497. Using Ultrasound to Assess Body Composition

Tuesday, October 23
9:45 AM - 11:15 AM
CE: 1.5

Session Level 3 - Advanced

Skeletal muscle mass is responsible for functional independence and normal metabolism while adipose tissue is associated with various chronic diseases. Total and the ratio of muscle mass and adipose tissue influence energy expenditure, glucose uptake, glycogen storage and fatty acid oxidation. Additionally, muscle tissue provides a reservoir of amino acids that can be used for synthesis of antibodies, enzymes, and cell signaling molecules. Changes in muscle mass and adipose tissue can significantly alter physiological and physical function, so accurate measurements of muscle mass and adipose tissue are important to determine nutrition and exercise interventions that maintain normal metabolism, preserve immune function and sustain functional independence. This session will summarize the importance of muscle mass and adipose tissue to health and response to disease, as well as the opportunities and challenges of using ultrasound for the nutrition assessment of various patient populations.

Yimin Chen, PhD, RD, CNSC

Dr. Yimin Chen has been a practicing nutrition support dietitian for 15 years and has recently transitioned to a translational human milk researcher. She started her research career primarily in adult nutrition support clinical studies before switching gear to neonatology and human milk research during her PhD work in basic science research. Dr. Chen is a research collaborator with the Rush NICU Human Milk Research Program. Her research interest focuses on specific human milk components and how manipulations of human milk feedings affect cellular and intestinal response in premature infants.

Marina Mourtzakis, PhD

Marina Mourtzakis is an Associate Professor and Associate Chair of Applied Research, Partnerships and Outreach in the Department of Kinesiology at the University of Waterloo. Her research program has several objectives: 1) to integrate nutrition, exercise and protein metabolism to understand body composition changes in cancer and critical illness, 2) to explore and advance the use of ultrasound computed tomography in characterizing skeletal muscle in clinical populations, 3) to understand the role of specific amino acids in muscle health, and 4) to optimize muscle health in clinical populations with nutrition and exercise.
