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 …
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 …
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 …
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 …
Investigation of Ultrasound Imaging and Spectroscopy for Characterizing Breast Masses
Our objective in this study is to identify an optimal set of quantitative ultrasound parameters that can be used, non-invasively, to characterize breast masses with high accuracy, as determined histopathologically. Breast cancer is the most frequent form of non-epithelial cancer diagnosed in women, with approximately 1.5 million new cases diagnosed …
Selective Fetal Growth Restriction in Monochorionic Twins - an International Investigation
Optimal diagnostic management and underlying pathophysiological mechanisms of selective fetal growth restriction (sFGR) in monochorionic diamniotic (MCDA) twin pregnancies have not been fully clarified. The current diagnostic classification system based on three different umbilical artery flow patterns has no increasing scale of severity and the predictive value is limited. Since …
Biliary Atresia Study in Infants and Children
Little is known about the factors that cause biliary atresia nor the factors that influence disease progression. The purpose of this study is to collect the pertinent clinical information, genetic material and body fluid samples to enable investigators to address the following aims: To identify the gene or genes implicated …
