However, issues such as use of doping, doping agents, and using methods attract the attention of researchers. The research aims to analyze all scientific publications between 1980 and 2021 and to make a holistic analysis on doping using data obtained within the scope of the study, information graphics and explanatory bibliometric networks were created. This research is a kind of qualitative research method conducted to determine the researches between the Olympics and doping studies. According to the results, most used keywords were found to be "doping", "Olympic Games" and "doping control". There are a total of 96 journals evaluated within the scope of our study. “British Journal of Sports Medicine”, “Deutsche Zeitschrift Für Sportmedizin” and “International Journal of The History of Sport” are most cited journals. Top publishing institutes are “University of Western Australia”, “German Sport University Cologne” and “National and Kapodistrian University of Athens”. Finally, and in turn, top broadcasting countries are USA, United Kingdom, Germany, Australia, and Switzerland. According to the results of the research, most of the research on doping focuses on chemical analysis of substances used as doping. It may be useful to conduct research on the physical, social and moral reasons and possible legal consequences of doping use and its effect on sports.

Exploring Match Space: How Medical School and Specialty Characteristics Affect Residency Match Geography in the United States

To explore how school and specialty characteristics impact the geographic match location of U.S. senior medical students. The authors collected student match data between 2018 and 2020 from U.S. MD-granting medical schools and calculated the distance between students' medical schools and residency training programs. They use the term "match space" to describe this distance. Match space was codified on a 5-point ordinal scale by where the student matched: 1 = home institution, 2 = home state, 3 = an adjacent state, 4 = the same or adjacent U.S. Census division (and not adjacent state), and 5 = skipped at least one U.S. Census division. Ordinal logistic regression correlated school and specialty characteristics with match space. During the study period, 26,102 medical students, representing 66 medical schools from 28 states, matched in 23 specialties. Fifty-nine percent of students were from public institutions, and 27% of schools ranked in the top 40 of National Institutes of Health (NIH) research funding. The match space was higher for students graduating from private institutions (odds ratio [OR] 1.14; 95% confidence interval [CI], 1.06 to 1.22) and matching into more competitive specialties (OR 1.07; 95% CI, 1 to 1.14). The match space was lower for students graduating from top NIH-funded institutions (OR 0.89; 95% CI, 0.85 to 0.94) and from schools with a higher percentage of in-state matriculants (OR 0.75; 95% CI, 0.72 to 0.77). School characteristics such as region, public/private designation, NIH funding, and percentage of in-state students were associated with residency match geography. Matching into more competitive specialties also showed a marginal increase in match distance. These findings suggest that a student's choice of specialty and medical school may impact subsequent geographic placement for residency training, which should be considered by students and residency programs alike.

Edible insects: A bibliometric analysis and current trends of published studies (1953–2021)

Edible insects have huge potential as an important alternative food and feed, and research in this area has developed considerably over the past few decades. In this study, a bibliometric analysis was conducted for the first time to provide a quantitative and visualization analysis of the trends in the edible insect research landscape. Documents on 'edible insects' OR 'insects as food' OR 'entomophagy' published from 1953 until 2021 were retrieved from the Scopus database and analyzed in terms of publication output, active journals and countries, leading authors, and institutes, and main keywords. The VOSviewer program was used to visualize trends in the bibliographic information. A total of 1376 documents were published in this time duration on the topic. Meyer-Rochow, Van Huis; Journal of Insect as Food and Feed; and Wageningen University and Research were respectively the top publishing authors, leading journals, and research institutes. Keywords analysis and categorization of studies highlighted 'food security', 'food neophobia', 'functional properties', 'food processing', and 'sustainability' as some of the main areas of interest and research trends, and that research on 'edible insects' is highly multidisciplinary. We have surmised potential 'hotspot' areas of developing research and key players and activities that can drive the research and development of edible insects for use as food. International collaborations to bridge knowledge and habit of entomophagy in many developing countries with the skills and facilities of developed countries could lead to accelerated utilization and commercialization of this food source.Graphical abstract

Knowledge Mapping of Multicriteria Decision Analysis in Healthcare: A Bibliometric Analysis.

ObjectiveMulticriteria decision analysis (MCDA) is a useful tool in complex decision-making situations, and has been used in medical fields to evaluate treatment options and drug selection. This study aims to provide valuable insights into MCDA in healthcare through examining the research focus of existing studies, major fields, major applications, most productive authors and countries, and most common journals in the domain.MethodsA bibliometric analysis was conducted on the publication related to MCDA in healthcare from the Web of Science Core Collection (WoSCC) database on 14 July 2021. Three bibliometric software (VOSviewer, R-bibliometrix, and CiteSpace) were used to conduct the analysis including years, countries, institutes, authors, journals, co-citation references, and keywords.ResultsA total of 410 publications were identified with an average yearly growth rate of 32% (1999–2021), from 196 academic journals with 23,637 co-citation references by 871 institutions from 70 countries/regions. The United States was the most productive country (n = 80). Universiti Pendidikan Sultan Idris (n = 16), Université de Montréal (n = 13), and Syreon Research Institute (n = 12) were the top productive institutions. A A Zaidan, Mireille Goetghebeur and Zoltan Kalo were the biggest nodes in every cluster of authors' networks. The top journals in terms of the number of articles (n = 17) and citations (n = 1,673) were Value in Health and Journal of Medical Systems, respectively. The extant literature has focused on four aspects, including the analytic hierarchy process (AHP), decision-making, health technology assessment, and healthcare waste management. COVID-19 and fuzzy TOPSIS received careful attention from MCDA applications recently. MCDA in big data, telemedicine, TOPSIS, and fuzzy AHP is well-developed and an important theme, which may be the trend in future research.ConclusionThis study uncovers a holistic picture of the performance of MCDA-related literature published in healthcare. MCDA has a broad application on different topics and would be helpful for practitioners, researchers, and decision-makers working in healthcare to advance the wheel of medical complex decision-making. It can be argued that the door is still open for improving the role of MCDA in healthcare, whether in its methodology (e.g., fuzzy TOPSIS) or application (e.g., telemedicine).

Patient Safety and Legal Regulations: A Total-Scale Analysis of the Scientific Literature.

The aim of the study was to quantitatively analyze the scientific literature landscape covering legal regulations of patient safety. This retrospective bibliometric analysis queried Web of Science database to identify relevant publications. The identified scientific literature was quantitatively evaluated to reveal prevailing study themes, contributing journals, countries, institutions, and authors, as well as citation patterns. The identified 1295 publications had a mean of 13.8 citations per publication and an h-index of 57. Approximately 78.8% of them were published since 2010, with the United States being the top contributor and having the greatest publication growth. A total of 79.2% (n = 1025) of the publications were original articles, and 12.5% (n = 162) were reviews. The top authors (by number of publications published on the topic) were based in the United States and Spain and formed 3 collaboration clusters. The top institutions by number of published articles were mainly based in the United States and United Kingdom, with Harvard University being on top. Internal medicine, surgery, and nursing were the most recurring clinical disciplines. Among 4 distinct approaches to improve patient safety, reforms of the liability system (n = 91) were most frequently covered, followed by new forms of regulation (n = 73), increasing transparency (n = 67), and financial incentives (n = 38). Approximately 78.8% of the publications on patient safety and its legal implications were published since 2010, and the United States was the top contributor. Approximately 79.2% of the publications were original articles, whereas 12.5% were reviews. Healthcare sciences services was the most recurring journal category, with internal medicine, surgery, and nursing being the most recurring clinical disciplines. Key relevant laws around the globe were identified from the literature set, with some examples highlighted from the United States, Germany, Italy, France, Sweden, Poland, and Indonesia. Our findings highlight the evolving nature and the diversity of legislative regulations at international scale and underline the importance of healthcare workers to be aware of the development and latest advancement in this field and to understand that different requirements are established in different jurisdictions so as to safeguard the necessary standards of patient safety.

Research Trends around Exercise Rehabilitation among Cancer Patients: A Bibliometrics and Visualized Knowledge Graph Analysis.

This study analyzed the research hotspots and frontiers of exercise rehabilitation among cancer patients via CiteSpace. Relevant literature published in the core collection of the Web of Science (WoS) database from January 1, 2000, to February 6, 2022, was searched. Further, we used CiteSpace5.8R1 to generate a network map and identified top authors, institutions, countries, keywords, and research trends. A total of 2706 related literature were retrieved. The most prolific writer was found to be Kathryn H Schmitz (21 articles). The University of Toronto (64 articles) was found to be the leading institution, with the United States being the leading country. Further, “rehabilitation,” “exercise,” “quality of life,” “cancer,” and “physical activity” were the top 5 keywords based on frequency; next, “disability,” “survival,” “fatigue,” “cancer,” and “rehabilitation” were the top 5 keywords based on centrality. The keyword “fatigue” was ranked at the top of the most cited list. Finally, “rehabilitation medicine,” “activities of daily living,” “lung neoplasm,” “implementation,” “hospice,” “exercise oncology,” “mental health,” “telemedicine,” and “multidisciplinary” are potential topics for future research. Our results show that the research hotspots have changed from “quality of life,” “survival,” “rehabilitation,” “exercise,” “cancer,” “physical therapy,” “fatigue,” and “breast cancer” to “exercise oncology,” “COVID-19,” “rehabilitation medicine,” “inpatient rehabilitation,” “implementation,” “telemedicine,” “lung neoplasm,” “telehealth,” “multidisciplinary,” “psycho-oncology,” “hospice,” “adapted physical activity,” “cancer-related symptom,” “cognitive function,” and “behavior maintenance.” Future research should explore the recommended dosage and intensity of exercise in cancer patients. Further, following promotion of the concept of multidisciplinary cooperation and the rapid development of Internet medical care, a large amount of patient data has been accumulated; thus, how to effectively use this data to generate results of high clinical value is a question for future researchers.

0355 Which hospitals are the quietest at night? It’s not The US News Top 20 Institutions

Abstract Introduction The Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey distributed by The Center for Medicare and Medicaid (CMS) services measures patient perceptions of hospital experience and impacts annual CMS reimbursement. This study focuses on the “Quiet at Night” variable, to identify the top box institutions and identify the key characteristics that enable their success. Methods Using the Linear Mean Scores and the Star Ratings’ inherent clustering algorithm and RStudio™, the top box scorers amongst the 5 Star Rated hospitals were isolated and grouped together as CMS Top Rated “Quiet at Night” Hospitals. These Star Ratings and the key characteristics of these institutions were compiled and compared to the US News Honor Roll Hospitals (2019-2020) to ascertain trends and determine the predictive value of the HCAHPS “Quiet at Night”' hospitals' characteristics. Results The mean Star Rating for CMS Top Rated “Quiet at Night” Hospitals was 5.00 compared to that of the US News Honor Roll Hospitals which was 2.67. An unpaired t-test of this data found a two-tailed P value of less than 0.0001, which is considered statistically significant under all conventional significance levels (Table 1). In comparing the key characteristics for these two lists documented by the American Hospital Directory a stark difference emerged between these groups with those that scored well on the “Quiet at Night'' question identifying as predominantly privately controlled, specialized, surgical facilities with very few total hospital beds. Conclusion This study was the first of its kind to critically analyze hospitals that score well on the CMS “Quiet at Night” and compare them to the US News Honor Roll Best Hospitals. With the knowledge that these scores impact CMS reimbursement, it is important to determine the cultural and organizational shifts that enable hospitals to be top performers on the “Quiet at Night” metric. A greater understanding of how top CMS hospitals so efficiently provide care in a sleep protective way may help inform larger institutions about Best Practices. Support (If Any)

Gender Differences of Endowed Professorship in Obstetrics and Gynecology Departments at Top Academic Institutions [A72

INTRODUCTION: Barriers to gender equality permeate academic medicine. A recent study demonstrated that women are less likely to hold endowed professorships in internal medicine from top schools. Given the resources and prestige that accompany endowed professorships, this designation can gauge diversity within medicine’s leaders. We assessed endowed professorships within obstetrics and gynecology departments at leading American medical schools. METHODS: Obstetrics and gynecology faculty lists were obtained from the top 25 academic institutions, as determined by 2020 National Institutes of Health (NIH) ranking. Data on faculty position, endowed professorship/chair, gender, graduate degrees held, graduation year, publication and citation numbers, H-index, and NIH funding as a principal investigator were collected from departments or publicly available sources (e.g., institutional websites, Scopus [Elsevier], NIH Reporter). Multivariable regression models were constructed to explain holding endowed professorships. RESULTS: Of the 680 total professors, 400 (58.8%) were women and 280 (41.2%) were men. From these groups, 64 (49.2%) women and 66 (50.8%) men held endowed professorships. On multivariable analysis, there were no significant differences between men and women in attainment of endowed professorships (P=.83). Faculty with non-MD doctorates (P=.006) and rank of associate professor (P<.001) were less likely to have endowed chairs. Those in the top two quartiles of number of publications (P<.001) and in the highest funding quartile (P=.004) were more likely to have endowed professorships. Endowed professorships were not significantly related to decade of graduation (P=.86). CONCLUSION: Despite previous findings of gender inequity among endowed professorships from internal medicine departments, obstetrics and gynecology departments at leading institutions show no significant role of gender at the level of endowed chairs.

Intellectual Structure and Emerging Trends of White Matter Hyperintensity Studies: A Bibliometric Analysis From 2012 to 2021.

White matter hyperintensities (WMHs), which have a significant effect on human health, have received increasing attention since their number of publications has increased in the past 10 years. We aimed to explore the intellectual structure, hotspots, and emerging trends of publications on WMHs using bibliometric analysis from 2012 to 2021. Publications on WMHs from 2012 to 2021 were retrieved from the Web of Science Core Collection. CiteSpace 5.8.R3, VOSviewer 1.6.17, and an online bibliometric analysis platform (Bibliometric. com) were used to quantitatively analyze the trends of publications from multiple perspectives. A total of 29,707 publications on WMHs were obtained, and the number of annual publications generally increased from 2012 to 2021. Neurology had the most publications on WMHs. The top country and institution were the United States and Harvard University, respectively. Massimo Filippi and Stephen M. Smith were the most productive and co-cited authors, respectively. Thematic concentrations primarily included cerebral small vessel disease, diffusion magnetic resonance imaging (dMRI), schizophrenia, Alzheimer’s disease, multiple sclerosis, microglia, and oligodendrocyte. The hotspots were clustered into five groups: white matter and diffusion tensor imaging, inflammation and demyelination, small vessel disease and cognitive impairment, MRI and multiple sclerosis, and Alzheimer’s disease. Emerging trends mainly include deep learning, machine learning, perivascular space, convolutional neural network, neurovascular unit, and neurite orientation dispersion and density imaging. This study presents an overview of publications on WMHs and provides insights into the intellectual structure of WMH studies. Our study provides information to help researchers and clinicians quickly and comprehensively understand the hotspots and emerging trends within WMH studies as well as providing direction for future basic and clinical studies on WMHs.

Underrepresentation of women in the economics profession more pronounced in the United States compared to heterogeneous Europe

Based on a dataset that we collected from the top research institutions in economics around the globe (including universities, business schools, and other organizations, such as central banks), we document the underrepresentation of women in economics. For the 238 universities and business schools in the sample, women hold 25% of senior-level positions (full professor or associate professor) and 37% of junior-level positions. In the 82 US universities and business schools, the figures are 20% on the senior level and 32% on the entry level, while in the 122 European institutions, the numbers are 27% and 38%, respectively, with some heterogeneity across countries. The numbers also show that the highest-ranking institutions (in terms of research output) have fewer women in senior positions. Moreover, in the United States, this effect is even present on the junior level. The “leaky pipeline” may hence begin earlier than oftentimes assumed and is even more of an issue in the highly integrated market of the United States. In Europe, an institution ranked 100 places higher has 3 percentage points fewer women in senior positions, but in the United States, it is almost 5 percentage points.

A Bibliometric Analysis on How Organic Chemistry Education Research Has Evolved Collaboratively Over Time

Organic chemistry is widely regarded as a challenging topic; generally, students prefer to memorize rather than critically analyze concepts resulting in meaningful learning. In recent years, the curriculum of the organic chemistry subject has been reshaped and redefined to overcome the difficulties that students often experience while trying to understand the syllabus. The goal of this research is to illustrate the organic chemistry education’s current trends, which adopted the bibliometric analysis method. A holistic review was carried out on organic chemistry education articles obtained from the Scopus database between the year 2011 up to 2020. Based on the keywords of “organic chemistry” and “education”, the study has accumulated 1056 papers for further evaluation. Various tools have been implemented, for example, Microsoft Excel was used to conduct the frequency analysis, VOSviewer for data visualization, as well as Harzing’s Publish or Perish in regard to citation metrics and analysis. Bibliometric indicators were employed to report the findings in this study, for instance, language, subject area, research trends by year of publication, top countries, top influential institution, active source title, citation analysis, authorship analysis and keywords analysis. The results show an increasing growth rate of literature on organic chemistry education from 2011 until 2020. The United States was the top contributor to organic chemistry education research, followed by Canada. Healthy collaboration exists across researchers, countries, and institutions. This evolvement of organic chemistry education reflects a rising emphasis on Science, Technology, Engineering and Mathematics (STEM) discipline incorporated into the 21st-century curriculum to prepare the desired workforce.

Bridging the Gap: Evidence from the Return Migration of African Scientists

Although prior research has highlighted the benefits that accrue to brokers in innovation networks, much less attention is devoted to understanding who benefits from associating with a broker. This study focuses on the impact of associating with a specific kind of broker—a core/periphery bridge—that is, one that spans central and peripheral actors. I argue that actors associated with a core/periphery bridge benefit more when they have no central connection, or are outsiders in the network, due to their greater need for sponsorship from the broker. I explore this idea in the context of the return migration of American-trained scientists to African institutions, who span the core and the periphery of the global scientific network. I evaluate the impact of their return on the publication outcomes of nonmigrant scientists based in African institutions and find that following the arrival of a returnee in their institution, the nonmigrants who are not already connected to scientists in top global institutions have a greater publication output through improved access to central knowledge and connections. The findings contribute to a better understanding of how brokers can influence innovation systems more broadly.

Global Research Trends on Shale Gas from 2010–2020 Using a Bibliometric Approach

In the last few decades, shale gas resources have attracted much global attention as potential sources for clean and affordable energy. Due to this fact, coupled with the increasing energy shortfall, shale gas has become an increasingly attractive energy prospect from both an environmental and economic perspective. This development has led to the rapid growth in the number of researchers and publications in the field of shale gas. Although there are few review articles on the state of research on shale gas, the literature lacked a bibliometric analysis. This study is intended to fill the research gap by carrying out a bibliometric analysis of 9247 shale gas articles that were published between 2010 and 2020. The Web of Science database was used to collect the data. The analysis was performed to identify the most productive authors, institutions, countries, and sources, and to visualize existing collaborations as well as provide valuable information which could form the basis for establishing future collaboration. The analysis results revealed that Li J has the highest number of publications on shale gas whereas Loucks RG is the most cited author. The top three countries with the highest number of publications in shale gas research are China, USA, and Canada, while the China University of Petroleum (Beijing), China University of Geosciences, and Southwest Petroleum University China were the three top institutions with the highest number of publications. Fuel, International Journal of Coal Geology, and Marine and Petroleum Geology are the journals with the highest number of published articles on shale gas. The keyword analysis indicated that shale gas, hydraulic fracturing, pore structure, permeability, adsorption, kinetics, pyrolysis, organic matter, thermal maturity, and numerical simulation are the predominant research topics. This showed the multi-dimensional and multi-faceted character of the shale gas field. Besides, it appeared to be an exciting topic for further study that is based on a detailed evaluation of the shale gas literature. In fact, shale gas, hydraulic fracturing (fracking), CO2 sequestration, kinetic, gas adsorption, diffusion, and simulation are becoming emerging research hotspots. The bibliometric analysis that was presented in this study has revealed valuable information about the most active institutions and countries, and the most influential authors in the field of shale gas which could form the basis for establishing future collaboration. Furthermore, it can help researchers to understand the global research trend in shale gas as well as provide references for establishing future research directions.

Some of the consequences highlighted in this study include cyber-threat or attacks against businesses and individuals, political figures and government. Therefore the author examines critical cases and problems which are not just socioeconomic but also sociopolitical. The qualitative method and NCSI Index were used to analyze the cases in this study. In addition, the solutions proposed in this study includes that top technological figures, institutions and companies in Nigeria, Russia and the US need to put their cyber differences aside, move beyond the firewall protection approach and critically assess how data breach can be massively reduced if not avoided in its entirety.

The global trend of exosome in diabetes research: A bibliometric approach

Background and aimsExosome as a novel biomarker reflecting cell behavior in normal and pathological conditions such as diabetes is being the center of academic attention. Therefore, we aimed to study the research output of exosome in diabetes globally. MethodsWe conducted a bibliometric approach to analyze publications on exosome and diabetes from the beginning to 2021 based on keyword search in the Scopus. Annual publications, citations, contributions, co-authorships, and co-occurrences were analyzed and plotted using VOSviewer and GraphPad Prism. Results410 original articles and 149 reviews have published between 2009 and 2021. China and the USA were top countries in research output, sponsorship, and international collaborations. The top journals were Scientific Reports, Stem Cell Research and Therapy and Diabetes. The top institution was the University of Queensland in Australia. The top author was Chopp M. Co-occurrence analysis indicated that researchers focused on 1) extracellular vesicles in insulin resistance induced by metabolic disorders like obesity and diabetes mellitus; 2) diagnostic applicability of exosomal microRNAs as biomarkers for diabetic nephropathy; 3) therapeutic effect of exosome in wound healing and endothelial dysfunction during diabetes mellitus; and 4) The oxidative stress, autophagy, apoptosis, fibrosis, inflammation and angiogenesis mediated by exosomes during diabetes. ConclusionThe trend in research output has been increased in this field, and advanced countries are involved much more than other countries in terms of research, financial support, and international collaboration. The bibliometric results could be beneficial for further studies in better understanding of novel ideas in exosome and diabetes fields.
