Filter by:This prospective randomized controlled study examines whether the type of glove used (sterile vs clean) for cervical examination to assess progression in labor impacts the rates of intrapartum and/or postpartum infection in patients during labor or induction of labor at term.
Objective: The aim of this study was to investigate the predictive value of maternal serum pentraxin 3 (PTX3) and heparin-binding protein (HBP) for chorioamnionitis in preterm premature rupture of membranes (PPROM). Method: This observational prospective cohort study included a total of 180 pregnant women at 24-40 gestational weeks. There were 60 cases of term premature rupture of membranes (TPROM), 60 cases of preterm premature rupture of membranes（PPROM）and 60 cases of healthy women. The concentrations of PTX3 and HBP were measured in maternal blood and amniotic fluid using an enzyme-linked immunosorbent assay (ELISA). Western immunoblotting was used to analyze the expression of PTX3 and HBP in placental tissue. The localization and immunoreaction of PTX3 and HBP in placenta were determined via immunohistochemistry (IHC).
Assessment of labor progress via digital exams is considered the standard of care in most delivery rooms. However, this method can be stressful, painful and imprecise and multiple exams increase the risk for chorioamnionitis. Trans-perineal ultrasound (TPUS) was found to be an objective noninvasive way to monitor labor progress. The study aim is to investigate whether, in nulliparous women, the use of TPUS during labor can reduce the number of vaginal exams and the incidence of chorioamnionitis.
This study will review practices in relation to chorioamnionitis (CAM) before and after to the implementation of the Neonatal Early-Onset Sepsis (EOS) Risk Calculator to determine the effect in the nursery at Banner - University Medical Center Phoenix. Newborns enrolled will be at least 35 weeks gestational age (GA) and have a maternal diagnosis of at least suspected or confirmed CAM. The data will include those newborns whose assessment and treatment were not guided by the EOS calculator which was implemented on August 28, 2019 and those with which the EOS calculator was utilized. A secondary objective is to show the economic impact with utilization of the EOS calculator. Data collected will include full laboratory workups including complete blood counts (CBC), blood cultures, antibiotic usage, length of time in the newborn nursery and total length of stay.
Prolonged rupture of membranes has been associated with increased risk of chorioamnionitis and endometritis. In this study the investigators will investigate whether an early intervention to augment labor with oxytocin is superior to expected management for spontaneous delivery (up to 24 hours).
Objective:The purpose of this study was to explore the effect and mechanism of maternal chorioamnionitis on placental microvasculature and platelet activation among preterm infants by activating Wnt-Flt1 signal pathway . Methods:With clinical randomized controlled trial (RCT), the cases were matched with 1:1 according to gestational age and divided into 2 groups according to the placental pathology result: chorioamnionitis group and control group. (1) To observe the platelet parameter, birth weight, thrombrocytopenia and hemorrhage complication, such as intracranial hemorrhage, retinal hemorrhage, pulmonary hemorrhage and gastrointestinal hemorrhage. (2) To observe the miscrovascular density (MVD) in placenta, platelet activating factor (CD62p,CD63) and thrombopotetin (TPO) in preterrn infants.The placental MVD was assessed by immunohistochemical method. The platelet activating factors were detected by flow cytometry. TPO was detected by ELISA. (3) To observe Wnt5a, Flt1 and VEGF in placenta and fetal circulation.The measurement data were analyzed by pair t test and conditional logistic regression. Pearson correlation analysis was used for relationship.
Retrospective Chart Review to determine the selective use of antibiotics in neonates born to mothers with suspected chorioamnionitis
Circulating markers to diagnose complications (sepsis, necrotizing enterocolitis) in preterm infants are often inaccurate, partly due to the lack of comprehensive studies with temporal evaluation from birth until a disease onset. The investigators plan to collect weekly blood samples of preterm infants from birth until 4 weeks of age to comprehensively characterize differential protein and epigenetic markers in infants with and without complications (sepsis, necrotizing enterocolitis, chorioamnionitis).
The purpose of this study is to determine whether antibiotics can be safely avoided in women who develop a fever during labor. Because investigators have no accurate tests to determine whether women who develop fever during labor have intra-amniotic infection, antibiotics are often used to prevent spread of infection to the fetus.
Histologic chorioamnionitis (HCA) may lead to the fetal inflammatory response syndrome (FIRS) and increased levels of proinflammatory molecules.
