Summary: The study evaluated the uncertainties in the sFlt-1/PlGF ratio using the theory of error propagation. Results showed that uncertainties increased linearly with ratio values and were lower for Elecsys assays compared to Kryptor assays. While uncertainties cannot eliminate differences in ratio values from different immunoassays, they can impact the interpretation of sFlt-1/PlGF ratio results, especially near predefined PE diagnosis or prognosis cut-offs.

Summary: N-terminal pro-brain natriuretic peptide (NT-proBNP) and uric acid levels are increased in preeclampsia pregnancies. Using angiogenic factors for short-term prediction of preeclampsia has limitations. A machine-learning model (MLM) combining NT-proBNP, uric acid, and sFlt-1/PlGF ratio improves the prediction accuracy for preterm preeclampsia.

Summary: This retrospective real-world study investigated the clinical utility of sFlt-1/PlGF ratio in predicting adverse outcomes in patients with signs and symptoms of preeclampsia. The study found that patients classified as high or intermediate risk based on the ratio were more likely to have adverse outcomes, and combining biomarker measurements with all available clinical information improved detection of adverse outcomes in women with suspected disease.

Summary: Exosomes derived from human umbilical cord mesenchymal stem cells (HUCMSCs) have beneficial effects on adverse birth outcomes in a preeclampsia mouse model induced by sFlt-1. They can decrease blood pressure, improve fetal birth weight, and restore placental vascular networks. In addition, HUCMSC-exos partially rescue sFlt-1-induced dysfunction of human umbilical vein endothelial cells.

Summary: This study compared the predictive performance of serum placental growth factor (PlGF) and soluble fms-like tyrosine kinase-1 (sFlt-1)/PlGF ratio with the competing-risks model utilizing maternal risk factors, mean arterial pressure (MAP), and ophthalmic artery peak systolic velocity (PSV) ratio for predicting pre-eclampsia (PE) delivery. The results showed that ophthalmic artery Doppler combined with maternal risk factors and blood pressure could potentially replace the measurement of PlGF and sFlt-1/PlGF ratio in predicting imminent PE.

Summary: Research indicates that soluble fms-like tyrosine kinase 1 (sFLT-1) and placental growth factor (PLGF) have diagnostic and prognostic significance for women with preeclampsia. However, there is sparse research on these biomarkers in women with preexisting comorbidities. This study found that women with comorbidities may develop preeclampsia with a milder elevation in sFLT-1: PlGF ratio. This finding has clinical and research implications.

Summary: Obese women with pre-eclampsia have a higher risk of adverse perinatal outcome. The measurement of sFlt-1/PIGF ratio in maternal serum can be helpful for both diagnosis of pre-eclampsia and prediction of adverse perinatal outcome. However, obese women show lower levels of sFlt-1, resulting in poorer performance of sFlt-1/PIGF as a predictor for adverse perinatal outcome.

Summary: In a retrospective cohort study at S. Orsola Hospital in Bologna, Italy, 140 fetuses suspected of CoA were evaluated using fetal echocardiography. Arch hypoplasia showed the highest correlation with postnatal CoA, with affected neonates having lower Z scores of the ascending aorta and aortic isthmus. An odds ratio-based multiparametric model was developed to build a scoring system (AUC 0.89) for better identification of affected fetuses.

Summary: The timing of surgery for meningioma diagnosed during pregnancy depends on factors like PR + status and impending symptoms such as visual loss or headache. Timing of neurosurgery does not seem to affect the delivery method. A multidisciplinary approach is beneficial for rapid and appropriate diagnosis, as well as better evaluation of the benefits and risks of surgery for maternal and fetal health management.

Summary: This study aimed to examine the association between maternal age and pregnancy outcomes in primigravidae women in South Korea. The medical data of singleton primigravidae women who gave birth between 2013 and 2018 were analyzed. The results showed that advanced maternal age was associated with increased rates of high-risk pregnancy complications, such as gestational diabetes, preeclampsia, and cesarean delivery. Maternal age was also positively correlated with perinatal morbidity, including preterm birth and low birth weight. Women with advanced maternal age had higher hospitalization rates and more frequent outpatient visits.

Summary: This study provides gestational-age specific reference ranges for mean uterine artery pulsatility index (UtA-PI) based on longitudinal data assessment throughout pregnancy. The results show a progressive non-linear decrease in UtA-PI during pregnancy, and the new reference ranges may have better performance in screening for placenta-associated diseases and evaluating the potential risk for pregnancy-induced hypertension and/or small-for-gestational age.

Summary: In fetuses with isolated single umbilical artery (SUA), the diameter of the remaining umbilical artery is significantly larger than in control fetuses. A diameter of <3.1 mm in the remaining artery is associated with a higher risk of fetal growth restriction (FGR). This study highlights the importance of measuring the diameter of the remaining artery to identify fetuses at risk of FGR.

Summary: Noninvasive prenatal testing (NIPT) can detect rare autosomal trisomies (RATs) other than common aneuploidies. However, conventional karyotyping is insufficient for evaluating diploid fetuses with uniparental disomy (UPD) due to trisomy rescue. This study aims to describe the need for additional prenatal diagnostic testing for confirming UPD in fetuses diagnosed with RATs via NIPT and its clinical implications.

Summary: This study compared the postoperative adhesion and pregnancy outcomes between conventional suture (CS) and barbed suture (BS) after minimally invasive myomectomy. The results showed no significant difference in the presence of postoperative adhesion and pregnancy complications between the two suture types. Therefore, the importance of barbed suture in gynecological surgery can be questioned.

Summary: In this study, the immune status in endometriosis development was investigated. Increased Th17 cell population and IL-17A level were found in the peritoneal fluid of endometriosis patients. IL-17A was shown to enhance endometrial cell survival, inhibit NK cell mediated cytotoxicity, induce HLA-G expression, and promote migration of endometrial cells. These findings suggest that targeting IL-17A could be a potential strategy for endometriosis treatment.

Summary: The aim of this study was to determine the cause-specific hazard and cumulative incidence function for umbilical cord metabolic acidemia at birth in patients experiencing the 2nd stage of labor, stratified for FIGO-2015 pathologic intrapartum cardiotocography requiring expedited delivery and duration of 2nd stage of labor. The results showed that pathologic cardiotocography and duration of 2nd stage of labor were associated with an increased risk of umbilical cord metabolic acidemia. Nulliparity, pathologic cardiotocography, and meconium-stained amniotic fluid were significant predictors of umbilical cord metabolic acidemia.
