Background: - The immune system is made up of special cells, tissues, and organs that fight infections. Problems with this system may lead to frequent, severe, or unusual fungal infections. These infections are often difficult to treat. Researchers want to collect blood and tissue samples from people who have unusual, persistent or severe fungal infections or immune problems that increase the risk of these infections. Objectives: - To collect medical information and samples for a long-term study of people with immune system problems that lead to fungal infections. Eligibility: - People with a history of fungal infections caused by immune system problems. - Parents, children, and siblings of this group. - Healthy volunteers not related to the first two groups. Design: - This long-term study may last for up to 25 years. Those in the study may need to provide new information about every 6 months. The procedures for each person may vary with the particular diagnosis and the extent of fungal infection. Healthy volunteers may have only one or two visits. - At the first visit, those in the study will have a full medical history and physical exam. They will also provide blood. - Research procedures may include the following: - Saliva, urine or stool testing - Mouthwash collection for DNA testing - Collection of cheek cells, nail clippings, or vaginal fluid - Tests of leftover tissue or body fluid from previous medical procedures - Skin or oral mucous membrane biopsy - Collection of white blood cells - Followup visits will involve a physical exam and updated medical history. Blood, saliva, urine, or nail clipping samples may be taken for ongoing studies. Any additional tests or exams required by the study doctors may also be done. - Participants may withdraw from the study pool at any time.

This study will explore the causes of rheumatic diseases and why many of them affect certain minority communities more severely. Rheumatic diseases may cause joint pain, stiffness or swelling. Some can involve bones, muscles, tendons or ligaments. Some cause abnormalities of the immune system-the body s defense against disease. Some rheumatic diseases are painful or deforming and some can be life threatening. Information obtained from this study will be used to learn about the disparities in rheumatic disease in the minority community and to design further, more targeted, research studies to address this issue. Patients with known or suspected rheumatic disease 18 years of age or older may be eligible for this study. Candidates will undergo a medical history and physical examination to confirm the diagnosis of rheumatic disease and determine what is needed for evaluation and treatment. Participants will receive standard medical care for rheumatic disease and arthritis. No experimental treatments, medications or procedures will be included in this study. Procedures may include routine blood tests for blood chemistries, cell counts, and antibodies commonly found in patients with rheumatic disease; a urine test for proteins and cells; and X-rays and other imaging tests to check for abnormalities in the lungs or other organs. All medical information will be kept confidential. Patients who are found to be eligible for other current NIH research studies will be offered an opportunity to participate in these studies.

This 24-month study is testing whether adding AdiaVita, an umbilical cord blood-derived stem cell and exosome product, to glutathione therapy helps improve autism symptoms in children ages 3-12 more than glutathione alone. Children will be randomly placed into one of two groups for the first three months: one group receives glutathione only, and the other receives glutathione plus monthly intravenous AdiaVita infusions. Both groups also use topical glutathione cream twice daily at home. Autism symptoms will be tracked over two years using the Autism Treatment Evaluation Checklist (ATEC) filled out by parents and by therapists or teachers. Safety, side effects, quality of life, and overall well-being will be closely monitored through regular clinic visits, physical exams, blood tests, and adverse event reporting. After the initial three-month phase, children who received glutathione alone may cross over to receive AdiaVita infusions at no additional cost if safety checks at month 6 are satisfactory. Approximately 100 children with a confirmed autism diagnosis from the Central Florida area will take part. Participation is completely voluntary, and families may withdraw at any time.

The goal of this clinical trial is to learn if a health system intervention called "Stratified Targeted Engagement from Primary Care to Physical Therapy (STEPPT)" can improve how often doctors refer Hispanic patients with spine pain to physical therapy (referral rate) and how often patients attend physical therapy after being referred (adherence rate). The main questions this study aims to answer are 1) does STEPPT improve physical therapy referral and adherence rates compared to usual care for Hispanic patients with spine pain who seek care in a Federally Qualified Health Center (FQHC) serving low income communities, and 2) how consistently do FQHC providers and staff deliver STEPPT to patients who may benefit? STEPPT will train doctors and other health care providers to educate participants on the benefits of physical therapy for spine pain and participants will receive culturally tailored handouts and videos to teach them about their spine pain and what to expect in physical therapy. Patients will also receive personalized assistance to schedule their physical therapy appointment and address potential barriers for attending the appointment.

The goal of this study is to compare two different ways of dosing cefepime, an antibiotic for very sick patients - the usual approach to dosing or a new dosing method. The new dosing method uses only doses that are available in normal care, but choosing between the different doses is based on more information about the patient's body including their kidney function. The primary purpose of this study is to test how easy it is for healthcare professionals to use the new dosing method and how best to conduct the trial. The study will also assess if the new dosing method helps patients recover faster and reduces side effects.

Hidradenitis Suppurativa (HS) is a skin condition that causes deep, painful bumps on the skin. These bumps usually appear in an area where the skin rubs together. They start as small bumps but may become swollen and red over time. If they fill with pus, these lumps are called abscesses; these can also burst. Over time, the area can get scars and tunnels on or under the skin. Recent studies suggest that the condition may start when hair follicles become damaged and blocked. This impacts the skin and may activate the body's germ-fighting (immune) system. This allows bacteria to grow on the skin which worsens the condition and can cause abscesses. The main aims of this study are to learn how safe zasocitinib is, how well it works and how well adults with HS tolerate it compared with a placebo. The participants will receive the study treatment (either zasocitinib or placebo) for up to 4 months (16 weeks). The placebo looks like the zasocitinib capsule but does not have any medicine in it. After the first 4 months, all participants (also those who initially received placebo) will then receive zasocitinib for up to 8 months (36 weeks). During the study, participants will visit their study clinic 12 times.

This study is researching an experimental drug called pozelimab (called "study drug"). The study is focused on people with a condition where certain parts of the eye's retina stop working over time, which can make it harder to see. This is called geographic atrophy (GA). The aim of the study is to see how safe and tolerable the study drug is when used as an injection in the eye. The study is looking at several other research questions, including: - What side effects may happen from taking the study drug - How much study drug is in the blood and the fluid in the eye at different times - Whether the body makes antibodies against the study drug (which could make the drug less effective or could lead to side effects)

TAK-188 is a new medicine that targets a protein called CCR8, which is found on the surface of certain cells (Tregs) inside tumors. These cells can weaken the body's ability to fight cancer. TAK-188 may help to remove these Tregs. Removing these Tregs may allow more cancer-fighting cells (CD8+ T cells) to attack the tumor and potentially stop tumors from growing. In this study, researchers want to learn if TAK-188 can help the body's immune system better fight cancer in adults with advanced cancers which have not gotten better with regular treatments. The main aims of this study are to check if TAK-188 is safe in adults with advanced or spreading (metastatic) solid tumors, if participants tolerate the treatment with TAK-188 and to learn if TAK-188 works well in adults with certain advanced cancers after their previous treatments didn't work. Participants may receive TAK-188 for up to 1 year. Their health will be monitored after the treatment has ended for up to another year.
