Objective To investigate the current status of esophageal cancer surgery-related researches using bibliometric methodologies and identify the trend and hotspots. Methods The Chinese and English literature was collected from Web of Science and CNKI from inception of each database to April 1, 2022. VOSviewer 1.6.18 and CiteSpace 6.1 were applied to cluster the authors, institutions, and keywords. For social network and time series analysis, Excel, GraphPad, and R 4.0.3 were used to visualize the literature on esophageal cancer surgery. Results Finally, 19 566 English literature and 19 872 Chinese literature was included. The results demonstrated that the annual publishing of both Chinese and English literature increased over time, with English literature increasing rapidly and Chinese literature maintaining an average number of above 1 000 per year from 2011 to 2019. Researches were predominantly centered in Europe, the United States, Japan, South Korea, and China. China's researches in the field of surgical treatment in esophageal cancer lacked international collaboration, which began later than East Asian countries such as Japan and South Korea and had less influence. From the keyword perspective, previous researches on surgical treatment of esophageal cancer mostly focused on surgical techniques, complications, and comprehensive perioperative therapy. Both Chinese and English literature showed that the prevalence of keywords such as minimally invasive surgery, comprehensive treatment, and clinical trials increased dramatically during the recent years, indicating that these fields may represent the future directions and research trends. Conclusion Compared to East Asia countries, such as Japan and South Korea, Chinese esophageal cancer surgery-related researches are relatively lacking. The research direction and field are similar to those in developed countries such as the United States and Europe. Future attention may be focused on minimally invasive treatment, comprehensive treatment, and clinical trials associated with surgical treatment of esophageal cancer.
Objective To review the research hotspots and cutting-edge dynamics in the field of hospital operations management, providing references for relevant research in our country. Methods Using CiteSpace 6.1.R6 software, we conducted a visual analysis of English literature in the field of hospital operations management collected from the Web of Science database Core Collection from the establishment of the database to December 31st 2022. Result A total of 808 articles were included, with the first article in the field of hospital operations management published in 1980 since the establishment of the Web of Science database. Over the 42-year period, annual publications had shown an increasing trend. Research outcomes were concentrated in institutions and researchers from Europe and the United States, but academic collaboration among institutions and authors was not particularly close. The hotspots in related fields mainly focused on aspects of care quality, management, and performance. Conclusions Studies on hospital operations management in China are in the early stage, and the international influence of research outcomes needs to be further strengthened. The research frontier has shifted from healthcare quality and safety to internal financial performance, human resource management, and resource allocation. Research on the application of technological methods in hospital operations management will continue to emerge.

Objective To conduct a systematic and comprehensive bibliometric analysis related to medical imaging in coronavirus disease 2019 (COVID-19) published by Chinese authors, and indicate the current status and guidance for coping with the challenges brought by long COVID. Methods Literature records pertaining to COVID-19 imaging were retrieved from the Web of Science (WOS) and Chinese Science Citation Database (CSCD) with a date range of January 1st, 2020 to December 31st, 2022. CiteSpace was used to analyze the popular topics and generate a visual map to further refine research trends. Results The search enrolled 2229 publications (1771 publications from WOS and 458 from CSCD). The monthly volume of publications showed a significant increase followed by a gradual decline, and then maintained a stable level. Clustering analysis of keywords and co-citations revealed that the research hotspots in COVID-19 imaging were clinical features, imaging differential diagnosis, and the application of artificial intelligence. Keyword burst analysis showed that “deep learning” was the most intensive keyword, while “attention mechanism” had the longest burst duration. Conclusions In recent years, the research in the field of COVID-19 imaging has made steady progress. Artificial intelligence has received the most attention. Clinical features, imaging features and artificial intelligence assisted diagnosis are the top of most concerns. The future focus of COVID-19 imaging research may be on improving algorithm models to expand the application of artificial intelligence in disease diagnosis, treatment, and management.
Objective To discover the similarities and differences between CBM and MEDLINE databases in the field of post-earthquake health issue research characteristics in order to provide references and aids to the scientific research administration, professional education and training, research subjects selection and project finance support. Methods CBM and MEDLINE databases (from January 1987 to December 2009) were systematically searched to obtain literature about post-earthquake health issues. Those studies were classified and compared by the characteristics of research objects, health issues, research periods, and types of study design. Results A total of 701 literature from CBM and 387 from MEDLINE were included. MEDLINE database provided more studies focusing on victims of natural calamities with specific age description than CBM (Plt;0.05). Research peak of CBM database centralized in the period of three months after earthquake (n=645, 92%), while MEDLINE was three years after the earthquake (n=191, 87.2%). Studies from both databases similarly focused on physical trauma and psychiatric/psychological issues (two types of health issues in total: CBM: n=727, 86.1%; MEDLINE: n=358, 83.4%). Investigations from CBM were primarily designed for retrospective and descriptive research (n=439, 62.6%), cross-sectional investigations (n=146, 20.8%) and case report (n=86, 12.3%) while MEDLINE focalized on cross-sectional investigations (n=177, 45.7%) and retrospective and descriptive research (n=146, 37.7%). Conclusion Compared to MEDLINE, studies from CBM database are relatively weak in the post-earthquake health issues of population with specific age characters, long-term health issues, levels of evidence and types of research design. The possible reasons are insufficient attention to the post-earthquake health issues, inadequate preparation for the research or limited knowledge about research methods.
