RESUMO
Tuberculosis (TB) and non-communicable diseases (NCD) share predisposing risk factors. TB-associated NCD might cluster within households affected with TB requiring shared prevention and care strategies. We conducted an individual participant data meta-analysis of national TB prevalence surveys to determine whether NCD cluster in members of households with TB. We identified eligible surveys that reported at least one NCD or NCD risk factor through the archive maintained by the World Health Organization and searching in Medline and Embase from 1 January 2000 to 10 August 2021, which was updated on 23 March 2023. We compared the prevalence of NCD and their risk factors between people who do not have TB living in households with at least one person with TB (members of households with TB), and members of households without TB. We included 16 surveys (n = 740,815) from Asia and Africa. In a multivariable model adjusted for age and gender, the odds of smoking was higher among members of households with TB (adjusted odds ratio (aOR) 1.23; 95% CI: 1.11-1.38), compared with members of households without TB. The analysis did not find a significant difference in the prevalence of alcohol drinking, diabetes, hypertension, or BMI between members of households with and without TB. Studies evaluating household-wide interventions for smoking to reduce its dual impact on TB and NCD may be warranted. Systematically screening for NCD using objective diagnostic methods is needed to understand the actual burden of NCD and inform comprehensive interventions.
RESUMO
Background: Non-communicable diseases (NCDs) and NCD risk factors, such as smoking, increase the risk for tuberculosis (TB). Data are scarce on the risk of prevalent TB associated with these factors in the context of population-wide systematic screening and on the association between NCDs and NCD risk factors with different manifestations of TB, where â¼50% being asymptomatic but bacteriologically positive (subclinical). We did an individual participant data (IPD) meta-analysis of national and sub-national TB prevalence surveys to synthesise the evidence on the risk of symptomatic and subclinical TB in people with NCDs or risk factors, which could help countries to plan screening activities. Methods: In this systematic review and IPD meta-analysis, we identified eligible prevalence surveys in low-income and middle-income countries that reported at least one NCD (e.g., diabetes) or NCD risk factor (e.g., smoking, alcohol use) through the archive maintained by the World Health Organization and by searching in Medline and Embase from January 1, 2000 to August 10, 2021. The search was updated on March 23, 2023. We performed a one-stage meta-analysis using multivariable multinomial models. We estimated the proportion of and the odds ratio for subclinical and symptomatic TB compared to people without TB for current smoking, alcohol use, and self-reported diabetes, adjusted for age and gender. Subclinical TB was defined as microbiologically confirmed TB without symptoms of current cough, fever, night sweats, or weight loss and symptomatic TB with at least one of these symptoms. We assessed heterogeneity using forest plots and I2 statistic. Missing variables were imputed through multi-level multiple imputation. This study is registered with PROSPERO (CRD42021272679). Findings: We obtained IPD from 16 national surveys out of 21 national and five sub-national surveys identified (five in Asia and 11 in Africa, N = 740,815). Across surveys, 15.1%-56.7% of TB were subclinical (median: 38.1%). In the multivariable model, current smoking was associated with both subclinical (OR 1.67, 95% CI 1.27-2.40) and symptomatic TB (OR 1.49, 95% CI 1.34-1.66). Self-reported diabetes was associated with symptomatic TB (OR 1.67, 95% CI 1.17-2.40) but not with subclinical TB (OR 0.92, 95% CI 0.55-1.55). For alcohol drinking ≥ twice per week vs no alcohol drinking, the estimates were imprecise (OR 1.59, 95% CI 0.70-3.62) for subclinical TB and OR 1.43, 95% CI 0.59-3.46 for symptomatic TB). For the association between current smoking and symptomatic TB, I2 was high (76.5% (95% CI 62.0-85.4), while the direction of the point estimates was consistent except for three surveys with wide CIs. Interpretation: Our findings suggest that current smokers are more likely to have both symptomatic and subclinical TB. These individuals can, therefore, be prioritised for intensified screening, such as the use of chest X-ray in the context of community-based screening. People with self-reported diabetes are also more likely to have symptomatic TB, but the association is unclear for subclinical TB. Funding: None.
RESUMO
BACKGROUND: To achieve the United Nations Millennium Development Goals, particularly reduction in child mortality (Millennium Development Goal 4), effective interventions to address severe and moderate acute malnutrition (SAM and MAM) among children under 5 years of age must be implemented and brought to scale alongside preventive measures. Bangladesh has an estimated 600,000 children with SAM, for a prevalence of 4%, while 1.8 million children suffer from MAM. OBJECTIVE: To assess the feasibility and constraints of community-based management of acute malnutrition (CMAM), a relatively new approach, in managing SAM and MAM among children in Bangladesh. METHODS: The methodology involved desk reviews of documents by searching through PubMed and other databases for published literature on CMAM in Bangladesh. We also did a hand search of policy and program documents, including the draft National Nutrition Policy 2013; the Health, Nutrition, Population Sector Development Program document of the Ministry of Health and Family Welfare, Government of Bangladesh; the Sixth Five Year Plan; and the Operational Plans of the National Nutrition Services of Bangladesh. RESULTS: . The conventional approach in Bangladesh has been to treat children suffering from SAM and associated complications in hospital settings. There is no program to take care of children with MAM. There is a dearth of local evidence to operationalize and implement CMAM in the context of Bangladesh. This paper summarizes the scientific literature and rationale for the implementation of CMAM in Bangladesh. It also provides recommendations to improve health strategies related to CMAM, discusses diets being developed that may result in better implementation of CMAM, and offers recommendations for areas of additional necessary research. CONCLUSIONS: A recommended approach for Bangladesh on the management of acute malnutrition would be to integrate CMAM into the rollout of the National Nutrition Services so that screening, identification, referral, and treatment of acutely malnourished children could be effectively managed within the community-based health service delivery system. Given that the vast majority of children are suffering from MAM and could be treated with locally developed food supplements, a significant emphasis of the CMAM approach in Bangladesh should be to screen and treat MAM. Over time, this would also result in fewer SAM cases. However, even with this approach, there would still be a small number of children who have SAM and who ideally should be treated with specialized therapeutic foods. While the Government of Bangladesh is awaiting full-scale production of a local ready-to-use therapeutic food (RUTF), an interim strategy is needed to effectively treat these severely wasted children on an outpatient basis.

To explore Bangladesh's ability to detect novel influenza, we examined a series of laboratory-confirmed pandemic (H1N1) 2009 cases. During June-July 2009, event-based surveillance identified 30 case-patients (57% travelers); starting July 29, sentinel sites identified 252 case-patients (1% travelers). Surveillance facilitated response weeks before the spread of pandemic (H1N1) 2009 infection to the general population.
