Science and society: promoting the learning of immunology in developing countries.

In 2005, the economic gap between developing and developed countries is bigger than ever, and this has consequences for public health. So, to sustain education and research in the most resource-constrained regions, it is necessary to promote local teaching of the immunology of infectious diseases. This Perspective article reviews the use and expected efficiency of current Internet-based tools for higher education in the biomedical sciences in developing countries. We also discuss other approaches to improve access to updated training in immunology for students in the poorest countries.

Patterns of infant weight gain in developing countries.

Data relating to weight of infants from 23 developing countries and two western industrialized populations taken from the literature were compared. Growth in the developing countries was extremely variable, but was poor compared to western standards such that by 12 months of age mean weight in all 23 populations was below the NCHS 50th percentile (P < 0.001) and in 11 populations mean weight was below the 10th percentile. Birth weight was not related to growth increment in the first 3 months. Multiple regression analysis showed birth weight and growth increments in the first four 3-month periods post-partum to be highly significantly related to weight at 12 months (P < 0.0001 in all cases). Growth increment in the first 3 months had the greatest effect out of these variables; the effect of the other four variables was similar. These patterns demonstrate the variable impact of environmental factors on growth in the first year of life.

Poison control centers in developing countries and Asia's need for toxicology education.

Poison control centers (PCCs) in developing countries have been set up in response to the challenge of decreasing mortality and morbidity from poisoning. The services range from poison information to actual clinical treatment mostly of acute cases. Lately, PCCs have expanded from their traditional role to one that actively engages in community health studies, toxicovigilance along with treatment of chronic poisoning. Recognizing that types of poisoning and specific needs may vary from country to country, toxicology education that addresses these unique regional issues has become more necessary. Toxicology education, both formal and informal, exists in various stages of development in Asia. Clearly, there are gaps that need to be addressed especially in areas where there are no poison centers or where strengthening is necessary. Collaboration between PCCs in developing countries can help augment available resources including human, analytical and technical expertise. The critical mass of trained toxicologists will fill in the demand for clinical and regulatory specialists and educators as well. This paper highlights the experiences and resources available to the Philippine and Malaysian poison centers and the strengths generated by networking and collaboration. The role of Asia Pacific Association of Medical Toxicology (APAMT) as the Science NGO representative to the Intergovernmental Forum on Chemical Safety (IFCS) forum standing committee in promoting chemical safety at the regional level will be discussed. The "Clearinghouse on the Sound Management of Chemicals", a platform for engaging multi-stakeholder and interdisciplinary partnerships, will be described as a possible model for capacity building to advance chemical safety through education and training not only in developing countries in Asia but globally as well.

Existing demand for birth spacing in developing countries: perspectives from household survey data.

OBJECTIVE: To identify the extent of demand for birth spacing, according to age and parity among married women of reproductive age (MWRA) in developing countries. METHODS: Secondary analysis of data from the Demographic and Health Surveys (DHS) using cross-tabulations. Data collected from nationally representative samples of MWRA in selected developing countries between 1990 and 2004. RESULTS: Demand for birth spacing is the most prevalent reason for an interest in family planning among married women aged 15-29 years in the majority of developing countries examined. In the 15-19-year age cohort, the demand for spacing is proportionally the most prevalent reason for a demand for family planning. A demand for spacing even exists among young, zero-parity married women in each country examined. Findings on the demand for spacing among zero-parity married women quantifies the expressed desire of some married women in developing countries to postpone a first birth or the timing of a first pregnancy. CONCLUSION: The substantial demand for birth spacing among young, low- and zero-parity women suggests that family planning programs in developing countries may need to reevaluate how accessible services are for this cohort of potential contraception users. Currently, many service-delivery protocols, counseling practices and service provider training may not fully address the needs of younger, low- or zero-parity clients.

[Trends and new factors affecting the brain drain from developing countries].

Current trends in brain-drain migration from developing to developed countries are analyzed. "Describing the growing specialisation of and rapid changes in the demand for qualified migrants in developed countries, this study shows that the brain drain phenomenon is increasingly fed by LDCs nationals migrating primarily for studies abroad. The resulting economic and social effects, both for sending and receiving countries, of the brain drains' modern patterns are analysed, as is the current action undertaken by various parties to eradicate this phenomenon."

[Evolution and new perspectives of health care financing in developing countries].

Over the last twenty five years, the perspective of health care financing has dramatically changed in developing countries. In this context, it is worth reviewing the literature and the experiences in order to understand the major shifts on this topic. During the sixties, health care policies focused on fighting major epidemics. Programs were dedicated to reduce the threat to population health. Financing related to the mobilization of resources for these programs and most of them were not managed within national administrations. The success of these policies was not sustainable. After Alma Ata, primary health care became a priority but it took some years before the management of the health care district was introduced as a major topic. In the eighties, with the district policy and the Bamako Initiative, the economic approach became a major part of all health care policies. At that time, most of health care financing was related to cost recovery strategies. All the attention was then drawn on how it worked: Fee policies, distribution of revenues, efficient use of resources and so on. In the second half of the nineties, cost recovery was relegated to the back scene, health care financing policy then becoming a major front scene matter. Two major reasons may explain this change in perspective: HIV which causes a major burden on the whole health system, and fighting poverty in relation with debts reduction. In most developing countries, with high HIV prevalence, access to care is no longer possible within the framework of the ongoing heath care financing scheme. Health plays a major role in poverty reduction strategies but health care officials must take into account every aspect of public financing. New facts also have to be taken into account: Decentralization/autonomy policies, the growing role of third party payment and the rising number of qualified health care professionals. All these facts, along with a broader emphasis given to the market, introduce a need for a better management of resources through financing mechanisms. Some major reports from WHO and the World Bank are the landmarks of the evolution on how to approach health care financing: The 1993 World Bank report on investing in health, the 2000 WHO report on health in the world and the WHO report on macroeconomics and health. In this early millenium, there is a general agreement on some major aspects of health care financing such as: Lack of resources for financing health care; cost recovery as a part of any sustainable health care system; health as a public good needing some extended subsidies; protecting people from the burden of disease as a part of financing schemes; equity in relation with the public private mix at the center of many debates; financing as a key mechanism for the regulation of the whole health care system and not only as a resource mobilization; HIV in bringing up new problems clearly shows how all these matters are related. Health care financing is at the heart of ongoing questions on health care reforms. Although developing countries have low insurance coverage and weak modern medical care, they share the same questions as developed countries: How to promote technical and allocative efficiency? What place for incentives? What role for the public sector? How can market and contracting bring results? What progress through stewardship and better governance?

Outcome in schizophrenia and related disorders compared between developing and developed countries. A recursive partitioning re-analysis of the WHO DOSMD data.

BACKGROUND: Data on the two-year pattern of course of illness have been collected in the WHO study of the Determinants of Outcomes of Severe Mental Disorder (DOSMD). These data are reanalysed using recursive partitioning, a method not yet applied to psychiatric data to test the hypothesis that subjects from participating centres in developing countries had better outcomes than those in developed countries. METHOD: Subjects were those from the DOSMD study for whom two-year follow-up data were available (n = 1056). The classification and regression trees recursive partitioning technique was used to examine the predictor variables associated with the outcome variable two year pattern of course. RESULTS: Pattern of course was best predicted by centre, but two developed centres (Prague and Nottingham) grouped with the developing country centres excluding Cali, having better outcomes than in the remaining developed country centres and Cali. Type of onset (insidious v. non-insidious) was the next strongest predictor, but its effect differed across these two centre groupings. Effects for some groups were modified by other predictor variables, including age, child and/or adolescent problems, and gender. CONCLUSIONS: The predominant predictor effects on two-year pattern of course continued to be centre and type of onset, but complex interactions between these variables and other predictor variables are seen in specific centre groupings not strictly defined by 'developing' and 'developed'.

Implementation of the semi-aerobic landfill system (Fukuoka method) in developing countries: a Malaysia cost analysis.

Most of the existing solid waste landfill sites in developing countries are practicing either open dumping or controlled dumping. Proper sanitary landfill concepts are not fully implemented due to technological and financial constraints. Implementation of a fully engineered sanitary landfill is necessary and a more economically feasible landfill design is crucial, particularly for developing countries. This study was carried out by focusing on the economics from the development of a new landfill site within a natural clay area with no cost of synthetic liner up to 10 years after its closure by using the Fukuoka method semi-aerobic landfill system. The findings of the study show that for the development of a 15-ha landfill site in Malaysia with an estimated volume of 2,000,000 m(3), the capital investment required was about US 1,312,895 dollars, or about US 0.84 dollars/tonne of waste. Assuming that the lifespan of the landfill is 20 years, the total cost of operation was about US 11,132,536 dollars or US 7.15 dollars/tonne of waste. The closure cost of the landfill was estimated to be US 1,385,526 dollars or US 0.89 dollars/tonne of waste. Therefore, the total cost required to dispose of a tonne of waste at the semi-aerobic landfill was estimated to be US 8.89 dollars. By considering an average tipping fee of about US 7.89 dollars/tonne of waste in Malaysia in the first year, and an annual increase of 3% to about US 13.84 dollars in year-20, the overall system recorded a positive revenue of US 1,734,749 dollars. This is important information for the effort of privatisation of landfill sites in Malaysia, as well as in other developing countries, in order to secure efficient and effective landfill development and management.

When do developing countries adopt managed care policies and technologies? Part II: Infrastructure, techniques, and reform strategies.

OBJECTIVES: To specify the essential infrastructure elements required to implement managed care techniques successfully in a developing country, once the necessary macroeconomic preconditions for managed care have been met. Also, to describe how managed care techniques can be integrated into health system reform strategies. STUDY DESIGN AND METHODS: Analysis of available developing country health system and healthcare spending data, review of the available literature, and authors' experience evaluating healthcare reform in developing countries. RESULTS: Successful managed care relationships among payers, providers, and patients rely on several essential infrastructure elements: enabling legislation; regulatory mechanisms to administratively correct health and insurance market failures; enforceable contracts; and formal groups or associations of providers. Once these infrastructure elements are in place, a developing country government can consider implementing 1 or more managed care techniques, including payment strategies, demand-side techniques, and utilization management. CONCLUSIONS: Governments in many developing countries can take deliberate steps to accelerate the evolution of certain macroeconomic preconditions--human capital and information systems--and essential infrastructure elements necessary to support managed care techniques. They may then choose to experiment carefully with implementing specific managed care techniques, with consideration given to how the managed care techniques can promote primary care.

HIV infection in children in developing countries.

Disease progression in children acquiring HIV infection vertically from their mothers is more rapid in developing countries compared with developed countries. The probability of death by 12 months in sub-Saharan Africa ranges from 0.23 to 0.35, and by 5 years is 0.57-0.68. Data from Europe in the era before highly active anti-retroviral therapy (HAART) yielded probabilities of 0.1 and 0.2, respectively. Confirming the diagnosis can be difficult in resource-limited settings. Existing clinical case definitions are useful epidemiologically, but of low positive-predictive value in individual children. Priorities for research into management issues include nutrition (infant feeding, vitamin A and micronutrient supplementation), prophylaxis against Pneumocystis carinii pneumonia (PCP), and bacterial infections, case management of persistent diarrhoea, diagnosis/prevention/management of tuberculosis in children and prevention of sexual transmission in adolescents.

Maternal immunisation in developing countries.

Maternal immunisation could help to prevent the 2-3 million neonatal and early infant deaths that occur in the developing world each year. Determining the causes of neonatal and early infant deaths in developing countries is difficult as most occur at home. However, it is likely that at least half are due to infections, several of which might be prevented by maternal immunisation. Even in poor countries with few health facilities, a high percentage of pregnant women attend an antenatal clinic at least once during pregnancy. Thus, an effective delivery system for maternal immunisation already exists and, because of the success of maternal tetanus immunisation, this approach to the prevention of serious illness or death in young infants is widely accepted by the general population. However, the high prevalence of HIV and malaria found in pregnant women in some parts of the developing world, especially sub-Saharan Africa, could have an effect on the efficacy of maternal immunisation as both of these infections adversely affect placental function. Nevertheless, the potential of maternal immunisation to prevent early infant deaths in developing countries needs to be fully explored. The incidence of pneumococcal infections is high in many developing countries and about 25% of these infections occur at an age before protection could be anticipated following vaccination with a pneumococcal conjugate vaccine in infancy. Thus, a strong case can be made for a trial of the effectiveness of maternal immunisation with a pneumococcal vaccine in preventing serious illness or death in young infants in developing countries.

Appropriate training in paediatric nephrology for developing countries: hypothesis and proposals.

Appropriate training in paediatric nephrology is a comprehensive approach designed to develop skills and capabilities to deal with the following basic components of medical care: (1) medical competence for clinical and research activities; (2) interpersonal relationships directed at maintaining patients' freedom and autonomy; and (3) adequate incorporation of technological, financial and managerial aspects of paediatric nephrology services. Inappropriate training causes frequent, dramatic and paradoxical negative feedback in developing countries: shortage of functioning medical equipment, skilled manpower and trained paediatric nephrologists co-exist with unused high-cost medical equipment and loss of skilled health care professionals. Appropriate training, tailored to the needs and resources of developing countries, could be an efficient way to develop high-quality paediatric nephrology care. Efficient training must develop self-reliant, self-sufficient and skilled health care professionals in the local economic, educational, technological and political context. Regional and international co-operation is essential to promote adequate training in paediatric nephrology. Developing countries lack an effective and accurate information communication network for selecting modern technology for paediatric nephrology. The development of this network through international co-operation, is an urgent requirement.

Ongoing research in occupational health and environmental epidemiology in developing countries.

Research in occupational health and environmental epidemiology can play an important role in furthering our understanding of occupational and environmental health problems. Research guides us in the recognition, management, and prevention of health problems. However, in developing countries, where rates of occupational and environmental illnesses and injuries are higher and where these problems are often more severe than in developed countries, research capabilities are less developed. In mid-1990, a project was undertaken to (a) document ongoing research in occupational health and environmental epidemiology in developing countries, (b) facilitate the exchange of information among researchers in this field, (c) stimulate research, and (d) avoid unnecessary duplication among researchers in this field. A questionnaire was mailed, the purpose of which was to learn the current status of research in developing countries and to develop a directory of such ongoing research. The questionnaire was sent to 1,528 individuals. Of the 500 research projects identified, 77% were investigating chemical hazards; 26%, physical hazards; 10%, biological hazards; and 10%, psychosocial hazards (some projects addressed multiple hazards). The chemical hazards studied most frequently were dusts, pesticides, and lead. The greatest number of research projects were identified in China, India, Brazil, Korea, and Thailand. Most projects were descriptive or cross-sectional epidemiologic studies or industrial hygiene or exposure-assessment studies. The World Health Organization has published a directory of the specific research projects that were identified in this survey.

[Problems in production, control and utilization of veterinary vaccines in the developing countries].

For a whole series of reasons, most of which are political, the developing countries are following a policy of national self-sufficiency in veterinary vaccines. They are faced with problems at various levels: (1) at the level of logistic distribution, the developing countries suffer from a shortage of trained personnel, frequently lacking in enthusiasm, an often chronic shortage of funds; poorly equipped premises; poor maintenance of sophisticated but indispensable equipment (e.g. freeze-driers); a lack of facilities for cold storage and of distribution channels; field personnel with limited experience; (2) at the level of production, they must contend with difficulties in obtaining supplies of flasks and glassware; irregular supplies of water and electricity; difficulties in obtaining susceptible animals for quality control. The developing countries have found basically pragmatic solutions to these problems, such as the strict separation of the sites, materials and personnel involved in routine diagnosis and those involved in production; temporary foreign technical assistance, with or without financial aid; the use of simple, unsophisticated techniques, which are known to be reliable, even if somewhat outdated; manufacturing in bulk in multiple-dose bottles; research into the thermostabilisation of vaccine strains and the development of thermoprotective diluents for freeze-drying and reconstitution; the extensive use of combined vaccines; the establishment of production and control standards under the auspices of the WHO/FAO/OIE. In spite of these obstacles, the cost price is particularly low (from 0.20 to 0.35 francs per dose), which compares favourably with that of foreign private industry.

[The present tuberculosis situation in developing countries].

Analysis of the tuberculosis situation and its dynamics in developing countries is given. The data on tuberculosis incidence in developing countries are inadequate and are probably by far higher than the figures reported. The rist of tuberculosis infection amounts up to 3% per year. In future it is supposed that the number of tuberculosis patients will rather increase than decrease. Effective tuberculosis control measures would be possible and are necessary. If nothing is done immediately, the cost of such measures will increase and human suffering will become more severe.

Papanicolaou screening in developing countries: an idea whose time has come.

Cervical cancer is the leading cause of cancer-related death among women in developing countries. Although progress is optional in all settings, Papanicolaou screening is feasible anywhere that cervical screening is appropriate and should be implemented without further delay in high-risk communities with access to curative treatment services. Successful prophylactic cervical cancer vaccines, prospects for which remain uncertain, will not eliminate requirements for cervical screening. The feasibility of human papillomavirus test analysis has not been demonstrated in low-resource developing country settings. Because past failures of cervical screening in developing countries are attributable to failures in programmatic quality rather than to technological limitations of the screening test, a shift in paradigmatic focus from technology toward quality is mandatory. Because visual screening techniques coupled with immediate ablative treatment are rendered obsolete by an embedded quality-control paradox, a moratorium should be placed on all such programs. Considerable opportunity costs, borne by the underserved, are associated with prioritizing research of novel interventions in developing countries when satisfactory interventions already exist.

A new approach for providing occupational health services in developing countries.

A comprehensive approach to the health problems of workers and the gainfully employed should be adopted when occupational health services are planned in developing countries. The system developed in industrialized countries cannot be applied to new industrializing countries. The definition of what constitutes a developing country is not yet agreed upon. They share many of the criteria which create a vicious cycle of poverty and disease. This cycle can only be broken by industrialization and economic progress. The maintenance of health in industrial communities in the developing countries entails the treatment and prevention of epidemic and endemic communicable diseases, the prevention of occupational injuries and diseases, the planning and organization of medical care, training, the introduction and enforcement of standards of health, and safety and medical care in industry. To achieve this a new approach is advocated. The total health services are visualized as a spectrum, while occupational health services are used as a springboard and a point of entry. The health personnel who provide services to workers in factories, agricultural projects, and mines can carry out a comprehensive preventive program for the workers and their families.
