The online attention analysis on orthognathic surgery research.

OBJECTIVES: Altmetrics is one of the fields of bibliometrics that seeks to assess the impact and interest of a given subject through Internet users. The aim of this study is to make an altmetric analysis of the orthognathic surgery literature. METHODS: A literature search was conducted using Dimensions app up to December 2023. A list of the 100 most mentioned articles on the topic was compiled. A Google Trends search was performed with same strategy to visualize important data regarding internet search. Charts and tables were created using Microsoft Excel and VOSviewer software to allow bibliometric visualization. RESULTS: There was a very poor correlation between the number of mentions and the number of citations (r = 0.0202). Most articles discussed on technical innovations associated to orthognathic surgery, majority related to virtual planning (n = 26). Other topics considered interesting to internet readers were complications (n = 18), surgical technique (n = 14), and psychological aspects/quality of life (n = 13). CONCLUSION: Online interest in orthognathic surgery closely aligns with the level of academic interest but is also influenced by factors such as location and economic status. The internet is a powerful tool for disseminating scientific research to a broad audience, making it more accessible and engaging than traditional academic channels.

Top 100 cited articles in the thromboangiitis obliterans: a bibliometric analysis and visualized study.

OBJECTIVE: Thromboangiitis obliterans (TAO) is one of the most common types of peripheral arterial disease (PAD). This study aimed to explore the characteristics of the top 100 most cited articles in the TAO. METHODS: A bibliometric analysis based on the Web of Science (WOS) database was performed. Literature was retrieved and ranked by the citations. Listed below are the top 100 citations, including original articles, reviews, full-length proceeding papers, and case reports that were included for analysis. The type of literature, research areas, and languages were recorded. The trends of citations including the total citations, an analysis of publication and citation numbers were conducted each year. We analyzed citations from highly cited countries, authors, institutions, and journals. Research hotspots were gathered by a visualized analysis of author keywords. RESULTS: Most of the highly cited literature was original articles. A rising trend was observed in the number of citations per year. The peaks in the number of highly cited articles appeared in the year 1998 and 2006. The majority of the articles focused on the cardiovascular system and surgery. Journal of Vascular Surgery published most of the highly cited articles. The USA and Japan contributed nearly half the number of highly cited articles. Mayo Clinic and Nagoya University were highly cited institutions. Shionoya S and Olin JW were both the author with the largest number of citations and the most highly cited author in the reference. Articles that were highly cited most often addressed the following topics: "vasculitis", "autoimmune disease", and "critical limb ischemia". Keywords that were mostly used in recent years were "stem cell therapy", "progenitor therapy", and "immunoadsorption". The detection of bursts of author keywords showed the following: "permeability", "differentiation", and "critical limb ischemia" are recent keywords that have burst. CONCLUSIONS: In this study, the highly cited contributors in the field of TAO research were identified. Most cited articles in the top 100 focused on the cardiovascular system and surgery. Treatment and pathophysiology including stem cell therapy, progenitor therapy, genetics, autoimmunity, and inflammation are the hotspots of TAO.

Top 100 highly cited papers from India on COVID-19 research: A bibliometric analysis of the core literature.

BACKGROUND AND AIMS: This study aimed to assess the current status of India's COVID-19 research from the top 100 most cited papers, using bibliometrics methods and indicators and suggest strengths and weaknesses. METHODOLOGY: Publications on COVID-19 research from India between December 2019 and 22 August 2023 were retrieved from the Scopus database. From 37101 studies retrieved, the first top 100 Highly Cited Papers (HCPs) having received 270 to 2931 citations, were identified. RESULTS: The top 100 most cited Indian papers were published from 2020 to 2023, with the majority (75) in the year 2021, followed by 24 in 2022. They were cited a total of 56661 times (average - 566.61 times). The 242 authors of these HCPs were from 159 Indian organizations, and the articles were published in 60 journals. 29 % and 59 % of these HCPs received external funding support and were involved in international collaborations, respectively. There was poor collaboration among Indian research institutions and a dearth of funding from India. None of the Indian HCPs figured in the global 100 HCPs. CONCLUSIONS: Although citations of research papers published from India increased during COVID-19, limited collaboration, inadequate funding, and subpar publications hindered Indian scientists. To enhance India's research landscape, we propose dismantling barriers, nurturing collaboration, and encouraging knowledge exchange among domestic institutions.

The purpose of this study was to estimate the trends and state of research in periprosthetic fractures. Methods: Articles on periprosthetic fractures were retrieved from the Web of Science database. Information about each article, including country/region, author, institution, issue, journal, and keywords, was recorded for bibliometric analysis. The analysis included only English-language articles from 2000 to 2021, from 58 countries and regions. Results: A total of 1668 original articles meeting the research requirements were obtained. The number of manuscripts on periprosthetic fractures has experienced rapid growth, especially since 2009. Productivity was dominated by the USA, followed by the UK and Germany. The most prolific institution was Mayo Clinic. The most cited article was published by Sharkey, P.F. in 2002. The five most frequent keywords were "periprosthetic fractures", "total hip arthroplasty", " revision", "arthroplasty", "total knee arthroplasty". Conclusions: Based on the current trends of globalization, there is a rising trend in publications on periprosthetic fractures, with the largest annual contributions made by the United States. The most influential contributors are researchers from the United States and England. In addition, Journal of Arthroplasty is the journal with the most research in this field. Geriatric trauma and dual mobility are the new hot topics in this field. Together these studies have played a key role in periprosthetic fractures decision-making and management.

A global science mapping analysis on odontogenic infections.

OBJECTIVES: Odontogenic infections are common and a topic of core interest for dentists, and maxillofacial surgeons. The aim of this study was to conduct a bibliometric analysis of the global literature on odontogenic infection and explore the top 100 most cited papers to identify the common causes, sequelae and management trends. METHODS: Following a comprehensive literature search, a list of top 100 most cited papers was created. The VOSviewer software (Leiden University, The Netherlands) was used to create a graphical representation of the data, and statistical analyses were performed to analyze the characteristics of the top 100 most cited papers. RESULTS: A total of 1,661 articles were retrieved with the first article published in 1947. There is an exponential upward trend on the number of publications (R2 = 0.919) and a majority of papers are in English language (n = 1,577, 94.94%). A total of 22,041 citations were found with a mean of 13.27 per article. The highest number of publications were recorded from developed countries. There was a male predilection in the reported cases and the most common sites included the submandibular and parapharyngeal spaces. Diabetes mellitus was identified as the commonest co-morbidity. Surgical drainage was ascertained to be the preferred method of management. CONCLUSIONS: Odontogenic infections remain prevalent and have a global distribution. Although prevention of odontogenic infection through meticulous dental care is ideal, early diagnosis and prompt management of established odontogenic infections is important to avoid morbidities and mortality. Surgical drainage is the most effective management strategy. There is lack of consensus regarding the role of antibiotics in the management of odontogenic infections.

The 100 Most-Cited and Influential Articles in Collegiate Athletics.

Background: Bibliometric citation analyses have been widely used in medicine to help researchers gain foundational knowledge about a topic and identify subtopics of popular interest for further investigations. There is a lack of similar research in collegiate athletics. Purpose: To identify the 100 most-cited research publications related to collegiate athletics. Study Design: Cross-sectional study. Methods: The Clarivate Analytics Web of Knowledge database was used to generate a list of articles relating to collegiate athletics on January 24, 2022. Articles were filtered by the total number of citations, and the 100 most-cited articles were selected. For each article, we identified and analyzed the following: author name, publication year, country of origin, journal name, article type, main research topic area, competitive level, sex of study population, and level of evidence. Results: Of the top 100 most-cited articles, 63 were related to medicine. In total, 96% of articles were published in the United States, and 80% were published in the year 2000 or later. Of the top 100 articles, 85 were observational; only 5 were experimental. The sport most represented was soccer, followed by football, baseball, and basketball. Of the top 100 articles, 21 were published in a single journal, the American Journal of Sports Medicine. Ten authors published ≥5 of the top 100 most-cited studies. Conclusion: The majority of top 100 articles were published in the United States after 1999 and primarily focused on medicine-related topics. Soccer was studied by more articles than football, baseball, and basketball. An author's prestige may have influenced the likelihood of citation. The top 100 most-cited studies provide researchers, medical students, residents, and fellows with a foundational list of the most important and influential academic contributions to the literature on collegiate athletics.

Global trends of dalbavancin: A bibliometric analysis.

WHAT IS KNOWN AND OBJECTIVE?: Dalbavancin is used against gram-positive pathogens such as Staphylococcus aureus in acute bacterial skin and skin-structure infections. METHODS: Our main goal was to identify the key articles sustaining the current knowledge of this drug's therapeutic possibilities through a bibliometric analysis of the available literature. RESULTS AND DISCUSSION: On 15 March 2021, we searched the Web of Science electronically for documents that contain within its title the term "dalbavancin." We found a total of 675 documents that average 20.23 citations/publication with a density of 682.60 citations per/year, yielding an h-index of 58. After ranking them by the number of times cited, we extracted the top 100 most-cited records (T100). Number of citations/publication ranged from 13 to 231, publication years were 2002-2019, with the top-cited article published in 2014. All T100 publications were written in English. JMI Laboratories was the institution with the most articles in the T100 (22 documents), and the United States was the top country (75 documents). Five authors participated in at least five of the T100, led by Jones RN with 20 articles. Positions #1, #2, #5, and #9 were clinical trials for acute bacterial skin and skin structure infections (ABSSSI), the on-label indication for dalbavancin. Only one article in the top 10 (T10) was an off-label indication that was published in 2005 with 186 citations, and occupied the third position among the T100. Using the VOSviewer© programme, we observed that the most used keywords were: dalbavancin, lipoglycopeptide, gram-positive, osteomyelitis, vancomycin, and MRSA. WHAT IS NEW AND CONCLUSIONS?: Our study identifies the most significant research on dalbavancin, including the highest impact publications, and highlights the recent trend of dalbavancin in new therapies. The T10 articles include the most important dalbavancin clinical trials, along with other studies and reviews that support the growing role of this antibiotic in clinical use. Emphasis has been on the favourable pharmacokinetic profile that allows administration once-weekly, with minimal risk of severe adverse events.

Pediatric urology research in 2020: A bibliometric analysis of the top 100 most cited articles.

BACKGROUND: Pediatric Urology deals with genitourinary diseases. Present study aimed to collect the top-cited article in Pediatric Urology in order to define the most debated and studied topics. METHODS: The journals reported in "Urology & Nephrology" category of the 2019 edition of Journal Citation Reports, together with the most relevant journals of "Transplantation," "Pediatrics," and "Surgery" categories, were browsed. The articles of interest in Pediatric Urology with more than 50 citations were collected. A bibliometric analysis was performed to collect the top 100 cited articles. RESULTS: The top-cited articles were published in 27 journals (23%), with a median impact factor of 2.676 (IQR 1.981-5.642). Seventeen of them (63%) belonged to "Urology and Nephrology" category. The median number of citations was 82 (IQR 64-113). The most productive journal, with 23 articles, was "The Journal of Urology." Forty-eight top-cited articles were Guidelines or Reviews of the literature and only four papers were randomized controlled trials. The most relevant topic was "congenital anomalies" with 18 articles. As to minimally invasive surgery, eight studies were identified. All of them dealt with robotic-assisted laparoscopic surgery. Two articles reported the current evidence about transitional care. CONCLUSIONS: The top-cited articles were dispersed among journals of different areas. Current scientific literature deal with congenital anomalies, more specifically with obstructive uropathies and hypospadias. In the last decade, one of the most relevant innovation in pediatric urology was the introduction of robotic surgery. Transitional care has become a timely topic.

Vancomycin Use in Children and Neonates across Three Decades: A Bibliometric Analysis of the Top-Cited Articles.

Vancomycin is frequently prescribed in pediatrics, especially in intensive care unit settings, to treat Gram-positive bacterial infections. This work aims to collect the top-cited articles of pediatric and infectious diseases areas to gather the current evidence and gaps of knowledge on the use of vancomycin in these populations. The most relevant journals reported in the "pediatrics" and "infectious diseases" categories of the 2019 edition of Journal Citation Reports were browsed. Articles with more than 30 citations and published over the last three decades were collected. A bibliometric analysis was performed and 115 articles were retrieved. They were published in 21 journals, with a median impact factor of 4.6 (IQR 2.9-5.4). Sixty-eight of them (59.1%) belonged to "infectious diseases" journals. The most relevant topic was "bloodstream/complicated/invasive infections", followed by "antibiotic resistance/MRSA treatment". As for population distribution, 27 articles were on children only and 27 on neonates, most of which were from intensive care unit (ICU) settings. The current literature mainly deals with vancomycin as a treatment for severe infections and antibiotic resistance, especially in neonatal ICU settings. Lately, attention to new dosing strategies in the neonatal and pediatric population has become a sensible topic.

A Bibliometric Analysis of the Top Cited Articles in Sports and Exercise Medicine.

BACKGROUND: Although citation analysis is common in many areas of medicine, there is a lack of similar research in sports and exercise medicine. PURPOSE: To identify and examine the characteristics of the 100 top cited articles in the field of sports and exercise medicine in an effort to determine what components make an article highly influential. STUDY DESIGN: Cross-sectional study. METHODS: The Web of Science, Scopus, and PubMed databases were used to determine the 100 top cited articles from 46 journals in the field of sports and exercise medicine. Each of the 100 articles was then analyzed by 2 independent reviewers, and results were compared. Basic information was collected, including journal title, country of origin, and study type. Different categories were compared using descriptive statistics of counts or percentages. RESULTS: The 100 top cited articles were published in 15 of the 46 identified sports and exercise medicine journals, with the most prolific being Medicine and Science in Sports and Exercise (n = 49), American Journal of Sports Medicine (n = 18), and Sports Medicine (n = 7). In terms of country of origin, the top 3 contributors were the United States (n = 65), Canada (n = 9), and Sweden (n = 8). The most commonly researched anatomic areas were the knee (n = 15) and the brain (n = 3). Narrative reviews were the most common study type (n = 38), and only a single study on the 100 top cited articles list used a randomized controlled trial design. The most prevalent fields of study were exercise science (55% of articles) and well-being (16% of articles). CONCLUSION: Narrative reviews from the United States and published in English-language journals were the most likely to be highly cited. In addition, the knee was a common anatomic area of study on the top cited list of research in sports and exercise medicine.

Bibliometric Analysis of the Top-Cited Articles on Unicompartmental Knee Arthroplasty.

BACKGROUND: Unicompartmental knee arthroplasty (UKA) has been proven to be an effective surgical technique for unilateral compartment osteoarthritis. The purpose of this study is to identify and analyze the top 100 cited articles in the field of UKA research. METHODS: Publications on UKA from 1980 to 2020 in the Web of Science database were retrieved. The characteristics of the top 100 cited articles were analyzed, including information of publications and citations, level of evidence, and research interests. RESULTS: The number of publications and citations increased over time. The majority of the highly cited articles were from the Nuffield Orthopedic Centre (Oxford, England) and the Brigham and Women's Hospital (Boston, USA). Long-term outcome of UKA and comparison between UKA and TKA gathered most research interests. The most frequently occurring keywords were "survival" and "revision." Since 2012, "life quality" and "robotics" have been used. There was no level I evidence, and most studies provided level IV evidence. CONCLUSION: There was a rising trend in publications and citations in the field of UKA research, the majority of them were from a few centers, and were low-level evidence. Most studies focused on the long-term outcomes of UKA; in recent years, patient satisfaction and navigation surgery have become new research trends.

Top-cited articles in medical professionalism: a bibliometric analysis versus altmetric scores.

INTRODUCTION: Citation 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. OBJECTIVES: The aims of the study were 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 the 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=0.150) 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. CONCLUSIONS: Altmetric 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.

What can we learn from top-cited articles in inflammatory bowel disease? A bibliometric analysis and assessment of the level of evidence.

BACKGROUND AND OBJECTIVES: Despite increasing number of publications in inflammatory bowel disease (IBD), no bibliometric analysis has been conducted to evaluate the significance of highly cited articles. Our objectives were to identify the top-cited articles in IBD, assessing their characteristics and determining the quality of evidence provided by these articles. DESIGN AND OUTCOME MEASURES: IBD and related terms were used in searching the Web of Science to identify English language articles. The 50 top-cited articles were analysed by year, journal impact factor (JIF), authorship, females in authorship, institute, country and grants received. The level of evidence was determined using the Oxford Centre for Evidence-Based Medicine guidelines. RESULTS: The number of citations varied from 871 to 3555 with a total of 74 638, and a median 1339.50 (IQR=587). No correlations were found between the number of citations and number of years since publication (r=0.042, p=0.771), JIF (r=0.186, p=0.196), number of authors (r=0.061, p=0.674), females in authorship (r=0.064, p=0.661), number of institutes (r=0.076, p=0.602), number of countries (r=0.101, p=0.483) or number of grants (r=-0.015, p=0.915). The first authors were from the USA (n=24), the UK (n=6), Germany (n=5), France (n=5), Belgium (n=3) and Canada (n=3). The levels of evidence were 12 articles at level 1b, 9 articles at level 3a and 15 articles at level 3b and fewer were at other levels. CONCLUSIONS: Research papers represented 66% of articles. The majority of items have reasonably high levels of evidence, which may have contributed to the higher number of citations. The study also shows a gender gap in authorship in this area.
