Top 100 cited articles on diabetes mellitus and Covid-19: A bibliometric analysis.

Karthik Vishwanathan, Srinivas B S Kambhampati, Raju Vaishya.

   AIMS: There is a lack of bibliometric analytical studies on Diabetes Mellitus in Covid-19. As diabetes mellitus is a common co-morbidity associated with poor outcomes in Covid-19, we undertook a bibliometric analysis of the top 100 publications relating to this subject.
METHODS: The top 100 cited papers were searched on Pubmed. Information about authors, month and year of publication, name of the journal, country of the affiliating institute of the first author, affiliation, total citations, citation density, type of study, type of paper, nature of the study, collaborations, number of affiliations and erratum details were collected.
RESULTS: The top 100 papers were published in 57 journals and were cited 53,374 times. Though most of the top 100 papers were written by first authors affiliated to institutes in the United States, the publication from China were the most influential. Two institutions from the United States had the highest number of affiliations of the first author. The Lancet was the most productive journal with the highest number of total citations (24,221).
CONCLUSIONS: This study gives valuable information to academicians and researchers regarding trends in the publication of the most influential articles on diabetes mellitus and Covid-19 infection.

Performance of highly cited multiple sclerosis publications in the Science Citation Index expanded: A scientometric analysis.

Yuh-Shan Ho, Maryam Shekofteh.

   BACKGROUND: The present study aims to identify and analyze the characteristics of highly cited publications on Multiple sclerosis in the Science Citation Index Expanded.
METHODS: Documents that had 100 citations or more were considered as the highly cited documents. Highly cited publications were analyzed in the distribution of document types, languages, publication years, Web of Science categories, and journals as well as publication performance of countries, institutions, and authors. The six and five publication indicators were applied to compare publications of the countries and the institutes respectively. Highly cited authors were analyzed by Y-index.
RESULTS: In general, articles spent about 12 years to be highly cited articles. The USA dominated the production by the six publication indicators. Harvard University was the most active in research on multiple sclerosis while the University of California, Los Angeles in the USA shows the most independent research. M. Filippi was recognized as the most productive author who had the most articles as the corresponding author.
CONCLUSION: The findings may be of interest to multiple sclerosis researchers and policymakers all around the world.

Medical professionalism research characteristics and hotspots: a 10-year bibliometric analysis of publications from 2010 to 2019.

Xinzhi Song, Nan Jiang, Honghe Li, Ning Ding, Deliang Wen.

  An abundance of publications on medical professionalism have been published in recent years. Our study aimed to analyze the external characteristics of publications on professionalism using bibliometrics, to describe its current developments and trends, and to explore professionalism research hotspots using co-word analysis. We retrieved literature on professionalism published from 2010 to 2019 from the Web of Science database. Histcite and CiteSpace were used to analyze external characteristics of publications, including publication trends and distributions of publications by country/region, institution, author, and journal. Co-word analysis was conducted to analyze research hotspots, using the Bibliographic Item Co-Occurrence Matrix Builder and Graphical Clustering Toolkit. We constructed a strategic diagram to show the state of each research hotspot and the relationship between the various hotspots in this field. Results showed publications on professionalism increased in number year by year as a whole. The USA, including its institutions and authors, maintained the top position worldwide in terms of numbers of publications and citations. Among scholarly journals, Academic Medicine has published more articles and has had higher citations per paper than any other journal. Six research hotspots on professionalism were identified, visualized, and expounded. Of these, the theme of "measurement and evaluation of clinical competence" received the most attention in the field of professionalism. The reporting of quantifiable knowledge on the characteristics and research hotspots of publications could help inform gaps in the field of medical professionalism and provide evidence and guidance for future work for researchers, physicians, and educators.

Bibliometric analysis of international publication trends in impacted third molar surgery research (2000-2020).

Y Balel.

  In scientific fields, various methods of statistical analysis such as bibliometric analysis have been used to determine the effectiveness of journals, research, and articles. The aim of this study was to conduct a bibliometric analysis to systematically and understandably characterise publications on impacted third molar surgery (ITMS) from 2000 to 2020. The articles were retrieved on the same day (1 January 2021) from the Web of Science Core Collection (WoSCC) database of the Web of Science to prevent bias due to daily updates of the databases. A total of 3326 publications from 2000 to 2020 were analysed. The United States of America (USA) had the highest number of publications and h-index value. The highest number of co-citations were of Pell GJ. ITMS research was collected under nine 'clusters'. In this study, developments, the most influential publications, journals, and countries in the research of ITMS were determined based on the evidence gained through bibliometric analysis.

Influential and Highest Cited Shoulder Instability Articles: A Bibliometric Analysis.

Sachin Allahabadi, Ava Eftekhari, Sonali E Feeley, Brian T Feeley, Drew A Lansdown.

   Background: In orthopaedic surgery and other fields, the effect of influential journal articles has been evaluated by their citation counts and their correlation with methodological quality.
Purpose: To identify and characterize the 50 most cited articles on shoulder instability, examine trends in publication characteristics, and evaluate the correlation of citations with quality of evidence.
Study Design: Cross-sectional study.
Methods: The Web of Science and Scopus online databases were searched to identify the top 50 most cited articles on shoulder instability, based on the average number of citations from each database. Article characteristics were recorded, and level of evidence and methodological quality were assessed using the modified Coleman Methodology Score (mCMS), Jadad scale, and Methodological Index for Non-Randomized Studies (MINORS). Spearman correlation was used to evaluate relationships between citations or citation density (citations/y) and level of evidence or methodological scoring. Top cited articles from recent years were also aggregated.
Results: The top 50 most cited papers had a mean ± SD number of citations of 381.5 ± 166.7, with a mean of 15.0 ± 8.8 citations/y. Overall, 15 articles (30%) were biomechanical/cadaveric studies, and 15 (30%) were case series. Only 3 (6%) were considered to have level 1 evidence. The mean ± SD mCMS was 54.4 ± 12.7, mean ± SD Jadad score was 3.1 ± 1.4, and mean ± SD MINORS score was 10.5 ± 3.3. There were no significant correlations between citation rank or density and methodological assessments. There were weak correlations between citation rank and publication year (r s = 0.32; P = .022) and between rank and level of evidence (r s = -0.38; P = .047). The correlation between citation density and publication year was moderate (r s = 0.70; P < .0001). There was no difference in citation density of the top 10 articles from 2010 to 2020 compared with the top 10 from the overall list (23.8 ± 5.3 vs 28.8 ± 9.5; P = .16).
Conclusion: Influential articles in shoulder instability included a high proportion of biomechanical/cadaveric studies. The majority of top cited articles had lower evidence levels and poorer methodological quality without strong correlation with citations or citation density. There was a moderate correlation between citation density and year of publication.

Ourlad Alzeus G Tantengco, Inah Marie C Aquino, Joannes Luke B Asis, Joanne Jennifer E Tan, Mary Nadine Alessandra R Uy, Elizabeth P Pacheco.

   AIMS: To determine the characteristics and trends of published articles in the field of gestational diabetes mellitus (GDM) in Southeast Asia (SEA) through a bibliometric analysis.
METHODS: Systematic review of literature on GDM in SEA countries was performed using the Ovid MEDLINE®, Scopus, and WPRIM databases between 1975 and 2020. All published studies on GDM conducted in or published by authors from any SEA country were included in our analysis. Bibliometric information was obtained from Scopus and bibliometrics diagrams were created using VOSviewer software.
RESULTS: A total of 322 articles were obtained in this study. The number of publications showed an upward trend starting 2011. The country with the greatest number of publications was Malaysia while The National University of Singapore was the most productive institution in GDM research in SEA. The focus of GDM research in SEA were on the prevalence, prevention, diagnosis, and pregnancy outcomes. GDP, research expenditure, and researchers per million people were positively correlated with research productivity and impact in GDM research in SEA.
CONCLUSIONS: This is the first bibliometric analysis on GDM in SEA countries. GDM research in SEA continued to increase in the past years but still lagged behind that of other regions. The SEA countries should consider increasing support for research to produce substantial research that can serve as basis for evidence-based and locally applicable GDM interventions.

Meng Li, Qiang Cai, Jing-Wen Ma, Li Zhang, Claudia I Henschke.

   Background: The number of citations of an article reflects its impact on the scientific community. The aim of this study was to identify and characterize the 100 most cited articles on lung cancer screening.
Methods: The 100 most cited articles on lung cancer screening published in all scientific journals were identified using the Web of Science database. Relevant data, including the number of citations, publication year, publishing journal and impact factor (IF), authorship and country of origin, article type and study design, screening modality, and main topic, were collected and analyzed.
Results: The 100 most cited articles were all English and published between 1973 and 2017, with 81 published after 2000. The mean number of citations was 292.90 (range 100-3,910). Sixty articles originated from the United States. These articles were published in 32 journals; there was a statistically significant positive correlation between journal IF and the number of citations (r=0.238, P=0.018). Seventy-nine articles were original research of which 37.9% were about results from randomized controlled trials (RCTs). The most common screening modalities in these articles were low-dose computed tomography (LDCT) (n=78), followed by chest X-ray radiography (CXR) and sputum cytology (n=11). The most common topic in these articles was screening test effectiveness.
Conclusions: Our study presents a detailed list and analysis of the 100 most cited articles published about lung cancer screening which provides insight into the historical developments and key contributions in this field.

Orthognathic Surgery: A Bibliometric Analysis of the Top 100 Cited Articles.

Ricardo Grillo.

PURPOSE: An increasing number of articles on orthognathic surgery are published every year. This paper aims to provide a list of the top 100 cited articles on orthognathic surgery to help any professional level with interest in this topic and to map the trends of orthognathic surgery publications over time.
METHODS: A bibliographic search (retrospective study) following STROBE guidelines was performed on Google Scholar (GS) and Dimensions with the term "orthognathic surgery" in the title, abstract, and keywords. The number of citations, citations per year, authors, and publication year were evaluated. A ranking was created in GS citations order with the top 100 cited articles and variables discussed individually. A graphical illustration of keywords was created using VOSviewer. These steps are fundamental in creating this list and relating it to all published articles on the topic.
RESULTS: A helpful list of the top 100 articles was developed to help professionals in entirely different manners. Virtual planning and complications in orthognathic surgery were the most cited topics, with a 95% confidence interval (P < .05). Some curiosities are discussed, such as increasing interest in surgery first and the relation between airway/obstructive sleep apnea and orthognathic surgery.
CONCLUSIONS: Bibliometric and altmetric analysis for free using Google Scholar and Dimensions is laborious but possible. Bibliometrics is a powerful tool to become actualized at any health professional level, from students to academics; and could save considerable effort and time for parties interested in the topic. Appropriate keywords are a crucial step to wider article dissemination.

A Bibliometric Analysis of Neurosurgery Research Productivity in Arab Countries between 2005 and 2019.

Hani Chanbour, Jad El Masri, Shadi Bsat, Ayman Bsat, Ahmad Jiblawi, Tarek Sunna.

   BACKGROUND: Arab World is lagging behind in the world of publications and research, especially in the biomedical related field. This is a bibliometric analysis that aims to assess the neurosurgical research productivity across different Arab countries.
METHODS: PubMed was used to quantify the number of neurosurgery-related articles published by each Arab country, by several journals, investigating specific topics, between 2005 and 2019. Numbers were normalized with respect to each country's average population and average Gross Domestic Product.
RESULTS: Arab countries contributed by 0.53% of total neurosurgery publications. Egypt had the highest number of neurosurgery related publications (362), ahead of Saudi Arabia (238) and Lebanon (133). In terms of publications per million persons, Lebanon was first with 21.6 publications per million persons. In terms of GDP, Egypt ranked first with 18.85 publications per million $. There was an insignificant correlation between the number of publications on one hand, and the average GDP (p=0.09) on the other hand. Whereas, average population explains around 50% of the neurosurgery related publications (R squared= 0.49, p<0.01). Neoplasms were the dominating area of research, and "World Neurosurgery" journal had the highest number of publications.
CONCLUSION: The results reached by this study reflect an undoubtable need for more research on neurosurgery by the Arab countries. This goes back to the different obstacles facing Arab countries every day, affecting the economical, educational, and health care system.

   BACKGROUND: Numerous studies related to Helicobacter pylori (H. pylori) eradication have been published since the discovery of H. pylori. This study aimed to use a quantitative method to assess the development of this field.
MATERIALS AND METHODS: We performed a search of related articles from Web of Science published in 1983-2020 using a combination of the search terms "H. pylori" and "eradication". Eligible studies were included after a two-stage screening process, and the following data were extracted: title, author, institution, country, study type, sample size, eradication regimen, publication year, number of citations, journal, and H-index.
RESULTS: A total of 1402 studies were finally identified. The results showed that the period from 1994-2003 was the most influential period in this field. Italy and the USA were dominant countries in this field, while China's publication number increased sharply in the last ten years. Baylor College of Medicine was the most influential institution. Alimentary Pharmacology Therapeutics was the most productive journal. The effects of H. pylori eradication on peptic ulcers and gastric cancer and H. pylori eradication therapy were the most cited topics in this field. After the publish of Maastricht/Florence Ⅳ guideline, the research of quadruple therapy was more than triple therapy. Bismuth-containing quadruple therapy became the most focused regimen after Maastricht/Florence Ⅴ guideline.
CONCLUSIONS: In this study, we summarized the characteristics of the publications; identified the most influential countries, institutions, journals; identified the popular research topics and eradication regimen of clinical H. pylori eradication.

Tosin Yinka Akintunde, Taha Hussein Musa, Hassan Hussein Musa, Shaojun Chen, Elhakim Ibrahim, Sayibu Muhideen, Joseph Kawuki.

  Introduction: The Ebola Virus outbreak in Africa is believed to be one of the deadliest viral infections that causes severe hemorrhagic fever in human and nonhuman primates, which has resulted in increased mortality rates in the affected African countries. Thus, the current study mapped and quantified global research output and trends in the EBOV vaccine publications via a bibliometric analysis.Methods: Publications about the Ebola virus vaccine were extracted from the Web of Science and Scopus databases. HistCite, Bibliometrix, an R package, and VOSviewer.Var1.6.6 were used for data mapping and analysis.Results: A total of 541 (WoS) and 511 (Scopus) documents were included, with a cumulation of 24,611 citations in both databases. These documents were published in 141 journals in the Wos and 185 in Scopus. The USA was the most productive country with 206 (38.08%) publications in the Wos. Although the top-cited authors are from the USA, the United Kingdom, and Canada, only one author from Africa "Samai M" from the University of Sierra Leone contributed 13 publications. Meanwhile, the Journal of Infectious Diseases was the most productive (45, 8.32%) in this field.Conclusion: The study provides insight for researchers and health policy on the trends and progress of the EBOV vaccine research and development, focusing on the hot topics, research collaboration, and research dearth that requires urgent redress to fast-track an all-inclusive EBOV vaccine development.

Randomized Controlled Trials of Mindfulness and Acceptance-Based Interventions Over the Past Two Decades: A Bibliometric Analysis.

Yan Ma, Kristen M Kraemer, Jiaxuan Lyu, Gloria Y Yeh.

  Introduction: The past several years have witnessed a significant increase in interest among the public in mindfulness with an unmistakable growth in the scientific literature investigating mindfulness-based therapies. A myriad of therapeutic uses of mindfulness have been studied. Given this burgeoning interest, the authors' objective was to conduct a broad-sweeping bibliometric analysis over the past two decades to describe overarching trends in the publications of randomized controlled trials (RCTs) investigating mindfulness to broadly identify both strengths and gaps in this field and inform a strategic plan for further advancing this research area. Materials and Methods: The authors retrieved mindfulness-focused RCTs available on PubMed in the past two decades (2000-2019). They synthesized the literature with respect to publication numbers, countries of publication, journal type, areas of research focus, characteristics of study designs, sample size, and trends in remote intervention delivery. Results: The resulting 1389 publications represent a near exponential growth trend over the past 20 years. Publications from the top three countries (the United States, the United Kingdom, and the Netherlands) with the highest productivity accounted for 60% of total number of publications. The most published modalities include acceptance-based therapy (n = 260), mindfulness-based stress reduction (n = 238), mindfulness-based cognitive therapy (n = 174), and dialectical behavior therapy (n = 82). Stress, depression, anxiety, pain, cancer, diet/healthy eating, and sleep were the most common major areas of focus. Studies included active (46%) or inactive controls (44%), and increasingly more studies with both types of controls (10%). The top 10 journals that published the most mindfulness RCTs were from behavioral sciences and psychiatry or psychology. There were 187 RCTs utilizing remote delivery, with 146 (87.1%) in the most recent 5 years. Conclusion: Publications of mindfulness-focused RCTs show a continuous increasing trend. Mindfulness research from non-Western countries and studies published in biomedical journals were less prevalent and potentially represent future opportunities. Trends of studies with both inactive and active controls support an overall advancement in research methodology. There has been a significant expansion of studies of remotely delivered mindfulness interventions. Future research might consider evaluation of a broader range of modalities and further examine optimal delivery formats.

Gender Disparities in Cardiology-Related COVID-19 Publications.

Elena C Vasti, David Ouyang, Summer Ngo, Ashish Sarraju, Robert A Harrington, Fatima Rodriguez.

   INTRODUCTION: Female authors are underrepresented in cardiology journals, although prior work suggested improvement in reducing disparities over time. Early in the recent COVID-19 pandemic, female authorship continued to lag that of their male counterparts despite a surge in publications. The cumulative impact of the COVID-19 pandemic on authorship gender disparities remains unclear. We aimed to characterize gender disparities in COVID-19-related cardiology publications across the duration of the ongoing pandemic.
METHODS: We retrospectively analyzed COVID-19-related research articles published in the top 20 impact factor cardiology journals between March and June 2021. Gender representation data were extracted for any author, first authors, and senior authors.
RESULTS: We found that 841 articles were related to COVID-19, with a total of 5586 authors and an average of 42 articles per journal. Less than a third (29.9%) of the total authors from publications were women. Women represented a smaller proportion of first authors (21.3%) and senior authors (16.4%).
CONCLUSIONS: Female authorship has continued to lag male authorship for the duration of the ongoing COVID-19 pandemic. The pandemic may have impeded progress in reducing gender disparities in academic cardiology publications. The low proportions of first and senior female authors may reflect the impact of the pandemic on women in cardiology in leadership domains.

Correlation between Twitter mentions and academic citations in sexual medicine journals.

Mehmet Serkan Ozkent, Kadir Böcü, Emre Altintas, Murat Gul.

Social media services, especially Twitter, are used as a commonly sharing tool in the scientific world. This widespread use of Twitter would be an effective method in spreading academic publications. So, we aimed to investigate the relationship between Twitter mentions and traditional citations of articles in sexual medicine journals in this study. We reviewed the articles published in seven journals of sexual medicine (2 years after the publication of the articles) between January 2018 and June 2018. In the first half of 2018, 410 articles were extracted. Of these, 352 (85.9%) were original articles, while 58 (14.1%) were review articles. The median number of citations of the articles mentioned at least once on Twitter was 7 (interquartile range: 0-111) for Google Scholar, whereas it was 0 (interquartile range: 0-63) for Scopus, respectively. It was 4 (interquartile range: 0-25) for Google Scholar and 0 (interquartile range: 0-7) for Scopus. The publications mentioned on Twitter were cited more than the non-mentioned publications in the traditional-based citation system (p < 0.001). A significant relationship between the citation numbers and tweet numbers was also observed (p < 0.001). Also, in the linear regression model, the tweet numbers (p < 0.001) and article types (p < 0.001) were found to be related to the Google Scholar citation numbers. In conclusion, using Twitter as a professional tool in academic life would allow information to be propagated and responded quickly, especially for sexual medicine journals.

Yansong Bao, Khalid Mehmood, Saifullah, Muhammad Yaseen, Saad Dahlawi, Muhammad Mohsin Abrar, Muhammad Ajmal Khan, Shah Saud, Khadim Dawar, Shah Fahad, Turki Kh Faraj.

  Electric vehicles (EVs) can substantially decrease atmospheric pollutant emissions, thereby improving air quality, decreasing global warming, and improving human health. In this study, we performed a comprehensive bibliometric analysis using Web of Science to understand the research developments and future perspectives in EVs between 1974 and 2021. The analysis of indicators such as research trends, publication growth, and keywords revealed that most research in the selected timeframe was focused on applying and optimizing the existing technologies of different types of EVs to decrease air pollution and mortality. The changes in air quality owing to such electrification received special attention, with approximately 441 publications preferably in the English language. Among all the retrieved documents, research articles were most common (n = 295; 66.89% of the global output), dominated by the research domains of environmental sciences, followed by energy fuels and transportation science technology. Journal analysis revealed that Sustainability (n = 19, 4.30%) was the leading journal, followed by Journal of Cleaner Production and Science of the Total Environment. The most frequently used keywords were "electric vehicles," "air quality," and "air pollution." The most highly impactful article was published by Jacobson et al. (2005) in Science, with 620 total citations and 38.82 average annual citations. Furthermore, the United States (n = 118; 26.75% of the global output) had the highest publication rate, followed by China and the United Kingdom. The leading institutions were Tsinghua University (n = 16; 3.62% of the global research output) in China, followed by the University of Michigan and Cornell University in the United States. The current analysis warrants more focus on comprehensive analysis employing transport and chemistry modeling and using the latest technology for long life and sustainable batteries. This study provides a basis for future studies on improving air quality through innovative work in the electrification of vehicles.

Detecting anomalous citation groups in journal networks.

Sadamori Kojaku, Giacomo Livan, Naoki Masuda.

The ever-increasing competitiveness in the academic publishing market incentivizes journal editors to pursue higher impact factors. This translates into journals becoming more selective, and, ultimately, into higher publication standards. However, the fixation on higher impact factors leads some journals to artificially boost impact factors through the coordinated effort of a "citation cartel" of journals. "Citation cartel" behavior has become increasingly common in recent years, with several instances being reported. Here, we propose an algorithm-named CIDRE-to detect anomalous groups of journals that exchange citations at excessively high rates when compared against a null model that accounts for scientific communities and journal size. CIDRE detects more than half of the journals suspended from Journal Citation Reports due to anomalous citation behavior in the year of suspension or in advance. Furthermore, CIDRE detects many new anomalous groups, where the impact factors of the member journals are lifted substantially higher by the citations from other member journals. We describe a number of such examples in detail and discuss the implications of our findings with regard to the current academic climate.

Mahdi Malakoutikhah, Moslem Alimohammadlou, Hadiseh Rabiei, Seyed Aliakbar Faghihi, Mojtaba Kamalinia, Mehdi Jahangiri.

  Purpose: This scientometric study was aimed to investigate research and hot topics on unsafe behavior.Methods and Materials: This study was performed using Scientometric analysis mapping tools, such as CiteSpace, Gephi, MINITAB, and VOSviewer for statistical analysis. Studies published in Web of Sciences were included in our study.Results: The first study was published in 1987. The results of the study showed that the Safety Science journal with 111 studies (10.45%), presented most of published studies in this field. United States and China were the two producing countries, with 289 and 229 published studies, respectively. The results of keywords and hot topics showed that between 1991-2000, Safety climate, Safety performance and Modelling were ranked first to third most frequent words, and during 2001-2010, Safety performance was removed from the list of top ten keywords, while Safety climate and Modelling were ranked respectively ninth and sixth most frequent words. Finally, between 2011-2020, keyword Organizational factors has risen to the first rank, indicating the significance of this keyword in the futures.Conclusions: According to the results of the present study, it can be concluded that future studies on unsafe behavior can be conducted in the field of organizational factors.

Aquatic Exercise for Health Promotion: A 31-Year Bibliometric Analysis.

Wen-Sheng Zhou, Fei-Fei Ren, Yong Yang, Kuei-Yu Chien.

  The present study aimed to review the research literature on aquatic exercise for health promotion using bibliometric methods and CiteSpace software. The number of studies related to this topic are constantly expanding, with the USA, Brazil, and Australia the centers of this research. Most published papers fall within Sports Science, but the disciplines of Physiology, Psychology, and Rehabilitation were also found to be dominant domains for this literature. The seven most prolific authors were from Brazil or Spain. The most frequently cited references focused on sub-topics of physiology, biochemistry, physical fitness, psychological health, cardiovascular disease, and joint disease. New research trends have shifted to the promotion of cardiovascular health in clinical populations (stroke, overweight, hypertension, endothelium dysfunctional, obese, inflammation, antioxidant, heart failure). Overall, this review found that research hot spots and trends in this realm have focused on improving cardiovascular health with aquatic exercise.

Scientometric analysis of the Chaos journal (1991-2019): From descriptive statistics to complex networks viewpoints.

Stéphanie Depickère, Jürgen Kurths, Gonzalo Marcelo Ramírez-Ávila.

We performed a scientometric analysis of Chaos papers from 1991 to 2019, applying a careful disambiguation process for identifying the authors correctly. First, we used standard scientometric tools based on descriptive statistics. This analysis enabled us to compute productivity and the degree of collaboration. The evolution in the number of authors, countries, and topics per article has an increasing trend. An analysis of the citations considering their temporal mean number exhibits a growing tendency in time. Second, we dealt with Lotka-Zipf's law considering the rank distributions of 15 datasets. We found that the sum of Crossref citations by country was the only dataset for which the power-law was the only plausible distribution. Next, we examined the networks of authors, countries, and topics, going from the simplest case of undirected and unweighted networks to the general case of weighted and directed networks and assigning a weight to the individual nodes. Based on the networks' topology and features, we introduced diversity, collaboration, influence, and productivity measures and found a significant increase in the diversity of all the considered networks (authors, countries, and topics) but manifesting a very different network structure. The computation of typical network quantities combined with the communities' identification reveals the presence of several hubs and the existence of various communities that encompass nodes of all the continents in the case of countries. Finally, using the most general networks, it was possible to compute influence and productivity indexes to find the USA, China, and Germany's leadership inside the network.

Gender disparity between authors in leading medical journals during the COVID-19 pandemic: a cross-sectional review.

Vaidehi Misra, Frozan Safi, Kathryn A Brewerton, Wei Wu, Robin Mason, An-Wen Chan, Paula A Rochon, Iliana C Lega, Husam Abdel-Qadir.

   OBJECTIVES: Evaluate gender differences in authorship of COVID-19 articles in high-impact medical journals compared with other topics.
DESIGN: Cross-sectional review.
DATA SOURCES: Medline database.
ELIGIBILITY CRITERIA: Articles published from 1 January to 31 December 2020 in the seven leading general medical journals by impact factor. Article types included primary research, reviews, editorials and commentaries.
DATA EXTRACTION: Key data elements were whether the study topic was related to COVID-19 and names of the principal and the senior authors. A hierarchical approach was used to determine the likely gender of authors. Logistic regression assessed the association of study characteristics, including COVID-19 status, with authors' likely gender; this was quantified using adjusted ORs (aORs).
RESULTS: We included 2252 articles, of which 748 (33.2%) were COVID-19-related and 1504 (66.8%) covered other topics. A likely gender was determined for 2138 (94.9%) principal authors and 1890 (83.9%) senior authors. Men were significantly more likely to be both principal (1364 men; 63.8%) and senior (1332 men; 70.5%) authors. COVID-19-related articles were not associated with the odds of men being principal (aOR 0.99; 95% CI 0.81 to 1.21; p=0.89) or senior authors (aOR 0.96; 95% CI 0.78 to 1.19; p=0.71) relative to other topics. Articles with men as senior authors were more likely to have men as principal authors (aOR 1.49; 95% CI 1.21 to 1.83; p<0.001). Men were more likely to author articles reporting original research and those with corresponding authors based outside the USA and Europe.
CONCLUSIONS: Women were substantially under-represented as authors among articles in leading medical journals; this was not significantly different for COVID-19-related articles. Study limitations include potential for misclassification bias due to the name-based analysis. Results suggest that barriers to women's authorship in high-impact journals during COVID-19 are not significantly larger than barriers that preceded the pandemic and that are likely to continue beyond it.

Evaluation of the academic achievements of clinician health services research scientists involved in "pre-K" career development award programs.

Erin F Barreto, Rozalina G McCoy, Joseph J Larson, Rahma M Warsame, Cassie C Kennedy, Ashley E Baker, Elizabeth S Hart, Stephanie M Pagel, Samantha A Whitman, Kasey R Boehmer, Felicity T Enders.

   Introduction: Research career development awards (CDAs) facilitate development of clinician-scientists. This study compared the academic achievements of individuals in a structured institutional "pre-K" CDA program, the Mayo Clinic Kern Scholars program, with individuals who applied for but were not admitted to the Kern program ("Kern applicants"), and awardees of other unstructured internal CDAs.
Methods: This was a longitudinal cohort study of clinicians engaged in research at Mayo Clinic between 2010 and 2019. The primary outcome was time to the 15th new peer-reviewed publication after the program start, adjusted for baseline number of publications. Secondarily, we described successful awarding of federal funding by the NIH or VA.
Results: The median (IQR) number of baseline publications was highest among Kern Scholars compared to Kern Applicants or other CDA awardees [16 (12, 29) vs 5 (1, 11) and 8 (5, 16); P < 0.001]. After adjustment for baseline publications, the time to 15th new publication was significantly shorter for Kern Scholars than for the two comparator groups (P<0.001). Similar findings were observed with total new publications within 5 years (P < 0.001), as well as number of new first-/last-author publications within 5 years (P < 0.001). The overall frequency of K-awards, R-awards (or equivalent), or any funding were similar between groups, with the exception of R03 awards, which were significantly more common among Kern Scholars (P = 0.002).
Conclusion: The Kern Scholars program is a successful training model for clinician-scientists that demonstrated comparatively greater acceleration of scholarly productivity than other internal CDA programs.

Understanding the Diffusion of Theoretical Knowledge in Nursing: A Citation Analysis of Meleis's Transition Theory.

Kemal Yayla.

   Aim: The aim of this study is to examine the structure of the knowledge creation process in nursing science and to investigate the dissemination of theoretical knowledge in other disciplines by analyzing citations and social network data.
Method: This exploratory study evaluated Metadata to find academic publications. Meleis's Transition Theory was selected as a case study. A majority of the publications that represented the transition theory were assigned as the core of the theory. Forward and backward citations were used as agents of knowledge linkage to determine the dissemination of the theory in the field of science. Social network analysis and visualization were used to depict graphical and structural relations of the research front and the knowledge base.
Results: The knowledge base of the Transition Theory was built on 7 different information networks. The most effective and vast information network consisted of Meleis, AI as a researcher and the central information network, which is the journal of Nursing Research. Oncology, geriatrics, public health, and psychology in the areas of information propagation within the field of nursing were considered as research areas where the theoretical framework provided by the theory was rendered functional.
Conclusion: In recent years, the use of theoretical frameworks has become a necessity to assess the changing needs of the study of nursing science. The method used in the study can be effectively used to analyze the conceptual structures in the nursing education and professional application processes and to understand the origins of these theories. Further research can help to structure the use of informational science-based research designs to understand the connections between theory, clinical practice, and the development of educational contents in nursing faculties.

Application of real options in carbon capture and storage literature: Valuation techniques and research hotspots.

Casper Boongaling Agaton.

  Carbon capture and storage (CCS) is one of the key technologies and measures for the energy transition towards achieving the climate targets. Accounting for the high uncertainty, risks, and irreversibility of CCS projects, a growing number of studies apply the real options (RO) approaches which allow flexibility in the valuation of uncertain investment. Various RO models and valuation techniques are adopted and the critical analysis of the research trends and research hotspots in RO designs in CCS investments has not been made yet. This study employs a bibliometric analysis to examine the features of CCS literature including the research focus and trends as well RO uncertainty and models, types of options, and valuation techniques. The results present a comprehensive overview of the state-of-the-art which provides researchers a concrete basis for future research and directions for further development. This further provides energy and environmental policymakers and CCS project planners with valuable insights on various aspects of CCS policy and project design.

Media Multitasking: A Bibliometric Approach and Literature Review.

Emma Beuckels, Guoquan Ye, Liselot Hudders, Veroline Cauberghe.

  Media multitasking became increasingly popular over the past decade. As this behavior is intensely taxing cognitive resources, it has raised interest and concerns among academics in a variety of fields. Consequently, in recent years, research on how, when, and why people media multitask has strongly emerged, and the consequences of the behavior for a great variety of outcomes (such as working memory, task performance, or socioemotional outcomes) have been explored. While efforts are made to summarize the findings of media multitasking research until date, these meta, and literature studies focused on specific research subdomains. Therefore, the current study adopted a quantitative method to map all studies in the broad field of media multitasking research. The bibliometric and thematic content analyses helped us identifying five major research topics and trends in the overall media multitasking domain. While media multitasking research started by studying its prevalence, appearance, and predictors, early research within the domain was also interested in the impact of this media consumption behavior on individuals' cognitive control and academic performance. Later on in 2007, scholars investigated the implications of media multitasking on the processing of media- and persuasive content, while its impact on socioemotional well-being received attention ever since 2009. Our analyses indicate that research within the field of media multitasking knows a dominant focus on adolescents, television watching, and cognitive depletion. Based on these findings, the paper concludes by discussing directions for future research.

Reporting ethical approval in health and social science articles: an audit of adherence to GDPR and national legislation.

Kjell Asplund, Kerstin Hulter Åsberg.

   BACKGROUND: Previous studies have indicated that failure to report ethical approval is common in health science articles. In social sciences, the occurrence is unknown. The Swedish Ethics Review Act requests that sensitive personal data, in accordance with the EU General Data Protection Regulation (GDPR), should undergo independent ethical review, irrespective of academic discipline. We have explored the adherence to this regulation.
METHODS: Using the Web of Science databases, we reviewed 600 consecutive articles from three domains (health sciences with and without somatic focus and social sciences) based on identifiable personal data published in 2020.
RESULTS: Information on ethical review was lacking in 12 of 200 health science articles with somatic focus (6%), 21 of 200 health science articles with non-somatic focus (11%), and in 54 of 200 social science articles (27%; p < 0.001 vs. both groups of health science articles). Failure to report on ethical approval was more common in (a) observational than in interventional studies (p < 0.01), (b) articles with only 1-2 authors (p < 0.001) and (c) health science articles from universities without a medical school (p < 0.001). There was no significant association between journal impact factor and failure to report ethical approval.
CONCLUSIONS: We conclude that reporting of research ethics approval is reasonably good, but not strict, in health science articles. Failure to report ethical approval is about three times more frequent in social sciences compared to health sciences. Improved adherence seems needed particularly in observational studies, in articles with few authors and in social science research.

Preparing Teachers to Teach in K-12 Blended Environments: A Systematic Mapping Review of Research Trends, Impact, and Themes.

Cecil R Short, Charles R Graham, Theresa Holmes, Laura Oviatt, Hannah Bateman.

  Despite evidence concerning the widespread growth of K-12 blended teaching and the impact that emergency remote teaching during the COVID-19 pandemic has had on the spread of K-12 online and blended teaching, we could find no systematic reviews focused on preparing K-12 teachers for blended teaching. Previous literature reviews, such as those from Halverson et al. (2012) and Drysdale et al. (2013), have noted the lack of research focused on K-12 blended teaching contexts. This systematic mapping review (Grant & Booth, 2009) of 88 K-12 blended teacher preparation articles focused on identifying trends in author impact according to citation count and number of publications, journal impact according to number of publications, prevalence of research methods, and prevalence of research themes according to research questions and findings. The analysis provides a valuable snapshot of current literature, sets a foundation for a deeper thematic analysis of K-12 blended teacher preparation literature, and identifies some potential areas for future K-12 blended teaching research.

[Cognitive Reserves: Prefrontal Cortex or Information Load?]

M A Bakaev, O M Razumnikova.

Information technology is becoming an increasingly important tool of scientific knowledge due to the exponential growth of the number of publications presenting the results of neurobiological and psychological research. To identify predictors of cognitive reserves and methods for their determination based on the developed applied ontology, we performed a bibliometric analysis of publications contained in the PubMed database. It is shown that the annual growth in the number of publications relevant to the topic in the period 1990-2019 was 11%, which is higher than the average for science. We found the following psychophysiological indicators of cognitive reserves to gain the greatest increase in the interest of researchers: prefrontal cortex, beta range (13-30 Hz) of EEG, inhibition and information load. Analysis of the role of these factors suggests that the development and/or realization of cognitive reserves is provided due to inhibitory functions of the prefrontal cortex for the effective selection of relevant stimuli under conditions of information load. The identified predictors of cognitive reserves and the most popular methods of their psychometric assessment can be useful for choosing new areas of research in gerontology.

The Repository for Caribbean Cancer Publications (ReCCaP): Database Development and Publication Trends 2004-2019.

Kimberly Badal, Moesha Moore, Mikhail Thomas.

   Objective: In the Caribbean region, research has been limited, making it challenging to find. In order for the region to optimally access and utilize present research and identify gaps, we developed the Repository for Caribbean Cancer Publications (ReCCaP) to home publications on cancer in the Caribbean population and diaspora and report on publication trends.
Methods: A systematic PubMed literature search for the period 2004-2019 (15 years) was developed using keywords related to "cancer" and "Caribbean." Three independent investigators verified included publications. The final database was formatted and hosted in an online database management software. Publication trends over time, by country, cancer type, and income classification were investigated.
Results: Of the 4935 publications found, 1194 papers met the inclusion criteria with 803 publications (67.25%) being on the Caribbean population, 139 publications (11.64%) including multiple Caribbean countries and 252 publications (21.11%) on the diaspora. Between 2004 and 2019, there was an overall 0.20 increase in publications regionally. Overall, most publications were on breast (n = 168, 14.07%), prostate (n = 156, 13.07%), cervical (n = 152, 12.73%), colorectal (n = 80, 6.70%), and lung cancer (n = 36, 3.02%). The highest number of papers were published by Puerto Rico (22.80 pubs/year), Cuba (8.27 pubs/year), Jamaica (6.27 pubs/year), Trinidad and Tobago (3.53 pubs/year), and Martinique (2.27 pubs/year). The high-income countries (n=10) collectively lead in publications over the 15-year period.
Conclusion: ReCCaP provides an easily searchable database highlighting published work and gaps in knowledge on cancer in the Caribbean and diaspora.

An Evaluation of Racial Diversity in Craniofacial Surgery Literature.

Danielle L Sobol, Daniel Y Cho, Jonathan P Massie, Jacob R Burns, Christopher S Crowe, Cameron J Kneib, Megan Lane, Afaaf Shakir, Shane D Morrison, Russell E Ettinger.

ABSTRACT: Implicit bias can lead to discrimination of certain populations within healthcare. Representation in medical literature is no exception and it is hypothesized that images with lighter skin tone are more prevalent than darker skin tones in craniofacial literature. Clinical photographs and figure graphics from 5 journals were examined for pre-defined years. Annals of Plastic Surgery, Aesthetic Surgery Journal, Journal of Craniofacial Surgery, Journal of Plastic, Reconstructive and Aesthetic Surgery, and Plastic and Reconstructive Surgery journals were reviewed. All craniofacial-focused articles containing at least one color image depicting human skin were included. 10,477 images and 627 graphics were evaluated using the Fitzpatrick scale as a guide. Most journals trended toward broader inclusion of nonwhite photographs and graphics over time. In 2016, 47% of articles published in Journal of Craniofacial Surgery included nonwhite images compared to Annals of Plastic Surgery (16%), Aesthetic Surgery Journal (40%), Journal of Plastic, Reconstructive and Aesthetic Surgery (25%), and Plastic and Reconstructive Surgery (7%). Comparison of domestic and international publications demonstrated that author's country of origin impacted the percentage of nonwhite clinical photographs for most journals. Comparisons of publications by country demonstrated increased diversity in Asia and the Middle East for clinical photographs but not graphics. The frequency of nonwhite figure graphics was staggeringly low, identified in only 18 articles across all journals and years. Craniofacial literature more commonly reflects white skin tones. The trend over time suggests increasing inclusion of racial diversity in clinical photographs; however, figure graphics remain less racially diverse. Time, country of origin, and publishing journal appear to play a role.

Review of flipped learning in engineering education: Scientific mapping and research horizon.

Md Abdullah Al Mamun, Md Abul Kalam Azad, Md Abdullah Al Mamun, Michael Boyle.

  The COVID-19 pandemic makes flipped learning more relevant to address the challenges of remote learning. Therefore, renewed attention is warranted in critically appraising the implications on which flipped learning is built. Though several studies have reviewed the flipped learning research in the past, the majority has qualitatively synthesized the flipped learning literature, thus, lacking the overall perspective provided quantitatively for appraising the existing state of affairs of flipped learning research in engineering education. This study addresses this gap by objectively mapping the conceptual, intellectual, and social structure of research development in flipped learning using a bibliometric review method. Findings reveal that flipped learning in engineering education is a relatively new field of research and in recent time it has entered into the stage of exponential growth. Findings also show the effectiveness of the flipped learning model to address the challenges of complex pedagogical applications in different fields of engineering education. This study provides a quantitative synopsis of the flipped learning literature which can be used as an anchor for future study.

   INTRODUCTION: This paper presented qualitative and quantitative data collected on the research capacity of global health institutions in China and aimed to provide a landscaping review of the development of global health as a new discipline in the largest emerging economy of the world.
METHODS: Mixed methods were used and they included a bibliometric analysis, a standardised survey and indepth interviews with top officials of 11 selected global health research and educational institutions in mainland China.
RESULTS: The bibliometric analysis revealed that each institution had its own focus areas, some with a balanced focus among chronic illness, infectious disease and health systems, while others only focused on one of these areas. Interviews of key staff from each institution showed common themes: recognition that the current research capacity in global health is relatively weak, optimism towards the future, as well as an emphasis on mutual beneficial networking with other countries. Specific obstacles raised and the solutions applied by each institution were listed and discussed.
CONCLUSION: Global health institutions in China are going through a transition from learning and following established protocols to taking a more leading role in setting up China's own footprint in this area. Gaps still remain, both in comparison with international institutions, as well as between the leading Chinese institutions and those that have just started. More investment needs to be made, from both public and private domains, to improve the overall capacity as well as the mutual learning and communication within the academic community in China.

PhD-trained scientists are essential contributors to the workforce in diverse employment sectors that include academia, industry, government, and nonprofit organizations. Hence, best practices for training the future biomedical workforce are of national concern. Complementing coursework and laboratory research training, many institutions now offer professional training that enables career exploration and develops a broad set of skills critical to various career paths. The National Institutes of Health (NIH) funded academic institutions to design innovative programming to enable this professional development through a mechanism known as Broadening Experiences in Scientific Training (BEST). Programming at the NIH BEST awardee institutions included career panels, skill-building workshops, job search workshops, site visits, and internships. Because doctoral training is lengthy and requires focused attention on dissertation research, an initial concern was that students participating in additional complementary training activities might exhibit an increased time to degree or diminished research productivity. Metrics were analyzed from 10 NIH BEST awardee institutions to address this concern, using time to degree and publication records as measures of efficiency and productivity. Comparing doctoral students who participated to those who did not, results revealed that across these diverse academic institutions, there were no differences in time to degree or manuscript output. Our findings support the policy that doctoral students should participate in career and professional development opportunities that are intended to prepare them for a variety of diverse and important careers in the workforce.
