Bibliometric and social network analysis of a Clinical and Translational Resource awardee: An Oklahoma experience 2014-2021.

Background: Social Network Analysis is a method of analyzing coauthorship networks or relationships through graph theory. Institutional Development Award (IDeA) Networks for Clinical and Translational Research (IDeA-CTR) was designed to expand the capability for clinical and translational research to enhance National Institutes of Health funding. Methods: All publications from a cohort of clinical and translational scientists in Oklahoma were collected through a PubMed search for 2014 through 2021 in October 2022. For this study's bibliometric portion, we pulled the citations from iCite in November of 2022. Results: There were 2,391 articles published in 1,019 journals. The number of papers published by year increased from 56 in 2014 to 448 in 2021. The network had an average of 6.4 authors per paper, with this increasing by year from 5.3 in 2014 to 6.9 in 2021. The average journal impact factor for the overall network was 7.19, with a range from 0.08 to 202.73. The Oklahoma Shared Clinical and Translational Resources (OSCTR) network is a small world network with relatively weak ties. Conclusions: This study provides an overview of coauthorship in an IDeA-CTR collaboration. We show the growth and structure of coauthorship in OSCTR, highlighting the importance of understanding and fostering collaboration within research networks.

Bibliometric insights into microalgae cultivation in wastewater: Trends and future prospects for biolipid production and environmental sustainability.

Cultivation of microalgae in wastewater stream has been extensively reported, especially for simultaneous production of biolipid and wastewater treatment process. This study aimed to derive the research trend and focus on biolipid production from microalgae cultivated in wastewater by using bibliometric approach. The search strategy used in Scopus database resulted in 1339 research articles from 1990 to November 2023. Majority of publications (46%) were affiliated to China and India, showing their predominance in this field. Keywords related to the center of attention included biodiesel, biofuel, biomass and nutrient removal. Meanwhile, keyword with recent publication year, indicating the emerging research trends, revolved around the cultivation techniques and application of the system. Co-culture involving more than one microalgae species, bacteria and yeast showed promising results, while addition of nanoparticles was also found to be beneficial. Increasing exploration on the application of microalgae for treatment of saline wastewater was also reported and the carbon fixation mechanism by microalgae has been widely investigated to promote less environmental impact. Future research on these topics were suggested based on the findings of the bibliometric analyses.

The power of partnership: Exploring collaboration dynamics in U.S. transplant research.

INTRODUCTION: Collaboration is one of the hallmarks of academic research. This study analyzes collaboration patterns in U.S. transplant research, examining publication trends, productive institutions, co-authorship networks, and citation patterns in high-impact transplant journals. METHODS: 4,265 articles published between 2012 and 2021 were analyzed using scientometric tools, logistic regression, VantagePoint software, and Gephi software for network visualization. RESULTS: 16,003 authors from 1,011 institutions and 59 countries were identified, with Harvard, Johns Hopkins, and University of Pennsylvania contributing the most papers. Odds of international collaboration significantly increased over time (OR 1.03; p â€‹= â€‹0.040), while odds of citation in single-institution collaborations decreased (OR 0.99; p â€‹= â€‹0.016). Five major scientific communities and central institutions (Harvard University and University of Pittsburgh) connecting them were identified, revealing interconnected research clusters. CONCLUSIONS: Collaboration enhances knowledge exchange and research productivity, with an increasing trend of institutional and international collaboration in U.S. transplant research. Understanding this community is essential for promoting research impact and forming strategic partnerships.

Alcohol, cardiovascular disease and industry funding: A co-authorship network analysis of epidemiological studies.

INTRODUCTION: Alcohol's effects on cardiovascular disease (CVD) are controversial. Alcohol industry actors have shown particular interest in this subject, and been extensively involved through research funding, and in other ways, generating concerns about bias, particularly in reviews. MATERIAL & METHODS: We conducted a co-authorship network analysis of the primary studies included within a previous co-authorship study of 60 systematic reviews on the impact of alcohol on CVD. Additionally, we examined the relationships between declared alcohol industry funding and network structure. RESULTS: There were 713 unique primary studies with 2832 authors published between 1969 and 2019 located within 229 co-authorship subnetworks. There was industry funding across subnetworks and approximately 8% of all papers declared industry funding. The largest subnetwork dominated, comprising 43% of all authors, with sparse evidence of substantial industry funding. The second largest subnetwork contained approximately 4% of all authors, with largely different industry funders involved. Harvard affiliated authors who at the review level formed co-authorship subnetworks with industry funded authors were seen at the primary study level to belong to the largest epidemiological subnetwork. A small number of key authors make extensive alcohol industry funding declarations. CONCLUSIONS: There was no straightforward relationship between co-authorship network formation and alcohol industry funding of epidemiological studies on alcohol and CVD. More fine-grained attention to patterns of alcohol industry funding and to key nodes may shed further light on how far industry funding may be responsible for conflicting findings on alcohol and CVD.

Comprehensive Analysis of Global Research on Erectile Dysfunction from 2002 to 2021: A Scientometric Approach.

Background: Erectile dysfunction (ED) is a multifaceted yet prevalent male-related sexual dysfunction that manifests as a change in any of the erectile response components, including relational, psychological, and biological. We aimed to use bibliometric analyses to determine how ED research has progressed and define the future trends necessary to contribute to scholarly literature. Methods: Two tools, VOSviewer and MS Excel, were used, and the study was conducted in May 2022. A total of 16,114 records were selected for in-depth analyses. We examined the most eminent authors, highly cited papers within journals, and the institutions that have provided the greatest number of articles regarding ED, and demonstrated that ED research has increased over the last two decades. Results: The total number of research documents published between 1971 and 2021 was 16,114, with a growth rate of 5%. Montorsi, Maggi, and Mulhall shared the top spot in the number of publications (n = 164). The Journal of Sexual Medicine has the most papers (N = 1839), followed by the International Journal of Impotence Research (N = 780), the Journal of Urology (N = 557), and Urology (N = 489). Conclusion: The study revealed increased ED research in the past two decades, with notable authors and sources identified. The top three countries contributing to ED are the UK, Italy, and the USA. Recommendations include interdisciplinary collaboration, novel therapeutic approaches, addressing psychological and relational factors, conducting longitudinal studies, and publishing in reputable journals. Implementing these can advance understanding, improve treatment options, and enhance ED management.

Drought and sorghum: a bibliometric analysis using VOS viewer.

Drought has emerged as a significant global concern in recent years, leading to a proliferation of research on sorghum, an important drought resistant crop. Consequently, conducting a bibliometric analysis of said publications has the potential to yield insights into current areas of interest and potential avenues for future research. The present study utilized the Web of Science database to gather literature published between the years 2000 and 2022. The search terms 'drought' AND 'sorghum' was employed to identify relevant publications and as a result, 1731 publications were obtained. The bibliometric analysis of the obtained articles was conducted using VOSviewer software (1.6.19). The keyword 'sorghum' was found to have the highest frequency, with a total link strength of 4238. This keyword exhibited a strong association with the terms 'drought' and 'drought tolerance'. The average number of citations for the 100 most-cited articles was 509.2. The journal Crop Science attained the top position with 60 published articles and secured the highest number of citations with a count of 2795. The academic works of Graeme L. Hammer, comprising 40 articles affiliated with the University of Queensland (UQ), have garnered a total of 3612 citations. Similarly, the same university has produced 112 articles that have been cited 5551 times, thereby establishing it as the most frequently cited organization, with Hammer receiving the highest citation count. UQ had a total of 41 collaborators, with a cumulative link strength of 115. The USA has the highest number of articles pertaining to drought and sorghum. The published literature has focused on abiotic stress tolerance, genetic analysis, and physiological traits, among others. It is anticipated that there will be a substantial rise in the quantity of worldwide publications pertaining to drought and sorghum. The USA offered a significant contribution to this emerging field.Communicated by Ramaswamy H. Sarma.

COVID-19 associated coagulopathy: A bibliometric investigation.

Infection with SARS-CoV-2 initiates an immune-hemostatic response. While both systems are intimately connected and necessary for an efficient immune response to contain the infection, excessive coagulation activation might exceed the valuable benefits by causing thrombotic consequences and excessive inflammation. This biological response is new to clinicians and researchers, and accordingly, tremendous studies have been conducted on coagulopathy and its relationship to COVID-19 disease during this pandemic. Therefore, it takes a research insight from a bibliometric perspective to determine research hotspots and trends of COVID-19 associated coagulopathy (C19-CA). The analysis relies on the Scopus database for bibliographic content and Visualization of Similarities viewer software to map bibliometric data of C19-CA. Our study finds the most eminent authors, journals, institutions, funding organizations, and countries that publish in the C19-CA. Additionally; this research employs bibliometric analysis of co-authorship, co-citations, bibliographic coupling, and co-occurrence of keywords. A total of 2242 studies were retrieved, and the number of annual publications of C19-CA showed remarkable growth. The top-publishing authors on C19-CA are Smadja, D.M., Diehl, J.L., and Gendron, N (France). The total number of articles published in English in these three years was 1241, with the original article accounting for 99.8% and conference papers accounting for 0.2%. Huazhong University of Science and Technology (China) is the top-productive institution, with the US being the top-publishing country. Journal of Thrombosis and Thrombolysis received the highest number of original articles. The research results were mainly published in the fields of Medicine, Biochemistry, Genetics, and Molecular Biology, Immunology and Microbiology. Yuanyuan Li, who is (China), is the top-collaborating author. China and its authors have the highest number of citations. Keywords' co-occurrence analyses of the authors and all keywords revealed the following themes in C19-CA; abnormal coagulation parameters, pulmonary coagulopathy, venous and arterial thrombotic disorders, distinct features of coagulopathy, inflammation, and thrombosis in COVID-19, and anticoagulants and thrombolytic therapies. By combining bibliometric analysis with VOSviewer software, we identified C19-CA's leaders, collaborating institutions, and research hotspots, as well as give references for future research paths.

Roles, outcomes, and enablers within research partnerships: A rapid review of the literature on patient and public involvement and engagement in health research.

BACKGROUND: Recent studies mention a need to investigate partnership roles and dynamics within patient and public involvement and engagement (PPIE) in health research, and how impact and outcomes are achieved. Many labels exist to describe involvement processes, but it is unknown whether the label has implications on partnerships and outcomes. This rapid review investigates how roles between patients, relatives and researchers in a broad variety of PPIE activities in health research are described in peer reviewed papers and explores what enables these partnerships. METHODS: Rapid review of articles published between 2012 and February 2022 describing, evaluating, or reflecting on experiences of PPIE in health research. All research disciplines and research areas were eligible. Four databases (Medline, Embase, PsychInfo and CINAHL) were searched between November 2021 and February 2022. We followed PRISMA guidelines and extracted descriptive factors: year, origin, research area and discipline, study focus, framework used and co-authorship. On a selection of articles, we performed a narrative analysis of partnership roles using Smits et al.'s. Involvement Matrix. Lastly, we performed a meta synthesis of reported enablers and outcomes of the partnerships. Patients and Relatives (PRs) have been involved in the whole rapid review process and are co-authors of this article. RESULTS: Seventy articles from various research disciplines and areas were included. Forty articles were selected for a narrative analysis of the role description of PRs and researchers, and a meta synthesis of enablers and outcomes. Most articles described researchers as decision-makers throughout the research cycle. PRs most often were partners when they were included as co-authors; they were mostly partners in the design, analysis, write-up, and dissemination stages. Enablers of partnerships included: PR training, personality of PRs and communication skills, trust, remuneration and time. CONCLUSIONS: Researchers' decision-making roles gives them control of where and when to include PRs in their projects. Co-authorship is a way of acknowledging patients' contributions which may lead to legitimation of their knowledge and the partnership. Authors describe common enablers, which can help future partnership formation.

This article investigates how other articles describe the roles patients, relatives and researchers have in patient and public involvement activities in health research. It also investigates which factors are supportive of creating these research partnerships. We searched four health research databases and found 70 relevant articles which somehow evaluated patient involvement activities in research. From these 70 articles we chose 40 which we closely investigated for descriptions of roles in the partnerships between researchers and patients and relatives. For this, we used a tool called the Involvement Matrix which uses five different roles: Listener (who is given information), Co-thinker (who is asked to give opinion), Advisor (who gives (un)solicited advice), Partner (who works as an equal partner) and Decision-maker (Who takes initiative and (final) decisions). We found that it is often researchers who take on the role of Decision-maker and that involvement often happens on their terms. We noticed that patients and relatives most often had the role of partner, when they were listed as co-authors of the article. This shows co-authorship as an authorization of their work during patient and public involvement activities. We found that patient and relative training, patients' and relatives' personality and communication skills, trust, financial reimbursement, and time were mentioned most often as enablers of good research partnerships.

Exploring high scientific productivity in international co-authorship of a small developing country based on collaboration patterns.

The number of published scientific paper grows rapidly each year, totaling more than 2.9 million annually. New methodologies and systems have been developed to analyze scientific production and performance indicators from large quantities of data available from the scientific databases, such as Web of Science or Scopus. In this paper, we analyzed the international scientific production and co-authorship patterns for the most productive authors from Serbia based on the obtained Web of Science dataset in the period 2006-2013. We performed bibliometric and scientometric analyses together with statistical and collaboration network analysis, to reveal the causes of extraordinary publishing performance of some authors. For such authors, we found significant inequality in distribution of papers over journals and countries of co-authors, using Gini coefficient and Lorenz curves. Most of the papers belong to multidisciplinary, interdisciplinary, and the field of applied sciences. We have discovered three specific collaboration patterns that lead to high productivity in international collaboration. First pattern corresponds to mega-authorship papers with hundreds of co-authors gathered in specific research groups. The other two collaboration patterns were found in mathematics and multidisciplinary science, mainly application of graph theory and computational methods in physical chemistry. The former pattern results in a star-shaped collaboration network with mostly individual collaborators. The latter pattern includes multiple actors with high betweenness centrality measure and identified brokerage roles. The results are compared with the later period 2014-2023, where high scientific production has been observed in some other fields, such as biology and food science and technology.

Gender gaps in Australian research publishing, citation and co-authorship.

Despite improvement in gender inequality in Australian science, the problem has not been fully addressed yet. To better understand the nature of gender inequality in Australian science, all gendered Australian first authored articles published between 2010 and 2020 and indexed in the Dimensions database were analysed. Field of Research (FoR) was used as the subject classification of articles and Field Citation Ratio (FCR) was used for citation comparison. Overall, the ratio of female to male first authored articles increased over the years, and this was true for all FoRs except for information and computing sciences. The ratio of single-authored articles by females was also improved over the study period. Females appeared to have a citation advantage, using Field Citation Ratio, over males in a few FoRs including mathematical sciences, chemical sciences, technology, built environment and design, studies in human society, law and legal studies, and studies in creative arts and writing. The average FCR for female first authored articles was greater than the average FCR for male first authored articles, including in a few fields such mathematical sciences where male authors outperformed females in terms of the number of articles.

Textile waste water treatment: analysis of mapping knowledge domains.

Textile waste water contains dyes and chemicals that produce harmful vapors and exhaust gases, which is hazardous to the environment and public health. Therefore, it must be carefully treated before discharged. To understand the research evolution in the research area of textile waste water treatment, based on bibliometrics, an in-depth analysis of the publications and hotspots in this area was presented in this paper. For the analysis, totally 6774 papers related to the research area that are published between the year 1964 and 2023 were collected from the Web of Science Core Collection. Using CiteSpace and VOSviewer as bibliometric analysis tools, the collaboration of countries, regions, and organizations was investigated. Besides, an analysis for citation and co-citation of journals, authors, references, and co-occurrence of keywords was performed. The evolution of research hotspots in the three major research directions related to degradation, oxidation, and adsorption is also analyzed in this paper. The analysis results show that researches related to oxidation and adsorption are active in recent years, while nanocomposite adsorbents and graphene oxide are the current research hotspots.

Global trends in research of achilles tendon injury/rupture: A bibliometric analysis, 2000-2021.

Background: The Achilles tendon is the strongest and most susceptible tendon in humans. Achilles tendon injuries and ruptures have gradually attracted research attention. However, a bibliometric analysis of global research in this field is lacking. This study involved a bibliometric analysis of the developmental trends and research hotspots in Achilles tendon injuries/ruptures from 2000 to 2021. Methods: Articles published between 2001 and 2021 were retrieved from an extended database of the Science Citation Index using Web of Science. VOSviewer and CiteSpace were used to analyze the relationships between publications, countries, institutions, journals, authors, references, and keywords. Results: This study included 3,505 studies of 73 countries, 3,274 institutions, and 12,298 authors and explored the cooperation between them and the relationships between citations. Over the past 22 years, the number of publications has significantly increased. Foot Ankle International has published the most papers on Achilles tendon injuries/ruptures, and British Journal of Sports Medicine is the most famous journal. Re-rupture, exosomes, acute Achilles tendon rupture, and tendon adhesions gradually become the research focus over the past few years. Conclusion: Achilles tendon injury and rupture are important research topics. A vast number of newly published papers on this topic have demonstrated that clinicians and researchers are interested in their study. Over time, these recent studies will be widely cited; therefore, this bibliometric analysis should be constantly updated.

Sustainable management of food waste; pre-treatment strategies, techno-economic assessment, bibliometric analysis, and potential utilizations: A systematic review.

Food waste (FW) contains many nutritional components such as proteins, lipids, fats, polysaccharides, carbohydrates, and metal ions, which can be reused in some processes to produce value-added products. Furthermore, FW can be converted into biogas, biohydrogen, and biodiesel, and this type of green energy can be used as an alternative to nonrenewable fuel and reduce reliance on fossil fuel sources. It has been demonstrated in many reports that at the laboratory scale production of biochemicals using FW is as good as pure carbon sources. The goal of this paper is to review approaches used globally to promote turning FW into useable products and green energy. In this context, the present review article highlights deeply in a transdisciplinary manner the sources, types, impacts, characteristics, pre-treatment strategies, and potential management of FW into value-added products. We find that FW could be upcycled into different valuable products such as eco-friendly green fuels, organic acids, bioplastics, enzymes, fertilizers, char, and single-cell protein, after the suitable pre-treatment method. The results confirmed the technical feasibility of all the reviewed transformation processes of FW. Furthermore, life cycle and techno-economic assessment studies regarding the socio-economic, environmental, and engineering aspects of FW management are discussed. The reviewed articles showed that energy recovery from FW in various forms is economically feasible.

A Bibliometric Analysis of the Journal of Religion and Health: Sixty Years of Publication (1961-2021).

The year 2021 marked the 60th anniversary of the founding of JORH. This research paper retrospectively analyses the journal's content. It provides insight into JORH's publication trends, citation records, prominent themes, authors' collaboration and its aggregate contribution to the field of religion and health. Over time, the number of publications, citations and downloads of JORH articles have substantially increased, as has the journals prominence and diverse contributions to the study of religion, spirituality and health.

Analysis of scientific production aligned with the Food and Nutrition Security Strategy of Portuguese-Speaking African Institutions: a systematic scoping review / Análise da produção científica alinhada com a Estratégia de Segurança Alimentar e Nutricional das Instituições Africanas de Língua Portuguesa: uma revisão sistemática de escopo

ABSTRACT This systematic scoping review aimed to map and characterize the scientific production of researchers from Portuguese-speaking African institutions that align with the Food and Nutrition Security Strategy of the Community of Portuguese-Speaking Countries. The literature search was conducted using six electronic databases (PubMed, EMBASE, Virtual Health Library, Scientific Electronic Library Online, Scopus, and Web of Science), with no restrictions on the year of publication nor language. Through the search strategy, 10,061 records were identified, of which 502 documents and 654 researchers were selected by Food and Nutrition Security specialists along three axes: 1) Policy governance; 2) Access to food; 3) Availability of food. Institutional researchers from Mozambique (66.9%), Guinea-Bissau (15.9%), and Angola (11.4%) presented the most publications and international collaborations. Researchers from Cape Verde, Sao Tome and Principe, and Equatorial Guinea institutions added only 5.8% of the total production. A greater number of publications (61%) was related to axis two of the Food and Nutrition Security Strategy of the Community of Portuguese-Speaking Countries. The most studied themes were sustainable development, child malnutrition, and agricultural production for the first, second, and third axis, respectively. In general, scientific publications have shown limitations in their approaches due to the challenge imposed by the complexity of the food system. However, there has been a quantitative evolution in publications in the last decade, with a greater participation of researchers from Portuguese-speaking African institutions.

RESUMO Esta revisão sistemática de escopo teve como objetivo mapear e caracterizar a produção científica de pesquisadores de instituições africanas de língua portuguesa que se alinham com a Estratégia de Segurança Alimentar e Nutricional da Comunidade dos Países de Língua Portuguesa. A busca das literaturas foi realizada em seis bases de dados eletrônicas (PubMed, EMBASE, Biblioteca Virtual em Saúde, Scientific Electronic Library Online, Scopus e Web of Science), sem restrição quanto ao ano de publicação e ao idioma. Por meio da estratégia de busca, foram identificados 10.061 registros, dos quais 502 documentos e 654 pesquisadores foram selecionados por especialistas em Segurança Alimentar e Nutricional em três eixos: 1) Governança de políticas; 2) Acesso à alimentação; 3) Disponibilidade de alimentos. Pesquisadores de intuições de Moçambique (66,9%), Guiné-Bissau (15,9%) e Angola (11,4%) foram os que apresentaram o maior número de publicações e colaborações internacionais. No entanto, os pesquisadores das instituições de Cabo Verde, São Tomé e Príncipe e Guiné Equatorial somaram apenas 5,8% da produção total. Foi observado maior número de publicações (61%) relacionadas com o eixo dois da Estratégia de Segurança Alimentar e Nutricional da Comunidade dos Países de Língua Portuguesa. As temáticas mais estudadas foram desenvolvimento sustentável, desnutrição infantil e produção agrícola para o primeiro, segundo e terceiro eixo, respectivamente. De forma geral, as publicações científicas mostraram limitações em suas abordagens frente ao desafio imposto pela complexidade do sistema alimentar. Todavia, foi houve uma evolução quantitativa nas publicações na última década; além disso, maior participação de pesquisadores de instituições africanas de língua portuguesa pode ser vislumbrada.

Disparidade de Gênero na Autoria Principal e Sênior em Periódicos Brasileiros de Cardiologia / Gender Disparity in First and Senior Authorship in Brazilian Cardiology Journals

Resumo Fundamento: Apesar da importância das mulheres na pesquisa clínica, não existe uma avaliação da fração de mulheres em posições de autoria nos periódicos de cardiologia da SBC. Objetivos: Avaliar a fração de mulheres autoras na International Journal of Cardiovascular Sciences (IJCS) e nos Arquivos Brasileiros de Cardiologia (ABC Cardiol) nas últimas décadas. Métodos: Realizamos busca dos artigos originais dos ABC Cardiol, entre 2000 e 2019, e da IJCS, entre 2010 e 2019. Foi feito levantamento do número de primeiras e últimas autoras e do total de artigos originais de 2010 a 2019. Calculamos as proporções totais de autorias femininas e comparamos o primeiro quinquênio com o segundo. Para avaliar a evolução temporal das duas décadas, analisamos apenas dados dos ABC Cardiol. Utilizamos o teste Qui-quadrado para analisar as diferenças dentro de cada revista e entre ambas. O software IBM® SPSS® foi utilizado nas análises. O nível de significância adotado foi de 5%. Resultados: De 2010 a 2019, foram publicados 1157 artigos originais nos ABC Cardiol e 398 na IJCS. Observamos que as mulheres têm maior predominância como primeiras autoras na IJCS em relação aos ABC Cardiol, mas os homens predominam como últimos autores em ambos. De 2010 a 2019, não houve modificação significativa na proporção de autorias femininas. Ao longo das décadas analisadas para os ABC Cardiol, houve projeção de crescimento linear de autorias femininas, sendo que a inclinação da reta é maior na projeção da primeira autoria que na autoria sênior. Conclusões: Há disparidade de gênero com menor representatividade feminina nas autorias dos artigos dos periódicos cardiológicos brasileiros analisados: Arquivos Brasileiros de Cardiologia e International Journal of Cardiovascular Sciences. Acreditamos que a partir destes resultados mais esforços devam ser implementados em busca de equidade de gênero na produção científica cardiológica veiculada por estes periódicos.

Abstract Background: Despite the importance of women in clinical research, no assessment has been made of the fraction of women in a leadership positions in the Cardiology journals of the SBC. Objectives: To assess the fraction of female authors in the International Journal of Cardiovascular Sciences (IJCS) and the Arquivos Brasileiros de Cardiologia (ABC Cardiol) over the last decades. Methods: We searched the original articles of the ABC Cardiol, from 2000 to 2019, and of the IJCS, from 2010 to 2019. We surveyed the number of first and senior female authors and the total number of original articles from 2010 to 2019. We calculated the total proportion of female authorship and compared the first quinquennium with the second. Only data from the ABC Cardiol were analyzed to assess the temporal evolution of the two decades. We used the chi-square test to assess the differences within each journal and between them. The IBM® SPSS® software was used in the analyses. The level of significance adopted was 5%. Results: From 2010 to 2019, 1,157 original articles were published in the ABC Cardiol and 398 in the IJCS. We observed that women are more prevalent as first authors in the IJCS compared to the ABC Cardiol, but men prevail as senior authors in both journals. From 2010 to 2019, there was no significant change in the proportion of female authorship. Throughout the decades analyzed for the ABC Cardiol, there was a projection of linear growth of female authorship, with the slope of the line being greater in the first authorship than in senior authorship. Conclusions: There is gender disparity, with lower female representativeness in authorship in the articles from the Brazilian Cardiology journals analyzed: Arquivos Brasileiros de Cardiologia and International Journal of Cardiovascular Sciences. We believe that based on these results, more efforts should be implemented in the search for gender equity in the cardiology scientific production published by these journals.

Publication landscape of Posterior urethral valve- A scientometric study.

To assess the global research landscape in the field of Posterior urethral valve (PUV), a scientometric study was conducted to determine the quantity and quality of the research output and get insight into the key research areas and pattern of collaboration in the research community. METHODS: Primary data was acquired from the Scopus® database. Various parameters like the total research productivity, citations, citations per publication, citations per year, citations per publication per year, the scientific output of countries, institutions, authors, and journals were calculated. Key research areas were inferred by examining the top-cited articles (citations >150). Collaborative maps were generated by calculating co-authorship links amongst countries and authors using VOSviewer software. RESULTS: One thousand seven hundred fourteen results were found published from 1913 to 2019, receiving a total of 27,253 citations, authored by 5138 authors from 125 countries. The top three countries were the United States of America (USA), India, and the United Kingdom (UK). The leading institutes were the Children's Hospital Boston, USA (n = 48), All India Institute of Medical Sciences (AIIMS, Delhi), India (n = 38), and Great Ormond Street Hospital, UK (n- = 27). The journals which published the most articles on PUV were the Journal of Urology (n = 278), Journal of Pediatric Urology (n = 121), followed by Urology (n = 86). Leading authors were Glassberg, K. L and Bajpai M (n = 17, each), Canning DA & Kajbafzadeh, AM (n = 16, each), followed by Peters CA with 14 manuscripts. The top-cited documents (n = 10) received 2104 citations and were published between 1986 and 2010. The key areas of interest found were "long-term outcomes" (n = 4) and "fetal surgery" (n = 2). The most productive countries were also the most collaborative countries (the USA and UK). CONCLUSION: In the research landscape of PUV, the USA, Children's Hospital Boston, and Glassberg, K. L, along with Bajpai, M were the top contributors in terms of the country, organization, and authors, respectively. The "Journal of Urology" and "Pediatric Nephrology" stands out in terms of bibliometric parameters considered. The hotspot topics based on the number of citations received were "long-term outcomes" and "fetal surgery" in PUV. The most productive countries were also the most collaborative countries (the USA and UK).

Global network mapping research landscape and trends of the endogenous retroviruses: a look through bibliometric analysis.

Endogenous retrovirus (ERV) research amalgamates host-retroviral coevolutionary, phylogenomic, infection, immunity, and cellular studies in various hosts ranging from fish to humans. Henceforth, a bibliometric analysis of these publications may aid in the identification of trends in ERV research. It was the foremost bibliographic study, with the key aim to conduct the bibliometric network analysis (e.g. co-authorship, co-occurrence, citation, bibliographic coupling, and co-citation analysis) to find the most prolific authors, organizations, and countries in ERV research, based on the mapping of bibliographic data. Second, the mapping based on text data comprised to chalk out the research trend over the time. The global literature about endogenous retroviruses published between 1985 and Sep 2021 was searched in the Web of Science (Core Collection) database using the "ENDOGENOUS RETROVIRUS" keyword. The bibliometric analysis of this dataset was carried out using VOSviewer version 1.6.17. According to findings, English was the de facto language of these publications, and 2157 were original articles. Among 2939 published documents, "endogenous retrovirus" was the most frequent keyword. Moreover, it revealed the United States as a core contributor to studies on the ERV. The Journal of Virology published a substantial amount of manuscripts in ERV. Robert Koch Institute and Harvard University were leading organizations for research in this field. The application of ERV research from China could be the research hotspot to follow in the coming years. Current bibliometric analysis provides a comprehensive picture of ERV research progress and has highlighted the contribution of different stakeholders.

Scientometric analysis and identification of research trends in microplastic research for 2011-2019.

Microplastic pollution of our environment has seen major data reporting in the last decade. Microplastics produce harmful effects on marine organisms and in humans. Despite the fact that microplastics (MPs) have inert or sublethal toxicity in many circumstances, their long-term presence can have negative ecological consequences. However, there is a paucity of comprehensive literature on the present study and future development trend of MPs in aquatic ecosystems, to our knowledge. In this scientometric study, the literature was evaluated between years 2011 and 2019. The data show increasing importance of microplastics in terms of increase in publication in concurrence of granting funds in this area by major funding agencies. Most research articles were published by authors (~ 49%) affiliated with Chinese Academy of Sciences. Journals 'Marine Pollution Bulletin' and 'Environmental Pollution' were identified as important journals with 273 and 185 research publications, respectively. We have also identified the upcoming research trend and shift from microplastic presence in water to microplastic presence in air. However, in the year 2017, researchers from the UK started publishing more articles in this field with 11 publications with top authors affiliated to University of Plymouth. The journal Environmental Pollution has been found to be the leading journal (~ 20%) addressing the issue of microplastics in the environment. Our co-authorship analysis demonstrated that China (its institutions and authors) is the most collaborative country followed by the USA, together forming top cluster with a link strength of 42. Finally, our analysis provides information about prospective research and emerging trends that can be explored in the coming years.
