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.

The objective of C2R is to promote the rapid initiation and completion of enrollment in the CREST-2 randomized clinical trial (clinicaltrials.gov ID NCT02089217). Patients with severe symptomatic and asymptomatic carotid artery occlusive disease will be treated with carotid artery stenting (CAS) performed by experienced and skilled interventionists. Interventionists' eligibility will be determined by a multi-specialty Interventional Management Committee (IMC). Patient eligibility will include patients with standard or high-risk, symptomatic or asymptomatic carotid artery disease. Patients will be followed for the occurrence of post-procedural complications. The primary safety and quality endpoint will be the occurrence of any stroke or death within the 30-day period following the stenting procedure. The safety and quality results from C2R will guide selection of interventionists for participation in the CREST-2 randomized clinical trial. Enrollment into C2R will begin in 2015 and continue until publication of the primary results of the randomized trial.

Chronic Obstructive Pulmonary Disease (COPD) is defined as an impaired ability to move air within the lungs and is a major public health problem that is projected to rank fifth worldwide in terms of disease burden and third in terms of mortality. Chronic bronchitis (CB) is a common clinical phenotype within the umbrella of a COPD diagnosis and is classically defined as chronic cough and sputum production for 3 months a year for 2 consecutive years2, but many studies have used different definitions to define it- chronic cough and sputum production for one year or cough and sputum production on most days of the week. CB is associated with multiple clinical consequences, including; the worsening of lung function decline, increasing risk of acute exacerbations of COPD, increased risk of developing pneumonia, reduced health related quality of life, and an increase in all-cause mortality.

Prospective, controlled, multicenter clinical investigation with three trial cohorts: Randomized, Non-repairable, and Severe Mitral Annular Calcification (MAC). 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 and Severe MAC 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.

Clinical guidelines (AASLD) recommend the use of abdominal ultrasound (US) for surveillance testing for the early detection of Hepatocellular Carcinoma (HCC). The serum protein biomarker alpha-fetoprotein (AFP) is commonly used to augment US but its use alone is not recommended by clinical guidelines. Despite evidence that HCC surveillance improves early detection and reduces mortality from HCC, current HCC surveillance tests lack sensitivity, leaving a significant proportion of patients to present with late-stage disease. The Glycotest HCC Panel has shown better sensitivity than AFP, which is ineffective for the detection of early-stage HCC. This clinical study seeks to validate the Glycotest HCC Panel using a large multicenter cohort of cases and controls that includes patients diagnosed with early-stage HCC against a background of cirrhosis and cirrhotic patients without HCC (at risk) undergoing an established surveillance protocol.

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 Reach Training Protocol (BRTP). The BRTP 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 BRTP 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 BRTP's most immediate and salient metric is the limiting boundary of standing reach; and we hypothesize that expanding this boundary, as the BRTP 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 BRTP 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 BRTP 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 BRTP.

Background: While the intensive care of patients with life-threatening brain illnesses has advanced tremendously, a large number of therapies are still without proper scientific support. This can be partly explained by the fact that mechanisms of initial brain injury are still not well understood. Why additional neurological injury occurs during a patient's stay in the NeuroCritical Care Unit (NCCU) despite current best, evidence-based clinical practices, is also not well understood. However, over the past decade, better tools have become available to measure and monitor the impact of our clinical care on the rapidly changing physiology and chemistry of the injured brain. Some of these tools are CT, MRI, ultrasound, and catheter-based technology measuring blood flow and metabolism. These tools have enabled earlier detection of injury and complications and newer therapeutic strategies. Purpose: Examine disease pathways common to all brain injuries seen in the University of Maryland's 22-bed NCCU. Life-threatening neurological illnesses cared for in the NCCU include massive stroke, bleeding in and around the brain (subarachnoid hemorrhage, intracerebral hemorrhage, subdural hemorrhage, intraventricular hemorrhage), brain tumors, difficult to control seizures, neurologic infections, nerve and muscle diseases (such as myasthenia gravis or Guillain-Barre Syndrome), and spinal cord disorders among others. Many NCCU patients are comatose or paralyzed and may suffer injuries in other parts of the body as well. This effort will require the creation of a robust clinical database for the capture of data including patient characteristics (age, sex), clinical characteristics, medical treatments, surgical interventions, physiological data (such as vital signs, cerebral blood flow, intracranial pressure, cerebral oximetry, etc), laboratory data, and standard-of-care diagnostic studies such as electroencephalography (EEG), ultrasound, CT, MRI, and angiograms. Similar databases exist at other major centers for neurocritical care and have been instrumental to the identification of characteristics both predictive of and associated with outcomes of patients long after their stay in the NCCU. In addition, the samples collected will be included in the University of Maryland Medicine (UMM) Biorepository which is a shared resource to enable biomedical research by University of Maryland faculty.
