Cognitive Dissonance in Laboratory Animal Medicine and Implications for Animal Welfare

The culture of care to enhance laboratory animal personnel well-being: a scoping review

There has been intense focus on improving the quality of animal research in recent times. An emerging concept of a 'culture of care' has been proposed as another important pillar to enhance scientific quality, with staff well-being being a critical aspect. Professionals working with research animals can face moral and psychological burdens and are at risk of experiencing work-related stress. However, data on the global prevalence of stress in this population is limited. Equally, it is not clear how these stresses manifest, and what impact they might have on an individual's workplace performance and research quality. The purpose of this review was to identify work-related stress, its prevalence, and map evidence on strategies to mitigate stresses. We also set out to identify studies assessing the association between work-related stress and research quality. A systematic search was conducted across four databases, in addition to hand searching relevant references. We included peer-reviewed publications describing work-related stress, culture of care and laboratory animal professionals. A total of 49 publications were included for data mapping. Compassion fatigue was the most frequently described work-related stress, and its prevalence across Europe and North America is likely to be widespread. Multiple strategies to mitigate compassion fatigue and work-related stress were put forward, however, limited empirical evidence was available to assess success. Moreover, no studies reported empirical data linking work-related stress with research quality, despite several publications stating the case. Further population-specific research and measured assessments are urgently needed to deliver culture of care programmes to improve human well-being, animal welfare and research quality.

The Elephant in the Room: Recognition and Documentation of Personnel Practices That Confound Reproducibility

The ability to apply findings from animal studies efficiently and effectively is predicated on an understanding of biology and pathobiology, how that biology relates to the human systems being modeled, and how the studies are conducted and reported. This overview discusses various factors in research within the animal environment (referred to as extrinsic factors) that the NIH now expects to be documented to foster replicability in science and expand interpretations of study outcomes. Specifically, an important extrinsic factor in research with animals is that of individual personnel who perform handling practices, participate in research interactions, and share an overall presence in the housing facility with animals, all of which can confound reproducibility efforts in biomedical science. An improved understanding of the influences and behaviors of animal research personnel on animal responses is critical with regard to research results and the interpretation of data collected from animal models of biomedical disease.

Professional quality of life in animal research personnel is linked to retention & job satisfaction: A mixed-methods cross-sectional survey on compassion fatigue in the USA

BACKGROUND

Working with research animals can be both rewarding and challenging. The rewarding part of the work is associated with understanding the necessity for animal research to improve the health of humans and animals and the knowledge that one can provide care and compassion for the animals. Challenges with animal research include witnessing stress/pain in animals necessitated by scientific requirements, end of study euthanasia, and societal stigmatization about animal research. These challenges could be compounded with more general workplace stresses, in turn, impacting job retention and satisfaction. However, these factors have yet to be formally evaluated. Therefore, the purpose of this survey was to comprehensively evaluate professional quality of life's correlation with key workplace metrics.

METHODS

Six institutions were recruited to participate in a longitudinal intervention trial on compassion fatigue resiliency. This manuscript reports key baseline metrics from this survey. A cross-sectional mixed methods survey was developed to evaluate professional quality of life, job satisfaction, retention, and factors influencing compassion fatigue resiliency. Quantitative data were analyzed via general linear models and qualitative data were analyzed by theme.

RESULTS

Baseline data was collected from 198 participants. Personnel who reported higher compassion satisfaction also reported higher retention and job satisfaction. Conversely, personnel who reported higher burnout also reported lower job satisfaction. In response to open-ended questions, participants said their compassion fatigue was impacted by institutional culture (70% of participants), animal research (58%), general mental health (41%), and specific compassion fatigue support (24%).

CONCLUSIONS

In conclusion, these results show that professional quality of life is related to important operational metrics of job satisfaction and retention. Furthermore, compassion fatigue is impacted by factors beyond working with research animals, including institutional culture and general mental health support. Overall, this project provides rationale and insight for institutional support of compassion fatigue resiliency.

The Potential Relationship Between a Cognitive Dissonance State and Musculoskeletal Injury: A Systematic Review

OBJECTIVE

The objective of this systematic review was to investigate the potential link between cognitive dissonance or its related constructs (emotional dissonance, emotional labor) and musculoskeletal disorders.

BACKGROUND

The etiology of musculoskeletal disorders is complex, as pain arises from complex interactions among physical, social, and psychological stressors. It is possible that the psychological factor of cognitive dissonance may contribute to the etiology and/or maintenance of musculoskeletal disorders.

METHOD

MEDLINE, APA PsycInfo, and CINAHL Plus databases were searched for studies investigating cognitive dissonance or its related constructs as exposure(s) of interest and outcomes related to physical health (including, but not limited to, musculoskeletal pain). Risk of bias was assessed using the Appraisal tool for Cross-Sectional Studies (AXIS) tool.

RESULTS

The literature search yielded 7 studies eligible for inclusion. None of the included studies investigated cognitive dissonance directly but instead investigated dissonance-related constructs of emotional dissonance and emotional labor, in which a mismatch between required and felt emotions might elicit a psychological response consistent with the cognitive dissonance state. Moderate effect sizes between dissonance-related constructs and musculoskeletal disorders were noted (OR 1.25-2.22).

CONCLUSION

There is likely a relationship between the two factors studied. However, as the included studies were cross-sectional in nature, a causal relationship between cognitive dissonance-related constructs and musculoskeletal disorders cannot be inferred. Therefore, future study proposing and validating a causal pathway between these variables is warranted.

APPLICATION

Cognitive dissonance and its related constructs may serve as risk factors for musculoskeletal disorders that have not been considered previously.

Psychological stress and strain in laboratory animal professionals - a systematic review

Laboratory animal professionals (LAP) are faced with various situations and tasks influencing their mental well-being. A systematic review has been conducted to investigate whether there are specific stressors for LAP and which moderators are relevant for the development of psychological strain. A comprehensive search following PRISMA Guidelines was carried out in June 2021. Results include 12 studies and have been summarized qualitatively in narrative synthesis and tabular presentation. Available literature indicates that LAP are facing stressors but does not allow for conclusions on specific stressful job duties other than euthanasia.Signs of strain are present in LAP. Specifically, participants in qualitative studies reported acute symptoms, while chronic manifestations were in focus in quantitative studies. Although a wide variety of moderating factors have been investigated, only social support has been rated as relevant by multiple qualitative and quantitative studies without contrasting results.According to current data, there is a risk for psychological strain in LAP. However, there is limited understanding of specific stressors and data on moderators is diverse. Further studies that focus on domain-specific knowledge and clearly distinguish stressors from moderators are necessary to set up institutional programmes addressing psychological strain in LAP.

Compassion Fatigue and Coping Mechanisms of Laboratory Animal Professionals from Europe, China, and Japan

Laboratory animal professionals (LAP) may experience situations that contribute to compassion fatigue (CF). The goal of this research was to better understand CF in LAP in and across employment categories. Surveys were distributed through LAP organizational listservs in the European Union (EU), China, and Japan, and results were analyzed to identify CF prevalence, personal and work-related factors, coping mechanisms, and beneficial work-support programs. Independent χ²-tests compared personal and work-related factors and feelings of CF. Feelings of CF and coping mechanisms were compared with personality scores using independent sample t tests. There were 302 respondents from the EU, 39 from China, and 77 from Japan. Over half of respondents from the EU (52%) and China (56%) reported experiencing CF (52%), with fewer (32%) reporting CF in Japan. No major differences were found based on employer type. Personality scores were significantly related to feelings of CF and preferred coping mechanisms. Work-related factors that contributed to feelings of CF in over half of respondents included staffing levels, workplace relationships, and availability of programs geared to address CF. Across regions, talking to someone, physical activity, getting away from work, and self-care were effective coping mechanisms in over 50% of respondents. Fewer than 30% of respondents indicated that their place of employment had CF support programs, and even fewer (8% to 28%) indicated that these programs were helpful. The study results suggest that to be effective, employer CF programs for LAP should consider providing quiet places at work and programs for self-care, promoting physical and mental health and social support systems, and establishing opportunities to memorialize animals.

Exploring Music Therapists' Experiences With and Perceptions About Copyrighted Music: A Thematic Analysis

Patient-preferred music is often copyrighted music; prior research, however, has paid scant attention to music therapists' understanding and use of copyrighted music. To fill a gap in the literature, this exploratory study sought to understand music therapists' experiences and perceptions about permissible therapeutic uses of copyrighted music. Semi-structured interviews were conducted with 18 board-certified music therapists working in the United States. Collectively, these participants had over 300 years of professional experience. The interview transcripts were analyzed using an inductive approach to thematic analysis. Five main themes were identified: (1) copyright concerns created a complex psychological burden; (2) therapeutic needs warranted use of copyrighted music; (3) perceptions varied on permissible therapeutic practices using copyrighted music; (4) varied sources informed an understanding of copyright law; and (5) copyright clarity was needed to reduce the psychological burden. These themes suggest that psychological stress was produced by copyright uncertainty coupled with attempts by participants to satisfy diverse interests and protect multiple stakeholders, including patients, employers, their profession, and the law. Our findings suggest that a lack of clarity about permissible uses of copyrighted music can complicate music therapists' decision-making about appropriate therapeutic interventions. Clarity on permissible therapeutic uses of music could yield benefits for music therapists, patients, and the community.

Animal researchers shoulder a psychological burden that animal ethics committees ought to address

Animal ethics committees (AECs) typically focus on the welfare of animals used in experiments, neglecting the potential welfare impact of that animal use on the animal laboratory personnel. Some of this work, particularly the killing of animals, can impose significant psychological burdens that can diminish the well-being of laboratory animal personnel, as well as their capacity to care for animals. We propose that AECs, which regulate animal research in part on the basis of reducing harm, can and ought to require that these harms to researchers are reduced as well. The paper starts by presenting evidence of these burdens and their harm, giving some examples showing how they may be mitigated. We then argue that AECs are well placed to account for these harms to personnel and ought to use their power to reduce their occurrence. We conclude by responding to four potential objections: (1) that this problem should be addressed through health and safety administration, not research ethics administration; (2) that the proposal is unjustifiably paternalistic; (3) that these harms to laboratory animal personnel ought to occur, given their treatment of animals; and (4) that mitigating them may lead to worse treatment of research animals.

Environmental Enrichment for Rats and Mice Housed in Laboratories: A Metareview

Simple Summary

Environmental enrichment has been widely studied with laboratory rodents, but there is no consensus regarding what counts as enrichment or what it should achieve. Inconsistent use of the term “enrichment” creates challenges in drawing conclusions about the quality of an environment. We conducted a metareview to better understand the definitions and goals of enrichment, perceived risks or requirements of enrichment, and what forms of enrichment have previously been endorsed for use with rodents housed in laboratories. This may help researchers and animal care staff to better define their chosen approach and intended outcomes when providing environmental enrichment.

Abstract

Environmental enrichment has been widely studied in rodents, but there is no consensus on what enrichment should look like or what it should achieve. Inconsistent use of the term “enrichment” creates challenges in drawing conclusions about the quality of an environment, which may slow housing improvements for laboratory animals. Many review articles have addressed environmental enrichment for laboratory rats and mice (Rattus norvegicus and Mus musculus). We conducted a metareview of 29 review articles to assess how enrichment has been defined and what are commonly described as its goals or requirements. Recommendations from each article were summarised to illustrate the conditions generally considered suitable for laboratory rodents. While there is no consensus on alternative terminology, many articles acknowledged that the blanket use of the terms “enriched” and “enrichment” should be avoided. Environmental enrichment was most often conceptualised as a method to increase natural behaviour and improve animal welfare. Authors also commonly outlined perceived risks and requirements of environmental enrichment. We discuss these perceptions, make suggestions for future research, and advocate for the adoption of more specific and value-neutral terminology.

FDI-6 and olaparib synergistically inhibit the growth of pancreatic cancer by repressing BUB1, BRCA1 and CDC25A signaling pathways

Inducing homologous recombination (HR) deficiency is a promising strategy to broaden the indication of PARP1/2 inhibitors in pancreatic cancer treatment. In addition to inhibition kinases, repression of the transcriptional function of FOXM1 has been reported to inhibit HR-mediated DNA repair. We found that FOXM1 inhibitor FDI-6 and PARP1/2 inhibitor Olaparib synergistically inhibited the malignant growth of pancreatic cancer cells in vitro and in vivo. The results of bioinformatic analysis and mechanistic study showed that FOXM1 directly interacted with PARP1. Olaparib induced the feedback overexpression of PARP1/2, FOXM1, CDC25A, CCND1, CDK1, CCNA2, CCNB1, CDC25B, BRCA1/2 and Rad51 to promote the acceleration of cell mitosis and recovery of DNA repair, which caused the generation of adaptive resistance. FDI-6 reversed Olaparib-induced adaptive resistance and inhibited cell cycle progression and DNA damage repair by repressing the expression of FOXM1, PARP1/2, BUB1, CDC25A, BRCA1 and other genes-involved in cell cycle control and DNA damage repair. We believe that targeting FOXM1 and PARP1/2 is a promising combination therapy for pancreatic cancer without HR deficiency.

Compassion Fatigue in Laboratory Animal Personnel during the COVID-19 Pandemic

Compassion Fatigue (CF) is commonly observed in professions associated with human and animal care. The COVID-19 pandemic compelled laboratory animal research institutions to implement new work practices in order to maintain essential animal care operations. These modifications ranged from shift changes to last-resort measures, such as culling animal colonies, to accommodate reduced staffing. Such changes could cause personnel to experience increased stress, isolation, and helplessness-all of which can increase CF risk. In the current study, 200 persons involved with animal research completed an online survey to gauge whether CF among laboratory animal personnel had increased during the pandemic. The survey examined professional quality of life, self-assessed levels of CF, institutional changes, perceived changes in animal welfare, and institutional measures intended to alleviate CF. A total of 86% of participants had experienced CF at some point in their career, with 41% experiencing a CF event (new or worsening symptoms of CF) during the pandemic. In addition, 90% of participants who reported a CF event also reported subsequent effects on their personal or professional lives. Health, employment, and animal-related stress that arose due to the pandemic were all found to influence CF scores significantly. Although 96% of respondents were considered essential workers, 67% did not feel as valued for their work as other essential personnel. Furthermore, 88% of personnel responsible for the euthanasia of healthy animals who experienced a CF event reported that CF also affected their personal life, professional life, or both, and 78% responded that interventions from internal CF programs or leadership did not help to alleviate symptoms of CF. The COVID-19 pandemic and resultant institutional changes will likely have lasting effects on persons and organizations. By determining and subsequently mitigating sources of CF, we can better assist the laboratory animal community during future crises.
