       Background: The incidence and prevalence of gout have been steadily increasing globally, which has resulted in gout research attracting consistently increased attention. This study aimed to visualize the knowledge structure and research trends in gout research through bibliometrics to help understand the future development of basic and clinical research.
    Methods: Articles and reviews on gout from 2001 to 2021 were extracted from the Web of Science Core Collection database. CiteSpace and VOSviewer software were used to visualize the knowledge network of countries, institutions, authors, references, and keywords in this field. SPSS and Microsoft Excel software were used for curve fitting and correlation analysis.
    Results: A total of 3,259 articles and reviews were included. The number of publications about gout significantly increased yearly. Publications were mainly concentrated in North America, Europe, Oceania, and East Asia. The USA contributed most with 1,025 publications, followed by China and New Zealand. After adjusting for publications by population size and Gross Domestic Product (GDP), New Zealand ranked in the first place. GDP and international collaboration were significantly correlated with scientific productivity for gout research. University of Auckland and Professor Dalbeth Nicola were the most prolific institutions and influential authors, respectively. Rheumatology was the most productive journal for gout research. Gout research hotspots have shifted over time in the following order: clinical features, pathological mechanisms, complications, gouty arthritis, epidemiology, and dual-energy computed tomography to drug clinical trials, which can be observed from the keyword analysis and co-cited reference cluster analysis.
    Conclusions: This study found that research on gout is flourishing. The development and experimentation of drugs for the prevention and treatment of gouty arthritis would be the focus of current research and developmental trends in future research.

    Jie Yuan, Qianxi Li, Yanqiang Zhao.
      We conducted a quantitative and qualitative bibliometric analysis based on 8740 research articles from the Web of Science Core Collection published in the last 20 years (2000-2020) for a better understanding of the research progress and development trend of arsenic pollution in freshwater (FAP). The results showed a significant increase in the number of publications from 2007 to 2020, especially after 2015. Four of the top 10 productive authors are from China. Two of the top three research institutions are from China, and the publications of Chinese Academy of Sciences accounted for 5.40% of the total. China is also the center of the national cooperation network, indicating a greater influence of China in this scientific research field. The top three journals included Science of the Total Environmental, Environmental Science Technology, and Journal of Hazardous Materials. Besides arsenic, the high-frequency keywords in this field included adsorption, contamination, groundwater, removal, detection, and geochemistry. The researchers mainly focused on the groundwater environment, as well as the pollution hazards of arsenic in water bodies, remediation techniques, detection, migration, and transformation. Studies should pay more attention to the application and development of phytoremediation technology in the field of FAP in the future.

    A bibliometric and emerging trend analysis on stress granules from 2011 to 2020: A systematic review and bibliometrics analysis.
    Haiyang Yu, Qinhao Chen, Yueyin Pan.
       BACKGROUND: Stress granules (SGs) are the dense granules formed in the cytoplasm of eukaryotic cells in response to stress stimuli, such as endoplasmic reticulum stress, heat shock, hypoxia, and arsenate exposure. Although SGs have been attracting a lot of research attention, there is still a lack of systematic analysis of SGs in the literature.
    METHODS: By analyzing the literature published in the Web of Science database using the R software, we extracted all the information related to SGs from the literature and cited references. The following information was included: publications per year, overall citations, top 10 countries, top 10 authors, co-author collaborations, top 10 institutions, critical areas, and top 10 cited research articles.
    RESULTS: A total of 4052 articles related to SGs were selected and screened. These documents have been cited a total of 110,553 times, with an H-index of 126 and an average of 27.28 citations per article. The authors of the literature included in this study were from 89 different countries/regions. The United States and China had the highest number of publications and ranking institutions.
    CONCLUSIONS: This article presents essential insights on the characteristics and influence of SGs, demonstrating their indispensable role in immune regulation and other fields.

    Bibliometric analysis of the top 100 most-cited articles in neurofibromatosis.
    Nada Alnefaie, Othman T Almutairi, Abdulrahman Y Alturki, Mohammed Bafaquh.
       Background: Neurofibromatosis (NF) is an umbrella term that refers to three distinct disease entities: NF Type 1, Type 2, and schwannomatosis. Here, we reviewed the scientific performance and the most influential publications on NF.
    Methods: A keyword-based search was performed using the Scopus database. The top 100 articles were grouped based on NF types and the studied entities. The differences between the articles, authors, and journals were quantified based on certain parameters. Other parameters were collected for the complete citational analysis.
    Results: The top 100 articles were published between 1961 and 2020. The most trending period of research was in the 1990s and articles studying the clinical aspect and the underlying genetic correlation made up 84% of all articles from the list. The United States of America (USA) had the highest number of contributions (69 articles, 69%). The top institute of contribution to the list was the Howard Hughes Medical Institute, USA (14 articles, 14%). Author-based analysis reveals that the neurologist D. H. Gutmann from St. Louis Children's Hospital, USA, was the most active and authored 11 articles (11%) on the list.
    Conclusion: The publication trends show that articles studying medical and surgical management were of little interest. The top 100 articles did not include any randomized control trials, and the highest level of evidence was obtained from reviews of pooled knowledge as well as population-based and longitudinal studies.

       BACKGROUND: Bibliometric studies are used to analyse and map scientific areas, and study the scientific output and impact of institutes and countries.
    OBJECTIVES: Describe the thematic structure and evolution of the field of physical therapy interventions using articles indexed in Physiotherapy Evidence Database (PEDro). Also, identify and compare the main producers (countries, institutions) over time (research output, citation impact).
    METHODS: Eligible articles were those indexed in PEDro (1986-2017) and matched to Web of Science. VOSviewer software, bibliometric text mining, and visualisation techniques were used to evaluate the thematic structure of the included articles. We collected data about authors' country and institutional affiliation, and calculated bibliometric indicators (production, citation impact).
    RESULTS: A total of 29 090 articles were analysed. Eight topics were identified: "neurological rehabilitation"; "methods"; "exercise for prevention and rehabilitation of lifestyle diseases"; "assessment and treatment of musculoskeletal pain"; "physical activity", "health promotion and behaviour change"; "respiratory physical therapy"; "hospital, primary care and health economics"; "cancer and complementary therapies". The most productive countries were United States, United Kingdom, Australia, and Canada. The most impactful countries were United States, France, Finland, and Canada. The most productive institutions were University of Sydney, VU University of Amsterdam, University of Queensland, and University of Toronto.
    CONCLUSIONS: The thematic structure of physical therapy interventions has evolved over time with "neurological rehabilitation", "methods", "exercise related to lifestyle diseases", and "physical activity" becoming increasingly important. Main producers of this research were traditionally located in North America and Europe but now include countries like China and Brazil.

    A Bibliometric Analysis of Reactive Oxygen Species Based Nanotechnology for Cardiovascular Diseases.
    Yun Liang, Shenjie Liao, Xiaoshen Zhang.
      Cardiovascular diseases (CVDs) continue to be the leading cause of health problems around the world. Because of its unique properties, reactive oxygen species (ROS)-based nanotechnology offers novel solutions to the diagnosis and treatment of CVDs. In order to identify and further promote the development of ROS-based nanotechnology in CVDs, we here provide a bibliometric analysis. 701 eligible articles about the ROS-based nanotechnology for CVD up to May 26th, 2022, were taken from the Web of Science Core Collection database. The VOSviewer was used to analyze annual publications, countries/institutions, funding agencies, journals and research category, and the research hotspots. From the publication of the first article in 2005 to 2021, the output and the number of citations of articles are on the rise. Based on the bibliometric analysis, we found that the current research focuses on the correlation between diagnosis (sensors and), treatment (oxidative stress, inflammation, and drug delivery) and safety (toxicity). Since 2019, research on nanomedicine and drug delivery has become a hotspot. So, more research in chemistry, materials, biology, and medicine is required to further develop and construct ROS-based nanomaterials.

    Gilbert Manuel Schwarz, Stefan Hajdu, Reinhard Windhager, Madeleine Willegger.
       PURPOSE: Hip fractures are one of the most common disabling fractures in elderly people and peri-operative management has advanced considerably over the past decades. The purpose of this study was to evaluate the change of scientific focus by creating a top 50 list of the most influential papers on this topic.
    METHODS: The Clarivate Web of Science Search was used to identify the most cited articles. The used search phrase was [(hip OR pertrochanteric OR (femoral neck)) AND fracture AND (surgery OR treatment)]. The number of citations, citation density, study type, study design, published year, fracture type, country, evidence level and published journal were recorded.
    RESULTS: The top 50 articles were published between 1973 and 2014 and cited between 88 and 496 times. The mean citation density increased noticeably after the year 2000, representing the knowledge gain of the last 20 years. The topics surgical treatment (n = 19), risk factor assessment (n = 19), perioperative hemodynamic management (n = 7), additional treatment (n = 4) and general reviews (n = 1) were covered. Twenty-five articles were published from institutions in Europe, 24 from institutions in North America and one from an institution in Asia.
    CONCLUSION: While studies about surgical treatment options and risk factor assessment have been historically important, there was a rise of articles about additional treatment options for osteoporosis and the optimal postoperative care after the year 2005. The presented lists and map of citation classics give an overview of the most influential studies on hip fractures.

      Mild cognitive impairment (MCI) is a pathological stage between normal cognitive aging and dementia. The blood-brain barrier (BBB) breakdown is emerging as an early biomarker of MCI. This study aimed to visually analyze the literatures related to MCI caused by BBB dysfunction in recent 20 years, systematically identify collaboration networks, track research trends, highlight current hot spots, and predict future frontiers in this field. The related literatures published from 2000 to 2021 were obtained from the Web of Science with the search term "mild cognitive impairment and (blood-brain barrier or neurovascular unit or neurovascular coupling)". VOSviewer software was used to present knowledge map, CiteSpace software was used to extract literature information and make tables, including the top most influential countries, authors, institutions, periodicals, keywords, and references. A total of 333 literatures were used for visual analysis. After 2013, the literatures in the field of BBB dysfunction-induced MCI showed an increased trend in terms of year of publication and quantity of material, with more than 40 publications published each year. USA, England, China, and Sweden cooperated closely. In terms of institutions, Harvard Med Sch ranked first in the number of papers published, followed by Mstricht Univ and Univ Washington. In terms of journals, three of the top five co-cited journals belonged to USA, the other two journals were Neurobiol Aging and J Alzheimers DIS, which were from England and Netherlands respectively. A total of 1752 authors were identified, with Abhay P Sagare the most published and Zlokovic BV the most cited. Keyword emergence detection analysis showed that inflammation, oxidative stress, and memory were new research hot spot in this field. Overall, the research on BBB dysfunction-induced MCI is booming. In the future, cooperation and communication between different countries and institutions should be strengthened.

Cooperation mode, research hotspots, and research frontiers were also analyzed.
    RESULTS: The findings indicate that the number of midwifery research studies have been steadily increasing in China over the last decade. During the study period, Guangdong Province, which received the most research funding, produced the highest number of published articles, followed by Beijing and Shanghai. Research institutions related to midwifery are mainly universities with a strong focus on scientific research. Contemporary topics include core competencies and birth outcomes; research frontiers, including education; competence; and evidence-based practice.
    DISCUSSION: China should accelerate in-depth midwifery research; increase opportunities for regional, institutional, and team cooperation; promote the sublimation of midwifery work from practical experience to disciplinary theory; and provide higher-quality professional services for maternal and child health. Bibliometric analyses may be used to examine midwifery research in other countries too.

      Massive scientific productivity accompanied the COVID-19 pandemic. We evaluated the citation impact of COVID-19 publications relative to all scientific work published in 2020 to 2021 and assessed the impact on scientist citation profiles. Using Scopus data until August 1, 2021, COVID-19 items accounted for 4% of papers published, 20% of citations received to papers published in 2020 to 2021, and >30% of citations received in 36 of the 174 disciplines of science (up to 79.3% in general and internal medicine). Across science, 98 of the 100 most-cited papers published in 2020 to 2021 were related to COVID-19; 110 scientists received ≥10,000 citations for COVID-19 work, but none received ≥10,000 citations for non-COVID-19 work published in 2020 to 2021. For many scientists, citations to their COVID-19 work already accounted for more than half of their total career citation count. Overall, these data show a strong covidization of research citations across science, with major impact on shaping the citation elite.

    Knowledge Mapping of Enterprise Network Research in China: A Visual Analysis Using CiteSpace.
    Wancheng Yang, Shaofeng Wang, Chen Chen, Ho Hon Leung, Qi Zeng, Xin Su.
      Enterprise Network (EN) has increasingly gained popularity in academia. Over the past few decades, a substantial amount of EN studies have been published in China. Drawing upon a sample of 603 papers retrieved from the Chinese Social Sciences Citation Index database (CSSCI) between 1998 and 2020, this study aims to delve into the status quo, knowledge base, research focus, and evolutionary trends of EN research in China. A multifaceted bibliometric analysis was performed using CiteSpace. The findings mainly indicate that the research on EN in China has a clear development context, and the research content gradually changes from macro to micro. In addition to foreign Social Network theories, the research results of domestic scholars have become the basic knowledge in this field. The research includes these topics: the conceptualization of EN, EN as indicators of enterprise development, EN's impact on start-ups, mechanisms of EN's effect and governance of EN. The potential direction for future research has been identified as the integration between EN and other forms of networks, and the structure of EN.

    Randa K Saad, Sara Abu Khudair, Maha El Rabbat, Mayeh Omar, Mohannad Al Nsour, Yousef Khader, Salman Rawaf.
       BACKGROUND: The challenges presented by the COVID-19 pandemic have led to unprecedented global research activity. The Eastern Mediterranean Region (EMR) continues to contribute to COVID-19 research driven by the unique challenges of the region, including the protracted conflicts, already stressed health systems, and serious health and social inequalities.
    OBJECTIVE: This study aims to provide an overview of the publication activities and trends in COVID-19 research in the EMR from the onset of the disease to early 2022 using bibliometric methods.
    METHODS: A literature search using Scopus was conducted from December 1, 2019, to January 31, 2022, using keywords relevant to COVID-19 and the World Health Organization (WHO) EMR country list. Data were exported and analyzed using Microsoft Excel and the Citation Overview function on Scopus. The quality of journals was determined using SCImago Journal Rank and CiteScore. VOSviewer software was used to visualize the relationships between authors, countries, and key terms used in the retrieved documents.
    RESULTS: A total of 6880 documents were retrieved, of which 1805 (26.24%) were from the Kingdom of Saudi Arabia (KSA) and 1782 (25.90%) from Iran, followed by Pakistan, Egypt, and Jordan. Most published documents were affiliated with EMR universities, primarily the Tehran University of Medical Sciences in Iran and King Saud University in KSA (396/6880, 5.76%, and 370/6880, 5.4%, respectively), while only 407 (5.92%) of 6880 documents were associated with universities outside the EMR. For most of the identified publications (5020/6880, 72.97%), no funding source was reported, while King Saud University contributed the largest share (282/1860, 15.16%) of funded publications. Retrieved documents were cited 53,516 times, with an average of 7.78 (SD 34.30). Iran was the EMR country with the most links to other countries (77 links and total link strength of 1279). The 5 authors with the most publications were from KSA, Qatar, and Jordan. There were 290 high-frequency keywords that occurred ≥10 times and were linked in 7 different clusters. The cluster with the most linked keywords was related to epidemiology and mortality. Recent topics included vaccines, vaccination, machine learning, and online learning.
    CONCLUSIONS: This is the first study to show trends in and project future developments of COVID-19 research activity in the EMR. Authors and institutions who led research on COVID-19 in the region were from Iran and KSA. There were multiple regional collaborative efforts; however, international collaboration was limited. Recently, interest has been shifting toward topics related to vaccination, machine learning, and online learning. Understanding the current state of research is instrumental to future research production, and our study will inform regional research initiatives on emerging concepts, as well as opportunities for collaboration and funding.

    Gender Gap in Scientific Publications on COVID-19 in Italy During the First Wave of the Pandemic: An Observational Study.
    Elena Mazzalai, Federica Turatto, Corrado De Vito.
       Background: Worldwide, concerns rise on how COVID-19 pandemic impacted heavily on women, even on those belonging to the scientific community. The Italian scientific production regarding the COVID-19 throughout the first months of the health emergency could help to understand the heft of female researchers in this unique period.
    Objectives: This study aims to investigate the gender gap in the scientific production on COVID-19 in Italy during the first months of the pandemic.
    Methods: A systematic search of the literature was conducted and, for each included study, first and last author's gender, type of study, number of co-authors, type of affiliation, journal's Impact Factor (IF) and specialization were extracted. Descriptive and univariate analyses were performed.
    Results: 22.2% of the articles were signed by a woman as first author, 18.1% as last authors. Female authorship was less frequent than male authorship regardless of the type of study, number of co-authors, type of affiliation and field of specialization.
    Conclusion: This analysis reveal a low prevalence of studies with a female first or last author and suggests that the low share of female authors publishing on COVID-19 during the considered timespan is a transversal issue throughout the Italian medical field.

    Rasha Atlasi, Aboozar Ramezani, Ozra Tabatabaei-Malazy, Sudabeh Alatab, Vahideh Oveissi, Bagher Larijani.
       Objective: Many studies have suggested herbal medicines as alternatives or adjuvants to modern drugs for COVID-19. Their scientometric analyses can provide a scientific overview of this topic.
    Materials and methods: Web of Science (WOS) and Scopus were searched for articles on the use of herbal medicines in COVID-19 published until 26 October 2020. Collected data were analyzed for document type, subject area, top journal, citation number, and authors' collaboration network using VOSviewer 1.6.15, ScientoPy 2.0.3, Gephi 0.9.2, and SPSS 15 statistical tools.
    Results: After screening the 3185 retrieved records, 378 and 849 records, respectively from WOS and Scopus, remained for quantity analysis. Original and review articles were the two main types of papers in both databases. Top subject areas were drug and medicine, respectively in the WOS and Scopus databases. The top three productive countries in the field were China, the US, and India. The most cited article was a practice guideline in both databases. "Journal of Biomolecular Structure Dynamics" in WOS and "Chinese Traditional and Herbal Drugs" in Scopus were the top journals. Top keywords included "COVID-19″ and "Traditional Chinese Medicine". US authors had the highest collaboration with other authors.
    Conclusions: The current study provides a snapshot of the quantity and characteristics of published scholarly documents in recent months in the intersection of herbal medicines and COVID-19. Our findings help scientists to find the existing gaps, identify the active authors and scientific institutes to collaborate with and use their experience to produce new knowledge in the future.

    Utilizing Data from Wearable Technologies In the Era of Telemedicine to Assess Patient Function and Outcomes in Neurosurgery: Systematic Review and Time-Trend Analysis of the Literature.
    William Mualem, Sulaman Durrani, Nikita Lakomkin, Jamie Van Gompel, Alfredo Quiñones-Hinojosa, Mohamad Bydon.
       INTRODUCTION: The COVID-19 pandemic has driven the increased use of telemedicine and the adoption of wearable technology in neurosurgery. We reviewed studies exploring use of wearables on neurosurgical patients and analyzed wearables' scientific production trends.
    METHODS: The review encompassed PubMed, EMBASE, Web of Science, and Cochrane Library. Bibliometric analysis was performed using citation data of the included studies through Elsevier's Scopus database. Linear regression was utilized to understand scientific production trends. All analyses were performed on R 4.1.2.
    RESULTS: We identified 979 studies. After screening, 49 studies were included. Most studies evaluated wearable technology use for patients with spinal pathology (n=31). The studies were published in a 24-year period (1998-2021). Forty-seven studies involved wearable device-use relevant to telemedicine. Bibliometric analysis revealed a compounded annual growth rate (CAGR) of 7.3%, adjusted for inflation, in annual scientific production from 1998 to 2021 (coefficient=1.3; 95% C.I. = [0.7, 1.9], p<0.01). Scientific production steadily increased in 2014 (n=1) and peaked from 2019 (n=8) to 2021 (n=13) in correlation with the COVID-19 pandemic. Publications spanned 34 journals, averaged 24.4 citations per article, 3.0 citations per year per article, and 8.3 authors per article.
    CONCLUSION: Wearables can provide clinicians with objective measurements to determine patient function and quality of life. The rise in articles related to wearables in neurosurgery demonstrates the increased adoption of wearable devices during the COVID-19 pandemic. Wearable devices appear to be a key component in this era of telemedicine and their positive utility and practicality are increasingly being realized in neurosurgery.

    [Visual analysis on regulation of necroptosis with Chinese medicine based on VOSviewer and CiteSpace knowledge graphs].
    Jing-Jing Yang, Yi-Hui Deng, Yu-Zhe Cai, Xiang-Yu Chen, Ding-Xiang Li.
      The study was conducted by searching the literature related to the regulation of necroptosis with Chinese medicine from January 1, 2005 to December 31, 2021 in CNKI, VIP, Wanfang, Web of Science(WoS), and PubMed. The obtained literature were imported into NoteExpress for eliminating duplicates and screening, and the final included articles were imported into Excel to plot the publication trend. The core authors were identified according to Price's law, and VOSviewer 1.6.17 was used to draw a collaborative view of the core authors and sort the high-frequency keywords. Then CiteSpace 5.8.R3 was employed to analyze keywords clustering, burst, and timeline view. Finally, 98 Chinese articles and 72 English articles were included in the study. The number of publications on the regulation of necroptosis with Chinese medicine has been increasing year by year. China ranked among the top in the world in terms of the number of publications, and Chinese authors played a central role in this field. Specifically, LIU Hua published the most Chinese literature while CHEN X P had the most English publications. The collaborative view of the core authors showed more intra-team cooperation and less inter-team cooperation. The Chinese and English keywords formed ten clusters separately, indicating that the research hotspots of regulation of necroptosis with Chinese medicine mainly focused on disease, prescription, related factors, and mecha-nism. Further, the analysis of Chinese and English keywords revealed that regarding disease treatment, tumor, ischemia-reperfusion injury, neurodegenerative diseases, and inflammatory diseases were studied most. The Chinese medicines that received much attention in this field were curcumin, shikonin and tanshinone. The main protein factors involved were Ripk1, Ripk3, Mlkl, and TNF-α, and Ripk1/Ripk3/Mlkl and p53 signaling pathways were predominant. Moreover, single herbs and herbal monomers were the hotspots of the included articles. In the future, scholars need to expand the study of classical Chinese herbal compounds and explore their mechanism of action in the occurrence and development of various diseases, to provide new ideas and experimental basis for the treatment of clinical diseases with Chinese medicine.

    A Scientometric Visualization Analysis for Molecular Mechanisms of Substance Abuse and Its Neurotoxicity From 1997 to 2021.
    Aijia Zhang, Zilong Liu, Man Liang.
      Substance abuse has become a global problem due to drug-induced addiction and neurotoxicity, which causes a huge physical, social, and financial burden. Various kinds of drugs can hijack the users'/abusers' behavior and associated neurocircuitry. To summarize recent scientific advances on drug abuse, we reviewed relevant publications to analyze research progress and such trends through bibliometric ways. Based on retrieval strategies, a total of 681 scientific records published from 1997 to 2021 were screened and included in the Web of Science (WoS) database. Further scientometric analysis revealed that annual publication output increased across this period, with the United States of America (USA) contributing a significant number of reasons. Research has focused on neurotransmitter, oxidative stress, mitochondrial system injury, and other neurotoxic mechanisms. Neuroimmune, neurotoxic targets, and new psychoactive substances have been hot topics in recent years, which deserve continued research in the future. Specific research on molecular mechanisms has progressed across this period, with an emphasis on the root cause of toxicity and molecular targets for therapy. Moreover, collaborations of international multi-disciplinary research teams have been efficient and need to be encouraged for addiction research and the development of appropriate therapeutic processes.

    Academic benchmark of highly influential ophthalmologists listed in the ophthalmology power list.
    Rachel Shemesh, Alon Tiosano, Edward Barayev, Elchanan Zloczower, Assaf Gershoni, Gad Dotan.
       OBJECTIVE: To review the academic benchmark of highly influential ophthalmologists listed in the ophthalmology '2020 Power List'.
    METHODS: In this cross-sectional study, the academic profiles, achievements, and bibliometric profiles of all ophthalmologists listed in the 'Power List of 2020', regarded as the most influential figures in ophthalmology today, were analysed.
    RESULTS: Ninety-five ophthalmologists were studied, after excluding 10 non-ophthalmologist figures that are also listed. Their mean age is 63 ± 11.7 years, with a strong male predominance (84.2%, n = 80 males, P < 0.001). All have a medical doctorate degree, and 31% (n = 29) have a Philosophy Doctor (PhD) degree. Fifty-three percent (n = 51) are graduates of medical schools in the United States (US). However, non-US ophthalmologists have a higher percentage of PhD degrees (41%, 18/44) vs. US ophthalmologists (22%, 11/51, P = 0.069), and also a longer duration of post-residency training (5.8 ± 3.1 vs. 1.8 ± 0.9 years, P < 0.001). The most common subspecialty was cataract and anterior segment surgery (42%, n = 40). The mean and standard deviation of the total number of papers published by ophthalmologists were 307.4 ± 226.3, with a mean citation record of 11,835.7 ± 13,330.5, and a mean h-index of 46.9 ± 27.9.
    CONCLUSIONS: The ophthalmologists listed on the 'Power List of 2020' are leaders with high accomplishments and an established interest in research evidenced by a high record of publications and an exceptional bibliometric profile. The list contains more US figures with a gender disparity, demonstrating a greater difficulty for international ophthalmologists, especially women, in achieving this high level of recognition.

    Depicting Developing Trend and Core Knowledge of Primary Open-Angle Glaucoma: A Bibliometric and Visualized Analysis.
    Liting Zhao, Jinfei Li, Lemeng Feng, Cheng Zhang, Wulong Zhang, Chao Wang, Ye He, Dan Wen, Weitao Song.
       Objective: The prevalence of glaucoma is rising due to an increasing aging population. Because of its insidious and irreversible nature, glaucoma has gradually become the focus of attention. We assessed primary open angle glaucoma, the most common type of glaucoma, to study its present status, global trend, and state of clinical research.
    Methods: Publications from 2000 to 2021 in Web of Science database were retrieved and analyzed by bibliometrics. VOSviewer and Citespace were used for analysis.
    Results: A total of 6,401 publications were included in this review, and we found that the number of publications increased from 139 in 2000 to 563 in 2021. American researchers have published the most papers and had the highest h-index and the most citations, while the Journal of Glaucoma has published the most papers on this topic. Some key researchers, contributing institutions, their partnerships, and scientific masterpieces were identified. The publications we reviewed fall into seven categories: publications on intraocular pressure, normal tension glaucoma, risk factors, the trabecular meshwork, optical coherence tomography, surgery, and mutation. Clear study hotspots were described, which began with epidemiology and transitioned to pathogenesis and diagnosis and then to treatment.
    Conclusion: Studies on primary open angle glaucoma extend well beyond ophthalmology to biochemistry molecular biology, general internal medicine, pharmacology, pharmacy, science technology, and other areas. Interest, research and publications on primary open angle glaucoma are on the rise.

    Assessing the gender gap in musculoskeletal radiology authorship across three continents: are really the "ladies first"?
    N Nischal, K P Iyengar, R Vaishya, S Haleem, E Zaw Pe, H N Choudur, R Botchu.
       AIM: To assess gender-specific authorship trends in musculoskeletal (MSK) radiology in three major radiology journals, Skeletal Radiology (SR), Clinical Radiology (CR) and Indian Journal of Radiology and Imaging (IJRI).
    MATERIALS AND METHODS: Retrospective analysis of articles pertaining to MSK radiology was done for the years 2000, 2010, and 2020 for SR and CR and for the years 2010 and 2020 for IJRI. The number and positions of female authors was noted.
    RESULTS: Three hundred and twenty-five articles were reviewed after excluding the articles where the gender of one or more authors could not be conclusively determined. In SR, the percentage of female authors increased significantly from 4% in 2000 to 17% in 2010 (p<0.0001) and to 21.9% in 2020 (p<0.0001) with an increase in the percentage of first female authors from 0.8% in 2000 to 4.9% in 2010 and further to 5.4% in 2020. In CR, the percentage of female authors reduced from 13.8% in 2000 to 13.6% in 2010 (p=0.9798 and further reduced to 7% in 2020 (p=0.1592). In IJRI, the percentage of articles with no female authors went down from 36.4% (2010) to 26.7% (2020).
    CONCLUSION: There is an upward trend in female authorship in MSK radiology related articles in SR and IJRI with continued under-representation in CR. The first and middle order female authors have shown a significant increase, although the number of last female authors remains very low. Analysis of such trends in academic journals from other subspecialities in medicine needs to be undertaken to confirm or refute the findings of this study.

    Representation of women as editors in andrology journals.
    Ming Wang, Yan Xue, Menghong Wei, Hui Jiang, Xiansheng Zhang.
       BACKGROUND: Surveys of gender diversity in editorial boards of journals have been conducted in several disciplines, but not in andrology.
    OBJECTIVES: The present study was designed to investigate the gender distribution of editorial boards of andrology journals.
    METHODS: A total of eight andrology journals were included in the study, and the gender information and geographical location of editors were identified based on the information obtained from the Internet.
    RESULTS: A total of 382 editors' gender information was confirmed. Women made up 1 of the 9 editors-in-chief (11.1%), 13 of the 68 deputy/associate editors (19.1%), 37 of the 270 editorial/advisory board members (13.7%) and 0 of the 35 other types of editors (0%). There was no significant difference in the journal impact factor between male and female editors-in-chief (3.060±1.274 vs 3.482, p = 0.156), and no significant association was found between impact factor and the proportion of female editor (Spearman's r = -0.204, P = 0.629).
    DISCUSSION AND CONCLUSION: Andrology-related journals lacked adequate gender diversity, not all journals reserved reasonable editorial positions for women. Besides, increased impact factor did not bring additional gender bias. Women should be given more reasonable seats to improve gender diversity in andrology-related journals.

    [Scoping review of domestic and overseas hospital-based health technology assessment].
    Si-Min Xu, Ze-Qi Dai, Xue Wu, Miao-Miao Li, Xing Liao.
      This paper systematically sorted out the related research on hospital-based health technology assessment(HB-HTA) and clarified the research status of this field to provide a basis for the future research direction and focus of HTA in traditional Chinese medicine(TCM) hospitals. Based on the scoping review, relevant research papers were retrieved from Chinese databases(including CNKI, Wanfang, VIP, and SinoMed) and PubMed and analyzed. Among the included 99 papers, the earliest one was published in 2005 in China, and the number of papers has been increasing since 2016. In terms of journals, the included papers were published in 39 journals, including 24 core ones and 2 SCI ones. In terms of the number of publications, the Chinese Journal of Evidence-Based Medicine accounted for the majority(n=6). Among the 175 authors involved, three of them published 15 papers, respectively, accounting for 20.83% and ranking the top, and they came from Renmin University of China and the National Health Commission of China. There were 38 first units dominated by hospitals. Hebei General Hospital published the most papers(n=10), followed by Renmin University of China(n=9) and the National Health Commission of China(n=7). In terms of research type, the research papers were dominated by evaluation and practice ones(n=29), followed by reviews(n=20). In terms of research topic, the research was mainly carried out from devices(n=26) and macro-perspective scope(n=24). Half of the research in China was funded. For 27 research papers published abroad, the number of publications in the past five years was small, with 16 countries involved. Developed countries paid more attention to this field than developing countries. Especially in Europe and the US, the publishing institutions were mainly universities, and the types of research were mainly interviews and evaluation or practice. In recent years, the attention of HB-HTA in China has been increasing year by year, and the development of related projects has provided a scientific decision-making basis for the admission and management of new technologies in hospitals in China. However, there are few researchers and institutions in this field, and the research scope is small. In the future, more investment is needed to encourage more hospitals, especially TCM hospitals, to carry out HB-HTA, explore the HB-HTA system suitable for Chinese conditions, and improve the scientific decision-making of hospitals.

    Graphdiyne applications in sensors: A bibliometric analysis and literature review.
    Xiaolong Li, Yuhong Zheng, Weihong Wu, Meiqing Jin, Qingwei Zhou, Li Fu, Najmeh Zare, Fatemeh Karimi, Majid Moghadam.
      Graphdiyne is a two-dimensional carbon nanomaterial synthesized artificially in 2010. Its outstanding performance is considered to have great potential in different fields. This article summarizes the work of graphdiyne in the sensing field by literature summary and bibliometrics analysis. The development of graphdiyne in the field of sensing has gone through a process from theoretical calculation to experimental verification. Especially in the last three years, there has been very rapid development. The theoretical calculations suggest that graphdiyne is an excellent gas sensing material, but there is little experimental evidence in this direction. On the contrary, graphdiyne has been widely reported in the field of electrochemical sensing. At the same time, graphdiyne can also be used as a molecular switch for DNA sequencing. Fluorescent sensors based on graphdiyne have also been reported. In general, the potential of graphdiyne in sensing still needs to be explored. Current research results do not show that graphdiyne has irreplaceable advantages in sensing. The bibliometric analysis used in this review also provides cooperative network analysis and co-citation analysis on this topic. This provides a reference for the audience wishing to undertake research on the topic. In addition, according to the analysis, we also listed the direction that which this field deserves attention in the future.

    Progress and Prospects of Research on Public Services in Sports in China: Analysis in the Context of Bibliometric Ecological Civilization and Social Networks.
    Xiang Zhong, Chao Jiang, Li Li, Haikui Zhou.
      In order to better understand the current situation of Chinese public sports, this paper studies Chinese public sports. According to SATI3.2 statistics, 71 newsletters have published a total of 903 articles, of which 40 newsletters have one article, 19.7% of the newsletters have 2-9 books, and 17 magazines have more than 10 issues. The results show that by measuring data, we can better understand the current state of China's public services. This paper uses the method of bibliometric analysis to sort out and summarize the policies, characteristics, hotspots, and trends of China's public service field under the social network environment. The survey shows that the education sector has paid less for public entertainment in recent years. The research direction is system, equity, government procurement, interest, capital allocation, strategy, and supply chain. This paper highlights that the shortcomings of public sports research in our country: "public sports services" and "public sports services" are not integrated; there are many macrostudies on public service sports but few microstudies; there is no track and field research for special public groups. This paper puts forward research guidance for China's public sports services and, at the same time, strengthens the research on public services of different products of rural sports development, strengthens the research on the intelligence of sports public services, and strengthens the research on the role of public sports. Governments at all levels support and strengthen research on public sports service standards, strengthen research on public sports performance measurement measures, and strengthen public sports balance research.

    A systematic analysis of preprints in Trauma & Orthopaedic surgery.
    Sandro Hodel, Farah Selman, Sylvano Mania, Steven M Maurer, Christoph J Laux, Mazda Farshad.
       AIMS: Preprint servers allow authors to publish full-text manuscripts or interim findings prior to undergoing peer review. Several preprint servers have extended their services to biological sciences, clinical research, and medicine. The purpose of this study was to systematically identify and analyze all articles related to Trauma & Orthopaedic (T&O) surgery published in five medical preprint servers, and to investigate the factors that influence the subsequent rate of publication in a peer-reviewed journal.
    METHODS: All preprints covering T&O surgery were systematically searched in five medical preprint servers (medRxiv, OSF Preprints, Preprints.org, PeerJ, and Research Square) and subsequently identified after a minimum of 12 months by searching for the title, keywords, and corresponding author in Google Scholar, PubMed, Scopus, Embase, Cochrane, and the Web of Science. Subsequent publication of a work was defined as publication in a peer-reviewed indexed journal. The rate of publication and time to peer-reviewed publication were assessed. Differences in definitive publication rates of preprints according to geographical origin and level of evidence were analyzed.
    RESULTS: The number of preprints increased from 2014 to 2020 (p < 0.001). A total of 38.6% of the identified preprints (n = 331) were published in a peer-reviewed indexed journal after a mean time of 8.7 months (SD 5.4 (1 to 27)). The highest proportion of missing subsequent publications was in the preprints originating from Africa, Asia/Middle East, and South America, or in those that covered clinical research with a lower level of evidence (p < 0.001).
    CONCLUSION: Preprints are being published in increasing numbers in T&O surgery. Depending on the geographical origin and level of evidence, almost two-thirds of preprints are not subsequently published in a peer-reviewed indexed journal after one year. This raises major concerns regarding the dissemination and persistence of potentially wrong scientific work that bypasses peer review, and the orthopaedic community should discuss appropriate preventive measures.Cite this article: Bone Jt Open 2022;3(7):582-588.

    Research and academic output evaluation for career initiation or progression: Critical issues for Health Professionals.
    Neeta Kumar, Ruchika Gupta, Sanjay Gupta.
      In current times, much stress is being laid on the evaluation of research productivity of researchers or faculty in addition to the academic qualifications and experience for the purposes of recruitment, promotion, and research grant funding. Over the years, several quantitative indices have been devised for this purpose. Some of these indices such as h-index, impact factor and e-index are being extensively used by research organizations, universities, accreditation bodies and funding agencies for basic scientists as well as health professionals. In the absence of any formal training, these parameters or their advantages and shortcomings may not be well understood by the health professionals, especially in the early stages of their careers and sometimes, even by the evaluators. A big unanswered question is the validity of the same criteria for health professionals as are applicable for the basic science researchers. Since health professional undertaking research assignments are neither adequately trained in basic research nor can they comprehend these indices well, the same yardstick to evaluate these two widely different groups of researchers often places the health professionals at a disadvantage.This paper aims to highlight certain vital issues related to the application of research productivity indicators for recruitment and career progression of health care professionals.

    Metrics to evaluate implementation scientists in the USA: what matters most?
    Brenna B Maddox, Mary L Phan, Y Vivian Byeon, Courtney Benjamin Wolk, Rebecca E Stewart, Byron J Powell, Kelsie H Okamura, Melanie Pellecchia, Emily M Becker-Haimes, David A Asch, Rinad S Beidas.
       BACKGROUND: Implementation science has grown rapidly as a discipline over the past two decades. An examination of how publication patterns and other scholarly activities of implementation scientists are weighted in the tenure and promotion process is needed given the unique and applied focus of the field.
    METHODS: We surveyed implementation scientists (mostly from the USA) to understand their perspectives on the following matters: (1) factors weighted in tenure and promotion for implementation scientists, (2) how important these factors are for success as an implementation scientist, (3) how impact is defined for implementation scientists, (4) top journals in implementation science, and (5) how these journals are perceived with regard to their prestige. We calculated univariate descriptive statistics for all quantitative data, and we used Wilcoxon signed-rank tests to compare the participants' ratings of various factors. We analyzed open-ended qualitative responses using content analysis.
    RESULTS: One hundred thirty-two implementation scientists completed the survey (response rate = 28.9%). Four factors were rated as more important for tenure and promotion decisions: number of publications, quality of publication outlets, success in obtaining external funding, and record of excellence in teaching. Six factors were rated as more important for overall success as an implementation scientist: presentations at professional meetings, involvement in professional service, impact of the implementation scientist's scholarship on the local community and/or state, impact of the implementation scientist's scholarship on the research community, the number and quality of the implementation scientist's community partnerships, and the implementation scientist's ability to disseminate their work to non-research audiences. Participants most frequently defined and described impact as changing practice and/or policy. This expert cohort identified Implementation Science as the top journal in the field.
    CONCLUSIONS: Overall, there was a significant mismatch between the factors experts identified as being important to academic success (e.g., tenure and promotion) and the factors needed to be a successful implementation scientist. Findings have important implications for capacity building, although they are largely reflective of the promotion and tenure process in the USA.

    Land quality evaluation for sustainable development goals: a structured review using bibliometric and social network analysis.
    Tam Minh Pham, Giang Thi Huong Dang, Bora Ju, Trung Trong Nguyen.
      This literature review focuses on land quality evaluation (LQE) and its effects on sustainable development through quantitative analysis and value-added information. In contrast to the traditional perspective, a structured review based on bibliometric indicators and social network analysis allows identifying hidden evidence for answering the following research questions: (i) What: What is the application of LQE? (ii) Which: Which sustainable development goals does the application contribute to? (iii) Why and how: What are the main applications and methods of each topic? (iv) Where: Where is the hotspot of the problem? What is the future research orientation of the topic? (v) How and when: How has the topic grown since 2000? Data investigation explores 4029 articles in 2000-2019 from four publishers. With the support of VOSviewer software, six clusters corresponding to six main applications of LQE are classified. Overlapping keywords in several clusters are resolved by the binary term frequency counter for the cluster preference determination. After conducting the data verification and editing process, a structured review is performed again with systematic research questions. This research offers a synthesis of traditional and novel quantitative analysis for literature review, which is comprehensive, accurate, and reliable.

    Lipoprotein(a) in Cardiovascular Diseases: Insight From a Bibliometric Study.
    David Šuran, Helena Blažun Vošner, Jernej Završnik, Peter Kokol, Andreja Sinkovič, Vojko Kanič, Marko Kokol, Franjo Naji, Tadej Završnik.
      Lipoprotein(a) [Lp(a)] is a complex polymorphic lipoprotein comprised of a low-density lipoprotein particle with one molecule of apolipoprotein B100 and an additional apolipoprotein(a) connected through a disulfide bond. The serum concentration is mostly genetically determined and only modestly influenced by diet and other lifestyle modifications. In recent years it has garnered increasing attention due to its causal role in pre-mature atherosclerotic cardiovascular disease and calcific aortic valve stenosis, while novel effective therapeutic options are emerging [apolipoprotein(a) antisense oligonucleotides and ribonucleic acid interference therapy]. Bibliometric descriptive analysis and mapping of the research literature were made using Scopus built-in services. We focused on the distribution of documents, literature production dynamics, most prolific source titles, institutions, and countries. Additionally, we identified historical and influential papers using Reference Publication Year Spectrography (RPYS) and the CRExplorer software. An analysis of author keywords showed that Lp(a) was most intensively studied regarding inflammation, atherosclerosis, cardiovascular risk assessment, treatment options, and hormonal changes in post-menopausal women. The results provide a comprehensive view of the current Lp(a)-related literature with a specific interest in its role in calcific aortic valve stenosis and potential emerging pharmacological interventions. It will help the reader understand broader aspects of Lp(a) research and its translation into clinical practice.

    Language and communication in international students' adaptation: a bibliometric and content analysis review.
    Michał Wilczewski, Ilan Alon.
      This article systematically reviews the literature (313 articles) on language and communication in international students' cross-cultural adaptation in institutions of higher education for 1994-2021. We used bibliometric analysis to identify the most impactful journals and articles, and the intellectual structure of the field. We used content analysis to synthesize the results within each research stream and suggest future research directions. We established two major research streams: second-language proficiency and interactions in the host country. We found inconclusive results about the role of communication with co-nationals in students' adaptation, which contradicts the major adaptation theories. New contextualized research and the use of other theories could help explain the contradictory results and develop the existing theories. Our review suggests the need to theoretically refine the interrelationships between the interactional variables and different adaptation domains. Moreover, to create a better fit between the empirical data and the adaptation models, research should test the mediating effects of second-language proficiency and the willingness to communicate with locals. Finally, research should focus on students in non-Anglophone countries and explore the effects of remote communication in online learning on students' adaptation. We document the intellectual structure of the research on the role of language and communication in international students' adaptation and suggest a future research agenda.

    Academic Output in Global Surgery after the Lancet Commission on Global Surgery: A Scoping Review.
    Zachary Fowler, Rohini Dutta, John L Kilgallon, Adili Wobenjo, Soham Bandyopadhyay, Priyansh Shah, Samarvir Jain, Nakul P Raykar, Nobhojit Roy.
       BACKGROUND: The Lancet Commission on Global Surgery (LCoGS) published its seminal report in 2015, carving a niche for global surgery academia. Six years after the LCoGS, a scoping review was conducted to see how the term 'global surgery' is characterized by the literature and how it relates to LCoGS and its domains.
    METHODS: PubMed was searched for publications between January 2015 and February 2021 that used the term 'global surgery' in the title, abstract, or key words or cited the LCoGS. Variables extracted included LCoGS domains, authorship metrics, geographic scope, and clinical specialty.
    RESULTS: The search captured 938 articles that qualified for data extraction. Nearly 80% of first and last authors had high-income country affiliations. Africa was the most frequently investigated region, though many countries within the region were under-represented. The World Journal of Surgery was the most frequent journal, publishing 13.9% of all articles. General surgery, pediatric surgery, and neurosurgery were the most represented specialties. Of the LCoGS domains, healthcare delivery and management were the most studied, while economics and financing were the least studied.
    CONCLUSION: A lack of consensus on the definition of global surgery remains. Additional research is needed in economics and financing, while obstetrics and trauma are under-represented in literature using the term 'global surgery'. Efforts in academic global surgery must give a voice to those carrying the global surgery agenda forward on the frontlines. Focusing on research capacity-building and encouraging contribution by local partners will lead to a stronger, more cohesive global surgery community.

    [The independent research on rare diseases financed by the Italian Medicines Agency.]
    Patrizia Marconi, Carmela Zappalà, Alessia Lofaro, Sara Maiolino, Chiara Mastellone, Maurizio Belfiglio.
       INTRODUCTION: Rare diseases have a high social and health impact. Since 2005, AIFA has been funding independent clinical research. The objective of this paper is to describe data on independent research on rare diseases financed by the Agency.
    METHODS: With reference to studies financed by AIFA between 2005-2018 the following data have been collected: financial characteristics, study design, therapeutic area, population included, completion status, availability of study results publications, publication characteristics and conclusions. Data have been analyzed in order to provide information on characteristics and scientific productivity of clinical studies on rare diseases.
    RESULTS: Between 2005 and 2018, AIFA published 9 Calls for Funding of Independent Research and financed 282 clinical studies, 111 (about 40%) of which were on a rare disease and/or a rare tumor for a total of € 43,455,438. Studies were interventistic in 93.6% (mainly phase II or III). The most represented therapeutic area was oncology (19.9%), followed by neurology (17.1%), and onco-hematology (16.2%). 28.8% of clinical studies enrolled fragile population (children, elderly, pregnant women). Fourty eight studies (43.2%) completed according to protocol, 8 (7.2%) completed with reduced sample size, 18 (16.2%) were prematurely terminated, while 37 of them are still ongoing. In the subgroup of 74 closed studies at least a scientific publication is available for 49 of them. A total of 81 papers are available including two publications related to ongoing studies (range 1-8; mean 1.5; median 1). Cumulative Impact Factor is 619.269 (range for single paper 0.17-34.492).
    DISCUSSION: A good percentage of clinical studies financed by AIFA were on rare diseases and/or rare tumors. Clinical trials were less likely to complete according to protocol than observational ones, in agreement with literature data; on the other hand once completed, clinical trials were more likely to publish research findings. Overall, 66.2% of closed studies has at least one publication; this percentage is higher if we consider the subgroup of clinical trials and if we consider clinical trials completed according to study protocol (95.3%).

    Descriptive Analysis of Cornea and Anterior Segment Fellowship Program Directors in 2020.
    Sophia S Lam, Kartik Garg, Wesam S Shalaby, Christopher J Rapuano, Zeba A Syed.
       PURPOSE: To investigate demographic characteristics, educational backgrounds, and academic achievements among program directors (PDs) of Cornea and External Disease and Anterior Segment fellowships in the United States in 2020.
    SETTING: N/A.
    DESIGN: Cross-sectional study.
    METHODS: PDs of Cornea and External Disease and Anterior Segment fellowships were identified using the San Francisco Match website. Fellowship program features reviewed included academic or private practice type, number of cornea faculty, and sex of chairperson. PD demographic characteristics, educational and training background, and academic productivity were analyzed using publicly available profiles and databases.
    RESULTS: 76 Cornea and External Disease and 10 Anterior Segment fellowships were reviewed. Of 86 reviewed programs, 55 (64.0%) were considered academic, 30 (34.9%) were private practice, and 1 (1.2%) was hybrid. 76 Cornea and External Disease PDs and 12 Anterior Segment PDs were identified. Overall, 21 (23.9%) of PDs were women and the mean age for all PDs was 52.6±11.5 years. Of the 88 PDs, the average number of publications was 45.1±55.9. Mean h-index was 16.7±15.4 and was higher among Cornea and External Disease than Anterior Segment PDs (18.2±15.5 vs. 7.1±11.4, p=0.008) and also higher among academic than private practice PDs (19.9±15.1 vs. 11.2±14.7, p=0.011). More female PDs were in departments with a female chairperson compared to male PDs [6 (28.6%) vs. 4 (6.0%), p=0.011].
    CONCLUSIONS: Cornea and External Disease and Anterior Segment fellowship PDs represent a wide array of backgrounds and scholarly achievements. Female PDs remain in the minority and are more common in departments with female chairpersons.

    Disparity in Female and Asian Representation Amongst Cardiology Journal Editorial Boards Members: A Call for Empowerment.
    Oliver Z H Lim, Yundai Chen, Stefanie Dimmeler, Anthony W J Yong, Harpreet Singh, Maegan L E Sim, Gwyneth Kong, Wen Hui Lim, Ting Ting Low, Duk-Woo Park, Nicholas W S Chew, Roger Foo.
       BACKGROUND: While progress is evident in gender and ethnic representation in the workplace, this disparity remains prevalent in academic positions.
    OBJECTIVES: We examined gender and Asian ethnic representation in editorial boards of cardiology journals.
    METHODS: A cross-sectional analysis was conducted using publicly available data on Cardiology and Cardiovascular medicine journals in first quartile of the 2020 Scimago Journal & Country Rank indicator. The proportions of female and Asian editorial board members, associate editors and editors-in-chief were assessed. Subgroup analyses were conducted based on the journal's geographical origin, subspecialty, and demographic of the editor-in-chief.
    RESULTS: Seventy-six cardiology journals, involving 8915 editorial board members, were included. Only 19.6% of editorial board members were female, 20.8% Asians, and 4.0% Asian females. There were less female representation amongst editors-in-chief (9.9%) compared to associate editors (22.3%). European (18.1%) and North American-based journals (21.1%) had higher female representation compared to Asian-based journals (8.7%). There was lower Asian representation in European (18.1%) and North American-based journals (19.9%) compared to Asian-based journals (72.3%). Females were underrepresented in interventional (14.5%) journals, while Asians were underrepresented in general cardiology (18.3%) and heart failure (18.3%) journals. Journals led by female editors-in-chief had significantly higher female representation compared to male-led ones, while journals with Asian editors-in-chief had greater Asian representation compared to non-Asian led ones.
    CONCLUSION: This study highlights the female and Asian ethnic underrepresentation in academic roles in cardiology journal editorial boards. Further analysis is needed for other ethnicities, while the community pushes towards gender-balanced and ethnic diversity across editorial boards.

    Business trends & challenges in Islamic FinTech: A systematic literature review.
    Hatim Dawood, Dr Fatin Al Zadjali, Mohammed Al Rawahi, Dr Sitara Karim, Dr Mohamed Hazik.
      Background: This systematic literature review (SLR) study is on Islamic financial technology (FinTech) business trends and challenges. It follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. This research identifies the gaps in Islamic FinTech, which require further studies. Moreover, it highlights the issues raised during the coronavirus disease 2019 (COVID-19) pandemic. Methods: This study is based on the FinTech business model (BM) classifications by Lee & Shin and Imerman & Fabozzi. Furthermore, the set of challenges used in this study are adopted from research by Lee & Shin and Li & Xu. The Scopus database was used to collect data using nine keywords. Articles and review papers published between 2016 and 2022 were included. Studies that were not published in English, and those with no ranking journals were excluded. The results were presented using bibliometric analysis. Results: The results showed 36 articles discussing Islamic FinTech business trends and challenges, and most of these studies are conducted on FinTech crowdfunding vertical BM. By contrast, the most dominant horizontal BMs are FinTech regulation and FinTech funding BMs. The top challenge found in this study is the regulation management challenges. Moreover, there are remarkable dominating articles and reviews published in 2020 and 2021 discussing COVID-19. Conclusions: This study concluded that many horizontal BMs were not covered in Islamic FinTech, especially horizontal technology BMs. Investment, property and insurance BMs are examples of unavailable articles. Islamic FinTech is considered a promising field due to the size of the opportunities it presents, the available capital, and the great demand for banking and financial products that comply with the Sharia. This study will help the Islamic FinTech industry grow and predict the demand, and provide an alternative to conventional banking FinTech and further boost the technology progress in the financial industry.

    Under-representation of female athletes in research informing influential concussion consensus and position statements: an evidence review and synthesis.
    Christopher D'Lauro, Emily Ruth Jones, Lily Mc Swope, Melissa N Anderson, Steven Broglio, Julianne D Schmidt.
       OBJECTIVE: We aimed to quantify the female athlete composition of the research data informing the most influential consensus and position statements in treating sports-related concussions.
    DESIGN: We identified the most influential concussion consensus and position statements through citation and documented clinician use; then, we analysed the percentage of male and female athletes from each statement's cited research.
    DATA SOURCES: We searched PubMed on 26 August 2021 with no date restrictions for English language studies using the terms 'concussion position statement' and 'concussion consensus statement.'
    ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Based on each statement having multiple statement editions, documented clinician use, and substantial citation advantages, we selected the National Athletic Trainers' Association (NATA, 2014), International Conference on Concussion in Sport (ICCS, 2017) and the American Medical Society for Sports Medicine (AMSSM, 2019). We extracted all cited studies from all three papers for assessment. For each paper analysing human data, at least two authors independently recorded female athlete participant data.
    RESULTS: A total of 171 distinct studies with human participants were cited by these three consensus and position papers and included in the female athlete analyses (93 NATA; 13 ICCS; 65 AMSSM). All three statements documented a significant under-representation of female athletes in their cited literature, relying on samples that were overall 80.1% male (NATA: 79.9%, ICCS: 87.8 %, AMSSM: 79.4%). Moreover, 40.4% of these studies include no female participants at all.
    CONCLUSION: Female athletes are significantly under-represented in the studies guiding clinical care for sport-related concussion for a broad array of sports and exercise medicine clinicians. We recommend intentional recruitment and funding of gender diverse participants in concussion studies, suggest authorship teams reflect diverse perspectives, and encourage consensus statements note when cited data under-represent non-male athletes.

      The paper aims to investigate the research patterns of Hungarian university full professors and career pathways in various disciplines. Hungary has a so-called 'multi-stage' formalized hierarchy that clearly defines the steps leading to achieve the appointment of full professor. Following the theoretical chapter in which different career scenarios - such as 'Top Researcher', 'Outstanding Lecturer' and 'Local Manager' are presented, an empirical analysis is carried out. The sample consists of a group of 327 professors. Our results point out that there are different research patterns and a significant gap can be observed between disciplines rather preferring international publication (scored by SJR) and the ones opting for publishing monographs. As far as career paths concerned, it was found that the number of years until reaching the PhD degree ranges between 6-13 years, 15.5-22 years are needed on average to achieve habilitation, while the time needed for getting the title of full professor ranges between 22-27 years. It is clearly perceivable that the gap in the number of years converges until reaching full professorship in each and every discipline.

       BACKGROUND: Statistically significant positive results are more likely to be published than negative or insignificant outcomes. This phenomenon, also termed publication bias, can skew the interpretation of meta-analyses. The widespread presence of publication bias in the biomedical literature has led to the development of various statistical approaches, such as the visual inspection of funnel plots, Begg test, and Egger test, to assess and account for it.
    OBJECTIVE: To determine how well publication bias is assessed for in meta-analyses of the neurosurgical literature.
    METHODS: A systematic search for meta-analyses from the top neurosurgery journals was conducted. Data relevant to the presence, assessment, and adjustments for publication bias were extracted.
    RESULTS: The search yielded 190 articles. Most of the articles (n = 108, 56.8%) were assessed for publication bias, of which 40 (37.0%) found evidence for publication bias whereas 61 (56.5%) did not. In the former case, only 11 (27.5%) made corrections for the bias using the trim-and-fill method, whereas 29 (72.5%) made no correction. Thus, 111 meta-analyses (58.4%) either did not assess for publication bias or, if assessed to be present, did not adjust for it.
    CONCLUSION: Taken together, these results indicate that publication bias remains largely unaccounted for in neurosurgical meta-analyses.

      Two years after COVID-19 came into being, many technologies have been developed to bring highly promising bedside methods to help fight this epidemic disease. However, owing to viral mutation, how far the promise can be realized remains unclear. Patents might act as an additional source of information for informing research and policy and anticipating important future technology developments. A comprehensive study of 3741 COVID-19-related patents (3,543 patent families) worldwide was conducted using the Derwent Innovation database. Descriptive statistics and social network analysis were used in the patent landscape. The number of COVID-19 applications, especially those related to treatment and prevention, continued to rise, accompanied by increases in governmental and academic patent assignees. Although China dominated COVID-19 technologies, this position is worth discussing, especially in terms of the outstanding role of India and the US in the assignee collaboration network as well as the outstanding invention portfolio in Italy. Intellectual property barriers and racist treatment were reduced, as reflected by individual partnerships, transparent commercial licensing and diversified portfolios. Critical technological issues are personalized immunity, traditional Chinese medicine, epidemic prediction, artificial intelligence tools, and nucleic acid detection. Notable challenges include balancing commercial competition and humanitarian interests. The results provide a significant reference for decision-making by researchers, clinicians, policymakers, and investors with an interest in COVID-19 control.
