Special Issue Information

Dear Colleagues,

This is the second edition of the Special Issue ‘Updates on Prenatal Diagnosis and Maternal Fetal Medicine’ (https://www.mdpi.com/journal/jcm/special_issues/Prenatal_Maternal_Fetal).

Hemolytic disease of the fetus and newborn as well as alloimmunthrombocytopenia in the fetus are important issues in maternofetal medicine. Studies in this domain are continually evolving and the emerging therapeutic options seem promising. Moreover, congenital heart disease is the single most frequent congenital anomaly. The focus of analyses has now shifted from solely diagnostics to the evaluation of myocardial fetal function and transmission into the newborns. We aim to present the recent research works pertaining to these aforemntioned fields in this Special Issue.

Additionally, fetal therapy, with varying techniques, for open spina bifida has been established at distinguished centers. We thus endeavour to highlight the latest research results on indications, and maternal and fetal outcomes in this Speical Issue.

Background: The objective of our study was to assess the prenatal course, associated anomalies and postnatal outcome and the predictive value of various prenatal parameters for survival in prenatally diagnosed cases of truncus arteriosus communis (TAC). Methods: We evaluated cases from four centers between 2008 and 2021. Results: In 37/47 cases (78.7%), classification into a Van Praagh sbtype was possible, most had TAC type A1 (18/37 = 48.6%). In 33/47 (70.2%) with available valve details on common trunk valve, most presented with tricuspid valves (13/33 = 39.4%). In the overall sample, 14/47 (29.8%) had relevant insufficiency, and 8/47 (17%) had stenosis. In total, 37/47 (78.7%) underwent karyotyping, with 15/37 (40.5%) showing abnormal results, mainly 22q11.2 microdeletion (9/37 = 24.3%). Overall, 17/47 (36.2%) had additional extracardiac anomalies (17/47 = 36.2%). Additional intracardiac anomalies were present in 30/47 (63.8%), or 32/47 (68.1%) if coronary anomalies were included. Four (8.5%) had major defects. Two (4.3%) intrauterine deaths occurred, in 10 (21.3%) cases, the parents opted for termination, predominantly in non-isolated cases (8/10 = 80.0%). A total of 35/47 (74.5%) were born alive at 39 (35–41) weeks. Three (8.6%) pre-surgical deaths occurred in non-isolated cases. In 32/35 (91.4%), correction surgery was performed. The postoperative survival rate was 84.4% (27/32) over a median follow-up of 51.5 months. Initial intervention was performed 16 (1–71) days postpartum, and 22/32 (68.8%) required re-intervention. Regarding prenatal outcome-predicting parameters, no significant differences were identified between the survivor and non-survivor groups. Conclusions: There exist limited outcome data for TAC. To our knowledge, this is the largest multicenter, prenatal cohort with an intention-to-treat survival rate of almost 85%. Full article

Prenatal Exome Sequencing Analysis in Fetuses with Various Ultrasound Findings

Objectives: To evaluate the use of Exome Sequencing (ES) for the detection of genome-wide Copy Number Variants (CNVs) and the frequency of SNVs-InDels in selected genes related to developmental disorders in a cohort of consecutive pregnancies undergoing invasive diagnostic procedures for minor or simple ultrasound findings with no indication of ES. Methods: Women undergoing invasive diagnostic testing (chorionic villus sampling or amniocentesis) for QF-PCR and chromosomal microarray analysis (CMA) due to prenatal ultrasound findings without an indication for ES were selected over a five-month period (May–September 2021). ES was performed to compare the efficiency of genome-wide CNV detection against CMA analysis and to detect monogenic disorders. Virtual gene panels were selected to target genes related to ultrasound findings and bioinformatic analysis was performed, prioritizing variants based on the corresponding HPO terms. The broad Fetal Gene panel for developmental disorders developed by the PAGE group was also included in the analysis. Results: A total of 59 out of 61 women consented to participate in this study. There were 36 isolated major fetal anomalies, 11 aneuploidy markers, 6 minor fetal anomalies, 4 multiple anomalies, and 2 other ultrasound signs. Following QF-PCR analysis, two uncultured samples were excluded from this study, and six (10%) common chromosome aneuploidies were detected. In the remaining 51 cases, no pathogenic CNVs were detected at CMA, nor were any pathogenic variants observed in gene panels only targeting the ultrasound indications. Two (3.9%) monogenic diseases, apparently unrelated to the fetal phenotype, were detected: blepharo-cheilo-odontic syndrome (spina bifida) and Duchenne muscular dystrophy (pyelocaliceal dilation). Conclusions: In our series of pregnancies with ultrasound findings, common aneuploidies were the only chromosomal abnormalities present, which were detected in 10% of cases. ES CNV analysis was concordant with CMA results in all cases. No additional findings were provided by only targeting selected genes based on ultrasound findings. Broadening the analysis to a larger number of genes involved in fetal developmental disorders revealed monogenic diseases in 3.9% of cases, which, although apparently not directly related to the indications, were clinically relevant.

Primary cytomegalovirus (CMV) infection during pregnancy is associated with an increased risk of congenital CMV (cCMV). Hyperimmune globulin (HIG) therapy has been proposed as a potential prophylaxis to reduce maternal–fetal transmission. Data on whether the administration of HIG every 2 weeks offers benefits over HIG administration every 4 weeks are lacking. This was a retrospective analysis including pregnant women with primary CMV infection diagnosed in the first or early second trimester between 2010 and 2022 treated with HIG every 4 weeks (300 IE HIG per kg) or every 2 weeks (200 IE HIG per kg), respectively. In total, 36 women (4 weeks: n = 26; 2 weeks: n = 10) and 39 newborns (4 weeks: n = 29; 2 weeks: n = 10) were included. The median gestational age at the first HIG administration was 13.1 weeks. There was no significant difference in the cCMV rates between the women who received HIG every 4 versus every 2 weeks (n = 8/24 [33.3%] vs. 3/10 [30.0%]; p = 0.850). An abnormal fetal ultrasound was present in three fetuses and fetal magnetic resonance imaging (MRI) anomalies in four fetuses were related to cCMV infection, with no significant difference in the frequency between the two groups. A larger study will be needed to determine whether HIG administration every 2 instead of every 4 weeks improves the maternal–fetal transmission rates. Full article

The detailed sonographic assessment of the fetal neuroanatomy plays a crucial role in prenatal diagnosis, providing valuable insights into timely, well-coordinated fetal brain development and detecting even subtle anomalies that may impact neurodevelopmental outcomes. With recent advancements in artificial intelligence (AI) in general and medical imaging in particular, there has been growing interest in leveraging AI techniques to enhance the accuracy, efficiency, and clinical utility of fetal neurosonography. The paramount objective of this focusing review is to discuss the latest developments in AI applications in this field, focusing on image analysis, the automation of measurements, prediction models of neurodevelopmental outcomes, visualization techniques, and their integration into clinical routine.
