Ultrasound assessment of maternal adipose tissue during 1st trimester screening for aneuploidies and risk of developing gestational diabetes.

Introduction: The objective of the present study is to compare the sonographic measurement of subcutaneous adipose thickness and visceral adipose thickness during 1st trimester screening for aneuploidies between non-diabetic pregnant women and patients who develop 1st trimester or 2nd trimester gestational diabetes mellitus (GDM).

Material And Methods: Adipose thickness was measured by transabdominal ultrasound imaging in pregnant women attending our clinic for screening for fetal aneuploidies between 11 and 13 weeks of gestation. During the 1st trimester all patients were evaluated for fasting glycemia in accordance with the International Association of Diabetes and Pregnancy Study Groups (IADPSG) recommendations.

First trimester contingent screening for trisomies 21,18,13: is this model cost efficient and feasible in public health system?

Purpose: To evaluate the effectiveness of three different first trimester screening models for trisomies 21, 18 and 13, in terms of detection rate, invasive test rate and final costs.

Material And Methods: We analyzed the distribution of risk for trisomies 21, 18 and 13 in a population of 20,831 singleton pregnancies based on maternal age, fetal heart rate, nuchal translucency, free beta human chorionic gonadotropin and pregnancy-associated plasma protein A (Combined test). On the basis of our data, we estimated the performance and cost of screening for trisomies using three different models at specific cutoffs: Combined test; Cell free DNA test and Contingent screening test.

First trimester fetal anatomy study and identification of major anomalies using 10 standardized scans.

Objective: to validate the use of the first trimester scan not just as a screening tool for chromosomal anomalies, but also as a method to identify the major anatomic anomalies using 10 standardized scans.

Methods: five years of prospective study analyzing the fetal anatomy of 5924 patients with a singleton pregnancy during the first trimester screening for chromosomopathies. A check list of 10 predetermined scans had been used.

Validation of a method for noninvasive prenatal testing for fetal aneuploidies risk and considerations for its introduction in the Public Health System.

Objective: The aim of this study was to validate noninvasive prenatal testing (NIPT) for fetal aneuploidies by whole-genome massively parallel sequencing (MPS).

Methods: MPS was performed on cell-free DNA (cfDNA) isolated from maternal plasma in two groups: a first set of 186 euploid samples and a second set of 195 samples enriched of aneuploid cases (n = 69); digital PCR for fetal fraction (FF) assessment was performed on 178/381 samples. Cases with <10 × 10 reads (n = 54) were excluded for downstream data analysis.

Sonographic diagnosis of fetal cardiac rhabdomyomas and cerebral tubers: a case report of prenatal Tuberous Sclerosis.

Unlabelled: The rhabdomyoma constitutes more than 60% of all cardiac tumors that are diagnosed in the prenatal and postnatal age. In more than 50% of cases, it is the first clinical manifestation of tuberous sclerosis (TS), autosomal dominant genetic condition and multisystem involvement.

Methods: we report a case of cardiac rabdomyomatosis in twin pregnancy bicorial biamniotic, with suspicion for tuberous sclerosis, diagnosed at our hospital.

Satisfactory rate of post-processing visualization of fetal cerebral axial, sagittal, and coronal planes from three-dimensional volumes acquired in routine second trimester ultrasound practice by sonographers of peripheral centers.

Objective: The aim of this study was to evaluate the feasibility to visualize central nervous system (CNS) diagnostic planes from three-dimensional (3D) brain volumes obtained in ultrasound facilities with no specific experience in fetal neurosonography.

Methods: Five sonographers prospectively recorded transabdominal 3D CNS volumes starting from an axial approach on 500 consecutive pregnancies at 19-24 weeks of gestation undergoing routine ultrasound examination. Volumes were sent to the referral center (Department of Obstetrics and Gynecology, Università Roma Tor Vergata, Italy) and two independent reviewers with experience in 3D ultrasound assessed their quality in the display of axial, coronal, and sagittal planes.

Satisfactory rate of postprocessing visualization of standard fetal cardiac views from 4-dimensional cardiac volumes acquired during routine ultrasound practice by experienced sonographers in peripheral centers.

The aim of this study was to evaluate the feasibility of visualizing standard cardiac views from 4-dimensional (4D) cardiac volumes obtained at ultrasound facilities with no specific experience in fetal echocardiography. Five sonographers prospectively recorded 4D cardiac volumes starting from the 4-chamber view on 500 consecutive pregnancies at 19 to 24 weeks' gestation undergoing routine ultrasound examinations (100 pregnancies for each sonographer). Volumes were sent to the referral center, and 2 independent reviewers with experience in 4D fetal echocardiography assessed their quality in the display of the abdominal view, 4-chamber view, left and right ventricular outflow tracts, and 3-vessel and trachea view.
