Filter by:Mothers and young children in rural Ethiopia lack sufficient nutrition, and a compounding factor is presence of high levels of fluoride (> 5-10 mg/day) affecting body functions. Interventions involving chickens to provide eggs and eggshell (a source of calcium) are one solution. The overall purpose is to examine how increasing dietary calcium by using eggshell powder (ESP) reduces fluoride (F) absorption in women. It is known calcium binds F to prevent its absorption but application of this to a community based study has not been tested. The aim is to provide chickens to produce eggs for young children and to provide ESP to women (mothers). For children, an egg a day should improve growth and nutritional status. For women, the ESP provides calcium to reduce fluorosis and therefore improve function without affecting iron and zinc status. For the women, blood samples will be tested in a subsample for F, calcium, zinc and iron; urine samples will be measured for F, calcium and creatinine (to correct spot urine). Hemoglobin will be measured as an indicator of overall nutritional status in women and children. Nutritional status of young children (6-18 mo) and of their mothers prior and after the intervention (by 6 months) will be assessed. between 6 and 12 month there will be monitoring for sustainability of chilckens in the community; for continued use of egg (in children) and ESP (in women); during this time the control group will receive chickens and also undergo monitoring. The study will take place in the Rift valley of Southern Ethiopia. Identification of the knowledge, attitude and practices (KAP) of mothers on egg consumption will be done at baseline and at the end ("endline"). Caregivers will be instructed to give each child 1 egg (cooked) per day in the intervention, and one "bottle cap" of eggshell powder (1000 mg calcium) per day for themselves. Families receiving chickens will be instructed on cage construction. Throughout the study, any problems arising in keeping chickens will be recorded in order to assess the feasibility and practicality of raising chickens as way to mitigate fluorosis and improve nutritional status.
The effectiveness of micronutrient powders or MNP as a strategy for the prevention of micronutrient deficiencies has been described in the literature. However, few studies have shown the impact of the inclusion of other simultaneous actions on the different dimensions of food and nutritional security (as in the case of the project "Papas más nutritivas") that will contribute to the improvement of nutritional status, obtaining potentially greater benefits. The objective is to establish the existence of difference in hemoglobin values (and other biochemical parameters as secondary outcomes) among children aged 6 months to 5 years who receive home fortification with micronutrient powders (MNP) belonging to the project "Papas más nutritivas", and children with home fortification with MNP but not belonging to the project.
Background: - Some treatments for cancer or other diseases can lead to infertility in women. These treatments include chemotherapy, some stem cell transplants, and pelvic radiotherapy. They are called gonadotoxic therapies. Women can now have their eggs frozen before they have these treatments. This may allow them to get pregnant later. Researchers want to learn more about this technology and processes. Objectives: - To provide egg freezing for women having gonadotoxic therapies at NIH. To learn more about the effects of these therapies. Eligibility: - Women at least 18 years old who are past puberty and before menopause. They must be scheduled to have gonadotoxic therapies. Design: - Participants will be screened with medical history and blood and hormone tests. They will also have a physical exam and transvaginal ultrasound. - Ovary stimulation: participants will have medications injected under the skin. These increase the chance of fertility. This phase will take about 8 20 days. Participants will have blood drawn and transvaginal ultrasound daily or every other day. Some participants will also have blood thinner injected daily. - Egg retrieval: participants will check in to the hospital. Eggs will be removed with a needle during a short surgery. Participants will be awake but sedated. - Participants may stay overnight in the hospital. - They will return every 1 3 days for 1 3 weeks for blood tests. - Mature eggs will be frozen after egg retrieval and immature eggs (which cannot be fertilized for clinical use) will be used for research. Participants can use their eggs in the future at outside, private fertility clinics to try to become pregnant. If the eggs are stored for more than 5 years, participants must pay for storage.
