Abstract Introduction: The HaDQ is an alternative to conventional hospitalization for clinically stable surgical patients who require complex nursing procedures due to intensity, frequency or characteristics, and control by a surgical specialist at home. Method: Cross-sectional, descriptive and retrospective study of the HADQ activity of our hospital during the first six months of 2020, to analyze the impact of the SARSCov2 pandemic in the unit. Three periods are distinguished: pre-pandemic (Jan-Feb), lockdown (Mar-Apr), post-lockdown (May-Jun). Two groups are differentiated: A (conventional HaD) and B (COVID19 preoperative screening). Various variables were collected: month, type, stay (HaD and hospital), procedures, readmissions, address, type of visits, covid+. A quantitative and qualitative descriptive statistical analysis of the results obtained was carried out. Results: 345 patients were admitted, 225 in group A (phase Pre (34%), Phase C (40%), and phase Post (25%)), and 120 in group B (Phase C (75%), phase Post (25%)). %)). The confinement (phase C) was the most active period of the HADQ, both due to the number of admissions (53%), and the complexity of group A, which required more procedures (71%) and more home visits (52%). There was also an increase in patients from the non-coverage area (42%), which involved medical and nursing visits at the Day Hospital (HD) (21%), and an increase in medical telephone consultations (36%). In the phase Post, the income of group A decreased by 37%. Conclusions: The HaDQ was reorganized due to the pandemic to care for more surgical patients, being an essential care resource, especially during confinement.

Resumen Introducción: La hospitalización a domicilio para pacientes quirúrgicos (HaDQ) es una alternativa a la hospitalización convencional para pacientes quirúrgicos estables clínicamente, que precisen procedimientos de enfermería complejos por intensidad, frecuencia o características, y control por especialista quirúrgico en el domicilio. Método: Estudio transversal, descriptivo y retrospectivo de la actividad de la HADQ de nuestro hospital durante los primeros seis meses del 2020, para analizar la repercusión de la pandemia por SARS-CoV-2 en la unidad. Se distinguen tres periodos: prepandemia (enero-febreo), confinamiento (marzo-abril), posconfinamiento (mayo-junio). Se diferencian dos grupos: A (HaD convencional) y B (despistaje preoperatorio COVID19). Se recogieron diversas variables: mes, tipo, estancia (HaD y hospital), procedimientos, reingresos, domicilio, tipo visitas, COVID+. Se realizó un análisis estadístico descriptivo cuantitativo y cualitativo de los resultados obtenidos Resultados: Ingresaron 345 pacientes, 225 en el grupo A (fase Pre (34%), fase C (40%), y fase Pos (25%)), y 120 en el B (fase C (75%), fase Pos (25%)). El confinamiento (fase C) fue el período más activo de la HADQ, tanto por número de ingresos (53%), como por la complejidad del grupo A que requería más procedimientos (71%) y más visitas domiciliarias (52%). También aumentaron los pacientes de zona de no cobertura (42%), que implicaron visitas médicas y de enfermería en Hospital de Día (HD) (21%), y aumento de consultas telefónicas médicas (36%). En la fase Pos disminuyeron un 37% los ingresos del grupo A. Conclusiones: La HaDQ se reorganizó por la pandemia para atender a más pacientes quirúrgicos, siendo un recurso asistencial esencial, especialmente durante el confinamiento.

ABSTRACT School violence has been a widely studied subject as well as its factors or predictors; In this sense, the objective of this study was to analyze how parenting influences school violence. The study included a systematic review governed by the PRISMA and Cochrane manuals, the explored databases were SCOPUS (346), PROQUEST (97), SCIELO (7) and PUBMED (661), for the search the descriptors and Boolean operators were used. (AND and OR); the preliminary extraction yielded 1111 articles and after applying the selection criteria, 22 were systematized. In this sense, the main results show that parenthood represents a determining factor for the development of adolescent behavior in the face of certain circumstances that arise in the educational context; For this reason, it is considered fundamental that parents assume their roles positively and educate their children with respect and love, avoiding at all times resorting to punishments that affect the physical and emotional state, especially those who are in adolescence due to because they present various psychological changes and have less capacity to regulate their emotions and/or feelings. In conclusion, the absence of positive parenting in the family environment has a negative impact on the behavior of adolescents, which leads to the practice of violent attitudes and psychosocial problems.

RESUMEN La violencia escolar es un tema ampliamente estudiado al igual que sus factores o predictores; en ese sentido, el presente estudio planteó como objetivo analizar cómo la parentalidad influye en la violencia escolar. El estudio comprendió una revisión sistemática regida bajo los manuales PRISMA y Cochrane y las bases de datos exploradas fueron SCOPUS (346), PROQUEST (97), SCIELO (7) y PUBMED (661). Para la búsqueda se utilizó los descriptores y operadores booleanos (AND y OR); la extracción preliminar arrojó 1111 artículos y, luego de aplicar los criterios de selección, se sistematizó 22. En ese sentido, los principales resultados evidencian que la parentalidad representa un factor determinante para el desarrollo del comportamiento de los adolescentes frente a determinadas circunstancias que se presentan en el contexto educativo; por tal motivo, se considera fundamental que los padres asuman sus roles positivamente y eduquen a sus hijos con respeto y amor, evitando en todo momento recurrir a castigos que afecten el estado físico y emocional. De modo especial, se incide en aquellos que están en la etapa de adolescencia, debido a que presentan diversos cambios psicológicos y tienen menor capacidad para regular sus emociones o sentimientos. En conclusión, la ausencia de parentalidad positiva en el entorno familiar repercute negativa mente en la conducta de los adolescentes, lo que conlleva a la práctica de actitudes violentas y problemas psicosociales.

RESUMEN El síndrome de Sjögren (SS) es una enfermedad autoinmune que rara vez afecta al sistema nervioso central. En este informe de caso describimos a un paciente varón, de 68 años, que presentó queratoconjuntivitis seca y xerostomía, y a la evaluación neuropsicológica mostró deterioro cognitivo multidominio en grado de moderado a grave. La resonancia magnética mostró evidencia de paquimeningitis hipertrófica. El estudio del LCR mostró pleocitosis, proteinuria leve y cultivos negativos; el perfil inmunológico positivo anti SS-A, SS-B y la biopsia de la glándula salival compatible con SS. El tratamiento se inició con pulsos de metilprednisolona a una dosis de 1 g/cada 24 h/durante 3 días, control con terapia de mantenimiento, mostrando una respuesta favorable. La meningitis crónica es un desafío para el diagnóstico, entre las causas menos frecuentes está la paquimeningitis hipertrófica en el SS, y con menor frecuencia en los pacientes varones (1/9). Se deben considerar manifestaciones neurológicas inespecíficas, como dolores de cabeza o síntomas neuropsiquiátricos, ya que en algunas ocasiones podemos enfrentarnos a casos raros como el descrito.

ABSTRACT Sjögren syndrome (SS) is an autoimmune disease, rarely affecting the central nervous system. The case is reported on a 68-year-old male patient who presented with keratocon-junctivitis sicca and xerostomia, during neuropsychological evaluation showed moderate to severe multidomain cognitive impairment. The magnetic resonance showed evidence of hypertrophic pachymeningitis. The CSF study showed pleocytosis, mild proteinuria, and negative cultures. The immune positive profile, Anti SS-A, SS-B and salivary gland biopsy was compatible with SS. The treatment was started with methylprednisolone pulses at a dose of 1g every 24 h for three days, and controlled with maintenance therapy, showing a favorable response. Chronic meningitis is a diagnostic challenge; among the less common causes is hypertrophic pachymeningitis in SS, and less frequently in male patients (1/9). Non-specific neurological manifestations should be considered, such as headaches or neuropsychiatric symptoms, as on some occasions rare cases may be encountered, such as the one described.

Resumo O objetivo deste estudo foi avaliar a evolução dos custos para aquisição da cesta básica associados ao poder aquisitivo do salário mínimo, além de mensurar a disponibilidade per capita nos domicílios brasileiros dos alimentos que compõem a cesta básica. Também foram avaliadas a adequação da composição nutricional e a qualidade da dieta baseada no consumo diário de itens da cesta básica. Os resultados obtidos apontam a existência de períodos de elevação de preços para aquisição dos itens da cesta básica, assim como a incapacidade do salário mínimo para o custeio para tais provisões alimentares. Foi verificado que as dietas baseadas no consumo dos itens da cesta básica apresentam quantidade de energia e sódio superiores às recomendações para indivíduos adultos, além de apresentar quantidades insuficientes de cálcio, potássio e vitamina A. A avaliação da qualidade das dietas apontou baixa quantidade de frutas, vegetais, cereais na dieta composta pelos itens das cestas básicas, sendo constatado excesso energético proveniente de gorduras e açúcar de adição. Diante de tais evidências, recomenda-se revisão da composição das cestas básicas para atendimento de requisitos nutricionais básicos em alimentação para população brasileira.

Abstract The scope of this study was to assess the evolution of costs for purchasing the basic food basket associated with the purchasing power of the minimum wage, besides measuring the availability per capita in Brazilian households of the items comprised in the food basket. Additionally, adequacy of the nutritional composition and diet quality based on daily consumption of food basket items was evaluated. The results obtained indicate the existence of periods of price increase for the acquisition of the food basket items, as well as the inability of the minimum wage to meet the cost of such food supplies. It was verified that the diets based on the consumption of food basket items have a higher calorie and sodium content than the recommendations for adults, as well as insufficient amounts of calcium, potassium, and vitamin A. The evaluation of the quality of the diets indicated low amounts of fruit, vegetables, cereals in the diet consisting of the items of the food baskets, with excess calories from fats and added sugar being verified. In view of such evidence, a review of the composition of the food baskets is recommended in order to meet basic nutritional requirements in food for the Brazilian population.

ABSTRACT Background: Disease burden indicators assess the impact of disease on a population. They integrate mortality and disability in a single indicator. This allows setting priorities for health services and focusing resources. Objective: To analyze the burden of neurological diseases in Peru from 1990-2015. Methods: A descriptive study that used the epidemiological data published by the Institute for Health Metrics and Evaluation of Global Burden of Diseases from 1990 to 2015. Disease burden was measured using disability-adjusted life years (DALY) and their corresponding 95% uncertainty intervals (UIs), which results from the addition of the years of life lost (YLL) and years lived with disability (YLD). Results: The burden of neurological diseases in Peru were 9.06 and 10.65%, in 1990 and 2015, respectively. In 2015, the main causes were migraine, cerebrovascular disease (CVD), neonatal encephalopathy (NE), and Alzheimer’s disease and other dementias (ADD). This last group and nervous system cancer (NSC) increased 157 and 183% of DALY compared to 1990, respectively. Young population (25 to 44 years old) and older (>85 years old) were the age groups with the highest DALY. The neurological diseases produced 11.06 and 10.02% of the national YLL (CVD as the leading cause) and YLD (migraine as the main cause), respectively. Conclusion: The burden of disease (BD) increased by 1.6% from 1990 to 2015. The main causes were migraine, CVD, and NE. ADD and NSC doubled the DALY in this period. These diseases represent a significant cause of disability attributable to the increase in the life expectancy of our population among other factors. Priority actions should be taken to prevent and treat these causes.

RESUMEN Introducción: Los indicadores de carga de la enfermedad evalúan el impacto que producen las enfermedades en una población. Integran la mortalidad y discapacidad en un solo indicador. Esto permite fijar prioridades para los servicio de salud y enfocar los recursos. Objetivo: Analizar los datos de carga de enfermedades neurológicas en Perú para el periodo 1990-2015. Métodos: Estudio descriptivo de datos del The Institute for Health Metrics and Evaluation de carga de enfermedad global desde el año 1990 al 2015. La medida de carga de la enfermedad utilizada fue los años de vida ajustados por discapacidad y sus correspondientes intervalos de incertidumbre (95%), que resultan de la suma de los años de vida perdidos debido a muerte prematura y los vividos con discapacidad. Resultados: La carga de enfermedades neurológicas en Perú fue de 9,06 y 10,65% en 1990 y 2015, respectivamente. En 2015, las principales causas fueron: migraña, enfermedad cerebrovascular, encefalopatía neonatal, enfermedad de Alzheimer y otras demencias. Este último grupo y el cáncer del sistema nervioso presentaron un incremento del 157 y 183% de los años de vida ajustados por discapacidad con respecto a 1990, respectivamente. Los adultos jóvenes (25 a 44 años) y adultos mayores (>85 años) fueron los grupos de edad con más años de vida ajustado por discapacidad. Las enfermedades neurológicas produjeron el 11.06 y el 10.02% de los años de vida perdidos debido a muerte prematura (enfermedad cerebrovascular como la causa principal) y años vividos con discapacidad (migraña como la causa principal), respectivamente. Conclusiones: La carga de la enfermedad aumentó un 1,6% entre 1990 y 2015. Las principales causas fueron migraña, la enfermedad cerebrovascular y la encefalopatía neonatal. La enfermedad de Alzheimer y otras demencias y cáncer del sistema nervioso duplicaron los años de vida ajustados por discapacidad en este período. Estas enfermedades representan una causa importante de discapacidad atribuible al aumento de la esperanza de vida de nuestra población, entre otros factores. Se deben tomar medidas prioritarias para prevenir y tratar estas causas.

Abstract The world is undergoing a profound demographic change with a rapid increase in the prevalence of aged individuals. The finitude of life, the burden of senescence and the search for strategies to prolong human life span have troubled humanity since ancient times. However, only in the past few decades we started to understand how organisms age and how life span can be manipulated. Here I give an historical perspective of the aging field and conclude with the notion that aging is controlled by signals from the adipose tissue which are tightly controlled by small non-coding RNAs such as miRNAs.

RESUMO: Descrevem-se os aspectos epidemiológicos e clinico-patológicos de 25 surtos de enfermidade neurológica em bovinos no estado de Santa Catarina causadas por plantas e micotoxinas. Destes, seis corresponderam a intoxicação por Sida carpinifolia, cinco por Solanum fastigiatum, cinco por Phalaris angusta, três por Claviceps paspali, três por Claviceps purpurea e três surtos de etiologia não definida. Os sinais clínicos observados nos bovinos afetados eram de intensidade leve a acentuada e caracterizados por tremores musculares generalizados, incoordenação, hipermetria, aumento da base de sustentação, balanço contínuo de cabeça, olhar atento e movimentos frequentes de orelhas, e em alguns surtos convulsões. Por meio de necropsia foram observadas alterações somente na intoxicação por P. angusta as quais caracterizaram por coloração cinza-esverdeada no tálamo e mesencéfalo. Na histologia, rarefação e/ou desaparecimento de neurônios de Purkinje com substituição por células de Bergmann foram observadas na intoxicação por S. carpinifolia e S. fastigiatum. Na intoxicação por P. angusta foi observado no citoplasma de alguns neurônios do tronco encefálico com pigmentação finamente granular marrom-amarelada. Nos três surtos de enfermidade tremorgênica com etiologia não definida não foram observadas lesões macroscópicas e microscópicas. Experimentos com folhas, flores e sementes de Ipomoea indivisa e Ipomoea triloba e resíduos de milho e soja contaminados com sementes destas duas plantas não produziram alterações clínicas.

ABSTRACT: This study described the epidemiological and clinical-pathological aspects of 25 outbreaks of neurological diseases in cattle caused by plants and mycotoxins in Santa Catarina state. Six of them were due to Sida carpinifolia poisoning, five to Solanum fastigiatum, five to Phalaris angusta, three to Claviceps paspali, three to Claviceps purpurea, and three outbreaks were of unknown etiology. The clinical signs observed in the affected cattle were mild to severe and characterized by generalized muscle tremors, incoordination, hypermetria, wide-based stance, intentional head tremors, dull staring eyes, and frequent ear twitching, with convulsions in some cases. At necropsy, lesions were observed only for P. angusta poisoning, characterized by gray-greenish discoloration in thalamus and midbrain. Microscopically, rarefaction and/or disappearance of Purkinje neurons with substitution by Bergmann cells were observed for S. carpinifolia and S. fastigiatum poisoning. For P. angusta poisoning, thin granular brown-yellowish pigment was observed in the cytoplasm of some neurons. Gross and microscopic findings were not observed in three outbreaks of tremorgenic disease of unknown etiology. Experiments conducted with leaves, flowers and seeds of Ipomoea indivisa and Ipomoea triloba, as well as with maize and soybean residues contaminated with Ipomoea spp. did not reproduced clinical signs.

RESUMO: A transfusão de sangue é um procedimento terapêutico de grande importância para medicina veterinária, apesar disto, na literatura há poucos estudos sobre hemoterapia em caprinos. Este trabalho teve como objetivo avaliar as respostas bioquímicas, hemogasométricas, estresse oxidativo e peroxidação lipídica de caprinos submetidos à transfusão homóloga de sangue total fresco ou armazenado por 15 e 35 dias. Foram utilizados 18 caprinos adultos, machos, submetidos a uma única flebotomia para retirada de 30% do volume sanguíneo e transfundidos com 20mL/kg de sangue total armazenado em bolsas CPDA-1 de acordo com o grupo experimental, sendo: o G0 composto por animais que receberam sangue fresco; G15 e G35 animais que receberam sangue armazenado por 15 e 35 dias, respectivamente. Para a avaliação bioquímica, hemogasométrica, estresse oxidativo e peroxidação lipídica foram coletadas amostras de sangue nos seguintes momentos: antes da indução da anemia (TC0); 6 horas após a flebotomia e antes de transfusão (TC1); 1, 6, 12, 24 e 96 horas após a transfusão (T1, T6, T12, T24 e T96, respectivamente); 8, 16 e 32 dias após a transfusão (T8d, T16d e T32d, respectivamente). Antes da transfusão, amostras de sangue também foram retiradas das bolsas para realização das mesmas análises. As análises estatísticas foram realizadas no programa estatístico GRAPHPAD PRISM 5.0, adotando-se nível de significância de 5%. As bolsas de sangue armazenadas por 15 e 35 dias apresentaram mais alterações bioquímicas, hemogasométricas, estresse oxidativo e peroxidação lipídica do que as bolsas de sangue fresco. Quanto à análise bioquímica, após a transfusão observou-se aumento da proteína total, albumina, glicose e creatina quinase nos 3 grupos; e elevação da bilirrubina total, bilirrubina direta e ureia no G15 e G35. As alterações observadas na análise hemogasométrica não tiveram significado clínico, pois estavam dentro dos valores de referência para a espécie. Os animais que receberam sangue armazenado apresentaram desordem no seu sistema antioxidante demonstrada pela alteração da atividade da SOD. Na análise da peroxidação lipídica não houve diferença entre os grupos para a concentração de malondialdeído. Sendo assim, pode-se concluir que a transfusão de sangue homólogo total fresco ou armazenado em caprinos não comprometeu a gasometria, peroxidação lipídica e funções hepática e renal dos animais transfundidos. Além disso, mostrou-se eficiente em repor entre outros componentes, a proteína total e albumina. Desta forma, a transfusão, conforme realizada neste estudo, mostrou-se segura para ser utilizada na prática clínica desta espécie.

ABSTRACT: Blood transfusion is a therapeutic procedure of great importance for veterinary medicine, in spite of only few studies in the literature on hemotherapy in goats. We aimed to evaluate the biochemical, blood gas, oxidative stress and lipid peroxidation of goats submitted to homologous transfusion of fresh whole blood or stored for 15 and 35 days. Eighteen adult male goats were submitted to a single phlebotomy to remove 30% of the blood volume, and we transfused 20mL/kg of whole blood stored in CPDA-1 bags according to the experimental group, being: G0 composed goats who received fresh blood, G15 and G35 goats that received blood stored for 15 and 35 days, respectively. For the biochemical evaluation, blood gas, oxidative stress and lipid peroxidation, blood samples were collected at the following moments: before the induction of anemia (TC0); 6 hours after phlebotomy and before transfusion (TC1); 1, 6, 12, 24 and 96 hours after transfusion (T1, T6, T12, T24 and T96 respectively); 8, 16 and 32 days after transfusion (T8d, T16d and T32d respectively). Before transfusion, blood samples were also withdrawn from the bags for the same analyzes. Statistical analyzes were performed in the statistical program GRAPHPAD PRISM 5.0, adopting a significance level of 5%. The bags of blood stored for 15 and 35 days showed more biochemical changes, blood gas, oxidative stress and lipid peroxidation than fresh blood bags. As for the biochemical analysis, after the transfusion was observed an increase of the total protein, albumin, glucose and creatine kinase in the 3 groups, and elevation of total bilirubin, direct bilirubin, and urea in G15 and G35. The changes observed in the blood gas analysis had no clinical significance, as they were within the reference values for the species. The goats that received stored blood showed disorder in their antioxidant system through alteration of the SOD activity. In the analysis of lipid peroxidation no difference between the groups for the concentration of malondialdehyde was found. Thus, it can be concluded that transfusion of whole fresh stored blood in goats did not compromise the blood gases, lipid peroxidation and liver and renal functions of the transfused animals. In addition, the method was proved to be efficient to restore, among other components, the total protein and albumin. The transfusion, as performed in this study, proved to be safe for used in the clinical practice of goats.

ABSTRACT Four soybean meal-based diets containing increasing levels of an enzyme complex (E50, E100, E150 and E200 at 50, 100, 150 and 200 g ton-1, respectively) and one soybean meal-based diet without the enzyme complex (E0) were fed in triplicate to M. liza juveniles in a semi-static flow system with 20 fish per tank for 75 days. There were no differences between the treatments for animal performance parameters, but fish fed the enzyme complex treatment exhibited significantly (P<0.05) higher values of calcium bone retention compared with control fish. Although there was no relationship between bacterial counts in different sections of the gastrointestinal tract or enzyme levels, filamentous bacteria were increased in E50 compared with E150. All of the treatments resulted in higher bacterial counts in the stomach than in intestinal segments. Histological screening showed serious to moderate infiltration of inflammatory cells, modification in villus morphology and necrosis in some cases in fish fed the E0 diet. In addition, fish from the E0 treatment exhibited significantly (P<0.05) lower lipid deposition in the peritoneal cavity. Therefore, the use of low levels of exogenous enzyme is recommended in diets for M. liza when soybean meal is used as the main source of protein.

ABSTRACT: The aim of this study was to examine the clinical presentation, biochemical profile and response to treatment among horses with experimentally-induced hypocalcemia. Twelve adult, mixed breed mares were used. A 5% ethylenediaminetetraacetic acid disodium (Na2EDTA) solution was infused into all the mares until the animals presented clinical signs of hypocalcemia, at which point they were divided into a control group (n = 5) and a treatment group (n = 7). The treated group received an infusion of calcium, phosphorus, magnesium and glucose at a dosage of 1 mL/kg/BW during 30 minutes. The control group received 0.9% saline solution at the same dosage. Clinical examination and blood sample collection were performed at the times T0 (baseline- thirty minutes before beginning the Na2EDTA), T1 (at the end of the Na2EDTA infusion), T2 (at the end of the treatment) and T3 (24 hours after the end of the experiment). Serum calcium and magnesium concentrations decreased in response to Na2EDTA administration. The clinical signs of hypocalcemia in the mares included tachycardia, tachypnea, hypophonesis and cecal atony. These signs disappeared over the course of treatment, while total calcium and magnesium increased. Treatment produced recovery from clinical hypocalcemia within 30 minutes and promoted return of the main biochemical parameters to baseline values.

RESUMEN: El objetivo de este estudio fue evaluar la presentación clínica, perfil bioquímico, y la respuesta al tratamiento en los caballos con hipocalcemia inducida experimentalmente. Doce yeguas se distribuyeron en un grupo control (n = 5) y un grupo tratado (n = 7). Ácido etilendiaminotetraacético disódico (Na2EDTA 5%) se infundió a los animales hasta que presentaron signos clínicos de hipocalcemia, momento en el que fueron tratados con una solución comercial con calcio, fósforo, magnesio, y la glucosa en una dosis de 1 mL/ kg / PV de 30 minutos. El grupo control recibió 0,9% solución salina en el mismo volumen. Exámenes físicos y colección de muestras sanguíneas se realizaron en cuatro oportunidades: T0 (basal), T1 (al final de la infusión de Na2EDTA), T2 (al final del tratamiento), y T3 (24 horas después del fin del experimento). Todas las yeguas presentaron una disminución temporal en las concentraciones de calcio total y de magnesio y se observaron signos clínicos de hipocalcemia. En el curso del tratamiento, la taquicardia, taquipnea, hipofonesis, y la atonía del ciego desaparecieron, así como aumentaron las concentraciones de calcio total magnesio. El tratamiento efectuado posibilitó la recuperación de la hipocalcemia clínica dentro de 30 minutos y retorno de las concentraciones de los principales parámetros bioquímicos a los valores basales.

RESUMOO presente trabalho avaliou os efeitos da administração de duas diferentes quantidades de melão sobre variáveis hemogasométricas, bioquímicas e hematológicas de ovinos não adaptados. Foram utilizados 12 ovinos canulados, pesando 25kg de peso vivo, que nunca receberam ração concentrada. Os animais receberam dieta à base de feno (2,3% do peso vivo) e água à vontade. Os ovinos foram distribuídos aleatoriamente em dois grupos e receberam 25% ou 75% da matéria seca (MS) da dieta de melão triturado (G25% e G75%, respectivamente) diretamente no rúmen. Foram realizadas coletas de sangue e determinação do pH ruminal nos seguintes tempos: zero, 3, 6, 12, 18 e 24 horas após oferecimento do melão. Foi realizada análise hemogasométrica, do volume globular, determinação da concentração plasmática de lactato-L, glicose e osmolaridade sérica. No G25%, o pH sanguíneo variou entre 7,40 e 7,31, enquanto o G75% apresentou pH entre 7,38 e 7,26. Maiores concentrações de glicose plasmática foram detectadas no G75% no T3, T6 e T12 (P<0,05). Os ovinos que receberam 25% de melão mantiveram parâmetros sanguíneos dentro da normalidade, ao passo que, no G75%, os ovinos apresentaram discreta acidose metabólica sistêmica e hiperglicemia. A suplementação com 25% de melão pode ser uma alternativa segura na alimentação de ovinos.

ABSTRACTThis study evaluated the effects of two different amounts of melon on blood gas, biochemical and hematological variables of sheep not adapted. We used 12 cannulated sheep weighing 25 kg which never received concentrate. The animals received hay-based diet (2.3% of body weight) and water ad libitum. The sheep were randomly divided into two groups and received 25% or 75% of the dry matter (DM) of the diet of crushed melon (G25% and G75%, respectively) directly into the rumen. Blood collection and determination of ruminal pH were made at the following times: zero, three, six, 12, 18 and 24 hours after administration of the fruit. In whole blood was performed blood gas analysis and packed cell volume; in the plasma it was determined the concentrations of L-Lactate and glucose and in the serum the osmolarity. At G25% the blood pH ranged between 7.40 and 7.31, while G75% showed pH between 7.38 and 7.26. Higher concentrations of plasma glucose were detected in G75% after 3, 6 and 12 hours (P <0.05). Sheep receiving 25% of melon showed blood parameters within the normal range, while in the G75%, sheep had a mild systemic metabolic acidosis and hyperglycemia.
