Comparative StudyThe role of antenatal corticosteroids in twin pregnancies complicated by preterm birth.
Data regarding the effects of antenatal corticosteroids in twin pregnancies are limited because of the insufficient number of women with twins enrolled in randomized controlled trials on antenatal corticosteroids. Furthermore, the interpretation of available data is limited by the fact that the interval from the administration of antenatal corticosteroids to delivery is greater than 7 days in a large proportion of twins, a factor that has been shown to affect the efficacy of antenatal corticosteroids and has not been controlled for in previous studies. ⋯ Administration of a complete course of antenatal corticosteroids 1-7 days before birth in twin pregnancies is associated with a clinically significant decrease in neonatal mortality, short-term respiratory morbidity, and severe neurological injury that is similar in magnitude to that observed among singletons.

Acidemia in neonates with a 5-minute Apgar score of 7 or greater - What are the outcomes?
The Apgar score is universally used for fetal assessment at the time of birth, whereas, the collection of fetal cord blood gases is performed commonly in high-risk situations or in the setting of Apgar scores of <7, which is a less standardized approach. It has been well-established that neonatal acidemia at the time of delivery can result in significant neonatal morbidity and death. Because of this association, knowledge of the fetal acid-base status and detection of acidemia at the time of delivery can serve as a sensitive and useful component in the assessment of a neonate's risk. Umbilical cord blood gas analysis is an accurate and validated tool for the assessment of neonatal acidemia at the time of delivery. Because the collection of fetal cord blood gases is not a standardized practice, it is possible that, with such a varied approach, some cases of neonatal acidemia are not detected, particularly in the setting of reassuring Apgar scores. ⋯ Because neonates with reassuring Apgar scores have a residual risk of neonatal acidemia that is associated with higher rates of adverse outcomes, the potential utility of obtaining universal cord blood gases should be further investigated.

Trends in hospitalizations of pregnant HIV-infected women in the United States: 2004 through 2011.
With the development and widespread use of combination antiretroviral therapy, HIV-infected women live longer, healthier lives. Previous research has shown that, since the adoption of combination antiretroviral therapy in the United States, rates of morbidity and adverse obstetric outcomes remained higher for HIV-infected pregnant women compared with HIV-uninfected pregnant women. Monitoring trends in the outcomes these women experience is essential, as recommendations for this special population continue to evolve with the progress of HIV treatment and prevention options. ⋯ The numbers of hospitalizations during pregnancy and delivery have not increased for HIV-infected women since 2004, a departure from previously estimated trends. Pregnancy hospitalizations of HIV-infected women remain more medically complex than those of HIV-uninfected women. An increasing trend in infections among the delivery hospitalizations of HIV-infected pregnant women warrant further attention.

Randomized Controlled Trial Comparative StudyComparison of suture materials for subcuticular skin closure at cesarean delivery.
Subcuticular skin closure with suture after cesarean has been shown to result in lower rates of wound complications than with staple closure. However, the optimal choice of suture material for subcuticular skin closure is unclear. Vicryl (a braided multifilament synthetic suture; Ethicon, Somerville, NJ) and Monocryl (a monofilament synthetic suture; Ethicon) are the commonly used suture materials for subcuticular closure of transverse skin incisions after cesarean in the United States. Whereas in vitro and animal studies suggest multifilament suture materials may be associated with a higher risk of wound infection than monofilament sutures, clinical data on their relative effectiveness are limited. ⋯ Subcuticular skin closure with 4-0 Vicryl is associated with comparable rates of surgical site infection and other wound complications as 4-0 Monocryl. While this is an observational study with the potential for selection bias and residual confounding, our results suggest physician preference is acceptable for choice of subcuticular suture material at cesarean.

Maternal and neonatal outcomes of attempted vaginal compared with planned cesarean delivery in triplet gestations.
The prevailing obstetric practice of planned cesarean delivery for triplet gestations is largely empiric and data on the optimal route of delivery are limited. ⋯ In a multicenter US cohort, attempted vaginal delivery of triplets is associated with higher risks of maternal transfusion and neonatal mechanical ventilation. Composite severe neonatal morbidity may be higher with attempted vaginal delivery although studies with greater power are required. The low probability of successful vaginal delivery raises questions regarding the utility of attempted vaginal delivery in triplet gestations. Our data support planned prelabor cesarean delivery as the preferred mode of delivery for triplet gestations.
