“…Collaboration in social, psychological and therapeutic research could be established between developed and developing countries. A bibliometric study on sleep apnea showed that the probability of citation increased by 1.23 times for each additional author, and by 2.23 times for each additional country represented; independent of time since publication, journal, or the country of the author (Huamani et al 2015). …”

Background: Autism spectrum disorders (ASD) are a group conditions classified as neuro-developmental disorders. Research activity on ASD is important for all countries since such disorders have both social and health consequences. The objective of this study was to analyze research output on ASD during the period 2005-2014. Methods:All articles relevant to ASD plus all articles published in autism journals were retrieved using Scopus database. VOSviewer software was used to create density and network visualization maps. Bibliometric indicators were investigated by analyzing annual research output, languages, countries, institutions, journals, title terms, highly cited articles, and co-authorship relations.Results: A progressive annual growth of ASD research was observed from 2005 to 2014. During this period, a total of 18,490 articles were retrieved. The majority of these articles was published in Journal of Autism and Developmental Disorders with 48,416 citations and an average citation of 23.59 citations per article. The countries that published the largest number of articles were the United States (US) (n = 8594; 46.48 %), United Kingdom (n = 2430; 13.14 %) and Canada (n = 1077; 5.8 %). International collaborations produced 30.18 % of the articles published by top 10 productive countries. King's College London (UK) ranked first in number of publications and total citations. The top 10 list of productive institutions was dominated by US academic and research institutions. More than half of the highly cited articles were in the field of molecular genetics. Articles with more than 50 citations were published mainly by authors from USA, UK and Canada. Conclusions:There is a worldwide growth of publications on ASD led by countries in Northern America and Europe. Retrieved articles were published in a wide range of journals. Molecular genetics of ASD is the primary hot topic on ASD. For some leading countries, intra country collaboration is dominant.

“…International collaboration in research is highly needed and should be encouraged since most low and middle income countries cannot fund such research and might not have the advanced technical and medical tools used to investigate poverty-related diseases or health issues. Furthermore, international collaboration increases the quality of publications and chances of articles to be cited and published in high impact journals (Huamani et al 2015). …”

Bibliometric analysis of medicine-related publications on poverty (2005–2015)

et al. 2016

BackgroundPoverty is a global problem. The war against poverty requires not only financial support, but also poverty-related research to pinpoint areas of high need of intervention. In line with international efforts to fight poverty and negative consequences, we carried out this study to give a bibliometric overview of medicine-related literature on poverty. Such a s study is an indicator of the extent of interaction of various international key players on the war against poverty-related health problems.MethodsScopus was used to achieve the objective of this study. The time span set for this study was 2005–2015. Poverty-related articles under the subject area “Medicine” were used to give bibliometric indicators such as annual growth of publications, international collaboration, highly cited articles, active countries, institutions, journals, and authors.ResultsThe total number of retrieved articles was 1583. The Hirsh-index of retrieved articles was 56. A modest and fluctuating increase was seen over the study period. Visualization map of retrieved articles showed that “HIV”, infectious diseases, mental health, India, and Africa were most commonly encountered terms. No significant dominance of any particular author or journal was observed in retrieved articles. The United States of America had the largest share in the number of published articles. The World Health Organization and Centers for Disease Prevention and Control were among top active institutions/organizations. International collaboration was observed in less than one third of publications. Top cited articles focused on three poverty-related health issues, mainly, infectious diseases, malnutrition, and child development/psychology. Most of top articles were published in high impact journals.ConclusionsData indicated that articles on poverty were published in high influential medical journals indicative of the importance of poverty as a global health problem. However, the number publications and the extent of international collaborations was lower than expected given the huge burden of poverty-related health problems.

“…Some of our findings are similar to those reported in other scientific topics, particularly that the United States dominates world scientific production. [8][9][10][11][12][13][14] As in other citation analyses, several shortcomings need to be addressed in the current study. First, the exclusive use of pleural effusion as the search parameter may have resulted in the overlooking of some articles which employed other key terms (eg, empyema, pleurodesis, thoracentesis, etc).…”

Background: Research in pleural diseases has traditionally been neglected but is now growing. Objectives: This study aimed to analyze scientific research trends on pleural effusions over the last decades. Method: We conducted a bibliometric analysis of the Scopus database from its inception to March 2016, searching for original articles and reviews on ''pleural effusion'' (key word). Journal, year of publication, number of citations, authors and their affiliations, and the Hirsch (H)-index for some of these variables were recorded and analyzed. Results: A total of 15 982 documents were retrieved, of which half have been published in the last 18 years and a quarter during the last 8 years. Chest ranked first regarding the number of documents on pleural effusions (both absolute number and yearly rate) and their scientific relevance (H-index of 76). The United States had contributed the most to pleural research productivity (23%). American pulmonologists Dr Richard Light and Dr Steven Sahn exhibited the highest number of papers (206 and 156, respectively) and author H-indexes (44 and 38, respectively). Conclusion: There is growing research activity in the field of pleural effusions, which has gained relevance and visibility in clinical respiratory journals. The United States is the leader in quantity and quality of research productivity in pleural medicine.
