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 this study is to characterize the time course of B cell activation after allergen challenge, and more specifically measure the M1 prime related biomarkers.
Swallowing disorders (dysphagia) are common in adult patients. There is emerging evidence that dysphagia itself can cause adverse medical outcomes. There is a three-fold increased risk for pneumonia in these patients versus similar patients without dysphagia. Patients with dysphagia also suffer poor nutrition and dehydration. Patients can become so malnourished that it slows their recovery. Dysphagia can cause choking when food or liquid enters the lungs. Over time, this will cause pneumonia and even death. More acutely, patients fear that their choking will cause them to suffocate and die. Over time, patients are embarrassed to be seen choking and thus feel forced to dine alone. These patients report feelings of isolation and depression. To date, there are no practical methods to assess these adverse outcomes of swallowing difficulties in patients. This research will be the first to address this gap. Specifically, as part of previous research (PhD dissertation by RM, the PI) a new measure of medical outcomes of dysphagia was developed, titled the Medical Outcomes of Dysphagia (MOD) scale. The MOD consists of 3 subscales that each measure lung, nutrition-hydration or psychological consequences in patients with swallowing difficulties. Unlike more expensive and complex tests, the MOD has been designed for both in- and outpatients. This research will validate each MOD subscale to ensure retention of only items that are reliable and valid for use with patients who have dysphagia due to any disease etiology. The final MOD subscales will be the first to allow clinicians to track medical complications in their patients and to ensure that treatment is effective. Globally, the MOD subscales will direct limited health care resources to the most effective treatments for swallowing disorders.
Assessment of Right Ventricular Volume using the VentriPoint Medical system in patients with Tetralogy of Fallot following repair; a comparison study to cMRI. The objective of this study is: To evaluate the accuracy of the VentriPoint Medical System to calculate right ventricular volumes in patients with Tetralogy of Fallot following surgical repair. Secondary objectives are: To validate Inter and Intra observer variability at 3 clinical sites. The analyses will be the same for EDV and ESV. For either right ventricular volume, the primary effectiveness measure is the % difference between VMS and cMRI results, i.e. (VMS-cMRI)*100%/average of VMS and cMRI results. There will be two null hypotheses for the primary analysis: H0+: true mean % difference > 10% and H0-: true mean % difference < -10% The observed mean % difference will be presented with 95% confidence intervals. The VMS right ventricular volume estimates will be regarded as equivalent to cMRI estimates if both H0+ and H0- are rejected at a 1-sided 0.025 level by a paired t test for both EDV and ESV. Since H0+ and H0- cannot both be true, the total type I error rate for each measure is 0.025 and the overall type I error rate for both EDV and ESV is 0.05.
Vitamin D can be made in the skin by exposure to sunlight and can be found in certain foods. Vitamin D levels are alarmingly low in many North American children. Several health issues have been linked with low vitamin D. These include colds caused by viruses and asthma attacks. However, no study has determined whether vitamin D supplementation can reduce the risk of these conditions in young children where they are most common and most severe. The goals of this study are to determine whether wintertime high dose vitamin D supplementation of preschoolers can prevent colds and asthma attacks. The investigators also aim to work out how much money would be saved by the health care system and society if preschoolers were routinely supplemented with Vitamin D during the winter. The investigators believe that preschoolers receiving 'high dose' vitamin D supplementation during the wintertime will be less likely to have colds, asthma attacks, and low vitamin D levels and will be less likely to use the medical system and keep their parents away from work.
PREDICT Validation is a validation pharmacogenetic trial. The purpose of this study is to confirm that some genes can be used to predict how well a subject diagnosed with idiopathic growth hormone deficiency (IGHD) or turner syndrome (TS) will respond to a treatment with recombinant human growth hormone (r-hGH).
The purpose of this study is to see if testosterone solution 2% can impact symptoms of ejaculatory dysfunction in men with low testosterone.
This study is designed to determine if there is any relationship between performing an abdominal ultrasound on patients who present with hypotension and their clinical outcomes (as measured by 7, 30 day and discharge mortality).
This study aims to characterize the natural history of patients with severe perinatal or infantile onset HPP.
The TRANSIT program is a program to TRANSform InTerprofessional clinical practices to improve cardiovascular prevention in primary care. It addresses priorities in primary care relevant to the Chronic Care Model (Wagner 2001): self-management support, delivery-system design, and management of clinical information. The program includes : - a case manager to coordinate and provide care and follow up; - clinical protocols and tools to support interprofessional and systematic follow up; - training for clinicians; - patient's personalized cardiovascular health booklet; - tools to promote group sessions for patient education on cholesterol, hypertension, and diabetes. The general OBJECTIVE of this trial is to evaluate and compare two STRATEGIES for implementing the TRANSIT program in Family Medicine Groups (FMGs): 1. facilitation, and 2. passive diffusion. Passive diffusion is the usual strategy where clinicians implement an intervention program by themselves. Facilitation is a strategy whereby a facilitator provides support to a team of clinicians to help them introduce the changes required to implement the program into practice. The hypothesis is that facilitation will be more efficacious to implement the program than passive diffusion: - it will enhance the provision of cardiovascular preventive care; - it will enhance interprofessional collaboration; - it will enable more efficaciously the implementation of new clinical processes; - it will improve patient clinical outcomes; - it will cost more in the short term, but will have positive economic impact in the long term; - there will be less "undesired effects" of all types related to implementation. To test the hypothesis, we assess the efficacy of the implementation strategies to enhance interprofessional collaboration and better support patients in the management of their conditions. Impact on provision of care, interprofessional collaboration, clinical processes, and patient clinical outcomes (values, therapeutic targets, and lifestyle habits) will be evaluated. Moreover, the implementation cost related to each strategy will be estimated. We complement the trial with qualitative methods to document the perceptions of clinicians, facilitators, patients and members of the family regarding the TRANSIT program, the implementation strategies and the observed changes in the clinical practices and outcomes.
