Whether you are healthy or have a medical condition, there are opportunities to participate in a research study. Health research ranges from simple questionnaires or screening tests, to clinical trials of a new drug or device.
The purpose of this study is evaluate the safety and efficacy of a new vaccine to protect children against bacteria that can lead to pneumococcal disease.
The purpose of this study is to determine the lung and immune function benefits of stopping vaping for 72 hours in young adults who use e-cigarettes containing nicotine. The study also aims to determine if telling participants of their own personalized changes to their lung and immune function following the 72 hour abstinence period affects their motivation in quitting vaping.
The purpose of this study is to assess the effects of the COVID-19 outbreak and related quarantine measures on the physical and mental well-being of health care workers, as well as the general population.
The purpose of this study is to examine the safety of running for knee joint health through an assessment of running biomechanics and MRI-derived measures of cartilage composition.
We would like to explore different aspects of sexual identity among individuals who self-identify as asexual, bisexual, gay or heterosexual.
The goal of the current study is to determine the prevalence, rate, and types of pregnancy complications and early life events that may be associated with the emergence of psychosis and related metabolic disorder in patients with schizophrenia spectrum disorders.
To determine how much noise is required during testing to make sure that each ear is assessed separately during an auditory assessment in infants.
This is an observational study designed to determine the relationship between quantitative advanced MRI measures and OCT with PET measurements of microglial activation and myelin health.
The AMPLATZER LAA Occluder is a transcatheter, self-expanding nitinol device intended for use in preventing thrombus embolization from the LAA. The purpose of this study is to compile real world outcome data on the use of AMPLATZER LAA Occluder in subjects with non-valvular atrial fibrillation (NVAF)
To determine the effects of aerobic exercise on hippocampal volumes and severity of psychotic symptoms in a population of psychosis patients compared to healthy age/gender matched volunteers. Psychosis patients often suffer from a number of cognitive difficulties, including poor memory function, poor problem-solving capacity and difficulties with attention and concentration. These problems are not well addressed by current clinical treatments.
People who may be at increased risk of lung cancer due to age and smoking history will be invited to participate in this international study to determine the best way of using computed tomography (CT) of the chest to screen for early lung cancer. Overseas data show that CT screening (screening tests can find diseases early, when they're easier to treat) can reduce deaths from lung cancer and this study will help determine who is most likely benefit from screening.
This study will maximize identification of women with Lynch Syndrome using an enhanced screening strategy to identify those at risk. These women will be referred to genetic counselling for testing and those found to have Lynch Syndrome will be asked to invite first degree relatives to participate and undergo genetic testing for Lynch Syndrome.
The purpose of this study is to examine the effects of Parkinson's medication on decision making and risk taking in healthy control participants.
This study will test the safety and tolerability of a medium chain triglyceride (MCT) supplement in those with Alzheimer Disease (AD).
This study is a 12-month study. There are two different groups in the study. Both groups will enter the study after the graduation from 8-hour diabetes education course taught at VGH, St. Paul's, or Richmond Hospital. The first group will receive on-going support from their peers who have diabetes and are trained specifically to help other patients with diabetes. The second group will receive the usual care.
Patient failure to take medications as prescribed (medication non-adherence) is now identified as an important cause of kidney transplant failure. The availability of new drugs that are taken once daily may improve patient adherence compared to older drugs that had to be taken twice per day. In this study, patients will be converted to a medication schedule where all medications are taken once daily with the goal of improving patient adherence and satisfaction.
The purpose of this study is to assess the safety, tolerability, biomarker and cognitive efficacy of investigational products in subjects who are known to have, or are at risk of having an Alzheimer's disease-causing mutation by determining if treatment with the study drug slows the rate of progression of cognitive impairment and improves disease-related biomarkers.
This study also offers an observational component collecting cognitive assessment data until the availability of an enrolling drug treatment group, referred to as cognitive run-in (CRI).
This double-blind crossover study aims to compare cognitive performance (e.g., working memory, selective attention and cognitive flexibility) of children ages 6-18 years diagnosed with ADHD of the combined type (ADHD-C) or inattentive-type (ADHD-IA) and currently on > 20 mg/day of psychostimulants (psychostimulants) on: a) their current dose of psychostimulants, vs. b) a lower-dose of psychostimulants (half of their current dose).
Percutaneous nephrolithotomy (PCNL) is a surgical procedure that is standard of care for the removal of large kidney stones. PCNL involves removal of the stone(s) from the kidney through a temporary tract that is percutaneously placed through the patient's back during surgery. There is a significant risk of urinary tract infection after PCNL but wide clinical variation in use of prophylactic antibiotics in the days leading up to surgery.
The purpose of this study is to add to the investigators' quest to understanding stone disease, by evaluating the metabolites excretion in urine and its relation to microflora present in the stool.
