Topic Information

Dear Colleagues,

Effective application of the principles of the 3Rs is critical to the successful use of research animals. Studies should be conducted in as refined a manner as possible while reducing the required numbers as much as possible, or Replacing animal use either entirely or partially, such as by using species that are believed either to be non-sentient or to have low sentience capacity. The importance of this topic cannot be overemphasized, as applying the 3Rs provides the principal framework by which research and testing is conducted in an ethically sound manner. Indeed, their application is able to provide high-quality, potentially more reproducible data due to the avoidance of unnecessary suffering. Submissions from any research discipline are invited. Researchers may use any species in which either positive or negative findings further knowledge on refinement, on how to Reduce animal numbers using statistical methods or improved study designs, and ultimately, on how to Replace the use of animals in scientific testing and research. Submissions describing studies using new and/or advanced non-invasive procedures are particularly welcome.

Stepwise Imperatives for Improving the Protection of Animals in Research and Education in Canada

In this paper, we review the standard-setting tools of different levels of government in Canada for overseeing the care of animals used in science against a landscape of other international efforts. We find regulatory inconsistencies, argue that the related shortcomings are detrimental to the level of care afforded to animals, and offer suggestions for a centralized and proactive approach that could close the existing gaps. Given the resources, cost, and time it would take to transform the current system into a single cohesive one, the proposed approach is a stepwise one, and begins with the addition of two new Rs—Reflection and Responsiveness—to the existing 3Rs framework: Replacement, Refinement, and Reduction. Reflection emphasizes more continuous and specific attention to progress in the research pathway as it applies to animals than is currently required by institutional review and reporting; Responsiveness speaks to the immediate action that researchers can take responsively to that ongoing evaluation.

Animal Research Regulation: Improving Decision-Making and Adopting a Transparent System to Address Concerns around Approval Rate of Experiments

The use of nonhuman animals in biomedical research is regulated under stringent conditions, not only in response to societal attitudes towards animal experimentation but also because ethical responsibility in scientific research requires researchers and veterinarians to be more invested and aim to improve the welfare of animals used for experiments. Analyses of animal research oversight reveal the frequent approval of experiments, and the approval of some experiments has raised and continues to raise public concerns. Societal compliance is required for a consensus-based approach to animal research policy, prompting the need to have transparent discussions about oversight and the frequency of approvals. We discuss how frequent approval may be perceived and why it seems problematic from a societal perspective: the regulatory process exists to approve only legitimate experiments. Although some experiments remain unacceptable irrespective of their harm–benefit ratios, almost all experiments are approved. We explain some possible legitimate reasons for frequent approval and how the review process could be leading to the approval of illegitimate studies. To ensure transparency and improve public trust and understanding of oversight, we propose the adoption of a platform to inform society about how unethical experiments are screened out. Full article

The 3Rs aim to refine animal welfare, reduce animal numbers, and replace animal experiments. Investigations disclose that researchers are positive towards 3Rs recommendations from peers. Communication of 3Rs approaches via primary preclinical animal experimental literature may become a fast-forward extension to learn relevant 3Rs approaches if such are reported. This study investigates 3Rs-reporting in peer-reviewed preclinical animal research with at least one author affiliated to a Danish university. Using a systematic search and random sampling, we included 500 studies from 2009 and 2018. Reporting was low and improvement over time limited. A word search for 3R retrieved zero results in 2009 and 3.2% in 2018. Reporting on 3Rs-related sentences increased from 6.4% in 2009 to 18.4% in 2018, “reduction” increased from 2.4% to 8.0%, and “refinement” from 5.2% to 14.4%. Replacement was not reported. Reporting of the methodology was missing. For “reduction”, methodology was mentioned in one study in 2009 and 11 studies in 2018, and for “refinement” in 9 and 21, respectively. Twenty-one studies stated compliance with ARRIVE-guidelines or similar without disclosure of details. Reporting of 3Rs approaches in preclinical publications is currently insufficient to guide researchers. Other strategies, e.g., education, interdisciplinary collaboration, and 3Rs funding initiatives, are needed. Full article
