PurposeUsing science mapping analysis approach and co-word analysis, the present study explores and visualizes research fields and thematic evolution of the coronavirus. Based on this method, one can get a picture of the real content of the themes in the mentioned thematic area and identify the main minor and emerging themes.Design/methodology/approachThis study was conducted based on co-word science mapping analysis under a longitudinal study (from 1988 to 2020). The collection of documents in this study was further divided into three subperiods: 1988–1998, 1999–2009 and 2010–2020. In order to perform science mapping analysis based on co-word bibliographic networks, SciMAT was utilized as a bibliometric tool. Moreover, WoS, PubMed and Scopus bibliographic databases were used to download all records.FindingsIn this study, strategic diagrams were demonstrated for the coronavirus research for a chronological period to assess the most relevant themes. Each diagram depended on the sum of documents linked to each research topic. In the first period (1988–1998), the most centralizations were on virology and evaluation of coronavirus structure and its structural and nonstructural proteins. In the second period (1999–2009), with due attention to high population density in eastern Asia and the increasing number of people affected with the new generation of coronavirus (named severe acute respiratory syndrome virus or SARS virus), publications have been concentrated on “antiviral activity.” In the third period (2010–2020), there was a tendency to investigate clinical syndromes, and most of the publications and citations were about hot topics like “severe acute respiratory syndrome,” “coronavirus” and “respiratory tract disease.” Scientometric analysis of the field of coronavirus can be regarded as a roadmap for future research and policymaking in this important area.Originality/valueThe originality of this research can be considered in two ways. First, the strategic diagrams of coronavirus are drawn in four thematic areas including motor cluster, basic and transversal cluster, highly developed cluster and emerging and declining cluster. Second, COVID-19 is mentioned as a hot topic of research.
Background One of the requirements for scientists and researchers to enter any field of science is to have a comprehensive and accurate understanding of that discipline. Objective This study aims to draw a science map, provide structural analysis, explore the evolution, and determine new trends in research articles published in the field of breast cancer. Methods This study comprised a descriptive survey with a scientometric approach. Data were collected from MEDLINE using a search strategy based on Medical Subject Heading (MeSH) terms. This study used science mapping, which provides a visual representation and a longitudinal evolution of possible interrelations between scientific areas, documents, or authors, thus reflecting the cognitive architecture of science mapping. For this scientometric evaluation of the topic of breast cancer research, a very long period was considered for data collection. Moreover, due to the availability of numerous publications in the database, the assessment was divided into three different periods ranging from 1988 to 2020. Results A total of 12,577 records related to scientometric studies were extracted. The field of breast cancer research demonstrated three diagrams containing the most relevant themes for the three chronological periods evaluated. Each diagram was plotted based on the centrality and density linked to each research topic. The research output in the field was observed to revolve around 8 areas or themes: radiation injury, cardiovascular disease, fibroadenoma, antineoplastic agent, estrogen antagonistic, immunohistochemistry, soybean, and epitopes, each represented with different colors. Conclusions In the strategic diagrams, the themes were both well developed and important for the structuring of a research field. The first quadrant comprised motor themes of the specialty, which present strong centrality and high density (eg, corticosteroid antineoplastic age, stem cell, T-lymphocyte, protein tyrosine kinase, dietary, and phosphatidyl inositol-3-kinase). In the second quadrant of diagram, themes have well-developed internal ties but unimportant external ties, as they are of only marginal importance for the field. These themes are very specialized and peripheral (eg, DNA-binding). In the third quadrant, themes are both weakly developed and marginal. The themes in this quadrant have low density and centrality and mainly represent either emerging or declining themes (eg, ovarian neoplasm). Themes in the fourth quadrant of the strategic diagram are considered important for a research field but are not fully developed. This quadrant contains transversal and general, basic themes (eg, immunohistochemistry). Scientometric analysis of breast cancer research can be regarded as a roadmap for future research and policymaking for this important field.
Background: Ischemic stroke is one of the most frequent reasons of adult disability. Newly, few trials have represented that fluoxetine might meliorate functional recovery after stroke.
BACKGROUND Background: This study examines the relationship between obsessive-compulsive disorder (OCD) and other medical conditions and their role in the development or treatment of this disorder OBJECTIVE A co-word analysis study examines the status and intellectual structure of obsessive-compulsive disorder. Furthermore, given the multiplicity of outputs obtained from this type of study, the results can be connected to various fields related to the disease, and other related diseases can be identified through visualization. Drawing the intellectual structure in emerging and declining fields, the level of development and maturity, thematic networks and determining the thematic relationship of OCD with other diseases, the role of genetic factors, the role of complementary medicine in the treatment of this disease, etc. are among some contributions of this research project METHODS Materials and Methods: The articles published from 1975 to 2021 were retrieved by searching the related keywords in multiple databases including PubMed, Scopus, Web of Science (WoS), and Embase according to their thematic coverage and scope. Finally, after removing repeated articles and standardization, a total of 1820 papers were analyzed using R and SciMAT software. RESULTS A total of 4191 keywords plus (ID) and 3242 author keywords (DE) were reported in the journals. Moreover, these articles were published by 7482 authors, of which 111 articles were written by single authors and the collaborative coefficient (CC) was 4.36. Neuropsychopharmacology International Clinical, Psychopharmacology, and Journal of Clinical Psychopharmacology are the most influential journals publishing OCD articles. CONCLUSIONS Given the increasing prevalence of obsessive-compulsive disorders (OCDs), finding the most effective methods with the lowest prescribed dose of the drug and the most therapeutic effect is extremely important. To this end, the present study indicated that the prognosis of inherited OCD disorders, as well as the response to treatment, can be examined by analyzing the genetic sequence and finding polymorphism cases. Furthermore, complementary medicine as one of the scientific schools plays an important role in OCD diagnosis and adjuvant treatment using food and herbs and other treatment methods.
Introduction: Cardiac myxomas are the most common primary tumors of the heart with high embolic potential. Case Presentation: We present a young man with progressing stroke and atrial myxoma in an unusual site from the left upper pulmonary vein. Conclusions: Intravenous (IV) thrombolysis can be safe in patients with intracardiac myxoma and CNS embolization after good case selection. However, further studies are needed for better decision-making.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
