Identify predictors of cardiogenic etiology among emergency department (ED) patients with hypotension, and use these predictors to create a clinical tool to discern cardiogenic etiology of hypotension. ⋯ Clinical predictors offer reasonable ED screening sensitivity for cardiogenic hypotension, while demonstrating sufficient specificity to facilitate early cardiac interventions.

Needlestick injury prevalence, protection practices, and attitudes were assessed. Current medical students were compared with 2003 data to assess any changes that occurred with engineered safety feature implementation. ⋯ Needlestick injury and occupational exposure to bloodborne pathogens are significant hazards for surgeons and nurses. Attitudes regarding risk are changing, and the true seroconversion risk is underestimated. Educational efforts focused on needlestick injury prevalence, seroconversion rates, and double-glove perforation rates may be effective in implementing protective strategies.

To evaluate whether advanced age increases the risk of severe complications after major hepatectomy with bile duct resection (BDR) in patients with biliary tract cancer, and to establish new criteria for the percentage of the future remnant liver volume (%FLV) in older patients undergoing this operation. ⋯ Advanced age is a strong independent risk factor for severe complications after major hepatectomy with BDR. To decrease the risk of advanced age, the minimum limit of %FLV for this operation should be set at ≥45% in patients aged ≥69 years.

To demonstrate the clinical utility of the buccal fat pad flap (BFPF) for closing a variety of skull base defects. ⋯ This is the first report on the application of endoscopic BFPF. Our experience suggests that this recently described flap is viable and a useful addition to the armamentarium of the skull base surgeon.

Perinatal exposure to ambient air pollution has been associated with childhood asthma incidence, however, less is known regarding the potential effect modifiers in this association. We examined whether maternal and infant characteristics modified the association between perinatal exposure to air pollution and development of childhood asthma.761 172 births occurring between 2006 and 2012 were identified in the province of Ontario, Canada. ⋯ Enhanced impacts were found among children born to mothers with asthma, those who smoked during pregnancy, boys, those born preterm, of low birth weight and among those born to mothers living in urban areas during pregnancy. Prenatal exposure to air pollution may have a differential impact on the risk of asthma development according to maternal and infant characteristics.
