Methods: We conducted a systematic review with PubMed and Web of Science from 1 January 2020 to 1 April 2023. Articles focusing on social factors and PPD during COVID-19 pandemic were investigated. Newcastle-Ottawa Scale and the Agency for Healthcare Research and Quality Scale were used to evaluate quality of literatures. Results: We included 31 articles (22 cross-sectional studies and 9 cohort studies) with good quality. Edinburgh Postnatal Depression Scale (EPDS) was used as the preferred measure for defining PPD. Social support reduced the prevalence of developing PPD by 30%–40%. Social restriction increased the risk of PPD but there was lack of evidence or effective scales to define restriction. Conclusions: We found that social support acted as an important protective factor for PPD during the COVID-19 pandemic and that social restriction increased the risk of PPD. EPDS may be an optimal choice for researchers to define PPD. Obstetricians should underline social factors for both pregnancy women and their families.

Methods: Three hundred and eighteen patients positive for high-risk HPV in the gynecological clinic of our hospital from May 2020 to June 2021 were analyzed retrospectively. Colposcopy was performed when it was clinically indicated. Results: Among the 318 patients, 203 were TS negative and 115 were TS positive, of whom 84 were referred for colposcopy and possible biopsy. Among the 318 patents, 74.53% (237/318) had a single type of HPV infection, and 25.47% (81/318) had more than two types of HPV infection. In terms of HPV types, the top 5 types were 52, 58, 51, 56 and 16. HPV52 accounted for 27.4% (87/318), followed by HPV58, accounting for 17.30% (55/318). A total of 84 patients underwent colposcopy. The negative predictive values of TS and thinprep cytology test (TCT) screening for cervical cancer and precancerous lesions were 33.33% and 16.90%, respectively. The positive predictive values were 88.41% and 92.31%, respectively. The sensitivity was 85.92% and 16.90%, respectively. The specificity was 38.46% and 92.31%, respectively. Among 251 non-16/18 high-risk HPV-positive patients with TCT negative intraepithelial lesion or malignancy (NILM) 49 underwent colposcopy. The positive predictive value of TS for cervical cancer and precancerous lesions was 84.78% and the sensitivity was 92.86%. Conclusions: This study demonstrated that in a clinical setting, TS had a better sensitivity than TCT in cervical cancer screening, but less specificity than TCT. In the non-16/18 HPV-positive population with TCT NILM, TS screening can be considered as having potential for clinical management. However, the current research sample size was small, and further research needs to be performed with a larger sample size.","PeriodicalId":10312,"journal":{"name":"Clinical and experimental obstetrics & gynecology","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135146213","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: To review the clinical data of 170 SLN-positive early breast cancer patients. We examined VEGF-C and D positive expression in cancerous and paraneoplastic tissues and counted ultrasound and pathological features. Results: The rate of VEGF-C and D positivity in cancer tissues was higher than that in paracancerous tissues (p < 0.05). The rates of VEGF-C and D positivity in the cancer tissues with vascular infiltration, number of SLN positives >2, proportion of SLN positives >0.5, burr sign on ultrasound, and NSLN metastasis were higher than those of patients without vascular infiltration, number of SLN positives ≤2, proportion of SLN positives ≤0.5, no burr sign, and no NSLN metastasis, respectively (p < 0.05). The results also showed that the presence of vascular infiltration and burr sign, a high number of SLN positivity, the percentage of SLN positivity >0.5, VEGF-C and D positivity were all NSLN metastasis independent risk factors for metastasis (p < 0.05). Receiver operating characteristic (ROC) curve analysis showed that the area under the ROC curve (AUC) for VEGF-C and D combined with ultrasound and pathological features to predict NSLN metastasis was the highest. Conclusions: The ultrasound and pathological features of SLN-positive early breast cancer patients, such as vascular infiltration, VEGF-C and D positivity, were all independent risk factors for NSLN metastasis, and VEGF-C and D combined with ultrasound and pathological features had high predictive efficacy for NSLN metastasis. It provides reliable indicators to screen for NSLN metastasis in a high-risk group from SLN-positive patients with early-stage breast cancer.","PeriodicalId":10312,"journal":{"name":"Clinical and experimental obstetrics & gynecology","volume":"2010 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135538591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to assess agreement among five colposcopists regarding the presence of three isolated colposcopic images, and different degrees of colposcopic findings. Methods: In this retrospective study, two original colposcopists examined colposcopic images of patients treated between 2005 and 2018, classified them following the International Federation for Cervical Pathology and Colposcopy terminology, and evaluated them for the presence of obstructed dilated grouped glands, aceto-white villi with invaginated borders fused or not, and atypical vessels in cylindrical epithelium area. Posteriorly, three independent colposcopists also classified those colposcopic findings. The degree of agreement between the findings of the three independent, and the two original colposcopists was assessed using the Kappa (κ) coefficient. Results: Among the 822 included patients, 67.4% had a diagnosis of cervical intraepithelial neoplasia (CIN) grades 2 or 3, 6.8% of adenocarcinoma in situ, and 11.8% of CIN 1. The agreement for each image ranged from κ 0.14 to 0.37 (p < 0.001). The highest agreements occurred for aceto-white villi with invaginated borders (κ 0.15–0.37), major (κ 0.29–0.46), and minor (κ 0.14–0.36) colposcopic findings (p ≤ 0.001).

Mechanism: Ovarian cancer is one of the leading causes of death in gynecological cancer patients, mainly affecting middle-aged and elderly women. It has the characteristics of hidden location, strong heterogeneity and lack of specific symptoms in the early stage. Numerous studies have shown that estrogen receptor (ER) plays an important role in different types of cancer, including ovarian cancer. Accordingly, the study of ER signaling pathways and related regulatory factors in ovarian cancer cells should help us understand the pathogenesis of ovarian cancer. Findings in Brief: The expression of estrogen receptor subtypes is related to ovarian cancer gene and leads to ovarian cancer. Estrogen receptor modulators appear to be an important factor in the prognosis of patients with ovarian cancer after hormone therapy. Conclusions: This review summarizes the regulatory mechanism of ER in the occurrence and development of ovarian cancer and outlines the specific role of estrogen receptor modulators (SERMs) in the treatment and prevention of ovarian cancer.","PeriodicalId":10312,"journal":{"name":"Clinical and experimental obstetrics & gynecology","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135925669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: This is a prospective analysis of 10 consecutive patients receiving surgical treatment for proven diagnosis of lumbosacral plexus nerve entrapment. Patients with symptoms of chronic pelvic pain, dyspareunia, dysmenorrhea, and severe, burning sharp pain on the lower extremity dermatomes were included. Laparoscopic decompression of lumbosacral plexus nerve entrapment with intraoperative neuromonitoring was performed between January 2021 and February 2022. Intraoperative neuromonitoring records (spontaneous electromyography (EMG), free-run EMG recordings, transcranial electrical motor-evoked potentials (TcMEP) recordings, direct nerve root stimulation recordings, and compound muscle action potentials (CMAPs) recordings) and preoperative and postoperative pain symptoms at one month were analyzed. Results: The median age of the patients was 29 (25–44) years. Neurovascular conflict, fibrosis, and abnormal piriformis muscle were identified as the three main etiologies of nerve entrapments. There were no statistically significant differences in transcranial motor evoked potential responses on the operated extremity side before and after decompression surgery or in the amplitude difference changes of TcMEP responses between the operated and non-operated extremity sides (p &gt; 0.05). Dyspareunia visual analogue scale (VAS) scores showed a significant decrease at the first month postoperatively (p-value = 0.027). Conclusions: Integrating intraoperative neurophysiological monitoring into laparoscopy facilitates the monitoring of the patient’s motor function and prevents both permanent and transient nerve damage during pelvic nerve decompression surgery. This technique holds promise in enhancing surgical safety and preserving pelvic nerve function.

However, it is unclear whether this relationship is causal. Consequently, we implemented a bidirectional Mendelian randomization (MR) analysis to examine the empirical causal association of PCOS and PTSD. Methods: We acquired genetic association data for PCOS through a comprehensive meta-analysis from several large-scale genome-wide association studies (GWASs), which enrolled 10,074 cases and 103,164 controls. For PTSD, we obtained data from a GWAS performed by the Psychiatric Genomics Consortium Posttraumatic Stress Disorder (PGC-PTSD) group. The study included a total of 23,212 cases of PTSD and 151,447 controls of European ancestry. For both PCOS and PTSD, we carefully selected genetic instruments that met the rigorous significance threshold (p < 5 × 10-8, r2 < 0.01). To investigate the causal association between PCOS and PTSD, we conducted bidirectional Mendelian randomization (MR) analyses. The primary analysis employed the inverse-variance weighted (IVW) method, complemented by alternative MR approaches such as the maximum-likelihood method, MR-Egger regression, Mendelian randomization-Robust Adjusted Profile Score (MR-RAPS), and MR Pleiotropy RESidual Sum and Outlier (MR-PRESSO) test. Sensitivity analyses were also carried out to verify the robustness of this association. Results: In this study, we identified and utilized 14 genetic variants as instruments for PCOS, while 2 genetic variants were selected as instruments for PTSD. Our findings demonstrated that a genetic predisposition to PCOS was significantly associated with an elevated risk of developing PTSD (odds ratio (OR) = 1.11, 95% confidence interval (CI): 1.03–1.19, p = 7.27 × 10-3 for IVW). MR-Egger regression analysis was performed, and the results did not provide evidence of directional pleiotropy (p intercept = 0.187). Sensitivity analyses utilizing alternative MR methods consistently yielded similar results, supporting the robustness of our findings. Furthermore, in the reverse MR analysis, we observed no significant association between genetic predisposition to PTSD and the risk of developing PCOS (OR = 1.15, 95% CI: 0.69–1.91, p = 0.586 for IVW). Comparable null associations were also observed when alternative MR methods were employed. Conclusions: Through a genetic epidemiological approach, we found that genetic predisposition to PCOS was associated with an increased risk of PTSD, suggesting a potential causal relationship between PCOS and PTSD. Nonetheless, further investigation is necessary to elucidate the underlying mechanism through which PCOS contributes to the development of PTSD.","PeriodicalId":10312,"journal":{"name":"Clinical and experimental obstetrics & gynecology","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136313513","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: We recruited 110 pregnant women with GDM and 100 pregnant women without GDM who had normal 75 g oral glucose tolerance test (OGTT) results between June 2019 and June 2021. We collected basic data from all participants and compared serum FT3 and FT4 levels, SCH, and TPOab (+) incidences in the first trimester between the two groups. We used logistic regression to identify factors that influence the development of GDM. Results: Serum FT3 levels were 4.58 ± 0.78 and 4.61 ±1.42 pmol/L in the GDM group and Control group, while FT4 levels were 9.32 ± 2.54 and 10.24 ± 2.77 pmol/L. The incidence of SCH were 25.5% and 14.0%, while TPO (+) were 20.0% and 10.0%. The GDM group’s FT4 levels were significantly lower than the control group’s, whereas the GDM group’s age, incidence of SCH, and TPOab (+) were significantly higher (p < 0.05). Logistic regression analysis demonstrated that age, SCH and TPO (+) were risk factors for GDM (p < 0.05), the regression equation: logit p = –3.484 + 0.105 (age) + 1.128 (SCH) + 1.294 (TPOab (+)).
