Mapping theme trends and recognizing hot spots in viral pneumonia: a bibliometric analysis of global research.

BACKGROUND: The challenges that viral pneumonia poses to the global public health system remain daunting. In this study, an analysis of publications on viral pneumonia over the past two decades was conducted. Through this work, we hope to provide inspiration for future research on viral pneumonia. METHODS: We extracted all of the English publications relevant to viral pneumonia published during 1999-2019 from Web of Science. GraphPad Prism, CiteSpace, and VOSviewer were used to collect and analyze the publication trends in related fields. RESULTS: We identified 2,006 publications with 62,155 citations as of February 16, 2021. The United States accounted for the largest number of publications (34.2%), with the highest number of citations (27,616) and the highest h-index (78). China ranked second in the number of publications. Ctr Dis Control & Prevent proved to be the center of research cooperation. Clinical Infectious Diseases included the most papers published relating to the topic of viral pneumonia. Chan KH published the most papers in this field (25), while an article from Fouchier RAM presented the highest citation frequency (1,275). CONCLUSIONS: According to the bibliometric analysis database and related software results, the United States dominates the field of viral pneumonia research. The key term extracted by VOSviewer has shifted to "Diagnosis and management", indicating a new trend for viral pneumonia research.

Mapping theme trends and recognizing research hot spots in the use of ultrasound in orthopaedics: a bibliometric analysis of global research.

BACKGROUND: In the past decade, ultrasound has been increasingly used in the field of orthopaedics. The purpose of this study is to inspire future research in this field by analyzing the publications relating to ultrasound research in orthopaedics. METHODS: All relevant articles published between 2009 and 2020 were retrieved from Web of Science. Statistical Package for Social Science and GraphPad Prism 8 software were used to generate and analyse diagrams. VOSviewer software and CiteSpace were employed to visualize the research trends based on co-occurring keywords. Finally, we obtained information about relevant clinical randomized controlled trials (http://clinicaltrials.gov.com/). RESULTS: The United States had the most publications in this field and the most citations and the highest H-index. Furthermore, Skeletal Radiology published the most papers related to the use of ultrasound in orthopaedics, Ozcakar L published the most papers, and a study by Kwon, YM had the highest citation frequency. The keywords "MRI", "complication", "female" and "male" were identified as being indicative of emerging topics. CONCLUSIONS: While the contribution of United States to publications in this field has been substantial, the future contributions of China cannot be ignored. Moreover, it is hypothesized that diagnostic and epidemiological aspects may become hotspots.

Mapping Trends and Hotspots Regarding Clinical Research on COVID-19: A Bibliometric Analysis of Global Research.

Purpose: The coronavirus disease 2019 (COVID-19) outbreak, which began in December 2019, has not been completely controlled; therefore, COVID-19 has received much attention from countries around the world. Many related clinical studies, such as clinical trials, have been published, but to the knowledge of the authors, there has been no bibliometric analysis of these publications focusing on clinical research studies on COVID-19. Methods: Global publications on COVID-19 from January 2020 to December 2020 were extracted from the Web of Science (WOS) collection database. The VOSviewer software and CiteSpace were employed to perform a bibliometric study. In addition, we obtained information on relevant clinical trials from the website http://clinicaltrials.gov. Results: China published most of the articles in this field and had the highest number of citations and H-index. The Journal of Medical Virology published most of the articles related to COVID-19. In terms of institutions, Huazhong University of Science and Technology had the most publications, and Wang, JW received the highest number of citations. Conclusion: The diagnosis, prevention, and prognosis of COVID-19 are still the focus of attention at present. The overall analysis of the disease were identified as the emerging topics from the perspectives of epidemiology and statistics. However, finding an effective treatment remains the focus of clinical trials.

Research progress of heat stroke during 1989-2019: a bibliometric analysis.

BACKGROUND: Heat stroke (HS) is an acute physical disorder that is associated with a high risk of organ dysfunction and even death. HS patients are usually treated symptomatically and conservatively; however, there remains a lack of specific and effective drugs in clinical practice. An analysis of publication contributions from institutions, journals and authors in different countries/regions was used to study research progress and trends regarding HS. METHODS: We extracted all relevant publications on HS between 1989 and 2019 from Web of Science. Using the Statistical Package for Social Science (SPSS, version 24) and the software GraphPad Prism 8, graphs were generated and statistical analyses were performed, while VOSviewer software was employed to visualize the research trends in HS from the perspectives of co-occurring keywords. RESULTS: As of April 14, 2020, we identified 1443 publications with a citation frequency of 5216. The United States accounted for the largest number of publications (36.2%) and the highest number of citations (14,410), as well as the highest H-index at 74. Although the sum of publications from China ranked second, there was a contradiction between the quantity and quality of publications. Furthermore, Medicine & Science in Sports & Exercise published the most papers related to HS, with Lin MT publishing the most papers in this field (112), while the review by Knochel JP received the highest citation frequency at 969. The keyword heat-stress appeared most recently, with an average appearing year of 2015.5. In the clinical research cluster, exertional heat-stroke was determined to be the hotspot, while ambient-temperature and heat waves were the new trends in the epidemiological research cluster. CONCLUSIONS: Corresponding to this important field, while the contributions of the publications from the United States were significant, the mismatch between the quantity and quality of publications from China must be examined. Moreover, it is hypothesized that clinical and epidemiological studies may become hotspots in the near future.

Analysis on the output of pharmaceutical papers and highly cited papers in Double First-rate universities / 药学实践杂志

Objective To understand the current situation of pharmaceutical research development in China and provide a constructive thinking for universities to serve the national innovation strategy through the statistical analysis of pharmaceutical papers and highly cited papers from Double First-rate universities. Methods CNKI, Wanfang, VIP and Chinese Biomedical Literature Database were searched for Chinese publications, and Scopus database was searched for English publications. Duplicates and non-research literatures were excluded. Excel 2016 software was used for statistical data analysis. Results By comparing the data from 2017 to 2019 with that from 2014 to 2016, it was found that the number of papers in Q1 area from international journals and Q2 area from domestic journals increased significantly. The popularity of publishing papers in international journals by university authors was increasing. The number of publications in domestic journals slightly decreased. From 2014 to 2020, 850 papers were published in domestic journals, among which 223 papers were highly cited, with a total cited times of 2 410 and an average cited times per publication of 10.81. Conclusion In spite of the government’s encouragement to publish the scientific and technological achievements in domestic journals, no such trend was formed from our analysis. Therefore, it is necessary to further build the corresponding academic ecology and enhance the international influence of domestic journals. The science and technology circles and technology publication circles in China should be deeply integrated to promote mutual development.

Predictors of Citation Rate in Psychology: Inconclusive Influence of Effect and Sample Size.

In the present article, we investigate predictors of how often a scientific article is cited. Specifically, we focus on the influence of two often neglected predictors of citation rate: effect size and sample size, using samples from two psychological topical areas. Both can be considered as indicators of the importance of an article and post hoc (or observed) statistical power, and should, especially in applied fields, predict citation rates. In Study 1, effect size did not have an influence on citation rates across a topical area, both with and without controlling for numerous variables that have been previously linked to citation rates. In contrast, sample size predicted citation rates, but only while controlling for other variables. In Study 2, sample and partly effect sizes predicted citation rates, indicating that the relations vary even between scientific topical areas. Statistically significant results had more citations in Study 2 but not in Study 1. The results indicate that the importance (or power) of scientific findings may not be as strongly related to citation rate as is generally assumed.

Global scientific collaboration in COPD research.

PURPOSE: This study aimed to investigate the multiple collaboration types, quantitatively evaluate the publication trends and review the performance of institutions or countries (regions) across the world in COPD research. MATERIALS AND METHODS: Scientometric methods and social network analysis were used to survey the development of publication trends and understand current collaboration in the field of COPD research based on the Web of Science publications during the past 18 years. RESULTS: The number of publications developed through different collaboration types has increased. Growth trends indicate that the percentage of papers authored through multinational and domestic multi-institutional collaboration (DMIC) have also increased. However, the percentage of intra-institutional collaboration and single-authored (SA) studies has reduced. The papers that produced the highest academic impact result from international collaboration. The second highest academic impact papers are produced by DMIC. Out of the three, the papers that are produced by SA studies have the least amount of impact upon the scientific community. A handful of internationally renowned institutions not only take the leading role in the development of the research within their country (region) but also play a crucial role in international research collaboration in COPD. Both the amount of papers produced and the amount of cooperation that occurs in each study are disproportionally distributed between high-income countries (regions) and low-income countries (regions). Growing attention has been generated toward research on COPD from more and more different academic domains. CONCLUSION: Despite the rapid development in COPD research, collaboration in the field of COPD research still has room to grow, especially between different institutions or countries (regions), which would promote the progress of global COPD research.

Allocation methods of coauthor credit in collaboration of scientific research / 中华医学图书情报杂志

The rationality of hormonal calculating method for the precedence of signed authors and the total num-ber of coauthors was elaborated according to the analysis of different allocation methods for the credit weight of coau-thors. It was proposed that the credit weight calculating method of co-first authors, corresponding author and co-corresponding authors should be used as a supplement of hormonal calculating method, and the published papers and their citation frequency should be weighted in order to provide the ideas for revising the present scientific re-search evaluation methods.

Bibliometric Analysis of Metabolomics / 中国药房

OBJECTIVE:To investigate the present situation of domestic and foreign metabolomics study,and to preliminarily discuss research hotspots and development rules. METHODS:By using bibliometric methods and GoPubMed literature analysis tool,usingMetabolomicsas subject,all literatures were retrieved from PubMed database up to Jul. 31,2016. Those literatures were ranked and analyzed in respects of publication amount,countries and cities,journal sources,research topics,core authors and authors collaborative networks. UsingMetabolomicsMetabonomicsas subjects,all literatures were retrieved from Web of Science database up to Aug. 1,2016. The literatures with high citation frequency were analyzed during 2007-2016 by using the sort-ing function of citation frequency. RESULTS:A total of 15449 domestic and foreign metabolomics literatures were retrieved. The researchers of 2189 literatures came from China,and the amount of published literatures showed a rising trend. 15449 literatures were distributed in 129 countries and regions;10 countries,such as the United States,China,Britain and Germany,were the core countries,and the total number of literatures issued was 12847(83.16%). The United States held the largest share of world publi-cations(4288 literatures,27.76%),and the following was China in order(2189 literatures,14.17%). The city with the largest amount of publications was London(467 literatures),followed by Shanghai,Beijing. A total of 2168 periodicals were involved, and there were 7.1 published literatures averagely. All of the top 20 periodicals were from the United States and European countries (4377 literatures,28.33%). The first 3 subjects with the highest frequency of occurrence were metabolomics,metabolome and me-tabolism;related researches mainly focused on metabolic processes,metabolic networks and pathways,biological markers,pro-teome and genome;main research methods included spectrum analysis and magnetic resonance spectroscopy. Main 6 groups of au-thors were involved,mainly Nicholoson JK,Holmes E,Lindon J and other researchers. None of Chinese researchers had been found among the core authors and author groups. The literatures with high citation frequency mainly focused on the association of metabolism with disease,metabolomics database,metabolomics research methods and biological markers related to disease predic-tion. CONCLUSIONS:Metabolomics has aroused worldwide interest among researchers,and metabolic pathways and biological markers are the focuses in this field. Our researchers have published a large amount of literatures on metabolomics,but there are not high quality periodical carrier or enough cooperation between researchers. It is suggested to enhance the cooperation between various research institutions or grasp the frontier and hotspots of the research in this field so as to push forward the development di-versification and depth of metabolomics research in China.

Every scientist is a memory researcher: Suggestions for making research more memorable.

Independent of the actual results, some scientific articles are more memorable than others. As anyone who has written an article collaboratively knows, there are numerous ways a manuscript can be written to convey the same general ideas. To aid with this, many scientific writing books and editorials provide advice, often anecdotal, on how to make articles more memorable. Here I ground these suggestions with empirical support from memory research. Specifically, I suggest that researchers consider how to emphasize their work's novelty, strive to describe their work using concrete, easy-to-understand terms, and use caution when attempting to evoke an emotional response in the reader. I also discuss considerations in title selections and conference presentations.
