This study aims to evaluate the surgical technique used in Abdominal Normothermic Regional Perfusion (A-NRP) in death determination by circulatory criteria (DCC) organ donors. The proposed study will demonstrate that there is no resumption of brain blood flow or activity during the A-NRP procedure. This will be assessed using multimodal neuromonitoring protocol that enables continuous focused monitoring of brain blood flow and activity during A-NRP. This will provide evidence that brain blood flow and activity does not resume during NRP and ensure donor safety in using this technique in standard of care practice.

This study aims to compare two different protocols commonly used in the management of post thyroidectomy hypoparathyroidism : PTH based calcium repletion and empiric repletion. The investigators aim to compare the quality of life associated with these two protocols in a randomized trial.

The RELEARN trial is a a prospective longitudinal cohort study sampled by convenience. Stroke survivors and healthy control individuals will be recruited to analyze motor learning in the upper extremity and its neural basis in early stroke recovery.

This is an open-label, multicenter, Phase 1/2 study evaluating the Safety, Tolerability, and Efficacy of VCTX211 Combination Product in Subjects with T1D

Insertion of a central venous access device (CVAD) allows clinicians to easily access the circulation of a patient to administer life-saving interventions. Due to their invasive nature, CVADss are prone to complications such as infection, bacterial biofilm production, and catheter occlusion due to a thrombus. A CVAD is placed in up to 97% of patients in the intensive care unit, exposing this vulnerable population to risk of nosocomial infection and occlusion. Current standard of care involves use of normal saline (for CVCs and PICCs) or citrate (for hemodialysis catheters) as a catheter locking solution. CVAD complications remain a problem with current standard of care. 4% tetrasodium Ethylenediaminetetraacetic acid (EDTA) fluid (KiteLock Sterile Locking Solution) possesses antimicrobial, anti-biofilm, and anti-thrombotic properties and is approved by Health Canada as a catheter locking solution. As such, it may be superior CVC locking solution than the present normal saline or citrate lock. To our knowledge, the efficacy of an EDTA catheter locking solution has not yet been investigated in the intensive care patient population. Our team proposes to fill this knowledge gap by performing a multi-centre, cluster-randomized, crossover study evaluating the impact of KiteLock Sterile Locking Solution on a primary composite outcome of CLABSI, intraluminal occlusion, and alteplase use in the ICU of six ICU's compared to the standard of care saline lock.

The goal of this observational study is to learn about the comparative acute effects of ketamine vs esketamine in participants over the age of 18 for the treatment of their severe depression and suicidal ideations. Participants are already taking antidepressants and/or antipsychotics as part of their regular medical care for depression,

Recent research has demonstrated that a hemiarthroplasty (replacement of half the joint) has lower rates of post-surgical complications than a total hip arthroplasty does. However, surgeons tend to vary in their approach to hemiarthroplasties. The lateral approach, which involves making an incision at the side of the patient's hip, requires surgeons to cut through the muscle to access the hip, which has been associated with greater muscle damage and slower rates of recovery. On the other hand, the direct anterior approach does not require the cutting of the patient's muscle and is therefore associated with minimal muscle damage and faster rates of recovery. This study will aim to assess the impact of the surgical approach (Direct Anterior Approach vs. Lateral approach) during hemiarthroplasty on patients' short-term mobility, quality of life, function, pain, and safety parameters.

Spastic ataxias are a group of diseases causing symptoms such as walking difficulties and balance impairments that lead to a high risk of falls. No pharmacological treatments exist to treat these diseases. Unfortunately, little effort is made to develop non-pharmacological treatments specific to spastic ataxias despite the detrimental impact of the disease on several aspects of an individual's life and the high cost of falls for society each year. The three objectives of this project are: 1) to determine the effect of a 12-week rehabilitation program on disease severity as compared with usual care for individuals with spastic ataxias; 2) to identify which factors can help (or not) the implementation of the program in the clinical settings ("reel world"); and 3) to explore the cost-benefits of IMPACT \[rehabIlitation prograM for sPAstiC aTaxias\]. The team has developed the program to specifically target symptoms present in these patients and was previously pilot-tested. Based on the results obtained in this pilot project, positive effects are expected concerning the disease severity of participants. The investigators want, with this project, provide to health care professionals an option to offer better-suited services to people living with spastic ataxia worldwide.

Combined Phase II/III, multi-center, prospective, single-blinded trial. Ten (10) patients with essential tremor who previously underwent successful and uncomplicated GK thalamotomy for essential tremor will undergo a contralateral treatment. The incidence of side effects will be determined at 3 months postoperatively, graded per the CTCAE v5 and analyzed by a data safety monitoring board. Upon successful review, this Phase II trial will be converted to a Phase III trial of utility that will enrol 40 additional patients. The primary outcome will be the change in QUEST score at 12 months postoperatively, as well as a patient-reported assessment of Health Utility. Secondary outcomes will include objective tremor, gait and speech assessments (filmed and scored by blinded evaluators), as well as quality of life questionnaires and adverse events questionnaires. Outcomes will be assessed at baseline, as well as 3, 6, 12, 24 and 36 months post-operatively.

The Sunnybrook Type 2 Diabetes Study (S2DS) is a prospective observational study of people with prediabetes or Type 2 Diabetes Mellitus (T2DM), that aims to understand the aetiologies, manifestations, and clinical consequences of mood and cognitive complications. The study recruits from the services at Sunnybrook Health Sciences Centre and from the neighbouring University Health Network Toronto Rehabilitation Institute Cardiac Rehabilitation Program.
