Book review of Introduction to U.S. Health Policy: The Organization, Financing and Delivery of Health Care in America by Donald A. Barr

Donald A. Barr's Introduction to U.S. Health Policy: The Organization, Financing, and Delivery of Health Care in America (second edition, 2007) offers a lucid and informative overview of the U.S. health system and the dilemmas policy makers currently face. Barr has provided a balanced introduction to the way health care is organized, financed, and delivered in the United States. The thirteen chapters of the book are quite comprehensive in the topics they cover. Even those knowledgeable about the U.S. health care system are likely to find much to stimulate their thinking in the text. The book can also appropriately serve as a basic text for a health policy course or in the medical or nursing school curriculum

Implications d'AXIN2 et de l'instabilité microsatellite dans le développement des tumeurs du cortex-surrénalien

Les lésions tumorales cortico-surrénaliennes sont majoritairement des adénomes bénins et très rarement des carcinomes. Les altérations génétiques impliquées dans le développement des tumeurs cortico-surrénaliennes sporadiques, plus particulièrement au stade malin, demeurent à ce jour très peu connues. Lors de travaux récents menant à l’identification d’altérations génétiques de β-CATÉNINE nous avons constaté que plusieurs tumeurs présentaient une accumulation nucléo/cytoplasmique de la protéine β-CATÉNINE sans toutefois contenir de mutations pour ce gène. Nous avons donc émis l’hypothèse que, comme pour d’autres types de cancers, d’autres composants de la voie de signalisation Wnt/β-CATÉNINE, tel qu’AXIN2, pourrait être impliqués dans le développement des tumeurs du cortex surrénalien. De plus, plusieurs aberrations dans l’expression d’AXIN2 et de β-CATÉNINE sont associées à des tumeurs présentant de l’instabilité microsatellite dans d’autres types de cancer, notamment le cancer gastrique et colorectal. Nous avons donc étudié une cohorte de 30 adénomes, 6 carcinomes, 5 AIMAH, 3 hyperplasies ACTH-dépendante et 5 PPNAD ainsi que les lignées cellulaires de carcinomes cortico-surrénaliens humains H295R et SW13. Une étude préliminaire du statut MSI a également été réalisée sur 10 tumeurs contenant une mutation pour AXIN2 et/ou β-CATÉNINE. Nous avons trouvé des mutations d’AXIN2 dans 7% des adénomes (2/30) et 17% des carcinomes (1/6) cortico-surrénaliens. L’analyse fonctionnelle des mutations par immunohistochimie, analyse western blot et analyse de RT-PCR en temps réel a révélé une diminution de l’expression d’AXIN2 associée à cette mutation. L’analyse préliminaire MSI a démontré 1 échantillon AIMAH MSI-H, c’est-à-dire instable pour le locus BAT-25 et BAT-26 et 3 autres adénomes sécrétant de l’aldostérone instables seulement pour le locus BAT-26. Ainsi, ces travaux permirent d’identifier une nouvelle altération génétique associée au développement des tumeurs du cortex surrénalien en plus de rapporter pour la première fois la présence de MSI-H dans ce type de tumeurs.Adrenocortical lesions are mostly benign tumors and rarely carcinomas. From now on, genetic alterations implicated in sporadic adrecocortical tumour development remains largely unknown. In our previous work leading to identification of genetic alterations in β-catenin, we observed that many tumors presented a nucleo/cytoplasmic accumulation of β-catenin protein without β-catenin mutations. Thus, we hypothesised that, as for many others cancers, others components of the Wnt/ β-catenin signalling pathway, as AXIN2, are implicated in development of adrenocortical tumors. Also, many aberrations in AXIN2 and β-catenin expression have been reported in association with microsatellite instability in other types of cancers like gastroinstestinal and colorectal cancer. We have studied 30 adenomas, 6 carcinomas, 5 AIMAH, 3 ACTH-dependant hyperplasias and 5 PPNAD as well as the human carcinoma cancer cells lines H295R and SW13. Preliminary study for MSI was also realised on 10 tumors harbouring AXIN2 and/or Β-CATENIN mutations. We have found AXIN2 mutations in 7% of adrenocortical adenomas (2/30) and 17% of adrenocortiocal carcinomas. Functional analysis of this mutation by immunohistochemical, western blot and real-time RT-PCR analysis revealed a down-regulation of AXIN2 expression associated with this mutation. Preliminary analysis of MSI results in 1 AIMAH sample MSI-H, which means instable for BAT-25 and BAT-26 locus, and 2 aldosterone adenomas were unstable for BAT-26 locus. This work identified a new genetic alteration involved in adrenocortical tumour development and report for the first time MSI-H in this type of tumor

From conceptual pluralism to practical agreement on policy: global responsibility for global health.

BACKGROUND: As the human cost of the global economic crisis becomes apparent the ongoing discussions surrounding the post-2015 global development framework continue at a frenzied pace. Given the scale and scope of increased globalization moving forward in a post-Millennium Development Goals era, to protect and realize health equity for all people, has never been more challenging or more important. The unprecedented nature of global interdependence underscores the importance of proposing policy solutions that advance realizing global responsibility for global health. DISCUSSION: This article argues for advancing global responsibility for global health through the creation of a Global Fund for Health. It suggests harnessing the power of the exceptional response to the combined epidemics of AIDS, TB and Malaria, embodied in the Global Fund to Fight AIDS, Tuberculosis and Malaria, to realize an expanded, reconceptualized Global Fund for Health. However this proposal creates both an analytical quandary embedded in conceptual pluralism and a practical dilemma for the scope and raison d'etre of a new Global Fund for Health. To address these issues we offer a logical framework for moving from conceptual pluralism in the theories supporting global responsibility for health to practical agreement on policy to realize this end. We examine how the innovations flowing from this exceptional response can be coupled with recent ideas and concepts, for example a global social protection floor, a Global Health Constitution or a Framework Convention for Global Health, that share the global responsibility logic that underpins a Global Fund for Health. CONCLUSIONS: The 2014 Lancet Commission on Global Governance for Health Report asks whether a single global health protection fund would be better for global health than the current patchwork of global and national social transfers. We concur with this suggestion and argue that there is much room for practical agreement on a Global Fund for Health that moves from the conceptual level into policies and practice that advance global health. The issues of shared responsibility and mutual accountability feature widely in the post-2015 discussions and need to be addressed in a coherent manner. Our article argues why and how a Global Fund for Health effectuates this, thus advancing global responsibility for global health
