Data on valve performance following ViV-TAVR has usually been obtained with the use of Doppler-echocardiography. However, some reports have shown significant discordances in the evaluation of mean transvalvular gradient between echocardiography and catheterization, with an overestimation of the real gradient with echo (vs. cath) in most cases. Thus, the incidence of procedural-device failure may be lower than that reported in the ViV-TAVR literature,

20 - 99This 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.

18 - 99This project aims to study an innovative intervention, the eG2 Intervention, developed by speech-language pathologists at the Centre hospitalier de l'Université de Montréal to improve therapeutic adherence and prevent dysphagia in patients treated with chemoradiotherapy for head and neck cancer. The innovation consists in offering a speech therapy intervention that is 1) virtual, 2) group-based (whereas it is usually individual) and 3) involves a patient partner. This intervention has the potential to improve quality of care, accessibility to services and optimize health care resources.

Over 18Burn patients very commonly develop abnormal scars after injury which can be red, raised or elevated, painful and very itchy. They can prevent normal movement of hands and other joints and lead to ugly deformities which makes physical and psychological recovery very difficult. This proposal seeks to test the usefulness of a cream called Nefopam to prevent and treat these bad scars after burns and other injury to the skin. Nefopam is a drug that has been used as a pain medicine in Europe but has been found to have anti-scarring properties in rats and pigs. It has been tested in healthy people and found to be well tolerated and safe. The study purposes to make a scratch in the hip skin in 60 adult burn patients at two burn unit sites, the University of Alberta and the University of California at Davis, Sacramento CA. Burn patients in the study will have a scratch wound in the skin of the each side of the hip, part way through the thickness of the skin which is shallow at first but gets deeper. This scratch is made with a special guide which precisely controls the length and depth of the scratch so that each scratch is the same. Part of the scratch heals without scar and the deeper part heals with a red raised scar over a small region less than 2 inches long. One side will be treated with the drug and the other with a control or placebo are in a white cream that is indistinguishable, where you cannot tell which side contains the drug. Once the wound is nearly healed, usually less than 21 days, the cream will be applied twice daily for three weeks. Measurements will be done about once per month for four months where the healing scratches will be photographed, measurements of the thickness made with ultrasound and mexameter for scar color or pigment and redness. Ultrasound is a painless probe that uses sound waves to measure scar thickness and mexameter is a painless probe on the surface of the scratch to measure color and redness. Both measurements take only minutes to complete. Patients will be asked to answer a scar assessment form about on how they feel each scratch during the treatment and the research staff will also the complete scar form as well. It is the aim of the study to find a cream the works to prevent and reduce scarring after burn injury in military or civilian patients. In the future, an useful cream for scarring in burn patients may also be helpful for other skin damage which leads to scarring.

18 - 65The goal of this study is to compare 2 medications that are commonly used to prevent excess uterine bleeding (postpartum hemorrhage, or PPH) following cesarean delivery (CD), oxytocin and carbetocin. Most of the trials evaluating the preventative role of oxytocin and carbetocin after CD have focused on patient with low-risk of PPH. This trial will focus on patients that are at increased risk of PPH, with risk factors such as: multiple gestation (twins, or more multiples), large baby, polyhydramnios (excess amniotic fluid), history of PPH, body mass index greater than 40, diabetes mellitus, hypertension, and placenta previa. The investigators hypothesize that carbetocin would be more effective than an oxytocin regimen in reducing the risk of PPH in patients undergoing CD with any of the biological high-risk factors.

The primary objective of the study is to evaluate the objective response rate (ORR) of belzutifan per response evaluation criteria in solid tumors version 1.1 (RECIST 1.1) by blinded independent central review (BICR).

Over 12When people break their fingers, sometimes surgery is needed to align the bones to heal them properly. There are different ways to fix broken bones in hands, such as plates, pins, or screws. Each method has pros and cons; fixing a broken bone with plates is usually a larger surgery with more cutting but holds the bones very securely. Pins require little to no cutting but the patient needs to immobilize their hand for a few weeks afterwards. Screws are a newer method of fixing broken fingers that requires little cutting and also holds the bones securely. The goal of this study is to compare the effectiveness of using pins versus screws in surgery for broken fingers. The investigators are studying whether using screws leads to better hand function, patient satisfaction, and quicker return to work.

Over 18Our intent is to establish the International Registry to Improve Outcomes in Men with Advanced Prostate Cancer (IRONMAN) as a prospective, international cohort of minimum 5,000 men with advanced cancer, including men with mHSPC and M0/M1 CRPC. The goal is to establish a population-based registry and recruit patients across academic and community practices from Australia, Barbados, Brazil, Canada, Ireland, Jamaica, Kenya, Nigeria, Norway, Spain, South Africa, Sweden, Switzerland, the United Kingdom (UK), and the United States (US). Target accrual number and number of participating sites are subject to change based on accrual, funding, and interest in participation by other international sites. This cohort study will facilitate a better understanding of the variation in care and treatment of advanced prostate cancer across countries and across academia and community based practices. Detailed data will be collected from patients at study enrollment and then during follow-up, for a minimum of five years. Patients will be followed prospectively for overall survival, clinically significant adverse events, comorbidities, changes in cancer treatments, and PROMs. PROMs questionnaires will be collected at enrollment and every three months thereafter. Physician Questionnaires will be collected from all participating sites at patient enrollment, time of first change in treatment and/or one year follow-up, at each subsequent change of treatment, and discontinuation of treatment. As such, this registry will help identify the treatment sequences or combinations that optimize overall survival and PROMs for men with mHSPC and M0/M1 CRPC. By collecting blood at enrollment, time of first change in treatment and/or one year follow-up (plasma, cell free DNA, buffy coat / RNA), this registry will further identify and validate molecular phenotypes of disease that predict response and resistance to specific therapeutics. Additionally, every effort will be made to collect blood specimen at each subsequent change in treatment due to progression of disease. When feasible, existing tumor tissue may be collected for correlation with described blood based studies. All samples will be used for future research. This cohort study will provide the research community with a unique biorepository to identify biomarkers of treatment response and resistance.
