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.
Randomized controlled trial comparing coblation debridement to mechanical debridement in rotator cuff repair.
Patients with heart disease are often prescribed many medications and these patients may experience drug interactions or negative drug related side effects. With newer medications and treatments available, it is not well known whether older drugs, such as beta-blockers, are still an effective and safe option for treating heart disease. Some evidence suggests beta-blockers should be continued, whereas other evidence suggests beta-blockers might cause unnecessary harm. The study hopes to determine whether continuation or discontinuation of beta-blockers will affect long term cardiovascular outcomes. The study investigators will also examine how beta-blockers continuation or discontinuation affects several quality of life measures.
Atopic dermatitis (AD; also known as atopic eczema) is an inflammatory skin disease. The safety and effectiveness of upadacitinib for AD has been well-documented in previous studies, however, important information is missing on the use patterns and outcomes with upadacitinib in a real-world setting. Therefore, the purpose of this observational study is to help inform real-world usage patterns regarding the safety and effectiveness and duration of response of upadacitinib in adolescent and adult AD participants >=12 years old in the real-world setting. Upadacitinib is an approved drug being developed for the treatment of AD. Around 975 adolescent and adult participants who are prescribed upadacitinib for the treatment of AD in routine clinical practice will be enrolled worldwide. Participants will receive oral upadacitinib as prescribed by their physician. Data from these participants will be collected for approximately 2 years. There will be no additional burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the course of the study at a hospital or clinic and will be asked to provide additional information by questionnaire at each visit.
ML-004-002 is a multi-center, randomized, double-blind, parallel-group, placebo-controlled study that will enroll approximately 150 adolescent and adult subjects with ASD. The primary objective is to evaluate the efficacy of ML-004 compared with placebo in the improvement of social communication deficits in subjects with ASD.
This study consists of 2 parts: Dose Escalation Part 1 and Dose Expansion Part 2. The Dose Escalation Part 1 will evaluate the safety and tolerability of Avelumab in combination with Lenvatinib and determine the recommended Avelumab and Lenvatinib dose for expansion. Dose Expansion Part 2 will assess the efficacy of Avelumab in combination with Lenvatinib by Progression-free Survival in participants with pre-defined primary central nervous system (CNS) tumors.
The Placebo-Controlled Efficacy in Idiopathic Normal Pressure Hydrocephalus (iNPH) Shunting (PENS) trial is a multi-center blinded, randomized, placebo-controlled design investigation of cerebrospinal fluid (CSF) shunt surgery to study the shunt efficacy in iNPH patients.
People with vascular conditions are at risk of having memory problems, and these memory problems increase the risk for further cognitive decline. Brain stimulation has been used to improve mood and memory. Transcranial direct current stimulation (tDCS) is believed to work best on brain cells that are active or "primed" before stimulation. The purpose of this study is to compare the effects of exercise and tDCS on memory performance in patients who have completed cardiac rehabilitation and are at risk of cognitive decline.
This Randomized Control Trial will directly compare helmet non-invasive ventilation (NIV) combined with high flow nasal oxygen (HFNO) versus HFNO alone in patients with Acute Hypoxemic Respiratory Failure (AHRF).
The purpose of this study is to characterize and compare the molecular gene expression profile in endobronchial biopsies and cells recovered in bronchial washings from study subjects who have asthma of varying disease severity and who are on maintenance inhaled corticosteroid (ICS) treatment, with that for healthy control subjects. These studies will produce transcriptomic profiles of gene expression associated with asthma disease severity. The investigators will also culture epithelial cells from study participant endobronchial brushings, including those with asthma of varying disease severity and healthy control subjects, to examine differences in the response to corticosteroids (CS) in vitro. These studies will test whether intrinsic differences exist between the responses to ICS in each group. 60 participants will be recruited with 15 of each mild, moderate and severe asthma as defined by the Global Initiative for Asthma (GINA) guidelines, as well as 15 healthy controls. Participants will undergo an initial visit to obtain informed consent, bloodwork and to assess asthma control using the Asthma Control Questionnaire (ACQ); if >1.5, ICS dose will be increased, as per GINA strategy, for a 2 week 'stabilization' phase. Repeat ACQ, spirometry and sputum induction will be performed at visit 2. Bronchoscopy will be performed at visit 3, 2-4 weeks after visit 2. Mucosal biopsies, bronchial brushings and bronchial washings will be performed and processed as per our prior methods. Mucosal biopsies will be homogenized and processed for RNA, or fixed for later sectioning and histological examination. Biopsy RNA will be assessed for quality and subjected to RNA-sequencing of all human genes (mRNA-seq). Bronchial washing cells will be collected for differential cell counting and mRNA-seq analysis. Bronchial epithelial cells (BECs) from the brushings will be cultured. BECs treated with CS and inflammatory cytokines will allow comparative assessment of BEC responses.
Measuring patient-oriented outcomes and satisfaction is important to guide meaningful changes in obstetric anesthesia care. Quality of Recovery (QoR) scores are patient rated measures, which provide a global measure of recovery after surgery. They go beyond the measure of physiological variables to include, physical, cognitive, emotive and functional outcomes. Satisfaction, in addition to QoR scores after anaesthesia is an important quality marker. Measuring satisfaction after the birth of a child is a complex and emotive subject. Understanding the factors that can influence maternal satisfaction may improve patient-centred care. Studies have shown that despite favorable clinical outcomes, many women undergoing caesarean deliveries continue to have poor experience with anaesthesia. These poor experiences go beyond inadequate pain control; many are due to poor communication with clinicians, lack of involvement in decision making, lack of provision of high quality education and information and a feeling of inadequate choice and control relating to decisions of the birth of their babies. In non-obstetric studies, satisfaction after anaesthesia has consistently been shown to be dependent on the information patient has received along with the quality of the communication and the quality of the anaesthetist-patient relationship.
