12/05/2017 - NEW ISUOG Practice Guidelines: performance of fetal MRI
Fetal magnetic resonance imaging (MRI) is an important diagnostic imaging adjunct to ultrasonography, particularly for assessment of the fetal brain. In 2014, fetal MRI was being performed in one or more centers in at least 27 countries worldwide. However, imaging quality, sequences used and operator experience were found to differ widely between centers. To reduce the impact of such differences, the ISUOG Clinical Standards Committee has developed guidelines for performing and interpreting fetal MRI.

10/04/2017 - Blastocyst is not superior to cleavage-stage embryo transfer in assisted reproduction techniques
A new systematic review and meta-analysis by Martins et al. found no difference in reproductive outcomes when comparing blastocyst transfer vs cleavage-stage embryo transfer. Both strategies are acceptable and potential pros/cons should be individualized for each scenario.

26/10/2016 - Majority of stillbirth cases remain unexplained, suggesting post mortem investigation needs to be refined
A collection of six papers published in UOG show that, despite full standard investigation, in the majority of cases of stillbirth the cause remains unknown. The papers highlight the need for further research to improve postmortem techniques to better detect a cause of death. The collection will be published in a special issue on pregnancy loss in November. Read the press release and author commentary.

-------------------------------------------------------------------------------------------------------------06/2016 - NEW UOG Impact Factor!
We are delighted to announce that the impact factor for UOG has achieved a dramatic increase and is now the highest it's ever been at 4.254 and is a reflection of the broadening range of clinically relevant content published each month. UOG is now ranked as 7th out of 80 journals in the obstetrics and gynecology category and is considered the leading peer-reviewed international journal on imaging in obstetrics and gynecology.

03/2016 - ISUOG Interim Guidance on Zika virus in pregnancy
In response to the World Health Organization statements and international concerns regarding the Zika virus (ZIKV) outbreak, ISUOG has published guidance for ultrasound during pregnancy.
With the current uncertainty regarding many aspects of the diagnosis and clinical course of ZIKV infection in pregnancy, potentially valuable information may be obtained by ultrasound practitioners that may help in counseling pregnant women and further improve our understanding of the pathophysiology of ZIKV infection in pregnancy.

-------------------------------------------------------------------------------------------------------------02/2016 - ISUOG Practice Guidelines:  role of ultrasound in twin pregnancy
New ISUOG Practice Guidelines published in the February issue of UOG that address the role of ultrasound in the care of uncomplicated twin pregnancy and those complicated by twin–twin transfusion syndrome (TTTS), selective fetal growth restriction, twin anemia–polycythemia sequence (TAPS), twin reversed arterial perfusion sequence, conjoined twins and single intrauterine death. The document provides guidance on the methods used to determine gestational age and chorionicity, screening for chromosomal and structural abnormalities, and screening for TTTS, TAPS, growth abnormalities and preterm birth.

01/2016 - PHYSICIAN ALERT: Zika virus and microcephaly
A recent outbreak of the mosquito-borne Zika virus has been reported in South America and the Pacific region. Associated with the rapid increase in affected cases is the worrying increase in diagnoses of fetal microcephaly throughout Brazil, with almost 3000 cases reported by the end of December 2015. Vertical transmission of Zika virus from mother to fetus has not yet been documented; however a recent report from the state of Paraiba, Brazil, has identified two women with intrauterine transmission of the virus, which was confirmed by sequencing of amniocentesis samples. This virus appears to be the cause behind the microcephaly outbreak, which clearly represents a severe health threat that needs to be acted on imminently.

Recently published observations in Ultrasound in Obstetrics & Gynecology indicate that healthcare professionals should be aware of fetal imaging findings, particularly of the brain and head size, when performing ultrasound examinations on pregnant women who reside in, or have visited recently, areas in which Zika virus is known to be prevalent. Evidence from the published case descriptions suggests that women presenting with viral symptoms should be tested for Zika virus and, if found to be positive, the fetus should be assessed for potential effects on brain development. In the evaluation of a fetus with microcephaly, brain calcifications eye anomalies and/or cerebellar hypoplasia, maternal testing and amnio-PCR for detection of Zika virus should be considered.

For full details please read our Physician Alert published today in Ultrasound in Obstetrics & Gynecology (UOG).

02/2014 - RCT demonstrates use of ultrasound in identifying women who will most benefit from vaginal mesh surgery
Published in the upcoming April issue of UOG, but available now as an Early View article online, is a randomized controlled trial providing new evidence that pelvic floor ultrasound imaging can identify individual women who are most likely to benefit from vaginal mesh surgery. Read the press release and author commentary.

02/2014 - NIPT in UOG
The March issue  features two important articles on the application of non-invasive prenatal testing (NIPT) for the detection of chromosomal abnormalities in the fetus. The first article (Lau et al.) uses genome-wide sequencing in a large series of 1982 consecutive cases, reporting on the clinical performance of NIPT in this setting. The second article (Petersen et al.), by contrast, uses a targeted probe approach in a population-based study to estimate the proportion of common chromosomal abnormalities that would be detectable using different screening strategies.


Referee Commentaries
From July 2012, each issue of the Journal has included Referee Commentaries on selected articles. These are commissioned by the Editors when they feel that a Reviewer of a manuscript can provide an additional perspective or insight on the research presented.
