Visualizing temporal dynamics and research trends of macrophage-related diabetes studies between 2000 and 2022: a bibliometric analysis

Global research and current trends on nanotherapy in lung cancer research: a bibliometric analysis of 20 years

BACKGROUND

Lung cancer ranks as one of the most rapidly growing malignancies. Which is characterized by its poor prognosis and a low survival rate due to late diagnosis and limited efficacy of conventional treatments. In recent years nanotechnology has emerged as a promising frontier in the management of lung cancer, presenting novel strategies to enhance drug administration, improve therapeutic efficiency, and mitigate side effects. This research comprehensively evaluates the current state and research trends concerning the application of nanomaterials in lung cancer through bibliometric analysis.

MATERIALS AND METHODS

We employed a systematic approach by retrieving studies from the Scopus database that focused on nanomaterials and lung cancer between 2003 and 2023. Subsequently, we carefully selected relevant articles based on predetermined inclusion criteria. The selected publications were then subjected to bibliometric and visual analysis using softwares such as VOSviewer and Biblioshiny.

RESULTS

A total of 3523 studies that meet inclusion criteria were selected for bibliometric analysis. We observed a progressive increase in the number of annual publications from 2003 to 2023, indicating the growing interest in this field. According to our analysis, China is the primary contributor to publication output among the countries. The "Ministry of Education of the People's Republic of China" was the most influential institution. Among the authors, "Dr. Jack A. Roth" and "Dr. Huang Leaf" had the highest number of publications and cited publications, respectively. The "International Journal of Nanomedicine" was found to be the most prolific journal in this field. Additionally, "Biomaterials" emerged as the most cited journal. Through keyword analysis, we identified five main research themes and future research directions; nono-immunotherapy and green synthesis are the hot topics in this research field.

CONCLUSION

Our study summarized the key characteristics of publications in this field and identified the most influential countries, institutions, authors, journals, hot topics, and trends related to the application of nanomaterials in lung cancer. These findings contribute to the existing body of knowledge and serve as a foundation for future research endeavors in this area. More effective efforts are needed in this field to reduce the burden of lung cancer and help achieve the United Nation's Sustainable Development Goals.

A Bibliometric and Knowledge-Map Analysis of Macrophage Polarization in Insulin Resistance From 1999 to 2023

BACKGROUND

Despite numerous studies confirming the association between insulin resistance (IR) and macrophage polarization, there is a lack of bibliometric analysis in this area. Therefore, our objective is to conduct a comprehensive analysis of published literature and identify potential future research trends using bibliometrics.

METHOD

Publications on the topic of macrophage polarization in IR were gathered from the Web of Science Core Collection database (WoSCC) spanning the years 1999-2023. Bibliometric analysis and visualization were conducted using VOSviewers, CiteSpace, the R package "bibliometrix" and Tableau Public.

RESULT

A total of 3435 articles published between 1999 and 2023 were included in the analysis. These articles originated from 75 countries, with the United States and China leading in contributions. The top five research institutions are the University of California, San Diego, Harvard University, the University of Michigan, Shanghai Jiao Tong University, and Huazhong University of Science and Technology. In this research domain, Diabetes is the most frequently published journal, and the Journal of Clinical Investigation is the most co-cited. Among the 19,398 authors contributing to these publications, Lumeng CN. not only authored the most papers but also received the highest number of co-citations. "Insulin resistance" emerges as a primary keyword in the analysis of emerging research hotspots.

CONCLUSION

For the first time, bibliometric methods have been employed to conduct a comprehensive summary of papers relevant to macrophage polarization in IR. This study aims to identify the current research direction and future research hotspots, offering valuable guidance and insights for scholars in the field.

Transcutaneous vagus nerve stimulation: a bibliometric study on current research hotspots and status

Background

Transcutaneous Vagal Nerve Stimulation (tVNS) has been used as a promising noninvasive neuromodulation technique for the treatment of various systems.The aim of this study was to analyze the research hotspots and future directions of tVNS in the 21st century by using bibliometric methods.

Methods

The study object was the literature related to tVNS from the Web of Science database from 2000 to May 2024. In order to measure and analyze the number of literature issuance, institutions, authors, countries, keywords, co-citations, and journals of publication, we used VOSviewer, Citespace, Bibliometrix R-package, and Scimago Graphica software. A narrative review of the current research content of tVNS was conducted to gain a better understanding of the current state of the field.

Results

A total of 569 papers were included in the study. The results show that from 2000 to 2024, the number of publications shows an increasing trend year by year, involving a total of 326 research institutions. The United States, China, and Germany are the major research centers. The study identified 399 keywords, which roughly formed 11 natural clusters, revealing that the current hotspots of related research are mainly reflected in 3 areas: intervention efficacy on nervous system diseases, mechanism of action of tVNS, and stimulation mode of tVNS. The top 10 most cited references focus on research into the mechanism of action of tVNS.

Conclusion

The efficacy and safety of tVNS have been confirmed in previous studies, but a standardized tVNS treatment protocol has not yet been developed, and most clinical studies have small sample sizes and lack multicenter and multidisciplinary collaboration. Currently, tVNS is used in the treatment of neurological diseases, psychiatric diseases, cardiovascular diseases, and some autoimmune diseases. It is expected that future research in this field will continue to focus on the application of tVNS in central nervous system diseases and the exploration of related mechanisms, and at the same time, with the rise of non-invasive neuromodulation technology, the application of tVNS in other diseases also has great potential for development.

Visualization of the relationship between macrophage and wound healing from the perspective of bibliometric analysis

Macrophages play a crucial role in aiding all phases of the wound-healing process and has garnered increasing attention recently. Although a substantial body of related studies has been published, there remains a lack of comprehensive bibliometric analysis. In this study, we collected 4296 papers from the Web of Science Core Collection database. Three tools including CiteSpace, VOSviewer and one online analytical platform were employed to conduct bibliometric analysis and data visualization. Our results revealed that the annual number of publications related to macrophage and wound healing has increased exponentially with the year. The United States and China stand as the primary driving forces within this field, collectively constituting 58.2% of the total publication output. The application of biomaterials was one of the most concerned research areas in this field. According to references analysis, the current research focus has shifted to diabetic wound healing and regulating macrophage polarization. Based on the keywords analysis, we identified the following research frontiers in the future: exosomes and other extracellular vesicles; bio-derived materials and drug delivery methods such as nanoparticles, scaffolds and hydrogels; immunomodulation and macrophage polarization in the M2-state; chronic wounds, particularly those associated with diabetes; antimicrobial peptides; and antioxidant. Additionally, TNF, IL-6, IL-10, TGF-β1 and VEGF ranked as the five genes that have garnered the most research attention in the intersection of macrophage and wound healing. All in all, our findings offered researchers a holistic view of the ongoing progress in the field of macrophages and wound healing, serving as a valuable reference for scholars and policymakers in this domain.
