Filter by:This study aims to produce new evidence on the efficacy of exercise and diet for cardiometabolic risk reduction in BC survivors. Using a 3-arm RCT with to 6 months of 1) exercise following Health Canada guidelines; 2) the same exercise plus counselling to follow Canada's Dietary Guidelines to improve diet quality; or 3) stretching group, this study will answer the following questions: - What is the impact of exercise on cardiometabolic health and body composition in BC survivors? - What is the effect modification of adding a diet quality intervention to exercise on cardiometabolic health and body composition? - Is there a link between the capacity of skeletal muscle adaptation to exercise (and diet) and insulin resistance in BC survivors? The investigators hypothesize that: 1) exercise will improve cardiometabolic and body composition outcomes 2) improvements in cardiometabolic outcomes will be enhanced by the addition of diet quality, which will be essential or additive for Matsuda index, metabolic syndrome, Framingham CVD risk, thigh myosteatosis, muscle mass, VO2peak, 3) skeletal muscle insulin signalling transduction will be impaired in BC survivors via dampened expression of insulin-responsive proteins (e.g. GLUT4) and co-occur with impaired muscle quality (e.g., higher rates of fat depots, presence of fibrous tissue) negatively impacting insulin signalling.
This study will determine if ingestion of 3 g/d betaine versus placebo for two weeks prior to a 60-km cycling time trial will improve performance, moderate exercise-induced gut permeability, and improve metabolic recovery.
This study aims to produce new evidence, specific to women, on the efficacy and mechanisms of exercise and diet for cardiometabolic risk reduction in pre and postmenopausal women. Using a 3-arm randomized controlled trial (RCT) with equal recruitment and stratification by menopausal status to 6 months of: 1) exercise following Health Canada guidelines; 2) the same exercise plus counselling to follow Canada's Dietary Guidelines to improve diet quality; or 3) stretching group, this study will answer the following questions: - How does the impact of exercise compare among each of the causal links between physical inactivity and cardiometabolic disease in women? - What is the effect modification of adding a diet quality intervention to exercise? - What is the effect modification by menopausal status? The investigators hypothesize that exercise adaptations will be: 1) largest peripherally, including Matsuda index (primary outcome), Homeostatic Model Assessment of Insulin Resistance (HOMA-IR), arteriovenous oxygen difference (avO2diff), and visceral fat, compared to centrally (stroke volume (SV), endothelial function, aortic stiffness), 2) blunted or absent in post vs premenopause; 3) enhanced by the addition of diet quality which will be essential or additive for Matsuda index, metabolic syndrome, Framingham cardiovascular disease (CVD) risk, cytokines and adipokines, thigh myosteatosis, muscle mass, peak oxygen uptake (VO2peak), 4) enhanced by adding diet quality in more outcomes postmenopause.
Glycaemic responses to fruit smoothies may depend on the food matrix (e.g., degree of processing and physical structure), ingestion rate, dose ingested and fibre content. Furthermore, the method of sampling could alter inferences. The aim of this project is to characterise how these factors affect the glycaemic response to a commercially available fruit smoothie. Participants will ingest 7 different test drinks in a randomised, crossover design with fingerstick capillary blood sampling alongside continuous glucose monitors. Test drinks will include a glucose reference (CONTROL), the commercial product matched for carbohydrate to CONTROL (PRODUCT), equivalent carbohydrate ingested as whole fruits (WHOLE), equivalent carbohydrate ingested as blended fruits (WHOLE), equivalent carbohydrate as the commercial product ingested slowly (SLOW), equivalent carbohydrate as the commercial product ingested with additional fibre (FIBRE), and the commercial product ingested in a dose typically bought (DOSE). These data will provide insight into how the food matrix and different patterns of ingestion can alter the glycaemic response to a fruit smoothie, and how the measurement method may alter interpretations.
The goal of this clinical trial is to explore the potential of metformin in managing olanzapine-induced metabolic disturbance and hyperprolactinemia in patients with schizophrenia. The main questions it aims to answer are: 1. The effect of metformin on olanzapine-induced metabolic disturbance 2. The effect of metformin on olanzapine-induced hyperprolactinemia Participants will receive metformin 1500 mg/day for 8 weeks and assessments every 2 weeks.
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 is a pilot study in 10 men to test the hypothesis that perturbations in substrate flux and the circulating metabolic and pro-inflammatory milieus during a high-fat diet paradigm will modulate DNA methylation of genes in sperm associated with obesity and cardiometabolic dysfunction.
Two bioactive compounds, N-trans-caffeoyl tyramine (NCT) and N-trans-feruloyl tyramine (NFT), have been investigated for potential gut health benefits. The shells of hemp seeds are a rich source of NCT and NFT. The hypothesis for this project is that ingestion of a hemp fiber bar containing NCT and NFT will mitigate exercise-induced increases in gut permeability. This study will examine the efficacy of 2-weeks ingestion of a hemp fiber bar (high and low doses) in moderating exercise-induced gut permeability using a randomized crossover trial. Objective #1: To conduct a randomized crossover trial using placebo-controlled, double-blind procedures with 20 cyclists who will in random order ingest a hemp fiber bar supplement (high and low doses) or placebo each day for two weeks prior to an exercise challenge (2.25 hours of intensive cycling). Objective #2: To determine if hemp fiber bar supplementation attenuates exercise-induced gut permeability using several outcome measures including plasma lactulose to 13C mannitol (L:M) ratio and plasma intestinal fatty acid binding protein (I-FABP) as markers of gastrointestinal permeability and mucosal damage, respectively. Shifts in thousands of metabolites will be measured via untargeted metabolomics to provide additional gut permeability biomarkers and help reveal underlying mechanisms.
This study aims to establish the metabolic/molecular response in both adipose tissue and skeletal muscle as well as sensory experiences (pain, fatigue, drive) to prolonged fasting of 3 days duration. Participants will undergo sequential meal assessment before and after a 3 day fast with measures taken throughout each fasting day.
A cross-sectional study will be conducted, which will include 80 young patients with psoriasis, aged 30-45 years, treated with five different types of antipsoriatic treatment, and 20 healthy patients. All 100 subjects will be subjected to anthropometric measurements, blood will be collected for laboratory tests, and an imaging test will be performed to determine the function of the endothelium and arterial stiffness. The results will then be statistically analyzed.
