Sonographic estimation of fetal weight (EFW) is important in the management of high-risk pregnancies. The possibility that increased maternal body mass index (BMI) adversely affects EFW assessments in twin pregnancies is controversial. The aim of this study was to investigate the effect of maternal BMI on the accuracy of EFW ...

The rate of multiple pregnancies is showing a significant increase in Western countries. Twin gestations should be considered a high-risk condition because they are responsible for a disproportionate amount of overall perinatal morbidity and mortality. We used a specialised ultrasound protocol based on chorionicity to monitor 44 twin pregnancies (61% ...

Excessive pregnancy weight gain is associated with obesity in the offspring, but this relationship may be confounded by genetic and other shared influences. We aimed to examine the association of pregnancy weight gain with body mass index (BMI) in the offspring, using a within-family design to minimize confounding. In this ...

Maternal stress during pregnancy is associated with a modestly increased risk of fetal growth restriction and pre-eclampsia. Since placental abruption shares similar pathophysiological mechanisms and risk factors with fetal growth restriction and pre-eclampsia, we hypothesized that maternal stress may be implicated in abruption risk. We investigated the association between maternal ...

High maternal pre-pregnancy body mass index (BMI) is associated with increased risk of offspring attention deficit hyperactivity disorder (ADHD). However, the role of unmeasured familial confounding for this association remains unclear. We conducted a population-based cohort study via linkage of Swedish national and regional registers to investigate maternal pre-pregnancy BMI ...

Single intrauterine fetal demise in monochorionic (MC) twins may result in acute exsanguination from the surviving twin into the low-pressure circulation of the demised co-twin through the vascular anastomoses. This may lead to severe hypoxic-ischemic injury in the surviving twin due to hypovolemia, hypotension and anemia, resulting in multiorgan damage. ...

Ectopic pregnancy is a leading cause of maternal mortality. Its incidence has progressively increased in recent years. Assisted conception techniques are associated with a significantly higher rate of ectopic pregnancies. Cervical ectopic pregnancies are very rare, accounting for < 1% of all ectopic pregnancies. A 41-year-old, Caucasian woman presented for ...
