BACKGROUND Despite the current global trend of reduction in the morbidity and mortality of neglected diseases, dengue’s incidence has increased and occurrence areas have expanded. Dengue also persists as a scientific and technological challenge since there is no effective treatment, vaccine, vector control or public health intervention. Combining bibliometrics and social network analysis methods can support the mapping of dengue research and development (R&D) activities worldwide. OBJECTIVES The aim of this paper is to map the scientific scenario related to dengue research worldwide. METHODS We use scientific publication data from Web of Science Core Collection – articles indexed in Science Citation Index Expanded (SCI-EXPANDED) – and combine bibliometrics and social network analysis techniques to identify the most relevant journals, scientific references, research areas, countries and research organisations in the dengue scientific landscape. FINDINGS Our results show a significant increase of dengue publications over time; tropical medicine and virology as the most frequent research areas and biochemistry and molecular biology as the most central area in the network; USA and Brazil as the most productive countries; and Mahidol University and Fundacao Oswaldo Cruz as the main research organisations and the Centres for Disease Control and Prevention as the most central organisation in the collaboration network. MAIN CONCLUSIONS Our findings can be used to strengthen a global knowledge platform guiding policy, planning and funding decisions as well as to providing directions to researchers and institutions. So that, by offering to the scientific community, policy makers and public health practitioners a mapping of the dengue scientific landscape, this paper has aimed to contribute to upcoming debates, decision-making and planning on dengue R& D and public health strategies worldwide.

Objective: The study’s purpose has been to analyze some bibliometric indicators of nursing Dissertations and Theses with regards to the Calgary Family Assessment Model (CFAM) produced in Brazil. Methods: It is a bibliometric study, where the sample consisted of fourteen Dissertations and seven Theses, which were published over the period from 2002 to 2014, and selected by consulting the Capes Portal, BDENF, BDTD and CEPEn. Results: The indicators have shown a reduced quantity of publications on the subject during the period scrutinized. Most of the studies were from Nursing Postgraduate Programs in the Southeast region. Most of the surveyed studies were written in dissertation fashion. There was a predominance of studies with a qualitative approach. Conclusion: Despite the reduced number of Dissertations and Theses of Nursing who have used the CFAM in Brazil, studies based on this model attracted the interest of researchers in spreading the knowledge produced by prestigious scientific journals in the research field.

Synergies between globalization and knowledge economy were suggested to direct biomedical research towards economically-interested activities. In this context, research in malaria, a disease endemic to poverty, may be at a paradoxical stance. This study addresses this issue assessing whether malaria research is driven by the accumulation of economic and/or other forms of capital. Drawing upon academic and epistemic capitalism, malaria research is characterized through the analysis of all Web of science-indexed publications involving Portuguese organizations (1900-2014; n=467). First, data was systematized by content and bibliometric analyses. Subsequently, multiple correspondence analysis revealed a bi-dimensional landscape (who’s publishing; what’s published) and cluster analysis identified three profiles (beginners; local appropriations; global science). This study reveals the construction of Portugal’s scientific system and unveils the assimilation of dominant modes of organizing, doing and thinking despite malaria’s research low profit potential. Extending this approach to other biomedical fields can unravel the dimensions underlying science’s (re)construction.

INTRODUCTION The steadily increasing prevalence of diabetes globally has captured researchers’ attention. Cuban production of scientific articles on diabetes has not been studied from a bibliometric perspective. OBJECTIVE Characterize the production and impact of research and review articles on diabetes by Cuban authors in journals listed in the Scopus bibliographic database, as well as related collaboration among Cuban institutions and between Cuban and non-Cuban institutions. METHODS A bibliometric analysis was conducted using 2000-2017 data from the Scopus database. The following search strategy was used: descriptor (diabetes), country (Cuba), publication source (journal), article type (original research, review article). Bibliographic indicators of production, visibility, impact and collaboration were examined. RESULTS Cuba contributed 3.2% of Latin American production and 0.1% of global production related to diabetes. Within Cuba’s scientific production (610 articles, 538 original research and 72 review), 85.9% had a Cuban corresponding author (Cuban leadership). In articles with international collaboration (22.9%), however, most (67.9%) had non-Cuban corresponding authors. A total of 47% (287) were articles involving a single institution. Only 11.1% were published in top-ranked journals, and 14.4% were cited >10 times. Cubans were lead authors on 0.3% of the most frequently cited (top 10%) articles on diabetes in Scopus. A total of 38.4% of this production appeared in low-impact journals and 57.9% in Cuban journals. Articles published in English accounted for 30% of total and obtained higher impact in terms of citations than articles in Spanish. The strongest networks for scientific collaboration were those that connected Cuban and US researchers. CONCLUSIONS Cuban scientists conduct research on diabetes, but their work is not highly visible in the peer-reviewed literature, particularly in top-ranked journals. The problem is not simply one of publishing more, but of knowing how and where to publish. It is urgent that Cuban universities training health professionals at all levels include instruction on scientific writing.

We aimed to map the global scientific research on sexuality and dementia in the elderly to understand the focus and the growth of the area during the past decades. An exploratory study, descriptive and bibliometric with academic works on the database ISI Web of Knowledge/Web of Science (TM). The following descriptors were used: “elder*”, “dementia*” and “sexuality*” in the time-based scratch between 1945 and 2018. The data analysis was performed with the aid of the software HistCite (TM). After applied the filters of refinement, there were identified 79 articles, published in 45 different journals indexed in the database in reference, written by 157 authors linked to 96 research institutions located in 19 countries. To achieve these articles there were used 2,312 references with an average of approximately 32 references per article. The international scientific production about sexuality and dementia in the elderly is scarce, and highlights the need for more specific studies on the theme and its potential for exploitation in future studies.

Noncommunicable Diseases are an important public health issue in Brazil and worldwide. This study aimed to analyze the scientific production published by the “Journal Ciencia & Saude Coletiva” in order to shed light on its contributions for the dissemination of scientific knowledge and the debate regarding noncommunicable diseases. A bibliometric study on the publications from 1996 to 2019 related to noncommunicable diseases was carried out. A total of 458 documents that met the eligibility criteria were selected. An increasing trend in the number of publications per year was found; at some points, it coincided with political and institutional milestones in Brazil. Quantitative research papers stood out, as did studies on risk and protective factors. Public educational and research institutions led the publishing and the financing of the studies. Most authors were female. The journal has been reflecting the magnitude of the theme and its prioritization on the public agenda by promoting the debate and providing a scientific dissemination of content related to noncommunicable diseases.

Research on natural zeolites (NZ) has increased over the years, showing potential in different areas, and many of them involve cation exchange (CE), considered one of the essential properties of NZ. This work aims to identify studies’ cognitive structure based on the cation exchange capacity (CEC) of NZ through bibliometric analysis to evaluate scientific production, growth trend, and visualization through bibliometric maps using the VOSviewer software. All types of documents and all languages indexed in Scopus from 1970 to 2020 were considered for the database, obtaining 703 documents. The results indicate an increasing trend in CE annual publications in NZ. This analysis shows the most influential authors such as Dakovic, Wang and Colella, while the countries that stand out are China, Turkey and the United States. Besides, the bibliometric maps made it possible to understand the intellectual structure of this academic discipline, identifying areas of current and potential interest in this field of studies such as its application in medicine, agriculture, catalysts, heavy metal removal, wastewater treatment (WWT), bioremediation and construction. Finally, these studies showed trends in science and technology studies favoring environmental remediation and human health.

This article provides an empirical overview of coffee/caffeine studies in relation to sport worldwide, an incipient but growing relationship that has existed since 1938, although systematized over time since 1999. The extracted articles were examined using a bibliometric approach based on data from 160 records stored in the Web of Science (JCR) between 1938 and August 2021, applying traditional bibliometric laws and using VOSviewer for data and metadata processing. Among the results, these articles highlight an exponential increase in scientific production in the last two decades, with a concentration in only 12 specific journals, the hegemony of the USA among the co-authorship networks of worldwide relevance, and the thematic and temporal segregation of the concepts under study. This article concludes a high fragmentation of the authors with the highest level of scientific production and an evolution of almost 20 years in relevant thematic topics, and a concurrent concentration in three large blocks: (1) coffee consumption and risk factors, (2) health and coffee consumption, and (3) metabolism and sport correlated with the intake of coffee, which are distanced in time, providing evidence of an evolution that gives way to the irruption of alternative visions in the relationship of coffee and caffeine with sport.

Objective: To describe and evaluate the xylitol products’ applicability and its effects in the health area worldwide utilizing a bibliometric analysis from randomized controlled trials (RCT) with humans. Material and Methods: Electronic searches were carried out in Medline/PubMed, Scopus, Cochrane Library, Web of Science, and VHL databases. The main data extracted were: year, area of applicability, type of treatment, country, journal, xylitol posology and concentration, presentation form, outcomes, and effects. Results: From 1476 studies, 257 were included. These studies were published between 1973-2021. The majority was carried out in dentistry (78.9%) and under preventive treatment (67.4%). These studies were developed in the USA (15.4%) and published in Caries Research (6.6%). The posology and concentration ranged between 0.004-67 g/day and 0.002-100%, respectively. The xylitol is usually used in the chewing gum form (44.0%), and for antimicrobial activity evaluation (38.5%). A positive effect was observed in 204 studies (79.3%) and was associated with xylitol concentration >= 15% (p=0.007). Side effects were reported in 8.2% and were associated with posology >= 5 g/day (p=0.05). Conclusion: Most studies with xylitol were conducted to prevent diseases in the dentistry field. The chewing gum form and antimicrobial activity evaluation were more frequent. Most xylitol products have a positive effect, and few studies report side effects.
