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.
This pilot study will test the effect of a 6-week self-help program in improving fertility-related quality of life as well as anxious and depressive symptoms, in women with infertility.
There have been concerning case reports of marked elevations of LDL-c in some individuals consuming a KD and Dr. Lewis has been referred a number of these cases to his lipid clinic, some of whom have had extreme elevations of LDL that mimic familial hypercholesterolemia. These marked elevations of LDLc are unique to a ketogenic diet and far exceed the typical mild elevations seen in those consuming a high fat, low carbohydrate LGIT. The degree of elevation of LDL-c suggests that ketosis per se may impair LDL receptor-mediated LDL particle clearance. This clinical observation is a concerning and clinically important issue since millions of people are consuming this popular diet. There are currently no studies that have examined the mechanism of the LDL-raising effect of a ketogenic diet.
This is a prospective, observational cohort registry that aims to collect data on pulmonary structure and function in healthy people and those with respiratory disease, using structural and functional pulmonary 1H-MRI and hyperpolarized 129Xe-MRI. Outcome measures generated from MRI may include but are not limited to measures of regional ventilation, pulmonary microarchitecture, and regional gas exchange. Additionally, one of the goals of the registry is to facilitate the development of novel image analysis techniques that have not yet been invented. These data will be stored along with demographic data, clinical data, and pulmonary function testing (PFT) data. This is an open registry. Eligible local and international investigators/institutions can apply for access.
PREVENT is a multicentre, 2x2 factorial, randomized clinical trial that aims to determine the effect of cytisine versus placebo, as well as the effect of video messaging to support smoking cessation versus standard of care in perioperative patients. This trial aims to investigate the effects of cytisine and text messaging on 6-month continuous abstinence rates. PREVENT will also assess secondary outcomes at 30 days, 56 days and 6 months post-randomization: 7-day point prevalence abstinence, urge to smoke, time to first lapse, time to relapse, number of cigarettes smoking if still smoking, pulmonary complications, vascular complications, wound and infectious complications, stroke, time in hospital and acute hospital care.
To demonstrate the safety and effectiveness of the Reducer system for treatment of patients with refractory angina pectoris treated with maximally tolerated guideline-directed medical therapy who demonstrate objective evidence of reversible myocardial ischemia in the distribution of the left coronary artery and who are deemed unsuitable for revascularization. A non-randomized single-arm will further assess the safety and effectiveness of the Neovasc Reducer System in selected subjects with reversible myocardial ischemia in the distribution of the right coronary artery and who are deemed unsuitable for revascularization, subjects with reversible myocardial ischemia without documented obstructive coronary disease and subjects who cannot complete an exercise tolerance test due to an above-the-ankle amputation.
This study will investigate the efficacy and safety of OZURDEX® (dexamethasone intravitreal implants; DEX, Allergan, Inc. Irvine, CA) as monotherapy for the treatment of non-infectious intermediate-, posterior- or panuveitis. This is a prospective randomized controlled clinical trial taking place at the University of Ottawa Eye Institute, Ottawa, Ontario, Canada, and other possible centers in Canada. Consecutive consenting subjects who meet inclusion/exclusion criteria will be selected to participate in this study. The subjects must have either non-infectious intermediate, posterior, or panuveitis. The subjects will be randomly chosen to be part of one of two groups; one group will receive DEX as monotherapy and the other group will receive oral prednisone. Approximately 84 eyes (42 per arm) will take part in study. The primary outcome will measure the proportion of eyes with a vitreous haze score of 0 six months post initial treatment. Secondary measures will include best corrected visual acuity (BCVA), central retinal thickness (CRT) measured by spectral-domain optical coherence tomography (SD-OCT), time to vitreous haze resolution and time to failure defined at number of months with DEX implant until an adjunct therapy is indicated. Baseline measurements will be recorded within 1 month prior to treatment in both groups, with follow up measurements collected at 0, 1, 2, 4, 6 and 12 months post-operatively.
The purpose of this study is to compare treatment with olorofim versus treatment with AmBisome® followed by standard of care (SOC) in patients with IFD caused by proven IA or probable lower respiratory tract disease Aspergillus species (invasive aspergillosis, IA).
Total hip or knee replacement is an important and cost-effective surgical intervention to relieve pain and improve independence and function in patients with osteoarthritis. The number of people waiting for elective surgeries has spiked in the COVID-19 pandemic. Prior to COVID-19, up to 40% of patients receiving joint replacement were frail and this number is rapidly increasing with longer wait-times and deconditioning associated with COVID-19 physical distancing. There is an urgent need to be responsive to the evolving challenges of healthcare. The proposed study is the first multi-site randomized controlled trial (RCT) to examine whether a multimodal frailty reduction intervention before surgery will improve postsurgical outcomes for this population. The COVID-19 adapted hybrid model includes a multimodal frailty intervention that may be implemented either in person or virtually and is aligned with international consensus guidelines on frailty reduction. To utilize the FitJoints multimodal frailty intervention to build resilience of patients undergoing joint replacement surgery to improve post-operative outcomes. The investigators hypothesize the FitJoints multimodal frailty intervention, with exercise, nutrition and medication optimization, will reduce frailty and pain while improving function and quality of life. Building upon the success of the FitJoints feasibility study (n=69) in Hamilton, Ontario, in the proposed multi-site RCT (n=192), older adults (≥60 years) undergoing hip or knee joint replacement surgery who are frail will be randomized to either the 3 to 6-months of multimodal intervention or usual care until the date of their surgery at multiple sites (Hamilton Health Sciences & St Joseph's Healthcare Hamilton, ON; London Health Science Centre, London, ON; Foothills Hospital, Calgary, AB),The FitJoints evidence-based, multimodal intervention includes a hybrid model that can be implemented either in person or virtually: 1. Physiotherapist supported multi-component exercise program 2. Nutrition and protein optimization including dietary counseling 3. Medication review with prescribing recommendations
This study will investigate if the SSERT (Social Skills and Emotion Regulation Training) intervention is feasible and acceptable in individual with psychotic disorder and a history of trauma.
Total knee arthroplasty (TKA) is a frequent performed surgery. Many institutions are implementing outpatient programs for this surgery and adequate pain management is an important feature. Analgesic duration of single shot nerve blocks is limited to no more than 24h. Conversely, the use of continuous nerve block (CNB) through a perineural catheter and infusion of local anesthetic may increase duration of analgesia and provide better outcomes. The purpose of this study is to evaluate effectiveness and safety of using CNB in patients undergoing ambulatory TKA, and its effects on patients' quality of recovery. We hypothesize that continuous adductor canal block would lead to a better quality of recovery in patients undergoing outpatient TKA.
