Aim: Whether the use of dinoprostone pessary increased the vaginal delivery rate of labor induction in Chinese nulliparous women with term premature rupture of membranes (PROM) and unfavorable cervices? Methods: PROM women at term with singleton pregnancies and Bishop scores ≤4 who needed labor induction were enrolled in this retrospective study. They received either the dinoprostone pessary followed by oxytocin infusion if necessary (n = 102, PGE2 group) or oxytocin infusion alone (n = 103, oxytocin group). Results: Compared with oxytocin infusion alone, vaginal delivery within 12 h and total vaginal delivery were higher in the PGE2 group (28.4% vs 7.8%, p = 0.0001; 79.4% vs 62.1%, p = 0.009, respectively). There were no statistical differences between the two groups in terms of maternal and neonatal outcomes, such as postpartum hemorrhage, endometritis, third‐ and fourth‐degree vaginal lacerations and neonatal weight, 1‐ and 5‐min Apgar score ≤7, neonatal jaundice, and neonatal unit admission (p > 0.05). However, there was a higher rate of uterine hyperstimulation in the PGE2 group (20.6% vs 3.9%, p < 0.0001). The effective rate of cervical ripening increased in the PGE2 group at 8 and 12 h of labor induction (p < 0.001). Conclusions: Despite higher rates of uterine hyperstimulation, the use of dinoprostone was associated with higher rates of vaginal deliveries in Chinese nulliparous women with term PROM and Bishop scores ≤4, compared with use of oxytocin only.

Hypertensive disorder in pregnancy is a disease that occurs during pregnancy. We aimed to analyze the morbidity and maternal and infant outcomes with respect to the hypertensive disorder in pregnancy in China in 2018. Clinical data of 38 590 cases from 161 hospitals were retrospectively collected. The differences in morbidity and maternal and infant mortality among the major regions and provinces were compared. The overall national average morbidity was 4.74%, and the ratios of gestational hypertension, preeclampsia, eclampsia, chronic hypertension, and chronic hypertension with superimposed preeclampsia were 29.17%, 55.02%, 0.66%, 6.53%, and 8.62%, respectively. The overall maternal mortality was 0.61/100 000, and the case fatality was 0.13%. Morbidity associated with hypertensive disorder in pregnancy was 7.74% in North China, 6.62% in Northwest China, 6.40% in Central China, 5.83% in Northeast China, 4.28% in East China, 3.85% in South China, and 2.88% in Southwest China. The morbidity in each province was 1.62-11.28%. The overall perinatal mortality was 3.59% (81.09% for stillbirths; 18.91% for neonatal deaths). Perinatal mortality decreased with increasing gestational weeks from 24 to 37 + 6 weeks. Perinatal mortality for delivery at 32 weeks of gestation in all regions of the country was <10%. Morbidity varied across regions in China, with the lowest in Southwest and the highest in North China. The low maternal mortality is related to the large-scale development of standardized maternal health care in China. For severe hypertensive disorder patients, gestation should be prolonged to 32 weeks as often as possible for better neonatal survival rates. [ABSTRACT FROM AUTHOR]

Introduction: Adverse pregnancy outcomes are related to two opposite maternal factors, youth and aging. However, the change in trend of specific outcomes with childbearing age is unknown. The aim of this study was to investigate the changing trend of various maternal and neonatal outcomes with maternal age from 17 to 44 years.Material and Methods: Data were extracted from the medical records from 2011-2012 of 39 public hospitals of 14 cities in China. The eligibility criteria were primiparity and singleton birth. Join point regression analysis was used to estimate the percent change per year of age (PCA) to explore the trends of adverse pregnancy outcomes with regard to maternal age and to identify the join point of maternal age when the trend was changed.Results: A total of 89 171 women were eligible for analysis. There were four categories of trend styles. Continuously increasing trends were linear for placenta previa (PCA, 0.1%), placenta implantation (PCA, 0.09%) and postpartum hemorrhage (PCA, 0.22%), and nonlinear for gestational diabetes mellitus with one join point of 23 years (PCA, 0.17% and 0.71%) and cesarean section with four join points of 25, 28, 31 and 36 years (PCA, 1.39%, 0.34%, 1.51%, 3.49% and 0.94%). Continuously decreasing trends were linear for intrahepatic cholestasis (PCA, -0.02%) and nonlinear for anemia with one join point of 28 years (PCA, -0.49% and -0.04%). The bidirective trends were downward to upward for preterm birth (PCA, -2.93%, -0.36% and 0.38%), hypertension in pregnancy (PCA, -0.09%, 0.47%), low birthweight (PCA 0.51% and 0.38%), low 1-minute Apgar score (PCA, -0.28% and 0.07%), low 5-minute Apgar score at (PCA, -0.10% and 0.06%) and neonatal intensive care unit admission (PCA, -1.92%, -0.07% and 0.12%) with a nadir age of 28 years. The bidirective trend was upward to downward for macrosomia (PCA, 0.39% and -0.11%), with a peak age of 30 years.Conclusions: The changes in the trend of specific outcomes were different with maternal age, which means that youth, aging or both could affect the outcomes.

ABSTRACT Purpose To evaluate the natural history and outcome of pregnancies in patients with placental chorioangioma. Methods A total of 16 placentas with a histologic diagnosis of chorioangioma were identified, and the natural history and outcome of pregnancy were evaluated. This study was approved by the Institutional Ethics Committees of our unit, and written informed consent was obtained from all study participants. Results Thirteen of the 16 cases were associated with a wide variety of fetal complications. Two-thirds of the cases developed complications that either required elective delivery because of fetal distress (n = 4), fetal heart failure (n = 1), oligohydramnion (n = 1), and premature labor of dichorionic twins (n = 1) or resulted in intrauterine fetal death and termination of pregnancy (n = 2). Conclusions Placental chorioangioma was associated with the development of polyhydramnios, fetal growth restriction, and fetal distress in a significant number of cases. The size, vascularity, and location of the chorioangioma may be three independent factors of maternal and fetal complications. Any of these three factors can influence the outcome of pregnancy. Close antenatal examination should be routinely practiced to allow the timely diagnosis of early fetal heart failure. © 2013 Wiley Periodicals, Inc.
