Background: Memory consolidation is the process by which memories become stable, long-term representations in the brain. Consolidation of a motor skill is dependent upon sleep. Some research shows that daytime naps improve people s motor performance and memory retention. Researchers want to find out how daytime naps may contribute to learning and support consolidation of motor skill memories. Objective: To learn the role of memory replay during wakeful rest and sleep (naps) in retaining a newly learned skill. Eligibility: English-speaking adults ages 18 and older with chronic stroke, or healthy, right-handed, English-speaking adults ages 18-35 and 50-80 Design: Participants will be screened with: - medical history - neurological history - medicine review - medical exam - neurological exam. Participants will have a magnetic resonance imaging (MRI) scan of the brain. For this, they will lie down in a scanner. The scanner makes loud noises, so they will wear earplugs. They will fill out an MRI screening form before each MRI. Participants will also have magnetoencephalography (MEG). MEG maps brain activity. It does this by recording the magnetic fields produced by naturally occurring electrical currents in the brain. For MEG, participants will lie down in the MEG room. Their eye movements may be recorded by a video camera. Participants will have behavior testing. They will practice typing random keys. Then they will repeatedly type a custom sequence that they see on a computer screen. Then they will take a 2-hour nap. Then they will type the same sequence again. Participants will have no more than 4 visits at the NIH over 3 months. Visits will last 2-4 hours each.

Eosinophils are a type of white blood cell. Elevated eosinophil levels can damage the heart, nerves, and other organs, in the syndrome known as hypereosinophilic syndrome (HES). Some individuals have a hereditary form of HES known as familial eosinophilia (FE). More research on the causation and mechanisms of HES is needed in order to design more effective and less toxic therapies. This study will investigate FE and its genetic causes, damage mechanisms, and disease markers (such as blood test abnormalities). It will enroll approximately 50 individuals (both adults and children) from a previously studied family with FE. This is a long-term study of indefinite duration. Participants will undergo yearly clinical examinations including medical history, physical examination, bloodwork, EKG, echocardiogram, and pulmonary function tests, with additional or more frequent examinations and tests as required. In addition, participants will donate blood and tissue for research purposes. Both adult and child participants will donate blood. At the initial evaluation, adult participants will donate bone marrow. During the study, some adult participants will also undergo a limited number of leukaopheresis sessions, in which blood is donated from one arm, the blood is separated into red blood cells and other components, and the red blood cells are returned into the donor's other arm. ...

Background: - People with human immunodeficiency virus (HIV) can sometimes develop thinking and memory problems. These problems can vary widely, from few symptoms to severe problems with memory and concentration. It initially was thought that good HIV treatment could prevent almost all HIV-related memory problems. However, even people with low HIV viral loads can have these problems. It may be caused by HIV affecting the brain and spinal fluid. It is not yet clear why HIV causes these problems and why they may be worse in some people than others. Researchers want to study people with HIV and healthy volunteers to see how HIV may affect people with only small amounts of the virus in their blood. Objectives: - To study thinking and memory problems in individuals with HIV that is otherwise controlled with medications. Eligibility: - Individuals between 18 of age or older whose HIV has been controlled with medications for at least 1 year. - Healthy volunteers between 18 of age or older. Design: - Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. A neurological test will also be given. Participants will have a baseline imaging study of the brain. - Within 12 weeks of the first visit, participants will have a second visit. Additional blood samples will be drawn. Another brain imaging study will be performed. - Within 8 weeks of the second visit, participants will have a third visit to collect more blood samples.

Background: Pituitary tumors can cause problems by secreting hormones in the body. They can also problems by growing large and pushing on organs near the pituitary gland. The best treatment for such tumors is to remove them by surgery. But that may be sometimes difficult. Some tumors maybe too small to see. Some other tumors maybe so large that portions maybe left behind during surgery. The endosphenoidal coil (ESC) is a new magnetic resonance imaging (MRI) device. It fits in a small space made during surgery near the pituitary. Researchers want to see if it helps transmit MRI signals during surgery to make better images of the pituitary gland and tumors. Objective: To test the safety of using a new coil device to improve MRI imaging of pituitary tumors during surgery. Eligibility: Adults 18-85 years old who are having pituitary tumor surgery at NIH Design: Participants will be screened with: - Medical history - Physical exam - Review of prior brain scans - Blood and pregnancy tests All participants will have MRI of pituitary gland. They will lie on a table that slides into a metal cylinder in a strong magnetic field. They will lie still and get earplugs for loud sounds. A dye will be inserted into an arm vein by needle. Participants will stay in the hospital for about 1 week. They will repeat screening tests. Participants will have standard pituitary surgery. They will get medicine to go to sleep. The surgeon will create a path to the pituitary gland from under the lip. During surgery, the ESC will be placed through the path to near the pituitary. Then an MRI will be done during surgery. Then the ESC will be removed and standard surgery will continue. Participants will get standard post-operative care under another protocol.

Background: Suicide is the second leading cause of death for young people ages 10-24 years. There is no gold standard for evaluating suicidal thoughts and behaviors in young people with autism spectrum disorder (ASD) or other neurodevelopmental disorders (NDD). Also, youth with ASD/NDD are often excluded from many research studies. Because of this, researchers need more data. They want to make sure they are asking the best questions for young people in clinics such as the National Institute of Mental Health (NIMH) clinic. They want to make sure they have the best data to determine if a person is at risk for hurting or killing himself or herself. Objective: To develop and assess the efficacy of a suicide screening tool for people with ASD/NDD. Eligibility: Youth ages 8 to 17 who are engaged in assessment or treatment at the NIMH for ASD or other NDD Design: Participants will fill out 4 questionnaires during a 1-hour meeting with study staff. They will answer questions about how they have been feeling. They will be asked if they think about or plan to hurt or kill themselves. They will also be asked if they have ever thought about it or planned it in the past. Other questions will assess their understanding of death. Participants can take a break if needed. Parents of the participants will be asked similar questions. Parents will be informed if their child has current thoughts of suicide. About 1 week after the initial assessment, parents will be contacted to fill out a follow-up questionnaire. It will take about 10 minutes to complete.

Background: - Radiation is a common treatment for prostate cancer. It helps damage tumor cells and causes them to die. Radiation can be effective, but some tumors may be harder to treat with radiation or even with surgery. This happens to a small number of men who have either radiation or surgery for prostate cancer. Most men who have these hard-to-treat tumors do not know if the tumor has recurred only in the prostate or has spread to another area. Also, men whose prostate cancer has recurred only after radiation may have different treatment options. This study will use improved imaging studies to better understand why some men do not respond as well to initial radiation treatments. Objectives: - To use detailed imaging studies to look at the results of local radiation therapy for prostate cancer. Eligibility: - Men at least 18 years of age who are scheduled to have radiation for prostate cancer. - Men at least 18 years of age whose prostate cancer has returned after earlier treatments. Design: - All participants will have a medical history and physical exam. Blood and urine samples will be collected. Imaging studies will be used to evaluate the cancer at the start of the study. - All participants will have an initial full magnetic resonance imaging (MRI) scan of the prostate. Tumor and healthy tissue samples will be collected. - Those whose cancer has recurred after treatment will discuss possible treatment options with the study doctors. - Participants who are scheduled to have radiation will have radiation therapy. This will be given according to the current standard of treatment. - After radiation, participants will have regular follow-up tests and imaging studies. They will have another full MRI scan 6 months after the end of radiation treatment.

This study will collect white blood cells and plasma for research on how the immune system controls HIV infection. The immune system of a very small group of HIV-infected patients, called non-progressors, has been able to control HIV for long periods without antiretroviral therapy. Some immune system-related genes important for this control have been identified in these patients. This study will examine the contribution of HLA genes B*57+, B*27+ and A*01+ to HIV disease in progressors and long-term non-progressors. (HLA type is a genetic marker of the immune system.) HIV-infected patients 18 years of age and older with HLA types B*57+, B*27+ and/or A*01+ may be eligible for this study. Participants will undergo apheresis-a method for collecting larger quantities of certain blood components than can safely be collected through a simple blood draw-by one of the following two methods: - Automated pheresis - Blood is drawn through a needle placed in an arm vein and spun in a machine, separating the blood components. The white cells are extracted and the red cells, with or without plasma (liquid part of the blood), are re-infused into the donor through the same needle or a needle in the other arm. An anticoagulant (medication to prevent blood from clotting) is usually added to the blood while in the machine to prevent it from clotting during processing. - Manual pheresis - One unit (1 pint) of blood is drawn through a needle placed in an arm vein, similar to donating a pint of whole blood. The red blood cells, with or without plasma, are separated from the rest of the blood and re-infused to the donor through the same needle. Manual pheresis will be done only when a person s estimated total blood volume or red cell count is too low to safely permit removal of blood through a pheresis machine. An adult small in size or markedly anemic, for example, may fall into this category. Some of the blood collected through apheresis may be stored for future studies of HIV disease and immune function and for HLA testing, a genetic test of markers of the immune system. Some of the blood may be used to screen for different types of viral liver infections, such as hepatitis A, B, C, D, E, F, or G. ...

The Metabolism, Infection and Immunity (MINI) Study is a longitudinal natural history study at the National Institutes of Health (NIH) that aims to define the relationship between infection, immunity and clinical decline in individuals with mitochondrial disease. Mitochondrial diseases are a group of disorders caused by problems with the cell s ability to produce energy. Infection in individuals with mitochondrial disease can lead to worsening clinical symptoms, particularly neurologic symptoms. Goals: The main goal of our study is to understand the relationship between infection and clinical decline in patients with mitochondrial disease. Mitochondrial diseases can affect many different parts of the body, including the immune system and its ability to respond to infection. Therefore, we perform a comprehensive evaluation of participants including a detailed immunologic assessment. We are not testing any new medicine or procedure to treat or cure IEM or mitochondrial diseases. However, by understanding the relationship between infection and mitochondrial disease, we hope to develop treatments in the future. At the NIH, we are interested in research. Although we do provide advice and care for people enrolled in our study, we are not able to take over the long-term care of participants. To enroll in our study, you (your child) must already have a confirmed diagnosis of a mitochondrial disease. We are not able to provide a "first time" diagnosis or regular metabolic care. What is involved? Once you contact our team members, you will be asked to provide medical records to determine eligibility. Our team will review the records and notify you if you (your child is) eligible to join the study. -Onsite participation: You (your child) will be invited to visit the National Institutes of Health in Bethesda, Maryland. This first visit will typically last 3-5 days. Depending on the level of participation, additional visits may be requested. Our team members will work with you and your child to coordinate the supports needed during your stay at NIH. Study participants may be seen in the clinic, day hospital or inpatient setting. When you (your child) arrive at the NIH we will have an informed consent discussion to confirm willingness to participate, answer questions and review the risks and benefits of the study. You (your child) will meet with a physician who will ask about medical and family history and do a physical exam (like in any doctor's office). We will ask all study participants to allow us to collect urine, draw blood, swab your (your child s) nose, and perform a detailed assessment. We may suggest additional evaluations or specialty consults for some participants based on clinical manifestations, age and level of independence. We will explain these studies to you (your child). They may include items such as- imaging studies, DEXA or MRI scan, energy expenditure or metabolic testing, developmental neuropsychological logical testing, physiatry, ophthalmology, or other consults. In some cases, we may request a skin biopsy (if one has not been done). You will receive the results of your (your child's) clinical testing and notes from any clinical consultations. -Remote participation: If you (your child) are unable to travel, you (your child) may be enrolled remotely for records review, questionnaires, and telethealth exams. Blood or other samples collection may be requested in coordination with local providers or lab testing companies

Background: The adrenal glands are 2 small organs that sit on top of each kidney. They release hormones; these are chemicals that control how the body works. Tumors on or outside the adrenal glands are called functional if they release hormones; they are called nonfunctional if they do not. Doctors who treat adrenal tumors need to know which type a person has. Researchers want to find better ways to learn whether an adrenal tumor is functional. Objective: To see if a new radioactive tracer ([68Ga]Ga-PentixaFor) can make it easier to identify functional adrenal tumors with positron emission tomography (PET) scans. Eligibility: People aged 18 years and older with 1 or more adrenal tumors. They must have increased levels of the hormones aldosterone or cortisol. They must also be enrolled in at least 1 other related NIH study (protocols 19-DK-0066, 18-CH-0031, or 09-C-0242). Design: Participants will be screened. They may have imaging scans. Their ability to perform normal activities will be reviewed. Participants will have one PET scan with the study tracer. The tracer will be given through a tube attached to a needle inserted into a vein. Participants will receive the tracer 1 hour before the scan. They will lie still on a bed while a machine captures images of the inside of their body. The scan will take 45 to 90 minutes. Participants heart rate, blood pressure, and rate of breathing will be checked before, during, and after the scan. Participants will have a follow-up visit 3 days after their scan. This visit can be by phone, email, or in person.

Background: Genetic testing called "sequencing" helps researchers look at DNA. Genes are made of DNA and are the instructions for our bodies to function. We all have thousands of genes. DNA variants are differences in genes between two people. We all have lots of variants. Most are harmless and some cause differences like blue or brown eyes. A few variants can cause health problems. Objective: To understand the genetics of immune disorders various health conditions, as well as outcomes of clinical genomics and genetic counseling services performed under this protocol. Eligibility: Participants in other NIH human subjects research protocols - either at the NIH Clinical Center (CC) or at Children s National Health System (CNHS) - (aged 0-99 years), and, in select cases, their biological relatives Design: Researchers will study participant s DNA extracted from blood, saliva, or another tissue sample, including previously collected samples we may have stored at the NIH. Researchers will look at participant s DNA in great detail. We are looking for differences in the DNA sequence or structure between participants and other people. Participants will receive results that: - Are important to their health - Have been confirmed in a clinical lab - Suggest that they could be at risk for serious disease that may affect your current or future medical management. Some genetic information we return to participants may be of uncertain importance. If genetic test results are unrelated to the participant s NIH evaluations, then we will not typically report: - Normal variants - Information about progressive, fatal conditions that have no effective treatment - Carrier status (conditions you don t have but could pass on) The samples and data will be saved for future research. Personal data will be kept as private as possible. If future studies need new information, participants may be contacted.
