To assess long-term neurodevelopmental outcomes in children after radiofrequency ablation (RFA) for twin reversed arterial perfusion (TRAP) sequence.

Neurodevelopmental delay is more common in children born with congenital heart defects (CHD), even with optimal perinatal and peri-operative care. It is hypothesized that fetuses with CHD are prone to neurological impairment in utero due to their cardiac defect, possibly leading to delayed cortical development.

To compare and validate umbilical venous flow volume (UVFV) measured at the intra-abdominal portion using ultrasound with actual flow volume of umbilical vein (UV) in fetal sheep sustained on the EXTrauterine Environment for Neonatal Development (EXTEND) system.

Non-Invasive Prenatal Testing (NIPT) is increasingly being implemented worldwide. In public health programs, equitable access to healthcare is a fundamental principle which also applies to fetal aneuploidy screening. However, the out-of-pocket costs of NIPT may lead to sociodemographic disparities in uptake of screening. This study assessed whether there is a difference in the uptake of NIPT in socioeconomically

Preconception and prenatal carrier screening is designed to provide reproductive risk information, but carriers for some autosomal recessive or X-linked conditions also have personal health risks. This study investigated the prevalence of and inclusion of personal health implications in pre- and post-test counseling.

Cancer is diagnosed in one in 1000 to 1500 pregnancies. Most frequently encountered malignancies during pregnancy are breast cancer, hematological cancer, cervical cancer and malignant melanoma. Maternal cancer is associated with an increased risk of IUGR and preterm labor, especially in patients with systemic disease or those receiving chemotherapy during pregnancy, requiring a high-risk obstetrical

The positive predictive values of cell free DNA (cfDNA) and rates of confined placental mosaicism (CPM), imprinting and other factors vary by chromosome.

Fetal growth restriction (FGR) is a common complication of pregnancy, associated with higher risk of perinatal mortality and adverse health and developmental outcomes for surviving infants. True FGR relates to a pathological restriction of fetal growth resulting from complex interactions between maternal, placental, fetal, and environmental factors. Early-onset FGR (onset <32 weeks' gestation) is often

To identify racial disparities in cell-free fetal DNA (cffDNA) first-line aneuploidy screening use among advanced maternal age women at a safety net hospital.

Low fetal fraction (LFF) in prenatal cell-free DNA (cfDNA) testing is an important cause of test failure and no-call results. LFF might reflect early abnormal placentation and therefore be associated with adverse pregnancy outcome. Here, we review the available literature on the relationship between LFF in cfDNA testing and adverse pregnancy outcome.

Reasons for first trimester noninvasive prenatal screening (NIPS) test failure in obese women remain elusive. As dilution from maternal sources may be explanatory, we determined the relationship between obesity, fetal fraction (FF), and total cell-free DNA (cfDNA) using our NIPS platform.

Lower urinary tract obstruction (LUTO) is a rare but critical fetal diagnosis. Different ultrasound markers have been reported with varying sensitivity and specificity.

Expanded carrier screening (ECS) assesses the risk of individuals and couples of having a child affected with a set of genetic conditions. Carriers have options available to optimize pregnancy outcomes based on personal values and preferences. The greatest range of options is available prior to pregnancy, therefore professional societies recommend this screening be performed preconception. This study

Israel is one of the first countries to incorporate chromosomal microarray analysis into routine prenatal care. We explored attitudes of Israeli healthcare professionals (HCPs) towards the disclosure of challenging findings: variants of uncertain clinical significance (VUS), susceptibility loci (SL) for neurodevelopmental disorders and variants associated with adult-onset (AO) conditions. Particularly

Three decades ago, the observation that first trimester fetuses with excess fluid accumulation at the back of the neck were more likely to be aneuploid, gave rise to a new era of prenatal screening. The nuchal translucency (NT) measurement in combination with serum biomarkers and maternal age, resulted in the first trimester combined screening (FTCS) program. The introduction of noninvasive prenatal

Twin pregnancies are common and associated with pregnancy complications and adverse outcomes. Prenatal clinical management is intensive and has been hampered by inferior screening and less acceptable invasive testing. For aneuploidy screening, meta-analyses show that non-invasive prenatal testing (NIPT) through analysis of cell-free DNA (cf-DNA) is superior to serum and ultrasound-based tests. The
