Selenium in the full-term and premature newborn infant

The following observations can be made on the basis of findings relating to selenium in serum samples taken from 55 neonates (35 born at term and 20 born pre-term): 1) the blood concentration of selenium in neonates born at term showed no substantial difference to that reported by other authors; moreover, there were no sex or birthweight-dependent variations, and no correlations were found with either the mother's age or the mode of engendering procreation; 2) the blood concentration of selenium in neonates born pre-term was 30% lower than that found in neonates born at term; it was correlated with gestational age and birthweight, but not with sex, mother's age or the mode of engendering procreation. It will be worthwhile continuing these tests in order to identify possible therapeutic uses of selenium in cases of deficiency.
