Preeclampsia – abnormal uterine artery Doppler is related to recurrence of symptoms during the next pregnancy

Background: Impaired trophoblast invasion is suggested as the main cause of reduced placental perfusion, which results in fetal growth restriction and preeclampsia...

Keywords: Doppler, placenta, preeclampsia, pregnancy, recurrence, uterine artery

Fetal and maternal Doppler velocimetry and cytokines in high-risk pregnancy

Objective: Fetal hypoxia and preterm delivery are reported to be strongly associated with brain damage and neurodevelopmental delay...

Keywords: Brain damage, Doppler velocimetry, fetus, Interleukin-6, placenta, tumor necrosis factor-?

Placental pathology and pregnancy outcomes in donor and non-donor oocyte in vitro fertilization pregnancies

Objective: Intrinsically poor maternal adaptation to pregnancy and dysregulated processes have been postulated to occur as a consequence of an immune response to the feto-placental unit as “foreign” material...

Keywords: Immune, in vitro fertilization, pathology, placenta, pregnancy outcomes

Fetal brain sparing is strongly related to the degree of increased placental vascular impedance

Background: Doppler ultrasound examination has become an established method of clinical surveillance in high-risk pregnancies...

Keywords: Brain-sparing, Doppler, fetus, middle cerebral artery, placenta, pregnancy

Umbilical artery pulsatility index: reliability at different sampling sites

Objectives: To analyse the inter-observer and inter-artery reliability of the umbilical artery (UA) pulsatility index (PI) at different sampling sites.

Methods: One hundred consecutive singleton pregnancies between 24 and 40 weeks were included...

Keywords: circulation, Doppler, fetus, placenta, reliability analysis, umbilical artery

Examining the relationship between positive mid-gestational fetal fibronectin assays and histological evidence of acute placental inflammation

Aims: Both acute placental inflammation and positive mid-gestational cervico-vaginal fetal fibronectin assays have been independently correlated with preterm delivery...

Keywords: Chorioamnionitis, fetal fibronectin, infection, placenta, preterm birth

The Northwestern twin chorionicity study: testing the ‘placental crowding’ hypothesis

Objective: To evaluate the relation between placental proximity and frequency of birth weight discordance and small-for-gestational age (SGA) infants.

Study design: Retrospective three-tier chorionicity analysis of 1155 twin placentas comparing birth weight characteristics of the twins in different placental types.

Results: Dichorionic-separate, but not dichorionic-fused twins, are heavier than monochorionic-diamniotic and monoamniotic twins (2376±721 vs...

Keywords: Birth weight, chorionicity, discordance, placenta, Twins

The fetus, not the mother, elicits maternal immunologic rejection: lessons from discordant dizygotic twin placentas

Aims: Our objective was to elucidate the pathogenesis of twin discordance in four dizygotic pregnancies where only one of the twins had IUGR due to chronic villitis.

Methods: We identified four cases of dizygotic twin placentas over a period of four years with evidence of chronic villitis...

Keywords: Dizygotic, fetus, IUGR, maternal immunologic rejection, placenta, twin, villitis
