The purpose of this study to optimize Selective Laser Trabeculoplasty (SLT) application when used in the management of open angle glaucoma (OAG)

Psilocybin, the chemical component of "magic mushrooms", has been administered with psychotherapy in several randomized clinical trials (RCTs) showing large and sustained antidepressant effects. There is interest to see if similar effects may be provided in those with obsessive compulsive disorder (OCD). The purpose of this study is to evaluate the safety, feasibility, and clinical effects of psilocybin administration in those with OCD. Ten participants with treatment-resistant OCD will receive two doses of 25mg of psilocybin under supportive conditions, two weeks apart. The investigators hypothesize that two sessions of psilocybin 25mg administered under supportive conditions to participants with treatment-resistant OCD will lead to significant reductions in OCD symptoms.

Chronic spinal pain (CSP) is one of the most common chronic pain conditions globally. Steroid joint injections (SJI) are a routine treatment option for patients with CLBP that is recalcitrant to other treatments. However, SJI has been shown to have limited long-term efficacy with patients often requiring another injection within months to adequately control pain. One option to prolong the analgesic effects of SJI is to use a type of noninvasive brain stimulation called repetitive transcranial magnetic stimulation (rTMS). Previous studies have shown rTMS may be capable of providing long-term pain relief in patients with chronic back pain. However, the literature on rTMS in patients with CSP is limited and no study has explored rTMS in patients receiving recurrent SJI for pain control. In this pilot randomized controlled trial study, we'll be investigating if combining rTMS with SJI in CSP individuals will enhance or prolong the analgesic effects of SJI alone. The investigators hypothesize that a combined rTMS and SJI intervention will be feasible, tolerable, and safe and will have larger and longer-lasting effects on CSP than a sham rTMS and SJI intervention.

BR36 will evaluate the potential clinical benefit of tailoring immunotherapy treatment based on ctDNA molecular response in non-small cell lung cancer.

Heart transplantation is the long-term treatment for children and adults with advanced heart failure. Post-transplant outcomes have improved over time, such that 50% of pediatric heart transplant recipients (HTR) remain alive with a need for re-transplantation 17-years following the initial transplant. With improved short- and medium-term outcomes, focus has shifted towards optimizing long-term survival and reducing transplant-associated morbidities. This includes strategies aimed at optimizing cardiorespiratory fitness and physical activity levels. Pediatric and adult HTRs have reduced exercise capacity compared with the general population. Previous groups have shown gradual improvements in heart rate response to exercise and exercise capacity in pediatric HTRs. However, after an initial improvement, exercise capacity appears to plateau, or even decline in pediatric HTRs, and remains sub-optimal compared with the general population. Most exercise interventions in HTRs to date have focused on moderate-intensity continuous exercise (MICE), with some resistance components incorporated. More recently, high-intensity interval training (HIIT), consisting of short, intense bursts of exercise with rest periods, has been explored in the adult HTR population, with findings to date suggesting that it may yield greater improvements in cardiorespiratory fitness compared with MICE. Exercise interventions, particularly HIIT interventions, have consistently shown clinically important improvements in exercise capacity in adult HTRs that are linked with improved long-term post-transplant outcomes and well-being. Unfortunately, trials of exercise interventions in pediatric HTRs remain lacking. This study team is proposing an assessment of the feasibility of a home-based HIIT exercise program using a novel telemedicine-enable video game linked customizable cycle ergometer (MedBIKE™).

Brain metastasis (BrM) develops in approximately 40% of cancer patients. Stereotactic radiosurgery (SRS) is a form of radiotherapy that delivers high-dose per fraction to individual lesions that is commonly used to treat BrM. Radionecrosis (RN) is an adverse event that occurs in approximately 10 - 25% of patients 6 - 24 months after treatment with SRS. Tumour progression may also occur due to local failure of treatment. Radionecrosis and tumour progression share very similar clinical features including vomiting, nausea, and focal neurologic findings. Radionecrosis and tumour progression also share overlapping imaging characteristics. Due to their similarities, physicians need to perform a surgical resection to diagnose the complication. By using a hybrid FLT-PET/MRI scan, the investigators propose that this combination scan will provide robust data with which to differentiate between radionecrosis and tumour progression without the need for surgery. The investigators plan to conduct a single center feasibility study to investigate the potential in differentiating between SRS and tumour progression in patients, including those who may have previously undergone SRS for BrM, who are suspected to have either RN or tumour progression using hybrid FLT-PET/MRI imaging.

The purpose is to determine if patients with idiopathic pulmonary fibrosis (IPF) taking nintedanib will have improved exercise endurance, breathlessness and quality of life if breathing 60% oxygen compared to standard of care during an 8 week exercise training program.

Sodium (Na+) hemostasis is abnormal in CKD patients, and this element can be deposited in the skin, muscle, and skeleton - to cope with long term sodium loading. It is known that sodium stored in this non-osmotically active way, is profoundly inflammatory. Furthermore, inflammation has been associated with several uremic symptoms. The investigators will use novel Na+ MRI imaging to examine the Na+ deposition in the skin, muscle, and skeleton of five groups:1) chronic in-center hemodialysis patients, 2) chronic peritoneal dialysis patients, 3) adult and paediatric patients with CKD stage 1-5 and 4) heart failure patients with and without renal dysfunction 5) sex and age-matched healthy adult and paediatric controls. Additionally, they will investigate the association between sodium deposition in these tissues with uremic symptomatology and biochemical markers of metabolism.

The primary objective of this study is to evaluate the effectiveness (prevention of thromboembolic events) and safety (major bleeding) of adding oral anticoagulation (OAC) to background antiplatelet therapy in patients who develop new-onset post-operative atrial fibrillation (POAF) after isolated coronary artery bypass graft (CABG) surgery. All patients with a qualifying POAF event, who decline randomization, will be offered the option of enrollment in a parallel registry that captures their baseline risk profile and their treatment strategy in terms of anticoagulants or antiplatelets received. These patients will also be asked to fill out a brief decliner survey.

Venous thromboembolism (VTE) can be the earliest sign of cancer. Identifying occult cancers at the time of VTE diagnosis may lead to significant improvement of patients' care. This is also an upmost issue for patients who want to know if an underlying cancer might have triggered the VTE. An individual patient-level data meta-analysis (IPDMA) supports extensive screening strategies for occult cancer especially based on FDG PET/CT, and suggests that the best target population for cancer screening would be patients with unprovoked VTE older than 50 years of age (6.7% in patients aged 50 years or more vs. 1.0% in patients of less than 50 years (OR: 7.1, 95% CI: 3.1 to 16%).
