Filter by:Iron deficiency has been reported in approximately 35% of patients with a gynecologic malignancy. Blood transfusions are known to be immunosuppressive and carry immediate and long-term risks. Pre-operative blood transfusion in gynecologic oncology patients is associated with higher rates of surgical site infection, length of stay, composite morbidity, cancer recurrence, and mortality. Pre-operative intravenous iron formulations have been shown in benign gynecology and other surgical specialities to increase pre-operative hemoglobin and decrease post-operative transfusion rates. This is a randomized double-blinded clinical trial evaluating the effects of treating patients undergoing gynecologic oncology surgery with intravenous ferric derisomaltose to correct pre-operative iron-deficiency anemia. The study aims to assess the effectiveness of preoperative ferric derisomaltose/iron isomaltoside compared to placebo in correcting preoperative hemoglobin in patients undergoing surgery for gynecologic malignancy.
The objective of our work is to predict the value of ferritin from the eye, thus constituting an original, non-invasive diagnostic method of iron deficiency. To be usable in real life, the algorithm must be comparable to the performance of the reference diagnostic test (determination of ferritin), allowing to obtain a sensitivity of about 90% and a specificity > 95%.
To obtain up-to-date data on nutritional status of older adults, a national dietary survey will be conducted in 2022/2023, providing data on the consumption of foods and enabling the assessment intakes of energy and specific nutrients. Participating subjects will be also screened for micronutrient status using blood biomarkers (focusing into vitamin D, folic acid, vitamin B12, and iron).
In this phase II trial, the investigators overarching goal is to demonstrate the feasibility and potential benefit of darbepoetin (Darbe) plus slow-release intravenous (IV) iron to decrease transfusions, maintain iron sufficiency and improve the neurodevelopmental outcomes of preterm infants. Investigators hypothesize that in infants < 32 completed weeks of gestation, combined treatment with Darbe plus Ferumoxytol (FMX) or Darbe plus low molecular weight iron dextran (LMW-ID) will: 1) be safe, 2) decrease or eliminate transfusions, 3) maintain iron sufficiency, 4) result in higher hematocrit and 5) improve neurodevelopment. Investigators further hypothesize that when compared to oral iron supplementation (standard care), IV iron will be better tolerated, with less effect on the gastrointestinal (GI) microbiome
Due to the growing world population, there is a need to develop viable ecological and nutritional alternatives to animal food products. However, animal products are a key dietary source of well-absorbed iron, and iron deficiency and iron deficiency anemia remain highly prevalent in high- and low-income countries. Meat and fish provide a substantial proportion of absorbed iron in the western diet by two distinct components: a) heme iron is well absorbed (20-45% fractional absorption) and is not affected by most dietary enhancers and inhibitors, which often affect non-heme iron absorption; b) peptides in muscle meat exert an enhancing effect the absorption of non-heme iron contained in other meal components. The potential of edible insects as a dietary source of well-absorbed iron has not been investigated in detail. In particular, it is unclear whether insects provide an iron moiety similar to hemoglobin which would be well absorbed and unaffected by other dietary components, and whether their presence in a test meal exerts an enhancing effect on iron bioavailability from the whole meal. To differentiate iron absorption from insect biomass from other sources, insects will be intrinsically labelled with the stable iron isotope 57Fe, while other food iron components will be labelled with the iron isotope 58Fe.The present studiy will provide novel data to elucidate the nutritional value as sources of dietary iron of insect species Xylotrupes gideon. X. gideon is an insect species traditionally widely consumed in SubSaharan Africa and South East Asia and recognised by FAO as an edible insect species. X gideon is produced in ZHAW facilities in Linthal, Switzerland under controlled conditions aiming to a highly sustainable and high nutritional value food product. Furthermore the benefit of ascorbic acid addition to X.gideon biomass on iron absorption will be quantified.
The World Health Organization recommends daily iron supplementation for infants and children (6 months-12 years). Based on the low cost and high bioavailability and efficacy, ferrous sulfate is typically the first choice for supplementation and fortification. The recommended dose of iron is set high to deliver adequate absorbed iron due to low rates of dietary iron absorption, which is typically <10%. Thus, the majority of dietary iron is not absorbed and travels to the colon. Unabsorbed iron in the colon may select for enteric pathogens at the expense of beneficial commensal bacteria and increase infection risk, including the clinical incidence of diarrhea. The objective of this study is to compare the effects of iron as ferrous sulfate (FeSO4) or FeSO4-enriched Aspergillus oryzae (Ao iron) on the growth and virulence of common enteric pathogens using an in vitro fecal fermentation model. Stool samples will be collected from children following ingestion of an iron supplement as either FeSO4 or Ao iron. Stool samples will be spiked with common enteric pathogens and outcome measures will be determined following in vitro fecal fermentation.
The OPERA-MI trial evaluates the effect of i.v. ferric carboxymaltose compared to the effect of oral iron, on left ventricular systolic function.
Iron is very important for our body and performs vital tasks. Iron deficiency is a worldwide health problem. The prevalence of anemia in women of reproductive age in Southeast Asia is estimated to be 46.6% in 2019, with iron deficiency being one of the main reasons for anemia. There are different approaches to treat iron deficiency. One of them is the use of iron supplements. Recommended iron supplement treatments today often differ in dose, regimen and length. Experts recommend a dose of 80-200 mg of iron taken either daily or on several days per week, depending on the severity of the iron deficiency (with or without anemia). From certain guidelines lower amounts of iron are also recommended, as this could lead to fewer side effects.Previous studies have shown that both daily and multiple days per week administration can be effective in treating iron deficiency. Recently, several successive iron supplementation studies in Zurich showed that 24 h after ingestion of an oral dose of >60mg iron, the absorption of iron in the body is impaired. In addition it was measured that iron supplements taken only every other day instead of every day are absorbed about 30-50% better and have fewer side effects. Little is known about the long-term effect of this alternating regimen on iron status and side effects.With this 6-months study in the Philippines, the investigators want to compare two different supplementation regimens with oral iron to see if there is any difference in the iron status, intestinal inflammation levels, and side effects, and therefore if it would be better to take the iron supplements every 2 days instead of daily.
The serum or plasma ferritin concentration (referred to hereafter as ferritin) is the most widely used indicator to detect iron deficiency and a low ferritin indicates depleted iron stores. However, the threshold ferritin that defines iron deficiency remains unclear and diagnostic ferritin cutoffs from expert groups vary widely. Our study aim is to define the ferritin in Kenyan young women at which the body senses iron depletion and begins to upregulate iron absorption from the diet; this approach could provide a functionally defined threshold of iron deficiency in Sub-Saharan African women.
The primary aim of this retrospective, monocentric study with two parallel groups is to investigate pregnancy outcome in women with iron deficiency in the first trimester. It compares the pregnancy outcome between pregnant women with an iron deficiency and those without an iron deficiency in the first trimester. The study group are pregnant women with a diagnosed iron deficiency in the first trimester, a total of 227 pregnant women. The control group consists of 486 pregnant women without first-trimester iron deficiency. Matching criteria include parity and maternal age. Data from patient files of pregnant women who were treated in the Women's Clinic, University Hospital Basel between 2017 and 2019 are analyzed.
