Question: Abstract: PURPOSE Anticoagulant prophylaxis in patients with central venous catheters is controversial. We performed a meta-analysis of randomized controlled trials of anticoagulant prophylaxis in patients with central venous catheters.
METHODS MEDLINE and EMBASE were searched up to May 2006, supplemented by manual searches of conference proceedings and bibliographies.
RESULTS Fifteen trials were included. Unfractionated heparin infusion, oral fixed low-dose vitamin K antagonist, and subcutaneous low-molecular-weight heparin were evaluated. For all catheter-associated deep vein thrombosis (symptomatic and asymptomatic combined), the summary relative risks ranged from 0.31 to 0.73 (all achieved statistical significance). For symptomatic deep vein thrombosis, the summary relative risks ranged from 0.28 to 0.72, but did not achieve statistical significance for any individual regimen.
CONCLUSION Anticoagulant prophylaxis is effective for preventing all catheter-associated deep vein thrombosis in patients with central venous catheters. The effectiveness for preventing symptomatic venous thromboembolism, including pulmonary embolism, remains uncertain..

Question: Abstract: We explored the emerging relationships among the alcohol industry, academic medicine, and the public health community in the context of public health theory dealing with corporate social responsibility. We reviewed sponsorship of scientific research, efforts to influence public perceptions of research, dissemination of scientific information, and industry-funded policy initiatives. To the extent that the scientific evidence supports the reduction of alcohol consumption through regulatory and legal measures, the academic community has come into increasing conflict with the views of the alcohol industry. We concluded that the alcohol industry has intensified its scientific and policy-related activities under the general framework of corporate social responsibility initiatives, most of which can be described as instrumental to the industry's economic interests..
