RESUMO

Abstract Introduction: Bibliometric analyses of research in Sri Lanka, a lower-middle income island nation in South Asia, has focused mainly on medical research, concluding that there is a need for increased research productivity and impact, and for local solutions to health concerns. There has been no general bibliometric analysis across scientific disciplines in the nation, or any study that covers a long period of time to identify general time trends. Objective: To measure and analyse Sri Lanka research by focusing on subjects, authors, institutions, journals and citation for half a century. Methods: We used an advanced search method to extract publications with the word "Sri Lanka" in the SCI-EXPANDED, and calculated indicators such as total citations from Web of Science Core Collection since publication year to the end of 2019, citations in 2019, and mean citations per publication. Journal data were taken from 2019 Journal Citation Report. Affiliation re-classification was done to ensure consistency regarding the origin of all publications. Publications were further analysed based on collaboration, and first and corresponding authorship. Results: We retrieved 16 069 publications in 19 document types (77 % articles). Corrections had the highest number of authors per publication (616) followed by articles (116). Four articles had more than 5 000 authors and 593 articles had more than 1 000 authors. The highest citations in this database were for international megaprojects where Sri Lanka authors played minor roles. The UK had the most collaborative articles with Sri Lanka (19 %). The articles were published in 3 051 journals across 177 Web of Science categories. The category of Public, environmental and occupational health, with 193 journals, had 6.7 % of all articles, followed by environmental sciences (6.6 %). Conclusion: Sri Lanka has an unusually strong pattern of participating as small role players in international megaprojects about health and physics. Sri Lanka authors should be encouraged to expand their horizons by researching non-applied fields that are the basis of all innovation; to strengthen their own journals so that they have better visibility and impact, and to improve their positions in international projects that are published in larger journals.


Resumen Introducción: Los análisis bibliométricos de la investigación en Sri Lanka, una nación insular de ingresos mediano-bajos en el sur de Asia, se han centrado principalmente en la investigación médica, concluyendo que existe la necesidad de aumentar la productividad y el impacto de la investigación, y de soluciones locales a los problemas de salud. No ha habido un análisis bibliométrico general de disciplinas científicas o algún estudio que cubra un período largo de tiempo para identificar tendencias generales. Objetivo: Medir y analizar la investigación de Sri Lanka centrándose en temas, autores, instituciones, revistas y citas, durante medio siglo. Métodos: Utilizamos un método de búsqueda avanzada para extraer publicaciones con las palabras "Sri Lanka" en el SCI-EXPANDED, y calculamos indicadores como el total de citas de Web of Science Core Collection desde el año de publicación hasta finales de 2019, citas solo en 2019, y media de citas por publicación. Los datos de revistas son del Journal Citation Report 2019. Revisamos manualmente las afiliaciones para garantizar su coherencia, y, de todos los tipos de publicación, analizamos en detalle los artículos en función de la colaboración y la autoría. Resultados: Hallamos 16 069 publicaciones en 19 tipos de documentos (77 % artículos). Las correcciones tuvieron el mayor número de autores por publicación (616), seguidas de los artículos (116 autores en promedio); cuatro artículos tenían más de 5 000 autores y 593 artículos tenían más de 1 000 autores. Las citas más altas en esta base de datos fueron para megaproyectos internacionales en los que los autores de Sri Lanka desempeñaron papeles menores. El Reino Unido tuvo más artículos colaborativos con Sri Lanka (19 %). Los artículos se publicaron en 3 051 revistas de 177 categorías del Web of Science. La categoría d Salud pública, ambiental y ocupacional, con 193 revistas, tuvo el 6.7 % del total de artículos, seguida de Ciencias ambientales (6.6 %). Conclusión: En Sri Lanka hay una tendencia inusual a participar como pequeños actores en megaproyectos internacionales sobre salud y física. Debería alentarse a quienes hacen ciencia en Sri Lanka a ampliar sus horizontes investigando campos no aplicados, que son la base de la innovación; a fortalecer sus propias revistas para lograr mayor visibilidad e impacto, y a mejorar su ubicación en proyectos internacionales que se publican en revistas más grandes.

RESUMO

Abstract Introduction: Sudan is the third largest country in Africa and has rich reserves of petroleum and other ground resources, but its per capita Gross Domestic Product is only $808 and researchers work in insufficient institutional facilities and with little funding. Previous studies about its scientific productivity have been limited to specific subjects and relatively short periods, with no large analyses until now. Objective: To analyze the scientific output of Sudan in depth, considering all research areas and several decades of scientific activity. Methods: We retrieved the documents with "Sudan" in field country in the Science Citation Index Expanded for the period 1900-2019. Results: We retrieved over 9 000 publications and found that most were articles; that citation was higher for review articles and book chapters, and that this index mostly covered articles in English. Beginning in 1972, the number of publications in this database has increased rapidly. The citation lifespan indicates slow growth in the Sudanese scientific literature, and collaboration is frequent both nationally and internationally, possibly because the scarce resources make collaboration almost compulsory. Most external collaboration is done with Saudi Arabia but citation is higher for articles resulting from international megaprojects, led by Europe and the USA, in which Sudanese researchers play secondary roles. Research focusses on applied technological subjects with little innovation value. Women play a smaller role in Sudanese science. Conclusions: Our recommendations for Sudanese science include increasing the number of women in leading research positions; providing funding directly to researchers (i.e., bypassing bureaucratic bodies); increasing basic research to avoid stagnation; training Sudanese researchers for leading positions; and identifying specific research areas where Sudan can lead in its region.


Resumen Introducción: Sudán es el tercer país más grande de África y tiene ricas reservas de petróleo y otros recursos terrestres, pero su Producto Interno Bruto per cápita es de solo $ 808 y los investigadores trabajan en instalaciones institucionales deficientes y con poca financiación. Los estudios previos sobre su productividad científica se han limitado a temas específicos y períodos relativamente cortos. Objetivo: Analizar la producción científica de Sudán en profundidad, considerando todas las áreas de investigación y varias décadas. Métodos: Recuperamos los documentos con "Sudán" como país de origen en el Science Citation Index Expanded para el período 1900-2019. Resultados: Hallamos más de 9 000 publicaciones y encontramos que la mayoría eran artículos; que fueron más citados los artículos de revisión y capítulos de libros, y que esta base de datos cubría principalmente artículos en inglés; desde 1972, el número de publicaciones en ella ha aumentado rápidamente. La vida útil de las citas indica un crecimiento lento en la literatura científica sudanesa, y la colaboración es frecuente tanto a nivel nacional como internacional, posiblemente porque los escasos recursos hacen que la colaboración sea casi obligatoria. La mayor parte de la colaboración externa se realiza con Arabia Saudita, pero hay más citas para los artículos resultantes de megaproyectos internacionales, dirigidos por Europa y Estados Unidos, en los cuales los investigadores sudaneses desempeñan papeles secundarios. La investigación se centra en temas de tecnología aplicada con poco valor de innovación. Conclusiones: Nuestras recomendaciones para la ciencia sudanesa incluyen aumentar el número de mujeres en altos puestos; proporcionar financiación directamente a los investigadores (sin pasar por organismos burocráticos); ir más allá de la investigación aplicada para evitar el estancamiento; capacitar al personal sudanés para puestos de liderazgo; e identificar áreas de investigación específicas donde Sudán puede liderar en su región.

RESUMO

Objective: To analyze the literature published in Chinese Journal of Burns (now Chinese Journal of Burns and Wounds) in the last 22 years, and to explore the development trend of burn discipline. Methods: The relevant clinical and research literature published in Chinese Journal of Burns from January 1, 2000 to December 31, 2021 were retrieved through China National Knowledge Infrastructure database. Bibliometrics was used to classify and analyze the literature by research types, involved research fields, and reported causes of injury, and compare them every 3 years according to the year of publication (with literature published in 2021 being included in the last time period). Keywords of all the literature were retrieved, which were corrected and conversed later. CiteSpace 6.1.R2 software was used to visually cluster the included keywords, count high-frequency and high-centrality keywords, and divide the high-frequency keywords by time as before for segment comparison. Results: A total of 4 485 relevant papers were included, with an average of about 204 papers each year. The research types analysis of literature showed that clinical diagnosis and treatment literature had the highest proportion, reaching 65.3% (2 929/4 485), followed by cell experiment and animal experiment literature, accounting for 18.1% (812/4 485) and 13.2% (591/4 485), respectively. The proportion of various research types of the literature in each time period was basically stable. The analysis of the research fields involved in the literature showed that the literature in the field of systemic treatment of burns accounted for the highest proportion, reaching 60.2% (2 699/4 485), followed by the literature in the fields of acute wounds and plastic surgery, accounting for 20.2% (908/4 485) and 7.3% (326/4 485), respectively. The proportion of the literature in the field of systemic treatment of burns decreased from 84.0% (430/512) in 2000-2002 to 40.3% (373/926) in 2018-2021, with a decreasing proportion of 43.7%. While compared with that in 2000-2002, the proportions of literature in the fields of acute wounds, plastic surgery, chronic wounds, and burn rehabilitation were on the rise, with the proportions in 2018-2021 increased by 11.7%, 9.1%, 10.7%, and 5.5%, respectively. In the first 6 time periods, the number of literature in the field of discipline management was few and remained in single digits, but it increased to 49 in 2018-2021. Among the 1 099 literature in the field of systemic treatment of burns with a clear cause of injury, the literature on thermal burns was the most, accounting for 58.5% (643/1 099), followed by the literature on electrical burns and chemical burns, accounting for 19.8% (218/1 099) and 12.6% (138/1 099), respectively. The comparison by time period showed that the proportion of literature reporting thermal burns showed a significant downward trend, while the proportion of literature reporting other causes of injury did not change significantly. A total of 6 822 keywords from 2 236 literature were included for analysis. Visual cluster analysis showed that relevant studies focused on burns, surgical flaps, scars, and wound healing. The top 3 keywords in frequency were burns, wound healing, and surgical flaps, and the top 3 keywords in centrality were burns, scars, and skin transplantation. The comparison by time period showed that the only keyword with a stable frequency in the top 10 ranks was burns; with the passage of time, some keywords such as endotoxin/endotoxins and fibroblasts gradually dropped out of the top 10 ranks, while keywords such as wounds and injuries, surgical flaps, and negative-pressure wound therapy gradually entered the top 10 ranks. Conclusions: Among the literature published in Chinese Journal of Burns during the last 22 years, the literature on systemic treatment of burns and thermal burns has gradually decreased, while the literature on chronic wounds and burn rehabilitation has increased. Surgical flaps, wound healing, and scar prevention and treatment are the current research hot spots in burn discipline.

RESUMO

Background: The emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants with mutations in the spike protein has risen concerns about the efficacy of infection- or vaccine-induced antibodies and has posed a serious threat to global public health, education, travel and economy. Few studies have described the detailed characterizations of highly cited articles on SARS-CoV-2 variants. Objective: To identify and characterize the 100 most-cited articles in SARS-CoV-2 variants research. Design and methods: Articles published recently were extracted from the web of science core collection database using a query based on MeSH terms and topics of SARS-CoV-2 and variants. Characteristics of the 100 most-cited articles were analyzed via the following parameters: publication number over year, number of citations, type of articles, authors, journal, journal impact factor, country, and topics covered in articles. In addition, clinical trials in these articles were also analyzed. Results: The majority of articles (66%) were published in 2021. Number of citations of the 100 most cited articles ranged from 1720 to 75 (median: 178.5). Mutations in the S protein such as D614G mutation and the B.1.1.7 (UK) and B.1.351 (South Africa) were the dominant variants in the 100 most cited articles. The United States, the United Kingdom, and South Africa had the strongest collaboration in the contribution of publication. Science, Cell, Nature and New England Journal of Medicine were mostly cited and the main direction in these top journals were vaccine neutralizing tests and efficacy evaluation studies. Response of antibody neutralization tests against variants was always weakened due to the presence of variants but the results of clinical trials were encouraging. Genomics information, spike protein structure confirmation and neutralization studies evaluating antibody resistance were highly represented in the 100 most cited articles in SARS-CoV-2 variants literature. Conclusions and relevance: Altogether, genomic information, epidemiology, immune neutralization, and vaccine efficacy studies of COVID-19 variants are the main research orientations in these articles and relevant results have been published in influential journals. Given the continuous evolution of the SARS-CoV-2 and the constant development in our understanding of the impact of variants, current working strategies and measures may be periodically adjusted.

RESUMO

OBJECTIVE: With the help of metrology, we can identify research hotspots and development trends in dynamic electrocardiography, and thereby provide corresponding reference material to aid further theoretical research. MATERIALS AND METHODS: All research data derived from the core collection of Web of Science, and all searches were completed on the same day (February 6, 2022). The obtained data were stored in plain text format and imported into CiteSpace for subsequent analysis. Citation analysis and visualization technology were used to draw a visual map of the research elements, using factors such as annual literature volume, country, journal, author, abstract, keywords, and citation. RESULTS: After screening, 2,937 papers were obtained. Research on ambulatory electrocardiography is increasing worldwide every year. Using research hotspots, keyword-clustering time-zone maps, and high-frequency emerging words, the research in this field was roughly divided into two stages, with 2017 as the divider. The first stage primarily focuses on areas such as atrial fibrillation, stroke, autonomic nerve function, catheter ablation, and T-wave alternation. The second stage saw the focus shift to wearable devices, sudden cardiac death, obstructive sleep apnea, feature extraction, cryptogenic stroke, and similar topics. CONCLUSIONS: With the development of various wearable technologies, the daily monitoring of healthy people engaged in sporting activities and the development of innovative analysis algorithms providing more accurate data may represent the hotspots and direction of future research.

RESUMO

BACKGROUND: The number of citations an article receives is a marker of its scientific influence within a particular specialty. This bibliometric analysis intended to recognise the top 100 cited articles in minimally-invasive cardiac surgery, to determine the fundamental subject areas that have borne considerable influence upon clinical practice and academic knowledge whilst also considering bibliometric scope. This is increasingly relevant in a continually advancing specialty and one where minimally-invasive cardiac procedures have the potential for huge benefits to patient outcomes. METHODS: The Web of Science (Clarivate Analytics) data citation index database was searched with the following terms: [Minimal* AND Invasive* AND Card* AND Surg*]. Results were limited to full text English language manuscripts and ranked by citation number. Further analysis of the top 100 cited articles was carried out according to subject, author, publication year, journal, institution and country of origin. RESULTS: A total of 4716 eligible manuscripts were retrieved. Of the top 100 papers, the median (range) citation number was 101 (51-414). The most cited paper by Lichtenstein et al. (Circulation 114(6):591-596, 2006) published in Circulation with 414 citations focused on transapical transcatheter aortic valve implantation as a viable alternative to aortic valve replacement with cardiopulmonary bypass in selected patients with aortic stenosis. The Annals of Thoracic Surgery published the most papers and received the most citations (n = 35; 3036 citations). The United States of America had the most publications and citations (n = 52; 5303 citations), followed by Germany (n = 27; 2598 citations). Harvard Medical School, Boston, Massachusetts, published the most papers of all institutions. Minimally-invasive cardiac surgery pertaining to valve surgery (n = 42) and coronary artery bypass surgery (n = 30) were the two most frequent topics by a large margin. CONCLUSIONS: This work establishes a comprehensive and informative analysis of the most influential publications in minimally-invasive cardiac surgery and outlines what constitutes a citable article. Undertaking a quantitative evaluation of the top 100 papers aids in recognising the contributions of key authors and institutions as well as guiding future efforts in this field to continually improve the quality of care offered to complex cardiac patients.

RESUMO

Background: Autism spectrum disorders (ASD) are heterogeneous neurodevelopmental conditions that affect people worldwide. Early diagnosis and clinical support help achieve good outcomes. However, medical system structure and restricted resource availability create challenges that increase the risk of poor outcomes. Understanding the research progress of childhood ASD in recent years, based on clinical literature reports, can give relevant researchers and rehabilitation therapists more resonable research guides. Objective: This bibliometric study aimed to summarize themes and trends in research on childhood ASD and to suggest directions for future enquiry. Methods: Citations were downloaded from the Web of Science Core Collection database on childhood ASD published from 1 January 2012, to 31 December 2021. The retrieved information was analyzed using CiteSpace.5.8. R3, and VOS viewer. Results: A total of 7,611 papers were published across 103 areas. The United States was the leading source of publications. The clusters that have continued into 2020 include coronavirus disease 2019, gut microbiota, and physical activity, which represent key research topics. Keywords with frequency spikes during 2018-2021 were "disabilities monitoring network," "United States," and "caregiver." Conclusions: The Autism and Developmental Disabilities Monitoring Network in the United States can be used as a reference for relevant workers worldwide. An intelligent medical assistant system is being developed. Further studies are required to elucidate challenges associated with caring for a child with ASD.

RESUMO

Background: There is a crosstalk between traditional Chinese medicine (TCM) and gut microbiota (GM), many articles have studied and discussed the relationship between the two. The purpose of this study is to use bibliometric analysis to explore the research status and development trends of the TCM/GM research, identify and analyze the highly cited papers relating to the TCM/GM. Methods: A literature search regarding TCM/GM publications from 2004 to 2021 was undertaken on August 13, 2022. The main information (full record and cited references) of publications was extracted from the Science Citation Index Expanded (SCI-E) of Web of Science Core Collection (WoSCC). The Bibliometrix of R package, CiteSpace and VOSviewer were used for bibliometric analysis. Results: A total of 830 papers were included. The publication years of papers were from 2004 to 2021. The number of papers had increased rapidly since 2018. China had the most publications and made most contributions to this field. Nanjing University of Chinese Medicine and Beijing University of Chinese Medicine were in the leading productive position in TCM/GM research, Chinese Academy of Chinese Medical Sciences had the highest total citations (TC). Duan Jin-ao from Nanjing University of Chinese Medicine had the largest number of publications, and Tong Xiao-lin from China Academy of Chinese Medical Sciences had the most TC. The Journal of Ethnopharmacology had the most published papers and the most TC. The main themes in TCM/GM included the role of GM in TCM treatment of glucolipid metabolism diseases and lower gastrointestinal diseases; the mechanism of interactions between GM and TCM to treat diseases; the links between TCM/GM and metabolism; and the relationship between GM and oral bioavailability of TCM. Conclusion: This study gained insight into the research status, hotspots and trends of global TCM/GM research, identified the most cited articles in TCM/GM and analyzed their characteristics, which may inform clinical researchers and practitioners' future directions.

RESUMO

Rheumatoid arthritis (RA) is a chronic autoimmune inflammatory disease characterized by macrophage activation. The current characteristics, hotspots, and research frontiers of macrophage-related RA were analyzed using bibliometric analysis. Relatedpapers published from 2000 to 2021 in the Web of Science database were retrieved. The diagrams were generated and analyzed using the bibliometric software package. VOSviewer and CiteSpace were used to evaluate and visualize the research trends and hotspots in macrophage-related RA. A total of 7253 original articles were obtained. Global research on macrophage-related RA is in an advanced stage of development, with core authors, teams and research institutions emerging. United States has published the most papers, received the most citations, and had the highest H-index over the last 22 years. The University of Amsterdam and the journal of Arthritis and Rheumatism are the most productive research institutions and journals. Tak PP's (St Vincent's Hospital) paper has the highest publication and citation scores. The keywords "bone loss" and "polarization" have the highest frequency. Additionally, the study of macrophage polarization in RA has been research focus in recent years. This study demonstrates that research on macrophages in RA will continue. China is a significant producer, whereas the United States is an influential nation in this regard. In the last decade, most studies have concentrated on fundamental research. Recent studies have shown how macrophages play a role in controlling and weakening inflammation, and drug delivery and mechanism have come to the fore.

RESUMO

Bibliometrics is the statistical analysis of scientific publications and trends on a given topic. The use of bibliometric indicators is based on the fact that academic publishing is an essential outcome of research activity, as advancement of science and treatments increases with dissemination of knowledge. Therefore, investigation in our specific field is obligatory, as learning what the current lines of research are can help us to properly orient our research in the coming years. A soon-to-be-published paper analyses 3,027 articles that have appeared in the leading journals of Paediatric Dentistry included in the Journal Citation Reports (JCR): Pediatric Dentistry, the International Journal of Pediatric Dentistry, the European Journal of Paediatric Dentistry and the Journal of Clinical Pediatric Dentistry considering all issues and all articles published from 2008 to 2020. The most frequently addressed topic is surgery (23.4%), which more generally includes pulp treatment, conservative treatments and the use of dental materials (operative dentistry), while the second most discussed topic is prevention (13.2%), followed by oral pathology (10.6%). Subject matters covered less frequently include early childhood caries (ECC) (2.5%) and occlusion (2.7%). In terms of study types, research articles are the most frequently published (74.2%). Among them, the most common study design is observational studies (61.1%), followed by cross-sectional studies (36.9%) and case-control studies (11.9%). With regard to experimental studies, randomised controlled trials (RCTs) are the most common type (11.6%). The number of case series has fallen sharply over time, from 20% 10 years ago to 5% today. Another striking point is that two journals, the International Journal of Pediatric Dentistry and the European Journal of Paediatric Dentistry, have published more than half of the world's output. By looking at the nationality of the authors, it is apparent that research frequently takes place within limited geographical areas, a sign that collaboration between different countries is struggling to take off. Despite the fact that prevention is the second most common topic among the articles analysed in the study-both in absolute terms and also taking into account dental journals focused on different specialties-it still does not play the prominent role it deserves. It is important to emphasise the need for further investigation into the prevention of dental diseases in young patients, as the desired oral health objectives have not yet been achieved. The early identification of risk indicators and the implementation of preventive oral health campaigns aimed at the paediatric population can reduce or prevent the progression of caries, and related expenditures for the replacement of missing teeth at a later age. A final consideration is how interesting it would be to analyse how many of the paediatric medical journals publish papers and articles on paediatric dentistry, as this is in fact another crucial step towards ensuring good oral health for all our young patients!

RESUMO

The world is undergoing an unprecedented trend of fast urbanization, which causes a range of socio-environmental consequences, one of which is shrinking cities and towns (SCT). SCT refer to the cities or towns that are experiencing population decline and economic downturn. In the existing literature, there have been numerous studies on SCT; however, there is a lack of study which investigates its knowledge domains. Therefore, this paper aims to conduct a scientometric analysis to achieve an outline of the SCT research status. Through the procedures of literature search and screening, a total of 716 SCT-related studies were extracted from the Scopus. The VOSviewer software system program was then utilized to visualize the present SCT-related studies. The visualization results revealed that the journal of Sustainability made significant contributions to the SCT research in terms of relevant publications. In addition, Haase, Annegret received the most co-citations, and was also the most productive author in this field. Furthermore, it was identified that current SCT research is mainly conducted in developed countries. Through the analysis of keywords, the emerging research topics were revealed. Discussions were further made from the perspectives of prevailing research methods, evaluation criteria, and solutions for SCT problems.

RESUMO

Cancer has become a major threat to global health care. With the development of computer science, artificial intelligence (AI) has been widely applied in histopathological images (HI) analysis. This study analyzed the publications of AI in HI from 2001 to 2021 by bibliometrics, exploring the research status and the potential popular directions in the future. A total of 2844 publications from the Web of Science Core Collection were included in the bibliometric analysis. The country/region, institution, author, journal, keyword, and references were analyzed by using VOSviewer and CiteSpace. The results showed that the number of publications has grown rapidly in the last five years. The USA is the most productive and influential country with 937 publications and 23,010 citations, and most of the authors and institutions with higher numbers of publications and citations are from the USA. Keyword analysis showed that breast cancer, prostate cancer, colorectal cancer, and lung cancer are the tumor types of greatest concern. Co-citation analysis showed that classification and nucleus segmentation are the main research directions of AI-based HI studies. Transfer learning and self-supervised learning in HI is on the rise. This study performed the first bibliometric analysis of AI in HI from multiple indicators, providing insights for researchers to identify key cancer types and understand the research trends of AI application in HI.

RESUMO

This study aims to map the knowledge structure and themes trends of primary ovarian insufficiency (POI) therapy to help researchers rapidly master the hotspots and prospects of POI therapy from the increasing number of publications. The literature search and bibliometric analyses were performed by using Web of Science Core Collection and VOSviewer. Annual publications from 2000 to 2022 continued to increase with some fluctuations. The most productive country, organization, and journal were the USA, Shanghai Jiao Tong University, and Human Reproduction, respectively. Harvard University was the organization with the highest citation. Fertility and Sterility and Nelson, L.M. were the most influential journal and author, respectively. Seven clusters separated by keywords association showed the extensive scope of POI therapy. The hotspots of POI therapy were hormone replacement therapy and fertility preservation, and the innovative treatment strategies including in vitro activation and mesenchymal stem cells had development potential. In addition, our result showed that the high-cited articles were published in journals with high impact factors. The paper provides a comprehensive overview of the development and hotspots of POI therapy, allowing researchers to recognize the current status and future directions of POI therapy.

RESUMO

The clinical value of the relationship between gastrointestinal microbiome imbalance and its corresponding interventions with kidney disease is emerging. This study describes the hotspots and evolution of gastrointestinal microbiome and kidney disease research over the past three decades by scientific collaboration networks and finally predicts future trends in the field through bibliometric analysis and visualization studies. CiteSpace was used to explore the original articles from January 1990 to August 2021 to visualize the knowledge network of journals, countries, institutions, authors, references, and keywords in this field. Publications were extracted from Web of Science Core Collection database using the terms "gastrointestinal microbiome" and "kidney disease" (and their synonyms in MeSH). A total of 2145 publications with 93880 references in 102 journals were included in the analyses. The number of studies combining gastrointestinal microbiomes with kidney diseases has increased significantly over the past two decades. The United States is the leading country in the number of documents, and the leading institution is the Cleveland Clinic. The most landmark articles in the field are on chronic renal failure, L-Carnitin, and cardiovascular disease. The pathogenesis of uremia toxin is an emerging trend in gastrointestinal microbiomes and kidney diseases. In addition, probiotic or synbiotic supplements have strong clinical value in adjusting abnormal intestinal symbiotic environments. This study demonstrates a growing understanding of the interaction between gut microbiota and kidney disease over time. Using microbial supplements to improve the living conditions of kidney disease patients is a promising and hot research focus. Based on publications extracted from the database, this study may provide clinicians and researchers with valuable information to identify potential collaborators and partner institutions and better predict their dynamic progression.

RESUMO

AIM: To evaluate disparities in the frequency of scientific activity between medical doctors and nurses in Peru. METHODS: We carried out a secondary data analysis of the National Health Services Users' Satisfaction Survey (ENSUSALUD), 2016. This nationally representative survey evaluates doctors and nurses working in clinical settings. We defined scientific activity as i) having published an original article (journal indexed in Web of Science, Scopus or Medline); and ii) having authored an abstract in a national or international conference. We estimated crude and adjusted disparities prevalence ratios (aDPR) and 95% confidence intervals (95%CI). RESULTS: We included 2025 doctors and 2877 nurses in the analysis; 71% of doctors doctor were male, and 93% of nurses were female (p<0.001). Among doctors, 13.9% had published an article, and 8.4% presented an abstract at a conference in the last two years, while these proportions were 0.6% and 2.5% for nurses, respectively. The adjusted models showed that doctors, when compared to nurses, were approximately 27 times likely to have published a paper (aDPR = 27.86; 95% CI 10.46 to 74.19) and twice as likely to have authored a conference abstract (aDPR = 2.51; 95% CI 1.39 to 4.53). CONCLUSIONS: There are important disparities in scientific activity between doctors and nurses working in clinical settings in Peru. Disparities are more significant for article publication than for authoring in conference abstracts. We suggest public policies that promote research dissemination between health professionals, with emphasis on nurses.
