Abstract We determined reference values in umbilical cord plasma and erythrocytes for magnesium, total calcium, phosphorus, copper, and zinc, and then calculated correlations and stepwise-regression equations in 66 white full-term newborn infants (35 boys, 31 girls). Only infants meeting certain optimal criteria and benefiting from excellent maternal conditions and uncomplicated pregnancies were included. There were no significant sex-related differences at birth among the variables studied. Gestational age was positively correlated with erythrocyte zinc (P less than 0.001), and plasma calcium was positively correlated with erythrocyte copper (P less than 0.001). Plasma copper proved to be the most significant variable in the stepwise-regression equation for birth height as the dependent variable. The most significant regressors accounting for birth weight were erythrocyte zinc followed by plasma zinc.

ABSTRACT Objective: To determine the concentration of alpha-tocopherol in umbilical cord serum of full-term and preterm newborns, in order to assess the nutritional status of both groups in relation to the vitamin and its possible correlation with intrauterine growth. Methods: A cross-sectional observational study conducted with 140 newborns, of which 64 were preterm and 76 were full-term. They did not have any malformations, they came from healthy mothers, who were nonsmokers, and delivered a single baby. Intrauterine growth was evaluated by weight-to-gestational age at birth, using Intergrowth-21st. Thealpha-tocopherol levels of umbilical cord serum were analyzed by High Performance Liquid Chromatography. Results: The mean concentration of alpha-tocopherol in umbilical cord serum for preterm and full-term infants was 263.3±129.5 and 247.0±147.6 µg/dL (p=0.494). In the preterm group, 23% were small for gestational age, whereas in the full-term group, this percentage was only 7% (p=0.017). Low levels of vitamin E were found in 95.3% of preterm infants and 92.1% of full-term infants. There was no correlation between alpha-tocopherol levels and weight to gestational age Z score (p=0.951). Conclusions: No association was found between alpha-tocopherol levels and weight to gestational age at birth. Intrauterine growth restriction was more frequent in preterm infants and most infants had low levels of vitamin E at the time of delivery.

Carotenoids are antioxidant nutrients with the potential to provide protection against oxidative stress. Plasma carotenoid concentrations are lower in newborn infants compared to their mothers; however, limited information is available regarding how concentrations differ by gestational age. The objective of this research is to assess maternal and umbilical cord plasma carotenoid concentrations and maternal-umbilical cord plasma ratios across five groups of birth gestational age. Mother-infant dyads were enrolled at delivery for collection of maternal and umbilical cord blood. Plasma carotenoids were analyzed by HPLC and LC-MS/MS. Birth gestational age was categorized into five groups, and the Kruskal–Wallis test compared carotenoid concentrations and maternal-umbilical cord plasma ratios between these groups. A p-value of < 0.05 was considered statistically significant. 370 mother-infant dyads were included, with most infants delivered at early term (20.3%) or term (64.6%). Though maternal plasma concentrations increased with birth gestational age, we observed less variability in umbilical cord plasma concentrations, thus the maternal-umbilical cord plasma ratio also increased with birth CGA groups for lutein + zeaxanthin (p = 0.008), β-cryptoxanthin (p = 0.027), α-carotene (p = 0.030); β-carotene approached significance (p = 0.056). Additional research is needed to determine if carotenoid concentrations were physiologic to varying gestational ages or if they were impacted by factors associated with preterm birth.

AbstractHigher 1To compare IP-10 and ITAC levels in neonatal cord blood from gestations complicated by severe preeclampsia vs. gestational age-matched controls.Umbilical cord vessels were sampled following delivery of women with severe preeclampsia (n=30) ≥36 weeks to measure plasma IP-10 and ITAC levels and compared to corresponding controls matched for parity as well as maternal and gestational age. Chemokines were measured by specific ELISAs and expressed as pg/mL. Rho Spearman’s coefficients were calculated to establish correlations between chemokine values and various numeric variables.Preeclamptic cases displayed significantly lower median plasma umbilical artery and vein levels of both chemokines when compared to controls (IP-10: 23.4 vs. 31.4 and 2.0 vs. 24.6 pg/mL, P<0.05; and ITAC: 2.0 vs. 13.9 and 11.9 vs. 31.6 pg/mL, P<0.05, in artery and vein, respectively). There was a significant correlation between levels of both chemokines (rIn contrast to elevated 1

Relevance: The growth of neuropsychiatric diseases caused by perinatal pathology indicates the need to study the biochemical markers of brain damage in the newborn for the timely prevention of adverse consequences. Serotonin in early ontogenesis provides intensive development of neuronal structures and cortical networks involved in the mechanisms of formation of cyclic sleep organization a fine criterion of morphofunctional development of the brain. aim: The aim of the work is to study the content of serotonin in healthy full-term newborns in comparison with the quantitative and qualitative characteristics of the electropoligraphic sleep pattern. Material and methods: 84 healthy newborns were examined, which, depending on the gestational age, were divided into 3 groups: I 37 weeks (20 people), II 38 weeks (24 people), III 39-40 weeks (40 people). The content of serotonin in platelet-rich plasma of blood from the umbilical cord vein and in platelet suspension prepared from venous blood taken from mothers and children on the first day of life and again on day 5 was determined by high-performance liquid chromatography with electrochemical detection. A quantitative and qualitative analysis of the sleep electropoligram was performed 7-12 hours after birth. Results: The content of serotonin in platelet-rich plasma in umbilical cord blood in children does not depend on the method of birth, is 2 times lower than in the venous blood of mothers (0.379 0.116 microns/l, versus 0.756 0.200 microns/l, but there is a high correlation between the indicators (r = 0.8, p 0.05). At the gestational age of 39-40 weeks, the level of serotonin in platelet-rich plasma and in venous blood platelets is significantly higher than in those born at 37 weeks. In the latter, the increase in the content of serotonin in platelets continues after birth (at day 1, 0.539 0.149 nM/109 Tr, and on day 5 0.846 0.094 nM/109 Tr; p 0.05), whereas the indicators for those born at 39-40 weeks of pregnancy. They do not change (0.797 0.190 nM/109 Tr and 0.749 0.142 nM/109 Tr, respectively). A significant increase in the content of serotonin in the platelet-rich plasma and in the platelets of the child in the period from 37 to 39 weeks, both during intrauterine development and in the first days of life, correlates with an increase in the representation of the orthodox phase in the sleep cycle. Conclusion: The general pattern of changes in serotonin content and cyclic sleep organization in the early neonatal period in healthy newborns, depending on gestational age, indicates the possibility of using the obtained standard values of serotonin as a biochemical marker of functional brain development.

Colloid osmotic pressure of umbilical cord plasma was measured in 242 healthy infants, in 34 infants with respiratory distress syndrome (RDS), in 18 infants with asphyxia, in 13 infants who were small for gestational age, in 15 infants born to mothers with diabetes mellitus, and in 18 infants born to mothers with pregnancy-induced hypertension. In healthy infants, colloid osmotic pressure correlated highly significantly with umbilical cord blood total protein level, gestational age, and birth weight. In infants with RDS, no correlation between colloid osmotic pressure and gestational age or birth weight was found. Infants with RDS and gestational age between 36 and 38 weeks had significantly lower colloid osmotic pressure than healthy infants, whereas colloid osmotic pressure of infants with RDS and gestational age between 32 and 35 weeks did not differ from that of healthy infants of corresponding gestational age. Healthy term infants delivered by cesarean section had significantly lower colloid osmotic pressure than infants delivered vaginally. Infants with asphyxia had significantly higher colloid osmotic pressure than healthy infants. Colloid osmotic pressure is related to the lung maturity of the near-term and term neonate. Infants with a colloid osmotic pressure greater than 16 mm Hg are unlikely to develop RDS.

Extremely Preterm

Language delay (LD) and its relationship with later language impairment in preterm children is a topic of major concern. Previous studies comparing LD in preterm (PT) and full-term (FT) children were mainly carried out with samples of extremely preterm and very preterm children (sometimes with additional medical problems). Very few of them were longitudinal studies, which is essential to understand developmental relationships between LD and later language impairment. In this study, we compare the prevalence of LD in low-risk preterm children to that of FT children in a longitudinal design ranging from 10 to 60 months of age. We also analyze which variables are related to a higher risk of LD at 22, 30 and 60 months of age. Different language tests were administered to three groups of preterm children of different gestational ages and to one group of full-term children from the ages of 10 to 60 months. ANOVA comparisons between groups and logistic regression analyses to identify possible predictors of language delay at 22, 30 and 60 months of age were performed. The results found indicate that there were practically no differences between gestational age groups. Healthy PT children, therefore, do not have, in general terms, a higher risk of language delay than FT children. Previous language delay and cognitive delay are the strongest and longest-lasting predictors of later language impairment. Other factors, such as a scarce use of gestures at 10 months or male gender, affect early LD at 22 months of age, although their effect disappears as children grow older. Low maternal education appears to have a late effect. Gestational age does not have any significant effect on the appearance of LD.
