RESUMEN
AIM: The study aims to determine the risk factors associated with mortality and necrotising enterocolitis (NEC) among very low birthweight infants in 95 neonatal intensive care units in the Asian Network on Maternal and Newborn Health. METHODS: This is a cross-sectional study using an international collaborative database of 17,595 very low birthweight infants admitted within 28 days of birth between 2003 and 2006 in four Asian countries. Information on the mortality and morbidity of neonates admitted to the neonatal intensive care units was recorded. Factors associated with the death and diseases of infants were estimated using multilevel multivariate logistic regression. Random effects were included to account for the clustering of the observations. RESULTS: Overall discharge mortality was 15% and it was significantly different by countries and units. The mortality rate was found to be significantly higher in neonates with pulmonary haemorrhage (odds ratio 1.83, 95% confidence interval 1.63-2.04) and air leak syndrome (odds ratio 1.51, 95% confidence interval 1.30-1.72). The incidence of NEC was 4.3% and was strongly associated with other morbidities. Multivariate logistic regression showed that patent ductus arteriosus was the most significant risk factor associated with NEC. CONCLUSIONS: Our analysis has highlighted the great potential that multi-country, collaborative datasets have in terms of epidemiologic research when it comes to identifying issues in perinatal health that are common throughout Asia, and in relation to particular issues pertaining to specific countries and neonatal units. Establishing collaborative networks, conducting analyses of common datasets and further epidemiologic research are now essential measures to improve newborn health in Asia.

Second-hand smoke (SHS) has adverse effects for pregnant women and foetuses. This controlled and randomized clinical trial evaluated the efficacy of a comic booklet intervention in promoting SHS avoidance among pregnant women and appropriate smoking behaviours among their male partners. We allocated 140 couples to the experimental group (EG), who received the comic booklet and a reminder sticker, and 146 couples to the control group (CG), who received usual care. The primary outcomes were women's self-reported SHS exposure and their male partners' smoking behaviours. Secondary outcomes included knowledge and awareness of SHS. Independent t-tests revealed that three months post-intervention, more male partners in the EG had appropriate self-reported smoking behaviours with a small effect size (Cohen's d = 0.35, 95% CI [0.08, 0.62], p-value = 0.01). Significantly more pregnant women in the EG recognised their partners' appropriate smoking behaviours with a nearly middle effect size (Cohen's d = 0.43, 95% CI [0.16, 0.70], p-value ≤ 0.01). Cues to action showed a significant difference between groups with a small effect size (Cohen's d = 0.36, 95% CI [0.09, 0.63], p-value = 0.01), as evaluated by male partners. These findings suggest that the comic booklet intervention might be effective against SHS exposure by providing several cues to action through knowledge and awareness of SHS.
RESUMEN
INTRODUCTION: Various interventions to prevent mother-to-child-transmission (MTCT) of HIV have been investigated and implemented. A number of systematic reviews assessing the efficacy of interventions for the prevention of MTCT of HIV reported antiretroviral prophylaxis, caesarean section before labour and before ruptured membranes, and complete avoidance of breastfeeding were efficacious for preventing MTCT of HIV. Recent WHO guidelines recommend lifelong antiretroviral therapy for all pregnant women for treatment of the woman's own HIV infection and for prevention of MTCT of HIV. Therefore, the objective of this overview is to evaluate the currently available systematic reviews of interventions for preventing MTCT of HIV, and to identify the current best evidence-based interventions for reducing the risk of MTCT of HIV. METHODS AND ANALYSIS: We will include only peer-reviewed systematic reviews of randomised or quasi-randomised controlled trials assessing the effects of interventions for preventing MTCT of HIV that target both HIV-infected women and children aged 2 years and younger born to HIV-infected women. We will search the Cochrane Database of Systematic Reviews, the Database of Abstracts of Reviews of Effectiveness, Ovid MEDLINE and EMBASE. We will assess review eligibility, the methodological quality of included systematic reviews using A Measurement Tool to Assess The Systematic Reviews and will extract data, comparing our results and resolving discrepancies by consensus. Finally, we will independently assess the certainty of the evidence using Grades of Recommendation, Assessment, Development and Evaluation. ETHICS AND DISSEMINATION: Ethics approval is not required. We will publish the results in a peer-reviewed journal and present at conferences, which will inform future research and will be useful for healthcare managers, administrators and policymakers to guide resource allocation decisions and optimisation of interventions to prevent the MTCT of HIV.
