Due to varying economic and cultural backgrounds, there are significant differences in clinical treatment practices and related basic research on lung cancer between Japan and China. These differences are mainly reflected in many aspects, such as cancer prevention, cancer treatment, provision of medical insurance, patient compliance, medical education system, and sources of research funding. By understanding these differences, Japan and China can learn from each other, make progress together, and strengthen further exchanges and cooperation, which will help improve the long-term efficacy of lung cancer treatment and improve patients' clinical outcomes.</p>","PeriodicalId":13719,"journal":{"name":"Internal Medicine","volume":" ","pages":"2524-2533"},"PeriodicalIF":1.1,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12463414/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143537021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A bioelectrical impedance analysis (BIA) is a noninvasive method for measuring human body composition. A direct association between serum hemoglobin (Hb) levels and the extracellular water-to-total body water (ECW/TBW) ratio, as measured by a BIA in patients with diabetes, has been reported. However, the predictive value of the ECW/TBW ratio for detecting anemia in patients with CVD has not been fully elucidated. Methods We conducted a study involving consecutive patients admitted to our cardiology department from January 1, 2021, to December 31, 2022. A BIA was performed once during hospitalization for all patients, whenever possible. The correlation between the Hb level and ECW/TBW ratio was assessed. The predictive accuracy for anemia was evaluated using a receiver operating characteristic (ROC) curve analysis. Results The ECW/TBW ratio was significantly higher in the anemia group than in the non-anemia group [0.41 (0.40, 0.41) vs. 0.39 (0.38, 0.40), p<0.001]. The ECW/TBW ratio exhibited a significant negative correlation with Hb, with an R value of 0.57 and a p value of <0.01. However, this correlation coefficient decreased to 0.45 among subjects with B-type natriuretic peptide (BNP) levels ≥200 pg/mL. The area under the ROC curve (AUC) for the ECW/TBW ratio for detecting anemia was 0.83. However, its predictive performance decreased in patients with BNP levels exceeding 200 pg/mL, with an AUC of 0.71. Conclusion The BIA-derived ECW/TBW ratio is a valuable predictor of anemia in patients with CVD, provided BNP levels are not elevated.</p>","PeriodicalId":13719,"journal":{"name":"Internal Medicine","volume":" ","pages":"2534-2540"},"PeriodicalIF":1.1,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12463406/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143639710","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
