<p><strong>Objective:</strong> With apoptosis being critical for the development and homeostasis of placental tissues, it is possible to hypothesize that accelerated trophoblastic apoptosis during pregnancy may result in a partial loss of trophoblastic activity or trophoblastic cell mass, and ultimately may alter the second-trimester screening test parameters. Thus, this study was conducted to investigate the influence of maternal toxoplasmosis on second-trimester aneuploidy screening tests.<br /><strong></strong></p><p><strong>Study Design:</strong> This retrospective study was conducted with 552 pregnant women admitted to our University Hospital. The demographic data such as maternal age and weight; and the main parameters of second-trimester aneuploidy screening test including maternal serum alpha-fetoprotein, unconjugated estriol (uE3) and human chorionic gonadotropin were analyzed with the comparison of their Toxoplasma immunoglobulin serology results.</p><p><strong>Results:</strong> The mean age of the pregnant women was 27.6 (17.0 - 43.0) years, and the mean maternal weight was estimated at 65.0 (40.0 - 120.0) kg.

Abstract Objective: This study aims to determine whether it is possible to predict preeclampsia by comparing postpartum results and test results of the pregnant women diagnosed with preeclampsia, whose first and/or second trimester screening tests were accessible, and to demonstrate the predictability of severity and week of onset.Background: 204 patients underwent renal transplantation in our center and 84 of them were female. Five of our patients (one of them had two births) gave birth to a total of 6 pregnancies.Method: 135 patients were diagnosed with preeclampsia and their first and/or second trimester screening tests were accessible, and 366 control participants gave birth to a healthy baby between 37-41 weeks after standard follow-up period for pregnancy and their screening tests were also accessible.Results: The study results show that the first trimester maternal serum PAPP-A level is significantly low in preeclamptic pregnant women, and that the second trimester maternal serum AFP and hCG levels are significantly high and uE3 levels are significantly low The results also suggest that the first and second trimester Down syndrome biochemical markers can be used in preeclampsia screening.Conclusion: Among these markers, uE3 is the parameter which affects the possibility of preeclampsia the most. However, the first and second trimester Down syndrome biochemical markers are not effective in predicting the severity and onset week of preeclampsia.

AbstractObjectivesIncreased placental stiffness is associated with various pathological conditions. Our objective was to evaluate the relation between the second-trimester placental elasticity value in low-risk pregnant women and poor obstetric outcomes.MethodsA total of 143 pregnant women were enrolled. Placental elasticity values were measured using the transabdominal point shear wave elastography method. 10 random measurements were obtained from different areas of the placenta. The mean was accepted as the mean placental elasticity value. Logistic regression analyses were performed to identify independent variables associated with obstetric outcomes.ResultsSecond-trimester placental elasticity value was significantly and positively associated with the poor obstetric outcomes (p=0.038). We could predict a poor outcome with 69.2% sensitivity and 60.7% specificity if we defined the placental elasticity cut-off as 3.19 kPa. Furthermore, in the multiple regression model, the placental elasticity value added significantly to the prediction of birth weight (p=0.043).ConclusionsOur results showed that the pregnancies with a stiffer placenta in the second trimester were associated with an increased likelihood of exhibiting poor obstetric outcomes. Also, placental elasticity was independently associated with birth weight.

AbstractTo evaluate the effect of age and parity on maternal cardiac diastolic function in second trimester among pregnant women with normal left ventricular ejection fraction. To analyze the correlation between impaired diastolic function and pre-eclampsia. It had been suggested that maternal cardiac adaptations during pregnancy differed between nulliparous and primiparous women and also varied according to age. Impaired cardiac function may precede pre-eclampsia. Therefore, we examined the effects of parity and age on cardiac diastolic function during pregnancy and whether impaired diastolic function during the second trimester correlates with pre-eclampsia. Women with singleton pregnancies at 13 + 0 to 27 + 6 weeks’ gestation and left ventricular ejection fraction (LVEF) ≥ 50% were retrospectively identified. Diastolic function parameters were assessed using transthoracic echocardiography. Pre-eclampsia was identified from medical records. The effect of age and parity on maternal cardiac diastolic function as well as the correlation between impaired diastolic function and occurrence rate of pre-eclampsia were examined. 376 pregnant women were included (median age: 30 years; median gestational age: 14 weeks; 171 primiparous women). LVEF was 66%. Impaired cardiac diastolic function was seen in 7.8% of pregnant women < 35 years compared with 28.6% of those ≥ 35 years (p = 0.000). ROC curve showed women with maternal age over 32 began to have a higher rate of impaired cardiac diastolic function (AUC = 0.704, p = 0.000, sensitivity = 54.5%, specificity = 75.3%). There was no difference in diastolic function indices between maternal women grouped by parity. Higher maternal age was an independent risk factor of declining Em (p < 0.05). Em < 13 cm/s was significantly associated with pre-eclampsia occurrence (HR 8.56; 95% CI 3.40–21.57) after being adjusted for confounders. Maternal age is an independent risk factor for diastolic function decline. There is no difference in cardiac diastolic function between nulliparous women and primiparous women. Pre-eclampsia occurrence is significantly higher in patients with impaired diastolic function at mid-gestation. The application of risk grading using diastolic function at mid-gestation may improve the survival outcomes of pregnant women.
