A study of clinical psychological nursing research hotspots in China and variation trends based on word frequency analysis and visualization analysis

Objective: To analyze clinical psychological nursing research hotspots in China and variation trends in order to provide reference points on the current state of development of clinical psychological nursing and future research hotspots.Method: Clinical psychological nursing research literature sourced from Wanfang Data for the three periods of 2007-2009, 2010-2012, and 2013-2015 were selected as the research sample. A bibliographic co-occurrence analysis system(BICOMB software) was used to perform keyword word frequency analysis and generate a keyword co-occurrence matrix. In addition, Ucinet software's Netdraw tool was used to create visualized network diagrams.Results: A total of 27890 articles were retrieved, and word frequency analysis revealed that the highestfrequency keywords consisted of anxiety, depression, the elderly, expectant women, coronary heart disease, diabetes, breast cancer, perioperative period, quality of life, and psychological intervention.Research hotspot analysis revealed that consistent hotspots comprised anxiety, depression, health education, and perioperative period; expectant women became a hotspot during 2010-2012, and quality of life and efficacy became hotspots during 2013-2015.Conclusions: In addition to the care process, clinical psychological nursing research hotspots in China have increasingly included the effectiveness of psychological nursing and impact on patient quality of life. In addition, research hotspots have been influenced by the incidence of illnesses and people's health consciousness.

Current research status and research hotspots in Chinese geriatric medicine: Data retrieved from the Chinese Journal of Geriatrics

Objective: To investigate the research hotspots and development trends of Chinese geriatric medicine by analyzing the high-frequency keywords, core authors, research institutions and their collaborations in papers published in the Chinese Journal of Geriatrics.Methods: Bibliometric methods and information visualization software(CiteSpace Ⅲ) were used to analyze the following 3 aspects: keywords, institutions and authors.Results: Overall, the number of papers published in the Chinese Journal of Geriatrics grew between 1994 and 2015. The top 3 institutions with the greatest numbers of published papers were Beijing Hospital,People's Liberation Army General Hospital and the Second Xiangya Hospital of Central South University.The authors with high productivity were Pulin Yu, Jianye Wang and Xiaoying Li. The terms "Diabetes","hypertension" and "myocardial infarction" were hotspot words that drew sustained attention in this field.Conclusions: Research on geriatric medicine is growing steadily in China. Hospitals and teaching hospitals are major contributors to publications. The collaboration of authors is more common within the same institutions or in the same regions. Clinical research is still the focus of current research. In the future, basic research should be strengthened, and collaborations between different institutions and regions should be promoted to achieve coordinated and integrated development in Chinese geriatric medicine.

Global research trends in cardiac arrest research:a visual analysis of the literature based on CiteSpace

BACKGROUND:The high morbidity,high mortality and low survival rate of cardiac arrest(CA)cause a heavy global burden.We aimed to analyze the changes in scientific output related to CA over the past two decades.METHODS:We analyzed the scientific output related to CA from 2000 to 2020 via the Web of Science.The data were analyzed using CiteSpace software.RESULTS:In total,28,312 articles relating to CA were identified in the Web of Science.The volume of scientific research output in the field of global CA research was mainly distributed in the Americas,Europe and Asia,covering a wide range.Of the 28,312 articles,the research content of the highly cited literature mainly focused on CA,mild hypothermia treatment,and prognosis of CA patients.CONCLUSION:Various scientific methods were applied to reveal scientific productivity,collaboration,and research hotspots in the CA research field.Cardiopulmonary resuscitation(CPR),extracorporeal membrane oxygenation(ECMO),survival and target temperature management are research hotspots.Future research on CA will continue to focus on its treatment and prognosis to improve the survival rate of CA patients.

Mapping the global research landscape on insulin resistance: Visualization and bibliometric analysis

BACKGROUND Insulin resistance is a risk factor for metabolic syndromes and is associated with a wide variety of metabolic illnesses,including obesity,type 2 diabetes,and cardiovascular disease.AIM To investigate and map global insulin resistance studies.METHODS A bibliometric methodology was applied to the literature retrieved from the Scopus database and Reference Citation Analysis(https://www.referencecitationanalysis.com)by using a validated search strategy.The study period was limited from 2002 to 2021.Bibliometric indicators and mapping were presented.RESULTS A total of 26808 articles on the topic of insulin resistance were included in the Scopus database.The articles included research articles(n=21918;81.76%),review articles(n=2641;9.85%),and letters(n=653;2.44%).During the study period,136 countries contributed to the research on insulin resistance.The highest number of articles was from the United States(n=7360;27.45%),followed by China(n=3713;13.85%),Japan(n=1730,6.45%),Italy(n=1545;5.54%),and the United Kingdom(n=1484;5.54%).The retrieved articles identified two main research themes:“inflammatory mechanisms in the regulation of insulin resistance”and“mechanisms linking obesity to insulin resistance”.CONCLUSION Our data show that insulin resistance has steadily gained interest from researchers,as evidenced by the number of citations and yearly publications.Publications have grown significantly in the last decade,while low-income countries with greater burdens continue to produce fewer publications in this field.This approach might assist researchers in choosing new research areas and recognizing research hotspots and frontiers.In the future,perhaps high-quality clinical evidence will be acquired.
