Review Meta AnalysisImpact of low-dose aspirin on adverse perinatal outcome: meta-analysis and meta-regression.
To perform a meta-analysis and meta-regression of randomized controlled trials (RCTs) to evaluate the impact of low-dose aspirin (LDA) on perinatal outcome, independent of its effect on pre-eclampsia (PE), preterm birth and low birth weight. ⋯ LDA improves some important perinatal outcomes, without increasing adverse events such as placental abruption or periventricular hemorrhage, and its utility, if commenced prior to 16 weeks' gestation, may be considered in a wider context beyond the prevention of PE or fetal growth restriction.

Meta AnalysisOutcome of non-visualization of fetal gallbladder on second-trimester ultrasound: cohort study and systematic review of literature.
To investigate the ultrasound characteristics and outcome of fetuses with non-visualization of the fetal gallbladder (NVFGB) followed in our tertiary university hospital, and to provide a comprehensive review of the literature on prenatal findings and outcome of NVFGB. ⋯ In cases with persistent NVFGB, the risk of a severe postnatal condition should be considered. A detailed ultrasound scan should be offered and parents tested for cystic fibrosis gene mutation. An invasive procedure for karyotyping and measurement of liver enzyme concentrations before 22 weeks constitutes a reasonable work-up. Copyright © 2019 ISUOG. Published by John Wiley & Sons Ltd.

Meta Analysis Comparative StudyRole of magnetic resonance imaging in fetuses with mild or moderate ventriculomegaly in the era of fetal neurosonography: systematic review and meta-analysis.
To report the rate of additional central nervous system (CNS) anomalies detected exclusively on prenatal magnetic resonance imaging (MRI) in fetuses diagnosed with isolated mild or moderate ventriculomegaly (VM) on ultrasound, according to the type of ultrasound protocol adopted (dedicated neurosonography vs standard assessment of the fetal brain), and to explore whether the diagnostic performance of fetal MRI in detecting such anomalies is affected by gestational age at examination and laterality and degree of ventricular dilatation. ⋯ In fetuses undergoing dedicated neurosonography, the rate of a CNS anomaly detected exclusively on MRI is lower than that reported previously. Early MRI has an excellent diagnostic performance in identifying additional CNS anomalies, although the findings from this review suggest that MRI performed in the third trimester may be associated with a better detection rate for some types of anomaly, such as cortical, white matter and intracranial hemorrhagic anomalies.

Meta AnalysisDiagnostic accuracy of saline contrast sonohysterography in detecting endometrial polyps in women with postmenopausal bleeding: systematic review and meta-analysis.
In women with postmenopausal bleeding, endometrial polyps are a frequent finding and the risk of a focal (pre)malignancy in a polyp is up to 6%. Because of this reported risk, the detection of polyps in these women, preferably by a minimally invasive method, is important. The aim of this systematic review was to assess the accuracy of saline contrast sonohysterography (SCSH) for diagnosis of endometrial polyps in women with postmenopausal bleeding. ⋯ Provided that the SCSH examination is of optimal quality, it can be considered as a method to stratify women with postmenopausal bleeding for further diagnostic workup and treatment with hysteroscopy. In women without suspicion of a polypoid lesion on SCSH, and with a benign endometrial sample, expectant management should be considered. Copyright © 2019 ISUOG. Published by John Wiley & Sons Ltd.

Meta AnalysisPerinatal outcome of monochorionic twin pregnancy complicated by selective fetal growth restriction according to management: systematic review and meta-analysis.
To explore the impact of severity and management (expectant, laser treatment or selective reduction) on perinatal outcome of monochorionic twin pregnancies complicated by selective fetal growth restriction (sFGR). ⋯ Type-I sFGR is characterized by good perinatal outcome when managed expectantly, which represents the most reasonable management strategy for the large majority of affected cases. Pregnancies complicated by Type-II or -III sFGR treated with fetoscopic laser ablation have a higher rate of mortality but lower rate of morbidity compared with those managed expectantly, supporting the use of fetal therapy at gestations remote from neonatal viability. Data on outcome following selective reduction are scarce. In view of the lack of evidence from randomized controlled trials, prenatal management of sFGR should be individualized according to gestational age at diagnosis, severity of growth discordance and magnitude of Doppler anomalies.
