The goal of this exploratory, mixed-method design study is to gather qualitative and quantitative data obtained through interviews and questionnaires with veterans who are currently enrolled at the VA for healthcare. The main question this study aims to answer is: How do veterans aged 65+ who are enrolled for care at the VA understand ketamine assisted psychotherapy for depression and for end-of-life distress? Using a story-completion approach, participants will be provided with a brief story starter involving a fictitious character and scenario and asking them to complete the story. Few contextual details will be offered about the character. In responding to ambiguous cues, participants are thought to project their conscious and subconscious perceptions about the phenomenon in question onto the story, a useful method for exploring stigmatized topics. The purpose of this exercise is to ascertain the participants attitudes and perceptions regarding ketamine assisted psychotherapy. Read Less

The SARS-CoV-2 virus causes COVID-19, which ranges from mild initial symptoms to severe multi-organ dysfunction. While some patients recover to their baseline states, others develop a long COVID, or post-acute sequelae of SARS-CoV-2 (PASC) consisting of symptoms persisting \>2-6 months post-infection. PASC symptoms include post-exertional malaise, fatigue, and heart palpitations as well as incident GI disorders, cognitive dysfunction, and arthritis. Based on prevalence/incidence studies, it is estimated that more than 30 million people in the US have ever developed PASC with 10-11% of patients or 11 million people continuing to feel symptoms to the present day10. SARS-CoV-2 vaccines are only \~32% effective against infection at 4 months post-vaccination11, only 15% effective against the development of PASC12, and only 20% of American adults have received an updated booster as of December 202313. It is therefore imperative that the scientific community make progress in identifying underlying causes of PASC to develop effective treatments. This study will identify microbial metabolites associated with PASC-mediated gut dysbiosis and establish a tractable in vitro model to test T cell-gut epithelium dynamics to develop novel bio-therapeutics for multiple post-viral conditions. This case-control study will collect biospecimens (matched stool \& blood) samples from 400 people with and without long COVID (200 participants/group) to understand how COVID-induced dysbiosis impacts symptom severity, immune suppression, and gut barrier dysfunction both ex vivo and in vitro.

Prediabetes effects 96 million people 18 years of age or older. It is important to identify treatment options to slow or prevent progression to diabetes. It is also critical to assess the potential of medications like sodium glucose transporter 2 inhibitors to reduce the risk of cardiovascular events and kidney complications, both common and costly complications of diabetes. This is a 12-week, open-label pilot feasibility study assessing the use of empagliflozin in prediabetes. Read Less

The investigators hypothesize that Shockwave with DCB is non-inferior to surgical endarterectomy for common femoral artery (CFA) stenosis with regard to primary efficacy and safety endpoints. The study will challenge the current guideline that recommends common femoral endarterectomy (CFE) as the primary treatment for symptomatic CFA stenosis. Read Less

The goal of this randomized control trial is to determine the impact of post-frenotomy manual manipulation on revision rates and breastfeeding outcomes. We hypothesize that post-frenotomy manipulation will reduce the rate of sublingual frenulum regrowth, and subsequently frenotomy revision rates, thereby improving breastfeeding performance. Infants with ankyloglossia undergoing frenotomy will be randomized into two groups: the intervention group (post-frenotomy manipulation) and the control group (no intervention). Parents in the intervention group will be instructed to perform tongue stretching and suck "re-training" exercises four times daily for 2-3 weeks, beginning 24 hours post-procedure. To monitor adherence and assess any complications, investigators will conduct a follow-up phone call one week after the procedure. Parents in the control group will not be instructed to perform any post-procedural manipulation. All participants will have a mandatory in-person follow-up 2-3 weeks postoperatively, during which breastfeeding outcomes and the need for frenotomy revision will be evaluated. Read Less

Femoroacetabular impingement (FAI) is one of the most common mechanisms leading to the development of early cartilage and labral damage in the non-dysplastic hip. Anatomic abnormalities of the proximal femur and/or acetabulum result in repetitive injury during dynamic hip motion, leading to abnormal regional loading of the femoral head-neck junction against the acetabular rim. The resulting damage to the cartilage, labrum, and surrounding capsular structures predispose the patient to developing hip pain and early osteoarthritic changes. Clinically, patients with FAI are a heterogeneous group, with a wide array of presentation from pain to instability that may or may not be related to activity. To date no studies have identified specific prognostic indicators associated with successful surgical treatment of FAI, leaving surgeons without adequate criteria to determine which patients are best suited for arthroscopy. The investigators propose to address this critical knowledge gap by identifying the patient characteristics and morphological features of the hip that are associated with the optimal clinical outcomes in patients undergoing hip arthroscopy or non-operative management for treatment of suspected FAI in order to establish a treatment algorithm for FAI patients.

This study is a biobank of specimens and clinical data for use in current and future research to better understand the cholestatic liver diseases primary biliary cirrhosis/cholangitis (PBC) and primary sclerosing cholangitis (PSC). Read Less

The purpose of this project is to compare a novel sensorimotor ankle rehabilitation training (SMART) protocol for Lateral ankle sprains (LASs) against a standard of care (SOC) protocol to determine if it is more successful at producing successful one-year outcomes and lower rates of re-injury and improved health. This will address the identified needs for evidence-support and reintegration strategies to improve understanding of the management of patient rehabilitation strategies throughout the rehabilitation process following neuromusculoskeletal injury. The project will validate an innovative rehabilitation approach while providing metrics of success using a variety of clinical and innovative markers. Read Less

The research objective is to characterize the risk of a major adverse cardiovascular event (MACE) among new users of naldemedine versus new users of lubiprostone and new users of naloxegol as comparator opioid induced constipation (OIC) medications. Read Less

The investigators are conducting this study with men that have prostate cancer and are getting standard of care treatment with the drugs abiraterone acetate and prednisone. The study will follow men with prostate cancer from initiation of participation in the study and for up to 10 years. The reason for the study is that researchers think that there may be a connection between the race and ethnicity of men with prostate cancer and how well the standard treatments work for the participants.
