Falls are by far the leading cause of accidental injury and death in older adults. The Veteran population is more severely affected by falls since it is significantly older than the overall population (45% over 65 years of age vs. 13%); and Veterans would benefit substantially more from an accurate diagnosis and treatment of fall propensity. Despite its importance, much is still unknown about the manner in which balance control is compromised by age and disease. Therapeutic interventions for people who are at risk of falling have proven to be of limited utility. Engineering methods are well suited to study and evaluate balance; but have to date been applied to overly simplified scenarios that lack the complexity to probe the musculoskeletal and neurophysiological bases for balance and falls. The long term objective of this research, which began with a VA Rehabilitation Research & Development (RR&D) Career Development Award (CDA-2), is to develop improved directives and protocols for the diagnosis and treatment of balance-related posture and movement coordination problems. This proposal significantly advances engineering methods to address existing gaps in the diagnosis and treatment of balance impairments through the development of a Balanced Assessment and Training Protocol (BATP). The BATP continuously challenges subjects to perform reaching tasks at the limits of their balance for an extended period of time, and increases these limits as subjects demonstrate improved performance. The goal of this tool is to quantitatively assess and improve at-risk individuals' ability to maintain balance when disturbed by volitional movements of the body and its parts-an important class of balance disturbances integral to many activities of daily living that can precipitate falls. The BATP focuses on performance at and just beyond the limits of balance, unlike most such tests and training protocols that do not challenge subjects in this way. The BATP's most immediate and salient metric is the limiting boundary of standing reach; and we hypothesize that expanding this boundary, as the BATP is designed to do, will improve balance and make individuals more resistant to falls (in the context of expected balance disturbances). Confirmation of this hypothesis could provide a new perspective on existing training protocols' modest success rates, and direction for the design of new protocols with the potential to significantly improve these rates. [Though the BATP is a training platform, we also believe that the performance metrics and analytical results produced by it can form the basis for new diagnostic measures that more reliably and precisely quantify and explain balance performance problems; and track changes in them over time.] Such diagnostic and treatment protocols would be particularly beneficial to the VA Health Care System, as it would lead to improvements in: patient throughput, quality of care, and treatment costs. Though this proposal targets the aging Veteran population, the BATP is a general tool that can aid in the diagnosis and treatment of balance disorders arising from conditions other than aging. These include obesity, diabetes (which often leads to lower extremity muscle degeneration and peripheral neuropathy), sarcopenia, vestibular disorders, and neurological disorders such as stroke. Veterans whose balance has been compromised by Traumatic Brain Injury (TBI) (whether combat-related or not) may also benefit from the BATP.

This study is focused on males who have Hemophilia B and who need regular preventive treatment with factor IX protein (FIX) replacement therapy to prevent and also to control their bleeding events. The aim of the study is to gather at least 6 months of information on bleeding events for each individual participant while they continue to use their usual FIX replacement therapy. There is no experimental treatment being tested in this study. The study is informational, and part of a larger program to understand and treat Hemophilia B with a potential experimental new therapy in the future. There is no obligation to agree to taking part in this future study. The study is looking to answer several other research questions to help understand each participant's individual disease characteristics, including: - How often to use FIX replacement therapy, both on a regular basis (prophylaxis) and as needed to treat bleeding events - Measurement of FIX activity (factor IX is a clotting factor) by different laboratories using different types of tests in Hemophilia B participants - Possible complications from the FIX replacement therapy the patient receives (usual standard of care will continue to be used) - How quality of life is affected by Hemophilia B - How joint health is affected by Hemophilia B - How often the participant visits the emergency room, urgent care center, physician's office, hospital, or has a telemedicine visit as a result of bleeding events - Whether the body makes antibodies (a protein produced by the body's immune system) against the FIX replacement therapy you receive, which could make the drug less effective or could lead to side effects

This is an unblinded, randomized clinical study comparing the efficacy of DNA damaging chemotherapy using carboplatin, to standard of care therapy for patients who have metastatic castrate resistant prostate cancer. This trial will use olaparib or carboplatin as initial therapy with crossover to the alternate or second-line drug after first progression for patients with tumors containing BARD1, BRCA1, BRCA2, BRIP1, CHEK1, FANCL, PALB2, RAD51B, RAD51C, RAD51D, or RAD54L inactivating mutations. Participants are randomized (1:1) and receive either carboplatin (AUC 5, IV) every 21 days, first or olaparib taken orally (300 mg), twice daily in 28 day cycles, until intolerance, complete response, or progression by Prostate Cancer Working Group 3 (PCWG3) criteria. Participants then crossover from the first-line therapy to the second-line therapy with the opposite study medication and receive treatment to intolerance or progression (whichever is first). Enrolled participants will be allowed to crossover to second line therapy if they continue to meet initial eligibility criteria, and at least three weeks have elapsed since last administration of either carboplatin or olaparib. Throughout the study, safety and tolerability will be assessed. Progression will be evaluated with bone scan, CT of the abdomen/pelvis, or MRI and PSA as per PCWG3 criteria.

Prospective, controlled, multicenter clinical investigation with four trial cohorts: Randomized, Non-repairable, Severe Mitral Annular Calcification (MAC) and Severe Mitral Annular Calcification Continued Access Protocol (MAC CAP). Subjects in the Randomized cohort will be randomized in a 1:1 ratio to the trial device or to the MitraClip system. Subjects in the Non-repairable, Severe MAC, and Severe MAC CAP cohorts will receive the trial device. The objective of the Clinical Trial to Evaluate the Safety and Effectiveness of Using the Tendyne Transcatheter Mitral Valve System for the Treatment of Symptomatic Mitral Regurgitation (SUMMIT) is to evaluate the safety and effectiveness of the Tendyne Transcatheter Mitral Valve System for the treatment of patients with symptomatic, moderate-to-severe or severe mitral regurgitation or for patients with symptomatic mitral valve disease due to severe mitral annular calcification. This randomized controlled trial will provide the opportunity to evaluate the safety and clinical benefits of the Tendyne Transcatheter Mitral Valve System compared to the MitraClip System in patients with symptomatic, moderate-to-severe or severe mitral regurgitation, within approved MitraClip indications. In addition, the safety and effectiveness of the Tendyne Transcatheter Mitral Valve System will be evaluated in patients with severe mitral annular calcification who are at prohibitive risk for mitral valve surgery. Patients who are not suitable for mitral valve surgery for reasons other than severe mitral annular calcification and are also not suitable for transcatheter repair with MitraClip, will be enrolled in the Non-repairable cohort. Subjects will be seen at screening, pre- and post-procedure, discharge, 30 days, 3 months, 6 months, and annually through 5 years.

This is a proposal to develop a Balanced Reach Training Protocol (BRTP) to evaluate and train dynamic standing balance. The BRTP is based upon the Balanced Reach Test (BRT) that the investigators previously developed and validated. In the BRT subjects stand and point to a target disk moving unpredictably across a large projection screen in front of them without stepping. Body movements undertaken to track the disk are integral to many daily activities and represent an important class of "expected" balance disturbances that can precipitate falls. The BRTP employs engineering and psychophysical methods, and exploits advances in real time computing in a novel and innovative way to more effectively evaluate and train balance function. The BRTP presents a challenging reaching/tracking task that subjects perform at their limit of balance. The BRTP is an objective, quantitative test that can evaluate balance function without floor or ceiling effects, and train balance across the spectrum of aging, disease, and injury.

Intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) has been shown in clinical trials, registries, and meta-analyses to reduce recurrent events after PCI. This is accomplished by improving the angiographic result with lesion and vessel assessment to guide stent selection and implantation and intravascular imaging following stent implantation to ensure an adequate treatment endpoint has been achieved. Despite extensive literature supporting the use of IVUS in PCI, utilization remains low in the United States. An increasing number of high-risk or complex lesions are being treated with PCI and we hypothesize that the impact of IVUS in these complex lesions will be of increased importance in reducing clinical adverse events while remaining cost effective.
