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.
There are over 44,000 persons living with spinal cord injury (SCI) in Canada, who face substantial challenges in maintaining a healthy body composition after injury. As a result, obesity, diabetes and cardiovascular disease are prevalent in this population. Guidelines indicating that twice weekly 20-minute sessions of exercise (plus resistance training) will increase physical fitness in those with SCI have been recently published. However, no SCI-specific guidelines indicating the volume of exercise to reduce the risk of developing obesity-related diseases exist. Longitudinal studies indicate that a weekly exercise-related energy expenditure of 2000 - 2500 Calories is correlated with the least likelihood of cardiovascular disease in the able-bodied population. There is little information regarding energy expenditure (EE) for activities carried out by persons with SCI, with less available for persons with tetraplegia. Once known, this EE data can be used to develop exercise interventions to determine the volume of voluntary exercise required to reduce obesity and risk factors for diabetes and cardiovascular disease in those living with tetraplegia.
Uncomplicated sigmoid diverticulitis is a common disease in Western countries. Traditional management includes inpatient administration of either oral or intravenous antibiotics with resumption of oral intake as symptoms improve. Recent literature has however questioned both inpatient and antibiotic treatment. Indeed, both inpatient and antibiotic treatment are associated with non-negligible risks to patients. The aim of this trial is to assess the feasibility of a randomized controlled trial designed to determine whether nonantibiotic treatment of uncomplicated diverticulitis is safe in the outpatient setting.
Bupivacaine is a local anesthetic commonly used to manage postoperative pain. Liver resection patients typically have an epidural catheter placed preoperatively through which they receive a continuous infusion of bupivacaine and hydromorphone for up to 5 days postoperatively. The liver metabolizes bupivacaine, and produces proteins that bind with bupivacaine to take it out of circulation and thereby reduce its toxicity. Because a portion of the liver is being removed due to pre-existing liver disease, investigators hypothesize that liver resection patients have an impaired ability to clear bupivacaine from circulation that may increase their susceptibility to bupivacaine toxicity. To assess this, investigators will measure free and bound bupivacaine in liver resection patients postoperatively to determine whether bupivacaine reaches toxic levels. Investigators will also quantify binding protein levels to determine if these levels are reduced after surgery, which could contribute to the elevated bupivacaine levels in these patients. Finally, investigators will monitor patients for signs and symptoms associated with bupivacaine toxicity.
Problem Suction drains during TKA present certain costs to the health system and requires additional nursing care. There is no clear evidence that supports their use, and no studies so far have compared blood loss in patients with or without drains when TA is administered during TKA. Hypothesis During total knee arthroplasty, the postoperative blood loss, measured by hemoglobin level, will be lower when no drains are used. Method - Randomized controlled trial - Monocentric, 3 surgeons - Randomisation by sealed envelopes
The immune response against tumors can be highly effective in preventing tumor development, growth and metastasis under certain circumstances. However, tumor associated immune suppression can profoundly limit the impact of natural tumor immunity and also reduce the effectiveness of tumor immunotherapy strategies. A major component of tumor associated immune suppression is mediated by myeloid cells, especially the monocytic subset of myeloid derived suppressor cells (MDSC). In recent studies that were conducted through a CCSRI Innovation grant, the investigators discovered that oral treatment of mice with the commonly used histamine receptor 2 (H2) antagonists ranitidine or famotidine inhibits both primary breast tumor development and metastasis, in three distinct mouse tumor models and reduces the numbers of monocytic MDSC. These findings have enormous potential to aid in effective cancer immunotherapy and may have immediate implications for cancer patients. The objective of this investigation is to determine whether treatment with the H2 receptor antagonist ranitidine alters immune suppression, through modulation of immune cell populations. The investigators will examine peripheral blood monocyte, neutrophil and NK cell numbers, subsets and activation status from healthy volunteers treated for 6 weeks with daily oral ranitidine. Ranitidine is widely available and used over the counter in Canada. These drugs are widely recognized as safe, well tolerated and have very few side effects. It has been suggested that among the general population, over 10% of those over the age of 65 take such medications on a regular basis for relief against gastrointestinal discomfort. The outcome of pre-clinical studies in mice warrant further investigation into transferability to humans. If the outcome of the current proposal proves to be viable, then these drugs could provide a safe method to reduce tumor associated immunosuppression with broad implications, both for current cancer patients and for those at high risk of developing cancer. Further to this, the outcome of our proposal may provide a new strategy for improving the effectiveness of T-cell mediated immunotherapy.
OBJECTIVE: Anorexia Nervosa (AN) is a complex disorder of unknown etiology that is characterized by disordered eating behaviors and specific psychopathology. In the course of anorexia around 50% will recover in the first 10 years, 25% will continue to experience symptoms but will be able to function, and 25% will go to develop chronic course, and by definition become severe treatment resistant(Tr). There is little if anything to offer to this population where the range of treatment options is limited to weight restoration interventions. Transcranial magnetic stimulation (rTMS) is a non-invasive intervention, which presents a particular interest in people with severe TrAN, specifically because of its ability to target deeper areas of the brain, such as insula, which has been argued to be a possible trait marker for AN. METHODS: This pilot study will test the efficacy and safety of deep-rTMS delivered with the H-coil in subjects with long standing treatment resistant severe anorexia nervosa (TrAN).
This study will examine the safety and feasibility of using an exoskeleton in subjects who are less than 6 months post spinal cord injury (SCI).
When considered from a provincial perspective, quantification of surgical procedures undertaken by different hospitals and healthcare networks is necessary for informing resource allocation and modelling of healthcare services. The investigators hypothesized that i) non-physiologically complex surgical procedures would account for most (>1/2) of pediatric surgical procedures performed at both pediatric specialist hospitals and the other hospitals performing pediatric surgery, ii) surgical discharges for non-physiologically complex surgical procedures would account for most (>1/2) in-hospital bed nights among pediatric surgical admissions at both pediatric specialist hospitals and the other hospitals performing pediatric surgery, and iii) the relative distributions of non-physiologically complex surgical procedures, but not physiologically complex procedures, would be at least moderately similar between pediatric specialist hospitals and the other hospitals performing pediatric surgery. To test these 3 hypotheses, the specific objectives of this study were to estimate i) the proportion (primary outcome) of non-physiologically complex pediatric surgical procedures, and ii) the similarity and diversity (secondary outcomes) of non-physiologically and physiologically complex surgical procedures between the pediatric specialist hospitals and the other hospitals performing pediatric surgery in Ontario, Canada.
Recent research has suggested that mindfulness-based interventions (MBI) for psychosis may be effective in reducing the negative symptoms of schizophrenia (e.g., social withdrawal, lack of motivation) and the distress associated with psychotic symptoms (e.g., hearing voices) and could lead to improvements in functioning and quality of life. MBI research to date has primarily focused on studies of patients with chronic psychotic illness, yet relatively little is known about the use of MBIs for youth recovering from their first episode of psychosis. Results from recently published pilot studies appear promising in terms of the feasibility, acceptability, and potential clinical utility (e.g., improved psychological symptoms) of MBIs for the early psychosis population (Ashcroft et al., 2012; van der Valk et al., 2013; Khoury et al., 2015). The current project team has completed a pilot study at the Prevention and Early Intervention Program for Psychoses (PEPP) at London Health Sciences Centre (LHSC), wherein the "Mindfulness Ambassador Council" (MAC), a 12-week facilitated group intervention promoting mindfulness skills and the development of emotional and social competencies, was shown to be an effective, feasible, and acceptable means of treating youth in the early stages of psychotic illnesses. In follow up to the initial pilot study, the purpose of this study is to perform a multi-site Randomized Control Trial to determine the effectiveness of the MAC group intervention on reducing psychotic disorder symptomatology for transitional aged youth experiencing early psychosis. The main hypothesis, based on previous findings on the use of MBIs in psychotic disorders, including results from our initial pilot study at PEPP, is that people with early psychosis who participate in the MAC group intervention will experience improvement in mindfulness skills and affective symptoms compared to those receiving treatment as usual (TAU). Furthermore, we expect that people experiencing early psychosis who participate in MAC will have an improvement in their negative symptoms, quality of life, recovery (self-esteem, perceived recovery), perceived coping, assertiveness, social functioning, and cognitive skills, and a reduction in healthcare service utilization (e.g., emergency room visits, inpatient admissions/length of hospitalization).
The investigators are interested in finding accessible interventions for youth and young adults that help promote long-term positive mental health functioning. They will be investigating the effects of Team Unbreakable, a 13-week, twice weekly running group, on mental health symptoms, memory, and attention. This intervention will hopefully improve mental health functioning in youth aged 17-25 that are at high risk of developing mental health disorders. Sessions will consist of 30 minutes of running under the supervision of group leaders and coaches. The group will steadily increase the distance and time spent running versus walking, with the goal of having everyone run a 5 km race together at the end of 13 weeks. Once a week, youth will be provided with education on a variety of topics related to health and running. Youth will complete measures before, during, and after the program to assess outcomes.
