Prenatal attachment in women subjected to fetal echocardiography
2012
ackground The experience of fetal echocardiography (as advanced level screening, usually done between 19th and 23rd week of gestation) is a complex psychological condition for mothers. It can influences the relationship they structure with themselves and their future children. Sometimes this examination can result in a diagnosis of fetal congenital heart disease. This event could be critical for the psychological representation of the child, made by mother, pushing her to an emotional blockage or hyper involvement (Righetti, Di Bernardo, Maggino, 2008) . In continuity with specific studies on this topic (ibidem), this research study investigates the configuration of prenatal attachment bond…
The respiratory gas values of the fetal and maternal blood in cartesian nomograms
1966
Respiratory gas values of maternal and fetal blood taken at delivery are represented in two Cartesian nomograms. They are based on data, published by vogel, fischer und thews (1965) and Fischer, Vogel und Thews (1965). The nomograms depict the interdependence of O2 pressure, O2 content, CO2 pressure and CO2 content, established by the O2 and CO2 dissociation curves, as well as by the Bohr effect and the Haldane effect. If two of the values are known, the remaining ones can be read from the nomograms.
Pollutant concentrations in placenta.
2011
Unborn children are exposed to environmental pollutants via the placenta, and there is a causal relationship between maternal intake of pollutants and fetal exposure. Placental examination is an effective way for acquiring data for estimating fetal exposure. We analyzed the concentrations of 104 congeners of persistent organic pollutants, seven organotin compounds, five heavy metals, and methylmercury in 130 randomly selected placentas. Additionally, we examined similarities between pollutant concentrations by analyzing correlations between their placental concentrations. Our results yield new information for conducting contaminant risk assessments for the prenatal period. Out of the 117 in…
Oxidative stress in asphyxiated term infants resuscitated with 100% oxygen
2003
Although room air is adequate for resuscitating asphyxiated newborn infants, guidelines recommend using 100% oxygen. Hyperoxemia, as has been noted in animal studies, could cause delayed breathing, increased oxygen consumption, and disordered cerebral circulation. In addition, 100% oxygen has caused prolonged oxidation of blood glutathione in neonates. In this study, 51 asphyxiated neonates born at term were randomly assigned to resuscitation with room air (RAR) and 55 to resuscitation with 100% oxygen (OxR). The goal was to learn whether using oxygen for resuscitation triggers oxidative stress. Critical criteria were the Apgar score, the time of the first cry, and sustained respiration. Si…

Wharton’s Jelly Mesenchymal Stromal Cells Support the Expansion of Cord Blood–derived CD34+Cells Mimicking a Hematopoietic Niche in a Direct Cell–cel…
2018
Wharton’s jelly mesenchymal stromal cells (WJ-MSCs) have been recently exploited as a feeder layer in coculture systems to expand umbilical cord blood–hematopoietic stem/progenitor cells (UCB-HSPCs). Here, we investigated the role of WJ-MSCs in supporting ex vivo UCB-HSPC expansion either when cultured in direct contact (DC) with WJ-MSCs or separated by a transwell system or in the presence of WJ-MSC–conditioned medium. We found, in short-term culture, a greater degree of expansion of UCB-CD34+cells in a DC system (15.7 ± 4.1-fold increase) with respect to the other conditions. Moreover, in DC, we evidenced two different CD34+cell populations (one floating and one adherent to WJ-MSCs) with …
Atrial Natriuretic Peptide presence in parotid gland of human fetus at 13th week of development and in adult man
2013
Our immunohistochemical study shows that atrial natriuretic peptide (ANP) is present in both human fetal and adult parotid gland. In the fetuses ANP is localized in cell clusters, while in adult parotid gland, the ANP is seen only in the wall of intra- and extralobular ducts. The results suggest that ANP might play a role in the differentiation of the parotid gland similarly as in brain and that during fetal growth ANP may play a role in the regulating the secretion of primitive salivary fluid, even if acini are still not developed.

A study on maternal-fetal attachment in pregnant women undergoing fetal echocardiography
2017
Purpose: To investigate the possible effects of the fetal echocardiography experience on the prenatal attachment process. The predictive effect of specific women’s psychological variables will be explored as well. Design and methods: This between groups study involved 85 women with pregnancy at risk who underwent the fetal echocardiography, and 83 women who were about to undergo the morphological scan. The tools employed were: the Prenatal Attachment Inventory (P.A.I.) to explore the maternal-fetal attachment; the Maternity Social Support Scale to investigate the woman perception of being socially supported during pregnancy; both the Big Five Questionnaire and the FACES III to explore the p…
