BACKGROUND Recent evidence suggests that preemptive use of an intra-aortic balloon pump (IABP) is associated with better outcomes in high-risk patients undergoing cardiac surgery. This retrospective study compares preemptive (planned) use of the IABP to emergency (unplanned) use in a regional cardiothoracic center. METHODS All patients who required an IABP from February 2003 to June 2006 were...

Due to their potential to deliver increased performance over single-core processors, multi-core processors have become mainstream in processor design. Computation-intensive real-time systems must exploit intra-task parallelism to take full advantage of multi-core processing. However, existing results in real-time scheduling of parallel tasks focus on restrictive task models such as the synchron...

THE concept of preemptive analgesia to reduce the magnitude and duration of postoperative pain was paved in 1983 by Woolf, who showed evidence for a central component of postinjury pain hypersensitivity in experimental studies. Subsequently, an overwhelming amount of experimental data demonstrated that various antinociceptive techniques applied before injury were more effective in reducing the ...

Guaranteeing quality for differentiated services while ensuring resource efficiency is an important and yet challenging problem in large computing clusters. Priority scheduling is commonly adopted in production systems to minimize the response time of high-priority workload by means of preempting the execution of low-priority workload when faced with limited resources. As a result, the system p...

OBJECTIVES Cytomegalovirus (CMV) infections in liver transplant recipients are common and result in significant morbidity and mortality. Intravenous ganciclovir or oral valganciclovir are the standard treatment for CMV infection. The present study investigates the efficacy of oral valganciclovir in CMV infection as a preemptive treatment after liver transplantation. METHODS Between 2012 and 2...

Sustainable vascular or peritoneal access for dialysis is very important patients undergoing therapy, and trouble occasionally involved with unexpected occurrence of complications. Once occurs, therapy might be discontinued followed by a life-threatening state end-stage kidney disease. Bacterial infection, massive bleeding, thrombosis in hemodialysis acute infectious peritonitis chronic encapsu...

Modern GPUs are broadly adopted in many multitasking environments, including data centers and smartphones. However, the current support for the scheduling of multiple GPU kernels (from different applications) is limited, forming a major barrier for GPU to meet many practical needs. This work for the first time demonstrates that on existing GPUs, efficient preemptive scheduling of GPU kernels is...

This report deals with the analysis of the performance of different versions of the wide spread Transport Control Protocol (TCP) over 3G UMTS networks. This analysis is done through simulations executed on the Network Simulator version 2 (NS2) and its Enhanced UMTS Radio Access Network Extension (EURANE). Different tool enhancements were developed in order to make this project possible. This pa...

Pain, which is often inadequately treated, accompanies the more than 23 million surgical procedures performed each year and may persist long after tissue heals. Preemptive analgesia, an evolving clinical concept, involves the introduction of an analgesic regimen before the onset of noxious stimuli, with the goal of preventing sensitization of the nervous system to subsequent stimuli that could ...
