Low cardiac output measured by bioreactance and adverse outcome in preterm infants with birth weight less than 1250 g.

Background: Recently a new continuous non-invasive cardiac output measurement, bioreactance, has become available. Bioreactance measurement of cardiac output has been shown to correlate with left ventricular output detected by echocardiography in healthy term and preterm neonates.

Aims: Our aim was to correlate cardiac output measurements by bioreactance in the first 48 h of life with adverse outcomes attributable to hypoperfusion (peri/intraventricular haemorrhage (PIVH) and/or necrotising enterocolitis (NEC)) in the cohort of extremely preterm infants.

Abdominal visceral adiposity in the first trimester predicts glucose intolerance in later pregnancy.

Objective: To assess whether abdominal adiposity in early pregnancy is associated with a higher risk of glucose intolerance at a later gestational stage.

Research Design And Methods: Subcutaneous and visceral fat was measured with ultrasonography at approximately 12 weeks' gestation. A 50-g glucose challenge test (GCT) was performed between 24 and 28 weeks' gestation.
