Dopamine vs. Norepinephrine for Hypotension in Very Preterm Infants With Late-onset Sepsis
Fluid-unresponsive hypotension needing cardiotropic drug treatment is a serious complication in very preterm neonates with suspected late-onset sepsis (LOS; defined as culture positive or negative bloodstream infection or necrotizing enterocolitis occurring >48 hours of age). In Canada, ~250 very preterm neonates receive cardiotropic drugs for LOS related fluid-unresponsive hypotension every …
Liquid Biopsy Evaluation and Repository Development at Princess Margaret
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 Centre. Circulating cell-free nucleic acids (cfNA), including cell-free DNA (cfDNA) and …
Sex and Gender-based Analysis of the Effectiveness of Advanced Therapies in Psoriatic Arthritis
Sex and gender are important factors that influence treatment response in PsA. The goal of this multi-centre observational study is to understand how sex and gender influence response to advanced therapies in psoriatic arthritis (PsA). The investigators hope to discover biological and socio-cultural mechanisms that explain the differences in treatment …
Canadian Fabry Disease Initiative (CFDI) National Registry
CFDI NATIONAL REGISTRY Fabry disease is a rare, inherited, genetic condition due to a deficiency of an enzyme called alpha-galactosidase A. This enzyme deficiency causes the small blood vessels to accumulate a substance called glycolipid. Without sufficient levels of the enzyme, alpha-galactosidase A, persons with Fabry Disease develop severe neuropathic …
The European Paediatric Network for Haemophilia Management ( PedNet Registry)
Rationale Haemophilia is a rare disease; to improve knowledge international collaboration is needed. Well-defined clinical data will be collected from complete cohorts in order to prevent selection bias.

A Prospective Database of Infants With Cholestasis
Biliary atresia, idiopathic neonatal hepatitis, and specific genetic cholestatic conditions are the most common causes of jaundice and hyperbilirubinemia that continue beyond the newborn period. The long term goal of the Childhood Liver Disease Research Network (ChiLDReN) is to establish a database of clinical information and plasma, serum, and tissue …
Novel MRI Biomarkers for Monitoring Disease Progression in ALS
Routine MRI is normal in motor neuron diseases such as ALS. However, advanced MRI techniques can provide an objective measure of degeneration (a "biomarker") by examining brain structure, wiring, chemistry, and function. We will develop and evaluate novel MRI techniques that could improve our understanding of ALS and provide a …
Studying Health Outcomes After Treatment in Patients With Retinoblastoma
This trial studies health outcomes after treatment in patients with retinoblastoma. Gathering health information over time from patients and family members through vision assessments, samples of tissue and saliva, and questionnaires may help doctors learn more about what causes retinoblastoma, identify long-term health outcomes for patients with retinoblastoma, and find …
Real-World Evidence in Patient-Reported Outcomes for Medical Cannabis (MC-RWE)
This prospective observational study aims to describe the effectiveness of MC on pain, epilepsy, sleep and /or anxiety/depression in a cohorts of patients authorized to use MC, using pre-defined, validated self assessment scales.
Fetal Ebstein Anomaly and Tricuspid Valve Dysplasia Registry
Ebstein anomaly and tricuspid valve dysplasia (EA/TVD) are rare congenital tricuspid valve malformations that carry among the highest mortality of all congenital heart disease diagnosed in utero. Despite the high mortality associated with severe EA/TVD in the fetus, it has only been studied retrospectively. By prospectively enrolling a cohort across …
