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.
Childhood arthritis is an important cause of pain for affected children and youth (adolescents). Many youth with arthritis also have trouble sleeping. They often struggle to sleep through the night, wake up earlier, and are sleepier during the day compared to healthy children. Our research group, among others, has shown a strong link between sleep and pain. The main purpose of this study is to assess the impact of changing sleeping patterns on pain, and disease activity, in teenagers with arthritis. We think that better sleep will directly lead to better health.
This study will test the effectiveness of a brief educational intervention that teaches youth that they can grow and change, known as "growth mindset." Similar growth mindset interventions have improved youths' well-being and academic skills, and reduced risk for depression. In this study, youths' depressive symptoms and well-being will be measured before the intervention and then again 4 months after the intervention to determine if the intervention had a positive impact for youth experiencing transitions (firs and last years of high school).
To establish the safety and effectiveness of the Boston Scientific Cardiac Cryoablation System for treatment of symptomatic, drug refractory, recurrent, paroxysmal atrial fibrillation (AF).
Children with cancer are vulnerable to symptoms of anxiety and depression. Although screening for psychosocial distress is a standard of care for children with cancer, there is a limited knowledge
Obesity and diabetes are linked to increased risk for health problems such as heart attack, stroke, and death. At the cellular level, obesity and diabetes increase levels of harmful inflammatory cells (M1 macrophages) and decreases levels of protective stem cells (circulating progenitor cells) in the blood. Bariatric (weight loss) surgery is an effective treatment that leads to significant weight loss and improved health in patients with obesity. However, it is unknown if weight loss surgery also replenishes healthy stem cells and decreases inflammatory cells in the body. Therefore, the purpose of this research study is to compare levels of these stem and inflammatory cells before and after bariatric surgery, and to compare to a control group of healthy normal weight participants. The investigators anticipate that inflammatory cell levels will be reduced and stem cell levels and function will be restored after bariatric surgery, similar to levels of healthy normal weight individuals.
A broad range of prognostic and predictive tools are available for patients with newly diagnosed early stage breast cancer. These range from free and publicly available mathematical algorithms, through to expensive genomic tests. It is not known how the use of these different scores affects physician decision making with respect to ordering genomic tests, nor how well these algorithms predict for the results of Oncotype DX ® in the real-world setting. This pragmatic study will help to answer these questions.
Previous work of the investigators demonstrated the anti-obesity and anti-steatosis potential of the Amazonian fruit camu-camu (CC) in a mouse model of diet-induced obesity [1]. It was demonstrated that the prebiotic role of CC was directly linked to higher energy expenditure stimulated by the fruit since fecal transplantation from CC-treated mice to germ-free mice was sufficient to reproduce the effects. The full protection against hepatic steatosis observed in CC-treated mice is of particular importance since nonalcoholic fatty liver disease (NAFLD) is one of the most common causes of chronic liver disease. Thirty percent of adults in developed countries have excess fat accumulation in the liver, and this figure can be as high as 80% in obese subjects. NAFLD is an umbrella term encompassing simple steatosis, as well as non-alcoholic steatohepatitis which can lead to cirrhosis and hepatocellular carcinoma in up to 20% of cases. Up to now, except for lifestyle changes, no effective drug treatment are available. Previous work has suggested that CC possesses anti-inflammatory properties and could acutely reduce blood pressure and glycemia after a single intake. While CC could represent a promising treatment for obesity and fatty liver, no studies have thoroughly tested this potential in humans. Therefore, a robust clinical proof of concept study is needed to provide convincing evidence for a microbiome-based therapeutic strategy to counteract obesity and its associated metabolic disorders. The mechanism of action of CC could involve bile acid (BA) metabolism. BA are produced in the liver and metabolized in the intestine by the gut microbiota. Conversely, they can modulate gut microbial composition. BA and particularly, primary BA, are powerful regulators of metabolism. Indeed, mice treated orally with the primary BA α, β muricholic (αMCA, βMCA) and cholic acids (CA) were protected from diet-induced obesity and hepatic lipid accumulation. Interestingly, the investigators reported that administration of CC to mice increased the levels of αMCA, βMCA and CA. Primary BA are predominantly secreted conjugated to amino acids and that deconjugation rely on the microbial enzymatic machinery of gut commensals. The increased presence of the deconjugated primary BA in CC-treated mice indicate that a cluster of microbes selected by CC influence the BA pool composition. These data therefore point to an Interplay between BA and gut microbiota mediating the health effects of CC. Polyphenols and in particular procyanidins and ellagitannins in CC can also be responsible for the modulation of BA that can impact on the gut microbiota. Indeed, it has been reported that ellagitannins containing food like walnuts modulate secondary BA in humans whereas procyanidins can interact with farnesoid X receptors and alter BA recirculation to reduce hypertriglyceridemia. These effects are likely mediated by the remodeling of the microbiota by the polyphenols. In accordance with the hypothesis that the ultimate effect of CC is directly linked to a modification of the microbiota, fecal transplantation from CC-treated mice to germ-free mice was sufficient to recapitulate the lower weight gain and the higher energy expenditure seen in donor mice.
After anterior cruciate ligament (LCA) rupture, the recommended treatment for athletes is the surgical reconstruction of the ligament (ACL-R), followed by a long rehabilitation period. The results of this treatment are sub-optimal with a low rate of return to pre-injury level of sport, a high risk of reinjury and early knee osteoarthritis. To improve treatment outcomes, researchers and clinicians recommend optimizing rehabilitation protocols. They recommend individualizing rehabilitation progression based on objective criteria. However, current defined criteria relied on experts' opinions and not scientific validation. Return to run after ACL reconstruction is an important rehabilitation milestone. It often means the beginning of the return to sport continuum. A successful return to run is therefore crucial for both the patient and clinician. In this study, the investigators aim to determine the predictive outcomes for a successful return to run after ACL-R.
