The objective of this protocol is to develop an institution-wide liquid biopsy protocol that will establish a common process for collecting blood and corresponding archived tumor specimens for future research studies at the University Health Network's Princess Margaret Cancer Cen…

X-linked myotubular myopathy (XLMTM) is a rare and serious condition present at birth where the muscles do not work properly. There are currently no therapies for this serious condition. The protein myotubularin is needed for muscle development and movement. A gene called MTM1 t…

Background: A heart catheterization is a diagnostic heart procedure used to measure pressures and take pictures of the blood flow through the heart chambers. Magnetic resonance imaging (MRI) fluoroscopy shows continuous pictures of the heart chambers that doctors can watch while…

Gadolinium-enhanced magnetic resonance imaging (MRI) is currently the imaging gold standard to detect active inflammatory lesions in multiple sclerosis (MS) patients. The sensitivity of enhanced MRI to detect active lesions may vary according to the acquisition strategy used (e.g…

Children with congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency tend to have elevated circulating levels of androgens, which can accelerate skeletal maturation and adversely impact adult height. Additionally, these children require supraphysiologic doses of hy…

Overutilization of intensive care unit (ICU) treatments among patients with advanced medical illnesses and poor prognosis places them at risk for prolonged suffering with minimal anticipated benefit. Improving communication and shared decision-making between providers and patient…

To identify preoperative factors influencing the duration of steroid replacement therapy after adrenalectomy/adrenal-sparing surgery in patients with non-ACTH-dependent hypercortisolism.

Adherence is a major problem for the approximately one-third of Americans over the age of 20 who suffer from Hypertension (HTN). Hypertension can be controlled through medication adherence and lifestyle modifications (diet and exercise). However, nearly 50% of those with HTN repo…

The proposed study is designed to test the hypothesis that in human obesity, the balance of pro- and anti-inflammatory T cells in fat tissue is in fact related to macrophage phenotype and insulin resistance, and how it is related. This study is needed to confirm whether conclusi…

Survivors of childhood cancer often suffer treatment-related toxicities, including chronic health conditions, high symptom burden and emotional distress, and decremented functional status and quality of life. Although some patient-reported outcome (PRO) tools are available for su…

The purpose of this study is to identify and distinguish two different types of Progressive Apraxia of Speech through clinical imaging and testing.

The aim of this project is to determine whether androgen deprivation therapy (ADT) decreases left ventricular function in prostate cancer patients. If found successful, this may lead to improved cardiovascular health via treatment and/or lifestyle interventions in prostate cancer…

Prospective Clinical Trial of HIV+ Living Donor Kidney Donation for HIV+ Recipients

Gastrointestinal (GI) dysfunction affects up to 50% of medical and surgical critically ill children. GI dysfunction, specifically gastric dysmotility and loss of epithelial barrier integrity, is associated with significant morbidity in critical illness. The mechanisms underlying …

The purpose of this study is to evaluate the efficacy and effectiveness of Behavioral Therapy (BT) and Cognitive Therapy (CT) in Gulf War Veterans with insomnia. The Primary Outcome measure is the Insomnia Severity Index (ISI).

Background: Genetic testing called "sequencing" helps researchers look at DNA. Genes are made of DNA and are the instructions for our bodies to function. We all have thousands of genes. DNA variants are differences in genes between two people. We all have lots of variants. Most …

This study is being done to collect medical and personal histories as well as a samples of blood, other body fluid and/or tumor/disease tissue for current and future research studies on histiocytic disorders.

Background: Follicular lymphoma is a type of cancer of the lymph nodes. Lab studies are important for cancer research. They help scientists better understand differences in the cancer biology of different patients. Researchers want to collect serial samples over time from people…

In this prospective longitudinal observational investigator-led single centre cohort study we will include patients undergoing cardio-CT for clinical reasons, to evaluate the role of cardio-CT terms of its diagnostic and prognostic value, as well as risk-benefit ratio. Particula…

Upper extremity allotransplantation is a new procedure which is becoming more common in the United States. Ongoing data collection for research purposes is vital to the long-term assessment as to the safety of the procedure and accompanying immunosuppression protocol, as well as …
