Filter by:As a follow-up to the RAPIDIRON Trial (NCT05358509), and in combination with the RAPIDIRON-KIDS Study (NCT05504863), this study will involve infants of RAPIDIRON Trial participants recruited at one site in Karnataka and is designed to implement a magnetic resonance imaging (MRI) protocol and incorporate neuroimaging measures. Implementation of this study will promote an understanding of the effects on fetal and neonatal brain development, including iron deposition in brain tissues, when a woman is treated for iron deficiency anemia (IDA) by either (a) providing her oral iron tablets and instructions for use; or (b) administering a single-dose IV iron infusion for the treatment of IDA during pregnancy.
The hypothesis of this research is that oral iron prescribed in a single dose in alternate day could mitigate the side effects with regard to intestinal microbiota, inflammation, oxidative stress and improve the hematological profile when compared to daily oral iron prescription
As a follow-up to the RAPIDIRON Trial (NCT05358509), this study will follow the previously randomized mothers as well as their offspring after birth to assess neurodevelopmental, hematologic, and health outcomes. The study's overarching goal is to determine if the offspring born to RAPIDIRON Trial mothers in the intravenous iron groups, compared to the oral iron group, will achieve superior neurodevelopment, iron stores, and growth at specific time points during the first three years of life. Differences will be assessed between offspring based on the iron deficiency anemia (IDA) treatment of the mother.
One of the most common nutritional deficiencies worldwide is iron deficiency. Iron deficiency is considered the main cause of anaemia in developing countries, including those in South America. The most recent surveys report that the prevalence of anaemia is as high as, 40 and 25% in Peru. Populations living at higher altitudes may have higher iron requirements, as body iron is naturally increased in long-term high-altitude residents to compensate for the lower oxygen in the air at high altitudes. However, the effects of chronic exposure to high altitude on iron status, body iron compartments and dietary iron requirements are incompletely understood. The primary objective of the proposed research is to determine iron bioavailability of iron from biofortified potatoes at different altitudes in populations of Andean descent. Human trials will be undertaken with volunteers in the Huancavelica region of Peru (elevation: 3676 meters) as well as in Lima (elevation close to sea level). The aim is to assess the effect of altitude on the absorption from a promising iron biofortified potato cultivar. These trials require incorporation of iron stable isotopes into the meals of the bio fortified potato and the analysis of the isotopes in subsequent blood (red blood cells) samples. Stable iron istotopes are considered the golden standard to assess human iron absorption and can be safely used as tracer substances in humans. The objective of the study is to compare, in volunteer females of childbearing age, the bioavailability of iron from bio-fortified potatoes in two locations of different altitudes and quantify the effect of altitude on iron bioavailability from a potato meal consumed over 5 consecutive days.
A randomized, placebo controlled, parallel group, double blind study to compare the 3-month adherence and efficacy of Active Iron in subjects with or at-risk of iron deficiency and a history of intolerance to oral iron. Subjects with intolerance and treatment failure due to oral iron (male and female subjects, aged 18 to 55 years, with mild to moderate iron deficiency, with or without anaemia) are eligible. Sixty subjects are randomised into three groups (14 mg elemental iron, 25mg elemental iron and 50mg elemental iron daily). The primary objective is to assess adherence/persistence (including using pill counts). Secondary objectives are to assess gastrointestinal tolerability, haematological efficacy and health related quality of life.
Scoliosis is a condition in which there is curvature of the spine occurring in the lateral plane. It occurs in structural forms, characterized by a fixed curve, and "functional" forms, characterized by a flexible or correctable curve. By anatomic necessity, this lateral deviation is associated with vertebral rotation, such that when this deformity occurs in the thoracic spine, a chest wall deformity, or "rib hump," develops. Often there is a primary structural curve with an adjacent secondary compensatory curve. Most cases of structural scoliosis are idiopathic and have their onset in early adolescence. Females are affected more often than males, and their curvature is more likely to worsen. Lumbar fusion surgery is usually associated with massive blood loss. In clinical practice the surgeon might measure the visible peri-operative bleeding including intra- and post-operative drainage, but ignore blood component penetration into the tissues, residual blood in vertebral canal and loss due to haemolysis, which are also known as hidden blood loss. In patients with adolescent idiopathic scoliosis (AIS), surgical treatment involves a posterior approach with multi-segmental pedicle screw fixation. Although this procedure is generally considered safe with few surgical complications, there are considerable variations in fusion length, surgical time, and the extent of soft-tissue exposure. Consequently, perioperative blood loss can be substantial, and the use of intraoperative and postoperative RBC transfusions are frequently required. Patient blood management (PBM) is an evidence-based, multidisciplinary approach developed over the last 10 years focusing on improving patient outcomes as well as reducing the use of RBC transfusions. PBM includes several preventive measures to manage bleeding risks, reduce iatrogenic blood loss, and modify decision thresholds for the appropriate administration of blood therapy. All patients for elective surgery in whom blood loss is expected to be > 500 ml should have their hemoglobin checked pre-operatively and be investigated if they are found to be anemic. In the general population, anemia is defined as a hemoglobin less than 130 g. in men and less than 120g. in women by the WHO. It was proposed that the cut-off value/trigger be changed to hemoglobin more than 130 g for both men and women. Women with hemoglobin levels between 120 and 129 g. are not considered to be anemic according to the WHO definition, leaving them at a potential disadvantage when undergoing major surgery
Iron deficiency anemia is the leading cause of anemia during pregnancy, which can still reach 10 to 20% of pregnant women in developed countries, with potentially serious consequences for the child. Systematic iron supplementation remains controversial. This study aims to identify in the first trimester of pregnancy clinical and biological predictive factors for the occurrence of iron deficiency anemia in the third trimester of pregnancy.
Intravenous iron preparations have been shown to be superior to oral iron and have largely replaced the treatment of anaemia in Northern countries. However, the socio-economic and medical conditions in low resource countries greatly differ from those in northern countries. Patients' different access to medication supply, perception of medication need and compliance as well as the burden of concomitant disease like malaria, soil-transmitted helminths, schistosomiasis, HIV and red blood cells (RBC) genetic disorders may influence effectiveness and safety of iron substitution modality. The aim of the present study is to compare iv iron substitution by ferric carboxymaltose (Ferinject®) to per oral iron substitution in a low resource country
Complementary feeding diet in developing countries cannot meet iron requirements of infants and young children. Iron supplementation is mostly used to treat iron deficiency whereas iron fortification is cost-effective strategy to control iron deficiency in developing countries. However, a recent study showed that iron fortification imposed negative impact on gut microbiota by increasing colonization of gut pathogen over beneficial bacteria. Gut microbiota plays essential roles in nutrient absorption, vitamin synthesis; intestinal mucosal barrier function and pathogen displacement. Iron is essential for growth and virulence of most gut pathogens and so iron supplementation might have similar negative impact on gut microbiota composition. Therefore, nutrition interventions would not be justified by assessing micronutrient status alone ignoring any possible deterioration of gut microbiota. The investigators hypothesized that optimizing the nutrient intake from locally available foods according to complementary feeding recommendation (CFR) can improve the iron status of these children while maintaining healthy gut microbiota composition. A randomized, placebo-controlled, community-based, intervention trial will be conducted in Ayeyarwady division of Myanmar where childhood undernutrition is prevalent. The aim of this study is to compare the effect of optimized CFR to iron supplementation on iron status and gut microbiota composition of 1-2years old Myanmar children. Cluster randomization will be done at the village level to randomly allocate the villages into CFR or non-CFR villages. Individual randomization will be done to randomly assign each child into iron or placebo syrup so that individual children will receive one of 4 treatment groups (CFR, Fe, CFR + Fe, and Control) for a period of 24 weeks. Based on expected between-groups difference of hemoglobin 5g/L, at 80% power, 5% level of significance, 15% drop-out rate; after taking into account the cluster effect; required sample will be 109 per group (total = 436). A sub-sample of 15 children from each group will be randomly selected for gut microbiota assessment (total = 60). Blood samples for iron status and stool samples for gut microbiota assessment will be collected at baseline and endline. Anthropometric measurements, usual intake of iron and infectious disease morbidity will also be assessed.
The long-term goal is to assess the fall in kidney function measured by glomerular filtration rate (GFR) when patients with chronic kidney disease (CKD) are exposed to intravenous iron (IVIR). We hypothesize that in subjects with mild to moderate CKD, infusion of intravenous iron (IVIR), will generate oxidative stress and cause an inflammatory response that will be associated with a more rapid decline in glomerular filtration rate (GFR) compared to oral iron.
