Objectives: This study aimed to compare the effectiveness of oral contraceptives and a levonorgestrel intrauterine system in treating intermenstrual bleeding due to uterine niche.

Material and methods: We retrospectively analyzed 72 patients with intermenstrual bleeding due to uterine niche from January 2017 to December 2021, of whom 41 were treated with oral contraceptives and 31 with a levonorgestrel intrauterine system. Post-treatment follow-ups at 1, 3, and 6 months were conducted to compare the efficiency and adverse effects between the two groups.

Results: In the oral contraceptive group, the effectiveness rate was higher than 80% at 1- and 3-months post-treatment and higher than 90% at 6 months. In the levonorgestrel intrauterine system group, the effectiveness rates were 58.06%, 54.84%, and 61.29% at 1, 3, and 6 months of treatment, respectively.

Conclusions: Oral contraceptives were more effective than the levonorgestrel intrauterine system in treating intermenstrual bleeding caused by uterine niche.

Objectives: To evaluate the effect of histological subtype on oncological outcome and adjuvant platinum-based chemotherapy response in patients with epithelial ovarian cancer (EOC).

Material and methods: The study group was created with stage II-IV EOC patients. Progression-free survival (PFS) and disease-specific survival (DSS) estimates were determined by using the Kaplan-Meier method. The log-rank test and cox proportional hazards model were performed.

Results: A total 396 patients were included the study. Tumor type was serous in 332 (83.8%). Two hundred and thirty-one patients (58.3%) had maximal cytoreduction. Three hundred and twenty-seven (82.6%) patients received complete clinical response. Refractory disease was present in 69 (17.4%) patients. In patients with complete clinical response, 183 (56%) patients recurred. Five-year PFS was 32% in serous group and 31% in non-serous group (p = 0.755). Five-year DSS was 78% in serous group and 87% in non-serous group (p = 0.084). On multivariate analysis, recurrence rates 1.959 times (95% CI: 1.224-3.085; p = 0.004), death rates 2.624 times (95% CI: 1.328-5.185; p = 0.005) higher in patients with optimal cytoreduction than patients with maximal cytoreduction, respectively.

Conclusions: Although the rate of maximal cytoreduction was higher in patients with non-serous tumor type, the rate of refractory disease was higher after adjuvant chemotherapy. However, the recurrence rate was higher in serous tumor type. Survival rates were similar in serous and non-serous tumor types. Maximal cytoreduction was an independent predictor factor for survival. Maximal cytoreduction should be the main target in EOC.

Objectives: To identify the high-risk factors associated with postpartum hemorrhage (PPH) after an elective cesarean delivery of twins.

Material and methods: This retrospective cohort study included all women with twin gestations who chose to have an elective cesarean delivery after 28 weeks of gestation at at the Women's Hospital, School of Medicine, Zhejiang University between September 2014 and April 2019. Women with an intrauterine fetal demise of one or both twins were excluded. PPH was defined as an estimated blood loss of ≥ 1,000 mL within 24 h of birth. A total of 532 women were analyzed and classified into the PPH group (n = 70) and the no-PPH group (n = 462). Univariate and multivariate logistic regression analyses were performed to assess the independent risk factors.

Results: Among the 532 women pregnant with twins, PPH occurred in 13.2% women (n = 70). There were statistically significant differences in preeclampsia (p = 0.005), premature rupture of membrane (PROM, p < 0.001), placenta previa (p < 0.001), anemia [hemoglobin (Hb) < 100 g/L; p = 0.003], and antenatal magnesium sulfate (MgSO₄) use (p < 0.001) between the two groups. However, the following were the independent risk factors for PPH after an elective cesarean delivery for a twin pregnancy: preeclampsia [odds ratio (OR): 2.91; 95% confidence interval (CI): 1.33-6.36], PROM (OR: 8.57; 95% CI: 2.54-28.89), placenta previa (OR: 9.46; 95% CI: 3.59-24.89), antenatal MgSO₄ use (OR: 7.64; 95% CI; 3.18-18.41), and anemia (Hb < 100 g/L; OR: 2.68; 95% CI: 1.42-5.06).

Conclusions: Preeclampsia, PROM, placenta previa,and antenatal MgSO₄ use were the risk factors for PPH after an elective cesarean delivery for twin pregnancies. Risk factor identification and prevention should be a priority.

Objectives: This study aimed at assessing the adverse outcomes of pregnancy in women with endometriosis.

Material and methods: The Cochrane, Embase and PubMed databases were searched for identifying the required studies published before June 2019. Meta-analyses of relative risk (RR) were performed under the random-effects model to estimate the risk of selected adverse outcomes of pregnancy in females with endometriosis.

Results: Twenty-eight studies (53,141 women with and 2,355,923 women without endometriosis data) were selected for meta-analysis. Endometriosis bearing females had a significantly higher risk placenta previa (RR 3.92 [95% CI 2.48-6.20]), miscarriage (RR 1.31 [95% CI 1.06-1.61), gestational hypertension (RR 1.30 [95% CI 1.02-1.65]), cesarean section (RR 1.48 [95% CI 1.33-1.65]) and preeclampsia (RR 1.18 [95% CI 1.09-1.28]). The incidence of placental abruption was not statistically significant between the groups (RR 3.62 [95% CI [0.99-13.28]).

Conclusions: Women suffering from endometriosis are at higher risks of miscarriage, preterm birth, gestational hypertension, placenta previa, cesarean section, and preeclampsia.

Objectives: This study aims to investigate the expression and role of Endoglin (ENG) in endometriosis (EM).

Material and methods: In this study, quantitative real-time polymerase chain reaction, western blot and immunohistochemistry were used to examine the expression of ENG in tissues. Cellular experiments were performed to evaluate the effect of ENG on cellular biological function. Western blot was used to examine the expression of epithelial to mesenchymal transition-related proteins.

Results: The expression of ENG was significantly higher in the ectopic endometriotic tissues than that in eutopic endometriotic tissues. Knockdown of ENG inhibited cell viability, migration and invasion, and induced cell apoptosis in hEM15A cells. Additionally, silenced ENG caused increased levels of E-cadherin and decreased levels of N-cadherin, vimentin, MMP-2 and MMP-9.

Conclusions: These results confirmed that ENG may be involved in the development of endometriosis by promoting EMT process, revealing a new insight into the pathogenesis of endometriosis and contributing to the exploration of molecular therapeutic strategies against endometriosis.

Objectives: to investigate the possibility of using the ratio of serum progesterone level to the number of follicles, according to ovarian response in the day of human chorionic gonadotrophin trigger, as a predictor of cycle outcome.

Material and methods: A prospective intervensional study was conducted at Kamal Al-Samarai Hospital for Infertility Treatment and IVF during the period from December 2020 to September 2021. Ninety infertile women underwent intracytoplasmic sperm injection (ICSI) cycles using antagonist protocol. Moreover, once the patient reached triggering criteria, meticulous recording of follicular index together with serum estrogen level and serum progesterone level are measured. Fresh embryo transfer of cleavage stage embryo is done once serum progesterone level was less than 1.5 ng/mL. A follow-up to confirm pregnancy rate and cycle outcome was done.

Results: The study showed a positive pregnancy rate of 28.9%. The relationship between progesterone follicular index (Prog/FI) ratio and (ICSI) outcome was highly significant with a p value of 0.001. Additionally, an inverse relationship, as the ratio was lower the pregnancy rate was improved, was documented. The receiver operating characteristic (ROC) curve for progesterone follicular index ratio was 0.711 with a cut off value of 0.0354 ng/mL in addition to a sensitivity of 65.6 and a specificity of 65.4.

Conclusions: The serum progesterone level is an independent factor for the prediction of intracytoplasmic sperm injection (ICSI) outcome, whereas the progesterone follicular index ratio can be used as a potential marker for predicting ICSI outcome in fresh embryo transfer.

Objectives: MicroRNAs have been observed to play a major role in various physiological processes, for instance, programmed cell death, cell division, pregnancy development, and proliferation. With the help of profiling of microRNAs in the serum of pregnant women, it is possible to link alterations in their concentration to the emergence of gestational problems. The aim of the study was to evaluate the diagnostic potential of MicroRNAs Mi 517 and Mi 526 as biomarkers in the detection of hypertension and preeclampsia.

Material and methods: The study considered 53 patients who are in their first trimester of a singleton pregnancy. Participants have been divided into two study groups, one group with normal pregnancy and another group having the risk of developing preeclampsia or who developed hypertension or preeclampsia during follow-up constitute the study group. In order to collect data associated with circulating miRNAs in serum, blood samples have been collected from the participants of the study.

Results: Based on the univariate regression model, increased expression of Mi 517 and 526 and parity status (primapara/multipara) has been obtained. The multivariate logistic analysis shows that independent risk factors for hypertension or preeclampsia are the presence of an R527 and being a primipara.

Conclusions: The study's findings have revealed that R517s and R526s act as major indicative biomarkers in the first trimester for the detection of hypertension and preeclampsia. The circulating C19MC MicroRNA was examined as a potential early indicator of preeclampsia and hypertension in pregnant individuals.

Objectives: Preeclampsia is one of the most feared complications of pregnancy, which can progress rapidly to serious complications such as death of both mother and fetus. To present, the leading cause of preeclampsia is still debated. The purpose of this article was to explore the clinical significance of S100B protein, a kind of Ca2+ -sensor protein, in the early-onset severe preeclampsia.

Material and methods: Nine pregnant women with early-onset severe preeclampsia (the study group) and 13 healthy pregnant women (the control group) were included in this study. The level of S100B in the amniotic fluid, maternal blood, and umbilical cord blood were detected by enzyme-linked immunosorbent assay (ELISA) and surface plasmon resonance imaging (SPRi) methods. Diagnostic values of S100B for early-onset severe preeclampsia were assessed by Receiver Operating Characteristic (ROC) curve analysis.

Results: The levels of S100B in maternal blood and amniotic fluid in the study group were higher than those in the control group (p < 0.05). ROC curve analysis showed that S100B detected by SPRi method (SPRi-S100B) showed a cut-off level of 181 ng/mL with sensitivity of 100%, a specificity of 84.6%, and a Youden index of 0.846 in the maternal blood, which had better clinical significance and diagnostic value (at than that detected by ELISA (ELISA-S100B).

Conclusions: The levels of S100B detected by SPRi in maternal blood can indicate early-onset severe preeclampsia and perinatal brain injury.
