OBJECTIVE: Prenatal screening for trisomy 21 is a standard of care. Emerging cell-free fetal DNA (cffDNA) technologies can improve screening performance, but they are expensive. This study was conducted to propose a contingent screening model that would incorporate cffDNA technology, would remain affordable, and could be applied equitably in a publically funded system. METHODS: Using performance and cost parameters from published literature, four prenatal screening strategies were compared...

BACKGROUND: In New Zealand (NZ), Maori and Pacific women are less likely to complete prenatal screening for Down's syndrome and other aneuploidies than other ethnic groups. Young women <20 have low rates of completed screening compared with women >20 years. Women living in deprived areas have lower completed screen rates than women living in more affluent areas. Combined first trimester screening has a superior sensitivity (85%) compared with second trimester screening (75%) for trisomy 21...

OBJECTIVE: To determine the performance of a five (5) serum marker plus ultrasound screening protocol for T21, T18 and T13. METHOD: Specimens from 331 unaffected, 34 T21, 19 T18 and 8 T13 cases were analyzed for free Beta hCG, PAPP-A, AFP, PlGF and dimeric inhibin A (DIA). Gaussian distributions of MoM values were used to estimate modeled false positive and detection rates. RESULTS: For T21, at a 1/300 risk cut-off, detection rate of screening with all five serum markers along with nuchal translucency and nasal bone was 98% at a 1...

Accurate and timely prenatal diagnosis of spina bifida (SB) is a major goal of modern antenatal care. Prenatal screening for open SB should be first performed at the time of routine first-trimester ultrasound by examining the posterior fossa for obliteration or non-visualization of the fourth ventricle ("intracranial translucency") and cisterna magna. The second step of screening is the second-trimester anatomy scan, at which time the features of the Chiari type II malformation should be looked for, including ventriculomegaly, scalloping of the frontal bones ("lemon" sign), and backward and caudal displacement of the cerebellar vermis with obliteration of the cisterna magna ("banana" sign)...

BACKGROUND: Monochorionic twin pregnancies are at increased risk of complications due to sharing a single placenta and potentially developing unbalanced vascular anastomoses. Complications include twin-twin transfusion syndrome (TTTS) which affects 10-15% monochorionic twins, and if untreated has a 70-90% perinatal loss rate. We are currently unable to predict which twins will develop complications or to what severity. We have previously shown differences in angiogenic and placental growth factors in maternal blood in pregnancies complicated by TTTS compared to twin pregnancies not complicated by TTTS but matched for gestation...
