Intravenous esomeprazole for prevention of recurrent peptic ulcer bleeding: a randomized trial.
Use of proton-pump inhibitors in the management of peptic ulcer bleeding is controversial because discrepant results have been reported in different ethnic groups. ⋯ AstraZeneca Research and Development.

Impact of age and comorbidity on colorectal cancer screening among older veterans.
The Veterans Health Administration, the American Cancer Society, and the American Geriatrics Society recommend colorectal cancer screening for older adults unless they are unlikely to live 5 years or have significant comorbidity that would preclude treatment. ⋯ Advancing age was inversely associated with colorectal cancer screening, whereas comorbidity was a weaker predictor. More attention to comorbidity is needed to better target screening to older patients with substantial life expectancies and avoid screening older patients with limited life expectancies. primary funding source: VA Health Services Research and Development.

Oral vitamin K versus placebo to correct excessive anticoagulation in patients receiving warfarin: a randomized trial.
Low-dose oral vitamin K decreases the international normalized ratio (INR) in overanticoagulated patients who receive warfarin therapy. Its effects on bleeding events are uncertain. ⋯ Canadian Institutes of Health Research and Italian Ministry of Universities and Research.
