BACKGROUND: While there are well-accepted standards for the diagnosis of arrested active-phase labor, the definition of a "failed" induction of labor remains less certain. One approach to diagnosing a failed induction is based on the duration of the latent phase. However, a standard for the minimum duration that the latent phase of a labor induction should continue, absent acute maternal or fetal indications for cesarean delivery, remains lacking. OBJECTIVE: The objective of this study was to determine the frequency of adverse maternal and perinatal outcomes as a function of the duration of the latent phase among nulliparous women undergoing labor induction...

Escherichia coli and Staphylococcus epidermidis are predominant causes of neonatal sepsis, particularly affecting preterm infants. Susceptibility to infection has been attributed to "immature" innate monocyte defences, but no studies have assessed global transcriptional responses of neonatal monocytes to these pathogens. Here, we aimed to identify and characterise the neonatal monocyte transcriptional responses to E. coli and S. epidermidis and the role of common modifiers such as gestational age (GA) and exposure to chorioamnionitis (a common complication of preterm birth) to better understand early life innate immune responses...

BACKGROUND: Infection induced-inflammation and other risk factors for spontaneous preterm birth (PTB) and preterm premature rupture of membranes (pPROM) may cause a redox imbalance, increasing the release of free radicals and consuming antioxidant defenses. Oxidative stress, in turn, can initiate intracellular signaling cascades that increase the production of pro-inflammatory mediators. The objective of this study was to evaluate the oxidative damage to proteins and antioxidant capacity profiles in amniochorion membranes from preterm birth (PTB) and preterm premature rupture of membranes (pPROM) and to determine the role of histologic chorioamnionitis in this scenario...

Preterm birth (PTB) is featured by less than 37weeks of gestational age or fewer than 259days since the first day from the last menstrual period. Complications of PTB are the major cause of neonatal deaths, several factors are linked to PTB increased risk including immunological and genetics. Vitamin D plays an important role in immune response modulation and its action occurs through the vitamin D receptor (VDR), which recently has been described as overexpressed in human placenta during the pregnancy. Herein we assessed two single nucleotide polymorphisms (SNPs) FokI (rs2228570 A>G) and Cdx-2 (rs11568820 T>C), within VDR, using TaqMan fluorogenic probes, and differential susceptibility to SPTB...

Chorioamnionitis is an intra-amniotic infection with serious maternal and neonatal complications. Clinical studies suggest antibiotic administration before delivery reduces the risk of complications compared to after delivery. Our center implemented a standardized intrapartum gentamicin computerized provider order entry and dosage form dispensing system intended to improve treatment initiation efficiency in hospitalized obstetric patients. The primary objective of this retrospective study was to determine if these system changes were associated with decreased time from gentamicin ordering to administration in patients with chorioamnionitis...

In the United States, perinatal brain injury (PBI) is a major cause of infant mortality and childhood disability. For a large proportion of infants with PBI, central nervous system (CNS) injury begins in utero with inflammation (chorioamnionitis/CHORIO) and/or hypoxia-ischemia. While studies show CHORIO contributes to preterm CNS injury and is also a common independent risk factor for brain injury in term infants, the molecular mechanisms mediating inflammation in the placental-fetal-brain axis that result in PBI remain a gap in knowledge...

Pregnancy in women with type 1 diabetes is associated with poor maternal and neonatal outcomes. However, the risk of these outcomes has never been evaluated in an Asian national population. In this work, we report the maternal and fetal outcomes of pregnant women with type 1 diabetes in Taiwan. A total of 2,350,339 pregnancy records created between 2001 and 2012 were obtained from the National Health Insurance database and analyzed. Here, 630 pregnancy records were identified in women having type 1 diabetes...

BACKGROUND: Cerclage placed for a sonographically short cervix has been shown to reduce the risk of preterm delivery in women with a history of prior preterm birth. While short cervix is traditionally placed before viability, the threshold gestational age at which viability is achieved continues to decrease, and, as a result, a larger subset of women may be ineligible to receive this potentially beneficial procedure. OBJECTIVE: To evaluate the association between obstetric outcomes and perioperative complications after placement of an ultrasound-indicated cerclage at periviability compared to placement in the previable period...

BACKGROUND: Preterm birth is the leading cause of morbidity and mortality among neonates in the United States. Early recognition of sepsis in this population is a challenging task since overt clinical signs can be difficult to determine. C-reactive protein (CRP), one of the most frequently non-specific used laboratory test, can indirectly aid the diagnosis of neonatal sepsis. OBJECTIVES: To evaluate the relationship between histological findings in the placenta of preterm newborns born after prolonged rupture of membranes, CRP levels, and blood cultures...

BACKGROUND: The mean age of women undergoing local treatment for pre-invasive cervical disease (cervical intra-epithelial neoplasia; CIN) or early cervical cancer (stage IA1) is around their 30s and similar to the age of women having their first child. Local cervical treatment has been correlated to adverse reproductive morbidity in a subsequent pregnancy, however, published studies and meta-analyses have reached contradictory conclusions. OBJECTIVES: To assess the effect of local cervical treatment for CIN and early cervical cancer on obstetric outcomes (after 24 weeks of gestation) and to correlate these to the cone depth and comparison group used...

OBJECTIVE: Meconium aspiration syndrome (MAS) is a common cause of neonatal morbidity and mortality. Incomplete understanding of the pathogenesis of MAS has hindered the development of specific therapies. We hypothesized that activation of Toll-like receptors (TLRs) might play a role in the pathogenesis of MAS. The present study evaluated the expression of TLR 1, 4, 7, 8 and 9 in neonates with MAS. STUDY DESIGN: The study included 39 neonates with MAS and 17 healthy gestational age-matched neonates as controls...

Edwardsiella tarda (E. tarda) is a rare pathogen in humans, especially during the peripartum period. Only a few cases of fatal neonatal infection with E. tarda have been reported. Herein, we describe a case of maternal septicemia caused by E. tarda following peripartum chorioamnionitis. The mother developed septic shock, disseminated intravascular coagulation and a post-cesarean wound hematoma with abscess. Her condition improved with multidisciplinary therapy including blood transfusion, antimicrobial agents, recombinant thrombomodulin and surgical debridement...

Acute chorioamnionitis, frequently observed in preterm placentas, is a major risk factor for the development of infection and non-infection-related adverse perinatal outcomes. MicroRNAs play important roles in immune cell development and function as well as in the development of cancers and neurologic diseases. We sought to investigate the changes in microRNA-223 (miR-223) expression and the functional significance of the changes in miR-223 expression in foetal organs in the presence of acute chorioamnionitis...

A 2240 gram boy was born at 33.2 weeks gestation with nonblanching, deeply erythematous plaques and papules on the back, flanks, and scalp (Figure 1). His mother was GBS positive and on antibiotic suppression for prior cutaneous MRSA and urinary tract infections. Intrapartum intravenous Penicillin G was administered, and the amniotic sac was artificially ruptured 4 hours prior to delivery to facilitate labor. The delivery was uncomplicated without concern for chorioamnionitis, but the patient initially required CPAP for respiratory distress with 1-minute and 5-minute Apgar scores of 7 and 8, respectively...

Chorioamnionitis is a common cause of preterm birth and may cause adverse neonatal outcomes, including neurodevelopmental sequelae. Chorioamnionitis has been marked to a heterogeneous setting of conditions characterized by infection or inflammation or both, followed by a great variety in clinical practice for mothers and their newborns. Recently, a descriptive term: "intrauterine inflammation or infection or both" abbreviated as "Triple I" has been proposed by a National Institute of Child Health and Human Development expert panel to replace the term chorioamnionitis...
