Background: Spinal fracture is a common traumatic condition in orthopaedics, accounting for 5%-6% of total body fractures, and is a high-risk factor for venous thromboembolism (VTE), which seriously affects patient prognosis.
Aim: The aim of this study was to determine the impact of VTE prophylaxis on the prognosis of patients with spinal fractures in intensive care units (ICUs) and to provide a scientific basis for clinical treatment and nursing.
Design: A retrospective study of patients with spinal fractures from the multicenter eICU Collaborative Research Database.
Method: The outcomes of this study were ICU mortality and in-hospital mortality. Patients were divided into the VTE prophylaxis (VP) and no VTE prophylaxis (NVP) groups according to whether they had undergone VTE prophylaxis during their ICU admission. The association between groups and outcomes were analysed using Kaplan-Meier (KM) survival curve, log-rank test and the Cox proportional-hazards regression model.
Results: This study included 1146 patients with spinal fractures: 330 in the VP group and 816 in the NVP group. KM survival curves and log-rank tests revealed that both ICU and in-hospital survival probabilities in the VP group were significantly higher than in the NVP group. After the Cox model was adjusted for all covariates, the hazard ratio for ICU mortality in the VP group was 0.38 (0.19-0.75); the corresponding value for in-hospital mortality in the VP group was 0.38 (0.21-0.68).
Conclusions: VTE prophylaxis is associated with reduced ICU and in-hospital mortality in patients with spinal fractures in ICUs. More research is necessary to further define specific strategies and optimal timing for VTE prophylaxis.
Relevance To Clinical Practice: This study provides the basis that VTE prophylaxis may be associated with improved prognosis in patients with spinal fractures in ICUs. In clinical practice, an appropriate modality should be selected for VTE prophylaxis in such patients.

Background: Pregnancy-associated venous thromboembolism (PA-VTE) seriously threatens maternal health. We aimed to investigate the clinical characteristics, risk factors, treatments, and pregnancy outcomes to better prevent and treat PA-VTE.
Methods: PA-VTE patients were selected from 171,898 women who were registered in the Department of Obstetrics of Fujian Maternity and Child Health Hospital from January 2014 to August 2023 and delivered to calculate the incidence.
Efficacy and safety of rivaroxaban in preventing venous thromboembolism in postoperative patients with gynecological malignancies: protocol for a randomised controlled open-label trial (G-alfalfa trial).

Introduction: Compared with the guideline-recommended use of low-molecular weight heparin (LMWH) for 28 days to prevent venous thromboembolism (VTE) after cytoreductive surgery, oral rivaroxaban avoids the pain and inconvenience of daily injections and reduces medical expenses. The proposed randomised controlled trial (RCT) aims to compare the efficacy and safety of rivaroxaban and enoxaparin in preventing VTE in patients after surgery for gynaecological malignancies and to provide a reference for clinical medication prevention.
Methods And Analysis: This is a single-centre, randomised, controlled, open-label and assessor-blind clinical trial.

Traumatic brain injury (TBI) remains a leading cause of morbidity and mortality among trauma patients. The care of these patients continues to be a complex endeavor with prevention of associated complications, often requiring as much attention as that of the treatment of the primary injury. Paramount among these are venous thromboembolic events (VTE) due to their high incidence, additive effect on the risk of morbidity and mortality, and the careful balance that must be utilized in their diagnosis and treatment to prevent progression of the brain injury itself.
