#1 - Randomized controlled clinical trial of ketoanalogues supplementation in dogs with chronic kidney disease
Abstract in English:
The objective was to verify the effectiveness of ketoanalogues in dogs with Chronic Kidney Disease (CKD) stage 3. Controlled randomized clinical trial was performed with twenty dogs with CKD stage 3. Animals were subjected to: Group 1 (control): conventional therapy (CT) for CKD; Group 2: CT and 60mg/kg, OA, q48h of keto-supplementa; Group 3, CT and 60mg/kg, OA, q24h of keto-supplementa; and Group 4, CT and 120mg/kg, OA, q12h of keto-supplementa. All dogs received canine renal diet. Animals were evaluated at the beginning of therapy and after 15 and 30 days. Complete blood count (CBC), serum urea, creatinine, phosphorus, calcium, potassium and sodium and urine protein/creatinine (UPC) ratio were analyzed. The use of ketoanalogues in dogs with CKD stage 3 during the period of 30 days showed no efficacy, in any of the studies dosages, to improve signs and symptoms of the disease, improve the values of CBC, reduce serum urea and creatinine, normalize electrolytes or reduce UPC. It is concluded that the use of ketoanalogues does not impact the clinical outcomes in dogs with CKD stage 3.
Abstract in Portuguese:
O objetivo foi de verificar a eficácia da suplementação com cetoanálogos em cães com Doença Renal Crônica (DRC) grau 3. Um ensaio clínico controlado e randomizado foi realizado com 20 cães com DRC grau 3. Os animais foram divididos em 4 grupos: grupo 1 (controle): terapia convencional (TC) para DRC; grupo 2: TC e 60mg/kg, VO, q48h de cetoanálogoa; grupo 3: TC e 60mg/kg, VO, q24h de cetoanálogoa; e grupo 4, TC e 120mg/kg, VO, q12h de cetoanálogoa. Todos os cães receberam ração renal para cães. Os animais foram avaliados no início da terapia e após 15 e 30 dias. Hemograma completo, ureia, creatinina, fósforo, cálcio, potássio e sódio séricos e a razão proteína creatinina (RPC) urinária foram analisados. Foi verificado que o uso dos cetoanálogos em cães com DRC grau 3 durante 30 dias não mostrou eficácia, em nenhuma das dosagens utilizadas, em melhorar os sinais clínicos e sintomatologia da doença, os valores do hemograma e ureia e creatinina séricos, normalizar eletrólitos e reduzir RPC. Concluiu-se que o uso de cetoanálogos não impacta na melhora de sintomatologia clínica em cães com CKD grau 3. Como esse parece ser o primeiro ensaio clínico sobre cetoanálogos em cães com CKD, mais estudos podem ser necessários com maior acompanhamento e maiores grupos.

Clinical evaluations of newborns, as well as defining the therapeutic decision, represent significant challenges to the veterinarian. This study aimed to evaluate neonatal vitality using the modified Apgar score and blood glucose, lactate, and cortisol concentrations in newborn equines. Twenty foals of the Paint Horse breed born by normal delivery were evaluated during the first 48 hours of life. The modified Apgar score was determined at birth and 10 minutes later, with values ranging from 0 to 10. Blood samples for the laboratory tests were collected at birth and at 4, 8, 12, 16, 20, 24, 36, and 48 hours. The mean Apgar score was significantly lower at birth than at 10 minutes (p < 0.001). Blood glucose concentrations increased significantly between birth (98.90 ± 35.97 mg/dL) and 8 hours (127.90 ± 27.15 mg/dL), stabilizing after the first 12 hours (148.95 ± 29.59 mg/dL). Serum lactate concentrations showed a significant decrease across the time points tested, with the highest value occurring at birth (5.48 ± 2.17 mmol/L) and stabilizing after 24 hours (2.76 ± 1.31 mmol/L). Cortisol concentrations significantly decreased (p < 0.01) between 4 (10.46 ± 7.46 µg/dL) and 48 hours (5.21 ± 3.35 µg/dL), with the highest value occurring 4 hours after birth. The common occurrence of laboratory abnormalities in healthy newborn foals reinforces the need to conduct regular clinical examinations and to develop laboratory reference values ​​for different breeds and ages.

A avaliação clínica dos recém-nascidos, bem como a definição da conduta terapêutica adotada representam expressivos desafios ao Médico Veterinário. O objetivo deste estudo foi avaliar a vitalidade neonatal pelo escore de Apgar modificado, glicemia, lactatemia e cortisol em neonatos equinos. Para tal, foram utilizados 20 potros da raça Paint Horse, nascidos em eutocia, durante as primeiras 48 horas de vida. O escore de Apgar modificado foi realizado ao nascimento e 10 minutos após, atribuindo-se notas de 0 a 10. As colheitas das amostras de sangue, para a realização das análises laboratoriais, ocorreram nos momentos ao nascimento, 4, 8, 12, 20 16, 20, 24, 36 e 48 horas de vida. A média do escore de Apgar ao nascimento foi significativamente menor que aos 10 minutos (p<0,001). A glicemia aumentou significativamente entre o nascimento (98,90 ± 35,97 mg/dL) e às 8 horas (127,90 ± 23 27,15 mg/dL), com estabilização após as primeiras 12 horas (148,95 ± 29,59 mg/dL). A concentração sérica de lactato apresentou decréscimo significativo entre os momentos estudados, sendo o maior valor encontrado ao nascimento (5,48 ± 2,17 mmol/L), com estabilização a partir das 24 horas (2,76 ± 1.31 mmol/L). As concentrações de cortisol, reduziram significativamente (p<0,01), entre as 4 (10,46 ± 7,46 µg/dL) e as 48 horas (5,21 ± 3,35 µg/dL), sendo o maior valor encontrado as 4 horas após o nascimento. A ocorrência comum de anormalidades laboratoriais em potros recém-nascidos, aparentemente saudáveis, reforça a necessidade da realização de exames clínicos regulares e o desenvolvimento de valores laboratoriais de referência, em diferentes raças e idades.

The poisonous snakes of the genera Crotalus and Bothrops have been kept in captivity with the purpose of extracting poison for the production of immunobiological. Knowledge of the physiology of these animals and serum proteins concentration changes are important for early identification of major diseases which lead to states of hypoproteinemia and hyperproteinemia. The objective was to determine the concentration of total protein and serum protein electrophoresis profile of Crotalus durissus terrificus (rattlesnake) in captivity. Blood samples were taken from the ventral coccygeal vein of 21 adult and healthy snakes divided into groups: Group 1 with 12 males, weighing in average 588.89±193.55g, and Group 2 with nine females, weighing in average 708.33±194.04g. The total serum concentration of protein was determined by the method of refractometry and agarose gel electrophoresis. The total protein values in the serum for females was 4.82±0.72, for males 4.51±0.50 and males and females 4.64±0.61, identified by four fractions (g/dL): albumin, a, b and g-globulin. Additionally the albumin/globulin ratio was calculated. The female snakes showed higher values for the variables, albumin and the albumin/globulin (AG) differed significantly (P<0.05) from the group of male snakes, but there was no clinical significance.
