Introduction: This study aimed to evaluate the use of sodium bicarbonate solution as an adjunct in the treatment of critically ill patients in an intensive care unit (ICU). Methods: A group of 76 patients were followed up, of which 44 received treatment with a sodium bicarbonate (NaHCO3) solution along with the conventional treatment, and 32 patients used only the conventional treatment. Results: In patients treated, there was an improvement in radiological findings, a decrease in opacity and bilateral consolidations, as well as reduced length of stay in the ICU, and mortality. Conclusion: The use of NaHCO3 solution as an adjunct in the treatment of COVID-19 improved prognosis compared to conventional treatment.

ResumoÉ importante identificar a qualidade da água, bem como a sua vulnerabilidade à atividade humana, tendo em vista a gestão dos recursos hídricos discutida globalmente e, em menor instância pela sazonalidade. O objetivo deste trabalho é avaliar os parâmetros de qualidade de água ao longo do igarapé São Francisco, correlacionando com as possíveis fontes poluidoras oriundas especialmente, das características antrópicas, e observar a variação sazonal desses parâmetros. A metodologia utilizada contemplou amostras de água coletadas na sub-superficie: pH, oxigênio dissolvido, condutividade elétrica, turbidez, sólidos totais, nitrogênio total, fósforo total, demanda bioquímica de oxigênio, demanda química de oxigênio e coliformes fecais. Análise de componentes principais foi utilizada para agrupar as estações de coleta, que não revelou tendência de agregação das estações de coletas em eixos nos dois períodos avaliados. As estações das pontes, onde possivelmente animais mortos são jogados, foram as mais impactadas no trecho avaliado. Palavras-chave: Gestão, recursos hídricos, Amazônia. ResumenEs importante identificar la calidad del agua, así como su vulnerabilidad a la actividad humana, con miras a la gestión de los recursos hídricos discutida globalmente y, en menor escala, por su estacionalidad. El objetivo de este estudio es evaluar los parámetros de calidad del agua a lo largo del igarapé San Francisco, en correlación con las posibles fuentes de contaminación procedentes, sobre todo, de las características antropogénicas, y observar la variación estacional de estos parámetros. La metodología utilizada ha considerado muestras de agua recogidas en la subsuperficie y se han evaluado los parámetros: pH, oxígeno disuelto, conductividad eléctrica, turbidez, sólidos totales, nitrógeno total, fósforo total, demanda bioquímica de oxígeno, demanda química de oxígeno y coliformes fecales. Se ha utilizado el análisis de componentes principales para agrupar las estaciones de muestreo, que no ha presentado tendencia a la agregación de las estaciones de recolección en ejes en los dos períodos evaluados. Las estaciones de los puentes, donde, posiblemente, los animales muertos son arrojados, fueron las más afectadas en el tramo evaluado. Palabras clave: gestión, recursos hídricos, Amazonia. AbstractIt is important to assess water quality, as well as its vulnerability to human activity, towards water resources management, globally discussed, and to a lesser extent, seasonally. The aim of this work is to evaluate the water quality parameters along the São Francisco River, correlating them to possible sources of pollution, especially derived from anthropization, and to observe seasonal variations in these parameters. Methods involved collecting subsurface water samples and assessing pH, dissolved oxygen, electrical conductivity, turbidity, total dissolved solids, total nitrogen, total phosphorus, biochemical oxygen demand, chemical oxygen demand and fecal coliform bacteria. Main components analysis was used for grouping sampling si...

This study aimed to evaluate the physicochemical composition, color and sensory acceptance of low-fat açaí and cupuaçu nectar, as well as changes in these parameters during storage. Nectars were prepared with açaí pulp previously defatted by centrifugation on a pilot scale. The study consisted of two steps. In the first step, the physicochemical characteristics, instrumental color, and sensory acceptance of the nectar prepared with low-fat açaí pulp were evaluated and compared with those of nectar prepared with full-fat açaí pulp. In the second step, titratable acidity, pH, soluble solids, anthocyanin content, instrumental color, and sensory acceptance of the low-fat açaí and cupuaçu nectar were evaluated for 6 months of storage at 25°C in the absence of light. The use of low-fat açaí pulp resulted in nectars with good overall acceptance, but with lower scores for color acceptance than those of the full-fat nectar. The low-fat nectar remained stable with respect to acidity, pH, and soluble solid content during storage for up to 180 days. However, there was degradation of anthocyanins, which had a negative impact on the product color and sensory acceptance over time. Under the conditions evaluated, the estimated product shelf life is up to 120 days.Keywords: Euterpe precatoria; nectar; low fat; sensory acceptance. Practical Application:This study proposes the formulation of a mixed fruit nectar using two raw materials from the Amazon region, açaí and cupuaçu, which is an interesting way to add value to this type of product. Additionally, it proposes the use of defatted açaí pulp, meeting the increasing consumers' preference for healthier foods containing functional compounds and that are low in fat.
