A global bibliometric and visualized analysis of gait analysis and artificial intelligence research from 1992 to 2022

Gait is an important basic function of human beings and an integral part of life. Many mental and physical abnormalities can cause noticeable differences in a person's gait. Abnormal gait can lead to serious consequences such as falls, limited mobility and reduced life satisfaction. Gait analysis, which includes joint kinematics, kinetics, and dynamic Electromyography (EMG) data, is now recognized as a clinically useful tool that can provide both quantifiable and qualitative information on performance to aid in treatment planning and evaluate its outcome. With the assistance of new artificial intelligence (AI) technology, the traditional medical environment has undergone great changes. AI has the potential to reshape medicine, making gait analysis more accurate, efficient and accessible. In this study, we analyzed basic information about gait analysis and AI articles that met inclusion criteria in the WoS Core Collection database from 1992-2022, and the VosViewer software was used for web visualization and keyword analysis. Through bibliometric and visual analysis, this article systematically introduces the research status of gait analysis and AI. We introduce the application of artificial intelligence in clinical gait analysis, which affects the identification and management of gait abnormalities found in various diseases. Machine learning (ML) and artificial neural networks (ANNs) are the most often utilized AI methods in gait analysis. By comparing the predictive capability of different AI algorithms in published studies, we evaluate their potential for gait analysis in different situations. Furthermore, the current challenges and future directions of gait analysis and AI research are discussed, which will also provide valuable reference information for investors in this field.

A comprehensive overview of psoriatic research over the past 20 years: machine learning-based bibliometric analysis

Background

The surge in the number of publications on psoriasis has posed significant challenges for researchers in effectively managing the vast amount of information. However, due to the lack of tools to process metadata, no comprehensive bibliometric analysis has been conducted.

Objectives

This study is to evaluate the trends and current hotspots of psoriatic research from a macroscopic perspective through a bibliometric analysis assisted by machine learning based semantic analysis.

Methods

Publications indexed under the Medical Subject Headings (MeSH) term "Psoriasis" from 2003 to 2022 were extracted from PubMed. The generative statistical algorithm latent Dirichlet allocation (LDA) was applied to identify specific topics and trends based on abstracts. The unsupervised Louvain algorithm was used to establish a network identifying relationships between topics.

Results

A total of 28,178 publications were identified. The publications were derived from 176 countries, with United States, China, and Italy being the top three countries. For the term "psoriasis", 9,183 MeSH terms appeared 337,545 times. Among them, MeSH term "Severity of illness index", "Treatment outcome", "Dermatologic agents" occur most frequently. A total of 21,928 publications were included in LDA algorithm, which identified three main areas and 50 branched topics, with "Molecular pathogenesis", "Clinical trials", and "Skin inflammation" being the most increased topics. LDA networks identified "Skin inflammation" was tightly associated with "Molecular pathogenesis" and "Biological agents". "Nail psoriasis" and "Epidemiological study" have presented as new research hotspots, and attention on topics of comorbidities, including "Cardiovascular comorbidities", "Psoriatic arthritis", "Obesity" and "Psychological disorders" have increased gradually.

Conclusions

Research on psoriasis is flourishing, with molecular pathogenesis, skin inflammation, and clinical trials being the current hotspots. The strong association between skin inflammation and biologic agents indicated the effective translation between basic research and clinical application in psoriasis. Besides, nail psoriasis, epidemiological study and comorbidities of psoriasis also draw increased attention.

Dermatology Publications in Saudi Arabia: A Fast-Growing Pattern

Bibliometric analysis provides an accurate report of the quantity and quality of research affiliated with a specific country. We aimed to use bibliometric analysis to evaluate previously published dermatology-related studies from Saudi Arabia (SA). We conducted a retrospective, cross-sectional bibliometric analysis using the Web of Science (WoS) and Scopus databases to retrieve all SA-affiliated dermatology research from the databases' respective dates of conception to July 9, 2021. The number of publications was determined by the total number of articles, the number of times an article was cited, publishing journals, and affiliated institutions. The Hirsch index (h-index) was used to describe the quality of the articles. In total, SA-affiliated dermatologists published 1,319 articles in WoS and Scopus. Approximately half (n=603) of these articles were published in the past six years. According to WoS, the total number of citations was 9,285 with more than half of all citations also occurring in the past six years. The International Journal of Dermatology was associated with the highest number of publications, followed by the Journal of the American Academy of Dermatology. SA had the second-highest number of publications in the Arab world. Our area has recently experienced rapid growth in dermatology publications. We encourage the use of data from the current study to identify the strengths and weaknesses of such publications, to direct researchers and funds to enhance the national growth of dermatology research, and to conduct periodic bibliometric analyses with the aim of assessing the quality and quantity of SA-affiliated publications over time.

Predicting the number of article citations on the topic of pemphigus vulgaris with the 100 top-cited articles since 2011: A protocol for systematic review and meta-analysis

BACKGROUND

Pemphigus vulgaris (PV) is a rare autoimmune blistering disease characterized by intraepithelial and mucocutaneous blister formation and erosion. Numerous articles related to PV have been published. However, which articles have a tremendous influence is still unknown, and factors affecting article citation numbers remain unclear. We aimed to visualize the prominent entities using the top 100 most-cited articles on the topic of PV (T100PV), and investigate whether medical subject headings (i.e., MeSH terms) can be used to predict article citations.

METHODS

By searching the PubMed Central (PMC) database, the T100PV abstracts since 2011 were downloaded. Citation analysis was performed to compare the dominant entities in article topics, authors, and research institutes using social network analysis (SNA) and Kano diagrams. We examined the MeSH prediction power against article citations using correlation coefficients (CCs).

RESULTS

The most cited article (125 times) was authored by Ellebrecht from the University of Pennsylvania in the US. The most productive countries were Germany (28%) and the US (25%). Most articles were published in J Invest Dermatol (16%) and Br J Dermatol (10%). Kasperkiewicz (Germany) and the Normandie University (France) were the most cited authors and research institutes, respectively. The most frequently occurred MeSH terms were administration and dosage, immunology, and metabolism. MeSH terms were evident in the prediction power on the number of article citations (F = 19.77; P < .001).

CONCLUSION

A breakthrough was achieved by developing dashboards to display the T100PV. MeSH terms can be used to predict the T100PV citations. These T100PV visualizations can be applied in future studies.

BACKGROUND

Due to the increasing number of joint arthroplasty operations, surgeons have begun to devote more attention to the problem of periprosthetic osteolysis. In recent years, numerous studies have focussed on periprosthetic osteolysis, but there have been no relevant bibliometric studies.

METHODS

We searched the Web of Science database for relevant articles concerning periprosthetic osteolysis published from 1965 to 2021. The following data were extracted: authors' name, article title, publication journal, impact factor (IF) of the journal in the publication year, keywords, topic of the article, publication country/region, the sum of times cited, H-index and funding sources. VOSviewer and Excel 2019 were used to conduct the bibliometric study and visualise the analysis.

RESULTS

A total of 1255 publications were included. In all selected articles, "orthopaedics" became the dominant topic (662 of 1255, 52.75%). The most productive years were 2018 and 2019, with a total of 83 publications. The Journal of Arthroplasty published the most articles on periprosthetic osteolysis (110 publications). The United States of America published the most articles (525, 41.83%). The latest keywords "continuous intramedullary infusion", "erythromycin", "autophagy", "bone-resorbing cells" and "proinflammatory cytokines" both appeared in five articles in 2017.

CONCLUSION

This bibliometric study showed that there is a growing trend in published articles related to periprosthetic osteolysis. Journal of Arthroplasty was the top productive journal on periprosthetic osteolysis. The United States of America dominates studies of periprosthetic osteolysis. "Continuous intramedullary infusion", "erythromycin", "autophagy", "bone-resorbing cells" and "proinflammatory cytokines" may be new research hotspots in the field of periprosthetic osteolysis.

A cross-sectional bibliometric analysis was conducted in January 2021 by using Boolean search terms in the Scopus and the Web of Science databases. The 50 top-cited articles that met the inclusion criteria were ranked and evaluated for several characteristics, including year of publication, country of origin, authorship, publishing journal, topic categories, publishing type, and level of evidence. The median number of citations per article in the list was 442 (interquartile range [IQR], 320-520), with a median of 21.8 citations (IQR, 16.5-34.5) per year since publication. The publication years ranged from 1986 to 2017, with 1998 accounting for the greatest number of studies (n = 7). The citation classics were published in 20 journals and originated from institutions in 9 countries. The majority of the studies were clinical, of which expert opinion/review with Level V evidence and clinical studies with Levels I and II evidence comprised the greater proportion in the list. This study provides useful insights into the history and development of DFU research. The top-cited list may serve as a quick reference for education curriculums and clinical practice, in addition to providing a foundation for further studies on this topic.

Ankylosing spondylitis rehabilitation publications and the global productivity: a Web of Science-based bibliometric analysis (2000-2019)

Rehabilitation programs have an important place in the treatment of ankylosing spondylitis (AS), but there is no comprehensive bibliometric research that assesses publications on AS rehabilitation in a holistic way. The aim of this study was to investigate the quantity and quality of articles related to AS rehabilitation and to reveal the features of global productivity in this topic. This bibliometric study was conducted utilizing the Web of Science (WoS) database with the keywords 'ankylosing spondylitis rehabilitation', 'ankylosing spondylitis exercise', 'ankylosing spondylitis physical therapy' and 'ankylosing spondylitis physiotherapy'. The number of articles, citations, and main active countries were determined and trend analyses were performed. A total of 792 articles were reviewed. The articles originated from 51 different countries, 22 of which met the main active country criteria. A significant increase trend was detected in the number of articles between 2000 and 2019 (p < 0.001). The five most productive countries were Germany (n = 111; 14.02%), Turkey (n = 98; 12.37%), the United States (n = 71; 8.96%), the United Kingdom (n = 53; 6.69%) and the Netherlands (n = 53; 6.69%). The highest values in number of articles per million population were calculated in Norway, the Netherlands and Austria, respectively. In the analysis according to GDP, Norway, the Netherlands and Turkey were ranked as the first three. The top three countries for the average citation count were France, Netherlands and Germany. This bibliometric study can be considered as an assessment and summary of worldwide scientific production on AS rehabilitation. The data demonstrate an increasing trend in research productivity since 2000. European countries were seen to be at the forefront both quantitatively and qualitatively in this area.

Trends in the Use of Sphingosine 1 Phosphate in Age-Related Diseases: A Scientometric Research Study (1992-2020)

OBJECTIVES

This study was designed to explore the intellectual landscape of research into the application of sphingosine 1 phosphate (S1P) in age-related diseases and to identify thematic development trends and research frontiers in this area.

METHODS

Scientometric research was conducted by analyzing bibliographic records retrieved from the Web of Science (WOS) Sci-Expanded Database dated between 1900 and 2020. Countries, institutions, authors, keyword occurrence analysis, and cooperation network analysis were performed using the CiteSpace and VOSviewer software.

RESULTS

A total of 348 valid records were included in the final dataset, and the number of publications and the frequency of citations have grown rapidly over the last ten years. The USA (n = 175), China (n = 42), and Germany (n = 37) were the three largest contributors to the global publications on S1P and aging, while the Medical University of South Carolina (n = 15), University of California, San Francisco (n = 13), and University of Toronto (n = 13) were the leading institutions in this field. Analysis showed that early studies primarily focused on the mechanism of S1P intervention in AD. While S1P and its relevant metabolites have remained a long-term active area of research, recent studies have focused more on interventions aimed at improving retinal degeneration, cardiomyopathy, multiple sclerosis, and diabetes, among others.

CONCLUSIONS

It is worth mentioning that this manuscript is the first to describe any bibliometric analysis of S1P and its application in age-related interventions. This study includes a discussion of the (1) historical overview of the topic; (2) main contributors: journals, countries, institutes, funding agencies, and authors; (3) collaboration between institutes and authors; (4) research hot spots and zones; and 5) research trends and frontiers. This will enable scholars to understand the current status of S1P research in age-related diseases.

The 100 Top-Cited Studies on Dyslexia Research: A Bibliometric Analysis

Background: Citation analysis is a type of quantitative and bibliometric analytic method designed to rank papers based on their citation counts. Over the last few decades, the research on dyslexia has made some progress which helps us to assess this disease, but a citation analysis on dyslexia that reflects these advances is lacking. Methods: A retrospective bibliometric analysis was performed using the Web of Science Core Collection database. The 100 top-cited studies on dyslexia were retrieved after reviewing abstracts or full-texts to May 20th, 2021. Data from the 100 top-cited studies were subsequently extracted and analyzed. Results: The 100 top-cited studies on dyslexia were cited between 245 to 1,456 times, with a median citation count of 345. These studies were published in 50 different journals, with the "Proceedings of the National Academy of Sciences of the United States of America" having published the most (n = 10). The studies were published between 1973 and 2012 and the most prolific year in terms of number of publications was 2000. Eleven countries contributed to the 100 top-cited studies, and nearly 75% articles were either from the USA (n = 53) or United Kingdom (n = 21). Eighteen researchers published at least two different studies of the 100 top-cited list as the first author. Furthermore, 71 studies were published as an original research article, 28 studies were review articles, and one study was published as an editorial material. Finally, "Psychology" was the most frequent study category. Conclusions: This analysis provides a better understanding on dyslexia and may help doctors, researchers, and stakeholders to achieve a more comprehensive understanding of classic studies, new discoveries, and trends regarding this research field, thus promoting ideas for future investigation.
