A-159 Re-evaluating Ferritin Cutoffs for the Diagnosis of Iron Deficiency and Iron Deficiency Anemia

Abstract Background Iron deficiency (ID) is the most common nutrient deficiency in the world and iron deficiency anemia (IDA) is estimated to affect 1.24 billion people. Serum ferritin is an iron storage protein commonly used as a biomarker for ID and IDA. The ferritin lower limit of normal (LLN) defined in many clinical laboratories is lower than evidence-based cutoffs and may not detect ID and IDA with adequate sensitivity, particularly when sex-based reference intervals (RIs) are used. This may be due in part to the use of asymptomatic, iron-depleted individuals for RI studies. Recent efforts have been made to increase the LLN for ferritin to at least 30 ng/mL and re-evaluate sex based RIs to improve diagnosis of ID and IDA. In this study, we aimed to investigate LLN ferritin cutoffs for ID and IDA in our patient population. Methods Patient data from June 2022-May 2023 were collected with approval from the Institutional Review Board (IRB), including age, sex, and values for ferritin, iron, transferrin saturation, and hemoglobin. Patients were classified as iron replete (IR), ID, or IDA based on measurements for iron, transferrin saturation, and hemoglobin. IR patients were defined as having iron and transferrin saturation values within current RIs, while those below the cutoff were grouped as ID. ID and IDA were further classified based on hemoglobin values. A range of ferritin concentrations between 1 and 100 ng/mL were used to calculate true and false positive rates (TPR and FPR) and diagnostic accuracy (DA). Receiver operator characteristic (ROC) curve and J index analysis were used to define optimal ferritin cutoffs for ID and IDA. Results Data from 26,455 patients (65% female) were used in this study. Conclusions These findings highlight the need to re-examine ferritin RIs in the context of ID/IDA, especially for those patients assigned female at birth.

Assessment of Risk Factors for Women with Iron Deficiency Anemia During Pregnancy

Background: Globally, iron insufficiency is the most common nutrient deficiency and the primary cause of anemia. Iron deficiency can result in maternal anemia and decreased infant iron reserves due to increased iron demand during pregnancy. Objective: The study was designed to assess the risk factors encountered during pregnancy among pregnant women with iron deficiency anemia. Materials and Methods: The study was conducted on one hundred pregnant women enrolled on the health care centers who were diagnosed as anemic. The data were obtained from all through direct interviews using a special questionnaire covering the sociodemographic characteristics, diet habits, and supplements taken during pregnancy. The one-way ANOVA test analysis was done to see the association of each variable with the anemia severity. The probability value <0.05 was considered statistically significant. Results: The results indicated that there was no statistically significant relation between iron deficiency anemia and all the socio-demographic characteristics which included; age, parity, educational level, occupation, family size, and gestational age. While there is a highly statistically significant relation between iron deficiency anemia and diet habit of pregnant women regarding the frequency of intake of meats, fishes, vegetables, and fruits at p-value = 0.001, intake pulse at p-value = 0.012, intake of nuts at p-value = 0.021, and drinking tea at p-value = 0.001. Conclusion: Educating pregnant women to eat iron-rich foods may be useful as a strategy for reducing iron deficiency anemia during pregnancy, also using of iron supplements, folic acid and vitamin B12 is regarded as a successful way to treat anemia.

Early life stress and iron metabolism in developmental psychoneuroimmunology

An estimated 250 million children face adverse health outcomes from early life exposure to severe or chronic social, economic, and nutritional adversity, highlighting/emphasizing the pressing concern about the link between ELS and long-term implications on mental and physical health. There is significant overlap between populations experiencing high levels of chronic stress and those experiencing iron deficiency, spotlighting the potential role of iron as a key mediator in this association. Iron, an essential micronutrient for brain development and immune function, is often depleted in stress conditions. Iron deficiency among the most common nutrient deficiencies in the world. Fetal and infant iron status may thus serve as a crucial intermediary between early chronic psychological stress and subsequent immune system changes to impact neurodevelopment. The review presents a hypothesized pathway between early life stress (ELS), iron deficiency, and neurodevelopment through the hypothalamic-pituitary-adrenocortical (HPA) axis and the IL-6-hepcidin axis. This hypothesis is derived from (1) evidence that stress impacts iron status (2) long-term neurodevelopmental outcomes that are shared by ELS and iron deficiency exposure, and (3) possible mechanisms for how iron may mediate the relation between ELS and iron deficiency through alterations in the developing immune system. The article concludes by proposing future research directions, emphasizing the need for rigorous studies to elucidate how stress and iron metabolism interact to modify the developing immune system. Understanding these mechanisms could open new avenues for improving human health and neurodevelopment for women and children globally, making it a timely and vital area of study in psychoneuroimmunology research.

A69 EXPANDED ROLE OF THE DIETITIAN IN THE CLINICAL MANAGEMENT OF PATIENTS WITH CELIAC DISEASE

Abstract Background The only available treatment for Celiac Disease (CeD) is adhering to a strict gluten-free diet (GFD). However, a GFD has been associated with multiple nutrient imbalance and deficiencies, which are often under-recognized and remain untreated. Aims To identify the reasons for referral to a registered dietitian (RD) and RD-recommended dietary interventions for patients with CeD attending a specialised Adult Celiac Disease Clinic. Methods We conducted a retrospective chart review using nutrition assessment forms completed by the RD between November 2021 and May 2022. CeD diagnosis was performed through specific serology (anti-tissue transglutaminase IgA and anti-deamidated gliadin peptide IgG) and confirmed by duodenal biopsies demonstrating villous atrophy. We collected data on demographics, diagnosis date, nutritional status (BMI), micronutrients measured in serum, gastrointestinal (GI) symptoms, reason for consult, and the recommendations made by the RD. Data was collected in RedCap (v. 11.1, 2021, US) and expressed as both a proportion and Median (IQR). Results A total of 136 visits from 102 patients were included in the analysis. Of them, 77 were female (75.5%) with a mean age of 40.3 yrs (+/- 16.0). The median year of CeD diagnosis was 4 (IQR= 6) from 2002-2022. Patients reported various symptoms including bloating (50.9%), abdominal pain (34.3%), and constipation (23.5%). 56% of patients were overweight or obese (BMI ampersand:003E25), and 4.9% were undernourished (BMIampersand:003C18). The most common nutrient deficiencies were ferritin below 30 ng/mL (58.8%), zinc below 9.4 µmol/L (23.5%), and suboptimal levels of vitamin D (38.2%). The most common reasons for referral to the RD were to assess GFD adherence (44.1%), dietary management of GI symptoms (30.4%) and nutritional optimization (24.5%). We identified 18 different interventions recommended by the RD, the most common being how to prevent gluten cross-contamination (58.8%), tips for dining out (43.1%), GF diet education (32.4%), and increasing fibre intake (30.4%). The most common reasons for follow up visits (n=34) included dietary management of GI symptoms (60.9%) and GFD adherence (43.5%). Conclusions Patients with CeD face multiple nutritional challenges associated with following a GFD, and a number of GI symptoms. Although the GFD is the only available treatment, this review identifies the need for multiple individualized dietary interventions, which require and encourage the inclusion of a specialized RD to ensure personalized, effective care and support in the management of CeD.

Characterization of Physiology, Photosynthesis, and Nutrition Based on Induced Deficiencies of Macro- and Micronutrients in Basil (Ocimum basilicum L.)

Basil (Ocimum basilicum L.) contains abundant nutrients and is considered an economically important edible vegetable. The optimal nutrient levels will increase the productivity and basil quality. However, prominent research on basil regarding the diagnostic nutrient deficiency standard and the corresponding nutrient uptake is still scarce. To this end, the basil plants were hydroponically cultured and subjected to one of 14 nutrient solution treatments, corresponding to the omission of a single nutrient element (designated as -N, -P, -K, -Ca, -Mg, -NH4+, -NO3−, -S, -Fe, -Mn, -B, -Zn, -Mo, and -Cu) and a complete nutrient solution (CS) as the control. The most common nutrient deficiency symptoms were chlorosis, stunted roots and growth, and even leaf necrosis and abscission, in particular of -N, -P, -NO3−, and -Fe. We also found that basil is a NH4+-sensitive species. The photosynthetic capacity (photosynthesis pigments, Fv/Fm ratio, and greenness index) was disturbed to varying degrees when a single nutrient was omitted from the nutrient solution. Additionally, the omission of a specific single nutrient confers significant differences in the tissue nutrients, regardless of the macronutrients and micronutrients considered. Concomitantly, multivariate analysis suggested the correlations among certain important nutrients were distinctly different under different treatments (correlation analysis); the influences of different nutrient deficiencies on the tissue nutrient concentrations showed similarity (principal component analysis). Collectively, the growth, physiological, and biochemical changes studied in this trial not only improved our knowledge for diagnosing nutrient deficiency symptoms for practical cultivation but also provided a comprehensive understanding of the internal nutrient associations in basil.

Iron Deficiency among a Group Syrian Women: Causes and Treatment

Iron deficiency is one of the most common nutrient deficiencies in the world. The aim of our research was to identify the most common causes of iron deficiency anemia and the associated factors of lifestyle, dietary habits and menstrual cycle.

Iron Deficiency Anemia in Infancy, Childhood, and Adolescence.

Iron deficiency is the most common nutrient deficiency in the world. Epidemiological data indi- cate that iron deficiency is more prevalent in infants, in preschool-children, and in adolescents. Etiologies of iron deficiency in children include inadequate dietary iron intake, which is the most common cause, as well as increased iron requirements, bleeding, and intestinal iron absorption disorders. Iron deficiency can lead to symptoms related to anemia, may interfere with neuro- development and may cause skin, hair, nail, and gastrointestinal problems. This review focuses on the causes, signs, symptoms, diagnosis and management of iron deficiency in infancy, child- hood, and adolescence.

Early-life iron deficiency persistently disrupts affective behaviour in mice

Background/Objective Iron deficiency (ID) is the most common nutrient deficiency, affecting two billion people worldwide, including about 30% of pregnant women. During gestation, the brain is particularly vulnerable to environmental insults, which can irrevocably impair critical developmental processes. Consequently, detrimental consequences of early-life ID for offspring brain structure and function have been described. Although early life ID has been associated with an increased long-term risk for several neuropsychiatric disorders, the effect on depressive disorders has remained unresolved. Materials and methods A mouse model of moderate foetal and neonatal ID was established by keeping pregnant dams on an iron-deficient diet throughout gestation until postnatal day 10. The ensuing significant decrease of iron content in the offspring brain, as well as the impact on maternal behaviour and offspring vocalization was determined in the first postnatal week. The consequences of early-life ID for depression- and anxiety-like behaviour in adulthood were revealed employing dedicated behavioural assays. miRNA sequencing of hippocampal tissue of offspring revealed specific miRNAs signatures accompanying the behavioural deficits of foetal and neonatal ID in the adult brain. Results Mothers receiving iron-deficient food during pregnancy and lactation exhibited significantly less licking and grooming behaviour, while active pup retrieval and pup ultrasonic vocalizations were unaltered. Adult offspring with a history of foetal and neonatal ID showed an increase in depression- and anxiety-like behaviour, paralleled by a deranged miRNA expression profile in the hippocampus, specifically levels of miR200a and miR200b. Conclusion ID during the foetal and neonatal periods has life-long consequences for affective behaviour in mice and leaves a specific and persistent mark on the expression of miRNAs in the brain. Foetal and neonatal ID needs to be further considered as risk factor for the development of depression and anxiety disorders later in life. Key Messages Marginal reduction of gestational alimentary iron intake decreases brain iron content of the juvenile offspring. Early-life ID is associated with increased depression- and anxiety-like behaviour in adulthood. Reduction of maternal alimentary iron intake during pregnancy is reflected in an alteration of miRNA signatures in the adult offspring brain.

Nutritional Status and Its Detection in Patients with Inflammatory Bowel Diseases.

Malnutrition is an important issue in patients with inflammatory bowel diseases (IBDs) including Crohn's disease (CD) and ulcerative colitis (UC). It is caused by altered digestion and absorption within the small bowel, inadequate food intake, and drug-nutrient interactions in patients. Malnutrition is an essential problem because it is related to an increased risk of infections and poor prognosis in patients. It is known that malnutrition is also related to an increased risk of postsurgery complications in IBD patients. Basic nutritional screening involves anthropometric parameters with body mass index (BMI) and others (fat mass, waist-to-hip ratio, muscle strength), medical history concerning weight loss, and biochemical parameters (including the Prognostic Nutritional Index). Besides standard nutritional screening tools, including the Subjective Global Assessment (SGA), Nutritional Risk Score 2002 (NRS 2002), and Malnutrition Universal Screening Tool (MUST), specific nutritional screening tools are used in IBD patients, such as the Saskatchewan Inflammatory Bowel Disease-Nutrition Risk Tool (SaskIBD-NR Tool and IBD-specific Nutritional Screening Tool). There is a higher risk of nutrient deficiencies (including iron, zinc, magnesium) and vitamin deficiencies (including folic acid, vitamin B12 and D) in IBD patients. Therefore, regular evaluation of nutritional status is important in IBD patients because many of them are undernourished. An association between plasma ghrelin and leptin and nutritional status in IBD patients has been observed. According to some authors, anti-tumor necrosis factor (anti-TNFα) therapy (infliximab) can improve nutritional status in IBD patients. On the other hand, improvement in nutritional status may increase the response rate to infliximab therapy in CD patients. Optimization of nutritional parameters is necessary to improve results of conservative and surgical treatment and to prevent postoperative complications in patients with IBDs. This review presents basic nutritional screening tools, anthropometric and laboratory parameters, dietary risk factors for IBDs, common nutrient deficiencies, associations between anti-TNFα therapy and nutritional status, selected features regarding the influence of nutritional status, and surgical outcome in IBD patients.

Analysis of hot trends in research on the association between vitamin D and cardiovascular disease.

Vitamin D deficiency is the most common nutrient deficiency. Numerous studies suggest that vitamin D is an independent risk factor for cardiovascular disease. The objective is to visualize the research hotspots and evolution trends of the correlation between vitamin D and cardiovascular disease by using multivariate statistics and social network analysis techniques and to compare adult research with that of children in this field. (Vitamin D [MeSH Major Topic]) AND (cardiovascular disease [MeSH Major Topic]) were retrieved from the PubMed database by time period. The bibliographic items co-occurrence matrix builder (BICOMB) was adopted to extract high-frequency subject terms and establish the core subject term co-occurrence matrix. With the Netdraw function of Ucinet 6.0 software, the social network of core subject terms was completed. Before 2010, there was a slow increase in the number of research papers covering all age groups in this field (157, 54, 84, and 211 papers were published in stages 1-4, respectively). From 2010 to 2020, there were 1,423 papers retrieved, showing a significantly increased research heat. The overall development trend of the research on the association between vitamin D and cardiovascular disease in children is similar to that in all age groups. From 2010 to 2020, 122 related papers were published (while before 2009, there were only 43 papers in all), presenting a good overall development trend. The social network analysis of core subject terms showed gradually increased correlations between research hotspots, from the early studies limited on the physiological function of vitamin D in cardiovascular diseases, to the role of vitamin D in the comorbidities of various cardiovascular diseases and its value as an intervention measure. Researches on the association between vitamin D and cardiovascular disease has a good overall development trend. Study of the mechanisms and the role of vitamin D in the common co-morbidities of cardiovascular disease and its therapeutic value will be the focus of future research.

Iron Deficiency Among a Group Syrian Woman: Causes and Treatment

Iron deficiency is one of the most common nutrient deficiencies in the world. The aim of our research was to identify the most common causes of iron deficiency anemia and the associated factors of lifestyle, dietary habits and menstrual cycle. We selected a random sample of women attending the gynecology department at Tishreen University Hospital, and obtained the results of a complete blood count (HCT and HB) CBC for 100 participating women from April 2022 until the end of June 2022. As a result, 67% of women nearly two-thirds were anemic which is considered high for a sample randomly taken from the gynecological clinic in Tishreen university hospital.

Malnutrition of pregnant beef cows and the impact on passive immunity transfer to calves

Nutritional management in rangeland beef cattle systems prioritises optimal body condition scores at calving for improved fertility and reproductive success. However, this focus often overlooks short-term dietary deficiencies before calving, which can lead to adverse outcomes for neonatal calves. This review explores the effects of beef cow malnutrition during the periparturient period on colostrum production, lactation onset, and passive immunity transfer to calves. Additionally, it discusses the long-term impact of such malnutrition on the offspring. By understanding how nutritional interventions affect the transition from gestation to lactation, it becomes possible to enhance calf health and survival in arid tropical environments. Commonly occurring short-term dietary restrictions, particularly protein deficiencies, can disrupt the hormonal equilibrium, resulting in reduced colostrum volume and quality, hindering calf growth and increasing mortality risks. Furthermore, dietary restrictions during this period affect critical physiological processes such as mammary gland blood flow and fetal small-intestine development. The review explores how these constraints influence colostrum production and immunoglobulin absorption by neonatal calves. Additionally, it highlights the significance of addressing other common nutrient deficiencies such as phosphorus and water and investigates the potential benefits of supplementing microbial products to enhance rumen function and protect cows from inflammation. Ultimately, addressing malnutrition during pregnancy is essential to prevent negative impacts on offspring performance, including alterations in carcass composition and muscle marbling. Consequently, cattle producers who aim for superior muscle marbling in the carcass by using costly genetics should give priority to enhancing nutritional programs for late-pregnant cows. In conclusion, a comprehensive understanding of the effects of malnutrition during the periparturient period on colostrum production, passive immunity transfer, and overall calf health is crucial for developing effective nutritional interventions that improve colostrum production, passive immunity transfer, and overall calf health in rangeland beef cattle systems.

Prevalence and Etiological Profile of Anemia in Hospitalized Geriatric Patients

Abstract Background: Anemia is a common health problem in the elderly and is associated with a wide range of adverse outcomes. The prevalence of anemia at older age is increasing as a result of improved diagnostics and demographic changes in our societies. The aim was to determine the prevalence of anemia in a cohort of hospitalized geriatric population and the possible underlying etiology. Subjects and Methods: This was a cross-sectional study among patients aged more than 60 years hospitalized in medical wards. Anemia was defined based on the World Health Organization criteria: Hb <12.0 g/dL in women and Hb <13.0 g/dL in men. Results: Anemia was observed in 214 patients (73.3%). The average age of the study participants was 68.16 ± 1.32 years. The mean hemoglobin level was 8.48 ± 2.26 g/dl. About 51% had moderate anemia and 34% had severe anemia. Morphologically, microcytic anemia was the most common type (49.5%). Overall, nutritional causes of anemia exceeded nonnutritional causes (49%, n = 105 vs. 42.5%, n = 91). Iron deficiency anemia was the most common nutrient deficiency anemia seen in 49 participants (22.9%), followed by Vitamin B12 in 34 (15.9%) and folate in 10 (4.7%). Anemia of inflammation was diagnosed in 69 (32.2%) and hematological disorders in 6.1%. Common chronic diseases causing anemia were infection/autoimmune disorders in 35 (16.3%), chronic renal failure in 20 (9.3%), and solid-organ malignancies in 14 (6.5%). The etiology was multifactorial in 19 patients (8.9%) and unexplained in 8 (3.7%). Conclusions: Anemia was frequently diagnosed in this series of elderly hospitalized patients with a high burden of moderate-to-severe anemia. Most of them had an underlying treatable etiology. Potentially correctable nutritional deficiencies, such as iron, Vitamin B12, or folate deficiency, were identified as the most common causes. Unexplained anemia appears to be rare in hospitalized older patients.

The role of oral iron in the treatment of adults with iron deficiency.

Iron deficiency is the most common nutrient deficiency in the world, affecting over 20% of premenopausal women worldwide. Oral iron supplementation is often the first-line treatment for the acute and chronic management of iron deficiency due to its ease and accessibility. However, there is no consensus on the optimal formulation or dosing strategy, or which patients should be preferentially treated with intravenous iron. Management of iron deficiency is complicated by the hepcidin-ferroportin iron regulatory pathway, which has evolved to prevent iron overload and thereby creates an inherent limit on gastrointestinal iron uptake and efficacy of oral iron. Unabsorbed iron propagates many of the side effects that complicate oral iron use including dyspepsia and constipation, all of which can thus be exacerbated by excessive oral iron doses. Daily low dose and every other day dosing protocols have attempted to bypass this physiologic bottleneck to allow for effective absorption and limit side effects; however, this approach has still resulted in low fractional iron absorption. In the following manuscript, we review the pathophysiology of iron absorption and current evidence for various preparations of oral iron. Lastly, we highlight opportunities for further study to advance the care of individuals affected by iron deficiency.

Organ-specific expression of genes involved in iron homeostasis in wheat mutant lines with increased grain iron and zinc content.

BackgroundIron deficiency is a well-known nutritional disorder, and the imbalance of trace-elements, specifically iron, is the most common nutrient deficiency of foods across the world, including in Kazakhstan. Wheat has significant nutritional relevance, especially in the provision of iron, however many bread wheat varieties have low iron despite the need for human nourishment. In this study, the expression profiles of wheat homologous genes related to iron homeostasis were investigated. The work resulted in the development of two new M5 mutant lines of spring bread wheat through gamma-irradiation (200 Gy) with higher grain iron and zinc content, lower phytic acid content, and enhanced iron bioavailability compared to the parent variety. Mutant lines were also characterized by higher means of yield associated traits such as grain number per main spike, grain weight per main spike, grain weight per plant, and thousand-grain weight.MethodsThe homologous genes of bread wheat from several groups were selected for gene expression studies exploring the tight control of iron uptake, translocation rate and accumulation in leaves and roots, and comprised the following: (1) S-adenosylmethionine synthase (SAMS), nicotianamine synthase (NAS1), nicotianamine aminotransferase (NAAT), deoxymugineic acid synthetase (DMAS), involved in the synthesis and release of phytosiderophores; (2) transcription factor basic helix-loop-helix (bHLH); (3) transporters of mugineic acid (TOM), involved in long-distance iron transport; (4) yellow stripe-like (YSlA), and the vacuolar transporter (VIT2), involved in intracellular iron transport and storage; and lastly (5) natural resistance-associated macrophage protein (NRAMP) and ferritin (Fer1A).ResultsThe wheat homologous genes TaSAMS, TaNAS1, and TaDMAS, were significantly up-regulated in the roots of both mutant lines by 2.1–4.7-fold compared to the parent variety. The combined over-expression of TaYSlA and TaVIT2 was also revealed in the roots of mutant lines by 1.3–2.7-fold. In one of the mutant lines, genes encoding intracellular iron transport and storage genes TaNRAMP and TaFer1A-D showed significant up-regulation in roots and leaves (by 1.4- and 3.5-fold, respectively). The highest expression was recorded in the transcription factor TabHLH, which was expressed 13.1- and 30.2-fold in the roots of mutant lines. Our research revealed that genotype-dependent and organ-specific gene expression profiles can provide new insights into iron uptake, translocation rate, storage, and regulation in wheat which aid the prioritization of gene targets for iron biofortification and bioavailability.

What Gastroenterologists Should Know about Carcinoid Syndrome

Carcinoid syndrome (CS) is the most common functional syndrome associated with neuroendocrine neoplasia (NEN), particularly in intestinal NEN with extensive liver metastases. Owing to the heterogenous symptomatic scenario present in CS, recognition of these patients may be challenging. In this review, we explore some key clinical factors used to identify patients affected by CS, with particular focus on differential diagnoses of diarrhea, which is the main symptom of CS. Moreover, we highlight the importance of nutritional screening as a clinical indication to prevent malnutrition and to manage the most common nutrient deficiencies present in these patients.

NUTRITIONAL STATUS ASSESSMENT OF ORPHANAGE CHILDREN IN RAWALPINDI

Objective: To evaluate the health and nutritional status of the orphanage, to find frequency of nutritional deficiencies by physical examination findings and to assess their dietary intake and contrast it with individual recommended daily allowances.
 Study Design: Cross sectional study.
 Place and Duration of Study: Four orphanages of Rawalpindi, from Jan to May 2020.
 Methodology: Study was conducted at four orphanages of Rawalpindi on 276 children and adolescents. Children and adolescents in age group of 5-18 years and if they are resident of institution for more than 60 months were included in the study, while children who were extremely sick and mentally retarded were excluded from the study. Data was collected through questionnaire including demographic information, anthropometric assessment, nutritional deficiencies on physical examination and 24 hours food recall. Data was analyzed on SPSS 24.
 Results: Results showed that 34 (17%) children and adolescents were underweight, 99 (49.5%) stunted, 21 (10.5%) showed thinness and 9 (4.5%) were overweight. Most common nutrient deficiency was protein calorie malnutrition, Iron deficiency and vitamin A and B 12 deficiency. Study population was consuming less protein, Iron and fats in diet as compared to recommended daily allowances.
 Conclusion: Institutionalized children and adolescents are at risk of developing malnutrition due to financial constraints and ignorance of caregivers, which can lead to ill health of children. Programs are required to be undertaken for nutritional development of the orphanage children.

The Importance of Iron To Support Optimum Cognitive Development

The fetal brain anatomy development starts during the last trimester of pregnancy and continue in early months of life. This critical process makes it vulnerable to insufficient nutrition, while brain growth continues into adulthood, micronutrient status can affect functioning beyond childhood. Iron is an important nutrient for the production and growth of cells in the immune and neural systems. Iron deficiency (ID) is the most common nutrient deficiency in the world, affecting about half of all pregnant women and their offspring. Iron deficiency anemia has long been believed to have an effect on the central nervous system. Iron deficiency in late trimester and in newborn leads to abnormal cognitive function and emotional control that may continue in adulthood.
 In summary, despite some evidence that iron supplementation enhances cognitive performance. Evidence of the role of iron in brain development and the effect of iron deficiency or iron supplementation on early development is uncertain.

Diet-Induced Non-anemic Iron Deficiency Attenuates Adaptive Thermogenesis via Defective Iron Metabolism of Adipose Tissue in C57BL/6 Mice

ObjectivesIron deficiency is one of the most common nutrient deficiencies worldwide. Adaptive thermogenesis plays a critical role for maintaining energy homeostasis. Currently, the role of dietary iron deficiency on adaptive thermogenesis is unknown. We hypothesized that dietary iron deficiency attenuates adaptive thermogenesis via dysfunctional iron metabolism in adipose tissue. MethodsC57BL/6 male mice were fed a diet containing either adequate-iron (Cont: 35ppm) or deficient-iron (ID: 3ppm) throughout for 14 weeks and the last 10 weeks were fed a high-fat diet to induce obesity. Systemic iron status was evaluated by measuring serum ferritin, hemoglobin (Hb), and hematocrit (HCt). The iron content of adipose tissue was determined by ICP-MS spectrometer. The protein and gene expressions related to iron-handling and thermogenesis were measured in adipose tissue by Western blot analysis and qPCR. To assess adaptive thermogenic function, mice were exposed to cold temperature acutely (3 hour) or administrated with β3-adrenoceptor agonist (CL) for 5 days. The core body temperature and thermogenesis were determined by a rectal thermometer and infrared camera, respectively. ResultsThe ID mice displayed a non-anemic iron deficiency with reduced serum ferritin (p < 0.01), increased weight gain (p < 0.05) and decreased insulin sensitivity (p < 0.05) compared to Cont. The iron content was significantly reduced in the inguinal (iWAT, p < 0.05) of the ID mice, which was linked with reduced thermogenic heat release upon acute cold treatment. In addition, ID mice markedly reduced the adipose tissue browning and thermogenic heat release upon CL stimulation compared with Cont. In terms of iron metabolism, CL-induced coordinated iron uptake for mitochondrial biogenesis in the iWAT was impaired in the ID mice, which was comparable to inflammation-mediated defective adipose tissue browning and thermogenesis. ConclusionsIron deficiency induced visceral obesity and compromised thermogenic function due to defective iron metabolism in C57BL6 mice.
