Here, we describe the epidemiological trends of cases of RSV infection among children reported during 2018-2021 in Japan based on the national surveillance system. Compared with 2018 and 2019, 2020 saw an unprecedented decrease in notifications of RSV infection per sentinel site. However, 2021 experienced an unseasonably early and high peak at week 28 (peak week in 2018 and 2019 was week 37), with a large resurgence in notifications nationwide and across regions. Regarding age, compared with 2018 and 2019, the number and proportion of case-patients aged 2, 3, and ≥4-years increased substantially in 2021, but the number of case-patients aged <1 year decreased slightly. Furthermore, in 2021, the ratio of notifications per site from outpatient clinics to notifications per site from hospitals increased, suggesting a proportionate increase in diagnoses of clinically milder cases. Notably, RSV-attributed deaths from vital statistics also dropped substantially in 2020 and rebounded in 2021 but were fewer than in 2018 or 2019. While the incidence of RSV infections likely declined in 2020 (possibly owing to COVID-19 countermeasures) and increased in 2021, notifications in 2021 appeared to be associated with milder presentations. Given the unpredictable epidemiology of RSV, continuous monitoring and pluralistic assessments are imperative.","PeriodicalId":14608,"journal":{"name":"Japanese journal of infectious diseases","volume":" ","pages":"51-54"},"PeriodicalIF":1.3,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142346834","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}

A joint detection factor model was constructed, and a receiver operating characteristic curve was drawn. A nomogram was established using the R language, and its efficiency in diagnosing SFTS was evaluated using a calibration curve. Patients in the deceased group were more likely to be older, have a shorter hospitalization stay, and have renal and multiple organ failure than those in the survival group. Statistically significant differences were observed in the neutrophil percentage, lymphocyte percentage, neutrophil-to-lymphocyte ratio, platelet (PLT) count, aspartate aminotransferase (AST)/alanine transaminase (ALT) ratio, AST, blood urea nitrogen, lactate dehydrogenase, hydroxybutyrate dehydrogenase, thromboplastin time, and activated partial thromboplastin time between the two groups. Lymphocyte percentage, PLT count, and the AST/ALT ratio were independent risk factors for mortality in patients with SFTS.

In this study, we investigated the viral load in the nasopharyngeal samples of patients with SARS-CoV-2 in Gunma prefecture, Japan, from April 2, 2020, to April 1, 2023. The amount of virus in samples in the Omicron-variant-prevalent period was higher than that of strains detected in samples before week 50 of 2020, the B.1.1.284-prevalent period, the Alpha-variant-prevalent period, and the Delta-variant- prevalent period. Moreover, among Omicron variants, the sublineage BA.5-prevalent period showed higher amount of virus in the samples than BA.1-prevalent period and BA.2-prevalent period. Hence, the new variant may have been able to release more viruses into the nasopharyngeal samples during the process of repeated mutations, resulting in widespread infection. The amount of virus detected in the nasopharyngeal samples showed an increasing tendency with the evolution of the virus. Therefore, considering that the amount of virus in specimens is also vital factor contributing to the spread of infection, it is important to examine this factor in samples.","PeriodicalId":14608,"journal":{"name":"Japanese journal of infectious diseases","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142931719","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 reviewed the medical records of patients who tested positive for Trichomonas vaginalis (T. vaginalis) at the National Center for Global Health and Medicine between August 2011 and May 2023. Refractory vaginal trichomoniasis was defined as the failure after the initial MNZ treatment. During the study period, nine cases of vaginal trichomoniasis were identified, six of which were refractory to treatment for T. vaginalis. Four patients were cured with a combination of oral and vaginal tinidazole (TNZ) therapy, one with oral TNZ and one with two doses of MNZ. Possible causes of treatment failure include MNZ-resistant T. vaginalis, reinfection between partners, and infections of other sexual transmitted diseases. However, the fact that TNZ was effective suggests that MNZ-resistant T. vaginalis may have been the cause. Although MNZ resistance testing was not performed in this study, treatment with TNZ should be considered in cases of refractory vaginal trichomoniasis, possibly caused by MNZ-resistant T. vaginalis.","PeriodicalId":14608,"journal":{"name":"Japanese journal of infectious diseases","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142931727","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}

This system is applied to influenza and pediatric infectious diseases but not to respiratory syncytial virus (RSV) infection, whose incorporation is essential for early epidemic detection. We aimed to propose criterion values for the epidemic warning system of RSV infection within PHC areas. We analyzed the weekly number of RSV infection cases reported by sentinel medical institutions (SMIs) in the NESID from 2015 to 2019. Weekly cases per SMI in the PHC area were set for an index for epidemic warnings. We determined the criteria for issuing an epidemic warning by describing the percentiles of the distribution of the index. Setting the critical values for the onset and end of the epidemic warning at 5 and 2, respectively, yielded an approximately 5% annual proportion of PHC areas with an epidemic warning. This aligns with the acceptably implemented frequency of epidemic warnings. The 5-year (2015-2019) RSV infection epidemic trend showed that the set critical values were appropriate. Using these values could help issue warnings regarding potential RSV infection epidemics in Japan.","PeriodicalId":14608,"journal":{"name":"Japanese journal of infectious diseases","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142931734","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 included a total of 87 individuals who reported the type of mask worn. We dichotomized the types of mask into non-woven masks or other types of mask, such as cloth or urethane masks. We then examined the associations between the mask type and SARS-CoV-2 infection using logistic regression analysis, adjusting for potential confounders. Participants who wore non-woven masks were less likely to be infected with SARS-CoV-2 (9.7%) compared with those who wore other types of mask (26.7%).
