Labor estimation by informational objective assessment (LEIOA) for preterm delivery prediction.

Purpose: To introduce LEIOA, a new screening method to forecast which patients admitted to the hospital because of suspected threatened premature delivery will give birth in < 7 days, so that it can be used to assist in the prognosis and treatment jointly with other clinical tools.

Methods: From 2010 to 2013, 286 tocographies from women with gestational ages comprehended between 24 and 37 weeks were collected and studied. Then, we developed a new predictive model based on uterine contractions which combine the Generalized Hurst Exponent and the Approximate Entropy by logistic regression (LEIOA model).

Estimation of preterm labor immediacy by nonlinear methods.

Preterm delivery affects about one tenth of human births and is associated with an increased perinatal morbimortality as well as with remarkable costs. Even if there are a number of predictors and markers of preterm delivery, none of them has a high accuracy. In order to find quantitative indicators of the immediacy of labor, 142 cardiotocographies (CTG) recorded from women consulting because of suspected threatened premature delivery with gestational ages comprehended between 24 and 35 weeks were collected and analyzed.

Induction of labor in breech presentation at term: a retrospective cohort study.

Objective: To compare the outcome of two methods of labor induction and spontaneous onset of labor in breech presentation at term.

Material: A retrospective study between 2003 and 2012. We compare obstetric (indication of induction, Bishop score, cesarean rate) and perinatal outcomes (Apgar score, umbilical artery pH, base excess ≤-12 mmol/L, admission to neonatal unit) between prostaglandins and oxytocin.
