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.
Endothelial injury as a consequence of SARS-CoV-2 infection leads to a dysregulated host inflammatory response and activation of coagulation pathways. Macro- and micro-vascular thrombosis may contribute to morbidity, organ failure, and death. Therapeutic anticoagulation with heparin may improve clinical outcomes in patients with COVID-19 through anti-thrombotic, anti-inflammatory, and anti-viral activities of heparins. This pragmatic, Bayesian adaptive randomized controlled trial will determine whether therapeutic anticoagulation with heparin (subcutaneous low molecular weight heparin or intravenous unfractionated heparin) versus usual care reduces the need for intubation or death in hospitalized patients with COVID-19. The trial uses an adaptive design which was chosen to overcome limitations in available data to inform a priori estimation of event rates and possible effect sizes. The adaptive design also includes response-adaptive randomization based on baseline D-dimer level, probing for differential efficacy across subgroups defined based on initial D-dimer level. This Bayesian adaptive randomized trial will stop at a conclusion 1) when the posterior probability that the proportional odds ratio is greater than 1.0 reaches 99% (definition of benefit); 2) when the posterior probability that the proportional odds ratio is greater than 1.2 is less than 10% (definition of futility) or; 3) when the posterior probability that the proportional odds ratio is less than 1.0 is greater than 90% (definition of harm). The trial will enroll a maximum of 3,000 patients, although in many simulations the trial may require fewer patients. The trial is strategically aligned with the international REMAP-CAP/COVID platform trial to accelerate evidence generation.
The unprecedented confinement and social distancing rules imposed by the fight against COVID-19 has forced the majority of the population worldwide to stay home for periods of time ranging from weeks to months. Eating habits are undoubtedly perturbed during this period, with consequential impact on food security. Therefore, the primary aim of this NutriQuébec sub-study is to document the impacts of the COVID-19 pandemic on diet quality and food insecurity of adults in the province of Québec in Canada. NutriQuébec is a web-based prospective cohort study launched in June 2019 whose primary aim is to provide data for the evaluation of the Government Health Prevention Policy on the Québec population's eating habits over the years (NCT04140071). Participants of NutriQuébec are invited to complete on a web-based platform nine core questionnaires on a yearly basis. Questionnaires assess several dimensions related to lifestyle, including eating habits and physical activity habits, as well as a large number of personal characteristics and global health status. For the purpose of this sub-study, NutriQuebec will invite the 2465 active participants who completed the first-year questionnaires prior to the COVID-19 pandemic to fill out again those questionnaires during the peak period of the confinement period in April and May, 2020. This NutriQuébec sub-study will provide invaluable data on how the COVID-19 pandemic impacts diet quality and food insecurity of adults in the province of Québec.
The loss of both muscle mass and quality with increasing age is called 'sarcopenia' and is a risk factor for falls, fractures and increased mortality. Sarcopenia is diagnosed with Dual-energy X-ray absorptiometry (DXA) scanning (according to current criteria), but in Canada DXA scans are not approved to screen for this condition. One potential solution is Point of Care Ultrasound (PoCUS), since recent advances have made bedside ultrasound technology readily available as a rapid bedside screening tool.
This is an open-label cohort study of chronic pain patients referred to an interdisciplinary community outpatient clinic. The aim of this study is to determine whether video consultations are non-inferior to regular consultations in diagnosing and planning subsequent interventions. The null hypothesis is that there is no difference in the International Statistical Classification of Diseases 10th edition (ICD-10) codes established via telehealth and subsequent clinic visits. The patients will complete standard health questionnaires online and undergo a structured and detailed interview to clarify the diagnosis and establish appropriate treatment. A limited telehealth physical examination based on direct observation will be conducted. At the subsequent clinic visit, the accuracy of diagnosis and adherence to the plan of care will be evaluated. The primary and secondary endpoints will be gathered from the electronic charts and from the recruited participants by questionnaires completed online one week after the telemedicine consultation. The diagnosis and plan of care semi-structured match will be performed during the in-person follow-up visit.
The purpose of this study is to evaluate the acceptability and effectiveness of two tools that may help address the management of deep dyspareunia: 1) A phallus length reducer (PLR, brand name: Ohnut), consisting of 4 interconnected silicone rings worn externally over the penetrating object to reduce pain with deep penetration by allowing adjustable limitation of penetration depth, and 2) A vaginal insert for at home self-assessment of the extent and severity of deep dyspareunia.
This study aims at investigating handwashing behavior during COVID-19 pandemic. It was hypothesized that social-cognitive and emotional predictors as well as COVID-19 morbidity and mortality rates within the country would be associated with handwashing behavior in the general population of adults in 14 countries.
The trial will be done to determine the impact of a barrier enclosure, COVID (coronavirus disease -19) barrier box on endotracheal intubation attempts, and duration. This study will be a prospective, open-label, randomized controlled trial. A total of 100 patients scheduled for elective surgery will be randomly assigned in two groups (intervention group and control group). Participating attending anesthesiologists will intubate the intervention group patients with COVID barrier box and the control group patients without the box. The anesthesiologists and the intervention group patients will be surveyed about their perception after the surgery. The result of this study will help in decision making about using COVID barrier box to minimize the viral transmission from patients to healthcare workers during the pandemic.
This Phase II study will recruit 40 metastatic non-small cell lung cancer patients who failed treatment with a platinum-containing doublet treatment and an anti-PD1 or PD-L1 immune checkpoint antibody, administered simultaneously or sequentially. All recruited patients will receive AB-16B5 at a dose of 12 mg/kg once weekly combined with docetaxel at a dose of 75 mg/m2 once every 3 weeks.
This study seeks to determine the prevalence of knee and ankle tendinopathies in youth basketball players, as well as determine the efficacy of a Basketball specific Neuromuscular training warm-up in reducing injuries.
Swallowing impairment (dysphagia) is extremely common in older adults living with dementia due to age-related changes in swallowing and other disease-specific impairments. Dysphagia is commonly managed by modifying diet textures rather than engaging in rehabilitative swallowing therapy. This means that countless people with dementia are left to eat pureed foods and drink thickened liquids, which are unpalatable and lead to malnutrition. As the disease progresses, many are transferred to nursing homes. In Canada, speech-language pathologists, who manage dysphagia, are consultants within nursing homes; therefore, swallowing therapy is non-existent. However, exercise therapy is more commonly available. Rodent models have demonstrated that physical exercise strengthens tongue and vocal-fold musculature, which are critical components of swallowing. Therefore, it is possible that whole-body physical exercise, which increases rate of respiration, will help to strengthen swallowing-related musculature in older adults with dementia. In this study, older adults (65+) with early-stage dementia will complete a 12-week physical exercise program to determine improvement of swallowing function.
