Abstract
Dolutegravir (DTG) is one of the most prescribed antiretroviral drugs for treating people with HIV infection, including women of child-bearing potential or pregnant. Nonetheless, neuropsychiatric symptoms are frequently reported. Early reports suggested that, probably in relation to folic acid (FA) shortage, DTG may induce neural tube defects in infants born to women taking the drug during pregnancy. Subsequent reports did not definitively confirm these findings. Recent studies in animal models have highlighted the association between DTG exposure in utero and congenital anomalies, and an increased risk of neurologic abnormalities in children exposed during in utero life has been reported. Underlying mechanisms for DTG-related neurologic symptoms and congenital anomalies are not fully understood. We aimed to deepen our knowledge on the neurodevelopmental effects of DTG exposure and further explore the protective role of FA by the use of zebrafish embryos. We treated embryos at 4 and up to 144 h post fertilization (hpf) with a subtherapeutic DTG concentration (1 μM) and observed the disruption of the anterior-posterior axis and several morphological malformations in the developing brain that were both prevented by pre-exposure (2 hpf) and rescued by post-exposure (10 hpf) with FA. By whole-mount in situ hybridization with riboprobes for genes that are crucial during the early phases of neurodevelopment (ntl, pax2a, ngn1, neurod1) and by in vivo visualization of the transgenic Tg(ngn1:EGFP) zebrafish line, we found that DTG induced severe neurodevelopmental defects over time in most regions of the nervous system (notochord, midbrain-hindbrain boundary, eye, forebrain, midbrain, hindbrain, spinal cord) that were mostly but not completely rescued by FA supplementation. Of note, we observed the disruption of ngn1 expression in the dopaminergic regions of the developing forebrain, spinal cord neurons and spinal motor neuron projections, with the depletion of the tyrosine hydroxylase (TH)+ dopaminergic neurons of the dorsal diencephalon and the strong reduction in larvae locomotion. Our study further supports previous evidence that DTG can interfere with FA pathways in the developing brain but also provides new insights regarding the mechanisms involved in the increased risk of DTG-associated fetal neurodevelopmental defects and adverse neurologic outcomes in in utero exposed children, suggesting the impairment of dopaminergic pathways.

Abstract
Fetal anomalies, characterized by structural or functional abnormalities occurring during intrauterine life, pose a significant medical challenge, with a notable prevalence, affecting approximately 2-3% of live births and 20% of spontaneous miscarriages. This study aims to identify the genetic cause of ultrasound anomalies through clinical exome sequencing (CES) analysis. The focus is on utilizing CES analysis in a trio setting, involving the fetuses and both parents. To achieve this objective, prenatal trio clinical exome sequencing was conducted in 51 fetuseses exhibiting ultrasound anomalies with previously negative results from chromosomal microarray (CMA) analysis. The study revealed pathogenic variants in 24% of the analyzed cases (12 out of 51). It is worth noting that the findings include de novo variants in 50% of cases and the transmission of causative variants from asymptomatic parents in 50% of cases. Trio clinical exome sequencing stands out as a crucial tool in advancing prenatal diagnostics, surpassing the effectiveness of relying solely on chromosomal microarray analysis. This underscores its potential to become a routine diagnostic standard in prenatal care, particularly for cases involving ultrasound anomalies.

Abstract
Stillbirth impacts 5.73 per 1,000 births in the United States and this rate exceeds that of contemporary high-resource countries.1,2 Risk factors include both demographic and medical characteristics. There are also numerous pathophysiologic mechanisms that can lead to stillbirth. Unfortunately, these risk factors are fairly common, making stillbirth risk stratification and prevention challenging. This is due in part to a large number of unexplained stillbirths. In a large, multi-center study of stillbirths, approximately 24% of stillbirths remained unexplained following thorough, standardized evaluation.3 The number of unexplained stillbirths is unquestionably larger outside of a rigorous study protocol, but real-world data are lacking. This large proportion of unexplained stillbirth cases makes achieving further decreases in the stillbirth rate difficult given lack of understanding of underlying causes in this population. Cause of death identification can be improved with adoption of an evidence-based, comprehensive stillbirth evaluation.

Abstract
BACKGROUND Crown-rump length discordance, defined as ≥10% discordance, has been investigated as an early sonographic marker of subsequent growth abnormalities and is associated with an increased risk of fetal loss in twin pregnancies. Previous studies have not investigated the prevalence of fetal aneuploidy or structural anomalies in twins with discordance or the independent association of crown-rump length discordance with adverse perinatal outcomes. Moreover, data are limited on cell-free DNA screening for aneuploidy in dichorionic twins with discordance. OBJECTIVE This study aimed to evaluate whether crown-rump length discordance in dichorionic twins between 11 and 14 weeks of gestation is associated with a higher risk of aneuploidy, structural anomalies, or adverse perinatal outcomes and to assess the performance of cell-free DNA screening in dichorionic twin pregnancies with crown-rump length discordance. STUDY DESIGN This was a secondary analysis of a multicenter retrospective cohort study that evaluated the performance of cell-free DNA screening for the common trisomies in twin pregnancies from December 2011 to February 2020. For this secondary analysis, we included live dichorionic pregnancies with crown-rump length measurements between 11 and 14 weeks of gestation. First, we compared twin pregnancies with discordant crown-rump lengths with twin pregnancies with concordant crown-rump lengths and analyzed the prevalence of aneuploidy and fetal structural anomalies in either twin. Second, we compared the prevalence of a composite adverse perinatal outcome, which included preterm birth at <34 weeks of gestation, hypertensive disorders of pregnancy, stillbirth or miscarriage, small-for-gestational-age birthweight, and birthweight discordance. Moreover, we assessed the performance of cell-free DNA screening in pregnancies with and without crown-rump length discordance. Outcomes were compared with multivariable regression to adjust for confounders. RESULTS Of 987 dichorionic twins, 142 (14%) had crown-rump length discordance. The prevalence of aneuploidy was higher in twins with crown-rump length discordance than in twins with concordance (9.9% vs 3.9%, respectively; adjusted relative risk, 2.7; 95% confidence interval, 1.4-4.9). Similarly, structural anomalies (adjusted relative risk, 2.5; 95% confidence interval, 1.4-4.4]) and composite adverse perinatal outcomes (adjusted relative risk, 1.2; 95% confidence interval, 1.04-1.3) were significantly higher in twins with discordance. A stratified analysis demonstrated that even without other ultrasound markers, there were increased risks of aneuploidy (adjusted relative risk, 3.5; 95% confidence interval, 1.5-8.4) and structural anomalies (adjusted relative risk, 2.7; 95% confidence interval, 1.5-4.8) in twins with CRL discordance. Cell-free DNA screening had high negative predictive values for trisomy 21, trisomy 18, and trisomy 13, regardless of crown-rump length discordance, with 1 false-negative for trisomy 21 in a twin pregnancy with discordance. CONCLUSION Crown-rump length discordance in dichorionic twins is associated with an increased risk of aneuploidy, structural anomalies, and adverse perinatal outcomes, even without other sonographic abnormalities. Cell-free DNA screening demonstrated high sensitivity and negative predictive values irrespective of crown-rump length discordance; however, 1 false-negative result illustrated that there is a role for diagnostic testing. These data may prove useful in identifying twin pregnancies that may benefit from increased screening and surveillance and are not ascertained by other early sonographic markers.

Abstract
PURPOSE Comparison of intracytoplasmic sperm injection cycles with testicular sperm extraction in obstructive azoospermia and non-obstructive azoospermia are limited, and few studies have addressed obstetric and neonatal outcomes. DESIGN This study analyzed couples who underwent testicular sperm extraction-intracytoplasmic sperm injection cycles for obstructive azoospermia and non-obstructive azoospermia to determine whether impaired spermatogenesis in non-obstructive azoospermia patients would lead to worse reproductive outcomes and higher rates of pregnancy complications and fetal anomalies. This study is a retrospective, single-center analysis of all testicular sperm cycles performed between January 1, 2001 and December 31, 2020. RESULTS A total of 392 couples were considered in the study, leading to 1066 induction cycles, 620 (58.2%) from patients with obstructive azoospermia and 446 (41.8%) from non-obstructive azoospermia. The cumulative delivery rate did not significantly differ between the two groups (34% vs. 31%; p = 0.326). The miscarriage rate was similar between obstructive azoospermia and non-obstructive azoospermia patients. Fertilization rate instead showed a statistically significant difference (obstructive azoospermia: 66.1 ± 25.7 vs. non-obstructive azoospermia: 56.1 ± 27.0; p < 0.001). The overall maternal complication rate in the non-obstructive azoospermia group was higher (10.7% vs. 18.4%; p = 0.035), but there was no statistical significance for each pathology. There was no statistical difference in gestational age between the two groups for both single and twin pregnancies. Seven cases of congenital defects occurred in the obstructive azoospermia group, while two cases occurred in the non-obstructive azoospermia group. CONCLUSIONS Despite impaired spermatogenesis in non-obstructive azoospermia patients, there were no substantial differences in reproductive outcomes compared to patients with obstructive azoospermia, even in terms of obstetric safety and neonatal well-being.

Abstract
INTRODUCTION CREBBP truncating mutations and deletions are responsible for the well-known Rubinstein-Taybi syndrome. Recently, a new, distinct CREBBP-linked syndrome has been described: missense mutations located at the 3' end of exon 30 and the 5' portion of exon 31 induce Menke-Hennekam syndrome. Patients with this syndrome present a recognizable facial dysmorphism, intellectual disability of variable severity, microcephaly, short stature, autism, epilepsy, visual and hearing impairments, feeding problems, upper airway infections, scoliosis, and/or kyphosis. To date, all diagnoses were made postnatally. METHOD AND CASE REPORT Trio-whole exome sequencing (WES) was performed in a fetus showing increased nuchal translucency persistence and aorta abnormalities at 28 weeks of gestation (WG). RESULTS WES revealed a CREBBP de novo missense mutation (c.5602C>T; p.Arg1868Trp) in exon 31, previously reported as the cause of Menke-Hennekam syndrome. Termination of pregnancy was performed at 32 WG. We further reviewed the prenatal signs of Menke-Hennekam syndrome already reported. Among the 35 patients reported and diagnosed postnatally up to this day, 15 presented recognizable prenatal signs, the most frequent being intra-uterine growth retardation, brain, and cardiovascular anomalies. CONCLUSION Menke-Hennekam is a rare syndrome with unspecific, heterogeneous, and inconstant prenatal symptoms occurring most frequently with the c.5602C>T, p.(Arg1868Trp) mutation. Therefore, the prenatal diagnosis of Menke-Hennekam syndrome is only possible by molecular investigation. Moreover, this case report and review reinforce the importance of performing prenatal WES when unspecific signs are present on imaging.

Abstract
The sonographic findings in four fetuses presenting with ventriculomegaly at first-trimester ultrasound that were subsequently diagnosed as having agenesis of the corpus callosum (ACC) are described. The diagnosis of early ventriculomegaly was suspected subjectively by identification of increased cerebrospinal fluid within the lateral ventricles and confirmed by measuring choroid plexus-to-lateral ventricle length and area ratios. Subsequent scans revealed complete ACC in two cases and partial ACC in the other two. This report adds to the increasing evidence suggesting that first-trimester ventriculomegaly is a strong sonographic marker of underlying brain anomalies, including less evident malformations such as ACC. Detailed second-trimester fetal neurosonography in those women continuing their pregnancies should be performed.

Abstract
OBJECTIVE Ultrasound assessment of the fetal anatomy and fetal echocardiography are feasible in the first trimester of pregnancy. This study was designed to assess the performance of a comprehensive fetal anatomy assessment in a high-risk population at a tertiary fetal medicine unit. METHODS Retrospective review of high-risk patients undergoing comprehensive fetal anatomy ultrasound assessment between 11 weeks and 13+6 weeks gestation was conducted. Findings of the early anatomy ultrasound scan were compared with the second trimester anatomy scan, and birth outcomes or post-mortem results. RESULTS Early anatomy ultrasounds were performed in 765 patients. Sensitivity of the scan for detecting fetal anomalies compared to the birth outcome was 80.5% (95% CI 73.5 -86.3) and specificity was 93.1% (95%CI 90.6 - 95.2). Positive and negative predictive values were 78.5% (95% CI 71.4 - 84.6) and 93.9 % (95% CI 91.4 - 95.8), respectively. The most missed and the most overdiagnosed abnormalities were ventricular septal defects. The second trimester ultrasound had sensitivity of 69.0% (95% CI 55.5 - 80.5) and specificity of 87.5% (95% CI 84.3 - 90.2). CONCLUSION In a high-risk population, early assessments had similar performance metrics as the second trimester anatomy ultrasound. We advocate for a comprehensive fetal assessment in the care of high-risk pregnancies. This article is protected by copyright. All rights reserved.

Abstract
The long-term monitoring of a fetus with genetic and non-genetic anomalies is still a challenge for prenatal medicine. Ultrasound screening must be based on some measurement ranges, which show the trend of development of fetal body parts in a given period of time. One of them is the fetal ear auricle. This study presents an analysis of the fetal ear auricle length in healthy fetuses to establish normal ranges of fetal ear auricle length. The study group included 132 healthy fetuses. The gestational age of healthy fetuses ranged from 17.0 to 39.5 weeks of gestation according to LMP. The range of fetal ear length measurement was 10.00-40.00 mm with an average value of 23.49 mm. In the group of fetuses in the second trimester of pregnancy, the range of fetal ear length measurement was 18.00-28.00 mm, whereas in the group of fetuses in the third trimester of pregnancy, the range was 16.00-40.00 mm. In order to check the usefulness of this parameter, an analysis of this marker in fetuses with extracardiac anomalies, including genetic and non-genetic disorders is shown. The fetal ear measurement can fall within the normal range even if there are some genetic or non-genetic disorders. Therefore, the fetal ear measurement does not provide any diagnostic value in terms of detecting any fetal genetic and non-genetic disorders, which is supported by the analysis of the data provided in this study. Our study has proved that measurement of the fetal ear auricle is possible; however, its clinical usefulness for perinatal management is currently very limited.

Abstract
OBJECTIVES Maternal urogenital infections during pregnancy are worldwide frequent problem. The aim was to analyze influence of maternal genitourinary infection on fetal cardiac function, pregnancy development and obstetrical outcomes. METHODS This was a single-center cohort study on fetuses (average at 28th week) in two groups: with maternal urogenital infections (study group n=49) and control group with no infections (n=59). Parvovirus B19, toxoplasmosis, cytomegalovirus, herpes simplex infections, congenital malformations, fetal growth restriction, chronic maternal diseases, as well as patients with body mass index (BMI) >25 kg/m2 were excluded. We analyzed: maternal age, time of delivery, neonatal birth weight, Apgar scores, average time of hospitalization of newborns after birth and several fetal echocardiographic parameters. RESULTS The only statistical differences was found for shorter isovolumetric relaxation time (IRT) (40 ± 10 vs. 45 ± 9; p=0.03) and longer ejection time (ET) [ms] for right ventricle (RV) (176 ± 24 vs. 164 ± 18; p=0.01). Thick placenta was observed more frequent in study group than in controls (36.7 vs. 16.9%; p= 0.02). CONCLUSIONS The missing link for explanation of these findings was coincidence with thick placenta. This is probably the first observation suggesting that thick placenta (>5 cm) may affect fetal RV function in normal heart anatomy: prolongation of right ventricular ET and shortening of fetal right ventricular IVRT.

Abstract
Objective: The aim of this study is to compare the prenatal ultrasonography (US) and the autopsy findings of the fetuses of 12-24th gestational weeks. Methods: This retrospective study comprises 84 fetuses autopsied. The correlation between US and autopsy findings was classified into four categories: (A) Compatible, (B) Minor findings added, (C) Major findings added, and (D) Incompatible. Results: Malformations were the most common medical termination indication. The most frequent findings at autopsy were multiple system findings followed by central nervous system. Prenatal US and autopsy findings were completely compatible in 48 fetuses (57.1%), while additional minor and major autopsy findings were found in 26 (31.0%) and 4 (4.8%), respectively. Autopsy and US findings were incompatible in 6 fetuses (7.1%). Conclusion: Prenatal ultrasound and fetal autopsy are complementary tools to obtain detailed and complete diagnosis of fetal anomalies and fetal autopsy is still a valuable tool to obtain further diagnostic information.

Abstract
Introduction Advancements in prenatal diagnostic techniques have led to an increase in demand for termination of pregnancy for fetal anomalies (TOPFA). While relaxation in the legal gestational age limits across various countries relieves an important barrier, there is a need to identify the reasons that lead to delays in seeking abortion for fetal anomalies, because abortion-related complications increase with gestational age. Methods In this hospital-based qualitative study, antenatal women referred to a tertiary care institute in North India because of major fetal anomalies were explained about the study. Those women who fulfilled the inclusion criteria were recruited after taking consent. Details of antenatal care and prenatal tests were recorded. An in-depth inquiry was made into the reasons for the delay in prenatal tests, the delay in the decision for abortion, and specific problems that they faced in seeking TOPFA. Results Out of 80 women who met the inclusion criteria and consented to participate, more than 75% had received antenatal care in public healthcare facilities. Less than 50% of women received folic acid in the first trimester while 26% had first contact with healthcare facilities in the second trimester. Only 21 women underwent screening for common aneuploidies. Second-trimester anomaly scan was delayed in 35 women due to women-centered reasons (n = 17) or provider-centered (n = 19) reasons. Only 37.5% of women were counseled about fetal anomalies by their primary care provider. Owing to delay at multiple levels, 40 women (50%) could receive counseling about fetal abnormality for the first time after 20 weeks. These women could not be offered abortion because this study was carried out before the amendments in the Medical Termination of Pregnancy Act in India. The older act allowed abortion up to 20 weeks of gestation. Seventeen women could obtain permission for an abortion from a court of law. Arrangements for travel and stay and dependence on family members were the main problems faced by women seeking TOPFA. Conclusions Delay in diagnosis of a fetal anomaly due to delay in seeking antenatal care, irregular follow-up, and lack of pre-test counseling are the major reasons for the delay in the decision for abortion. This is further compounded by inadequate post-test counseling. Lack of awareness, failure or delay in counseling, need to travel to another facility for abortion, dependence on family members, and financial issues are the major barriers.

Abstract
Professionals who work in perinatal care must understand the advantages and disadvantages of perinatal autopsy since they are an essential tool for determining fetal and neonatal mortality. Perinatal is the period five months before one month after birth, while prenatal is before birth. The traditional prenatal autopsy is still the gold standard for establishing the cause of death and providing an accurate report, notwithstanding the development of new technology. The ideal locations for a prenatal autopsy are tertiary institutes that offer these procedures. It emphasizes the need for systematic histopathologic sampling, rigorous record-keeping, technological adaptation, and wise laboratory test use. When a laboratory does a microbiologic examination with a focus on the genital tract and neonatal problems, it is very beneficial. Karyotyping needs to be selective and works best when there are many aberrations if resources are to be saved. A perinatal autopsy is insufficient without examining the placenta, and severe lesions should be distinguished from deformities and abnormalities brought on by fetal death. In addition to providing epidemiology teams and auditing committees with high-quality data, the pathologist's role in perinatal medicine also includes participating in the multidisciplinary management of fetal abnormalities identified during pregnancy, monitoring the patterns of iatrogenic disease, and aiding the perinatal grief management process. Investigations into complicated multiple pregnancies, hydrops, bone dysplasias, and unexpected intrauterine fetal deaths provide unique obstacles and diagnostic difficulties. There hasn't been any research that contrasts postmortem computed tomography with postmortem x-rays in pregnant women, as far as we know. Histological analysis of many perinatal autopsies revealed healthy developing tissues. Only a tiny percentage of histological abnormalities can be expected in fetal anomaly terminations. On prenatal imaging, many organ abnormalities are commonly anticipated. A thorough database search was done in Pubmed, Medline, and Scopus using the phrases "fetal abnormalities," "karyotyping," "fetal abnormality," "postmortem," and "perinatal autopsy."

Abstract
AIM We assessed the feasibility of the Birth and Parenting Planning (BPPing) program we developed to support women diagnosed with fetal anomalies. METHODS We conducted a feasibility study using a quasi-experimental, post-test only, non-equivalent groups design. We assessed feasibility from four aspects: (1) Demand: birth plan submitting rate (primary outcome); (2) Acceptability: woman's satisfaction of care scale (SATISFACTION) and Visual Analog Scale for care satisfaction; (3) Preliminary efficacy: women's recognition of being able to express and share her hopes scale (HOPES); and (4) Safety: obstetric/neonatal outcomes and frequency of women's referral to a psychological counselor. Fisher's exact test and Mann-Whitney U-test were used for data analysis. RESULTS We enrolled 62 women with fetal anomalies attending a perinatal medical center for antenatal check-ups. Of these, 51 women (median age: 34 years) received either the BPPing program (intervention group: n = 25) or the usual care (control group: n = 26). The birth plan submitting rates were 96% (intervention group, 24/25) and 7.7% (control group, 2/26). The intervention group had a significantly higher total score on HOPES at postpartum (U = 441.5, p = 0.027). Upon subgroup analysis based on parity, in the intervention group only, the multiparas had a higher score on the SATISFACTION item, "I would recommend the care I received to someone in a similar situation". There were no adverse events in either group. CONCLUSION The BPPing program was feasible in supporting women diagnosed with fetal anomalies in terms of demand, acceptability, preliminary efficacy, and safety.

Abstract
With the recent overturning of Roe V. Wade by the Supreme Court, access to abortions in many regions across the United States will become very limited as laws regarding fetal termination will be determined by state legislators rather than on a federal level. This article highlights the effects of Roe V. Wade's abolishment on individuals that can get pregnant, how unwanted pregnancies will affect society in general, and reasonable steps forward following the ban. We conducted an electronic search using PubMed, Google, and Google Scholar. The search was retrospective, and the preliminary results focused on articles about the rationale behind pregnancy termination and the overall effects of abortion and the ban. Review papers, original papers, and newspaper articles were eligible for use. Sample size and region of publication were not exclusionary criteria. Each author independently reviewed and extracted data to write up each assigned section, and group collaborations occurred to create the final draft. Out of the 93 resources reviewed, 32 sources were deemed eligible and used in this article. These resources included 23 journal articles, eight websites, and one book.. The data gathered showed that while abortions have many potential complications even when performed under regulated conditions, taking away the choice of those with a uterus is also not without consequence. The economic, familial, and societal implications should be considered moving forward as safety nets will need to be implemented for people with uterus and children involved.

Abstract
Conjoined twins represent a very rare congenital anomaly, and the dicephalic dibrachius dipus (DDD) type of conjoined twinning is so rare that the exact prevalence is unknown. Only a few published case studies have mentioned this anomaly. Not enough data are available where antenatal ultrasonography (USG) and MRI have been employed in the workup of such cases. This study describes the case of a 24-year-old woman who came to our department for an anomaly scan at 25 weeks of gestation and was diagnosed with a dicephalic type of conjoined twinning with multiple anomalies. However, USG could not differentiate between DDD twinning and craniopagus parasiticus; hence, the patient was referred for fetal MRI. On MRI, the diagnosis of DDD was confirmed. In craniopagus parasiticus twinning, the surgical removal of the parasitic head can allow an everyday life. However, DDD twinning with multiple anomalies is not compatible with life, and the mother was thoroughly explained the grave prognosis. In such doubtful cases, fetal MRI should always be employed to ascertain the diagnosis for proper management and counseling.

Abstract
BACKGROUND Telemedicine can extend essential health services to under-resourced settings and improve the quality of obstetrical care. Specifically, the evaluation and management of fetal anomalies require perinatal subspecialists, rendering prenatal diagnosis essential, and may benefit from telemedicine platforms to improve access to care. OBJECTIVE This study aimed to evaluate the impact of a maternal-fetal medicine telemedicine ultrasound program on the diagnostic accuracy of fetal anomalies when used within practices where ultrasounds are interpreted by general obstetricians or family medicine physicians. STUDY DESIGN This was a cross-sectional study of all patients receiving care at 11 private obstetrical practices and imaging centers who had obstetrical ultrasounds performed from January 1, 2020, to July 6, 2020. All ultrasounds were performed by sonographers remotely trained under a standardized protocol and interpreted by maternal-fetal medicine physicians via telemedicine. Ultrasound characteristics and interpretation were extracted from ultrasound reports. Before the introduction of maternal-fetal medicine telemedicine, all ultrasound interpretations were reviewed by general obstetricians and family medicine physicians with reliance predominantly on the sonographer's impression. The primary outcome was potential missed diagnosis of a fetal anomaly, defined as an ultrasound designated as normal by a sonographer but diagnosed with an anomaly by a maternal-fetal medicine physician via telemedicine. This outcome serves as a proxy measure for anomaly diagnoses that would likely be missed without the supervision of a maternal-fetal medicine physician. The characteristics of the potential missed diagnoses were compared by type of scan and fetal organ system in univariable analysis. Moreover, a survey was conducted for sonographers and obstetrical providers to assess their perceptions of ultrasound interpretation via telemedicine. RESULTS Overall, 6403 ultrasound examinations were evaluated, 310 of which had a diagnosis of fetal anomaly by a maternal-fetal medicine physician (4.8%). Of the fetal anomalies, 43 were diagnosed on an anatomic survey (13.9%), and 89 were diagnosed as cardiac anomalies (28.7%). The overall rate of the potential missed diagnoses was 34.5% and varied significantly by type of ultrasound (anatomy scans vs other first-, second-, and third-trimester ultrasounds) (P<.01). Moreover, there were significant differences in the rate of the potential missed diagnoses by organ system, with the highest rate for cardiac anomalies (P<.01). CONCLUSION Expertise in maternal-fetal medicine telemedicine improves the diagnostic performance of antenatal ultrasound throughout pregnancy. However, there are implications for improving the quality of antenatal care, such as ensuring appropriate referrals and site of delivery, particularly for cardiac anomalies.

Abstract
BACKGROUND Gastroschisis and omphalocele are congenital abdominal wall defects in which the bowel and other abdominal contents extrude from the fetal abdominal cavity. Standard formulas for estimated fetal weight using ultrasound include fetal abdominal circumference measurement and have a range of error of approximately 10%. It is unknown whether the accuracy of estimated fetal weight assessment is compromised in fetuses with abdominal wall defects because of the extrusion of abdominal contents. OBJECTIVE This study aimed to assess the accuracy of standard estimated fetal weight assessment in fetuses with abdominal wall defects by comparing prenatal assessment of fetal weight with actual birthweight. STUDY DESIGN A retrospective cohort study of fetuses diagnosed with gastroschisis or omphalocele was performed at a single center from 2012 to 2018. Fetuses with additional anomalies or confirmed chromosome abnormalities were excluded. Estimated fetal weight was calculated using the Hadlock formula. Published estimates of fetal growth rate were used to establish a projected estimated fetal weight at birth from the final growth ultrasound, and the percent difference between projected estimated fetal weight at birth and actual birthweight was calculated. The Wilcoxon rank-sum test was used to examine the difference between projected estimated fetal weight and actual birthweight. RESULTS We had complete data for 112 fetuses with abdominal wall defects, including 85 with gastroschisis and 27 with omphalocele. The median (interquartile range) projected estimated fetal weight was similar to median birthweight, at 2283 g (interquartile range, 2000-2810) and 2306 g (interquartile range, 1991-264), respectively, which did not represent a statistically significant difference between projected estimated fetal weight and actual birthweight (P=.32). The median percent error was 6.8 (3.1-12.8). In addition, we did not find any statistical difference between projected estimated fetal weight and actual birthweight in patients with gastroschisis (P=.52) or omphalocele (P=.35) individually. Estimated fetal weight was underestimated in most cases (n=68 [60.7%]). CONCLUSION In fetuses with abdominal wall defects, standard measurement of fetal weight shows an accuracy that is at least comparable with previously established margins of error for ultrasound assessment of fetal weight. Standard estimated fetal weight assessment remains an appropriate method of estimating fetal weight in these fetuses.

Abstract
OBJECTIVE This study aimed to synthesize the qualitative literature on parental experiences of fetal care to reflect events that happened across the continuum of care and to better understand parents' positive and negative experiences with care delivery. DATA SOURCES Eligible studies published until June 2020 were retrieved from MEDLINE, Embase, Cochrane Central Register of Controlled Trials, EBSCO CINAHL, Web of Science, and ProQuest. STUDY ELIGIBILITY CRITERIA Studies must have been: (1) published in English in a peer-reviewed journal or in ProQuest, (2) available in full text, (3) contained a qualitative component, and (4) focused on expectant parents' experiences of tertiary, coordinated, multidisciplinary prenatal diagnosis and care related to a fetal anomaly. STUDY APPRAISAL AND SYNTHESIS METHODS Researchers used the Joanna Briggs Institute Critical Appraisal Checklist for Qualitative Research. A metastudy and an interpretive description approach was taken to synthesize the events that happened across the continuum of care and the themes associated with a positive care experience. RESULTS The metasynthesis included 13 studies and 217 patients from 11 different multidisciplinary fetal diagnosis and intervention practices across North America and Europe. We identified key events that influenced parental experience of fetal care across the continuum. The themes associated with a positive care experience are parents (1) gaining understanding and feeling understood, (2) realizing agency and control, and (3) finding hope and meaning. We identified aspects of healthcare delivery that served as barriers or facilitators to these positive experiences. CONCLUSION Understanding the commonalities of the parental experience of fetal care across diverse settings creates a foundation for improving care and better meeting the needs of parents undergoing a painful and life-defining event. Although health outcomes are not always positive, a positive experience of care is possible and can assist parents to cope with their grief, manage their expectations, and engage in their care. The findings of this study illustrate the ways in which healthcare delivery can facilitate or obstruct a positive care experience.

Abstract
INTRODUCTION The aim of this retrospective cohort study was to determine the potential diagnostic yield of prenatal whole exome sequencing in fetuses with structural anomalies on expert ultrasound scans and normal chromosomal microarray results. MATERIAL AND METHODS In the period 2013-2016, 391 pregnant women with fetal ultrasound anomalies who received normal chromosomal microarray results, were referred for additional genetic counseling and opted for additional molecular testing pre- and/or postnatally. Most of the couples received only a targeted molecular test and in 159 cases (40.7%) whole exome sequencing (broad gene panels or open exome) was performed. The results of these molecular tests were evaluated retrospectively, regardless of the time of the genetic diagnosis (prenatal or postnatal). RESULTS In 76 of 391 fetuses (19.4%, 95% CI 15.8%-23.6%) molecular testing provided a genetic diagnosis with identification of (likely) pathogenic variants. In the majority of cases (91.1%, 73/76) the (likely) pathogenic variant would be detected by prenatal whole exome sequencing analysis. CONCLUSIONS Our retrospective cohort study shows that prenatal whole exome sequencing, if offered by a clinical geneticist, in addition to chromosomal microarray, would notably increase the diagnostic yield in fetuses with ultrasound anomalies and would allow early diagnosis of a genetic disorder irrespective of the (incomplete) fetal phenotype.

Abstract
OBJECTIVES To evaluate fetal anomaly detection in pregnancies with pregestational diabetes, according to the gestational age at the time of specialized sonography, use of follow-up sonography, maternal body mass index, and organ system(s) involved. METHODS Women with pregestational diabetes who received prenatal care and delivered a live-born or stillborn neonate at our hospital from October 2011 through April 2017 were ascertained. We included all pregnancies with at least 1 confirmed structural anomaly (EUROCAT classification) who had detailed sonography at 18 weeks' gestation or later. We analyzed detection of anomalous fetuses at the initial detailed sonogram and, if no abnormality was identified, during any follow-up sonograms. Statistical analyses were performed with the χ2 test and Mantel-Haenszel χ2 test for trend. RESULTS Seventy-two anomalous neonates (72 of 1060 [6.8%]) were born. Overall detection was 55 of 72 (76%); 49 of 72 (68%) were detected at the initial detailed sonogram, compared to 6 of 15 (40%) of follow-up examinations (P = .04). Recognition at the initial or follow-up examination was not dependent on gestational age or body mass index category (all P > .05). Of individual organ system anomalies, 67 of 89 (75%) were identified. Detection exceeded 85% for central nervous system, genitourinary, and musculoskeletal abnormalities and 43% for craniofacial anomalies. Sixty-five percent of cardiac anomalies were detected, and 14 of 17 (82%) requiring specialized care in the immediate neonatal period were recognized. CONCLUSIONS Approximately three-fourths of anomalous fetuses were identified, with greater detection at the initial detailed examination. Fetuses with central nervous system, genitourinary, musculoskeletal abnormalities and those with cardiac anomalies requiring specialized cardiac care were more likely to come to attention.

Abstract
OBJECTIVE To evaluate the incidence and types of chromosomal abnormalities in pregnancy loss and aborted fetuses with anomaly and compare the performance of subtelomeric MLPA and chromosomal microarray analysis (CMA) in these specimens. METHODS Samples were collected from spontaneous miscarriages, stillbirths and aborted fetuses with anomaly between January 2015 and April 2019. Chromosomal abnormalities were detected using subtelomeric MLPA and CMA. RESULTS Among the 172 miscarriage samples, CMA detected pathogenic chromosomal abnormalities in 88 cases. MLPA could identified all aneuploidies and most pathogenic CNVs, missing all polyploidies; Of the 30 stillbirths, one pathogenic CNV and two VOUS were identified by CMA, all of which were missed from MLPA; Of the 135 aborted fetuses with anomaly, CMA identified pathogenic chromosomal abnormalities in 32 fetuses (23.7%); 18.95% in fetuses with isolated, and 35% in fetuses with multiple anomalies. MLPA can identify all aneuploidies but missing most pathogenic CNVs. CONCLUSION Our systematical comparison of subtelomeric MLPA and CMA for chromosomal analysis of tissue from pregnancy loss and aborted fetuses with anomaly is useful for assessing clinical utility of these techniques. MLPA screening, coupled with CMA analysis, is a cost-effective approach to detect chromosomal abnormalities in miscarriage and anomalous fetuses. However, MLPA might not be appropriate for chromosome analysis in stillbirth without structural anomaly; further research with more samples is needed.

Abstract
INTRODUCTION Complicated monochorionic twin pregnancies are often associated with high perinatal morbidity and mortality, some of which are severe enough to require a gestational reduction surgery to improve fetal survival and reduce disabilities. While radiofrequency ablation is currently the most commonly used procedure with higher fetal survival and fewer maternal and fetal complications compared with other surgical methods, the therapeutic effect of microwave ablation (MWA) is reported to be better, presumably due to the higher thermal effect and fewer restrictions. Currently there is limited evidence to prove the feasibility of MWA for selective reduction. The aim of this pilot study is to explore the feasibility, efficacy and safety of MWA reduction for severe complicated monochorionic pregnancies and may provide evidence for using the MWA in intrauterine surgeries extensively. METHODS AND ANALYSIS This is a study protocol for a parallel-design pilot randomised controlled trial. 60 eligible patients with severe complicated monochorionic pregnancies will be randomised in a ratio of 1:1 to MWA group and radiofrequency group. Patients will be followed up until 6 months of age of the retained fetal. The primary analysis will compare the rates of neonatal survival at 28 days to evaluate the effect of MWA. The study will also evaluate the safety profile of MWA including the occurrence of postoperative adverse events and maternal and fetal complications. Additional secondary outcomes to be explored include the condition of neonatal asphyxia and the growth of surviving fetus at 6 months. Outcomes will be analysed by both a frequentist and the Bayesian statistical approach. ETHICS AND DISSEMINATION This study was approved by the ethical review committee of the Peking University Third Hospital (Beijing, China). The results of this study will be published in peer-reviewed scientific journals and presented at relevant academic conferences. TRIAL REGISTRATION NUMBER NCT04014452; Pre-results.

Abstract
OBJECTIVE To evaluate delivery management and outcomes in fetuses prenatally diagnosed with CHD. STUDY DESIGN A retrospective cohort study was conducted on 6194 fetuses (born between 2013 and 2016), comparing prenatally diagnosed with CHD (170) to those with non-cardiac (234) and no anomalies (5790). Primary outcomes included the incidence of preterm delivery and mode of delivery. RESULTS Gestational age at delivery was significantly lower between the CHD and non-anomalous cohorts (38.6 and 39.1 weeks, respectively). Neonates with CHD had a significantly lower birth weights (p < 0.001). There was an approximately 1.5-fold increase in the rate of primary cesarean sections associated with prenatally diagnosed CHD with an odds ratio of 1.49 (95% CI 1.06-2.10). CONCLUSIONS Our study provides additional evidence that the prenatal diagnosis of CHD is associated with a lower birth weight, preterm delivery, and with an increased risk of delivery by primary cesarean section.

Abstract
OBJECTIVE To compare labor patterns in pregnancies affected by fetal anomalies to low-risk singletons. STUDY DESIGN Labor data from the Consortium on Safe Labor, a multicenter retrospective study from 19 U.S. hospitals, including 98,674 low-risk singletons compared with 6,343 pregnancies with fetal anomalies were analyzed. Repeated-measures analysis constructed mean labor curves by parity, gestational age, and presence of fetal anomaly in women who reached full dilation. Interval-censored regression analysis adjusted for covariables was used to determine the median traverse times for labor progression. RESULTS Labor curves for all groups indicated slower labor progress for patients with fetal anomalies. The most significant trends in median traverse times were observed in the preterm nulliparous and term multiparous groups. The median traverse times from 4 cm to complete dilation in the preterm nulliparous control versus anomaly groups were 5.0 and 5.4 hours (p < 0.0001). CONCLUSION Labor proceeds at a slower rate in pregnancies affected by anomalies.

Abstract
BACKGROUND Congenital diaphragmatic hernia is a congenital anomaly in which fetal abdominal organs herniate into the thoracic cavity through a diaphragmatic defect, which can impede fetal lung development. Standard formulas for estimated fetal weight include measurement of fetal abdominal circumference, which may be inaccurate in fetuses with congenital diaphragmatic hernia because of displacement of abdominal contents into the thorax. OBJECTIVES This study aimed to assess the accuracy of standard estimated fetal weight assessment in fetuses with congenital diaphragmatic hernia by comparing prenatal assessment of fetal weight with actual birthweight. STUDY DESIGN A retrospective cohort study of fetuses diagnosed with congenital diaphragmatic hernia was performed at a single center from 2012 to 2018. Fetuses with multiple anomalies or confirmed chromosome abnormalities were excluded. Estimated fetal weight was calculated using the Hadlock formula. Published estimates of fetal growth rate were used to establish a projected estimated fetal weight at birth from the final growth ultrasound, and the percentage difference between projected estimated fetal weight at birth and actual birthweight was calculated. A Wilcoxan rank-sum test was used to examine the difference between projected estimated fetal weight and birthweight. RESULTS We had complete data for 77 fetuses with congenital diaphragmatic hernia. The majority (76.6%, 55 of 77) had left-sided congenital diaphragmatic hernia. The median [interquartile range] projected estimated fetal weight was similar to median birthweight, at 3177 g [2691-3568] and 3180 g [2630-3500], respectively, which did not represent a statistically significant difference between projected estimated fetal weight and birthweight (P = .66). The median absolute percentage difference between projected birthweight and actual birthweight was 6.3% [3.2-7.0]. Estimated fetal weight was overall underestimated in a minority of cases (44.2%, 34 of 77). CONCLUSION In fetuses with a congenital diaphragmatic hernia, standard measurements of fetal estimated fetal weight show accuracy that is at least comparable with previously established margins of error for ultrasound assessment of fetal weight. Standard estimated fetal weight assessment remains an appropriate method of estimating fetal weight in fetuses with congenital diaphragmatic hernia.

Abstract
OBJECTIVES Central nervous system (CNS) anomalies are the second most frequent category of congenital anomalies after congenital heart defects (CHDs). In this study, the aim was to investigate the distribution of different CNS anomalies with associated anomalies and karyotype in a fetal autopsy population of terminated pregnancies over a 30-year period and to correlate the ultrasonographic diagnoses of CNS anomalies with autopsy findings. MATERIALS AND METHODS This study includes 420 intact fetuses with CNS anomalies terminated at gestational ages 11+ 0 to 33+ 6 over a 30-year period from 1985 to 2014. An ultrasound (US) examination was performed at the National Centre for Fetal Medicine, St. Olavs Hospital, Trondheim. The autopsies were performed at the Department of Pathology at the same hospital or a collaborating hospital. The anomalies were subcategorized according to the classification by the World Health Organization. RESULTS Neural tube defects such as anencephaly (22.4%, 107/477) and spina bifida (22.2%, 106/477) constituted the most common CNS anomalies, followed by congenital hydrocephalus (17.8%, 85/477). In total, the karyotype was abnormal in 21.0% of all termination of pregnancies (TOPs), with trisomy 18 as the most frequent abnormal karyotype. CHDs, skeletal anomalies, and urinary anomalies were the most common associated organ anomalies. Throughout the study period, there was full agreement between US and postmortem findings of CNS anomalies in 96.9% (407/420) of TOPs. CONCLUSION In this study of autopsy findings of CNS anomalies in intact fetuses terminated after prenatal US diagnosis, neural tube defects were most common. About half of the fetuses had isolated serious CNS anomalies, while the other half were CNS anomalies associated with structural and/or chromosomal anomalies. The prenatal US diagnoses were in good concordance with autopsy findings. In particular, due to challenges of diagnoses made early in pregnancy, it is necessary to continue the validation practice.

Abstract
BACKGROUND Placental pathology in fetal congenital anomalies in second half of pregnancy is largely unknown. METHODS Twenty-six clinical and 45 independent placental phenotypes from pregnancies ≥20 weeks of gestation with congenital anomalies divided into 4 groups were retrospectively compared with analysis of variance or χ 2 with 3 degrees of freedom and with Bonferroni correction for multiple comparisons: group 1 : 112 cases with heart malformations (with or without chromosomal anomalies), group 2 : 41 cases with abnormal karyotypes and anomalies other than heart malformations, group 3 : 87 cases with intrathoracic or intraabdominal mass-forming anomalies (mostly congenital diaphragmatic hernias and adenomatoid airway malformation), and group 4 : 291 miscellaneous cases with mostly skeletal, renal, and central nervous system anomalies not fulfilling the criteria of inclusion into groups 1 to 3. RESULTS Eight of 26 clinical (30.8%) and 16 of 45 (35.5%) placental phenotypes varied statistically significantly among the 4 groups (P < .05), of those, 7 (26.9%) and 4 (8.9%), respectively, remained statistically significant after Bonferroni correction (P Bonferroni ≤ .002). Those placental phenotypes were placental weight, chorionic disc chorionic microcysts, fetal vascular ectasia, and luminal vascular abnormalities of chorionic villi. CONCLUSIONS Fetal anomalies in second half of pregnancy feature abnormal clinical phenotypes much more frequently than abnormal placental phenotypes. Chromosomal abnormalities with or without heart malformations tend to feature villous edema, and erythroblastosis of fetal blood, likely due to fetal heart failure. Mass-forming fetal anomalies feature placental histological lesions of shallow placental implantation, diffuse chronic hypoxic patterns of placental injury, and lesions of fetal vascular malperfusion, likely stasis-induced.

Abstract
OBJECTIVE To review the information on fetal and perinatal autopsies, the process of obtaining consent, and the alternative information-gathering options following a prenatal diagnosis of non-chromosomal anomalies in order to assist health care providers in providing postnatal counselling regarding diagnosis and potential recurrence risks. OUTCOMES To provide better counselling about fetal and perinatal autopsies for women and families who are dealing with a prenatally diagnosed non-chromosomal fetal anomaly. EVIDENCE Published literature was retrieved through searches of PubMed or Medline, CINAHL, and The Cochrane Library in 2010, 2011, and 2017, using appropriate key words (fetal autopsy postmortem, autopsy, perinatal postmortem examination, autopsy protocol, postmortem magnetic resonance imaging, autopsy consent, tissue retention, autopsy evaluation). Results were restricted to systematic reviews, randomized controlled trials/controlled clinical trials, and observational studies. Additional publications were identified from the bibliographies of these articles. There were no date or language restrictions. Grey (unpublished) literature was identified through searching the websites of health technology assessment and health technology assessment-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies. BENEFITS, HARMS, AND COSTS This update educates readers about (1) the benefits of a fetal perinatal autopsy, (2) the consent process, and (3) the alternatives when the family declines autopsy. It also highlights the need for a standardized approach to fetal and perinatal autopsies, emphasizing pertinent additional sampling when indicated. The authors recognize that there is variability across Canada in access to the cited services and resources. As such, these recommendations were developed in an attempt to promote access and to provide a minimum standard for all provinces and territories across the country. VALUES The quality of evidence was rated using the criteria described in the Report of the Canadian Task Force on Preventive Health Care (Table). RECOMMENDATIONS

Abstract
BACKGROUND The prevalence of congenital abnormalities in general populations is approximately 3-5%. One of the most important applications of obstetric ultrasound is in detection of fetal structural defects. OBJECTIVE To assess fetal structural anomalies diagnosed using ultrasound in the three trimesters of pregnancy. DESIGN AND SETTING Retrospective cohort study at the Mário Palmério University Hospital of the University of Uberaba (Universidade de Uberaba, UNIUBE), from March 2014 to December 2016. METHODS Ultrasound data at gestational weeks 11-13 + 6, 20-24 and 32-36 were recorded to identify fetal anomalies in each trimester and in the postnatal period. The primary outcome measurements were sensitivity, specificity, positive predictive value and negative predictive value for detection of fetal anomalies and their prevalence. RESULTS The prevalence of anomalies detected using ultrasound was 2.95% in the prenatal period and 7.24% in the postnatal period. The fetal anomalies most frequently diagnosed using ultrasound in the three trimesters were genitourinary tract anomalies, with a prevalence of 27.8%. Cardiac anomalies were diagnosed more often in the postnatal period, accounting for 51.0% of all cases. High specificity, negative predictive value and accuracy of ultrasound were observed in all three trimesters of pregnancy. CONCLUSION Ultrasound is safe and has utility for detecting fetal anomalies that are associated with high rates of morbidity and mortality. However, the low sensitivity of ultrasound for detecting fetal anomalies in unselected populations limits its utility for providing reassurance to examiners and to pregnant women with normal results.

Abstract
Introduction/Purpose There are no large validation trials comparing teleultrasound to on-site ultrasound. We aim to compare the sensitivity and accuracy of teleultrasound and demonstrate that teleultrasound is not inferior to on-site ultrasound in the pre-natal diagnosis of fetal anomalies. Methods All targeted ultrasounds performed between November 2010 and December 2012 were considered. We excluded studies performed at less than 17 weeks' gestation, on multiple gestations and for reasons other than an anatomical survey. Post-natal diagnoses were obtained from a state level mandatory birth defects surveillance programme. Descriptive statistics (sensitivity, specificity, positive and negative predictive values and accuracy) were calculated for both groups. A test of non-inferiority was performed, with the non-inferiority difference set at 0.15. Results The teleultrasound and on-site ultrasound groups consisted of 2368 and 3145 studies, respectively. The sensitivity of teleultrasound and on-site ultrasound was 57.46% and 76.57%, and the accuracy was 95.9% and 90.97%, respectively. The observed sensitivity difference was -0.1911. The accuracy, specificity, positive and negative predictive values of teleultrasound are similar to on-site ultrasound. Discussion Teleultrasound is inferior to on-site ultrasound in the detection of fetal anomalies; however, it has improved accuracy, as well as higher negative and positive predictive values. A negative teleultrasound is more likely to identify a non-anomalous fetus, and a positive teleultrasound is more likely to correctly identify an anomalous fetus. Conclusion Teleultrasound has an important role in pre-natal diagnosis for those patients unable or unwilling to travel for an on-site ultrasound.

Abstract
Objective To evaluate the detection rate of severe fetal anomalies at the first-trimester screening (FTS) and, vice versa, to evaluate the follow-up of pathological results at FTS at the time of mid-trimester screening (MTS) and throughout pregnancy and delivery in a partially selected population of low-risk pregnancies. Methods We conducted a prospective study on the detection of severe fetal anomalies at routine FTS in 9891 pregnant women with 10,294 fetuses between 11 + 0 and 13 + 6 weeks of gestation. The findings of FTS were compared to the results of MTS and pregnancy and neonatal outcomes. Only cases with severe fetal anomalies were taken for statistical analysis in this study. Results There were 232 cases of fetal anomaly altogether. At the time of FTS, sonographic anomalies were diagnosed in 113 cases and further ultrasound controls arranged. In four cases, fetal anomaly was not confirmed by MTS; in the remaining 109 cases, the sonographic anomaly seen at FTS was confirmed at MTS and in the course of pregnancy with a resulting sensitivity for fetal malformation at FTS of 47.8%, a specificity of 99.96%, a positive predictive value of 96.5% and a negative predictive value of 98.8%. Conclusion FTS can detect almost half of all severe fetal anomalies at an early stage of pregnancy with positive predictive values of 90% and more. Sensitivities varied depending on the organ system and reached the highest figures for anomalies of the heart, the abdomen, the spine and the skeletal system.

Abstract
OBJECTIVE The purpose of this article was to describe our experience with the prenatal diagnosis of CHD in patients referred to our Fetal Cardiology Unit. METHODS Prospective cohort study of consecutive fetuses referred for advanced fetal echocardiography to our Fetal Cardiology Unit during a 3-year period (September 2015-September 2018). RESULTS Totally 809 fetuses were evaluated, with 1263 fetal advanced echocardiographies performed. Suspected cardiac abnormality was the most common indication for referral (62.2%). Only 7.3% of patients had known morbidities or risk factors for CHD. Mean gestational age at first examination was 25.6 ± 6.4 weeks. A total of 528 (65.3%) fetuses were found to have a cardiac defect: 40.7% had isolated CHD while 24.6% had associated anomalies. The most common defects found were ventricular septal defects (20.3%), followed by conotruncal defects (9.7%), hypoplastic left heart syndrome (9.3%), fetal arrhythmias (8.9%), and venous anomalies (8.7%). 31.6% presented abnormal genetic studies, the most frequent being Down syndrome (23/212, 10.8%), followed by DiGeorge syndrome (11/212, 5.2%). CONCLUSIONS Prenatal screening and diagnosis of CHD in Mexico are feasible, with suspected cardiac abnormality being the main reason for referral to a specialized Fetal Cardiology Unit. Efforts must be made to make screening available to the general population in the first and second trimesters of pregnancy by fetal medicine or trained specialists, in order to identify fetal CHD and offer advanced echocardiography, genetic studies, timely fetal cardiac intervention in selected cases, and delivery in tertiary centers, to improve overall survival.

Abstract
OBJECTIVE Virtual reality (VR) objects of fetal ultrasound volumes have been proposed for teaching and learning diagnostic ultrasound. The aim of this study was to determine if VR objects improve learning efficiency and retention of diagnostic ability in fetal ultrasound. METHODS Medical students and junior doctors were taught normal and abnormal sonographic fetal brain anatomy using conventional means (video lectures and review articles; control group) or additionally with selected VR objects from a novel fetal brain atlas (Pocket Brain, http://pb.fetal.ch; study group). Knowledge, speed of recognition and retention of diagnostic ability were tested in multiple-choice questionnaires 1 and 4 months after teaching, and the results were compared between those taught using conventional means only and those taught using VR objects. RESULTS Participants taught using VR objects answered significantly more questions correctly and solved the tests quicker than those taught using conventional methods only, both 1 and 4 months after teaching. CONCLUSION The use of VR objects in teaching fetal ultrasound significantly improves learning efficiency and knowledge retention. Copyright © 2018 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
PURPOSE Exome sequencing (ES) is an efficient tool to diagnose genetic disorders postnatally. Recent studies show that it may have a considerable diagnostic yield in fetuses with structural anomalies on ultrasound. We report on the clinical impact of the implementation of prenatal ES (pES) for ongoing pregnancies in routine care. METHODS We retrospectively analyzed the impact of pES on pregnancy outcome and pre- or perinatal management in the first 22 patients counseled for pES because of one or more structural anomalies on fetal ultrasound. RESULTS In two cases, a diagnosis was made by chromosomal microarray analysis after ES counseling. The remaining 20 cases were divided in three groups: (1) pES to aid parental decision making (n = 12), (2) pES in the context of late pregnancy termination requests (n = 5), and (3) pES to guide pre- or perinatal management (n = 3). pES had a clinical impact in 75% (9/12), 40% (2/5), and 100% (3/3) respectively, showing an overall clinical impact of pES of 70% (14/20). CONCLUSION We show that clinical implementation of pES is feasible and affects parental decision making or pre- and perinatal management supporting further implementation of ES in the prenatal setting.

Abstract
Introduction Our aim was to investigate the accuracy of postmortem fetal magnetic resonance imaging (MRI) compared with fetal autopsy in second trimester pregnancies terminated due to fetal anomalies. A secondary aim was to compare the MRI evaluations of two senior radiologists. Material and methods This was a prospective study including 34 fetuses from pregnancies terminated in the second trimester due to fetal anomalies. All women accepted a postmortem MRI and an autopsy of the fetus. Two senior radiologists performed independent evaluations of the MRI images. A senior pathologist performed the fetal autopsies. The degree of concordance between the MRI evaluations and the autopsy reports was estimated as well as the consensus between the radiologists. Results Thirty‐four fetuses were evaluated. Sixteen cases were associated with the central nervous system (CNS), five were musculoskeletal, one cardiovascular, one was associated with the urinary tract, and 11 cases had miscellaneous anomalies such as chromosomal aberrations, infections and syndromes. In the 16 cases related to the CNS, both radiologists reported all or some, including the most clinically significant anomalies in 15 (94%; CI 70%‐100%) cases. In the 18 non‐CNS cases, both radiologists reported all or some, including the most clinically significant anomalies in six (33%; CI 5%‐85%) cases. In 21 cases (62%; CI 44%‐78%), both radiologists held opinions that were consistent with the autopsy reports. The degree of agreement between the radiologists was high, with a Cohen's Kappa of 0.87. Conclusions Postmortem fetal MRI can replace autopsy for second trimester fetuses with CNS anomalies. For non‐CNS anomalies, the concordance is lower but postmortem MRI can still be of value when autopsy is not an option.

Abstract
Whole exome sequencing (WES) for prenatal diagnosis has a reported diagnostic yield of 6.2%-57%. Our aim was to identify patients with a high likelihood of genetic diagnosis using WES in cases with fetal ultrasound anomalies. This is a series of five selected cases for prenatal WES at our institution. Pregnant couples were initially identified due to fetal ultrasound anomalies. Candidates for WES for fetal diagnosis had a normal fetal karyotype and negative microarray with at least one of the following: parental consanguinity, large regions of homozygosity on fetal microarray, or high likelihood of single gene disorder based on ultrasound findings. All trios underwent sequencing of parental and fetal samples. WES was diagnostic in four of the five cases (80%). We identified two recessive conditions and two de novo mutations. Four couples consented to secondary findings and in one case, the father was found to have an MSH2 mutation associated with Lynch syndrome. The use of specific selection criteria for WES increased diagnostic yield to 80%. This is higher than previously reported. Wide application of our criteria can help identify those who may benefit most from this testing in prenatal diagnosis.

Abstract
Objectives: To establish the best timing for the realization of first-trimester-morphologic-evaluation, following routine midtrimester fetal-ultrasound-scan-recommendations (RFUSR), by performing exclusive transabdominal exploration, and to determine the sensitivity of the mentioned scan for diagnosis of major structural abnormalities.Method: Prospective observational study with 512 pregnant women with singleton gestations (438 low-risk, 74 high-risk) was conducted. Early fetal morphological evaluation (EFME) is performed in line with RFUSR (18-22 weeks) (ISUOG 2010) and a check-list structured evaluation was followed, between 11-13 + 6 weeks. Its performance is assessed in the correct identification of normal fetal anatomy, and its effectiveness in the detection of structural defectsResults: Five hundred and four pregnant women were evaluated, of which, 58.3% EFME are considered complete fetal anatomical surveys. Complete fetal anatomical surveys scans rise from 23.1% at 11-11 + 6 weeks to 63.8% at 13 + 3-13 weeks, with a clear turning point at 12 + 6-13 + 3 weeks (63.8%) (p < .05). From 12 + 6-13 + 3 weeks only renal (26.3%) and cardiac assessments (31.6%) present an inconclusive evaluation greater than 20%. Body mass index (23.9 versus 29.8) and estimated fetal weight (63 versus 86.7 g) influence EMFE's ability of identifying fetal structures (p < .05). EMFE presents sensitivity for the identification of structural malformations of 83.3% (20/24).Conclusions: From 12 + 6 weeks of gestation onwards, a complete fetal morphological evaluation can be performed in 63.8% of cases following the routine midtrimester fetal ultrasound scan recommendations (ISUOG's 20 weeks scan).

OBJECTIVES To assess the performance of first-trimester ultrasound (US) in identifying major fetal structural abnormalities in an unselected population. METHODS We conducted a retrospective analysis of all pregnancies that underwent the 11- to 14-week scan in the Fetal Medicine Department of Filantropia Hospital in Bucharest, which were prospectively examined within our screening program. The purpose of the first-trimester US was to evaluate the risk for chromosomal abnormalities and to conduct fetal anatomic examination using a detailed protocol. RESULTS Our population consisted of 7480 pregnant patients (7576 fetuses). The follow-up was completed for 6045 patients (6114 fetuses). The prevalence of major structural anomalies was 1.89%. In the first trimester, we identified 79% of all major structural anomalies. The highest detection rates were achieved for abdominal wall defects (100%), major central nervous system anomalies (88%), cardiac defects (74%), and skeletal anomalies (71%). The nuchal translucency was increased in 35% of the cases with structural anomalies, and 95% of these were diagnosed in the first trimester. Seventy percent of the patients who presented with structural anomalies and a normal nuchal translucency were diagnosed in the first trimester. CONCLUSIONS Our results emphasize the importance of performing a detailed US examination at 11 to 14 weeks' gestation in identification of fetal structural defects.

Abstract
OBJECTIVES To introduce a new sonographic marker of intrathoracic liver herniation in fetuses with left-sided congenital diaphragmatic hernia (CDH). METHODS In a consecutive series of fetuses with isolated CDH, an ultrasound volume of the fetal abdomen was acquired. On this volume, offline calculation of the angle formed by the midline of the abdomen (joining the center of the vertebral body to the abdominal insertion of the umbilical cord) and a second line joining the center of the vertebral body to the intra-abdominal convexity of the umbilical vein was carried out to give the umbilical vein deviation angle (UVDA). The UVDA was measured in a group of normal fetuses selected as controls. At follow-up, the presence of liver herniation was investigated in all cases of CDH. UVDA values were compared between the CDH group and controls, and between CDH 'liver-up' vs 'liver-down' cases. A receiver-operating characteristics (ROC) curve was constructed to identify a cut-off value of the UVDA with the highest accuracy in predicting liver herniation in the CDH group. RESULTS Between 2009 and 2015, 22 cases of left-sided CDH were included in the study group, of which nine cases had liver herniation. Eighty-eight normal fetuses were recruited as controls. The UVDA was significantly higher in the cases vs controls (15.25 ± 7.91° vs 7.68 ± 1.55°; P < 0.0001). Moreover, the UVDA was significantly increased in CDH fetuses with liver-up vs liver-down (21.77 ± 8.79° vs 10.75 ± 2.10°; P < 0.0001). On ROC curve analysis the UVDA showed good prediction of liver herniation (area under the ROC curve, 0.94; P < 0.0001) with the best cut-off of 15.2°, yielding a sensitivity of 89% and a specificity of 100% (P < 0.0001). CONCLUSIONS In fetuses with CDH, umbilical vein bowing may be quantified by measuring the UVDA using three-dimensional ultrasound. This sonographic marker seems to be an accurate predictor of liver herniation in left-sided CDH. Copyright © 2017 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
Synopsis The establishment of a multidisciplinary consultation system is necessary for the diagnosis of complicated fetal anomalies. Purpose We aimed to investigate the incidences of different types of fetal anomalies and the influence of multidisciplinary consultation on fetal prognosis. Patients and methods Multidisciplinary specialists include obstetricians, pediatricians, pediatric surgeons, and experts of ultrasound department and genetic counseling. Consultation was done if the fetal ultrasound examinations showed abnormality. Follow-up, assistance, and guidance for the fetus were achieved by phone calls. Results Ultrasound screening showed that the incidences of central nervous system anomaly and genitourinary anomaly were 25.80% (275/1,066) and 22.05% (235/1,066), respectively. The detection rates of fetal anomalies were 5.07% (54/1,066), 36.12% (385/1,066), and 58.82% (627/1,066) in pregnant women with gestational age of <20, 20–28, and >28 weeks, respectively. In addition, the fetal cerebral ventriculomegaly accounted for 40.73% of central nervous system malformation, while 71.43% cases with fetal cerebral ventriculomegaly were alleviated during the follow-up period. The proportion of hydronephrosis in genitourinary anomalies was 50.64%, and the remission rate of hydronephrosis was 67.23% during the follow-up period. Conclusion The establishment of a multidisciplinary consultation system is necessary for the diagnosis of complicated fetal anomalies. The central nervous system anomaly and genitourinary anomaly are the most common fetal anomalies. In addition, the remission rates of cerebral ventriculomegaly and fetal hydronephrosis are high during the follow-up period.

Abstract
OBJECTIVES To determine the sensitivity and specificity of first-trimester ultrasound for the detection of fetal abnormalities and to establish which factors might impact on screening performance. METHODS A systematic review and meta-analysis of all relevant publications was performed to assess the diagnostic accuracy of two-dimensional transabdominal and transvaginal ultrasound in the detection of congenital fetal anomalies prior to 14 weeks' gestation. The reference standard was detection of abnormalities at birth or postmortem. Factors that may impact on detection rates were evaluated, including population characteristics, gestational age, healthcare setting, ultrasound modality, use of an anatomical checklist for detection of first-trimester anomalies and type of malformation included in the study. In an effort to reduce the impact of study heterogeneity on the results of the meta-analysis, data from the studies were analyzed within subgroups of major anomalies vs all types of anomaly and low-risk/unselected populations vs high-risk populations. RESULTS An electronic search (until 29 July 2015) identified 2225 relevant citations, from which a total of 30 studies, published between 1991 and 2014, were selected for inclusion. The pooled estimate for the detection of major abnormalities in low-risk or unselected populations (19 studies, 115 731 fetuses) was 46.10% (95% CI, 36.88-55.46%). The detection rate for all abnormalities in low-risk or unselected populations (14 studies, 97 976 fetuses) was 32.35% (95% CI, 22.45-43.12%), whereas in high-risk populations (six studies, 2841 fetuses) it was 61.18% (95% CI, 37.71-82.19%). Of the factors examined for their impact on detection rate, there was a statistically significant relationship (P < 0.0001) between the use of a standardized anatomical protocol during first-trimester anomaly screening and its sensitivity for the detection of fetal anomalies in all subgroups. CONCLUSIONS Detection rates of first-trimester fetal anomalies ranged from 32% in low-risk groups to more than 60% in high-risk groups, demonstrating that first-trimester ultrasound has the potential to identify a large proportion of fetuses affected with structural anomalies. The use of a standardized anatomical protocol improves the sensitivity of first-trimester ultrasound screening for all anomalies and major anomalies in populations of varying risk. The development and introduction of international protocols with standard anatomical views should be undertaken in order to optimize first-trimester anomaly detection. Copyright © 2016 ISUOG.

Abstract
OBJECTIVE To describe the implementation of a nurse-led project to screen parents for depression and traumatic stress in the postpartum period after visiting their newborns in the NICU. DESIGN A standardized universal mental health postpartum screening and referral protocol was developed for parents of high-risk neonates. SETTING/LOCAL PROBLEM The project occurred at the Garbose Family Special Delivery Unit, the world's first obstetrics unit housed within a pediatric hospital serving healthy women who give birth to newborns with prenatally diagnosed fetal anomalies. Parents of neonates admitted to the NICU are at greater risk to develop postpartum psychological distress; therefore, early identification is critical. PATIENTS A total of 1,327 participants were screened, including 725 women who gave birth to live newborns at the Garbose Family Special Delivery Unit and 602 fathers. INTERVENTION/MEASUREMENTS Obstetric nurses asked parents to complete a screening tool that assessed their psychological risk in the postpartum period. A system for mental health triage and referral was available for parents with elevated scores. RESULTS Overall monthly screening procedure compliance rates were high (96.5% mothers and 79.6% fathers). Women (5.5%, n = 40) and men (5.5%, n = 33) showed high risk for traumatic stress, and 35.9% (n = 260) of women and 9.5% (n = 57) of men showed elevated risk for major depression in the imediate postpartum period. CONCLUSION Incorporating the screening process into routine nursing practice with immediate mental health triage and referral made the program feasible. The risk factors identified add to the growing knowledge about parents of newborns in the NICU.

Abstract
OBJECTIVE To assess the natural history and outcome of fetal pulmonary stenosis (PS), particularly that detected at 14-17 weeks' gestation. METHODS In this retrospective study we searched an electronic database of women from the general Israeli population attending a private ultrasound institute (Al-Kol ultrasound institute in Haifa) for routine complete early fetal ultrasound, including all fetal systems and a fetal echocardiogram, between 2004 and 2015. Ninety-seven percent of the women were at low risk of fetal malformations, and 3% had risk factors such as maternal Type-1 diabetes mellitus, exposure during pregnancy to teratogenic drugs, or anomalies in previous pregnancies or in other family members. At presentation at 14-17 weeks of gestation, color and pulsed Doppler imaging were performed across the four cardiac valves. We identified cases in which abnormal flow was detected, leading to suspicion of PS; in these cases, a follow-up examination was carried out at 17-19 weeks and then monthly until delivery or resolution of the finding, and postnatal echocardiography was performed at birth, 4-6 weeks thereafter, and yearly afterwards. Outcome data for suspicious cases, including postnatal diagnosis and general or specific symptoms, were collected by contacting the parents via email or telephone. RESULTS Among 24 185 early prenatal transvaginal ultrasound screening examinations, 23 cases of suspected PS were identified. They were classified into three groups, according to their ultrasound findings. In Group A (n = 8), the ultrasound screen was normal except for high flow velocity across the pulmonary valve. In six cases, this finding had resolved by 20-21 weeks of gestation and all were found to be normal at postnatal follow-up, one case underwent termination of pregnancy at 19 weeks and PS was confirmed at autopsy and one case was lost to follow-up. In Group B (n = 12), there was aliasing across the pulmonary valve. Two of these cases were normal postnatally and eight had mild-to-moderate PS; the remaining two cases developed hypoplastic right ventricle and pulmonary atresia at 19-20 weeks and the pregnancies were terminated. In Group C (n = 3) PS was associated with other anomalies; all three pregnancies were terminated. There were an additional six cases (Group D) not identified in early gestation, in which PS was late-onset. One had tricuspid regurgitation at the early screen, but was subsequently diagnosed with Ebstein's anomaly and pulmonary atresia, at 22 weeks, and was terminated. The other cases had completely normal early ultrasound screening examinations: one case had Ebstein's anomaly and PS was diagnosed at birth; four had isolated mild PS, of which one was diagnosed at 22 weeks' gestation and the other three were diagnosed postnatally, before 3 months of age. The sensitivity for detection of the ascertained cases of PS was 64% (11/17) and the specificity was > 99%. CONCLUSION There is a diverse spectrum of presentation of fetal PS in the early mid-trimester. A possible explanation for this could be different pathophysiological pathways. Further study is needed to explain the different prenatal sonographic presentations in an unselected population. Copyright © 2016 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
Genetics has made great progress in the past decades, and prenatal diagnosis, predictive genetic testing, and genetic counseling have drawn the limelight of public attention. Because the subject of genetic counseling is of crucial consequence for both the short and long term, its ethical aspects are paramount. The question is whether mankind is mature enough to use this extraordinary knowledge in the right way for the benefit of the society. In the center of ethical questions is the comprehensiveness of information provided to the couples or patients and counseling them about results and making informed educated decisions. In addition, it is crucial how sensitive personal information is treated and whether and how it should be made public.

Abstract
OBJECTIF Offrir des renseignements à jour sur l'utilisation pré et postconceptionnelle d'acide folique par voie orale, avec ou sans supplément de multivitamines / micronutriments, aux fins de la prévention des anomalies du tube neural et d'autres anomalies congénitales. Ces renseignements aideront les médecins, les sages-femmes, les infirmières et les autres professionnels de la santé à contribuer aux efforts de sensibilisation des femmes quant à l'utilisation et aux posologies adéquates de la supplémentation en acide folique / multivitamines, avant et pendant la grossesse. RéSULTATS: La littérature publiée a été récupérée par l'intermédiaire de recherches menées dans PubMed, Medline, CINAHL et la Cochrane Library en janvier 2011 au moyen d'un vocabulaire contrôlé et de mots clés appropriés (p. ex. « folic acid », « prenatal multivitamins », « folate sensitive birth defects », « congenital anomaly risk reduction », « pre-conception counselling »). Les résultats ont été restreints aux analyses systématiques, aux études observationnelles et aux essais comparatifs randomisés / essais cliniques comparatifs publiés en anglais entre 1985 et juin 2014. Les recherches ont été mises à jour de façon régulière et intégrées à la directive clinique jusqu'en juin 2014. La littérature grise (non publiée) a été identifiée par l'intermédiaire de recherches menées dans les sites Web d'organismes s'intéressant à l'évaluation des technologies dans le domaine de la santé et d'organismes connexes, dans des collections de directives cliniques, dans des registres d'essais cliniques, et auprès de sociétés de spécialité médicale nationales et internationales. COûTS, RISQUES ET AVANTAGES: Les coûts financiers sont ceux de la supplémentation quotidienne en vitamines et de la consommation d'un régime alimentaire santé enrichi en folate. Les risques sont ceux qui sont liés à une association signalée entre la supplémentation alimentaire en acide folique et des modifications épigénétiques fœtales / la probabilité accrue d'obtenir une grossesse gémellaire. Ces associations pourraient devoir être prises en considération avant la mise en œuvre d'une supplémentation en acide folique. La supplémentation en acide folique par voie orale (ou l'apport alimentaire en folate combiné à un supplément de multivitamines / micronutriments) a pour avantage de mener à une baisse connexe du taux d'anomalies du tube neural et peut-être même des taux d'autres complications obstétricales et anomalies congénitales particulières. VALEURS La qualité des résultats est évaluée au moyen des critères décrits par le Groupe d'étude canadien sur les soins de santé préventifs (Tableau 1). DéCLARATION SOMMAIRE: RECOMMANDATIONS.

Abstract
OBJECTIVES To estimate the effect of maternal body mass index (BMI) on the completion of fetal anatomic surveys before 20 weeks' estimated gestational age (GA). METHODS We conducted a retrospective cohort study of singletons undergoing standard or detailed anatomic sonographic examinations from 2006 to 2014. Patients were categorized by ranges of BMI. The primary outcomes were completion of standard and detailed anatomic surveys before 20 weeks' estimated GA. The effect of the BMI category was assessed by the χ2 test for trends and analysis of variance. RESULTS Of 15,313 patients, 5917 (38%) were obese, and 1581 (10%) had a BMI of 40 kg/m2 or higher. Standard (P < .01) and detailed (P < .01) surveys were less likely to be completed as the BMI category increased. Suboptimal visualization of the fetal chest (P < .01), abdomen (P < .01), and extremities (P < .01) significantly contributed to the decreased standard survey completion rates. Suboptimal visualization of the fetal head (P < .01) and chest (P < .01) significantly contributed to the decreased detailed survey completion rates. There was no statistically significant difference in the sensitivity of a completed standard or detailed anatomic survey for the detection of fetal anomalies. CONCLUSIONS An increasing BMI category was associated with decreased completion of standard and detailed anatomic surveys by 20 weeks' estimated GA. Strategies to improve early visualization of the fetal head, chest, and abdomen in obese women should be investigated to promote anomaly detection and appropriate counseling.

Abstract
BACKGROUND Data regarding pregnancy outcomes in sickle cell disease are conflicting. Previous studies are limited by small sample size, narrow geographic area, and a wide range of resource availability. OBJECTIVE The purpose of this study was to examine the association between maternal sickle cell disease and adverse pregnancy outcomes in a contemporary North American cohort. STUDY DESIGN We performed a retrospective cohort study of 2,027,323 women with singleton pregnancies delivered in California from 2005-2008. Deliveries at <24 or >42 6/7 weeks of gestation were excluded. Women with sickle cell disease were compared with control subjects. Maternal outcomes of interest included preeclampsia, preterm delivery, placental abruption, oligohydramnios, and cesarean delivery; neonatal outcomes included small for gestational age, anomalies, stillbirth, neonatal death, and infant death. RESULTS The prevalence of sickle cell disease was 0.017%. Compared with control subjects, women with sickle cell disease were more likely to have limited prenatal care (7.4 vs 3.8%; P=.001), underlying chronic hypertension (2.3% vs 1.1%; P=.038), and fetal anomalies (14.0 vs 6.4%; P<.001). The increased odds of fetal anomalies persisted after adjustment for multiple confounders (odds ratio, 1.73; 95% confidence interval, 1.26-2.38). Women with sickle cell disease also had higher odds of severe preeclampsia (odds ratio, 3.75; 95% confidence interval, 2.21-6.38), preterm delivery (odds ratio, 2.50; 95% confidence interval, 1.93-3.21), small for gestational age (odds ratio, 1.96; 95% confidence interval, 1.18-3.25), and cesarean delivery (odds ratio, 1.93; 95% confidence interval, 1.40-2.67). CONCLUSION Women with sickle cell disease are at high risk of maternal and neonatal morbidity. Low rates of fetal and neonatal death may reflect improved antenatal surveillance and management as compared with previous studies. The association between sickle cell disease and fetal anomalies warrants further investigation.
