For most cancers, long-term follow-up is the best measure of treatment effectiveness. The Department of Radiation Medicine at Loma Linda University Medical Center operates the James M. Slater, M.D., Proton Treatment and Research Center, the world's first hospital-based proton tre…

This trial will study the reconstruction of the anterior part of the mandible and the adjacent soft tissue parts by a mandibular prosthesis made in porous titanium, associated or not, to a latissimus dorsi or pectoral flap, to avoid reconstruction with free microanastomosed bone …

Thoracic surgery via posterolateral thoracotomy causes significant postoperative pain. There are several methods of postoperative pain relief, including intravenous analgesics and local-regional analgesia techniques. Although thoracic epidural remains the gold standard, it is no…

This is a prospective in vitro cell biology study of polymorphonuclear leukocyte (PMN) protein synthesis in response to PAF. PMNs from cord blood of premature human infants at risk for NEC (birth weight between 501 - 1500 grams) and PMNs from cord blood of healthy term infants wi…

Background: The NCI Surgery Branch has developed experimental therapies that involve taking white blood cells from patients' tumor or from their blood, growing them in the laboratory in large numbers, and then giving the cells back to the patient. Objective: This study will co…

The anticoagulant effect of warfarin varies greatly among individuals. Some of this variability is attributed to differences in the activity of CYP2C9, the predominant enzyme involved in the metabolism of S-warfarin. The present study is designed to define the differences in war…

The PROMISSE Study is an observational study of 700 pregnant patients, enrolled at nine major clinical centers. The purpose of the study is 1) to determine whether certain proteins (called complement split products) that can injure healthy organs can be used to predict poor pregn…

To evaluate the accuracy of ischemic preconditioning (IPC) as a protective maneuver against ischemia/reperfusion lesion in patients undergoing major liver resection with intermittent portal triad Clamping (IPTC). Summary Background Data: For sake of safety and to avoid excessive…

Chronic kidney disease (CKD) is a silent epidemic affecting more than 37 million Americans. The burden of morbidity and mortality associated with CKD derives from its frequent progression to end-stage kidney disease (ESKD) and the disproportionate risk of cardiovascular disease (…

This study will explore how genes may influence the severity of ankylosing spondylitis, a form of arthritis that affects the spine. Patients have inflammation of the joints of the spine, which may cause the bones of the spine to fuse, resulting in difficulty performing daily acti…

IMPAACT P1026s is a Phase IV prospective clinical study to evaluate the pharmacokinetics (PKs) of antiretroviral (ARV) and tuberculosis (TB) medications in pregnant women and their infants. (Pharmacokinetics are the various interactions between a drug and the body.) This study al…

The investigators are doing the research to discover genes that cause Inflammatory Bowel Disease (IBD) specifically in the African American population. African Americans with or without Crohn's disease or ulcerative colitis are eligible to join. If you agree to join the study, th…

Purpose: The purpose of this protocol is 1. To comprehensively evaluate patients with autoinflammatory diseases clinically, genetically and immunologically at the autoinflammatory disease clinic at the NIH. 2. To follow patients with autoinflammatory Diseases that are geneticall…

RATIONALE: Adjuvant therapy given after surgery for early breast cancer may cause infertility. Assessing young women's attitudes and feelings about the risk of infertility may help improve the ability to plan effective treatment. PURPOSE: This clinical trial is studying young wo…

This study will examine families in which one sibling of a sibling pair, or twin pair, has developed a systemic rheumatic disease and one has not, to see if and how the two differ in the following: * Blood cell metabolism; * Types of cells in the blood; * Environmental exposures…

This study will use magnetic resonance imaging (MRI) and ultrasound images to study how muscles, tendons, and bones work together to cause motion. The procedure is one of several tools being developed to characterize normal and impaired musculoskeletal function, with the goal of …

Osteopenia and osteoporosis are increasingly reported in HIV-infected patients, and appear to be more frequent than in general population. However, pathogenesis remains unclear, and published studies still give non concordant results. We therefore started a prospective study, to…
