Safe-Age Study: A Safety and Tolerability Study of a Nutritional Supplement in Healthy Older Adults

The goal of this clinical trial is to evaluate the safety and tolerability of the nutritional supplement Youniqor in healthy older adults. The main questions it aims to answer are: Is Youniqor safe and well tolerated when taken daily by healthy adults aged 60 to 80 years? Are there any adverse events or clinically relevant changes in vital signs or laboratory parameters during the study period? Participants will: Take Youniqor daily for 8 weeks Attend scheduled study visits for safety assessments, including vital signs, blood and urine tests, and electrocardiograms Report any adverse events during the study period

Emotional Well-being and Measures of Healthy Aging

This randomized control study is designed to understand the role of a positive psychology intervention (PARK: Positive Affect Regulation sKills) in biological aging and well-being. PARK provides a series of positive emotion skills in a self-guided online format, making the program accessible and convenient. Our main aims are: Aim 1: To explore the effects of PARK on psychological well-being (e.g., depression, anxiety, positive affect). Aim 2: To explore the effects of PARK on biological age as defined by DNA methylation (DNAm) GrimAge and electrocardiogram-age (ECG-age), as well as physiological well-being in adults (e.g., cardiovascular, endocrine, musculoskeletal functioning, etc.).

Circadian Health Regulation and Optimization for Rejuvenation Outcomes

In this single arm intervention trial, the investigators will assess the impact of a personalized lifestyle plan, centered on supporting biological rhythms, on blood sugar levels, physical, cognitive and immune function in older adults with a habitual eating window of 12 hours or more, and elevated blood glucose levels. All participants will be provided with a personalized circadian rhythm optimization plan (CRO) centered on improving (1) diet, (2) exercise (3) sleep habits based on their body's natural rhythms. The study includes a 2-week screening/baseline assessments, with follow-up health assessments at 2-months.

Neuromuscular Electrical Stimulation and Action Observation for Healthy Aging

Aging is associated with a decline in muscle strength and the functionality of the perceptual structures involved in proprioception. This decline results in a gradual loss of autonomy in daily activities. Neuromuscular electrical stimulation (NMES) has been shown to be an effective technique in limiting the decline in strength. Action observation (AO) is a cognitive technique, which has been shown to improve motor performance, especially when combined with peripheral stimulation. The purpose of this study is to evaluate whether a self-administered, home-based intervention combining NMES and AO improves upper limb muscle strength and proprioceptive abilities in healthy elderly individuals. Participants within the age range of 65-85 years will be recruited for this study. The intervention is scheduled to span a duration of four weeks, encompassing three treatment sessions per week. Participants will be randomly divided into three groups: NMES, AO, and AO-NMES. Assessments will be performed before and immediately after the intervention. They will include muscle strength evaluation (handgrip strength, maximal isometric force of the biceps, bench press power), and perceptual evaluation (weight discrimination during an AO task, weight judgment tasks). This study may suggest an original approach, cost-effective approach to mitigate the effects of physiological aging on muscle and sensorimotor function, with potential applications for frail populations, unable or unmotivated to perform conventional physical activity.

Evaluation of the Effect of Seasonality on Biological Age in Adults

This research aims to provide insights on how seasonal variations influence biological age and enhance the design and analysis of long-term lifestyle interventions targeting biological clocks. Aging is a gradual decline in cellular and organ functions, significantly increasing the risk of non-communicable and infectious diseases. Recent research has focused on identifying aging biomarkers that can better predict functional capability in healthy individuals. Biological age clocks, which can be measured from samples like blood or saliva, are emerging as valuable tools for assessing the pace of aging and calculating age acceleration-the difference between chronological and biological age. These clocks utilize molecular and clinical data, including DNA methylation and plasma proteomics, to predict future health outcomes, such as disease risk and mortality. Various DNA methylation-based clocks have been developed, with the Dunedin Pace of Aging (PoAm) offering a more precise modeling of physiological changes over time. Lifestyle factors, including diet and physical activity, can influence age acceleration, suggesting that lifestyle interventions may impact biological aging. Current evidence indicates that three specific epigenetic clocks-PhenoAge, GrimAge, and Dunedin PACE-are particularly effective in detecting beneficial effects on aging trajectories. However, the stability of these clocks during long-term lifestyle interventions remains unclear, as they can exhibit variability over short periods and may be affected by factors influenced by seasonal changes, such as Vitamin D levels, climate, and white blood cells composition. To investigate these seasonal effects on biological age, a proposed observational study will track changes over a 12-month period in middle-aged and older adults.

Study of Healthy Aging and Physical Function With Elamipretide

This study will utilize a daily dose of elamipetide for 4 weeks and will screen a sufficient number of subjects for 30 subjects to enroll in the study. The planned duration of the study includes baseline measurement, followed by 4 weeks intervention period, a midpoint (2week ±3days) check-in phone interview, and post intervention visits that mirror the baseline visits. After the last injection, subjects will enter the 2-week follow-up period, concluded by the end-of-study contact.

Personalized Approach to Promote Healthy Aging

The goal of this clinical trial study is to evaluate the impact of a personalized lifestyle intervention on improving healthspan. The primary questions of interest are whether the personalized intervention will result in improvements in muscle function, immune function, and cognitive function in adults aged 50-85 years. Participants will complete baseline assessments, receive an individualized intervention plan for approximately 3 months, and then complete post-intervention assessments. The intervention includes an exercise plan, nutrition recommendations, and general lifestyle goals that will be personalized to each participant.

Physical and Cognitive Aging Study in Older Adults

Hispanic Americans are the fastest growing older adult group in the United States, disproportionally increasing the risk of an Alzheimer's disease and related dementias diagnosis. Efforts to reduce this risk and mitigate the related cognitive/physical declines are critical. The aim of this study is to assess the feasibility of enrolling older adults into an aging trajectory cohort, while generating preliminary data on associations of physical and cognitive aging trajectories. Our secondary objective is to generate preliminary data on the association of standard measures of physical activity and physical function with cognitive status. This study fits within our longitudinal research goal to reduce dementia incidence by understanding the mechanisms that drive the cognitive-physical aging trajectory.
