Temperatura de secagem da casca da cebola para obtenção de chá

Objetivou-se realizar através do processo de secagem convectiva, o reaproveitamento do resíduo da cebola, especificamente a casca, para obtenção do pó, analisando os parâmetros físicos para posterior aplicação como chá. Os pós e chás foram submetidos às caracterizações físicas, químicas e físico-químicas. No tratamento estatístico, empregou-se o delineamento experimental de blocos inteiramente casualizados com 4 tratamentos e 3 repetições, os dados foram submetidos à análise de variância e a comparação de médias foi feita pelo teste de Tukey à 5% de probabilidade. A casca da cebola apresenta um maior teor de acidez em ácido pirúvico que as amostras secas (pó). As cascas da cebola apresentam uma luminosidade clara, assim como o chá em ambas as temperaturas, observando assim que a mesma não alterou esse parâmetro nas duas formas (casca e chá). A temperatura interferiu de forma satisfatória na casca para os valores de flavonoides, em contrapartida os valores de antocianinas, clorofilas e carotenoides foram insatisfatórios, para os chás, observou-se que os valores de flavonoides, carotenoides, clorofila e antocianinas tiveram um decréscimo e apresentaram uma variação nos valores com a mudança de temperatura. Por conseguinte, pode-se concluir que o uso de diferentes temperaturas de secagem torna-se inviável, sendo que a elaboração do chá com as cascas in natura proporciona a obtenção de teores mais elevados dos componentes

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat

Temperatura de secagem da casca da cebola para obtenção de chá

The objective of this work was to perform the reuse of the onion residue, specifically the bark, to obtain the powder through the convective drying process, analyzing the physical parameters for later application as tea. The powders and teas were submitted to the physical, chemical and physico-chemical characterization. In the statistical treatment, the experimental design of completely randomized blocks with 4 treatments and 3 replicates was used, the data were submitted to analysis of variance and the means comparison was done by the Tukey test at 5% probability. The onion peel has a higher acid content in pyruvic acid than the dry (powder) samples. The onion peels have a clear luminosity, as does tea at both temperatures, noting that it did not change this parameter in the two forms (bark and tea). The temperature interfered satisfactorily in the bark for the flavonoid values; in contrast, the anthocyanins, chlorophylls and carotenoids values were unsatisfactory; for the teas, it was observed that the values of flavonoids, carotenoids, chlorophyll and anthocyanins decreased and presented a change in the values with the change in temperature. Therefore, it can be concluded that the use of different drying temperatures becomes impracticable, and the preparation of the tea with the bark in natura provides the highest levels of the components.Objetivou-se realizar através do processo de secagem convectiva, o reaproveitamento do resíduo da cebola, especificamente a casca, para obtenção do pó, analisando os parâmetros físicos para posterior aplicação como chá.
