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. ...
