An Interprofessional Nutrition Education Session for Senior Medical Students on Evidence-Based Diet Patterns and Practical Nutrition Tips.

Introduction: Dietary factors are recognized as a major contributor to the global burden of disease, and the obesity epidemic continues to be a major public health problem. Patients rely on doctors for dietary advice and to serve as role models for health behaviors. However, nutrition content is significantly underrepresented in medical school curricula. Methods: We created an interactive session to address this gap during the ambulatory medicine rotation for senior medical students and delivered it as a 90- to 120-minute interactive monthly didactic session. We focused on reviewing evidence-based diet patterns for weight loss and hypertension and on use of practical tools for diet assessment and counseling. Immediately and 1 month after delivery, we administered a knowledge and confidence assessment survey to evaluate the session impact. Results: We incorporated the session into the regular didactic time of the clerkship. Sixty-six students attended over an 8-month period, of whom 42 completed the survey. Immediately and 1 month after delivery, participants reported statistically significant improvements (p < .001) in their confidence in the domains measured. Participants' knowledge scores increased immediately and 1 month after the session compared to before participation. Discussion: We delivered a single recurring seminar on diet patterns and practical tips that was well received by fourth-year medical students during the ambulatory medicine clerkship. The seminar was a practical and interactive way of delivering important nutrition content to the medical school curriculum, and we demonstrated retention of confidence and knowledge of the delivered content.

Glutamine supplementation in infants with gastrointestinal disease: a randomized, placebo-controlled pilot trial.

OBJECTIVE: Glutamine (Gln) is a non-essential amino acid that plays an important role in energy metabolism for gastrointestinal epithelia and other cells with rapid turnover. We evaluated the effects of enteral supplementation with Gln in infants undergoing surgery for congenital or acquired gastrointestinal disease. METHODS: This was a randomized, double-masked, controlled clinical trial. RESULTS: Twenty infants were randomly assigned to receive Gln (n = 9) or placebo amino acid (n = 11), with a goal of supplemental amino acid intake of 0.4 g.kg(-1).d(-1). Infants were weaned from parenteral nutrition, and enteral feeds were started according to a standardized feeding protocol. Median (interquartile range) durations of parenteral nutrition were 39 d (12 to 99) in the Gln group and 21 d (6 to 59) in the control group (P = 0.201). Median (interquartile range) durations needed to reach 80% of the US recommended dietary allowance for energy with enteral nutrition were 24 d (8 to 55) in the Gln group and 12.5 d (5 to 32) in the control group (P = 0.313). There were no differences in the occurrence of infections between groups. Among all infants enrolled, significant correlations were found between duration of parenteral nutrition and residual small bowel length, peak concentrations of direct bilirubin, and alanine aminotransferase. Peak direct bilirubin was associated with longer duration of parenteral nutrition, shorter gestation, older age before feeds were started, shorter bowel length, and larger amounts of parenteral energy and protein intake. CONCLUSIONS: In this pilot trial, enteral Gln supplementation was well tolerated among infants with surgical gastrointestinal disease. There was no effect observed on the duration of parenteral nutrition, tolerance of enteral feeds, or intestinal absorptive or barrier function. Larger, multicenter trials in infants with surgical gastrointestinal disease are needed due to the variability in important outcome measurements.
