OBJECTIVE Bacterial colonization of the fetal membranes and its role in pathogenesis of membrane rupture is poorly understood. Prior retrospective work revealed chorion layer thinning in preterm premature rupture of membranes (PPROM) subjects. Our objective was to prospectively examine fetal membrane chorion thinning and to correlate to bacterial presence in PPROM, preterm, and term subjects. ...

Nonlinear time series analysis techniques have been used to analyze physiologic signals such as EEG and heart rate. The authors illustrate the application of dimensional analysis (DA) to assess neonatal sleep states at increasing gestational ages up to full-term age. One hundred and sixteen EEG-polygraphic recordings were performed on 55 neonatal subjects between 28 and 43 weeks gestational age...

Here the histopathology findings of placental infarction associated with late preterm birth are reported. The subject was a male neonate delivered at 34 weeks and 5 days of gestation with a birth weight of ∼2500 g. His mother had been diagnosed with a threatened premature birth at 27 weeks of pregnancy. The size and weight of the placenta was considered appropriate for gestational age. On the c...

BACKGROUND Little is known about the relationship between maternal occupational physical exertion and leisure time physical activity (LTPA) with preterm delivery (PTD) among Thai women, a population that differs in many respects from women in Western countries. OBJECTIVES To evaluate associations of maternal occupational physical exertion and LTPA with PTD in aggregate and in subgroups (i.e.,...

Objective: This updated systematic review and meta-analysis aimed to assess maternal fetal outcomes of pregnancies based on the Institute Medicine (IOM) guidelines gestational weight gain (GWG).
 Methods: PubMED, SCOPUS, EMBASE Web Science were searched up 30th July 2022. All studies evaluating and/or neonatal twin IOM included.
 Results: Twenty two included. Mothers with experiencing...

Preterm birth is defined as delivery at <37 completed weeks of pregnancy (World Health Organization). Spontaneous preterm birth (SPB) includes preterm labor, preterm spontaneous rupture of membranes, preterm premature rupture of membranes (PPROM) and cervical weakness; it does not include indicated preterm delivery for maternal or fetal conditions. Early SPB (<32 weeks' gestation) is associated...

Endothelial cell damage is characteristic for respiratory distress syndrome and development of chronic lung disease. Vascular endothelial growth factor (VEGF) is an endothelial mitogen that takes part in the growth and repair of vascular endothelial cells. We measured VEGF in 189 tracheal aspirate samples (TAF), and in 24 plasma samples from 44 intubated preterm infants (gestational age, 27.3 +...

OBJECTIVE To compare the characteristics of neonatal seizures between preterm and full-term infants in intensive care unit. METHOD A prospective study was developed with 104 high-risk newborn, 30 preterm and 74 full-term infants, with clinical seizures. The dependent variable was gestational age. STATISTICAL ANALYSES Fisher's exact test, odds-ratio and Mann Whitney U test. RESULTS There w...
