Abstract

BACKGROUND The aim of the study was to investigate whether the angle of progression (AoP), as measured by transperineal ultrasound, was predictive of both the time remaining in labor and vaginal delivery. METHODS This was a prospective observational cohort study involving 270 low-risk women with singleton pregnancies at term. The AoP, measured at the end of the first stage of labor, was used as a predictive variable of time remaining in labor and mode of delivery. The Kaplan Meier and Cox algorithms were used to evaluate the time elapsed between AoP measurement and delivery as a function of AoP. Instead, logistic regression was used to calculate the adjusted probability of vaginal delivery as a function of AoP. RESULTS Of the 270 women enrolled, 15 (5.6%) delivered by cesarean section and 33 (12.1%) by vacuum or forceps. The AoP, stratified by quartiles, was a significant predictor of the time remaining in labor, even after adjustment for possible confounders (Body Mass Index [BMI], oxytocin administration and parity). The mean±SD second stage of labor length for each AoP quartile was 134±25, 126±18, 96±33 and 58±23 minutes (P value

Abstract

Aim: To better understand the pathogenic role of Helicobacter pylori (H. pylori) in pre-eclampsia (PE), and whether it is associated or not with fetal growth retardation (FGR)., Methods: Maternal blood samples were collected from 62 consecutive pregnant women with a diagnosis of PE and/or FGR, and from 49 women with uneventful pregnancies (controls). Serum samples were evaluated by immunoblot assay for presence of specific antibodies against H. pylori antigens [virulence: cytotoxin-associated antigen A (CagA); ureases; heat shock protein B; flagellin A; persistence: vacuolating cytotoxin A (VacA)]. Maternal complete blood count and liver enzymes levels were assessed at delivery by an automated analyzer., Results: A significantly higher percentage of H. pylori seropositive women were found among PE cases (85.7%) compared to controls (42.9%, P < 0.001). There were no differences between pregnancies complicated by FGR without maternal hypertension (46.2%) and controls. Importantly, persistent and virulent infections (VacA/CagA seropositive patients, intermediate leukocyte blood count and aspartate aminotransferase levels) were exclusively associated with pre-eclampsia complicated by FGR, while virulent but acute infections (CagA positive/VacA negative patients, highest leukocyte blood count and aspartate aminotransferase levels) specifically correlated with PE without FGR., Conclusion: Our data strongly indicate that persistent and virulent H. pylori infections cause or contribute to PE complicated by FGR, but not to PE without feto-placental compromise.
