neonatal morbimortality and heavy costs. Despite the significant medical advances, the rate of prematurity has not declined over the past 40 years and even continues to rise in the developed countries. In order to decrease the prematurity is necessary that two premises: to identify the pregnant women at risk of preterm birth, and dispose of useful measures aimed at prolonging the pregnancy and therefore avoid preterm delivery. The investigators propose a clinical trial with the objective to identify effective strategies to reduce the premature birth (34 weeks and earlier) rate in the population of pregnant women at risk for premature birth, which will be identified by ultrasound during the second trimester of their pregnancy.\n\nThe investigators intend to compare two accepted strategies: administration of progesterone (vaginally) or the placement of vaginal pessaries. These 2 strategies are affordable, easy to apply, and they present very few maternal-fetal secondary effects.",[289],"Early Onset of Delivery Before 37 Weeks","COMPLETED","2016-10-14",{"date":293,"type":294},"2016-10-17","ESTIMATED",{"date":296,"type":24},"2012-08",{"date":298,"type":283},"2016-04",{"name":270,"class":6},27]
