The primary objective of this pilot randomized controlled trial (RCT) is to test the feasibility (recruitment rate, retention rate, participant burden, adherence, technical issues, safety) and usability (system usability scale, SUS) of Omnidirectional treadmill Virtual Reality training (omni-VR) among chronic stroke survivors. Our secondary objective is to (1) estimate the extent to which cognition, brain activation during a dual task activity, walking ability, and dynamic balance change after 3 months of training among intervention participants (omni-VR) and traditional exercise controls, and (2) estimate the extent to which health-related quality of life and motivation co-evolve with our secondary outcomes. Researchers will compare the intervention group and control group to evaluate the impact of omni-VR on cognition and physical function among stroke survivors. Participants will: * undergo a 45-minute training session 3 times per week for 12 weeks * intervention group: omni-VR * control group: traditional exercise program (strengthening and walking activities)

Patients undergoing thyroid biopsy under local anesthetic will be asked to fill out a questionnaire that evaluates their anxiety level before and after their procedure. Patients will be randomly assigned to either use an anxiety reducing tool (stress balls in each hand) to take their mind off the procedure or will not receive an anxiety reducing tool.

This is a pilot study that will evaluate disease status in children that have been newly diagnosed high-grade glioma with TRK fusion. The evaluation will occur after 2 cycles of the medication (Larotrectinib) have been given. The study will also evaluate the safety of larotrectinib when given with chemotherapy in your children; as well as the safety larotrectinib when given post-focal radiation therapy.

The goal of this clinical trial is to evaluate the safety and tolerability of felzartamab plus standard of care in participants with refractory Lupus Nephritis (LN).

This is a two-part study that will evaluate the safety and efficacy of APG777 in participants with moderate-to-severe Atopic Dermatitis (AD). Part A (Proof-of-concept) and Part B (Dose-regimen Finding) will evaluate the safety and efficacy of various induction and maintenance dose regimens of APG777 compared to placebo. The study duration for any individual participant will be up to 106 weeks which includes: screening, induction, maintenance, and post-treatment follow-up periods. Participants randomized in Part A are not permitted to participate in Part B.

The purpose of this study is to evaluate the safety and efficacy of zipalertinib in combination with standard first-line platinum-based chemotherapy compared to chemotherapy alone, in patients with locally advanced or metastatic NSCLC with EGFR ex20ins mutations.

Obsessive-compulsive disorder (OCD) is a disabling psychiatric illness that is characterized by distressing obsessional thoughts and time-consuming compulsive rituals. Exposure and Response Prevention (ERP) is a first-line psychological treatment of choice that requires patients to face their fears by being exposed to feared stimuli. This treatment has been shown to reduce symptoms in a significant proportion of patients. However, it is considered a difficult treatment and only a minority reach remission. Residual symptoms typically remain, or reappear after treatment, which is a risk for relapse. Inference-based Cognitive Behavioral Therapy (I-CBT) is a promising evidence-based treatment developed to overcome these limitations. I-CBT has already been found to be as effective as ERP and significantly more acceptable and easier to adhere to. There is also evidence that I-CBT is more effective for subgroups of patients. Consequently, the current research project is focused on improving treatments outcomes for those provide those who have previously unable to reach remission of their symptoms with ERP. Following an initial treatment with ERP, those that have been unable to reach remission, will be randomized to either I-CBT or more ERP. It is expected that I-CBT will be significantly more effective than providing patients with more of the same. In addition, the study aims to predict treatment outcome in order to be able to tell in advance which patients do not respond to ERP. The project is designed to maximize beneficial health outcomes with a stepped-care approach to treatment, but also to work towards a more personalized choice by being able to match patients in advance with the treatment that works best for them

Background: Over 60% of Canadians are overweight or obese and more than half have a history of a mental illness. The COVID-19 pandemic has made it difficult for people living with obesity to manage their weight even after undergoing bariatric surgery. These difficulties in combination with the stress of the pandemic can cause significant declines in mental health and well-being. Psychotherapy ("talk therapy") has been shown to be effective in helping to reduce mental health and disordered eating symptoms in patients managing obesity; however, there is limited data in the context of COVID-19. Objective: This study will examine whether providing a convenient and accessible telephone-based psychotherapy during and potentially after the COVID-19 pandemic will lead to better mental health and disordered eating-related outcomes in patients managing obesity after weight loss surgery. Hypothesis: Relative to the control group, those receiving psychotherapy will have lower mental health distress and eating disorder symptoms. Methods: Participants recruited from 4 weight loss surgery programs across Ontario will be randomly assigned to one of two groups: 1) Control (7 weekly non-structured check-in emails and access to online COVID-19 related mental health resources) or 2) Tele-CBT (a 7-session telephone-based cognitive behavioural therapy \[a type of "talk therapy"\] intervention focused on developing coping skills and specifically designed for weight loss surgery patients). Participants will complete measures of mental health distress, eating behaviours and a psychological distress scale prior to and immediately following the intervention. Implications: If Tele-CBT is found to improve post-pandemic mental health distress and eating behaviours, it could be routinely offered to patients with other chronic medical conditions as a resource to help manage psychological distress and mental health concerns emerging during and after the COVID-19 pandemic.

Traditional randomized clinical trials (RCTs) have provided extremely valuable information on medical therapies and procedures that have changed the way heart diseases are treated. However, despite these contributions, traditional RCTs are costly, the findings may not be applicable to patients unlike those in the study, and the use of trial findings may be infrequent. These limitations may be addressed by incorporating 'big data' in RCTs, which is the emerging field using electronic information that is routinely collected in various large administrative health databases. The Community Heart Outcomes Improvement and Cholesterol Education Study (CHOICES) will test the potential of using 'big data' in a 'real-world' clinical trial to measure outcomes using routinely collected health information. CHOICES aims to increase the use of cholesterol-lowering statin drugs to prevent heart attack and stroke in high-risk health regions across Ontario using a 'toolbox' of interventions. The 'toolbox' of interventions are informational strategies targeted for both patients and family physicians to help improve cholesterol management and contribute to shared decision making for heart healthy goals.

Choline is an important building block of phospholipids in cell membranes. Certain cancers and medical conditions are known to demonstrate increased absorption and incorporation of choline into their cell membranes. 18-F-fluorocholine (F-choline) and 11-C-choline (C-choline) are diagnostic positron emission tomography (PET) radiotracers that can be used to image, in vivo, the metabolism of choline. Both tracers have been extensively studied in prostate cancer and C-choline has obtained US FDA approval for the investigation of recurrent prostate cancer. F-choline is currently not approved for clinical use by the FDA or Health Canada, but it offers many advantages over C-choline due to its better physical characteristics (mainly due to its positron range, shorter and longer half-life). In recent years, reports have started to emerge on broader potential applications of choline PET imaging, particularly for imaging parathyroid adenomas, certain cervical cancers and certain liver cancers. The main objective is to discover and explore potential new and emerging indications in which F-choline could play a role and provide clinically relevant information. Secondary objectives are 1) To assess the safety of F-choline PET imaging using F-choline produced at the CRCHUM; 2) assess changes in patient/disease management following F-choline PET imaging. Researchers hypothesize that F-choline will provide useful and incremental clinical information in a variety of conditions, and outperform the "standard" workup in numerous conditions. F-Choline PET exams will be performed on hybrid PET/CT scanners according to standard procedures. These examinations could be repeated at the discretion of the treating physician (up to a maximum of 4 exams per year) if the treating physician and the research team deem this could provide additional clinically useful information (for example, by helping to assess response to newly started therapy). The results will be provided to the attending physician and any new knowledge could lead to a change in treatment or an investigation of the condition that prompted enrollment in the study.
