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.
Traditional training of surgical technical skills relies on mentorship from experienced surgeons, who continuously evaluate and change trainee performance to prevent errors and potential patient harm by providing verbal instructions. These educators may also pause the procedure, explaining the risks associated with the trainee's actions, and may personally demonstrate proper techniques to the students. Studies examining pausing while providing medical care outline that these approaches allow for learning. An artificial intelligent (AI) tutoring system, the Intelligent Continuous Expertise Monitoring System (ICEMS), improves learning in a surgical simulated operation by providing trainees with verbal instructions upon error identification. However, the effect of including a pause during this AI teaching has not been studied. Therefore, the ICEMS post-error identification methodology has been altered to include a pause with the intelligent tutor voice instruction. The aim of this study is to determine the effect of pausing on surgical skill acquisition and transfer among pre-medical and medical students. This will be done by comparing their performance in repeated simulated tumour resection tasks.
This study is being done to answer the following question: Is the strategy to give higher doses of radiotherapy treatment over a shorter period of time using special equipment and fewer treatments (also known as Stereotactic Body Radiation Therapy or SBRT) as effective as usual external radiation therapy given with a brachytherapy boost (which involves radiation sources inserted directly into the prostate)?
Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) are the first and second most commonly reported sexually transmitted infections (STI) in Canada, respectively, and rates are increasing. While CT and NG can cause a variety of non-specific symptoms, an estimated 77% of CT and 45% of NG cases are asymptomatic. Consequently, many individuals remain undiagnosed, or have delayed diagnosis and consequently miss effective and well-tolerated therapies and may transmit the infection(s) to sexual partners. Untreated CT infection may result in serious sequelae. Also, CT and NG infection are associated with increased risk of acquiring HIV and some cancers. Access to STI testing and treatment are two of the core pillars in the Pan-Canadian Sexually Transmitted and Blood Borne Infections (STBBI) Framework for Action. Currently many Canadians lack a primary care physician and many STI specific clinics are centered in urban areas, further challenging access in rural communities. Increasing access to these core pillars is paramount to reduce the health impact of STBBIs in Canada by 2030. The purpose of this study is to implement and evaluate a novel pilot project including pharmacy-based CT and NG management (including specimen self-collection [pharyngeal, anorectal and/or vaginal swabs, and/or urine sample], assessment, treatment, and linkage to care) by community pharmacists in Nova Scotia.
The goal of this trial is to compare the effect of a web-based educational video about pneumococcal vaccines and a reminder email to get vaccinated (intervention) with a reminder email alone (comparator) in adults aged 65 or older living in any Canadian province who reported not having received a pneumococcal vaccine. The main questions this trial aims to answer are: 1. does the educational intervention improve pneumococcal vaccine uptake, 2. does the educational intervention improve willingness to be vaccinated, 3. does the educational intervention improve knowledge of pneumococcal vaccination, 4. and does the educational intervention improve attitudes towards pneumococcal vaccines/vaccination? Eligible participants who provide electronic consent will: 1. fill out a web-based baseline survey, 2. receive access to the educational video (if assigned to the intervention group), 3. receive an email reminder to be vaccinated (both groups), 4. and fill in a web-based follow-up survey.
Loss of skeletal muscle mass (atrophy) and strength in the lower limb are consequences of elective knee surgery as result of prolonged disuse from limb immobilization and impaired mobility, as well as pathophysiological trauma. The highest rates of skeletal muscle mass and strength loss occur during the 2-week post-surgery period, considered the early phase of outpatient recovery. Alternative to resistance exercise and pharmacology, nutritional intervention represents one strategy to combat skeletal muscle disuse atrophy. Essential amino acids (EAA) and omega-3 fatty acids are known to independently potentiate rates of skeletal muscle protein synthesis and attenuate skeletal muscle atrophy in humans. However, the combined actions these nutritional strategies on skeletal muscle have not been explored in a pathophysiological context, such as surgery. With the ultimate goal to test the efficacy of the combined nutritional strategy to attenuate skeletal muscle disuse atrophy in the future, the aim of this present pilot study is to explore the feasibility of recruitment and retention of anterior cruciate ligament reconstruction (ACLR) outpatients from a single centre across 18 months for a 6-week nutritional intervention. Participants will consume either an intervention of omega-3 fatty acids and EAAs, or a placebo control of safflower oil and non-essential amino acids (NEAA), for 4 weeks before and 2 weeks after elective ACLR surgery. Furthermore, this pilot will characterize secondary outcomes of skeletal muscle mass, strength, and power, and integrated rates of muscle protein synthesis, as well as report participant adherence to protocols and incidence of adverse events.
Crohn's disease (CD) is a long-lasting condition causing inflammation that can affect any part of the gut. The purpose of this study is to evaluate the efficacy and safety of TAK-279 versus placebo in participants with moderately to severely active Crohn's disease (CD). The main aim of this study is to learn if the 3 different doses of TAK-279 reduce bowel inflammation and ulcers in the bowel compared to the placebo after 12 weeks of treatment. Another aim is to compare any medical problems that participants have when they take TAK-279 or placebo and how well the participants tolerate any problems. An endoscopy will be used to check the bowel for inflammation. The participants will be treated with TAK-279 for 52 weeks (1 year). During the study, participants will visit their study clinic 15 times.t
The purpose of this study is to evaluate the efficacy and safety of alnuctamab compared to standard of care regimens in participants with relapsed or refractory multiple myeloma (RRMM).
Transcranial Ultrasound Stimulation (TUS) is an emerging non-invasive brain stimulation technique capable of targeting both superficial and deep brain areas with high spatial resolution, down to a few cubic millimeters. In this study, the investigators aim to use TUS to non-invasively modulate the globus pallidus internus (GPi) in patients with Parkinson's disease (PD) and dystonia. These patients have previously been implanted with deep brain stimulation (DBS) leads. The investigators plan to simultaneously record local field potentials (LFPs) from the DBS leads using the Percept PC device (Medtronic Inc.) while the DBS is turned off. The study's goal is to investigate the mechanism of action of TUS and its neuromodulatory effects on LFPs recorded from the GPi. This will enable us to compare the effects of TUS with those of DBS.

This study aim to evaluate whether a dose of 5 mg of lemborexant, as compared to a placebo, may improve daytime recovery sleep, without producing lingering sleepiness during wakefulness, using a 3-day simulated night shift protocol in the lab under constant monitoring.
