The objective was to assess the sensitivities and accuracies of Doppler ultrasound parameters in the second and third trimester of hypertensive pregnancies in determining perinatal outcomes. 1,054 pregnancies were retrospectively categorized into three groups (healthy pregnancies (HP, n = 988), pregnancies of hypertensive women (HypP, n = 30) and high-risk hypertension pregnancies (HRHypP, n = 36), depending on gestational hypertension as well as fetal birth weights and pregnancy outcomes. Systolic/diastolic ratio (S/D), resistance index (RI), pulsatility index (PI) of the bilateral uterine artery, umbilical artery and vein as well as venous flow velocity data were monitored by Doppler ultrasound...

BACKGROUND: Reduced fetal middle cerebral artery Doppler impedance is associated with hypoxemia in fetal growth restriction. It remains unclear as to whether this finding could be useful in timing delivery especially in third trimester. In this regard there is a paucity of evidence from prospective studies. OBJECTIVES: The aim of this study was to determine whether there is an association between middle cerebral artery Doppler impedance and its ratio with the umbilical artery in relation to neonatal and 2-year infant outcome in early fetal growth restriction (26(+0)-31(+6) weeks of gestation)...

OBJECTIVE: To assess the association of subsequent pregnancy with subsequent metabolic syndrome and type II diabetes mellitus after a pregnancy complicated by mild gestational diabetes mellitus (GDM). METHODS: We conducted a prospective observational follow-up study of women with mild GDM randomized from 2002 to 2007 to usual care or dietary intervention and glucose self-monitoring. Women were evaluated 5-10 years after the parent study. Participants were grouped according to the number of subsequent pregnancies (group A, none [reference]; group B, one; group C, two or greater)...

Polyploidy, the state of having greater than a diploid DNA content (tetraploid, octoploid, etc.) is a characteristic feature of mammalian hepatocytes and accompanies late fetal development and postnatal maturation of the liver. During the weaning period, diploid hepatocytes can engage either into normal cell division cycle giving rise to two diploid hepatocytes or follow a scheduled division program characterized by incomplete cytokinesis. In that case, diploid hepatocytes undergo mitosis, but do not form a contractile ring...

Preeclampsia with severe features (SPE) remote from term remains a major cause of maternal morbidity and mortality worldwide. With increasing diagnosis of SPE remote from term and improved methods for monitoring maternal and fetal well-being, several challenges have been made regarding management of preeclampsia. We reviewed the scientific literature of the diagnosis and outcome of SPE before 28 weeks. On the basis of this review, we will present our recommendations on management of SPE before 28 weeks' gestation...

OBJECTIVE Fetal ventriculomegaly (FV), or enlarged cerebral ventricles in utero, is defined in fetal studies as an atrial diameter (AD) greater than 10 mm. In postnatal studies, the frontooccipital horn ratio (FOHR) is commonly used as a proxy for ventricle size (VS); however, its role in FV has not been assessed. Using image analysis techniques to quantify VS on fetal MR images, authors of the present study examined correlations between linear measures (AD and FOHR) and VS in patients with FV. METHODS The authors performed a cross-sectional study using fetal MR images to measure AD in the axial plane at the level of the atria of the lateral ventricles and to calculate FOHR as the average of the frontal and occipital horn diameters divided by the biparietal distance...

The processing of ECG signal provides a wealth of information on cardiac function and overall cardiovascular health. While multi-lead ECG recordings are often necessary for a proper assessment of cardiac rhythms, they are not always available or practical, for example in fetal ECG applications. Moreover, a wide range of small non-obtrusive single-lead ECG ambulatory monitoring devices are now available, from which heart rate variability (HRV) and other health-related metrics are derived. Proper beat detection and classification of abnormal rhythms is important for reliable HRV assessment and can be challenging in single-lead ECG monitoring devices...

In most tropical areas, pregnant women are at increased risk of malaria, as a consequence of the massive sequestration of parasitized red blood cells in the placenta. The placenta plays a key role in embryonic and fetal development as well as in maternal-fetal exchanges, and pregnancy-associated malaria may alter selected placenta functions that lead to stillbirth and low birth weight. Although there are several tools (blood smear examination, RDT, PCR) to diagnose malaria infection during pregnancy, there is currently no test to assess placenta dysfunction in the framework of pregnancy-associated malaria...

We describe a rare case of heterotopic pregnancy following in vitro fertilization with transferring of two embryos in a 39-year-old woman with previous bilateral salpingectomy. An ultrasound examination was performed on the day before admission showing a vital intrauterine pregnancy and no ectopic pregnancy. The woman was admitted with a ruptured cornual pregnancy at ten weeks of gestation. Laparotomy was performed on vital indication with excision of the ruptured haemorrhagic cornual pregnancy. The intrauterine pregnancy continued uneventfully with obstetric and fetal medicine specialist monitoring...

STUDY QUESTION: Is diethylstilbestrol (DES), a prototypical endocrine-disrupting chemical (EDC), able to induce physiological changes in human spermatozoa and affect progesterone actions? SUMMARY ANSWER: DES promoted Ca(2+) flux into human spermatozoa by activating the cation channel of sperm (CatSper) and suppressed progesterone-induced Ca(2+) signaling, tyrosine phosphorylation and sperm functions. WHAT IS KNOWN ALREADY: DES significantly impairs the male reproductive system both in fetal and postnatal exposure...

Neonatal arterial ischemic stroke (NAIS) is a rare event that occurs in approximately one in 5000 term or close-to-term infants. Most affected infants will present with seizures. Although a well-recognized clinical entity, many questions remain regarding diagnosis, risk factors, treatment, and follow-up modalities. In the absence of a known pathophysiological mechanism and lack of evidence-based guidelines, only supportive care is currently provided. To address these issues, a French national committee set up by the French Neonatal Society (Société française de néonatologie) and the national referral center (Centre national de référence) for arterial ischemic stroke in children drew up guidelines based on an HAS (Haute Autorité de santé [HAS]; French national authority for health) methodology...

Chronic hypertension affects up to 5% of pregnancies. Women can be stratified into low-risk or high-risk chronic hypertension based on baseline laboratory and diagnostic work-up, comorbid conditions, and outcomes in prior pregnancies. Pregnancies complicated by chronic hypertension are at risk for increased adverse maternal and neonatal outcomes including superimposed preeclampsia, fetal growth restriction, placental abruption, and perinatal death. Mainstays of management include blood pressure control, close monitoring for development of superimposed preeclampsia, serial ultrasound assessment of fetal growth, and antenatal testing after 32 weeks...

Natural human embryonic mortality is generally considered to be high. Values of 70% and higher are widely cited. However, it is difficult to determine accurately owing to an absence of direct data quantifying embryo loss between fertilisation and implantation. The best available data for quantifying pregnancy loss come from three published prospective studies (Wilcox, Zinaman and Wang) with daily cycle by cycle monitoring of human chorionic gonadotrophin (hCG) in women attempting to conceive. Declining conception rates cycle by cycle in these studies indicate that a proportion of the study participants were sub-fertile...

INTRODUCTION: Obstructive uropathies are main diseases affecting the fetus. Early diagnosis allows to establish the appropriate therapy to minimize the risk of damage to kidney function at birth. Biochemical markers have been used to predict the prognosis of renal function in fetuses. Uromodulin, also known by Tamm-Horsfall protein (THP) is exclusively produced in the kidneys and in normal conditions is the protein excreted in larger amounts in human urine. It plays important roles in kidneys and urinary tract...

Fetal and neonatal autoimmune hyperthyroidism is a rare, serious but transient disorder. Early diagnosis and treatment are key objectives for an optimal prognosis and the well-being of the child. This review focuses on the management of these patients during the fetal and neonatal periods. We propose a diagnostic algorithm for high-risk pregnancies in mothers with current or past hyperthyroidism related to Graves' disease, involving repeated fetal thyroid gland assessments from 20 weeks of gestation onwards and maternal serum thyroid-stimulating hormone receptor antibody (TRAb) determination, with close monitoring if TRAb levels exceed 2 to 3 times the upper limit of the normal range...
