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.
Obesity is very common worldwide and breathing problems at night (obstructive sleep apnea, OSA) are common in obesity. Despite the best treatment, obesity and OSA are linked to early death from heart problems. They are also associated with lower levels of physical activity. Exercise strategies for weight loss, increasing physical activity and improving fitness are needed for obesity. In Obese individuals with OSA 1. The investigators will compare corridor walking tests compared to laboratory exercise tests. The null hypothesis is that the peak oxygen uptake achieved and the cardiopulmonary response during both the six-minute walk test and Incremental Shuttle Walk Test would not be different from that observed during an Incremental Treadmill Test. 2. The investigators will investigate whether cycling or walking uses more calories for the same intensity. We hypothesise that cycling (weight supported) will be endured for long. 3. The investigators will compare commonly used exercise tests with levels of daily physical activity. The information from these three projects will help us set up the optimal exercise program for obese individuals.
The purpose of this study is to determine whether is is feasible and acceptable to deliver a telephone based coaching intervention compared with education alone in community dwelling older adults (age 60 and older) after a fall related hip fracture.
The HEMO-TIN trial is designed to look at both the safety (bleeding risk) and effectiveness (clotting risk) of tinzaparin compared with unfractionated heparin for anticoagulation in hemodialysis patients.
Modeling of bicarbonate within the dialysate fluid, specifically a lower than standard concentration has been suggested in facilitating the removal of phosphate and potassium. To test this hypothesis, the study will use a cross-over study design to evaluate phosphate and potassium removal during dialysis by altering bicarbonate concentration in dialysis fluid (i.e. high bicarbonate, standard bicarbonate washout, low bicarbonate), and compare the effects of the different dialysate bicarbonate concentrations on the removal of phosphate and potassium during hemodialysis
Closed-loop strategy is composed of three components: glucose sensor to read glucose levels, insulin pump to infuse insulin and a dosing mathematical algorithm to decide on the required insulin dosages based on the sensor's readings. A dual-hormone closed-loop system would regulate glucose levels through the infusion of two hormones: insulin and glucagon. The objective is to compare the efficacy of single-hormone closed-loop strategy and dual-hormone closed-loop strategy at regulating glucose levels during continuous exercise and interval exercise. The investigator hypothesized that dual-hormone closed-loop strategy is superior to single-hormone closed-loop strategy in regulating glucose levels during exercise periods.
Closed-loop strategy is composed of three components: glucose sensor to read glucose levels, insulin pump to infuse insulin and a dosing mathematical algorithm to decide on the required insulin dosage based on the sensor's readings. A dual-hormone closed-loop system would regulate glucose levels through the infusion of two hormones: insulin and glucagon. The objective of this project is to assess whether a dual-hormone closed-loop strategy would alleviate the burden of carbohydrate counting from patients with type 1 diabetes (T1D) without a significant degradation in post-meal glucose control. Our primary hypothesis is that meal-announcement strategy (pre-meal CHO-independent bolus) is equivalent to meal-and-carbohydrate-announcement strategy (full CHO-matching bolus) during closed-loop regulation of glucose levels in adults with T1D. Our secondary hypothesis is that closed-loop strategy with meal-announcement strategy (pre-meal CHO-independent bolus) or meal-and-carbohydrate-announcement strategy (full CHO-matching bolus) is better than conventional pump treatment in regulation of glucose levels in adults with T1D.
This prospective hybrid longitudinal study was conducted in the United States (US), Canada, the United Kingdom (UK), and Germany. To obtain the most complete and comprehensive understanding of the burden of opioid-induced constipation (OIC) in these countries, this study used a combination of web-based, longitudinal patient survey, retrospective data abstraction from medical records, and a prospective physician survey. The primary objective of this study was to estimate the rate of inadequate response to laxatives (LIR), which was defined as having sufficient laxative use (at least one laxative use ≥ four times per reference period), and inadequate response (defined as fewer than three bowel movements (BMs) OR at least one of the following symptoms on the Patient Assessment of Constipation Symptoms (PAC-SYM) measure scored as moderate, severe or very severe: BMs too hard, straining to have a BM, feeling like you didn't "finish" a BM, and feeling like you had to pass a BM but could not), in a cohort of non-cancer pain and cancer pain (separately) participants with OIC, by country and overall. The secondary study objectives are as follows: 1. To estimate the rate of LIR for two subgroups: 1xLIR and 2xLIR. 1xLIR was defined as use of at least one laxative agent ≥ 4 times in the reference period while 2xLIR was defined as the use of at least two laxative agents, each used ≥ 4 times in the reference period; 2. To describe the baseline demographic and clinical characteristics, including prior health status, comorbidities, constipation-related GI symptoms, and concomitant medications of patients with OIC; 3. To describe drug utilization and self-management of OIC; 4. To describe the pre-index and post-index healthcare resource utilization and estimate costs associated with the diagnosis, treatment, and general management of OIC (including laxative use) and events attributed to OIC, including both direct and indirect costs; 5. To describe patient-reported impact of OIC on health-related quality of life, productivity, and pain management; 6. To describe patient-reported treatment satisfaction with laxative use; and 7. To describe physician-reported awareness of OIC and symptoms and understanding of patient-reported impact of OIC.
The purpose of this study is to evaluate the effectiveness of paclitaxel-coated balloon catheter to prevent restenosis after PTA (percutaneous transluminal angioplasty) of hemodialysis access (HA) in comparison with the uncoated PTA balloon catheter.
To study the safety and efficacy of the combination of BGJ398 with BYL719 in patients whose tumors express mutations to PIK3CA with or without alterations to FGFR 1-3.
The main objective of the study is to assess the efficacy of an antioxidant in preventing pigmentation induced by visible light in subjects with a phototype IV or V. Patients will be exposed to a range of visible light to areas on the back to confirm study eligibility. Patients showing pigmentation after 7 days on the exposed areas will be eligible to continue. Eligible patients will have study product applied to part of the back and placebo on another part of the back. The placebo area will be exposed to the same range of light based as at Day -7. The area where the antioxidant is applied will have a higher range of light exposure than the area without the study product. Seven days later, the areas will be examined to determine the lowest exposure inducing pigmentation on the sides with placebo and with antioxidant. The color will also be measured between two identical exposures with placebo and with antioxidant.
