Group B Streptococcus (GBS) infection is a leading cause of death in newborns in developed countries. Data on burden of GBS in Asian countries is lacking. This study aimed to understand i) rate of maternal recto-vaginal GBS carriage, ii) vertical transmission of GBS as determined by culturing ear, umbilicus and nasal swabs, and iii) distribution of GBS serotypes. This prospective observational study was conducted from September 2012 to November 2013 at Kumudini Hospital, a secondary level hospital, at Mirzapur, Bangladesh...

Case-control studies are commonly used to evaluate effectiveness of licensed vaccines after deployment in public health programs. Such studies can provide policy-relevant data on vaccine performance under 'real world' conditions, contributing to the evidence base to support and sustain introduction of new vaccines. However, case-control studies do not measure the impact of vaccine introduction on disease at a population level, and are subject to bias and confounding, which may lead to inaccurate results that can misinform policy decisions...

The case-control methodology is frequently used to evaluate vaccine effectiveness post-licensure. The results of such studies provide important insight into the level of protection afforded by vaccines in a 'real world' context, and are commonly used to guide vaccine policy decisions. However, the potential for bias and confounding are important limitations to this method, and the results of a poorly conducted or incorrectly interpreted case-control study can mislead policies. In 2012, a group of experts met to review recent experience with case-control studies evaluating vaccine effectiveness; we summarize the recommendations of that group regarding best practices for data collection, analysis, and presentation of the results of case-control vaccine effectiveness studies...

Guidance is needed regarding potential extension of the WHO recommendation for cord cleansing with chlorhexidine to babies born in facilities. Among 3,223 facility-born babies from Nepal and Bangladesh, mortality was approximately halved among those allocated to the intervention clusters (10.5/1000 vs. 19.4/1000, RR=0.54; 95% CI: 0.30 - 0.97). In high-mortality settings, a single policy for home and facility births is warranted.

The 'continuum of care' is proposed as a key framework for the delivery of maternal, neonatal and child health services. This study examined the extent of dropout as well as factors associated with retention across the MNCH continuum from antenatal care (ANC), through skilled birth attendance (SBA), to postnatal care (PNC).We analyzed data from 1931 women who delivered in the preceding 2-14 months, from a two-stage cluster sampling household survey in four districts of Tanzania's Morogoro region. The survey was conducted in 2011 as a part of a baseline for an independent evaluation of a maternal health program...

BACKGROUND: Despite impressive improvements in maternal survival throughout the world, rates of antepartum complications remain high. These conditions also contribute to high rates of perinatal deaths, which include stillbirths and early neonatal deaths, but the extent is not well studied. This study examines patterns of antepartum complications and the risk of perinatal deaths associated with such complications in rural Bangladesh. METHODS: We used data on self-reported antepartum complications during the last pregnancy and corresponding pregnancy outcomes from a household survey (N = 6,285 women) conducted in Sylhet district, Bangladesh in 2006...

OBJECTIVES: In recent years, an increasing prevalence of macrolide resistance among pneumococci in Bangladesh has been observed. However, the scenario remains incomplete, as few isolates (<1%) are available from pneumonia cases and most pneumococcal meningitis cases (>80%) are culture-negative. This study optimised a triplex PCR method to detect macrolide resistance genes (MRGs) (mefA and ermB) and cpsA from culture-negative pneumococcal cases to predict the prevalence and level of macrolide resistance...

BACKGROUND: The burden of maternal complications during antepartum and intrapartum periods is high and care seeking from a trained provider is low, particularly in low middle income countries of sub-Saharan Africa and South Asia. Identification of barriers to access to trained care and development of strategies to address them will contribute to improvements in maternal health. Using data from a community-based cohort of pregnant women, this study identified the prevalence of antepartum and intrapartum complications and determinants of care-seeking for these complications in rural Bangladesh...

BACKGROUND: Group B Streptococcus (GBS) is a predominant cause of early-onset neonatal sepsis (EOS) globally; however, the impact of this organism on the health of newborns in South Asia is debated, due in part to a paucity of community-based assessments. We estimated the prevalence and serotypes of GBS colonization of the umbilical cord stump, and the association of colonization with mortality in a population-based cohort of newborns in rural Sylhet District, Bangladesh. METHODS: Umbilical cord swabs were collected from 646 newborns up to three times within the first week after birth (ages <24 hours, ~3 days, ~6 days) and processed to identify GBS serotypes...

BACKGROUND: We conducted a social and verbal autopsy study to determine cultural-, social- and health system-related factors that were associated with the delay in formal care seeking in Sylhet district, Bangladesh. METHODS: Verbal and social autopsy interviews were conducted with mothers who experienced a neonatal death between October 2007 and May 2011. We fitted a semi-parametric regression model of the cumulative incidence of seeking formal care first, accounting for competing events of death or seeking informal care first...

BACKGROUND: Gestational age (GA) is frequently unknown or inaccurate in pregnancies in low-income countries. Early identification of preterm infants may help link them to potentially life-saving interventions. METHODS: We conducted a validation study in a community-based birth cohort in rural Bangladesh. GA was determined by pregnancy ultrasound (<20 weeks). Community health workers conducted home visits (<72 hours) to assess physical/neuromuscular signs and measure anthropometrics...

Antenatal care (ANC) remains an important contact point on the continuum of care for mothers and children in low- and middle-income countries. In Tanzania, the proportion of pregnant women completing at least four ANC visits (ANC-4) dropped from 70% to 43% between 1999 and 2010. To identify potential causes of the decline in the number of ANC visits, we conducted qualitative research at 18 health centres in Morogoro Region, exploring providers' communication about ANC visits and clients' and providers' perceptions of changes in ANC services and barriers to completing four visits...

The World Health Organization (WHO) currently coordinates rotavirus diarrhea and invasive bacterial disease (IBD) surveillance at 178 sentinel sites in 60 countries. However, only 78 sites participate in both surveillance systems using a common sentinel site. Here, we explored the feasibility of extending a WHO-IBD surveillance platform to generate data on the burden of rotaviral diarrhea and its epidemiological characteristics to prepare the countries to measure the impact of rotaviral vaccine. A six-month (July to December, 2012) surveillance, managed by IBD team, collected stool samples and clinical data from under-five children with acute watery diarrhea at an IBD sentinel site...

BACKGROUND: Insufficient knowledge of the etiology and risk factors for community-acquired neonatal infection in low-income countries is a barrier to designing appropriate intervention strategies for these settings to reduce the burden and treatment of young infant infection. To address these gaps, we are conducting the Aetiology of Neonatal Infection in South Asia (ANISA) study among young infants in Bangladesh, India and Pakistan. The objectives of ANISA are to establish a comprehensive surveillance system for registering newborns in study catchment areas and collecting data on bacterial and viral etiology and associated risk factors for infections among young infants aged 0-59 days...

BACKGROUND: Despite the high rate of deaths in young infants (0-59 days) attributable to infections in resource-poor countries, data on bacterial and viral etiologies of community-acquired infections in this age group are limited. These data are needed to develop appropriate preventive strategies and suitable antibiotic treatment regimens for reducing the number of young infant deaths from infections. The Aetiology of Neonatal Infection in South Asia (ANISA) study is designed to generate these critical data and is being implemented in Bangladesh, India and Pakistan...

The multisite community-based study, Aetiology of Neonatal Infection in South Asia (ANISA), uses blood culture as the gold standard for identifying the etiology of neonatal infection. Considering the importance of this age-old diagnostic tool and the risk of contamination, ANISA has employed rigorous measures to prevent contamination at all stages of blood collection, processing and culture. Because contamination may still occur, an independent expert group evaluates the routinely collected clinical and laboratory data to determine whether a blood culture isolate is a contaminant or a true pathogen...
