A retrospective cohort survey of problems related to second childbirths during the 2-child policy period in Jiangbei District of Ningbo City in China

Uterus-preserving surgical management of placenta accreta spectrum disorder: a large retrospective study

BACKGROUND

The two-child policy implemented in China resulted in a surge of high-risk pregnancies among advanced maternal aged women and presented a window of opportunity to identify a large number of placenta accreta spectrum (PAS) cases, which often invoke severe blood loss and hysterectomy. We thus had an opportunity to evaluate the surgical outcomes of a unique conservative PAS management strategy for uterus preservation, and the impacts of magnetic resonance imaging (MRI) in PAS surgical planning.

METHODS

Cross-sectional study, comparing the outcomes of a new uterine artery ligation combined with clover suturing technique (UAL + CST) with the existing conservative surgical approaches in a maternal public hospital with an annual birth of more than 20,000 neonates among all placenta previa cases suspecting of PAS between January 1, 2015 and December 31, 2018.

RESULTS

From a total of 89,397 live births, we identified 210 PAS cases from 400 singleton pregnancies with placenta previa. Aside from 2 self-requested natural births (low-lying placenta), all PAS cases had safe cesarean deliveries without any total hysterectomy. Compared with the existing approaches, the evaluated UAL + CST had a significant reduction in intraoperative blood loss (β=-312 ml, P < .001), RBC transfusion (β=-1.08 unit, P = .001), but required more surgery time (β = 16.43 min, P = .01). MRI-measured placenta thickness, when above 50 mm, can increase blood loss (β = 315 ml, P = .01), RBC transfusion (β = 1.28 unit, P = .01), surgery time (β = 48.84 min, P < .001) and hospital stay (β = 2.58 day, P < .001). A majority of percreta patients resumed normal menstrual cycle within 12 months with normal menstrual fluid volume, without abnormal urination or defecation.

CONCLUSIONS

A conservative surgical management approach of UAL + CST for PAS is safe and effective with a low complication rate. MRI might be useful for planning PAS surgery.

Factor Structures of General Health Questionnaire-12 Within the Number of Kins Among the Rural Residents in China

The 12-item general health questionnaire (GHQ-12) has been extensively used with Chinese population. Yet, it has not been used from a national representative survey in rural China. The aim of this study was to examine how number of kins associated with the factor structures of the CHQ-12 among the rural residents in China. Data were obtained from the 2009 rural-to-urban migrants survey (RUMiC). Exploratory factor analysis (EFA) (principal component analysis with varimax rotation) was performed to identify factor structures of GHQ-12 regarding number of siblings, age ranking, and number of children. To investigate the reliability of the questionnaire, Cronbach’s alpha was used. Internal consistency was assessed by confirmatory factor analysis (CFA). In all, 32171 rural residents in China from 2009 RUMiC participated in the study. The mean age of the respondents was 37.03 (SD = 19.21) years. The psychometric properties and factor structures of the GHQ-12 used were described. All of the fit indices in CFA models were satisfactory. The two-factor and three-factor structures gathered the satisfactory fit indexes in the part of 2009 subsamples. The rural version of the GHQ-12 was reliable measures of psychological distress among the rural residents in China with respect to number of kins. The two-and three-factor structures derived from the present sample, with good model fit in the CFA analysis, which suggested that two-and three-factor solution could be used to assess mental health of rural residents in rural China.

Dietary Patterns during Pregnancy Are Associated with the Risk of Gestational Diabetes Mellitus: Evidence from a Chinese Prospective Birth Cohort Study

Dietary patterns during pregnancy have been shown to influence the development of gestational diabetes mellitus (GDM). However, evidence from Asian populations is limited and inconsistent. We conducted a prospective cohort study in China to assess the relationship between dietary patterns and GDM. We administered three-day food diaries (TFD) and food frequency questionnaires (FFQ) at the second trimester. GDM was diagnosed with a 75 g 2-h oral glucose tolerance test at 24–28 weeks of gestation. We identified dietary patterns using principal components analysis and used multivariable logistic regression to investigate associations of dietary patterns with GDM. Of the 1014 participants, 23.5% were diagnosed with GDM. Both the TFD and FFQ identified a “traditional pattern”, consisting of high vegetable, fruit, and rice intake, which was associated with a lower GDM risk (odds ratio (OR) for quartile 4 versus quartile 1: 0.40, 95% CI: 0.23–0.71 for traditional pattern (TFD); OR: 0.44, CI: 0.27–0.70 for traditional pattern (FFQ)). The protective associations were more pronounced among women ≥35 years old. A whole grain–seafood TFD pattern was associated with higher risk of GDM (OR: 1.73, 95% CI: 1.10–2.74). These findings may provide evidence for making dietary guidelines among pregnant women in Chinese populations to prevent GDM.

Relationship between the IADPSG-criteria-defined abnormal glucose values and adverse pregnancy outcomes among women having gestational diabetes mellitus: A retrospective cohort study

To explore the influence of the 75 g oral glucose tolerance test (OGTT) on pregnancy outcomes and to determine the risk factors for adverse outcomes among women with gestational diabetes mellitus (GDM).This retrospective cohort study was conducted among women who had GDM and were treated between January 1, 2015 and December 31, 2017. The diagnostic criteria for GDM were proposed by the International Diabetes and Pregnancy Research Organization (IADPSG) in 2010. Women with GDM were stratified according to the number of abnormal OGTT values or the presence/absence of adverse pregnancy outcomes. Maternal characteristics, OGTT values, pregnancy outcomes, and the relationship between the latter 2 were analyzed.In total, 3221 pregnant women with GDM were included. The incidence of adverse outcomes was affected by maternal age (28-37 years, in particular; odds ratio [OR], 1.403; 95% confidence interval [CI], 1.037-1.899; P = .028), days of pregnancy (OR, 0.904; 95% CI, 0.894-0.914; P < .001), gestational weight gain (OR, 1.018; 95% CI, 1.000-1.036;, P = .048), and age of menarche (OR, 0.925; 95% CI, 0.863-0.992; P = .029). Both fasting plasma glucose (FPG) and 2-h OGTT were positively correlated with adverse outcomes, of which FPG was more predictive (FPG: OR, 1.143; 95% CI, 1.007-1.297; P = .038; 2-h OGTT: OR, 1.074; 95% CI, 1.018-1.133; P = .009). Meanwhile, higher abnormal OGTT values were associated with significantly increased risks of antenatal insulin treatment, cesarean delivery, premature delivery, gestational hypertension, premature rupture of membranes, preeclampsia, macrosomia, neonatal asphyxia, and full term low weight infants.OGTT values and the number of abnormal glucose are associated with various adverse pregnancy outcomes. Stratified management is recommended for pregnant women with GDM, especially those with fasting hyperglycemia and/or 3 abnormal OGTT values.
