BACKGROUND: Preterm premature rupture of membrane (PPROM) can lead to serious consequences such as intrauterine infection, prolapse of the umbilical cord, and neonatal respiratory distress syndrome. Genital infection is a very important risk which closely related with PPROM. The preliminary study only made qualitative research on genital infection, but there was no deep and clear judgment about the effects of pathogenic bacteria. This study was to analyze the association of infections with PPROM in pregnant women in Shaanxi, China, and to establish Bayesian stepwise discriminant analysis to predict the incidence of PPROM...

An all-atom phospholipid bilayer and triblock copolymer model was developed for Molecular Dynamics (MD) studies. These were performed to investigate the mechanism of interaction between membrane stabilizing triblock copolymer P188 and 1-palmitoyl-2-oleoyl-sn- glycero-3-phosphatidylcholine (POPC) lipid bilayers under applied lateral surface tension (γ) to model membrane mechanical stress. Results showed that P188 insertion is driven by the hydrophobic polypropylene oxide (PPO) core and dependent on bilayer area per lipid...

OBJECTIVE: Human milk (donor milk (DM) and/or maternal milk (MM)) feedings protect against late onset sepsis (LOS), necrotizing enterocolitis (NEC) and death. However, DM lacks many anti-infective components of MM. Therefore, we studied exclusive MM feedings to evaluate the full effect of human milk on infectious and other outcomes in premature infants. STUDY DESIGN: All infants born before 33 weeks postmenstrual age (PMA) who received exclusive (>95%) MM or exclusive preterm formula (PF) were included in this prospective investigation...

BACKGROUND: Therapy with inhaled nitric oxide (iNO) is effective in the management of pulmonary hypertension and severe hypoxemia. However, these benefits have not been demonstrated in preterm infants (<34 weeks). The objective of this report is to present the experience of eight cases of preterm neonates with respiratory distress syndrome (RDS) and refractory hypoxemia, with oligohydramnios history. METHODS: We evaluated the clinical feature of 8 preterm neonates with severe hypoxemia who had maternal antecedents of oligoamnios, mainly due to premature rupture of membranes...

Preterm birth continues to be a significant public health problem. Infection (bacterial and or viral) and inflammation, by stimulating proinflammatory cytokines, adhesion molecules, and matrix metalloproteinase 9 (MMP9), play a central role in the rupture of membranes and myometrial contractions. SMAD7 has been implicated in regulating the inflammatory response; however, no studies have been performed with regard to human labor. In this study, we determined the effect of spontaneous human labor and prolabor mediators on SMAD7 expression in myometrium and fetal membranes...

Liquid electrolyte-gated organic field effect transistors (EGOFETs) and organic electrochemical transistors (OECTs) have recently emerged as powerful technology platforms for sensing and simulation of living cells and organisms. For such applications, the transistors are operated at a gate voltage around or below 0.3 V because prolonged application of a higher voltage bias can lead to membrane rupturing and cell death. This constraint often prevents the operation of the transistors at their maximum transconductance or most sensitive regime...

Achondroplasia is an autosomal dominant disease which is characterized by limb shortening and narrow trunk, and macrocephaly. Women with achondroplasia suffer from infertility, menorrhagia, dysmenorrhoea, leiomyomata and early menopause. Our case was a 26-year-old woman with achondroplasia who had scoliosis and osteoporosis. She referred to our clinic at 9 weeks of gestation and had all screenings completely. She had a single female fetus with no abnormalities. She had an emergent due to rupture of membranes at 37 weeks and 3 days under general anesthesia...

Thallium (Tl) is a well-recognized hazardous toxic heavy metal that has been reported to have embryotoxicity and fetotoxicity. However, little is known about its association with preterm birth (PTB) in humans. We aimed to evaluate the predictors of Tl exposure and assessed its relation with PTB. The study population included 7173 mother-infant pairs from a birth cohort in Wuhan, China. Predictors of Tl concentrations were explored using linear regression analyses, and associations of Tl exposure with risk of PTB or gestational age at birth were estimated using logistic regression or generalized linear models...

BACKGROUND: The progestogen 17-alpha hydroxyprogesterone caproate is 1 of only 2 agents recommended for clinical use in the prevention of spontaneous preterm delivery, and studies of its efficacy have been conflicting. We have developed an in vitro model to study the fetal membrane weakening process that leads to rupture in preterm premature rupture of the fetal membranes. Inflammation/infection associated with tumor necrosis factor-alpha induction and decidual bleeding/abruption associated thrombin release are leading causes of preterm premature rupture of the fetal membranes...

Preterm premature rupture of membrane (pPROM) is associated with 30-40% of preterm births. Infection is considered a leading cause of pPROM due to increased levels of proinflammatory cytokines in amniotic fluid. Only 30%, however, are positive for microbial organisms by amniotic fluid culture. Interestingly, in some pregnancies complicated by preterm premature rupture of membranes (pPROM), membranes heal spontaneously and pregnancy continues until term. Here, we investigated mechanisms of amnion healing. Using a preclinical mouse model, we found that small ruptures of the fetal membrane closed within 72 h whereas healing of large ruptures was only 40%...

AIM: Iatrogenic premature rupture of membrane (PROM) is one of the major complications related to fetoscopic laser photocoagulation (FLP) for twin-twin transfusion syndrome (TTTS). However, amniotic fluid leakage (AFL) sometimes spontaneously disappears. This study evaluated the incidence and clinical characteristics of transient AFL after FLP. METHODS: We retrospectively reviewed pregnancies that underwent FLP for TTTS at a single center. Patients with apparent AFL within 2 weeks after FLP were divided into two groups: transient AFL, defined by the disappearance of fluid leakage within a week; and PROM, if AFL persisted continuously for more than a week or premature birth occurred, including miscarriage, within a week of the first symptom of AFL...

PURPOSE: Reconstruction of the ruptured interosseous membrane (IOM) is critical to restore forearm stability for the chronic Essex-Lopresti injury. Positive outcomes have been reported following IOM reconstruction with a single-bundle suture button (Mini-Tightrope) construct, although recent work suggests that double-bundle Mini-TightRope(®) IOM reconstruction is biomechanically superior. The purpose of this study was to determine whether double-bundle Mini-TightRope(®) reconstruction of the forearm IOM results in superior clinical outcomes to the single-bundle technique...

BACKGROUND: Premature infants are at high risk of early-onset sepsis (EOS) relative to term infants, and most are administered empirical antibiotics after birth. We aimed to determine if factors evident at birth could be used to identify premature infants at lower risk of EOS. METHODS: Study infants were born at 22 to 28 weeks' gestation in Neonatal Research Network centers from 2006 to 2014. EOS was defined by isolation of pathogenic species from blood or cerebrospinal fluid culture at ≤72 hours age...

A cicada wing has a biocidal feature of rupturing the membrane of cells, while the cactus spine can transmit a water drop to the stem of the plant. Both of these properties have evolved from their respective unique structures. Here, we endeavor to develop geometry-controllable nanohairs that mimic the cicada's wing-like vertical hairs and the cactus spine-like stooped hairs, and to quantitatively characterize the cell migration behavior of the hairy structures. It was found that the neuroblastoma cells are highly sensitive to the variation of surfaces: flat, vertical, and stooped nanohairs (100 nm diameter and 900 nm height)...
