Background: Few Asian countries have introduced Haemophilus influenzae type b (Hib) conjugate vaccine because of its cost and uncertainty regarding disease burden. Methods: To estimate the effectiveness of Hib conjugate vaccine in preventing pneumonia and meningitis in children age <2 years, an incident case–control study was conducted in a birth cohort of about 68,000 infants in Dhaka city, Bangladesh. DPT vaccine was systematically replaced by a combined Hib-DPT vaccine in selected immunization centers of the study area. Four matched community- and 2 hospital-controls were randomly selected for each confirmed case of pneumonia and meningitis from the study area. Results: About 35% of the infants received each of the 3 doses of Hib-DPT vaccine. There were 2679 children who had a chest roentgenogram. For 475 children, a radiologist and a pediatrician independently identified substantial alveolar consolidation. Following at least 2 doses of Hib vaccine, the preventable fractions [95% confidence intervals (CI)] using community and hospital controls were 17% (−10% to 38%) and 35% (13% to 52%) respectively. Of these 475 cases, 2 radiologists with the World Health Organization concurred with the findings for 343 patients, yielding preventable fractions of 34% (6% to 53%) and 44% (20% to 61%). Fifteen confirmed Hib meningitis cases were identified; the preventable fractions (95% CI) using community and hospital controls, respectively, were 89% (28% to 100%) and 93% (53% to 100%). Conclusions: The study documented that significant fractions of pneumonia and meningitis in Bangladeshi children age <2 years can be prevented by the Hib conjugate vaccine.
Background Antibiotic treatment for pneumonia as measured by Demographic and Health Surveys (DHS) and Multiple Indicator Cluster Surveys (MICS) is a key indicator for tracking progress in achieving Millennium Development Goal 4. Concerns about the validity of this indicator led us to perform an evaluation in urban and rural settings in Pakistan and Bangladesh. Methods and Findings Caregivers of 950 children under 5 y with pneumonia and 980 with "no pneumonia" were identified in urban and rural settings and allocated for DHS/MICS questions 2 or 4 wk later. Study physicians assigned a diagnosis of pneumonia as reference standard; the predictive ability of DHS/MICS questions and additional measurement tools to identify pneumonia versus non-pneumonia cases was evaluated. Results at both sites showed suboptimal discriminative power, with no difference between 2- or 4-wk recall. Individual patterns of sensitivity and specificity varied substantially across study sites (sensitivity 66.9% and 45.5%, and specificity 68.8% and 69.5%, for DHS in Pakistan and Bangladesh, respectively). Prescribed antibiotics for pneumonia were correctly recalled by about two-thirds of caregivers using DHS questions, increasing to 72% and 82% in Pakistan and Bangladesh, respectively, using a drug chart and detailed enquiry. Conclusions Monitoring antibiotic treatment of pneumonia is essential for national and global programs. Current (DHS/MICS questions) and proposed new (video and pneumonia score) methods of identifying pneumonia based on maternal recall discriminate poorly between pneumonia and children with cough. Furthermore, these methods have a low yield to identify children who have true pneumonia. Reported antibiotic treatment rates among these children are therefore not a valid proxy indicator of pneumonia treatment rates. These results have important implications for program monitoring and suggest that data in its current format from DHS/MICS surveys should not be used for the purpose of monitoring antibiotic treatment rates in children with pneumonia at the present time.

Sepsis is dysregulated systemic inflammatory response which can lead to tissue damage, organ failure, and death. With an estimated 30 million cases per year, it is a global public health concern. Severe infections leading to sepsis account for more than half of all under five deaths and around one quarter of all neonatal deaths annually. Most of these deaths occur in low and middle income countries and could be averted by rapid assessment and appropriate treatment. Evidence suggests that service provision and quality of care pertaining to sepsis management in resource poor settings can be improved significantly with minimum resource allocation and investments. Cognizant of the stark realities, a project titled 'Interrupting Pathways to Sepsis Initiative' (IPSI) introduced a package of interventions for improving quality of care pertaining to sepsis management at 2 sub-district level public hospitals in rural Bangladesh. We present here the quality improvement process and achievements regarding some fundamental steps of sepsis management which include rapid identification and admission, followed by assessment for hypoxemia, hypoglycaemia and hypothermia, immediate resuscitation when required and early administration of parenteral broad spectrum antibiotics.Key components of the intervention package include identification of structural and functional gaps through a baseline environmental scan, capacity development on protocolized management through training and supportive supervision by onsite 'Program Coaches', facilitating triage and rapid transfer of patients through 'Welcoming Persons' and enabling rapid treatment through 'Task Shifting' from on-call physicians to on-duty paramedics in the emergency department and on-call physicians to on-duty nurses in the inpatient department.From August, 2013 to March, 2015, 1,262 under-5 children were identified as syndromic sepsis in the emergency departments; of which 82% were admitted. More neonates (30%) were referred to higher level facilities than post-neonates (6%) (p<0.05). Immediately after admission, around 99% were assessed for hypoxemia, hypoglycaemia and hypothermia. Around 21% were hypoxemic (neonate-37%, post-neonate-18%, p<0.05), among which 94% received immediate oxygenation. Vascular access was established in 78% cases and 85% received recommended broad spectrum antibiotics parenterally within 1 hour of admission. There was significant improvement in the rate of establishing vascular access and choice of recommended first line parenteral antibiotic over time. After arrival in the emergency department, the median time taken for identification of syndromic sepsis and completion of admission procedure was 6 minutes. The median time taken for completion of assessment for complications was 15 minutes and administration of first dose of broad spectrum antibiotics was 35 minutes. There were only 3 inpatient deaths during the reporting period.Needs based health systems strengthening, supportive-supervision and task shifting can improve the quality and timeliness of in-patient management of syndromic sepsis in resource limited settings.
Abstract Background Epidemiological studies on the prevalence and management of chronic low back pain (CLBP), osteoarthritis (OA), and diabetic peripheral neuropathy (DPN) are limited in Egypt. This review aimed to map and identify data gaps in the patient journey touchpoints for CLBP, OA, and DPN. Main body of the abstract An evidence-based mapping approach using MEDLINE, Embase, and Biosis databases were used to identify records between January 2010 and December 2019. Quantitative data synthesis was performed using simple mean or weighted mean, whereas qualitative information was synthesized using a narrative summary. For CLBP, of the 79 records retrieved, 11 were eligible for final analysis (7 CLBP and 4 OA records), and for DPN, of 42 records identified, 13 studies were eligible. For CLBP, data available for prevalence, awareness, and treatment were 34.3%, 39.5%, and 70.0%, respectively. The prevalence of OA was 43.0%. The majority (98.6%) of patients with OA adhered to the treatment, and in 96.2% of the patients’ symptoms were controlled. The prevalence of DPN was estimated to be 42.7%, synthesized evidence indicated that 14.1% of patients were aware of DPN and 22.7% underwent screening. Conclusion As the existing literature is limited, further evidence-based studies are required to accurately understand the complexity of patient journey touchpoints in Egypt. Although the studies on musculoskeletal chronic pain syndrome are limited, the high prevalence of chronic low back pain, osteoarthritis and peripheral neuropathy should urge the health care system to organize the research groups and health care facilities to focus on these disorders and to consider them in the global health care plans.
To identify main groups of stakeholders in the process of health research priority setting and propose strategies for addressing their systems of values.In three separate exercises that took place between March and June 2006 we interviewed three different groups of stakeholders: 1) members of the global research priority setting network; 2) a diverse group of national-level stakeholders from South Africa; and 3) participants at the conference related to international child health held in Washington, DC, USA. Each of the groups was administered different version of the questionnaire in which they were asked to set weights to criteria (and also minimum required thresholds, where applicable) that were a priori defined as relevant to health research priority setting by the consultants of the Child Health and Nutrition Research initiative (CHNRI).At the global level, the wide and diverse group of respondents placed the greatest importance (weight) to the criterion of maximum potential for disease burden reduction, while the most stringent threshold was placed on the criterion of answerability in an ethical way. Among the stakeholders' representatives attending the international conference, the criterion of deliverability, answerability, and sustainability of health research results was proposed as the most important one. At the national level in South Africa, the greatest weight was placed on the criterion addressing the predicted impact on equity of the proposed health research.Involving a large group of stakeholders when setting priorities in health research investments is important because the criteria of relevance to scientists and technical experts, whose knowledge and technical expertise is usually central to the process, may not be appropriate to specific contexts and in accordance with the views and values of those who invest in health research, those who benefit from it, or wider society as a whole.
Elevated exposure to the essential element manganese (Mn) can be toxic. Manganese concentrations in ground water vary considerably, and reported associations between Mn and early-life mortality and impaired development have raised concern. We assessed the effects of drinking water Mn exposure during pregnancy upon fetal and infant survival.In this population-based cohort study, we identified the outcomes of pregnancies registered between February 2002 and April 2003 in Matlab, Bangladesh. Using inductively coupled plasma mass spectrometry, we measured the concentrations of Mn and other elements in the pregnant women's drinking water.A total of 1,875 women were included in the analysis of spontaneous abortions (n=158) and 1,887 women in the perinatal mortality analysis (n=70). Water Mn ranged from 3.0-6,550 µg/L (median=217 µg/L). The adjusted odds ratio (OR) for spontaneous abortion was 0.65 (95% CI 0.43-0.99) in the highest water Mn tertile (median=1,292 µg/L) as compared to the lowest tertile (median=56 µg/L). The corresponding OR for perinatal mortality was 0.69 (95% CI 0.28-1.71), which increased to 0.78 (95% CI 0.29-2.08) after adjustment for BMI and place of delivery (home/health facility; n=1,648).Elevated water Mn concentrations during pregnancy appear protective for the fetus, particularly in undernourished women. This effect may be due to the element's role in antioxidant defense.
Background: In Bangladesh, neonatal sepsis is the cause of 24% of neonatal deaths, over 65% of which occur in the early-newborn stage (0-7 days). Only 50% of women initiate breastfeeding their newborn within 1 hour of birth. The mechanism by which early initiation of breastfeeding reduces neonatal deaths is unclear, although the most likely pathway is by decreasing neonatal sepsis. This study explores the effect of breastfeeding initiation time on early-onset newborn sepsis. Methods: We used data from a large community-based trial in Bangladesh where we enrolled pregnant women from 2013-2015 covering 30,646 newborns. Syndromic sepsis was defined using newborn danger signs reported by “The Young-Infants Clinical Science Study Group.” We categorized the timing of initiation of breastfeeding as within 1 hour, 1-24 hours, 24-48 hours, ≥48 hours of birth, and never breastfed. The analysis includes descriptive statistics, risk attribution, and binomial logistic-regression while adjusting for clustering effects of the trial design, and maternal and infant characteristics.Findings: 29,873 live-births had information on breastfeeding initiation among whom 4,437 (14·8%) neonates had signs of sepsis by the 7th day after birth. Two-thirds of the newborns [66·7%, (n=19,914)] had breastfeeding initiated within 1hr of birth. The mean time to initiation was 3·8 hours (±16·6 hours), and by the end of 48 hours, all but 5·7% of neonates were breastfed. The proportion of children with syndromic sepsis increased as the initiation of breastfeeding was delayed from 1 hour (12·0%), 24 hours (15·7%), 48 hours (27·7%), to more than 48 hours (36·7%) after birth. It would be possible to avert 15·9%, 10·6% and 8·5% of early-onset sepsis cases if all children initiated breastfeeding within 1, 24 or 48 hours of birth respectively. The odds of having sepsis is significantly higher among late initiators. Children who initiated after 48 hours (OR 4·13, 95% CI 3·48-4·89) and children who never initiated (OR 4·77, 95% CI 3·52-6·47) had the highest odds of having signs of sepsis. Interpretation: Our findings indicate that the timing of initiation of breastfeeding, especially within the first hour of birth, has a significant protective effect on early-onset sepsis among newborns. Community-based interventions to promote early initiation of breastfeeding should be tailored to suit the needs of populations where newborns are delivered at home by unskilled attendants, the rate of LBW is high, and post-natal care is limited.Clinical Trial Number: Australia New Zealand Clinical Trials Registry (ANZCTR): The registration ID is ACTRN12612000588897.Funding Statement: National Health and Medical Research Council [NHMRC] (of Australia) funded this study (#1026864).
