However, the effective implementation of pain management depends on the knowledge and attitudes of the personnel involved. Following a Federation of European Laboratory Animal Science Associations 'Pain in Mice' working group initiative, a questionnaire to survey current practices concerning analgesic use in laboratory mice was distributed to several professional groups in the field of laboratory animal science. Besides demographic data, attitudes to pain and analgesia and sources of information and advice on pain management were assessed. Data were gathered and analysed through an e-survey provider. Most respondents (N = 222) were from Europe (90%). Analgesics were administered to murine surgical models by 92% of respondents in most cases and by 66% to all mice undergoing surgery. Most respondents used multimodal analgesic regimens (69%). For non-surgical models, 34% of respondents provided analgesics. The most commonly administered classes of analgesics were opioids (mostly buprenorphine) and non-steroidal anti-inflammatory drugs (mostly meloxicam and carprofen). A wide range of dose rates of meloxicam and carprofen was reported. Local anaesthetics were also widely used in surgical models (mostly lidocaine). Pain assessment was undertaken by most respondents (98%). In conclusion, most respondents provided analgesics to mice undergoing surgery and used analgesics in some non-surgical models. A considerable variation in the dose range used and the timing of administration of analgesics likely reflects both a lack of data and variation in pain assessment methodologies.","PeriodicalId":18013,"journal":{"name":"Laboratory Animals","volume":" ","pages":"396-412"},"PeriodicalIF":1.3,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12120196/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143059820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The global diabetic population is expected to double by 2025, from 380 million, posing a significant health challenge. Most diabetic individuals fall into the type 1 or type 2 categories, and diabetes adversely affects various organs, such as the kidneys, liver, nervous system, reproductive system, and eyes.This review focuses on animal models of diabetes induced by chemical agents, which are essential tools for understanding disease mechanisms, investigating complications, and testing antidiabetic drugs. Models include those caused by streptozotocin (STZ), alloxan, ferric nitrilotriacetate (Fe-NTA), dithizone, and anti-insulin serum.Streptozotocin (STZ)-induced diabetes models create type 1 and 2 diabetes by destroying pancreatic beta cells. The combination of STZ with nicotinamide mimics type 2 diabetes phenotypes. Alloxan induces a hyperglycemic state by causing free radical formation that selectively destroys pancreatic beta cells. Fe-NTA and dithizone also create diabetes models by damaging pancreatic beta cells. Anti-insulin serum models induce insulin resistance and hyperglycemia by generating antibodies against insulin receptors, leading to a condition similar to type 1 diabetes.Each model has unique characteristics that make it suitable for different aspects of diabetes research. These models are used to understand the pathogenesis of diabetes, develop new treatment strategies, and evaluate the efficacy of potential drugs.","PeriodicalId":18013,"journal":{"name":"Laboratory Animals","volume":" ","pages":"356-363"},"PeriodicalIF":1.3,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143007861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In laboratory animal facilities it is used prophylactically or therapeutically to maintain the health status of the colony or experimentally in studies. Although ivermectin is generally safe to use, there are reports of neurotoxicity associated with ivermectin crossing the blood-brain barrier due to overdosing or blood-brain barrier dysfunction. In mice, P-glycoprotein maintains the blood-brain barrier and mice with a mutation in the P-glycoprotein encoding gene mdr1a are 50-100 times more sensitive to ivermectin. Signs of neurotoxicity include ataxia, bradypnea, recumbency, tremor, and death. We report neurotoxicity after ivermectin administration was used for the purpose of eradicating the murine-specific intestinal nematode Heligmosomoides polygyrus in C57BL/6NTac and C57BL/6NCrl mice. The mice were dewormed by subcutaneous administration of 10 or 20 mg/kg ivermectin to eradicate all stages of Heligmosomoides polygyrus. At 24-48h after deworming, 5% (n = 4) of the mice presented with tremor, ataxia, and/or head tilt. The affected mice were euthanised and gross pathological findings were found in one of the four mice (left-sided hydronephrosis). We assume that the observed neurological effects were due to defects in the blood-brain barrier, overdosing or individual sensitivity. This report provides a reason for caution when deworming laboratory mice subcutaneously with ivermectin at doses of 10 mg/kg or higher.","PeriodicalId":18013,"journal":{"name":"Laboratory Animals","volume":" ","pages":"374-383"},"PeriodicalIF":1.3,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12120199/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142882198","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These pressures are often due to the need to balance scientific objectives, ethical responsibilities, and personal emotions, while trying to maintain legal and institutional animal housing and care standards. When these profession-related pressures are exacerbated by toxic social relationships and financial challenges, it may lead to chronic stress that will ultimately cause compassion fatigue. This review aimed to analyse publication trends on compassion fatigue among laboratory animal personnel by undertaking a bibliometric analysis of published articles to produce insights that could inform future research strategies. A literature search was carried out via the Scopus databases for articles published in English. The data collected from the search was transferred to the Bibliometrix R-package and assessed for publication trends, analysis of contributing countries, thematic evolution, and the co-occurrence of authors' keywords. Seventeen articles published between 2015 and 2024 were retrieved for analysis. Among these, 14 were survey studies and 3 were literature reviews. The number of articles published is on an upward trend, with all authors being affiliated with Global North institutions. The keyword analysis identified 53 words. The most common term used was 'compassion fatigue' (CF) and the analysis indicated that technicians and veterinarians are the primary target populations for CF research. The modest rise in the body of literature on CF and mental health issues among laboratory animal personnel is commendable and I encourage more work to be done to better understand this complex phenomenon.","PeriodicalId":18013,"journal":{"name":"Laboratory Animals","volume":" ","pages":"236772251332567"},"PeriodicalIF":1.3,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144187312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
