BACKGROUND Trisomies 13, 18, and 21 account for the majority of chromosomal aneuploidies detected in prenatal diagnosis. Diagnosis of these trisomies relies mainly on karyotype analysis. Several molecular methods have been developed for trisomy detection, but performance or throughput limitations of these methods currently constrain their use in routine testing. METHODS We developed multiplex...
BACKGROUND Trisomy 18, the second most common autosomal trisomy, has the highest incidence of congenital heart disease of all chromosomal abnormalities. This study assessed the use of nuchal translucency (NT) measurement and fetal echocardiography at 16 to 18 weeks of gestation in prenatal detection for trisomy 18. METHODS Screening for chromosomal aneuploidy using fetal NT measurement was pe...
OBJECTIVE We investigated whether the concentration of the glycoprotein fetuin A is altered in the second trimester amniotic fluid of trisomy 21 pregnancies compared with euploid pregnancies. METHODS 25 pregnancies with an extra chromosome 21 were matched for maternal and gestational age with 25 pregnancies with normal karyotype. Levels of fetuin A in amniotic fluid were measured by a commerc...
This paper empirically assesses the relative role of health plan prices, service quality and optional benefi ts in the decision to choose a health plan. We link representative German SOEP panel data from 2007 to 2010 to (i) health plan service quality indicators, (ii) measures of voluntary benefi t provision on top of federally mandated benefi ts, and (iii) health plan prices for almost all Ger...
