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

INTRODUCCIÓN: La desigualdad de género existe en las publicaciones científicas. El objetivo del estudio fue determinar la evolución histórica de las diferencias de género y factores asociados a las posiciones de las autorías de los trabajos originales de Archivos de Bronconeumología (AB). MÉTODOS: Estudio bibliométrico de AB en el periodo 2001-2018. Se analizó el género de las autorías en cuatro escenarios: primera firma, última firma, autorías intermedias y mentorizadas. Se realizaron comparaciones por especialidad firmante, financiación recibida, carácter multicéntirico y área temática, entre otras. Se crearon modelos multivariantes ajustados por el porcentaje de médicas colegiadas en el sistema sanitario español para predecir el género femenino de la primera, intermedia y última firma. RESULTADOS: Se analizaron 828 publicaciones, donde las mujeres figuraron como primeras autoras en 286 (34,5%) y como últimas en 169 (20,4%). Se observó un incremento gradual de mujeres como primeras autoras (p = 0,0001), pero no como últimas firmantes (p = 0,570). En general, la media de autoras mujeres aumentó con el tiempo (1,6 ± 1,4 en 2001-2005 a 3,3 ± 2,3 en 2016-2018, p = 0,0001), sin apreciarse diferencias en las medias de hombres. Los modelos multivariantes ajustados reflejaron una relación bidireccional positiva entre la primera autoría y las intermedias, y una asociación negativa entre que el primer autor haya sido español con una última autoría femenina (OR 0,57; IC95% 0,36-0,88, p = 0,012). CONCLUSIONES: Se encontraron diferencias de género en varios aspectos de las autorías de AB, resumidas en una mayor participación de las mujeres como primeras firmantes e intermedias, pero no como últimas autoras

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

Análisis de las métricas alternativas de Archivos de Bronconeumología durante el periodo 2014-2018 / Altmetrics Analysis of Archivos de Bronconeumología From 2014 to 2018

INTRODUCCIÓN: Las métricas alternativas o altmetrics son todas aquellas mediciones de la producción científica diferentes a los indicadores clásicos y recogen su influencia mediática en redes sociales y canales de difusión similares. El objetivo del estudio fue analizar el impacto mediático de Archivos de Bronconeumología en 2 agregadores de altmetrics y de las visitas a su página web. MÉTODOS: Estudio observacional de los artículos originales, de revisión y de consenso de Archivos de Bronconeumología durante el periodo 2014-2018. Se analizaron los agregadores PlumX Metrics y Altmetric, y las visitas a la página web de Archivos de Bronconeumología. Se realizaron 5 comparaciones: por especialidad firmante, por financiación recibida, por número de centros participantes, por tipología documental y por área temática. Como subanálisis, se correlacionaron las altmetrics con las citaciones convencionales. RESULTADOS: Se analizaron 273 publicaciones de las que 186 fueron artículos originales (68,1%). Las publicaciones de Neumología y las de revisión y consenso obtuvieron mayor impacto mediático en los 2 agregadores analizados, así como en las visitas a la página web. El score medio de atención de Altmetric fue de 1,9±4,4 (rango 0-59), por encima del promedio para la antigüedad de la publicación. Se documentó una correlación estadísticamente significativa débil a moderada entre las altmetrics y las citaciones clásicas. CONCLUSIONES: Las publicaciones de revisión, de consenso y las de Neumología tuvieron mayor impacto mediático. El score medio de atención de Altmetric fue superior al promedio en función de la antigüedad de las publicaciones. Se objetivó una correlación débil a moderada de las altmetrics con las citaciones convencionales

INTRODUCTION: Alternative metrics or altmetrics are non-traditional measurements of scientific production that reflect a publication's influence in social networks and similar channels of dissemination. The aim of this study was to analyze the media impact of Archivos de Bronconeumología according to 2 altmetric aggregators and website visits. METHODS: This was an observational study of the original articles and review and consensus articles published in Archivos de Bronconeumología during the period 2014-2018. Data from the PlumX Metrics and Altmetric aggregators and visits to the Archivos de Bronconeumología website were analyzed. Five comparisons were made: by specialty area, by funding received, by number of participating centers, by document type, and by topic. In a subanalysis, altmetrics were correlated with the conventional citation system. RESULTS: We analyzed 273 papers, of which 186 were original articles (68.1%). The papers that achieved greater media impact in the 2 aggregators analyzed, and in terms of website visits, were pulmonology papers and review and consensus articles. The mean Altmetric Attention Score was 1.9±4.4 (range 0-59), which is above average for the date of publication of the paper. A statistically significant weak to moderate correlation was identified between altmetrics and conventional citations. CONCLUSIONS: Review articles, consensus documents, and pulmonology papers had a greater media impact. Mean Altmetric Attention Score was higher than the average based on the date of publication. A weak to moderate correlation between altmetrics and conventional citations was identified

Aplicaciones de las nuevas tecnologías en la deshabituación tabáquica: telemedicina y gamificación / Applications of the new smoking cessation technologies: telemedicine and gamification

La telemedicina y la gamificación son dos estrategias basadas en las tecnologías de la información y comuni-cación que se pueden utilizar en una amplia variedad de patologías, entre las que se incluye el tabaquis-mo. Los programas basados en la telemedicina han demostrado ser similares a la asistencia convencional consiguiendo la deshabituación tabáquica a corto y largo plazo, si bien los estudios han ratificado que la telemedicina no es válida para todos los pacientes y de-bemos investigar más sobre los factores que se asocian a una mejor adherencia del paciente al programa. Por otro lado, en el momento actual solo se ha publicado un estudio sobre la gamificación en la deshabituación tabáquica, aunque sus aplicaciones potenciales podrían favorecer la adquisición de hábitos de vida saludable y aumentar la predisposición de los fumadores para realizar un intento de deshabituación

Telemedicine and gamification are two strategies based on the use of information and communication techno-logies. Both of them could be used in a large variety of pathologies, including smoking cessation. Teleme-dicine programs have shown similar results compared with usual care in terms of smoking cessation at the short and large time. While the studies have ratified that telemedicine is not valid with all patients and should be investigated about factors related to bet-ter patients' adherence to the program. On the other hand, actually, only one article about gamification has been published although their possibilities for impro-ving healthy lifestyle or the patient predisposition to make an attempt to smoking cessation should be in consideration in future studies

Trombosis en el muñón arterial de cirugías de resección pulmonar: análisis de su presentación clínica, tratamiento y evolución / Arterial Stump Thrombosis after Lung Resection Surgery: Clinical Presentation, Treatment and Progress

Objetivo: Determinar la prevalencia de trombosis de muñón arterial (TMA) en cirugías de resección pulmonar por carcinoma broncogénico, y describir su evolución radiológica y tratamiento. Material y métodos: Estudio observacional y retrospectivo de casos de TMA detectados mediante angiotomografías con contraste intravenoso (TAC). La comparación de variables clínicas, radiológicas, y el análisis de supervivencia mediante curvas de Kaplan-Meier, se realizó planteando 3 grupos: pacientes con TMA, pacientes con tromboembolismo pulmonar (TEP) y pacientes sin TMA ni TEP. Resultados: Se detectaron 9 TMA en 473 cirugías (1,9%), 6 de ellas en el lado derecho (67% de las TMA), con una mediana de tiempo de detección desde la cirugía de 11,3 meses (rango intercuartílico 2,7-42,2 meses). Salvo el número de TAC en pacientes con TMA comparados con el grupo sin TEP ni TMA, y la recidiva tumoral en pacientes con TEP en comparación con los restantes 2 grupos, no se encontraron diferencias estadísticamente significativas en las características basales ni en las oncológicas. Igualmente no se encontraron diferencias en el análisis de supervivencia. Conclusiones: En nuestra serie, la TMA fue una patología infrecuente que tendió a localizarse en las cirugías del lado derecho, y cuya detección a lo largo del tiempo fue variable. No se asoció a factores de riesgo previos a la cirugía ni tuvo predisposición en relación con la estirpe histológica, estadificación oncológica o recidiva tumoral

Objective: To determine the prevalence of arterial stump thrombosis (AST) after pulmonary resection surgery for lung cancer and to describe subsequent radiological follow-up and treatment. Material and methods: Observational, descriptive study of AST detected by computerized tomography angiography (CT) using intravenous contrast. Clinical and radiological variables were compared and a survival analysis using Kaplan-Meier curves was performed after dividing patients into 3 groups: patients with AST, patients with pulmonary embolism (PE), and patients without AST or PE. Results: Nine cases of AST were detected after a total of 473 surgeries (1.9%), 6 of them in right-sided surgeries (67% of AST cases). Median time to detection after surgery was 11.3 months (interquartile range 2.7-42.2 months), and range 67.5 months (1.4-69.0 months). Statistically significant differences were found only in the number of CTs performed in AST patients compared to those without AST or PE, and in tumor recurrence in PE patients compared to the other 2 groups. No differences were found in baseline or oncological characteristics, nor in the survival analysis. Conclusions: In this series, AST prevalence was low and tended to occur in right-sided surgeries. Detection over time was variable, and unrelated to risk factors previous to surgery, histopathology, and tumor stage or recurrence. AST had no impact on patient survival
