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.
The study will examine the effectiveness of a decellularized dermal matrix (i.e., DermGEN™) in improving wound healing, quality of life and associated costs of treatment of DFUs in First Nations people living in the Northwestern Ontario Communities. First Nations people with active diabetic foot (DFU) ulcer attending a wound care clinic located at the Rainy River district office. An interventional, two-arm, randomized, prospective study of (1) standard of care (control) vs. (2) DermGEN™ - a decellularized dermal matrix (treatment) will be used in the treatment and management of DFU. Patients will be randomized to each arm (n=60 per arm) based on power calculations using data from our Pilot study.
Currently, Family Based Treatment (FBT) is the leading evidence-based, manualized treatment for adolescents with anorexia nervosa (AN). FBT emphasizes parental involvement in addressing disordered eating by supporting the child in eating and refeeding to achieve a healthy body weight and independent eating. Based on multiple RCTs, 50% of AN patients who receive FBT recover, and those who do not are more likely to develop a chronic illness. Research demonstrates that weight gain of less than 2.3kg (4.8 pounds) by week 4 of FBT predicts that 75% of adolescents with AN will not achieve weight restoration by the end of treatment. FBT works in part by reducing the avoidance of food and increasing the exposure to food triggers, like the treatment of anxiety disorders and obsessive-compulsive disorder (OCD). Thus, researchers postulate that anxiety may be a negative predictor of FBT treatment outcome in the early phase of FBT. In addition, elevated baseline anxiety has been shown to be associated with poorer outcomes at end of treatment and may also impact the likelihood of early response. To improve clinical response, we need to develop viable biological treatment targets (i.e., brain areas implicated in anxiety) that could be combined with FBT. Such targets can be defined by 1) initially targeting brain areas that mediate symptoms hindering treatment response (i.e., anxiety), and 2) looking at changes in brain chemistry and function. Thus, repetitive transcranial magnetic stimulation (rTMS) could be an alternative and promising treatment approach for adolescents with AN who do not respond to Phase 1 of FBT. Using rTMS, we can target the brain areas implicated in anxiety in people with anorexia and modulate that activity to reduce symptoms, and thus, facilitate response to FBT. Several studies have shown the rTMS to the right dorsolateral prefrontal cortex (DLPFC) is effective in reducing anxiety across a range of neuropsychiatric disorders. Therefore, it is possible that stimulating the right DLPFC could facilitate treatment efficacy of FBT in youth with AN. Additional explorations of the connections between, and neurochemistry of, the right DLPFC and those mediating emotion in the brain (e.g., amygdala) could aid in our understanding of the networks impeding effective treatment responses and allow for more tailored, precision targeting with TMS.
Sleeve gastrectomy (SG) has become the most commonly performed weight loss surgery, accounting for 60% of all bariatric operations worldwide. While technically easier with less side-effects and nutritional risks than other operations, SG is also associated with a higher risk of failure (20 to 40%). In such case, the most effective option consists in adding an intestinal bypass called the Biliopancreatic Diversion with Duodenal Switch (BPD-DS). This surgery is, however, technically challenging and yields a significant risk of complications, nutritional deficiencies or gastro-intestinal side-effects. Recently, a simplified version of the Standard DS, called Single-Anastomosis Duodenoileal Switch (SADI-S) was endorsed by surgical societies as one of the approved bariatric procedures. There is currently no prospective or randomized data to support the effectiveness of this new procedure, especially as a revisional approach. The Overall Objective of this randomized controlled trial project is to establish the clinical benefits of the SADI-S as a revisional surgery after SG, while also considering critical issues related to sex and gender. The investigator Overall Hypothesis is that the SADI-S represents a relevant revisional option for weight loss and metabolic recovery in women and men suffering from severe obesity who had a previous SG. The investigator propose to address the following research question. Research Question: What are the clinical effects of SADI-S compared to standard DS when used as a revisional procedure after SG, in patients with obesity? Participants who need revisional surgery after SG will be enrolled in a prospective, randomized, double-blind (patient-evaluator), non-inferiority trial comparing SADI-S vs DS. The primary outcome will be 12-month excess weight loss. Secondary outcomes will be perioperative complications, risk of malnutrition, quality of life and gastrointestinal side effects. The investigator hypothesize that SADI-S offers similar weight loss compared to standard DS, but a lower risk of complications and nutritional deficiencies. With the increase in the number of bariatric operations performed worldwide and the recent endorsement of the SADI-S as a regular procedure, reliable clinical data are urgently needed. The present proposal will directly address this knowledge gap.
Obesity can be a major driver for the development of chronic kidney disease (CKD), which is a leading cause of death and significant loss in quality of life. A growing body of evidence has shown bariatric (metabolic) surgery as a novel approach to reduce the progression of CKD and reduce morbidity with sustained weight loss. This pilot trial will inform the design and execution of a large RCT that could determine the efficacy of bariatric surgery in the treatment of patients with CKD in the context of obesity. Ultimately, the results have the potential to influence guidelines that may deem bariatric surgery as a viable treatment option for CKD and reduce the morbidity from this chronic condition and inform clinical practice.
The aim of this study is to evaluate the impact of the FreeO2 system on the quality of the oxygen therapy in confirmed or suspected SARS-CoV-2 patients in the emergency department.
Use of continuous positive airway pressure (CPAP) in preterm neonates has traditionally been limited to between 5-8 cmH2O. In recent years, use of CPAP pressures ≥9 cmH2O is becoming more common in neonates with evolving chronic lung disease, in lieu of other non-invasive modes or invasive mechanical ventilation. A particular knowledge gap in the current literature is the choice of the level of pressure level when using High CPAP as a post-extubation support mode. In this study, we will comparatively evaluate the short-term impact of two different high CPAP pressures when used as a post-extubation support mode in preterm neonates.
Diet is a determinant of gut microbial diversity and composition and is recognized as a potential environmental trigger for IBD; for example, high-fat diets are associated with increased risk of CD in pre-clinical models, with effects mediated through dysbiosis and altered gut permeability. Diet is also a potential non-pharmacological therapy for weight loss and for reducing the occurrence of disease flares and the reliance on dose escalation of biologic agents. Indeed, there is accumulating evidence for the role of diet in the treatment of CD, and diet-induced improvement of microbial dysbiosis is associated with induction of remission in pediatric patients with active CD. Intermittent Fasting (IF) is a dietary intervention that involves periodic intervals of no or very limited energy intake. We want to determine the efficacy and feasibility of a 12-week IF(Intermittent Fasting) intervention to induce weight loss (by 1 BMI unit reduction), decrease biomarker inflammation and increase microbial functional diversity compared to standard medical management (SM) in a pilot study of individuals with overweight or obesity and CD in clinical remission with elevated biomarkers of inflammation, indicated by fecal calprotectin (FCP) > 250 µg/g or C-reactive protein (CRP) > 5 mg/L).
Human Milk alone is unable to meet the high nutritional requirements of preterm infants. The American Academy of Pediatrics recommends fortification of human milk as a standard practice in all very low birth weight (VLBW) infants. Multi-nutrient human milk fortifiers (HMFs) are designed to meet the macro and micro-nutrient needs of VLBW infants. HMFs differ by the origin of milk and by nutrient composition. Traditionally, bovine milk has been the main source of multi-nutrient HMFs.
In 2019, the Enhanced Recovery After Surgery (ERAS) Society published recommendations for perioperative care in cardiac surgery. ERAS recommendations included 22 perioperative interventions that may be part of any cardiac Enhanced Recovery Program (ERP). Since that publication, additional perioperative interventions were reported and may be added to a cardiac ERP. Studies on cardiac ERPs report variable benefits on postoperative recovery including lower pain scores, lower opioid consumption and related side effects, shorter intensive care unit and hospital discharge times. At the "Centre Hospitalier de l'Université de Montréal" (CHUM), although most care takers are aware of ERAS recommendations for cardiac surgery patients, adherence to these recommendations is heterogeneous and a cardiac ERP was never implemented.
HIV is the leading cause of death for adolescents and young people (AYP) in sub-SaharanAfrica (SSA). Uganda hosts 1.4 million refugees/displaced persons and the Bidi Bidi refugee camp in Northern Uganda is the second-largest refugee settlement in the world and the largest in Africa. There are reports of high sexual and gender-based violence (SGBV) among refugees during the journey from South Sudan to Uganda and in the refugee settlements, yet low rates of HIV testing and access to HIV prevention services, particularly tailored for gender, age, and the refugee settlement context. This study aims to develop, implement and evaluate an oral HIV-self testing (HIVST) intervention with displaced/refugee AYP aged16- 24 in Bidi Bidi. HIVST is acceptable and properly used with AYP in other SSA regions, yet there are knowledge gaps regarding the best way to link HIVST to HIV care. This study aims to explore how user-developed educational comic books can improve linkage to care with HIVST. This trial focuses on implementing a randomized trial with displaced/refugee AYP aged 16-24 living in Bidi Bidi (Arm1: HIVST; Arm 2: HIVST + comic book; Arm 3: comic book; Arm 4: standard of care). The study will assess changes in HIV testing practices, HIV status knowledge, and linkage to HIV prevention and care between the 4 arms.
