The target population of this project is older people with high risks of falls. About 30% community-dwelling individuals over 65 years of age fall each year and the rate of fall related injuries leading to loss of function and independence increases with age. Falls are the leading cause of fatal and non-fatal injuries and the leading cause traumatic brain injury in older adults. Slip-related falls in older adults comprise 40% of outdoor falls and are the leading cause of hip fracture or traumatic head injury. In 2012, 2.4 million non-fatal falls were treated in emergency room visits with $30 billion dollars spent on direct medical costs. In addition to fractures and traumatic brain injury, nonfatal falls frequently lead to reduced levels of activity, fear of falling, and reduced quality of life. Clearly, advancing the predictive, preventative, and rehabilitative methods aimed at reducing the risk of injurious falls in this population is imperative. Although falls are multi-factorial in nature, there has been few individualized assessment of the biomechanical causes of falls. The purpose of this study is to conduct subject-specific training on older adults with fall risks with combined home-hospital rehabilitation. This project will involve rehabilitation interventions based on the characteristics of falling patterns and older adults with reduced capability controlling the balance. To conduct subject-specific fall prevention training. based on identified individual fall mechanisms.

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.

Fractures of the lower leg are especially difficult for older adults. They are more likely to have serious complications, require longer healing times, and have a higher risk of death This occurs because their bodies cannot tolerate stress as well as younger individuals. The injury itself places significant strain on the body, and surgery adds additional stress. Anesthesiologists use nerve blocks to help manage pain during and after these injuries. A nerve block is an injection that numbs the fracture and surgery area by blocking pain signals. These injections help patients need fewer opioid medications. However, new research shows these nerve blocks may provide benefits beyond pain management. Studies looking at older adults with hip fractures who received nerve blocks showed better overall outcomes: fewer deaths, fewer serious complications, and shorter hospital stays. However, it is not currently known if nerve blocks work this well for other broken bones in the leg, like in the thigh or shin. Additional research is need to know if nerve blocks can help patients with all types of leg fractures recover faster and experience fewer problems. Before the investigators start a large clinical trial, a small pilot study needs to be completed to determine if a larger clinical trial is feasible. This pilot study will evaluate the ability to recruit enough patients, ensure patients can receive the assigned treatment, collect data effectively, follow the study protocol, and track participants over time. The results will indicate whether the investigators are prepared to proceed with a full-scale trial and help refine the approach.

The PHA Registry (PHAR) is a national study about people who have pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH). PHAR collects information from people with PAH and CTEPH who are cared for in participating PHA-accredited Pulmonary Hypertension Care Centers throughout the U.S. PHAR will determine how people with PAH and CTEPH are evaluated, tested, and treated, and will observe how well these participants do. The goal is to see if people with PH are treated according to recommended guidelines, and to see if there are certain factors that can lead to better or worse outcomes. PHAR will include information about people with PAH and CTEPH in the U.S. who are seen at participating PHA-accredited PH Care Centers. PHAR contains data about patient care and outcomes. Specifically, data in the PHAR includes information on diagnosis; clinical status; socioeconomic status; diagnosis test results; body size; treatment information; interest in participating in clinical trials; family health and social history; and information about smoking, alcohol, or drug use. Participants are followed over time, and provide updates such as changes in therapy, how often participants need to go to the hospital, and survival. Such information may help healthcare providers provide better care.

Management of ACLF is mainly supportive. The poor outcomes lead physicians to consider liver transplantation as an option, even if controversial. In sicker recipients, LT results in immediate survival, but poor medium-term survival rates in some studies. The scarcity of deceased donors obliges to maximize LT success. Alternative strategies, as living-donor LT, should be explored. LDLT has impressive results in Eastern centers, but it is restrained in Western countries, due to potential life-threatening complications in the donor.

This is a Phase III clinical randomized control trial to investigate differences between patient with an infected nonunion treated by PO vs. IV antibiotics. The study population will be 250 patients, 18 years or older, being treated for infected nonunion after internal fixation of a fracture with a segmental defect less than one centimeter. Patients will be randomly assigned to either the treatment (group 1) PO antibiotics for 6 weeks or the control group (group 2) IV antibiotics for 6 weeks. The primary hypothesis is that the effectiveness of oral antibiotic therapy is equivalent to traditional intravenous antibiotic therapy for the treatment of infected nonunion after fracture internal fixation, when such therapy is combined with appropriate surgical management. Clinical effectiveness will be measured as the primary outcome as the number of secondary re-admissions related to injury and secondary outcomes of treatment failure (re-infection, nonunion, antibiotic complications) within the first one year of follow-up, as defined by specified criteria and determined by a blinded data assessment panel. In addition, treatment compliance, the cost of treatment, the number of surgeries required, the type and incidence of complications, and the duration of hospitalization will be measured.
