INTRODUCTION: We evaluated the utility of placental volume and three-dimensional (3D) vascular flow indices to predict early and late preeclampsia. MATERIAL AND METHODS: In 1,004 pregnancies attending routine care, we recorded first-trimester screening program for aneuploidy (FTSA) parameter and measured uterine artery pulsatility index (uterine-a PI). Placental volume and vascular flow indices were obtained using 3D power Doppler and VOCAL techniques. RESULTS: Placental volume was lower and uterine-a PI was higher in both early and late preeclampsia groups versus nonaffected pregnancies...

BACKGROUND: A midtrimester cervical length (CL) <25 mm is associated with spontaneous preterm birth (sPTB). However, as CL ≥25 mm is not enough to exclude recurrence in high-risk patients, follow-up CL measurement later in pregnancy has been proposed. OBJECTIVES: To evaluate whether CL measurement at 26±1 weeks in asymptomatic high-risk patients improves the prediction of sPTB recurrence. METHODS: A retrospective cohort of high-risk women because of previous sPTB was analyzed...

Spontaneous preterm birth has enormous consequences for newborns, children, and families. Intra-amniotic inflammation (IAI) is the leading cause of spontaneous preterm delivery, mainly at earlier gestational ages. Amniocentesis is the only method used to identify IAI in clinical practice. Although it is an invasive procedure with a very low risk of complications, many women and physicians are hesitant about amniocentesis on this indication. This has been an incentive to explore IAI and the intra-amniotic environment through noninvasive techniques, such as sampling cervical mucus, vaginal fluid, or maternal blood...

BACKGROUND: The diagnostic assessment of fetal arrhythmias relies on the measurements of atrioventricular (AV) and ventriculoatrial (VA) time intervals. Pulsed Doppler over in- and outflow of the left ventricle and tissue Doppler imaging are well-described methods, while Doppler measurements between the left brachiocephalic vein and the aortic arch are less investigated. The aim of this study was to compare these methods of measurement, to find influencing factors on AV and VA times and their ratio, and to create reference ranges...

INTRODUCTION: The structural correspondence of neurodevelopmental impairments related to intrauterine growth restriction (IUGR) that persists later in life remains elusive. Moreover, early postnatal stimulation strategies have been proposed to mitigate these effects. Long-term brain connectivity abnormalities in an IUGR rabbit model and the effects of early postnatal environmental enrichment (EE) were explored. MATERIALS AND METHODS: IUGR was surgically induced in one horn, whereas the contralateral one produced the controls...

INTRODUCTION: Fetuses who fail to reach their genetic growth potential are thought to have sub-optimal placental function. Low placental growth factor (PlGF) levels have been shown to be predictive of placentally mediated conditions, such as pre-eclampsia or fetal growth restriction. We investigated the screening performance of PlGF for the prediction of low birth weight (<10th centile for gestation) and adverse intrapartum and neonatal outcomes in apparently low-risk term pregnancies...
