Updated USPSTF and CDC recommendations, and incorrect Cochrane review data. Based on new and additional recommendations, we are updating the article “Update on Prenatal Care” (February 1, 2014, p. 199). The U.S. Preventive Services Task Force (USPSTF) updated their recommendations in January 2014 regarding screening for diabetes mellitus in pregnant women. Therefore, the third to the last sentence in the abstract (p. 199), the ninth statement in the SORT table (p. 206), and text in the second paragraph under the “Gestational Diabetes” header (p. 206) have been revised to indicate that the USPSTF recommends that all pregnant women be screened for diabetes between 24 and 28 weeks' gestation. Based on 2012 recommendations from the Centers for Disease Control and Prevention (CDC), the third row in Table 5 (p. 205) should not have included cefixime (Suprax) as a treatment option for gonorrhea. Because incorrect data from a Cochrane review (reference 66) were cited, the last three sentences of the first paragraph under the “Postterm Pregnancy” header (p. 207) should have updated rates of perinatal death and operative vaginal delivery. The online version of this article has been corrected.
