Abstract: Objetivou-se avaliar os efeitos da aduba o química e organica sobre a composi o químico-bromatológica do capim elefante, além de estimar a energia líquida do volumoso e os nutrientes digestíveis totais desta forrageira. Foram formadas duas áreas de capineiras e utilizados dois sistemas de aduba o. Utilizou-se delineamento em blocos (seis períodos), casualizados completos e três repeti es por volumoso (aduba o química e aduba o organica) por bloco. Os dados de proteína bruta, fibra em detergente neutro, cinzas, cálcio, magnésio, potássio e fósforo foram avaliados pelo teste F, a 5% de probabilidade. Com base na fibra em detergente neutro, estimou-se a energia líquida do volumoso e os nutrientes digestíveis totais do capim-elefante nos dois sistemas de aduba o. Com base nos resultados, observa-se que o capim-elefante submetido à aduba o organica apresenta maiores valores em sua composi o químico-bromatológica. Foram observados nesta forragem submetida à aduba o organica, maiores teores de proteína bruta (17,26%), cinzas (26%) e fósforo (36,88%) e menores teores de fibra em detergente neutro (3,96%) em rela o ao capim-elefante submetido à aduba o química. A aplica o de esterco de curral na capineira de capim-elefante melhorou o teor de matéria organica no solo, o que propiciou melhoria na composi o químico-bromatológica, além de proporcionar maior flexibiliza o na frequência de utiliza o da capineira em rela o à adubada químicamente. The objectives of this work were to study the effect of chemical and organic fertilization on the forage dry matter chemical composition characteristics of elephant grass and to estimate the total net energy of forage and the total digestible nutrients. Two elephant grass stocking piles were formed and two fertilization systems were used. Soil and plant evaluations (chemical and physical analysis) were performed at field. Was carried out in a completely block (six periods) randomized design and three replicates per forage (chemical and organic fertilization) per block. Data of crude protein, neutral detergent fiber, and ashes, calcium, phosphorus, magnesium and potassium were evaluated by F test, at 5% of probability. Based on the total digestible nutrients contents, the total net energy and total digestible nutrients of the elephant grass from the two fertilization systems were estimated. The elephant grass submitted to fertilization organic showed higher chemical composition values. In this forage, higher contents of crude protein (17.26%), ashes (26%) and phosphorus (36.88%) and smaller of neutral detergent

Abstract: Este trabalho investigou a influência da percep o de saúde organizacional sobre o stress no trabalho dos funcionários de restaurantes da cidade de Santa Maria – RS. Para tanto, utilizou-se uma survey com os funcionários de sete restaurantes, três públicos e quatro privados. Realizou-se uma análise fatorial que apresentou cinco fatores para stress no trabalho e quatro fatores de saúde organizacional. Através de uma análise de correla o, confirmou-se a multidimensionalidade desses construtos. Dados esses resultados, para verificar a influência da percep o de saúde organizacional sobre o stress ocupacional, realizou-se uma análise de regress o e foram encontrados cinco modelos válidos que atendem aos pressupostos necessários. Entretanto, esses modelos tiveram baixo poder de explica o, indicando que os fatores de stress ocupacional n o s o suficientes para explicar a saúde organizacional, devendo ser investigados outros aspectos relativos ao ambiente laboral que interferem na percep o de stress no trabalho.

Abstract: The paper describes three cases of pertrochanteric fractures that were treated with PFN with two interlocking screws that evolved to either Z-effect or reverse Z-effect. Literature-based explanations for this phenomenon are provided together with recommendations of how to avoid such complications.Although intramedullary fixation is an established method of treatment of femoral intertrochanteric and subtrochanteric fractures, the evolution of the procedure may include complications associated with the migration of the interlocking head screws. The occurrence of Z-effect and reverse Z-effect has not been completely elucidated, but the main causes of such complications are probably fracture fixation in varus position, severe medial comminution, inappropriate entry point of the nail and poor bone quality.The incidence of fractures of the proximal femur has increased considerably over the last few decades as a consequence of the greater longevity of the population [1]. Femoral pertrochanteric fractures (FPF) typically occur in patients presenting diverse types of comorbidities and are associated with a high rate of mortality in the first year after the event [2].In the present paper, we describe the complications observed in three patients arising from surgical treatment of FPF with proximal femoral nails (PFN) comprising two interlocking head screws that migrated in opposite directions (Z-effect and reverse Z-effect). The possible causes of these complications and relevant preventive methods are discussed.A 44-year old male doctor (with no comorbidities), who had been injured in a car accident, presented subtrochanteric fracture (AO/OTA 32-B1) of the right femur and was submitted to osteosynthesis with PFN (Hexagon?, Campinas, SP, Brazil) one day after the trauma. The femur fracture was classified as level 3 on the abbreviated injury scale (AIS), whereas the injury severity score (ISS) was level 9 without any associated injuries. After 10 months, the patient evolved wit

Abstract: O estudo objetivou analisar a percep o dos enfermeiros sobre o uso do Sistema de Informa o da Aten o Básica (SIAB), na Estratégia Saúde da Família (ESF), em cinco municípios do sul do país. Foram entrevistados cinco enfermeiros, e os dados foram analisados seguindo os passos da análise temática, fazendo emergir duas categorias: possibilidades de uso do SIAB e desafios enfrentados no cotidiano dos enfermeiros com o uso do SIAB. Salienta-se a importancia das Coordenadorias Regionais de Saúde na organiza o de capacita es e discuss es sobre o SIAB, além de assessorar os municípios na implanta o efetiva desse sistema na aten o básica, envolvendo gestores, trabalhadores e comunidade. Um maior envolvimento desses atores na consolida o do SIAB facilitaria e qualificaria as a es de planejamento em saúde da popula o. El objetivo del estudio fue analizar la percepción de las enfermeras sobre el uso del Sistema de Información de Atención Primaria (ISPC) en la Estrategia de Salud de la Familia (ESF) en cinco ciudades en el Sur. Cinco enfermeras fueron entrevistados y los datos fueron analizados siguiendo los pasos de análisis temático, surgen dos categorías: las posibilidades de utilizar el SIAB y desafíos que enfrenta en el diario de los enfermeros con el SIAB. Destaca la importancia de la Coordinación Regional de Salud en la formación de la organización y los debates sobre el SIAB, y ayudar a los municipios en la aplicación efectiva de este sistema en la atención primaria, la participación de gerentes, empleados y la comunidad. Una mayor participación de estos actores en la consolidación de facilitar la SIAB y calificar las acciones de la planificación de la salud de la población. The study aimed to analyze the nurses' perception about the use of the Information System of Primary Care (ISPC) in the Family Health Strategy (FHS) in five cities in the South. Five nurses were interviewed and data were analyzed following the steps of thematic analysis, two categories emerge: possibilities of using the ISPC and challenges faced in everyday nurse using the ISPC. Stresses the importance of the Regional Health Coordination in organizing training and discussions on the ISPC, and assist municipalities in the effective implementation of this system in primary care, involving managers, employees and community. Greater involvement of these actors in the consolidation of ISPC facilitate and qualify the actions of the population health planning.

Abstract: the present research aimed to describe possible histopathological alterations in the reproductive system (testicles and epididymis) of male dogs experimentally infected with toxoplasma gondii. canines (n=10) serologically negative for t. gondii were selected and distributed into three experimental groups: gi, 3 inoculated with 2.0 x 105p strain oocysts; gii, 3 infected with 1.0 x 106rh strain tachyzoites; and giii, 4 control dogs. antibody research (ifat) against t. gondii was realized. toxoplasma gondii infection was confirmed by seroconversion of the 6 males infected with tachyzoites and oocysts from postinoculation day (pid) 7 and 14, respectively. at pid 70, all dogs were submitted to orchiectomy and testicle and epididymis samples were collected and histologically processed for examination under optical microscope. the following alterations were diagnosed: mild and moderate mononuclear inflammatory infiltrate in the epididymis, moderate cellular edema, hydropic degeneration and moderate interstitial fibrosis in seminiferous tubules. the histopathological results in the present research, isolation of t. gondii in testicle and epididymis fragments by immunohistochemistry and results from the literature by other authors in different tissues, all infer that the alterations observed in dogs infected with t. gondii are suggestive of toxoplasmic infection.
