Mapping the global research landscape on nutrition and the gut microbiota:Visualization and bibliometric analysis

BACKGROUND Nutrition is a significant modifiable element that influences the composition of the gastrointestinal microbiota,implying the possibility of therapeutic diet methods that manipulate the composition and diversity of the microbial.AIM To overview research papers on nutrition and gut microbiota and determines the hotspots in this field at the global level.METHODS Scopus and Reference Citation Analysis were used to construct a bibliometric technique.It was decided to create bibliometric indicators and mapping as in most previous studies.2012 through 2021 served as the study's timeframe.RESULTS A total of 5378 documents from the Scopus database were selected for analysis.Of all retrieved studies,78.52%were research papers(n=4223),followed by reviews(n=820;15.25%).China ranked first with a total number of articles of 1634(30.38%),followed by the United States in second place with a total number of articles of 1307(24.3%).In the last decade,emerging hotspots for gut microbiota and nutrition research included"gut microbiota metabolism and interaction with dietary components","connection between the gut microbiota and weight gain",and"the influence of high-fat diet and gut microbiota on metabolic disorders".CONCLUSION This is the first thorough bibliometric analysis of nutrition and gut microbiota publications conducted on a global level.Investigation of the association between nutrition/diet and the gut microbiota is still in its infancy and will be expanded in the future.However,according to recent trends,the"effect of gut microbiota and high-fat diet on metabolic disorders"will be an increasing concern in the future.

Current global research landscape on COVID-19 and cancer: Bibliometric and visualization analysis

BACKGROUND Cancer is a severe public health issue that seriously jeopardizes global health.In individuals with coronavirus disease 2019(COVID-19),cancer is considered an independent risk factor for severe illness and increased mortality.AIM To identify research hotspots and prospects,we used bibliometrics to examine the global production of COVID-19 literature published in the field of oncology.METHODS Data on publication output were identified based on the Scopus database between January 1,2020,and June 21,2022.This study used VOSviewer to analyze collaboration networks among countries and assess the terms most often used in the titles and abstracts of retrieved publications to determine research hotspots linked to cancer and COVID-19.The Impact Index Per Article for the top 10 high-cited papers collected from Reference Citation Analysis(RCA)are presented.RESULTS A total of 7015 publications were retrieved from the database.The United States published the greatest number of articles(2025;28.87%),followed by Italy(964;13.74%),the United Kingdom(839;11.96%),and China(538;7.67%).The University of Texas MD Anderson Cancer Center(n=205,2.92%)ranked first,followed by the Memorial Sloan-Kettering Cancer Center(n=176,2.51%).The European Journal of Cancer(n=106,1.51%)ranked first,followed by the Frontiers in Oncology(n=104,1.48%),Cancers(n=102,1.45%),and Pediatric Blood and Cancer(n=95;1.35%).The hot topics were stratified into“cancer care management during the COVID-19 pandemic”;and“COVID-19 vaccines in cancer patients”.CONCLUSION This is the first bibliometric analysis to determine the present state and upcoming hot themes related to cancer and COVID-19 and vice versa using VOSviewer during the early stages of the pandemic.The emergence of hot themes related to cancer and COVID-19 may aid researchers in identifying new research areas in this field.

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.
