BACKGROUND: Ethiopia has made remarkable progress in reducing child mortality over the last two decades. However, the under-5 mortality rate in Ethiopia is still higher than the under-5 mortality rates of several low- and middle-income countries (LMIC). On the other hand, the patterns and causes of child mortality have not been well investigated in Ethiopia. The objective of this study was to investigate the mortality trend, causes of death, and risk factors among children under 5 in Ethiopia during 1990-2013...

INTRODUCTION: Neonatal hemochromatosis (NH) is a rare neonatal disorder that results in liver cirrhosis with hemosiderin deposition in the liver and other organs, similarly to hereditary hemochromatosis. Excess iron is transferred from the mother to fetus through the placenta in NH. We examined the expression of iron metabolism-related substances in placental syncytiotrophoblasts (STB) by immunostaining to clarify how the transfer of iron through STB increases in NH. METHODS: Immunostaining was performed using formalin-fixed, paraffin-embedded sections of placentae from three NH cases, four gestational age-matched controls, and, depending on the antibody examined, five to seven full-term controls...

Gestational alloimmune liver disease, previously known as neonatal hemochromatosis, is characterized by severe liver disease in neonatal period, associated with intra and extrahepatic iron accumulation. It is postulated an alloimmune origin, which has opened new opportunities in the treatment and prevention during risk pregnancies, changing the prognosis of this pathology. We report the case of a newborn that presents early liver failure, with clinical and analytical features compatible with gestational alloimmune liver disease...

OBJECTIVE: Prematurity, stillbirth and other adverse birth outcomes remain major concerns in resource-limited settings. Poor dietary intake of micronutrients during pregnancy has been associated with increased risk of adverse outcomes. We determined the relationships between dietary Fe and Ca intakes during pregnancy and risks of adverse birth outcomes among HIV-negative women. DESIGN: Women's diet was assessed through repeated 24 h diet recalls in pregnancy. Mean intakes of total Fe, Fe from animal sources and Ca during pregnancy were examined in relation to adverse birth outcomes and neonatal mortality...

BACKGROUND: Iron deficiency is a common childhood micronutrient deficiency that results in altered hippocampal function and cognitive disorders. However, little is known about the mechanisms through which neonatal iron deficiency results in long lasting alterations in hippocampal gene expression and function. DNA methylation is an epigenetic mark involved in gene regulation and altered by environmental factors. In this study, hippocampal DNA methylation and gene expression were assessed via reduced representation bisulfite sequencing and RNA-seq on samples from a previous study reporting reduced hippocampal-based learning and memory in a porcine biomedical model of neonatal iron deficiency...

Maternal and child health is an important issue throughout the world. Given their impact on maternal and child health, nutritional issues need to be carefully addressed. Accordingly, the effect of maternal, child, and nutritional disorders on disability-adjusted life years (DALYs) should be calculated. The present study used DALYs to estimate the burden of disease of maternal, neonatal, and nutritional disorders in the Korean population in 2012. For this purpose, we used claim data of the Korean National Health Insurance Service, DisMod II, and death data of the Statistics Korea and adhered to incidence-based DALY estimation methodology...

INTRODUCTION: Hemolytic kernicterus, an indirect bilirubin-induced brain dysfunction, is associated with hyper-bilirubinemia in mammalian neonates. In this study, a new model of kernicterus has been developed using intra-peritoneal injections of phenyl hydrazine and subcutaneous injections of sulfisoxazole. These drugs can potentially induce kernicterus in neonatal through changes in hemolysis and hypo-albumin. METHODS: For this purpose, 7-day-old male Wistar rats (n=72; mean weight 11±1g) were used...

Lipoic acid synthase (LIAS) is an iron-sulfur cluster mitochondrial enzyme which catalyzes the final step in the de novo pathway for the biosynthesis of lipoic acid, a potent antioxidant. Recently there has been significant interest in its role in metabolic diseases and its deficiency in LIAS expression has been linked to conditions such as diabetes, atherosclerosis and neonatal-onset epilepsy, suggesting a strong inverse correlation between LIAS reduction and disease status. In this study we use a bioinformatics approach to predict its structure, which would be helpful to understanding its role...

BACKGROUND: Prenatal conditions of enhanced oxidative stress (OS) linked to inflammation or hypoxia have been associated with impaired fetal growth and preterm delivery. Little is known regarding biomarkers of OS in the cord blood of preterm infants and placental histological patterns. OBJECTIVES: To test the hypothesis that placental lesions indicating chorioamnionitis (CA) or vascular underperfusion (VU) are associated with increased OS in the offspring. METHODS: 120 neonates born below 29(+6) weeks of gestational age (GA) were enrolled...

Prenatal supplementation with protein-energy (PE) and/or multiple-micronutrients (MMNs) may improve fetal growth, but trials of lipid-based nutritional supplements (LNSs) have reported inconsistent results. We conducted a post-hoc analysis of non-primary outcomes in a trial in Gambia, with the aim to test the associations of LNS with fetal growth and explore how efficacy varies depending on nutritional status. The sample comprised 620 pregnant women in an individually randomized, partially blinded trial with four arms: (a) iron and folic acid (FeFol) tablet (usual care, referent group), (b) MMN tablet, (c) PE LNS, and (d) PE + MMN LNS...

Autophagy is a cytoplasmic degradation system that is important for starvation adaptation and cellular quality control. Previously, we reported that Atg5-null mice are neonatal lethal; however, the exact cause of their death remains unknown. Here, we show that restoration of ATG5 in the brain is sufficient to rescue Atg5-null mice from neonatal lethality. This suggests that neuronal dysfunction, including suckling failure, is the primary cause of the death of Atg5-null neonates, which would further be accelerated by nutrient insufficiency due to a systemic failure in autophagy...

Iron deficiency (ID), with and without anemia, affects an estimated 2 billion people worldwide. ID is particularly deleterious during early-life brain development, leading to long-term neurological impairments including deficits in hippocampus-mediated learning and memory. Neonatal rats with fetal/neonatal ID anemia (IDA) have shorter hippocampal CA1 apical dendrites with disorganized branching. ID-induced dendritic structural abnormalities persist into adulthood despite normalization of the iron status. However, the specific developmental effects of neuronal iron loss on hippocampal neuron dendrite growth and branching are unknown...

BACKGROUND: Infants are at particular risk of iron-deficiency anemia. We investigated the changes in the blood count of mother and infant as well as the relationship between them and the relationship between an infant's nutrition method and infant anemia. METHODS: This retrospective cohort study included healthy neonates born between August 2011 and July 2014 in St. Luke's International Hospital, Tokyo, Japan. Data from blood samples of mothers obtained during late pregnancy and those of infants obtained at birth and at the age of 3, 6, and 9 months were analyzed...

BACKGROUND: Incompatibility between parental platelet (PLT) antigens may lead to sensitization of mother and development of fetal and neonatal alloimmune thrombocytopenia (FNAIT) resulting in fetal thrombocytopenia. Intravenous immunoglobulin (IVIG) with or without prednisone is the most effective, evidence-based antenatal treatment for subsequent FNAIT-affected pregnancies. IVIG infusion causes hemolysis in other settings, the degree depending upon patient blood groups (BGs). STUDY DESIGN AND METHODS: In ClinicalTrials...

The effects of cadmium (Cd) were evaluated in offspring exposed from birth until weaning (neonatal day 0-21) and 4 weeks after exposure cessation focusing on iron (Fe) and zinc (Zn) levels in organs and hematological parameters. Wistar female rats were administered 50mg Cd/L in drinking water (Cd-exposed) for 4 weeks before mating and during 3 weeks of gestation plus 3 weeks of lactation. Controls were supplied drinking water. At birth, part of Cd-exposed dams' litters was cross-fostered to control dams (CCd group) and their control litters were cross-fostered to Cd-exposed dams (CdC group)...

Over several decades, asthma has evolved from being recognized as a single disease to include a diverse group of phenotypes with dissimilar natural histories, pathophysiologies, responses to treatment, and distinctive molecular pathways. With the application of Occam's razor to asthma, it is proposed that there is one cause underlying the numerous phenotypes of this disease and that the responsible molecular pathway is a deficiency of iron in the lung tissues. This deficiency can be either absolute (e.g. asthma in the neonate and during both pregnancy and menstruation) or functional (e...

BACKGROUND: Little attention has been placed on the unique iron demands that may exist in women with multiple gestations. This merits attention because iron deficiency (ID) during pregnancy is associated with adverse pregnancy outcomes that are known to be more prevalent in multiple births. OBJECTIVE: We characterized longitudinal changes in iron status across pregnancy in a cohort of healthy women with multiple gestations and identified determinants of maternal ID and anemia...
