Filter by:The compression therapy is a main treatment for chronic venous disease and its different phases. It has proven its effectiveness and usefulness in preventive phase and curative phase. Gérontopôle AURA leads with his partner Sigvaris a large study about the compression in institutions and at patient's homes. Indeed, through 3 studies, the mains goals are to identify the facilities and difficulties about the use of the actual tools. The final aim is to propose a future compression device wich could be adapted and that responds to the needs of users and the realities of the field. First study: Construction of a representative morphological database of people who are 60 years old and older. Indeed, the actually sizing tables are not specifics so not adapted to the morphology of the wearer. This can have an impact on the effectiveness of the treatment and the comfort of the patient. Second study: Have a deep comprehension about the pathway of the compression stockings and bandage in public and private establishment specifically retirements homes for dependant elderly people and hospital. The objectives are to understand and identify the role of health professionals from prescription to implementation to the compressive tools and have their feeds backs. Moreover, the goal is to collect the uses and constraints related to compression systems and to identify the possible improvements, needs and hindrances in link with compressions products. Third study: Study of acceptability of a new adjustable compression solution for venous ulcers. The main goal is to understand the needs and expectations by the users and to know if a new adjustable compression system could be accepted by them. For that, it's important to have a feed back about the use of the compression by the caregivers, medical staff and patients and evaluate the comfort about the use of the compression at patient's home and in institutions. Getting their advices, opinions are necessary too.
The objective of this clinical trial is to compare the health conditions of the participating population before and after an intervention with Resveratrol enriched wine. The main questions it aims to answer are: 1. • The consumption of wine enriched with resveratrol could slow down or reverse the biological age ? 2. • The consumption of wine enriched with resveratrol could improve body composition fat mass / muscle mass ? The participants will be evaluated at the beginning and at the end of the clinical trial and will adopt only one change in their habits, that is, change the usual wine they consume with their meals for a wine enriched with resveratrol, in a moderate measure, 250 cc for men and 125 cc/day for women. The design of the study will be that each volunteer is their own control, pre and post intervention.
This project will develop and test the effects and mechanisms of a music improvisation training intervention on self-regulation of older adults with and without MCI. The investigator's overall hypothesis is that improvisation training will lead to improvements in self-regulation, compared to controls, and that improvisation training will be associated with specific changes in prefrontal brain networks and ultimately cognitive engagement.
Aging is commonly associated with reduced functionality of the immune system, resulting in a higher prevalence of infectious disease, auto-immune disease, cancer, and lower efficiency of vaccination. Nutritional strategies are increasingly recognized as a method to improve immune functionality, as several nutrients are shown to exert immunomodulatory properties. However, the large variation between individuals with regard to immune responses asks for more personalized approaches. Therefore, this field of research would benefit from a selection of those individuals with immune dysfunction. It is recently shown that immune functionality is largely dependent on intracellular metabolism, leading to the introduction of the new term 'immune cell fitness' which combines the metabolic and functional status of an immune cell. Within this study, we will determine the immune cell fitness of monocytes from healthy young adults and elderly subjects by measuring and integrating a broad range of metabolic and functional immune parameters into an immune cell fitness score. We aim to identify those individuals with immune dysfunction, the unfit. Furthermore, to identify potential nutritional strategies to improve immune cell fitness, we will study the effects of metabolites and nutrients on the immune cell fitness status of monocytes from elderly subjects.
The goal of this pilot study is to examine predefined parameters (sample size, capacity building, acceptance by community-dwelling older people (participants) and care providers) to evaluate the feasibility of implementing World Health Organization's ICOPE (integrated care for older people) approach in China. The main questions it aims to answer are: 1. Whether it is feasible to implement the ICOPE approach in China; 2. Whether the integrated care approach would make any difference in health outcomes and resource utilization. Participating older adults receiving integrated care (Intervention Group) are compared to those receiving usual care (Control Group) in order to answer the two questions above.
The goal of this clinical trial is to compare the effects of protein consumption before sleep or immediately after exercise during 12 weeks of resistance exercise training in older adults. The main questions it aims to answer are: Are there differences in muscle growth or strength during 12 weeks of resistance training when 40 grams of protein is consumed either before sleep or immediately after exercise? Are there differences in cognitive performance during 12 weeks of resistance training when 40 grams of protein is consumed either before sleep or immediately after exercise? This study is a randomized double-blind placebo-controlled study. Participants will be randomly allocated into 1 of 3 groups. All three groups will perform the same 12-week resistance exercise training program two times per week and consume 40 g of protein: 1) Immediately post-exercise, 2) 30 minutes prior to sleep, or 3) no supplemental protein (control). Test of muscle growth and strength, and cognitive performance will be measure before, during, and after the exercise training program. Researchers will compare the 3 conditions to determine if consume protein after exercise or before sleep during 12 weeks of resistance exercise training affects muscle growth and strength, and cognitive performance.
The purpose of this clinical trial is to investigate the feasibility and efficacy of non-invasive transcranial alternating current stimulation (tACS) at gamma frequency in enhancing memory recall and modulating sleep network dynamics measured by at-home electroencephalography (EEG) in healthy elderly people. Eligible participants will first collect sleep EEG at home for one night to acclimate to the data collection during sleep. Participants are then randomized into first undergoing either tACS at gamma band frequencies (i.e. 40Hz) or tACS at a control frequency (i.e. 21Hz). Stimulation is administered in the lab during a cognitive testing battery that includes memorizing items. After a night of sleep with EEG at home, participants return to the lab the following day to measure memory recall. Recall is performed again after five days. This sequence of encoding during stimulation in the lab, sleep EEG at home for one night, and recall is then repeated for the other stimulation condition about a week later. Participants are wearing an actigraphy wristband throughout the study period.
Cardiovascular disease (CVD) is the number one cause of death globally and high blood pressure (i.e., hypertension) is the leading modifiable risk factor for CVD and all-cause mortality. Advancing age is the primary risk factor for hypertension and CVD. Moreover, compared to younger adults, older adults exhibit reduced nocturnal dipping of blood pressure resulting in elevated nighttime blood pressure values, which are a better predictor of cardiovascular outcomes than daytime blood pressure. Intriguingly, recently published rodent data suggests that ketone supplementation protects against hypertension, blood vessel dysfunction, and kidney injury. Whether ketone supplementation provides vascular health benefits in humans remains to be determined. Therefore, the investigations seek to conduct an acute ketone supplementation study to determine whether ketone supplementation may restore a more healthy nighttime blood pressure phenotype in middle-aged and older adults. The investigations will also determine whether ketone supplementation influences nocturnal heart rate variability, a non-invasive of autonomic function that may be influenced by ketone supplementation in a manner that influences blood pressure.
The primary goal of this intervention is to determine the efficacy of acute mitochondrial-specific antioxidants to improve vascular endothelial function in middle-aged and older (≥45 y) adults who do no perform regular aerobic exercise. In a double-blind, randomized, placebo-controlled crossover design participants with receive both MitoQ and placebo arm of the study. Primary endpoints will include vascular endothelial function assessed by brachial artery flow-mediated dilation and cardiac function assessed via pulse wave analysis. Secondary endpoints will include measures of aortic stiffness assessed by carotid-femoral pulse wave velocity and carotid artery stiffness (e.g. β-stiffness) and elasticity (carotid compliance, distensibility, and Youngs elastic modulus) from ultrasonography.
An acute randomized crossover trial comparing the effects of the whey hydrolysate, whey protein concentrate and placebo (still flavored water) on appetite and energy intake in older adults. Both low-dose whey-derived treatment and placebo will be administered 30 minutes prior to breakfast and lunch meals. Moreover, ghrelin secretion and activity will be monitored throughout the morning until the lunch time. Appetite will be assessed through visual analogue scale questionnaires.
