Meta AnalysisContinuous labor support from labor attendant for primiparous women: a meta-analysis.
To evaluate the available literature on the effects of continuous labor support among primiparous women. ⋯ Labor support may have important positive effects on obstetric outcomes among young, disadvantaged women. Further studies on benefit relative to cost are needed before a broad-scale program is advocated.

Effect of maternal age and parity on the risk of uteroplacental bleeding disorders in pregnancy.
To examine the risk of placental abruption, placenta previa, and uterine bleeding of unknown etiology in relation to advanced maternal age and parity in a large, population-based study. ⋯ Multiparity is associated with the risk of placenta previa and, to a lesser extent, placental abruption, but not with other uterine bleeding. Increasing maternal age is associated independently with the risk of placenta previa, but not with either of the other two conditions. Finally, the increased risks of uteroplacental bleeding disorders with advanced parity among the younger women (ie, 20-25 years, parity 3+) may reflect effects of close pregnancy spacing, or confounding by unmeasured factors that characterize women who have many pregnancies at a relatively young age. Overall, the findings suggest that the three uteroplacental bleeding disorders do not share a common etiology in relation to maternal age and parity, and that placenta previa is linked to aging of the uterus and the effects of repeated pregnancies.

Comparative StudyBlood pressure patterns in normal pregnancy and in pregnancy-induced hypertension, preeclampsia, and chronic hypertension.
To compare the 24-hour blood pressure (BP) pattern in physiologic pregnancy, pregnancy-induced hypertension, preeclampsia, and chronic hypertension. ⋯ Standardized 24-hour BP monitoring during pregnancy allows quantitative and qualitative evaluations of the hypertensive status. However, if such a technique is used routinely in every clinical setting, we should establish specific thresholds of normality for pregnancy.

Forceps and vacuum delivery: a survey of North American residency programs.
To document resident instruction in operative vaginal delivery by forceps and vacuum. ⋯ Instruction in both types of operative vaginal delivery is found in most programs. The forceps are used more commonly, but vacuum is the preferred instrument in about one-third of training programs. Instruction in midpelvic delivery is offered in 64% of programs, but we noted a declining trend.
