      BACKGROUND: To describe the impact of research, beyond the limits of the academic environment, Altmetric, a new social and traditional media metric was proposed. The aims of this study were to analyze the online activity related to orthodontic research via Altmetric and to assess if a correlation exists among citations, Mendeley reader count, and the AAS (Altmetric Attention Score).METHOD: The Dimensions App was searched for articles published in the orthodontic journals listed in the Journal Citation Reports (JCR) throughout the years 2014 to 2018. The articles with a positive AAS were collected and screened for data related to publication and authorship. The articles with an AAS higher than 5 were screened for research topic and study design. Citation counts were harvested from Web of Science (WOS) and Scopus.
    RESULTS: The best performing journals were Progress in Orthodontics and the European Journal of Orthodontics with a mean AAS per published item of 1.455 and 1.351, respectively and the most prevalent sources were Tweets and Facebook mentions. The most prevalent topic was Oral Health-Related Quality of Life (OHRQOL) and the study design was systematic reviews. The correlation between the AAS and the citations in both WOS and Scopus was poor (r = 0.1463 and r = 0.1508, p < .05). The correlation between citations count and Mendeley reader (r = 0.6879 and r = 0.697, p < .05) was moderate.
    CONCLUSIONS: Few journals displayed a high level of web activity. Journals and editors should enhance online dissemination of the scientific outputs. The authors should report the impact of the findings to the general public in a convenient way to facilitate online dissemination but to avoid an opportunistic use of the research outputs. Despite the lack of correlation, a combination of the citation count and the AAS can give a more comprehensive assessment of research impact.

      The globalization of medical research and global health's increasing popularity worldwide have resulted in greater geographic, ethnic, and socioeconomic diversity of studies published in the scientific literature. Yet the geographic distribution, authorship representation, and subject trends among Low-/Low-Middle-Income Country (LIC/LMIC)-based scientific publications remain largely unknown. This analysis assesses these gaps in knowledge. We performed a comprehensive bibliometric analysis of all scientific articles published between January 2014 and June 2016 in the four most prominent general medicine and five most prominent general global health journals based on impact factor. The African region, containing 24% of the global LIC/LMIC population, accounted for 49.9% of all publications. Corresponding authors with either exclusive or joint appointment to a LIC/LMIC institution were present in 26.2% of all included articles. Over one-quarter (28.8%) of all publications did not list a local author. Nearly two-thirds (62.1%) of articles published in global health journals and roughly half (52.4%) in general medicine journals involved infectious diseases. Non-HIV infectious disease studies were by far the most frequent subject areas across all journals. The trends identified in this study may help to inform the evolution and prioritization of future research efforts, thereby allowing global health to remain truly global.

      Objective: Publications are the cornerstone of the dissemination of scientific innovation and scholarly work, but published works are mostly behind paywalls. Therefore, many researchers and institutions are searching for alternative models for disseminating scholarly work that bypasses the current structure of paywalls. This study aimed to determine whether a self-published open access (OA) journal, the International Journal of Health Sciences (IJHS), has been able to reach a global audience in terms of authorship, readership, and impact using the OA model.Methods: All IJHS articles were retrieved and analyzed using scientometric methods. Using the keywords from abstracts and titles, unsupervised clustering was performed to map research trends. Network analysis was used to chart the network of collaboration. The analysis of articles' metadata and the visualizations was performed using R programming language.
    Results: Using Google Scholar as a source, the general statistics of IJHS from inception to 2019 showed that the average citation per article was 11.29, and the impact factor of the journal was 2.28. The results demonstrate the obvious local and global impact of a locally published journal that allows unrestricted OA and uses an open source publishing platform. The journal's success at attracting diverse topics, authors, and readers is a testament to the power of the OA model.
    Conclusions: Open source is feasible and rewarding and enables a global reach for research from under-represented regions. Local journals can help the Global South disseminate their scholarly work, which is frequently ignored by commercial and established publications.

      Dye decolourizing peroxidase (DyP) is an emerging biocatalyst with enormous bioremediation and biotechnological potentials. This study examined the global trend of research related to DyP through a bibliometric analysis. The search term "dye decolourizing peroxidase" or "DyP-type peroxidase" was used to retrieve published articles between 2007 and 2019 from the Web of Science (WoS) and Scopus databases. A total of 62 articles were published within the period, with an annual growth rate of 17.6%. The highest research output was observed in 2015, which accounted for about 13% of the total output in 12 years. Germany published the highest number of articles (n=10, 16.1%) with a total citation of 478. However, the lowest number of published articles among the top 10 countries was observed in India and Korea (n= 2, 3.2%). Research collaboration was low (collaboration index= 4.08). In addition to dye decolourizing peroxidase(s) and DyP-type peroxidase(s) (n=33, 53.23%), the top authors keywords and research focus included lignin and lignin degradation (n=10, 16.1 %). More so, peroxidase (n=59, 95.2%), amino acid sequence (n=27, 46.8%), lignin (n=24, 38.7%) and metabolism (n=23, 37.1%) were highly represented in keywords-plus. The most common conceptual framework from this study include characterization, lignin degradation and environmental proteomics. Apart from the inherent efficient dye-decolourizing properties, this study showed that DyP has emerging biotechnological potentials in lignin degradation and remediation of phenolic environmental pollutants, which at the moment are under explored globally.

      PURPOSE: The aim of this study is to investigate the emergence and development of sarcopenia research and guide to most cited articles for researchers.METHODS: Thomson Reuters' Web of Science database was used to search for all articles related to the term 'sarcopenia'. We also benefited from PubMed to find additional data about these articles. We analyzed the top 100 cited articles (T100) by topic, types of research methods, keywords, journal, author, year, institution, and average number of citations per year, as well. Correlations were also made between the total number of citations, the average number of citations per year (ACpY), impact factors, and the time period of publication.
    RESULTS: The median number of citations for the most cited articles was 309 (range is from 213 to 4,082). The most investigated topics of sarcopenia were definition-diagnosis (n = 35), prognosis (n = 19), and treatment-recommendation (n = 11). The European Working Group on Sarcopenia in Older People (EWGSOP) consensus definition published in 2010 had the highest total number of citations and ACpY. The most common types of research method, country, year, and keyword were epidemiological studies (n = 55), USA (n = 69), 2010 (n = 13), and sarcopenia (n = 39), respectively. No correlation exists between impact factor (IF) and number of citations or IF and ACpY.
    CONCLUSION: Despite some flaws, this study identifies the most significant contributions to sarcopenia research and reveals many important scientific breakthroughs and landmarks that took place over the years.

      PURPOSE: The aim of this study was to review the top 100 most-cited articles in Ophthalmology in Asia since 1970.METHODS: The Scopus database was used to identify the top 100 most-cited ophthalmology articles published in ophthalmology (T100-Eye) and nonophthalmology (T100-General) journals.
    RESULTS: The T100-Eye articles were published between 1982 and 2015, and T100-General from 1982 to 2017. T100-Eye had higher citations [median (range) = 317 (249-1326)] than T100-General [158 (105-2628)], but T100-General were published in journals with higher impact factor (IF) than T100-Eye (median IF= 5.5 vs 4.4) and produced more landmark papers (3 vs 1 articles that were cited >1000 times). Fifty-five % of T100-Eye were published in 3 journals: Ophthalmology (n = 22), Investigative Ophthalmology and Visual Science (n = 17), and American Journal of Ophthalmology (n = 16). T100-Eye had 88 original research articles and 12 reviews, whereas T100-General had 84 original research and 16 reviews. The most-frequent studied disease categories were myopia (n = 16) and age-related macular degeneration (n = 15) in T100-Eye and diabetic retinopathy (n = 24) and glaucoma (n = 16) in T100-General. Japan and Singapore contributed most to T100-Eye (n = 42, n = 17) and T100-General (n = 36, n = 26) articles. More than 80% and 95% of first and last authors were male in both lists. Emerging research topics were optical coherence tomography in T100-Eye and artificial intelligence in T100-General.
    CONCLUSIONS: Our citation analysis reveals differences in the focus of research topics of top-cited ophthalmology articles published in ophthalmology and nonophthalmology journals in Asia. It highlights that certain eye diseases are studied more in Asia and shows the contribution of specific countries to highly cited publications in ophthalmology research in Asia.

      Background: Within the past decade, Africa has faced several recurrent outbreaks of Ebola virus disease (EVD), including the 2014-2016 outbreak in West Africa and the recent 2018-2020 Kivu outbreak in the Democratic Republic of Congo. The study thus aimed at quantifying and mapping the scientific output of EVD research published within 2010-2020 though a bibliometric perspective.Methods: EVD-related publications from 2010 to 2020 were retrieved from the Web of Science (WoS) and Scopus databases by using the keywords 'Ebola', 'Ebola Virus Disease', 'Ebolas', and 'ebolavirus'. Biblioshiny software (using R-studio cloud) was used to categorise and evaluate authors', countries' and journals' contribution. VOSviewer was used for network visualisation.
    Results: According to the used search strategy, a total of 3865 and 3848 EVD documents were published in WoS and Scopus, respectively. The average citation per document was 16.1 (WoS) and 16.3 (Scopus). The results show an overall increase in the publication trend within the study period. The leading countries in EVD research were the USA and UK, with over 100 papers in both databases, including Nigeria and South Africa. NIAID and CDC-USA were the most influential institutions, while "Infectious Diseases" and "Medicine" were the most decisive research fields. The most contributing authors included Feldmann H and Qiu XG with over 60 papers in each database, while Journal of Infectious Diseases was the most crucial journal. The most cited article was from Aylward et al. published in 2014, while recent years displayed a keyword focus on "double-blind", "efficacy", "ring vaccination" and "drug effect".
    Conclusion: This bibliometric analysis provides an updated historical perspective of progress in EVD research and has highlighted the role played by various stakeholders. However, the contribution of African countries and institutions is not sufficiently reflected, implying a need for increased funding and focus on EVD research for effective prevention and control.

      A brief historic overview and analysis is presented of the almost 9000 scientific articles that have appeared in the Journal of Inorganic Biochemistry (JIB) and its predecessor (Bioinorganic Chemistry), since 1973. This overview has a focus on the different topics, in particular on the different elements of the Periodic Table and on papers that have received very large numbers of citations. Over the whole period, copper has been the element occurring in most publications (almost 1800, which is 20%), followed by iron which occurs in some 12% of all papers. Other favorite elements are zinc, platinum and ruthenium. The worldwide origin of papers published in JIB has been analyzed as well, showing a quite evenly worldwide distribution, with just a few exceptions. Trends in selected scientific topics over time (first 10 years; last 25 years, last 10 years) are also discussed. Also authors and institutes with the largest number of papers published in JIB have been detected. The numerical information is based on an analysis of the Web of Science with a cutoff date around July 1, 2020.

      Background: The World Health Organization declared the outbreak of COVID-19as a public health emergency of international concern on January 30, 2020. Therefore, relevant research metrics would be an added value for understanding the virus for researchers. Methods: Research outputs related to the Coronavirus were retrieved from the Web of Science database from January 1968 to March 2020 and were analyzed using MS-office, Word Cloud generator, VOS viewer, and ArcGIS software. The analysis was based on the number of research publications per year, contributing author's clustering pattern, most preferred journals, leading publication, document type, broad research areas, commonly used keywords, the geographical distribution of publications, commonly used languages, and productive institutes. Results: The search retrieved 6424 Coronavirus research publications. The number of articles found in the year 1968 was 1, but it was 275 in 2019. A total of 33 clusters of authors contributed to studies on COVID-19 across the globe. The Journal of Virology had the most productivityon Coronavirus publications (n=810). An article published by Ksiazek TG et al in the New England Journal of Medicine had the maximum citation (n=2175); 90% of the research outputs were articles, broadly classified under Infectious diseases (n=5341); and the most commonly used keyword was 'Coronavirus'. The higher number of publications was from the USA (n=2345) and the commonly used language was English (n=5948), and the most productive institute was the University of Hong Kong (n=506). Conclusion: The results of the study showed that the growth pattern was not uniform, the United States, and the University of Hong Kong have played a major role in the contribution of Coronavirus research. Even though this depicts a higher scientific growth, it is an alarming sign to the community for preparedness. Under the prevailing situation of seeking better prevention, treatment and vaccination for COVID-19, in-depth research in the above portrayed metrics would be an added knowledge for the researchers.

      BACKGROUND: Social participation is an indicator of successful ageing and important determinant of health outcomes. As more studies have been conducted on social participation of older people, a comprehensive and quantitative analysis of the current literature will contribute to a better understanding of the main and novel issues and improve existing geriatric care services in this domain. However, limited bibliometric analysis was employed in this research field. Therefore, we conducted this study to investigate the research trend and quantitatively and comprehensively characterise the landscapes of publications on social participation of older people via bibliometric analysis methods.METHODS: Data were obtained from the Web of Science Core Collection in January 2020. CiteSpace 5.5.R2 and VOSviewer software packages were used to generate knowledge maps and analyse the publication outputs, countries/regions, institutions, journals, research hot spots and research frontiers.
    RESULTS: A total of 7,029 publications between 2000 and 2019 were retrieved, and the publication number per year continues to increase. The United States held a leading position in this research field, and Duke University was the most productive institution. Co-cited reference cluster analysis and keyword co-occurrence analysis showed that research hot spots contained factors of healthy ageing, quality of life, psychological problems and health status, especially dementia, function (including cognitive function) and frailty. Burst detection of keywords revealed that social participation, social support, instrumental activity, frailty and loneliness have been new research frontiers since 2015.
    CONCLUSIONS: By analysing publications over the past 20 years, we found publication trends and characteristics in this field. These findings will hopefully provide new insight into the scientific landscapes and further directions in the study of social participation of older people.
    IMPLICATIONS FOR PRACTICE: Social participation is strongly associated with physical and psychological problems and the well-being of older people. Related professionals, such as social workers, psychologists, nurses and many other health care practitioners, should raise widespread awareness and concern over research hot spots and frontiers on this topic to promote research knowledge translation and adoption into the practice of caring for older people.

      OBJECTIVES: The aim of this article is to analyze the development of integrative oncology from a bibliometric point of view. The publication and citation patterns of publications are analyzed and their contents mapped.DESIGN: This study is based on bibliometric methods. The data sets consist of 7 025 respectively 4 990 publications over the time period 1966-2016, shown in PubMed and Web of Science.
    RESULTS: The expansion of the numbers of these publications took place in the late 1990s/early 2000s. Research is dominated by authors located in the USA, China and Germany who are working at well-established research universities and university hospitals. The clinical share of publications is relatively small, and few studies are classified according to clinical phase. Content analysis revealed that much of the clinical research is based on surveys, and that content reflects the intersection of complementary therapies and cancer research. The latter aspect is less obvious in pre-clinical research. The most frequent journals in the material show a focus on complementary and alternative therapies or on integrative oncology, although journals focused on oncology or general/internal medicine were well-represented in the material as a whole. The most-cited publications were review articles and surveys.
    CONCLUSIONS: Integrative oncology has been established as a small, but distinct, research domain. There are several signs of specialization in integrative oncology, but also in its integration into general medical and oncological research.

      Background: Inaccurate citations are erroneous quotations or instances of paraphrasing of previously published material that mislead readers about the claims of the cited source. They are often unaddressed due to underreporting, the inability of peer reviewers and editors to detect them, and editors' reluctance to publish corrections about them. In this paper, we propose a new tool that could be used to tackle their circulation.Methods: We provide a review of available data about inaccurate citations and analytically explore current ways of reporting and dealing with these inaccuracies. Consequently, we make a distinction between publication (i.e., first occurrence) and circulation (i.e., reuse) of inaccurate citations. Sloppy reading of published items, literature ambiguity and insufficient quality control in the editorial process are identified as factors that contribute to the publication of inaccurate citations. However, reiteration or copy-pasting without checking the validity of citations, paralleled with lack of resources/motivation to report/correct inaccurate citations contribute to their circulation.
    Results and discussion: We propose the development of an online annotation tool called "MyCites" as means with which to mark and map inaccurate citations. This tool allows ORCID users to annotate citations and alert authors (of the cited and citing articles) and also editors of journals where inaccurate citations are published. Each marked citation would travel with the digital version of the document (persistent identifiers) and be visible on websites that host peer-reviewed articles (journals' websites, Pubmed, etc.). In the future development of MyCites, challenges such as the conditions of correct/incorrect-ness and parties that should adjudicate that, and, the issue of dealing with incorrect reports need to be addressed.

      Researchers seek to identify optimal journals for submission based on their studies but tend to rely on journal impact factors or scientific journal rankings. We investigated research trends by selecting high-frequency words from author keywords (AKs), analyzing subject areas, and performing quantitative data analysis of Korean dental journals. Consequently, we suggest a method for choosing journals that fit a specific subject area.We used a corpus of 9 Korean dentistry journals regarded in Korea as quality internationally approved journals. AKs occurring more than 10 times were assigned to Medical Subject Headings (MeSH) terms and subcategories, which were then categorized using the MeSH tree structure. KnowledgeMatrix Plus and VOSviewer were used to analyze network relationships, density, and clustering.The AKs were of 7527 types, 15,960 terms, and formed 54 clusters. The AKs with 10+ occurrence were 199 types, 4289 terms, and formed 9 clusters. Assigning the AKs with 10+ occurrence to MeSH terms led to expanding 732 types of AK terms into 249 types with 9 clusters and 4268 links. Core study areas over the past 10 years were facial asymmetry, a topic under oral surgery and medicine, and orthognathic surgery focused on mandibular fractures, followed by shear bond strength of zirconia. Analyzing 16 MeSH subject categories, we found that the "analytical, diagnostic and therapeutic techniques and equipment" category had the largest distribution of AKs (40.7%). This was followed by "diseases" (21.2%) and "anatomy" (14.90%). The orthognathic surgery cluster was the largest, followed by the shear bond strength cluster. Dental implants is a core area with strong links to high-occurrence words, such as cone-beam computed tomography and mandible, which were distributed in the order of The Journal of Advanced Prosthodontics (37.8%) and Journal of Periodontal & Implant Science (30.6%). Five clusters were closely packed in the center, 2 clusters were formed above the center, 1 cluster was formed below the center, and a cluster on the right was widespread.Cluster analysis using AKs and MeSH may be a good analytic method for researchers to determine expanding research areas and select optimal journals for paper submission.

      PURPOSE: The purpose of the current study was to (1) compare the Altmetric Attention Score (AAS) and citation rates between orthopedic and non-orthopedic randomized controlled trials (RCTs) from five high-impact medical journals and (2) identify general characteristics of these articles associated with greater exposure on social media platforms.METHODS: Articles published in The New England Journal of Medicine (NEJM), Lancet, Journal of the American Medical Association (JAMA), Annals of Internal Medicine, and Archives of Internal Medicine between January 2011-December 2016 were analyzed. These journals were selected based on retaining high impact factors with rigorous publication standards and availability of the AAS for their publications. The queried time frame was chosen to balance the inception of the AAS with an optimal period for citation accrual. A total of fourteen article characteristics, in addition to number of Tweets, Facebook shares, news mentions, and the AAS, were extracted. Inclusion criteria was orthopedic RCTs reporting on outcomes following surgical intervention. Linear regressions were used to assess the relationship between publication characteristics and the AAS and social media attention.
    RESULTS: A total of 9 orthopedic and 59 non-orthopedic RCTs were included. The mean AAS were significantly different (574±565.7 vs 256.9±222.3, p=0.003), whereas citation rate was not (192.2±117.1 vs 382.3±560.3, p=0.317). Orthopedic RCTs had a significantly greater number of mentions on Twitter and Facebook (p<0.001). A higher AAS significantly associated with a greater number of citations (β:0.75, p=0.019) for orthopedic RCTs. The mean AAS of orthopedic RCTs favoring non-operative management (809.6±676.3) was greater than those favoring operative treatment (292.0±248.9) but was not statistically significant (p=0.361).
    CONCLUSION: Orthopedic RCTs published in 5 high-impact general medical journals had a significantly greater mean AAS relative to non-orthopedic RCTs with no differences in citation rates. Additionally, there was a strong association between the AAS and citation rate of orthopedic RCTs. Orthopedic RCTs had greater social media exposure on both Twitter and Facebook.
    CLINICAL RELEVANCE: Orthopaedic surgeons, researchers and providers who publish RCTs in high-impact medical journals can anticipate extensive social media attention for their articles relative to other non-orthopaedic RCTs in the same journals. Social media attention may be related to operative versus non-operative management topics. This study provides further evidence for the increasing use of the AAS and its association with citation accrual.

      In recent decades, the volume of scholarly literature worldwide has increased significantly, and open-access publishing has become commonplace. These changes are even more dominant in South Korea. Comparing the periods of 1981-2000 and 2001-2020, the number of medical articles produced in Korea increased by 16.8 times on the Web of Science platform (13,223 to 222,771 papers). Before 1990, almost no open-access articles were produced in South Korea, but in the last 10 years open-access publications came to account for almost 40% of all South Korean publications on Web of Science. Along with the expansion of literature and the development of open-access publishing, predatory journals that seek profit without conducting quality assurance have appeared and undermined the academic corpus. In this rapidly changing environment, medical researchers have begun contemplating publication standards. In this article, recent trends in academic publishing are examined from international and South Korean perspectives, and the significance of open-access publishing and recent changes are discussed. Practical methods that can be used to select legitimate publishers, including open-access journals, and identify predatory journals are also discussed.

      A systematic literature review was conducted to describe in a historical perspective the evolution of studies concerning HPV vaccination. The search identified 794 articles of which 568 were included. The first article was published in 2001, and the maximum annual number of publications was reached in 2014. The average number of authors per paper was 8.8. Papers originated from 49 different countries, with the USA accounted for the maximum number of publications (n = 217). Efficacy (46.5%) and safety (31.0%) were the most prevalent objectives. Clinical trials constituted the largest group of methods (37.9%). Chronological trends did not reveal any lasting curve-crossings, indicating that the priority topics have remained the same. The geographical origin of these studies raises questions about the transposability of the results to populations where HPV vaccination has been studied only a little. This study could help guide future research to less-studied research objectives, particularly for vaccines.

      Background: Research is a cornerstone for the advancement of clinical practice and guidelines across all medical and surgical fields. To achieve significant contribution to the field, research must be circulated, read, and understood.Purpose: The purpose of this paper is to investigate which factors are associated with higher and lower citation rates in orthopaedic surgery literature.
    Methods: A query was performed to identify all of the primary research articles published between 1998 and 2008 in four prominent orthopaedics journals. From there, the 50 most highly and lowly cited articles were identified and analyzed for various factors that distinguished the highly cited group from the lowly cited group. Various statistical tests were used depending on the type of variable being evaluated.
    Results: After data compilation and statistical analysis, 16 statistically significant factors were apparent that differed between the two groups. Seven non-statistically significant factors were also identified.
    Conclusion: This study illustrates that certain statistically significant factors influence the citation rates of papers in orthopaedic surgery literature. If utilized appropriately, these factors could lead to increased consumption and circulation of future orthopaedic surgery literature.

  18. Urology. 2020 Sep 20. pii: S0090-4295(20)31148-1. [Epub ahead of print]
      OBJECTIVE: To describe the proportions of peer-reviewed manuscripts authored by women in five high-impact, widely available urology journals, and to compare these to the proportion of women in urology. About 9% of attending urologists and 25% of urology residents are women. We hypothesized that women comprised fewer than 25% of first authors and fewer than 10% of last/senior authors.METHODS: We searched peer-reviewed original manuscripts in the Journal of Urology, Journal of Pediatric Urology, Neurourology and Urodynamics, Urology, and Urologic Oncology from January 2014 to June 2019. First and last author gender identity was recorded. Observed and expected proportions and temporal trends were compared, with findings considered statistically significant at p<0.05.
    RESULTS: Of 8653 multiple-author papers, 2275 (26.3%) had women as first authors, paralleling the current proportion of women in training (p=0.98). Women were senior/last authors in 1255 (14.5%) papers; this was higher than the current proportion of female urologists in practice (p<0.0001) for all journals but NAU (p=0.59). Only 527 (6.1%) of multiple-author papers had both female first and last authors whereas 5640 (65.3%) of papers had both male first and last authors. The first author was more likely female when the senior author was female (OR=2.34, 95% CI: 2.06-2.65); most female-first and -last authored manuscripts were published in subspecialty journals and those utilizing double-blind peer review.
    CONCLUSIONS: The proportion of female first- and senior-authored manuscripts is significantly higher than the proportion of women in urology, and may reflect differential subspecialty choices and mentorship opportunities for women.

      BACKGROUND: The reference list is an important part of academic manuscripts. The goal of this study is to evaluate the reference accuracy in the field of neurosurgery.METHODS: This study examines four major peer-reviewed neurosurgery journals, chosen based on their clinical impact factor: Neurosurgery, J Neurosurg, World Neurosurg, and Acta Neurochir. For each of the four journals, five articles from each of the journal's 12 issues published in 2019 were randomly selected using an online generator. This resulted in a total of 240 articles, 60 from each journal. Additionally, from each article's list of references, one reference was again randomly selected and checked for a citation or quotation error. The chi-square test was used to analyze the association between the occurrence of citation and quotation errors and the presence of hypothesized risk factors that could impact reference accuracy.
    RESULTS: 62.1% of articles had a minor citation error, 8.33% had a major citation error, 12.1% had a minor quotation error, and 5.8% of articles had a major quotation error. Overall, Acta Neurochir presented with the fewest quotation errors compared with the other journals evaluated. The only association between the frequency of errors and potential markers of reference mistakes was with the length of the bibliography. Surprisingly, this correlation indicated that the articles with longer reference lists had fewer citation errors (p < 0.01). Statistical significance was found between the occurrence of citation errors and the journals of publication (p < 0.01).
    CONCLUSIONS: In order to advance medical treatment and patient care in neurosurgery, detailed documentation and attention to detail are necessary. The results from this analysis illustrate that improved reference accuracy is required.

      Context: The misrepresentation and distortion of research findings, known as "spin," has been shown to affect clinical decision making. Spin has been found in randomized controlled trials (RCTs) published in various fields of medicine.Objective: To evaluate the abstracts of RCTs found in the cardiology literature for spin.
    Methods: The authors searched PubMed using a specific string of keywords to identify previously published articles documenting RCTs of cardiovascular treatments in humans. To be included, a cardiology trial had to randomize humans to an intervention, statistically compare 2 or more groups, and have a nonsignificant primary endpoint. Records were excluded if they did not meet these criteria. Data extraction was double-blinded and done using a pilot-tested Google Form. Items extracted from each trial included the title, journal, funding source, comparator arm, primary endpoint, statistical analysis of the primary endpoint, secondary endpoints, statistical analysis of secondary endpoints, and trial registration number (if reported). The 2 authors who screened records for inclusion were then asked whether spin was present in the abstract of the randomized trial. Spin in the title, abstract results, abstract conclusions, and selection of reported endpoints were considered.
    Results: Of the 651 PubMed citations retrieved by our search string, 194 RCTs with a clearly defined primary endpoint were identified. Of these 194 RCTs, 66 trials contained nonsignificant primary endpoints and were evaluated for spin. Of these trials, spin was identified in 18 of the 66 abstracts (27.3%).
    Conclusions: Spin was present in our sample of cardiology RCTs. Spin may influence clinical decision making by creating false impressions of the true validity of a drug or intervention.

      Research on health inequalities and health disparities has grown exponentially since the 1960s, but this expansion has not been matched by an associated sense of progress. Criticisms include claims that too much research addresses well-trodden questions and that the field has failed to gain public and policy traction. Qualitative studies have found researchers partly attribute these challenges to fragmentation resulting from disciplinary and methodological differences. Yet, empirical investigation ('research on research') is limited. This study addresses this gap, employing mixed-methods to examine, at scale, how and why this field is defined by insular research clusters. First, bibliometric analysis identifies and visualizes the 250 most-connected authors. Next, an algorithm was used to identify clustering via citation links between authors. We used researcher profiling to ascertain authors' geographical and institutional locations and disciplinary training, examining how this mapped onto clusters. Finally, causes of siloing were investigated via semi-structured interviews with 45 researchers. The resulting 'atlas' of health inequalities and health disparities research identifies eight clusters of authors with varying degrees of connectedness. No single factor neatly describes observed fragmentation, health equity scholars exhibit a diverse disciplinary backgrounds, and geographical, institutional, and historical factors appear to intersect to explain siloed citation patterns. While the configuration of research activity within clusters potentially helps render questions scientifically manageable, it affirms perceptions of the field as fragmented. We draw on Thomas Kuhn and Sheila Jasanoff to position results within theoretical pictures of scientific progress. Newcomers to the field can use our findings to orient themselves within the many streams of health equity scholarship, and existing health equity scholars can use the atlas to move beyond existing geo-disciplinary networks. However, although stronger cross-cluster engagement would be likely to improve insights, the complex nexus of factors underlying the field's structure will likely make this challenging in practice.

      OBJECTIVE: To evaluate whether a financial incentive changed research patterns among residents over a 12-year period.METHODS: At our institution, beginning July 2016, any resident work that led to a PubMed citation was awarded $1,000. A review of the PubMed database and the regional meeting of the South Central Section of AUA (SCS/AUA) presentation itineraries were used to quantify and qualify the participation in research by these residents before and after introduction of the financial incentive.
    RESULTS: Scholarly activity from thirty out of thirty possible residents was evaluated. The monetary incentive resulted in increased production post-incentive (6.33) vs. pre-incentive (2.44) in average total authorship participation published to PubMed per year (p=0.0125). The average number of PubMed primary authorships per year for the entire residency program increased from 0 in July 2007-June 2008 to 0.7 in July 2018-June 2019, displaying upward trajectory. Average primary authorship of research produced per year presented at SCS/AUA and published to PubMed increased post-incentive (9.00) vs. pre-incentive (4.89) (p=0.0479). More review articles and less basic science research were published after the incentive.
    CONCLUSION: Offering financial incentives to urology residents increased publications and meaningful participation in research.

      BACKGROUND AND PURPOSE: Gender bias is a known issue in healthcare and academia. We analysed the gender of patients reported in the literature with "man-in-the-barrel syndrome" or equivalent semiological terms.METHODS: A search in PubMed database was conducted using the terms "man-in-the-barrel", "person-in-the-barrel", "woman-in-the-barrel", "brachial diplegia", "flail arm" and "cruciate paralysis". All articles published between 1969 and 2020 containing a detailed description compatible with the original description of "man-in-the-barrel syndrome" were included.
    RESULTS: Ninety-five patients with a clinical picture compatible with "man-in-the-barrel syndrome" were included. Up to 33% of patients were female. Overall, the proportion of female patients with "man-in-the-barrel syndrome" was 25%.
    DISCUSSION AND CONCLUSIONS: The term "man-in-the-barrel" may disenfranchise up to a third of women presenting with brachial diplegia with undesirable consequences. We propose a gender-neutral alternative such as "person-in-the-barrel".

      Obstructive Sleep Apnea is emerging as a global health epidemic, particularly due to the obesity pandemic. However, comprehensive prevalence data are still lacking and global OSA research has not yet been structurally evaluated. Using the latest comprehensive age/gender-specific BMI and obesity data, a global landscape estimating the risk/burden of OSA was created. Results were presented in relation to an in-depth analysis of OSA research and countries' socioeconomic/scientific background. While the USA, Canada, and Japan are the highest publishing countries on OSA, Iceland, Greece, and Israel appeared at the forefront when relating the scientific output to socioeconomic parameters. Conversely, China, India, and Russia showed relatively low performances in these relations. Analysis of the estimated population at risk (EPR) of OSA showed the USA, China, India, and Brazil as the leading countries. Although the EPR and OSA research correlated strongly, major regional discrepancies between the estimated demand and actual research performances were identified, mainly in, but not limited to, developing nations. Our study highlights regional challenges/imbalances in the global activity on OSA and allows targeted measures to mitigate the burden of undiagnosed/untreated OSA. Furthermore, the inclusion of disadvantaged countries in international collaborations could stimulate local research efforts and provide valuable insights into the regional epidemiology of OSA.

      OBJECTIVE: The references list is an important part of a scientific article that serves to confirm the accuracy of the authors' statements. The goal of this study was to evaluate the reference accuracy in the field of spine surgery.METHODS: Four major peer-reviewed spine surgery journals were chosen for this study based on their subspecialty clinical impact factors. Sixty articles per journal were selected from 12 issues each of The Spine Journal, Spine, and Journal of Neurosurgery: Spine, and 40 articles were selected from 8 issues of Global Spine Journal, for a total of 220 articles. All the articles were published in 2019 and were selected using computer-generated numbers. From the references list of each article, one reference was again selected by using a computer-generated number and then checked for citation or quotation errors.
    RESULTS: The results indicate that 84.1% of articles have a minor citation error, 4.5% of articles have a major citation error, 9.5% of articles have a minor quotation error, and 9.1% of articles have a major quotation error. Journal of Neurosurgery: Spine had the fewest citation errors compared with the other journals evaluated in this study. Using chi-square analysis, no association was determined between the occurrence of errors and potential markers of reference mistakes. Still, statistical significance was found between the occurrence of citation errors and the spine journals tested.
    CONCLUSIONS: In order to advance medical treatment and patient care in spine surgery, detailed documentation and attention to detail are necessary. The results from this study illustrate that improved reference accuracy is required.

      Purpose: This study's primary objective is to evaluate the time spent in the peer-review process for orthopaedic publications related to the Covid-19 pandemic. The secondary objective is to evaluate the countries' and journals' contributions in these publications.Materials and methods: We carried a search on August 1st, 2020, in one database (PubMed) using limited search terms to identify the orthopaedic publications related to the Covid-19 pandemic. After a filtration process, we evaluated the eligible article to identify the prevalence of different articles types, different countries, and journal contributions in these publications. The evaluation of the time spent in the peer-review process was done by obtaining the submission and acceptance dates.
    Results: Of the 231 articles eligible for initial assessment, review articles were the most common article type published (51%), 48 countries published articles in a unique 78 journals. Evaluation of the peer-review process in 147 articles revealed that the mean time from submission to acceptance was 14.3 ± 15.8 days (range from 0 to 74), the peer-review process took less than 30 days in 127 (86.4%) articles, 15 (10.2%) articles were accepted within the first day of submission.
    Conclusion: Orthopaedic community contributed significantly to the publications related to the Covid-19 pandemic, with a contribution from many countries and journals. The peer-review process was notably shortened for some articles.

      Translational medicine is a branch of medical research that attempts to establish a more direct link between basic research and clinical practice. The improvement of clinical management cannot be separated from the progress and breakthrough made in basic biomedical research. As one of the main funding agencies for basic research in China, National Natural Scientific Foundation of China (NSFC) plays an active role in promotion of the development of basic medical research and translational medicine. General Program mainly supports scientists to carry out basic research on bottom-up based topics within the funding scope of NSFC to conduct innovative research and promote a balanced, coordinated and sustained development of all disciplines. Musculoskeletal injury and disease is a major threat to human health worldwide and has become the major cause of disability in China. In this review, we aim to further promote the clinical transformation by summarizing the trends and hotspots of basic research in this field based on the analysis of the data of General Program in abnormalities and diseases of locomotor system over the last decade, including analyses of the number of applications received and projects funded, the distribution of the keywords in applications and grants, distribution of applications and grants of General Program in the secondary application code of H06 and in the host institution.

      Engagement with scientific manuscripts is frequently facilitated by Twitter and other social media platforms. As such, the demographics of a paper's social media audience provide a wealth of information about how scholarly research is transmitted, consumed, and interpreted by online communities. By paying attention to public perceptions of their publications, scientists can learn whether their research is stimulating positive scholarly and public thought. They can also become aware of potentially negative patterns of interest from groups that misinterpret their work in harmful ways, either willfully or unintentionally, and devise strategies for altering their messaging to mitigate these impacts. In this study, we collected 331,696 Twitter posts referencing 1,800 highly tweeted bioRxiv preprints and leveraged topic modeling to infer the characteristics of various communities engaging with each preprint on Twitter. We agnostically learned the characteristics of these audience sectors from keywords each user's followers provide in their Twitter biographies. We estimate that 96% of the preprints analyzed are dominated by academic audiences on Twitter, suggesting that social media attention does not always correspond to greater public exposure. We further demonstrate how our audience segmentation method can quantify the level of interest from nonspecialist audience sectors such as mental health advocates, dog lovers, video game developers, vegans, bitcoin investors, conspiracy theorists, journalists, religious groups, and political constituencies. Surprisingly, we also found that 10% of the preprints analyzed have sizable (>5%) audience sectors that are associated with right-wing white nationalist communities. Although none of these preprints appear to intentionally espouse any right-wing extremist messages, cases exist in which extremist appropriation comprises more than 50% of the tweets referencing a given preprint. These results present unique opportunities for improving and contextualizing the public discourse surrounding scientific research.

      AIM: This research aims to present a general summary of researches on workplace incivility in nursing using bibliometric indicators.BACKGROUND: Nurses regularly experience incivility from their working environment. However, evidence shows that it has significant potential for harmful consequences, both in terms of their health and productivity. Therefore, nursing and hospital managers have a crucial role in creation and maintenance of civil behavior.
    METHOD(S): This research reports on a bibliometric analysis using a systematic review of academic literature on workplace incivility in nursing. A search of Web of Science databases was performed and a total of 269 abstracts were investigated. Calculation of bibliometric indicator was done in Excel and tag clouds had been created in Vosviewer.
    RESULTS: Nursing incivility literature is growing, and the USA contributed the largest number of papers. Studies have been carried out on nurses working in hospitals and nursing students in general. Topics are mainly focused on the organizational consequences of uncivil behavior, CONCLUSION(S): This study reveals that there are not enough studies on workplace incivility in nursing.
    IMPLICATIONS FOR NURSING MANAGEMENT: As a results obtained from this research, it especially recommends healthcare and nursing managers to research some risky groups and subject less studied yet.

  32. J Oral Maxillofac Surg. 2020 Aug 28. pii: S0278-2391(20)31097-1. [Epub ahead of print]
      PURPOSE: Journal articles in our field of oral and maxillofacial surgery are rife with case studies, cohort reviews, meta-analysis, basic science studies, surgical techniques, and anatomic studies. The data found in these studies often rely on multiple measurements by which the authors draw their conclusions. Accurate measurements play a critical role in the design of the study, which in turn affects the conclusion that the author is attempting to convey. Investigators must determine and develop the processes to determine the methodological errors associated with each project to help with determining the accuracy of these measurements. The aim of this study is to highlight some of the methodological errors contained in the material and methods in oral and maxillofacial surgery studies over the calendar years of 2018 and 2019 and how best to evaluate them.MATERIALS AND METHODS: The inclusion criteria involved articles that used measurements where discrepancies could exist such as clinical measurements, histological measurements, and radiological measurements. The number of specimens or subjects measured in each study was tabulated.
    RESULTS: Over the 2-year period considered, 744 articles were published, and 116 (15.6%) of them met the inclusion criteria. Of these articles, 37 (32%) reported a methodological error, while 79 (68%) did not. In addition, 31 (84%) of the articles with a methodological error were radiographic, while only 6 (16%) were not radiographic. Among the studies that reported methodological error, there were approximately seven different types used with no rationale given for the choice.
    CONCLUSIONS: We believe that it is important to ensure sound methods and materials, including a stated methodological error. An attempt at standardization will help to serve to enhance and strengthen the different research studies seen in our field.

      Academics, policymakers, and practitioners have long considered peace and sustainability to be fundamentally linked. However, despite the increased attention paid toward the intersection of peace and sustainability, there is still limited knowledge on the nature of their linkages. To advance the current understanding on the peace-sustainability nexus and inform an integrated research agenda, this paper employs a scientometric analysis of literature to identify publication trends, thematic clusters, and knowledge gaps. Analyzing the publications according to the types of peace, the pillars of positive peace, the dimensions of sustainability, and the SDGs further reveals weak engagement among academic disciplines and across the SDGs. The results of this analysis emphasize the need for future research to focus on underexamined subjects, geographic regions, and sectors to bolster the linkages between peace and sustainability.
