      Bibliometric indicators are increasingly used to evaluate individual scientists-as is exemplified by the popularity of the many other publication and citation-based indicators used in evaluation. These indicators, however, cover at best some of the quality dimensions relevant for assessing a researcher: productivity and impact. At the same time, research quality has more dimensions than productivity and impact alone. As current bibliometric indicators are not covering various important quality dimensions, we here contribute to developing better indicators for those quality dimensions not yet addressed. One of the quality dimensions lacking valid indicators is an individual researcher's independence. We propose indicators to measure different aspects of independence: two assessing whether a researcher has developed an own collaboration network and two others assessing the level of thematic independence. Taken together they form an independence indicator. We illustrate how these indicators distinguish between researchers that are equally productive and have a considerable impact. The independence indicator is a step forward in evaluating individual scholarly quality.

      OBJECTIVE:: The Centers for Disease Control and Prevention's Prevention Research Centers (PRCs) collaborate on public health activities with community agencies and organizations. We evaluated these collaborations by studying the relationships between co-authors from the PRCs and community agencies that published at least 1 article together in the first year of the program.METHODS:: We identified all the authors of articles published by PRCs and collaborating members in peer-reviewed journals between September 2014 and September 2015 and constructed a network showing the links between and among all the authors. We characterized the network with 4 measures of social structure (network components, network density, average clustering coefficient, average distance) and 3 measures of individual author performances (degree-, betweenness-, and closeness-centrality).
    RESULTS:: The 413 articles had 1804 individual authors and 7995 co-authorship relationships (links) in 212 peer-reviewed journals. These authors and co-authors formed 44 separate, nonoverlapping groups (components). The largest "giant" component containing most of the links involved 66.3% (n = 1196) of the authors and 73.7% (n = 5889) of the links. We identified 136 "information brokers" (authors with high closeness centrality: those who have the shortest links to the most authors). Two authors with high betweenness centrality (who had the highest number of co-authors; 104 and 107) had the greatest ability to mediate co-authorships. Network density was low; only 0.5% of all potential co-authorships were realized (7995 actual co-authorship/1 628 110 potential co-authorships).
    CONCLUSION:: Information brokers and co-authorship mediators should be encouraged to communicate more with each other to increase the number of collaborations between network members and, hence, the number of co-authorships.

      BACKGROUND: To date, implementation science has focused largely on identifying the individual and organizational barriers, processes, and outcomes of knowledge translation (KT) (including implementation efforts). Social network analysis (SNA) has the potential to augment our understanding of KT success by applying a network lens that examines the influence of relationships and social structures on research use and intervention acceptability by health professionals. The purpose of this review was to comprehensively map the ways in which SNA methodologies have been applied to the study of KT with respect to health professional networks.METHODS: Systematic scoping review methodology involved searching five academic databases for primary research on KT that employed quantitative SNA methods, and inclusion screening using predetermined criteria. Data extraction included information on study aim, population, variables, network properties, theory use, and data collection methods. Descriptive statistics and chronology charting preceded theoretical analysis of findings.
    RESULTS: Twenty-seven retained articles describing 19 cross-sectional and 2 longitudinal studies reported on 28 structural properties, with degree centrality, tie characteristics (e.g., homophily, reciprocity), and whole network density being most frequent. Eleven studies examined physician-only networks, 9 focused on interprofessional networks, and 1 reported on a nurse practitioner network. Diffusion of innovation, social contagion, and social influence theories were most commonly applied.
    CONCLUSIONS: Emerging interest in SNA for KT- and implementation-related research is evident. The included articles focused on individual level evidence-based decision-making: we recommend also applying SNA to meso- or macro-level KT activities. SNA research that expands the range of professions under study, examines network dynamics over time, extends the depth of analysis of the role of network structure on KT processes and outcomes, and employs mixed methods to triangulate findings, is needed to advance the field. SNA is a valuable approach for evaluating key network characteristics, structures and positions of relevance to KT, implementation, and evidence informed practice. Examining how network structure influences connections and the implications of those holding prominent network positions can provide insights to improve network-based KT processes.

      INTRODUCTION: The purpose of this study is to assess how the Hirsch Index (h-index) and other academic metrics change over time for academic minimally invasive surgeons (MIS).METHODS: Through the Fellowship Council's website, MIS program-directors and associate program-directors were identified in 2017 and again in 2018. Using the Scopus database, the number of publications, citations, self-citations, and h-indices were calculated.
    RESULTS: A total of 222 surgeons were included. The median increase of publications, citations, and h-index were 4, 134, and 1, respectively. 75% of surgeons (166/222) saw their h-index increase. In 2017, 26% of surgeons (57/222) had an increase of their h-index due to self-citation. One-year later, 35% of those surgeons (20/57) no longer demonstrated that change.
    CONCLUSION: Self-citation remains infrequent within MIS. The h-index of most surgeons will increase over one-year. Many surgeons demonstrating an increase in h-index due to self-citation will see that change eliminated over time.

      PURPOSE: To investigate and compare the h-indices of the editorial board members of ophthalmic subspecialty journals.STUDY DESIGN: Descriptive Cross Sectional Research.
    METHODS: Bibliometric indices were calculated for the editorial board members of seven ophthalmic subspecialty journals. Correlations between the median h-indexes and journal impact factors (JIF), average citations per article and JIF, and publication count and JIF were analyzed.
    RESULTS: The median h-indices of the board members of Retina, Journal of Glaucoma, Journal of Cataract and Refractive Surgery, Cornea, Ophthalmic Plastic and Reconstructive Surgery, Journal of Neuroophthalmology and Journal of the American Academy of Pediatric Ophthalmology and Strabismus (J AAPOS) were 34, 26, 23, 17, 15, 14 and 13, respectively. H-indices and publication count were correlated with JIF (P<0.05, for each).
    CONCLUSION: The board members of Retina have the highest h-index and average citations per article, and J AAPOS have the least. These data provide useful benchmarks for comparison of the various subspecialty areas in ophthalmology.

      BACKGROUND:: The hypothesis that bipolar disorder presents before puberty with atypical mania has proved to be controversial. Published academic perspectives on the validity of Paediatric Bipolar Disorder (PBD) appear to vary between the United States and the rest of the world.METHODS:: We examined the perspectives of articles citing four seminal articles. The citing articles were grouped as either supportive or non-supportive of the PBD hypothesis, and the perspectives of the articles by US authors were compared with those by non-US authors.
    RESULTS:: There were 787 citing articles commenting on PBD, mostly published in US-based journals. Most authors were affiliated with several US institutions. Among the 624 articles with US authorship, the majority (83%) supported PBD. Of the 163 articles by non-US authors, most (60%) supported the traditional view that bipolar disorders are rare before mid-adolescence. Published academic perspectives in favour of the PBD hypothesis are mostly concentrated in several US institutions.
    CONCLUSION:: There is majority support for PBD among citing articles from the United States, whereas the traditional perspective predominates in articles from most other countries.

      PURPOSE: The impact of academic journals on scientific activity can be measured using different approaches. The aim of this study was to assess the leading anesthesia journals as springboards for new developments in the field of anesthesia.METHODS: The selection of the topics for analysis was based on the degree of increase in the number of articles on a topic that was at the center of specialty interest during 1966-2015. The assessment of a journal's response to a new development was made by measuring the number of initial articles on a related topic. Six leading anesthesia journals were assessed collectively and individually as to whether their responses to new developments were prompt and prominent.
    RESULTS: The role of the leading specialty journals in presentation of 28 topics related to prominent new developments in anesthesia was found to depend on the nature of topics and the type of articles. Compared with all PubMed journals publishing articles associated with anesthesia in 1966-2015, the six leading anesthesia journals published 43% of drug-related research articles, 30% of technique-related research articles, and 16% of both drug- and technique-related review articles. Regarding initial publications (on new topics), this group of six journals contributed comparably more articles: from 43% to 84% of drug-related research articles, from 30% to 49% of technique-related research articles, from 16% to 33% of drug-related review articles, and from 16% to 25% of technique-related review articles. The approximate doubling of the shares demonstrates the dominance of this group of journals in the swiftness response to new anesthesia developments. The promptness of reaction to new developments in anesthesia of each of the six leading anesthesia journals was assessed (the combination of drug- and technique-related articles) based on the number of articles published among the first (first 5 plus next 30) on all 28 topics. The ranking order of four journals (with the highest number of all 1966-2015 articles) regarding early publications was (from high to low): Anesthesia & Analgesia, British Journal of Anaesthesia, Anesthesiology, and Anaesthesia.
    CONCLUSION: This study assesses six leading anesthesia journals for their function as springboards for new developments in anesthesia over the past 50 years. The dominance of leading journals in initial publications on 28 drug-related and technique-related topics was clearly demonstrated. The results also indicate the possibility of using promptness of response to new advances for quantitative assessment of this aspect of a journal's contribution to the specialty.

      Because the Amazon rain forest is ecologically relevant on a global scale, we applied scientometric techniques to integrate studies dealing with mercury research in this unique ecosystem between 1991 and 2017. Using a combination of co-authorship and co-citation analyses, keyword mapping and overlay visualization of topics in the field, this article identified three major areas in the 26-year period of mercury research: (1) human exposure to mercury (artisanal small-scale gold mining-ASGM) and methylmercury through fish consumption, and their respective risks for human health; (2) mercury accumulation in the environment and its relation to ASGM and atmospheric concentration; and (3) mercury geochemistry and its presence in soils, sediments, and water. The paper also identified the leading institutions related to the published research and respective influential scholars in the context of this study. Overall, the analyses revealed patterns of convergence and divergence between authors, specialization, and interdisciplinary engagement in mercury investigation, thus highlighting strengths and weaknesses of research topics in the field. This scientometric approach could be a useful tool to monitor/assess the implementation of the Minamata Convention.

      The term 'life-history theory' is a familiar label in several disciplines. Life-history theory has its roots in evolutionary models of the fitness consequences of allocating energy to reproduction, growth and self-maintenance across the life course. Increasingly, the term is also used in the conceptual framing of psychological and social-science studies. As a scientific paradigm expands its range, its parts can become conceptually isolated from one another, even to the point that it is no longer held together by a common core of shared ideas. Here, we investigate the literature invoking the term 'life-history theory' using quantitative bibliometric methods based on patterns of shared citation. Results show that the literature up to and including 2010 was relatively coherent: it drew on a shared body of core references and had only weak cluster divisions running along taxonomic lines. The post-2010 literature is more fragmented: it has more marked cluster boundaries, both between the human and non-human literatures, and within the human literature. In particular, two clusters of human research based on the idea of a fast-slow continuum of individual differences are bibliometrically isolated from the rest. We also find some evidence suggesting a decline over time in the incidence of formal modelling. We point out that the human fast-slow continuum literature is conceptually closer to the non-human 'pace-of-life' literature than it is to the formal life-history framework in ecology and evolution.

      BACKGROUND: With the widespread application of a robot to surgery, growing literature related to robotics in surgery (RS) documents widespread concerns from scientific researchers worldwide. Although such application is helpful to considerably improve the accuracy of surgery, we still lack the understanding of the multidiscipline-crossing status and topic distribution related to RS.OBJECTIVE: The aim of this study was to detect the interdisciplinary nature and topic hotspots on RS by analyzing the current publication outputs related to RS.
    METHODS: The authors collected publications related to RS in the last 21 years, indexed by the Web of Science Core Collection. Various bibliometric methods and tools were used, including literature distribution analysis at the country and institution level and interdisciplinary collaboration analysis in the different periods of time. Co-word analysis was performed based on the keywords with high frequency. The temporal visualization bar presented the evolution of topics over time.
    RESULTS: A total of 7732 bibliographic records related to RS were identified. The United States plays a leading role in the publication output related to RS, followed by Italy and Germany. It should be noted that the Yonsei University in South Korea published the highest number of RS-related publications. Furthermore, the interdisciplinary collaboration is uneven; the number of disciplines involved in each paper dropped from the initial 1.60 to the current 1.31. Surgery; Engineering; Radiology, Nuclear Medicine, and Medical Imaging; and Neurosciences and Neurology are the 4 core disciplines in the field of RS, all of which have extensive cooperation with other disciplines. The distribution of topic hotspots is in imbalanced status, which can be categorized into 7 clusters. Moreover, 3 areas about the evolution of topic were identified, namely (1) the exploration of techniques that make RS implemented, (2) rapid development of robotic systems and related applications in surgery, and (3) application of a robot to excision of tissues or organs targeted at various specific diseases.
    CONCLUSIONS: This study provided important insights into the interdisciplinary nature related to RS, which indicates that the researchers with different disciplinary backgrounds should strengthen cooperation to publish a high-quality output. The research topic hotspots related to RS are relatively scattered, which has begun to turn to the application of RS targeted at specific diseases. Our study is helpful to provide a potential guide to the direction of the field of RS for future research in the field of RS.

      OBJECTIVES: To analyse trends in the academic literature applying complexity science to healthcare, focusing specifically on bibliometric characteristics and indicators of influence.DESIGN: This study reports a bibliometric analysis via a systematic search of the academic literature applying complexity science to healthcare.
    METHOD: A search of four academic databases was performed on 19 April 2018. Article details were downloaded and screened against inclusion criteria (peer-reviewed journal articles applying complexity science to healthcare). Publication and content data were then collected from included articles, with analysis focusing on trends over time in the types and topics of articles, and where they are published. We also analysed the influence of this body of work through citation and network analyses.
    RESULTS: Articles on complexity science in healthcare were published in 268 journals, though a much smaller subset was responsible for a substantial proportion of this literature. USA contributed the largest number of articles, followed by the UK, Canada and Australia. Over time, the number of empirical and review articles increased, relative to non-empirical contributions. However, in general, non-empirical literature was more influential, with a series of introductory conceptual papers being the most influential based on both overall citations and their use as index references within a citation network. The most common topics of focus were health systems and organisations generally, and education, with recent uptake in research, policy, and change and improvement.
    CONCLUSIONS: This study identified changes in the types of articles on complexity science in healthcare published over time, and their content. There was evidence to suggest a shift from conceptual work to the application of concrete improvement strategies and increasingly in-depth examination of complex healthcare systems. We also identified variation in the influence of this literature at article level, and to a lesser extent by topic of focus.

      OBJECTIVE: To explore how out-of-hours primary healthcare services (OOHS) are represented in UK national newspapers, focusing on content and tone of reporting and the use of personal narratives to frame stories.DESIGN: A retrospective cross-sectional quantitative content analysis of articles published in 2005, 2010 and 2015.
    DATA SOURCES: Nexis database used to search 10 UK national newspapers covering quality, middle-market and tabloid publications.
    INCLUSION/EXCLUSION CRITERIA: All articles containing the terms 'out-of-hours' (≥3 mentions per article) or ('NHS 24' OR 'NHS 111' OR 'NHS Direct') AND 'out-of-hours' (≥1 mention per article) were included. Letters, duplicate news items, opinion pieces and articles without a substantial portion of the story (>50% of an article's word count, as judged by researchers) concerning OOHS were excluded.
    RESULTS: 332 newspaper articles were identified: 113 in 2005 (34.1%), 140 in 2010 (42.2%) and 79 in 2015 (23.8%). Of these, 195 (58.7%) were in quality newspapers, 99 (29.8%) in middle-market and 38 (11.3%) in tabloids. The most commonly reported themes were OOHS organisation, personal narratives and telephone triage. Stories about service-level crises and personal tragedy, including unsafe doctors and missed or delayed identification of rare conditions, predominated. The majority of articles (252, 75.9%) were negative in tone. This was observed for all included newspapers and by publication genre; middle-market newspapers had the highest percentage of negative articles (Pearson χ2=35.72, p<0.001). Articles presented little supporting contextual information, such as call rates per annum, or advice on how to access OOHS.
    CONCLUSION: In this first reported analysis of UK national newspaper coverage of OOHS, media representation is generally negative in tone, with frequent reports of 'negative exemplars' of OOHS crises and fatal individual patient cases with little or no contextualisation. We present recommendations for the future reporting of OOHS, which could apply to the reporting of healthcare services more generally.

      In undergraduate biology laboratory courses, laboratory reports can be a useful tool for teaching scientific writing, integration of source material, and information literacy; however, these teaching objectives are at times undermined by students' plagiarism. Laboratory instructors often use similarity-matching software to detect plagiarism in laboratory reports, yet similarity hits detected with such software remain poorly characterized. In the upper division molecular biology laboratory course described here, Turnitin® routinely detected dozens of similarity hits in laboratory reports. To determine whether this abundance of similarity hits was indicative of widespread plagiarism, we analyzed similarity hits detected in 255 laboratory reports written by 135 students. Only a small minority of Turnitin® similarity matches were problematic, but over half of the laboratory reports contained at least one problem with incorporation of scientific sources (e.g., laboratory manual and scientific articles). We identified four common types of such writing problems: patchwriting, technical parroting, copying, and falsification of sources. In 18% of the laboratory reports, we detected an alarmingly superficial use of primary literature. Most of the source incorporation problems did not rise to the level of plagiarism. As a result of this study, we recommend changes in scientific writing instruction and a transition to laboratories providing more authentic research experiences. © 2019 International Union of Biochemistry and Molecular Biology, 2019.

      This report presents a review of the Malaysian Journal of Medical Sciences' (MJMS) performance status throughout 2017, which covers the submission pattern of original manuscripts by month, the geographical distribution of submitting authors, the types of manuscripts and overall acceptance/rejection rates. As the years progress, MJMS continues to receive an escalating number of manuscript submissions. This contributes to an ever-increasing workload, which makes administrative tasks continually more challenging. Although the manuscript submission platform seeks to minimise the pre-publication workload of the journal administrator, it is still a time-consuming task, particularly when authors seek exclusive attention for their submitted manuscripts.

      INTRODUCTION: Health care professionals rely on annual general meetings (AGMs) to obtain up-to-date information and practice guidelines relevant to their specialty. The majority of such information at meetings is presented through abstract sessions. However, the quality of the evidence presented during such abstract sessions is unclear. Standardized measures were applied to assess the quality of evidence of abstracts presented at the Canadian Society of Nephrology AGM over a 5-year period.METHODS: Two authors independently reviewed all CSN AGM abstracts presented from 2012 to 2016. Using a schema published in 2011 by the Oxford Centre for Evidence-Based Medicine (OCEBM), each abstract was subsequently ranked based on the quality of evidence. Schema categories ranged from level I, representing the highest evidence quality, to level V, representing the lowest. The number of authors and the authors' institution affiliations were also collected from the abstracts, where available, or if affiliations were unclear, an internet search of the author was performed.
    RESULTS: Six hundred forty-two articles were screened. In total, 70% (n = 450) met the inclusion criteria. When assessed, 15% of articles were level I (highest quality), 17% level II, 53% level III, 12% level IV, and 3% level V (lowest quality). A Jonckheere-Terpstra test demonstrated a significant trend of increasing quality of evidence (P < .05) and collaboration (P < .005) over the 5-year study period. There was a significant correlation between level of evidence and collaboration across years reviewed in the study, rs(98) = -0.226, P < .001.
    DISCUSSION: The results indicate a consistent increase in quality of evidence and collaborative submissions over time. To the authors' knowledge, this is the first assessment and analysis of AGM presentation quality within internal medicine and its subspecialties. Documenting and monitoring changes in the quality of evidence with a standardized framework may offer valuable insight pertaining to the medical field and the research community.

      The Clinical and Translational Science Awards (CTSA) program sponsors an array of innovative, collaborative research. This study uses complementary bibliometric approaches to assess the scope, influence, and interdisciplinary collaboration of publications supported by single CTSA hubs and those supported by multiple hubs. Authors identified articles acknowledging CTSA support and assessed the disciplinary scope of research areas represented in that publication portfolio, their citation influence, interdisciplinary overlap among research categories, and characteristics of publications supported by multihub collaborations. Since 2006, CTSA hubs supported 69,436 articles published in 4,927 journals and 189 research areas. The portfolio is well distributed across diverse research areas with above-average citation influence. Most supported publications involved clinical/health sciences, for example, neurology and pediatrics; life sciences, for example, neuroscience and immunology; or a combination of the two. Publications supported by multihub collaborations had distinct content emphasis, stronger citation influence, and greater interdisciplinary overlap. This study characterizes the CTSA consortium's contributions to clinical and translational science, identifies content areas of strength, and provides evidence for the success of multihub collaborations. These methods lay the foundation for future investigation of the best policies and priorities for fostering translational science and allow hubs to understand their progress benchmarked against the larger consortium.

      Applied ecology is one of the most important scientific and technological tools for natural resources management and environment protection. Under the current situation of natural resource shortage, serious environmental pollution, and ecosystem degradation, understanding the theoretical basis, research methods and research hotspots of international studies on applied ecology is of great significance for consolidating the knowledge base, indicating the research direction, defining the strategic position of China's studies on applied ecology. Based on the principle of bibliometrics and information visualization software (CiteSpace and Carrot2), we took two document datasets as research objects which were searched from Web of Science based on different search strategies in the field of international studies on applied ecology from 1980 to 2018. We analyzed the spatial and temporal distribution of the literature, the core research forces, the evolution and frontier trend of research hotspots from three dimensions, i.e. research carrier, research strength, and research content. Our results could reveal its evolutionary trajectory, research status and development trend and provide reference for future studies on applied ecology in China.

      OBJECTIVES:  To identify major research subjects and trends in medical informatics research based on the current set of core medical informatics journals.METHODS:  Analyzing journals in the Web of Science (WoS) medical informatics category together with related categories from the years 2013 to 2017 by using a smart local moving algorithm as a clustering method for identifying the core set of journals. Text mining analysis with binary counting of abstracts from these journals published in the years 2006 to 2017 for identifying major research subjects. Building clusters based on these terms for the complete time period as well as for the periods 2006-2008, 2009-2011, 2012-2014, and 2015-2017 for identifying trends.
    RESULTS:  The identified cluster includes 17 core medical informatics journals. By text mining of these journals, 224,992 different terms in 14,414 articles were identified covering 550 specific key terms. Based on these key terms five clusters were identified: "Biomedical Data Analysis," "Clinical Informatics," "EHR and Knowledge Representation," "Mobile Health," and "Organizational Aspects of Health Information Systems." No shifts in the clusters were observed between the first two 3-year periods. In the third period, some terms like "mobile phone," "mobile apps," and "message" appear. Also, in the third period, a "Clinical Informatics" cluster appears and persists in the fourth period. In the fourth period, a rearrangement of clusters was observed.
    CONCLUSIONS:  Beside classical subjects of medical informatics on organizing, representing, and analyzing data, we observed new developments in the context of mobile health and clinical informatics. These subjects tended to grow over the past years, and we can expect this trend to continue.

      Objective: In recent years, citation analysis tools provide many devices for finding or computing the citation score or impact factor for journals. It is important for the researchers to identify good journals for collecting research ideas discussed. A journal with a good impact factor value is preferably referred to by many researchers. In this research work, the author proposes a system for ranking journals on the basis of ideas and results cited in other papers. Methods: The work involves the cited content extractor for extracting the descriptive features mentioned about the cited paper. The cited content refers to the content in the article written by a citing paper and relating to the cited paper. The ranking system uses a citation score estimator for computing the overall weight of the descriptive cited content relating to a specific paper in the citing papers. The journal ranking system performs classification of the citation content with the evaluation of a citation score. The work that involves the citation content is classified under different categories as positively cited, negatively cited or neutral and unrelated. Results: Then the computed citation score is used for ranking the dealing with research on cancer research journals. The results of the ranking journals indicate that the particular ranked journal has been cited in the literature of many journals with a good descriptive content. Journal ranking system can be considered as a well-organized tool for ranking the cancer research scientific journal based on citation content and citation counting. Conclusion: This experimental cancer journal ranking method increases accuracy and effectiveness by using the citation content when compared with PageRank and HITS.

      BACKGROUND: As India's accredited social health activist (ASHA) community health worker (CHW) programme enters its second decade, we take stock of the research undertaken and whether it examines the health systems interfaces required to sustain the programme at scale.METHODS: We systematically searched three databases for articles on ASHAs published between 2005 and 2016. Articles that met the inclusion criteria underwent analysis using an inductive CHW-health systems interface framework.
    RESULTS: A total of 122 academic articles were identified (56 quantitative, 29 mixed methods, 28 qualitative, and 9 commentary or synthesis); 44 articles reported on special interventions and 78 on the routine ASHA program. Findings on special interventions were overwhelmingly positive, with few negative or mixed results. In contrast, 55% of articles on the routine ASHA programme showed mixed findings and 23% negative, with few indicating overall positive findings, reflecting broader system constraints. Over half the articles had a health system perspective, including almost all those on general ASHA work, but only a third of those with a health condition focus. The most extensively researched health systems topics were ASHA performance, training and capacity-building, with very little research done on programme financing and reporting, ASHA grievance redressal or peer communication. Research tended to be descriptive, with fewer influence, explanatory or exploratory articles, and no predictive or emancipatory studies. Indian institutions and authors led and partnered on most of the research, wrote all the critical commentaries, and published more studies with negative results.
    CONCLUSION: Published work on ASHAs highlights a range of small-scale innovations, but also showcases the challenges faced by a programme at massive scale, situated in the broader health system. As the programme continues to evolve, critical comparative research that constructively feeds back into programme reforms is needed, particularly related to governance, intersectoral linkages, ASHA solidarity, and community capacity to provide support and oversight.

      OBJECTIVES: To quantify the research contribution related to Ramadan fasting and diabetes.METHODS: We searched for the combination of "Ramadan" and Diabetes" in the title, abstract and keywords in the Scopus database between 1989 and 2018. Articles were analysed for standard bibliometric methodology and VOSviewer was used to construct bibliometric diagrams.
    RESULTS: The total number of retrieved articles was 424 articles; 112 were "Open Access". Two-thirds of articles covered original research. Articles were published in medical journals of varying influence. UK-based authors and affiliated institutions were dominant. A single author has an evident dedication to Ramadan research whereas for many authors it Ramadan research was just one aspect of their academic interest. The number publications and the extent of international collaborations were lower than expected, given the world-wide practice of Ramadan fasting by many populations with an increased prevalence of diabetes. The need to share experiences and generalizable conclusions.
    CONCLUSIONS: This is the first bibliometric study on diabetes in Ramadan. It is a good starting point to evaluate gaps in research activity in the field and should help identify future research directions and foster more collaboration.

      Background Scientific publications are the primary vehicle for the distribution of scientific findings, but there has been limited research on literature topic surveillance. We sought to identify and characterize the most commonly published topic domains in the hand surgery literature. Methods We performed a 6-month hypothesis testing phase to identify the most frequently published topics in three hand surgery journals: Hand, The Journal of Hand Surgery (American), and The Journal of Hand Surgery (European). We reviewed all of the published articles in these journals from June 2010 to May 2015 to identify and characterize publications related to the three most common topic domains. Results A total of 2,146 articles were published during the 5-year study period. The three most frequent topics domains included distal radius (DR) (11% of all articles), flexor tendon (FT) (9%), and carpal tunnel (CT) (7.5%). These subjects accounted for a total of 584 articles (27% of all publications) and 3,014 published pages during the study period. FT, CT, and DR publications were cited on average 2.3 times per year (2.5, 2.4, and 2.0, respectively). Conclusion A small subset of topic domains makes up a significant proportion of scientific publications in hand surgery.

      Introduction: Robotic assisted surgery (RAS) is one of the most recent surgical approaches that has quickly been adopted by the pediatric urology community. Over the last decade, a vast amount of manuscripts has been published, supporting the safety and applicability of RAS in the pediatric population. The quality of published literature about this innovative technology remains supported by case-reports and retrospective case-series. Historical behavior of literature productivity and implementation of laparoscopy followed a similar trend. We present the historical publication uptake of RAS in pediatric urology and other surgical disciplines using a bibliometric comparison of the most cited manuscripts. Materials and Methods: A systematic search and review of the literature was undertaken by the authors. Literature search was performed in OVID, PubMed, EMBASE, Scopus, Web of Science, and Google Scholar. The search period included all publications between 1985 and June 2018. All languages were included. Data analysis for graphical representation was performed using VOSviewer® version 1.6.8 and Impact Index Analysis was used to adjust the citations by the time since publication. Results: A total of 1,014 titles were identified. After applying exclusion criteria, 200 papers were included for the RAS arm and 402 for the laparoscopic one. Case-series was the most common type of publication. Average citations for laparoscopic manuscripts was 23 (SD ± 31) and for RAS was 20 (SD ± 31.5). The impact index analysis showed an average of 95 (SD ± 167) for laparoscopic manuscripts vs. 66 (SD ± 101) for RAS. The laparoscopic manuscript with the highest citation count had 199 citations with an impact index of 12.1. And the RAS manuscript with the highest citation count had 280 citations and an impact index of 4.3. Conclusion: Literature productivity in pediatric laparoscopic and RAS has quickly grown. Pediatric Urologists play a key role in the introduction of this innovative tool. Literature supporting its implementation and future consolidation requires to focus on increasing the level of evidence.

      In recent years, the algae-bacteria symbiotic system has played a significant role in the sustainable development of wastewater treatment. With the continuous expansion of research outputs, publications related to wastewater treatment via algal-bacterial consortia appear to be on the rise. Based on SCI-EXPANDED database, this study investigated the research activities and tendencies of algae-bacteria symbiotic wastewater treatment technology by bibliometric method from 1998 to 2017. The results indicated that environmental sciences and ecology was the most productive subject categories, followed by engineering. Bioresource Technology was the most prominent journal in this field with considerable academic influence. China (146), USA (139) and Spain (76) had the largest amount of publications. Among them, USA was in a leading position in international cooperation, with the highest h-index (67) in 79 countries/territories. The cooperation between China and USA was the closest. The cooperative publishing rate of the Chinese Academy of Sciences was 83.33%, but most of them were in cooperation with domestic institutions, while international cooperation was relatively limited. Methane production, biofuel production, and extracellular polymeric substance were future focal frontiers of research, and this field had gradually become a multi-perspective and inter-disciplinary approach combining biological, environmental and energy technologies.

      Background: The prevalence, incidence, and mortality rates of tuberculosis (TB) have declined steadily in Korea since 1965. This study aimed to identify the characteristics and provide quantitative analysis of published medical literatures on TB written by researchers based in Korea.Methods: We conducted a systematic literature search via the Web of Science database for articles in Science Citation Index (Expanded) journals, on TB, and published by researchers based in Korea, from inception to 2017. All articles were analyzed by publication year, publishing journal, article type, study design, research institutes, and research funds.
    Results: During the study period, we identified 1,101 articles and included them for analysis. The first was published in 1979, while 105 were published in 2017. Between 1979 and 2017, the compound annual growth rate of TB articles by researchers based in Korea was 13.0%. Among 1,101 articles, 682 (61.9%) were clinical research and 383 (34.8%) were basic research. Studies with cross-sectional design were the most common type among the clinical research, while biochemistry was the most common field among the basic research. The number of articles dealing with diagnostics or treatment has increased significantly, although the number of articles on vaccines, and on operational and public health, has only a slight increase. The Ministry of Health and Welfare of Korea funded studies yielding 178 (20.1%) articles.
    Conclusion: Articles on TB, especially those on clinical aspects, and published by researchers based in Korea have been increasing rapidly since 1979.

      Objective: Evidence-based practice in medical sciences needs to publish confidential evidence that strongly depends on the research publications. This bibliometrics and network analytic study aims to evaluate the research publications of Iranian authors in pharmacology and pharmacy.Methods: Through the pharmacology and pharmacy category of Web of Science (WOS), all published articles affiliated with an Iranian researcher as an author were retrieved. Full records of retrieved articles in the WOS, including author name and affiliation, journal name, citation number, cited references, and keywords, were exported to a plain text file. Network analysis through VOSviewer was used for mapping the characteristics of the retrieved articles. All statistical analyses were done using the Microsoft Excel and SPSS version 25.
    Findings: The total number of Iran's publications (citations) rose from 1557 articles (10,085 citations) in 2000-2009 years to 6271 articles (77791 citations) in 2010-2018 years. Tehran University of Medical Sciences was the most productive university. The total number of RCTs rose from 82 publications in 2000-2009 to 278 publications in 2010-2018. The same numbers for systematic reviews and meta-analyses were four publications in 2000-2009 and 169 publications in 2010-2018. The five major topics of researches in pharmacology and pharmacy were drug delivery, basic pharmacology, oxidative stress, animal study, and molecular aspect of pharmacy.
    Conclusion: This study showed a marked increasing rate of publications and received citations by Iranians in pharmacology and pharmacy. After 2010, the rate of articles in the high-impact journals had growth. Furthermore, research articles in the highest level of evidence were more published by Iranians.

      INTRODUCTION AND OBJECTIVES: The Spanish Society of Cardiology/Spanish Heart Foundation (SEC/FEC) annually awards grants for cardiovascular research projects. Our objective was to analyze the trend in these investments and their resulting scientific production from 2007 to 2012.METHODS: A search of the publications funded by the SEC/FEC was carried out, according to the following inclusion criteria: publication in a journal indexed in MEDLINE or EMBASE, publication date after the grant, authorship by the principal investigator of the grant, and acknowledgment of SEC/FEC funding. The impact factor and subsequent citations of the articles were analyzed (Web of Science).
    RESULTS: A total of 235 grants were awarded (39/y) with an allocation of €3 854 300 (€642 383/y), 37% of them to women. In all, 122 publications resulted from 88 research projects (37%) funded by the SEC/FEC. Up to October 2017, these publications had received 2258 citations in subsequent studies in the Web of Science, with a mean of 18.5 and a median of 8 citations/study.
    CONCLUSIONS: Despite the economic crisis, the mean number and size of the grants awarded by the SEC/FEC increased in the period analyzed. Grants were awarded on an equal opportunity basis to men and women. The bibliometric impact of the funded projects is acceptable, although efforts should be made to improve it.

      BACKGROUND: Scholarly activity in various forms are academic deeds such as researches and research outputs in articles, oral presentations, publications and theses which are disseminated and peer- reviewed.OBJECTIVES: This study aims to assess the level of participation of residents in scholarly activities including their attendance of national and international conferences during residency training.
    METHODS: This was a descriptive cross-sectional study of 81 resident doctors in General and Orthopaedic surgery, who attended the revision courses organized by their Faculties. Self-administered structured questionnaires were used to collect data. Data obtained was analyzed using SPSS version 21.0.
    RESULTS: The mean age of the respondents was 34.1 ± 4.5 years, and age ranged from 26 years to 48 years. The male: female ratio was 12.5:1. The average number of years of respondents in residency programme was 3.9 ± 1.8 years. 80.3% of the residents had participated in research since commencement of their residency. Only 18.5% of the resident doctors had any publications in a peer-reviewed journal. While 51.9% of residents had attended local and national conferences since the beginning of their training, only 17.3% had had oral and/or poster presentations at local conferences. No resident involved in this study had oral or poster presentation done at any of the international conferences attended, despite an attendance rate of 12.3%.
    CONCLUSION: Resident doctors should be encouraged to participate in researches and to publish their works. They should also be encouraged to present their works at conferences.
