Review Meta AnalysisDirect oral anticoagulants more effective than low-molecular-weight heparin for venous thrombo-embolism in cancer: an updated meta-analysis of randomized trials.
In the recent past, low-molecular-weight heparin (LMWH) was the first choice in the treatment of cancer related venous thrombo-embolism (VTE). Evidence supporting the preferential use of direct anticoagulants (DOACs) in patients with cancer, instead, is less robust so far. We therefore aimed to assess in an updated meta-analysis of randomized controlled trials whether the use of DOACs may be associated with a more favorable profile when compared to LMWH. ⋯ DOACs patients had a lower incidence of 6-month recurrent VTE when compared to LMWHs (RR 0.56, 95% CI 0.40-0.79; p < 0.001). Incidence of major bleeding was not significantly different between DOACs and LMWH treated patients (RR 1.56, 95% CI 0.95-2.47, p = n.s.), and mortality rates were comparable (RR 1.03, 95% CI 0.91-2.47, p = n.s.). In a meta-analysis of RCTs therapy with DOACs was superior to LMWH in terms of efficacy and lower recurrence of VTE with a comparable safety profile in terms of bleeding events and complications.

Meta AnalysisThe efficacy and safety of tranexamic acid in the treatment of intertrochanteric fracture: an updated meta-analysis of 11 randomized controlled trials.
This meta-analysis was performed to investigate the efficacy and safety of tranexamic acid (TXA) in the elderly patients undergoing intertrochanteric fracture surgery from the current literatures. The electronic literature database of PubMed, Embase and Cochrane library were searched in October 2019. The intraoperative blood loss, hidden blood loss, postoperative drainage and total blood loss, postoperative hemoglobin, length of stay, transfusion rate, mortality rate, thromboembolic events and wound complications were extracted. ⋯ However, no significant difference was found between the TXA group and control group regarding the occurrence of thromboembolic events (P = 0.978, including deep vein thrombosis, P = 0.850; pulmonary embolism, P = 0.788; cerebrovascular accident, P = 0.549; myocardial infarction, P = 0.395) and mortality rate (P = 0. 338). Our meta-analysis suggested that administration of TXA is effective in reducing intraoperative blood loss, hidden blood loss, total blood loss, length of stay, transfusion rate, wound complications and enhancing postoperative Hb without increasing the risk of thromboembolic events and mortality rate in intertrochanteric fracture surgery. More large multi-center and high-quality RCTs are required for further research.
