Team-based learning in the internal medicine clerkship didactics.

Background: Active-learning approaches, such as team-based learning, are infrequently used in internal medicine clerkship didactics even though there is increasing evidence to suggest medical students prefer it over traditional lecture-based learning. In this study, five team-based learning sessions were incorporated into three blocks of a 12-week internal medicine clerkship.

Methods: The goal of this quasi-experimental study was to compare learner engagement, satisfaction and preference between team-based learning and lecture-based learning in the internal medicine clerkship didactics.

Neonatal Intensive Care Unit Mixed Lipid Emulsion Use Associated With Reduced Cholestasis at Discharge in Surgical Patients.

Introduction: Parenteral nutrition associated cholestasis (PNAC) is a common morbidity in neonates requiring total parenteral nutrition (TPN). Previous studies in infants with intestinal failure have shown a benefit of mixed lipid emulsion (MLE) in reducing PNAC. It is not known whether this benefit extends to a general neonatal intensive care unit (NICU) population, where MLE is used on a selective basis.

Ammonite habitat revealed via isotopic composition and comparisons with co-occurring benthic and planktonic organisms.

Ammonites are among the best-known fossils of the Phanerozoic, yet their habitat is poorly understood. Three common ammonite families (Baculitidae, Scaphitidae, and Sphenodiscidae) co-occur with well-preserved planktonic and benthic organisms at the type locality of the upper Maastrichtian Owl Creek Formation, offering an excellent opportunity to constrain their depth habitats through isotopic comparisons among taxa. Based on sedimentary evidence and the micro- and macrofauna at this site, we infer that the 9-m-thick sequence was deposited at a paleodepth of 70-150 m.
