ReviewUsing ultrasound in the clinical management of placental implantation abnormalities.
Placental implantation abnormalities, including placenta previa, placenta accreta, vasa previa, and velamentous cord insertion, can have catastrophic consequences for both mother and fetus, especially as pregnancy progresses to term. In these situations, current recommendations for management usually call for an indicated preterm delivery even in asymptomatic patients. However, the recommended gestational age(s) for delivery in asymptomatic patients are empirically determined without consideration of the recent literature regarding the usefulness of specific ultrasound findings to help individualize management. The purpose of this article is to propose literature-supported guidelines to the current opinion-based management of asymptomatic patients with placental implantation abnormalities based on relevant and specific ultrasound findings such as cervical length, distance between the internal cervical os and placenta, and placental edge thickness.

This study examined maternal and neonatal outcomes that are associated with pancreatitis in pregnancy, in particular preeclampsia. ⋯ We found that pancreatitis in pregnancy was associated with several adverse maternal outcomes; in particular, a strong association existed with preeclampsia, which has its own implications and complications surrounding pregnancy management. Pancreatitis in pregnancy was also associated with increased risk for preterm delivery but not neonatal or infant death, which is consistent with the literature.

Review Meta AnalysisPlacental implantation abnormalities and risk of preterm delivery: a systematic review and metaanalysis.
We sought to evaluate the extent of the association between placental implantation abnormalities (PIA) and preterm delivery in singleton gestations. We conducted a systematic review of English-language articles published from 1980 onward using PubMed, MEDLINE, EMBASE, CINAHL, LILACS, and Google Scholar, and by identifying studies cited in the references of published articles. Search terms were PIA defined as ≥ 1 of the following: placenta previa, placenta accreta, vasa previa, and velamentous cord insertion. ⋯ Risks of NICU admissions (RR, 4.09; 95% CI, 2.80-5.97), neonatal death (RR, 5.44; 95% CI, 3.03-9.78), and perinatal death (RR, 3.01; 95% CI, 1.41-6.43) were higher with placenta previa. Perinatal risks were also higher in patients with vasa previa (perinatal death rate RR, 4.52; 95% CI, 2.77-7.39) and velamentous cord insertion (NICU admissions [RR, 1.76; 95% CI, 1.68-1.84], small for gestational age [RR, 1.69; 95% CI, 1.56-1.82], and perinatal death [RR, 2.15; 95% CI, 1.84-2.52]). In singleton gestations, there is a strong association between PIA and preterm delivery resulting in significant perinatal morbidity and mortality.

Variation in childbirth services in California: a cross-sectional survey of childbirth hospitals.
The objective of the study was to describe the resources and activities associated with childbirth services. ⋯ Childbirth services varied widely across California hospitals. Cognizance of this variation and linkage of these data to childbirth outcomes should assist in the identification of key resources and activities that optimize the hospital environment for pregnant women and set the groundwork for identifying criteria for the provision of maternal risk-appropriate care.

Review Meta AnalysisVaginal progesterone for maintenance tocolysis: a systematic review and metaanalysis of randomized trials.
We sought to evaluate the efficacy of maintenance tocolysis with vaginal progesterone compared to control (placebo or no treatment) in singleton gestations with arrested preterm labor (PTL) in a metaanalysis of randomized controlled trials. ⋯ Maintenance tocolysis with vaginal progesterone is associated with prevention of PTB, significant prolongation of pregnancy, and lower neonatal sepsis. However, given the frequent lack of blinding and the generally poor quality of the trials, we do not currently suggest a change in clinical care of women with arrested PTL. We suggest instead well-designed placebo-controlled randomized trials to confirm the findings of our metaanalysis.
