Femoro-acetabular impingement is a well known cause of damage to the acetabular labrum and chondrolabral junction. Additionally, it has been proposed that disruption of hip biomechanics resulting from a labral tear causes a faster progression towards osteoarthritis (OA). This progression has been observed to begin with breakdown of the chondrolabral junction with later development of diffuse osteoarthritis. Use of hip arthroscopy has increased dramatically in recent years to treat symptomatic labral tears and potentially avoid the morbidity and cost associated with hip osteoarthritis. Correction of labral pathology presents a technical challenge and many techniques currently exist. Increased understanding of the structure-functional relationship dictated by labral anatomy has led to the development of methods aimed at restoring functional anatomy by re-establishing the labrum's native position and contour on the rim of the acetabulum. Therefore, akin to repairing a torn meniscus in the knee, restoring the anatomic footprint of a torn labrum will reconstitute normal joint biomechanics. Despite the advances in techniques for labral repair, strategies for mitigating or repairing damage to the chondrolabral junction do not yet exist. This area has been shown to consist of hyaline and fibro cartilage. Many techniques for cartilage repair exist, although most are not feasible due to technical challenges specific to the hip joint. The management of articular cartilage defects is one of the most challenging clinical problems for orthopaedic surgeons. Articular cartilage has a limited intrinsic healing capacity, and pathology frequently results in gradual tissue deterioration. Currently, the standard surgical intervention for end-stage degenerative joint pathology is total joint replacement. Early surgical interventions for symptomatic cartilage lesions including cell based therapies such as autologous chondrocyte implantation (ACI), bone marrow aspirate concentrate (BMAC) implantation, or microfracture have been suggested to restore normal joint congruity and minimize further joint deterioration. Techniques such as ACI, which have been successfully used in the knee joint, have limited application in the hip due to the technical difficulties of open procedures.

This is a research study in minorities to compare the outcomes of two procedures that restore blood flow to the arteries of the heart. In one procedure the blockages are ballooned and then stented with a small wire mesh tube through a small incision in the wrist or the groin. The other procedure is an open-heart operation in which healthy blood vessels from inside the chest, leg, and/or forearm are used to "bypass" the blockages (like a detour). Outcomes will be measured by comparing survival and improvement in quality-of-life.

Older people with HIV (OPWH) are disproportionately impacted by cardiovascular disease (CVD) attributable to behavioral risk factors, and chronic HIV immune dysregulation resulting inflammation. Systemic inflammation is exacerbated by psychological distress via activating the immune response and driving pro-inflammatory CVD risk behaviors. There is promising evidence to suggest that mindfulness could be an effective intervention to reduce psychological distress and support behaviorally- and inflammatory-mediated CVD risk reduction. This project aims to refine and synthesize mindfulness and behavior change content from evidence-based protocols (mindfulness-based stress reduction and diabetes prevention program) to develop and pilot test a new text message-enhanced intervention called "One Mind One Heart" (OM-OH) using feedback from semi-structured interviews with OPWH in psychological distress (N=20), and my multidisciplinary mentorship team (Aim 1). An open pilot (N=5) with exit interviews and pre-post self-report assessments, will inform the initial acceptability of OM-OH and further refine OM-OH as needed (Aim 2). Finally, a pilot randomized controlled trial (RCT; N=50) will be conducted to a.) evaluate benchmarks of feasibility and acceptability of study methods and refined OM-OH compared to enhanced usual care, and b.) investigate potential for effects on psychological distress, inflammation, and behavioral CVD risk (Aim 3). Findings will provide the foundation for an R01 application to conduct an efficacy trial of OM-OH to reduce inflammatory-mediated CVD risk among OPWH.

The ascending aorta conducts blood from the heart to the rest of the body. The ascending aorta can become enlarged, and the risk of tearing and rupturing becomes higher with larger aorta. When the ascending aorta tears or ruptures, the risk dying is high even if surgery is done as soon as possible. Traditionally, when the ascending aorta gets above 5.5 cm, surgery is recommended to replace the aorta. However, this threshold is based relatively weak evidence, and sometimes patients with smaller aorta can tear or rupture. On the other hand, surgery carries its own risk as well. Since there are risk of waiting or doing surgery, there is currently no great support for either approach for patients with a smaller aorta. In the TITAN SvS trial, patients with an ascending aorta between 5.0 to 5.5 cm is assigned by chance to the early surgery group, in which they will undergo replacement of aorta, or the surveillance group, in which they will be closely monitored. The chance of dying or suffer tearing or rupture of aorta between the two groups will be compared. The result of the trial will guide future practice for patients with enlarged ascending aorta. This is a prospective, multi-centre randomized control trial that compares the all-cause mortality, aneurysm-related aortic events, rate of stroke, and quality of life for those patients undergoing early elective ascending aortic surgery to those patients undergoing surveillance. Patients referred for an ascending aortic aneurysm that meets the inclusion criteria will be randomized to the early elective surgery group or the surveillance group. Recruitment will end when the desired sample size is reached, and the patients will be followed for a minimum 2-year period. The primary objective of the trial is to compare the composite outcome of the all-cause mortality and incidence of acute aortic events between surveillance and elective ascending aortic surgery for patients with degenerative or bicuspid valve-related ascending aortic aneurysm after 2 years of follow up. The hypothesis is that the early surgery group will have a significantly lower all-cause mortality and incidence of acute aortic events at 2 years of follow up compare to the surveillance group. The result of this trial will provide evidence based guidance in the appropriate management of ascending aortic aneurysm based on the size criteria, and establish a large database for future investigations.

The investigators are doing this research to test whether parents of children ages 2-7 can better manage their child's anxiety by completing a brief, online, self-guided parent education program. One way to provide anxiety management skills to more children, and to potentially prevent worsening outcomes, is to offer online and self-guided educational programs that parents can complete without a clinician. This randomized trial will evaluate the effects of two brief, online, self-guided parent education programs designed to improve parents' understanding of anxiety and teach parents way to help their children cope with anxiety. Parents will be randomly assigned to one of the three programs. The main aim of the study is to examine whether the parent programs, compared to an educational control reduce parental accommodation of anxiety across a 1-, 4-, and 8-month follow-up period. As a secondary aim, the investigators will explore whether the parent programs reduce children's anxiety symptoms over the 8-month follow-up period. Results will inform the development of a scalable, low-cost model for promoting access to evidence-based treatment to young children.

The Comprehensive HHT Outcomes Registry of the United States (CHORUS) is an observational registry of patients diagnosed with Hereditary Hemorrhagic Telangiectasia (HHT). The purpose of this study is to better understand HHT, the symptoms and complications it causes, and the impact the disease has on people's lives. The investigators will collect long-term information about the participant, allowing us to understand how the disease changes over time, and what factors can influence those changes. Ultimately, this should help improve treatments for the disease. Another important goal of the study is to provide a way to contact people to participate in future clinical trials and other research. The registry will be a centralized resource for recruitment for clinical trials. People in the registry will not be obligated to join any of these additional studies, but if interested, can agree to be contacted if they may be eligible for a study. Participants will: - Be asked to provide permission to collect information from their medical records, including things like demographic information, diagnosis information, family history, test results, treatment information, symptoms, complications, lifestyle and other relevant medical information. - Be asked study-related questions by phone or at a clinic visit. - Be asked study-related questions every year after enrollment for up to 10 years or until the study ends. A member of the study team will communicate with participants by phone or at clinic visits to collect information regarding any changes to their health over the previous year/s including new test results, treatment information, symptoms, and complications from HHT.
