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.
Trauma patients are at a high risk of developing blood clots in the legs (deep vein thrombosis - DVT), which can travel to the lungs and cause serious health consequences. Often, these patients cannot receive blood-thinning medication to prevent these blood clots because of the risk of bleeding; in this case, they are usually given intermittent pneumatic compression devices (IPCs) to prevent blood clots. IPCs are inflatable sleeves that fit over the legs and periodically inflate and deflate, helping to pump blood out of the legs and thus reduce the risk of blood clot formation. Several studies suggest that IPCs are working properly on the patient only 60-70% of the time. Some patients also find them uncomfortable. A new device (geko) that works by stimulating the leg muscles and increasing blood flow in the legs has recently been developed. To compare the geko with IPCs, this study will randomly assign trauma patients who cannot receive blood thinners for blood clot prevention to either IPCs or geko. The main goal is to determine the feasibility of doing a larger study which would compare the efficacy of these devices in preventing blood clots. The amount of time the devices are properly used on the patients, comfort and tolerability, development of blood clots, and blood flow in the leg veins and arteries will also be measured and compared between the devices.
Ingestion of sodium citrate (Na-Cit), an alkalizing agent, increases extracellular pH via liver oxidation by decreasing [H+] and increasing bicarbonate concentration (HCO3-). Studies have confirmed that increasing extracellular pH promotes the efflux of La- and H+ from active muscles. This is due to an increase in activity of the pH sensitive monocarboxylate transporter as the gradient of intracellular versus extracellular H+ increases. Therefore, artificially inducing alkalosis prior to anaerobic exercise may reduce intracellular acidosis and increase the time to fatigue - defined as a decrease in force production with an increased perception of effort. The investigators will test the null hypothesis that sodium citrate ingestion (chronic and acute) will not have an effect on exercise performance compared to placebo.
To evaluate whether Prostatic Artery Embolization (PAE) might be an effective alternative treatment option for benign prostatic hyperplasia (BPH), in comparison to current gold standard surgical treatment- Transurethral Resection of Prostate (TURP).
Parkinson's disease is caused by a reduction of dopamine causing motor deficits. The investigators are studying how exercise can help PD patients by increasing dopamine release in an area of the brain that coordinates movement, the striatum. The investigators will enroll PD patients into two groups; one group will complete a 12-week aerobic exercise program and the other will complete a 12-week control program including yoga and stretching only. The investigators will measure changes in dopamine release before and after either 12-week intervention. Subjects will complete motor and cognitive questionnaires in addition to functional magnetic resonance imaging and positron emission tomography neuroimaging.
The objective of this study is to evaluate the pharmacokinetics of deferiprone and its 3-O-glucuronide metabolite following administration of a single 1500 mg dose of Ferriprox in patients with sickle cell disease.
This trial is conducted in Asia, Europe and North and South America. The aim of the trial is to investigate the efficacy and safety of insulin degludec/insulin aspart once daily plus insulin aspart for the remaining meals in children and adolescents with type 1 diabetes mellitus.
This randomized phase II trial studies how well cabozantinib-s-malate works compared with temozolomide or dacarbazine in treating patients with melanoma of the eye (ocular melanoma) that has spread to other parts of the body and cannot be removed by surgery. Cabozantinib-s-malate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as temozolomide and dacarbazine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether cabozantinib-s-malate works better than temozolomide or dacarbazine in treating patients with melanoma of the eye.
To assess the potential of the cerebral oximeter to measure placental oxygenation
This study will evaluate bimatoprost 0.01% (LUMIGAN® RC) in patients with elevated intraocular pressure (IOP) due to primary open angle glaucoma (POAG) or ocular hypertension (OHT) in a clinical setting.
In a previous study conducted within the Center for Musculoskeletal Research (CMR) on Total Hip Arthroplasties (THA), it was determined that the investigators could simultaneously capture in vivo sound and motion of the femoral head within the acetabular cup during weight-bearing activities for subjects implanted with either a metal-on-polyethylene (MOP), metal-on-metal (MOM) or ceramic-on-ceramic (COC) THA. This was the first study to apply sound analysis as an impulse excitation technique for testing hip conditions and for measuring femoral head sliding in the acetabular component of human hip joints by acoustic means. Unfortunately, no studies have been conducted to compare the in vivo kinematics and sound for subjects implanted using various surgical approaches. It could be hypothesized that subjects having various surgical approaches could lead to an increase or reduction of in vivo hip separation. Therefore, the objective of this study is to analyze a total of 30 subjects implanted with either an anterior (10 patients), anterior-lateral (10 patients), or posterior-lateral (10 patients) surgical approach to determine if any of these surgical approaches leads to less or more in vivo hip separation. All subjects will be analyzed under in vivo weight-bearing conditions using video fluoroscopy to determine in vivo motion.
