By characterizing owner profiles, the research seeks to enhance veterinary approaches and education to better address the unique challenges and emotional aspects associated with pet care and loss. An anonymous online survey was distributed to 302 French owners who already experienced the loss of an animal, including demographic information and feelings about their experience of a pet's end-of-life (EOL). Data were analysed using descriptive and qualitative analysis (including the use of AI chatbot ChatGPT). 56.6 % of participants reported a relatively smooth pet death, yet 67.0 % found the end-of-life period challenging. Three distinct owner groups emerged, each with varying needs. The first group expressed high guilt and a greater need for support, emphasizing the necessity for information and improved training. The second group, more informed and independent, benefits from veterinary support, while a leaflet suits them. The third group, competent in pain evaluation, requires less veterinary support. These differences highlight the importance of personalized owner support. The study proposes essential pillars for veterinarians and nurses' training, forming the EPITO system: Emotional support, Personalization, Information, Training, Tools, and Open discussion.</div></div>","PeriodicalId":23144,"journal":{"name":"Topics in companion animal medicine","volume":"65 ","pages":"Article 100960"},"PeriodicalIF":1.3,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143372718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Human data suggest that monorchid patients have lower serum anti-Müllerian hormone (AMH) levels when compared to cryptorchids, premises that has been also scrutinized in veterinary medicine. Here, we describe a case of monorchidism in a tomcat, focusing on the clinical findings and the dynamics of AMH serum levels before and after the removal of the singularly identified testicle. To contribute to the limited knowledge of AMH levels across different reproductive statuses in tomcats, the findings from this monorchid case were compared to values obtained from two cryptorchid tomcats (one unilateral and one bilateral), three intact tomcats, and three castrated tomcats. In addition, clinical, histopathological and ultrasound examinations were conducted in all tomcats. The AMH levels in the monorchid tomcat revealed a consistent decrease after surgery, from 27.3 ± 0.2 ng/ml when the testicle was still present, to 2.3 ± 0.2 ng/ml 1 week later, and further decreasing below the detection limit (&lt;0.15 ng/ml) for the last 2 weeks of the trial, matching the AMH level of the castrated male. AMH serum levels of the bilateral and unilateral cryptorchid tomcat (22.5 ± 0.3 ng/ml; 24.1 ± 0.2 ng/ml) were in agreement with those of the three intact males (19.1 ± 2.2 ng/ml) and the monorchid prior to surgery. AMH testing effectively confirmed the absence of testicular tissue after unilateral orchiectomy in a monorchid tomcat but did not differentiate between monorchidism and cryptorchidism.

Rapid and accurate diagnosis of neoplasia often leads to a better disease outcome. Cytology is an inexpensive and minimally invasive method frequently used to diagnose neoplasia. However, the physical distance between veterinary practices and pathologists often impedes rapid diagnosis. Telecytology facilitates rapid interpretation of cytology results leading to prompt diagnosis. Smartphone cameras have been suggested as an alternative to image-capturing devices used in conventional telecytology. This project was designed to evaluate whether telecytology with smartphone cameras can be effectively used to diagnose canine round cell neoplasms. For this purpose, five round cell tumours [lymphoma, mast cell tumour (MCT), transmissible venereal tumour (TVT), plasmacytoma and histiocytoma] were imaged using a smartphone camera and the images were sent to two pathologists at distant locations via emails. For each tumour type, the cytopathological diagnosis from the two pathologists was compared with the histopathological diagnosis of the same tumour and the agreement was determined by Cohen's kappa test. Inter-pathologist variability was also determined using the same test. The diagnostic agreement between histopathology and cytopathology was excellent (κ = 1.0) for lymphoma and MCT when x10 objective images were used. Variable agreements were reported for TVT, plasmacytoma and histiocytoma. When both 10x and 40x objective images were used, diagnostic agreement between histopathology and cytopathology was excellent for all tumours except histiocytoma. The inter-pathologist agreement was excellent for lymphoma, MCT and TVT using the 10x objective, while with the 40x objective it was excellent for all tumours except histiocytoma. The diagnostic accuracy was greater when both 10x and 40x objective images were used for diagnosis than when only 10x objective images were used (χ2 = 40.0, p = &lt; 0.001). The use of images obtained using 10x and 40x objectives increased the diagnostic accuracy compared to the use of only 10x objective. These findings suggest that telecytology performed with smartphone cameras is a promising method to rapidly diagnose canine round cell tumours. Future studies with larger number of samples and samples with atypical presentations of round cell neoplasms will be helpful to further elaborate the present findings.</div></div>","PeriodicalId":23144,"journal":{"name":"Topics in companion animal medicine","volume":"64 ","pages":"Article 100946"},"PeriodicalIF":1.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142866947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
