BACKGROUND Antenatal corticosteroids for pregnant women at risk of preterm birth are among the most effective hospital-based interventions to reduce neonatal mortality. We aimed to assess the feasibility, effectiveness, and safety of a multifaceted intervention designed to increase the use of antenatal corticosteroids at all levels of health care in(More)
BACKGROUND Genetic abnormalities have been associated with 6 to 13% of stillbirths, but the true prevalence may be higher. Unlike karyotype analysis, microarray analysis does not require live cells, and it detects small deletions and duplications called copy-number variants. METHODS The Stillbirth Collaborative Research Network conducted a(More)
OBJECTIVES To develop a standardized verbal autopsy (VA) training program and evaluate whether its implementation resulted in comparable knowledge required to classify perinatal cause of death (COD) by physicians and non-physicians. METHODS Training materials, case studies, and written and mock scenarios for this VA program were developed using(More)
OBJECTIVE To compare placental lesions for stillbirth cases and live birth controls in a population-based study. METHODS Pathologic examinations were performed on placentas from singleton pregnancies using a standard protocol. Data were analyzed overall and within gestational age groups at delivery. RESULTS Placentas from 518 stillbirths and 1,200 live(More)
The Stillbirth Collaborative Research Network (SCRN) was organized to study the scope and causes of stillbirth (SB) in the United States. The objective of this report is to describe the approach used for the placental examination performed as part of the study. The SCRN consists of a multidisciplinary team of investigators from five clinical sites, the(More)
OBJECTIVE To determine the comparability between cause of death (COD) by a single physician coder and a two-physician panel, using verbal autopsy. METHODS The study was conducted between May 2007 and June 2008. Within a week of a perinatal death in 38 rural remote communities in Guatemala, the Democratic Republic of Congo, Zambia and Pakistan, VA(More)
AIM To compare maternal and neonatal outcomes of Tibetan and Han Chinese women delivering vaginally at high altitude (3650 meters) in Lhasa, Tibet Autonomous Region, People's Republic of China. METHOD Comparative analysis of data from a prospective observational study of Tibetan (n = 938) and Han Chinese (n = 146) women delivering at three hospitals(More)
OBJECTIVE To compare illicit drug and smoking use in pregnancies with and without stillbirth. METHODS The Stillbirth Collaborative Research Network conducted a case-control study from March 2006 to September 2008, covering more than 90% of deliveries to residents of five a priori-defined geographically diverse regions. The study attempted to include all(More)
After reviewing the state of knowledge about the scope and causes of stillbirth (SB) in a special workshop sponsored by the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), the participants determined that there is little guidance regarding the best use of postmortem examination (PM) to address the pathogenesis of(More)
The Stillbirth Collaborative Research Network (SCRN) has conducted a multisite, population-based, case-control study, with prospective enrollment of stillbirths and livebirths at the time of delivery. This paper describes the general design, methods and recruitment experience. The SCRN attempted to enroll all stillbirths and a representative sample of(More)
