Abstract: despite the frequent use of dry and fibrous roughage for feeding cows in many regions, especially during the dry season, impaction of the abomasum has been poorly reported in brazil, probably because the condition is misdiagnosed by practitioners. the present paper aimed to accomplish a retrospective study on primary abomasal impaction in 14 cattle from pernambuco state, northeastern brazil. eight moderate cases, without severe abdominal distention and with no rumen compaction, were treated conservatively, and four severe cases, with severe abdominal distention and rumen compaction, were treated surgically. one bull was slaughtered and one cow died without treatment. the greater number of abomasal impaction cases was in holstein cows with six cases (42.9%), followed by crossbred cattle with five cases (35.8%), and the breeds brown-swiss, nelore and marchigiana, each with one case (21.3%). the food composition was characterized by low quality fibers and varied greatly among cases. most frequent clinical signs were apathy, dehydration, hypomotility and ruminal bloat, intestinal hypomotility and scanty or absent feces with mucus. the hematological findings revealed leukocytosis with neutrophilia and hyperfibrinogenemia in most cases. ruminal fluid analysis showed compromised flora and fauna dynamics and increased chlorine ion concentration. clinical (4/8) and chirurgical (2/4) recovery rate achieved 50%. the clinical and chirurgical methods remain as viable options for the treatment of light and severe impaction, but the prognosis is always reserved especially when associated to late pregnancy.

Abstract: the continuous genetic selection for high milk production in association with greater digestive capacity and corporal depth increases the susceptibility for abomasopathies including abomasal displacement. the present work aimed to accomplish a retrospective study on abomasal displacement in 36 cattle attended at bovine clinic, garanhuns campus, federal rural university of pernambuco, through january 2000 to february 2009. twenty seven cases of right abomasal displacement, six cases of left abomasal displacement and three of abomasal volvulus were diagnosed. eleven moderate cases, without severe abdominal distention, appetite for roughage and metallic sound (“ping”) reaching at the most the 8th intercostal space were treated conservatively, and 20 severe cases with moderate to severe abdominal distention associated to systemic disturbances were treated surgically. two cows were euthanized due to diffuse peritonitis or severe alterations in the abomasal serosa totalizing 18 animals submitted to the surgical treatment. two animals were slaughtered and three cows arrived prostrated and died without receiving any treatment. risk factor analysis identified rainy season as statistically significant. the greater number of abomasal displacement was in crossbred cows with 24 cases (66.6%), followed by holstein and gir cattle with 11 (30.5%) and one (2.9%) cases, respectively. food composition varied greatly and characterized by excess of carbohydrates and in most cases low quality fibers. most frequent clinical signs were apathy, dehydration, light to severe ruminal bloat with reduced or absent motility, splashing sound during right flank ballottement, ping and a distended viscera-like structure in the side of the displacement; liquid, blackish and fetid feces. hematology reveals leukocytosis with neutrophilia and hyperfibrinogenemia in most cases. ruminal fluid analysis showed compromised flora and fauna dynamics and increased chloride ion concentration in 93.9% of the cases

Abstract: due to the fact that bioethics is an area of knowledge which encompasses several disciplines, and due to its rapid development in a short time, academic challenges have been produced. the teaching of bioethics has become a new experience which has no definite didactic model. it is clear that traditional teaching, which is based on a disciplinary concept, has not been efficient to allow a complete understanding of bioethics. bioethics deals with knowledge in the cross-roads of several disciplines, suggesting a transdisciplinary concept for its teaching. bioethics philosophical foundation, as those developed in european countries, strengthens its transdisciplinary dimension and recognizes anthropology (cultural and philosophical), as the theoretical support for its teaching. thus, considering that brazilian and european cultural and moral values are relatively similar, the european concept of bioethics seems to be more adequate to support the teaching of bioethics in brazil.

Abstract: outbreaks of a disease of the nervous system are reported in cattle in three farms in the agreste region of the state of pernambuco. morbidity, mortality and fatality rates varied from 3 to 25%, 0 to 20% and 0 to 60%, respectively. a weed found in large amounts in the pastures was identified as solanum paniculatum. clinical signs were characterized by transitory, periodic attacks with loss of balance, incoordinated gait, neck and head extension, hypermetria, intention tremors, nystagmus, and falls. the attacks were induced when the animals were disturbed or by the application of the head raising test. two cows showed permanent signs including ataxia, abnormal posture, staggering gait with limbs in abduction, intention tremors, hypermetria, and progressive weight loss. histological lesions in one cow were fine vacuolation of the cerebellar purkinje neurons with marginalization of the nucleus. loss of purkinje neurons with proliferation of bergmann astrocytes and wallerian degeneration with axonal spheroids in the granular layer and cerebellar white matter were also observed. neuronal vacuolation and axonal spheroids were observed in the gracillis nucleus. in one cow that stayed for approximately 10 months in an area free of s. paniculatum with permanent signs, there was a severe depletion of purkinje neurons in the cerebellum. the granular and molecular layers were reduced and depleted of cells. considering that the toxic compound of s. paniculatum is unknown, and that the plant is largely used as a medical plant, it is necessary to take into account the risk of human poisoning.

Abstract: Objective: Cardiovascular diseases are the most common causes of morbidity and the leading cause of mortality in the world scenario, accounting for about 20% of all deaths in individuals over 30 years. It has attributed this to the increase in the company’s exposure to risk factors. It identifies cardiovascular risk factors in the nursing team and compares the cardiovascular risk by Framingham score among professionals of middle and upper working in a referral hospital in cardiology. Method: Cross-sectional quantitative study was conducted in 2014, in a reference hospital in cardiology located in Recife/Pernambuco, Brazil. Data of cardiologic risk factors were collected from 82 nursing team members, comprised of technical, auxiliary nurses, and nurses between 30 and 74 years of age. The cardiovascular risk level was evaluated by the Framingham Score. Data were organized and analyzed by means of the SPSS, with descriptive statistics and Student-t test for the continuous variables. Results: Family history, stress and sedentary life style were the prevalent risk factors in more than half of the professionals. Only 5.23% of the technical and auxiliary nurses had a high risk score for cardiovascular event. Conclusion: The data indicates a low cardiovascular risk for these professionals and the presence of risk factors that can be modified. Health surveillance of these professionals is necessary in order to avoid a change to a risk of greater vulnerability.

Abstract: Este trabalho teve por objetivo determinar as exigências líquidas de zinco (Zn), cobre (Cu) e ferro (Fe) de cordeiros Santa Inês em pastejo na regi o semiárida. Os animais com peso vivo entre 20 e 30 kg apresentaram conteúdo corporal no peso de corpo vazio (PCV) para esses minerais de 60,26 a 76,37 mg kg-1, 10,78 a 16,72 mg kg-1 e 133,44 a 126,98 mg kg-1, respectivamente. Observou-se que com o aumento do PCV, as concentra es de Cu e Zn também aumentavam, enquanto a de Fe diminuía. As exigências líquidas para cordeiros em regime de pastejo variaram de 1,69 a 7,86 mg dia-1 para Cu e 7,20 a 27,4 mg dia-1 para Zn. Os resultados obtidos no presente trabalho, para exigências desses minerais, foram maiores do que as exigências dietéticas recomendadas pelo do NRC (1985), que s o de 7 a 11 mg, com máximo de 25 mg e de 20 a 30 mg, com máximo de 750 mg kg-1 de alimento, para Cu e Zn, respectivamente. As exigências líquidas de Fe variaram de 8,46 a 26,66 mg dia-1, e portanto, menores do que as recomendadas pelo NRC (1985) para este mineral que s o de 30 a 50 mg kg-1 de alimento. This work had as an aim determine the net requirements of Zinc (Zn), Copper (Cu) and Iron (Fe) of Santa Inês lambs raised grazing in the semi-arid area. Animals with body weight between 20 e 30 kg showed corporea contents in empty body weight (EBW) in these minerals from 60.26 to 76.37 mg kg-1, 10.78 to 16.72 mg kg-1 and from 133.44 to126.98 mg kg-1, respectively. It was observed that increasing the PCV increased Cu and Zn concentration but decreased the Fe concentratiêson. The net requirements for lambs under pasture varied from 1.69 to 7.86 mg day-1 for Cu and from 7.20 to 27.4 mg day-1 for Zn. The results obtained in the present experiment suggest that the dietary requirements in Cu and Zn are higher than those recommended by NRC (1985), between 7 and 11 mg, with a maximum value of 25 mg for Cu and between 20 and 30 mg, with a maximum of 750 mg kg-1 of food for Zn, respectively. The net requirements for Fe varied from 8.46 to26.66 mg day-1 and were lower than that recommended by NRC (1985) for this mineral, from 30 to 50 mg kg-1 of diet.
