RESUMO

BACKGROUND: Depression is a common and serious complication in new mothers. We investigated the hypothesis that neuraxial labor analgesia is associated with a decreased risk of postpartum depression. METHODS: In this multicenter prospective cohort study with propensity score matching, 599 nulliparous women with single term cephalic pregnancy who planned vaginal delivery were enrolled and self-selected neuraxial analgesia or not. The primary outcome was 6-week postpartum depression assessed with the Chinese version Edinburgh Postnatal Depression Scale; a score of ≥10 was set as the threshold of postpartum depression. Logistic regression models were established to assess the association between neuraxial labor analgesia and postpartum depression. RESULTS: Of the 577 parturients who completed the study, 417 (72.3%) received neuraxial analgesia and 160 (27.7%) did not. After propensity score matching, 433 parturients were included in the analysis; of whom, 279 (64.4%) received neuraxial analgesia and 154 (35.6%) did not. The incidence of postpartum depression was lower in parturients with neuraxial analgesia than in those without (14.9% [62/417] vs. 23.8% [38/160], P=0.012 before matching; 13.3% [37/279] vs. 23.4% [36/154], P=0.007 after matching). After adjustment for confounding factors, neuraxial analgesia was associated with decreased odds of postpartum depression (odds ratio [OR] 0.50, 95% CI 0.28-0.88, P=0.015 before matching; OR 0.40, 95% CI 0.21-0.77, P=0.006 after matching). LIMITATIONS: As an observational study, unidentified confounders might influence the results. CONCLUSIONS: In nulliparae with single term cephalic pregnancy preparing to give vaginal delivery neuraxial analgesia during labor was associated with a decreased risk of 6-week postpartum depression.

RESUMO

BACKGROUND: Chronic kidney disease (CKD) affects almost 3% of females of child-bearing age, who have a high risk of adverse maternal and fetal outcomes. Additionally, high renal burden as a result of pregnancy may lead to deterioration of renal function. An increasing number of women with CKD stages 3 to 5 have a strong desire to conceive, and both obstetricians and nephrologists are faced with enormous challenges in terms of their treatment and management. CASE SUMMARY: The case of a 35-year-old pregnant woman with a 10-year history of mild mesangial proliferative glomerulonephritis is described here. CKD progressed from stage 3 to stage 5 rapidly during pregnancy, and protective hemodialysis was started at 28 wk of gestation. Due to preeclampsia at 34 wk of gestation, cesarean section was performed and a healthy baby was delivered. Hemodialysis was discontinued at 4 wk postpartum. After 1 year of follow-up, her renal function was stable, and her baby exhibited good growth and development. CONCLUSION: Protective hemodialysis during pregnancy can prolong gestational age and improve maternal and fetal outcomes in women with advanced CKD.

RESUMO

Preeclampsia (PE) is a severe gestational complication, and dysfunctional placenta plays an essential role in PE pathogenesis. Although low-dose aspirin is currently the most promising prophylactic drug for PE prevention, the exact mechanism of aspirin remains unclear. A previous study reported that treatment with low-dose aspirin could ameliorate PE-like symptoms in lipopolysaccharide (LPS)-induced PE-like mouse model. This study aimed to uncover the potential mechanism of aspirin action in PE through quantitative phosphoproteomics comparison. We established the following four groups: a control (CTRL) group, an LPS-treated (L) group, an LPS + aspirin co-treatment (LA) group, and an aspirin-treated (A) group. A total of 4350 phosphosites and 4170 phosphopeptides from 1866 phosphoproteins were identified in the placenta on embryonic day 13.5. Among the significantly altered phosphoproteins identified, apoptosis-related pathways were significantly regulated in both the L group vs. CTRL group and the LA group vs. L group comparisons. We demonstrated that apoptosis was increased in the placenta of PE-like mice and was inhibited in the LA group by quantify the apoptosis-positive cells and the protein levels of cleaved caspase 3, 8, and 9. Moreover, the phosphorylation of HSP90ß (S254) and GSK3ß (Y216) may be a crucial factor in the aspirin-mediated regulation of apoptosis according to protein-protein interaction analysis. This study revealed that apoptosis regulation is a mechanism of aspirin action in PE, particularly in women with over-activated inflammation. The phosphorylation of HSP90ß (S254) and GSK3ß (Y216) could be the key intervention targets.

RESUMO

OBJECTIVE: To identify the association of the glucokinase gene (GCK) rs4607517 polymorphism with gestational diabetes mellitus (GDM) and determine whether sweets consumption could interact with the polymorphism on GDM in Chinese women. DESIGN: We conducted a case-control study at a hospital including 1015 participants (562 GDM cases and 453 controls). We collected the data of pre-pregnancy BMI, sweets consumption and performed genotyping of the GCK rs4607517 polymorphism. Logistic regression was performed to test the association between the rs4607517 polymorphism and GDM, and the stratified analyses by sweets consumption were conducted, using an additive genetic model. SETTING: A case-control study of women at a hospital in Beijing, China. PARTICIPANTS: One thousand and fifteen Chinese women. RESULTS: The GCK rs4607517 A allele was significantly associated with GDM (OR 1·35, 95 % CI 1·03, 1·77; P = 0·028). Furthermore, stratified analyses showed that the A allele increased the risk of GDM only in women who had a habitual consumption of sweet foods (sweets consumption ≥ once per week) (OR 1·61, 95 % CI 1·17, 2·21; P = 0·003). Significant interaction on GDM was found between the rs4607517 A allele and sweets consumption (P = 0·004). CONCLUSIONS: This study for the first time reported the interaction between the GCK rs4607517 polymorphism and sweets consumption on GDM. The results provided novel evidence for risk assessment and personalised prevention of GDM.

RESUMO

The gestational diabetes mellitus (GDM) diagnostic criteria recommended by the International Association of Diabetes and Pregnancy Study Group (IADPSG) were established based on the Hyperglycemia and Adverse Pregnancy Outcome (HAPO) study and have been the most commonly used criteria for determining GDM worldwide. Although individuals from mainland China were not included in the HAPO study, the IADPSG criteria have been used in China since 2011. However, the appropriateness of the criteria for evaluating maternal postpartum outcomes in mainland China are unknown. We conducted this study to determine whether the IADPSG criteria are appropriate for Chinese patients for evaluating long-term maternal postpartum outcomes.Eighty-four patients who were diagnosed with hyperglycemia during pregnancy and had delivery in Peking University First Hospital from February 2007 to December 2009 were enrolled in the study. For patients in Group A, GDM was diagnosed using both the National Diabetes Data Group (NDDG) and the IADPSG criteria, while patients in Group B, gestational impaired glucose tolerance (GIGT) was diagnosed using the NDDG criteria while GDM was diagnosed based on the IADPSG criteria. Anthropometric data, glucose metabolism, lipid profiles, ß cell function, and insulin resistance index were evaluated and compared to baseline after 5- to 6-year postpartum period.Patients in group A had significantly higher oral glucose tolerance test (OGTT) fasting, 2-hour and 3-hour plasma glucose levels compared to patients in group B at 24 to 28 weeks of gestation (P < .05). No significant differences were observed between the groups for anthropometric data, postpartum abnormal glucose metabolism (50.91% vs 44.83%, P = .596), type 2 diabetes mellitus (T2DM) (16.36% vs 3.45%, P = .167), lipid profiles, ß cell function (homeostasis model assessment ß-cell function index (HOMA-ß) 1.04 vs 0.99, P = .935) and insulin resistance (homeostasis model assessment insulin resistance index (HOMA-IR) 2.01 vs 1.69, P = .583).Patients diagnosed with GDM using either the NDDG or IADPSG criteria had abnormal glucose levels and lipid metabolism after delivery. Patients with mild hyperglycemia had similar postpartum ß-cell functional impairment and insulin resistance to those with moderate hyperglycemia during pregnancy. Hence, with respect to maternal long-term postpartum outcomes, the IADPSG diagnostic criteria for GDM could be appropriate for patients in mainland China.

RESUMO

BACKGROUND: This study aimed to investigate the association between maternal insulin resistance (IR) in the late second trimester and pregnancy outcomes, as well as to identify risk factors of IR among women with gestational diabetes mellitus (GDM). METHODS: A retrospective study was conducted among 2647 women diagnosed with GDM. IR was evaluated using the homeostasis model assessment method for IR (HOMA-IR) in the late second trimester (between 24 and 28 weeks), and the lipid profiles were measured at the same time. Patients were divided into groups based on quartiles of HOMA-IR. The information on pregnancy outcomes and risk factors was extracted from the medical records of all participants and entered electronically. Logistic regression models were used to analyze the associations between HOMA-IR and pregnancy outcomes, as well as the associations between risk factors and HOMA-IR. RESULTS: Greater IR was associated with cesarean delivery, preterm delivery, macrosomia, and large for gestational age newborns, but only significantly associated with preterm delivery after adjustment for potential confounders (P < .001). Prepregnancy body mass index (BMI), weight gain before diagnosis of GDM, and triglycerides were significantly related with IR in the late second trimester (P < .001). Besides, the total area under the curve of the diagnostic 75-g oral glucose tolerance test and glycosylated hemoglobin A1c increased from the lowest to the highest HOMA-IR groups. CONCLUSIONS: Increasing IR in the late second trimester predicts adverse pregnancy outcomes especially for preterm delivery in women with GDM. Additionally, prepregnancy BMI and weight gain before diagnosis of GDM are independent risk factors for the development of IR.

RESUMO

Background: In 2018, the Beijing Federation of Trade Unions organized a cervical cancer screening program for female employees for the first time. This study aimed to investigate the screening results of this program and determine the factors associated with human papillomavirus (HPV) infection. Methods: A total of 8297 female employees participating in the screening program between January 1, 2018, and December 31, 2018, were enrolled in this study. The methods for screening cervical cancer included ThinPrep cytology test (TCT) and HPV genotyping test. Single-factor analysis and multiple binary logistic regression analysis were used to identify the factors associated with HPV infection. Results: Of the 8297 women (median age: 43.00 years), TCT was found to be abnormal in 116 patients (1.40%) and 1169 (14.09%) were positive for HPV genotyping test. Notably, HPV-52 was the most prevalent subtype (3.05%), followed by HPV-16 (2.82%), HPV-58 (2.01%), HPV-51 (1.58%) and HPV-56 (1.49%). Multivariate logistic regression analysis revealed that taxi drivers (OR =1.98; 95% CI =1.31-2.99) and single women with a history of sexual activity (OR =2.32; 95% CI =1.41-3.82) were significantly associated with an increased risk of HPV infection (P<0.05), whereas medical workers (OR =0.67; 95% CI =0.51-0.88) and factory workers (OR =0.36; 95% CI =0.17-0.77) were protective factors for HPV infection (P<0.05). Conclusion: HPV-52, HPV-16 and HPV-58 are the most common types of high-risk HPV among female employees in Beijing. Being taxi drivers and single women with a history of sexual activity are significantly associated with the risk of HPV infection.

RESUMO

BACKGROUND: The relationship between thyroid nodules (TNs) and adiposity is controversial. This paper describes a cross-sectional investigation performed to determine the existence of any such relationship. To assess adiposity, body mass index (BMI) and visceral fat area (VFA) were utilized. METHODS: Between January 1, 2017 and March 3, 2019. Three thousand five hundred thirty four healthy people were examined using thyroid ultrasonography, visceral fat and anthropometric measurements, laboratory tests and questionnaire interview. Binary logistic regression analyses were used. RESULTS: Of the 3534 healthy subjects, 58.69% (2074/3534) of the subjects had TNs. A total of 55.91% (1976/3534) had BMI ≥ 25 kg/m2 and 39.67% (1402/3534) had VFA ≥ 100 cm2. After adjustment to address confounders, BMI-based overweight and obesity levels only correlated with higher risk TNs when used as a continuous variable (OR = 1.031, 95% CI: 1.008-1.055, P = 0.008), while VFA was both a continuous variable (OR = 1.003, 95% CI: 1.000-1.005, P = 0.034) and a categorical variable (OR = 1.198, 95% CI: 1.014-1.417, P = 0.034) associated with significantly elevated risk of TNs. Analyzing the subgroups, BMI ≥ 25 kg/m2 (OR = 1.500, 95% CI: 1.110-2.026, P = 0.008) was significantly correlated with TN risk in individuals with TG ≥ 1.7 mmol/L. VFA ≥ 100 cm2 correlated with the TN risk irrespective of age (< 50 years: OR = 1.374, 95% CI: 1.109-1.703, P = 0.004; ≥ 50 years: OR = 1.367, 95% CI: 1.063-1.759, P = 0.015) and in the following subgroups: women (OR = 4.575, 95% CI: 2.558-8.181, P = 0.000), FBG ≥ 6.1 mmol/L (OR = 1.522, 95% CI: 1.048-2.209, P = 0.027), and TG ≥ 1.7 mmol/L (OR = 1.414, 95% CI: 1.088-1.838, P = 0.010). CONCLUSIONS: Adiposity correlates with TNs. To assess TN risk in Chinese individuals, VFA is better than BMI.

RESUMO

BACKGROUND: Serum human chorionic gonadotrophin (hCG) is higher in twin than that in singleton pregnancies. As hCG stimulates the thyroid to produce more free thyroxine (FT4), which may lead to decreased thyroid-stimulating hormone (TSH) levels, the reference ranges of thyroid-related indicators may differ between singleton and twin pregnancies in the first trimester. This study aimed to establish reference ranges for thyroid-related indicators in early twin pregnancies and to compare them with singleton pregnancies. METHODS: Data of 820 twin-pregnant women were extracted from the established database of all pregnant women who delivered at Peking University First Hospital from October 2013 to May 2018; 160 who met National Academy of Clinical Biochemistry criteria were included to establish TSH and FT4 reference ranges. We screened 480 (3:1 paired) women with singleton pregnancies from the same database as controls. The Mann-Whitney test for TSH and FT4 levels was applied for comparisons between singleton and twin pregnancies. RESULTS: First-trimester reference ranges (4-12 gestational weeks) for twin pregnancies were: TSH 0.69 (0.01-3.35) mIU/L and FT4 16.38 (12.45-23.34) pmol/L. Median TSH was significantly lower at 7 to 12 gestational weeks than that at 4 to 6 gestational weeks (0.62 vs. 0.96 mIU/L, Z = -1.964, P = 0.049); FT4 was not significantly different between the two groups. Compared to singleton pregnancies, median TSH was significantly lower (0.69 vs. 1.27 mIU/L, Z = -6.538, P = 0.000), and FT4 was significantly higher (16.38 vs. 14.85 pmol/L, Z = -7.399, P = 0.000) in twin pregnancies in the first trimester. CONCLUSIONS: Specific reference ranges for thyroid-related indicators for twin pregnancies are needed to avoid a misdiagnosis of thyroid dysfunction. Moreover, establishment of separate reference ranges for 4 to 6 and 7 to 12 gestational weeks in twin pregnancies may be considered.

RESUMO

BACKGROUND: Gestational diabetes mellitus (GDM) is usually diagnosed between 24th and 28th gestational week using the 75-g oral glucose tolerance test (OGTT). It is difficult to predict GDM before 24th gestational week because fast plasma glucose (FPG) decreases as the gestational age increases. It is controversial that if FPG ≥5.1 mmol/L before 24th gestational week should be intervened or not. The aim of this study was to evaluate the value of FPG to screen GDM before 24th gestational week in women with different pre-pregnancy body mass index (BMI). METHODS: This was a multi-region retrospective cohort study in China. Women who had a singleton live birth between June 20, 2013 and November 30, 2014, resided in Beijing, Guangzhou and Chengdu, and received prenatal care in 21 selected hospitals, were included in this study. Pre-pregnancy BMI, FPG before the 24th gestational week, and one-step GDM screening with 75 g-OGTT at the 24th to 28th gestational weeks were extracted from medical charts and analyzed. The pregnant women were classified into four groups based on pre-pregnancy BMI: Group A (underweight, BMI < 18.5 kg/m), Group B (normal, BMI 18.5-23.9 kg/m), Group C (overweight, BMI 24.0-27.9 kg/m) and Group D (obesity, BMI ≥28.0 kg/m). The trend of FPG before 24th week of gestation was described, and the sensitivity and specificity of using FPG before the 24th gestational week to diagnose GDM among different pre-pregnancy BMI groups were reported. Differences in the means between groups were evaluated using independent sample t-test and analysis of variance. Pearson Chi-square test was used for categorical variables. RESULTS: The prevalence of GDM was 20.0% (6806/34,087) in the study population. FPG decreased gradually as the gestational age increased in all pre-pregnancy BMI groups until the 19th gestational week. FPG was higher in women with higher pre-pregnancy BMI. FPG before the 24th gestational week and pre-pregnancy BMI could be used to predict GDM. The incidence of GDM in women with FPG ≥5.10 mmol/L in the 19th to 24th gestational weeks and pre-pregnancy overweight or obesity was significantly higher than that in women with FPG ≥5.10 mmol/L and pre-pregnancy BMI <24.0 kg/m (78.5% [62/79] vs. 52.9% [64/121], χ = 13.425, P < 0.001). CONCLUSIONS: FPG decreased gradually as the gestational age increased in all pre-pregnancy BMI groups until the 19th gestational week. Pre-pregnancy overweight or obesity was associated with an increased FPG value before the 24th gestational week. FPG ≥5.10 mmol/L between 19 and 24 gestational weeks should be treated as GDM in women with pre-pregnancy overweight and obesity.

RESUMO

BACKGROUND: The cesarean section rate (CSR) has been a main concern worldwide. The present study aimed to investigate the CSR in Beijing, China, and to analyze the related factors of CS delivery. METHODS: An observational study was conducted in 15 medical centers in Beijing using a systemic cluster sampling method. In total, 15,194 pregnancies were enrolled in the study between June 20, 2013 and November 30, 2013. Independent t-tests and Pearson's Chi-square test were used to examine differences between two groups, and related factors of the CSR were examined by multivariable logistic regression. RESULTS: The CSR was 41.9% (4471/10,671) in singleton primiparae. Women who were more than 35 years old had a 7.4-fold increased risk of CS delivery compared with women <25 years old (odd ratio [OR] = 7.388, 95% confidence interval [CI] = 5.561-9.816, P < 0.001). Prepregnancy obese women had a 2-fold increased risk of CS delivery compared with prepregnancy normal weight women (OR = 2.058, 95% CI = 1.640-2.584, P < 0.001). The excessive weight gain group had a 1.4-fold increased risk of CS delivery compared with the adequate weight gain group (OR = 1.422, 95% CI = 1.289-1.568, P < 0.001). Gestational diabetes mellitus (GDM) women and DM women had an increased risk of CS delivery (1.2- and 1.7-fold, respectively) compared with normal blood glucose women. Women who were born in rural areas had a lower risk of CS delivery than did those who were born in urban areas (OR = 0.696, 95% CI = 0.625-0.775, P < 0.001). The risk of CS delivery gradually increased with a decreasing education level. Neonates weighing 3000-3499 g had the lowest CSR (36.2%). Neonates weighing <2500 g had a 2-fold increased risk of CS delivery compared with neonates weighing 3000-3499 g (OR = 2.020, 95% CI = 1.537-2.656, P < 0.001). Neonates weighing ≥4500 g had an 8.3-fold increased risk of CS delivery compared with neonates weighing 3000-3499 g (OR = 8.313, 95% CI = 4.436-15.579, P < 0.001). CONCLUSIONS: Maternal age, prepregnancy body mass index, gestational weight gain, blood glucose levels, residence, education level, and singleton fetal birth weight are all factors that might significantly affect the CSR.

RESUMO

BACKGROUND: The endometriosis fertility index (EFI) has a predictive value for pregnancy after surgery. In vitro fertilization and embryo transfer (IVF-ET) is a good treatment to infertility. This study aimed to provide external validation of EFI, assess the factors affecting the ability of EFI to predict cumulative spontaneous pregnancy rates (PRs), and propose reasonable advice for treatment by evaluating the effect of infertility management combining surgery and IVF-ET. METHODS: This retrospective study enrolled 345 endometriosis-related infertile women after laparoscopic surgery from January 2012 to January 2016. Among them, 234 patients tried to conceive naturally and were divided into six groups according to their different EFI scores. Of the 345 patients, 307 with an EFI score ≥5 were divided into non-IVF-ET group (n = 209) and IVE-ET group (n = 98) to compare the cumulative PRs. Cumulative PRs' curves were calculated using the Kaplan-Meier product limit estimate and the differences were evaluated by log-rank test. Independent predictive factors for pregnancy were assessed using the Cox regression model. RESULTS: Significant differences in spontaneous PRs among different EFI scores were identified (χ2=29.945, P< 0.05). The least function score was proved to be the most important factor for EFI (χ2 = 6.931, P< 0.05) staging system. In patients with an EFI score ≥5 after 12 months from surgery, the cumulative PRs of those who received both surgery and IVF-ET were much higher than the spontaneous PRs of those who received surgery alone (χ2=4.160, P= 0.041). CONCLUSIONS: The EFI is a reliable staging system to predict the spontaneous PR of patients. The least function score was the most influential factor to predict the spontaneous PR. Patients with an EFI score ≥5 after 12 months from surgery are recommended to receive IVF-ET to achieve a higher PR.

RESUMO

BACKGROUND: Hyperglycemia is associated with adverse pregnancy outcomes. However, the relationships between them remain ambiguous. This study aimed to analyze the effect of different oral glucose tolerance test (OGTT) results on adverse perinatal outcomes. METHODS: This retrospective cohort study included data from 15 hospitals in Beijing from June 20, 2013 to November 30, 2013. Women with gestational diabetes mellitus (GDM) were categorized according to the number and distribution of abnormal OGTT values, and the characteristics of adverse pregnancy outcomes were evaluated. Chi-square test and logistic regression analysis were used to determine the associations. RESULTS: In total, 14,741 pregnant women were included in the study population, 2927 (19.86%) of whom had GDM. As the number of hyperglycemic values in the OGTT increased, the risk of cesarean delivery, preterm births, large-for-gestational age (LGA), macrosomia, and neonatal complications significantly increased. Fasting hyperglycemia had clear associations with macrosomia (odds ratios [OR s]:1.84, 95% confidence intervals [CI s]: 1.39-2.42,P < 0.001), LGA (OR: 1.70, 95% CI: 1.29-2.25,P < 0.001), and cesarean delivery (OR: 1.33, 95% CI: 1.15-1.55,P < 0.001). The associations were stronger as fasting glucose increased. GDM diagnosed by hyperglycemia at OGTT-2 h was more likely to lead to preterm birth (OR: 1.50, 95% CI: 1.11-2.03,P < 0.01). CONCLUSIONS: Various characteristics of OGTTs are associated with different adverse outcomes. A careful reconsideration of GDM with hierarchical and individualized management according to OGTT characteristics is needed.

RESUMO

BACKGROUND: Gestational diabetes mellitus (GDM) is associated with both short- and long-term adverse health consequences for both the mother and her offspring. The aim was to study the prevalence and risk factors for GDM in Beijing. METHODS: The study population consisted of 15,194 pregnant women attending prenatal care in 15 hospitals in Beijing, who delivered between June 20, 2013, and November 30, 2013, after 28 weeks of gestation. The participants were selected by cluster sampling from the 15 hospitals identified through random systematic sampling based on the number of deliveries in 2012. A questionnaire was designed to collect information. RESULTS: A total of 2987 (19.7%) women were diagnosed with GDM and 208 (1.4%) had diabetes in pregnancy (DIP). Age (OR: 1.053, 95% CI: 1.033-1.074, P < 0.01), family history of diabetes mellitus (OR: 1.481, 95% CI: 1.254-1.748, P < 0.01), prepregnancy body mass index (BMI) (OR: 1.481, 95% CI: 1.254-1.748, P < 0.01), BMI gain before 24 weeks (OR: 1.126, 95% CI: 1.075-1.800, P < 0.01), maternal birth weight (P < 0.01), and fasting plasma glucose at the first prenatal visit (P < 0.01) were identified as risk factors for GDM. In women with birth weight <3000 g, GDM rate was significantly higher. CONCLUSIONS: One out of every five pregnant women in Beijing either had GDM or DIP and this constitutes a huge health burden for health services. Prepregnancy BMI and weight gain before 24th week are important modifiable risk factors for GDM. Ensuring birth weight above 3000 g may help reduce risk for future GDM among female offsprings.

RESUMO

BACKGROUND: The reports on massive transfusions (MTs) in obstetrics have recently been an increasing trend. We aimed to define the clinical features, risk factors, main causes, and outcomes of MTs due to severe postpartum hemorrhage (PPH) and the frequency trends over the past 10 years. METHODS: We retrospectively analyzed the data of 3552 PPH patients who were at ≥28 weeks of gestation in the Obstetric Department of Peking University First Hospital from January 2006 to February 2015. The clinical records of patients receiving MT with ≥5 units (approximately 1000 ml) of red blood cells within 24 h of giving birth were included. The Pearson's Chi-square and Fisher's exact tests were used to compare the frequency distributions among the categorical variables of the clinical features. RESULTS: One-hundred six women were identified with MT over the 10-year period. The MT percentage was stable between the first 5-year group (2006-2010) and the second 5-year group (2011-2015) (2.5‰ vs. 2.7‰, χ2 = 154.85, P = 0.25). Although uterine atony remained the main cause of MT, there was a rising trend for placental abnormalities (especially placenta accreta) in the second 5-year group compared with the first 5-year group (34% vs. 23%, χ2 = 188.26, P = 0.03). Twenty-four (23%) women underwent hysterectomy, and among all the causes of PPH, placenta accreta had the highest hysterectomy rate of 70% (17/24). No maternal death was observed. CONCLUSIONS: There was a rising trend for placental abnormalities underlying the stable incidence of MT in the PPH cases. Placenta accreta accounted for the highest risk of hysterectomy. It is reasonable to have appropriate blood transfusion backup for high-risk patients, especially those with placenta accreta.
