Background: SARS-CoV-2 is the virus that causes COVID-19. Some people who recover from COVID-19 have symptoms that last long after the active infection ends. This is called long COVID. Sometimes, long COVID can affect the nerves and cause problems with sleep, thinking, the senses, and movement. Researchers want to find out whether people with long COVID have retained inactive remnants of SARS-CoV-2 in their bodies. Objective: To collect tissue samples to see if people with long COVID have remnants of SARS-CoV-2 in their bodies. Eligibility: People 18 years or older who have recovered from COVID-19, both with and without neurologic symptoms. Design: Participants will have 2 to 6 inpatient or outpatient visits over 4 months. Each visit will last 4 to 5 days. Participants will be screened to make sure it is safe to collect tissue samples from their body. They will have a physical and dental exam. They will have imaging scans and a test of their heart function. They will complete questionnaires about their health. They will give blood, urine, saliva, and stool samples. Their sense of taste and smell will be tested. Tissue samples will be taken from the digestive tract, lungs, colon, skin, muscle, lymph nodes, nasal passages, and mouth. Participants may be numbed or sedated for some of the procedures. Swabs will be used to collect cells from inside the mouth and nose. Participants will undergo lumbar puncture. A thin needle will be inserted into their lower back to draw out a sample of the fluid around their spinal cord. Participants will have follow-up phone calls after each clinic visit.

Background: Alcohol use disorder (AUD) affects about 29.5 million people in the United States. Only 3 medicines have been approved by Food and Drug Administration to treat AUD. Researchers want to find better treatments for AUD. Animal studies found that a medicine called spironolactone, may decrease the amount of alcohol the animals drank. Spironolactone is approved to treat high blood pressure, or heart failure in people. It is not approved to treat AUD. Objective: To test a medicine (spironolactone) in people who sometimes drink excessive alcohol in order to understand how the body breaks down spironolactone and if there are any side effects in people who drink alcohol while taking this medicine. Eligibility: People aged 21 and older with AUD. Design: Participants will have 4 separate 7-day stays at a clinic in Baltimore over 2 months. Spironolactone is a capsule you swallow. Participants will take a capsule twice a day for 5 days during each clinic stay. During 1 of their 4 stays, they will take a placebo instead of the medicine. The placebo capsule looks just like the spironolactone capsule but contains no medicine. Participants will not know when they are taking the medicine or the placebo. Participants will not drink alcohol until day 6 of each clinic stay. Then they will be asked to drink alcohol in a bar-like area in the clinic. Their breath and blood alcohol levels and their well-being will be measured. Participants will undergo other tests in the clinic: A DEXA (dual energy X-ray absorptiometry) scan uses X-rays to measure bone density and muscle mass. Participants will lie on an open-top, padded table, then a small arm will scan the full length of their body. The radiation participants will get in this study is about the same as from one regular x-ray. Blood tests. Participants may feel some discomfort at the site of needle entry. Electrocardiogram. This test records the heart activity. Sensors are attached to the skin with stickers and removed after a few minutes. Urine tests. All urine will be collected over a 3-day period during each stay. We will measure the amount of urine, and different hormones and salts in the urine. Questionnaires and tasks. Participants will answer questions about their alcohol use. They will perform tasks to test mood, craving, mental and physical coordination, and how much they feel an effect from alcohol after drinking.

Background: People have 4 parathyroid glands near the thyroid gland in the neck. Surgery is needed to remove a parathyroid gland that is too large or has a tumor. These glands can be in different places, so doctors use an imaging scan with contrast dye to help find them before surgery. Researchers want to know if a different type of scan and a new tracer can make it easier to find the tumors in the parathyroid glands. Objective: To see if PET/MRI and NeuroEXPLORER PET-CT scans with a 18F-FCH tracer are better than existing methods for finding the parathyroid glands. Eligibility: People aged 18 years or older who are scheduled for surgery to remove a parathyroid gland. Design: Participants will have up to 4 clinic or hospital visits. They will be screened. They will have a physical exam and give blood samples. Participants will have a 4-dimensional computed tomography (4D-CT) scan. This is the current way doctors look for parathyroid glands. They will be injected with an iodine-based dye for the 4D-CT scan. They will lie on a padded table that slides into a donut-shaped machine. Participants will have a positron emission tomography (PET)-magnetic resonance imaging (MRI) and NeuroEXPLORER PET-CT scan. For these scans, they will be injected with a radioactive tracer (18F-FCH). They will wait about 30 to 60 minutes for their body to absorb the tracer. They will lie on a padded table that slides into a tube. Their vital signs will be monitored during the scan. Participants will have surgery to remove the target gland. They may need to stay in the hospital for up to 3 nights. Participants will have a follow-up visit 6 months after the surgery. This may be done remotely....

Background: - Coccidioidomycosis is caused by a fungus that grows in the southwest United States and parts of Mexico and South America. This disease is caused by breathing dust containing the fungus. It can lead to serious lung and breathing problems. Rarely, the fungus can infect other body parts. This is called disseminated coccidioidomycosis (DCM). If the fungus stays in the lungs for more than 6 months, it is called refractory coccidioidomycosis (RCM). People with DCM or RCM may have difficulty fighting off infection because of immune system problems. Researchers want to study the immune systems of people with DCM or RCM, to learn more about the disease and the best ways to treat it. They also want to learn more about the types of people that get DCM or RCM and about the fungus that causes it. Objectives: - To learn more about DCM and RCM, the fungus that causes these diseases, and the people who get them. Eligibility: - People over age 2 with DCM or RCM. Design: - Participants will be screened with a review of their medical records. - At the initial visit, participants will have: - Medical history and physical exam - Blood and urine tests. Some blood may be used for genetic testing. The samples will not include participants names. Participants will be notified only if the tests show something urgent about their DCM/RCM. Researchers think this sort of problem will be rare. - Questionnaire about their DCM/RCM - Sputum (mucus) collection. They will spit into a cup. - Participants will have 1 follow-up visit per year. They will have blood tests. They may have other procedures to treat their DCM/RCM.

This study will collect biological samples for use in research experiments aimed at better understanding the clinical features of certain diseases. The specimens may be used to evaluate the effectiveness of known therapies, refine treatment approaches, identify potential new therapies, and explore opportunities for disease prevention. The following individuals 2 years of age or older may be eligible for this study: - Patients with a cancerous solid tumor or a cancerous or non-cancerous blood disorder who are being screened for or who are enrolled in a treatment study at the NIH Clinical Center - HLA-compatible donor family members (18 years of age or older) of the above patients who are being evaluated for or are enrolled in an NIH study as a stem cell transplant donor - Patients with a cancerous solid tumor or a cancerous or non-cancerous blood disorder or a bone marrow failure condition who cannot participate in an NIH treatment protocol or travel to the NIH Clinical Center and who are referred for participation through their home health care provider. Research samples will be collected from participants when blood is drawn or bone marrow, urine, or stool is collected, or tumor or other tissue is biopsied as part of their general medical care. Investigators may periodically request an additional sample of blood, stool, or urine. Participants who are 18 years of age or older may donate a large number of white blood cells through a procedure called leukapheresis. This procedure is not part of general medical care and would be done for research purposes only. For apheresis, a catheter (plastic tube) is placed in a vein in the subject's arm. Blood flows from the vein into a cell separator machine, where the white cells are separated from the red cells, platelets, and plasma by a spinning process. The white cells are removed and collected, and the rest of the blood is returned to the subject through a second tube placed in the other arm.

This protocol is designed to provide a mechanism for the Department of Transfusion Medicine, Clinical Center to collect and process blood components from paid, healthy volunteer donors for distribution to NIH intramural investigators and FDA researchers for in vitro laboratory use. Donors meeting research donor eligibility criteria will be recruited to donate blood and blood components by standard phlebotomy and apheresis techniques. The investigational nature of the studies in which their blood will be used, and the risks and discomforts of the donation process will be carefully explained to the donors, and a signed informed consent document will be obtained. Donors will be compensated according to an established schedule based on the duration and discomfort of the donation. NIH and FDA investigators requesting blood components for research use will be required to submit an electronic (Web-based) memo of request, briefly describing the nature of the research, and providing assurance that samples provided through this protocol will be used solely for in vitro and not for in vivo research. This protocol also provides a detailed schema for careful and frequent laboratory safety monitoring of repeat research apheresis donors. Blood components for research use will be distributed with a unique product number, and the DTM principal and associate investigators will serve as the custodians of the code that links the product with a donor s identity. The nature of the in vitro studies in which the blood and components collected in this study will be used is not the subject of this protocol, and is not possible to describe, since it involves basic investigative efforts in greater than 170 different NIH and FDA laboratories. The intent of this protocol is not to approve the research itself, but to provide adequate and complete informed consent for the donor, and to assure that the education, counseling, and protection of the study subjects (research blood donors) is performed in accordance with IRB, OHSR, OPRR and other applicable Federal regulatory standards
