Association of prehospital advanced airway management with neurologic outcome and survival in patients with out-of-hospital cardiac arrest.
IMPORTANCE It is unclear whether advanced airway management such as endotracheal intubation or use of supraglottic airway devices in the prehospital setting improves outcomes following… Expand
Trends in Bronchiolitis Hospitalizations in the United States, 2000–2009
OBJECTIVE: To examine temporal trend in the national incidence of bronchiolitis hospitalizations, use of mechanical ventilation, and hospital charges between 2000 and 2009. METHODS: We performed a… Expand
Regional variability in survival outcomes of out-of-hospital cardiac arrest: the All-Japan Utstein Registry.
OBJECTIVE There is a paucity of studies on the degree of regional variability in out-of-hospital cardiac arrest (OHCA) outcomes, particularly in neurological outcome. This study aimed to determine… Expand

Hepatitis B virus (HBV) mutants unable to synthesize HBV e antigen have been described in association with fulminant hepatitis. We have cloned and sequenced the entire viral genome of an HBV strain… Expand
Epidemiology of emergency department visits for opioid overdose: a population-based study.
OBJECTIVES To evaluate the rate of emergency department (ED) visits for opioid overdose and to examine whether frequent ED visits for opioid overdose are associated with more hospitalizations,… Expand

STUDY OBJECTIVE Although repeated intubation attempts are believed to contribute to patient morbidity, only limited data characterize the association between the number of emergency department (ED)… Expand
Association of nasopharyngeal microbiota profiles with bronchiolitis severity in infants hospitalised for bronchiolitis
Little is known about the relationship between the specific airway microbiota composition and severity of bronchiolitis. We aimed to identify nasopharyngeal microbiota profiles and link these… Expand

Abstract Background. We investigated whether children with a higher respiratory syncytial virus (RSV) genomic load are at a higher risk of more-severe bronchiolitis. Methods. Two multicenter… Expand
Trends in U.S. emergency department visits for opioid overdose, 1993-2010.
OBJECTIVE Emergency department (ED) visits for opioid overdose provide an important marker of acute morbidity. We sought to evaluate national trends of ED visits for opioid overdose. DESIGN,… Expand
