OBJECTIVE: To compare first trimester 2D conventional and 3D power Doppler angiography measures in twins and singletons following assisted reproduction. METHODS: We prospectively evaluated 50 singleton and 47 twin pregnancies that eventually ended in live births. Patients were recruited from a single assisted reproductive technology (ART) center with standard treatment protocols. Obstetric ultrasound was performed at 8-9 weeks +6 days. Intervillous flow, uteroplacental circulation and uterine artery pulsatility (PI) and resistance index (RI) using two-dimensional (2D) ultrasound examination were evaluated...

BACKGROUND: Lipid peroxidation mediated by reactive oxygen species is a major contributor to oxidative stress. Docosahexaenoic acid (DHA) has anti-oxidant and neuroprotective properties. Our objective was to assess how oxidative stress measured by lipid peroxidation was modified by DHA in a newborn piglet model of hypoxia-ischemia (HI). METHODS: Fifty-five piglets were randomized to (i) hypoxia, (ii) DHA, (iii) hypothermia, (iv) hypothermia+DHA or (v) sham. All groups but sham were subjected to hypoxia by breathing 8% O2...

BACKGROUND: Lactic acid dehydrogenase (LDH) is a valuable marker for some of the most important diseases in newborns and the plasma LDH activity in newborns correlates well with conditions such as asphyxia. If LDH should be considered as a useful tool also in obstetric care, key factors associated with maternal health before and during pregnancy which could affect umbilical cord LDH activity need to be known. The aims of this study were to explore relationships between selected maternal conditions and arterial lactic acid dehydrogenase activity (aLDH) in umbilical cord blood at delivery...

INTRODUCTION: Epidural analgesia has been considered a risk factor for labor dystocia at trial of labor after cesarean (TOLAC) and uterine rupture. We evaluated the association between exposure to epidural during TOLAC and mode of delivery and maternal-neonatal outcomes. MATERIALS AND METHODS: A single center retrospective study of women that consented to TOLAC within a strict protocol between 2006 and 2013. Epidural "users" were compared to "non-users". Primary outcome was the mode of delivery: repeat in-labor cesarean or vaginal birth after cesarean (VBAC)...

INTRODUCTION: The incidence of venous thromboembolism (VTE) after cesarean section is up to 0.6%, and the widespread use of cesarean section draws attention to this group. The dosage and duration of low-molecular-weight heparin (LMWH) prophylaxis after delivery is estimated by anamnestic risk-scales; however, the predictive potency for an individual patient's risk can be low. Laboratory hemostasis assays are expected to solve this problem. The aim of this study was to estimate the potency of tests to reflect the coagulation state of patients receiving LMWH in the early postpartum period...

AIM: Ureaplasma parvum, Ureaplasma urealyticum and Mycoplasma hominis are also known as genital mycoplasmas. Acute chorioamnionitis is an inflammation of the placenta associated with miscarriage. We retrospectively evaluated a possible association between genital mycoplasmas detection, acute chorioamnionitis and fetal pneumonia from second and third trimester spontaneous abortions. METHODS: One hundred and thirty placenta and fetal lung samples were evaluated for histological examination...

The identification of congenital birth defects and fetal malformations continues to increase during the antenatal period with improved imaging techniques. Understanding of how to treat specific fetal conditions continues to improve outcomes from these treatment modalities. In an effort to further improvement in this field, we provide a review that begins with a brief background of fetal surgery including the history of fetal surgery, ethics surrounding fetal surgery, and considerations of how to treat the fetus during intervention...

REVIEW
Michael Obladen
Theories about fetal respiration began in antiquity. Aristotle characterized pneuma as warm air, but also as the enabler of vital functions and instrument of the soul. In Galen's system of physiology, the vital spirit was carried by the umbilical arteries, the nutrients by the umbilical vein from the placenta to the fetus. In 1569 Aranzio postulated that the maternal and fetal vasculatures are distinct. From 1670 to 1690, a century before the discovery of oxygen, researchers understood that during respiration some form of exchange with the air must occur, naming the substance biolychnium, phlogiston, sal-nitro, or nitro-aerial particles...

Michael Obladen
The means of fetal nutrition has been debated for over two millennia, with the controversy of oral versus parenteral nutrition already in the Corpus Hippocraticum. In 1587 Aranzio rejected connections between maternal and fetal blood vessels, and coined the term "hepar uterinum" for the placenta. From the 16th to the 18th century, a fervent debate focused on the type and extent of connection between maternal and fetal vessels, which was finally settled by Hunter's injection experiment in 1774. But up to the middle of the 19th century, an important nutritive function was attributed to amniotic fluid...

OBJECTIVE: Our main objective was to study the influence on birth and ultrasound fetal weight of traditional factors in combination with non-traditionally explored predictors such as paternal height to provide a new customized in utero growth model. We also have compared it in our population with other customized and non-customized models. METHODS: We collected 5243 cases of singleton pregnancies. An integrated study of the different variables was performed in a multivariate model to predict the fetus birthweight and customized growth curves were created following the Gardosi procedure...

With all of our present knowledge, high technology diagnostic equipment, electronic databases and other available supporting resources, detection of fetal syndromes is still a challenge for healthcare providers in prenatal as well as in the postnatal period. Prenatal diagnosis of fetal syndromes is not straightforward, and it is a difficult puzzle that needs to be assembled and solved. Detection of one anomaly should always raise a suspicion of the existence of more anomalies, and can be a trigger to investigate further and raise awareness of possible syndromes...

Assessment of fetal neurobehavior and detection of neurological impairment prenatally has been a great challenge in perinatal medicine. The evolution of four-dimensional (4D) ultrasound not only enabled a better visualization of fetal anatomy but also allowed the study of fetal behavior in real time. Kurjak Antenatal Neurodevelopmental Test (KANET) was developed for the assessment of fetal neurobehavior and the detection of neurological disorders, based on the assessment of the fetus by application of 4D ultrasound in the same way that a neonate is assessed postnatally...

REVIEW
Giuseppe Calì, Francesca Foti, Gabriella Minneci
The anomalies in placental insertion and invasion, such as placenta previa and the various forms of abnormally invasive placenta, are today a rising obstetric pathology. Two-dimensional (2D) ultrasonography is the gold standard in the diagnosis of abnormally invasive placenta (AIP), but the important feto-maternal impact of this pathology suggests the opportunity to employ all the available diagnostic techniques, such as three-dimensional (3D) power Doppler. This technique allows acquiring multiplanar images on coronal, axial and sagittal planes and with a rotational technique, it permits visualizing the placenta-bladder interface more accurately...

We examined the risk of preterm birth (PTB, <37 weeks' gestation) in a second pregnancy and analyzed the extent to which this risk varies by maternal age and race/ethnicity. The sample included nulligravida mothers in California who delivered two singletons between 2005 and 2011. Logistic regression was used to calculate the odds of PTB in the second pregnancy. Within each race/ethnicity stratum, women delivering term infants in their first pregnancy and between 25 and 34 years old for both pregnancies served as the referent group...
