UOG retains its position as third out of 83 journals in the field of Obstetrics and Gynecology, with an impressive Impact Factor of 5.6. UOG Editor-in-Chief Prof. Anthony Odibo states: “the continued success of Ultrasound in Obstetrics & Gynecology is attributable to the loyalty of our authors, whose high-quality and clinically relevant material we publish, and to the hard work of our editors and reviewers, who improve the work that is submitted. The UOG team would like to thank wholeheartedly the many contributors who have helped to sustain our impressive ranking.”

Since the introduction of ultrasound in the field of urogynecology, its applications have expanded from being focused on evaluation of the bladder and bladder neck to including assessment of obstetric anal sphincter injuries, pelvic organ prolapse, morphological abnormalities of the levator ani and vaginal wall mesh implants. This new Virtual Issue from Ultrasound in Obstetrics & Gynecology presents a selection of recent papers reporting on these topics, including on the use of 3D and 4D ultrasound and pregnancy-related changes in the pelvic floor musculature. These papers are FREE to read for a limited period.

“Although the main cause of fetal megacystis is LUTO, an enlarged fetal bladder can also be present as a concomitant finding of miscellaneous genetic syndromes, developmental disturbances and chromosomal abnormalities" finds new Original Paper by Fontanella and colleagues in the June issue of the UOG Journal.

The performance of cfDNA testing for trisomy 21 in twin pregnancy is similar to that reported in singleton pregnancy and is superior to that of the first-trimester combined test or second-trimester biochemical testing.

The procedure-related risk of miscarriage following chorionic villus sampling or amniocentesis is lower than currently advocated and negligible when compared with controls of similar risk profile, finds free access UOG Journal updated meta-analysis by Salomon et al.

“There is considerable methodological heterogeneity in studies reporting reference ranges for umbilical and middle cerebral artery Doppler indices and cerebroplacental ratio, and the resulting references have important implications for clinical practice” finds new free-access UOG Journal systematic review by Oros and colleagues.

Persistence of hindbrain herniation on MRI 6 weeks after prenatal myelomeningocele repair independently predicted the need for postnatal hydrocephalus treatment better than any ultrasound‐ or other MRI‐derived measurements of ventricular characteristics, finds new free-access UOG Journal study by Zarutskie and colleagues.

The incidence of twin pregnancy is rising, due mainly to advanced maternal age and resultant widespread use of assisted reproductive techniques. It is associated with a high risk of perinatal mortality and morbidity, particularly in monochorionic pregnancy, with complications such as selective fetal growth restriction and twin–twin transfusion syndrome contributing to this risk. This new Virtual Issue from Ultrasound in Obstetrics & Gynecology presents a selection of recent papers reporting on screening, management and prevention of preterm birth in twin pregnancy. These papers are FREE to read for a limited period.

This score showed good discriminative capacity in predicting LUTO, and better diagnostic accuracy compared with that of the classic ultrasound triad of megacystis, keyhole sign and hydronephrosis.

“Sonographic assessment of fetal head position prior to vacuum extraction did not show any benefit in terms of reduced risk of failed instrumental delivery or maternal and fetal morbidity” shows a prematurely discontinued UOG Journal randomized controlled trial by Ghi and colleagues.

The July issue of Ultrasound in Obstetrics & Gynecology is out now. This issue has a special focus on fetal weight, with relevant articles on the accuracy of estimated fetal weight formulae, a new birth-weight reference chart that includes fetuses still in utero, and the screening and management of small-for-gestational-age fetuses.
