Emerging Trends and Research on Hydroxychloroquine Treatment in Diseases From 1991 to 2020
Summary
This bibliometric review analyzed 30 years of published research on hydroxychloroquine, a drug that gained attention during the COVID-19 pandemic. This pharmacological review is not directly related to microplastic research.
Abstract Background Recently, hydroxychloroquine (HCQ) has become a controversial point for whether it functioned in the treatment of coronavirus disease 2019 (COVID-19). The aim of this paper is mainly to explore the international frontiers and trends of HCQ clinical treatment in recent 30 years by bibliometric analysis. Besides, the research prospects and hotspots of HCQ therapy in COVID-19 have further been investigated quantitatively and qualitatively. Methods Publications related to HCQ treatment research from 1991 to 2020 and HCQ studies on COVID-19 from the end of 2019 till now were both obtained from Web of Science Core Collection (WOSCC). Bibliometric analyses were primarily performed via Citespace 5.7.R1 to identify the trends of cooperation between countries and institutions, the research hotspots and frontiers. Results A total of 2642 articles and reviews on HCQ treatment in diseases were included, indicating an increase in number of publications since 2013. The United States was the largest scientific output country, followed by France and China. Trending keywords analysis indicated the hotspot research of HCQ treatment referred to “rheumatoid arthriti,” “chloroquine”, “systemic lupus erythematosus” and “COVID-19”. Moreover, 568 publications on the study of HCQ in COVID-19 therapy were also gathered from WOSCC, which showed the USA ranked first again in the world for its most publications. Further, Aix Marseille University, Univ Tehran Med Sci, Univ Paris, Harvard Med Sch and Huazhong Univ Sci & Technol were the five leading institutions in research of HCQ treatment in COVID-19.Conclusion Visualization knowledge map analysis regarding HCQ clinical treatment over the past 30 years suggested scientists are mainly focused on the autoimmune diseases therapy by HCQ. HCQ research have significantly increased since the end of 2019. Obviously, studies on HCQ in COVID-19 may lead the future direction of this field in recent years. The present study provides valuable information on HCQ research through bibliometric analysis so that researchers may identify new perspective and fields.

Micro(nano)plastics as a vector of pharmaceuticals in aquatic ecosystem: Historical review and future trends
This systematic review examines how microplastics and nanoplastics in water can absorb and carry pharmaceutical drugs, creating a combined pollution threat. When medications attach to tiny plastic particles in rivers and oceans, they may become more harmful to aquatic life and potentially to humans who consume contaminated seafood or water. The research traces how this emerging double-threat has grown since 2018 and identifies key knowledge gaps.
Pharmaceutical and Microplastic Pollution before and during the COVID-19 Pandemic in Surface Water, Wastewater, and Groundwater
This review found that pharmaceutical residues and microplastics are widespread contaminants in surface water, groundwater, and wastewater globally, and that the COVID-19 pandemic amplified both types of pollution, with polypropylene and polyethylene being the most commonly detected plastic polymers.
Global research hotspots and trends on microplastics: a bibliometric analysis
A bibliometric analysis of microplastics publications from 1990 to 2022 found a 19-fold increase in publications and 35-fold increase in citations since 2015, with research clustering around distribution, toxicity, analytical methods, and adsorption of co-pollutants.
Trends, challenges, and research pathways in emerging contaminants: a comprehensive bibliometric analysis
This large-scale bibliometric analysis reviewed over 62,000 studies on emerging contaminants published between 2000 and 2024, finding that microplastics are among the fastest-growing areas of environmental health research. The analysis highlights that understanding how microplastics interact with other pollutants like pharmaceuticals and endocrine disruptors is a critical frontier for protecting human health.
Environmental Fate, Ecotoxicity, and Remediation of Heterocyclic Pharmaceuticals as Emerging Contaminants: A Review of Long-Term Risks and Impacts
This review examines heterocyclic pharmaceutical compounds, which make up over 90% of new medications, as emerging environmental contaminants. These drugs persist in the environment and can cause neurotoxicity, genetic damage, and cancer risk. While not directly about microplastics, the study highlights how persistent chemical pollutants, similar to microplastics, accumulate in the environment and pose long-term health threats.
