OBJECTIVE To validate the possibility that human uterine electrical events (electromyographic signals) can be recorded and characterized from the abdominal surface during pregnancy. METHODS The gestational ages ranged from 20 to 43 weeks. The study included patients at term but not in labor, patients in active labor (term and preterm), postpartum(More)
Preterm labour and resultant preterm birth are the most important problems in perinatology. Countless efforts have failed to establish a single effective treatment of preterm labour, partly because the mechanisms regulating the uterus and cervix during pregnancy are not well understood. New knowledge is needed to inhibit early progression of labour (uterine(More)
BACKGROUND Intra-amniotic inflammation is associated with poor neonatal outcome independent of prematurity. We applied proteomic technology (SELDI: surface-enhanced laser desorption ionisation) to identify the proteomic profile of intra-amniotic inflammation. DESIGN One hundred and four samples of amniotic fluid were analysed. In stage 1, samples from(More)
TLRs are pattern recognition transmembrane receptors that play key roles in innate immunity. A recently discovered soluble truncated form of TLR2 (sTLR2) acts as a decoy receptor, down-regulating the host inflammatory response to bacteria. To identify the presence and functional role of sTLR2 in modulating the intraamniotic inflammatory response to(More)
Preeclampsia, a common pregnancy disorder associated with an increase in systemic inflammation, is the leading cause of maternal and fetal morbidity and mortality throughout the world. It is associated with shallow extravillous trophoblast invasion of the decidua, leading to uteroplacental blood flow that is inadequate for the developing fetal-placental(More)
OBJECTIVE We implemented a comprehensive strategy to track and reduce adverse events. STUDY DESIGN We incrementally introduced multiple patient safety interventions from September 2004 through November 2006 at a university-based obstetrics service. This initiative included outside expert review, protocol standardization, the creation of a patient safety(More)
Intra-amniotic infection and inflammation are major causes of preterm birth (PTB). However, intra-amniotic inflammation is often detected in the absence of infection. This may partly be due to the culturing methods employed in hospital laboratories, which are unable to detect the uncultivated species. In this study, intra-amniotic microbial infections(More)
Immune activation represents an adaptive reaction triggered by both noxious exogenous (microbes) and endogenous [high mobility group box-1 protein (HMGB1), S100 calcium binding proteins] inducers of inflammation. Cell stress or necrosis lead the release of HMGB1 and S100 proteins in the extracellular compartment where they act as damage-associated molecular(More)
OBJECTIVE Intrauterine and maternal systemic infections are proposed causes of preterm labor. The resulting prematurity is associated with 75% of infant mortality and 50% of long-term neurologic handicaps. We hypothesize that free radicals generated in large quantities during an inflammatory response shift the fetomaternal redox balance to an oxidative(More)
Our goal was to determine the relationship between 4 amniotic fluid (AF) proteomic biomarkers (human neutrophil defensins 2 and 1, calgranulins C and A) characteristic of intra-amniotic inflammation, and funisitis and early-onset sepsis in premature neonates. The mass restricted (MR) score was generated from AF obtained from women in preterm labor (n =(More)
