Bibliometric analysis of schistosomiasis research in Southeast Asia (1908-2020)

History of research on Aedes albopictus (Diptera: Culicidae) in Europe: approaching the world's most invasive mosquito species from a bibliometric perspective

The Asian tiger mosquito, Aedes albopictus (Skuse), is an invasive species native to Southeast Asia. This insect, which is an important vector of arbovirus such as dengue, Zika, and chikungunya, has spread rapidly to several parts of the world over the last few decades. This study employed a bibliometric approach to explore, for the first time, Ae. albopictus research activity and output in Europe. We used the Web of Science Core Collection data source to characterize the current scientific research. A total of 903 publications from 1973 to 2022 were retrieved. We also provided a comprehensive analysis by year of publication; distribution by most productive European countries, institutions, and authors; collaboration networks; research topics; most productive journals; and most cited publications. Results showed a notable increase in the number of studies after the chikungunya virus outbreak in Northeast Italy in 2007. More than 60% of these publications across the entire European continent originated from France and Italy. Research output related to 'population and community ecology' topics was significantly high. The most common type of collaboration was national, which occurred between institutions in the same European country. By providing an overview of Ae. albopictus research in Europe, this work contributes to upcoming debates, decision-making, planning on research and development, and public health strategies on the continent and worldwide.

Trends in Nanoparticles for Leishmania Treatment: A Bibliometric and Network Analysis

Leishmaniasis is a neglected tropical illness with a wide variety of clinical signs ranging from visceral to cutaneous symptoms, resulting in millions of new cases and thousands of fatalities reported annually. This article provides a bibliometric analysis of the main authors' contributions, institutions, and nations in terms of productivity, citations, and bibliographic linkages to the application of nanoparticles (NPs) for the treatment of leishmania. The study is based on a sample of 524 Scopus documents from 1991 to 2022. Utilising the Bibliometrix R-Tool version 4.0 and VOSviewer software, version 1.6.17 the analysis was developed. We identified crucial subjects associated with the application of NPs in the field of antileishmanial development (NPs and drug formulation for leishmaniasis treatment, animal models, and experiments). We selected research topics that were out of date and oversaturated. Simultaneously, we proposed developing subjects based on multiple analyses of the corpus of published scientific literature (title, abstract, and keywords). Finally, the technique used contributed to the development of a broader and more specific "big picture" of nanomedicine research in antileishmanial studies for future projects.

India’s Contribution in Neglected tropical diseases: A Scientometrics Study.. [DOI: 10.32388/wrjp0g] [Citation(s) in RCA: 0] [Impact Index Per Article: 0]

Neglected Tropical Diseases (NTDs) are a group of parasitic and bacterial infections that are prevalent in tropical and subtropical regions. These diseases mainly affect improvised people of developing countries living in abject poverty. These are called "neglected" because they are often overlooked by the mainstream healthcare systems, despite their significant impact on public health. India has a large burden of NTDs and has made significant progress in developing and implementing interventions to control and eliminate these diseases. It is important to note that Indian researchers and institutions contribute to global research efforts in various fields, including neglected tropical diseases (NTDs). In this context, this paper is a scientometric assessment of Indian authors’ contribution in NTDs. For this purpose, scholarly publication data was downloaded form the Scopus® database of Elsevier science. The study observed developed countries particularly the US and UK are predominant in research on NTDs. Among the ‘Global South’ Brazil and India ranked third and fourth respectively. Indian scholarly output contributes about 6 percent of global contribution. For some diseases, Indian researchers contributes significantly. For example, in Leprosy research India is at the top with 18 percent of publication. For some diseases Indian contributions are comparatively less. This is due to the variation in disease conditions and also in local or regional focus in research. Hence a south-south cooperation is required for a detail investigation and preventions of NTDs.

Growth in chikungunya virus-related research in ASEAN and South Asian countries from 1967 to 2022 following disease emergence: a bibliometric and graphical analysis

BACKGROUND

ASEAN (Association of Southeast Asian Nations) is composed of ten Southeast Asian countries bound by socio-cultural ties that promote regional peace and stability. South Asia, located in the southern subregion of Asia, includes nine countries sharing similarities in geographical and ethno-cultural factors. Chikungunya is one of the most significant problems in Southeast and South Asian countries. Much of the current chikungunya epidemic in Southeast Asia is caused by the emergence of a virus strain that originated in Africa and spread to Southeast Asia. Meanwhile, in South Asia, three confirmed lineages are in circulation. Given the positive correlation between research activity and the improvement of the clinical framework of biomedical research, this article aimed to examine the growth of chikungunya virus-related research in ASEAN and South Asian countries.

METHODS

The Scopus database was used for this bibliometric analysis. The retrieved publications were subjected to a number of analyses, including those for the most prolific countries, journals, authors, institutions, and articles. Co-occurrence mapping of terms and keywords was used to determine the current state, emerging topics, and future prospects of chikungunya virus-related research. Bibliometrix and VOSviewer were used to analyze the data and visualize the collaboration network mapping.

RESULTS

The Scopus search engine identified 1280 chikungunya-related documents published by ASEAN and South Asian countries between 1967 and 2022. According to our findings, India was the most productive country in South Asia, and Thailand was the most productive country in Southeast Asia. In the early stages of the study, researchers investigated the vectors and outbreaks of the chikungunya virus. In recent years, the development of antivirus agents has emerged as a prominent topic.

CONCLUSIONS

Our study is the first to present the growth of chikungunya virus-related research in ASEAN and South Asian countries from 1967 to 2022. In this study, the evaluation of the comprehensive profile of research on chikungunya can serve as a guide for future studies. In addition, a bibliometric analysis may serve as a resource for healthcare policymakers.

A retrospective analysis of schistosomiasis related literature from 2011-2020: Focusing on the next decade

BACKGROUND

Schistosomiasis, an ancient and neglected tropical disease, which poses a huge threat to over 200 million people globally. It is necessary to have a general summary of schistosomiasis research after the new roadmap 2021-2030 issued by WHO. This study analyzes the current status of schistosomiasis research from the perspective of the One Health concept by analyzing important research literature published from 2011 to 2020, while further highlighting research priorities, difficulties, and research directions in order to propose suggestions for tropical disease studies research.

METHODS

Published literature related to schistosomiasis was searched from the Web of Science Core Collection (WoSCC) database. Focusing on a visual analysis of the main research literature in the field of schistosomiasis, CiteSpace software was used to conduct co-occurrence analysis with keywords, countries, institutions, and authors. Moreover, clustering and burst analyses of keywords and co-citation analysis of authors, publications, and journals were performed.

RESULTS

A total of 6638 schistosomiasis-related articles were published from 2011 to 2020, all of which can be sourced from the WoSCC database. The publication of schistosomiasis research has remained stable over the past 10 years, and contains studies in the area of human epidemiology, animal surveillance and the environment. The top five high-frequency keywords included Schistosoma mansoni, schistosomiasis, infection, praziquantel, and Schistosoma japonicum. The keywords formed nine clusters, including praziquantel, epidemiology, Schistosoma japonicum, helminths, protein, diagnosis, schistosomiasis, response, and haematobium. In recent years, most research studies focused on the mechanism of liver fibrosis, eliminating schistosomiasis, controlling risk factors, and the relationship between schistosomiasis infection and host immunity. The most productive countries include the United States, China, and Brazil, and the most productive institutions are the University of Basel, the Swiss Tropical and Public Health Institute, and the University of São Paulo. Highly productive authors include Jürg Utzinger and Donald P. McManus. At the time of writing, the author with the highest co-citation frequency (993 times) was Peter Hotez, and the journal with the highest co-citation frequency (3,720 times) was PLoS Neglected Tropical Diseases. Human schistosomiasis, published by Colley et al. (2014), was the most frequently co-cited publication (494 times).

CONCLUSIONS

This study provides a preliminary description of the current status of schistosomiasis research and an initial exploration of future research directions. The One Health concept was applied in the field of schistosomiasis control, as confirmed by this bibliometric analysis. Our study provides guidance for the development of research on schistosomiasis and other neglected tropical diseases.

Advances in research on schistosomiasis and toxoplasmosis in China: A bibliometric analysis of Chinese academic journals published from 1980 to 2021

BACKGROUND

The scale-up of zoonoses prevention control and eradication in China, coupled with numerous academic articles in Chinese journals has led to the development of new tools and strategies aimed at further consolidating parasite control goals. As a result, there is a growing need for an up-to-date understanding of the research progress and prevention and control experience of parasitic diseases in China.

METHODS

To understand the research status of schistosomiasis and toxoplasmosis in China, academic articles published in Chinese journals from 1980 to 2021 were retrieved from China National Knowledge Infrastructure (CNKI) and Wanfang databases. The Bibliographic Items Co-occurrence Matrix Builder (BICOMB) software was used to extract and analyze the keyword frequencies. The 'K/A ratio' as the frequency of a keyword that occurred in all the articles within a certain time stage was calculated to compare the popularity of the same keyword in different time stages. Keyword co-occurrence network maps were constructed by VOSviewer software.

RESULTS

A total of 18,508 articles in the research field of Schistosoma and 13,289 articles in the field of Toxoplasma gondii were included. Results in both fields showed some similarities: the annual number of articles presented an increasing trend before entering the 21^st century and decreased rapidly in recent years. Two opposite changing trends of keyword frequency could be observed in the K/A ratio analysis: the K/A ratios of 'Surveillance' and 'Infection' continuously increased over time, while those of 'Schistosoma mansoni' and 'Mesenteric lymph nodes' decreased. The diversification of keyword co-occurrence networks could be observed in the co-occurrence network maps.

CONCLUSIONS

This bibliometric analysis reveals trends in research themes in the fields of Schistosoma and Toxoplasma gondii from 1980 to 2021, presenting China's experience such as a high degree of government involvement and multidisciplinary participation in schistosomiasis and toxoplasmosis control and elimination.

Landscape, barriers, and facilitators of scientific productivity in schizophrenia research in Southeast Asia: A bibliometric analysis

Background

Schizophrenia research has significantly grown in the past years. However, there is no comprehensive evaluation of schizophrenia research publications from Southeast Asia (SEA). Thus, this study determined the characteristics and trends of published articles about schizophrenia in SEA through a bibliometric analysis.

Methods

A database search on schizophrenia research in SEA countries was performed using the Scopus databases from 1973 to 2021. Bibliometric information was obtained from Scopus, and network visualization was conducted using VOSviewer software.

Results

There were 1068 articles on schizophrenia from SEA from 1973 until 2021. Schizophrenia research outputs from SEA started to increase from 2000 onwards. Singapore, Malaysia, and Thailand were the most productive countries in schizophrenia research and had the most collaborations. Most schizophrenia research in SEA was published in Asia- or SEA-based journals. The research hotspots for schizophrenia in SEA included treatment, pathophysiology, symptomatology, and psychological and social aspects of schizophrenia. Lastly, correlation analysis showed that gross domestic product per capita, research and development (R&D) expenditures, number of researchers in R&D, number of physicians, and international research collaborations were significantly correlated with higher research productivity and scientific impact in schizophrenia research.

Conclusion

In conclusion, this study showed the trends and gaps for research in SEA and the socioeconomic factors correlated with research productivity for schizophrenia in SEA. This study emphasized increasing financial support and collaborations for schizophrenia research to improve research productivity in schizophrenia in the SEA region.

Dyslipidemia research landscape and socioeconomic facilitators of scientific productivity in Southeast Asia

BACKGROUND

The growing prevalence of lipid disorder in Southeast Asia (SEA) resulted in an increase in clinical and epidemiological studies on dyslipidemia in the region. Thus, there is a need to summarize the existing evidence from the literature.

AIMS

This paper determined the research landscape of dyslipidemia in SEA. This study also identified the socioeconomic facilitators of scientific productivity in dyslipidemia research in SEA.

METHODS

A database search of dyslipidemia literature in SEA countries was performed using the Scopus database. Bibliographic information was obtained, and network visualization of collaboration among countries and keywords was created using VOSviewer software.

RESULTS

This bibliometric analysis showed a continuous increase in published articles in SEA, most of which were from universities and hospitals in Thailand, Singapore, Malaysia, and Indonesia. The usual topics of dyslipidemia research in SEA include epidemiology, pathophysiology, comorbidities and complications, and treatment options for dyslipidemia. Research & development expenditure (total citations: p = 0.037; h-index: p = 0.031) and researchers in R&D (total citations: p = 0.005; h-index: p = 0.017) were positively correlated with citations and h-index for dyslipidemia publications from SEA countries. Moreover, the number of research collaborations within SEA and worldwide was positively correlated with the total publications, citations, and h-index of SEA countries for their dyslipidemia research outputs.

CONCLUSION

In summary, this bibliometrics study showed an increasing trend of dyslipidemia research in SEA countries. Policymakers and administrators should invest more in dyslipidemia studies to propose better strategies in curbing the prevalence of this condition in SEA.

Trends in Naegleria fowleri global research: A bibliometric analysis study

Naegleria fowleri is one of the most dangerous protozoan agents. This article describes a bibliometric review of the literature on N. fowleri research indexed in WoS during a 51-year period. The VOSviewer visualization methodology was used to conduct a bibliometric study. The data included articles from the Web of Science database, nations, institutions, journals, keywords, co-authorship, co-citations, international collaborations, and citation rates. A total of 1106 articles were retrieved from the Web of Science database. The articles were cited 21,904 times in total (cited 12,138 times without self-citations). The average citation per article was 19.82. The Hirsch index was 63. The leading country according to the number of published articles was the United States of America (USA) (n = 447; 40.416%), followed by Mexico (n = 80; 7.233%), and Australia (n = 63; 5.696%). Other than these top three countries, the publications were from 74 countries globally. Especially after the 2000s, both the number of citations and the number of publications exhibited an increasing trend. The Virginia Commonwealth University (USA) (9.584%), Centers for Disease Control Prevention (USA) (8.770%), and Instituto Politecnico Nacional Mexico (4.069%) were the leading affiliations. Most of the leading affiliations were from the USA and Mexico. In conclusion, a bibliometric evaluation of N. fowleri was performed for the first time. Authors affiliated with institutions in the USA and Mexico have led scientific production on PAM. Efforts should be made to help developing countries with the highest prevalence of N. fowleri to develop scientific research networks with the USA and/or Mexico in order to increase research with interdisciplinary teams.
