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.
Angiotensin converting enzyme-2 (ACE2) is part of the renin-angiotensin system (RAS), which is involved in maintaining blood flow and electrolyte balance. It has been shown in obese and hypertensive individuals that levels of another molecule Angiotensin converting enzyme (ACE) are much higher, leading to inflammation, fibrosis, vasoconstriction and high blood pressure. ACE2 has a protective effect from ACE, leading to anti-inflammatory, anti-fibrotic and vasodilating effects. In animal models, it has been shown that aerobic exercise can increase levels of ACE2, while decreasing levels of ACE and offers protection to the cardiovascular system by keeping these two molecules balanced. Although the effects of exercise on the classical arm of the RAS have been studied significantly, ACE2 is a relatively new discovery and has not been studied as extensively in humans. The purpose of this research is to determine the effects of exercise training status on the RAS, specifically on ACE2 and its products.
The Prodigy system, developed by Cerebra Medical Ltd, allows for the generation of the same information in the home that is currently only obtained in in-laboratory studies. The objective of the current study is to demonstrate that the signals obtained by this comprehensive, portable system are comparable to those obtained in in-laboratory studies.
This study will explore the effectiveness of two different interventions, a Health Action Process Approach (HAPA) mobile health (mHealth) intervention and a Just In-Time Adaptive Intervention (JITAI), on reducing sedentary behaviour in office workers. One third of participants will receive the mHealth HAPA intervention, consisting of a theory-driven behavioural counselling session with personalized daily SMS text messages, and another third of participants will receive the JITAI intervention, a behaviour tracking mobile phone application that will alert participants once a set sedentary behaviour condition has been met. The last third of participants will act as a control where they will not receive an intervention or any further information from the letter of information. The study will take place over four weeks, with the first acting as a baseline and the intervention period filling the latter three weeks.
The purpose of this study is to compare the positive and negative effects of Dex4® tablets, as an alternative form of fast acting carbohydrate, compared to the current standard diagnostic test, glucose beverage. The investigators hypothesis that because of their availability in solid, chewable form, variety of flavours and lack of carbonation, Dex4® tablets may result in fewer side effects than glucose beverage and provide an equivalent carbohydrate challenge for diagnosis of gestational diabetes.
Risdiplam works by helping the body produce more survival motor neuron (SMN) protein throughout the body. This means fewer motor neurons - nerve cells that pass impulses from nerves to muscles to cause movement - are lost, which may improve how well muscles work in people with SMA. RO7204239 is an investigational anti-myostatin antibody that is designed to target myostatin. Myostatin plays an important role in the regulation of skeletal muscle size by controlling growth. Inhibiting myostatin may help muscles grow in size and strength. RO7204239 in combination with risdiplam, which is designed to increase the amount of SMN protein throughout the body, has the potential to further improve motor function and clinical outcomes for people living with SMA. This trial will study the safety and efficacy of RO7204239 in combination with risdiplam in patients with spinal muscular atrophy (SMA). The trial has two parts; Part 1 is the dose-finding part in SMA patients that are either ambulant (aged 2-10 years) or non-ambulant (aged 5-10 years) within separate cohorts, and Part 2 is the pivotal part in SMA patients aged 2-25 years that are ambulant.
People that have difficulty with balance have a higher risk of falling and reduced quality of life. Some individuals can learn to compensate using their vision, their sense of where their limbs are in space, and balance organs that are still intact. Rehabilitation exercises, which typically involve shaking and nodding of the head, are often prescribed for dizzy patients but are not effective for everyone. Our study aims to determine if specific exercises performed on footplate sensors with visual feedback is superior to traditional rehabilitation exercises done at home for improving balance and quality of life.
Cognitive complications, that is problems with thinking and memory, are incredibly common after surgery, occurring in 10-50% of all older surgical patients. These complications can take different forms, but one of the most common is postoperative delirium (POD), a short-term state of confusion. In addition to being stressful for patients and their families, POD is linked to longer hospital stays, increased costs, higher mortality rates and other problems after surgery. Despite this, POD is often not recognized by doctors and there are currently no effective medications to treat POD. However, simple strategies such as helping patients to sleep properly and remain hydrated, have been shown to help. This study is testing if a delirium-reduction program will reduce postoperative delirium (POD) in older surgical patients. The investigators will first test memory and thought processes before surgery to find people who are most likely to develop POD. Once these people have been identified, they will be enrolled in a program which includes recommendations for their care team (e.g. surgeon, anesthesiologist, nurses) as well as educational materials for them and their family related to things that can be done to prevent delirium. By identifying at-risk patients and making sure that their doctors and caregivers are aware of how to prevent delirium, the investigators expect that this study will make surgery safer for older surgical patients.
With the aging population, the prevalence of dementia is increasing dramatically. People living with dementia are highly dependent on family care partners, who may have little knowledge of the disorder. National and provincial guidelines have all highlighted the importance of online resources to improve care partner education; however, very few have been widely implemented or rigorously studied. The investigators have developed the award-winning dementia education platform to complement traditional patient and family educational approaches. It allows free access to multimedia e-learning lessons, live expert webinars, and email-based content that care partners can access any time, anywhere. In a pilot randomized controlled trial (RCT), the investigators propose to study 1) the feasibility and care partner acceptance of the intervention and some of the study methods, and 2) the impact of the intervention on care partner self-efficacy, knowledge, and sense of burden. This initiative has the potential to improve the quality, cost effectiveness, and efficiency of dementia care. The intervention could be easily scaled and spread both provincially and nationally to complement other dementia education methods, at a time when the prevalence of dementia is increasing and access to high quality internet-based interventions is essential.
Pneumonia in children can be caused by different types of germs such as bacteria and viruses. Giving antibiotics to children with bacterial bugs is helpful while giving antibiotics to children with viruses will not help them. Unfortunately, it is difficult for doctors to tell when a child's pneumonia is caused by bacteria or viruses. Most young children are given antibiotics even though it doesn't help them. Our study wants to test a new way to care for children with pneumonia so that only children who will benefit from antibiotics will receive them. The study will use a combination of the child's symptoms, x-rays results, and lab testing to better determine if a child needs antibiotics. The study team will then review the testing results and follow up with the patient and their family in the following days to ensure that the child is improving. PIONEER will test a novel care pathway for treating non-severe pediatric pneumonia with the goal of decreasing antibiotic prescription while maintaining equal clinical outcomes to standard care.
Antenatal corticosteroids (ACS) reduce the risks of neonatal death and morbidities in preterm infants, such as respiratory distress syndrome. The standard of care for pregnant people at risk of preterm birth includes 2 doses of Celestone (for a total of 24 mg in Canada, or 22.8 mg in Australia) to accelerate fetal lung maturity. The investigators plan to conduct a randomized controlled trial to determine whether half the usual dose (12 mg in Canada, or 11.4 mg in Australia) of Celestone is non-inferior to the standard double doses.
