A number of studies have estimated the income elasticity of health care expenditure to identify whether health care is a necessary or luxury product. However, the issue has received less attention in developing countries, especially in Asian economies. The current study for the first time has used the panel data covering 36 Asian countries for the period 1995–2013 for revealing the nature of health care as a product. Along with conventional econometric techniques we have addressed the issue of cross section dependence and used Westerlund (2007) panel cointegration test which is robust against cross section dependence and heterogeneity for detecting the presence of panel cointegration. By applying Fully Modified OLS (FMOLS) and Dynamic OLS (DOLS) it was found that the long run elasticity of Health Care Expenditure (HCE) with Gross Domestic Product (GDP) is less than unit implying that the health care can be regarded as necessary in nature for these countries.

SummaryThe efficacy of single-dose combination drug therapy with diethylcarbamazine (DEC) plus albendazole (ALB), and single-drug therapy with DEC alone against geohelminths was compared as part of a mass drug administration (MDA) for elimination of filariasis. This study was conducted in two blocks of Villupuram District of Tamil Nadu State, India, covering a population of 321 000 including about 100 000 children 1-15 years of age. Prevalence and intensity of geohelminth infection were determined by the Kato-Katz technique immediately before and 3 weeks after the MDA. A pre-treatment cross-sectional survey was undertaken in 18 statistically selected villages out of 204 villages, including 646 school children. About 60% were infected with one or more geohelminths. The overall prevalence rates were 53.9%, 12.4% and 5.7% for Ascaris lumbricoides, hookworms and Trichuris trichiura, respectively. Combination therapy (DEC + ALB) produced a cure rate of 74.3% and an egg reduction rate of 97.3% for geohelminths, which were higher than the corresponding rates (30.4% and 79.0%) observed in the single drug therapy arm with DEC alone. The odds of cure with combination therapy were significantly higher for roundworm (5.3 times) and hookworms (3.5 times), then odds of cure with DEC alone. Both therapies were equally effective against trichuriasis, recording cure rates >77% and egg reduction rates >83%. In combination therapy, 53.5% of the children noticed expulsion of worms after MDA, while in single drug therapy only 20.9% did. Our study indicated that MDA of combination therapy was operationally feasible at the community level, and it may secure higher community compliance because of its perceived benefits and enhanced efficacy against geohelminths than single-drug therapy.

This study was conducted to evaluate the zoonotic gastrointestinal parasitic infections in cattle at Sirajganj district of Bangladesh during the period from February, 2016 to November, 2016 by coproscopy examination. A total of 150 fecal samples of cattle were collected from the study areas, which examined and found 41 (27.33%) were positive for gastrointestinal parasitic infections that has zoonotic importance. The prevalence of parasitic infection was significantly higher in female (33.7%) than in males (19. 4%). The prevalence of parasite was recorded higher in cross breed than in indigenous cattle which are statistically significant (p≤0.05). In case of age groups, the highest rate of infection was observed in adult of >1 years (28.5%) and the lowest in calves aged ≤1 year (25.4%). Moreover, the prevalence of gastrointestinal parasites were higher in poor body conditioned cattle (36.3%) than that of malnourished (34%) and healthy cattle (22.4%). In case of management system, the prevalence of parasitic infections was higher in cattle reared in free range (40.0%) than cattle reared in semi-intensive (28.5%) and intensive system (25.5%). Furthermore, parasitic infections were higher in summer (36.5%) followed by winter season (25.5%) and rainy season (15.7%). A significant correlation (P=0.00) has been found between diarrheic non-diarrhea cattle. Finally, prevalence was significantly (P=0.02) higher in cattle with no previous history of anthelmintic use. From this study, it is concluded that gastrointestinal parasitic infection is a major threat to cattle health and production at Sirajganj district irrespective of age, sex, management system, breed, season, diarrheic and anthelmintic usage.

Background Antibiotic resistance is a global threat to human health, and inappropriate use of antibiotics in humans and animals is widely considered to be a key driver of antibiotic resistant infections. Antibiotic use in humans and animals is growing rapidly in low- and, particularly, middle-income countries. However, there is little detailed understanding about practices related to the use of antibiotics in humans and animals within community settings in such countries. Here we aimed to understand the antibiotic practices of rural households across Cumilla district, Bangladesh, in relation to household members and their domestic animals. Methods In 2018 we conducted a cross-sectional survey using representative cluster sampling methods. We collected self-reported information from 682 female and 620 male household heads, with women also asked about their children’s antibiotic practices. Results Only 48% (95% CI: 40, 56%) of women and men had heard of antibiotics, and among those women and men who were aware of antibiotics and the children of those women 70% (95% CI: 64, 76%) reported having previously taken antibiotics, while among these individuals who reported previously taking antibiotics 21% (95% CI: 18, 25%) said they had done so most recently within the last month. Risky/inappropriate antibiotic practices in humans and animals were often reported. For example, among women and men who were aware of antibiotics and the children of those women 52% (95% CI: 40, 63%) reported previously taking antibiotics for a “cough/cold”, despite antibiotics being typically inappropriate for use against viral upper respiratory tract infections. Among poultry-owning respondents who were aware of antibiotics 11% (95% CI: 8, 15%) reported previously giving healthy poultry antibiotics, mainly for growth/prophylaxis, while among cattle-owning respondents who were aware of antibiotics and reported previously giving their cattle feed 20% (95% CI: 9, 37%) said the feed had contained antibiotics at least sometimes. Conclusions Our results highlight the need for context-adapted interventions at both the community level and the health systems level to reduce inappropriate antibiotic use among humans and domestic animals in rural Bangladesh. Successfully reducing inappropriate use of antibiotics among humans and animals is a required and critical step in tackling antimicrobial resistance.

The current Indian campaign for the elimination of lymphatic filariasis is largely based on mass drug administration (MDA). As part of this campaign, villagers in the Tirukoilur and Mugaiyur 'blocks' (i.e. revenue units) of Villupuram district, in Tamil Nadu, India, were treated with diethylcarbamazine (DEC), either alone (Mugaiyur) or with albendazole (Tirukoilur), in March 2001. The efficacy of treatment, in each of the two treatment arms, was evaluated by determining the percentages of the subjects who were carrying antigen from adult Wuchereria bancrofti before, 6 months and 12 months after the MDA. In a cross-sectional survey at each time-point, commercial, immunochromatographic tests were used to check 1000-1200, randomly selected, young residents (aged 2-25 years) of 18 index villages for the antigen; at least 300 villagers aged 2-9 years and at least 170 aged 10-25 years from each treatment arm were screened in each survey. Before the MDA, 12.7% of the subjects aged 2-9 years and 23.6% of those aged 10-25 years were found to be positive for the filarial antigen. Although only about 50% of villagers aged 2-9 years were successfully treated, MDA (with DEC alone or DEC plus albendazole) led to a significant (28.7%) reduction in the prevalence of antigenaemia in this age-group 6 months later (P<0.05). Although, the prevalences of antigenaemia among those aged 2-9 years were higher 12 months post-treatment than 6 months post-treatment, they were still lower (by 16%-23%) than those observed pre-treatment. The addition of albendazole to the DEC treatment appeared to offer no additional benefit in terms of the prevalence of antigenaemia in children aged <10 years; in fact, the use of DEC alone produced a slightly greater reduction in the prevalence of antigenaemia than the use of both DEC and albendazole. In the block given MDA based on both DEC and albendazole, the prevalences of antigenaemia among the villagers aged 10-25 years were 19.4% and 16.6% lower 6 and 12 months post-treatment, respectively, than observed pre-treatment. Curiously, in the block given DEC alone, the prevalences in this age-group were higher at both post-treatment follow-ups (by 17.4% at 6 months and 35.1% at 12 months) than observed pre-treatment. In concurrent experimental studies, high drug compliance (90%) among young children (aged 2-5 years) led to a pronounced (62.6%) reduction in the prevalence of antigenaemia after one MDA. In follow-up studies of those found antigen-positive, 40% of those aged 2-9 years but only 23% of those aged 10-25 years cleared their antigenaemias after three (annual) MDA. To maximize the benefits of MDA, greater efforts should be made to increase treatment coverage among young children.

IntroductionDespite an extensive evidence base on the diverse economic, environmental and social benefits of tobacco control, difficulties in establishing coordinated national approaches remain a defining challenge for Framework Convention on Tobacco Control (FCTC) implementation. Minimising tobacco industry interference is seen as key to effective coordination, and this paper analyses implementation of Article 5.3 guidelines, exploring implications for whole-of-government approaches to tobacco control in Bangladesh, Ethiopia, India and Uganda.MethodsBased on 131 semistructured interviews with government officials and other key stakeholders, we explore barriers and facilitators for promoting: (1) horizontal coordination across health and other policy spheres, and (2) vertical coordination across national and subnational governments on Article 5.3 implementation.ResultsOur analysis identifies common barriers to coordination across diverse geographical contexts and varying approaches to implementation. They highlight broadly shared experiences of limited understanding and engagement beyond health agencies; restricted responsibility and uncertainty amid conflicting mandates; tensions with wider governance practices and norms; limited capacity and authority of coordination mechanisms; and obstacles to vertical coordination across local, state and national governments. Interview data also indicate important opportunities to advance coordination across sectors and government levels, with Article 5.3 measures capable of informing changes in practices, building support in other sectors, allowing for ‘bottom-up’ innovation and being shaped by engagement with civil society.ConclusionSupporting effective implementation of Article 5.3 is key to advancing multisectoral approaches to FCTC implementation and tobacco control’s contributions to global health and sustainable development.

IntroductionBangladesh has not yet adopted measures to implement Article 5.3 of the WHO Framework Convention on Tobacco Control. The National Tobacco Control Cell (NTCC) has drafted a guideline for implementation, but progress has stalled amid high levels of tobacco industry interference in public policy. This paper examines the barriers to minimising industry interference in a context of close relationships between government officials and tobacco companies.MethodsIn-depth interviews were conducted with government officials, representatives from civil society, think tank and media organisations, and academic researchers. The data were analysed using a ‘3 Is’ framework developed within the political sciences, emphasising the interactive role of ideas, interests and institutions in policy change.ResultsThe findings indicate that policy ideas about protecting public health policy making from tobacco industry interests are largely restricted to the Ministry of Health and Family Welfare, and the NTCC specifically. Both individual and institutional conflicts of interest emerge as key barriers to progress to minimising industry interference and for tobacco control governance more broadly. The data also suggest that development of an Article 5.3 guideline has been shaped by the perceived interests of political actors and institutions, and the institutional position of the NTCC, constrained by limits on its resources, authority and isolation from other ministries.ConclusionNTCC’s initiatives towards implementing Article 5.3 constitute an important opportunity to address conflicts of interest that restrict tobacco control in Bangladesh. Progress in minimising industry interference is essential to realising the commitment to being smoke free by 2040.

BackgroundConcerns about the magnitude of illicit cigarette trade have prevented the Government of Pakistan from increasing tobacco taxes. We estimated the proportion of illicit cigarettes sold in Pakistani cities. Moreover, we compared two methods for collecting cigarette packs and investigated if the illicit cigarette trade equates to tax evasion.MethodWe analysed cigarette packs collected from 10 cities of Pakistan using two methods: consumer survey based on a two-stage random sampling strategy to recruit adult smokers and photograph their cigarette packs and waste recycle store survey to purchase used cigarette packs. Cigarettes were considered illicit if any one of the following was absent from their packs: text and pictorial health warning, underage sale prohibition warning, retail price and manufacturer’s name. From the consumer survey, we also estimated the proportion of smokers who purchased loose cigarettes (illegal) and packs below the minimum retail price. Taxation officers (n=4) were consulted to assess their level of confidence in judging tax evasion using the above criteria.ResultsOut of 2416 cigarette packs in the consumer survey, 454 (17.8%; 95% CI 15.4% to 20.2%) were illicit. Similarly, out of 6213 packs from waste recycle shops, 1046 (16.8%; 95% CI 15.9% to 17.7%) were illicit; the difference was not statistically significant (p=0.473). Among consumers, 29.5% bought loose cigarettes and 13.8% paid less than the minimum retail price. The taxation officers considered the manufacturer’s name and retail price on cigarette packs as the most relevant criteria to detect tax evasion.ConclusionsOne in six cigarette packs consumed in Pakistan could be illicit. These figures are far less than those propagated by the tobacco industry. Collecting packs from waste recycle stores is an efficient and valid method to estimate illicit cigarette trade.
