      Citing an earlier study on eminence in psychology, Simonton (2016) argued that associations between measures of scholars' reputation, scientific productivity, and citation counts are only small to moderate [Simonton, D. K. (2016). Giving credit where credit's due: Why it's so hard to do in psychological science. Perspectives on Psychological Science, 11, 888-892]. However, this reading is based on partial regression coefficients, which underestimate the joint explanatory power of correlated variables. A reanalysis of the original data showed that a composite bibliometric index was substantially associated with reputation (β = 0.70; 46% explained variance). Very similar results were obtained with a newly calculated h index (β = 0.67; 42% explained variance). Although both Simonton's original analysis and the current reanalysis are inherently limited, the data suggest that the reputation of psychologists tracks their scientific contribution more closely than has been acknowledged in the recent literature.

      We examined the long-term impact of coauthorship with established, highly-cited scientists on the careers of junior researchers in four scientific disciplines. Here, using matched pair analysis, we find that junior researchers who coauthor work with top scientists enjoy a persistent competitive advantage throughout the rest of their careers, compared to peers with similar early career profiles but without top coauthors. Such early coauthorship predicts a higher probability of repeatedly coauthoring work with top-cited scientists, and, ultimately, a higher probability of becoming one. Junior researchers affiliated with less prestigious institutions show the most benefits from coauthorship with a top scientist. As a consequence, we argue that such institutions may hold vast amounts of untapped potential, which may be realised by improving access to top scientists.

      Literature databases (i.e., PubMed, Scopus, and Web of Science) differ in terms of their coverage, focus, and the tool they provide. PubMed focuses mainly on life sciences and biomedical disciplines, whereas Scopus and Web of Science are multidisciplinary. The protocol described in the current study was used to search for publications from Jordanian authors in the years 2013-2017. In this protocol, how to use each database to conduct this type of search is explained in detail. A Scopus search resulted in the highest number of documents (11,444 documents), followed by a Web of Science search (10,943 documents). PubMed resulted in a smaller number of documents due to its narrower scope and coverage (4,363 documents). The results also show a yearly trend in: (1) the number of publications, (2) the disciplines that have the most publications, (3) the countries of collaboration, and (4) the number of open access publications. In contrast, PubMed has a sophisticated keyword optimization service (i.e., Medical Subject Heading, or MeSH), while both Scopus and Web of Science provide search analysis tools that can produce representative figures. Finally, the features of each database are explained in detail and several indices that can be extracted using the search results are provided. This study provides a base for using literature databases for bibliometric analysis.

      Objective: As journal impact factors (IFs) can be artificially inflated by excessive journal self-citation practices, research quality evaluation based solely on IF ranking may be manipulated and, therefore, ethically challenged. This study aimed to analyze the longitudinal development of journal self-citation rates (SCRs) and IFs in dental literature and to determine possible confounders.Methods: Twenty-eight journals with scope within general dentistry and (sub)specialties listed in 1997-2016 Journal of Citation Reports® were scrutinized. The following information was retrieved: publication year, total number of citations, number of self-citations, IF, corrected IF, and SCR.Results: Endodontic journals had the highest SCR (median = 35.3, IQR = 21.6-47.5), journals related to periodontics had the lowest (median = 14.7, IQR = 8.9-25.5). Periodontics had the highest IF (median = 2.1, IQR= 1.7-2.8) and general dentistry had the lowest (median = 0.9, IQR = 0.7-1.2). SCR significantly decreased over time (p < .0001) by 1 unit per year. Additionally, 1 unit increase in corrected IF resulted in 15.2 units decrease in SCR. IFs significantly increased 0.06 units per year (p < .000).Conclusions: Overall, favourable changes in citation metrics have been observed for dental journals during the 20-year observation period. SCR significantly decreased per observation year whereas IFs significantly increased, indicating a healthy publishing environment in the dental literature. SCR was regulated both by time and corrected IF.

      Objective: To investigate the visual application of the CiteSpace software in the field of work-related musculoskeletal disorders (WMSDs) . Methods: The literature on WMSDs research, published from 1991 to 2017, was retrieved in Web of Science database. The CiteSpace 5.2 was used to make visualization analysis on the hotspots and tendency of the keywords, authors, countries (regions) and research institutes in relevant literature. Results: A total of 3224 literatures were included in the analysis. The amount of the literatures published was increasing annually. The key word co-occurrence network showed that the research hotspots mainly focused on the study of epidemiology, risk factors, symptoms, and other aspects of WMSDs. The cooperation network and time network of counties and regions showed that America and Europe were at the leading position in the field of WMSD, and the top three were America, Canada and Sweden. The developing countries, like Brazil and China, had also begun to make relative research since 2000. In research cooperation, the collaboration among countries, research institutions was relatively close, and multiple leading core authors and teams were formed in the international arena. Conclusion: The CiteSpace software can directly demonstrate the hotspots and tendency in the area of WMSDs.

      Social media use by professional organizations has increased as a platform to disseminate information, affording an alternative avenue to engage membership and the public. The American Journal of Neuroradiology (AJNR) posts cases and articles, hosts Tweet chats, advertises podcasts, and more on its Twitter account (@TheAJNR). The objective of this study was to determine whether user engagement is underestimated on the basis of publicly available metrics and to assess the engagement rate. This study demonstrated that engagement extends beyond visible metrics, suggesting an AJNR "silent" following beyond what is readily apparent. Median engagement rates from the @TheAJNR account from 2017 to 2019 appear stable since last reported in 2016 and are comparable with those reported in other professional medical journals.

      PURPOSE: Medical humanities is a field which implies collaborative work across disciplines although the degree to which this actually occurs is unknown. Our purpose was to determine the degree of joint work in medical humanities through analysis of authorship and acknowledgements in the two main medical humanities journals.METHODS: Observational survey of authorship. We studied authorship data in all papers published in the two major general medical humanities journals between 2009 and 2018 (n=595).
    RESULTS: Two-thirds of papers (67.4%) had single authors, of whom a majority declared a single disciplinary affiliation (70.3%). The titles of 60.8% of papers explicitly suggested collaborative content of which 19.9% had multiple authors from more than one discipline (not within the same school); of the remainder, almost half (48.1%) had a single, single-disciplinary author (although 8.5% demonstrated interdisciplinarity in the acknowledgements). One-third of papers (193/595;33%) referenced one or more people in the acknowledgements. Among papers whose titles suggested humanities or medical content only, authorship lists of 10.2% and 17.9% respectively demonstrated collaborative scholarship.
    CONCLUSIONS: Despite considerable involvement from both humanities and medical practitioners, there is still substantial scope for enhanced emphasis on collaborative (multi-, inter- and trans-disciplinary) seminars and exchanges in the medical humanities and editorial policies to promote transparency of the nature of collaborative work among disciplines. Journal editors and editorial boards should reflect on the opportunity to promote enhanced visibility of joint work in scholarship in the medical humanities through reflection and review of current editorial policies.

      Importance: The number of citations can be used to show the influence of an article or to measure the validity of a research study. The article by Wakefield et al that fraudulently reported an association between vaccination and autism continues to accumulate citations even after it was retracted.Objectives: To examine the characteristics of citations from scholarly literature that reference the 1998 article by Wakefield et al and to investigate whether authors are accurately citing retracted references.
    Design, Setting, and Participants: In this cross-sectional bibliographic analysis of the scholarly publications that cited a 1998 article by Wakefield et al, cited references were collected from a Web of Science Core Collection search performed on March 11, 2019. A total of 1211 articles were identified, with 58 citing works excluded because they were non-English-language publications or the citation to the study by Wakefield et al could not be located by reviewers. Citing works consisted of books, research articles, letters, editorials, news items, and other scholarly literature. Citations to the article by Wakefield et al were identified and analyzed by 2 reviewers in a blinded screening. Reviewers assigned a characteristic to each citation and indicated whether the retraction was documented.
    Main Outcomes and Measures: The characteristics of citations to the article by Wakefield et al, were categorized as negative, affirmative, or contrastive; if not, persuasive; and if not, assumptive, perfunctory, methodologic, or conceptual. Whether the partial retraction or notice of retraction was included in the citing work was also documented.
    Results: Among the 1153 citing works included in this analysis, the most common citation characteristics were negative (838 [72.7%]) followed by perfunctory (106 [9.2%]) and affirmative (94 [8.2%]). A total of 123 of 322 citing works (38.2%) published between 2005 and 2010 documented the partial retraction. After the notice of retraction was published in 2010, the percentage of citing works that documented the partial retraction and/or notice of retraction between 2011 and 2018 increased to 360 of 502 (71.7%).
    Conclusions and Relevance: Since the article by Wakefield et al was initially published, authors have mostly negated the findings of the study. A significant number of authors did not document retractions of the article by Wakefield et al. The findings suggest that improvements are needed from publishers, bibliographic databases, and citation management software to ensure that retracted articles are accurately documented.

      BACKGROUND: Publication of scientific work, although mandatory to ensure dissemination of novel research findings and obtain further funding, can require considerably more time and effort compared to conference presentations. Several national or scientific societies have determined the publication rate of studies reported at their meetings. The French Society for Orthopaedic and Trauma Surgery (Société française de chirurgie orthopédique et traumatologique, SoFCOT) has not yet measured this parameter. The objective of this study was to (i) evaluate the full-text publication rate of studies accepted in abstract form for podium presentations or posters at the 2013 SoFCOT meeting and (ii) identify characteristics of abstracts associated with subsequent full-text publication.HYPOTHESIS: The full-text publication rate of abstracts accepted for the 2013 SoFCOT meeting was equal to or greater than the mean reported by national societies, i.e., 44.5%.
    MATERIAL AND METHODS: Publication rates of the 503 studies reported as abstracts at the 2013 SoFCOT meeting were studied. The time horizon was thus at least 5years. The topic was orthopaedic surgery for 315 (62.6%) abstracts, trauma surgery for 153 (30.4%) abstracts, and fractures in elderly patients - the cross-field theme for that year - for 35 (7.0%) abstracts. Reporting was as a podium presentation for 275 (54.7%) abstracts, an e-poster for 205 (40.8%) abstracts, an instructional course lecture for 20 (4.0%) abstracts, a symposium for 2 (0.4%) abstracts, and a round table for 1 (0.2%) abstract.
    RESULTS: The full-text publication rate was 35.6% overall and 47.1% (139 publications) for podium presentations. Mean time from podium or poster presentation at the SoFCOT meeting to full-text publication was 1.2±1.5years (range: -2.5 to 6.1years). The full-text publications had 0.8±2.3 (range: -6 to 11) more authors compared to the abstract. They appeared in 54 journals with a mean impact factor of 1.9±1.3 (range: 0.25 to 13.77; median: 1.41; interquartile range: 1.26 to 2.47). Subgroup comparisons showed that full-text publication was more common for prospective than retrospective studies (50.0% versus 30.5%, p<0.0001) and for studies showing a significant difference (48.6% versus 33.0%, p<0.0001). Systematic reviews were more often published in full than were anecdotal case-reports. The full-text publication rate was also higher for studies reported as podium presentations than as e-posters (47.1% versus 17.6%, p<0.0001). Finally, studies of orthopaedic surgery were more often published in full than were studies of trauma surgery (39.7% versus 28.2%, p=0.033).
    DISCUSSION: The 5-year full-text publication rate of studies reported as abstracts at the 2013 SoFCOT meeting was consistent with previously reported data. The impact factors of the journals in which the studies were published are evidence of the high quality of the information shared at SoFCOT meetings.

      BACKGROUND: The rapid decrease in international funding for HIV/AIDS has been challenging for many nations to effectively mobilize and allocate their limited resources for HIV/AIDS programs. Economic evaluations can help inform decisions and strategic planning. This study aims to examine the trends and patterns in economic evaluation studies in the field of HIV/AIDS and determine their research landscapes.METHODS: Using the Web of Science databases, we synthesized the number of papers and citations on HIV/AIDS and economic evaluation from 1990 to 2017. Collaborations between authors and countries, networks of keywords and research topics were visualized using frequency of co-occurrence and Jaccards' similarity index. A Latent Dirichlet Allocation (LDA) analysis to categorize papers into different topics/themes.
    RESULTS: A total of 372 economic evaluation papers were selected, including 351 cost-effectiveness analyses (CEA), 11 cost-utility analyses (CUA), 12 cost-benefit analyses (CBA). The growth of publications, their citations and usages have increased remarkably over the years. Major research topics in economic evaluation studies consisted of antiretroviral therapy (ART) initiation and treatment; drug use prevention interventions and prevention of mother-to-child transmission interventions. Moreover, lack of contextualized evidence was found in specific settings with high burden HIV epidemics, as well as emerging most-at-risk populations such as trans-genders or migrants.
    CONCLUSION: This study highlights the knowledge and geographical discrepancies in HIV/AIDS economic evaluation literature. Future research directions are also informed for advancing economic evaluation in HIV/AIDS research.

      Publication numbers have been widely used as measure of research output, especially academic and university research. Publication numbers in tissue engineering (TE) have increased year by year since early 1990s. However, after an exponential growth phase, recently publications increase at lower rates, suggesting a consolidation process in which reviews become a relevant and high evidence document type. The aim of this study is to perform a scientometric evaluation of published literature reviews on TE in order to assess the status of scientific evolution and confirm the consolidation of TE as a research area. Published reviews on TE from 1991 to 2018 were retrieved from Web of Science core collection and this corpus of knowledge was analyzed by growth rate, research area, source title and citation. Our results revealed that TE can be considered a consolidating area as it leaves the forefront stage of a gompertzian growth curve model. Original research/review ratio is lineally decreasing during the last decade. The emergence of reviews serves to confirm and refute hypothesis and build up a more reliable theoretical framework as well as a guide for future educational approaches. Distribution assessment of categories and journals indicates the multidisciplinary profile of this area focused on the design and development of new tissues. Biomedical sciences become relevant productors of reviews to as they need to support TE innovations with high evidence leading to a safer and more efficient treatment of current injuries and diseases.

      OBJECTIVE: To evaluate the methodological quality and reporting quality of Meta-analysis literature published by acupuncture journals included in Chinese Science Citation Database (CSCD), and to provide references and demonstration for relevant studies.METHODS: The Meta-analysis literature published before December 2017 in Chinese Acupuncture & Moxibustion, Acupuncture Research, Journal of Acupuncture and Tuina Science and World Journal of Acupuncture-Moxibustion was retrieved by computer. AMSTAR was used for methodology quality evaluation, and PRISMA was used for reporting quality evaluation.
    RESULTS: A total of 69 literature was included. Among them, the co-authorship rate was 100% and the cooperation degree was 5.45. The first authors came from 32 institutions, and 29 literature (42.0%) was funded. The cited rate was 98.6%, and averagely each paper was cited 16.3 times. The mean score of methodology quality evaluation was (7.78±1.14) points, including 14 high-quality literature (20.3%), 50 moderate-quality literature (72.5%) and 5 low-quality literature (7.2%). The average score of reporting quality evaluation was (20.33±2.36) points, including 24 relatively complete literature (34.8%), 41 literature with certain defects (59.4%) and 4 literature with serious defects (5.8%).
    CONCLUSION: The Meta-analysis reports published by acupuncture journals in CSCD have relatively high methodological quality and reporting quality, which could provide evidence for clinical decision making, but still the quality level needed to be further enhanced according to the writing standard of Meta-analysis report. At the same time, the overall level of experimental research should be constantly improved to promote the development of evidence-based research on acupuncture and promote the formation of high-quality evidence.

      Background: Neurosciences research has increased significantly in recent years around the world. It has led to the development of interdisciplinary work, moving from activities from isolated fields (such as biology, psychology or neurology) to research that involves different scientific perspectives. In developing regions, such as Latin America, it has additional challenges, related to available funding and infrastructure.Aim: To analyze key factors in scientific productivity in neurosciences in Latin America.Methods: A bibliometric analysis of the scientific productivity in neurosciences in main five Latin American countries (Argentina, Brazil, Chile, Colombia and Mexico) was carried out.Results: Brazil was the largest producer of scientific articles, and receptor of citations, in neurosciences in 1998-2017, followed by Mexico. We identified highly cited papers, top institutions, networks of authors, main journals and key areas in neurosciences for this period in the 5 countries.Conclusions: Scientific productivity in neurosciences in Latin America would benefit from the consolidation of more regional, interdisciplinary and international research networks. In this work, we discuss key elements for the consolidation of neurosciences research in Latin America.

      BACKGROUND: Little is known about the scientific publication output for individual countries and medical specialties. The contribution of French authors to the currently expanding volume of publications on orthopaedics and traumatology (OT) is unclear. Orthopaedics & Traumatology: Surgery & Research (OTSR) is an English-language version of a preexisting French journal that was launched in 2009 to increase the dissemination of research done in France. The objective of this study was to use Web of Science (WoS) data from 1998 to 2017 to determine (i) the contribution of OT publications to the total worldwide volume of scientific publications, (ii) the contribution of OT publications from France to the total worldwide volume of OT publications, and (iii) changes over time in the proportion of OT publications from France with special attention to potential effects of the creation of OTSR.HYPOTHESIS: The proportion of OT publications from France increased after 2010-2012, indicating a positive effect of OTSR.
    MATERIAL AND METHODS: WoS data were used to identify original studies and review articles written by at least one French author, published between 1998 and 2017, and dealing with OT (defined as orthopaedics and/or traumatology in adult and/or paediatric patients). The worldwide volumes of publications in OT and other specialties were compared. Within worldwide OT publications, the proportion from France was determined. Indicators of impact were evaluated during successive 5-year periods. Finally, the position of OT in worldwide research was assessed and OT journals were analysed.
    RESULTS: Among worldwide scientific medical publications, the proportion dealing with OT increased year on year from 1.93% in 1998 to 2.65% in 2017. Among annual publications from France, the proportion dealing with OT rose similarly, from 1.32% to 2.40%. Over the 20-year study period, France moved from the sixth to the ninth position, chiefly due to a large increase in publications from Asia. However, France remained in third position among European countries and increased its OT production 3-fold between 1998 and 2017. The proportion of OT articles from France that ranked among the top 1% most cited articles increased by 65% from 2008-2012 (20 articles) to 2013-2017 (33 articles), and the proportion in the top 10% increased by 31.8% (211 in 2008-2012 and 278 in 2013-2017). This rate of progression was faster than in any of the other western countries. Between 1998-2011 and 2012-2017, the contribution of French OT to publication output showed a 1.56-fold greater increase than did the contribution of OT to the worldwide volume of scientific medical publications.
    DISCUSSION: OT publications from France have kept pace with the steady increase seen worldwide over the last 20years. Although the US and UK remain in the lead, and despite the considerable growth in the output of Asian countries, France occupies a prominent position on the international OT scene. The creation of OTSR has elevated the international profile of French OT centres.

      PURPOSE: In the current cultural climate, gender disparity is a topical and contentious issue. In academic medicine, there is an underrepresentation of female faculty in leadership positions with lower research output and fewer grant awards. We study the gender differences in faculty rank, leadership positions, and research output among chest radiologists in North America.MATERIALS AND METHODS: A list of clinical faculty at radiology programs in North America was obtained using the FREIDA database and program websites. Demographic information and data pertaining to academic rank, peer-reviewed publications, and research productivity of each chest radiologist was obtained from Doximity and SCOPUS databases.
    RESULTS: Four hundred ten (281 male:129 female) academic chest radiologists were included. Females were underrepresented at senior faculty level accounting for 18.8% (n = 21) of full, 29.2% (n = 21) of associate and 40.7% (n = 61) of assistant professors. 23.1% (n = 14) of department chiefs were women. Women were more likely to occupy a faculty position in chest radiology in Canada than in US (P < 0.05). The median H-index, and numbers of publications and citations were lower for females than male faculty (P < 0.05). Male faculty had more years of experience - median of 19 years, 16.5 years for females (P < 0.05).
    CONCLUSIONS: Gender disparity exists in chest radiology with similar male predominance in terms of senior faculty rank, leadership roles, and research productivity to other medical specialties. The observed deficiency of research and scholarly output among female chest radiologists and the paucity of aspirational female radiologists in senior academic/leadership positions are factors which perpetuate this gender disparity and contribute to persistence of the gender pay gap.

      Background: With the increasing development and use of mobile technologies, an increasing amount of research on mobile health is being conducted. The purpose of the study was to capture the trends in mHealth research by mining terms related to medical conditions, interventions, study populations, and the relationships between these terms.Methods: This study analyzed 5,600 journal articles published in Web of Science from 2008 to 2018. Using text mining techniques, a total of 39,292 terms extracted from the titles and abstracts of the journal articles were independently reviewed to identify meaningful terms related to medical conditions, interventions, and study populations.
    Results: A total of 48 different types of medical conditions were identified in the dataset. Mood disorders appeared to be the most frequently identified medical condition in mHealth research. Thirty interventions were identified. Cell phone-, SMS-, and Internet-based interventions appeared to be the most prominent types, and "female" appeared to be the most frequently identified term related to the studied population. Females appeared to have been studied in the widest range of medical conditions, including pregnancy issues, overnutrition, neoplasms, and AIDS. Older adults were the least studied population in mHealth.
    Conclusions: Knowledge gaps that have not been explored in previous studies in mHealth research were identified, which should be addressed by researchers.

      AIM: To measure productivity in scientific publications of teachers of the Faculty of Medicine and Pharmacy of Casablanca (FMPC).METHODS: This is a descriptive bibliometric study of the publications of the FMPC, indexed in the Medline and Scopus databases, between 2008 and 2017. Articles of physicians affiliated to the FMPC or its university hospital center were included in this study.
    RESULTS: With 1041 articles, the average scientific productivity of the FMPC was 38 articles / 100 teachers-year. These articles were published in 244 journals of which 18% in Pan African Medical Journal and 67% in French. In 58% of the articles, the type was "case reports". Dermatology and Genetics were the most prolific medical disciplines with 122 and 76 articles respectively. In surgery, Oto-Rhino-Laryngology and Gynecology-Obstetrics ranked first, with respectively 75 and 60 articles. The impact factor of the journals that published the articles of the FMPC ranged from 0.05 to 26.56 and was less than two in 84% of the cases. National and international scientific collaboration was 2.6% and 6.4% respectively.
    CONCLUSION: The publication at the FMPC was largely unproductive in English-language journals with a high impact factor. Training in scientific medical writing would be a priority for faculty development and institutional visibility of the FMPC.

      Objectives: Mental health is a less frequently explored area of medical research as both developing and developed countries lack competent human resources and funding for this purpose. Reviewing mental health research can help medical professionals appreciate the progress of understanding and identify problems in this area. This systematic review examined the status of mental health research carried out in medical education institutions and tertiary healthcare hospitals across Pakistan over the past 70 years.Methods: PubMed® (National Library of Medicine, Bethesda, Maryland, USA), was searched for articles published between 1947 and 2017 related to mental health with an emphasis on the exclusive affiliation of the first author with a medical college in Pakistan.
    Results: A total of 118 articles were included in this study. The number of published research-based studies has increased steadily over the past years. However, there are indicators of a lack of quality research, such as no declaration of conflict of interest or the identification of a funding source and a general lack of publications in a journal with a high impact factor.
    Conclusion: The findings of this study have shown a steady improvement in the quantity and quality of mental health research conducted in Pakistani medical colleges/universities. However, a lack of funding, training and faculty induction policies may be hindering the establishment of a research culture and contributing to the slow progression of mental health research in Pakistan.
