This proposed collection of primary tumor cells lines will benefit esophageal cancer research within the University Health Network. This collection of gastro-esophageal tumor samples will be used to grow primary tumor cell lines, which will provide researchers with ready samples of various gastro-esophageal cancers. This will help to address the issue of access to these cell lines due to the limited number of patients with gastro-esophageal tumors, and high rates of contamination.

Patients with cancer are prone to have blood clots, which are usually treated with blood thinners. The main complication of blood thinners is bleeding. This is especially a concern when the number of platelets in the blood is lower than 50,000 per microliter. The role of platelets is to stop bleeding, so when the number of platelets is low, patients are at a higher risk of bleeding. Cancer patients are prone to have lower platelet numbers due to cancer therapies and/or cancer itself. It is not clear what the best treatment is for cancer patients who need blood thinners for a blood clot but have low platelet counts. The investigators plan to do a small study called a pilot study to help plan for a larger study in such patients. In the pilot study, investigators will include 50 patients with cancer, low platelet counts, and a blood clot diagnosed within 4 weeks. Patients will be randomly assigned to one of the two treatment strategies: the full dose of blood thinners along with platelet transfusion or a reduced dose of blood thinners without platelet transfusion. The investigators will follow all patients for 90 days. If this pilot study is successful, it will help lead to a much larger trial, which will provide important information on the best treatment strategy in these patients.

We propose a randomized, double-blind controlled trial comparing arthroscopic release with arthroscopic debridement for the management of chronic tennis elbow in an effort to definitively determine whether arthroscopic tennis elbow release is an effective treatment of tennis elbow, and to further provide better recommendations for the use of this procedure, in an effort to improve patient care.

Holmium laser enucleation of the prostate (HoLEP) is routinely performed with 24F, 26F, and 28F laser scopes. Proponents of larger caliber scopes suggest that the larger scope size allows for improved visualization, hemostasis, and operative efficiencies. Proponents of a smaller scope diameter suggest that by eliminating the need for pre-HoLEP urethral dilation to accommodate a larger scope. It has also been proposed that a smaller caliber scope is less traumatic to the urethra resulting in lower rates of bladder neck contracture and urethral stricture disease. Currently, to our knowledge, there are no level one evaluation examining scope size 22F versus 26F sheath in laser enucleation outcomes. The aim of our study is to determine if a smaller diameter scope is associated with improved laser enucleation time, post-operative recovery, rates of same-day discharge, or increasing intra-operative or postoperative complication rates

This is a multi-center, Phase 1a study to assess the safety, tolerability, PK, and PD of VGA039 following single IV or SC dose administration in healthy subjects and Von Willebrand disease patients.

Coronary angiography is performed to evaluate for obstructive coronary artery disease. This is commonly performed via the transfemoral or transradial approach with the latter increasing in frequency. One of the most common complications of transradial access is radial artery occlusion occurring in \~5% of patients which prohibits the use of the radial artery in the future. There is evidence to support the use of intraprocedural anticoagulation to mitigate the risk of radial artery occlusion however the role of post-procedural anticoagulation has not been previously evaluated. Rivaroxaban is a direct oral anticoagulant (DOAC) with a safety profile superior to that of vitamin K antagonists. Given the safety profile, ease of use, and feasibility of DOAC therapy, our study will endeavor to evaluate the use of rivaroxaban 15mg orally once daily for 7 days after transradial access and the impact this has on the rate of radial artery occlusion.

Treatment resistant depression (TRD) is a major global health concern, and there is a crucial need to develop novel effective treatments. The medial forebrain bundle (MFB) is a recently described DBS target, with reported rapid onset of antidepressant effects. A recent small randomized trial reported a 100% response rate. The subcallosal cingulate cortex (SCC) is the most commonly used target in DBS for depression. Herein, the investigators will conduct a sham-controlled randomized trial of DBS to the MFB or SCC for TRD.

Lung cancer is the leading cause of death in the world. Overall 5-year survival rate is fewer than 10% and the effectiveness of conventional chemotherapy is limited. The new knowledge shows the correlation between genetic alteration and effective of chemotherapy. Therefore non-surgical modalities to obtain tumor specimens for genetic alteration analysis are particularly critical in lung cancer, since many patients have advanced disease at the time of first presentation, and are therefore not eligible for radical surgery. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) samples obtained during diagnosis of lung cancer can be used for molecular analysis that will predict response to treatment and prognosis. In this study, we will detect specific target molecules related to the effectiveness of treatment (surgery, chemotherapy, radiotherapy) and prognosis in patients with lung cancer using EBUS-TBNA samples and its combined with xenograft technology.

This is a prospective, multi-center, open-label clinical trial intended to evaluate the safety and effectiveness of the MobiusHD® in patients with heart failure and reduced ejection fraction.

The goal of this a single arm prospective study is to evaluating the 3-month return of urinary continence outcomes of patients undergoing the transvesical retzius sparing robotic radical prostatectomy (TRS-RALP) for standard of care surgical prostate removal for treatment of prostate cancer. The main question it aims: To have patients respond to questionnaires to collect exploratory data on patient's quality of life (QoL; EuroQol-5 Dimension 5-Level \[EQ-5D-5L\] and prostate cancer related urinary, bowel, and sexual function questionnaires (Expanded Prostate cancer Index Composite for Clinical Practice (EPIC-CP), at their standard of care perioperative visits at baseline and at 4 weeks, 3- and 6-months post operatively.
