Inflammatory or degenerative diseases of the brain and spinal cord, such as multiple sclerosis, may be related to problems with an individual s immune system. However, more information is needed on the ways in which the cells of the immune system interact with the central nervous system (CNS). This study will compare tests performed on both healthy volunteers and individuals who have signs or symptoms of immune-related damage to their CNS. This study will include two groups of subjects at least 12 years old. Subjects will either have symptoms of immune-related CNS damage, or will be healthy volunteers selected for comparison purposes. Study participants will visit the NIH Clinical Center on an outpatient basis for an initial evaluation visit. During the visit, patients will provide a comprehensive medical history and undergo a neurological examination, and will provide blood samples for research purposes. The healthy volunteers will be asked to schedule a return visit for a magnetic resonance imaging (MRI) procedure, and may be asked to undergo other tests requested by the study researchers on an as-needed basis. The group of patients with symptoms of immune-related CNS damage will be asked to undergo a series of tests, including the following: - MRI procedures, with a minimum of three brain MRIs and one spinal cord MRI taken approximately 4 weeks apart - A diagnostic lumbar puncture, performed on an outpatient basis - Tests of brain and vision activity - Additional blood and tissue samples Patients with symptoms of immune-related CNS damage may be offered the opportunity to participate in additional followup tests with NIH researchers.

The purposes of this study are to 1) identify the genes responsible for certain immune disorders, 2) learn about the medical problems they cause, and 3) learn how to predict who is likely to develop these disorders and what the risk is of passing them on to children. The immune system is the body s defense system. Some immune deficiencies impair a person s ability to fight infections; others render a person susceptible to allergies, or to autoimmune diseases such as lupus or arthritis, in which the immune cells (white blood cells) attack and destroy the body s own tissues. Patients with immune disorders known or suspected to have a genetic basis and their family members may enroll in this study. Eligibility will be determined by a review of the patient s medical records and family medical history. Participants will provide a small blood sample for genetic (DNA) and white blood cell analysis. Gene samples (but not white blood cells) may also be obtained by mouth brushing or skin biopsy. For the mouth brushing, a small brush is rubbed against the inside of the cheeks for 1 minute to wipe off some cells. For the skin biopsy, a small circle of skin (about 1/8 inch) is removed under local anesthetic. Pregnant women may be asked to provide a fetal sample (amniotic fluid cells or chorionic villus sample). All samples will be used for immune or genetic studies of the family s immune disorder. If test results show a specific genetic variation responsible for the family s immune disorder, a report will be sent to the patient s doctor or genetic counselor, who will discuss the implications for the family. NIH researchers and genetic counselors will also be available to explain results and answer questions. Information will not be available in the case of disorders that cannot yet be linked to a specific genetic abnormality. Information from this study will increase knowledge about the immune system and what causes immune deficiencies. Participants may also learn the underlying cause of an immune disorder that affects them or someone in their family information may be useful in guiding treatment and in making decisions regarding family planning....

Preterm infants often have difficulty learning how to feed by mouth because the coordination of sucking, swallowing, and breathing develops later in pregnancy. Delays in achieving full oral feeding can prolong hospitalization and increase the need for tube feeding. This study evaluated whether a Pacifier-Activated Lullaby (PAL) system could improve oral feeding performance in preterm infants. The PAL device plays a recorded maternal or caregiver voice when an infant generates an adequate non-nutritive suck on a pacifier, providing positive reinforcement during feeding development. In this randomized controlled trial conducted at Nemours Children's Hospital in Orlando, Florida, preterm infants who were transitioning from tube feeding to oral feeding were assigned either to receive PAL therapy in addition to standard feeding care or to receive standard feeding care alone. Researchers compared measures of oral feeding performance, feeding efficiency, growth, and progression toward independent oral feeding between the two groups. The goal of the study was to determine whether reinforcing non-nutritive sucking with auditory feedback could enhance feeding development and improve clinical outcomes in preterm infants. The information gained from this study may help clinicians better understand the role of music-assisted feeding interventions in neonatal care and identify which infants are most likely to benefit from this approach.

In this study, the investigators will determine (a) whether metabolism (secretion and turnover) of glucagon is altered in patients with PBH, (b) whether this is affected by a meal, (c) whether PBH affects the ability of the body to produce glucose (endogenous glucose production), and (d) whether PBH affects the amount of glycogen in the liver (storage form of glucose) when fasting and after a meal. The investigators will determine the effect of glucagon to raise glucose levels after a meal. To answer these questions, participants will receive an infusion of a stable (nonradioactive) isotope of glucose and glucagon, and a meal containing a stable isotope of glucose. Glycogen will be measured by magnetic resonance imaging (MRI) of the liver before and after the meal. This information will be used to develop computer models for the glucagon pump system.

This Phase 1, open-label study will evaluate two investigational radiopharmaceuticals in adults with selected advanced or metastatic solid tumors. SKL35502 is an imaging agent used with SPECT scans to identify tumors with neurotensin receptor 1 (NTSR1), a protein found on some cancer cells, and to assess where the agent travels in the body and the radiation dose delivered to tissues. Participants with sufficient SKL35502 tumor uptake may receive SKL35501, a treatment designed to deliver targeted alpha radiation to NTSR1-expressing tumor cells. Part A will evaluate the safety and imaging performance of SKL35502 and the safety, tolerability, pharmacokinetics, biodistribution, dosimetry, and biologically active dose range of SKL35501, as well as preliminary antitumor activity. Part B will further evaluate selected SKL35501 dose levels, including randomized low- and high-dose groups in participants with colorectal cancer, and will expand evaluation in selected tumor types. The study will also examine relationships among SKL35502 imaging, NTSR1 expression, SKL35501 tumor uptake, and treatment outcomes.

WorkoutCPP is a pilot study evaluating the feasibility of a personalized exercise recommendation system for individuals with chronic pelvic pain disorders (CPPDs). The study uses reinforcement learning (RL), a type of artificial intelligence that adapts recommendations over time based on each participant's reported pain levels, symptom burden, and exercise compliance. Participants receive daily exercise recommendations that alternate between standard, non-personalized guidance and personalized, RL-generated recommendations across four 2-week phases, allowing within-person comparison of outcomes under each condition. The primary hypothesis is that an RL-based adaptive recommendation system is feasible to deliver in a CPPD population.

Previous research on the osteopathic manual technique entitled "Pedal Pump" has shown health benefits, specifically increasing lymphatic flow, decreasing lower extremity edema, and decreasing serum lactic acid after maximal exercise. However, due to the limitation of human practitioners, research has been limited. The Pedal Pump is now a device which facilitates consistency in treatment and allows for increased sample size in research. This clinical trial studies the effects of 10 minutes of Pedal Pump treatment for hospitalized patients with lower extremity edema, almost the same as Pedal Pump Clinical Trial on Edema V1 that is underway; however, this study focuses primarily on the objective data gathered by trained Occupational Therapists who regularly measure lower extremities. Key Question for this second study: Is the Pedal Pump a feasible treatment for hospitalized patients? Secondary question: Does the Pedal Pump decrease lower extremity edema? This is a novel idea in its early stage of development, so Investigators anticipate product advancements, further testing with larger population sizes, and future publications.
