One of the most challenging issues in modern medicine is the current opioid epidemic. Given the association between opioid use after surgery and the development of opioid addiction, an essential goal of the medical community should be to develop strategies aimed at instructing the safe use of opioids. In addition, instructions on how to use non-opioid painkillers and exercises and techniques to better cope with pain can be used to reduce the patients opioid requirements after surgery. This study aims to evaluate the effect of providing an online educational video presentation to patients prior to surgery. This will be a 30 minute video which will provide the study participants with instructions on how best to use their opioid and non-opioid medication for pain and also teach the study participants exercises and techniques to better cope with their pain. This intervention will be used with a view to reduce the amount of opioids used by patients following hip or knee replacement surgery. Participants will be followed during their immediate phase after surgery to determine how much pain killers the participants have used and at six weeks the participants will be asked to return their unused opioids to see how much the participants have used in total.

The purpose of this study is to investigate whether the gut bacteria in IBD patients cause ongoing abdominal pain, even when the disease is calm. Many inflammatory bowel disease (IBD) patients have this pain, regardless of whether their disease is active or not. This might be linked to an imbalance in gut bacteria. Certain IBD patients with persistent abdominal pain experience increased sensitivity in their gut due to bacteria producing LPC and LPA. Our goal is to explore the connection between bacterial LPC/LPA levels and symptoms in IBD patients with long-lasting abdominal pain. Additionally, we aim to pinpoint the specific bacteria responsible for producing LPC/LPA, which in turn causes chronic abdominal pain in these patients.

The purpose of this clinical trial is to evaluate the impact of an online group intervention called Healthy Minds in facilitating a sustainable return to work for individuals with a mood disorder. The study aims to answer the following key questions : * Does receiving the Healthy Minds online intervention lead to a more sustainable return to work compared to not receiving the intervention? * Are the health outcomes (e.g., depressive symptoms) and work-related outcomes (e.g., work functioning) of individuals who receive the Healthy Minds online intervention better than those who do not receive the intervention in the year following the intervention? Both experimental and control participants will be recruited at baseline while on sick leave (expected to return to work in less than one month) or recently returned to work (less than one month). Participants will complete a series of online questionnaires at the following time points : * Baseline * First follow-up (2 months after baseline) * Second follow-up (6 months after baseline) * Third follow-up (12 months after baseline) The questionnaires will cover the following areas : * Sociodemographic and biopsychosocial factors * Symptoms associated with the primary mood disorder * Cognitive difficulties and biaises * Self-efficacy related to return to work * Work accommodations and natural supports * Relationship with immediate supervisor * Work functioning * Return to work time (number of days away from work) Experimental participants will participate in the 2-month online Healthy Minds group intervention (cohort of 5 participants) between the baseline assessment and the first follow-up. The intervention consists of 8 sessions (one per week for 8 weeks), with each session focusing on a specific aspect of the return-to-work process from a cognitive-behavioral perspective.

This is a randomized double-blind placebo controlled trial involving a single centre (McMaster University) recruiting patients from Hamilton, ON and the surrounding regions, to evaluate whether fecal microbiota transplantation once weekly for six weeks increases the remission rate compared to placebo in patients with active pouchitis.

The rationale for the study is to obtain safety and efficacy data as well as to establish dose parameters for the SpectraCure P18 System with IDOSE®, with verteporfin for injection (VFI) as photosensitizer for the treatment of recurrent prostate cancer.

One in five Canadians live with chronic pain, defined as pain that lasts longer than 3-months. Living with chronic pain has a detrimental impact on physical health, emotional health, and quality of life. Current treatments rarely result in pain relief and often do not meaningfully improve physical or emotional function. Further, medication used to treat pain often causes unwanted symptoms. There is a need to develop new treatments to help manage chronic pain. The use of a nasal spray containing manufactured oxytocin may improve pain management. Oxytocin is produced in the human body and has been shown to impact the pain pathway in animals. Our project tests whether the use of a nasal spray containing oxytocin will improve pain and function in men and women who live with chronic pain. Men and women with chronic nerve, muscle, or pelvic pain will be recruited in Vancouver, Calgary, and St. John's. Each person will be assigned to complete three interventions in a random order. Each intervention involves using a nasal spray twice per day over a 2-week period. The nasal spray will contain a small dose of oxytocin during one intervention and a medium dose during the second intervention. The nasal spray during the final intervention will have no oxytocin. This final intervention is a control intervention that will allow us to measure the effect of simply taking a nasal spray (i.e., the impact of expectation). Participants and researchers will not know which interventions involve the use of oxytocin. Participants will rate their pain and function each day throughout each task. The investigators will calculate each person's score on pain and function. The investigators will test whether participants report less pain and better function when they use oxytocin compared to the control. The results of this project may improve pain, function, and quality of life among those who live with chronic pain.

This exploratory study aims to verify the hydrating potential as well as the possible irritant effects of a 14-day hydrating treatment consisting of daily application of serum and cream to the skin of two dry targeted areas. Thirty-three (33) subjects will be enrolled in this study and will be divided into three different treatment groups of 11 subjects each. Apart from the formulation of the cream which varies between the three groups, the subjects will receive the same serum and adhere to the same study plan for fourteen days. Each subject's baseline condition before treatment will serve as a control for effects observed after treatment on targeted areas.

This is a prospective, single-arm, single-site study designed to generate data describing the image quality and applicability/useability of a high-performance, on-couch CBCT imaging technology (HyperSight) in patients receiving radiation treatment for cancer on a C-arm linear accelerator (TrueBeam).

Despite major technological advances in type 1 diabetes (artificial pancreas), the management of hypoglycemia remains a major challenge, especially during and after physical activity. The primary outcome is to determine the temporary blood glucose (BG) target to be set 60 minutes before aerobic exercise in people with type 1 diabetes (PWT1D) using do-it-yourself automated insulin delivery (DIY-AID) systems. Three glycemic thresholds to be applied 60 minutes before physical activity will be tested in 32 people on AID-DIY: 8.3 (current target for commercial AID systems), 8.8, and 9.3 mmol/L. Each participant will perform 3 sessions of moderate aerobic physical activity (ergocycle) at 60% of vo2peak with a different glycemic target each time (random order). Plasma glucose will be measured every 20 minutes before and during physical activity, and blood glucose measured by continuous glucose reading (DEXCOM) for 24 hours post-intervention. Once the best glycemic target is selected, participants could come to the research center for 1 or 2 more voluntary interventions to test the threshold during 1) fasting exercise and 2) late luteal phase of the menstrual cycle.

The guided FNA by endobronchial ultrasound ( Endobronchial Ultrasound guided transbronchial Needle Aspiration or EBUS-TBNA) is a minimally invasive technique with an established role in the staging of lung cancer 1, and in the evaluation of intrathoracic lymph node metastases from extrathoracic primary cancer2 . There is also a role in cases of isolated hilar and mediastinal lymph nodes in which the differential diagnosis includes mostly sarcoidosis, lymphoma and tuberculosis. 3 Various studies have evaluated more recently the diagnostic yield of EBUS-TBNA specifically for sarcoidosis 4 and thoracic lymphoma 5-6. Although there is emerging data supporting the usefulness of EBUS-TBNA in the investigation of these two pathologies, the efficacy results vary according to the target populations and certain parameters. Moreover, although a large randomized study demonstrated e superiority of EBUS-TBNA over conventional bronchoscopic sampling methods \[ bronchoalveolar lavage (BAL) and trans-bronchial biopsies (TBB \] for the diagnosis of sarcoidosis , 7 the results suggest that there is still room for optimizing the performance of EBUS-TBNA \[b\] . In the field of lymphoma, obtaining large enough specimens for adequate subtyping also remains a concern. 8 In order to improve the performance of EBUS -TBNA , new needles have been developed with the aim to provide biopsies for histological evaluation rather than purely cytological. The ViziShot FLEX © (Olympus) 19 gauge needle (19 gauge or 19G) is a large needle, which can provide both tissue and needle aspiration , and has the advantage of being more flexible. For this study, the investigators want to compare the diagnostic yield of EBUS-TBNA using needle ViziShot FLEX 19G (1.11 mm) with that of the standard 22G needle ( NA-201SX; Olympus) , in the investigation of hilar or mediastinal lymphadenopathy suspected to be sarcoidosis or lymphoma.
