Since the 2019-2020 school year, the province of Quebec (Canada) has been administering one dose of nonavalent (9vHPV) vaccine to students of all genders in Grade 4 of elementary school through the school-based program. Little data on the immunogenicity (antibody production) and long-term efficacy of a single dose of the vaccine are available, particularly in boys. The primary objective of this study is to assess the persistence of HPV antibodies six years after the administration of a single dose of the 9vHPV vaccine to students aged 9 to 11 years in Grade 4 in 2019-2020. The study will be conducted at the CHU de Québec-Université Laval research center. Recruitment is conducted through school service centers in the Quebec City region. Youth who received only a single dose of the 9vHPV vaccine at the ages of 9-11 in 2019-2020 will be eligible to participate. Approximately 300 youth will take part in this study: 150 girls and 150 boys. Participants will have to answer few questions about their health to ensure their eligibility for the study. For eligible participants consenting to participate a 10 ml (\<1 tablespoon) blood sample will be taken.

Over 19Intravenous (IV) ketamine is a treatment option for patients with chronic pain that does not respond to standard therapies, primarily working by blocking NMDA receptors in the brain. Beyond pain relief, ketamine can produce dissociative sensations, classifying it as an atypical psychedelic or mind-altering drug, and may enable patients to reprocess their pain similarly to experiences with traditional psychedelics. At the Montreal General Hospital's pain clinic, the investigators have observed patients frequently listening to music during ketamine infusions, and recent research indicates that music-especially when self-selected by patients-might provide additional pain-relieving benefits by influencing central mechanisms related to pain perception and interpretation. This intersection of music and pain relief is garnering substantial scientific interest as recent advances provide more insight into the neuroscience of music and its effects on brain regions involved in emotion, sensation, memory, and pain. This study aims to investigate the effects of music on chronic pain patients undergoing IV ketamine infusions at the Alan Edwards Pain Management Unit (AEPMU), specifically to determine whether the choice of music affects the intensity and duration of ketamine-induced pain relief. During the infusion (lasting 1 hour), patients will listen to a playlist delivered through specialized headphones, which will either consist of their own selected music (preferred music), music chosen by a music therapist, or no music at all, in a randomized order. Patients will track their pain levels throughout the infusion period and in the intervals between treatments (5 weeks) using standardized pain assessment tools. Additionally, the investigators will assess the subjective experiences of ketamine through interviews and qualitative analysis, while documenting and summarizing any adverse effects. The investigators hypothesize that listening to preferred music will enhance both the intensity and duration of pain relief from IV ketamine. To test this, the investigators will recruit patients already receiving repeated IV ketamine infusions for pain management at the AEPMU clinic. The first infusion will take place under usual conditions to establish a baseline. The infusions will occur in a dedicated room equipped with audio technology to ensure an immersive music experience.

Over 18MTX228 has been identified as a medication that might promote the regeneration of the cells that produce insulin. This 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 their risk of low blood sugars. This open-label dose selection study will test several different doses of tolimidone to see which one works best. The best dose will then be further tested in another study.

18 - 65A closed-loop insulin system, often labelled the "artificial pancreas" (AP), consists of an insulin pump, a continuous glucose monitor, and an interface coordinating between them to regulate insulin dosage based on glucose levels. Primarily designed for managing type 1 diabetes, this system has demonstrated significant benefits in previous studies. Yet, despite these advantages, certain challenges persist. Semaglutide, utilized in treating type 2 diabetes and obesity, is a once-weekly injectable medication that elevates levels of a gastrointestinal hormone known as Glucagon-Like Peptide-1 (GLP-1). This hormone alters gastric emptying, inhibits glucagon release, and reduces appetite. While not officially sanctioned for type 1 diabetes treatment in North America, studies have explored its efficacy as an adjunctive therapy alongside insulin, yielding favorable outcomes in blood glucose regulation. Comparable drugs like liraglutide and exenatide have been employed in type 1 diabetes treatment as well, albeit with less pronounced glucose-regulating effects compared to semaglutide, even in type 2 diabetes. The goal of this 50-week randomized placebo-controlled crossover 2x4 factorial designed trial is to assess whether commercial automated insulin delivery (AID) systems using rapid-acting insulin with adjunct weekly injections of semaglutide (at the maximally tolerated dose) can replace carbohydrate counting with simple meal announcements (SMA) without degrading glucose control.

Over 60In Interstitial Lung Disease (ILD) there is thickening of lung tissue, which makes it difficult for patients to breathe and get enough oxygen into their bodies. In addition to shortness of breath, daily cough is very common, with 4 out of 5 patients experiencing this symptom. Cough in particular has a major impact on the ability to exercise, be active, and to simply enjoy life. There are many reasons for cough in ILD, and very often there are multiple overlapping causes. It is hard to improve cough in these patients, with available medicines providing limited relief. One explanation for this gap is an incomplete understanding of cough in ILD. To improve patients' cough there is a need to better understand its cause. In other lung diseases, such as asthma, doctors and scientists have used phlegm tests to measure inflammation in the lung, which helps them choose the right medicine for the right patient. This has not been done for ILD, even though it has recently been found that many patients with ILD and everyday cough have abnormal phlegm tests. Using this strategy in ILD could improve patients' cough and quality of life, and possibly even slow progression of the disease.

Over 18This study evaluates the use of a lower INR target (1.5 to 2.5) in patients with a mechanical bileaflet heart valve in the aortic position. This study will inform physicians about whether a lower INR target will decrease the risk of bleeding or increase the risk of blood clot formation and stroke. These results have the potential to reduce the burden of bleeding in patients with a mechanical heart valve who require lifelong warfarin (Coumadin) treatment.

Over 18The purpose of this study is to explore the role of a stream of cool air to the face, through fan-to-face therapy, as a novel adjunct non-pharmacological therapy to enable symptomatic adults with cardiopulmonary disease to exercise at higher intensities for longer durations and maximize the psycho-physiological benefits of a supervised exercise training program. The investigators hypothesize that, compared to no fan, fan-to-face therapy will result in relatively greater improvements in exercise endurance time and intensity ratings of perceived breathlessness during constant-load cardiopulmonary exercise testing on a treadmill at 75% of peak power output following a 5-week exercise training period.

Over 40Sexual health is a fundamental aspect of quality of life; a satisfying sexual relationship is linked to better physical, psychological, and relationship health and well-being. In fact, people who maintain a satisfying, active sex life over time live longer than those who report lower sexual frequency and satisfaction. Yet problems with sexual function are extremely common, especially for women: chronic difficulties with sexual desire and/or arousal that are personally upsetting-Sexual Interest/Arousal Disorder (SIAD)-affects 7% to 23% of the general population. SIAD is linked to more healthcare costs, depressive symptoms and anxiety, and lower relationship satisfaction. Experts suggest that relationship factors play a critical role in SIAD and couple-based sex therapy is a common approach used by clinicians. However, there are no treatment options available for couples that have been tested in research to confirm that they work. The goal of this three-centre randomized clinical trial is to evaluate the efficacy of a novel 16-session cognitive-behavioural couple therapy (CBCT), offered online to increase accessibility, for an inclusive sample of women with SIAD compared to a waitlist control group. The investigators expect that, compared to a waitlist control group, CBCT will lead to greater improvements in SIAD symptoms (e.g., higher sexual desire/arousal, lower sexual distress) and better sexual, relational, and psychological adjustment for both partners at post-treatment and 6-months later. Given that less than a third of those affected by SIAD access treatment, this study addresses the urgent need for an accessible couple-based treatment for the most common sexual dysfunction. Results will be used by clinicians to provide couples with a scientifically based, accessible treatment option, that will improve their sexual, relationship, and psychological health.
