The relationship between an aortic isthmus blood flow velocity index and the postnatal neurodevelopmental status of fetuses with placental circulatory insufficiency.

Objective: The purpose of this study was to evaluate the association between an abnormal aortic isthmus blood flow index and postnatal neurodevelopmental outcome in fetuses with placental circulatory insufficiency. STUDY DESIGN Forty-eight children who were born between 1991 and 1999 were included in this study on the basis of abnormal umbilical artery Doppler velocimetry. Prenatal isthmus blood flow index was obtained by dividing the sum of the systolic and diastolic Doppler blood flow velocity integrals by the systolic blood flow integrals.

Fasting plasma glucose versus glucose challenge test: screening for gestational diabetes and cost effectiveness.

Objective: To compare the performance in screening for gestational carbohydrate intolerance of the 1-h 50-g glucose challenge test (GCT), fasting plasma glucose (FPG) and fasting capillary glucose (FCG).

Design And Methods: FPG and FCG were measured at the same time as the GCT in 188 women. Gestational carbohydrate intolerance was diagnosed according to the Canadian Diabetes Association criteria.
