Our new podcast episode features Dr Roberto Romero and Prof. Fabricio Da Silva Costa.

This month’s open chapter is on twin pregnancy, also known as monoamniotic pregnancies. A twin pregnancy is defined as “monoamniotic” in the presence of a single placenta with one amnion and one chorion.

The October issue of Ultrasound in Obstetrics and Gynecology includes a systematic review on the timing of induction of labor in suspected macrosomia, a randomized controlled trial on improving the performance of inexperienced ultrasound operators using an artificial intelligence training system, a nationwide cohort study on the use of combined first-trimester screening and invasive diagnostics for detection of atypical chromosomal aberrations and a study assessing the impact of uterine fibroids on non-informative cell-free DNA screening results.

The September issue of Ultrasound in Obstetrics & Gynecology includes a systematic review on maternal prepregnancy weight as an independent risk factor for congenital heart defect, a prospective study of cardiovascular adaptation in women with previous pregnancy complicated by a hypertensive disorder, an analysis of the discriminative performance of the ADNEX model and IOTA two-step strategy for adnexal masses in a low-risk population and a study assessing postnatal outcome following fetal aortic valvuloplasty for critical aortic stenosis.

This month’s VISUOG chapter focuses on cervical ectopic pregnancy. Cervical pregnancy is an uncommon form of ectopic pregnancy where the pregnancy implants into the myometrium below the level of the internal os. It accounts for less than 1% of all ectopic pregnancies, occurring in approximately 1 in 9000 pregnancies.

The June issue of Ultrasound in Obstetrics & Gynecology includes a systematic review on the trimester-specific diagnostic performance of ultrasound in placenta accreta spectrum, a neuroimaging study investigating brain injury in pregnancies with twin–twin transfusion syndrome, a longitudinal evaluation of cervical stiffness in women who undergo spontaneous preterm delivery and a study comparing the characteristics of ovarian and tubal ectopic pregnancies.

The April issue of Ultrasound in Obstetrics & Gynecology includes a systematic review on the diagnostic performance of prenatal ultrasound in coarctation of the aorta, a nationwide cohort study on the outcome of multifetal reduction in quadruplet pregnancy, a study validating the IETA-1 model for intracavitary uterine pathology in women without abnormal uterine bleeding and a summary of the findings of a systematic review on cervical cerclage in twin pregnancy.

The February issue of Ultrasound in Obstetrics & Gynecology includes a systematic review evaluating adverse perinatal outcome in dichorionic twin pregnancy complicated by selective fetal growth restriction, a study deriving chorionicity-specific reference ranges for fetal growth in twin pregnancy, an analysis of emergency Cesarean delivery in placenta previa and placenta accreta spectrum and an evaluation of the diagnostic test accuracy of a standardized transvaginal examination for deep endometriosis of the uterosacral ligaments and torus uterinus.

Read the new ISUOG Practice Guidelines on the performance of third-trimester obstetric ultrasound scan.

The January issue of Ultrasound in Obstetrics & Gynecology includes a systematic review exploring the value of whole-genome sequencing in the diagnosis of congenital anomalies, a randomized controlled trial investigating the utility of visual biofeedback during the second stage of labor in facilitating maternal pushing, a study on the diagnosis of superficial endometriosis using transvaginal ultrasound, and a study demonstrating the potential of deep learning in improving fetal heart screening. This issue also features the new ISUOG Practice Guidelines on the performance of third-trimester obstetric ultrasound scan.

VISUOG is a comprehensive visual encyclopedia for ultrasound in obstetrics & gynecology. Detailed anatomical visualisations, case studies and expert commentary have collectively contributed to enhancing clinical decision-making and diagnostic accuracy.

The December issue of Ultrasound in Obstetrics & Gynecology includes a systematic review collating the current evidence on prenatal diagnosis and perinatal outcome of congenital knee dislocation, a multicenter study proposing a new model for prediction of adverse outcome in extremely preterm growth-restricted fetuses requiring early delivery, a large regional study evaluating the role of SARS-CoV-2 infection as a cause of fetal death, a study assessing the impact of choroid plexus size in cases with an abnormal closure of the fourth ventricle, and a prospective study demonstrating the potential of photoacoustic imaging in improving O-RADS risk assessment of adnexal lesions. Also in the issue, we celebrate the award winners announced at the 33rd World Congress on Ultrasound in Obstetrics and Gynecology and thank all contributors to the Journal’s peer-review process in 2023.

Post-cesarean delivery niche: treatment and prevention of CSP. Co-chaired by Prof. Ilan E. Timor-Tritsch and Prof. Simon Meagher. Livestreaming: Sunday, 21 January 2024, 12:00 – 19:00 (GMT)

According to the World Health Organization (WHO), an estimated 13 million babies are born prematurely every year. That’s roughly 25 preterm babies every minute – around the world.  

The November issue of Ultrasound in Obstetrics & Gynecology includes a systematic review evaluating the incidence of urological complications in women undergoing Cesarean section for placenta accreta spectrum disorders, a study proposing a new marker to facilitate identification of fetuses with agenesis of the corpus callosum, and two studies providing evidence of an association between epidural analgesia and increased risk of emergency delivery for fetal compromise. The potentially significant impact of the findings of the latter two studies are countered in an accompanying Editorial by Cavoretto and colleagues and in a series of Correspondence articles.

The October issue of Ultrasound in Obstetrics & Gynecology includes a systematic review evaluating the incidence and predictive factors of obstetric anal sphincter injury in primiparous women, a study providing preliminary evidence supporting the feasibility and efficacy of prenatal open spina bifida repair in twin pregnancy and two studies assessing the utility of glycosylated fibronectin as a new biomarker for pre-eclampsia screening in mixed and Asian populations. The issue also features a study demonstrating the efficacy and safety of in-utero treatment of sustained fetal supraventricular arrhythmia in late preterm and term fetuses and an accompanying Editorial on the topic.

The September issue of Ultrasound in Obstetrics & Gynecology includes a systematic review examining the impact of concurrent selective fetal growth restriction on the outcome of pregnancies with twin–twin transfusion syndrome following laser surgery, a study investigating the prevalence, pathophysiology and impact of a midline cystic structure recently reported in some fetuses with open spina bifida, a prospective study aiming to determine the best strategy for prediction of hypertensive disorders at 36 weeks’ gestation, and a large study of 25,329 patients evaluating the effect of reproductive history on the outcome of in-vitro fertilization.

The June issue of Ultrasound in Obstetrics & Gynecology includes a prospective study investigating the applicability of the Fetal Medicine Foundation screening algorithm to pre-eclampsia screening in Denmark, a study evaluating the clinical value of expanded non-invasive prenatal screening compared with chromosomal microarray analysis, a systematic review examining the impact of fetal endoscopic tracheal occlusion in cases with congenital diaphragmatic hernia according to disease severity, and a study comparing the outcome following selective termination of the presenting twin vs non-presenting twin. This issue also includes the newly updated ISUOG Practice Guideline on the performance of fetal cardiac screening.

The April issue of Ultrasound in Obstetrics & Gynecology includes a systematic review evaluating the safety and effectiveness of prenatal valacyclovir therapy in prevention and treatment of congenital cytomegalovirus infection, a large population-based study investigating the link between birth-weight centile and school performance, a prospective longitudinal study providing reference ranges for uterine artery pulsatility index across gestation and a Delphi consensus study focusing on ultrasound in the prenatal evaluation and management of patients at high risk of placenta accreta spectrum at delivery.
