Monoclonal antibodies, of wide application innephrology <strong>and</strong> oncology, human transference fac<strong>to</strong>r <strong>and</strong>growth fac<strong>to</strong>r used in <strong>the</strong> treatment of cancer, proctitis <strong>and</strong>ulcers, <strong>and</strong> Surfacen for <strong>the</strong> treatment of respira<strong>to</strong>ry distressof newborn are also included in <strong>the</strong> range of Cuban products.UltramicroELISA, a Cuban diagnostic technology forneonatal <strong>and</strong> infectious disease screening, is widely used in<strong>the</strong> country, supporting <strong>the</strong> epidemiological surveillance ofseveral infectious diseases such as dengue, HIV, HBV <strong>and</strong>HCV <strong>and</strong> <strong>the</strong> screening in all pregnant women of neonataldisorders such as congenital hypothyroidism, phenylke<strong>to</strong>nuria,galac<strong>to</strong>semia <strong>and</strong> o<strong>the</strong>r malformations. In <strong>the</strong> period 1982 <strong>to</strong>2006, more than 3 million pregnant women were screened<strong>and</strong> 6748 congenital malformations were detected .24 . Also,more than 2.7 million (100%) of newborns were studied,detecting 731 with congenital hypothyroidism. Thesechildren were treated early, avoiding cretinism.UltramicroELISA has also been fundamental for <strong>the</strong> bloodcertification programme.A relatively recent national investigation allowed screeningof all individuals with some disability. The physical <strong>and</strong>psychological characteristics of <strong>the</strong>se persons <strong>and</strong> <strong>the</strong>contributing fac<strong>to</strong>rs for intellectual or mental disability weredetermined. In <strong>the</strong> Medical Genetic services, extended <strong>to</strong> allprovinces of <strong>the</strong> country as part of <strong>the</strong> National Programmeof Attention <strong>to</strong> Persons with Some Disability <strong>and</strong> <strong>the</strong>programme of Medical Genetics, 29 genetic pathologies <strong>and</strong>more than 50 metabolic disorders are diagnosed.

Research resourcespoliomyelitis <strong>and</strong> given <strong>the</strong> particular success of <strong>the</strong> Cubanvaccination strategy, several investigations supporting globalpolio eradication have been conducted in our country at <strong>the</strong>request of <strong>the</strong> World Health Organization (WHO) <strong>and</strong> <strong>the</strong>Pan American Health Organization (PAHO), allowingdemonstration of <strong>the</strong> circulation-time of <strong>the</strong> vaccine viruses in<strong>the</strong> environment after <strong>the</strong> oral vaccination <strong>and</strong> <strong>the</strong> immunityof <strong>the</strong> inactivated vaccine. This new knowledge <strong>and</strong> <strong>the</strong>investigations in course will allow improved definition of <strong>the</strong>strategy for global polio vaccination after eradication 25 . Newfindings of global impact related <strong>to</strong> dengue hemorrhagic fever(DHF), have been reported by Cuban scientists. Theconfirmation of secondary infection as a risk fac<strong>to</strong>r for DHF,<strong>the</strong> influence of <strong>the</strong> interval between infections <strong>and</strong> <strong>the</strong> roleof ethnicity <strong>and</strong> chronic diseases are only some examples 20 .Flexibility also characterizes Cuban science, allowingincorporation of new <strong>to</strong>pics in <strong>the</strong> research agenda dependingon <strong>the</strong> epidemiological national <strong>and</strong> international situation.The preparation of <strong>the</strong> country in terms of surveillance,diagnosis <strong>and</strong> research <strong>to</strong> face new global epidemics such asWest Nile Fever, SARS <strong>and</strong> Avian Flu are recent examples.Current research needs <strong>and</strong> agendaAt present, <strong>the</strong> Cuban population shows a very high <strong>health</strong>level with <strong>the</strong> Millennium Development Goals alreadyaccomplished 26,27,28 . However, <strong>the</strong> country is working <strong>to</strong> <strong>reach</strong>new goals, with an infant mortality ratio of less than fivedeaths per 1000 live births, life expectancy at birth of 80years <strong>and</strong> quality of life improvement being <strong>the</strong> mostimportant new targets. At this new stage, research occupiesa leading place due <strong>to</strong> its direct impact on <strong>health</strong>development. To achieve <strong>the</strong>se new goals, differentinvestigations are under development, notable ones beingactive screening of risk groups <strong>and</strong> of <strong>the</strong> open population fordiseases that are <strong>the</strong> major causes of mortality. Theseinvestigations will allow early detection of <strong>the</strong> illness in order<strong>to</strong> apply <strong>the</strong> appropriate treatment <strong>and</strong> management ofpatients, avoiding disability <strong>and</strong> death. Supporting this newstrategy, <strong>the</strong> accessibility of <strong>the</strong> <strong>health</strong> system has increasedby <strong>the</strong> introduction of advanced technology at <strong>the</strong> primaryheath care level.A <strong>to</strong>tally different <strong>health</strong> picture is observed in many o<strong>the</strong>rpoor countries. According <strong>to</strong> WHO, <strong>and</strong> as an example, Africashows an infant mortality per 1000 live births of 100, a lifeexpectancy at birth of 47 years for males <strong>and</strong> 49 for females,<strong>and</strong> HIV/AIDS <strong>and</strong> TB constitute major causes ofmortality 29,30,31 . Due <strong>to</strong> this serious situation, a new agenda forresearch <strong>and</strong> <strong>the</strong> implementation of research findings isneeded at <strong>the</strong> global level. In this sense, Cuba is developinga new model of regional <strong>and</strong> international cooperation in<strong>health</strong>, education <strong>and</strong> science. Currently, <strong>the</strong> country hosts22 000 students from developing countries in its medicalschools <strong>and</strong> more than 32 000 Cuban collabora<strong>to</strong>rs labour inmore than 80 countries. From <strong>the</strong> 1960s, more than132 000 <strong>health</strong> workers collaborated in 102 countries of <strong>the</strong>developing world. This model of collaboration is having adirect impact on streng<strong>the</strong>ning human capacities, <strong>the</strong>development of scientific research <strong>and</strong> public <strong>health</strong>. ❏Gustavo Kourí is a researcher, professor <strong>and</strong> Vice-President of<strong>the</strong> Cuban Academy of Science.
