Intraoperative Tranexamic Acid Infusion Reduces Perioperative Blood Loss in Pediatric Limb-Salvage Surgeries: A Double-Blinded Randomized Placebo-Controlled Trial.
J Bone Joint Surg Am
January 2025
National Cancer Institute, Cairo University, Giza, Egypt.
Background: Limb-salvage surgery for malignant bone tumors can be associated with considerable perioperative blood loss. The aim of this randomized controlled trial was to assess the safety and efficacy of the intraoperative infusion of tranexamic acid (TXA) in children and adolescents undergoing limb-salvage surgery.
Methods: All participants were <18 years of age at the time of surgery and diagnosed with a malignant bone tumor of the femur that was treated with resection and reconstruction with a megaprosthesis.
Functional assessment of genetic variants in thrombomodulin detected in patients with bleeding and thrombosis.

Thrombomodulin (TM) expressed on endothelial cells regulates coagulation. Specific nonsense variants in the TM gene, THBD, result in high soluble TM levels causing rare bleeding disorder. In contrast, though THBD variants have been associated with venous thromboembolism, this association remains controversial.

Division of Trauma & Surgical Critical Care, DeWitt Daughtry Family Department of Surgery, Ryder Trauma Center, University of Miami Miller School of Medicine, Miami, FL, USA.
Background: Venous thromboembolism (VTE) remains a major source of morbidity and mortality in severely injured patients despite current methods of risk stratification and prophylaxis, suggesting incomplete understanding of VTE risk factors. Given the liver's role in coagulation, we hypothesized that liver injury (LI) is associated with increased rates of VTE in severely injured patients.
Study Design: The American College of Surgeons Trauma Quality Improvement Project database (TQIP) 2017-2021 was retrospectively reviewed for patients with a maximum abdominal Abbreviated Injury Score (AIS) ≥ 4 with or without LI.
Combination of Biological Aging and Genetic Susceptibility Helps Identifying At-Risk Population of Venous Thromboembolism: A Prospective Cohort Study of 394 041 Participants.

Phenotypic age acceleration (PhenoAgeAccel) is a novel clinical aging indicator. This study was carried out to investigate the relationship between PhenoAgeAccel and the incidence of VTE, as well as to integrate PhenoAgeAccel with genetic susceptibility to improve risk stratification of VTE. The study included 394 041 individuals from the UK Biobank.

Department of Neurology, Xuanwu Hospital, Capital Medical University, Beijing, China.
Hematologic diseases are considered important contributors to cerebral venous sinus thrombosis (CVST) cases. This retrospective study aims to compare the difference of the clinical and radiological characters between CVST patients with and without hematologic diseases. Consecutive hospitalized CVST patients with hematologic disorders constituted the hematologic disorder group, while that without identifiable risk factors comprised the control group in this study.
