Biliary atresia: a scientometric analysis of the global research architecture and scientific developments

Abstract Background Esophageal atresia (EA) and tracheoesophageal fistula (TEF) represent a spectrum of relatively rare and complex malformations, which remain a major therapeutic challenge for most involved specialists. Whereas the number of EA/TEF-related publications is constantly growing, no thorough assessment of the global research architecture has been performed yet. Hence, this study aimed to critically evaluate the scientific EA/TEF activities in relation to geographical developments and existing research networks using a combination of scientometric methodologies and visualization tools. Methods A comprehensive search strategy for the Web of Science™ database was designed to retrieve bibliographic data on scientific EA/TEF publications for the time span between January 1900 and December 2018. The total reseach output of countries, institutions, individual authors, and collaborative networks was analzyed. Semiqualitative research measures, including citation rate and h-index, were assessed. Choropleth mapping and network diagrams were employed to visualize results. Results A total of 4586 publications on EA/TEF were identified, originating from 86 countries (79.0% written in English). The largest number was published by the USA (n = 799; 17.4%), the UK (n = 260; 5.7%), and Canada (n = 190; 4.1%). The USA produced the highest number of co-operative articles (n = 73) and the most productive collaborative networks were established between USA/Canada (n = 22), USA/Netherlands (n = 19), and USA/Germany (n = 13). Scientific papers from the UK received the highest average citation rate, with 17.6 citations per item, whereas the USA, with 47, had the highest country-specific h-index. Eighty-two articles were published under the auspices of multicenter research consortiums and national study groups. The most productive institutions and authors were based in the UK, the USA, France, Canada, Australia, the Netherlands, Finland, and Spain. Conclusions This is the first in-depth analysis of the worldwide EA/TEF research activity, offering unique insights into the global scientific landscape in this field. Over the past decades, EA/TEF research has increasingly become multidisciplinary but the main research endeavors continue to be concentrated in a few high-income countries. International EA/TEF collaborations and translational research should be strengthened to foster true scientific progress with this rare condition.

ObjectiveAbout 2% of all pregnancies are complicated by the implantation of the zygote outside the uterine cavity and termed ectopic pregnancy. Whereas a multitude of guidelines exists and related research is constantly growing, no thorough assessment of the global research architecture has been performed yet. Hence, we aim to assess the associated scientific activities in relation to geographical and chronological developments, existing research networks and socioeconomic parameters.DesignRetrospective, descriptive study.SettingOn the basis of the NewQIS platform, scientometric methods were combined with novel visualising techniques such as density-equalising mapping to assess the scientific output on ectopic pregnancy. Using the Web of Science, we identified all related entries from 1900 to 2012.Results8040 publications were analysed. The USA and the UK were dominating the field in regard to overall research activity (2612 and 723 publications), overall citation numbers and country-specific H-Indices (US: 80, UK: 42). Comparison to economic power of the most productive countries demonstrated that Israel invested more resources in ectopic pregnancy-related research than other nations (853.41 ectopic pregnancy-specific publications per 1000 billlion US$ gross domestic product (GDP)), followed by the UK (269.97). Relation to the GDP per capita index revealed 49.3 ectopic pregnancy-specific publications per US$1000 GDP per capita for the USA in contrast to 17.31 for the UK. Semiqualitative indices such as country-specific citation rates ranked Switzerland first (24.7 citations per ectopic pregnancy-specific publication), followed by the Scandinavian countries Finland and Sweden. Low-income countries did not exhibit significant research activities.ConclusionsThis is the first in-depth analysis of global ectopic pregnancy research since 1900. It offers unique insights into the global scientific landscape. Besides the USA and the UK, Scandinavian countries and Switzerland can also be regarded as leading nations with regard to their relative socioeconomic input.

Greenhouse gases such as sulfur dioxide, nitrogen dioxide, and carbon dioxide have been recognized as the prime cause of global climate change, which has received significant global attention. Among these gases, carbon dioxide is considered as the prominent gas which motivated researchers to explore carbon reduction and mitigation strategies. Research work on this domain expands from carbon emission reporting to identifying and implementing carbon mitigation and reduction strategies. A comprehensive study to map global research on carbon emissions is, however, not available. Therefore, based on a scientometric analysis method, this study reviewed the global literature on carbon emissions. A total of 2945 bibliographic records, from 1981 to 2019, were extracted from the Web of Science core collection database and analyzed using techniques such as co-author and co-citation analysis. Findings revealed an increasing trend of publications in the carbon emission research domain, which has been more visible in the past few years, especially during 2016–2018. The most significant contribution to the domain was reported from China, the United States, and England. While most prolific authors and institutions of the domain were from China, authors and institutions from the United States reported the best connection links. It was revealed that evaluating greenhouse gas emissions and estimating the carbon footprint was popular among the researchers. Moreover, climate change and environmental effects of carbon emissions were also significant points of concern in carbon emission research. The key findings of this study will be beneficial for the policymakers, academics, and institutions to determine the future research directions as well as to identify with whom they can consult to assist in developing carbon emission control policies and future carbon reduction targets.
