Myocarditis is inflammation of the heart muscle. Pericarditis is inflammation of the lining surrounding the heart muscle. Symptoms of these conditions can include pain in the chest and rapid or irregular heartbeat. There are many different causes for myocarditis and pericarditis including COVID-19 infection. The MYCOVACC study will identify patients using local screening strategies, including research communications, care provider referrals, and medical record review. The retrospective component of the study will collect information about patients suffering from vaccine associated myopericarditis and COVID-19 associated myopericarditis. Consenting patients will then be prospectively followed according to standard of care protocols. The main objectives of MYCOVACC are to describe the rate of major adverse cardiovascular events, functional outcomes including quality of life, and myocardial recovery through imaging. Read Less

The main goal of this clinical study is to evaluate the safety of the Qidni/D Hemodialysis System in patients with end-stage renal disease. The main question it aims to answer is: Is the Qidni/D safe for performing hemodialysis? Participants will be subjected to one treatment of hemodialysis for up to 4 hours with the use of the Qidni/D.

The objective of this trial is to study the efficacy of treatment of human papilloma virus (HPV) related oropharyngeal cancer with chemotherapy followed by Transoral Robotic Surgery (TORS) as definitive treatment. Current treatment of oropharyngeal cancer are chemo-radiotherapy. There is significant lifelong side effects associated with this approach related to tissue effects of radiotherapy. The side effects results in significant quality of life deterioration among the patients. Overall there is 20% failure rate with this treatment approach. The study hypothesis is that treatment with upfront (neoadjuvant) chemotherapy followed by transoral surgery and neck dissection is highly effective treatment allowing competitive cure rate compared to chemo-radiotherapy with less than 10% failure rate, while avoiding radiotherapy in majority of cases. It is also hypothesized that better functional and quality of life outcome maybe achieved with this approach. Read Less

The purpose of this Phase I non-therapeutic trial is to examine the neurological effects of cannabis on stress reactivity and inhibition in healthy cannabis users. We expect differences between high ratio CBD:THC cannabis oil, low ratio CBD:THC cannabis oil, and/or placebo on outcome measures. Read Less

The Lung Clearance Index, measured by multiple breath washout, is a measure of lung function that is considered a research tool in Canada as the device used to measure it is not approved by Health Canada. The study will assess lung function in patients undergoing routine lung function testing for clinical indications (Cystic Fibrosis and Other Respiratory Diseases). In addition, healthy controls of different ages will be asked to perform this lung function test to gain reference data that can be used to interpret LCI in patients with lung disease. Read Less

Undescended Testis (UDT) is the most common congenital anomaly of the genitalia in boys and it is commonly managed by surgical intervention. Patients with intra-abdominal or non palpable testis, specifically, are often managed using a laparoscopic assisted orchidopexy, a common surgical technique to bring undescended testes down into the scrotum. Evidence in the medical literature to support the superiority of either one stage or two stage gubernaculum sparing laparoscopic orchidopexy (GSLO) is lacking. Due to this reason, this study focuses on the effects of one stage versus two stage GSLO on a patient important outcome: testicular atrophy. Read Less

In an aging population, most seniors suffer from multiple chronic conditions. When the number of medications taken is ≥5 (polypharmacy), the burden of taking multiple concurrent medications can do more harm than good. Seniors take an average of 7 regular medications and studies link polypharmacy with adverse effects on morbidity, function and health service use. However, it is not clear to what extent these are reversible if medication burden is reduced. This trial will test the effects on medication numbers and patient health outcomes of an intervention to polypharmacy. This study will test a program focused on medication reduction number and dose. Prioritizing medications according to the patient's preference as reducing the dose also reduces the risk of drug side effects. Patients, aged 70 years of age or older and are taking ≥5 medications, will randomly receive the program immediately or at 6 months. The program involves information gathering from the patient, including systematically seeking patients priorities and preferences medication review with the pharmacist and then a consultation with the family doctor. The intervention is focused on discontinuing/reducing the dose of medications where possible using a 'pause and monitor' framework to assess the need for restart. An electronic program that detects drug adverse effects and flags potentially inappropriate medications will be integrated into an electronic clinical pathway incorporating monitoring and follow up systems. This study will examine effects on patient and health relevant outcome measures as well as qualitative research exploring patients' and clinicians' experiences of reducing medication burden. The results will be used to determine whether this system can be implemented as part of routine preventative care in primary care for older adults. Read Less

Total knee arthroplasty (TKA) is a frequent performed surgery. Many institutions are implementing fast track programs for this surgery and adequate pain management is an important feature. Analgesic duration of single shot nerve blocks is limited to no more than 24h. Conversely, the use of continuous nerve block (CNB) through a perineural catheter and infusion of local anesthetic may increase duration of analgesia and provide better outcomes. The purpose of this study is to evaluate effectiveness and safety of using CNB in patients undergoing ambulatory TKA, and its effects on patients' quality of recovery. Investigators hypothesize that continuous adductor canal block would lead to decrease in opioid consumption in patients undergoing fast track TKA. Significance There are no published prospective randomized controlled trials to assess patient's reported quality of recovery after receiving CACB in same day primary knee arthroplasties. As this is a frequent type of surgery and has the prediction to increase its incidence for the next years, there is significant importance in investigations about interventions which may improve its recovery in a fast track regime. A postoperative analgesic technique that offers better pain control, has less adverse effects, reduces the opioid analgesia requirement and is safe to be used in a fast track setting may have additional impact on decreasing health care cost and may lead to an enhanced recovery and better quality of life. Objectives To evaluate effectiveness and safety of using CACB in patients undergoing ambulatory TKA, in comparison to SACB. Primary objective is opioid consumption (in oral morphine equivalent doses) Secondary objectives are to evaluate postoperative QoR-15 scores (10), pain scores, opioid-induced adverse effects (measured via validated opioid symptom distress scale), postoperative functional status, complications relating to the perineural catheter and readmissions.

Transcranial Ultrasound Stimulation (TUS) is an emerging non-invasive brain stimulation(NIBS) technique that can be used on both superficial and deep brain targets with a high spatial resolution as small as a few cubic millimeters. Functional Electrical stimulation is a peripheral stimulation technique researched and clinically used to restore motor function following conditions like stroke and Spinal cord injury. To date, there are no studies that have looked at the neuro modulatory effects of combining TUS and FES on motor symptoms in patients with Parkinson's disease. The current study aims to understand the neuromodulatory effects of combining tbFUS to bilateral primary motor cortex (M1) in Parkinsons's disease patients immediately followed by bilateral upper extremity FES of the hand muscles for improving motor symptoms.

This study evaluates the impact of intraoperative intravenous lidocaine administered during laparoscopic colorectal surgery on the intraoperative remifentanil consumption as well as postoperative pain and opioid requirements. It will evaluate immune cell activity for 48hours after surgical stress and general anesthesia with or without intravenous lidocaine. Read Less

Traditional randomized clinical trials (RCTs) have provided extremely valuable information on medical therapies and procedures that have changed the way heart diseases are treated. However, despite these contributions, traditional RCTs are costly, the findings may not be applicable to patients unlike those in the study, and the use of trial findings may be infrequent. These limitations may be addressed by incorporating 'big data' in RCTs, which is the emerging field using electronic information that is routinely collected in various large administrative health databases. The Community Heart Outcomes Improvement and Cholesterol Education Study (CHOICES) will test the potential of using 'big data' in a 'real-world' clinical trial to measure outcomes using routinely collected health information. CHOICES aims to increase the use of cholesterol-lowering statin drugs to prevent heart attack and stroke in high-risk health regions across Ontario using a 'toolbox' of interventions. The 'toolbox' of interventions are informational strategies targeted for both patients and family physicians to help improve cholesterol management and contribute to shared decision making for heart healthy goals.
