The study will compare the effectiveness of endoscopic surveillance and endoscopic eradication therapy (EET) for the management of Barrett's esophagus (BE) and low-grade dysplasia (LGD).

This study is for participants who have tricuspid regurgitation, a condition in which your heart's tricuspid valve does not close tightly which causes blood to flow backwards in the incorrect direction. This condition increases the workload on the heart and if left untreated, it can increase the risk of worsening heart failure. In this study, a device called the PASCAL Transcatheter Valve Repair System will be used to treat the tricuspid regurgitation. The PASCAL Transcatheter Valve Repair System is an investigational device meaning it has not been approved for commercial use by the US Food and Drug Administration (FDA). In this study participants will be randomized, meaning randomly assigned like drawing straws, in a 2:1 fashion to either receive the PASCAL Transcatheter Valve Repair System (treatment group) or optimal medical therapy (OMT) (control group). OMT means your medications will be adjusted as needed to provide the most benefit possible. Participants randomized to the OMT group may be eligible to receive the device after completing 2 years of follow up. Participants not eligible for randomization may be eligible for the registry portion of the study if approved by the sponsor. The registry arm participants will not be randomized but will undergo the procedure to place the device.

Participation in this study will last about 5 years and involve up to 15 visits for those in the treatment or registry group and 11 visit for those in the control group. Study related procedures include a right heart catheterization (test to measure the pressures in the heart), echocardiograms (ultrasound test of heart), electrocardiogram or ECG (test of the heart's electrical system) blood work, questionnaires, hall walk test, and physical exam.

The purpose of this research is to compare the risks and benefits of two different procedures used to help patients with mitral valve regurgitation (also known as MR). MR is a condition where the valve does not close fully when it is supposed to, and some blood can then leak back into the left atrium instead of circulating to the rest of the body. The treatment options this study will compare are: (1) transcatheter edge-to-edge repair (abbreviated as TEER; which is a catheter procedure for repairing the mitral valve that doesn't require surgery to open up the heart) and (2) mitral valve repair surgery, which is an open-heart surgical procedure. There are no new or "experimental" procedures being tested in this study: both treatment options are well-established treatments and are regularly performed in patients who have MR.

The purpose of this study is to observe the safety and effectiveness of the Indigo Aspiration System. This study will help determine how study participants recover when the study device is used to remove the clot from the deep veins.

This study is enrolling participants with severe aortic stenosis, which is narrowing of one of the heart valves. This condition reduces the amount of blood that can get to the body. This study is collecting data on the safety and effectiveness of an investigational (not yet approved for commercial use by the US FDA (Food and Drug Administration)) device called the ACURATE Aortic Valve System. The procedure to place the device, referred to as TAVR - transcatheter replacement of aortic valve is done in place of open heart surgery. In this study the ACURATE Aortic Valve System will be compared to two commercially available Aortic Valve Systems (valve replacement systems). Participants will be randomized (assigned by choice, like a flip of a coin, in a 1:1 fashion so 50% chance of being assigned to either group like the flip of a coin) to one of two groups. One group will receive the ACURATE Aortic Valve System while the other group will receive one of the commercially available systems. This study will last up to 10 years. Pre-procedure testing is done and reviewed by an eligibility committee to confirm you qualify. Study visits will occur prior to your procedure, during the procedure and throughout your hospital stay, and prior to discharge. Additional visits will occur 1 month and 6 months after your discharge, and then you will either seen or telephoned once per year for the next ten years. Study related testing includes CT scans, physical exams, echocardiograms (ultrasound test of the heart), blood work, and questionnaires.

This study is examining the use, safety and performance of an investigational, meaning not approved for commercial use or sale by the US Food and Drug Administration (FDA) device called Transcatheter Mitral Valve Replacement (TMVR). The TMVR is a device used to treat mitral valve disease in patients with heart failure (weakened heart muscle). The device is placed by a non surgical approach using a delivery catheter (hollow tube) placed in your blood vessel at the top of your leg and directed up to your heart. This five year study will include a screening process to determine you meet eligibility criteria. If you qualify you will then be seen for a baseline visit, undergo the procedure to place the device, day after procedure, at hospital discharge, 1,3,6, 12 months, then yearly for up to 5 years. Study related testing includes physical exams, medication review, 6 minute hall walk test, questionnaires, blood work, CT scans, electrocardiogram or ECG (recording of your heart's electrical activity) and echocardiogram (ultrasound test of your heart).

The study will include 9 key informant interviews discussing how patients developed their impression of the benefit of an implant and how patients prefer expectation data be relayed. No video recordings will be performed during interviews. Interview notes or audio recordings will be taken and uploaded into a password protected network server. The results of interviews will mainly be descriptive. To test the plasticity of preoperative patient expectations and the impact of the CI evaluation the CIQOL expectations form will be administered prior to CI evaluation, directly after the CI evaluation, and prior to surgery for all patients who are undergoing cochlear implantation and meet inclusion/exclusion criteria and agree to participate. The decisional conflict scale will also be administered directly after the CI evaluation and prior to surgery for the above patient group. The 9 patients who undergo key informant interviews will also be part of the larger study group of 200 patients and have the same surveys administered and be subject to the same inclusion/exclusion criteria. The group of patients will also be asked about how they prefer expectation and QOL data to be relayed. All survey data will be collected in a secure RedCap database. Patients expectations at the three preoperative timepoints will be compared using paired T-tests. Data regarding how patients develop expectations and how they prefer expectation data to be presented to them will be mainly qualitative and discussed in terms of the most common themes from patient surveys and interviews. When exploring how patients prefer expectations and QOL data to be relayed we intend to include numbered clinical vignettes relaying differing levels of hearing capability. We will compare relaying information through vignettes to more conventional outcome measures such as speech recognition and QOL scores to determine which is the more effective means of communication.

This study is being done on patients who have heart failure, a condition where the heart muscle weakens and enlarges and cannot pump blood effectively. The purpose of this study is to assess the safety and effectiveness of a new device called the AccuCinch Ventricular Restoration System and compare it to treatment with standard heart failure medications alone. The AccuCinch Ventricular Restoration System consists of anchors, which attach to your heart muscle, sliders to connect the anchors and a thread like cord that goes through the anchors and is cinched to make your enlarged heart smaller so it can pump more efficiently. The device is implanted in one of the lower pumping chambers of the heart (called left ventricle). The study will have two groups, the treatment group in which participants undergo the device implant in addition to taking heart failure medications and the control group in which participants are treated with heart failure medications alone. Participation will last up to 5 years.

The goal of the COSMID (Comparison of Surgery and Medicine on the Impact of Diverticulitis) trial is to determine if elective colectomy is more effective than best medical management for patients with quality of life-limiting diverticular disease. The COSMID trial focuses on both patient-reported outcomes and clinical outcomes that matter to patients. The results are expected to establish an evidence-based approach to the care of millions of patients per year in the United States and help people impacted by this common condition make more informed treatment decisions.

The purpose of this study is to determine whether a new medical technology can help reduce post-operative total knee or hip pain when combined with a Cognitive-Behavioral intervention (CBI).

This new medical technology, is called transcranial direct current stimulation (tDCS), it uses a very small amount of electricity to temporarily stimulate specific areas of the brain thought to be involved in pain reduction. The electrical current passes through the skin, scalp, hair, and skull and requires no additional medication, sedation, or needles.

This study will investigate the effects of tDCS, the Cognitive-Behavioral (CB) intervention and their combination on pain among veterans following total knee arthroplasty (TKA) or total hip arthroplasty (THA). You may benefit in the form of decreased pain and opioid requirements following your knee or hip replacement surgery. However, benefit is only likely if you are randomized to one of the 3 (out of 4) groups.

This study hopes to determine the effects of these interventions and their combined effect on post-operative pain, opioid use and functioning during the 48-hour post-operative period following a total knee or hip replacement.
