Gestational diabetes mellitus (GDM) is associated with an increased risk of suffering diverse adverse pregnancy outcomes, threating maternal and child health seriously, with an increasing incidence rate year by year. However, the exact cause of GDM is still unknown. Prospective cohort studies obtain data through follow-up, which is helpful to clarify the causal relationship, so as to draw more accurate and reliable conclusions. In recent years, numerous prospective cohort studies on the GDM have emerged. This article elaborates along the occurrence and development process of GDM, in order to provide useful reference for the establishment of relevant high-quality prospective cohort studies in China.

3.Research progress on mosaic embryo transfer and pregnancy risk.
Chinese Journal of Preventive Medicine 2023;57(6):949-954
Mosaic embryos contain two or more genetically distinct cell lines, which can be detected by pre-implantation genetic testing for aneuploidy. At present, it has been reported that mosaic embryo transfer can lead to healthy live births. In order to prevent severe adverse pregnancy outcomes, such as implantation failure, abortion, congenital malformation and neonatal death after implantation of mosaic embryos, it is critical to carry out genetic counseling, prenatal diagnosis and pregnancy supervision for mosaic embryo transfer. This article reviews the selection of mosaic embryos, the pregnancy outcomes of mosaic embryo transfer, and the safety of offspring, in order to provide references for the clinical practice of mosaic embryo transfer.

Gestational diabetes mellitus(GDM)is one of the common complications during pregnancy. It is associated with many adverse pregnancy outcomes, threatening maternal and child health seriously. The exact pathogenesis of GDM remains unclear. Long term exposure to persistent organic pollutants (POPs) is considered to be one of the risk factors for GDM. More and more studies are concerned about the relationship between them. Based on the literature published at home and abroad, this article summarizes the correlation and possibly related mechanism of POPs and GDM, and explores the correlation between pops and GDM, so as to provide a new idea for the prevention of gestational diabetes.

Objective: To analyze associated factors and adverse pregnancy outcomes of postpartum hemorrhage in the caesarean section of puerperae with different types of placenta previa. Methods: This retrospective research was a case-control study. Puerperae with cesarean section of placenta previa from January 2019 to December 2020 in Women's Hospital, School of Medicine, Zhejiang University were collected and divided into the<1 000 ml control group or ≥1 000 ml postpartum hemorrhage group according to the amount of blood loss during cesarean section. Differences in continuous variables were analyzed by t-test and categorical variables were analyzed by χ2 test. The risk factors of postpartum hemorrhage were analyzed by logistic multivariate regression. Results: A total of 962 puerperae were enrolled with 773 cases in the control group and 189 cases in the postpartum hemorrhage group. The incidence of gestational weeks, gravidity, parity, induced abortion, placental accreta and preoperative hemoglobin<110 g/L was significantly different between two groups in different types of placenta previa (P<0.001). Logistic multivariate regression model analysis showed that the independent risk factors of postpartum hemorrhage in the caesarean section of low-lying placenta included placental accreta (OR=12.713, 95%CI: 4.296-37.625), preoperative hemoglobin<110 g/L (OR=2.377, 95%CI: 1.062-5.321), and prenatal vaginal bleeding (OR=4.244, 95%CI: 1.865-9.656). The independent risk factors of postpartum hemorrhage in the caesarean section of placenta previa included once induced abortion (OR=2.789, 95%CI:1.189-6.544), induced abortion≥2 (OR=2.843, 95%CI:1.101-7.339), placental accreta (OR=6.079, 95%CI:3.697-9.996), HBsAg positive (OR=3.891, 95%CI:1.385-10.929), and placental attachment to the anterior uterine wall (OR=2.307, 95%CI:1.285-4.142). The rate of postpartum hemorrhage and premature delivery in puerperae with placenta previa was higher than that in puerperae with low-lying placenta (P<0.001). Conclusions: The associated factors of postpartum hemorrhage in puerperae with different types of placenta previa are different. Placenta accreta is the common risk factor of postpartum hemorrhage in puerperae with low-lying placenta and placenta previa.

OBJECTIVE:
To investigate the relationship between serum 25(OH)D and anti-Müllerian hormone (AMH) among infertile females and their predictive impacts on in vitro fertilization and embryo transfer pregnancy outcome.
METHODS:
Totally 756 infertile females treated with assisted reproductive technology were enrolled and divided into three groups according to their vitamin D levels (group A with serum 25(OH)D≤10 μg/L, group B with serum (10-20) μg/L, and group C with serum ≥20 μg/L). The serum AMH levels were detected. The differences among the groups were analyzed, as well as the correlation between vitamin D levels and serum AMH levels in various infertility types (fallopian tube/male factor, polycystic ovary syndrome (PCOS), ovulation disorders excluded PCOS, endometriosis, unexplained infertility, and others). Also, the predictive roles of vitamin D and AMH in pregnancy outcome in all the infertile females were discussed.
RESULTS:
(1) 87.7% of the enrolled females were insufficient or deficient in vitamin D. (2) The serum AMH levels in the three groups with different vitamin D levels were 1.960 (1.155, 3.655) μg/L, 2.455 (1.370, 4.403) μg/L, 2.360 (1.430, 4.780) μg/L and there was no significant difference in serum AMH levels among the three groups (P>0.05). (3) Serum 25(OH)D and AMH levels presented seasonal variations (P < 0.05). (4) There was no prominent correlation between the serum AMH level and serum 25(OH)D level in females of various infertility types after adjusting potential confounding factors [age, body mass index (BMI), antral follicle count (AFC), vitamin D blood collection season, etc.] by multiple linear regression analysis (P>0.05). (5) After adjusting for confounding factors, such as age, BMI, number of transplanted embryos and AFC, the results of binary Logistics regression model showed that in all the infertile females, the serum AMH level was an independent predictor of biochemical pregnancy outcome (P < 0.05) while the serum 25(OH)D level might not act as a prediction factor alone (P>0.05). In the meanwhile, the serum 25(OH)D level and serum AMH level were synergistic predictors of biochemical or clinical pregnancy outcome (P < 0.05).
CONCLUSION
Based on the current diagnostic criteria, most infertile females had vitamin D insufficiency or deficiency, but there was not significant correlation between serum 25(OH)D and ovarian reserve. While vitamin D could not be used as an independent predictor of pregnancy outcome in infertile females, the serum AMH level could predict biochemical pregnancy outcome independently or jointly with vitamin D.

Pregnancy in patients with Eisenmenger syndrome (ES) is associated with high maternal mortality rates of 30%‒50%, or even up to 65% in the case of a cesarean section (Yuan, 2016). Here, we report a case of term pregnancy complicated with ES and severe pulmonary artery hypertension (PAH), which was managed by a multidisciplinary team (MDT) and resulted in an uncomplicated delivery via elective cesarean section. The goal of this study is to emphasize the importance of multidisciplinary approach in the management of pregnancy with ES, which can profoundly improve maternal and infant outcomes.

Objective: To investigate the impact of molecular classification and key oncogenes on the oncologic outcomes in patients with endometrial carcinoma (EC) and atypical endometrial hyperplasia (AEH) receiving fertility-preserving treatment. Methods: Patients with EC and AEH undergoing progestin-based fertility-preserving treatment and receiving molecular classification as well as key oncogenes test at Obstetrics and Gynecology Hospital, Fudan University from January 2021 to March 2023 were reviewed. Hysteroscopic lesion resection and endometrial biopsy were performed before initiating hormone therapy and every 3 months during the treatment to evaluate the efficacy. The risk factors which had impact on the treatment outcomes in EC and AEH patients were further analyzed. Results: Of the 171 patients analyzed, the median age was 32 years, including 86 patients with EC and 85 patients with AEH. The distribution of molecular classification was as follows: 157 cases (91.8%) were classified as having no specific molecular profile (NSMP); 9 cases (5.3%), mismatch repair deficient (MMR-d); 3 cases (1.8%), POLE-mutated; 2 cases (1.2%), p53 abnormal. No difference was found in the cumulative 40-week complete response (CR) rate between the patients having NSMP or MMR-d (61.6% vs 60.0%; P=0.593), while the patients having MMR-d had increased risk than those having NSMP to have recurrence after CR (50.0% vs 14.4%; P=0.005). Multi-variant analysis showed PTEN gene multi-loci mutation (HR=0.413, 95%CI: 0.259-0.658; P<0.001) and PIK3CA gene mutation (HR=0.499, 95%CI: 0.310-0.804; P=0.004) were associated with a lower cumulative 40-week CR rate, and progestin-insensitivity (HR=3.825, 95%CI: 1.570-9.317; P=0.003) and MMR-d (HR=9.014, 95%CI: 1.734-46.873; P=0.009) were independent risk factors of recurrence in EC and AEH patients. Conclusions: No difference in cumulative 40-week CR rate is found in the patients having NSMP or MMR-d who received progestin-based fertility-preserving treatment, where the use of hysteroscopy during the treatment might be the reason, while those having MMR-d have a higher risk of recurrence after CR. Oncogene mutation of PTEN or PIK3CA gene might be associated with a lower response to progestin treatment. The molecular profiles help predict the fertility-preserving treatment outcomes in EC and AEH patients.
