There are about 28871 clinical studies being (or have been) conducted in Canada. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The purpose of this study is to assess if wearing a surgical mask affects the results of a standard treadmill test.
Study to assess the effects of weekly subcutaneous administration of the GLP1-RA semaglutide 2.4mg on kidney function parameters in obese/overweight individuals at high risk of CKD progression.
Teenagers with eating disorders often experience a disruption in care upon turning 18. At this age, they are no longer eligible to receive pediatric treatment but are also not yet set up with the appropriate adult services. There are currently no supports in place to help youth with eating disorders and their families during this transition from child to adult care. In this project, the investigators will be implementing an intervention designed to improve this transition experience; it will include peer support, parent education, a meeting with the child and adult care providers, contact with the family doctor, and a written guide about the transition. Among 10 adolescent-parent pairs leaving McMaster Children's Hospital to adult programs in Hamilton, Ontario, the investigators will assess how feasible the intervention is to implement, how feasible the chosen measures are, participants' experience of the intervention, how many adolescents actually transition to adult care, as well as a few adolescent and parent outcomes, such as how prepared the teen feels or what the parents' needs are.
Acute exercise increases the incorporation of dietary amino acids into de novo myofibrillar proteins after a single meal in controlled laboratory studies in males. It is unclear if this extends to free-living settings or is influenced by training or sex. Over 24 h in a free-living setting, the investigators determined the effect of training status and sex on dietary phenylalanine incorporation into contractile myofibrillar and noncontractile sarcoplasmic proteins after exercise.
Previous studies have used a combination of oral L-[1-13C]leucine and intravenous labeled L-[5,5,5-2H3]leucine to assess the acute postprandial changes in whole-body protein turnover (12, 19). Intravenous and dietary-labeled amino acid tracers have also been used in tandem to assess rates of myofibrillar protein synthesis in response to bolus protein ingestion and resistance exercise (46). By validating whole-body net balance to myofibrillar protein synthesis, our proposed multi-tracer approach will develop minimally invasive models to study protein turnover in a variety of populations in which traditional infusions and/or repeated blood samples are not possible (i.e. pediatric, free-living populations).
This study will examine two separate interventions: 1) the effects of ischemic preconditioning or 2) a high fat meal on the capacity of the brachial artery to overcome sympathetic activation and dilate during exercise (also known as functional sympatholysis). Participants will be asked to complete rhythmic handgrip exercise with and without the application of -20 mmHg lower body negative pressure to increase sympathetic activation. Doppler ultrasound will be used to continuously measure brachial artery blood flow. Participants will complete the handgrip exercise and lower body negative pressure before and after the applications of each interventions. Participants may elect to only complete one intervention rather than complete both protocols. Intervention one is active or control ischemic preconditioning. Intervention two is high or low fat meals.
This study was a multi-site, prospective, randomized, non-masked, unilateral, non-dispensing study.
This study will be a randomized, double-blind, placebo-controlled trial of a third dose of Moderna vaccine versus placebo. Participants will be those that have received two doses of mRNA-1273 COVID vaccine (Moderna) at 0 and 1 months. Participants will be randomized 1:1 to receive either a third dose of the mRNA-1273 vaccine or saline placebo at 3 months post initial vaccination.
Over 700,000 Canadians are affected by dementia costing the health care system approximately $10 billion/year. Due to COVID-19, the government has urged individuals over the age of 70 to stay home, putting this population at risk of social isolation. Older adults with mild cognitive impairments (MCIs), dementia, and their caregivers are at an even higher risk of becoming stressed, anxious, and agitated while in lockdown. Unsurprisingly, caregiver burden is extremely common, and often precedes institutionalization of the patient, as the demands of the illness begin to exceed that which the caregiver can sustainably provide. Since social distancing measures have shut down activities and support groups for these individuals, there is an urgent need for scalable, cost-effective, non-pharmacological interventions that can be delivered remotely to improve stress and loneliness. Yoga may be a viable therapeutic modality to address the psychological challenges associated with dementia in patients and caregivers, as it has been shown to decrease stress and improve anxiety and depressive symptoms in various populations. For this reason, the investigators are conducting a randomized controlled trial (RCT) to assess the efficacy of an 8-week virtual chair yoga program to improve stress, psychological symptoms, and caregiver burden. This virtual chair yoga study will engage both older adults with dementia/MCI and caregivers (n=40-60 participants) during COVID-19, which is consistent with the need for decreasing costs and increasing accessibility of novel health interventions during and beyond the pandemic. The investigators will evaluate the effect of this program on stress, loneliness, and mental health related outcomes such as fear of COVID-19, depression, anxiety, and caregiver burden compared to a waitlist control group. There will also be a qualitative component in the form of semi-structured interviews. All quantitative outcomes will be assessed before the program starts and post-intervention and qualitative outcomes will be assessed post-intervention. Participants will be randomly assigned to the treatment group (virtual chair yoga 1 hour per week on Zoom) or the waitlist control group. The investigators hypothesize that after the 8-week yoga program, older adults and caregivers will report lower stress, loneliness, depression, anxiety, fear of COVID-19, and caregiver burden. Results will be available late-2021.
The purpose of this study is to determine the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), maximum tolerated dose (MTD) (if reached) and early signs of efficacy of M4076 monotherapy in participants with solid tumors in dose escalation (Part 1A). Once the recommended dose for expansion (RDE) is declared in Part 1A, a preliminary food effect cohort, Part 1B, will follow at the RDE determined from Part 1A.
