Environmental risk factors of systemic sclerosis

International audienceSystemic sclerosis (SSc) has a complex pathogenesis. Although, there is a growing evidence that environmental factors have an impact on alterations and modulation of epigenetic determinants, resulting in SSc onset and progression. A marked correlation has thus been found between SSc onset and occupational exposure to crystalline silica and the following organic solvents: white spirit, aromatic solvents, chlorinated solvents, trichloroethylene, and ketones; the risk associated with high cumulative exposure to silica and organic solvents further appears to be strongly increased in SSc. Altogether, occupational exposure should be systematically checked in all SSc patients at diagnosis, as (1) exposed patients seem to develop more severe forms of SSc and (2) the identification of the occupational agents will allow its interruption, which may lead to potential improvement of SSc outcome. By contrast, based on current published data, there is insufficient evidence that exposure to other chemical agents (including notably pesticides as well as personal care such as silicone and hair dye), physical agents (ionizing radiation, ultraviolet radiation, electric and magnetic fields), and biological agents (infections and diet, foods, and dietary contaminants) is a causative factor of SSc. Further investigations are still warranted to identify other environmental factors that may be associated with SSc onset and progression

Reliability of citations of medRxiv preprints in articles published on COVID-19 in the world leading medical journals

International audienceIntroduction Preprints have been widely cited during the COVID-19 pandemics, even in the major medical journals. However, since subsequent publication of preprint is not always mentioned in preprint repositories, some may be inappropriately cited or quoted. Our objectives were to assess the reliability of preprint citations in articles on COVID-19, to the rate of publication of preprints cited in these articles and to compare, if relevant, the content of the preprints to their published version. Methods Articles published on COVID in 2020 in the BMJ, The Lancet, the JAMA and the NEJM were manually screened to identify all articles citing at least one preprint from medRxiv. We searched PubMed, Google and Google Scholar to assess if the preprint had been published in a peer-reviewed journal, and when. Published articles were screened to assess if the title, data or conclusions were identical to the preprint version. Results Among the 205 research articles on COVID published by the four major medical journals in 2020, 60 (29.3%) cited at least one medRxiv preprint. Among the 182 preprints cited, 124 were published in a peer-reviewed journal, with 51 (41.1%) before the citing article was published online and 73 (58.9%) later. There were differences in the title, the data or the conclusion between the preprint cited and the published version for nearly half of them. MedRxiv did not mentioned the publication for 53 (42.7%) of preprints. Conclusions More than a quarter of preprints citations were inappropriate since preprints were in fact already published at the time of publication of the citing article, often with a different content. Authors and editors should check the accuracy of the citations and of the quotations of preprints before publishing manuscripts that cite them

Bibliometric research in Occupational Health (editorial)

Bibliometrics is the use of mathematical techniques to investigate publishing and communication patterns in the distribution of information. There is now growing evidence to suggest that the entire bibliometric approach might be significantly modified in the near future, in all fields of medicine including occupational health, via the metamorphosis of scientific communications, such as open-access, online-only periodicals, or even sharing scientific knowledge without the use of traditional periodicals. It will be interesting to see what impact such changes might have in the field of occupational health
