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.
Hypothesis: The investigators hypothesize that the current oral protocol is sub-optimal and an enhanced protocol will decrease the incidence of hospital acquired pneumonia (HAP)in the acute, non-intubated, care-dependent, neurologically impaired, adult patient.
Dexmedetomidine is a sedative drug that has many benefits when given to children under anesthesia, such as improved pain relief and reduced agitation following their surgery. It is usually given as an intravenous infusion over 10 minutes, to avoid the changes in heart rate and blood pressure that are occasionally seen when it is administered more quickly. However, this is often infeasible and usually inconvenient. The investigators aim to determine the dose of dexmedetomidine that can be given rapidly (over 5 seconds) without causing significant changes in heart rate and blood pressure. This will be the only study specific intervention.
Bronchiolitis is a common illness of the respiratory tract caused by infection of the tiny airways within the lungs called bronchioles. At present the standard care of hospitalized children with bronchiolitis is oxygen via nasal prongs. In this study the investigators would like to compare standard ward management with a new method of delivering oxygen called high flow nasal cannula oxygen therapy (HFNOT). HFNOT involves breathing warmed, moistened oxygen through nasal cannulae at a flow rate of 8 liters/minute. Accumulated experience suggests that HFNOT eases the child's work of breathing and reduces need for ICU admission and invasive respiratory support.
Collect and evaluate the long term safety data.
This study was to assess the safety and efficacy of sofosbuvir (GS-7977; PSI-7977) in combination with ribavirin (RBV) administered for 12 weeks compared with pegylated interferon (PEG)/RBV administered for 24 weeks in treatment-naive patients with Hepatitis C (HCV) genotype 2 or 3. Efficacy was assessed by the rate of sustained viral response (SVR) 12 weeks after the discontinuation of therapy (SVR12). This was a non-inferiority study, and if non-inferiority was demonstrated, the study was then allowed to test for superiority.
The Problem Distal radius fractures (DRF) are common and result in a variable amount of disability. The investigators have completed considerable work in developing tools that measure impairment and disability after DRF . The investigators initial studies indicate that the associated disablement process is multifactorial and variable with only 25% of the resultant disability predicted by baseline patient and injury characteristics. The investigators see DRF as a signal event where some people are at-risk of transitioning from an active lifestyle to inactivity and subsequent health risks. The investigators recent data confirms variable participation following a DRF. The traditional focus in orthopedic/rehabilitative approaches to DRF fracture management has been localized to the wrist, largely ignoring this potential transition and its health impacts. The investigators will initiate a line of investigation that will profile the at-risk older adult who presents with a DRF with the ultimate goal of accurate identification and prevention of adverse activity transitions (active to inactive). In this study the investigators will identify the extent of the problem by quantifying changes in activity/participation and its short-term health impacts. The investigators will also identify the risk factors present at time of injury that predict a loss of mobility/activity/participation. This work has the potential to identify tools and/or clinical prediction rules that identify at-risk individuals at a critical time where early intervention might most easily prevent adverse outcomes associated with inactivity.
The purpose of this study is to evaluate the utility of the S-STREAM as an instrument to assess motor function in subjects who have experienced a nonhemorrhagic ischemic stroke.
The aim of this research project is to compare electrocautery to scalpel for laparotomy skin incisions, with the following objectives: 1. To investigate whether electrocautery produces a cosmetically inferior surgical scar. 2. To compare the rates of wound infection with each technique. 3. To determine if electrocautery results in less postoperative pain. Our null hypothesis is that electrocautery is equivalent to scalpel for creating skin incisions; with respect to wound cosmesis, wound infection rate, and post-operative pain.
Iodine-123 labelled ortho-Iodohippuric Acid ([I-123]-OIH) was used in the early 1970's as a kidney imaging agent or tracer that "lights-up" inside your body when scanned, but over the years its use has declined. The most commonly used tracer is Technetium-99m labelled Mercaptoacetyltriglycine ([Tc-99m]-Mertiatide or [Tc-99m]-MAG3). However, long-term shortages may threaten the supply of the radioactive substance Tc-99m in Canada and the world. As a result of such shortages, there is a need to identify other types of tracers that can be used for imaging. [I-123]-OIH may be an alternative. The purpose of this study is to examine the diagnostic performance characteristics of [I-123]-OIH in comparison to [Tc-99m]-MAG3.
The Canadian population, as is the case in most developed countries, is ageing and becoming increasingly overweight and/or obese. Both ageing and obesity are associated with reduced cognitive performance which can impact adversely on the ability to undertake daily activities and increases the risk of loss of independent living and reduced quality of life. The investigators predict that consumption of ½ cup of pulses per day for 12 weeks will improve cognitive function in older overweight/obese adults and thus decrease the rate of cognitive decline that occurs in this at-risk population.
