ABSTRACT
BACKGROUND: Web-based forums provide a space for communities of interest to exchange ideas and experiences. Nurse professionals used these forums during the COVID-19 pandemic to share their experiences and concerns. OBJECTIVE: The objective of this study was to examine the nurse-generated content to capture the evolution of nurses' work concerns during the COVID-19 pandemic. METHODS: We analyzed 14,060 posts related to the COVID-19 pandemic from March 2020 to April 2021. The data analysis stage included unsupervised machine learning and thematic qualitative analysis. We used an unsupervised machine learning approach, latent Dirichlet allocation, to identify salient topics in the collected posts. A human-in-the-loop analysis complemented the machine learning approach, categorizing topics into themes and subthemes. We developed insights into nurses' evolving perspectives based on temporal changes. RESULTS: We identified themes for biweekly periods and grouped them into 20 major themes based on the work concern inventory framework. Dominant work concerns varied throughout the study period. A detailed analysis of the patterns in how themes evolved over time enabled us to create narratives of work concerns. CONCLUSIONS: The analysis demonstrates that professional web-based forums capture nuanced details about nurses' work concerns and workplace stressors during the COVID-19 pandemic. Monitoring and assessment of web-based discussions could provide useful data for health care organizations to understand how their primary caregivers are affected by external pressures and internal managerial decisions and design more effective responses and planning during crises.
ABSTRACT
Debido a la frecuencia con que se presenta la conjuntivitis alérgica en nuestro medio, se buscó la forma de determinar la afección ocular más frecuente y la sensibilidad específica a diferentes aeroalergenos. Se publican los resultados de un estudio prospectivo longitudinal en 20 pacientes, que acudieron a la consulta externa de alergia e inmunología y oftalmología del Hospital Infantil de México Federico Gómez de mayo a julio de 1990, con diagnóstico de conjuntivitis alérgica, determinándose la afección ocular y la sensibilidad a diversos aeroalergenos por medio de pruebas cutáneas. Se encontró predominio del sexo masculino (17 vs 7), en la edad escolar, cuyos síntomas principales en orden de frecuencia fueron: plurito, ardor, lagrimeo y fotofobia. La conjuntivitis vernal en su variedad límbica y tarsal ocupó el primer lugar con 45 por ciento (9/20), siguiendo la conjuntivitis folicular en ocho pacientes y el resto con flictenular. Las pruebas cutáneas fueron negativas en ocho de los 20 pacientes. El alergeno principalmente relacionado fue el Amaranthus palmeri (siete pacientes), siguiendo el Rumex crispus y los ácaros del polvo casero (seis individuos).
