Global research on sinonasal inverted papilloma over the past two decades: a bibliometric analysis

Objective

This study aimed to investigate the global research status, hot topics, and prospects in the field of sinonasal inverted papilloma (SNIP) through bibliometric analysis.

Methods

The literature on SNIP was retrieved and downloaded from the Web of Science Core Collection from 2002 to 2021. The bibliometric and visualisation networks of SNIP were constructed using VOSviewer 1.6.18, CiteSpace 6.1. R2, and a bibliometric online analysis platform.

Results

A total of 560 original articles about SNIP research were included, involving 2,457 authors from 610 institutions in 45 countries. The number of SNIP publications showed an overall rising trend, with an average annual output of 28 articles and almost 3 times as many articles published in 2020 as in 2002. The analysis of keyword burst detection indicated that EGFR mutation, malignant transformation and infection are emerging research hotspots. Moreover, EGFR mutation, KRAS mutation, malignant tumour, metallothionein 2a gene, pre-operative diagnosis, HPV-negative tumour, and expression were among the 11 key clusters of co-cited references.

Conclusions

This study provided a comprehensive, systematic, and objective analysis and visualised knowledge map of SNIP over the past 2 decades. In particular, current hotspots and prospective trends in the field of SNIP have been identified. These results highlight the future direction of SNIP research for rhinologists.

National Trends in Allergic Rhinitis and Chronic Rhinosinusitis and COVID-19 Pandemic-Related Factors in South Korea, from 1998 to 2021

INTRODUCTION

Existing studies provide insights into the prevalence and environmental factors associated with allergic rhinitis (AR) and chronic rhinosinusitis (CRS) globally. However, limitations still persist in these studies, particularly regarding cohort sizes and the duration of follow-up periods, indicating a need for more comprehensive and long-term research in these fields. Our study aimed to investigate the prevalence, long-term trends, and underlying factors of these conditions in the general population of adult participants (≥19 years) in Korea.

METHOD

We analyzed data from adult participants (≥19 years) from the Korea National Health and Nutrition Examination Survey (KNHANES) study to determine the prevalence of AR and CRS from 1998 to 2021. To analyze prevalence trends before and during the COVID-19 pandemic, we employed a weighted linear regression model and obtained β-coefficients with 95% confidence intervals (CI).

RESULTS

Between 1998 and 2021, over a span of 24 years, the comprehensive KNHANES study included 146,264 adult participants (mean age: 47.80 years, standard deviation: 16.49 years; 66,177, 49.3% men). The prevalence of AR and CRS increased from 1998 to 2021, with AR prevalence rising from 5.84% (95% CI, 5.57-6.10) in 1998-2005 to 8.99% (8.09-9.91) in 2021 and CRS from 1.84% (1.70-1.97) in 1998-2005 to 3.70% (3.18-4.23) in 2021. However, the increasing trend has slowed down during the COVID-19 pandemic era.

CONCLUSIONS

The significance of continuous monitoring and focused interventions for AR and CRS is underscored by this study. The observed deceleration in the rising prevalence of AR and CRS during the pandemic indicates the possibility of beneficial impacts from lifestyle modifications triggered by the pandemic. These findings call for additional research to explore potential protective effects in greater depth.

Practical recommendations for managing severe chronic rhinosinusitis with nasal polyps in the era of biologics

Objective

We conducted a national survey to understand how rhinology practice has changed with the advent of biologics and how this affected patients with uncontrolled, severe chronic rhinosinusitis with nasal polyps (CRSwNP). We aimed to analyse the results of the survey and infer practical recommendations for clinical practice.

Methods

A group of ear, nose, and throat specialists (ENTs) experienced in the management of CRSwNP developed a 74-question survey. ENTs from rhinology centres authorised to prescribe biologics in the context of the national health system were invited to answer it between 01/05/2022 and 31/07/2022. The responses underwent descriptive analyses, and the authors discussed the results and derived practical recommendations for clinical practice.

Results

ENTs working in rhinology centres changed their practices coinciding with the advent of biologics. CRSwNP evaluations have become more complex because they involve diagnostic confirmation, determining the patients' immunologic profile, and other factors. We observed heterogenous behaviours in practice that may be conditioned by the novelty of the topic. The results of the survey were used to develop practical recommendations for ENTs and are summarised herein.

Conclusions

Clinical practice in rhinology outpatient clinics has changed profoundly in the era of biologics. Our practical recommendations for clinicians working in rhinology centres are expected to help standardise practice and improve care.

The evolution of minimal residual disease: key insights based on a bibliometric visualization analysis from 2002 to 2022

Background

The topic of minimal residual disease (MRD) has emerged as a crucial subject matter in the domain of oncology in recent years. The detection and monitoring of MRD have become essential for the diagnosis, treatment, and prognosis of various types of malignancy.

Aims

The purpose of this study is to explore the research trends, hotspots, and frontiers of MRD in the last two decades through bibliometric analysis.

Methods

We employed Web of Science databases to carry out a bibliometric visualization analysis of research on 8,913 academic papers about MRD research from 2002 to 2022. VOSviewer, CiteSpace, RStudio, and a bibliometric online analysis platform were mainly used to conduct co-occurrence analysis and cooperative relationship analysis of countries/regions, institutions, journals, and authors in the literature. Furthermore, co-occurrence, co-citation, and burst analyses of keyword and reference were also conducted to generate relevant knowledge maps.

Results

In the past 20 years, the number of MRD research papers has presented an overall rising trend, going through three stages: a plateau, development, and an explosion. The output of articles in the United States was notably superior and plays a dominant role in this field, and the Netherlands had the highest average citation per article. The most productive and influential institution was the University of Texas MD Anderson Cancer Center. Blood published the most papers and was the most cited journal. A collection of leading academics has come to the fore in the research field, the most prolific of which is Kantarjian HM. It was found that the application of MRD in "acute myeloid leukemia", "acute lymphoblastic leukemia", "multiple myeloma", as well as the detection technology of MRD, are the research hotspots and frontiers in this domain. Furthermore, we analyzed the co-citation network of references and found that the top 10 co-cited references were all associated with MRD in hematological malignancies.

Conclusion

This bibliometric visualization analysis conducted a thorough exploration into the research hotspots and trends in MRD from 2002 to 2022. Our findings can aid researchers in recognizing possible collaborations, guiding future research directions, and fostering the growth of MRD detection and monitoring technologies.

Bibliometric analysis of Ewing sarcoma from 1993 to 2022

BACKGROUND

Ewing sarcoma has attracted more attention in recent years but has yet to be bibliometrically analyzed. Hence, this study investigated the trend of Ewing sarcoma over the past 30 years with bibliometric analysis.

METHODS

Original publications related to Ewing sarcoma were obtained from the Science Citation Index Extension (SCI-E), Social Sciences Citation Index (SSCI), and Web of Science Core Collection (WoSCC) between 1993 and 2022. CiteSpace and VOSviewer were used to extract the countries/regions, institutions, authors, journals, references, and keywords involved in this topic to identify and analyze the research hotspots and trends in this field.

RESULTS

Over the past 30 years (especially in the past five years), the number of articles published on Ewing sarcoma continued to increase, and the most published country was the United States of America (USA). High-frequency keywords included "Ewing sarcoma", "tumor", "family", "bone", "chemotherapy", "expression", "primitive neuroectodermal tumor", "prognostic factors", "children", and "survival rate". According to the analysis of keyword saliency of Ewing sarcoma, we found that "chromosome translocation", "intergroup", "sarcoma", "genomic landscape", and "children oncology group" were emerging research hotspots. The timeline of the cluster map of co-cited literature indicated that the treatment of Ewing sarcoma emerged as a research hotspot.

CONCLUSION

Researchers' understanding of Ewing sarcoma has improved dramatically over the past 30 years. At present, the research hotspots of Ewing sarcoma mainly focus on the aspects of "chromosome translocation", "intergroup", and "sarcoma". In addition, the timeline of the cluster map of co-cited literature indicated the emergence of the treatment of Ewing sarcoma as a research hotspot.

A bibliometric and visualization analysis of global research on vestibular schwannoma

BACKGROUND

Vestibular schwannoma is the most common benign tumor in the pontocerebellar horn region. As the tumor grows, it often causes severe hearing loss due to compression of nearby nerves, resulting in a lower quality of life. This study examined vestibular schwannoma-related research through a bibliometric and visualization analysis, and it explored current trends and research hot spots.

METHODS

Research related to vestibular schwannoma published from 2002 to 2021 was searched using the Web of Science Core Collection. The processing and visualization analysis of the data were conducted using R software, VOSviewer, and CiteSpace.

RESULTS

A total of 3,909 publications were included in this study, and an overall increasing trend in the annual output of publications was found. The United States, Germany, and the United Kingdom were the most prolific countries, publishing the most articles. Germany had the most frequent international cooperation and the highest centrality score. The Mayo Clinic, University of California, and Harvard University were the three most productive institutions. Otology & Neurotology was the most prolific journal, and MJ Link was the most productive and highest scoring author for centrality. Current frontier topics mainly focused on "hearing preservation" and "radiosurgery". A map of trends in topics and a thematic graph revealed that "hearing loss", "vertigo", "magnetic resonance imaging", "radiosurgery", "stereotactic radiosurgery", and "gamma knife" were the topics of focus of current discussions.

CONCLUSION

Hearing preservation is a current frontier topic in this area. Radiosurgery has a promising future in the field of vestibular schwannoma, and stereotactic radiosurgery is a focus of global attention. Bibliometric and visualization analysis offer a unique and objective perspective of the field of vestibular schwannoma and may assist scholars in the identification of new research directions.
