It is now well-established that non-invasive prenatal testing (NIPT), originally designed to screen cell-free DNA (cfDNA) in maternal blood for the presence of common fetal trisomies, can lead to incidental detection of occult maternal malignancies. Retrospective evaluations have demonstrated that the detection of multiple copy number alterations in cfDNA is particularly suggestive of an incipient tumor and that cancer detection rates not only depend on tumor biology but also on applied NIPT technologies and downstream diagnostic investigations. Since the identification of a maternal cancer in pregnancy has implications for both woman and the unborn child, prospective studies are needed to provide evidence on best clinical practices and on clinical utility in terms of patient outcomes.

(1) Background: Fetal chromosomal examination is a critical component of modern prenatal testing. Traditionally, maternal serum biomarkers such as free β-human chorionic gonadotropin (Free β-HCG) and pregnancy-associated plasma protein A (PAPPA) have been employed for screening, achieving a detection rate of approximately 90% for fetuses with Down syndrome, albeit with a false positive rate of 5%. While amniocentesis remains the gold standard for the prenatal diagnosis of chromosomal abnormalities, including Down syndrome and Edwards syndrome, its invasive nature carries a significant risk of complications, such as infection, preterm labor, or miscarriage, occurring at a rate of 7 per 1000 procedures.

Background: Chromosomal numerical and structural alterations are significant causes of various developmental disorders in foetuses. Non-invasive prenatal testing (NIPT) has emerged as an effective screening tool for detecting common aneuploidies, aiding in the identification of individuals who may require further diagnostic work-up.
Methods: This retrospective, monocentric observational study evaluates the usage patterns, test choices, turnaround times (TAT), and outcomes of NIPT between 2013 and 2023 on a sample of 2431 pregnant women at a special hospital offering outpatient services and comprehensive gynaecological/obstetric inpatient care.

Background: Fetal midgut volvulus is a rare disease, with a high risk of potentially life-threatening fetal complications.
Purpose: The aim of this study was to retrospectively analyze the imaging findings of fetal midgut volvulus diagnosed by magnetic resonance imaging (MRI) and explore its value in non-invasive prenatal diagnosis.
Methods: A retrospective collection of data from 156 fetuses suspected of intestinal obstruction by ultrasound examination in our hospital was conducted.

Objective: Advancements in non-invasive prenatal screening (NIPS) could significantly alter prenatal screening by expanding the range of genetic conditions screened. This study aims to explore the perspectives of healthcare professionals (HCP) on the expanded use of NIPS and explore specifications for the inclusion of genetic conditions.
Method: Semi-structured interviews were conducted with Canadian HCPs who counsel pregnant individuals about NIPS.

Introduction: Genome-wide non-invasive prenatal testing (gwNIPT) has screening limitations for detectable genetic conditions and cannot detect microdeletions/microduplications (MD) or triploidy. Nuchal translucency (NT) increases with gestation and with genetic or structural abnormalities. This study aims to determine the utility of NT measurement in detecting genetic abnormalities not identified by gwNIPT and the optimal NT threshold value.
