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.     

Bibliometric analysis of the top 50 most cited publications of the Journal of Clinical Orthopaedics and Trauma

BackgroundThe Journal of Clinical Orthopaedics and Trauma (JCOT) is one of the top three orthopaedic journals from India. We set out to analyse the top 50 cited articles from JCOT since indexing in PubMed and Scopus.MethodsWe looked into the bibliometrics of the top 50 cited articles and compared citations from PubMed and Scopus, and depicted outputs from VOS viewer analysis on co-authorship and keywords.ResultsTotal citations for top-cited articles were 1076 in numbers, with a maximum of 103.2016 and 2018 were the most productive years. The major contribution was from India with 74%, followed by the USA. New Delhi published maximally at 72%. Clinical topics and narrative reviews were the most common types of studies. Trauma and Adult reconstruction was the most common sub-specialities, and Level 4 was the most frequent level of study. The basic science and COVID-19 related articles received the maximum citations. The authors from Indraprastha Apollo Hospitals published the maximum number of top-50 cited articles in the JCOT.ConclusionsThere is a steady increase in the number of publications in the JCOT, with an increasing number of citation counts. Both the Indian and foreign authors have been publishing in this journal at a comparative rate. Although the citation counts in Scopus are more than those in PubMed for given articles, more than 80% of articles are listed in both databases as top 50 cited articles. The majority of top-cited articles belonged to trauma and adult reconstruction, level III studies, and narrative reviews.

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.

     

The Top 100 Cited Articles on Plantar Fasciitis: A Bibliometric Analysis

Plantar fasciitis is a common musculoskeletal complaint seen in clinical practice. The objective of this study was to perform a bibliometric analysis of the top 100 articles published on the topic of plantar fasciitis. The Web of Science platform was used to search for articles on plantar fasciitis published between 1975 and 2021. Articles were subsequently ranked from the most to least cited. The top 100 studies were analyzed and their characteristics described. A total of 1859 articles were identified. The most cited article was “A retrospective case-control injuries analysis of 2002 running” published by Taunton JE et al in the British Journal of Sports Medicine in 2002. This article had a total of 910 citations. The mean number of citations per article in the top 100 was 139.95 (range 83-910). The majority of articles were published between the years 2000 to 2009 (n = 56). The USA had the highest number of publications (n = 55), while ‘Foot and Ankle International’ was the journal with the most publications in the top 100 (n =10). Plantar fasciitis is a well-studied topic. Despite this, however, a significant interest in plantar fasciitis research remains among clinicians and researchers evident by the high number of recent studies published on this topic. It is anticipated that these more recent studies will become highly cited over time and as such, this bibliometric analysis should be continuously updated.

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.

The 100 most cited papers in foot and ankle surgery

BackgroundThe number of citations of a paper gives an indication of an article's merit and importance within a medical specialty. We identify and analyse the 100 most cited papers in foot and ankle surgery.MethodThe Science Citation Index Expanded was searched for citations in 15 respected journals containing foot and ankle articles. Papers were analysed for subject, authorship, institution, country and year of publication. The average yearly citation was compared to total number of citations.Results3501 foot and ankle papers were returned. The maximum number of citations was 1084 and the mean was 104. The top 100 papers were published between 1979 and 2007, with the majority published in the last decade. The ankle was the most important anatomical region discussed, and basic science and degenerative disease were popular topics. We found a large discrepancy between the total number of citations with average yearly citation.ConclusionFoot and ankle surgery is a young and rapidly developing sub-specialty within orthopaedics. Recently there has been a significant increase in influential papers published. Certain topics are popular indicating their importance within the field. This study highlights important papers in foot and ankle surgery giving an insight into readership.     

The fifty most cited Latin-American articles in the orthopaedic literature

Purpose

The number of citations of an article is a marker of its academic influence. Several medical specialties, including orthopaedics, have ranked the articles with more citations. We identified the 50 most cited orthopaedic articles from Latin-America and analyzed the characteristics that made them citable.

Methods

Science Citation Index Expanded was searched for citations of articles originated in Latin-America, published in any of the 63 journals in the category “Orthopaedics” from 1988 to 2013. We created a list ranking the 50 most commonly cited articles and determined the citation density (Citations/years since publication). Information noted for each article included authors, year of publication, country of origin, source journal, article type, and field of research.

Results

Latin-American countries were the origin of 1 % of orthopaedic articles. The top 50 most cited articles had between 29 and 150 citations (mean, 44.48); the citation density ranged from 1.43 to 15.5 citations/years (mean, 5.25). The articles were published in 19 of the 63 journals (11 general and eight sub-specialty journals), and all were published in English. Most articles (n = 29) were published in 2000 or later. The majority were clinical articles (n=40), and the most common fields were arthroscopy (n = 15) and hip surgery (n = 13). The top 50 articles originated mainly from Brazil (n = 20) and Argentina (n = 15).

Conclusions

This top 50 list displays articles that have become important references for the orthopaedic scientific community. Researchers may use this work to make their future publications more influential on future investigators.     

The Top 100 Most-Cited Articles on Hallux Valgus

BackgroundTo perform the citation and content analysis of 100 articles on Hallux valgus from the most cited to the least.Materials and methodsArticles published on Hallux valgus between 1980 and 2020 were analyzed by making use of the Web of Science database. Articles were ranked from most cited to the least. Content analysis of all articles was also carried out. Original research articles, reviews, and clinical trials were included in the study whereas case reports were excluded from the study.ResultsThe total number of citations of the 100 most-cited articles was 7,697. The most-cited article was ‘Prevalence of hallux valgus in the general population; systematic review and meta-analysis’ published by Sheere Nix in Journal of Foot and Ankle Research in 2010. The country where the articles were mostly produced was USA (n = 46). The most interesting issue was the osteotomy techniques and changes in Hallux valgus surgery.ConclusionThe treatment of the Hallux valgus disease is still discussed today. Citation analyses have shown that surgical developments related to HV surgery still attract attention, and this information will be updated continuously in line with the increasing number of articles.     

Citation analysis of the most influential articles on traumatic spinal cord injury

Objective: We conducted a citation analysis in order to catalog and pay tribute to the 100 most influential clinical research articles in traumatic spinal cord injury.

Design: The Thomson Reuters Web of Science was searched in a two-step process without time period limitations. Review articles were excluded. In the first stage of data extraction, a Boolean query was used to identify the top 100 most cited clinical papers on traumatic spinal cord injury. One hundred and seven keywords were manually chosen and extracted from titles and abstracts. A second Boolean query used these keywords to broaden search results. The top 100 articles from this second stage search comprised the final list.

Outcome Measures: For each article, measures evaluated were number of citations, average number of citations per year, time elapsed before first citation, and time elapsed until the year in which each article received its respective highest number of citations in a one-year period.

Results: 119,991 articles were found in the second stage search. The top 100 most cited articles meeting inclusion criteria were identified within the first 2,104 results. Archives of Physical Medicine and Rehabilitation was the most represented journal, with 20 of the top 100 articles. The top 100 list averaged 255 citations per article. The most highly cited article was the NASCIS 2 trial by Bracken et al., cited 1500 times, which investigated the efficacy of methylprednisolone or naloxone for spinal cord injury.

Conclusion: Clinical research in traumatic spinal cord injury has grown over time, expanding to encompass rehabilitation and experimental therapies in addition to acute management trials. The list may serve as an archive and reference for further studies in this field.     

Citation classics in main pain research journals

The number of citations of an article in scientific journals reflects its impact on a specific biomedical field and its recognition in the scientific community. In the present study, we identified and analyzed the characteristics of the 100 most frequently cited articles published between 1970 and 2010 in journals pertaining to pain research and related fields. These articles were identified using the database of the Science Citation Index (1970 to present). The most cited article received 3,017 citations and the least cited article received 302 citations, with a mean of 585 citations per article. These citation classics were published in six high-impact journals, led by Pain (84 articles). Of the 100 articles, 39 were observational studies, 25 were review articles, and 20 concerned basic science. The articles originated from 14 countries, with the United States contributing 47 articles; 67 institutions produced these 100 top-cited articles, led by National Institutes of Health of the United States (8 articles) and University College London (6 articles); 18 persons authored 2 or more of the top-cited articles. This analysis of the top citation classics allows for the recognition of major advances in pain research and gives a historical perspective on the scientific progress of this specialty.     

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.     

Thromboprophylaxis across orthopaedic surgery: Bibliometric analysis of the most cited articles

PurposeOne of the most common adverse events after orthopaedic surgery, with a potential for subsequent serious morbidity and mortality is venous thromboembolism (VTE). Bibliometric analysis has been performed regarding many topics and across orthopaedics. As DVT prophylaxis is a major component of both orthopaedic surgery considerations and research, a bibliometric analysis in this area would prove beneficial in not only in understanding the research done in the field thus far, but would also direct future research efforts.MethodsThe Web of Science (WoS) database from the Institute of Scientific Information (ISI) was used to compile articles for bibliometric analysis using Boolean search: ((Orthopaedic1 OR Orthopaedic1) AND (thromboprophylaxis OR Thromboembolism OR Deep vein thrombosis OR thrombus OR embolism OR anticoagulation OR Embolus OR prophylaxis)).ResultsThe Top 100 cited articles included in the final list generated a total of 21,099 citations. The highest cited article was Prevention of venous thromboembolism by Geerts et al. published in Chest, which had a total of 2802 on WoS, and a calculated citation density of 215.54 of citations/years since publication. Comparing the overall citation against the year of publication there was a slight positive trend favoring more recent publications (R-value: 0.142; adjusted R-squared: 0.01; p = 0.16). Analysis of an articles Level of Evidence (LOE), 17 were grade with a level of I.ConclusionsOrthopaedic thromboprophylaxis is an ever-changing field that is at the forefront of orthopaedic literature. The significant trend favoring high quality research within orthopaedic thromboprophylaxis demonstrates the importance of this topic and there was a need for a guide to best understand the evolution of DVT prophylaxis.     

The 100 top-cited articles in diabetic kidney disease: a bibliometric analysis

BackgroundTremendous scientific researches have been conducted in the field of diabetic kidney disease (DKD), while few bibliometric analyses have been performed. We aim to identify 100 top-cited published articles about DKD and analyze their main characteristics quantitatively.MethodsWeb of Science was searched with the term ‘diabetic kidney disease’ OR ‘diabetic nephropathy’ to identify the top 100 most cited articles. For articles meeting the predefined criteria, the following data were extracted and analyzed: citation ranking, publication year, publication journal, journal impact factor, country and institution, authors, study type, and keywords.ResultsThe highest number of citations was 4753 times. The median average citations per year was 21.8 (IQR, 16.6–33.0). Most articles focused on the pathogenesis and treatment. These articles were published in 25 different journals and the Journal of the American Society of Nephrology published the greatest number (20%). Forty-three articles (43%) originated from the United States. The University of Groningen was the leading institute, contributing five top-cited articles. The most frequent first author was de Zeeuw (n = 4), followed by Parving (n = 3). There was no correlation between the average citations and the number of authors, the number of institutes, or the number of funds, respectively. Experimental animal study was the research type most frequently conducted (n = 30), followed by observational study (n = 24). Keyword analysis revealed transforming growth factor-β, oxidative stress, proteinuria, and renin–angiotensin–aldosterone system interruption are classic research topics. Sodium-glucose cotransporter 2 inhibitors, glucagon-like peptide 1 receptor agonists, and anti-inflammatory agents are the emerging trends of DKD.ConclusionsThis bibliometric analysis helps in identifying the milestones, inadequacies, classic hotspots, and emerging trends of DKD. Pathogenesis and treatment are core themes in DKD research, while high-quality articles on the prediction and biomarker are insufficient. New analyzing metrics are needed to assess the actual impact of these top-cited articles on clinical practice.     

Femoroacetabular Impingement and Labral Tear: From the Most Highly Cited Articles to Research Interests

ObjectiveTo highlight the characteristics of the most highly cited articles and propose the research interests over the past decades in the field of femoroacetabular impingement (FAI) and labral tear.MethodsThe ISI Web of Science database (Clarivate Analytics, New York, the United States) was utilized for the identification of articles on 15 December 2020. FAI and labral tear‐related articles (1138 articles) were retrieved, of which the 100 most‐cited articles (top 100) were identified. Subsequent analysis included citation density (citations/article age), authorship, institution, journal, geographic distribution, level of evidence, and theme.ResultsThe number of citations per article ranged from 66 to 1189 with a mean of 163.31. The majority of articles were published in the United States (all articles/top 100 = 655/57) and Switzerland (85/22). University of Bern (n = 10) was the most prolific institution. The journal with the most of articles was Arthroscopy: The Journal of Arthroscopic and Related Surgery. The most prolific coauthor (all articles) or first authors (top 100) was Domb (n = 109) and Philippon (n = 6), respectively. The evidence with the most articles is level IV (n = 41). The top three most popular topics of research article were outcomes of surgery (n = 23), imaging diagnosis (n = 18), and comparison of surgery (n = 8). The top four most prevalent themes of review were labral tears (n = 3), FAI (n = 3), comparison of surgery imaging diagnosis, and outcomes of surgery (both n = 2). Six keywords with the newest average publication year, including FAI syndrome (average publication year = 2019.50), patient‐reported outcomes (2019.43), femoroplasty (2018.60), clinical outcomes (2018.17), borderline dysplasia (2018.00), and capsule (2018.00). Five keywords with the highest average citations, including outcome (average citations = 88.50), alpha angle (58.00), complications (55.86), revision hip arthroscopy (49.00), and systematic review (46.14).ConclusionsOutcomes research is the most popular research interest and patient‐reported outcome instruments might be further and widely used in the emerging articles in the near future. The field of FAI and labral tear has shown an obvious trend of development and is steadily evolving. It could be predicted that there will be an increasing number of publications in the following years, with the United States and Switzerland maintaining leadership in this field.     

The 50 Highest Cited Papers in Hip and Knee Arthroplasty

The 50 highest cited articles related to hip and knee arthroplasty were searched in Thomson ISI Web of Science®. The 50 highest cited articles had up to 2495 citations. The top 10 papers according to absolute number were cited 580 times at least. Most papers were published in the Journal of Bone and Joint Surgery American Volume (n = 22). Eight countries contributed to the list with most contributions from the United States (n = 30). The majority of papers were published since 1990 (n = 27). Studies focusing on the clinical outcome of hip arthroplasty dominate the literature in orthopedic arthroplasty in respect to absolute citations numbers. In the last decade however, papers on perioperative management have been published that show a high citation frequency.     

Trends in rotator cuff surgery: Research through the decades

IntroductionThe aim of this study is to analyse the most cited articles in rotator cuff surgery and identify trends in topics by decade to see which areas may still need further investigationMethodsJournal Citation Index was searched to find articles using the search terms pertaining to “rotator cuff repair”. All articles were ranked according to most cited, and then further analysed to find most cited articles in each decade. Articles were grouped into topics to find themes for each decade.ResultsAll the most cited articles were published in 6 orthopaedic journals. Only 4 of the top 30 citations provided level I evidence. Each decade’s most cited articles seemed to fit into a broad topic, with platelet-rich plasma and biologic augmentation being prominent in the last decade.ConclusionThere are still many unanswered questions in rotator cuff surgery, but this may be because success of certain treatment options are highly dependent on patient selection. Despite growing numbers of articles being published on rotator cuff repairs, the level of evidence remains low. Larger, collaborative projects may help in answering the common dilemmas that still face shoulder surgeons.     

The 50 Most-cited Articles in Orthopaedic Surgery From Mainland China

Background

Citation analysis has been widely used to evaluate the impact of articles in medical and surgical specialties. Although China is the most populous country in the world, and although more than 50,000 orthopaedic surgeons practice there, to our knowledge no formal citation analysis of Chinese orthopaedic articles has been performed.

Questions/purposes

We identified the 50 most-cited orthopaedic articles from mainland China and evaluated these articles in terms of their language of publication, source journals, and topics.

Methods

Science Citation Index Expanded was searched in July 31, 2014 for citations of articles published in 70 selected journals since the inception of the database. The 50 most-cited orthopaedic articles originating in mainland China were identified. Basic information, including title, authors, year of publication, article type, journal in which the work was published, city, institution, number of citations, decade published, and topic or subspecialty of the research were recorded.

Results

The number of citations for the top 50 papers ranged from 181 to 31 (mean, 52). These articles were published between 1981 and 2010. The decade of 2000 to 2009 was the most prolific, with 36 of the top 50 articles published during this time. All articles were written in English and they were published in a total of 16 journals. The journal Spine published the largest number of articles (12), followed by Clinical Orthopaedics and Related Research^® (seven). The journal Lancet had the highest impact factor (39.207 for 2013) among any of the journals that published articles we identified. The top 50 articles originated mainly from Beijing (16) and Shanghai (12), with basic research being the focus of the majority (27 of 50; 54%); the remaining were clinical studies. Bone was the most-investigated topic in basic research; the spine was the most-common topic among the identified clinical studies.

Conclusions

The 50 most-cited articles that we identified should be considered influential, although a large gap remains between mainland China and the global orthopaedic community in terms of citations per article. Nevertheless, insofar as the most-recent decade of our survey generated the most articles in this top-50 list, we would characterize mainland China’s effect on musculoskeletal research as increasing, and as funding increases to programs in mainland China, we anticipate this trend will continue in the future.     

Association of scientific and nonscientific factors to citation rates of articles of renowned orthopedic journals

Purpose

The physician often relies on the prestige of a journal to identify the most relevant articles to be read in his field. This investigation studied associations of scientific and nonscientific criteria with the citation frequency of articles in two top-ranked international orthopedic journals.

Methods

The 100 most (mean, 88 citations/5 years for cases) and 100 least (mean, two citations/5 years for controls) cited articles published between 2000 and 2004 in the Journal of Bone and Joint Surgery and the Bone & Joint Journal (formerly known as JBJS (Br)), two of the most distributed general orthopedic journals, were identified. The association of scientific and nonscientific factors on their citation rate was quantified.

Results

Randomized controlled trials, as well as multicenter studies with large sample sizes, were significantly more frequent in the high citation rate group. The unadjusted odds of a highly cited article to be supported by industry were 2.8 (95 % confidence interval 1.5, 5.6; p?<?0.05) if compared with a lowly cited article.

Conclusion

Beside scientific factors, nonscientific factors such as industrial support seem associated to the citation rate of published articles. This, together with publication bias, questions whether scientific facts reach the readers in a balanced fashion. Level of Evidence 3
