OBJECTIVE: Growth Arrest-Specific 6 (GAS6) is a vitamin K-dependent protein. Despite a similar structure to Protein S, it has no anticoagulant activity. An association between GAS6 and some diseases for adults has been reported. In the absence of prospective clinical studies of GAS6 in neonates, so far, the objective of this study is to obtain, for the first time, plasma GAS6 levels before and after vitamin K1 prophylaxis in full-term and pre-term newborns. METHODS: 80 newborn (40 term and 40 preterm) were recruited for this study...

Background: Vitamin A (VA; retinol) supplementation is used to reduce child mortality in countries with high rates of malnutrition. Existing research suggests that neonates (<1 mo old) may have a limited capacity to store VA in organs other than the liver; however, knowledge about VA distribution and kinetics in individual, nonhepatic organs is limited.Objective: We examined retinol uptake and turnover in nonhepatic organs, including skin, brain, and adipose tissue, in neonatal rats without and after VA supplementation...

To systematically evaluate the effectiveness of prothrombin complex concentrate (PCC) in neonates and infants, we performed a systematic review and meta-analysis based on current evidence. Quality of studies was assessed by Cochrane Collaboration's risk of bias tool and Newcastle-Ottawa quality assessment scale. For dichotomous data, we obtained the number of events and total number and calculated the relative risk (RR) with 95% confidence intervals (CI). For continuous variables, we obtained mean and standard deviation (SD) values and calculated mean difference (MD) with 95% CI...

BACKGROUND: Iodine is an essential nutrient required for the biosynthesis of thyroid hormones, which are responsible for regulating growth, development and metabolism. Iodine requirements increase substantially during pregnancy and breastfeeding. If requirements are not met during these periods, the production of thyroid hormones may decrease and be inadequate for maternal, fetal and infant needs. The provision of iodine supplements may help meet the increased iodine needs during pregnancy and the postpartum period and prevent or correct iodine deficiency and its consequences...

Vitamin K plays an integral role in the clotting cascade. Deficiency, specifically in vulnerable neonates with insufficient stores, can lead to spontaneous bleeding and devastating effects. In this case, we report a young infant with late-onset vitamin K deficiency bleeding who did not receive vitamin K prophylaxis after birth. Initially presenting with bruising and fussiness, the patient was later found to have intracerebral hemorrhage with midline shift and uncal herniation. The infant was not a surgical candidate and died shortly thereafter...

In low-resource settings, such as rural Malawi, pregnant women are prone to energy and micronutrient deficiencies with the consequence of delivering low-birth weight infants with higher risks of morbidity and mortality. This study aimed to examine the association between maternal dietary intakes during pregnancy and infant birth size. Dietary intakes of 203 pregnant women were assessed between 28 and 35 weeks of gestation and their infants' (n = 132) birth size measured. Intakes of energy, macronutrients, and 11 micronutrients were estimated using a 3-day interactive 24-hr diet recall...

Pregnancy represents a time of rapid bodily change, which includes physical proportions, physiology and responsibility. At this context, maternal vitamin D stores have been the objective of extensive scientific research during the last decades, focusing on their potential effects on maternal an neonatal health. A growing body of observational studies indicated that maternal hypovitaminosis D (as defined by maternal 25-hydroxyvitamin D [25(OH)D] levels <20 ng/ml or <50 nmol/l) is a significant risk factor for adverse neonatal outcomes including asthma, multiple sclerosis and other neurological disorders...

Few studies have examined how vitamin C status is affected in diabetic pregnancy and no comparison between normal and diabetic pregnancies has been found. This study evaluated vitamin C status prospectively during pregnancy in women with type 1 diabetes mellitus (n=76), in non-diabetic women (n=60), and in their respective neonates. Vitamin C was lower in diabetic women throughout all trimesters compared to controls (p<0.01). Repeated measurements analysis showed significant differences between diabetic and non-diabetic women; also when adjusted for birth weight ratio and age...

BACKGROUND: A major cause of perinatal morbidity and mortality has been reported to be preterm premature rupture of membranes (PPROM). Our objective was to evaluate oxidant-antioxidant balance, infection parameters, time interval between rupture of membranes and delivery (latency period), and the relationship among all these parameters. METHODS: Seventy-five cases with PPROM between 24 and 34 gestational weeks were included in the study. A control group of 41 women who gave birth at term were considered as the control group...

Observational studies suggest an adverse effect of maternal hypovitaminosis D during pregnancy. However, intervention studies failed to show convincing benefit from vitamin D supplementation during pregnancy. With analytical advances, vitamin D can now be measured in ten forms-including as epimers-which were thought to be biologically inactive, but can critically impair immunoassays. The aim of this commentary is to highlight the potential clinical and analytical significance of vitamin D epimers in the interpretation of vitamin D roles in pregnancy...

The calcium-sensing receptor (CaSR) plays a pivotal role in systemic calcium metabolism by regulating parathyroid hormone secretion and urinary calcium excretion. The diseases caused by an abnormality of the CaSR are genetically determined or are more rarely acquired. The genetic diseases consist of hyper- or hypocalcemia disorders. Hypercalcaemia disorders are related to inactivating mutations of the CASR gene either heterozygous (autosomal dominant familial benign hypercalcaemia, still named hypocalciuric hypercalcaemia syndrome type 1) or homozygous (severe neonatal hyperparathyroidism)...

PURPOSE: Evaluation of ketogenic diet (KD) therapies for seizure control during pregnancy when safety and appropriate management become considerations. Until now, no information has been available on seizure reduction and human pregnancy related outcomes in women treated with KD therapies. METHOD: We describe two cases of pregnant women with epilepsy treated with KD therapy either as monotherapy (Case 1) or as adjunctive therapy (Case 2). RESULTS: Case 1: A 27 year old woman, gravida1, started the classic KD with medium chain triglyceride (MCT) emulsion and 75g carbohydrate-restriction, later reduced to 47g...

BACKGROUND: Vitamin D has neuroprotective and immunomodulatory properties, and deficiency is associated with worse stroke outcomes. Little is known about effects of hypoxia-ischemia or hypothermia treatment on vitamin D status in neonates with hypoxic-ischemic encephalopathy (HIE). We hypothesized vitamin D metabolism would be dysregulated in neonatal HIE altering specific cytokines involved in Th17 activation, which might be mitigated by hypothermia. METHODS: We analyzed short term relationships between 25(OH) and 1,25(OH)2 vitamin D, vitamin D binding protein, and cytokines related to Th17 function in serum samples from a multicenter randomized controlled trial of hypothermia 33(0)C for 48h after HIE birth versus normothermia in 50 infants with moderate to severe HIE...

OBJECTIVES: Evidence suggests a beneficial effect of vitamin D on perinatal health; however, low vitamin D status is prevalent in pregnant women and neonates. The objective was to determine factors that are associated with vitamin D status of mothers in early pregnancy and neonates. METHODS: The study comprised 1,635 pregnant women from Quebec City and Halifax, Canada, 2002-2010. Vitamin D status was based on the concentration of 25-hydroxy-vitamin D [25(OH)D] determined with a chemiluminescence immunoassay in maternal sera collected at a median of 15 weeks' gestation and in neonatal cord sera at delivery...
