      OBJECTIVES: A bibliometric approach using network analysis was applied to identify the development and research trends for moxibustion. This study also examined the network hub of moxibustion research by investigating the collaborative work of organizations and authors.METHODS: Academic articles on moxibustion research published from 2000 to 2019 were retrieved from the Web of Science database. Extracted records were analyzed according to publication year, research area, journal title, country, organization, and authors. The VOSviewer program was utilized to visualize the trends in moxibustion research and to explore the influential organizations and authors.
    RESULTS: Analyses of 1146 original and review articles written in English demonstrated that the number of publications related to moxibustion research has increased consistently over the last 20 years. China issued the most articles in this field, and the most represented research area was integrative complementary medicine. A network analysis based on the co-occurrence and publication year of keywords identified the relevant characteristics and trends of moxibustion research. By assessing the total link strength of organizations and authors, influential organizations and authors who have contributed to moxibustion research were identified.
    CONCLUSIONS: The current study examined research on moxibustion using bibliometric analysis and identified a time-based development of moxibustion research and a global network hub of moxibustion research.

      STUDY DESIGN: Literature Review OBJECTIVE.: To discern which social media outlets contribute most to spine surgery literature dissemination and to investigate how popular articles compare to articles with most citations.SUMMARY OF BACKGROUND DATA: Scientific literature is increasingly disseminated through social media. The Altmetric Attention Score (AAS) is defined as an automated, weighted score calculation from counts of all online attention received by various research outputs. Increasing AAS values indicate more online attention. For example, the overall top 100 Altmetric spine surgery peer-reviewed articles since 2010 had an AAS range from 78 to 1,537. Among all spine surgery literature reviewed since 2010, the mean AAS was 5.3 with a median of 1.0.
    METHODS: We performed an Altmetric database search of nine spine surgery journals from January 2010-October 2019. Mean AAS was summarized alongside metrics including citation count and impact factor. We assessed correlations between AAS and online sources, readers, and citations. Journals were grouped by impact factor, and analysis-of-variance compared mean AAS. The 100 highest AAS articles were compared to the most cited.
    RESULTS: 13,601 articles were included. The mean AAS was 5.3, with Twitter contributing the most. The three highest associations were news (p < 0.001), Twitter (p < 0.001), and Facebook (p < 0.001). There was no significant association between impact factor and AAS. Compared to the most cited articles, the top 100 AAS articles had significantly more article types, more prospective studies, fewer retrospective studies, fewer reviews and fewer systematic reviews (p < 0.001 for all). Spine contributed the most articles in both top 100 sets.
    CONCLUSION: Our evaluation revealed Twitter, newsfeeds, and Facebook were the most significant social media outlets. Compared to articles with the most citations, the most popular articles are prospective and encompass broader study designs. Social media plays an integral role in dissemination, both within spine literature and the public sphere.

      Background and Objectives: The evaluative strength of available bibliometric tools in the field of clinical embryology has never been examined in the literature. The aim is to bring insight regarding the identity of clinical embryology research, introducing concerns when solely relying on the methodology of bibliometric analysis. Methods: An all-inclusive analysis of the most bibliometrically highlighted scientific contributions regarding the cornerstones of clinical embryology was performed employing the Scopus, Web of Science (WoS) and PubMed databases, between 1978-2018. An analysis of the number of publications, respective citations and h-index, g-index, along with m-quotient is presented. The top 30 contributing authors for each distinctive area of research are listed. An attempt at visualizing the yearly published articles, clusters, and collaborations of authors, along with the geographic origin of publications, is also presented. Results: Combining all searches and keywords yielded 54,522 results. In the Scopus database, employing the keyword "In Vitro Fertilization" yielded 41,292 results. The publications of the top five authors in each research field were analytically presented and compared to the total number of publications for each respective field. The research field of Preimplantation Genetic Diagnosis/Screening/Testing was allocated the highest percentage of publications produced by the top five authors. Regarding journal bibliometrics, based on the year 2017 metrics, there are only 29 journals according to WoS that refer to "Reproductive Biology", ranking it 187th among 235 disciplines. The USA produced the highest number of publications (12,537). Conclusion: Results indicate an explosion of interest published in the literature regarding the field of clinical embryology. Further analysis on collaborations and the trends involved should be of added value as productivity between countries varies significantly. This may guide researchers, in vitro fertilization professionals, and prospective authors during literature search, while proving useful regarding manuscript design and concurring on keywords and abstract content.

      PURPOSE: This study was undertaken to learn how predatory journal articles were cited in articles published in legitimate (nonpredatory) nursing journals. The extent of citation and citation patterns were studied.DESIGN: A two-phase approach was used.
    METHODS: In Phase 1, 204 articles published in legitimate nursing journals that cited a predatory publication were randomly selected for analysis from a list of 814 articles with predatory journal citations. In Phase 2, the four predatory journal articles that were cited most frequently were analyzed further to examine their citation patterns.
    FINDINGS: The majority (n = 148, 72.55%) of the articles that cited a predatory publication were research reports. Most commonly, the predatory article was only cited once (n = 117, 61.58%). Most (n = 158, 82.72%) of the predatory articles, though, were used substantively, that is, to provide a basis for the study or methods, describe the results, or explain the findings. The four articles in Phase 2 generated 38 citations in legitimate journals, published from 2011 to 2019, demonstrating persistence in citation. An evaluation of the quality of these articles was mixed.
    CONCLUSIONS: The results of this study provide an understanding of the use and patterns of citations to predatory articles in legitimate nursing journals. Authors who choose predatory journals as the channel to disseminate their publications devalue the work that publishers, editors, and peer reviewers play in scholarly dissemination. Likewise, those who cite these works are also contributing to the problem of predatory publishing in nursing.
    CLINICAL RELEVANCE: Nurse authors should not publish their work in predatory journals and should avoid citing articles from these journals, which disseminates the content through the scholarly nursing literature.

      BACKGROUND: The purpose of this study was to identify the top 100 cited articles dedicated to sleep medicine published in journals that have made key contributions to the field.METHODS: We performed a search of journals and selected 100 top-cited articles by utilizing the Institute for Scientific Information database available under the banner of the Web of Science. Next, we manually reviewed the contents of the top 100 cited articles. We examined the characteristics of the articles, such as the number of citations, ranking, authorship, article title, year of publication, publishing journal, publication type, and topic categories.
    RESULTS: The top-cited articles were published in 49 journals, and the most frequently cited journal was Sleep (23 articles). The top 100 cited articles originated from institutions in 9 countries, with the USA contributing 67 articles. The institution associated with the largest numbers of sleep medicine citation classics was Stanford University (11 articles). Morin CM, who was the first author for 6 articles, was listed most frequently in the sleep medicine citation classics. The publication years were concentrated in the 2000s, when 42 articles were published. The topics included 35 insomnia studies, 25 sleep physiology studies, 22 obstructive sleep apnea studies, and 19 other studies.
    CONCLUSIONS: The present study provides a detailed list of the most-cited articles on sleep medicine. This currently relevant approach provides an opportunity to recognize the classic articles on sleep, to provide useful insights into international leaders, and to describe research trends in the field of sleep medicine.

      BACKGROUND: Scientific activity for 3D bioprinting has increased over the past years focusing mainly on fully functional biological constructs to overcome issues related to organ transplants. This research performs a scientometric analysis on bioprinting based on a competitive technology intelligence (CTI) cycle, which assesses scientific documents to establish the publication rate of science and technology in terms of institutions, patents or journals. Although analyses of publications can be observed in the literature, the identification of the most influential authors and affiliations has not been addressed. This study involves the analysis of authors and affiliations, and their interactions in a global framework. We use network collaboration maps and Betweenness Centrality (BC) to identify of the most prominent actors in bioprinting, enhancing the CTI analysis.RESULTS: 2088 documents were retrieved from Scopus database from 2007 to 2017, disclosing an exponential growth with an average publication increase of 17.5% per year. A threshold of five articles with ten or more cites was established for authors, while the same number of articles but cited five or more times was set for affiliations. The author with more publications was Atala A. (36 papers and a BC = 370.9), followed by Khademhosseini A. (30 documents and a BC = 2104.7), and Mironov (30 documents and BC = 2754.9). In addition, a small correlation was observed between the number of collaborations and the number of publications. Furthermore, 1760 institutions with a median of 10 publications were found, but only 20 within the established threshold. 30% of the 20 institutions had an external collaboration, and institutions located in and close to the life science cluster in Massachusetts showed a strong cooperation. The institution with more publications was the Harvard Medical School, 61 publications, followed by the Brigham and Women's hospital, 46 papers, and the Massachusetts Institute of Technology with 37 documents.
    CONCLUSIONS: Network map analysis and BC allowed the identification of the most influential authors working on bioprinting and the collaboration between institutions was found limited. This analysis of authors and affiliations and their collaborations offer valuable information for the identification of potential associations for bioprinting researches and stakeholders.

      The coronavirus disease 2019 (COVID-19) pandemic aroused global public concern and became a major medical issue. This study aims to investigate the global research routine and trends of coronavirus over the last twenty years based on the production, hotspots, and frontiers of published articles as well as to provide the global health system with a bibliometric reference. The Web of Science core collection database was retrieved for coronavirus articles published from 1 January 2000 to 17 March 2020. Duplicates and discrete papers were excluded. Analysis parameters including time, regions, impact factors, and citation times were processed through professional software. A total of 9043 coronavirus articles originated from 123 countries and were published in 1202 journals. The USA contributed most articles (3101) followed by China (2230). The research was published in specialized journals including the Journal of Virology. Universities were the main institutions of science progress. High-impact articles covered fields of basic science and clinical medicine. There were two sharp increases in research yields after the severe acute respiratory syndrome (SARS) and the Middle East respiratory syndrome (MERS) outbreaks. International collaborations promoted study progress, and universities and academies act as the main force in coronavirus research. More research on prevention and treatment is needed according to an analysis of term density.

      In the field of nano- and microscale science and technology, Small has become one of the worldwide leading journals since its initiation 15 years ago. Among all the topics covered in Small, "nanosafety" has received growing interest over the years, which accounts for a large proportion of the total publications of Small. Herein, inspired by its coming Special Issue "Rethinking Nanosafety," a general bibliometric overview of the nanosafety studies that have been published in Small is presented. Using the data derived from the Web of Science Core Collection, the annual publication growth, most influential countries/institutions as well as the visualized collaborations between different countries and institutions based on CiteSpace software are presented. A special emphasis on the impact of the previous Special Issue from Small that is related to nanosafety research is given and the research trend from the most highly cited papers during last 15 years is analyzed. Lastly, future research directions are also proposed.

      Background: This study aims to quantitatively and qualitatively investigate the trends in scoliosis research and evaluate research hotspots using bibliometric analysis.Methods: All relevant publications on scoliosis from the period from 2009 to 2018 were extracted from the Web of Science and PubMed databases. Publication trends were analyzed using an Online analysis platform of literature metrology, Bibliographic Item Co-occurrence Matrix Builder (BICOMB), and CiteSpace software. Hotspots were analyzed and visualized using the gCLUTO software package.
    Results: A total of 7,445 scoliosis research publications dated between 2009 and 2018 were found. The spine was the most popular journal in this field during this period. The United States maintained a top position in global scoliosis research throughout the 10 years and has had a pivotal influence, followed by China and Canada. Among all institutions, the University of California, San Francisco, was a leader in research collaboration. At the same time, Professors Yong Qiu and Lawrence G. Lenke made great achievements in scoliosis research. We analyzed the major Medical Subject Headings (MeSH) terms/MeSH subheadings and identified eight hotspots in scoliosis research.
    Conclusions: We summarized the publication information of scoliosis-related literature in the 10 years from 2009 to 2018, including country and institution of origin, authors, and publication journal. We analyzed former research hotspots in the field of scoliosis and predicted future areas of interest. The development of various new orthopedic plants, artificial intelligence diagnosis, and genetic research will be future hotspots in scoliosis research.

      OBJECTIVE: To review the dynamics of neuroscience research in the Kingdom of Saudi Arabia (KSA) from 2013-2018.METHODS: Subject category of Neuroscience was selected in the SciVal feature of Scopus database, which includes all relevant categories of the field limiting it to Saudi Arabia.
    RESULTS: Saudi Arabia is ranked 39th in publishing neuroscientific research worldwide. The number of yearly published articles has increased from 123 to 332 during the time period between 2013 and 2018. King Saud University & King Abdul Aziz University & their corresponding regions namely Western and Central regions are the major contributors to publications. Neuroscientists working in Saudi Arabia have collaboration with scientists from all over the world. The top 10 preferred journals are all international. In subcategories of neuroscience, developmental neuroscience seems the one that needs attention.
    CONCLUSION: Neuroscience research is on the rise in KSA. Older and well-established institutions like King Saud University & King Abdul Aziz University have taken lead in publishing neuroscientific research. International collaboration in all subfields of neuroscience is substantial. Eastern Southern and Northern regions and developmental neuroscience require more focus and funding.

      INTRODUCTION: Prostate cancer is one of the most common cancer among men in the world. Radical prostatectomy is the gold standard treatment for localized prostate cancer but advanced diseases are treated with hormonal therapy. Unfortunately, this treatment is not curative and approximately after 2 years, castration resistant prostate cancer occurs. In this study we aimed to investigate the terminology of castration resistant and refractory, hormone resistant and refractory articles on Web of Science database.MATERIALS AND METHODS: We searched the articles in the title section such as castration resistant prostate cancer, castration refractory prostate cancer, hormone resistant prostate cancer and hormone refractory prostate cancer between 1975 and 2018. Categories, publication years, document types, authors, countries, funding agencies and citation reports were recorded in 4 groups.
    RESULTS: There were 6733 articles in the system. Most of the articles (72.16%) were published as using castration resistant title. The United States of America and Italy were in the top 5 countries in 4 titles. Oncology and urology nephrology categories consisted more than 80% of the articles. Of these articles, only 1745 (26%) articles had funding agency.
    DISCUSSION: Different terminology can be used in some diseases. One of these diseases is castration resistant prostate cancer which is referred to different terms such as castration refractory, hormone resistant and refractory. In this study we searched the literature and discussed the results.
    CONCLUSION: Castration resistant prostate cancer is a serious health problem for clinicians and patients. If international associations, journals and authors use the same terminology, the articles can be published without different titles in the literature.

      PURPOSE: To determine the characteristics of and trends in research in the emerging field of radiomics through bibliometric and hotspot analyses of relevant original articles published between 2013 and 2018.METHODS: We evaluated 553 original articles concerning radiomics, published in a total of 61 peer-reviewed journals between 2013 and 2018. The following information was retrieved for each article: radiological subspecialty, imaging technique(s), machine learning technique(s), sample size, study setting and design, statistical result(s), study purpose, software used for feature calculation, funding declarations, author number, first author's affiliation, study origin, and journal name. Qualitative and quantitative analyses were performed for the manually extracted data for identification and visualization of the trends in radiomics research.
    RESULTS: The annual growth rate in the number of published papers was 177.82% (p < 0.001). The characteristics and trends of research hotspots in the field of radiomics were clarified and visualized in this study. It was found that the field of radiomics is at a more mature stage for lung, breast, and prostate cancers than for other sites. Radiomics studies primarily focused on radiological characterization (215) and monitoring (182). Logistic regression and LASSO were the two most commonly used techniques for feature selection. Non-clinical researchers without a medical background dominated radiomics studies (70.52%), the vast majority of which only highlighted positive results (97.80%) while downplaying negative findings.
    CONCLUSIONS: The reporting of quantifiable knowledge about the characteristics and trajectories of radiomics can inform researchers about the gaps in the field of radiomics and guide its future direction.

      INTRODUCTION: The scientific outcome of Health Science PhD theses has been questioned by arguments suggesting that strategic motives are important for graduationamong clinical PhD graduates which may compromise scientific output and quality. This study aimed to investigate the scientific outcome of clinical PhD theses.METHODS: A total of 841PhD theses from the Department of Clinical Medicine, University of Copenhagen, were concluded in 2013-2017. These theses were examined, and all published manuscripts were identified in online databases. Thesis bibliographics, publication activity and article/journal impact of the published manuscripts were obtained between 21 March and 18 September 2019.
    RESULTS: Overall, 2,845 manuscripts were embedded in the theses (3.4 ± 0.8 manuscripts/thesis, mean ± standard deviation). A total of 56% and 92% of the manuscripts were published at the time of thesis submission and observation, respectively. The SCImago Journal Rank was 2.1 ± 1.7 and 82% of the manuscripts were published in journals with a field-specific ranking in the best quartile. The mean field-weighted citation impact of the published manuscripts was 102% higher than the world average.
    CONCLUSIONS: The scientific outcome of clinical PhD theses was high as 92% of all manuscripts were published with a field-weighted journal ranking and citation impact above the world average, indicating that the productivity and quality of the clinical PhD theses are not compromised even though strategic motives is a driver for graduation.
    FUNDING: This study was funded by theGraduate School of the Faculty of Health and Medical Sciences, University of Copenhagen.

      BACKGROUND: Traditionally health care professions education research (HCPER) is poorly funded, despite it being key to success.PURPOSE: This unique study maps HCPER evolution within a single country during a period when significant national governmental HCPER funding is introduced.
    METHODS: A scoping review method examined Taiwan's HCPER landscape across 12-years. Literature searches across four databases (OVID Medline; Scopus; Web of Science; the Airiti Library), a manual scan of HCPE journals and hand searches. Endnote and ATLAS.ti managed the data. Demographic and content codes were developed. PRISMA guidelines are used.
    DISCUSSION: One thousand four hundred and ten articles across 310 journals, with a steady rise in funded studies. Science/Social Science Citation Index and English language publications increased. Nursing Students/Nurses and Medical Students/Physicians are the most common populations. Significant associations with funding was found for indexed and English language publications. National funding influenced quality and local funding positively.
    CONCLUSION: Caution around local vs. global needs is highlighted and national funding policies for HCPER are advocated.

      Altmetric Explorer was searched for the most popular online articles published in Pubmed-indexed journals. The 75 articles with the highest Altmetric Attention Score (AAS) were screened for article information (date, journal, access), authorship (number of authors, affiliation and origin of the corresponding author), and research (type, subject, funding). The reviewed articles displayed a mean AAS of 241.52, were broadcast 17.03 times by news agencies, posted on Twitter 101.47 times, downloaded by 67.21 Mendeley readers, and received 62.67 citations. There was intense online interest in the transgender health literature, mainly related to mental health and social well-being. Online visibility of transgender health articles was not significantly correlated with citation counts, implying that the public, likely including transgender persons and allies, may place emphasis on different health issues than scholars. Monitoring altmetrics and interactions on electronic media may help researchers conduct research that is more meaningful to transgender individuals, and to society in general.

      Importance: Incomplete reporting of diagnostic accuracy research impairs assessment of risk of bias and limits generalizability. Point-of-care ultrasound has become an important diagnostic tool for acute care physicians, but studies assessing its use are of varying methodological quality.Objective: To assess adherence to the Standards for Reporting of Diagnostic Accuracy (STARD) 2015 guidelines in the literature on acute care point-of-care ultrasound.
    Evidence Review: MEDLINE was searched to identify diagnostic accuracy studies assessing point-of-care ultrasound published in critical care, emergency medicine, or anesthesia journals from 2016 to 2019. Studies were evaluated for adherence to the STARD 2015 guidelines, with the following variables analyzed: journal, country, STARD citation, STARD-adopting journal, impact factor, patient population, use of supplemental material, and body region. Data analysis was performed in November 2019.
    Findings: Seventy-four studies were included in this systematic review for assessment. Overall adherence to STARD was moderate, with 66% (mean [SD], 19.7 [2.9] of 30 items) of STARD items reported. Items pertaining to imaging specifications, patient population, and readers of the index test were frequently reported (>66% of studies). Items pertaining to blinding of readers to clinical data and to the index or reference standard, analysis of heterogeneity, indeterminate and missing data, and time intervals between index and reference test were either moderately (33%-66%) or infrequently (<33%) reported. Studies in STARD-adopting journals (mean [SD], 20.5 [2.9] items in adopting journals vs 18.6 [2.3] items in nonadopting journals; P = .002) and studies citing STARD (mean [SD], 21.3 [0.9] items in citing studies vs 19.5 [2.9] items in nonciting studies; P = .01) reported more items. Variation by country and journal of publication were identified. No differences in STARD adherence were identified by body region imaged (mean [SD], abdominal, 20.0 [2.5] items; head and neck, 17.8 [1.6] items; musculoskeletal, 19.2 [3.1] items; thoracic, 20.2 [2.8] items; and other or procedural, 19.8 [2.7] items; P = .29), study design (mean [SD], prospective, 19.7 [2.9] items; retrospective, 19.7 [1.8] items; P > .99), patient population (mean [SD], pediatric, 20.0 [3.1] items; adult, 20.2 [2.7] items; mixed, 17.9 [1.9] items; P = .09), use of supplementary materials (mean [SD], yes, 19.2 [3.0] items; no, 19.7 [2.8] items; P = .91), or journal impact factor (mean [SD], higher impact factor, 20.3 [3.1] items; lower impact factor, 19.1 [2.4] items; P = .08).
    Conclusions and Relevance: Overall, the literature on acute care point-of-care ultrasound showed moderate adherence to the STARD 2015 guidelines, with more complete reporting found in studies citing STARD and those published in STARD-adopting journals. This study has established a current baseline for reporting; however, future studies are required to understand barriers to complete reporting and to develop strategies to mitigate them.

      With the development and deepening of the process of global integration, global health is gaining increasing attention. An increasing number of studies have examined global health from diverse perspectives to promote the realization of global public health. The purpose of this research is to systematically and comprehensively evaluate the knowledge structure, knowledge domain, and evolution trend in the field of global health research. Based on the 14,692 document data retrieved from Web of Science Core Collection from 1996 to 2019, this article carried out a visual analysis of global health research from the perspective of scientific output characteristics, scientific research cooperation networks, keywords, and highly cited literature. The results show that scholars' interest in global health research is increasing, especially after the outbreak of SARS. USA, England, Canada, Australia, and China have the most prominent contributions to global health research. Significant authors, high impact journals and core institutions also identified. The study found that "global health governance", "global health diplomacy", "medical education", "global health education" and "antimicrobial resistance" are the research frontiers and hot spots. This study provides an overview and valuable guidance for researchers and related personnel to find the research direction and practice of global health.

      Since its introduction into the medical community, the Podiatric Medicine and Surgery residency has strived to graduate the most advanced and learned foot and ankle surgeons. From increasing length of training, to assuring didactics and education are sufficiently incorporated into the residency, the Council on Podiatric Medical Education has overseen this transition. One area of interest, podiatric medicine and research, remains central to this training and contributes to the field of foot and ankle surgery through journal publications. The purpose of this review was to identify Podiatric Medicine and Surgery resident-authored publication rates, trends, and geographic distribution. All published case reports, original research articles, review articles, and tips, quips, and pearls in The Journal of Foot and Ankle Surgery from January 2009 to December 2018 were reviewed. Podiatric Medicine and Surgery residents comprised 8% of all authors. Residents contributed to and published as first authors in 22% and 11% of all manuscripts, respectively. An increasing trend in resident authors, resident-authored manuscripts, and resident-first-authored manuscripts was observed. From before the mandated 3-year residency to after, the proportion of resident-authored manuscripts to all manuscripts declined from 9.99% to 7.21%; however, among these resident-authored publications, the rate of first-authorship increased from 45.32% to 51.36%. To the best of our knowledge, this is the first and only study to examine publication rates among foot and ankle surgery residents.

      BACKGROUND AND OBJECTIVES: The congress of the German Society of Urology reflects urologic research in German-speaking countries. The objective was to identify trends by analyzing the congress' abstracts and following full publications longitudinally.MATERIALS AND METHODS: The abstracts of the 2016 congress were systematically analyzed regarding content, study design, cooperation, following full publications and journals which they were published in. Thereafter, the 2016 congress was compared to the 2002 and 2009 congresses. Statistical analysis included χ2-, Mann-Whitney U-, Cochran-Armitage-, and Kruskal-Wallis test.
    RESULTS: A total of 1073 abstracts were presented at the 2002, 2009, and 2016 congresses. We found an increase in abstracts regarding prostate disease (24.2%, 29.7%, and 34.0%; p = 0.0043), oncological abstracts (50.6%, 57.9%, and 61.7%; p = 0.003), multicenter studies (18.3, 28.6, and 34.3%; p < 0.0001) and cooperation (55.6%, 62.9%, and 70.5%, p < 0.0001). Experimental (29.0%, 33.2%, and 22.8%; p = 0.009) and prospective studies (62.1%, 42.0%, and 36.0%; p < 0.0001) declined. Abstracts including statistical analysis (18.4%, 14.7%, and 41.2%; p < 0.0001) and the impact factor of following full publications (2.08, 3.42, 4.42; p < 0.0001) rose. In 2016, 11.2% of those full publications were published Open Access. The publication rates of the presented abstracts were 49.1%, 56.3%, and 52.3%, respectively (p = 0.15).
    CONCLUSIONS: National and international networking of the urological research community has increased. Presentation of prospective studies has declined. The rate of peer-reviewed full publications following the DGU abstracts remains at a stable high level over the three congresses. The publication rate in Open Access journals is low.

      OBJECTIVES: Despite the rising risk factor exposure and non-communicable disease (NCD) mortality across the Middle East and the North African (MENA) region, public health policy responses have been slow and appear discordant with the social, economic and political circumstances in each country. Good health policy and outcomes are intimately linked to a research-active culture, particularly in NCD. In this study we present the results of a comprehensive analysis of NCD research with particular a focus on cancer, diabetes and cardiovascular disease in 10 key countries that represent a spectrum across MENA between 1991 and 2018.METHODS: The study uses a well validated bibliometric approach to undertake a quantitative analysis of research output in the ten leading countries in biomedical research in the MENA region on the basis of articles and reviews in the Web of Science database. We used filters for each of the three NCDs and biomedical research to identify relevant papers in the WoS. The countries selected for the analyses were based on the volume of research outputs during the period of analysis and stability, included Egypt, Iran, Jordan, Kuwait, Lebanon, Oman, Qatar, Saudi Arabia, Turkey and the United Arab Emirates.
    RESULTS: A total of 495,108 biomedical papers were found in 12,341 journals for the ten MENA countries (here we consider Turkey in the context of MENA). For all three NCDs, Turkey's output is consistently the highest. Iran has had considerable growth in research output to occupy second place across all three NCDs. It appears that, relative to their wealth (measured by GDP), some MENA countries, particularly Oman, Qatar, Kuwait and the United Arab Emirates, are substantially under-investing in biomedical research. In terms of investment on particular NCDs, we note the relatively greater commitment on cancer research compared with diabetes or cardiovascular disease in most MENA countries, despite cardiovascular disease causing the greatest health-related burden. When considering the citation impact of research outputs, there have been marked rises in citation scores in Qatar, Lebanon, United Arab Emirates and Oman. However, Turkey, which has the largest biomedical research output in the Middle East has the lowest citation scores overall. The level of intra-regional collaboration in NCD research is highly variable. Saudi Arabia and Egypt are the dominant research collaborators across the MENA region. However, Turkey and Iran, which are amongst the leading research-active countries in the area, show little evidence of collaboration. With respect to international collaboration, the United States and United Kingdom are the dominant research partners across the region followed by Germany and France.
    CONCLUSION: The increase in research activity in NCDs across the MENA region countries during the time period of analysis may signal both an increasing focus on NCDs which reflects general global trends, and greater investment in research in some countries. However, there are several risks to the sustainability of these improvements that have been identified in particular countries within the region. For example, a lack of suitably trained researchers, low political commitment and poor financial support, and minimal international collaboration which is essential for wider global impact.
