“…Publication success is measured by the number of publications (scientific output) and the number of citations (scientific impact). Both can be estimated by the specified Hirsch index (h-index) [3, 4]. This study describes the development of a scientific community over a long period of time and asks the question of the best parameter for predicting later scientific success.…”

BackgroundThe consistent focus of ‘Advances in Neuroblastoma Research’ congresses on the topic neuroblastoma sets it as a model for a circumscribed scientific community.MethodsThe contributions of authors, institutions and countries to congress abstracts and their collaborations were compared to the Hirsch index (h-index) calculated from the Web of Science publication output on the topic ‘neuroblastoma’.ResultsFrom 1975 to 2016, 18 congresses were held. 8459 authors affiliated to 553 institutions of 53 countries presented 3,993 abstracts. The number of coauthors increased over the years from 2 to 7. A considerable proportion of authors, institutions and countries presented only once (53.7%/25.7%/13.2%). Authors with a high number of abstracts and with a large local network were often among those with a higher publication rate and success (R2 = 0.508 for Pearson’s correlation between weight and h-index, R2 = 0.474 for degree centrality, R2 = 0.364 for lobby-index). Closeness and betweenness centralities were less correlated (R2 = 0.127/R2 = 0.33, resp.). The institutions showed a similar impact of local interactions on publication success (degree centrality R2 = 0.417, weight R2 = 0.308), while countries demonstrated a higher correlation of betweenness centrality and h-Index (R2 = 0.704) emphasizing their brokerage role. Of 553 institutions, 520 collaborated within 13 communities and belonged to the large scientific network. 33 satellite institutions had no connections to the central network. They attended 1–4 congresses over a period of 1–16 years.ConclusionA large scientific network has been developed during the recent 42 years. Growth and interaction at congresses were correlated to publication success. Weight is suggested as a useful and simple estimate.

“…The author, Magnavita N has five articles published but has an H-index of 25. This is supported by an article that states that H-index is loosely related to the number of articles[ 19 ]. Rather, H-index is more closely associated with academic rank in certain fields[ 20 ].…”

BACKGROUND Burnout amongst radiologists is common in many different institutions and is increasing day by day. To battle burnout, we have to address the root causes already recognized in published literature. Therefore, it is crucial to examine and discern important publications. AIM To provide evidence-based data and trends related to burnout in radiologists so that researchers can work on it further and develop preventive strategies to overcome this problem. METHODS Bibliometric analysis conducted by two independent reviewers separately used Scopus Library for data extraction by using medical subject heading and International Classification of Diseases keywords. Forty-nine articles were selected for analysis after an extensive scrutiny. Statistical Package for the Social Sciences version 20 was used for analysis. Pearson correlation coefficient, Kruskal Wallis test, and Mann-Whitney U test were applied. RESULTS The most productive period with regards to the number of publications was between 2017 and 2019. A total of 160 authors contributed to the topic burnout among radiologists, with an average of 3.26 authors per paper. About 41.68% of the authors were female, whilst 35% of them were first authors. The co-citation analysis by author involved 188 cited authors, 13 of whom were cited at least 70 times. Only six out of forty-nine studies were funded by various government institutions and non-governmental organizations. CONCLUSION Current analysis casts a spotlight on important trends being witnessed in regard to the mental health of radiologists, including lack of funding for mental health research, narrowing of female vs male citation gap, as well as authorship and citation trends.

“…In specific, as shown in Table 1 , we can understand that the US has the most publications in this field with 1,641 (32.87%), followed by China 1,307 (26.18%), UK 318 (6.37%), and Germany 302 (6.05%). The h-index, a new parameter for quantifying scientific achievement proposed by Jorge Hirsch, is defined as the number of papers with citation number ≥ h ( 27 – 29 ). It was evident from the Table that the USA and China still occupied the first and second positions in the h-index.…”

Research Hotspots and Trends of Peripheral Nerve Injuries Based on Web of Science From 2017 to 2021: A Bibliometric Analysis

et al. 2022

BackgroundPeripheral nerve injury (PNI) is very common in clinical practice, which often reduces the quality of life of patients and imposes a serious medical burden on society. However, to date, there have been no bibliometric analyses of the PNI field from 2017 to 2021. This study aimed to provide a comprehensive overview of the current state of research and frontier trends in the field of PNI research from a bibliometric perspective.MethodsArticles and reviews on PNI from 2017 to 2021 were extracted from the Web of Science database. An online bibliometric platform, CiteSpace, and VOSviewer software were used to generate viewable views and perform co-occurrence analysis, co-citation analysis, and burst analysis. The quantitative indicators such as the number of publications, citation frequency, h-index, and impact factor of journals were analyzed by using the functions of “Create Citation Report” and “Journal Citation Reports” in Web of Science Database and Excel software.ResultsA total of 4,993 papers was identified. The number of annual publications in the field remained high, with an average of more than 998 publications per year. The number of citations increased year by year, with a high number of 22,272 citations in 2021. The United States and China had significant influence in the field. Johns Hopkins University, USA had a leading position in this field. JESSEN KR and JOURNAL OF NEUROSCIENCE were the most influential authors and journals in the field, respectively. Meanwhile, we found that hot topics in the field of PNI focused on dorsal root ganglion (DRG) and satellite glial cells (SGCs) for neuropathic pain relief and on combining tissue engineering techniques and controlling the repair Schwann cell phenotype to promote nerve regeneration, which are not only the focus of research now but is also forecast to be of continued focus in the future.ConclusionThis is the first study to conduct a comprehensive bibliometric analysis of publications related to PNI from 2017 to 2021, whose bibliometric results can provide a reliable source for researchers to quickly understand key information in this field and identify potential research frontiers and hot directions.
