Coronavirus and COVID-19: The latest news and views from the scientific community about the new coronavirus and COVID-19.

Introduction: Coronavirus is a family of viruses that cause respiratory infections. The new coronavirus agent was discovered on 12/31/19 after cases registered in China. It causes the disease called coronavirus (COVID-19). The first human coronaviruses were isolated for the first time in 1937. However, it was in 1965 that the virus was described as coronavirus, due to the profile under microscopy, looking like a crown. Objectives: This article aims to bring the most current medical literature on the coronavirus pandemic (COVID-19). Methodology: The publications with the greatest impact factor in February and March 2020 were searched in Nature, Elservie, JAMA and Wiley. Results: More than 200 articles on COVID-19 were found and 20 articles were selected with the highest number of citations on Google Scholar. Conclusion: Until March 2020, there is no really effective treatment against COVID-19, but many medications are being tested and with very promising results. The concern with the economy is also an extremely relevant factor at this moment.

Abstract We define a Landmark Paper Index (LPI), calculate and analyze indices for all papers published in rheological journals (‘η-journals’) between 1990 and 2006. This paper offers some information about the criteria influencing the impact of publications on the (scientific) community. In opposite to the well known Impact Factor (journal sensitive) or the number of citations (article sensitive, publication year insensitive) the LPI helps to identify established and potential breakthrough contributions by considering the number of citations per year after publication, in a way which does not overestimate the few, highly cited, articles when performing averages. We discuss the effect of formal criteria on the LPI.

BackgroundWe examined citation data for the British Journal of Psychiatry (BJP) and four other general psychiatry journals to assess their impact on the scientific community.MethodData on three measures of citations (total number of citations, impact factor and ranking by impact factor) were obtained from Journal Citation Reports for 1985–1994. Rank correlations from year to year were calculated.ResultsThe BJP currently ranks sixth of all psychiatry journals when journals are ranked by impact factor. The journal's impact factor fell between 1985 and 1990 and this was followed by a rise in impact factor after 1991. The BJP did not rank in the top 10 psychiatry journals between 1991 and 1993. Archives of General Psychiatry is cited more frequently than any other psychiatry journal, with the American Journal of Psychiatry usually ranking second. Psychopharmacology journals are replacing more general journals in the top rankings. Rankings of most journals have become less stable in recent years.ConclusionsThe BJP would have to change the nature and number of papers published to improve its impact factor. There are a number of limitations to citation data and such data are only one of several factors useful in evaluating the importance of a journal's contribution to scientific and clinical communities.Conflict of interestThese condauthor is Editor of the British Journal of Psychiatry.
