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 Exploratory study of the Edwards Transcatheter Atrial Shunt System is a multi-center, prospective, exploratory study to evaluate initial clinical safety, device functionality, and effectiveness of the Edwards Transcatheter Atrial Shunt System.
Move 2 Learn (M2L) is a 10-week movement and pre-literacy program for preschool aged children and their parents designed to improve both movement and reading skills as well as support their overall cognitive, physical, and psychological development. This study will be using a randomized wait-list controlled trial design to evaluate the program on several outcomes: motor skills, pre-literacy skills, cognitive function, perceived physical competence, and physical activity. Children ages 3 to 4 years with typical development will be randomized to either start the program immediately or enter the wait-list control group to begin the program after a 10-week control period. The outcomes will be assessed for all children three times, at week 0, week 11, and week 21 to evaluate change over time in both groups.
The purpose of this study is to determine if vitamin D as an adjuvant therapy can improve the outcome (i.e. fewer relapses) and the quality of life, including levels of physical activity, in children diagnosed Crohn's disease (CD).
Objectives The primary objective of this study is to determine the convergent validity of the mobile DSST application with the pencil and paper version of the DSST. Design and Outcomes This study will be performed by the Brain and Cognition Discovery Foundation (BCDF). The BCDF is an organization based in Toronto, Ontario, Canada led by Dr. Roger S. McIntyre. Membership of the BCDF has developed and validated rating scales and metrics for adults with mood disorders for over 10 years. A member of the BCDF provides diagnoses and treatment for adults (age 18-65) with mood disorders and provides clinical care to the largest catchment area in Canada. The BCDF conducts clinical research according to the International Conference on Harmonization, Declaration of Helsinki, and Good Clinical Practice (GCP) guidelines. The study will be approved by the community Research Ethics Board. Thirty adults (18-65) with DSM-5 MDD will be enrolled at the BCDF Toronto, Ontario. All subjects will have their diagnosis ascertained clinically and confirmed by Mini International Neuropsychiatric Interview Version 5.0 (M.I.N.I.). At baseline, data will be collected from all participants and will include demographics, comorbidities, medication history and concurrent medications. All subjects will be assessed symptomatically with the Montgomery and Asberg Depression Rating Scale (MADRS) as well as the Hamilton Anxiety Rating Scale (HAM-A), Snaith Hamilton Pleasure Scale (SHAPS) for anhedonia, as well as the paper and pencil version of the DSST at baseline and end of study (Day 7). The DSST has been normed on the sex, age and gender. These norms will be used as reference. All subjects will complete the pencil and paper version of the DSST and complete the mobile app-based version of the DSST. Sample Size and Population This is a small validation study of 30 subjects. Subjects diagnosed with major depressive disorder will be eligible for participation in this study.
The transition from pediatric to adult care is particularly difficult for individuals with Type 1 diabetes. It is hypothesized that a mindfulness-based intervention for individuals making this transition will contribute to personal psychological well-being, superior participation in health care, and more tightly controlled blood sugar levels. Young adults with Type I diabetes will complete an eight-week training program in Mindful Self-Compassion. Intervention effectiveness will be assessed with both self-report and physiological measures. Assessments will occur at the start of the training program, end of the program, and three-months post-program.
Researchers are testing a more accurate way to measure how much fluid is in the lungs (also called pulmonary edema, or "increased lung water") in people with Heart Failure (HF) using MRI (Magnetic Resonance Imaging). There is little known about the exact level of lung water in patients with AHF or how these levels change from the time of hospital admission to discharge. The purpose of this research study is to measure the lung water in patients hospitalized for HF, to determine the change in lung water over the course of hospitalization and treatment, and to find out if lung water levels can predict if patients are higher or lower risk for returning to the hospital or dying from heart failure.
Thoracic endovascular repair (TEVAR) and transcatheter aortic valve implantation (TAVI) are standard of care procedures to treat thoracic aortic aneurysm or severe aortic stenosis, respectively. Both procedures have a high risk of stroke and silent infarction. Gas has been detected in the cerebral vasculature during these procedures and associated with DWI positive lesions on MRI. The hypothesis is that air emboli contribute to stroke and silent infarction. The investigators propose addressing air emboli by flushing the device with carbon dioxide prior to flushing with saline. This is a pilot study comparing standard saline flush alone to carbon dioxide flushing with saline flush.
A substantial proportion of public safety personnel (PSP) develop service-related posttraumatic stress disorder (PTSD). PTSD is associated with a range of negative outcomes and its exact underlying neurophysiological mechanism is still not well understood. Cognitive behavioral therapy (CBT) is commonly prescribed to treat PTSD, and recent studies suggest that it may be effective in preventing the condition. We have developed a 5-session class focused on teaching introductory CBT skills to prevent and manage psychological distress, and we are currently in the process of launching a clinical trial to demonstrate its effectiveness in preventing PTSD and related conditions in PSP. In the proposed adjunctive study to this trial, we will quantitate the brain connectivity signature that is specific to the PTSD-resilience, and examine whether the classes increase this resilience-related brain mechanism.
Osteoporosis is a bone disease that increases the risk of fractures. People aged 50-65 diagnosed with osteoporosis feel too young to have the disease. But this happens. They need to learn how to modify their lifestyle to minimize the chances of fractures. In this age group, a wrist fracture is usually the first sign of osteoporosis. Fracture risk increases if they are not taught to exercise, eat properly, and identifies fall risk factors early in their diagnosis. Some studies have looked at interventions for osteoporosis in women over the age of 65, but by this age they have likely already had a spine fracture. No studies have addressed the early-onset osteoporosis age group, intervening before spine fractures occur. I will develop an exercise, nutrition, and falls prevention education program to improve the strength, balance and knowledge of people aged 50-65 who had an osteoporotic wrist fracture. I will use this treatment approach and determine if it is more effective than the usual way of treating people with wrist fractures, determining if this is a better strategy for managing osteoporosis. I will have two groups of patients. First, those, over six weeks, receive twice weekly classes that include exercise and education. Here the focus is on bone health and fracture prevention. The control will receive usual physical therapy and the educational materials at the end of their study participation. The treatment will be randomly allocated to 74 men and women between the ages of 50-65 years of age who are 6-10 weeks post-fracture. The outcomes on both groups will be assessed and compared. I will focus on hand function, balance, fall hazard detection, and a bone health behaviour checklist. Using these outcomes, I can determine which treatment approach works best. Osteoporosis affects one in three women and one in five men, making this an important study to improve the lives for many Canadians. The risk of osteoporosis fractures increases with age, making early interventions critical.
The goal of this randomized treatment study is to formally compare quality of life in patients with at least one pN0 hemi-neck after resection of a squamous cell carcinoma of the oral cavity treated with a primary radiation therapy versus a secondary targeted radiation therapy approach, to provide a high level of evidence to guide the selection of treatment options.
