Global toxocariasis research trends from 1932 to 2015: a bibliometric analysis

Abstract

BackgroundToxocariasis is a highly prevalent parasitic disease in the tropical regions of the world, with its impact on public health being typically underestimated. To better recognise the trends and characteristics of toxocariasis research, this study is a bibliometric analysis of the global toxocariasis research.MethodsSearches were completed on April 5, 2016, using the Scopus database. A search without any language restriction was performed to extract publications dealing with toxocariasis. Terms related to toxocariasis were used to perform a title keyword search.ResultsA total of 2765 publications comprising 11 document types and published between 1932 and 2015 were included in the analysis. Articles were the most popular document form, accounting for 83.62% of all publications, followed by letters (3.80%) and reviews (3.4%). The annual number of research publications increased from 30 in 1980 to 111 in 2015, indicating that the number of publications on toxocariasis has increased slowly over the past 35 years. The United States of America and Japan are the predominant countries of origin, with 303 articles and 207 articles, respectively, followed by Brazil and the United Kingdom, with 180 (6.5%) each. The h-index for all the publications was 60. The highest h-index were for publications from the United Kingdom (h-index value = 43) and the United States (h-index value = 39); these two countries were also involved with the highest number of international collaborations, with 27 and 28 countries, respectively.ConclusionsDeveloped countries, including the United States, Japan, the United Kingdom, France, Germany and Italy, are the world’s leaders in toxocariasis research, contributing to more than 34% of the total published literature. In addition, developing countries, such as Brazil, Poland, Argentina and India, showed a noticeable increase in published papers on toxocariasis research in recent years. A push for more collaboration is needed to achieve a superior research strategy related to toxocariasis at the global level from the viewpoint of epidemiological data, clinical aspects, medical ecology, molecular aspects and treatment practices associated with toxocariasis.

Arab world’s growing contribution to global leishmaniasis research (1998–2017): a bibliometric study

“…No similar study has been found in a detailed literature search to address such those results but other related bibliometric studies have tried to make explanations for such findings [20][21][22]35]. A possible explanation for these findings may be referring to leishmaniasis prevalence rates which are higher in Tunisia and Sudan.…”

“…All leishmaniasis research publications published between January 1998 and December 2017 indexed on the Scopus database were analysed while the ones published in 2018 were excluded because Scopus as a secondary source has not yet archived all the publications from the primary sources for this year. The Scopus was used because it is the most widely accepted and frequently used database for analysis of scientific publications in different fields [22,[31][32][33][34]. The search was completed in November 2018.…”

“…To encourage and strengthen research capacity in the field of neglected tropical diseases, including leishmaniasis, the WHO highlights the periodic review and development of present and national research agendas [18]. A number of global bibliometric studies exist in various infectious diseases [19][20][21][22], including tropical medicine [23][24][25][26]. In addition, several studies have evaluated the research output for leishmaniasis [25,[27][28][29][30].…”

Global research trends in microbiome-gut-brain axis during 2009–2018: a bibliometric and visualized study

“…11th Neufeld et al [66] "Reduced anxiety-like behavior and central neurochemical change in germ-free mice" [95], toxicology [28], social media in psychology [96], parasitic diseases [51,97], and viral diseases [98][99][100]. Additionally, it also reveals that researchers paid great attention on the MGBA mostly in recent years, and published several outstanding articles on top-ranking journals in the medical field such as Science [56] and Nature [64].…”

India's Contribution and Research Impact Leishmaniasis Research: A Bibliometric Analysis

“…[11] But after 2011 onwards specific research were conducted related to leishmaniasis in general; [12][13] or for specific countries and region such as Iran, [14][15] Latin America, [16] South America. [17] The bibliometric study focusing India were reported in parasitic and neglected tropical disease; [18] lymphatic filariasis; [19] and other neglected tropical diseases such as Ascariasis/Toxocariasis, [20] and Schistosomiasis. [21] However, these literature does not reveal any study covering the research impact of India in the field of leishmaniasis.…”
