The percentage of loss time claims receiving Loss of Earnings benefits at 3 months has continued to rise amongst injured workers in Ontario despite the Workplace Safety and Insurance Board (WSIB) approach of "Better at Work". The primary health services to address loss time claims associated with musculoskeletal injuries include the evidenced-based programs of care, occupational health assessment program and musculoskeletal specialty programs, however, these are set to be revised and relaunched in Q1 2023. Across treatment protocols there are challenges that, at least in part, appear to contribute to the increasing percentage of workers on full loss of earnings at 3 months include (1) inconsistent early identification of workers who should be triaged to various health services and (2) reliable determination of the optimal timing of referral to the most targeted care to enable a safe and sustainable return to work. The investigators aim to develop and evaluate a predictive assessment model to triage workers to the best service within the first 8 weeks of their claim to increase the rate of early return to work, with the long-term goal that the triage protocol becomes part of a person-centric protocol that reduces the duration of work-related disability. The investigators will develop and evaluate an assessment protocol for injured workers that enter any of the musculoskeletal-specific WSIB programs of care, which have been consolidated into a single program as of 2023. This study will be a prospective inception cohort design using data collected from injured workers receiving WSIB musculoskeletal programs of care services at CBI Health clinics in Ontario Canada. Worker data will be collected at intake to the program of care service and again approximately four and eight weeks after intake (or earlier if a worker completes the program of care). The investigators will complete data analysis in three steps including descriptive and bivariate associations, Maximum Likelihood-based Latent Profile Analysis, and evaluation of results against successful work outcomes and secondary outcomes. Qualitative data will be mined for alternative indicators of recovery / non-recovery. The study recruitment goal is 300 - 350 workers with complete follow-up within a 2-year period.

Today, the majority of gallbladder removals surgeries are done using minimally invasive techniques through small cuts to help patients recover faster. However, these procedures are technically more challenging because surgeons have a restricted view of the patient's anatomy, which can increase the risk of serious complications. Artificial intelligence (AI) tools have been developed to guide surgeons during surgery and help them make safer decisions that reduce the risk of injury to the patient. This study will use a randomized controlled trial to compare outcomes between surgeries with AI assistance and standard procedures without AI. Primary Objective: To determine whether the AI improves surgeons' ability to achieve the Critical View of Safety, a key step for safe gallbladder removal, compared to standard procedures. Secondary Objectives: * Determine whether the AI helps the surgeon perform more safe dissections compared to the standard procedures. * Collect surgeon feedback on the use of AI during the procedure

Despite lung transplantation (LTx) being the most effective treatment for end-stage lung disease, its success rate is lower than that of other solid organ transplantations. Primary graft dysfunction (PGD) is the most common post-operative complication and a major factor in early mortality and morbidity, affecting \~25% of lung transplant patients. Induced by ischemia reperfusion, PGD represents a severe and acute lung injury that occurs within the first 72 hours after transplantation, and has a significant impact on short- and long-term outcomes, and a significant increase in treatment costs. Any intervention that reduces the risk of PGD will lead to major improvements in short- and long-term transplant outcomes and health care systems. One of the main strategies to reduce the risk and severity of post-transplant PGD is to improve pre-transplant donor lung preservation methods. In current practice, lung preservation is typically performed by cold flushing the organ with a specialized preservation solution, followed by subsequent hypothermic storage on ice (\~4°C). This method continues to be used and applied across different organ systems due to its simplicity and low cost. Using this method for the preservation of donor lungs, the current maximum accepted preservation times have been limited to approximately 6-8h. While the goal of hypothermic storage is to sustain cellular viability during ischemic time through reduced cellular metabolism, lower organ temperature has also been shown to progressively favor mitochondrial dysfunction. Therefore, the ideal temperature for donor organ preservation remains to be defined and should maintain a balance between avoidance of mitochondrial dysfunction and prevention of cellular exhaustion. In addition to that, safe and longer preservation times can lead to multiple advantages such as moving overnight transplants to daytime, more flexibility to transplant logistics, more time for proper donor to recipient matching etc. Building on pre-clinical research suggesting that 10°C may be the optimal lung storage temperature, a prospective, multi-center, non-randomized clinical trial was conducted at University Health Network, Medical University of Vienna and Puerta de Hierro Majadahonda University Hospital. Donor lungs meeting criteria for direct transplantation and with cross clamp times between 6:00pm - 4:00am were intentionally delayed to an earliest allowed start time of 6:00am and a maximum preservation time from donor cold flush to recipient anesthesia start time of 12 hours. Lungs were retrieved and transported in the usual fashion using a cooler with ice and transferred to a 10°C temperature-controlled cooler upon arrival to transplant hospital until implantation. The primary outcome of this study was incidence of Primary Graft Dysfunction (PGD) Grade 3 at 72h, with secondary endpoints including: recipient time on the ventilator, ICU Length of Stay (LOS), hospital LOS, 30-day survival and lung function at 1-year. Outcomes were compared to a contemporaneous conventionally transplanted recipient cohort using propensity score matching at a 1:2 ratio. 70 patients were included in the study arm. Post-transplant outcomes were comparable between the two groups for up to 1 year. Thus, intentional prolongation of donor lung preservation at 10°C was shown to be clinically safe and feasible. In the current study design, the investigators will conduct a multi-centre, non-inferiority, randomized, controlled trial of 300 participants to compare donor lung preservation from the time of explant to implant at \~10°C in X°Port Lung Transport Device (Traferox Technologies Inc.) vs a standard ice cooler. When eligible donor lungs become available for a consented recipient, the lungs will be randomized to undergo a preservation protocol using either 10°C (X°Port Lung Transport Device, Traferox Technologies Inc.) or standard of care. The primary outcome of the study is incidence of ISHLT Primary Graft Dysfunction Grade 3 at 72 hours. Post-transplant outcomes will be followed for one year.

Goals: The long-term use of hormonal birth control has been shown to effect glucose handling, or blood sugar regulation, and potentially lead to insulin resistance which increases a person's risk for metabolic diseases such as type 2 diabetes. The goal of this study is to investigate how the body handles glucose, in three groups of young, healthy females: NAT (naturally cycling, or not using hormonal birth control), OCP (taking a birth control pill), and IUD (using an intrauterine device). Objectives: We will investigate if the body's ability to handle glucose differs between these groups. We will also explore if these differences are linked to the levels of primary sex hormones in females, estrogen and progesterone, and if the synthetic versions produced by hormonal birth control have the same negative effect. We will use an oral glucose tolerance test to investigate these potential differences, having participants drink a 75 gram glucose beverage and taking blood samples every 15-30 minutes for a 2-hour timespan. These blood samples will be used to measure glucose and insulin levels in the blood to determine any changes that occur in the body in response to glucose.

Rheumatoid arthritis is a disabling arthritis that affects young women disproportionately. Although the physicians have some excellent treatments, they do not know which treatment is best for which patient. The investigators want to find ways to identify the right drug for the right patient at the right time. This is what personalized medicine is all about.

This observational study investigates an Internet-delivered Cognitive Behaviour Therapy (ICBT) intervention for alcohol misuse, called the Alcohol Change Course Enhanced (ACCE). The intervention will be offered through the Online Therapy Unit, which is a routine care ICBT clinic. The primary objective of the study is to examine whether engagement in adaptive actions measured by the Things You Do Questionnaire (TYDQ), including healthy thinking, meaningful activities, social connections, healthy habits and goal setting - increase during ICBT for alcohol misuse. Using data collected during routine care, the relationship between adaptive actions and alcohol use will be investigated, and specifically explore if the frequency of adaptive actions increases as alcohol use reduces during the intervention.

Growing evidence has supported rapid and robust antidepressant effects with subanesthetic doses of intravenous (IV) ketamine for treatment resistant depression (TRD). However, no completed or ongoing RCTs have evaluated the effects of repeated doses of IV ketamine for a homogenous sample of patients with treatment-resistant bipolar disorder depression (TRBD). The primary research goal is to determine the acute antidepressant efficacy, safety and tolerability of repeated sub-anesthetic maintenance doses of IV ketamine in, over a period of twelve weeks. Open-label ketamine infusions will be provided on a flexible schedule (every 2-4 weeks) with flexible dosing (0.5-1.0mg/kg over 40 minutes) titrated to optimize benefits, while minimizing the dosage and frequency over a 12-week extension period. All patients participating in this open-label study will have completed an acute course of infusions in a parent two-site, phase II, double-blinded midazolam-controlled RCT trial. In addition to this acute course of four infusions, a maximum of six infusions will be provided over the 12-week period. Secondary aims include evaluating effects of IV ketamine on suicidal ideations, quality of life, function and duration of effects. Herein, a two-site (University Health Network and Ontario Shores Centre for Mental Health Sciences), single-arm, open label, 12-week extension trial evaluating the effects of flexibly-dosed adjunctive ketamine infusions for TRBD to maintain antidepressant effects in participants who achieved an antidepressant response (MADRS decrease by \>50%) or remission (MADRS \< 12) following an acute course of four ketamine infusions is proposed. The primary outcome will be Montgomery-Åsberg Depression Rating Scale (MADRS) scores, determining by a linear mixed model from baseline to week 12. Secondary outcomes include evaluating response and remission rates, safety, tolerability (including treatment-emergent mania), and effects on suicidality, anxiety, quality of life, function and the duration of effects.
