This is a phase II, open-label study to assess the efficacy of AZD2936 in terms of molecular residual disease (MRD) clearance and treatment outcome in patients with MRD after definitive treatment for high risk locoregionally advanced head and neck squamous cell carcinoma (LA-HNSCC). MRD is defined as ctDNA detection in plasma after definitive treatment. Approximately 200 patients are expected to be enrolled. Read Less

DO-IT is an international, multicenter, prospective, two-arm, randomized, open label, blinded endpoint superiority trial determining the safety and efficacy of intravenous thrombolysis (IVT) in participants experiencing an acute ischemic stroke (AIS) with recent (within the last 48 hours) intake of direct oral anticoagulant (DOAC). For this purpose, 906 adult participants experiencing an AIS with recent DOAC intake will be enrolled at several high-volume international stroke centers and randomly assigned in a ratio of 1:1 to one of two treatment arms: (1) IVT and standard of care/best medical treatment or (2) standard of care/best medical treatment. The DO-IT trial is a definitive test of the hypothesis that IVT is superior to standard of care for achieving better outcome at 90 days in AIS participants with recent DOAC intake. Read Less

Local muscle endurance (LME) is the ability of a muscle(s) to resist fatigue and is needed for daily activities of life such as climbing stairs, lifting/moving objects, and in sport contexts like rock climbing, mixed martial arts, cross-fit, kayaking and canoeing. Therefore, the investigators want learn how to improve LME and understand what in human bodies changes during exercise training to cause these changes. The investigators know that lifting weights improves muscle strength which is believed to improve LME. Specifically lifting less heavy weights (LLRET) for more repetitions leads to greater gains in LME opposed to heavier weights for fewer repetitions. Therefore, lifting less heavy weights likely causes greater changes in our muscles than lifting heavier weights that cause improvements in LME. Aerobic exercise preformed at high intensities in an interval format (HIIT) may also help improve LME by increasing our muscle's ability to produce energy during exercise. Therefore, the investigators want to see which of LLRET or HIIT leads to greater improvements in LME. Read Less

The goal of this registry is to learn more about cytolytic vaginosis, a little known and controversial condition. The main questions the registry aims to answer are: * What are risk factors of cytolytic vaginosis? * Are there defining symptoms of cytolytic vaginosis? * What features on wet mount should be used to diagnosis cytolytic vaginosis? * Are baking soda vaginal irrigations an effective treatment for cytolytic vaginosis? * Do characteristics of cytolytic vaginosis vary between sites/countries?

Inflammatory joint diseases are major causes of invalidity and morbidity. Rheumatoid arthritis (RA), the most frequent of chronic arthritides, affects close to 1% of the Canadian population. Direct and indirect costs of RA represent close to 1% of the gross national product. Recent evidence suggest that initiation of early (e.g., during the first 3-12 months of disease) aggressive treatment decreases both mortality and long term invalidity in RA and other chronic arthritides. However, a significant proportion of patients with early polyarthritis (EPA) have a benign evolution, even if they fulfill criteria for RA. On the contrary, most patients whose arthritis persist for more than 12 months have a progressive and destructive disease. Currently available clinical, serological and genetic markers of severity in arthritic patients perform poorly in EPA patients to identify those patients whose arthritis is likely to persist and thus who deserve an aggressive treatment. The Investigators propose a prospective and longitudinal study to define the contribution of detection of rheumatoid arthritis-specific autoantibodies (RASA), either alone or in combination with other markers of severity, in the prognostic evaluation of patients presenting with EPA. Availability of such an effective serological tool to establish prognosis in individual patients would improve therapeutic decisions in clinical practice. The same prognostic tools would represent very powerful instruments to subset patients into more homogeneous groups in clinical trials, increasing their power. Read Less

The objective is to observe the evolution of walking parameters during the surgery process and find which of all calculated walking parameters represent the best indicators of functional disabilities and postoperative recovery for patient with lumbar spinal stenosis. Read Less

While undergoing chest wall resection, a surgeon's major concern is obtaining an appropriate surgical margin. Difficulty or failure to do so can result in prolonged operative time, need for re-operation due to a positive resection margin, or need for complex chest wall reconstruction due to unnecessarily wide resection. Over the last decades, surgical navigation systems have been developed to improve operative precision in various surgical fields. This is achieved by integrating patient images with intraoperative findings. Read Less

The current standard preoperative assessment does not consider the needs of older adults undergoing non-oncological surgery. To enhance the treatment decision-making and planning for older adult surgical patients, the British Geriatric Society and the American Society of Colon and Rectal Surgeons recommend the implementation of preoperative GA for all older adults. Geriatric assessment (GA) predicts treatment toxicity and overall mortality in older adults with complex health problems. However, in-person GA may not be feasible in several clinical settings for various reasons, including lack of training, time, or access to advanced geriatric services. These challenges can be minimized through a self-reported online GA that can be completed by patients prior to the participants' medical appointment. In a previous study, the investigators developed a self-reported online GA, known as the Comprehensive Health Assessment for My Cancer treatment Plan (CHAMP), which was used in geriatric oncology to increase accessibility to GA for older adults with cancer. In this study, the aim is to deploy the CHAMP tool to various clinics across 4 institutions and assess feasibility outcomes, as well as the efficacy of the CHAMP tool in the identification of geriatric issues and the development of supportive care.

This is a pilot trial to assess the feasibility of volume Targeted Ventilation in the Delivery Room. Preterm infants will be randomized to pressure guided or volume targeted ventilation during respiratory support in the delivery room Read Less

Shortness of breath (dyspnea) during exercise is a major source of distress and is a commonly reported symptom in patients with cystic fibrosis (CF). A recent drug treatment option known as Trikafta, which contains elexacaftor, tezacaftor, and ivacaftor, may be used in patients with CF to help improve lung health. However, the effects of this combination therapy on dyspnea and exercise performance, a known predictor of survival in CF, are not clear. The investigators aim to understand the effects of Trikafta on these symptoms and to gain new insight into the potential health improvements in CF from using this treatment option. Read Less

Given the pharmacodynamic and pharmacokinetic properties of glucagon-like peptide-1 (GLP-1) agonists, the Canadian Anesthesiologists' Society has recognized that patients on GLP-1 agonists may have an increased aspiration risk due to a 'full stomach,' even after following preoperative fasting guidelines. In other words, safe fasting timelines are not known in individuals taking GLP-1 agonists, as demonstrated by recent case reports of patients who either retained or regurgitated stomach contents despite being adequately fasted. To address this gap, we plan to measure preoperative residual gastric volumes with point-of-care ultrasound (POCUS) in patients taking this medication. The priority is to first gather data to identify which patient populations need risk stratification and to then use this data to support the development of specific guidelines that reduce anesthetic complications, such as aspiration pneumonia. Our primary objective is to use POCUS preoperatively to assess gastric volumes of fasted patients to demonstrate if there is a clinically significant increase in residual gastric volumes in patients on semaglutide.
