Objective To explore the global research status and trends of continuous renal replacement therapy (CRRT) based on knowledge visualization analysis. Methods Based on the Web of Science Core Collection, studies reporting CRRT research that were published between June 2014 and June 2023 were retrieved and collected after manual review. VOSviewer and CiteSpace softwares were used for bibliometric visualization analysis, including publication trends, geographical distribution characteristics, journal distribution characteristics, author contributions, citations, funding source characteristics, and keyword clustering. Results A total of 2708 papers were analyzed, with an increasing trend in the number of articles and citation frequency from 2015 to 2021. The United States was the most prolific country and France was the most influential country. The University of Pittsburgh in the United States had the highest number of publications among research institutions and showed higher motivation for inter-institutional collaboration. The University of Queensland in the Australia had the highest average citation frequency. Professor Rinaldo Bellomo of Australia was the most productive author and Professor Jeffrey Lipman was the most influential. Jason A. Roberts, Jeffrey Lipman and Claudio Ronco were the three authors who had the highest number of collaborations with other authors. Keyword cluster analysis showed that the prognosis of CRRT for renal disease was the focus of research, with hotspots of research being antibiotics, citrate accumulation, plasma replacement, lactate clearance, acute respiratory distress syndrome, and coronavirus disease 2019. Coupling analysis of the literature showed that exploring the indications for CRRT and optimizing treatment prescription were at the forefront of research. Conclusions The present study of CRRT has generally shown an upward trend in the last decade. The management and efficacy of CRRT remains a hot topic of research. Exploring the indications for CRRT and optimizing treatment prescriptions may be a popular research direction and trend in the future.

ObjectiveTo investigate the current status of research in gene therapy for retinitis pigmentosa (RP) from 2005 to 2024. MethodsThe literature related to gene therapy for RP included in the Web of Science Core Collection dataset from January 1, 2005 to September 15, 2024 was retrieved and screened. The bibliometrix package of R software was used to analyze the annual trend of the number of publications, citation frequency, distribution of countries/regions of the literature, and distribution of journals containing the articles. CiteSpace software was used to perform keyword clustering analysis and the keywords bursts analysis. ResultsA total of 209 articles were included. There was an overall fluctuating upward trend of annual publications from 2005 to 2024, with the highest number of publications in 2023 at 26 (12.4%, 26/209), and the lowest number of publications in 2006 at 2 (0.9%, 2/209). There was an overall increasing trend in the frequency of citations to relevant literature. Corresponding authors from the United States had the highest total number of publications with 98 (46.9%, 98/209). Among authors, Hauswirth from the University of Florida, USA, had the most with 25 (12.0%, 25/209). Among institutions, Columbia University, USA, had the most with 55 (26.3%, 55/209). Among journals, Mol Ther had the most with 25 (12.0%, 25/209), and it had the highest 2023 impact factor of 12.1. Keyword clustering analysis yielded eight valid clusters, namely #0 P23H, #1 AAV, #2 PDE6B, #3 CRB1, #4 RPGR, #5 antisense oligonucleotide, #6 NR2E3, and #7 NRL, which intersected with each other with good continuity. The keywords bursts analysis showed that the keyword with the longest emergence time was RNAi, followed by PDE and PDE6. USH2A, CRB1, CRISPR Cas9, base editing, and ORF15 were keywords that emerged in recent years and were continuously studied. ConclusionsRP gene therapy research literature has shown an increasing trend from 2005 to 2024, with the highest number of publications from research organizations and scholars in the United States. Currently, studies focus on RHO, PDE6B, CRB1, RPGR, NR2E3, and NRL gene. In recent years, there has been a gradual increase in studies on USH2A, CRB1 genes, and the RPGR ORF15 region. CRISPR Cas9 and base editing gene therapy strategies are being developed.
Objective To analyze and reveal the domestic and abroad studies on polypoidal choroidal vasculopathy (PCV) by bibliometric. Methods Foreign articles were searched from American Institute of Scientific Information online database of web of science (WOS) database, Chinese articles were searched from China National Knowledge Infrastructure (CNKI) database. The age distribution, national and regional, funding agency and citation of the PCV literatures published before December 31 2012 were analyzed by software Bibexcel and SPSS 17.0. Results Totally 696 literatures were analyzed, including 440 foreign literatures and 256 Chinese literatures. The numbers of foreign literatures were gradually increased since 2000, significantly after 2007, reached the maximum at 2011.

ObjectiveTo analyze the global status, hotspots, and trends in atrial fibrillation anticoagulation research.MethodsWe searched Web of Science Core Collection to collect relevant literature on atrial fibrillation anticoagulation from 2006 to 2020. The visualization software CiteSpace and VOSviewer were used to analyze co-citation, co-occurrence, and emergence analysis on publishing organizations, journals, and keywords and to explore the research hotspots and frontiers.ResultsA total of 11764 related studies were retrieved. In recent years, research on anticoagulation of atrial fibrillation has become increasingly popular. Most of the published researches were from North America, and the primary institution was the University of Birmingham. Research hotspots mainly focused on warfarin, stroke prevention, new oral anticoagulants, antithrombotic and anticoagulants, and complicating diseases. The research frontiers were the new oral anticoagulants, and the antithrombotic management of atrial fibrillation with coronary heart disease.ConclusionsThe global hotspot in atrial fibrillation anticoagulant research is warfarin, stroke prevention, new oral anticoagulants, antithrombotic and antiplatelet therapy, and complicated diseases. The research focuses on the study of novel oral anticoagulants and the antithrombotic management of atrial fibrillation complicated with coronary heart disease.
Objective To learn the hotspots of study in ischemic optic neuropathy (ION). Methods Literature on ION published in January 2000 to July 2012 was identified in Pubmed database. MeSH terms that frequently appeared were identified and co-word analysis was carried out by cluster analysis. Then a network was drawn using social network analysis. Results A total of 1045 papers were included. The United States, England, Germany, France and Netherlands together accounted for 71.53% (748) of the articles. There were 28 high-frequency MeSH terms and hot topics clustered into four fields. The appearance frequency of MeSH showed that most research focused on: (1)postoperative or arteritic ION; (2)epidemiology, pathology and diagnosis of ION; (3)pathophysiology and therapy of ION; (4) chemically induced ION. Conclusion The international main research focus of ION includes four fields, which may provide reference or scholars both in scientific research and clinical research.
ObjectiveTo investigate the hotspots from researches on imaging of pancreatic neuroendocrine tumor in recent five years. MethodsThe bibliographies from research literatures on imaging of pancreatic neuroendocrine tumor from 2010 to 2015 in PubMed database were downloaded. The Bicomb 2.0 bibliographies analysis software was used to count high-frequency of Mesh major topics (MJMEs). SPSS 22.0 statistical software was applied for clustering analysis with MJMEs, then to get the topic hotspots. ResultsA total of 357 literatures were screened out during the years of 2010-2015. The MJMEs which frequency > 13 were 28. Taken the 28 MJMEs into clustering analysis, then three research hotspots were clustered. ConclusionResearches on imaging of the pancreatic neuroendocrine tumor in recent five years are mainly in terms of imaging techniques, a comparative study of pathology and endoscopic ultrasonography-fine needle aspiration, imaging and disease treatment.
This is the third paper in the evidence-based medicine glossary series. We count terms and phrases having the words"evidence-based" in the title using bibliometrics. We then analyze the frequency of emergence, publication period, languages, and journal of the glossaries published. Finally, we focus on the link between the title and the glossary, and explore the development of trends in EBM.
