The Selenium Levels of Mothers and Their Neonates Using Hair, Breast Milk, Meconium, and Maternal and Umbilical Cord Blood in Van Basin

Abstract

The objective of the present study is to calculate linear regressions between a mother and her child with respect to their selenium concentration (ng/g) in the following traits: maternal blood and umbilical cord blood, maternal and child hair, maternal milk and child umbilical cord blood, maternal milk and meconium, maternal blood plasma, and child meconium. The data were collected at Research Hospital of the University of Yüzüncü Yil from 30 pairs of mothers and their newborn baby. The mean maternal serum Se level in 30 mothers was 68.52 +/- 3.57 ng/g and cord plasma level was 119.90 +/- 18.08 ng/g. The Se concentration in maternal and neonatal hair was 330.84 +/- 39.03 and 1,124.76 +/- 186.84 ng/g, respectively. The Se concentration of maternal milk at day 14 after delivery was determined as 68.63 +/- 7.78 ng/g (n = 13) and the concentration of Se was 418.90 +/- 45.49 ng/g (n = 22) for meconium of neonatal. There was no significant difference between maternal blood and milk Se levels. However, hair Se concentration was significantly higher than milk and maternal blood Se level. For each trait comparison, the average absolute difference in log(10)-transformed Se concentration was calculated between a mother and her child. The observed average absolute difference was compared with a test distribution of 1,000 resampled bootstrap averages where the number of samples was maintained but the relationship between a mother and her child was randomized among samples (alpha = 0.05).

Ethanol Consumption by Wistar Rat Dams Affects Selenium Bioavailability and Antioxidant Balance in Their Progeny

“…We assumed that one of the mechanisms that changes Se bioavailability in ethanol pups, apart from the lowest Se intake, is the action of ethanol on urine and hair Se concentration. So despite the fact that some authors defend that hair and claw Se concentration are a reflection of dietary Se status [16,17], our results agree with Salbe et al [18], who suggest that factors other than dietary Se intake affect hair and claw Se content and that these tissues should be used with caution for Se status assessment purposes.…”

Changes in the concentrations of biochemical indicators of diet and nutritional status of pregnant women across pregnancy trimesters in Trujillo, Peru, 2004–2005

“…Mean cord serum total iron binding capacity concentration for this study was 38.2 ± 6.75 μmol/L (216.6 ± 37.7 μg/dL), while a range of 36.4-48.5 μmol/L (203.5-271.0 μg/dL) has been reported for other studies [43,44]. Finally, mean cord serum selenium concentration for this study was 0.86 ± 0.11 μmol/L (68.2 ± 8.3 ng/mL) compared with 0.43-1.52 μmol/L (34.3–119.9 ng/mL) reported for other studies [45,46]. …”

“…One additional result of our study has been the information about the serum selenium levels of pregnant women in the region, which corroborates other studies conducted in Turkish pregnant women [34,35]. Despite the lack of a recommended borderline value, the whole group of patients seems to have low selenium levels [36].…”
