The purpose of this research was to study the binding capacity of estrogens to the sex hormone-binding globulin (SHBG) in mothers and their intrauterine malnourished newborns. Blood samples were obtained from mothers at delivery, and from babies, of the umbilical cord. SHBG was measured according to the method of Mickelson and Petra. It was found in mothers of malnourished babies that the binding capacity of serum protein to dehydrotestosterone (DHT) was significantly decreased in comparison to the controls (10.63 +/- 1.61 vs 13.25 +/- 2.18 micrograms DHT/dl serum, respectively), whereas it was significantly increased in intrauterine malnourished newborns (1.01 +/- 0.24 vs 0.77 +/- 0.18, respectively). These results suggest that SHBG decrease in mothers of intrauterine malnourished newborns occurs due to a decrease in the production of fetal adrenal hormone precursors and may, therefore, be a compensating mechanism to increase placental flow.

Intrauterine growth restriction (IUGR) caused by placental dysfunctions leads to fetal growth defects. Maternal microbiome and its metabolites have been reported to promote placental development. Milk fat globule membrane (MFGM) is known for its diverse bioactive functions, while the effects of gestational MFGM supplementation on the maternal gut microbiota, placental efficiency, and fetal development remained unclear.

Background/aim: Two retrospective studies of prospective cohorts showed doubled odds of birth asphyxia among women with low plasma vitamin D levels, and another study reported a four-fold increased risk of stillbirth. It was not known whether this was related to low sun exposure or to insufficient vitamin D per se. We aimed to assess if it was due to vitamin D status.

Objectives: The main goal of this study is to publish findings on the lifestyle factors of pregnant women in Hungary and their impact on early childhood health status by examining changes over time and regional/geographical disparities.
Methods: The source of the data is the raw indicators reported by health visitors as per mandatory annual report data for the period of 1997-2019. To examine the association, we used indicators of pregnant women's states as explanatory variables (for example, pregnant women in very late care, prenatal smoking habits, and pregnant women without care), and the outcome indicators were prematurity, intrauterine malnutrition, and newborn babies with developmental disorders.

Many children suffer from neurodevelopmental aberrations that have long-term effects. To understand the consequences of pathological processes during particular periods in neurodevelopment, one has to understand the differences in the developmental timelines of brain regions. The cerebellum is one of the first brain structures to differentiate during development but one of the last to achieve maturity.

Maternal hyperhomocysteinemia (HHcy) is a risk factor for intrauterine growth restriction presumably caused by a decrease in the placental transport of nutrients. We investigated the effect of experimental HHcy induced by daily methionine administration to pregnant rats on the free amino acid levels in the maternal and fetal blood, as well as on morphological and biochemical parameters associated with the amino acid transport through the placenta. HHcy caused an increase in the levels of most free amino acids in the maternal blood on gestational day 20, while the levels of some amino acids in the fetal blood were decreased.
