Many elements of routine prenatal care are based on tradition and lack a firm evidence base; however, some elements are supported by more rigorous studies. Correct dating of the pregnancy is critical to prevent unnecessary inductions and to allow for accurate treatment of preterm labor. Physicians should recommend folic acid supplementation to all women as early as possible, preferably before conception, to reduce the risk of neural tube defects. Administration of Rho(D) immune globulin markedly decreases the risk of alloimmunization in an RhD-negative woman carrying an RhD-positive fetus. Screening and treatment for iron deficiency anemia can reduce the risks of preterm labor, intrauterine growth retardation, and perinatal depression. Testing for aneuploidy and neural tube defects should be offered to all pregnant women with a discussion of the risks and benefits. Specific genetic testing should be based on the family histories of the patient and her partner. Physicians should recommend that pregnant women receive a vaccination for influenza, be screened for asymptomatic bacteriuria, and be tested for sexually transmitted infections. Testing for group B streptococcus should be performed between 35 and 37 weeks' gestation. If test results are positive or the patient has a history of group B streptococcus bacteriuria during pregnancy, intrapartum antibiotic prophylaxis should be administered to reduce the risk of infection in the infant. Intramuscular or vaginal progesterone should be considered in women with a history of spontaneous preterm labor, preterm premature rupture of membranes, or shortened cervical length (less than 2.5 cm). Screening for diabetes should be offered using a universal or a risk-based approach. Women at risk of preeclampsia should be offered low-dose aspirin prophylaxis, as well as calcium supplementation if dietary calcium intake is low. Induction of labor may be considered between 41 and 42 weeks' gestation.

Hepatic hepcidin synthesis is stimulated by inflammation but inhibited during iron deficiency anemia (IDA). In humans, the relative strength of these opposing signals on serum hepcidin and the net effect on iron absorption and systemic iron recycling is uncertain. In this prospective, 45-day study, in young women (n=46; age 18-49 years) with or without IDA, we compared iron and inflammation markers, serum hepcidin and erythrocyte iron incorporation from 57Fe-labeled test meals, before and 8, 24 and 36 hours (h) after influenza/DPT vaccination as an acute inflammatory stimulus. Compared to baseline, at 24-36 h after vaccination: 1) interleukin-6 increased 2-3-fold in both groups (P<0.001); 2) serum hepcidin increased >2-fold in the non-anemic group (P<0.001), but did not significantly change in the IDA group; 3) serum iron decreased in the non-anemic group (P<0.05) but did not change in the IDA group; and 4) erythrocyte iron incorporation did not change in either of the two groups, but was approximately 2-fold higher in the IDA group both before and after vaccination (P<0.001). In this study, mild acute inflammation did not increase serum hepcidin in women with IDA, suggesting low iron status and erythropoietic drive offset the inflammatory stimulus on hepcidin expression. In non-anemic women, inflammation increased serum hepcidin and produced mild hypoferremia, but did not reduce dietary iron absorption, suggesting iron-recycling macrophages are more sensitive than the enterocyte to high serum hepcidin during inflammation. The study was registered as a prospective observational trial at clinicaltrials.gov identifier: 02175888 The study was funded by the International Atomic Energy Agency.
