“…To date, this is the first bibliometric study to assess the output of peer-reviewed publications on toxocariasis at the global level. Previous bibliometric studies have stated the limitations characteristic of using such an approach [23,24,26,27,[62][63][64]. First, the publications might not have been included in the analysis if toxocariasis or its related words were not mentioned in their titles, although these terms might have been found in the text.…”

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.

“…Publications as errata or publications which their scope was not related to MERS-CoV, and publications from 2016 were excluded from the study. Research indicators for the assessment of MERS-CoV research output were determined according to the methods used previously in similar bibliometric studies [32][33][34][35][36][37]. Analysis parameters include date (year) of publication, publication type, patterns of international collaboration, research institutions, journals, impact factor (IF), h-index, language, and times cited.…”

BackgroundMiddle East respiratory syndrome coronavirus (MERS-CoV) is a virus that causes severe viral pneumonia in humans, known to have a high mortality rate and a similarity in clinical symptoms with severe acute respiratory syndrome coronavirus. It was first isolated in Kingdom of Saudi Arabia (KSA) in 2012 and after that, MERS-CoV exhibited outbreaks in several regions of the world. This study aimed to assess the characteristics of publications involving MERS-CoV at global level by using a bibliometric analysis.MethodsScopus database was searched on March 4, 2016 for MERS-CoV publications published between 2012 and 2015. It was performed on the same day in order to avoid the possible bias came from update on the database because the metrics are changing over time. All publication types were considered; however publications as errata were excluded. Analysis parameters include year of publication, publication type, patterns of international collaboration, research institutions, journals, impact factor, h-index, language, and times cited.ResultsA total of 883 MERS-CoV research publications were published across the world. The MERS-CoV-associated publications were originated from 92 countries/territories, indicating the international spread of MERS-CoV research. The USA was the largest contributor, with 319 articles published over 4 years, followed by KSA (113 articles). The total number of citations for these publications has already achieved 8,015, with an average of 9.01 citations per each publication. The h-index for MERS-CoV-associated publications was 48. The USA also have the highest h-index (32), followed by KSA (26) and UK (22). Netherland produced the greatest proportion of publications with international research collaboration (72.7 %) followed by the UK (71 %) and Germany (69.1 %) out of the total number of publications for each country.ConclusionsThere is a rapid increase in research activities related to MERS-CoV from 2012 to 2015. This study demonstrates that the MERS-CoV related literature has grown to be more extensive and global over the past 4 years. The bulk of publications in the field of MERS-CoV research are published by high-income countries such as the USA. Furthermore, the USA, the UK and KSA may have higher quality of articles according to the value of h-index.

“…The methodology applied in this study was comparable to recent bibliometric studies [17,[31][32][33][34][35]. This study was focused on identifying WNV publication trends with regard to publication year, publication type, prolific countries, language of publication, as well as, prolific journals, citations, and collaboration patterns.…”

BackgroundWest Nile virus (WNV) is an emerging infectious disease which is most commonly transmitted to humans through mosquito, and is considered a major public-health problem worldwide. The aim of the current study is to bibliometrically analyze the quantity and quality of publications indexed in Scopus from different countries to reveal the characteristics of global research output regarding WNV.MethodsThis study is a bibliometric analysis based on the Scopus database. This study focused on identifying WNV publication trends with regard to publication year, publication type, prolific countries, language of publication, as well as, prolific journals, citations, and collaboration patterns.ResultsA total of 4729 publications were considered in this study, which were published between 1943 and 2016. The annual quantity of literature published before 2000 followed a low rate of research growth; while the quantity of publications after 2000 were published in a stage of rapid development. The country with the greatest number of publications in WNV research field was the USA with 2304 (48.7%) publications, followed by France with 224 (4.7%) publications, and Canada with 222 (4.7%) publications. Contributions from low- and middle-income countries (LMIC) were considerably small, that is, (n = 519 publications; 11%). All publications related to WNV achieved h-index of 140 and were cited 124,222 times. The median [interquartile range] number of citations per article thus amounts to 9 [2-28]. The USA had the highest h-index of 131. Emerging Infectious Diseases is the most productive journal with 227 articles, followed by Journal of Virology with 162 publications. The result designated that Centers for Disease Control and Prevention was ranked the first in terms of publication output, followed by National Center for Emerging and Zoonotic Infectious Diseases.ConclusionsThere is an obvious trend of WNV research after 2000, and countries with high income have more contributions in WNV research field. The research output is low among LMIC. The USA produced the largest number of publications. The Centers for Disease Control and Prevention obtained the leading position of the institutions in terms of publication output. In general, this study not only presents a full view of global WNV research, but also can contribute for future further research in this field.
