“Ximelagatran vs Low-Molecular-Weight Heparin and Warfarin for the Treatment of Deep Vein Thrombosis”“Conclusions Oral ximelagatran administered in a fixed dose without coagulation monitoring, was as effective as enoxaparin/warfarin for treatment of deep vein thrombosis with or without pulmonary embolism and showed similar, low rates of bleeding. Increased levels of liver enzymes in 9.6% of ximelagatran-treated patients require regular monitoring; the mechanism requires further evaluation. Prospective assessment of coronary events in future studies is warranted. http://jama.ama-assn.org/cgi/content/abstract/293/6/681
“Ximelagatran vs Warfarin for Stroke Prevention in Patients With Nonvalvular Atrial Fibrillation” “Conclusions The results establish the efficacy of fixed-dose oral ximelagatran without coagulation monitoring compared with well-controlled warfarin for prevention of thromboembolism in patients with atrial fibrillation requiring chronic anticoagulant therapy, but the potential for hepatotoxicity requires further investigation” http://jama.ama-assn.org/cgi/content/abstract/293/6/690

Abu Ghraib: its legacy for military medicine

Steven H. Miles “The complicity of US military medical personnel during abuses of detainees in Iraq, Afghanistan, and Guantanamo Bay is of great importance to human rights, medical ethics, and military medicine. Government documents show that the US military medical system failed to protect detainees' human rights, sometimes collaborated with interrogators or abusive guards, and failed to properly report injuries or deaths caused by beatings.” http://www.thelancet.com/journal/vol364/iss9435/full/llan.364.9435.review_and_opinion.30574.1
AHA 2002 Fish Oil Recommendations Still Get Little Attention: “Fish oils in heart cells can block dangerous heart rhythms” (5/03)“The first clinical suggestion that n-3 PUFAs significantly benefited the heart came from a 1989 study in which 2,033 men with heart disease were given dietary advice on fat, fiber or fish. After two years the men who were told to eat fish at least twice a week had a 29 percent reduction in death. SEE LINK BELOW

A total of 302 experimental and 303 control group subjects were randomized into the study; however, the study was stopped early because of significant beneficial effects noted in the original cohort. Despite a similar coronary risk factor profile (plasma lipids and lipoproteins, systolic and diastolic blood pressure, body mass index, and smoking status), subjects following the Mediterranean-style diet had a 50% to 70% lower risk of recurrent heart disease, as measured by 3 different combinations of outcome measures including (1) cardiac death and nonfatal heart attacks; (2) the preceding plus unstable angina, stroke, heart failure, and pulmonary or peripheral embolism; and (3) all of these measures plus events that required hospitalization”. http://circ.ahajournals.org/cgi/content/full/103/13/1823
