The August issue of Ultrasound in Obstetrics & Gynecology includes a systematic review of studies developing reference charts for fetal biometry of the corpus callosum, a large study investigating the implication of third-trimester screening accuracy for small-for-gestational age and additive value of third-trimester growth-trajectory indicators in predicting severe adverse perinatal outcome in low-risk pregnancies, a study on diagnostic sonographic features and management of intramural pregnancy, and a study proposing markers for first-trimester prediction of ventriculomegaly.

The July issue of Ultrasound in Obstetrics & Gynecology includes a systematic review investigating the prevalence of adenomyosis in women with subfertility, a review focusing on the definition of the uterine junctional zone and its appearance in adenomyosis, a study proposing sonographic descriptors for instant diagnosis of 20 major fetal anomalies and a population-level study evaluating the incidence, risk factors and timing of pregnancy loss in major congenital heart disease.

The May issue of Ultrasound in Obstetrics & Gynecology includes a systematic review investigating the outcome following early vs late selective termination in dichorionic twin pregnancies, a prospective study aiming to estimate the prevalence of endometriosis using transvaginal ultrasound, a study proposing new criteria for predicting outcome in cases of tricuspid valve dysplasia and Ebstein’s anomaly using fetal tricuspid regurgitation waveform analysis, and a large prospective midgestation study examining cardiac function and morphology of fetuses conceived via in-vitro fertilization. The May issue also features a randomized controlled trial evaluating the impact of predictive information regarding the likely outcome of pregnancy on psychological wellbeing of women with a pregnancy of uncertain viability during the waiting period to final diagnosis.

The January issue of Ultrasound in Obstetrics & Gynecology includes a systematic review and meta-analysis investigating perinatal outcome following blastocyst- vs cleavage-stage embryo transfer, two multicenter studies on cytomegalovirus infection in pregnancy, and a follow-up study of a multicenter trial, which is the first to report on the long-term mortality and morbidity of cases receiving transplacental treatment for fetal supraventricular tachyarrhythmia. This issue also includes the newly updated ISUOG Practice Guideline on the performance of first-trimester ultrasound scan.

The July issue of Ultrasound in Obstetrics & Gynecology includes a systematic review and meta-analysis evaluating perinatal outcome of triplet pregnancies following fetoscopic laser surgery for twin–twin transfusion syndrome, a new study exploring the role of ophthalmic artery Doppler in the prediction of pregnancy complications, a prospective study comparing fetal growth in IVF/ICSI pregnancies following frozen–thawed vs fresh blastocyst transfer and a Delphi study providing revised definitions of the MUSA features of adenomyosis.
