Article Synopsis
  • A study in the Netherlands evaluated the effectiveness of first-trimester anomaly scans to detect fetal structural defects in pregnant women as part of a nationwide prenatal screening program from November 2021 to November 2022.
  • The study found that 74.9% of eligible women opted for the scan, and among those, 1.0% were flagged for potential anomalies while 54.9% of those cases were confirmed with abnormal findings in follow-up scans.
  • The results highlighted the types of anomalies identified, including 332 structural and 117 genetic anomalies, indicating the scan's usefulness for early decision-making regarding reproductive options.

Introduction: The aim of this study was to use computerized analysis of the grayscale spectrum (histogram) to provide an objective assessment of the echogenicity of the fetal bowel. Moreover, we investigated the role of histogram analysis in the prenatal prediction of postnatal outcomes in fetuses with echogenic bowel (fetal echogenic bowel [FEB]).

Methods: This is a single-center retrospective study including all fetuses with a diagnosis of echogenic bowel (FEB) in the mid-second trimester between 2015 and 2021.

Article Synopsis
  • The study evaluates a quality control system for first-trimester anatomical screening (FTAS) ultrasound exams and the learning curves of sonographers involved in these screenings.
  • Conducted between 2012 and 2015 in North-Netherlands, researchers analyzed logbook images from six sonographers, focusing on their ability to visualize 12 specific anatomical planes.
  • Results showed that only 57% of logbooks met the sufficient score criteria, with the highest visualization success for the fetal skull and brain, while the lowest scores were for the face and spine, indicating areas where sonographers need improvement.

Objective: We aimed to evaluate the additional value of advanced fetal anatomical assessment by ultrasound in pregnancies with twice inconclusive noninvasive testing (NIPT) due to low fetal fraction (FF).

Methods: We performed a multicenter-retrospective study between 2017 and 2020 including 311 pregnancies with twice inconclusive NIPT due to low FF ≤ 1%. Women were offered invasive testing and advanced fetal anatomical assessment at ≤18 weeks' gestation.

Introduction: Since 2021, first-trimester anatomical screening (FTAS) is offered in the Netherlands alongside genome-wide cell-free DNA (cfDNA). Previously, only second-trimester anatomical screening (STAS) was offered. This study identifies structural abnormalities amenable to first-trimester diagnosis detected at/after STAS in the period following cfDNA implementation and preceding FTAS introduction.

Background: Prenatal diagnosis of several major congenital anomalies can be achieved in the first trimester of pregnancy.

Objective: This study investigates the timing of diagnosis and pregnancy outcome of foetuses and neonates with selected structural anomalies in the Northern Netherlands over a 10-year period when the prenatal screening programme changed significantly, but no first-trimester anatomical screening was implemented.

Methods: We performed a population-based retrospective cohort study with data from the EUROCAT Northern Netherlands database on pregnancies with delivery or termination of pregnancy for fetal anomaly (TOPFA) date between 2010 and 2019.

Sildenafil is under investigation as a potential agent to improve uteroplacental perfusion in fetal growth restriction (FGR). However, the STRIDER RCT was halted after interim analysis due to futility and higher rates of persistent pulmonary hypertension and mortality in sildenafil-exposed neonates. This hypothesis-generating study within the Dutch STRIDER trial sought to understand what happened to these neonates by studying their regional tissue oxygen saturation (rSO) within the first 72 h after birth.

Article Synopsis
  • Severe fetal growth restriction due to placental dysfunction is linked to high rates of perinatal death and health issues in newborns; sildenafil, a phosphodiesterase 5 inhibitor, may improve outcomes by enhancing blood flow in the placenta.
  • A randomized clinical trial in the Netherlands studied whether sildenafil reduces perinatal mortality or severe morbidity in pregnant women with growth-restricted fetuses but was stopped early due to safety concerns, with no clear benefits identified.
  • Out of 360 expected participants, 216 women were enrolled, with patients receiving either sildenafil or a placebo during the trial, aiming to assess the primary outcome of perinatal mortality or major neonatal issues until hospital discharge.

Purpose:  To investigate hemodynamic effects after antenatal corticosteroids (ACS) administration in appropriate for gestational age (AGA) and early growth restricted (GR) fetuses by measurement of Doppler cardiovascular function parameters.

Materials And Methods:  Prospective cohort study. AGA and GR singleton pregnancies receiving ACS for fetal lung maturation between 24 + 0-33 + 6 weeks were enrolled.

Objective: Preeclampsia is associated with profound vasoconstriction in most organ systems and reduced plasma volume. Because water immersion produces a marked central redistribution of blood volume and suppresses the renin-angiotensin system response and sympathetic activity, we hypothesized that water immersion might be useful in the treatment of preeclampsia.

Study Design: The effects of thermoneutral water immersion for 3 hours on central and peripheral hemodynamics were evaluated in 7 preeclamptic patients, 7 normal pregnant control patients, and 7 nonpregnant women.

Background: Normal pregnancy is characterized by a decrease in peripheral resistance and generalized vasodilation resulting in plasma volume expansion, which is associated with intrauterine growth. Stiffness of the arterial system may be a measure of the degree of plasma volume expansion. Pulse wave velocity (PWV), measured by applanation tonometry, is a validated approach to determine arterial stiffness.

Objective: The epidemiology of pre-eclampsia suggests a constitutional component for the disorder. We have recently shown an association for blood pressure (BP) with stiffness of joints and skin in adolescents, suggesting that constitutionally determined stiffness of body tissues is associated with blood pressure. Therefore, we compared stiffness of the arterial wall, joints and skin between women with a history of pre-eclampsia and women with an uncomplicated pregnancy.

Background: Preeclampsia is characterized by an increase in peripheral vasoconstriction. Studies of central hemodynamics are limited. Noninvasive evaluation of aortic stiffness and pressure waveform is possible by applanation tonometry.

Objective: Although a large variety of automated blood pressure devices are available, only some have been validated for use in clinical practice. The British Hypertension Society (BHS) recommends separate validation of automated devices in special subgroups, e.g.
