Favorable-risk prostate cancer represent a large proportion of patients diagnosed with prostate cancer and image guided radiation therapy (IGRT) is commonly used to treat these patients using protracted courses of up to 39 treatments over 8 weeks. Stereotactic ablative body radiotherapy (SABR) protocols hold the promise of more convenience, less side effects, less cost and improved system capacity without sacrificing excellent cancer control rates. By the same token, prostate high-dose rate (HDR) brachytherapy boost has been shown to be superior to standard external beam radiation. While two HDR fractions appear to optimize patient convenience and outcomes while minimizing costs, we wanted to determine the tolerability of combining one MR-guided HDR treatment with one SABR treatment to further reduce HDR resource use while maintaining favourable treatment outcomes.

The goal of this intervention study is to test the effects of a nurse-led mobility intervention (known as the OASIS Walking Intervention (Older Adults performing Sit to Stands and Walking Intervention)) in older adults with cognitive impairment, such as dementia, in transitional care programs. The main questions this study aims to answer are: * Is the study doable and are older adults satisfied with the intervention? * Does the intervention improve older adults' muscle strength, mobility, functional status and quality of life? Participants will be asked to do the following: 1. Be interviewed once so that a patient-centred communication care plan can be made 2. Do sit to stand activity 3. Walk as part of a walking program.

Type 1 diabetes is an autoimmune disease where the body attacks the insulin-producing cells in the pancreas. In the absence of insulin, the body is unable to effectively use glucose for energy, resulting in high blood sugar levels. This leads to a lifelong need for intensive insulin therapy to manage blood sugar and prevent complications arising from elevated blood glucose levels. When insulin is low, the body produces ketone bodies. If ketone levels rise too high, they can lead to the dangerous condition known as diabetic ketoacidosis. Diabetic ketoacidosis remains a leading cause of mortality in children and young adults with type 1 diabetes. Sodium/glucose cotransporter 2 inhibitors, such as empagliflozin, are effective in lowering blood sugar but can also increase ketone levels, raising the risk of diabetic ketoacidosis. Empagliflozin is approved for type 2 diabetes and has demonstrated benefits in type 1 diabetes, including improved blood sugar control at lower doses and reduced risks of chronic kidney disease and mortality at higher doses. However, its use in type 1 diabetes is still off-label due to the heightened risk of diabetic ketoacidosis. Using empagliflozin at a commercial dose safely is desirable to maximize its potential renal benefits in type 1 diabetes. While there are measures to monitor ketone levels, current methods, such as finger prick tests, often detect issues too late to prevent diabetic ketoacidosis. Continuous ketone monitoring offers real-time tracking of ketone levels, which could enable timely interventions to maintain safe levels. Moreover, there is currently no data on continuous ketone metrics in individuals with type 1 diabetes using sodium/glucose cotransporter 2 inhibitors. We aim to understand the dynamics of ketone levels in people with type 1 diabetes using empagliflozin, including in challenging situations such as during exercise and low-carbohydrate diets while on sodium/glucose cotransporter 2 inhibitors. To this end, we will conduct an open- label, single-arm, outpatient study where 24 participants with type 1 diabetes will use continuous ketone monitoring for a 4-week run-in, followed by empagliflozin 2.5 mg for four weeks and then empagliflozin 10 mg for nine weeks. Participants will perform an exercise sub-study during the fourth week of the continuous ketone monitoring run-in and during the eighth week of empagliflozin 10 mg use. Certain participants will be invited to undergo a low-carbohydrate diet during the last week of empagliflozin 10 mg use. The results, if positive, may lead to i) novel long-term (6 months) data on ketone levels in those with type 1 diabetes using empagliflozin, including individuals on multiple daily injections and closed-loop therapy across a wide range of body mass index, ii) data on the relationship between empagliflozin, exercise, low-carbohydrate diets, and type 1 diabetes, and iii) the creation of important metrics for ketone thresholds that have not yet been characterized. Furthermore, we hope this preliminary study will inform future research to investigate the use of continuous ketone monitoring to allow for the safe use of higher doses of sodium/glucose cotransporter 2 inhibitors in people with type 1 diabetes.

This First-in-Human (FIH) Phase 1/2 study is designed to characterize the safety, tolerability, and pharmacological activity (as assessed by biomarker measurements) and to determine the optimal dose of mRNA-3927 in participants with genetically confirmed propionic acidemia (PA). After establishing a dose with acceptable safety and pharmacodynamic (PD) response in a Dose Optimization Group (Part 1) in participants ≥1 year of age, additional participants will be enrolled into the study in a Dose Expansion Group (Part 2) to allow for further characterization of the efficacy, safety, and PD of mRNA-3927. Part 3 will evaluate the safety, efficacy and PD response of mRNA-3927 in infants (\<1 year of age).

The objective of this study is to determine whether VR can ameliorate symptoms for palliative care patients within a hospice setting. We also aim to verify the efficacy with a larger sample size than previously shown, as well as extend the population to include non-cancer patients receiving Hospice care. We will further attempt to delineate whether there is a sustainability of symptomatic improvement one week after VR experiences.

Our research group has found that Canadians with undiagnosed asthma or chronic obstructive pulmonary disease (COPD) have increased respiratory symptoms and worse health-related quality of life. The investigators recently developed and validated an on-line questionnaire to accurately identify these symptomatic, undiagnosed individuals. The investigators will advertise in the community asking individuals to complete the on-line questionnaire at home, at their leisure, to determine if they are at risk of asthma or COPD. Those at risk will be invited to participate in a randomized, controlled clinical trial to determine whether early diagnosis of previously undiagnosed asthma or COPD and subsequent treatment by the primary care practitioner will improve their quality of life.

Endurance exercise performance declines in hot environments as core body temperature increases. To enhance performance, body pre-cooling strategies, such as cold-water immersion have been employed to lower resting core temperature thereby increasing the body's heat storage capacity. In turn, the increase in body core temperature associated with exercise in the heat is blunted, allowing the individual to exercise at higher intensity and or for a longer period of time. However, the mechanisms by which pre-cooling impacts heat exchange during exercise remain unclear. While existing research has focused on the performance benefits of pre-cooling the body, relatively little is known about the impacts of pre-cooling on whole-body heat exchange during an exercise-heat stress. Investigators will therefore evaluate whole-body heat exchange (dry ± evaporative heat loss as assessed using a direct air calorimeter) during a prolonged (1-hour) moderate-intensity cycling bout in the heat (wet-bulb globe temperature of 29°C; equivalent to 37.5°C, 35% relative humidity) performed with and without pre-cooling by cool-water (\~17°C) immersion.
