Few studies have analyzed only transtrochanteric fractures. The purpose of this study was to assess whether surgery within two days of admission reduces the incidence of pneumonia, deep vein thrombosis, pulmonary embolism, pressure ulcers, and mortality during hospitalization in patients with older adult transtrochanteric femur fractures. In this retrospective study, we used the Japanese National Administrative DPC (Diagnosis Procedure Combination) database that covers April 2016 to March 2022. Transtrochanteric femur fracture was included in patients aged 65 years or older who underwent surgery. The perioperative complications with pneumonia, deep vein thrombosis, pulmonary embolism, pressure ulcers, and mortality during hospitalization were assessed after propensity score matching, focusing on surgeries conducted within two days of admission. After one-to-one propensity score matching for age, sex, and comorbidity, we identified 79,649 pairs of patients who underwent surgery either within two days or after the third day of admission. Surgery delayed beyond two days was independently associated with increased pneumonia, pulmonary embolism, pressure ulcers, and mortality during hospitalization with risk ratios of 1.335 (95% CI: 1.256-1.418, p < 0.0001), 1.287 (95% CI: 1.225-1.351, p < 0.0001), 1.229 (95% CI: 1.094-1.380, p < 0.0001), and 1.063 (95% CI: 0.978-1.155, p = 0.0035), respectively. Surgery within two days of admission for transtrochanteric femur fracture effectively prevents perioperative complications and reduces mortality during hospitalization.","PeriodicalId":23187,"journal":{"name":"Tohoku Journal of Experimental Medicine","volume":" ","pages":"211-219"},"PeriodicalIF":1.7,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142296209","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 conducted a retrospective study on 19 patients (10 males and 9 females) who underwent lower limb amputation for musculoskeletal malignancies between 2003 and 2011 and were followed up until 2021.

Whether high HOXA1 expression correlated with the clinical characteristics and prognosis of LC patients was analyzed. LC cell viability and sensitivity to cisplatin were determined by Methyl thiazolyl tetrazolium assay. The cell migration, invasion, and cell cycle after transfection were examined by Wound healing, Transwell, and flow cytometry assays, respectively. The corresponding mRNA and protein expressions were measured by quantitative real-time PCR or Western blot. A higher expression of HOXA1 was detected in LC tissues, which was found to be relevant to poor prognosis of LC patients. The association of high expression of HOXA1 with lymph node and clinical stage was also confirmed. Silencing of HOXA1 in LC cells enhanced the cell sensitivity to cisplatin, inhibited viability, migration, invasion and cell cycle, and reduced N-Cadherin, Vimentin, PCNA, p-AKT and p-mTOR expressions, while overexpression of HOXA1 had the opposite effects.
