The aim of this project is to conduct a pilot randomized controlled trial (RCT) to evaluate the feasibility and preliminary effectiveness of a virtual group based self-management program (SMP) in adolescents with JIA across different provinces compared to a wait-list control group receiving only standard of care. Participants in the SMP group will partake in four 60-90 minute group sessions conducted over 8 weeks. The intervention is a multifaceted program that includes JIA disease education, self-management strategies, and peer support. Both the interventional and control group will be asked to complete baseline and post-test measures. Participants in the control group will be offered the SMP after completion of the post-control outcome measures.

The goal of this clinical trial is to test alternative dosing of niraparib in patients with newly diagnosed high-grade, advanced stage ovarian cancer. The main questions it aims to answer are: What is the incidence of hematologic and other adverse events? What is the incidence of dose interruption, dose reduction and discontinuation? What is the length of time of progression-free survival at 24 months?

About 65,000 Canadians develop acute respiratory failure requiring breathing machines (ventilators) to give oxygen to their lungs. Unfortunately, up to 50% of these individuals will not survive their illness. Mechanical ventilation through breathing machines, though potentially lifesaving, may further injure the lungs and the respiratory muscles. In the patients with the most severe and life threatening forms of respiratory failure a breathing machine alone may not be able to provide enough oxygen to the lungs and vital organs. In these critical situations, patients may require an artificial lung machine, which is referred to as extracorporeal membrane oxygenation (ECMO) to temporarily replace the function of the patient's own lung and supply critical oxygen to the body, while protecting the damaged lungs. How to use the breathing machine safely while a patient is on ECMO is still unknown. Using conventional breathing machine settings while on ECMO can lead to large portions of the lungs or airway to remain collapsed, which can contribute to further lung damage. The investigators have recently discovered a way of detecting if patients on a breathing machine suffer from collapsed airways. Knowing if the most severe patients on ECMO have airway collapse is a pivotal question that the investigators plan to answer in our study. The investigators will use our technique to determine how many patients on ECMO have airway closure and determine if this contributes to a longer time on ECMO and a longer time on a breathing machine, and if this impacts a patient's survival in the intensive care unit.

Aim of the EndPaRL study is to compare the efficacy and effectiveness of the two techniques utilizing sharp straight conventional radiofrequency needle with a trident needle for radiofrequency neurotomy of Cervical Medial Branch Nerves (CMBNs), in patients presenting with chronic, moderate-to-severe, neck pain due to cervical zygapophyseal joint osteoarthritis, as diagnosed by positive responses to two consecutive diagnostic blocks with local anesthetic of the CMBN.

This is a Phase 2a, multicenter, randomized, double-blind, placebo-controlled study with an open-label extension to evaluate the efficacy and safety of camoteskimab in adults with moderate to severe AD.

The standard or usual workup for cognitive impairment, including Alzheimer's Disease, may include brain amyloid PET with PET/CT or PET/MR imaging. Amyloid PET is the standard imaging that was requested for you by your referring physician. This imaging can visualize your brain. With the development of new therapies for Alzheimer's disease which require amyloid PET imaging, there will be a significant increase in the number of PET scans needed to provide care to all patients. There are likely not enough PET scanners in Canada to meet this demand. Therefore, we are searching for comparable alternatives. One of the imaging devices that was introduced in the clinic is the Radialis PET imager (or RPI). Health Canada, the regulatory body that oversees the use of devices in Canada, has not approved the sale or use of the Radialis PET imager. Health Canada has allowed the Radialis PET imager to be used in this study. We would like to see whether the images obtained for the brain are comparable to those obtained from a PET/CT or PET/MRI scanner. It is a new type of PET imaging device for patients undergoing a PET scan and has been used in Canada for research. RPI is experimental, meaning that this PET scan is not used routinely in patients' care. In comparison to the standard PET devices, RPI is smaller and mobile, meaning it can be moved around easily for use. Also, it can be installed in imaging centers at a lower cost. These advantages make RPI an interesting alternative to the standard PET. However, the performance of this new imaging device has not been tested in Amyloid PET imaging in particular. As you may know, in a PET scan, we inject a radioactive material (called tracer) which can circulate in your body and visualize specific areas in your body. In amyloid PET we inject an amyloid tracer that goes to the brain and lights up certain regions of the brain. RPI was previously tested for other PET tracers and was shown to be comparable to standard PET devices. Thus, by changing the PET material (to Amyloid), we are pursuing the same aim: comparison of RPI with standard PET devices and see whether it can provide comparable images of the brain.

The study is a prospective, randomized, single-blind controlled superiority trial to evaluate the effect of viewing an informative animated video a day prior to surgery on preoperative anxiety in pediatric patients scheduled for elective otoplasty. The primary outcome will be modified Yale Preoperative Anxiety Scale (mYPAS) score at the time of general anesthesia induction compared between families that were assigned to view the animated video the day before and those that were not. The participants for this study will be children undergoing elective otoplasty at the IWK Health Centre. Those participants randomized to the intervention group will receive a link to a short survey gauging parent anxiety levels. The survey will be followed by a link to an informative animated video which the participants and their families will watch. The control group will be participants assigned not to receive the email link to the informative animated video.

The purpose of this study is to identify digital biomarkers associated with type 2 diabetes mellitus (T2DM) by combining sensor data from a wrist-worn wearable and clinical data. This will be done by recruiting patients with and without diabetes within the cardio-metabolic clinics a the MUHC. Consented patients will be provided with a HOP Technologies (HOP) watch in this project across two observation periods. The Watch-HOP platform facilitates the development of predictive algorithms built with data collected in a clinical setting or at home in a passive (sensors) and active (self-assessments) way. Data from the Watch-Hop will be analyzed using machine learning strategies to determine associations with clinical measures of T2DM.

Consented patients undergoing elective total hip and total knee arthroplasty will be randomized to receive either aspirin alone or aspirin and rivaroxaban for prevention of venous thromboembolism.

The goal of the Phase 3a part of this clinical trial is to determine the optimal dose that will be used in the Phase 3b part of this clinical trial. The goal of the Phase 3b part is to assess the efficacy of SNP-ACTH (1-39) Gel relative to rituximab in patients with primary membranous nephropathy (PMN) at month 24.
