This amendment allowed all companies and individuals to freely conduct such transactions.
 This paper first examines the basis for the tax authorities' view that "gains or losses from foreign currency transfers constitute miscellaneous income," drawing from government witness testimony in the Diet and the Tokyo District Court judgement of March 9, 2023. Then it concludes that the 1998 legal amendment, by enabling anyone to freely conduct foreign currency transactions both internationally and domestically, transformed foreign currency into a means of payment functioning as a measure of value. Consequently, it became impossible to conceptualize foreign currency as an asset subject to appreciation or depreciation, leading to the reclassification of income from its transfer from capital gains to miscellaneous income. kn-abstract= 1998年の外国為替及び外国貿易管理法の改正(以降,外国為替及び外国貿易法に改名)により,それまで外国為替公認銀行に原則として限られていた外国為替取引が,あらゆる企業及び個人に解放され,自由に行うことができるようになった。
 本稿は,まず課税当局の「外国通貨の譲渡による損益は雑所得に該当する」との見解の判断根拠を,国会における政府参考人答弁及び東京地裁令和5年3月9日判決から読み解き,そのうえで,1998年の法改正により外国通貨取引が対外及び国内において何人も自由に行うことができるようになったことから,外国通貨は支払手段として言わば価値の尺度として機能するようになり,資産の値上がり,値下がりを観念することができなくなった結果として,その譲渡による所得区分が譲渡所得から雑所得へと変化したとの結論を導くものである。 en-copyright= kn-copyright= en-aut-name=NakagawaYoshiyuki en-aut-sei=Nakagawa en-aut-mei=Yoshiyuki kn-aut-name=中川吉之 kn-aut-sei=中川 kn-aut-mei=吉之 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=6 article-no= start-page=oeaf162 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=Sex differences in the progression of cardiovascular–kidney–metabolic syndrome en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aims Cardiovascular–kidney–metabolic (CKM) syndrome is a novel disease concept; however, sex differences in its progression remain uncertain. This study aimed to quantify the risk of cardiovascular disease (CVD) events across CKM stages and to explore sex differences in this association.
Methods and results We included 1 332 436 individuals (581 423 males and 751 013 females) from the DeSC database between 2014 and 2023 who had no prior CVD (i.e. CKM Stage 4). CKM stages were categorized as follows: Stage 0 (no CKM risk factors); Stage 1 (excess or dysfunctional adiposity); Stage 2 [metabolic risk factors and chronic kidney diseases (CKD)], and Stage 3 (subclinical CVD). We used Cox models to examine the association of CKM stages with the risk of CVD events (newly developed CKM Stage 4), including myocardial infarction, stroke, heart failure, atrial fibrillation, and peripheral artery disease. The progression from CKM Stages 0 to 3 showed a dose-dependent increase in adjusted hazard ratios (HR) for developing CVD events, with the highest risk at Stage 3 [1.85 (95% CI: 1.80–1.90)]. A similar pattern was observed in both males and females. However, the magnitude of associations for CKM stages 1–3 differed between the sexes: HR by Stage 1, 1.12 (1.04–1.21) vs. 1.12 (1.07–1.16); by Stage 2, 1.78 (1.69–1.88) vs. 1.43 (1.39–1.48); by Stage 3, 1.99 (1.89–2.10) vs. 1.82 (1.76–1.88); and P-for-interaction values were 0.87, < 0.001, and 0.005, respectively.
Conclusion In this large nationwide cohort, CKM stage progression was associated with higher CVD risk in both sexes, with modest sex-specific differences. These findings highlight the value of CKM staging for early risk assessment, regardless of sex. en-copyright= kn-copyright= en-aut-name=TayaSatoshi en-aut-sei=Taya en-aut-mei=Satoshi kn-aut-name=

value of right atrial strain in patients with chronic heart failure en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aims Right ventricular dysfunction is a well-established prognostic marker in patients with heart failure (HF). However, the prognostic significance of right atrial (RA) function remains unclear. Given its sensitivity to systemic congestion, RA function may provide additional insights into HF disease progression and management. This study aimed to investigate whether RA reservoir function serves as an independent prognostic indicator in patients with chronic HF.
Methods A total of 613 patients with chronic HF and a left ventricular (LV) ejection fraction of less than 50% who underwent echocardiographic assessment at Okayama University Hospital between January 2018 and March 2023 were included (median age: 68 (58–76) years; 69% male). RA reservoir function was quantified using two-dimensional speckle-tracking echocardiography. The primary endpoint was cardiovascular death or HF-related hospitalization. Kaplan–Meier survival analysis was performed to examine the association between RA reservoir function and clinical outcomes.
Results During a median follow-up period of 41 months (range: 12–91 months), 119 patients experienced cardiac events. Compared with event-free patients, those with cardiac events exhibited a significantly larger RA maximum volume index (38 mL/m2 vs. 31 mL/m2, P < 0.001) and a significantly lower RA reservoir longitudinal strain (RASr) (17% vs. 22%, P < 0.001). Kaplan–Meier analysis demonstrated that patients with RASr ≤ 20% had significantly poorer event-free survival than those with RASr > 20%, even without RA volume enlargement (log-rank test, P < 0.001). Multivariate Cox regression analysis identified RASr as an independent predictor of cardiac events (hazard ratio: 0.95, 95% confidence interval: 0.93 to 0.97, P < 0.001).
Conclusions In patients who experienced adverse cardiac events, a reduced RASr and an increased RA maximum volume were observed. Furthermore, a reduced RASr was independently associated with an increased risk of cardiovascular death and HF-related hospitalization in patients with chronic HF and LV dysfunction. These findings indicate that RASr may serve as a valuable prognostic marker for the risk stratification and management of chronic HF. en-copyright= kn-copyright= en-aut-name=NakayamaRie en-aut-sei=Nakayama en-aut-mei=Rie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakayaYoichi en-aut-sei=Takaya en-aut-mei=Yoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakashimaMitsutaka en-aut-sei=Nakashima en-aut-mei=Mitsutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishiharaTakahiro en-aut-sei=Nishihara en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TohNorihisa en-aut-sei=Toh en-aut-mei=Norihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ToruMiyoshi en-aut-sei=Toru en-aut-mei=Miyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakamuraKazufumi en-aut-sei=Nakamura en-aut-mei=Kazufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YuasaShinsuke en-aut-sei=Yuasa en-aut-mei=Shinsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Science, Okayama University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Science, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Science, Okayama University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Science, Okayama University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Science, Okayama University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Science, Okayama University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Science, Okayama University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of Cardiovascular Medicine, Dentistry and Pharmaceutical Science, Okayama University Graduate School of Medicine kn-affil= en-keyword=Right atrial function kn-keyword=Right atrial function en-keyword=Right atrial strain kn-keyword=Right atrial strain en-keyword=Chronic heart failure kn-keyword=Chronic heart failure en-keyword=Echocardiography kn-keyword=Echocardiography END start-ver=1.4 cd-journal=joma no-vol=7 cd-vols= no-issue=2 article-no= start-page=e70170 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=Safety and efficacy of Rezūm water vapour energy therapy in BPH patients receiving antithrombotic therapy: A Japanese single‐centre experience en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: The objective of this study is to evaluate the safety and efficacy of Rezūm water vapour energy therapy (WAVE) in Japanese patients with benign prostatic hyperplasia (BPH) continuing antithrombotic therapy and to validate the Okayama University Modified Clavien-Dindo classification (OU-mCD) for perioperative hematuria.
Patients and Methods: We retrospectively analysed 80 consecutive patients who underwent WAVE from August 2023 to July 2024, including 37 (46.2%) continuing antithrombotic therapy perioperatively. Hematuria within 30 days was graded using conventional Clavien-Dindo classification and the OU-mCD, a novel classification focusing on intervention necessity. We assessed clinically significant hematuria (Grade ≥ Ib), catheter-free rate, prostate volume reduction and haemoglobin change.
Results: Clinically significant hematuria occurred in 21.6% (8/37) of patients continuing antithrombotic therapy versus 4.7% (2/43) without (p = 0.038). All 10 Grade ≥ Ib cases occurred during hospitalization with the catheter in place and were managed conservatively with continuous bladder irrigation (median 1 day); none required transfusion or surgical reintervention. Only one patient required temporary drug discontinuation. Treatment efficacy did not differ by antithrombotic status: 86.2% achieved PVR < 50 ml with 44% mean prostate volume reduction. Multivariate analysis identified antithrombotic therapy as the sole independent risk factor for Grade ≥ Ib hematuria (OR 5.46, 95% CI 1.06–28.16, p = 0.042).
Conclusion: WAVE can be safely performed with continued antithrombotic therapy. Whereas Grade ≥Ib hematuria occurred in 25% of antiplatelet/anticoagulant users (vs. 5% without), 75% had no significant bleeding, and all complications were managed conservatively without transfusion. The OU-mCD provides precise complication stratification. These findings suggest outpatient procedures may be feasible with appropriate patient selection. en-copyright= kn-copyright= en-aut-name=MoriwakeTakatoshi en-aut-sei=Moriwake en-aut-mei=Takatoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TominagaYusuke en-aut-sei=Tominaga en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KatayamaSatoshi en-aut-sei=Katayama en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KakuHaruki en-aut-sei=Kaku en-aut-mei=Haruki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TsuboiIchiro en-aut-sei=Tsuboi en-aut-mei=Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshinagaKasumi en-aut-sei=Yoshinaga en-aut-mei=Kasumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YamanoiTomoaki en-aut-sei=Yamanoi en-aut-mei=Tomoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KawadaTatsushi en-aut-sei=Kawada en-aut-mei=Tatsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SadahiraTakuya en-aut-sei=Sadahira en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=IwataTakehiro en-aut-sei=Iwata en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NishimuraShingo en-aut-sei=Nishimura en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=BekkuKensuke en-aut-sei=Bekku en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=KatayamaYasuhiro en-aut-sei=Katayama en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 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=14 ORCID= affil-num=1 en-affil=Department of Urology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Urology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Urology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Urology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Urology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Urology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Urology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Urology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Urology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Urology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=11 en-affil=Department of Urology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=12 en-affil=Department of Urology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=13 en-affil=Department of Urology, Okamura Isshindo Hospital kn-affil= affil-num=14 en-affil=Department of Urology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=benign prostatic hyperplasia kn-keyword=benign prostatic hyperplasia en-keyword=hematuriaantithrombotic therapy kn-keyword=hematuriaantithrombotic therapy en-keyword=Japanese kn-keyword=Japanese en-keyword=OU-mCD kn-keyword=OU-mCD en-keyword=water vapour energy therapy kn-keyword=water vapour energy therapy END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=11 article-no= start-page=e2543107 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251112 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Trastuzumab Deruxtecan for ERBB2-Mutant Metastatic Non–Small Cell Lung Cancer With or Without Brain Metastases: A Secondary Analysis of Randomized Clinical Trials en-subtitle= kn-subtitle= en-abstract= kn-abstract=Importance Brain metastases reduce overall survival rates of patients with non–small cell lung cancer (NSCLC); patients with epidermal growth factor receptor 2 (ERBB2 [formerly HER2])–mutant NSCLC are more likely to have baseline brain metastases. Trastuzumab deruxtecan (T-DXd) is an approved ERBB2-directed treatment for previously treated unresectable or metastatic ERBB2-mutant NSCLC.
Objective To assess the clinical effectiveness and safety of T-DXd 5.4 mg/kg and 6.4 mg/kg doses in patients with previously treated ERBB2-mutant metastatic NSCLC with or without untreated or previously treated stable brain metastases.
Design, Setting, and Participants This post hoc secondary analysis pooled patients from the DESTINY-Lung01 (data cutoff date: December 3, 2021) and DESTINY-Lung02 (data cutoff date: December 23, 2022) clinical trials by T-DXd dose (5.4 mg/kg and 6.4 mg/kg). DESTINY-Lung01 was a multicenter, open-label, 2-cohort, nonrandomized phase 2 study, while DESTINY-Lung02 was a dose-blinded, multicenter, 2-cohort, randomized phase 2 study. Participants had a previously treated ERBB2-mutant metastatic NSCLC with or without untreated or previously treated stable brain metastases at baseline. All statistical analyses were performed from April 2023 to October 2024.
Intervention Patients received a T-DXd dose of either 5.4 mg/kg or 6.4 mg/kg intravenously every 3 weeks.
Main Outcome and Measure Systemic and intracranial effectiveness by blinded independent central review using RECIST (Response Evaluation Criteria in Solid Tumors) version 1.1, sites of progression, and safety.
Results This analysis included 102 patients in the T-DXd 5.4-mg/kg dose group (65 females [64%]; median [range] age, 57.5 [37.0-83.0] years and 59.5 [30.0-79.0] years in patients with and without brain metastases, respectively) and 141 patients in the T-DXd 6.4-mg/kg dose group (94 females [67%]; median [range] age, 62.5 [29.0-88.0] years and 59.0 [27.0-83.0] years in patients with and without brain metastases, respectively). In each group, 31% (32 of 102) and 38% (54 of 141) of patients, respectively, had baseline brain metastases and 53% (17 of 32) and 44% (24 of 54), respectively, received prior brain metastasis treatment. In patients with and without brain metastases, systemic confirmed objective response rates (ORRs) were 47% (15 of 32; 95% CI, 29%-65%) and 50% (35 of 70; 95% CI, 38%-62%), respectively, with the T-DXd 5.4-mg/kg dose, and 50% (27 of 54; 95% CI, 36%-64%) and 59% (51 of 87; 95% CI, 48%-69%) with the T-DXd 6.4-mg/kg dose. Median progression-free survival was 7.1 (95% CI, 5.5-9.7) months in the T-DXd 5.4-mg/kg dose group and 7.1 (95% CI, 4.5-9.6) months in the T-DXd 6.4-mg/kg dose group of patients with baseline brain metastases. Among patients with measurable baseline brain metastases, intracranial confirmed ORRs were 50% (7 of 14; 95% CI, 23%-77%) with the T-DXd 5.4-mg/kg dose and 30% (9 of 30; 95% CI, 15%-49%) with the T-DXd 6.4-mg/kg dose. At both doses, the safety profile of T-DXd was generally manageable, regardless of baseline brain metastases, favoring the T-DXd 5.4 mg/kg dose.
Conclusions and Relevance In this secondary analysis, T-DXd at the approved dose of 5.4 mg/kg showed antitumor activity in patients with previously treated ERBB2-mutant metastatic NSCLC with or without brain metastases. This finding supports T-DXd 5.4 mg/kg use in this population. en-copyright= kn-copyright= en-aut-name=JännePasi A. en-aut-sei=Jänne en-aut-mei=Pasi A. kn-aut-name= kn-aut-sei= kn-aut-mei=

Patient-Reported Outcomes From DESTINY-Lung02—A Dose-Blinded, Randomized, Phase 2 Study of Trastuzumab Deruxtecan in Patients With HER2-Mutant Metastatic NSCLC en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Trastuzumab deruxtecan (T-DXd) demonstrated strong and durable responses in patients with previously treated HER2 (ERBB2) mutant (HER2m) metastatic NSCLC (mNSCLC) in the DESTINY-Lung02 primary analysis (December 23, 2022, data cutoff). This final analysis evaluated T-DXd efficacy and safety after 8 additional months of follow-up, including clinically relevant subgroups and patient-reported outcomes.
Methods: DESTINY-Lung02 was a randomized, dose-blinded, multicenter, phase 2 trial. Patients with previously treated HER2m mNSCLC were randomized 2:1 to receive T-DXd 5.4 or 6.4 mg/kg once every 3 weeks. Primary end point was confirmed objective response rate by blinded independent central review.
Results: As of August 25, 2023, 102 and 50 patients had received T-DXd 5.4 or 6.4 mg/kg, respectively. Median follow-up (Q1–Q3) was 15.8 (8.2–20.7) months and 16.5 (9.4–20.8) months, respectively. Confirmed objective response rate (95% confidence interval) was 50.0% (51/102; 39.9%–60.1%) and 56.0% (28/50; 41.3%–70.0%), respectively. Safety profile was acceptable and generally manageable. Accordingly, median treatment duration (Q1–Q3) was 7.7 (3.7–14.4) months and 8.3 (2.8–13.1) months; drug-related grade 3 or higher treatment-emergent adverse events occurred in 39.6% (40/101) and 60.0% (30/50), with nausea most common (67.3% [68/101], 82.0% [41/50]). Adjudicated drug-related interstitial lung disease occurred in 14.9% (15/101) and 32.0% (16/50), mostly grade 1 or 2 with one grade 5 in each arm. Health-related quality of life was preserved for the duration of T-DXd treatment while sample size was sufficient for analysis, with no adverse effects on health-related quality of life observed at either dose.
Conclusions: T-DXd demonstrated strong and durable responses at both doses, with no clinically significant changes in toxicity. The approved 5.4-mg/kg dose demonstrated a more favorable benefit-risk profile, including lower adjudicated drug-related interstitial lung disease incidence.

学年)を対象に,理科的内容を扱う教科の気候変動に関する内容の取り扱いの現状を分析した。分析では UNESCO による SDGs のための教育と Kagawa & Selby の「理解・緩和・適応」の考え方をもとに観点を設け,記述を抽出・分類した。その結果,初等教育段階の「The World Around Us」では生活世界に根ざした環境配慮の態度と行動の基礎形成が重視され,前期中等教育段階の「Science」では科学的な因果関係や気候変動対策の国際的枠組みが導入されており段階的深化が確認された。一方で,概念導入の遅れ,因果連鎖の不統一,行動変容に至る仕組みの弱さ,学際性の不足や語彙や概念の習得のスパイラルな学習の不足が明らかになった。現行教科書は,体系的かつ実効的な気候変動教育には未だ不十分であり,今後の改善が求められることを指摘した。

intervention on pre-frailty or frailty in older people: a randomized clinical trial en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Frailty is often experienced by older adults, which can lead to long-term health problems. We aimed to examine associations with improvements in nutritional status, sarcopenia (age-related loss of skeletal muscle mass and strength), and frailty in four groups with different oral exercise frequencies.
Methods: We conducted a prospective, parallel multi-arm randomized controlled trial (Japan Registry of Clinical Trials (jRCT) 1062210063) to test the effects of oral exercise on frailty in older adults. Each intervention consisted of a standardized oral exercise protocol including neck exercises, lip exercises, and tongue movements, designed to improve oral function and reduce frailty. The primary outcome was the change in the number of frailty criteria from baseline to follow-up. Individuals aged ≥60 years were screened for frailty status using standardized criteria at the Department of Preventive Dentistry at Okayama University Hospital between October 2022 and December 2023. Those identified as pre-frailty or frailty were eligible and enrolled in the study. After screening 60 individuals, 58 eligible participants were randomly assigned using block randomization to one of four oral exercise frequency groups: 3 times/day & everyday, 3 times/day & 3 days/week, once/day & everyday, and once/day & 3 days/week. A two-way repeated measures analysis of variance was used to evaluate the impact of the four frequencies of oral exercise methods on frailty in older adults. Outcome assessors were blinded; participants were not.
Results: Here we show the results of the 58 participants. Group sizes are: 3 times/day & everyday (n = 14), 3 times/day & 3 days/week (n = 15), once/day & everyday (n = 14), once/day & 3 days/week (n = 15). The trial is completed as planned, and all randomized participants are analyzed. The main effect of time is significant for the number of frailty criteria (F = 14.803, p < 0.001, partial eta squared = 0.215). The mean changes from baseline to follow-up are −0.357 (95% Confidence Interval −0.787 to 0.073) in the 3 times/day & everyday group, −0.600 (95% Confidence Interval −1.255 to 0.055) in the 3 times/day & 3 days/week group, −0.571 (95% Confidence Interval −1.379 to 0.236) in the once/day & everyday group, and −0.600 (95% Confidence Interval −1.008 to −0.192) in the once/day & 3 days/week group. The main effect of time is also significant for the number of oral hypofunction criteria (F = 16.456, p < 0.001, partial eta squared = 0.234). No important adverse events or side effects related to the intervention were observed.
Conclusions: After conducting oral exercises for 3 months on older adults with pre-frailty or frailty, improvements in frailty are observed. Overall, these exercises could be a simple, low-cost way to support healthy aging in the community. en-copyright= kn-copyright= en-aut-name=TakeuchiNoriko en-aut-sei=Takeuchi en-aut-mei=Noriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SawadaNanami en-aut-sei=Sawada en-aut-mei=Nanami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=InadaSakura en-aut-sei=Inada en-aut-mei=Sakura kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoritaManabu en-aut-sei=Morita en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=EkuniDaisuke en-aut-sei=Ekuni en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Preventive Dentistry, Division of Dentistry, Medical Development Field, Okayama University kn-affil= affil-num=2 en-affil=Section of Preventive and Public Health Dentistry, Division of Oral Health, Growth and Development, Faculty of Dental Science, Kyushu University kn-affil= affil-num=3 en-affil=Division of Health Promotion, Okayama-City Health Center kn-affil= affil-num=4 en-affil=Department of Oral Health Sciences, Faculty of Health Care Sciences, Takarazuka University of Medical and Health Care kn-affil= affil-num=5 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=164 cd-vols= no-issue= article-no= start-page=108315 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Global trends in Clostridioides difficile infection–related mortality, 2001-2023: An observational study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: Clostridioides difficile infection (CDI) is a major public health concern, particularly in aging populations. The aim of this study was to evaluate global trends in CDI-related mortality to inform sustainable and cost-effective management strategies.
Methods: We conducted an observational study using mortality data from the World Health Organization (WHO) database spanning 2001 to 2023. Sixty-three countries with satisfactory data quality and at least 12 years of data between 2001 and 2023 were included. Crude and age-standardized CDI-related mortality rates per 1,000,000 individuals were calculated after stratification by age, sex, WHO region, and sociodemographic index (SDI). Global trends were analyzed using locally weighted regression.
Results: The global age-standardized CDI-related mortality rate was 0.76 per 1,000,000 individuals in 2001, peaked at 4.08 in 2010, and declined to 2.44 in 2023. The most notable downward trends were observed in the Americas and high-SDI countries. These improvements may reflect the impact of multidisciplinary efforts in CDI prevention and management.
Conclusions: Although CDI-related mortality has declined globally over the past decade, the disease remains a significant threat, especially in older populations. Ongoing global efforts are essential to further reduce CDI-related deaths. en-copyright= kn-copyright= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishimuraYoshito en-aut-sei=Nishimura en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HaradaKo en-aut-sei=Harada en-aut-mei=Ko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamamotoMaki en-aut-sei=Yamamoto en-aut-mei=Maki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakedaTatsuaki en-aut-sei=Takeda en-aut-mei=Tatsuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=VuQuynh Thi en-aut-sei=Vu en-aut-mei=Quynh Thi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=BelangoyKeith Pardillada en-aut-sei=Belangoy en-aut-mei=Keith Pardillada kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OuddoudHanane en-aut-sei=Ouddoud en-aut-mei=Hanane kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ZamamiYoshito en-aut-sei=Zamami en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KoyamaToshihiro en-aut-sei=Koyama en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=2 en-affil=Division of Hematology/Oncology, Mayo Clinic kn-affil= affil-num=3 en-affil=Brookdale Department of Geriatrics and Palliative Medicine, Icahn School of Medicine at Mount Sinai kn-affil= affil-num=4 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil= kn-affil= affil-num=6 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Health Data Science, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Aging kn-keyword=Aging en-keyword=Locally weighted regression model kn-keyword=Locally weighted regression model en-keyword=Infection kn-keyword=Infection en-keyword=Clostridioides difficile kn-keyword=Clostridioides difficile en-keyword=Disparity kn-keyword=Disparity END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=1 article-no= start-page=69 end-page=74 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=Effective Treatment of Advanced Hepatocellular Carcinoma with Extensive Peritoneal Dissemination Using Lenvatinib en-subtitle= kn-subtitle= en-abstract= kn-abstract=Patients with hepatocellular carcinoma (HCC) and extensive peritoneal dissemination generally have a poor prognosis and are often resistant to systemic therapy. We report the case of a 47-year-old woman with HCC and massive peritoneal dissemination who presented with malignant ascites requiring repeated cell-free and concentrated ascites reinfusion therapy and peritoneovenous shunt placement, as well as malignant pleural effusion requiring pleurodesis. Combined immunotherapy with durvalumab/tremelimumab was initiated;however, disease progression was observed after three treatment courses, prompting a switch to lenvatinib therapy. Two months after initiation of lenvatinib, CT imaging demonstrated complete disappearance of arterial enhancement in the primary hepatic lesion, along with reduction in the size of peritoneal dissemination nodules. Thirteen months after switching to lenvatinib (16 months after the initial diagnosis), the alpha-fetoprotein level continued to decrease, and the disease remained stable under treatment. Despite the extremely high tumor burden, lenvatinib achieved disease stabilization and symptomatic improvement. en-copyright= kn-copyright= en-aut-name=WakatsukiShinya en-aut-sei=Wakatsuki en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakamotoShinya en-aut-sei=Sakamoto en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UenoAkiko en-aut-sei=Ueno en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NambaTakaomi en-aut-sei=Namba en-aut-mei=Takaomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamamotoYorito en-aut-sei=Yamamoto en-aut-mei=Yorito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MatsumotoManabu en-aut-sei=Matsumoto en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IwataJun en-aut-sei=Iwata en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OkabayashiTakehiro en-aut-sei=Okabayashi en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Obstetrics and Gynecology, Kochi Health Sciences Center kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Kochi Health Sciences Center kn-affil= affil-num=3 en-affil=Department of Obstetrics and Gynecology, Kochi Health Sciences Center kn-affil= affil-num=4 en-affil=Department of Obstetrics and Gynecology, Kochi Health Sciences Center kn-affil= affil-num=5 en-affil=Department of Obstetrics and Gynecology, Kochi Health Sciences Center kn-affil= affil-num=6 en-affil=Department of Diagnostic Pathology, Kochi Health Sciences Center kn-affil= affil-num=7 en-affil=Department of Diagnostic Pathology, Kochi Health Sciences Center kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Kochi Health Sciences Center kn-affil= en-keyword=diagnostic laparoscopy kn-keyword=diagnostic laparoscopy en-keyword=hepatocellular carcinoma kn-keyword=hepatocellular carcinoma en-keyword=peritoneal dissemination kn-keyword=peritoneal dissemination en-keyword=lenvatinib kn-keyword=lenvatinib END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=1 article-no= start-page=55 end-page=62 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=Changes in Prescribing Patterns of Antiviral Drugs before and after Public Coverage Termination among Hospitalized COVID-19 Patients in Regional Hospitals in Japan: A Retrospective, Multicenter Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=In Japan, antiviral agents for COVID-19 were freely available until September 2023 as part of national policy. This study evaluated changes in these agents’ prescribing patterns and the patient outcomes following the policy shift. We conducted a multicenter retrospective study at four hospitals in Japan’s Okayama and Kagawa prefectures from January 2022 to March 2024. The study period was divided into the public-expenditure phase (January 2022 to September 2023) and the post-expenditure phase (October 2023 to March 2024). We extracted the hospitalized patients’ clinical data from the electronic database. The study’s primary outcome was the antiviral prescription rate; the secondary outcome was in-hospital mortality. Among the 302 hospitalized patients (median age 85 years), 52.0% were classified as having a mild condition. Of the patients with mild conditions, 37.7% were diagnosed in outpatient settings prior to hospitalization. During the public-expenditure phase, 47.4% of the patients received antivirals as outpatients, mainly molnupiravir (80.9%). In the post-expenditure period, 80.0% of the patients were prescribed antivirals, mostly molnupiravir (91.7%). The antiviral prescription rate was significantly higher after the policy change. The overall in-hospital mortality was 15.8%, with no significant difference between the two periods (17.0% vs. 10.5%). Despite the termination of government funding, antiviral prescriptions remained frequent at community hospitals located in highly aging regions of western Japan such as Okayama and Kagawa prefectures. Mortality remains high among the elderly, highlighting the need for continued antiviral therapy and booster vaccinations. en-copyright= kn-copyright= en-aut-name=AkazawaHidemasa en-aut-sei=Akazawa en-aut-mei=Hidemasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FukushimaShinnosuke en-aut-sei=Fukushima en-aut-mei=Shinnosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamamotoShohei en-aut-sei=Yamamoto en-aut-mei=Shohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakanoYasuhiro en-aut-sei=Nakano en-aut-mei=Yasuhiro 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= affil-num=1 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, kn-affil= affil-num=2 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, kn-affil= affil-num=5 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, kn-affil= affil-num=6 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, kn-affil= en-keyword=coronavirus disease 2019 kn-keyword=coronavirus disease 2019 en-keyword=public expenditure kn-keyword=public expenditure en-keyword=prescribing pattern kn-keyword=prescribing pattern en-keyword=prognosis kn-keyword=prognosis en-keyword=Japan kn-keyword=Japan END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=1 article-no= start-page=47 end-page=54 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=Time Course of the Development and Loss of Delta-9-tetrahydrocannabinol Tolerance: Effects on Hypothermia and Spontaneous Locomotor Activity in Mice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Deregulation of cannabis use is gradually expanding in Europe and the United States. However, the biological processes driving tolerance to delta-9-tetrahydrocannabinol (Δ9-THC), the main psychoactive component of cannabis, remain unclear. Thus, this study aimed to investigate the mechanisms and time course of tolerance development and loss to Δ9-THC in mice. Male ICR mice (7 weeks old) were administered Δ9-THC once daily for 3 days and then divided into three groups according to the washout period (3-, 10-, and 17-day washout groups). After each washout, changes in body temperature and locomotor activity were measured following re-exposure to Δ9-THC. Furthermore, the mRNA expression levels of CB1 and CB2 receptors in the brain were evaluated using real-time PCR. On day 1, significant hypothermia and reduced spontaneous locomotor activity were observed in the Δ9-THC-treated mice compared with the vehicle-treated mice. Tolerance to the hypothermic and locomotor-suppressing effects of Δ9-THC developed on days 2 and 3, respectively, and dissipated after 3 and 11 days of washout, respectively. These differences in the rates of tolerance development and recovery may reflect distinct underlying mechanisms. No significant changes in receptor mRNA expression were observed. These findings highlight the complexity of Δ9-THC tolerance and its potential implications for long-term cannabis use. en-copyright= kn-copyright= en-aut-name=EguchiYukiomi en-aut-sei=Eguchi en-aut-mei=Yukiomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UshioSoichiro en-aut-sei=Ushio en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IrieKeiichi en-aut-sei=Irie en-aut-mei=Keiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamashitaYuta en-aut-sei=Yamashita en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=EguchiMiyu en-aut-sei=Eguchi en-aut-mei=Miyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakanoTakafumi en-aut-sei=Nakano en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MishimaKenichi en-aut-sei=Mishima 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 Physiology and Pharmacology, Faculty of Pharmaceutical Sciences, Fukuoka University kn-affil= affil-num=2 en-affil=Department of Emergency and Disaster Medical Pharmacy, Faculty of Pharmaceutical Sciences, Fukuoka University kn-affil= affil-num=3 en-affil=Department of Physiology and Pharmacology, Faculty of Pharmaceutical Sciences, Fukuoka University kn-affil= affil-num=4 en-affil=Department of Physiology and Pharmacology, Faculty of Pharmaceutical Sciences, Fukuoka University kn-affil= affil-num=5 en-affil=Department of Emergency and Disaster Medical Pharmacy, Faculty of Pharmaceutical Sciences, Fukuoka University kn-affil= affil-num=6 en-affil=Department of Oncology and Infectious Disease Pharmacy, Faculty of Pharmaceutical Sciences, Fukuoka University kn-affil= affil-num=7 en-affil=Department of Physiology and Pharmacology, Faculty of Pharmaceutical Sciences, Fukuoka University kn-affil= en-keyword=delta-9-tetrahydrocannabinol kn-keyword=delta-9-tetrahydrocannabinol en-keyword=cannabis kn-keyword=cannabis en-keyword=tolerance kn-keyword=tolerance en-keyword=locomotor kn-keyword=locomotor en-keyword=hypothermic kn-keyword=hypothermic END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=1 article-no= start-page=31 end-page=37 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=The Preoperative Anterior Pelvic Plane Angle Predicts Cup Anteversion Changes at 1 Year after Total Hip Arthroplasty en-subtitle= kn-subtitle= en-abstract= kn-abstract=We investigated global alignment changes following total hip arthroplasty (THA) and predictive alignment parameters for increased cup anteversion (CA) by retrospectively analyzing the primary THA data of 75 patients treated at our hospital (49 women, 26 men; age 65.1±5.7 years, BMI 28.3±3.4 kg/m2). Global alignment parameters, i.e., the anterior pelvic plane angle (APPa) and proximal femoral shaft angle (PFSa) and other alignment parameters were measured. CA was evaluated based on the patients’ standing coronal radiographs. ΔCA was defined as the difference in CA from 2 weeks before to 1 year after each THA. We classified the cases as stable (S) (CA < 10°; n=63) and pelvic retroversion (R) (CA ≥ 10°; n=12) groups. Associations between ΔCA and alignment parameters were evaluated by linear regression and a receiver operating characteristic (ROC) analysis. A significant decrease in the PFSa occurred between the 2-week and 1-year post-THA timepoints (7.8±4.3° vs. 4.2±3.6°, p<0.001), with no notable change in other alignment parameters. At 1-year post-THA, the CA of 12 (16%) patients had increased to 4.5±4.4°. Only the preoperative APPa was positively associated with ΔCA (β=0.165, p=0.020). The ROC analysis revealed that the optimal cut-off value for increased CA in the APPa is 2.1° (area under the curve, 0.700; p=0.020; odds ratio, 4.80). The APPa change predicted increased CA, which emphasizes the importance of the use of preoperative standing radiography for identifying the optimal cup positioning for post-THA changes in CA. en-copyright= kn-copyright= en-aut-name=IshibashiKyota en-aut-sei=Ishibashi en-aut-mei=Kyota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OishiHirotaka en-aut-sei=Oishi en-aut-mei=Hirotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ArakiRyo en-aut-sei=Araki en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KawamuraKosuke en-aut-sei=Kawamura en-aut-mei=Kosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SasakiIsamu en-aut-sei=Sasaki en-aut-mei=Isamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SasakiEiji en-aut-sei=Sasaki en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KamadaHikaru en-aut-sei=Kamada en-aut-mei=Hikaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KogawaMasakazu en-aut-sei=Kogawa en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TanakaSunao en-aut-sei=Tanaka en-aut-mei=Sunao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NumasawaTakuya en-aut-sei=Numasawa en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=IshibashiYasuyuki en-aut-sei=Ishibashi en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Orthopedic Surgery, Hachinohe City Hospital kn-affil= affil-num=2 en-affil=Department of Orthopedic Surgery, Hachinohe City Hospital kn-affil= affil-num=3 en-affil=Department of Orthopedic Surgery, Hachinohe City Hospital kn-affil= affil-num=4 en-affil=Department of Orthopedic Surgery, Hachinohe City Hospital kn-affil= affil-num=5 en-affil=Department of Orthopedic Surgery, Hachinohe City Hospital kn-affil= affil-num=6 en-affil=Department of Orthopedic Surgery, Hirosaki University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Department of Orthopedic Surgery, Hachinohe City Hospital kn-affil= affil-num=8 en-affil=Department of Orthopedic Surgery, Hachinohe City Hospital kn-affil= affil-num=9 en-affil=Department of Orthopedic Surgery, Hachinohe City Hospital kn-affil= affil-num=10 en-affil=Department of Orthopedic Surgery, Hachinohe City Hospital kn-affil= affil-num=11 en-affil=Department of Orthopedic Surgery, Hirosaki University Graduate School of Medicine kn-affil= en-keyword=total hip arthroplasty kn-keyword=total hip arthroplasty en-keyword=global alignment kn-keyword=global alignment en-keyword=anterior pelvic plane kn-keyword=anterior pelvic plane en-keyword=cup anteversion kn-keyword=cup anteversion en-keyword=pelvic tilt kn-keyword=pelvic tilt END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=1 article-no= start-page=17 end-page=30 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=Development of a Stroke Discharge Support Evaluation Scale for Ward Nurses in Acute Care Hospitals en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study aimed to develop a scale enabling nurses to objectively evaluate their own stroke discharge support, as a basis for enhancing its overall effectiveness. A draft scale was created based on a literature review, and consisted of a 51-item, 5-point Likert-type questionnaire administered to ward nurses engaged in stroke discharge support at acute care hospitals. Factor analysis was performed to refine the scale. Construct validity was assessed using the known-groups method, and reliability was evaluated through internal consistency analysis. The resulting Stroke Discharge Support Evaluation Scale comprises 29 items across 5 factors, each rated on a 5-point Likert scale. Analysis of the data collected from 237 valid responses demonstrated good internal consistency and supported the scale’s construct validity. The Stroke Discharge Support Evaluation Scale is a reliable and valid tool enabling ward nurses in acute care hospitals to evaluate their own stroke discharge support. en-copyright= kn-copyright= en-aut-name=YanoHideki en-aut-sei=Yano en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakahataYoko en-aut-sei=Takahata en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamaguchiTakeshi en-aut-sei=Yamaguchi en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SaitoShinya en-aut-sei=Saito en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Nursing, Faculty of Human Health Sciences, Niimi University kn-affil= affil-num=2 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Nursing, Shikoku University kn-affil= affil-num=4 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= en-keyword=stroke kn-keyword=stroke en-keyword=discharge support kn-keyword=discharge support en-keyword=scale development kn-keyword=scale development END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=1 article-no= start-page=9 end-page=16 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=A Novel Nomogram that Predicts Chronic Hemodialysis Patients’ Survival Based on Their Sedentary Behavior en-subtitle= kn-subtitle= en-abstract= kn-abstract=Appropriate treatments for chronic hemodialysis patients are a public health challenge in Japan. Sedentary behavior appears to be closely associated with these patients’ survival. We thus sought to develop a nomogram that predicts survival based on the duration of chronic hemodialysis patients’ sedentary behavior. One hundred twenty-four patients under chronic hemodialysis (73 men, 51 women, age 71.7±11.1 years) were enrolled in this cohort study. The patients wore a triaxial accelerometer that measured both their sedentary behavior, i.e., total sedentary behavior (minutes) and their maximum sedentary bouts (min) on non-hemodialysis days. We obtained the Kaplan-Meier curve and used the log-rank test and a Cox proportional hazards model to evaluate the relationship between the patients’ sedentary behavior and their survival. We also used a Cox proportional hazards model to develop a nomogram for the patients’ 5-year survival rate. Forty-six patients died during the follow-up period. When we stratified the patients by the medians of total sedentary behavior and maximum sedentary bouts, we observed significant between-group differences. After adjustment for confounding factors in a Cox proportional hazards model, total sedentary behavior and maximum sedentary bouts were identified as critical survival factors, and we generated a nomogram using an index of sedentary behavior. Our analysis results demonstrated that sedentary behavior on non-dialysis days was closely associated with the survival of the chronic hemodialysis patients, suggesting that a decrease in sedentary behavior would prolong their survival. The nomogram developed herein based on sedentary behavior may be useful for predicting the outcomes of chronic hemodialysis patients. en-copyright= kn-copyright= en-aut-name=SugaharaKentaro en-aut-sei=Sugahara en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KondoTakashi en-aut-sei=Kondo en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyatakeNobuyuki en-aut-sei=Miyatake en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishiHiroyuki en-aut-sei=Nishi en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UjikeKazuhiro en-aut-sei=Ujike en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KoumotoKiichi en-aut-sei=Koumoto en-aut-mei=Kiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NamioKeiichi en-aut-sei=Namio en-aut-mei=Keiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HishiiShuhei en-aut-sei=Hishii en-aut-mei=Shuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KatayamaAkihiko en-aut-sei=Katayama en-aut-mei=Akihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SuzukiHiromi en-aut-sei=Suzuki en-aut-mei=Hiromi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YamamotoYorimasa en-aut-sei=Yamamoto en-aut-mei=Yorimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Hygiene, Faculty of Medicine, Kagawa University kn-affil= affil-num=2 en-affil=Innoshima General Hospital kn-affil= affil-num=3 en-affil=Department of Hygiene, Faculty of Medicine, Kagawa University kn-affil= affil-num=4 en-affil=Innoshima General Hospital kn-affil= affil-num=5 en-affil=Innoshima General Hospital kn-affil= affil-num=6 en-affil=Innoshima General Hospital kn-affil= affil-num=7 en-affil=Department of Hygiene, Faculty of Medicine, Kagawa University kn-affil= affil-num=8 en-affil=Department of Hygiene, Faculty of Medicine, Kagawa University kn-affil= affil-num=9 en-affil=Faculty of Social Studies, Shikokugakuin University kn-affil= affil-num=10 en-affil=Department of Hygiene, Faculty of Medicine, Kagawa University kn-affil= affil-num=11 en-affil=Innoshima General Hospital kn-affil= en-keyword=nomogram kn-keyword=nomogram en-keyword=chronic hemodialysis kn-keyword=chronic hemodialysis en-keyword=sedentary behavior kn-keyword=sedentary behavior en-keyword=Cox proportional hazards model kn-keyword=Cox proportional hazards model en-keyword=Kaplan- Meier curve kn-keyword=Kaplan- Meier curve END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=1 article-no= start-page=1 end-page=7 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=Usefulness of D-dimer Assay to Confirm the Course of Overt Venous Thromboembolism (VTE) in Cancer Patients en-subtitle= kn-subtitle= en-abstract= kn-abstract=Venous thromboembolism (VTE) is a serious complication in patients with cancer. In this population, the presence of thrombi is often assessed at cancer diagnosis by measuring D-dimer levels, which have high sensitivity but low specificity for identifying VTE at this clinical time point. However, the usefulness of D-dimer measurement during anticoagulation therapy has not been fully established, despite its widespread use. In this retrospective observational study, we investigated whether D-dimer measurement during anticoagulation therapy in cancer patients could predict overt VTE at follow-up. The study included patients who underwent D-dimer testing and contrast-enhanced computed tomography between 30 and 100 days after initiation of anticoagulation therapy. Eighty-two patients were included: 60 with cancer and 22 without. The diagnostic performance of D-dimer for overt VTE was as follows: sensitivity, 85.7%; specificity, 87.2%; positive predictive value, 78.3%; and negative predictive value, 89.2%. These findings suggest that D-dimer measurement at follow-up has high sensitivity and specificity for overt VTE in cancer patients and may aid in assessing thrombotic status. Clinically, if anticoagulation therapy is continued until D-dimer levels become negative, the absence of overt VTE could be inferred without additional invasive testing. en-copyright= kn-copyright= en-aut-name=YamaokaHidenaru en-aut-sei=Yamaoka en-aut-mei=Hidenaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshidaMasashi en-aut-sei=Yoshida en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SarashinaToshihiro en-aut-sei=Sarashina en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AkagiSatoshi en-aut-sei=Akagi en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyoshiToru en-aut-sei=Miyoshi en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MunemasaMitsuru en-aut-sei=Munemasa en-aut-mei=Mitsuru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakamuraKazufumi en-aut-sei=Nakamura en-aut-mei=Kazufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ItoHiroshi en-aut-sei=Ito en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YuasaShinsuke en-aut-sei=Yuasa en-aut-mei=Shinsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, IMS Tokyo Katsushika General Hospital kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Seisukai Kuroda Clinic kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Cardiovascular Medicine, Okayama Rosai Hospital kn-affil= affil-num=7 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of General Internal Medicine 3, Kawasaki Medical School General Medical Center kn-affil= affil-num=9 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=D-dimer kn-keyword=D-dimer en-keyword=venous kn-keyword=venous en-keyword=thromboembolism kn-keyword=thromboembolism en-keyword=cancer kn-keyword=cancer 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=2026 dt-pub=20260119 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A retrospective cohort study comparing periodontal regeneration using fibroblast growth factor‐2 versus autologous bone graft en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Fibroblast growth factor-2 (FGF-2) is a novel agent utilized in periodontal regeneration therapy. However, its clinical efficacy compared with autologous bone graft (ABG), a long-established treatment, remains unclear. This study aimed to compare the clinical outcomes of FGF-2 and ABG and to assess the impact of patient background factors on outcomes when using FGF-2.
Methods: We collected the subjects from January 2013 to September 2023. Clinical outcomes included the vertical bone defect improvement rate (VBDIR) and the probing pocket depth improvement (PPDI). Clinical outcomes between the two groups were compared using analysis of covariance (ANCOVA), adjusting for age, sex, smoking history, and hypertension. Additionally, a multilevel linear analysis was performed to assess factors influencing outcomes in FGF-2.
Results: A total of 180 sites from 141 patients (FGF-2: 150 sites; ABG: 30 sites) were evaluated. Both VBDIR and PPDI significantly improved postoperatively in both groups. There were no significant differences in clinical outcomes between FGF-2 and ABG. In FGF-2, smoking history was positively associated, while the preoperative bone defect angle (BDA) was negatively associated with clinical outcomes.
Conclusions: FGF-2 might exhibit clinical outcomes comparable to those of ABG, suggesting it is a clinically viable alternative for vertical bone defects. When using FGF-2, patient-specific factors such as smoking history and preoperative BDA should be considered carefully.

This study aimed to elucidate the relationship between antimicrobial stewardship (AS) activities and antimicrobial prescription trends and patterns.
Methods: This retrospective, multicenter, longitudinal study was conducted between April 2014 and March 2023 (9-year fiscal period). A structured, questionnaire survey, regarding institutional infrastructure and environmental parameters, service modalities provided by AS activities, resource allocation and systemic support, and data on the use of broad-spectrum antimicrobial agents, was distributed to co-investigators working at seven hospitals in Okayama, Japan. Full-time equivalent (FTE) allocation for each healthcare facility were calculated and subsequently compared among the hospitals. Temporal variations in the proportional distribution of broad-spectrum antimicrobial agents were statistically evaluated using joinpoint regression analysis.
Results: Two hospitals where pharmacists were exclusively dedicated to AS activities and met the recommended FTE allocation showed a statistically significant reduction in the proportion of broad-spectrum antibiotic administration, with average annual percentage changes of −8.0 % (95 % confidence interval [CI]: −10.5 to −5.8) and −3.1 % (95 % CI: −5.5 to −0.7), respectively. In contrast, two other hospitals with full-time AS members but insufficient FTE allocation exhibited inconsistent and statistically nonuniform trends. The remaining three healthcare institutions with poorly resourced AS teams demonstrated no statistically significant trends in their broad-spectrum antimicrobial prescriptions.
Conclusion: Our findings uncovered that hospitals with adequate FTE staffing metrics for AS activities exhibited statistically significant downward trends in the consumption of broad-spectrum antimicrobial agents. en-copyright= kn-copyright= en-aut-name=KajitaShiho en-aut-sei=Kajita en-aut-mei=Shiho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HagiyaHideharu

Retrospective Cohort Study With Propensity Score Matching Analysis (2016–2023) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background. Candidemia is a life-threatening infection with high mortality, and appropriate management is essential to improve patient outcomes. The Candida Care Bundle aims to standardize hospital management for patients with candidemia and reduce mortality.
Methods. This retrospective multicenter cohort study included candidemia cases from 9 hospitals in Japan between 2016 and 2023. Compliance to the Candida Care Bundle was evaluated based on 5 elements: central venous catheter removal within 24 hours, appropriate antifungal therapy, ophthalmologic examination, follow-up blood cultures, and antifungal treatment for ≥2 weeks after clearance. Patients were categorized into high (4–5 items) and low (0–3 items) compliance groups. The primary and secondary outcomes were defined as 30-day survival and the development of endophthalmitis, with propensity score matching used to adjust for potential confounders.
Results. Among 230 patients, 160 (69.5%) were classified into the high compliance group, which exhibited significantly lower 30-day mortality than the low compliance group (8.8% vs 57.1%, P < .01). Even after matching, the high compliance group remained independently associated with improved survival (hazard ratio [HR]: 0.15; 95% confidence interval [CI]: .08–.30). C. albicans (HR: 1.95; 95% CI: 1.01–3.52) and central line-associated bloodstream infection (HR: 2.63; 95% CI: 1.35–5.12) were associated with the fatal outcome. Endophthalmitis involved 23.6% of the patients, being associated with C. albicans (odds ratio [OR]: 8.18; 4.46–19.30) and central line-associated bloodstream infection (OR: 2.69; 1.08–6.70).
Conclusions. Strict compliance to the Candida Care Bundle significantly improves survival, underscoring its importance in candidemia management. en-copyright= kn-copyright= en-aut-name=AkazawaHidemasa en-aut-sei=Akazawa en-aut-mei=Hidemasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FukushimaShinnosuke en-aut-sei=Fukushima en-aut-mei=Shinnosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HiguchiToshie en-aut-sei=Higuchi en-aut-mei=Toshie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyoshiTomoko en-aut-sei=Miyoshi en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakanoYasuhiro en-aut-sei=Nakano en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=AkamatsuYukinobu en-aut-sei=Akamatsu en-aut-mei=Yukinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HarukiYuto en-aut-sei=Haruki en-aut-mei=Yuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=IwamotoYoshitaka en-aut-sei=Iwamoto en-aut-mei=Yoshitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TanakaShuichi en-aut-sei=Tanaka en-aut-mei=Shuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=FujisatoShun en-aut-sei=Fujisato en-aut-mei=Shun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=AkoSoichiro en-aut-sei=Ako en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 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=13 ORCID= affil-num=1 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of General Internal Medicine, Okayama Red Cross Hospital kn-affil= affil-num=4 en-affil=Center for Medical Education and Internationalization, Kyoto University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Microbiology Division, Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of General Medicine, Tottori Municipal Hospital kn-affil= affil-num=8 en-affil=Department of Pharmacy, Tsuyama Chuo Hospital kn-affil= affil-num=9 en-affil=Department of General Medicine, NHO Okayama Medical Center kn-affil= affil-num=10 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Pharmacy, Okayama Rousai Hospital kn-affil= affil-num=12 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= en-keyword=candida bundle kn-keyword=candida bundle en-keyword=candidemia kn-keyword=candidemia en-keyword=endophthalmitis kn-keyword=endophthalmitis en-keyword=prognosis kn-keyword=prognosis en-keyword=propensity score matching kn-keyword=propensity score matching END start-ver=1.4 cd-journal=joma no-vol=113 cd-vols= no-issue=4 article-no= start-page=117030 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=Time to positivity for differentiating blood culture contamination: A 20-hour cutoff for major contaminants en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Blood culture remains the gold standard for diagnosing bacteremia; however, contamination inevitably occurs in 2-3% of cases, requiring differentiation between true bacteremia and contamination. Although time to positivity (TTP) aids in this clinical decision, with detection after 24 hours generally indicating contamination, technological advances in blood culture systems may have shortened this threshold interval.
Methods: This study retrospectively analyzed blood culture data in our hospital from April 2023 to January 2025 to determine the optimal TTP cutoff. Patients with positive blood cultures for major contaminating bacteria were included. Cases were classified as true bacteremia or contamination based on a comprehensive chart review conducted by the antimicrobial stewardship audit, and TTP was compared between the groups. Sensitivity, specificity, and Youden index at various TTP cutoffs were utilized to determine the optimal threshold using the receiver operating characteristic curve analysis.
Results: Seventy-one patients were enrolled, with 34 cases classified as true bacteremia and 37 as contamination. Identified bacteria included coagulase-negative staphylococci (70.4%), viridans group streptococci (18.3%), and others (11.3%). The median TTP was significantly shorter in the true bacteremia group compared with the contamination group (18.6 vs.25.8 hours, p < 0.001). In the contamination group, 43.2% of the cases demonstrated positive growth within 24 hours. Based on sensitivity, specificity, and Youden index, the optimal threshold was estimated to be 20 hours. A subgroup analysis of the CNS-only cohort yielded concordant results.
Conclusion: This study suggests that a 20-hour TTP threshold could help effectively differentiate true bacteremia from contamination in current clinical settings. en-copyright= kn-copyright= en-aut-name=ManabeYohei en-aut-sei=Manabe en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FukushimaShinnosuke en-aut-sei=Fukushima en-aut-mei=Shinnosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakamotoKenta en-aut-sei=Nakamoto en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OguniKohei en-aut-sei=Oguni en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AkazawaHidemasa en-aut-sei=Akazawa en-aut-mei=Hidemasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FujitaYasushi en-aut-sei=Fujita en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KiguchiTakashi en-aut-sei=Kiguchi en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= affil-num=1 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Nursing, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Nursing, Okayama University Hospital kn-affil= affil-num=9 en-affil=Microbiology Division, Clinical Laboratory, Okayama University Hospital kn-affil= en-keyword=Bacteremia kn-keyword=Bacteremia en-keyword=Blood stream infection kn-keyword=Blood stream infection en-keyword=Contamination kn-keyword=Contamination en-keyword=Incubation time kn-keyword=Incubation time en-keyword=Time to positivity kn-keyword=Time to positivity END start-ver=1.4 cd-journal=joma no-vol=190 cd-vols= no-issue=6 article-no= start-page=90 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=Prognostic Value of Serum (1→3)-β-D-Glucan Levels in Patients with Candidemia Stratified by Compliance with Candida Bundle: A Multicenter Retrospective Cohort Study (2016–2023) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Candidemia is a severe systemic infection with a high mortality risk. While β-D-glucan (BDG) serves as a diagnostic biomarker, its prognostic value in candidemia, particularly in association with Candida bundle compliance, remains unclear.
Methods In this retrospective multicenter cohort study, we evaluated 96 patients with candidemia across nine Japanese hospitals between 2016 and 2023. Candida bundle compliance was assessed using five key components: central venous catheter removal within 24 h of diagnosis, appropriate initial antifungal therapy, ophthalmologic examination, follow-up blood cultures until clearance, and antifungal therapy for at least two weeks post-clearance. Analyses stratified patients by serum BDG status (positive/negative) and compliance with the Candida bundle (high: 4–5 points; low: 0–3 points). The primary outcome was 30-day mortality, and the secondary outcome was defined as endophthalmitis incidence.
Results Of 96 eligible patients with candidemia, 70 (72.9%) were BDG-positive and 26 (27.1%) were BDG-negative. The overall 30-day mortality was 17.7%. Among BDG-positive patients, 15 (21.4%) died, while 2 (7.7%) died in BDG-negative cohorts (p = 0.09). Serum BDG positivity demonstrated a statistically significant association with decreased survival rates in the low bundle adherence group (p = 0.02), whereas this correlation was not observed among patients in the high-compliance cohort (p = 0.66). Endophthalmitis occurred in 25.0% of patients, without significant correlation to serum BDG status. C. albicans was associated with a significantly higher incidence of endophthalmitis compared with non-albicans species (45.7% vs. 8.9%).
Conclusions Serum BDG positivity potentially correlates with worse survival in candidemia, particularly in patients with low bundle compliance. This emphasizes the importance of adherence to standardized Candida management protocols for optimizing patient outcomes. en-copyright= kn-copyright= en-aut-name=AkazawaHidemasa en-aut-sei=Akazawa en-aut-mei=Hidemasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FukushimaShinnosuke en-aut-sei=Fukushima en-aut-mei=Shinnosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HiguchiToshie en-aut-sei=Higuchi en-aut-mei=Toshie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyoshiTomoko en-aut-sei=Miyoshi en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakanoYasuhiro en-aut-sei=Nakano en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=AkamatsuYukinobu en-aut-sei=Akamatsu en-aut-mei=Yukinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HarukiYuto en-aut-sei=Haruki en-aut-mei=Yuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=IwamotoYoshitaka en-aut-sei=Iwamoto en-aut-mei=Yoshitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TanakaShuichi en-aut-sei=Tanaka en-aut-mei=Shuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=FujisatoShun en-aut-sei=Fujisato en-aut-mei=Shun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=AkoSoichiro en-aut-sei=Ako en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 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=13 ORCID= affil-num=1 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of General Internal Medicine, Okayama Red Cross Hospital kn-affil= affil-num=4 en-affil=Center for Medical Education and Internationalization, Kyoto University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Microbiology Division, Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of General Medicine, Tottori Municipal Hospital kn-affil= affil-num=8 en-affil=Department of Pharmacy, Tsuyama Chuo Hospital kn-affil= affil-num=9 en-affil=Department of General Medicine, NHO Okayama Medical Center kn-affil= affil-num=10 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Pharmacy, Okayama Rousai Hospital kn-affil= affil-num=12 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= en-keyword=Candidemia kn-keyword=Candidemia en-keyword=Prognosis kn-keyword=Prognosis en-keyword=β-D-glucan kn-keyword=β-D-glucan en-keyword=Candida bundle kn-keyword=Candida bundle en-keyword=Endophthalmitis kn-keyword=Endophthalmitis END start-ver=1.4 cd-journal=joma no-vol=30 cd-vols= no-issue=7 article-no= start-page=oyaf201 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202507 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Pharmacovigilance study for the identification of mogamulizumab-induced immune-related adverse events using a real-world database en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Mogamulizumab is a humanized anti-CCR4 monoclonal antibody used for relapsed/refractory adult T-cell leukemia, cutaneous T-cell lymphoma, and/or Sézary syndrome. Reports of immune-related adverse events (irAEs) in these patients are increasing, and the association between irAEs and mogamulizumab remains to be elucidated. This study aimed to evaluate the association between mogamulizumab and immune-related adverse events (irAEs), as well as to characterize the irAEs associated with mogamulizumab using data from a large-scale spontaneous reporting system.
Methods: We performed an exploratory hypothesis-generating analysis of patients from 1967 to September 2023 using VigiBase, a World Health Organization spontaneous adverse event reporting system database. We performed a disproportionality analysis and determined the reporting odds ratios and information components between the drugs of interest and each irAE.
Results: Mogamulizumab was associated with some irAEs, including myocarditis, severe cutaneous adverse reactions, hepatitis, and myositis. Mogamulizumab exhibited significantly higher reporting rates of these 4 irAEs compared to the anticancer agents other than mogamulizumab. Conversely, the reporting rate of other irAEs, including endocrine autoimmune diseases induced by immune checkpoint inhibitors, was not significant in patients who received mogamulizumab.
Conclusions: Mogamulizumab is associated with irAEs, including myocarditis, severe cutaneous adverse reactions, hepatitis, and myositis. en-copyright= kn-copyright= en-aut-name=MiyataKoji en-aut-sei=Miyata en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Izawa-IshizawaYuki en-aut-sei=Izawa-Ishizawa en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NiimuraTakahiro en-aut-sei=Niimura en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YoshiokaToshihiko en-aut-sei=Yoshioka en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HyodoMizusa en-aut-sei=Hyodo en-aut-mei=Mizusa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ItokazuShuto en-aut-sei=Itokazu en-aut-mei=Shuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MiyataTatsumi en-aut-sei=Miyata en-aut-mei=Tatsumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AizawaFuka en-aut-sei=Aizawa en-aut-mei=Fuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YagiKenta en-aut-sei=Yagi en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KawadaKei en-aut-sei=Kawada en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=HamanoHirofumi en-aut-sei=Hamano en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=ZamamiYoshito en-aut-sei=Zamami en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=GodaMitsuhiro en-aut-sei=Goda en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=IshizawaKeisuke en-aut-sei=Ishizawa en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Clinical Pharmacology and Therapeutics, Graduate School of Biomedical Sciences, Tokushima University kn-affil= affil-num=2 en-affil=Department of Clinical Pharmacology and Therapeutics, Graduate School of Biomedical Sciences, Tokushima University kn-affil= affil-num=3 en-affil=Department of Clinical Pharmacology and Therapeutics, Graduate School of Biomedical Sciences, Tokushima University kn-affil= affil-num=4 en-affil=Department of Clinical Pharmacology and Therapeutics, Graduate School of Biomedical Sciences, Tokushima University kn-affil= affil-num=5 en-affil=Department of Clinical Pharmacology and Therapeutics, Graduate School of Biomedical Sciences, Tokushima University kn-affil= affil-num=6 en-affil=Department of Clinical Pharmacology and Therapeutics, Graduate School of Biomedical Sciences, Tokushima University kn-affil= affil-num=7 en-affil=Department of Clinical Pharmacology and Therapeutics, Graduate School of Biomedical Sciences, Tokushima University kn-affil= affil-num=8 en-affil=Department of Clinical Pharmacology and Therapeutics, Graduate School of Biomedical Sciences, Tokushima University kn-affil= affil-num=9 en-affil=Department of Clinical Pharmacology and Therapeutics, Graduate School of Biomedical Sciences, Tokushima University kn-affil= affil-num=10 en-affil=Department of Clinical Pharmacology and Therapeutics, Graduate School of Biomedical Sciences, Tokushima University kn-affil= affil-num=11 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=13 en-affil=Department of Clinical Pharmacology and Therapeutics, Graduate School of Biomedical Sciences, Tokushima University kn-affil= affil-num=14 en-affil=Department of Clinical Pharmacology and Therapeutics, Graduate School of Biomedical Sciences, Tokushima University kn-affil= en-keyword=irAEs kn-keyword=irAEs en-keyword=mogamulizumab kn-keyword=mogamulizumab en-keyword=VigiBase kn-keyword=VigiBase en-keyword=disproportionality analysis kn-keyword=disproportionality analysis en-keyword=sézary syndrome kn-keyword=sézary syndrome END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=376 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260104 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Oral Health-Related Quality of Life and Self-Reported Oral Health Status Are Associated with Change in Self-Reported Depression Status: A Cohort Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: Oral health-related quality of life (OHRQoL) may influence mental health outcomes, yet longitudinal evidence on its association with depression remains limited. This study aimed to examine whether oral health status and OHRQoL are associated with a change in self-reported depression status among adults in Japan. Methods: We analyzed data from the Japan COVID-19 and Society Internet Survey (JACSIS), conducted in 2022 and 2023. A total of 15,068 participants aged ≥20 years without depression at baseline were included. Depression status was identified by self-reported measures between the two survey waves. Logistic regression models estimated odds ratios (ORs) and 95% confidence intervals (CIs) for change in self-reported depression status in relation to OHRQoL and oral health status, adjusting for sociodemographic and behavioral factors. Results: During follow-up, 218 participants (1.45%) reported a change in self-reported depression status. Poorer OHRQoL was significantly associated with a change in self-reported depression status (OR: 1.018; 95% CI: 1.001–1.036; p = 0.039). Additional risk factors included younger age (OR: 0.974; 95% CI: 0.964–0.985), participation in hobbies and cultural activities (OR: 2.224; 95% CI: 1.498–3.302), habitual use of sleeping pills or anxiolytics (current use OR: 3.512; 95% CI: 2.267–5.442), increased loneliness (OR: 1.217; 95% CI: 1.140–1.299), lower life satisfaction (OR: 0.900; 95% CI: 0.836–0.969), and poor self-rated health (OR: 2.921; 95% CI: 1.810–4.715). Conclusions: Impaired OHRQoL was associated with a change in self-reported depression status, potentially through psychosocial mechanisms. These findings suggest that oral health and OHRQoL may be relevant factors to consider in integrated oral and mental health approaches in clinical practice. en-copyright= kn-copyright= en-aut-name=TakeuchiNoriko en-aut-sei=Takeuchi en-aut-mei=Noriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MaruyamaTakayuki en-aut-sei=Maruyama en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ToyamaNaoki en-aut-sei=Toyama en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KatsubeYuzuki en-aut-sei=Katsube en-aut-mei=Yuzuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TabuchiTakahiro en-aut-sei=Tabuchi en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=EkuniDaisuke en-aut-sei=Ekuni en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Preventive Dentistry, Division of Dentistry, Medical Development Field, Okayama University kn-affil= affil-num=2 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Dental School, Okayama University kn-affil= affil-num=5 en-affil=Division of Epidemiology, School of Public Health, Tohoku University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=oral health-related quality of life kn-keyword=oral health-related quality of life en-keyword=depression status kn-keyword=depression status en-keyword=cohort study kn-keyword=cohort study END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue= article-no= start-page=100511 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202503 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Genetic variability in Neisseria meningitidis strains isolated in a Japanese hospital en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: Neisseria meningitidis is a significant pathogen causing invasive meningococcal disease, posing clinical and public health concerns worldwide. This study aimed to investigate the genetic characteristics of N. meningitidis clinical isolates at Okayama University Hospital in Japan.
Methods: Between 2018 and 2023, five clinical strains were isolated, of which three were subjected to the antimicrobial susceptibility testing and whole genetic analysis using MiSeq platform (Illumina, San Diego, CA, USA).
Results: One non-groupable isolate, belonging to sequence types (STs)-11026 (ST-32 complex), exhibited non-susceptibility to penicillin G, with a five-mutation pattern (F504L, A510V, I515V, H541N, and I566V) in the penA amino acid sequence and additional mutations (XXXIV and N513Y) characteristic of a mosaic penA gene. The other two isolates, ST-1655 (ST-23 complex) with serogroup Y and ST-2057 with serogroup B, were susceptible to penicillin G, neither of which contained the five-mutation pattern. Levofloxacin resistance was observed in two isolates carrying the T91I mutation in the gyrA protein.
Conclusion: Our findings suggest the presence of antimicrobial-resistant N. meningitidis in Japan, underscoring the necessity for continuous local surveillance. Additional research is crucial for clarifying the ongoing spread of resistance mechanisms and for establishing effective countermeasures to reduce the clinical burden of invasive meningococcal disease. en-copyright= kn-copyright= en-aut-name=GotohKazuyoshi en-aut-sei=Gotoh en-aut-mei=Kazuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FukushimaShinnosuke en-aut-sei=Fukushima en-aut-mei=Shinnosuke 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=TsujiShuma en-aut-sei=Tsuji en-aut-mei=Shuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=MatsushitaOsamu en-aut-sei=Matsushita en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Medical Laboratory Science, Okayama University Graduate School of Health Sciences kn-affil= affil-num=2 en-affil=Department of Bacteriology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Medical Laboratory Science, Okayama University Graduate School of Health Sciences kn-affil= affil-num=5 en-affil=Microbiology Division, Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Bacteriology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Antimicrobial resistance kn-keyword=Antimicrobial resistance en-keyword=Invasive meningococcal disease kn-keyword=Invasive meningococcal disease en-keyword=Drug-resistant gene kn-keyword=Drug-resistant gene en-keyword=Genome sequence kn-keyword=Genome sequence END start-ver=1.4 cd-journal=joma no-vol=137 cd-vols= no-issue=3 article-no= start-page=126 end-page=131 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A survey of college students' knowledge and awareness of hereditary cancer kn-title=遺伝性腫瘍に関する大学生の知識と意識調査 en-subtitle= kn-subtitle= en-abstract= kn-abstract= Genomic information plays a critical role in the diagnosis and treatment of various diseases, as well as in the management of asymptomatic individuals. This study assessed the knowledge and understanding of genetics and hereditary cancer among college students who received cancer education in Japan. The study subjects were students from fields such as education, medicine, law, and economics who participated during the period from February to December 2023. The students attended in-person lectures on genomic medicine, and they were then asked to complete an anonymous survey via Google Forms. Over 90% of the participants reported understanding the content of the lectures, and >80% indicated that they found the lecture's content understandable at a junior high school level. Over 60% felt that the appropriate time to begin such education would be in late elementary or junior high school. These results indicate a high level of acceptance of hereditary cancer education among young people. However, challenges remain in their understanding of the roles of genetic factors in cancer development and the mechanisms by which inheritance and phenotype are manifested. The relevant educational programs need to be further refined and strengthened. en-copyright= kn-copyright= en-aut-name=SogawaReimi en-aut-sei=Sogawa en-aut-mei=Reimi kn-aut-name=十川麗美 kn-aut-sei=十川 kn-aut-mei=麗美 aut-affil-num=1 ORCID= en-aut-name=WadaTakahito en-aut-sei=Wada en-aut-mei=Takahito kn-aut-name=和田敬仁 kn-aut-sei=和田 kn-aut-mei=敬仁 aut-affil-num=2 ORCID= en-aut-name=HirasawaAkira en-aut-sei=Hirasawa en-aut-mei=Akira kn-aut-name=平沢晃 kn-aut-sei=平沢 kn-aut-mei=晃 aut-affil-num=3 ORCID= en-aut-name=KumamotoKensuke en-aut-sei=Kumamoto en-aut-mei=Kensuke kn-aut-name=隈元謙介 kn-aut-sei=隈元 kn-aut-mei=謙介 aut-affil-num=4 ORCID= en-aut-name=OhmoriIori en-aut-sei=Ohmori en-aut-mei=Iori kn-aut-name=大守伊織 kn-aut-sei=大守 kn-aut-mei=伊織 aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Clinical Genetics and Genomic Medicine, Kagawa University Hospital kn-affil=香川大学医学部附属病院 臨床遺伝ゲノム診療科 affil-num=2 en-affil=Department of Genomic Medicine, Kyoto University Graduate School of Medicine kn-affil=京都大学大学院医学研究科 ゲノム医療学 affil-num=3 en-affil=Department of Clinical Genomic Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学学術研究院医歯薬学域 臨床遺伝医療学 affil-num=4 en-affil=Department of Clinical Genetics and Genomic Medicine, Kagawa University Hospital kn-affil=香川大学医学部附属病院 臨床遺伝ゲノム診療科 affil-num=5 en-affil=Special Needs Education, Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 特別支援教育 en-keyword=遺伝性腫瘍 (hereditary cancer) kn-keyword=遺伝性腫瘍 (hereditary cancer) en-keyword=ゲノム教育 (genome education) kn-keyword=ゲノム教育 (genome education) en-keyword=市民教育 (public education) kn-keyword=市民教育 (public education) en-keyword=学校教育 (school education) kn-keyword=学校教育 (school education) END start-ver=1.4 cd-journal=joma no-vol=137 cd-vols= no-issue=3 article-no= start-page=118 end-page=125 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The results of COVID-19 antibody testing studies in Bizen, Japan kn-title=備前市における新型コロナウイルス感染症の抗体検査に関する研究の成果報告 en-subtitle= kn-subtitle= en-abstract= kn-abstract= We conducted two prospective cohort studies (June 2022–March 2023 and Nov 2023–Jan 2024) of 1,899 and 445 residents and other individuals who are affiliated with institutions in the city of Bizen in Japan's Okayama prefecture (population 32,320 as of 2020). We measured the subjects' titers of antibodies against SARS-CoV-2, evaluated changes in their antibody titers, and assessed the associations of the titers with the subjects' vaccination status, infection, and COVID-19 status/severity. This report summarizes the two studies' findings. These prospective studies based on a wide age range in a general population provide information that can be used to determine the appropriate timing of vaccination during a pandemic. en-copyright= kn-copyright= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name=頼藤貴志 kn-aut-sei=頼藤 kn-aut-mei=貴志 aut-affil-num=1 ORCID= en-aut-name=SasakiAyako en-aut-sei=Sasaki en-aut-mei=Ayako kn-aut-name=佐々木綾子 kn-aut-sei=佐々木 kn-aut-mei=綾子 aut-affil-num=2 ORCID= en-aut-name=MatsumotoNaomi en-aut-sei=Matsumoto en-aut-mei=Naomi kn-aut-name=松本尚美 kn-aut-sei=松本 kn-aut-mei=尚美 aut-affil-num=3 ORCID= en-aut-name=KadowakiTomoka en-aut-sei=Kadowaki en-aut-mei=Tomoka kn-aut-name=門脇知花 kn-aut-sei=門脇 kn-aut-mei=知花 aut-affil-num=4 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name=三橋利晴 kn-aut-sei=三橋 kn-aut-mei=利晴 aut-affil-num=5 ORCID= en-aut-name=TakaoSoshi en-aut-sei=Takao en-aut-mei=Soshi kn-aut-name=高尾総司 kn-aut-sei=高尾 kn-aut-mei=総司 aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Science, Okayama University kn-affil=岡山大学学術研究院医歯薬学域 疫学・衛生学 affil-num=2 en-affil=Kurashiki City Public Health Center kn-affil=倉敷市保健所 affil-num=3 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Science, Okayama University kn-affil=岡山大学学術研究院医歯薬学域 疫学・衛生学 affil-num=4 en-affil=Center for Public Health Action in Applied Epidemiology, National Institute of Infectious Diseases kn-affil=国立感染症研究所 応用疫学研究センター affil-num=5 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil=岡山大学病院 新医療研究開発センター affil-num=6 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Science, Okayama University kn-affil=岡山大学学術研究院医歯薬学域 疫学・衛生学 en-keyword=COVID-19 kn-keyword=COVID-19 en-keyword=ワクチン (vaccination) kn-keyword=ワクチン (vaccination) en-keyword=抗体価 (antibody titer) kn-keyword=抗体価 (antibody titer) en-keyword=感染 (infection) kn-keyword=感染 (infection) 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=20251117 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Genomic Profiling of Pediatric Solid Tumors With a Dual DNA/RNA Panel: JCCG-TOP2 Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=To develop an optimized genomic medicine platform for pediatric cancers, a nationwide cancer genome profiling project was conducted from January 2022 to February 2023 in collaboration with the Japan Children's Cancer Group. This prospective observational study analyzed matched blood and FFPE tumor samples from patients aged 0–29 years with solid tumors. Genomic analysis used the TOP2 hybrid capture–enrichment system, targeting 737 and 455 genes in the DNA and RNA panels, along with allele-specific genome copy number alterations. A total of 210 patients from 50 institutions were enrolled across Japan (median age, 8 years; range, 0–25). Of these, 154 (77%) were enrolled at diagnosis or during/after initial treatment and 56 (27%) at disease progression or relapse. The TOP2 findings had great benefits in clarifying the diagnosis of pediatric solid tumors. Among the 204 patients with genomic results, 147 (72%) had potentially actionable findings, including diagnostic, prognostic, and therapeutic findings in 111 (54%), 61 (30%), and 64 (31%), respectively. Oncogenic fusions were noted in 45 (23%) patients. A copy number alteration was identified in at least one genomic region in 170 (83%) patients. Two patients exhibited a high tumor mutation burden. Seventeen (8%) patients harbored a germline pathogenic/likely pathogenic variant in cancer-predisposing genes. This study highlighted the feasibility of implementing a nationwide precision medicine platform and the clinical utility of the TOP2 system for pediatric cancers. The results support the integration of genomic data into the standard clinical care of pediatric patients with cancer, both at diagnosis and at relapse. en-copyright= kn-copyright=

Tube-Related Intussusception: A Case Report and Review of 80 Previously Reported Cases en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report a rare case of ileus tube-related intussusception in an adult. A 56-year-old man with adhesive bowel obstruction was treated with a nasointestinal ileus tube. Although his condition initially improved, persistent abdominal pain led to the diagnosis of intussusception via CT imaging. Manual repositioning of the tube resolved the intussusception without the need for bowel resection. A review of 80 previously reported cases of ileus tube-associated intussusception (total 81 cases, 95 lesions) highlighted the timing of onset, treatment strategies, and precautions. Early detection and diagnosis are crucial to prevent severe complications and preserve bowel function. en-copyright= kn-copyright= en-aut-name=TsujiiTeruyuki en-aut-sei=Tsujii en-aut-mei=Teruyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsudaTatsuo en-aut-sei=Matsuda en-aut-mei=Tatsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KimuraYuji en-aut-sei=Kimura en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KatsubeRyoichi en-aut-sei=Katsube en-aut-mei=Ryoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IwadouHironori en-aut-sei=Iwadou en-aut-mei=Hironori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FunabikiSadami en-aut-sei=Funabiki en-aut-mei=Sadami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KamikawaYasuaki en-aut-sei=Kamikawa en-aut-mei=Yasuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MatsudaTadakazu en-aut-sei=Matsuda en-aut-mei=Tadakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Surgery, Matsuda Hospital kn-affil= affil-num=2 en-affil=Department of Surgery, Matsuda Hospital kn-affil= affil-num=3 en-affil=Department of Surgery, Matsuda Hospital kn-affil= affil-num=4 en-affil=Department of Surgery, Matsuda Hospital kn-affil= affil-num=5 en-affil=Department of Surgery, Matsuda Hospital kn-affil= affil-num=6 en-affil=Department of Surgery, Matsuda Hospital kn-affil= affil-num=7 en-affil=Department of Surgery, Matsuda Hospital kn-affil= affil-num=8 en-affil=Department of Surgery, Matsuda Hospital kn-affil= en-keyword=nasointestinal ileus tube kn-keyword=nasointestinal ileus tube en-keyword=intussusception kn-keyword=intussusception en-keyword=small bowel obstruction kn-keyword=small bowel obstruction en-keyword=enterectomy kn-keyword=enterectomy en-keyword=conservative treatment kn-keyword=conservative treatment END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=6 article-no= start-page=463 end-page=468 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=MRI Images of a Case of Adenocarcinoma, Human Papillomavirus-Independent, Mesonephric Type, of the Uterine Cervix en-subtitle= kn-subtitle= en-abstract= kn-abstract=We present a case of a woman in her 70s who was diagnosed with mesonephric adenocarcinoma of the uterine cervix, following biopsy and surgery.

The lesion showed intermediate signal intensity on T2-weighted images, diffusion restriction, and early contrast enhancement weaker than that of the myometrium, followed by washout on contrast-enhanced imaging. The circumferential growth pattern with the lateral wall predominance and its imaging characteristics may suggest this rare entity be routinely included in the differential diagnosis of cervical cancers. en-copyright= kn-copyright= en-aut-name=AsanoYudai en-aut-sei=Asano en-aut-mei=Yudai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishiharaChika en-aut-sei=Nishihara en-aut-mei=Chika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KitayamaTakahiro en-aut-sei=Kitayama en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OkawaNanako en-aut-sei=Okawa en-aut-mei=Nanako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MakimotoSatoko en-aut-sei=Makimoto en-aut-mei=Satoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=KojimaKatsuhide en-aut-sei=Kojima en-aut-mei=Katsuhide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SugiharaHanako en-aut-sei=Sugihara en-aut-mei=Hanako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=IdaNaoyuki en-aut-sei=Ida en-aut-mei=Naoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 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=11 ORCID= affil-num=1 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Obstetrics and Gynecology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Obstetrics and Gynecology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Pathology, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=mesonephric adenocarcinoma kn-keyword=mesonephric adenocarcinoma en-keyword=cervical cancer kn-keyword=cervical cancer en-keyword=MRI imaging characteristics kn-keyword=MRI imaging characteristics en-keyword=HPV-independent adenocarcinoma kn-keyword=HPV-independent adenocarcinoma END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=6 article-no= start-page=457 end-page=461 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=Exacerbation of Proteinuria in a Patient with Behçet’s Disease and IgA Nephropathy Following Colchicine Discontinuation en-subtitle= kn-subtitle= en-abstract= kn-abstract=This case involves a 23-year-old male who was diagnosed with Behçet’s disease 5 years ago and managed with colchicine. Two months ago, he underwent renal biopsy due to abnormal urinalysis and kidney dysfunction, leading to a diagnosis of IgA nephropathy. He subsequently underwent tonsillectomy followed by glucocorticoid pulse therapy. However, after the tonsillectomy, discontinuing colchicine led to increased proteinuria, despite the glucocorticoid pulse therapy. Upon reintroducing colchicine, urinary protein excretion decreased, achieving incomplete remission. These findings suggest that colchicine may be effective in decreasing proteinuria in patients with Behçet’s disease complicated by IgA nephropathy. en-copyright= kn-copyright= en-aut-name=AsakawaTomohiko en-aut-sei=Asakawa en-aut-mei=Tomohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=KatayamaYu en-aut-sei=Katayama en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakurabuYoshimasa en-aut-sei=Sakurabu en-aut-mei=Yoshimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatayamaKatsuyoshi en-aut-sei=Katayama en-aut-mei=Katsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OnishiYasuhiro en-aut-sei=Onishi en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=Matsuoka-UchiyamaNatsumi en-aut-sei=Matsuoka-Uchiyama en-aut-mei=Natsumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakeuchiHidemi en-aut-sei=Takeuchi en-aut-mei=Hidemi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TanakaKeiko en-aut-sei=Tanaka en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 ORCID= en-aut-name=UmebayashiRyoko en-aut-sei=Umebayashi en-aut-mei=Ryoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=TakemotoRika en-aut-sei=Takemoto en-aut-mei=Rika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 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=13 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Behçet’s disease kn-keyword=Behçet’s disease en-keyword=IgA nephropathy kn-keyword=IgA nephropathy en-keyword=colchicine kn-keyword=colchicine END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=6 article-no= start-page=451 end-page=455 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=Recurrence of FVIII Inhibitor during Surgery in a Patient with Severe Hemophilia A Receiving Emicizumab Prophylaxis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Emicizumab, a bispecific monoclonal antibody, benefits patients with severe hemophilia A. It alters laboratory assessments of coagulation activity, requiring anti-idiotype monoclonal antibodies for accurate monitoring. A 64-year-old man, receiving emicizumab regularly, was admitted for laminoplasty. We planned to use FVIII replacement during the perioperative period after confirming the disappearance of inhibitors, monitoring coagulation activity with anti-idiotype monoclonal antibodies. Activated partial thromboplastin time was prolonged on postoperative day 2, prompting an immediate switch to eptacog alfa. The patient recovered without bleeding. This case underscores the necessity of anti-idiotype monoclonal antibodies for accurate monitoring. en-copyright= kn-copyright= en-aut-name=HagiharaMoe en-aut-sei=Hagihara en-aut-mei=Moe 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=HayashinoKenta en-aut-sei=Hayashino en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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=5 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=6 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=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=FujiwaraHideaki en-aut-sei=Fujiwara en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 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=11 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=12 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 Neurological Surgery, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Neurological Surgery, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Neurological Surgery, 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= affil-num=9 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=11 en-affil=Division of Transfusion and Cell Therapy, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= en-keyword=emicizumab kn-keyword=emicizumab en-keyword=eptacog alfa kn-keyword=eptacog alfa en-keyword=hemophilia A kn-keyword=hemophilia A en-keyword=inhibitor kn-keyword=inhibitor en-keyword=anti-idiotype monoclonal antibodies to emicizumab kn-keyword=anti-idiotype monoclonal antibodies to emicizumab END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=6 article-no= start-page=445 end-page=449 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=Perioperative Team Management Was Beneficially Associated with Prolonged Postoperative Hospital Stays after Long Lower-Abdominal Surgeries en-subtitle= kn-subtitle= en-abstract= kn-abstract=Our hospital began a PERIO program (perioperative patient management by a multi-disciplinary team from multiple departments) in 2016 to improve patient outcomes. We retrospectively analyzed the clinical effects of the PERIO program regarding the postoperative hospital stay (PHS) in the patients aged ≥ 18 years who underwent long lower-abdominal surgery at our hospital during the period April 2019 to March 2023. We excluded the cases of patients whose general anesthesia use was < 8 h, those for whom another surgery was performed simultaneously at another site, and emergency surgeries. The outcome was prolonged PHS, defined as exceeding the scheduled number of days specified in the patient’s clinical pathway. Among the 480 patients, prolonged PHS was observed for 270 patients (56.3%). In a multivariate logistic regression using advanced age, sex, high-risk general state, surgery requiring colon resection, serious adverse events (SAEs), and PERIO use, the following were associated with prolonged PHS: advance age (odds ratio [OR] 4.91, 95% confidence interval [CI]: 2.68-8.99, p=0.01), surgery requiring colon resection (OR 4.91, 95%CI: 2.68-8.99, p<0.001), SAE (OR 18.7, 95%CI: 7.22-48.2, p<0.001), and PERIO (OR 0.25, 95%CI: 0.13-0.47, p<0.001). The use of the PERIO program was thus beneficially associated with PHS after long lower-abdominal surgery. en-copyright= kn-copyright= en-aut-name=MatsumiJunya en-aut-sei=Matsumi en-aut-mei=Junya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Anesthesiology and Intensive Care Medicine, National Cancer Center Hospital kn-affil= en-keyword=hospital stay kn-keyword=hospital stay en-keyword=ERAS kn-keyword=ERAS en-keyword=surgery kn-keyword=surgery en-keyword=cancer kn-keyword=cancer en-keyword=perioperative management kn-keyword=perioperative management END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=6 article-no= start-page=437 end-page=444 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=Frailty at 1 Month before ICU Admission Poses a Hospital Mortality Risk in Cancer Survivors whose Condition Has Deteriorated due to Medical Factors en-subtitle= kn-subtitle= en-abstract= kn-abstract=The optimal indications for intensive care unit (ICU) treatment for critically ill cancer survivors whose condition has deteriorated due to medical factors are unclear. To test our hypothesis that frailty before deterioration was associated with hospital mortality in this patient population, we retrospective analyzed the cases of the patients admitted to the ICU at the National Cancer Center Hospital, Japan (April 2014-March 2022). We excluded patients who underwent surgery within 28 days or were denied critical care within 24 h or admitted after cardiopulmonary arrest. Their Clinical Frailty Scale (CFS) scores at 1 month before ICU admission (Pre-ICU) were obtained. Frailty was defined as CFS scores ≥4 points. We analyzed 298 admissions and observed that the mortality rate at hospital discharge was significantly higher in the frailty group (n=119). A multivariate analysis demonstrated that the following factors were significantly associated with hospital mortality: Pre-ICU frailty (OR 2.00, 95%CI: 1.19-3.36, p=0.009), cancer type (hematological: OR 2.93, 95%CI: 1.42-6.05, p=0.004), and Sequential Organ Failure Assessment score at ICU admission (OR 0.88, 95%CI: 0.82-0.95, p=0.0008). Frailty retrospectively assessed using the CFS at 1 month pre-ICU admission is a risk factor for hospital mortality in these cancer survivors. en-copyright= kn-copyright= en-aut-name=MatsumiJunya en-aut-sei=Matsumi en-aut-mei=Junya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SatoTetsufumi en-aut-sei=Sato en-aut-mei=Tetsufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Anesthesiology and Intensive Care Medicine, National Cancer Center Hospital kn-affil= affil-num=2 en-affil=Department of Anesthesiology and Intensive Care Medicine, National Cancer Center Hospital kn-affil= en-keyword=frailty kn-keyword=frailty en-keyword=cancer survivor kn-keyword=cancer survivor en-keyword=clinical frailty scale kn-keyword=clinical frailty scale en-keyword=cancer kn-keyword=cancer en-keyword=critically ill kn-keyword=critically ill END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=6 article-no= start-page=413 end-page=419 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=COVID-19 and the Risks of Migraine and Headache: A Mendelian Randomization Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Several observational studies suggested that migraine headache attacks were associated with coronavirus disease 2019 (COVID-19). We investigated genetic causal links between COVID-19 phenotypes and the development of headache and migraine, including migraine with aura (MA) and migraine without aura (MO). We conducted a two-sample Mendelian randomization (MR) analysis to estimate the genetic association in European populations. The inverse-variance weighted (IVW) method was used as the main approach in the MR analyses, together with weighted median and MR-Egger methods. We also performed a series of sensitivity tests to assess the robustness of the MR results. The MR results demonstrated that COVID-19 severity, hospitalization, and susceptibility had no causal effect on the risks of headache, migraine, MA, or MO. No horizontal pleiotropy was detected, and the results were robust as supported by the sensitivity analysis findings. Our analyses identified no casual effect of COVID-19 severity, hospitalization, or susceptibility on the risks of headache or migraine in European populations. en-copyright= kn-copyright= en-aut-name=JiangZhiyun en-aut-sei=Jiang en-aut-mei=Zhiyun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=XiYing en-aut-sei=Xi en-aut-mei=Ying kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Clinical Laboratory, The First Affiliated Hospital of Zhengzhou University kn-affil= affil-num=2 en-affil=Department of Clinical Laboratory, The First Affiliated Hospital of Zhengzhou University kn-affil= en-keyword=headache kn-keyword=headache en-keyword=migraine kn-keyword=migraine en-keyword=Mendelian randomization kn-keyword=Mendelian randomization en-keyword=COVID-19 kn-keyword=COVID-19 END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=6 article-no= start-page=405 end-page=412 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=Real-World Outcomes of Anti-Vascular Endothelial Growth Factor Therapy for Neovascular Age-Related Macular Degeneration in Patients Aged 85 or Older en-subtitle= kn-subtitle= en-abstract= kn-abstract=We investigated the treatment outcomes of patients aged ≥85 years with neovascular age-related macular degeneration (nAMD) who received anti-vascular endothelial growth factor (anti-VEGF) therapy using either treat-and-extend (TAE) or pro re nata (PRN) regimens for 1 year in real-world clinical practice. Eighty-five eyes from 85 patients were included. Among them, types 1, 2, and 3 macular neovascularization and polypoidal choroidal vasculopathy were present in 27.1%, 17.6%, 18.8%, and 36.5%, respectively. TAE and PRN regimens were used in 43.5% and 56.5% of patients, respectively. At baseline, the PRN group was older and had worse best-corrected visual acuity (BCVA), greater central retinal thickness, and more intraretinal fluid than the TAE group. In the TAE group, the mean number of injections was 7.6, BCVA improved significantly, and all retinal fluid rates decreased. In the PRN group, the mean number of injections was 3.9, BCVA remained unchanged, and the rates of macular fibrosis and atrophy increased. No serious adverse events were observed in either group. Anti-VEGF therapy was safe for patients aged ≥ 85 years with nAMD, and the TAE regimen effectively improved BCVA in this population. BCVA remained unchanged in the PRN-treated patients, with baseline disease severity and/or undertreatment potentially influencing the outcomes. en-copyright= kn-copyright= en-aut-name=OuchiChihiro en-aut-sei=Ouchi en-aut-mei=Chihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Morizane HosokawaMio en-aut-sei=Morizane Hosokawa en-aut-mei=Mio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KimuraShuhei en-aut-sei=Kimura en-aut-mei=Shuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ShiodeYusuke en-aut-sei=Shiode en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MatobaRyo en-aut-sei=Matoba en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MoritaTetsuro en-aut-sei=Morita en-aut-mei=Tetsuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MorizaneYuki en-aut-sei=Morizane en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=anti-vascular endothelial growth factor therapy kn-keyword=anti-vascular endothelial growth factor therapy en-keyword=neovascular age-related macular degeneration kn-keyword=neovascular age-related macular degeneration en-keyword=age kn-keyword=age en-keyword=treat-and-extend kn-keyword=treat-and-extend en-keyword=pro re nata kn-keyword=pro re nata END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue=1 article-no= start-page=e70052 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251214 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Japanese Adult Day Service Nurses' Bathing Decisions for Persons Requiring Long‐Term Care: A Focused Ethnography en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Adult day services in Japan operate under the Long-Term Care Insurance Law, and care is provided mainly by caregivers. However, because doctors are often not on site, nurses manage the health of the person requiring long-term care. Adult day services provide bathing and functional training; however, although Japanese-style bathing relieves fatigue and brings a sense of well-being, it also entails the risk of bathing accidents for those in need of care. To continue living at home, those in need of care who have difficulty bathing at home must be provided with safe bathing during adult day services and supported in returning home safely. Nurses are responsible for accurately assessing the health status of users and implementing safe bathing. This study aimed to identify how nurses working in adult day services make bathing decisions for home-dwelling persons requiring long-term care.
Method: Qualitative manifest and latent content analyses were performed using a focused ethnography.
Findings: Six themes were identified: ‘gather information to compare with baseline’, ‘make observations based on information from others to understand the big picture’, ‘give persons time to get in shape’, ‘consideration of life at home’, ‘determining the need for medical institutions’ and ‘devise ways to communicate to promote collaboration’.
Conclusions: Adult day service nurses' decisions about whether to bathe persons requiring care are characterised by their emphasis on information from others, consideration of the home living conditions of persons requiring care and their wishes regarding bathing. In addition, based on their observations, they determine the need for cooperation with medical institutions and communicate this information to family members and multiple professions. en-copyright= kn-copyright= en-aut-name=MiyoshiKanako en-aut-sei=Miyoshi en-aut-mei=Kanako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MoriKeiko en-aut-sei=Mori en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= en-keyword=adult day service kn-keyword=adult day service en-keyword=clinical judgement kn-keyword=clinical judgement en-keyword=community kn-keyword=community en-keyword=home care kn-keyword=home care en-keyword=multidisciplinary collaboration kn-keyword=multidisciplinary collaboration en-keyword=nurses kn-keyword=nurses en-keyword=persons requiring care kn-keyword=persons requiring care END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue=4 article-no= start-page=116 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251216 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Drip Fertigation in Greenhouse Eggplant Cultivation: Reducing N2O Emissions and Nitrate Leaching en-subtitle= kn-subtitle= en-abstract= kn-abstract=Drip fertigation (DF) is a sustainable agricultural management technique that optimizes water and nutrient usage, enhances crop productivity, and reduces environmental impact. Herein, we compared the effects of DF and conventional fertilization (CF) with a basal fertilizer on yield, soil inorganic nitrogen dynamics, N2O emissions, and nitrogen leaching during facility-grown eggplant cultivation. The experiment was conducted in a greenhouse from September 2023 to May 2024, with treatments arranged in three rows and three replicates. Soil, gas, and water samples were collected and analyzed throughout the growing season. The results revealed that the DF treatment produced yields comparable to those obtained with the CF treatment while significantly reducing nitrogen and phosphorus inputs. DF effectively prevented excessive nitrogen accumulation in the soil and reduced nitrogen loss through leaching and gas emissions. N2O emissions were significantly lower by more than 60% under DF than under CF. Precise nutrient management in DF suppressed nitrification and denitrification processes, mitigating N2O emissions. DF also significantly reduced nitrogen leaching by more than 70% compared with that in CF. These findings demonstrate that DF effectively enhances agricultural sustainability by improving nutrient use efficiency, reducing greenhouse gas emissions, and minimizing nitrogen leaching during the cultivation of facility-grown eggplant. en-copyright= kn-copyright= en-aut-name=ShiraishiWataru en-aut-sei=Shiraishi en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishimuraShion en-aut-sei=Nishimura en-aut-mei=Shion 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=UenoHideto en-aut-sei=Ueno en-aut-mei=Hideto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Kochi Prefectural Agricultural Research Center kn-affil= affil-num=2 en-affil=Department of Bioresource Production Science, United Graduate School of Agriculture, Ehime 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=Department of Bioresource Production Science, United Graduate School of Agriculture, Ehime University kn-affil= en-keyword=drip fertigation kn-keyword=drip fertigation en-keyword=eggplant kn-keyword=eggplant en-keyword=greenhouse cultivation kn-keyword=greenhouse cultivation en-keyword=nitrogen leaching kn-keyword=nitrogen leaching en-keyword=nitrogen use efficiency kn-keyword=nitrogen use efficiency en-keyword=nitrous oxide emissions kn-keyword=nitrous oxide emissions END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue=1 article-no= start-page=e70144 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250616 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Japanese Multi‐Institution Study of Success Rates of Wire‐Guided Biliary Cannulation During Endoscopic Retrograde Cholangiopancreatography in Relation to Guidewire tip Length (JMIT Study) (With Video) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: Wire-guided cannulation (WGC) reportedly increases the successful biliary cannulation rate and reduces the risk of post-endoscopic retrograde cholangiopancreatography pancreatitis. Currently, various types of guidewires are available. However, the effect of the length of flexible-tip guidewires on the success rate of biliary cannulation under WGC and the rate of adverse events, especially post-endoscopic retrograde cholangiopancreatography pancreatitis, is unclear. The aim of this study was to compare the influence of long-tapered and short-tapered tips of a 0.025-inch guidewire on outcomes in primary selective biliary cannulation.
Methods: Consecutive patients who underwent biliary access under endoscopic retrograde cholangiopancreatography guidance using WGC at 27 high-volume centers in Japan were enrolled in this prospective registration study. The primary outcome was the technical success rate of biliary cannulation. The secondary outcomes were the rates of adverse events, biliary cannulation time, and number of guidewire insertions into the pancreatic duct.
Results: A total of 530 patients underwent biliary cannulation for biliary disease with native papilla between April 2021 and December 2023. The technical success rate of biliary cannulation was 86.1% (161/187) in the long-tip group and 84.3% (289/343) in the short-tip group, indicating no significant differences between the two groups. Although the frequency of post-endoscopic retrograde cholangiopancreatography was not significantly different, the successful biliary cannulation rate without guidewire mis-insertion into the main pancreatic duct was significantly higher in the long tip group (64.7%, 121/187) compared with the short tip group (54.2%, 186/343p = 0.02).
Conclusions: In conclusion, WGC using long-tip guidewires might reduce the risk of guidewire insertion into the main pancreatic duct. en-copyright= kn-copyright= en-aut-name=OguraTakeshi

kn-title=Combination chemotherapy for older patients with unresectable biliary tract cancer: a prospective observational study using propensity-score matched analysis (JON2104-B) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Systemic chemotherapy with gemcitabine plus S-1 (GEM + S-1), GEM + CDDP plus S-1 (GEM + CDDP + S-1), or gemcitabine plus cisplatin (GEM + CDDP) is standard treatment for advanced biliary tract cancer (aBTC). We aimed to evaluate the efficacy and safety of combination chemotherapy in older patients with aBTC.
Methods: This multicenter prospective observational study (JON2104-B, UMIN000045156) included patients aged ≥ 70 years with aBTC. Inverse-probability weighting propensity-score analyses (IPW) were used to compare overall survival (OS) as the primary endpoint and progression-free survival (PFS) across treatment groups.
Results: This study included 305 patients between August 2021 and January 2023. Of them, 75, 131, 26, 52, and 10 received GEM + CDDP + S-1, GEM + CDDP, GEM + S-1, gemcitabine, and S-1; their median ages were 74, 75, 77.5, 80, and 80 years, and approximately 24%, 16.8%, 23.1%, 9.6%, and 0% had G-8 scores of > 14, respectively. GEM + CDDP had a safety profile comparable to that of GEM + CDDP + S-1 but was more toxic than gemcitabine. Per IPW, the hazard ratio (HR) for GEM + CDDP + S-1 versus GEM + CDDP was 0.80 for OS (95% confidence interval [CI], 0.55–1.17) and 0.55 for PFS (95% CI 0.38–0.80). The HR for GEM + CDDP versus gemcitabine was 0.74 for OS (95% CI 0.42–1.29) and 0.79 for PFS (95% CI 0.42–1.49).
Conclusions: GEM + CDDP + S-1 was associated with longer PFS without additional toxicity than GEM + CDDP for fit older patients. However, the OS for both were not statistically different. The efficacies of GEM + CDDP and gemcitabine for vulnerable older patients did not also differ significantly. These findings highlight the importance of vulnerability in patients with aBTC. en-copyright= kn-copyright= en-aut-name=KobayashiSatoshi en-aut-sei=Kobayashi en-aut-mei=Satoshi kn-aut-name=

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=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=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=

kn-title=Current management of neurotrophic receptor tyrosine kinase fusion-positive 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=29 cd-vols= no-issue=10 article-no= start-page=1342 end-page=1353 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250516 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=First-time diagnosis and referral practices for individuals with CKD by primary care physicians: a study 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=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= cd-vols= no-issue= article-no= start-page= 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=Comparative Analysis of a Dual DNA–RNA Panel and a DNA-Only Panel for Sarcoma: Real-World 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= 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.

Methods: This retrospective study reviewed medical records of 447 patients with mRCC treated with ICI at multiple Japanese institutions between January 2018 and August 2023. From this cohort, 178 patients with lymph node or distant metastases received either cytoreductive nephrectomy (CN group; n = 72) or ICI therapy without cytoreductive nephrectomy (non-CN group; n = 106) as first-line treatment.
Results: Median progression-free survival was 15.7 months, and median overall survival was 58.1 months. CN significantly improved OS, with the CN group's median OS not reached, compared to 29.6 months in the non-CN group (p = 0.01). Deferred CN also showed improved survival outcomes. Poor prognostic factors for immediate CN included International Metastatic Renal Cell Carcinoma Database Consortium poor risk, sarcomatoid differentiation, and a high neutrophil-to-lymphocyte ratio.
Conclusions: We developed a prognostic model to guide patient selection for CN, emphasizing the need for personalized treatment strategies. en-copyright= kn-copyright= en-aut-name=NukayaTakuhisa en-aut-sei=Nukaya en-aut-mei=Takuhisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakaharaKiyoshi en-aut-sei=Takahara en-aut-mei=Kiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ToyodaShingo en-aut-sei=Toyoda en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=InokiLan en-aut-sei=Inoki en-aut-mei=Lan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FukuokayaWataru en-aut-sei=Fukuokaya en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MoriKeiichiro en-aut-sei=Mori en-aut-mei=Keiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IwataTakehiro en-aut-sei=Iwata en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=BekkuKensuke en-aut-sei=Bekku en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MaenosonoRyoichi en-aut-sei=Maenosono en-aut-mei=Ryoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TsujinoTakuya en-aut-sei=Tsujino en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=HirasawaYosuke en-aut-sei=Hirasawa en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=YanagisawaTakafumi en-aut-sei=Yanagisawa en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=HashimotoTakeshi en-aut-sei=Hashimoto en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=KomuraKazumasa en-aut-sei=Komura en-aut-mei=Kazumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 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=15 ORCID= en-aut-name=FujitaKazutoshi en-aut-sei=Fujita en-aut-mei=Kazutoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= en-aut-name=OhnoYoshio en-aut-sei=Ohno en-aut-mei=Yoshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=17 ORCID= en-aut-name=ShirokiRyoichi en-aut-sei=Shiroki en-aut-mei=Ryoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=18 ORCID= affil-num=1 en-affil=Department of Urology, Fujita-Health University School of Medicine kn-affil= affil-num=2 en-affil=Department of Urology, Fujita-Health University School of Medicine kn-affil= affil-num=3 en-affil=Department of Urology, Kindai University Faculty of Medicine kn-affil= affil-num=4 en-affil=Department of Urology, Kindai University Faculty of Medicine kn-affil= affil-num=5 en-affil=Department of Urology, The Jikei University School of Medicine kn-affil= affil-num=6 en-affil=Department of Urology, The Jikei University School of Medicine kn-affil= affil-num=7 en-affil=Department of Urology, Okayama University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of Urology, Okayama University Graduate School of Medicine kn-affil= affil-num=9 en-affil=Department of Urology, Osaka Medical and Pharmaceutical University kn-affil= affil-num=10 en-affil=Department of Urology, Osaka Medical and Pharmaceutical University kn-affil= affil-num=11 en-affil=Department of Urology, Tokyo Medical University kn-affil= affil-num=12 en-affil=Department of Urology, The Jikei University School of Medicine kn-affil= affil-num=13 en-affil=Department of Urology, Tokyo Medical University kn-affil= affil-num=14 en-affil=Department of Urology, Osaka Medical and Pharmaceutical University kn-affil= affil-num=15 en-affil=Department of Urology, Okayama University Graduate School of Medicine kn-affil= affil-num=16 en-affil=Department of Urology, Kindai University Faculty of Medicine kn-affil= affil-num=17 en-affil=Department of Urology, Tokyo Medical University kn-affil= affil-num=18 en-affil=Department of Urology, Fujita-Health University School of Medicine kn-affil= en-keyword=cytoreductive nephrectomy kn-keyword=cytoreductive nephrectomy en-keyword=IMDC classification kn-keyword=IMDC classification en-keyword=immune checkpoint inhibitor kn-keyword=immune checkpoint inhibitor en-keyword=neutrophil-to- lymphocyte ratio kn-keyword=neutrophil-to- lymphocyte ratio en-keyword=sarcomatoid differentiation kn-keyword=sarcomatoid differentiation END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=7 article-no= start-page=e88699 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250724 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Prevalence of Locomotive Syndrome in Perioperative Patients With Localized Cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction
Many patients with cancer experience reduced activities of daily living due to muscle weakness and fatigue caused by underlying symptoms and treatment side effects. However, the incidence of locomotive syndrome, which may reduce mobility due to motor dysfunction in patients with cancer, has not been sufficiently explored. Therefore, we aimed to investigate the incidence of locomotive syndrome and identify its risk factors in perioperative patients with cancer.

Methods
We included 636 perioperative patients with localized cancer who were treated between 2020 and 2023. The severity of locomotive syndrome was classified into stages 1, 2, and 3.

Results
The overall locomotive syndrome rate was 88.1%, with distribution across stages: stage 1 (56.8%), stage 2 (17.5%), and stage 3 (13.8%). Among men, the overall incidence was 86.5%, with stage 1 (60.3%), stage 2 (15.5%), and stage 3 (10.7%). Among women, the overall incidence was 90.6%, with stage 1 (50.6%), stage 2 (20.9%), and stage 3 (19.1%). Half of patients in their 20s and two-thirds in their 30s had locomotive syndrome. The rates were 58.6%, 80.4%, 81.8%, 93.2%, and 97.8% in the 40s, 50s, 60s, 70s, and 80s age groups, respectively. Individuals in their 40s had significantly lower rates than those in older groups. Age, grip strength, and percent vital capacity were identified as risk factors.

Conclusion
A high prevalence of locomotive syndrome was observed among patients with localized cancer. Age, reduced grip strength, and lower respiratory capacity were identified as associated factors. While the findings suggest possible implications for postoperative recovery, further validation through longitudinal studies is required. en-copyright= kn-copyright= en-aut-name=KatayamaYoshimi en-aut-sei=Katayama en-aut-mei=Yoshimi 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=ItanoTakuto en-aut-sei=Itano en-aut-mei=Takuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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=5 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Rehabilitation Medicine, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=4 en-affil=Division of Physical Therapy, Kochi Professional University of Rehabilitation kn-affil= affil-num=5 en-affil=Department of Rehabilitation Medicine, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= en-keyword=aging kn-keyword=aging en-keyword=cancer kn-keyword=cancer en-keyword=locomotive syndrom kn-keyword=locomotive syndrom en-keyword=muscle strength kn-keyword=muscle strength en-keyword=perioperative system kn-keyword=perioperative system en-keyword=physical function kn-keyword=physical function en-keyword=risk factors kn-keyword=risk factors END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=20 article-no= start-page=3287 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251010 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Impact of Neoadjuvant Chemotherapy with Gemcitabine Plus S-1 in Patients with Resectable Pancreatic Ductal Adenocarcinoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: Although neoadjuvant chemotherapy (NAC) is not universally recommended for resectable pancreatic ductal adenocarcinoma (PDAC), NAC with gemcitabine plus S-1 (NAC-GS) has become a commonly used regimen for resectable PDAC in Japan. Furthermore, the impact of achieving textbook outcomes (TO) in patients receiving NAC-GS remains unclear. Methods: This retrospective study included 265 patients who were diagnosed with resectable PDAC at our institution between January 2009 and December 2023. Patients were categorized into two groups: the NAC-GS group (n = 81; 2019–2023) and the upfront surgery (UFS) group (n = 164; 2009–2018). After comparing the clinical outcomes between groups, multivariate analyses for survival were performed. Additionally, outcomes stratified by the achievement of the modified TO were analyzed in the NAC-GS group. Results: The completion rate of NAC-GS was 90.1%. Patients in the NAC-GS group exhibited significantly longer survival than those in the UFS group (2-year recurrence-free survival: 61.4% vs. 37.9%, p < 0.01; 2-year overall survival: 83.2% vs. 61.2%, p < 0.01). Multivariate analyses identified lymph node metastasis, NAC-GS induction, and completion of adjuvant chemotherapy as factors significantly associated with improved survival. Moreover, among patients who received NAC-GS, those who achieved modified TO demonstrated significantly longer survival than those who did not. Conclusions: This study demonstrated the clinical efficacy of NAC-GS in patients with resectable PDAC. Induction of NAC-GS was significantly associated with improved long-term outcomes. In multidisciplinary treatment strategies for PDAC, achieving a modified TO may lead to improved survival of patients undergoing NAC-GS. en-copyright= kn-copyright= en-aut-name=YasuiKazuya en-aut-sei=Yasui en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakagiKosei en-aut-sei=Takagi en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiTomokazu en-aut-sei=Fuji en-aut-mei=Tomokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishiyamaTakeyoshi en-aut-sei=Nishiyama en-aut-mei=Takeyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NagaiYasuo en-aut-sei=Nagai en-aut-mei=Yasuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 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=7 ORCID= en-aut-name=FujiiYuki en-aut-sei=Fujii en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki 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, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, kn-affil= affil-num=8 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=neoadjuvant chemotherapy kn-keyword=neoadjuvant chemotherapy en-keyword=pancreatic cancer kn-keyword=pancreatic cancer en-keyword=resectable kn-keyword=resectable en-keyword=textbook outcome kn-keyword=textbook outcome END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=1 article-no= start-page=468 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=The safety and efficacy of finasteride for transgender men with androgenetic alopecia: a case series en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Testosterone replacement therapy is commonly used in transgender men for masculinization. One of the most common adverse effects of testosterone replacement therapy is androgenetic alopecia. In Japan, finasteride is approved exclusively for cisgender men and is not indicated for transgender men. The aim of this clinical trial was to evaluate the safety and efficacy of finasteride in transgender men with androgenetic alopecia.
Case presentation This study included three transgender men (assigned female at birth, identifying as male), aged 44, 43, and 29 years. All participants were of Asian ethnicity. A clinical trial was conducted from October 2021 to December 2023. Transgender men aged 20–60 years who had not undergone hysterectomy, were undergoing testosterone replacement therapy, and who had been diagnosed with stage ≥ II androgenetic alopecia on the basis of the Norwood–Hamilton scale were recruited. The participants initiated treatment with 0.2 mg of finasteride per day for 3 months (phase 1). If no adverse events above grade 2 occurred, the dose was increased to 1.0 mg per day for an additional 3 months (phase 2). The primary endpoints were the incidence of treatment-related adverse events at 1 week, 1 month, and 3 months, as well as the rate of participants continuing treatment at 3 months. None of the patients experienced serious adverse events at 3 months, and all the patients extended their treatment to a total of 6 months. Improvements of at least one stage on the N–H scale were observed, but two participants experienced resumption of menstruation.
Conclusion Finasteride appears to be a safe and effective treatment for androgenetic alopecia in transgender men undergoing testosterone replacement therapy. However, its potential for reducing some of the effects of testosterone replacement therapy warrants further investigation.

The rate of lymph node metastasis is relatively low, even when an early GCLS has invaded the submucosa. We report an early GCLS with massive submucosal invasion mimicking a submucosal tumor (SMT), diagnosed by endoscopic submucosal resection (ESD) and treated with local resection and sentinel node navigation surgery (SNNS). The patient was a 40-year-old Japanese man. A protruding lesion on the greater curvature of the middle part of his stomach was detected by X-ray, and an endoscopic examination revealed a 2.5-cm protruding tumor covered with a normal mucosa and small ulcers at the apex. ESD was performed for a diagnosis. The pathological diagnosis was lymphoepithelioma-like gastric cancer (GCLS), pT1b(SM2), Ly0, V0, pHM1, pVM1. EBV infection in the cancer cells was confirmed pathologically by EBV-encoded RNA. The local resection was performed using SNNS. The patient has had no recurrence or post-gastrectomy syndrome 4 years postsurgery. EBV-associated early GCLS resembling an SMT is relatively rare, and clinicians need to be aware of this disease. Local resection using SNNS may be a surgical option for GCLS cases with a low rate of lymphatic metastasis. en-copyright= kn-copyright= en-aut-name=IsozakiHiroshi en-aut-sei=Isozaki en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumotoSasau en-aut-sei=Matsumoto en-aut-mei=Sasau kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakamaTakehiro en-aut-sei=Takama en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IsozakiYuka en-aut-sei=Isozaki en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MurakamiShigeki en-aut-sei=Murakami en-aut-mei=Shigeki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Surgery, Oomoto Hospital kn-affil= affil-num=2 en-affil=Department of Surgery, Oomoto Hospital kn-affil= affil-num=3 en-affil=Department of Surgery, Oomoto Hospital kn-affil= affil-num=4 en-affil=Department of Surgery, Oomoto Hospital kn-affil= affil-num=5 en-affil=Department of Surgery, Oomoto Hospital kn-affil= en-keyword=gastric cancer kn-keyword=gastric cancer en-keyword=gastric cancer with lymphoid stroma kn-keyword=gastric cancer with lymphoid stroma en-keyword=lymphoepithelioma-like carcinoma kn-keyword=lymphoepithelioma-like carcinoma en-keyword=Epstein Barr virus kn-keyword=Epstein Barr virus en-keyword=sentinel node navigation surgery kn-keyword=sentinel node navigation surgery END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=5 article-no= start-page=393 end-page=398 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=Gastroduodenal Artery-Preserving Pancreatoduodenectomy after Esophagectomy with Gastric Conduit Reconstruction en-subtitle= kn-subtitle= en-abstract= kn-abstract=Pancreatoduodenectomy (PD) after esophagectomy with gastric conduit reconstruction is technically challenging. Preserving the blood supply of the gastric conduit is crucial in performing PD after esophagectomy. We report the case of a 66-year-old man who underwent gastroduodenal artery-preserving PD after esophagectomy with gastric conduit reconstruction for intraductal papillary mucinous neoplasm. The patient developed pseudoaneurysm rupture postoperatively, but was successfully treated with interventional radiology. Precise assessment is important in developing a surgical strategy depending on the patient’s specific anatomy and tumor characteristics. Moreover, special attention should be paid to avoid accidental injuries of the gastric conduit and gastric vessels during surgery. en-copyright= kn-copyright= en-aut-name=MasunagaAkari en-aut-sei=Masunaga en-aut-mei=Akari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakagiKosei en-aut-sei=Takagi en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NagaiYasuo en-aut-sei=Nagai en-aut-mei=Yasuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YasuiKazuya en-aut-sei=Yasui en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujiTomokazu en-aut-sei=Fuji en-aut-mei=Tomokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamadaMotohiko en-aut-sei=Yamada en-aut-mei=Motohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NishiyamaTakeyoshi en-aut-sei=Nishiyama en-aut-mei=Takeyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KanehiraNoriyuki en-aut-sei=Kanehira en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SotaYumi en-aut-sei=Sota en-aut-mei=Yumi 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, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=pancreatoduodenectomy kn-keyword=pancreatoduodenectomy en-keyword=esophagectomy kn-keyword=esophagectomy en-keyword=gastric conduit kn-keyword=gastric conduit en-keyword=fluorescence imaging kn-keyword=fluorescence imaging END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=5 article-no= start-page=387 end-page=392 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=The Utility of a Preoperative 3D Imaging Analysis System for Trigonal Meningioma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Trigonal meningiomas are rare and pose surgical challenges due to their deep location and proximity to critical neuroanatomical structures. We present the case of a 67-year-old woman with a growing trigonal meningioma successfully resected with guidance by a preoperative 3D imaging analysis system. Integration of CT and MRI including diffusion tensor imaging (DTI) enabled precise mapping of the optic radiation, guiding a middle temporal gyrus approach. Preoperative embolization reduced tumor vascularity, facilitating gross total resection with minimal blood loss. This case highlights the effectiveness of preoperative 3D imaging systems in optimizing surgical planning and improving outcomes in complex neurosurgical cases. en-copyright= kn-copyright= en-aut-name=MoriYusuke en-aut-sei=Mori en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OtaniYoshihiro en-aut-sei=Otani en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OmaeRyo en-aut-sei=Omae en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HiranoShuichiro en-aut-sei=Hirano en-aut-mei=Shuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IshidaJoji en-aut-sei=Ishida en-aut-mei=Joji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujiiKentaro en-aut-sei=Fujii en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HarumaJun en-aut-sei=Haruma en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HiramatsuMasafumi en-aut-sei=Hiramatsu en-aut-mei=Masafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MatsushitaToshi en-aut-sei=Matsushita en-aut-mei=Toshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 ORCID= en-aut-name=SugiuKenji en-aut-sei=Sugiu en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 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=12 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=Division of Radiological Technology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Radiology, Medical Development Field, Okayama University 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= en-keyword=trigonal meningioma kn-keyword=trigonal meningioma en-keyword=imaging analysis kn-keyword=imaging analysis en-keyword=diffusion tensor imaging kn-keyword=diffusion tensor imaging END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=5 article-no= start-page=369 end-page=379 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=Blood Pressure and Heart Rate Patterns Identified by Unsupervised Machine Learning and Their Associations with Subclinical Cerebral and Renal Damage in a Japanese Community: The Masuda Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=We applied unsupervised machine learning to analyze blood pressure (BP) and resting heart rate (HR) patterns measured during a 1-year period to assess their cross-sectional relationships with subclinical cerebral and renal target damage. Dimension reduction via uniform manifold approximation and projection, followed by K-means++ clustering, was used to categorize 362 community-dwelling participants (mean age, 56.2 years; 54.9% women) into three groups: Low BP and Low HR (Lo-BP/Lo-HR), High BP and High HR (Hi-BP/Hi-HR), and Low BP and High HR (Lo-BP/Hi-HR). Cerebral vessel lesions were defined as the presence of at least one of the following magnetic resonance imaging findings: lacunar infarcts, white matter hyperintensities, cerebral microbleeds, or intracranial artery stenosis. A high urinary albumin-to-creatinine ratio (UACR) was defined as the top 10% (≥ 12 mg/g) of the mean value from ≥2 measurements. Poisson regression with robust error variance, adjusted for demographics, lifestyle, and medical history, showed that the Hi-BP/Hi-HR group had relative risks of 3.62 (95% confidence interval, 1.75-7.46) for cerebral vessel lesions and 3.58 (1.33-9.67) for high UACR, and the Lo-BP/Hi-HR group had a relative risk of 3.09 (1.12-8.57) for high UACR, compared with the Lo-BP/Lo-HR group. These findings demonstrate the utility of an unsupervised, data-driven approach for identifying physiological patterns associated with subclinical target organ damage. en-copyright= kn-copyright= en-aut-name=HisamatsuTakashi en-aut-sei=Hisamatsu en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KinutaMinako en-aut-sei=Kinuta en-aut-mei=Minako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MunetomoSosuke en-aut-sei=Munetomo en-aut-mei=Sosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FukudaMari en-aut-sei=Fukuda en-aut-mei=Mari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KojimaKatsuhide en-aut-sei=Kojima en-aut-mei=Katsuhide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TaniguchiKaori en-aut-sei=Taniguchi en-aut-mei=Kaori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakahataNoriko en-aut-sei=Nakahata en-aut-mei=Noriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KandaHideyuki en-aut-sei=Kanda en-aut-mei=Hideyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Environmental Medicine and Public Health, Izumo, Shimane University Faculty of Medicine kn-affil= affil-num=7 en-affil=Department of Health and Nutrition, The University of Shimane Faculty of Nursing and Nutrition kn-affil= affil-num=8 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=blood pressure kn-keyword=blood pressure en-keyword=heart rate kn-keyword=heart rate en-keyword=subclinical disease kn-keyword=subclinical disease en-keyword=uniform manifold approximation and projection kn-keyword=uniform manifold approximation and projection en-keyword=unsupervised machine learning kn-keyword=unsupervised machine learning END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=5 article-no= start-page=353 end-page=358 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=Comparison of Extraocular Muscles in Patients with Exotropia and Healthy Participants Using Anterior Segment Optical Coherence Tomography en-subtitle= kn-subtitle= en-abstract= kn-abstract=To analyze and characterize the medial and lateral rectus muscles in patients with exotropia using anterior segment optical coherence tomography (AS-OCT). This study included 24 patients with exotropia (48 eyes) and 25 healthy individuals (50 eyes). Anterior segment optical coherence tomography was used to construct the en face images. The anterior chamber angle to the extraocular muscle insertion distance, muscle width, and muscle fiber angle from the muscle insertion sites were compared between the exotropia and the control groups. The correlation between these parameters and age or angle of deviation was evaluated. The mean ages were 13.2±4.1 years for the exotropia group and 17.6±7.2 years for the control group. The lateral rectus angle was significantly more inwardly rotated in the exotropia group than in the control group (1.6±6.3°, −1.4±4.0°, p=0.014). With increasing angle of deviation, the width of the lateral rectus increased (p=0.002). Our results indicate that the lateral rectus angle is significantly more inwardly rotated in patients with exotropia. These findings should contribute to a deeper understanding of the extraocular muscles in patients with this condition. en-copyright= kn-copyright= en-aut-name=ChiharaYuki en-aut-sei=Chihara en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HamasakiIchiro en-aut-sei=Hamasaki en-aut-mei=Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShibataKiyo en-aut-sei=Shibata en-aut-mei=Kiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MorisawaShin en-aut-sei=Morisawa en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KonoReika en-aut-sei=Kono en-aut-mei=Reika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KanenagaKeisuke en-aut-sei=Kanenaga en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MorizaneYuki en-aut-sei=Morizane en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=exotropia kn-keyword=exotropia en-keyword=AS-OCT kn-keyword=AS-OCT en-keyword=anterior chamber angle to extraocular muscle insertion distance kn-keyword=anterior chamber angle to extraocular muscle insertion distance en-keyword=muscle width kn-keyword=muscle width en-keyword=muscle fiber angle kn-keyword=muscle fiber angle END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=5 article-no= start-page=345 end-page=352 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=Inhibition of Air-Exposure Stress–Induced Autolysis in Clostridium perfringens by Zn2+ en-subtitle= kn-subtitle= en-abstract= kn-abstract=Clostridium perfringens is a pathogenic anaerobe that causes gas gangrene and food poisoning. Although autolysin-mediated reorganization of the bacterial cell wall is crucial for cell division, excessive autolysin activity induced by stressors can lead to cell lysis. In C. perfringens, air exposure is a significant stressor that causes cell lysis, and Acp (N-acetylglucosaminidase) is known to be a major autolysin. To further facilitate C. perfringens research, a technology to prevent air-induced cell lysis must be developed. This study investigated the role of Acp in air-induced autolysis and explored potential inhibitors that would prevent cell lysis during experimental procedures. Morphological analyses confirmed that Acp functions as an autolysin in C. perfringens, as acpdeficient strains exhibited filamentous growth. The mutants exhibited negligible autolysis under air-exposure stress, confirming the involvement of Acp in the autolytic process. We also evaluated the effects of various divalent cations on Acp activity in vitro and identified Zn2+ as a potent inhibitor. Brief treatment with a Zn2+- containing buffer induced dose-dependent cell elongation and autolysis inhibition in C. perfringens. These findings demonstrate that simple Zn2+ treatment before experiments stabilizes C. perfringens cells, reducing autolysis under aerobic conditions and facilitating various biological studies, except morphological analyses. en-copyright= kn-copyright= en-aut-name=MatsunagaNozomu en-aut-sei=Matsunaga en-aut-mei=Nozomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=EgusaSeira en-aut-sei=Egusa en-aut-mei=Seira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AonoRiyo en-aut-sei=Aono en-aut-mei=Riyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TamaiEiji en-aut-sei=Tamai en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HitusmotoYasuo en-aut-sei=Hitusmoto en-aut-mei=Yasuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KatayamaSeiichi en-aut-sei=Katayama en-aut-mei=Seiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Life Science, Faculty of Science, Okayama University of Science kn-affil= affil-num=2 en-affil=Department of Life Science, Faculty of Science, Okayama University of Science kn-affil= affil-num=3 en-affil=Department of Medical Technology, Kagawa Prefectural University of Health Sciences kn-affil= affil-num=4 en-affil=Department of Infectious Disease, College of Pharmaceutical Science, Matsuyama University kn-affil= affil-num=5 en-affil=Department of Life Science, Faculty of Science, Okayama University of Science kn-affil= affil-num=6 en-affil=Department of Life Science, Faculty of Science, Okayama University of Science kn-affil= en-keyword=Clostridium perfringens kn-keyword=Clostridium perfringens en-keyword=autolysin kn-keyword=autolysin en-keyword=zinc kn-keyword=zinc en-keyword=air-exposure autolysis kn-keyword=air-exposure autolysis END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=5 article-no= start-page=339 end-page=343 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=Evaluation of Scleral Adjustment Method: A Novel Adjustable Suture Technique in Strabismus Surgery en-subtitle= kn-subtitle= en-abstract= kn-abstract=To determine whether passing a pole suture through the sclera at two points provides fixation comparable to that of a sliding noose, we measured the tensile strength of the suture‒sclera interface during simulated traction. In this in vitro study, three suture patterns were evaluated in porcine eyeballs, using 6-0 polyglycolic acid sutures. Patterns A (control), B (second suture pass perpendicular), and C (second suture pass in the same direction) were compared. The tensile strength of each pattern was measured 20 times using a KANON TK300CN, and the results were analyzed using the Kruskal‒Wallis test. Pattern A showed a tensile strength of 2±4 gram-force (gf) (range: 0-12). Pattern B showed 112±38 gf (range: 61-184). Pattern C showed 139±31 gf (range: 97-204). Patterns B and C had significantly higher tensile strengths than Pattern A (p<0.001). Although Pattern C was not significantly different from Pattern B (p=0.363), it exhibited the highest tensile strength. Lifting the suture between the first and second suture passes allows for an adjustable suture length, suggesting that adjustability can be achieved using only the sclera. This scleral adjustment method with a second suture pass offers a durable means of securing extraocular muscles and may represent a valuable addition to adjustable suturing techniques. en-copyright= kn-copyright= en-aut-name=HamasakiIchiro en-aut-sei=Hamasaki en-aut-mei=Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShibataKiyo en-aut-sei=Shibata en-aut-mei=Kiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Lino Eye Clinic kn-affil= affil-num=2 en-affil=Lino Eye Clinic kn-affil= en-keyword=scleral adjustment method kn-keyword=scleral adjustment method en-keyword=adjustable suture technique kn-keyword=adjustable suture technique en-keyword=hang-loose method kn-keyword=hang-loose method en-keyword=tensile strength kn-keyword=tensile strength en-keyword=polyglycolic acid sutures kn-keyword=polyglycolic acid sutures END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=5 article-no= start-page=329 end-page=337 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=Current Status of Extracorporeal Membrane Oxygenation as a Treatment Strategy for Primary Graft Dysfunction after Lung Transplantation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Primary graft dysfunction (PGD) is one of the major risk factors affecting patients’ short- and long-term survival after lung transplantation. No particular management strategy has been established for PGD; supportive care is the mainstay of PGD treatment. When a supportive strategy fails, the patient may require the introduction of extracorporeal membrane oxygenation (ECMO) as the last-resort measure for severe PGD. A variety of study of ECMO as a PGD treatment was reported and the management of PGD patients developed so far. Early recognition of a patient’s need for ECMO and its prompt initiation are critical to improved outcomes. The use of venovenous-ECMO became the preferred procedure for PGD rather than venoarterial-ECMO. However, the current ECMO strategy has limitations, and using ECMO to manage patients with PGD is not sufficiently effective. Further studies are required to develop this promising technology. en-copyright= kn-copyright= en-aut-name=MatsubaraKei en-aut-sei=Matsubara en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyoshiKentaroh en-aut-sei=Miyoshi en-aut-mei=Kentaroh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= affil-num=1 en-affil=Department of Thoracic Surgery, Hiroshima City Hiroshima Citizens Hospital kn-affil= affil-num=2 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=lung transplantation kn-keyword=lung transplantation en-keyword=primary graft dysfunction kn-keyword=primary graft dysfunction en-keyword=extracorporeal membrane oxygenation kn-keyword=extracorporeal membrane oxygenation en-keyword=ex vivo lung perfusion kn-keyword=ex vivo lung perfusion END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=5 article-no= start-page=321 end-page=328 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=A Review of the Endoscopic Treatment for Bile Leak Following Cholecystectomy and Hepatic Surgery en-subtitle= kn-subtitle= en-abstract= kn-abstract=Bile leak occurs in 2-25% of liver transplant, 3-27% of hepatic resection, and 0.1-4% of cholecystectomy cases. The clinical course of bile leak varies depending on the type of surgery that caused the fistula, as well as the type, severity, and timing of bile duct injury. Although infections resulting from bile leak can be life-threatening, the introduction of endoscopic treatment has enabled some patients to avoid reoperation and has reduced the negative impact on quality of life associated with external fistulas for percutaneous drainage. Endoscopic interventions, such as sphincterotomy and stent placement, reduce the pressure gradient between the bile duct and duodenum, facilitating bile drainage through the papilla and promoting the closure of the leak. We reviewed the literature from 2004 to 2024 regarding bile leak following cholecystectomy and liver surgery, examining recommended techniques, timing, and treatment outcomes. In cases of bile leak following cholecystectomy, clinical success was achieved in 72-96% of cases, while success rates for bile leak following liver surgery ranged from 50% to 100%. Although endoscopic treatment is effective, it is not universally applicable, and its limitations must be carefully considered. en-copyright= kn-copyright= en-aut-name=ObataTaisuke en-aut-sei=Obata en-aut-mei=Taisuke 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=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University 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 Gastroenterology and Hepatology, Okayama University Hospital kn-affil= en-keyword=bile leak kn-keyword=bile leak en-keyword=cholecystectomy kn-keyword=cholecystectomy en-keyword=hepatic surgery kn-keyword=hepatic surgery en-keyword=endoscopic retrograde cholangiography kn-keyword=endoscopic retrograde cholangiography en-keyword=bridging stent placement kn-keyword=bridging stent placement END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=9 article-no= start-page=4815 end-page=4837 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=Spatiotemporal evolution of ecosystem carbon storage under land use/land cover dynamics in the coastal region of Central Vietnam en-subtitle= kn-subtitle= en-abstract= kn-abstract=Ecosystem carbon storage is a cost-effective strategy for global climate change mitigation, and its fluctuation is markedly shaped by land use/land cover (LULC) dynamics. Taking Danang city as an example of Central Coastal Vietnam, this study aims to assess LULC changes and analyze the spatiotemporal evolution of carbon storage from 2023 to 2050 under four LULC change scenarios, including natural trend scenario (NTS), ecological protection scenario (EPS), economic development scenario (EDS), and cropland protection scenario (CPS), by integrating the support vector machine-cellular automata-Markov (SVM-CA-Markov) model and the InVEST model. The Optimal Parameters-based Geographical Detector (OPGD) model was subsequently employed to elucidate the impacts of driving factors on the spatial distribution of carbon storage. The results showed that, from 2007 to 2023, Danang city experienced a dramatic back-and-forth transformation between LULC types, with the predominant transitions being from natural forest to acacia tree-dominated plantation forest (6492.31 ha), and from cropland to settlements, acacia tree-dominated plantation forest, and other land (5483.05 ha, 3763.66 ha, 2762.35 ha, respectively). Between 2023 and 2050, LULC transformations in Danang city are projected to yield varying degrees of carbon storage levels across different scenarios. Specifically, carbon storage is anticipated to dwindle by 0.221 Mt, 0.223 Mt, and 0.298 Mt under NTS, EDS, and CPS, respectively, while enhancing by 0.141 Mt under EPS. Regarding the spatial distribution of carbon storage, high values will be chiefly found in the western high-elevation mountainous region, while low values will be concentrated mostly in the eastern lower-lying areas of the city. Additionally, elevation and temperature acted as the two most significant driving factors influencing the spatial distribution of carbon storage, with Q values of 0.88 and 0.86 (p-value < 0.05), respectively. For interaction detection, the combination of elevation and soil exhibited a synergistic reinforcement effect on the spatial partitioning of carbon storage, with a high Q value of 0.9566 (p-value < 0.05). Our study highlights the necessity of ecological conservation measures in Danang city in the on-track pursuit of national net-zero carbon emissions by 2050. en-copyright= kn-copyright= en-aut-name=HoViet Hoang en-aut-sei=Ho en-aut-mei=Viet Hoang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MoritaHidenori en-aut-sei=Morita en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HoThanh Ha en-aut-sei=Ho en-aut-mei=Thanh Ha kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=BachoferFelix en-aut-sei=Bachofer en-aut-mei=Felix 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=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=University of Agriculture and Forestry, Hue University kn-affil= affil-num=4 en-affil=German Aerospace Center (DLR), Earth Observation Center kn-affil= en-keyword=Carbon sequestration kn-keyword=Carbon sequestration en-keyword=Scenario-based modeling kn-keyword=Scenario-based modeling en-keyword=Remote sensing kn-keyword=Remote sensing en-keyword=Spatial autocorrelation analysis kn-keyword=Spatial autocorrelation analysis END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=1 article-no= start-page=56 end-page=22 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250911 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The Ethnic Integration and Security Issues in Estonia : In light of the results of the “Social Awareness Survey”(May 2023) kn-title=エストニアの民族間統合と安全保障問題 ― 「社会意識調査」(2023年5月)の結果に照らして― en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=KawaharaY. en-aut-sei=Kawahara en-aut-mei=Y. kn-aut-name=河原祐馬 kn-aut-sei=河原 kn-aut-mei=祐馬 aut-affil-num=1 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 END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=1 article-no= start-page=e70149 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=Clinical Impacts of Minimally Invasive Transperineal Abdominoperineal Resection in Crohn's Disease: A Retrospective Analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Crohn's disease (CD) often leads to complex anorectal complications, posing significant challenges in surgical management. Transperineal abdominoperineal resection (TpAPR) has emerged as a minimally invasive alternative to APR. This study aims to evaluate the safety and efficacy of TpAPR compared to APR in patients with CD.
Methods: A retrospective analysis was conducted on 19 CD patients who underwent either minimally invasive TpAPR (n = 11) or APR (n = 8) between 2008 and 2023 from a single institution. The primary outcomes were assessed: intraoperative blood loss, operative time, and surgical site infection (SSI) rates.
Results: The minimally invasive TpAPR group exhibited significantly reduced intraoperative blood loss (223 mL vs. 533 mL, p = 0.04) and a lower incidence of SSI rates (36.4% vs. 75%, p = 0.07). Operative time and hospital stay were comparable between groups.
Conclusion: Minimally invasive TpAPR demonstrates potential benefits over APR in reducing blood loss and SSI rates in CD patients. Further large-scale studies are warranted to confirm these findings. en-copyright= kn-copyright= en-aut-name=KondoYoshitaka en-aut-sei=Kondo en-aut-mei=Yoshitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=ShojiRyohei en-aut-sei=Shoji en-aut-mei=Ryohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=HiraokaSakiko en-aut-sei=Hiraoka en-aut-mei=Sakiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshidaYusuke en-aut-sei=Yoshida en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsumiYuki en-aut-sei=Matsumi en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= en-aut-name=TeraishiFuminori en-aut-sei=Teraishi en-aut-mei=Fuminori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 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=11 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Research Center for Intestinal Health Science, Okayama University kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Crohn's disease kn-keyword=Crohn's disease en-keyword=intraoperative blood loss kn-keyword=intraoperative blood loss en-keyword=minimally invasive surgery kn-keyword=minimally invasive surgery en-keyword=surgical site infection (SSI) kn-keyword=surgical site infection (SSI) en-keyword=transperineal abdominoperineal resection (TpAPR) kn-keyword=transperineal abdominoperineal resection (TpAPR) END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=4 article-no= start-page=401 end-page=409 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250801 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=High-Definition Topographic Archiving and Educational Applications in Regions Affected by the 2024 Noto Peninsula Earthquake en-subtitle= kn-subtitle= en-abstract= kn-abstract=The 2024 Noto Peninsula earthquake (Mw 7.5) caused extensive damage in Ishikawa Prefecture, Japan, and surrounding areas, with considerable coastal uplift and tsunami flooding. Past 100 years’ records show no earthquake above Mw 7.0 in the Noto Peninsula, so for everyone alive today, this event is truly without precedent. Therefore, we aimed to support disaster prevention education by developing teaching materials using unmanned aerial vehicles (UAVs) based on digitally archived topographic changes. High-definition topographic data collected from multiple UAV surveys were processed into digital and analog formats, including 3D models, spherical panorama images, and 3D printings. These materials were designed to provide detailed and intuitive representations of post-disaster landforms and were used as educational tools in schools. The learning materials were introduced during a workshop for disaster-affected teachers, featuring hands-on activities to help participants familiarize themselves with the materials, and explore their integration into geography and science classes. Feedback from participants indicated that these tools were highly effective in enhancing classroom learning. The results of this study are expected to contribute to preserving disaster records while enhancing disaster awareness in educational settings and local communities. en-copyright= kn-copyright= en-aut-name=OguraTakuro en-aut-sei=Ogura en-aut-mei=Takuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamauchiHiroyuki en-aut-sei=Yamauchi en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AokiTatsuto en-aut-sei=Aoki en-aut-mei=Tatsuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MattaNobuhisa en-aut-sei=Matta en-aut-mei=Nobuhisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IizukaKotaro en-aut-sei=Iizuka en-aut-mei=Kotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IwasaYoshiya en-aut-sei=Iwasa en-aut-mei=Yoshiya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakahashiTakayuki en-aut-sei=Takahashi en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HayashiKiyomi en-aut-sei=Hayashi en-aut-mei=Kiyomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HattanjiTsuyoshi en-aut-sei=Hattanji en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OguchiTakashi en-aut-sei=Oguchi en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Graduate School of Education, Hyogo University of Teacher Education kn-affil= affil-num=2 en-affil=Art Research Center, Ritsumeikan University kn-affil= affil-num=3 en-affil=Faculty of Regional Development Studies, Kanazawa University kn-affil= affil-num=4 en-affil=Graduate School of Education, Okayama University kn-affil= affil-num=5 en-affil=Center for Spatial Information Science, The University of Tokyo kn-affil= affil-num=6 en-affil=Faculty of Education, University of Teacher Education Fukuoka kn-affil= affil-num=7 en-affil=International Research Institute of Disaster Science, Tohoku University kn-affil= affil-num=8 en-affil=Faculty of Regional Development Studies, Kanazawa University kn-affil= affil-num=9 en-affil=Institute of Life and Environmental Sciences, University of Tsukuba kn-affil= affil-num=10 en-affil=Center for Spatial Information Science, The University of Tokyo kn-affil= en-keyword=disaster risk-reduction education kn-keyword=disaster risk-reduction education en-keyword=uplift area kn-keyword=uplift area en-keyword=UAV kn-keyword=UAV en-keyword=3D printing kn-keyword=3D printing END start-ver=1.4 cd-journal=joma no-vol=30 cd-vols= no-issue=1 article-no= start-page=144 end-page=156 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241109 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Lymphadenectomy and chemotherapy are effective treatments for patients with 2023 international federation of gynecology and obstetrics stage IIC-high risk endometrial cancer in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background In early-stage endometrial cancer (EC), the treatment of aggressive histological subtypes (endometrioid carcinoma grade 3, serous carcinoma, clear-cell carcinoma, undifferentiated carcinoma, mixed carcinoma, and carcinosarcoma) is controversial. We aimed to investigate the treatment of patients with International Federation of Gynecology and Obstetrics (FIGO) stage IC and stage IIC EC according to the 2023 classification.
Methods We retrospectively identified patients with FIGO 2023 stage IC, IIC-intermediate risk (IIC-I), and IIC-high risk (IIC-H) EC who underwent adjuvant therapy or observation after surgery at eight medical institutions from 2004 to 2023. Progression-free survival (PFS) and overall survival (OS) were evaluated using Kaplan–Meier estimates and univariate and multivariate analyses.
Results The PFS and OS were significantly worse in patients with FIGO 2023 stage IIC-H EC than in those with FIGO 2023 stage IIC-I EC (PFS: p = 0.008 and OS: p = 0.006). According to the FIGO 2023 stage IIC-H classification, lymphadenectomy and chemotherapy resulted in better prognoses regarding both PFS and OS (p < 0.001 for both) than other treatments. Our findings suggest that lymphadenectomy and chemotherapy effectively reduced vaginal stump and lymph node metastases in FIGO 2023 stage IIC-H EC (p < 0.001 and p = 0.008, respectively). Furthermore, in the multivariate analysis, not undergoing lymphadenectomy or chemotherapy were independent predictors of recurrence and poor prognoses in patients with FIGO 2023 stage IIC-H EC (p < 0.001 and p = 0.031, respectively).
Conclusion Lymphadenectomy and chemotherapy resulted in better prognoses regarding both recurrence and survival in patients with FIGO 2023 stage IIC high-risk EC. en-copyright= kn-copyright= en-aut-name=TaniYoshinori en-aut-sei=Tani en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakamuraKeiichiro en-aut-sei=Nakamura en-aut-mei=Keiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YorimitsuMasae en-aut-sei=Yorimitsu en-aut-mei=Masae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SekiNoriko en-aut-sei=Seki en-aut-mei=Noriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakanishiMie en-aut-sei=Nakanishi en-aut-mei=Mie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ItouHironori en-aut-sei=Itou en-aut-mei=Hironori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ShimizuMiyuki en-aut-sei=Shimizu en-aut-mei=Miyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamamotoDan en-aut-sei=Yamamoto en-aut-mei=Dan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TakaharaEtsuko en-aut-sei=Takahara en-aut-mei=Etsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MasuyamaHisashi en-aut-sei=Masuyama en-aut-mei=Hisashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Obstetrics and Gynecology, Hiroshima City Hiroshima Citizens Hospital kn-affil= affil-num=4 en-affil=Department of Obstetrics and Gynecology, Japanese Red Cross Society Himeji Hospital kn-affil= affil-num=5 en-affil=Department of Obstetrics and Gynecology, Kagawa Prefectural Central Hospital kn-affil= affil-num=6 en-affil=Department of Obstetrics and Gynecology, National Hospital Organization Iwakuni Clinical Center kn-affil= affil-num=7 en-affil=Department of Obstetrics and Gynecology, Kagawa Rosai Hospital kn-affil= affil-num=8 en-affil=Department of Obstetrics and Gynecology, National Organization Fukuyama Medical Center kn-affil= affil-num=9 en-affil=Department of Obstetrics and Gynecology, Fukuyama City Hospital kn-affil= affil-num=10 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Endometrial cancer kn-keyword=Endometrial cancer en-keyword=FIGO 2023 kn-keyword=FIGO 2023 en-keyword=Stage IIC high risk kn-keyword=Stage IIC high risk en-keyword=Lymphadenectomy kn-keyword=Lymphadenectomy en-keyword=Chemotherapy kn-keyword=Chemotherapy END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250704 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Primary tumour resection plus systemic therapy versus systemic therapy alone in metastatic breast cancer (JCOG1017, PRIM-BC): a randomised clinical trial en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Several prospective studies have evaluated the benefit of primary tumour resection (PTR) in de novo Stage IV breast cancer (BC) patients, but it remains controversial. We aimed to investigate whether PTR improves the survival of de novo stage IV BC patients.
Methods: De novo stage IV BC patients were enrolled in the first registration and received systemic therapies according to clinical subtypes. Patients without progression after primary systemic therapy for 3 months were randomly assigned 1:1 to systemic therapy alone (arm A) or PTR plus systemic therapy (arm B). The primary endpoint was overall survival (OS), and the secondary endpoints included local relapse-free survival (LRFS).
Results: Five hundred seventy patients were enrolled between May 5, 2011, and May 31, 2018. Of these, 407 were randomised to arm A (N = 205) or arm B (N = 202). The median follow-up time of all randomised patients was 60 months. The difference in OS was not statistically significant (HR 0.86 90% CI 0.69–1.07, one-sided p = 0.13). Median OS was 69 months (arm A) and 75 months (arm B). In the subgroup analysis, PTR was associated with improved OS in pre-menopausal patients, or those with single-organ metastasis. LRFS in arm B was significantly longer than that in arm A (median LRFS 20 vs. 63 months: HR 0.42, 95% CI 0.33–0.53, p < 0.0001). There were no treatment-related deaths.
Conclusions: PTR did not prolong OS. However, it improved local control and might benefit a subset of patients, such as those with premenopausal status or with single-organ metastasis. It also improved local relapse-free survival (LRFS), which is a clinically meaningful outcome in trials of systemic therapy.

The Asia-Pacific body mass index (BMI) classification sets lower obesity cutoffs than the conventional BMI classification for all races, generally reflecting the lower BMIs in Asians. This longitudinal study evaluated the association between BMI, as classified by the Asia-Pacific BMI system, and CKD development in non-diabetic Asian adults. Methods: A population-based longitudinal study (1998–2023) was conducted in non-diabetic Japanese adults (hemoglobin A1c < 6.5%) in Zentsuji City (Kagawa Prefecture, Japan). The generalized gamma model was used to assess the relationship between time-varying BMI categories and CKD development, stratified by sex. CKD was defined as an estimated glomerular filtration rate of <60 mL/min/1.73 m2. BMI was calculated as weight (kg) divided by the square of height (m2) and categorized per the Asia-Pacific classification as overweight (23.0–24.9 kg/m2), obesity class I (25.0–29.9 kg/m2), and obesity class II (≥30.0 kg/m2). Results: CKD developed in 34.2% of 3098 men and 34.8% of 4391 women. The mean follow-up times were 7.41 years for men and 8.25 years for women. During follow-up, the BMI distributions for men were 5.0% underweight, 43.3% normal weight, 25.6% overweight, 24.1% obesity class I, and 2.0% obesity class II; those for women were 7.7%, 50.5%, 20.5%, 18.3%, and 2.9%, respectively. Compared with normal weight, obesity class I was associated with a 6% (95% confidence interval [CI]: 2–10%) shorter time to CKD onset in men and 5% (95% CI: 2–7%) in women. In both sexes, obesity class II showed shorter survival times than normal weight by point estimates, although all 95% CIs crossed the null value. Conclusions: Obesity, as classified by the Asia-Pacific BMI system, shortened the time to CKD onset in non-diabetic Asians. The conventional BMI cutoff for obesity (≥30.0 kg/m2) may be too high to identify CKD risk in this population. The findings of this study may be useful for public health professionals in designing interventions to prevent CKD. en-copyright= kn-copyright= en-aut-name=OkawaYukari en-aut-sei=Okawa en-aut-mei=Yukari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsudaToshihide en-aut-sei=Tsuda en-aut-mei=Toshihide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Public Health and Welfare, Zentsuji City Hall kn-affil= affil-num=2 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=body mass index kn-keyword=body mass index en-keyword=chronic kidney disease kn-keyword=chronic kidney disease en-keyword=East Asian kn-keyword=East Asian en-keyword=longitudinal studies kn-keyword=longitudinal studies en-keyword=risk factors kn-keyword=risk factors END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue=1 article-no= start-page=e261 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230703 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Alcohol consumption, multiple Lugol‐voiding lesions, and field cancerization en-subtitle= kn-subtitle= en-abstract= kn-abstract=The development of multiple squamous cell carcinomas (SCC) in the upper aerodigestive tract, which includes the oral cavity, pharynx, larynx, and esophagus, is explained by field cancerization and is associated with alcohol consumption and cigarette smoking. We reviewed the association between alcohol consumption, multiple Lugol-voiding lesions, and field cancerization, mainly based on the Japan Esophageal Cohort study. The Japan Esophageal Cohort study is a prospective cohort study that enrolled patients with esophageal SCC after endoscopic resection. Enrolled patients received surveillance by gastrointestinal endoscopy every 6 months and surveillance by an otolaryngologist every 12 months. The Japan Esophageal Cohort study showed that esophageal SCC and head and neck SCC that developed after endoscopic resection for esophageal SCC were associated with genetic polymorphisms related to alcohol metabolism. They were also associated with Lugol-voiding lesions grade in the background esophageal mucosa, the score of the health risk appraisal model for predicting the risk of esophageal SCC, macrocytosis, and score on alcohol use disorders identification test. The standardized incidence ratio of head and neck SCC in patients with esophageal SCC after endoscopic resection was extremely high compared to the general population. Drinking and smoking cessation is strongly recommended to reduce the risk of metachronous esophageal SCC after treatment of esophageal SCC. Risk factors for field cancerization provide opportunities for early diagnosis and minimally invasive treatment. Lifestyle guidance of alcohol consumption and cigarette smoking for esophageal precancerous conditions, which are endoscopically visualized as multiple Lugol-voiding lesions, may play a pivotal role in decreasing the incidence and mortality of esophageal SCC. en-copyright= kn-copyright= en-aut-name=KatadaChikatoshi en-aut-sei=Katada en-aut-mei=Chikatoshi kn-aut-name= kn-aut-sei= kn-aut-mei=

Bilateral pulmonary emphysema was confirmed. Persistent air leakage was observed, and a thoracoscopic bullectomy was performed. Although the thoracoscopic bullectomy was completed uneventfully, pre-extubation chest X-ray imaging indicated hyper-lucency occupying the right upper part of the thoracic cavity, suggesting right-sided pneumothorax. CT imaging indicated a right-upper-lobe expanded bulla. Extubation was performed, and the hyperinflated bulla gradually deflated. Careful management of bulla expansion and respiratory status may be necessary for patients with obesity and large bullae, especially in one-lung ventilation cases. en-copyright= kn-copyright= en-aut-name=MatsubaraKei en-aut-sei=Matsubara en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsubaraKei en-aut-sei=Matsubara en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HiranoYutaka en-aut-sei=Hirano en-aut-mei=Yutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujiwaraToshiya en-aut-sei=Fujiwara en-aut-mei=Toshiya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Thoracic Surgery, Hiroshima City Hiroshima Citizens Hospital kn-affil= affil-num=2 en-affil=Department of Thoracic Surgery, Hiroshima City Hiroshima Citizens Hospital kn-affil= affil-num=3 en-affil=Department of Thoracic Surgery, Hiroshima City Hiroshima Citizens Hospital kn-affil= affil-num=4 en-affil=Department of Thoracic Surgery, Hiroshima City Hiroshima Citizens Hospital kn-affil= en-keyword=giant bulla kn-keyword=giant bulla en-keyword=pneumothorax kn-keyword=pneumothorax en-keyword=obesity kn-keyword=obesity en-keyword=positive pressure ventilation kn-keyword=positive pressure ventilation en-keyword=one lung ventilation kn-keyword=one lung ventilation END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=4 article-no= start-page=305 end-page=309 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=A Rare Presentation of Pneumonic-Type Adenocarcinoma Hidden behind Empyema en-subtitle= kn-subtitle= en-abstract= kn-abstract=Pneumonic-type adenocarcinoma (P-ADC) can closely mimic pneumonia. We report a P-ADC initially diagnosed as pneumonia which developed into a pulmonary abscess and empyema. A 50-year-old Japanese male diagnosed with pneumonia, pulmonary abscess, and empyema was administered antibiotics and a chest tube for drainage, which improved his symptoms and blood test results. However, chest computed tomography showed an enlarged infiltrative shadow. The patient underwent bronchoscopy and was diagnosed with an adenocarcinoma. This case highlights the importance of considering P-ADC in differential diagnoses when a pneumonia-like shadow enlarges post-empyema treatment.

There appear to be no established guidelines for managing symptomatic PCE, and there is scarce literature on CPC embolisms. This is a first report of a case of pulmonary CPC embolism following PVP. The patient, a 63-year-old Chinese female, was administered anticoagulant treatment and achieved a satisfactory outcome. Her case highlights the severe potential morbidity associated with CPC leakage and emphasizes the efficacy of anticoagulant treatment for managing pulmonary CPC embolisms. en-copyright= kn-copyright= en-aut-name=FengRuibin en-aut-sei=Feng en-aut-mei=Ruibin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ZhuBikang en-aut-sei=Zhu en-aut-mei=Bikang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WeiDanyun en-aut-sei=Wei en-aut-mei=Danyun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ZhuDingjiao en-aut-sei=Zhu en-aut-mei=Dingjiao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ChenCairu en-aut-sei=Chen en-aut-mei=Cairu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Orthopedics, the Ninth Affiliated Hospital of Guangxi Medical University kn-affil= affil-num=2 en-affil=Department of Orthopedics, the Ninth Affiliated Hospital of Guangxi Medical University kn-affil= affil-num=3 en-affil=Department of Orthopedics, the Ninth Affiliated Hospital of Guangxi Medical University kn-affil= affil-num=4 en-affil=Department of Radiology, the Ninth Affiliated Hospital of Guangxi Medical University kn-affil= affil-num=5 en-affil=Department of Orthopedics, the Ninth Affiliated Hospital of Guangxi Medical University kn-affil= en-keyword=percutaneous vertebroplasty kn-keyword=percutaneous vertebroplasty en-keyword=thoracic vertebrae fracture kn-keyword=thoracic vertebrae fracture en-keyword=calcium phosphate cement kn-keyword=calcium phosphate cement en-keyword=pulmonary embolism kn-keyword=pulmonary embolism END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=4 article-no= start-page=293 end-page=297 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=Effectiveness of Pallidal Stimulation for Dystonic Storm and Subsequent Ssevere Posterior Reversible Encephalopathy Syndrome in a Patient with GNAO1 Variant en-subtitle= kn-subtitle= en-abstract= kn-abstract=GNAO1 variant affects primarily the brain and neurodevelopment, leading to a range of motor disorders including seizures beginning in infancy and involuntary movements such as dyskinesia and dystonia. Our patient, a 15-year-old Japanese female, began exhibiting involuntary movements at age 4. A de novo missense mutation (NM_020988.3: c.228C>G, NP_066268.1: p.(Asn76Lys)) in the GNAO1 gene was identified when the patient was 15, and during the same year she developed influenza pneumonia, accompanied by dystonic storm. She required intensive care with mechanical ventilation and underwent a tracheostomy. She also developed posterior reversible encephalopathy syndrome. Globus pallidal stimulation was administered, leading to an improvement in the dystonic storm. Early consideration of globus pallidal stimulation is recommended when treating difficult-to-manage dystonic storms. en-copyright= kn-copyright= en-aut-name=KawaiKoji en-aut-sei=Kawai en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 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=4 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=5 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=6 ORCID= en-aut-name=HiraideTakuya en-aut-sei=Hiraide en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SaitsuHirotomo en-aut-sei=Saitsu en-aut-mei=Hirotomo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 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 Pediatric Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Biochemistry, Hamamatsu University School of Medicine kn-affil= affil-num=8 en-affil=Department of Biochemistry, Hamamatsu University School of Medicine kn-affil= affil-num=9 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=GNAO1 variant kn-keyword=GNAO1 variant en-keyword=dystonic storm kn-keyword=dystonic storm en-keyword=globus pallidal stimulation kn-keyword=globus pallidal stimulation en-keyword=posterior reversible encephalopathy syndrome kn-keyword=posterior reversible encephalopathy syndrome END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=4 article-no= start-page=269 end-page=278 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=Femoral and Global Femoral Offset, but not Anteroposterior Offset, to Improve Postoperative Outcomes Following Total Hip Arthroplasty: Considerations Independent of the Contralateral Side en-subtitle= kn-subtitle= en-abstract= kn-abstract=The global femoral offset (the sum of the acetabular and femoral offsets) influences outcomes after total hip arthroplasty (THA). The optimal offset using plain radiographs has been reported, but internal and external rotations of the hip affect the offset value, producing unclear results when the nonsurgical side is not intact. We investigated the relationship between a functional hip score, i.e., the Harris Hip Score (HHS) and its effect on the post-THA anteroposterior and lateral offsets, and we sought to identify the optimal offset value. The cases of 158 patients with hemilateral hip osteoarthritis who underwent THA at a single center were retrospectively analyzed in this cross-sectional study. Three-dimensional pelvic and femoral models generated from computed tomography were used to examine several parameters, and the results revealed a significant binomial correlation among the modified HHS and femoral and global femoral offsets, with maximum values of 21.3 mm and 40 mm/100 cm body height, respectively. Pelvic and femoral parameters were measured and evaluated via alignment with a specific coordinate system. Our findings indicate that preoperative planning using these parameters may improve postoperative hip function, even when the nonoperative side is unsuitable for use as a reference, as in bilateral hip osteoarthritis cases. en-copyright= kn-copyright= en-aut-name=ImaiNorio en-aut-sei=Imai en-aut-mei=Norio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HiranoYuki en-aut-sei=Hirano en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HommaDaisuke en-aut-sei=Homma en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=EndoYuki en-aut-sei=Endo en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HorigomeYoji en-aut-sei=Horigome en-aut-mei=Yoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SuzukiHayato en-aut-sei=Suzuki en-aut-mei=Hayato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KawashimaHiroyuki en-aut-sei=Kawashima en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Division of Comprehensive Musculoskeletal Medicine, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=2 en-affil=Division of Orthopedic Surgery, Department of Regenerative and Transplant Medicine, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=3 en-affil=Division of Orthopedic Surgery, Department of Regenerative and Transplant Medicine, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=4 en-affil=Division of Orthopedic Surgery, Department of Regenerative and Transplant Medicine, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=5 en-affil=Division of Comprehensive Musculoskeletal Medicine, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=6 en-affil=Division of Orthopedic Surgery, Department of Regenerative and Transplant Medicine, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=7 en-affil=Division of Orthopedic Surgery, Department of Regenerative and Transplant Medicine, Niigata University Graduate School of Medical and Dental Sciences kn-affil= en-keyword=total hip arthroplasty kn-keyword=total hip arthroplasty en-keyword=global femoral offset kn-keyword=global femoral offset en-keyword=postoperative outcome kn-keyword=postoperative outcome en-keyword=three-dimensional analysis kn-keyword=three-dimensional analysis en-keyword=anteroposterior offset kn-keyword=anteroposterior offset END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=4 article-no= start-page=243 end-page=251 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=The Work Productivity of Cancer-survivor and Non-cancer-survivor Workers en-subtitle= kn-subtitle= en-abstract= kn-abstract=We investigated the work productivity levels of employed cancer survivors and non-cancer-survivor workers by conducting a cross-sectional study in Japan between February and March 2019, using an online survey. A total of 561 employed individuals aged 20-64 years were analyzed. Work productivity was assessed using the Work Productivity and Activity Impairment-General Health questionnaire which evaluates absenteeism, presenteeism, and overall work productivity loss. The questionnaire responses demonstrated that the cancer survivors within 1 year of diagnosis had significantly higher absenteeism compared to the non-cancer workers (p=0.048). Although presenteeism and overall work productivity loss were also higher in the non-cancer-survivor group, the differences were not significant. Cancer survivors within 1 year of diagnosis exhibited higher absenteeism, but their work productivity appeared to recover to levels comparable to those of the non-cancer workers over time. These findings may contribute to workplace policies supporting cancer survivors’ return to work. en-copyright= kn-copyright= en-aut-name=KamanoMika en-aut-sei=Kamano en-aut-mei=Mika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KandaKanae en-aut-sei=Kanda en-aut-mei=Kanae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NgatuNlandu Roger en-aut-sei=Ngatu en-aut-mei=Nlandu Roger kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MurakamiAkitsu en-aut-sei=Murakami en-aut-mei=Akitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamadoriYusuke en-aut-sei=Yamadori en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HiraoTomohiro en-aut-sei=Hirao en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Public Health, Faculty of Medicine, Kagawa University kn-affil= affil-num=2 en-affil=Department of Public Health, Faculty of Medicine, Kagawa University kn-affil= affil-num=3 en-affil=Department of Public Health, Faculty of Medicine, Kagawa University kn-affil= affil-num=4 en-affil=Cancer Center, Kagawa University Hospital kn-affil= affil-num=5 en-affil=Department of Anesthesiology, Faculty of Medicine, Kagawa University kn-affil= affil-num=6 en-affil=Department of Public Health, Faculty of Medicine, Kagawa University kn-affil= en-keyword=cancer survivor kn-keyword=cancer survivor en-keyword=work productivity kn-keyword=work productivity en-keyword=absenteeism kn-keyword=absenteeism en-keyword=presenteeism kn-keyword=presenteeism END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=4 article-no= start-page=231 end-page=242 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202508 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Bloodstream Infections Caused by Gram-Negative Bacteria in Geriatric Patients: Epidemiology, Antimicrobial Resistance and The Factors Affecting Mortality en-subtitle= kn-subtitle= en-abstract= kn-abstract=Bloodstream infections (BSIs) are an important cause of morbidity and mortality in geriatric patients. We retrospectively analyzed the cases of geriatric patients who developed BSIs due to gram-negative bacteria in order to evaluate the epidemiology, antimicrobial resistance, and the factors affecting mortality. The cases of 110 patients aged ≥ 65 years admitted to our hospital between January 1, 2017, and December 31, 2022 were assessed; 70 (63.6%) of the BSIs were healthcare-associated BSIs. The urinary system was the most common detectable source of infection at 43.6%. The most frequently isolated bacteria were Escherichia coli, Pseudomonas aeruginosa, and Klebsiella pneumoniae, in that order. Carbapenem resistance was detected in 17 patients (15.5%), and extended-spectrum beta-lactamase (ESBL) production from Enterobacterales family members was detected in 37 (51.4%) patients. Multivariate analysis revealed that (i) the probability of mortality in the patients with total bilirubin was increased by approx. sixfold and (ii) the likelihood of mortality for those with a Pitt bacteremia score (PBS) ≥ 4 points was approx. 17 times higher. PBS and simplified qPitt scores can help predict mortality and manage geriatric patients. There is a significant increase in mortality among patients with procalcitonin (PCT) levels at ≥ 2 nm/ml. en-copyright= kn-copyright= en-aut-name=KardanM Enes en-aut-sei=Kardan en-aut-mei=M Enes kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ErdemIlknur en-aut-sei=Erdem en-aut-mei=Ilknur kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YildizEmre en-aut-sei=Yildiz en-aut-mei=Emre kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KirazNuri en-aut-sei=Kiraz en-aut-mei=Nuri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ÇelikkolAliye en-aut-sei=Çelikkol en-aut-mei=Aliye kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Infectious Diseases, Faculty of Medicine, Namik Kemal University kn-affil= affil-num=2 en-affil=Department of Infectious Diseases, Faculty of Medicine, Namik Kemal University kn-affil= affil-num=3 en-affil=Department of Infectious Diseases, Faculty of Medicine, Namik Kemal University kn-affil= affil-num=4 en-affil=Department of Medical Microbiology, Faculty of Medicine, Namik Kemal University kn-affil= affil-num=5 en-affil=Department of Biochemistry, Faculty of Medicine, Namik Kemal University kn-affil= en-keyword=geriatrics kn-keyword=geriatrics en-keyword=gram-negative bacteria kn-keyword=gram-negative bacteria en-keyword=epidemiology kn-keyword=epidemiology en-keyword=antimicrobial resistance kn-keyword=antimicrobial resistance en-keyword=mortality kn-keyword=mortality END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=4 article-no= start-page=221 end-page=229 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202508 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Organ Donation after Extracorporeal Cardiopulmonary Resuscitation: Clinical and Ethical Perspectives en-subtitle= kn-subtitle= en-abstract= kn-abstract=Extracorporeal cardiopulmonary resuscitation (ECPR) has evolved into a life-saving therapy for select cardiac arrest patients, yet a growing body of evidence suggests it also holds promise as a bridge to organ donation in non-survivors. This review explores the clinical outcomes, ethical complexities, and evolving policies surrounding organ donation after ECPR. We summarize recent international and Japanese data demonstrating favorable graft function from ECPR donors, with the exception of lung transplantation. The ethical challenges — particularly those involving brain death determination on extracorporeal membrane oxygenation and adherence to the dead donor rule — are discussed in the context of Japan’s recent regulatory reforms. Additionally, we highlight the importance of structured end-of-life communication through multidisciplinary team meetings in facilitating ethically sound transitions from rescue efforts to donation pathways. Moving forward, improvements in donor management, standardized legal frameworks, and public and professional education are essential to optimizing the life-saving and life-giving potential of ECPR. en-copyright= kn-copyright= en-aut-name=YumotoTetsuya en-aut-sei=Yumoto en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NaitoHiromichi en-aut-sei=Naito en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HongoTakashi en-aut-sei=Hongo en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ObaraTakafumi en-aut-sei=Obara en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KosakiYoshinori en-aut-sei=Kosaki en-aut-mei=Yoshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AgetaKohei en-aut-sei=Ageta en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NojimaTsuyoshi en-aut-sei=Nojima en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TsukaharaKohei en-aut-sei=Tsukahara en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakaoAtsunori en-aut-sei=Nakao en-aut-mei=Atsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=brain death kn-keyword=brain death en-keyword=end-of-life care kn-keyword=end-of-life care en-keyword=ethical dilemmas kn-keyword=ethical dilemmas en-keyword=extracorporeal cardiopulmonary resuscitation kn-keyword=extracorporeal cardiopulmonary resuscitation END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250605 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Determinants of residual myometrial thickness after cesarean delivery: Comparative analysis of barbed versus conventional sutures—A sub‐analysis from the SPIRAL trial en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: This sub-analysis aimed to determine whether conventional suture-associated risk factors for cesarean scar defect show similar outcomes with barbed continuous suturing, and to identify factors influencing residual myometrial thickness when using barbed continuous sutures.
Methods: This sub-analysis of a multicenter, parallel-group, randomized controlled trial across four Japanese obstetrics and gynecology departments included 1211 women who had their first cesarean delivery between May 2020 and March 2023. Among them, 298 women underwent a C-section, with 253 follow-up through July 2023. Singleton pregnancies were randomly assigned to receive either barbed or conventional double-layered continuous sutures in a 1:1 ratio; they were monitored from consent through their 6- to 7-month check-up. The effects of cervical ripening, facility characteristics, and surgeon experience were investigated using a two-way ANOVA.
Results: Of the remaining 253 patients, 33 were lost to follow-up and 220 completed follow-up (110 per group). One institution enrolled the largest proportion of participants (45.9%), whereas two other institutions had more experienced surgeons. Two-way ANOVA revealed that surgeon experience (P = 0.020) and institutional factors (P < 0.001) significantly influenced the residual myometrial thickness at 6–7 months after surgery, whereas cervical dilation during active labor did not (P = 0.215). Additionally, a significant interaction was observed between institutional factors and suture type (barbed vs. conventional) on residual myometrial thickness (Pinteraction <0.001).
Conclusion: Institutional factors and surgeon experience represent significant determinants of residual myometrial thickness when using barbed sutures for cesarean closure, highlighting the importance of standardized surgical protocols and training across facilities. en-copyright= kn-copyright= en-aut-name=MakiJota en-aut-sei=Maki en-aut-mei=Jota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OobaHikaru en-aut-sei=Ooba en-aut-mei=Hikaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MitomaTomohiro en-aut-sei=Mitoma en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakatoHikari en-aut-sei=Nakato en-aut-mei=Hikari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SuemoriAyano en-aut-sei=Suemori en-aut-mei=Ayano kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KuriyamaChiaki en-aut-sei=Kuriyama en-aut-mei=Chiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SakataShujiro en-aut-sei=Sakata en-aut-mei=Shujiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MishimaSakurako en-aut-sei=Mishima en-aut-mei=Sakurako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OhiraAkiko en-aut-sei=Ohira en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=EtoEriko en-aut-sei=Eto en-aut-mei=Eriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MasuyamaHisashi en-aut-sei=Masuyama en-aut-mei=Hisashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=barbed suture kn-keyword=barbed suture en-keyword=cervical ripening kn-keyword=cervical ripening en-keyword=cesarean scar defect kn-keyword=cesarean scar defect en-keyword=cesarean scar disorder kn-keyword=cesarean scar disorder en-keyword=niche kn-keyword=niche en-keyword=residual myometrial thickness kn-keyword=residual myometrial thickness en-keyword=risk factors kn-keyword=risk factors END start-ver=1.4 cd-journal=joma no-vol=638 cd-vols= no-issue=8049 article-no= start-page=225 end-page=236 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250122 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Immune evasion through mitochondrial transfer in the tumour microenvironment en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cancer cells in the tumour microenvironment use various mechanisms to evade the immune system, particularly T cell attack1. For example, metabolic reprogramming in the tumour microenvironment and mitochondrial dysfunction in tumour-infiltrating lymphocytes (TILs) impair antitumour immune responses2,3,4. However, detailed mechanisms of such processes remain unclear. Here we analyse clinical specimens and identify mitochondrial DNA (mtDNA) mutations in TILs that are shared with cancer cells. Moreover, mitochondria with mtDNA mutations from cancer cells are able to transfer to TILs. Typically, mitochondria in TILs readily undergo mitophagy through reactive oxygen species. However, mitochondria transferred from cancer cells do not undergo mitophagy, which we find is due to mitophagy-inhibitory molecules. These molecules attach to mitochondria and together are transferred to TILs, which results in homoplasmic replacement. T cells that acquire mtDNA mutations from cancer cells exhibit metabolic abnormalities and senescence, with defects in effector functions and memory formation. This in turn leads to impaired antitumour immunity both in vitro and in vivo. Accordingly, the presence of an mtDNA mutation in tumour tissue is a poor prognostic factor for immune checkpoint inhibitors in patients with melanoma or non-small-cell lung cancer. These findings reveal a previously unknown mechanism of cancer immune evasion through mitochondrial transfer and can contribute to the development of future cancer immunotherapies. en-copyright=

kn-subject= en-title= kn-title=Implant-supported fixed prostheses with cantilever: a systematic review and meta-analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose This systematic review (SR) aimed to investigate whether the presence of a cantilever affects the results of implant treatment for partial edentulism, including an analysis of the anterior and posterior regions of the dental arches.
Methods An electronic search was performed, and original articles published between 1995 and November 2023 were included. The outcomes were the implant survival rate, patient satisfaction, occurrence of mechanical complications, and marginal bone loss around the implants. Two SR members independently examined the validity of the studies, extracted evidence from the included studies, and performed risk of bias assessment, comprehensive evidence evaluation, and meta-analysis.
Results Nine studies met our inclusion criteria. Implant survival rate tended to be lower in the cantilever group, and marginal bone loss tended to be higher in the cantilever group; however, there was no significant difference. There was no significant difference in patient satisfaction based on the presence or absence of a cantilever. Moreover, the incidence of mechanical complications was significantly higher in the cantilever group. According to the analysis of anterior and posterior regions, implant survival rate tended to be lower in the cantilever group of the posterior region, and marginal bone loss around the implants tended to be higher in the cantilever group of the anterior region.
Conclusion Implant-supported fixed prostheses with cantilevers did not negatively affect implant survival rate, marginal bone loss, or patient satisfaction. However, the incidence of mechanical complications significantly increased in the cantilever group. en-copyright= kn-copyright= en-aut-name=KondoYusuke en-aut-sei=Kondo en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakaiKiyoshi en-aut-sei=Sakai en-aut-mei=Kiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MinakuchiHajime en-aut-sei=Minakuchi en-aut-mei=Hajime kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HorimaiTakuya en-aut-sei=Horimai en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KubokiTakuo en-aut-sei=Kuboki en-aut-mei=Takuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=JSOI Clinical Guideline Working Group collaborators en-aut-sei=JSOI Clinical Guideline Working Group collaborators en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Clinical Guideline Task-Force Members (2018-), Japanese Society of Oral Implantology (JSOI) kn-affil= affil-num=2 en-affil=Clinical Guideline Task-Force Members (2018-), Japanese Society of Oral Implantology (JSOI) kn-affil= affil-num=3 en-affil=Department of Oral Rehabilitation and Implantology, Okayama University Hospital kn-affil= affil-num=4 en-affil=The Library, School of Dentistry, Nihon University kn-affil= affil-num=5 en-affil=Department of Oral Rehabilitation and Regenerative Medicine, Okayama University Faculty of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil= kn-affil= en-keyword=Cantilever kn-keyword=Cantilever en-keyword=Fixed prostheses kn-keyword=Fixed prostheses en-keyword=Implants kn-keyword=Implants en-keyword=Partial edentulism kn-keyword=Partial edentulism en-keyword=Systematic review kn-keyword=Systematic review END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=391 end-page=395 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=Trend of Digital Biomarkers (dBM) as Endpoints in Clinical Trials: Secondary Analysis of Open Data en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study examined clinical trial trends to guide digital biomarker (dBM) guideline development. Analysis of 2005–2023 data was conducted to assess the frequency and types of dBM used as endpoints (dEP) in these trials and the associated target diseases. Clinical trials using dEP increased from 0–7 per year (2005–2019) to 15–20 annually from 2020. Endocrine and metabolic conditions were the most common targets, showing a distinct disease distribution compared to overall trials. Most measurements used actigraphy devices or blood glucose sensors, with glucose sensors focusing on metabolic conditions while actigraphy covered broader applications. Additionally, 42.4% of trials used dEP as primary endpoints. While dEP use is growing, it remains limited in disease scope and device variety. Expanding both would enhance their utility in clinical research. en-copyright= kn-copyright= en-aut-name=MoritaMizuki en-aut-sei=Morita en-aut-mei=Mizuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HonjohMina en-aut-sei=Honjoh en-aut-mei=Mina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamaneTakahiro en-aut-sei=Yamane en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Biomedical Informatics, Faculty of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Health Sciences, Okayama University Medical School kn-affil= affil-num=3 en-affil=Department of Biomedical Informatics, Faculty of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=Clinical endpoint, kn-keyword=Clinical endpoint, en-keyword=clinical outcomes kn-keyword=clinical outcomes en-keyword=wearable devices kn-keyword=wearable devices END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=23 article-no= start-page=2715 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241202 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Predicting Surgical Site Infections in Spine Surgery: Association of Postoperative Lymphocyte Reduction en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: Postoperative lymphopenia is reported as an excellent indicator to predict surgical-site infection (SSI) after spine surgery. However, there is still controversy concerning which serological markers can predict spinal SSI. This study aims to evaluate excellent and early indicators for detecting SSI, focusing on spine instrumented surgery. Materials and Methods: This study included 268 patients who underwent spinal instrumented surgery from January 2022 to December 2023 (159 female and 109 male, average 62.9 years). The SSI group included 20 patients, and the non-SSI group comprised 248 patients. Surgical time, intraoperative blood loss, and glycemic levels were measured in both groups. The complete blood cell counts, differential counts, albumin, and C-reactive protein (CRP) levels were measured pre-surgery and postoperative on Days 1, 3, and 7. In comparing the groups, the Mann–Whitney U test analysis was used for continuous variables, while the chi-squared test and Fisher’s exact test were used for dichotomous variables. Results: The incidence of SSI after spinal instrumentation was 7.46% and was relatively higher in scoliosis surgery. The SSI group had significantly longer surgical times (248 min vs. 180 min, p = 0.0004) and a higher intraoperative blood loss (772 mL vs. 372 mL, p < 0.0001) than the non-SSI group. In the SSI group, the Day 3 (10.5 ± 6.2% vs. 13.8 ± 6.0%, p = 0.012) and Day 7 (14.4 ± 4.8% vs. 18.8 ± 7.1%, p = 0.012) lymphocyte ratios were lower than the non-SSI group. Albumin levels on Day 1 in the SSI group were lower than in the non-SSI group (2.94 ± 0.30 mg/dL vs. 3.09 ± 0.38 mg/dL, p = 0.045). There is no difference in CRP and lymphocyte count between the two groups. Conclusions: SSI patients had lower lymphocyte percentages than non-SSI patients, which was a risk factor for SSI, with constant high inflammation. The Day 3 lymphocyte percentage may predict SSI after spinal instrumented surgery. en-copyright= kn-copyright= en-aut-name=MiyamotoAkiyoshi en-aut-sei=Miyamoto en-aut-mei=Akiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaMasato en-aut-sei=Tanaka en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FloresAngel Oscar Paz en-aut-sei=Flores en-aut-mei=Angel Oscar Paz kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YuDongwoo en-aut-sei=Yu en-aut-mei=Dongwoo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=JainMukul en-aut-sei=Jain en-aut-mei=Mukul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HengChristan en-aut-sei=Heng en-aut-mei=Christan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KomatsubaraTadashi en-aut-sei=Komatsubara en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AratakiShinya en-aut-sei=Arataki en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OdaYoshiaki en-aut-sei=Oda en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ShinoharaKensuke en-aut-sei=Shinohara en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=UotaniKoji en-aut-sei=Uotani en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=2 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=3 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=4 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=5 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=6 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=7 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=8 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=9 en-affil=Department of Orthopedic Surgery, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Orthopedic Surgery, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Orthopedic Surgery, Okayama University Hospital kn-affil= en-keyword=surgical site infection kn-keyword=surgical site infection en-keyword=spine surgery kn-keyword=spine surgery en-keyword=instrumentation kn-keyword=instrumentation en-keyword=diagnosis kn-keyword=diagnosis en-keyword=lymphocyte kn-keyword=lymphocyte END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=5 article-no= start-page=468 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250506 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Distribution of Fimbrial Genes and Their Association with Virulence and Levofloxacin Resistance/Extended-Spectrum Beta-Lactamase Production in Uropathogenic Escherichia coli en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Urinary tract infection (UTI) is predominantly caused by uropathogenic Escherichia coli (UPEC). Previous studies have reported that the fimbriae of UPEC are involved in virulence and antimicrobial resistance. We aimed to analyze the fimbrial gene profiles of UPEC and investigate the specificity of these expressions in symptomatic UTI, urinary device use, and levofloxacin (LVFX) resistance/extended-spectrum beta-lactamase (ESBL) production. Methods: A total of 120 UPEC strains were isolated by urine culture between 2019 and 2023 at our institution. They were subjected to an antimicrobial susceptibility test and polymerase chain reaction (PCR) to identify 14 fimbrial genes and their association with clinical outcomes or antimicrobial resistance. Results: The prevalence of the papG2 gene was significantly higher in the symptomatic UTI group by multivariate analyses (OR 5.850, 95% CI 1.390–24.70, p = 0.016). The prevalence of the c2395 gene tended to be lower in the symptomatic UTI group with urinary devices (all p < 0.05). In LVFX-resistant UPEC strains from both the asymptomatic bacteriuria (ABU) and the symptomatic UTI group, the expression of the papEF, papG3, c2395, and yadN genes tended to be lower (all p < 0.05). Conclusion: The fimbrial genes of UPEC are associated with virulence and LVFX resistance, suggesting that even UPEC with fewer motility factors may be more likely to ascend the urinary tract in the presence of the urinary devices. These findings may enhance not only the understanding of the virulence of UPEC but also the management of UTI. en-copyright= kn-copyright= en-aut-name=MitsuiMasao en-aut-sei=Mitsui en-aut-mei=Masao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=MaruhashiMai en-aut-sei=Maruhashi en-aut-mei=Mai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MaruyamaYuki en-aut-sei=Maruyama en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IwataTakehiro en-aut-sei=Iwata en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TominagaYusuke en-aut-sei=Tominaga en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KatayamaSatoshi en-aut-sei=Katayama en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NishimuraShingo en-aut-sei=Nishimura en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=BekkuKensuke en-aut-sei=Bekku en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 ORCID= en-aut-name=HirakawaHidetada en-aut-sei=Hirakawa en-aut-mei=Hidetada kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=SadahiraTakuya en-aut-sei=Sadahira en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 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 Bacteriology, Graduate School of Medicine, Gunma University kn-affil= affil-num=4 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Bacteriology, Graduate School of Medicine, Gunma University kn-affil= affil-num=12 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=fimbriae kn-keyword=fimbriae en-keyword=urinary tract infection kn-keyword=urinary tract infection en-keyword=drug resistance kn-keyword=drug resistance en-keyword=virulence kn-keyword=virulence en-keyword=uropathogenic Escherichia coli kn-keyword=uropathogenic Escherichia coli END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=3 article-no= start-page=444 end-page=451 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250630 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=More postoperative complications and revision surgery after occipitocervical fusion than after atlantoaxial fusion: a retrospective multicenter cohort study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Study Design: A retrospective multicenter cohort study.
Purpose: We sought to determine whether occipitocervical (OC) fusion is followed by more postoperative complications and revision surgery than is atlantoaxial (AA) fusion. We aim to compare postoperative complications and revision surgery associated with OC fusion and AA fusion.
Overview of Literature: OC and AA fusion are established techniques for restoring upper cervical stability. However, the outcomes of the two methods have not been compared.
Methods: This study included 90 patients who underwent upper spinal fusion surgery for mechanical instability, performed by three surgeons in two hospitals from 2011 to 2023; OC fusion was indicated for irreducible AA subluxation, os odontoideum, and severe upper C1 fracture. Of the patients, 38 (mean age, 58.7 years) underwent OC fusion, and 52 (mean age, 62.8 years) underwent AA fusion. To evaluate surgical outcomes, we documented surgical time, intraoperative blood loss, postoperative complications, and the rate of revision surgery. Radiographs were obtained to identify screw malposition, rod breakage, and nonunion. To compare the outcomes of the two techniques, we used the Mann-Whitney U test for continuous variables and the chi-square or Fisher’s exact test for dichotomous variables.
Results: OC fusion took significantly longer (175.4 minutes) than AA fusion (150.7 minutes, p=0.020) and had a higher complication rate (39.5% vs. 11.5%, p<0.0001). The reoperation rate was 23.7% (9/38) after OC fusion and 3.8% (2/52) after AA fusion; the difference was statistically significant (p=0.0073). Average amounts of blood loss were 224 mL during OC fusion and 224 mL during AA fusion; the difference was not significant (p=0.947).
Conclusions: Although OC fusion is indispensable for certain conditions, particularly basilar invagination, it entails more risk than dose AA fusion; the choice of technique thus warrants careful consideration. en-copyright= kn-copyright= en-aut-name=UotaniKoji en-aut-sei=Uotani en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FloresAngel Oscar Paz en-aut-sei=Flores en-aut-mei=Angel Oscar Paz kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaMasato en-aut-sei=Tanaka en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=EkadeShashank J en-aut-sei=Ekade en-aut-mei=Shashank J kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AratakiShinya en-aut-sei=Arataki en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KomatsubaraTadashi en-aut-sei=Komatsubara en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OdaYoshiaki en-aut-sei=Oda en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ShinoharaKensuke en-aut-sei=Shinohara en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= en-keyword=Occipitocervical fusion kn-keyword=Occipitocervical fusion en-keyword=Atlantoaxial fusion kn-keyword=Atlantoaxial fusion en-keyword=Upper cervical instability kn-keyword=Upper cervical instability en-keyword=Surgical complication kn-keyword=Surgical complication en-keyword=Reoperation kn-keyword=Reoperation END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=222 end-page=234 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=2023 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=vkTracer: Vulnerable Kernel Code Tracing to Generate Profile of Kernel Vulnerability en-subtitle= kn-subtitle= en-abstract= kn-abstract=Vulnerable kernel codes are a threat to an operating system kernel. An adversary’s user process can forcefully invoke a vulnerable kernel code to cause privilege escalation or denial of service (DoS). Although service providers or security operators have to determine the effect of kernel vulnerabilities on their environment to decide the kernel updating, the list of vulnerable kernel codes are not provided from the common vulnerabilities and exposures (CVE) report. It is difficult to identify the vulnerable kernel codes from the exploitation result of the kernel which indicates the account information or the kernel suspension. To identify the details of kernel vulnerabilities, this study proposes a vulnerable kernel code tracer (vkTracer), which employs an alternative viewpoint using proof-of-concept (PoC) code to create a profile of kernel vulnerability. vkTracer traces the user process of the PoC code and the running kernel to hook the invocation of the vulnerable kernel codes. Moreover, vkTracer extracts the whole kernel component’s information using the running and static kernel image and debug section. The evaluation results indicated that vkTracer could trace PoC code executions (e.g., privilege escalation and DoS), identify vulnerable kernel codes, and generate kernel vulnerability profiles. Furthermore, the implementation of vkTracer revealed that the identification overhead ranged from 5.2683 s to 5.2728 s on the PoC codes and the acceptable system call latency was 3.7197 μs. en-copyright= kn-copyright= en-aut-name=KuzunoHiroki en-aut-sei=Kuzuno en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamauchiToshihiro en-aut-sei=Yamauchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Engineering, Kobe University kn-affil= affil-num=2 en-affil=Faculty of Natural Science and Technology, Okayama University kn-affil= en-keyword=Kernel vulnerability kn-keyword=Kernel vulnerability en-keyword=Dynamic analysis kn-keyword=Dynamic analysis en-keyword=System security kn-keyword=System security END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=3 article-no= start-page=e70143 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250625 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Factors Influencing Pain Management Practices Among Nurses in University Hospitals in Western Japan: A Cross‐Sectional Study Using Hierarchical Multiple Regression Analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Effective pain management remains a global nursing challenge, requiring awareness of influencing factors. This cross-sectional study examined such factors among nurses in Western Japan's university hospitals from September to November 2023. A self-reported questionnaire was used to investigate nurses' sociodemographic characteristics, collaboration with physicians in the ward, pain management knowledge, empathy, and pain management practices. Among 695 nurses (69.4% valid response rate), 51.4% had under 5 years' work experience, indicating a relatively junior nursing workforce. The mean practice score was 47.5 (SD = 7.1). Hierarchical regression showed knowledge and empathy increased practice scores by 6.2%. Nurses' empathy, particularly their perspective-taking, explained pain management practice (β = 0.242, p < 0.001). Information-sharing with pain specialists, effective collaboration with physicians in the ward, work experience, and clinical pain education were also associated with pain management practices (all p < 0.05). This study suggests that enhancing nurses' empathy and fostering a collaborative ward environment may be essential strategies to improve the pain management quality. en-copyright= kn-copyright= en-aut-name=XiMengyao en-aut-sei=Xi en-aut-mei=Mengyao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KajiwaraYuki en-aut-sei=Kajiwara en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MorimotoMichiko en-aut-sei=Morimoto en-aut-mei=Michiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Doctor's Program, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Health Sciences, Okayama University kn-affil= en-keyword=collaboration kn-keyword=collaboration en-keyword=empathy kn-keyword=empathy en-keyword=nurse kn-keyword=nurse en-keyword=pain management practice kn-keyword=pain management practice END start-ver=1.4 cd-journal=joma no-vol=71 cd-vols= no-issue=3 article-no= start-page=321 end-page=343 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250220 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Physiological and Biochemical Traits of Dormancy Release and Growth Resumption in Japanese Cedar in the Warm-Temperate Zone en-subtitle= kn-subtitle= en-abstract= kn-abstract=Global warming will disturb dormancy release and growth resumption of trees. To better understand this process, it is important to investigate physiological and biochemical traits related to these stages. We examined dormancy release and growth resumption in Japanese cedar (Cryptomeria japonica [L.] D. Don), an evergreen needle-leaved tree, in the warm-temperate zone by evaluating budbreak under growth-promoting conditions, and simultaneously examining respiration rates and contents of carbohydrates and phytohormones in shoots from November 2022 to March 2023. A long time to budbreak and the lowest budbreak rates of 75% in November indicated shallow dormancy. Budbreak rates of 98%, short time to budbreak, and first appearance of budbreak in the field in March indicated growth resumption. Continuous changes in budbreak rates and time to budbreak between dormancy and growth resumption indicated dormancy was gradually released. Surges in budbreak rates in December indicated dormancy was almost completely released by early winter. Contents of abscisic acid (ABA) and salicylic acid (SA) decreased from November, remained low in March, and were strongly associated with budbreak rates according to principal component analysis. It was suggested that the depletion of SA led to the depletion of ABA, contributing to dormancy release and growth resumption. Fructose and trans-zeatin accumulated until February, and low levels of starch, indole-3-acetic acid, jasmonic acid, and jasmonic acid-isoleucine during winter was followed by accumulation in March. Although these biochemical traits were less related to budbreak rates compared to ABA and SA, they seemed to assist either dormancy release or growth resumption. en-copyright= kn-copyright= en-aut-name=HiejimaShoma en-aut-sei=Hiejima en-aut-mei=Shoma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SeinoHiroto en-aut-sei=Seino en-aut-mei=Hiroto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HachisukaRico en-aut-sei=Hachisuka en-aut-mei=Rico kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WatanabeYuka en-aut-sei=Watanabe en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MatsuuraTakakazu en-aut-sei=Matsuura en-aut-mei=Takakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MoriIzumi C. en-aut-sei=Mori en-aut-mei=Izumi C. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=UgawaShin en-aut-sei=Ugawa en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=The United Graduate School of Agricultural Sciences, Kagoshima University kn-affil= affil-num=2 en-affil=Graduate School of Agriculture, Forestry and Fisheries, Kagoshima University kn-affil= affil-num=3 en-affil=The United Graduate School of Agricultural Sciences, Kagoshima University kn-affil= affil-num=4 en-affil=Graduate School of Agriculture, Forestry and Fisheries, Kagoshima University kn-affil= affil-num=5 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=6 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=7 en-affil=The United Graduate School of Agricultural Sciences, Kagoshima University kn-affil= en-keyword=Japanese cedar kn-keyword=Japanese cedar en-keyword=Warm-temperate zone kn-keyword=Warm-temperate zone en-keyword=Dormancy release kn-keyword=Dormancy release en-keyword=Growth resumption kn-keyword=Growth resumption en-keyword=Physio-biochemical traits kn-keyword=Physio-biochemical traits END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=292 end-page=297 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231127 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Analyzing Post-injection Attacker Activities in IoT Devices: A Comprehensive Log Analysis Approach en-subtitle= kn-subtitle= en-abstract= kn-abstract=With the continuous proliferation of Internet of Things (IoT) devices, malware threats that specifically target these devices continue to increase. The urgent need for robust security measures is predicated on a comprehensive understanding of the behavioral patterns of IoT malware. However, previous studies have often overlooked the analysis of command sequences in Telnet logs. This study bridges this research gap by examining the post-injection behaviors of attackers. By analyzing a vast dataset comprising more than ten million logs collected from an IoT honeypot, we reveal three distinct post-injection activity patterns, each with unique characteristics. These patterns provide pivotal insights that not only help distinguish between legitimate operations and attempted attacks, but also drive the development of robust cybersecurity measures that effectively deter such behaviors. The nuances discovered in this study contribute significantly to IoT security by enhancing our understanding of malware tactics and informing targeted defense strategies. en-copyright= kn-copyright= en-aut-name=VictorHervet en-aut-sei=Victor en-aut-mei=Hervet kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KobayashiSatoru en-aut-sei=Kobayashi en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamauchiToshihiro en-aut-sei=Yamauchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=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=Malware analysis kn-keyword=Malware analysis en-keyword=IoT kn-keyword=IoT en-keyword=Honeypot kn-keyword=Honeypot en-keyword=Log analysis kn-keyword=Log analysis en-keyword=Attack patterns kn-keyword=Attack patterns END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=274 end-page=278 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231127 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Prevention Method for Stack Buffer Overflow Attack in TA Command Calls in OP-TEE en-subtitle= kn-subtitle= en-abstract= kn-abstract=TEE systems provide normal world and secure world. It is impossible to gain access to the secure world directly from the normal world. However, vulnerabilities in the secure world can cause attacks to compromise the secure world. In this study, we investigate the security features applied to trusted applications (TA) in OP-TEE and clarify the lack of protection against stack buffer overflow in TA command calls. We also propose a method for preventing attacks that exploit stack buffer overflows in TA command calls. In addition, the experimental results show that attacks on the vulnerable TAs can be prevented with the proposed method and the overhead can be evaluated. en-copyright= kn-copyright= en-aut-name=ShibaKaito en-aut-sei=Shiba en-aut-mei=Kaito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KuzunoHiroki en-aut-sei=Kuzuno en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamauchiToshihiro en-aut-sei=Yamauchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Engineering, Kobe University kn-affil= affil-num=3 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Trusted execution environment kn-keyword=Trusted execution environment en-keyword=Stack overflow prevention method kn-keyword=Stack overflow prevention method en-keyword=System security kn-keyword=System security END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=161 end-page=167 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231128 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluation of Effectiveness of MAC Systems Based on LSM for Protecting IoT Devices en-subtitle= kn-subtitle= en-abstract= kn-abstract=Numerous active attacks targeting Internet of Things (IoT) devices exist. They exploit the latest vulnerabilities discovered in IoT devices. Therefore, Mandatory Access Control (MAC) systems based on Linux Security Modules (LSM), such as SELinux and AppArmor, are effective security features for IoT devices because they can mitigate the impact of attacks even if software vulnerabilities are discovered. However, they are not adopted by most IoT devices. The existing approaches are insufficient for investigating the causes of this problem.In this study, we comprehensively investigated what factors can affect the applicability of MAC systems based on LSM in IoT devices. We focused on how frequently cases can occur where they cannot be adopted, owing to each factor. To increase the comprehensiveness of the factors affecting the adoption of MAC systems in IoT devices, we investigated the kernel version, CPU architecture, and support for BusyBox in addition to the investigation of resources, which conducted in previous studies. We also conducted simulated experiments based on the attack method of Mirai to investigate whether MAC systems can protect against IoT malware. Finally, we discuss the impact of a combination of these factors on MAC system adoption. en-copyright= kn-copyright= en-aut-name=MikiMasato en-aut-sei=Miki en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamauchiToshihiro en-aut-sei=Yamauchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KobayashiSatoru en-aut-sei=Kobayashi en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=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=Mandatory Access Control System kn-keyword=Mandatory Access Control System en-keyword=IoT Security kn-keyword=IoT Security en-keyword=Linux Security Modules kn-keyword=Linux Security Modules END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=236 end-page=244 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230623 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Non Real-Time Data Transmission Performance Analysis of PROFINET for Assuring Data Transmission Quality en-subtitle= kn-subtitle= en-abstract= kn-abstract=The industrial Ethernet PROFINET supports three different data transmission modes: isochronous real-time (IRT), real-time (RT), and non real-time (NRT) transmitting data requiring hard, soft, and no real-time performances, respectively. The data transmission latency in the NRT increased with the amount of data transmission in the IRT, RT, and NRT. Therefore, the quality of data transmission in NRT may degrade as the amount of data transmission in IRT, RT, and NRT increases. In this study, we derived the average data transmission latency in an NRT with data transmission in IRT and RT by applying stochastic processes. This allowed us to maintain the quality of data transmission in the NRT by adjusting the number of devices connected to the network and the number of applications transmitting data in the NRT so that the average latency of data in the NRT does not exceed a certain value. en-copyright= kn-copyright= en-aut-name=NorimatsuTakashi en-aut-sei=Norimatsu en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamauchiToshihiro en-aut-sei=Yamauchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Industrial Ethernet kn-keyword=Industrial Ethernet en-keyword=PROFINET kn-keyword=PROFINET en-keyword=Non Real Time kn-keyword=Non Real Time en-keyword=Real-Time kn-keyword=Real-Time en-keyword=Isochronous Real Time kn-keyword=Isochronous Real Time END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=267 end-page=273 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231127 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Supporting Multiple OS Types on Estimation of System Call Hook Point by Virtual Machine Monitor en-subtitle= kn-subtitle= en-abstract= kn-abstract=Methods to hook system calls issued by a guest operating system (OS) running on a virtual machine using a virtual machine monitor are proposed. The address of the hook point is derived from the guest OS’s source code and established prior to the kernel startup process. Due to changes in system call processing in OS updates and address space layout randomization, the addresses of these hook points cannot always be pre-determined before the kernel startup process. To address this challenge, a method for estimating the system call hook point is proposed in Linux by analyzing the guest OS memory on x86-64 CPUs rather than pre-calculation. Although the method supports Linux, the method can be extended to support other OS types. In this paper, we propose a method to extend the method to support additional OSes. Specifically, we present analysis results and a novel method for estimating hook points on FreeBSD, NetBSD, and OpenBSD. The effectiveness of our proposed method is also demonstrated through evaluation. en-copyright= kn-copyright= en-aut-name=SatoMasaya en-aut-sei=Sato en-aut-mei=Masaya kn-aut-name= kn-aut-sei=

citrate dextrose solution A en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Large-volume leukocytapheresis is time consuming. The upper limit of the inlet flow rate is determined by the inlet: anticoagulant (AC) ratio and can be changed by combining the AC with heparin. Here, we devised a protocol to increase the AC ratio using a highly concentrated sodium citrate solution without heparin.
Study Design and Methods: We collected data from 40 consecutive apheresis procedures performed using the Spectra Optia system on 40 donors for allogeneic peripheral blood stem cells between June 2022 and June 2023. We used AC containing 2.2% sodium citrate (normal concentrated sodium citrate [NSC]) and 5.32% sodium citrate (highly concentrated sodium citrate [HSC]). The AC ratios were set to 12:1 and 24:1 for the NSC and HSC, respectively.
Results: The processed volume was not different; the maximum inlet flow rate increased, the total processing time was reduced, the AC solution used was reduced, and the product volume was reduced in the HSC group, compared to the NSC group. Although the CD34+ cell CE2 was reduced in the HSC group, no difference was observed in the number of collected CD34+ cells. The incidences of citrate-related reactions were similar.
Discussion: We propose a novel leukocytapheresis method using HSC that shortens the procedure time and reduces the amount of AC solution used compared to the conventional method en-copyright= kn-copyright= en-aut-name=AbeMasaya en-aut-sei=Abe en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiiKeiko en-aut-sei=Fujii en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KitamuraWataru en-aut-sei=Kitamura en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IkeuchiKazuhiro en-aut-sei=Ikeuchi en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FukumiTakuya en-aut-sei=Fukumi en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WashioKana en-aut-sei=Washio en-aut-mei=Kana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=FujiiNobuharu en-aut-sei=Fujii en-aut-mei=Nobuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Division of Transfusion and Cell Therapy, Okayama University Hospital kn-affil= affil-num=2 en-affil=Division of Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=3 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=4 en-affil=Division of Transfusion and Cell Therapy, Okayama University Hospital kn-affil= affil-num=5 en-affil=Division of Transfusion and Cell Therapy, Okayama University Hospital kn-affil= affil-num=6 en-affil=Division of Transfusion and Cell Therapy, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Pediatric Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Division of Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Division of Transfusion and Cell Therapy, Okayama University Hospital kn-affil= en-keyword=anticoagulant kn-keyword=anticoagulant en-keyword=apheresis kn-keyword=apheresis en-keyword=high sodium citrate concentration kn-keyword=high sodium citrate concentration en-keyword=Spectra Optia kn-keyword=Spectra Optia END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=1 article-no= start-page=364 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250513 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Efficient diagnosis for endoscopic remission in Crohn's diseases by the combination of three non-invasive markers en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Serum C-reactive protein (CRP), leucine-rich alpha-2 glycoprotein (LRG), and fecal calprotectin (Fcal) are non-invasive markers used to assess Crohn's disease (CD) severity. However, the accuracy of these markers alone is often limited, and most previous reports have evaluated the efficacy of each marker individually. We aimed to improve the diagnostic performance of endoscopic remission (ER) of CD by combining these 3 markers.
Methods We tested the diagnostic ability of various combinations of these 3 markers for endoscopic severity in 230 consecutive patients with CD from September 2014 to July 2023. The modified Simple Endoscopic Score for Crohn's disease (mSES-CD) was used to determine endoscopic severity.
Results Each of the 3 markers was correlated with mSED-CD (LRG: r = 0.69, CRP: r = 0.60, and Fcal: r = 0.67). A combination of 2 of the 3 markers did not increase the diagnostic accuracy of ER. However, by combining all 3 markers, the diagnostic ability for ER was improved in comparison to the diagnostic ability of the 3 individual markers, assuming that ER was obtained if 2 or 3 markers were negative. The sensitivity, specificity, and accuracy were 89%, 83%, and 86%, respectively. Additionally, we established a 2-step method using Fcal values after evaluating the 2 serum markers. This method was most useful for reducing both the patient burden and costs.
Conclusions The newly established 2-step method allowed for a higher accuracy in the non-invasive diagnosis of ER when the 3 markers were combined. en-copyright= kn-copyright= en-aut-name=TakeiKensuke en-aut-sei=Takei en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 ORCID= en-aut-name=IshiguroMikako en-aut-sei=Ishiguro en-aut-mei=Mikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ToyosawaJunki en-aut-sei=Toyosawa en-aut-mei=Junki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AoyamaYuki en-aut-sei=Aoyama en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IgawaShoko en-aut-sei=Igawa en-aut-mei=Shoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakeuchiKeiko en-aut-sei=Takeuchi en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YamasakiYasushi en-aut-sei=Yamasaki en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KinugasaHideaki en-aut-sei=Kinugasa en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TakaharaMasahiro en-aut-sei=Takahara en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KawanoSeiji en-aut-sei=Kawano en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 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=14 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Research Center for Intestinal Health Science, Okayama University kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=14 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=CD, Crohn's disease kn-keyword=CD, Crohn's disease en-keyword=LRG, Leucine-rich alpha-2 glycoprotein kn-keyword=LRG, Leucine-rich alpha-2 glycoprotein en-keyword=Fcal, Fecal calprotectin kn-keyword=Fcal, Fecal calprotectin en-keyword=CRP, C-reactive protein kn-keyword=CRP, C-reactive protein en-keyword=ER, Endoscopic remission kn-keyword=ER, Endoscopic remission END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=3 article-no= start-page=213 end-page=219 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=A Case of Chromophobe Renal Cell Carcinoma Metastasizing to the Cervical Lymph Nodes after Long-term Follow-up en-subtitle= kn-subtitle= en-abstract= kn-abstract=Renal cell carcinoma (RCC) can metastasize hematogenously and recur after a long dormancy. Chromophobe RCC metastasized to the cervical lymph nodes 10 years after the primary resection in a woman who underwent nephrectomy for RCC (T1aN0M0 stage I). Metastatic RCC diagnosis was confirmed by aspiration. The lymph node mass was resected, and the tumor cells matched chromophobe RCC metastasis. No adjuvant therapy was administered due to the lack of evidence regarding adjuvant therapy for chromophobe RCC. Long-term surveillance is crucial in RCC because of the possibility of late metastasis. We reviewed the clinical aspects and literature on metastatic cervical RCC. en-copyright= kn-copyright= en-aut-name=WatanabeMakoto en-aut-sei=Watanabe en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OgawaTomoyuki en-aut-sei=Ogawa en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KobayashiKanao en-aut-sei=Kobayashi en-aut-mei=Kanao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KatsuyaNarutaka en-aut-sei=Katsuya en-aut-mei=Narutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IshikawaAkira en-aut-sei=Ishikawa en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HamamotoTakao en-aut-sei=Hamamoto en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TaharaHiroaki en-aut-sei=Tahara en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UedaTsutomu en-aut-sei=Ueda en-aut-mei=Tsutomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TakenoSachio en-aut-sei=Takeno en-aut-mei=Sachio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Otolaryngology, Chugoku Rosai Hospital kn-affil= affil-num=2 en-affil=Department of Otolaryngology, Chugoku Rosai Hospital kn-affil= affil-num=3 en-affil=Department of Nephrology and Urological Surgery, Chugoku Rosai Hospital kn-affil= affil-num=4 en-affil=Department of Molecular Pathology, Graduate School of Medical Sciences, Hiroshima University kn-affil= affil-num=5 en-affil=Department of Molecular Pathology, Graduate School of Medical Sciences, Hiroshima University kn-affil= affil-num=6 en-affil=Department of Otolaryngology and Head and Neck Surgery, Hiroshima University Hospital kn-affil= affil-num=7 en-affil=Department of Otolaryngology and Head and Neck Surgery, Hiroshima University Hospital kn-affil= affil-num=8 en-affil=Department of Otolaryngology and Head and Neck Surgery, Hiroshima University Hospital kn-affil= affil-num=9 en-affil=Department of Otolaryngology and Head and Neck Surgery, Hiroshima University Hospital kn-affil= en-keyword=renal cell carcinoma kn-keyword=renal cell carcinoma en-keyword=cervical lymph node metastasis kn-keyword=cervical lymph node metastasis en-keyword=late recurrence kn-keyword=late recurrence en-keyword=head and neck kn-keyword=head and neck END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=3 article-no= start-page=205 end-page=208 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=An Asymptomatic Perigraft Seroma in a Patient who Underwent Aortic Root Replacement for Annulo-Aortic Ectasia en-subtitle= kn-subtitle= en-abstract= kn-abstract=Perigraft seroma, a sterile fluid accumulation around the graft, is a potential complication after thoracic aortic surgery. The optimal treatment strategy for a perigraft seroma with vascular compression after thoracic aortic surgery has been unclear. We describe the case of a 62-year-old Japanese male in whom an asymptomatic perigraft seroma was observed after he had undergone aortic root replacement for annulo-aortic ectasia. The seroma was successfully treated with thoracoscopic drainage and conservative therapy. Less invasive therapy, including conservative therapy, may also be an option for asymptomatic perigraft seromas observed after thoracic aortic surgery. en-copyright= kn-copyright= en-aut-name=FujitaYasufumi en-aut-sei=Fujita en-aut-mei=Yasufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShimizuShuji en-aut-sei=Shimizu en-aut-mei=Shuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Cardiovascular Surgery, Kure Kyosai Hospital kn-affil= affil-num=2 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=perigraft seroma kn-keyword=perigraft seroma en-keyword=aortic root replacement kn-keyword=aortic root replacement en-keyword=thoracoscopic drainage kn-keyword=thoracoscopic drainage en-keyword=conservative therapy kn-keyword=conservative therapy END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=3 article-no= start-page=167 end-page=176 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=Promising Effectiveness of Combined Chemotherapy and Immunotherapy in Patients with Advanced Non-small Cell Lung Cancer: A Real-World Prospective Observational Study (CS-Lung-003) en-subtitle= kn-subtitle= en-abstract= kn-abstract=This prospective observational study investigated the clinical status of patients with advanced non-small cell lung cancer (NSCLC) treated with cytotoxic chemotherapy+an immune checkpoint inhibitor (chemo + IO) as first-line treatment in a real-world setting. The cases of 98 patients treated with chemo + IO were prospectively collected and analyzed for effectiveness and safety. The response rate to chemo + IO was 46.9%, and the disease control rate was 76.5%. The median progression-free survival and overall survival (OS) in the total population were 5.2 and 22.3 months, respectively. The patients positive for PD-L1 (≥ 1%) showed significantly longer OS than the negative group (<1%) (median 26.7 vs. 18.7 months, p=0.04). Pre-existing interstitial lung disease (ILD) was associated with shorter OS than the absence of ILD (median 9.0 vs. 22.6 months, p<0.01). Immunerelated adverse events (irAEs) were observed in 28 patients (28.6%). The most frequent irAE was ILD (n=11); Grade 1 (n=1 patient), G2 (n=5), G3 (n=4), and only a single patient with a G5 irAE. In this CS-Lung-003 study, first-line chemo + IO in a real-world setting showed good effectiveness, comparable to that observed in international clinical trials. In real-world practice, chemo + IO is a promising and steadfast strategy. en-copyright= kn-copyright= en-aut-name=KanajiNobuhiro en-aut-sei=Kanaji en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishiiKazuya en-aut-sei=Nishii en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsubataYukari en-aut-sei=Tsubata en-aut-mei=Yukari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakaoMika en-aut-sei=Nakao en-aut-mei=Mika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkunoTakae en-aut-sei=Okuno en-aut-mei=Takae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OkawaSachi en-aut-sei=Okawa en-aut-mei=Sachi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakataKenji en-aut-sei=Takata en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KodaniMasahiro en-aut-sei=Kodani en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YamasakiMasahiro en-aut-sei=Yamasaki en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=FujitakaKazunori en-aut-sei=Fujitaka en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KubotaTetsuya en-aut-sei=Kubota en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=InoueMasaaki en-aut-sei=Inoue en-aut-mei=Masaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=WatanabeNaoki en-aut-sei=Watanabe en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=HottaKatsuyuki en-aut-sei=Hotta en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=CS-Lung-003 Investigator en-aut-sei=CS-Lung-003 Investigator en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil=Department of Internal Medicine, Division of Hematology, Rheumatology and Respiratory Medicine, Faculty of Medicine, Kagawa University kn-affil= affil-num=2 en-affil=Department of Respiratory Medicine, National Hospital Organization Iwakuni Clinical Center kn-affil= affil-num=3 en-affil=Department of Internal Medicine, Division of Medical Oncology and Respiratory Medicine, Shimane University Faculty of Medicine kn-affil= affil-num=4 en-affil=Department of Internal Medicine, Division of Medical Oncology and Respiratory Medicine, Shimane University Faculty of Medicine kn-affil= affil-num=5 en-affil=Department of Internal Medicine, Division of Medical Oncology and Respiratory Medicine, Shimane University Faculty of Medicine kn-affil= affil-num=6 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=8 en-affil=Division of Medical Oncology and Molecular Respirology, Faculty of Medicine, Tottori University kn-affil= affil-num=9 en-affil=Department of Respiratory Disease, Hiroshima Red Cross Hospital and Atomic-Bomb Survivors Hospital kn-affil= affil-num=10 en-affil=Department of Molecular and Internal Medicine, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=11 en-affil=Department of Respiratory Medicine and Allergology, Kochi University kn-affil= affil-num=12 en-affil=Department of Chest Surgery, Shimonoseki City Hospital kn-affil= affil-num=13 en-affil=Department of Internal Medicine, Division of Hematology, Rheumatology and Respiratory Medicine, Faculty of Medicine, Kagawa University kn-affil= affil-num=14 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=15 en-affil= kn-affil= en-keyword=non-small cell lung cancer kn-keyword=non-small cell lung cancer en-keyword=real-world kn-keyword=real-world en-keyword=first-line kn-keyword=first-line en-keyword=immune checkpoint inhibitor kn-keyword=immune checkpoint inhibitor en-keyword=combined immunotherapy kn-keyword=combined immunotherapy END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=3 article-no= start-page=157 end-page=166 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=Continuous Stimulation with Glycolaldehyde-derived Advanced Glycation End Product Reduces Aggrecan and COL2A1 Production via RAGE in Human OUMS-27 Chondrosarcoma Cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Chondrocytes are responsible for the production of extracellular matrix (ECM) components such as collagen type II alpha-1 (COL2A1) and aggrecan, which are loosely distributed in articular cartilage. Chondrocyte dysfunction has been implicated in the pathogenesis of rheumatic diseases such as osteoarthritis (OA) and rheumatoid arthritis (RA). With age, advanced glycation end products (AGEs) accumulate in all tissues and body fluids, including cartilage and synovial fluid, causing and accelerating pathological changes associated with chronic diseases such as OA. Glycolaldehyde-derived AGE (AGE3), which is toxic to a variety of cell types, have a stronger effect on cartilage compared with other AGEs. To understand the long-term effects of AGE3 on cartilage, we stimulated a human chondrosarcoma cell line (OUMS-27), which exhibits a chondrocytic phenotype, with 10 μg/ml AGE3 for 4 weeks. As a result, the expressions of COL2A1 and aggrecan were significantly downregulated in the OUMS-27 cells without inducing cell death, but the expressions of proteases that play an important role in cartilage destruction were not affected. Inhibition of the receptor for advanced glycation end products (RAGE) suppressed the AGE3-induced reduction in cartilage component production, suggesting the involvement of RAGE in the action of AGE3. en-copyright= kn-copyright= en-aut-name=HatipogluOmer Faruk en-aut-sei=Hatipoglu en-aut-mei=Omer Faruk kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishinakaTakashi en-aut-sei=Nishinaka en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YaykasliKursat Oguz en-aut-sei=Yaykasli en-aut-mei=Kursat Oguz kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoriShuji en-aut-sei=Mori en-aut-mei=Shuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WatanabeMasahiro en-aut-sei=Watanabe en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ToyomuraTakao en-aut-sei=Toyomura en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NishiboriMasahiro en-aut-sei=Nishibori en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HirohataSatoshi en-aut-sei=Hirohata en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TakahashiHideo en-aut-sei=Takahashi en-aut-mei=Hideo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=WakeHidenori en-aut-sei=Wake en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Pharmacology, Faculty of Medicine, Kindai University kn-affil= affil-num=2 en-affil=Department of Pharmacology, Faculty of Medicine, Kindai University kn-affil= affil-num=3 en-affil=Department of Internal Medicine 3-Rheumatology and Immunology, Friedrich-Alexander-University Erlangen-Nürnberg (FAU) and Universitätsklinikum Erlangen kn-affil= affil-num=4 en-affil=Department of Pharmacology, School of Pharmacy, Shujitsu University kn-affil= affil-num=5 en-affil=Department of Pharmacology, School of Pharmacy, Shujitsu University kn-affil= affil-num=6 en-affil=Department of Pharmacology, School of Pharmacy, Shujitsu University kn-affil= affil-num=7 en-affil=Department of Translational Research & Dug Development, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Medical Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Pharmacology, Faculty of Medicine, Kindai University kn-affil= affil-num=10 en-affil=Department of Pharmacology, Faculty of Medicine, Kindai University kn-affil= en-keyword=advanced glycation end product kn-keyword=advanced glycation end product en-keyword=aging kn-keyword=aging en-keyword=cartilage kn-keyword=cartilage en-keyword=collagen kn-keyword=collagen en-keyword=aggrecan kn-keyword=aggrecan END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=3 article-no= start-page=147 end-page=155 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=Immunometabolic Regulation of Innate Immunity in Systemic Lupus Erythematosus en-subtitle= kn-subtitle= en-abstract= kn-abstract=Pathogens or their components can induce long-lasting changes in the behavior of innate immune cells, a process analogous to “training” for future threats or environmental adaptation. However, such training can sometimes have unintended consequences, such as the development of autoimmunity. Systemic lupus erythematosus (SLE) is a chronic and heterogeneous autoimmune disease characterized by the production of autoantibodies and progressive organ damage. Innate immunity plays a central role in its pathogenesis, contributing through impaired clearance of apoptotic cells, excessive type I interferon production, and dysregulated formation of neutrophil extracellular traps. Recent studies have revealed that metabolites and nucleic acids derived from mitochondria, a crucial energy production site, directly regulate type I interferon and anti-inflammatory cytokine production. These insights have fueled interest in targeting metabolic pathways as a novel therapeutic approach for SLE, offering promise for improving long-term patient outcomes. en-copyright= kn-copyright= en-aut-name=WatanabeHaruki en-aut-sei=Watanabe en-aut-mei=Haruki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=systemic lupus erythematosus kn-keyword=systemic lupus erythematosus en-keyword=interferon kn-keyword=interferon en-keyword=tricarboxylic acid cycle kn-keyword=tricarboxylic acid cycle en-keyword=innate immune memory kn-keyword=innate immune memory en-keyword=trained immunity kn-keyword=trained immunity 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=20250508 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Comprehensive analysis of adverse event profile changes with pertuzumab addition to trastuzumab‐based breast cancer therapy: Disproportionality analysis using VigiBase en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aims: Pertuzumab is used in combination with trastuzumab-based therapy for HER2-positive breast cancer. However, real-world safety information on pertuzumab remains limited. This study assessed the safety of adding pertuzumab to trastuzumab-based therapy for HER2-positive breast cancer using real-world data.
Methods: VigiBase, the World Health Organization's global database of adverse events (AEs), containing reports from November 1967 to December 2023, was used. Signals for pertuzumab-associated AEs in breast cancer cases were detected using the reporting odds ratio (ROR).
Results: Signals of trastuzumab plus pertuzumab relative to trastuzumab alone were detected in gastrointestinal disorders (ROR: 1.45, 95% confidence interval: 1.26–1.67), including diarrhoea (3.49, 2.83–4.30); infections and infestations (1.54, 1.24–1.91); and skin and subcutaneous tissue disorders (ROR: 1.63, 1.40–1.90), including pruritus (1.96, 1.51–2.55) and rash (1.63, 1.20–2.23). Further, signals of trastuzumab plus docetaxel plus pertuzumab relative to those of trastuzumab plus docetaxel were detected in gastrointestinal disorders (1.63, 1.38–1.93), including nausea (1.72, 1.24–2.39) and vomiting (1.48, 1.01–2.17), and in nervous system disorders (1.50, 1.20–1.87), including paraesthesia (2.60, 1.33–5.08) and peripheral sensory neuropathy (5.94, 1.79–19.71). The frequency of AEs causing or prolonging hospitalization was increased with trastuzumab plus pertuzumab compared to that with trastuzumab alone (1.18, 1.00–1.38).
Conclusions: AE profiles after the addition of pertuzumab to trastuzumab-based therapy were comprehensively identified. The findings in this study highlight the importance of considering these AEs when selecting pertuzumab combination therapy to ensure the safety of patients with breast cancer. en-copyright=

Rarely, cystic swellings are neglected until adulthood, with only 14 cases of malignancy developing in an untreated meningomyelocele reported to date. We describe the case details of a 26-year-old Indian woman with this rare complication. Magnetic resonance imaging revealed a low-lying spinal cord with spinal dysraphism, cord herniation, and a cystic lesion. The biopsy confirmed a well-differentiated squamous cell carcinoma. Malignant transformation in an untreated myelomeningocele is rare, with chronic irritation and infection as proposed causes. Early biopsy and treatment are crucial for its management. en-copyright= kn-copyright= en-aut-name=GautamAbhishek en-aut-sei=Gautam en-aut-mei=Abhishek kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KenawadekarRahul en-aut-sei=Kenawadekar en-aut-mei=Rahul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HattiholiVirupaxi en-aut-sei=Hattiholi en-aut-mei=Virupaxi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MastePraful Suresh en-aut-sei=Maste en-aut-mei=Praful Suresh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Neurosurgery, Jawaharlal Nehru Medical College, KAHER kn-affil= affil-num=2 en-affil=Department of General Surgery, Jawaharlal Nehru Medical College, KAHER kn-affil= affil-num=3 en-affil=Department of Radiology, Jawaharlal Nehru Medical College, KAHER kn-affil= affil-num=4 en-affil=Department of Neurosurgery, Jawaharlal Nehru Medical College, KAHER kn-affil= en-keyword=squamous cell carcinoma kn-keyword=squamous cell carcinoma en-keyword=meningomyelocele kn-keyword=meningomyelocele en-keyword=occult spinal dysraphism kn-keyword=occult spinal dysraphism END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=2 article-no= start-page=109 end-page=116 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=Relationship between Personality Traits and Postpartum Depressive Symptoms in Women who Became Pregnant via Infertility Treatment en-subtitle= kn-subtitle= en-abstract= kn-abstract=The status of postpartum depression was elucidated herein with the use of the Edinburgh Postnatal Depression Scale (EPDS) in women in Shikoku, Japan who became pregnant and gave birth after undergoing infertility treatment, including assisted reproductive technology (ART). The assessment was performed during their children’s 4-month health examination. The relationships between postpartum depression and the mothers’ background factors and scores on the Big Five personality traits scale were also examined. Of the Big Five personality traits, the scores for neuroticism were significantly higher in the ART group (n=71) than in the general infertility treatment (n=118) and natural pregnancy (n=872) groups. No significant differences in EPDS scores were seen among these three groups. A logistic regression analysis showed that neuroticism was associated with an EPDS score ≧9 points, (which is suggestive of postpartum depression, ) in all groups. Moreover, although a long-standing marriage had an inhibitory effect on postpartum depression in the natural pregnancy group, no such trend was seen in the ART group, which included many women with long-standing marriages. Particularly for women who become pregnant by ART, an individualized response that pays close attention to the woman’s personality traits is needed. en-copyright= kn-copyright= en-aut-name=AwaiKyoko en-aut-sei=Awai en-aut-mei=Kyoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakatsukaMikiya en-aut-sei=Nakatsuka en-aut-mei=Mikiya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Health Sciences, Okayama University kn-affil= en-keyword=infertility treatment kn-keyword=infertility treatment en-keyword=assisted reproductive technology kn-keyword=assisted reproductive technology en-keyword=postpartum kn-keyword=postpartum en-keyword=postpartum depression kn-keyword=postpartum depression en-keyword=personality trait kn-keyword=personality trait END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=2 article-no= start-page=101 end-page=107 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=Effectiveness of Postoperative Irradiation in Patients with cN0 Early Breast Cancer Treated with Sentinel Lymph Node Surgery en-subtitle= kn-subtitle= en-abstract= kn-abstract=To evaluate the effectiveness of postoperative irradiation (POI) for patients with cN0 early breast cancer, we retrospectively analyzed the cases of 650 consecutive breast cancer patients who underwent sentinel lymph node (SLN)-guided surgery (2005-2022) at our hospital. In this cohort, 53% (278/521) of the patients who underwent breast conservative surgery (BCS) and 96% (124/129) of those treated with mastectomy did not receive POI. The patients who underwent BCS were treated with POI using opposing tangential field irradiation. A false negative (FN) SLN was retrospectively defined as a negative metastasis in SLN plus positive recurrence in the axillary lymph nodes. Recurrence was detected in 83 patients. A logistic regression analysis revealed that the nuclear grade (odds ratio [OR] 1.69), POI (OR 0.41), and postoperative hormone therapy (OR 0.40) were each significantly related to recurrence. The 26.1% (12/46) FN rate of the non-POI patients decreased to 5.8% (1/17) compared to those treated with POI. The rate of axillary recurrence was significantly lower in the POI group (0.4%) versus the non-POI group (2.7%) (p=0.0355). The rate of locoregional recurrence was also significantly lower in the POI group (2.0%) versus the non-POI group (13.4%) (p<0.0001). No significant difference was observed in the rate of distant recurrence between the POI (4.0%) and non-POI (3.3%) (p=0.831) groups. These results indicated that the postoperative opposing tangential field irradiation of conserved breast tissue inhibited recurrence in the axillary lymph nodes. en-copyright= kn-copyright= en-aut-name=IsozakiHiroshi en-aut-sei=Isozaki en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumotoSasau en-aut-sei=Matsumoto en-aut-mei=Sasau kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakamaTakehiro en-aut-sei=Takama en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IsozakiYuka en-aut-sei=Isozaki en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Surgery, Oomoto Hospital kn-affil= affil-num=2 en-affil=Department of Surgery, Oomoto Hospital kn-affil= affil-num=3 en-affil=Department of Surgery, Oomoto Hospital kn-affil= affil-num=4 en-affil=Department of Surgery, Oomoto Hospital kn-affil= en-keyword=breast cancer kn-keyword=breast cancer en-keyword=postoperative irradiation kn-keyword=postoperative irradiation en-keyword=radiation therapy kn-keyword=radiation therapy en-keyword=sentinel lymph nodes kn-keyword=sentinel lymph nodes en-keyword=recurrence kn-keyword=recurrence END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=2 article-no= start-page=93 end-page=100 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202504 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Lower Work Engagement Is Associated with Insomnia, Psychological Distress, and Neck Pain among Junior and Senior High School Teachers in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=School teachers are subject to both physical and mental health problems. We examined cross-sectional relationships between work engagement and major health outcomes among junior and senior high school teachers in Japan via a nationwide survey in 2019-2020. A total of 3,160 respondents were included in the analyses (19.9% response rate). Work engagement was assessed with the Utrecht Work Engagement Scale-9 (UWES-9), and we thus divided the teachers into quartiles according to their UWES-9 scores. Based on validated questionnaires, we assessed insomnia, psychological distress, and neck pain as health outcomes. A binomial logistic regression adjusted for age, gender, school type, teacher’s roles, involvement in club activities, division of duties, employment status, and whether they lived with family demonstrated that the teachers with lower UWES-9 scores had higher burdens of insomnia, psychological distress, and neck pain (odds ratios [95% confidence intervals] in 4th vs. 1st quartile, 2.92 (2.34-3.65), 3.70 (2.81-4.88), and 2.12 (1.68-2.68), respectively; all trend p<0.001). There were no significant differences in these associations between full-time and part-time teachers. Our findings indicate that low work engagement may contribute to physical and mental health issues among junior and senior high school teachers, thus providing insights for preventing health problems in this profession. en-copyright= kn-copyright= en-aut-name=TsuchieRina en-aut-sei=Tsuchie en-aut-mei=Rina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FukudaMari en-aut-sei=Fukuda en-aut-mei=Mari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsumuraHideki en-aut-sei=Tsumura en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KinutaMinako en-aut-sei=Kinuta en-aut-mei=Minako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HisamatsuTakashi en-aut-sei=Hisamatsu en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KandaHideyuki en-aut-sei=Kanda en-aut-mei=Hideyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Psychology, Graduate School of Technology, Industrial and Social Sciences, Tokushima University kn-affil= affil-num=4 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=work engagement kn-keyword=work engagement en-keyword=school teachers kn-keyword=school teachers en-keyword=insomnia kn-keyword=insomnia en-keyword=psychological distress kn-keyword=psychological distress en-keyword=neck pain kn-keyword=neck pain END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=2 article-no= start-page=75 end-page=80 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=Potential for Radiation Dose Reduction in Temporal Bone CT Imaging Using Photon-Counting Detector CT en-subtitle= kn-subtitle= en-abstract= kn-abstract=Temporal bone computed tomography (CT) is frequently performed for pediatric patients with ear diseases. Advances in CT technology have improved diagnostic imaging quality, but reduction of radiation exposure remains a goal. We evaluated the potential for radiation dose reduction in temporal bone CT examinations using porcine ear ossicles and a photon-counting detector CT system. Three scans of the bilateral temporal bone were performed on each of three pig cadaver heads. In each of seven successive imaging sessions, the radiation dose was reduced by an additional one-seventh of the recommended dose (RD). Two board-certified radiologists independently scored the resulting images on a scale of 1 to 5 points, where 5 represented the image quality at the RD. Images scoring ≥4.5 points were considered acceptable. Noise was assessed in a 2-cm-diameter region near the ear ossicles, and standard deviation was measured for each of the seven decrements from the RD. As the radiation dose decreased, the noise progressively increased, and visual assessment scores progressively decreased. Acceptable image scores were obtained at six-sevenths (4.9), five-sevenths (4.8), four-sevenths (4.7), and three-sevenths (4.6) of the RD. Thus, acceptable porcine temporal bone CT images were obtained with a radiation dose reduction of approximately 50%. en-copyright= kn-copyright= en-aut-name=HigakiFumiyo en-aut-sei=Higaki en-aut-mei=Fumiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MorimitsuYusuke en-aut-sei=Morimitsu en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=HwangSung Il en-aut-sei=Hwang en-aut-mei=Sung Il kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KitayamaTakahiro en-aut-sei=Kitayama en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakahashiYuka en-aut-sei=Takahashi en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=UkaMayu en-aut-sei=Uka en-aut-mei=Mayu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AkagiNoriaki en-aut-sei=Akagi en-aut-mei=Noriaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SugayaAkiko en-aut-sei=Sugaya en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=11 ORCID= en-aut-name=HirakiTakao en-aut-sei=Hiraki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Radiological Technology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Radiology, Seoul National University Bundang Hospital kn-affil= affil-num=5 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Radiological Technology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Otolaryngology-Head and Neck Surgery, Okayama University Hospital kn-affil= affil-num=10 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Radiology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Radiology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=computed tomography kn-keyword=computed tomography en-keyword=photon-counting detector computed tomography kn-keyword=photon-counting detector computed tomography en-keyword=ear ossicle kn-keyword=ear ossicle en-keyword=energy-integrating detector computed tomography kn-keyword=energy-integrating detector computed tomography END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=2 article-no= start-page=65 end-page=73 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202504 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association between the Pretreatment Body Mass Index and Anamorelin’s Efficacy in Patients with Cancer Cachexia: A Retrospective Cohort Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Anamorelin (ANAM) is used to treat cancer-associated cachexia, a syndrome involving muscle loss and anorexia. The timing of the initiation of ANAM treatment is crucial to its efficacy. Although the body mass index (BMI) is a diagnostic criterion for cancer cachexia, no studies have explored its association with ANAM efficacy. We conducted a single-center, retrospective cohort study to investigate the association between the pre-treatment BMI and ANAM efficacy in patients with cancer-associated cachexia (n=47). The ANAM treatment was considered effective if the patient’s appetite improved within 30 days of treatment initiation. We calculated a BMI cutoff value (19.5 kg/m2) and used it to divide the patients into high- and low-BMI groups. Their background, clinical laboratory values, cancer types, and treatment lines were investigated. Twenty (42.6%) had a high BMI (≥ 19.5 kg/m2) and 27 (57.4%) had a low BMI (< 19.5 kg/m2). High BMI was significantly associated with ANAM effectiveness (odds ratio 7.86, 95% confidence interval 1.99-31.00, p=0.003). Together these results indicate that it is beneficial to initiate ANAM treatment before a patient’s BMI drops below 19.5 kg/m2. Our findings will help advance cancer cachexia treatment and serve as a reference for clinicians to predict ANAM’s efficacy. en-copyright= kn-copyright= en-aut-name=MakiMasatoshi en-aut-sei=Maki en-aut-mei=Masatoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakadaRyo en-aut-sei=Takada en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IshigoTomoyuki en-aut-sei=Ishigo en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujiwaraMiki en-aut-sei=Fujiwara en-aut-mei=Miki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakahashiYoko en-aut-sei=Takahashi en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OtsukaShinya en-aut-sei=Otsuka en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TamuraKoji en-aut-sei=Tamura en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HamaokaTerutaka en-aut-sei=Hamaoka en-aut-mei=Terutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Hospital Pharmacy, NHO Fukuyama Medical Center kn-affil= affil-num=2 en-affil=Department of Hospital Pharmacy, NHO Fukuyama Medical Center kn-affil= affil-num=3 en-affil=Department of Pharmacy, Sapporo Medical University Hospital kn-affil= affil-num=4 en-affil=Department of Hospital Pharmacy, NHO Fukuyama Medical Center kn-affil= affil-num=5 en-affil=Department of Hospital Pharmacy, NHO Fukuyama Medical Center kn-affil= affil-num=6 en-affil=Department of Surgery, NHO Fukuyama Medical Center kn-affil= affil-num=7 en-affil=Department of Hospital Pharmacy, NHO Fukuyama Medical Center kn-affil= affil-num=8 en-affil=Department of Hospital Pharmacy, NHO Fukuyama Medical Center kn-affil= en-keyword=anamorelin kn-keyword=anamorelin en-keyword=cancer-associated cachexia kn-keyword=cancer-associated cachexia en-keyword=body mass index kn-keyword=body mass index en-keyword=albumin kn-keyword=albumin en-keyword=efficacy rate kn-keyword=efficacy rate END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=12633 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250412 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association of emergency intensive care unit occupancy due to brain-dead organ donors with ambulance diversion en-subtitle= kn-subtitle= en-abstract= kn-abstract=Our study aims to explore how intensive care unit (ICU) occupancy by brain-dead organ donors affects emergency ambulance diversions. In this retrospective, single-center study at an emergency ICU (EICU), brain-dead organ donors were managed until organ procurement. We classified each day between August 1, 2021, and July 31, 2023, as either an exposure day (any day with a brain-dead organ donor in the EICU from admission to organ procurement) or a control day (all other days). The study compared these days and used multiple logistic regression analysis to assess the impact of EICU occupancy by brain-dead organ donors on ambulance diversions. Over two years, 6,058 emergency patients were transported by ambulance, with 1327 admitted to the EICU, including 13 brain-dead organ donors. Brain-dead donors had longer EICU stays (17 vs. 2 days, P < 0.001). With 168 exposure and 562 control days, EICU occupancy was higher on exposure days (75% vs. 67%, P = 0.003), leading to more ambulance diversions. Logistic regression showed exposure days significantly increased ambulance diversions, with an odds ratio of 1.79 (95% CIs 1.10-2.88). This study shows that managing brain-dead organ donors in the EICU leads to longer stays and higher occupancy, resulting in more frequent ambulance diversions. These findings highlight the critical need for policies that optimize ICU resource allocation while maintaining the infrastructure necessary to support organ donation programs and ensuring continued care for brain-dead donors, who play an essential role in addressing the organ shortage crisis. en-copyright= kn-copyright= en-aut-name=YumotoTetsuya en-aut-sei=Yumoto en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=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=HongoTakashi en-aut-sei=Hongo en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=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=HisamuraMasaki en-aut-sei=Hisamura en-aut-mei=Masaki 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=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=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=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 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=Ambulance diversion kn-keyword=Ambulance diversion en-keyword=Bed occupancy kn-keyword=Bed occupancy en-keyword=Brain death kn-keyword=Brain death en-keyword=Emergency medical services kn-keyword=Emergency medical services en-keyword=Intensive care units kn-keyword=Intensive care units en-keyword=Organ donation kn-keyword=Organ donation 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=20250317 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Novel Therapeutic Algorism in Patients With Anterior Cutaneous Nerve Entrapment Syndrome en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Anterior cutaneous nerve entrapment syndrome (ACNES) is often overlooked as a cause of chronic abdominal pain. Trigger point injections (TPIs) serve as both a diagnostic and therapeutic tool. Although neurectomy is frequently chosen for patients with severe ACNES, its surgical outcomes remain unclear.
Aim: This study aims to evaluate both the short- and long-term outcomes for neurectomy and propose a novel therapeutic algorithm.
Methods: A cohort of postoperative patients presenting with ACNES between 2016 and 2023 was retrospectively evaluated. Patients received a single diagnostic TPI. When the pain subsided, an anterior neurectomy was performed using either an anterior or laparoscopic approach. Pain scores were assessed using the numeric rating scale (NRS).
Results: Among 37 patients (60% females, mean age 33.8 ± 3.4 years), 29 patients (78.4%) experienced pain recurrence following initial neurectomy. Of these, 22 patients underwent repeat neurectomies, resulting in complete remission in 15 patients and no benefit in 7 patients. Long-term outcomes showed that 62.2% achieved clinical remission (NRS = 0), whereas 8.1% reported reduced but persistent pain (NRS 1–2). Preoperative TPI effectiveness was a strong predictor of surgical success, with patients achieving post-TPI NRS (0–1) significantly more likely to attain remission (p = 0.0074). Older age was also associated with higher remission rates (p = 0.0476).
Conclusion: TPI is critical for predicting neurectomy success. These findings support the integration of preoperative TPI evaluation and tailored surgical strategies to optimize outcomes for patients with ACNES. en-copyright= kn-copyright= en-aut-name=KondoYoshitaka en-aut-sei=Kondo en-aut-mei=Yoshitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=KobayashiAmi en-aut-sei=Kobayashi en-aut-mei=Ami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ArakawaKyosuke en-aut-sei=Arakawa en-aut-mei=Kyosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MatsuokaYoshikazu en-aut-sei=Matsuoka en-aut-mei=Yoshikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MimataYudai en-aut-sei=Mimata en-aut-mei=Yudai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KakiuchiYoshihiko en-aut-sei=Kakiuchi en-aut-mei=Yoshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 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=9 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=10 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=11 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurology, Brigham and Women's Hospital, Harvard Medical School kn-affil= affil-num=4 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=anterior cutaneous nerve entrapment syndrome (ACNES) kn-keyword=anterior cutaneous nerve entrapment syndrome (ACNES) en-keyword=neurectomy kn-keyword=neurectomy en-keyword=trigger point injections (TPIs) kn-keyword=trigger point injections (TPIs) END start-ver=1.4 cd-journal=joma no-vol=33 cd-vols= no-issue=4 article-no= start-page=283 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=Cancer-related alopecia and wig acquisition: how age, sex, and treatment affect patient choices en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose This study aimed to explore the prevalence and cost of wig purchases among patients with cancer in Okayama Prefecture, Japan, and examine the relationship between wig purchases and various demographic, social, and clinical factors. The findings aim to provide insights into appearance care and support systems for patients with cancer, particularly wig subsidies.
Methods A survey was conducted between July and August 2023 among 3000 patients with cancer at 13 designated cancer care hospitals in Okayama Prefecture. Data on demographics, cancer treatment status, and wig purchase details were collected. Statistical analyses, including the Mann–Whitney U test, chi-square test, and logistic regression, were performed to identify factors significantly associated with wig purchases.
Results Among the 863 respondents, 31.4% (271 patients) reported purchasing wigs. Factors significantly associated with wig purchase included young age (odds ratio [OR] = 1.04), female sex (OR = 1.61), and current cancer treatment (OR = 1.16). No significant correlation was found between wig purchase and household income, although higher-income patients tended to purchase more expensive wigs.
Conclusion The findings suggest that younger female patients with cancer and those undergoing treatment were more likely to purchase wigs, highlighting the importance of appearance care and the need for enhanced financial support for low-income patients. en-copyright= kn-copyright= en-aut-name=KatayamaHideki en-aut-sei=Katayama en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IchiharaEiki en-aut-sei=Ichihara en-aut-mei=Eiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MoritaAyako en-aut-sei=Morita en-aut-mei=Ayako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MakimotoGo en-aut-sei=Makimoto en-aut-mei=Go kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=IshiiAyano en-aut-sei=Ishii en-aut-mei=Ayano kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TabataMasahiro en-aut-sei=Tabata en-aut-mei=Masahiro 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= affil-num=1 en-affil=Department of Palliative and Supportive Care, Okayama University Hospital kn-affil= affil-num=2 en-affil=Center for Clinical Oncology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Allergy and Respiratory Medicine , Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Allergy and Respiratory Medicine , Okayama University Hospital kn-affil= affil-num=5 en-affil=Center for Clinical Oncology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Integrated Support Center for Patients and Self-Learning , Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Palliative and Supportive Care, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= en-keyword=Cancer kn-keyword=Cancer en-keyword=Alopecia kn-keyword=Alopecia en-keyword=Wig purchases kn-keyword=Wig purchases en-keyword=Appearance care kn-keyword=Appearance care en-keyword=Patient support kn-keyword=Patient support END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=1 article-no= start-page=e70053 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250323 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association of blood carboxyhemoglobin levels with mortality and neurological outcomes in out-of-hospital cardiac arrest en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Carbon monoxide (CO), produced endogenously by heme oxygenase-1, plays a crucial role in the immune system by mitigating cellular damage under stress. However, the significance of carboxyhemoglobin (COHb) levels after out-of-hospital cardiac arrest (OHCA) is not well understood. This study aimed to explore the association between COHb levels at hospital arrival and within the first 24 h post-arrival with 30-day mortality and neurological outcomes in patients who experienced OHCA.
Methods: This single-center, retrospective study analyzed data from adult patients who experienced OHCA seen at Okayama University Hospital from 2019 to 2023. The patients were assigned to one of two study groups based on COHb levels (0.0% or >= 0.1%) upon hospital arrival. The primary outcome was 30-day mortality.
Results: Among the 560 eligible patients who experienced OHCA, 284 (50.7%) were in the COHb 0.0% group and 276 (49.3%) were in the COHb >= 0.1% group. The 30-day mortality was significantly higher in the COHb 0.0% group compared to the COHb >= 0.1% group (264 [92.9%] vs. 233 [84.4%]). Multivariable logistic regression showed that the COHb 0.0% group was associated with 30-day mortality (adjusted ORs: 2.24, 95% CIs: 1.10-4.56). Non-survivors at 30 days who were admitted to the intensive care unit had lower COHb levels at hospital arrival (0.0% vs. 0.2%) and lower mean COHb levels during the first 24 h post-arrival (0.7% vs. 0.9%) compared to survivors.
Conclusions: COHb levels of 0.0% were linked to worse outcomes in patients experiencing OHCA, warranting further research on the prognostic implications of COHb in this context. 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=NaitoHiromichi en-aut-sei=Naito en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HiraokaTomohiro en-aut-sei=Hiraoka en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MurakamiYuya en-aut-sei=Murakami en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=NojimaTsuyoshi en-aut-sei=Nojima en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AokageToshiyuki en-aut-sei=Aokage en-aut-mei=Toshiyuki 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, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Emergency, 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, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=brain injury kn-keyword=brain injury en-keyword=carbon monoxide kn-keyword=carbon monoxide en-keyword=carboxyhemoglobin kn-keyword=carboxyhemoglobin en-keyword=cardiac arrest kn-keyword=cardiac arrest en-keyword=resuscitation kn-keyword=resuscitation END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=2025 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clipping closure length is a crucial factor for delayed bleeding after endoscopic papillectomy: a retrospective multicenter cohort study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Bleeding is a serious and frequent adverse event that occurs during and after endoscopic papillectomy (EP). Previous studies have highlighted the effectiveness of preventive clipping closure of the resection site in preventing post-EP bleeding. However, the optimal length of closure remained unclear.
Objectives: We aimed to clarify the optimal clipping length at the post-EP resection site to prevent delayed bleeding.
Design: This study was a multicenter retrospective cohort study.
] Methods: We retrospectively analyzed patients who were consecutively admitted to nine high-volume centers for EP between November 2003 and October 2023. The primary outcome was the frequency of delayed bleeding based on the closure length. The optimal closure length rate of the resected site to prevent delayed bleeding was determined using a receiver operating characteristic curve. Secondary outcomes were the incidence, treatment outcomes, and risk factors for post-EP delayed bleeding.
Results: A total of 130 patients who underwent EP were analyzed. Delayed bleeding was observed in 22 (17%) patients, occurring more frequently in cases without clipping closure than in those with clipping closure (28% (13/47) vs 11% (9/83); p = 0.014). Among 83 patients who underwent clipping closure, delayed bleeding occurred more frequently with a closure length rate <65% than in those with a closure rate >= 65% (25% (5/20) vs 6% (4/63); p = 0.019). Multivariate analysis showed that a closure rate <65% was the risk factor for delayed bleeding (odds ratio, 6.3; 95% confidence interval, 1.2-33; p = 0.030) in cases with clipping.
Conclusion: Clipping closure was effective in preventing delayed bleeding, and closure length rate >= 65% of the resected site significantly reduced post-EP delayed bleeding. en-copyright=

kn-title=アパシー傾向からみた高校生の無気力の予防について ―タイムマネジメント,将来展望との関係を通して― en-subtitle= kn-subtitle= en-abstract= According to the Ministry of Education in Japan (2023), apathy is the leading cause of truancy among high school students, with the percentage of nonattendance at 40%. Therefore, this study aimed to examine the prevention of apathy among high school students. Apathy among college students has been examined as a propensity for apathy. This study presupposes that apathy among high school students is also associated with a propensity for apathy. Two hundred and nineteen high school students were participated in this research. We assumed time management (TM) and future prospects (self-fulfillment, goal-directedness, and hopefulness) would be preventive factors against apathetic tendencies for them. The study findings indicate that self-fulfillment may significantly reduce apathy, with hopefulness also contributing to reducing apathy. Additionally, the characteristics of apathy tendency, specifically lack of self, were found to be differently related to students' TM skills. In other words, the findings suggest that goal-directedness may alleviate apathy among students struggling with TM. kn-abstract= 不登校の主たる要因の1位は「無気力・不安」で40.0%を占める(文部科学省,2023)。このことは,不登校でない生徒の中にも,無気力を感じている生徒がかなりいることを示唆している。そこで本研究は,高校生の無気力とその予防について検討する。無気力は,大学生を対象にアパシー傾向として検討されてきた。そこで高校生の無気力をアパシー傾向として捉え,加えてそれを予防するものについても併せて検討した。予防法の候補として,タイムマネジメント(以下,TM)と将来展望(現在の充実感・目標指向性・希望)を想定し,高校生219名を対象に,これらの関係を検討した。分析の結果,無気力を低減するのは,現在の充実感,希望であり,特に前者が有効である可能性を示せた。一方で,アパシー傾向の自分のなさでは,TM のタイプによって異なる関係がみられた。つまり,TM が苦手な生徒では,希望よりも,目前の目標に目を向けることが無気力を低減できる可能性が示唆された。 en-copyright= kn-copyright= en-aut-name=ASADAAsuka en-aut-sei=ASADA en-aut-mei=Asuka kn-aut-name=麻田明日香 kn-aut-sei=麻田

Intraventricular Tumor Models: Case Series en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: The utility of the tubular retractor for deep-seated tumors, including intraventricular tumors, has recently been reported. However, the surgical field’s depth and narrowness can lead to blind spots, and it is crucial to prevent damage to the cortex and white matter fibers in eloquent areas. Therefore, preoperative simulation is critical for tubular retractor surgery. In this study, we investigated the benefits of threedimensional (3D)-printed intraventricular tumor models for tubular retractor surgery.
Methods: Nine patients with intraventricular central neurocytoma who underwent tubular retractor surgery at our institution between March 2013 and August 2023 were retrospectively reviewed. Fusion images and 3D-printed intraventricular tumor models were developed from preoperative computed tomography (CT) and magnetic resonance imaging (MRI). The puncture points of the tubular retractor were simulated using fusion images and 3D-printed intraventricular tumor models by 11 neurosurgeons (3 experts in brain tumors, 2 experts in areas other than brain tumors, and 6 residents). The dispersion of puncture points among 8 neurosurgeons (excluding brain tumor experts) was compared in each simulation model.
Results: These cases were categorized into two groups based on the dispersion of puncture points simulated by fusion images. Puncture point dispersion was markedly smaller in all cases when using 3D-printed intraventricular tumor models compared to simulations solely based on fusion images.
Conclusions: In intraventricular tumor surgery using a tubular retractor, 3D-printed intraventricular tumor models proved more beneficial in preoperative simulation compared to fusion images. en-copyright= kn-copyright= en-aut-name=OmaeRyo en-aut-sei=Omae en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KimuraRyu en-aut-sei=Kimura en-aut-mei=Ryu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=HarumaJun en-aut-sei=Haruma en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=FujitaJuntaro en-aut-sei=Fujita en-aut-mei=Juntaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NishigakiShohei en-aut-sei=Nishigaki en-aut-mei=Shohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IkemachiRyosuke en-aut-sei=Ikemachi en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HiranoShuichiro en-aut-sei=Hirano en-aut-mei=Shuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 ORCID= en-aut-name=FujiiKentaro en-aut-sei=Fujii en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 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=12 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=13 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= en-keyword=3D-printed model kn-keyword=3D-printed model en-keyword=Case series kn-keyword=Case series en-keyword=Intraventricular tumors kn-keyword=Intraventricular tumors en-keyword=Preoperative surgical simulation kn-keyword=Preoperative surgical simulation en-keyword=Tubular retractor kn-keyword=Tubular retractor END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=1 article-no= start-page=36 end-page=43 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=Evaluation of the temporal behavior of fulvic acid iron in Asahi River, Okayama, Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Iron is essential for biogeochemical processes in aquatic ecosystems, but its riverine concentration can be affected by environmental conditions. This study assessed weekly fulvic acid iron (FAFe) concentration at a single sampling site in Asahi River from 2022–2023 to explore the differences in the temporal scales. The objectives of this study were to evaluate the effects of physicochemical properties of the river on the concentration of FAFe, analyze the concentration of FAFe in spring, summer, autumn and winter, and assess the relationship between FAFe concentration and land use types of the watershed. The results indicated that physicochemical parameters, such as pH and surface water temperature (SWT) seemed to influence FAFe concentration (p < 0.05). Hydrological dynamics influenced FAFe concentration and transport, revealing an increasing trend during spring (p < 0.001) and summer (p = 0.05), with non-significant trends during autumn and winter (p > 0.05). FAFe exhibited a strong positive correlation with total organic carbon (TOC) (p < 0.001). Upland fields significantly influenced FAFe concentration (p < 0.01) through runoff with abundant NO3– and PO43– into the river. Thus, FAFe concentration in Asahi River was influenced by pH, SWT, TOC, hydrological regime, and agricultural runoff. en-copyright= kn-copyright= en-aut-name=YengehRohdof Lactem en-aut-sei=Yengeh en-aut-mei=Rohdof Lactem kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SomuraHiroaki en-aut-sei=Somura en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MoroizumiToshitsugu en-aut-sei=Moroizumi en-aut-mei=Toshitsugu 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= en-aut-name=MaedaMorihiro en-aut-sei=Maeda en-aut-mei=Morihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=dissolved iron kn-keyword=dissolved iron en-keyword=seasonal variation kn-keyword=seasonal variation en-keyword=dissolved organic matter kn-keyword=dissolved organic matter en-keyword=fulvic acid iron kn-keyword=fulvic acid iron END start-ver=1.4 cd-journal=joma no-vol=34 cd-vols= no-issue=1 article-no= start-page=35 end-page=40 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=Evaluation of CT Findings in Squamous and Non-Squamous Cell Carcinomas of the Maxillary Sinus en-subtitle= kn-subtitle= en-abstract= kn-abstract=The aim of the present study was to compare CT images between squamous cell carcinoma (SCC) and non-SCC found in the maxillary sinus, and to identify features that could be used to differentiate between SCC and non-SCC. Patients who visited the Faculty of Dentistry, Okayama University Hospital, between April 2007 and March 2023, underwent head and neck CT, and had tumors extending into the maxillary sinus that were diagnosed histopathologically as malignancy, were enrolled. The main seat of the mass, bony changes in the maxillary sinus wall, and extension into the surrounding area were assessed. These imaging features were evaluated according to SCC or non-SCC, and the characteristics of the two classes were assessed. Comparisons between the two groups were made using the Fisher exact probability test. There were 11 cases each of SCC and non-SCC. In 11 SCC and 7 non-SCC cases, the main seat of the mass occupied the entire maxillary sinus. The frequency of mass occupying the whole sinus was significantly higher in SCC than in non-SCC (p<0.05). Bone-thickening type disease was found only in squamous cell carcinoma 4/11 (36.4%), with there being a significant difference between SCC and non-SCC (p<0.05). Occupancy of the entire maxillary sinus by the mass and bone thickening on CT images were useful for differentiating between SCC and non-SCC arising in the maxillary sinus. en-copyright= kn-copyright= en-aut-name=AsaumiYuka en-aut-sei=Asaumi en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=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=E.

Geranylgeranylacetone (GGA) is a main component of teprenone, a gastric mucosal protectant commonly used in clinical practice. In preclinical models, GGA suppresses proinflammatory cytokines, including interleukin (IL)-1β, IL-6, and tumor necrosis factor-α (TNF-α), which are associated with GVHD as well as induces thioredoxin-1 (Trx-1), which suppresses GVHD while maintaining GVL effects. Here, we investigated whether the addition of teprenone to standard GVHD prophylaxis could reduce the cumulative incidence of severe acute GVHD (aGVHD) without attenuating GVL effects. This open-label, randomized clinical trial enrolled 40 patients (21 control and 19 teprenone group) who received allo-HSCT between May 2022 and February 2023 in our institution. Patients in the teprenone group received 50 mg of teprenone orally thrice daily for 21 days from the initiation of the conditioning regimen. The cumulative incidence of severe aGVHD by day 100 after allo-HSCT was not significantly different in the two groups (27.9 vs. 16.1%, p = 0.25). The exploratory studies revealed no obvious changes in Trx-1 levels, but the alternations from baseline in IL-1β and TNF-α levels at day 28 after allo-HSCT tended to be lower in the teprenone group. In conclusion, we could not demonstrate that teprenone significantly prevented the development of severe aGVHD. Discrepancy with preclinical model suggests that appropriate dose of teprenone may be necessary to induce the expression of antioxidant enzymes that suppress severe aGVHD.

Although there is a lack of evidence-based treatments, Kampo medicine (traditional Japanese medicine) has gained attention in Japan. At an outpatient clinic in Japan specializing in long COVID, 24% of all prescriptions were Kampo medicines, and 72% of Kampo medicine prescriptions were hochuekkito. However, there has been no prospective, quantitative study on the course of fatigue in patients with long COVID and PCC who were prescribed hochuekkito. The aim of this study was to clarify the course of fatigue in those patients. Methods: This study included patients aged 18 years or older with general fatigue who visited the long COVID specialized outpatient clinic at Okayama University Hospital and consented to participate after being prescribed hochuekkito. We reviewed the backgrounds of the patients, and we evaluated the patients' fatigue assessment scale in person or online. Results: Twenty patients were enrolled in this study from September to December in 2023. The average age of the patients was 42.9 years (SD: 15.8 years) and 12 patients (60%) were female. After hochuekkito administration, the fatigue assessment scale score decreased from 35.9 (SD: 5.9) at the initial visit to 31.2 (SD: 9.4) after 8 weeks, indicating a trend for improvement in fatigue (difference: 4.7; 95% CI: 0.5-8.9). Conclusions: A trend for improvement in fatigue was observed in patients with long COVID and PCC who were prescribed hochuekkito, indicating a potential benefit of hochuekkito for general fatigue in such patients. General fatigue in patients with long COVID or PCC can be classified as post-infectious fatigue syndrome and is considered a condition of qi deficiency in Kampo medicine, for which hochuekkito is appropriately indicated. en-copyright= kn-copyright= en-aut-name=TokumasuKazuki en-aut-sei=Tokumasu en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsukiNobuyoshi en-aut-sei=Matsuki en-aut-mei=Nobuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OtsukaYuki en-aut-sei=Otsuka en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakamotoYoko en-aut-sei=Sakamoto en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UedaKeigo en-aut-sei=Ueda en-aut-mei=Keigo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MatsudaYui en-aut-sei=Matsuda en-aut-mei=Yui kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SakuradaYasue en-aut-sei=Sakurada en-aut-mei=Yasue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HondaHiroyuki en-aut-sei=Honda en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakanoYasuhiro en-aut-sei=Nakano en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HasegawaToru en-aut-sei=Hasegawa en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TakaseRyosuke en-aut-sei=Takase en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=OmuraDaisuke en-aut-sei=Omura en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 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=13 ORCID= affil-num=1 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=11 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=12 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=13 en-affil=Department of General Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=fatigue assessment scale (FAS) kn-keyword=fatigue assessment scale (FAS) en-keyword= general fatigue kn-keyword= general fatigue en-keyword= hochuekkito kn-keyword= hochuekkito en-keyword= kampo medicine kn-keyword= kampo medicine en-keyword= long COVID kn-keyword= long COVID en-keyword= post-COVID-19 condition kn-keyword= post-COVID-19 condition END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=1 article-no= start-page=ra.2023-0019 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=2025 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Non-Sinus-Type Dural Arteriovenous Fistula at the Foramen Magnum: A Review of the Literature en-subtitle= kn-subtitle= en-abstract= kn-abstract=Dural arteriovenous fistula (dAVF) of the foramen magnum (FM) region is rare. Moreover, the terminology of dAVF is very confusing in this region. In the narrow sense, the FM dAVF is the non-sinus-type dAVF with direct venous reflux to the medulla oblongata or spinal cord via the bridging veins (BVs) of the FM. Previous literature was systematically reviewed to investigate the clinical characteristics, angioarchitecture, and effective treatment of the FM dAVF. From the literature review, almost all the feeders of FM dAVF were dural branches. Spinal pial arteries were rarely involved as the feeder. All lesions had venous reflux to the medulla oblongata via medullary BVs. The FM dAVF is characterized by a significant male predominance and a high incidence of aggressive symptoms. The most common symptom is congestive myelopathy, followed by hemorrhage. The FM dAVF differs from the craniocervical junction (CCJ) arteriovenous fistula (AVF) and is similar to the thoracolumbar spinal dAVF. Direct surgery for the FM dAVF is effective and safe. Endovascular treatment for the FM dAVF may be more effective and has lower complication rates than that for the CCJ AVF. en-copyright= kn-copyright= en-aut-name=HiramatsuMasafumi en-aut-sei=Hiramatsu en-aut-mei=Masafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OzakiTomohiko en-aut-sei=Ozaki en-aut-mei=Tomohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AokiRie en-aut-sei=Aoki en-aut-mei=Rie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OdaShinri en-aut-sei=Oda en-aut-mei=Shinri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HarumaJun en-aut-sei=Haruma en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HishikawaTomohito en-aut-sei=Hishikawa en-aut-mei=Tomohito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SugiuKenji en-aut-sei=Sugiu en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurosurgery, National Hospital Organization Osaka National Hospital kn-affil= affil-num=3 en-affil=Department of Neurosurgery, Tokai University Hachioji Hospital kn-affil= affil-num=4 en-affil=Department of Neurosurgery, Tokai University Hachioji Hospital kn-affil= affil-num=5 en-affil=Department of Neurological Surgery, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Neurological Surgery, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Neurological Surgery, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Neurological Surgery, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=dural arteriovenous fistula kn-keyword=dural arteriovenous fistula en-keyword=foramen magnum kn-keyword=foramen magnum en-keyword=bridging vein kn-keyword=bridging vein en-keyword=treatment kn-keyword=treatment END start-ver=1.4 cd-journal=joma no-vol=64 cd-vols= no-issue=2 article-no= start-page=97 end-page=106 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=2024 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Atypical lymphoplasmacytic and immunoblastic proliferation: A Systematic Review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Atypical lymphoplasmacytic and immunoblastic proliferation (ALPIBP) was first reported in 1984 as characteristic histological findings in lymph nodes associated with autoimmune diseases, but it has not been clearly defined to date. To summarize the histological characteristics and clinical diagnoses associated with ALPIBP, we searched MEDLINE and EMBASE for all peer-reviewed articles using keywords including “atypical lymphoplasmacytic and immunoblastic lymphadenopathy” from their inception to December 27, 2023. We also summarized the courses of three cases with a pathological diagnosis of ALPIBP. Nine articles with 52 cases were included. Among the total of 55 cases, including the three from our institution, the median age of the cases was 63.5 years with a female predominance (69.5%). Lymphadenopathy was generalized in 65.6% and regional in 34.4% of cases. RA (24.4%), SLE (24.4%), and autoimmune hemolytic anemia (20.0%), were common clinical diagnoses. A combination of cytotoxic chemotherapy was used in 15.6% of cases due to the suspicion of malignancy. Nodal T-follicular helper cell lymphoma, angioimmunoblastic type, methotrexate-associated lymphoproliferative disorders, and IgG4-related diseases were listed as important diseases that need to be pathologically differentiated from ALPIBP. This review summarizes the current understanding of the characteristics of ALPIBP. Given that underrecognition of ALPIBP could lead to overdiagnosis of hematological malignancy and unnecessary treatment, increased awareness of the condition in pathologists and clinicians is crucial. en-copyright= kn-copyright= en-aut-name=NishimuraMidori Filiz en-aut-sei=Nishimura en-aut-mei=Midori Filiz kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakahashiToshiaki en-aut-sei=Takahashi en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakaokaKensuke en-aut-sei=Takaoka en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MacapagalSharina en-aut-sei=Macapagal en-aut-mei=Sharina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WannaphutChalothorn en-aut-sei=Wannaphut en-aut-mei=Chalothorn kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NishikoriAsami en-aut-sei=Nishikori en-aut-mei=Asami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TodaHiroko en-aut-sei=Toda en-aut-mei=Hiroko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NishimuraYoshito en-aut-sei=Nishimura en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SatoYasuharu en-aut-sei=Sato en-aut-mei=Yasuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Molecular Hematopathology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=2 en-affil=Department of Medicine, John A.

We describe a case of an IOAVF featuring a direct shunt between the accessory meningeal artery and the superior ophthalmic artery. A 55-year-old woman presented with a 1-month history of visual impairment in her right eye, and magnetic resonance imaging (MRI) revealed optic neuritis-like findings. Steroid pulse therapy temporarily resolved visual impairment. However, 1 month later, she experienced decreased visual acuity, ocular conjunctival hyperemia, edema, and a pulsatile murmur. Contrast-enhanced MRI and digital subtraction angiography revealed compression optic neuropathy due to an IOAVF. Following successful treatment with transarterial embolization, her symptoms disappeared. en-copyright= kn-copyright= en-aut-name=MinakawaShun en-aut-sei=Minakawa en-aut-mei=Shun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HiranoMasayuki en-aut-sei=Hirano en-aut-mei=Masayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakahashiKazuya en-aut-sei=Takahashi en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ImamuraYuta en-aut-sei=Imamura en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WatanabeTakashi en-aut-sei=Watanabe en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Ophthalmology, Japanese Red Cross Society Himeji Hospital kn-affil= affil-num=2 en-affil=Department of Ophthalmology, Japanese Red Cross Society Himeji Hospital kn-affil= affil-num=3 en-affil=Department of Neurosurgery, Japanese Red Cross Society Himeji Hospital kn-affil= affil-num=4 en-affil=Department of Ophthalmology, Japanese Red Cross Society Himeji Hospital kn-affil= affil-num=5 en-affil=Department of Ophthalmology, Japanese Red Cross Society Himeji Hospital kn-affil= en-keyword=intraorbital arteriovenous fistula kn-keyword=intraorbital arteriovenous fistula en-keyword=compressive optic neuropathy kn-keyword=compressive optic neuropathy en-keyword=accessory meningeal artery kn-keyword=accessory meningeal artery en-keyword=superior ophthalmic vein kn-keyword=superior ophthalmic vein END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=1 article-no= start-page=9 end-page=19 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202502 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Gastrectomy Causes an Imbalance in the Trunk Muscles en-subtitle= kn-subtitle= en-abstract= kn-abstract=Muscle loss negatively affects gastrectomy prognosis. However, muscle loss is recognized as a systemic change, and individual muscle function is often overlooked. We investigated changes in the muscle volume of individual muscles after gastrectomy to identify clues for prognostic factors and optimal rehabilitation programs. Patients who underwent R0 gastrectomy for Stage I gastric cancer at our hospital from 2015 to 2021 were retrospectively selected to minimize the effects of malignancy and chemotherapy. Trunk muscle volume was measured by computed tomography to analyze body composition changes. Statistical analysis was performed to identify risk factors related to body composition changes. We compared the preoperative and 6-month postoperative conditions of 59 patients after gastrectomy. There was no difference in the psoas major muscle, a conventional surrogate marker of sarcopenia. There were significant decreases in the erector spinae (p=0.01) and lateral abdominal (p=0.01) muscles, and a significant increase in the rectus abdominis muscle (p=0.02). No significant correlation was found between these muscle changes and nutritional status. Body composition imbalance may serve as a new indicator of the general condition of patients after gastrectomy. Rehabilitation to correct this imbalance may improve prognosis after gastrectomy. en-copyright= kn-copyright= en-aut-name=IkeyaNanami en-aut-sei=Ikeya en-aut-mei=Nanami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkitaAtsushi en-aut-sei=Okita en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HashidaShinsuke en-aut-sei=Hashida en-aut-mei=Shinsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamamotoSumiharu en-aut-sei=Yamamoto en-aut-mei=Sumiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IkedaHirokuni en-aut-sei=Ikeda en-aut-mei=Hirokuni kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TsukudaKazunori en-aut-sei=Tsukuda en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= affil-num=1 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Surgery, Okayama City Hospital kn-affil= affil-num=3 en-affil=Department of Surgery, Okayama City Hospital kn-affil= affil-num=4 en-affil=Department of Surgery, Okayama City Hospital kn-affil= affil-num=5 en-affil=Department of Surgery, Okayama City Hospital kn-affil= affil-num=6 en-affil=Department of Surgery, Okayama City Hospital kn-affil= affil-num=7 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=sarcopenia kn-keyword=sarcopenia en-keyword=skeletal muscle kn-keyword=skeletal muscle en-keyword=gastric cancer kn-keyword=gastric cancer en-keyword=gastrectomy kn-keyword=gastrectomy en-keyword=erector spinae muscle kn-keyword=erector spinae muscle END start-ver=1.4 cd-journal=joma no-vol=121 cd-vols= no-issue=35 article-no= start-page=e2320189121 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240821 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Somatic mutations in tumor-infiltrating lymphocytes impact on antitumor immunity en-subtitle= kn-subtitle= en-abstract= kn-abstract=Immune checkpoint inhibitors (ICIs) exert clinical efficacy against various types of cancers by reinvigorating exhausted CD8+ T cells that can expand and directly attack cancer cells (cancer-specific T cells) among tumor-infiltrating lymphocytes (TILs). Although some reports have identified somatic mutations in TILs, their effect on antitumor immunity remains unclear. In this study, we successfully established 18 cancer-specific T cell clones, which have an exhaustion phenotype, from the TILs of four patients with melanoma. We conducted whole-genome sequencing for these T cell clones and identified various somatic mutations in them with high clonality. Among the somatic mutations, an SH2D2A loss-of-function frameshift mutation and TNFAIP3 deletion could activate T cell effector functions in vitro. Furthermore, we generated CD8+ T cell–specific Tnfaip3 knockout mice and showed that Tnfaip3 function loss in CD8+ T cell increased antitumor immunity, leading to remarkable response to PD-1 blockade in vivo. In addition, we analyzed bulk CD3+ T cells from TILs in additional 12 patients and identified an SH2D2A mutation in one patient through amplicon sequencing. These findings suggest that somatic mutations in TILs can affect antitumor immunity and suggest unique biomarkers and therapeutic targets. en-copyright= kn-copyright= en-aut-name=MukoharaFumiaki

pilot study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: Endoscopic ultrasonography (EUS)-guided radiofrequency ablation has recently been introduced as one of the management strategies for small pancreatic neuroendocrine neoplasms (PNENs). However, prospective data on its safety and efficacy remain limited.
Methods: This prospective pilot study was conducted at Okayama University Hospital from May 2023 to December 2024. Patients with grade 1 PNENs <= 15 mm, confirmed by EUS-guided fine-needle aspiration, were included. The primary endpoint was safety (adverse events [AEs] evaluated according to the 2010 guidelines of the American Society for Gastrointestinal Endoscopy. Severe AEs were defined as moderate or higher in American Society for Gastrointestinal Endoscopy grading and grade >= 3. Secondary endpoints included efficacy (complete response on contrast-enhanced computed tomography at 1 and 6 months), treatment details, device failure, diabetes mellitus exacerbation, and overall survival at 6 months.
Results: Five patients with non-functional PNENs (median age: 64 years; median tumor size: 10 mm) were treated. AEs occurred in two patients (40%, 2/5), although none was severe. Both patients developed asymptomatic pseudocysts, one experienced mild pancreatitis, and both resolved with conservative treatment. The complete response rates on contrast-enhanced computed tomography at one and 6 months were 100%. The median procedure time was 16 min without any device failure, and the median hospitalization was 5 days. None of the patients developed new-onset or worsening diabetes mellitus. The 6-month overall survival rate was 100%.
Conclusion: EUS-guided radiofrequency ablation demonstrated a high complete response rate with no severe AEs in this pilot study, suggesting a minimally invasive option for small, low-grade PNENs (jRCTs062230014). en-copyright= kn-copyright= en-aut-name=MatsumotoKazuyuki en-aut-sei=Matsumoto en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID=

kn-abstract=Background: We developed a virtual reality (VR) education system and evaluated its clinical utility for promoting hand hygiene practices.
Methods: This prospective, 2-week, randomized controlled study conducted at Okayama University Hospital, Japan, from November 2023 to January 2024, involved 22 participants (18 medical students and 4 residents). A fully immersive 360° VR system (VIVE Pro Eye) using a head-mounted display and sensing gloves was used to develop 3 health care tasks in a virtual patient room—Environmental Cleaning, Gauze Exchange, and Urine Collection. After monitoring all participants' baseline usage data of portable hand-rubbing alcohol in the first week, we randomly assigned them into 1:1 groups (VR training and video lecture groups). The primary outcome was differences in hand-rubbed alcohol use before and after intervention.
Results: Before the intervention, alcohol use did not significantly differ between both groups. After the intervention, a significant increase in alcohol use was observed in the VR training group (median: 8.2 g vs 16.2 g; P = .019) but not in the video lecture group.
Conclusions: Our immersive 360° VR education system enhanced hand hygiene practices. Infection prevention and control practitioners and digital technology experts must collaborate to advance the development of superior educational devices and content. en-copyright= kn-copyright= en-aut-name=IzumiMahiro en-aut-sei=Izumi en-aut-mei=Mahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OtsukaYuki en-aut-sei=Otsuka en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SoejimaYoshiaki en-aut-sei=Soejima en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FukushimaShinnosuke en-aut-sei=Fukushima en-aut-mei=Shinnosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShibataMitsunobu en-aut-sei=Shibata en-aut-mei=Mitsunobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HirotaSatoshi en-aut-sei=Hirota en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KoyamaToshihiro en-aut-sei=Koyama en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= en-aut-name=GofukuAkio en-aut-sei=Gofuku en-aut-mei=Akio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Quality Assurance Center, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=6 en-affil=Quality Assurance Center, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=7 en-affil=Quality Assurance Center, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=8 en-affil=Department of Health Data Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Quality Assurance Center, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=Infection prevention and control kn-keyword=Infection prevention and control en-keyword=Medical-engineering collaboration kn-keyword=Medical-engineering collaboration END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue=2 article-no= start-page=80 end-page=90 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230627 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Antioxidant action of xanthine oxidase inhibitor febuxostat protects the liver and blood vasculature in SHRSP5/Dmcr rats en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Xanthine oxidase (XO) generates reactive oxygen species during uric acid production. Therefore, XO inhibitors, which suppress oxidative stress, may effectively treat non-alcoholic steatohepatitis (NASH) and atherosclerosis via uric acid reduction. In this study, we examined the antioxidant effect of the XO inhibitor febuxostat on NASH and atherosclerosis in stroke-prone spontaneously hypertensive 5 (SHRSP5/Dmcr) rats.
Methods: SHRSP5/Dmcr rats were divided into three groups: SHRSP5/Dmcr + high-fat and high-cholesterol (HFC) diet [control group, n = 5], SHRSP5/Dmcr + HFC diet + 10% fructose (40 ml/day) [fructose group, n = 5], and SHRSP5/Dmcr + HFC diet + 10% fructose (40 ml/day) + febuxostat (1.0 mg/kg/day) [febuxostat group, n = 5]. Glucose and insulin resistance, blood biochemistry, histopathological staining, endothelial function, and oxidative stress markers were evaluated.
Results: Febuxostat reduced the plasma uric acid levels. Oxidative stress-related genes were downregulated, whereas antioxidant factor-related genes were upregulated in the febuxostat group compared with those in the fructose group. Febuxostat also ameliorated inflammation, fibrosis, and lipid accumulation in the liver. Mesenteric lipid deposition decreased in the arteries, and aortic endothelial function improved in the febuxostat group.
Conclusions: Overall, the XO inhibitor febuxostat exerted protective effects against NASH and atherosclerosis in SHRSP5/Dmcr rats. en-copyright= kn-copyright= en-aut-name=KakimotoMai en-aut-sei=Kakimoto en-aut-mei=Mai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiiMoe en-aut-sei=Fujii en-aut-mei=Moe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SatoIkumi en-aut-sei=Sato en-aut-mei=Ikumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HonmaKoki en-aut-sei=Honma en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakayamaHinako en-aut-sei=Nakayama en-aut-mei=Hinako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KiriharaSora en-aut-sei=Kirihara en-aut-mei=Sora kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FukuokaTaketo en-aut-sei=Fukuoka en-aut-mei=Taketo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=RanShang en-aut-sei=Ran en-aut-mei=Shang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HirohataSatoshi en-aut-sei=Hirohata en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KitamoriKazuya en-aut-sei=Kitamori en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YamamotoShusei en-aut-sei=Yamamoto en-aut-mei=Shusei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=WatanabeShogo en-aut-sei=Watanabe en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Okayama University, Graduate School of Health Sciences, Department of Medical Technology kn-affil= affil-num=2 en-affil=Okayama University, Graduate School of Health Sciences, Department of Medical Technology kn-affil= affil-num=3 en-affil=Okayama University, Graduate School of Health Sciences, Department of Medical Technology kn-affil= affil-num=4 en-affil=Okayama University, Graduate School of Health Sciences, Department of Medical Technology kn-affil= affil-num=5 en-affil=Okayama University, Graduate School of Health Sciences, Department of Medical Technology kn-affil= affil-num=6 en-affil=Okayama University, Graduate School of Health Sciences, Department of Medical Technology kn-affil= affil-num=7 en-affil=Okayama University, Faculty of Health Sciences, Department of Medical Technology kn-affil= affil-num=8 en-affil=Okayama University, Graduate School of Health Sciences, Department of Medical Technology kn-affil= affil-num=9 en-affil=Okayama University, Academic Field of Health Science kn-affil= affil-num=10 en-affil=Kinjo Gakuin University, College of Human Life and Environment kn-affil= affil-num=11 en-affil=Okayama University, Graduate School of Health Sciences, Department of Medical Technology kn-affil= affil-num=12 en-affil=Okayama University, Academic Field of Health Science kn-affil= en-keyword=Anti-inflammatory kn-keyword=Anti-inflammatory en-keyword=Atherosclerosis kn-keyword=Atherosclerosis en-keyword=Febuxostat kn-keyword=Febuxostat en-keyword=Non-alcoholic steatohepatitis (NASH) kn-keyword=Non-alcoholic steatohepatitis (NASH) en-keyword=Oxidative stress kn-keyword=Oxidative stress en-keyword=Uric acid kn-keyword=Uric acid END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue=3 article-no= start-page=98 end-page=101 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230727 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Case of a Transwoman with Colorectal Cancer after Flap Vaginoplasty en-subtitle= kn-subtitle= en-abstract= kn-abstract=Vaginoplasty is a gender-affirming surgery (GAS) for transwomen that laid its foundation in the 1950s and continues to be widely practiced worldwide. We present here a case of a 70-year-old transwoman who underwent lower anterior resection for rectal cancer 12 years after vaginoplasty. The preoperative diagnosis was rectal cancer (Rb-Ra, type 2, cT2N0M0, stage 1). All imaging studies showed a cord-like structure between the prostate and the anterior wall of the rectum, which was thought to be the neovagina. Careful dissection of the anterior rectal wall was required because the distance between the neovagina and the rectum was only 1.5 mm. The role of hormonal therapy and GAS in cancer development in transwomen is unclear. It is important to have regular check-ups for malignancies in patients who have undergone GAS, and if surgical procedures are needed, they should be treated by physicians who are familiar with the procedure. en-copyright= kn-copyright= en-aut-name=WatanabeShiho en-aut-sei=Watanabe en-aut-mei=Shiho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TeraishiFuminori en-aut-sei=Teraishi en-aut-mei=Fuminori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujimotoSari en-aut-sei=Fujimoto en-aut-mei=Sari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WatanabeToshiyuki en-aut-sei=Watanabe en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakedaSho en-aut-sei=Takeda en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NaritaShuhei en-aut-sei=Narita en-aut-mei=Shuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YamashitaKoya en-aut-sei=Yamashita en-aut-mei=Koya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=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=NambaYuzaburo en-aut-sei=Namba en-aut-mei=Yuzaburo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KimataYoshihiro en-aut-sei=Kimata en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Plastic and Reconstructive Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Minimally Invasive Therapy Center, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Plastic and Reconstructive Surgery, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Plastic and Reconstructive Surgery, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Gender Center, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Plastic and Reconstructive Surgery, Okayama University Hospital kn-affil= en-keyword=vaginoplasty kn-keyword=vaginoplasty en-keyword=gender-affirming surgery kn-keyword=gender-affirming surgery en-keyword=transwomen kn-keyword=transwomen en-keyword=rectal cancer kn-keyword=rectal cancer END start-ver=1.4 cd-journal=joma no-vol=51 cd-vols= no-issue=4 article-no= start-page=781 end-page=794 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230703 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Does International Environmental Certification Change Local Production and Trade Practices? A Case Study of Shrimp Farming in Southern Vietnam en-subtitle= kn-subtitle= en-abstract= kn-abstract=Studies on international environmental certification (IEC) have primarily focused on how certification can sustainably “upgrade” local production and trading practices. However, not many studies view this market-based governance process from the perspective of local practices and location-specific factors. This study therefore examines how the upstream of the local supply chain influenced global interventions through the case of certification for shrimp farming in the mangroves of southern Vietnam. To clarify various aspects of these interactions, semi-structured interviews were conducted with the provincial government, NGOs, a trading company, shrimp farmers, and middlemen. The results revealed that IEC did not affect local production practices and only partially influenced trade practices. The implementation of IEC was thus at the mercy of the robustness of local society, which was attributed to unique agroecology, production systems, and upstream customary economic practices. en-copyright= kn-copyright= en-aut-name=WatanabeHiroki en-aut-sei=Watanabe en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UbukataFumikazu en-aut-sei=Ubukata en-aut-mei=Fumikazu 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=Institute of Academic and Research, Okayama University kn-affil= en-keyword=International environmental certification kn-keyword=International environmental certification en-keyword=Shrimp farming kn-keyword=Shrimp farming en-keyword=Upstream of supply chain kn-keyword=Upstream of supply chain en-keyword=Local robustness kn-keyword=Local robustness en-keyword=Vietnam kn-keyword=Vietnam END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=1 article-no= start-page=74 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241215 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Case series showing the safety and changes in lipid profiles of hemodialysis patients with hypertriglyceridemia after pemafibrate administration en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Cardiovascular disease is a major cause of morbidity and mortality in patients with chronic kidney disease and end-stage renal disease (ESRD). Dyslipidemia is a key focus of cardiovascular therapy and is characterized by hypertriglyceridemia mainly caused by lipoprotein lipase-mediated metabolism of ApoC-III in patients with ESRD. Pemafbrate, a selective peroxisome proliferator-activated receptor alpha modulator, can be used regardless of renal function and inhibit ApoC-III expression in the liver.
Case presentation We reported the cases of four patients on hemodialysis who met at least 175 mg/dL of triglycerides on the consecutive three tests between September 2022 and November 2022 and took 0.1 mg pemafbrate twice a day from November 2022 to May 2023. They experienced no adverse events after pemafbrate treatment. Pemafbrate signifcantly reduced triglyceride (TG) (302±72 to 140±50 mg/dL, p=0.048), total cholesterol (187±34 to 156±48 mg/dL, p=0.025), and Apo C-III (15.9±8.2 to 12.6±7.1, p=0.030) levels. Apo A-II levels signifcantly increased after treatment (27.0±6.1 to 37.1±5.8, p=0.041).
Conclusions Pemafbrate decreased TG, total cholesterol, and Apo-CIII and increased Apo A-II without adverse events. Further study is needed to examine the favorable efects of pemafbrate on the risk of CVD. en-copyright= kn-copyright= en-aut-name=OkadaRino en-aut-sei=Okada en-aut-mei=Rino kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OnishiYasuhiro en-aut-sei=Onishi en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KobayashiNaoya en-aut-sei=Kobayashi en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IshiharaHiroyuki en-aut-sei=Ishihara en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YokoyamaTomohisa en-aut-sei=Yokoyama en-aut-mei=Tomohisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MifuneTomoyo en-aut-sei=Mifune en-aut-mei=Tomoyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SakurabuYoshimasa en-aut-sei=Sakurabu en-aut-mei=Yoshimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NojimaIchiro en-aut-sei=Nojima en-aut-mei=Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MorinagaHiroshi en-aut-sei=Morinaga en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 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=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=Okayama Saidaiji Hospital kn-affil= affil-num=4 en-affil=Okayama Saidaiji Hospital kn-affil= affil-num=5 en-affil=Okayama Saidaiji Hospital kn-affil= affil-num=6 en-affil=Okayama Saidaiji Hospital kn-affil= affil-num=7 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Hemodialysis kn-keyword=Hemodialysis en-keyword=Dyslipidemia kn-keyword=Dyslipidemia en-keyword=Apolipoprotein kn-keyword=Apolipoprotein en-keyword=Pemafibrate kn-keyword=Pemafibrate END start-ver=1.4 cd-journal=joma no-vol=45 cd-vols= no-issue=1 article-no= start-page=e12512 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250109 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Nicotine dependence based on the tobacco dependence screener among heated tobacco products users in Japan, 2022-2023: The JASTIS study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Heated tobacco products (HTPs) are nicotine-containing products similar to cigarettes and are widely used in Japan. However, there has been insufficient research on nicotine dependence associated with HTP use. This study investigated the association of the types of individuals who smoked with the prevalence of nicotine dependence. We utilized data from the Japan Survey on Tobacco and Health (JASTIS). A total of 7969 participants who currently smokes was selected from the 2022 and 2023 survey respondents for the analysis. Nicotine dependence was defined as a score of 5 or higher on the Tobacco Dependence Screener (TDS). The prevalence of nicotine dependence was 43.0% (3473/8077) among all participants who smoked, 42.9% (1479/3447) among those who used cigarettes, 44.2% (760/1720) among those who used two products, and 43.0% (1206/2802) among those who used HTPs. The prevalence of nicotine dependence was statistically higher in the participants who used two products than in cigarettes (odds ratio [OR], 1.17; 95% confidence interval [CI], 1.04-1.33). When classified by temperature, participants who used of two products (high-temp and low-temp) and those using participants who used HTPs (high-temp) had higher ORs for prevalent nicotine dependence (OR, 1.31 [95% CI, 1.14-1.51]) and (OR, 1.12 [95% CI, 1.00-1.25], respectively) compared to participants who used cigarettes. Additionally, the ORs for prevalent nicotine dependence increased with the number of tobacco sticks smoked per day. These results suggest that HTP use, particularly high-temperature HTPs use, and a higher number of tobacco sticks smoked is associated with nicotine dependence. en-copyright= kn-copyright= en-aut-name=KitajimaTakuma en-aut-sei=Kitajima en-aut-mei=Takuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HisamatsuTakashi en-aut-sei=Hisamatsu en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KandaHideyuki en-aut-sei=Kanda en-aut-mei=Hideyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TabuchiTakahiro en-aut-sei=Tabuchi en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Division of Epidemiology, Department of Health Informatics and Public Health, School of Public Health, Tohoku University Graduate School of Medicine kn-affil= en-keyword=cross-sectional survey kn-keyword=cross-sectional survey en-keyword= heated tobacco products kn-keyword= heated tobacco products en-keyword= logistic regression kn-keyword= logistic regression en-keyword= nicotine dependence kn-keyword= nicotine dependence en-keyword= tobacco dependence screener kn-keyword= tobacco dependence screener END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=1 article-no= start-page=e70031 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241226 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Characteristics and outcomes of subarachnoid hemorrhage from vertebral artery dissection: A comparative study with other non-traumatic etiologies en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aim: Vertebral artery dissection (VAD) is a rare cause of non-traumatic subarachnoid hemorrhage (SAH) with significant clinical implications. This study compared the clinical characteristics and outcomes of SAH from intracranial VAD rupture to those from other etiologies, primarily aneurysmal rupture.
Methods: This single-center retrospective cohort study at Okayama University Hospital included patients with non-traumatic SAH diagnosed between 2019 and 2023. Patients were categorized into "VAD rupture" and "other etiologies" groups. The main outcome was clinical presentation and symptoms. Additional outcomes included ICU mortality, in-hospital mortality, and unfavorable outcomes at discharge and 6 months, defined as a modified Rankin Scale score of 3-6.
Results: A total of 66 patients were included, with 14 in the VAD rupture group and 52 in the other etiologies group. The VAD rupture group was younger (median age 49 vs. 64 years, p = 0.003) and had a higher incidence of out-of-hospital cardiac arrest (42.9% vs. 9.6%, p = 0.011). Preceding headache was more common in the VAD rupture group (78.6% vs. 11.5%, p < 0.001), with a median duration of 36 h before presentation. ICU and in-hospital mortality was higher in the VAD rupture group (both 50.0% vs. 19.3%, p = 0.019). No significant differences were found in unfavorable neurological outcomes at hospital discharge and 6 months.
Conclusions: VAD-related SAH often presents with prodromal headaches, severe symptoms like out-of-hospital cardiac arrest, and higher ICU and in-hospital mortality than other SAH causes, though long-term outcomes are similar. Larger, prospective studies are needed to refine interventions. en-copyright= kn-copyright= en-aut-name=OshitaShu en-aut-sei=Oshita en-aut-mei=Shu 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=JinnoShunta en-aut-sei=Jinno en-aut-mei=Shunta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsuoIppei en-aut-sei=Matsuo en-aut-mei=Ippei 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=NaitoHiromichi en-aut-sei=Naito en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HiramatsuMasafumi en-aut-sei=Hiramatsu en-aut-mei=Masafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HarumaJun en-aut-sei=Haruma en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SugiuKenji en-aut-sei=Sugiu en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 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=11 ORCID= affil-num=1 en-affil=Okayama University Medical School kn-affil= affil-num=2 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Neurological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Neurological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Neurological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Neurological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=11 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=headache kn-keyword=headache en-keyword=intracranial aneurysm kn-keyword=intracranial aneurysm en-keyword=prodromal symptoms kn-keyword=prodromal symptoms en-keyword=subarachnoid hemorrhage kn-keyword=subarachnoid hemorrhage en-keyword=vertebral artery dissection kn-keyword=vertebral artery dissection END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=23 article-no= start-page=7078 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241123 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinical Characteristics of Persistent Hypophosphatasemia Uncovered in Adult Patients: A Retrospective Study at a Japanese Tertiary Hospital en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Hypophosphatasemia is often overlooked despite its potential to indicate underlying pathologies. The aim of this study was to determine the prevalence of persistent hypophosphatasemia in a large, urban, multi-specialty hospital population and characterize the clinical and laboratory findings in adult patients with this condition. Methods: In this retrospective observational study, the results of 424,434 alkaline phosphatase (ALP) tests in 50,136 patients aged >= 18 years that were performed at Okayama University Hospital between July 2020 and October 2023 were analyzed. Persistent hypophosphatasemia was defined as consistently low ALP levels (<= 40 IU/L) for 28 days with a minimum recorded level of <= 35 IU/L. Results: Persistent hypophosphatasemia was detected in 273 patients (0.54% of the tested patients), and the patients with persistent hypophosphatasemia included a higher proportion of females (72.5% vs. 52.9% in the people without persistent hypophosphatasemia; chi-squared test, p < 0.01) and had a younger median age (51 years vs. 63 years; Mann-Whitney U test, p < 0.01) than those in the overall tested population. The common causes of persistent hypophosphatasemia were cancer (30%), glucocorticoid use (21%), and immunosuppressants (16%). Notably, 38 patients (14%) had no apparent cause for low ALP values. These patients were categorized on the basis of their clinical characteristics, with some patients presenting symptoms potentially related to adult hypophosphatasia. Conclusions: This study provides prevalence and insights into the causes and characteristics of persistent hypophosphatasemia in a Japanese tertiary care setting. While most cases were associated with known causes, patients with unexplained hypophosphatasemia and symptoms such as chronic pain, muscle weakness, and general fatigue could have adult hypophosphatasia. In such cases, comprehensive evaluation and further investigation for hypophosphatasia should be considered. Persistent hypophosphatasemia of undetermined etiology could be a crucial initial step in diagnostic algorithms for this condition. en-copyright= kn-copyright= en-aut-name=FujiwaraShintaro en-aut-sei=Fujiwara en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OtsukaYuki en-aut-sei=Otsuka en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FurukawaMasanori en-aut-sei=Furukawa en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HigashikageAkihito en-aut-sei=Higashikage en-aut-mei=Akihito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Laboratory Medicine, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Laboratory Medicine, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=chronic fatigue syndrome kn-keyword=chronic fatigue syndrome en-keyword=chronic pain kn-keyword=chronic pain en-keyword=hypophosphatasemia kn-keyword=hypophosphatasemia en-keyword=alkaline phosphatase kn-keyword=alkaline phosphatase en-keyword=hypophosphatasia kn-keyword=hypophosphatasia END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue=3 article-no= start-page=620 end-page=626 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=2023 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=All-in-one terahertz taste sensor: integrated electronic and bioelectronic tongues en-subtitle= kn-subtitle= en-abstract= kn-abstract=Taste sensors, also known as electronic tongues or bioelectronic tongues, are designed to evaluate food and beverages, as well as for medical diagnostics. These devices mimic the ability of the human tongue to detect and identify different tastes in liquid samples, such as sweet, sour, salty, bitter, and umami. In this study, a novel all-in-one terahertz taste sensor was proposed, which differs from traditional electrochemical approaches. This sensor utilizes terahertz technology for imaging and sensing chemical reactions on the terahertz semiconductor emitter surface. The surface can be functionalized with ion-sensitive membranes, proteins, DNA aptamers, and organic receptors, enabling the detection of various substances, such as solution pH, physiological ions, sugars, toxic chemicals, drugs, and explosives. Terahertz taste sensors offer several advantages, including being label-free, high sensitivity and selectivity, rapid response, minimal sample consumption, and the ability to detect non-charged chemical substances. By integrating multiple receptors or sensing materials on a single chip, the all-in-one terahertz taste sensor has significant potential for future taste substance detection, nutrition evaluation, metabolite and drug monitoring, and biomarker sensing. en-copyright= kn-copyright= en-aut-name=WangJin en-aut-sei=Wang en-aut-mei=Jin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakaiKenji en-aut-sei=Sakai en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KiwaToshihiko en-aut-sei=Kiwa en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=159 cd-vols= no-issue=19 article-no= start-page=194504 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231121 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Efficiency and energy balance for substitution of CH4 in clathrate hydrates with CO2 under multiple-phase coexisting conditions en-subtitle= kn-subtitle= en-abstract= kn-abstract=Many experimental and theoretical studies on CH4–CO2 hydrates have been performed aiming at the extraction of CH4 as a relatively clean energy resource and concurrent sequestration of CO2. However, vague or insufficient characterization of the environmental conditions prevents us from a comprehensive understanding of even equilibrium properties of CH4–CO2 hydrates for this substitution. We propose possible reaction schemes for the substitution, paying special attention to the coexisting phases, the aqueous and/or the fluid, where CO2 is supplied from and CH4 is transferred to. We address the two schemes for the substitution operating in three-phase and two-phase coexistence. Advantages and efficiencies of extracting CH4 in the individual scheme are estimated from the chemical potentials of all the components in all the phases involved in the substitution on the basis of a statistical mechanical theory developed recently. It is found that although substitution is feasible in the three-phase coexistence, its working window in temperature–pressure space is much narrower compared to the two-phase coexistence condition. Despite that the substitution normally generates only a small amount of heat, a large endothermic substitution is suggested in the medium pressure range, caused by the vaporization of liquid CO2 due to mixing with a small amount of the released CH4. This study provides the first theoretical framework toward the practical use of hydrates replacing CH4 with CO2 and serves as a basis for quantitative planning. en-copyright= kn-copyright= en-aut-name=TanakaHideki en-aut-sei=Tanaka en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumotoMasakazu en-aut-sei=Matsumoto en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YagasakiTakuma en-aut-sei=Yagasaki en-aut-mei=Takuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=3 en-affil=Division of Chemical Engineering, Graduate School of Engineering Science, Osaka University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=35 cd-vols= no-issue=1 article-no= start-page=65 end-page=73 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230220 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Development of Automatic Inspection Systems for WRS2020 Plant Disaster Prevention Challenge Using Image Processing en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this article, an approach used for the inspection tasks in the WRS2020 Plant Disaster Prevention Challenge is explained. The tasks were categorized into three categories: reading pressure gauges, inspecting rust on a tank, and inspecting cracks in a tank. For reading pressure gauges, the “you only look once” algorithm was used to focus on a specific pressure gauge and check the pressure gauge range strings on the gauge using optical character recognition algorithm. Finally, a previously learned classifier was used to read the values shown in the gauge. For rust inspection, image processes were used to focus on a target plate that may be rusted for rust detection. In particular, it was necessary to report the rust area and distribution type. Thus, the pixel ratio and grouping of rust were used to count the rust. The approach for crack inspection was similar to that for rust. The target plate was focused on first, and then the length of the crack was measured using image processing. Its width was not measured but was calculated using the crack area and length. For each system developed to approach each task, the results of the preliminary experiment and those of WRS2020 are shown. Finally, the approaches are summarized, and planned future work is discussed. en-copyright= kn-copyright= en-aut-name=ShimizuYuya en-aut-sei=Shimizu en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KamegawaTetsushi en-aut-sei=Kamegawa en-aut-mei=Tetsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WangYongdong en-aut-sei=Wang en-aut-mei=Yongdong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TamuraHajime en-aut-sei=Tamura en-aut-mei=Hajime kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TeshimaTaiga en-aut-sei=Teshima en-aut-mei=Taiga kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakanoSota en-aut-sei=Nakano en-aut-mei=Sota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TadaYuki en-aut-sei=Tada en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakanoDaiki en-aut-sei=Nakano en-aut-mei=Daiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SasakiYuichi en-aut-sei=Sasaki en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SekitoTaiga en-aut-sei=Sekito en-aut-mei=Taiga kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=UtsumiKeisuke en-aut-sei=Utsumi en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=NagaoRai en-aut-sei=Nagao en-aut-mei=Rai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=SembaMizuki en-aut-sei=Semba en-aut-mei=Mizuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Okayama University kn-affil= affil-num=2 en-affil=Okayama University kn-affil= affil-num=3 en-affil=Okayama University kn-affil= affil-num=4 en-affil=Okayama University kn-affil= affil-num=5 en-affil=Okayama University kn-affil= affil-num=6 en-affil=Okayama University kn-affil= affil-num=7 en-affil=Okayama University kn-affil= affil-num=8 en-affil=Okayama University kn-affil= affil-num=9 en-affil=Okayama University kn-affil= affil-num=10 en-affil=Okayama University kn-affil= affil-num=11 en-affil=Okayama University kn-affil= affil-num=12 en-affil=Okayama University kn-affil= affil-num=13 en-affil=Okayama University kn-affil= en-keyword=WRS2020 kn-keyword=WRS2020 en-keyword=image processing kn-keyword=image processing en-keyword=auto inspection kn-keyword=auto inspection en-keyword=YOLO kn-keyword=YOLO en-keyword=OCR kn-keyword=OCR END start-ver=1.4 cd-journal=joma no-vol=222 cd-vols= no-issue= article-no= start-page=115374 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Environmental water in Kolkata is suitable for the survival of Vibrio cholerae O1 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Many patients with cholera emerge in Kolkata, India throughout the year. Such emergency indicates that cholera toxin-producing Vibrio cholerae O1 (toxigenic V. cholerae O1) are widespread in Kolkata. This suggests that the suitable conditions for replication of toxigenic V. cholerae O1 is provided in Kolkata. In previous studies, we found that the replication rate of toxigenic V. cholerae O1 is low in the low ionic aqueous solution. Then we measured the ion concentration in the environmental water of Kolkata. As a control, we measured them in Japanese environmental water. The ion concentration in the environmental water of Kolkata was significantly high. Then, we examined the survival of toxigenic V. cholerae O1 in groundwater from Kolkata and found that V. cholerae O1 survive for long time in the solution but not in the solution diluted with Milli Q water. In addition, we found that V. cholerae O1 proliferated in environmental water of Kolkata to which a small amount of nutrient was added, but did not grow in the environmental water diluted with water to which the same amount of nutrient was added. These results indicate that the environmental water from Kolkata is suitable for survival of V. cholerae O1. en-copyright= kn-copyright= en-aut-name=TakahashiEizo en-aut-sei=Takahashi en-aut-mei=Eizo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KitaharaKei en-aut-sei=Kitahara en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyoshiShin-ichi en-aut-sei=Miyoshi en-aut-mei=Shin-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ChowdhuryGoutam en-aut-sei=Chowdhury en-aut-mei=Goutam kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MukhopadhyayAsish K. en-aut-sei=Mukhopadhyay en-aut-mei=Asish K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=DuttaShanta en-aut-sei=Dutta en-aut-mei=Shanta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OchiSadayuki en-aut-sei=Ochi en-aut-mei=Sadayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OkamotoKeinosuke en-aut-sei=Okamoto en-aut-mei=Keinosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Collaborative Research Center of Okayama University for Infectious Diseases in India kn-affil= affil-num=2 en-affil=Collaborative Research Center of Okayama University for Infectious Diseases in India kn-affil= affil-num=3 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences of Okayama University kn-affil= affil-num=4 en-affil=National Institute of Cholera and Enteric Diseases kn-affil= affil-num=5 en-affil=National Institute of Cholera and Enteric Diseases kn-affil= affil-num=6 en-affil=National Institute of Cholera and Enteric Diseases kn-affil= affil-num=7 en-affil=Department of Health Pharmacy, Yokohama University of Pharmacy kn-affil= affil-num=8 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences of Okayama University kn-affil= en-keyword=Environmental water kn-keyword=Environmental water en-keyword=Ion kn-keyword=Ion en-keyword=Prevalence kn-keyword=Prevalence en-keyword=Survival kn-keyword=Survival en-keyword=Vibrio cholerae kn-keyword=Vibrio cholerae END start-ver=1.4 cd-journal=joma no-vol=31 cd-vols= no-issue=2 article-no= start-page=102570 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241202 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Epidemiology and clinical features of patients with tick bites in the Japanese spotted fever-endemic zone en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose: This study aimed to clarify the epidemiology and clinical features of tick bites in a Japanese spotted fever (JSF)-endemic area.
Method: The clinical records of patients with tick bites were retrospectively reviewed based on a survey conducted at Numakuma Hospital, Fukuyama City, Hiroshima, Japan, from 2016 to 2023. Data on basic characteristics, visit dates, residential address, exposure activities, tick-bite sites, and prophylactic antimicrobial prescriptions for each patient with tick bites were collected at the JSF hotspot hospital.
Results: A total of 443 patients with tick bites visited the hospital, of which data on 305 cases (68.8 %) were reviewed. The median age of these patients was 71 years, with a higher proportion of women (63.0 %). One-third of the patients had a preceding history of working in fields, whereas two-thirds had entered mountains or agricultural fields. Nearly 90 % of the patients visited the hospital from April to August, and the most common bite sites were the lower extremities (45.1 %). Most patients (76.1 %) resided in the southern area of Numakuma Hospital. Nearly all patients were prescribed prophylactic antibiotics (minocycline in 87.8 % of cases), and none subsequently developed JSF.
Conclusion: Continued surveillance of patients with tick bites is warranted to better understand changes in the clinical impact of tick-borne diseases. en-copyright= kn-copyright= en-aut-name=FukushimaShinnosuke en-aut-sei=Fukushima en-aut-mei=Shinnosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SumidaTakaomi en-aut-sei=Sumida en-aut-mei=Takaomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KawamataOsamu en-aut-sei=Kawamata en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HidaniYoshimi en-aut-sei=Hidani en-aut-mei=Yoshimi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= affil-num=1 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Numakuma Hospital kn-affil= affil-num=3 en-affil=Numakuma Hospital kn-affil= affil-num=4 en-affil=Numakuma Hospital kn-affil= affil-num=5 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= en-keyword=Global warming kn-keyword=Global warming en-keyword=Japanese spotted fever kn-keyword=Japanese spotted fever en-keyword=Tick bite kn-keyword=Tick bite en-keyword=Tick-borne diseases kn-keyword=Tick-borne diseases END start-ver=1.4 cd-journal=joma no-vol=31 cd-vols= no-issue=2 article-no= start-page=102554 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241105 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Human Papillomavirus vaccination awareness and uptake among healthcare students in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: The vaccination rate for HPV (Human Papillomavirus) has remained significantly low in Japan because of the administrative suspension of active recommendation. This study investigates the awareness and uptake of the HPV vaccine among healthcare students in Japan following the reinstatement of active recommendation for young women in April 2022.
Methods: A web-based survey was administered to 2567 healthcare students from Okayama and Shujitsu Universities in Japan in July 2023. The survey assessed participants' backgrounds, immunization status, awareness of vaccine recommendations, and knowledge of cervical cancer across various demographics, including sex, academic year, and department (Medicine, Health Science, Pharmaceutical, and Dentistry).
Results: The response rate was 36.3 % (933 students; 181 male, 739 female, and 13 unspecified gender). The overall immunization rate among female students was 55.6 %, with higher rates observed in medical (73.8 %) and dental (63.0 %) students. Awareness of the government's change in vaccine recommendation was notably high among female and senior male students. Over half of the female students (54.7 %) reported receiving vaccinations based on their parents' advice. Among those unvaccinated but interested in future immunization, concerns about adverse reactions (47.4 %) and challenges in scheduling vaccinations (29.1 %) were predominant.
Conclusion: Healthcare students exhibited a higher HPV vaccination rate than the general population. Ongoing education to improve vaccine literacy is crucial for augmenting HPV vaccination rates in Japan. en-copyright= kn-copyright= en-aut-name=ShimbeMadoka en-aut-sei=Shimbe en-aut-mei=Madoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OtsukaYuki en-aut-sei=Otsuka en-aut-mei=Yuki 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=YamadaYoichi en-aut-sei=Yamada en-aut-mei=Yoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=4 en-affil=School of Pharmacy, Shujitsu University kn-affil= affil-num=5 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Cervical cancer kn-keyword=Cervical cancer en-keyword=Human Papillomavirus kn-keyword=Human Papillomavirus en-keyword=Immunization kn-keyword=Immunization en-keyword=Vaccine literacy kn-keyword=Vaccine literacy END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue= article-no= start-page=64 end-page=79 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=On the “Chronology of Earthquakes” in the Rika nenpyō (Chronological Scientific Tables): Until the 10th century kn-title=『理科年表』の「地震年代表」をめぐって- 10 世紀まで- en-subtitle= kn-subtitle= en-abstract= kn-abstract=This paper is based on the oral report I gave on July 22, 2023, at the 21st “Disaster Culture and the History of Community Formation” workshop hosted by the Okayama University Research Institute for the Dynamics of Civilizations. I discuss the changes in the “Chronology of Earthquakes” contained within the Rika nenpyō (Chronological Scientific Tables) and some of the problems with them, citing historical earthquake materials. It is necessary to clearly distinguish between real and false earthquakes, such as the Tamba earthquake (701), the Kinai earthquake (734), the Minō earthquake (745), the Ecchū-Echigo earthquake (863), and the Kantō earthquake (878). The author hopes that the “Chronology of Earthquakes” will be published in a better form in the future and calls for efforts in the field of history to verify and introduce historical earthquake materials. en-copyright= kn-copyright= en-aut-name=ARAIHideki en-aut-sei=ARAI en-aut-mei=Hideki kn-aut-name=荒井秀規 kn-aut-sei=荒井 kn-aut-mei=秀規 aut-affil-num=1 ORCID= affil-num=1 en-affil=Historian kn-affil= en-keyword=Ancient Japan kn-keyword=Ancient Japan en-keyword=earthquakes kn-keyword=earthquakes en-keyword=false earthquakes kn-keyword=false earthquakes en-keyword=Chronological Scientific Tables kn-keyword=Chronological Scientific Tables END start-ver=1.4 cd-journal=joma no-vol=45 cd-vols= no-issue=1 article-no= start-page=11 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230323 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Mutation and apoptosis are well-coordinated for protecting against DNA damage-inducing toxicity in Drosophila en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Apoptotic cell death is an important survival system for multicellular organisms because it removes damaged cells. Mutation is also a survival method for dealing with damaged cells in multicellular and also unicellular organisms, when DNA lesions are not removed. However, to the best of our knowledge, no reports have comprehensively explored the direct relationship between apoptosis and somatic cell mutations induced by various mutagenic factors.
Results Mutation was examined by the wing-spot test, which is used to detect somatic cell mutations, including chromosomal recombination. Apoptosis was observed in the wing discs by acridine orange staining in situ. After treatment with chemical mutagens, ultraviolet light (UV), and X-ray, both the apoptotic frequency and mutagenic activity increased in a dose-dependent manner at non-toxic doses. When we used DNA repair-deficient Drosophila strains, the correlation coefficient of the relationship between apoptosis and mutagenicity, differed from that of the wild-type. To explore how apoptosis affects the behavior of mutated cells, we determined the spot size, i.e., the number of mutated cells in a spot. In parallel with an increase in apoptosis, the spot size increased with MNU or X-ray treatment dose-dependently; however, this increase was not seen with UV irradiation. In addition, BrdU incorporation, an indicator of cell proliferation, in the wing discs was suppressed at 6 h, with peak at 12 h post-treatment with X-ray, and that it started to increase again at 24 h; however, this was not seen with UV irradiation.
Conclusion Damage-induced apoptosis and mutation might be coordinated with each other, and the frequency of apoptosis and mutagenicity are balanced depending on the type of DNA damage. From the data of the spot size and BrdU incorporation, it is possible that mutated cells replace apoptotic cells due to their high frequency of cell division, resulting in enlargement of the spot size after MNU or X-ray treatment. We consider that the induction of mutation, apoptosis, and/or cell growth varies in multi-cellular organisms depending on the type of the mutagens, and that their balance and coordination have an important function to counter DNA damage for the survival of the organism. en-copyright= kn-copyright= en-aut-name=Toyoshima-SasataniMegumi en-aut-sei=Toyoshima-Sasatani en-aut-mei=Megumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ImuraFumika en-aut-sei=Imura en-aut-mei=Fumika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HamatakeYuko en-aut-sei=Hamatake en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FukunagaAkihiro en-aut-sei=Fukunaga en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NegishiTomoe en-aut-sei=Negishi en-aut-mei=Tomoe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=School of Nursing, Osaka City University kn-affil= affil-num=5 en-affil=Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Drosophila kn-keyword=Drosophila en-keyword=Apoptosis kn-keyword=Apoptosis en-keyword=Mutation kn-keyword=Mutation en-keyword=Larval wing disc kn-keyword=Larval wing disc en-keyword=X-ray kn-keyword=X-ray en-keyword=Ultraviolet kn-keyword=Ultraviolet en-keyword=Alkylating agents kn-keyword=Alkylating agents en-keyword=Tobacco smoke kn-keyword=Tobacco smoke en-keyword=Acridine orange kn-keyword=Acridine orange en-keyword=BrdU kn-keyword=BrdU END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=3 article-no= start-page=769 end-page=774 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230519 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Review: Nicotinic acetylcholine receptors to regulate important brain activity—what occurs at the molecular level? en-subtitle= kn-subtitle= en-abstract= kn-abstract=Herein, we briefly review the role of nicotinic acetylcholine receptors in regulating important brain activity by controlled release of acetylcholine from subcortical neuron groups, focusing on a microscopic viewpoint and considering the nonlinear dynamics of biological macromolecules associated with neuron activity and how they give rise to advanced brain functions of brain. en-copyright= kn-copyright= en-aut-name=NaraShigetoshi en-aut-sei=Nara en-aut-mei=Shigetoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamagutiYutaka en-aut-sei=Yamaguti en-aut-mei=Yutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsudaIchiro en-aut-sei=Tsuda en-aut-mei=Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Information Engineering, Fukuoka Institute of Technology kn-affil= affil-num=3 en-affil=Chubu University Academy of Emerging Sciences/Center for Mathematical Science and Artificial Intelligence, Chubu University kn-affil= en-keyword=Neuromodulator kn-keyword=Neuromodulator en-keyword=Nichotinic kn-keyword=Nichotinic en-keyword=Acetylcholine kn-keyword=Acetylcholine en-keyword=Receptors kn-keyword=Receptors en-keyword=Brain activity kn-keyword=Brain activity END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue= article-no= start-page=1 end-page=8 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=2023 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Transepidermal Water Loss Estimation Model for Evaluating Skin Barrier Function en-subtitle= kn-subtitle= en-abstract= kn-abstract=Deterioration of skin barrier function causes symptoms such as allergies because it allows various chemical substances to enter the human body. Quantitative evaluation of the thickness and water content of the stratum corneum is useful as a measure of skin barrier function in fields such as dermatology, nursing science, and cosmetics development. The stratum corneum is responsible for most of the skin barrier function, and this function has conventionally been evaluated using transepidermal water loss (TEWL). In this paper, we propose a new model for estimation of TEWL from measurements of the thickness of the stratum corneum and water content of the surface of the stratum corneum, and discuss the results of the measurements. By measuring the thickness and water content of the stratum corneum using confocal laser microscopy and confocal Raman spectroscopy, respectively, and examining the relationship of these variables with TEWL, we established a new potential model for estimating TEWL from these two variables. The correlation coefficient of the validation data was 0.886 and the root mean squared error was 8.18 points. These findings indicate the feasibility of qualitative evaluation of TEWL by measuring the thickness and water content of the stratum corneum. en-copyright= kn-copyright= en-aut-name=UeharaOsamu en-aut-sei=Uehara en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KusuharaToshimasa en-aut-sei=Kusuhara en-aut-mei=Toshimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakamuraTakao en-aut-sei=Nakamura en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Medical Engineering Laboratory, ALCARE Co., Ltd. kn-affil= affil-num=2 en-affil=Department of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= en-keyword=TEWL kn-keyword=TEWL en-keyword=stratum corneum thickness kn-keyword=stratum corneum thickness en-keyword=water content of stratum corneum kn-keyword=water content of stratum corneum END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=cmad074 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230719 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effect of 2-week postpartum check-ups on screening positive for postpartum depression: a population-based cohort study using instrumental variable estimation in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Postpartum depression is experienced by approximately 10% of women and affects the health and development of their children. Although it is recommended that all mothers have the opportunity for early detection and intervention for postpartum depression, it is unclear whether early postpartum check-ups help to reduce postpartum depression.
Objective: The aim of this study was to assess the effect of 2-week postpartum check-ups on screening positive for postpartum depression in Japan.
Methods: This was a population-based cohort study that used the administrative database of Tsuyama, Japan. Participants were women who received postpartum home visits from a public health nurse in Tsuyama during the fiscal years 2017–2019. Data were obtained on participant’s attendance at a 2-week postpartum check-up and their responses on the Edinburgh Postpartum Depression Scale. Owing to the initiation of a publicly funded postpartum check-up programme, participants were pseudo-randomly assigned to receive/not receive a 2-week postpartum check-up. We conducted instrumental variable estimation to assess the causal effects of the check-up on screening positive for postpartum depression.
Results: The characteristics of the 1,382 participants did not differ by fiscal year of childbirth. We found a 6.7% (95% confidence interval 2.2–11.2) reduction in the prevalence of screening positive for postpartum depression as an effect of 2-week postpartum check-ups among women received 1-month postpartum home visits.
Conclusion: The results suggest that 2-week postpartum check-ups are effective in reducing the prevalence of screening positive for postpartum depression among 1-month postpartum women. Despite some limitations, early postpartum care could reduce postpartum depression. en-copyright= kn-copyright= en-aut-name=NakamuraNaoko en-aut-sei=Nakamura en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakashimaYasuko en-aut-sei=Nakashima en-aut-mei=Yasuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Health Promotion Division, Tsuyama City Department of Children’s Health 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= en-keyword=community health planning kn-keyword=community health planning en-keyword=diagnostic screening programmes kn-keyword=diagnostic screening programmes en-keyword=home visits kn-keyword=home visits en-keyword=postpartum depression kn-keyword=postpartum depression en-keyword=postnatal care kn-keyword=postnatal care en-keyword=quasi-experimental study kn-keyword=quasi-experimental study END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=04 article-no= start-page=E351 end-page=E357 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230213 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Degree of pharyngeal deformation caused by pharyngeal endoscopic submucosal dissection is associated with the incidence of aspiration pneumonia en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and study aims Endoscopic submucosal dissection (ESD) is one of the most minimally invasive treatments for superficial squamous cell cancer of the pharynx. However, aspiration pneumonia (AsP) associated with postoperative deformity of the pharynx may occur. The purpose of this study was to investigate the frequency of AsP and the degree of pharyngeal deformity after pharyngeal ESD.
Patients and methods This was a retrospective observational study of patients who underwent pharyngeal ESD at Okayama University Hospital between 2006 and 2017. The degree of pharyngeal deformation was assessed using the pharyngeal deformation grade (PDG). The primary endpoint was the frequency of AsP as a long-term adverse event.
Results Among the 52 patients enrolled, nine developed aspiration pneumonia, with a 3-year cumulative incidence of 9.0 % (95 % confidence interval [CI], 3.3 %–22.0 %). There were 16, 18, 16, and two patients that had PDG 0, 1, 2, and 3, respectively. Patients with a history of radiotherapy, as a treatment of head and neck cancer (44.4 % vs. 11.6 %; P = 0.02) and the high PDG group (PDG 2 and 3) (77.8 % vs. 25.6 %; P = 0.005) had a significantly higher incidence of AsP. The 3-year cumulative incidence rate of AsP after ESD in the high PDG group was significantly higher than that in the low PDG group (PDG 0 and 1) (23.9 % [95 %CI, 9.2.–49.5%] vs. 0 %; P = 0.03).
Conclusions The incidence of aspiration pneumonia in the long-term course after pharyngeal ESD was revealed. The incidence of aspiration pneumonia may be associated with pharyngeal deformity, but further studies are needed. en-copyright= kn-copyright= en-aut-name=AbeMakoto en-aut-sei=Abe en-aut-mei=Makoto

kn-article= en-subject= kn-subject= en-title= kn-title=Trends in the growing impact of group A Streptococcus infection on public health after COVID-19 pandemic: a multicentral observational study in Okayama, Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose Following the COVID-19 pandemic, group A Streptococcus (GAS) infection has been surging worldwide. We aimed to compare the disease burden between notified cases of streptococcal toxic shock syndrome (STSS) and unreported GAS infections.
Methods This is a multicentral observational study, retrospectively performed at seven hospitals in Okayama prefecture in Japan from January 2022, to June 2024. Clinical and microbiological data of patients with positive cultures of GAS were collected from the medical records. Primary outcomes were defined as rates of surgical procedures, intensive care unit (ICU) admission, and in-hospital mortality, which were compared among patients with locally-defined STSS, invasive GAS (iGAS), and non-iGAS infection.
Results GAS was detected in 181 patients, with 154 active cases of GAS infection. The number of patients with GAS infection surged in late 2023. The most common source of infection was skin and soft tissue infections, accounting for 83 cases, including 15 cases of necrotizing fasciitis, and 12 cases (7.8%) were notified to public health authorities as STSS. Among the 25 unreported iGAS cases, 9 (36.0%) underwent surgical intervention, and 4 patients (16.0%) required ICU admission. The mortality rates in the unreported iGAS cases were comparable to those observed in the notified STSS.
Conclusions We highlighted that the number of iGAS infections was twofold higher than that of notified STSS, with comparable mortality rate between these groups, indicating substantial underestimation of the true burden of iGAS. This epidemiological investigation has significant implications for enhancing infectious disease surveillance frameworks and public health policy development. en-copyright= kn-copyright= en-aut-name=FukushimaShinnosuke en-aut-sei=Fukushima en-aut-mei=Shinnosuke 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=IwamotoYoshitaka en-aut-sei=Iwamoto en-aut-mei=Yoshitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakeharaYuko en-aut-sei=Takehara en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamadaHaruto en-aut-sei=Yamada en-aut-mei=Haruto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujitaKoji en-aut-sei=Fujita en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YoshidaMasayo en-aut-sei=Yoshida en-aut-mei=Masayo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakanoYasuhiro en-aut-sei=Nakano en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= affil-num=1 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of General Medicine, NHO Okayama Medical Center kn-affil= affil-num=3 en-affil=Department of General Medicine, NHO Okayama Medical Center kn-affil= affil-num=4 en-affil=Department of Surgery, Okayama Saiseikai General Hospital kn-affil= affil-num=5 en-affil=Department of General Medicine, Okayama City Hospital kn-affil= affil-num=6 en-affil=Department of General Medicine and Infectious Diseases, Tsuyama Chuo Hospital kn-affil= affil-num=7 en-affil=Department of General Medicine, Okayama Kyoritsu Hospital kn-affil= affil-num=8 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= en-keyword=Epidemiology kn-keyword=Epidemiology en-keyword=Group A Streptococcus kn-keyword=Group A Streptococcus en-keyword=Necrotizing fasciitis kn-keyword=Necrotizing fasciitis en-keyword=Streptococcal toxic shock syndrome kn-keyword=Streptococcal toxic shock syndrome en-keyword=Surveillance kn-keyword=Surveillance END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue= article-no= start-page=77 end-page=90 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241216 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Academic Contribution of the Teaching Staff of the Faculty of Letters, Okayama University(2023) kn-title=文学部教員研究活動一覧(2023年度) en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=187 cd-vols= no-issue= article-no= start-page=101 end-page=110 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241206 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Research on Deepening Views of Subjects in Home Economics Training Courses: Incorporate Opportunities to Compare Home Economics and Other Subjects kn-title=家庭科教員養成課程における教科観の深化に関する研究 ― 家庭科と他教科を比較する機会の導入 ― en-subtitle= kn-subtitle= en-abstract= kn-abstract= 本稿では,森・鈴木(2017,2021),詫間・鈴木(2023)で検証した家庭科教員志望の大学生や大学院生の教科観の深化を促す方法を整理するとともに,各方法を取り入れる適切な時期を検討し,家庭科教員養成課程への導入方法を提案することを目的とした。

The characteristics of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) related to COVID-19 have remained uncertain. To elucidate the clinical trend of ME/CFS induced by long COVID, we examined data for patients who visited our outpatient clinic established in a university hospital during the period from Feb 2021 to July 2023.

Methods
Long COVID patients were classified into two groups, an ME/CFS group and a non-ME/CFS group, based on three diagnostic criteria.

Results
The prevalence of ME/CFS in the long COVID patients was 8.4% (62 of 739 cases; female: 51.6%) and factors related to ME/CFS were severe illness, smoking and alcohol drinking habits, and fewer vaccinations. The frequency of ME/CFS decreased from 23.9% in the Preceding period to 13.7% in the Delta-dominant period and to 3.3% in the Omicron-dominant period. Fatigue and headache were commonly frequent complaints in the ME/CFS group, and the frequency of poor concentration in the ME/CFS group was higher in the Omicron period. Serum ferritin levels were significantly higher in female patients in the ME/CFS group infected in the Preceding period. In the ME/CFS group, the proportion of patients complaining of brain fog significantly increased from 22.2% in the Preceding period to 47.9% in the Delta period and to 81.3% in the Omicron period. The percentage of patients who had received vaccination was lower in the ME/CFS group than the non-ME/CFS group over the study period, whereas there were no differences in the vaccination rate between the groups in each period.

Conclusion
The proportion of long COVID patients who developed ME/CFS strictly diagnosed by three criteria was lower among patients infected in the Omicron phase than among patients infected in the other phases, while the proportion of patients with brain fog inversely increased. Attention should be paid to the variant-dependent trends of ME/CFS triggered by long COVID (300 words). en-copyright= kn-copyright= en-aut-name=MoritaSatoru en-aut-sei=Morita en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TokumasuKazuki en-aut-sei=Tokumasu en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OtsukaYuki en-aut-sei=Otsuka en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HondaHiroyuki en-aut-sei=Honda en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakanoYasuhiro en-aut-sei=Nakano en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SunadaNaruhiko en-aut-sei=Sunada en-aut-mei=Naruhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SakuradaYasue en-aut-sei=Sakurada en-aut-mei=Yasue kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MatsudaYui en-aut-sei=Matsuda en-aut-mei=Yui kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SoejimaYoshiaki en-aut-sei=Soejima en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=UedaKeigo en-aut-sei=Ueda en-aut-mei=Keigo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=11 ORCID= affil-num=1 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=6 article-no= start-page=475 end-page=483 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202412 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=C-arm Free Unilateral Biportal Endoscopic Discectomy: A Technical Note en-subtitle= kn-subtitle= en-abstract= kn-abstract=This report presents a new unilateral biportal endoscopic (UBE) technique for lumbar disc herniation without C-arm guidance. Lumbar disc herniation requires surgical intervention when conservative methods fail. Shifts towards minimally invasive percutaneous endoscopic lumbar discectomy, including uniportal and biportal approaches, have been hindered by challenges such as steep learning curves and reliance on radiation-intensive C-arm guidance. We here describe the use of standard intraoperative navigation in UBE to reduce radiation exposure and increase surgical accuracy. A 24-year-old man with low back and bilateral leg pain with gait disturbance was referred to our hospital. He had had conservative treatment for 12 months in another hospital before admission, but this proved unsuccessful. On admission he had low back pain (VAS 4/10) and bilateral leg pain (VAS 8/10), muscle weakness of the bilateral legs (manual muscle testing (MMT) grade of the extensor hallucis longus: 4/4), and numbness of the bilateral lower legs. Preoperative lumbar MRI showed L4/5 large central disc herniation. He underwent C-arm free UBE discectomy under the guidance of O-arm navigation. The surgery was successful, with postoperative lumbar MRI showing good decompression of the dural sac and bilateral L5 nerve roots. The MMT grade and sensory function of both legs had recovered fully on final follow-up at one year. The new UBE technique under navigation guidance was shown to be useful for lumbar disc herniation. This innovative technique was safe and accurate for the treatment of lumbar intervertebral disc herniation, and minimized radiation exposure to surgeons. en-copyright= kn-copyright= en-aut-name=XiangHongfei en-aut-sei=Xiang en-aut-mei=Hongfei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LatkaKajetan en-aut-sei=Latka en-aut-mei=Kajetan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MastePraful en-aut-sei=Maste en-aut-mei=Praful kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaMasato en-aut-sei=Tanaka en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KumawatChetan en-aut-sei=Kumawat en-aut-mei=Chetan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AratakiShinya en-aut-sei=Arataki en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FujiwaraYoshihiro en-aut-sei=Fujiwara en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TaokaTakuya en-aut-sei=Taoka en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MiyamotoAkiyoshi en-aut-sei=Miyamoto en-aut-mei=Akiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=9 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= en-keyword=lumbar disc herniation kn-keyword=lumbar disc herniation en-keyword=unilateral biportal endoscopic technique kn-keyword=unilateral biportal endoscopic technique en-keyword=navigation kn-keyword=navigation en-keyword=O-arm kn-keyword=O-arm en-keyword=minimally invasive spine surgery (MISS) kn-keyword=minimally invasive spine surgery (MISS) END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=6 article-no= start-page=469 end-page=474 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202412 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Treatment of Tenosynovial Giant Cell Tumor of the Cervical Spine with Postoperative Anti-RANKL Antibody (Denosumab) Administration en-subtitle= kn-subtitle= en-abstract= kn-abstract=Tenosynovial giant cell tumor (TGCT) is a fibrous histiocytic tumor originating in the synovial membrane.

We present a case of traumatic neuroma arising in the cystic duct after cholecystectomy. A 66-year-old man was referred to our department due to a biliary tumor. He had undergone cholecystectomy 20 years prior. Cholangioscopy showed an elevated lesion covered with smooth mucosa. Histological examination revealed normal bile duct mucosa. Although benign disease was suspected, the possibilities of malignant disease could not be excluded. Extrahepatic bile duct resection was planned to include intraoperative rapid-freezing of a biopsy specimen followed by histopathological examination. These intraoperative histology results showed proliferation of nerve and fibrous tissue only, resulting in the diagnosis of traumatic neuroma, so no lymph nodes were removed. To avoid excessive surgical intervention, histopathological examination of an intraoperative rapid-frozen biopsy specimen may be important for diagnosing traumatic neuroma. en-copyright= kn-copyright= en-aut-name=SakamotoShinya en-aut-sei=Sakamoto en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TabuchiMotoyasu en-aut-sei=Tabuchi en-aut-mei=Motoyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YoshimatsuRika en-aut-sei=Yoshimatsu en-aut-mei=Rika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsumotoManabu en-aut-sei=Matsumoto en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IwataJun en-aut-sei=Iwata en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OkabayashiTakehiro en-aut-sei=Okabayashi en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Kochi Health Sciences Center kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Kochi Health Sciences Center kn-affil= affil-num=3 en-affil=Department of Radiology, Kochi Health Sciences Center kn-affil= affil-num=4 en-affil=Department of Diagnostic Pathology, Kochi Health Sciences Center kn-affil= affil-num=5 en-affil=Department of Diagnostic Pathology, Kochi Health Sciences Center kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Kochi Health Sciences Center kn-affil= en-keyword=traumatic neuroma kn-keyword=traumatic neuroma en-keyword=biliary stricture kn-keyword=biliary stricture en-keyword=cholecystectomy kn-keyword=cholecystectomy en-keyword=cholangiography kn-keyword=cholangiography en-keyword=intraoperative rapid-frozen biopsy kn-keyword=intraoperative rapid-frozen biopsy END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=6 article-no= start-page=453 end-page=458 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202412 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Case of Radiation-Induced Angiosarcoma after Breast-Conserving Surgery with Hypofractionated Radiotherapy in a Japanese Patient en-subtitle= kn-subtitle= en-abstract= kn-abstract=Radiation-induced angiosarcoma (RIAS) is a rare, late adverse event of radiotherapy comprising approximately half of all radiation-induced sarcomas. It has a relatively short latency period and generally unfavorable prognosis. This study presents a case of RIAS that developed 5 years and 11 months after the completion of hypofractionated radiotherapy (42.56 Gy/16 fractions) following partial mastectomy. The patient was diagnosed with RIAS 10 months after the onset of skin redness. She underwent skin tumor resection, followed by paclitaxel, then pazopanib administration, but no radiotherapy. At 6 years and 2 months after surgery, no RIAS recurrence has been detected. en-copyright= kn-copyright= en-aut-name=KawataYujiro en-aut-sei=Kawata en-aut-mei=Yujiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WatanabeKenta en-aut-sei=Watanabe en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TokiyaRyoji en-aut-sei=Tokiya en-aut-mei=Ryoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsunoTakeshi en-aut-sei=Matsuno en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanakaRyo en-aut-sei=Tanaka en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TairaNaruto en-aut-sei=Taira en-aut-mei=Naruto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KatsuiKuniaki en-aut-sei=Katsui en-aut-mei=Kuniaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Radiology, Kawasaki Medical School kn-affil= affil-num=2 en-affil=Department of Radiology, Kawasaki Medical School kn-affil= affil-num=3 en-affil=Department of Radiology, Kawasaki Medical School kn-affil= affil-num=4 en-affil=Department of Pathology, Kawasaki Medical School kn-affil= affil-num=5 en-affil=Department of Dermatology, Kawasaki Medical School kn-affil= affil-num=6 en-affil=Department of Breast and Thyroid Surgery, Kawasaki Medical School kn-affil= affil-num=7 en-affil=Department of Radiology, Kawasaki Medical School kn-affil= en-keyword=breast cancer kn-keyword=breast cancer en-keyword=hypofractionated radiotherapy kn-keyword=hypofractionated radiotherapy en-keyword=radiation-induced angiosarcoma kn-keyword=radiation-induced angiosarcoma END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=6 article-no= start-page=439 end-page=447 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202412 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Risk Factors for Gangrenous Cholecystitis and the Outcomes of Early Cholecystectomy: A Retrospective Study of a Single-Center City General Hospital en-subtitle= kn-subtitle= en-abstract= kn-abstract=Gangrenous cholecystitis (GC) is classified as moderate acute cholecystitis according to the Tokyo Guidelines from 2018 (TG18). We evaluated the risk factors for GC and the outcomes of early cholecystectomy. A total of 136 patients who underwent emergency cholecystectomy for acute cholecystitis were retrospectively analyzed; 58 of these patients (42.6%) were diagnosed with GC (GC group) based on our retrospective pathologic diagnosis. We comparatively evaluated the patient backgrounds and surgical outcomes between the GC group and non-GC group. The GC group was significantly older and included more hypertensive patients than the non-GC group. The GC group was prescribed more antibiotics as initial treatment than the non-GC group, and they had more days between onset and surgery. The preoperative white blood cell count and C-reactive protein values were significantly higher in the GC group than in the non-GC group, and these values were predictive factors for GC. Cholecystectomy required a longer operation time and caused greater blood loss in the GC group. The GC group also had longer hospitalization times than the non-GC group; however, no significant differences were observed in terms of postoperative complications. In conclusion, gangrenous changes should be assessed when diagnosing cholecystitis, and appropriate treatment, such as surgery or drainage, should be undertaken. en-copyright= kn-copyright=
