Trends in Pleural Effusion Research

Abstract

Background: Research in pleural diseases has traditionally been neglected but is now growing. Objectives: This study aimed to analyze scientific research trends on pleural effusions over the last decades. Method: We conducted a bibliometric analysis of the Scopus database from its inception to March 2016, searching for original articles and reviews on ''pleural effusion'' (key word). Journal, year of publication, number of citations, authors and their affiliations, and the Hirsch (H)-index for some of these variables were recorded and analyzed. Results: A total of 15 982 documents were retrieved, of which half have been published in the last 18 years and a quarter during the last 8 years. Chest ranked first regarding the number of documents on pleural effusions (both absolute number and yearly rate) and their scientific relevance (H-index of 76). The United States had contributed the most to pleural research productivity (23%). American pulmonologists Dr Richard Light and Dr Steven Sahn exhibited the highest number of papers (206 and 156, respectively) and author H-indexes (44 and 38, respectively). Conclusion: There is growing research activity in the field of pleural effusions, which has gained relevance and visibility in clinical respiratory journals. The United States is the leader in quantity and quality of research productivity in pleural medicine.

Global trends in research related to social media in psychology: mapping and bibliometric analysis

“…Furthermore, most of the social networking sites were established and founded in the USA. These findings are similar to those found in previous bibliometric studies in different fields, principally that the USA had the highest activity in scientific research output worldwide and in international collaboration networks, as well as the highest h-index [32,[35][36][37]. Regarding the international collaboration, this emphasizes the significance of global networking and its impact on research output [38][39][40][41].…”

“…The correlation analysis clearly shows a high correlation between the number of publication in the field of social media and the publication productivity related to social media in psychology (r = 0.995; p value < 0.001). This increase in publications related to social media in psychology seems to be related to (1) social networking sites, which became very popular in previous decade [25,26]; (2) increasing interest in this field in multiple health disciplines [27][28][29][30][31]; (3) or general cause such as the increasingly prevalent use of the internet, which has allowed more rapid distribution of medical knowledge through scientific research [32]. Table 1 shows information about the 10 countries with the most published papers.…”

Análisis bibliométrico de las publicaciones peruanas relacionadas a resistencia antimicrobiana en SCOPUS (1992-2017)

“…La recolección de datos para este estudio se llevó a cabo utilizando la base de datos Scopus ya que es reconocida como la base de datos de citas y resúmenes más grande de la literatura revisada por pares y que cubre una amplia gama de temas (21) . Asimismo, ha sido utilizada previamente como única fuente de datos en artículos bibliométricos relacionados a antimicrobianos (22)(23)(24) .…”

“…La estrategia de búsqueda fue similar a la descrita en estudios publicados anteriormente (23)(24)(25)(26)(27)(28)(29) . Las palabras clave empleadas para la recolección de datos se obtuvieron de artículos publicados sobre resistencia antimicrobiana que aparecen en Scopus (21) .…”
