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.

Background: Blood cancers (such as leukemias or lymphomas) often do not respond to standard treatments. A transplant of blood stem cells from a healthy donor can help people with these cancers. Sometimes these transplants cause serious side effects, including a common immunologic problem called graft-versus-host disease. A drug called cyclophosphamide given early after the transplant (post-transplantation cyclophosphamide, PTCy) can reduce these complications. But sometimes this drug has its own negative effects. Furthermore, studies in mice suggest that an intermediate, rather than very high, dose of this drug may best protect against graft-versus-host disease. Objective: To find out if a lower dose of PTCy is more helpful for people who undergo blood stem cell transplants. Eligibility: People aged 18 and older who have a blood cancer and are eligible for a transplant of blood stem cells from another person. Healthy donors are also needed but must be related to the individual needing the transplant. Design: Participants will undergo screening. Transplant recipients will have imaging scans and tests of their heart and lung function. They will be assessed for the status of their cancer, including bone marrow taken from their pelvis and possibly also scans and/or fluid drawn from the spine depending on the disease type. Donors will be screened for general health. They will give several tubes of blood. They will give an oral swab and saliva and stool samples for research. Recipients will be in the hospital at least 4 to 6 weeks. They will have a temporary catheter inserted into a vein in the chest or neck. Medications will be given and blood will be drawn through the catheter. The transplanted stem cells will be given through the catheter. Participants will receive medications both before and after the transplant. Participants will return to the clinic at least once a week for 3 months after leaving the hospital. Follow-up visits will continue periodically for 5 years.

Background: After an allogeneic hematopoietic stem cell transplant (HSCT), the donor genome is found in the recipient s circulation and tissues. Post-HSCT recipients may receive a medication in which the dosing needs to be adjusted based on genetic variation. While genes in donor genome may influence dosing and administration of some agents, the majority of established gene-drug pairs in pharmacogenetics are related to expression of metabolic or transporting enzymes located in recipients tissues, often the liver. Determining which genetic variants influence drug disposition in HSCT recipients is complicated by chimerism in samples that are routinely collected for determining genotype. However, chimerism in tissues is poorly studied in this patient population. Objectives: To determine the most reliable host genomic source for pharmacogenetic testing in participants that have received allogeneic HSCT. Eligibility: People ages 18 years and older who are enrolled on a clinical trial at the NIH Clinical Center under which they will donate or receive an allogeneic HSCT. Design: DNA is collected prior to HSCT and for two years after HSCT. Blood will be collected and skin fibroblast cell lines will be established prior to HSCT to serve as a reference genome. Blood, buccal cells, skin, and hair will be monitored for the development of mixed chimerism via detection of short tandem repeats. Liver biopsies will be collected from participants undergoing hepatic surgery. Pharmacoscan arrays will be conducted to determine which samples are useful for pharmacogenetic testing in participants who receive allogeneic HSCT. A probe drug cocktail will be administered pre- and post-HSCT to determine if transplantation alters the metabolic phenotype of liver enzymes. ...

Background: Chronic heavy drinking can cause alcohol use disorder (AUD). AUD changes how the brain works. People with AUD may drink compulsively or feel like they cannot control their alcohol use. Acamprosate is an FDA-approved drug that reduces anxiety and craving in some, but not all, people with AUD. Objective: To learn more about how acamprosate affects brain function in people with AUD. Eligibility: People aged 21 to 65 years with moderate to severe AUD. Design: Participants will stay in the clinic for 21 days after a detoxification period of approximately 7 days. Acamprosate is a capsule taken by mouth. Half of participants will take this drug 3 times a day with meals. The other half will take a placebo. The placebo looks like the study drug but does not contain any medicine. Participants will not know which capsules they are taking. Participants will have a procedure called electroencephalography (EEG): A gel will be applied to certain locations on their scalp, and a snug cap will be placed on their head. The cap has sensors with wires. The sensors detect electrical activity in the brain. Participants will lie still and perform 2 tasks: they will look at different shapes and press a button when they see a specific one; and they will listen to tones and press dedicated buttons when they hear the corresponding tones. Participants will have 2 EEGs: 1 on day 2 and 1 on day 23 of their study participation. They may opt to have up to 4 more EEG studies (one on day 13 and one on each of the three follow-up visits) and 2 sleep studies, in which they would have sensors attached to their scalp while they sleep. Participants may have up to three follow-up visits for 6 months.

Background: For adolescent and young adults (AYAs) with certain life-threatening illnesses, hematopoietic stem cell transplant (HSCT) provides the best chance for cure and survival. HSCT is a life-saving therapy, but this treatment also comes with significant risks. Given these risks, it is imperative that patients and their families have the opportunity to share their values, priorities, and goals through advance care planning (ACP) to ensure that the care they receive through the transplant process remains patient-centered. Despite the benefits of ACP discussions, many barriers, including provider discomfort, may prevent these conversations with AYAs. Objective: To see if AYAs who undergo HSCT and their caregivers benefit from discussing ACP topics. Eligibility: People aged 18 to 39 years enrolled in an NIH study with a planned HSCT. One caregiver aged 18 years or older will also be invited to participate. Design: Participants will complete a 20-minute questionnaire. They will be asked about the priorities they have related to their care and their prior experiences with ACP. Participants will have 3 conversations with a study team member over 4 to 9 weeks. Each talk will last 45 to 60 minutes. First, participants will talk about their upcoming transplant and their expectations. They will also be asked about their fears and worries and will discuss what is most important to them in terms of support, comfort, their values, and their goals. Next, they will learn about Voicing My CHOiCES . This guide gives people a place to say what kind of care they want to receive during their treatment and includes a place to document how they would want to be cared for if they can no longer make decisions on their own. Participants will be guided as they fill in a few pages from this guide. The third conversation will review the first talks. Participants may ask questions and review any topic. They will complete follow-up questionnaires and be provided with a summary of their care priorities revealed in the discussions. They will be asked about their experience participating in this study, and their comfort with ACP discussions. They will be asked what they think of the meaningfulness, timing, and cultural sensitivity of these talks....

Background: Eosinophilic esophagitis (EoE) is a disease that causes inflammation in the esophagus. The esophagus is the tube that moves food from the mouth to the stomach. Diagnosing EoE currently requires a specialized tool called an endoscope. The esophageal string test (EST) is another test; the EST collects fluid from the upper digestive tract. An EST is simpler and cheaper than an endoscopy. Researchers want to know if an EST can diagnose EoE. Objective: To test if the EST can diagnose EoE in people who have trouble swallowing. Eligibility: Adults aged 18 to 65 years with trouble swallowing. They must have been born in Africa and be of African descent. Design: Participants will be screened. They will give blood, stool, urine, and skin swab samples. They will complete surveys about their medical history, diet, symptoms, and home environment. They will bring a sample of their drinking water for testing. Participants will have an EST. They will swallow a pill capsule that contains a nylon string. One end of the string will be taped to their cheek. The string will unravel down the esophagus and into the stomach. It will be pulled out after 1 hour. Fluids that soaked into the string will be tested. At a different visit, participants will have an endoscopic exam. An endoscope is a flexible tube that is inserted down the mouth; it can be used to take tissue samples from the esophagus, stomach, and small intestine. Participants will have a final visit in person, online, or by phone. They will take a survey and talk about their test results.

Methylmalonic acidemia (MMA), one of the most common inborn errors of organic acid metabolism, is heterogeneous in etiology and clinical manifestations. Affected patients with cblA, cblB and mut classes of MMA are medically fragile and can suffer from complications such as metabolic stroke or infarction of the basal ganglia, pancreatitis, end stage renal failure, growth impairment, osteoporosis, and developmental delay. The frequency of these complications and their precipitants remain undefined. Furthermore, current treatment protocol outcomes have continued to demonstrate substantial morbidity and mortality in the patient population. Increasingly, solid organ transplantation (liver, and/or kidney) has been used to treat patients. Disordered transport and intracellular metabolism of vitamin B12 produces a distinct group of disorders that feature methylmalonic acidemia as well as (hyper)homocysteinemia. These conditions are named after the corresponding cellular complementation class - (cblC, cblD, cblF, cblJ and cblX) - and are also heterogenous, clinically and biochemically. The genetic disorders underlying cblE and cblG feature an isolated impairment of the activity of methionine synthase, a critical enzyme involved in the conversion of homocysteine to methionine and these disorders feature (hyper)homocysteinemia. Lastly, a group of patients can have increased methylmalonic acid and/or homocysteine in the blood or urine caused by variant(s) in recently identified (ACSF3) and unknown genes. In this protocol, we will clinically evaluate patients with methylmalonic acidemia and cobalamin metabolic defects. Routine inpatient admissions will last up to 4-5 days and involve urine collection, blood drawing, ophthalmological examination, radiological procedures, MRI/MRS, skin biopsies in some, and developmental testing. In a subset of patients who have or will receive renal, hepato- or hepato-renal transplants or have an unusual variant or clinical course and have MMA, a lumbar puncture to examine CSF metabolites will be performed. In this small group of patients, CSF metabolite monitoring may be used to adjust therapy. The study objectives will be to further delineate the spectrum of phenotypes and characterize the natural history of these enzymopathies, query for genotype/enzymatic/phenotype correlations, search for new genetic causes of methylmalonic acidemia and/or homocysteinemia, identify new disease biomarkers and define clinical outcome parameters for future clinical trials. The population will consist of participants previously evaluated at NIH, physician referrals, and families directed to the study from clinicaltrials.gov as well as the Organic Acidemia Association, Homocystinuria Network America and other national and international support groups. Most participants will be evaluated only at the NIH Clinical Center. However, if the NIH team decides that a patient under the age of 2 years is a candidate subject for this research protocol, that patient may enroll at the Children's National Medical Center (CNMC) site, pending approval by Dr Chapman, the Principal Investigator of the CNMC location Individuals may also enroll in the tissue collection only part of the study at the UPMC Children's Hospital of Pittsburgh or share medical history and clinical data via telemedicine visits remotely. Outcome measures will largely be descriptive and encompass correlations between clinical, biochemical and molecular parameters.

Bottom gender affirming surgery is one of the key steps towards aligning the physical appearance and gender identity in transgender women. This surgery not only helps in reducing gender dysphoria but also significantly improves the quality of life and psychological well-being of the patients. The basic steps of bottom surgery typically involve the creation of a vagina using the skin from genital organs like the testes and penis, construction of the clitoris and labia. This complex surgery aims to create a functional and aesthetically pleasing vaginal canal that allows for sexual activity, urinary function, and a natural appearance. As part of routine care, a special graft (skin-like material) called Kerecis™ is used to line the middle part of the vagina. It is made from North Atlantic cod skin that is treated in the laboratory and made suitable for surgery purposes. It can be used instead of skin. This graft has been given permission by the Food and Drug Administration (FDA) for marketing the US. This study aims to identify changes in healing parameters following Kerecis™ based vaginoplasty. Up to 20 participants for this study. Participants will be asked to fill out study questionnaires during follow-up visits at post-op week 2, week 12, month , and year 1. At the 6 month post-op follow up, punch biopsies will be obtained from the deepest part, middle part, and the vaginal part most near to the vaginal opening parts to check the healing process using a microscope. The punch biopsies will be 1/8th inch x 1/8th inch each.

This investigator-initiated, prospective study evaluates the diagnostic utility of rhPSMA-7.3 (¹⁸F) PET/CT (flotufolastat F18, marketed as POSLUMA®) in men with biopsy-proven, low-risk or favorable intermediate-risk prostate cancer managed with active surveillance. The study aims to determine whether the addition of PSMA-based PET/CT to standard multiparametric MRI (mpMRI) improves detection of clinically significant prostate cancer compared to MRI alone. Eligible participants will undergo rhPSMA-7.3 (¹⁸F) PET/CT and mpMRI prior to confirmatory prostate biopsy. Biopsies will target areas identified on MRI, PET/CT, or both, and histopathologic outcomes will serve as the reference standard. The study will assess lesion-level concordance between PET/CT, MRI, and pathology, and evaluate the predictive value of PET/CT for disease upgrading. Approximately 120 participants will be enrolled at Mount Sinai Hospital over 12 months. Study participation will involve one imaging visit, one confirmatory biopsy, and follow-up through review of clinical results. There is minimal risk to participants beyond standard diagnostic procedures. The study is funded jointly by the Icahn School of Medicine at Mount Sinai and Blue Earth Diagnostics, which provides the imaging agent flotufolastat F18 and technical support.

Nearly 50% of the adult workforce experience adverse psychological symptoms (e.g., stress, depression, burnout, etc.) stemming from workplace stressors, with healthcare workers experiencing rates as high as 80%. Some common complaints and downstream consequences of working in high-stress healthcare occupations are elevated levels of perceived stress, depression, and burnout. These conditions have been associated with unfavorable occupational (e.g., increased medical errors), patient (e.g., increased mortality rates), and provider-related outcomes (e.g., increased rates of cardiovascular disease), imposing a heavy burden on an already stretched system. Given the impact of perceived stress, depression, and burnout on employee and patient health, a clear need exists to develop effective interventions to reduce distress and promote well-being among healthcare professionals. In particular, interventions that target processes particularly vulnerable to provider stress (e.g., compassion) are needed. The present study will evaluate the feasibility and efficacy of a mindfulness-based intervention inspired by the Buddhist Four Immeasurables practice on reducing perceived stress (primary outcome), depressive symptoms, burnout, and biological markers of inflammation, and enhancing psychological well-being and sleep quality (secondary outcomes) in 80 healthcare workers. Additionally, we will investigate several mediators (compassion, positive emotions, equanimity, and mindfulness) of intervention effects. Participants will be healthcare employees of UCLA Health. They will be enrolled in a six-week, two-arm randomized controlled trial. Participants will complete self-report questionnaires at baseline, mid-course, and post-intervention to assess study outcomes and mediators. We aim to advance the study of interventions that reduce distress and promote well-being using practices that cultivate kind feelings toward oneself and others.
