Effects of publication bias on conservation planning.

Conservation planners need reliable information on spatial patterns of biodiversity. However, existing data sets are skewed because some ecosystems, taxa, and locations are underrepresented. We determined how many articles have been published in recent decades on the biodiversity of different countries and their constituent provinces. We searched the Web of Science catalogues Science Citation Index (SCI) and Social Science Citation Index (SSCI) for biodiversity-related articles published from 1993 to 2016 that included country and province names. We combined data on research publication frequency with other provincial-scale factors hypothesized to affect the likelihood of research activity (i.e., economic development, human presence, infrastructure, and remoteness). Areas that appeared understudied relative to the biodiversity expected based on site climate likely have been inaccessible to researchers for reasons, notably armed conflict. Geographic publication bias is of most concern in the most remote areas of sub-Saharan Africa and South America. Our provincial-scale model may help compensate for publication biases in conservation planning by revealing the spatial extent of research needs and the low cost of redoing this analysis annually.

Efectos del Sesgo de Publicación sobre la Planeación de la Conservación Resumen Los planeadores de la conservación necesitan información confiable sobre los patrones espaciales de la biodiversidad. Sin embargo, los conjuntos de datos existentes están distorsionados porque algunos ecosistemas, taxones y localidades están subrepresentados. Determinamos cuántos artículos sobre la biodiversidad de diferentes países y sus provincias constituyentes han sido publicados en décadas recientes. Buscamos artículos relacionados con la biodiversidad publicados entre 1993 y 2016 que incluyeran el nombre de países y provincias en los catálogos SCI y SSCI de la Web of Science. Combinamos los datos de frecuencia de publicación de investigaciones con otros factores de escala provincial que creemos afectarían la probabilidad de la actividad de investigación (es decir, desarrollo económico, presencia humana, infraestructura y lejanía). Las áreas que aparentaron estar poco estudiadas en relación con la biodiversidad esperada basada en el clima del sitio probablemente han estado inaccesibles para los investigadores por diferentes razones, notablemente los conflictos armados. El sesgo geográfico en las publicaciones es un tema de importancia para las áreas más remotas del África subsahariana y América del Sur. Nuestro modelo de escala provincial puede ayudar a compensar los sesgos de publicación en la planeación de la conservación al revelar la extensión espacial de las necesidades de investigación y los bajos costos de repetir este análisis cada año.

Análisis bibliométrico de las revistas médicas del Sistema de Clasificación de Revistas Mexicanas de Ciencia y Tecnología.

INTRODUCTION: CONACYT's Mexican Science and Technology Journals Classification System (SCRMCYT) includes the area of medicine and health sciences (M&HS). OBJECTIVE: A bibliometric analysis of M&HS journals listed in SCRMCYT in 2018 was performed. METHOD: Twelve characteristics related to indexation in the Web of Science Core Collection (WoSCC), Scopus, and PubMed databases were analyzed. Indexed journals were analyzed on whether they had recent indexed publications (2017 and 2018). Indexed journals' 50 most-cited articles in WoSCC and Scopus were analyzed. RESULTS: Of the 35 M&HS journals included in the 2018 SCRMCYT list, 31 (89 %) were indexed in Scopus (22 with indexed publications in 2017; 18 in 2018), 17 (49 %) in PubMed (10 with indexed publications in 2017 and 2018), and 12 (34 %) in WoSCC (12 with indexed publications in 2017; 8 in 2018). The 50 most-cited articles had been published only in 4 journals indexed in WoSCC and 5 in Scopus; 60 % were review articles. CONCLUSIONS: Approximately half the 2018 SCRMCYT M&HS journals lack publications indexed in 2018; this suggests that national and international relevance of these journals can be improved.

INTRODUCCIÓN: El Sistema de Clasificación de Revistas Mexicanas de Ciencia y Tecnología (SCRMCYT) del Conacyt incluye el área de medicina y ciencias de la salud (MyCS). OBJETIVO: Se realizó un análisis bibliométrico de las revistas del MyCS del listado SCRMCYT-2018. MÉTODO: Se analizaron 12 características relacionadas con la indización en las bases de datos Web of Science Core Collection (WoSCC), Scopus y PubMed. Se analizó si la revista indizada tenía publicaciones indizadas recientes (años 2017 y 2018). Se analizaron los 50 artículos más citados de las revistas indizadas en Scopus y WoSCC. RESULTADOS: De 35 revistas de MyCS incluidas en el SCRMCYT-2018, 31 (89 %) estaban indizadas en Scopus (22 con indización vigente en 2017 y 18 en 2018), 17 (49 %) en PubMed (10 vigentes en 2017 y 2018) y 12 (34 %) en WoSCC (12 vigentes en 2017 y ocho en 2018). Los 50 artículos más citados provenían de solo cuatro revistas indizadas en WoSCC y de cinco en Scopus; 60 % eran artículos de revisión. CONCLUSIONES: Aproximadamente la mitad de las revistas de MyCS del SCRMCYT-2018 carecen de indización vigente en 2018, por lo que la relevancia nacional e internacional de estas revistas puede mejorar.

Medición de la obsolescencia de la información en revistas de salud pública de México.

INTRODUCCIÓN: En el proceso de comunicación científica, la obsolescencia se define como el descenso de la validez o utilidad de la información en el tiempo. OBJETIVO: Determinar el grado de obsolescencia de la información publicada en tres revistas de salud pública en México y cuantificar su pérdida de utilidad anual en un lapso determinado. MÉTODO: Estudio bibliométrico multisincrónico de revistas indizadas, arbitradas y activas, con más de 30 años de antigüedad. Variables analizadas: año de publicación de los artículos fuente, año de las referencias, edad de estas últimas. De las referencias de los artículos originales publicados entre 2008 y 2013 se obtuvieron variables e indicadores conforme el modelo matemático de Brooks y el método de la vida media. RESULTADOS: Se obtuvieron medidas de obsolescencia y valores medios de las variables para cada revista. Los valores indicaron vida media de 7.5 años; promedio de actualidad de 39.76 %, factor de envejecimiento de 91.15 %, pérdida de utilidad de 8.85 % anual, lo que representa la obsolescencia de la literatura en este tema y el país. CONCLUSIÓN: Este estudio delinea un perfil de obsolescencia para cada revista: el factor de envejecimiento y la pérdida anual de utilidad son consistentes con los mostrados por las principales revistas de salud pública en América Latina y España. INTRODUCTION: In the process of scientific communication, obsolescence is defined as the decrease of information validity or usefulness over time. OBJECTIVE: To determine the degree of obsolescence of information published in three public health journals in Mexico and quantify their annual utility loss in a given period. METHOD: Multisynchronous bibliometric study of indexed, peer-reviewed and active journals, with more than 30 years of existence. Analyzed variables: source articles' year of publication, references' year, age of the latter. From the references of original articles published between 2008 and 2013, variables and indicators were obtained according to Brooks' mathematical model and the half-life method. RESULTS: Obsolescence measurements and variables' mean values were obtained for each journal. The values obtained indicate a half-life of 7.5 years; actuality average, 39.76%; aging factor, 91.15%; loss of usefulness, 8.85% per year, which represents obsolescence of literature on this subject and country. CONCLUSIONS: This study delineates an obsolescence profile for each journal: the aging factor and annual loss of usefulness are consistent with those shown by the leading public health journals in Latin America and Spain.

Preprints in biomedicine: alternative or complement to the traditional model of publication? / Preimpresiones en biomedicina: ¿alternativa o complemento al modelo tradicional de publicación?

The peer-review system has allowed the quality control of the manuscripts submitted for publication to scientific journals for over three centuries. However, due to its relative slowness and other drawbacks, some researchers, mainly in the areas of Physics and Mathematics, started some decades ago to propagate, by electronic means, manuscripts not yet submitted to a journal for formal publication. The dissemination of this practice led to the establishment of permanent repositories like ArXiv, to which preprints can be sent to be published whitou charge, allowing also the search and download of the works they contain with no payment required from the reader. In biomedical sciences, the adoption of the system has been slower than in the exact sciences and previous attempts like e-biomed, Netprints, and Nature Precedings did not prosper. A new generation of repositories like bioRXiv, inspired by ArXiv, seems to enjoy an increasing acceptance among biomedical researchers. Here, we discuss the potential role of this emerging system to establish discovery priority in biomedicine and to improve manuscripts before they are submitted to scientific journals besides other applications which could be implemented in the extent that the model becomes more popular.

La revisión por pares es un sistema que ha permitido el control de calidad de los manuscritos enviados para publicación en revistas científicas durante más de tres siglos. Sin embargo, debido a su relativa lentitud y otras desventajas, algunos investigadores (principalmente en las áreas de la física y las matemáticas) iniciaron hace algunas décadas la difusión electrónica de manuscritos aún no sometidos a una revista de publicación formal. La popularización de esta práctica condujo al establecimiento de repositorios permanentes como ArXiv, a los que es posible enviar preimpresiones de forma gratuita y que a la vez permiten la búsqueda y descarga de los trabajos que contienen sin cargo para el lector. En las ciencias biomédicas la adopción de este sistema ha sido más lenta que en las ciencias exactas e intentos previos como e-biomed, Netprints y Nature Precedings no prosperaron. Una nueva generación de repositorios como bioRXiv, inspirado en ArXiv, parece gozar de una creciente aceptación entre investigadores biomédicos. Aquí discutimos el potencial papel de este sistema emergente para establecer la primicia de descubrimientos en biomedicina y el mejoramiento de manuscritos antes de su sometimiento a revistas científicas, así como para otras aplicaciones que podrían implementarse en la medida en que el modelo se popularice.

Social networks in radiology: Toward a new paradigm in medical education?

The universally accepted system for the transmission of scientific knowledge in the field of medicine has long been grounded in scientific publications. Social networks can be a useful alternative or complementary method of transmitting this knowledge. Social networks (e.g., Twitter, Instagram, Facebook, LinkedIn, YouTube, and TikTok) generate educational contents that enable quality training, despite their informality. Each of these networks has strengths and weaknesses that users should know about. These platforms are free and allow for real-time discussion. They make it easy to incorporate content and to contact experts or access sources of knowledge directly. Aware of their influence, publishers have incorporated metrics to measure the impact of their articles in social networks (Altmetrics). These networks should be incorporated into departmental training programs immediately. Nevertheless, navigating through social networks is complex, and the hashtag-based system of searching is inefficient, limiting their use in education. Despite the informality of the knowledge generated on social networks, the importance of these networks as a source of knowledge is growing. Radiology departments must design a strategy for using social networks for education rather than for propaganda, creating well-organized focal groups that search for contents through systematic, filtered review of information, digital repositories, and review sessions and for sharing this knowledge both inside and outside the department. Departments must also implement a strategy for communicating through these networks.

Association of trial characteristics with simultaneous publication and its impact on citations and mentions: a cross-sectional study.

INTRODUCTION AND OBJECTIVES: Randomized trials are often presented at medical conferences and published simultaneously or later. Predictors of simultaneous publication and its consequences are undetermined. Our aim was to characterize the practice of simultaneous publication, identify its predictors, and evaluate its impact. METHODS: In this cross-sectional study, we included randomized trials presented at late-breaking science sessions of major cardiovascular conferences from 2015 to 2021. The association of trial characteristics with the timing of publication was analyzed. The impact of simultaneous vs nonsimultaneous publication was investigated on the number of 1-year citations and 1-month mentions, and the total citations and mentions at the longest observation follow-up. RESULTS: Of 478 trials included in the analysis, 48.7% were published simultaneously. Simultaneous publications were more likely to be presented in the main conference room (OR, 6.09; 95%CI, 1.34-36.92; P=.029) and were characterized by a shorter review time (OR, 0.95; 95%CI, 0.91-0.96; P<.001). Simultaneous publications were associated with higher 1-year citations (R2, 43.81; 95%CI, 23.89-63.73; P<.001), 1-month mentions (R2, 132.32; 95%CI, 85.42-179.22; P<.001) and total citations (R2, 222.89; 95%CI, 127.98-317.80; P<.001). CONCLUSIONS: Randomized trials presented in the main conference room and with shorter review time were more likely to be published simultaneously. Simultaneous publications were associated with more citations and mentions than nonsimultaneous publications.

[Medical practice and clinical research: keys to generate knowledge and improve care]. / Práctica médica e investigación clínica: claves para generar conocimiento y mejorar la atención.

The increased quality in medical care may be immediately accomplished if clinical research is integrated into daily clinical practice. In the generation of medical knowledge are four steps: an unanswered question awakened from clinical practice, the critical analysis of specialized literature, the development of a research protocol, and, finally, the publication of outcomes. Decision making and continuous training are becoming part of an effective strategy of medical attention improvement.

El conocimiento médico que integra la investigación clínica a la práctica médica cotidiana incrementa la calidad de la atención de manera inmediata. En el proceso de la generación de conocimiento médico se distinguen cuatro pasos: hacer un cuestionamiento sobre la práctica médica, analizar el conocimiento publicado en la literatura especializada, desarrollar un protocolo de investigación y publicar los resultados. Es indispensable propiciar decisiones fundadas en la investigación clínica para favorecer el desarrollo de estrategias que mejoren la calidad de la atención.

Bibliometric analysis of original articles of journal Enfermería Intensiva in the period 2001-2020.

INTRODUCTION: Bibliometric analysis allow the quantitative evaluation of the characteristics of a scientific publication. OBJECTIVE: To perform a bibliometric analysis of original articles in the journal Enfermería Intensiva from 2001 to 2020. RESULTS: The journal Enfermería Intensiva has published, between 2001 and 2020, 438 works, of which 259 are original articles (59.1%). These original articles are mostly quantitative studies (76.1%), with an average of 30.5 bibliographic references (SD 13.9), 4.9 citations (SD 1.7) in the Web of Science and Scopus repertoires, and 15,489.5 visits/downloads (median 9090 and interquartile range 4567-15,260) according to information on the magazine's website. These originals have been signed by 1345 authors, which represents a collaboration index of 5.2. 78.0% of the authors are sporadic, having published only one work. Most of the articles come from authors who work in institutionally located in hospitals and university centers, and geographically in the Communities of Madrid, Cataluña, Navarra and Andalucía. CONCLUSIONS: There is little international, regional and institutional collaboration, producing the highest level of collaboration between authors from the same center. The journal has established itself in the panorama of scientific nursing research in Spain and shows bibliometric indicators similar or even superior to other publications in its environment.

Scientific production in heart failure in Peru: a bibliometric study.

OBJECTIVE: To analyze the Peruvian scientific production on Heart Failure (HF) in the period 2000-2020. METHODS: We performed an observational bibliometric study, in the Scopus and Scielo database, of documents published on heart failure by an author with Peruvian affiliation, between the years 2000 and 2020. We describe variables of scientific production, number of annual publications, documents, characteristics of the publications, and institutions. The collaborative networks were analyzed by building a network of nodes using the VOSViewer v1.6.5 software. RESULTS: A 236 publications were found in Scopus and 55 in Scielo. The largest number of documents were original articles followed by review articles. The journal "The Lancet" and "Revista Peruana de Medicina Experimental y Salud Pública" were those that had the highest number of publications. Thirty-one countries were registered that had at least 5 documents published with an author from Peru. Scientific collaboration was mainly with the United States and at the regional level with Argentina. 55 documents were published with only Peruvian authors. CONCLUSION: The scientific production in HF by Peruvian authors is in exponential growth. And the Universidad Peruana Cayetano Heredia/CRÓNICAS is the Peruvian institution with the most publications on it.

Women occupying preferential authorship positions for articles in the journal Emergencias: an analysis of authorship during the last decade. / Mujeres ocupando autorías preferenciales de artículos en la revista EMERGENCIAS: análisis de la última década.

OBJECTIVES: To analyze gender disparity in scientific productivity reflected by the authorship of articles in the journal Emergencias over the past decade. MATERIAL AND METHODS: Retrospective longitudinal study. We included articles in all issues published between January 2011 and December 2020, analyzing the number of authors, their gender, article type, year of publication, and preferential authorship credit (first author, corresponding author, and last author positioning). The percentages of women named in each position were calculated, and the trend over time was analyzed. RESULTS: A total of 1240 articles signed by 5213 authors were collected; a woman was named in 1889 of the cases (36.2%). A woman was the first author of 384 articles (31%), the corresponding author of 352 (28.4%), and the last author of 358 (28.9%). The number of female authors of original research articles or meta-analyses tended to increase over time (P = .047), but no statistically significant gender trends were observed in the authorship of editorials, narrative reviews, scientific letters or short communications, letters to the editor, or any other publication category. CONCLUSION: The publication of articles by women in Emergencias has increased over the past decade. However, women continue to author fewer articles than men.

OBJETIVO: Analizar la desigualdad de género en la producción científica de la revista EMERGENCIAS en la última década. METODO: Estudio longitudinal retrospectivo que revisó los números publicados entre enero de 2011 y diciembre de 2020. Se analizaron el número de autores, género, tipo y año de publicación y autoría preferencial (primera autoría, autoría de correspondencia o última autoría). La participación de la mujer se calculó en base a valores porcentuales y se analizó la tendencia existente a lo largo de los años. RESULTADOS: Se recogieron 1.240 artículos con un número total de 5.213 firmantes, 1.889 de ellos (36,2%) mujeres. En 384 (31%) artículos, una mujer asumió la primera autoría, en 352 (28,4%) fue autora para correspondencia y en 358 (28,9%) la última autora. A lo largo de la década, se identificó una tendencia creciente en los que una mujer fue primera autora en los artículos originales o metanálisis (p = 0,047). En los editoriales, revisiones, cartas científicas o comunicaciones breves, cartas al editor y otros no existió una tendencia creciente significativa en las autorías preferenciales. CONCLUSIONES: La participación de autoras en la producción científica de la revista EMERGENCIAS ha aumentado en la última década. No obstante, comparado con la de hombres, sigue existiendo una menor participación.

Fourteen Crutches for Mediocrity. The logismoi that jeopardize good research and publication.

Publications are used widely as a measure of academic quality. Many investigators have difficulty publishing in this competitive field. After coming across a religious lecture on the "Fourteen Crutches for Mediocrity", our team adapted this approach to life to the science of publishing: (1) what is the problem of doing it?; (2) there are worse!; (3) everybody does it!; (4) why exaggerate?; (5) I will do it tomorrow!; (6) maybe if …; (7) it is not used anymore!; (8) be a cousin not a brother!; (9) I need to be thanked!; (10) don't eat your own head, let it be!; (11) I can't possibly accomplish it!; (12) I don't feel like doing it!; (13) I am fed up!; (14) I am not worthwhile! These crutches jeopardize good research and thoughtful learned publications.

[Evaluation of competences in scientific writing after two different types of training courses: SCRIU-B study protocol]. / Evaluación de competencias en redacción científica tras dos modalidades diferentes de cursos de formación: protocolo del Estudio SCRIU-B.

Scientific writing is one of the competences required and requested by health professionals. There are several course formats designed for acquiring these competences, although the improvement after taking part in these courses is not always demonstrated. Through an open and non-randomized experimental design, the SCRIU-B study aims to evaluate the acquisition of competencies in scientific writing after specific training courses (face-to-face and online) as well as the satisfaction of the participants with these courses. A control group with participants from other training workshops not related to scientific writing is included. Through different questionnaires about knowledge, attitudes and skills we will evaluate and compare the improvement of their scientific writing skills. The results of the study will allow us to assess the usefulness of these courses and improve their format and implementation.

Gender Differences in Original Archivos de Bronconeumología Publications, 2001-2018. / Diferencias de género en las publicaciones originales de Archivos de Bronconeumología en el periodo 2001-2018.

INTRODUCTION: Gender inequality exists in scientific publications. The aim of this study was to determine changing patterns in gender differences and factors associated with the positioning of authors' names in original articles published in Archivos de Bronconeumología (AB). METHODS: We performed a bibliometric study of articles published in AB between 2001 and 2018. Author gender was analysed in four scenarios: first author, last author, middle authors, and mentee authors. Comparisons were made by authors' specialties, funding received, multicentre studies, specialist areas, and others. Multivariate models adjusted for the percentage of registered physicians in the Spanish health system were created to predict the female gender of the first, middle, and last author. RESULTS: A total of 828 publications were analysed in which women appeared as first authors in 286 (34.5%) and last authors in 169 (20.4%). A gradual increase in women as first authors was observed (P = .0001), but not as last authors (P = .570). Overall, the average number of female authors increased over time (from 1.6 ± 1.4 in 2001-2005 to 3.3 ± 2.3 in 2016-2018, P = .0001), with no differences in male averages. The adjusted multivariate models reflected a positive bi-directional relationship between the first author and the middle authors, and a negative association between the first author being Spanish and the last author being female (OR 0.57; 95% CI 0.36-0.88, P = .012). CONCLUSIONS: Gender differences were found in various aspects of authorship in AB, summarized by a greater participation of women as first and intermediate authors, but not as last authors.

Trend in Spanish cardiology research and global comparative analysis of major topics.

INTRODUCTION AND OBJECTIVES: We used bibliometric techniques to analyze the participation of Spanish institutions in research on major cardiovascular topics during the last 4 decades. METHODS: Bibliometric indicators of production, collaboration and impact were obtained from the Science Citation Index Expanded (SCIE) database. Search strategies were used in major topics and institutional collaboration networks were identified, represented using the Kamada-Kawai algorithm. RESULTS: Global cardiovascular publications doubled from 2000 to 2018. In 2018, those by Spanish authors represented 2.33%, with a participation of between 7% and 1.84%, depending on the topics analyzed. The offset with respect to global production was between 0 and 7 years. Annual growth rates were higher in more recent topics. Revista Española de Cardiología published the largest number of articles from Spanish institutions. The journals generating the highest number of citations in the chosen topics were the Journal of the American College of Cardiology, Europace, and the European Heart Journal. Analysis of collaboration revealed a close interrelation between Spanish and foreign institutions, as well as groups with high production publishing independently. CONCLUSIONS: The analysis disaggregated by subject showed the sustained growth of Spanish cardiovascular scientific production and more rapid growth in recently appearing topics. Collaboration networks showed a high degree of interrelation between Spanish and foreign institutions, including hospitals, universities, research institutes, and scientific societies.

[Gender inequalities in authorship of the main Spanish medical journals in 2017]. / Desigualdades de género en la autoría de las principales revistas médicas españolas durante el año 2017.

INTRODUCTION: Some studies have shown a lower female participation in scientific publications. The objective of this study is to analyse the gender inequalities in the main Spanish journals of medical publications. MATERIAL AND METHOD: Cross-sectional study of the main Spanish medical journals classified by SCImago Journal & Country Ranking (n=24) and their publications (n=3.375), during the year 2017. Women/men ratio in authorship was calculated for all journals and types of papers. Bivariate analyses were developed with the type of article as the dependent variable, and gender, institution, and country of the first and last authors as the independent variables. Logistic regression models were performed to calculate adjusted odds ratios (aOR) and their 95% confidence intervals (95% CI) of the types of papers according to authorship gender, institution, and country. The statistical program used was R. RESULTS: The total number of authors was 16,252 (44.2% women, 53.9% men, and 1.9% non-identified gender). Women represented 46% of the first authors and 33.5% of the last ones. Women were the first authors of Editorials less often than men (aOR 0.39; 95% CI 0.30-0.51), but more often in Originals (aOR 1.55; 95% CI 1.33-1.80). Women were the last authors with less frequency in all types of papers, especially in Editorials (aOR 0.50; 95% CI 0.35-0.70). The women/men ratio in authorship was less than 0.80 in 10 of 26 journals analysed (41.7%). CONCLUSIONS: These results show the gender inequalities in the authorship of the main Spanish medical journals in 2017, especially as first authors and Editorials.

Factores relacionados con la publicación de los trabajos de investigación presentados en los congresos científicos nacionales de estudiantes de Medicina de Perú entre los años 2017-2019 / Factors related to the publication of research papers presented at medical student national scientific conferences in Peru between 2017 and 2019

RESUMEN Objetivo: Describir las características de los trabajos presentados en los congresos de estudiantes de Medicina de la Sociedad Médico Estudiantil Peruana entre los años 2017 y 2019, así como los factores relacionados para su publicación. Materiales y métodos: Estudio de diseño observacional, transversal, bibliométrico y retrospectivo, de fuente secundaria en base a los libros de resúmenes de los trabajos de los congresos científicos entre los años 2017 y 2019. Los datos se analizaron mediante el software Stata, versión 13, y con estadística descriptiva. En el análisis multivariado se calcularon razones de prevalencias, con un intervalo de confianza al 95 % y p < 0,05 en los análisis crudos y ajustados. Resultados: De los 447 trabajos presentados, 170 (38,0 %) fueron investigaciones concluidas; 168 (37,6 %), protocolos de investigación, y 109 (24,4 %), casos clínicos. El 52,1 % (n = 233) de los autores procedían de una universidad de Lima; el 40,9 % (n = 183) eran de universidades públicas. En 376 de los trabajos (52,1 %), hubo un asesor entre los autores, de los cuales 332 (88,3 %) fueron médicos. La frecuencia de publicaciones fue 11,4 %. La prevalencia de publicación en formato de artículo original fue 131 % mayor (RPa: 2,31; IC 95 %: 1,22-4,37, p = 0,010) y 63 % menor (RPa: 0,37; IC 95 %: 0,17-0,81, p = 0,014) en los trabajos que fueron presentados en el año 2019 en comparación con el año 2017, lo cual fue estadísticamente significativo, con p < 0,05. Conclusiones: Uno de cada diez resúmenes de trabajos presentados en los congresos de la Sociedad Científico Médico Estudiantil Peruana (Socimep) fueron publicados, un número que sigue siendo bajo. Entre los factores asociados a la publicación se consideraron la presentación de un trabajo en formato de artículo original y del año 2019. Los resultados del presente estudio contribuirán a que las autoridades universitarias fortalezcan la investigación mediante estrategias y/o programas vinculados con la producción de índole científico estudiantil.

ABSTRACT Objective: To describe the characteristics of papers presented at medical student conferences of Sociedad Científica Médico Estudiantil Peruana (SOCIMEP Peruvian Medical Student Scientific Society) between 2017 and 2019, as well as the factors related to their publication. Materials and methods: An observational, cross-sectional, bibliometric, retrospective and secondary-source study based on the books of abstracts of papers presented at scientific conferences between 2017 and 2019. The data were analyzed with the Stata Statistical Software: Release 13 using descriptive statistics. In the multivariate analysis, prevalence ratios were calculated with a 95 % confidence interval and p < 0.05 in the crude and adjusted analyses. Results: From a total of 447 papers, 170 (38.0 %) were completed research studies, 168 (37.6 %) research protocols and 109 (24.4 %) case reports. In addition, 233 (52.1 %) authors came from a university in Lima and 183 (40.9 %) were from public universities. Moreover, 376 (52.1 %) papers had an advisor among the authors, 332 (88.3 %) of whom were physicians. The frequency of publications accounted for 11.4 %. The prevalence of original-article publications was 131 % higher (aPR: 2.31; 95 % CI: 1.22-4.37, p = 0.010) and 63 % lower (aPR: 0.37; 95 % CI: 0.17-0.81, p = 0.014) among papers presented in 2019 compared to 2017, thus being statistically significant, with p < 0.05. Conclusions: One out of 10 abstracts of papers presented at SOCIMEP conferences was published; however, this number is still low. Among the factors associated with the publication were presenting a research paper as an original article and in 2019. The results of this study will help the university leadership to strengthen research through strategies and/or programs linked to the student scientific production.

Métricas de los artículos publicados en la revista científica Finlay, 2011-2022 / Metrics of the articles published in the Finlay journal, 2011-2022

RESUMEN Objetivo: Caracterizar los artículos publicados en la revista científica Finlay durante el periodo 2011-2022. Materiales y métodos: Se realizó un estudio observacional, descriptivo, bibliométrico sobre los artículos publicados en la revista científica Finlay. El universo estuvo conformado por 525 artículos. No se aplicó técnicas de muestreo. Las variables analizadas fueron cantidad de artículos, año de publicación, cantidad y procedencia de los autores, tipo, temática central de los artículos, tipo de estudios, cantidad de referencias y referencias con cinco años de antigüedad, cantidad de citas por artículos y recibidas por la revista por años. Se aplicó la estadística descriptiva e indicadores bibliométricos. Resultados: Destacó el año 2021, con 60 investigaciones (11,38 %). Predominaron los artículos con tres autores (155; 29,52 %); sobresalió Cienfuegos, con 1074 autores (59,40 %), y prevalecieron los artículos originales (AO) (243; 46,28 %). El mayor índice de Price (IP) (0,80) lo presentaron las imágenes en la medicina (IM). Dentro de los AO, sobresalieron las investigaciones con metodología de enfoque observacional-descriptivo (225 artículos publicados, equivalente a un 92,59 % respecto al total de AO). Destacaron investigaciones relacionadas con enfermedades cardiovasculares (116; 22,09 %). Se recibieron 4870 citas, con predominio del año 2017, con un número de citas corregidas (NCC) de 38,3; mientras que, en el año 2020, hubo 3,27 de factor de impacto (FI). Conclusiones: La revista Finlay constituye un órgano científico para la difusión de resultados investigativos con amplios logros y experiencias en la gestión editorial. Su crecimiento ha sido exponencial en cuanto a la cantidad de artículos publicados, con predominio en el año 2021. En sus números se recogen investigaciones que muestran la colaboración entre autores tanto nacionales como extranjeros, y en donde se resalta los resultados de los investigadores del territorio. Al respecto, las temáticas son referentes a problemas de salud que se recogen en los programas de salud prioritarios para el sector, fundamentados en investigaciones originales en mayor medida, y aparejado a un crecimiento de las citas recibidas en especial en el 2017.

ABSTRACT Objective: To characterize the articles published in the Finlay journal during the period between 2011 and 2022. Materials and methods: An observational, descriptive, bibliometric study was carried out on the articles published in the Finlay journal. The universe consisted of 525 articles. Sampling techniques were not used. The analyzed variables were number of articles, year of publication, number of authors, origin of the authors, type of article, main theme of the articles, type of study, number of references, number of 5-year-old references, number of citations per article and number of citations received by the journal per year. A descriptive statistics and bibliometrics were used. Results: The year 2021 stood out with 60 research works (11.38 %). Articles with three authors prevailed (155; 29.52 %), Cienfuegos stood out with 1,074 authors (59.40 %) and original articles (OA) predominated (243; 46.28 %). Images in medicine (IM) had the highest Price's Index (0.80). Among the OA, research works with an observational-descriptive approach prevailed (225 published articles, which accounted for 92.59 % out of the total number of OA). Research related to cardiovascular diseases predominated (116; 22.09 %). A total of 4,870 citations were received, most of them from 2017, with a number of corrected citations (NCC) of 38.3. Meanwhile, the year 2020 had an impact factor (IF) of 3.27. Conclusions: The Finlay journal is a scientific body for the dissemination of research results with extensive achievements and experiences in editorial management. Its growth has been exponential in terms of the number of articles published, prevailing the year 2021. Its issues include research works that show the collaboration between national and foreign authors, highlighting the results of the Cienfuegos province's researchers. In this regard, the topics focus on health problems that are included in the sector's priority health programs, based on original research to a greater extent and coupled with a higher number of citations received especially in 2017.

[Profile of the Family Doctor who gains access to positions with teaching tutorship of Family and Community Medicine by means of relocation examination in Galicia]. / Perfil del médico de familia que accede a plazas con tutoría docente de Medicina Familiar y Comunitaria mediante concurso de traslados en Galicia.

OBJECTIVE: To analyse the profile of Family Doctors who gain access to positions, both to the general quota, as well those reserved for teaching tutors of Family and Community Medicine, by means of a relocation competition. MATERIAL AND METHODS: A descriptive observational study was conducted in which 2 comparison groups were established: A Non-Teaching group that did not include Family Doctors who did not request or gain access to tutor positions, and a Teaching group with those that gained access to positions reserved for tutors. The information was obtained from the marks of the relocation competition carried out in Galicia in 2018. A total of 426 General Practitioners that entered the examination were included, of which 301 were female (70.7%) and 125 (29.3%) males. The variables were the obtaining of a position reserved for tutor, gender, and the merits considered in the competition: professional experience, training, scientific publications, and Galician language. The non-parametric statistics tests of Mann-Whitney and Kruskal-Wallis were used, after checking for non-normal distribution. RESULTS: Statistically significant differences were found in the distribution by gender in favour of males in the Teaching group compared to the Non-Teaching group (P<.01). The Teaching group obtained better results in training and publications. The females obtained statistically significant results in their favour in the training variable, and the males in experience. CONCLUSIONS: For the choice of teaching places in relocation interviews and examinations, publications and training had an important weighting; but, taking the gender perspective into account, a lower percentage of women had gained access to teaching positions due to having lower score in the experience category.
