Article Synopsis
  • Aspirin can help reduce preeclampsia risk in singleton pregnancies, but there's ongoing debate over the best dosage due to a lack of studies comparing lower (75-81 mg) and higher (160 mg) doses.
  • This study aimed to evaluate how different doses of aspirin affect the prevention of preeclampsia and other hypertensive disorders specifically in twin pregnancies.
  • Conducted as a multicentre retrospective cohort study in Europe, the research involved grouping twin pregnancies into no aspirin, 80-100 mg, and 160 mg doses, analyzing their outcomes through statistical methods like propensity score matching and Cox regression.

Article Synopsis
  • The study investigates how much fatty acids (FAs) are produced by human fetuses and how this relates to the fatty acids present in their mothers' blood at delivery.
  • Researchers analyzed data from 39 mother-fetus pairs, noting significant correlations in specific fatty acid levels between mothers and fetuses, indicating reliance on maternal sources.
  • Results show that while maternal DHA sources differed (algae vs. fish oil), the fetus contributes little to fatty acid production, highlighting the importance of maternal nutrition during pregnancy for fetal development.

Cytomegalovirus causes the most common congenital infection worldwide. With most infants asymptomatic at birth, the few affected may present with variable clinical scenarios, from isolated hearing loss to severe neurologic impairment. Public health interventions include all actions at the health system, community, and individual levels that aim at reducing the burden of congenital Cytomegalovirus.

Arrhythmogenic cardiomyopathy (AC) is a hereditary cardiac disorder characterized by the gradual replacement of cardiomyocytes with fibrous and adipose tissue, leading to ventricular wall thinning, chamber dilation, arrhythmias, and sudden cardiac death. Despite advances in treatment, disease management remains challenging. Animal models, particularly mice and zebrafish, have become invaluable tools for understanding AC's pathophysiology and testing potential therapies.

We analyzed and compared variations in the urinary metabolome, as well as postnatal clinical outcomes among preterm infants, based on the timing of antenatal corticosteroid (ACS) administration in response to preterm labor onset in their mothers. This was a prospective observational study held in the Neonatal Intensive Care Unit, Department of Woman's and Child's Health, Padova University Hospital (Italy). A urine sample was obtained from each patient within 24 h of birth; Mass Spectrometry-based untargeted metabolomics analysis was then conducted.

Background: Preterm birth is a major cause of perinatal morbidity and mortality. It is unclear whether the introduction of a universal transvaginal ultrasound cervical length screening program in women at low risk for preterm delivery is associated with a reduction in the frequency of preterm birth.

Objective: To test the hypothesis that the introduction of a midtrimester universal transvaginal ultrasound cervical length screening program in asymptomatic singleton pregnancies without prior preterm delivery would reduce the rate of preterm birth at <37 weeks of gestation.

Article Synopsis
  • Increased research on SARS-CoV-2 infection during pregnancy shows mixed-quality studies lead to ongoing debate about risks.
  • A meta-analysis including 137 studies found that pregnant women with SARS-CoV-2 face significantly higher risks for maternal mortality, ICU admission, and other severe complications compared to uninfected counterparts.
  • Neonates born to these infected women are more likely to experience issues like preterm birth and low birth weight, although no link to stillbirth was established.

Background: The biochemical variations occurring in intrauterine growth restriction (IUGR), when a fetus is unable to achieve its genetically determined potential, are not fully understood. The aim of this study is to compare the urinary metabolomic profile between IUGR and non-IUGR very preterm infants to investigate the biochemical adaptations of neonates affected by early-onset-restricted intrauterine growth.

Methods: Neonates born <32 weeks of gestation admitted to neonatal intensive care unit (NICU) were enrolled in this prospective matched case-control study.

Foetal Growth Restriction (FGR), previously known as Intrauterine Growth Restriction (IUGR), is an obstetrical condition due to placental insufficiency, affecting yearly about 30 million newborns worldwide. In this work, we aimed to identify and pharmacologically target signalling pathways specifically involved in the FGR condition, focusing on FGR-related cardiovascular phenotypes. The transcriptional profile of human umbilical cords from FGR and control cases was compared with the response to hypoxia of zebrafish () transgenic lines reporting the activity of twelve signalling pathways involved in embryonic development.

Article Synopsis
  • Antenatal factors contribute to the development of necrotizing enterocolitis (NEC) in fetuses with growth restriction.
  • This study examined the effectiveness of fetal ductus venosus Doppler (DV) and other metrics like IG21 and Fenton curves in predicting NEC among these fetuses over a decade at a single center.
  • Key findings indicated that specific Doppler characteristics, such as absent or reversed end-diastolic flow, along with a lower Fenton z-score, were associated with NEC, and a predictive model combining these factors achieved an impressive accuracy of 84%.

We urgently need answers to basic epidemiological questions regarding SARS-CoV-2 infection in pregnant and postpartum women and its effect on their newborns. While many national registries, health facilities, and research groups are collecting relevant data, we need a collaborative and methodologically rigorous approach to better combine these data and address knowledge gaps, especially those related to rare outcomes. We propose that using a sequential, prospective meta-analysis (PMA) is the best approach to generate data for policy- and practice-oriented guidelines.

The prenatal environment is of fundamental importance for the fetus, as the fetus is particularly susceptible to environmental influences while in utero, and several prenatal adversities may constitute a risk factor for fetal growth and child development. Intrauterine growth restriction (IUGR) refers to a pregnancy complication involving the inadequate growth of the fetus in utero, with potential programming consequences on the children's brain-behavior development. In this narrative review we will discuss the most recent literature about IUGR children, including their development and their relationship with the prenatal and postnatal environment.

The importance of DHA to support fetal development and maternal health is well established. In this study, we applied the natural abundance approach to determine the contribution of 200 mg/d of DHA supplement to the plasma DHA pool in nineteen healthy pregnant women. Women received DHA, from week 20 until delivery, from an algal source ( 13, Algae group) or from fish oil ( 6, Fish group) with slightly different content of C.

Objective: Our aim was to assess diagnostic accuracy in the prediction of small for gestational age (SGA <10th centile) and fetal growth restricted (FGR) (SGA <3rd centile) fetuses using three different sonographic methods in pregnancies at increased risk of fetal growth restriction: 1) fetal abdominal circumference (AC) z-scores, 2) estimated fetal weight (EFW) z-scores according to postnatal reference standard; 3) EFW z-scores according to a prenatal reference standard.

Methods: Singleton pregnancies at increased risk of fetal growth restriction seen in two university hospitals between 2014 and 2015 were studied retrospectively. EFW was calculated using formulas proposed by the INTERGROWTH-21st project and Hadlock; data derived from publications by the INTEGROWTH-twenty-first century project and Hadlock were used to calculate z-scores (AC and EFW).
