Neuroinflammation in utero may result in life-long neurological disabilities. Microglia play a pivotal role, but the mechanisms are poorly understood. No early postnatal treatment strategies exist to enhance neuroprotective potential of microglia. We hypothesized that agonism on α7 nicotinic acetylcholine receptor (α7nAChR) in fetal microglia will augment their neuroprotective transcriptome profile, while the antagonistic stimulation of α7nAChR will achieve the opposite. Using an in vivo - in vitro model of developmental programming of neuroinflammation induced by lipopolysaccharide (LPS), we validated this hypothesis in primary fetal sheep microglia cultures re-exposed to LPS in presence of a selective α7nAChR agonist or antagonist...

BACKGROUND: Calls for public reporting of outcomes in congenital heart surgery have led to several different reporting schemes, including a star rating system and benchmark procedure-specific mortality data tables. Important unanswered questions remain about the optimal format and content of public reporting of congenital heart surgery outcomes. METHODS: In conjunction with three parent advocacy groups, we developed a questionnaire to gauge parents' attitudes regarding the format and content of an "optimal" public reporting scheme...

Early-life iron deficiency is a common nutrient condition worldwide and can result in cognitive impairment in adulthood despite iron treatment. In rodents, prenatal choline supplementation can diminish long-term hippocampal gene dysregulation and neurocognitive deficits caused by iron deficiency. Since fetal iron status is generally unknown in humans, we determined whether postnatal choline supplementation exerts similar beneficial effects. Male rat pups were made iron deficient (ID) by providing pregnant and nursing dams an ID diet (3-6ppm Fe) from gestational day (G) 3 through postnatal day (P) 7, and an iron-sufficient (IS) diet (200ppm Fe) thereafter...

Vertebrate respiratory chain complex III consists of eleven subunits. Mutations in five subunits either mitochondrial (MT-CYB) or nuclear (CYC1, UQCRC2, UQCRB, and UQCRQ) encoded have been reported. Defects in five further factors for assembly (TTC19, UQCC2, and UQCC3) or iron-sulphur cluster loading (BCS1L and LYRM7) cause complex III deficiency. Here, we report a second patient with UQCC2 deficiency. This girl was born prematurely; pregnancy was complicated by intrauterine growth retardation and oligohydramnios...

BACKGROUND: Anemia affects up to 42% of gravidas. Neonatal iron deficiency is associated with low birth weight, delayed growth and development, and increased cognitive and behavioral abnormalities. While oral iron is convenient, up to 70% report significant gastrointestinal toxicity. Intravenous iron formulations allowing replacement in one visit with favorable side-effect profiles decrease rates of anemia with improved hemoglobin responses and maternal fetal outcomes. METHODS: Seventy-four oral iron-intolerant, second- and third-trimester iron-deficient gravidas were questioned for oral iron intolerance and treated with intravenous iron...

BACKGROUND: Reticulocyte haemoglobin content, i.e., the reticulocyte equivalent (Ret-He), seems to be a promising parameter for the detection of iron deficiency (ID) in neonates because it can be obtained as part of a reticulocyte count, with no additional blood loss and at no extra cost. Due to the short life span of reticulocytes, Ret-He reflects current iron availability for erythropoiesis more accurately than other common erythrocyte indices. OBJECTIVE: We aimed to evaluate postnatal changes in Ret-He within the first days after birth in term and preterm infants with the hypothesis that preterm infants experience a more pronounced postnatal reduction in Ret-He when compared to term infants...

To date, there is limited knowledge of the effects that abnormal sea surface temperature (SST) can have on the physiology of neonate pinnipeds. However, maternal nutritional deficiencies driven by alimentary restrictions would expectedly impact pinniped development and fitness, as an adequate supply of nutrients is essential for growth and proper functioning of all body systems, including red blood cell synthesis and clearance. Here, we investigated red blood cell morphology of California sea lion (CSL) pups from the San Benito Archipelago born during the 2014 and 2015 anomalously high SST events recorded in the northeastern Pacific Ocean...

Parkinson's disease (PD) is the most common neurodegenerative movement disorder, and its causes remain unknown. A major hallmark of the disease is the increasing presence of aggregated alpha-synuclein (aSyn). Furthermore, there is a solid consensus on iron (Fe) accumulation in several regions of PD brains during disease progression. In our study, we focused on the interaction of Fe and aggregating aSyn in vivo in a transgenic mouse model overexpressing human aSyn bearing the A53T mutation (prnp.aSyn.A53T). We utilized a neonatal iron-feeding model to exacerbate the motor phenotype of the transgenic mouse model...

A Lapillonne, O Becquet
Because of the postnatal redistribution of the iron store, the term infant born after an uneventful pregnancy virtually needs no iron during its first 6 months of life. On the other hand, several factors, such as duration of gestation, gender, mother's iron status, alteration of the iron placental transfer, significantly influence the iron store at birth. Because of their reduced body store at birth and their higher demand during catch-up growth, low birth weight infants should receive an iron supplement, which should be started earlier and given at a higher dose in the more premature infants...

Cyp1b1 deletion and gestational vitamin A deficiency (GVAD) redirect adult liver gene expression. A matched sufficient pre- and post-natal diet, which has high carbohydrate and normal iron content (LF12), increased inflammatory gene expression markers in adult livers that were suppressed by GVAD and Cyp1b1 deletion. At birth on the LF12 diet, Cyp1b1 deletion and GVAD each suppress liver expression of the iron suppressor, hepcidin (Hepc), while increasing stellate cell activation markers and suppressing post-natal increases in lipogenesis...
