Background:Urinary tract infection(UTI)is a prevalent bacterial infection affecting adults and pediatric populations,with distinct patterns observed in infants.This bibliometric analysis aims to provide a comprehensive overview of the research landscape in pediatric UTI from 1990 to 2022,exploring qualitative and quantitative research output,contributing authors,institutions,countries,collaborative links,and hotspot topics.Purpose:This study aims to evaluate the qualitative and quantitative research output and trends in UTI in the pediatric population through a bibliometric analysis.The analysis covers highly cited articles,contributing authors,institutes,countries,collaborative links,and future research prospects.Methods:A bibliometric analysis was conducted using the Web of Science platform with a search string focused on pediatric UTI articles published between January 1990 and December 2022.The analysis employed the Bibliometrix R-package software and VOSviewer for collaborative networks and keyword co-occurrence maps.Results:Out of 1399 published articles,81.7%were research articles.The annual growth rate of publications was 4.46%.The USA led in contributions,with the University of Pennsylvania being the most productive institution.The"Journal of Pediatric Urology"and"Pediatric"were prominent journals.Lorenzo AJ from the University of Toronto was the top author.Collaborative networks highlighted the significance of collaboration in pediatric UTI research.Conclusion:In conclusion,this bibliometric analysis provides a detailed snapshot of the research landscape in pediatric urinary tract infections.With 1399 articles analyzed,the study reveals a sustained interest and growth rate of 4.46%,emphasizing ongoing efforts to address pediatric UTI challenges.The USA dominates contributions,reflecting its pivotal role in advancing knowledge.The top institutions,journals,and authors are identified,with collaborative networks highlighted.Keyword co-occurrence networks unveil critical themes,notably"vesicoureteric reflux,""management,"and"diagnosis." 展开更多

The Gravity Recovery and Climate Experiment(GRACE)is the most important gravity satellite to date in human history.Since its launch in 2002,GRACE time-varying gravity has had an unprecedented impact on earth science and has generated revolutionary changes.Because of natural phenomena such as climate warming,glacial melting,sea level rise,and earthquakes,earth science research has become an increasingly popular discipline in recent years.This article summarizes the importance of GRACE time-varying gravity,its application to geoscience,and its development.We analyzed the historical development and current status of GRACE time-varying gravity as well as research hotspots by searching the literature in the core collection databases of the China National Knowledge Infrastructure and the Web of Science over the past 20 years.The CiteSpace and VOSviewer software packages were applied with reference to the principle of literature metrology.Our investigation and analysis of characteristic indexes,such as the numbers of publications,co-occurrence of keywords,and co-citation of documents,uncovered the wide application and promotion of gravity satellites,especially GRACE time-varying gravity,in earth science.The results showed that the number of publications addressing GRACE data and time-varying gravity theory is increasing annually and that the USA,China,and Germany are the main producers.The Chinese Academy of Sciences,the National Aeronautics and Space Administration of the United States,and the Helmholtz Association of German Research Centres rank among the top three institutions in the world in terms of producing the most publications on this topic.We found that GRACE time-varying gravity plays unique roles in measuring changes in terrestrial water storage changes,ice and snow melting and sea level changes,and(co)seismic gravity changes,as well as in promoting other disciplines. 展开更多

The nanocellulose is a material that has gained much attention in the recent years.So,the relevance of Brazil in this field was evaluated concerning the scientific publications in Web of Science.Next,the Brazilian groups were mapped using a bibliometric procedure on these data.Then,more factors were analyzed from them too.They were the sources to extract the nanocellulose in Brazil,the methods to do it,the characterizations to determine its dimensions and the funding agencies of these researches.The results identified 69 Brazilian groups.Besides,the bacterial cellulose was the most common source.While the acid hydrolysis was the most used method.By its turn,the size characterization was mostly by scanning electron microscopy.At last,the most important agencies were the CNPq,the CAPES and the FAPESP.Giving these points,it was possible to suggest the opportunities to develop the nanocellulose research in Brazil. 展开更多

The present study aims to analyze the state of the art of scientific studies about the Overtopping device used to convert sea wave energy into electrical energy,by means the Bibliometric methodology.The development of this study took place through the selection of articles from conference proceedings,as well as national and international journals.The Bibliometric methodology consists of a statistical tool that allows quantifying the measurement of production indexes.Using selected keywords,it was conducted a survey of studies in the online databases of Science Direct,SciELO and Google Scholar.The works found then went through a filtering process,in order to limit the Bibliometric study only to studies about Overtopping devices as sea Wave Energy Converter(WEC).Finally,the investigation of these selected articles was carried out under the optics of production and authorship study,content study and study of bibliographic references.Where it was identified growth in publications related to the topic,methodologies used and,among other indicators,the authors most cited in the analyzed articles.The predominant keywords used were“Wave Energy Converter”and“Overtopping”.It was noted that Brazilian universities are leaders in the productivity,presenting more than 36%of the scientific production regarding Overtopping WECs. 展开更多

Aims:Research on second-generation antipsychotic drugs (SGAs) has experienced great development in last decades.We did a bibliometric study on the scientific publications on SGAs in Japan.Methods: With theEMBASEandMEDLINEdatabases, we chose papers published from Japan with SGA descriptors. Price’s law and Bradford’s law has been used as bibliometric indicators for quantitating production and dispersion, respectively, of published papers on SGAs. We also calculated the participation index of different countries, and correlated those bibliometric data with some social and health data from Japan (such as totalper capitaexpenditure on health and gross domestic expenditure on research and development). Results: A sum of 669 original documents were published from Japan from 1982 to 2011. Those results fulfilled Price’s law, with scientific production on SGAs showing exponential growth (correlation coefficientr= 0.9261, as against anr= 0.8709 after linear adjustment). The most studied SGAs in Japan wererisperidone (n= 192), aripiprazole (n= 109), and olanzapine (n= 106). Division of documents into Bradford zones yielded a nucleus occupied exclusively by theProgress in Neuro-Psychopharmacology and Biological Psychiatry(49 articles). Those publications were in 157 different journals. Seven of the first 10 frequently used journals had an impact factor of being greater than 3. Conclusions: The SGA publications in Japan have been through exponential growth over the studied period, without evidence of reaching a saturation point. 展开更多

Background:To apply CiteSpace software to the hotspot,trend and cutting-edge dynamics of limb spasm after stroke in nearly 20 years.Methods:From 2000 to 2018,spasming literature in the Web of Science database were searched,and cooperative analysis of authors'national institutions was conducted by using CiteSpace software,keyword analysis and cluster analysis,citation analysis of authors'literature journals,and visual map.Results:2005 articles were retrieved,and the number of articles increased year by year,and the country with the most articles was the United States.Keyword analysis shows that mechanistic research and clinical treatment of spasticity are research hotspots in this field.The most posts are Northwestern Univ and Univ Verona.Conclusion:Through the CiteSpace software analysis of spasticity literature,it is found that the research focus is embodied in the nerve regeneration technology and the standardized clinical study of botulinum toxin type A application,which has certain reference significance for the future research direction of spasticity. 展开更多
