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.
High blood pressure (present in 1 of 5 Canadian adults) increases the risk of heart attack and stroke. Blood pressure lowering pills reduce this risk - but perhaps not optimally. A Spanish study suggests that using blood pressure pills at bedtime, instead of in the morning (when they are most commonly used), reduces death, heart attack, and stroke by more than 50%. If true, a switch to bedtime prescribing would have more impact on the health of those with high blood pressure than whether high blood pressure is treated at all. BedMed, a community-based Canadian primary care trial, is already running and looking both to validate the findings of this Spanish study and to determine whether there might be unrecognized harms of bedtime use (such as more falls and fractures as a result of lower overnight blood pressure). One very important population that is likely to be more sensitive to the effects of medications, and almost always excluded from randomized trials, are the frail elderly (such as those who are resident in nursing homes). In order to have the greatest information about the safety and effectiveness of bedtime blood pressure medications, the BedMed team is additionally conducting a similar trial to BedMed in nursing homes ("BedMed-Frail" - the subject of this trial registration) to determine whether the risks and benefits of bedtime prescribing differ in this highly understudied population. Basics of the trial: When patients are admitted to nursing homes, neither they nor their physicians are consulted about the timing of blood pressure medication. Unless explicitly stated to be otherwise, blood pressure pills are instead largely arbitrarily assigned for morning use by default. Given there is evidence that bedtime administration may be safer, the nursing homes participating in BedMed-Frail will have each hypertensive resident randomized to either continue with morning blood pressure medication use, as is their norm, or to have their facility's pharmacist gradually switch each residents blood pressure pills to bedtime. Over a period of roughly 3 years, health outcomes in these facilities will be tracked using routinely collected electronic health data to determine differences in things like hospitalization, death, or hip fractures - and at the end of the study the investigators hope to determine whether or not the recommendations for blood pressure medication timing in frail older adults should differ from those for the general population.
The proposed study is designed to provide patients previously enrolled in Phase 1 and 2 studies of DCR-PHXC and their siblings (<18 years old) long-term access to DCR-PHXC, and to evaluate the long-term safety and efficacy of DCR-PHXC in patients with PH.
The purpose of this study is to investigate the impact of expiratory muscle strength training (EMST) on the swallowing, breathing, oral intake, quality of life and cough function of people with oculopharyngeal muscular dystrophy (OPMD).
A multi-site, interventional, non-comparative, single-arm trial to evaluate the safety of the Keeogo™ Dermoskeleton in subjects with hemiparesis due to ischemic or hemorrhagic stroke.
Nearly 1% of the Canadian population dies every year. When people die, their bereaved family members (FMs) normally experience grief that diminishes over time and without serious psychological or medical impairment. However, some FMs experience a severe grief reaction (SGR) with intense symptoms and impairment lasting months or years; this is more common among FMs of those who die in the Intensive Care Unit (ICU). Many bereaved FMs would like to have bereavement support, and many ICU organizations identify bereavement support as a clinical and research priority, yet few ICUs provide routine support. In order to determine the feasibility and acceptability of a complex support intervention for bereaved FMs, the investigators will pilot a multi-component bereavement intervention through a mixed-methods study. Methods will include a series of semi-structured interviews, questionnaires and narrative therapy sessions. The target population for this study is both ICU clinical staff (e.g. physicians, registered nurses [RN], allied health professionals) and FMs of relatives who died in the ICU. The intervention is premised on a robust series of educational modules aimed at increasing ICU staff members' knowledge of and level of comfort with bereavement support ICU FMs. In a previous study, the investigators have established that SGRs can be predicted using screening tools early after the loss, and that ICU-based clinicians are eager to provide bereavement support. There are effective treatments for SGRs once they have been diagnosed after 6 months, but this can mean many months of suffering for the FM. In this project, the investigators plan to develop and test the feasibility of an early bereavement support program that follows bereaved FMs after a loss, provides information and support, and uses effective therapies aimed at preventing the development of a SGR.
Dupuytren's disease can cause physical impairments that lead to reduced functional performance in personal care, work-related and leisure activities. The prevalence of Dupuytren's disease increases with age. A meta-analysis completed in 2014 by Lanting and al. estimated the its prevalence in western countries at 12% among people aged 55 years and over and at 29% among individuals aged 75 and over. The fasciectomy is the most current surgical procedure to reduce the flexion contracture occurring in this disease. Studies confirm the relevance of post-operative rehabilitation after fasciectomy. This rehabilitation is usually conducted by hand therapists who are mostly occupational therapists. However, the required duration and frequency of interventions and exercises for the post-op rehabilitation are not clearly described in the literature. In fact, the guidelines that are currently available recommend a total duration between 16 and 75 hours, which is highly variable. Also, the need to include supervised exercises by the occupational therapist is not specified. The main goal of this study is to compare two post-fasciectomy rehabilitation protocols to determine the influence of protocols intensity on motor and functional outcomes in people with Dupuytren's disease. The hypothesis is that the protocol involving a higher intensity will lead to better motor and functional improvements. The secondary goal of this study is to explore the link between the total time that the person has done the recommended exercises (combination of supervised exercises and the home program) and motor/functional recovery. The hypothesis is that the relationship between the amount of time and the motor/functional improvements will not be linear, but will either be logarithmic toward a plateau of recovery. A randomized controlled trial will be realized. 40 participants will be randomly assigned to one of the two rehabilitation protocols. Each participant will be evaluated at four times (initial evaluation, final evaluation and 2 follow-up evaluations). Data on motor and functional recovery will be collected.
The overall objectives of the study are to evaluate long-term safety of CTP-543 and to assess long-term effects of CTP-543 on treating hair loss in adult patients with chronic, moderate to severe alopecia areata.
Severe pediatric acute respiratory distress syndrome (PARDS) is a life-threatening and frequent problem experienced by thousands of children each year. Little evidence supports current supportive practices during their critical illness. The overall objective of this study is to identify the best positional and/or ventilation practice that leads to improved patient outcomes in these critically ill children. We hypothesize that children with high moderate-severe PARDS treated with either prone positioning or high-frequency oscillatory ventilation (HFOV) will demonstrate more days off the ventilator when compared to children treated with supine positioning or conventional mechanical ventilation (CMV).
This study will evaluate the long-term safety and efficacy of Bimatoprost Sustained Release (SR) in patients with open-angle glaucoma or ocular hypertension who completed 1 of the 4 Phase 3 Bimatoprost SR studies (192024-091, -092, -093, or -095) and received Bimatoprost SR or who received commercial DURYSTA (Bimatoprost SR) in the open-label Phase 4 ARGOS study (MED-MA-EYE-0648) and completed (or exited early from) the study.
Peripheral arterial disease (PAD) affects more than 200 million people worldwide. This disease occurs with narrowing and occlusion of arteries supplying oxygenated blood to the organs and limbs. Symptomatic patients typically experience leg pain with physical activity. More advanced disease states are referred to as critical limb ischemia (CLI), where patients may have leg pain at rest or non-healing wounds. Primary treatment of PAD involves risk factor management; smoking cessation, management of blood pressure, blood cholesterol, diabetes, and exercise prescription. Patients with CLI typically require interventions to reestablish blood supply to their limbs. There is currently minimal understanding of the role for exercise rehabilitation after revascularization procedures in this vulnerable population. This is the first clinical to understand the role of exercise for these patients. We hypothesize that exercise rehabilitation after revascularization will improve quality of life and functional capacity in these patients.
