Bibliometric analysis of peer-reviewed literature on perinatal depression in Mexico / Análisis bibliométrico de la literatura revisada por pares sobre depresión perinatal en México

Abstract Background Perinatal depression (PND) is a clinical disease developed in any stage during the pregnancy and postpartum period with serious health and economic implications. Objective The aim of this work was to analyze via bibliometrics indicators Mexico's production on PND to provide a view of the academic landscape and a comprehensive reference for subsequent research in the country. Method The Scopus and Web of Science (WoS) databases were used to perform a search for peer reviewed papers related to PND in México. The search was made following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The extracted data were processed with VOS Viewer to examine link strength and clusters associations of diverse bibliometrics variables. Results A total of 132 records were retrieved and we included 70 studies in the bibliometric analysis after application of the exclusion criteria. The authors with more papers were Navarrete L., and Asunción Lara M. The institutions with more papers were the National Institute of Perinatology, Ramón de la Fuente National Institute of Psychiatry, and National Institute of Public Health of Mexico. A diminution of the research considered in PND is observed in the last two years. Four keyword clusters were identified related to PND: symptoms, prevalence, pregnancy. Discussion and conclusion The scarce literature concerning PND in Mexico compared with other countries could be due the limited collaboration between the health institutes. An urgent need to increase research on PND in Mexico is evident to be applicable in the management of resources in the healthcare system.

Background: South Africa reported a new variant of SARS-CoV-2, named 'Omicron,' to the World Health Or-ganization on November 24, 2021. Scientometric analysis quantify all currently available written communica-tion, the authors of that communication, and their citation analysis. The study's goal was to use the Scopus and Web of Science databases to look at the research metrics of Omicron publications published between Jan-uary 1965 and March 2020. Methods:All scientific research outputs with the word 'Omicron' in the title were retrieved from the Web of Science (January 1965 to March 2022) and Scopus (January 1896 to March 2022) databases on April 10, 2022. The data was analyzed based on year-wise publications; leading authors; predominant journals in publishing, highly cited articles with citations; type of publications; subject classification, frequently used keywords, geo-graphical distribution of publication, language, and more contributed institutions. Results: There were 1229 research outputs for WoS and 655 from Scopus. The number of publications for WoS increased from 22 in 1965 to 265 in 2022, while Scopus increased from 1 in 1896 to 356 in 2022. Both the databases identified the author Yuen KY as the highest contributor; Journal of Virology and Nature as the predominant journals; the Lancet as highly cited journal; majority as original articles; frequently used key-words as 'SARS-CoV-2'; the United States of America as the most productive country; majority publication in English. The publications were mainly on the subjects Chemistry and Medicine by WoS and Scopus, respec-tively. The most productive institute was the ‘University of California Systems’ by WoS and the ‘University of Hong Kong’ by Scopus. Conclusion: The term 'Omicron' first appeared in the domain of Chemistry in the late 18th century. The growth pattern of publication was not consistent. The above research metrics will be helpful to researchers in the coming days.

Las limitaciones de Scopus como fuente de indicadores: Buscando una visibilidad integral para revistas argentinas en ciencias sociales / Limitations of Scopus as a source of indicators: In search for a more comprehensive understanding of the visibility of Argentinian social science journals

Resumen En este trabajo se avanza en la definición de un conjunto de indicadores para medir la visibilidad de las revistas científicas de ciencias sociales de manera integral. Para esto, se considera el uso de fuentes diversas que permitan conocer la citación, la accesibilidad y los alcances de las publicaciones. Se toman como muestra 11 revistas de ciencias sociales editadas en Argentina incluidas en el SCImago Journal & Country Rank. Se analizan sus posiciones en el ranking y el número de citas de esta base y se lo compara con datos recogidos en Google Scholar utilizando la herramienta Publish or Perish. Además, se sistematiza información acerca de su accesibilidad e indicadores de uso y métricas alternativas de sus propios portales, de SciELO, Redalyc y de la base de datos Dimensions. Se pone en evidencia la parcialidad del impacto medido desde Scopus para este grupo de revistas y se demuestra que, al combinar las fuentes, se amplían y diversifican los datos de visibilidad. Para finalizar, se proponen una serie de indicadores básicos de visibilidad integral a partir de las fuentes disponibles que permiten a los gestores de revistas ofrecer datos más certeros de la citación y usos de las revistas y sus artículos.

Abstract This work seeks proposes a group of indicators that can be used to understand the visibility of social science journals in a more comprehensive way. To this end, the use of various sources of data pertaining to citation, accessibility, and reach are considered. A sample of 11 social science journals published in Argentina and indexed in Scimago Journal & Country Rank is used. The ranking and number of citations found in Scopus are analyzed and compared against data obtained from Google Scholar using the Publish or Perish tool. In addition, data regarding the accessibility and use, as well as alternative metrics, are collected from SciELO, Redalyc, and Dimensions and systematized. The analysis highlights the limited ways in which impact is measured using Scopus data and shows that, by combining data from additional sources, new dimensions of visibility are made apparent. The article concludes with a proposal for a new set of comprehensive visibility indicators that rely on freely available data and allow journal managers and editors to offer a more complete picture of the citational impact and use of their journals and articles.

Bases de datos con ánimo de lucro y la mercantilización de las publicaciones científicas. Colombia, una vía de entrada / Data bases for profit and the commercialization of scientific publications. colombia, a reference case

RESUMEN En el marco del presente ensayo, esta discusión tiene como propósito poner en evidencia el embargo que ha venido sufriendo las producciones académica y la científica, en el ámbito de las publicaciones escritas, por parte de bases de datos propiedad de consorcios comerciales transnacionales, cuya misión corporativa ha estado orientada fundamentalmente al lucro. En este proceso de embargo, quienes investigan han perdido el dominio y la soberanía sobre su producción intelectual. La investigación se ha visto reducida a criterios de gestión, y la comunicación del conocimiento ha quedado restringida por las transacciones monetarias y la mercadotecnia empresarial.

ABSTRACT Within the framework of this essay, the purpose of this discussion is to highlight the embargo that academic and scientific productions have been suffering, in the field of written publications, by databases owned by transnational commercial consortia, whose corporate mission has been fundamentally oriented to profit. In this embargo process, researchers have lost control and sovereignty over their intellectual production. Research has been reduced to management criteria, and the communication of knowledge has been restricted by monetary transactions and corporate marketing.

Conclusões: a área da saúde precisa aproximar-se cada vez mais do desenvolvimento de pesquisas associadas às redes sociais, pois isso possibilitaria uma intervenção viável e rápida na obtenção de respostas, além de ser uma ferramenta de baixo custo e bastante promissora para a coleta de dados.

Un estudio sobre la implementación del método Delphi en publicaciones de ciencias médicas indexadas en Scopus / A study on the implementation of the Delphi method in publications of medical indexing sciences in Scopus

Introducción: El método Delphi ha sido aplicado en varias investigaciones del campo de las ciencias médicas cubanas. Con frecuencia, este método sigue el enfoque clásico de la búsqueda de consenso, aunque existen numerosas variantes en el campo de la prospectiva. Objetivo: Caracterizar el uso del método Delphi, en busca de un patrón que facilite la identificación de posibles tendencias de desarrollo en el ámbito de las ciencias médicas. Métodos: Se utilizaron técnicas cienciométricas para procesar una matriz de datos obtenida de Scopus. La lógica de búsqueda se apoyó en la aparición de los términos más frecuentes "Delphi method", "Delphi study", o "Delphi technique" en los títulos, resúmenes y palabras claves. Las variables objeto de estudio fueron la productividad científica, la distribución por ramas del conocimiento, el impacto por índice de citas, las tendencias investigativas y las redes de colaboración. Resultados: De 10341 documentos, 5282 fueron relacionados con las ciencias médicas (33,26 por ciento), y 29 son de autores cubanos. El crecimiento diacrónico fue exponencial y el número de citas se concentró en un número reducido de documentos. Predominó el Delphi clásico enfocado hacia el consenso, en detrimento de otras variantes más flexibles descritas en la literatura. Las redes de colaboración indicaron la existencia de 15 colegios invisibles por clústeres de co-autoría. Conclusiones: El uso del método Delphi en investigaciones médicas cubanas no es una eventualidad local, sino que responde a una tendencia mundial acrecentada durante los últimos años(AU)

Introduction: The Delphi method has been applied to several investigations in the field of Cuban medical sciences. Frequently, this method follows the classical approach of seeking consensus, although there are numerous variants in the field of prospective. Objective: To characterize the use of the Delphi method, in search of a pattern that facilitates identifying possible development trends in the field of medical sciences. Methods: We used scientometric techniques to process a data matrix obtained from Scopus. The search logic is based on the appearance of the most frequent terms Delphi method, Delphi study, or Delphi technique in titles, abstracts and keywords. The variables studied are scientific productivity, distribution by branches of knowledge, impact by citation index, research trends, and collaboration networks. Results: From 10 341 documents, 5282 are related to medical sciences (33.26 percent), and 29 are by Cuban authors. The diachronic growth is exponential and the number of citations is concentrated in a reduced number of documents. The classic Delphi focused on consensus predominates over other more flexible variants described in the literature which are decreasing. Collaboration networks indicate the existence of 15 invisible colleges by clusters of co-authorship. Conclusions: The use of the Delphi method in Cuban medical research is not a local event, but responds to a global trend that has increased during the last years(AU)

Comparación entre Web of Science y Scopus: estudio bibliométrico de las revistas de anatomía y morfología / Comparison between Web of Science and Scopus: bibliometric study of anatomy and morphology journals

El objetivo de este trabajo es comparar los indicadores bibliométricos básicos del área de anatomía y morfología dentro de las bases de datos de Web of Science (en adelante WoS) y Scopus. La metodología llevada a cabo se basa en una búsqueda bibliométrica realizada en Web of Knowledge y Scopus. La muestra la conforman el conjunto de revistas indexadas en ambas bases de datos del área citada. Los resultados indican que el número de revistas fue mayor en Scopus que en WoS (42 vs. 21). El índice citas/artículo global es mayor en Scopus. Solamente hay dos revistas que permiten publicar sus artículos en un idioma diferente al inglés en WoS y tres en Scopus. En WoS, los valores de factor de impacto y del índice h tienen una correlación de 0,17, mientras que en la base de datos Scopus los valores de correlación entre el factor de impacto y del índice h, son muy superiores, tiene una correlación de 0,79. La mayoría de revistas están editadas en países anglosajones. Las conclusiones del estudio nos llevan a resaltar que existe un mayor número de revistas y citas en Scopus comparado con WoS. La utilización del factor de impacto para la evaluación de una revista parece ser un indicador más conveniente a corto plazo, siendo el índice h un indicador que refleja la influencia a largo plazo de una publicación y posiblemente refleja mejor la categoría científica de ésta. En la actualidad es conveniente aconsejar el uso de varios índices en la evaluación de la calidad de las revistas.

The aim of this study is to compare the basic bibliometric indicators in the area of anatomy and morphology inside the databases Web of Science and Scopus. The methodology carried out is based on a bibliometric search conducted in Scopus and Web of Knowledge. The sample comprises the set of journals indexed in both databases of the cited field. The results indicate that the number of journals was higher in Scopus than WoS (42 vs. 21). The overall reference / article index is higher in Scopus. There are only two journals that allow publication of papers in a language other than English, one in WoS and three in Scopus. In WoS, the impact factor value and h-index has a correlation of 0.17, while the Scopus database correlation values between the impact factor and h-index, are far superior, it has a correlation 0.79. Most journals are published in English-speaking countries. These findings lead us to highlight that there are a greater number of citations in Scopus journals compared with WoS. The use of the impact factor to evaluate a journal seems to be a more convenient short-term indicator, the h index is an indicator that reflects the long-term influence of a publication and could also better determine the article´s scientific category. Currently, the use of various indices is advisable in evaluating the quality of journals.
