Conducted on randomized clinical trials (RCTs) addressing antibiotic resistance in the PubMed database, this bibliometric analysis explores relevant sources, keyword co-occurrence, institutional co-authorship, global collaboration patterns, and evolving research trends. Utilizing an electronic search on January 13, 2024, employing the term "antibiotic resistance," 252,657 results were retrieved, of which 2,962 RCTs were analyzed. The dissemination of RCTs exhibited a variable distribution from 1965 to 2023, with a peak in 2014, noteworthy peaks in 1993-1994 and 2002-2003, contrasting declines in 1990-1991 and 2007-2008, and a consistent decrease post 2018. The University of California emerged as a predominant institution, and the journal "Antimicrobial Agents and Chemotherapy" substantially contributed. The annual growth rate stood at 1.2%, with 97 single-authored documents, an average of 8.76 co-authors per document, and 8.89% international co-authorships. Co-occurrence analysis highlighted prevalent themes, including double-blind clinical trials and significant keywords like human immunodeficiency virus (HIV) infections, Helicobacter infections, metronidazole, and amoxicillin. Trend analysis revealed a chronological shift from penicillin to HIV and Helicobacter drug therapies, culminating in combination antibacterial therapy for multiple bacterial strains. The prevailing trend in antibiotic resistance publications involved single-country endeavors, with the United States leading in collaboration frequency. The findings indicate a need to foster international collaboration, promote interdisciplinary research, support emerging trends, encourage open-access publication, and address declines in research activity, particularly RCTs.
This study provides a comprehensive overview of the current landscape in drug-resistant tuberculosis research. An extensive electronic search was conducted on PubMed and Scopus databases to identify clinical trials related to drug-resistant tuberculosis. Network analysis and visualization were performed on the data using the Biblioshiny App and VOSviewer software.

This study analyzes the most relevant authors, sources, cooccurrence of keywords, thematic map, and trend topics of the most recent and most cited research papers on semaglutide, a glucagon-like peptide-1 receptor agonist (GLP-1 RA). Also, the content of the 25 most cited papers is summarized. A total of 2995 results appeared in an online electronic search performed on 14 August 2023 in the Scopus database using the term semaglutide. The most recently published 500 articles and most cited 200 documents were selected for bibliometric analysis. Network analysis visualization was conducted with the help of the VOSviewer software (version 1.6.18) (Centre for Science and Technology Studies, Leiden, the Netherlands) and Biblioshiny (it is a shiny application providing a web interface for bibliometrix) (Department of Economics and Statistics, University of Naples Federico II, Naples, Italy). After excluding duplicates and editorials, the data analysis found that 495 most recent documents were published in 279 journals by 2461 authors, and 200 most cited papers were published in 103 sources by 1241 authors. There is an increasing trend in the number of research papers from 2014 to 2022, with a peak in 2022. The most relevant authors in the most recent semaglutide research papers are Chen and Zhang. The pertinent authors of the most cited research papers on semaglutide are Lingvay and Khunti. The most common keywords used in the most recent and most cited research papers are semaglutide, obesity, diabetes mellitus type 2, glucagon-like peptide-1, glucagon-like peptide-1 receptor agonist, antidiabetic agent, liraglutide, and cardiovascular disease (CVD). The most relevant source is "Diabetes, Obesity and Metabolism" for the research papers on semaglutide. Trend topic analysis suggests that most of the research between 2020 and 2022 on semaglutide was done on non-insulin-dependent diabetes mellitus. The most cited papers provide essential insights into using semaglutide in managing type 2 diabetes mellitus (T2DM), obesity, and related conditions, along with their potential benefits, side effects, and possible mechanisms of action. This analysis highlights that the pharmacological effects of semaglutide extend beyond its role as a glycemic regulator.
