Extracellular vesicles transport variable content and have crucial functions in cell–cell communication. The role of extracellular vesicles in cancer is a current hot topic, and no bibliometric study has ever analyzed research production regarding their role in breast cancer and indicated the trends in the field. In this way, we aimed to investigate the trends in breast cancer management involved with extracellular vesicle research. Articles were retrieved from Scopus, including all the documents published concerning breast cancer and extracellular vesicles. We analyzed authors, journals, citations, affiliations, and keywords, besides other bibliometric analyses, using R Studio version 3.6.2. and VOSviewer version 1.6.0. A total of 1151 articles were retrieved, and as the main result, our analysis revealed trending topics on biomarkers of liquid biopsy, drug delivery, chemotherapy, autophagy, and microRNA. Additionally, research related to extracellular vesicles in breast cancer has been focused on diagnosis, treatment, and mechanisms of action of breast tumor-derived vesicles. Future studies are expected to explore the role of extracellular vesicles on autophagy and microRNA, besides investigating the application of extracellular vesicles from liquid biopsies for biomarkers and drug delivery, enabling the development and validation of therapeutic strategies for specific cancers.

Fiscal transparency is known to influence the quality of public resource management, in terms of a more efficient and effective allocation of these scarce resources. In view of the relevance of this subject, the objective of this work was to produce a bibliometric study, at the global level, of the literature associated with the influence caused by fiscal transparency on the efficiency and effectiveness of public spending on health and also to undertake a brief literature review addressing the main concepts on the subject. The bibliometric analysis was carried out based on data collected from Scielo, Portal de Periodicos Capes (subject search), Scopus and Web of Science databases. Publications from the last 20 years were evaluated, identifying 131 authors and 52 scientific journals. The results show that the effects of fiscal transparency on the efficiency and effectiveness of public spending are the subject of scientific study in various social spheres, such as education, human development and public safety, among others. On the other hand, the health theme is the most addressed among authors and journals with at least two published articles.

Objective: To verify bibliometric indicators of the scientific production available in online journals that approach workplace bullying and nursing. Method: A bibliometric study making use of Bradford’s law, Zipf’s law, and textual statistics was carried out with publications in Portuguese, English, and Spanish, made available in national and international databases, from 2000 to 2016. Results: The sample was made up of 111 publications. The main authors had connections with 91 institutions distributed in 24 countries. The United States, Brazil, and Australia were the countries with the most publications. The populations of the studies were made up of nursing professionals and students, and the hospital environment was the most studied setting. The journals with a higher number of publications have international scientific influence. The terms that presented greater semantic power and high frequency in the abstracts were: bullying; assedio moral; and acoso laboral. Conclusion: Indicators showed that workplace bullying occurs in the nursing work environments of several countries, and the number of publications on this theme has tended to increase. Diversifying methods and study settings is important to contribute to the advancement of knowledge and fight against this violence.
