Type 1 diabetes (T1D) during pregnancy possibly affects the development of the thymus and the maturation of the immune system in the offspring. The aim of the ImmunDiabRisk study was to investigate thymus growth and maternal and fetal immune responses in pregnancies with and without T1D. The thymus circumferences of the fetuses of pregnant women with T1D (n=49) and without diabetes (n=59) were measured using ultrasound around the 29th gestational week and standardized for gestational age. Simultaneously, the frequencies and total numbers of cell markers were analyzed by flow cytometry in maternal peripheral blood, and at birth in umbilical cord blood...

Context: Neonatal hyperthyroidism was first described in 1912 and in 1964 was shown to be linked to transplacental passage of maternal antibodies. Few multicenter studies have described the perinatal factors leading to fetal and neonatal dysthyroidism. Objective: To show how fetal dysthyroidism (FD) and neonatal dysthyroidism (ND) can be predicted from perinatal variables, in particular, the levels of anti-thyrotropin receptor antibodies (TRAbs) circulating in the mother and child...

OBJECTIVE: Several studies have highlighted the negative impact of maternal obesity on ultrasound accuracy for fetal weight estimation (EFW). However, the evidence is conflicting. We aimed in our study to find if the ultrasound accuracy for fetal weight estimation would differ or decrease in obese and morbid obesity classes. In addition to study the mode of delivery within the same cohort. METHODS: It's a retrospective study of obese patients with recorded BMI ≥ 30 kg/m(2), class I and II (BMI 30-39...

REVIEW
Sarah Harris, Dallas Reed, Neeta L Vora
Screening for fetal chromosomal disorders has evolved greatly over the last four decades. Initially, only maternal age-related risks of aneuploidy were provided to patients. This was followed by screening with maternal serum analytes and ultrasound markers, followed by the introduction and rapid uptake of maternal plasma cell-free DNA-based screening. Studies continue to demonstrate that cfDNA screening for common aneuploidies has impressive detection rates with low false-positive rates. The technology continues to push the boundaries of prenatal screening as it is now possible to screen for less common aneuploidies and subchromosomal disorders...

BACKGROUND: Common fetal aneuploidies include Down syndrome (trisomy 21 or T21), Edward syndrome (trisomy 18 or T18), Patau syndrome (trisomy 13 or T13), Turner syndrome (45,X), Klinefelter syndrome (47,XXY), Triple X syndrome (47,XXX) and 47,XYY syndrome (47,XYY). Prenatal screening for fetal aneuploidies is standard care in many countries, but current biochemical and ultrasound tests have high false negative and false positive rates. The discovery of fetal circulating cell-free DNA (ccfDNA) in maternal blood offers the potential for genomics-based non-invasive prenatal testing (gNIPT) as a more accurate screening method...

This series and literature review aimed to prenatally characterize the nature of axillary lymphangioma. A total of 30 cases, including our 5 cases, were analyzed. Insights gained from this review are as follows: Septate and nonseptate cysts seem to be different entities. The nonseptate type tends to be small and transient but more highly associated with aneuploidies. Septate cysts are very rarely associated with other abnormalities and hydrops fetalis, unlike cystic hygroma colli, but are more progressive with gestational age and associated with adverse outcomes...
