PURPOSE: To evaluate the effectiveness of three different first trimester screening models for trisomies 21, 18 and 13, in terms of detection rate, invasive test rate and final costs. MATERIAL AND METHODS: We analyzed the distribution of risk for trisomies 21, 18 and 13 in a population of 20.831 singleton pregnancies based on maternal age, fetal heart rate, nuchal translucency, free beta human chorionic gonadotropin and pregnancy associated plasma protein A (Combined test)...

We report a full-term neonate presenting with symptomatic congenital cytomegalovirus (CMV) infection with hepatosplenomegaly, 'blueberry muffin' rash, intracranial calcifications, thrombocytopenia and respiratory distress. Maternal history was relevant for Guillain-Barré syndrome (GBS) during the first trimester of pregnancy. CMV infection is an important cause of GBS; thus, women presenting GBS during pregnancy should be screened for CMV infection. If positive, they may benefit from specialised monitoring and treatment in the antenatal period, which may decrease the risk of major neurodevelopmental sequelae of congenital CMV in the neonate...

OBJECTIVE: Atrioventricular septal defect is associated with a high risk of a chromosomal abnormality, particularly trisomy 21. The aim of this study is to assess the rate of trisomy 21 in fetuses diagnosed with an atrioventricular septal defect and to examine the influence of prior screening on the rate of trisomy 21. METHODS: Electronic ultrasound database was searched to identify fetuses diagnoses with an atrioventricular septal defect from 2002 to 2014. Rate of trisomy 21 and other aneuploidies was calculated among fetuses with normal situs...

CONTEXT: Risk of obstetric complications increases linearly with rising maternal glycaemia. Testing HbA1c is an effective option to detect hyperglycemia but its association with adverse pregnancy outcomes remains unclear. Emerging data sustains that an early HbA1c≥5.9% could act as a pregnancy risk marker. OBJECTIVE: To determine, in a multi-ethnic cohort, whether an early ≥5.9% HbA1c could be useful to identify women without diabetes mellitus at increased pregnancy risk...

BACKGROUND: Despite some studies indicating that thyroid antibody positivity during pregnancy has been associated with adverse pregnancy outcomes, evidence regarding the effects of levothyroxine (LT4) treatment of euthyroid/subclinical hypothyroid pregnant women with autoimmune thyroid disease on pregnancy outcome is limited. We aimed to assess whether pregnant women with autoimmune thyroid disease, but without overt thyroid dysfunction are affected by higher rates of adverse pregnancy outcomes...

BACKGROUND: Malaria remains one of the most important causes of morbidity and mortality in pregnant women and their newborn babies in sub-Saharan Africa. Intermittent preventive treatment in pregnancy (IPTp) is recommended by the World Health Organization (WHO) to reduce the burden of disease and improve maternal and neonatal survival and general health. Due to the growing resistance to sulfadoxine-pyrimethamine (SP), the current WHO-recommended drug for IPTp, identification of new and effective drugs is an urgent priority...

Morbidly adherent placenta (MAP) is a growing concern currently and is still a diagnostic challenge for obstetricians. As emergency hysterectomy due to unscheduled delivery in MAP carries significant risks, we aimed to evaluate whether first and second trimester serum analytes may be used in the prediction of MAP requiring hysterectomy. A retrospective chart review of all identified cases of placenta previa totalis with and without MAP was performed. A total of 316 pregnant women diagnosed as placenta previa totalis were identified and included in the analysis...

OBJECTIVE: Serum markers measured early in pregnancy have been associated with the later diagnosis of gestational diabetes mellitus (GDM). This study aims to explore the performance of a panel of first-trimester biochemical markers for the prediction of GDM. METHODS: A case-control study was performed that included 12 women who developed GDM and 60 controls matched for maternal and gestational age at blood collection. Levels of pregnancy-associated plasma protein A (PAPP-A), soluble endoglin, pregnancy protein 13, and adiponectin (Adipo) were measured on residual sera used in first-trimester screening for Down syndrome...

OBJECTIVES: Construct a new preeclampsia predicting algorithm in twins. METHODS: Twins sampled at 10-13 and 16-20 gestational weeks and their marker values were log transformed into multiples of the gestation-specific medians (MoMs) for singletons and entered into a new logistic regression model with/without prior risk factors. RESULTS: The cohort included 9 PE (18 samples) and 96 unaffected cases (175 samples) twin pregnant women. The algorithm constructed of PlGF, PAPP-A, PP13, Doppler UTPI, and MAP with prior risk factors generated an area under the curve of 0...

OBJECTIVE: The incidence of abnormal cervical cytology in pregnancy is similar to that reported for non-pregnant women. Furthermore, 1% of pregnant women annually screened for cervical cancer will be diagnosed with cervical intraepithelial neoplasia (CIN) of various degrees. For this reason, Pap smear should be performed in the first trimester of pregnancy. The persistence of HR-HPV infection is related to the development of CIN. However, the relationship between CIN and HR-HPV infection during pregnancy and postpartum can hardly be found...

BACKGROUND: Maternal metabolism during pregnancy is a major determinant of the intra-uterine environment and fetal outcomes. Herein, we characterize the maternal urinary metabolome throughout pregnancy to identify maternal metabolic signatures of fetal growth in two subcohorts and explain potential sources of variation in metabolic profiles based on lifestyle and clinical data. METHODS: We used (1)H nuclear magnetic resonance (NMR) spectroscopy to characterize maternal urine samples collected in the INMA birth cohort at the first (n = 412 and n = 394, respectively, in Gipuzkoa and Sabadell cohorts) and third trimesters of gestation (n = 417 and 469)...

OBJECTIVE: To describe the clinically relevant findings detected by the first trimester ultrasound (FTU) and to determine the additional value of the FTU compared to cell free DNA (cfDNA) alone. METHOD: Retrospective cohort study of patients undergoing a FTU at a maternal-fetal medicine referral practice. Fetal, gynecologic, and placental findings detected by ultrasound were analyzed with available cfDNA and diagnostic testing results. A subgroup analysis of positive ultrasound findings and cfDNA results was performed to assess the additional benefit of ultrasound evaluation in FT prenatal screening...

Siqing Nie, Jinhua Yu, Ping Chen, Yuanyuan Wang, Jian Qiu Zhang
Fetal nuchal translucency (NT) thickness is one of the most important parameters in prenatal screening. Locating the mid-sagittal plane is one of the key points to measure NT. In this paper, an automatic method for the sagittal plane detection using 3-D ultrasound data is proposed. To avoid unnecessary massive searching and the corresponding huge computation load, a model is proposed to turn the sagittal plane detection problem into a symmetry plane and axis searching problem. The deep belief network (DBN) and a modified circle detection method provide prior knowledge for the searching...
