B - Citation-related characteristics in scientific journals

Sangwal K. Some citation-related characteristics of scientific journals published in individual countries. Scientometrics 2013;97:719-741
(doi: 10.1007/s11192-013-1053-1)

This bibliometric study on relationships between publication language, impact factors and self-citations of journals published in individual countries, eight from Europe and one from South America (Brazil) found that: English-language journals, as a rule, have higher impact factors than non-English-language journals; all countries investigated have journals with very high self-citations but the proportion of journals with high self-citations with reference to the total number of journals published in different countries varies enormously; irrespective of the publication language, journals devoted to very specialized scientific disciplines have high self-citations.

B - Impact of article language in medical journals

Diekhoff T, Schlattmann P, Dewey M. Impact of article language in multi-language medical journals - a bibliometric analysis of self-citations and impact factor. PLoS One 2013;8(10):e76816
(doi: 10.1371/journal.pone.0076816)

This article analyzed the influence of English-language articles in multi-language medical journals. The findings suggested that a larger share of English articles in multi-language medical journals is associated with greater international visibility and recognition. Fewer self-citations were found as they are not needed to artifactually increase the impact factor. with a greater share of original articles in English.

B - Open access respiratory journals

Open access (OA) journals benefit researchers and the general public by promoting visibility, sharing and communicating. Non-mainstream journals should turn the challenge of OA into opportunity of presenting best research articles to the global readership. The authors found that OA respiratory journals have relative higher acceptance rate and less time between submission and final publication than conventionally published journals. OA respiratory journals need to optimize their business models to promote the healthy and continuous development.

B - How to read health care news stories

Schwitzer G. A guide to reading health care news stories. JAMA Internal Medicine e-pub May 05, 2014
(doi: 10.10001/jamainternmed.2014.1359)

A team of reviewers from evaluated the reporting by US news organizations on new medical treatments, tests, products, and procedures. They graded most stories unsatisfactory on 5 of 10 review criteria: costs, benefits, harms, quality of the evidence, and comparison of the new approach with alternatives. They established that the stories often emphasize or exaggerate potential benefits, minimize or ignore potential harms, and ignore cost issues. These findings can help journalists improve their news stories and help physicians and the public better understand the strengths and weaknesses of news media coverage of medical and health topics.
