Randomized Controlled Trial
Pre-operative modification of dietary glycemic index improves pre but not post-operative indices of insulin resistance in patients undergoing coronary artery bypass graft surgery.
Improving insulin sensitivity in coronary artery bypass grafting (CABG) patients may translate into improved glycemic control and postoperative outcomes. The implementation of a low glycemic index (LGI) diet in the pre-operative period may improve insulin sensitivity and subsequently impact on the development of post-operative insulin resistance. The aim of this study was to determine whether a short term LGI diet would reduce postoperative insulin resistance. ⋯ A preoperative LGI diet presents a non-invasive cardio-protective opportunity warranting clinical trial.

The majority of graduating US medical students reported inadequate nutrition training over the past decade. This trend could in part be due to the lack of valid measures to assess the relationship between adequacy of nutrition training and proficiency on nutrition topics deemed essential. The study's objective was to test the hypothesis that self-reported nutrition proficiency is positively correlated with the perceived adequacy (quality, quantity, coverage and importance) of nutrition training of University of Washington medical students. ⋯ Quality and coverage may be effective gauges of adequacy of nutrition training and related nutrition proficiency in medical education. Current national medical education evaluation measures focus on the quantity of nutrition instruction. The lowest reported proficiency topics; nutrition and disease management, micronutrients and complementary and alternative medicine are recommended for particular curricular emphasis.
