The synthesis of prostanoids is regulated by cyclooxygenases (prostaglandin H synthases), which catalyze the conversion of arachidonic acid to PGH2. Cyclooxygenases are the target of aspirin and other nonsteroidal anti-inflammatory agents. In this study, we found that human polymorphonuclear leukocytes (PMNs) express the inducible isoform of cyclooxygenase,(More)
OBJECTIVES To establish longitudinal validation of a new tool, the Asthma Symptom Tracker (AST). AST combines weekly use of the Asthma Control Test with a color-coded graph for visual trending. METHODS Prospective cohort study of children age 2 to 18 years admitted for asthma. Parents or children (n = 210) completed baseline AST assessments during(More)
PURPOSE To explore students' perceptions of virtual patient use in the clinical clerkship and develop a framework to evaluate effects of different integration strategies on students' satisfaction and perceptions of learning effectiveness with this innovation. METHOD A prospective, multiinstitutional study was conducted at six schools' pediatric clerkships(More)
BACKGROUND Respiratory Syncytial Virus (RSV), a major cause of bronchiolitis, has a large impact on the census of pediatric hospitals during outbreak seasons. Reliable prediction of the week these outbreaks will start, based on readily available data, could help pediatric hospitals better prepare for large outbreaks. METHODS Naïve Bayes (NB) classifier(More)
This reflection is based on the premise that clinical education can be improved by more widespread use of computer-assisted instruction (CAI) and that a roadmap will enable more medical educators to begin using CAI. The rationale for CAI use includes many of its inherent features such as incorporation of multimedia and interactivity yet the use of CAI(More)
Group B streptococcal (GBS) infections are associated with high morbidity and mortality. The molecular pathways mediating the pathophysiological events in GBS infection are not fully delineated. Cyclooxygenases (COX) are the enzymes that convert arachidonate to active eicosanoids. To identify the effects of GBS on eicosanoid metabolism and regulatory(More)
OBJECTIVE To evaluate for adverse outcomes associated with gastroesophageal reflux disease (GERD) following an apparent life-threatening event (ALTE) and potential risk factors of these outcomes. STUDY DESIGN Retrospective cohort study of well-appearing infants (<12 months) admitted for ALTE. Patients were followed for adverse outcomes associated with(More)
Hospital bed demands sometimes exceed capacity, leading to delays in patient admissions, transfers and cancellations of surgical procedures. Effective strategies must be in place for an efficient use of existing beds. Establishing such strategies at academic hospitals poses serious challenges. We developed and implemented a web-based software application(More)
BACKGROUND AND OBJECTIVE Imperfect diagnostic tools make it difficult to know the extent to which a bacterial process is contributing to respiratory illness, complicating the decision to prescribe antibiotics. We sought to quantify diagnostic and antibiotic prescribing disagreements between emergency department (ED) and pediatric hospitalist physicians for(More)
