RESUMO

Microplastics, capable of absorbing persistent organic compounds, heavy metals, and emerging pollutants, are of global concern due to their potential to alter the behavior and metabolism of biota. In Latin America, the Pacific Alliance, comprising Mexico, Colombia, Peru, and Chile, stands out for its biological wealth and productive ecosystems, which account for 37% of the region's gross domestic product. The leaders of these countries expressed their concern about microplastic pollution and pledged to take joint action. We conducted an analysis of the scientific production of these countries and the collaborations of their researchers, focused on the period 2015-2023, using Scopus and SCImago. We observed that marine-coastal/wetland ecosystems are the most studied, with a focus on fish, and that Mexico leads in publications, followed by Colombia, Peru, and Chile. In addition, we note the absence of an inter-institutional group dedicated to microplastics research in these countries. We recommend promoting collaboration between academic institutions specialized in microplastic research and government agencies dedicated to the promotion of science and technology in the countries belonging to the Pacific Alliance.

RESUMO

Se han propuesto varios indicadores bibliométricos para evaluar el desempeño de los investigadores a nivel mundial, uno de ellos es el índice h que considera tanto el número de publicaciones como las citas recibidas, y posiciona a los investigadores según una escala propuesta por Jorge Hirsch en investigador exitoso (h=20), excelentes científicos (h=40) y como un individuo singular (h=60). El objetivo del estudio fue evaluar el desempeño de investigadores paraguayos de las disciplinas de medicina, bioquímica y biología a través del Índice h de Hirsch comparando Google Scholar y Scopus. Es un estudio descriptivo con enfoque cuantitativo. Se incluyeron todos los investigadores paraguayos de las áreas mencionadas cuyos datos se encontraban disponibles en Google Scholar y/o Scopus. Para la identificación inicial de los investigadores se recurrió al cvpy disponible en la página web del CONACYT, Paraguay, y se utilizó el software Publish or Perish. Se identificaron 158 investigadores, de ellos ocho están posicionados en la escala de Hirsch. El 13 % de los investigadores tuvieron un índice h igual o mayor a 10 en Google Scholar y Scopus, correspondiendo al área de medicina el valor más alto, 54 en Google Scholar y 47 en Scopus. El desempeño de los investigadores por el índice h está por debajo de la región. Existe necesidad de mayor inversión en las revistas científicas nacionales para su indexación en bases de datos que colecciona revistas de mayor impacto.

Several bibliometric indicators have been proposed to evaluate the performance of researchers worldwide, one of them is the h index that takes into account both the number of publications and citations, and ranks researchers according to a scale proposed by Jorge Hirsch in successful researcher (h=20), excellent scientists (h=40) and as a singular individual (h=60). The objective of the study was to evaluate the performance of Paraguayan researchers from the disciplines of medicine, biochemistry and biology through the Hirsch h-Index comparing Google Scholar and Scopus. All Paraguayan researchers from the aforementioned areas whose data were available in Google Scholar and/or Scopus were included. It is a descriptive study with a quantitative approach. For the initial identification of the researchers, the cvpy available on the CONACYT, Paraguay website was used, and the Publish or Perish software was used. 158 researchers were identified, eight of them are positioned on the Hirsch scale. 13% of researchers had an h index equal to or greater than 10 in Google Scholar and Scopus, with the highest value corresponding to the area of ​​medicine, 54 in Google Scholar and 47 in Scopus. Researchers mostly publish in low-impact national journals with few citations. The performance of the researchers by the h-index is below the region. There is a need for greater investment in national scientific journals for their indexing in databases that collect journals with higher impact.

RESUMO

Decreased estrogen levels in menopause are associated with anthropometric, metabolic, and inflammatory impairments, predisposing women to cardiometabolic risk factors such as diabetes. Menopause and type two diabetes (DM2) are marked by altered heat shock response (HSR), shown by decreased expression of the 70-kDa heat shock protein in the intracellular milieu (iHSP70). While iHSP70 plays an anti-inflammatory role, extracellular HSP70 (eHSP70) may mediate pro-inflammatory pathways and has been associated with insulin resistance in DM2. Considering the roles of these proteins according to localization, the eHSP70-to-iHSP70 ratio (H-index) has been proposed as a biomarker for HSR. We, therefore, evaluated whether this biomarker is associated with glycemic and inflammatory status in postmenopausal women. In this transversal study, 36 postmenopausal women were grouped according to fasting glycemia status as either the control group (normoglycemic, ≤ 99 mg/dL) or DM2 (prediabetic and diabetic, glycemia ≥ 100 mg/dL). DM2 group showed higher triglyceride/glucose (TyG) index and plasma atherogenic index (PAI), both of which are indicators of cardiometabolic risk. In addition, we found that the eHSP70-to-iHSP70 ratio (plasma/peripheral blood mononuclear cells-PBMC ratio) was higher in the DM2 group, compared with the control group. Furthermore, blood leukocyte and glycemia levels were positively correlated with the eHSP70-to-iHSP70 ratio in women that presented H-index values above 1.0 (a.u.). Taken together, our results highlight the eHSP70-to-iHSP70 ratio as a biomarker of altered HSR in DM2 postmenopausal women.

RESUMO

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.

RESUMO

Emotions are considered a fundamental aspect of sport scenarios, and within sports, consumer behavior is a very popular area of research in the sport management field. Thus, in recent years, there has been a growing interest for sport managers regarding the role that emotions play in sport consumer behavior. Thus, the aim of this paper is to provide an overview of the academic research on emotions in the sport management field using two techniques: a bibliometric performance analysis and a graphic mapping of the references in this field. This analysis focuses on authors, journals, papers, institutions and countries. Bibliometric indicators including the h-index measure, productivity and the number of citations were used to perform the performance analysis. Then, VOSviewer software was used to perform co-citation, bibliographic coupling and co-occurrence of keyword analysis (mapping analysis). The results of both types of analysis are consistent, with the United States being the most influential country in emotions in sport management research because the main authors and institutions in this research field belong to this country. The overall results indicate that the literature on this research topic has grown significantly in recent years in all scientific disciplines; however, the research topic is incipient, and therefore, the number of articles is still limited. Thus, this research presents the key aspects in the topic of emotions in sport management that could be helpful for researchers and policy makers in the field of sport management to make future decisions.

RESUMO

BACKGROUND: Contributions from Latin America to the global literature are scarce; until 2011, spine surgeons had published 320 articles in indexed journals. METHODS: This systematic review evaluates the scientific production of the Mexican Association of Spine Surgeons (Asociación Mexicana de Cirujanos de Columna-AMCICO) from its inception in 1998 to 2018 with the PRISMA statement using PubMed and Google Scholar search engines. The inclusion criteria were spine-related articles in indexed journals providing any (or no) level of evidence with ≥1 AMCICO member as an author. Journal metrics, article metrics, and author variables were analyzed using SPSS version 25. RESULTS: Of the 444 surgeons historically belonging to AMCICO, only 126 members contributed a total of 441 articles between 1998 and 2018. An average of 21.00 annual publications with an annual scientific output per capita of 0.05 was found. The most frequent evidence level was III (211 articles, 48%), the highest level was I (12 articles, 3%). The main study objective was clinical research, with 308 articles (70%), and the main study foci was trauma, with 103 articles (23%). An average impact factor of 0.16 and 0.92 was obtained for publications in Spanish and English, respectively. CONCLUSIONS: Scientific publications by AMCICO members are scarce, with a per capita annual index of 0.05 from a total of 441 articles in indexed journals. Second, the impact factor of these journals is low, with a mean value of 0.53. Further strategies should be implemented to increase the number and track the record of Mexican contributions to the scientific literature.

RESUMO

Women underrepresentation in science has frequently been associated with women being less productive than men (i.e. the gender productivity gap), which may be explained by women having lower success rates, producing science of lower impact and/or suffering gender bias. By performing global meta-analyses, we show that there is a gender productivity gap mostly supported by a larger scientific production ascribed to men. However, women and men show similar success rates when the researchers' work is directly evaluated (i.e. publishing articles). Men's success rate is higher only in productivity proxies involving peer recognition (e.g. evaluation committees, academic positions). Men's articles showed a tendency to have higher global impact but only if studies include self-citations. We detected gender bias against women in research fields where women are underrepresented (i.e. those different from Psychology). Historical numerical unbalance, socio-psychological aspects and cultural factors may influence differences in success rate, science impact and gender bias. Thus, the maintenance of a women-unfriendly academic and non-academic environment may perpetuate the gender productivity gap. New policies to build a more egalitarian and heterogeneous scientific community and society are needed to close the gender gap in science.

RESUMO

Exercise stimulates immune responses, but the appropriate "doses" for such achievements are unsettled. Conversely, in metabolic tissues, exercise improves the heat shock (HS) response, a universal cytoprotective response to proteostasis challenges that are centred on the expression of the 70-kDa family of intracellular heat shock proteins (iHSP70), which are anti-inflammatory. Concurrently, exercise triggers the export of HSP70 towards the extracellular milieu (eHSP70), where they work as pro-inflammatory cytokines. As the HS response is severely compromised in chronic degenerative diseases of inflammatory nature, we wondered whether acute exercise bouts of different intensities could alter the HS response of lymphocytes from secondary lymphoid organs and whether this would be related to immunoinflammatory responses. Adult male Wistar rats swam for 20 min at low, moderate, high or strenuous intensities as per an overload in tail base. Controls remained at rest under the same conditions. Afterwards, mesenteric lymph node lymphocytes were assessed for the potency of the HS response (42 °C for 2 h), NF-κB binding activity, mitogen-stimulated proliferation and cytokine production. Exercise stimulated cell proliferation in an "inverted-U" fashion peaking at moderate load, which was paralleled by suppression of NF-κB activation and nuclear location, and followed by enhanced HS response in relation to non-exercised animals. Comparative levels of eHSP70 to iHSP70 (H-index) matched IL-2/IL-10 ratios. We conclude that exercise, in a workload-dependent way, stimulates immunoinflammatory performance of lymphocytes of tissues far from the circulation and this is associated with H-index of stress response, which is useful to assess training status and immunosurveillance balance.

RESUMO

OBJECTIVES: Postgraduate programmes around the world are periodically subjected to research performance evaluation through bibliometric indicators. In this research, we characterized and compared the research performance of 15 universities from Northeastern Brazil, in which 13 were among the top Universities of the Latin America. METHODS: Specifically, total documents, citations and the h-index of each university were retrieved from the Elsevier Scopus database and were analysed not only for historical scientific achievement but also across the period of the past 6 years (2010-2015). Using these bibliometric indicators, we also investigated the performance of programmes at these Universities that have their papers indexed in the Scopus database under the category of "Pharmacology, Toxicology and Pharmaceuticals" for the same period. RESULTS: We found that the Federal University of Pernambuco (UFPE) and the Federal University of Ceará (UFC) were the most productive institutions, producing 17847 and 15048 documents, respectively. The number of papers published by each of these universities in the past six years represented more than 50% of their entire productivity. With regards to their scientific output in "Pharmacology, Toxicology and Pharmaceutics", UFC showed the highest number of published documents followed by UFPE and the Federal University of Paraíba (UFPB). UFC received the highest h-index (with and without self-citations) and number of citations and shared their most cited papers with foreign institutions from the USA and Germany. However, papers from UFC were published in journals with lower impact factors (2.322). CONCLUSIONS: The present study shows where each of these universities stands and can be helpful in identifying potential collaborators in these areas of knowledge.

RESUMO

OBJECTIVE: To study the temporal evolution of the bibliometric indices of internists with established research experience in order to predict the future behavior of researchers and to assess whether output focused on a specific area of internal medicine helps obtain greater visibility than in general internal medicine. MATERIAL AND METHOD: We analyzed a representative group of members of the Spanish Society of Internal Medicine (SEMI) based on data obtained from the Web of Science. As an indicator of productivity, we analyzed the number of articles published. As impact indicators, we studied the impact factor (IF), the number of citations and the h-index. RESULTS: We analyzed 42 internists, with a mean experience of 30 years and a total of 6655 publications. The mean (SD) number of studies was 158 (96), the number of citations was 2,850 (2,865), the IF was 711 (549) and the h-index was 25 (11). These figures were higher for the specialist internists than for the general internists. There was a good relationship between the impact and productivity indicators (R(2)=.61-.89) and a poor relationship between these indicators and the years of experience (R(2)=.13-.19). The temporal evolution of these indicators for each individual researcher and for all researchers as a whole was adjusted to a second-degree polynomial model, with the h-index having the highest R(2) values. CONCLUSIONS: The h-index is the factor that had the best adjustment and least variability and could therefore help predict the future scientific output and impact of internists. The specialist researchers achieved greater visibility than the general internists.

RESUMO

The h-index is an objective and easily calculable measure that can be used to evaluate both the relevance and amount of scientific contributions of an individual author and field. The aim was to examine how the h-index of academic morphologists in Chile relates with academic rank. A descriptive and correlational study was design. We accessed the Chilean Society of Anatomy professor list in January of 2015, for analysis of academic morphologists' h-indexes using the Scopus database, and data was organized by academic rank. Also, m-Quotient was calculated. Institutional productivity was measured, and institutions were ranked on the basis of cumulative h-index, m-Quotient and the total number of publications and citations. For all morphologists analyzed, the mean h-index was 2.9±2.94 (range 0­12). The mean h-indexes were 1.9±2.135 for instructors, 2.5±2.54 for assistant, 5.1±2.89 for associate and 4.7±3.92 for professors. There was a significant relationship between h-index and academic rank (P<0.001). The m-Quotient were significantly different between assistant/associate and professors (P<0.001). By academic degree, the mean h-indexes were 1.0±1.92 for Bachelor, 1.6±2.0 for specialists, 2.3±2.26 for masters and 4.9±3.4 for Ph.D. The total number of publications for Chilean morphologist was 1343 publications (13.85±18.392), with 5321 citations (54.86±106.392). The top 3 institutions were Universidad de La Frontera, Universidad de Chile and Pontificia Universidad Católica de Chile. Multivariate logistic regression analysis demonstrated that h-index (P<0.001) and number of publications (P<0.001) were the best predictors of academic rank. There exists a significant relationship between h-index and academic rank, with h-index increasing with academic rank. It is a reliable tool for quantifying academic productivity within morphology, easily calculable and may be useful when evaluating decisions regarding advancement within academic morphology departments. These results should serve as benchmarks for future studies.

El índice h es una medida objetiva y fácilmente calculable que se puede utilizar para evaluar la importancia y cantidad de contribuciones científicas de un autor y área del conocimiento. El objetivo fue evaluar el índice h de morfólogos académicos en Chile, y su relación con la jerarquía académica. Se diseño un estudio descriptivo correlacional. Se accedido a la lista de profesores de la Sociedad Chilena de Anatomía en enero del 2015; para el análisis del índice h de los académicos morfólogos se utilizó la base de datos Scopus, y los datos fueron organizados por jerarquía académica. Además, se calculó cociente m. Se midió la productividad institucional clasificándose sobre la base de índice h y cociente m acumulados, y el número total de publicaciones y citaciones. Para todos morfólogos analizados, la Media del índice h fue de 2,9±2,94 (rango 0­12). Según jerarquía académica, se observaron índices h de 1,9±2,135 para instructores, 2,5±2,54 para asistentes, 5,1±2,89 para asociados y 4,7±3,92 para profesores titulares. Hubo una relación significativa entre el índice h y jerarquía (P<0,001). Los Cocientes m fueron significativamente diferentes entre los profesores asistente/asociado (mayor) y titulares (P<0,001). Según el grado académico, la Media de los índices h fueron 1,0±1,92 para licenciados, 1,6±2,0 para especialistas, 2,3±2,26 para magíster y 4,9±3,4 para los Ph.D. El número total de publicaciones para los morfólogos chilenos fue 1.343 (13,85±18,392), con 5.321 citas (54,86±106.392). Las 3 mejores instituciones fueron Universidad de La Frontera, Universidad de Chile y Pontificia Universidad Católica de Chile. El análisis de regresión logística multivariante demostró que el índice h (P<0,001) y el número de publicaciones (P<0,001) fueron los mejores predictores de jerarquía académica. Existe una relación significativa entre el índice h y jerarquía, al aumentar el índice h aumenta la jerarquía. El índice h es una herramienta fiable para cuantificar la productividad académica dentro de la morfología, fácilmente calculable y puede ser útil en la evaluación de las decisiones relativas a la promoción dentro de los departamentos académicos en el área morfológica. Estos resultados deben servir como puntos de referencia para futuros estudios.

RESUMO

Objective: To conduct a critical analysis of the two main bibliometric indexes used by science: the impact factor and the H index. Method: Research was conducted on PubMed using the keywords: impact factor, Bibliometrics and H index. Results: The citations of articles tend to follow a curve in which the articles published in a given year increase sharply to a peak occurring between two and six years after its publication. From this peak citations decline over time. Conclusion: The analysis of the scientific merit should not be based on only in bibliometric measure, but in the association of various parameters. The impact factor and the H index is mainly based on the number of citations of scientific papers, and this parameter, although important, should not be used alone, nor overvalued in the evaluation of teaching merit.

Objetivo: Realizar análise crítica dos dois principais índices bibliométricos utilizados pela ciência: o fator de impacto e o índice H. Método: Foi realizada pesquisa no Pubmed utilizando as palavras-chave: impact factor, bibliometrics, H index. Resultados: As citações dos artigos tendem a seguir uma curva em que os artigos publicados em determinado ano aumentam agudamente para um pico que ocorre entre dois e seis anos após sua publicação. A partir deste pico, as citações declinam ao longo do tempo. Conclusão: A análise do mérito científico não deve ser baseada em apenas uma medida bibliométrica, mas em associação de medidas. O FI e o índice H se baseiam fundamentalmente no número de citações dos artigos científicos, e este parâmetro, apesar de importante, não deve ser utilizado sozinho e tampouco supervalorizado na avaliação do mérito docente.

RESUMO

Cuba es un país caracterizado por poseer un gran número de investigadores y profesores, pero no por la cantidad de artículos científicos que publica. El objetivo de este trabajo es caracterizar la producción científica de las ciencias médicas cubanas a partir de la obra de sus autores más productivos y evaluar su experiencia como autor. Se utiliza el asistente de búsqueda GoPubMed y, a partir de la palabra Cuba, se toman los 20 autores cubanos más productivos a los que se les caracteriza su productividad en las bases PubMed y Scopus, además de su índice H. Paralelamente se realiza una encuesta a cada autor por correo electrónico. Entre las variables recogidas más importantes están el tiempo transcurrido desde la graduación hasta la salida del primer artículo, idiomas que prefiere publicar y conocimientos y uso adecuado de herramientas bibliométricas de estos autores. Hay una correspondencia entre el total de los trabajos referidos por cada autor y el total de trabajos recuperados por Scopus. Las correlaciones estadísticamente significativas fueron el número de años transcurridos desde la graduación hasta la fecha de publicación del primer artículo con el total de trabajos referidos por el autor y el total de trabajos recuperados en la base Scopus. Existe correlación significativa entre PubMed y GoPubMed; sin embargo, no resulta significativa entre PubMed y Scopus. A mayor número de trabajos recuperados por Scopus hay un incremento en el número de citas reflejadas en esta base. Los autores más productivos no aprovechan las posibilidades que brinda el conocimiento de los que lo citan y el índice H para trazar estrategias para su desarrollo científico; prefieren escribir en idioma inglés y no tienen uniformidad en la forma en que firman sus trabajos(AU)

Cuba is a country with a large number of researchers and academics but without great quantity of published papers.The aim of this paper is to characterize the scientific production in the Cuban medical sciences throughout the most productive authors and to evaluate their experience in this topic. GoPubMed data base was employed using Cuba as filter Word. The productivity of the twenty most productive Cuban authors in PubMed, GoPubMed and Scopus databases was determined including H index. A questionnaire was sent to each author by email. Among the most important collected variables are the time between their graduation and the appearance of their first paper, favourite publishing language, and knowledges and use of bibiiometric tools. There is a relationship between the total paper published by the author and the number of paper recovered by Scopus. A statistically significant correlation was produced between PubMed and GoPubMed but Scopus. More quantity of recovered papers from Scopus database produced more citations in such database. The most productive authors do not take advantage on the knowledge that the citation offers to make scientific developmental strategies. They prefer to publish in English language and they don't have a unique way to sign their papers(AU)
