The goal of this prospective controlled study is to measure the reliability of two intraocular pressure (IOP)-measuring instruments in comparison to the gold standard, Goldmann applanation tonometry (GAT) following vitreo-retinal surgery. The main question the current study aims to answer is: are Icare and Accupen as accurate as GAT in measuring IOP one day post eye surgery? Participants in this study will have their IOP measured by the three different instruments one day post-surgery. Read Less

The chemotherapy medications used for breast cancer treatment are important for achieving a cure, but a potential side effect is that they can cause a decline in functional capacity (reduced exercise tolerance and impaired physical function) and increase the risk of cardiovascular disease. The risks of decreased functional capacity and cardiovascular disease are highest in breast cancer survivors as they grow older. The factors causing the decline in functional capacity are not well understood, however they may be related to a reduction in cardiac function (e.g. decreased pumping ability of the heart) or skeletal muscle function (reduced muscle blood flow and oxygenation). Exercise training is used for other populations at risk for cardiovascular disease (such as cardiac rehabilitation), but is not routinely offered to breast cancer survivors. Therefore this research study wants to test whether exercise training can improve heart and muscle health, and increase functional capacity in up to 60 older breast cancer survivors aged \>60 years old who previously received chemotherapy drugs that can affect the heart. The purpose of this study is to compare two rehabilitation approaches: a 12-week structured exercise training program or a 12-week stretching-yoga program. The investigators want to compare whether these programs can improve functional capacity, and heart and skeletal muscle function. To do this, some of the participants in this study will be randomly enrolled in the structured exercise training program and others will be randomly enrolled in the stretching-yoga program.

This study will establish a non-invasive diagnostic approach and evaluate clinical outcomes for children at high-risk for pulmonary invasive fungal infection (PIFI). Read Less

This is a Phase II prospective sing-arm trial that is recruiting 60 participants from patients that have biochemical failure after radical prostatectomy with local or regional recurrence proven by PSMA PET. Participants of this study will receive molecular imaging informed radiation dose escalation to site of recurrent disease and de-escalation to uninvolved areas. Participants will be follow-up as per standard of care up to 5 years post-treatment. Read Less

The goal of this randomized controlled trial is to test if a patient navigator program improves healthcare experiences and outcomes for migrant families caring for a child or youth with special healthcare needs (i.e. chronic health condition). The main questions are, for migrant families with a child or youth with special healthcare needs: Does a patient navigator reduces barriers to care? Does a patient navigator improve care coordination, caregiver empowerment, caregiver stress and quality of life? What are the healthcare experiences for families with and without the patient navigator intervention? Participants will: * Receive the intervention, i.e., the patient navigator program, or continue with standard of care for 12 months * Fill out questionnaires at 3 time points on barriers to care, caregiver stress, care coordination, and their child's health Read Less

This is a phase I dose-escalation study of oral PCLX-001, conducted in a multicenter, non-randomized, open-label, non-controlled design. The study is comprised of two parts: Part A (single-agent dose escalation) and Part B (single-agent expansion cohorts). Read Less

Double blind, double dummy trial of the use of IV acetaminophen versus oral acetaminophen for the prevention of delirium after cardiac surgery. The underlying hypothesis is that better pain control and less use of narcotics will lead to a lower incidence of delirium from day 1 to 7 following cardiac surgery. Other important secondary outcomes are the total use of narcotics, ICU and hospital stay, improved cognitive function at 6 months and 1 year post surgery, NSAID use at each centre and associated NSAID complications.

Myocarditis and pericarditis are inflammatory diseases of the myocardium and pericardium, and can be related to different causes, including vaccines. In the past, some people developed inflammatory heart disease after receiving a live or inactive virus vaccine (smallpox vaccine or flu vaccine). Myocarditis was also seen in people with COVID-19. More recently, many countries reported that some people have developed an inflammatory condition of the myocardium or pericardium after receiving a vaccine for COVID-19. After the COVID-19 vaccination campaigns, doctors have noticed more people presenting to the Emergency Department with chest pain and shortness of breath after receiving the vaccine, symptoms that resemble myocarditis or pericarditis. These symptoms may start between 2 to 10 days following vaccination and are frequently noticed after the second dose of the vaccines. While pericarditis seems to affect people of various age groups and gender, myocarditis is more commonly seen in young males. The study will consist of two components. 1) The vaccine-induced inflammatory heart disease database will be established. There will be a retrospective chart review looking at vaccine myocarditis/pericarditis (Brighton Criteria Levels 1-3). 2) There will be a prospective, pragmatic design case-control study for vaccine myocarditis/pericarditis. Follow-up telephone interview will be conducted at 6 months, 12 months and yearly up to 4 years. A record search will also be performed at 6 months, 12 months and yearly for 4 years. The retrospective component of the study will be conducted by identifying patients previously diagnosed with this condition at participating centres. Read Less

Ankle sprains are the most common musculoskeletal complaint of children presenting to the emergency department (ED). Healing can often be protracted, leading to prolonged pain, missed school and work, and delayed return to a normal activity level. Smartphone apps have been shown to be associated with greater caregiver knowledge and improved outcomes in a number of conditions but have not been explored in ankle sprains. We would like to know if using a smartphone app for children with ankle inversion injuries leads to improved functional outcomes such as pain, mobility, and return to activity. We will be comparing a smartphone app that provides education and daily management reminders to a paper handout to see if the former leads to improved functional recovery. Read Less

Difluoromethylornithine (DFMO) will be used in an open label, single agent, multicenter, study for patients with neuroblastoma in remission. In this study subjects will receive 730 Days of oral difluoromethylornithine (DFMO) at a dose of 750 mg/m2 ± 250 mg/m2 BID (strata 1, 2, 3, and 4) OR 2500 mg/m2 BID (stratum 1B) on each day of study. This study will focus on the use of DFMO in high risk neuroblastoma patients that are in remission as a strategy to prevent recurrence. Read Less

The present study is an investigator initiated, single-centre, prospective, proof-of-concept cohort study aiming to enroll 44 patients with acute middle cerebral artery (MCA) ischemic stroke, involving the right (n=22) and left (n=22) MCA territories and 24 control patients with acute focal neurological symptoms but no evidence of acute brain infarct on DWI-MRI.

The primary purpose is to compare the effects of creatine supplementation (bolus ingestion of 5 grams vs. 3 grams) during 16 weeks of resistance-band training on measures of body composition (i.e., whole-body lean tissue mass, total body water), arm and leg muscle thickness (growth), muscle performance (i.e., power, strength, endurance) and functional ability (i.e., walking speed, balance). A secondary purpose of this research is to examine the effects of bolus ingestion of creatine (5 grams) compared to intermittent ingestion of creatine (2 x 2.5 grams) during 16 weeks of resistance-band training on measures of body composition (i.e., whole-body lean tissue mass, total body water), arm and leg muscle thickness (growth), muscle performance (i.e., power, strength, endurance) and functional ability (i.e., walking speed, balance).
