Cardiovascular Scientific Production in Spain and in the European and Global Context (2003-2007)

Introduction and objectives The publication of research articles has increased considerably in recent years in all biomedical fields. The present study examines the position of Spanish quality research in cardiology in the European and world context, and its evolution during the 5-year period 2003-2007. Methods Using the Science Citation Index Expanded of Thomson Reuters as data source, we compared Spanish cardiovascular scientific production with that of the rest of countries in the European Union and of the most important countries worldwide, along with relative productivity as per number of inhabitants and Gross Domestic Product, and the number of citations in the journals of the Cardiac…

Global mapping of randomised trials related articles published in high-impact-factor medical journals: a cross-sectional analysis

[Background]: Randomised controlled trials (RCTs) provide the most reliable information to inform clinical practice and patient care. We aimed to map global clinical research publication activity through RCT-related articles in high-impact-factor medical journals over the past five decades.

Fumador, exfumador y COVID-19: la nicotina no protege contra el SARS-CoV-2

Queremos agradecer a Moril et al.1 el interés en nuestro trabajo, pues nos permite reflexionar sobre el tema. La proteína Spike del SARS-CoV-2 es la responsable de facilitar su entrada a las células humanas, requiriendo cebado por la proteasa TMPRSS2 que permite la fusión de las membranas viral y celular2. El receptor utilizado por la proteína Spike es la enzima convertidora de angiotensina 2 (ACE2)2, que se expresa en diferentes estirpes celulares, además de en el pulmón; existiendo, a nivel pulmonar, un gradiente de expresión de ACE2 (mayor expresión en vías respiratorias superiores [epitelio nasal] y menor en los neumocitos alveolares)2. Se sugiere que una mayor expresión de ACE2 podría …

The use of gamification in education: a bibliometric and text mining analysis

The use of games in education represents a promising tool to motivate and engage students in their learning process. Most of previous research on the topic has focused to develop theoretical frameworks or to conduct experiments as a means to analyse learning outcomes such as knowledge retention, problem-solving skills gains or attitudes toward game-based learning. Nevertheless, little research has focused on providing a comprehensive literature review, which will help researchers to better understand how this stream of research has evolved over the last years. In this study, we use a bibliometric, social network and text mining analysis in order to provide useful up-to-date information to p…

Gender differences in original Archivos de Bronconeumología publications, 2001-2018

Abstract 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 Bronconeumologia (AB). Methods We performed a bibliometric study of articles published in AB between 2001 and 2018. Author gender was analyzed in four scenarios: first author, last author, middle authors, and mentee authors. Comparisons were made by authors’ specialties, funding received, multicenter studies, specialist areas, and others. Multivariate models adjusted for the percentage of registered physicians in the Spanish health s…

Analysis of scientific production in spanish implantology

Background The aim of the study was to quantify the scientific productivity of researchers, organizations, and regions in Spain that publish articles on implantology in dental journals indexed in Journal Citation Reports. Material and Methods A search was conducted among the core collection of Thomson Reuters’ Web of Science database, on the basis of its broad thematic and geographic coverage of health sciences. The search identified original articles – the main vehicle for the dissemination of research results. The search was conducted in July 2016, applying the truncated search term ‘implant*’ to locate original articles on implantology and its derivative forms. The search was conducted w…
