TY - JOUR T1 - International scientific communications in the field of chronic bronchitis and pulmonary emphysema JF - European Respiratory Journal JO - Eur Respir J VL - 44 IS - Suppl 58 SP - P2804 AU - Kosta Kostov Y1 - 2014/09/01 UR - http://erj.ersjournals.com/content/44/Suppl_58/P2804.abstract N2 - The dynamic internationalization of research in the multidisciplinary field of chronic bronchitis and pulmonary emphysema, two related diseases within chronic obstructive pulmonary disease was analyzed. A retrospective problem-oriented search on this topic was performed in Web of Science (WoS) and Scopus in 1994-2013. The following scientometric parameters were studied: number of abstracted publications; names of authors; languages and types of primary documents; titles, number, and thematic profile of journals, and nominations, thematic profiles and countries of authors' institutions. Selected citation data in WoS were retrieved, too.In WoS, there were 761 items by authors from 51 countries and in Scopus - 1298 ones by authors from 63 countries. In WoS, most papers were abstracted in 2012 (61), 2008 (58) and 2013 (54) but in Scopus, there were 93, 85 and 100 ones, respectively. E. K. Silverman presented with most abstracted publications in WoS but A. G. N. Agusti did in Scopus. In WoS, primary publications were in 10 and in Scopus in 24 languages. Articles prevailed followed by reviews and proceedings papers. Chest, Am J Respir Crit Care Med and Eur Resp J contained most papers on this topic. In WoS, 761 papers received 20911 citations without self-citations. There were 13804 citing articles without self-citations as 658 papers were cited at least once. Average citations per item were 29.16 and h-index was 75. The paper by J. C. Hogg et al. (N Engl J Med, 350, 2004, 2645-2653) received 1184 citations or 107.64 per year.The files with abstracts analyzed through this constellation of scientometric indicators could contribute to further improvement of international collaboration.
