This pilot study aims to determine the impact of whey protein supplementation on brain antioxidant levels and to assess the effects of whey protein supplementation on physical function, body composition, and cognition in pre-frail older adults.
Frailty has been associated with poor acute and long-term outcomes after major surgery. We recently determined that nearly 70% of patients undergoing major thoracic surgery are pre-frail or frail. We are interested in assessing whether a strength training intervention for frail or pre-frail patients has an impact on surgical decision making and on surgical outcomes.
The Supporting Habit Formation to Attenuate Prefrailty in Elders (SHAPE) Pilot Study is a randomized control study. The main objective of this pilot study is to determine the feasibility of using Habit Formation (HF) treatment to increase Physical Activity (PA) (reduction in daily in hours of sedentary time), and dietary among prefrail African Americans. We hypothesize: (1)The SHAPE study will demonstrate good feasibility with a high recruitment rate and successful administration all of the measures among the target population; (2) Treatment group participants will demonstrate greater increases in primary outcomes (physical activity level and dietary quality) and secondary outcomes (quality of life, depressive symptoms, prefrailty reduction, lower extremity strength and balance, physical activity level, waist circumference, and weight at intervention completion.
The swallowing muscles are prone to decreased strength and function as part of the natural aging process which can lead to difficulty swallowing, malnutrition, and frailty. Exercise and nutrition are powerful stimulators of muscular change. The proposed research will investigate the effectiveness of a 12-week proactive regimen of swallowing exercises (with or without daily protein supplement drinks) to improve the composition, force, and physiology of the swallowing muscles and explore the relationship to overall health and physical function in 80 community-dwelling older adults. Each participant will serve as their own control for 12 weeks before being randomized to complete swallowing exercises alone or swallowing exercises with protein drinks.
This clinical trial is a Phase II study designed to test the safety and effectiveness of a combination of dasatinib and quercetin (D+Q) in improving physical function for people with HIV who are frail or prefrail. The study will involve 80 participants, all aged 50 or older, who have been living with HIV for at least 10 years determined to meet criteria for diagnosis of frail or prefrail and are currently on a stable antiretroviral therapy with viral suppression. Participants will be randomly assigned to one of two groups: one group will receive the D+Q treatment, and the other will receive a placebo. The treatment will be given in six cycles over 12 weeks, with participants taking the medication for two days followed by 12 days without treatment. After the 12-week treatment period, participants will be monitored for another 12 weeks to assess the long-term effects. The study aims to determine if D+Q can improve physical function and other health outcomes in this population. Randomization will be stratified by sex and age to ensure balanced groups.
Aim 1: To assess the feasibility and acceptability of delivering AGE SELF CARE through virtual medical group visits by measuring recruitment rate, adherence, and participant satisfaction. Hypothesis 1: It will be feasible to recruit 12 older adults who are pre-frail. Hypothesis 2: At least 70% of participants will attend 6 of 8 group visit sessions. Hypothesis 3: At least 70% of participants will report satisfaction with the program. Aim 2: Determine the feasibility and burden of measuring frailty in this study by different instruments. Hypothesis 1: At least 70% of participants will complete portions of all frailty assessments. Hypothesis 2: Participants will not find testing to be burdensome and measures may be completed in 60 minutes or less. Hypothesis 3: Mean gait speed and frailty index will improve from baseline to post-intervention.
Metformin has a well-established safety profile and it has become clear that metformin has additional salutary effects, including anti-inflammatory, anti-aging, and anti-thrombotic properties. In this study, subjects will provide both venous blood samples and stool samples in addition to completing cognitive and physiologic testing at baseline, throughout a 90 day exposure to metformin, and 30 days following exposure to metformin in order to evaluate their immune, microbiome, cellular respiration, thrombotic, and inflammatory responses.
