Maternal and perinatal outcomes related to COVID-19 and pregnancy: An overview of systematic reviews.

Introduction: Evidence about coronavirus disease 2019 (COVID-19) and pregnancy has rapidly increased since December 2019, making it difficult to make rigorous evidence-based decisions. The objective of this overview of systematic reviews is to conduct a comprehensive analysis of the current evidence on prognosis of COVID-19 in pregnant women.

Material And Methods: We used the Living OVerview of Evidence (L·OVE) platform for COVID-19, which continually retrieves studies from 46 data sources (including PubMed/MEDLINE, Embase, other electronic databases, clinical trials registries, and preprint repositories, among other sources relevant to COVID-19), mapping them into PICO (population, intervention, control, and outcomes) questions.

Corpus callosum differences assessed by fetal MRI in late-onset intrauterine growth restriction and its association with neurobehavior.

Objective: The aim of this study is to evaluate corpus callosum (CC) development by Magnetic Resonance Imaging (MRI) in late-onset intrauterine growth restricted (IUGR) fetuses compared to appropriate for gestational age and its association with neurobehavioral outcome.

Method: One hundred and seventeen late-onset IUGR and 73 control fetuses were imaged using a 3T MRI scanner at term, obtaining T2 half-Fourier acquisition single-shot turbo spin-echo anatomical slices. CC length, thickness, total area and the areas after a subdivision in 7 portions were assessed.
