RESUMO
Healthcare-associated infections (HAI) are illnesses acquired during healthcare and are often the most important adverse event during healthcare. With the aim of increasing the effectiveness of disinfection/decontamination processes in the health service with safe and not promote microbial resistance, we propose the development of portable equipment associated with type C ultraviolet light (UVC). The efficiency of the irradiance emitted by the equipment (at dosages 3.5, 5.0, and 60 mJ/cm2) was determined by the action exerted after exposure against four different bacterial (Acinetobacter baumannii, Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus) and three different fungi (Candida albicans, C. parapsilosis, and Aspergillus section Fumigati). It was possible to observe that all treatments were capable of inactivating the bacterial species evaluated (p < 0.05), causing the irreversible death of these microorganisms. The most effective elimination of fungal agents was at a dose of 60 mJ/cm2 of UVC radiation, with a decrease in the fungal inoculum varying between 94% and 100% in relation to the control without exposure. Thus, our study showed that the application of the portable prototype with UVC light (254 nm) at a distance of 48 mm, allowed an average irradiance of 3.5 mW/cm2, with doses of 3.5 ≈ 60 mJ/cm2 (from 1 to 60 s of exposure), which can promote the total reduction of the bacteria evaluated and significantly reduce fungal growth. Therefore, this prototype could be used safely and effectively in the hospital environment, considerably reducing contamination and contributing to the reduction of healthcare-associated infection risk.
RESUMO
Objetivo: analisar um programa piloto de promoção de saúde com trabalhadoresmarítimos de rebocadores baseado no estímulo à prática de atividade físicaregular e no acompanhamento nutricional. Metodologia: fizeram parte do estudo10 trabalhadores do porto do Rio Grande, sul do Brasil, que foram submetidosa um programa de 22 semanas, composto de atividade física e acompanhamentonutricional regular. Antes e após a intervenção foram realizadasas seguintes avaliações: física, bioquímica sanguínea, VO2 máximo e qualidadede vida (WHOQOL Bref). Na análise foram utilizados os testes t de Studentpareado, o de Wilcoxon e o de Correlação de Pearson. Resultados: foi verificado diminuição na média de peso (84,3 vs. 82,1 kg; p = 0,03), da circunferênciaabdominal (97,1 vs. 91,7 cm; p = 0,005) e do quadril (103,5 vs. 100,7 cm;p = 0,005). O tempo de atividade física se correlacionou com a redução da circunferência abdominal (r = 0,636; p = 0,048) e com o índice cintura-quadril(r = 0,683; p=0,03). Houve redução no número de trabalhadores com triglicerídeos alterados (7 vs. 3; p = 0,04). A análise da qualidade de vida não apresentou alteração. Conclusão: o modelo de intervenção de promoção de saúdeproposto mostrou, para os trabalhadores participantes, resultados positivos em parâmetros importantes para o risco cardiovascular.
Objective: To analyze a pilot study on health promotion for maritime tugbo at workers. Methodology: Ten tugboat workers from Rio Grande harbor locatedin Southern Brazil participated in a 22 week program, consisting of physical activity and regular nutritional counseling. Physical tests, blood biochemistry,VO2 max, and test on quality of life (WHOQOL Bref) were applied before and after the intervention. Paired Student t test, Wilcoxon test, and Pearson correlation were used. Results: Decrease on weight (84.3 x 82.1 kg;p = 0.03), waist circumference (97.1 x 91.7 cm; p = 0.005) and hipcircumference (103.5 x 100.7 cm; p = 0.005) was observed. Physical activity duration showed correlation with reduction of waist circumference (r = 0.636; p = 0.048) and waist-hip ratio (r = 0.683; p = 0.03). The number of workers with elevated triglycerides was reduced (7 vs. 3; p = 0.04). Lifequality results did not alter. Conclusion: The health promotion intervention model showed positive results in important parameters for cardiovascular risk among tugboat workers under study.
