Consuming dietary protein stimulates whole-body and muscle protein synthesis, the latter of which is typically measured using invasive primed constant infusions of stable isotopes with concurrent muscle biopsies. Alternative non-invasive methodologies have been developed (namely the indicator amino acid oxidation (IAAO) technique) to estimate the impact of protein ingestion on whole-body protein synthesis as a proxy for determining dietary protein requirements. Given that the IAAO technique is based on principles of protein metabolism which occur in the liver, it is unclear how representative the IAAO outcomes of whole-body protein synthesis is to skeletal muscle protein synthesis. Validation of the IAAO technique against gold-standard, biopsy-derived measures of muscle metabolism (i.e., muscle protein synthesis) would assist in mitigating the invasiveness of muscle physiology and nutrition research.

Evaluate the performance and safety of the GT Metabolic Magnet System for the creation of side-to-side compression anastomosis in the stomach and/or small bowel in conditions requiring an anastomosis as part of the underlying clinical treatment.

The inhalation of adenosine 5'-triphosphate (ATP) to evoke cough (ATP cough challenge) is becoming increasingly used as a tool to measure cough hypersensitivity in patients with chronic cough. However, the safety, feasibility, and repeatability of this procedure is not widely known. In this study, we will perform ATP cough challenges in healthy individuals and in patients with mild asthma and chronic cough to better understand the safety, feasibility, and repeatability of these challenges. Such information will guide the future conduct of ATP cough challenges to measure cough hypersensitivity and identify patients who may better respond to ATP-blocking therapies.

This study aims to examine the clinical profile/anatomical characteristics and natural history of patients who subsequently fail screening for transcatheter mitral valve intervention (TMVI).

Study consists of two main parts to explore BGB-16673 recommended dosing, a Phase 1 monotherapy dose finding comprised of monotherapy dose escalation and monotherapy safety expansion of selected doses, and a Phase 2 (expansion cohorts)

Rates of obesity in patients with schizophrenia-spectrum disorder (SSD)s have reached epidemic proportions, with established contributing effects of antipsychotic (AP) medications. Among agents approved for chronic weight management, glucagon-like peptide-1 receptor agonists (GLP-1RA) are associated with reductions in cardiovascular mortality, with recent FDA approval for once weekly semaglutide for this indication. This study will investigate whether semaglutide is effective in reducing body weight in overweight or obese individuals with SSDs who are on APs and do not demonstrate adequate weight loss on metformin (the first line treatment for weight loss in SSDs).

This is a prospective, open-label, multi-center, single-arm (non-randomized) study to assess the safety and effectiveness of breaking stones in the upper urinary tract using the SonoMotion Break Wave technology. Up to 30 subjects will be included. The procedure will be performed in a hospital surgical environment as an outpatient (without being admitted) or in a non-surgical environment such as a clinic or office procedure room. The procedure will be performed under varying levels of anesthesia ranging from no anesthesia to general anesthesia (fully asleep). Stones will be limited to ≤ 10 mm for lower pole stones and ≤ 20 mm everywhere else. Safety will be measured by the self-reported occurrences of adverse events, unplanned emergency department or clinic visits, and the need for further intervention. Fragmentation will be measured by self-reported stone passage and a comparison of computed tomography (CT) images before and after the procedure.

The purpose of this research is to determine the effect of additional daily egg intake on metabolic phenotypes and metabolism in the context of obesity.

Despite the availability of medications, many people around the world continue to live with long-term health problems like heart disease, stroke and diabetes. In Canada, heart disease is a leading cause of death. Managing these health issues can be done by changing diet and lifestyle. Specific ways of eating have been proven to improve risk for heart disease and stroke. However, because doctors often have limited time, nutrition education, and lack of tools for counseling patients on nutrition, they can often only provide minimal support to help patients make necessary lifestyle changes. Digital tools and mobile applications offer an opportunity to involve doctors and patients in delivering nutrition interventions. This approach has the potential to save time, provide education, and reduce healthcare costs. This study is being done to understand the effect of a digital heart health program added to standard of care, compared with standard of care alone on heart health. All eligible participants in this study will be randomized (determined by chance) to one of two possible interventions: 1) a digital heart health program + standard of care; 2) standard of care. Standard is care is defined as the best practice based on guidelines for the treatment of a condition. All participants will be followed for seven years and will be asked to complete online questionnaires and complete blood work at their nearest LifeLabs clinic, as well as wear a continuous glucose monitor and wrist actigraph (at 3 time points in the first year). In addition, participants randomized to the digital heart health program + standard of care will be expected to use the heart health app and join 16 online synchronous sessions over the first year. After seven years, the intervention phase of the study will end and the study will become a cohort study. All participants at the 7-year time point will be invited to use the heart health app. As part of the cohort study, participants will be asked to continue completing the same questionnaires online and completing bloodwork at their nearest LifeLabs every four years for the duration of their participation in the cohort study. The main questions this study aims to answer are: 1. Will a digital heart health program added to standard of care result in a clinically meaningful reduction in blood cholesterol and other risk factors after 1-year compared to standard of care alone? 2. Will a digital heart health program added to standard of care result in a reduction in major cardiovascular events after 7-years compared to standard of care alone? 3. Are the observed effects sustained beyond the 7-years of the intervention? We hypothesize that the digital heart health program added to standard of care will result in a clinically meaningful reduction in blood cholesterol and other risk factors for heart disease after 1-year and reduce major cardiovascular events after 7-years compared to standard of care alone.

This project aims to monitor the innocuity/safety profile of cyclotron-produced \[68Ga\]-PSMA-617 PET imaging in PSMA-expressing cancers. It is a single-site, pragmatic, non-randomized and open-label study, with no control group. Although prostate cancers constitute the usual recommended population for this PET modality, recent evidences suggest that most solid tumors express substantial amount of PSMA in their neovasculature. As such, all cancers (excluding non-solid cancers) will be eligible for \[68Ga\]-PSMA-617 PET imaging in this trial, for as long as their tumors express PSMA. This study also aims to instigate the use of \[68Ga\]-PSMA-617 in the routine standard-of-care for detection and follow-up of eligible cancers. FInally, this project seeks to gather information about the impact on patient management this novel PET modality will have over the current standard-of-care.
