Caracterización bibliométrica y temática de los grupos de investigación de Archivos de Bronconeumología (2003–2007)

Introduction

Scientific cooperation is essential for the advance of biomedical research. Scientists set up informal groups to work together on common issues, who are the main units in the research funding system. Bibliometric and Social Network Analysis methods allow informal groups in scientific papers to be identified and characterised. The objective of the study is to identify research groups in Archivos de Bronconeumología between 2003 and 2007 period with the aim of characterizing their scientific collaboration patterns and research areas.

Methods

Co-authorships, institutional collaboration relationships and the main research areas of papers published in Archivos de Bronconeumología have been identified. Co-authorship networks and institutional collaboration networks have been constructed by using Pajek software tool.

Results

A total of 41 research groups involving 171 investigators have been identified. The Collaboration Index for articles was 5.59 and the Transcience Index was 73.11%. There was institutional collaboration in 60.33% of papers. The collaboration between institutions of the same region prevails (41.03%), followed by collaborations between departments, services or units of the same institution (39.74%), inter-regional collaboration (14,97%) and international collaboration (6.83%). A total of 83.03% of articles were cited. The main research areas covered by groups were chronic obstructive pulmonary disease, asthma, lung neoplasm, bronchogenic carcinoma, smoking and pulmonary embolism.

Conclusions

The scientific production of a large number of Respiratory System Spanish research groups is published in Archivos de Bronconeumología. A notable collaboration and citation rate has been observed. Nevertheless, it is still essential to encourage inter-regional and international collaboration.     

Endoprothèses coronaires actives : respectons-nous les recommandations de la Société française de cardiologie et de la Haute Autorité de santé dans notre pratique quotidienne ?

Drug-eluting stents (DES) are known to dramatically reduce restenosis. However, they are more expansive than bare-metal stents (BMS) and they require prolonged dual antiplatelet therapy. In France, the French Society of Cardiology and the “Haute Autorité de santé” have defined recommendations for the use of DES (restricted to patients in high-risk group). The aim of this work was to evaluate our practice (whether these recommendations were well respected or not in our center). Between November 2007 and January 2008 then November 2008 and January 2009 we evaluated all Percutaneous Coronary Interventions (PCI). Two hundred and sixteen (216) patients (mean age 65 ± 13 years, 164 (76 %) were males and, 41 (19 %) were diabetics) had a PCI for stable angina or silent ischemia (47 %), unstable angina or acute coronary syndrome (ACS) ST− (26 %), ACS ST+ < 48 hours (24 %) or ACS ST+ > 48 hours−1 month (3 %). Two hundred and seventy six (276) stents were used, including 35 % of DES. The recommendations were well respected in 82 % of cases. However, 27 % of BMS were implanted in patients in whom DES were indicated. The French recommendations for DES are a reference to help practitioners, but they require to be adapted to each patient, depending on clinical state and their ability to be treated with prolonged dual antiplatelet therapy.
