OBJECTIVES: The availability of cell-free DNA (cfDNA) as a screening tool affords an opportunity for non-invasive identification of sex chromosome aneuploidies (SCAs). This longitudinal study from 1995 through 2021 investigates both the evolution and frequency of prenatal diagnostic testing using amniocentesis (AF) and chorionic villus sampling (CV), and the detection of SCAs through cfDNA samples from a large cohort in Northern Italy. METHODS: The results of genetic testing from CV and AF samples collected from public and private centers in Italy from 1995 to 2021 were collected...

OBJECTIVE: Two-dimensional (2D) transvaginal ultrasound (TVS) is an accessible and cost-effective diagnostic tool in the detection of adenomyosis. Different ultrasound features related to adenomyosis have been described, but the predictive value of each ultrasound sign and their combination requires further investigation. We analyzed the accuracy of 2D-TVS and describe possible combinations of ultrasound signs with a high predictive value in the diagnosis of adenomyosis. METHODS: This study has been conducted as a prospective multicenter trial including nine expert centers specialized in diagnosis and treatment of endometriosis...

OBJECTIVE: The prediction of adverse perinatal outcomes in low-risk pregnancies is poor, mainly due to the lack of reliable biomarkers. Uterine artery Doppler is closely associated with placental function and could assist in the peripartum detection of subclinical placental insufficiency. The objective of this study was to evaluate the relationship between mean uterine artery pulsatility index (PI) measured in early labor with obstetric intervention for suspected intrapartum fetal compromise and adverse perinatal outcomes in uncomplicated singleton term pregnancies...

OBJECTIVES: The aims of this study were to evaluate the prenatal ultrasound features associated with operative complications and to assess the interobserver agreement in a cohort with detailed intraoperative and histopathologic data. METHODS: We conducted a retrospective, multicentre cohort study of 102 patients at high-risk of placenta accreta spectrum (PAS) between January 2019 and May 2022. De-identified ultrasound images were reviewed retrospectively and independently by two experienced operators blinded to clinical details, intra-operative features, outcome, and the histopathologic findings...

OBJECTIVES: The objective of this study is to compare short-term variation (STV) outputs from a novel self-applied non-invasive fetal electrography (NIFECG) with hospital computerized cardiotocography (cCTG) monitors. Technological and algorithmic limitations, as well as mitigation strategies will be evaluated. METHODS: This prospective cohort study took place in a tertiary London hospital. Women with a singleton pregnancy over 28+0 weeks' gestation attending hospital for cCTG assessment were monitored with both NIFECG and cCTG simultaneously for up to one hour...

OBJECTIVES: International guidelines recommend delivery from 37 weeks in small for gestational age (SGA) fetuses mostly because of stillbirth concerns. Differentiating SGA from late-onset fetal growth restriction (FGR) is challenged by the limited prospective evidence to guide management. We prospectively assessed a novel protocol that used ultrasound criteria to classify women with suspected late FGR into two groups: low-risk with expectant management until the expected date of delivery and high-risk with delivery soon after 37 weeks...

OBJECTIVE: To establish the correlation of phase-rectified signal averaging (PRSA) outputs between a novel self-applicable non-invasive fetal electrocardiography (NIFECG) monitor, and the computerized cardiotocograph (cCTG). A secondary objective is to evaluate the potential for assessing fetal wellbeing in the remote setting by assessing the relationship PRSA to short-term variation (STV). METHODS: This was a prospective observational study carried out in a London teaching hospital...

OBJECTIVE: Ventriculomegaly can be associated with long-term neurodevelopmental impairment. The prenatal diagnosis of ventriculomegaly is most often made at the routine second trimester anomaly scan. The value of first trimester ultrasound has expanded to early diagnosis and screening of fetal abnormalities. The objective of this study was to assess the predictive accuracy of first trimester choroid plexus to head/ventricle ratios for development of ventriculomegaly at a later gestation...

OBJECTIVE: Having adequate reference ranges of the size of corpus callosum (CC) is necessary to better characterize CC abnormalities and improve parental counseling. The objective of this study was to evaluate the methodology used in developing different references charts for CC biometry. METHODS: We conducted a systematic review of studies of fetal CC biometry using a set of predefined quality criteria of study design, statistical analysis and reporting methods...

OBJECTIVES: This study aimed to evaluate the prenatal characteristics of double aortic arch (DAA), assess the relative size of the arches and their growth during pregnancy, describe associated cardiac, extracardiac and chromosomal/genetic abnormalities and review postnatal presentation and clinical outcome. METHODS: All fetuses with a confirmed diagnosis of DAA seen in five specialized referral centers between November 2012 and November 2019 were retrospectively identified from the hospitals' fetal databases...

OBJECTIVE: Twin pregnancies are at high risk of preterm birth, especially when complicated by twin-twin transfusion syndrome (TTTS). Transvaginal ultrasound (TVUS) measurement of cervical length (CL) is one of the most powerful predictors of preterm birth. Cervical length may also be measured by MRI, but its predictive accuracy for PTB has not been well established. Pregnancies with TTTS that are candidates for selective fetoscopic laser photocoagulation (SFLP) at our institution undergo TVUS and MRI evaluation of cervical length to assess preterm birth risk during the perioperative period...

OBJECTIVES: To investigate the predictive performance of the Fetal Medicine Foundation (FMF) first trimester screening algorithm for pre-eclampsia in a Danish population and compare screening performance with the current Danish strategy, which is based on maternal risk factors. METHODS: Women with singleton pregnancies, attending for their first trimester ultrasound scan and screening for aneuploidies, were included at six Danish university hospitals between May 2019 and December 2020...

OBJECTIVE: To assess the frequency of genetic syndromes and childhood neurodevelopmental impairment in non-malformed term infants with severely low birthweight and no evidence of placental insufficiency. METHODS: This case series was constructed of infants delivered at term between 2013 and 2018 with severely low birthweight defined as below -2.5 SD, with normal maternal and fetal Doppler studies (umbilical artery, fetal middle cerebral artery, cerebroplacental ratio, and uterine artery) and no hypertensive disorders during pregnancy or structural anomalies at prenatal ultrasound examination...

OBJECTIVE: Obesity and pre-eclampsia (PE) both relate to vascular dysfunction, which translates into an increased risk for cardiovascular disease later in life. The aim of this study was to determine if BMI and history of PE interacted with one and another in their effects on vascular health. METHODS: In an observational case-control study 30 women with a history of PE were compared with 31 age- and BMI-matched controls after an uncomplicated pregnancy. Six to twelve months post-partum flow-mediated dilation (FMD), carotid intima media thickness (cIMT) and carotid distensibility (CD) were measured...
