Muscle Atrophy Clinical Trial
Official title:
MEND Repair & Recover Clinical Trial
This trial will evaluate the impact of 6 weeks of postoperative essential amino acid (EAA)-based supplementation on muscle morphology after femoral fragility fracture. This trial will assess the ability of EAA-based to increase skeletal muscle metabolic activity, reduce inflammation, and induce muscle fiber hypertrophy, as well as preserve skeletal muscle mass and physical performance up to 6 months after injury. Participants will be randomized in a 1:1 ratio to 1) standard of care (no dietary intervention) or 2) EAA-based supplementation.

---|---|---|---|---|
Primary | Concentration and average count of satellite cells, myonuclei, M1, and M2 Macrophages for Type 1 and Type 2 fibers | Biopsy results will provide the counts and averages by Type I and Type II fibers for satellite cells, myonuclei, M1 and M2 macrophages. | Day of Surgery, 3 weeks | |
Primary | Cross sectional concentration of Type 1 and Type 2 muscle fibers | Biopsy results will provide the Type I and Type II muscle fiber cross sectional area in µm2. | Day of Surgery, 3 weeks | |
Primary | Concentration of myostatin, interleukin-6, and tumor necrosis factor alpha | Through serum analysis levels of myostatin, interleukin-6 (IL-6), and tumor necrosis factor alpha (TNF-a) will be measured in pg/mL. | Day of Surgery, 3 weeks | |
Primary | Concentration of c-terminal agrin fragments | Through serum analysis levels of c-terminal agrin fragment will be measured in ng/mL. | Day of Surgery, 3 weeks | |
Secondary | Change in skeletal muscle | Change in the amount of skeletal muscle mass will be measured by the InBody S10 Body Composition Analyzer and recorded in kilograms. | Day of Surgery, 3 weeks, 6 weeks, 12 weeks, 6 months | |
Secondary | Measurement of lower extremity functioning in older adults | Physical performance in relation to lower extremity function will be measured by the Short Physical Performance Battery (SPPB) 14. Individuals are scored on a scale ranging from 0 (worst performance) to 12 (best performance) based on their walking speed, ability to do chair stands, and standing balance. | 12 weeks, 6 months | |
Secondary | Assessment of mobility, balance, walking ability, and fall risk in older adults | Physical performance in relation to mobility, balance, walking ability and fall risk will be measured by the Timed Up & Go (TUG) 15 test. For this test, the research coordinator measures the time required for a participant to rise from an armchair (45 cm height), walk 3 m and return to the chair. Longer times can indicate higher possibility of falling. | 12 weeks, 6 months | |
Secondary | Measurement of self-reported physical capability | Patient-reported physical performance will be measured using the PROMIS-Physical Function survey. PROMIS measures are scored on the T-score metric. a high score means the individual self-reports more of a capability at a certain activity. | Day of Surgery, 3 weeks, 6 weeks, 12 weeks, 6 months | |
Secondary | Measurement of self-reported ability to complete activities of daily living (ADL) | Patient-reported physical performance of activities of daily living will be measured using the Barthel Activities of Daily Living Index. It is a commonly used measure of activities of daily living outcomes for older adults. It measures the ability to perform activities of daily living that are important for maintaining function including feeding, bathing, grooming, dressing, bowel control, bladder control, toilet use, transfers from bed to chair and back, mobility on level surfaces, and stairs. Each measure is assessed on a 10-point scale, all scores are combined to give a score out of 100 points. The higher the score the more independent the individual. | 12 weeks, 6 months | |
Secondary | Assessment of independent or communal living | Residence at a nursing home or living independently will be recorded at each follow-up visit. Participants living in an assisted living home (apartment or condominium with nursing assistance on call), apartment, single family home, or family member's home are considered living in the community. Living without assistance in a single dwelling will be considered living independently. | 12 weeks, 6 months |
