AIMS: Among persons with prevalent heart failure (HF), iron deficiency has been linked to HF admissions, and intravenous iron replacement improves HF outcomes. Recent studies in persons with chronic kidney disease (CKD) demonstrate that iron deficiency is associated with incident HF. This study aimed to determine the relationship of iron status with incident HF in community-dwelling older adults irrespective of their kidney function. METHODS: In this case-cohort study, 1,006 Cardiovascular Health Study participants (785 from the random sub-cohort [including 193 HF cases] and 221 additional HF cases [N = 414 total HF cases]) aged ≥ 65 years without HF (41% with CKD), we used weighted Cox models to evaluate associations of iron status with incident HF. Participants were categorized based on quartiles of transferrin saturation and ferritin as iron replete (27.3%), functional iron deficiency (7.7%), iron deficiency (11.8%), mixed iron deficiency (5.6%), high iron (9.3%) and non-classified (38.1%), consistent with prior studies. RESULTS: Compared to older persons who were iron replete, those with iron deficiency were at higher risk of incident HF (HR 1.47; 1.02-2.11) in models adjusting for demographics, HF risk factors, and estimated glomerular filtration rate. Other iron categories did not associate with incident HF. The relationship of iron deficiency with incident HF did not differ by CKD status (interaction P value 0.2). CONCLUSIONS: Among community-dwelling elders, iron deficiency is independently associated with incident HF, an association that was similar irrespective of CKD status. Our findings support conduct of clinical trials of iron replacement for prevention of HF in older adults with iron deficiency.

Animal flesh foods are rich in bioavailable iron but infrequently consumed by young children. We aimed to determine whether flesh food intake was associated with iron and anaemia status among 585 Malawian infants enroled in a 6-month egg-feeding trial. The percentage of days of small fish, large fish and meat consumption were assessed through weekly 7-day animal-source food screeners. Grams of intake were assessed through 24-h recalls conducted at 6-9, 9-12 and 12-15 months of age. Plasma ferritin, soluble transferrin receptor (sTfR) and haemoglobin concentrations were measured at 6-9 and 12-15 months of age. Iron biomarkers were adjusted for inflammation during analysis. At enrolment, each flesh food category was consumed by

BACKGROUND: Murine data suggest that the placenta downregulates ferroportin (FPN) when iron is limited to prioritize iron for its own needs. Human data on the impact of maternal and neonatal iron status on placental FPN expression are conflicting. OBJECTIVES: This study aimed to identify determinants of placental FPN protein abundance and to assess the utility of the placental iron deficiency index (PIDI) as a measure of maternal/fetal iron status in newborns at high risk for anemia. METHODS: Placental FPN protein abundance was measured by western blots in placentae collected from 133 neonates born to adolescents (17.4 ± 1.1 y) carrying singletons (delivery gestational age [GA]: 39.9 ± 1.3 wk) and from 130 neonates born to 65 females (30.4 ± 5.2 y) carrying multiples (delivery GA: 35.0 ± 2.8 wk). Placental FPN and the PIDI (FPN:transferrin receptor 1) were evaluated in relation to neonatal and maternal iron-related markers (hemoglobin [Hb], serum ferritin [SF], soluble transferrin receptor [sTfR], total body iron [TBI], hepcidin, erythropoietin [EPO], erythroferrone). RESULTS: FPN protein was detected in all placentae delivered between 25 and 42 wk GA. Placental FPN protein abundance was associated with neonatal iron and erythropoietic markers (EPO: β: 0.10; 95% confidence interval [CI]: 0.06, 0.35; sTfR: β: 0.20; 95% CI: 0.03, 0.18; hepcidin: β: -0.06; 95% CI: -0.13, -0.0003; all P < 0.05). Maternal sTfR was only indirectly associated with placental FPN, with neonatal sTfR as the mediator (β-indirect: 0.06; 95% CI; 0.03, 0.11; P = 0.003). The PIDI was associated with neonatal Hb (β: -0.02; 95% CI: -0.03, -0.003), EPO (β: 0.07; 95% CI: 0.01, 0.14), and sTfR (β: 0.13; 95% CI: 0.004, 0.3) and with maternal SF (β: 0.08, 95% CI: 0.02, 0.14), TBI (β: 0.02; 95% CI: 0.009, 0.04), EPO (β: -0.10; 95% CI: -0.19, -0.01), sTfR (β: -0.16: 95% CI: -0.27, -0.06), and hepcidin (β: 0.05; 95% CI: 0.002, 0.11) at delivery (all P < 0.05). CONCLUSIONS: Placental FPN abundance was positively associated with neonatal indicators of increased erythropoietic activity and poor iron status. The PIDI was associated with maternal and neonatal iron-related markers but in opposite directions. More data are needed from a lower-risk normative group of females to assess the generalizability of findings. These trials were registered at clinicaltrials.gov as NCT01019902 and NCT01582802.

Anaemia among women and young children remains a major public health concern. This secondary study describes the anaemia prevalence among young hospitalised children and their mothers in northern Lao Peoples Democratic Republic and explores possible nutritional causes and risk factors for anaemia. Hospitalised children (ages 21 days to

ABSTRACT: Background: About a third of the world's population is estimated to suffer from anaemia, and iron deficiency is expected to account for about half of all anaemia cases. This study was designed to get an estimate of the proportion of patients with iron deficiency anaemia (IDA) who have a significant gastrointestinal (GI) pathology, in particular a GI malignancy, and to identify any risk factors or predictors for the same. Methods: This cross-sectional study was conducted at a hospital in Eastern India. The study population comprised males above the age of 18 and postmenopausal females with IDA, excluding those haemodynamically unstable or with chronic diseases. Data collection included a detailed history, sociodemographic details, dietary habits, GI symptoms, and severity of anaemia. Faecal occult blood tests (OBTs) were conducted, and patients were referred for upper and lower GI endoscopy with biopsies. Results: Out of the 257 patients, 50.97% (n = 131) had a significant GI pathology, and 25.68% (n = 66) had a GI malignancy. Male gender (AOR: 5.203, 95% CI: 1.725–15.698) and a positive stool OBT (AOR: 6.516, 95% CI: 2.255–18.828) were found to be independent risk factors for any GI pathology. Age 40 years or above (AOR: 11.376, 95% CI: 1.199–107.946), loss of appetite (AOR: 15.548, 95% CI: 1.416–170.735), pain abdomen (AOR: 5.566, 95% CI: 1.149–26.953), dysphagia (AOR: 7.945, 95% CI: 1.036–60.915), family history of malignancy (AOR: 46.726, 95% CI: 4.076–535.645), and positive OBT (AOR: 22.430, 95% CI: 3.933–127.915) were found to be independent risk factors of GI malignancy. Conclusions: This study shows that a large proportion of adult males and postmenopausal females presenting with IDA in India have significant GI pathology. Furthermore, a significant proportion of them have GI malignancies. Thus, bidirectional endoscopy should be considered for these patients. Male patients, age >40, those with history of loss of appetite or weight, pain abdomen or dysphagia, positive family history, and positive OBT should be prioritised for the investigation.

Objectives: Delays in the evaluation and treatment of iron deficiency can lead to increased disease‐related morbidity and mortality. Electronic consultation (e‐consult) is a referral modality that allows providers quicker access to recommendations from a specialist based on electronic chart review. While the use of e‐consult is expanding in classical hematology, gaps exist in the understanding of patient outcomes related to its use for iron deficiency. Methods: We randomly selected 200 e‐consults and 200 traditional referrals from 3,336 hematology referrals for iron deficiency at a single center. The primary outcomes of the retrospective analysis were: time to completion of the referral, and time to treatment with intravenous iron. Secondary outcomes included recurrence of iron deficiency, need for repeat e‐consult, conversion to in‐person evaluation, and assessment of whether the etiology of iron deficiency was addressed. Results: E‐consults significantly reduced the time from referral to intravenous iron repletion (e‐consult, 33 days; traditional referral, 68 days; p <.05). Assessment of the underlying etiology occurred in 70.7% of the e‐consult encounters compared to 92.5% of traditional referrals (p <.05). Conclusions: These findings highlight advantages of e‐consults in improving care delivery in iron deficiency, and identifying gaps that can be improved through practice standardization to ensure equitable, high‐value care.

Accurate and timely interpretation of microcytic anemia can be diagnostically challenging in the primary care setting. We sought to develop a novel model for distinguishing iron-deficiency anemia from thalassemia trait in the modern pediatric population. Demographic history and red blood cell indices were retrospectively characterized for 76 children referred to our pediatric hematology clinic for evaluation of microcytic anemia. Statistically significant variables were sequentially added into a logistic regression model to develop the final model. The final discriminating model incorporates red cell distribution width, mean corpuscular hemoglobin concentration, and red blood cell values. Favorable predictive performance is seen in the initial (sensitivity 89.2%, specificity 92.3%) and external validation cohort (sensitivity 84.4%, specificity 88.9%). This novel tool may aid in determining the cause of hypochromic, microcytic anemia in the primary care setting. Finally, the study cohort reflects an underrepresented group in the development of screening tools, and thus offers generalizability. [ABSTRACT FROM AUTHOR]

Background: Anemia is considered as one of the risk factors affecting the outcomes after cardiac surgery. Accordingly, the improvement of iron deficiency anemia through injection or oral may be associated with the improvement of post-procedure results, especially the improvement of cardiovascular function. This study was aimed at investigating the effectiveness of iron treatment shortly before surgery in reducing the need for blood transfusion and improving myocardial performance parameters (left ventricular ejection fraction) in coronary bypass surgery patients. Methods: This study was a single-blind randomized clinical trial. In total, 60 candidates for coronary bypass surgery having iron deficiency anemia before the operation were randomly divided into two groups treated with injectable iron supplement (iron sucrose at a dose of 200 mg/200 ml of normal saline injected in 30 minutes) 48 to 72 hours before surgery or without therapeutic intervention. The patients were examined during and after the operation in terms of surgical outcomes. Results: Treatment with injectable iron before surgery was associated with improvement in serum hemoglobin level after surgery and a significant reduction in the need for intraoperative and postoperative transfusions. Preoperative treatment of iron deficiency was associated with a reduction in the length of hospitalization of the patients after surgery. Conclusion: Treatment of iron deficiency anemia within 48 to 72 hours before surgery will improve the condition of patients’ anemia and compensate serum hemoglobin, reduce the need for blood transfusion during surgery and the length of hospitalization of the patients after surgery.

Male patients, age >40, those with history of loss of appetite or weight, pain abdomen or dysphagia, positive family history, and positive OBT should be prioritised for the investigation.

Micronutrient deficiencies result in a broad range of adverse health and functional consequences, but the true prevalence of specific deficiencies remains uncertain because limited information is available from nationally representative surveys using recommended biomarkers. The present review compares various reported national deficiency prevalence estimates for nutrients and years where the estimates overlap for individual countries that conducted nationally representative surveys and explores possible reasons for any discrepancies discovered. Nationally representative micronutrient status surveys that were conducted since 2000 among preschool-aged children or women of reproductive age and included assessment of iron, vitamin A, or zinc status based on recognized biomarkers were considered eligible for inclusion, along with any modeled deficiency prevalence estimates for these same countries and years. There was considerable variation across different published prevalence estimates, with larger inconsistencies when the prevalence estimate was based on proxies, such as hemoglobin for iron deficiency and dietary zinc availability for zinc deficiency. Numerous additional methodological issues affected the prevalence estimates, such as which biomarker and what cutoff was used to define deficiency, whether the biomarker was adjusted for inflammation, and what adjustment method was used. For some country-years, the various approaches resulted in fairly consistent prevalence estimates. For other country-years, however, the results differed markedly and changed the conclusions regarding the existence and severity of the micronutrient deficiency as a public health concern. In conclusion, to determine micronutrient status, we consider the assessment of one of the recommended biomarkers in a population representative survey as the best available information. If indicated, results should be adjusted for inflammation and generally acceptable cutoffs should be applied to facilitate comparisons, although individual countries may also apply nationally defined cutoffs to determine when and where to intervene. Global consensus is needed on best practices for presenting survey results and defining the prevalence of deficiency.

Purpose: Anemia is an important problem of public health that is widespread throughout the world. Although there are many different causes of anemia, nutritional causes are the most common. The aim of this study is to investigate the types of nutritional anaemias seen between the ages of 6 months and 18 years, and the characteristics affecting these anaemias in our province. Materials and Methods: Cases diagnosed with nutritional anaemia in the paediatric outpatient clinics between 2019and 2021 were included. Results: A total of 2187(51.9%) of the cases were girls and 1375(32.6%) were adolescents. Of 4217 subjects, 3110(73.7%) had microcytic, 781(18.5%) had megaloblastic and 326(7.7%) had mixed type anaemia. Girls had a higher total iron-binding capacity (368.6±57.5 vs. 361.7±56.9, p=0.013). Vitamin 25(OH)D serum levels were lower in megaloblastic and mixed anaemia than in microcytic anaemia (11.7 (2.3-66.7) vs. 13.9 (2.1-102), p

Many drastic actions are taken by cocaine users for the sake of experiencing high levels of dopamine, which depends on iron for its synthesis. Dopamine depletion and iron deficiency are also involved in the symptoms of restless leg syndrome (RLS). The intersecting biochemical pathways of cocaine use, iron deficiency, and RLS have not been adequately investigated. This case report reveals the successful treatment of a patient experiencing these conditions. A 63-year-old male with a history of cocaine use disorder, insomnia, and RLS sought emergency care for suicidality. Upon admission, he was also found to be iron deficient. He revealed that his RLS worsened when he attempted to abstain from cocaine. He also used alcohol to sustain the effects of cocaine when the cost of cocaine was too high. During hospitalization, his mood, cravings, and RLS were resolved with adjunctive iron supplementation, as well as treatment with 300 mg of Wellbutrin (bupropion hydroxychloride). If iron deficiency is present, the replenishment of the adequate dopaminergic receptor density and function via supplementation may play an essential role in the prevention of cocaine use and the cessation of cocaine withdrawal symptoms. Further research is warranted to validate these findings and to investigate the implications of iron supplementation in addiction medicine. [ABSTRACT FROM AUTHOR]

TMPRSS6 is a serine protease highly expressed in the liver. Its role in iron regulation was first reported in 2008 when mutations in TMPRSS6 were shown to be the cause of iron-refractory iron deficiency anemia (IRIDA) in humans and in mouse models. TMPRSS6 functions as a negative regulator of the expression of the systemic iron-regulatory hormone hepcidin. Over the last decade and a half, growing understanding of TMPRSS6 biology and mechanism of action has enabled development of new therapeutic approaches for patients with diseases of erythropoiesis and iron homeostasis.ClinicalTrials.gov identifier NCT03165864.

Background:    Childhood cancer may be related to maternal health in pregnancy. Maternal anemia is a common condition in pregnancy, especially in low-income countries, but the association between maternal anemia and childhood cancer has not been studied using a nationally representative population. Objective:        To examine the potential relation between maternal anemia during pregnancy and childhood cancers in a population-based cohort study in Taiwan. Methods:         We examined the relationship between maternal anemia and childhood cancer in Taiwan (N= 2160 cancer cases, 2,076,877 non-cases). Cases were taken from the National Cancer Registry, and non-cases were selected from national records. Using national health registries, we obtained maternal anemia diagnoses. We estimated the risks for childhood cancers using Cox proportional hazard analysis. Results:           There was an increased risk of cancers in children born to mothers with nutritional anemia (Hazard Ratio (HR): 1.32, 95% CI 0.99, 1.76). Iron deficiency anemia (HR: 1.30, 95% CI 0.97-1.75) carried an increased risk, while non-nutritional anemias were not associated with childhood cancer risk. Conclusion:     Our results provide additional support for screening for anemia during pregnancy. Adequate nutrition and vitamin supplementation may help to prevent some childhood cancer cases.

BackgroundGrowing evidence suggests low and high maternal hemoglobin (Hb) concentrations may have adverse consequences for maternal and child health. There remain questions on specific Hb thresholds to define anemia and high Hb as well as how cutoffs may vary by anemia etiology and timing of assessment.MethodsWe conducted an updated systematic review (using PubMed and Cochrane Review) on low (

Purpose: About 40% of pregnant women are anemic and at an increased risk for complications. We examined the efficacy of inpatient anemia workup and treatment in pregnant women diagnosed with moderate-severe anemia (hemoglobin < 10 mg/dL), during hospitalization in the late second-trimester and third-trimester. Methods: This retrospective study, conducted between March 2020 and November 2022, included women at ≥ 24 gestational weeks who were hospitalized due to various indications and diagnosed with anemia (hemoglobin < 10 mg/dL). The study group comprised women who underwent an inpatient anemia workup and initiation of anemia treatment. The comparison group comprised women who did not undergo an inpatient anemia investigation. The primary outcome was the rate of pre-delivery hemoglobin > 11 g/dL. Results: The most frequent etiology of anemia in the study group (n = 188) was iron-deficiency anemia (30.2%), followed by mixed anemia of iron, folate and vitamin-B12 deficiencies (20.7%). In the study vs. the comparison group (n = 179), the rate of pre-delivery hemoglobin > 11 g/dL was higher, and the increase in hemoglobin from intervention to delivery was greater. The ideal timing for anemia intervention for maximizing the increase in pre-delivery hemoglobin was 6-weeks or more prior to delivery. The rates of postpartum hemorrhage and blood transfusions were similar. The rate of postpartum hemoglobin < 10 g/dL was lower in the study than the comparison group. Conclusion: Inpatient anemia investigation and treatment resulted in higher peri-delivery hemoglobin. In women randomly diagnosed with anemia at hospitalization, the rate of pre-delivery hemoglobin > 11 g/dL was increased among those who underwent a simple anemia investigation and treatment initiation.

BACKGROUND: Micronutrient deficiencies compromise immune systems, hinder child growth and development, and affect human potential worldwide. Yet, to our knowledge, the only existing estimate of the global prevalence of micronutrient deficiencies is from over 30 years ago and is based only on the prevalence of anaemia. We aimed to estimate the global and regional prevalence of deficiency in at least one of three micronutrients among preschool-aged children (aged 6-59 months) and non-pregnant women of reproductive age (aged 15-49 years). METHODS: In this pooled analysis, we reanalysed individual-level biomarker data for micronutrient status from nationally representative, population-based surveys. We used Bayesian hierarchical logistic regression to estimate the prevalence of deficiency in at least one of three micronutrients for preschool-aged children (iron, zinc, and vitamin A) and for non-pregnant women of reproductive age (iron, zinc, and folate), globally and in seven regions using 24 nationally representative surveys done between 2003 and 2019. FINDINGS: We estimated the global prevalence of deficiency in at least one of three micronutrients to be 56% (95% uncertainty interval [UI] 48-64) among preschool-aged children, and 69% (59-78) among non-pregnant women of reproductive age, equivalent to 372 million (95% UI 319-425) preschool-aged children and 1·2 billion (1·0-1·4) non-pregnant women of reproductive age. Regionally, three-quarters of preschool-aged children with micronutrient deficiencies live in south Asia (99 million, 95% UI 80-118), sub-Saharan Africa (98 million, 83-113), or east Asia and the Pacific (85 million, 61-110). Over half (57%) of non-pregnant women of reproductive age with micronutrient deficiencies live in east Asia and the Pacific (384 million, 279-470) or south Asia (307 million, 255-351). INTERPRETATION: We estimate that over half of preschool-aged children and two-thirds of non-pregnant women of reproductive age worldwide have micronutrient deficiencies. However, estimates are uncertain due to the scarcity of population-based micronutrient deficiency data. FUNDING: US Agency for International Development.

Background and Objectives Regular blood donors may experience iron deficiency due to repeated blood donation. Genetic differences might have an impact on iron deficiency in regular blood donors. Some of these genes include those involved in activities related to iron absorption and transfer in blood. In this study, the association of the rs855791 single nucleotide polymorphism in TMPRSS6 gene with iron levels in male regular blood donors was investigated. Materials and Methods In this cross-sectional study, 130 male regular blood donors participated. CBC tests, serum iron, ferritin, and Total Iron Binding Capacity (TIBC) were performed on their blood samples. The genotypes of the target polymorphisms were determined using the allele-specific PCR method. All collected data were analyzed using R software for statistical analysis. Results The average age of the regular male blood donors was 45 years with a standard deviation of 10.5. Among the 130 regular blood donors, 28 individuals (21.54%) were homozygous for the T/T allele, 29 individuals (22.31%) were homozygous for the C/C allele, and 73 individuals were heterozygous for the C/T allele. No significant association was observed between the rs855791 single nucleotide polymorphism and iron assessment indicators. Conclusions Single nucleotide polymorphism of TMPRSS6 gene (rs855791 v736A) was not associated with iron level and related quantities in regular blood donors. [ABSTRACT FROM AUTHOR]

Objective: The aim of this study was to investigate the association between iron deficiency anemia and sleep duration in the first year of life. Methods: A total of 123 infants were investigated, with sleep being evaluated at 3, 6, and 12 months of age and anemia at birth and 6 months. The cutoff points for anemia and short sleep duration were hemoglobin <11 g/dL (at birth and/or 6 months) and <10 h (at 3, 6, and 12 months), respectively. The comparison of the average sleep time between infants with and without anemia was performed using the Student’s t-test, and logistic regression models were also used to verify differences in the sleep duration (short/not short) between the groups. Linear regression analyses were conducted to determine the association between sleep duration and hemoglobin values. The analyses were adjusted for potential confounders. Results: Children with anemia were more likely to be short sleepers [odds ratio (95% confidence interval (CI)): 4.02 (1.02– 15.76); p≤0.05], and for each unit increase in hemoglobin values, the sleep duration increased by 16.2 min [β (95%CI): 0.27 (0.00– 0.55); p≤0.05), regardless of family income, maternal schooling, gender, and body mass index at birth. Conclusions: Our results suggest that iron deficiency anemia is associated with short sleep duration in the first year of life and indicate the need for longitudinal investigations, with longer follow-up, to verify the impact of anemia on sleep duration at subsequent ages.

Antenatal multiple micronutrient supplements (MMS) are more effective than iron and folic acid (IFA) supplements in reducing adverse pregnancy outcomes. Questions remain, however, about the ability of MMS to prevent anemia as effectively as IFA, especially at a lower dose of daily iron and in areas of high anemia prevalence. Analyzing data from 11 trials from a recent Cochrane review, we compared MMS to IFA, delivering either 30 or 60 mg of iron, in sustaining hemoglobin and preventing third trimester anemia and iron deficiency anemia (IDA), accounting for daily iron dose, total supplemental iron intake, and baseline prevalence of anemia. There were no differences between MMS and IFA in third trimester hemoglobin concentration or risks of anemia or IDA by iron dose or total supplemental iron consumed. MMS providing 30 mg of iron was comparable to IFA with 60 mg of iron: mean hemoglobin difference of -0.26 g/L (95% CI: -1.41 to 0.89), risk ratios of 0.99 (95% CI: 0.92-1.07) for anemia, and 1.31 (95% CI: 0.66-2.60) for IDA. Baseline prevalence of anemia did not explain heterogeneity in findings. Compared to IFA, MMS results in comparable hemoglobin concentration and protection against anemia during pregnancy, independently of iron dose.

Ferric citrate is approved as an iron replacement product in patients with non-dialysis chronic kidney disease and iron deficiency anemia. Ferric citrate-delivered iron is enterally absorbed, but the specific mechanisms involved have not been evaluated, including the possibilities of conventional, transcellular ferroportin-mediated absorption and/or citrate-mediated paracellular absorption. Here, we first demonstrate the efficacy of ferric citrate in high hepcidin models, including Tmprss6 knockout mice (characterized by iron-refractory iron deficiency anemia) with and without adenine diet-induced chronic kidney disease. Next, to assess whether or not enteral ferric citrate absorption is dependent on ferroportin, we evaluated the effects of ferric citrate in a tamoxifen-inducible, enterocyte-specific ferroportin knockout murine model (Villin-Cre-ERT2, Fpnflox/flox). In this model, ferroportin deletion was efficient, as tamoxifen injection induced a 4000-fold decrease in duodenum ferroportin mRNA expression, with undetectable ferroportin protein on Western blot of duodenal enterocytes, resulting in a severe iron deficiency anemia phenotype. In ferroportin-deficient mice, three weeks of 1% ferric citrate dietary supplementation, a dose that prevented iron deficiency in control mice, did not improve iron status or rescue the iron deficiency anemia phenotype. We repeated the conditional ferroportin knockout experiment in the setting of uremia, using an adenine nephropathy model, where three weeks of 1% ferric citrate dietary supplementation again failed to improve iron status or rescue the iron deficiency anemia phenotype. Thus, our data suggest that enteral ferric citrate absorption is dependent on conventional enterocyte iron transport by ferroportin and that, in these models, significant paracellular absorption does not occur.

Abstract Background Iron deficiency (ID) is the most common nutritional disorder affecting all age groups. Infants and young children are vulnerable to anemia especially iron deficiency anemia (IDA), which represents a public health problem with defined impacts on the health of communities. IDA, however, is a preventable and treatable condition; therefore, early diagnosis represents the cornerstone in protection from its adverse consequences and combating its contributing factors. Several international guidelines for the management of ID/IDA are available, however national guidelines that can be implemented and suits our local needs are lacking. Objective To adapt the pre-existing high-quality practice guidelines for the screening, prevention and management of ID/IDA in different pediatric age groups, to be available for the national use by general practitioners, pediatricians, and other health care professionals. Results The adaptation group for this guideline included key leaders from different Egyptian institutions. The panel used the ADAPTE methodology for adaptation of guidelines. The panel prioritized the health questions and recommendations according to their importance for clinicians and patients. The procedure included searching for existing guidelines, quality appraisal, and adaptation of the recommendations to the target context of use. The guideline covered all important aspects of detection, identification of infants, children, and adolescents at high risk of developing ID/IDA, proper management, and prevention. The final version of the adapted clinical practice guideline has been made after thorough review of an external review panel and was guided by their official recommendations and modifications. Implementation tools included algorithms, tables, and flow charts to aid decision making in practice, as well as patient-directed information in the Arabic language. Conclusions This adapted guideline serves as a tool for the screening, prevention and management of ID/IDA in different pediatric age groups.

Diaphragm disease (DD) is a rare condition that is associated with the use of nonsteroidal anti-inflammatory drugs. It is characterized by multiple diaphragm-like septa that cause a narrowing of the small bowel lumen. The diagnosis of this disorder can be challenging due to its rarity and its non-specific symptoms, which often suggest other, more probable diseases. We report the case of a 16-year-old boy who presented with iron-deficiency anemia that did not respond to iron supplementation. Despite undergoing endoscopy and computed tomography (CT) enterography, the cause of his condition could not be identified. Capsule endoscopy was attempted, but due to technical difficulties, images could not be obtained. Two years later, the patient's symptoms persisted, prompting further investigation. CT enterography revealed a foreign body in the distal ileum, which was identified as the previously administered capsule. Diagnostic laparoscopy with intraoperative endoscopy was performed to retrieve the capsule. This procedure also revealed multiple short-segment strictures causing luminal narrowing and ulcerations. These were confirmed by histopathology to be lesions associated with DD.

Infants are frequently supplemented with iron to prevent iron deficiency, but iron supplements may have adverse effects on infant health. Although iron supplements can be highly effective at improving iron status and preventing iron deficiency anemia, iron may adversely affect growth and development, and may increase risk for certain infections. Several reviews exist in this area; however, none has fully summarized all reported outcomes of iron supplementation during infancy. In this review, we summarize the risks and benefits of iron supplementation as they have been reported in controlled studies and in relevant animal models. Additionally, we discuss the mechanisms that may underly beneficial and adverse effects.

Young children in resource-constrained settings are susceptible to zinc deficiency and its deleterious health effects. The objective of this secondary analysis was to evaluate the effects of the following six interventions on biomarkers of iron and zinc status among a subgroup of young children in Dhaka, Bangladesh, who participated in the Zinc in Powders Trial (ZiPT): (1) standard micronutrient powders (MNPs) containing 4.1 mg zinc and 10 mg iron, daily; (2) high-zinc (10 mg) and low-iron (6 mg) (HiZn LoFe) MNP, daily; (3) HiZn (10 mg) and LoFe (6 mg)/HiZn (10 mg) and no-iron MNPs on alternating days; (4) dispersible zinc tablet (10 mg), daily; (5) dispersible zinc tablet (10 mg), daily for 2 weeks at enrollment and at 12 weeks; (6) placebo powder, daily. At the end of the 24 week intervention period, children in the daily dispersible zinc tablet group exhibited a mean serum zinc concentration (SZC) of 92.5 μg/dL, which was significantly higher than all other groups except the HiZn LoFe MNP alternating group (81.3 μg/dL). MNPs containing 10 mg and 6 mg of iron had a similar impact on biomarkers of iron status, with no evidence of an adverse interaction with zinc.

BackgroundSmall-quantity lipid-based nutrient supplements (SQ-LNSs) have been shown to reduce the prevalence of child anemia and iron deficiency, but effects on other micronutrients are less well known. Identifying subgroups who benefit most from SQ-LNSs could support improved program design.ObjectivesWe aimed to identify study-level and individual-level modifiers of the effect of SQ-LNSs on child hemoglobin (Hb), anemia, and inflammation-adjusted micronutrient status outcomes.MethodsWe conducted a 2-stage meta-analysis of individual participant data from 13 randomized controlled trials of SQ-LNSs provided to children 6-24 mo of age (n = 15,946). We generated study-specific and subgroup estimates of SQ-LNSs compared with control, and pooled the estimates using fixed-effects models. We used random-effects meta-regression to examine potential study-level effect modifiers.ResultsSQ-LNS provision decreased the prevalence of anemia (Hb < 110 g/L) by 16% (relative reduction), iron deficiency (plasma ferritin < 12 µg/L) by 56%, and iron deficiency anemia (IDA; Hb < 110 g/L and plasma ferritin 12 mo and provided 9 (as opposed to

The primary nutritional concern among adolescent girls is iron-deficiency anemia, which requires prompt attention to prevent complications during pregnancy. One of the strategies for prevention involves the consumption of iron supplements (IS) and high-iron foods. This study aims to delineate the menstrual history, eating patterns, and practice associated with consuming IS and high-iron foods. Employing a descriptive approach, the research was conducted at Islamic Senior High School (MAN 2) Kudus. The sample, comprising 184 individuals, was selected through purposive sampling. The research employed a questionnaire and a Food Frequency Questionnaire (FFQ) as instruments. The findings indicate that only 19.6% of the respondents reported having IS always available at home. The majority (62.0%) had consumed IS at some point. However, only 8.1% consumed IS regularly during menstruation, and 4.3% consumed it regularly when not menstruating. The majority of respondents frequently consumed high-iron foods (1-5 times per week), including chicken/duck (84.8%), eggs (80.4%), fish (76.7%), and meat (60.9%). It is hoped that schools and local healthcare services can enhance educational efforts regarding the benefits of IS consumption for adolescent girls. The practice of consuming IS and high-iron foods from halal sources are a part of maintaining bodily health and constitutes an obligation for every Muslim.

Background: Iron deficiency (ID) is the most common nutritional disorder affecting all age groups. Infants and young children are vulnerable to anemia especially iron deficiency anemia (IDA), which represents a public health problem with defined impacts on the health of communities. IDA, however, is a preventable and treatable condition; therefore, early diagnosis represents the cornerstone in protection from its adverse consequences and combating its contributing factors. Several international guidelines for the management of ID/IDA are available, however national guidelines that can be implemented and suits our local needs are lacking. Objective: To adapt the pre-existing high-quality practice guidelines for the screening, prevention and management of ID/IDA in different pediatric age groups, to be available for the national use by general practitioners, pediatricians, and other health care professionals. Results: The adaptation group for this guideline included key leaders from different Egyptian institutions. The panel used the ADAPTE methodology for adaptation of guidelines. The panel prioritized the health questions and recommendations according to their importance for clinicians and patients. The procedure included searching for existing guidelines, quality appraisal, and adaptation of the recommendations to the target context of use. The guideline covered all important aspects of detection, identification of infants, children, and adolescents at high risk of developing ID/IDA, proper management, and prevention. The final version of the adapted clinical practice guideline has been made after thorough review of an external review panel and was guided by their official recommendations and modifications. Implementation tools included algorithms, tables, and flow charts to aid decision making in practice, as well as patient-directed information in the Arabic language. Conclusions: This adapted guideline serves as a tool for the screening, prevention and management of ID/IDA in different pediatric age groups. [ABSTRACT FROM AUTHOR]

The aim of this study was to evaluate the risks of self-feeding, transition to early solid food and family meals, choking risk, anemia risk and obesity risk in 6–12-month-old infants who were introduced to complementary feeding using the traditional complementary feeding (TCF) and baby-led weaning (BLW) methods/training. Mothers of infants who had not yet transitioned to complementary feeding were included in this randomized study. The mothers of 62 infants included in the study were randomized into the intervention groups as TCF and BLW, classified according to the number of children and education level. The research was carried out according to the CONSORT-2010 guidelines after randomization and was concluded with 52 infants and their mothers. It was found in the study that self-feeding and transition to solid foods in infants fed with the BLW method was higher than the infants fed with the TCF method (p < 0.05). A significant increase was observed in the hemoglobin level of infants fed with the BLW method over time (p < 0.001). It was concluded that the BLW method did not lead to risks of obesity, anemia and iron deficiency in transition to complementary feeding. Secondary results indicated that feeding with the BLW method promoted self-feeding and early transition to solid foods and did not lead to the risk of choking. Complementary feeding with the BLW method can be safely used by both mothers, healthcare professionals and researchers. Trial Registration: register.clinicaltrials.gov ; Identifier: NCT05771324 • Training given for the TCF with the BLW method did not cause anemia risk. • BLW method revealed an early transition to solid food in infants. • BLW feeding is a safe and evidence-based nutritional approach.

Objective. To describe the iron status profile and to propose hemoglobin adjustment factors for altitude for children aged 6 to 8 months in Lima, Arequipa, Cusco and Puno. Materials and methods. Cross-sectional study in children aged 6 to 8 months from four cities. We measured hemoglobin and other iron biomarkers, C-reactive protein (CRP), among others. To estimate the adjustment equation, we applied an exponential regression. We excluded children with iron deficiency (ID) and/or inflammation. Results. The proportions of ID were higher in Puno and Arequipa, while inflammation did not exceed 19% in any of the cities. Hemoglobin showed an exponential increase at higher altitude. The adjustment equation was: 10.34249 x (1.00007 ^ Alt). Conclusions. Children residing in Arequipa and Puno showed higher rates of ID and lower iron reserves; furthermore, the increase in hemoglobin by altitude was exponential, showing the need to adjust hemoglobin at altitude.

Some, but not all, intravenous iron formulations have been recognized to induce renal phosphate wasting syndrome. Most commonly this has been reported following treatment of iron deficiency anemia (IDA) with ferric carboxymaltose (FCM). A search of PubMed identified relevant randomized controlled trials (RCTs), and case studies evaluating hypophosphatemia (HPP) resulting from intravenous iron treatment. While more recent larger comparative RCTs have confirmed that the majority of patients receiving FCM, especially those with normal renal function, may experience severe HPP, complete documentation is hampered by inconsistent reporting of serum phosphate in such trials. Similarly, while case series and RCTs have documented the persistence of HPP for several weeks or even months, the lack of studies lasting beyond 5-6 weeks has constrained full understanding of the duration of effect. Clinical trials have established that the mechanism involves the bone/metabolic axis with the elevation of intact fibroblast growth factor 23 playing the central role. Reports continue to accumulate of the clinical consequences of severe HPP which are, most commonly, bone abnormalities following repetitive dosing. Case reports and studies, however, have also shown that symptomatic hypophosphatemia can occur after a single FCM dose. The frequency of such events remains unknown, in part due to lack of awareness of hypophosphatemia coupled with the fact that the most common acute symptoms of HPP (fatigue and weakness) are the same for IDA and for many of the chronic diseases that cause IDA. Changes to US and European prescribing information for FCM should raise awareness of the potential for HPP and need to monitor patients at risk for it.

Iron deficiency is a common cause of morbidity and can arise as a consequence or complication from many diseases. The use of intravenous iron has increased significantly in the last decade, but concerns remain about indications and administration. Modern intravenous iron preparations can facilitate rapid iron repletion in one or two doses, both for absolute iron deficiency and, in the presence of inflammation, functional iron deficiency, where oral iron therapy is ineffective or has not worked. A multidisciplinary team of experts experienced in iron deficiency undertook a consensus review to support healthcare professionals with practical advice on managing iron deficiency in gastrointestinal, renal and cardiac disease, as well as; pregnancy, heavy menstrual bleeding, and surgery. We explain how intravenous iron may work where oral iron has not. We provide context on how and when intravenous iron should be administered, and informed opinion on potential benefits balanced with potential side-effects. We propose how intravenous iron side-effects can be anticipated in terms of what they may be and when they may occur. The aim of this consensus is to provide a practical basis for educating and preparing staff and patients on when and how iron infusions can be administered safely and efficiently. Key messages Iron deficiency treatment selection is driven by several factors, including the presence of inflammation, the time available for iron replenishment, and the anticipated risk of side-effects or intolerance. Intravenous iron preparations are indicated for the treatment of iron deficiency when oral preparations are ineffective or cannot be used, and therefore have applicability in a wide range of clinical contexts, including chronic inflammatory conditions, perioperative settings, and disorders associated with chronic blood loss. Adverse events occurring with intravenous iron can be anticipated according to when they typically occur, which provides a basis for educating and preparing staff and patients on how iron infusions can be administered safely and efficiently.

BackgroundBoth iron deficiency and overload may adversely affect neurodevelopment.ObjectivesThe study assessed how changes in early-life iron status affect iron homeostasis and cytoarchitecture of hippocampal neurons in a piglet model.MethodsOn postnatal day (PD) 1, 30 Hampshire × Yorkshire crossbreed piglets (n = 15/sex) were stratified by sex and litter and randomly assigned to experimental groups receiving low (L-Fe), adequate (A-Fe), or high (H-Fe) levels of iron supplement during the pre- (PD1-21) and postweaning periods (PD22-35). Pigs in the L-Fe, A-Fe, and H-Fe groups orally received 0, 1, and 30 mg Fe · kg weight-1 · d-1 preweaning and were fed a diet containing 30, 125, and 1000 mg Fe/kg postweaning, respectively. Heme indexes were analyzed weekly, and gene and protein expressions of iron regulatory proteins in duodenal mucosa, liver, and hippocampus were analyzed through qRT-PCR and western blot, respectively, on PD35. Hippocampal neurons stained using the Golgi-Cox method were traced and their dendritic arbors reconstructed in 3-D using Neurolucida. Dendritic complexity was quantified using Sholl and branch order analyses.ResultsPigs in the L-Fe group developed iron deficiency anemia (hemoglobin = 8.2 g/dL, hematocrit = 20.1%) on PD35 and became stunted during week 5 with lower final body weight than H-Fe group pigs (6.6 compared with 9.6 kg, P

Background Anemia affects 40% of pregnant women globally, leading to maternal mortality, premature birth, low birth weight, and poor baby development. Iron deficiency causes over 40% of anemia cases in Africa. Oral iron supplementation is insufficient for Low-and-Middle-Income-Countries (LMICs) to meet current WHO targets. We hypothesized that a single intravenous dose of Ferric Carboxymaltose (FCM) may be more effective than oral iron treatment for anemia recovery, particularly in these settings where women present late for antenatal care. Methods This is a two-arm parallel open-label individual-randomized controlled trial in third trimester, in malaria Rapid Diagnostic Test-negative pregnant women with moderate or severe anemia - capillary hemoglobin

BACKGROUND: Serum markers currently used as indicators of iron status have clinical limitations. Hepcidin, a key regulator of iron homeostasis, is reduced in iron deficiency (ID) and increased in iron overload. We describe the first CLIA-validated immunoassay with excellent accuracy and precision to quantify human serum hepcidin. Its diagnostic utility for detecting ID in first-time blood donors was demonstrated. METHODS: A monoclonal competitive ELISA (C-ELISA) was developed for the quantitation of human hepcidin and validated according to CLIA guidelines. Sera from nonanemic first-time blood donors (n = 292) were analyzed for hepcidin, ferritin, transferrin, and serum iron. Logistic regression served to determine the utility of hepcidin as a predictor of ID. RESULTS: The C-ELISA was specific for human hepcidin and had a low limit of quantitation (4.0 ng/mL). The hepcidin concentration measured with the monoclonal C-ELISA was strongly correlated with a previously established, extensively tested polyclonal C-ELISA (Blood 2008;112:4292-7) (r = 0.95, P 0.9. For predicting ID defined by ferritin

BackgroundFew cross-sectional studies report iron deficiency (ID) prevalence in women of different race/ethnicity and ages in US or Canada.Materials and methodsWe evaluated screening observations on women who participated between 2001-2003 in a cross-sectional, primary care-based sample of adults ages ≥25 y whose observations were complete: race/ethnicity; age; transferrin saturation; serum ferritin; and HFE p.C282Y and p.H63D alleles. We defined ID using a stringent criterion: combined transferrin saturation

Introduction: Anemia is a condition in which there is a low concentration of hemoglobin (Hb) levels. Although many causes of anemia have been identied, there are few studies in which they are related to epidemiological factors in the rst months of life. Objective: To determine the factors associated with hemoglobin levels in children under 6 months of age hospitalized in a specialized pediatric center in Peru. Methods: Cross-sectional study in children under 6 months of age hospitalized in the medical services of a pediatric center during the year 2017, 267 medical records were reviewed, emphasizing clinical and epidemiological characteristics. Results: 61.4% of the infants were female, and only 6.7% of the proportion of the population studied were less than 1 month old. 6.7% had low birth weight, and 53.2% had a normal delivery. The level of anemia in hospitalized children under 6 months of age is 66.7%. Conclusions:According to the bivariate analysis, a signicant association was found between hemoglobin levels with the variables age, nutritional status of weight for length and hospital causes. Regarding the multivariate analysis, only an association was found between age and the median Hb present in boys and girls aged 0 to 5 months hospitalized in a pediatric center in Peru.

Iron is an essential cofactor needed for normal functions of various enzymes and its depletion lead to increase DNA damage, genomic instability, deteriorate innate, adaptive immunity, and promote tumor development. It is also linked to tumorigenesis of breast cancer cells through enhancing mammary tumor growth and metastasis. There is insufficient data describing this association in Saudi Arabia. This study aims to determine the prevalence of iron deficiency and its association with breast cancer among premenopausal and postmenopausal women referred for breast cancer screening center in Al Ahsa, Eastern Province of Saudi Arabia. Age, hemoglobin level, iron level, history of anemia, or iron deficiency were collected from patients' medical records. The included participants were grouped based on their age into premenopausal (<50 years) or postmenopausal (⩾50 years). The definition of low Hb implemented (Hb below 12 g/dL) and low total serum Iron levels (below 8 μmol/L). Logistic regression test was used to compute the association between having a positive cancer screening test (radiological or histocytological) and participant's lab results. The results are presented as odds ratios and 95% confidence intervals. Thrree hundred fifty-seven women were included, 77% (n = 274) of them were premenopausal. This group cases had more history of iron deficiency (149 [60%] vs 25 (30%), P =.001) compared to those in the postmenopausal group. The risk of having a positive radiological cancer screening test was associated with age (OR = 1.04, 95% CI 1.02-1.06), but negatively was associated with iron level (OR = 0.9, 95% CI 0.86-0.97) among the entire cohort. This study is the first to propose an association between iron deficiency and breast cancer among Saudi young females. This could suggest iron level as a new risk factor that may be used by clinicians to assess breast cancer risk. [ABSTRACT FROM AUTHOR]

Aim: This study aimed to assess the status of iron stores and the frequency of iron deficiency anemia in Celiac disease (CD) patients referred to the Golestan Research Center of Gastroenterology and Hepatology, Gorgan, Iran. Background: Studies have shown that nutritional deficiencies affect 20-38% of patients with CD due to malabsorption and as a result of a gluten-free diet. Methods: In this study, 59 out of 100 CD patients were assessed. The presence and severity of anemia were determined using the concentration of serum hemoglobin according to WHO criteria. The status of body iron stores was also assessed based on serum ferritin levels. Results: Mean and SD of age, duration of disease, serum hemoglobin, ferritin, TIBC, and serum iron were 39.9±11.9 years, 69.8±45.4 months, 12.6±1.99 g/dl, 54.3±55.3 mg/dL, 365.9±49.1 μg/dL, and 84.1±37.1 μg/dL, respectively. 68.42% had no anemia, 19.3% had mild anemia, 8.77% had moderate anemia, and 3.51% had severe anemia. 25.42% of patients had depleted iron stores, 71.19% had normal iron stores, and 3.39% were exposed to iron overload. There was a statistically significant correlation between serum hemoglobin and the duration of disease diagnosis (P=0.037, r=0.302). Conclusion: In this study, 31.58% of CD patients on a gluten-free diet had some degree of anemia. In addition, 25.42% of patients had depleted iron stores. These results suggest that CD patients should be evaluated for iron status, even with a gluten-free diet. [ABSTRACT FROM AUTHOR]

As the most common nutritional disorder, iron deficiency represents a major public health problem with broad impacts on physical and mental development. However, treatment is often compromised by low iron bioavailability and undesired side effects. Here, we report on the development of active mineral delivery vehicles using Mg-based micromotors, which can autonomously propel in gastrointestinal fluids, aiding in the dynamic delivery of minerals. Iron and selenium are combined as a model mineral payload in the micromotor platform. We demonstrate the ability of our mineral-loaded micromotors to replenish iron and selenium stores in an anemic mouse model after 30 days of treatment, normalizing hematological parameters such as red blood count, hemoglobin, and hematocrit. Additionally, the micromotor platform exhibits no toxicity after the treatment regimen. This proof-of-concept study indicates that micromotor-based active delivery of mineral supplements represents an attractive approach toward alleviating nutritional deficiencies.

ObjectiveTo examine the impacts of a Solar Market Garden 1-year solar-powered drip irrigation (SMG) programme in Kalalé district of northern Benin on mothers' nutritional status and micronutrient levels.DesignUsing a quasi-experimental design, sixteen villages were assigned to four groups: (i) SMG women's groups (WG); (ii) comparison WG; (iii) SMG non-WG (NWG); and (iv) comparison NWG. Difference-in-differences (DID) estimates were used to assess impacts on mothers' food consumption, diversity, BMI, prevalence of underweight (BMI < 18·5 kg/m2) and anaemia, and deficiencies of iron (ID) and vitamin A (VAD).SettingKalalé district, northern Benin.ParticipantsNon-pregnant mothers aged 15-49 years (n 1737).ResultsThe SMG programme significantly increased mothers' intake of vegetables (DID = 25·31 percentage points (pp); P < 0·01), dietary diversity (DID = 0·74; P < 0·01) and marginally increased their intake of flesh foods (DID = 10·14 pp; P < 0·1). Mean BMI was significantly increased among SMG WG compared with the other three groups (DID = 0·44 kg/m2; P < 0·05). The SMG programme also significantly decreased the prevalence of anaemia (DID = 12·86 pp; P < 0·01) but no impacts were found for the prevalence of underweight, ID and VAD.ConclusionsImproving mothers' dietary intake and anaemia prevalence supports the need to integrate gender-based agriculture to improve nutritional status. However, it may take more than a year, and additional nutrition and health programmes, to impact the prevalence of maternal underweight, ID and VAD.
