      AIM: To analyse the current status and publication trends of funded studies in nursing-related research from 2008 to 2018, available in the Web of Science.DESIGN: A longitudinal bibliometric analysis of publications of funded studies in nursing-related research, obtained from the Web of Science, was conducted.
    METHODS: On 10 May 2019, we accessed 77,772 funded studies (2008-2018) from the Web of Science. Bibliometric methods and indicators were used to classify the publications and summarize the overall number, countries/regions, institutions, journals, and other parameters of the publications.
    RESULTS: The global output of nursing-related funded research publications increased significantly over time. The three leading countries with the highest number of funded publications were the United States, Australia, and the United Kingdom, with the United States accounting for 15 of the top 20 institutions associated with funded publications, which mostly included institutions of higher education. The most common disciplines of these publications were oncology, psychiatry, and paediatrics. The top three journals that published the largest number of nursing-related funded publications were the Journal of Clinical Nursing, the Journal of Advanced Nursing, and the International Journal of Nursing Studies. Keywords with the highest frequency of occurrence included "nurses," "qualitative research," "older people," "quality of life," "depression," "cancer," and "children."
    CONCLUSIONS: Nursing-related research has been drawing increasing attention over the years. Analysing the output of funded publications and monitoring the new dynamics of the international development of academic research in the field of nursing are crucial for determining future directions of nursing-related research development.
    IMPACT: The results of this study will provide a reference for scholars to evaluate the current utilization efficiency of global nursing-related research funding and demonstrate the development and trends in nursing-related research.

      AIM: Bibliometric analyses are common in the literature on different disciplines however limited number of studies focus on scoliosis. Our aim is to make a in-depth bibliometric analysis of scoliosis.MATERIAL AND METHODS: We used Web of Science database to obtain necessary documents for the analyses. Using "scolio*" keyword our search focused on the period 1980-2019. Bibliometric network visualizations and mapping of specific results were done with VOSviewer software.
    RESULTS: Our literature search turned up 9706 publications about scoliosis published between 1980 and 2019. Of these publications, 6975 (71.9%) were journal articles and thus were included in the bibliometric summary. Orthopedics was the most common research area with 4581 articles and 65.67%. Among all countries, the United States of America (USA) with 2327 articles and 33.36% contributed the most publications. Nanjing University in the China with 219 articles, that covers 3.13% of the total literature, had the highest number of publications among institutions. There were 60130 citations in 6975 articles. There were 55 articles with minimum 100 citations. Journal with the most publications about scoliosis is the 'Spine' (number of article: 1628, 23.3%).
    CONCLUSION: This bibliometric analysis can be regarded as a summary and evaluation of global scientific output on scoliosis deformity and a guide for researchers, clinicians and students. Furthermore, provided keyword analysis can aid professionals in the field while planning for new studies.

      BACKGROUND: Publications regarding the 100 top-cited articles in a given discipline are common, but studies reporting the association between article topics and their citations are lacking. Whether or not reviews and original articles have a higher impact factor than case reports is a point for verification in this study. In addition, article topics that can be used for predicting citations have not been analyzed. Thus, this study aims to METHODS:: We searched PubMed Central and downloaded 100 top-cited abstracts in the journal Medicine (Baltimore) since 2011. Four article types and 7 topic categories (denoted by MeSH terms) were extracted from abstracts. Contributors to these 100 top-cited articles were analyzed. Social network analysis and Sankey diagram analysis were performed to identify influential article types and topic categories. MeSH terms were applied to predict the number of article citations. We then examined the prediction power with the correlation coefficients between MeSH weights and article citations.RESULTS: The citation counts for the 100 articles ranged from 24 to 127, with an average of 39.1 citations. The most frequent article types were journal articles (82%) and comparative studies (10%), and the most frequent topics were epidemiology (48%) and blood and immunology (36%). The most productive countries were the United States (24%) and China (23%). The most cited article (PDID = 27258521) with a count of 135 was written by Dr Shang from Shandong Provincial Hospital Affiliated to Shandong University (China) in 2016. MeSH terms were evident in the prediction power of the number of article citations (correlation coefficients  = 0.49, t = 5.62).
    CONCLUSION: The breakthrough was made by developing dashboards showing the overall concept of the 100 top-cited articles using the Sankey diagram. MeSH terms can be used for predicting article citations. Analyzing the 100 top-cited articles could help future academic pursuits and applications in other academic disciplines.

      Objective: We focused on medical informatics journal publications rather than on conference proceedings by comparing and analyzing the data from journals and conferences from a broader perspective. The aim is to summarize the unique contributions of China to medical digitization and foster more multilevel international cooperation.Method: In February 2019, publications from 2008 to 2018 in three major English-language medical informatics journals were retrieved through Scopus, including the journals, namely, International Journal of Medical Informatics (IJMI, international community), JAMIA (United States), and Methods of Information in Medicine (MIM, Europe). Three major Chinese-language journals, namely, China Digital Medicine (CDM), Chinese Journal of Health Informatics and Management (CJHIM), and Chinese Journal of Medical Library and Information Science (CJMLIS), were searched within the major three Chinese literature databases. The datasets were preprocessed using the NLP package on Python, and a smart local moving algorithm was used as a clustering method for identifying the aforementioned journals.
    Result: Between 2008 and 2018, the total number of published papers and H-index of the three English-language journals was 1371 and 67 (IJMI), 1752 and 86 (JAMIA), and 637 and 35 (MIM), respectively. In the same period, the total number of published papers and H-index in the three Chinese-language journals was 6668 and 23 (CDM), 1668 and 22 (CJHIM), and 2557 and 25 (CJMLIS), respectively. IJMI, JAMIA, and MIM received submissions from 82, 59, and 62 countries/regions, respectively. By contrast, the three Chinese journals only received submissions from seven foreign countries. The proportions of authors from institutional affiliations were similar between the three English-language journals (IJMI, JAMIA, and MIM) and CJMLIS because the majority of the authors were from universities (81%, 74%, 73%, and 65.2%), followed by medical institutions (12%, 10%, 9%, and 23.4%) or research institutes (2%, 4%, 10%, and 4.3%). Furthermore, the proportions of the authors from enterprises were low (2%, 6%, 4%, and 0.3%) for all journals. However, the authors in CDM and CJHIM were mainly from medical institutions (50% and 40%), followed by universities (33% and 32%) and research institutes (3% and 4%). In addition, the proportions of enterprises were only 3% and 2%, respectively. Among the top five authors in three English-language journals (ranked in terms of the number of published papers), 100% had doctoral or master's degrees, compared with only 60% in the Chinese journals. Additionally, 28204 different keywords were extracted from the aforementioned papers, covering 275 specific high-frequency key terms. Based on these key terms, four clusters were found in the English literature-"Health and Clinical Information Systems," "Internet and Telemedicine," "Medical Data Statistical Analysis," and "EHRs and Information Management"-and three clusters were found in the Chinese literature: "Hospital Information Systems and EMR," "Library Science and Bibliometrics Analysis," and "Medical Reform Policy and Health Digitization." Only two clusters are similar, and Chinese-language journals focus more on health information in technology and industrial applications than in medical informatics basic research.
    Conclusion: This study provides important insights into the development of medical informatics (MI) in China and Western countries showing that the medical informatics journals of China, the United States, and Europe have distinct characteristics. Specifically, first, compared with the Western journals, the number of papers published in the journals of professional associations in the field of MI in China is large and the application value is high, but the academic influence and academic value are relatively low; second, most of the authors of the Chinese papers are from hospitals, and most of the counterparts in the Western countries are from universities. The proportion of master's or doctoral degrees in the former is also lower than that of the latter; furthermore, regarding paper themes, on the one hand, China MI has no theoretical and basic research on medical data statistics and consumer health based on the Internet and telemedicine; on the other hand, after nearly 10 years of hospital digital development, China has fully used the latecomer and application advantages in hospitals and, through extensive international cooperation, has made significant advancements in and contributions to the development of medical information.

      BACKGROUND: Inflammatory bowel disease (IBD) represents a series of digestive system abnormalities and parenteral manifestations. Stem cell therapy has been regarded as a promising treatment for IBD.METHODS: We searched Web of Science Core Collection for publications of interest from 1991 to 2019. Publication performance was analyzed using several bibliometric parameters, including Statplanet to reveal the geographic distribution of the publications, VOSviewer to identify the research landscape of hot topics, and CiteSpace to show keywords with the strongest citation bursts.
    RESULTS: A total of 1230 publications were identified, of which 674 articles were analyzed further. The United States was the most productive country and Spanish researchers published the highest quality articles. At a journal level, Gastroenterology published the greatest number of articles, while articles from Gut had the highest citation number. Results from the research landscape analysis of hot topics and the top 20 terms with the strongest citation bursts indicated that animal experiments, immunocytes, intestinal epithelial cells, cytokine expression, and clinical efficacy were the main focuses of research.
    CONCLUSION: Stem cell therapy for IBD is currently receiving increasing attention by researchers, with focuses on animal experiments, immunocytes, intestinal epithelial cells, cytokine expression, and clinical efficacy.

      Context: Multimorbidity is frequently seen in primary care. We aimed to identify and analyze publications on multimorbidity, including those that most influenced this field.Method: A bibliometric analysis of publications from 2005 to 2019 in the PubMed database containing "multimorbidity" or "multi-morbidity" identified with the tool iCite. We analyzed the number of publications, total citations, the article-level metric Relative Citation Ratio (RCR), type of study, and journals with the most cited articles.
    Results: The number of publications using "multimorbidity" has continuously increased since 2005 (2005-2009: 138; 2010-2014: 823; 2015-2019: 3068). The median number of total citations per article was 3. The median RCR was 1.04. Articles with RCR at or above the 97th percentile (RCR = 7.43) were analyzed in detail (n = 104). In 34 publications of this subgroup (33%), the word multimorbidity was used but was not the subject of study. The remaining top 70 publications included 32 observational studies, 22 reviews, five guideline statements, three analysis papers, two randomized trials, three qualitative studies, two measurement development reports, and one conceptual framework development report. The publications were produced by authors from 32 countries. They were published in 37 different journals, ranging from one to four articles in the same journal.
    Conclusions: We found a continuous increase in the number of publications about multimorbidity since 2005. However, our study suggests that the numbers should be considered only a general trend because multimorbidity was not the main subject in 33% of publications in a subgroup of 104 analyzed in detail.

      Background: Despite governmental interventions, the Gulf Cooperation Council (GCC) region continues to experience higher road traffic crash and fatality rates relative to Western nations. This trend suggests a potential disconnect between Road Traffic Injuries (RTI) research and the mitigation measures put in place. Method: Here, we present an in-depth bibliometric analysis to obtain a comprehensive understanding of RTI research in the GCC region. The Web of Science database was used to search and retrieve the relevant articles during the period of 1981-2019. Results: The volume of RTI research increased from 2015-2019, suggesting an increased focus on traffic safety in the GCC region. Saudi Arabia had the highest RTI research productivity level (126 publications); Bahrain had the lowest (7 publications). Inconsistent with its low publication volume, Hammad Medical Corps of Qatar had the highest citation impact score of 16.33. Global collaboration for RTI research was highest between Saudi Arabia and the United States. The most prevalent publication journal for the region was Accident Analysis and Prevention. The most common keywords were " road traffic accidents" and " road traffic injuries"; terms such as " mobile phones", " pedestrian safety", " pedestrians", and " distracted driving" were least common. In the five most productive GCC nations with respect to RTI research (Saudi Arabia, United Arab Emirates, Qatar, Kuwait, and Oman), researchers tended to publish works related to road traffic safety in traffic safety-oriented journals. Conclusions: The quantity and quality of RTI publications in GCC is insufficient to meet the increasing related public health and economic burden in the region. The trends among publication volumes, citations, and impact were inconsistent. There is a lack of research collaboration among the institutions. Most of the research related to RTI is being conducted by researchers with a medical background. Research focusing on pedestrians, cyclists and road user behavior is also inadequate.

      Introduction: The COVID-19 pandemic is rapidly evolving with the number of cases exponentially rising. The research scientific community has reacted promptly as evidenced by an outstanding number of COVID-19 related publications. As the number of scientific publications rapidly rises, there is a need to dissect the factors that lead to highly impactful publications. To that end, the present paper summarizes the characteristics of the top 50 cited COVID-19-related publications that emerged early during the pandemic.Methods: A systematic search of the Web of Science, Scopus, and Google Scholar was performed, using keywords related to COVID-19 and SARS-CoV-19. Two independent authors reviewed all the search results, screening for the top 50 cited COVID-19-related articles. Inclusion criteria comprised any publication on COVID-19 or the SARS-CoV-2 virus. Data extracted included the type of study, journal, number of citations, number of authors, country of publication, and study content.
    Results: As of May 29th, the top 50 cited articles were cited 63849 times during the last 4 months. On average, 14 authors contributed to each publication. Over half of the identified articles were published in only 3 journals. Furthermore, 42% and 26% of the identified articles were retrospective case series and correspondence/viewpoints, respectively, while only 1 article was a randomized controlled trial. In terms of content, almost half (48%) of the identified publications reported clinical/radiological findings while only 7 out of the 50 articles investigated potential treatments.
    Conclusion: By highlighting the characteristics of the top 50 cited COVID-19-related articles, the authors hope to disseminate information that could assist researchers to identify the important topics, study characteristics, and gaps in the literature.

      Elsevier's Scopus and Scimago Journal & Country Rank (SJR) are reporting inaccurate publication and citation metrics for the Journal of Orthopaedic & Sports Physical Therapy (JOSPT), particularly for the years 2018 and 2019. Despite repeated requests, Elsevier has failed to correct or explain this error to those who use these services, which misrepresents the JOSPT as having a lower impact in the field of musculoskeletal research and rehabilitation. For an accurate representation of the impact of the JOSPT in these fields, authors and readers should rely on the current Web of Science Journal Citation Reports (JCR) and Journal Impact Factor (JIF), which report the Journal's current impact factor to be 3.839 and its 5-year impact factor to be 4.053.

      We aimed to quantify the number of pre- and post-retraction citations obtained by genetics articles retracted due to research misconduct. All retraction notices available in the Retraction Watch database for genetics articles published in 1970-2016 were assessed. The reasons for retraction were fabrication/falsification and plagiarism. The endpoints were the number of citations of retracted articles and when and how journals reported on retractions and whether this was published on PubMed. Four hundred and sixty retracted genetics articles were cited 34,487 times; 7,945 (23%) were post-retraction citations. Median time to retraction and time to last citation were 3.2 and 3 years, respectively. Most (96%) had a PubMed retraction notice, One percent of these were totally removed from journal websites altogether, and 4% had no information available on either the online or PDF versions. Ninety percent of citations were from articles retracted due to falsification/fabrication. The percentage of post-retraction citations was significantly higher in the case of plagiarism (42%) than in the case of fabrication/falsification (21.5%) (p<0.001). Median time to retraction was shorter (1.3 years) in the case of plagiarism than for fabrication/falsification (4.8 years, p<0.001). The retraction was more frequently reported in the PDFs (70%) for the fabrication/falsification cases than for the plagiarism cases (43%, p<0.001). The highest rate of retracted papers due to falsification/fabrication was among authors in the USA, and the highest rate for plagiarism was in China. Although most retractions were appropriately handled by journals, the gravest issue was that median time to retraction for articles retracted for falsification/fabrication was nearly 5 years, earning close to 6800 post-retraction citations. Journals should implement processes to speed-up the retraction process that will help to minimize post-retraction citations.

      Objective: The rise of zoonotic diseases has become a global health issue around the world. The present study is aimed at assessing the global status and the trends in scrub typhus (ST) research.Methods: Publications related to ST studies from 1945 to 21st July 2020 were retrieved from the Scopus database. The search for the ST literature was conducted using the entry terms of the MeSH (Medical Subject Headings) database. Full research articles and reviews were included in the analysis, and no limitation to the language was specified. Key bibliometric indicator analysis was performed using Microsoft Excel, Bibliometrix (an R package), GraphPad Prism 5, and VOSviewer (version 1.6.6).
    Results: A total of 1567 publications were retrieved. The results revealed a significant increase in the number of ST publications over time. The documents received an average of 11.22 citations per document. Mahidol University in Thailand (258, 16.46%) was the most productive institution, while the American Journal of Tropical Medicine and Hygiene published the most ST articles (88, 5.62%). Korea (195, 12.44%) was the most productive country, followed by India (178, 11.36%) and China (106, 6.76%). Richards AL was the most productive author with 36 articles.
    Conclusions: The study findings provide useful insights into the global efforts and works related to the progress of ST research, which can be used to identify future research areas, such as vaccine development.

      OBJECTIVE: The aim of the study was to investigate the global research levels in chronic pancreatitis (CP) fields.METHODS: The term "chronic pancreatitis" was used to retrieve articles published between 2009 and 2018 from the Web of Science database. The 15 highest-output countries' gross domestic product was retrieved to analyze the correlation between output and economic development. The 5 top-ranking countries were compared in quantity and quality. The frequently used terms of all articles were retrieved to conduct co-occurrence analysis to reveal research highlights for CP.
    RESULTS: There were 6094 articles included and 6007 articles were from 15 highest-output countries. There was a positive correlation between output and gross domestic product (r = 0.928, P < 0.001). The United States, China, and Japan had increasing trends in total output (P = 0.022, P < 0.001, and P = 0.021, respectively). China and Japan had increasing trends in output per capita (P < 0.001 and P = 0.023). However, in average impact factor, all 5 countries did not show increasing trends (all P > 0.05). For research highlights, mass lesion and autoimmune pancreatitis were the notable aspects.
    CONCLUSIONS: The global output for CP will continue increasing and research quality will be stable.

      OBJECTIVES: The Coronavirus Disease 2019 (COVID-19) caused heavy burdens and brought tremendous challenges to global public health. This study aimed to investigate collaboration relationships, research topics, and research trends on COVID-19 using scientific literature.METHOD: COVID-19-related articles published from January 1 to July 1, 2020 were retrieved from PubMed database. A total of 27,370 articles were included. Excel 2010, Medical Text Indexer (MTI), VOSviewer, and D3.js were used to summarize bibliometric features.
    RESULTS: The number of the COVID-19 research publications has been continuously increasing after its break. United States was the most productive and active country for COVID-19 research, with the largest number of publications and collaboration relationships. Huazhong University of Science and Technology from China was the most productive institute on the number of publications, and University of Toronto from Canada ranked as Top 1 institute for global research collaboration. Four key research topics were identified, of which the topic of epidemiology and public health interventions has gathered highest attentions. Topic of virus infection and immunity has been more focused during the early stage of COVID-19 outbreak compared with later stage. The topic popularity of clinical symptoms and diagnosis has been steady.
    CONCLUSIONS: Our topic analysis results revealed that the study of drug treatment was insufficient. To achieve critical breakthroughs of this research area, more interdisciplinary, multi-institutional, and global research collaborations are needed.

      Introduction: The volume and quality of biomedical research publications from an institution are considered adequate indicators of the quality of medical care in that institute. King Abdulaziz Medical City (KAMC), Riyadh, Kingdom of Saudi Arabia (KSA), is one of the oldest and most distinguished medical centers in the country.Methods: In this study, we analyzed the number of publications from the Critical Care Unit of the hospital in the past two decades, from 1996 to 2016. The research publications were evaluated on various parameters. Moreover, the impact of their study on global medicine was determined.
    Results: Our results indicate a steady progression in the number of publications from the institute in the past two decades. An average of 17.3 papers was published each year during this time. Out of the 283 publications from KAMC included in this study, the majority of the publications were original articles, 61 were review articles, 66 were multicenter trial studies and 28 were randomized control trials. The citation profile of the publications was good indicating global impact of the studies.
    Conclusion: The global impact of research as evaluated through published manuscripts in KAMC is overall good. This was deduced from both the increase in the number of publications each year and also the quality of papers as evidenced by the citation index of the papers published between 1996 and 2016.

      Despite the rapid growth of the global health field over the past few decades, consensus on what qualifies as global health scholarship or practice remains elusive. We conducted a meta-knowledge analysis of the titles and abstracts of articles published in 25 journals labelled as global health journals between 2001 and 2019. We identified the major topics in these journals by creating clusters based on terms co-occurrence over time. We also conducted a review of global health definitions during the same period.The analysis included 16 413 articles. The number of journals, labelled as global health, and articles published in these journals, increased dramatically during the study period. The majority of global health publications focused on topics prevalent in low-resource settings. Governance, infectious diseases, and maternal and child health were major topics throughout the analysis period. Surveillance and disease outcomes appeared during the 2006-2010 epoch and continued, with increasing complexity, until the 2016-2019 epoch. Malaria, sexual and reproductive health, and research methodology appeared for only one epoch as major topics. We included 11 relevant definitions in this analysis. Definitions of global health were not aligned with the major topics identified in the analysis of articles published in global health journals.These results highlight a lack of alignment between what is published as global health scholarship and global health definitions, which often advocate taking a global perspective to population health. Our analysis suggests that global health has not truly moved beyond its predecessor, international health. There is a need to define the parameters of the discipline and investigate the disconnect between what is published in global health versus how the field is defined.

      There has been an increase of fertility desire among people living with HIV/AIDS (PLWH) thanks to the advancement of HIV treatment and prevention of mother-to-children transmission programs. However, the development of research focusing on this topic over the past three decades is not well documented. We aimed to explore the trend of global publications regarding fertility desires among PLWH and identify their contents through the natural language processing technique. Dataset from 1992 to 2019 was downloaded using the Web of Science Core Collection. Bibliometric indicators such as change in total publications, citations, and countries' collaboration were examined. Main topics of selected publications were determined using the latent Dirichlet allocation. There were 303 articles published during the period 1992-2019, with a rapid increase in the number of publications in the past 5 years. Common themes included determinants of fertility desire, HIV prevention for adolescents, and safer conception for couples affected with HIV. However, publications on HIV care and antenatal care for women with HIV had been still limited. Findings suggested a call for the future support and collaborations for fertility intention, as well as the promotion of HIV care and service for adolescents and pregnant women with HIV, especially in countries with poor resources and a high burden of HIV/AIDS.

      The objective of this analysis was to explore the research hotspot of coronavirus disease 2019 (COVID-19) mechanical ventilation. The literature related to COVID-19 mechanical ventilation on PubMed and CNKI database of core journals was retrieved with the keyword of COVID-19 mechanical ventilation. The visualisation software of VOS (visualisation of similarities) viewer performed by the authors and high-frequency keywords. A total of 524 English language articles from PubMed and 81 Chinese literature from China National Knowledge Infrastructure (CNKI) of core journals are included in this paper. The two databases produced six research fields, among which much attention was paid to the prevention of nosocomial infection and antiviral agents in the treatment of mechanical ventilation. The literature yeilded by PubMed paid attention to the factors affecting the poor prognosis of mechanically ventilated patients, the management and research and development of medical data during COVID-19's pandemic, the mechanical ventilation treatment of COVID-19 pregnant women, the mechanical ventilation treatment and nursing in the field of CNKI literature research, and the nutritional treatment of severe pneumonia patients with mechanical ventilation. The current COVID-19 researches, focused on the prevention of nosocomial infection and antiviral drugs in the process of mechanical ventilation, are a new hotspot in the world. Key Words: Coronavirus disease 2019 (COVID-19), Mechanical ventilation, Research hotspot, VOSviewer, Visual analysis.

      Research productivity is a vital component to an academic neurosurgeon's career. We sought to evaluate gender differences in NIH funding among faculty in neurological surgery departments. NIH funding awarded to PIs of neurological surgery departments from 2014 to 2019 were obtained and analyzed for gender differences in funding trends, with attention to terminal degree and academic rank, as well as publication range in length of years and h-index. 79.4% of all NIH grants were awarded to male PIs, with the remaining 20.5% given to their female counterparts. Mean of the total NIH grants awarded to men was significantly higher at $1,796,684 (± Standard Error of Mean (SEM) $155,849, IQR: $1,759,250) compared to women at $1,151,968 (± SEM $137,914, IQR: $1,388,538) (P = 0.022). Mean NIH funding per grant for men was $365,760 (± SEM: $39,592, IQR: $189,692) and for women was $292,912 (± SEM: 28,239, IQR: $283,177). Differences in mean NIH funding per grant approached but did not reach statistical significance between men and women (P = 0.122). When stratified for academic rank, there was a significant difference in mean NIH funding per grant between men and women on the associate professor level (p < 0.005), with women exceeding men in funding at this academic level, with other academic ranks remaining non-significant. Overall, male neurosurgeons receive significantly more total NIH grant funding than their female counterparts, except at the level of associate professor where women were found to surpass men.

      INTRODUCTION: Physicians, whether in the public or private sector, are increasingly bound to "publish or perish". Although researchers have become aware of certain ethical concerns relating to the concept of authorship, clinicians still tend to neglect issues of copyright. The present study aims: 1) to explain to orthopedic surgeons what exactly is protected by copyright in a scientific article; 2) to assess the legal implications of publishing contracts; and 3) to specify the means of publication that best boost the author's h-index.MATERIAL AND METHODS: The study was based on intellectual property legislation and jurisprudence and the underlying principles. The European and American medical and legal literature was analyzed.
    RESULTS: It is vital to understand the basic principles of copyright and the legal implications of publishing contracts. A scientific article is protected by copyright as soon as it has been written. This confers both moral and property rights. "Moral" rights protect the person of the author and are inalienable; unlike property rights, they cannot be transferred. Publishing contracts can only concern property and other derivative rights. Most scientific articles are published in open access via Creative Commons (CC) licenses. The greater the freedom of use provided for in the CC license, the more easily other authors can use the article, adding to it or altering it. As all CC licenses include an attribution clause, authors publishing under a relatively unrestrictive CC license increase the chances of boosting their h-index.
    CONCLUSION: Forewarned is forearmed. Mastering the means of publication enables authors to make the most of their publications in boosting their h-index, and also to contribute to the new Open Science paradigm: abandoning some intellectual property in favor of innovation and knowledge sharing rather than clinging to data protection.

      Writing scientific articles is immensely rewarding but challenging. This Perspective provides the medicinal chemist with background and advice on the art and process of writing manuscripts and complements the instructions to authors provided by journals. Included are many tips that we wish we had known when we first started writing. Bibliometric data from seven medicinal chemistry journals between 2000 and 2019 are collated including Bioorganic and Medicinal Chemistry Letters and the Journal of Medicinal Chemistry. Although the overall number of articles has doubled, the output from 23 large pharma companies in the past decade has dropped significantly. Commentary is given on the entire process of writing original scientific articles, opinion articles, and reviews. Examples from our own papers and experience are shared including what typically motivates the writer, challenges commonly encountered, and how we find time to write. Finally, the benefits derived from much wider publishing of industrial medicinal chemistry are described.

      Selective publication and reporting in individual papers compromise the scientific record, but are meta-analyses as compromised as their constituent studies? We systematically sampled 63 meta-analyses each comprising least 40 studies in PLOS One, top medical journals, top psychology journals, and Metalab, an online, open-data database of developmental psychology meta-analyses. We empirically estimated publication bias in each, including only the peerreviewed studies in each. Across all meta-analyses, we estimated that "statistically significant" results in the expected direction were only 1:17 times more likely to be published than "nonsignificant" results or those in the unexpected direction (95% CI: [0:93, 1:47]), with a confidence interval substantially overlapping the null. Comparable estimates were 0.83 for meta-analyses in PLOS One, 1.02 for top medical journals, 1.54 for top psychology journals, and 4.70 for Metalab. The severity of publication bias did differ across individual meta-analyses; in a small minority (10%; 95% CI: [2%, 21%]), publication bias appeared to favor "significant" results in the expected direction by more than 3-fold. We estimated that for 89% of meta-analyses, the amount of publication bias that would be required to attenuate the point estimate to the null exceeded the amount of publication bias estimated to be actually present in the vast majority of meta-analyses from the relevant scientific discipline (exceeding the 95th percentile of publication bias). Study-level measures ("statistical significance" with a point estimate in the expected direction and point estimate size) did not indicate more publication bias in higher-tier versus lower-tier journals, nor in the earliest studies published on a topic versus later studies. Overall, the mere act of performing a meta-analysis with a large number of studies (at least 40) and that includes non-headline results may largely mitigate publication bias in meta-analyses, suggesting optimism about the validity of meta-analytic results.

      The issue of multirisk is coming under increasing scrutiny in the scientific literature and is of great concern for governments. Multirisk embraces different meanings: domino and cascade effects, NaTech events and the consideration of several natural hazards and their interactions. Scientific production relating to multirisk has been growing over the last 15 years. This review, based on 191 articles, proposes a new way of analyzing and presenting bibliographic results by the use of a global textual analysis. This analysis leads to identify seven main themes of research in the literature: three concern Domino Effects (46.6% of the articles), two are dedicated to the assessment of Multi-(hazard/vulnerability) Risk (28.7%), one deals with Natech issues (13.5%) and one concerns Cascade Effects in critical infrastructures (11.2%). A cross-issue analysis was performed on the basis of four criteria: objectives, hazards, the elements at risk considered, and the approaches used or developed in the articles. It provides general lessons on these items and proposes themes for future research on the topic of multirisk.
