor microenvironment (TME), which may influence the treatment outcomes. Therefore, this study aimed to explore the effect of CXCR4 antagonism on various blood vessels present within the oral squamous cell carcinoma (OSCC) tumor stroma. Although the efficiency of AMD3100 was not significant in MOC cancer cells, necrosis was induced in the TME when applied to a poorly differentiated OSCC model, highlighting the role of the TME. Notably, CXCR4 is found to be highly overlapped with CD105+ angiogenic tumor vessels among various vascular markers. Treatment with AMD3100 leads to a marked reduction in the CD105+ vessels and impairs the maturation of tumor micro-vessels, explaining the cause of observed necrosis. Thus, CXCR4 serves as a promising biomarker in OSCC, and its inhibition with AMD3100 offers the therapeutic potential, particularly in cases with advanced pathological grades. en-copyright= kn-copyright= en-aut-name=SoeYamin en-aut-sei=Soe en-aut-mei=Yamin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=EainHtoo Shwe en-aut-sei=Eain en-aut-mei=Htoo Shwe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YoshidaSaori en-aut-sei=Yoshida en-aut-mei=Saori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OoMay Wathone en-aut-sei=Oo en-aut-mei=May Wathone kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MinZin Zin en-aut-sei=Min en-aut-mei=Zin Zin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakabatakeKiyofumi en-aut-sei=Takabatake en-aut-mei=Kiyofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 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=9 ORCID= affil-num=1 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Science, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Science, Okayama University kn-affil= affil-num=4 en-affil=Preliminary Examination Room, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Pathophysiology and Drug Discovery, Graduate School of Medicine, Dentistry and Pharmaceutical Science, Okayama University kn-affil= affil-num=6 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Science, Okayama University kn-affil= affil-num=7 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Science, Okayama University kn-affil= affil-num=8 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Science, Okayama University kn-affil= affil-num=9 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Science, Okayama University kn-affil= en-keyword=CXCR4 kn-keyword=CXCR4 en-keyword=tumor angiogenesis kn-keyword=tumor angiogenesis en-keyword=chemokine receptors kn-keyword=chemokine receptors en-keyword=tumor microenvironment kn-keyword=tumor microenvironment en-keyword=oral squamous cell carcinoma (OSCC) kn-keyword=oral squamous cell carcinoma (OSCC) en-keyword=AMD3100 kn-keyword=AMD3100 END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue= article-no= start-page=106656 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=Voxel-based method for predicting workpiece chipping in end milling of unsintered pure iron-powder compact en-subtitle= kn-subtitle= en-abstract= kn-abstract=The miniaturization and high-torque requirements of electric motors in automotive and industrial applications have increased the adoption of axial-gap motors that employ unsintered pure iron-powder compacts. However, machining these brittle materials, particularly through end milling, typically results in significant workpiece chipping, which impedes cost-effective prototyping and small-lot production. Conventional chipping-prediction approaches, such as finite-element analysis and critical uncut chip-thickness methods, are limited by their computational costs and prediction accuracy, respectively. This study proposes a novel method for predicting chipping regions in the end milling of pure iron-powder compacts via voxel-based cutting-force simulation. The chipping risk at each voxel was evaluated based on the magnitude and direction of the simulated cutting force and local workpiece rigidity. Chipping was predicted when the risk index exceeded the threshold value. Cutting experiments were conducted to validate the proposed method, which shows good agreement between the predicted and observed chipping regions under various milling conditions. The results indicate that the proposed method can efficiently and accurately predict the chipping regions, thus outperforming conventional approaches in terms of computational cost. Although parameter tuning and threshold calibration were performed experimentally, the voxel-based framework enables practical prediction and analysis of transient machining phenomena. Future investigations shall focus on expanding the method to a wider range of machining conditions and integrating material-property considerations for further generalization. This approach offers a practical tool for optimizing machining parameters to minimize chipping and enhance the manufacturability of brittle powder compacts. en-copyright= kn-copyright= en-aut-name=TakayasuHiroto en-aut-sei=Takayasu en-aut-mei=Hiroto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KanekoKazuki en-aut-sei=Kaneko en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShimizuJun en-aut-sei=Shimizu en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Science and Engineering, Ibaraki University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Science and Engineering, Ibaraki University kn-affil= en-keyword=End milling kn-keyword=End milling en-keyword=Simulation kn-keyword=Simulation en-keyword=Voxel model kn-keyword=Voxel model en-keyword=Workpiece chipping kn-keyword=Workpiece chipping en-keyword=Brittle material kn-keyword=Brittle material en-keyword=Pure iron-powder compact kn-keyword=Pure iron-powder compact END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=e64296 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251106 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Giant Choledochal Cyst in a Child With Spinocerebellar Ataxia: A Potential Molecular Link Through Aberrant Cytosolic Calcium Signaling en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=SumitomoHiromi en-aut-sei=Sumitomo en-aut-mei=Hiromi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AkiyamaTomoyuki en-aut-sei=Akiyama en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanameTadashi en-aut-sei=Kaname en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakenouchiToshiki en-aut-sei=Takenouchi en-aut-mei=Toshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Pediatric Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pediatric Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Genome Medicine, National Center for Child Health and Development kn-affil= affil-num=4 en-affil=Department of Pediatric Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=calcium signaling kn-keyword=calcium signaling en-keyword=cerebellar ataxia 29 kn-keyword=cerebellar ataxia 29 en-keyword=cerebellar atrophy kn-keyword=cerebellar atrophy en-keyword=choledochal cyst kn-keyword=choledochal cyst en-keyword=congenital biliary dilatation kn-keyword=congenital biliary dilatation en-keyword=inositol 1,4,5-trisphosphate receptors kn-keyword=inositol 1,4,5-trisphosphate receptors en-keyword=ITPR1 kn-keyword=ITPR1 END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=3 article-no= start-page=965 end-page=970 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Decreased homovanillic acid and 5‐hydroxyindoleacetic acid levels in the cerebrospinal fluid of patients with Dravet syndrome with parkinsonism en-subtitle= kn-subtitle= en-abstract= kn-abstract=Dravet syndrome (DS) is an early onset, developmental, and epileptic encephalopathy characterized by drug-resistant seizures and multiple comorbidities. It has been reported that in adulthood, it may be accompanied by parkinsonism, but the pathogenesis of this condition remains unclear. We performed dopamine transporter single-photon emission computed tomography (DAT SPECT) and measured monoamine metabolite levels in the cerebrospinal fluid (CSF) in two adult patients with DS who developed parkinsonism around the age of 30 years. DAT SPECT showed no abnormalities in either patient, whereas CSF tests revealed significant decreases in the levels of homovanillic and 5-hydroxyindoleacetic acids. One patient with severe symptoms was treated with levodopa–carbidopa, which improved parkinsonism manifestations. The other patient initiated treatment with a low dose and has been continuing the treatment without any reported side effects. In conclusion, CSF testing can detect a decrease in dopamine synthesis and may be useful in monitoring the efficacy of levodopa treatment in patients with DS and parkinsonism.
Plain Language Summary: Dravet syndrome (DS) is an early onset, developmental, and epileptic encephalopathy. DS can lead to the development of parkinsonism in adulthood, a clinical syndrome characterized by tremor, slowed movements, and rigidity. Although parkinsonism is a significant issue for patients, its underlying pathology has not yet been elucidated. In this study, we confirmed that the levels of monoamine metabolites in the CSF were low in two patients, potentially shedding light on the pathology involved. en-copyright= kn-copyright= en-aut-name=SugiyamaRyo en-aut-sei=Sugiyama en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SaitoTakashi en-aut-sei=Saito en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KatsumotoAtsuko en-aut-sei=Katsumoto en-aut-mei=Atsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YonenoShota en-aut-sei=Yoneno en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AkiyamaTomoyuki en-aut-sei=Akiyama en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KomakiHirofumi en-aut-sei=Komaki en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Child Neurology, National Center Hospital, National Center of Neurology and Psychiatry kn-affil= affil-num=2 en-affil=Department of Child Neurology, National Center Hospital, National Center of Neurology and Psychiatry kn-affil= affil-num=3 en-affil=Department of Neurology, National Center Hospital, National Center of Neurology and Psychiatry kn-affil= affil-num=4 en-affil=Department of Child Neurology, National Center Hospital, National Center of Neurology and Psychiatry kn-affil= affil-num=5 en-affil=Department of Pediatric Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences and Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Child Neurology, National Center Hospital, National Center of Neurology and Psychiatry kn-affil= en-keyword=dopamine transporter kn-keyword=dopamine transporter en-keyword=levodopa kn-keyword=levodopa en-keyword=monoamine metabolites kn-keyword=monoamine metabolites en-keyword=single-photon emission computed tomography kn-keyword=single-photon emission computed tomography END start-ver=1.4 cd-journal=joma no-vol=2025 cd-vols= no-issue=1 article-no= start-page=e240121 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250127 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Adult hypophosphatasia presenting with recurrent acute joint pain en-subtitle= kn-subtitle= en-abstract= kn-abstract=Hypophosphatasia (HPP) is a genetic disorder due to pathological variants in ALPL, the gene encoding tissue-nonspecific alkaline phosphatase (ALP). HPP is typically associated with bone-related symptoms, such as bone deformity, fractures and bone pain in children, but can appear in adults with symptoms resembling arthritis. A 22-year-old male experienced repeated and severe sudden attacks of joint pain in the elbows and knees. Magnetic resonance imaging and joint ultrasonography showed joint effusions indicating chronic inflammation. Blood biochemical tests revealed a remarkably low serum ALP level, and repeated examination confirmed a sustained low ALP level; urine phosphoethanolamine, plasma inorganic pyrophosphate and plasma pyridoxal-5′-phosphate levels were elevated, raising concern for HPP. While the patient had no history of premature loss of primary teeth, fragility fractures, muscle weakness or abnormalities in growth, genetic testing revealed a likely pathogenic and a pathogenic heterozygous variant in the ALPL gene, i.e., c.979T>C (p.Phe327Leu) and c.1559del (p.Leu520Argfs), confirming HPP. Additional genetic testing of his parents showed a heterozygous c.1559del variant in his father and a heterozygous c.979T>C variant in his mother. A diagnosis of adult HPP due to compound heterozygous mutations was therefore confirmed. Enzyme replacement therapy with asfotase alfa was then introduced; no attacks of arthralgia occurred in the 1-year period since then. This case highlights the possibility of HPP in adults who present clinically with repeated joint symptoms and low serum ALP levels but without bone-related symptoms. en-copyright= kn-copyright= en-aut-name=YoshidaHayao en-aut-sei=Yoshida en-aut-mei=Hayao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MurakamiTakaaki en-aut-sei=Murakami en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OgawaAtsubumi en-aut-sei=Ogawa en-aut-mei=Atsubumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SunouchiTakashi en-aut-sei=Sunouchi en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HidakaNaoko en-aut-sei=Hidaka en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ItoNobuaki en-aut-sei=Ito en-aut-mei=Nobuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MurakamiHiromi en-aut-sei=Murakami en-aut-mei=Hiromi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KawasakiHidenori en-aut-sei=Kawasaki en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=AkiyamaTomoyuki en-aut-sei=Akiyama en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NakajimaKatsumi en-aut-sei=Nakajima en-aut-mei=Katsumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YabeDaisuke en-aut-sei=Yabe en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=YamamotoTaizo en-aut-sei=Yamamoto en-aut-mei=Taizo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Diabetes and Endocrinology, Shiga General Hospital kn-affil= affil-num=2 en-affil=Department of Diabetes and Endocrinology, Shiga General Hospital kn-affil= affil-num=3 en-affil=Department of Rheumatology and Clinical Immunology, Kyoto University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Division of Nephrology and Endocrinology, The University of Tokyo Hospital kn-affil= affil-num=5 en-affil=Division of Nephrology and Endocrinology, The University of Tokyo Hospital kn-affil= affil-num=6 en-affil=Osteoporosis Center, The University of Tokyo Hospital kn-affil= affil-num=7 en-affil=Department of Genomic Medicine, Kyoto University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of Genomic Medicine, Kyoto University Graduate School of Medicine kn-affil= affil-num=9 en-affil=Department of Child Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Diabetes and Endocrinology, Shiga General Hospital kn-affil= affil-num=11 en-affil=Department of Diabetes, Endocrinology and Nutrition, Kyoto University Graduate School of Medicine kn-affil= affil-num=12 en-affil=Department of Diabetes and Endocrinology, Shiga General Hospital kn-affil= en-keyword=hypophosphatasia kn-keyword=hypophosphatasia en-keyword=genetic disorders kn-keyword=genetic disorders en-keyword=bone kn-keyword=bone END start-ver=1.4 cd-journal=joma no-vol=122 cd-vols= no-issue=5 article-no= start-page=689 end-page=699 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=Cytomegalovirus reactivation in patients with large B-cell lymphoma treated with chimeric antigen receptor T-cell therapy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Chimeric antigen receptor (CAR) T-cell therapy has improved outcomes of relapsed and/or refractory large B-cell lymphoma (r/r LBCL). However, its off-tumor effects result in severe prolonged humoral immune deficiency. Cytomegalovirus (CMV) is a latent virus that can be life-threatening in immunosuppressed patients. In the setting of CAR T-cell therapy, Asian race is a risk factor for clinically significant CMV infection. However, the effect of CAR T-cell therapy on CMV reactivation in Japanese patients remains unclear. Previous reports used polymerase chain reaction (PCR), but we used the pp65 antigenemia assay to retrospectively investigate long-term effects in patients with r/r LBCL. The study included 46 patients. Nine (19.6%) developed CMV reactivation, with a median onset of 13 days. Six of these patients received preemptive therapy, and none developed CMV end-organ disease. Primary refractory disease, grade 2–4 cytokine release syndrome, and high-dose corticosteroids were risk factors for CMV reactivation. Long-term follow-up showed that CMV reactivation rarely occurred later than 28 days post-infusion. Our study using the pp65 antigenemia assay showed a similar incidence of CMV reactivation, onset, and risk factors to those in the previous reports using PCR. 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=SeikeKeisuke en-aut-sei=Seike en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MasunariTaro en-aut-sei=Masunari en-aut-mei=Taro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HashidaRisa en-aut-sei=Hashida en-aut-mei=Risa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkaSatoshi en-aut-sei=Oka en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujiwaraYuki en-aut-sei=Fujiwara en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 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=8 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=9 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=10 ORCID= en-aut-name=KondoTakumi en-aut-sei=Kondo en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 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=12 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=13 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=14 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=15 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=16 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=17 ORCID= affil-num=1 en-affil=Department of Hematology and Oncology, Okayama University kn-affil= affil-num=2 en-affil=Department of Hematology and Oncology, Okayama University kn-affil= affil-num=3 en-affil=Department of Hematology, Chugoku Central Hospital kn-affil= affil-num=4 en-affil=Division of Hematology, Ehime Prefectural Central Hospital kn-affil= affil-num=5 en-affil=Department of Hematology and Blood Transfusion, Kochi Health Science Center kn-affil= affil-num=6 en-affil=Department of Hematology and Oncology, Japanese Red Cross Society Himeji Hospital kn-affil= affil-num=7 en-affil=Department of Hematology and Oncology, Okayama University kn-affil= affil-num=8 en-affil=Department of Hematology and Oncology, Okayama University kn-affil= affil-num=9 en-affil=Department of Hematology and Oncology, Okayama University kn-affil= affil-num=10 en-affil=Department of Hematology and Oncology, Okayama University kn-affil= affil-num=11 en-affil=Department of Hematology and Oncology, Okayama University kn-affil= affil-num=12 en-affil=Department of Hematology and Oncology, Okayama University kn-affil= affil-num=13 en-affil=Department of Hematology and Oncology, Okayama University kn-affil= affil-num=14 en-affil=Department of Hematology and Oncology, Okayama University kn-affil= affil-num=15 en-affil=Department of Hematology and Oncology, Okayama University kn-affil= affil-num=16 en-affil=Department of Hematology and Oncology, Okayama University kn-affil= affil-num=17 en-affil=Department of Hematology and Oncology, Okayama University kn-affil= en-keyword=Cytomegalovirus reactivation kn-keyword=Cytomegalovirus reactivation en-keyword=Large B-cell lymphoma kn-keyword=Large B-cell lymphoma en-keyword=CAR T-cell therapy kn-keyword=CAR T-cell therapy en-keyword=Hypogammaglobulinemia kn-keyword=Hypogammaglobulinemia 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=20251019 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Impact of methotrexate-dosing regimens for GVHD prophylaxis on clinical outcomes of HLA-matched allogeneic HSCT en-subtitle= kn-subtitle= en-abstract= kn-abstract=Severe graft-versus-host disease (GVHD) remains a major complication of allogeneic haematopoietic stem cell transplantation (allo-HSCT), necessitating optimal immunosuppressive strategies. This retrospective study used data from the Japanese Transplant Registry Unified Management Program to compare three methotrexate (MTX)-dosing regimens for GVHD prophylaxis in patients undergoing human leucocyte antigen (HLA)-matched allo-HSCT: a low-dose 3-day regimen (Ld3:10 mg/m2 on day 1, 7 mg/m2 on days 3 and 6), a low-dose 4-day regimen (Ld4: Ld3 with an additional 7 mg/m2 on day 11) and an original-dose 3-day regimen (Od3: 15 mg/m2 on day 1, 10 mg/m2 on days 3 and 6). Among 2537 analysed patients, Ld3 was the most commonly used regimen. Multivariate analyses showed no significant differences in the cumulative incidence of grade II–IV acute GVHD among regimens. However, Od3 was associated with an increased risk of grade III–IV acute GVHD, and Ld4 was linked to delayed neutrophil engraftment. This study is the first large-scale retrospective analysis of the impact of different MTX-dosing regimens on the outcomes of HLA-matched allo-HSCT, providing valuable insights into optimal MTX-dosing strategies in clinical practice. en-copyright= kn-copyright= en-aut-name=SuzukiTomotaka en-aut-sei=Suzuki en-aut-mei=Tomotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID=

kn-abstract=Introduction: Invasive fungal infection (IFI) after chimeric antigen receptor (CAR) T-cell therapy is less common than bacterial and viral infections, but can be fatal once it develops. As most cases occur within 30 days after CAR T-cell infusion, late-onset IFI—particularly mould infection—appears to be under-recognised.
Discussion: We report an illustrative case of pituitary aspergillosis developing as late as one year after CD19 CAR T-cell therapy, highlighting a persistent risk in certain patients with delayed immune reconstitution.
Conclusion: This case underscores the need for continued vigilance and individualised antifungal strategies to prevent IFI beyond the early post-infusion period.

Because PR includes heterogeneous clinical presentations, reclassifying PR could produce a better end point. Patients in the primary treatment cohort from the Japanese Society for Transplantation and Cellular Therapy (JSTCT) were randomly divided into training and validation sets. In the training set, a classification and regression tree algorithm generated day 28 refined response (RR) criteria based on symptoms at treatment and day 28. We then evaluated RR for primary and second-line treatments, using the area under the receiver operating characteristic curve (AUC) and negative predictive value (NPV) for 6-month nonrelapse mortality as performance measures. RR considered patients with grade 0/1 at day 28 without additional treatment as responders. RR for primary treatment produced higher AUCs than OR with small improvement of NPVs in both validation sets: JSTCT (AUC, 0.73 vs 0.69 [P < .001]; NPV, 92.0% vs 89.6% [P < .001]) and the Mount Sinai Acute GVHD International Consortium (MAGIC; AUC, 0.71 vs 0.68 [P = .032]; NPV, 90.9% vs 89.8% [P = .009]). RR for second-line treatment produced similar AUCs but much higher NPVs than OR in both validation sets of JSTCT (AUC, 0.64 vs 0.63 [P = .775]; NPV, 74.5% vs 66.0% [P < .001]) and MAGIC (AUC, 0.67 vs 0.64 [P = .105]; NPV, 86.8% vs 76.1% [P = .004]). Classifying persistent but mild skin symptoms as responses and residual lower gastrointestinal GVHD as nonresponses were major drivers in improving the prognostic performance of RR. Our externally validated day 28 RR would serve as a better end point than conventional criteria in future first- and second-line treatment trials. en-copyright= kn-copyright= en-aut-name=AkahoshiYu en-aut-sei=Akahoshi en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=InamotoYoshihiro en-aut-sei=Inamoto en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SpyrouNikolaos en-aut-sei=Spyrou en-aut-mei=Nikolaos kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakasoneHideki en-aut-sei=Nakasone en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=DinizMarcio A. en-aut-sei=Diniz en-aut-mei=Marcio A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=AyukFrancis en-aut-sei=Ayuk en-aut-mei=Francis kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ChoeHannah K. en-aut-sei=Choe en-aut-mei=Hannah K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=DokiNoriko en-aut-sei=Doki en-aut-mei=Noriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=EtoTetsuya en-aut-sei=Eto en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=EtraAaron M. en-aut-sei=Etra en-aut-mei=Aaron M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=HexnerElizabeth O. en-aut-sei=Hexner en-aut-mei=Elizabeth O. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=HiramotoNobuhiro en-aut-sei=Hiramoto en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=HoganWilliam J. en-aut-sei=Hogan en-aut-mei=William J. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=HollerErnst en-aut-sei=Holler en-aut-mei=Ernst kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=KataokaKeisuke en-aut-sei=Kataoka en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= en-aut-name=KawakitaToshiro en-aut-sei=Kawakita en-aut-mei=Toshiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=17 ORCID= en-aut-name=TanakaMasatsugu en-aut-sei=Tanaka en-aut-mei=Masatsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=18 ORCID= en-aut-name=TanakaTakashi en-aut-sei=Tanaka en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=19 ORCID= en-aut-name=UchidaNaoyuki en-aut-sei=Uchida en-aut-mei=Naoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=20 ORCID= en-aut-name=VasovaIngrid en-aut-sei=Vasova en-aut-mei=Ingrid kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=21 ORCID= en-aut-name=YoshiharaSatoshi en-aut-sei=Yoshihara en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=22 ORCID= en-aut-name=IshimaruFumihiko en-aut-sei=Ishimaru en-aut-mei=Fumihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=23 ORCID= en-aut-name=FukudaTakahiro en-aut-sei=Fukuda en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=24 ORCID= en-aut-name=ChenYi-Bin en-aut-sei=Chen en-aut-mei=Yi-Bin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=25 ORCID= en-aut-name=KandaJunya en-aut-sei=Kanda en-aut-mei=Junya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=26 ORCID= en-aut-name=NakamuraRyotaro en-aut-sei=Nakamura en-aut-mei=Ryotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=27 ORCID= en-aut-name=AtsutaYoshiko en-aut-sei=Atsuta en-aut-mei=Yoshiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=28 ORCID= en-aut-name=FerraraJames L.

We conducted a prospective trial in patients with TI-NSAA treated with CsA monotherapy. CsA (3.5 mg/kg/day) was administered to patients with TI-NSAA aged ≥16. The CsA dose was adjusted to maintain a blood CsA level of ≥600 ng/mL at 2 h post-administration. Blood cell counts were assessed after 8, 16 and 52 weeks of therapy. Thirty-two evaluable patients from 21 institutions were enrolled. The median age was 63.5 (range: 16–83) years. At 8 weeks, haematological improvement, with increases in haemoglobin (Hb) ≥1.5 g/dL (haematological improvement in erythrocytes [HI-E]) and platelet count ≥30 × 109/L (haematological improvement in platelets [HI-P]), was observed in 0/25 (0%) and 6/32 (19%) evaluable cases respectively. HI-E and HI-P occurred in 1/25 (4%) and 10/32 (31%) patients at 16 weeks, respectively, and at 52 weeks in 5/25 (20%) and 16/32 (50%) patients respectively. Nine grade 3 adverse events (AEs) occurred in six patients, but there were no grade ≥4 AEs. Ten of the 32 patients experienced grade 2 renal toxicity. Low-dose CsA is effective in TI-NSAA patients and demonstrates minimal renal toxicity. However, at least 16 weeks are necessary to adequately evaluate its efficacy. en-copyright= kn-copyright= en-aut-name=IshiyamaKen en-aut-sei=Ishiyama en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamazakiMasahide en-aut-sei=Yamazaki en-aut-mei=Masahide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MaruyamaHiroyuki en-aut-sei=Maruyama en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HosonoNaoko en-aut-sei=Hosono en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamaguchiHiroki en-aut-sei=Yamaguchi en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=TanimotoKazuki en-aut-sei=Tanimoto en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SugiuraHiroyuki en-aut-sei=Sugiura en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=UsukiKensuke en-aut-sei=Usuki en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=YoshimuraKenichi en-aut-sei=Yoshimura en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OgawaSeishi en-aut-sei=Ogawa en-aut-mei=Seishi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KanakuraYuzuru en-aut-sei=Kanakura en-aut-mei=Yuzuru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MatsumuraItaru en-aut-sei=Matsumura en-aut-mei=Itaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=AkashiKoichi en-aut-sei=Akashi en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=NakaoShinji en-aut-sei=Nakao en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil=Department of Hematology, Kanazawa University Hospital kn-affil= affil-num=2 en-affil=Department of Internal Medicine, Keiju Medical Center kn-affil= affil-num=3 en-affil=Department of Hematology, Kanazawa University Hospital kn-affil= affil-num=4 en-affil=Department of Hematology and Oncology, University of Fukui Hospital kn-affil= affil-num=5 en-affil=Department of Hematology, Nippon Medical School kn-affil= affil-num=6 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Hematology and Oncology, Japanese Red Cross Fukuoka Hospital kn-affil= affil-num=8 en-affil=Department of Hematology, Chugoku Central Hospital of Japan Mutual Aid Association of Public School Teachers kn-affil= affil-num=9 en-affil=Department of Hematology, NTT Medical Center Tokyo kn-affil= affil-num=10 en-affil=Department of Biostatistics and Health Data Science, Graduate School of Medical Science, Nagoya City University kn-affil= affil-num=11 en-affil=Department of Pathology and Tumor Biology, Institute for the Advanced Study of Human Biology (WPI-ASHBi), Kyoto University kn-affil= affil-num=12 en-affil=Sumitomo Hospital kn-affil= affil-num=13 en-affil=Department of Hematology and Rheumatology, Kindai University Faculty of Medicine kn-affil= affil-num=14 en-affil=Department of Medicine and Biosystemic Science, Kyushu University Graduate School of Medical Sciences kn-affil= affil-num=15 en-affil=Department of Hematology, Kanazawa University Hospital kn-affil= en-keyword=ciclosporin kn-keyword=ciclosporin en-keyword=prospective study kn-keyword=prospective study en-keyword=renal toxicity kn-keyword=renal toxicity en-keyword=transfusion-independent non-severe aplastic anaemia kn-keyword=transfusion-independent non-severe aplastic anaemia END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=6 article-no= start-page=e098532 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=Protocol for a multicentre, open-label, dose-escalation phase I/II study evaluating the tolerability, safety, efficacy and pharmacokinetics of repeated continuous intravenous PPMX-T003 in patients with aggressive natural killer cell leukaemia en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction Aggressive natural killer cell leukaemia (ANKL) is a rare form of NK cell lymphoma with a very low incidence and poor prognosis. While multi-agent chemotherapy including L-asparaginase has been used to treat ANKL patients, they often cannot receive adequate chemotherapy at diagnosis due to liver dysfunction. PPMX-T003, a fully human monoclonal antibody targeting the transferrin receptor 1, shows promise in treating ANKL by helping patients recover from fulminant clinical conditions, potentially enabling a transition to chemotherapy. This study aimed to evaluate the tolerability, safety, efficacy, and pharmacokinetics of repeated continuous intravenous PPMX-T003 in patients with ANKL.
Methods and analysis This multicentre, open-label, dose-escalation phase I/II study will be conducted at nine hospitals in Japan. Patients diagnosed with ANKL (whether as a primary or recurrent disease) and exhibiting abnormal liver function or hepatomegaly due to the primary disease will be included. The primary endpoint is the tolerability and safety of repeated continuous intravenous administration of PPMX-T003 in the first course, based on adverse events and dose-limiting toxicities. PPMX-T003 will be administered as a continuous intravenous infusion every 24 hours for five consecutive days, followed by a 2-day break. Pretreatment will be provided to minimise the risk of infusion-related reactions. Initial doses of PPMX-T003 will be 0.5, 1.0 or 2.0 mg/kg, with subsequent dose increases determined by the Data and Safety Monitoring Committee. The sample size is set at seven participants, with enrolment increased to up to 12 participants if dose-limiting toxicities occur, based on feasibility due to the rarity of ANKL.

Nutrient deficiency, compounded by antibiotic-induced nutrient depletion, forms a vicious cycle of overt inflammation, contributing to bacterial toxin translocation in human inter-organ and intra-organs milieus. Coenzyme Q10 (CoQ10) and omega-6 linoleic acid (LA 18:2ω6) are integral to cellular membrane integrity and immune defense. However, the complex enzymatic steps at the host cell-pathogen interface remain poorly understood. This study is particularly timely, as it explores these knowledge gaps, which can inform the development of nutritional and therapeutic strategies that modulate or target these mechanisms. Using an infectious-inflamed cell co-culture model of the gut-liver axis, we exposed triple cell co-cultures of human intestinal epithelial cells (T84), macrophage-like THP-1 cells, and hepatic cells (Huh7) to linoleic acid-producing Lactobacillus casei (L. casei) and Pseudomonas aeruginosa strain PAO1 (PAO1). The cultures were incubated for 6 h in medium with or without ceftazidime antibiotic. PAO1 and L. casei exerted opposing effects on the secretion of Th1 cytokines IL-1β, IL-6, and the Th 2-type cytokine IL-10. Inoculation with PAO1 decreased CoQ10 and linoleic acid levels compared to uninfected controls. L. casei restored cellular health and biofunctionality impaired by PAO1, indicating its benefit to the host's well-being. The antibiotic ceftazidime exerted dual effects, alleviating PAO1 toxicity while marginally disrupting the beneficial effects of L. casei. Our results show how the vicious cycle of nutrient deficiency and antibiotic-induced nutrient loss reinforces pathological inflammation at the host cell-pathogen interface and highlights the need for more appropriate targeted antibiotic use that preserves essential nutrients like CoQ10 and omega-6 fatty acids. Inflammatory responses driven by opportunistic pathogens and LA-producing bacteria represent opposing immunometabolic pathways that may provide insights into novel approaches for treating infection and reducing antibiotic resistance. en-copyright= kn-copyright= en-aut-name=GhadimiDarab en-aut-sei=Ghadimi en-aut-mei=Darab kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=BlömerSophia en-aut-sei=Blömer en-aut-mei=Sophia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Şahi̇n KayaAysel en-aut-sei=Şahi̇n Kaya en-aut-mei=Aysel kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KrügerSandra en-aut-sei=Krüger en-aut-mei=Sandra kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=RöckenChristoph en-aut-sei=Röcken en-aut-mei=Christoph kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SchäferHeiner en-aut-sei=Schäfer en-aut-mei=Heiner kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=UchiyamaJumpei en-aut-sei=Uchiyama en-aut-mei=Jumpei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MatsuzakiShigenobu en-aut-sei=Matsuzaki en-aut-mei=Shigenobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=BockelmannWilhelm en-aut-sei=Bockelmann en-aut-mei=Wilhelm kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Microbiology and Biotechnology, Max Rubner-Institut kn-affil= affil-num=2 en-affil=Faculty of Medicine, Christian-Albrechts-University of Kiel kn-affil= affil-num=3 en-affil=Department of Nutrition and Dietetics, Faculty of Health Sciences, Antalya Bilim University kn-affil= affil-num=4 en-affil=Institute of Pathology, Kiel University, University Hospital, Schleswig-Holstein kn-affil= affil-num=5 en-affil=Institute of Pathology, Kiel University, University Hospital, Schleswig-Holstein kn-affil= affil-num=6 en-affil=Laboratory of Molecular Gastroenterology & Hepatology, Christian-Albrechts-University & UKSH Campus Kiel kn-affil= affil-num=7 en-affil=Department of Bacteriology, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Medical Laboratory Science, Faculty of Health Sciences, Kochi Gakuen University kn-affil= affil-num=9 en-affil=Department of Microbiology and Biotechnology, Max Rubner-Institut kn-affil= en-keyword=Antibiotics kn-keyword=Antibiotics en-keyword=Coenzyme Q10 kn-keyword=Coenzyme Q10 en-keyword=Infection kn-keyword=Infection en-keyword=Inflammation kn-keyword=Inflammation en-keyword=Micronutrients kn-keyword=Micronutrients en-keyword=Oxidative stress kn-keyword=Oxidative stress 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=20251110 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Japanese society for cancer of the colon and rectum (JSCCR) guidelines 2024 for the clinical practice of hereditary colorectal cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Approximately 5% of all colorectal cancers have a strong genetic component and are classified as hereditary colorectal cancer (HCRC). Some of the unique features commonly seen in HCRC cases include early age of onset, synchronous/metachronous cancer occurrence, and multiple cancers in other organs. These characteristics require different management approaches, including diagnosis, treatment or surveillance, from those used in the management of sporadic colorectal cancer. Accurate diagnosis of HCRC is essential because it enables targeted surveillance and risk reduction strategies that improve patient outcomes. Recent genetic advances revealed several causative genes for polyposis and non-polyposis syndromes. The Japanese Society for Cancer of the Colon and Rectum (JSCCR) first published guidelines for the management of HCRC in 2012, with subsequent revisions every 4 years. The 2024 update to the JSCCR guidelines for HCRC was developed by meticulously reviewing evidence from systematic reviews and the consensus of the JSCCR HCRC Guidelines Committee, which includes representatives from patient advocacy groups for FAP and Lynch syndrome. These guidelines provide an up-to-date summary of HCRC, along with clinical recommendations for managing FAP and Lynch syndrome. en-copyright= kn-copyright= en-aut-name=TanakayaKohji

case report en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report a rare case of protein-losing enteropathy (PLE) during zolbetuximab treatment in a 73-year-old woman with Stage IVB gastric cancer. After chemo-immunotherapy and curative surgery, 3rd-line treatment with capecitabine, oxaliplatin, and zolbetuximab was initiated due to recurrence. The patient developed persistent right upper abdominal pain; imaging revealed gallbladder wall edema, followed by mild gastric wall edema, despite unremarkable laboratory findings. Protein-losing scintigraphy demonstrated abnormal gastric protein leakage, leading to a diagnosis of PLE. While gastrointestinal toxicity is known with zolbetuximab, this is, to our knowledge, the first clinically diagnosed case of PLE in which gallbladder edema served as a diagnostic clue. As treatment strategies for advanced gastric cancer grow increasingly complex, achieving maximum therapeutic benefit requires not only optimal drug selection but also timely recognition and management of adverse events. With the broader use of zolbetuximab, clinicians should be mindful of this rare but potentially significant complication. 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=HanzawaShunya en-aut-sei=Hanzawa en-aut-mei=Shunya 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=ShigeyasuKunitoshi en-aut-sei=Shigeyasu en-aut-mei=Kunitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 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=9 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=10 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 Gastroenterological Surgery, Dentistry and Pharmaceutical Sciences, Okayama 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 Gastroenterology and Hepatology, 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= affil-num=10 en-affil=Department of Gastroenterological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= en-keyword=Gastric cancer kn-keyword=Gastric cancer en-keyword=Zolbetuximab kn-keyword=Zolbetuximab en-keyword=CLDN 18.2 kn-keyword=CLDN 18.2 en-keyword=Protein-losing enteropathy kn-keyword=Protein-losing enteropathy en-keyword=Gallbladder edema kn-keyword=Gallbladder edema END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=11 article-no= start-page=e97797 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251125 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Long-Term Outcome of Xenon-Arc Photocoagulation for Retinopathy of Prematurity in the 1970s in Japan: Eleven Patients With 32- to 49-Year Follow-Up en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: Photocoagulation or cryocautery, or their combinations, are the standard of care for retinopathy of prematurity at the recommended timing, which is based on the International Classification of Retinopathy of Prematurity. In Japan, the effectiveness of xenon-arc photocoagulation and cryocautery in retinopathy of prematurity was reported on an empirical basis first in 1968, and became the standard of care in retinopathy of prematurity in the 1970s, 10 years earlier compared with the other countries. In this study, we reported the up to 49 years visual outcome of 11 patients with retinopathy of prematurity who underwent xenon-arc photocoagulation and cryocautery in the 1970s.
Methods: A retrospective review was made on the medical records of 11 consecutive patients who underwent xenon-arc photocoagulation for retinopathy of prematurity in the years 1974 to 1980, and were followed up until the period from 2009 to 2025. The birthweight ranged from 865 g to 2300 g at a median of 1350 g, and the gestational age at birth ranged from 27 weeks to 36 weeks at a median of 30 weeks. The corrected gestational age at the time of photocoagulation ranged from 32 weeks to 53 weeks, with a median of 37 weeks. Oxygen was given to all 11 patients, except for one who was born in the earliest year 1974. The retinopathy of prematurity was at stage 3 in both eyes of seven patients, with plus disease signs in four patients, at stage 2 with and without plus disease in two patients, at stage 2 and stage 3 in each eye of one patient, and at stage 1 with plus disease in both eyes of one patient. The entire 360-degree photocoagulation was given in seven patients, while partial photocoagulation was applied in four patients. Additional cryocautery was applied in six patients.
Results: The age at the last visit ranged from 32 to 49 years with a median of 46 years. At the last visit, seven patients showed the best-corrected visual acuity in decimals of 0.8 or better in both eyes. One dizygotic twin showed no light perception in the phthisic right eye and 0.1 in the left eye with macular degeneration and nystagmus after he underwent cataract surgery at the age of 34 years. The other twin had the best-corrected visual acuity of 0.5 in the right eye and 0.02 in the left eye due to macular degeneration after he underwent cataract surgeries in both eyes at the age of 36 years. Two patients developed rhegmatogenous retinal detachment in one eye at the age of 44 and 41 years, respectively, and underwent vitrectomy with silicone oil tamponade, resulting in visual acuity of 0.1 and 0.3, respectively. Two patients experienced vitreous hemorrhage in one eye, which was absorbed spontaneously at the ages of 37 years and 42 years, respectively. One patient underwent partial scleral buckling for localized rhegmatogenous retinal detachment. No patient used intraocular pressure-lowering eyedrops.
Conclusion: Most patients with xenon-arc photocoagulation for retinopathy of prematurity in the 1970s maintained standard levels of visual acuity up to 49 years in the follow-up. Cataract, retinal detachment, and vitreous hemorrhage were noted as late complications and were coped with on an individual basis. The conclusion would have a meaning, even though not novel, that the patients with retinopathy of prematurity would have benefited from the xenon-arc photocoagulation and cryocautery. 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=MatsuoNobuhiko en-aut-sei=Matsuo en-aut-mei=Nobuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Healthcare Science, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Ophthalmology, Okayama University Medical School kn-affil= en-keyword=1970s kn-keyword=1970s en-keyword=cataract kn-keyword=cataract en-keyword=cryocautery kn-keyword=cryocautery en-keyword=japan kn-keyword=japan en-keyword=late complications kn-keyword=late complications en-keyword=neonatology kn-keyword=neonatology en-keyword=retinal detachment kn-keyword=retinal detachment en-keyword=retinopathy of prematurity kn-keyword=retinopathy of prematurity en-keyword=vitreous hemorrhage kn-keyword=vitreous hemorrhage en-keyword=xenon-arc photocoagulation kn-keyword=xenon-arc photocoagulation END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=1 article-no= start-page=670 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250929 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Neoadjuvant chemotherapy strategies for optimizing safety and efficacy in elderly patients with locally advanced gastric cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background The completion rate of adjuvant chemotherapy for gastric cancer (GC) is suboptimal, particularly in elderly patients. While neoadjuvant chemotherapy (NAC) for locally advanced GC has shown promise, data on elderly patients remain limited. Given the considerable physical burden of NAC, optimizing its administration is crucial. This study evaluates the safety and efficacy of a modified approach for elderly patients.
Methods A retrospective analysis was conducted on 38 patients with cStage II/III GC who received NAC between November 2015 and December 2023. Additionally, 25 patients aged ≥ 75 years with cStage III who underwent upfront surgery during the same period were analyzed.
Results The NAC group was divided into non-elderly (< 75 years, n = 27) and elderly (≥ 75 years, n = 11) groups. The elderly group had poorer ECOG-PS (p = 0.016). While all non-elderly patients completed ≤ 3 cycles, more elderly patients underwent 4 cycles (p = 0.0047). However, per-cycles of S-1 (p = 0.0003) and oxaliplatin (p = 0.0018) were lower in the elderly group. Importantly, adverse events and treatment efficacy were comparable between groups. Among patients aged ≥ 75 years, the upfront surgery group had poorer ECOG-PS (p = 0.017) and underwent more frequent distal gastrectomy (p = 0.014).
Conclusions NAC can be safely administered to elderly patients by increasing cycles while reducing per-cycle dosage. It may also serve as a viable alternative to upfront surgery. 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=HanzawaShunya en-aut-sei=Hanzawa en-aut-mei=Shunya 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=ShigeyasuKunitoshi en-aut-sei=Shigeyasu en-aut-mei=Kunitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=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 Gastroenterological Surgery, Dentistry and Pharmaceutical Sciences, Okayama 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=Gastric cancer kn-keyword=Gastric cancer en-keyword=Neoadjuvant chemotherapy kn-keyword=Neoadjuvant chemotherapy en-keyword=Elderly kn-keyword=Elderly en-keyword=Adverse events kn-keyword=Adverse events END start-ver=1.4 cd-journal=joma no-vol=81 cd-vols= no-issue= article-no= start-page=152587 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202604 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The diagnostic utility and frequency of CD56 expression in plasma cell myeloma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Plasma cell myeloma (PCM) is a hematological malignancy characterized by systemic proliferation of neoplastic plasma cells within the bone marrow. Diagnosis requires clinical findings and immunohistochemical staining, including CD138, CD79a, cyclin D1, immunoglobulin κ (Igκ), and λ (Igλ). However, CD79a and cyclin D1 have limited sensitivity and specificity, and Igκ/Igλ assessment is often difficult due to overstaining. Therefore, more reliable antibodies are needed to accurately diagnose PCM. In this study, we examined the diagnostic utility of CD56 expression in PCM. We retrospectively performed immunostaining for CD138, CD56, CD79a, cyclin D1, Igκ, and Igλ in bone marrow samples from 116 patients with PCM.
CD56 expression was observed in 85/116 cases (73.3 %), CD79a was downregulated in 46/116 cases (39.7 %), and cyclin D1 expression was observed in 42/116 cases (36.2 %). The expression of CD56 was significantly higher than that of CD79a and cyclin D1 (both p < 0.001). The combination of two antibodies resulted in the highest detection rate when combining CD56 and CD79a (105/116, 90.5 %), which was significantly higher than the detection rates of CD56 and cyclin D1 (93/116, 80.2 %) and CD79a and cyclin D1 (75/116, 64.7 %) (both p < 0.001). In contrast, lymphoplasmacytic lymphoma and marginal zone lymphoma lacked CD56 and cyclin D1 expression. Furthermore, in cases where light chain restriction was undetectable (11/116, 9.5 %), all could be diagnosed as PCM based on CD56, CD79a, and cyclin D1. Among these, CD56 showed the highest detection rate (8/11, 72.7 %).
These findings highlight CD56 as a helpful marker for PCM diagnosis and support further clinical research.

We conducted both the Short-term Test and the Standard Test using an FZG gear test machine to evaluate how lubricant additives and gear surface roughness influence damage progression when the surface roughness exceeds the oil-film thickness. Acid phosphate ester effectively suppressed micropitting through surface smoothing but led to severe damage such as pitting and scuffing during prolonged use. In contrast, sulfurized fatty oil promoted mild wear, delaying catastrophic failures and extending gear life. Higher surface roughness accelerated wear, while increased hardness reduced deformation but it expanded damage areas. The study found that initial surface roughness and its progress during load stages strongly correlate with gear durability. Measurement of arithmetic mean roughness after sufficient running-in under actual load conditions proved useful for predicting long-term performance. These findings highlight the importance of selecting lubricant formulations tailored to specific gear operating environments and damage modes. Understanding the interplay between lubrication chemistry and material properties enables the design of more durable gear systems. en-copyright= kn-copyright= en-aut-name=OhnoTakuya en-aut-sei=Ohno en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShiotaTadashi en-aut-sei=Shiota en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiiMasahiro en-aut-sei=Fujii en-aut-mei=Masahiro 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=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= en-keyword=Tribology kn-keyword=Tribology en-keyword=Gears kn-keyword=Gears en-keyword=Fatigue kn-keyword=Fatigue en-keyword=Micropitting kn-keyword=Micropitting en-keyword=Scuffing kn-keyword=Scuffing en-keyword=Pitting kn-keyword=Pitting en-keyword=Lubricant additives kn-keyword=Lubricant additives END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=3 article-no= start-page=124 end-page=129 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=Water Lubrication of Polysiloxane-Containing Polyimide Coatings on Stainless Steel Substrates en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study investigated the water-lubricated tribological properties of coatings made of a novel polysiloxane-containing polyimide (si-PI) material that was recently developed for the aerospace industry and can be diluted with the harmless and environmentally friendly ethanol or water. The si-PI coatings were deposited on stainless steel (JIS SUS304) substrates at curing temperatures ranging from 160°C to 275°C. Their water lubrication properties were measured by rubbing the coatings against each other in water at room temperature. The coatings exhibited lower friction than conventional polyimide materials, with a minimum friction coefficient of 0.04, which was lower than that of polytetrafluoroethylene (PTFE) measured under the same sliding conditions. Unlike the conventional polyimide, the coatings did not exhibit any obvious wear or damage. The results demonstrate that the si-PI coating is a promising low-friction and highly durable coating for water lubrication. en-copyright= kn-copyright= en-aut-name=FanYuelin en-aut-sei=Fan en-aut-mei=Yuelin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShiotaTadashi en-aut-sei=Shiota en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OmiyaYuya en-aut-sei=Omiya en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujiiMasahiro en-aut-sei=Fujii en-aut-mei=Masahiro 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= en-keyword=polyimide kn-keyword=polyimide en-keyword=polysiloxane kn-keyword=polysiloxane en-keyword=resin coating kn-keyword=resin coating en-keyword=water lubrication kn-keyword=water lubrication en-keyword=wear resistance kn-keyword=wear resistance END start-ver=1.4 cd-journal=joma no-vol=152 cd-vols= no-issue=22 article-no= start-page=dev204763 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251115 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=ROS produced by Dual oxidase regulate cell proliferation and haemocyte migration during leg regeneration in the cricket en-subtitle= kn-subtitle= en-abstract= kn-abstract=Many animals regenerate lost body parts through several signalling pathways; however, the triggers that initiate regeneration remain unclear. In the present study, we focused on the role of reactive oxygen species (ROS) produced by the NADPH oxidase Dual oxidase (Duox) during cricket leg regeneration. The results showed that ROS levels were upregulated during leg regeneration and decreased by DuoxRNAi. In DuoxRNAi nymphs, wound closure and scab formation were incomplete 2 days after amputation, and hypertrophy occurred in the distal region of the regenerating legs at 5 days after amputation. In addition, the hypertrophic phenotype was induced by DuoxARNAi and NADPH oxidase inhibitor treatment. During hypertrophy, haemocytes, including plasmatocytes, oenocytoids and granulocytes, accumulated. Proliferation of haemocytes in regenerating legs was not increased by DuoxRNAi; however, haemocyte accumulation was regulated by the Spatzle (Spz) family molecules, which are Toll receptor ligands. As the exoskeleton of DuoxRNAi nymphs was thinner than that of the control, excessive haemocyte accumulation can cause hypertrophy in DuoxRNAi nymphs. Thus, Duox-derived ROS are involved in wound healing and haemocyte accumulation through the Spz/Toll signalling pathway during leg regeneration in crickets. en-copyright= kn-copyright= en-aut-name=Okumura-HironoMisa en-aut-sei=Okumura-Hirono en-aut-mei=Misa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=BandoTetsuya en-aut-sei=Bando en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HamadaYoshimasa en-aut-sei=Hamada en-aut-mei=Yoshimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=OhuchiHideyo en-aut-sei=Ohuchi en-aut-mei=Hideyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Cytology and Histology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cytology and Histology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Cytology and Histology, 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 Cytology and Histology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Regeneration kn-keyword=Regeneration en-keyword=Reactive oxygen species (ROS) kn-keyword=Reactive oxygen species (ROS) en-keyword=NADPH oxidase (Nox) kn-keyword=NADPH oxidase (Nox) en-keyword=Dual oxidase (Duox) kn-keyword=Dual oxidase (Duox) en-keyword=Inflammation kn-keyword=Inflammation en-keyword=Gryllus bimaculatus kn-keyword=Gryllus bimaculatus END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=1 article-no= start-page=366 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251121 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Synthesis of thienoacenes by electrochemical double C–S cyclization using a halogen mediator en-subtitle= kn-subtitle= en-abstract= kn-abstract=Thienoacenes are significant compounds as organic materials. One of the most efficient ways to synthesize thienoacenes is to form multiple C–S bonds in a single step. Because unprotected S–H bonds are easily oxidized to S–S bonds, S-Me protected substrates are commonly used for the purpose. However, their reactivity is insufficient, and one-step construction of multiple C–S bonds is still challenging. We herein report the electrochemical synthesis of thienoacenes from S-methoxymethyl (MOM)-protected diarylacetylenes. In the presence of Bu4NBr as a halogen mediator, electrochemical double C–S cyclization of diarylacetylenes bearing two MOM groups proceeded to afford [1]benzothieno[3,2-b][1]benzothiophene (BTBT) derivatives. While S-Me or S-p-methoxybenzyl (PMB)-protected diarylacetylenes did not afford BTBT, BTBT was selectively obtained when a substrate protected with S-MOM groups was used. The S-MOM protection strategy is also effective for the electrochemical synthesis of a more π-expanded thienoacene such as dibenzo[d,d′]thieno[3,2-b,4,5-b′]dithiophene (DBTDT). en-copyright= kn-copyright= en-aut-name=MitsudoKoichi en-aut-sei=Mitsudo en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NagaharaTakuya en-aut-sei=Nagahara en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KatauraNozomi en-aut-sei=Kataura en-aut-mei=Nozomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OkamuraYuka en-aut-sei=Okamura en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YonezawaToki en-aut-sei=Yonezawa en-aut-mei=Toki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TachibanaYuri en-aut-sei=Tachibana en-aut-mei=Yuri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SouliéNolan en-aut-sei=Soulié en-aut-mei=Nolan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ShigemoriKeisuke en-aut-sei=Shigemori en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SatoEisuke en-aut-sei=Sato en-aut-mei=Eisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 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=11 ORCID= affil-num=1 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Faculty of Science and Engineering, Sorbonne Université kn-affil= affil-num=8 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=9 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=10 en-affil=Department of Pharmacy, Faculty of Pharmacy, Gifu University of Medical Science kn-affil= affil-num=11 en-affil=Division of Applied Chemistry, Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= 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=20251124 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluation of the small-field output factor in eclipse modeling methods using representative beam and measured data with averaged ionization chamber and diode detector measurements en-subtitle= kn-subtitle= en-abstract= kn-abstract=Beam modeling for radiotherapy treatment planning systems (RTPS) can be performed using representative beam data (RBD) or direct measurements. However, RBD typically excludes output factor (OPF) measurements for fields smaller than 3 × 3 cm2. The Eclipse treatment planning system addresses this limitation by incorporating measured OPF data for fields as small as 1 × 1 cm2. Although existing studies have primarily examined the accuracy of small-field OPFs for plastic scintillator detectors, studies directly comparing the OPF values obtained through RBD modeling with and without OPF measurements for small field sizes are limited. Therefore, this study proposes a novel measurement approach using data averaged from an ion chamber and diode detector for small-field dosimetry to provide critical insights into the integration of OPFs for these small field sizes in RBD-based beam modeling. We systematically evaluated the impact of small-field OPF measurements on beam modeling accuracy by comparing three distinct approaches: (1) RBD-based modeling without small-field OPF data, (2) RBD-based modeling incorporating measured small-field OPF data, and (3) modeling based solely on measured data, with and without the inclusion of 1 × 1 cm2 field sizes. In addition, we compared OPF values obtained from a W2 plastic scintillator detector with the averaged OPF values from a PinPoint 3D ion chamber and EDGE diode detector across multiple beam energies and flattening filter-free (FFF) configurations. Our analysis included field sizes ranging from 1 × 1 cm2 to 40 × 40 cm2. The results demonstrated that for square fields, OPF calculation differences between RBD modeling with and without measured data were < 1.5%, < 4.5%, and < 4.5% at 1 × 1 cm2, and < 0.5%, < 1.5%, and < 1.5% at 2  ×  2 cm2, respectively. The RBD group exhibited a trend in which the OPF difference increased with the expansion of the irradiation field size. Notably, the most significant variations between modeling approaches occurred along the upper jaw expansion direction in rectangular fields. This suggests that a thorough evaluation is necessary for modeling results with an OPF ≤  1 × 1 cm2. This study highlights the advantages and disadvantages of beam modeling using measured OPF and RBD, providing valuable insights for future facilities that rely solely on RBD for beam modeling. en-copyright= kn-copyright= en-aut-name=NishiokaKunio en-aut-sei=Nishioka en-aut-mei=Kunio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KuniiYuki en-aut-sei=Kunii en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=SakamotoYuichi en-aut-sei=Sakamoto en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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=6 ORCID= affil-num=1 en-affil=Department of Radiology, Tokuyama Central Hospital kn-affil= affil-num=2 en-affil=Department of Radiology, Tokuyama Central Hospital kn-affil= affil-num=3 en-affil=Department of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Radiology, Tokuyama Central Hospital kn-affil= affil-num=5 en-affil=Department of Radiology, Tokuyama Central Hospital kn-affil= affil-num=6 en-affil=Department of Radiology, Tokuyama Central Hospital kn-affil= en-keyword=Beam modeling kn-keyword=Beam modeling en-keyword=Plastic scintillator detector kn-keyword=Plastic scintillator detector en-keyword=Small irradiation field kn-keyword=Small irradiation field en-keyword=Output factor kn-keyword=Output factor END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=11 article-no= start-page=e70168 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202511 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Comparative Genomic Analysis Identifies FleQ and GcbB as Virulence-Associated Factors in Pseudomonas syringae pv. tabaci Strains en-subtitle= kn-subtitle= en-abstract= kn-abstract=Pseudomonas syringae pv. tabaci (Pta) is an important plant pathogen, which causes wildfire disease in Nicotiana species. However, the genetic basis underlying strain-level differences in virulence remains largely unresolved. To address this, we performed a comparative genomic analysis between a highly virulent strain Pta6605 and a less virulent strain Pta7375. Despite high overall genome similarity, we identified key single-nucleotide polymorphisms, including premature stop-codon mutations in seven open reading frames in Pta7375. Notably, point mutations in two regulatory genes, such as fleQ, which encodes a transcription factor essential for flagellar biogenesis and biofilm formation, and gcbB, which encodes a GGDEF domain-containing diguanylate cyclase responsible for cyclic dimeric guanosine monophosphate (c-di-GMP) synthesis, were implicated in virulence disparity. Functional analyses using deletion and locus replacement mutants in the Pta6605 background revealed that the disruption of fleQ markedly reduced motility, flagellin production, c-di-GMP accumulation, biofilm formation and virulence level mirroring the Pta7375 phenotype. The gcbB replacement mutant showed reduced disease symptom development, although c-di-GMP levels remained comparable to the Pta6605 wild type. Locus replacement between strains confirmed that a point mutation in fleQ was the primary driver of reduced motility and flagellin expression in Pta7375. These findings indicate that the reduced virulence of Pta7375 is associated with impaired regulation of flagella-related genes and disruption of the FleQ-mediated c-di-GMP signalling, underscoring the value of comparative genomics in disentangling the complex regulatory networks that govern virulence in plant pathogens. en-copyright= kn-copyright= en-aut-name=HidayatMuhammad Taufiq en-aut-sei=Hidayat en-aut-mei=Muhammad Taufiq kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshiokaKei en-aut-sei=Yoshioka en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishimuraTakafumi en-aut-sei=Nishimura en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AsaiShuta en-aut-sei=Asai en-aut-mei=Shuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MasudaSachiko en-aut-sei=Masuda en-aut-mei=Sachiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShirasuKen en-aut-sei=Shirasu en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SakataNanami en-aut-sei=Sakata en-aut-mei=Nanami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamamotoMikihiro en-aut-sei=Yamamoto en-aut-mei=Mikihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NoutoshiYoshiteru en-aut-sei=Noutoshi en-aut-mei=Yoshiteru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ToyodaKazuhiro en-aut-sei=Toyoda en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=IchinoseYuki en-aut-sei=Ichinose en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=MatsuiHidenori en-aut-sei=Matsui en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 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 Agriculture, 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=Center for Sustainable Resource Science, RIKEN-TRIP kn-affil= affil-num=6 en-affil=Center for Sustainable Resource Science, RIKEN-TRIP kn-affil= affil-num=7 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=8 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=9 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=10 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=11 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=12 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=comparative genomics kn-keyword=comparative genomics en-keyword=cyclic-di- GMP kn-keyword=cyclic-di- GMP en-keyword=fleQ kn-keyword=fleQ en-keyword=gcbB kn-keyword=gcbB en-keyword=Pseudomonas syringae kn-keyword=Pseudomonas syringae 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=20251119 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Role of the Mylohyoid Line in the Spread of Mandibular Odontogenic Deep Neck Infection en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Although mandibular odontogenic deep neck infections are occasionally fatal, the transmission pathway has not been elucidated.
Materials and Methods: This multicenter retrospective study was comprised of the patients of both sexes who were over 18 years of age and who had mandibular odontogenic deep neck abscesses. The patients' characteristics, laboratory tests, and radiographic findings were analyzed.
Results: One hundred eighteen patients with mandibular odontogenic deep neck abscesses were included. Bone resorption superior to the mylohyoid line and the related abscess formation in submandibular space or submental space were both significantly associated with the presence of sublingual space abscess. In addition, the type of causative tooth was not a risk factor for abscess formation in both the sublingual space and “submandibular or submental” space.
Conclusions: When an odontogenic lesion is located superior to the mylohyoid line, the abscess tends to initially form in the sublingual space and subsequently spread to the submandibular or submental space. Since any mandibular tooth can lead to abscess formation in these regions, oral and maxillofacial surgeons should carefully assess the anatomical position of the lesion and accurately identify the causative tooth. en-copyright= kn-copyright= en-aut-name=IwataEiji en-aut-sei=Iwata en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ObataKyoichi

Data From a Nationwide Genomic Database en-subtitle= kn-subtitle= en-abstract= kn-abstract=Next-generation sequencing-based comprehensive cancer genomic profiling is promising in cancer management; however, most studies rely on tumor-only DNA panels from single institutions. In 2023, Japan introduced an insurance-covered cancer genomic profiling test—the GenMine TOP Cancer Genome Profiling System—a dual DNA–RNA panel with matched tumor–normal testing. This study evaluated its utility compared to a conventional DNA-only test (FoundationOne CDx) in managing sarcoma patients using a nationwide genetic profiling database provided by the Center for Cancer Genomics and Advanced Therapeutics. This study included 1046 patients registered between August 2023 and October 2024. The dual DNA–RNA test identified significantly more fusion genes (20.3% vs. 7.4%, p < 0.001) and therapeutically targetable kinase fusions (3.5% vs. 1.2%, p = 0.019) than the DNA-only test. Among patients with translocation-related sarcomas, histology-specific fusion genes were identified in 77.5% using the dual panel, compared to 40.0% with the DNA-only panel (p < 0.001). In non-gastrointestinal stromal tumor sarcomas, the dual test showed a trend toward higher rates of genotype-matched therapy (4.3% vs. 2.6%, p = 0.25) and a significantly higher rate of molecular targeted therapy (4.3% vs. 1.5%, p = 0.03). Additionally, 5.7% of patients had pathogenic germline variants identified through tumor–normal matched analysis. These findings suggest that a dual DNA–RNA panel with matched tumor–normal testing may improve diagnostic accuracy and inform treatment decisions in the routine clinical management of sarcoma. en-copyright= kn-copyright= en-aut-name=NakataEiji en-aut-sei=Nakata en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NinomiyaKiichiro en-aut-sei=Ninomiya en-aut-mei=Kiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OsoneTatsunori en-aut-sei=Osone en-aut-mei=Tatsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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=5 ORCID= en-aut-name=FujiwaraTomohiro en-aut-sei=Fujiwara en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KunisadaToshiyuki en-aut-sei=Kunisada en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FutagawaMashu en-aut-sei=Futagawa en-aut-mei=Mashu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 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=10 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=11 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=Center for Comprehensive Genomic Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences 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=Center for Comprehensive Genomic Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Center for Comprehensive Genomic Medicine, 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= affil-num=8 en-affil=Department of Clinical Genomic Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Clinical Genomic Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=comprehensive cancer genomic profiling (CGP) kn-keyword=comprehensive cancer genomic profiling (CGP) en-keyword=fusion genes kn-keyword=fusion genes en-keyword=gene alterations kn-keyword=gene alterations en-keyword=genotype-matched therapy kn-keyword=genotype-matched therapy en-keyword=potential germline variants (PGVs) kn-keyword=potential germline variants (PGVs) END start-ver=1.4 cd-journal=joma no-vol=386 cd-vols= no-issue= article-no= start-page=115145 end-page= 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=Therapeutic effects of intracerebral transplantation of human modified bone marrow-derived stromal cells (SB623) with voluntary and forced exercise in a rat model of ischemic stroke en-subtitle= kn-subtitle= en-abstract= kn-abstract=Ischemic stroke results in significant long-term disability and mortality worldwide. Although existing therapies, such as recombinant tissue plasminogen activator and mechanical thrombectomy, have shown promise, their application is limited by stringent conditions. Mesenchymal stem cell (MSC) transplantation, especially using SB623 cells (modified human bone marrow-derived MSCs), has emerged as a promising alternative, promoting neurogenesis and recovery. This study evaluated the effects of voluntary and forced exercise, alone and in combination with SB623 cell transplantation, on neurological and psychological outcomes in a rat model of ischemic stroke. Male Wistar rats that had undergone middle cerebral artery occlusion (MCAO) were divided into six groups: control, voluntary exercise (V-Ex), forced exercise (F-Ex), SB623 transplantation, SB623 + V-Ex, and SB623 + F-Ex. Voluntary exercise was facilitated using running wheels, while forced exercise was conducted on treadmills. Neurological recovery was assessed using the modified neurological severity score (mNSS). Psychological symptoms were evaluated through the open field test (OFT) and forced swim test (FST), and neurogenesis was assessed via BrdU labeling. Both exercise groups exhibited significant changes in body weight post-MCAO. Both exercises enhanced the treatment effect of SB623 transplantation. The forced exercise showed a stronger treatment effect on ischemic stroke than voluntary exercise alone, and the sole voluntary exercise improved depression-like behavior. The SB623 + F-Ex group demonstrated the greatest improvements in motor function, infarct area reduction, and neurogenesis. The SB623 + V-Ex group was most effective in alleviating depression-like behavior. Future research should optimize these exercise protocols and elucidate the underlying mechanisms to develop tailored rehabilitation strategies for stroke patients. en-copyright= kn-copyright= en-aut-name=NagaseTakayuki en-aut-sei=Nagase en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YasuharaTakao en-aut-sei=Yasuhara en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KinKyohei en-aut-sei=Kin en-aut-mei=Kyohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SasadaSusumu en-aut-sei=Sasada en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KawauchiSatoshi en-aut-sei=Kawauchi en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YabunoSatoru en-aut-sei=Yabuno en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SugaharaChiaki en-aut-sei=Sugahara en-aut-mei=Chiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HirataYuichi en-aut-sei=Hirata en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MiyakeHayato en-aut-sei=Miyake en-aut-mei=Hayato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SasakiTatsuya en-aut-sei=Sasaki en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KawaiKoji en-aut-sei=Kawai en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=TanimotoShun en-aut-sei=Tanimoto en-aut-mei=Shun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=SaijoTomoya en-aut-sei=Saijo en-aut-mei=Tomoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 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=14 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences 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 Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=14 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Ischemic stroke kn-keyword=Ischemic stroke en-keyword=Post-stroke depression kn-keyword=Post-stroke depression en-keyword=Regenerative medicine kn-keyword=Regenerative medicine en-keyword=Rehabilitation kn-keyword=Rehabilitation en-keyword=SB623 kn-keyword=SB623 END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue= article-no= start-page=e2025-0034 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251031 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Optimal Virtual-target Definition for Detecting Feeding Arteries of Renal Cell Carcinoma Using Automated Feeder-detection Software en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose: To determine the optimal virtual-target definition for detecting renal cell carcinoma feeders using transarterial computed tomography angiography with automated feeder-detection software.
Material and Methods: This retrospective study included 17 patients with 17 renal cell carcinomas who underwent transarterial ethiodized-oil marking before cryoablation. Tumor feeders were automatically detected on transarterial renal computed tomography angiography images using the automated feeder-detection software with three virtual-target definitions: small (ellipsoidal area maximized within the tumor contour), medium (ellipsoidal area covering the entire tumor with a minimal peripheral margin), and large (ellipsoidal area including the tumor and a 5-mm peripheral margin). The detected feeders were classified as true or false positives according to the findings of selective renal arteriography, by consensus of two interventional radiologists. Feeder-detection sensitivity and the mean number of false-positive feeders per tumor were calculated for each virtual-target definition.
Results: For 17 tumors, 25 feeding arteries were identified on the arteriography. The feeder-detection sensitivity of the software was 80.0% (20/25), 88.0% (22/25), and 48.0% (12/25) for small, medium, and large virtual targets, respectively. The mean ± standard deviation number of false-positive feeders per tumor was 0.82 ± 1.3, 1.41 ± 1.1, and 2.82 ± 1.6 when using small, medium, and large virtual-target definitions, respectively.
Conclusions: The detection rate of renal cell carcinoma feeders with the automated feeder-detection software varies according to the virtual-target definition. Using a medium virtual target, covering the entire tumor with a minimal peripheral margin, may provide the highest sensitivity and an acceptable number of false-positive feeders. en-copyright= kn-copyright= en-aut-name=OkamotoSoichiro en-aut-sei=Okamoto en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=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=MunetomoKazuaki en-aut-sei=Munetomo en-aut-mei=Kazuaki 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=HigakiFumiyo en-aut-sei=Higaki en-aut-mei=Fumiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=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, Medical Development Field, Okayama University kn-affil= affil-num=2 en-affil=Department of Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Radiology, Tsuyama Chuo Hospital kn-affil= affil-num=4 en-affil=Department of Radiology, Medical Development Field, Okayama University kn-affil= affil-num=5 en-affil=Department of Radiology, Medical Development Field, Okayama University kn-affil= affil-num=6 en-affil=Department of Radiology, Medical Development Field, Okayama University kn-affil= affil-num=7 en-affil=Department of Radiology, Medical Development Field, Okayama University kn-affil= affil-num=8 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=computed tomography angiography kn-keyword=computed tomography angiography en-keyword=kidney kn-keyword=kidney en-keyword=software kn-keyword=software en-keyword=therapeutic embolization kn-keyword=therapeutic embolization END start-ver=1.4 cd-journal=joma no-vol=71 cd-vols= no-issue=11 article-no= start-page=938 end-page=943 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250402 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Mechanical Subpulmonary Support in Fontan Circulation: A Juvenile Porcine Experimental Model en-subtitle= kn-subtitle= en-abstract= kn-abstract=Mechanical cavopulmonary assist (CPA) remains challenging for failing Fontan circulation. This study aimed to evaluate the hemodynamic impact of partial CPA using a juvenile porcine model. Six pigs (30 kg) underwent the Fontan procedure using a handmade Y-shaped graft. Total CPA was established by assisting both superior vena cava (SVC) and inferior vena cava (IVC) flow to the pulmonary artery, whereas partial CPA assisted only IVC flow using a centrifugal pump. Cavopulmonary assist flow was set to 100%, 50%, or 25% of pre-Fontan cardiac output (CO). Hemodynamics at baseline, after total CPA, and after partial CPA were compared using paired t-tests. Total CPA with 100% CO support increased CO and reduced SVC and IVC pressures compared to baseline (CO, 1.03 vs. 2.36 L/min; SVC pressure, 16.3 vs. 9.5 mm Hg; IVC pressure, 17.3 vs. 9.3 mm Hg, p < 0.05 for all). Partial CPA with 25% CO support increased CO and decreased IVC pressure, though SVC pressure increased (CO, 1.03 vs. 1.52 L/min; SVC pressure, 16.3 vs. 20.5 mm Hg; IVC pressure, 17.3 vs. 11.5 mm Hg, p < 0.05 for all). Although total CPA achieved optimal hemodynamics, partial CPA with 25% CO flow was effective, suggesting a feasible, noninvasive solution for patients with failing Fontan physiology. en-copyright= kn-copyright= en-aut-name=SakodaNaoya en-aut-sei=Sakoda en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KobayashiYasuyuki en-aut-sei=Kobayashi en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=EdakiDaichi en-aut-sei=Edaki en-aut-mei=Daichi 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=KotaniYasuhiro en-aut-sei=Kotani en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=From the 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=From the 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=From the Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences and Okayama University Hospital kn-affil= affil-num=4 en-affil=From the 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=From the Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences and Okayama University Hospital kn-affil= END start-ver=1.4 cd-journal=joma no-vol=47 cd-vols= no-issue=1 article-no= start-page=95 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250311 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A case of a large venous ring around the mandibular condyle en-subtitle= kn-subtitle= en-abstract= kn-abstract=Anatomical details regarding venous drainage of the head and neck are an important matter for surgeons to avoid unnecessary complications such as hemorrhage. This report describes a case of the large venous ring around the mandibular condyle found in the cadaver. The left maxillofacial region of a latex-injected embalmed male cadaver (82 years of age at death) was dissected. The large two maxillary veins ran lateral to the capsule and superior to the mandibular notch and coursed posteroinferiorly to merge, and one trunk was formed at the posterior border of the ramus. It then received the superficial temporal vein superiorly to form the retromandibular vein (RMV). In addition, three maxillary veins were drained from the pterygoid venous plexus (PVP), medial to the ramus, one maxillary vein drained from the PVP into the RMV trunk, while two maxillary veins drained from the PVP into the anterior division of the RMV. All five large veins lateral and medial to the condyle drained from the PVP into the RMV. The knowledge of such an anatomical variation might prevent intraoperative bleeding in the temporomandibular joint region. en-copyright= kn-copyright= en-aut-name=NishiKeitaro en-aut-sei=Nishi en-aut-mei=Keitaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkuiTatsuo en-aut-sei=Okui en-aut-mei=Tatsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=KusukawaJingo en-aut-sei=Kusukawa en-aut-mei=Jingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TubbsR.

This study aimed to evaluate the impact of computed tomography-assessed sarcopenia (CT–SP) on the clinical severity and hospitalization duration of odontogenic deep neck infections (DNIs). Total of 119 patients admitted for odontogenic DNI treatment were included. Patients were divided into two groups by DNI clinical severity (severe or mild) and the patients' characteristics, including CT–SP based on skeletal muscle index (SMI), were compared between two groups. Multivariable logistic regression analysis was performed to identify independent risk factors for severe DNI. The correlation between SMI and hospitalization duration was assessed using Spearman’s rank correlation coefficient. Of the 119 patients, 60 (50.4%) presented with severe DNIs, including deep neck abscesses and necrotizing soft tissue infections. After adjusting for potential confounders, multivariable analysis identified CT–SP as the sole independent risk factor associated with severe DNI (Odds Ratio = 3.04; 95% Confidence Interval, 1.20–7.71; p = 0.019). Furthermore, SMI demonstrated a significant, weak negative correlation with the hospitalization duration (r = − 0.331, p < 0.001). CT–SP is a powerful, independent risk factor associated with severity in patients with odontogenic DNIs. This finding underscores the critical role of systemic host factors in the clinical course of maxillofacial infections and highlights the potential of opportunistic CT screening as a factor to consider in risk stratification in this vulnerable population. en-copyright= kn-copyright= en-aut-name=KikutaShogo en-aut-sei=Kikuta en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IwataEiji en-aut-sei=Iwata en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=KobayashiChizuru en-aut-sei=Kobayashi en-aut-mei=Chizuru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KimuraHiroki en-aut-sei=Kimura en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KinisadaYuki en-aut-sei=Kinisada en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TachibanaAkira en-aut-sei=Tachibana en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KusukawaJingo en-aut-sei=Kusukawa en-aut-mei=Jingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=AkashiMasaya en-aut-sei=Akashi en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 ORCID= affil-num=1 en-affil=Dental and Oral Medical Center, Kurume University School of Medicine kn-affil= affil-num=2 en-affil=Department of Oral and Maxillofacial Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Oral and Maxillofacial Radiology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Department of Oral and Maxillofacial Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Department of Oral and Maxillofacial Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of Oral and Maxillofacial Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Department of Oral and Maxillofacial Surgery, Kakogawa Central City Hospital kn-affil= affil-num=8 en-affil=Dental and Oral Medical Center, Kurume University School of Medicine kn-affil= affil-num=9 en-affil=Department of Oral and Maxillofacial Surgery, Kobe University Graduate School of Medicine kn-affil= affil-num=10 en-affil=Department of Oral and Maxillofacial Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= en-keyword=CT-assessed sarcopenia kn-keyword=CT-assessed sarcopenia en-keyword=Odontogenic deep neck infections kn-keyword=Odontogenic deep neck infections en-keyword=Severity kn-keyword=Severity en-keyword=Hospitalization duration kn-keyword=Hospitalization duration en-keyword=Skeletal muscle index kn-keyword=Skeletal muscle index END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=11 article-no= start-page=1446 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251109 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Development of Propofol-Encapsulated Liposomes and the Effect of Intranasal Administration on Bioavailability in Rabbits en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: Propofol is frequently used as an intravenous anesthetic and is rapidly metabolized. Therefore, if it could be administered non-invasively (e.g., orally) as premedication, it might hasten emergence from anesthesia, thereby improving patient safety. However, it undergoes extensive first-pass metabolism in the liver and intestines, limiting the route for premedication. We evaluated whether intranasal delivery of a propofol-encapsulated liposome solution improves systemic exposure and bioavailability in rabbits. Methods: A propofol-encapsulated liposome solution was administered to rabbits via the intravenous, oral, and intranasal routes. Blood propofol concentrations were measured for up to 60 min after administration and the area under the concentration–time curve (AUC0–60) and bioavailability of the propofol-encapsulated liposome solution were compared with those of the non-encapsulated propofol formulation. The differences were tested by two-way analysis of variance (ANOVA) with Šidák’s post hoc multiple-comparisons test and the Mann–Whitney test (α = 0.05). Results: The AUC0–60 for blood propofol concentrations after intravenous administration was significantly higher with the propofol-encapsulated liposome solution than with the non-encapsulated propofol formulation (3038.8 ± 661.5 vs. 1929.8 ± 58.2 ng·min/mL; p = 0.0286). By contrast, no increase in blood propofol concentrations was observed after oral administration, whereas intranasal administration increased blood propofol concentrations and yielded significantly higher bioavailability compared with the non-encapsulated propofol formulation (16.4 ± 7.3% vs. 2.0 ± 1.2%; p = 0.0286). Conclusions: The findings of the present study suggest that intranasal liposomal propofol increased systemic availability compared with a non-encapsulated formulation, supporting further evaluation as a candidate premedication approach for propofol. en-copyright= kn-copyright= en-aut-name=UjitaHitomi en-aut-sei=Ujita en-aut-mei=Hitomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HiguchiHitoshi en-aut-sei=Higuchi en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishiokaYukiko en-aut-sei=Nishioka en-aut-mei=Yukiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyakeSaki en-aut-sei=Miyake en-aut-mei=Saki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SatoRiko en-aut-sei=Sato en-aut-mei=Riko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyawakiTakuya en-aut-sei=Miyawaki en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Dental Anesthesiology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Dental Anesthesiology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Dental Anesthesiology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Dental Anesthesiology and Special Care Dentistry, Okayama University Graduate of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Dental Anesthesiology and Special Care Dentistry, Okayama University Graduate of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Dental Anesthesiology and Special Care Dentistry, Okayama University Graduate of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=liposome kn-keyword=liposome en-keyword=propofol kn-keyword=propofol en-keyword=bioavailability kn-keyword=bioavailability en-keyword=intranasal administration kn-keyword=intranasal administration END start-ver=1.4 cd-journal=joma no-vol=57 cd-vols= no-issue=2 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251125 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=裏表紙・英文目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=57 cd-vols= no-issue=2 article-no= start-page=93 end-page=107 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251125 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Die Agrarstruktur in Sachsen im 19.

It seeks to critically examine the limitations of traditional consumer behavior models that no longer adequately capture contemporary consumption patterns.
 Representative models such as AIDMA, AISAS, and SIPS demonstrated explanatory power within the technological and media contexts of their respective eras. However, in the current environment, where AI and algorithms not only deliver information but also shape the structure of choice, these models—built on the assumptions of linearity and rationality, are becoming increasingly insufficient.
 This paper provides a comprehensive overview of the theoretical evolution of consumer behavior models from the Mass Media Era to the Age of AI Coexistence. It highlights key limitations, including the neglect of nonlinearity; underestimation of emotional dimensions, such as empathy and resonance; and lack of theoretical responsiveness to the structural constraints imposed by algorithmic environments. Ultimately, this study serves as a theoretical starting point for a paradigm shift in consumer understanding, laying the groundwork for the future reconstruction of theory and he development of innovative marketing strategies in the age of intelligent systems. en-copyright= kn-copyright= en-aut-name=ShazadigulSawut en-aut-sei=Shazadigul en-aut-mei=Sawut kn-aut-name=夏扎提古丽沙吾提 kn-aut-sei=夏扎提古丽 kn-aut-mei=沙吾提 aut-affil-num=1 ORCID= affil-num=1 en-affil=Faculty of Humanities and Social Sciences, Okayama University kn-affil= en-keyword=Artificial Intelligence (AI) kn-keyword=Artificial Intelligence (AI) en-keyword=Consumer Behavior kn-keyword=Consumer Behavior en-keyword=Algorithm kn-keyword=Algorithm en-keyword=Decision-making kn-keyword=Decision-making en-keyword=Digital Marketing kn-keyword=Digital Marketing en-keyword=Social Media kn-keyword=Social Media END start-ver=1.4 cd-journal=joma no-vol=57 cd-vols= no-issue=2 article-no= start-page=31 end-page=47 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251125 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Reasons why gains or losses from the transfer of monetary claims are classified as miscellaneous income: Is it because it corresponds to interest rate, or is it to deal with the problems associated with the treatment of bad debt losses kn-title=金銭債権の譲渡による損益が雑所得に区分される理由―金利に該当するからなのか,それとも貸倒損失処理に伴う問題への対処なのか― en-subtitle= kn-subtitle= en-abstract= Gains or losses from the transfer of monetary claims are excluded from the assets that are the basis of transfer income under Basic Income Tax Instruction 33-1. For as long as 50 years, the Tax Authority has offered two different explanations for this exclusion:(1)“This is because gains from the transfer of monetary claims are interest rate.” and(2)“This is to address the unreasonableness of receiving tax benefits by treating losses from the transfer of monetary claims as bad debt losses,”
 This paper compares these two different explanations by the Tax Authority and shows that the better explanation is(2)“This is to address the unreasonableness of receiving tax benefits by treating losses from the transfer of monetary claims as bad debt losses.”
 In addition, because of fundamental doubts about the explanation that “gains from the transfer of monetary claims are interest rate,” this paper conducts an in-depth study of this point and clarify that this explanation is not appropriate. kn-abstract= 金銭債権の譲渡による損益は,所得税基本通達33-1により譲渡所得の基因となる資産から除外される。この理由について課税当局は50年もの長きにわたり,①「金銭債権の譲渡による利益は金利に該当するからである」,との説明と,②「金銭債権の譲渡による損失を貸倒処理して税制上の恩典を受けることから生ずる不合理に対処するためである」,とする2つの異なる説明を行ってきている。
 本稿は課税当局によるこの2つの説明の比較検討を行い,②の「金銭債権の譲渡による損失を貸倒処理して税制上の恩典を受けることから生ずる不合理に対処するためである」,との説明の方がより優れていることを明らかにするものである。

 In interactive art appreciation, viewers engage in collaborative dialogue with the artwork and other viewers, and are influenced by the promotion of creativity and improvement of the quality of the dialogue through the intervention of facilitation. This introduces an otherness that is different from the self, which creates a deviation from existing interpretations. This discrepancy in interpretation brings about a conceptual shift in the viewer, resulting in the creation of a new theory; this newly created theory eventually becomes the existing theory, and once again a collaborative dialogue takes place, giving birth to a new theory.
 In this cyclical process of creativity in interactive art appreciation, knowledge is created and accumulated, and existing knowledge is creatively destroyed to reconstruct new knowledge. Learning takes place through mutual learning mediated by intrinsic motivation, and eventually learning takes place to arrive at new interpretations, although sometimes learning support is handed over from the facilitator to the viewers. For viewers whose abilities to create meaning and grasp value are underdeveloped, interactive art appreciation helps to encourage this development, and it has the potential to have a ripple effect on development not only in art but also in the broader realm of everyday knowledge outside of art. en-copyright= kn-copyright= en-aut-name=MiyazakiSatoru en-aut-sei=Miyazaki en-aut-mei=Satoru kn-aut-name=宮崎悟 kn-aut-sei=宮崎 kn-aut-mei=悟 aut-affil-num=1 ORCID= en-aut-name=TeramotoShizuka en-aut-sei=Teramoto en-aut-mei=Shizuka kn-aut-name=寺元静香 kn-aut-sei=寺元 kn-aut-mei=静香 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学学術研究院社会文化科学学域 affil-num=2 en-affil= kn-affil=公益財団法人大原芸術財団大原芸術研究所・大原美術館 END start-ver=1.4 cd-journal=joma no-vol=57 cd-vols= no-issue=2 article-no= start-page=1 end-page=16 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251125 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Social Loss of Care Leavers: Update and Transition kn-title=介護離職の社会的損失―アップデートと時系列推移― en-subtitle= kn-subtitle= en-abstract= kn-abstract= Kishida(2020)estimated the number of labor force exiters unemployed due to family care and their lost income. We updated the result of Kishida(2020)and modified the estimation method of the lost income. We defined labor force exiters as those who were out of work 2 years after they exited. The results using the latest Employment Status Survey for 2022 are as follow. Among the 10.6 thousand annual care leavers, 35.9% restarted work and the remaining 64.1% exited the labor market. Three-fourths of returned to the exiters were non-regular workers. Among the care leavers previously in regular employment who returned to the labor market, 34.4% of them restarted work as regular workers and the remainder restarted work as non-regular workers. Among the exiters, the ratio of care leavers to all exiters was 3.8% . More than 10% of women exiters of 40-50 years of age were care leavers. Hence, the loss of middle-aged employment due to care leavers is significant.
 The wages of care leavers' previous jobs are indispensable for calculating the loss of income. However, our data did not contain the necessary information. Hence, as a proxy variable, we used the wages of workers whose attributes are similar to the ones of the care leavers. Additionally, in the loss of income calculation, we considered the income accrued from restarting work.
 The total loss of income during one year after care leave was 187.4 billion yen. We decomposed the income loss into the loss incurred by being unemployed and the loss incurred by getting a job that pays less than the previous one. The former loss was 77.1% and the latter one was 22.9% . Approximately 70% of the income loss due to wage declines was due to previous full-time employment, and 86.3% of that was due to resuming work as non-full-time employment with significantly lower wages. If the separation period lasts for more than one year, the income loss for society as a whole is the sum of the income losses in the years when the separation period is different. Based on our calculations, the annual income loss was at least 403.2 billion yen.
 The number of people leaving the labor market was 74,400 in 2012, 63,700 in 2017, and 68,100 in 2022. In 2012, when the unemployment rate was high, the return to work rate was lower than in 2017 and 2022, and the number of people leaving the labor market was relatively high. Income losses were 382.1 billion yen in 2012, 363.9 billion yen in 2017, and 399.2 billion yen in 2022. The breakdown of income losses by cause was roughly the same. en-copyright= kn-copyright= en-aut-name=KishidaKensaku en-aut-sei=Kishida en-aut-mei=Kensaku kn-aut-name=岸田研作 kn-aut-sei=岸田 kn-aut-mei=研作 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=57 cd-vols= no-issue=2 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251125 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=表紙・目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= 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=20250807 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Performance Assessment of ChatGPT for the Board Qualification Examination of the Japanese Society for Oral and Maxillofacial Radiology en-subtitle= kn-subtitle= en-abstract= kn-abstract=The aim of this study is to assess the performance and utility of ChatGPT for the board qualification examination of the Japanese Society for Oral and Maxillofacial Radiology (JSOMR). We assessed ChatGPT responses to 149 multiple-choice questions written in Japanese for the board qualification examination of the JSOMR for the 3 years from 2020 to 2022. The questions were directly entered into ChatGPT-3.5 and ChatGPT-4 models manually one by one as a prompt. The accuracy rate was calculated and classified by year, type of multiple-choice question, and level of intellectual ability, and significant differences were noted. The accuracy rate of GPT-3.5 for the 3 years was 45.0% (51.0% for 2020, 34.0% for 2021, and 50.0% for 2022), while the accuracy rate of GPT-4 was 68.5% (73.5% for 2020, 62.0% for 2021, and 70.0% for 2022) for the board qualification examination of the JSOMR. GPT-4 had a significantly higher accuracy rate than GPT-3.5 in each year. On performance classified by the type of multiple-choice questions, GPT-4 performed significantly better than GPT-3.5. However, neither model performed well with questions that required interpretation or knowledge of Japanese law. The performance of GPT-4 was significantly superior to GPT-3.5 in the board qualification examination of the JSOMR, suggesting that the use of Chat GPT, especially ChatGPT-4, would be effective as a tool for learning and preparing for the examination. en-copyright= kn-copyright= en-aut-name=TakeshitaYohei en-aut-sei=Takeshita en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawazuToshiyuki en-aut-sei=Kawazu en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=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=FujikuraMamiko en-aut-sei=Fujikura en-aut-mei=Mamiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NambaYuri en-aut-sei=Namba en-aut-mei=Yuri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YoshidaSuzuka en-aut-sei=Yoshida en-aut-mei=Suzuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YoshidaSaori en-aut-sei=Yoshida en-aut-mei=Saori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YanagiYoshinobu en-aut-sei=Yanagi en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 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 and Maxillofacial Radiology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Oral and Maxillofacial Radiology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Oral and Maxillofacial Radiology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Oral and Maxillofacial Radiology, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Oral and Maxillofacial Radiology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Preliminary Examination Room, Okayama University Hospital kn-affil= affil-num=9 en-affil=Preliminary Examination Room, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Oral and Maxillofacial Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=ChatGPT kn-keyword=ChatGPT en-keyword=GPT-3.5 kn-keyword=GPT-3.5 en-keyword=GPT-4 kn-keyword=GPT-4 en-keyword=Generative AI kn-keyword=Generative AI en-keyword=Large language model kn-keyword=Large language model en-keyword=Japanese Society for Oral and Maxillofacial Radiology kn-keyword=Japanese Society for Oral and Maxillofacial Radiology END start-ver=1.4 cd-journal=joma no-vol=23 cd-vols= no-issue=43 article-no= start-page=9936 end-page=9941 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=Harnessing the reactivity of captodative radicals: photocatalytic α-pyridination of glycyl derivatives through reversible radical coupling en-subtitle= kn-subtitle= en-abstract= kn-abstract=Captodative radicals that are highly stabilized by the presence of both electron-donating and electron-withdrawing groups exhibit unique reactivity in organic syntheses. These radicals are known to be less reactive towards radical–radical coupling reactions due to the presence of a shielding occupied molecular orbital.

An aromatization is incorporated as the driving force after a reversible radical–radical coupling process. This method can be applied to a wide variety of peptides, providing pharmaceutically relevant pyridyl-functionalized products under mild reaction conditions. en-copyright= kn-copyright= en-aut-name=YamazakiKen en-aut-sei=Yamazaki en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AkimotoShuta en-aut-sei=Akimoto en-aut-mei=Shuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiuraTomoya en-aut-sei=Miura en-aut-mei=Tomoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Division of Applied Chemistry, Okayama University kn-affil= affil-num=2 en-affil=Division of Applied Chemistry, Okayama University kn-affil= affil-num=3 en-affil=Division of Applied Chemistry, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=1 article-no= start-page=127 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250315 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinical predictors of extubation failure in postoperative critically ill patients: a post-hoc analysis of a multicenter prospective observational study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Postoperative patients constitute majority of critically ill patients, although factors predicting extubation failure in this group of patients remain unidentified. Aiming to propose clinical predictors of reintubation in postoperative patients, we conducted a post-hoc analysis of a multicenter prospective observational study.
Methods This study included postoperative critically ill patients who underwent mechanical ventilation for > 24 h and were extubated after a successful 30-min spontaneous breathing trial. The primary outcome was reintubation within 48 h after extubation, and clinical predictors for reintubation were investigated using logistic regression analyses.
Results Among the 355 included patients, 10.7% required reintubation. Multivariable logistic regression identified that the number of endotracheal suctioning episodes during the 24 h before extubation and underlying respiratory disease or pneumonia occurrence were significantly associated with reintubation (adjusted odds ratio [OR] 1.11, 95% confidence interval [CI] 1.05–1.18, p < 0.001; adjusted OR 2.58, 95%CI 1.30–5.13, p = 0.007). The probability of reintubation was increased significantly with the higher frequency of endotracheal suctioning, as indicated by restricted cubic splines. Subgroup analysis showed that these predictors were consistently associated with reintubation regardless of the use of noninvasive respiratory support after extubation.
Conclusions Endotracheal suctioning frequency and respiratory complications were identified as independent predictors of reintubation. These readily obtainable predictors may aid in decision-making regarding the extubation of postoperative patients. en-copyright= kn-copyright= en-aut-name=HattoriJun en-aut-sei=Hattori en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaAiko en-aut-sei=Tanaka en-aut-mei=Aiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KosakaJunko en-aut-sei=Kosaka en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HiraoOsamu en-aut-sei=Hirao en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FurushimaNana en-aut-sei=Furushima en-aut-mei=Nana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MakiYuichi en-aut-sei=Maki en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KabataDaijiro en-aut-sei=Kabata en-aut-mei=Daijiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UchiyamaAkinori en-aut-sei=Uchiyama en-aut-mei=Akinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=EgiMoritoki en-aut-sei=Egi en-aut-mei=Moritoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MorimatsuHiroshi en-aut-sei=Morimatsu en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MizobuchiSatoshi en-aut-sei=Mizobuchi en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KotakeYoshifumi en-aut-sei=Kotake en-aut-mei=Yoshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=ShintaniAyumi en-aut-sei=Shintani en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=KoyamaYukiko en-aut-sei=Koyama en-aut-mei=Yukiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=YoshidaTakeshi en-aut-sei=Yoshida en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=FujinoYuji en-aut-sei=Fujino en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= affil-num=1 en-affil=Faculty of Medicine, Osaka University kn-affil= affil-num=2 en-affil=Department of Anesthesiology and Intensive Care Medicine, Osaka University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Anesthesiology, Osaka General Medical Center kn-affil= affil-num=5 en-affil=Department of Anesthesiology and Intensive Care Medicine, Kobe University Hospital kn-affil= affil-num=6 en-affil=Department of Anesthesiology, Toho University Ohashi Medical Center kn-affil= affil-num=7 en-affil=Center for Mathematical and Data Science, Kobe University kn-affil= affil-num=8 en-affil=Department of Anesthesiology and Intensive Care Medicine, Osaka University Graduate School of Medicine kn-affil= affil-num=9 en-affil=Department of Anesthesia, Kyoto University Hospital kn-affil= affil-num=10 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Anesthesiology and Intensive Care Medicine, Kobe University Hospital kn-affil= affil-num=12 en-affil=Department of Anesthesiology, Toho University Ohashi Medical Center kn-affil= affil-num=13 en-affil=Department of Medical Statistics, Graduate School of Medicine, Osaka Metropolitan University kn-affil= affil-num=14 en-affil=Department of Anesthesiology and Intensive Care Medicine, Osaka University Graduate School of Medicine kn-affil= affil-num=15 en-affil=Department of Anesthesiology and Intensive Care Medicine, Osaka University Graduate School of Medicine kn-affil= affil-num=16 en-affil=Department of Anesthesiology and Intensive Care Medicine, Osaka University Graduate School of Medicine kn-affil= en-keyword=Reintubation kn-keyword=Reintubation en-keyword=Extubation failure kn-keyword=Extubation failure en-keyword=Endotracheal suctioning kn-keyword=Endotracheal suctioning en-keyword=Postoperative patient kn-keyword=Postoperative patient en-keyword=Clinical predictor kn-keyword=Clinical predictor en-keyword=Critical care kn-keyword=Critical care 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=20250924 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=DSOK-0011 Potentially Regulates Circadian Misalignment and Affects Gut Microbiota Composition in Activity-Based Anorexia Model en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: Anorexia nervosa (AN) is a metabolic-psychiatric disorder characterized by severe weight loss, hypercortisolemia, and hypothalamic–pituitary–adrenal (HPA) axis activation. In this study, we investigated the effect of inhibiting cortisol regeneration via the enzyme 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) on the pathophysiology of AN.
Method: Female C57BL/6J mice underwent a 7-day activity-based anorexia (ABA) paradigm, involving 3 h daily feeding and free access to wheels, until 25% body weight loss or experiment completion. Mice were orally treated once daily with a potent 11β-HSD1 inhibitor, DSOK-0011, or vehicle. Body weight, food intake, and activity transitions were recorded; plasma corticosterone and cholesterol levels were measured using a fluorometric assay; gut microbiota were analyzed using 16S rRNA sequencing; and hippocampal glial cells were analyzed using immunohistochemistry.
Results: DSOK-0011-treated mice exhibited a modest but significant increase in postprandial wheel-running activity compared to baseline (4–5 p.m., p = 0.018; 5–6 p.m., p = 0.043), whereas vehicle-treated mice showed higher preprandial activity (9–10 a.m., p = 0.0229). Gut microbiota analysis revealed increased alpha diversity in ABA mice, with a specific enrichment of the Lachnospiraceae family in the DSOK-0011 group. However, DSOK-0011 did not significantly affect body weight, food intake, corticosterone, and lipid levels, or hippocampal glial cell populations.
Conclusion: Inhibition of 11β-HSD1 by DSOK-0011 was associated with microbiota alterations and subtle shifts in activity timing under energy-deficient conditions. These findings suggest that peripheral glucocorticoid metabolism may influence microbial and behavioral responses in the ABA model, although its metabolic impact appears limited in the acute phase. en-copyright= kn-copyright= en-aut-name=KawaiHiroki en-aut-sei=Kawai en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WadaNanami en-aut-sei=Wada en-aut-mei=Nanami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SakamotoShinji en-aut-sei=Sakamoto en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyazakiKenji en-aut-sei=Miyazaki en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatoTaro en-aut-sei=Kato en-aut-mei=Taro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HoriuchiYoshihiro en-aut-sei=Horiuchi en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KiriiHiroshi en-aut-sei=Kirii en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NguyenHoang Duy en-aut-sei=Nguyen en-aut-mei=Hoang Duy kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HinotsuKenji en-aut-sei=Hinotsu en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OhyaYoshio en-aut-sei=Ohya en-aut-mei=Yoshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=AsadaTakahiro en-aut-sei=Asada en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=YokodeAkiyoshi en-aut-sei=Yokode en-aut-mei=Akiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 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=13 ORCID= en-aut-name=MiyazakiHaruko en-aut-sei=Miyazaki en-aut-mei=Haruko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 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=15 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=16 ORCID= affil-num=1 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences 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=Sumitomo Pharma Co.

Notably, blocking β1 receptors can lead to organ protection through anti‑inflammatory and anti‑apoptotic effects. Additionally, although the β1 receptor pathway is blocked by the β1 blocker, the β2 receptor pathway may be preserved and activate the 5' adenosine monophosphate‑activated protein kinase (AMPK) pathway. The present study aimed to examine whether administration of the β1 blocker landiolol could achieve lung protection in a model of HSR‑ALI, alongside improvements in inflammation and apoptosis. Male Sprague‑Dawley rats underwent hemorrhage keeping their mean arterial pressure at 30 mmHg for 1 h. Resuscitation by reinfusion was initiated to restore blood pressure to pre‑hemorrhage levels for >15 min, followed by a 45‑min stabilization period to create the HSR‑ALI model. Landiolol (100 mg/kg/min) or saline was continuously administered after resuscitation. The lung tissues, which were collected for assessing inflammation and apoptosis‑related damage, underwent analyses, including histological examination, neutrophil count, assessment of lung wet/dry weight ratio, detection of the mRNA levels of tumor necrosis factor‑α (TNF‑α) and inducible nitric oxide synthase (iNOS), identification of terminal deoxynucleotidyl transferase dUTP nick‑end labeling (TUNEL)‑positive cells, and evaluation of caspase‑3 expression. In addition, phosphorylated AMPKα (pAMPKα) expression was tested via western blotting. Compared with the HSR/saline group, the HSR/landiolol group demonstrated a reduction in lung tissue damage score, and significant reductions in neutrophil count, lung wet/dry weight ratio, lung TNF‑α and iNOS mRNA levels, TUNEL‑positive cells and cleaved caspase‑3 expression. Furthermore, landiolol administration following HSR treatment increased pAMPKα expression. No significant hypotension occurred between the HSR/landiolol and HSR/saline groups; and blood loss did not differ significantly between the groups. In conclusion, landiolol administration after HSR reduced lung inflammation and apoptosis, suggesting a potential improvement in tissue damage. Furthermore, pAMPKα activation in the HSR/landiolol group may be the mechanism underlying the pulmonary protective effects of landiolol. en-copyright= kn-copyright= en-aut-name=SakamotoRisa en-aut-sei=Sakamoto en-aut-mei=Risa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShimizuHiroko en-aut-sei=Shimizu en-aut-mei=Hiroko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakamuraRyu en-aut-sei=Nakamura en-aut-mei=Ryu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=LuYifu en-aut-sei=Lu en-aut-mei=Yifu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=LiYaqiang en-aut-sei=Li en-aut-mei=Yaqiang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OmoriEmiko en-aut-sei=Omori en-aut-mei=Emiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakahashiToru en-aut-sei=Takahashi en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MorimatsuHiroshi en-aut-sei=Morimatsu en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Anesthesiology and Resuscitology, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Medical School kn-affil= affil-num=3 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Medical School kn-affil= affil-num=4 en-affil=Department of Human Anatomy, Shantou University Medical College kn-affil= affil-num=5 en-affil=Department of Anesthesiology and Resuscitology, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Anesthesiology and Resuscitology, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Anesthesiology, Okayama Saidaiji Hospital kn-affil= affil-num=8 en-affil=Department of Anesthesiology and Resuscitology, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=HSR kn-keyword=HSR en-keyword=lung injury kn-keyword=lung injury en-keyword=landiolol kn-keyword=landiolol en-keyword=β1 blocker kn-keyword=β1 blocker en-keyword=inflammation kn-keyword=inflammation en-keyword=apoptosis kn-keyword=apoptosis END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=1 article-no= start-page=59 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251022 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Venous air embolism induced by burr hole drilling before dural incision in craniotomy: two case reports en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Venous air embolism (VAE) is a rare but potentially fatal complication in neurosurgery typically caused by injury to dura mater, especially venous sinuses, during craniotomy. We report two cases of VAE that occurred before dural incision.
Case presentation: Both patients underwent craniotomy under general anesthesia in a head-up position. Hemodynamic and respiratory deterioration occurred during or immediately after burr hole drilling with abnormal vital signs and transesophageal echocardiography findings, raising suspicion for VAE. Immediate management, including surgical field protection and cardiopulmonary support, stabilized the patients’ conditions. The procedure was subsequently discontinued in case 1 and modified to limited resection in case 2. Postoperative computed tomography revealed intracranial venous air within the internal jugular vein, cavernous sinus, and diploic veins.
Conclusion: These cases highlight that VAE can occur even before dural incision. Vigilant intraoperative monitoring and prompt intervention are essential for preventing potentially fatal outcomes. en-copyright= kn-copyright= en-aut-name=MotoiYohei en-aut-sei=Motoi en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkaharaShuji en-aut-sei=Okahara en-aut-mei=Shuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TaniMakiko en-aut-sei=Tani en-aut-mei=Makiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsuboiNobushige en-aut-sei=Tsuboi en-aut-mei=Nobushige kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MorimatsuHiroshi en-aut-sei=Morimatsu en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Neurosurgery, Okayama Red Cross Hospital kn-affil= affil-num=5 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Hospital kn-affil= en-keyword=Venous air embolism kn-keyword=Venous air embolism en-keyword=Transesophageal echocardiography kn-keyword=Transesophageal echocardiography en-keyword=Computed tomography kn-keyword=Computed tomography en-keyword=Diploic veins kn-keyword=Diploic veins en-keyword=Emissary veins kn-keyword=Emissary veins en-keyword=Burr hole drilling kn-keyword=Burr hole drilling en-keyword=Case report kn-keyword=Case report 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=20250909 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Current Status of Continuous Renal Replacement Therapy in Japanese Intensive Care Units: A Multicenter Retrospective Observational Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Continuous renal replacement therapy (CRRT) is often performed for critically ill patients in intensive care units (ICUs), but its optimal indication and settings have yet to be determined. Thus, we aimed to describe the current status of CRRT in Japan through a multicenter retrospective observational study. Methods: Adult ICU patients receiving CRRT at 18 tertiary hospitals in Japan (up to 100 patients from each hospital over the past year) were retrospectively enrolled. Patients receiving CRRT for <24 h or intermittent renal replacement therapy together with CRRT were excluded. The primary outcomes were the temporal changes in the electrolyte levels, acid-base balance, and uremia-related small solute concentrations. The secondary outcomes included potassium (K) and phosphate (P) supplementations during CRRT. Results: Altogether, 1,045 patients were enrolled. The median CRRT duration and dose were 4.4 days and 17.3 mL/kg/h, respectively. The electrolyte levels, acid-base balance, and uremia-related small solute concentrations returned to normal by day 4 of treatment. A total of 732 (70.0%) patients received K supplementation, and only a few patients had hypokalemia until day 5. Moreover, 414 (39.6%) patients received P supplementation, and approximately 30%–50% of the patients had hypophosphatemia until day 5. Conclusion: The CRRT dose in Japan was lower than that was recommended by the Kidney Disease: Improving Global Outcomes guideline. The electrolyte level abnormalities and acid-base imbalances of the studied patients were improved within 72–96 h of CRRT. Contrarily, K and P supplementations were common, indicating that the current CRRT solutions need to be modified. en-copyright= kn-copyright= en-aut-name=NakanoHidehiko en-aut-sei=Nakano

patients treated with spinal cord stimulation for herpes zoster-associated pain: a retrospective case–control study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose In patients with herpes zoster-associated pain (ZAP), magnetic resonance imaging (MRI) has revealed T2 high-signal intensity zones (MRI T2 HIZ) in the dorsal horn of the spinal cord, associated with postherpetic neuralgia (PHN). We retrospectively analyzed the relationship between PHN and MRI T2 HIZ in patients with refractory ZAP in the subacute phase who underwent temporary spinal cord stimulation therapy (tSCS).
Methods This single-center, case–control study included patients who underwent tSCS for refractory ZAP between 2010 and 2018. MRIs were re-assessed for the presence of T2 HIZ in the dorsal horn of the spinal cord. Patients were divided into T2 HIZ( +) and T2 HIZ(−) groups. Patients with a numerical rating score (NRS) ≥ 3 at the last visit were defined as PHN. The NRS values and the incidence rate of PHN were compared between the two groups.
Results Of the 67 cases extracted, 38 were included in the analysis: 22 in T2 HIZ( +) group and 16 in T2 HIZ(−) group. No significant differences were observed in background factors between the two groups. However, the T2 HIZ( +) group had a significantly higher NRS at the final visit (T2 HIZ( +):3.8 ± 2.1, T2 HIZ(−):1.4 ± 1.5; P < 0.05) and had significantly more patients with PHN than the T2 HIZ(−) group (T2 HIZ( +) vs. T2 HIZ(−), 15/22 (68%) vs. 3/16 (19%); odds ratio = 8.67; 95% confidence interval, 1.7–63.3).
Conclusion T2HIZ is detected in more than half of refractory ZAP, and pain is more likely to remain after tSCS treatment in the T2HIZ( +) group. en-copyright= kn-copyright= en-aut-name=ArakawaKyosuke en-aut-sei=Arakawa en-aut-mei=Kyosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakagawaMasayuki en-aut-sei=Nakagawa en-aut-mei=Masayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AbeYoichiro en-aut-sei=Abe en-aut-mei=Yoichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MorimatsuHiroshi en-aut-sei=Morimatsu 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 Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pain Management Clinic, NTT Medical Center Tokyo kn-affil= affil-num=3 en-affil=Department of Pain Management Clinic, NTT Medical Center Tokyo kn-affil= affil-num=4 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Herpes zoster kn-keyword=Herpes zoster en-keyword=Magnetic resonance imaging kn-keyword=Magnetic resonance imaging en-keyword=Postherpetic neuralgia kn-keyword=Postherpetic neuralgia en-keyword=Refractory zoster-associated pain kn-keyword=Refractory zoster-associated pain en-keyword=Temporary spinal cord stimulation kn-keyword=Temporary spinal cord stimulation END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page=436 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241127 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Efficacy of Pericapsular Nerve Group (PENG) block in preoperative rehabilitation (Prehabilitation) for patients with femoral neck fractures: study protocol for a randomized, placebo-controlled, double-blinded trial en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Despite surgery intervention for femoral neck fractures is recommended within 48 h of admission, achieving timely surgery presents challenges for patients with severe comorbidities, or in resource-limited settings. Preoperative rehabilitation (prehabilitation) reduces bedridden time, enhances mobility, and improves postoperative outcomes for patients scheduled for hip arthroplasty due to femoral neck fractures. However, prehabilitation is hindered by insufficient pain control. The pericapsular nerve group (PENG) block provides effective analgesia while preserving motor function. We designed a study to assess the efficacy of PENG block in facilitating prehabilitation for patients with femoral neck fractures who are scheduled for hip arthroplasty.
Methods This prospective randomized placebo-controlled double-blinded trial aims to enroll 100 patients with Garden 3 or 4 femoral neck fractures who are scheduled for hip arthroplasty. Participants will be randomly assigned to receive a PENG block with 0.375% ropivacaine (PENG group) or with normal saline (placebo group) before the initial prehabilitation session. The prehabilitation program comprises five items: Bed-sitting, Edge-sitting, Stand-up, Maintaining-standing, and Wheelchair-transfer, performed with the assistance of a single physical therapist. The primary outcome is the percentage of patients completing the entire prehabilitation program. Secondary outcomes during the initial prehabilitation session are the achievement of each program item and the Numerical Rating Scale (NRS) pain score. Other secondary outcomes include intraoperative bleeding amounts, thromboembolic events during postoperative day 0 to 7, postoperative 3-day cumulative Cumulated Ambulation Score (CAS), and discharge destination. The postoperative outcomes will be compared between subgroups of patients undergoing surgery within 48 h of admission and those undergoing surgery more than 48 h of admission.
Discussion This is the first study aiming to assess the efficacy of PENG block in prehabilitation for patients with femoral neck fractures who are scheduled for hip arthroplasty. PENG block could be beneficial, especially for patients facing delayed surgery, providing a potential treatment option during the waiting period.

Although the benefits of preoperative rehabilitation (prehabilitation) in hip arthroplasty have been reported, pain management remains a challenge. The pericapsular nerve group (PENG) block, known for its exceptional analgesic effect and motor function preservation, may be a promising intervention during prehabilitation in these patients.
Case: We enrolled ten patients with Garden classification 3–4 femoral neck fractures scheduled for hip arthroplasty. After receiving a PENG block with 20 ml of 0.375% ropivacaine, all patients underwent initial prehabilitation sessions comprising 9 mobility levels, ranging from bed-sitting to walking. One patient was excluded due to experiencing high blood pressure during prehabilitation. Six of the nine remaining patients (66.7%) were successfully transferred from bed to wheelchair.
Conclusions: The PENG block enhanced prehabilitation for patients with femoral neck fractures undergoing hip arthroplasty. en-copyright= kn-copyright= en-aut-name=JinZhuan en-aut-sei=Jin en-aut-mei=Zhuan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SugiyamaDaisuke en-aut-sei=Sugiyama en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HigoFumiya en-aut-sei=Higo en-aut-mei=Fumiya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HirataTakahiro en-aut-sei=Hirata en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KobayashiOsamu en-aut-sei=Kobayashi en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MorimatsuHiroshi en-aut-sei=Morimatsu en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=UedaKenichi en-aut-sei=Ueda en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Anesthesiology, Kameda Medical Center kn-affil= affil-num=3 en-affil=Department of Rehabilitation, Kameda Medical Center kn-affil= affil-num=4 en-affil=Department of Rehabilitation, Kameda Medical Center kn-affil= affil-num=5 en-affil=Department of Anesthesiology, Kameda Medical Center kn-affil= affil-num=6 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Anesthesiology, Kameda Medical Center kn-affil= en-keyword=Conduction anesthesia kn-keyword=Conduction anesthesia en-keyword=Femoral neck fractures kn-keyword=Femoral neck fractures en-keyword=Hip fractures kn-keyword=Hip fractures en-keyword=Nerve block kn-keyword=Nerve block en-keyword=Prehabilitation kn-keyword=Prehabilitation en-keyword=Preoperative exercise kn-keyword=Preoperative exercise en-keyword=Preoperative rehabilitation kn-keyword=Preoperative rehabilitation en-keyword=Regional anesthesia kn-keyword=Regional anesthesia END start-ver=1.4 cd-journal=joma no-vol=215 cd-vols= no-issue= article-no= start-page=110706 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202510 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Compression only CPR and mortality in pediatric out-of-hospital cardiac arrest during COVID-19 pandemic en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: The COVID-19 pandemic influenced resuscitation practices worldwide, leading to a notable decline in rescue breathing cardiopulmonary resuscitation (RB-CPR), even in pediatric out-of-hospital cardiac arrest (OHCA). Understanding the impact of this decline is important to assess the role of rescue breathing in pediatric resuscitation. This study aimed to evaluate the impact of the reduced RB-CPR during the COVID-19 pandemic on mortality and neurological outcomes among pediatric OHCA patients in Japan.
Methods: This retrospective cohort study utilized data from the nationwide All-Japan Utstein Registry for pediatric OHCA patients (≤17 years) who received bystander CPR between January 2017 and December 2021. Data were compared in pre-COVID-19 (2017–2019) versus pandemic (2020–2021) periods. Bystander CPR were classified as RB-CPR or chest compression-only CPR (CO-CPR). The primary outcome was 30-day mortality, with secondary outcomes including the absence of return of spontaneous circulation and unfavorable neurological outcomes (Cerebral Performance Category scores of 3–5). Adjusted risk ratios (aRR) with 95 % confidence intervals (CI) were estimated using Poisson regression.
Results: Of 7,162 pediatric OHCA cases, 3,352 (46.8 %) received bystander CPR. RB-CPR decreased from 33.0 % pre-pandemic to 21.1 % during the pandemic. CO-CPR was associated with higher 30-day mortality (aRR: 1.16; 95 % CI: 1.08–1.24) and unfavorable neurological outcomes (aRR: 1.10; 95 % CI: 1.05–1.16). These trends were consistent across age groups and arrest etiologies, particularly for non-cardiac causes. More significantly, the decrease in RB-CPR was estimated to contribute to 10.7 excess deaths annually during the pandemic.
Conclusions: The findings highlight the importance of rescue breathing in pediatric OHCA. CO-CPR, while suitable for adults, may compromise outcomes in children. Emphasizing rescue breathing in pediatric resuscitation training and integrating infection control measures is essential for future public health emergencies. en-copyright= kn-copyright= en-aut-name=ObaraTakafumi en-aut-sei=Obara en-aut-mei=Takafumi 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=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=TsukaharaKohei en-aut-sei=Tsukahara en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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=6 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=7 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=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 Epidemiology, 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 Epidemiology, 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=Cardiopulmonary resuscitation kn-keyword=Cardiopulmonary resuscitation en-keyword=Out-of-hospital kn-keyword=Out-of-hospital en-keyword=Pediatrics kn-keyword=Pediatrics en-keyword=Artificial respiration kn-keyword=Artificial respiration en-keyword=COVID-19 pandemic kn-keyword=COVID-19 pandemic END start-ver=1.4 cd-journal=joma no-vol=106 cd-vols= no-issue=7 article-no= start-page=002115 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250725 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Summary of taxonomy changes ratified by the International Committee on Taxonomy of Viruses (ICTV) from the Fungal and Protist Viruses Subcommittee, 2025 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The Fungal and Protist Viruses Subcommittee (SC) of the International Committee on Taxonomy of Viruses (ICTV) has received a total of eight taxonomic proposals for the 2024 annual cycle. The extent of proposed changes varied, including nomenclatural updates, creation of new taxa and reorganization of established taxa. Following the ICTV procedures, all proposals were reviewed and voted upon by the members of the Executive Committee with ratification in March 2025. As a result, a total of 52 species in the families Botourmiaviridae and Marnaviridae were renamed to comply with the mandated binomial format. A new genus has been added to the dsRNA virus family Amalgaviridae, while two new families, Splipalmiviridae (Wolframvirales) and Mycoalphaviridae (Hepelivirales), were created to classify new groups of positive-sense (+) RNA mycoviruses. The class Arfiviricetes (Cressdnaviricota) was expanded by a new order Lineavirales and a new family Oomyviridae of ssDNA viruses. Additionally, a new class Orpoviricetes was created in the kingdom Orthornavirae to classify a group of bisegmented (+)RNA viruses reported from fungi and oomycetes. Finally, the order Pimascovirales was reorganized to better depict evolutionary relationships of pithoviruses and related viruses with large dsDNA genomes. The summary of updates in the taxonomy of fungal and protist viruses presented here is limited to taxa within the remit of this Subcommittee. For information on taxonomy changes on other fungal viruses closely related to animal and/or plant viruses, please see reports from sister ICTV Subcommittees (i.e. Plant Virus SC and Animal dsRNA and ssRNA(−) Viruses SC). en-copyright= kn-copyright= en-aut-name=SabanadzovicSead en-aut-sei=Sabanadzovic en-aut-mei=Sead kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID=

kn-article= en-subject= kn-subject= en-title= kn-title=Virus taxonomy proposal summaries: a searchable and citable resource to disseminate virus taxonomy advances en-subtitle= kn-subtitle= en-abstract= kn-abstract=Taxonomic classification of cellular organisms requires the publication of descriptions and proposed names of species and the deposition of specimens. Virus taxonomy is developed through a different system of annual submission of formal taxonomy proposals (TPs) that can be submitted by anyone but are typically prepared by a study group appointed by the International Committee on Taxonomy of Viruses (ICTV) and consisting of experts on a particular group of viruses. These are initially evaluated by an expert subcommittee and by the executive committee (EC) of the ICTV. EC-approved TPs are then submitted for evaluation and a ratification vote by the wider ICTV membership. Following ratification, the new taxonomy is annually updated in the Master Species List, associated databases and bioinformatic resources. The process is consistent, creates traceability in assignments and supports a fully evaluated, hierarchical classification and nomenclature of all taxonomic ranks from species to realms. The structure also facilitates large-scale and coordinated changes to virus taxonomy, such as the recent introduction of a binomial species nomenclature.
TPs are available on the ICTV website after ratification, but they are not indexed in bibliographic databases and are not easily cited. Authors of TPs do not receive citation credit for adopted proposals, and their voluntary contributions are largely invisible in the published literature. For greater visibility of TPs and their authors, the ICTV will commence the annual publication of summaries of all TPs from each ICTV subcommittee. These summaries will provide a searchable compendium of all annual taxonomy changes and additions as well as direct links to the Master Species List and other ICTV bioinformatic resources. Their publication will provide due credit and citations for their authors, form the basis for disseminating taxonomy decisions and promote greater visibility and accessibility to taxonomy changes for the virology community. en-copyright= kn-copyright= en-aut-name=MayneRichard en-aut-sei=Mayne en-aut-mei=Richard kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SimmondsPeter en-aut-sei=Simmonds en-aut-mei=Peter kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SmithDonald B. en-aut-sei=Smith en-aut-mei=Donald B. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AdriaenssensEvelien M. en-aut-sei=Adriaenssens en-aut-mei=Evelien M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=LefkowitzElliot J. en-aut-sei=Lefkowitz en-aut-mei=Elliot J. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OksanenHanna M. en-aut-sei=Oksanen en-aut-mei=Hanna M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ZerbiniFrancisco Murilo en-aut-sei=Zerbini en-aut-mei=Francisco Murilo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=Alfenas-ZerbiniPoliane en-aut-sei=Alfenas-Zerbini en-aut-mei=Poliane kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=AylwardFrank O en-aut-sei=Aylward en-aut-mei=Frank O kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=Freitas-AstúaJuliana en-aut-sei=Freitas-Astúa en-aut-mei=Juliana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=HendricksonR.

receiving extracorporeal cardiopulmonary resuscitation: a nationwide retrospective study (the JAAM-OHCA registry) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Few studies have examined mid-term neurological changes in out-of-hospital cardiac arrest (OHCA) patients after receiving extracorporeal cardiopulmonary resuscitation (ECPR). This study aimed to evaluate neurological improvements between 30 and 90 days in OHCA patients treated with ECPR or conventional cardiopulmonary resuscitation (CCPR) using a large nationwide cohort.
Methods: This retrospective multicenter study used data from a Japanese nationwide OHCA registry. Participants were categorized into ECPR and CCPR groups based on the initial resuscitation method. Neurological changes between 30 and 90 days were assessed using Cerebral Performance Category (CPC) scores. The primary outcome was neurological improvement, defined as an improvement in CPC score during this period.
Results: A total of 4467 OHCA survivors at 30 days were included, 669 in the ECPR group and 3798 in the CCPR group. At 30 days, favorable neurological outcomes were observed in 318 ECPR patients (47.5 %) and 2103 CCPR patients (55.4 %). Neurological improvement between 30 and 90 days was more frequent in the ECPR group (83 [12.4 %] vs. 258 [6.7 %]). There was no significant difference in 90-day mortality between the two groups (82 [12.2 %] vs. 519 [13.6 %]). ECPR was independently associated with 30- to 90-day neurological improvement (adjusted odds ratio (OR) 2.01; 95 % confidence interval (CI), 1.38–2.93) but was not associated with 90-day mortality (adjusted OR 1.11; 95 % CI, 0.77–1.59).
Conclusion: ECPR was associated with a greater likelihood of neurological improvement between 30 and 90 days. By 90 days, mortality was nearly the same in both groups. en-copyright= kn-copyright= en-aut-name=HongoTakashi en-aut-sei=Hongo en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=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=UedaYoshiyuki en-aut-sei=Ueda en-aut-mei=Yoshiyuki 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= 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=Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Department of Emergency, Critical Care, and Disaster Medicine kn-affil= affil-num=2 en-affil=Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Department of Emergency, Critical Care, and Disaster Medicine kn-affil= affil-num=3 en-affil=Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Department of Emergency, Critical Care, and Disaster Medicine kn-affil= affil-num=4 en-affil=Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Department of Emergency, Critical Care, and Disaster Medicine kn-affil= affil-num=5 en-affil=Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Department of Emergency, Critical Care, and Disaster Medicine kn-affil= affil-num=6 en-affil=Okayama University, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Department of Epidemiology kn-affil= affil-num=7 en-affil=Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Department of Emergency, Critical Care, and Disaster Medicine kn-affil= affil-num=8 en-affil=Okayama University Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Department of Emergency, Critical Care, and Disaster Medicine kn-affil= en-keyword=Post-cardiac arrest syndrome kn-keyword=Post-cardiac arrest syndrome en-keyword=Cardiac arrest kn-keyword=Cardiac arrest en-keyword=ECPR kn-keyword=ECPR en-keyword=Patient outcome assessment kn-keyword=Patient outcome assessment en-keyword=Prognostication kn-keyword=Prognostication en-keyword=Venoarterial ECMO kn-keyword=Venoarterial ECMO END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=8 article-no= start-page=e101809 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=Neurological outcomes with hypothermia versus normothermia in patients with moderate initial illness severity following resuscitation from out-of-hospital cardiac arrest: protocol for a multicentre randomised controlled trial (R-CAST OHCA) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction Temperature control is a fundamental intervention for neuroprotection following resuscitation from cardiac arrest. However, evidence regarding the efficacy of hypothermia in post-cardiac arrest syndrome (PCAS) remains unclear. Retrospective studies suggest that the clinical effectiveness of hypothermia may depend on the severity of PCAS. The R-CAST OHCA trial aims to compare the efficacy of hypothermia versus normothermia in improving 30-day neurological outcomes in patients with moderately severe PCAS following out-of-hospital cardiac arrest.
Methods and analysis The multicentre, single-blind, parallel-group, superiority, randomised controlled trial (RCT) is conducted with the participation of 35 emergency and critical care centres and/or intensive care units at academic and non-academic hospitals. The study enrols moderately severe PCAS patients, defined as those with a revised post-Cardiac Arrest Syndrome for induced Therapeutic Hypothermia score of 5.5–15.5. A target number of 380 participants will be enrolled. Participants are randomised to undergo either hypothermia or normothermia within 3 hours after return of spontaneous circulation. Patients in the hypothermia group are cooled and maintained at 34°C until 28 hours post-randomisation, followed by rewarming to 37°C at a rate of 0.25°C/hour. Patients in the normothermia group are maintained at normothermia (36.5°C–37.7°C). Total periods of intervention, including the cooling, maintenance and rewarming phases, will occur 40 hours after randomisation. Other treatments for PCAS can be determined by the treating physicians. The primary outcome is a favourable neurological outcome, defined as Cerebral Performance Category 1 or 2 at 30 days after randomisation and compared using an intention-to-treat analysis.
Ethics and dissemination This study has been approved by the Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences and Okayama University Hospital, Ethics Committee (approval number: R2201-001). Written informed consent is obtained from all participants or their authorised surrogates. Results will be disseminated via publications and presentations.

This study uncovers a sophisticated viral counter-defense mechanism in the Cryphonectria hypovirus 1 (CHV1)-Fusarium graminearum system, where the viral p29 protein subverts host redox homeostasis to overcome antiviral responses. That p29 directly interacts with and inhibits the enzymatic activity of fungal NAD(P)H-dependent FMN reductase 1 (FMR1), leading to increased ROS accumulation and subsequent autophagy activation is demonstrated. Strikingly, this ROS-induced autophagy selectively targets for degradation two core antiviral RNA silencing components against CHV1 in F. graminearum, Dicer-like 2 (DCL2) and Argonaute-like 1 (AGL1), thereby compromising the host's primary antiviral defense system. Genetic analysis confirms this coordinated hijacking of host machineries, as CHV1 shows enhanced accumulation in the FMR1 knockout and reduced accumulation in autophagy-deficient fungal strains. This work reveals a tripartite interplay among oxidative stress, autophagy, and RNA silencing that CHV1 manipulates through p29 multifunctional activity. These findings provide a model for how viruses coordinately regulate distinct host defense systems to optimize infection. en-copyright= kn-copyright= en-aut-name=ZhaiShiyu en-aut-sei=Zhai en-aut-mei=Shiyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=PangTianxing en-aut-sei=Pang en-aut-mei=Tianxing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=PengShiyu en-aut-sei=Peng en-aut-mei=Shiyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ZouShenshen en-aut-sei=Zou en-aut-mei=Shenshen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=DengZhiping en-aut-sei=Deng en-aut-mei=Zhiping kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=KangZhensheng en-aut-sei=Kang en-aut-mei=Zhensheng 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=SunLiying en-aut-sei=Sun en-aut-mei=Liying kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=State Key Laboratory of Crop Stress Biology for Arid Areas and College of Plant Protection, Northwest A&F University kn-affil= affil-num=2 en-affil=State Key Laboratory of Crop Stress Biology for Arid Areas and College of Plant Protection, Northwest A&F University kn-affil= affil-num=3 en-affil=State Key Laboratory of Crop Stress Biology for Arid Areas and College of Plant Protection, Northwest A&F University kn-affil= affil-num=4 en-affil=Department of Plant Pathology, College of Plant Protection, Shandong Agricultural University kn-affil= affil-num=5 en-affil=Institute of Virology and Biotechnology, Zhejiang Academy of Agricultural Sciences kn-affil= affil-num=6 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=7 en-affil=State Key Laboratory of Crop Stress Biology for Arid Areas and College of Plant Protection, Northwest A&F University kn-affil= affil-num=8 en-affil=State Key Laboratory of Crop Stress Biology for Arid Areas and College of Plant Protection, Northwest A&F University kn-affil= affil-num=9 en-affil=State Key Laboratory of Crop Stress Biology for Arid Areas and College of Plant Protection, Northwest A&F University kn-affil= en-keyword=argonaute kn-keyword=argonaute en-keyword=autophagic degradation kn-keyword=autophagic degradation en-keyword=cryphonectria hypovirus 1 kn-keyword=cryphonectria hypovirus 1 en-keyword=dicer kn-keyword=dicer en-keyword=reactive oxygen species kn-keyword=reactive oxygen species en-keyword=RNA silencing suppressor kn-keyword=RNA silencing suppressor END start-ver=1.4 cd-journal=joma no-vol=67 cd-vols= no-issue=1 article-no= start-page=e70258 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=Early-life exposures and child health outcomes: A narrative review of LSN21 research in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: The Longitudinal Survey of Newborns in the 21st Century (LSN21) tracks two Japanese national birth cohorts—2001 (baseline n = 47,010) and 2010 (n = 38,554)—from infancy through young adulthood, capturing parenting practices and family environments. Most studies analyze single exposures or outcomes. We conducted a narrative review summarizing the findings published by the Okayama University group on diverse health and developmental outcomes.
Methods: We reviewed 59 LSN21 papers (2013–2025), extracting data on exposures, outcomes, and methods. Evidence was categorized into four exposure types (infant feeding, sleep, environmental, and perinatal) and three outcome domains (obesity, allergies/respiratory tract infections, and neurobehavioral development), including cohort comparisons.
Results: Exclusive breastfeeding was associated with a lower obesity risk at ages 7 (adjusted odds ratio 0.55, 95% confidence interval 0.39–0.78) and 15, later puberty, and fewer hospitalizations. Short or irregular sleep before age 3 was linked to behavioral problems and injuries. Maternal smoking and prenatal air pollution were associated with respiratory conditions and developmental challenges. Preterm birth and small-for-gestational-age predicted delays, especially without catch-up growth by age 2. Pneumococcal vaccination likely contributed to declining otitis media after 2010. Additional findings included associations between outdoor play and reduced obesity risk, and complex relationships between breastfeeding and food allergies that varied by infantile eczema status.
Conclusions: LSN21 findings highlight modifiable early-life factors (breastfeeding, sleep patterns, and smoke-free environments) and identify preterm and growth-restricted children for priority monitoring. While LSN21's strength lies in longitudinal social assessments, complementary perspectives from other Japanese cohorts could enhance understanding of biological mechanisms and intergenerational effects. 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=MatsuoRumi en-aut-sei=Matsuo en-aut-mei=Rumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamamuraYuka en-aut-sei=Yamamura en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsugeTakahiro en-aut-sei=Tsuge en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=UraguchiKensuke en-aut-sei=Uraguchi en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TamaiKei en-aut-sei=Tamai en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakamuraKazue en-aut-sei=Nakamura en-aut-mei=Kazue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TakeuchiAkihito en-aut-sei=Takeuchi en-aut-mei=Akihito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 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, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences 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=Department of Epidemiology, 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 Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Division of Neonatology, NHO Okayama Medical Center kn-affil= affil-num=10 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=breastfeeding kn-keyword=breastfeeding en-keyword=child health kn-keyword=child health en-keyword=environmental exposure kn-keyword=environmental exposure en-keyword=longitudinal studies kn-keyword=longitudinal studies en-keyword=perinatal kn-keyword=perinatal END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=1 article-no= start-page=234 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251114 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Rotenone targets midbrain astrocytes to produce glial dysfunction-mediated dopaminergic neurodegeneration en-subtitle= kn-subtitle= en-abstract= kn-abstract=Exposure to pesticides, such as rotenone or paraquat, is an environmental factor that plays an important role in the pathogenesis of Parkinson's disease (PD). Rotenone induces PD-like pathology and is therefore used to develop parkinsonian animal models. Dopaminergic neurotoxicity caused by rotenone has been attributed to the inhibition of mitochondrial complex I, oxidative stress and neuroinflammation; however, the mechanisms underlying selective dopaminergic neurodegeneration by rotenone remain unclear. To resolve this, we focused on glial diversity and examined whether the brain region-specific glial response to rotenone could determine the vulnerability of dopaminergic neurons using primary cultured neurons, astrocytes and microglia from the midbrain and striatum of rat embryos and rotenone-injected PD model mice. Direct neuronal treatment with low-dose rotenone failed to damage dopaminergic neurons. Conversely, rotenone exposure in the presence of midbrain astrocyte and microglia or conditioned media from rotenone-treated midbrain glial cultures containing astrocytes and microglia produced dopaminergic neurotoxicity, but striatal glia did not. Surprisingly, conditioned media from rotenone-treated midbrain astrocytes or microglia monocultures did not affect neuronal survival. We also demonstrated that rotenone targeted midbrain astrocytes prior to microglia to induce dopaminergic neurotoxicity. Rotenone-treated astrocytes produced secreted protein acidic and rich in cysteine (SPARC) extracellularly, which induced microglial proliferation, increase in IL-1β and TNF-α, and NF-κB (p65) nuclear translocation in microglia, resulting in dopaminergic neurodegeneration. In addition, rotenone exposure caused the secretion of NFAT-related inflammatory cytokines and a reduction in the level of an antioxidant metallothionein (MT)-1 from midbrain glia. Furthermore, we observed microglial proliferation and a decrease in the number of MT-positive astrocytes in the substantia nigra, but not the striatum, of low-dose rotenone-injected PD model mice. Our data highlight that rotenone targets midbrain astrocytes, leading to SPARC secretion, which promotes the neurotoxic conversion of microglia and leads to glial dysfunction-mediated dopaminergic neurodegeneration. en-copyright= kn-copyright= en-aut-name=MiyazakiIkuko en-aut-sei=Miyazaki en-aut-mei=Ikuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IsookaNami en-aut-sei=Isooka en-aut-mei=Nami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KikuokaRyo en-aut-sei=Kikuoka en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ImafukuFuminori en-aut-sei=Imafuku en-aut-mei=Fuminori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MasaiKaori en-aut-sei=Masai en-aut-mei=Kaori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TomimotoKana en-aut-sei=Tomimoto en-aut-mei=Kana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SakaguchiMasakiyo en-aut-sei=Sakaguchi en-aut-mei=Masakiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SogawaChiharu en-aut-sei=Sogawa en-aut-mei=Chiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SogawaNorio en-aut-sei=Sogawa en-aut-mei=Norio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 ORCID= en-aut-name=AsanumaMasato en-aut-sei=Asanuma en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Medical Neurobiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Medical Neurobiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Medical Neurobiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Medical Neurobiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Medical Neurobiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Medical Neurobiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Cell Biology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Food and Health Sciences, Faculty of Environmental Studies, Hiroshima Institute of Technology kn-affil= affil-num=9 en-affil=Department of Medical Neurobiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Pharmacotherapy, School of Pharmacy, Shujitsu University kn-affil= affil-num=11 en-affil=Department of Medical Neurobiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Rotenone kn-keyword=Rotenone en-keyword=Astrocyte kn-keyword=Astrocyte en-keyword=Microglia kn-keyword=Microglia en-keyword=SPARC kn-keyword=SPARC en-keyword=Parkinson's disease kn-keyword=Parkinson's disease 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=20251102 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=PGN_0298 in the Assembly and Insertion Machinery (Aim) Operon Is Essential for the Viability of Porphyromonas gingivalis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Porphyromonas gingivalis is a typical periodontal pathogen, and one of its key virulence factors is the powerful protease gingipains. Gingipains are secreted via the type IX secretion system (T9SS) and are associated with the assembly and insertion machinery (Aim) operon (PGN_0296 to PGN_0301), which encodes both T9SS components and non-T9SS proteins. In this study, we investigated PGN_0298, a gene of unknown function within this operon, to elucidate its role in P. gingivalis and to gain insights into its potential function through bioinformatics analyses. Our results demonstrated that PGN_0298 is essential for the viability of P. gingivalis, despite having limited direct association with T9SS. Sequence homology and structure predictions indicate that PGN_0298 encodes a putative isoprenyl transferase. The essentiality of PGN_0298 underscores its potential as a novel drug target for the treatment of periodontal disease. en-copyright= kn-copyright= en-aut-name=OnoShintaro en-aut-sei=Ono en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakebeKatsuki en-aut-sei=Takebe en-aut-mei=Katsuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TosaIkue en-aut-sei=Tosa en-aut-mei=Ikue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishiyaYuki en-aut-sei=Nishiya en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakayamaMasaaki en-aut-sei=Nakayama en-aut-mei=Masaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=WadaTakayuki en-aut-sei=Wada en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 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=8 ORCID= affil-num=1 en-affil=Department of Oral Microbiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Dental Pharmacology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral Microbiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Oral and Maxillofacial Reconstructive Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Oral Microbiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Human Life and Ecology, Osaka Metropolitan University kn-affil= affil-num=7 en-affil=Department of Pathophysiology–Periodontal Science, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Oral Microbiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=PGN_0298 kn-keyword=PGN_0298 en-keyword=Porphyromonas gingivalis kn-keyword=Porphyromonas gingivalis en-keyword=undecaprenyl pyrophosphate synthase kn-keyword=undecaprenyl pyrophosphate synthase END start-ver=1.4 cd-journal=joma no-vol=23 cd-vols= no-issue= article-no= start-page=101081 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=AHA’s Life’s Essential-8 cardiovascular health metrics and progression of coronary artery calcification in Japanese men en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and aims: The American Heart Association’s Life’s Essential-8 (LE8) cardiovascular health (CVH) metrics is considered a comprehensive framework for optimal cardiovascular wellbeing. However, its relationship with the progression of subclinical atherosclerosis, like coronary artery calcification (CAC), is not clarified. We investigated the associations of LE8 CVH metrics with the prevalence and progression of CAC in Japanese men.
Methods: We analyzed data from 760 asymptomatic men participating in the Shiga Epidemiological Study of Subclinical Atherosclerosis. We assessed baseline (2006–2008) LE8 CVH (low, 0–49 points; moderate, 50–79 points; high, 80–100 points) using its eight components (diet, physical activity assessed by step count, smoking, sleep, body mass index, blood lipids, blood glucose, blood pressure). We quantified CAC at baseline and follow-up of 5 years employing Agatston’s method and defined its baseline prevalence (CAC >0) and progression (employing Berry’s criteria). Modified Poisson regression analyses were used to estimate risk ratio (RR) and 95 % confidence interval (CI), adjusted for age and family history of cardiovascular disease.
Results: Participants (mean [SD] age, 63.8 [9.4] years) had 63.2 % and 44.9 % prevalence of CAC at baseline and CAC progression at follow-up, respectively. Individuals with moderate and low CVH at baseline had a higher risk of prevalent CAC (RR [95 % CI], 1.42 [1.18–1.71] and 2.07 [1.67–2.57], respectively) at baseline, compared to those with high CVH. Those with moderate and low CVH at baseline had a higher risk of CAC progression (RR [95 % CI], 1.52 [1.17–1.97] and 1.99 [1.42–2.81], respectively), compared to high CVH individuals.
Conclusions: A lower LE8 CVH is significantly associated with a higher risk of prevalence and progression of CAC in general Japanese men. en-copyright= kn-copyright= en-aut-name=MondalRajib en-aut-sei=Mondal en-aut-mei=Rajib kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KadotaAya en-aut-sei=Kadota en-aut-mei=Aya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YanoYuichiro en-aut-sei=Yano en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KadowakiSayaka en-aut-sei=Kadowaki en-aut-mei=Sayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ToriiSayuki en-aut-sei=Torii en-aut-mei=Sayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KondoKeiko en-aut-sei=Kondo en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HaradaAkiko en-aut-sei=Harada en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KawashimaMegumi en-aut-sei=Kawashima en-aut-mei=Megumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MiyazawaItsuko en-aut-sei=Miyazawa en-aut-mei=Itsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SegawaHiroyoshi en-aut-sei=Segawa en-aut-mei=Hiroyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=11 ORCID= en-aut-name=WatanabeYoshiyuki en-aut-sei=Watanabe en-aut-mei=Yoshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=NakagawaYoshihisa en-aut-sei=Nakagawa en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=FujiyoshiAkira en-aut-sei=Fujiyoshi en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=MiuraKatsuyuki en-aut-sei=Miura en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil=Department of Preventive Medicine, NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= affil-num=2 en-affil=Department of Preventive Medicine, NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= affil-num=3 en-affil=Department of General Medicine, Faculty of Medicine, Juntendo University kn-affil= affil-num=4 en-affil=Department of Public Health, Shiga University of Medical Science kn-affil= affil-num=5 en-affil=Department of Preventive Medicine, NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= affil-num=6 en-affil=Department of Preventive Medicine, NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= affil-num=7 en-affil=Department of Medical Statistics, NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= affil-num=8 en-affil=Department of Preventive Medicine, NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= affil-num=9 en-affil=Department of Internal Medicine, Shiga University of Medical Science kn-affil= affil-num=10 en-affil=NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= affil-num=11 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Radiology, Shiga University of Medical Science kn-affil= affil-num=13 en-affil=Department of Cardiovascular Medicine, Shiga University of Medical Science kn-affil= affil-num=14 en-affil=Department of Hygiene, School of Medicine, Okayama Medical University kn-affil= affil-num=15 en-affil=Department of Preventive Medicine, NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= en-keyword=Life’s essential-8 kn-keyword=Life’s essential-8 en-keyword=Cardiovascular health metrics kn-keyword=Cardiovascular health metrics en-keyword=Subclinical atherosclerosis kn-keyword=Subclinical atherosclerosis en-keyword=Coronary artery calcification kn-keyword=Coronary artery calcification en-keyword=CAC progression kn-keyword=CAC progression END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=10 article-no= start-page=e0332595 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251023 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Relationship between obesity indices and cognitive function in Japanese men: A cross-sectional study en-subtitle= kn-subtitle= en-abstract= kn-abstract=We aimed to investigate the associations among various obesity indices, including visceral (VAT) and subcutaneous adipose tissue (SAT), and cognitive function in community-dwelling Japanese men. This population-based cross-sectional study used data of 853 men who participated in the follow-up examinations of the Shiga Epidemiological Study of Subclinical Atherosclerosis. Among them, we analyzed data of 776 men who completed the Cognitive Abilities Screening Instrument (CASI) and had abdominal VAT and SAT areas measured using computed tomography. The VAT-to-SAT ratio (VSR) was calculated; participants were categorized into VSR quartiles. Using analysis of covariance, we computed crude and adjusted means of the CASI total and domain scores across VSR quartiles, adjusting for potential confounders. No significant differences were observed in total CASI scores among body mass index, VAT, or SAT quartiles. However, in the multivariable-adjusted model, participants in the lowest VSR quartile (Q1) had significantly lower CASI total scores than those in the third quartile (Q3) (Q1: 89.5, Q3: 90.9). Low VSR was independently associated with lower cognitive function in a community-based sample of middle-aged and older Japanese men. In summary, VSR may be associated with cognitive function in Japanese men, highlighting the importance of fat distribution in cognitive health and highlighting VSR as a useful indicator. en-copyright= kn-copyright= en-aut-name=MatsunoSatoshi en-aut-sei=Matsuno en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OzekiYuji en-aut-sei=Ozeki en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KadowakiSayaka en-aut-sei=Kadowaki en-aut-mei=Sayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ToriiSayuki en-aut-sei=Torii en-aut-mei=Sayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KondoKeiko en-aut-sei=Kondo en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyagawaNaoko en-aut-sei=Miyagawa en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ShimaAzusa en-aut-sei=Shima en-aut-mei=Azusa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OhashiMizuki en-aut-sei=Ohashi en-aut-mei=Mizuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MiyazawaItsuko en-aut-sei=Miyazawa en-aut-mei=Itsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SegawaHiroyoshi en-aut-sei=Segawa en-aut-mei=Hiroyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=11 ORCID= en-aut-name=KadotaAya en-aut-sei=Kadota en-aut-mei=Aya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MiuraKatsuyuki en-aut-sei=Miura en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Psychiatry, Shiga University of Medical Science kn-affil= affil-num=2 en-affil=Department of Psychiatry, Shiga University of Medical Science kn-affil= affil-num=3 en-affil=NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= affil-num=4 en-affil=NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= affil-num=5 en-affil=NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= affil-num=6 en-affil=Department of Preventive Medicine and Public Health, Keio University School of Medicine kn-affil= affil-num=7 en-affil=Department of Clinical Nursing, Shiga University of Medical Science kn-affil= affil-num=8 en-affil=NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= affil-num=9 en-affil=Department of Medicine, Shiga University of Medical Science kn-affil= affil-num=10 en-affil=NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= affil-num=11 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= affil-num=13 en-affil=NCD Epidemiology Research Center, Shiga University of Medical Science kn-affil= END
