Abstract
Background Pregnancy represents a state of increased oxidative stress and antioxidants, in which selenium (Se) plays a pivotal role, contribute to maintain the oxidative balance. If antioxidant defenses are depleted, placental function is disrupted, resulting in pregnancy complications, including pregnancy-induced hypertension (PIH). Little is known about fetal selenium status in concomitant relation to maternal PIH, gestational age (GA) and birthweight (BW). Methods We examined over a 3-year period the serum (SeS) and urine selenium (SeU) status in term neonates from normotensive (nonPIH) and hypertensive (PIH) mothers as clinical markers of oxidative stress. In this retrospective observational study, 72 neonates with maternal PIH were matched for GA and BW to 72 neonates of normotensive mothers. Four groups were obtained, based on maternal PIH and BW relative to GA (appropriate-for-gestational-age-AGA, small-for-gestational-age-SGA): nonPIH-AGA (control group), nonPIH-SGA, PIH-AGA, and PIH-SGA. Results The results showed significant differences (p < 0.001) in selenium levels among the study groups: SeS - 44.85 ± 7.56 μg/L in nonPIH-AGA, 39.62 ± 11.42 μg/L in nonPIH-SGA, 40.01 ± 10.07 μg/L in PIH-AGA, and 25.39 ± 8.99 μg/L in PIH-SGA; SeU - 27.98 ± 7.99 μg/L in nonPIH-AGA, 22.85 ± 9.48 μg/L in nonPIH-SGA, 23.44 ± 6.73 μg/L in PIH-AGA, and 13.05 ± 5.86 μg/L in PIH-SGA. Selenium depletion was more common in neonates born from hypertensive mothers and those born small for gestational age. Though moderate in intensity, selenium levels were positively correlated with BW (0.319 for SeS, 0.397 for SeU) and negatively correlated with maternal systolic blood pressure (-0.313 for SeS, -0.324 for SeU). The main independent effects on SeS and SeU of each maternal blood pressure and birth weight turned out statistically significant. In interaction, a more pronounced effect was reached in PIH-SGA neonates. Conclusion Selenium status seemed to reflect the negative impact that PIH exerts in neonates during intrauterine development. Clinical markers of selenium status could thus be of great value for tracking responses of individuals to selenium supplementation as part of health improvement and harm mitigation approaches.

Abstract
BACKGROUND This study was performed to investigate lead levels in neonates born to the mothers suffering from opiate use disorder (OUD) and the association of lead levels with the Apgar score. METHODS The present cross-sectional study included 56 neonates who were referred to the neonatal ward of Amir-Al Momenin Hospital, Zabol. The neonates were divided into two groups: the neonates whose mothers suffered OUD and the control group. Data were collected using a researcher-prepared questionnaire, and blood lead level was determined using the atomic absorption method. Data were statistically analyzed. RESULTS In all, 56 neonates (28 from OUD mothers and 28 from the control mothers) were included in this study. Among the women with OUD, 16 (57%) used inhaled opium, while 12 (43%) consumed opium orally. There was a significant difference regarding Apgar score (9.76 ± 2.11 versus. 7.11 ± 4.21; p = 0.02) and the neonate's blood lead level (2.33 ± 1.3 µg/dl versus 7.33 ± 5.9 µg/dl) between the control and OUD groups (p < 0.001). The odds ratio of abnormally elevated blood lead level rose with increasing duration of maternal opiate disorder for opiate usage durations of 3 to 5 years (adjusted odds ratio [OR] 42.82, 95% confidence interval [CI] 3.27-561, p = 0.004) and > 5 years (adjusted OR 45.5, 95% CI 2.97-698, p = 0.006). CONCLUSION The results of this study suggested a significant relationship between maternal opium consumption during pregnancy and neonatal serum lead levels, as well as decreased neonatal Apgar score.

Abstract
Fetuses are a high-risk group for methylmercury (MeHg) exposure. The main objective of this study was to compare the characteristic profiles of total mercury (THg), inorganic mercury (IHg), MeHg, and selenium in plasma and red blood cells (RBCs) between maternal and cord blood at parturition collected from a group of Japanese women. Furthermore, correlations of THg in RBCs, which is a biomarker of MeHg, and THg in plasma, which is an IHg exposure biomarker, were examined in maternal and cord blood. Fifty-five pairs of maternal and cord blood samples obtained at parturition were collected from pregnant women in Fukuoka, Japan. THg in RBCs and plasma were significant correlated between maternal and cord blood. THg in RBCs was 13.9 ng/mL for cord and 9.16 ng/mL for maternal blood, with a cord:maternal RBCs ratio for THg of 1.58, suggesting that MeHg is actively transferred from the mother to the fetus via the placenta. THg in plasma showed a positive correlation with THg in RBCs for maternal and cord blood. This result suggests that measuring THg in plasma can overestimate the exposure level to IHg in fish-eating populations. The percentages of IHg in cord plasma and RBCs were 31% and 1.7%, respectively, and those in maternal plasma and RBCs were 46% and 5.9%, respectively. These results suggest that cord blood is rich in MeHg and can easily transfer to the fetal brain. Selenium in cord plasma was 67 ng/mL and that in maternal plasma was 97 ng/mL, with a cord:maternal plasma ratio for Se of 0.69, suggesting that the protective effects of Se against MeHg toxicity in fetuses may be weaker than those expected in adult mothers.

Abstract
The aim of the study was to evaluate Hg and Se concentrations and Se:Hg molar ratios in the placenta, umbilical cord and fetal membranes, and to examine the relationship between the concentrations of the elements and selected factors. The study material consisted of the placenta, umbilical cord and fetal membranes obtained from 91 healthy women from northwestern and central Poland. In our study mean Hg and Se concentrations in afterbirth were ~ 0.01 mg/kg dry weight (dw) and ≤ 0.5 mg/kg dw, respectively. Correlation analysis showed negative relationships between placenta weight and Se concentration in the placenta and umbilical cord, as well as between placenta length and Se levels in the umbilical cord. We found negative correlations between THg concentration in the placenta and birth weight and between Se concentration in the placenta and umbilical cord and the morphological parameters of the placenta. Furthermore, we noted new types of interactions in specific parts of the afterbirth. In our study, Se:THg molar ratios ranged from 5 to 626; these values indicate protection against Hg toxicity.

Abstract
BACKGROUND Neonatal mortality continues to be a significant problem in the Indian setting, especially in very low birth weight (VLBW) neonates. Selenium (Se) has been shown to possess antioxidant properties, and some recent studies have shown a reduction in the sepsis-attributable neonatal mortality with its use. India is a Se-deficient country. Blood Se concentrations in newborns are lower than those of their mothers and lower still in preterm infants. OBJECTIVE To evaluate the efficacy of Se in preventing the first episode of late-onset sepsis in VLBW preterm neonates. METHODS Ninety neonates weighing <1500 g and period of gestation <32 weeks, asymptomatic at birth and admitted to the neonatal intensive-care unit (NICU) in the first 12 h of birth with no maternal risk factors for sepsis were analyzed in the study. Se or placebo was supplemented orally once daily from 1st to 28th day of life to the test (n = 45) or control (n = 45) groups, respectively, followed by daily clinical assessment for signs or symptoms of sepsis in the hospital and weekly after discharge. RESULTS Preterm VLBW neonates (mean birth weight 1464.22 ± 50.14 g and mean gestational age 221.75 ± 4 days) are Se deficient at birth, with mean (SD) Se levels 31.1 ± 14.8 µg/l. Se supplementation at 10 µg/day increased serum Se levels significantly (63.9 ± 13.9 µg/l on Day 28 in Se vs. 40.9 ± 17.3 on Day 28 in placebo; p < 0.01). The incidence of the first episode of culture-proven late-onset sepsis was significantly lower in the Se than in the placebo group. [0/45 (0%) in Se vs. 6/45 (13.3%) in placebo; p = 0.033]. The incidence of probable sepsis was found to be significantly lower in the Se group [7/45 (15.55%)] than in the placebo [16/45 (35.55%)]; p = 0.02. The total incidence of any late-onset sepsis (i.e. culture-proven plus probable sepsis) was also significantly reduced by Se supplementation. [7/45 (15.55%) in Se vs. 22/45 (48.88%) in placebo; p = 0.001]. CONCLUSION Preterm VLBW neonates are Se deficient at birth. Se supplementation at 10 µg/day resulted in getting the Se levels into the acceptable normal level and reduced the incidence of the first episode of late-onset sepsis in these neonates.

Abstract
UNLABELLED Perinatal hypoxic-ischemic encephalopathy (HIE) is an important cause of brain injury in the newborn and can result devastating consequences. The principle mechanisms underlying neurological damage in HIE resulting from hypoxemia and/or ischemia is deprivation of glucose and oxygen supply which energy failure. A consequent reperfusion injury often deteriorates the brain metabolism by increasing the oxidative stress damage. Selenium is a constituent of the antioxidant enzyme Glutathione peroxidase and is vital to antioxidant defense. This study aimed to measure the serum selenium levels in full term neonates with HIE and their mothers and to correlate between them and the severity of HIE. METHODS The study included 60 full term neonates with HIE admitted to NICU of Minia university hospital during the period from January 2014 to February 2015. Twenty apparently healthy full term neonates selected as a control group. After history taking and careful clinical examination; all neonates were subjected to: Complete blood count, renal and liver function tests and serum electrolytes. Serum selenium was measured for all neonates and their mothers within 48 h of life using atomic flame spectrophotometer method. RESULTS Neonates with HIE had significant lower serum selenium levels than normal healthy neonates (p = 0.001**) with the lowest levels in neonates with severe HIE but there were no significant differences between patients and controls as regards the maternal serum selenium levels. Significant negative correlations between serum selenium levels and the severity of HIE and base excess were present, while positive significant correlations were present with Apgar score and pH. There were no correlations between serum selenium levels and maternal serum selenium levels urea or creatinine levels. CONCLUSIONS Neonates with HIE had lower serum selenium level than normal healthy neonates which is not dependent on the maternal serum selenium levels and was negatively correlated with the severity of HIE.

Abstract
Existing evidence on the effects of manganese and selenium during fetal life on neurodevelopmental disorders is inadequate. This study aims to investigate the hypothesized relationship between fetal exposure to manganese and selenium and attention deficit hyperactivity disorder (ADHD) diagnosis in childhood. Children born between 1978 and 2000 with ADHD (n=166) were identified at the Department of Child and Adolescent Psychiatry in Malmö, Sweden. Controls from the same region (n=166) were selected from the Medical Birth Register and were matched for year of birth and maternal country of birth. Manganese and selenium were measured in umbilical cord serum. The median cord serum concentrations of manganese were 4.3μg/L in the cases and 4.1μg/L in the controls. The corresponding concentrations of selenium were 47 and 48μg/L. When the exposures were analyzed as continuous variables no associations between cord manganese or selenium concentration and ADHD were observed. However, children with selenium concentrations above the 90th percentile had 2.5 times higher odds (95% confidence interval 1.3-5.1) of having ADHD compared to those with concentrations between the 10th and 90th percentiles. There was no significant interaction between manganese and selenium exposure (p=0.08). This study showed no association between manganese concentrations in umbilical cord serum and ADHD. The association between ADHD diagnoses in children with relatively high cord selenium was unexpected and should be interpreted with caution.

Abstract
BACKGROUND Selenium is an essential trace element and as a component of selenoproteins it plays a key role as an antioxidant. We aimed to evaluate the effect of selenium supplementation during pregnancy on cord blood selenium content and lipid profile. METHODS This trial was performed on 166 eligible women who were randomized to receive 100 μg of selenium, as selenium-yeast (Se group) or a placebo-yeast tablet (placebo group). Umbilical cord blood samples were collected at the time of delivery and selenium concentration and lipid profile were measured. RESULTS Triglyceride levels were found to be significantly higher in the Se group than in the placebo group (p=0.01). However, no significant difference in cord blood selenium was observed between the groups nor were there any significant correlations between cord blood selenium and lipid profile parameters. CONCLUSION Our findings suggest that selenium supplementation in pregnant women may be associated with an increased cord-blood triglyceride level, although total cholesterol, low-density lipoprotein and high-density lipoprotein cholesterol levels did not change significantly. The clinical significance of the increased cord triglyceride concentration needs to be evaluated.

Abstract
Pregnancy places increased demands on the mother to provide adequate nutrition to the growing conceptus. A number of micronutrients function as essential cofactors for or themselves acting as antioxidants. Oxidative stress is generated during normal placental development; however, when supply of antioxidant micronutrients is limited, exaggerated oxidative stress within both the placenta and maternal circulation occurs, resulting in adverse pregnancy outcomes. The present paper summarises the current understanding of selected micronutrient antioxidants selenium, copper, zinc, manganese, and vitamins C and E in pregnancy. To summarise antioxidant activity of selenium is via its incorporation into the glutathione peroxidase enzymes, levels of which have been shown to be reduced in miscarriage and preeclampsia. Copper, zinc, and manganese are all essential cofactors for superoxide dismutases, which has reduced activity in pathological pregnancy. Larger intervention trials are required to reinforce or refute a beneficial role of micronutrient supplementation in disorders of pregnancies.

Abstract
AIM To evaluate selenium (Se) and copper (Cu) concentrations in Greek and Albanian immigrant mothers and in the cord blood of their newborns. SUBJECTS AND METHODS From 1118 Greek and 820 Albanian mothers and from the cord blood of their neonates blood was obtained for Se and Cu measurement. Se and Cu concentrations were determined in sera with graphite furnace atomic absorption spectroscopy (GFAAAS) and atomic absorption spectrometry, respectively. In all, 30 days' nutrient intakes were evaluated in both groups. RESULTS Animal protein, Se and Cu intakes were poor in the Albanians vs the Greeks (P < 0.001). Se concentrations in the Greek mothers (68.3 +/- 8.5 microg/l) and in their newborns (37.02 +/- 8.9 microg/l) were found higher as compared with those in Albanian mothers (37.4 +/- 9.9 microg/l) and in their newborns (34.3 +/- 9.1 microg/l) (P < 0.001). Cu levels were also found higher (P < 0.001) in the Greek mothers (1687 +/- 353 microg/l) and in their neonates (449 +/- 87 microg/l) compared with those in the Albanian mothers (959 +/- 318 microg/l) and in their newborns (229 +/- 67 microg/l). Additionally, 31.5% of neonates born to Albanian women with Se concentrations less than 28 microg/l had higher Se levels (P < 0.01) than their mothers. CONCLUSIONS The low Se and Cu levels evaluated in the Albanian mothers and their newborns could be related to their poor animal protein intake which could be the consequence of their low socioeconomic status. As an effective preventive measure, accurate dietetic strategies to assess the requirements of pregnant immigrant women for trace elements may be planned in Greece.

Abstract
Pycnogenol (PYC), a patented combination of bioflavonoids extracted from the bark of French maritime pine (Pinus maritima), inhibits apoptosis and necrosis of developing neurons exposed acutely to ethanol (EtOH). The present study shows that the protective mechanisms of PYC in EtOH-exposed postnatal day 9 cerebellar granule cells (P9 CGCs) include (1) reduction of reactive oxygen species (ROS) production; (2) counteraction of suppressed copper/zinc superoxide dismutase (Cu/Zn SOD) and glutathione peroxidase/reductase (GSH-Px/GSSG-R) system activities; (3) upregulation of Cu/Zn SOD protein expression; (4) mitigation of the EtOH-mediated exacerbation of catalase (CAT) activity; and, (5) specific binding and inhibition of active caspase-3. These results indicate that the mechanisms by which PYC antagonizes EtOH-induced oxidative stress include oxidant scavenging and modulation of endogenous, cellular proteins. Using findings from the present and previous studies, a model delineating the mechanisms of EtOH effects on the system of antioxidant enzymes in developing CGCs is presented.

Abstract
Pycnogenol (PYC), a patented combination of bioflavonoids extracted from the bark of French maritime pine (Pinus maritima), scavenges free radicals and promotes cellular health. The protective capacity of PYC against ethanol toxicity of neurons has not previously been explored. The present study demonstrates that in postnatal day 9 (P9) rat cerebellar granule cells the antioxidants vitamin E (VE) and PYC (1) dose dependently block cell death following 400, 800, and 1600 mg/dL ethanol exposure (2) inhibit the ethanol-induced activation of caspase-3 in the same model system; and (3) reduce neuronal membrane disruption as assayed by phosphatidylserine translocation to the cell surface. These results suggest that both PYC and VE have the potential to act as therapeutic agents, antagonizing the induction of neuronal cell death by ethanol exposure.
