Fetal Cranial Biometric Abnormalities: The Value of Routine Ultrasound for Early Diagnosis of Glutaric Acidemia Type 1

May 10, 2026

The authors aimed to evaluate the potential of routine fetal ultrasound findings as early indicators of glutaric acidemia type 1 (GA-1). Their study revealed that specific cranial abnormalities, particularly macrocephaly, along with other features like Sylvian fissure widening, may serve as critical early clues for diagnosing GA-1. This recognition could lead to earlier identification and intervention for affected infants.

Neuroimaging Findings and Risk Factors for Brain Injury in Foetuses Treated for Anaemia

May 10, 2026

The authors aimed to characterize neuroimaging findings and identify risk factors for brain injury in foetuses treated for anaemia through intrauterine transfusion. In their study of 93 eligible foetuses, they found that 52% exhibited brain injuries, with male sex being a significant independent risk factor. The results highlight the need for further research to establish standardized imaging protocols and identify at-risk subgroups for better surveillance.

Deep Learning-Based Segmentation of Fetal Anatomical Structures in the First Trimester

May 6, 2026

The authors aimed to develop and evaluate an AI system for the automatic identification and classification of fetal anatomical structures during the first trimester using ultrasound images. Their results showed that the YOLACT model achieved a high anatomical detection accuracy of 98.4% and demonstrated effective real-time processing capabilities, indicating its potential for clinical use in early anomaly screening.

The Utilisation of Genetic Counselling Services Amongst Prenatal Healthcare Providers in Gauteng, South Africa

May 3, 2026

The authors aimed to assess the utilization and perceptions of genetic counselling services among prenatal healthcare providers in Gauteng, South Africa. Their findings indicate that while a majority of providers can refer patients for genetic counselling, actual utilization is low, with significant gaps in knowledge regarding referral indications and the role of genetic counsellors. The study highlights the need for improved education and clearer referral guidelines to enhance access to genetic counselling services in the region.

Transforming Prenatal Care in a Highly Inbred Population: Impact of a Multidisciplinary Board

May 3, 2026

This study investigates the effectiveness of a new prenatal diagnosis (PND) initiative aimed at improving healthcare delivery in a highly consanguineous population in Saudi Arabia. By implementing a structured checklist and a dedicated prenatal board, the initiative successfully enhanced patient safety, reduced errors, and improved the interpretation of genetic variants, ultimately leading to better patient outcomes. The findings suggest that this model could serve as a cost-effective and replicable framework for preventing genetic diseases in similar populations worldwide.

Prenatal Diagnosis of Neurofibromatosis Type 1: No Specific Prenatal Features Observed in Sporadic Fetal Presentations

Apr 29, 2026

The authors aimed to evaluate the indications for prenatal diagnosis (PND) of neurofibromatosis type 1 (NF1) in a Chinese referral medical center over a seven-year period. They found that NF1 does not present specific prenatal features, as most sporadic cases were diagnosed incidentally through advanced genetic testing rather than through parental carrier status. The study identified a variety of NF1 variants, highlighting the complexity of prenatal diagnosis in these cases.

Foetal Persistent Left Superior Vena Cava-Not Always a Benign Finding?

Apr 26, 2026

The authors aimed to assess the prevalence of extra-cardiac anomalies and genetic variations in foetuses diagnosed with persistent left superior vena cava (PLSVC) alongside a structurally normal heart. Their findings revealed that 25% of the cases had associated structural anomalies and 9.5% had genetic abnormalities, suggesting that PLSVC may not be a benign finding and highlighting the need for thorough anatomical assessments and potential genetic testing in affected foetuses.

Cardiac Function in Fetal Growth Restriction: A Systematic Review and Meta-Analysis

Apr 23, 2026

The authors aimed to compare cardiac function in fetuses with fetal growth restriction (FGR) to those without it. Their systematic review and meta-analysis of 15 studies revealed that fetuses with FGR exhibited significant alterations in cardiac geometry and function, including smaller sphericity indices and reduced myocardial performance, while certain measures of cardiac output remained unchanged. Overall, the findings suggest that FGR is associated with notable cardiac changes that could impact fetal health.

Fetal Fraction and Uterine Leiomyoma Volume: New Insights From Interpretable Modeling

Apr 23, 2026

The authors aim to develop a predictive model to estimate the likelihood of achieving a sufficient fetal fraction (FF) for non-invasive prenatal testing (NIPT) based on maternal characteristics and uterine leiomyoma volume. Their study finds that uterine leiomyoma volume significantly influences FF levels, with the best-performing model (XGBoost) achieving high prediction accuracy and indicating that reducing leiomyoma volume can improve FF outcomes. This modeling approach may enhance clinical decision-making for managing pregnancies with low FF.

Novel Fetal Embolization Technique via Transcardiac Transarterial Ultrasound- and Fluoroscopy-Guided Endovascular Surgery for Vein of Galen Malformation: Preclinical Study in the Fetal Lamb

Apr 23, 2026

The authors aimed to evaluate the feasibility and safety of a novel prenatal transarterial embolization technique, termed FETTUS, for treating vein of Galen malformation in a preclinical model using fetal lambs. The study demonstrated successful embolization in a majority of cases, with no adverse effects observed, suggesting that FETTUS could be a viable therapeutic option for this condition in humans.
