Hantavirus and criminality: disease and family

Background and objectives: Hantavirus is a pathogen that causes a viral disease with an acute and severe presentation, and a high mortality rate. In face of a sudden loss, some families may not conceive the complete absence of the deceased relative. Thus, we sought to understand the changes that took place in a family after the death of the provider by Hantavirus Pulmonary Syndrome (HPS). Methods: A descriptive exploratory study with a qualitative approach of the type case report. Data collection took place between October and December 2016 through recorded individual interviews and using questions about family dynamics after family provider’s death of HPS, which were assessed by content analysis in the light of Roy's theory. Results: It was observed that the illness and death of the family patriarch weakened the family's strengths and resources, leading to a period of mourning and despair. In addition, unemployment among other family members worsened socioeconomic conditions, seeing drugs as an alternative for support as it became a commercial activity, and the rise of a command in the region that culminated in the arrest of the wife, two daughters and a son of the deceased. Conclusions: In this case, it was evidenced that the family was weakened due to the illness and death of their loved one by HPS, and because of the lack of support and welcome from the reference social services, they chose to act in criminality and it ended up with the arrest of four members

Avaliação da qualidade higiênico-sanitária da água de poços rasos localizados em uma área urbana: utilização de colifagos em comparação com indicadores bacterianos de poluição fecal

Foram submetidas às contagens de colifagos, coliformes totais, coliformes fecais e de estreptococos fecais, 104 amostras de água colhidas de 8 poços rasos localizados na área urbana do Município de Jaboticabal, SP, Brasil, com a finalidade de avaliar as condições higiênico-sanitárias e de verificar as correlações existentes entre o número de colifagos e o de bactérias indicadoras de poluição fecal. Os resultados obtidos evidenciaram a ocorrência de 96 (92,3%) amostras fora dos padrões bacteriológicos de potabilidade estabelecidos pelo Ministério da Saúde, monstrando ser precárias as condições higiênico-sanitárias das águas analisadas. Os achados evidenciaram a inexistência de correlação entre o número de colifagos e os números de bactérias indicadoras de poluição fecal

Sensitivity To Beta-adrenoceptor Agonists Of Adipocytes From Rats Treated With An Aqueous Extract Of Croton Cajucara Benth.

Aqueous extracts of Croton cajucara bark are used in folk medicine to treat hepatic and gastrointestinal disorders and as a coadjuvant in weight-loss programs. We examined the effect of treating rats for 15 days with a 5% aqueous extract of C. cajucara on body weight and food intake. The epididymal adipose pads were removed and the lipolytic responses of isolated adipocytes to isoprenaline, noradrenaline (norepinephrine), BRL37344 and adrenaline (epinephrine) were analysed in the absence or presence of metoprolol or ICI118,551. Treated rats had a significantly lower weight gain than control rats, with no difference in food and liquid intake, epididymal fat-pad weight or basal glycerol release. The sensitivity of the lipolytic response to isoprenaline and adrenaline was significantly higher in adipocytes from treated rats. The sensitivity to noradrenaline or BRL37344 was unaltered. Metoprolol shifted the dose-response curves to noradrenaline to the right in adipocytes from control and treated rats; the dose-response curve to isoprenaline in adipocytes from control rats was also shifted to the right. In adipocytes from treated rats, the dose-response curve to isoprenaline was unaltered by metoprolol but was shifted to the right by ICI118,551, a beta(2)-adrenoceptor antagonist. We conclude that in adipocytes from treated rats there is an increase in the lipolytic response to non-selective agonists (isoprenaline and adrenaline) mediated by beta(2)-adrenoceptors, with no alteration in the responses mediated by beta(1)-adrenoceptors (noradrenaline) or beta(3)-adrenoceptors (BRL37344). This effect could increase the role of adrenaline as an endogenous stimulator of lipolysis.55253-

Limites da estabilidade lateral de tratores agrícolas para plantações forestais em áreas inclinadas

Neste estudo, avaliou-se a estabilidade lateral de tratores no preparo do solo para plantações forestais e determinou-se o ângulo máximo de segurança para a circulação de tratores agrícolas em áreas declivo-sas. A determinação desse ângulo máximo de inclinação foi atingida de acordo com a posição do centro de gravidade do trator e confrmada por testes de campo. Para o equilíbrio estático, com o trator parado, o limite de inclinação máxima foi calculada em 25,10°, acima desse valor o trator tomba de lado. Com a máquina em movimento, as irregularidades da superfície do terreno podem mudar o ângulo do plano de apoio, e, assim, obteve-se o limite de inclinação operacional de 23,70°. No plantio mecanizado, o conjunto trator-subsolador atingiu 87,89% da área estimada pela inclinação máxima de 23,70°, considerando um coefciente de segurança de 50%. Concluiu-se que a rugosidade da superfície e inclinação do terreno foram limitantes para o desempenho das máquinas no preparo do solo para as culturas forestais e a sub-solagem resultou em praticamente 88% da área defnida pelo limite de inclinação de 23,70°. _______________________________________________________________________________ ABSTRACTThe lateral stability of tractors to prepare land for forest plantations and maximum angles of security for the movement of farm tractors in steep areas were evaluated. The determination of these maximum inclination angles was achieved according to the position of center of gravity of the tractor and confrmed by feld tests. For static equilibrium, with the tractor stopped, the limit of maximum slope was 25.10°. With the machine in motion, due to surface irregularities of the terrain and the angle of the support plan, the operational limit for the slope was 23.70°. The tractor-subsoiler reached 87.89% of the area estimated for the maximum inclination of 23.70° in mechanical tillage, with a safety factor of 50%. The slope and surface roughness of the terrain limited the performance of moving machinery for soil preparation for forestry, and the subsoiling resulted in 88% of the area defned by the slope limit of 23.70°
