Objective: This prospective study aims to analyze the relation between particulate matter (PM) exposure during pregnancy and birth weight (BW), placental weight (PW) and umbilical artery PH (UAPH).
Study Design: Population included 3614 women born in Italy, living in Lombardia Region, consecutively admitted to the Clinica Mangiagalli for an elective cesarean section from January 2004 through December 2006. Outdoor air quality data were provided by the Department of the Regional Environmental Protection Agency and obtained by a network of fixed monitoring stations representatively distributed in eight geographical areas.
Results And Conclusion: Birth weight was negatively associated with exposure to PM concentration during the first trimester of pregnancy (mean change -22.2 g, 95%CI -8.7 to -35.7, p = 0.0013). Placental weight and umbilical artery PH were not associated with exposure to PM concentration. Fetal weight was negatively associated with exposure to PM concentration during the first trimester of pregnancy.

Fetal Isolated Single Umbilical Artery (ISUA) and Its Role as a Marker of Adverse Perinatal Outcomes.

Single umbilical artery (SUA) is considered an ultrasound marker of anomalies. Although it may be present in about 0.5% to 6% of normal pregnancies, it has been linked with an increased risk of fetal growth restriction (FGR), as well as cardiac, genitourinary and gastrointestinal malformations and chromosomal anomalies such as trisomies 21 and 18.

Background/objectives: This study identified early neonatal factors predicting pre-discharge mortality among extremely preterm infants (EPIs) or extremely low birth weight infants (ELBWIs) in China, where data are scarce.
Methods: We conducted a retrospective analysis of 211 (92 deaths) neonates born <28 weeks of gestation or with a birth weight <1000 g, admitted to University Affiliated Hospitals from 2013 to 2024 in Guangzhou, China. Data on 26 neonatal factors before the first 24 h of life and pre-discharge mortality were collected.
Proximate cord insertion in monochorionic twins with selective fetal growth restriction.

Division of Neonatology, Department of Pediatrics, Willem-Alexander Children's Hospital, Leiden University Medical Center, Leiden, The Netherlands.
Background: Monochorionic (MC) twins share a single placenta which can be unequally shared, leading to selective fetal growth restriction (sFGR). Limited data is available on the prevalence and clinical consequences of proximate cord insertion (PCI) in sFGR pregnancies.
Objective: We aimed to investigate the prevalence of PCI in MC placentas with and without sFGR and per type of sFGR, and study the placental characteristics and perinatal outcome of PCI in sFGR pregnancies.
Umbilical vein remodeling is associated with pregestational maternal overweight.

Introduction: Excess weight during pregnancy is a condition that can affect both mother and fetus, through the maternal-fetal interface, which is constituted by the placenta and umbilical cord. The umbilical vein is responsible for transporting oxygen and nutrients to the fetus, and its proper functioning depends on the integrity of its structure. The remodeling of the umbilical vein represents one of the causes of inadequate transport of nutrients to the fetus, being potentially harmful.

Background: Research into the mechanisms of growth control during birth and postnatal life has shown that adipose tissue regulates many physiological functions in the body by secreting adipokines. The aims of this study were to investigate the serum levels of visfatin and vaspin in healthy and unhealthy pregnant women and its relationship with their newborns' anthropometric measurements.
Materials And Methods: A total of 82 pregnant women were included in this study with their respective newborn) healthy pregnant women (n = 30), with obesity (n = 26) and with gestational diabetes (GD) (n = 26).
