A semantically enabled formalism for the knowledge management of Parkinson's disease

Visualized analysis of research on helicopter emergency medical service

BACKGROUND

Numerous studies have confirmed that helicopter emergency medical services (HEMS) play a positive role in prehospital care. However, few studies have used rigorous bibliometric tools to analyze the knowledge structure and distribution of HEMS research.

OBJECTIVES

The purpose of this study was to use bibliometric methods to conduct a quantitative and qualitative analysis of the HEMS-related literature and to determine the research status and hotspots of HEMS research.

METHODS

CiteSpace was used for bibliometric analysis of the HEMS-related literature retrieved from the Web of Science database from 1989 to 2021.

RESULTS

A total of 1378 HEMS-related literature were included. Collaboration among countries, authors, and institutions needs to be strengthened. The topics in HEMS research have mainly focused on the effectiveness of helicopter emergency medical services for trauma patients and the comparison of transport effectiveness between helicopters and ground emergency medical services on trauma patient transport. Research over the past 10 years has mainly focused on the application of HEMS in patients with trauma, myocardial infarction, cerebral apoplexy, application of tracheal intubation technology in HEMS, and advanced airway management. In recent years, HEMS research trends have mainly included out-of-hospital cardiac arrest, and transport.

CONCLUSIONS

CiteSpace was used to visualize and analyze the HEMS-related literature, which visually reflected the research status and hot spots, providing references for the topic selection and development direction of HEMS research.

A Bibliometric Analysis of Research Trends of Acupuncture Therapy in the Treatment of Migraine from 2000 to 2020

BACKGROUND

Migraine is the second-leading cause of disability worldwide. It is often characterized by attacks of severe, mostly unilateral, pulsating headache associated with symptoms such as photophobia, phonophobia, nausea, vomiting, and cutaneous allodynia. Acupuncture therapy has been used worldwide for the treatment of migraine. However, no visual bibliometric analysis has been conducted on the effects of acupuncture on migraine over the past 20 years. Therefore, this study aimed to explore the current status and trends on the use of acupuncture in the treatment of migraine from 2000 to 2020.

PURPOSE

The objective of this study is to identify the current status and emerging trends of the global use of acupuncture on migraine from 2000 to 2020 using CiteSpace and VOSviewer.

METHODS

Web of Science databases were searched for publications related to acupuncture therapy for treating migraine between 2000 and 2020. CiteSpace and VOSviewer were used to analyze the number of publications per year, countries, institutions, authors, journals, references, and keywords.

RESULTS

A total of 572 publications were included in the final analysis. The total number of publications has continued to increase with some fluctuations over the past 20 years. The most productive country and institution in this field were the USA, and Chengdu University of Traditional Chinese Medicine, respectively. The most active and cited authors were Liang FR and Linde K, respectively. Cephalalgia was the most productive, cited, and co-cited journal. The Linde K (2005) had the highest co-citation, citation number and centrality. The keywords "migraine" ranked first in frequency. The common type of migraine (tension-type headache), research method (randomized controlled trial, multicenter, double-blind), acupuncture's role (prophylactic, quality of life, pain), and evaluation (meta-analysis, systematic review) were the hotspots and frontier trends of acupuncture therapy on migraine between 2000 and 2020.

CONCLUSION

The present study examined the research-related trend in acupuncture therapy on migraine using bibliometric methods and identified the statement and research frontiers over the past two decades. This may help researchers to identify potential hotspots and new directions for future research in this field.
