BACKGROUND Tranexamic acid can reduce bleeding in patients undergoing elective surgery. We assessed the effects of early administration of a short course of tranexamic acid on death, vascular occlusive events, and the receipt of blood transfusion in trauma patients. METHODS This randomised controlled trial was undertaken in 274 hospitals in 40 countries.(More)
MRC CRASH is a randomised controlled trial (ISRCTN74459797) of the effect of corticosteroids on death and disability after head injury. We randomly allocated 10,008 adults with head injury and a Glasgow Coma Scale score of 14 or less, within 8 h of injury, to a 48-h infusion of corticosteroid (methylprednisolone) or placebo. Data at 6 months were obtained(More)
Serology for hepatitis B and C markers was performed on a community-based random sample of 506 residents of an area recently reclaimed from the desert and endemic for Schistosoma mansoni. The mean age of the study subjects was (20 +/- 14), and 52% were males. The overall seroprevalence of hepatitis B (Anti-HBc and/or HBsAg) was 19.6%, hepatitis C (Anti-HCV)(More)
Reclamation of land from the desert is currently taking place in all parts of Egypt. A side-effect of many of these projects has been the introduction of schistosome parasites and their snail intermediate hosts, sometimes among Bedouin population with no previous exposure to the disease. The purpose of the present study was to describe social, environmental(More)

Wireless sensor networks (WSN) have the potential of significantly enhancing our ability to monitor and interact with our physical environment. Realizing a fault-tolerant operation is critical to the success of WSN. The main challenge is providing fault-tolerance (FT) while conserving the limited resources of the network. Our main contribution in this paper(More)
