Objective To assess patterns of e-health use in pregnancy in an underserved racially diverse inner-city population, and to assess the accuracy of pregnancy-related information obtained from the Internet. Methods A cross sectional study of 503 pregnant/postpartum women belonging to an underserved racially diverse inner-city population who completed a survey regarding e-health use. To assess accuracy, four independent expert-reviewers rated the first 10 webpages on Google searches for each of five questions based upon those in ACOG bulletins. Results 70.8 % of pregnant/postpartum women belonging to an underserved racially diverse inner-city population were e-health users. E-health users were younger (mean age 29.4 vs. 31.2, P = 0.009), more likely to be nulliparous (50.3 vs. 21.3 %, P < 0.001), have English as their primary language (62.3 vs. 49.1 %, P = 0.014) and have a college/graduate education (78 vs. 26.6 %, P < 0.001). While 60 % of these women said e-health influenced decision making, only 71.3 % of them discussed their searches with their provider. Expert reviewers determined that the online information was fairly accurate (mean score: +1.48 to +4.33 on a scale of -5 to +5) but not uniformly accurate, and there was at least one webpage with inaccurate information for every question. Conclusions for practice Pregnant women frequently use e-health resources but do not routinely share their findings with their providers. Most, but not all, information obtained is accurate. Therefore it is important for providers to discuss their patients' use, and help to guide them to reliable information.

The pathophysiology of cervical artery dissection appears multifactorial, with evidence suggesting environmental and genetic contributions. Intimal injury related to the Valsalva maneuver during labor as well as hemodynamic and hormonal changes related to pregnancy are presumed causes of peripartum spontaneous carotid artery dissection. Antithrombotic therapy for at least 3 to 6 months after dissection and follow-up neuroimaging are suggested.

Purpose of review Little consensus exists on the definition of gestational diabetes (GDM), how the condition should diagnosed, and if interventions for mild maternal hyperglycemia are of any benefit to the mother or fetus. Today, after several large multi-center clinical trials, we are closer than ever to a national and international consensus. Recent findings Glucose tolerance in pregnancy is a continuum, which has a fundamental link to fetal growth. The relationship between maternal glycemia and adverse outcomes is continuous, with no distinct inflection point for increased risk. As a result, any cutoff for the diagnosis of GDM is somewhat arbitrary. Treatment for GDM, even mild cases, significantly reduces the rate of certain adverse perinatal and maternal outcomes, warranting intervention. Summary Clinical guidelines for the diagnosis of GDM are expected to change in the near future provided that recommendations from the International Association of Diabetes and Pregnancy Study Group (IADPSG) are accepted by professional organizations. The criteria for the diagnosis will likely be based on a single 75g, 2-hour oral glucose tolerance test with at least one abnormal value. The proposed threshold values are based on an international consensus regarding risk of adverse pregnancy outcomes. The public health implications for these changes are anticipated to be significant.
