This report provides policy recommendations to help deliver safer and cheaper medical products to people suffering from neglected diseases in developing countries, where they are needed the most.
Although more drugs and vaccines are reaching late-stage clinical development, says the report, they are held back by a lack of funding to support clinical trials, as well as clinical research and regulatory capacity in settings where neglected diseases are endemic. This undermines safety and the validity of clinical data.
The report recommends a two-pronged approach to improving the quality and regulation of clinical trials in the developing world: establishing regional regulatory pathways for the oversight of clinical trials, and building quality and cost-efficiency into trial design and implementation. It also recommends practical steps that can be taken by donors, drug and vaccine developers, and regulatory authorities to begin implementing the changes.

This peer-reviewed report, from the UK Department for International Development (DFID), summarises current evidence on malaria, covering topics that range from epidemiology to public health interventions, disease management and elimination. It focuses on areas where policy or practical decisions have to be made, mainly by DFID and its development partners.
The paper is divided into sections that provide an overview of issues such as determinants of infection, high-risk groups, artemisinin and insecticide resistance, and interventions such as vector control. These correspond to areas relevant to decision making, with the report being a 'portal' to more detailed information rather than a definitive document. Because many of the issues addressed are context-specific, the paper should be read in conjunction with country profiles published by DFID as well as country-specific data available in the World Malaria Report.

This report, from medical aid organisation Médecins Sans Frontières, explores the impact of and lessons learned from the use of antiretroviral treatment (ART) for HIV/AIDS since 2000, when it began providing this to people in need of urgent treatment. It presents results of a survey conducted in 16 countries with different prevalence levels of the disease, which together account for 52.5 per cent of the global HIV/AIDS burden, and outlines the progress, strengths and weaknesses of the international response to the disease.
The report provides an overview of key treatment strategies to improve care and reduce its cost for patients and health systems; discusses the impact of decreased donor funding; and suggests policies that can help lower drug costs, for example, or foster innovations for more effective and affordable treatment. Most HIV-prevalent countries still lack the capacity to treat more than 50 per cent of their population in need of ART, or to provide ART in more than 50 per cent of existing facilities — underlining the need for more domestic and external resources.

This report examines the threat posed by non-communicable diseases in low- and middle-income countries, which carry nearly 80 per cent of the world's burden of cardiovascular disease; diabetes; cancer; obesity; and chronic respiratory disease. It includes tables and maps of global, regional and country-specific trends including estimated mortality rates. The data are also used to predict future trends and assess factors contributing to non-communicable disease.
Drawing on what developed countries have learned about these diseases, the report outlines options for tackling them, such as early detection and treatment. To encourage immediate action, it puts forward a series of highly cost-effective solutions that are affordable even where resources are limited. It also emphasises the need for strong health-care systems, improved surveillance and monitoring, and nongovernmental and civil society participation in efforts to reduce the burden of non-communicable disease.

This report, published by the WHO, collates data obtained over 8 years by WHO assessment teams working in 26 African countries. The teams analysed different aspects of national regulatory systems such as management, funding and quality control procedures. Poor regulatory systems in impoverished nations are often blamed for allowing the spread of counterfeit drugs in the developing world. The report says that although mechanisms for drug regulation existed in every country, and there were guidelines for quality-control inspections, these were often not well executed because of a severe lack of resources and staff.

This report explores the role of agricultural growth in reducing and preventing undernutrition — deficiencies in energy, protein, and essential vitamins and minerals.
It describes how agricultural growth increases the capacity of households to produce more nutritious food and to buy more nutritious food by boosting income levels. Agricultural growth also improves nutrition through a broader effect on the economy, such as increasing government revenues to fund education, health, infrastructure, and nutrition intervention programmes.
The report gives an overview of the relationship between nutrition and growth, examines different growth patterns and their nutritional outcomes, and identifies factors that influence this dynamic — such as a country's stage of economic development.
A new paradigm for agricultural development is needed, says the report, where agricultural growth leads not only to increased production and reduced poverty, but also to improved nutrition. It concludes with recommendations for future research, and aims to provide policymakers with knowledge about development and investment strategies that can improve nutritional outcomes.

This report presents evidence that people with mental health conditions meet major criteria for vulnerability and should be targeted for protection by development programmes. Mental illness such as schizophrenia, depression or bipolar disorder are common but largely neglected.
The WHO makes the case that because of their vulnerability, people with mental health problems need to be given opportunities for education and work, and to be included in decisions that affect them.
It argues that mental health should be built into sectoral and broader plans for development, with government agencies, NGOs and other stakeholders playing a key role in ensuring this. To make implementation a reality, interventions and mainstreaming efforts should be funded adequately, and recipients of development aid should be encouraged to address the needs of people with mental health conditions. The report recommends actions as a starting point towards these aims.

This report, published by the Meridian Institute describes the growing interest of developing countries including Brazil, China, India and South Africa, in nanotechnology. The ways nanotechnology applications could solve health, sanitation, and pollution problems and provide faster, cheaper information and communication technology are outlined. The challenges of using and developing nanotechnology for and in developing nations including the roles and responsibilities of different stakeholders are also discussed.
The Meridian Institute says nanotechnology can play a role in achieving the UN Millennium Development Goals. As a result, rich nations should dedicate a reasonable portion of their overseas development assistance to nanotechnology.

This report examines the impact of HIV/AIDS on people's livelihoods in rural areas of Africa, China, Central Asia, India and Russia.
The authors consider labour economising technologies, and set out the potential policy options. They conclude that providing anti-retroviral drugs would have an immediate, and a long-term effect on food security and is the only way of ensuring continued access to labour in the rural sector.

This study assesses whether traditional medicine can contribute to more affordable global healthcare. It uses flowcharts to map out factors such as healthcare infrastructure and social mores that lead much of the developing world to use traditional medicine, and explains the different medicinal systems in use around the world. The author concludes that traditional medicine is a public health asset, provided it can be sufficiently standardised and verified.

Food security is a major challenge in global health. Agriculture will need a significant boost if we are to feed the expected global population of nine billion people in 2050. This detailed report outlines the case for 'sustainable intensification'.
Climate change is already putting pressure on existing agricultural systems and will likely continue to alter rainfall patterns, temperatures and soil quality. But climate change isn't the only culprit — agricultural output has also fallen through growing pesticide resistance and low crop diversity.
The report argues that crop management must take these biological factors into account. But to be sustainable it must also support poor farmers and rural populations. This will require technological approaches underpinned by robust science, says the report.
The authors provide a detailed overview of how climate change will affect food production and the latest genetic techniques available to boost output. No single approach is going to work, and splitting agriculture into different camps — genetically modified or not, for example — will have no traction. The key is to consider the problem holistically and see how different approaches could be combined for the best results.
The report calls for agricultural sciences to be placed at the forefront of innovation, and supports its position in university courses, arguing that if agriculture is to see a revolution, it will need talented scientists.

This report from the WHO assesses the potential for creating early warning systems for vector-borne disease. It reviews the current state of research for several diseases such as dengue fever, leishmaniasis, malaria and West Nile virus.
The report includes an algorithmic framework for developing early warning systems, outlining data requirements and the different components of the system. It also contains two useful tables: one on the sensitivity of different infectious diseases to climate; and one summarising the existing research, identifying in which region the disease is most common, data availability and proposed actions.
A key problem in developing early warning systems, as highlighted by this report, is that non-climatic risk factors such as population immunity and food security strongly affect the potential for a disease outbreak. Equally challenging is the poor disease surveillance in many developing countries — the authors call on these countries to strengthen these systems, to help in the fight against climate change.
The report concludes that it will be important for researchers not to design these systems in isolation — health policymakers should be included at all stages of the design.

This extensive report from the Institute of Medicine of the US National Academies takes on the considerable challenge of understanding how, and to what extent, climate change will affect infectious diseases.
The report provides detailed summaries of current knowledge on diseases such as cholera and rift valley fever. Several pages are devoted to reviewing the latest climate science to contextualise the effect on infectious disease; it also includes several maps on climate anomalies to show how they are linked to disease.
One section highlights methods to assess climate change impacts on infectious diseases. These include analyses of historical records; monitoring programs, especially those that track disease in wild animals; and comparisons of satellite-derived environmental measurements with epidemiological data.
The report concludes with an analysis of the challenges facing policymakers. In many cases, it says, the best public health measures against climate change are those that strengthen health systems in general, such as better training for professionals and better disease surveillance. Policymakers will need to move away from the traditional thinking of individual policies for individual diseases, towards a joined-up approach aimed at tackling "systemic, long-term" stresses that cause a range of effects.

This report, published by the Global Forum for Health Research, tracks global investments in health research and development (R&D).
The authors review global targets and commitments for R&D in health and evaluate how well these are being met. They highlight the differences in funding by region, including analyses from Argentina, China and the United States; and provide a breakdown of investments in R&D for cancer and 20 widespread infectious diseases.
They also describe the different sources of R&D funding, providing data on private, public and not-for-profit investments.
The authors discuss the implications of the current funding climate for future health research and make recommendations for improving research agendas, suggesting that R&D investments must match the health needs of developing countries now and in the future.

This report is the WHO's official record of data produced by its technical programmes and regional offices in close consultation with countries and in collaboration with researchers and development agencies. The WHO produces the statistics to provide an evidence base for strategies to improve global public health.
The report clearly shows that the global burden of disease is shifting from infectious diseases to non-communicable diseases, with chronic conditions such as heart disease and stroke now being the chief causes of death globally. The shifting trends indicate that leading infectious diseases — diarrhoea, HIV, tuberculosis, neonatal infections and malaria — will become less important causes of death globally over the next 20 years.
The report documents in detail "the levels of mortality in children and adults, patterns of morbidity and burden of disease, prevalence of risk factors such as smoking and alcohol consumption, use of health care, availability of health care workers, and health care financing."

This joint publication between the World Health Organization and the Global Forum for Health Research reveals mental health research capacity in 114 low-income and middle-income countries in Africa, Asia, and Latin America and the Caribbean. The extensive review identified over 10,000 articles, 4,633 mental health researchers and 3,829 other stakeholders. The authors argue that this is "the first systematic attempt to confirm the pressing needs of improving research capacity in mental health".
The publication provides useful details in table and charts, analysed by group of stakeholders and by region, on topics such as: researchers' profiles; priority-setting process; amount and type of research production; services and technical support available to them; courses and trainings offered; funding patterns; and dissemination of research findings. The appendix provides two extensive lists — by country — of policy and practice that resulted from research evidence, as well as research evidence that was never translated into policy and practice.
Nine recommendations indicate how the management of mental health research can be strengthened so that it meets the national needs of the countries as well as contributes to the global fund of knowledge. The authors say their report thus enables evidence-based decision-making in funding and priority setting in the area of mental health research in low-income and middle-income countries.

These consist of two reports: SuRF1(Surveillance of risk factors related to non-communicable diseases: current status of global data) and SuRF2 (Surveillance of chronic disease risk factors: country-level data and comparable estimates).
These reports are the result of a large WHO project to set up for the first time a global database of the prevalence of risk factors for non-communicable diseases collected from WHO member states. The first report is largely a collection of the country profiles; the second analyses the data to produce comparable estimates for risk factor prevalence in the countries. The WHO designed this as an advocacy tool to highlight where primary prevention and health promotion need to be directed.
The eight risk factors were chosen because they are easily measurable and theoretically can be changed through prevention efforts. They are: tobacco and alcohol use, patterns of physical inactivity, low fruit/vegetable intake, obesity (as measured by BMI), blood pressure, cholesterol and diabetes (measured by blood glucose).
The second report presents country-level estimates for overweight/obesity and systolic blood pressure. It also shows the attributable mortality and disease burden from all causes of death due to these overweight and high blood pressure for the 11 most populated countries.
