Health systems in developing nations aren't ready for the diseases that accompany ageing, writes Priya Shetty.

Healthcare policies and research strategies in developing countries must adapt to the new big killers, says Priya Shetty.

It is time to turn our attention to mental health in poor countries, argues Priya Shetty.

Richard Horton, editor of The Lancet, discusses the implications of news that maternal deaths have dropped by nearly a third since 1980.

Maternal health needs a new, pragmatic, research-led approach targeted specifically for developing countries, says Priya Shetty.

Policymakers must think outside the box to strengthen clinical research networks for global health, says Harvard researcher Jeff Blander.

Understanding how neglected tropical diseases affect chronic diseases can help inform health policies, say Peter Hotez and Abdallah Daar.

African governments are ill-prepared to address the continent's growing cancer burden, warn Hany Besadaand and Vadim Ermakov.

Cancer care in Africa faces the same challenges as general healthcare, but also needs local data and targeted solutions, says Twalib Ngoma.

To stem the spread of obesity, we must study the web of commercial interests and strategies driving it, says Jonathan Wells.

We need better global monitoring for chronic diseases before we can really tackle the risks factors and prevent illness, says Colin Mathers.

Developing nations must stop aping the North's mental health services and use strategies tailored to their own needs, says Vikram Patel.

Non-communicable disease treatment has a lot to learn from tuberculosis control programmes, say Anthony D. Harries and colleagues.

Hypertensive disease kills large numbers in developing countries, but efforts to tackle it are lacking, say Stephen MacMahon and colleagues.

The West should eradicate diseases spread to Latin America by the transatlantic slave trade, say Patrick J. Lammie and colleagues.

Good quality tropical diseases research exists, but the mechanisms surrounding it need reform, say a series of Nature articles.

Denise DeRoeck and colleagues want to see research into typhoid fever placed firmly back on the international agenda.

A new vaccine could prevent millions of cervical cancer deaths if priced appropriately, argue Jan M. Agosti and Sue J. Goldie.

Tackling chronic diseases in developing countries must be made a priority, say Gerard F. Anderson and Edward Chu.

Funds allocated to fight HIV/AIDS, TB and malaria could be used to tackle neglected diseases that affect millions, say David Molyneux and colleagues.
