The Wellcome Trust purchase fenofibrate 160 mg line, set up as a charity on the death of Henry Wellcome in 1936 order fenofibrate 160 mg on-line,t is now one of the biggest medical research funders in Europe proven fenofibrate 160mg. Up until 1986 the Trust controlled 100% of the shares of the Wellcome drug producing company. In 1986, however, the Trust sold off just over 25% of Wellcome plc, floating 210,800,000 shares at 120p each. In July 1992 there was a second share flotation when the Trust disposed of a further 288 million shares, so reducing its holding to 40%. This second flotation was the largest for a private company ever seen in Britain; it raised £2. Henry Wellcome nominated two Americans to handle the legal matters relating to his will and the continuing Wellcome empire. Following the first share flotation in 1986, Wellcome went from strength to strength. Dragged into the Twenty First Century For years Wellcome was regarded as a qualitatively different type of company from other drug companies; its Trust and its links within the British ruling elite gave it access to both academia and government on an unparalleled scale. With the changing economic climate of the eighties, however, even Wellcome found it difficult to keep up the front of a benign and philanthropic enterprise. This was probably precipitated by the move in the late seventies into the new and profitable area of genetic engineering and medical biotechnology, as well as by American pressure on the Foundation to become more market orientated. In 1982, the Company made a first move towards the area of biological research, setting up Wellcome Biotechnology. In October of that year Wellcome announced its desire to sell its human vaccine production, which finally went to the small British firm Medeva plc. He pronounced that scientifically interesting projects were to take a back seat to those with commercial promise. He instigated a vigorous cost cutting programme, which included the loss of 40 head office jobs. Between them they launched a cost control programme, tightening capital expenditure controls, capping research and development spending and trying to improve efficiency. More than any other Anglo-American company, Wellcome has pursued an economic policy overshadowed by this relationship, a policy principally shaped by Rockefeller financial and political interests. Seventy years after the beginning of public philanthropic involvement of Rockefeller interests in medical research in Britain and America, Wellcome still represents one of their major British bases. Sir Oliver Franks, who died in 1992, was Chairman of the Wellcome Trust for almost twenty years between 1965 and 1982; he had an impeccable Rockefeller background. Originally a civil servant and then a banker, he was a Trustee of the Rhodes Trust between 1957 and 1973. From 1947, on its inception, until 1979, he was a Trustee and later Chairman of the Pilgrim Trust, an archetypal Anglo-American cultural and philanthropic organisation. From 1961 to 1970, almost concurrent with his time at the Wellcome Trust, he was a Trustee of the Rockefeller Foundation. Lord Swann was a member of the Ditchley Foundation, which organises meetings, conferences and seminars attended by defence and security experts from America and Britain. Sir Alistair Frame, who became Chairman of the Wellcome Foundation in 1985, was previously the Director of Rio-Tinto-Zinc, one of the most committed Anglo-American corporations. Unlike other pharmaceutical companies, the Wellcome complex plays a commanding role in the British industrial military complex. The Commission, set up by David Rockefeller in the early seventies, has acted since then as a shadow world economic policy meeting. Made up of industrialists, academics and politicians, especially in the field of foreign policy, it has at its core a group of multinationals whose corporate management is determined to break down all boundaries to world capitalism and its trade. The Commission has discussed and resolved questions about the most important foreign policy initiatives of the last twenty years, usually decades before these questions entered the public domain. Pursuing trade exchanges and bases in communist countries, it opened up factories and marketing windows in Hungary, the Soviet Union and Romania. In March 1989, as a sign of philanthropic goodwill, Wellcome sent 75 tons of baby products worth £500,000 to Poland. All these contemporary strategies, consolidation in Western Europe, integration and ascendancy in Eastern Europe, capitalising on the run-down communist economies, and development in Japan, are global strategies of the Rockefeller Trilateral Commission. The object of developing trade with Eastern Europe, has been the ending of the cold war and the integration of economic and financial structures across Europe. Japan is the third staging post of the Trilateral Commission, which intends to integrate the Japanese markets with those of Europe and America. The Crisis of Profit and Ethics Few pharmaceutical companies have avoided the public backlash which comes with damaging or unpopular drugs: Wellcome is no exception. By the early seventies, Wellcome was involved in major market conflicts over drugs which were said to have adverse effects. In 1973, both Wellcome and Burroughs Wellcome were criticised over their antibacterial drug Septrin (United Kingdom) or Septra (United States) when a number of articles and papers appearing in 12 America and in Canada suggested that other antibacterials were safer for certain conditions. During this trial, it was never an agreed matter of fact that the actual vaccine given to Susan Loveday was the one made by Wellcome. After a five-month hearing, the judgement in the Loveday case was given in April 1988.

But despite the hum an loss cheap fenofibrate 160mg without prescription, enorm ous in some cases order fenofibrate 160 mg fast delivery, people in most affluent countries have adopted to urban conditions (and trusted 160 mg fenofibrate, of course, the conditions have been im proved as well). T o use a concrete example, the devas­ tating disease known as “consum ption” in the nineteenth century is now understood to have been pulm onary tuber­ culosis. Although the virulence of the bacilli is as great now as it was then, our adaptive response has come to blunt its 24 The Impact of Medicine severity. In short, both the types of disease and the patterns of disease reflect prevalent conditions in a given culture. To quote Rene Dubos: W ithout question, nutritional and infectious diseases account for the largest percentage of morbidity and mortality in most underprivileged countries, especially in those just becoming industrialized. Undernutrition, protein deficiency, malaria, tuberculosis, infestation with worms, and a host of ill-defined gastrointestinal disorders are today the greatest killers in these countries, just as they used to be in the Western world one century ago. In contrast, the toll taken by malnutrition and infection decreases rapidly wherever and whenever the living standards improve, but other diseases then become more prev­ alent. In prosperous countries at the present time, heart dis­ eases constitute the leading cause of death, with cancers in the second place, vascular lesions affecting the central nervous system in the third, and accidents in the fourth. Increasingly also, persons who are well fed and well sheltered suffer from a variety of chronic disorders, such as arthritis and allergies, that do not destroy life but often ruin it. Increased longevity, re ­ ductions in m aternal and infant m ortality, and o th er related im provem ents are not owed to m edicine. Diseases associated with industrialization— largely infectious disorders— were tam ed in developed cultures. If anything, due to o u r incapacity to adjust to the stresses o f postindustrial society, health status is tapering. Jo h n Powles, in a paper on the ebbs and flows in health and disease patterns, sum m arizes the point: Industrial populations owe their current health standards to a pattern of ecological relationships which serves to reduce their vulnerability to death from infection and to a lesser extent to the capabilities of clinical medicine. Unfortunately, this new way of life, because it is so far removed from that to which man is adapted by evolution, has produced its own disease burden. John Cassel, a noted epidemiologist at the Uni­ versity o f N orth Carolina, has argued for m ore research focused on the relationship between disease rates and social phenom ena such as industrialization, stress, and congestion. He points to the m ajor shifts in disease patterns which have been portrayed and concludes: Despite intensive research, the explanation for the genesis of these changes in disease patterns have proved so far to be relatively unsatisfactory. It is a sad com m entary on biomedical research that m ore atten­ tion has not been given to the relative impact on health of many variables, including medical care. It is generally agreed that contam inated food, degraded air and water, garbage and filth, and drafty, cold housing can cause illness. A 1969 study focused on the “production function” in health—its effectiveness in terms of what it is supposed to do. T he study revealed that factors associated with income and education have a significant impact on health status. T he effect of educa­ tion on health was illustrated by a National B ureau of Economic Research study that exam ined interstate differen­ tial and age-adjusted death rates. O ne finding was that as large a reduction in mortality is associated with the expendi­ ture of one m ore dollar for education as an additional dollar spent on medical care.

In com paring treatm ent, prevention, inform ation, and research, he found that both literacy (as a proxy for inform ation) and potable water (as a proxy for prevention) had high impacts on life expectancy in all nations in the The Impact of Medical Care on Health Status 27 W estern hem isphere. Ginzberg approvingly quotes an earlier report stressing the im portance of nutrition for physical development: a diversified enriched diet will probably contribute to the health of the population. Victor Fuchs, in an unpublished paper, points out that affluence frequendy leads to excessive consum ption, even engorgem ent of some goods, such as rich foods, that adversely affect health. A link between nutrition and health has also been estab­ lished by studies contrasting the impact on health o f nutri­ tion and medical care. In one village, only im proved m edi­ cal care was introduced; in another, only nutrition was enriched; in a third, both medical care and diet were en­ hanced. T he results show that nutrition was far m ore significant in im proving health than the provision o f medical care. In both cases the results, while tentative and crude, tend to prove the worth o f certain disease detection program s. In general, program s that provide increased services for m others and children in areas that have traditionally had few medical services have the greatest payoff. Fluoridation program s, which are relatively in­ expensive, produce benefits (in terms of reduced num bers of cavities) in m ore than 300,000 children for an expendi­ ture o f $10 million. Treatm ent-oriented program s for the same am ount o f money potentially benefit only 18,000 to 44,000 children. No cure is known for schizophrenia, the most prevalent psychosis, although proponents of megavitamin treatm ent profess to have had some success. T he use of tranquilizers and shock therapy has also had some impact on reducing hospitalization rates.
