Adolescent Idiopathic Scoliosis (AIS) Gold Standard for Blood Loss
The purpose of this study is to establish a benchmark for measuring blood loss by directly measuring the change in red cell volume before and after surgery and to compare established blood loss estimators to this benchmark in order to determine the most accurate and precise method for estimating blood loss in adolescent idiopathic scoliosis surgery patients

Adolescent Idiopathic Scoliosis Outcomes Database Registry
The purpose of this study is to analyze the long-term outcomes of surgical treatment of idiopathic scoliosis of all curve patterns treated by either anterior or posterior procedures. In addition, to analyze the long-term outcomes of non-operative idiopathic scoliosis.

Adult and Juvenile Myositis
This study will evaluate subjects with adult- and childhood-onset myositis to learn more about their cause and the immune system changes and medical problems associated with them. Myositis is an inflammatory muscle disease that can damage muscles and other organs, resulting in significant disability. Children or adults with polymyositis or dermatomyositis or a related condition may be evaluated under this study. Healthy children or adults will also be enrolled as "controls," for comparison of test results. All patients will undergo a complete history (including completing some questionnaires) and physical examination, review of...

Advanced Materials Science in XLIF Study
This study is being conducted to evaluate the clinical and radiographic outcomes of three different interbody implant types when used with cancellous allograft chips with BMA or cellular allograft in patients undergoing XLIF surgery. The study will evaluate success by comparing the rate of fusion, complications profile, and any relationships between clinical outcomes (pain and function) and radiographic outcomes (fusion rate) between the three implant groups.

Advancing Understanding of Transportation Options
This Stage II randomized, controlled, longitudinal trial seeks to assess the acceptability, feasibility, and effects of a driving decision aid use among geriatric patients and providers. This multi-site trial will (1) test the driving decision aid (DDA) in improving decision making and quality (knowledge, decision conflict, values concordance and behavior intent); and (2) determine its effects on specific subpopulations of older drivers (stratified for cognitive function, decisional capacity, and attitudinally readiness for a mobility transition). The overarching hypotheses are that the DDA will help older adults make high-quality...

Aerobic Exercise in Women With Systemic Lupus Erythematosus
Background: As many as 1.5 million Americans are living with systemic lupus erythematosus (Lupus). Lupus makes people very tired. It also makes it hard for people to be physically active. Studies have shown that aerobic exercise training helps people with heart or lung illnesses be less tired and more active. Researchers want to use an exercise training program on people with Lupus to see if it has the same results. Objectives: To find out if aerobic exercise helps people with Lupus be less tired and more active. Eligibility: Women ages 21-80 who have Lupus and are not physically active. Design: Participants...

Alpha-Defensin and Synovial Proteins to Improve Detection of Pediatric Septic Arthritis
Differentiating between septic arthritis and other causes of joint inflammation in pediatric patients is challenging and of the utmost importance because septic arthritis requires surgical debridement as part of the treatment regimen. The current gold standard to diagnose septic arthritis in children is a positive synovial fluid culture; however, joint cultures may take several days to return. If a bacterial infection is present, it requires immediate surgical intervention in order to prevent lasting articular cartilage damage. Frequently surgeons must decide whether to surgically debride a joint before culture results are available. There...

Amnion-Based Injections in the Shoulder
Osteoarthritis (OA) of the shoulder is a common debilitating condition affecting up to 5% of the general population and as much as 32% of patients over 60 years of age. Clinically, OA is diagnosed by a combination of symptoms, such as slow onset of progressively worsening shoulder pain and stiffness over months to years (often with a history of minor trauma), and pain with activity. Physical exam may show tenderness and swelling, muscle atrophy, and decreased range of motion. Adhesive capsulitis (also called "Frozen Shoulder") is another common shoulder condition, affecting 2-5% of the general population. Frozen shoulder presents with a...
