The Triumph and Tragedy of Tobacco Control: A Tale of Nine Nations

The use of law and policy to limit tobacco consumption illustrates one of the greatest triumphs of public health in the late twentieth and early twenty-first centuries, as well as one of its most fundamental failures. Overall decreases in tobacco consumption throughout the developed world represent millions of saved lives and unquantifiable suffering averted. Yet those benefits have not been equally distributed. The poor and the undereducated have enjoyed fewer of the gains. In this review, we build on existing tobacco control scholarship and expand it both conceptually and comparatively. Our focus is the social gradient of smoking both within and across borders and how policy makers have been most effective in limiting smoking prevalence among the more privileged segments of society. To illustrate that point, we reference a range of literature on tobacco taxation, advertising, and public smoking in five economically advanced democracies—France, Germany, Japan, the United Kingdom, and the United States—and four less developed nations—India, China, Brazil, and South Africa—that together comprise 40% of the world’s population

Problems and Prospects: Public Health Regulation of Dietary Supplements

Dietary supplements are a global business worth more than US$100 billion annually. These supplements are taken by up to 50% of adults and perhaps one-third of children in economically advanced economies. Definitions of dietary supplements differ from country to country, and regulation is generally lax and often seems to be directed more toward promoting commerce than protecting public health. Supplements may directly cause toxic reactions or may interact with other supplements or pharmaceuticals. Some supplements are found to have been contaminated with heavy metals, and others do not contain the expected quantities of active ingredients. In general, supplements are not needed except in cases of established deficiencies, and excess of some nutrients can increase cancer rates. There are important public health reasons for taking some supplements, including folate and iodine in pregnancy. This review discusses the public health concerns associated with dietary supplements and suggests directions for further regulation

The authority of next-of-kin in explicit and presumed consent systems for deceased organ donation: an analysis of 54 nations

Background. The degree of involvement by the next-of-kin in deceased organ procurement worldwide is unclear. We investigated the next-of-kin’s authority in the procure-ment process in nations with either explicit or presumed consent. Methods. We collected data from 54 nations, 25 with presumed consent and 29 with explicit consent. We char-acterized the authority of the next-of-kin in the decision to donate deceased organs. Specifically, we examined whether the next-of-kin’s consent to procure organs was always required and whether the next-of-kin were able to veto procurement when the deceased had expressed a wish to donate. Results. The next-of-kin are involved in the organ procure-ment process in most nations regardless of the consent principle and whether the wishes of the deceased to be a donor were expressed or unknown. Nineteen of the 25 nations with presumed consent provide a method for individuals to express a wish to be a donor. However, health professionals in only four of these nations responded that they do not override a deceased’s expressed wish because of a family’s objection. Similarly, health profes-sionals in only four of the 29 nations with explicit consent proceed with a deceased’s pre-existing wish to be a donor and do not require next-of-kin’s consent, but caveats still remain for when this is done. Conclusions. The next-of-kin have a considerable influ-ence on the organ procurement process in both presumed and explicit consent nations
