SARS Reference had more than 200 buy florinef 0.1 mg free shipping,000 readers in 20 months order florinef 0.1mg fast delivery, because it was free of charge buy florinef 0.1 mg amex. It was translated into 8 languages because it was free of charge and the copyright had been removed. SARS Reference is in third place on the Google list after the CDC and the WHO, because it is known throughout the world. SARS Reference was reviewed twice, in Science and in the British Medical Journal (Page 70), because it showed new ways of publishing medical information. The decision has been made: we are going to write a medical textbook and publish it both as a book and on the internet. But how precisely do we set about approaching this project? Do we have the publishing skills to achieve success? In the last few years, doctors have seen how amazingly self-sufficient they have become in spreading medical 15 1. Whether we wanted to or not, we have all become experts in word processing. Think back: how many doctors were familiar with the layout of letters on a typewriter 20 years ago? Better still: we are not only adept at word processing but have also become practised layout designers. Anyone who has published scientific articles in medical journals has learned that he must “format” his texts in accordance with strict regulations. After all, the work performed in the medical publishing houses must be reduced to a minimum. What is left for medical publishing houses to do in this context? We type, our word-processing software typesets, PDF prints and the Internet distributes the online version. The only problem left would be distribution, which – as we will see later on – is a problem which can be solved for medical textbooks, 90% of which are sold in a relatively small number of specialised bookstores. So, let us put the question more precisely: what do we do if we have a finished manuscript? Do we go to a traditional publishing house or is it more beneficial to produce the book in our own garage? There is sometimes a sense of shame at the idea of publishing a written text ourselves. The argument: publishing houses are seen as a supervisory body, and it is this supervision that awards our texts the seal of approval, sanctifies our work, and renders sacred our Opus urbi et orbi. This was not true in the past – and is even less so today.

Note: For every 10-fold increase in gross national income (GNI) per person buy cheap florinef 0.1 mg line, the number of scientifc publications (per person) increases by a factor of about 50 at best (actually by 105/3 = 46 generic 0.1 mg florinef with amex, diagonal line) cheap florinef 0.1 mg. While some countries exploit maximum productivity, lying close to the diagonal line, many lie well below it, indicating that there is unfulflled research potential, given their national wealth. Some of these coun- tries have smaller populations (< 20 million, blue circles), but not all. The unfulflled potential for research in one large country (Philippines) is indicated by the vertical arrow.

The Global Strategy and Plan of Action on Public Health, Innovation and Intellectual Property Born out of concern among low- and middle-income countries about inequitable access to the products of research, the Commission on Intellectual Property Rights, Innovation and Public Health was established to promote innovation and access to medicines. The work of the Commission led to the Global Strategy and Plan of Action on Public Health, Innovation and Intellectual Property (GSPA-PHI), which was approved by the World Health Assembly in 2009 (68). The GSPA-PHI consists of eight elements that aim to promote innovation, build capacity, improve access and mobilize resources. Work is under way in several areas related to GSPA-PHI, such as the local production of medical products and technology transfer (element 4), building capacity in the management and use of intellectual property in favour of public health (element 5), reporting on models for sustainable financing and better coordination of research and development (element 7) through WHO expert working groups; and the establishment of monitoring and reporting systems (element 8), such as research observatories (Chapter 4) (69, 70). Effective implementation of the GSPA-PHI depends on the robustness of the national health research system in each country. Over time, monitoring and evaluation will reveal whether the GSPA-PHI leads to increased innovation and more affordable and equitable access to the benefits and products of research, especially in low- and middle- income countries. In total, more than however, methods of preventing and treating US$ 100 billion is spent globally on health noncommunicable diseases, largely developed research each year (71).
