There are about 2656 clinical studies being (or have been) conducted in Puerto Rico. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
This clinical trial keeps track of and collects follow-up information from patients who are currently enrolled on or have participated in a Children's Oncology Group study. Developing a way to keep track of patients who have participated in Children's Oncology Group studies may allow doctors learn more about the long-term effects of cancer treatment and help them reduce problems related to treatment and improve patient quality of life.
This study will determine the effectiveness of adding a parent-involved intervention to cognitive behavior therapy in reducing depressive symptoms among Latino adolescents with depression.
This clinical trial studies cancer survivors to identify those who are at increased risk of developing late-occurring complications after undergoing treatment for childhood cancer. A patient's genes may affect the risk of developing complications, such as congestive heart failure, avascular necrosis, stroke, and second cancer, years after undergoing cancer treatment. Genetic studies may help doctors identify survivors of childhood cancer who are more likely to develop late complications.
This study collects specimens from volunteers for use in studies by NIAID's Vaccine Research Center. A number of different types of specimens or samples can be collected, including blood, urine, body fluids or secretions, skin swabs, or skin biopsies. The samples are used for medical research, including the study of HIV, hepatitis, and other diseases; immune system responses, such as responses to vaccinations or infections; and for research on vaccine development. Blood samples may be collected either by ordinary blood drawing (phlebotomy) or by apheresis, a procedure for collecting a larger quantity of blood cells or plasma than would be possible through simple blood drawing. For this procedure, the subject lies on a recliner or couch. Blood is removed through a needle in the vein of one arm and spun in a machine that separates out the desired component (plasma or white blood cells). The remainder of the blood is returned either through the same needle or through a needle in the other arm. The procedure takes about 1 to 3 hours. Volunteers who are 18 years of age and older, including participants in other NIH research protocols, may be eligible. Individuals who have a condition that the research staff considers a reason not to make a sample donation will be excluded from the study. Participants may have only one sample collected or may be asked to undergo repetitive sample collection procedures, depending upon the requirements of the particular research project for which the samples are being collected. Each individual's enrollment is for a 1-year period, which can be extended.
The purpose of this study is to obtain informed consent to use stored human biological materials (HBM) (e.g., blood and other tissues) for future studies that may include genetic testing.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy and kill more tumor cells. It is not yet known if combination chemotherapy is more effective with or without radiation therapy and/or surgery in treating Ewing's sarcoma. PURPOSE: This randomized phase III trial is studying different combination chemotherapy regimens to see how well they work when given with or without peripheral stem cell transplantation, radiation therapy, and/or surgery in treating patients with Ewing's sarcoma.
The purpose of this study is to see if emtricitabine is safe in children infected with HIV and to determine the best dose.
