To gain insight into the trend of bacterial nanocellulose research, a bibliometric analysis was performed using the Science Citation Index Expanded database from 2005 to 2020. The study concentrated on the publication’s performance in terms of annual outputs and citations, mainstream journals, categories of the Web of Sciences, leading countries, prominent institutions, and trends in research. Current research priorities and future trends were analyzed after summarizing the most commonly used keywords extracted from words in the paper title analysis, authors’ keyword analysis, and KeyWords Plus. The findings revealed that the annual output in the form of scholarly articles on bacterial nanocellulose research steadily increased during the first quartile of the study period, followed by a very rapid increase in the last five-years of the study. Increasing mechanical strength would remain the main future focus of bacterial nanocellulose research to create its scope in different field of applications.

Background: Science Citation Index Expanded (SCIE) is one of the most important indexes that medical journals aspire to be covered by. Currently, SCIE indexes 14,840 peer-reviewed journals across 178 disciplines. Among these journals are 3445 medical journals, divided into more than 40 subject categories. Objectives: To reveal the impact and contribution of medical journals from Balkan countries through the Journal Impact Factor of those journals, the number of articles published by them, and the number of times those articles have been cited. Methods: Balkan countries are countries that fall or fully or partly within the Balkan peninsula. All medical journals from those countries listed in the SCIE were ranked based on cumulative citations between 2000 and 2020. Among them, the top 50 journals in terms of cumulative citations were chosen for the study, which analysed the data on 129,259 research articles and reviews that covered 27 different subject categories within the broad field of medicine. The countries were Bosnia & Herzegovina, Croatia, Greece, North Macedonia, Romania, Serbia, Slovenia, and Turkey Results: The top 50 journals included those published from eight Balkan countries. Turkey had the most journals (21) in the Web of Science (WoS) and Greece had 13 but, when ranked in terms of the number of journals in WoS per million people, Croatia topped the list, with 1.22 journals per million of its population, followed by Greece (1.21 journals). The top-cited journals were Anticancer Research (206,226 citations), International Journal of Oncology (171,654), Oncology Reports (157,467), Molecular Medicine Reports (82,009), and Oncology Letters (69,161). Oncology was the most cited subject category and Croatia, the country with maximum interaction with other Balkan countries, that is, papers in Croatian journals cited journals published from the maximum number of Balkan counties. Conclusion: The study provides insights into the last two decades of progress in academic publishing and in the performances of medical journals published from Balkan countries.

This study aimed to identify and analyze the characteristics of COVID-19 publications in the Science Citation Index Expanded published by Latin Americans in 2020. Documents including searching keywords in their title, abstract, or author keywords were assessed. The analyzed aspects covered characteristics of document types, languages, Web of Science categories, and journals. Publication performances of countries and institutions were evaluated by six publication indicators and two citation indicators. Results showed that a lower percentage of articles and a higher percentage of Spanish language were found. Web of Science category of general and internal medicine published the most articles. The Clinics was the most popular journal. The Cadernos de Saude Publica and Revista da Associacao Medica Brasileira published the most articles and reviews, respectively. Brazil took a leading position in the six publication indicators. The University of São Paulo in Brazil was the most productive institution. Based on the number of citations from the Web of Science Core Collection since publication to the end of 2020, 10 most frequently cited publications were presented. In addition, the analysis of words in publication titles, author keywords, and KeyWords Plus was performed to find the main research focuses.

Objectives: To estimate the frequency of data and code availability statements in a random sample of systematic reviews with meta-analysis of aggregate data, summarise the content of the statements and investigate how often data and code files were shared. Methods: We searched for systematic reviews with meta-analysis of aggregate data on the effects of a health, social, behavioural or educational intervention that were indexed in PubMed, Education Collection via ProQuest, Scopus via Elsevier, and Social Sciences Citation Index and Science Citation Index Expanded via Web of Science during a four-week period (between November 2nd and December 2nd, 2020). Records were randomly sorted and screened independently by two authors until our target sample of 300 systematic reviews was reached. Two authors independently recorded whether a data or code availability statement (or both) appeared in each review and coded the content of the statements using an inductive approach. Results: Of the 300 included systematic reviews with meta-analysis, 86 (29%) had a data availability statement and seven (2%) had both a data and code availability statement. In 12/93 (13%) data availability statements, authors stated that data files were available for download from the journal website or a data repository, which we verified as being true. While 39/93 (42%) authors stated data were available upon request, 37/93 (40%) implied that sharing of data files was not necessary or applicable to them, most often because "all data appear in the article" or "no datasets were generated or analysed". Discussion: Data and code availability statements appear infrequently in systematic review manuscripts. Authors who do provide a data availability statement often incorrectly imply that data sharing is not applicable to systematic reviews. Our results suggest the need for various interventions to increase data and code sharing by systematic reviewers.

The purpose of this scientometric study is to analyze the multiple sclerosis research in Science Citation Index-Expanded from 1992 to 2019 in order to determine the top features, trends, and topics. Articles related to multiple sclerosis in the section of title, abstract, keywords, and KeyWords Plus were retrieved from the Science Citation Index-Expanded and analyzed based on various indicators and characteristics. There was a significant increase in the number of articles from 408 in 1992 to 2756 in 2019. A sum of 42,112 articles related to multiple sclerosis has been published in 3,032 journals, which were classified among the 131 Web of Science categories. The top two categories were clinical neurology and neurosciences. Multiple Sclerosis Journal published the most articles. Articles published in the Neurology journal also had the highest citation per publication. Most of the articles were in English, while 23 other languages were used in the articles. Articles in Japanese and English with 7 and 6.9 authors have a higher average of authors than articles in other languages. English language articles received more citations than articles in other languages. The frequency of used keywords in title, abstract, author keywords, and KeyWords Plus analysis showed that “Therapy”, “disability”, “neurodegeneration”, “demyelination” and “MRI” show an increasing trend in the multiple sclerosis articles. The result of this study can help the policy makers and researchers realize the panorama of multiple sclerosis research and design future research.

Introduction: In contrast with other tropical countries, Cuba has been frequently studied from the point of views of scientometrics. It has been reported that Cuban researchers often failed to cite other Cuban researchers or to collaborate with them, and that 78 % of the Cuban scientifc output is published in Cuban journals and mostly missed by Scopus and the Web of Science. Objective: In this article, we analyze article characteristics (subject, language, authorship), institutions and journals that appear in the Science Citation Index Expanded, as well as citations from the Web of Science Core Collection. Methods: We analyzed publications from Cuba, dated 1900 to 2019, that reached the index. Results: We retrieved a total of 23576 publications, mostly articles. In this database, English is the dominant language, and, over time, articles have become longer and increased the number of authors and references. Numerically, the leading institution is Universidad de La Habana. Research is strongly concentrated around medical subjects. Collaboration teams lead by foreign authors have more citations recorded by the database, where the number of Cuban articles has decreased after 2008. Conclusion: For Cuban publications that reach the Science Citation Index Expanded (under 22%), most research is applied to health subjects and productivity has decreased in the last decade.

Background: Publication activity in the field of anesthesiology informs decisions that enhance academic advancement. Most previous bibliometric studies on anesthesiology examined data limited to journals focused on anesthesiology rather than data answerable to authors in anesthesia departments. This study comprehensively explored publication trends in the field of anesthesiology and their impact. We hypothesized that anesthesiology's bibliometric scene would differ based on whether articles in the same study period were published in anesthesiology-focused journals or were produced by authors in anesthesia departments but published in non-specialty journals.Methods: This cross-sectional study used bibliometric data from the Science Citation Index Expanded database between 1999 and 2018. Two datasets were assembled. The first dataset was a subject-dataset (articles published in 31 journals in the anesthesiology category of InCites Journal Citation Reports in 2018); the second dataset was the department-dataset (articles published in the Science Citation Index Expanded by authors in anesthesia departments). We captured the bibliographical record of each article in both datasets and noted each article's Institute for Scientific Information code, publication year, title, abstract, author addresses, subject category, and references for further study.Results: A total of 69,593 articles were published—cited 1,497,932 times—in the subject-dataset; a total of 167,501 articles were published—cited 3,731,540 times—in the department-dataset. The results demonstrate differences between the two datasets. First, the number of articles was stagnant, with little growth (average annual growth rate = 0.31%) in the subject-dataset; whereas there was stable growth (average annual growth rate = 4.50%) in articles in the department-dataset. Second, only 30.4% of anesthesia department articles were published in anesthesiology journals. Third, journals related to “pain” had the lowest department-subject ratio, which was attributable to a large portion of non-anesthesia department researchers' participation in related research.Conclusions: This study showed that articles published in anesthesiology-focused and non-specialty journals demonstrate fundamentally different trends. Thus, it not only helps researchers develop a more comprehensive understanding of the current publication status and trends in anesthesiology, but also provides a basis for national academic organizations to frame relevant anesthesiology development policies and rationalize resource allocation.

В статье анализируется развитие исследований, структура и динамика патентования научных результатов в области нанофотоники в период 2000–2020 годов. В центре внимания глобальный публикационный выход и вклад в него отдельных стран и их групп, тематическая структура исследований, показатели международной научной кооперации. Рассмотрен внутрироссийский исследовательский ландшафт, отмечено повышение роли географической периферии и университетов в его формировании. На примере базовых направлений нанофотоники показан сдвиг интереса от фотонных кристаллов к метаматериалам (как в исследованиях, так и в патентовании). В качестве источников информации использованы: библиографическая база данных Science Citation Index Expanded (SCIE) и база данных Ведомства по патентам и товарным знакам США (USPTO).
