Abstract Objective: Hypertensive diseases in pregnancy (HDP) occur in 5-8% of all pregnancies and represent one of the most important causes of maternal and fetal morbidity. Even after a normal pregnancy/delivery adaptation to parenthood is a major challenge. However, a successful adjustment is important for future family health. As pregnancy ...

Clinical Problem Twin-to-twin transfusion syndrome (TTTS) increases perinatal morbidity and mortality for 10 to 15% of monochorionic (MC) gestations. Pathophysiology MC gestations are at risk due to the angioarchitecture of the shared placenta, with anastomoses of varying type, size, and quantity. TTTS results from progression of a chronic perfusion imbalance across unbalanced ...

Twin anemia-polycythemia sequence (TAPS) is a recently described complication of monochorionic placentation characterized by discordance in hemoglobin (Hgb) levels in the absence of amniotic fluid abnormality characteristic of classical twin-twin transfusion syndrome (TTTS). The placental angioarchitecture that predisposes to TAPS consists of small diameter arteriovenous anastomoses and the absence of ...

Exposure to poor maternal nutrition around the time of conception results in an early prepartum activation of the fetal pituitary-adrenal axis and in increased adrenal growth and stress response after birth associated with epigenetic changes in a differentially methylated region (DMR) of adrenal IGF2/H19. We have determined the effects of ...

Monozygotic twinning, associated with increased infant morbidity and mortality, is more common after assisted reproductive technology (ART) than in the general population. Although multiple factors have been proposed as contributors, studies seeking to define causality have been underpowered or inconclusive. We evaluated trends of monozygotic twinning in ART and its ...

Introduction: Cytokine imbalance has been implicated in placental-related pathologies, i.e. recurrent miscarriage and pre-eclampsia. Such conditions are more prevalent in multiple pregnancies. Twin-to-twin transfusion syndrome (TTTS) is associated with asymmetric placental blood flow and intra-cardiac pressures. We hypothesised that cytokine expression may be aberrant in this condition and that fetoscopic ...
