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.
Overview: The application of gel sheets holds promise for both the prevention and treatment of hypertrophic scar after deep dermal injuries. Although some positive results have been published, a Cochrane review of the data concluded that the trials were of poor quality therefore only provided weak evidence for their benefit. One of the limitations of previous studies has been the subjectivity and potential bias of the evaluation tools that were used. The validation of electronic instrumentation for the measurement of hypertrophic scar and determination of their superior clinometric properties provides the basis from which precise, systematic, evaluations can now be performed that will allow for confident conclusions to be made. Thus, the objective of this study is to evaluate the efficacy of a non-silicone gel sheet relative to a patient-matched control site in a prospective, randomized, controlled, within-patient study. This study has been piloted and the data used to establish the number of participants that will be required for an adequately powered study. Specific Objectives: 1. To characterize the changes in vascularity, thickness, pain and itch in adult burn hypertrophic scar (HSc) following an extended course of treatment with a non-silicone based gel sheet relative to matched control scars. 2. To characterize the changes in pliability of adult burn HSc following an extended course of treatment with a non-silicone based gel sheet relative to matched control scars. Recruitment: Burn survivors aged 14 years and more, who have developed HSc and are being treated at CHUM and Villa Medica Rehabilitation Hospital. Risks: There is a minimal risk that the gel used in this project might cause minor redness (10-25% if the use instructions are not followed). The rash quickly resolves once the gel sheet is removed. Study Site: This study will be carried out at Villa Medica Rehabilitation Hospital.
Virtual Surgical Planning (VSP), where 3D modeling is used to create 3D-printed surgical guides, has been shown to improve outcomes for patients who undergo mandibular reconstruction surgery, usually due to invasion of cancer from the oral cavity to the jaw. This trial will directly compare the outcomes of patients who receive VSP versus patients who receive the current standard of care, which is Free-Hand Surgery (FHS). They will be randomized into either treatment at a 1:1 ratio and bony union rates will be compared between 12-month postoperative CT scans for each treatment group. Secondary objectives include comparing other short and long-term complication rates, reconstruction accuracy, quality of life, and functional outcomes of VSP and FHS. An economic analysis of VSP will also be performed.
This trial will compare two management strategies for HF patients with Atrial Fibrillation. The active control group will undergo BiV pacing, followed by an AV node ablation. The experimental group will undergo LBBAP, followed by an AV node ablation.
In the randomized controlled DRAGON 2 trial study subjects will be randomized between two arms, PVE alone (control group) and PVE/HVE (interventional group).
Neurally Adjusted Ventilatory Assist (NAVA) is a mode of ventilation where the electrical activity of the diaphragm (EDI) - a signal representing the baby's respiratory drive - is used to control the timing and amount of assist provided. NAVA was introduced to the market in 2007 and since has been used in more than 40 countries. In the current clinical practice, the Edi signal from the patient is captured with miniature sensors (the size of a hair) embedded in the wall of a specially designed naso/orogastric feeding tube. This FDA and Health Canada approved, commercially available catheter (Getinge, Solna, Sweden), is 6 Fr in size (outer diameter), 49 cm in length and has 8 pairs of sensors that are placed 6 mm apart (so-called inter electrode distance (IED) is 6 mm). While no obvious side effects have been noted by clinicians, for the smallest of neonates, the currently used commercial catheter (size 6F, 49 cm long) may have 'excessive' post-array catheter length. In these neonates, typically those with weight < 750 grams, following the correct placement of catheter as per the electrode array positioning at gastro-esophageal junction, the feeding holes in the catheter may end at the level of distal stomach instead of the desirable mid-stomach location. The changing demographics of the patients in the Neonatal Intensive Care Units (NICU) has created a clinical need to redesign the currently used Edi catheter specifically to suit the smallest of patients, such that following adequate placement the feeding holes sit at the level of mid-stomach. Drs. Christer Sinderby and Jennifer Beck in Toronto, Canada, are the original designers of the 6 mm/49 cm currently used Edi catheter. These investigators (at St-Michael's Hospital, Toronto) in collaboration with their team at Neurovent Research Inc. (NVR) have re-designed and invented a new prototype of the current FDA-approved catheter specifically suited for use in extreme premature neonates. They have done so by reducing the interelectrode distance from the originally set 6 mm to 4 mm, which reduces the overall insertion depth to capture the same signal from the diaphragm. All other parameters are exactly same as the original catheter (6F, 49 cm long). In this small feasibility study the investigators wish to provide a clinical proof of concept for the use of this newly designed prototype in 10 extremely premature neonates who are already receiving NAVA ventilation in the NICU.
The Canadian CABG or PCI in Patients With Ischemic Cardiomyopathy (STICH3C) trial is a prospective, unblinded, international multi-center randomized trial of 754 subjects enrolled in approximately 45 centers comparing revascularization by percutaneous coronary intervention (PCI) vs. coronary artery bypass grafting (CABG) in patients with multivessel/left main (LM) coronary artery disease (CAD) and reduced left ventricular ejection fraction (LVEF). The primary objective is to determine whether CABG compared to PCI is associated with a reduction in all-cause death, stroke, spontaneous myocardial infarction (MI), urgent repeat revascularization (RR), or heart failure (HF) readmission over a median follow-up of 5 years in patients with multivessel/LM CAD and ischemic left ventricular dysfunction (iLVSD). Eligible patients are considered by the local Heart Team appropriate and amenable for non-emergent revascularization by both modes of revascularization. The secondary objectives are to describe the early risks of both procedures, and a comprehensive set of patient-reported outcomes longitudinally.
Iliotibial band syndrome (ITBS) is a condition frequently treated in physiotherapy. The pathophysiology underlying this syndrome is still poorly understood. Ultrasound makes it possible to evaluate the morphology and to quantify, with sonoelastography (SWE), the stiffness of the iliotibial band (ITB). The objective is to determine the feasibility of a cross-sectional study aimed at evaluating the morphometry and stiffness of the ITB in runners with and without a diagnosis of ITBS. Socio-demographic and clinical data will be collected and ultrasound measurements (thickness and stiffness) of the iliotibial band will be performed in supine with the knee positioned at 2 different angles (0° and 30° flexion). Variables such as the recruitment rate/month, the inclusion/exclusion rate, the acceptability of the procedure will be used to characterize the feasibility. The relationship between ultrasound measurements and clinical outcomes will be explored. The results obtained will document feasibility issues and provide preliminary results will lay the groundwork for a large scale study.
CANTOR SING is a pilot single center double blinded randomized study. The investigators will compare the effect of canagliflozin (300 mg daily - intervention arm) vs. placebo (control group) on the FDG aortic uptake in patients with stable CAD (over 60 days post-myocardial infarction) after a 6-month period of treatment. The investigators plan to enroll 8 patients in each arm (total sample size: 16 patients). Primary endpoint is the change in FDG aortic uptake between baseline and 6 months in each arm.
