NCT02635009
This randomized phase II/III trial studies how well whole-brain radiation therapy works and compares it with or without hippocampal avoidance in treating patients with small cell lung cancer that is found in one lung, the tissues between the lungs, and nearby lymph nodes only (limited stage) or has spread outside of the lung in which it began or to other parts of the body (extensive stage). Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. The hippocampus is part of the brain that is important for memory. Avoiding the hippocampus during whole-brain radiation could decrease the chance of side effects on memory and thinking. It is not yet known whether giving whole-brain radiation therapy is more effective with or without hippocampal avoidance in treating patients with small cell lung cancer.

NCT00076830
This study offers evaluation and treatment of patients with a suspected connective tissue disorder. The protocol is not designed to test new treatments; rather, patients receive standard care. The study is designed to: 1) allow NICHD's staff to learn more about connective tissue disorders, 2) train physicians in the evaluation and treatment of these disorders; and 3) establish a pool of patients who may be eligible for other NICHD protocols for connective tissue disorders. (Participants in this protocol will not be required to join another study; the decision will be voluntary.) Patients of all ages with a suspected connective tissue disorder and their unaffected family members may be eligible for this study. Participants undergo diagnostic procedures that may include a medical history, physical examination, X-ray studies, eye examinations, and blood drawing, as well as other specialized tests, when needed. Additional tests may include: * Blood test for DNA genetic analysis * Skin biopsy: Removal of a small piece of tissue for microscopic examination. The area of skin selected for the biopsy is numbed and a small circle of skin, usually from the upper arm, is removed with a surgical cookie cutter-like instrument. * Magnetic resonance imaging (MRI): This test uses a strong magnetic field and radio waves to show structural and chemical changes in tissues. The patient lies on a table that slides into a narrow cylinder containing a magnetic field. Ear plugs are worn to muffle loud knocking and thumping sounds that occur with electrical switching of the magnetic fields. * Computed tomography (CT) scans: This test allows the doctor to view the organs inside the body in small sections. The patient lies in a doughnut-like machine. Scanning can be done from different angles, allowing a three dimensional picture of the part of the body being studied. It may be done with or without injection of a contrast material. * Referral to appropriate sub-specialists when potential complications are found.

NCT02520609
Background: Metabolism refers to the many chemical pathways by which various compounds, including food, are processed and used in the body. People with non-alcoholic fatty liver disease (NAFLD) have too much fat in their liver cells, but what causes it is unclear. One explanation is that people with NAFLD process food and metabolize it differently than people without NAFLD. Researchers want to compare how food is metabolized in people with and without NAFLD. Objective: To better understand how food intake influences the development and progression of NAFLD. Eligibility: People ages 18 and older with NAFLD or with a non-NAFLD metabolic syndrome Healthy volunteers ages 18 and older Design: Participants will be screened with medical history, surveys, physical exam, and blood tests. This will have ultrasound of the abdomen. This uses sound waves to image internal organs. Participants will stay at the Clinical Center for 2 nights. They will fast he first night. On the second day they will: Have their metabolism monitored in a metabolism research room for 24 hours Have a catheter inserted into an arm vein for several blood tests Drink an Ensure Plus for breakfast Have solid meals for lunch and dinner Have several urine tests. The final morning, they will: Have more blood tests. Have a DXA test to measure the fat in the body. They will lie on their backs for 15-25 minutes while an x-ray machine is positioned over areas of the body.
NCT02531880
Background: \- The blood-brain barrier separates the brain from the rest of the body. Epilepsy is a neurological disease that causes seizures. It can affect this barrier. Researchers think a contrast agent called mangafodipir might be better able to show areas of the brain that epilepsy affects. Objective: \- To see if mangafodipir is well tolerated and safe. To see if it can show, on an MRI, areas of the brain that epilepsy affects. Eligibility: * People ages 18-60 who: * Have epilepsy not controlled by drugs * Prior or concurrent enrollment in 18-N-0066 is required Design: * Participants will be screened with: * Medical history * Physical exam * Blood and urine tests * Participants will have up to 6 visits in 1-3 months. Those with epilepsy will have an inpatient stay lasting 2-10 days. Visits may include: * Video-EEG monitoring for participants with epilepsy * An IV catheter put in place: a needle guides a thin plastic tube into an arm vein. * Getting mangafodipir through the IV. * 5 MRI scans over a 10-day period: a magnetic field and radio waves take pictures of the brain. Participants lie on a table that slides into a metal cylinder. They are in the cylinder for 45-90 minutes, lying still for up to 10 minutes at a time. The scanner makes loud knocking sounds. Participants will get earplugs. * A final MRI at least 2 weeks after receiving mangafodipir. Gadolinium is given through an IV catheter....
NCT00007150
This study will evaluate the effectiveness of a test called MCV in guiding phlebotomy (blood drawing) therapy in patients with hemochromatosis an inherited disorder that causes too much iron to be absorbed by the intestine. The excess damages body tissues, most severely in the liver, heart, pancreas and joints. Because iron is carried in the hemoglobin of red blood cells, removing blood can effectively lower the body s iron stores. Patients with hemochromatosis undergo weekly phlebotomy treatments (1 pint per session) to deplete iron stores. This usually requires 10 to 50 treatments, after which blood is drawn every 8 to 12 weeks to prevent a re-build up of iron. A test that measures ferritin a protein involved in storing iron is commonly used to guide phlebotomy therapy in hemochromatosis patients. This study will compare the usefulness of the ferritin test with that of MCV, which measures red blood cell size, in guiding phlebotomy therapy. In addition, the study will 1) examine whether keeping iron levels low during maintenance therapy can help heal severe liver disease and improve arthritis in affected patients, and 2) design a system for making blood collected from hemochromatosis donors available for transfusion into other patients. Patients 15 years and older with diagnosed hemochromatosis or very high iron levels suggesting possible hemochromatosis may be eligible for this study. Candidates will have a history, physical evaluation, review of medical records and blood tests, and complete a symptoms questionnaire. Participants will have the following procedures: * Phlebotomy therapy every 1 to 2 weeks, depending on iron levels * Blood sample collection for blood cell counts and iron studies at every phlebotomy session * Blood sample collection (about 2 tablespoons) every 1 to 2 weeks after iron stores have been depleted * Phlebotomy every 8 to 12 weeks after iron stores are used up to prevent re-build up of excess iron With each blood donation that will be made available for transfusion to other patients, participants will answer the same health history screening questions and undergo the same blood tests given to all regular volunteer blood donors. These include screening for the HIV and hepatitis viruses and for syphilis. Patients who meet height and weight requirements may be asked to consider "double red cell" donations using apheresis. In this procedure, whole blood is collected through a needle placed in an arm vein, similar to routine phlebotomy. The blood then circulates through a machine that separates it into its components. The red cells are removed and the rest of the blood is returned to the body, either through the same needle or through a second needle in the other arm. Patients who have very high iron levels or an enlarged liver will be offered evaluation by the NIH Liver Service. Those judged to be at increased risk for cirrhosis may be advised to undergo a liver biopsy. If cirrhosis is found, the patient will be asked to consider a repeat biopsy after 3 to 5 years of continuous iron depletion to see if scarring has improved. Patients with arthritis will be offered evaluation by the NIH Arthritis Service and, depending on symptoms, may be advised to have X-ray studies or a joint biopsy.
NCT03581318
Background: Magnetic resonance imaging (MRI) is an important non-invasive tool to study and diagnose cardiovascular disease. MRI scanners use strong magnetic fields and radio waves to create pictures of body organs. Researchers want to find better MRI methods and new ways of imaging cardiovascular disease and better understand normal and abnormal cardiovascular and brain function. Researchers are also interested in seeing if gadolinium, the commonly used MRI contrast agent, stays in the body long after the MRI was performed. Objectives: To develop new methods for imaging the heart and other organs of the body. To describe cardiovascular diseases using newer MRI methods To look at the relationship between cardiovascular disease and cardiovascular risk factors and other organ systems To look for gadolinium deposits in the brain from prior exams. Eligibility: Healthy people and people with known or suspected cardiovascular disease ages 7 and older may be eligible for this study. Researchers may be particularly interested in those who: * Have suspected or known cardiovascular disease * Were previously exposed to a gadolinium-based contrast agent, * Need to have a heart MRI scheduled * Need a test of the heart or other body part or will be undergoing a future cardiac catheterization Design: There are multiple arms to the study with optional components; therefore, there are multiple variations as to what an individual participant s experience may involve. Participants will have an MRI scan lasting up to 2 hours. The scanner is a large hollow tube. During the scan, there may be loud knocking and buzzing sounds caused by the scanner. Participants will lie on a table that slides in and out of the tube. Their vital signs may be monitored. Participants may have a test of heart electrical activity using wires connected to pads on the skin. Participants may have blood drawn. Participants may be injected with an MRI contrast agent through a plastic tube inserted in the arm. ...
NCT00713492
This study will test the reliability of a procedure for self-administering ethanol (alcohol) intravenously (through a vein), using a computer-assisted method. People ordinarily self-administer alcohol through drinking alcoholic beverages, but blood alcohol levels resulting from drinking vary greatly among individuals. For research on alcohol dependence and treatment, a tool for achieving precise blood levels is needed. In addition to testing this method of alcohol administration, the study will examine self-administration behavior and resulting breath alcohol concentration, the effects of alcohol on the participants, and differences between men and women in alcohol self-administration. Healthy normal volunteers between 21 and 45 years of age may be eligible for this study. Participants are assigned to one of two study groups. Group 1 undergoes three 7-hour study sessions and group 2 participates in two sessions, each of which includes the following procedures: * Breathalyzer and urine tests for alcohol and illicit drug use. * Urine pregnancy test for women. * Light lunch. * Questionnaire about health and recent drinking. Alcohol infusion: Subjects are seated in a comfortable chair and instructed on how to use a computer to give themselves a short infusion of alcohol through a catheter (plastic tube) that has been inserted into a vein in their the arm. Sensors are placed on their chest to monitor heart beat and their neck to record skin blood flow. At the start of the session, subjects complete questionnaires about any drug effects and urges to drink they may be feeling. They are trained on how to use the computer to administer alcohol and are then allowed to self-administer alcohol through the catheter any time they like, as long as their peak breath alcohol level does not exceed 0.1 g% (a level that would result from ingestion of 4 to 6 drinks in most people). If that point is reached, the computer automatically inactivates self-administration until the level is lowered again. Breathalyzer readings are taken every 15 to 30 minutes. Subjects may read, watch television or videos or listen to music during the sessions. Recovery: At the end of the 2.5 hours of self-administration, the catheter is removed and subjects can eat, read, watch television and relax in the clinic until their breath alcohol level falls below 0.02 g%, usually after 2.5 to 3 hours, when they can go home by taxi or with a pre-arranged designated driver. ...
NCT01109420
Background: \- Researchers are studying types of thyroid cancer that seem to cluster in families. Non-medullary thyroid cancer accounts for the vast majority of all types of thyroid cancer, but little is known about possible genes that may cause the cancer. More research is needed to develop the best ways to screen for familial non-medullary thyroid cancer (FNMTC) so that it can be diagnosed and treated at an early stage. Objectives: * To evaluate the natural history of FNMTC. * To determine the best screening strategy for FNMTC. * To identify genes that may indicate susceptibility to FNMTC. Eligibility: \- Individuals at least 7 years of age who have two first-degree relatives (e.g., parents, children, siblings) who have or have had non-medullary thyroid cancer or a documented diagnosis of non-medullary thyroid cancer and one living relative with documented non-medullary thyroid cancer. Design: * Participants will be evaluated by family history pedigree, physical examination, imaging (including possible neck ultrasound and radioactive iodine scans), and laboratory testing. * Participants who agree to have blood or other biological samples collected will be asked to enroll in an additional study to provide the appropriate samples and tissues. * After the initial study evaluation, participants who are not found to have a malignant thyroid tumor will be re-screened every year with non-invasive imaging studies. Participants who are found to have a malignant thyroid tumor will be informed of possible treatment options....

NCT07230834
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)
