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.
Open-heart surgery requires temporarily stopping the heart and lungs and diverting the patient's blood to an outside system that takes over the function of the heart and lungs. This is possible through the use of cardiopulmonary bypass (CPB) which diverts blood, through plastic tubing, to a heart-lung machine which includes an oxygenator. The external oxygenator works as an artificial lung. This allows cardiac surgeons to operate in a field that is free of blood, while the patient's body continues to receive healthy blood. CPB is an advanced medical technology that allows for heart surgeries, such as coronary artery bypass, heart valve surgery, and procedures involving major blood vessels. It is recognized that there are many risks associated with its use, including microscopic stress exerted on blood components by the oxygenator and tubing, which can lead to irreversible damage to the blood cells. This effect can contribute to bleeding during and after surgery. This type of bleeding can be difficult to monitor and treat, especially given the limited access to point-of-care blood testing to inform clinicians on what part of the blood is failing to function properly. The investigators will use a point-of-care machine called Plateletworks to test the function of platelets during surgeries which require CPB. Platelets are an important part of blood that help stop bleeding by forming clots. At the investigators' institution two oxygenators are currently used interchangeably. These oxygenators have different properties that may impact how platelets function. This project will help determine if using a higher pressure oxygenator increases the risk of patients bleeding. Additionally, the investigators will compare the platelet data from Plateletworks to data collected from rotational thromboelastometry (ROTEM). This will yield valuable data about commonly used oxygenators and tests which can ultimately improve patient care.
This RCT will test the effect of a 7-week self-help ACT-based program in improving fertility-related quality of life and psychological flexibility, in women with infertility.
Phase I to evaluate the safety and feasibility of same-day discharge in selected participants undergoing minimally-invasive lung surgery and who receive an enhanced recovery pathway.
The purpose of this study is to establish how personalization of repetitive transcranial magnetic stimulation (rTMS) can change markers of brain activity and improve treatment response. To do this, all participants will receive the same active form of treatments, but some of the participants in this study will receive intermittent theta burst stimulation (iTBS) rTMS treatment with standard forms of targeting and intensity, and others will receive iTBS rTMS treatment using personalized magnetic resonance imaging (MRI) and electric field (E-field) modeling measures.
A 52-Week Study of Ritlecitinib Oral Capsules in Adults and Adolescents with Nonsegmental Vitiligo (Active and Stable) Tranquillo
The purpose of this study is to measure improvements in liver fibrosis and inflammation with GSK4532990 compared with placebo in participants with NASH and advanced fibrosis on biopsy (F3 or F4). The study duration will be up to 76 weeks including the screening period. The treatment duration will be up to 52 weeks.
A randomized, double-blind, placebo-controlled multicenter, phase 3 study to evaluate the efficacy and safety of tezepelumab administered subcutaneously (SC) using an accessorized pre-filled syringe (APFS) versus placebo in adult and adolescent patients with eosinophilic esophagitis (EoE).
TOPCOP3 is a pilot factorial RCT of geriatric assessment and management, remote symptom monitoring, both interventions or neither, accompanied by an embedded process evaluation. This design is widely used to guide the evaluation of complex interventions and provides important data to aid design of larger RCTs. The trial itself falls within pilot trial goals including obtaining variance estimates for outcomes, assessment of recruitment potential, and understanding implementation issues vital to designing a larger trial. The investigators have clear feasibility objectives and an analytic plan as well as criteria to determine success and strong support from cancer advocacy and policy groups.
Research suggests that strength-based parenting programs can enhance family well-being, but the current formats of these programs (e.g., in-person workshops) are not accessible to many families. The first aim of the study is to adapt Strengths to Grow, an accessible and engaging strength-based parenting program, for pre-teens. The second aim of the study is to assess the effectiveness this adapted program (Strengths to Grow: Preteen). Toward this end, parents of children in Grades 4 through 8 will be invited to complete a brief, online survey of well-being before and a few weeks after completing the online program to assess its impact on well-being.
The heart is a pump that must both fill and empty effectively to move blood; if it cannot move enough, heart failure may ensue. Approximately half of all adults living with heart failure have a form where the heart stiffens, which impairs its ability to fill. This form of heart failure particularly affects females and older adults. When people exercise, extra blood returns to the heart. The healthy heart can easily fill and move this extra blood to the muscles. However, when the heart's ability to fill is impaired, the extra blood can back up and pool in the lungs. Blood pooling in the lungs makes people feel breathless, although the investigators do not fully understand why, and this form of heart failure has a high risk of hospitalization and death, but few effective treatments are available. Exercise is one of the few treatments that works well if enough exercise is performed regularly. However, many people with this form of heart failure can only tolerate a small amount before stopping due to severe breathlessness, which can put them off from exercising regularly. The study's goal is to help these people perform more exercise. The investigators will use a novel form of stationary cycling with a plastic chamber around the lower body that seals at the waist. The chamber can apply suction to the lower body during exercise which will reduce how much extra blood returns and prevent the heart and lungs from being overloaded. Participants will attend 5 visits, including 3 where they will perform a submaximal exercise test for as many minutes as possible with or without light suction. In each of these tests, the investigators will record how long they exercise and ask them to rate how breathless they feel. The investigators will also study their breathing pattern, using a mouthpiece and pressure sensor, and heart function, using ultrasound imaging. This work will help adults living with heart failure exercise more and improve their health, and help researchers understand what causes breathlessness and develop new treatments.
