ORIGINAL ARTICLE: Cervical Length at Mid-Pregnancy and the Risk of Primary Cesarean Delivery
Mercredi 26 Mars 2008 - 06:55 - 7 mois, 4 semaines depuis - Santé - New England Journal of Medicin In this large observational study of primiparous women, the cervical length at mid-pregnancy was an independent predictor of the risk of cesarean section during labor at term and specifically of cesarean section performed for poor progress during labor.

REVIEW ARTICLE: Mechanisms of Disease: Cardiac Plasticity
Mercredi 26 Mars 2008 - 06:55 - 7 mois, 4 semaines depuis - Santé - New England Journal of Medicin This review explains how the heart responds to physiologic or pathologic conditions. Exercise, pregnancy, and postnatal growth cause physiologic growth; neurohumoral activation, hypertension, and myocardial injury cause hypertrophic growth, which increases the risk of heart failure and malignant arrhythmia. Atrophy of the heart can arise from protracted bed rest, prolonged weightlessness, or mechanical unloading with a ventricular assist device. |
