BACKGROUND Patients who have had major trauma are at very high risk for venous thromboembolism if they do not receive thromboprophylaxis. We compared low-dose heparin and a low-molecular-weight heparin with regard to efficacy and safety in a randomized clinical trial in patients with trauma. METHODS Consecutive adult patients admitted to a trauma center who had Injury Severity Scores of at le...

BACKGROUND Cardiovascular disease is the leading cause of death, and multiple medications are often needed to control symptoms and risk factors. Little research has explored the cost of medications for a typical patient with chronic ischemic heart disease. We undertook a study to determine the cost of medications and how they are paid for by patients in one rural clinic. METHODS One hundred f...

Due to resource constraint of WSNs, it may be unnecessary or impossible to provide full coverage in many applications. Instead, partial coverage is enough to satisfy user requirements. Meanwhile, by applying partial coverage, network lifetime can be prolonged remarkably which is a primary goal of WSNs. In this paper, we investigate the pPercent Coverage Problem which only requires that p% of th...
