The study involves characterizing the microbiota of patients with IBS, functional diarrhea, IBD, severe motility disorders and celiac disease. This will be complemented by a translational phase of human-mouse hybrid experiments in which germ-free mice will be colonized with feces from these patients with different GI disease and non-disease controls and we will compare symptoms, microbiota composition and histological changes in the gut and in the brain of the mice.

In Canada, 1,700,000 adults are at risk of dementia, half of them with MCI,representing one of the largest groups at risk for an incurable disease. Epidemiological evidence suggests up to 40% of dementia cases might be preventable by targeting modifiable lifestyle and cardiovascular factors. Given that current treatments cannot modify the disease, prevention is critical. SYNERGIC-2 offers a "personalized multidomain intervention" that combines physical and cognitive training, sleep, diet, and vascular-metabolic interventions in individuals with MCI to synergistically enhance their overall brain health including cognition and contributes to maintaining their independence. Importantly, interventions will be provided at home using an existing virtual platform reducing delivery complexity and expanding the accessibility to a wider population, thus decreasing potential inequities. Improving older adults' brain health and achieving even a modest two-year dementia incidence delay will have a projected saving of $218 Billion in Canada's healthcare system over 30 years.

Pain is one of the most common symptoms of extreme stress in youth. Without treatment, short-term pain can last for months to years (called 'chronic pain'; CP), a problem already affecting 1 in 5 Canadian youth. The COVID-19 pandemic is one of the greatest threats to youth mental health seen in generations. CP in childhood can trigger a wave of mental health issues that last well into adulthood. In 2019, we learned that "access to pain care" is poor and a priority for youth with CP and their families. Unfortunately, COVID-19 has only made access more difficult. In 2020, we created an online "stepped care" program called the Power over Pain Portal for youth with CP. Stepped care is a promising way to improve access to CP care by tailoring care based on the symptoms each youth is experiencing. Like a ladder, youth start with one type of care and then "step up" or "step down" to more or less intense care depending on what they need. Over the past year, funded by CIHR, we worked with hundreds of youth and healthcare professionals across Canada to understand how the pandemic has affected pain and mental health. We also summarized all online pain self-management programs including peer support for youth to find the best resources to include in the Portal and will translate the portal content into French. Together with a diverse group of youth with CP, we have now co-designed the online Portal. The next step (focus of this grant) is to test the Portal with youth to ensure it can be implemented and is helpful. We will recruit 93 youth with CP waiting for specialist care at 11 CP clinics across Canada to use the Portal for 4 months. We will see how they use the Portal and if it helps to improve their pain and mental health. This study is important because it will allow us to understand how the Portal works in the real world before wide public release (English and French) to support all youth in Canada with CP with accessible, evidence-based pain care.

The goal of this interventional study is to evaluate the effect of three different designs of trunk assistance exoskeletons on cumulative lumbar load, trunk extensors' muscular fatigue and comfort in healthy volunteers. The main questions it aims to answer is: will exoskeletons reduce muscle fatigue and cumulative lumbar load. Participants will : * get each exoskeletons adjusted and then practice the lifting task and measurement sequence in a first session * perform a lifting task for 4 blocks of 20 minutes on different sessions for each exoskeleton, another session is performed without assistance.

Our objective in this study is to identify an optimal ultrasound spectroscopy parameter that can be used as an early predictor of pathological complete or partial response in men with prostate cancer and men and women with rectum and head and neck cancers receiving treatment radiotherapy. We have previously demonstrated that high-frequency ultrasound and spectroscopy, and recently conventional-frequency ultrasound and spectroscopy may be used to detect cell death in vitro, in situ and in vivo. The method can detect different forms of cell death and has been demonstrated to be sensitive to apoptotic, necrotic and mitotic cell death. The main goal, as described above, is to select the best ultrasound spectroscopy parameter to use as an early predictor of pathological complete response

The ultimate aim of this study is to identify a biomarker of suicide risk in MDD by measuring the "hedonic spectrum" (pain and reward responsivity), attention and its associated brain structures using brain scans (fMRI and DTI), as well as the stability of markers over time.

This study will be conducted in 2 parts. The first part is a phase 1 single-agent dose escalation, and dose optimization, study of tegavivint in patients with advanced HCC after failure of at least one line of prior systemic therapy. The second part of the study will begin with a brief dose escalation part for each combination (tegavivint plus cabozantinib or tegavivint plus lenvatinib) followed by a combination dose expansion.

This study is being conducted to learn more about a procedure, balloon dilation of the eustachian tube, in treating patients with eustachian tube dysfunction. Traditionally, eustachian tube dysfunction is treated with nasal steroid sprays and decongestants, or by placement of ear tubes. However, current evidence suggest that medical options are ineffective, and placement of ear tubes is not risk-free. Therefore, we are carrying out this research study to determine if balloon dilation of the eustachian tube is superior to a sham procedure in treating patients with eustachian tube dysfunction.

There is growing evidence for the effectiveness of internet-delivered cognitive behaviour therapy (ICBT) for post-secondary students with symptoms of depression and anxiety. In ICBT, clients review structured online content over several weeks to learn strategies and skills to manage their symptoms. Low treatment completion rates remain a concern for post-secondary students, so it is possible that existing treatment protocols do not offer enough flexibility for students' needs and preferences. This trial will examine students' preferences for different course options (fast-track, 5-week, and 8-week) and compare enrollment, adherence, and outcomes of students who pick each of the three options. In all three options, students will receive optional therapist support, in which the assigned therapist only contacts the student on weeks where the student sends the therapist a message. This trial will help inform the delivery of flexible treatment options for post-secondary students in a routine care setting.

The goal of this observational study is to collect health data on people who are at high risk of having heart complications and are having a surgery that is not on the heart. The main questions it aims to answer are: * Is this study feasible in terms of recruiting enough people to participate in this study? * How often do heart complications happen in people who are at high risk of heart complications and are having a surgery that is not on the heart? Participants will have their usual care and will also be asked to: * Have extra bloodwork done * Complete some surveys * Have two echocardiograms (ultrasounds of the heart) * Continue to follow-up with the research team for one year after their surgery Researchers will compare how often heart complications occur in this high risk population to a future study where participants will receive stem cells before their surgery.
