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.
Osteoarthritis (OA) affects approximately 10% of people older than 60 years, and compromises the quality of life of more than 21 million North Americans. Studies on the use of complimentary and alternative medicines have reported that OA patients in the US are among the highest users of CAM. Previous studies on a unique natural mineral product SierraSil® demonstrated an improvement in joint health and function in subjects with mild to moderate OA of the knee. Extracts of Sierrasil® are reported to reduce cartilage degradation in response to IL-8 and nitric oxide production suggesting an ability to suppress IL-8 mediated events in human cartilage. The primary objective is to assess the efficacy of SeirraSil Joint Formula versus placebo on the symptoms of osteoarthritis as assessed by WOMAC™ Osteoarthritis Index Pain subscale in subjects with osteoarthritis of the knee.
Use of oral contraceptives (OCs) reduces a woman's risk of ovarian cancer very significantly and the protective effect continues for at least 25 years after use of OCs is stopped; the mechanisms of how this occurs are not understood. We are proposing here to directly study the effect of OCs on the fallopian tube and inclusion cysts within the ovary - sites from which most ovarian cancers are thought to arise - in order to better understand the mechanistic basis for OC protection against ovarian cancer. We think the protection results from reduced cell proliferation. It will lay the foundation for further studies to ensure that the protection against ovarian cancer afforded by 'traditional' OCs is not lost with alterations in OC formulation, and, if possible, to guide development of OC formations to improve further on the protection afforded by OCs.
The purpose of this study is to evaluate the association between genetic factors and response to treatment (guselkumab, ustekinumab, adalimumab, or etanercept) and psoriasis (scaly skin rash).
This is a pilot study in a randomized, controlled, double-blinded format and will evaluate the ability of a local anesthetic, Ropivacaine, to decrease pain after gastric bypass surgery. The drug will be administered into the abdomen during a bariatric bypass surgery. After surgery, patients who received Ropivacaine will be compared to those without Ropivacaine to determine its effect on reducing pain, recovery of lung function, ability to walk, and quality of life during recovery.
Chronic rhinosinusitis (CRS) is a common sinus and nasal condition affecting more than 33 million Americans. The treatment of CRS typically begins with maximal medical therapy however, when this fails to improve patient symptoms, surgical intervention is considered. Endoscopic sinus surgery (ESS) is a well-established treatment for refractory CRS with approximately 600,000 sinus surgeries performed annually in the United States alone. Despite the success of this intervention, up to 26% of patients experience complications following surgery, including middle meatal (MM) synechiae, edema, polyp recurrence, and middle turbinate lateralization. Currently, there is no consensus as to the postoperative care regime that is most effective at minimizing or preventing these potential complications. Therefore there is need for further study into the role of debridement, examining patients undergoing endoscopic sinus surgery while concurrently addressing the potential confounders of maximal medical therapies in the postoperative setting. This prospective, randomized, single-blind, controlled study design will investigate the efficacy of postoperative debridement following ESS. Patients who have undergone ESS will have one nare randomized to debridement and the other to no debridement at the first week post-operative visit. In this way, the patients will act as their own controls in order to account for inter-patient variability in disease severity. The primary outcome will assess synechiae formation attributed to ESS. Secondary outcomes will include pain (side-specific) attributed to the debridement procedure as well as comparing pre and post endoscopy scores and SNOT-22 questionnaire responses.
Mechanical ventilation is a vital therapeutic support, widely used in pediatric intensive care. Invasive ventilation (IV) is associated with risk of major complications ( nosocomial pneumonia, secondary pulmonary barotrauma injuries, pneumothorax) , which can increase : the duration of ventilation, mortality, length of ICU stay and health costs. The practitioner should ask the benefit of the continuation of this IV daily and adapting it, to limit complications. The evaluation of the work of breathing is a key element in understanding the pathophysiology of respiratory distress but is also a key element in improving the management of ventilatory support and the adjustment of ventilatory parameters . It has been shown that there is an increased work of breathing in all children admitted in ICU for clinical acute respiratory distress that is significantly reduced by ventilatory support. There is probably a relationship that should be proportional between the work of breathing ( PTP ) resulting in respiratory request triggered by the respiratory drive and the electrical activity of the diaphragm ( Edi ) . The validation of this correlation PTP / Edi has a direct impact on the monitoring of ventilated patients with the ability to monitor the physiological factor while maintaining a classical treatment of children by simply monitoring Edi without additional invasive device .
This screening and multi-sub-study randomized phase II/III trial will establish a method for genomic screening of similar large cancer populations followed by assigning and accruing simultaneously to a multi-sub-study hybrid ?Master Protocol? (S1400). The type of cancer trait (biomarker) will determine to which sub-study, within this protocol, a participant will be assigned to compare new targeted cancer therapy, designed to block the growth and spread of cancer, or combinations to standard of care therapy with the ultimate goal of being able to approve new targeted therapies in this setting. In addition, the protocol includes a ?non-match? sub-study which will include all screened patients not eligible for any of the biomarker-driven sub-studies. This sub-study will compare a non-match therapy to standard of care also with the goal of approval.
The purpose of this study is to compare the clinical performance of the Ultrashape system with VelaShape II device for reduction of the waist.
The Canadian Respiratory Research Network (CRRN) has recently been established to study the origins and evolution of airways disease in the population. The CRRN is funded by the Institute of Cardio-respiratory Health (ICRH), an institute of the CIHR. The Physiology platform will support the other CRRN platforms (biology, imaging, population health, knowledge transfer) by providing a comprehensive characterization of the nature and extent of physiological impairment of respiratory function in smokers at risk for airways disease and in those with early or mild airway obstruction. The planned studies of the physiology group (core sites located at Queen's University, University of British Columbia and McGill University) will initially focus on smoking-related lung injury in those at risk for COPD and in those meeting spirometric criteria for mild airway obstruction, with or without respiratory symptoms. The primary aim of this initial study is to identify and validate sensitive test(s) of peripheral airway dysfunction that may qualify as physiological biomarkers for use in future CRRN studies.
Tics are brief repetitive movements or vocalizations. Gilles de la Tourette's syndrome (TS) is a disorder characterized by recurrent motor and vocal tics. Tourette syndrome and tic disorders affect up to 8% of children. Peak severity of tic disorders occurs between the ages of 8 to 12 years, therefore during childhood and adolescence the most significant impacts are felt. The quality of life of young people with tics is lower than their peers' and tic severity predicts lower quality of life. Studies have also shown negative social perception toward children with tics. Approximately 50% of patients with Tourette syndrome will have other diagnoses including attention deficit hyperactivity disorder (ADHD), obsessive compulsive disorder, anxiety and depression. Studies have shown improvements in ADHD with physical activity. ADHD and tic disorders are thought to involve the same areas of the brain; thus it is possible that tics might also improve with physical activity. However, no studies to date have examined this. The investigators predict that by implementing a motivational physical activity program, in conjunction with physical activity counseling, the investigators will be able to increase levels of physical activity in children with tics and Tourette syndrome, with a positive impact on tic severity.
