Free Public Workshop: Application of Evidence-based Methods to Construct Mechanistic Frameworks for the Development and Use of Non-animal Toxicity Tests
June 12, 2019, McMaster University, Hamilton, Ontario, Canada
EBTC/GRADE Working Group conducted a free public workshop entitled: “Application of evidence-based methods to construct mechanistic frameworks for the development and use of non-animal toxicity tests.” The goal of this workshop was to bring together international regulatory bodies (US EPA, EFSA, OECD, NIEHS, risk assessors, academic scientists, and industry) to explore, via discussion of related themes, how systematic review methods and AOP concepts could be combined to develop and use non-animal test methods for predicting the toxicity of chemical substances in an evidence-based manner. The workshop preceded the annual GRADE meeting June 13-14 in Hamilton, ON.
The plenary talks at this workshop have been recorded and are now available to listen to here: https://youtu.be/NNa0r2qL4pI

Assuring the Quality of Systematic Reviews Published in Toxicology and Environmental Health Journals
May 29-31, 2019, Research Triangle Park, North Carolina, USA
t4 (Transatlantic Think Tank for Toxicology) workshop for toxicology journal editors: “Assuring the Quality of Systematic Reviews Published in Toxicology and Environmental Health Journals.” This workshop brought together editors to develop a joint strategy to assure the quality of the systematic reviews that journals in the environmental health and toxicological sciences are publishing. This was an invitation-only event. Proceedings will be published in ALTEX. This workshop is funded by t4, the Transatlantic Think Tank for Toxicology, a collaboration of the toxicologically oriented chairs in Baltimore, Konstanz, and Utrecht sponsored by the Doerenkamp-Zbinden Foundation and the Evidence-based Toxicology Collaboration (EBTC) at Johns Hopkins University Bloomberg School of Public Health (USA).

EBTC comments in support of IRIS program (February 2018)
EBTC submitted written comments to a public workshop organised by the NAS Committee to Review Advances Made to the IRIS Process. We emphasised the value and benefit to us from our collaboration with the new IRIS leadership at EPA (Kris Thayer, Director of the EPA IRIS program is a member of the EBTC Board of Trustees) and the EPA's role as a leader among US agencies in adopting the systematic review as part of chemical risk assessment, with such work being key to modernising risk assessment and building trust with all stakeholders
EBTC colleagues contribute to new GRADE guidance for interpreting strength of evidence from preclinical animal studies (February 2018)
Although the framework is primarily intended for the field of preclinical animal studies, it is also highly relevant for the field of toxicology, since the two fields share many issues including e.g. how to take into account how well the results from animals translate to humans. A number of researchers involved with EBTC, including Kris Thayer, Holger Schünemann, Emily Sena and Rob de Vries contributed to its development. (See here for the publication.)
Director of US EPA IRIS programme brings top-tier expertise to EBTC (December 2017)

EBTC sponsors 4th International Symposium on Systematic Review and Meta-Analysis of Laboratory Animal Studies (ISSRMALAS) (September 2017)
This was another excellent conference in this series, with high-caliber speakers and EBTC staff presenting new research findings and sponsoring the poster session. Areas of particular interest in the EBT domain include the rise in interest in systematic mapping techniques as a precursor to systematic reviews, the growing importance of machine learning for dealing with the data volume problem in CRA.
