BackgroundTrained medical interpreters are instrumental to patient satisfaction and quality of care. They are especially important in student-run clinics, where many patients have limited English proficiency. Because student-run clinics have ties to their medical schools, they have access to bilingual students who may volunteer to interpret, but are not necessarily formally trained.MethodsTo study the feasibility and efficacy of leveraging medical student volunteers to improve interpretation services, we performed a pilot study at the student-run clinic at the Icahn School of Medicine at Mount Sinai. In each fall semester in 2012–2015, we implemented a 6-h course providing didactic and interactive training on medical Spanish interpreting techniques and language skills to bilingual students. We then assessed the impact of the course on interpreter abilities.ResultsParticipants’ comfort levels, understanding of their roles, and understanding of terminology significantly increased after the course (p < 0.05), and these gains remained several months later (p < 0.05) and were repeated in an independent cohort. Patients and student clinicians also rated participants highly (averages above 4.5 out of 5) on these measures in real clinical encounters.ConclusionsThese findings suggest that a formal interpreter training course tailored for medical students in the setting of a student-run clinic is feasible and effective. This program for training qualified student interpreters can serve as a model for other settings where medical students serve as interpreters.Electronic supplementary materialThe online version of this article (doi:10.1186/s12909-016-0760-8) contains supplementary material, which is available to authorized users.

Although the pathophysiology of neurodegenerative diseases is distinct for each disease, considerable evidence suggests that a single manipulation, dietary restriction, is strikingly protective against a wide range of such diseases. Thus pharmacological mimetics of dietary restrictions could prove widely protective across a range of neurodegenerative diseases. The PPAR transcription complex functions to re-program gene expression in response to nutritional deprivation as well as in response to a wide variety of lipophilic compounds. In mammals there are three PPAR homologs, which dimerize with RXR homologs and recruit coactivators Pgc1-alpha and Creb-binding protein (Cbp). PPARs are currently of clinical interest mainly because PPAR activators are approved for use in humans to reduce lipidemia and to improve glucose control in Type 2 diabetic patients. However, pharmacological enhancement of the activity of the PPAR complex is neuroprotective across a wide variety of models for neuropathological processes, including stroke, Alzheimer’s disease, Parkinson’s disease, and Huntington’s disease. Conversely activity of the PPAR transcriptional complex is reduced in a variety of neuropathological processes. The main mechanisms mediating the neuroprotective effects of the PPAR transcription complex appear to be re-routing metabolism away from glucose metabolism and toward alternative subtrates, and reduction in inflammatory processes. Recent evidence suggests that the PPAR transcriptional complex may also mediate protective effects of dietary restriction on neuropathological processes. Thus this complex represents one of the most promising for the development of pharmacological treatment of neurodegenerative diseases.
