Filter by:Iron deficiency is common in cardiorespiratory diseases and appears to contribute to a worse outcome. This human physiology study will examine the extent to which human skeletal muscle metabolism and exercise physiology are impaired by iron deficiency.
The study is designed to assess the bioavailability of iron from 4 different iron fortified savoury food products
Multicentre randomized controlled trial to evaluate the optimal treatment for patients who developed an iron deficiency after Roux-en-Y Gastric bypass.
Investigation of Iron Bioavailability from extruded rice grains fortified with Ferric Pyrophosphate alone or in combination with different Zinc Compounds; Ferrous Sulfate serves as a Reference.
The prevalence of iron deficiency in blood donors has been demonstrated to be a direct consequence of repeat blood donations. Given the adverse effects of iron deficiency, it is priority to implement programs to remediate iron deficiency issues associated with blood donations. To explore this issue, the study's aims to: 1. Determine whether regular blood donors provided with accurate information about their iron status and written recommended courses of action will take steps to prevent/mitigate iron deficiency on their own without being given iron supplements by the blood center; and 2. Determine if two different amounts of iron provided by the blood center will prevent/mitigate iron deficiency in regular blood donors. To conduct this randomized, placebo controlled study, participant donors will be assigned to one of two arms and followed for a 24 month period. Each subject will provide additional blood samples of 7 ml and 4.5 ml at each study visit for the purpose of tracking hemoglobin (Hgb), ferritin, soluble transferrin receptor (sTfR), and hematology laboratory results. Under the two study arms, subjects are to be randomized into one of the following five blinded categories: - Receive a thank you letter after each blood donation. - Receive a letter informing them of their ferritin result at each visit, along with recommendations for blood donation. - Receive pills to take daily that contain no iron (a placebo or inert pill). - Receive pills to take daily that contain 19 mg of iron (the typical amount in a multivitamin with iron). - Receive pills to take daily that contain 38 mg iron (the typical amount in an over-the-counter iron supplement).
In this study, iron- and zinc-biofortified pearl millet will be fed to young children in Mumbai, Maharashtra, India over a period of nine months to measure growth and immune function in comparison to children receiving non-biofortified pearl millet.
Investigation whether a switch from oral iron to intravenous ferric carboxymaltose can reduce dose requirements of erythropoiesis-stimulating agents (ESA) and improve Hb levels and iron status in adult patients with non-dialysis-dependent CKD who were on a stable ESA/oral iron schedule for 6 months prior to enrolment.
The investigators plan a study to randomize 540 children in Nepal to early (≤30 seconds) or late (≥180 seconds) clamping of the umbilical cord at birth. The children will be followed with blood tests (hemoglobin and ferritin) at 8 and 12 months of age, and their development is evaluated by questionnaire (Ages & Stages Questionnaire ) at 12 months of age, and by testing (Bayley -III) at 18-24 months of age. By implementing the project in a country with a high proportion of anemia at one year of age (about 75%), we can reduce the number of children in the study and still achieve significant results. Iron deficiency is a global health problem and causes anemia and impaired neurodevelopment in children. Anemia is estimated by WHO to occur among 25% of all children before school age, and the corresponding figure in Europe is 3-9 %. By waiting 3 minutes to clamp the cord after birth, a large part of the child's blood volume remaining in the placenta is transfused over to the child's body. Research shows that the neonate's blood volume can increase by about 40% and this blood contains 3 to 4 months' supply of iron. In Sweden, we have shown that late clamping of the umbilical cord could reduce iron deficiency in children at four months of age by 90%. Globally, most countries practice early cord clamping and the child is deprived of the placental blood transfusion. The hypothesis of the study is that by delaying the clamping of the umbilical cord, anemia at 8 and 12 months will be reduced an this in turn will be beneficial for the childrens development. The project will be implemented at Paropakar Maternity and Women 's Hospital, Kathmandu. It hosts approximately 23,000 births annually.
According to a national study in 2002, the prevalence of ID, IDA, and ID+IDA among pregnant women in China was 42.6%, 9.1%, and 61.7% respectively. A similar study in Hebei province at the same time showed that the prevalence of IDA among pregnant and lactating mothers was 46.39% and 47.21% respectively. There was a significant difference between urban and rural areas. Women living in rural areas had higher chances of having IDA (p<0.01). WHO and UNICEF recommend taking iron, folic acid and multiple micronutrients during pregnancy. However, we don't know much about their influence on maternal and infant health and their clinical effectiveness. Health Department of China recommends taking 400ug folic acid before pregnancy and during early pregnancy. But for various reasons, not all expecting mothers take this advice. Besides, we don't have a national level technical standard of how to take nutrition supplements during pregnancy. Therefore, it's crucial for us to study if iron/folic acid or folic acid only can prevent perinatal complications, as well as their influences on infant and toddler health. The purpose of this study is to test whether taking iron/folic acid and folic acid only from early pregnancy until delivery will lower the chances of pregnancy complications, and to see how supplements affect gestation results. As well, it will evaluate a) whether taking iron supplement during pregnancy can prevent IDA during pregnancy; b) whether taking iron supplement can increase mother and fetus iron storage; and c) how mother's iron level affects newborn's iron level. We hope to understand nutrition conditions during pregnancy and investigate the relations between pregnancy diet and complications during pregnancy, weight gain during pregnancy, and newborn birth weight. We will evaluate the influence of taking iron and folic acid during pregnancy on the health of infants and toddlers.
Iron deficiency (ID) with or without anaemia (IDA) is a major public health problem worldwide, especially in women of reproductive age and young children. Iron supplementation is an effective strategy to prevent and treat ID and IDA. There is a lack of data on iron bioavailability from different supplementation regimens and how to optimize bioavailability in a cost-effective and patient-friendly way. The daily supplementation with 1-4 mg Fe/kg body weight for 3 months is reported to be the most effective method to rapidly increase iron stores in subjects with ID and IDA. In IDA patients, medical practitioners often prescribe supplementation regimens with 120 mg iron per day split into 2 doses with 60 mg iron, arguing that the splitting would increase iron bioavailability compared with one single high dose. However, there is no scientific evidence for this assumption; to the contrary, results from a recent study suggest that iron bioavailability from a second supplementation dose of iron after a first supplementation dose of iron is impaired due to increased hepcidin levels. To address this bioavailability issue, the present study will determine iron absorption from 120 mg iron administered for 3 consecutive days and compare it with that from 2 doses of 60 mg iron per day administered for 3 consecutive days. The investigators hypothesize that the iron bioavailability from the single daily dose will be lower than that from the 2 doses. By measuring also hepcidin, this study will provide important insights on the iron bioavailability from a single dose of iron and on the same amount iron split into two doses (b.i.d. administration).
