Factors Predisposing to Hypertension in Subjects Formerly Born Preterm: Renal Impairment, Arterial Stiffness, Endothelial Dysfunction or 
Something E…

2020

: Subjects formerly born preterm subsequently develop arterial - particularly isolated systolic- hypertension more frequently than their peers born at term. : Numerous factors may influence this predisposition, including an incomplete nephrogenesis, implying the presence of kidneys with a reduced number of nephrons and consequent reduction in haematic filtration, increased sodium absorption and activation of renin-angiotensin-aldosterone system, increased arterial rigidity produced by an elastin deficiency previously observed in anatomic specimens of human immature aorta, and reduced endothelial nitric oxide excretion, due to high blood levels of ADMA, a strong direct inhibitor of nitric o…

Opolskie voivodeship secondary school students’ knowledge about fetal alcohol syndrome and its determinants

2019

Background: Alcohol consumption during pregnancy may result in a wide range of morphological and neurodevelopmental abnormalities, most notably fetal alcohol syndrome (FAS). Objectives: To evaluate: (1) Opolskie Voivodeship high school students’ level of knowledge on the subject of FAS (2) the factors contributing to this level of knowledge (3) sources of information about FAS which are accessible and preferred by secondary school students. Materials and methods: The study was conducted in 2018 among 228 adult students of Opole secondary schools. The authors used a diagnostic survey based on original questions they developed for the study. The students’ knowledge was assessed using a four-l…

Dilation of the ductus venosus by stent implantation increases placental blood perfusion in fetal sheep.

2006

The reduction of resistance to flow in the ductus venous (DV) and a decrease of blood supply to the liver serve for the survival of the fetus during hypoxia. The present study investigated the influence of the increased diameter of the DV on placental blood perfusion.In 15 ewes with twin pregnancies at gestational ages of 117 +/- 4 days, a stent (4 or 5 mm) was placed into the DV of 1 twin (DV(stent) group) under ultrasound guidance. Blood flow rates in the umbilical vein (UV) and DV of both fetuses were measured using Doppler ultrasound. Eight pairs of twin fetuses were included for the final analysis.The dilatation of the DV increased the blood flow volume rate passed through the DV from …

Spontaneous labour at term is associated with fetal monocyte activation.

1999

SUMMARYThe aetiology of both term and preterm labour remains incompletely understood. Maternal infectious diseases as well as intra-uterine infections were shown to be a well established cause of uncontrollable preterm delivery, indicating that inflammatory reactions, regulated by maternal immunecompetent cells, are implicated in labour-promoting mechanisms. To investigate the possibility that the activation of the fetal immune system may be involved in labour induction, we examined cytokine production patterns of different cord blood cell populations obtained from neonates after spontaneous onset of normal term labour and vaginal delivery (n = 25), vaginal delivery but induced term labour …

Cell-Free Fetal DNA and Non-Invasive Prenatal Diagnosis of Chromosomopathies and Pediatric Monogenic Diseases: A Critical Appraisal and Medicolegal R…

2022

Cell-free fetal DNA (cffDNA) analysis is a non-invasive prenatal diagnostic test with a fundamental role for the screening of chromosomic or monogenic pathologies of the fetus. Its administration is performed by fetal DNA detection in the mother’s blood from the fourth week of gestation. Given the great interest regarding its validation as a diagnostic tool, the authors have set out to undertake a critical appraisal based on a wide-ranging narrative review of 45 total studies centered around such techniques. Both chromosomopathies and monogenic diseases were taken into account and systematically discussed and elucidated. Not surprisingly, cell-free fetal DNA analysis for screening purposes …

Stippled epiphyses in fetal alcohol syndrome.

1990

We report on punctate epiphyseal calcifications (stippled epiphyses) in the fetal alcohol syndrome and present the differential diagnosis of chondrodysplasia punctata. A literature survey shows that epiphyseal calcifications accompanying alcoholic embryopathy are regularly located in the lower limbs and rarely found in the upper extremities.
