Randomized Controlled Trial Multicenter Study Clinical Trial
Physical exercise and the prevention of disability in activities of daily living in older persons with osteoarthritis.
The prevention of disability in activities of daily living (ADL) may prolong older persons' autonomy (older persons are defined in this study as those aged > or =60 years). However, proved preventive strategies for ADL disability are lacking. A sedentary lifestyle is an important cause of disability. This study examines whether an exercise program can prevent ADL disability. ⋯ Aerobic and resistance exercise may reduce the incidence of ADL disability in older persons with knee osteoarthritis. Exercise may be an effective strategy for preventing ADL disability and, consequently, may prolong older persons' autonomy.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Comparison of the oral direct thrombin inhibitor ximelagatran with enoxaparin as prophylaxis against venous thromboembolism after total knee replacement: a phase 2 dose-finding study.
Up to one third of patients who undergo total knee replacement develop deep vein thrombosis after surgery despite receiving low-molecular-weight heparin prophylaxis. Ximelagatran is a novel direct inhibitor of free and clot-bound thrombin. ⋯ Fixed-dose, unmonitored ximelagatran, 24 mg twice daily, given after surgery appears to be safe and effective oral prophylaxis against venous thromboembolism after total knee replacement.

Randomized Controlled Trial Comparative Study Clinical Trial
Effect of maximal daily doses of acetaminophen on the liver of alcoholic patients: a randomized, double-blind, placebo-controlled trial.
Retrospective reports suggest that therapeutic doses of acetaminophen may be associated with fulminant hepatic failure and death in alcoholic patients. Millions of patients use acetaminophen; the prevalence of alcoholism in the United States is 5% to 10%. ⋯ Repeated administration of the maximum recommended daily doses of acetaminophen to long-term alcoholic patients was not associated with evidence of liver injury.
