MTX228 has been identified as a medication that might allow the re-growth of insulin producing beta cells in people with Type 1 Diabetes. Promoting the re-growth of lost beta cells would be beneficial to people with Type 1 Diabetes because it would allow them to take less insulin by injection and would improve their overall blood sugar control while reducing the risk and rate of low blood sugars. This open-label dose selection study aims to determine the optimal dose ofMTX228 for use in a future phase IIb study. The purpose is to investigate the relative effectiveness of different doses of MTX228 and to select the most effective dose for further investigation in a phase 2b study. Read Less

Infants born preterm can spend months in the neonatal intensive care unit (NICU) where they experience stressful but essential procedures. Untreated stress is associated with altered brain development. Skin-to-skin care (SSC) is one of the most effective behavioral strategies for mitigating preterm infant stress and improving brain maturation. However, parents may not be always available to provide SSC; some infants cannot be held for long periods for medical reasons. To address this problem, investigators designed Calmer, a patented, prototype therapy bed, for reducing stress in preterm infants. Calmer fits into NICU incubators and provides simultaneously an artificial skin surface, heartbeat sounds and breathing motion, mimicking aspects of SSC; the latter 2 features are individualized for each infant based on their parents' recordings. The 1st randomized controlled trial (RCT) in 58 preterm babies showed that during a routine blood test: Calmer lowered infant behavioral and heart stress responses and stabilized brain blood flow no differently than facilitated tucking; infants could be cared for safely on Calmer up to 6 hours in 1 day; Calmer was well accepted by mothers and staff. The goal now is to determine the efficacy of Calmer use over 3 weeks to support optimal physical growth and brain development in preterm infants. A 2-group (treatment, control) pilot RCT to test the implementation of an increased "dose" of Calmer exposure over 2-3 continuous weeks is proposed. 30 infants born between 26-30 weeks gestational age in the NICU will be randomized to receive either Calmer, for a minimum of 3 hours in total/day for 2-3 continuous weeks, or to 2-3 weeks of standard NICU care (minimum of 2 and maximum of 3 weeks). Research questions: Trial feasibility Q1. Is it feasible to enrol 30 infants, complete a 2-3-week treatment period (minimum of 2 and maximum of 3 weeks), and measure growth outcomes in preterm infants (26-30 weeks GA) in the NICU in a pilot RCT of daily Calmer treatment versus standard NICU care to inform a larger, definitive RCT? Infant outcomes Q2a. Are there differences in physical growth markers (daily weight gain, head circumference, body length) between preterm infants who receive Calmer and those who receive standard NICU care measured before (baseline) and after 2-3 weeks of daily Calmer exposure? Q2b. Are there differences in brain activity markers, as measured by cerebral electrical (EEG) signalling, between preterm infants who receive Calmer and those who receive standard NICU care, measured during a resting/sleeping state and routine diaper change session at the end of the trial (post 2-3 weeks of daily Calmer exposure)?

Physical activity and dairy consumption during growth and development are each known to improve peak bone mass in young adults. Peak bone mass, the maximum amount of bone a person will have in their lifetime, is typically reached in the early 20's in females and late 20's in males. However, evidence suggests that young people do not consume enough dairy to maximize their bone mass. The resulting effect in peak bone mass can be troublesome, particularly for athletes, such as volleyball players. This study aims to determine whether increased dairy consumption combined with training can have an additive effect on the physiology of young competitive athletes. Specifically, we will examine whether Greek yogurt consumption will lead to beneficial changes in bone metabolism and inflammation, in adolescent and young adult, male and female athletes, similar to those observed with whey protein supplementation. Many athletes choose exclusively protein supplementation and miss out on other nutrients vital for healthy growth and development. By examining the benefits of Greek yogurt across different athlete age groups and sexes, this work will help reshape the attitudes, beliefs, and behaviours surrounding diet of young athletes.

The clinic visits (intervention) will continue for 90 days, which represents the follow-up period for the primary medication and health status outcomes. The co-primary clinical outcomes will be obtained at 180 days. Read Less

Patients with ovarian cancer with defective DNA repair mechanisms derive substantial benefit from PARP inhibitor (PARPi) maintenance therapy. Both niraparib and olaparib are effective inhibitors of PARP, which exploit already defective DNA repair mechanisms (e.g., via BRCA mutations), particularly those with homologous recombination deficiency (HRD). These two PARPis have notably different toxicity profiles, with niraparib showing many more severe side effects. In this Ovarian Cancer Canada funded study, we will implement perform HRD testing for ovarian cancer patients in Saskatchewan with response to platinum-based chemotherapy. This information will provide personalized and precision estimates about the amount of benefit that can be expected from taking a PARPi. We will evaluate both treatment outcomes and quality of life in a real-world study setting, to inform future decision-making regarding efficacy, quality of life and cost-effectiveness of PARPi therapy, specifically for niraparib. We hypothesize that for patients who are homologous recombinant proficient (HRP), the median 32.7-month incremental benefit (in delaying cancer progression) from taking a PARPi (niraparib is the only PARPi approved in this setting) will not be seen as being value-add when balanced by the decreased quality of life that accompanies the first 6-12 weeks of therapy. We also hypothesize that for women who are HRP, that PARPi therapy will not be cost-efficient. Read Less

The standard or usual workup for cognitive impairment, including Alzheimer's Disease, may include brain amyloid PET with PET/CT or PET/MR imaging. Amyloid PET is the standard imaging that was requested for you by your referring physician. This imaging can visualize your brain. With the development of new therapies for Alzheimer's disease which require amyloid PET imaging, there will be a significant increase in the number of PET scans needed to provide care to all patients. There are likely not enough PET scanners in Canada to meet this demand. Therefore, we are searching for comparable alternatives. One of the imaging devices that was introduced in the clinic is the Radialis PET imager (or RPI). Health Canada, the regulatory body that oversees the use of devices in Canada, has not approved the sale or use of the Radialis PET imager. Health Canada has allowed the Radialis PET imager to be used in this study. We would like to see whether the images obtained for the brain are comparable to those obtained from a PET/CT or PET/MRI scanner. It is a new type of PET imaging device for patients undergoing a PET scan and has been used in Canada for research. RPI is experimental, meaning that this PET scan is not used routinely in patients' care. In comparison to the standard PET devices, RPI is smaller and mobile, meaning it can be moved around easily for use. Also, it can be installed in imaging centers at a lower cost. These advantages make RPI an interesting alternative to the standard PET. However, the performance of this new imaging device has not been tested in Amyloid PET imaging in particular. As you may know, in a PET scan, we inject a radioactive material (called tracer) which can circulate in your body and visualize specific areas in your body. In amyloid PET we inject an amyloid tracer that goes to the brain and lights up certain regions of the brain. RPI was previously tested for other PET tracers and was shown to be comparable to standard PET devices. Thus, by changing the PET material (to Amyloid), we are pursuing the same aim: comparison of RPI with standard PET devices and see whether it can provide comparable images of the brain. Read Less

The goal of this randomized controlled trial is to compare the short-term effects of a virtual, community-based, task-oriented group exercise program (TIME™ at Home) with a waitlist control in community-dwelling adults with balance and mobility limitations. The main questions the trial aims to answer are: 1. Will there be improvements in physical and mental health outcomes, and caregiver mood and assistance, following participation in the TIME™ at Home exercise program that are greater than in the waitlist control group? 2. Will level of mobility limitation, sex, or gender influence the experiences of people in the exercise program? 3. What will be the costs of the TIME™ at Home exercise program for the organization delivering the program, and the people who are in the exercise program? Participants and their caregivers will be asked to complete 3 evaluations using Zoom at study entry and 2 and 5 months later. * Participants will complete tests of balance and walking and questionnaires. * Caregivers will only complete questionnaires. After the first evaluation, participants will be randomly assigned to either participate in: * the 8-week TIME™ at Home exercise program from their homes using Zoom, or * to wait 5 months (waitlist control group) before beginning the 8-week TIME™ at Home exercise program Read Less

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.
