External validation of and improvement upon a model for the prediction of placenta accreta spectrum severity using prospectively collected multicenter ultrasound data.

Introduction: This study aimed to validate the Sargent risk stratification algorithm for the prediction of placenta accreta spectrum (PAS) severity using data collected from multiple centers and using the multicenter data to improve the model.

Material And Methods: We conducted a multicenter analysis using data collected for the IS-PAS database. The Sargent model's effectiveness in distinguishing between abnormally adherent placenta (FIGO grade 1) and abnormally invasive placenta (FIGO grades 2 and 3) was evaluated.

Outcome of a patient with Herlyn-Werner-Wunderlich syndrome treated with Balloon septostomy - pre- and postsurgical ultrasound findings.

Herlyn-Werner-Wunderlich syndrome is an unusual congenital anomaly defined by a triad of congenital defects of the female urogenital tract - homolateral renal agenesis, uterus duplex and obstructed hemi-hematometrocolpos whose etiology remains still unclear. Pelvic pain, dysmenorrhea and palpable mass due to the hematocolpos or hematometra are the most common clinical symptoms. Endometriosis is considered to be a prevalent finding in these young patients possibly explaining the pathophysiological mechanism of endometriosis as the result of retrograde menstruation.

Rapid non-invasive prenatal screening test for trisomy 21 based on digital droplet PCR.

Non-invasive prenatal tests for the detection of fetal aneuploidies are predominantly based on the analysis of cell-free DNA (cfDNA) from the plasma of pregnant women by next-generation sequencing. The development of alternative tests for routine genetic laboratories is therefore desirable. Multiplex digital droplet PCR was used to detect 16 amplicons from chromosome 21 and 16 amplicons from chromosome 18 as the reference.

Effect of umbilical cord drainage after spontaneous delivery in the third stage of labor.

Unlabelled: Umbilical cord drainage involves releasing the cord clam from the umbilical cord after separation of the newborn from the maternal end of the umbilical cord. Consequently, there is emptying of blood from the placenta. This procedure is part of the active management of the third stage of labor (TSL).

Anxiety and depressive symptoms in pregnant women during the COVID-19 pandemic in the Czech Republic-Broader sociodemographic causes, connections and implications.

Introduction: Our study (part of multicentric "MindCOVID") investigates risk factors for anxiety and depression among pregnant women during the COVID-19 pandemic in the Czech Republic.

Material And Methods: The study used a prospective cross-sectional design. Data was collected using an online self-administered questionnaire.

Associations between nausea and vomiting in pregnancy, disgust sensitivity, and first-trimester maternal serum free β-hCG and PAPP-A.

Elevated levels of nausea and vomiting in pregnancy (NVP) and disgust sensitivity have been observed in the first trimester and both are thought to have a protective function for the mother and her fetus. Their aetiology is not clear, however, with previous studies attributing elevated NVP and disgust to various factors including endocrine changes, immunological changes, and psychological variables. To date, no study has directly assessed the relationship between disgust and NVP.

Disgust sensitivity in early pregnancy as a response to high pathogen risk.

Introduction: Considered a part of the behavioral immune system (BIS), disgust sensitivity is expected to be adjusting as a response to the actual level of the environmental health risks.

Methods: In this preregistered study, we tested the hypothesis that disgust sensitivity would be higher during the COVID-19 pandemic compared to the pre-pandemic period in pregnant women. In this between-subject study with a longitudinal trend design, we administered the Disgust Scale-Revised to 200 pregnant women before the pandemic and to 350 pregnant women during the pandemic.

Epidermolysis in a newborn of a mother affected by covid-19 in the 3rd trimester of pregnancy.

Covid-19, caused by severe respiratory syndrome coronavirus 2 (SARS-CoV-2), is currently a pandemic. Although this infection primarily presents with respiratory symptoms, the number of reported extrapulmonary manifestations, including dermatological, is also increasing. A group of pregnant women is particularly susceptible to respiratory diseases, but with regard to covid-19, there is still limited data on the course of infection in pregnancy in relation to the possibility of vertical transmission.

Risk factors for anxiety and depression among pregnant women during the COVID-19 pandemic: Results of a web-based multinational cross-sectional study.

Objective: To assess risk factors for anxiety and depression among pregnant women during the COVID-19 pandemic using Mind-COVID, a prospective cross-sectional study that compares outcomes in middle-income economies and high-income economies.

Methods: A total of 7102 pregnant women from 12 high-income economies and nine middle-income economies were included. The web-based survey used two standardized instruments, General Anxiety Disorder-7 (GAD-7) and Patient Health Questionnaire-9 (PHQ-9).

Perinatal and 2-year neurodevelopmental outcome in late preterm fetal compromise: the TRUFFLE 2 randomised trial protocol.

Introduction: Following the detection of fetal growth restriction, there is no consensus about the criteria that should trigger delivery in the late preterm period. The consequences of inappropriate early or late delivery are potentially important yet practice varies widely around the world, with abnormal findings from fetal heart rate monitoring invariably leading to delivery. Indices derived from fetal cerebral Doppler examination may guide such decisions although there are few studies in this area.

Longitudinal Doppler Assessments in Late Preterm Fetal Growth Restriction.

Purpose:  To assess the longitudinal variation of the ratio of umbilical and cerebral artery pulsatility index (UCR) in late preterm fetal growth restriction (FGR).

Materials And Methods:  A prospective European multicenter observational study included women with a singleton pregnancy, 32-36, at risk of FGR (estimated fetal weight [EFW] or abdominal circumference [AC] < 10 percentile, abnormal arterial Doppler or fall in AC from 20-week scan of > 40 percentile points). The primary outcome was a composite of abnormal condition at birth or major neonatal morbidity.

When a rare condition creates a scientific society: The history of the International Society for Placenta Accreta Spectrum (IS-PAS).

Almost 10 years ago, clinicians at multiple locations all over Europe observed an increased number of antenatally undiagnosed cases of placenta accreta spectrum (PAS) resulting in significant morbidity and the occasional maternal death. Even with an improvement in antenatal imaging, the management of severe PAS remains challenging. One solution to improve understanding in rare but potentially lethal conditions is international collaboration.

Performance of antenatal imaging to predict placenta accreta spectrum degree of severity.

Introduction: In cases of placenta accreta spectrum, a precise antenatal diagnosis of the suspected degree of invasion is essential for the planning of individual management strategies at delivery. The aim of this work was to evaluate the respective performances of ultrasonography and magnetic resonance imaging for the antenatal assessment of the severity of placenta accreta spectrum disorders included in the database. The secondary objective was to identify descriptors related to the severity of placenta accreta spectrum disorders.

Optimization of diagnostic strategy for non-invasive cell-free foetal RHD determination from maternal plasma.

Background And Objectives: The aim of the study was to optimize routine non-invasive prenatal detection of fetal RHD gene from plasma of RhD-negative pregnant women (the median of gestational age was 25 weeks, range 10-38) to detect RhD materno-fetal incompatibility and to avoid the redundant immunoprophylaxis.

Materials And Methods: Initially only one exon of RHD gene (exon 10) was investigated in 281 plasma samples (144 verified after delivery), in the second phase three RHD exons (5, 7, 10) were analyzed in 246 samples of plasma and maternal genomic DNA (204 verified) by real-time PCR method. Detection of Y-chromosomal sequence DYS-14 and five X-chromosomal insertion/deletion polymorphisms was used to confirm the fetal cfDNA detectability in plasma.

Association between latent toxoplasmosis and fertility parameters of men.

Background: About a third of people in the world are infected with Toxoplasma gondii. This parasite has been found in the reproductive organs and semen of males of many animal species as well as humans. The effects of toxoplasmosis on sperm count, motility and morphology were confirmed in rats.

Male-to-Female Presumed Transmission of Toxoplasmosis Between Sexual Partners.

Toxoplasmosis is one of the most widespread human parasitoses in developed countries. Sexual transmission has been confirmed in several animal species, and indirect evidence suggests it may occur in humans. We compared the seropositivity to Toxoplasma gondii in couples who visited the Center for Assisted Reproduction in Prague from June 2016 to June 2018 and analyzed various risk factors including the serological status of sexual partner.

Fetal cerebral Doppler changes and outcome in late preterm fetal growth restriction: prospective cohort study.

Objectives: To explore the association between fetal umbilical and middle cerebral artery (MCA) Doppler abnormalities and outcome in late preterm pregnancies at risk of fetal growth restriction.

Methods: This was a prospective cohort study of singleton pregnancies at risk of fetal growth restriction at 32 + 0 to 36 + 6 weeks of gestation, enrolled in 33 European centers between 2017 and 2018, in which umbilical and fetal MCA Doppler velocimetry was performed. Pregnancies were considered at risk of fetal growth restriction if they had estimated fetal weight and/or abdominal circumference (AC) < 10 percentile, abnormal arterial Doppler and/or a fall in AC growth velocity of more than 40 percentile points from the 20-week scan.

Evidence-based guidelines for the management of abnormally invasive placenta: recommendations from the International Society for Abnormally Invasive Placenta.

The worldwide incidence of abnormally invasive placenta is rapidly rising, following the trend of increasing cesarean delivery. It is a heterogeneous condition and has a high maternal morbidity and mortality rate, presenting specific intrapartum challenges. Its rarity makes developing individual expertise difficult for the majority of clinicians.
