Background: Sickle cell disease can often be treated with blood stem cell transplants. But for some people the disease returns. This study will give a second transplant to people whose disease has returned but still have some donor cells in their body. Objective: To cure people s sickle cell disease by giving a second treatment that makes more room in their bone marrow for donor cells. Eligibility: People ages 4 and older with sickle cell disease who had a transplant but the disease returned, and their donor relatives. Donors can be 2 years of age or older. Design: Participants will be screened with medical history, physical exam, and blood tests. Recipients will also be screened with heart and breathing tests, x-rays, a bone marrow sample, and teeth and eye exams. They must have a caregiver. Donors will have 7-8 visits. They will take a drug for 5-6 days to prepare them for the donation. For the donation, blood is taken from a vein in the arm or groin. The stem cells are collected. The rest of the blood is returned. This may be repeated. Recipients will get a long IV line in their arm or chest for about 1-2 months. They will take drugs to help their body accept the donor cells. They will get the donor cells and red blood cell transfusions through the line. They will stay in the hospital about 30 days after the transfusion of donor cells. In first 3 months after the infusion, recipients will have many visits. Then they will have visits every 6 months to 1 year for 5 years. During those visits they will repeat some of the screening tests....

Background: - Spondyloarthritis (SpA) is a group of bone and joint disorders that may cause back and joint pain and stiffness. In some cases, SpA can lead to abnormal bone growth affecting the joints and spine. Some patients have SpA without ever developing these growths, while others develop them after only a few years. Researchers are interested in studying people with SpA and their relatives to determine which people are more likely to develop more severe conditions. Objectives: - To identify symptoms and medical tests that can help determine whether a person with SpA is at risk for developing more severe forms of the disease. Eligibility: - Individuals of any age who have been diagnosed with SpA. - Healthy volunteer relatives (at least 6 years of age) of the individuals with SpA. Design: - Participants will be screened with medical records and family medical histories, and will be invited to the clinical center for the study. - Participants with SpA will have a physical exam and medical history, including a study of joint movement, blood and urine tests, and questionnaires about pain and quality of life. - Participants with SpA will have imaging studies, including magnetic resonance imaging (MRI).

Many individuals with severe motor impairments rely on Assistive Technologies (ATs) or Brain-Computer Interfaces (BCIs) to interact with digital devices such as their computers. Clinicians and researchers currently lack a common framework to objectively quantify how much a given AT or BCI improves real-world function or to compare across tools. This project seeks to address this gap by developing a standardized method to objectively assess or compare the functional benefit of these tools on digital independence, i.e., the ability to independently operate computers, phones, and other digital systems, by creating a unique Digital Assessment Interface (DAI). This assessment will be a simulation of online and digital activities that prior work has determined is important to functional daily living in the digital domain. Participants will complete this assessment with various ATs and BCIs, and these scores will be used to create an index, which will be comprised of performance outcomes, clinician-reported outcomes, and patient-reported outcomes. The tool aims to quantify and compare digital task performance across devices and user populations. The primary objective of this study is to develop an index. The index will quantify functional performance of individuals using various ATs and BCIs. The secondary objectives are to extensively evaluate the psychometric properties of the index, such as the validity, responsiveness, reliability, and floor/ceiling effects both globally and across different devices and impairment levels, ensuring that it can reliably measure the impact of an AT or BCI on a user's ability to independently operate digital systems; and to characterize the familiarization and use of specific BCI and AT systems with reference to a normative healthy control population.

In order to systematically improve code status communication and documentation while clarifying how providers understand code status decisions, we propose the Choice of Diction's Effect Electronic Measures of Resuscitation Study Inpatient (CODE-EMRS.I) with 3 aims: Aim 1 - Determine rate of patient utilization of code status invitation (research) via the Portal (Hypothesis 1: Participants with an existing Portal are more likely to participate in research than new signups); Aim 2 - Evaluate different phrasings in code status prompts with and without death language (Hypothesis 2: Participants are more likely to pick no code with death language than without); Aim 3 - Determine how objective data drives physician agreement on code status decision (Hypothesis 3: Physicians are more likely to disagree with full code decisions for poor GO-FAR, but not CCI). Participants will fill out all study questionnaires electronically, but have options within these to ask to speak to a study physician/their own physician for clarification. After completing the surveys, the research associate will deliver the patient's code status decision to the attending of record and ask their views on it. Once a week, participants who have expressed interest in the study (by clicking the "I am interested" button) but have not completed the study will receive a reminder to complete the study as well as an offer to withdraw from the study in that same communication.

This is a pilot clinical study designed to evaluate the effects of a dietary supplement on selected blood-based nutritional biomarkers in healthy children aged 4 to 15 years. Approximately 24 children will be screened and enrolled to account for potential dropouts, with a target of 20 participants completing the study. Eligible participants will attend a screening and baseline visit, followed by daily intake of the study supplement for 4 weeks. After the supplementation period, participants will return to the clinic for an end-of-study visit. Blood samples will be collected at baseline and after 4 weeks to measure nutritional biomarkers, including vitamin D, vitamin B12, folate, omega-3 fatty acids, and standard blood count parameters. Additional assessments include height, weight, body mass index (BMI), and a socioeconomic questionnaire. Throughout the study, participants or their caregivers will record daily supplement intake, any medications taken, and any adverse events in a study diary. The results of this pilot study will provide preliminary data on the effects of the dietary supplement on serum biomarkers in children.

A universal challenge in clinical investigation of novel therapeutics is the need for quantitative, objective biomarkers that directly address the mechanisms of disease and provide information relevant to clinically meaningful functional improvement. This has been a particular challenge in rare and slowly progressive diseases such as Duchenne Muscular Dystrophy (DMD). The investigators hypothesize that urinary N-terminal fragment of titin (NTFT) corresponding to activity level/intensity will define a high-precision, non-invasive biomarker of systemic muscle injury to enable serial measurements of efficacy and safety in the clinical investigation of gene therapy for DMD and other myopathies. This should provide a valuable exploratory, secondary and eventually primary outcome measure of therapeutic efficacy to minimize the enrollment size in informative early phase and pivotal clinical trials.

This clinical trial studies the side effects of image-guidance and online adaptation with stereotactic body radiation therapy (SBRT) for the treatment of patients with prostate adenocarcinoma that has not spread to other parts of the body (localized). Image-guided SBRT is a standard treatment for localized prostate cancer. This treatment uses imaging of the cancer within the body to define and localize the area to be treated with the radiation. Imaging can be obtained using either computed tomography (CT), magnetic resonance imaging (MRI), or a combination of the two. Typically, with SBRT, a radiation plan is developed based on the CT or MRI images obtained before treatment begins and adjustments are not made to the plan during treatment. However, anatomy can be different from day-to-day which may cause radiation to be delivered to the normal surrounding structures and possibly more side effects. During image-guided SBRT with online adaptation, the initial radiation plan is designed similarly; however, when the patient presents for radiation, the attending radiation oncologist, a dosimetrist, and a medical physicist "re-optimize" the radiation plan using the current anatomy of the day, meaning the changes in bladder and prostate size/shape are taken into account. The initial plan and the re-optimized plan are then compared, and the plan that has the optimal balance between delivering a tumor killing dose of radiation and minimizing radiation dose to normal surrounding structures is delivered. Image-guidance and online adaptation with SBRT may lower side effects and be a safer way to treat localized prostate adenocarcinoma.

Researchers are looking for new ways to treat HIV-1 (Human Immunodeficiency Virus Type 1). The usual (standard) treatment for HIV-1 is antiretroviral therapy (ART), which includes taking medicines to lower the amount of HIV-1 in the body. Standard ART helps people live longer, but people must take up to 3 medicines up to twice a day. Standard ART may also cause other health problems. Researchers want to know if a study ART works as well as a standard ART to treat HIV-1. The study ART combines 2 medicines, islatravir and ulonivirine, and is taken once a week. The goals of this study are to learn: 1) If the study ART works as well as a standard ART to treat HIV-1, and 2) About the safety of the study ART and if people tolerate it compared to a standard ART.
