      AbstractThe aim of the "One Belt and One Road" (OBOR) project proposed by China is to encourage extension of global value chains, facilitate regional integration and increase efficient resource allocation. In recent times, scientific literature has examined the investment decisions of the OBOR investment and how it will affect the governmental policies, environmental initiatives, and bilateral flow of economic resources. Current study, based on Web of Science database, uses bibliometric methodology to map the research trends in OBOR publications. We contribute in the economic literature in the associated fields of OBOR publications in the following ways: (1) identify the most influential researchers, articles, and academic institutions, (2) mapping the interdisciplinary character of OBOR investments and its bibliometric similarity to adjacent fields, (3) visualize nature and trends of the research field, and (4) synthesizing future research areas. Although OBOR initiative has received considerable traction, but to this date, there is no bibliometric study on this topic. The findings of current study will help policymakers and academics to navigate the OBOR literature, provide a systematic basis for developing the field, and suggest promising future research avenues.

      Diabetes mellitus (DM) is one of the leading causes of mortality in South Africa, which is impelled by people's consumption of unhealthy diets and lifestyles, negligence about an individual's health status, and increased urbanization. DM can be linked to several human diseases and thus, making it an important public health issue in the South African health sector. Therefore, it is necessary to assess the level of research that has been conducted in the country on diabetes, in a quest for solutions against the deadly disease. Hence, the present study aimed to map diabetes-related research in South Africa from 2010 to 2019. Data on the subject was retrieved from the Web of Science Core Collection (WoSCC) and bibliometrix package in Rstudio statistical software was used to analyze the data while VOSviewer was explored for data visualization networks. Our analysis revealed that the annual growth rate of publication trends was 23.2%. The authors per document were 23.3 with a collaboration index of 23.4. From the 416 articles analyzed, Islam MS (n = 34) was the most prolific author and the top active institution was University of KwaZulu-Natal (n = 165) and the top journal was Diabetes Research and Clinical Practice (n = 20). Findings from this study reveal that the quantity of research on diabetes has significantly increased over the decade, and the outcomes of this scientific progress can guide future research and substantially provide the basic needs for improving management procedures for diabetes in the country.

      Purpose: There are currently no available aids for authors when selecting ophthalmology journals to submit their manuscripts. We aim to provide comprehensive data on the duration from submission to various stages of the publication process and assess factors influencing time to publication in ophthalmology journals.Methods: A list of ophthalmology journals was obtained from the 2019 Web of Science Journal Citation Report. Journal characteristics, such as five-year impact factor, number of authors per article, journal type, and number of multi-institutional articles, were collected. The dates of submission, acceptance, electronic and print publication for all articles published in an ophthalmology journal in 2019 were determined.Results: In total, 56 journals and 8835 research articles were included. Of these articles, 3591 (40.6%) were open access and 4837 (54.7%) were multi-institutional. In 2019, most publications came from the United States of America (n = 1973), China (n = 1069) and Germany (n = 602). Significant associations were found between various predictors and a reduced mean number of days from submission to electronic publication: increased journal five-year impact factor (p = .026), more authors (p = .028), publishing in a hybrid journal (both open-access and subscription articles) versus an open-access journal (p = .021), and a reduced proportion of multi-institutional articles in a journal (p = .030).Conclusions: There is a wide variation in the time to acceptance and publication in ophthalmology journals. Authors can expect a shorter time to publication when publishing in high-impact journals.

      This report identifies the top cited papers in the field of periodontal regeneration since inception of the concept. Using the H-classics approach, 132 papers published between 1970 and 2012 were identified, with 230.0 ± 175.6 (mean ± SD) citations and 10.4 ± 11.5 citations/year. There were 46 clinical reports, 28 animal studies, 23 in vitro studies, 30 reviews, 3 systematic reviews, and 2 combined animal and in vitro studies. Analysis of covariance showed that institution number (≥3, P = 0.011), journal impact factor at publication (>3.0, P = 0.001) and study type (in vitro/reviews vs. clinical trials/animal studies, P = 0.024) were significantly associated with citations/year. This study has characterized the most influential literature in the field of periodontal regeneration and serves as a quick reference resource.

      We sought to determine the correlation between Altmetric Attention Score and traditional bibliometrics in the gynecologic oncology literature. We identified the 10 most-cited gynecologic oncology articles from 5 major gynecology journals and 10 major "oncology" journals that publish on gynecologic oncology during 2014, 2016, and 2018. Article citation count and Altmetric Attention Score (AAS), as well as journal impact factor (IF) and date of Twitter account development were recorded. Pearson's correlation coefficient was used to describe the relationship between AAS, tweets, IF, and citation count. While the median citation counts significantly decreased for the top-cited gynecologic oncology articles from 2014 to 2018 (p < 0.001), the corresponding median AAS continuously increased during this period (p = 0.008). For articles published in 2014 and 2018, there was a strong positive relationship between the median citation count and the median AAS (2014: r = 0.92; 2018: r = 0.97), as well as between the IF (r = 0.78 and r = 0.89, respectively); these correlations were moderate to weak in 2016 (r = 0.5 and r = 0.41, respectively). There was a continuously increasing strong positive correlation from 2014 to 2018 between journal IF and median AAS (2014: r = 0.75; 2016: r = 0.82; 2018: r = 0.92). Gynecologic oncology articles published in higher impact journals are associated with increased social media visibility and attention. Our data support the idea that early online attention scores, like the AAS, might be useful for predicting future citation counts for oncology publications in general and gynecologic oncology specifically.

      BACKGROUND: Thyroid carcinoma comprises the fastest rising incidence of carcinomas over the past decade. Papillary thyroid carcinoma (PTC) is the most predominant type of thyroid carcinoma. This study aimed to assess the research trends in the field of PTC.METHODS: Publications from January 2010 to December 2019 were retrieved from the Web of Science Core Collection database using Thompson Reuters. Searching strategies were determined according to Medical Subject Heading terms. Different kinds of bibliometrics software, such as HistCite and VOSviewer, and online bibliometrics analysis platforms were utilized to evaluate and visualize the results.
    RESULTS: A total of 8102 publications across 93 countries were identified, with the annual number of publications showing an increasing trend. The United States, China, and South Korea showed their dominant position in PTC publication outputs, H-index, total citations, and international collaborations. Thyroid was the most productive journal. Akira Miyauchi published the most articles, and the most productive institution was Yonsei University. The hotspots keywords proliferation, invasion and metastasis, diagnoses and prognoses, therapeutic resistance, recurrence, and microcarcinomas appeared earlier and were sustained over the last 3 years.
    CONCLUSIONS: This bibliometric study provides a comprehensive analysis delineating the scientific productivity, collaboration, and research hotspots within the PTC field, which will be very helpful when focusing on the direction of research over the next few years.

      BACKGROUND: Previous studies have demonstrated a correlation between national economic indicators and academic productivity. However, such a relationship has not been studied in the field of internal medicine (IM).METHODS: The number of documents published, number of citable documents, number of citations, citations per document and the h index between 1996 and 2019 in the field of IM among the Organisation for Economic Co-operation and Development (OECD) countries were analysed. Data were derived from the The Scimago Journal and Country rank source. We analysed the correlation between these indicators to the gross domestic product (GDP) per capita, health spending as percent of GDP and gross domestic expenditure on research and development as percent of GDP (GERD). Economic data were collected from the OECD websites.
    RESULTS: A significant correlation was found between health expenditure and h index (r=0.75, p<0.001), number of citations (r=0.72, p<0.001), number of documents (r=0.62, p<0.001) and number of citable documents (r=0.61, p< 0.001); between GERD and number of citations (r=0.6, p <0.001), h index (r=0.6, p<0.001), number of documents published (r=0.53, p=0.001) and citable documents (r=0.51, p=0.001); between the GDP per capita and number of citations (r=0.46, p=0.005), citations per document (r=0.54, p=0.001) and h index (r=0.5, p=0.002).
    CONCLUSIONS: This study demonstrated a positive correlation between academic productivity in the field of IM and economic indicators of the OECD countries, mainly health expenditure, implying the advantage of domestic investment in health.

      Objectives: To assess the productivity and visibility in research, clinical studies, treatment, use and production of antivenoms against poisonous snakes, scorpions and spiders.Methods: Bibliometric analysis of research and other activities. Articles on venoms and antivenoms published between 2000 and 2020 were retrieved from the Scopus database. The records were analyzed by bibliometric indicators including number of documents per year, journals, authors, and citation frequency. VOSviewer® v.1.6.13 was used to construct bibliometric networks for country co-authorships and co-occurrence of terms.
    Results: Australia, Brazil, Costa Rica and India were among the six top countries with most documents and were selected for more detailed analysis. Costa Rica was the country with the largest percentage of its publications dedicated to antivenom production and venomics. Only a few papers dealt with the issues of quality, safety, and efficacy of antivenoms or the role of the national regulatory authorities. The use of VOSviewer ® allowed visualization through joint publications of networking between countries. Visualization by co-occurrence of terms showed differences in the research carried out.
    Conclusions: Working in a collaborative and coordinated manner these four countries could have a major impact on envenoming globally. Attention should be given not only to antivenom production but also to strengthening regulatory oversight of antivenom products.

      Cohort studies collect, generate and distribute data over long periods of time - often over the lifecourse of their participants. It is common for these studies to host a list of publications (which can number many thousands) on their website to demonstrate the impact of the study and facilitate the search of existing research to which the study data has contributed. The ability to search and explore these publication lists varies greatly between studies. We believe a lack of rich search and exploration functionality is a barrier to entry for new or prospective users of a study's data, since it may be difficult to find and evaluate previous work in a given area. These lists of publications are also typically manually curated, resulting in a lack of rich metadata to analyse, making bibliometric analysis difficult. We present here a software pipeline that aggregates metadata from a variety of third-party providers to power a web based search and exploration tool for lists of publications. Alongside core publication metadata (i.e. author lists, keywords etc.), we include geocoding of first authors and citations in our pipeline. This allows a characterisation of a study as a whole based on common locations of authors, frequency of keywords, citation profile etc. This enriched publications metadata can be useful for generating project impact metrics and web-based graphics useful for public dissemination. In addition, the pipeline produces a research data set for bibliometric analysis or social studies of science.

      BACKGROUND: Procalcitonin (PCT) can effectively identify bacterial infections and can be used for risk prediction and antimicrobial treatment in patients with unexplained fever and critically ill patients. In this study, statistical analyses of the literature were performed to clarify the application and research status of PCT in respiratory diseases. Future research directions are discussed.METHODS: A literature search was conducted using the Science Citation Index Expanded (SCI-EXPANDED) database in the Web of Science Core Collection (WOSCC). Published literature between 1995 and February 6, 2021 were searched using the following strategies: subject term = procalcitonin; and Web of Science categories = Respiratory System. Using the Citespace software, the literature on the application of PCT in patients with respiratory diseases was analyzed in terms of annual publication status, subject distribution, country/institution distribution, journal distribution, author distribution, and keywords.
    RESULTS: A total of 542 related research literatures were identified, with the number of published papers and the number of literature citations increasing yearly. Research was mainly concentrated in the United States, China, Switzerland, and other countries, with countries such as the United Kingdom, the United States, and Canada being involved in international collaborations. Research institutions were mainly universities or hospitals such as the University Hospital of Basel, University of Barcelona, and Northwestern University. In particular, the University Hospital of Basel had extensive inter-hospital collaborations. Stolz et al. published many related papers, but the centrality value was low. Authors including Christ-Crain M, Schuetz P, and Stolz D were highly cited. Journals such as the American Journal of Respiratory and Critical Care Medicine, Chest, and the European Respiratory Journal were more influential. Keyword analysis showed that sepsis and pneumonia are the current hot topics.
    CONCLUSIONS: Related papers mainly focused on respiratory infections, especially sepsis and pneumonia. There were also a small number of studies suggesting that PCT is related to tumors.

      "Intensified TB research and innovation" is one of the three pillars of the End TB Strategy. To assess achievements and gaps in tuberculosis (TB) research productivity in countries and areas of the Western Pacific Region quantitatively, a bibliometric analysis was carried out by examining trends in the numbers of publications on TB indexed in PubMed between 2000 and 2019 and by comparing them with trends in publications on other selected major infectious diseases for the same period. The number of publications on TB in the Region increased by 3.2 times during the period, from 534 in 2000-2004 to 1714 in 2015-2019, as compared with 2.9 times each for HIV, hepatitis and malaria. The number increased by 46% in 2005-2009, 79% in 2010-2014 and 23% in 2015-2019, as compared with each previous 5-year period. The average annual growth rate between 2000 and 2018 was 8.8%. China accounted for 34.8% of the total number of publications on TB in the Region. Increases in TB research were observed in most countries and areas in the Region, particularly in those with a high TB burden. The number of publications on TB remained low, however, in the Lao People's Democratic Republic, Mongolia and Pacific island countries. Countries are encouraged to implement the set of actions proposed in the Global Strategy for TB Research and Innovation to accelerate progress towards ending TB.

      BACKGROUND AND AIMS: Women are numerically under-represented in the field of gastroenterology and hepatology. This study aims to characterize the gender distribution of first and senior authors and editorial board members across high impact factor journals in gastroenterology and hepatology.METHODS: Publications from January 1, 2019 to December 31, 2019 were reviewed from 29 journals. Gender of editorial board leadership, members, first, and senior authors were identified using publicly available data. Spearman correlation coefficients were calculated to assess for a relationship among editorial board, first author, and senior author gender and impact factor.
    RESULTS: Of 29 journals, (median impact factor 5.55) with 357 journal issues and 8036 articles, there were 3 out of 39 female chief editors (7.7%), 601 out of 3455 female editorial board members (17.4%), 2547 out of 8036 female first authors (31.7%), and 1390 out of 7335 senior authors (19%). No statistically significant correlations existed between impact factor or chief editor gender with gender distribution of editorial boards, first, or senior authors. Positive correlations existed between male-dominated editorial boards and male first (+0.52, p=0.005) and senior authorship (+0.56, p=0.002), whereas negative correlations occurred between male-dominated editorial boards and female first (-0.51, p=0.006) and senior authorship (-0.56, p=0.002). Positive correlations also existed between publication of first and senior authors of the same gender (+0.57, male p=0.001; +0.58, female p=0.001).
    CONCLUSION: Although gender distribution of female first authorship approaches current distributions in the field of gastroenterology and hepatology, editor-in-chief positions, editorial board membership, and senior authorship continue to be primarily male. Future endeavors to improve proportionate gender representation include improved journal leadership selection transparency, targeted diversity statements, and enhanced mentorship.

      Foot and ankle surgeons practicing within academic medicine balance clinical or surgical training, course instruction, administrative duties, and research. Along with clinical skills and patient volume, promotion within academia often relies on scholarly productivity. Previous research across specialties described this productivity using variables including publications, citations, and the h-index, a scale that quantifies the productivity and citation impact of published works, among academic ranks. As no studies examine the scholarly impact of foot and ankle surgeons with academic appointments, this study aimed to analyze the productivity and gender differences present in this specialty. A systematic review of academic-affiliated foot and ankle surgery residencies and fellowships was performed; and faculty members were screened for sex, academic rank, publication history, citations, h-index, and years in practice. Among 234 programs reviewed, 44 programs allowed for the analysis of 106 practitioners with an academic rank eligible for analysis. Overall, 78.3% of practitioners were male with the most common rank being assistant professor. Men published more documents and maintained higher citations as well as longer years in practice, and this was significant (p < .05). A significant difference was exhibited among all academic ranks (p ≤ .001). Multivariate regression revealed the publication history and years in practice are strongly correlated with the h-index of providers (p ≤ .001). Foot and ankle surgeons practicing in an academic setting may use the results of this study to gauge their productivity and identify benchmarks that similar providers have met at varying academic ranks.

      OBJECTIVE: The current study aimed at investigating the contribution of researchers in the Arab region to the field of mental health and well-being of university students using bibliometric tools.METHOD: Relevant literature was obtained from the Scopus database for the period from 2001-2020. Examples of keywords used in the query included "college student", "university student", and undergraduate student" combined with keywords such as wellbeing, wellness, suicide, and anxiety. No language restriction was used. Only research articles were considered. The search query was validated. Bibliometric indicators and mappings such as active countries, institutions, authors, highly cited documents, and the most frequently encountered topics were identified and discussed to shed light on research gaps in the Arab region. Research gaps were also identified. The analysis was carried out on February 12, 2021.
    RESULTS: The search query returned 309 research articles published by authors from 17 different Arab countries. Less than one-third (n = 97, 31.4%) of the retrieved articles were carried out in collaboration with authors from 39 non-Arab countries, mainly from the United Kingdom and the United States. The overall contribution of researchers from the Arab region to global research in the field was 5.6%. In total, 1212 authors from 791 different institutions participated in publishing the retrieved research articles. At the country level, Saudi Arabia (n = 125, 40.5%) ranked first, followed by Jordan, Egypt, and Lebanon. At the institutional level, The University of Jordan (n = 25, 8.1%) ranked first, followed by King Saud University, and Kuwait University. The retrieved articles included 132 (42.7%) articles on stress/distress, 95 (30.7%) on anxiety, 61 (19.7%) on depression. Knowledge gaps on suicide, eating disorders, substance use, and happiness were identified. The retrieved articles appeared in 193 different journals and approximately two-thirds of the active journal were in general medicine, public health, and education.
    CONCLUSIONS: The contribution of researchers in the Arab region to the field showed a noticeable increase with time. However, important research gaps were identified. The contribution was confined to authors from a limited number of Arab countries. Funding and international research collaboration for the mental health and well-being of students need to be strengthened.

      Objective The National Institute of Health (NIH) supports the academic career of scientists across the United States (U.S.). It promotes and sponsors scientists in conducting wide-ranging clinical and basic science research. Depending on the duration, research type, and budget, there are various types of grants awarded by NIH. Despite considerable advancement in biomedical sciences, female researchers remain underrepresented in obtaining NIH funding. Through this study, we aim to highlight the gender trends in NIH funding and grants. By doing this, we aim to facilitate effective future policymaking to help achieve gender parity in NIH grants and awards. Methods The data were obtained from the NIH Research Portfolio Online Reporting Tool (RePORT). The extracted data by gender were tabulated showing percentages of females as Research Grant Investigators, Research Career Development Award Recipients and Kirschstein-National Research Service Award (NRSA) Trainees and Fellows, recipients of Research Grants, Research Project Grants (RPGs), and R01 equivalent grants including types 1 or 2, over two decades (1999-2019). Absolute percentage change was also calculated and included in the tables. Results The percentage of females as NIH Research Grant Investigators has increased at centers, research centers as well as for RPGs and Small Business Innovation Research and Small Business Technology Transfer (SBIR/STTR) programs. For Research Career Development Award Recipients and Kirschstein-NRSA Trainees and Fellows, the proportion of female pre-doctoral institutional trainees, post-doctoral fellows, post-doctoral institutional trainees, mentored research career awardees, and other research career awardees have steadily increased. However, there was a decrease in the percentage of female pre-doctoral fellow awardees. The percentage of females receiving all RPGs, R01-New (type 1) and R01-Renewal (type 2) grants has also decreased.  Conclusion Despite an overall increase in the percentage of female researchers successfully receiving NIH grants and awards, they continue to lag compared to their male counterparts. With the increasing number of female doctoral graduates, it is imperative to address this disparity in NIH funding.

      BACKGROUND: This study aimed to assess the use of medical record items in clinical research in one large academic medical center in Taiwan.METHODS: A descriptive survey design was adopted to collect the data. Articles published in 2018 by Taipei Veterans General Hospital (TVGH) staff as the first author were obtained. The types of specialties and types of research were analyzed. To understand the conditions for the use of medical records, the retrospective research using hospital's medical records were analyzed. Each article was read in entirety to realize the use and number of patients and the medical record items.
    RESULTS: Among the 362 articles first-authored by TVGH staff in 2018, 219 (60.4%) were classified as clinical studies, 60 (16.6%) as basic studies, 53 (14.6%) as database studies, and 30 (8.2%) as other categories. About 50% of the retrospective research using TVGH medical records had a case number less than 100 (67 cases, 49.6%) with an average number of 41 cases and 13 studies (9.6%) had a case number greater than 1000. Analysis of the number of medical record items used in 135 retrospective research studies based on TVGH medical records showed that 118 (87.4%) used basic patient information. In addition to basic information, notes written by professionals were used most frequently (73 cases, 54.0%), whereas medication information was used in 50 cases (37.0%); laboratory test data was used in 49 cases (36.2%) ; and body measurements was used in 27 cases (20%).
    CONCLUSION: More than one-third of publications utilized medical records, but the patient numbers and record items in use were relatively limited. In the era of digitalization and big data analytics, the potential of medical records in research deserves attention. Investment in establishing a more accessible database of medical records to access nonstructural, descriptive medical records could be considered.

      For many decades English language was dominant in international scientific communications, but during the last decade it threatens to become the only language for communicating medical science at international level. The aim of this article was to make an overview of publication practices in regard to language of publication of MEDLINE-referenced articles from European countries in year 2020. Scientific publications referenced in MEDLINE database during year 2020 were chosen for analysis. The inclusion criteria were publications affiliated with one of European countries, published in either English or national languages of those countries. The countries with less than 100.000 inhabitants were excluded from the study. Only 11 of 38 European countries had any number of medical publications in national language that were referenced in MEDLINE; the authors from twenty-seven European countries completely stopped publishing in national language at international journals. While economic strenght of a country was strongly correlated with number of international publications per 100.000 inhabitants, the correlation with international papers published in national languages was much less pronounced. Researchers from majority of European countries are publishing their studies predominantly or only in international medical journals printed in English language. Additional efforts should be made in the future to promote publishing in national languages.

      BACKGROUND: The outbreak of coronavirus disease (COVID-19) severely damaged and endangered people's lives at the end of 2019. Risk communication plays an important role in the response to it successfully, which has been appreciated by the World Health Organization. Therefore, a comprehensive analysis of risk communication research is necessary, which can understand current research hotspots and reveal new trends.METHODS: In this study, we collected 1134 international articles from the Web of Science database and 3983 Chinese articles from the China National Knowledge Infrastructure database. Bibliometric and mapping knowledge domain analysis methods were used for temporal distribution analysis, cooperation network analysis, co-word network analysis, and burst detection analysis.
    RESULTS: The first article in this field was published by western scholars earlier, while the first Chinese article in 2002. Research institutions mainly come from universities. The USA plays a key role in this field. Chinese scholars had a closer cooperation network, but there was less cooperation among domestic institutions. Risk perception, trust, risk management, and risk information had always been the research hotspots in this academic. Trust, sentiment research, and public risk events were essential directions for the future. There are 25 burst words for international articles, while 11 burst words for Chinese articles from 2000 to 2020.
    CONCLUSIONS: In summary, both domestic and international researchers are concerned about risk communication, risk perception, trust, and risk information. International research on risk communication is systematic and comprehensive relatively. However, Chinese scholars take severe acute respiratory syndrome as the research background and reviewing foreign knowledge as the research starting point. With the purpose of practical and applied research based on a public emergency, the risk communication research lacks continuity in Chinese academy in the past years.

      Objective: We aimed to document the use of transparent reporting of hypotheses and analyses in behavioral medicine journals in 2018 and 2008.Design: We examined a randomly selected portion of articles published in 2018 and 2008 by behavioral medicine journals with the highest impact factor, excluding manuscripts that were reviews or purely descriptive.
    Main Outcome Measures: We coded whether articles explicitly stated if the hypotheses/outcomes/analyses were primary or secondary; if study was registered/pre-registered; if "exploratory" or a related term was used to describe analyses/aims; and if power analyses were reported.
    Results: We coded 162 manuscripts published in 2018 (87% observational and 12% experimental). Sixteen percent were explicit in describing hypotheses/outcomes/analyses as primary or secondary, 51% appeared to report secondary hypotheses/outcomes/analyses but did not use term "secondary," and 33% were unclear. Registration occurred in 14% of studies, but 91% did not report which analyses were registered. "Exploratory" or related term was used in 31% of studies. Power analyses were reported in 8% of studies. Compared to 2008 (n=120), studies published in 2018 were more likely to be registered and less likely to have explicitly stated if outcomes were primary or secondary.
    Conclusions: Behavioral medicine stakeholders should consider strategies to increase clarity of reporting, and particularly details that will inform readers if analyses were pre-planned or post-hoc.

      With the unparallel advance of leading-edge technologies like artificial intelligence (AI), the healthcare systems are transforming and shifting for more digital health. In recent years, scientific productions have reached unprecedented levels. However, a holistic view of how AI is being used for digital health remains scarce. Besides, there is a considerable lack of studies on responsible AI and ethical issues that identify and suggest practitioners' essential insights towards the digital health domain. Therefore, we aim to rely on a bibliometric approach to explore the dynamics of the interplay between AI and digital health approaches, considering the responsible AI and ethical aspects of scientific production over the years. We found four distinct periods in the publication dynamics and the most popular approaches of AI in the healthcare field. Also, we highlighted the main trends and insightful directions for scholars and practitioners. In terms of contributions, this work provides a framework integrating AI technologies approaches and applications while discussing several barriers and benefits of AI-based health. In addition, five insightful propositions emerged as a result of the main findings. Thus, this study's originality is regarding the new framework and the propositions considering responsible AI and ethical issues on digital health.

      Studies of research policies and scientific production are essential for strengthening educational systems and achieving objectives such as quality improvement. The aim of this study was to evaluate the influence of research policies on the scientific production of public and private Peruvian universities. An observational, descriptive, secondary analysis study of the research policies of 92 universities and two graduate schools licensed by the National Superintendence of Higher Education of Peru (SUNEDU) was conducted for the period from 2016-2020. Scientific publications from educational institutions were collected from Scopus and Web of Science for the study period, and researchers certified by the National Council of Science and Technology of Peru (CONCYTEC) were divided by group and level. Multiple regression analysis was performed using two models. The analysis indicated that research policies did not influence scientific production in Scopus or Web of Science in either 2019 or 2020 (Model I) but that type of management (p < 0.01), number of National Scientific, Technological, and Technological Innovation Registry (RENACYT) researchers (p < 0.001) and 2016 scientific production (p < 0.001) did influence production when these variables were incorporated into the model (Model II). However, time of licensing and management type had no effects. The number of research policies implemented by Peruvian universities and licensed graduate schools was not large. Therefore, it is recommended that project funding policies, research training, and research collaboration be strengthened and that the management capacity of research centers and institutes be increased.

      BACKGROUND: In recent years, the field of medical education has sought to amplify the voices of those from traditionally marginalised groups and medical education journals have sought to become more accessible and diverse. This study sought to examine the gender and geographical representation of editors and editorial board members in medical education journals.METHODS: Information about individual editors and editorial board members of 10 medical education journals was retrieved from their websites in January 2021, including their gender and the country in which they were based. Countries were categorised according to World Bank Income Classification and World Bank Geographical Regions. We then calculated the Composite Editorial Board Diversity Score for each journal.
    FINDINGS: Of 488 editors and editorial board members, 283 (58.0%) were male, 452 (92.6%) were based in high-income countries and 322 (66.0%) were from the four countries with greatest representation (the United States, the United Kingdom, Australia and Canada).
    DISCUSSION: The composition of medical education journals' editorial leadership teams remains dominated by males and those from higher income and Western countries. Strikingly, little change has taken place since this was last examined 17 years ago despite the field becoming apparently more globalised. As medical education strives to become a more inclusive and diverse discipline, developing policies to create more globally representative editorial leadership teams should now be an urgent priority.
