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 opioid crisis is a growing problem around the world, with prescription opioids being a major contributor to this crisis. They can be prescribed in different chronic and acute settings, such as surgery. This is therefore an event which may mark a first exposure to opioids in many opioid-naive patients and be associated with subsequent long-term use. This long-term persistent opioid consumption (POC) after surgery may be due, among other things, to chronic postsurgical pain (CPSP). Many risk factors have been identified in the development of chronic pain. Some are related to the surgery while others are related to patient characteristics. Of these, preoperative opioid use, pre-existing pain, and psychological history are major factors that increase the risk of POC or CPSP. The population having undergone major abdominal surgery remains poorly represented in studies of postoperative POC. It can be reasonable to think that these patients may have a similar high risk of CPSP and POC as other surgical patients. The potential harmful effects of POC and CPSP may limit the recovery of these patients and impair their quality of life (QoL). The risk factors for CPSP are important to consider when considering POC. While psychological factors related to pain have been shown to be associated with postoperative pain and analgesic use, the association between unrelieved postoperative pain and POC may have been underestimated. Regional anesthesia is frequently used in major abdominal surgery to reduce the risk of acute and chronic postoperative pain. However, data regarding CPSP specifically after major abdominal surgery are lacking, and the role of neuraxial analgesia on its prevention and on postoperative opioid use is unclear. Since little is known about the prevalence of POC after major abdominal surgery and its determinants, the investigators propose to conduct a major abdominal surgery cohort study by examining POC and CPSP using information reported by patients.
This is a randomized, controlled pilot study to evaluate the feasibility and acceptability of a single 2-hour culinary medicine intervention for bone health among individuals with age-associated low bone mass.
Food forms an integral part of diabetes management. As children mature into young adults, they must learn to adopt lifestyle behaviours critical for optimal diabetes care. The development of food preparation and cooking skills at a young age may help to facilitate healthy food choices in children and provide a solid foundation for young adulthood. Food skills workshops are effective interventions that have been shown to improve food literacy and healthy eating in the general pediatric population. However, food skills programs have not been adequately evaluated in children with type 1 diabetes. Further, virtual programs are not well assessed, which can increase the accessibility of food education during the pandemic and in the future.
The purpose of this study is to evaluate the efficacy and safety of guselkumab in participants with Crohn's disease.
A clinical trial investigating the safety and effectiveness of Smith and Nephew's FDA-approved Porous Total Knee System, which is used to replace worn away and diseased knee joints. The aim of this study is to show that most patients who receive the Porous Total Knee System have reduced pain, greater mobility and a long-lasting implant post-surgery.
This is a prospective, single-blind, controlled trial. There are two arms and 20 patients with acute or chronic wounds with clinical suspicion of biofilm (CSB+/CSB-) are allocated in each arm. The primary objective is to evaluate the diagnostic accuracy of MolecuLight fluorescence in identifying biofilm as validated by gold standard SEM imaging.
This is an observational, proof-of-concept, feasibility study where 50 preterm infants with gestational age < 32+0 weeks will be recruited from the neonatal intensive care unit (NICU) at the Montreal Children's Hospital. The study's primary objective is to describe the relationship between respiratory acoustics and airflow and determine the reliability of a novel respiratory acoustic sensor at detecting breathing sounds in preterm infants. The study's secondary objectives are: 1. To compare transthoracic impedance, respiratory inductive plethysmography and an inertial measurement unit for the detection of respiratory efforts in preterm infants. 2. To evaluate the feasibility and accuracy of a novel, non-invasive method for continuously detecting and differentiating cardiorespiratory events in preterm infants on CPAP by integrating measurements of respiratory effort with respiratory acoustic monitoring.
Coronavirus-2019 (COVID-19) is a viral disease leading to respiratory dysfunction, but it may also affect the brain and result in the development of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). This may be the result of the COVID-19 virus infecting regions of the brain responsible for respiratory control. The symptoms of COVID-19 long haulers and ME/CFS may be lessened via an 8-week inspiratory muscle training protocol which is a simple and easy training protocol which can be done at a patient's home. Thus, this project will investigate changes in the breathing and cardiovascular responses to stimuli in three groups of participants: 1) healthy control individuals; 2) patients diagnosed with ME/CFS (mild to moderate symptoms); and 3) individuals with previous COVID-19 infection with long-haul symptoms lasting for at least 3 months. Participants will 1) breathe hypoxic gas (10% O2) for 5 minutes; 2) breath hypercapnic gas (5% CO2) for 5 minutes; 3) breathe at a rate of 6 breaths per minute for a total of 8 breaths (paced deep breathing); and 4) complete 10 minutes upright tilt (70 degrees head up on a tilt-table). Patients will also complete 2 questionnaires concerning their symptoms and a 15 minute cognitive function test on a lab laptop. This will allow for the assessment of the brain's control over blood pressure and breathing. Participants will also complete a 6-minute walking exercise test at their own speed as a measure of their aerobic fitness. We hypothesize that COVID-19 survivors will have a worse cardiovascular and autonomic response and lower fitness, similar to ME/CFS patients, compared to healthy participants.Further, this will be improved after 8-weeks of inspiratory muscle training. These results may help clinicians recognize ME/CFS symptoms in patients recovering from COVID-19.
The objective of this study is to evaluate the effectiveness of virtual reality (360° video) compared to a social story for reducing pre-visit dental anxiety for children with autism spectrum disorder (ASD) improve the dental visit experience for children, their families, and clinicians. The secondary objective is to perform a cost comparison analysis of the 360° video product as compared to a social story for Holland Bloorview's dental clinic.
The objectives of the study are to evaluate trunk task-oriented training combined with function electrical stimulation (FES/T-TOT) efficacy on sitting balance and functional independence, and to understand the mechanisms of neuroplasticity that would improve functional independence following FES/T-TOT in individuals with spinal cord injury.
