Filter by:This will be a (2 visit) double-blind, randomized, crossover design clinical study to assess the potential benefits of ER-CAFF versus IR-CAFF by assessing its impact on side effect profiles, mood states, alertness, and cognitive abilities following ingestion after a suboptimal night of sleep. This study will enroll 30 healthy men and women who will be recruited by word of mouth, email contact, and direct contact from the greater Tampa Bay Area. To account for potential dropouts, we aim to enroll approximately 20% over the desired sample size (total of 36 participants). The anticipated study period will last approximately 2 weeks. After initial pre-screening, participants will report to the laboratory on two separate occasions after an overnight fast (10 hours minimum). Participants will be required to have a night of partial sleep deprivation the night before (<5 hours sleep), which will be confirmed by self reported sleep logs and objective multisensor (triaxial accelerometry and cardiac data) wearable devices to accurately measure sleep deficit data. Upon arrival, participants will undergo baseline (BL) testing and then ingest a bolus of one study product with 4-8 ounces of water: 400 mg zümXR extended-release caffeine (ER-CAFF), or 400 mg of immediate-release caffeine anhydrous (IR-CAFF) (2 group, crossover design). Thereafter, participants will undergo subsequent testing sessions at 45, 60, 90, 135, 240, 300, 360, and 420 minutes post-supplementation. After the 4-hour (240 min) measurements, a caffeine-free food bar will be provided. This same food bar will also be offered to participants following the final 7-hour (420 min) measurements. The precise measures and timepoints for the measures are further defined below. There will be a one-week minimum washout period between treatments in the crossover design.
Given its capacity to stimulate exercise-induced neuroplasticity at lower doses compared to aerobic exercise, resistance exercise has become the top-recommended rehabilitation approach for individuals with neurocognitive impairments. Despite a large body of evidence supporting its application in the context of cognition, little work has been done to investigate the role of resistance exercise in modifying the structure and function of the microbiota-gut-brain axis. Likewise, despite a general understanding of the benefits of short chain fatty acids such as acetate for the gut-brain axis, the impact of exogenous acetic acid has not been sufficiently examined in the context of the intestinal barrier. While self-reported mood disturbance responds favorably to vinegar ingestion, it is currently unknown if these effects are also associated with changes in intestinal permeability.
Biodiversity is essential for nature and human well-being. Land use has reduced biodiversity in cities that is associated with altered commensal microbiota and a rising burden of immunological disorders among urban children. The investigators will estimate how rewilding of kindergarten yards affects commensal microbiome, prevalence of allergies, asthma, atopic dermatitis and infections, cortisol levels, cognitive skills and plasma cytokine levels of children. Our specific aims are: To assess if rewilding diversifies health-associated skin, saliva and gut microbiota and reduces infectious diseases and atopic or allergic symptoms. Assess whether the rewilding has positive effects on cognitive skills. Assess whether the rewilding changes cortisol and plasma cytokine levels. The investigators will recruit altogether 320 (160 per treatment) study subjects aged between 1-5 to questionnaire study (Task 2), from which 120 study subjects will be analyzed more detailed using microbiological and blood samples (Task 1).
The aim of the present study is to investigate the effects of different meal interventions on cognition (i.e., learning and decision making) and brain activity in healthy participants.
A 6-month pilot randomized controlled trial designed to test the effect of the Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) Diet + usual medical care versus usual medical care on cognitive change and several other secondary outcomes through a randomized controlled trial in 60 mild stroke patients aged 35-70 years without dementia.
This observational study aims to evaluate multiple dimensions of health in patients with Obstructive Sleep Apnea Syndrome (OSAS), before and after three weeks of ventilotherapy. Specifically, the study aims to identify pre- vs post-treatment differences in the following domains: - cognitive performance - blood expression of biomarkers related to neurodegeneration - psychosocial wellbeing Thus, patients will complete the following evaluations before (T0) and after (T1) ventilotherapy: - neuropsychological standard assessment - blood sampling - psychosocial self-reported questionnaires
The proposed project aims to develop and validate a multi-dimensional digital active aging program integrated with resilience to promote the biopsychosocial functions of older adults aged 60, including Chinese older immigrants in Canada (Study 1) and English-speaking White Canadian older adults (Study 2). The proposed study takes a typical pretest-training-posttest design. Pretest and posttest: a battery of outcome measures on physical, psychological, and social functions will be administered to all participants. Data will also be used to identify sociodemographic risk predictors for outcome variables (i.e., biopsychosocial functions and resilience). Training: the participants will be randomly assigned to three arms to receive 4 weeks of 16 training/practice/control treatment sessions delivered via Zoom. In the "active aging with resilience (AR)" condition, participants will complete physical, cognitive, and social engagement training modules, starting with a 30-min resilience-building module. The traditional "active aging" (AA) training involves the same multi-domain active aging training without the initial resilience-building module. The "workshop training" (WT) control condition involves workshops following the same 4-week schedule on aging-related topics.
This study will investigate the biological mechanisms linking sleep disruption by vibration and noise, and the development of cardiometabolic disease. In a laboratory sleep study, the investigators will play railway vibration of different levels during the night. The investigators will also measure objective sleep quality and quantity, cognitive performance across multiple domains, self-reported sleep and wellbeing outcomes, and blood samples. Blood samples will be analyzed to identify metabolic changes and indicators of diabetes risk in different nights. Identifying biomarkers that are impacted by sleep fragmentation will establish the currently unclear pathways by which railway vibration exposure at night can lead to the development of diseases in the long term, especially metabolic disorders including diabetes.
This study will compare the impact of a novel high-speed, cued yoga program to a standard yoga program on retinal microvasculature, cognition and neuromuscular function in persons with Parkinson's disease.
Previous studies in young adults have shown that physical activity can generate positive emotions and improve attention, among other cognitive functions. This highlights the importance of evaluating how physical activity can affect cognition and affective dimensions. However, to date, the dose of physical activity that could be most effective for these variables has not been established. This project aims to study the impact of acute physical activity on brain health in a university setting. Thus, this study will contribute to expand the current scientific literature on the acute effect of physical activity, a topic of great importance both in the educational field and from a public health point of view.
