Estudios bibliométricos. Una opción para desarrollar investigación en cirugía y disciplinas afines

La bibliometría es la aplicación de métodos estadísticos para analizar libros, artículos y otras publicaciones, especialmente científicos. Muy relacionada con la cienciometría e informetría, al punto de superponerse y confundirse. La bibliometría se refiere al estudio de la dinámica de las disciplinas reflejado en la producción de su literatura. Incluye desde el registro de cambios en la producción de una disciplina académica a lo largo del tiempo y entre países, hasta el problema de la colección bibliotecaria. En este artículo se explicarán algunos conceptos históricos, definiciones y objetivos de la bibliometría; así como las Leyes de la bibliometría; los tipos de análisis e indicadores bibliométricos más utilizados; para terminar con algunos ejemplos de diferentes tipos de estudios bibliométricos publicados, para que el lector pueda formarse una idea general de lo que puede hacer en este campo, aplicando estas metodologías a disciplinas quirúrgicas y otras también. El objetivo de este manuscrito fue generar un documento de estudio respecto de la bibliometría como alternativa para desarrollar investigación en cirugía y disciplinas afines.

Bibliometrics is the application of statistical methods to analyze books, articles and other publications, especially scientific ones. Closely related to scientometrics and informetrics, to the point of overlapping and confusing. Bibliometrics refers to the study of the dynamics of the disciplines reflected in the production of their literature. It includes everything from the record of changes in the production of an academic discipline over time and between countries or regions, to the problem of the library collection. In this article some historical concepts, definitions and objectives of bibliometrics will be explained; as well as the Laws of bibliometrics; the types of analysis and bibliometric indicators most used; to finish with some examples of different types of published bibliometric studies, so that the reader can form a general idea of what he can do in this field, applying these methodologies to surgical disciplines and others as well. The aim of this manuscript was to generate a study document regarding bibliometrics as an alternative to develop research in surgery and related disciplines.

Bibliometric evaluation of Anais Brasileiros de Dermatologia (2013-2022)

Abstract The Anais Brasileiros de Dermatologia, published since 1925, is the most influential dermatological journal in Latin America, indexed in the main international bibliographic databases, and occupies the 50th position among the 70 dermatological journals indexed in the Journal of Citations Reports, in 2022. In this article, the authors present a critical analysis of its trajectory in the last decade and compare its main bibliometric indices with Brazilian medical and international dermatological journals. The journal showed consistent growth in different bibliometric indices, which indicates a successful editorial policy and greater visibility in the international scientific community, attracting foreign authors. The increases in citations received (4.1 ×) and in the Article Influence Score (2.9×) were more prominent than those of the main Brazilian medical and international dermatological journals. The success of Anais Brasileiros de Dermatologia in the international scientific scenario depends on an assertive editorial policy, on promptly publication of high-quality articles, and on institutional stimulus to encourage clinical research in dermatology.

Actualizando el sistema; capitalismo cognitivo y semiocapitalismo / Updating the System; Cognitive Capitalism and Semiocapitalism

El conocimiento en las sociedades digitalizadas se torna aceleradamente efímero, obsolescente y competitivo. Así, los roles de sus académicos se ven sometidos a una existencia precaria; se esfuerzan por acumular capital semiótico a través de factores de impacto ­fácilmente cuantificables­ que desdibujan el valor cualitativo de lo cognitivo. Es en esta trama que terminan inscribiéndose las universidades del siglo XXI; la mayéutica de Akádêmos comienza a desdibujarse tras la competitividad burocrático-empresarial del capitalismo cognitivo

Knowledge in digitized societies rapidly becomes ephemeral, obsolescent and competitive. Thus, the roles of its academics are subjected to a precarious existence; they strive to accumulate semiotic capital through impact factors ­ easily quantifiable ­ that blur the qualitative value of the cognitive. It is in this plot that the universities of the XXI century end up registering; Akádêmos's maieutics begins to blur behind the bureaucratic-business competitiveness of cognitive capitalism

Research trends within aneurysmal subarachnoid hemorrhage from 2017 to 2021: a bibliometric study.

Bibliometric analyses are a well-established strategy for understanding the dynamics of publications. Aneurysmal subarachnoid hemorrhage (aSAH) is a hot topic in neurology and neurosurgery research. To perform a bibliometric analysis of recent publications within aSAH. Articles addressing aSAH published between 2017 and 2021 were included and had their information extracted from Scopus. A total of 2177 articles were included. The mean number of citations was 6.18 (95%CI = 5.77-6.59). 2021 and 2020 were the most prolific years. World Neurosurgery (N = 389/2,177 articles; 17,87%) was the leading publisher, and American Journal of Neuroradiology had the highest number of citations per article (14.82) among journals with ≥ 10 publications. Primary research (N = 1624/2177) predominated, followed by case reports (N = 434/2,177). Among secondary studies, systematic reviews (N = 78/119) surpassed narrative reviews (N = 41/119). USA led the number of publications (N = 548/2,177 articles; 25.17%), followed by China (N = 358/2,177 articles; 16.44%). High-income countries had a higher number of publications (N = 1624/2177) and more citations per article (6.84) than middle-income countries (N = 553/2177 and 4.25, respectively). There were zero articles from low-income countries. European and North American institutions had the greatest research impact. There was an increase in the number of published articles in the last few years (2020 and 2021). Many studies had a low level of evidence, whereas interventional studies were uncommon.

Significado de la indexación de la Revista Peruana de Ginecología y Obstetricia a Scopus

La Revista Peruana de Ginecología y Obstetricia (RPGO) ha obtenido su inclusión en la importante base de datos Scopus. En una rápida recopilación de la publicación de la revista, se recuerda la dedicación editorial de sus seis editores, cuatro de los cuales acababan de presidir la Sociedad Peruana de Obstetricia y Ginecología (SPOG). Los momentos iniciales de trabajo editorial fueron realizados manualmente, en máquinas de escribir y visitando la imprenta continuamente, así como a los patrocinadores. El compromiso de los Comités Directivos de SPOG para financiar la publicación y distribución de los ejemplares permitió la gradual indexación a bases de datos locales, regionales e internacionales. Su internalización se amplió desde la publicación de la RPGO en el Open Journal Systems (OJS), sistema informático donde se publica los artículos con puntualidad, calidad, incluyendo sus características editoriales y la Información para los Autores. Ahora la publicación es solo virtual, en español e inglés, con visibilidad e impacto de los artículos desde el inicio de la RPGO en 1955. Con datos actualizados del OJS sobre la RPGO, el número de visitas mensuales a los resúmenes llegan hasta 10 mil y las descargas mensuales de artículos en formato PDF hasta más de 9 mil. Y, en el ámbito de revistas científicas de ginecoobstetricia de América Latina y España en Scopus, destaca el índice h de la RPGO por Google Scholar Metrics, como una de las mejores. Al presente, y frente a los desafíos futuros, la actividad de la RPGO ha sido fortalecida, estableciendo un equipo editorial y herramientas que permiten la ya iniciada profesionalización de los procesos de la actividad editorial.

The Peruvian Journal of Gynecology and Obstetrics (RPGO, for its acronym in Spanish) has obtained its inclusion in the important Scopus database. A quick review of the journal's publication recalls the editorial dedication of its six editors, four of whom had just recently chaired the Peruvian Society of Obstetrics and Gynecology (SPOG, for its acronym in Spanish). The initial editorial work was carried out manually, on typewriters and continuously visiting the printing press, as well as the sponsors. The commitment of the SPOG Steering Committees to finance the publication and distribution of the issues allowed the gradual indexing to local, regional and international databases. Its internalization was expanded since the publication of the RPGO in the Open Journal Systems (OJS), a computer system where articles are published with punctuality, quality, including their editorial characteristics and the Information for Authors. Now the publication is only virtual, in English and Spanish, with visibility and impact of the articles since the beginning of the RPGO in 1955. With updated OJS data on the RPGO, the number of monthly visits to the abstracts reaches up to 10 thousand and monthly downloads of articles in PDF format reach more than 9 thousand. And, in the field of obstetrics and gynecology scientific journals in Latin America and Spain in Scopus, the h index of the RPGO by Google Scholar Metrics stands out as one of the best. At present, and facing future challenges, the activity of the RPGO has been strengthened, establishing an editorial team and tools that allow the already initiated professionalization of the processes of the editorial activity.

Nutrition impact symptoms, sarcopenia, and malnutrition in hospitalized patients / Sintomas de impacto nutricional, sarcopenia e desnutrição em pacientes hospitalizados

INTRODUCTION: Nutrition Impact Symptoms (NIS) are common in hospitalized patients and can be aggravated in the presence of malnutrition. OBJECTIVE: To verify the presence of NIS and its association with sociodemographic and clinical variables, sarcopenia phenotype, and nutritional status of individuals hospitalized. METHODS: This is a cross-sectional study with hospitalized patients, of both sexes and ≥50 years old. Patient-Generated Subjective Global Assessment (PG-SGA), handgrip strength (HGS), gait speed GS), and anthropometric measurements were performed up to 48 hours after admission. NIS was obtained through PG-SGA and stratified into two groups: <3 and ≥3 symptoms. The chi-square test (χ2) was performed, and a 5% significance level was adopted. RESULTS: A total of 90 patients (65.4±9.67 years) were studied, with the majority of men (56.7%), older people (70.0%), married (68.9%), low economic class (72.2%), without work activity (70.5%), with two previous diseases (60.0%), overweight by body mass index (46.7%) and adequate adductor pollicis muscle thickness (83.3%). The most prevalent NIS were "dry mouth", "anorexia", and "smells sick" respectively 31.1%, 30.0%, and 16.7%. There was an association between NIS and SARC-F score (p=0.002), handgrip strength (p=0.016), the status of sarcopenia (p=0.020), PG-SGA (p<0.001), and economic status (p=0.020). CONCLUSION: The identification of NIS is common, and may infer negative nutritional status and functional performance of patients. The use of protocols to identify NIS during hospitalization should be considered to minimize the negative impact on nutritional status.

INTRODUÇÃO: Sintomas de impacto nutricional (SIN) são comuns em pacientes hospitalizados e estes podem ser agravados na presença da desnutrição. OBJETIVO: Verificar a presença de SIN e sua associação com as variáveis sociodemográficas, clínicas, fenótipo de sarcopenia e estado nutricional de indivíduos hospitalizados. MÉTODOS: Trata-se de estudo transversal com pacientes internados, de ambos os sexos e idade ≥ 50 anos. Realizou-se Avaliação Subjetiva Global produzida pelo Paciente (ASG-PPP), força de preensão palmar (FPP), velocidade de caminhada (VC) e medidas antropométricas até 48 horas da admissão. Os SIN foram obtidos por meio da ASG-PPP e compilados em <3 ou ≥3 sintomas. Realizou-se o teste de qui-quadrado (χ2). Adotou-se nível de significância de 5%. RESULTADOS: Um total de 90 pacientes (65,4±9,67 anos), sendo a maioria homem (56,7%), idoso (70,0%), casado (68,9%), classe econômica baixa (72,2%), sem atividade de trabalho (70,5%), com uma a duas doenças pregressas (60,0%), excesso de peso ao índice de massa corporal (46,7%) e adequada espessura do músculo adutor do polegar (83,3%). Os SIN "boca seca", "anorexia" e "cheiros enjoam" foram os mais prevalentes, respectivamente 31,1%, 30,0% e 16,7%. Houve associação dos SIN com as variáveis que compõem o fenótipo de sarcopenia: o escore SARC-F (p=0,002) e FPP (p=0,016), status de sarcopenia (p=0,020), ASG-PPP (p<0,001) e classe econômica (p=0,020). CONCLUSÃO: A identificação de SIN é comum, podendo inferir negativamente no estado nutricional e desempenho funcional dos pacientes. Considerar o uso de protocolos para identificação dos SIN durante a hospitalização a fim de minimizar a repercussão negativa no estado nutricional.

Impact factor JUMPS after the 2020 COVID-19 pandemic: a retrospective study in Dermatology journals.

BACKGROUND: The term "JUMPS" was used to describe the impact factor (IF) in an article published in PubMed in 2021, representing an increase of more than 40% of IF. AIMS: In this study, we aimed to compare the growth rate of IF JUMPS in Dermatology in the last 5 years, and particularly the effect of the 2020 COVID-19 pandemic. METHODS: This study evaluated the growth rate (JUMP) in IF from 2016 to 2020. We used the Friedman and Wilcoxon signed ranks tests. We classified JUMPS in negative growth rate; Q1 to Q4 quartiles; and journals with > 100%. A 76-100% growth rate was observed in five (7%) journals, and twelve journals (17%) depicted a 51-75% percentage of change. RESULTS: Several journals in the Dermatology category increased their IF by 50%. Repeated measures analyses showed a significant difference (p < .001). CONCLUSION: Although we found journals with growth rates in the four quartiles, no journals depicted negative growth rates nor > 100% growth. Knowing the growing trends in this category might supplement the assessment of target journals for authors looking to submit their works.

Do Brazilian medical journals reference Brazilian articles? A cross-sectional study.

Background: The quantity and quality of Brazilian scientific output increases decade by decade. However, there is a tendency to undervalue Brazilian journals, illustrated by the low number of citations compared with texts in international journals, with the tacit justification that foreign articles are of superior quality. Objectives: To investigate the differences in numbers of citations of Brazilian and international periodicals in three Brazilian journals from 2016 to 2020. Methods: All articles published in the Journal of the Brazilian College of Surgeons, in the Jornal Vascular Brasileiro, and in Acta Cirúrgica Brasileira from 2016 to 2020 were analyzed. The references of these studies were analyzed, summing the total number of citations and classifying them as published in Brazilian or foreign journals. Results: A total of 902 articles were analyzed, totaling 23,394 references, with a mean of 25.81 ± 8.59 references per article. Of these, 2,680 (11.45%) were Brazilian, equating to a mean of 2.95 ± 3.79 Brazilian references per article. Conclusions: It is necessary to improve appreciation of Brazilian periodicals, especially among Brazilian researchers and institutions responsible for science funding.

Métricas de impacto y evaluación de la ciencia / Impact metrics and science evaluation

RESUMEN Los científicos siempre buscaron formas de evaluar los resultados de las investigaciones para reconocer y premiar sus esfuerzos, y para apoyar decisiones en programas y políticas públicas. Las medidas o métricas de impacto de la ciencia se transformaron, en las últimas décadas, en el motor propulsor del ambiente académico. Investigadores, revistas científicas, bases de datos y casas editoriales, instituciones de investigación y agencias de financiación tienen su trabajo gobernado por el impacto de la investigación que producen, publican, indexan, promueven y financian. Se utilizan largamente indicadores bibliométricos para la evaluación de la producción científica, a pesar de la falta de relación inequívoca entre citas y calidad, impacto o mérito científico. Además, cuando se considera la innovación, característica inherente de la investigación científica, la relación es todavía más desconectada. En este artículo se describen los tipos principales de métricas utilizadas para evaluar la producción científica, sus características, potenciales y limitaciones.

ABSTRACT Scientists have always looked for ways to evaluate research results to recognize and reward their efforts, and to support decisions regarding programs and public policies. The metrics of scientific impact have become, in recent decades, the driving force behind the academic environment. The work of researchers, scientific journals, databases and publishers, research institutions, and funding agencies is driven by the impact of the research they produce, publish, index, promote and finance. Bibliometric indicators are widely used for the evaluation of scientific output, despite the lack of a clear relationship between citations and quality, impact, or scientific merit. Furthermore, the relationship is even less evident regarding innovation, which is an inherent characteristic of scientific research. This article describes the main types of metrics used to evaluate scientific output, as well as its features, potentials, and limitations.

The Author Impact Factor as a Metric to Evaluate the Impact of Neurosurgical Researchers.

OBJECTIVE: The objective of this study was to assess the Author Impact Factor (AIF) as a useful metric and as a complement to the h-index among neurosurgical researchers. METHODS: The 5-year AIF and h-index were compared among 3 groups of researchers: 1) the 100 most prolific of all time within general neurosurgical journals ("Experienced"), 2) the 100 most prolific during the 2015-2019 period within general neurosurgical journals ("Trending Group"), and 3) the 100 postgraduation year 7 neurosurgical residents with the highest h-index ("Amateur"). RESULTS: The Amateur group had a lower median h-index than the Experienced (6 vs. 55; P < 0.001) and Trending (6 vs. 43; P < 0.001) groups. The highest h-index of the Amateur group (24) was lower than the first quartile of the Experienced (46.25) and Trending (26.00) groups. The Amateur group had a lower median 5-year AIF than the Experienced (2.15 vs. 3.17; P < 0.001) and Trending (2.15 vs. 2.85; P = 0.02) groups. Unlike the h-index, the gap between the 5-year AIF distribution of the Amateur group and other groups was not profound. Although there was a positive correlation between the metrics in the 3 groups, they did not proxy for each other. For instance, while the h-index of some experienced authors that have not published recently was high, their AIFs were zero. Also, some Amateur authors published very impactful articles and had a high 5-year AIF. However, since their number of publications is inevitably low, their h-index were low. CONCLUSIONS: The AIF provides intuitive and complementary information to the h-index regarding the research output of neurosurgical authors.

Indicadores bibliométricos: impacto y altmetrics para una evaluación amplia y equitativa de las revistas científicas de Colombia / Bibliometrics Indicators: Impact and Altmetrics for an Extensive and Equitable Assessment of Colombian Scientific Journals / Indicadores bibliométricos: impacto e altmetria para uma avaliação ampla e equitativa das revistas científicas colombianas

La medición y análisis de la calidad de las publicaciones científicas es de fundamental importancia para evaluar el progreso e impacto de investigadores, grupos de investigación y revistas científicas en la comunidad académica y la sociedad (1,2). Tradicionalmente, la evaluación se encomendaba a pares de reconocida trayectoria, idoneidad y prestigio. Sin embargo, para eliminar subjetividades, desde hace varios años se ha recurrido a indicadores bibliométricos que propenden por una calificación mensurable, objetiva y multidimensional (1,3). Los indicadores bibliométricos (IB) pueden definirse como cuantificadores de información bibliográfica, disponible en documentos científicos y académicos, susceptible de ser analizada en términos de producción y consumo (1,2). Existe una variada tipología de IB (1,2) en función del objeto a examinar (investigador, revista o grupo de investigación) y que en algunos casos son transversales a este. Así, los indicadores personales (edad, sexo y antecedentes de los autores) solo aplican a investigadores o grupos, mientras que los de productividad e impacto aplican también a revistas. Para estas, el indicador de productividad (cantidad) y, aún más, el de impacto ("calidad") son rutinariamente empleados para clasificarlas y compararlas con el propósito, cada vez más controversial, de medir su pertinencia y relevancia académica y/o social (4).

Measuring and analyzing the quality of scientific publications is fundamentally important for assessing the progress and impact of researchers, research groups and scientific journals in the academic community and society (1,2). Traditionally, this assessment was entrusted to peers with a recognized track record, eligibility and prestige. However, bibliometric indicators have been used for several years to eliminate subjectivity, which aim at a measurable, objective and multi-dimensional qualification (1,3). Bibliometric indicators (BI) can be defined as quantifiers of the bibliographic information available in scientific and academic documents susceptible to being analyzed in terms of production and consumption (1,2). There is a typological variety of BI (1,2) based on the object to be examined (researcher, journal or research group) and, in some cases, they are cross-sectional to it. In this way, personal indicators (age, gender and background of the authors) only apply to researchers or groups, while productivity and impact also apply to journals. For journals, the productivity (quantity) and, more so, impact ("quality") indicators, are routinely used to classify journals and compare them, with the increasingly controversial purpose of measuring their academic and/or social pertinence and relevance (4).

A medição e análise da qualidade das publicações científicas é de fundamental importância para avaliar o progresso e o impacto de pesquisadores, grupos de pesquisa e revistas científicas na comunidade acadêmica e na sociedade (1,2). Tradicionalmente, a avaliação era confiada a pares de reconhecida trajetória, idoneidade e prestígio. No entanto, a fim de eliminar subjetividades, há vários anos são utilizados indicadores bibliométricos que visam uma qualificação mensurável, objetiva e multidimensional (1,3). Indicadores bibliométricos (IB) podem ser definidos como quantificadores de informações bibliográficas, disponíveis em documentos científicos e acadêmicos, passíveis de análise em termos de produção e consumo (1,2). Existe uma tipologia de IB variada (1,2) dependendo do objeto a ser examinado (pesquisador, periódico ou grupo de pesquisa) e que em alguns casos são transversais a ele. Assim, os indicadores pessoais (idade, sexo e formação dos autores) se aplicam apenas a pesquisadores ou grupos, enquanto os de produtividade e impacto também se aplicam a periódicos. Para estes, o indicador de produtividade (quantidade) e, mais ainda, o indicador de impacto ("qualidade") são rotineiramente utilizados para classificá-los e compará-los com o propósito cada vez mais controverso de medir sua pertinência e relevância acadêmica e/ou social (4).
