       Objectives: The aim of this study was to perform a bibliometric analysis of publications related to perinatal palliative care to identify scientific output and research trends at a global level.
    Methods: The Web of Science Core Collection database was searched to retrieve publications focusing on perinatal palliative care published between 2001 and 2020. All retrieved publications were identified by title and abstract for their relevance to perinatal palliative care. These eligible publications were extracted from the following data: title, abstract, year, keywords, author, organization, journal and cited literature. VOSviewer software was used to conduct bibliographic coupling, coauthorship, and cooccurrence analyses and to detect publication trends in perinatal palliative care research.
    Results: A total of 114 publications concerning perinatal palliative care were included. The annual number of publications has increased dramatically in recent years. The United States has made the largest contribution to this field with the majority of publications (68, 59.6%) and citations (1,091, 70.5%) and with close collaborations with researchers in Canada, Portugal and Australia. Wool C and her institution, York College of Pennsylvania, are the respectively, most prolific author and institution in this field, publishing 18 papers (15.8%). Journal of Palliative Medicine is the leading and main journal in this field. According to the cooccurrence network analysis, five main research topics were identified: the candidates for PPC, service models and forms, framework components, parental perspectives and satisfaction, and challenges and needs of health care providers.
    Conclusion: The findings of this bibliometric study illustrate the current state and global trends of perinatal palliative care for the past two decades, which will help researchers determine areas of research focus and explore new directions for future research in this field.

       BACKGROUND:  Recent years have seen an increase in the number of studies of the sublobar resection approach in non-small cell lung cancer (NSCLC) surgery. The purpose of this bibliometric analysis is to assess the significance and impact of articles comparing sublobar resection and lobectomy in NSCLC surgery.
    MATERIAL AND METHODS:  The Web of Science database was searched to identify studies comparing sublobar resection and lobectomy in NSCLC surgery published between 2005 and 2020 (accessed: September 11, 2020). The 50 most cited articles were analyzed by years, countries, authors, authors' affiliations, journals, journals' addresses, and impact factors.
    RESULTS:  The bibliometric analysis revealed that the most cited article had 443 citations, while the total number of citations of all articles was 2,820. The mean number of citations, in turn, was 56.4 ± 75.62 (1-443) times. The highest number of publications over the past 15 years was in 2016, with eight articles. The Annals of Thoracic Surgery (n = 10; 20%) had the highest number of publications on the list. The articles included in the present study were mostly (n = 35, 70%) published in U.S. journals. While multiple subject matters and analyses were presented by many studies, survival was the topic of greatest interest, with 37 (74%) studies.
    CONCLUSION:  This study revealed that interest in studies comparing sublobar resection with lobectomy has increased in recent years. It also presents both quantitative and qualitative analyses of the most cited articles in the literature on this topic. Therefore, it can serve as a guide for researchers.

       BACKGROUND: Sterotactic radiosurgery is becoming an integral modality in the management of intracranial meningiomas, both as the primary treatment or as adjuvant therapy. This study analyzes the scholarly impact of the top 100 cited articles on the stereotactic radiosurgical management of intracranial meningiomas.
    METHODS: A ranked list of the 100 most-cited articles was generated using the Scopus database by searching the keywords 'intracranial meningioma' and 'stereotactic radiosurgery'. All articles were then evaluated on multiple criteria regarding both the publication of the articles (year of publication, journal, country of origin, and authors) as well as their methods and foci (type of study, location of studied meningiomas, and type of radiosurgical modality). Quantitaitve and qualitative analyses were then performed from the collected data.
    RESULTS: The most frequently cited articles on stereotactic radiosurgical management of intracranial meningiomas were published between 1990 and 2016. The average citation-per-year across all papers in the list was 6.1. The most studied anatomic area of intracranial meningiomas was the skull base, with the cavernous sinus being the most well-studied specific site. The most utilized stereotactic radiosurgical modality was Gamma Knife radiosurgery. The country with the highest number of publications was the United States. Twenty-six percent of the articles were published in the journal Neurosurgery; Lunsford, Kondziolka, Flickinger, Sheehan, and Pollock were respectively the most frequent listed authors among this list. The most active academic institute publishing on this topic was the University of Pittsburgh Medical Center.
    CONCLUSION: Stereotactic radiosurgery is an integral modality in the management of intracranial meningiomas. This bibliometric analysis sheds the light on the ways in which intracranial meningiomas have been studied in the past two decades in order to identify trends among neurosurgeons and radiation oncologists and to reveal areas of rising and declining focus.

       PURPOSE: To highlight the scientific progress in immunotherapy of urological cancer by identifying and analyzing the 100 top-cited (T100) articles from the last 15 years.
    METHODS: Papers in immunotherapy of urological cancer were identified from Clarivate Web of Science Core Collection database. Data of the T100 articles and papers published in recent 2 years, including citations, topic, year of publication, country of origin, institution and authorship, were extracted and analyzed.
    RESULTS: Of the T100 articles, the citation number ranged from 7387 to 183 with a mean of 590.66. The USA led the field with 80 T100 articles and 53097 citations. Pro Sharma P from MD Anderson Cancer Center was at the top of list with 8 T100 articles (3 as first author and 6 as corresponding author). Memorial Sloan Kettering Cancer Center ranked first with 26 T100 articles and 22573 citations, followed by Johns Hopkins University with 21 T100 articles and 25095 citations. Forty-nine T100 articles were related to the renal cancer, followed by prostate cancer (29), bladder cancer (13) and urothelial cancer (13). According to the type of immunotherapy, most T100 articles were related to ICI (55 articles) and vaccine (19 articles).
    CONCLUSIONS: It is the first bibliometric analysis to identify the T100 articles on immunotherapy of urological cancer. The USA made great contribution in the field of immunotherapy related to urological cancer. Renal, bladder and prostate cancers were the major organs treated by immunotherapy especially by ICIs and vaccines. The multiple aspects of ICIs research in renal and bladder cancer and the neoantigen-based vaccine therapy will be hotspots for future research.

       BACKGROUND: Bone metastasis (BM) has become an important health problem. In recent years, studies on BM are growing rapidly, but there were no bibliometric studies regarding BM. This study aimed to illustrate the overall knowledge structure and development trends of BM.
    METHODS: Research datasets were acquired from the Web of Science database. The time span was defined as "1980-2020". VOS viewer and Citespace software was provided to analyze the data and generate visualization knowledge maps. Annual trends of publications, distribution, H-index status, co-authorship status, and research hotspots were analyzed.
    RESULTS: Six hundred eighty-two publications met the requirement. USA published most papers (264, 38.7%), and both total citations (13,997) and H-index (57) of USA ranked first. The most productive institution on BM is Amgen Inc. (43). Supportive Care in Cancer (24) published the most papers on BM. "Safety", "skeletal related event", "open label", "management", "health", and "prognosis" are the research hotspots in the recent years.
    CONCLUSION: In this study, we conduct a systematic and comprehensive analysis on the research in BM field. The publication number was rising in recent years stably. USA contributed mostly not only in quality, but also in quantity. Amgen Inc. published the largest number of articles, Supportive Care in Cancer was the most productive journal related to BM. "Safety", "skeletal related event", "open label", "management", "health", and "prognosis" are the research hotspots in recent years. We believe this study can not only show the global research overview in past 40 years but also point the research trend of BM in the future.

       Purpose: Bibliometric studies have been established methods of analysing publications on a particular topic. These studies have been done on various orthopaedic topics and are increasing. The advantages of these studies have been highlighted in previous publications. Although some studies have been done on Indian publications from other specialties, those analysing Indian Orthopaedic Publications are lacking.
    Methods: We performed a search in Scopus to look for all publications related to orthopaedics from India. Our search strategy in Scopus included ((TITLE-ABS-KEY(Orthopaedics OR Orthopaedics) AND AFFIL(India)) AND PUBYEAR > 2009 AND PUBYEAR < 2020) which resulted in 3270 articles on 02/11/2021. We analyzed the most publishing universities, city, state, specialty, authors, and anatomic location of these publications. We also mined the data to draw word clouds based on data obtained from the titles of articles, keywords and the affiliations of each of the articles published.
    Results: Tamil Nadu and New Delhi and their institutes appear to be the epicenter of publication activities in Orthopaedics in India. There has been a healthy trend of growth of articles in the orthopaedic specialty. Since there is a significant overlap of technology and engineering, it is not surprising to see engineering and technology institutes among the top 10 published institutes and even journals for the publications on orthopaedics.
    Conclusion: There has been a steady increase in the number of publications in the last decade. New Delhi and its Universities and Institutes appear to contribute the majority of citations and publications related to orthopaedics. Journal of Clinical Orthopaedics and Trauma was the most publishing journal for Indian authors on Orthopaedic related articles.

       PURPOSE: To determine the research output of Caribbean nurses and midwives.
    METHODS: We searched the Scopus database to identify publications by Caribbean nurses and midwives during the period 2000-2020. Publications were included in the analysis if they had at least one author who was either a nurse or midwife and affiliated with a Caribbean geographic location. All publication types and languages were included in the analysis. Organization analysis and collaboration networks were created using the VOS Viewer application.
    FINDINGS: The number of Scopus publications by Caribbean nurses and midwives progressively grew from 22 in 2000 to 584 in 2020. Cuba recorded the highest number of nursing research publications (319) followed by Jamaica (92), and Puerto Rico (59). Most publishing institutions were universities. The University of the West Indies (Jamaica) ranked highest with 15.2% of publications, followed by Universidad de Ciencias Médicas de La Habana with 14.4% of publications, Universidad de Puerto Rico ranked third with 9.8% of publications. The majority of publications (83.6%) were peer reviewed research articles, while review articles accounted for 9.8% of publications. Six out of the ten journals that published most research done by Caribbean nurse researchers were Cuban journals which published a total of n = 250 (75.8%) articles. All six journals had no impact factor and had low cite scores.
    CONCLUSIONS: Our analysis of bibliometric indicators suggest that recent and steady growth in nursing and midwifery research in the Caribbean has had low visibility. Equipping nurses and midwives with the necessary knowledge and skills to lead, teach, and conduct high quality research through doctorate level education is an imperative for increasing research productivity among Caribbean nurses and midwives.
    CLINICAL RELEVANCE: Nursing and midwifery research is critical for evidence-based nursing and midwifery practice. High quality and context specific research evidence will enable Caribbean nurses and midwives to provide quality and culturally sensitive nursing and midwifery care and contribute to evidence informed policy decisions.

      Moyamoya disease is a rare cerebrovascular condition involving stenotic carotid arteries and the formation of abnormal blood vessels. In this study, we aimed to characterize the key players involved in moyamoya research at the individual and institutional level and to identify the critical publications that have advanced our understanding of this disease. We performed a title-specific search of the Web of Science database using the search term "moyamoya" for publications dating from 1900 to April 2020. The 100 most frequently cited articles were obtained, screened for duplicates, and reviewed by 2 independent reviewers. These 100 articles were cited an average of 150 times each (range, 74 to 1,360 citations per article). Publication dates ranged from 1969 to 2016, with the largest number of publications (n=40) cited between 2000 and 2009. The article with the greatest number of citations (1,360 citations) was "Cerebrovascular 'moyamoya' disease: disease showing abnormal net-like vessels in base of brain," by Suzuki and Takaku, published in the Archives of Neurology, 1969. Stroke published the greatest number of the most frequently cited articles (23 of 100). The institution that contributed the most articles was Tohoku University (16%); the majority of the most frequently cited articles originated in Japan (62%). We identified the 100 most cited articles on moyamoya disease over the past 51 years to recognize significant and impactful works. These results can be used as a guide to evaluate our current understanding of moyamoya disease and to direct future efforts.

      In recent years, emerging contaminants have been found in the wastewater, surface water, and even drinking water, which should be treated to ensure the safety of our living environment. In this study, we provide a comprehensive summary of wastewater treatment and emerging contaminants research from 1998 to 2021 by using the bibliometric analysis. This study is conducted based on the Web of Science Core Collection Database. The bibliometix R-package, VOSviewer and CiteSpace software are used for bibliometric analysis and science mapping. A dataset of 10, 605 publications has been retrieved. The analysis results show that China has produced the most publications. China and the United States have the closest cooperation. Analysis of the most cited papers reveals that the purification or removal techniques such as ozonation or membrane filtration can effectively remove pharmaceutical compounds from the water environment. We also found that the efficient detection of emerging contaminants and the optimization of removal methods are current challenges. Finally, future research directions are discussed.

      Publications are commonly used to evaluate the productivity and impact of research programs. Traditional metrics examine publication impact through slowly accumulating academic citations. 'Altmetrics' are a new way to describe early publication influence in non-academic media/community spheres (news, tweets, blogs). Articles with significant altmetric attention make a big splash of immediate impact, whereas papers with high rates of academic citation reflect ripple effects of influence over time. Past research has found weak associations between altmetrics and academic citations. However, no previous research has focused on clinical/translational research, which aims to translate scientific discoveries to public use. Further, no previous research has assessed the relationship between altmetrics and modern citation impact factors like the NIH's Relative Citation Ratio (RCR). It is also unclear whether publication in journals with higher journal impact factors (JIF) may drive both public attention and academic impact. We investigated whether early altmetric indicators of splash predict citation ripples, beyond the effect of the JIF. For a portfolio of 2,188 publications supported by the NIH's Georgia Clinical and Translational Science Alliance from 2007-2020, we collected 2020 Altmetric Attention Scores (AAS), 2020 JIFs, and 2021 RCRs. All three were significantly correlated with one another. Regression analyses revealed that AAS significantly predicts later RCR, controlling for JIF and publication year. Findings indicate that in clinical/translational science, articles that make a big splash of altmetric attention have ripple effects through increased citation influence, which is not entirely due to publication in higher impact journals. Altmetric attention may be a useful early indicator of eventual influence and potential for translational advancement.

      Peer-review of manuscripts submitted to scholarly journals for publication dates back ~ 350 years and this process represents the foundation of scientific publishing. After a manuscript has undergone and survived a rigorous peer-review, this conveys a stamp of approval, because it signifies the work has been checked by independent experts in the scientific discipline concerned. The publication and citation track records of people instructed to appear as expert witness in civil and criminal litigation are important considerations. Using a publically available database, the most highly cited scientists in the discipline legal and forensic medicine were identified. For each scientist, a composite score was calculated based on six different citation metrics; (i) Total number of citations, (ii) H-index, (iii) Hm-index, which modifies the H-index for multi-authored papers, (iv) Citations to single-author papers, (v) Citations to single and first author papers and (vi) citations to single, first and last author papers. The top 100,000 most highly cited scientists from all disciplines were identified along with the top 2% of the most highly cited in each of 176 sub-fields. The latest version of the citation databases, up to the end of 2020, classified 14.163 people as having legal and forensic medicine as their primary research discipline. Of these, there were 29 names listed among the top 100,000 most highly cited in all disciplines and 299 were among the top cited 2% in their particular sub-field. More than 50% of the highly cited forensic practitioners resided in four countries (USA, Germany, UK and Australia). The top-ten most highly cited individuals were the same in all four versions of the database (2017, 2018, 2019 and 2020) and represented the sub-disciplines of toxicology (n = 3), genetics/DNA/heredity (n = 3), whereas two specialized in pathology/toxicology and two in pathology/genetics.

      Per- and polyfluoroalkyl substances (PFASs) are widely used in food packaging, non-stick pots, and surfactants. However, their persistence in the environment, hazardous nature, and potential for bioaccumulation and long-range transport have alarmed an increasing number of scholars and research institutions. Although several literature reviews on PFASs research exist, only a few of them have considered bibliometric indices. In this study, 3,373 PFASs-related articles published between 2001 and 2018 were analyzed using a bibliometric analysis method based on the Science Citation Index (SCI) Expanded. The software tools for mapping knowledge domain (MKD) (VOSviewer and Science of Science (Sci2)) were used to analyze the performance of contributors and PFASs research topics, hotspots, and trends. Our results reveal that the number of PFASs-related articles published annually has increased significantly, with most originating from the United States (followed by those from China). The Chinese Academy of Sciences has published the most articles. A comprehensive analysis of title, keywords, and keywords plus showed that PFASs research hotspots include humans, precursors, and detection methods, with the main focuses being environmental science, toxicology, and environmental engineering. The four main research topics of PFASs were identified, and a literature review was carried out for each one. Overall, this study can supply researchers with a deeper understanding of the development of PFASs studies and provide a comprehensive data reference for researchers to further grasp the research direction in this field.

       BACKGROUND: Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common urological disease, and research on CP/CPPS has increased over the past 50 years. However, few studies have statistically analyzed these publications. In this work, we conducted the knowledge domain and highlighted current research hotspots and emerging trends in CP/CPPS from 1970 to 2020 based on VOSviewer and CiteSpace.
    METHODS: Relevant original articles were obtained from the Web of Science (WoS) database between 1970 and 2020. VOSviewer and CiteSpace software were used to perform the analysis and visualization of scientific productivity and emerging trends.
    RESULTS: Our results show that the articles related to CP/CPPS have dramatically increased every year from 1 publication in 1970 to 111 publications in 2020. The USA dominated the field in all countries, and Queen's University (Canada) has more extensive cooperating relationships with other institutions. J. Curtis Nickel may have a significant influence on CP/CPPS research with more publications and cocitations. The Journal of Urology is the foremost productive journal and has the most citations of all the journals. A total of 11 major clusters were explored based on the reference cocitation analysis (RCA). Definition, incidence rate or clinical characteristics, etiology or pathogenesis, epidemiological studies (cross-sectional study and cohort study), clinical studies (inflammation, pain, LUTS, α-blockers, antibiotic) and relationships with other diseases [benign prostatic hyperplasia (BPH), prostate cancer, sexual dysfunction] are the knowledge bases for CP/CPPS research. The treatment mode also changed gradually from anti-inflammatory therapy to symptom improvement, and NIH-CPSI was taken as the evaluation criterion.
    CONCLUSIONS: This scientometric study comprehensively reviewed publications related to CP/CPPS during the past 50 years using quantitative and qualitative methods, and the information provides some references for scholars to conduct further research on CP/CPPS.

       BACKGROUND: Significant links between the microbiota and human health have emerged in the last 20 years. A correlation has recently been demonstrated between changes in the gut microbiota and the development of cancer. This study aimed to use bibliometric analysis of the published gut microbiome and cancer literature to present the research status and summarize the hotspots for frontier studies.
    METHODS: A literature search for research on the gut microbiome and cancer research from 2001 to 2020 was conducted using the Scopus database on 20 March 2021. VOSviewer software (version 1.6.16) was used to perform the visualization analysis.
    RESULTS: From 2001 to 2020, a total of 2061 publications were retrieved. Annual publication output grew from 10 in 2001 to 486 in 2020. The USA had the largest number of publications, making the largest contribution to the field (n  = 566, 27.46%). Before 2016, most studies focused on the 'effect of probiotics on cancer'. The latest trends showed that 'microbiota composition and gene expression' and 'host-microbiome interaction in cancer immunotherapy' would be more concerned more widely in the future.
    CONCLUSIONS: Research on 'microbiota composition and gene expression' and 'host-microbiome interaction in cancer immunotherapy' will continue to be the hotspot. Therefore, this study provides the trend and characteristics of the literature on the gut microbiota and cancer literature, which provided a useful bibliometric analysis for researchers to conduct further research.

       Objectives: Diabetic foot ulcer (DFU) is one of the devastating complications of diabetes. It has high mortality and disability rates. The number of research articles on DFUs has increased. This study was designed to explore the global trends and research hotspots of DFUs to benefit researchers in shaping future research directions.
    Methods: Literatures relating to DFU from 2004 to 2020 were retrieved from the Science Citation Index Expanded (SCI-expanded) of Web of Science Core Collection (WoSCC). The current status of DFU research (including publications, journals, the performances of relevant countries, institutions, and authors and the research trends and hotspots of DFU) was analyzed with the WoSCC. VOSviewer v1.6.10.0 was utilised for cocitation, coauthorship, cooccurrence analyses, and bibliographic coupling.
    Results: A total of 5869 publications on DFUs were retrieved. We performed a longitudinal review of publications over 17 years: 4500 articles and 865 review articles on DFUs published from 2004 to 2020 were analyzed. The total citation was 107,296. The USA (n = 1866), England (n = 606), and China (n = 599) were the three largest contributors. The University of Washington had the greatest number of publications within this time period (n = 103), and it had the most cooperative units and was in the core position in all research institutions, followed by the University of Manchester (n = 94) and the University of Miami (n = 92). Armstrong DG (91/1.69%) and Lavery LA (55/1.19%) should be regarded as scholars who have made outstanding contributions. The top journal with the greatest total link strength was Diabetes Care. Analysis showed that the global research hotspots of DFU focused on lower limb amputation, diabetic foot infection, and treatment and management of DFU. Studies on osteomyelitis, wound therapy and management, multidisciplinary integration and mechanism of DFUs, and its related diseases are the research fronts that should be closely watched in the future.
    Conclusions: This study revealed the current research status and hotspots in the domain of DFU over the past 17 years, which can help researchers to further pinpoint potential perspectives on hot topics and research frontiers.

      Bibliometric data are relatively simple and describe objective processes of publishing articles and citing others. It seems quite straightforward to define reasonable measures of a researcher's productivity, research quality, or overall performance based on these data. Why do we still have no acceptable bibliometric measures of scientific performance? Instead, there are hundreds of indicators with nobody knowing how to use them. At the same time, an increasing number of researchers and some research fields have been excluded from the standard bibliometric analysis to avoid manifestly contradictive conclusions. I argue that the current biggest problem is the inadequate rule of credit allocation for multiple authored articles in mainstream bibliometrics. Clinging to this historical choice excludes any systematic and logically consistent bibliometrics-based evaluation of researchers, research groups, and institutions. During the last 50 years, several authors have called for a change. Apparently, there are no serious methodologically justified or evidence-based arguments in the favor of the present system. However, there are intractable social, psychological, and economical issues that make adoption of a logically sound counting system almost impossible.

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

       BACKGROUND: Accurate citation practices are key to furthering knowledge in an efficient and valid manner. The aim of this study is to investigate the prevalence of citation inaccuracies in original research from the top-ranked surgical journals and to evaluate the impact level of evidence has on citation inaccuracy.
    METHODS: A retrospective study evaluating the citation accuracy of the top 10 ranked surgical journals using the SJCR indicators. For each year between 2015 and 2020, the top 10 cited studies were selected, totaling 60 studies from each journal. From each individual study, 10 citations were randomly selected and evaluated for accuracy. Categories of inaccuracy included fact not found, study not found, contradictory conclusion, citation of a citation, and inaccurate population.
    RESULTS: A total of 5973 citations were evaluated for accuracy. Of all the citations analyzed, 15.2% of them had an inaccuracy. There was no statistically significant difference in citations inaccuracy rates among the years studied (P = .38) or study level of evidence (P = .21). Annals of Surgery, Plastic and Reconstructive Surgery and Annals of Surgical Oncology had significantly more citation inaccuracies than other journals evaluated (P < .05). JAMA Surgery, The Journal of Endovascular Therapy and The Journal of Thoracic and Cardiovascular Surgery had significantly fewer citation inaccuracies.
    CONCLUSIONS: Although 84.8% of citations from 2015-2020 were determined to be accurate, citation inaccuracies continue to be prevalent throughout highly-ranked surgical literature. There were no significant differences identified in citation inaccuracy rates between the years evaluated or based on study level of evidence.

       BACKGROUND: Digital teaching in medical education has grown in popularity in the recent years. However, to the best of our knowledge, no bibliometric report to date has been published that analyzes this important literature set to reveal prevailing topics and trends and their impacts reflected in citation counts.
    OBJECTIVE: We used a bibliometric approach to unveil and evaluate the scientific literature on digital teaching research in medical education, demonstrating recurring research topics, productive authors, research organizations, countries, and journals. We further aimed to discuss some of the topics and findings reported by specific highly cited works.
    METHODS: The Web of Science electronic database was searched to identify relevant papers on digital teaching research in medical education. Basic bibliographic data were obtained by the "Analyze" and "Create Citation Report" functions of the database. Complete bibliographic data were exported to VOSviewer for further analyses. Visualization maps were generated to display the recurring author keywords and terms mentioned in the titles and abstracts of the publications.
    RESULTS: The analysis was based on data from 3978 papers that were identified. The literature received worldwide contributions with the most productive countries being the United States and United Kingdom. Reviews were significantly more cited, but the citations between open access vs non-open access papers did not significantly differ. Some themes were cited more often, reflected by terms such as virtual reality, innovation, trial, effectiveness, and anatomy. Different aspects in medical education were experimented for digital teaching, such as gross anatomy education, histology, complementary medicine, medicinal chemistry, and basic life support. Some studies have shown that digital teaching could increase learning satisfaction, knowledge gain, and even cost-effectiveness. More studies were conducted on trainees than on undergraduate students.
    CONCLUSIONS: Digital teaching in medical education is expected to flourish in the future, especially during this era of COVID-19 pandemic.

       Background: COVID-19 is causing a grave global health and economic crisis and the fight against the pandemic has led to unprecedented scientific activity. Bibliometrics could be a useful tool for guiding future researches lines and promoting international collaboration for an effective treatment. For this purpose, we have conducted a bibliometric analysis of scientific publications on drugs and therapies used to treat COVID-19 during 2020.
    Methods: Data source: Web of Science. We gathered data on scientific production relating to drugs used to treat COVID-19. We calculated impact factors and analyzed production by institution, country, and journal, visualizing our results in bibliometric networks.
    Results: In 1 year, production relating to COVID-19 exceeded 100 000 publications, with over 6,500 on Drugs and COVID-19. Research into hydroxychloroquine and chloroquine, remdesivir, lopinavir and ritonavir, tocilizumab and convalescent plasma is particularly noteworthy. Mean citations/study range from 11.9 to 15.4. Producer institutions fall into three groups: one in the US and centered on Harvard Medical School; another in Europe led by INSERS; and another in China led by Huazhong University of Science and Technology. Production by journal is widespread but the Journal of Medical Virology, International Journal of Antimicrobial Agents, and American Journal of Transplantation are noteworthy.
    Conclusions: The volume of research that is currently under way is comparable to the magnitude of the pandemic itself. Such a high volume of studies is infrequent and the impact they have achieved has no known precedent. The producing countries are those with highest incidence of the pandemic and greatest scientific potential; moreover, inter-agency and international collaboration has reached extraordinarily high levels.

      Glucoamylase is one of the most widely used enzymes in industry, but the development background and existing circumstances of industrial glucoamylase were not described by published articles. CiteSpace, a powerful tool for bibliometric, was used to analyze the past, existing circumstances, and trends of a professional field. In this study, 1820 Web-of-Science-indexed articles from 1991 to 2021 were collected and analyzed by CiteSpace. The research hotspots of industrial glucoamylase, like glucoamylase strain directional improvement, Aspergillus niger glucoamylase, glucoamylase immobilization, application of glucoamylase in ethanol production, and "customized production" of porous starch, were found by analyzing countries, institutions, authors, keywords, and references of articles. PRACTICAL APPLICATIONS: The research progress of glucoamylase with industrial potential was analyzed by CiteSpace, and a significant research direction of glucoamylase with industrial potential was found. This is helpful for academic and corporate audiences to understand the current situation of glucoamylase with industrial potential and carry out follow-up works.

       Objective: The database http://cedd.saglik-network.org (CEDD-NET) has been operating since 2013 in Turkey. All pediatric endocrinologists can propose projects to this network. The aim of our study is to determine the impact of CEDD-NET on the transformation of multicenter studies into scientific publications and assess the academic characteristics of the studies that have been transcribed into publication.
    Materials and Methods: In our study, all the studies that were opened to patient admission on the website between August 26, 2013 and March 1, 2021 were reviewed. A total of 30 studies were accepted and opened for data entry. The median data collection period was 12 (1.5-24) months, while the median number of researchers participated was 23 (3-180), the median number of cases was 120 (26-192). The average cost was $ 2113 (1370-3118). Out of 30 studies, data entry was completed for 27. Sixteen publications were produced from 14 studies, 13 ot them have not published yet. The median time from the end of data entry to publication of the study was 686 (168-1608) days. While the median impact factor of the journals in which the studies were published was 1.803 (1.278-5.399), the median number of citations was 6.5 (0-49), and cited by 99 times in Web of Science indexed journals in total.
    Results: As a result, in light of all this data, CEDD-NET is productive and effective as all the publications are of high quality that have been published in the Q1-Q2 categories.
    Conclusion: This study shows the benefits and necessity of establishing nationwide databases, even covering more than one country, in specialized branches, such as pediatric endocrinology where rare diseases are of concern.

       OBJECTIVE: To assess the quantity and impact of research publications among US acute care hospitals; to identify hospital characteristics associated with publication volumes; and to estimate the independent association of bibliometric indicators with Hospital Compare quality measures.
    DATA SOURCES: Hospital Compare; American Hospital Association Survey; Magnet Recognition Program; Science Citation Index Expanded.
    STUDY DESIGN: In cross-sectional studies using a 40% random sample of US Medicare-participating hospitals, we estimated associations of hospital characteristics with publication volumes and associations of hospital-linked bibliometric indicators with 19 Hospital Compare quality metrics.
    DATA COLLECTION/EXTRACTION METHODS: Using standardized search strategies, we identified all publications attributed to authors from these institutions from 1/1/2015 to 12/31/2016 and their subsequent citations through July 2020.
    PRINCIPAL FINDINGS: Only 647 of 1604 study hospitals (40.3%) had ≥1 publication. Council of Teaching Hospitals and Health Systems (COTH) hospitals had significantly more publications (average 599 versus 11 for non-COTH teaching and 0.6 for non-teaching hospitals), and their publications were cited more frequently (average 22.6/publication) than those from non-COTH teaching (18.2 citations) or non-teaching hospitals (12.8 citations). In multivariable regression, teaching intensity, hospital beds, New England or Pacific region, and not-for-profit or government ownership were significant predictors of higher publication volumes; percentage of Medicaid admissions was inversely associated. In multivariable linear regression, hospital publications were associated with significantly lower risk-adjusted mortality rates for acute myocardial infarction (coefficient - 0.52, p = 0.01), heart failure (coefficient - 0.74, p = 0.004), pneumonia (coefficient - 1.02, p = 0.001), chronic obstructive pulmonary disease (coefficient - 0.48, p = 0.005), and coronary artery bypass surgery (coefficient - 0.73, p < 0.0001); higher overall Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) ratings (coefficient 2.37, p = 0.04); and greater patient willingness to recommend (coefficient 3.38, p = 0.01).
    CONCLUSIONS: A minority of US hospitals publish in the biomedical literature. Publication quantity and impact indicators are independently associated with lower risk-adjusted mortality and higher HCAHPS scores. This article is protected by copyright. All rights reserved.

      We investigated gender inequality in the National Institutes of Health (NIH) funding for hematologic malignancies and cellular therapies (HMCT). The data were retrieved from the NIH Research Portfolio Online Reporting Tools (RePORT). In 2018-2019, 1834 grants totaling $799 million were awarded (men 71% vs. women 29%) to 975 principal investigators (PIs), including 680 (70%) male PIs and 295 (30%) female PIs. There was no significant gender difference in the mean grant amount per PI. Male PIs as compared to female PIs had a higher h-index (44 vs 31, p < 0.001), a higher number of publications (159.5 vs 94, p < 0.001), and higher years of active research (26 vs 21, p < 0.001). In multivariate analyses, a higher h-index independently predicted a higher mean grant amount per PI (p = 0.010), and female PIs were independently less likely to have a higher h-index (p < 0.001). Our study shows significant gender disparity in the NIH funding for HMCT research.

      Intermediate filaments were first described in muscle in 1968, and desmin was biochemically identified about 10 years afterwards. Its importance grew after the identification of desminopathies and desmin mutations that cause mostly cardiopathies. Since its characterization until recently, different functions have been attributed to desmin. Here, we use bibliometric tools to evaluate the articles published about desmin and to assess its several putative functions. We identified the most productive authors and the relationships between research groups. We studied the more frequent words among 9734 articles (September 2021) containing "desmin" on the title and abstract, to identify the major research focus. We generated an interactive spreadsheet with the 934 papers that contain "desmin" only on the title that can be used to search and quantify terms in the abstract. We further selected the articles that contained the terms "function" or "role" from the spreadsheet, which we then classified according to type of function, organelle, or tissue involved. Based on the bibliographic analysis, we assess comparatively the putative functions, and we propose an alternative explanation for the desmin function.

      When examining research articles on the aging strategies, four ideals (i.e., successful aging, healthy aging, productive aging and active aging) could be explored by conducting bibliometric analyses. For the literature analysis, general information on the four aging ideals was understood through visualization analysis; the intellectual base and research hotspots were intuitively observed. CiteSpace was used as the method to conduct the co-occurrence analysis of keywords in order to obtain research trends and cutting-edge knowledge in the field of aging-related policies. Subsequently, the study revealed the nature of the link between these four aging ideals and disclosed the connection between their fundamental principles. The study ultimately enhanced the understanding of the diverse contexts that have impacted the way in which these ideals influence policy, which has caused dissimilar strategies for policy development. The study also extended the discussion of the definitions of and relationships between these four ideals with the goal of identifying new directions for aging-related practice and providing innovative insights and references for investigators.

       Purpose: There is a known gender gap in oncology publishing with worse disparities within specialty fields such as radiation oncology. There has been a significant increase in the number of articles submitted to academic journals during the pandemic. Several analyses have suggested that the pandemic has had a disproportionate effect on academic productivity of women in academia, as measured by article publication rates.
    Materials and Methods: The gender of first/co-first and corresponding/co-corresponding authors, as well as nonsenior versus senior status and manuscript type, for all articles published by Advances from its inception in December 2015 to the end of February 2020 was compared with those published between March 1, 2020, and May 31, 2020: the months during which the onset of the COVID-19 pandemic in North America began.
    Results: This examination of papers published during COVID-19 did not indicate a statistically significant decrease in the overall proportion of women publishing in Advances (P = .76). For nonsenior female authors, this proportion fell just short of statistical significance (39% vs 19%, P = .051). When only scientific manuscripts were considered, there was a statistically significant decrease in publications by nonsenior female first authors during the early months of the pandemic (37% vs 11%, P = .02).
    Conclusions: During the early months of the COVID-19 pandemic, nonsenior female researchers participated less in article publishing in radiation oncology.

      Recent literature has demonstrated the associations between social media attention, as measured by altmetric attention score (AAS), and higher citation rates across medical disciplines. Despite increasing use of AAS, an understanding of factors associated with higher AAS and social media attention remains lacking. Furthermore, if this increased attention correlates with a higher methodological quality and lower biases has not been determined. Therefore, the purpose of the current study was to determine the relationship between methodological quality, study biases and the AAS in randomized controlled trials (RCTs). All RCTs from 2016 in the New England Journal of Medicine (NEJM), Journal of the American Medical Society (JAMA), and Lancet were extracted and the (1) AAS; (2) Methodological Bias (JADAD Scale); Study Bias (Cochrane Risk-of-Bias tool for RCTs) recorded. A total of 296 RCTs with a median (range) AAS and citation rate per article of 234.0(7-4079) and 165.0(4-3257), respectively, were included. The AAS was positively associated with citation rate (β 0.19, 95% CI 0.10-0.29; P < 0.001). Methodological bias was not associated with the AAS (β - 36.3, 95% CI - 83.5-10.9; P = 0.131), but was negatively associated with higher citation rates (β - 66.4, 95% CI - 106.0 to - 26.9; P = 0.001). The number of study biases was not associated with the AAS (β 43.7, 95% CI - 6.3-93.7;P = 0.086), but was positively associated with a higher citation rate (β 64.5, 95% CI 22.4-106.6; P = 0.003). The online attention of RCTs in medical journals was not necessarily reflective of high methodological quality and minimal study biases, but was associated with higher citation rates. Researchers and clinicians should critically examine each article despite the amount of online attention an article receives as the AAS does not necessarily reflect article quality.

       Background: A journal's impact factor (IF) and total citations are often used as indicators of its publication quality. Furthermore, journals that require authors to abide by reporting guidelines or conduct trial registration generally have a higher quality of reporting. In this study, we sought to explore the potential associations between the enforcement of reporting guidelines or trial registration and a surgical journal's IF or total citations in order to find new approaches and ideas to improve journal publication quality.
    Methods: We examined surgical journals from the 2018 Journal Citation Report's Expanded Scientific Citation Index to quantify the use of reporting guidelines or study registration. We reviewed the "instructions for authors" from each journal and used multivariable linear regression analysis to determine which guidelines were associated with the journal IF and total citations. The dependent variable was the logarithm base 10 of the IF in 2018 or the logarithm base 10 of total citations in 2018 (the results were presented as geometric means, specifically the ratio of the "endorsed group" results to "not endorsed group" results). The independent variable was one of the requirements (endorsed and not endorsed). Models adjust for the publication region, language, start year, publisher and journal size (only used to adjust total citations).
    Results: We included 188 surgical journals in our study. The results of multivariable linear regression analysis showed that journal IF was associated (P < 0.01) with the following requirements: randomized controlled trial (RCT) registration (geometric means ratio (GR) = 1.422, 95% CI [1.197-1.694]), Consolidated Standards of Reporting Trials (CONSORT) statement (1.318, [1.104-1.578]), Preferred Reporting Items for Systematic Reviews Meta-Analyses (PRISMA) statement (1.390, [1.148-1.683]), Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement (1.556, [1.262-1.919]), Standards for Reporting Diagnostic Accuracy (STARD) statement (1.585, [1.216-2.070]), and Meta-analysis of Observational Studies in Epidemiology (MOOSE) statement (2.113, [1.422-3.133]). We found associations between the endorsement of RCT registration (GR = 1.652, 95% CI [1.268-2.153]), CONSORT (1.570, [1.199-2.061]), PRISMA (1.698, [1.271-2.270]), STROBE (2.023, [1.476-2.773]), STARD (2.173, [1.452-3.243]), and MOOSE statements (2.249, [1.219-4.150]) and the number of total citations.
    Conclusion: The presence of reporting guidelines and trial registration was associated with higher IF or more total citations in surgical journals. If more surgical journals incorporate these policies into their submission requirements, this may improve publication quality, thus increasing their IF and total citations.

      We examined how sharing autism research articles via social and news media was associated with citations and downloads. We included articles published in 2019 from three autism-focused journals. Every 10 Twitter shares yielded a 4.4% increase in article downloads and 5.2% increase in citations. Articles with at least one Facebook post had 23.3% more downloads than those without. Articles with at least one news story had 56.9% more downloads and 39.3% more citations than those without. Descriptive analysis indicated the most shared, downloaded, and cited articles focused largely on treatments or interventions. Autism researchers should continue sharing articles via Twitter and news media because it increases the reach of their work and may better engage research and autism community members.

      This study evaluates the gender distribution of Centralized Otolaryngology Research Efforts (CORE) grants by research subspeciality over the past decade. Demographic information on CORE grant recipients from 2010 to 2019 was extracted through an Internet search, and research projects were categorized by subspeciality. Of 343 grants awarded during this period, 127 (37%) were awarded to women. Analysis demonstrated lower absolute rates of CORE funding for women in all fields except pediatrics, but women receive a proportional number of grants for most subspecialities based on their representation within the field.

       OBJECTIVE: Our study assesses the impact of an author's social media presence on citation rates and readership of spine literature.
    METHODS: Altmetric database was queried for spine-related articles between 2016-2021; top 100 by Altmetric Attention Score(AAS) were assessed. Public profile presence, number of followers, number of posts, and promotion of articles were assessed for Twitter/Instagram. Social media profiles were identified by searching for the author's name followed by "Twitter" or "Instagram" on Google.com or searching each platform. Descriptive statistics assessed social media use and attention metrics. Negative binomial regression assessed presence/promotion/number of followers/number of posts on Twitter/Instagram as predictors of Dimensions citation rates/AAS/Mendeley reader counts, while accounting for time passed since publication.
    RESULTS: Twitter promotion was noted for 9.0% of articles and Instagram promotion for 1.0%. Mean numbers of Twitter and Instagram followers were 447.9±1406.1(range 0-9079) and 173.2±1097.1(range 0-10700). Mean numbers of Twitter and Instagram posts were 411.6±1210.5 and 18.4±96.4, respectively. Dimensions citations ranged from 0-641, AAS from 79-2257, and Mendeley readers from 2-1854. Following negative binomial regression, Instagram presence was identified as a significant predictor of Mendeley readers(p=0.043), number of Twitter posts was a significant predictor of AAS(p=0.008). Additionally, Twitter presence was identified as a negative predictor of Mendeley Readers(p=0.005) and Twitter promotion was identified as a negative predictor of AAS (p=0.003).
    CONCLUSION: Activity on Twitter and Instagram may have variable associations with altmetrics of literature visibility and readership but with citation rates. Interestingly, presence/promotion on Twitter predicted less attention/readership, while Instagram presence predicted higher Mendeley readership.

      Anomaly detection is one of the most active research areas in various critical domains, such as healthcare, fintech, and public security. However, little attention has been paid to scholarly data, that is, anomaly detection in a citation network. Citation is considered as one of the most crucial metrics to evaluate the impact of scientific research, which may be gamed in multiple ways. Therefore, anomaly detection in citation networks is of significant importance to identify manipulation and inflation of citations. To address this open issue, we propose a novel deep graph learning model, namely graph learning for anomaly detection (GLAD), to identify anomalies in citation networks. GLAD incorporates text semantic mining to network representation learning by adding both node attributes and link attributes via graph neural networks (GNNs). It exploits not only the relevance of citation contents, but also hidden relationships between papers. Within the GLAD framework, we propose an algorithm called Citation PUrpose (CPU) to discover the purpose of citation based on citation context. The performance of GLAD is validated through a simulated anomalous citation dataset. Experimental results demonstrate the effectiveness of GLAD on the anomalous citation detection task.

      The COVID-19 outbreak has posed an unprecedented challenge to humanity and science. On the one side, public and private incentives have been put in place to promptly allocate resources toward research areas strictly related to the COVID-19 emergency. However, research in many fields not directly related to the pandemic has been displaced. In this paper, we assess the impact of COVID-19 on world scientific production in the life sciences and find indications that the usage of medical subject headings (MeSH) has changed following the outbreak. We estimate through a difference-in-differences approach the impact of the start of the COVID-19 pandemic on scientific production using the PubMed database (3.6 Million research papers). We find that COVID-19-related MeSH terms have experienced a 6.5 fold increase in output on average, while publications on unrelated MeSH terms dropped by 10 to 12%. The publication weighted impact has an even more pronounced negative effect (-16% to -19%). Moreover, COVID-19 has displaced clinical trial publications (-24%) and diverted grants from research areas not closely related to COVID-19. Note that since COVID-19 publications may have been fast-tracked, the sudden surge in COVID-19 publications might be driven by editorial policy.

      Nowadays the agrifood system requires major transformations aimed at promoting sustainability, reducing waste and stimulating a change toward healthy sustainable diets. The scientific literature on the transition to sustainable food models continues to develop rapidly and there is an urgent need to systematize its knowledge structure and thus make future research more vigorous. Recently, several studies have focused on certain aspects of supply chain, such as traceability or decision-making frameworks, but a systematic review of the role of sustainability within the agrifood supply has never been carried out. Through a bibliometric analysis combined with network and content analyses, the present study is aimed at identifying homogeneous areas in the field of agrifood supply chains, investigating the role of innovation technology in the transition to sustainability. The bibliometric results showed that sustainable agrifood supply chains are experiencing an evolving positive trend and represent a challenging research topic which is capturing the attention of scholars. From the network and overlay visualization of keyword co-occurrences four different research clusters were identified and the blockchain emerged as central topic in the field of food security and safety. The content analysis highlighted greater attention to the environmental pillar, compared to economic and social pillars of the sustainability paradigm. Lack of studies was also observed on the post-consumption phase of the agrifood supply chain, which could represent a research gap to be fulfilled in the light of circular economy.

       OBJECTIVE: The Great Barrington Declaration (GBD) and the John Snow Memorandum (JSM), each signed by numerous scientists, have proposed hotly debated strategies for handling the COVID-19 pandemic. The current analysis aimed to examine whether the prevailing narrative that GBD is a minority view among experts is true.
    METHODS: The citation impact and social media presence of the key GBD and JSM signatories was assessed. Citation data were obtained from Scopus using a previously validated composite citation indicator that incorporated also coauthorship and author order and ranking was against all authors in the same Science-Metrix scientific field with at least five full papers. Random samples of scientists from the longer lists of signatories were also assessed. The number of Twitter followers for all key signatories was also tracked.
    RESULTS: Among the 47 key GBD signatories, 20, 19 and 21, respectively, were top-cited authors for career impact, recent single-year (2019) impact or either. For comparison, among the 34 key JSM signatories, 11, 14 and 15, respectively, were top cited. Key signatories represented 30 different scientific fields (9 represented in both documents, 17 only in GBD and 4 only in JSM). In a random sample of n=30 scientists among the longer lists of signatories, five in GBD and three in JSM were top cited. By April 2021, only 19/47 key GBD signatories had personal Twitter accounts versus 34/34 of key JSM signatories; 3 key GBD signatories versus 10 key JSM signatories had >50 000 Twitter followers and extraordinary Kardashian K-indices (363-2569). By November 2021, four key GBD signatories versus 13 key JSM signatories had >50 000 Twitter followers.
    CONCLUSIONS: Both GBD and JSM include many stellar scientists, but JSM has far more powerful social media presence and this may have shaped the impression that it is the dominant narrative.

      Introduction  Recent efforts to standardize reporting of surgeon experience in novel technique publications have recommended reporting of Tang level of expertise (LOE). Question/Purpose  The aim of this study was to document trends in LOE reporting for novel technique articles published in the Journal of Wrist Surgery and evaluate whether author experience affects novel research outcomes. Methods  A total of 261 articles published from 2018 to 2020 were reviewed. Articles describing novel surgical techniques were included and examined for Tang LOE. Author variables were collected online. Results  Eight percent (21/261) of articles discussed novel surgical techniques and one reported LOE. Nearly half (47.6%) of articles did not conduct statistical analysis. Four (19.0%) reported insignificant statistical results and 7 (33.3%) reported significant findings. All significant statistical findings were positive. Number of prior related publications by the senior author did not affect new technique result significance ( p  = 0.34). Discussion  From 2018 to 2020, only one article documented LOE. Authors' variables, including number of prior related publications, were not correlated with significant results in their new publications. This may suggest that an author's established experience in a novel technique, quantified by prior publications on the topic, does not make one more likely to achieve significantly better or worse outcomes in their reviewed Journal of Wrist Surgery study. Conclusions  Tang LOE is an important way for readers to classify expertise and should be reported, and potentially modified to better define contributing variables.

      COVID-19-related (vs. non-related) articles appear to be more expeditiously processed and published in peer-reviewed journals. We aimed to evaluate: (i) whether COVID-19-related preprints were favored for publication, (ii) preprinting trends and public discussion of the preprints, and (iii) the relationship between the publication topic (COVID-19-related or not) and quality issues. Manuscripts deposited at bioRxiv and medRxiv between January 1 and September 27 2020 were assessed for the probability of publishing in peer-reviewed journals, and those published were evaluated for submission-to-acceptance time. The extent of public discussion was assessed based on Altmetric and Disqus data. The Retraction Watch Database and PubMed were used to explore the retraction of COVID-19 and non-COVID-19 articles and preprints. With adjustment for the preprinting server and number of deposited versions, COVID-19-related preprints were more likely to be published within 120 days since the deposition of the first version (OR = 1.96, 95% CI: 1.80-2.14) as well as over the entire observed period (OR = 1.39, 95% CI: 1.31-1.48). Submission-to-acceptance was by 35.85 days (95% CI: 32.25-39.45) shorter for COVID-19 articles. Public discussion of preprints was modest and COVID-19 articles were overrepresented in the pool of retracted articles in 2020. Current data suggest a preference for publication of COVID-19-related preprints over the observed period.

       BACKGROUND: The outbreak of COVID-19 sweeping the globe in 2020 has caused widespread fear and threatened global health security. Compared to SARS and MERS, COVID-19 also causes severe respiratory diseases and even fatal diseases but have many differences, such as the unidentified gene sequence and replication mechanism. From SARS to MERS, and then to COVID-19, coronaviruses have significant variations in host adaptation, virus evolution, infectivity, spread, and pathogenicity due to its unique replication mechanism.
    METHODS: A field of research for the coronavirus replication in humans was visualized with a database covering 9177 kinds of literature in Web of Science from 2002 through October 2021 to provide cognitive direction for the epidemic situation of virus infection. Knowledge Mapping by CiteSpace and Bibliometrix Package in R Software was drawn to depict the underlying features of viral replication and changing trends of studies, with these analyses including co-citation, density visualization, keyword clustering, and time zone.
    RESULTS: The keyword frequencies of "replication," ''infection," and ''spike protein" repeatedly appeared in published papers. Coronavirus can promote or inhibit apoptosis, depending on the balance between viral protein and apoptotic factors. When the living environment of cells is irreversibly damaged by the virus, cells have to start the apoptosis mechanism to prevent the replication, transmission, and spread of the virus. The replication, assembly and transmission of coronavirus can inhibit cells from entering the apoptosis prematurely with the fusion of spike protein and cell receptor in human.
    CONCLUSION: Our results indicated that "viral infection," spike protein," and "mutation" might be future research hotspots on coronavirus replication in humans. The attention should be paid to the mutations of S protein and these mutants carrying mutations.

      Background: To evaluate how an international one-year intensive research training program for addiction medicine physicians contributed to subsequent research involvement and productivity. Methods: We prospectively compared addiction medicine physician fellows admitted to a one-year training program with non-admitted controls, using baseline questionnaire and peer-reviewed publication data. Participants' publication activity was assessed from fellowship application date onwards using biomedical databases (e.g., PubMed, Embase). Results: Between July 2014 and June 2020, which is six years of cohorts, 56 (39 women) physicians, both fellows (n = 25) and non-admitted applicants (n = 31), were observed and included in the study, contributing 261 person-years of observation. At baseline, in the fellows' cohort: 76% of participants (19/25) reported past research involvement, 24% (6/25) had one or more advanced graduate degrees (e.g., MPH), and the median number of peer-reviewed, first author publications was one (Interquartile Range [IQR] = 0-2). At baseline, in the controls' cohort: 84% of participants (26/31) reported past research involvement, 39% (12/31) had one or more advanced graduate degrees, and the median number of peer-reviewed, first author publications was zero. The physicians' training included internal medicine (n = 8), family medicine (n = 33), psychiatry (n = 5) and others (n = 4). At follow up, there was a significant difference between fellows (n = 25) and controls (n = 31) in total number of publications (Rate Ratio [RR] = 13.09, 95% Confidence Interval [CI], 5.01 - 34.21, p < 0.001), as well as first author publications (RR = 5.59, 95% CI, 2.23 - 14.06, p < 0.001). Conclusion: In the six-year observation period, fellows' productivity indicates undertaking this fellowship was associated with significant research outputs in comparison to controls, signaling successful training of addiction physicians to help recruit addiction medicine physicians to participate in addiction research.

      A wide array of existing metrics quantifies a scientific paper's prominence or the author's prestige. Many who use these metrics make assumptions that higher citation counts or more public attention must indicate more reliable, better quality science. While current metrics offer valuable insight into scientific publications, they are an inadequate proxy for measuring the quality, transparency, and trustworthiness of published research. Three essential elements to establishing trust in a work include: trust in the paper, trust in the author, and trust in the data. To address these elements in a systematic and automated way, we propose the ripetaScore as a direct measurement of a paper's research practices, professionalism, and reproducibility. Using a sample of our current corpus of academic papers, we demonstrate the ripetaScore's efficacy in determining the quality, transparency, and trustworthiness of an academic work. In this paper, we aim to provide a metric to evaluate scientific reporting quality in terms of transparency and trustworthiness of the research, professionalism, and reproducibility.

      As the world looks forward to turning a corner in the face of the COVID-19 pandemic, it becomes increasingly evident that international research cooperation and dialogue is necessary to end this global catastrophe. Last year, we initiated a research topic: "Infectious Disease Surveillance: Cooperative Research in Response to Recent Outbreaks, Including COVID-19," which aimed at featuring manuscripts focused on the essential link between surveillance and cooperative research for emerging and endemic diseases, and highlighting scientific partnerships in countries under-represented in the scientific literature. Here we recognize the body of work published from our manuscript call that resulted in over 50 published papers. This current analysis describes articles and authors from a variety of funded and unfunded international sources. The work exemplifies successful research and publications which are frequently cooperative, and may serve as a basis to model further global scientific engagements.

      Solid waste generation has been significantly accelerated by the rapid growth of economy and population worldwide. The traditional waste management focusing on waste utilization and disposal is unable to unravel the continuous depletion of finite natural resources. "Zero waste" as an integrated waste management method to promote waste reduction through a pack of strategies such as cleaner production and green consumption has emerged. Here, we systematically reviewed the researches on zero waste from a scientometric perspective, and visually unveiled the most productive countries, evolution process, main authors, major research areas, and documents of zero waste research domain. The results show that with increased publications, zero waste has become a multidisciplinary study area and food waste reduction is the biggest sub-network in zero waste research. The current research frontiers are mainly regarding "lean production," "consumer behavior," "productivity." Accordingly, this study proposed a pathway for realizing zero waste cities with three lanes: (1) research and development, (2) management method, and (3) policy and implementation. The findings are also expected to be beneficial to latecomer researches in the waste management field.

       BACKGROUND: For two decades, women have made up nearly half of medical school graduates, yet this is not translated to equity in promotion. We compare historical trends in the academic career pipeline between four specialties by gender.
    METHODS: Using Association of American Medical Colleges database, faculty gender and rank were examined in oncology, gastroenterology, cardiovascular medicine, and general surgery for the years 2000 and 2020.
    RESULTS: Cardiovascular medicine, gastroenterology and general surgery all had similar lower representation of women faculty in 2000 (17%, 17% and 15%) compared to oncology (26%). Cardiovascular medicine and general surgery have seen smaller increases in representation over the last 20 years compared to gastroenterology and oncology. Oncology and gastroenterology are projected to reach gender parity in 2024 and 2029, followed by general surgery in 2054. At the current rate, cardiovascular medicine will not reach gender parity until 2070.
    CONCLUSION: Oncology and gastroenterology, compared to cardiovascular medicine and general surgery, have seen larger gains in representation of women over the past two decades, including at Professor rank. Disparities persist in specific fields; lessons may be learned from other specialties in which women are more likely to be promoted to leadership positions.

       INTRODUCTION: As social media use continues to increase, parents and caregivers report using social media platforms as a source of health information. However, there are minimal regulations for social media content and health misinformation has been shared for various medical issues and urologic conditions. While internet content related to pediatric urology has been previously described, social media engagement for various pediatric urologic conditions have yet to be described.
    OBJECTIVE: To evaluate the evidence supporting articles engaged on social media that are related to common pediatric urologic conditions.
    STUDY DESIGN: A social media analysis tool was used to identify articles engaged through Facebook, Reddit, Twitter, and Pinterest between July 2020-2021. The top 5 articles related to toilet training, circumcision, cryptorchidism, testicular torsion, and hypospadias were identified. Article citations were reviewed and classified by Oxford levels of evidence. The content of each article was then reviewed and compared against supporting evidence on an independent literature search. Statistical analysis was completed with descriptive statistics, Mann-Whitney U, Wilcoxon signed rank, and bivariate correlation.
    RESULTS: Of the 25 articles reviewed, 8 (32%) were affiliated with medical journals, hospitals, or academic institutions and 17 (68%) were on non-affiliated websites with advertisements. There was greater social media engagement for articles related to toilet training and circumcision than testicular torsion, hypospadias, and cryptorchidism. No articles cited level 1 evidence and 32% of articles cited no evidence. Literature search for article content demonstrated a discrepancy between the level of evidence cited by articles compared to the evidence available in the literature to support article content. There was greater social media engagement for articles with no cited or supporting evidence and those not affiliated with medical journals, hospitals, or academic institutions.
    DISCUSSION: The findings in this study are consistent with trends reported for other urologic conditions, including genitourinary malignancy, female pelvic medicine and reconstructive surgery, nephrolithiasis, and sexual function. Parents without a medical background may have difficulty identifying whether articles shared on social media can be a reliable resource for health information. It is important to understand how information related to pediatric urologic conditions is engaged on social media so that misinformation can be addressed in clinical, online, and regulatory settings.
    CONCLUSION: There was greater social media engagement for articles with no cited or supporting evidence and those not affiliated with medical journals, hospitals, or academic institutions.
