Comparing Cardiac Chamber Measurements: TTE vs. TEE Under Anesthesia
This study aims to compare two common ultrasound techniques used during heart surgery: transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE). TTE is performed by placing an ultrasound probe on the chest, while TEE involves inserting a probe into the esophagus, which provides closer and clearer images of the heart. Both …
The Simplify Project
The high frequency of unplanned hospital visits of patients with chronic hypercapnic respiratory failure (e.g., chronic obstructive pulmonary disease, obesity-related hypoventilation) constitutes a major public health problem. Most patients admitted for acute exacerbations (AHRF) have additional comorbidities, especially sleep disorders. Often untreated, sleep disorders contribute to multiple readmissions (≈70% at …
Immune Checkpoint Inhibitor Therapy for Cancer and Risk of Myocarditis or Cardiomyopathy
Patients undergoing dual treatment with Immune checkpoint inhibitors (ICI) for various cancers, e.g. melanoma, are at increased risk of developing myocarditis and cardiomyopathy. Currently, only limited data on serial myocardial tissue changes during treatment and whether they predict outcomes are available. Cardiac MRI (CMR) is the reference standard for non-invasive …
Targeted Deprescribing in Patients on Hemodialysis
Hemodialysis (HD) patients take more pills per day on average than any other chronically ill patient population. On average, an HD patient takes 19 medications per day, of which 70% may not be appropriate. The reason the medications may not be appropriate is that HD patients are rarely included in …
Mpox Prospective Observational Cohort Study
The goal of this multicentre prospective observational cohort study is to shed light on the following unknowns: The clinical manifestations of Mpox infection since the 2022 outbreak in Canada. The social and psychological impacts of Mpox infection since the 2022 outbreak in Canada The transmissibility of Mpox infection Viral shedding …
Diagnosis of Graft Pathology by TruGraf
The goal of this observational study is to to identify different causes of liver diseases or damage in liver transplant patients and develop a machine learning algorithm as a non-invasive tool leveraging gene expression and patient clinical information to classify transplant liver diseases We will collect blood samples of the …
MR Guidance for Liver and Pancreas
This is a single centre, single arm, prospective feasibility study that aims to see whether magnetic resonance imaging (MRI) as a source of image guidance before each radiation treatment fraction is feasible, and also if it may provide information that could potentially be used during the treatment to improve the …
Examining the Effects of Nasal High Flow Oxygen Therapy Compared to Non-invasive Ventilation in Health Volunteers
Respiratory failure is characterized by low levels of oxygen and high levels of carbon dioxide in the blood which causes difficulty breathing. The management of patients with respiratory failure aims at improving oxygenation, and decreasing the effort required to breathe. Mechanical ventilation is a life-saving treatment, but may be associated …
Molecular Characteristics of Gastroesophageal Adenocarcinoma (MOCHA): A Prospective Feasibility Study
Researchers are looking to further our knowledge on disease biology and treatment selection for gastroesophageal adenocarcinoma. The purpose of this study is to see how useful it is to look for changes and characteristics in your genes (molecules that contain instructions for the development and functioning of the cells) and …
Intra-operative Evaluation of the External Ventricular Drain Catheter Position With Structured Light for Patients (Bullseye EVD)
The placement of external ventricular drainage (EVD) is a life-saving procedure used to relieve high pressures in the brain. Often performed at the bedside, a small tube (catheter) is inserted into one ventricle of the brain to drain cerebrospinal fluid and release the pressure build up. In standard practice, EVDs …
