Little evidence exists to guide treatment in patients with massive irreparable rotator cuff tears (MRCTS). Arthroscopic partial rotator cuff repair (PRCR) has the longest record of use. The new technique of superior capsular reconstruction (SCR) has more recently been described. Despite high enthusiasm for this technique, its effectiveness, cost and safety profile have not been established. The long-term goal of this study is to perform a multicenter randomized control trial to evaluate the effectiveness of SCR compared to PRCR in patients with MRCTS. The current study is a pilot required to support the development of an expanded formal clinical trial.

The goal of this Prospective single-blinded intervention feasibility study is the utilization of the AIRE-2 device and FoodMarble app to elucidate the interplay among diet, symptoms, and microbial fermentable features in IBD patients with persistent intestinal symptoms and their household controls. AIRE-2 captures exhaled hydrogen and methane and FoodMarble app records breath levels, symptoms and dietary intake. The main questions it aims to answer are: 1. To assess the feasibility of using the AIRE-2 device, FoodMarble mobile app in a cohort of IBD patients and their household controls to collect data on diet, symptoms and exhaled H2 and CH4 levels. 2. 2. To assess the feasibility of using FoodMarble's FODMAP discovery kit protocol in a cohort of IBD patients and their household controls. 3. To collect preliminary data on the relation between diet, symptoms, and exhaled H2 and CH4 levels measured by the AIRE-2 device and FoodMarble app in a cohort of IBD patients and their household controls. 4. To explore the correlation between the fecal microbiome sequencing profile with exhaled H2 and CH4 levels, diet and symptoms in a cohort of IBD patients and their household controls. You will: 1. Record regular diet in the FoodMarble app and collect baseline stool samples 2. You will then take a low FODMAP diet for 24 hours every week and record the diet and symptoms. After the diet, you will take the FODMAP challenge of Lactose, Fructose, Sorbitol and Inulin (one every week) using Sachets provided by FoodMarble company, record exhaled breath levels, symptoms and collect stool. This process will take 4 weeks. 3. Visit clinic to submit stool samples

Allogeneic Haemopoietic Stem Cell Transplant (Allo-HSCT) is a potentially curative option for patients with both malignant and non-malignant hematological disorders. There appears to be unique experiences that adolescents and young adults (AYA) face when undergoing transplant. There is literature to suggest that peer support for young adults is associated with improvements in mental health including greater happiness, self-esteem and effective coping, as well as reductions in depression, loneliness and anxiety. Our primary objective is to determine the feasibility and acceptability of an AYA peer support program for patients undergoing Allo-HSCT. Our secondary objective is to explore the impact of the AYA peer support program on sense of support/connectivity, anxiety, and depression.

The purpose of the study is to evaluate the long-term safety and effectiveness of cochlear implantation of the approved population in adults and children with single-sided deafness and asymmetric hearing loss.

The purpose of this study is to learn about the safety and effects of the study medicine called vepdegestrant. The safety and effects of vepdegestrant will be see when given with other medicines. Vepdegestrant is studied to see if it can be a possible treatment for advanced metastatic breast cancer. This type of cancer would have spread from where it started (breast) to other parts of the body and would be tough to treat. The study is seeking for participants who have breast cancer that: * is hard to treat (advanced) and may have spread to other organs (metastatic). is sensitive to hormonal therapy (it is called estrogen receptor positive). * is no longer responding to treatments taken before starting this study. This study is divided into separate sub-studies. For Sub-Study C: All the participants will receive vepdegestrant and a medicine called samuraciclib. Vepdegestrant and samuraciclib will be taken once in a day by mouth. The medicines will be taken at home. The experience of people receiving the study medicines will be studied. This will help see if the study medicine is safe and effective. Participant will continue to take vepdegestrant and samuraciclib until: * their cancer is no longer responding, or * side effects become too severe. They will have visits at the study clinic about every 4 weeks.

The primary purpose of the study is to evaluate the antitumor activity and safety of novel immunotherapy combinations compared with dostarlimab in participants with Programmed death ligand 1 (PD-L1) positive Recurrent/Metastatic (R/M) Head and Neck Squamous Cell Carcinoma (HNSCC).

The purpose of this study is to evaluate quantitatively and qualitatively a mobile application, Joint Effort, targeting safe cannabis use among consumers. This randomized controlled trial is currently conducted on the Joint Effort mobile application.

Osteoarthritis (OA) is the most common cause of disability in older adults worldwide affecting 7% of the global population, or more than 500 million people globally. Total joint replacements (TJR) can help bring relief to those with osteoarthritis when other treatment options are no longer helpful. Infection is the main reason hip and knee replacements "fail". Failure leads to repeat surgeries that are often more complicated and less likely to be successful than the first surgery. Reducing the risk of infection is extremely important, antiseptic washes and antibiotics may help us do that. After joint replacement surgery, orthopaedic surgeons wash and clean the surgical wound to lower the risk of infection. The goal of this clinical trial is to determine if the use of antiseptic solutions to wash the surgical site and placing an antibiotic directly into the wound will reduce the number of infections requiring reoperation. Patients having total joint replacements will be randomized (like flipping a coin) to receive 6 possible combinations of washes and / or antibiotics. Participants will be followed for one year after TJR to compare the rate of infection in each group.

In outpatient hand surgery, 40% of patients report moderate to severe pain within 24 hours of the operation. Effective pain management is therefore essential to ensure a comfortable and safe return home for the patient. Loco-regional anesthesia is the optimal method of analgesia for complex hand surgery. It involves the injection of a local anesthetic (LA) near the nerves responsible for the sensitivity of the arm. Following a single injection of long-acting local anesthetic, the maximum duration of analgesia is limited to approximately 13 hours, with great variability between individuals. In order to provide pain relief over a longer period of time, placing catheters near nerves has become a routine practice at the CHUM. Infraclavicular nerve block is one of the most widely used loco-regional anesthesia techniques for hand surgery. This block can be achieved either by paracoracoid (PC) or costoclavicular (CC) approach. Both approaches are currently used at the CHUM. The PC approach involves inserting a needle under the lower rim of the clavicle below the coracoid process. This approach makes it possible to reach the 3 different nerve bundles, located around the axillary artery, which are involved in the sensitivity of the hand. The CC approach, more recently described, proposes an insertion of the needle under the lower edge of the clavicle but in a lateral way to the axillary artery which makes it possible to reach the nerves at a place where the 3 main nerve bundles are still joined together. The clustering of nerve structures at the injection site may facilitate the spread of local anesthetics. Recent studies have demonstrated that the CC approach requires a smaller volume compared to the PC approach to achieve perineural blockade. The effective dose 90 (ED90) for the CC approach was 19 mL while it is 31 mL for the PC approach. This is explained by the greater proximity between the three nerve bundles targeted in the CC approach and a lower prevalence of anatomical variations at this level. However, studies on the subject are rare and do not allow conclusions to be drawn on the superiority of either approach.

The NEPTUNE triple-blind, active-placebo, adaptive, pragmatic, randomized trial aims to evaluate the effectiveness of a new intra-venous hydration strategy guided by left ventricular end-diastolic pressure (LVEDP), amount of contrast used, and baseline renal function, to prevent contrast-induced acute kidney injury (CI-AKI) and patient-oriented clinical endpoints in all-comer patients undergoing coronary angiogram and/or percutaneous coronary intervention (PCI).
