Severe maternal morbidity associated with hypertensive disorders in pregnancy in the United States
ABSTRACT This study was to report the incidence of severe maternal morbidity associated with hypertensive disorders of pregnancy in the United States.
We used data from the National Hospital Discharge Survey, a nationally representative sample of discharge records, from 1988 to 1997. The database consisted of approximately 300,000 deliveries, which represented 39 million births during the 10-year period.
The overall incidence of hypertensive disorders in pregnancy was 5.9% [95% confidence interval (CI): 5.2 to 6.5%]. Eclampsia was reported at 1.0 per 1,000 deliveries (95% CI: 0.8 to 1.2). The incidence of eclampsia, severe preeclampsia, and superimposed preeclampsia remained unchanged during the 10-year period. Women with preeclampsia and eclampsia had a 3- to 25-fold increased risk of severe complications, such as abruptio placentae, thrombocytopenia, disseminated intravascular coagulation, pulmonary edema, and aspiration pneumonia. More than half of women with preeclampsia and eclampsia had cesarean delivery. African American women not only had higher incidence of hypertensive disorders in pregnancy but also tended to have a greater risk for most severe complications. Preeclamptic and eclamptic women younger than 20 years or older than 35 years had substantially higher morbidity.
Preeclampsia and eclampsia carry a high risk for severe maternal morbidity. Compared to Caucasians, African Americans have higher incidence of hypertensive disorders in pregnancy and suffer from more severe complications.

ABSTRACT: The time of pregnancy, birth, and lactation, is characterized by numerous specific alterations in several systems of the maternal body. Peripartum-associated changes in physiology and behavior, as well as their underlying molecular mechanisms, have been the focus of research since decades, but are still far from being entirely understood. Also, there is growing evidence that pregnancy and lactation are associated with a variety of alterations in neural plasticity, including adult neurogenesis, functional and structural synaptic plasticity, and dendritic remodeling in different brain regions. All of the mentioned changes are not only believed to be a prerequisite for the proper fetal and neonatal development, but moreover to be crucial for the physiological and mental health of the mother. The underlying mechanisms apparently need to be under tight control, since in cases of dysregulation, a certain percentage of women develop disorders like preeclampsia or postpartum mood and anxiety disorders during the course of pregnancy and lactation. This review describes common peripartum adaptations in physiology and behavior. Moreover, it concentrates on different forms of peripartum-associated plasticity including changes in neurogenesis and their possible underlying molecular mechanisms. Finally, consequences of malfunction in those systems are discussed.Neural Plasticity 05/2014; 2014:574159. DOI:10.1155/2014/574159 · 3.60 Impact Factor

ABSTRACT: Preeclampsia (PE) is hypertension with proteinuria that develops during pregnancy and affects at least 5% of pregnancies. The Effect of Folic Acid Supplementation in Pregnancy on Preeclampsia: the Folic Acid Clinical Trial (FACT) aims to recruit 3,656 high risk women to evaluate a new prevention strategy for PE: supplementation of folic acid throughout pregnancy. Pregnant women with increased risk of developing PE presenting to a trial participating center between 8(0/7) and 16(6/7) weeks of gestation are randomized in a 1 : 1 ratio to folic acid 4.0 mg or placebo after written consent is obtained. Intent-to-treat population will be analyzed. The FACT study was funded by the Canadian Institutes of Health Research in 2009, and regulatory approval from Health Canada was obtained in 2010. A web-based randomization system and electronic data collection system provide the platform for participating centers to randomize their eligible participants and enter data in real time. To date we have twenty participating Canadian centers, of which eighteen are actively recruiting, and seven participating Australian centers, of which two are actively recruiting. Recruitment in Argentina, UK, Netherlands, Brazil, West Indies, and United States is expected to begin by the second or third quarter of 2013. This trial is registered with NCT01355159.Journal of pregnancy 01/2013; 2013:294312. DOI:10.1155/2013/294312
