Introducción: las condiciones de trabajo en el ámbito sanitario impactan la salud mental de los trabajadores y afecta su bienestar. Para poder realizar una medición oportuna en el Perú, se requiere contar con instrumentos validados y fáciles de administrar. Objetivo: adaptar y validar el cuestionario de salud general (GHQ-12) en trabajadores de salud del Perú. Métodos: se realizó un estudio de tipo instrumental en el que participaron 432 trabajadores del sistema sanitario peruano, seleccionados por muestreo aleatorio estratificado. El proceso incluyó una evaluación del contenido por parte de jueces y una prueba piloto. La validez de constructo se evaluó mediante un análisis factorial exploratorio. El número de factores se definió con el análisis paralelo de Horn y el ajuste con análisis factorial confirmatorio, que tuvo en cuenta distintos métodos de estimación. Se analizó la confiabilidad, la validez discriminativa, correlación y predictiva. Resultados: se confirmó una versión del cuestionario con doce ítems agrupados en dos factores que explicaron el 58,68 % de la varianza total. El modelo evidencia mejores índices de bondad de ajuste de manera independiente al método de estimación empleado. Los ítems discriminan de manera adecuada, al igual que el cuestionario, según género y profesión. La validez de correlación y predictiva fueron satisfactorias. La consistencia interna global con el omega de McDonald fue adecuada (ω = 0,853), así como el alfa ordinal para disforia general (0,919) y disfunción social (0,828). Conclusiones: se reportan sólidas evidencias de validez de constructo y confiabilidad del GHQ-12. Al ser la versión peruana, se recomienda usarlo para evaluar el estado mental de los trabajadores de salud.
Petroselinum crispum (Mill) Fuss is an aromatic plant belonging to the Apiaceae family and used in gastronomy as a spice. Several studies have been developed in leaves but studies are limited in seeds, especially the essential oils obtained from seeds. The aim of this study was to determine the phytochemical profile of the volatile compounds of this essential oil by gas-chromatography–mass spectrometry (GC-MS) in order to evaluate its phytotoxic activity on Lactuca sativa seeds and to carry out an in silico analysis on the target enzyme of the herbicide glyphosate 5-enolpyruvylshikimate 3-phosphate synthase (EPSP). The essential oil was obtained by steam distillation for two hours and then was injected into a GC-MS, the phytotoxic assay was carried out on Lactuca seeds and the in silico evaluation on the EPSP synthase focused on the volatile compounds similar to glyphosate, docking analysis, and molecular dynamics to establish the protein–ligand stability of the most active molecule. The chromatographic analysis revealed 47 compounds, predominated by three compounds with the most abundant percentage in the total content (1,3,8-ρ-menthatriene (22.59%); apiole (22.41%); and β-phellandrene (15.02%)). The phytotoxic activity demonstrated that the essential oil had a high activity at 5% against L. sativa seed germination, inhibition of root length, and hypocotyl length, which is comparable to 2% glyphosate. The molecular docking on EPSP synthase revealed that trans-p-menth-6-en-2,8-diol had a high affinity with the enzyme EPSP synthase and a better stability during the molecular dynamic. According to the results, the essential oil of P. crispum seeds presented a phytotoxic activity and might be useful as a bioherbicide agent against weeds.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
