Gestational weight trajectory and risk of adverse pregnancy outcomes among women with gestational diabetes mellitus: A retrospective cohort study.

The aim of this study was to explore gestational weight gain (GWG) trajectories and their associations with adverse pregnancy outcomes. A retrospective cohort study including 11,064 women with gestational diabetes mellitus (GDM) was conducted between 2015 and 2019 in China. The latent class trajectory model was used to identify GWG trajectories, and logistic regression was performed to examine odds ratio (OR) of pregnancy outcomes.

The possible impact of the universal two-child policy on pregnancy outcomes.

Purpose: The implementation of the universal two-child policy contributes to adverse pregnancy outcomes, but how the policy change leads to adverse pregnancy outcomes is not well elaborated. In this study, we aimed to compare maternal characteristics and complications, accessed the change in the proportion of maternal characteristics and maternal complications, and evaluated the mediation of maternal characteristics on maternal complications.

Methods: Demographic and clinical data of three-level sample facilities were extracted from China's National Maternity Near Miss Obstetrics Surveillance System from Jan 1, 2012 to May 31, 2021.

Interactive effect of prepregnancy overweight/obesity and GDM history on prevalence of GDM in biparous women.

Background: Prepregnancy overweight/obesity (OWO) and gestational diabetes mellitus (GDM) history may increase the prevalence of GDM in parous women, but little is known about their potential combined effect on the prevalence of GDM in biparous women.

Objective: This study aims to explore the interactive effect of prepregnancy overweight/obesity (OWO) and GDM history on the prevalence of GDM in biparous women.

Methods: A retrospective study was conducted on 16,282 second-birth women who delivered a single neonate at ≧28 weeks of gestation twice.

Two-stage nomogram models in mid-gestation for predicting the risk of spontaneous preterm birth in twin pregnancy.

Purpose: This study aimed to develop two-stage nomogram models to predict individual risk of preterm birth at < 34 weeks of gestation in twin pregnancies by incorporating clinical characteristics at mid-gestation.

Methods: We used a case-control study design of women with twin pregnancies followed up in a tertiary medical centre from January 2018 to March 2019. Maternal demographic characteristics and transvaginal cervical length data were extracted.

Establishment of an antepartum predictive scoring model to identify candidates for vaginal birth after cesarean.

Background: Evidence-based medicine has shown that successful vaginal birth after cesarean (VBAC) is associated with fewer complications than an elective repeat cesarean. Although spontaneous vaginal births and reductions in cesarean delivery (CD) rates have been advocated, the risk factors for VBAC complications remain unclear and failed trials of labor (TOL) can lead to adverse pregnancy outcomes.

Methods: To construct an antepartum predictive scoring model for VBAC.

Safety and feasibility of trial of labor in pregnant women with cesarean scar diverticulum.

Objective: Literature on trial of labor after cesarean section (TOLAC) in women with isthmoceles is scarce because of complications associated with the procedure. This study investigated TOLAC's safety and feasibility in patients with isthmoceles.

Methods: The study group comprised 34 pregnant women with isthmoceles who vaginally delivered.

Prediction of vaginal birth after cesarean delivery in Southeast China: a retrospective cohort study.

Background: We aimed to develop and validate a nomogram for effective prediction of vaginal birth after cesarean (VBAC) and guide future clinical application.

Methods: We retrospectively analyzed data from hospitalized pregnant women who underwent trial of labor after cesarean (TOLAC), at the Fujian Provincial Maternity and Children's Hospital, between October 2015 and October 2017. Briefly, we included singleton pregnant women, at a gestational age above 37 weeks who underwent a primary cesarean section, in the study.

Establishment and assessment of a nomogram for predicting adverse outcomes of preterm preeclampsia.

Objective: This prospective study was designed to develop and internally validate an accurate prognostic nomogram model with which to predict the adverse outcomes of preterm preeclampsia.

Methods: Pregnant women with preeclampsia were divided into the adverse outcome group and the no adverse outcome group. The Kaplan-Meier method, univariate Cox regression analysis, and calculation of the concordance index (C-index) were applied to predictive evaluation of the nomogram.

Clinical characteristics of mirror syndrome: a retrospective study of 16 cases.

The exact prevalence of mirror syndrome remains unclear, and the precise clinical features need to be disclosed. We retrospectively reviewed 85 cases of foetal hydrops from a total of 98,484 deliveries. Of these 16 showed mirror syndrome, while 69 did not.

Factors related to morbidity and maternal and perinatal outcomes of umbilical cord torsion.

Objective: This study analyzed factors influencing umbilical cord torsion, measured the umbilical coiling index (UCI) postnatally, and analyzed the association of umbilical cord torsion with maternal and perinatal outcomes.

Methods: In total, 845 antenatal women who went into labor at the Fujian Provincial Maternity and Children’s Hospital from January 2016 to January 2017 were retrospectively studied. The patients were divided into those with and without umbilical cord torsion.

Labor patterns in Chinese women in Fuzhou attempting vaginal birth after previous cesarean delivery: a retrospective cohort study.

Objective: To investigate the characteristics of labor in Chinese women who successfully have vaginal birth after cesarean section (VBAC).

Methods: A retrospective cohort study was conducted in a hospital with 1000 beds between January 1 2015 and December 31 2017. A total 657 parturients with VBAC were selected.

Expression of β-catenin in human trophoblast and its role in placenta accreta and placenta previa.

Objectives: To investigate the expression of β-catenin in chorionic villi, and to explore its roles in placenta accreta and placenta previa.

Methods: We compared β-catenin expression in the control group, placenta accreta group (lesion area and normal zones), and placenta previa group (placental central and placental edge zones) by immunohistochemistry, Western blotting, and RT-PCR techniques.

Results: Compared with the normal group, the placenta accreta group had a longer length of stay, greater bleeding volume, and lower newborn birth weight.

Relationship Between Myo-Inositol Supplementary and Gestational Diabetes Mellitus: A Meta-Analysis.

To determine whether myo-inositol supplement will increase the action of endogenous insulin, which is mainly measured by markers of insulin resistance such as homeostasis model assessment of insulin resistance.PubMed, Cochrane Library, Embase, and web of science were comprehensively searched using "gestational diabetes mellitus" and "myo-inositol" to identify relevant studies. Both subject headings and free texts were adopted.
