Filter by:This study involved human volunteers undertaking a high-altitude expedition. It assessed changes in physiological parameters of relevance to high-altitude cardiopulmonary physiology. Participants included a subgroup of those taking part in an existing adventurous training expedition and were randomised in a 1:1 fashion to receive either intravenous iron or normal saline several weeks prior to departure. During the expedition, participants were investigated by means of transthoracic echocardiography, peripheral oxygen saturation measurement and heart rate monitoring and through the drawing of venous blood samples. Bloods were later analysed for markers of iron status.
This is a randomized non inferiority trial to evaluate the response to iron therapy in the standard daily vs. intermittent (three-four times a week on nonconsecutive days) groups by using hematological markers (hemoglobin, hematocrit, transferrin, hepcidin, ferritin, human soluble transferrin receptor). The secondary outcome is to evaluate gastrointestinal discomfort and adherence to therapy between two treatment groups.
Food fortification is regarded as a safe and cost-effective approach to counteract and prevent iron deficiency. Rice is a staple food for millions of people living in regions where iron-deficiency anaemia is a significant public health problem. Therefore, rice may be a promising fortification vehicle. Ferric pyrophosphate (FePP) is an acceptable iron compound for rice fortification, due to its white colour and low reactivity with the rice matrix. However, iron from FePP generally has a low bioavailability. To increase the low iron bioavailability of FePP in fortified rice, ligands acting as solubilizing agents have been suggested, such as citric acid/trisodium citrate (CA/TSC), ethylenediaminetetraacetic acid (EDTA) and sodium pyrophosphate (NaPP). It is however unclear to which extent CA/TSC would enhance iron bioavailability in presence of phytic acid, a common inhibitor of iron absorption found in whole grains and legumes. Zinc oxide reduces iron bioavailability from FePP with and without CA/TSC, in contrast to Zinc sulphate. It is however unclear if this decrease would be also expected in presence of EDTA as solubilizing agent. Further, NaPP has been suggested as a solubilizing agent, enhancing the bioavailability from FePP in bouillon cubes. This study aim to test its effect in rice. Meals containing a high (bean sauce) and low (mixed vegetable) phytic acid level sauce will be used to simulated varying dietary backgrounds, allowing to answer the question which solubilizing agent is viable in enhancing iron bioavailability.
Food fortification is regarded as a safe and cost-effective approach to counteract and prevent iron deficiency. Rice is a staple food for millions of people living in regions where iron-deficiency anaemia is a significant public health problem. Therefore, rice may be a promising fortification vehicle. Hot and cold extrusion, have been identified as the major methods for rice fortification. Extruded rice has the advantage of incorporating vitamins and minerals into the food matrix. Cold, warm and hot extrusion differ in the processing temperature and the physical structure of fortified rice kernel matrix. A recent human study in young women showed fractional iron absorption was higher in cold extruded rice compared to hot extruded Rice and this was associated with changes in the starch microstructure. These changes cannot be detected in warm extruded rice, thus, our aim is to test the iron bioavailability in difference extrusion methods; hot and warm and cold with and without the solubilizing agent CA/TSC. This will provide information on optimized rice formulations for optimal iron delivery.
The purpose of the study is to see the percentage of non-anemic, first trimester gravidas presenting to their obstetricians, who are iron deficient.
Iron deficiency is prevalent in heart transplant recipients, and may be associated with reduced functional capacity. The IronIC trial is designed to assess the effect of intravenous iron isomaltoside on exercise capacity, muscle strength, cognition and quality of life in iron-deficient heart transplant recipients
The primary objective of this study is to compare iron absorption of high surface area ferric phosphate with that of ferrous sulfate and bulk ferric phosphate in a rice-based meal in non-pregnant women.
This randomized controlled trial includes pregnant women with anemia. They are randomized to IV iron infusions or to oral iron supplementation. Pregnancy outcomes are assessed.
Adiposity is a state of sub-clinical inflammation, thus hepcidin is increased in adiposity, often leading to iron deficiency in this population group. Central adiposity is generally considered having a greater negative effect on health compared to peripheral adiposity. Whether this can be also seen in hepcidin and thereby in iron absorption is uncertain.
This is a pilot study to test the utility of an integrated approach in the management of the anemia of chronic kidney disease through the administration of both an erythropoietic stimulating agent and iron. Subjects will be studied for 6 months during which all iron dosing will be recommended using a computer based tool using model predictive control. Comparisons will be made to the 6 months prior to enrollment in to the study.
