Filter by:The LIGHT PAD Trial is a Phase II multi-centered randomized clinical trial to collect preliminary data to test whether daily far red light treatment of the lower extremities in people with PAD improves six-minute walk distance, lower extremity perfusion, and ischemia-related damage in gastrocnemius muscle at four-month follow-up, compared to a sham control. Participants will complete 10 minutes of twice daily home treatment with either far red light or a sham light for four months.
The study investigates the impact of consuming hydrogen-rich water over a six-week period on exercise-related biomarkers among individuals aged over 50, both men and women, who undergo a resistance training program. This research aims to discern the potential benefits of hydrogen-infused water consumption concerning exercise-related markers in an aging demographic post-resistance training.
Purpose: This study aimed to determine the effect of 48 weeks of resistance training (RT) on cardiac function in older women. Methods: Sixty-four older women (≥ 60 years), physically independent, were selected for this study. Participants were randomized into a training group (TG, n = 33) and a control group (CG, n = 31). The RT program was conducted over 48 weeks, three sessions a week, on nonconsecutive days, in the morning hours. Participants performed eight exercises for the whole body (chest press, horizontal leg press, seated row, leg extension, triceps pushdown, lying leg curl, preacher curl, seated calf raise) in three sets of 8-12 repetitions. The echocardiography was performed according to current guidelines before and after 48 weeks by an experienced echocardiographer blinded to patient status and group assignment. One-repetition maximum (1-RM) tests were used to analyze muscular strength. Glusoce, lipid profile, and C-reactive protein were measured. DEXA was used to measure body fat and muscle mass.
With the increasing regularity and intensity of hot weather and heat waves, there is an urgent need to develop heat-alleviation strategies able to provide targeted protection for heat-vulnerable older adults. While air-conditioning provides the most effective protection from extreme heat, it is inaccessible for many individuals. Air-conditioning is also energy intensive, which can strain the electrical grid and, depending on the source of electricity generation, contribute to green house gas emissions. For these reasons, recent guidance has recommended the use of electric fans as a sustainable cooling alternative. While fans may increase sweat evaporation and heat loss in healthy, young adults, evidence supporting their use in older adults is scarce. Further, studies show that when environmental temperature exceeds skin temperature, fans are not effective and can even exacerbate hyperthermia in older adults. While older adults only account for ~13% of the population, they account for ~40% off all hospitalizations. In the context of sustainable cooling interventions, this is of particular importance given that many hospitals and long-term care homes do not have air-conditioning and rely on ceiling fans to enhance sweat evaporation while participants are bed-resting. While recent biophysical modelling has suggested that pedestal fans likely provide a clinically meaningful cooling effect (proposed to be ≥0.3°C) in temperatures below ~34°C in older adults, the efficacy of ceiling fans in mitigating heat strain in these conditions is currently unknown. To address these knowledge gaps, this randomized crossover trial will evaluate body core temperature, cardiovascular strain, orthostatic intolerance, dehydration, and thermal comfort in adults aged 65-85 years exposed for 8-hours to conditions experienced during indoor overheating occurring during a heat wave in a temperate continental climate (31°C, 45% relative humidity). Each participant will complete two randomized exposures that will differ only in the airflow generated by a ceiling fan: no airflow (control) or standard airflow. Participants will remain in a supine position for the duration of the 8-hour exposure period, except for during hour 7 when they will complete a series of cardiovascular autonomic response tests.
While scientific evidence emphasizes the detrimental effect of sedentary behavior on health, the literature suggests that, on average, older adults spend 75% of their days in a sedentary manner, and often isolated (Petrusevski 2020). This lack of physical activity and social interaction not only leads to an increase in functional limitations and the risk of worsening an existing chronic disease but also elevates the risk of mortality. Furthermore, older adults face progressive functional decline, both in motor and cognitive aspects, as a result of aging, contributing to inactivity and sedentary behavior (Botö 2021). The literature suggests that new technologies such as immersive virtual reality (iVR) and serious games serve as effective means to promote active leisure, thereby breaking isolation and reducing sedentary behavior. The development of these new technologies is also promising for objectively and quantitatively measuring motor and cognitive activity (e.g., kinematics, reaction time). Serious games are defined as games whose primary objective is more focused on learning than entertainment. For instance, they allow the integration of physical and cognitive activity programs into a playful activity, conducive to long-term adherence. Their effectiveness is starting to be studied in hospitalized older adults (Cuevas-Lara 2021), especially as they also help combat age-related functional decline. Indeed, they provide the opportunity to promote and measure activity through enjoyable and self-administered exercises. However, despite the growing interest in serious games, the impact of self-adaptive serious games, compared to traditional (non-adaptive) serious games, on motor skill learning and attention function in older adults remains unclear. This gap in knowledge necessitates a rigorous investigation. Therefore, this randomized controlled trial seeks to address this gap and achieve the following objectives: 1. Compare the effect of a self-adaptive serious game to a non-adaptive serious game on motor skill learning and attention in older adults. 2. Enhance the understanding of how motor skill learning in immersive virtual reality translates to older adults' activities of daily living.
This is a pilot clinical trial to test the efficacy of intermittent treatment with the flavonoid compound fisetin for improving vascular endothelial function and reducing aortic stiffness in older adults. This trial will also determine the potential mechanisms by which fisetin may improve vascular function, including by decreasing mitochondrial oxidative stress, cellular senescence and senescence-associated secretory phenotype (SASP) factors in circulation. Lastly, safety, tolerability and adherence of fisetin treatment will be assessed.
The goal of this clinical study is to learn about the effect of aging on certain enzymes, or proteins, in the blood and colon. The study involves collection of blood and colon tissue biopsies using a flexible sigmoidoscope or colonoscope. This study is also investigating how medications tenofovir and emtricitabine interact with certain enzymes. The investigators will compare the difference in enzyme activity between people taking tenofovir and emtricitabine, to those who are not taking tenofovir and emtricitabine.
In a recent report, the World Organization for Health provided some evidence that artistic and cultural activities can support the health and well-being of the population. Our previous research suggests that the effect of museum visits on well-being and stress might be tied to relaxing proprieties of contact with art objects, especially when the artwork is viewed with an introspective and self-reflexive approach. This study addresses the effect of a well-being museum intervention of six weeks on cerebral activity associated with artwork contemplation during a museum visit and assesses how it affects the psychological and cardiovascular health of older adults with and without atrial fibrillation. The well-being intervention will engage the participant in a series of 6 visits, in groups of 10, oriented on his feelings, impressions, and interpretations of artworks. This well-being museum intervention will be compared to visits typically provided in the museum, in a cross-over single-blinded design.
This study focuses on the role of neutrophils in shaping the adaptive immune response to the anti-pneumococcal vaccine Prevnar-13 in young and elderly adults.
The Interventions for Brain Health Virtual Reality Study is a NIH-funded clinical research trial at the University of California San Diego (UCSD) Health under the supervision of the study principal investigator Dr. Judy Pa. The overarching goal of this trial is to use a novel virtual reality (VR) based intervention that simultaneously engages physical and cognitive activity aimed at improving brain health and cognition in older adults. The investigators will compare 3 types of interventions: physical activity, VR cognitive activity, and combined VR physical and cognitive activity over 16 weeks to evaluate physical and brain health changes.
