Multicenter StudyTrends in stillbirths, early and late neonatal mortality in rural Bangladesh: the role of public health interventions.
Trends were examined in a cohort study of stillbirths and early and late neonatal deaths in Matlab, a rural area of Bangladesh between 1975 and 2002, using routinely collected demographic surveillance data. Main outcome measures were stillbirths per 1000 births, early neonatal deaths per 1000 livebirths, and late neonatal deaths per 1000 children surviving after 1 week. We performed a logistic regression examining trends over time and between two areas in the three outcome measures, controlling for the effects of parental education, religion, time, geography, parity, maternal age and birth spacing. ⋯ Adjusting for socio-economic or demographic factors did not substantially alter the time or area differentials. The dramatic decline in neonatal mortality was, in large part, due to a fall in deaths from neonatal tetanus. The pace of decline was faster in the area receiving intense maternal and child health and family planning interventions, but stillbirths, early and late neonatal deaths also declined in the area not receiving such intense attention, suggesting that factors outside the formal health sector play an important role.

Active and passive maternal smoking during pregnancy and the risks of low birthweight and preterm birth: the Generation R Study.
The objective of this study was to examine the associations between active and passive smoking in different periods of pregnancy and changing smoking habits during pregnancy, with low birthweight and preterm birth. The study was embedded in the Generation R Study, a population-based prospective cohort study from early fetal life onwards in Rotterdam, The Netherlands. Active and passive smoking were assessed by questionnaires in early, mid- and late pregnancy. ⋯ This study shows that active and passive smoking in late pregnancy are associated with adverse effects on weight and gestational age at birth. Smoking in early pregnancy only, seems not to affect fetal growth adversely. Health care strategies for pregnant women should be aimed at quitting smoking completely rather than reducing the number of cigarettes.

Strategies for improving the quality of health care in maternal and child health in low- and middle-income countries: an overview of systematic reviews.
There are many systematic reviews of continuing education programmes and educational strategies for quality improvement in health care. Most of the reviewed studies are one-off evaluations rather than impact evaluations with long-term follow-up. There are few systematic reviews of organisational, financial and regulatory interventions, and few high-quality studies. ⋯ Interventions should be selected or tailored to address the underlying reasons for a failure to deliver effective services. Decision-makers should select the most appropriate interventions for specific problems. This requires a governance structure that clearly assigns responsibility for quality-improvement activities, priority setting, selection and design of interventions, and evaluation.

Updating reviews: the experience of the Cochrane Neonatal Review Group.
Maintaining updated systematic reviews is one of the key goals of the Cochrane Collaboration. Reviews are meant to be updated at an interval of no more than 2 years. ⋯ However, this means that the CNRG now has a more urgent need to address the issue of review updates. In order to do so, the CNRG has sought methods to prioritize and facilitate the review process.

Multicenter Study Comparative StudyClinical and economic outcomes for term infants associated with increasing administration of antibiotics to their mothers.
Implementation of national guidelines for the prevention of group B streptococcal (GBS) infections has led to an increase in intrapartum antibiotic use and reduction in early-onset GBS infections in newborns. Other outcomes, including the clinical diagnosis of sepsis in term infants, treatment with antibiotics, length of stay, and cost have not been described. To examine these outcomes, we performed an analysis of maternal and newborn data collected between 1998 and 2002 of 130 447 in-hospital births of newborns >or=37 weeks gestation and their mothers from a large vertically integrated healthcare organisation in Utah. ⋯ After controlling for maternal chorioamnionitis, delivery by caesarean section and maternal GBS status, newborns of mothers who received antibiotics were significantly more likely to be treated for clinical sepsis than were newborns of mothers who had not received them [adjusted OR = 3.3; 95% CI 2.9, 3.8]. The average length of stay for newborns whose mothers were treated with antibiotics was 55.8 h compared with 41.6 h for those not treated (P < 0.0001). The cost of caring for newborns whose mothers received antibiotics was $740 compared with $638 for those whose mothers had not received them (P < 0.001).
