The top 2,000 cited articles in critical care medicine: a bibliometric analysis

Brand and addiction: A network analysis of scientific literature

OBJECTIVE

The paper conducts a network analysis of the fragmented literature on brand and addiction.

METHOD

A thematic map, thematic evolution, word cloud, co-citation analysis, and cooperation networks were utilized to identify brand addiction study trends and topics.

RESULTS

The data show that marketing and psychiatry have interdisciplinary groupings and multidisciplinary publications. These groups reflect societal changes, particularly the shift from traditional to digital challenges. Fast food addiction is different from alcohol and cigarette addictions due to its ease and extensive marketing. The decline in internet and gambling addiction suggests a shift in priorities.

CONCLUSIONS

This research helps researchers, policymakers, and practitioners in addiction prevention and intervention. The study also understands brand addiction and its effects on psychology, psychiatry, and management by providing insights into emerging topics, thematic maps and evolution of studies, collaboration opportunities, geographical distribution of studies, and more.

A bibliometric analysis of brachial plexus injury from 1980 to 2022

Background

Brachial plexus injury is a common severe peripheral nerve injury with high disability. At present, the bibliometric analysis of brachial plexus injury is basically unknown.

Methods

This article analyzes the data retrieved to the web of science and uses the R language (version 4.2), Citespace (version 6.1.R3 Advanced), Vosviewer (Lei deng university) to make a scientific map. Specifically, we analyze the main publication countries, institutions, journals where the article is published, and the cooperative relationship between different institutions, the relationship between authors, main research directions in this field, and current research hotspots.

Results

From 1980 to 2022, the total number of publications is 1542. In terms of countries where articles were published, 551 records were published in the United States, accounting for 35% of the total. With 74 articles, Fudan University ranks first in the world in terms of the number of articles issued by the institution, followed by 72 articles from Mayo Clinic. The magazine with the largest number of articles is JOURNAL OF HAND SURGERY-AMERICAN VOLUME, which has published 87 articles in total. GU YD (Gu Yu-Dong) team (Fudan University) and spinner RJ (Robert J Spinner) team (Mayo clinic) are in a leading position in this field. Nerve transfer and nerve reconstruction have been a hot topic of brachial plexus injury. "Spinal nerve root repair and reimplantation of avulsed ventral roots into the spinal cord after brachial plexus injury" has the strongest citation bursts.

Conclusion

Research on brachial plexus injury shows a trend of increasing heat. At present, there is a lack of communication and cooperation between scholars from different countries. Nerve transfer and nerve reconstruction are the current and future research directions in the treatment of brachial plexus injury.

Trends in major intensive care medicine journals: A machine learning approach

PURPOSE

Intensive care medicine (ICM) has the particularity of being a multidisciplinary specialty and its literature reflects this multidisciplinarity. However, the proportion of each field in this literature and its trend dynamics are not known. The objective of this study was to analyze the ICM literature, extract latent topics and search for the presence of research trends.

MATERIAL AND METHODS

Abstracts of original articles from the top ICM journals, from their inception until December 31st, 2019, were included. This corpus was fed into a structural topic modeling algorithm to extract latent semantic topics. The temporal distribution was then analyzed and the presence of trends was searched by Mann-Kendall trends tests.

RESULTS

Finally, 49,276 articles from 10 journals were included. After topic modeling analysis and experts' feedback, 124 research topics were selected and labeled. Topics were categorized into 19 categories, the most represented being respiratory, fundamental and neurological research. Increasing trends were observed for research on mechanical ventilation and decreasing trends for cardiopulmonary resuscitation.

CONCLUSIONS

This study reviewed all articles from major ICM journals in a comprehensive way. It provides a better understanding of ICM research landscape by analyzing the temporal evolution of latent research topics in the ICM literature.

Artificial Intelligence in Intensive Care Medicine: Bibliometric Analysis

Background

Interest in critical care–related artificial intelligence (AI) research is growing rapidly. However, the literature is still lacking in comprehensive bibliometric studies that measure and analyze scientific publications globally.

Objective

The objective of this study was to assess the global research trends in AI in intensive care medicine based on publication outputs, citations, coauthorships between nations, and co-occurrences of author keywords.

Methods

A total of 3619 documents published until March 2022 were retrieved from the Scopus database. After selecting the document type as articles, the titles and abstracts were checked for eligibility. In the final bibliometric study using VOSviewer, 1198 papers were included. The growth rate of publications, preferred journals, leading research countries, international collaborations, and top institutions were computed.

Results

The number of publications increased steeply between 2018 and 2022, accounting for 72.53% (869/1198) of all the included papers. The United States and China contributed to approximately 55.17% (661/1198) of the total publications. Of the 15 most productive institutions, 9 were among the top 100 universities worldwide. Detecting clinical deterioration, monitoring, predicting disease progression, mortality, prognosis, and classifying disease phenotypes or subtypes were some of the research hot spots for AI in patients who are critically ill. Neural networks, decision support systems, machine learning, and deep learning were all commonly used AI technologies.

Conclusions

This study highlights popular areas in AI research aimed at improving health care in intensive care units, offers a comprehensive look at the research trend in AI application in the intensive care unit, and provides an insight into potential collaboration and prospects for future research. The 30 articles that received the most citations were listed in detail. For AI-based clinical research to be sufficiently convincing for routine critical care practice, collaborative research efforts are needed to increase the maturity and robustness of AI-driven models.

Impactful publications of critical care medicine research in China: A bibliometric analysis

BACKGROUND

Although publications have been increasing rapidly, the research quality has yet to improve in the field of critical care medicine (CCM) in China. This study aimed at investigating the current status of and the influential factors for impactful publications in CCM research by Chinese authors.

METHODS

Publications by authors with the affiliation of critical care medicine department or intensive care unit (CCM/ICU) in Chinese as well as American hospitals from 2001 to 2020 were retrieved from the Web of Science Core Collection (WoSCC) database for this bibliometric analysis. Moreover, statistical analyses to test factors affecting impactful publications by Chinese authors were performed.

RESULTS

Of 13,487 articles retrieved by this search strategy, 6,622 were published by Chinese authors as first or corresponding authors. The annual publications by Chinese authors have been rapidly increasing from 2001 to 2020, and so did the citations to these articles. However, the proportion in the world of publications by Chinese authors was much less than that by American authors each year [M (IQR): 1.85 (9.592) vs. 27.77 (7.3), p < 0.001]. In addition, impactful articles were significantly less published by Chinese than by American authors, including articles either in journals with a high impact factor (p < 0.001) or in the top 10 journals in the field of CCM (5.4 vs 13.4%, p < 0.001), and articles with high citation frequency as well (p < 0.001). Moreover, the percentage of impactful publications by Chinese authors was likely associated with academic background and regions of the author's affiliations, funds support, public health events of COVID-19, and collaboration between authors.

CONCLUSION

Our results demonstrated that CCM research in China grew rapidly in the recent 20 years. However, the impactful publications remained limited, largely owing to the shortage of comprehensive research training, inactive collaboration, and underfunded CCM research.

Publications in Pediatric Epilepsy: Using Bibliometrics to Determine Readings in the Field

Bibliometrics and citation analysis are popular forms of analyzing medical literature based on article impact as determined by the number of citations an article has received from other publications. Many bibliometric studies published within the past 10 years have assembled lists of highly cited papers, top 100 papers, or citation classics of specialties, subspecialties, and specific morbidities. For pediatric epilepsy, there is only 1 study that bibliometrically examines articles in this subspecialty. Although bibliometrics generally examines trends in the literature, we used bibliometrics as a methodology for determining a core set of pediatric epilepsy articles with the highest impact (ie, citation count) that could be used as an introductory reading list for residents, fellows, and early career epileptologists. Therefore, we searched Web of Science to identify the 100 top-cited pediatric epilepsy articles and develop 10 topic areas into which we sorted each article. These recommended articles could be used as essential readings for pediatric epilepsy.

Analysis of the Research Hotspot of Drug Treatment of Tuberculosis: A Bibliometric Based on the Top 50 Cited Literatures

Objective

The objective of the current study was to analyze the research hotspot of drug treatment for tuberculosis via top literatures.

Materials and Methods

A retrospective analysis was performed on June 7th, 2021. Literatures were searched on the Web of Science Core Collection to identify the top 50 cited literatures related to drug treatment of tuberculosis. The characteristics of the literatures were identified. The outcomes included authorship, journal, study type, year of publication, and institution. Cooccurrence network analysis and visualization were conducted using the VOS viewer (Version 1.6.16; Leiden University, Leiden, The Netherlands).

Results

The top 50 cited literatures were cited 308 to 2689 times and were published between 1982 and 2014. The most studied drugs were the first-line drugs such as isoniazid and rifampicin (n = 22), and drug-resistant tuberculosis was most frequently reported (n = 16). They were published in 18 journals, and the New England Journal of Medicine published the most literatures (n = 18), followed by the American Journal of Respiratory and Critical Care Medicine (n = 7), and the Lancet (n = 6). The authors were from 13 countries, and the authors from the USA published most of the literatures (n = 30), while authors from other countries published less than five literatures. The CDC in the USA (n = 4), the World Health Organization (WHO) (n = 3), and the American Philosophical Society (n = 3) were the leading institutions, and only two authors published at least two top-cited literatures as first authors.

Conclusions

This study provides insights into the development and most important literatures on drug therapy for tuberculosis and evidence for future research on tuberculosis treatment.

A bibliometric analysis of paramedicine publications using the Scopus database: 2010-2019

BACKGROUND

Paramedicine is an evolving profession undergoing increases in scholarly activity and peer-reviewed publications. This study aims to complete the first extensive bibliometric examination of the worldwide paramedicine literature.

METHOD

Scopus was utilised to search for paramedicine-based articles published in peer-reviewed journals between 2010 and 2019 inclusive. The included articles were examined for citation count, journal, journal quartile, country of origin, university affiliation, collaboration, and topic.

RESULTS

Paramedicine-based publications have steadily increased and are predominantly published in prehospital or emergency healthcare journals. The majority of highly cited authors were located in Australia; however, only one of these authors was identified as a paramedic. Monash University (Australia) was the most productive institution (11.7% of total articles) and collaboration was mostly within national boundaries (53.2%).

CONCLUSION

This study demonstrates the progressive increase in paramedic scholarly activity over the past decade. Although a large number of articles originate from two countries (Australia and the USA) and one university, numerous nations and institutions are contributing to this body of knowledge. The growing literature base is indicative of the evolution of paramedicine; however, the high level of non-paramedic authors suggests the opportunity for further scholarly development within the paramedic discipline.

Top 100 cited paramedicine papers: A bibliometric study

OBJECTIVE

Understanding the impact different journal articles have in any academic field is important - particularly in emerging professions. A bibliometric analysis like this does not yet exist for paramedicine, despite the rapid increase in its primary literature. The objective of the present study was to identify and analyse the 100 top-cited articles about paramedicine.

METHODS

We searched the Scopus database in August 2020 for studies relating to paramedicine. After screening titles and abstracts, we extracted the citation count, journal name, publication year, and country of origin. We manually assessed whether the study was clinical or not, noted the sex of the authors, the profession of first and last authors and the study design used.

RESULTS

The median citation count for the top 100 papers in paramedicine was 58 (interquartile range 46-84 citations). The articles were published across 48 different journals, with Resuscitation and Prehospital Emergency Care being the two most frequent. The top-cited paramedic papers originated from 16 different countries and were written predominantly by medical doctors. Three quarters (73%) of the studies had a clinical focus, and a quarter (26%) were randomised controlled trials.

CONCLUSIONS

The evolution of paramedicine towards professionalism is backed up by the growth of its own body of knowledge. This analysis of the 100 most cited studies in paramedicine is the first of its kind and highlights that paramedicine articles have a high citation count and are published across numerous journals, but with a relative lack of contribution from paramedic practitioners and female researchers.

Worldwide scientific productions with immunotherapy of sepsis: a bibliometric analysis

Background

Sepsis represents a significant healthcare problem worldwide and causes a high number of deaths every year but remains to be fully understood. During and after sepsis, the host immune response is complex and involves an initial excessive host inflammatory response to infection that is closely related to tissue damage and leads to organ failure. Over the past three decades, immunotherapy for sepsis has vastly improved, but in this area, the most influential articles, journals, authors, and countries have not yet been completely summarized and analyzed.

Objective

Performed a bibliometric analysis on all the articles concerning immunotherapy for sepsis from 1962 to 2019 was our objective, and we also explored the potential correlations between publications of different countries and their gross domestic product (GDP).

Methods

All articles about immunotherapy for sepsis were extracted from the Scopus database and analyzed. We also retrieved GDP data from all the countries that have published information from the World Bank.

Results

In summary, we have retrieved 1,483 related articles from the Scopus database starting from the first publication on immunotherapy for sepsis in 1962 through March 16, 2019. Over the past decade, the number of the articles published has increased year by year to reach 866 in total, which accounts for about 58% of all publications, with 2017 being the most prolific year when 179 articles were published. The US published 604 articles (41%), followed by China (n = 163, 11%), and Germany (n = 158, 11%). In terms of publishing media, the journal that published the highest number of the articles was Journal of Critical Care Medicine with 65 articles (4%), followed by Shock with 55 articles (4%), and Critical Care with 35 articles (2%). There was a strong correlation between the GDP of the different countries and their publication numbers (r = 0.811, P < 0.001).

Conclusions

Our present study analyzed all types of articles concerning immunotherapy for sepsis over the past 57 years and countries with high GDP tends to make more contributions to the medical field of this field. In the meantime, these studies highlight the importance of immunotherapy in the treatment of sepsis patients. The recognition of the historical status and development trend of this field can promote inter-agency cooperation, guide future research, and ultimately provide the basis for clinical practice guidelines.

Highly visible sepsis publications from 2012 to 2017: Analysis and comparison of altmetrics and bibliometrics

PURPOSE

We sought to delineate highly visible publications related to sepsis. Within these subsets, elements of altmetrics performance, including mentions on Twitter, and the correlation between altmetrics and conventional citation counts were ascertained.

MATERIALS AND METHODS

Three subsets of sepsis publications from 2012 to 2017 were synthesized by the overall Altmetric.com attention score, number of mentions by unique Twitter users, and conventional citation counts. For these subsets, geolocated Twitter activity was plotted on a choropleth, the lag between publication date and altmetrics mentions was characterized, and correlations were examined between altmetrics performance and normalized conventional citation counts.

RESULTS

Of 57,152 PubMed query results, Altmetric.com data was available for 28,344 (49.6%). The top 50 publications by Altmetric.com attention score and Twitter attention represented a mix of original research and other types of work, garnering attention from Twitter users in 143 countries that was highly contemporaneous with publication. Altmetrics performance and conventional citation counts were poorly correlated.

CONCLUSIONS

While unreliable to gauge impact or future citation potential, altmetrics may be valuable for parties who wish to detect and drive public awareness of research findings and may enable researchers to dynamically explore the reach of their work in novel dimensions.
