ABSTRACT
Bioactive compounds, such as phenolic compounds, are phytochemicals found in significant amounts in cereals and pseudocereals and are usually evaluated by spectrophotometric (UV-VIS), HPLC, and LC-MS techniques. However, their bioavailability in grains is quite limited. This restriction on bioavailability and bioaccessibility occurs because they are in conjugated polymeric forms. Additionally, they can be linked through chemical esterification and etherification to macro components. Techniques such as thermoplastic extrusion, germination, fermentation, and hydrolysis have been widely studied to release phenolic compounds in favor of their bioavailability and bioaccessibility, minimizing the loss of these thermosensitive components during processing. The increased availability of phenolic compounds increases the antioxidant capacity and favor their documented health promoting.
ABSTRACT
OBJECTIVE: To evaluate the occupational safety and health management of COVID-19 at a company in the Peruvian fishing sector Methods: The independent variable was occupational safety and health management, defined as the implementation of preventive and control measures in response to COVID-19. The dependent variable was defined as the number of detected COVID-19 cases and test positivity rate. We used a pre- (implementation phase) and post-test (following the implementation phase) study design. We performed a non-parametric inferential analysis to identify any significant pre- and post-test differences and any associations between the variables. RESULTS: The company initiated a strategy to detect positive cases through the use of serological tests. During the first stage, 2329 tests were conducted, yielding a positivity rate of 71%. Once prevention and control actions were implemented, the positivity rate in August 2020 had decreased to 15.65%,, a statistically significant decrease (p<0.05), as well as its relationship to the measures implemented. CONCLUSIONS: This occupational safety and health intervention significantly reduced the number of COVID-19 cases and positivity rate in this group of workers in the Peruvian fishing sector.
Objetivo: Evaluar la gestión de seguridad y salud en el trabajo de una empresa del sector pesquero peruano frente al Covid-19 Métodos: La variable independiente fue la gestión de seguridad y salud en el trabajo respecto a la implementación de acciones preventivas y de control frente al Covid-19. La variable dependiente se midió a través del número de casos detectados y la tasa de positividad de Covid-19. Se utilizó un diseño preexperimental con una preprueba, durante la implementación en proceso y una post prueba, con información recopilada al finalizar las acciones preventivas y de control. Se realizó un análisis inferencial no paramétrico para establecer diferencias significativas entre la preprueba y la post prueba y el grado de asociación entre las variables. Resultados: La empresa inició una estrategia de detección de casos positivos a través del uso de pruebas serológicas. Durante la primera etapa, se realizaron 2329 pruebas que arrojaron un 71% de positividad. Una vez que se implementaron las acciones de prevención y control la tasa de positividad se redujo a un 15.65% durante agosto del 2020. Las pruebas inferenciales mostraron un nivel de significación (p<0.05) en la reducción obtenida, así como en la relación de esta con las medidas adoptadas. Conclusiones: Una adecuada gestión de seguridad y salud en el trabajo frente al Covid-19 redujo de manera significativa el número de casos detectados y la tasa de positividad del Covid-19 en trabajadores del sector pesquero peruano.
