Infections are a major cause of morbidity and mortality in patients undergoing hematopoietic stem cell transplant (HSCT). The purpose of this study is to evaluate if metagenomic next-generation sequencing (mNGS) can detect microbial signatures in people undergoing HSCT, and if microbial identification can be correlated with clinical features of infection (e.g., fever). Participants undergoing HSCT as part of other studies at the NIH Clinical Center (CC) will provide blood before the transplant and through 6 months after. Total nucleic acid will be extracted from plasma and subjected to mNGS. The primary objective of this study is to investigate if by using plasma and an mNGS approach, we can detect bacterial, fungal, protozoan, or viral DNA/RNA over time, in immunocompromised patients undergoing transplantation. Secondary objectives are to: (1) To correlate microbial identification with episodes of fever or clinical suspicion of infection; and to (2) correlate change in microbial signatures in patients with suspected immune reconstitution inflammatory syndrome. The study is conducted at the NIH Clinical Center. Participants, aged 3 years and older, on other research studies at the NIH CC who are undergoing HSCT are invited to take part of this study. Expected participation is up to six months.

Study rationale High risk patients with differentiated thyroid cancer (DTC) require therapy with 131 I under thyroid stimulating hormone (TSH) stimulation. There are two methods of TSH stimulation endogenous by thyroid hormone withdrawal (THW) leading to hypothyroidism and exogenous by injection of human recombinant TSH (rhTSH Thyrogen). The appropriate 131-I activity utilized for treatment is either based on empiric fixed dosage choice or individually determined activity based on 131 I dosimetric calculations. Although dosimetry utilizing radioactive iodine isotope 131 I enables calculation of maximum safe dose, it does not estimate the tumoricidal activity necessary to destroy the metastatic lesions. The alternative radioactive isotope of iodine -124 I, used for positron emission tomography (PET) imaging, might be used for calculation not only the maximum safe131 I dose, but also to predict the absorbed dose in the metastatic lesions. Study objectives The primary objective of this study is to compare the 124 I -PET/CT lesional and whole body dosimetry in each individual patient with metastatic radioiodine (RAI)-avid thyroid cancer under preparation with rhTSH and THW. The secondary objective is to evaluate the predicted by PET/CT lesional uptake with the early response to therapy. Study design This is a phase 2 pilot prospective cohort study comparing the lesional and whole body dosimetry within each patient undergoing exogenous (rhTSH) and endogenous (THW) TSH stimulation and followed for 5 years. Interventions Each study participant will undergo rhTSH and THW-aided 124 I-PET/CT dosimetric evaluations and will be subsequently treated with THW-aided RAI activity based on dosimetric calculations enabling maximum safe dosage. The patients will be followed in 12+/-3 months intervals for 5 years. Sample size and population This pilot study will include 30 patients with high risk differentiated thyroid cancer presenting with distant and/or loco-regional metastases.

This protocol will evaluate patients with systemic lupus erythematosus (SLE) and their relatives to learn more about how the disease develops and changes over time. It will also study genetic factors that make a person susceptible to SLE. Patients 3 years of age and older with known or suspected SLE and their relatives may be eligible for this study. Patients will be evaluated with a medical history and physical examination, blood and urine tests. Other procedures may include: 1. Electrocardiogram 2. 24-hour urine collection 3. Imaging studies, such as chest and joint X-rays, magnetic resonance imaging (MRI) scans, bone scans, and bone densitometry. 4. Questionnaire about the degree of disease activity, and survey of risk factors for disease complications. 5. Apheresis-Collection of plasma (fluid portion of blood) or blood cells for analysis. Whole blood is collected through a needle in an arm vein. The blood circulates through a machine that separates it into its components. The required component (plasma or cells) is removed and the rest of the blood is returned to the body through the same needle or through a second needle in the other arm. 6. Skin biopsy-Removal of a small skin sample for microscopic analysis. An area of skin is numbed with an anesthetic and a small circular portion (about 1/4 inch in diameter) is removed, using a sharp cookie cutter-type instrument. 7. Kidney, bone marrow or other organ biopsy-Removal of a small sample of organ tissue. These biopsies are done only if they can provide information useful in better understanding the disease or making treatment decisions. 8. Genetic studies-Collection of a blood sample for gene testing. Patients will be followed at least once a year with a brief history and physical examination and routine blood and urine tests. Some patients may be seen more often. Treatment recommendations will be offered to patients' physicians, and patients who are eligible for other research treatment studies will be invited to enroll. Participating relatives of patients will fill out a brief medical history questionnaire and provide a DNA sample (either a blood sample or tissue swab from the inside of the cheek) for genetic testing.

Pancreatic cancer is difficult to diagnose early. By the time people have been diagnosed, the cancer has usually spread to other parts of the body (metastatic). The standard treatment is chemotherapy, but other treatments are needed to improve outcomes in people with pancreatic cancer. The first treatment that people usually receive is chemotherapy. At the time this study started, some of the main standard chemotherapies for pancreatic cancer were mFOLFIRINOX or NALIRIFOX. Genes give your body instructions on how to make proteins. Proteins are needed to keep the body working properly. Many types of cancer are caused by changes in certain genes, making them faulty. Many people with pancreatic cancer have a faulty KRAS gene. One such change in the KRAS gene is called a G12D mutation. Researchers are looking for ways to stop the actions of abnormal proteins made from the KRAS G12D mutation. This study is about setidegrasib given with chemotherapy in people with pancreatic cancer who have the KRAS G12D mutation. Before setidegrasib can become an approved treatment, clinical studies need to be completed to understand how it works and how safe it is. The main aim is to learn if people who are given setidegrasib with chemotherapy live for longer than people who are given placebo with chemotherapy. Other aims are to learn if setidegrasib delays the cancer and symptoms returning, how the body processes setidegrasib, and its safety, when given with chemotherapy. People in this study will be adults with metastatic pancreatic cancer with the G12D mutation in their KRAS gene. Surgery or radiotherapy will not be an option to cure their cancer. People cannot take part if the cancer cells have spread to the thin tissue covering the brain and spinal cord (leptomeningeal disease), have symptoms of cancer in the brain or nervous system, or have recently had some other cancers that required treatment. In this study, people are given either setidegrasib with mFOLFIRINOX or NALIRIFOX chemotherapy, or a placebo with mFOLFIRINOX or NALIRIFOX chemotherapy. Whether people receive setidegrasib or placebo is decided by chance. The study doctor decides which chemotherapy (mFOLFIRINOX or NALIRIFOX) people receive. All of the study treatments are given slowly through a tube into a vein (infusion). People will continue to receive study treatment until their cancer gets worse, they can't tolerate the study treatment, they start other cancer treatment, they or the doctor decides the person should stop receiving study treatment, or sadly they pass away. There will be safety checks at each visit, and the doctors will continue to check for medical problems and people's wellbeing throughout the study.

Researchers are looking for more ways to treat PAH. In PAH, the blood vessels in the lungs become thick and narrow, which makes it harder for blood to flow. This causes high blood pressure in the lungs and overworks the heart. PAH can make it hard to breathe and be active. Some standard (usual) treatments for PAH can treat symptoms of PAH but do not stop PAH from getting worse. Sotatercept is a study medicine designed to treat PAH. It is a targeted therapy, which is a treatment that works on certain proteins that play a role in causing PAH. This is a long-term follow-up (LTFU) study. People who took part in certain other studies testing sotatercept for PAH may be able to join this study. The goal of this study is to learn about the long-term safety of sotatercept and if people tolerate it when taken with standard PAH treatment over a longer period of time.
