Filter by:The purpose of this study is to evaluate the physiological consequences of extreme military training and determine whether protein supplementation enhances recovery by promoting gains in lean body mass. This study will be conducted at the US Marine Survive, Evade, Resist, Escape (SERE) school at Camp Lejeune, North Carolina. SERE school may be an ideal setting to assess nutritional interventions that promote recovery from severe military operational stress, and identify innate or experiential variables that may lead to increased levels of resilience in Warfighters. Our laboratory has recently demonstrated the detrimental effects and stressful nature of SERE. Heart rates and stress-related hormones increased dramatically, with concomitant reductions in circulating anabolic hormones. Additionally, SERE causes significant weight loss (15-20 lbs), which probably included lean body mass. The effects of severe operational stress induced by SERE, particularly the loss of lean mass, may degrade physical performance, increase injury risk, and compromise military readiness. Under controlled laboratory conditions, consuming high protein diets or supplemental high-quality protein promotes muscle protein retention, enhances muscle protein synthesis, and protects lean body mass in response to stress. Whether consuming supplemental protein promotes lean mass recovery and physiological resilience following a 'real-world' military stress has not been determined. Further, the level of supplemental protein necessary to optimize recovery from extreme military operational stress has not been elucidated. Up to 90 US Marines will be enrolled in a 46-day double-blind, placebo-controlled trial. Using complex body composition measurements, kinetic modeling of human metabolism, blood sampling and cognitive and nutrition questionnaires, the consequences of SERE and the efficacy of protein recovery nutrition on lean mass accretion and Warfighter resilience will be assessed. We hypothesize that consuming a specially formulated, high-quality supplemental protein ration item will speed recovery of lean body mass, physiological, and psychological resilience following extreme military operational stress.
An increasing number of patients survive critical illness and intensive care, but describe having impaired physical function several years after discharge as a consequence of extensive loss of muscle mass. Reasons for loss of muscle mass and physical function are multiple, but insufficient nutrition is likely to contribute. This randomised trial will investigate the effect of an optimised nutrition therapy during intensive care, on short term clinical outcome and physical quality of life. We hypothesise, that early nutritional therapy, directed towards patient-specific goals for energy and protein requirements, will improve both short- and long-term outcomes.
The purpose of this study is to determine if the investigational drug GTx-024 can help patients with non small cell lung cancer increase physical function and maintain or gain muscle.
The purpose of this study is to determine if the investigational drug GTx-024 can help subjects with non-small cell lung cancer increase physical function and maintain or gain muscle, also called "lean body mass".
The primary hypothesis for this study is that Myostatin and FHL-1 are important in the development of ICUAP and that changes in activity levels of muscle will modify the levels of expression and activity of these proteins.
