This study evaluates the change of quality of life, treatment decision and utilization of health care depending on the use of palliative care in advanced cancer patients by a prospective cohort study. Participants will be separated into different groups by their intentions for using palliative care. Every participant will carry out the questionnaire per 3 months. This cohort study will be ended a year after each participant enrolls. However, if the participant didn't survive during this study, the caregivers will be asked to fill out additional questionnaire after 3 months of the death.
Background: - Pregnant women are encouraged to take the vitamin folate. It helps prevent some birth defects. Children of mothers who take it also have less risk of some cancers. Between 1993 and 1995, some women in China took the vitamin daily before and during early pregnancy. Another group did not. This study will follow up on children born to both sets of women. (The children were born between 1994 and 1996.) Researchers will use these data to study the link between folate and cancer in infants and children. Objective: - To see if folate may reduce childhood cancer if women take it every day before and during early pregnancy. Eligibility: - Mothers who took part in a Chinese folic acid study between 1993 and 1995 and their offspring. Design: - Mothers of children in the study will sign a consent form. The form lets the researchers review the child s medical history. They may also review data about their cancer diagnosis. The children will also sign a form.
Periconceptional folic acid supplements of 400 (Micro) daily prevent neural tube defects (NTD) in offspring. Some data suggest that periconceptional folic acid supplements, folate levels during pregnancy, and/or certain variants in the gene that encodes methylenetetrahydrofolate reductase (MTHFR), a key enzyme that catalyzes synthesis of 5-methyltetrahydrofolate [the primary methyl donor in most metabolic pathways involving methylation including DNA methylation] from 5,10 methylenetetrahydrofolate may be associated with reduced risks of certain adverse events during the prenatal period, birth weight and certain serious diseases in offspring, while other studies have raised concerns about increased risks of specific serious disorders. Only one study has examined late health effects in mothers that might be associated with use of periconceptional folic acid supplements. We propose to study potential health benefits and adverse effects of periconceptional folic acid supplements in a 15-year follow-up of offspring and mothers. In the offspring, we will evaluate whether periconceptional folic acid supplements reduced risk of external congenital birth defects and childhood acute lymphoblastic leukemia, and whether risks are reduced or increased for other pediatric disorders linked with periconceptional folic acid supplements including asthma, pervasive developmental disorders and autism, diabetes, obesity and blood pressure. In the mothers, we will assess cardiovascular diseases and associated risk factors, breast and colorectal cancers and precursor conditions, and other cancers. We will also conduct exploratory assessment of other serious diseases in mothers. To increase the limited data on the morbidity and survival of children born with a major birth defect, particularly in low- or middle-income countries, we plan to assess morbidity and mortality outcomes in children identified with neural tube defects as part of our follow-up. The women and children who participated in the joint China-U.S. Community Intervention Program (CIP) trial (N=243,779 women treated or not treated with folic acid in the periconceptional period and their offspring) represent unique cohorts whose periconceptional exposure to folic acid is well documented. We propose to follow a sample of 22,000 CIP mothers and their offspring (currently 14 to 17 years of age), to ascertain vital status, medical history, and lifestyle habits. The study will clarify whether there are differences with respect to growth, physical development during the puberty period, selected serious morbidity and mortality in offspring and risks of serious health outcomes and mortality in mothers associated with periconceptional folic acid supplements. Data from this study will inform us about cohort participation rate, cost, and effective approaches for future follow-up of the full cohort. The current protocol focuses on a pilot study (Pilot Study # 1) in which we will carry out two specific aims in 500 families. We will test and evaluate the most effective approaches to trace the mothers who enrolled in the CIP in 1993-1995 in CIP counties, fathers, and children. If the child is not living with the biological mother, we will trace the caretaker or next of kin with whom the child is living. We will also conduct in-person interviews, obtain anthropometric and blood pressure measurements and determine cohort participation rate in a sample of 500 CIP families from two of the 21 CIP project counties to obtain health information, medical history, and vital status. We will attempt to enroll in the pilot study 500 mothers/caretakers and 500 offspring, and 500 fathers (Total N=1500). Excluded from the Pilot Study #1 at this time are the families in which the mother or the child is deceased. We will seek permission from the IRB to enroll these families at a later date.
