Objective: To evaluate, qualitatively, the Brazilian nursing journals and identify their strengths and weaknesses when compared to international journals in the area. Methods: A historic approach regarding the period from 2012 to 2016. We included national nursing journals indexed in the SciELO Database and international journals with an impact factor above 1.0 and below 1.8 indexed in the WoS and Scopus databases. Results: The national journals met SciELO requirements for internationalization and obtained visibility when they were included in international indexing bases. Their citations were mostly national, with the following mean values: 86% in Portuguese; 12% in Spanish and 2% in English. Conclusion: The excellence requirements of the national journals are being accomplished. The publication of articles in Spanish can impact on the increase of bibliometric indicators.

A high number of citations can indicate the potential of any specific paper to influence other research and generate changes in clinical practice. Analyzing the most-cited papers in a certain scientific field may assist researchers to identify the influential papers as well their main characteristics. The present study aimed to analyze the 100 most-cited papers concerning dental fluorosis (DF) through a bibliometric review. A search was performed in the Web of Science Core Collection database (WoS-CC) in November 2021. The papers were displayed in descending order according to the number of citations in WoS-CC. Two independent researchers performed the selection. Scopus and Google Scholar were used to compare the number of citations with WoS-CC. The following data were extracted from the papers: title, authors, number and density of citations, institution, country, continent, year of publication, journal title, keywords, study design, and theme. Collaborative networks were generated using the VOSviewer software. The top 100 most-cited papers were published between 1974 and 2014 and were cited 6,717 times (ranging from 35 to 417). Community Dentistry and Oral Epidemiology (24%), Journal of Dental Research (21%), Journal of Public Health Dentistry (17%), and Caries Research (13%) published the most papers. Observational studies (60%) and literature reviews (19%) were the most common study designs. The main topics were epidemiology (44%) and fluoride intake (32%). The countries with the highest number of papers were the United States of America (USA) (44%), Canada (10%), and Brazil (9%). The University of Iowa (USA) had the most papers (12%). Levy SM was the author with the highest number of papers (12%). The 100 most-cited papers on DF were mainly observational studies focused on epidemiology and originated in North America. There were few interventional studies and systematic reviews among the most-cited papers concerning this topic.

Nanotechnology has emerged as a promising tool in the clinic to combat several difficult-to-manage diseases, such as cancer, which is the second leading cause of death world-wide. Chemotherapeutic drugs present several limitations such as undesired side effects, low specificity, resistance, and high relapse rates. Triple negative breast cancer (TNBC) is caused by cells that lack specific receptors in their membrane, such as estrogen (ER+) and progesterone (PR+) receptors, or by cells that do not express the amplification of human epidermal growth factor receptor-2 (HER-2+). This cancer type has poor prognosis, high relapse rates, and no targeted therapies. Thus, this study aimed to investigate the trends of nanotechnology research in TNBC and compare the contribution of research from different regions, institutions, and authors. A search of the studies published between 2012 and 2017, related to nanotechnology and TNBC, with different keyword combinations, was performed in the Scopus database. The keywords found in this search were grouped into four clusters, in which “breast cancer” was the most mentioned (1,133 times) and the word “MCF-7 cell line” is one of the latest hotspots that appeared in the year 2016. A total of 1,932 articles, which were cited 26,450 times, were identified. The USA accounted for 28.36% of the articles and 27.61% of the citations; however, none of its centers appeared in the list of 10 most productive ones in terms of publications. The journals Biomaterials and International Journal of Nanomedicine had the highest number of publications. The USA and China had the highest number of articles produced and cited; however, the highest average citation per article was from Singapore. The studies focused on the research of antineoplastic agents in animal models and cell culture, and these were the most used topics in research with nanotechnology and TNBC.

The prevalence of Diabetes Mellitus and, particularly, type 2 diabetes (T2D) is increasing every year worldwide. Therefore, changed glucose homeostasis is associated with altered gut microbiota and with the development of type 2 diabetes mellitus (T2DM) and related complications. Among other concerns, an important aspect within this issue is the reversion of dysbiosis reported to be present in T2D patients, in which diet plays a key role, and particularly dietary fiber has shown a promising position. beta-glucans are heterogeneous non-starch polysaccharides, constituted by D-glucose monomers linked through different beta-glycosidic bonds, and changes in their structure or molecular weight affect the expressed biological properties. They appear in certain cereals, yeasts, or mushrooms and are widely known by their hypocholesterolemia effect. This study explored the current knowledge on the potential of beta-glucans to modulate glucose homeostasis due to their prebiotic action, by performing a bibliometric analysis using the VOSviewer software and a narrative review. The bibliometric analysis showed that, despite the high number of references dealing with beta-glucan and diabetes, there are few articles on glucans, diabetes, and intestinal dysbiosis. The detailed study on preclinical studies and clinical trials conducted during the last decade showed an improvement in glucose homeostasis due to beta-glucan supplementation, studies on biochemical markers, and gut microbiota, and beta-glucan are scarce. Nevertheless, existing data showed, both in animals and humans, a tendency towards an increase in beneficial bacteria and in the production of short-chain fat acids (SCFAs), particularly butyric acid. These aspects should be confirmed in the years to come to establish clear recommendations for.. -glucan as a prebiotic coadjutant in the management of Diabetes Mellitus.
