      Malware is a blanket term for Trojan, viruses, spyware, worms, and other files that are purposely created to harm computers, mobile devices, or computer networks. Malware commonly steals, encrypts, damages, and causes a mess in these devices. The growth of malware attacks has a consequence on the growth and attractiveness of mobile features in mobile devices. Most malware research aims to probe the different methods of preventing, analysing, and detecting malware attacks. This paper aims to demonstrate an exhaustive knowledge map of the Android malware by collecting a ten (10) year dataset from the Web of Science database. A bibliometric analysis was employed for analysing articles published between 2010 and 2019. Using the keyword "malware", 5622 articles were retrieved. After scrutinising with the keywords of "Android malware", 1278 articles were then collected. This study provides an overview of the articles, productivity, research area, the Web of Science categories, authors, high-cited articles, institutions, and impact journals examining malware. Research activities are continued by placing terms in the classification of malware detection systems that outline important areas in malware research. From the analysis, it can be concluded that the highest number of publications focusing on malware studies came from the continent of Asia. Additionally, this study discusses the challenges of malware studies in the recent research studies as well as the future direction.

      OBJECTIVE: Peripheral artery disease (PAD) is a highly prevalent disease that places major lifestyle limitations and mortality risk on affected individuals. As the understanding of the disease has grown in the medical community, it is unknown which literature has made the greatest impact on the knowledge of peripheral artery disease. We performed a bibliometric analysis using the number of citations as an indication of impact to analyze the top one hundred most influential articles on PAD management.METHODS: A retrospective search of the Web of Science (Thomson Reuters, New York, NY) database for English-only publications was conducted in November 2020. We identified initial references from the database using the search terms "Peripheral Arterial Disease", "Peripheral Vascular Disease", "Claudication", "Critical Limb Ischemia", "Chronic Limb Threatening Ischemia", "Rest Pain", "Ischemic Ulcer", "Toe Gangrene", "Ankle Brachial Index" and "Leg Ischemia" in Web of Science Core Collections. Articles were ranked based on the number of citations and then analyzed based on citation count and average number of citations per year. Additional metrics included the overall average number of publications per year, the journals, journal discipline, author (including degree and gender), institution, country, topic area, and the level of evidence.
    RESULTS: The most popular articles were published between 1959 to 2017, with 46,716 citations in total (average 27.26 citations/year). The most popular article had 2225 citations in total and was Rutherford's "Recommended standards for reports dealing with lower extremity ischemia: Revised version". Peak years of citations were 2016, 2014, and 2018 (2,753, 2,674, and 2,639 citations, respectively). Top journals for the most cited publications were Circulation, Journal of Vascular Surgery, and the Lancet with 21, 13, and 7 articles respectively. A majority of articles originated from the United States (58 articles), followed by the United Kingdom (15 articles) and Germany (13 articles). Major topic areas of interest and trends in the progressive understanding of PAD were noted. Top areas of focus included surgical interventions (29%), therapeutic angiogenesis (15%), epidemiological studies in PAD (14%), and diagnosis and evaluation (13%). In the top cited literature, 48% (14/29) of surgical articles investigated endovascular interventions for peripheral artery disease.
    CONCLUSIONS: Overall, PAD research has evolved from basic epidemiological studies to advanced management with continued investigation towards future, improved treatments for PAD.

      Bibliometric indicators have been devised to quantify scientific production and to try to evaluate its impact in the community. In general, bibliometric indicators can be classified according to whether the unit of analysis is the author (individual or group) or journal. The most widely used indicators for authors are those that measure an individual author's production, such as the Crown index or the h-index and its derivatives (e-index, h5-index, and the absolute or Ab-index, among others). The bibliometric indicators devised to try to evaluate journal quality are associated with Journal Citation Reports (e.g., impact factor, field-weighted citation impact, Eigenfactor, and article influence) or with Scopus (Scimago Journal Rank (SJR), source normalized impact per paper (SNIP), and CiteScore). This article describes the main bibliometric indicators, explains how they are calculated, and discusses their advantages and limitations.

      ABSTRACT: Craniofacial surgery continues to be a rapidly evolving field, due in part to interdisciplinary collaboration that has allowed for sharing of knowledge and methodologies, which has expanded greatly due to online journals and publications. The Journal of Craniofacial Surgery (JCS) is a highly regarded journal that has attracted attention for its mission to increase diversity and global representation in manuscript submissions and research publications. The purpose of this study is to provide an objective measurement of global participation in craniofacial research specifically as it pertains to the JCS. Through a bibliometric analysis, the country of origin of all articles published in the JCS from 2010 to 2019 was analyzed. In line with its mission, the JCS increased its overall production 1.9 times during the past decade and increased its global representation 1.6 times, as represented by the number of countries contributing (78). The journal produced 8147 articles with Turkey (1424), USA (1397), China (1178), South Korea (1023), and Italy (644) being the top producers. The highest represented states were Florida (156), New York (130), California (117), Massachusetts (112), and Pennsylvania (106). The Journal of Craniofacial Surgery has the greatest diversity of country representation of the major plastic and reconstructive journals compared. Overall the JCS has stayed true to its mission to foster craniofacial research and is a valuable resource for craniofacial surgeons across the world. This study provides an analysis of trends in global contributions to craniofacial research and highlights areas for further increasing global contributors to the field of craniofacial surgery.
  5. Arthroplast Today. 2021 Feb;7 225-229
      Background: Citation analysis is commonly used to evaluate the impact of academic publications within an area of study. The purpose of this study is to review the publications with the highest Altmetric scores related to total hip arthroplasty (THA) and total knee arthroplasty (TKA) and assess the correlation with traditional bibliometrics.Methods: Altmetric scores were obtained for the top articles relating to THA and TKA and organized from highest to lowest scores. The Clarivate Analytics Web of Knowledge database was used to search the top articles by Altmetric score. Articles meeting inclusion criteria were reviewed for various metrics, including number of citations, journal impact factor at the time of publication, and study type and design.
    Results: The top THA and TKA publications were cited 3042 times and 7523 times, respectively. The former were published in journals with an average impact factor of 17.861, and the latter in journals with an average impact factor of 15.564. For THA, Altmetric score demonstrated a significant, weakly positive correlation with the number of citations (P = .008). For TKA, Altmetric score was found to have a significant, weakly positive correlation with impact factor of journal (P = .04); however, it was nonsignificant for citation count (P = .11). When one outlier is removed, the correlation with citation count is statistically significant (P = .009).
    Conclusion: While alternative metrics cannot replace traditional bibliometrics, they may serve a complimentary role in describing the influence of research. Thus, the Altmetric score represents an additional tool to identify the most influential articles to guide learning and evidence-based practice.

      BACKGROUND: The objective of the present review is to perform the 1st bibliometric analysis of sleep disorders research.METHODS: The data was retrieved from Scopus in July, 2020 for detail analysis.
    RESULTS: The 1st precise document about the sleep disorder was published in 1945. Till 15th July 2020, total 69657 documents were found in Scopus database. Approximately eighty two percent (57013/81.87%) documents are published in the last twenty years (from 2001-2020). We calculated the per year growth rate (GR) of publications (from 2000-onwards). The highest number of documents are published in 2019 (4337/7.90% of 57013) followed by 2018 (4249/7.74% of 57013) and 2017 (3974/7.24% of 57013). Infact the productivity index (PI) for 1950-1960 and 2011-2020 era was found to be 100.21. We also provided the details of the top 50 countries with maximum number of publications (from 1945 to July 2020). The top three (3) countries are USA with 24262 publications (34.83%), followed by UK (5566/8.0%) and Germany (4791/6.87%). We also performed the co-words analysis. Infact total 956643 (0.95 million) keywords were retrieved from 69657 published documents. After critical analysis we categorized them in different groups to show the trend in various domains. In the next phase of the study, only those documents were analyzed which contained the phrase "sleep disorder" in the titles of the publications. Total 3626 documents were found. We calculated the per year growth rate (GR). The continental distribution, the list of top twenty authors, sources/journals, departments or institutes, countries and research documents with highest citations are provided. By VOSviewer analysis, 6752, 36511 and 11473 terms in titles of the manuscripts, abstracts and keywords were recorded, respectively. This may help in describing the overall trend in these publications.
    CONCLUSIONS: The present study provides a detail list of top authors, departments, countries, sources and top 20 most cited documents. The co-words analysis may help in describing the trends in the field of sleep disorders.

      Background The purpose of this study is to evaluate and compare publishing characteristics in foot and ankle trauma articles published in two subspecialty journals and two general orthopedic journals. Methods All trauma articles related to foot and ankle surgery published from five different time intervals over a 20-year period were collected and the following was analyzed: authorship, level of evidence, type of study, citations, and geographic region. Results Foot and Ankle International (FAI) had the highest percentage of last and corresponding authors that were fellowship-trained in foot and ankle. The Journal of Bone and Joint Surgery American and British volumes (JBJS(A) and JBJS(B), respectively) and the Journal of Orthopaedic Trauma (JOT) articles had a higher percentage of last and corresponding authors that were fellowship-trained in trauma. Conclusion Foot and ankle-trained authors are currently under-represented in foot and ankle trauma literature. As the field of foot and ankle continues to grow, it is important that the experts in the field are well represented in the literature.

      Buildings account for nearly 2/5ths of global energy expenditure. Due to this figure, the 90s witnessed the rise of green buildings (GBs) that were designed with the purpose of lowering the demand for energy, water, and materials resources while enhancing environmental protection efforts and human well-being over time. This paper examines recent studies and technologies related to the design, construction, and overall operation of GBs and determines potential future research directions in this area of study. This global review of green building development in the last two decades is conducted through bibliometric analysis on the Web of Science, via the Science Citation Index and Social Sciences Citation Index databases. Publication performance, countries' characteristics, and identification of key areas of green building development and popular technologies were conducted via social network analysis, big data method, and S-curve predictions. A total of 5246 articles were evaluated on the basis of subject categories, journals' performance, general publication outputs, and other publication characteristics. Further analysis was made on dominant issues through keyword co-occurrence, green building technologies by patent analysis, and S-curve predictions. The USA, China, and the UK are ranked the top three countries where the majority of publications come from. Australia and China had the closest relationship in the global network cooperation. Global trends of the top 5 countries showed different country characteristics. China had a steady and consistent growth in green building publications each year. The total publications on different cities had a high correlation with cities' GDP by Baidu Search Index. Also, barriers and contradictions such as cost, occupant comfort, and energy consumption were discussed in developed and developing countries. Green buildings, sustainability, and energy efficiency were the top three hotspots identified through the whole research period by the cluster analysis. Additionally, green building energy technologies, including building structures, materials, and energy systems, were the most prevalent technologies of interest determined by the Derwent Innovations Index prediction analysis. This review reveals hotspots and emerging trends in green building research and development and suggests routes for future research. Bibliometric analysis, combined with other useful tools, can quantitatively measure research activities from the past and present, thus bridging the historical gap and predicting the future of green building development.

      For the foreseeable future, industrial water demand will grow much faster than agriculture. The demand together with the urgency of wastewater treatment, will pose big challenges for most developing countries. We applied the bibliometric analysis combined with social network analysis and S-curve technique to quantitatively analyze 9413 publications related to industrial wastewater treatment in the Scientific Citation Index (SCI) and Social Sciences Citation Index (SSCI) databases from 1998 to 2019. The results showed that: (1) Publications on industrial wastewater treatment have increased from 120 in 1998 to 895 in 2019 with a steady annual increment rate, and researchers have focused more on the application and optimization of existing technologies. (2) China had the highest number of publications (n = 1651, 19.66% of global output) and was a core country in the international cooperation network, whereas the United States and European countries produced higher quality papers. (3) By analyzing the co-occurrence and clusters of keywords and comparing three wastewater treatment categories (physical, chemical, biological), adsorption (n = 1277), oxidation (n = 1085) and activated sludge process (n = 1288) were the top three techniques. Researchers have shifted their focus to treatment technologies for specific wastewater type, such as textile wastewater, pulp and paper wastewater, and pharmaceutical wastewater. The S-curve from articles indicates that physical and chemical treatment technologies are attached with great potential in the near future, especially adsorption and advanced oxidation, while the biological treatment technologies are approaching to the saturation stage. Different pattern is observed for the S-curve derived from patents, which stressed the limited achievement until now and further exploration in the field application for the three treatment categories. Our analysis provides information of technology development landscape and future opportunities, which is useful for decision makers and researchers who are interested in this area.

      Citations are an important, but often overlooked, part of every scientific paper. They allow the reader to trace the flow of evidence, serving as a gateway to relevant literature. Most scientists are aware of citations errors, but few appreciate the prevalence of these problems. The purpose of this study was to examine how often frequently cited papers in biomedical scientific literature are cited inaccurately. The study included an active participation of first authors of included papers; to first-hand verify the citations accuracy. Findings from feasibility study, where we reviewed 1,540 articles containing 2,526 citations of 14 most cited articles in which the authors were affiliated with the Faculty of Medicine University of Belgrade, were further evaluated for external confirmation in an independent verification set of articles. Verification set included 4,912 citations identified in 2,995 articles that cited 13 most cited articles published by authors affiliated with the Mayo Clinic Division of Nephrology and Hypertension. A citation was defined as being accurate if the cited article supported or was in accordance with the statement by citing authors. At least one inaccurate citation was found in 11% and 15% of articles in the feasibility study and verification set, respectively, suggesting that inaccurate citations are common in biomedical literature. The most common problem was the citation of nonexistent findings (38.4%), followed by an incorrect interpretation of findings (15.4%). One fifth of inaccurate citations were due to chains of inaccurate citations. Based on these findings, several actions to reduce citation inaccuracies have been proposed.

      Background: Cognitive behavioural therapy (CBT) is considered to be an effective treatment for schizophrenia. In recent years, researchers have published clinical research results on CBT for schizophrenia. However, there is currently a lack of bibliometric analysis on CBT for schizophrenia.Aims: To understand the current situation and research trends of CBT for schizophrenia, and to provide valuable information for researchers in this field.
    Methods: Literature was retrieved from the Web of Science Core Collection database. CiteSpace was used to visually analyse the current status of research on CBT for schizophrenia, as well as trends and points of general interest on this topic.
    Results: A total of 1151 papers were retrieved. The annual number of publications has increased 417.65% from 2000 to 2019. Schizophrenia Research was the most active journal. McGorry enjoys considerable influence. The University of London is deemed to be the most active research institution. England and the USA retain the highest scientific productivity in this field. China and Norway might make more contributions to this field in the future. The most important research topics are randomised controlled trials of CBT for schizophrenia, meta-analysis, scale selection and research on the improvement of quality of life. Results from the following keywords 'psychoeducation', 'insomnia', 'individual', 'mental illness', 'major depressive disorder', 'efficacy', 'internalised stigma' and 'remediation' indicated new research frontiers in this field.
    Conclusions: The field of CBT for schizophrenia is progressing and has great potential. The level and quality of research in this field is high. The proposal of research hotspots and frontiers serves as a direction for researchers in this field. Researchers around the world should strengthen their cooperation and communication to promote further development of this field.

      BACKGROUND: Shortly after the emergence of the novel coronavirus disease (COVID-19), researchers rapidly mobilized to study numerous aspects of the disease such as its evolution, clinical manifestations, effects, treatments, and vaccination. This led to a rapid increase in the number of COVID-19-related publications. Identifying trends and areas of interest using traditional review methods (e.g., scoping review and systematic reviews) for such a large domain area is challenging.OBJECTIVE: We aimed to conduct an extensive bibliometric analysis to provide a comprehensive overview of the COVID-19 literature.
    METHODS: We used the COVID-19 Open Research Dataset (CORD-19) that consists of large number of articles related to all coronaviruses. We used machine learning method to analyze most relevant COVID-19 related articles and extracted most prominent topics. Specifically, we used clustering algorithm to group articles based on similarity of their abstracts to identify the research hotspots and current research directions. We have made our software accessible to the community via GitHub.
    RESULTS: Of the 196,630 publications retrieved from the database, we included 28,904 in the analysis. The mean number of weekly publications was 990 (SD=789.3). The country that published the highest number of articles was China (n=2,950). The largest number of documents was published in BioRxiv. Lei Liu affiliated in the Southern University of Science and Technology in China published the highest number of documents (n=46). Based on titles and abstracts alone, we were able to identify 1,515 surveys, 733 systematic reviews, 512 cohort studies, 480 meta-analyses, 362 randomized control trials. We identified 19 different topics addressed by the included studies. The most dominant topic was public health response followed by clinical care practices during COVID-19, its clinical characteristics and risk factors, and epidemic models for its spread.
    CONCLUSIONS: We provided an overview of the COVID-19 literature and identified current hotspots and research directions. Our findings can be useful for the research community to help prioritize research needs, and recognize leading COVID-19 researchers, institutes, countries, and publishers. This study showed that an AI-based bibliometric analysis has the potential to rapidly explore large corpora of academic publications during a public health crisis. We believe that this work can be used to analyze other eHealth related literature to help clinicians, administrators and policy makers to have a holistic view of the literature and be able to categorize the different topics of existing research for further analysis. It can be further scaled, for instance in time, to clinical summary documentation. Publishers should avoid noise in the data by developing a way to trace the evolution of individual publications and unique authors.

      We present norms for faculty citation counts based on 811 faculty members at 30 PhD-granting psychology departments in the United States across the range of the National Research Council rankings. The metrics were highly skewed, with most scientists having a low to moderate number of citations of their work and a few scientists having extremely high numbers. However, the median per-year citation count was 149, showing widespread scientific contributions across scholars. Some individuals in lower ranked departments are more highly cited than the average scholar in higher ranked departments, with enormous variation in citation counts in both the low- and high-ranking departments. Citation counts overall have risen in recent years, and the citations of early-career scholars are increasing at a faster rate than their senior colleagues did at the same point in their careers. We found that citation counts at the beginning of scientists' careers substantially predict lifetime citation success. Young scholars' citation counts are associated with obtaining positions at higher ranked universities. Finally, we found no significant differences for subfields of psychology. In sum, although a few highly productive scientists have a very large influence, trends reveal that contributions to psychological science are growing over time, widespread, and not limited to a few stars and elite departments.

      Background The development of statistical software in research has transformed the way scientists and researchers conduct their statistical analysis. Despite these advancements, it was not clear which statistical software is mainly used for which research design thereby creating confusion and uncertainty in choosing the right statistical tools. Therefore, this study aimed to review the trend of statistical software usage and their associated study designs in articles published in health sciences research. Methods This bibliometric analysis study reviewed 10,596 articles published in PubMed in three 10-year intervals (1997, 2007, and 2017). The data were collected through Google sheet and were analyzed using SPSS software. This study described the trend and usage of currently available statistical tools and the different study designs that are associated with them. Results Of the statistical software mentioned in the retrieved articles, SPSS was the most common statistical tool used (52.1%) in the three-time periods followed by SAS (12.9%) and Stata (12.6%). WinBugs was the least used statistical software with only 40(0.6%) of the total articles. SPSS was mostly associated with observational (61.1%) and experimental (65.3%) study designs. On the other hand, Review Manager (43.7%) and Stata (38.3%) were the most statistical software associated with systematic reviews and meta-analyses. Conclusion In this study, SPSS was found to be the most widely used statistical software in the selected study periods. Observational studies were the most common health science research design. SPSS was associated with observational and experimental studies while Review Manager and Stata were mostly used for systematic reviews and meta-analysis.

      This study proposes a bibliometric measure to visualize and analyze the research status and development trend of carbon offset based on 1,581 articles over the period 1900-2019. The main findings include (1) carbon offset research turned into a rapid growth after 2009; (2) environmental studies, environmental science, economics, and energy fuels are the top four research domains in publication; (3) Energy Policy, Ecological Economics and Science are the top three journals in terms of citation impact; (4) climate change, impact, emission, CO2 emission, and policy are shown to be the most frequently used keywords; (5) the top 10 cited articles cover the following five essential aspects: individual carbon offset behavior; forest and land carbon offset; transportation carbon offset; international trade carbon offset; and eco-system service-related carbon offset; (6) eight research hotspots were identified including forest carbon sequestration program, understanding carbon and uncertainty market, policy design, biomass development, Chinese province, increasing adoption, and ecosystem service commodification. These findings suggest that the carbon offset research has been evolved from the theoretical exploration at the early stage to a more diversified conversion of research outputs at the practical level in recent years. Interdisciplinary research towards individual and organizational carbon offset behaviors in a broader context of socio-economic development and cooperation among various agents is the emphasis and direction for future study.

      BACKGROUND: To evaluate the frequency and reason for retraction of ophthalmology publications.METHODS: Two independent reviewers retrieved data from PubMed and Medline using appropriate keywords. Statistical analysis was carried out using Mann-Whitney U test. A total of 83 articles were selected for the analysis between 1994 and 2019. Articles were retracted after a median of 1 year (IQR 4.0), and 55 (66.3%) articles were published in the year 2010 or after.
    RESULTS: Forty-eight (57.8%) articles were original articles. The most common subspecialties involved were basic science (51.8%), followed by vitreoretinal diseases (13.3%) and cornea and external diseases (7.1%). Fraudulent data were the cause of retraction in 22 (26.5%) articles, and 14 articles (16.87%) were retracted because of plagiarism. Thirteen articles (15.7%) were retracted due to errors in the data calculations, and ten (12.04%) were found to be duplicate submissions of previously published articles by the same author, while five articles (6.02%) had authorship disputes. Thirty-nine (46.9%) retracted articles were published in a journal with an impact factor greater than 2. The median number of citations received by the retracted articles was 2.0 (IQR 9.0).
    CONCLUSIONS: We conclude that the number of retractions in the ophthalmic literature have increased since 2010, though relatively limited information is available on the retracted articles. There is a need to strictly follow the current guidelines for providing the reasons for retraction and displaying retraction notices both in PubMed and on the journal websites.

      Predatory publishing represents a major challenge to scholarly communication. This paper maps the infiltration of journals suspected of predatory practices into the citation database Scopus and examines cross-country differences in the propensity of scholars to publish in such journals. Using the names of "potential, possible, or probable" predatory journals and publishers on Beall's lists, we derived the ISSNs of 3,293 journals from Ulrichsweb and searched Scopus with them. 324 of journals that appear both in Beall's lists and Scopus with 164 thousand articles published over 2015-2017 were identified. Analysis of data for 172 countries in 4 fields of research indicates that there is a remarkable heterogeneity. In the most affected countries, including Kazakhstan and Indonesia, around 17% of articles fall into the predatory category, while some other countries have no predatory articles whatsoever. Countries with large research sectors at the medium level of economic development, especially in Asia and North Africa, tend to be most susceptible to predatory publishing. Arab, oil-rich and/or eastern countries also appear to be particularly vulnerable. Policymakers and stakeholders in these and other developing countries need to pay more attention to the quality of research evaluation.Supplementary information: The online version contains supplementary material available at (10.1007/s11192-020-03852-4).

      Background: Cardiovascular disease (CVD) is the leading cause of death and disability worldwide. Health research is crucial to managing disease burden. Previous work has highlighted marked discrepancies in research output and disease burden between high-income countries (HICs) and low- and lower-middle-income countries (LI-LMICs) and there is little data to understand whether this gap has bridged in recent years. We conducted a global, country level bibliometric analysis of CVD publications with respect to trends in disease burden and county development indicators.Methods: A search filter with a precision and recall of 0.92 and 0.91 respectively was developed to extract cardiovascular publications from the Web of Science (WOS) for the years 2008-2017. Data for disease burden and country development indicators were extracted from the Global Burden of Disease and the World Bank database respectively.
    Results: Our search revealed 847,708 CVD publications for the period 2008-17, with a 43.4% increase over the decade. HICs contributed 81.1% of the global CVD research output and accounted for 8.1% and 8.5% of global CVD DALY losses deaths respectively. LI-LMICs contributed 2.8% of the total output and accounted for 59.5% and 57.1% global CVD DALY losses and death rates.
    Conclusions: A glaring disparity in research output and disease burden persists. While LI-LMICs contribute to the majority of DALYs and mortality from CVD globally, their contribution to research output remains the lowest. These data call on national health budgets and international funding support to allocate funds to strengthen research capacity and translational research to impact CVD burden in LI-LMICs.

      What may seem to be a marginal modification of calculating the impact factor provided by Journal Citation Reports, changes our publishing landscape quite a bit. What is new? Starting with the upcoming 2020 impact factor released this June, early access content will be taken as the initial publishing date. Early access is practiced by many publishers such as Wiley, which publishes Acta Physiologica, where it is referred to as Early View. There are good reasons to start counting citations to an article at this first stage of appearance. In site the call for providing scientific content as early as possible, some journals do not offer early access, which will negatively affect the impact factor of that journal. It takes weeks before a study is digested and cited.

      This paper describes a unique two-step methodology used to construct six linked bibliometric datasets covering the sequencing of Saccharomyces cerevisiae, Homo sapiens, and S us scrofa genomes. First, we retrieved all sequence submission data from the European Nucleotide Archive (ENA), including accession numbers associated with each species. Second, we used these accession numbers to construct queries to retrieve peer-reviewed scientific publications that first linked to these sequence lengths in the scientific literature. For each species, this resulted in two associated datasets: 1) A .csv file documenting the PMID of each article describing new sequences, all paper authors, all institutional affiliations of each author, countries of institution, year of first submission to the ENA, and the year of article publication, and 2) A .csv file documenting all institutions submitting to the ENA, number of nucleotides sequenced, number of submissions per institution in a given year, and years of submission to the database. In several upcoming publications, we utilise these datasets to understand how institutional collaboration shaped sequencing efforts, and to systematically identify important institutions and changes in network structures over time. This paper, therefore, should aid researchers who would like to use these data for future analyses by making the methodology that underpins it transparent. Further, by detailing our methodology, researchers may be able to utilise our approach to construct similar datasets in the future.

      The point of view of the author of this article, who participates in the work of several scientific journals, on the current situation with publishing articles by scientists of various specialties is presented. Two approaches to this problem are considered: "informal" (focused only on the quality of published manuscripts) and "formal" (taking into account mainly the scientometric indicators of both authors and journals). The continuous commercialization of this process, associated with the emergence of a huge number of publications that require significant article processing charges from scientists to publish the results of their research, is noted. At the same time, the financial interests of publishers promote reducing the requirements for reviewing and editing articles submitted to the editorial board. It is emphasized the need for the appropriate formal scientometric indicators for researchers applying for grants as well as for the corresponding positions and titles, which has arisen at the present stage. According to the author, excessive attention to such formal rankings does not improve the effectiveness of scientific publications, negatively affecting, in particular, the process of blind peer reviewing, grammar and style of manuscripts, statistical processing of data given in articles, design of illustrations, as well as the quality of reference lists.

      Objectives: Authorship trends, female authors' contributions, and the collaboration among institutions have been a concern in the medical field. This study primarily aims to report and compare the number of authors per article and the prevalence of female authors by comparing two orthopaedics journals from the Arab world. The secondary objective of this study is to evaluate the characteristics of the authors' affiliations and the pattern in institutions' collaborations and contributions to the published articles.Methods: This cross-sectional study reviewed all articles (until July 2020) published in the Archives of the Egyptian Orthopaedic Journal (EOJ) (the official journal of the Egyptian Orthopaedic Association) and the Journal of Musculoskeletal Surgery and Research (JMSR) (the official journal of the Saudi Orthopaedic Association).
    Results: We evaluated 383 and 122 articles from the EOJ and JMSR, respectively. The average number of authors per article was significantly higher for JMSR (4.3 ± 1.7) than EOJ (2.0 ± 1.0); p = 0.000. There was a significantly larger number of contributions by female authors in JMSR (75, 14.2%) than EOJ (2, 0.3%); p = 0.000. The average number of institutions per article was significantly larger for JMSR (2.1 ± 1.2) than EOJ (1.1 ± 0.3); p = 0.000. For the JMSR, the incidence of national institutions' cooperation (27.9%) and international institutions' contributions (53.3%) were significantly higher than their counterparts for the EOJ-6% and 4.7%, respectively; p = 0.000.
    Conclusion: The JMSR showed superiority regarding the number of authors per article and the prevalence of female authors. The incidence of national institutions' cooperation and international contributions were higher in the JMSR compared with the EOJ.

      Development of medical rehabilitation technologies are the investments into «human capital». The effectiveness criterion of the scientific institutions work dealing with the problems of rehabilitation is the scientific publication activity of their employees in this subject in high-ranking international databases (DB).Purpose of the study. Analysis of the state of the scientific publication flow in the field of rehabilitation.
    MATERIAL AND METHODS: Data from the Web of Science and Scopus databases for November 2019, depth from 1991 to 2018 were used.
    RESULTS: It was revealed that the high level of the publication rating of Russia, which was noted in 1991-1992, has not yet been achieved in the Scopus database for medical rehabilitation. Measures have been identified to enhance it by increasing the growth rate of the Russian publication flow. It also noted the necessity to reduce Russia's dependence on the monopoly of foreign publishing corporations by creating domestic Russian resources and borrowing the experience of foreign colleagues.
    CONCLUSION: The necessary measures should be taken at the level of authors, scientific organizations, the scientific community and the State in order to increase the Russian scientific publication flow in the direction of «Rehabilitation» in foreign top-rated databases. Authors of interdisciplinary articles need to correctly present metadata indicating the relation of the work to the problem of rehabilitation. The necessity is substantiated not only to increase the share of Russian scientific journals in international databases, but also to create domestic high-rating databases, as well as to harmonize the existing regulatory legal acts in regards of terms and definitions in the field of rehabilitation, to bring the headings of the Universal Decimal Classification aligned with the headings of high-ranking international databases. Given the high social significance of the «Rehabilitation» area, it is necessary to include it in the priority list and funded areas at a level corresponding to global trends.

      INTRODUCTION: Precision health is a nascent field of research that would benefit from clearer operationalisation and distinction from adjacent fields like precision medicine. This clarification is necessary to enable precision health science to tackle some of the most complex and significant health problems that are faced globally. There is a pressing need to examine the progress in human precision health research in the past 10 years and analyse this data to first, find similarities and determine discordances in how precision health is operationalised in the literature and second, identify gaps and future directions for precision health research.METHODS AND ANALYSIS: To define precision health and map research in this field, a scoping review will be undertaken and reported according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses - Scoping Review Extension guidelines. Systematic searches of scientific databases (Medline, Embase, Scopus, Web of Science and PsycINFO) and grey literature sources (Google Scholar, Google Patents) identified 8053 potentially eligible articles published from 1 January 2010 to 30 June 2020. Following removal of duplicates, a total of 3190 articles were imported for screening. Article data will be extracted using a customised extraction template on Covidence and analysed descriptively using narrative synthesis.
    ETHICS AND DISSEMINATION: Ethics approval is not required. Findings will be disseminated through professional networks, conference presentations and publication in a scientific journal.

      This study presents data from a content analysis of original research articles published in Journal of Health Communication (JOHC) andHealth Communication (HC) from 2010 to 2019. The authors coded 2,050 articles using categories that identified health topics, theory, population characteristics, and methods used in each study. Distinctions between the published research in JOHCand HCare highlighted. Across both journals, articles are primarily conducted within the United States, most frequently use college student samples, often lack explicit theoretical frameworks, heavily rely on online survey methods, and most commonly use quantitative methodologies. The most frequently utilized theory across both journals wasSocial Cognitive Theory and the most studied health topic were behaviors related to smoking, tobacco, and e-cigarette use. The journals were significantly different in several areas, with HC containing more articles explicitly guided by theory and publishing more qualitative research, while JOHC had more racial diversity in its study samples. Results are discussed in terms of their implications for future research. Increased diversity in methodology and samples, as well as increased use of theory and continued use of interdisciplinary collaborations among researchers will allow for expanding and enhancing health communication knowledge going forward.

      Tissue spheroids consist of a three-dimensional model of cells which is capable of imitating the complicated composition of healthy and unhealthy human tissue. Due to their unique properties, they can bring innovative solutions to tissue engineering and regenerative medicine, where they can be used as building blocks for the formation of organ and tissue models used in drug experimentation. Considering the rapid transformation of the health industry, it is crucial to assess the research dynamics of this field to support the development of innovative applications. In this research, a scientometric analysis was performed as part of a Competitive Technology Intelligence methodology, to determine the main applications of tissue spheroids. Papers from Scopus and Web of Science published between 2000 and 2019 were organized and analyzed. In total, 868 scientific publications were identified, and four main categories of application were determined. Main subject areas, countries, cities, authors, journals, and institutions were established. In addition, a cluster analysis was performed to determine networks of collaborations between institutions and authors. This article provides insights into the applications of cell aggregates and the research dynamics of this field, which can help in the decision-making process to incorporate emerging and innovative technologies in the health industry.

      PURPOSE: Odontogenic sinusitis (ODS) is underrepresented in the literature compared to other forms of rhinosinusitis, specifically in sinusitis guidelines and position statements. ODS publication characteristics could help explain why ODS has received less attention in sinusitis guidelines and position statements. The purpose of this study was to explore trends in the quantity and quality of ODS studies over 3 decades from 1990 to 2019.METHODS: A systematic review was performed to identify all ODS studies from 1990 to 2019. The following variables from all ODS studies were compared between and across the 3 decades: authors' specialties, journal specialties, authors' geographic origins (continents), study topics, study designs, and evidence levels.
    RESULTS: From 1990 to 2019, there were 254 ODS studies that met inclusion criteria. Numbers of publications increased each decade, with 161 being published from 2010 to 2019. Otolaryngologists and dental authors published over 75% of ODS studies each decade, with 60-75% of ODS articles being published in otolaryngology or dental journals. European and Asian authors published the most ODS studies each decade. Overall, 92-100% of ODS publications per decade were level 4 and 5 evidence, with no significant changes between or across decades.
    CONCLUSION: While numbers of ODS publications increased each decade from 1990 to 2019, evidence levels remained low without significant changes over time. Otolaryngologists and dental authors published the majority of ODS studies each decade, with a minority of these studies being multidisciplinary. More ODS studies are needed across all aspects of the condition, and future projects would benefit from improved study designs and multidisciplinary collaboration.

      The Yule-Simpson paradox refers to the fact that outcomes of comparisons between groups are reversed when groups are combined. Using Essential Sciences Indicators, a part of InCites (Clarivate), data for countries, it is shown that although the Yule-Simpson phenomenon in citation analysis and research evaluation is not common, it isn't extremely rare either. The Yule-Simpson paradox is a phenomenon one should be aware of, otherwise one may encounter unforeseen surprises in scientometric studies.

      AIM: The aim of the study was to better understand the scholarship requirements and support for nursing faculty as they work to advance their scholarship and careers.BACKGROUND: Nursing faculty are often required to participate in teaching, service, and scholarship. New faculty often struggle with the scholarship component.
    METHOD: A nationwide Delphi study was conducted, surveying deans and/or associate deans for research at master's and doctoral degree-granting institutions.
    RESULTS: Scholarly requirements provided for faculty to enable development of scholarship were well defined: having a dedicated leader; funding support; a culture of scholarship; publications, presentations, and grant writing expectations; formal programs; mentors; and support.
    CONCLUSION: This study provided a beginning understanding of important aspects of faculty support for scholarship and career development. More information is needed to determine if the support structures and activities described reach faculty and enhance career development.

      OBJECTIVES: The primary objective was to identify the number of residency projects presented at the Pediatric Pharmacy Association (PPA) Bruce Parks Memorial Residency Showcase that were subsequently published. Secondary objectives included a comparison of subsequent publications after residency completion between those who did and did not publish their residency project and an analysis of factors associated with subsequent publications.METHODS: This was a descriptive study including all pediatric-focused resident projects presented at the PPA Bruce Parks Memorial Residency Showcase from 2006 to 2015. Literature searches for all the pediatric-focused residency projects and any subsequent publications were performed. Data collection included residency type (i.e., postgraduate year 1 [PGY1], postgraduate year 2 [PGY2]), project category, and initial position after residency. A zero-inflated Poisson regression was used to analyze subsequent publication status while controlling for other factors. Statistical analyses were performed using SAS/STAT, with a priori p value < 0.05.
    RESULTS: There were 434 projects presented by 401 residents. Seventy-four (17.1%) were published, with the majority being PGY2s (74.3%). Subsequent publications were identified for 162 residents (40.4%), with a higher percentage in those who published their pediatric-focused residency project versus those who did not, 59.5% versus 32.8%, p < 0.001. Factors associated with subsequent publications were those who published their residency project, initial position in academia, and PGY2s.
    CONCLUSIONS: Of the residency projects presented at the showcase <20% were subsequently published. Those who published their residency research project were more likely to have subsequent publications. Future efforts should be taken to ensure that residents have the tools/confidence to independently publish their research/scholarship.
