PURPOSE A substantial clinical need exists for an alternative to vitamin K antagonists for treating deep-vein thrombosis in cancer patients who are at high risk of both recurrent venous thromboembolism and bleeding. Low-molecular-weight heparin, body-weight adjusted, avoids anticoagulant monitoring and has been shown to be more effective than(More)
BACKGROUND Based on the current understanding that venous thrombosis starts perioperatively, administration of just-in-time low-molecular-weight heparin immediately before or in close proximity after hip arthroplasty may be more effective than usual clinical practice. METHODS We performed a randomized, double-blind trial comparing subcutaneous dalteparin(More)
PURPOSE Evidence-based medicine guidelines based on venographic end points recommend in-hospital prophylaxis with low-molecular-weight heparin (LMWH) in patients having elective hip surgery. Emerging data suggest that out-of-hospital use may offer additional protection; however, uncertainty remains about the risk-benefit ratio. To provide clinicians with a(More)
BACKGROUND Perioperative and postoperative venous thrombosis are common in patients undergoing elective hip surgery. Prophylactic regimens include subcutaneous low-molecular-weight heparin 12 hours or more before or after surgery and oral anticoagulants. Recent clinical trials suggest that low-molecular-weight heparin initiated in closer proximity to(More)
BACKGROUND No randomized trials have directly evaluated the need for extended out-of-hospital thromboprophylaxis for patients who have hip arthroplasty in the United States or Canada. The uncertainty as to the need for extended prophylaxis in North American patients is complicated by early hospital discharge, resulting in a short thromboprophylaxis(More)
PURPOSE Clot-burden change in patients receiving anticoagulant therapy, by predicting subsequent recurrent venous thromboembolism, may provide a clinically relevant surrogate endpoint of prognostic importance. The validity of this objective measure is yet to be established. METHODS A PubMed search was performed to retrieve articles published up to(More)
BACKGROUND Pulmonary embolism (PE) occurs in 50% or more of patients with proximal deep-vein thrombosis. Low-molecular-weight heparin treatment is effective and safe in patients with deep vein thrombosis and may also be so in patients with PE. Recent rigorous clinical trials have established objective criteria for determining a high probability of PE by(More)
PURPOSE A substantial clinical need exists for an alternate to vitamin K antagonists for treating deep vein thrombosis in many patients. Long-term low-molecular-weight heparin (LMWH), body-weight adjusted, avoids anticoagulant monitoring and may be associated with less bleeding. We evaluated the effectiveness and safety of long-term LMWH compared with(More)
This article discusses the development, format, administration and scoring of the objective structured clinical examination (OSCE) to evaluate competency in sport medicine. The credentials committee of the Canadian Academy of Sport Medicine has developed an examination to evaluate the competency of practicing physicians in the field of sport medicine. The(More)
