RESUMO

BACKGROUND: The five BRICS (Brazil, Russian, Indian, China and South Africa) countries bear a significant proportion of the world's global cancer burden. AIM: The aim of this paper is to map the scientific landscape related to colorectal cancer (CRC) research published related to South Africa (SA) and Brazil (BRA). METHODS: We used the bibliometric analysis technique to identify and map the scientific publications on CRC related to SA and BRA. We identified the document type, authors, research organisations, countries, funding sources, most relevant journals, research areas, citation reference counts, journal impact factor (IF) and open access designations in CRC scientific landscape for both countries. We analysed publications from January 2000 to August 2020 as indexed in the Web of Science Core Collection, most covering scientific medical related research and used descriptive statistical data analysis to synthesise the data. FINDINGS: During the period 2000-2020, there were 80 and 176 peer-reviewed publications on CRC related to SA and BRA, respectively. The majority were original research articles. Sixty-six percent identified had a primary (first) author affiliated to SA research institution and 87% had primary author affiliated to the BRA research institution. Overall, 275 authors published CRC related to SA and 1,025 authors published CRC related to BRA. The leading research organisation in SA was the University of Witwatersrand (Wits, 26%) and was the University of Sao Paulo (23%) for in BRA. The publications, related to both countries, mostly focused on oncology. The South African Medical Journal (10%) produced the most articles for SA with IF = 1.285; and the Value in Health (7%) for BRA with IF = 1.736. The median cited reference count was 32 for SA publications and 34 for BRA publications. There were 49% and 39% of publications without any open access designations for SA and BRA, respectively. CONCLUSIONS: Mapping CRC scientific publications highlighted potential benefits of developing an informed CRC national research plan in each country to promote concerted effort to better understand the risk factors, treatment and advocate for funding as stimulus for increased CRC research outputs that can inform policy development and influence practice to help reduce and control the CRC burden in both countries.

RESUMO

BACKGROUND The five BRICS (Brazil, Russian, Indian, China, and South Africa) countries bear 49% of the world's tuberculosis (TB) burden and they are committed to ending tuberculosis. OBJECTIVES The aim of this paper is to map the scientific landscape related to TB research in BRICS countries. METHODS Were combined bibliometrics and social network analysis techniques to map the scientific publications related to TB produced by the BRICS. Was made a descriptive statistical data covering the full period of analysis (1993-2016) and the research networks were made for 2007-2016 (8,366 records). The bubble charts were generated by VantagePoint and the networks by the Gephi 0.9.1 software (Gephi Consortium 2010) from co-occurrence matrices produced in VantagePoint. The Fruchterman-Reingold algorithm provided the networks' layout. FINDINGS During the period 1993-2016, there were 38,315 peer-reviewed, among them, there were 11,018 (28.7%) articles related by one or more authors in a BRICS: India 38.7%; China 23.8%; South Africa 21.1%; Brazil 13.0%; and Russia 4.5% (The total was greater than 100% because our criterion was all papers with at least one author in a BRICS). Among the BRICS, there was greater interaction between India and South Africa and organisations in India and China had the highest productivity; however, South African organisations had more interaction with countries outside the BRICS. Publications by and about BRICS generally covered all research areas, especially those in India and China covered all research areas, although Brazil and South Africa prioritised infectious diseases, microbiology, and the respiratory system. MAIN CONCLUSIONS An overview of BRICS scientific publications and interactions highlighted the necessity to develop a BRICS TB research plan to increase efforts and funding to ensure that basic science research successfully translates into products and policies to help end the TB epidemic.

RESUMO

The aim of this paper is to map the scientific landscape related to cancer research worldwide between 2012 and 2017. We use scientific publication data from Web of Science Core Collection and combine bibliometrics and social network analysis techniques to identify the most relevant journals, research areas, countries and research organizations in cancer scientific landscape. The results show: Oncotarget as the journal with most publications; a significant increase in China's publications, reaching United States' publications in 2017; MD Cancer Center, University of California and Harvard University as organizations with most publications; cell biology as the most frequent research area; breast, lung and colorectal cancer as the most frequent keywords; high density of co-authorship between organizations in the West, especially in the US, and low density between organizations in Asian and lower and medium income countries. Our findings can be used to guide a global knowledge platform guiding policy, planning and funding decisions as well as to establish new institutional collaborations.

RESUMO

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 Fundação 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.
