      OBJECTIVES: To access the trends and focuses of publications on public health emergency preparedness in the timeframe 1997-2019.METHODS: Publications related to public health emergency preparedness (PHEP) were retrieved from the Web of Science Core Collection database. Bibliometric analyses including output statistics, co-authorship analysis, citation analysis, co-citation analysis, and co-occurrence analysis were performed and mapped using VOSviewer.
    RESULTS: A total of 1058 publications on PHEP were included in this study. There was an increasing trend of publication output and citations since 2002. A total of 4605 authors from 1587 institutes and 92 countries contributed to the publications, and the United States lead the field. Disaster Medicine and Public Health Preparedness was the most active and co-cited journal among 243 journals. The knowledge foundation mainly focused on the professionals' capacity, education, and conceptions of PHEP. Epidemics, natural disasters, terrorism, education, and communication were the principle topics; while "vulnerable populations," "disaster medicine," and "hurricane" were the recent hotspots in this field.
    CONCLUSIONS: Significant progresses had been achieved worldwide in the past 2 decades, however, improvement of research activity and international collaboration is still a need for most countries.

      PURPOSE: The purpose of this study was to analyze articles published in the Journal of the Korean Academy of Nursing (JKAN) between 2010 and 2019, along with those published in three international nursing journals, to improve JKAN's international reputation.METHODS: The overall characteristics of JKAN's published papers and keywords, study participants, types of nursing interventions and dependent variables, citations, and cited journals were analyzed. Additionally, the keywords and study designs, publication-related characteristics, journal impact factors (JIF), and Eigenfactor scores of International Journal of Nursing Studies (IJNS), International Nursing Review (INR), Nursing & Health Sciences (NHS), and JKAN were analyzed and compared.
    RESULTS: Among the four journals, JKAN's score was the lowest in both the journal impact factor and Eigenfactor score. In particular, while the JIF of INR and NHS has been continuously increasing; JKAN's JIF has remained static for almost 10 years. The journals which had cited JKAN and those which JKAN had cited were mainly published in Korean.
    CONCLUSION: JKAN still has a low IF and a low ranking among Social Citation Index (E) journals during the past 10 years, as compared to that of four international journals. To enhance JKAN's status as an international journal, it is necessary to consider publishing it in English and to continuously improve the conditions of other publications.

      INTRODUCTION: Publication rates for studies reported at French Arthroscopic Society (Société francophone d'arthroscopie, SFA) meetings are not known. A comprehensive search of podium presentations to the 2014 SFA meeting was performed, assessing: (1) publication rate for meeting abstracts, and (2) bibliometric parameters including journal Impact Factor.HYPOTHESIS: The full-text publication rate for abstracts accepted for the 2014 French Arthroscopic Society (SFA) meeting was around 47.1%: i.e., the rate reported for the 2013 meeting of the French Society of Orthopedic Surgery and Traumatology (SoFCOT).
    MATERIAL AND METHODS: Bibliometric analysis of all abstracts accepted for the 2014 SFA annual meeting was undertaken by the Junior French Arthroscopic Society (SFA Junior), who collated the podium presentations. Reported studies were retrospective in 43 cases (54%) and prospective in 36 (46%). They consisted in clinical studies in 52/79 cases (66%), experimental studies in 4 (5%), cadaver or animal studies in 13 (16.5%), epidemiological studies in 8 (10%), a case report in 1 (1.2%) and a literature review in 1 (1.2%). Thirty-two (40.5%) concerned the shoulder and 31 (39%) the knee. Publication was checked on systematic PubMed-Medline search of authors' names. Articles found on PubMed-Medline were downloaded into the SIGAPS scientific publication search, management and analysis system database. Journal impact factor and SIGAPS category (A to E) were obtained, as were number of citations and h-index. This was a descriptive study, assessing numbers; results were reported as number and percentage.
    RESULTS: Overall publication rate was 31/79 (39.2%): 20/31 clinical studies (64.5%), 6 cadaver studies (19.4%), 3 epidemiology studies (9.7%), 1 experimental study (3.2%) and 1 literature review (3.2%). Mean 2014 SFA meeting-to-publication time was 18.7 months [range, -2 to 60 months]. Journal SIGAPS categories were A for 4 articles (13.3%), B for 13 (43.3%), C for 3 (10%), D for 9 (30%), with no E category articles but 1 article (3.3%) without SIGAPS category.
    CONCLUSION: The publication rate for abstracts accepted for report to the 2014 SFA annual meeting was lower than for the 2013 SoFCOT meeting. The high level of the journals in question testified to the quality of the studies reported at the SFA meeting.

      INTRODUCTION: Female researchers are underrepresented in academic surgery. While they are increasingly producing original research, they lag male researchers in productivity. This disparity is not well understood within the nascent field of global surgery. The following study examines gender parity in global surgery research presented at the Academic Surgical Congress and within subsequent publications.METHODS: Abstracts presented at the Academic Surgical Congress (ASC) between 2015 and 2019 in "Global Surgery" sessions were reviewed to obtain title, the first author (FA) and senior author (SA). The authors were classified by gender. The Scopus database was queried by two reviewers for abstracts with corresponding publications, citations, and journal impact factors. Statistical analysis was conducted using chi-square analysis and t-tests where appropriate.
    RESULTS: Of a total of 6635 abstracts, 218 global surgery abstracts over a 5-year period were identified. Of these abstracts, 96 (44%) had female FAs, while 56 (26%) had female SAs. When comparing gender, female (44%) FAs and male (56%) FAs were equally represented. While SAs were significantly less likely to be female (26% versus 74%, P < 0.0001), female senior authorship increased significantly within the study period. Output with respect to publications, citations, and journal impact factors were equal by gender.
    CONCLUSIONS: This study presents 5 y of gender trends in global surgery scholarly work presented at the ASC. Despite an overall predominance of male senior authors, the paradigm is shifting with a recent trend to gender parity. Male and female authors have equal output and are equally impactful. Findings of gender equity in academic global surgery are encouraging, and further study of other disciplines are warranted.

      INTRODUCTION: Scientometric studies help scientists to identify research gaps and plan future research. There is no scientometric assessment of research on childhood onset type 1 diabetes (T1D), despite an intensive research in this field over the past 2 decades.AIM OF THE STUDY: To provide a scientometric assessment of global research output in pediatric T1D.
    MATERIAL AND METHODS: Publications on pediatric T1D indexed in Scopus database over the 20-year period from 2000 to 2019 were examined. The most productive and impactful countries, organizations and authors, trends in research, the media of publications and characteristics of high cited publications were identified using appropriate bibliographic tools.
    RESULTS: Pediatric T1D research registered 7.84% and 79.99% annual and 10-year cumulative growth and averaged 19.35 citations per paper (CPP). The field witnessed an uneven participation of 141 countries, wherein 82.67% of the global research output share came from top 10 countries. USA leads the ranking with 29.76% share, followed by UK (10.56%), Germany, Italy, Sweden and Australia (5.15% to 7.88%), and Poland, Finland, Canada and Denmark (3.04% to 4.24%). Five countries which registered relative citation index (RCI) higher than their group average of 1.63 were Finland (2.30), UK (1.82), Canada (1.77), Denmark and USA (1.74 each). The number of participating organizations and authors was 3627 and 5596 respectively.
    CONCLUSIONS: The USA and Finland are the most productive and the most impactful countries respectively in global pediatric T1D research. The contribution from developing countries especially from Southeast Asia is meager despite a large disease burden.

      OBJECTIVE: The use of bibliometric indicators to measure the quality of scientific journals is a general practice in all areas of science. The WoS and Scopus databases continue to be the reference sources to obtain bibliographic indicators. Others such as SciELO network offer indicators about Ibero-American science, which are scarcely collected in WoS and Scopus. The aim of this work was to analyze the association of the indicators proposed by SciELO for health sciences journals, with the most widely used impact and indicators and to study the complementarity of the existing prestige indicators.METHODS: Analytical correlational study between SciELO indicators, with impact and prestige indicators from Journal Citation Report, Scopus and Web of Science. The results refer to 2018, the most recent and complete data available. Association between the qualitative variables was analyzed using the chi-square test, and the analysis of variance (ANOVA) was performed for the quantitative variables using the Tukey method as a post hoc test. To obtain the relationship between quantitative variables, Pearson's correlation coefficient was used and Spearman's coefficient for ordinal variables. The level of significance used in all the hypothesis tests was α≤0.05.
    RESULTS: The SciELO Impact Factor showed a weak correlation both, with Journal Citation Report (R=0.36; p=0.003), and Scopus Cite Score (R=0.39; p=0.001). The association between the H index of the Web of Science andthe H index of Scopus with the H index of SciELO was weak in both cases (R=0.45; p<0.001 and R=0.340; p=0.003).
    CONCLUSIONS: Indicators proposed by SciELO, for health journals, did not show an association with those of WoS or Scopus. The weak correlation between Impact Factor and Cite Score with SciELO Impact Factor, converts the latter into a necessary "metrics" to assess journals excluded from the "mainstream" and fundamentally those from the Latin American region. The need of using the prestige indicators to fill in the impact indicators, has not been proven in this study.

      PURPOSE: To assess the online attention to research in the field of paediatric dentistry in relation to publication details and citations.METHODS: The articles were identified by a search performed through the Dimensions Free App. The search included the six journals related to paediatric dentistry listed in the SCImago Journal and Country Rank. The 200 articles with the highest AAS (Altmetric Attention Score) were collected and screened for data related to publication, authorship, and research topic. Citations were harvested from WOS (Web of Science) and Scopus.
    RESULTS: The 86.3% of the 200 articles belonged to only two of the journals: the International Journal of Paediatric Dentistry and the European Archives of Paediatric Dentistry. The 53.5% of the articles were published between 2014 and 2019. The mean AAS was 8.3. Cross-sectional studies were the most prevalent study design. AAS did not correlate to the number of citations as reported in WOS and Scopus.
    CONCLUSIONS: Online attention to research in paediatric dentistry can be improved. According to the topic, erosion studies displayed high visibility. The classic citation count in combination with the AAS offers a more comprehensive insight iinto research. The online profile of journals and their social media dissemination policies should be improved to facilitate the spread of research information in scholar and non-scholar audiences through the web.

      BACKGROUND: The Royal College of Nursing (RCN) initiated a fellowship programme in 1976 as a means of recognising outstanding registered nurses who have demonstrated a commitment to advancing the art and science of the profession and the improvement of healthcare.AIM: To conduct a bibliometric analysis of the scholarly output of RCN fellows, thereby documenting their coverage, connectivity and contribution to the indexed professional literature.
    METHOD: This study used a mixed-methods approach, analysing publicly available data to identify and report thematic and quantitative measures of the scholarship of fellows through the application of bibliometric analysis.
    RESULTS: In total, 193 fellowships were awarded between the inception of the scheme in 1976 and 2019. Collectively, fellows have 9,336 publications indexed in Scopus and have accrued 131,408 citations resulting from 116,961 citing articles. Overall, 166 fellows produced one or more indexed articles. The 166 fellows engaged 9,908 co-authors in the production of this work from a total of 72 countries or territories. The work of the fellows covers 24 themes that include major healthcare priorities and a variety of clinical settings, as well as themes essential to the advancement of the nursing profession and the quality of services.
    CONCLUSION: While there are limitations to this study in terms of its coverage of the indexed database, it has established a useful baseline of the published scholarship contributions of RCN fellows. The contributions made reflect the original intent of the RCN fellowship award - to acknowledge nurses who have demonstrated a commitment to advancing the art and science of the profession and the improvement of healthcare.

      PURPOSE: To analyze the state of scientific publications in multifocal contact lenses field through a bibliometric study.METHODS: The database used to carry out the study was SCOPUS and contained the descriptors "multifocal contact lens", "bifocal contact lenses", "progressive contact lenses" and "presbyopia contact lenses", limited to the fields of title, keywords and abstract. The indicators applied in this research were: doubling time and annual growth rate, Price's transience index, Lotka's law of scientific productivity, and Bradford's zones.
    RESULTS: A total of 346 articles were published between 1960 and 2019. The growth in the number of publications matches the exponential adjustment slightly better (R = 0.53). The duplication time was 13.2 years. The productivity level is focused on articles with an average number of authors of just 2.06 per article. The Bradford core was formed by two journals, Optometry and Vision Science and Eye and Contact Lens.
    CONCLUSIONS: Research on multifocal contact lenses has exponential growth, without evidence of having reached a saturation point. The main countries in scientific production in this field are the United States and Australia.

      BACKGROUND: Paediatric resuscitation is rare but potentially associated with maximal lifetime reduction. Notably, several nations experience high infant mortality rates even today. To improve clinical outcomes and promote research, detailed analyses on evolution and current state of research on paediatric resuscitation are necessary.METHODS: Research on paediatric resuscitation published in-between 1900 and 2019 were searched using Web of Science. Metadata were extracted and analyzed based on the science performance evaluation (SciPE) protocol. Research performance was evaluated regarding quality and quantity over time, including comparisons to adult resuscitation. National research performance was related to population, financial capacities, infant mortality rate, collaborations, and authors' gender.
    RESULTS: Similar to adult resuscitation, research performance on paediatric resuscitation grew exponentially with most original articles being published during the last decade (1106/1896). The absolute number, however, is only 14% compared to adults. The United States dominate global research by contributing the highest number of articles (777), Hirsch-Index (70), and citations (18,863). The most productive collaboration was between the United States and Canada (52). When considering nation's population and gross domestic product (GDP) rate, Norway is leading regarding population per article (62,467), per Hirsch-Index (223,841), per citation (2226), and per GDP (2.3E-04). Regarding publications per infant mortality rate, efforts of India and Brazil are remarkable. Out of the 100 most frequently publishing researchers, 25% were female.
    CONCLUSION: Research efforts on paediatric resuscitation have increased but remain underrepresented. Specifically, nations with high infant mortality rates should be integrated by collaborations. Additional efforts are required to overcome gender disparities.

      Water conservation and soil retention are two essential regulating services that are closely related, and their relationship might produce synergies or trade-offs. Distinguishing the current status and evolution of research in this field could provide a scientific foundation for subsequent research. "Water conservation" and "soil retention" were selected as keywords for a search of Web of Science for publications during 1976-2018. A total of 4489 periodical articles were obtained. Using bibliometric and social network analysis tools, the scientific output performance, national research contributions, potential hot topics, and connections between keywords and the levels of cooperation between countries at different stages were explored to reveal the related development trends. The results showed that the literature on water conservation and soil retention increased rapidly, especially after 2008. The USA, China, and India were the most productive countries, and the USA, the UK, and Canada were the most influential countries regarding international cooperation. Agriculture, water resource utilization, water-soil erosion, and ecosystem services were closely related topics, and the connections between these topics have increased since 1998. In addition to sustainability, the response of water conservation and soil retention to global environmental change, such as water resource management, land use, and land conservation, are potential emerging research hotspots.

      In December 2019, an outbreak of pneumonia, which was named COVID-2019, emerged as a global health crisis. Scientists worldwide are engaged in attempts to elucidate the transmission and pathogenic mechanisms of the causative coronavirus. COVID-19 was declared a pandemic by the World Health Organization in March 2020, making it critical to track and review the state of research on COVID-19 to provide guidance for further investigations. Here, bibliometric and knowledge mapping analyses of studies on COVID-19 were performed, including more than 1,500 papers on COVID-19 available in the PubMed and China National Knowledge Infrastructure databases from January 1, 2020 to March 8, 2020. In this review, we found that because of the rapid response of researchers worldwide, the number of COVID-19-related publications showed a high growth trend in the first 10 days of February; among these, the largest number of studies originated in China, the country most affected by pandemic in its early stages. Our findings revealed that the epidemic situation and data accessibility of different research teams have caused obvious difference in emphases of the publications. Besides, there was an unprecedented level of close cooperation and information sharing within the global scientific community relative to previous coronavirus research. We combed and drew the knowledge map of the SARS-CoV-2 literature, explored early status of research on etiology, pathology, epidemiology, treatment, prevention, and control, and discussed knowledge gaps that remain to be urgently addressed. Future perspectives on treatment, prevention, and control are also presented to provide fundamental references for current and future coronavirus research.

      INTRODUCTION: In recent decades, progress has been made in tackling inequality between men and women, encouraging publications that analyse and provide recommendations to eliminate this issue. The aim of this study is to analyse the gender differences in the authorship of the studies published in the journal Acta Otorrinolaringológica Española.METHODS: A cross-sectional study of issues published between January 2010 and December 2019, including number of authors (total, men and women), type and year of publication, institution and country (first, second and last author), and area of specialisation. Women's participation was calculated based on female/male ratio, trend and associated factors.
    RESULTS: A total of 615 articles with 2,841 authors (1,017 women and 1,824 men) from Spain were collected. A total of 244 (39.7%) women and 371 (60.3%) men were listed as first authors (P=.879), 245 (39.84%) women and 370 (60.16%) men as second authors (P=.919), and 137 (22.28%) women and 478 (77.72%) men as final signatories (P<.000). All the ratios calculated were below the recommended figures.
    DISCUSSION: The participation of female authors in the scientific production of Acta Otorrinolaringológica Española is acceptable, following a similar distribution to the current number of female ENT specialists. Further efforts are needed to increase the number of final signatories and to change the decreasing trend recorded over the last decade.

      BACKGROUND: Research productivity is critical to academic surgery and essential for advancing surgical knowledge and evidence-based practice. We aim to determine if surgeon affiliation with top US universities/hospitals (TOPS) is associated with increased research productivity measured by numbers of peer-reviewed publications in PubMed (PMIDs).METHODS: A bibliometric analysis was performed for PMIDs. Affiliated authors who published in trauma surgery (TS), surgical critical care (SCC), acute care surgery (ACS), and emergency general surgery (EGS) were evaluated for publications between 2015 and 2019, and lifetime productivity. Our analysis included 3443 authors from 443 different institutions. Our main outcome was PMIDs of first author (FA) and senior author (SA) in each field (2015-2019) and total lifetime publications.
    RESULTS: Significant differences exist between PMIDs from TOPS vs non-TOPS in FA-TS (1.34 vs 1.23, P = .001), SA-TS (1.71 vs 1.46, P < .001), total SA-PMIDs (44.10 vs 26.61, P < .001), and SA-lifetime PMIDs (90.55 vs 59.03, P < .001). There were no significant differences in PMIDs for FA or SA-SCC, FA or SA-ACS, FA or SA-EGS, FA-total PMIDs 2015-2019, or FA-lifetime PMIDs (P > .05 for all).
    CONCLUSION: There were significantly higher TS PMIDs among FAs and SAs affiliated with top US institutions in 2015-2019, along with higher total PMIDs (2015-2019) and lifetime PMIDs. These findings are of significance to future graduate medical applicants and academic surgeons who need to make decisions about training and future career opportunities.

      The realm of social health has not yet been properly established in terms of fixed definitions, concepts, and research areas. This study attempts to define social health using macro and micro perspectives and explores trends in social health research by mapping their topics and fields. We used Latent Dirichlet allocation (LDA) topic modeling, which allows the extraction of key terms and topics derived from a large volume of literature. We traced the evolution of research topics from past (the literature that "present" articles cited), present (existing journal articles on social health), to future (the literature which cited the articles) studies based on connections between citations. The datasets were collected by the query terms "social health" in the Scopus database, including title, abstract, and keywords of journal articles. We collected a total of 443 articles from recent social health literature, 6588 articles from past literature that the recent articles on social health cited, and 2680 articles from future literature in which recent social health articles were cited. We defined social health as positive interaction that increases individual engagement in social life at the micro level, and the high degree of social integration that deals with collective problems in society at the macro level. The results of LDA showed that social health research has developed into seven fields: Health Care Delivery; Vulnerable Groups; Measurement; Health Inequality; Social Network and Empowerment; Clinical/Physical Health; and Mental/Behavioral Health. Based on citation relationships, topics grounded in an individual/micro perspective have grown increasingly specialized and productive, while topics grounded in a social/macro perspective have stagnated or was underexplored. Our findings imply that social health studies should follow a more interdisciplinary approach to integrate current health models of individual-centered treatments with social science concerns on building collective capacity for social well-being.

      INTRODUCTION: The objectives of this study were to quantify adoption of social media for the dissemination of original research in orthopaedic research and to determine the correlation between academic citations and social medial posts among recent orthopaedic publications.METHODS: An Internet-based study was performed of 835 articles from three orthopaedic journals from 2018 to 2019. The number of academic citations for each article was determined using Google Scholar and Web of Science. The number of social media posts was determined using Twitter. The correlation between academic citations and social media posts was calculated using the Spearman rank correlation coefficient.
    RESULTS: The average number of academic citations per article was 4.6 on Google Scholar and 2.6 on Web of Science. The average number of social media posts per article was 3.6, which consisted of 1.1 tweets and 2.5 retweets. The number of academic citations per article was weakly correlated with the number of social media posts, tweets, and retweets.
    DISCUSSION: There is a positive relationship between social media posts and academic citations of recent orthopaedic research. Use of social media differs among journals and authors, which may represent opportunities to leverage social media platforms to more effectively dissemination novel research findings.

      This paper aims to draw lessons from retrospectively evaluating the evolution of the air transport discipline right up to the COVID-19 outbreak through the Journal of Air Transport Management (JATM), the main scholarly air transportation journal globally. As such, this study deploys a comprehensive bibliometric analysis and graphical mapping of the JATM knowledge body through CiteSpace visualization of 1483 JATM papers from 2001 to 2019. Our results suggest that while the industry has experienced pandemics and economic crises in the past, both were not dominant in influencing JATM literature neither in frequency nor in impact. That said, recovery, crisis and disruption are important key words in JATM papers not just in regard to safety and economic crisis management but increasingly also related to health concerns with recent key papers published in the pandemic and recovery management context which may have helped the industry dealing with the current crisis as well as current JATM papers on this topic assisting with preparing for a transitioning out of COVID-19 world.

      Retraction of research articles is increasing but the reasons and characteristics of retractions involving authors from Africa have not been studied. Using records from the Retraction Watch database, we analyzed information on articles retracted between 2014 and 2018 with at least one author or co-author affiliated with an institution in the African region to determine the most prevalent types of misconduct, subject fields, and the characteristics of researchers or research teams associated with retraction. Plagiarism was the most frequent form of misconduct, followed by duplication. International collaboration was associated with fewer retractions for plagiarism and errors in data, but increased retractions due to authorship issues. Teams with at least one senior member were associated with fewer retractions due to plagiarism but more due to duplication of articles. We conclude by making recommendations for best practice, further research, and highlighting implications for education.

      OBJECTIVE: To evaluate trends in female authorship in the recent urologic literature.METHODS: We examined articles published in 2012 and 2017 from five urologic journals: Journal of Urology (JU), Journal of Endourology (JE), Neurourology and Urodynamics (NU), Urologic Oncology (UO), and Urology (UR). Gender was recorded for first, supplemental, and last authors. Articles were further categorized by subspecialty focus of the published article. Chi-square tests and multiple logistic regression modeling were used to assess for differences in female authorship by year, journal, and article subspecialty.
    RESULTS: 1,433 and 1,374 articles were published in 2012 and 2017, respectively. There was a significant increase in all female authorship categories between years: first (19% to 25%), last (12 to 16%), and any (67% to 74%) (p<0.01, all). By journal, the highest proportion of articles with any female authors for both years was in NU (80%, 2012; 85%, 2017) while lowest was in JE (49%, 2012; 54%, 2017). Likewise, female authorship was generally higher in female/voiding dysfunction /incontinence (FVI) and lower in endourology subspecialty articles. Controlling for journal and subspecialty, multiple logistic regression analysis showed no change in last authorship between years.
    CONCLUSION: Overall female authorship in the urologic literature has increased in recent years. However, after controlling for journal and subspecialty we found no increase in female last authorship between years, suggesting that disparities in senior authorships exist based on journal and subspecialty topic. Our findings further suggest an authorship plateau, highlighting the importance of efforts to optimize advancement and promotion of women in academic urology.

      PURPOSE: The confidence in a study will be reduced due to the incorrect representation of statistical results. However, it is unknown to what extent p values are incorrectly represented in published nursing journals. The study aims to evaluate the articles in 30 nursing journals in terms of the error in reporting of p values (p = .000).DESIGN AND METHODS: This was a bibliometric analysis. All papers published in 10 leading nursing journals (between 2015 and 2019), the 10 bottom nursing journals (2019), and 10 selected key nursing journals (2019) indexed in the Science Citation Index Journal Citation Reports were reviewed to detect errors in reporting of p values (p = .000).
    RESULTS: A total of 3,788 papers were reviewed. Notably, it was found that 93.3% (28/30) of the nursing journals contained incorrect representation of p values (p = .000). The reporting rate of these journals ranges from 0% to 57.1%, with an overall rate of 12.8% (486/3,788). In addition, the rate of incorrect representation of p values (p = .000) showed no statistically significant difference between different publication years (Χ2 = 4.976, p = .290). However, the rate of reporting was different between study types, journals, and regions (p = .007, p = .020, and p < .001, respectively).
    CONCLUSIONS: The incorrect representation of p values is common in nursing journals.
    CLINICAL RELEVANCE: We recommend that both publishers and researchers be responsible for preventing statistical errors in manuscripts. Furthermore, various kinds of statistical training methods should be adopted to ensure that nurses and journal reviewers have enough statistical literacy.

      BACKGROUND:  This study was designed to evaluate the publication performance of management teams consisting of chief and senior physicians in German university cardiac surgery units over a 10-year period and to facilitate benchmarking.METHODS:  The cutoff date for consideration of staffing from the unit Web site and publications was July 1, 2017. The literature search was based on an evaluation of the PubMed database. The 5-year impact factor (IF) from 2016 was assigned to each journal.
    RESULTS:  Two thousand five hundred thirty-five publications (average IF 3.02) were registered, published in 323 journals. Of a total of 341 management team members, 235 (68.9%) published as first or last author over the 10-year period. The number of publications from the units divided into quintiles varied considerably with the first six units contributing 39.0% of all publications and the last nine units 9.4%. With a cumulative IF total of 3265, the publications of the first six units accounted for 42.7% of the cumulative IF, the last unit quintile amounted to 621 (8.1%) of the cumulative IF. When considering publications per managing member, the first quintile averaged 11.9 publications (29.6 IF) per managing member, the last quintile 3.3 publications (8.0 IF) per member.
    CONCLUSIONS:  The six units of the first quintile published on average 3.6 times more per managing member than the nine units in the last quintile and the average cumulative IF per member in the first quintile was almost five times higher. Further investigation must show whether this considerable difference in publication activity between the university units is also observed in other operative fields.

      BACKGROUND: Military veterans (veterans, in short), due to their unique military experience, face a variety of health issues either unique to their service or more common than the general population. This study aims to achieve a better understanding of the publications focused on veterans from 1989 to 2018 using a PubMed-based bibliometric analysis of research articles on veterans.METHODS: We searched the PubMed website for publications in journal article category from 1989 through 2018, indexed with the MeSH descriptor, "Veterans" or 'Veterans Health'. Recorded articles were retrieved and analyzed.
    RESULTS: During the period 1989-2018, there were 12,710 articles related to veterans or veterans' health, up from 66 articles in 1989 to 1,225 articles in 2018. Of all the selected articles, 5,242 (41.24%) can be classified under research support by the US government, 2,773 (21.81%) by non-US government, and 1,700 (13.38%) by the Office of Extramural Research (OER) of the NIH. Out of the 15 most prolific authors, 14 were affiliated with the US institutions. The journal that published the highest number of articles related to veterans was the journal Military Medicine (504 articles, 3.97%), followed by the Journal of Traumatic Stress (397 articles, 3.12%), Psychiatric Services (Washington, D.C.) (299 articles, 2.35%), and Journal of Rehabilitation Research and Development (279 articles, 2.20%). Among all publications, 18.04% (n=2,293) were published in journals of psychiatry, followed by 13.51% (n=1,717) of psychology and 7.71% (n=980) of neurology.
    CONCLUSION: Publications related to veterans increased significantly from 1989 to 2018. A considerable number of the publications were in journals of psychiatric and psychological categories. However, most publications were descriptive of U.S veterans. Future research related to veterans in Taiwan deserves further exploration to provide a reference for prioritization of the health care and policy making.
