INTRODUCTION: The M6 risk prediction model has been shown to have good triage performance for stratifying women with a PUL as being at low or high-risk of harboring an ectopic pregnancy. There is evidence that M6 has better overall test performance than the hCG ratio (serum hCG at 48 hours/hCG at presentation) and older models such as the M4 model. M6 was published as part of a two-step protocol using an initial progesterone ≤2nmol/l to identify likely failing pregnancies (step 1), followed by M6 (step 2)...

OBJECTIVE: Pregnancies complicated by fetal growth restriction (FGR) have worse outcomes than pregnancies with a small for gestational age (SGA) fetus. There is increasing evidence of a maternal cardiovascular role in the pathophysiology. We aimed to compare the maternal hemodynamic indices (cardiac output and systemic vascular resistance) in pregnancies complicated by FGR and pregnancies with an SGA fetus using a non-invasive device (USCOM-1A®). METHODS: This was a prospective study of normotensive pregnancies complicated by FGR (defined as pregnancies with a birthweight <3rd centile or with Doppler evidence of impaired placental-fetal blood flow), pregnancies with an SGA fetus (defined as pregnancies with a birthweight <10th centile) and control pregnancies (defined as having an appropriately-grown fetus)...

OBJECTIVE: To follow up the noninvasive prenatal testing (NIPT) results of 31515 singleton pregnancies in Fujian province, southeastern China and assess its performance in low-, moderate- and high-risk pregnancies. METHODS: Cell-free plasma DNA was subjected to low-coverage whole-genome sequencing. Standard Z-score analysis of the mapped sequencing reads was used to call fetal aneuploidies, including trisomies 21, 18 and 13 (T21, T18, T13) and sex chromosome aneuploidies (SCAs)...

OBJECTIVES: Early pregnancy loss, also known as miscarriage, is the most frequent complication in first-trimester pregnancy, occurring in 10-15% of all clinically recognized pregnancies. Embryonic numerical and structural chromosomal abnormalities are the most common cause of early pregnancy loss. However, the role of submicroscopic copy number variations (CNVs) in early pregnancy loss is still unclear. Besides, little is known about the critical regions and candidate genes for miscarriage because of the large size of structural chromosomal abnormalities...

BACKGROUND: We have previously proposed that the competing risk model for prediction of preeclampsia (PE) based on maternal characteristics and medical history (prior model), developed in singleton pregnancies, can be extended to risk assessment for twins; in dichorionic (DC) and monochorionic (MC) twin pregnancies with the same characteristics as singleton pregnancies the distribution of gestational age of delivery with PE was shifted to the left by 8 and 10 weeks, respectively. However, in a subsequent validation study we found that in both the training and validation datasets the observed incidence of PE was lower than the predicted one and such overestimation of risk was particularly marked for early-PE...

OBJECTIVES: Infants with congenital diaphragmatic hernia (CDH) are predisposed to pulmonary hypertension after birth, due to lung hypoplasia that impairs fetal pulmonary vascular development. Antenatal sildenafil treatment attenuates abnormal pulmonary vascular and alveolar development in rabbit and rodent CDH models, but whether this translates to functional improvements after birth remains unknown. We aimed to evaluate the effect of antenatal sildenafil on neonatal pulmonary haemodynamics and lung function in lambs with a diaphragmatic hernia (DH)...

BACKGROUND: Antenatal surveillance of intrauterine growth aims to detect growth restricted fetuses who face higher risks of stillbirth. Improving detection could be an effective strategy for stillbirth prevention. The REPERE study was conducted to estimate the association between antenatal detection of small for gestational age (SGA) and stillbirth risk in France. METHODS: REPERE is a case-control study performed in 3 French districts with approximately 30,000 births annually...

OBJECTIVE: To describe umbilical vein (UV) hemodynamic in macrosomic fetuses at 11+0 13+6 weeks of gestation and to build a multiparametric prediction model including pregnancy and ultrasound characteristics able to detect fetal macrosomia in the first trimester. METHODS: Matched case-control study including pregnancies who underwent ultrasound examination at 11+0 to 13+6 weeks for aneuploidy screening at a single centre over a four years period. Cases were women who gave birth a newborn with a BW >90th centile for gestational age and sex according to local birthweight standards, while controls those who delivered newborns with a BW ranging between the 10th and 90th centiles matched by a ratio of 1:3 for maternal age and gestational age...

OBJECTIVE: Pregnancies complicated by late-onset fetal growth restriction (FGR) are at increased risk of short- and long-term morbidities. Despite this, identification of cases at higher risk of adverse perinatal outcome when FGR is diagnosed is challenging. The aims of this study were to elucidate the strength of association and predictive accuracy of maternal and fetal Dopplers in predicting perinatal outcome of fetuses affected by late-onset FGR at the time of diagnosis. METHODS: Prospective study of consecutive singleton pregnancies complicated by late-onset FGR...

Accurate mid-pregnancy prediction of spontaneous preterm birth (sPTB) is essential to ensure appropriate surveillance of high-risk women. Advancing the QUiPP prototype, QUiPP 2 aimed to provide individualised risk of delivery based on cervical length, quantitative fetal fibronectin (qfFN), or both tests combined, taking into account further risk factors, such as multiple pregnancy. Validation of the QUiPP 2 predictive models using a distinct dataset aims to confirm the accuracy and transportability of QUiPP overall and within certain clinically relevant timeframes...
