Abstract: O presente estudo teve como objetivo avaliar o efeito anti-inflamatório do dimetilsulfóxido (DMSO) em cadelas diagnosticadas com neoplasia mamária e submetidas à mastectomia unilateral associada com a ovariohisterectomia pelo acesso abdominal lateral (flanco). Foram utilizadas 20 cadelas de raça e massa corpórea variadas, e diagnosticadas com neoplasia mamária pelo exame citopatológico. Todos os animais foram submetidos à mastectomia unilateral e o DMSO, na dose de 1 g/kg, foi administrado por via intravenosa, 15 minutos antes do término do procedimento cirúrgico (15PRE), 24 (24hPOS) e 48 horas após o procedimento cirúrgico (48hPOS). As variáveis avaliadas incluíram a frequência respiratória, frequência cardíaca, temperatura corpórea, eritrograma, leucograma, bioquímica sanguínea sérica, aspecto macroscópico da ferida cirúrgica e efeitos colaterais do DMSO. Os parâmetros clínicos não apresentaram diferenças significativas entre os momentos avaliados. Os valores da temperatura corporal apresentaram um aumento significativo entre 15PRE e 24hPOS, 15PRE e 48hPOS. Os valores dos eritrócitos, hemoglobina, plaquetas, proteína sérica total e alanina aminotransferase apresentaram variações significativas ao longo dos momentos avaliados, porém permaneceram no padrão fisiológico da espécie. De acordo com os resultados, concluiu-se que o DMSO possui uma ação anti-inflamatória em cadelas submetidas à mastectomia unilateral associada com a ovariohisterectomia pelo acesso abdominal lateral (flanco), e seguro quando administrado na dose de 1 g/kg por via intravenosa durante três dias.

Abstract: Pain assessment guides decision-making in pain management and improves animal welfare. We aimed to investigate the reliability and validity of the UNESP-Botucatu cattle pain scale (UCAPS) and the cow pain scale (CPS) for postoperative pain assessment in Bos taurus (Angus) and Bos indicus (Nelore) bulls after castration. Methods: Ten Nelore and nine Angus bulls were anaesthetised with xylazine–ketamine–diazepam–isoflurane–flunixin meglumine. Three-minute videos were recorded at -48 h, preoperative, after surgery, after rescue analgesia and at 24 h. Two evaluators assessed 95 randomised videos twice one month apart. Results: There were no significant differences in the pain scores between breeds. Intra and inter-rater reliability varied from good ( .70) to very good ( .81) for all scales. The criterion validity showed a strong correlation (0.76–0.78) between the numerical rating scale and VAS versus UCAPS and CPS, and between UCAPS and CPS (0.76). The UCAPS and CPS were responsive all items and total scores increased after surgery. Both scales were specific (81–85%) and sensitive (82–87%). The cut-off point for rescue analgesia was for UCAPS and for CPS. Conclusions. The UCAPS and CPS are valid and reliable to assess postoperative pain in Bos taurus and Bos indicus bulls.

Abstract: In humans, hospitalisation, disease type, and environmental factors evidently affect the quality of sleep, further influencing patient recovery. The objective of the present study was to report the resting and lying behaviour of hospitalised horses, and whether lying behaviours differ depending on the physiological severity of joint damage. We hypothesised that the resting and lying behaviour can change during the hospitalisation and physiological severity of joint damage affect the time of rest in horses. A descriptive observational study was performed to evaluate the effect of hospitalisation on the recumbency time of 8 adult horses with different degrees of osteoarthritis of the metacarpophalangeal joint. The horses' rest time was monitored using cameras during the first 5 days of hospitalisation. The total time of lateral recumbency and frequency of recumbency were greater after the 4

Abstract: Horse racing is a major sport practiced worldwide. The environment to which horses are exposed during race meetings can influence their behavior. However, to the best of our knowledge, a method for assessing a horse’s response to its surroundings during the pre- and post-race periods has not yet been reported. This study aimed to create a standard list of descriptors for use in a qualitative behavioral assessment (QBA) focused on assessing the emotional expressivity of horses before and after racing events. Seventy pre- or post-race 30-second videos of horses were randomly selected from our database of 700 videos. A panel of 8 experienced equine sports medicine specialist veterinarians watched a 60 min presentation on QBA. The panel then watched all videos randomly, simultaneously, in idually, continuously, and without any verbal interaction, describing the descriptors related to the emotional expressivity of the horse after each video using a method known as free-choice profiling (FCP). The initial selection of descriptors was based on those indicated by more than one evaluator in the same video, or descriptors with more than 20 occurrences. The second selection was performed based on the content validity index (CVR) to select the descriptors retained in the previous step. Another panel of six veterinarians scored each of the descriptors retained for content validity on a visual scale. Interobserver reliability was estimated using the intraclass correlation coefficient (ICC) and its respective 95% confidence intervals (CI). A natural language processing (NLP) algorithm was used to analyze the behavior (positive or negative polarity) of the descriptors based on the lexicoPT package of R software. NLP analysis considered the descriptors “agitated,” “troubled,” “restless” and “irritated” to have a negative polarity, while “focused,” “relaxed” and “peaceful” had a positive polarity. In the principal component analysis (PCA), descriptors in a negative state were associated with each other and inversely associated with descriptors in a positive state. We conclude with a fixed list of descriptors to be used in a QBA to assess emotional and welfare expressivity in racehorses’ pre- and post-race environments.

Abstract: We aimed to develop and validate the Unesp-Botucatu goat acute pain scale (UGAPS). Thirty goats (5 negative controls and 25 submitted to orchiectomy) were filmed for 7 min at the time points 24 h before and 2 h, 3 h (1 h after analgesia), and 24 h after orchiectomy. After content validation, according to an ethogram and literature, four blind observers analyzed the videos randomly to score the UGAPS, repeating the same assessment in 30 days. According to the confirmatory factor analysis, the UGAPS is unidimensional. Intra- and interobserver reliability was very good for all raters (Intraclass correlation coefficient ≥85%). Spearman’s correlation between UGAPS versus VAS was 0.85 confirming the criterion validity. Internal consistency was 0.60 for Cronbach’s α Cronbach and 0.67 for McDonald’s ω. The item-total correlation was acceptable for 80% of the items (0.3–0.7). Specificity and sensitivity based on the cut-off point were 99% and 90%, respectively. The scale was responsive and demonstrated construct validity shown by the increase and decrease of scores after surgery pain and analgesia, respectively. The cut-off point for rescue analgesia is ≥3 of 10, with an area under the curve of 95.27%. The UGAPS presents content, criterion, and construct validities, responsiveness, and reliability to assess postoperative pain in castrated goats.
