Objective: The aim of this study was to investigate the maternal serum concentrations of copper (Cu) and ceruloplasmin (CP) in patients with mild preeclampsia, severe preeclampsia, hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome, and to determine their association with the severity of the disease.Methods: This study was carried out at the largest tertiary care health center in the southeast region in Turkey and Department of Obstetrics and Gynecology, Dicle University Hospital. A total of 179 pregnant women, including 58 healthy pregnant women and 71 mild preeclampsia, 26 severe preeclampsia, and 24 HELLP syndrome cases classified according to the American College of Obstetricians and Gynecologists' 2013 guidelines were included in this prospective study. Blood samples were taken from all the pregnant women to evaluate the serum Cu and CP levels. The Cu level was determined via atomic absorption/emission spectroscopy, while the serum CP level was assessed with a nephelometric assay using an automatic image analyzer. Spearman's rank correlation tests were used to determine the correlations between the serum levels of the antioxidative markers and the preeclampsia severity.Results: The mean ± SD of the Cu was 81.2 ± 11.84 µg/dl in the mild preeclampsia cases and 160.2 ± 20.89 µg/dl in the severe preeclampsia cases (p < .001). The mean ± SD of the CP was 33.0 ± 4.81 mg/dl in the mild preeclampsia cases and 65.3 ± 9.17 mg/dl in the severe preeclampsia cases (p < .001). The Cu and CP levels were significantly higher in the patients with HELLP syndrome, which is an advanced and more severe form of severe preeclampsia, than in the mild and severe preeclampsia patients (p < .001 and p < .001, respectively). Therefore, the serum Cu and CP levels were correlated with the severity of preeclampsia (r = 859, p < .001 and r = 786, p < .001, respectively). In addition, there was a positive correlation between the serum Cu and CP levels and the systolic and diastolic blood pressure values and aspartate amino transferase levels (AST), and a negative correlation between the serum Cu and CP levels and the platelet count.Conclusion: This was the first study in which the ceruloplasmin and Cu levels were investigated in HELLP syndrome patients. When considering the results obtained in the present study, there were significant relationships between the Cu, CP levels which are the markers of oxidative stress and the preeclampsia severity.

Objective: To describe a new first-trimester sonographic landmark the maxillo-occipital line which may be useful for early screening of open spina bifida.Methods: Maxillo-occipital line was prospectively evaluated in 100 low-risk pregnancies at the time of first-trimester sonographic screening examination between 11 and 13 + 6 weeks' gestation. All the pregnant women subsequently had a normal second-trimester scan and normal outcomes. Midsagittal brain images of 14 fetuses with known diagnosis of open spina bifida were evaluated retrospectively to review the maxillo-occipital line.Results: None of the 100 fetuses evaluated prospectively with the maxillo-occipital line below the junction of the midbrain and brain stem were affected by open spina bifida. The aqueduct of Silvius to occiput distance measurement was not obtained in five cases. In all, 14 cases with a diagnosis of open spina bifida, the junction between the midbrain and brain stem, were below the maxilla-occipital line.Conclusion: Maxillo-occipital line is an easy addition to the evaluation of first-trimester screening of open spina bifida. Further studies are needed to determine the false-positive and false-negative rates of this technique. [ABSTRACT FROM AUTHOR]

Objective: We examined whether first trimester aneuploidy and pre-eclampsia screening markers predict gestational diabetes mellitus (GDM) in a large multi-ethnic cohort and the influence of local population characteristics on markers.Methods: Clinical and first trimester markers (mean arterial pressure (MAP), uterine artery pulsatility index (UtA PI), pregnancy associated plasma protein A (PAPP-A), free-β human chorionic gonadotropin (free-hCGβ)) were measured in a case-control study of 980 women (248 with GDM, 732 controls) at 11 to 13 + 6 weeks' gestation. Clinical parameters, MAP-, UtA PI-, PAPP-A-, and free-hCGβ-multiples-of-the-median (MoM) were compared between GDM and controls; stratified by ethnicity, parity, and GDM diagnosis <24 versus ≥24 weeks' gestation. GDM model screening performance was evaluated using AUROC.Results: PAPP-A- and UtA PI-MoM were significantly lower in GDM versus controls (median ((IQR) PAPP-A-MoM 0.81 (0.58-1.20) versus 1.00 (0.70-1.46); UtA PI-MoM 1.01 (0.82-1.21) versus 1.05 (0.84-1.29); p < .05). Previous GDM, family history of diabetes, south/east Asian ethnicity, parity, BMI, MAP, UtA PI, and PAPP-A were significant predictors in multivariate analysis (p < .05). The AUC for a model based on clinical parameters was 0.88 (95%CI 0.85-0.92), increasing to 0.90 (95%CI 0.87-0.92) with first trimester markers combined. The combined model best predicted GDM <24 weeks' gestation (AUC 0.96 (95%CI 0.94-0.98)).Conclusions: Addition of aneuploidy and pre-eclampsia markers is cost-effective and enhances early GDM detection, accurately identifying early GDM, a high-risk cohort requiring early detection, and intervention. Ethnicity and parity modified marker association with GDM, suggesting differences in pathophysiology and vascular risk. [ABSTRACT FROM AUTHOR]

Introduction: Prenatal diagnosis of Down syndrome (DS) is based on the calculated risk of maternal age, biochemical and ultrasonographic markers and recently by cfDNA. Differences in proteomic profiles may give an opportunity to find new biomarkers.Objective: Characterize proteome of serum of mothers carrying DS fetus.Material and Methods: Blood serum samples of three groups of women were obtained, (a) 10 non-pregnant, (b) 10 pregnant with healthy fetus by ultrasound evaluation, (c) nine pregnant with DS fetus. Sample preparation was as follows: Albumin/IgG depletion, desalting, and trypsin digestion; the process was performed in nanoUPLC MS/MS. Data analysis was made with Mass Lynx 4.1 and ProteinLynx Global Server 3.0, peptide and protein recognition by MASCOT algorithm and UNIPROT-Swissprot database.Results: Each group showed different protein profiles. Some proteins were shared between groups. Only sera from pregnant women showed proteins related to immune and clot pathways. Mothers with DS fetus had 42 specific proteins.Conclusions: We found a different serum protein profile in mothers carrying DS fetuses that do not reflect expression of genes in the extra chromosome. Further studies will be necessary to establish the role of these proteins in aneuploid fetus and analyze their possible use as potential biomarkers. [ABSTRACT FROM AUTHOR]
