These findings suggest that LPC induces the overproduction of NO, which may increase the oxidative stress on endothelial cells and lead to endothelial cell injury.

This study was a multicenter retrospective cohort study of term nulliparous women who underwent labor, and was conducted to develop an automated machine learning model for prediction of emergent cesarean section (CS) before onset of labor. Nine machine learning methods of logistic regression, random forest, Support Vector Machine (SVM), gradient boosting, extreme gradient boosting (XGBoost), light gradient boosting machine (LGBM), k-nearest neighbors (KNN), Voting, and Stacking were applied and

Purpose: To compare the evaluation results of faculties to those of Standardized Patients(SP) participating in a Clinical Performance Examination(CPX) administered at Ewha Womans University College of Medicine. Methods: The CPX was taken by 77 fourth year medical students. Cases and checklist were developed by the medical school consortium in capital area. Six cases were used and 24 SPs participated and evaluated the students’ performances. The whole session was recorded on videotapes so that 6

Aims: Altered redox state has been related to the development of normal pregnancy (NP) and preeclampsia (PE). Endothelial K Ca 2.3 and K Ca 3.1 (K Ca s) play an important role in vasodilation, and K Ca s levels are affected by oxidative stress. We investigated the mechanisms of oxidative stress-mediated K Ca s expression modulation during NP and PE. Results: Human uterine microvascular endothelial cells were incubated in serum from normal nonpregnant women ( n = 13) and women with NP ( n = 24) o

Vanishing twin can be an independent risk factor for both sPTB and iPTB when compared with singleton pregnancy.

BACKGROUND: Among the non-invasive screening methods for the identification of fetal aneuploidy, NIPT (non-invasive prenatal testing) shows the highest sensitivity and specificity in high-risk pregnancies. Due to the low false positive rate of NIPT, it is assumed that the implementation of NIPT as a primary screening method may reduce the number of invasive fetal tests and result in a similar or lowered cost in the overall detection of Down syndrome. However, most previous studies are based on t

Background: Preterm birth is strongly associated with increasing mortality, incidence of disability, intensity of neonatal care required, and consequent costs. We examined the clinical utility of the potential preterm birth risk factors from admitted pregnant women with symptomatic preterm labor and developed prediction models to obtain information for prolonging pregnancies. Methods: This retrospective study included pregnant women registered with the KOrean Preterm collaboratE Network (KOPEN)

BACKGROUND: This study introduced machine learning approaches to predict newborn's body mass index (BMI) based on ultrasound measures and maternal/delivery information. METHODS: Data came from 3159 obstetric patients and their newborns enrolled in a multi-center retrospective study. Variable importance, the effect of a variable on model performance, was used for identifying major predictors of newborn's BMI among ultrasound measures and maternal/delivery information. The ultrasound measures incl

We suggest that urinary nephrin can be used as an early marker in pregnancies at risk for developing PE and SGA infants.

OBJECTIVE: This study was designed to review the screening performance of combined test at the Ewha Womans University Mokdong hospital. METHODS: All women admitted for routine antenatal care between January 1st 2008 and December 31st 2012 with a known pregnancy outcome were included in this study, totaling 1,156 women with singleton pregnancies presenting at 10 to 13 weeks of gestation. Women were offered screening using a combination of maternal serum pregnancy-associated plasma protein-A, free

Throughout the COVID-19 pandemic, pregnant women have been classified as a vulnerable population. However, the evidence on the effect of infection during pregnancy on maternal and neonatal outcomes is still uncertain, and related research comprising a large population of pregnant women in Asian countries is limited. We constructed a national cohort including mothers and children (369,887 pairs) registered in the Prevention Agency-COVID-19-National Health Insurance Service (COV-N), from January 1

Based on the current understanding of a preventive effect of bilateral salpingectomy on ovarian/fallopian/peritoneal cancers, the Korean Society of Obstetrics and Gynecology, Korean Society of Gynecologic Endocrinology, Korean Society of Gynecologic Oncology, Korean Society of Maternal Fetal Medicine, and Korean Society for Reproductive Medicine support the following recommendations: • Women scheduled for hysterectomy for benign gynecologic disease should be informed that bilateral salpingectomy
