This study will provide follow-up evaluation and care of patients who have undergone allogeneic (donor) stem cell transplantation at the NIH Clinical Center. Patients are monitored for their response to treatment, disease relapse, and later-occurring effects of the transplant. Patients between 10 and 80 years of age who received a donor stem cell transplant at the NIH Clinical Center under an NHLBI protocol may be eligible for this study. Candidates must have had their first transplant at least 3 years before entering the current study. Participants are generally seen in the clinic every 12 months for some or all of the following procedures: - Periodic physical examinations, eye examinations, and blood and urine tests. - Bone marrow aspiration and biopsy: A sample of bone marrow is obtained for microscopic examination. The patient is given local anesthesia or conscious sedation. An area of the hipbone is numbed, a thin needle is inserted through the skin into the bone, and a small amount of marrow is withdrawn. - Tissue biopsy: A small piece of tissue or tumor is obtained for microscopic examination. Depending on the site of the biopsy, the tissue may be removed using a cookie cutter-like "punch" instrument, a needle, or a knife. The area is numbed and the tissue is removed with the appropriate tool. - Imaging tests to visualize organs, tissues, and cellular activity in specific tissues. For these tests, the patient lies on a table that slides into the scanner. They may include the following: 1. Nuclear scans use a sensitive camera to track a small amount of radioactive material (radioisotope) that is given to the patient by mouth or through a vein. The scan may show abnormal areas of tissue in the bones, liver, spleen, kidney, brain, thyroid, or spine. 2. Magnetic resonance imaging (MRI) uses a magnetic field and radio waves to examine small sections of body organs and tissues. 3. Computerized tomography (CT) uses x-rays and can be done from different angles to provide a 3-dimensional view of tissues and organs. 4. Positron emission tomography (PET) uses a fluid with a radioisotope attached to it to show cellular activity in specific tissues. The fluid is given through a vein and travels to the cells that are most active (like cancer cells), showing if there is an actively growing tumor. - Pulmonary (lung) function tests: The patient breathes into a machine that measures the volume of air the person can move into and out of the lungs. - Heart function tests may include the following: 1. Electrocardiogram (EKG) evaluates the electrical activity of the heart. Electrodes placed on the chest transmit information from the heart to a machine. 2. Echocardiogram (Echo) is an ultrasound test that uses sound waves to create an image of the heart and examine the function of the heart chambers and valves. 3. Multiple gated acquisition scan (MUGA) is a nuclear medicine test that uses a small amount of radioactive chemical injected into a vein. A special scanner creates an image of the heart for examining the beating motion of the muscle. Disease relapse or progression, or transplant-related problems may be treated with standard medical, radiation, or surgical therapy, or patients may be offered experimental therapy.

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.

Background: Blood pressure is one of the key markers of cardiovascular health. High blood pressure, also called hypertension, can increase the risk of heart disease or stroke. Monitoring a person s blood pressure continuously over a 24-hour period at home is the best way to diagnose hypertension, but the equipment currently used to do it is cumbersome. This natural history study will test a new technique for monitoring blood pressure continuously over time. Objective: To test a new technique (speckle plethysmography) for measuring blood pressure in healthy adults. Eligibility: Healthy people aged 18 years and older. Design: Participants will come to the clinic a minimum of 2 times. The screening visit will last up to 2 hours. Participants will have a physical exam. Their vital signs will be taken. The clinical visit will last up to 1 hour. Participants will recline in a chair. Sensors to measure the activity of the heart will be placed on their chest. Different sensors will be placed on two fingers and one big toe. A device to measure blood pressure will be placed on one arm. While wearing the sensors, participants will undergo 3 tests: They will be asked to breathe slowly for 2 minutes. They will be asked to solve a math problem. They will immerse one hand or foot into an ice bath for up to 2 minutes. Each test will be followed by a 5-minute recovery period. Participants may elect to return for up to 3 more visits during the following week.

Background: This study follows people who have had, or will soon have, a transplant using stem cells from another person. This is known as an allogeneic hematopoietic stem cell transplant (HSCT). Graft-versus-host disease (cGVHD) can happen after HSCT. cGVHD can cause mouth problems and more serious issues. Researchers want to study changes in the mouth that might indicate cGVHD. Objective: To identify cGVHD in the mouth and better understand the development, treatment, and progress of post-transplant changes in the mouth. Eligibility: Adults at least 18 years old who will soon undergo HSCT or have had one in the past 3 years Healthy adults at least 18 years old Design: All participants will have a screening visit and baseline visit. They will last 60-90 minutes. Over these two visits, participants will have: Medical and dental history Dental exam. Questions about their eating habits and general health Blood drawn through a needle in the arm Vital signs taken Pictures of their mouth and lips taken Questions about their oral health, including about pain, sensitivity, or dryness Saliva samples taken. Participants will spit into a sterile plastic tube. Swabs taken of the mouth and some of the saliva, plaque, and fluid from the spaces between teeth and gums. Participants may also have: A piece of skin taken (biopsy) from the inner lining of the cheeks A piece of skin taken (biopsy) from the lower lip Dental X-rays Urine pregnancy test Most participants will have at least 7 study visits over 3 years. They will meet with a dentist and repeat baseline tests.

Objectives: The overall study objective is to compare the sensitivities and specificities of morphometric analysis techniques using structural MRI images based on pre- and postsurgical localization of epileptic foci in patients undergoing presurgical evaluation for medically refractory epilepsy. To carry out these analyses, we aim to establish an age-stratified normative imaging database using healthy volunteers. Additional objectives are to identify abnormal networks in these patients using resting state fMRI/EEG and MEG/EEG, and to use language and memory fMRI tasks to examine the effects of epileptogenic zones and surgery on cognitive function and the networks associated with these functions. Study population: 300 adults and children (age 8 and older) with uncontrolled focal epilepsy, and 200 age-stratified healthy volunteers. Design: A retrospective and prospective natural history study. Research procedures for patients in this study include neuropsychological testing and 1-4 MRI sessions during presurgical evaluation and an additional 1-3 MRI sessions and neuropsychological testing approximately 12 months post-operatively. Research testing (such as research neuropsychological tests or MRI scanning sequences) will be done during a visit for clinical testing whenever possible, likely reducing the number of required visits. Patients will also have optional MEG and 7T structural imaging. Data will also be obtained from patients who have already undergone epilepsy surgery if they had procedures as outlined in the protocol and are willing to share the data. Healthy volunteers will receive a subset of the pre-operative procedures for patients, requiring at least 3 visits. In order to ensure adequate data acquisition, subjects may be re-scanned up to three times for the portions of the study in which they participated, possibly requiring additional visits. Outcome measures: The main outcomes will be establishment of normative values for morphometric analysis methods in age-stratified normal controls, and comparison of the sensitivity and specificity of these measures to pre- and postsurgical localization of the epileptogenic zone. Secondary outcome measures will include determination of the sensitivity and specificity of source localization using MEG/EEG and resting state fMRI/EEG, and to evaluate changes in activation during rest, as well as language and memory fMRI tasks in patients pre- and postsurgically, to examine the effects of epileptogenic zones and surgery on cognitive function and the networks underlying these functions.

Background: Lymphoma is a type of blood cancer. Blood cell transplant can cure some people with lymphoma. Researchers want to see if they can limit the complications transplant can cause. Objective: To test if a stem cell transplant can cure or control lymphoma. Also to test if new ways of getting a recipient ready for a transplant may result in fewer problems and side effects. Eligibility: Recipients: People ages 12 and older with peripheral T cell lymphoma that does not respond to standard treatments Donors: Healthy people ages 18 and older whose relative has lymphoma Design: Participants will be screened with: Physical exam Blood and urine tests Bone marrow biopsy: A needle inserted into the participant s hip bone will remove marrow. Donors will also be screened with: X-rays Recipients will also be screened with: Lying in scanners that take pictures of the body Tumor sample Donors may donate blood. They will take daily shots for 5 7 days. They will have apheresis: A machine will take blood from one arm and take out their stem cells. The blood will be returned into the other arm. Recipients will be hospitalized at least 2 weeks before transplant. They will get a catheter: A plastic tube will be inserted into a vein in the neck or upper chest. They will get antibody therapy or chemotherapy. Recipients will get the transplant through their catheter. Recipients will stay in the hospital several weeks after transplant. They will get blood transfusions. They will take drugs including chemotherapy for about 2 months. Recipients will have visits 6, 12, 18, 24 months after transplant, then once a year for 5 years.

Background: Chordoma is a rare, slow growing, often fatal bone cancer derived from remnants of the embryonic notochord. It occurs mostly in the axial skeleton (skull base, vertebrae, sacrum and coccyx), is more frequent in males than females, and has a median age at diagnosis of 58.5 years, with a wide age range. This typically sporadic tumor is often advanced at presentation, and mortality is high due to local recurrence or distant metastases. The usual treatment is surgery, followed by adjuvant radiation therapy. Chemotherapy has not had a significant treatment role. Reports of a small number of families worldwide with two or more relatives with chordoma support a role for susceptibility genes in chordoma etiology. Recently we determined that duplications of the T gene co-segregated with disease in four multiplex chordoma families. The T gene encodes brachyury, a tissue-specific transcription factor that is expressed in notochord cells and is essential for formation and maintenance of the notochord. Some of the other chordoma families that we studied did not have T-gene duplications; the aggregation of chordomas in these families may result from changes in other susceptibility genes or other types of mutations targeting the T gene. We are continuing gene identification studies of multiplex chordoma families at the NIH Clinical Center under protocol 78-C-0039. We also want to determine whether alterations in any identified chordoma susceptibility genes are associated with sporadic chordoma in the general population. Objectives: The major goal of this protocol is to identify sporadic chordoma patients willing to provide germline and tumor DNA for studies to determine the frequency of alterations in chordoma susceptibility genes. Our previous protocols with SEER and Massachusetts General Hospital to identify chordoma patients were limited to residents of specific geographic regions in the U.S. (2 states and 2 metropolitan areas) or to patients with pediatric skull base tumors. This protocol will enroll patients who more broadly represent the age, site and gender distributions of sporadic chordoma in the general U.S. population. Eligibility: Eligible patients are males and females in the U.S. with chordoma diagnosed at any age and at any primary site. Because we want to obtain saliva from all participants, eligibility is limited to patients who will be greater than or equal to age 6 years at the time of enrollment. Design: The study description and contacting information including an e-mail link to the study contact person will be posted on web sites of two chordoma support groups. We will mail study information to be given to patients to colleagues at major medical centers that treat chordoma. The components of the study will be carried out in subjects' homes using materials mailed to them. Up to 100 participants will: 1) complete a self-administered Personal and Family Medical History Questionnaire, 2) collect saliva using a saliva collection kit, and 3) provide permission to obtain medical/pathology records, and paraffin blocks or slides on each primary chordoma. Parents will serve as proxies for minor children. We will recontact patients who report chordoma in at least one blood relative. If we confirm the relative's chordoma diagnosis, we will invite the study subject and selected family members to participate in clinical and gene mapping studies under protocol 78-C-0039. We may also recontact study participants to tell them about any new studies on chordoma etiology. They can decide at that time whether they want to participate in them. ...

Mechanical ventilation is a commonly used life-saving hospital procedure for patients with severe breathing difficulty. Some patients have difficulty separating from the ventilator and need to be removed gradually. This process is called ventilator weaning. It is not known what is the best way to wean patients from the ventilator. In this study, the investigators will compare two commonly used ventilator weaning strategies and compare their success. One ventilator strategy, the Pressure Support Ventilation weaning (PSV), combines 12 hours ventilator weaning with 12 hours rest on the ventilator. This strategy is faster with an anticipated weaning in 2 weeks. The other strategy, the Therapist implemented Patient Specific weaning (TIPS), gradually lowers support and weans in 3 weeks. Patients admitted to Barlow Respiratory Hospital (BRH) for ventilator weaning will be asked to participate in this study within 72 hours of hospital admission. Participants will undergo a spontaneous breathing trial (SBT) to assess your ability to breathe while receiving minimal or no ventilator support. Patients who pass SBT will be eligible for cool aerosol trials (humidified, oxygenated air without positive pressure mechanical ventilation). Participants who fail SBT within 24 hours will be eligible for the study. Participants will be randomized to receive PSV or TIPS ventilator weaning. The investigators will collect clinical, laboratory and mechanical ventilator information throughout the study period. Ventilator weaning success will be compared at day 30. The study will not interfere with any components of clinical care but the study investigators will be allowed to change the ventilator weaning strategy from PSV to TIPS, if a participant is unable to tolerate PSV weaning.

The goal of this study is to examine the impact of a diet high in fresh lean pork, compared to a plant-based diet, on cardiovascular function and vasomotor symptoms in perimenopausal women with overweight and obesity. The main questions it aims to answer are: 1. How does a diet high in pork, compared to a plant-based diet, affects blood lipids, endothelial function, and blood pressure? 2. How does a diet high in pork, compared to a plant-based diet, affects blood nitrate, cardiometabolic biomarkers, inflammatory biomarkers, and vasomotor symptoms? Researchers will compare the diet high in pork to a plant-based diet to see if pork helps improve cardiovascular and mesopause symptoms. Participants will: - Consume both of the diets, each for 4 weeks, with a washout period between 2 and 6 weeks in between the diets trials - Visit the clinic 5 times with weekly meal pick ups during the diet trials - Undergo testing procedures including: weight and body composition, blood pressure and pulse, endothelial function using ultrasound of upper arm, microvascular blood flow, blood draws, physical activity measurements, and questionnaires.

Rationale: LTI-03 is an experimental medication breathed into the lungs using an inhaler. It is being studied for the treatment of Idiopathic Pulmonary Fibrosis (IPF). IPF is a progressive, fatal lung disease caused by the death of lung cells involved in oxygen uptake and by progressive fibrosis (scarring) of the lungs. As the disease progresses, patients experience loss of lung function and increased breathing problems. LTI-03 is hypothesized to treat IPF by protecting and restoring the function of the oxygen uptake cells and by controlling lung fibrosis which may result in improving lung scarring. The purpose of this research is to evaluate LTI-03 including: its safety, whether it causes side effects, whether it improves lung scarring, and whether it improves IPF symptoms. LTI-03 will be compared to placebo in patients diagnosed with IPF within the last 5 years. Patients on a stable dose of nintedanib, pirfenidone, or nerandomilast (if available by prescription) may participate. Trial Design: This is a Phase 2, randomized, double-blind, placebo-controlled, multi-center study that includes a 28-day Screening Period, a 24-week Treatment Period, and 4-week Follow-up Period. Study Assessments: Up to 9 visits to the study clinic will be required. Safety and tolerability will be evaluated with the following assessments: physical examination; collection of vital sign data (heart rate, blood pressure, respiratory rate and peripheral oxygen saturation [SpO2] via pulse oximetry); heart data collected by 12-lead electrocardiogram; and collection of blood samples for safety laboratory tests. In addition, participants will be asked about any adverse events (side effects) they have experienced between clinic visits, if they have changed any medications, and if they are able to properly use their study drug inhaler. Participants will undergo a lung function test (spirometry) at every visit, which will be used to evaluate both safety and efficacy. Another test measuring the diffusion capacity of the lungs for carbon monoxide (DLCO) will be required at Screening only. Blood samples will also be collected at each visit to measure disease biomarkers. At select visits patients will be asked to complete the Living with Pulmonary Fibrosis questionnaire to evaluate their IPF symptoms. Participants will also undergo a specialized lung scan (HRCT) at Baseline and at the End of Treatment to measure changes in lung fibrosis. Interventions: LTI-03 and placebo are provided in powder-filled capsules that participants will self- administer using an inhaler. Placebo capsules look like LTI-03 capsules but have no active ingredients. Approximately 120 participants will be randomly assigned in a blinded manner to one of study drug treatment groups.
