There is strong evidence that the incidence of venous thromboembolism (VTE) is increased during pregnancy. However, it is unknown whether and to which extent pregnancy influences the risk for recurrent VTE in women with previous thrombosis. To investigate whether pregnancy temporarily increases the risk for recurrent thrombosis, we retrospectively evaluated the recurrence rate in 109 women who ...

BACKGROUND Case series have described aortic dissection and rupture in pregnancy. Few population-based data exist to support an association. METHODS We performed a cohort-crossover study using data on all emergency department visits and acute care hospitalizations at nonfederal healthcare facilities in California, Florida, and New York. We included women ≥12 years of age with labor and delive...

Using high-quality longitudinal data on 125,720 singleton live births in Matlab, Bangladesh, we assessed the effects of duration of intervals between pregnancy outcomes on infant and child mortality and how these effects vary over subperiods of infancy and childhood and by the type of outcome that began the interval. Controlling for other correlates of infant and child mortality, we find that s...

OBJECTIVE To examine whether depressive symptoms are a risk factor for a subsequent pregnancy in adolescent mothers. DESIGN Secondary analysis from a longitudinal risk-reduction intervention. SETTING Five community-based prenatal sites in Baltimore, Maryland. PARTICIPANTS Two hundred sixty-nine consenting teens, predominantly African American and with low income, who received prenatal car...

OBJECTIVE To establish the role of clinical chorioamnionitis as an independent risk factor for recurrence in a subsequent pregnancy. METHOD This was a historical cohort study of pregnant women who had their first and second deliveries at our institution between January 1988 and May 2005. The index pregnancy was restricted to those who delivered vaginally. Data were collected from a continuous...

Background Preconception care means interventions required for maternal and fetal health care and detection of pre-pregnancy risk factors. Some risk factors that have a significant effect on the outcome of pregnancy can be detected and controlled before pregnancy. The present study aimed to determine the prevalence of pre-pregnancy risk factors, and its relationship with preconception care in I...

BACKGROUND Offspring of women with hypertensive disorders of pregnancy are at increased risk of cardiovascular complications later in life, but the mechanisms underlying these associations are unclear. Our aim was to examine whether adjusting for birth weight and familial adiposity changed the association of hypertensive disorders of pregnancy with offspring blood pressure. METHODS AND RESULT...
