The usual standard of care for patients over 65 diagnosed with glioblastoma ("GBM") or Grade 4 astrocytoma, IDH-mutant is a 3-week course of radiotherapy, with concurrent and adjuvant temozolomide (TMZ). This radiation dose and length of treatment are less than what would be given for younger patients, primarily due to unclear survival benefits from randomized trials. However, survival remains dismal, and may be partially due to the reduced radiation dose. Recent studies investigating this have found that increased radiation dose (to the equivalent of what is normally given over 6 weeks in younger patients) over 3 weeks is well-tolerated and has improved survival rates. Additionally, with the advent of novel technology such as the MR-Linac, adaptive radiotherapy with this regimen using reduced radiation margins is possible. Use of the MR-Linac allows for daily MRI scans to be done prior to treatment, so plans can be adapted to tumour dynamics and anatomical deformations. In this trial, we will examine the outcomes of increased radiation dose, combined with reduced-margin adaptive radiotherapy in this patient population.

Lung transplantation is a complex procedure performed in patients with terminal lung disease. The transplant procedure stresses the patient's heart and lungs, which are already taxed by the underlying disease process. The heart-lung machine is occasionally used to support the patient and ensure adequate oxygen supply to other organs during the operation. It can be used routinely in all patients or selectively in patients who exhibit reduced oxygen supply to the remaining organs. This process, known as cardiopulmonary bypass (CPB), pumps blood out of the body to a heart-lung machine that removes carbon dioxide and returns oxygen-filled blood to the body. Although using the CPB increases the risk of bleeding, infection, and coagulation complications, it should still be considered in high-risk patients to compensate for more severe complications such as kidney failure and stroke caused by a lack of cardiopulmonary support. Extracorporeal membrane oxygenation (ECMO) is a recently developed CPB variation associated with fewer bleeding complications. It has recently replaced the traditional heart-lung machine as the preferred method of cardiopulmonary support during lung transplantation. Since ECMO is associated with fewer complications than standard CPB, many centers have increased their use of ECMO during lung transplantation. Some have even employed it routinely. However, there remains significant debate on how often it should be used. Therefore, the study's main objective is to compare the two approaches in lung transplantation, i.e., routine use versus selective use, and to determine if one approach is preferable to the other.

Each year over 20,000 men are diagnosed with prostate cancer in Canada with the majority undergoing some form of treatment option. Radical prostatectomy and/or radiation therapy are common procedures that are effective in the treatment of prostate cancer. However, they typically incur both short- and long-term side effects (e.g. urinary incontinence, sexual dysfunction, reduced physical function, etc) that can negatively impact one's quality of life. This program of research aims to address the most critical needs of PC survivors: the development and evaluation of interventions to address the quality of life impact of PC. This study will test the Prostate Cancer Patient Empowerment Program (PC-PEP) in 400 men, a comprehensive intervention aimed at educating and teaching the men life skills/habits in order to improve their mental health issues, fitness levels and overall quality of life, and to decrease treatment related side effects. The program also aims to improve the overall health of the participants in the long term.

High burden right ventricular (RV) pacing has been shown to increase cardiovascular mortality, incidence of heart failure (HF), worsen left ventricular (LV) function and accelerate the development of atrial fibrillation (AF). High percentage ventricular pacing and wider paced QRS in the setting of normal baseline LV ejection fractions have consistently been shown to be independent risk factors for pacing-induced cardiomyopathy. Left bundle branch pacing (LBBP) has emerged as a potential alternative pacing mechanism that may avoid LV dyssynchrony and pacing-induced LV dysfunction by mimicking native electrical conduction.

Ischemic stroke represents a major public health issue, leading to significant disabilities and deaths worldwide. When no clear cause for stroke is found following a comprehensive cardiovascular evaluation (no atrial fibrillation, cardiac masses, or atherosclerosis) i.e. cryptogenic stroke, it is recommended to search for a patent foramen ovale (PFO), especially in young patients. It is estimated that cryptogenic stroke accounts for 30% to 40% of ischemic strokes. Transthoracic echocardiography (TTE) with bubble study at rest and during Valsalva maneuver is the reference method for the diagnosis of PFO. The treatment of PFO using a closure device has demonstrated a significant reduction in recurrent stroke events in patients with PFO and cryptogenic stroke. The Valsalva maneuver is currently achieved using self-directed maneuver i.e. patients are instructed to ''bear down'' or ''strain as if attempting to move your bowels.'' These instructions are subjective and depend largely on individuals understanding and effort. A Goal-Directed Valsalva Maneuver using a manometer has been shown to be a more reproducible way to perform the Valsalva achieving more sensitivity in different settings such as hypertrophic cardiomyopathy but its incremental diagnostic value for the detection of PFO has not been yet evaluated. The aim of the present study is to compare the sensibility and specificity of two methods of Valsalva maneuver for the detection of PFO. We hypothesize that Goal-Directed Valsalva Maneuver will significantly increase the detection rate of PFO compared to Self-Directed Valsalva Maneuver.

Hirschsprung's Disease (HD) and anorectal malformations (ARM) are both paediatric diseases of the colon and rectum. Both of these conditions require surgery in order to correct them, frequently needing sections of the bowel to be removed. Some complications of removing parts of the bowel include forming a stricture (a narrowing of the place where the bowel is reattached), and leak from the join. These can be devastating complications, and can significantly impact a patient's quality of life. Indocyanine green (ICG) is a medication that binds to blood vessels and can be visualized using special cameras in the operating room. Once it binds, it "lights up" green on this equipment. This lends the advantage of being able to better see which parts of the bowel get good blood flow. The theory is that good blood flow can reduce the risks of previously mentioned complications. This has been shown to be true in a variety of bowel surgeries in adults. ICG has also been shown to be safe in children. Given that HD and ARM are both relatively rare conditions (\~1/5000 live births), research in this area needs to be strategic. The investigators want to ensure that the investigators can recruit enough patients to the study using this protocol such that if this were to be scaled up to a multi-centre trial in the future, the investigators could demonstrate feasibility. The investigators will collect data both on the feasibility of recruitment as the primary outcome and secondary outcomes including stricture, leak, length of stay in hospital, and return to hospital.

The goal of this clinical trial is to compare protein supplements in patients with kidney failure on dialysis. The main questions it aims to answer are: * To determine whether the supplementation of egg white protein pudding in a population of individuals with kidney failure on dialysis is feasible. * To determine whether egg white protein pudding supplementation improves serum albumin similar to other standard nutritional supplements. * To determine the effects of the egg white protein pudding on frailty measures, dietary intakes and analytes in the blood. Participants will receive either the egg white pudding (experimental) or control (Ensure plus) at the end of their dialysis treatments 3-days per week for 12 weeks.

This randomized study will compare the effect of fecal transplant or placebo, in persons with ulcerative colitis. Participants will be grouped into either: Adjunct therapy group (add to current therapy) or Co-Administration group (those initiating or switch to a new advanced agent). Participants will take oral pills for up to 24 weeks to see if fecal transplant may be lead to remission faster and/ or prevent patients from having to switch therapies. Participants will be followed up to 24 weeks in duration. Several questionnaires will also be administered. Samples, including blood, stool and colonic biopsies will also be collected so the researchers can better understand which microbes are important.

Work-related shoulder pain is a common problem with significant socio-economic repercussions. The impact of these disorders on workers is considerable, particularly in terms of pain, disability and reduced quality of life. Several occupational factors may explain the onset of these disorders, such as changes in the work environment, physical demands, psychosocial factors specific to the occupational context and the age of workers. The lack of quantitative measurement tools to assess the physical demands of work over an extended period of time is sorely felt. Recently, our team developed a wearable feedback device, similar to a watch worn on the arm, which measures shoulder movements and muscle activity, transforming this real-time data into clinical indicators. These indicators provide immediate feedback to workers, enabling them to better understand the physical demands of their tasks and adapt accordingly. If this device proves effective in reducing physical demands, it could become a valuable tool for guiding workplace assessments and interventions. However, this device has not yet been tested on workers with shoulder pain. For this reason, a two-part pilot study is needed to understand user needs, assess ease of use and the feasibility of implementing the device. The first component will consist of a pilot clinical trial involving 42 workers suffering from shoulder pain, divided into two groups: one group will use the feedback device for 2 weeks, while the other group will continue to work without intervention. The second phase will analyze the experience of participants who have used the device.

There is no consensus about the best bowel preparation prior to transanal endoscopic surgery TES). Cleanliness and visibility in the rectosigmoid and rectum are of utmost importance, possibly even more so than during colonoscopy, to facilitate safe, precise and efficient resection of the rectal lesion and potentially adequate closure of the defect. Both Fleet enemas and oral mechanical bowel preparation are considered standard of care in preparation for TES. This single center two arm single blinded randomized controlled trial will compare the effectiveness of Fleet enemas in comparison to Pico Salax oral mechanical bowel preparation in cleansing the rectum as measured by a modified version of the Ottawa Bowel Prep Scale.
