    Para testar a hipĂłtese de que ocorre elevação nas concentraçÔes de biomarcadores do estresse nas corridas na vaquejada e nas prĂĄticas veterinĂĄrias nas fazendas com bovinos, foi desenvolvido um experimento para avaliar as concentraçÔes da creatinaquinase (CK) e do cortisol (CORT) em bovinos submetidos a esses desafios. Para tal, foram utilizados 160 bovinos, divididos em quatro grupos e submetidos ao mesmo manejo: vaquejada com desequilĂ­brio (G-Vq, n=40); vaquejada sem desequilĂ­brio (G-VqC, n=40); bovinos vacinação (G-Vac, n=40), e bovinos controle positivo vacinação (G-VacC, n=40). Amostras de sangue venoso foram colhidas em tubos Ă  vĂĄcuo, sem anticoagulantes, em trĂȘs momentos: prĂ©-desafio (M-0), imediatamente apĂłs o desafio (M-1) e apĂłs 4 horas do desafio (M-2). Utilizou-se ANOVA e teste de Tukey para avaliar os resultados com p<0,05. Os resultados indicaram variaçÔes nas concentraçÔes CK (p<0,01) e cortisol (p<0,01) entre os grupos, com interação entre os grupos e os momentos (p<0,01). Nas condiçÔes atuais, pode-se concluir que as prĂĄticas de manejo adotadas, corrida de vaquejada e vacinação, promovem elevaçÔes na CK e cortisol. Mas apĂłs 4 horas da aplicação do desafio, as concentraçÔes dos biomarcadores retornaram ao nĂ­vel do prĂ©-desafio, com a exceção na concentração da CK no G-Vac. Assim, observou-se que esses biomarcadores, podem ser utilizados para avaliação de estresse em bovinos, quando avaliados prĂ©, imediatamente apĂłs e apĂłs 4 horas do estĂ­mulo do estressor e os atuais resultados contribuem para verificação do bem-estar animal nas prĂĄticas de manejo estudadas

    Background Anastomotic leak affects 8 per cent of patients after right colectomy with a 10-fold increased risk of postoperative death. The EAGLE study aimed to develop and test whether an international, standardized quality improvement intervention could reduce anastomotic leaks. Methods The internationally intended protocol, iteratively co-developed by a multistage Delphi process, comprised an online educational module introducing risk stratification, an intraoperative checklist, and harmonized surgical techniques. Clusters (hospital teams) were randomized to one of three arms with varied sequences of intervention/data collection by a derived stepped-wedge batch design (at least 18 hospital teams per batch). Patients were blinded to the study allocation. Low- and middle-income country enrolment was encouraged. The primary outcome (assessed by intention to treat) was anastomotic leak rate, and subgroup analyses by module completion (at least 80 per cent of surgeons, high engagement; less than 50 per cent, low engagement) were preplanned. Results A total 355 hospital teams registered, with 332 from 64 countries (39.2 per cent low and middle income) included in the final analysis. The online modules were completed by half of the surgeons (2143 of 4411). The primary analysis included 3039 of the 3268 patients recruited (206 patients had no anastomosis and 23 were lost to follow-up), with anastomotic leaks arising before and after the intervention in 10.1 and 9.6 per cent respectively (adjusted OR 0.87, 95 per cent c.i. 0.59 to 1.30; P = 0.498). The proportion of surgeons completing the educational modules was an influence: the leak rate decreased from 12.2 per cent (61 of 500) before intervention to 5.1 per cent (24 of 473) after intervention in high-engagement centres (adjusted OR 0.36, 0.20 to 0.64; P < 0.001), but this was not observed in low-engagement hospitals (8.3 per cent (59 of 714) and 13.8 per cent (61 of 443) respectively; adjusted OR 2.09, 1.31 to 3.31). Conclusion Completion of globally available digital training by engaged teams can alter anastomotic leak rates. Registration number: NCT04270721 (http://www.clinicaltrials.gov)
