We evaluated the relationship between in-hospital mortality and weekend admission in adult patients with AML in Japan by conducting a retrospective observational study using administrative data from 144 acute care hospitals from which patients were discharged between April 2014 and March 2019. The primary endpoint was in-hospital mortality, compared between weekend and weekday admissions. Among the 1,340 eligible patients, 11% (150) were admitted during a weekend. The in-hospital mortality rates of the patients admitted during weekends and those admitted on a weekday were 28% (42/150) and 17% (204/1190), respectively. After an adjustment for covariates, weekend admission was associated with a significantly higher risk of in-hospital mortality than weekday admission (HR 1.70, 95%CI: 1.20-2.40; p=0.003). However, such an association was not observed in patients treated in a bio-clean room (HR 1.26, 95%CI: 0.65-2.42). Our results demonstrate that for patients with AML, weekend admission was independently associated with a higher risk of death during hospitalization. An appropriate system is necessary for these patients.","PeriodicalId":7017,"journal":{"name":"Acta medica Okayama","volume":"79 6","pages":"431-436"},"PeriodicalIF":0.6,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145825623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":7017,"journal":{"name":"Acta medica Okayama","volume":"79 5","pages":"321-328"},"PeriodicalIF":0.6,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145342552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We developed SPAPS, a technique allowing two surgeons to perform anterior LLIF and posterior PPS insertion simultaneously in a single lateral decubitus position. This retrospective study compared SPAPS (SPAPS-LLIF, Group SL) and minimally invasive posterior/transforaminal lumbar interbody fusion (MIS-PLIF/TLIF, Group PT) in patients treated between 2016 and 2019 with a two-year follow-up. Operative time, estimated blood loss (EBL), length of hospital stay (LOS), JOABPEQ and VAS scores, segmental lordotic angle, lumbar lordotic angle, segmental Cobb's angle, PPS misplacement, PPS loosening, fusion status, and muscle cross-sectional areas were compared. Fifty-two patients were analyzed (Group SL: 25; Group PT: 27). SPAPS significantly reduced operative time (118.0 vs. 165.3 min, p <0.01) and estimated blood loss (8.6 vs. 164.1 mL, p<0.01). While clinical outcomes and hospital stay were comparable, Group SL had significantly lower PPS loosening (0% vs. 13%, p<0.01) and non-union rates (0% vs. 22.2%, p=0.02). Multifidus muscle atrophy was also less in Group SL (-14.3 vs. -121.5 mm2, p<0.01). SPAPS demonstrated advantages in reducing surgical invasiveness without compromising clinical efficacy, offering a promising alternative to conventional posterior fusion surgery.","PeriodicalId":7017,"journal":{"name":"Acta medica Okayama","volume":"79 5","pages":"359-368"},"PeriodicalIF":0.6,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145342588","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":7017,"journal":{"name":"Acta medica Okayama","volume":"79 5","pages":"369-379"},"PeriodicalIF":0.6,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145342606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
