This study aimed to examine the crude and adjusted prevalence of diseases between employee and nonemployee health insurance in Japan.Methods: We conducted a cross-sectional study using the DeSC database, an administrative claims database covering multiple insurers. We calculated the prevalence of 10 disease categories and 6 specific cancers with and without adjustments for age and sex and compared them between the employee (Kempo) and nonemployee (Kokuho) insurance systems.Results: We identified 740,217 and 3,312,042 individuals covered by Kempo and Kokuho, respectively. The Kokuho group showed a higher crude prevalence of malignancies, endocrinological diseases, mental disorders, neurological diseases, cardiovascular diseases, and kidney or genitourinary diseases. The adjusted prevalence differed in mental disorders (7.2% vs. 10.6%), neurological diseases (10.5% vs. 14.0%), and gastrointestinal diseases (50.1% vs. 34.1%) between the Kempo and Kokuho groups.Conclusions: While using administrative claims data, researchers should consider differences in patient backgrounds and disease prevalence among insurance providers.","PeriodicalId":73550,"journal":{"name":"JMA journal","volume":"8 2","pages":"411-416"},"PeriodicalIF":1.5,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12095125/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144144718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although its prognosis can be good, this type of breast cancer is characterized by a high incidence of late recurrence. However, to the best of our knowledge, there are no publications showing prognostic value regarding the invasive-disease-free survival (IDFS) and distant relapse-free survival in this group in clinical practice. Therefore, this study examined the clinical data and prognosis of patients participating in the MonarchE trial.Methods: This study included patients who underwent surgery at Tokyo Metropolitan Komagome Hospital and whose corresponding prognosis to the Monarch E trial could be followed up.Results: The total number of participants was 152, of whom 104 (68%) were treated with chemotherapy. Seventy-five patients (49%) were postmenopausal. The IDFS after 5 years was 85.0%. Although IDFS did not differ in terms of the menstrual status, premenopausal patients tended to receive a higher proportion of tamoxifen, and there was a greater number of patients treated with chemotherapy. However, neither chemotherapy nor menstrual statuses were found to affect the IDFS incidence.Conclusions: Real clinical data applicable to the MonarchE study were examined. Our univariate analysis revealed that there were no factors affecting IDFS.","PeriodicalId":73550,"journal":{"name":"JMA journal","volume":"8 2","pages":"486-497"},"PeriodicalIF":1.5,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12095113/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144144609","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients residing in areas with limited acute care access may not receive prompt treatment; however, the association between accessibility to acute care and discharge outcomes in patients with AIS remains controversial. This study aimed to clarify the association between acute care density index (ACDI) and home-to-hospital distance and in-hospital mortality in patients with AIS.Methods: Using the Japanese registry of all cardiac and vascular diseases-diagnosis procedure combination database, we examined 525,689 patients (from April 2015 to March 2020). Hospital accessibility was assessed using ACDI and home-to-hospital distance. The patient residences were classified as urban, rural, or depopulated.Results: In urban areas, ACDI was associated with in-hospital mortality, with adjusted odds ratios for Q2, Q3, and Q4 compared with Q1 of 1.16 (95% confidence interval: 1.02-1.31), 1.23 (1.10-1.39), and 1.35 (1.19-1.53), respectively. Similar trends were observed in rural areas. In depopulated areas, home-to-hospital distance exceeding the median was associated with a reduction in in-hospital mortality, with adjusted odds ratios for Q3 and Q4 compared with Q1 of 0.84 (0.74-0.95) and 0.78 (0.68-0.89), respectively.Conclusions: A lower ACDI was associated with higher in-hospital mortality in both urban and rural areas, whereas longer home-to-hospital distance was not necessarily associated with higher in-hospital mortality.","PeriodicalId":73550,"journal":{"name":"JMA journal","volume":"8 2","pages":"417-429"},"PeriodicalIF":1.5,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12095654/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144144753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the current burden of vectorial transmission from natural reservoirs to humans is unclear. This study aimed to clarify the active mode of transmission to humans disentangled from the feeding pattern of Triatoma dimidiata (T. dimidiata) infected by Trypanosoma cruzi (T. cruzi).Methods: A total of 1,376 T. dimidiata specimens were collected across the 14 departments of El Salvador. From these specimens, 135 midgut samples from 37 households in eight departments were positive for T. cruzi (n = 135/1,376; 9.8% [95% confidential interval (CI): 8.35%-11.5%]). Using a universal vertebrate primer, vertebrate blood sources were positively identified by next-generation sequence analysis of deoxyribonucleic acid (DNA) extracted from the midgut contents of T. dimidiata.Results: A total of 13 vertebrates were detected as blood sources; humans, and five domestic, three synanthropic, and four sylvatic species. Triatomines identified as having fed on human blood accounted for approximately 67% (n = 90/135 [95% CI: 58.3%-74.1%]) of the samples analyzed.Conclusions: In this study, a holistic understanding of the feeding patterns of T. cruzi-positive T. dimidiata in El Salvador is dated. The detection of human DNA in the midgut contents of T. dimidiata indicated the possibility of active vectorial transmission to humans.","PeriodicalId":73550,"journal":{"name":"JMA journal","volume":"8 2","pages":"432-443"},"PeriodicalIF":1.5,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12095551/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144144857","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
