Humane Endpoint

Do, J. P., Defensor, E. B., Ichim, C. V. et al. 2020. Automated and continuous monitoring of animal welfare through digital alerting. Comparative Medicine 70(4), 313-327.

A primary goal in preclinical animal research is respectful and responsible care aimed toward minimizing stress and discomfort while enhancing collection of accurate and reproducible scientific data. Researchers use hands-on clinical observations and measurements as...

Zhang, X., Kumstel, S., Tang, G. et al. 2020. A rational approach of early humane endpoint determination in a murine model for cholestasis. ALTEX 37(2), 197-207.

Reduction of animal suffering during in vivo experiments is usually ensured by continuously monitoring the health status using a score sheet and by applying humane endpoints. However, most studies do not evaluate the plausibility of...

Helgers, S., Talbot, S. R., Riedesel, A. K. et al. 2020. Body weight algorithm predicts humane endpoint in an intracranial rat glioma model. Scientific Reports 10, 9020.

Humane endpoint determination is fundamental in animal experimentation. Despite commonly accepted endpoint criteria for intracranial tumour models (20% body weight loss and deteriorated clinical score) some animals still die before being euthanized in current research...

Wilkinson, M. J. A., Selman, C., McLaughlin, L. et al. 2020. Progressing the care, husbandry and management of ageing mice used in scientific studies. Laboratory Animals 54(3) 225–238.

Driven by the longer lifespans of humans, particularly in Westernised societies, and the need to know more about ‘healthy ageing’, ageing mice are being used increasingly in scientific research. Many departments and institutes involved with...

Nwagwu, C. D., Defensor, E., Jiang, M. Y. et al. 2020. Endpoint in ovarian cancer xenograft model predicted by nighttime motion metrics. Lab Animal 49(8), 227–232.

Despite several therapeutics showing promise in nonclinical studies, survival from ovarian cancer remains poor. New technologies are urgently needed to optimize the translation of nonclinical studies into clinical successes. While most nonclinical settings utilize subjective...

Percie du Sert, N., Rudd, J. A, Apfel, C. C. et al. 2011. Cisplatin-induce emesis: Systematic review and meta-analysis of the ferret model and the effects of 5-HT3 receptor antagonists. Cancer Chemotherapy and Pharmacology 67(3), 667-686.

Purpose: The ferret cisplatin emesis model has been used for ~30 years and enabled identification of clinically used anti-emetics. We provide an objective assessment of this model including efficacy of 5-HT3 receptor antagonists to assess...

Talbot, S. R., Biernot, S., Bleich, A. et al. 2020. Defining body-weight reduction as a humane endpoint: A critical appraisal. Laboratory Animals 54(1), 99–110.

In many animal experiments scientists and local authorities define a body-weight reduction of 20% or more as severe suffering and thereby as a potential parameter for humane endpoint decisions. In this study, we evaluated distinct...

Bertho, J.-M., Ancelet, S., Denais-Laliève, D. et al. 2020. Humane endpoints in severe irradiation experiments using non-human primates: A retrospective analysis. Scandinavian Journal of Laboratory Animal Science 46(1).

A retrospective statistical study has been performed in order to identify the biological, clinical and behavioural variables that could potentially predict the survival status of irradiated non-human primates (NHP) and to refine the future use...

National Research Council. 2009. Recognition and Alleviation of Pain in Laboratory Animals. The National Academies Press: Washington, DC, 198 pp.

Recognition and Alleviation of Pain in Laboratory Animals, the second of two reports revising the 1992 publication Recognition and Alleviation of Pain and Distress in Laboratory Animals from the Institute for Laboratory Animal Research (ILAR)...

Cowley, P. M., Roberts, C. R., Baker, A. J. 2019. Monitoring the health status of mice with bleomycin-induced lung injury by using body condition scoring. Comparative Medicine 69(2), 95–102.

Well-defined, humane endpoints aid in monitoring animal health status during disease development. Body condition scoring (BCS) is a method for assessing health status in mouse studies where wasting and death are potential endpoints. Whether BCS...
