Revisão sistemática: Eficácia da quimioterapia e associações no tratamento do carcinoma espinocelular em gatos

O carcinoma espinocelular é uma das quatro neoplasias malignas que mais acomete gatos, principalmente os de pele clara e que residem em países tropicais onde a incidência de raios solares é intensa. O tratamento cirúrgico é o mais indicado, mas nem sempre é possível de ser realizado seja pelo estágio avançado do tumor, pela sua localização ou por opção do proprietário que não quer ver seu animal mutilado. O objetivo desta revisão sistemática foi verificar a eficácia da quimioterapia com ou sem associações terapêuticas para o tratamento do carcinoma espinocelular superficial, multicêntrico e de cabeça e pescoço em gatos. Os melhores resultados para o tratamento do carcinoma espinocelular superficial foram observados com a aplicação intralesional do quimioterápico associado à radioterapia ou à eletroterapia, para o tipo multicêntrico faltam trabalhos sobre o assunto e o único encontrado não apresentou resultados satisfatórios. No caso do carcinoma espinocelular de cabeça e pescoço que alberga o pior prognóstico, a terapia multimodal com associação de quimioterapia, radioterapia e excisão cirúrgica demonstrou ser eficiente. Mais estudos sobre o assunto devem ser realizados utilizando um número maior de animais e com um tempo de seguimento mais longo

Perfil de acidentes envolvendo risco biológico em profissionais de saúde de Araçatuba-SP: uma caracterização dos envolvidos

Each year individuals have sought a better quality of life and work, in this case, the science of Bio-insurance needs to keep up with technological advances and the needs of society to minimize or eliminate the risks of accidents. This study evaluated the most common accidents involving health staff from 2007 to 2011 in Araçatuba-SP. 478 accidents were recorded, and 78.7% with percutaneous involvement, 9% with intact skin, 4% with no skin intact, with 7.3 mucous and 1.05% other types of exposures. Most accidents were caused by needles with lumen (68.0%), followed by other agents (14.1%), accidents with blades (8.5%) or needles without lumen (5.5%); 3.7% did not answer and 0.2% were accidents with glasses. When checking the condition in which the accident occurred, 26.0% did not specify, 25.1% occurred in the disposal and / or handling sharp objects, 12.0% at the time of drug administration, 6.9% puncture, 3.7% occurred during recapping the needle. These data show that the most common accidents are those involving needles with lumen and / or sharp objects and due to these factors, the industry of health materials have sought alternatives to minimize such accidents as needles with protective, vacuum collection . Thus, it appears that reporting accidents is important for the development of technical and / or safer materials for patients and health workers.

Análise dos riscos físicos e ergonômicos em roçadora transversal motorizada

According to Statistical Yearbook of Social Security (2011), the number of accidents at work recorded in the agricultural sector is quite high, in the year 2010 there are records of thirty-four thousand nine hundred and ninetysix accidents, and in the year of 2011 there were thirty-one thousand and ninety-six accidents in the industry. Among so many diseases and accidents at work hearing loss is one of them. According to the Pan American Health Organization (2011) the Occupational hearing loss is then jury to the worker's health, often in the workplace. Mechanical vibrations are also present in many human activities exposing employees to an extremely aggressive agent. The combined action of these two factors can cause damage to the health of the worker, in this way, noise and vibration are the two major occupational agents present in the brush cutter operator activity. In the case there is another risk factor, the open work, which exposes the employee to the Sun’s rays and the high temperature indices. Studies have shown that: noise exceeds 115 dB (A) vibration 4.0 m/s2 and thermal stress of 29.9 o C. Ergonomic evaluations also demonstrated that the activity cause injury to workers.

Feasibility of solar heating systems composed of recyclable packaging for low-income rural communities

Solar heaters are an appropriate technology in tropical and sub-tropical climates to heat bath water by solar energy. Low-cost solar heaters meet the demand of low-income rural communities which currently do not have access to this technology. Current research analyzes the economic viability of solar heaters, built with recyclable materials, to reduce electric energy bill. A solar heating system was built consisting of recyclable materials in accordance with the manuals provided by the Secretariat of Environment of the state of Paraná (SEMA). Duration of use of electric showers by families of rural properties was determined to calculate expenses and billing of electricity. Simulation and material costs showed that the system was feasible. Commercial solar heaters could be replaced at a cost of R$ 22.61 per month during 13 months.

Sistema fotovoltaico monocristalino para bombeamento de água

Since ancient times, it has been a huge challenge to all people around the world to manage to get their fresh water, keeping it clean and providing it to every human being, so that it can be used for their daily needs. This is especially true for small properties in the countryside and in isolated areas with low demographic density. Pumping the water in those regions is a solution that rationalizes its use in domestic chores, in animal rearing and in the irrigation systems of cultivated areas. Making feasible local, renewable and non-polluted energetic alternatives is the aim for those areas that are usually far away from the public electric network. Using photovoltaic solar energy is the alternative now proposed. For this objective was built a system with two monocrystalline panels, one pump, two water tanks, two level sensors and a solenoid valve to pump water, using a pump powered an array of monocrystalline solar panels. The main goal was to compare their rate of water flow and their energy consumption. The use of one data acquisition equipment allowed collecting meteorological, electrical and hydraulic values, and also serving for the control and activation of the pumping system. During four months in a row as from April 2009, arrangements with one or two panels were tested. Mathematics correlations and adjustment lines were used to interpret the behavior of obtained dataset. During the analyzed period the system followed the linear equations with great accuracy. The daily average amount of water pumped by the several tested arrays stayed between 1,100 and 2,500 liters, and that is enough to supply a small rural property. The pumping system with two panels effectively showed the major amount of water, but a system with one panel can be an economical solution until 1,500 liters on day. It did not characterize a direct relationship between power or quantity of photovoltaic panels and daily outflow of water pumping.
