BACKGROUND Preterm birth is a leading cause of perinatal morbidity and mortality worldwide, resulting in a pressing need to identify risk factors leading to effective interventions. Limited evidence suggests potential relationships between maternal sleep or vital exhaustion and preterm birth, yet the literature is generally inconclusive. METHODS We examined the relationship between maternal s...

In this paper we study breakage rate statistics of small colloidal aggregates in nonhomogeneous anisotropic turbulence. We use pseudospectral direct numerical simulation of turbulent channel flow and Lagrangian tracking to follow the motion of the aggregates, modeled as sub-Kolmogorov massless particles. We focus specifically on the effects produced by ductile rupture: This rupture is initially...

The follow-up of premature rupture of membranes requires an hospitalization. The aim of this work was to evaluate the interest of the Prom-Test in the action to be taken in the case of a suspicion of premature rupture of membranes, a negative result allowing to not hospitalize the patient. 105 tests have been carried out producing 73 negative results, 23 positive and 9 doubtful. The childbirth,...

To date, the parameters that determine the rupture area of great subduction zone earthquakes remain contentious. On 1 April 2014, the Mw 8.1 Iquique earthquake ruptured a portion of the well-recognized northern Chile seismic gap but left large highly coupled areas un-ruptured. Marine seismic reflection and swath bathymetric data indicate that structural variations in the subducting Nazca Plate ...

The optimal management of preterm premature rupture of membranes (PROM) is controversial. Maternal risks must be weighed against fetal benefit when expectant management is considered. Despite concerns about maternal harm, protocols of expectant management seem to afford the best perinatal outcomes. Given that infection often is the common pathway for delivery in preterm PROM, recent reports hav...

BACKGROUND Amniocentesis is the accepted mode of attaining amniotic fluid to perform tests for fetal lung maturity. The purpose of this study was to validate a non-invasive fetal lung maturity test by counting lamellar bodies from a vaginal pool among women with preterm premature rupture of membranes. METHODS In a prospective study, amniotic fluid specimens were collected from a vaginal pool ...

BACKGROUND To evaluate the influence of microbial invasion of the amniotic cavity (MIAC) and histological chorioamnionitis (HCA) on the magnitude of intra-amniotic inflammatory response in preterm prelabor rupture of membranes (PPROM). METHODOLOGY/PRINCIPAL FINDING A prospective cohort study was performed in 107 women with PPROM between 23.0 and 36.6 weeks of gestational age. Twenty-six prote...

Recent studies in animals have suggested that antenatally administered steroids may accelerate fetal lung maturation and prevent the development of respiratory distress following premature delivery [7, 13, 16, 18, 21, 23]. Further studies in human pregnancies complicated by premature rupture of the amniotic membranes [l, 3, 4,19, 24], in trauterine growth retardation [6], or maternal heroin add...

OBJECTIVES Preterm premature rupture of membranes (PPROM) is among the most important causes of perinatal morbidity and mortality. The aim of this study is to survey the pregnancy outcomes in preterm premature rupture of membranes with an amniotic fluid index of <5 and >5. METHODS This prospective cohort study was performed on 137 pregnant women complicated by preterm premature rupture of mem...

Objectives: To study cervical colonization in women with premature rupture of membranes and the influence of infection on preterm newborns. Methods: Prospective analysis. Results: 167 (38.66%) from 432 preterm deliveries were complicated with premature prelabour rupture of the membranes (PPROM). Organisms which induce chorioamnionitis and newborns infections mostly belong to group B streptococc...
