Filter by: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
This is a randomized, double-blind, placebo-controlled, 4-week intervention clinical study assessing the efficacy of Mirtoselect®, Virtiva® Plus, and Enovita® on cognitive performance and mood states, and the occurrence of adverse events in response to daily supplementation. The desired sample size for this study is 64 subjects. To account for potential dropouts, we aim to enroll up to 20% over the desired sample size. Therefore, this study will enroll up to 76 healthy men and women (25-55 years of age). Subjects will be randomly divided into four study groups: Placebo, Virtiva® ginkgo biloba extract, Mirtoselect® bilberry extract, or Enovita® grape seed extract. Blocked randomization will be deployed in which subjects are divided into blocks of 4 subjects and each subject within a block is randomly assigned to one of the four study groups.
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.
The goal of this interventional clinical trial is to test the effectiveness of improving cognitive development in newly born infants fed with Feihe investigational formula product containing HMO, and DHA/ARA. The main question it aims to answer is: - whether the score of Bayley-III cognitive scale (tested at the age of 12 months) of participants in the study product arm is significantly better than participants assigned in the other two arms. 240 qualified participants will be randomized to 3 arms (investigational formula, control formula, and breast-feeding) to consume assigned formula or breast-feeding for 12 months according to protocol. There will be up to 6 site visits arranged for each participant during the study, and all relevant clinical and questionnaire data, including the most important Barley-III cognitive scale data at the age of 12 months, will be captured, recorded and entered to CMTS (Clinical Management Trial System) for statistical analysis and reporting. Researchers will compare the three arms to validate the assumption that the consumption of Feihe investigational formula product containing HMO, and DHA/ARA will improve cognitive development in newly born infants, along with physical development.
