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 study will evaluate the safety and effectiveness of the Globe® Pulsed Field System for treating patients with symptomatic paroxysmal or persistent atrial fibrillation (AF).
Chronic diseases are the leading health problem in Brazil and Canada. Such diseases share common risk factors in common, such as physical inactivity, poor diet, and smoking. This context requires a comprehensive approach to change these behavioural risk factors, aiming at the promotion of healthy lifestyles and the prevention of diseases. Although Brazil and Canada have significant differences, particularly in terms of socioeconomic factors, some similarities in the health domain allow both countries to mutually benefit from an exchange of knowledge. For instance, the newest version of Canada's dietary guidelines has incorporated several aspects presented in the pioneering evidence-based dietary guidelines for the Brazilian population, launched in 2014. Similarly, Brazil can greatly benefit if the country follows the Canadian lead in prioritizing investment in physical activity initiatives. The present project aims to verify the effectiveness of a Canadian program to change health behaviours, specifically physical inactivity, poor diet, and smoking, adapted for Brazilians. The project consists of a 12-week randomized controlled trial, based on education and behaviour change techniques focusing on physical activity, healthy eating habits, and smoking cessation. Pre-, post, and 3-month follow-up health and fitness assessments will evaluate respectively the initial condition of the participants, eventual changes and if the changes persist.
According to the CDC, approximately 47% of the population suffers from moderate or severe periodontitis. A byproduct of periodontal disease is loss of the alveolar bone surrounding the natural tooth root as well as around the dental implant in cases of peri-implantitis, and if allowed to proceed far enough, can cause mobility and eventual loss of the tooth or implant. Traditional and time-tested methods of treating periodontitis involve a meticulous mechanical cleaning of the root surfaces to remove the causing factors, both above and below the gumline. This reduction or elimination of the etiologic factors that trigger the pathologic and damaging immune response is very effective at reducing the inflammation. High Frequency Vibration (VPro+), when used as an adjunctive therapy following traditional treatment for periodontitis where the chronic inflammation has been lowered, controlled or eliminated has the potential to enhance the mechanical properties of the bone by increasing bone density by way of a low-risk, non-invasive, self-applied therapy that is patient-friendly and affordable. Improvement in bone density can translate clinically to lowering of tooth mobility, and lessening the chance of orthodontic relapse after orthodontic therapy. It is further hypothesized that, if conducted in an environment of low or nonexistent periodontal inflammation, VPro+ therapy may also contribute to enhanced the degree of bone fill after healing of angular periodontal bone defects and low-grade furcation involvements, and as thus may turn out to be a less invasive and more affordable option to periodontal bone grafting surgery, the current standard of care for those particular situations. The goal is to conduct a randomized clinical trial using patients in our graduate periodontology program to test the efficacy of high frequency vibration in improvement of tooth mobility and other periodontal indices in test group versus control group.
To evaluate the feasibility of a 6-month multidisciplinary program to reverse prediabetes in adults with coronary heart disease using the Mediterranean diet, intermittent fasting and exercise.
Pediatric obstructive sleep apnea is a medical condition where a child has great difficulty with breathing, or stops breathing all together, while asleep. This is a medical condition for which the primary treatment is usually a surgery targeted towards removing swollen tonsils and adenoids. However, surgical removal of tonsils and adenoids comes with its own risks of complications during and after surgery including secondary hemorrhage and long term increased risks for respiratory and infectious diseases. Perhaps more importantly, surgical removal of swollen tonsils and adenoids does not guarantee successful treatment of a child's obstructive sleep apnea. The use of laser light therapy in a non-cutting manner (known as photobiomodulation and abbreviated as PBM) has been a relatively new development within medicine. Recently, dentists have begun to use PBM as a method to treat adult snoring and, with lesser success, adult obstructive sleep apnea. To date, there are no known side effects to the use of PBM for the treatment of any sleep breathing disorders. However, no research has been published on the use of PBM for the treatment of pediatric obstructive sleep apnea or swollen tonsils in children The purpose of this project is to determine whether photobiomodulation can provide a beneficial effect on pediatric hypertrophic tonsils and pediatric obstructive sleep apnea and, if it does, to create the appropriate workflow, referral pathways, and treatment parameters for clinicians to provide this treatment as a multidisciplinary approach in a clinical setting. The investigators hypothesize that photobiomodulation can be used successfully to decrease the pediatric hypertrophic tonsils in children with symptoms of an pediatric obstructive sleep apnea and will also result in improved AHI scores (be able to breath significantly better when sleeping) in these children.
The coronavirus pandemic has severely affected healthcare systems and changed life as everyone know it, globally. Apart from the acute phase disease complications, it is now apparent that a significant proportion (15%) of patients who recover continue experiencing symptoms such as chronic fatigue, shortness of breath, joint pains, cognitive impairment ("brain fog"), etc. for several months, if not for life. This syndrome has been labeled as "long-COVID" or Post-Acute COVID-19 Syndrome (PACS) and can happen to anyone whether you're young, old, healthy, or have a chronic illness. One can get it even if the COVID-19 symptoms were mild. There is no confirmed cause as to why this happens. However, there is data to support that inappropriate activation of the immune system by the virus may play a role. While our immune system is programmed to protect us against foreign invaders (such as viruses), in this case, it is directed against elements of our own. The net result is autoimmunity, where the immune system produces autoantibodies that cause damage to the body. This may lead to the development of chronic and serious diseases like lupus, rheumatoid arthritis, vasculitis, scleroderma, and others.The aim of our study is to understand the exact impairment of the immune system, why these patients develop autoantibodies, characterize their impact on the clinical symptoms of PACS, and, potentially, identify ways to modify this. The study's impact is significant since it is projected that 150000 Canadians will experience (or are already experiencing) this syndrome.
For people living with kidney failure, the two active treatment options are dialysis or kidney transplantation. Transplantation is optimal, and especially from a living donor - offering patients longer survival, a better quality of life, and cost savings for the health system when compared to dialysis. However, 20% of patients die on dialysis while waiting for a deceased donor organ. As the rate of kidney failure continues to rise, the gap between demand and supply of the organs for transplantation increases. Compared to other provinces in Canada, the rate of living kidney donor transplantation is lower in Alberta, so it is essential that improvements are made to the process around living kidney donor transplantation, for better patient outcomes and care. Our published evidence-based review on strategies to increase living kidney donation, found that for patients with kidney failure, the intervention with the greatest health impact was personalized support, provided by a multidisciplinary team, to inform and educate the patients' social network. A province-wide survey also confirmed that many patients with kidney failure are unable to find a living kidney donor and also find it difficult to approach potential donors due to lack of skills, supports, and resources. The investigators have developed the Multidisciplinary Support To Access living donor Kidney Transplant (MuST AKT) intervention to support potential kidney transplant recipients find living donors through their social networks, and thereby increase the number of living kidney donor transplants in Alberta. The investigators will test the effectiveness of this intervention.
Data on valve performance following ViV-TAVR has usually been obtained with the use of Doppler-echocardiography. However, some reports have shown significant discordances in the evaluation of mean transvalvular gradient between echocardiography and catheterization, with an overestimation of the real gradient with echo (vs. cath) in most cases. Thus, the incidence of procedural-device failure may be lower than that reported in the ViV-TAVR literature,
This is a multicentre prospective cohort trial in adult and pediatric ICU patients. The investigators will measure the effect of a patient's inspiratory effort during mechanical ventilation on the lungs and diaphragm. The investigators will daily (for a maximum of 8 days) measure esophageal pressures with a balloon catheter to quantify inspiratory effort and respiratory muscle function, and perform daily ultrasound measurements of the diaphragm and the lungs. The investigators hypothesize that a small inspiratory effort will result in the preservation of diaphragm function and have no adverse effect on lung function.
The purpose of this study is to assess the safety and tolerability of zilovertamab vedotin as monotherapy and in combination in participants with select B-cell lymphomas including mantle cell lymphoma (MCL), Richter's transformation lymphoma (RTL), follicular lymphoma (FL), and chronic lymphocytic leukemia (CLL). This study will also evaluate zilovertamab vedotin as monotherapy and in combination with respect to objective response rate. - Cohort A: Participants with relapsed or refractory MCL relapsed or refractory disease after at least 2 prior systemic therapies including a Bruton's tyrosine kinase inhibition/inhibitor (BTKi), and post therapy chimeric antigen receptor T (CAR-T) cell therapy or ineligible for CAR-T cell therapy - Cohort B: Participants with relapsed or refractory RT disease after at least 1 prior systemic therapy - Cohort C: Participants with relapsed or refractory MCL relapsed or refractory disease after at least 1 prior systemic therapy and no prior exposure to a non-covalent BTKi - Cohort D: Participants with relapsed or refractory FL and CLL relapsed or refractory disease after at least 2 prior systemic therapies and have no other available therapy - Cohort E: Participants with relapsed or refractory FL after at least 2 prior systemic therapies and have no other available therapy - Cohort F: Participants with relapsed or refractory CLL after at least 2 prior systemic therapies and have no other available therapy The primary study hypothesis is that zilovertamab vedotin monotherapy has an increased Objective Response Rate (ORR) per Lugano Response Criteria as assessed by blinded independent central review (BICR).
