These journals increased their impact metrics in the last 3 years, in parallel with the COVID pandemic. Conclusions Five official journals of European Internal Medicine societies, including Revista Clínica Española, meet high quality standards. (AU)

Bibliometric analyses of publications in the field of restless legs syndrome.

PURPOSE: Restless Legs Syndrome (RLS) is a chronic neurological disorder and the incidence of RLS is a more common disease than known is accepted. This study was performed to identify and analyze the characteristics of RLS-related articles published from 2001 to 2020 using bibliometric analyses. METHODS: RLS-related articles published from 2001 to 2020 were retrieved from the Web of Science Core Collection database with predefined search terms. VOSviewer software was used to visualize various bibliographic coupling networks on data. The top 10 lists (about organizations, papers, journals, most commonly cited articles, authors, countries, and keywords) extracted from 2001 to 2020 were also analyzed. RESULTS: A total of 2311 articles were included and the total number of publications from 2001 to 2020 was increased by 5.02-fold. The highest number of RLS publications (n = 171) since 2001 was observed in 2020. The United States is contributed the highest number of RLS-related publications (34.53%). The top productive journal was Sleep Medicine and the most prominent organization was Johns Hopkins University. In the list of top 10 authors, Allen RP was the first author. CONCLUSIONS: This study is the first bibliometric analysis that provides a general perspective on the RLS from 2001 to 2020 and may be useful as a guide for further research in this field.

Social media usage to share information in communication journals: An analysis of social media activity and article citations.

Social media has surrounded every area of life, and social media platforms have become indispensable for today's communication. Many journals use social media actively to promote and disseminate new articles. Its use to share the articles contributes many benefits, such as reaching more people and spreading information faster. However, there is no consensus in the studies that to evaluate between tweeted and non-tweeted papers regarding their citation numbers. Therefore, it was aimed to show the effect of social media on the citations of articles in the top ten communication-based journals. For this purpose, this work evaluated original articles published in the top 10 communication journals in 2018. The top 10 communication-based journals were chosen based on SCImago Journal & Country Rank (cited in 2019). Afterward, it was recorded the traditional citation numbers (Google Scholar and Thompson-Reuters Web of Science) and social media exposure of the articles in January 2021 (nearly three years after the articles' publication date). It was assumed that this period would allow the impact of the published articles (the citations and Twitter mentions) to be fully observed. Based on this assessment, a positive correlation between exposure to social media and article citations was observed in this study.

Tracking changes between preprint posting and journal publication during a pandemic.

Amid the Coronavirus Disease 2019 (COVID-19) pandemic, preprints in the biomedical sciences are being posted and accessed at unprecedented rates, drawing widespread attention from the general public, press, and policymakers for the first time. This phenomenon has sharpened long-standing questions about the reliability of information shared prior to journal peer review. Does the information shared in preprints typically withstand the scrutiny of peer review, or are conclusions likely to change in the version of record? We assessed preprints from bioRxiv and medRxiv that had been posted and subsequently published in a journal through April 30, 2020, representing the initial phase of the pandemic response. We utilised a combination of automatic and manual annotations to quantify how an article changed between the preprinted and published version. We found that the total number of figure panels and tables changed little between preprint and published articles. Moreover, the conclusions of 7.2% of non-COVID-19-related and 17.2% of COVID-19-related abstracts undergo a discrete change by the time of publication, but the majority of these changes do not qualitatively change the conclusions of the paper.

The most influential articles on kidney transplantation: A PRISMA-compliant bibliometric and visualized analysis.

BACKGROUND: Kidney transplantation (KT) has become common in the treatment of end-stage renal disease. However, to date, there have been no bibliometric analyses of KT research to identify the most influential articles. The purpose of this research is to identify and characterize the 100 most cited articles that focus on KT and to clarify the trends in the accomplishments in this field. METHODS: We searched the Thomson Reuters Web of Science citation indexing database and used keyword mapping of VOSviewer. The top 100 most cited manuscripts were analyzed based on their titles, authors, institutions, countries of origin, years of publication, and topics. RESULTS: The New England Journal of Medicine has published the most manuscripts on kidney transplantation (n = 26) and is the most cited journal (n = 15,642). The United States has the highest number of publications (n = 61). Kashika is the corresponding author with the most published papers (n = 5; 2892 citations). The most common topics of publication are immunosuppressant (n = 34), clinical outcome (n = 26), and pathology (n = 22). Keywords related to immunosuppressant are the most common in keyword mapping with VOSviewer. CONCLUSIONS: This bibliometric analysis of KT research provides the research characteristics and publication trends of this topic. In KT research, immunosuppressants and post-transplant clinical outcomes have been important topics.

How Diverse Is Medicinal Chemistry? Insights into Race, Ethnicity, Origin, Gender, and Geography.

A bibliometric study of authors across medicinal chemistry journals over 20 years reveals important trends. Most United States (US) based authors are assigned as racially/ethnically Asian or White; few are Black or Hispanic. More US coauthors have the same race/ethnicity as the corresponding author than expected. The percentage of female authors increased globally, but only slowly. Since 2010, the number of female and male authors declined by 9% and 30%, respectively. Geographically, most authors are male except in Italy where there is gender balance. Gender homophily is observed globally. Geographically, the discipline is now more widely practiced. Article output doubled from 2000 to 2010 with a large increase in articles from China. China excepted, output has since declined. The average number of authors per article rose by a third since 2000. The value of high diversity groups in education, research, and industry cannot be overstated. We recommend diversity is addressed by every medicinal chemist.

Understanding the literature: Complexity of statistical methods used in high-impact cardiothoracic surgery research.

OBJECTIVE: Biostatistics are frequently used in research published in the domain of cardiothoracic surgery. The objective of this study was to describe the scope of statistical techniques reported in the literature and to highlight implications for editorial review and critical appraisal. METHODS: Original research articles published between January and April 2017 in the Journal of Thoracic and Cardiovascular Surgery, Annals of Thoracic Surgery, and the European Journal of Cardio-Thoracic Surgery were examined. For each article, the statistical method(s) reported were recorded and categorized by complexity. RESULTS: We reviewed 293 articles that reported 1068 statistical methods. The mean number of different statistical methods reported per article was 3.6 ± 1.9, with variation by subspecialty and journal. The most common statistical methods were contingency tables (in 59% of articles), t tests (49%), and survival methods (49%). Only 4% of articles used descriptive statistics alone. An introductory level of statistical knowledge was deemed sufficient for understanding 16% of articles, whereas for the remainder a higher level of knowledge would be needed. CONCLUSIONS: Contemporary cardiothoracic surgery research frequently requires the use of complex statistical methods. This was evident across articles for all cardiothoracic surgical subspecialties as reported in 3 high-impact journals. Routine review of manuscript submissions by biostatisticians is needed to ensure the appropriate use and reporting of advanced statistical methods in cardiothoracic surgery research.

Top 100 influential manuscripts in obstructive sleep apnea: a bibliometric analysis.

OBJECTIVE: This study aimed to explore the characteristics of the top 100 influential manuscripts on obstructive sleep apnea (OSA). METHODS: All manuscripts in English were searched from the Thomson Reuters Web of Science database by using OSA-related terms and ranked based on citation frequency. The top 100 influential manuscripts were selected and further analyzed by author, subject, journal, year of publication, country of origin, and institution. RESULTS: A total of 42,878 manuscripts were searched from the Web of Science. The top 100 influential manuscripts were published from 2005 to 2017, with a total citation frequency of 38,463 and a median citation frequency of 303 (range: from 210 to 2, 707). The American Journal of Respiratory and Critical Care Medicine published the largest number of manuscripts from the top 100 (n = 18; 5340 citations), followed by Sleep (n = 11; 3516 citations) and Chest (n = 7; 1784 citations). The most cited manuscript (Marin, J.M et al., Lancet 2005; 2707 citations) mainly analyzed long-term cardiovascular outcomes in men with OSA with/without continuous positive airway pressure. The most prevalent subject was associated diseases (n = 41), followed by treatments (n = 40). Most of the manuscripts were original articles (n = 63) based on observational clinical studies and published from American institutions (n = 60). CONCLUSIONS: Our study identified the top 100 influential manuscripts on OSA and provides insights into the characteristics of the most highly cited manuscripts to improve our understanding and management of OSA.

Contribution of Arab Countries to Familial Mediterranean Fever Research: a PubMed-based bibliometric analysis.

Familial Mediterranean Fever (FMF) is an inherited autoinflammatory disease. One of the feared complications of FMF, amyloidosis is often correlated with an increased mortality rate. The severity of the disease is linked with different mutations in the MEFV gene that may favor different outcomes (amyloidosis, Bechet's disease…). Although several countries worldwide contribute remarkably to research related to FMF, Arab countries make up only a small part of this contribution. This study aims to estimate numerically the contribution of the Arab world to research conducted on FMF. PubMed is used to quantitate the number of FMF-related articles published by each Arab country from 2004 till 2019. The retrieved numbers are normalized with respect to each country's average population and average Gross Domestic Product (GDP) and are also compared to those of some non-Arab countries having high FMF prevalence. In comparison with some non-Arab countries, the Arab world has a minor contribution of 3.80% to the total FMF-related publications, faced by 24.93% solely by Turkey. Out of total research done by Arab countries, FMF-related articles constitute no more than 0.133%. When normalized against the average population, Tunisia ranks first, followed by Lebanon. Similarly, normalizing the retrieved numbers of articles against average GDP shows that Tunisia and Lebanon come first and second, respectively. Only 8 Arab countries published a total of 13 articles concerning amyloidosis which makes 4.7% of the total Arabic FMF published articles. This study reflects an undoubtable need for more research to be conducted on FMF by the Arab countries, which suffer greatly from immense shortage in research productivity, due to the many obstacles and limitations these countries face every day.

Contribution of Arab countries to Behçet disease research: a PubMed-based bibliometric and altmetric analysis.

Behçet's disease (BD), a rare multisystemic disorder, has an unknown etiology. Interactions between genetic and environmental factors play a major role in this disorder. Human leukocyte antigen B51 allele is the strongest risk factor for the development of Behçet disease. The high prevalence of BD in the Arab world makes it necessary to undergo local research and publications, to target particular genetic, geographical, or even cultural risk factors. This study aims to assess the numerical contribution of the Arab world to research on Behçet disease. Using the PubMed platform, the number of BD-related publications from 2005 to 2019 was assessed for all 22 Arab countries, and countries having the highest prevalence of the disease. Number of publications on BD was normalized to the average population size and GDP for each Arab country. From 2005 to 2019, Arab countries published 198 articles related to BD. This accounts for 0.1% of the total number of BD-related articles published in this period (4170). A significant, positive correlation of moderate strength exists between the number of publications and the average population, while a non-significant, positive correlation of week strength exists between the number of publications and GDP. Concerning the top 15 countries according to Behçet disease prevalence, Turkey had the greatest number of articles, while the USA had the highest ratio of publications per prevalence. The high prevalence of BD in Arabic countries was faced by paradoxically low research activity in this field. Arab countries are lagging behind in the field of Behçet disease-related research, which highlights the need for improving research productivity.
