INTRODUCCIÓN: La pandemia de la COVID-19 ha generado nuevas barreras a la acción comunitaria en salud, pero también ha potenciado el desarrollo de iniciativas ciudadanas para responder colectivamente a la crisis social y sanitaria. En este contexto se crea el Observatorio de Salud Comunitaria y COVID-19 (OBSCOMCOVID), un espacio en el que personas vinculadas a la salud comunitaria se encuentran para reflexionar sobre las claves de la acción comunitaria en el contexto actual y desarrollar modelos de trabajo para el futuro...

Background: The prevalence of mental disorders among asylum seekers and refugees is elevated compared to the general population. The importance of post-migration living difficulties (PMLDs), stressors faced after displacement, has recently been recognized due to research demonstrating their moderating role of on mental health outcomes. Traditionally, PMLDs were investigated as count variables or latent variables, disregarding plausible interrelationships among them. Objectives: To use network analysis to investigate the associations among PMLDs...

BACKGROUND: This review investigates the use of social media at surgical conferences and possible effects of prepublication data release in surgical fields. Potential risks include patient harm by the preliminary application of research that lacks sufficient peer review, infringements on intellectual property, and loss of "research novelty." METHODS: A literature review of the current use of social media in dispersion of prepublication data was performed. Current submission guidelines for surgical conferences and journals were analyzed for data release embargos and social media use policies...
