The aim of this study is to assess the procedure-to-delivery interval (PDI), the obstetric complications, and the early neonatal outcome in patients that did or did not receive glucocorticosteroids (GCSs) before third-trimester amniocentesis (TTA). A retrospectively analysis of 445 TTA procedures divided into two groups based on the administration (study group = 220 patients) or not (control group = 225 patients) of GCSs before TTA. The PDI was calculated for all patients. Obstetric and neonatal outcomes were compared between the groups. The rate of procedure-associated complications was similar between the groups. The mean PDI was 47.2 ± 16.8 days. The overall incidence of preterm birth was 11.7%; 9% delivered between 34 and 37 weeks and 2.7% between 28 and 34 weeks. Only nine patients (2%) delivered within seven days following TTA. The incidence of respiratory distress syndrome in the study and control groups was 1.8% and 1.3%, p =.71, respectively. There were no significant differences in other neonatal outcomes in term and preterm deliveries between the study and control groups. In the present study, the administration of glucocorticoids prior to TTA did not reduce the rates of neonatal complications, which was similar in both groups and not higher than the general population.

Objectives: To determine the rate of fetal and neonatal brain lesions and define risk factors for such lesions in pregnancies complicated by Twin Anemia Polycythemia Sequence (TAPS).Methods: A retrospective cohort study of monochorionic twin pregnancies which were diagnosed with TAPS in a single tertiary medical center between 2013 and 2021. Pregnancies were followed with fetal brain neurosonogram every 2 weeks and fetal brain MRI (magnetic resonance imaging) was performed when indicated at 28-32 weeks of gestation; post-natal brain imaging included neonatal brain ultrasound. Pregnancies with pre- and post-natal brain lesions were compared to those without such findings.Results: Overall, 23 monochorionic diamniotic pregnancies were diagnosed with TAPS over the study period resulting in perinatal survival of 91.3% (42/46). In 6/23 (26%) pregnancies and 7/46 (15.2%) fetuses pre- or post-natal brain lesions were detected, of whom five were the polycythemic twins and two were the anemic twins. Brain findings included intra-cerebral hemorrhage and ischemic lesions and were diagnosed prenatally in 6/7 (85.7%) cases. No risk factors for severe brain lesions were identified.Conclusions: TAPS may place the fetuses and neonates at increased risk for cerebral injuries. Incorporation of fetal brain imaging protocols may enhance precise prenatal diagnosis and allow for accurate parental counseling and post-natal care. [ABSTRACT FROM AUTHOR]

Objective: Data on the value of exome sequencing in fetuses with no structural anomalies are limited, especially in the early stages of pregnancy and in low risk pregnancies. We investigated the yield of targeted clinical prenatal trio exome sequencing (pES) in pregnancies with and without fetal structural anomalies. Methods: We performed pES in 353 pregnancies: Group 1 included 143 pregnancies with high clinical suspicion for a genetic disease: pregnancies with increased nuchal translucency, ultrasound structural defects, intrauterine growth restriction, polyhydramnios, or effusion/nuchal edema. Group 2 included 210 pregnancies with no notable abnormal fetal ultrasound findings. 2a. Low risk pregnancies with minor ultrasound findings, referred to the geneticist due to mildly increased risk for genetic disease (50); and 2b. Normal pregnancy surveillance (160). Results: Overall, 26 (7.36%) fetal analyses had pathogenic (P)/likely pathogenic (LP) variants. In group 1, 20/143 (13.99%) cases had P/LP variants. In group 2, 6/210 (2.86%) cases were found to have P/LP variants [5/50 in (2a) and 1/160 in (2b)]. Conclusion: These results show a high rate of abnormal findings on pES even in apparently normal pregnancies. Key points: What's already known about this topic? Previous studies demonstrated that exome sequencing contribute a substantial diagnostic information in pregnancies when the fetus present major structural defects and anomalies What does this study add? This study centers around the inclusion of low risk pregnancies; those with minor ultrasound findings and those with normal pregnancy surveillance. Our findings show that exome sequencing among low risk pregnancies contributed significant and important critical diagnostic information [ABSTRACT FROM AUTHOR]

Hysterosalpingo-foam sonography (HyFoSy) is considered an acceptable alternative for hysterosalpingography (HSG). By combining HyFoSy with two and three-dimensional (2D and 3D) ultrasound and hysterosonography, a complete fertility work-up can be done. We aimed to evaluate the value of a combined ultrasound examination for fertility work-up. During the study period 113 women were examined. Five of 113 (4.4%) examinations were abandoned due to intra-uterine adhesions that were detected by hysterosonography, and five (4.4%) were abandoned due to technical difficulties. Of 103 women who had completed the examination, 2D ultrasound revealed six patients with hydrosalpinx (5.8%) and sonographic signs of adenomyosis in 13 (12.6%) patients. By combining 2D ultrasound with hysterosonography, two (1.9%) fibroids that were penetrating the uterine cavity and seven (6.8%) endometrial polyps were detected. HyFoSy showed bilateral patent tubes in 58 patients (56.3%), unilateral tubal occlusion in 29 (28.1%) and bilateral tubal occlusion in 16 (15.5%). This study shows that the 'one-stop shop' examination is feasible. The combined examination had detected 16 pathological findings that would have not been detected by HyFoSy alone. Hence, it should be offered to couples undergoing routine infertility work-up. What is already known on this subject? The accuracy of the HyFoSy alone has been evaluated in different studies, but this presented ultrasound scan is integrating 4 different modalities in one exam (2D scanning of the pelvis, 3D scanning of the uterus, hysterosonography and HyFoSy) and we were able to evaluate the female pelvic organs, including the uterine cavity, the tubes and the ovaries, in order to expand the range of diagnosed pathologies. What do the results of this study add? The concept of 'one-stop shop' for the evaluation of female pelvis in couples suffering from infertility is feasible, has comparable accuracy as HSG for tubal occlusion, and higher detection rate for uterine malformations. What are the implications of these findings for clinical practice and/or further research? We suggest to incorporate this examination in routine fertility work-up. [ABSTRACT FROM AUTHOR]

Background While it is clear that first trimester congenital cytomegalovirus (CMV) infection can lead to serious neonatal and childhood adverse outcome, the extent of the effect of second and third trimester congenital CMV infection is still unclear. Our aim was to study the short- and long-term outcomes following second and third trimester infection and to evaluate the contribution of prenatal imaging in a prospective cohort. Methods We studied pregnant women with primary CMV infection in the second and third trimesters, as diagnosed by well-dated seroconversion, and proof of vertical CMV transmission. All patients underwent serial prenatal ultrasound (US) and most of them fetal magnetic resonance imaging (MRI). Follow-up information was obtained from hospital charts and by telephone interviews with parents. Results Primary CMV infection occurred in 135 patients, 107 and 28 with second and third trimester infection, respectively. The incidence proportion of composite outcome (hearing loss or neurodevelopmental impairment) following second trimester infection was 7% (7/100, after excluding cases that were terminated) with a 3% incidence of partial unilateral sensory neural hearing loss and a 5% incidence of minor neurodevelopmental abnormalities, including slight verbal and motor delay. Following third trimester infection, there was one case of a very mild motor delay. The incidence proportion of abnormal prenatal findings on US or MRI was not significantly correlated to hearing loss or neurodevelopmental abnormalities. Conclusions Second trimester infection is associated with a slight risk of developing mild childhood sequelae, mostly partial unilateral hearing loss, which may develop late in childhood. Prenatal imaging failed to predict the development of childhood adverse outcome. [ABSTRACT FROM AUTHOR]
