The study was carried out on 23 samples of amniotic fluid taken between 35th and 39th week of pregnancy from 23 pregnant women with arterial hypertension (13 cases of hypertension induced by pregnancy, 5 cases of primary hypertension and 5 cases of hypertension accompanying renal diseases). Seven women undergoing the study gave birth to newborns with symptoms of delayed intrauterine growth below 10 centile (group examined), 16 mothers gave birth to eutrophic babies (control group). In the amniotic fluid of the group examined, bilirubin revealed a significantly higher level. The authors found no changes in the concentrations of ammonia, ions H+ and HPL between the group examined and the control group whereas they were able to observe a significantly lower level of glucose and oestrogens in the amniotic fluid in case of delayed intrauterine foetal growth.

Objective: This study explores a hybrid approach to maternal-fetal care for gestational diabetes (GD), integrating virtual visits seamlessly with in-clinic assessments. We assessed the feasibility, time efficiency, patient satisfaction, and clinical outcomes to facilitate wider adoption of maternal-fetal telemedicine.
Methods: We conducted a 4-week prospective study involving 20 women with GD at ≥32 weeks of pregnancy, alternating between remote and in-clinic weekly visits.

Background: The early colonization and establishment of the microbiome in newborns is a crucial step in the development of the immune system and host metabolism. However, the exact timing of initial microbial colonization remains a subject of ongoing debate. While numerous studies have attempted to determine the presence or absence of intrauterine bacteria, the majority of them have drawn conclusions based on sequencing data from maternal or infant samples taken at a single time point.

Neonatal Intensive Care Unit, G d'Annunzio University of Chieti, Italy.
Background: Adrenomedullin (AM) is a potent angiogenic, antioxidant and anti-inflammatory peptide protecting the developing lung from injury due to bronchopulmonary dysplasia (BPD) of the preterm infant. At this stage, no data on the potential effects of chorioamnionitis (CA) occurrence and glucocorticoids (GC) administration on AM in developing lungs are still lacking.
Objective: to investigate, in a sheep-based model, the positive/side-effects of combined exposure to CA and GC on AM concentrations measured in bronchoalveolar lavage fluid (BALF).
Medical student training with next-generation handheld ultrasound devices - hands on examination of fetal biometry in obstetrics.

Introduction: The technical development of ultrasound devices based on silicon chips has revolutionized ultrasound examinations, leading to the implementation of these portable handheld devices (PUD) in different medical fields. However, training on these devices is necessary to assure appropriate use and ensure valid results. While training programs for the use of conventional standard ultrasound devices (SUD) have been described, no training program for these handheld devices has been developed thus far.

Objective: Our study aimed to collect fetuses with recurrent 1q21.1 deletion or duplication syndrome for systematic clinical phenotype analysis to further delineate the intrauterine phenotype features of the two reciprocal syndromes.
Methods: Prenatal samples, including amniotic fluid and chorionic villus samples, were obtained by amniocentesis and chorionic villus sampling at our center, respectively.
