Objetivo: Determinar los factores sociodemográficos asociados a depresión, estrés y ansiedad en el personal de salud del Hospital Nacional Sergio E. Bernales durante la pandemia COVID-19, Lima 2021. Materiales y Métodos: El tipo de estudio fue observacional, analítico, prospectivo, transversal, correlacional. Se obtuvo una muestra de 195 participantes conformado por el personal de salud del HNSEB, se utilizó como instrumento la encuesta sobre factores sociodemográficos y el DASS-21 que evalúa niveles de depresión, estrés y ansiedad. Resultados: La edad, sexo, estado civil, profesión, enfermedad crónica si están asociados a la depresión, mientras que el área de trabajo y la pérdida de una persona cercana no lo está. El sexo y estado civil si guardan asociación con el estrés, no se encontró asociación con la edad, profesión, área de trabajo, enfermedad crónica, y p�...

The antioxidant capacity in fruit extracts of (Muehlembeckia volcanica) has been characterized, quantified and determined for which the anthocyanin pigments were extracted with 0.01% acidified methanol HCl, filtered, concentrated, centrifuged and fed to a known volume for later analysis. In the extract the content of total anthocyanin’s (CAT) was evaluated by the differential pH method, total polyphenols (PFT) by the Folin-Ciocalteu method and its antioxidant capacity by the TEAC DPPH Method. Extracts characterized by UV-Vis spectrophotometry have maximum absorbance values ​​at 520 nm that correspond to established anthocyanin structures, in the same way by FTIR-ATR spectroscopy strong absorption signals are observed at different vibration frequency values which correspond to anthocyanin functional groups. The HPLC chromatograms of the extract belong to anthocyanin’s delfinidine ...
