Lessons learned from 5 years of newborn screening for congenital adrenal hyperplasia in the Czech Republic: 17-hydroxyprogesterone, genotypes, and screening performance.

The aims were to summarize the experience and to determine the performance metrics of newborn screening (NBS) for congenital adrenal hyperplasia (CAH) in the Czech Republic. 17-Hydroxyprogesterone (17OHP) was measured in NBS samples prospectively in 545,026 newborns and retrospectively in 31 CAH patients born outside the study period. A total of 2,811 screened newborns had abnormal 17OHP; CAH was confirmed in 46 probands.

Diurnal variation of soluble E- and P-selectin, and intercellular adhesion molecule-1 in patients with and without coronary artery disease.

Background: The more frequent onset of acute coronary syndromes (ACS) in the morning has been known for a long time. Diurnal changes of fibrinolysis such as lower activity of tissue plasminogen activator and higher activity of plasminogen activator inhibitor-1 (PAI-1) in the morning has been demonstrated previously and correspond with the manifestation of ACS. Less is known about the diurnal variation of soluble adhesion molecules as markers of endothelial or platelet activity in patients with coronary artery disease (CAD).
