The influence of social media mentions on Foot and Ankle Orthopaedic literature has not yet been investigated. The primary purpose of this study is to identify the social media outlets that were most associated with the Altmetric attention score (AAS). The secondary aim is to characterize the top 100 most highly cited articles within Foot and Ankle literature with the top 100 scoring Altmetric articles. Methods: We conducted a query of the Altmetric database for all journal titles containing the words ‘Foot’ and ‘Ankle.’ In accordance with other investigations, articles were only included after 2010, since this was beginning of academic social media participation. We assessed the frequency and percent of articles by journal, collecting variables including impact factor, AAS, along with average mentions within news, blogs, policy, patents, Twitter, peer review, Weibo, Facebook, Wikipedia, Google+, LinkedIn, Reddit, Pinterest, F1000, Q&A, online video, Syllabi, and traditional metrics such as number of Mendeley readers and citations (Table 1). We used a Spearman, semi-partial, and partial correlation test to detect the association between AAS and media outlet mentions, Mendeley readers or Dimensions citations. Finally, we ranked one article list with the 100 most popular articles on social media and one with the 100 most cited articles. Articles were examined for overlap, topic, article type, and level of evidence. Results: Our search returned 4,365 articles. Foot and Ankle International had the highest frequency of articles, though the Journal of Foot and Ankle Research had the highest AAS (Table 1). News and Twitter mentions had the greatest association with AAS. The top study designs for the AAS articles were prospective (n=35), retrospective (n=25), and systematic reviews (n=17), compared to the most highly cited articles which had retrospective (n=32), review (n=31), and observational studies (n=26) (p<0.001). When examining the top 100 highest AAS scoring articles with the 100 most cited, there was only one article in both groups. Compared to the most highly cited articles, the highest ranked AAS articles had a better average level of evidence (Cited: 3.4 vs. AAS: 2.9, p=0.001). Conclusion: Twitter and mentions within news are the most correlated with AAS. Although traditional metrics for article influence often reference an article’s citation count, attaining social media relevance is becoming more important than before. There is currently very little overlap among the most highly cited and the most mentioned articles on social media. Future research is needed to address whether citation counts or social media presence have more influence on actual clinical practice. [Table: see text]

Purpose The purpose of this paper is to study the presence of highly cited papers of Nature in social media websites and tools. It also tries to examine the correlation between altmetric and bibliometric indicators. Design/methodology/approach This descriptive study was carried out using altmetric indicators. The research sample consisted of 1,000 most-cited articles in Nature. In February 2019, the bibliographic information of these articles was extracted from the Scopus database. Then, the titles of all articles were manually searched on Google, and by referring to the article in the journal website and altmetric institution, the data related to social media presence and altmetric score of articles were collected. The data were analyzed using Microsoft Excel and SPSS. Findings According to the results of the study, from 1,000 articles, 989 of them (98.9 per cent) were mentioned at least once in different social media websites and tools. The most used altmetric source in highly cited articles was Mendeley (98.9 per cent), followed by Citeulike (79.8 per cent) and Wikipedia (69.4 per cent). Most Tweets, blog posts, Facebook posts, news stories, readers in Mendeley, Citeulike and Connotea and Wikipedia citations belonged to the article titled “Mastering the game of Go with deep neural networks and tree search”. The highest altmetric score was 3,135 which belonged to this paper. Most tweeters and articles’ readers were from the USA. The membership type of the tweeters was public membership. In terms of fields of study, most readers were PhD students in Agricultural and Biological Sciences. Finally, the results of Spearman’s Correlation revealed positive significant statistical correlation between all altmetric indicators and received citations of highly cited articles (p-value = 0.0001). Practical implications The results of this study can help researchers, editors and editorial boards of journals better understand the importance and benefits of using social media and tools to publish articles. Originality/value Altmetrics is a relatively new field, and in particular, there are not many studies related to the presence of articles in various social media until now. Accordingly, in this study, a comprehensive altmetric analysis was carried out on 1000 most-cited articles of one of the world's most reliable journals.

IntroductionCitation counts of articles have been used to measure scientific outcomes and assess suitability for grant applications. However, citation counts are not without limitations. With the rise of social media, altmetric scores may provide an alternative assessment tool.ObjectivesThe aims of the study were to assess the characteristics of highly cited articles in medical professionalism and their altmetric scores.MethodsThe Web of Science was searched for top-cited articles in medical professionalism, and the characteristics of each article were identified. The altmetric database was searched to identify report for each identified article. A model to assess the relationship between the number of citations and each of the key characteristics as well as altmetric scores was developed.ResultsNo correlations were found between the number of citations and number of years since publication (p=0.192), number of institutes (p=0.081), number of authors (p=0.270), females in authorship (p=0.150) or number of grants (p=0.384). The altmetric scores varied from 0 to 155, total=806, median=5.0, (IQR=20). Twitter (54%) and Mendeley (62%) were the most popular altmetric resources. No correlation was found between the number of citations and the altmetric scores (p=0.661). However, a correlation was found for articles published in 2007 and after (n=17, p=0.023). To further assess these variables, a model was developed using multivariate analysis; did not show significant differences across subgroups. The topics covered were learning and teaching professionalism, curriculum issues, professional and unprofessional behaviour.ConclusionsAltmetric scores of articles were significantly correlated with citations counts for articles published in 2007 and after. Highly cited articles were produced mainly by the USA, Canada and the UK. The study reflects the emerging role of social media in research dissemination. Future studies should investigate the specific features of highly cited articles and factors reinforcing distribution of research data among scholars and non-scholars.

Category: Other Introduction/Purpose: As the field of foot and ankle surgery grows and new innovations continue to be made it is important that the quality of research improves. This will help to lay a strong foundation for current and future surgeons in the field. Leading journals need to set the tone for all orthopedic journals by publishing quality literature. This current study will look at all foot and ankle articles published by JBJS[A] over a 15-year period and analyze authorship, article type, geographic origin of articles, and level of evidence trends. This study will give a representative view of where foot and ankle research is currently and where it can go as we enter the new decade. Methods: A foot and ankle research fellow reviewed all of the articles published in JBJS[A] from January 2004 to December of 2018. Articles that related to foot and ankle topics were then selected to analyzed. Editorials, letters to the editor, announcements, technical notes, retraction notes, events, errata, retracted manuscripts, historical papers and pediatric foot and ankle articles were excluded. After exclusions were applied 321 and information pertaining to each article was analyzed. Additionally, a Google Scholar search was conducted for each article to determine the number of times an article had been cited. For calculations relating to median number of citations for each article we excluded articles that were published less than three years ago (2017 and 2018). For level of evidence a kappa value (0.82) was calculated to measure interobserver reliability between two reviewers. Results: We found the following results to be significant. Clinical therapeutic studies were the predominant study design over 15 years. The amount of literature over ankle arthroplasty has increased more than any other article topic. The amount of level IV and V evidence has decreased and the amount of level II and III evidence has increased. The median number of authors has been increasing. This includes female authorship. There has been in an increase in MD, PhDs as last authors. There is more foot and ankle research being produced by Asian countries. A majority of high level of evidence articles (level I and II) comes from North America and Europe. Level of evidence doesn’t correlate with the amount of times an article is cited. Conclusion: As the field of foot and ankle surgery continues to grow it is important that there is a high quality of research being conducted and published to guide surgical and clinical decisions. Our study shows that research is being produced more globally and the number of individuals involved in the research process is increasing and diversifying. This has led to higher quality research being produced (more level II and III) and a decrease in lower quality research (IV and V). Overall, the standard of research has increased in JBJS[A] which benefits the foot and ankle surgery community. [Table: see text]

Background: The quality of research and evidence to support medical treatments is under scrutiny from the medical profession and the public. This study examined the current quality of research and level of evidence (LOE) of foot and ankle surgery papers published in orthopedic and podiatric medical journals. Methods: Two independent evaluators performed a blinded assessment of all foot and ankle clinical research articles (January 2010 to June 2010) from seven North American orthopedic and podiatric journals. JBJS-A grading system was used for LOE. Articles were assessed for indicators of study quality. The data was stratified by journal and medical credentials. Results: A total of 245 articles were published, 128 were excluded based on study design, leaving 117 clinical research articles. Seven (6%) were Level I, 14 (12%) Level II, 18 (15%) Level III, and 78 (67%) Level IV. The orthopedic journals published 78 studies on foot and ankle topics. Of the podiatric journals, the Journal of the American Podiatric Medical Association (JAPMA) published 12 clinical studies and the Journal of Foot and Ankle Surgery (JFAS) published 27, 21 (78%) of which were Level IV studies. When the quality of research was examined, few therapeutic studies used validated outcome measures and only 38 of 96 (40%) gathered data prospectively. Thirty (31%) studies used a comparison group. Eighty-seven articles (74%) were authored by a MD and 22 (19%) by a DPM. Conclusion: Foot & Ankle International (FAI) published higher quality studies with a higher LOE as compared to podiatry journals. Regardless of the journal, MDs produced the majority of published clinical foot and ankle research. Although improvements have been made in the quality of some clinical research, this study highlights the need for continued improvement in methodology within foot and ankle literature.

AbstractBibliometric analysis is a statistical method that attempts to assess articles by their citations, analyzing their frequency and citation pattern, which subsequently gleans direction and guidance for future research. Over the past few years, articles focused on intrauterine adhesions have been published with increasing frequency. Nevertheless, little is known about the properties and qualities of this research, and no current analysis exists that has examined the progress in intrauterine adhesion research. Web of Science Core Collection, BIOSIS Citation Index, and MEDLINE database were searched to identify articles on intrauterine adhesion published from 1950 to October 2020. The 100 most cited articles were chosen to analyze citation count, citation density, authorship, theme, geographic distribution, time-related flux, level of evidence, and network analysis. An overwhelming majority of these 100 articles were published in the 2010s (35%). Citations per article ranged from 30 to 253. Chinese authors published the most papers in the top 100, followed by the USA, France, Israel, and Italy. The most salient study themes included operative hysteroscopy and adjunctive treatments for improving reproductive outcomes. The most common level of evidence was level II, and there was no statistical difference in the number of citations between the levels. The network analysis indicated that hysteroscopy, hysteroscopic adhesiolysis, infertility, and the reproductive outcome had a great degree of centrality in the 2000s and 2010s. In comparison, placental implantation had a great degree of centrality in the 2000s, and stem cell and fibrosis had a great degree of centrality in the 2010s. The value of IUA investigation has been gradually appreciated recently. Hysteroscopic adhesiolysis was continuously explored to achieve better reproductive outcome. Over time, the main focus of research has gradually shifted from complications to postoperative adjuvant treatment. Moreover, breakthrough progress is needed in underlying mechanism and early prevention of IUA.

Abstract Although many reviews describe significant advances in burn care, no studies have yet examined why these papers had such profound impact. Our objective was to identify the most highly cited, as well as the most clinically influential studies in burns, and describe their characteristics, to inform future research in the field. Web of Science was searched using keywords related to burns to identify the 100 most-cited burns papers. Study design, year and journal of publication, and subject of the paper were recorded. A mixed-methods approach was used to identify papers in burn research leading to change in clinical practice. Characteristics of these papers were compared with identify any factors predictive of future citations or clinical influence. The 100 highly cited papers were cited between 159 and 907 times. There was no correlation between total citations and journal impact factor, year of publication, or subject area. Level of evidence did not predict future citations or influence, but may be influenced by evolving research standards. Of 23 clinically influential studies, 6 were not among 100 most-cited. Using papers only from the 100 most-cited list was not sufficient to identify leading researchers in burns. Citation analysis is a beneficial, however not alone sufficient to identify landmark papers, particularly for multidisciplinary fields such as burns.

Objective – To determine whether the use of PubMed methods-based filters and topic-based filters, alone or in combination, improves physician searching. Design – Mixed methods, survey questionnaire, comparative. Setting – Canada. Subjects – Random sample of Canadian nephrologists (n=153), responses (n=115), excluded (n=15), total (n=100). Methods – The methods are described in detail in a previously published study protocol by a subset of the authors (Shariff et al., 2010). One hundred systematic reviews on renal therapy were identified using the EvidenceUpdates service (http://plus.mcmaster.ca/EvidenceUpdates) and a clinical question was derived from each review. Randomly-selected Canadian nephrologists were randomly assigned a unique clinical question derived from the reviews and asked, by survey, to provide the search query they would use to search PubMed. The survey was administered until one valid search query for each of the one hundred questions was received. The physician search was re-executed and compared to searches where either or both methods-based and topic-based filters were applied. Nine searches for each question were conducted: the original physician search, a broad and narrow form of the clinical queries therapy filter, a broad and narrow form of the nephrology topic filter and combinations of broad and narrow forms of both filters. Significance tests of comprehensiveness (proportion of relevant articles found) and efficiency (ratio of relevant to non-relevant articles) of the filtered and unfiltered searches were conducted. The primary studies included in the systematic reviews were set as the reference standard for relevant articles. As physicians indicated they did not scan beyond two pages of default PubMed results, primary analysis was also repeated on search results restricted to the first 40 records. The ability of the filters to retrieve highly-relevant or highly-cited articles was also tested, with an article being considered highly-relevant if referenced by UpToDate and highly-cited if its citation count was greater than the median citation count of all relevant articles for that question – there was an average of eight highly-cited articles per question. To reduce the risk of type I error, the conservative method of Bonferroni was applied so that tests with a p less than 0.003 were interpreted as statistically significant. Main Results – Response rate 75%. Physician-provided search terms retrieved 46% of relevant articles and a ratio of relevant to non-relevant articles of 1:16 (p less than 0.003). Applying the narrow forms of both the nephrology and clinical queries filters together produced the greatest overall improvement, with efficiency improving by 16% and comprehensiveness remaining unchanged. Applying a narrow form of the clinical queries filter increased efficiency by 17% (p less than 0.003) but decreased comprehensiveness by 8% (p less than 0.003). No combination of search filters produced improvements in both comprehensiveness and efficiency. When results were restricted to the first 40 citations, the use of the narrow form of the clinical queries filter alone improved overall search performance – comprehensiveness improved from 13% to 26 % and efficiency from 5.5% to 23%. For highly-cited or highly-relevant articles the combined use of the narrow forms of both filters produced the greatest overall improvement in efficiency but no significant change in comprehensiveness. Conclusion – The use of PubMed search filters improves the efficiency of physician searches and saves time and frustration. Applying clinical filters for quick clinical searches can significantly improve the efficiency of physician searching. Improved search performance has the potential to enhance the transfer of research into practice and improve patient care.

Category: Other Introduction/Purpose: As the movement towards evidence-based medicine grows and publication rates rise each year, critical analysis of the orthopaedic literature has become increasingly important. To aid readers in assessing the scientific quality of published research, Foot and Ankle International (FAI) began assigning levels of evidence to all clinical articles in 2008. The purpose of this study was to analyze trends in the characteristics and levels of evidence of articles published in FAI between 2000 and 2015. Methods: All articles published in FAI from 2000, 2005, 2010, and 2015 were reviewed and categorized into article type (clinical, basic science, review, or technical tip). Each clinical article was assigned a level of evidence (I-V) and study type (prognostic, therapeutic, economic, or diagnostic). Descriptive information was gathered pertaining to: country of origin, authorship, and funding. Statistical analysis was performed using chi-squared tests to detect any trends in levels of evidence and publication characteristics. Results: 647 articles were reviewed from 2000 to 2015. There was a statistically significant increase in the publication of clinical articles (70% to 83%; p=0.013). The publication of levels I and II evidence significantly increased (2.44% to 13.53%; p=0.002). Although levels III-V evidence also increased (65% to 70.6%, p=1.014), this was not statistically significant. Publications originated from 39 countries, with a significant increase in the proportion of international papers (32.8% to 48%%; p=0.007). The proportion of articles authored by Podiatrists during the study period significantly decreased (3.73% to 1.74%, p=0.035). Finally, there was an increase in funding disclosures during the study period; funding from grants or professional groups rose from 2.44% to 15.9% (p<0.001) and reported funding from commercial sources rose from 0% to 9.41% (p=0.002). Conclusion: The proportion of level I and II studies published in FAI significantly increased from 2000 to 2015. The publication of clinical research rose, with a majority being therapeutic studies. There was a significant increase in articles published by international authors and a significant decrease in articles published by DPMs. During the same time period, there was a rise in the proportion of articles reporting the use of outside funding, both professional and commercial.

BACKGROUND Citation counts of articles have been used by universities and funding bodies to measure scientific outcomes and assess suitability for grant applications. However, citation counts are not without limitations. With the rise of social media, altmetric scores may provide an alternative assessment tool. OBJECTIVE The aims of this study are to assess the characteristics of highly cited articles in medical professionalism and their altmetric scores. METHODS The Web of Science was searched for top-cited articles in medical professionalism, and the characteristics of each article were identified. The altmetric database was searched to identify report for each identified article. A model to assess the relationship between the number of citations and each of key characteristics as well as altmetric scores was developed. RESULTS No correlations were found between the number of citations and number of years since publication (p=0.192), number of institutes (p=0.081), number of authors (p=0.270), females in authorship (p=0.15), or number of grants (p=0.384). The altmetric scores varied from zero to 155, total= 806, median=5.0, (IQR=20). Twitter (54%) and Mendeley (62%) were the most popular altmetric resources. No correlation was found between the number of citations and the altmetric scores (p=0.661). To further assess these variables a model was developed using multivariate analysis; did not show significant differences across subgroups. The topics covered were learning and teaching professionalism, curriculum issues, professional and unprofessional behavior, defining and measuring professionalism. The articles were mainly published in Academic Medicine, Journal of the American Medical Association, Journal of General Internal Medicine, and Annals of Internal Medicine. CONCLUSIONS No correlation was found between citations and any of the article parameters. Altmetric scores of articles were not significantly correlated with citations. Highly cited articles were produced mainly by the United States, Canada, and the United Kingdom. The study reflects the emerging role of altmetric and social media in the dissemination of research. Future studies should investigate the specific features of highly cited articles and factors that reinforce distribution of research data among scholars and non-scholars.
