Evaluation of four years of prenatal screening for aneuploidies in Hospital S. Francisco Xavier using the integrated test.

We report an audit of our Prenatal Screening Programme for aneuploidies between March 2003 and August 2007. Overall detection and false positive rates were 86% and 3.6%, respectively.

Comparative value of BNP and NT-proBNP in diagnosis of heart failure.

Brain natriuretic peptide (BNP) and the N-terminal portion of proBNP (NT-proBNP) have emerged as excellent diagnostic biohumoral indicators in cardiac disease. It is not clear which of the two is superior as a diagnostic marker in HF.
