Redundant surgical publications: tip of the iceberg?

BACKGROUND: A redundant publication is one which duplicates previous, simultaneous, or future publications by the same author or group or, alternatively, could have been combined with the latter into one paper. As there is no information about the extent of this problem in the surgical literature, we set out to assess the incidence, spectrum, and salient characteristics of redundant publications in 3 leading surgical journals. METHODS: Original articles (excluding reviews, editorials, abstracts, and letters) published during 1998 in the journals Surgery, The British Journal of Surgery, and Archives of Surgery were searched by using the on-line search engine PUBMED. Each original article was scrutinized to identify redundancy by combining the names of the first, second, and last authors with a few key words from the title. Papers were defined as "suspected" redundant publications if they were found to address the same topic as the "index" article and shared some or most of the elements of methodology, results, or conclusions. The full versions of all suspected papers were retrieved and compared with the index articles. A grading system was developed to define several types of redundant publications: A. "dual"; B. "potentially dual"; C. "salami-slicing." RESULTS: A total of 660 articles were screened. There were 92 index articles (14%) leading to 147 suspected papers found in other journals, representing some potential form of a redundant publication. The vast majority of suspected papers were published within approximately a year of the index paper and were not cited by the latter. Most (69%) of the suspected papers were also published in surgical journals. Only 12 (8.1%) appeared in, or originated from, a "local-foreign" journal. Twenty (13.6%) of the suspected papers met the criteria for dual publications, 50 (34%) for potentially dual publications, and 77 (52.4%) were considered products of salami-slicing. CONCLUSIONS: Almost 1 in every 6 original articles published in leading surgical journals represents some form of redundancy. Current on-line search technology provides an effective tool for identifying and tracing such publications, but it is not used routinely as part of the peer review process. Redundancies occur in several well-defined patterns; the phenomenon is widespread, and it cuts across the entire spectrum of surgeons in the United States and abroad. Redundant publications must be recognized not as a mere nuisance but as a real threat to the quality and intellectual impact of surgical publishing.     

One Hundred Citation Classics in General Surgical Journals

The number of times an article is cited in scientific journals reflects its impact on a specific biomedical field or specialty and reflects the impact of the authors’ creativity. Our objective was to identify and analyze the characteristics of the 100 most frequently cited articles published in journals dedicated to general surgery and its close subspecialties. Using the database (1945–1995) of the Science Citation Index of the Institute for Scientific Information, 1500 articles cited 100 times and more were identified and the top 100 articles selected for further analysis. The 100 articles were published between 1931 and 1990, with more than two-thirds of them published after 1960. The mean number of citations per article was 405, (range 278–1013). Altogether, 84 of the articles originated from North America (USA 78, Canada 6) and the UK (12). New York State led the list of U.S. states with 14, and Harvard and Columbia University led the list of institutions with 6 articles each. The 100 articles were published in 10 surgical journals led by theAnnals of Surgery (n = 40), followed bySurgery (n = 15), Archives of Surgery (n = 12), Surgery, Gynecology and Obstetrics (n = 11), and British Journal of Surgery (n = 10). A total of 80 of the articles reported clinical experiences, 6 were clinical review articles, and 14 dealt with basic science. Eighteen articles reported a new surgical technique and six a prosthetic device. Gastrointestinal surgery and trauma and critical care led the list of the surgical fields, each with 25 articles, followed by vascular surgery (n = 15). Thirty-four persons authored two or more of the top-cited articles. This list of the top-cited papers identifies seminal contributions and their originators, facilitating the understanding and discourse of modern surgical history and offering surgeons hints about what makes a contribution a "top-cited classic." To produce such a "classic" the surgeon and his or her group must come up with a clinical or nonclinical innovation, observation, or discovery that has a long-standing effect on the way we practice—be it operative or nonoperative. Based on our findings, to be well cited such a contribution should be published in the English language in a high-impact journal. Moreover, it is more likely to resonant loudly if it originates from a North American or British "ivory tower."     

Factors associated with citation rates in the orthopedic literature

INTRODUCTION: Investigators aim to publish their work in top journals in an effort to achieve the greatest possible impact. One measure of impact is the number of times a paper is cited after its publication in a journal. We conducted a review of the highest impact clinical orthopedic journal (Journal of Bone and Joint Surgery, American volume [J Bone Joint Surg Am]) to determine factors associated with subsequent citations within 3 years of publication. METHODS: We conducted citation counts for all original articles published in J Bone Joint Surg Am 2000 (12 issues). We used regression analysis to identify factors associated with citation counts. RESULTS: We identified 137 original articles in the J Bone Joint Surg Am. There were 749 subsequent citations within 3 years of publication of these articles. Study design was the only variable associated with subsequent citation rate. Meta-analyses, randomized trials and basic science papers received significantly more citations (mean 15.5, 9.3 and 7.6, respectively) than did observational studies (mean retrospective 5.3, prospective 4.2) and case reports (mean 1.5) (p = 0.01). These study designs were also significantly more likely to be cited in the general medical literature (p = 0.02). CONCLUSION: Our results suggest that basic science articles and clinical articles with greater methodological safeguards against bias (randomized controlled trials and meta-analyses) are cited more frequently than are clinical studies with less rigorous study designs (observational studies and case reports).     

Research advances in the diagnosis and treatment of moyamoya disease: a bibliometric analysis

Moyamoya disease is a rare cerebrovascular condition involving stenotic carotid arteries and the formation of abnormal blood vessels. In this study, we aimed to characterize the key players involved in moyamoya research at the individual and institutional level and to identify the critical publications that have advanced our understanding of this disease. We performed a title-specific search of the Web of Science database using the search term “moyamoya” for publications dating from 1900 to April 2020. The 100 most frequently cited articles were obtained, screened for duplicates, and reviewed by 2 independent reviewers. These 100 articles were cited an average of 150 times each (range, 74 to 1,360 citations per article). Publication dates ranged from 1969 to 2016, with the largest number of publications (n=40) cited between 2000 and 2009. The article with the greatest number of citations (1,360 citations) was “Cerebrovascular ‘moyamoya’ disease: disease showing abnormal net-like vessels in base of brain,” by Suzuki and Takaku, published in the Archives of Neurology, 1969. Stroke published the greatest number of the most frequently cited articles (23 of 100). The institution that contributed the most articles was Tohoku University (16%); the majority of the most frequently cited articles originated in Japan (62%). We identified the 100 most cited articles on moyamoya disease over the past 51 years to recognize significant and impactful works. These results can be used as a guide to evaluate our current understanding of moyamoya disease and to direct future efforts.

     

Los top 100. Revisión de los artículos más citados en cirugía

Introduction

We performed a study of the top 100 most cited articles in the five general surgery journals with the highest impact according to Journal Citation Report.

Top 100. Revisión de los artículos más citados sobre cirugía laparoscópica del páncreas

IntroductionThe number of citations is considered as an indirect indicator of the merit of an article, journal or researcher, although it is not an infallible method to determine scientific quality. Our goal is to determine the characteristics of the articles most cited about pancreas and laparoscopy.MethodsWe performed a search of all articles published in any journal about pancreas and laparoscopy until September 2019 and selected the 100 most cited papers. We recorded number of citations, journal, year of publication, quartil, impact factor, institution, country, authors type of paper, type of surgery, topic and area.ResultsThe top 100 citations account 10,970 citations in total. The journal with the most articles is Surgical Endoscopy and 2007 is the year with the highest number of articles in the top 100 citations. The percentage of publications from America and Europe are similar.Case series is the most frequently paper, outcomes/morbidity is the most frequently discussed topic, and distal pancreatectomy is the most frequently type of surgery.ConclusionsThis bibliometric study on pancreas and laparoscopy is conditioned by the time factor, since laparoscopy has arrived later at pancreatic surgery, probably due to the morbidity and mortality associated with pancreatic surgery and the need for a high specialization in this field. The literature is recent and scarce. More and better-quality studies are needed in this field.

Contribution of the Southern Association for Vascular Surgery to the scientific literature

The Southern Association for Vascular Surgery (SAVS) has played a significant role in the development and evolution of vascular surgery. This study was designed to document the contribution to the scientific literature and to highlight the important publications from the annual meetings of the SAVS on its 25th anniversary. A total of 413 (73%) of the 569 "free papers" presented at the SAVS Annual Meeting were published in journals that are identified in MEDLINE, and most (71%) were published in the Journal of Vascular Surgery. Carotid/cerebrovascular disease, leg ischemia, and basic considerations were the most common subject matters overall, although there has been a recent decrease in the percentage of articles about basic considerations and aortic aneurysms while there has been an increase in those about endovascular therapy, vascular laboratory/imaging, and visceral/renal artery disease. The 413 papers were cited a mean of 18 +/- 20 (+/- SD) times (range 0-143) with 32 papers cited more than 39 times and 17 papers cited more than 59 times. A panel of three reviewers identified 42 significant articles, among which 8 were considered seminal by 2 of the 3 reviewers. The papers presented at the annual meeting of the SAVS have made a significant contribution to the scientific literature in terms of both quantity and quality. These efforts have laid the foundation for the next quarter century and have raised the level of expectation.     

Citation classics: Top 50 cited articles in bariatric and metabolic surgery

BackgroundThe number of times an article has been cited reflects its influence in a specific field. The aim of this study was to identify and characterize the most highly cited articles published on bariatric and metabolic surgery.MethodsThe 50 most frequently cited articles in bariatric and metabolic surgery were identified from the Scopus database in December 2013.ResultsThe median number of citations was 383.5 (range 275–2482). Most of the articles were published from 2000–2012 (n = 35), followed by 1990–1999 (n = 12), then before 1990 (n = 3). These citation classics came from 8 countries, with the majority originating from the United States (n = 34), followed by Sweden (n = 4) and Australia (n = 4). The 50 articles were published in 20 journals, led by New England Journal of Medicine (n = 9) and Annals of Surgery (n = 9). Only 10 of the articles were published in obesity-specific journals. The level of evidence of the 49 clinical publications and 1 animal study consisted of level I (n = 5), II (n = 11), III (n = 9), IV (n = 19), and V (n = 6). Meta-analyses were 16% of the total citations. Metabolic (n = 12) and survival (n = 6) effects of surgery were among the most common fields of study.ConclusionExtending from the early 1950s through the voluminous growth period of the early 2000s, the field of bariatric and metabolic surgery led to the emergence of many top-cited scientific articles. These articles have provided the scientific basis for the only currently effective treatment for severe obesity. Articles published in high-impact journals, innovative observational studies, meta-analyses, survival analyses, and research on postoperative metabolic changes are most likely to be cited in the field of bariatric surgery.     

Global and Current Research Trends of Unilateral Biportal Endoscopy/Biportal Endoscopic Spinal Surgery in the Treatment of Lumbar Degenerative Diseases: A Bibliometric and Visualization Study

The study aimed to make a bibliometric analysis of the current research situation in unilateral biportal endoscopy/biportal endoscopic spinal surgery (UBE/BESS). Research data sets were acquired from the Web of Science database. The study chosed “biportal endoscopic spinal surgery” OR “two portal endoscopic spinal surgery” OR “percutaneous biportal endoscopic decompression” OR “unilateral biportal endoscopy” OR “irrigation endoscopic discectomy” as the search terms. The literature search was limited to articles published before March 5, 2021. We only included original articles and reviews. VOS viewer and Citespace software were used to analyze the data and generate visualization knowledge maps. Annual trend of publications, distribution, H‐index status, co‐authorship status, and research hotspots were analyzed. A total of 74 publications met the requirement. The sum number of citations was 31,204, in which 19,336 were no self‐citations. The average citation of all the papers was 21.84 times. The H‐index of all the publications was 85. South Korea''s total number of articles was far higher than that of other countries and regions (61, 82.4%), followed by United Arab Emirates, Egypt, and Peoples Republic of China (three, ranking second, accounting for 12.2% of the total). For the most productive authors, Choi ranked first with 21 articles, Kim ranked second with 16 articles, and Heo ranked third with 12 articles. The journal with the greatest number of publications was World Neurosurgery, with a total of 18 (39.1%) papers. Clinics in Orthopedic Surgery ranked second with six (13.0%) papers. In third place, there were fix articles published by Asian Spine Journal and Neurospine, accounting for 21.8% of the total articles. These top three journals accounted for 73.9% of all the papers. Spondylolisthesis and endoscopic decompression were the research hotspots in recent years. The number of publications has showed an upward trend with a stable rise in recent years. South Korea is the country with the highest productivity, not only in quality, but also in quantity. Barun Hosp and Leon Wiltse Mem Hosphave published most articles. Choi is the most productive author. World Neurosurgery is the most productive journal. Spondylolisthesis and endoscopic decompression are the research hotspots in recent years. Indeed, this study provides new insight into the growth and development of UBE/BESS.     

Last five years audit of Journal of Clinical Orthopaedics and Trauma (JCOT) - A scientometric analysis

BackgroundWe have studied the growth of Journal of Clinical Orthopaedics and Trauma (JCOT), the official journal of the Delhi Orthopaedic Association indexed in PubMed, Scopus and Embase, along with an analysis of citation trends and levels of evidence of published articles in the last five years.MethodsSCOPUS and PubMed databases (2015–19) were used to extract publication-related data for the last five years. The official website of the journal was also used to retrieve issue-specific data. An audit of recent publications in the JCOT was conducted focusing on number of issues and publications(year wise), types of articles published, review speed, level of evidence of publications, types of publication(speciality wise), number of publications in PubMed and SCOPUS, number of citations(year wise), national and international authorship and the Cite Scores.ResultsThe submissions were increased by 2.8 times and the citations rocketed to 16.6 times in 2019, compared to 2015. A total of 890 papers were there and the journal was cited 1702 times in the last five years. More articles with higher levels of evidence papers are now being published.ConclusionThere has been a significant increase in the numbers of submissions, publications, citations, Cite Score, h-index and contribution by the International authors. Its Editorial efficiency has also been outstanding with timely reviews and editorial decisions. The JCOT has become increasingly internationally relevant in the last five years, in the orthopaedic community. However, JCOT needs to publish more papers with a higher level of evidence like Systematic reviews, Meta-analyses, Randomized Controlled Trials and should only publish top-class lower hierarchy papers (like Case reports, Case-controlled and Retrospective studies).
