      Background: The Middle East respiratory syndrome coronavirus (MERS-CoV) was first reported in Saudi Arabia in 2012. So far, the cases of MERS-CoV have been reported in 27 countries. The virus causes severe health complications, resulting high mortality.Aim: The current study aimed to evaluate the global research trends and key bibliometric indices in MERS-CoV research from 2012 to 2021.
    Methods: A retrospective bibliometric and visualized study was conducted. The Science Citation Index Expanded Edition of Web of Science Core Collection database was utilized to retrieve published scientific literature on MERS-CoV. The retrieved publications were assessed for a number of bibliometric attributes. The data were imported into HistCiteTM and VOSviewer software to calculate the citations count and perform the visualization mapping, respectively. In addition, countries or regions collaboration, keywords analysis, and trend topics in MERS-CoV were assessed using the Bibliometrix: An R-tool.
    Results: A total of 1,587 publications, published in 499 journals, authored by 6,506 authors from 88 countries or regions were included in the final analysis. Majority of these publications were published as research article (n = 1,143). Globally, these publications received 70,143 citations. The most frequent year of publication was 2016 (n = 253), while the most cited year was 2014 (11,517 citations). The most prolific author was Memish ZA (n = 94), while the most published journal was Emerging Infectious Diseases (n = 80). The United States of America (USA) (n = 520) and Saudi Arabia (n = 432) were the most influential and largest contributors to the MERS-CoV publications. The extensively studied research area was infectious diseases. The most frequently used author keywords other than search keywords were Saudi Arabia, SARS-CoV-2, COVID-19, epidemiology, transmission, spike protein, vaccine, outbreak, camel, and pneumonia.
    Conclusion: This study provides an insight into MERS-CoV-related research for scientific community (researchers, academicians) to understand and expand the basic knowledge structure, potential collaborations, and research trend topics. This study can also be useful for policy makers. After the emergence of MERS-CoV, a significant increase in scientific production was observed in the next 4 years (2013-2016). In 2021, the trend topics in MERS-CoV-related research were COVID-19, clinical characteristics, and cytokine storm. Saudi Arabia had the strongest collaboration with the USA, while the USA had the highest collaboration with China.

      Objective: The objective of this study was the visualization of hot spots and evolving trends in research on the association between vitamin D and infections through the use of bibliometric analysis.Methods: Based on 3046 relevant articles collected in the Web of Science Core Collection for the period of 2001-2021, the data were processed using CiteSpace software. GraphPad software was used for some of the graphics.
    Results: A total of 3,046 literature were retrieved, with an average citation frequency of 27.89 times. The number of published papers in the direction of "Immunology" (453 articles, 14.9%) and "Infectious diseases" (312 articles, 10.2%) is much higher. The United States presents the highest publication count (890, 29.2%) and shows a strong leadership in this field. Country burst shows that since 2015, many developing countries and low-income countries have carried out enthusiastic research in this regard, including China, Pakistan, and Iran. As for institutions, the League of European Research Universities produces a larger proportion of articles (220, 7.2%). In terms of authors, Martineau AR and Camargo CA have the highest number of published articles, contributing 30 (0.99%) and 28 articles (0.92%), respectively. Major studies are supported by the United States Department of Health Human Services funding (394, 12.9%). According to the keyword co-occurrence diagram, the 10 most frequent keywords from 2001 to 2021 are "vitamin D", "infection", "d deficiency", "risk", "association", "expression", "disease", "d supplementation", "vitamin d deficiency", and "children". The top 10 cited articles in 2021 are all related to COVID-19, suggesting it is a hotspot in recent times.
    Conclusion: Research on the association between vitamin D and infection has grown rapidly since 2012 and is generally developing well. While developed Western countries continue to be leading roles in this field, research trends in developing countries are also very promising. It is demonstrated that the relationship between vitamin D and respiratory infections, especially respiratory viruses and the more recently COVID-19, has received a lot of attention in the last two decades, suggesting that this is the hotspot and frontier of research issue.

      Introduction: Glucocorticoid-induced osteoporosis (GIOP) is the most common cause of secondary osteoporosis. Although many studies related to GIOP have been published, there was no bibliometric analysis in this field. This study aimed to investigate the research trends on GIOP by using bibliometric analysis.Materials and Methods: All data were collected from the Web of Science Core Collection (WoSCC). All original research articles regarding GIOP from 2012 to 2021 were retrieved. CiteSpace was used to analyze the distribution of countries, institutions, journals, authors, and keywords. We revealed hotspots and trends in the field by drawing co-occurrence keyword maps and identifying burst keywords.
    Results: From 2012 to 2021, 685 relevant articles were published, with a peak in 2018 in the annual number of publications. China and McMaster University were the leading country and institution in this field with 208 and 12 publications, respectively. Osteoporosis International was the journal with the most studies, while Journal of Bone and Mineral Research was the most cited journal. "Bone mineral density", "fracture", "postmenopausal women", "prevention" and "therapy" were the most high-frequency keywords, while "bone mineral density", "bisphosphonate" and "metabolism" were the top high-centrality keywords.
    Conclusion: The results from this bibliometric study provided insight into the status and research trends in GIOP of the past decade, which could help researchers quickly determine the current hotspots and frontier trends in this field.

      The earliest publication related to mushroom poisoning dates back to 1837. To date, bibliometric analysis related to the field of mushroom poisoning has not been published. This study aimed to assess the most significant publications in this field as well as the associated trends and important drivers in the research related to mushroom poisoning. The Scopus database was screened to identify relevant publications on mushroom poisoning. A total of 985 publications with a minimum of five citations were identified and analyzed. Pearson's correlation demonstrated an insignificant weak negative correlation (Pearson's correlation of -0.020, P > 0.01) between the number of years since publication and the number of citation counts of a paper. Bradford's law of scattering revealed that one-third of publications were published in 31 core journals, with Clinical Toxicology topping the list (41 papers). VOSviewer was used to generate a network visualization based on country. The United States was the largest contributor of publications on mushroom poisoning, contributing 19.6% of 985. China is an emerging leader in publications on mushroom poisoning research since 2011, with the most recent average publication year of 2011.18. A term map was also created to visualize the co-occurrence of key terms, whereby Amanita phalloides-related research appeared to be the most frequently published topic in this field. In conclusion, the results of this bibliometric study shed light on the status of mushroom poisoning research and can guide investigators on current research trends for high-impact knowledge contribution in the field.

      Introduction: As the first bibliometric analysis of COVID-19 and immune responses, this study will provide a comprehensive overview of the latest research advances. We attempt to summarize the scientific productivity and cooperation across countries and institutions using the bibliometric methodology. Meanwhile, using clustering analysis of keywords, we revealed the evolution of research hotspots and predicted future research focuses, thereby providing valuable information for the follow-up studies.Methods: We selected publications on COVID-19 and immune response using our pre-designed search strategy. Web of Science was applied to screen the eligible publications for subsequent bibliometric analyses. GraphPad Prism 8.0, VOSviewer, and CiteSpace were applied to analyze the research trends and compared the contributions of countries, authors, institutions, and journals to the global publications in this field.
    Results: We identified 2,200 publications on COVID-19 and immune response published between December 1, 2019, and April 25, 2022, with a total of 3,154 citations. The United States (611), China (353), and Germany (209) ranked the top three in terms of the number of publications, accounting for 53.3% of the total articles. Among the top 15 institutions publishing articles in this area, four were from France, four were from the United States, and three were from China. The journal Frontiers in Immunology published the most articles (178) related to COVID-19 and immune response. Alessandro Sette (31 publications) from the United States were the most productive and influential scholar in this field, whose publications with the most citation frequency (3,633). Furthermore, the development and evaluation of vaccines might become a hotspot in relevant scope.
    Conclusions: The United States makes the most indispensable contribution in this field in terms of publication numbers, total citations, and H-index. Although publications from China also take the lead regarding quality and quantity, their international cooperation and preclinical research need to be further strengthened. Regarding the citation frequency and the total number of published articles, the latest research progress might be tracked in the top-ranking journals in this field. By analyzing the chronological order of the appearance of retrieved keywords, we speculated that vaccine-related research might be the novel focus in this field.

      The World Health Organization recognizes noma as a global health problem and has suggested prioritizing research into this disease. A bibliographic search of original articles published in the Web of Science database up to 2022 was performed. A bibliometric analysis was carried out with the bibliometrix package in R and VOSviewer. We identified 251 articles published in 130 journals. The first publication was in 1975, the highest number of publications was in 2003, and the average number of citations per document was 12.59. The author with the highest number of publications was Enwonwu CO, and the Noma Children's Hospital had the highest number of articles on this topic. Plastic and Reconstructive Surgery was the journal with the most publications, and the study by Petersen PE was the most cited. The country of corresponding authors that had the most publications and the most significant number of total citations was the United States. "Children" and "Reconstruction" were the most used keywords. In conclusion, there are few publications on noma worldwide, confirming the neglected status of this disease. Urgent actions are needed to increase evidence in regard to the epidemiology of noma and public health interventions to mitigate the ravages of this disease.

      BACKGROUND: Tuberculosis (TB) is still a leading global cause of mortality and an increasingly crucial problem in fighting TB is antibiotic resistance. We aimed to conduct a bibliometric analysis on the articles of the past 25 years on antibiotic-resistant active pulmonary TB.METHODS: Appropriate keywords were combined using the Boolean and wildcard operators and searched in Scopus database for articles published between 1996 and 2020 in English language. For all the bibliometric analyses, the Bibliometrix package in RStudio and Biblioshiny web apps were used. We identified the publication and citation trends, topmost cited documents, most productive authors, countries and institutions and most influential journals and funding agencies. We constructed collaborative networks of countries and co-citations. In addition, we developed a Three-Fields plot and a Thematic Map to explore different publication themes.
    RESULTS: We included 7024 articles (88.9% research articles) and a persistently increasing publication and citation trends were evident throughout the past 25 years. Boehme 2010 was the most cited paper (1609 times cited), Stefan Niemann was the most productive author (86 papers), and 'International Journal of Tuberculosis and Lung Disease' was the leading journal. Centers for Disease Control and Prevention was the top contributing institution (3.7% papers) and both US- and UK-based funders were leading. The most productive countries were the USA, India, the UK, South Africa, and China and most of the collaborations took place between the USA, the UK, and South Africa.
    CONCLUSION: Undoubtedly, researchers and funders from the USA dominated followed by the UK in most of the fields in antibiotic-resistant TB research. The outcomes of antibiotic-resistant TB research would be more productive and translational if researchers from low- or middle-income countries (especially from Africa, South America and Asia) with high research productivity and TB burden could be in collaboration with high-income countries exhibiting low TB burden.

      Background: Since Lambotte and Payr first studied Mg-based alloys for orthopedics in 1900, the research of this field has finally ushered in vigorous development in the 21st century. From the perspective of quantitative analysis, this paper clearly demonstrated the global research trend from 2005 to 2021 by using bibliometrics and scientometric analysis. Methods: We obtained the publications from the Web of Science Core Collection (WoSCC) database. The bibliometric and scientometric analysis was conducted by using R software, CiteSpace software, VOSviewer software, Pajek software and Microsoft Excel program. Results: In total, 1921 publications were retrieved. It can be found that the number of publications is gradually increasing year by year. We can find that the most prolific countrie, institution and researcher are China, Chinese Academy of Sciences and Zheng Yufeng, respectively. The most influential journals in this field are Acta Biomaterialia and Biomaterials, with 16,511 and 12,314 total citations, respectively. By conducting the co-cited documents-based clustering analysis, 16 research hotspots and their representative studies have been identified. Besides, by conducting analysis of keywords, we divided the keyword citation bursts representing the development of the field into three stages. Conclusion: The number of researches on the biodegradable Mg-based alloys increased sharply all over the world in the 21st century. China has made significant progress in biodegradable Mg-based alloy research. More focus will be placed on osteogenic differentiation, fabrication, graphene oxide, antibacterial property, bioactive glass and nanocomposite, which may be the next popular topics in the field.

      BACKGROUND: Authorship and author order have been used as one measure to characterise equity in research partnerships. First and last (senior) authorships often denote scientific merit as well as potential for research career advancement. A previous analysis found that only about 20%-25% of publications about Africa with coauthors from top-ranking US universities had a first or last author from the topic country. In this bibliometric analysis, we evaluated authorship of publications about sub-Saharan Africa (SSA) funded by the Fogarty International Center (FIC) of the US National Institutes of Health, an institution with a mission of training and capacity building in low-income and middle-income countries.METHODS: We analysed publications from PubMed and Web of Science that were funded by FIC, about SSA, and published between 2008 and 2020. Relative citation ratio (RCR) data from iCite were used to compare group citation impact measures using the Wilcoxon rank sum test.
    RESULTS: A total of 3446 publications met the inclusion criteria, with annual number increasing from 114 in 2008 to 352 in 2020. SSA-affiliated first authors increased from 53 (47%) in 2008 to 224 (63%) in 2020. SSA-affiliated last authors increased from 32 (28%) to 166 (47%). For both first and last authorships, the median RCR value of publications with SSA-affiliated authors was lower than for US-affiliated authors (first authors: 0.84 vs 0.95, p=0.0021; last authors: 0.88 vs 0.91, p=0.010).
    CONCLUSION: The increase in first and last authorships by SSA-affiliated authors of publications about SSA suggests increasing equity in research activities funded by FIC. Further investigation and actions are needed to establish how authorship reflects other aspects of equity, the implication of the lower RCR in papers with SSA-affiliated first and last authors and what policies and practices are needed to further promote equity in global health research.

      Radiotherapy for rectal cancer has received increasing research attention in recent years; however, no bibliometric assessment has been conducted on the progress of research in this field. This study aimed to visualize the research evolution and emerging research hotspots in the field of rectal cancer radiotherapy using bibliometric methods. Data were collected from the Web of Science Core Collection database, including countries, institutions, authors, keywords, and co-citations of references, and the CiteSpace software was used for bibliometric analysis. A total of 5,372 publications on radiotherapy for rectal cancer, published between January 2000 and January 2022, were included. An increasing trend in the number of published articles was observed. There is an overall upward trend in the number of publications published, with the US publishing the most in this field, followed by China and the Netherlands. Italian writer Vincenzo Valentini and German writer R. Sauer ranked first in terms of published articles and co-cited authors, respectively. Literature co-citation and keyword co-occurrence analyses showed that early studies focused on topics such as preoperative radiotherapy, combined radiotherapy and chemotherapy, and total mesorectal excision. In recent years, gradually increasing attention has been paid to short-course radiotherapy, x-ray brachytherapy, and stereotactic systemic radiotherapy. Burst analysis suggested that magnetic resonance (MR)-guided neoadjuvant radiotherapy studies, mechanistic studies, and clinical trials may emerge as new research hotspots. Rectal cancer radiotherapy has been widely studied and the research hotspots have considerably changed in recent years. Future research hotspots may include MR-guided neoadjuvant radiotherapy studies, mechanistic studies, and clinical trials.

      BACKGROUND: Pediatric minimally invasive surgery (MIS) is a standard technique worldwide. We aimed to analyze the research activity in this field.METHODS: Articles on pediatric MIS (1991-2020) were analyzed from the Web of Science™ for the total number of publications, citations, journals, and impact factors (IF). Of these, the 50 most cited publications were evaluated in detail and classified according to the level of evidence (i.e., study design) and topic (i.e., surgical procedure).
    RESULTS: In total, 4464 publications and 53,111 citations from 684 journals on pediatric MIS were identified. The 50 most cited papers were published from 32 institutions in the USA/Canada (n = 28), Europe (n = 19), and Asia (n = 3) in 12 journals. Four authors (USA/Europe) contributed to 26% of the 50 most cited papers as first/senior author. Hot topics were laparoscopic pyeloplasty (n = 9), inguinal hernia repair (n = 7), appendectomy, and pyloromyotomy (n = 4 each). The majority of publications were retrospective studies (n = 33) and case reports (n = 6) (IF 5.2 ± 3.2; impact index 16.5 ± 6.4; citations 125 ± 39.4). They were cited as often as articles with high evidence levels (meta-analyses, n = 2; randomized controlled trials, n = 7; prospective studies, n = 2) (IF 12.9 ± 22.5; impact index 14.0 ± 6.5; citations 125 ± 34.7; p > 0.05).
    CONCLUSIONS: Publications on laparoscopic pyeloplasty, inguinal hernia repair, appendectomy, and pyloromyotomy are cited most often in pediatric MIS. However, the relevant number of studies with strong evidence for the advantages of MIS in pediatric surgery is missing.

      Polyaniline (PANI), which is a member of the family of electrically conducting polymers, has been widely discussed as a potential membrane for wastewater treatment. Although a steady growth in PANI literature was observed, analyzing PANI literature quantitatively is still a novelty. The main aim of this study is to unearth the current research status, global trends, and evolution of PANI membranes literature and their use in water treatment applications over time. For this purpose, a scientometric study was performed consisting of bibliometric and bibliographic analysis. A total of 613 entities were extracted from Web of Science published during the last 50 years and were analyzed to map trends based on leading peer-reviewed journals, publication records, leading research disciplines, countries, and organizations. The study shows that the number of annual publications increased exponentially from 2005 to 2020 and is expected to keep increasing in the current decade. The Journal of Membrane Science published the highest number of articles and was identified as the most-cited journal in the field. China, India, and the USA were observed as the top three research hubs. The top-ranked authors in the field were Wang, Jixiao, and Wang, Zhi. To find research trends, four different clusters of keywords were generated and analyzed. The top five most frequent keywords turn out to be polyaniline, water, performance, membranes, and nanoparticles. The analysis suggests that the application of nanotechnology for modifying PANI membranes (using nanoparticles, nanotubes, and graphene specifically) is the future of this field. This study elucidates the research streamline of the field that may serve as a quick reference for early career researchers and industries exploring this field.

It is very important to understand the occurrence and development of PCa for early diagnosis, treatment and metastasis control. This study aims to elucidate the international frontier research direction and literature distribution through bibliometric and visual analyses of PCa bone metastasis.Methods: Data were obtained from the Web of Science core collection database, which collected 2,246 papers related to PCa bone metastasis from 1 January 2012 to 31 December 2021. The collected data were analyzed using the VOSviewer software for citation, co-authorship, co-citation, bibliometric coupling, and co-occurrence.
    Results: Over the past decade, published papers have increased annually. The United States of America has published 890 papers with 29,161 citations, far more than any other country, and it has the most extensive collaboration with other countries. For example, 33 articles by Saad Fred were cited 2,721 times, and 91 articles from the University of Texas MD Anderson CANC CTR were cited 3,037 times, the most cited author and organization. Peng Xinsheng and Duke UNIV comprise the most active collaborative author and organization, respectively. The most co-cited journal was CANCER RES, with 3,195 citations. Studies of PCa bone metastasis can be divided into four categories: "basic research," "auxiliary diagnosis and treatment," "clinical trial," and "prognosis."
    Conclusion: Our results provide a comprehensive overview of the research priorities and future directions of PCa bone metastasis, which can further accurately guide researchers in diagnosis, treatment, and personalized prevention.

      BACKGROUND: Here, we evaluate the evolution and growth of global neurosurgery publications over time, further focusing on the contribution and impact of authors in low- and middle-income countries (LMICs).METHODS: In this systematic bibliometric analysis, we conducted a two-stage blinded screening process of global neurosurgery publications from five databases from inception through July 2021. Articles involving multi-national/multi-institutional research collaborations, detailing any area of global neurosurgery collaboration, or influencing global neurosurgery practice were included. Statistical hypothesis testing was conducted to analyze trends and hypotheses of LMIC authorship contribution.
    RESULTS: The number of global neurosurgery publications has soared in the last decade. Overall, authors from HIC countries were most commonly from the US (41.1%), Canada (4.0%), and the UK (3.9%), while authors from LMIC countries were most commonly from Uganda (4.2%), Tanzania (2.6%), Cameroon (1.8%), and India (1.8%). Over a quarter (28%) of publications had no LMIC authors, while only 11% had three or more LMIC authors. The proportion of LMIC authors (LMIC-R) was not correlated with the citation rate of individual articles or with the year of publication, and a positive trend emerged when the LMIC-R of top-publishing LMICs were individually examined and compared to year of publication.
    CONCLUSIONS: Despite recent growth, the number of global neurosurgery publications arising from LMICs pales in comparison to those from HICs. Collaborative efforts between certain HICs and LMICs have likely contributed to the observed increase in LMIC author independence over time.

      Background: Spinal cord injury (SCI) has devastating physical and social consequences for patients. Systemic administration of methylprednisolone (MP) at a higher dosage though can reduce neurological deficits following acute SCI. Still, this treatment regimen is controversial, owing to the apparent dose-related side effects and relatively minor improvement in neurological function. Therefore, this study aimed at the bibliometric analysis of published literature related to SCI treatment, which may lead to future research trends.Methods: The literature published relating to SCI and using glucocorticoids for its treatment between 1982 and 2022 was collected and scanned in the Web of Science collection database using the keywords glucocorticoid, dexamethasone, MP, corticosteroids, and SCI, followed by using VOSviewer for bibliometric analysis of these articles.
    Results: A total of 1,848 published articles and 7,448 authors on SCI and glucocorticoid usage were identified. The SCI total link strength accounts for 1,341, and MP for 762 has a strong link to neuroprotection and inflammation. The mean citation count for the top 20 most-cited articles was 682 (range: 358-1,828), where most of these were descriptive studies having focused on clinical features. The Journal of Neurotrauma was the highest-ranked journal with 6,010 citations. A total of 69 articles were published by Michael G Fehlings from the University of Toronto with 6,092 citations. The University of Toronto has published 90-related manuscripts with 7,632 citations. In contrast, 800 articles were published in the United States, with 39,633 citations and total link strength of 5,714. The second-ranked country was China, with 241 published articles and 3,403 citations.
    Conclusions: The research published on applying MP in treating SCI has increased with time. Although the United States has made a significant global contribution to this important field of research, it requires rigorous clinical trials designed to verify the therapeutic role of MP in SCI and its appropriate dosage to find solutions for neurological recovery.

      Over the past decade, neuroscience has been integrated into information systems as a new methodology and perspective to study and solve related problems. Therefore, NeuroIS has emerged as a new cutting-edge research field. This review aimed to identify, summarize, and classify existing NeuroIS publications through knowledge mapping and bibliometric analysis. To effectively understand the development trend of NeuroIS, this study referred to the journal selection index of the Association of Business Schools in 2021 and journals above three stars in the field of information management as the main selection basis. A total of 99 neuroscience papers and their citation data were included from 19 major information systems journals of SCI/SSCI. This study analyzed bibliometric data from 2010 to 2021 to identify the most productive countries, universities, authors, journals, and prolific publications in NeuroIS. To this end, VOSviewer was used to visualize mapping based on co-citation, bibliographic coupling, and co-occurrence. Keywords with strong citation bursts were also identified in this study. This signifies the evolution of this research field and may reveal potential research directions in the near future. In selecting research methods and analysis tools for NeuroIS, content analysis was used to further conclude and summarize the relevant trends. Moreover, a co-citation network analysis was conducted to help understand how the papers, journals, and authors in the field were connected and related, and to identify the seminal or pioneering major literature. For researchers, network maps visualized mainstream research and provided a structural understanding of NeuroIS. The review concludes by discussing potential research topics in this field.

      Anthracyclines constitute the cornerstone of numerous chemotherapy regimens for various cancers. However, the clinical application of anthracyclines is significantly limited to their dose-dependent cardiotoxicity. A comprehensive understanding of the current status of anthracycline-induced cardiotoxicity is necessary for in-depth research and optimal clinical protocols. Bibliometric analysis is widely applied in depicting development trends and tracking frontiers of a specific field. The present study is aimed at revealing the status and trends of anthracycline-induced cardiotoxicity during the past two decades by employing bibliometric software including R-bibliometric, VOSviewer, and CiteSpace. A total of 3504 publications concerning anthracycline-induced cardiotoxicity from 2002 to 2021 were collected from the Web of Science Core Collection database. Results showed significant growth in annual yields from 90 records in 2002 to 304 papers in 2021. The United States was the most productive country with the strongest collaboration worldwide in the field. Charles University in the Czech Republic was the institution that contributed the most papers, while 7 of the top 10 productive institutions were from the United States. The United States Department of Health and Human Services and the National Institutes of Health are the two agencies that provide financial support for more than 50% of sponsored publications. The research categories of included publications mainly belong to Oncology and Cardiac Cardiovascular Systems. The Journal of Clinical Oncology had a comprehensive impact on this research field with the highest IF value and many publications. Simunek Tomas from Charles University contributed the most publications, while Lipshultz Steven E. from the State University of New York possessed the highest H-index. In addition, the future research frontiers of anthracycline-induced cardiotoxicity might include early detection, pharmacogenomics, molecular mechanism, and cardiooncology. The present bibliometric analysis may provide a valuable reference for researchers and practitioners in future research directions.

      An increasing number of studies have shown the effects of time-restricted eating (TRE) on metabolic diseases and cardiovascular diseases associated with obesity. However, no bibliometric analyses were conducted in this field systematically. In our study, we aimed to visualize the publications about TRE to determine the frontiers and hotspots and then provide references and guidance for further studies. Publications about TRE were exported from the Web of Science Core Collection (WOSCC) database. VOSviewer 1.6.16 was adopted to perform the bibliometric analysis. In our study, a total of 414 publications with 298 articles and 116 reviews were included. The publications in this field showed an upward trend from 2016. A total of 2016 authors contributed to this field. The most productive authors were Satchidananda Panda, Krista A Varady and Emily NC Manoogian. All publications were distributed from about 624 organizations from 49 Countries/Regions. The leading institutions were the Salk Institute for Biological Studies, the University of California San Diego and the University of Alabama at Birmingham, and the most productive countries were the United States, the People's Republic of China and Japan. All publications were from 182 journals, and the most productive journals were Nutrients, Frontiers in Nutrition and Cell Metabolism. The first highest cited reference with 991 citations was published in Cell Metabolism, and authored by Satchidananda Panda et al. There were four indicating research directions, and the keywords of the green cluster were time-restricted feeding, metabolism, circadian clock, and circadian rhythm. The keywords of the blue cluster were obesity, health, diet, and food intake. The keywords of the red cluster were intermittent fasting, weight loss, caloric restriction, and time-restricted eating. The keywords of the yellow cluster were insulin resistance, metabolic disease, cardiovascular disease, and caloric intake. The main research hotspots in the TRE field were TRE and circadian rhythm, TRE and obesity, TRE and metabolic disease, and TRE and cardiovascular disease. TRE represents new directions to evaluate the effects of the timing of eating on different diseases, especially obesity, Type 2 diabetes mellitus and cardiovascular disease. Previous studies have generated impressive data on the effects of TRE on metabolic diseases and cardiovascular diseases associated with obesity. More high-quality studies are needed to assess the mechanism and efficacy of TRE in a wide range of populations and diseases.

      Timely dissemination of knowledge is essential and fosters development of knowledge both within academe and the wider society, not least for knowledge that serves practises outside of academia. Here, we compare six disciplines which provide health-related knowledge that serve the health and social services. Most previous research compares the size and impact of the body of publications belonging to each discipline, which ignores the distribution of seniority, productivity, and impact amongst researchers. Instead, we consider the whole population of academics in Sweden employed or active within each discipline, including those who have nil publications. The disciplines form three clusters, where researchers in Public Health and Nursing and Caring science claim about 15 articles per author, Psychology about 10, and Education, Sociology and Social Work less than four. Their numbers of citations follow the same pattern, and are substantially correlated with the number of articles. Tenured or full professors had about 50% more publications and citations per publication than had associate professors. The distributions indicate clear modes at 0, 4, and 16 publications for each cluster, and provide the proportions of researchers within each discipline who have no such publications at all. We discuss the implications of these results for policy, practice, and knowledge quality in the social services and the welfare sector.

      Background: Stem cells (SCs) therapy for intervertebral disc degeneration (IDD) has been studied for nearly 20 years and it is an important part of regenerative medicine and tissue engineering research, as well as a current research hotspot and challenge. Although the volume of literature has shown an annual growth trend, there is no literature available for bibliometric and clinical analysis of the content of multiple databases in this field. Methods: The articles were obtained from the WOSCC, Scopus, Pubmed, and ClinicalTrials on 27 December 2021. Three scientometric software (VOSviewer 1.6.17, CiteSpace 5.8.R.1 and Scimago Graphica) were used to perform bibliometric and knowledge-map analysis. Results: We included 867 articles from WOSCC, 716 articles from Scopus and 6 clinical studies from ClinicalTrials for literature analysis. Our results showed that China was the country with the highest number of publications, with the United States (US) being the leader in terms of international collaborations and the number of citations. Sakai D, Grad S and Hoyland JA had made outstanding contributions for their high productivity and the quality articles. Spine was the most published and most cited journal, in addition to Spine Journal and Biomaterials, which were also more authoritative journals and had received high citations. All of them had received high citations. Keyword co-occurrence studies suggested that the current hotspots were in mechanistic studies, including inflammation, apoptosis, exosome, autophagy, and others. Some studies had also investigated tissue-engineered scaffolds of SCs to better repair degenerated discs. Clinical studies were relatively scarce. Direct injection of Mesenchymal Stem Cells (MSCs) into degenerated discs for the treatment of Degenerative disc disease (DDD) was the current direction of research. Conclusion: This study demonstrates the global research hotspots, trends and clinical use of SCs in the treatment of IDD. It can help scholars to quickly understand the current status and hotspots of research in this field, and also provide some guidance and reference for those who are currently researching in this area.

      PURPOSE: Despite the feminization of the medical profession, the academic world remains largely male-dominated. Several studies conducted in the English-speaking world have shown that women are published less than men. Our goal is to define the evolution of the role of women in five French medical journals.MATERIALS AND METHODS: The articles from five French journals (Revue du Praticien, Bulletin du Cancer, Exercer, Presse Médicale, Cancer/Radiothérapie) published in February between 1983 and 2019 were included. We selected twelve years from that period of time. The analysis was completed using Cochran-Armitage tests with a significance level of<0,05. Among the authors, 4397 were included in total and we were able to determine the gender of 4309 of them.
    RESULTS: The percentage of female authors went from 16% in 1983 to 36.4% in 2019 (p<0.001). This rise is more significant for those specializing in surgery than for those specializing in medicine, with a percentage going from 14% to 38.5% (p<0.001) against 16.8% to 35.4% (p<0.001) respectively. In 2019, women still only represent 30.2% of the last authors, 27.6% of editorial authors and 30.6% of corresponding authors.
    CONCLUSION: Our study underlines a significant increase in the number of female authors and highlights that their position as authors remains on the margins of the most prestigious authorial positions. While we can celebrate this increase, we nevertheless notice that there are fewer female authors than female practitioners.

      Background: The coronavirus disease 2019 (COVID-19) pandemic is disrupting routine medical care of cancer patients, including those who have cancer or are undergoing cancer screening. In this study, breast cancer management during the COVID-19 pandemic (BCMP) is reviewed, and the research trends of BCMP are evaluated by quantitative and qualitative evaluation.Methods: In this study, published studies relating to BCMP from 1 January 2020 to 1 April 2022 were searched from the Web of Science database (WoS). Bibliometric indicators consisted of publications, research hotspots, keywords, authors, journals, institutions, nations, and h-index.
    Results: A total of 182 articles investigating BCMP were searched. The United States of America and the University of Rome Tor Vergata were the nation and the institution with the most publications on BCMP. The first three periodicals with leading published BCMP studies were Breast Cancer Research and Treatment, Breast, and In Vivo. Buonomo OC was the most prolific author in this field, publishing nine articles (9/182, 4.94%). The co-keywords analysis of BCMP suggests that the top hotspots and trends in research are screening, surgery, rehabilitation, emotion, diagnosis, treatment, and vaccine management of breast cancer during the pandemic. The hotspot words were divided into six clusters, namely, screening for breast cancer patients in the pandemic, breast cancer surgery in the pandemic, recovery of breast cancer patients in the pandemic, motion effect of the outbreak on breast cancer patients, diagnosis and treatment of breast cancer patients in the pandemic, and vaccination management for breast cancer patients during a pandemic.
    Conclusion: BCMP has received attention from scholars in many nations over the last 3 years. This study revealed significant contributions to BCMP research by nations, institutions, scholars, and journals.

      OBJECTIVE: To conduct an inductive analysis of neuroimaging studies following the global popularity surrounding the effects of acupuncture.METHODS: The relevant works of literature on acupuncture effects-related neuroimaging studies were retrieved from the web of science core collection database from the date of its establishment to 2022. Bibexcel software was used to extract information, such as article numbers, countries, journals, agencies, funding sources and keywords. The VOSviewer software's co-occurrence and clustering module was used for the co-occurrence and cluster analysis of collaborative networks and high frequency keywords, such as authors, institutions and countries.
    RESULTS: Neuroimaging research on the effects of acupuncture began in the 1960 s and has since received the extensive attention of scholars. China, The United States and South Korea conduct more neuroimaging research on the effects of acupuncture than other countries. Academic journals such as Evidence-Based Complementary and Alternative Medicine, Journal of Alternative and Complementary Medicine, Neural Regeneration Research and Acupuncture in Medicine have published the highest number of acupuncture-related neuroimaging articles. Moreover, cluster analysis differentiates high-frequency keywords into six clusters. Furthermore, the use of the keyword 'density atlas' reveals that neuroimaging research on the effects of acupuncture surrounding pain and neurofunctional rehabilitation is currently the research focus.
    CONCLUSIONS: This bibliometric study identifies six important research hot spots: Static brain functional connectivity analysis of acupuncture analgesic effects, key theories on the scientific problems of acupuncture, acupuncture analgesic effect of the placebo effect, the neuroimaging of acupoint ST-36, the value of acupuncture in regulating the autonomic nerves and acupuncture therapy as complementary medicine.

      Manual dexterity is essential for performing daily life tasks, becoming a primary means of interaction with the physical, social, and cultural environment. In this respect, the Nine Hole Peg Test (NHPT) is considered a gold standard for assessing manual dexterity. Bibliometrics is a discipline that focuses on analyzing publications to describe, evaluate, and predict the status and development trends in certain fields of scientific research. We performed a bibliometric analysis to track research results and identify global trends regarding the use of the NHPT. The bibliographic data were retrieved from the Web of Science database and then analyzed using the Bibliometrix R package, resulting in the retrieval of a total of 615 publications from 1988 to 2021. Among the 263 journals investigated, the most prolific were the Multiple Sclerosis Journal, Clinical Rehabilitation, and Multiple Sclerosis and Related Disorders. North America and Europe were the areas with the highest production of publications, with the United States (n = 104) ranking first in terms of the number of publications, followed by the United Kingdom (n = 62) and Italy (n = 62). The analysis of keywords revealed that there were two main lines of research, with one related to the study of recovery and disability of the upper limbs caused by certain diseases and another related to the study of reliability and validity. Structured information can be useful to understand the research trajectory and the uses of this tool.

      This study aims to identify the evolution, trends and research agenda in city brand research. The methodology used was a science mapping bibliometric and network analysis using both, WoS and Scopus databases, to do a systematic literature review. The results of this analysis resulted in four possible perspectives in the research on city brand: Marketing of city brand, Residents and city brand, Governance of city brand and Economic and social impact of city brand. Like all bibliometric studies, this one has limitations due to its specific methodology, such as the consultation of databases that possibly excluded other studies that could offer a broader panorama, likewise, the analysis network methodology proposed perspectives that they can also be limited and exclusive. This study presents a novelty of the bibliometric analysis tool in the city brand research.

      Introduction and Purpose: Breast reconstruction is an active area of plastic surgery research. Citation analysis allows for quantitative analysis of publications, with more citations presumed to indicate greater influence. We performed citation analysis to evaluate the most cited papers on breast reconstruction between 2000 to 2010 to identify contemporary research trends. Methods: The SCI-EXPANDED database was used to identify the 50 most cited papers. Data points included authorship, publication year, publication journal, study design, level of evidence, number of surgeons/institutions, center of surgery, primary outcome assessed, implant/flap/acellular dermal matrix/fat graft, acellular dermal matrix brand and use with implants/flaps, fat graft use with implants/flaps, unilateral/bilateral, one-/two-stage, immediate/delayed, number of patients/procedures, complications. Descriptive analysis of trends was performed based on results. Results: 20% of papers were published in 2006, 16% in 2007 and 12% in both 2004/2009. 66% were published in Plastic and Reconstructive Surgery. The majority were retrospective or case series, and of Level III or IV evidence. The one Level I study was a prospective multicenter trial. 21 and 7 papers discussed procedures by single/multiple surgeons, respectively. Results from single/multiple centers were discussed in 18 and 6 papers, respectively. 30 papers discussed implant-based reconstruction, 22 papers flap-based (19 microsurgical), 15 papers acellular dermal matrix, and five papers fat grafting. The primary focus in the majority was complications or outcomes. Conclusion: Our analysis demonstrates continually evolving techniques in breast reconstruction. However, there is notable lack of high quality evidence to guide surgical decision-making in the face of increasing surgical options.

      Objectives: Cardiothoracic (CT) surgeons with National Institutes of Health (NIH) R01 funding face a highly competitive renewal process. The factors that contribute to successful grant renewal for CT surgeons remain poorly defined. We hypothesized that renewed basic science grants are associated with high research output and scholarly impact during the preceding award cycle.Methods: Using a database of academic CT surgeons (n = 992) at accredited training institutions in 2018, we identified basic science R01 grants awarded to CT surgeon principal investigators since 1985. Data for each award were obtained from publicly available online sources. Scholarly impact was evaluated using the NIH-validated relative citation ratio (RCR), defined as an article's citation rate divided by that of R01-funded publications in the same field. Continuous data are presented as medians and analyzed using the Mann-Whitney test.
    Results: We identified 102 basic science R01 award cycles, including 33 that were renewed (32.4%). Renewed and nonrenewed awards had a similar start year and funding period. Principal investigators of renewed versus nonrenewed awards were similar in surgical subspecialty, research training, attending experience, academic rank, and previous NIH funding. Renewed awards produced more publications per year over the funding cycle (3.4 vs 1.5; P = .0010) and exhibited a greater median RCR during the funding cycle (0.84 vs 0.66; P = .0183).
    Conclusions: CT surgery basic science R01 grants are associated with high research output and scholarly impact. At the 50th percentile among renewed grants, CT surgeons published 3.4 funded manuscripts per year with a median RCR of 0.84 during the previous award cycle.

      In the last decade, there has been a significant advancement in the area of regional anesthesia (RA). Continuous evaluation of research in any developing field using modern technologies and available software is critical to identify future trends, hot spots, and intellectual dynamics. The current study was designed to bibliometrically evaluate the global research in RA using VOSviewer, MS Excel, and CVS-Scopus bibliographic data (2012-2021). Knowledge structure and intellectual dynamics were analyzed using clustering of keyword co-occurrence. Literature screening in the last decade found 6092 original articles (96.1%) and conference papers (3.9%). The top four countries producing articles were the United States (n = 30.57%), India (7.51), the United Kingdom (7.22%), and Canada (6.06%). A significant positive correlation was found in global publication productivity (R2 = 0.9161). The most productive organizations were Harvard University, the University of Toronto, and the Hospital for Special Surgery - New York. A tremendous collaboration was spotted nationally and internationally, especially in pediatric RA. This comprehensive study, which summarizes and evaluates 6902 original research materials on regional anesthesia, may serve as a resource for anesthesiologists, physicians, researchers, and students.

      In recent years, studies have been conducted to quantify the relationship between microeconomic and macroeconomic development. Macroeconomics is the orientation of microeconomic development. Existing research hopes to quantify the relationship between macroeconomics and micro-firms, rather than just focusing on economic indicators. And some empirical studies try to use the relationship between them to discuss its usefulness for micro-firm decision-making. This article focuses on applying and developing aggregate earnings in connecting microenterprise earnings and macroeconomic development. To achieve this goal, this research did a comprehensive bibliometric analysis on macro-accounting on the two most influential databases, namely, Web of Science and Scopus. It used the information visualization software VOSviewer to draw knowledge maps to sort research lines. We also analyzed the research hotspots of macro-accounting in recent years according to the year scale and combined it with the neural network PSO-LSTM model to predict their future development. It turns out that the research on aggregate earnings related to economic growth has become a research hotspot in recent years. Scopus research and development potential is better than Web of Science in this field.

      Background and objective There is a paucity of information regarding the concordance of traditional metrics across publicly searchable databases and about the correlation between alternative and traditional metrics for neurosurgical authors. In this study, we aimed to assess the congruence between traditional metrics reported across Google Scholar (GS), Scopus (Sc), and ResearchGate (RG). We also aimed to establish the mathematical correlation between traditional metrics and alternative metrics provided by ResearchGate. Methods Author names listed on papers published in the Journal of Neurosurgery (JNS) in 2019 were collated. Traditional metrics [number of publications (NP), number of citations (NC), and author H-indices (AHi)] and alternative metrics (RG score, Research Interest score, etc. from RG and the GS i10-index) were also collected from publicly searchable author profiles. The concordance between the traditional metrics across the three databases was assessed using the intraclass correlation coefficient and Bland-Altman (BA) plots. The mathematical relation between the traditional and alternative metrics was analyzed. Results The AHi showed excellent agreement across the three databases studied. The level of agreement for NP and NC was good at lower median counts. At higher median counts, we found an increase in disagreement, especially for NP. The RG score, number of followers on RG, and Research Interest score independently predicted NC and AHi with a reasonable degree of accuracy. Conclusions A composite author-level matrix with AHi, RG score, Research Interest score, and the number of RG followers could be used to generate an "Impact Matrix" to describe the scholarly and real-world impact of a clinician's work.

      Mountain areas provide essential resources for a significant proportion of the Earth's population. This study presents the development of mountain research between 1900 and 2019 based on peer-reviewed articles in English listed in Web of ScienceTM (WOS). We analyzed the number of publications over time, journals and scientific categories, frequent topics, and geographical distributions based on 40 mountain ranges and authors' countries as well as institutional contributions. From 1900-2019, 195k ±10% mountain research papers were published; over 50% from 2010-2019. While papers were published in more than 1000 different journals, indicating a wide range of disciplines engaged in mountain research, 94% of the papers were assigned to "Science & Technology", only <5% to "Social Sciences" and "Arts & Humanities". The most papers were written by researchers in the USA, followed by China. The number of papers per area or capita showed high variability across the investigated mountain ranges. Thus, geographically and disciplinarily more balanced research activities and better accessibility of knowledge about mountain regions are recommended.

      The last decades have been marked by the introduction of front-of-pack labels (FoPL) as an institutional corrective action against obesity and nutrition-related illnesses. However, FoPL-related policy-making initiatives issued by the European Union evolved over time and led to a diversity of labels with different effects on consumers' decisions. As a result, the extant literature adapted to the regulative scenario over the years and investigated the effects of the labels, creating consensus on some topics while being fragmented on others. Similarly, policy-makers adapted some regulations to the evidence supported by the research. With the aim to systematize the overall structure and evolution of the literature on FoPL, investigate the presence of a consensus on specific topics through a co-citation analysis, and examine the evolution of the consensus and co-citation networks over the years and potential research gaps, we report the results of bibliometric and co-citation analyses and a systematic literature review involving 170 papers and a selection of 49 articles published in the last months, for a total of 219 articles, analysed according to three timespans (Period 1 (1989-2011); Period 2 (2012-2016) and Period 3 (2017-2022)). Our findings highlight the interplay of policy development and FoPL research, the presence of few self-reinforcing and well-established co-citation networks based on validated evidence in the literature and the presence of alternative emerging theories that offer different and valid perspectives overlooked by mainstream co-citation research networks.

      A clearer understanding of research streams and players involved in efforts to address the sustainability of global food and agricultural systems is needed to clarify the current state of scientific knowledge and form collaborations to pursue future research directions. This study presents new insights into this issue through a scientometric process involving a case study of technologies for extending fruit shelf-life. The text mining software was utilized to analyze 3,131 Web of Science-indexed articles published between 2000 and 2020 as a means to glean the conceptual structure of current knowledge and conduct a social network analysis to explore scientific and publication activity. The findings were mapped onto a strategic diagram of research productivity and collaboration between players at the national, organizational, and individual levels. This research's main findings highlight that research on shelf-life technology is in continuous development, and academic institutions from China, Spain, and the U.S. are the core national players in this field. The results provide insights for further investigation to strengthen co-research and technological development programs in other fields. Researchers who are exploring networking opportunities can use the model and process presented as a guideline for identifying emerging and future research trends and formulating strategies.

      Snake envenomation is a severe economic and health concern affecting countries worldwide. Snake venom carries a wide variety of small peptides and proteins with various immunological and pharmacological properties. A few key research areas related to snake venom, including its applications in treating cancer and eradicating antibiotic-resistant bacteria, have been gaining significant attention in recent years. The goal of the current study was to analyze the global profile of literature in snake venom research. This study presents a bibliometric review of snake venom-related research documents indexed in the Scopus database between 1933 and 2022. The overall number of documents published on a global scale was 2999, with an average annual production of 34 documents. Brazil produced the highest number of documents (n = 729), followed by the United States (n = 548), Australia (n = 240), and Costa Rica (n = 235). Since 1963, the number of publications has been steadily increasing globally. At a worldwide level, antivenom, proteomics, and transcriptomics are growing hot issues for research in this field. The current research provides a unique overview of snake venom research at global level from 1933 through 2022, and it may be beneficial in guiding future research.

      Considerable scholarly attention has been directed to the adverse health effects caused by residential segregation. We aimed to visualize the state-of-the-art residential segregation and health research to provide a reference for follow-up studies. Employing the CiteSpace software, we uncovered popular themes, research hotspots, and frontiers based on an analysis of 1211 English-language publications, including articles and reviews retrieved from the Web of Science Core Collection database from 1998 to 2022. The results revealed: (1) The Social Science & Medicine journal has published the most studies. Roland J. Thorpe, Thomas A. LaVeist, Darrell J. Gaskin, David R. Williams, and others are the leading scholars in residential segregation and health research. The University of Michigan, Columbia University, Harvard University, the Johns Hopkins School of Public Health, and the University of North Carolina play the most important role in current research. The U.S. is the main publishing country with significant academic influence. (2) Structural racism, COVID-19, mortality, multilevel modelling, and environmental justice are the top five topic clusters. (3) The research frontier of residential segregation and health has significantly shifted from focusing on community, poverty, infant mortality, and social class to residential environmental exposure, structural racism, and health care. We recommend strengthening comparative research on the health-related effects of residential segregation on minority groups in different socio-economic and cultural contexts.

      Polymeric materials are used for personal protective equipment (PPE), which is mandatory for clinicians to use when handling coronavirus disease 2019 (COVID-19) patients. The development of diagnostic tools and vaccines for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is also dependent on polymer technology. This current report aims to provide readers with the trend of polymer research regarding the COVID-19 pandemic, by employing bibliometric analysis. A literature search on the Scopus database (31 January 2022) was carried out using predetermined terms. Using Scopus database features, the publications were filtered based on the year of publication (2020-2022), types of articles (original research and review), and language (English). The metadata were extracted in a CSV (.csv) file, to be later used in VOSviewer software. The data were presented in a table, graph, and network visualization. As many as 512 publications were included, consisting of 66.4% original research articles and 33.6% review articles. Most of the publications were written by authors whose affiliation was in the United States (n = 118, 23%) and covering the Materials Science subject area (n = 142, 27.7%). The Ministry of Education of China was the most productive organization, publishing 11 articles. The National Science Foundation of China was the top funding source, supporting 45 publications. Heinz C. Schröder was the most prolific author, publishing nine articles. Science of the Total Environment was the leading journal publishing the included studies. The trend of polymer technology related to COVID-19 mostly covers PPE and waste-management themes. The use of polymer technology as a delivery system for the anti-SARS-CoV-2 and COVID-19 vaccine is also among the frequently researched areas. We encourage more research in the field of polymer technology be carried out, to overcome the global pandemic.

      The sheer volume of research publications on physical activity, mental health, and wellbeing is overwhelming. The aim of this study was to perform a broad-ranging scientometric analysis to evaluate key themes and trends over the past decades, informing future lines of research. We searched the Web of Science Core Collection from inception until December 7, 2021, using the appropriate search terms such as "physical activity" or "mental health," with no limitation of language or time. Eligible studies were articles, reviews, editorial material, and proceeding papers. We retrieved 55,353 documents published between 1905 and 2021. The annual scientific production is exponential with a mean annual growth rate of 6.8% since 1989. The 1988-2021 co-cited reference network identified 50 distinct clusters that presented significant modularity and silhouette scores indicating highly credible clusters (Q = 0.848, S = 0.939). This network identified 6 major research trends on physical activity, namely cardiovascular diseases, somatic disorders, cognitive decline/dementia, mental illness, athletes' performance, related health issues, and eating disorders, and the COVID-19 pandemic. A focus on the latest research trends found that greenness/urbanicity (2014), concussion/chronic traumatic encephalopathy (2015), and COVID-19 (2019) were the most active clusters of research. The USA research network was the most central, and the Chinese research network, although important in size, was relatively isolated. Our results strengthen and expand the central role of physical activity in public health, calling for the systematic involvement of physical activity professionals as stakeholders in public health decision-making process.

      PURPOSE: Gender equity is a key performance metric in research, including systematic reviews, and is increasingly noted in publications. We performed this study to assess gender parity in scientific authorship of systematic reviews published in the urological literature.METHODS: We identified all published systematic reviews addressing questions of therapy/prevention in 5 major urological journals (Journal of Urology, European Urology, Urology, BJU International and World Journal of Urology) from 1998 to 2021. We determined gender of first, second, corresponding and any author as a binary variable (woman or man) using a predefined algorithm.
    RESULTS: We included 523 systematic reviews. The main journal contributors were European Urology (32.6%), BJU International (22.0%) and Journal of Urology (19.5%). Slightly more than half (51.8%) of reviews included at least one woman co-author, 37.5% did not and in 10.7% it was unclear. First, second and corresponding authors were women in 13.7%, 12.4% and 4.7% respectively and the median number of women contributors was 1 (interquartile range: 0-2). Women first authorship for the time period 1998-2012 was 13.0% (p=0.139), and senior authorship was 5.0% (p=0.270). In 2013-2016 it was 11.0% and 4.1%, and in 2017-2021 it increased somewhat to 16.5% and 5.1% (p=0.270), respectively.
    CONCLUSIONS: The number of women involved in systematic reviews is low and has not improved over time. Since scientific authorship is important for academic advancement, this finding may contribute to the underrepresentation of women in academic leadership positions. Efforts to improve gender diversity in urology should include more collaboration across genders.

      Sub-Saharan Africa has the highest incidence of cervical cancer globally. However, compared to developed countries, the region has lower uptake of cervical cancer screening. Research contribution and progress in the field of cervical cancer in the region has not been well investigated. This bibliometric review aimed to address this information gap by examining changes in research volume and type over a 20 year time frame. Medline, Embase, PsycINFO, CINAHL, and Cochrane Library were searched to identify peer-reviewed publications about cervical cancer screening in sub-Saharan Africa. Changes (from 2001 to 2020) in the (i) total publications, (ii) number and proportion of data-based publications relative to non-data-based publications, and descriptive relative to intervention publications, and (iii) the number and proportion of publications meeting the EPOC design criteria relative to those not meeting the EPOC design criteria were assessed using a generalised linear Poisson model, a generalised binomial model and the Pearson Chi-squared test respectively. A two-year increase in time was associated with an estimated 32 % increase in the total number of publications. While no measurement studies were recorded, the bulk of data-based publications (89 %) were descriptive studies. Relative to descriptive publications, a 1 % increase in the proportion of intervention publications was observed over time. Only a small proportion (28 %) of intervention studies met the EPOC design criteria. Our findings suggest that researchers and funders in the region should invest more effort and money in measurement and rigorous intervention research to inform outcome measures and cervical cancer screening policy and practice, respectively.

      Biodegradable materials are appropriate for the environment and are gaining immense attention worldwide. The mechanical properties (such as elongation at break, density, and failure strain) of some natural fibers (such as Coir, Hemp, Jute, Ramie, and Sisal) are comparable with those of some synthetic fibers (such as E glass, aramid, or Kevlar). However, the toughness of coconut fibers is comparatively more than other natural fibers. Numerous studies suggest coconut fibers perform better to improve the concrete mechanical properties. However, the knowledge is dispersed, making it difficult for anyone to evaluate the compatibility of coconut fibers in concrete. This study aims to perform a scientometric review of coconut fiber applications in cementitious concrete to discover the various aspects of the literature. The typical conventional review studies are somehow limited in terms of their capacity for linking different literature elements entirely and precisely. Science mapping, co-occurrence, and co-citation are among a few primary challenging points in research at advanced levels. The highly innovative authors/researchers famous for citations, the sources having the highest number of articles, domains that are actively involved, and co-occurrences of keywords in the research on coconut-fiber-reinforced cementitious concrete are explored during the analysis. The bibliometric database with 235 published research studies, which are taken from the Scopus dataset, are analyzed using the VOSviewer application. This research will assist researchers in the development of joint ventures in addition to sharing novel approaches and ideas with the help of a statistical and graphical description of researchers and countries/regions that are contributing. In addition, the applicability of coconut fiber in concrete is explored for mechanical properties considering the literature, and this will benefit new researchers for its use in concrete.

      BACKGROUND: Despite the "fourth threat" of administrative demands, department chairs of surgery are expected to continue being a "triple threat": productive in research, outstanding in teaching, and exemplary in practice. Increased demands despite limited time are the catch-22 of promotion. This study investigated the influence of becoming department chair on scholarly vigor.METHODS: The surgeons listed in the Society of Surgical Chairs Membership Directory website (n = 118) were included in this study. Three measures were compared during the pre- and post-promotion phases: (1) research productivity (annual publications); (2) authorship position in publications (first-authorship, co-authorship, and senior-authorship); and (3) scholarly impact (m-index and National Institute of Health funding).
    RESULTS: The median [interquartile range] number of publications per year increased post-promotion versus pre-promotion (7.64 [3.81-14.15] vs 4.12 [2.08-7.03], P < .0005). The median [interquartile range] number of first-authorship publications per year decreased (0.50 [0.00-1.00] vs 0.64 [0.32-1.22], P < .05), whereas the median [interquartile range] number of co-authorship (4.23 [1.98-9.70] vs 2.02 [1.02-3.95], P < .0005) and senior-authorship (1.87 [0.99-4.03] vs 1.00 [0.36-2.24], P < .0005) publications per year increased post-promotion. The mean ± standard deviation m-index increased post-promotion (1.67 ± 1.19 vs 1.23 ± 0.83, P < .01). The mean ± standard deviation annual National Institute of Health grant funding amount of 48% (n = 57) of the department chairs increased post-promotion ($365,000 ± $899,000 vs $98,000 ± $143,000 pre-promotion, P < .05).
    CONCLUSION: The fourth threat of administrative demands is not a threat to the triple threat. This study showed the department chairs' continued scholarly vigor after promotion, providing insight into their tenacity, resilience, and dedication.

      Citation data and journal impact factors are important components of faculty dossiers and figure prominently in both promotion decisions and assessments of a researcher's broader societal impact. Although these metrics play a large role in high-stakes decisions, the evidence is mixed about whether they are strongly correlated with indicators of research quality. We use data from a large-scale dataset comprising 45 144 journal articles with 667 208 statistical tests and data from 190 replication attempts to assess whether citation counts and impact factors predict three indicators of research quality: (i) the accuracy of statistical reporting, (ii) the evidential value of the reported data and (iii) the replicability of a given experimental result. Both citation counts and impact factors were weak and inconsistent predictors of research quality, so defined, and sometimes negatively related to quality. Our findings raise the possibility that citation data and impact factors may be of limited utility in evaluating scientists and their research. We discuss the implications of these findings in light of current incentive structures and discuss alternative approaches to evaluating research.

      The habenula (Hb) is a small structure of the posterior diencephalon that is highly conserved across vertebrates but nonetheless has attracted relatively little research attention until the past two decades. The resurgent interest is motivated by neurobehavioral studies demonstrating critical functions in a broad spectrum of motivational and cognitive processes, including functions relevant to psychiatric diseases. The Hb is widely conceived as an "anti-reward" center that acts by regulating brain monoaminergic systems. However, there is still no general conceptual framework for habenula research, and no study has focused on uncovering potentially significant but overlooked topics that may advance our understanding of physiological functions or suggest potential clinical applications of Hb-targeted interventions. Using science mapping tools, we quantitatively and qualitatively analyzed the relevant publications retrieved from the Web of Science Core Collection (WoSCC) database from 2002 to 2021. Herein we present an overview of habenula-related publications, reveal primary research trends, and prioritize some key research fronts by complementary bibliometric analysis. High-priority research fronts include Ventral Pallidum, Nucleus Accumbens, Nicotine and MHb, GLT-1, Zebrafish, and GCaMP, Ketamine, Deep Brain Stimulation, and GPR139. The high intrinsic heterogeneity of the Hb, extensive connectivity with both hindbrain and forebrain structures, and emerging associations with all three dimensions of mental disorders (internalizing, externalizing, and psychosis) suggest that the Hb may be the neuronal substrate for a common psychopathology factor shared by all mental illnesses termed the p factor. A future challenge is to explore the therapeutic potential of habenular modulation at circuit, cellular, and molecular levels.

      Motor learning enables preschoolers and children to acquire fundamental skills that are critical to their development. The current study sought to conduct a bibliometric and visualization analysis to provide a comprehensive overview of motor-learning progress in preschoolers and children over the previous 15 years. The number of studies is constantly growing, with the United States and Australia, as well as other productive institutions and authors, at the leading edge. The dominant disciplines were Neurosciences and Neurology, Psychology, Rehabilitation, and Sport Sciences. The journals Developmental Medicine & Child Neurology, Human Movement Science, Physical Therapy, Neuropsychology, Journal of Motor Behavior, and Journal of Experimental Child Psychology have been the most productive and influential in this regard. The most common co-citations for clinical symptoms were for cerebral palsy, developmental coordination disorder, and autism. Research has focused on language impairment (speech disorders, explicit learning, and instructor-control feedback), as well as effective intervention strategies. Advances in brain mechanisms and diagnostic indicators, as well as new intervention and rehabilitation technologies (virtual reality, transcranial magnetic stimulation, and transcranial direct current stimulation), have shifted research frontiers and progress. The cognitive process is critical in intervention, rehabilitation, and new technology implementation and should not be overlooked. Overall, our broad overview identifies three major areas: brain mechanism research, clinical practice (intervention and rehabilitation), and new technology application.

      This study was designed to evaluate the emerging trends of research on mRNA vaccines. Altogether 3056 research articles related to mRNA vaccines published since 2010 were retrieved from the Web of Science database, based on which a co-citation analysis was conducted using CiteSpace. A total of 12 clusters were derived, all of which were classified into three periods according to the content and publication time of articles: (1) The preliminary exploratory period before early 2010s, when the potential of mRNA to induce immune response was evaluated; (2) the growing up period from early 2010s to 2019, when the stability and immunogenicity of mRNA vaccines were improved and the clinical development of products were pushed forward; (3) the rapid maturity period after the outbreak of COVID-19, when two products for COVID-19 were authorized for the first time. The approval of COVID-19 vaccines is an encouraging start, while the enormous potential of mRNA vaccines remains to be explored. Future research on mRNA-based infectious disease vaccines will focus on further optimizing mRNA modification and delivery, solving problems of the approved vaccines in real world, investigating mRNA vaccines for other infectious indications, and developing self-amplifying or thermostable vaccines. Future research on mRNA-based therapeutic cancer vaccines will focus on screening proper neoantigens, enhancing the delivery of mRNA into antigen-presenting cells and overcoming suppressive tumor microenvironment.

      The pandemic led to a significant change in the clinical routine of many orthopaedic surgeons. To observe the impact of the pandemic on scientific output all studies published in the fields of orthopaedics listed in the Web of Science databases were analysed regarding the scientific merit of the years 2019, 2020, and 2021. Subsequently, correlation analyses were performed with parameters of regional pandemic situation (obtained from WHO) and economic strength (obtained from the World Bank). The investigations revealed that the Covid-19 pandemic led to a decrease in the annual publication rate for the first time in 20 years (2020 to 2021: -5.69%). There were regional differences in the publication rate, which correlated significantly with the respective Covid-19 case count (r = -.77, p < 0.01), associated death count (r = -.63, p < 0.01), and the gross domestic product per capita (r = -.40, p < 0.01) but not with the number of vaccinations (r = .09, p = 0.30). Furthermore, there was a drastic decrease in funding from private agencies (relative share: 2019: 36.43%, 2020: 22.66%, 2021: 19.22%), and a balanced decrease in publication output for research areas of acute and elective patient care. The Covid-19 pandemic resulted in a decline in orthopaedic annual publication rates for the first time in 20 years. This reduction was subject to marked regional differences and correlated directly with the pandemic load and was associated with decreased research funding from the private sector.

      Purpose: Determine the educational background, research publications/presentations experience, and rates of research publication and presentation inaccuracies in applications to a Canadian diagnostic imaging residency program. Method: The education and publication/presentation sections of the Canadian Resident Matching Service form for all applicants to the University of Saskatchewan diagnostic imaging residency program from 2019-20 and 2020-21 were reviewed. Number of advanced degrees (Master's/PhDs), publications, and presentations were recorded. Accuracy of publications listed was confirmed via PubMed-MEDLINE, journal's website, or internet searching. Accuracy of presentations was confirmed via society and residency program websites. Inaccuracies of non-authorship, incorrect authorship order/status (self-promotion or demotion), and nonexistence of article/presentation from a verifiable source were recorded. Result: There were a total of 106 applicants. Thirty (28%) had advanced degrees. There were 230 publications from 61 applicants with inaccuracies in only 5 (2%) of the publications (2 self-promotion, 3 self-demotion). For the 77 publications listed as pending, 25 (31%) were published within 6 months of applications deadlines with 1 non-authorship, 1 self-promotion, and 1 self-demotion. For scientific presentations, there were 467 listed presentations by 91 applicants. Two hundred and twenty-one presentations were from verifiable sources with inaccuracies in 28 (13%) of presentations (9 self-promotion, 9 self-demotion, 1 non-authorship, and 9 non-existence). Conclusion: Despite some uncertainty with scientific articles reported as pending and scientific presentations, radiology residency applicants are accurately representing their published articles with a negligible number of misrepresentations. Canadian radiology residency programs should regard the publication profiles of the applicants with a high level of confidence.

      Telemedicine is becoming a standard method of consultation, and the COVID-19 pandemic has increased its need. Telemedicine is suitable for non-communicable diseases (NCDs) in the pediatric population, as these are chronic conditions that affect many children worldwide. The aim of this study was to analyze the bibliometric parameters of publications on the use of telemedicine for the most common NCDs in children before and after the COVID-19 pandemic. Following the electronic search, 585 records were selected. "Metabolic diseases" was the most frequent topic before and after the pandemic, accounting for 34.76% in 2017-2019 and 33.97% in 2020-2022. The average IF of the journals from which records were retrieved was 5.46 ± 4.62 before and 4.58 ± 2.82 after the pandemic, with no significant variation. The number of citations per reference averaged 14.71 ± 17.16 in 2017-2019 (95% CI: 12.07; 17.36) and 5.54 ± 13.71 in 2020-2022 (95% CI: 4.23; 6.86). Asthma, metabolic diseases, and neurodevelopmental disorders were the most explored topics. A relevant finding concerns the increasing number of observational studies after the pandemic, with a reduction of the interventional studies. The latter type of study should be recommended as it can increase the evaluation of new strategies for the management of NCDs.

      Across the world, many infants, children, adults, and elderly people are reported with many types of disorders and disabilities that damage, delay, or impede typical language development and/or use. Speech-language pathologists and other relevant clinicians are responsible for diagnosing, assessing, and rehabilitating these conditions. In nearly all types of disorders or disabilities that affect language, clinical linguistics plays a significant role in their study, diagnosis, and evaluation. This study provides a thorough analysis of the field of clinical linguistics. Data from Scopus, WOS, and Lens were used between 1981 and 2022. The documents included in the analysis were 1685, 1628, and 2677 articles published between 1981 and 2022 in clinical linguistics in Scopus, WOS, and Lens, respectively. For the purpose of assessing the development and impacts of the field of clinical linguistics, we used eight bibliometric and eight scientometric indicators. As part of the study, the results summarized the top contributors to clinical linguistics in terms of production size by year, country, university/research centre, journal, publisher, and author. The impact of the examined evidence on clinical linguistics was visualized and tabulated in the form of visual networks, citation counts, burst, cooccurrence, centrality, and sigma factors that are helpful in identifying the main influencers in clinical linguistics. A few examples of clinical linguistics patterns that are being explored extensively by researchers include cleft palate speech with model theories, visual feedback, motor speech disorders with instrumental analysis, acoustic analysis to understand conversational breakdown, nonlinear phonological theory, aphasic conversation in atypical interaction, and diagnostic markers in functional segments. There are also phonological disorders, William Syndrome, and the use of ultrasound, which may be considered potential clusters of clinical linguistics. A key contribution of this paper is highlighting the importance of clinical linguistics as well as its integration with linguistics, speech-language pathology, neurolinguistics, psycholinguistics, neuroscience, cognitive sciences, psychology, and psychometrics.

      As global change continues to intensify, the mode and rate of nitrogen input from the atmosphere to grassland ecosystems had changed dramatically. Firstly, we conducted a systematic analysis of the literature on the topic of nitrogen deposition impacts over the past 30 years using a bibliometric analysis. A systematic review of the global research status, publication patterns, research hotspots and important literature. We found a large number of publications in the Chinese region, and mainly focuses on the field of microorganisms. Secondly, we used a meta-analysis to focus on microbial changes using the Chinese grassland ecosystem as an example. The results show that the research on nitrogen deposition in grassland ecosystems shows an exponential development trend, and the authors and research institutions of the publications are mainly concentrated in China, North America, and Western Europe. The keyword clustering results showed 11 important themes labeled climate change, elevated CO2, species richness and diversity, etc. in these studies. The burst keyword analysis indicated that temperature sensitivity, microbial communities, etc. are the key research directions. The results of the meta-analysis found that nitrogen addition decreased soil microbial diversity, and different ecosystems may respond differently. Treatment time, nitrogen addition rate, external environmental conditions, and pH had major effects on microbial alpha diversity and biomass. The loss of microbial diversity and the reduction of biomass with nitrogen fertilizer addition will alter ecosystem functioning, with dramatic impacts on global climate change. The results of the study will help researchers to further understand the subject and have a deep understanding of research hotspots, which are of great value to future scientific research.

      OBJECTIVE: COVID-19 has not only impacted healthcare systems directly via hospitalizations and resource utilization, but also indirectly via adaptations in healthcare practice, such as the evolution of the academic environment and the rise of telemedicine and virtual education. This void in clinical responsibilities has been filled with academic productivity in various fields. In this study the authors investigate the influence of COVID-19 on the academic focus within pediatric neurosurgery.METHODS: All data were obtained from the Journal of Neurosurgery: Pediatrics (JNS Peds). The number of submissions for each month from January 2017 to December 2021 was collected. Data including number of publications, publication level of evidence (LOE), and COVID-19-related articles were collected and verified. Each publication was categorized by manuscript and LOE according to adaptations from the Canadian Task Force on Periodic Health Examination. Publication groups were categorized as pre-COVID-19 (January 2017-February 2020), peri-COVID-19 (March 2020-July 2020), and post-COVID-19 (August 2020-December 2021). Statistical analysis was performed to compare pre-COVID-19, peri-COVID-19, and post-COVID-19 academic volume and quality.
    RESULTS: During the study time period, a total of 3116 submissions and 997 publications were identified for JNS Peds. Only 2 articles specifically related to COVID-19 and its impact on pediatric neurosurgery were identified, both published in 2021. When analyzing submission volume, a statistically significant increase was seen during the shutdown relative to pre-COVID-19 and post-shutdown time periods, and a significant decrease was seen post-shutdown relative to pre-COVID-19. LOE changed significantly as well. When comparing pre-COVID-19 versus post-COVID-19 articles, a statistically significant increase was identified only in level 4 publications. When analyzing pre-COVID-19 versus post-COVID-19 (2020) and post-COVID-19 (2021), a statistically significant decrease in level 3 and increases in levels 4 and 5 were identified during post-COVID-19 (2020), with a rebound increase in level 3 and a decrease in level 5 during post-COVID-19 (2021).
    CONCLUSIONS: There was a significant increase in manuscript submission during the initial pandemic period. However, there was no change during subsequent spikes in COVID-19-related hospitalizations. Coincident with the initial surge in academic productivity, despite steady publication volume, was an inverse decline in quality as assessed by LOE.

      Objective: This study's objective was to evaluate the scholastic and career effects of receiving either the American Association for Thoracic Surgery (AATS) Foundation research scholarship or surgical investigator program.Methods: AATS annual reports and recipient listings were used to generate the awardees. MEDLINE and SCOPUS were used to assess publications, citations, and H-Index for awardees. The National Institutes of Health (NIH) RePorter was used to collate NIH grant awarding to awardees. Publicly available institutional profiles were used to assess promotion status and leadership positions.
    Results: Awardees of the research scholarship had a median of 4733 citations and a median H-Index of 33. The surgical investigator program recipients had a median of 1346 citations with a median H-Index of 17. Across both funding mechanisms, 45% secured subsequent NIH funding. Most awardees received an academic promotion, with 62% of the research scholarship awardees promoted to full professor and 37% of the surgical investigator program to associate professor. Approximately half (48%) of all awardees hold leadership positions, with most being a clinical director or division chief.
    Conclusions: Receiving the AATS Foundation research scholarship or surgical investigator program positions early-career cardiothoracic surgeons for a promising future in academic surgery.

      Analysis of citation networks in biomedical research has indicated that belief in a specific scientific claim can gain unfounded authority through citation bias (systematic ignoring of papers that contain content conflicting with a claim), amplification (citation to papers that don't contain primary data), and invention (citing content but claiming it has a different meaning). There is no a priori reason to expect that citation distortion is limited to particular fields of science. This Pespective presents a case study of literature on maximum iron loading of the ferritin protein to illustrate that the field of metallomics is no exception to the rule that citation distortion is a widespread phenomenon.

    National Dental PBRN Collaborative Group
      Introduction: Following inception in 2005 as a multiregional practice-based research network (PBRN), the "National Dental PBRN" expanded nationwide in 2012, and in 2019 implemented additional organizational changes. The objectives are to: (1) describe the new structure and function of the network; and (2) quantify its scientific productivity since 2005.Methods: A national Administrative and Resource Center is based in Alabama; regional and specialty nodes are based in Alabama, Florida, Illinois, Minnesota, Oregon, New York, and Texas. A Network Coordinating Center is based in Oregon. Studies are funded via investigator-initiated grants. Scientific productivity is assessed using specific metrics, including the Relative Citation Ratio.
    Results: To date, 58 studies have been completed or are in data collection or development. These studies have investigated a broad range of topics using a wide variety of study designs. Of the studies that have completed enrollment, 70,665 patients were enrolled, as were 19,827 practitioners (some participated in multiple studies), plus electronic records for 790,493 patients in two data-only studies. To date, these studies have led to 193 peer-reviewed scientific publications in 62 different journals. The mean (1.40) Relative Citation Ratio of Network publications connotes a greater-than-average influence in their fields.
    Conclusions: These metrics demonstrate that the PBRN research context can successfully engage practitioners and patients from diverse settings nationally with a high and sustained level of scientific productivity. This infrastructure has enabled clinical scientists in oral health and nonoral health topics and provided additional recruitment venues outside of the typical academic health center research context.

      Malondialdehyde (MDA) is a product of lipid peroxidation that is often determined in abiotic stress-related phytoremediation research. This study assessed (July 14, 2022) the frequency of eight nomenclatural forms of MDA between 2001 and 2021 using three major databases (PubMed, Scopus, and Web of Science (WoS9). The most common form (75,060, 57,874, and 65,663 times in PubMed, Scopus, and WoS, respectively) of MDA was "malondialdehyde", followed by "malonaldehyde" (68,240, 3815, and 2337 times in these three databases, respectively). According to WoS, the journals that used "malondialdehyde" and "malonaldehyde" most frequently were Environmental Science and Pollution Research (Springer-Nature) (587 times) and The Journal of Chemical Physics (AIP Publishing) (57 times). Other less-frequent forms were: malonyldialdehyde, malonic dialdehyde, malon-dialdehyde, malone dialdehyde, malonic aldehyde, and malonodialdehyde. We recommend that the editors of journals that publish papers with themes that are closely associated with plant stress specify in their instructions for authors their journal's preferable nomenclatural form of MDA. The plant abiotic stress community, including phytoremediation specialists, need to debate this topic with the objective of seeking a standardized nomenclatural form of MDA, which would help to fortify the integrity of searches in major databases by allowing all relevant literature to be accurately identified. Novelty statementMalondialdehyde (MDA), a product of lipid peroxidation that is often determined in stress-related phytoremediation research, has various forms to its name. These nomenclatural variations were assessed in PubMed-, Scopus-, and Web of Science-indexed literature. This is the first study to detect, report, quantify and debate these forms of MDA.

      OBJECTIVES: This paper aimed to identify the technology frontiers of artificial intelligence-assisted pathology based on patent citation network.METHODS: Patents related to artificial intelligence-assisted pathology were searched and collected from the Derwent Innovation Index (DII), which were imported into Derwent Data Analyzer (DDA, Clarivate Derwent, New York, NY, USA) for authority control, and imported into the freely available computer program Ucinet 6 for drawing the patent citation network. The patent citation network according to the citation relationship could describe the technology development context in the field of artificial intelligence-assisted pathology. The patent citations were extracted from the collected patent data, selected highly cited patents to form a co-occurrence matrix, and built a patent citation network based on the co-occurrence matrix in each period. Text clustering is an unsupervised learning method, an important method in text mining, where similar documents are grouped into clusters. The similarity between documents are determined by calculating the distance between them, and the two documents with the closest distance are combined. The method of text clustering was used to identify the technology frontiers based on the patent citation network, which was according to co-word analysis of the title and abstract of the patents in this field.
    RESULTS: 1704 patents were obtained in the field of artificial intelligence-assisted pathology, which had been currently undergoing three stages, namely the budding period (1992-2000), the development period (2001-2015), and the rapid growth period (2016-2021). There were two technology frontiers in the budding period (1992-2000), namely systems and methods for image data processing in computerized tomography (CT), and immunohistochemistry (IHC), five technology frontiers in the development period (2001-2015), namely spectral analysis methods of biomacromolecules, pathological information system, diagnostic biomarkers, molecular pathology diagnosis, and pathological diagnosis antibody, and six technology frontiers in the rapid growth period (2016-2021), namely digital pathology (DP), deep learning (DL) algorithms-convolutional neural networks (CNN), disease prediction models, computational pathology, pathological image analysis method, and intelligent pathological system.
    CONCLUSIONS: Artificial intelligence-assisted pathology was currently in a rapid development period, and computational pathology, DL and other technologies in this period all involved the study of algorithms. Future research hotspots in this field would focus on algorithm improvement and intelligent diagnosis in order to realize the precise diagnosis. The results of this study presented an overview of the characteristics of research status and development trends in the field of artificial intelligence-assisted pathology, which could help readers broaden innovative ideas and discover new technological opportunities, and also served as important indicators for government policymaking.

      AIM: to describe the publication rates of the theses in preventive and community medicine supported at the medical university of Tunis from 2012 to 2017 and to determine factors affecting their publication in scientific journals.METHODS: descriptive and retrospective study on defended theses in preventive and community medicine listed in the library of the medical university of Tunis. We considered as published thesis, works published as an article or as a published abstract. A multivariate analysis was performed to study the determinants of thesis publication.
    RESULTS: The study concerned 84 preventive and community medicine theses. Thirty theses were published (35.7%), including 19 theses (63.3%) as research papers, in scientific journals. Almost two-thirds (67.8%) of publications were in French. The publications were mainly submitted (22/56) in two journals: « Revue d'Épidémiologie et de Santé Publique » and « La Tunisie Médicale ». The student's name was mentioned in 63.4% of published works. The determinants of publication in multivariate analysis were the the status of the thesard (p=0.001), the degree of the supervisor (p=0.038), and the formulation of recommendations (p=0.005).
    CONCLUSION: The proportion of publications from preventive and community medicine theses was relatively modest. This is why we must encourage more doctoral students and supervisors to participate in educational seminars on article writing, in order to enrich scientific production by improving the writing quality of their theses.

      Objectives: The objective of this scoping review was to summarize and provide a visual overview of the present-day knowledge on ecological determinants of eating behavior in community-dwelling elderly persons in relation with nutrition communication, considering the evolution of the field. The second objective was to integrate results in recommendations for the development of nutrition communication strategies. Methods: A literature review was performed on Medline, PubMed and Google Scholar, according with the PRISMA protocol for scoping reviews. An a-priori analysis was executed by categorizing determinants from the literature according with the different levels represented in the ecological framework and an a-posteriori analysis by using VosViewer for a chronological bibliometric mapping analysis. Results: Of 4029 articles retrieved, 77 were selected for analysis. Initial publications focused more on individual determinants of eating behavior. Over time, there was a shift towards a holistic view of eating behavior considering the "food environment", including social networks, physical settings and public policy. Conclusion: Beyond the individual, all ecological levels are relevant when targeting eating behavior in the elderly. Nutrition communication strategies should be structured considering these influences.

      Diversity is the fuel of innovation. Global diversity-geographical or international diversification-is indispensable for developing a true psychological science of human beings but remains poorly understood. We surveyed 68 top psychology journals in 10 subdisciplines and examined the global diversity of authors, editors (i.e., members of academic editorial teams), and journal ownership. Results show that (a) the global diversity of authorship, editorship, and ownership is low in top psychology journals, with the United States boasting outsized influences; (b) disparity intensifies along the hierarchy of authors, editors, and journal ownership and substantially differs between subdisciplines and journal types; (c) removing the United States markedly increases global diversity and eliminates differences in diversity between subdisciplines and between authorship and editorship; and (d) more authors and editors are from the journal's home country (vs. a foreign journal) and from the editor-in-chief's home country (vs. a journal with a foreign editor-in-chief), and the home-country biases are most pronounced in the United States-journals from the United States or with U.S. editors-in-chief have the lowest global diversity in authorship and editorship. These results provide substantial novel insights into the global diversity of psychology journals, with implications for a new diversity policy to stimulate the generation of variety and, by extension, innovation.
