RESUMEN

Traumatic brain injury (TBI) is a major health concern globally, which is characterized by high morbidity and mortality rates. Since the 21st century, TBI has received increasing attention and the number of publications is growing rapidly. This study aimed to characterize the volume and quality of scholarly output on TBI and identify the most impactful literature, research trends, and hotspots from the year 2000-2022. We searched publications on TBI through the Web of Science Core Collection-Science Citation Index Expanded database which were published from 2000 to 2022. Basic information of each paper, including publication year, countries, authors, affiliations, journal, fundings, subject areas, and keywords were collected for further analysis by using Microsoft Excel, VOSviewer, and CiteSpace software. A total of 47231 TBI-related publications were identified through database retrieval. The annual number of publications on TBI has increased steadily over the past twenty years and the number in the year 2022 is sevenfold higher than that in 2000. The United States of America (USA) was the leading country in both numbers of publications and citations, which is consistent with the finding that it had the most funding agencies. Menon DK was the author with the highest influence and the University of California System was the most productive affiliation. Moreover, keywords analysis suggested that the research topics can be mainly divided into six categories: management, rehabilitation, mechanisms, concussion, neuroimaging, and neuroendocrine. This study visualized the trends and focuses of scientific research related to TBI, both quantitatively and qualitatively. The USA had a relatively high academic impact owing to its productive experts and institutions in this field. Neuroinflammation, machine learning, tranexamic acid, and extracellular vesicles are currently hot topics in the field of TBI.

RESUMEN

Background/purpose: Pemphigus and pemphigoid are systemic bullous autoimmune diseases affecting skin and/or mucosal membranes with the life-threatening nature, especially pemphigus vulgaris. The papers published by dermatologists and stomatologists preferentially represent their concerns of a mucocutaneous disease. Materials and methods: The objective of this study was to compare the scientometric characteristics of pemphigus and pemphigoid publications by dermatologists and stomatologists in the Scopus database. Results: There are 9276 and 760 papers published by dermatologists and stomatologists, respectively. The annual number of the publications by dermatologists stably raised from 218 to 526 during 2007-2022; while the number by stomatologists raised with a small amount from 18 to 51 during this period. For the most-cited top-200 papers, the total citation count is 42,766 and the h index is 148 for pemphigus publications by dermatologists; whereas the count is 14,689 and h index is 63 for publications by stomatologists. Notably, first signs of pemphigus often appear in oral mucosa, manifesting as erythema, blisters, as well as mouth ulcer, gingivitis, lichen planus-like pemphigus. Conclusion: This study firstly reports the scientometric characteristics of pemphigus publications by dermatologists and stomatologists. The scale and citations of dermatologists' publications greatly outweigh stomatologists' ones, suggesting stomatologists can learn from and more cooperate with dermatologists regarding pemphigus research.

RESUMEN

Objectives: Bibliometric analysis has emerged as a valuable method for identifying emerging areas in a given research field. Breast carcinoma has maintained a stable rank as the most common cancer affecting women worldwide. This study performed bibliometric profiling to shed light on breast cancer research conducted in KSA over the past two decades and to present the research output in the field of microRNAs (miRNA) in breast cancer in KSA. Methods: The Web of Science (WoS) and PubMed databases were selected for data retrieval, because of their high coverage, inclusion of high impact journals and easy access to high quality publications. Data retrieval was performed on January 31, 2022. Data were analyzed with Incites from WoS, PubMed and VOSviewer software version 16.1.8. Results: The most dynamic institutions, authors and active funding bodies were identified, and output on research in the field of miRNA was assessed. Bibliometric parameters including the number of publications and citation index were analyzed. A total of 3831 publications in the field were identified. A steep increase was observed in breast cancer research. The maximum number of publications was observed in 2021. King Saud University and King Faisal Specialist Hospital & Research Centre funded most of the projects and contributed the most publications. Visible progress was seen in research exploring the diagnostic and prognostic roles of mRNAs and their therapeutic potential in breast cancer. Conclusion: Breast cancer research has attracted substantial attention, as reflected by a notable increase in scientific publications over the past two decades in KSA. The bibliometric parameters revealed crucial information regarding research contributions from various institutions and authors. In the field of miRNAs, notable research investment was observed, but a significant lacuna exists. This study provides a reference that may aid oncologists, researchers and policymakers in planning future research.

RESUMEN

The purpose of this research is to analyse the evolution and trends of research into digital pedagogy in higher education through the application of bibliometric analysis and systematic review of scientific output. For the bibliometric analysis, the built-in functions of WoS were used, including Analyze results and Citation report. The VOSviewer software was employed to construct bibliometric maps. The analysis focuses on studies about digitalisation, university education and education quality, three categories that are grouped around digital pedagogies and methodologies. The sample contains 242 scientific publications, including articles (65.7%), publications published in the United States (17.7%) and publications financed by the European Commission (3.71%). Barber, W., and Lewin, C., are the authors with the greatest impact. The scientific output forms three networks: the "social network" (2000-2010), the "digitalisation network" (2011-2015) and the "network of the expansion of digital pedagogy" (2016-2023). The most-mature research (2005-2009) concerns the integration of technologies in education. The research with the greatest impact (2020-2022) looks at digital pedagogy and its implementation during the situation created by COVID-19. This research shows that digital pedagogy has come a long way over the last twenty years, but it is at the same time a topical area today. The paper opens up future paths for research such as the development of more-flexible pedagogies that can be adapted to different pedagogical scenarios.

RESUMEN

Abstract Introduction: Cambodia is a small agricultural tropical country for which only two small scientometric studies, published five years ago, were available until now. Objective: To identify, for Cambodian research, subjects, outlets, authors, institutions, citations and recommendations. Methods: The data were retrieved from the Science Citation Index Expanded (January 04, 2021) using the word "Cambodia" for the period 1972 to 2019. Results: We retrieved 3 689 documents: for the half century covered, the yearly presence of Cambodia in the index has grown strongly, to 325 articles and 6 555 authors in 2019 alone. Most documents are articles in English about health, particularly infectious and tropical diseases. Most international collaboration is done, by country, with the USA, France, and Thailand; and by institution, with Mahidol University, the Pasteur Institute and Oxford University. The most productive institutions are the Cambodian Ministry of Health and the Cambodian National Center for Parasitology. The main outlets are PLoS One, Malaria and PLoS Neglected Tropical Diseases. Cambodian articles are cited for up to 33 years, with a peak of 4.5 citations within the first two years. Those in English, or from well-funded foreign projects, have more citations in this particular index; especially if they are about malaria, hepatitis or influenza. Conclusions: The nature and impact of Cambodian science outside the SCI-EXPANDED remain unknown, but publications in that index have increased, concentrate on solving local problems, and depend heavily on international collaboration, following a well-known pattern of science in tropical countries. We suggest a funding system based on international peers who assign funds to the most productive researchers with minimal bureaucracy, so that local research is done on a greater variety of topics and with less participation of Cambodian researchers as low-level members in foreign projects.

Resumen Introducción: Camboya es un país tropical asiático pequeño y "subdesarrollado", con una economía basada en la agricultura, para el que hasta ahora solo estaban disponibles dos pequeños estudios cienciométricos, publicados hace cinco años. Objetivo: Identificar, para la investigación camboyana, qué se estudia; quién hizo la investigación; dónde y cuándo se publicó; y los factores que afectan su citación. Métodos: Usamos el Science Citation Index Expanded (4 de enero de 2021) utilizando la palabra "Camboya" y se limitaron al período 1972 a 2019. Resultados: Hallamos 3 689 documentos; durante el medio siglo cubierto, la presencia anual de Camboya en el índice ha aumentado considerablemente, con 325 artículos y 6 555 autores incorporados tan solo en 2019. La mayoría son artículos en inglés sobre salud, particularmente enfermedades infecciosas y tropicales. La mayor parte de la colaboración internacional se realiza, por país, con EE. UU., Francia y Tailandia; y por institución, con la Universidad Mahidol, el Instituto Pasteur y la Universidad de Oxford. Las instituciones más productivas son el Ministerio de Salud de Camboya y el Centro Nacional de Parasitología de Camboya. Las principales revistas son PLoS One, Malaria y PLoS Neglected Tropical Diseases. Los artículos camboyanos se citan hasta por 33 años, con un máximo de 4.5 citas en los dos primeros años. Los que son en inglés, o de proyectos dirigidos por el extranjero, tienen más citas en esta base de datos; particularmente si se trata de malaria, hepatitis o influenza. Conclusiones: La naturaleza y el impacto de la ciencia camboyana fuera del SCI-EXPANDED siguen sin conocerse, pero las publicaciones en ese índice han aumentado, se concentran en resolver problemas locales y dependen en gran medida de la colaboración internacional, siguiendo un patrón bien conocido en los países tropicales. Sugerimos un sistema de financiación basado en pares internacionales que asignen, con burocracia mínima, fondos a los investigadores más productivos, de modo que la investigación local se realice en una mayor variedad de temas y con una menor participación de investigadores camboyanos como miembros de bajo nivel en proyectos extranjeros.

RESUMEN

BACKGROUND: The number of research articles on health-related quality of life (HRQoL) has been strikingly increasing. This study aimed to explore the general trends and hotspots of HRQoL. METHODS: Based on the Web of Science database, research on HRQoL published between 2000 and 2019 were identified. A bibliometric analysis was performed based on the number of articles, citations, published journals, authors' addresses, and keywords. Descriptive analysis, visualization of geographic distribution and keyword clustering analysis were applied to the collected data. RESULTS: The annual number of articles showed growth over the past twenty years, but the annual total citations and annual citations per article were both in decreasing trends. Articles about HRQoL were more likely to be published in journals of multi-subject categories. The HRQoL research was mainly distributed across North America and Europe throughout the twenty years and ushered in a vigorous development worldwide after 2015. Cooperation strength between domestic institutions was much greater than that of international institutions. HRQoL research had six concentrated clusters: HRQoL, Depression, Obesity, Disability, Oncology, Fatigue. CONCLUSION: This study provided an overall perspective of global research trends and hotspots in HRQoL, and a potential insight for future research. HRQoL research had experienced significant increasing development during 2000-2019, especially the HRQoL measurement instruments, however, there were significant regional disparities in scientific output in HRQoL.

RESUMEN

La investigación en salud constituye la piedra angular de los sistemas de salud efectivos y eficientes; por tanto, en su evaluación es necesario estudiar la producción científica del país. El objetivo de este trabajo fue caracterizar la producción científica cubana en medicina en cuanto a su distribución temática, productividad, impacto y colaboración internacional. Para esto se realizó un estudio bibliométrico en el área temática de la Medicina y las categorías que lo componen. La base de datos utilizada fue SCImago Insitutions Rankings, a partir de datos de Scopus, en el período 2012-2017. Se hallaron indicadores bibliométricos: cuantitativos (basados en espacio de documentos); de impacto (basados en número de citas); y de la colaboración internacional (coautoría con autores de otros países). La producción científica cubana en Medicina estuvo constituida por un total de 6191 contribuciones: el 83,4 por ciento corresponde a artículos originales y el 7,40 por ciento a trabajos de revisión. Las categorías con mayor volumen de producción son: salud pública, medicina ocupacional y medioambiental (17,56 por ciento); políticas de salud (10,73 por ciento); alergia e inmunología (7,30 por ciento) y enfermedades infecciosas (6,69 por ciento). La medicina familiar aparece como debilidad en la publicación. En impacto y colaboración internacional se destacan la neurología clínica, la microbiología y las enfermedades infecciosas. Se concluye que el país hace mayor esfuerzo en las categorías de las ciencias de la Salud. Teniendo en cuenta el protagonismo de la atención primaria en el sistema nacional de salud y las principales causas de muertes, es necesario incrementar las acciones para fortalecer la publicación en la cardiología y la oncología(AU)

Health research is the cornerstone of effective, efficient health systems. Its evaluation should therefore include an assessment of the country's scientific output. The purpose of the study was to characterize the Cuban scientific output about medicine in terms of its topic distribution, productivity, impact and international collaboration. To achieve this end, a bibliometric study was conducted about medicine and the categories making it up. The database used was SCImago Institutions Rankings based on Scopus data from the period 2012-2017. The bibliometric indicators found were quantitative (based on document counts), impact (based on the number of citations) and international collaboration (co-authorships with overseas authors). Cuban scientific output about medicine consists of a total 6 191 contributions, of which 83.4 per cent are original papers and 7.40 percent are review papers. The best represented categories are public health, occupational and environmental medicine (17.56 percent), health policies (10.73 percent), allergy and immunology (7.30 percent) and infectious diseases (6.69 percent). Family medicine is scantly represented. Clinical neurology, microbiology and infectious diseases stand out in terms of impact and international collaboration. It is concluded that the country makes a greater effort in the categories of health sciences. Considering the leadership of primary health care in the national health system and the leading causes of death, it is necessary to enhance the actions aimed at strengthening publication in the fields of cardiology and oncology(AU)

RESUMEN

Background: Physiotherapy research supports the advancement of evidence-based practice and development of a highly skilled workforce. This study aims to visualize highly cited scientific output of Indian physiotherapists from 1999 to 2018. Methods: A descriptive study design was adopted to visualize highly cited scientific output of Indian physiotherapists using the Web of Science (WoS) database from 1999 to 2018. A search was carried out using the following term "((TS=(physiotherapy) OR TS=("physical rehabilitation") OR TS=("physical therapy")) AND AD=(India))Indexes=SCI-EXPANDED, SSCI, A&HCI, CPCI-S, CPCI-SSH, ESCI, CCR-EXPANDED, IC Timespan=1999-2018". Data collected were analyzed using Incites from WoS and VOSviewer software. Results:  A total of 489 articles were published between 1999 and 2018, with a peak of 103 in 2016 with 2420 citations. A decline in publication count was observed after 2016. The journal International Journal of Physiotherapy published the highest number of articles (n=35). Manipal University (n=26) was found to be the most active institution for physiotherapy research in India, as determined by producing the most articles. Indian physiotherapists published the highest number of research articles in collaboration with US authors (n=24). Conclusion: There is an increasing trend in the scientific output of Indian physiotherapists over the past two decades; however, a decline is observed after 2016. It is recommended that research collaborations across the globe are increased and scientific output should be improved, leading to a higher number of citations. Future research should explore factors influencing scientific production of Indian physiotherapists and devise appropriate strategies to attain further improvement.

RESUMEN

INTRODUCTION: Argentine science has played an important role in the study of blood pressure. However, this scientific production has not been classified. We set out (1) to analyse the contribution of scientific publications indexed in MEDLINE of authors with Argentinean academic affiliation in the field of blood pressure and hypertension in the last 50 years and, (2) determine the characteristics of the scientific journals in which they were published. METHODS: The 831 indexed MEDLINE publications by authors from Argentina were analysed quantitatively and qualitatively (period 1966-2017). RESULTS: The number of publications has increased 5.4 times in the last 20 years. Eighty percent of the publications were original manuscripts and 15% reviews. Sixty-five percent of the publications addressed clinical research, 33% basic research. The average authors per paper was 6 (89% as first author), 74% belonged to public institutions. The research was published in journals published in the United States (36%), the United Kingdom (27%), the Netherlands (12%), Spain (6%) and Argentina (4%). Eighteen percent of the publications were in journals with impact factor >3.88 (first quartile). Only 5% accessed journals with a factor ≥10. The average SJR index was 1.66. CONCLUSIONS: Argentine scientific production in MEDLINE in the field of blood pressure and hypertension showed constant growth. The vast majority is original research, directed by researchers with affiliation to public institutions. Foreign journals are accessed in the main, with acceptable quality indexes.

RESUMEN

Background and Aim: It is increasingly recognized that biomedical research has serious reproducibility issues, which could be overcome at least in part by standardized processing of biomaterials. Therefore, professional biobanks have emerged, positively influencing sample and data quality. However, quantitative data about a biobank's contribution to published results are still hard to find, although they could serve as valuable benchmark figures for the community. We therefore aimed to report usage data from the MedUni Wien Biobank facility regarding its prospective fluid cohorts. Methods: Input and access statistics and publication output were reported for the years 2010-2017. Performance dynamics were tested by correlation analyses according to Spearman. Additionally, virtual costs per sample were calculated. Results: The amount of annually collected aliquots rose significantly from 68,500 in 2010 to 151,966 in 2017 (p = 0.015), although no further increase was recorded after 2012 (p = 0.266). In the same period, the quotient of requested to stored aliquots increased from 3.5% to 6.1% (p = 0.001), as the yearly number of requested aliquots nearly quadrupled from 2401 to 9342. Likewise, the number of published research articles per year to which the MedUni Wien Biobank contributed increased from 2 (total impact factor: 8.6) in 2010 to 16 (total impact factor: 69.0) in 2017, resulting in a total of 69 identified publications. Currently, the biobank operates at 15- to 20-fold overproduction, leading to virtual costs per accessed sample of ∼€20. Conclusion: The reported usage data might serve as a benchmark for other hospital-integrated biobanks, and implies that academic biobanks are able to produce considerable scientific impact at comparable moderate costs.

RESUMEN

Resumen Guatemala, con 16 millones de habitantes, es la mayor economía de Centroamérica y, por tanto, podría tener la mayor producción científica de la región. Para evaluar su productividad y su impacto, en junio 2017 analizamos los 3 380 artículos de Guatemala incluidos en el SCI-ampliado. La mayoría de los documentos de Guatemala son artículos en inglés, tratan problemas de nutrición y salud y tienen una media de 7.4 autores por artículo. También en esta base de datos en particular, los artículos siguen siendo citados durante 40 años, y se citan más los artículos en inglés (dos veces más que en español), las revisiones (media: 24 citas por artículo de revisión) y los estudios resultantes de colaboración internacional, dominada por Estados Unidos y México. Las instituciones más productivas son el Centro de Estudios de Deterioro Sensorial CESSIAM, las universidades de San Carlos y del Valle, y el Instituto Centroamericano de Nutrición INCAP (pero el último ha disminuido la productividad en los últimos años). Los investigadores más productivos son N.W. Solomons, R. Bressani, L.G. Elías, C. Rolz y A. Cáceres. Guatemala representa un caso particular en Centroamérica, porque su investigación de alta calidad depende en gran medida de investigadores particulares, no tanto de las instituciones, y porque la producción total está muy por debajo de las expectativas para un país con esa población. La productividad y el impacto de la ciencia guatemalteca en las 18 revistas publicadas en el país, y en otras revistas que tampoco están cubiertas en el SCI-ampliado, siguen siendo desconocidos. Sin embargo, la tendencia histórica es positiva, con un claro crecimiento de la colaboración internacional, la productividad y el impacto.

Abstract Guatemala, with 16 million inhabitants, is the largest economy of Central America and should have the largest scientific output of the region. To assess its productivity and impact, we analyzed the 3380 Guatemala articles included in the SCI-expanded in June, 2017. Most Guatemala documents are articles in English, deal with nutrition and health problems, and have a mean of 7.4 authors per article. Also in this particular database, citation lifespan is 40 years, and citations are higher for articles in English (twice more than those in Spanish), for reviews (mean 24 citations per review) and for studies resulting from international collaboration, which is done mostly with the USA and Mexico. The most productive institutions are the Center for Studies of Sensory Impairment (CESSIAM), the universities of San Carlos and El Valle, and the Central American Nutrition Institute (INCAP, but it has decreased productivity in recent years). The most productive researchers are N.W. Solomons, R. Bressani, L.G. Elías, C. Rolz and A. Cáceres. Guatemala represents a particular case in Central America because its high quality research is dependent on particular researchers rather than on institutions, and because the total output is well under the expectation. The productivity and citation of Guatemalan science in the 18 journals published in the country, and in other journals which are also not covered in the SCI-expanded, remain unknown. Nevertheless, the historical trend is positive, with a clear growth of international collaboration, productivity and citation. Rev. Biol. Trop. 66(1): 312-320. Epub 2018 March 01.

RESUMEN

BACKGROUND: In a clinical science-based profession such as physiotherapy, research is mandatory to update knowledge and to provide cost-effective, high quality treatments. This study aimed to provide point prevalence of Italian physiotherapists who are academics, holding a PhD degree, or being authors of scientific papers. The scientific journal productivity of physiotherapists was also thoroughly analyzed. METHODS: A descriptive cross-sectional study was carried out on all Italian physiotherapists. Academics, postdoctoral research fellows, and PhD graduates were identified by searching the Italian Ministry of Education, University and Research (MIUR), Italian Society of Physiotherapy, and university websites. Then, authors of articles indexed in Scopus were searched. The following data were extracted: type of affiliation, authorship order, H-index, number of publications and citations, name of journals, year of publication, and journal's Impact Factor. RESULTS: The prevalence of academics, physiotherapists holding a PhD, or being author was 0.01%, 0.05%, and 0.56%, respectively. We identified 1083 papers co-authored by Italian physiotherapists, and their number has progressively increased over the years (p < 0.001). There was a significant difference between researchers and clinicians in both publication productivity (p < 0.01), citations (p < 0.01), and H-Index (p = 0.05). Articles were published in 359 different journals, receiving a total of 13,373 citations. CONCLUSIONS: Despite the low prevalence of faculty members and the reduced availability of PhD programs in Italy (forcing some students to study abroad), the quantity and quality of journal productivity is growing fast, and an increasing number of physiotherapists are involved in research activities.

RESUMEN

ABSTRACT This article presents an analysis of Brazilian research on High Energy Physics (HEP) indexed by Web of Science (WoS) from 1983 to 2013. Scientometric indicators for output, collaboration and impact were used to characterize the field under study. The results show that the Brazilian articles account for 3% of total HEP research worldwide and that the sharp rise in the scientific activity between 2009 and 2013 may have resulted from the consolidation of graduate programs, the increase of the funding and of the international collaboration as well as the implementation of the Rede Nacional de Física de Altas Energias (RENAFAE) in 2008. Our results also indicate that the collaboration patterns in terms of the authors, the institutions and the countries confirm the presence of Brazil in multinational Big Science experiments, which may also explain the prevalence of foreign citing documents (all types), emphasizing the international prestige and visibility of the output of Brazilian scientists. We concluded that the scientometric indicators suggested scientific maturity in the Brazilian HEP community due to its long history of experimental research.
