Introduction: This study presents a global research scenario in the broad domain of osteoarthritis (OA) research, using quantitative and qualitative publication and citation indicators. Methods: The study is based on 45,368 global publications, sourced from the Scopus bibliographical database, covering three decades (1994–2023). We studied the performance of the top 12 developed and top 12 developing countries. The key countries, organizations and authors at national and international levels were identified. The broad subject areas and key journals contributing to global OA research were delineated, besides identifying the broad characteristics of highly cited papers in the field. Results: The United States and China were the most productive countries, while the Netherlands and Canada made the largest citation impact. Harvard Medical School and the University of Sydney made the most contribution, while Boston University and Pfizer Inc., USA registered the highest citation impact. Hunter DJ and Guermazi A were the most productive authors, while Lohmander LS, and Hochberg MC registered the highest citation impact. Osteoarthritis and Cartilage (n = 4879) and Annals of the Rheumatic Diseases (n = 786) published the maximum papers, while Arthritis and Rheumatism and Nature Reviews Rheumatology registered the largest citation impact. The highly cited papers with 100 or more citations constituted 6.25% of the total publications. Conclusions: There has been a systematic growth of publications on OA. The research on OA was mainly done in developed countries, with the maximum publications coming from the United States of America, China and Canada. The most impactful publications on OA were from the Netherlands, Canada and the United States of America. [ABSTRACT FROM AUTHOR]

Introduction. The occurrence of osteoporosis (OP) has drawn considerable attention from scholars around the world due to the significant impacts thereof on the social economy and the quality of human life. OP research has been rapidly expanding since the inclusion of microRNAs (miRNAs) as critical regulators of gene-expression. However, despite the ability to evaluate miRNA gene therapy in OP being enhanced, there has been a scarcity of updated citation analyses that reflect such developments. In the present study, through bibliometric analysis, the global research activity and trends in regard to the relationship between OP and miRNAs were reviewed. Methods. Publications related to miRNA and OP from 2000 to 2021 were retrieved via Web of Science (WoS). The data included publication years, countries, journals, institutions, authors and keywords, and were sorted and summarized by bibliometrics, before being visually analyzed through VOS Viewer. Results. In the past five years, 599 articles have been published, with said studies accounting for 79.11% of all relevant documents, indicating the increased interest in the present research topic. The country with the highest contribution rate was China, and the publication rate of Journal of Bone and Mineral Research was the highest, followed by Bone. The institutions with the highest contribution rate were Nanjing Medical University. The most frequently occurring keywords were clustered into five groups. The research area of the first group described that circulating miRNA would be a potential biomarker for postmenopausal osteoporosis (PMOP). The remaining four groups involved the influences of miRNAs and exosomes on the osteogenic and adipogenic differentiation of mesenchymal stem cells (MSCs), and the interactions of lncRNA and miRNA with OP. Conclusions. The results of the present study will expand the research on miRNAs and OP. The research direction with the highest frequency was the miRNAs acting on osteoblasts and osteoclasts. The influence of miRNAs carried by exosomes on the differentiation of MSCs might become an effective method for OP cell-free treatment. [ABSTRACT FROM AUTHOR]

Background: Aflatoxins are fungal metabolites associated with contaminated food products. Intake of aflatoxin-contaminated food results in serious health hazards and even death. Therefore, the aim of this study is to evaluate the global scientific output of research of aflatoxin by using bibliometric techniques. Methods: This bibliometric study was conducted using Scopus database and classified the retrieved publications were classified from different aspects, including the countries/region of focus, journals, authors, institutes, citations, and content analysis to discover any hot and emerging topics. In addition, the bibliometric analysis of the international collaborative network and hot research topics were generated by VOSviewer© software version 1.6.10. The publication period was restricted in the search for two decades (1998–2017). Results: The search engine of the Scopus database found 9845 documents published in the field of aflatoxin. The USA is the top publishing source in the world (22.85%), followed by China (11.85%), India (9.32%), and Italy (5.25%). In earlier years, researchers focused on terms related to the topics of "sources and biosynthesis of aflatoxin", "health effects by aflatoxin", and "detoxification and treatment of aflatoxin". However, in recent years, researchers pay more attention to the topic of detection and quantification of aflatoxin. Conclusions: The quantity of research in global aflatoxin has substantially increased over the past two decades. The evaluation of the historical status and development trend in aflatoxin scientific research can guide future research, and ultimately provide the basis for improving management procedures for governmental decisions, healthcare, industries, and educational institutions.
