The December issue of Ultrasound in Obstetrics & Gynecology includes an article outlining the top 10 global research priorities for multiple pregnancy, a systematic review on the performance of middle cerebral artery peak systolic velocity for the prediction of anemia in transfused and untransfused fetuses, a study describing a new first-trimester sonographic marker of spina bifida, and a study on the impact of three definitions of septate uterus. Also out this month is a new video abstract accompanying a randomized controlled trial of elective delivery vs routine obstetric care in fetal gastroschisis.

Desorden en el neurodesarrollo en niños que se creen tener prenatalmente ventriculomegalia leve aislada

The August issue of Ultrasound in Obstetrics & Gynecology includes a series of papers on different aspects of fetal brain imaging, including studies on neurodevelopmental outcome and the role of magnetic resonance imaging in fetal isolated mild ventriculomegaly, and the sonographic assessment of the Slyvian fissures and their development in fetuses with cortical maldevelopment. Articles on other topics include a systematic review, with an accompanying video abstract, on the effectiveness on fertility outcome of tubal flushing using different contrast media, and a study on core principles for parental engagement in the perinatal mortality review process.
