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.
The purpose of these studies are to evaluate the role of testosterone on autonomic and vascular function in men.
The reason for this study is to see if the study drug, selpercatinib, compared to placebo is effective and safe in delaying cancer return in participants with early-stage non-small cell lung cancer (NSCLC), who have already had surgery or radiation. Participants who are assigned to placebo and stop the study drug because their disease comes back or gets worse have the option to potentially crossover to selpercatinib. Participation could last up to three years.
Background: Data on the benefits of preoperative prophylactic antibiotics for breast surgery are conflicting and there is no guideline for their use for wire-localized lumpectomy. The aims of this study were to determine whether a single dose of pre-operative antibiotic reduces surgical site infection (SSI) for wire-localized lumpectomy and to identify risk factors for SSI. Methods: This was a prospective randomized trial carried out from April 2018 to June 2019 at the "Centre des Maladies du Sein du CHU de Québec - Université Laval", a tertiary center specialized in breast surgery. After informed consent, patients who underwent wire-localized lumpectomy were randomized to receive or not a pre-operative single dose of prophylactic antibiotic (cefazolin 2 g or clindamycin 900 mg in case of penicillin allergy). Data regarding demographics, comorbidities, perioperative details, and SSI were analyzed. SSI was considered if: 1) patient had positive wound cultures; or 2) required abscess drainage; or 3) received antibiotic treatment for breast symptoms (e.g., swelling, erythema, congestion) within 30 days after operation, in the absence of wound culture or in the presence of negative results. The patients and the investigator responsible for data collection were blind to grouping. All patients were called 30 days after surgery to be sure that they did not consult at another hospital for surgical wound infection.
The primary objective of this study is to test whether vaccinating adults ≥18 years in Hutterite colonies with mRNA-1273 (Moderna COVID-19) vaccine as compared to control (usual care) can prevent RT-PCR confirmed COVID-19 in non-vaccinated Hutterite members.
The purpose of this study is to evaluate the efficacy and safety of INCB054707 over a 24-week placebo-controlled double-blind treatment period, followed by a 28-week double-blind extension period in participants with nonsegmental vitiligo.
The proposed studies focus on memory for speech movements and sounds and its relation to learning. Continuous theta-burst transcranial magnetic stimulation (cTBS) will be used to suppress activity in a region of pre-frontal cortex associated with somatic and auditory working memory (Brodmann area 46v) to test its involvement in learning.
The purpose of this study is to compare the sensory return of DIEP flaps with nerve connection to DIEP flaps with no nerve connection to see which is better. This research is being done because the presence of sensation in a reconstructed breast has been shown to improve patient-related quality of life following mastectomy reconstruction and is an important safety factor for prevention of burns and other flap injuries. Unfortunately, women who have breast skin excised during mastectomy are reconstructed with a traditional DIEP flap that does not restore sensation to the skin.
Atopic dermatitis (eczema) is a complicated skin condition. In fact, it represents many different underlying problems. These include abnormalities in the skin barrier, the immune system and the ability to handle different bacteria. Despite many recent gains in the understanding of eczema, a lot needs to be learned. There is little evidence to select between some of the older treatments that are available now. Even the newest targeted therapy does not clear most patients' skin. In order to improve the understanding of eczema, how to treat it now, and to enable discovery of new treatments, the investigators plan to enroll patients into a large study at three centres in Canada (University of Toronto, McGill University and University of British Columbia). The study is called the Canadian Atopic Dermatitis Cohort for Translational Immunology and Imaging (CACTI). In this study, the investigators will collect data on how severe participants' eczema is and what treatments they use. For participants who give permission, the investigators will collect blood and skin biopsy samples to study the mechanisms underlying their disease. The investigators will test to see which form of phototherapy (Broadband or Narrowband Ultraviolet B phototherapy) works best for eczema in a randomized clinical trial. The investigators will also use advanced imaging techniques to visualize the skin. This trial registry entry, including the description of the treatment arms and outcomes, refer to the nested BROadband vs Narrowband photoTherapy for Eczema clinical trial.
COVID-19 has placed unprecedented strains on parents impacted by toxic stress (depression, addiction, intimate partner violence, and poverty) and reluctant to see mental health-service providers in home/clinic due to fears of infection. Due to the pandemic, Co-PI Letourneau ceased/delayed recruitment in VID-KIDS a CIHR-funded randomized controlled trials (RCT) of in-person (home or clinic) program designed to improve children's mental, emotional and behavioural (MEB) health and development via parent-child relationship intervention. Recognizing the heightened need for already vulnerable families to obtain safe parenting support to manage depressive symptoms/other stressors. Our primary knowledge user (D. McNeil, Scientific Director, Maternal Newborn Child and Youth Strategic Clinical Network, Alberta Health Services) advocated for online delivery of the VID-KIDS parent training program. In response, an interdisciplinary team from nursing and software engineering rapidly pivoted to an online delivery format. Critical barriers to using existing commercial technologies emerged, making it essential to develop and implement tailored, user-informed virtual care delivery platforms and tools safe, secure, user-friendly for families already stressed. This project aligns with the priority research area, Developing Innovative Adaptations of Services and/or Delivery, as innovative user interface design and integrated knowledge transfer approaches will be used to: (a) adapt VID-KIDS for virtual delivery; (b) develop virtual platforms (web-based applications) and tools (mobile apps) for flexible delivery of mental health supports for parents and training for professional facilitators; (c) integrate virtual mental health services into the primary care system promoting program uptake; and (d) design/test streamlined and intuitive virtual systems for nimble spread/scaleup. The project catalyzes and enriches the PIs' research program by crossing disciplines (nursing & engineering) in cutting edge research that is responsive to trends in both mental health intervention and web-interface design. This will be foundational for future tri-council RCT grants, expanding our research into user-engaged technology-enabled delivery of needed community interventions, especially relevant to promoting the urgent mental health needs of Canadian families in the COVID-19 context of physical distancing.
These studies test the hypothesis that the repeated pairing of somatosensory inputs with speech sounds, such as occurs during speech motor learning, results in changes to the perceptual classification of speech sounds.
