in a randomized, double blind study , we compared post operative pain and analgesic requirement in patients undergoing cesarean section with two types of general anesthesia: standardized general anesthesia (control group=26 cases) and preemptive low-dose ketamine (0.2 mg/kg) administered prior to anesthesia induction (keratmine group=27 cases). postoperative analgesia was provided for both grou...

BACKGROUND Ethanol lock therapy (ELT) with systemic antimicrobial therapy is a promising therapy for catheter-related infection (CRI). The impact of ELT timing on treatment efficacy and costs is unknown. PROCEDURES A prospective study was conducted in the Hematology/Oncology Unit at the Children's Hospital of Michigan. Patients with suspected CRI were randomized to Preemptive ELT arm or Rescu...

This paper considers a real-time status update system in which an energy harvesting (EH)-powered transmitter node observes some physical process, and sends its sensed measurements the form of status updates to destination node. The harvested packets are assumed arrive at according independent P...

BACKGROUND/AIMS Hepatic damage during transarterial chemoembolization (TACE) is a critical complication in patients with hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC). Apart from its role in preventing HBV reactivation, there is some evidence for the benefits of preemptive antiviral therapy in TACE. This study evaluated the effect of preemptive antiviral therapy on acute hepati...

Preemptive Systems are systems whose tasks are timely constrained and which can be suspended for a while and resumed afterwards. In order to check for their reliability, formal methods are applied to model and to analyze their behaviors. This is achieved by computing their state spaces that can be abstracted and encoded as graphs. We present in this paper an algorithm allowing an efficient comp...
