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 investigators are investigating whether the flax lignan, secoisolariciresinol diglucoside, decreases oxidative stress and inflammation. The flax seed lignan is believed to be broken down in the body to produce the health benefits of flax. Flax lignan is separated from the whole flax seed as this compound is believed to have health effects. Decreasing oxidative stress and inflammation should improve a number of the problems associated with aging. This intervention consists of 600 milligrams of the flax lignan SDG daily or an equivalent amount of whey protein. The investigators are comparing lignan to a placebo (whey powder) to examine whether a dietary intervention (i.e. flax seed containing lignan) might decrease oxidative stress and inflammation.
Currently, six Public Health Units (PHUs) in Southwestern Ontario are taking part in the developed and implementation of a social marketing intervention campaign aimed at lowering the incidence of falls to children in the home; City of Hamilton - Public Health Services (Control), Durham Public Health, Haldimand-Norfolk Health Unit, Niagara Region Public Health, Wellington-Dufferin-Guelph Public Health and Windsor Public Health (Control). This campaign is based on community-based intervention research and 'best practices' for improving parent attitudes and behaviours toward child safety. The campaign will focus on increasing parents' awareness and knowledge of fall injuries, positively impact parental attitudes to motivate them to want to implement strategies to reduce fall risks, and increase parental safety practices that would counteract the most common mechanisms that contribute to home falls for children at these young ages. The campaign will run from September 2013 through August 2014. The PHUs' social marketing campaign will strategically disseminate different materials to their respective communities: printed materials (posters, pamphlets), video modules about parenting safety, safety information through an e-Health website, and direction communication with parents through Family Health Team practitioners. The proposed research project will request archival data from Canadian Institute of Health Information (CIHI), specifically from their National Ambulatory Care Reporting System (NACRS), on frequency of falls in the home to determine the extent to which the social marketing campaign is effective. Comparing pre-, during and post-intervention levels in the PHU communities will determine if and which social marketing strategies were effective. Additionally, random digit dialing will be used to assess pre vs post parental fall related attitudes, behaviors and intervention exposure. This evaluation will provide the first ever test of a community level intervention to reduce childhood falls in the home in Canada and will provide valuable information about what constitutes 'best practices' for preventing falls in the home among children 1 through 4 years of age.
Frailty is a state of decreased physiologic reserves and vulnerability to stressors. Several tools exist to measure frailty, some based on physical tests and others on questionnaires, yet there is no agreement on which tool to recommend. This multi-center prospective cohort study is aimed at comparing various frailty assessment tools to determine which best predicts death or major complications after cardiac surgery or transcatheter intervention. The population of interest is elderly patients with severe aortic stenosis undergoing surgical or transcatheter aortic valve replacement. The frailty assessment tools under investigation include composite frailty scales, physical performance tests, muscle mass, and biomarker expression. The overall objective is to improve our ability to predict risk by measuring frailty using the optimal tool in elderly cardiovascular patients.
This open-label, multicenter, 3-period, fixed-sequence study will evaluate the effect of multiple oral doses of vemurafenib on the pharmacokinetics of a single oral dose of tizanidine in participants with BRAFV600 mutation-positive metastatic malignancies. Participants will receive a single oral dose of tizanidine on Day 1, vemurafenib orally twice daily on Days 2 to 21, and tizanidine and vemurafenib on Day 22. Eligible participants will have the option to continue treatment with vemurafenib as part of an extension study (NCT01739764).
Patients presenting with pelvic organ prolapse will be offered the use of a pessary. Vaginal estrogen cream treatment with the pessary will be randomized amongst the patients and patient satisfaction and complication rates will be assessed during follow-up.
Mannitol cream has been shown clinically to be effective for pain control. To determine if this effect is worth testing on a larger scale, 170 runners will receive a sample of 25% mannitol cream to apply on one leg, and the cream base without the mannitol on the other leg following a 10 km or longer run, and for the following five days. Mannitol and control legs will be chosen at random for each runner. Pain scores before and after cream application will be acquired each day for each leg. Means and standard deviations found will be used to determine the size of a larger study.
This is a multi-centre, open-label long-term safety study of 100 milligram (mg) mepolizumab administered subcutaneously (SC) every 4 weeks for 12 months in addition to standard of care in subjects who have severe, refractory asthma and a history of eosinophilic inflammation. Subjects who completed either MEA115588 or MEA115575 will be offered the opportunity to consent for this study.
The investigators propose a 6-month, parallel, single-blind randomized controlled trial (RCT) feasibility study of a self-management program to reduce sedentary time and increase physical activity (Sit Less to Move More) in women aged 55-70 years. The primary aim is to determine feasibility and acceptability of the intervention; and the secondary aim is to test the effect of the intervention on the primary health outcome, physical activity (mean daily step count by accelerometry) at 6 months. The investigators will also conduct an economic evaluation and a process evaluation to guide a future larger study and to inform a scaled-up implementation plan.
Ondansetron is a medication routinely given to mothers having cesarean deliveries to help prevent and treat nausea and vomiting. The investigators are studying the hemodynamic effects of prophylactic ondansetron on parturients undergoing elective cesarean deliveries under spinal anesthesia.
Background - Preoxygenation is performed before general anesthesia to increase the oxygen reserves of the body and prolong the safe period of apnea without hypoxia. However, it is often impossible to obtain a perfect face mask fit, and optimal end-tidal fractional oxygen concentration (EtO2) are not attained. The investigators designed a new oropharyngeal preoxygenation device, UMOX™, to avoid leaks during preoxygenation. In this study, the investigators compared the efficacy of UMOX™ with that of a conventional face mask. Methods - In 50 healthy volunteers breathing 100% oxygen from a circle absorber system for a 5 minute-period, the investigators compared preoxygenation using the 1) a conventional mask; 2) UMOX™ without any instruction; 3) UMOX™ with instruction on mouth breathing; and 4) UMOX™ with a nose clip, in random order. Each subject underwent all steps with a 10-minute rest period of room air breathing between each step. Inspired and end-tidal respiratory gases were measured every 10 seconds. EtO2 variation was analyzed using Anova.
