Tratamento de esgoto de uma unidade de ensino superior por meio de um sistema de zona de raízes

O uso de plantas no tratamento de águas residuais é uma alternativa eficiente, sustentável e de baixo custo em comparação ao tratamento convencional. Este estudo teve como objetivo avaliar a eficiência do sistema de zona de raiz em um tratamento de esgoto sanitário, para as condições climáticas de Goiânia-GO, Brasil. Para isso, foi construída uma estação de tratamento experimental na Escola de Engenharia Civil, da Universidade Federal de Goiás (EEC / UFG), consistindo de uma fossa séptica, filtro anaeróbio e três camaras biológica de zona de raiz, em paralelo, usando areia e brita zero e brita número um, respectivamente, como substrato. O sistema foi eficiente na remoção de DBO (98,5%), DQO (95,8%) e coliformes termotolerantes (99,99%)

Carotid intima-media thickness and flow-mediated dilation do not predict acute in-hospital outcomes in patients hospitalized with COVID-19

Studies have suggested a potential role of endothelial dysfunction and atherosclerosis in the pathophysiology of COVID-19. Herein, we tested whether brachial flow-mediated dilation (FMD) and carotid intima-media thickness (cIMT) measured upon hospital admission are associated with acute in-hospital outcomes in patients hospitalized with COVID-19. A total of 211 patients hospitalized with COVID-19 were submitted to assessments of FMD and mean and maximum cIMT (cIMTmean and cIMTmax) within the first 72 h of hospital admission. Study primary outcome was a composite of intensive care unit admission, mechanical ventilation, or death during the hospitalization. These outcomes were also considered independently. Thrombotic events were included as a secondary outcome. Odds ratios (ORs) and confidence intervals (CIs) were calculated using unadjusted and adjusted multivariable logistic regression models. Eighty-eight (42%) participants demonstrated at least one of the composite outcomes. cIMTmean and cIMTmax were predictors of mortality and thrombotic events in the univariate analysis (cIMTmean and mortality: unadjusted OR 12.71 [95% CI 1.71–94.48]; P = 0.014; cIMTmean and thrombotic events: unadjusted OR 11.94 [95% CI 1.64–86.79]; P = 0.015; cIMTmax and mortality: unadjusted OR 8.47 [95% CI 1.41–51.05]; P = 0.021; cIMTmax and thrombotic events: unadjusted OR 12.19 [95% CI 2.03–73.09]; P = 0.007). However, these associations were no longer present after adjustment for potential confounders (P > 0.05). In addition, FMD% was not associated with any outcome. In conclusion, cIMT and FMD are not independent predictors of clinical outcomes in patients hospitalized with COVID-19. These results suggest that subclinical atherosclerosis and endothelial dysfunction may not be the main drivers of COVID-19 complications in patients hospitalized with COVID-19

Electroconvulsive therapy use in adolescents: a systematic review

Abstract\ud \ud \ud \ud Background\ud \ud Considered as a moment of psychological vulnerability, adolescence is remarkably a risky period for the development of psychopathologies, when the choice of the correct therapeutic approach is crucial for achieving remission. One of the researched therapies in this case is electroconvulsive therapy (ECT). The present study reviews the recent and classical aspects regarding ECT use in adolescents.\ud \ud \ud \ud Methods\ud \ud Systematic review, performed in November 2012, conformed to the PRISMA statement.\ud \ud \ud \ud Results\ud \ud From the 212 retrieved articles, only 39 were included in the final sample. The reviewed studies bring indications of ECT use in adolescents, evaluate the efficiency of this therapy regarding remission, and explore the potential risks and complications of the procedure.\ud \ud \ud \ud Conclusions\ud \ud ECT use in adolescents is considered a highly efficient option for treating several psychiatric disorders, achieving high remission rates, and presenting few and relatively benign adverse effects. Risks can be mitigated by the correct use of the technique and are considered minimal when compared to the efficiency of ECT in treating psychopathologies
