Online Medical Control for EMS: A Lecture and Case-Based Teaching Module.

Introduction: The provision of real-time medical direction to emergency medical services (EMS) providers is a core skill for the emergency physician, yet it is one with a wide variability of training received within residency.

Methods: We developed a complete training module for providing online medical control to EMS providers, including two lectures, multiple case-based scenarios for practice via two-way radio, a survey of participants' self-perceived knowledge and comfort in this area, and a postmodule knowledge test. Participants completed the survey both before and after the module.

Acute Alcohol Use and Injury Patterns in Young Adult Prehospital Patients.

The objective was to determine if acute alcohol consumption is associated with differences in injury pattern among young adult patients with traumatic injuries presenting to emergency medical services (EMS). A cross-sectional, retrospective review of prehospital patient care reports (PCRs) was conducted evaluating injured patients who presented to a collegiate EMS agency from January 1, 2011 to December 31, 2012. Included patients were age 18-24 y and sustained an injury within the previous 24 h.

Functional characterization of kurtz, a Drosophila non-visual arrestin, reveals conservation of GPCR desensitization mechanisms.

The arrestins are a family of molecules that terminate signaling from many different G protein-coupled receptors, by inhibiting the association between receptor and downstream effectors. We recently employed a human betaarrestin2-GFP fusion protein to explore the dynamics of different neuropeptide receptors in Drosophila and have previously used a betaarrestin translocation assay to identify ligands at orphan receptors. Here, we report that the Drosophila arrestin encoded by kurtz functions in a similar fashion and can be employed to investigate GPCR-arrestin associations.
