World J Gastrointest Oncol 2025; 17:102438. [PMID: 40235868 PMCID: PMC11995354 DOI: 10.4251/wjgo.v17.i4.102438] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/18/2024] [Revised: 12/25/2024] [Accepted: 02/05/2025] [Indexed: 03/25/2025] Open
Abstract
BACKGROUND Recently, numerous studies have reported the application of nanomedicines in colorectal cancer treatment. However, no systematic bibliometric analysis has been conducted to examine the potential and mechanisms of action of nanomedicine in this context. Such an analysis may provide a comprehensive overview of the current research landscape, identify emerging trends, and highlight key areas for future investigation. AIM To describe the current global research landscape on the application of nanomedicine in colorectal cancer treatment. METHODS The Web of Science Core Collection database was searched for literature published from January 1, 2010, to August 7, 2024, focusing on the application of nanomedicine in colorectal cancer treatment. Bibliometric analysis and visualization mapping of countries, institutions, authors, keywords, references of the relevant research literature were conducted using CiteSpace (6.2R6), VOSviewer (1.6.20), and bibliometrix (based on R 4.3.2). RESULTS A total of 3598 articles were included, with a rapid increase in publication volume starting from 2010. China published the most papers on this topic, followed by the United States and India. The United States emerged as the central country in this field, and the Egyptian Knowledge Bank and Chinese Academy of Sciences were the institutions with the highest number of publications. The Chinese Academy of Sciences exhibited the highest centrality. The most prolific author was Zhang Y, whereas Siegel RL was the most cited author, and Li Y had the highest H-index. The International Journal of Nanomedicine had the most publications and Biomaterials received the most citations. Keyword co-occurrence analysis identified 11837 keywords grouped into 13 clusters with 15 high-frequency highlighted keywords. The top three keyword clusters were "0 colorectal cancer", "1 drug delivery", and "2 delivery", with the top three keywords being "nanoparticles", "colorectal cancer", and "drug delivery". CONCLUSION Research on nanomedicine for colorectal cancer has surged since 2010, focusing on "nanoparticles" and "drug delivery". Future studies should investigate nanomaterial stability and target-specific drug release.

Abstract
BACKGROUND In recent years, numerous reports have been published regarding the relationship between the gut microbiota and the tumor immune microenvironment (TIME). However, to date, no systematic study has been conducted on the relationship between gut microbiota and the TIME using bibliometric methods. AIM To describe the current global research status on the correlation between gut microbiota and the TIME, and to identify the most influential countries, research institutions, researchers, and research hotspots related to this topic. METHODS We searched for all literature related to gut microbiota and TIME published from January 1, 2014, to May 28, 2024, in the Web of Science Core Collection database. We then conducted a bibliometric analysis and created visual maps of the published literature on countries, institutions, authors, keywords, references, etc., using CiteSpace (6.2R6), VOSviewer (1.6.20), and bibliometrics (based on R 4.3.2). RESULTS In total, 491 documents were included, with a rapid increase in the number of publications starting in 2019. The country with the highest number of publications was China, followed by the United States. Germany has the highest number of citations in literature. From a centrality perspective, the United States has the highest influence in this field. The institutions with the highest number of publications were Shanghai Jiao Tong University and Zhejiang University. However, the institution with the most citations was the United States National Cancer Institute. Among authors, Professor Giorgio Trinchieri from the National Institutes of Health has the most local impact in this field. The most cited author was Fan XZ. The results of journal publications showed that the top three journals with the highest number of published papers were Frontiers in Immunology, Cancers, and Frontiers in Oncology. The three most frequently used keywords were gut microbiota, tumor microenvironment, and immunotherapy. CONCLUSION This study systematically elaborates on the research progress related to gut microbiota and TIME over the past decade. Research results indicate that the number of publications has rapidly increased since 2019, with research hotspots including "gut microbiota", "tumor microenvironment" and "immunotherapy". Exploring the effects of specific gut microbiota or derived metabolites on the behavior of immune cells in the TIME, regulating the secretion of immune molecules, and influencing immunotherapy are research hotspots and future research directions.

Abstract
In early 2023, the National Institutes of Health (NIH) implemented its Data Management and Sharing (DMS) Policy, requiring researchers to share scientific data produced with NIH funding. The policy's objective is to amplify the benefits of public investment in research by promoting the dissemination and reusability of primary data. Given this backdrop, identifying a robust methodology to assess the impact of data sharing across diverse research domains is essential. In this review, we adopted two methodological paradigms, the bottom-up and top-down strategies, and employed content analysis to pinpoint established methodologies and innovative practices within this intricate field. Although numerous author-level metrics are available to gauge the impact of data sharing, their application is still limited. Non-traditional metrics, encompassing economic (e.g., cost savings) and intangible benefits, presently appear to hold more potential for evaluating the impact of primary data sharing. Finally, we address the primary obstacles encountered by open data policies and introduce an innovative "Shared model for shared data" framework to bolster data sharing practices and refine evaluation metrics.

Abstract
Purpose: To provide a brief review of literature on the journal impact factors (JIF) and the newer research metrics being proposed or implemented.Methods: The authors performed a PubMed search of articles published in the English language on the journal impact factors. Data captured include historical perspectives, evolution, calculation, criticisms of JIF and their rebuttals, and organized efforts to address JIF issues, alternate research metrics, and future directions. Specific emphasis was laid on evaluating the criticisms, current lacunae, and the changing practice patterns.Results: One of the measures to assess the research impact of an article is the number of citations it receives. Hence, citation-based metrics are commonly used for such purposes. While editors and well-known scholars refrain from attributing article success to the journal's prominence, the same is not true for most authors. JIF is still one of the top factors when deciding on an article submission. JIF is today an acceptable objective and quantifiable measure of knowledge dissemination. However, JIF should not be used as a surrogate measure to assess an individual researcher or an individual article. The reverence to JIF in this regard needs to be questioned. While alternate metrics or altmetrics have their advantages and limitations, they nevertheless augur well an era where scientometrics are complementary to one another without undue reliance on a sole parameter.Conclusion: While there is no need to demonize the JIF, its role in the scholarly assessment should be scaled down. The over-reliance and undue hype surrounding it should be discouraged at multiple scientific levels.

Abstract
Background Journal Impact Factor (JIF) has several intrinsic flaws, which highlight its inability to adequately measure citation distributions or indicate journal quality. Despite these flaws, JIF is still widely used within the academic community, resulting in the propagation of potentially misleading information. A critical review of the usefulness of JIF is needed including an overview of the literature to identify viable alternative metrics. The objectives of this study are: (1) to assess the usefulness of JIF by compiling and comparing its advantages and disadvantages; (2) to record the differential uses of JIF within research environments; and (3) to summarize and compare viable alternative measures to JIF. Methods Three separate literature search strategies using MEDLINE and Web of Science were completed to address the three study objectives. Each search was completed in accordance with PRISMA guidelines. Results were compiled in tabular format and analyzed based on reporting frequency. Results For objective (1), 84 studies were included in qualitative analysis. It was found that the recorded advantages of JIF were outweighed by disadvantages (18 disadvantages vs. 9 advantages). For objective (2), 653 records were included in a qualitative analysis. JIF was found to be most commonly used in journal ranking (n = 653, 100%) and calculation of scientific research productivity (n = 367, 56.2%). For objective (3), 65 works were included in qualitative analysis. These articles revealed 45 alternatives, which includes 18 alternatives that improve on highly reported disadvantages of JIF. Conclusion JIF has many disadvantages and is applied beyond its original intent, leading to inaccurate information. Several metrics have been identified to improve on certain disadvantages of JIF. Integrated Impact Indicator (I3) shows great promise as an alternative to JIF. However, further scientometric analysis is needed to assess its properties.

Abstract
BACKGROUND Understanding the impact of a publication by using bibliometric indices becomes an essential activity not only for universities and research institutes but also for individual academicians. This paper aims to provide a brief review of the current bibliometric tools used by authors and editors and proposes an algorithm to assess the relevance of the most common bibliometric tools to help the researchers select the fittest journal and know the trends of published submissions by using self-evaluation. METHODS We present a narrative review answering at least two related consecutive questions triggered by the topics mentioned above. How prestigious is a journal based on its most recent bibliometrics, so authors may choose it to submit their next manuscript? And, how can they self-evaluate/understand the impact of their whole publishing scientific life? RESULTS We presented the main relevant definitions of each bibliometrics and grouped them in those oriented to evaluated journals or individuals. Also, we share with our readers our algorithm to assess journals before manuscript submission. CONCLUSIONS Since there is a journal performance market and an article performance market, each one with its patterns, an integrative use of these metrics, rather than just the impact factor alone, might represent the fairest and most legitimate approach to assess the influence and importance of an acceptable research issue, and not only a sound journal in their respective disciplines.

Abstract
ABSTRACT Objective: to discuss the use of the H-index as an indicator for the evaluation of the Nursing area researcher in the light of Thomas Kuhn's disciplinary matrix. Method: this is a reflective study, conducted between March and April 2018, which identifies the elements that underlie the H-index and criticizes it as an indicator for the evaluation of the researcher in the nursing scientific community. Results: the Nursing area is in the normal science phase and has a disciplinary matrix. It consists of theories, research methods and experiments; establishes procedures; indicates the problems to be studied and determines the scientific agenda; provides modular solutions for the scientific community; it has epistemic values that legitimize and justify the research practice. The values are of a quantitative and qualitative nature, namely: accuracy, consistency, range, simplicity, objectivity, originality and fruitfulness. The H-index cannot display the qualitative values of science. Conclusion: the quantitative and qualitative epistemic values form an amalgam, making it impossible to separate them, for it is in axiological complementarity that science is founded. From its evaluative approach with the so-called mature sciences, it is inferred that the Nursing area should consider these values for itself. The H-index is limited for the evaluation of the researcher. Care should be taken to harbor it, so as not to hinder the insertion of new candidates to be researchers into the postgraduate teaching staff, thus preventing generational sharing among peers, given that the index does not can measure the category made up by young researchers.

Abstract
OBJECT
Various bibliometric indices based on the citations accumulated by scholarly articles, including the h-index, g-index, e-index, and Google’s i10-index, may be used to evaluate academic productivity in neurological surgery. The present article provides a comprehensive assessment of recent academic publishing output from 103 US neurosurgical residency programs and investigates intradepartmental publishing equality among faculty members.
METHODS
Each institution was considered a single entity, with the 5-year academic yield of every neurosurgical faculty member compiled to compute the following indices: ih(5), cumulative h, ig(5), ie(5), and i10(5) (based on publications and citations from 2009 through 2013). Intradepartmental comparison of productivity among faculty members yielded Gini coefficients for publications and citations. National and regional comparisons, institutional rankings, and intradepartmental publishing equality measures are presented.
RESULTS
The median numbers of departmental faculty, total publications and citations, ih(5), summed h, ig(5), ie(5), i10(5), and Gini coefficients for publications and citations were 13, 82, 716, 12, 144, 23, 16, 17, 0.57, and 0.71, respectively. The top 5 most academically productive neurosurgical programs based on ih(5)-index were University of California, San Francisco, University of California, Los Angeles, University of Pittsburgh, Brigham & Women’s Hospital, and Johns Hopkins University. The Western US region was most academically productive and displayed greater intradepartmental publishing equality (median ih[5]-index = 18, median Ginipub = 0.56). In all regions, large departments with relative intradepartmental publishing equality tend to be the most academically productive. Multivariable logistic regression analysis identified the ih(5)-index as the only independent predictor of intradepartmental publishing equality (Ginipub ≤ 0.5 [OR 1.20, 95% CI 1.20–1.40, p = 0.03]).
CONCLUSIONS
The ih(5)-index is a novel, simple, and intuitive metric capable of accurately comparing the recent scholarly efforts of neurosurgical programs and accurately predicting intradepartmental publication equality. The ih(5)-index is relatively insensitive to factors such as isolated highly productive and/or no longer academically active senior faculty, which tend to distort other bibliometric indices and mask the accurate identification of currently productive academic environments. Institutional ranking by ih(5)-index may provide information of use to faculty and trainee applicants, research funding institutions, program leaders, and other stakeholders.

Abstract
Background Although being a simple and effective index that has been widely used to evaluate academic output of scientists, the h-index suffers from drawbacks. One critical disadvantage is that only h-squared citations can be inferred from the h-index, which completely ignores excess and h-tail citations, leading to unfair and inaccurate evaluations in many cases. Methodology /Principal Findings To solve this problem, I propose the h’-index, in which h-squared, excess and h-tail citations are all considered. Based on the citation data of the 100 most prolific economists, comparing to h-index, the h’-index shows better correlation with indices of total-citation number and citations per publication, which, although relatively reliable and widely used, do not carry the information of the citation distribution. In contrast, the h’-index possesses the ability to discriminate the shapes of citation distributions, thus leading to more accurate evaluation. Conclusions /Significance The h’-index improves the h-index, as well as indices of total-citation number and citations per publication, by possessing the ability to discriminate shapes of citation distribution, thus making the h’-index a better single-number index for evaluating scientific output in a way that is fairer and more reasonable.

Abstract
The h-index has received wide attention in recent years. The area under the citation function is divided by the h-index into three parts, representing h-squared, excess and h-tail citations. The h-index by itself does not carry information for excess and h-tail citations, which can play an even more dominant role than h-index in determining the citation curve, and therefore it is necessary to examine the relations among them. A triangle mapping technique is proposed here to map the three percentages of these citations onto a point within a regular triangle. By viewing the distribution of mapping points, shapes of the citation functions can be studied in a perceivable form. As an example, the distribution of the mapping points for 100 most prolific economists is studied by this technique.

Abstract
We explore opportunities for assessing and advancing Human Resource Development (HRD) research through an integrative literature review of scientometric theories and methods. Known as the “science of science,” scientometrics is concerned with the quantitative study of scholarly communications, disciplinary structure and assessment and measurement of research impact. The integrative review of scientometric literature showed importance in evaluating HRD research and publications, including citation analysis, citing behavior analysis, and Social Science Citation Index (SSCI) journal quality control process. We discuss three major implications for engaging HRD scholars in evaluating and assessing HRD research and scholarly communications for the quality control and self-regulation of HRD research.

PAGEL PS, HUDETZ JA. H-index is a sensitive indicator of academic activity in highly productive anaesthesiologists: results of a bibliometric analysis. Acta Anaesthesiol Scand 2011; 55:1085-9. [PMID: 22092205 DOI: 10.1111/j.1399-6576.2011.02508.x] [Citation(s) in RCA: 80] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 07/06/2011] [Indexed: 11/30/2022]
Abstract
BACKGROUND H-index distinguishes differences in scholarly output across faculty ranks in anaesthesiologists, but whether h-index also identifies differences in other aspects of productivity is unknown. We tested the hypothesis that h-index is an indicator of not only publication record, but also grant funding and mentoring in highly productive US academic anaesthesiologists. METHODS We conducted an internet analysis of the Foundation for Anesthesia Education and Research Academy of Research Mentors in Anesthesiology (n = 43). Publications, citations, citations per publication, and h-index for each investigator were obtained using the Scopus(®) . Total grants, active grants, years of funding, and duration of longest funded grant were recorded using the US National Institutes of Health Research Portfolio Online Reporting Tools(®) . Members were surveyed to identify the number of their career trainees and those who obtained independent funding. RESULTS The median [IRQ (Interquartile range)] h-index of members was 23 [17-32 (8-50)]. Members published 136 [100-225 (39-461)] papers with 3573 [1832-5090 (150-11,601)] citations and 21 [15-32 (4-59)] citations per publication. Members received four [3-7 (0-10)] grants and were funded for 29 [17-45 (0-115)] grant-years. Survey respondents (79%) mentored 40 [26-69 (15-191)] trainees, three [2-6 (0-20)] of which subsequently received funding. Members with h-indices greater than the median had more publications, citations, citations per publication, grants, and years of funding compared with their counterparts. H-index was associated with total citations, active grants, and the number of trainees. CONCLUSIONS In addition to publication record, h-index sensitively indicates grant funding and mentoring in highly productive US academic anaesthesiologists.

Abstract
Citation metrics have rapidly gained importance in today's landscape and are being increasingly utilized as a yardstick in making several important decisions regarding academic funding and appointments. The impact factor has traditionally been the metric most often employed in this regard. However, the emergence of the Hirsch index has provided an alternative to the impact factor. The h-index, despite its flaws, continues to gain acceptance and popularity in the medical community. Several medical journals have evaluated and endorsed the use of the h-index. However, it must be interpreted with all of its limitations in mind.

Perspectives on the formation of an interdisciplinary research team. Biochem Biophys Res Commun 2009; 391:1155-7.

Abstract
As research funding becomes more competitive, it will be imperative for researchers to break the mentality of a single laboratory/single research focus and develop an interdisciplinary research team aimed at addressing real world challenges. Members of this team may be at the same institution, may be found regionally, or may be international. However, all must share the same passion for a topic that is bigger than any individual's research focus. Moreover, special consideration should be given to the professional development issues of junior faculty participating in interdisciplinary research teams. While participation may be "humbling" at times, the sheer volume of research progress that may be achieved through interdisciplinary collaboration, even in light of a short supply of grant dollars, is remarkable.
