ABSTRACT BACKGROUND: A bibliometric analysis covering only the production of original studies or considering world production until 2022 has yet to be conducted. The creation and advancement of vaccines have also influenced research priorities, demonstrating the need for a new approach to this subject. OBJECTIVES: To analyze worldwide scientific production related to coronavirus disease 2019 (COVID-19) and the aged and to describe what has already been produced. DESIGN AND SETTING: Bibliometric analysis with a quantitative approach. METHOD: The search terms “COVID-19,” “SARS-CoV-2,” “Aged,” and “Elderly” were used to retrieve articles from the Web of Science database. A total of 684 articles were included in the analysis. Data were imported into RStudio Desktop Software and linked to R Software. The Bibliometrix R package and VOSviewer software were used for analysis. RESULTS: Most articles were published in 2020. These were produced by 4,937 authors and published in 379 journals. The keyword most used by the authors was “COVID-19.” Publications from 77 countries were obtained. China had the highest article production ranking, and Spain collaborated the most. The articles addressed the implications of the pandemic on the aged, the relationship between vaccination in the aged, and the implications for the disease itself. CONCLUSION: Further research should be conducted, mainly concerning vaccines and vaccination of the aged, owing to the need for and importance of immunization in this risk group, including assessing the long-term effects of vaccines.

ABSTRACT Objective: to understand the social representations elaborated by nursing students about the prevention of COVID-19. Method: exploratory-descriptive and qualitative research. Data were produced through interviews with 32 participants, conducted in the period from September 2021 to July 2022. The Study Setting was a public higher education institution, located in the northeastern region of Brazil. Data were processed using IRaMuTeQ software. Results: the genesis of the social representations of COVID-19 prevention pointed to two axes: Organization of ideas about COVID-19 prevention measures, and Efficiency, reliability and source of the information obtained. Final Considerations: the social representations showed the knowledge about the prevention measures of COVID-19, provided an opportunity to clarify the origin of the students’ knowledge and the specificities they consider important. It is hoped that this study can serve as a foundation for further research and/or interventions with nursing students.

RESUMEN Objetivo: Apreciar las representaciones sociales elaboradas por discentes de enfermería sobre la prevención del COVID-19. Método: investigación exploratoria-descriptiva y cualitativa. Los datos fueron producidos a través de entrevistas con 32 participantes, realizadas en el período de septiembre de 2021 a julio de 2022. El escenario del estudio fue una institución pública de enseñanza superior, localizada en la región nordeste de Brasil. Los datos fueron procesados utilizando el software IRaMuTeQ. Resultados: la génesis de las representaciones sociales de la prevención del COVID-19 apuntaba a dos ejes: Organización de ideas sobre las medidas de prevención del COVID-19; y Eficacia, fiabilidad y fuente de las informaciones obtenidas. Consideraciones Finales: Las representaciones sociales mostraron el conocimiento sobre las medidas de prevención del COVID-19, proporcionando una oportunidad para aclarar el origen del conocimiento de los estudiantes y las especificidades que ellos consideran importantes. Se espera que este estudio pueda servir de base para futuras investigaciones y/o intervenciones con estudiantes de enfermería.

Espera-se que esse estudo possa servir como alicerce para novas pesquisas e/ou intervenções com discentes de enfermagem.

ABSTRACT BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) infection is a worldwide concern given its presence even in non-hospitalized healthy individuals, such as university students. OBJECTIVE: To identify in the literature the prevalence of colonization by MRSA among healthcare students. DESIGN AND SETTING: Integrative review of the literature conducted in Universidade Federal do Piauí. METHOD: A search for primary studies was performed in the following databases: Medical Literature Analysis and Retrieval System on-line; Cumulative Index to Nursing and Allied Health Literature; Web of Science; Scopus; and LILACS. RESULTS: This review included 27 studies that demonstrated MRSA infection prevalence ranging from 0.0 to 15.3% among students. CONCLUSION: The prevalence of colonization of MRSA among healthcare students is high, and the nasal cavity was cited as an important reservoir location for these microorganisms.

ABSTRACT BACKGROUND: The pandemic of the new coronavirus has culminated in a scientific race to seek knowledge about this virus and its treatments, vaccines and preventive strategies, in order to reduce its impact on healthcare and economics worldwide. Hence, it is important to recognize the efforts of researchers who are at the forefront of investigations relating to the new coronavirus. OBJECTIVE: The present study was carried out with the aim of analyzing the world scientific production relating to COVID-19. DESIGN AND SETTING: Exploratory and descriptive bibliometric study conducted in the city of Teresina (PI), Brazil. METHOD: ISI Web of Knowledge/Web of Science (WOS) was chosen as the database. Data-gathering was carried out in May 2020. The data analysis was performed using the HistCiteTM software, version 9.8.24, and the VOSviewer bibliometric analysis software, version 1.6.8. RESULTS: 2,625 published papers that included descriptors within the scope of this investigation were identified. These articles were published in 859 different journals that are indexed in WOS, by 9,791 authors who were linked to 3,365 research institutions, located in 105 countries. CONCLUSION: Ascertaining scientific production through a bibliometric analysis is important in order to guide researchers on what has already been produced and what is being researched, so as to be able to address gaps in knowledge through future research.

ABSTRACT Objective: To discuss the correct use, indications for use, effectiveness and handling of the different types of mask, as well as suggest, based on scientific evidence and recommendations from health agencies, effective ways to increase the useful life of this product. Method: Narrative literature review using articles from the PubMed, Scopus and Web of Science databases, and recommendations from health agencies conducted in April 2020. Results: Protective respiratory devices (particulate respirators) can be reused if it is clean, dry and their layers and shape are intact. To increase the durability of surgical masks, the use of paper towels to absorb moisture is suggested. Cloth masks are recommended, as long as they are washed properly for reuse. Conclusion: Despite the scarce number of studies on the reuse of masks, given the expansion of COVID-19 and the worldwide shortage of this equipment, health professionals and the population must be constantly updated on the recommendations for use of these protective devices.

RESUMEN: Objetivo: discutir la forma correcta de utilización, indicaciones de uso, eficacia y manejo de cada tipo de mascarilla, además de sugerir, de conformidad con las evidencias científicas y recomendaciones de los órganos de salud, alternativas eficaces para aumentar la vida útil de este producto. Método: revisión narrativa con utilización de artículos provenientes de las bases de datos PubMed, Scopus e Web of Science, y recomendaciones de agencias de salud, realizada en abril de 2020. Resultados: las mascarillas de protección respiratoria pueden ser reutilizadas siempre que se encuentren limpias y secas, en tanto y en cuanto mantengan su integridad. Para aumentar la durabilidad de las mascarillas quirúrgicas, se sugiere su utilización con papel absorbente para absorber la humedad. Las mascarillas de tela son recomendables, siempre y cuando se laven adecuadamente para reutilización. Conclusión: aunque sean necesarios estudios acerca del reaprovechamiento de los barbijos, con la expansión del COVID-19 y la escasez mundial de este producto, es imprescindible que, tanto los profesionales de la salud como la población en general, se mantengan actualizados sobre sus recomendaciones de uso.
