Mapping the landscape and structure of global research on binge eating disorder:Visualization and bibliometric analysis

BACKGROUND Binge-eating disorder(BED)is a clinical syndrome and is considered the most common type of eating disorder.However,our understanding of the global performance and progress of BED research is limited.AIM To describe and perform a bibliometric analysis of the state of BED research.METHODS The term‘Binge eating’was searched in the title throughout the previous year’s up to December 31,2020.We searched the Scopus and Reference Citation Analysis for publications on Binge eating.The VOSviewer software version 1.6.17 was used to produce the network visualization map of the most frequent author,collaborative relationships between countries/regions,and to determine the hotspots related to binge eating research.In addition,conventional bibliometric indicators were generated.RESULTS The search strategy found 2713 total articles and an average of 62 articles per year.Among them,‘Article’represented 82.49%of the publications(n=2238 articles)and was the most frequent type,followed by reviews(n=243;8.96%).The number of publications increased steadily during the last decade of the study period.One hundred and thirty-two countries contributed to binge eating research,with 1495(55.11%)articles published in the United States,followed by Italy with 256(9.44%),the United Kingdom with 183(6.75%),and Germany with 182(6.71%).Currently,the main hot topics related to BED are‘type of treatment and management and treatment provided to BED”;“processes and pathways to binge eating”;and‘diagnosis,signs and symptoms,comorbidities and prevalence and associated factors with BED’.CONCLUSION The number of publications has increased noticeably during the previous decade.There are indeed relatively few publications on BED from low-and middle-income nations,so much is to be learned from the experience of all countries.Studies on this topic are critical in all countries to discover risk factors and effective intervention measures.Although our findings are preliminary,they imply that the future prospects for interventions aimed at BED management are bright,focusing on complex models of care and long-term maintenance of therapeutic gains.

Mapping the global research landscape on insulin resistance: Visualization and bibliometric analysis

BACKGROUND Insulin resistance is a risk factor for metabolic syndromes and is associated with a wide variety of metabolic illnesses,including obesity,type 2 diabetes,and cardiovascular disease.AIM To investigate and map global insulin resistance studies.METHODS A bibliometric methodology was applied to the literature retrieved from the Scopus database and Reference Citation Analysis(https://www.referencecitationanalysis.com)by using a validated search strategy.The study period was limited from 2002 to 2021.Bibliometric indicators and mapping were presented.RESULTS A total of 26808 articles on the topic of insulin resistance were included in the Scopus database.The articles included research articles(n=21918;81.76%),review articles(n=2641;9.85%),and letters(n=653;2.44%).During the study period,136 countries contributed to the research on insulin resistance.The highest number of articles was from the United States(n=7360;27.45%),followed by China(n=3713;13.85%),Japan(n=1730,6.45%),Italy(n=1545;5.54%),and the United Kingdom(n=1484;5.54%).The retrieved articles identified two main research themes:“inflammatory mechanisms in the regulation of insulin resistance”and“mechanisms linking obesity to insulin resistance”.CONCLUSION Our data show that insulin resistance has steadily gained interest from researchers,as evidenced by the number of citations and yearly publications.Publications have grown significantly in the last decade,while low-income countries with greater burdens continue to produce fewer publications in this field.This approach might assist researchers in choosing new research areas and recognizing research hotspots and frontiers.In the future,perhaps high-quality clinical evidence will be acquired.

Global research production in neonatal abstinence syndrome: A bibliometric analysis

BACKGROUND Recently,neonatal abstinence syndrome(NAS)emerged as a significant global concern with a dramatic increase in healthcare expenditures.The incidence of the NAS has increased notably in the past decade and emergence as a global public health problem.AIM To evaluate the development and trend of global NAS research from 1958 to 2019 by bibliometric analysis.METHODS Analyzed aspects included publication output per year,language,document types,journals,countries/territories,h-index,authors,and top research priorities.The VOSviewer was used to determine the top research priorities,and trends,and to present bibliometric networks concerning various dimensions,such as coauthorship,authors,and countries.RESULTS A total of 1738 articles were retrieved in the Scopus database from 1958 to 2019.It was found that the great majority of the total NAS documents(n=1295)were original articles followed by reviews(n=268)and letters(n=48).The most productive countries in the NAS field were the United States(n=833),Canada(n=112),the United Kingdom(n=111),and Germany(n=77).Treatment and hospital outcomes in NAS,evidence-based nurse-driven interventions for the care of newborns with NAS,and a systematic reviews and network meta-analysis for therapeutic approaches of NAS were found in recent years(after 2010),compared with terms such as pathophysiology,mechanisms of NAS,and signs and symptoms in the early years.CONCLUSION Treatment and pediatric outcomes and the effectiveness of pharmacological treatment may be frontiers in the NAS field,and continued efforts from researchers are needed in those topics.
