       OBJECTIVE: This study aimed to analyze the progression and trends of multimorbidity in the elderly in China and internationally from a bibliometric perspective, and compare their differences on hotspots and research fronts.
    METHODS: Publications between January 2001 and August 2021 were retrieved from WOS and CNKI databases. Endnote 20 and VOSviewer 1.6.8 were used to summarize bibliometric features, including publication years, journals, and keywords, and the co-occurrence map of countries, institutions, and keywords was drawn.
    RESULTS: 3857 research papers in English and 664 research papers in Chinese were included in this study. The development trends of multimorbidity in the elderly are fully synchronized in China and other countries. They were divided into germination period, development period, and prosperity period. Research literature in English was found to be mainly focused on public health, and the IF of the literature is high; In China, however, most research papers are in general medicine and geriatrics with fewer core journals. Co-occurrence analysis based on countries and institutions showed that the most productive areas were the United States, Canada, the United Kingdom, and Australia, while the Chinese researchers have made little contribution. The clustering analysis of high-frequency keywords in China and around the globe shows that the hotspots have shifted from individual multimorbidity to group multimorbidity management. Sorting out the top 10 highly cited articles and highly cited authors, Barnett, K's article published in Lancet in 2012 is regarded as a milestone in the field.
    CONCLUSION: Multimorbidity in the elderly leads to more attention in the world. Although China lags behind global research the research fronts from disease-centered to patient-centered, and individual management to population management is consistent.

      Research on cybercrime victimization is relatively diversified; however, no bibliometric study has been found to introduce the panorama of this subject. The current study aims to address this research gap by performing a bibliometric analysis of 387 Social Science Citation Index articles relevant to cybercrime victimization from Web of Science database during the period of 2010-2020. The purpose of the article is to examine the research trend and distribution of publications by five main fields, including time, productive authors, prominent sources, active institutions, and leading countries/regions. Furthermore, this study aims to determine the global collaborations and current gaps in research of cybercrime victimization. Findings indicated the decidedly upward trend of publications in the given period. The USA and its authors and institutions were likely to connect widely and took a crucial position in research of cybercrime victimization. Cyberbullying was identified as the most concerned issue over the years and cyber interpersonal crimes had the large number of research comparing to cyber-dependent crimes. Future research is suggested to concern more about sample of the elder and collect data in different countries which are not only European countries or the USA. Cross-nation research in less popular continents in research map was recommended to be conducted more. This paper contributed an overview of scholarly status of cybercrime victimization through statistical evidence and visual findings; assisted researchers to optimize their own research direction; and supported authors and institutions to build strategies for research collaboration.

       BACKGROUND: In recent years, the issue of postoperative pain has raised wide concern in the medical community. Postoperative hyperalgesia (POH), as the primary etiology of pain, has been extensively studied and numerous articles have been published on this topic; however, no comprehensive bibliometric review of POH publications has been conducted. Thus, we aimed to examine the 100 top-cited reports on POH and summarize their key characteristics.
    METHODS: Published studies on POH were retrieved from the Web of Science Core Collection (WoSCC) using the search terms "postoperative hyperalgesia". All papers published since 1980 were searched. The search results were sorted by the frequency of the total citations, and 2 reviewers independently skimmed the abstracts and full texts to identify the 100 top-cited reports. After the 100 top-cited papers were identified, the following data were extracted by the two reviewers: the title, surname(s) of the author(s), name of the first author, publication year, country of origin, article type, institutional affiliations, keywords, source journal, and impact factor (IF) of the journal.
    RESULTS: The initial search returned 1,747 papers, published in 466 journals that originated from 1,679 institutions in 48 countries. The 100 top-cited reports received 21,454 citations. The USA was the most cited and most productive country, contributing nearly half of the 100 top-cited papers. The numbers of studies on POH have trended upward and continue to increase each year.
    CONCLUSIONS: An analysis of the 100 top-cited studies on POH provided a better guidance for ongoing researches. The prominent keywords "opioid-induced hyperalgesia", especially "remifentanil", is still on top of POH research area. Nevertheless, the mechanism of POH is intricate and unclear, which is crucial to conduct further studies and find some new interventions.

      This paper conducted a comprehensive analysis based on bibliometrics and science mapping analysis. First, 848 publications were obtained from Web of Science. Their fundamental characteristics were analyzed, including the types, annual publications, hot research directions, and foci (by theme analysis, co-occurrence analysis, and timeline analysis of author keywords). Next, the prolific objects (at the level of countries/regions, institutions, journals, and authors) and corresponding pivotal cooperative relationship networks were used to highlight who pays attention to FinTech. Furthermore, the citation structures of authors and journals were investigated, including citation and co-citation. Additionally, this paper presents the burst detection analysis of cited authors, journals, and references. Finally, combining the analysis results with the current financial environment, the challenges and future development opportunities are discussed further. Accordingly, a comprehensive study of the FinTech documents not only reviews the current research characteristics and trajectories but also helps scholars find the appropriate research entry point and conduct in-depth research.

       PURPOSE: To determine the institutions, journals of choice and topics of investigation of the most prolific and highly cited Spanish optometrist researchers.
    METHODS: As a primary search strategy, the Scopus database (Elsevier) was queried with the terms (optometr* OR "contact lens*" OR refracti* OR *ocular) and the affiliation country filter "Spain". The list of authors returned by the primary search was used in a secondary manual search based on co-authors and institutions. Authors were included in the analysis if they had an h-index > 10, were of Spanish nationality, were affiliated to Spanish institutions, and possessed an optometry degree. Authors were ranked by h-index, number of publications and number of citations. Topics of research interest and target journals were determined by analyzing the 10 most highly cited papers of each author.
    RESULTS: A total of 32 authors with an h-index > 10 were identified, of whom 14 (43.7%) were female. Only one author had an h-index > 40, and 7 (21.9%) authors had an h-index over 20. The Journal of Cataract and Refractive Surgery was the first journal of choice (19.1% of highest cited papers), followed by Optometry and Vision Science (10.3%). The Universidad Complutense de Madrid hosted the largest percentage of authors (18.7%), followed by the Universitat de València (15.6%). Main topics of research interest were topography (6.5% of papers), cornea (6.2%) and contact lens (5.0%).
    CONCLUSION: Optometry in Spain is a fertile field of research, with an increasing number of highly cited authors publishing in high impact journals.

      The bibliometric analysis was conducted to evaluate the publication characteristics of Journal of Dental Sciences (JDS) from ScienceDirect Online between 2009 and 2020. The most common published article type in JDS was original articles. The top four highest number of published articles were related to oral and maxillofacial surgery, periodontology, endodontology, and oral pathology. The most productive geographic region for articles was Asia. Taiwan ranked in the highest country in terms of successful publication in JDS. The impact factor of JDS ranged from 0.107 in 2009 to 2.080 in 2020. As compared with years between 2009 and 2014, there was a significant increase in impact factor during 2015-2020 (P = 0.026). By this bibliometric analysis, JDS needs to attract more audience outside the Asia to gain the higher international influence.

       BACKGROUND: Citation analysis was applied to identify the influential studies in the specific field. More and more literature related to carpal tunnel syndrome (CTS) have been published in recent years. To our knowledge, no one has performed a citation analysis of CTS. Thus, our study identified the top 50 influential articles pertaining to CTS and conduct an analysis of their characteristics.
    METHODS: The Web of Science database was used to identify all the articles from 1900 to 2020. We obtained the top 50 articles ranked by citation times, and articles were included and excluded based on the relevance to CTS. Also, we collected the information about journal name, level of evidence, source country and institution, and research type for further analysis.
    RESULTS: The top 50 articles were published between 1959 and 2012. The number of citations ranged from 151 to 1083. The citation density was between 3.23 and 40.27 per year. Muscle Nerve published most articles in CTS research, followed by Journal of Bone and Joint Surgery American Volume. The USA was the leading country, and all the top 5 institutions were from the USA. Katz JN with the highest h-index published most articles. Level III was the most common evidence level.
    CONCLUSIONS: We identified the top 50 cited articles related to CTS. These influential articles might provide researchers with a comprehensive list of the major contribution related to CTS research.

       BACKGROUND: Toll-like receptors (TLRs), a family of innate pattern-recognition receptors, have been exploited as a target for antitumor strategy. An increasing number of TLR agonists, serving as immunotherapeutics or vaccine adjuvants, were developed. This study aimed at exploring the status and trend of current researches on TLR agonists through bibliometric analysis.
    METHODS: Original publications on TLR agonists were collected from the Web of Science Core Collection. Data were analyzed in terms of publication outputs, journals, countries, institutions, authors, co-authorship, co-citation, research hotspots, and evolution trends through VOSviewer and CiteSpace.
    RESULTS: A total of 1914 TLR agonists-related articles, published in 612 academic journals between 2000 and 2019, were enrolled in the study. The Journal of Immunology published the most publications, followed by PLoS One and Blood. The USA that is in possession of the largest number of articles and the most extensive cooperators was the most leading country in this field. University of Minnesota ranked the first in terms of paper totality, but its average citations ranking was lower than University of Pennsylvania. Gudkov AV was the most productive author, whose team reported a TLR5 agonist that had radioprotective activity in mouse and primate models in 2008. The paper of Akira Shizuo, professor of Osaka University, was widely cited by international peers. The research trend of TLR agonists has undergone 3 periods: mechanisms of TLR signalings in immunotherapy (2000-2010), discovery of TLR agonists (2011-2014), application, therapeutic evaluation, and drug design of TLR agonists (2015-2019).
    CONCLUSION: This study provides investigators a landscape of TLR agonists research from the perspective of bibliometrics.

       OBJECTIVE: To investigate the trend of scientific production in relation to the modalities of CAM adopted for the treatment of common mental disorders (CMD), and the evolution and distribution of relevant articles.
    MATERIAL AND METHODS: A bibliometric analysis of studies published between 2001 and 2020 was performed, extracted from the Scopus database, using the terms: integrative medicine, complementary therapy, common mental disorders, anxiety and depression, and synonyms. The relationship between the number of publications, and the years studied were analyzed using Pearson's correlation, followed by linear regression to estimate the number of articles along with the year. The VOSviewer software was used to analyze scientometric data. The study looked at countries with the highest number of publications and citations, co-authorships, most frequent keywords, and leading research organizations.
    RESULTS: In the analysis of the two decades, we identified a high positive correlation between the number of publications and year (r = 0.945). In trend analysis, the linear regression equation predicted the growth of publications along with the year, with R2 = 0.8949 explaining most of the data variability. Spirituality was the most frequent term among the modalities. The concentration of publications and the number of citations were significantly higher in developed countries.
    CONCLUSION: The rise in the number of publications in the past two decades on the application of CAM among individuals with CMD suggests a growing scientific interest in Integrative practices. These bibliometric indicators suggest that new studies are warranted, as well as improvements in public health policies.

       BACKGROUND: Biomarkers have played an important role in the treatment and management of patients with congenital heart disease (CHD). The 100 most frequently cited articles addressing the possible role of biomarkers assessment in treatment and outcomes in patients with CHD were reviewed.
    METHODS: The Web of Science Core Collection database was selected as the database for this selection of publications. CiteSpace 5.7.R1 and VOSviewer 1.6.9 were used to analyze the information.
    RESULTS: A total of 877 articles referencing cardiac biomarkers and CHD were identified in the search period January 1980-June 2020. After screening, the top 100 most cited articles were finally determined. These articles were published in 56 journals, of which the Pediatric Cardiology published the most articles (n=8). Countries collaboration involved a total of 10 countries, and the visualized map indicated the USA had the strongest collaboration network. Related topics of future research will still focus on prevention, general condition evaluation, surgical prognosis evaluation, and application of natriuretic peptide in CHD.
    CONCLUSIONS: We conducted an insight to acquainting characteristics of highly cited publications of biomarkers in CHD and highlighting the research subjects, global research trends, and network collaboration between countries. Related topics of frontiers will focus on: (I) the application of natriuretic peptide, (II) the diagnostic and prognostic value of genes and their related transcriptional translation agents, (III) the use of biomarkers to evaluate and predict the postoperative injury caused by extracorporeal circulation, (IV) and the application of other biomarkers (such as oxidative stress, homocysteine, and thrombosis) to assess and predict damage circumstance.

      Psychedelics were used in the treatment of psychiatric conditions prior to their prohibition in the late 1960s. In the past three decades, there is a revived research interest in the therapeutic potential of psychedelic drugs with expected FDA approvals for treatment of various conditions. Given the exponential scientific growth of this field, we sought to characterize, analyze, and visualize trends in its top-cited articles. Bibliometric analyses are quantitative approaches to characterize a scientific field, including evaluation of the impact of academic literature. The bibliometric analysis and visualizations were conducted with R-tools for comprehensive science mapping. The top-cited 100 articles were cited between 82 and 668 times (median 125; mean 158). Fifty-four percent of the T100 articles were produced in the past decade (2010-2020). Network and author impact analysis highlighted key figures and primary collaboration networks within the top 100 publications. UK, USA, Switzerland, Spain, and Brazil lead the field. Results are discussed in terms of research growth, access, diversity, and the distribution of knowledge and experience in the field. These aggregated data and insights on the second wave of psychedelic research facilitate research evaluation, data-driven funding policies, and a practical map for researchers and clinicians entering the field.

      With the development of new technologies, some concepts become relevant in the economic area, as is the case with cryptocurrencies, in general, or Bitcoin and Ethereum, in particular. Due to the impact of these tools, a detailed bibliometric study that allows us to obtain all information about cryptocurrencies must be conducted. This study will help scientific production by specifying the development and lines of related research that have been followed and are currently being followed. We have used Tableau, R (Bibliometrix R Package), and VOSviewer software to analyze the information. These have been combined to create and review unified metadata from the Web of Science (WoS) and Scopus databases. The bibliometric analysis shows 771 articles on the WoS database and 648 articles on Scopus published between 2010 and early 2019. They present the most relevant articles, research areas, countries, institutions, authors, journals, and trends during the last few years. In conclusion, the number of publications has grown in the last 3 years. The analysis shows the evolution of blockchain technology used in this type of cryptocurrency. The review of this period marks a possible end to the historical part of cryptocurrencies, thereby opening the current topic to its multiple applications.

       BACKGROUND: The world is witnessing new public health crises due to the emergence of the novel coronavirus. This study aims to present a bibliometric analysis of research on coronavirus-related physical/social distancing.
    DESIGN AND METHODS: In this study, a bibliometric analysis was applied to see the research productivity and its impact on coronavirus-related physical/social distancing. For this purpose, Scopus was used to retrieve the data for the analysis. A total of 2900 records was downloaded from the database for analysis.
    RESULTS: The findings revealed that the top four authors published their research in the year 2020. The study ranked the British Medical Journal (BMJ) at the top position on publishing the research on the topic. Similarly, the USA took the lead in all countries in producing research on the topic. The researchers preferred the document type 'Article' for sharing their research, and a single authorship pattern was dominated on all other patterns.
    CONCLUSION: Plenty of bibliometric studies are available on coronavirus, but not a single study is found on coronavirus-related physical/social distancing. This study will be valuable in identifying different bibliometric dimensions on the topic.

      Objective: Diagnostic tools in emergency medicine have been widely studied. As a non-invasive and quick tool, ultrasound plays a role in the field of emergency medicine. Thus, it is significant to understand the global scientific output of this topic. An analysis of publications on the use of ultrasound in emergency medicine over the past decade was performed and summarized to track the current hotspots and highlight future directions. Methods: Globally relevant publications on ultrasound in emergency medicine from 2009 to 2020 were extracted from the Web of Science collection database. VOSviewer software and CiteSpace were employed to visualize and predict the trends in the research on the topic. Results: The overall volume of global publications is on the rise; furthermore, the United States published the most publications in this field and had the most citations and H-index. University of California at San Francisco in the United States has most publications in terms of institutions. The American Journal of Emergency Medicine published the most papers related to ultrasound in emergency medicine in terms of journals. Pulmonary embolism was once the main research direction, and importantly, "point-of-care ultrasound" was determined to be a new research hotspot. Conclusion: Altogether, the number of publications on ultrasound in emergency medicine will rise in the future. In addition, the findings reported here shed new light on the major progress on ultrasound in emergency medicine, which may be mutually cooperative in various fields. Moreover, this bibliometric study provides further indications for the topic of "point-of-care ultrasound".

       BACKGROUND: Osteoarthritis is a common disease among middle-aged and older adults. The arthroscopic approach is among the less traumatic of the treatments and provides quicker recovery. The purpose of this study was to use bibliometrics analysis to clarify the current status and existing problems in the research of the arthroscopic treatment of osteoarthritis.
    METHODS: The Science Citation Index Expanded (SCI-E) database in the Web of Science Core Collection (WOSCC) was used as the data source for the literature search. The search terms were "osteoarthritis" and "arthroscopy", with the intersection of the search results of these 2 search terms being used. CiteSpace software used to analyze the final results of the search in the following aspects: annual publication, subject distribution, country/institution distribution, journal distribution, author distribution, and keyword usage. Finally, burst detection was applied to analyze the annual use trend of the keywords.
    RESULTS: A total of 2,738 document records were retrieved, and the frequency of citations was 82,932 times. The number of publications and the number of citations showed an obvious annual increasing trend. The country with the highest number of publications and centrality was the United States of America, and most important research institutions were from the United States. Extensive cooperation between countries and institutions was evident. The important journals in this field were mainly professional journals of orthopedics and joints. Keyword analysis showed that early research mainly focused on the technical operation of arthroscopic treatment of osteoarthritis, while the focus in recent years has been on long-term prognosis and risk prediction.
    CONCLUSIONS: The application of arthroscopy in the treatment for osteoarthritis should be further explored, especially for large joints other than hip and knee joints.

      Nano-systems (size range: 1 ~ 1000 nm) have been widely investigated as pulmonary drug delivery carriers, and the safety of inhaled nano-systems has aroused general interests. In this work, bibliometric analysis was performed to describe the current situation of related literature, figure out the revolutionary trends, and eventually forecast the possible future directions. The relevant articles and reviews from 2001 to 2020 were retrieved from the Web of Science Core Collection. The documents were processed by Clarivate Analytic associated with Web of Science database, Statistical Analysis Toolkit for Informetric, bibliometric online platform and VOSviewer, and the data were visualized. The bibliometric overview of the literature was described, citation analysis was performed, and research hotspots were showcased. The bibliometric analysis of 3362 documents of interest indicated that most of the relevant source titles were in the fields of toxicology, pharmacy, and materials science. The three research hotspots were the biological process of inhalable nano-systems in vivo, the manufacture of inhalable nano-systems, and the impact of nano-systems on human health in the environment. Toxicity and safety have always been the keywords. The USA was the major contributing country, and international collaboration and co-authorship were common phenomena. The general situation and development trend of literature of inhalable nano-systems were summarized. It was anticipated that bibliometrics analysis could provide new ideas for the future research of inhalable nano-systems.

       PURPOSE: Artificial intelligence (AI) has entered the field of medicine, and ophthalmology is no exception. The objective of this study was to report on scientific production and publication trends, to identify journals, countries, international collaborations, and major MeSH terms involved in AI in ophthalmology research.
    METHODS: Scientometric methods were used to evaluate global scientific production and development trends in AI in ophthalmology using PubMed and the Web of Science Core Collection.
    RESULTS: A total of 1356 articles were retrieved over the period 1966-2019. The yearly growth of AI in ophthalmology publications has been 18.89% over the last ten years, indicating that AI in ophthalmology is a very attractive topic in science. Analysis of the most productive journals showed that most were specialized in computer and medical systems. No journal was found to specialize in AI in ophthalmology. The USA, China, and the UK were the three most productive countries. The study of international collaboration showed that, besides the USA, researchers tended to collaborate with peers from neighboring countries. Among the twenty most frequent MeSH terms retrieved, there were only four related to clinical topics, revealing the retina and glaucoma as the most frequently encountered subjects of interest in AI in ophthalmology. Analysis of the top ten Journal Citation Reports categories of journals and MeSH terms for articles confirmed that AI in ophthalmology research is mainly focused on engineering and computing and is mainly technical research related to computer methods.
    CONCLUSIONS: This study provides a broad view of the current status and trends in AI in ophthalmology research and shows that AI in ophthalmology research is an attractive topic focusing on retinal diseases and glaucoma. This study may be useful for researchers in AI in ophthalmology such as clinicians, but also for scientists to better understand this research topic, know the main actors in this field (including journals and countries), and have a general overview of this research theme.

      Psychopathology networks consist of aspects (e.g., symptoms) of mental disorders (nodes) and the connections between those aspects (edges). This article aims to analyze the research literature on network analysis in psychopathology and mental health for the last ten years. Statistical descriptive analysis was complemented with two bibliometric techniques: performance analysis and co-word analysis. There is an increase in publications that has passed from 1 article published in 2010 to 172 papers published in 2020. The 398 articles in the sample have 1,910 authors in total, being most of them occasional contributors. The Journal of Affective Disorders is the one with the highest number of publications on network analysis in psychopathology and mental health, followed by the Journal of Abnormal Psychology and Psychological Medicine stand out. The present study shows that this perspective in psychopathology and mental health is a recent field of study, but with solid advances in recent years from a wide variety of researchers, mainly from USA and Europe, who have extensively studied symptom networks in depression, anxiety, and post-traumatic stress disorders. However, gaps are identified in other psychological behaviors such as suicide, populations such as the elderly, and gender studies.

       BACKGROUND: Indocyanine green fluorescence cholangiography is a new type of cholangiography that has emerged in recent years. It has many advantages, such as simplicity, safety, and efficiency, and is expected to become a routine procedure for intraoperative cholangiography in the future. However, there is no bibliometric analysis of horizontal generalization in this field. Therefore, this study aims to assess the current research status and developmental trends in this field from a global perspective and to help guide the focus of future research.
    METHODS: This study was conducted by retrieving the literature related to ICG fluorescence cholangiography published in English from 2000 to 2021 from Web of Science. The Histcite. Pro tool was used to analyze the bibliometric indicators, and VOSviewer was used to visualize the research trends and hotspots in this field.
    RESULTS: 192 related studies were finally included. For the past 20 years, the number of related publications in this field have increased yearly, with 2010 being a breakthrough point for research in this field. Research has developed rapidly since 2013 and may continue to expand in the next several years. The USA and Japan play leading roles in this field.

       BACKGROUND: Obstructive sleep apnea (OSA) is a common clinical condition with far-reaching health implications. We aimed to analyze the published articles of OSA and compare the differences in aspects of years, countries, institutions, journals, authors and keywords to evaluate the hotspots and development trends in OSA research.
    METHODS: We screened all associated literature on OSA from Web of Science (WoSCC) during 2011-2020 and analyzed the research trends in this field using the VOS viewer and the online bibliometric analysis platform. The BICOMB and gCLUTO softwares were used to visualize the hotspots in OSA research.
    RESULTS: We screened 24,291 compliant publications. Statistics show that the number of OSA-related publications has increased annually. The United States has been leading in the global research field of OSA. Sleep and breathing have published the most articles on OSA. The University of Pennsylvania is the most prolific research institution, while David Gozal has made significant OSA research contributions. Four research hotspots have been summarized through the 21 most common keywords: (I) operative treatment for children with OSA; (II) risk factors and diagnosis of adult OSA; (III) prevalence of OSA and positive airway pressure treatment; (IV) oxidative stress caused by intermittent hypoxia and complications of OSA such as cardiovascular disease and insulin-resistance. Keywords: "Biomarkers", "Endoscopy", "Bariatric surgery", "Oral appliance", "Oropharyngeal exercises", are gradually emerging in the field of OSA research.
    CONCLUSIONS: Over the past decade, increasing attention has been paid to global OSA-related research. The United States is dominating in the OSA research. China possesses a considerable publication number now, which has grown rapidly in the last decade. However, more attention to publication-quality is needed. Instead of traditional therapies, oral appliance, oropharyngeal exercises and much more new approaches are proven to benefit OSA patients and gradually becoming research hotspots.

       BACKGROUND: Despite recent advances in human immunodeficiency virus-1 (HIV-1) prevention, a fast, safe, and effective vaccine will probably be necessary to end the HIV/AIDS pandemic. This study was conducted to evaluate global research trends and map the key bibliometric indices in HIV-1 genetic diversity from 1998 to 2021.
    METHODS: A comprehensive online search was conducted in the Web of Science Core Collection database to retrieve published literature on HIV-1 genetic diversity. Key bibliometric indicators were calculated and evaluated using HistCiteTM, Bibliometrix: An R-tool, and VOSviewer software for windows.
    RESULTS: A total of 2,060 documents written by 9,201 authors and published in 250 journals were included in the final analysis. Year 2012 was the most productive year with 121 (5.87%) publications. The most prolific author was Shao Yiming (n = 74, 3.59%) from Chinese Center for Disease Control and Prevention. The United States of America was the highly contributing and influential country (n = 681, 33.05%). AIDS Research and Human Retroviruses was the most productive journal (n = 562, 27.2%). Network visualization shows that HIV-1 was the most widely used author keyword.
    CONCLUSION: This study provides global research trends and detailed information on HIV-1 genetic diversity. The amount of scientific literature on HIV-1 genetic diversity research has rapidly increased in the last two decades. The maximum number of articles on HIV-1 genetic diversity was published in developed countries; therefore, a scientific research collaboration among researchers and institutes in low-income countries should be promoted and supported.

      China has been the world's largest emitter of carbon dioxide since 2006. To achieve the goal of carbon neutrality by 2060, social scientists must become involved in China's deep decarbonization process. However, Chinese social scientists have given little attention to climate change in their bibliometric research. Based on the Chinese Social Sciences Citation Index journal catalog of the four essential social sciences, namely, management, economics, politics, and sociology, we used the China National Knowledge Infrastructure database to quantify the extent to which Chinese social scientists are concerned about climate change. The results showed that from 1978 to 2020, 1179 articles on climate change were published in management, economics, politics, and sociology journals, which represented only 26.8% of the 4397 articles published on pollution in the same journals. Politics journals published the most articles (38.76%), while sociology journals published the fewest (2.37%). Thus, Chinese social scientists rarely considered climate change, mainly because this topic remains controversial in some fields and because of the influence of international politics in addition to the promotion and incentive mechanisms for researchers. We analyzed the keywords and evolution of climate change research in the four social sciences and our results show that social scientists should give greater emphasis to climate change in their research.

       PURPOSE: Authorship gender disparities persist across academic disciplines, including oncology. However, little is known about global variation in authorship gender distribution.
    METHODS: This retrospective cross-sectional study describes the distribution of author gender as determined from the first name across variables such as authorship position (first, middle, and last), country region, and country income level. The 608 articles with 5,302 authors included in this analysis were published in the Journal of Clinical Oncology Global Oncology, from its inception in October 2015 through March 2020. Primary outcome measure was author gender on the basis of first name probabilities assessed by genderize.io. World Bank classification was used to categorize the country region and income level. Odds ratios were used to describe associations between female last authorship and representation in other authorship positions.
    RESULTS: Although female authors were in the minority across all authorship positions, they were more under-represented in the last author position with 190 (32.1%) female, compared with 252 (41.4%) female first authors and 1,564 (38.1%) female middle authors. Female authors were most under-represented among authors from low-income countries, where they made up 21.6% of first authors and 9.1% of last authors. Of all the regions, sub-Saharan Africa and South Asia had the lowest percentage of female authors. Compared with articles with male last authors, those with female last authors had odds ratios (95% CI) of 2.2 (1.6 to 3.2) of having female first authors and 1.4 (0.9 to 2.1) of having 50% or more female middle authors.
    CONCLUSION: There are wide regional variations in author gender distribution in global oncology. Female authors remain markedly under-represented, especially in lower-income countries, sub-Saharan Africa, and South Asia. Future interventions should be tailored to mitigate these disparities.

      New technologies in neurorehabilitation is a wide concept that intends to find solutions for individual and collective needs through technical systems. Analysis through citation networks is used to search scientific literature related to a specific topic. On the one hand, the main countries, institutions, and authors researching this topic have been identified, as well as their evolution over time. On the other hand, the links between the authors, the countries, and the topics under research have been analyzed. The publications analysis was performed through the Web of Science database using the search terms "new technolog*," "neurorehabilitation," "physical therapy*," and "occupational therapy*." The selected interval of publication was from 1992 to December 2020. The results were analyzed using CitNetExplorer software. After a Web of Science search, a total of 454 publications and 135 citation networks were found, 1992 being the first year of publication. An exponential increase was detected from the year 2009. The largest number was detected in 2020. The main areas are rehabilitation and neurosciences and neurology. The most cited article was from Perry et al. in 2007, with a citation index of 460. The analysis of the top 20 most cited articles shows that most approach the use of robotic devices and brain-computer interface systems. In conclusion, the main theme was found to be the use of robotic devices to address neuromuscular rehabilitation goals and brain-computer interfaces and their applications in neurorehabilitation.

      Recent statistical and social studies have shown that social media platforms such as Instagram, Facebook, and Twitter contain valuable data that influence human behaviors. This data can be used to track, fight, and control the spread of the COVID-19 and are an excellent asset for analyzing and understanding people's sentiments. Current levels of willingness to receive a COVID-19 vaccination are still insufficient to achieve immunity standards as stipulated by the World Health Organization (WHO). The present study employs bibliometric analysis to uncover trends and research into sentiment analysis and COVID-19 vaccination. A range of analyses is conducted using the open-source tool VOSviewer and Scopus database from 2020-2021 to acquire a deeper insight and evaluate current research trends on COVID-19 vaccines. The quantitative methodology used generates various bibliometric network visualizations and trends as a function of publication metrics such as citation, geographical attributes, journal publications, and research institutions. Results of network visualization revealed that understanding the the-state-of-the-art in applying sentiment analysis to the COVID-19 pandemic is crucial to local government health agencies and healthcare providers to help in neutralizing the infodemic and improve vaccine acceptance.

      Gender parity and authorship diversity are declared goals in the publishing world. This study assessed the progress of authorship gender distribution over a quarter of a century and geographic diversity over the last 15 years in high-impact psychiatric journals. All articles published in 2019 in the American Journal of Psychiatry, the British Journal of Psychiatry, and JAMA Psychiatry were included and compared with data from three points in time starting in 1994. Descriptive statistics were gathered, and chi-square tests were performed. All tests were conducted as two-tailed, and p-values < 0.05 were considered to be statistically significant. Inter-rater reliability was calculated via Cohen's kappa. In 2019 a total of 473 articles were published. Forty percent of all authors, 42.3% of first authors, and 29.4% of senior authors were female. Counting original research articles only, female first authorship reached 50.4%. In the 25-year period between 1994 and 2019, female first (p < .001), female senior (p < .001), and female overall (p < .001) authorship has increased. In the specific period between 2014 and 2019, overall female senior authorship in all articles (p = .940) as well as first (p = .101) and senior (p = .157) in original research plateaued. In non-original research articles, female first authorship was higher in 2019 compared to 2014 (p = .014), whilst female senior authorship plateaued (p = .154). Geographic diversity was low and did not change over time. Gender parity in the subcategory original research articles was reached for the first time in 2019. Senior female authorship and geographic diversity remain areas of concern that need further investigation and specific interventions.

       OBJECTIVES: The aim of the study was to map the recent literature on medication error to monitor the state of research and explore emerging research fronts. Specifically, the co-occurrences analysis aimed to research the conceptual structure of the medication errors, whereas the coauthorship analysis aimed to research the "authorities" that influenced the academic and political discussion on medication errors.
    METHODS: The search for relevant studies was carried out through the Scopus. To map and monitor the state of research on medication error, a preliminary analysis was conducted through the year of publication, type of article, and language. The count of citation shows the most relevant work among those included. Bibliometric analyses were conducted, such as coauthorship analysis and co-occurrences analysis.
    RESULTS: The search strategy yielded 5393 articles. Of these, 1267 articles were included. Four main themes emerged from this bibliometric analysis: (a) the exploration of human factors related to health care professionals that increase the risk of medication error, (b) the investigation of behaviors and strategies that can prevent the error in the preparation and administration stage, (c) the analysis of the benefits related to the presence of the pharmacist in hospital settings, and (d) the exploration of the consequences of a medication error and/or adverse effects of drugs.
    CONCLUSIONS: For the first time, a bibliometric analysis of medication errors research in the world has been conducted and demonstrated that there is a wealth of contributions already being made that are well aligned to the World Health Organization challenge.

       RATIONALE AND OBJECTIVE: The Radiology Research Alliance (RRA) of the Association of University Radiologists (AUR) organized a task force to quantify geographic changes in submissions to and publications within radiology journals over time.
    MATERIALS AND METHODS: Twenty journals were selected: 7 US-based general, 4 European-based general, and 9 subspecialty radiology journals. Journals were solicited for submissions and publications based on country of origin from 2010 -2020. Regression models assessed changes over time across countries, and by continent, with an emphasis on the US and China, for each journal category.
    RESULTS: There were 104,679 publications and 92,446 submissions from 149 countries. Overall, there were significant increases in numbers of publications from Asia (R2 = 0.66, p <0.01), and specifically, China (R2 = 0.87, p <0.01). For US journals, there were increased numbers of publications from Asia (R2 = 0.72, p <0.01) and China (R2 = 0.98, p <0.01), but decreased numbers from North America (R2 = 0.41, p = 0.03). For European journals, there were increased numbers of publications from Asia (R2 = 0.79, p <0.01), North America (R2 = 0.75, p <0.01), and China (R2 = 0.82, p <0.01). For subspecialty journals, there were increased numbers of publications from North America (R2 = 0.38, p = 0.04) and China (R2 = 0.73, p <0.01). There was an acute COVID spike in submissions during 2020, with a continuous increase most notable in China (R2 = 0.96, p <0.01).
    CONCLUSION: In the last decade, the numbers of submissions to and publications within general and subspecialty US and European radiology journals have generally increased around the world, with the largest growth in Asia and in particular China.

      Sustainable finance is a rich field of research. Yet, existing reviews remain limited due to the piecemeal insights offered through a sub-set rather than the entire corpus of sustainable finance. To address this gap, this study aims to conduct a large-scale review that would provide a state-of-the-art overview of the performance and intellectual structure of sustainable finance. To do so, this study engages in a review of sustainable finance research using big data analytics through machine learning of scholarly research. In doing so, this study unpacks the most influential articles and top contributing journals, authors, institutions, and countries, as well as the methodological choices and research contexts for sustainable finance research. In addition, this study reveals insights into seven major themes of sustainable finance research, namely socially responsible investing, climate financing, green financing, impact investing, carbon financing, energy financing, and governance of sustainable financing and investing. To drive the field forward, this study proposes several suggestions for future sustainable finance research, which include developing and diffusing innovative sustainable financing instruments, magnifying and managing the profitability and returns of sustainable financing, making sustainable finance more sustainable, devising and unifying policies and frameworks for sustainable finance, tackling greenwashing of corporate sustainability reporting in sustainable finance, shining behavioral finance on sustainable finance, and leveraging the power of new-age technologies such as artificial intelligence, blockchain, internet of things, and machine learning for sustainable finance.

       BACKGROUND: Industry support is a significant funding source in implant dentistry research, not only to provide regulatory processes, but also to validate and promote products through randomized clinical trials (RCTs). However, industry funding should not affect scientific outcomes.
    PURPOSE: The aim of this study was to investigate whether there is an association between industry support for RCTs in implant dentistry and a greater chance of the reporting of positive outcomes, and whether there are other funding tendencies.
    MATERIALS AND METHODS: Randomized clinical trials from five implant dentistry journals were reviewed. Data were extracted, and descriptive and inferential statistical analyses (α = 0.05), including bivariate and multivariable logistic regression, and Spearman's correlation were performed.
    RESULTS: Two hundred eleven RCTs were included. Industry-funded and -unfunded studies presented similar outcomes, in terms of positive and negative results (p ≥ 0.05). North American and European countries received more industry funding, as did high-income countries, which showed well-established collaboration with each other. Clinical Oral Implants Research and Clinical Implant Dentistry and Related Research published 83.6% of industry-funded articles. Industry-funded studies from middle-income countries established more international collaborations with high-income countries than did unfunded studies. Citation numbers were similar for funded and unfunded studies. The chance of RCTs being industry-funded was higher for high-income (odds ratio [OR] = 3.00; 95% confidence interval [CI], 0.99-9.32; p = 0.05) and North American articles (OR = 3.40; 95% CI, 1.37-8.42; p = 0.008) than in lower-middle-income and other continents, respectively. Higher industry funding was associated with specific topics such as "surgical procedures," "prosthodontics topics," and "implant macrodesign" (OR = 4.7; 95% CI, 1.45-15.20; p = 0.010) and with the increase in numbers of institutions (OR = 1.52; 95% CI, 1.16-2.0; p = 0.002).
    CONCLUSION: The available evidence suggests no association between industry funding and greater chances of the reporting of positive outcomes in implant dentistry RCTs. A strong association was identified in industry trends concerning geographic origins, higher numbers of institutions, and specific research topics.

      Ischemia-reperfusion (I/R) injury is one of the most common phenomena in ischemic disease or processes that causes progressive disability or even death. It has a major impact on global public health. Traditional Chinese medicine (TCM) has a long history of application in ischemic diseases and has significant clinical effect. Numerous studies have shown that the formulas or single herbs in TCM have specific roles in regulating oxidative stress, anti-inflammatory, inhibiting cell apoptosis, etc., in I/R injury. We used bibliometrics to quantitatively analyze the global output of publications on TCM in the field of I/R injury published in the period 2001-2021 to identify research hotspots and prospects. We included 446 related documents published in the Web of Science during 2001-2021. Visualization analysis revealed that the number of publications related to TCM in the field of I/R injury has increased year by year, reaching a peak in 2020. China is the country with the largest number of publications. Keywords and literature analyses demonstrated that neuroregeneration is likely one of the research hotspots and future directions of research in the field. Taken together, our findings suggest that although the inherent limitations of bibliometrics may affect the accuracy of the literature-based prediction of research hotspots, the results obtained from the included publications can provide a reference for the study of TCM in the field of I/R injury.

       Purpose: This study analyzed research trends related to childhood and adolescent cancer survivors (CACS) using word co-occurrence network analysis on studies registered in the Korean Citation Index (KCI).
    Methods: This word co-occurrence network analysis study explored major research trends by constructing a network based on relationships between keywords (semantic morphemes) in the abstracts of published articles. Research articles published in the KCI over the past 10 years were collected using the Biblio Data Collector tool included in the NetMiner Program (version 4), using "cancer survivors", "adolescent", and "child" as the main search terms. After pre-processing, analyses were conducted on centrality (degree and eigenvector), cohesion (community), and topic modeling.
    Results: For centrality, the top 10 keywords included "treatment", "factor", "intervention", "group", "radiotherapy", "health", "risk", "measurement", "outcome", and "quality of life". In terms of cohesion and topic analysis, three categories were identified as the major research trends: "treatment and complications", "adaptation and support needs", and "management and quality of life".
    Conclusion: The keywords from the three main categories reflected interdisciplinary identification. Many studies on adaptation and support needs were identified in our analysis of nursing literature. Further research on managing and evaluating the quality of life among CACS must also be conducted.

       OBJECTIVE: Our specific aim was to assess the gender distribution of aspects of scholarly productivity and professional standing for pediatric hospital medicine over a 5-year period. We also evaluated for correlation between the makeup of editorial boards, conference planning committees, and chosen content.
    METHODS: We reviewed scholarly publications, presentations, editorial boards, planning committees, awardees, and society leadership in pediatric hospital medicine from 2015 to 2019 and determined gender using published methods to assess for differences between observed proportions of women authors and presenters and the proportion of women in the field.
    RESULTS: The field of pediatric hospital medicine at large is 69% women (95% confidence internal [CI] 68%-71%), and an estimated 57% of senior members are women (95% CI 54%-60%). We evaluated 570 original science manuscripts and found 67% (95% CI 63%-71%) women first authors and 49% (95% CI 44%-53%) women senior authors. We evaluated 1093 presentations at national conferences and found 69% (95% CI 65%-72%) women presenters of submitted content and 44% (95% CI 37%-51%) women presenters of invited content. Senior authorship and invited speaking engagements demonstrated disproportionately low representation of women when compared with senior members of the field (senior authorship, P = .002; invited presenters, P < .001). Strong positive correlation between gender composition of conference planning committees and selected content was also noted (r = 0.94).
    CONCLUSION: Our study demonstrated representative gender distribution for some aspects of scholarly productivity in pediatric hospital medicine; however, a lack of gender parity exists in senior roles.

      Micro- and macroparasites are a leading cause of mortality for humans, animals, and plants, and there is great need to understand their origins, transmission dynamics, and impacts. Disease ecology formed as an interdisciplinary field in the 1970s to fill this need and has recently rapidly grown in size and influence. Because interdisciplinary fields integrate diverse scientific expertise and training experiences, understanding their composition and research priorities is often difficult. Here, for the first time, we quantify the composition and educational experiences of a subset of disease ecology practitioners and identify topical trends in published research. We combined a large survey of self-declared disease ecologists with a literature synthesis involving machine-learning topic detection of over 18,500 disease ecology research articles. The number of graduate degrees earned by disease ecology practitioners has grown dramatically since the early 2000s. Similar to other science fields, we show that practitioners in disease ecology have diversified in the last decade in terms of gender identity and institution, with weaker diversification in race and ethnicity. Topic detection analysis revealed how the frequency of publications on certain topics has declined (e.g., HIV, serology), increased (e.g., the dilution effect, infectious disease in bats), remained relatively common (e.g., malaria ecology, influenza, vaccine research and development), or have consistently remained relatively infrequent (e.g., theoretical models, field experiments). Other topics, such as climate change, superspreading, emerging infectious diseases, and network analyses, have recently come to prominence. This study helps identify the major themes of disease ecology and demonstrates how publication frequency corresponds to emergent health and environmental threats. More broadly, our approach provides a framework to examine the composition and publication trends of other major research fields that cross traditional disciplinary boundaries.

      Considering the physical, and psychological impacts and challenges brought about the coronavirus disease 2019 (COVID-19), art therapy (AT) provides opportunities to promote human health and well-being. There are few systematic analysis studies in the fields of AT, which can provide content and direction for the potential value and impact of AT. Therefore, this paper aims to critically analyze the published work in the field of AT from the perspective of promoting health and well-being, and provides insights into current research status, hotspots, limitations, and future development trends of AT. This paper adopts a mixed method of quantitative and qualitative analysis including bibliometric analysis and keyword co-occurrence analysis. The results indicate that: (1) the current studies on AT are mostly related to research and therapeutic methods, types of AT, research populations and diseases, and evaluation of therapeutic effect of AT. The research method of AT mainly adopts qualitative research, among which creative arts therapy and group AT are common types of AT, and its main research populations are children, veterans, and adolescents. AT-aided diseases are trauma, depression, psychosis, dementia, and cancer. In addition, the therapeutic methods are mainly related to psychotherapy, drama, music, and dance/movement. Further, computer systems are an important evaluation tool in the research of AT; (2) the future development trend of AT-aided health and well-being based on research hotspots, could be focused on children, schizophrenia, well-being, mental health, palliative care, veterans, and the elderly within the context of addressing COVID-19 challenges; and (3) future AT-aided health and well-being could pay more attention to innovate and integrate the therapeutic methods of behavior, movement, and technology, such as virtual reality and remote supervision.

      Machine learning applications are becoming more ubiquitous in dairy farming decision support applications in areas such as feeding, animal husbandry, healthcare, animal behavior, milking and resource management. Thus, the objective of this mapping study was to collate and assess studies published in journals and conference proceedings between 1999 and 2021, which applied machine learning algorithms to dairy farming-related problems to identify trends in the geographical origins of data, as well as the algorithms, features and evaluation metrics and methods used. This mapping study was carried out in line with PRISMA guidelines, with six pre-defined research questions (RQ) and a broad and unbiased search strategy that explored five databases. In total, 129 publications passed the pre-defined selection criteria, from which relevant data required to answer each RQ were extracted and analyzed. This study found that Europe (43% of studies) produced the largest number of publications (RQ1), while the largest number of articles were published in the Computers and Electronics in Agriculture journal (21%) (RQ2). The largest number of studies addressed problems related to the physiology and health of dairy cows (32%) (RQ3), while the most frequently employed feature data were derived from sensors (48%) (RQ4). The largest number of studies employed tree-based algorithms (54%) (RQ5), while RMSE (56%) (regression) and accuracy (77%) (classification) were the most frequently employed metrics used, and hold-out cross-validation (39%) was the most frequently employed evaluation method (RQ6). Since 2018, there has been more than a sevenfold increase in the number of studies that focused on the physiology and health of dairy cows, compared to almost a threefold increase in the overall number of publications, suggesting an increased focus on this subdomain. In addition, a fivefold increase in the number of publications that employed neural network algorithms was identified since 2018, in comparison to a threefold increase in the use of both tree-based algorithms and statistical regression algorithms, suggesting an increasing utilization of neural network-based algorithms.

       OBJECTIVE: Antimicrobial resistance (AMR) is a global threat to health and healthcare. In response to the growing AMR burden, research funding also increased. However, a comprehensive overview of the research output, including conceptual, temporal, and geographical trends, is missing. Therefore, this study uses topic modelling, a machine learning approach, to reveal the scientific evolution of AMR research and its trends, and provides an interactive user interface for further analyses.
    METHODS: Structural topic modelling (STM) was applied on a text corpus resulting from a PubMed query comprising AMR articles (1999-2018). A topic network was established and topic trends were analysed by frequency, proportion, and importance over time and space.
    RESULTS: In total, 88 topics were identified in 158,616 articles from 166 countries. AMR publications increased by 450% between 1999 and 2018, emphasizing the vibrancy of the field. Prominent topics in 2018 were Strategies for emerging resistances and diseases, Nanoparticles, and Stewardship. Emerging topics included Water and environment, and Sequencing. Geographical trends showed prominence of Multidrug-resistant tuberculosis (MDR-TB) in the WHO African Region, corresponding with the MDR-TB burden. China and India were growing contributors in recent years, following the United States of America as overall lead contributor.
    CONCLUSION: This study provides a comprehensive overview of the AMR research output thereby revealing the AMR research response to the increased AMR burden. Both the results and the publicly available interactive database serve as a base to inform and optimise future research.

      Dominance hierarchies have been studied for almost 100 years. The science of science approach used here provides high-level insight into how the dynamics of dominance hierarchy research have shifted over this long timescale. To summarize these patterns, I extracted publication metadata using a Google Scholar search for the phrase 'dominance hierarchy', resulting in over 26 000 publications. I used text mining approaches to assess patterns in three areas: (1) general patterns in publication frequency and rate, (2) dynamics of term usage and (3) term co-occurrence in publications across the history of the field. While the overall number of publications per decade continues to rise, the percent growth rate has fallen in recent years, demonstrating that although there is sustained interest in dominance hierarchies, the field is no longer experiencing the explosive growth it showed in earlier decades. Results from title term co-occurrence networks and community structure show that the different subfields of dominance hierarchy research were most strongly separated early in the field's history while modern research shows more evidence for cohesion and a lack of distinct term community boundaries. These methods provide a general view of the history of research on dominance hierarchies and can be applied to other fields or search terms to gain broad synthetic insight into patterns of interest, especially in fields with large bodies of literature. This article is part of the theme issue 'The centennial of the pecking order: current state and future prospects for the study of dominance hierarchies'.

      The main purpose of this short communication is to identify and analyze retracted editorials in the biomedical literature. Twenty-five of the 33 editorials are chosen for further analysis. All of the editorials were published as commentaries and concise reviews between 1998 and 2021. Due to plagiarism and data-related issues, the majority of the editorial articles were retracted. Alarmingly, one-fifth of the editorials were funded by external agencies, with the USA leading the list of retracted editorials. The average time between the publication of the editorials and their retraction is 2.48 years, and two editorials were retracted with the longest durations; both were written by the same author. The conclusion is that, at the very least, editorial articles should be devoid of research/scientific misconduct.

       BACKGROUND: With the COVID-19 pandemic's outbreak, millions flocked to Wikipedia for updated information. Amid growing concerns regarding an "infodemic," ensuring the quality of information is a crucial vector of public health. Investigating whether and how Wikipedia remained up to date and in line with science is key to formulating strategies to counter misinformation. Using citation analyses, we asked which sources informed Wikipedia's COVID-19-related articles before and during the pandemic's first wave (January-May 2020).
    RESULTS: We found that coronavirus-related articles referenced trusted media outlets and high-quality academic sources. Regarding academic sources, Wikipedia was found to be highly selective in terms of what science was cited. Moreover, despite a surge in COVID-19 preprints, Wikipedia had a clear preference for open-access studies published in respected journals and made little use of preprints. Building a timeline of English-language COVID-19 articles from 2001-2020 revealed a nuanced trade-off between quality and timeliness. It further showed how pre-existing articles on key topics related to the virus created a framework for integrating new knowledge. Supported by a rigid sourcing policy, this "scientific infrastructure" facilitated contextualization and regulated the influx of new information. Last, we constructed a network of DOI-Wikipedia articles, which showed the landscape of pandemic-related knowledge on Wikipedia and how academic citations create a web of shared knowledge supporting topics like COVID-19 drug development.
    CONCLUSIONS: Understanding how scientific research interacts with the digital knowledge-sphere during the pandemic provides insight into how Wikipedia can facilitate access to science. It also reveals how, aided by what we term its "citizen encyclopedists," it successfully fended off COVID-19 disinformation and how this unique model may be deployed in other contexts.

       Background: Coronavirus disease-19 (COVID-19) is an infectious disease transmitted by the virus responsible for the severe acute respiratory syndrome 2 (SARS-CoV-2), which exhibit several clinical manifestations including gastrointestinal symptoms.
    Scope and approach: This review aimed to provide insights and perspectives for the use of probiotics, prebiotics, synbiotics, and postbiotics as adjuvants for prevention/treatment and/or modulation of the microbiota in COVID-19 patients. Eighty-four studies published in the Scopus database from the onset of the pandemic until December 2021 were assessed and submitted to a bibliometric analysis adapted from VOSviewer software.
    Key findings and conclusions: Through bibliometric analysis, it might be suggested that the modulation of the gut/lung microbiome is promising as an adjuvant for the prevention/treatment of COVID-19 patients, due to immunomodulation properties related to probiotics and prebiotics. So far, few clinical studies involving the application of probiotics in COVID-19 patients have been completed, but reduction in the duration of the disease and the severity of symptoms as fatigue, olfactory dysfunction and breathlessness, nausea and vomiting and other gastrointestinal symptoms were some of the main findings. However, probiotics are not recommended to immunocompromised patients in corticosteroid therapy. The future perspectives point to the modulation of the intestinal microbiota by probiotics, prebiotics, synbiotics, and postbiotics represent a promising adjuvant approach for improving the health of patients with COVID-19.

       INTRODUCTION: Division chiefs (DCs) play an integral role within the department, making critical decisions and helping shape the future of both the division and the department. This study aimed to investigate the demographic characteristics and scholarly work of DCs in academic orthopaedic sports medicine division in the United States.
    METHODS: Orthopaedic residency programs at academic centers were identified using the Association of American Medical Colleges' Electronic Residency Application Service. DCs were identified using the program's respective websites where data points such as sex, race/ethnicity, fellowship training institution, time since graduating fellowship, academic rank, number of degrees, and additional leadership titles were collected. Scopus database was used to determine h-indices.
    RESULTS: From the 191 programs identified, 100 had a DC for the sports medicine subspecialty division, and 66 programs offered a sports medicine fellowship. Most DCs (96%) were men. The racial/ethnic demographics of the DCs were mostly White (86%), followed by Asian (11%), African American (1%), Hispanic/Latino (1%), and mixed ethnicity (1%). On average, the DCs were 19.6 years past their fellowship completion. The average h-index was 21.2. Many (48%) had an academic rank of professor, 28% associate professor, and 12% assistant professor. Four held additional graduate degrees. The fellowship programs that trained the most DCs were Hospital for Special Surgery (11), Kerlan Jobe Orthopaedic Clinic (8), University of Pittsburgh (7), American Sports Medicine Institution (5), Cleveland Clinic (5), Cincinnati Sports Medicine (4), Massachusetts General Hospital (4), and Steadman Hawkins Clinic (4).
    DISCUSSION: DCs in academic orthopaedic surgery plays a crucial role in the department and is a topic that is understudied. A lack of diversity exists among DCs in academic Sports Medicine in orthopaedics. The position is held predominately by White men with a rank of either full or associate professor and extensive leadership experience. More efforts are needed to increase the diversity of sports medicine leadership within academic orthopaedic programs in the United States.

       Background: Ginseng has a long history of widespread use and remarkable effects as traditional medicine, adjuvant and dietary supplement. The therapeutic value, diverse functionalities and rapid development of ginseng have driven a significant increase in the number of ginseng clinical trials, ranging from its use in various ailments, formulation to safety concerns. Despite the persistent interest in ginseng clinical research, the medical effectiveness of ginseng is inconclusive and there is a lack of bibliometric analysis of the hundreds of ginseng clinical trials.
    Aim of Review: This review aims to provide an extensive overview of ginseng clinical trials over the past 40 years (1979-2018) in combination with a qualitative and quantitative analysis. The annual clinical trial analysis of time distribution, country and institution network analysis for space cooperation, statistical analysis for various functions, as well as efficiency and effect size were performed for global ginseng clinical trials. Besides, preparation categories, administration routes, and the safety of ginseng clinical trials were also investigated.
    Key Scientific Concepts of Review: The 40-year journey of ginseng clinical trials has experienced emerging, boom, and stable or transitional stages. The global network of ginseng clinical trials has relevant regional distribution in Asia, North America and Europe. South Korea makes a great contribution to building up large research clusters and strong cooperation links. Universities are the key contributors to ginseng clinical trials. The development of ginseng products could be focused on the clinical trial in diseases with higher effectiveness or effect size, such as sexual function and cognitive & behavior and require rigorous investigations and evidence to evaluate safety. More attention should be paid to different effects from different preparations. We believe this review will provide new insights into the understanding of global ginseng clinical trials and identifies potential future perspectives for research and development of ginseng.

       OBJECTIVE: In 2017, the National Institute for Health Research (NIHR) academy produced a strategic review of training, which reported the variation in application characteristics associated with success rates. It was noted that variation in applicant characteristic was not independent of one another. Therefore, the aim of this secondary analysis was to investigate the inter-relationships in order to identify factors (or groups of factors) most associated with application numbers and success rates.
    DESIGN: Retrospective data were gathered from 4388 applications to NIHR Academy between 2007 and 2016. Multinominal logistic regression models quantified the likelihood of success depending on changes in the explanatory factors; relative risk ratios with 95% CIs. A classification tree analysis was built using exhaustive χ2 automatic interaction detection to better understand the effect of interactions between explanatory variables on application success rates.
    RESULTS: 936 (21.3%) applications were awarded. Applications from males and females were equally likely to be successful (p=0.71). There was an overall reduction in numbers of applications from females as award seniority increased from predoctoral to professorship. Applications from institutions with a medical school had a 2.6-fold increase in likelihood of success (p<0.001). Classification tree analysis revealed key predictors of application success: award level, type of programme, previous NIHR award experience and applying form a medical school.
    CONCLUSION: Success rates did not differ according to gender, and doctors were not more likely to be successful than applications from other professions. Taken together, these findings suggest an essential fairness in how the quality of a submitted application is assessed, but they also raise questions about variation in the opportunity to submit a high-quality application. The companion qualitative study (Burkshaw et al. (2021) BMJ Open) provides valuable insight into potential candidate mechanisms and discusses how research capacity development initiatives might be targeted in the future.

      The world is undergoing exponential urbanization, with consequences for society in general, both for cities and people, with serious economic, social and environmental implications. Therefore, it is crucial to reconsider urban models of cities, to ensure global, long-term sustainability. Numerous researchers have argued that one of these models involves eco-city projects, and this study aims to carry out a systematic review of the literature on this topic, through bibliometrics. To do so, the Smarter, Prisma and Vantage Point methods were used, reflecting the originality of the study. The results obtained show that China has aroused researchers' interest regarding its eco-city projects, with most studies being empirical, and so this study complements them. The main contribution of this research lies in identifying the keywords most used by authors, these being eco-cities, sustainable cities (cluster 1) and eco-cities, China, sustainable urban development and eco-cycle model (cluster 2). Finally, implications for theory and practice are presented, together with suggestions for future research.
