The goal of this study is to This research team is conducting this study to develop methods to measure the biological impact of exposure to the chemicals released following the February 3, 2023 train derailment on residents of East Palestine, Ohio, and surrounding communities. The main question it aims to answer is: * What biological impact will be measured based on DNA damage? * In participants who provide a biospecimen, how are biomarker changes related to proximity to the derailment and variations in residents' health histories and behaviors? Participants will: * Complete a brief survey asking about experiences related to the February 3, 2023 train derailment, health experiences, and concerns following the derailment, and background information regarding health history. * Possibly contribute biospecimens such as blood, spit, hair, and/or toenail clippings. * Receive communication about study updates and future research opportunities. * A total of 40 study participants will be recruited to participate in a 90-minute interview. The interviews will be video and audio recorded.
A comprehensive mechanistic and epidemiological study to obtain banked cord blood samples from consecutive childhood leukemia patients enrolled in the COG Project:EveryChild (APEC14B1) study. Will attempt to backtrack the initiating genomic alteration identified in the matched diagnostic leukemia sample and molecularly characterize pre-leukemic cells. The ultimate goal of this research is to pinpoint the cell of origin of leukemogenic alterations formed in utero, elucidating the etiology of these initiating mutations (as opposed to frank leukemia), and devising a test for circulating pre-leukemia that can be applied on a population-wide basis.
Somatic mosaicism in cancer associated genes is one potential explanation for discordance in childhood cancer that has not been fully explored to date. This pilot study will focus on twins with central nervous system (CNS) tumors who are identified through the Children's Oncology Group's Project: EveryChild (PEC) registry or volunteer.
This is a phase II, open-label, prospective study of T cell receptor alpha/beta depletion (TCR α/β TCD) peripheral blood stem cell (PBSC) transplantation for children and adults with hematological malignancies. This is a safety/feasibility study of the investigational procedure/product.
Background: Clonal Hematopoiesis of Indeterminate Potential (CHIP) is a change in a person s DNA that can increase a person s risk of developing blood cancers or cardiovascular disease. CHIP occurs mostly occurs in older people. Clonal cytopenia of undetermined significance (CCUS) occurs when one or more blood cell types is lower than it should be and is associated with a change in their DNA. Researchers want to learn more about how CHIP and CCUS progress. Objective: To examine the natural history of people in a study of CHIP and CCUS to (1) verify the association of myeloid somatic mutations with atherosclerosis and blood cancers, and (2) find new potential clinical associations. Eligibility: Adults 18 and older with CHIP with a somatic pathogenic variant associated with blood cancers. Adults with CCUS are also needed. Design: Potential participants will be screened with gene testing. For this, they will give a blood sample. They will also be enrolled in NHLBI screening protocol #97-H-0041. Those who pass this screening will visit the NIH Clinical Center for more screening tests. For this, they will give a blood sample. They will have a physical exam. They will give their medical history. They may give a urine sample. Those with CCUS will have bone marrow taken. Eligible participants will give blood and urine samples. Their heart activity will be monitored and tested. The arteries in their neck will be assessed using ultrasound. They will have liver and heart scans. They will have a bone mineral density scan. They will have lung function tests. They will have the inside of their cheek swabbed or have a skin punch biopsy. They will have the option to have advanced scans done of their heart and full body but this is not required. Participants will have yearly follow-up visits for 10 years. They will repeat the above procedures every 1-3 years depending on the procedure.
BACKGROUND: Endometrial cancer is a common and deadly cancer for women. It is getting more common and deadly because risk factors like age and obesity are increasing. Also, this cancer is becoming more common and deadly for black women than white women. Researchers want to find better ways to take samples and test them for this cancer. They want to study this for a racially diverse population. One way to take samples might be from a tampon. If identified early, endometrial cancer can be highly curable; however, the earliest stages may be asymptomatic, and clinical symptoms are often missed. Combining sensitive molecular testing approaches with non-invasive sampling techniques may to lead to the development of novel endometrial cancer early detection approaches with the potential to overcome disparities in access to care and time to diagnosis and treatment. In contrast to endometrial cancer, ovarian cancer is typically detected at advanced stages with poor survival since symptoms manifest only late in the disease process and are very unspecific. Racial disparities in ovarian cancer incidence and mortality are also much less pronounced. Racial disparities can manifest particularly when screening, symptom appraisal and early detection, and effective treatment interventions have important roles in determining outcomes of cancers. OBJECTIVES: The purpose of this study is to see if it is possible and acceptable for individuals to have an endometrial or ovarian sample collected by using a tampon placed in the vagina. The investigators will look at DNA in these samples. DNA is the genetic information participants inherited from their parents. The investigators want to see whether the investigators can find changes in DNA and proteins related to endometrial or ovarian cancer from tampon samples. Tests on the samples from tampons will help to understand endometrial and ovarian cancer. The samples collected during this study will be used for research related to both endometrial and ovarian cancer and non-cancer conditions. ELIGIBILITY: Women at least ≥18 years undergoing clinically-indicated hysterectomy and/or bilateral salpingo-oophorectomy for endometrial or ovarian cancer, cancer precursors, or benign conditions. DESIGN: 1. Participants will put a tampon in their vagina at least 30 minutes before their surgery. 2. Participants will take a short survey. 3. The tampon will be collected during the surgery. 4. A small piece of tissue will be collected from the uterus +/- ovary that is removed in surgery. 5. Participants will give a blood sample. 6. Before or after surgery, participants will answer questions. These will be about their medical history and basic data such as age and race. 7. Researchers will follow participants medical records for up to 5 years after the study. Additional blood may be taken from patient if patient agrees. 8. Researchers will study the samples and tampons. They will compare how well cancer and other markers are detected between the samples.
