Filter by:The use of non-medical cannabidiol (CBD) has been growing recently in France and in the world, in young but also older adults. Few data are available on the use of cannabidiol in older adults. A better knowledge of the use of cannabidiol in older adults, and of their own knowledges of the molecule, is necessary to guide and follow the CBD uptake in this population and avoid potential adverse events.
Playful interactions have an important role in human sociality. During playful interactions, two individuals continuously co-create an imaginary world together, such as playing roles in an imaginary scene or co-creating synchronized movements together. Playful interactions are characterized by an enhanced sense of flow and joy and have been associated with physical and psychological well-being across the lifespan. This research team and others have shown that playful interactions are particularly beneficial for the older population, which are at higher risk of cognitive decline and social isolation. The overarching aim of this proposal is to conduct an in-depth investigation of the effects of playful interactions, in older population. Specifically the investigators will test the effect of short playful interaction on cognitive measures, as well as social and affective indices, and compare them to a non-playful interaction (such exercise class, or personal conversation).
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.
The retrospective cohort study will compare the prevalence of sarcopenia and associated factors between older patients who have undergone bariatric surgery and older patients with obesity without previous bariatric surgery.
Appearance of superficial radial cheek lines and fine lines of the cheek are signs of photoaging. These lines appear in a curvilinear or crosshatched fashion on the lower cheeks in photoaged individuals. They represent a common concern among patients seeking cosmetic treatments. With the aging population and increasing social awareness of cosmetic treatments, it is likely that the demand for filler procedures will increase. Current treatment options for these lines include fractionated and fully ablative laser resurfacing, topical retinoids, intradermal filler injections, and chemical peels. One potential treatment for facial fine lines include use of low G' hyaluronic acid fillers, which allow for dynamic movement while also addressing the appearance of the lines. Resilient Hyaluronic Acid (RHA) Redensity is an FDA-cleared filler used for treatment of dynamic perioral rhytids. Hyaluronic acid-based fillers have been shown to improve overall skin texture (skin surface hydration, roughness, and elasticity) through the hypothesized mechanism of inducing a fibroblast response to boost collagen production. They have the potential to reduce appearance of facial fine lines of the cheek. This study will evaluate the efficacy of RHA Redensity in improving radial cheek lines.
The glycocalyx serves as the interface between flowing blood and endothelial cells, the single cell layer that lines blood vessels, and is crucial for normal blood vessel function. Specifically, the glycocalyx protects endothelial cells from oxidative stress and inflammation and enables blood vessel dilation, which is largely dependent on the bioavailability of the vasodilatory molecule nitric oxide. Importantly, glycocalyx thickness decreases with age and is predictive of major adverse cardiovascular events in older adults free of cardiovascular disease. Therefore, interventions aimed at restoring glycocalyx thickness in older adults are desperately needed. Endocalyx Pro is a commercially available glycocalyx precursor supplement, manufactured by Microvascular Health Solutions, designed to 1) repair a damaged glycocalyx, 2) protect against damage to the glycocalyx, and 3) synthesize new glycocalyx components, and has been used to increase glycocalyx thickness in humans. However, no study has tested if glycocalyx thickness restores glycocalyx thickness in older adults and improves blood vessel function. Thus, the purpose of this investigation is to determine if 12-weeks of Endocalyx Pro supplementation alters glycocalyx thickness and blood vessel function in older adults. The investigators will use a camera placed under the tongue to determine glycocalyx thickness. The investigators will measure blood vessel function by measuring brachial artery dilation with ultrasound and arterial stiffness using pressure probes placed on the carotid and femoral artery.
Exercise is routinely recommended because of its benefits for physical, cognitive, and mental health. It is especially beneficial for older adults due to its potential buffering effects against Alzheimer's disease and related dementias (Luck et al., 2014). However, little is known about how to best encourage older adults to exercise. Based on behavior change theory, different intrapersonal and interpersonal motivational factors are likely to be relevant during the contemplation, action, and maintenance stages of behavior change. Generally, as a result of motivational shifts toward prioritizing positivity and socially meaningful goals with advancing age (Carstensen, 2006), socioemotional aspects of decision making may become more salient and influential for older adults (Mikels et al., 2015; Peter et al., 2011). Our previous work has demonstrated that positive affect (Mikels et al., 2020) and social goals (Steltenpohl et al., 2019) play a critical role in older adults' motivation to exercise, but these two lines of research have not been integrated to date. Recent work indicates that positive affect is particularly beneficial for health when shared in social connections (Fredrickson, 2016; Major et al., 2018), and the proposed work will, for the first time, examine how shared interpersonal positivity may impact exercise decision making and behavior, especially during the contemplation and action/maintenance stages of behavior change. But who are the older adults that benefit the most from exercise in terms of physical, cognitive, and mental health (and should be hence be targeted with messages)? Not all older adults reap the benefits of exercise (Sparks, 2014) and, conversely, sedentary older adults have the most to gain. Overall, the current proposed research program is innovative in its (a) translational application of insights from affective, cognitive, and aging theory and research to understand the antecedents and outcomes of exercise decision making in younger and older adults, (b) conceptualization of both the social and emotional aspects of decision making, (c) development of novel methods for health messaging that incorporate social influences, and (d) novel assessments of the exercise-health link.
The goal of this randomised, double-blinded, placebo-controlled trial is to investigate the immune, metabolic and cognitive effects of four weeks of daily ketone supplementation in adults aged 60 to 80 with stable health. The main objectives are to assess the effects of the intervention versus placebo on markers of metabolic health, inflammation, immune function, adipose tissue, and cognitive performance. Participants will undergo two weeks of baseline monitoring followed by a four-week supplementation period in which they will drink a ketone monoester drink or taste-matched placebo three times a day. During these periods, participants will record their diet and supplement intake and their physical activity and blood glucose will be monitored using wearable devices. At the beginning and end of the supplementation period, participants will undergo testing in the university physiology laboratories, involving blood, expired air and adipose tissue samples, as well as cognitive tests, physical tests and questionnaires.
The aim of this project will be to compare the acute effects of breaks from sedentary behavior using dual-tasking on cerebral blood flow, vascular function, cognitive functions and blood pressure in elderly people. Participants will perform, in random order, three experimental sessions (control, break with dual-task and standard break ([walk]). All sessions will have a period of 4 hours in sedentary behavior. In the standard break session and in the break session with dual-task participants will take walking and dual-task breaks every 30 minutes, and in the control session they will remain seated without breaks. Before and after this period, cerebral blood flow, vascular function, cognitive functions and blood pressure will be assessed.
This is a prospective, interventional, double-blinded placebo-controlled study of up to 40 participants to evaluate the effect of a botanical formulation on inflammatory biomarkers and epigenetic age.
