Introducción: existe poca evidencia sobre el desarrollo de la investigación científica universitaria en el área odontológica en el Perú. Objetivo: determinar la producción científica y la percepción sobre la investigación en estudiantes de Odontología y su relación con el sexo, universidad de procedencia y año de estudio. Métodos: estudio multicéntrico, descriptivo y transversal en una muestra no probabilística de estudiantes de pregrado de siete facultades de Odontología del Perú, a quienes se les entregó un cuestionario estructurado para registrar sus datos generales y su percepción sobre la investigación y la producción científica. Se aplicaron las pruebas chi cuadrado y exacta de Fisher para relacionar las variables de estudio. Resultados: participaron 468 estudiantes con una edad media de 21,7 años (± 3,5), de los cuales 313 (66,9 %) fueron mujeres. La mayoría calificó como regular sus conocimientos en las tres áreas de investigación evaluadas. Se encontró una mayor producción de monografías en los estudiantes de la Sierra (p < 0,001) y mayor producción de reportes clínicos y tesis (p < 0,001) en los estudiantes de quinto y sexto años de estudio. Solo 11 (2,4 %) estudiantes publicaron artículos científicos, la mayoría de las universidades de la costa (p = 0,027) y pertenecientes al quinto y sexto años de estudio (p = 0,003). Conclusiones: la producción científica de los estudiantes de Odontología fue baja. Se encontró relación entre algunas variables de percepción de la investigación con la universidad de procedencia. También hubo relación entre la publicación científica y la elaboración de algunos trabajos académicos con la universidad de procedencia y el año de estudio.

Trends, characteristics, and impact of global scientific production on mental health of health workers in the context of coronavirus disease 2019 (COVID-19)

BACKGROUND

Healthcare workers are under significant constant stress as a result of the coronavirus disease 2019 (COVID-19) pandemic. The aim of this study, therefore, was to analyze bibliometrically the impact, trend, and characteristics of scientific production related to the mental health of health professionals during the COVID-19 pandemic.

MATERIALS AND METHODS

A bibliometric analysis of the scientific production on the mental health of health professionals and COVID-19 in Scopus from December 2019 to December 2021 was performed. An advanced search was designed using Boolean operators in Scopus and applied in April 2022. The metadata was entered into Microsoft Excel for the elaboration of the tables, SciVal to obtain the bibliometric indicators, and VosViewer to plot collaborative networks.

RESULTS

A total of 1393 manuscripts, 1007 of which met the eligibility criteria, were found on the mental health of health workers and COVID-19. The country with the highest academic production was the United States and Harvard University with 27 manuscripts as the most productive institution. The scientific journal with the highest scientific production was the International Journal of Environmental Research and Public Health with 138 manuscripts and 1580 citations, and the author with the most citations per publication was Carnnasi Claudia with 69.8.

CONCLUSION

The countries with the highest economic income occupy the first places in scientific production on the mental health of health workers during the COVID-19 pandemic, with the United States as the leader. There is a gap in the scientific knowledge on the mental health of healthcare workers during the COVID-19 pandemic in middle- and low-income countries.

Scientometric evaluation of trends and global characteristics of published research on occupational public health

The objective of this scientometric study was to assess the global trends and characteristics of published occupational health research from 2016 to 2020. The SciVal tool (Elsevier) was used to perform the corresponding bibliometric analyses such as the Field-Weighted Citation Impact (FWCI), Source Normalized Impact per Paper (SNIP), CiteScore, and SCImago Journal Rank (SJR). Most of the manuscripts (46.5%) had national collaboration, with an average of 6.1 citations per paper. However, only 71 manuscripts (5.4%) presented single authorship (without collaboration). It was found that 486 manuscripts related to occupational health were published in Q2 journals (top 26-50%). Scientific publications on occupational health have increased remarkably worldwide, especially in Europe, and have mainly been published in Q1 and Q2 journals with a total of 292 and 289 scientific manuscripts in 2019 and 2020, respectively.

Scholarly Output in Peruvian National Dentistry according to Gender Disparity: A 10-Year Bibliometric Study

Objective. To evaluate Peruvian scientific publications in dentistry according to sex disparity (2011-2020). Methods. This was a retrospective bibliometric study. The unit of analysis was made up of Peruvian dentistry publications indexed in the Scopus database during the last 10 years. Records with metadata (410) corresponding to the period 2011-2020 were downloaded and standardized and refined by analyzing the metadata. The search strategy was developed based on the individual profiles of each Peruvian institution that has a dental school or college. It was evaluated according to the AF-ID of each institution in the Scopus database. In addition, the information provided by the Scopus SciVal tool was used. Finally, publications, impact, and collaboration indicators were used, such as total number per document, per author, average of citations, $h$ -index, collaboration rate, number of institutions, the Source Normalized Impact per Paper indicator, the CiteScore, and the Scopus Field-Weighted Citation Impact. Results. The greatest increase was evident in 2018, with 2019 and 2020 being the maximum peak of scientific publication growth. However, sustained growth has not been evidenced in relation to the female sex. The analysis of coauthorship by the authors revealed four large clusters, of which the first three were represented by male researchers, such as Arriola-Guillen L., Mayta-Tovalino F., and Mendoza-Azpur G., and one by a female, Guerrero María E. Evaluating the national scientific publication in dentistry according to the CiteScore, it was found that most of the publications (145) from Peru were published in Q4 journals, although 90 manuscripts were published in Q1 journals. Conclusions. The Peruvian national dental publication in the last 10 years was mainly supported by male dentists, which invites us to reflect on the need to equalize opportunities so that female researchers can also reduce these gaps.
