Make science evolve into a One Health approach to improve health and security: a white paper.

The World One Health Congresses are biennial gatherings of approximately 1500 professionals from relevant international organisations, OIE, FAO, WHO, World Bank, leading scientific experts and researchers in the field of One Health, animal production and trade, food safety, animal health, human health and environmentology/ecology, government representatives in public health, human health, food safety, environmental health and global health security. The Congress is organized by the One Health Platform. This white paper summarizes highlights of the 5th International One Health Congress in Saskatoon, Canada, June 2018 and serves as a roadmap for the future, detailing several concrete action points to be carried out in the run-up to the 6th World One Health Congress in Edinburgh, Scotland, June 2020.

Biosecurity policies at international life science journals.

The prospect of bioterrorism has raised concerns about the potential abuse of scientific information for malign purposes and the pressure on scientific publishers to prevent the publication of "recipes" for weapons of mass destruction. Here we present the results of a survey of 28 major life science journals--20 English-language international journals and 3 Chinese and 5 Russian journals--with regard to their biosecurity policies and procedures. The survey addressed the extent to which life science journals have implemented biosecurity procedures in recent years, how authors and reviewers are advised about these procedures and the underlying concerns, and what the practical experiences have been. Few of the English-language publishers and none of the Russian and Chinese publishers surveyed implement formal biosecurity policies or inform their authors and reviewers about potentially sensitive issues in this area.

Pharmacogenetics, adverse drug reactions and public health.

Adverse drug reactions (ADRs) are a major public health problem. Pharmacogenetic testing prior to drug treatment is supposed to considerably alleviate this problem. The state of pharmacogenetic development was assessed by a systematic literature review, supplemented by expert interviews. Analysis of three case examples revealed that - with the exception of thiopurine methyltransferase (TPMT) - studies are lacking which unambiguously prove the clinical value of pharmacogenetic testing. Testing can prevent some, but by far not all ADRs. Since it does not compensate for clinical monitoring, pharmacogenetics can be regarded as add-on technology, applied in addition to established methods. A non-representative, explorative survey conducted amongst members of the German Society of Laboratory Medicine revealed that the demand for testing is limited and has not increased much, although a certain increase is expected in the future.

Individualized pharmacogenetic therapy: a critical analysis.

OBJECTIVE: Individualized, or personalized, therapy is highlighted as the declared goal of pharmacogenetics. In this paper, the content and significance of the individualization concept are analyzed. METHOD: Our analysis is based on a systematic reading of the current literature pertinent to pharmacogenetics. RESULTS: This analysis reveals that the pharmacogenetic understanding of individualization is based on a biomechanistic paradigm. In contrast to a notion of individualized therapy based on a biopsychosocial paradigm, this biomechanistic concept does not provide for individualization in psychosocial terms, but instead leads to the stratification and classification of patient populations. This finding does not necessarily cast doubt on the efficacy of pharmacogenetics, but does call its underlying ideology into question. CONCLUSION: The term 'individualization of therapy' does not reflect the real potential of pharmacogenetics, but instead represents a widely used and theoretically unjustified publicity slogan.

Prospects and limits of pharmacogenetics: the thiopurine methyl transferase (TPMT) experience.

Thiopurine drug metabolism is a quintessential case of pharmacogenetics. A wealth of experimental and clinical data on polymorphisms in the thiopurine metabolizing enzyme thiopurine methyl transferase (TPMT) has been generated in the past decade. Pharmacogenetic testing prior to thiopurine treatment is already being practiced to some extent in the clinical context, and it is likely that it will be among the first pharmacogenetic tests applied on a regular basis. We analyzed the published TPMT data and identified some lessons to be learned for the future implementation of pharmacogenetics for thiopurines as well as in other fields. These include the need for comprehensive and unbiased data on allele frequencies relevant to a broad range of populations worldwide. The nature and frequency of TPMT gene polymorphisms in some ethnic groups is still a matter of speculation, as the vast majority of studies on TPMT allele distribution are limited to only a small subset of alleles and populations. Secondly, an appreciation of the limits of pharmacogenetics is warranted, as pharmacogenetic testing can help in avoiding some, but by far not all adverse effects of drug therapy. An analysis of six clinical studies correlating adverse thiopurine effects and TPMT genotype revealed that an average of 78% of adverse drug reactions were not associated with TPMT polymorphisms. Pharmacogenetic testing will thus not eliminate the need for careful clinical monitoring of adverse drug reactions. Finally, a careful approach toward dose increases for patients with high enzyme activity is necessary, as TPMT-mediated methylation of thiopurines generates a possibly hepatotoxic byproduct.

Closing loopholes in the Biological Weapons Convention.

The Biological and Toxin Weapons Convention (BTWC) received two major blows in the past months. Negotiations for a protocol to strengthen the BTWC came to a halt and the Fifth Review Conference was unable to reach agreement on a final declaration. In addition, ongoing research projects, predominantly in the United States, are threatening to undermine the comprehensive ban on the development, production and use of biological weapons. This article provides two examples of research that exploit perceived loopholes in the BTWC or impinge on the scope of the Convention, namely the planned use of biological agents for forced drug eradication and the development of anti-material agents.
