BACKGROUND Prophylaxis for venous thromboembolism is recommended for at least 10 days after total knee arthroplasty; oral regimens could enable shorter hospital stays. We aimed to test the efficacy and safety of oral rivaroxaban for the prevention of venous thromboembolism after total knee arthroplasty. METHODS In a randomised, double-blind, phase III(More)
BACKGROUND Elective hip-replacement surgery carries significant risk of venous thromboembolism, despite use of thromboprophylaxis. We aimed to see whether the pentasaccharide fondaparinux, the first drug of a new class of synthetic antithrombotic agents, could reduce this risk to a greater extent than other available treatments. METHODS In a double-blind(More)
BACKGROUND Despite use of thromboprophylaxis, elective hip-replacement surgery carries a high risk of venous thromboembolic complications. We aimed to assess the ability of the pentasaccharide fondaparinux, the first of a new class of synthetic antithrombotic agents, to further reduce this risk. METHODS In a double-blind study, we randomly assigned 2309(More)
BACKGROUND This study sought to assess whether novel markers of hemostatic activity are predictive of coronary heart disease (CHD) and improve risk assessment. METHODS AND RESULTS Conventional CHD risk factors, the activation peptides of factor IX and factor X, factor VII activity and antigen, activated factor XII, prothrombin fragment 1+2, fibrinopeptide(More)
Venous thromboembolism is the most frequent preventable cause of death in hospitalized patients. Currently available anticoagulants have limitations that restrict their widespread use, particularly in long-term indications. Vitamin K antagonists require frequent monitoring and dose adjustment, and have a narrow therapeutic window with the risk of bleeding.(More)
During pregnancy, women have a 4- to 5-fold increased risk of thromboembolism. Candidates for anticoagulation in pregnancy include women with current thrombosis, a history of thrombosis, risk factors for postpartum thrombosis, and some women with thrombophilia and a history of poor pregnancy outcome. Although, there are no large trials of anticoagulants in(More)
OBJECTIVES To evaluate the risk of venous thromboembolic events associated with the use of progestin-only contraception and whether that risk differs with the mode of drug delivery (oral, intrauterine, or depot injection). DESIGN Systematic review and meta-analysis of randomised controlled trials and observational studies. DATA SOURCES Pubmed, Embase,(More)
BACKGROUND The association between hemostatic activation, stroke mechanism, and outcome is poorly defined. The Hemostatic System Activation Study (HAS) investigators measured serial levels of prothrombin fragment F1.2, a marker of thrombin generation, in patients enrolled in the Warfarin Aspirin Recurrent Stroke Study (WARSS). METHODS HAS enrolled 631 of(More)
Currently, in vitro synergy with colistin has not translated into improved clinical outcomes. This study aimed to compare colistin combination therapy to colistin monotherapy in critically ill patients with multi-drug resistant gram-negative (MDR-GN) pneumonia. This was a retrospective analysis of critically ill adult patients receiving intravenous colistin(More)
