      Background: Cancer as a deathly disease with high prevalence has impelled researchers to investigate its causative mechanisms in the search for effective therapeutics. Recently, the concept of phase separation has been introduced to biological science and extended to cancer research, which helps reveal various pathogenic processes that have not been identified before. As a process of soluble biomolecules condensed into solid-like and membraneless structures, phase separation is associated with multiple oncogenic processes. However, there are no bibliometric characteristics for these results. To provide future trends and identify new frontiers in this field, a bibliometric analysis was conducted in this study.Methods: The Web of Science Core Collection (WoSCC) was used to search for literature on phase separation in cancer from 1/1/2009 to 31/12/2022. After screening the literature, statistical analysis and visualization were carried out by the VOSviewer software (version 1.6.18) and Citespace software (Version 6.1.R6).
    Results: A total of 264 publications, covering 413 organizations and 32 countries, were published in 137 journals, with an increasing trend in publication and citation numbers per year. The USA and China were the two countries with the largest number of publications, and the University of Chinese Academy of Sciences was the most active institution based on the number of articles and cooperations. Molecular Cell was the most frequent publisher with high citations and H-index. The most productive authors were Fox AH, De Oliveira GAP, and Tompa P. Overlay, whilst few authors had a strong collaboration with each other. The combined analysis of concurrent and burst keywords revealed that the future research hotspots of phase separation in cancer were related to tumor microenvironments, immunotherapy, prognosis, p53, and cell death.
    Conclusion: Phase separation-related cancer research remained in the hot streak period and exhibited a promising outlook. Although inter-agency collaboration existed, cooperation among research groups was rare, and no author dominated this field at the current stage. Investigating the interfaced effects between phase separation and tumor microenvironments on carcinoma behaviors, and constructing relevant prognoses and therapeutics such as immune infiltration-based prognosis and immunotherapy might be the next research trend in the study of phase separation and cancer.

      Background: Since being recognized as an important drug-induced clinical entity during the 1960s, tardive dyskinesia (TD) has generated an extensive body of research seeking to understand its clinical characteristics, epidemiology, pathophysiology and management. Modern scientometric approaches allow interactive visualization of large bodies of literature to identify trends and hotspots within knowledge domains. This study thus aimed to provide a comprehensive scientometric review of the TD literature.Methods: Web of Science was searched for articles, reviews, editorials and letters with the term "tardive dyskinesia" in the title, abstract, or keywords through 12/31/2021. A total of 5,228 publications and 182,052 citations were included. Annual research output, prominent research areas, authors, affiliations and countries were summarized. VOSViewer and CiteSpace were used for bibliometric mapping and co-citation analysis. Structural and temporal metrics were used to identify key publications in the network.
    Results: TD-related publications peaked in the 1990s, gradually declined after 2004, and showed a further small increase after 2015. The most prolific authors were Kane JM, Lieberman JA, and Jeste DV overall (1968-2021), and Zhang XY, Correll CU and Remington G in the last decade (2012-2021). The most prolific journal was the Journal of Clinical Psychiatry overall, and the Journal of Psychopharmacology in the last decade. Knowledge clusters in the 1960-1970s dealt with clinical and pharmacological characterization of TD. In the 1980s, epidemiology, clinical TD assessment, cognitive dysfunction and animal models predominated. During the 1990s, research diverged into pathophysiological studies, especially oxidative stress, and clinical trials on atypical antipsychotics, with a focus on clozapine and bipolar disorder. In the 1990-2000s, pharmacogenetics emerged. More recent clusters include serotonergic receptors, dopamine-supersensitivity psychosis, primary motor abnormalities of schizophrenia, epidemiology/meta-analyses, and advances in TD treatment, particularly vesicular monoamine transporter-2 inhibitors since 2017.
    Conclusion: This scientometric review visualized the evolution of scientific knowledge on TD over more than five decades. These findings will be useful for researchers to find relevant literature when writing scientific articles, choosing appropriate journals, finding collaborators or mentors for research, and to understand the historical developments and emerging trends in TD research.

      BACKGROUND: Bruxism is an umbrella term that encompass a multidimensional spectrum of masticatory muscle activities.OBJECTIVE: The purpose of this study was to do a bibliometric analysis including citation-performance in the research topic of bruxism, by using an innovative method including details of article title, author keyword, KeyWords Plus, and abstracts.
    METHODS: The data was retrieved 2022-12-19 from the Clarivate Analytics Web of Science Core Collection, and the online version of the Science Citation Index Expanded (SCI-EXPANDED) for studies published 1992 to 2021. To evaluate research trends, the distribution of keywords in the article title and author-selected keywords were used.
    RESULTS: The search yielded 3,233 documents in SCI-EXPANDED, of which 2,598 were of the document-type "articles" published in 676 journals. The analysis of the articles revealed that "bruxism/sleep bruxism", "electromyography", "temporomandibular disorders", and "masticatory muscles" are the most used keywords by the authors. Further, the most frequently cited study was published 9 years ago and handles the present definition of bruxism.
    CONCLUSION: The most productive authors and those with the highest performance have some common features, they have several national and international collaborations, and they have published articles about the definition, etiology/pathophysiology and prevalence of bruxism, all senior researchers in the field of TMD. Hopefully, based on this study, researchers and clinicians will have information to be stimulated to outline future research projects on bruxism related aspects, and to initiate new international or multinational collaborations.

      Trauma-related hemorrhagic shock is a global problem. This study aimed to analyze the knowledge domain and frontiers of trauma-related hemorrhagic shock research through a bibliometric analysis. Articles on trauma-related hemorrhagic shock published between 2012 and 2022 were retrieved from the Web of Science Core Collection, and a bibliometric analysis was conducted using CiteSpace and VOSviewer. A total of 3116 articles and reviews were analyzed. These publications primarily came from 441 institutions in 80 countries, with the USA having the highest number of publications, followed by China. Among the publications, Ernest E. Moore published the most papers, whereas John B. Holcomb had the most co-citations. The most productive institution was the University of Pittsburgh in the USA. The keyword burst and reference clustering analysis indicated that "reboa," "whole blood," "exsome," "glycocalyx," "endotheliopathy," and "predictor" are new trends and developing areas of interest. With the help of CiteSpace and VOSviewer, this study provides a deeper understanding of the research landscape, frontier hotspots, and future trends in trauma-related hemorrhagic shock over the last decade. "Whole blood" instead of "component therapy" shows potential advantage while "REBOA" is increasingly discussed in rapid hemostasis. This study provides important clues for researchers to understand the knowledge domain and frontiers of this study field.

      In this bibliometric study, we analyse two of the six battery research subfields identified in the BATTERY 2030+ roadmap: Materials Acceleration Platform and Smart functionalities: Sensing. In addition, we analyse the entire research field related to BATTERY 2030+ as a whole. We (a) evaluate the European standing in the two subfields/the BATTERY 2030+ field in comparison to the rest of the world, and (b) identify strongholds of the two subfields/the BATTERY 2030+ field across Europe. For each subfield and the field as a whole, we used seed articles, i.e. articles listed in the BATTERY 2030+ roadmap or cited by such articles, in order to generate additional, similar articles located in an algorithmically obtained classification system. The output of the analysis is publication volumes, field normalized citation impact values with comparisons between country/country aggregates and between organizations, co-publishing networks between countries and organizations, and keyword co-occurrence networks.

      Purpose: This study intends to uncover a more thorough knowledge structure, research hotspots, and future trends in the field by presenting an overview of the relationship between stroke and gut microbiota in the past two decades.Method: Studies on stroke and gut microbiota correlations published between 1st January 2002 and 31st December 2021 were retrieved from the Web of Science Core Collection and then visualized and scientometrically analyzed using CiteSpace V.
    Results: A total of 660 papers were included in the study, among which the United States, the United Kingdom, and Germany were the leading research centers. Cleveland Clinic, Southern Medical University, and Chinese Academy of Science were the top three institutions. The NATURE was the most frequently co-cited journal. STANLEY L HAZEN was the most published author, and Tang WHW was the most cited one. The co-occurrence analysis revealed eight clusters (i.e., brain-gut microbiota axis, fecal microbiome transplantation, gut microbiota, hypertension, TMAO, ischemic stroke, neuroinflammation, atopobiosis). "gut microbiota," "Escherichia coli," "cardiovascular disease," "risk," "disease," "ischemic stroke," "stroke," "metabolism," "inflammation," and "phosphatidylcholine" were the most recent keyword explosions.
    Conclusion: Findings suggest that in the next 10 years, the number of publications produced annually may increase significantly. Future research trends tend to concentrate on the mechanisms of stroke and gut microbiota, with the inflammation and immunological mechanisms, TMAO, and fecal transplantation as hotspots. And the relationship between these mechanisms and a particular cardiovascular illness may also be a future research trend.

      OBJECTIVE: The French West Indies (FWI) and the Dominican Republic (DR) are also, by virtue of their geographical positions, exposed to infectious diseases. The objective of this study was to describe trends in scientific publication for the FWI and the DR using bibliometric analysis, to describe existing international collaborations for each site, and to identify directions for potential collaboration between the 2 sites.METHODOLOGY: Using data (publications from 1990-2019) from the Web of Science and PubMed databases, a bibliometric analysis was performed. Three bibliometric indicators were used: quantitative, performance, and organization-specific.
    RESULTS: There were 3599 articles published in the indicated span of time, with at least 1 author affiliated with either the FWI (N = 2552) or the DR (N = 1047). Journals ranked in the first quartile, which represent the highest quality journals in each Journal Citation Record category, were the most strongly represented, (38% for the FWI and 50.32% for the DR). In terms of the FWI publications, authors from mainland France were the primary collaborators (1754, 35%); for publications from the DR, the US provided the largest number of collaborators (898; 43%). The infectious disease category predominated, with 2 clusters emerging: arbovirus infections (FWI) and HIV infection (DR).
    CONCLUSION: This study is one of the first to perform a bibliometric analysis of the 30-year scientific output of the FWI and the DR. Both sites published articles about infectious diseases, indicating that this might be a strong area for future collaborations.

      Background: The increase in the number of pregnant women with tuberculosis is an important factor that should be analyzed at present. Thus, It is important to evaluate the bibliometric characteristics of the scientific production indexed in Scopus on complications of pregnancy and childbirth in pregnant women with tuberculosis.Methods: A cross-sectional bibliometric study was carried out analyzing the publications of journals indexed in Scopus between January 2016 and May 2022. A search strategy was developed using MESH terms and Boolean operators. The SciVal program (Elsevier) was used for bibliometric analysis of the information in the documents.
    Results: Of the 287 publications analyzed, 13 were in the International Journal of Tuberculosis and Lung Disease and BJOG: An International Journal of Obstetrics and Gynaecology presented 11.9 citations per publication. Gupta Amita, from the United States, presented the most published papers; however, Myer London, from South Africa, had the highest impact, with 17.8 citations per publication. Johns Hopkins University was the institution with the highest number of publications (34). 51.9% of the publications were in journals in the Q1 quartile while 41.8% were international collaborations.
    Conclusions: In each year analyzed, scientific production was similar, with the highest proportion of publications in journals located in the Q1 and Q2 quartile. The institutions with the highest production were from the United States and South Africa. Therefore, there is a need to promote collaborative production in countries with greater presence of this disease.

      BACKGROUND: Artificial intelligence (AI) can improve the health and well-being of older adults and has the potential to assist and improve nursing care. In recent years, research in this area has been increasing. Therefore, it is necessary to understand the status of development and main research hotspots and identify the main contributors and their relationships in the application of AI in geriatric care via bibliometric analysis.OBJECTIVE: Using bibliometric analysis, this study aims to examine the current research hotspots and collaborative networks in the application of AI in geriatric care over the past 23 years.
    METHODS: The Web of Science Core Collection database was used as a source. All publications from inception to August 2022 were downloaded. The external characteristics of the publications were summarized through HistCite and the Web of Science. Keywords and collaborative networks were analyzed using VOSviewers and Citespace.
    RESULTS: We obtained a total of 230 publications. The works originated in 499 institutions in 39 countries, were published in 124 journals, and were written by 1216 authors. Publications increased sharply from 2014 to 2022, accounting for 90.87% (209/230) of all publications. The United States and the International Journal of Social Robotics had the highest number of publications on this topic. The 1216 authors were divided into 5 main clusters. Among the 230 publications, 4 clusters were modeled, including Alzheimer disease, aged care, acceptance, and the surveillance and treatment of diseases. Machine learning, deep learning, and rehabilitation had also become recent research hotspots.
    CONCLUSIONS: Research on the application of AI in geriatric care has developed rapidly. The development of research and cooperation among countries/regions and institutions are limited. In the future, strengthening the cooperation and communication between different countries/regions and institutions may further drive this field's development. This study provides researchers with the information necessary to understand the current state, collaborative networks, and main research hotspots of the field. In addition, our results suggest a series of recommendations for future research.

      Purpose: Clinical treatment of knee osteoarthritis has gained great interest, and numerous clinical studies have been reported. Few studies have described the detailed characterizations of clinical trials on knee osteoarthritis. This study is to identify, visualize, and characterize the clinical trials in knee osteoarthritis research.Design and Methods: Articles published in recent two decades were extracted from the Web of Science core collection database using a query based on MeSH terms and topics of knee osteoarthritis and clinical trial. Basic characteristics of publications were analyzed based on the publication year, authors, institutions, counties, and keywords covered in the article. CiteSpace and VOS viewer were used for data visualization. The data were retrieved on May 28, 2022.
    Results: A total of 1972 trials on knee osteoarthritis were identified. The number of publications has experienced rapid growth in the past two decades. America, England, and China had strong contributions in publication. Osteoarthritis and Cartilage, Annals of the Rheumatic Diseases and American Journal of Sports Medicine were highly cited and bellwether journals. Clustering mapping of the collaborative network, co-citation, and co-occurrence analyses showed that the research hotspots are mainly focused on disease-modifying medications, intra-articular injections, physical therapy for symptom control, lifestyle intervention, Chinese medicine treatment, and knee replacement.
    Conclusion: Clinical treatments of knee OA are evolving. Pharmacologic therapy, intra-articular therapy, nonpharmacologic therapy including exercise or diet, self-management programs, Chinese medicine treatment, and knee replacement were highly represented in clinical trials of knee OA. Adjustment of combination therapy may be the next study focus in the future.

      BACKGROUND: This study endeavors to scrutinize the hotspots and trends in the literature concerning the internal fixation of femoral neck fractures (INFNF) through a comprehensive bibliometric analysis. Notably, this analytical process encompasses both qualitative and quantitative components.METHODS: The present study has utilized the Science Citation Index-Expanded from the Web of Science Core Collection to extract datasets ranging from January 1, 2010, to August 31, 2022. Quantitative analysis was carried out using sophisticated analytical tools such as the Bibliographic Item Co-Occurrence Matrix Builder, the Online Analysis Platform of Literature Metrology, and CiteSpace software. Further, the major Medical Subject Headings terms and their subheading counterparts associated with INFNF were extracted from the PubMed2XL website using the corresponding PMIDs. These Medical Subject Headings terms were employed in conducting a co-word clustering analysis. Ultimately, the Graphical CLUstering TOolkit program was utilized to execute a co-word biclustering analysis to discern the prevailing hotspots in this domain.
    RESULTS: Between January 1, 2010, and August 31, 2022, a total of 463 publications were issued on INFNF. The INJURY-INTERNAL JOURNAL OF THE CARE OF THE INJURED stood out as the most extensively perused journal in this area. Notably, China emerged as the foremost contributor to publishing articles within the last 12 years, followed by the United States and Canada. McMaster University was identified as the leading institution in INFNF research, while Bhandari M emerged as the most prolific author in this field. Moreover, the study identified five notable research hotspots within the domain of INFNF.
    CONCLUSIONS: This study has identified five critical areas of research in the field of INFNF. It suggests that the primary focus of future research is likely to center on advancing internal fixation methods and robot-assisted instrumentation for femoral neck fractures. As such, this study provides valuable insights into future research directions and ideas for those working in this field.

      Background: Heart failure is a common cardiovascular disease that imposes a heavy clinical and economic burden worldwide. Previous research and guidelines have supported exercise training as a safe, effective, and cost-efficient treatment to intervene in heart failure. The aim of this study was to analyze the global published literature in the field of exercise training for heart failure from 2002 to 2022, and to identify hot spots and frontiers within this research field.Methods: Bibliometric information on literature on the topic of exercise training for heart failure published between 2002 and 2022 was searched and collected in the Web of Science Core Collection. CiteSpace 6.1.R6 (Basic) and VOSviewer (1.6.18) were applied to perform bibliometric and knowledge mapping visualization analyses.
    Results: A total of 2017 documents were retrieved, with an upward-stable trend in the field of exercise training for heart failure. The US authors were in the first place with 667 documents (33.07%), followed by Brazilian authors (248, 12.30%) and Italian authors (182, 9.02%). The Universidade de São Paulo in Brazil was the institution with the highest number of publications (130, 6.45%). The top 5 active authors were all from the USA, with Christopher Michael O'Connor and William Erle Kraus publishing the most documents (51, 2.53%). The International Journal of Cardiology (83, 4.12%) and the Journal of Applied Physiology (78, 3.87%) were the two most popular journals, while Cardiac Cardiovascular Systems (983, 48.74%) and Physiology (299, 14.82%) were the two most popular categories. Based on the results of keyword co-occurrence network and co-cited reference network, the hot spots and frontiers of research in the field of exercise training for heart failure were high-intensity interval training, behaviour therapy, heart failure with preserved ejection fraction, and systematic reviews.
    Conclusion: The field of exercise training for heart failure has experienced two decades of steady and rapid development, and the findings of this bibliometric analysis provide ideas and references for relevant stakeholders such as subsequent researchers for further exploration.

      BACKGROUND: Numerous studies have explored the most productive and influential authors in a specific field. However, 2 challenges arise when conducting such research. First, some authors may have identical names in the study data, and second, the contributions of coauthors may vary in the article by line, requiring consideration. Failure to address these issues may result in biased research findings. Our objective was to illustrate how the author-weighted scheme (AWS) and betweenness centrality (BC) can be employed to identify the 10 most frequently cited authors in a particular journal and analyze their research themes.METHODS: We collected 24,058 abstracts from the PubMed library between 2000 and 2020 using the keyword "Medicine [Journal]." Author names, countries/regions, and medical subject headings (MeSH terms) were collected. The AWS to identify the top 10 authors with a higher x-index was applied. To address the issue of authors with identical names affiliated with different research institutes, we utilized the BC method. Social network analysis (SNA) was conducted, and 10 major clusters were identified to highlight authors with a higher x-index within the corresponding clusters. We utilized SNA to analyze the MeSH terms from articles of the 10 top-cited authors to identify their research themes.
    RESULTS: Our findings revealed the following: within the top 10 cited authors, 2 authors from China shared identical names with Jing Li and Tao-Wang; JA Winkelstein from Maryland (US) had the highest x-index (15.58); Chia-Hung Kao from Taiwan was the most prolific author, having published 115 articles in Medicine since 2003; and the 3 primary research themes, namely, complications, etiology, and epidemiology, were identified using MeSH terms from the 10 most frequently cited authors.
    CONCLUSIONS: Using AWS and BC, we identified the top 10 most cited authors. The research methods we utilized in this study (BC and AWS) have the potential to be applied to other bibliometric analyses in the future.

      BACKGROUND: Considerable interest has been devoted to quantifying research productivity for the purposes of academic appointment and promotion in plastic surgery. A novel bibliometric, the relative citation ratio (RCR), integrates features unavailable in prior metrics, such as the h-index, including the ability to compare researchers in distinct fields. This investigation examines the RCR in relation to established measures of academic productivity and provides the benchmark data in plastic surgery.METHODS: Online sources were queried to identify the characteristics of 955 academic plastic surgeons from 94 programs, ie, academic rank, gender, degrees, and fellowships. Bibliometric data were acquired using the iCite and Scopus databases. Comparative and correlational analyses of variables were performed.
    RESULTS: Academic plastic surgeons were exceptionally productive, with a mean RCR of 1.20 (interquartile range, 0.79-1.67) and a weighted RCR of 17.68 (interquartile range, 5.14-52.48). Increased mean RCR was significantly associated with advanced academic rank and fellowship training. Increased weighted RCR was significantly associated with advanced academic rank, male gender, PhD acquisition, publication experience, and fellowship training. The h-index was weakly correlated with mean RCR but strongly correlated with weighted RCR and publication experience.
    CONCLUSIONS: The RCR was associated with established markers of academic productivity, indicating its validity as a reliable field-normalized measure for the evaluation of plastic surgery faculty. Because scholarly output is a potential factor with respect to decisions of hiring, promotion, and allocation of funding, this modality of standardized comparison is paramount for plastic surgeons who exist within a larger general surgery department.

      BACKGROUND: Aphasia is one of the most devastating cognitive disorders caused by brain injury and seriously hinders patients' rehabilitation and quality of life. Repetitive transcranial magnetic stimulation involves the repeated application of extracranial pulsed magnetic fields to the local central nervous system to alter the membrane potential of cortical nerve cells, generating induced currents that affect brain metabolism and electrical activity. As one of the most popular noninvasive brain stimulation techniques, it has been used to treat aphasia. However, only a few bibliometric studies have examined the research direction and main findings in the field.METHODS: To obtain an in-depth understanding of the research status and trend in this area, a bibliometric analysis based on the Web of Science database was conducted. VOSviewer (Leiden University, Leiden, Netherlands) and Microsoft Excel (Microsoft, Redmond, USA) were used to extract bibliometric information. Analysis of global distribution was conducted using the webpage mapping implement GunnMap2 (http://lert.co.nz/map/).
    RESULTS: Publications in this field were retrieved from the Web of Science Core Collection database, and 189 articles met the final inclusion criteria. The most influential authors, institutions, journals, and countries were Ralph MA from the University of Manchester, Harvard University, Neuropsychologia, and the USA, respectively.
    CONCLUSION: This study revealed publication patterns and emerging trends in the literature, providing a detailed and objective overview of the current state of research on repetitive transcranial magnetic stimulation for the treatment of aphasia. This information will be of great benefit to anyone seeking information about this field and can serve as a reference guide for researchers aiming to conduct further research.

      Biochar has excellent physical and chemical properties such as porosity, high carbon content, high cation exchange capacity, and rich surface functional groups and has been widely used in environmental remediation. Over the past 20 years, although various reviews have described the application of biochar as an environmentally friendly multifunctional material in environmental remediation, no comprehensive summary and analysis of the research trends in this field exists. To promote the rapid and stable development of the field of biochar, the current state of research on biochar is clarified using the bibliometric method in this report, and potential development directions and challenges for the future are identified. All relevant biochar literature from 2003-2023 was collected from the Chinese National Knowledge Infrastructure and Web of Science Core Collection. A total of 6,119 published Chinese papers and 25,174 English papers were selected for the quantitative analysis. CiteSpace, VOSviewer, and Scimago graphics software was used to summarize the numbers of papers published over the years, as well as the countries, institutions, and authors that published the most articles. Secondly, using keyword co-occurrence and emergence analysis, the recognized research hotspots in different areas such as adsorbents, soil remediation, catalytic oxidation, supercapacitors, and "biochar-microbial" synergy were analyzed. Finally, the prospects and challenges of biochar were assessed to provide new perspectives for further promoting its development in technological, economic, environmental, and other aspects.

      Background: The size and function of the future liver remnant (FLR) is an essential consideration for both eligibility for treatment and postoperative prognosis when planning surgical hepatectomy. Over time, a variety of preoperative FLR augmentation techniques have been investigated, from the earliest portal vein embolization (PVE) to the more recent Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) and liver venous deprivation (LVD) procedures. Despite numerous publications on this topic, no bibliometric analysis has yet been conducted.Methods: Web of Science Core Collection (WoSCC) database was searched to identify studies related to preoperative FLR augmentation techniques published from 1997 to 2022. The analysis was performed using the CiteSpace [version 6.1.R6 (64-bit)] and VOSviewer [version 1.6.19].
    Results: A total of 973 academic studies were published by 4431 authors from 920 institutions in 51 countries/regions. The University of Zurich was the most published institution while Japan was the most productive country. Eduardo de Santibanes had the most published articles, and Masato Nagino was the most frequently co-cited author. The most frequently published journal was HPB, and the most cited journal was Ann Surg, with 8088 citations. The main aspects of preoperative FLR augmentation technique is to enhance surgical technology, expand clinical indications, prevent and treat postoperative complications, ensure long-term survival, and evaluate the growth rate of FLR. Recently, hot keywords in this field include ALPPS, LVD, and Hepatobiliary Scintigraphy.
    Conclusion: This bibliometric analysis provides a comprehensive overview of preoperative FLR augmentation techniques, offering valuable insights and ideas for scholars in this field.

      Citation analysis is used extensively in the bibliometrics literature to assess the impact of individual works, researchers, institutions, and even entire fields of study. In this article, we analyze citations in one large and influential field within computer science, namely computer systems. Using citation data from a cross-sectional sample of 2,088 papers in 50 systems conferences from 2017, we examine four research areas of investigation: overall distribution of systems citations; their evolution over time; the differences between databases (Google Scholar and Scopus), and; the characteristics of self-citations in the field. On citation distribution, we find that overall, systems papers were well cited, with the most cited subfields and conference areas within systems being security, databases, and computer architecture. Only 1.5% of papers remain uncited after five years, while 12.8% accrued at least 100 citations. For the second area, we find that most papers achieved their first citation within a year from publication, and the median citation count continued to grow at an almost linear rate over five years, with only a few papers peaking before that. We also find that early citations could be linked to papers with a freely available preprint, or may be primarily composed of self-citations. For the third area, it appears that the choice of citation database makes little difference in relative citation comparisons, despite marked differences in absolute counts. On the fourth area, we find that the ratio of self-citations to total citations starts relatively high for most papers but appears to stabilize by 12-18 months, at which point highly cited papers revert to predominately external citations. Past self-citation count (taken from each paper's reference list) appears to bear little if any relationship with the future self-citation count of each paper. The primary practical implication of these results is that the impact of systems papers, as measured in citations, tends to be high relative to comparable studies of other fields and that it takes at least five years to stabilize. A secondary implication is that at least for this field, Google Scholar appears to be a reliable source of citation data for relative comparisons.

      Background: Benign paroxysmal positional vertigo is the most common disease in which vertigo is the main clinical manifestation, and it has become a global medical problem, affecting a wide range of areas and seriously affecting the quality of human life.Objective: This article presents an analysis of the current characteristics of BPPV-related research and summarizes the current hot topics and trends, with the goal of inspiring future research into the prevention and treatment of BPPV, thereby improving the differential diagnosis and prevention of peripheral vertigo.
    Methods: A bibliometric approach was used to collect 1,219 eligible studies on BPPV from four databases-PubMed, Embase, Scopus, and Web of Science-published between 1974 and 2022. The characteristics and status of the accumulated scientific output were processed using R and VOSviewer so that we could visualize any trends or hotspots.
    Results: The results showed a significant increase in the annual number of publications, with an average annual growth rate of 21.58%. A possible reason for the especially pronounced peak in 2021 was an increase in the prevalence of BPPV as a result of COVID-19. The new coronavirus became a focus of research in 2021. A total of 3,876 authors (of whom 1,097 were first authors) published articles in 307 different journals; 15.7% of the articles were published in Acta Oto-Larygologica, Otology and Neurotology, and Frontiers in Neurology. Acta Oto-Laryngologica was well ahead of the other journals in terms of growth rate and number of articles published. American scholars generated the largest number of articles overall, and the USA was involved in the greatest number of international collaborations, followed by Italy and China. The themes of the research centered around three topics, namely the treatment of BPPV, its influencing factors, and diagnosis.
    Conclusions: There has been a major increase in BPPV-related research over the last 50 years, leading to an increase in related articles and rapid development of the field. Key directions for future research include the improvement of individualized treatment for residual symptoms after initial treatment of BPPV among the elderly; effective control of comorbidities such as osteoporosis; and secondary inner ear disease, such as Ménière's disease.

      BACKGROUND: Crohn's disease represents a challenge for patients concerned with the modified diet regimen as well as practitioners who seek the best nutritional therapy. Crohn's disease can alter the body's ability to digest food and to absorb nutrients, resulting in severe vitamin deficiencies, malnutrition and sometimes life-threatening complications. However, a comprehensive bibliometric analysis is lacking to map the current links between nutrition and Crohn's disease in terms of the number of citations, geographic distribution and growth trends of publications.AIM: To introduce the current state of research as well as hotspots in the field of nutrition and Crohn's disease from a bibliometric standpoint.
    METHODS: We searched the Scopus database and selected the relevant literature on nutrition and Crohn's disease that met the inclusion criteria. We analyzed the publication trends and research hotspots by using video object segmentation viewer software.
    RESULTS: We included 1237 publications. The number of documents published each year has increased steadily. The United States and the University of Otago, Christchurch, have had the highest productivity, with 208 (16.81%) and 29 (2.34%) documents, respectively. The "role of exclusive enteral nutrition for complicated Crohn's disease" and "manipulation of the gut microbiota as a key target for Crohn's disease" were the major research areas in 2016-2021, and they could be extensively investigated in the future. Meanwhile, research on "malnutrition in patients with Crohn's disease" appeared to be an area that attracted more research attention before 2016.
    CONCLUSION: This is the first bibliometric analysis to map the knowledge structure and trends regarding nutrition in Crohn's disease research over the past two decades. The results provide a comprehensive summary and identification of the frontiers of nutrition and Crohn's disease-related research, which may be used as a resource by researchers in the field.

      BACKGROUND: Network meta-analyses (NMAs) are statistical techniques used to synthesize data from multiple studies and compare the effectiveness of different interventions for a particular disease or condition. They have gained popularity in recent years as a tool for evidence-based decision making in healthcare. Whether publications in NMAs have an increasing trend is still unclear. This study aimed to investigate the trends in the number of NMA articles over the past 10 years when compared to non-NMA articles.METHODS: The study utilized data from the Web of Science database, specifically searching for articles containing the term "meta-analysis" published between 2013 and 2022. The analysis examined the annual number of articles, as well as the countries, institutions, departments, and authors associated with the articles and the journals in which they were published. Ten different visualization techniques, including line charts, choropleth maps, chord diagrams, circle packing charts, forest plots, temporal heatmaps, impact beam plots, pyramid plots, 4-quadrant radar plots, and scatter plots, were employed to support the hypothesis that the number of NMA-related articles has increased (or declined) over the past decade when compared to non-NMA articles.
    RESULTS: Our findings indicate that there was no difference in mean citations or publication trends between NMA and non-NMA; the United States, McMaster University (Canada), medical schools, Dan Jackson from the United Kingdom, and the Journal of Medicine (Baltimore) were among the leading entities; NMA ranked highest on the coword analysis, followed by heterogeneity, quality, and protocol, with weighted centrality degrees of 32.51, 30.84, 29.43, and 24.26, respectively; and the number of NMA-related articles had increased prior to 2020 but experienced a decline in the past 3 years, potentially due to being overshadowed by the intense academic focus on COVID-19.
    CONCLUSION: It is evident that the number of NMA articles increased rapidly between 2013 and 2019 before leveling off in the years following. For researchers, policymakers, and healthcare professionals who are interested in evidence-based decision making, the visualizations used in this study may be useful.

      Background: Sharing knowledge such as resources, research results, and scholarly documents, is of key importance to improving collaboration between researchers worldwide. Research results from the field of artificial intelligence (AI) are vital to share because of the extensive applicability of AI to several other fields of research. This has led to a significant increase in the number of AI publications over the past decade. The metadata of AI publications, including bibliometrics and altmetrics indicators, can be accessed by searching familiar bibliographical databases such as Web of Science (WoS), which enables the impact of research to be evaluated and identify rising researchers and trending topics in the field of AI.Problem description: In general, bibliographical databases have two limitations in terms of the type and form of metadata we aim to improve. First, most bibliographical databases, such as WoS, are more concerned with bibliometric indicators and do not offer a wide range of altmetric indicators to complement traditional bibliometric indicators. Second, the traditional format in which data is downloaded from bibliographical databases limits users to keyword-based searches without considering the semantics of the data.
    Proposed solution: To overcome these limitations, we developed a repository, named AI-SPedia. The repository contains semantic knowledge of scientific publications concerned with AI and considers both the bibliometric and altmetric indicators. Moreover, it uses semantic web technology to produce and store data to enable semantic-based searches. Furthermore, we devised related competency questions to be answered by posing smart queries against the AI-SPedia datasets.
    Results: The results revealed that AI-SPedia can evaluate the impact of AI research by exploiting knowledge that is not explicitly mentioned but extracted using the power of semantics. Moreover, a simple analysis was performed based on the answered questions to help make research policy decisions in the AI domain. The end product, AI-SPedia, is considered the first attempt to evaluate the impacts of AI scientific publications using both bibliometric and altmetric indicators and the power of semantic web technology.

      Background: The COVID-19 pandemic has significantly impacted public health, putting people with Alzheimer's disease at significant risk. This study used bibliometric analysis method to conduct in-depth research on the relationship between COVID-19 and Alzheimer's disease, as well as to predict its development trends.Methods: The Web of Science Core Collection was searched for relevant literature on Alzheimer's and Coronavirus-19 during 2019-2023. We used a search query string in our advanced search. Using Microsoft Excel 2021 and VOSviewer software, a statistical analysis of primary high-yield authors, research institutions, countries, and journals was performed. Knowledge networks, collaboration maps, hotspots, and regional trends were analyzed using VOSviewer and CiteSpace.
    Results: During 2020-2023, 866 academic studies were published in international journals. United States, Italy, and the United Kingdom rank top three in the survey; in terms of productivity, the top three schools were Harvard Medical School, the University of Padua, and the University of Oxford; Bonanni, Laura, from Gabriele d'Annunzio University (Italy), Tedeschi, Gioacchino from the University of Campania Luigi Vanvitelli (Italy), Vanacore, Nicola from Natl Ctr Dis Prevent and Health Promot (Italy), Reddy, P. Hemachandra from Texas Tech University (USA), and El Haj, Mohamad from University of Nantes (France) were the authors who published the most articles; The Journal of Alzheimer's Disease is the journals with the most published articles; "COVID-19," "Alzheimer's disease," "neurodegenerative diseases," "cognitive impairment," "neuroinflammation," "quality of life," and "neurological complications" have been the focus of attention in the last 3 years.
    Conclusion: The disease caused by the COVID-19 virus infection related to Alzheimer's disease has attracted significant attention worldwide. The major hot topics in 2020 were: "Alzheimer' disease," COVID-19," risk factors," care," and "Parkinson's disease." During the 2 years 2021 and 2022, researchers were also interested in "neurodegenerative diseases," "cognitive impairment," and "quality of life," which require further investigation.

      Objective: At present, there is no feature description of the mechanism of pelvic organ prolapse (POP) in the literature. This study aimed to map the emerging trends regarding the mechanism of POP from inception to 2022 by bibliometric analysis and to analyze its research hotspots and frontiers.Methods: We downloaded pertinent publications from inception to 2022 from the Web of Science Core Collection (WoSCC) on 30 June 2022. The data were then examined using the Bibliometrix program in R (Version 4.1.0), CiteSpace software, the Online Analysis Platform of Literature Metrology (https://bibliometric.com), and a bibliometrix online interface.
    Results: A total of 290 qualified records on the mechanism of POP were identified and included in the analysis. The most productive journal was International Urogynecology Journal. Bump RC and Olsen AL were the most cited authors. Extracellular matrix, collagen, apoptosis, elastin, oxidative stress, gene expression, matrix metalloproteinase, and tissue engineering were among the 25 most relevant terms. According to the analysis of trending topics, tissue engineering has become a new research hotspot.
    Conclusion: Extracellular matrix remodeling, oxidative stress and apoptosis are the three main directions for studying the mechanism of POP. In addition, tissue engineering has become a new research hotspot. In the future, in-depth research on the interaction between different mechanisms will be carried out, and attempts will be made to combine biomimetic materials and seed cells to achieve the regeneration and reconstruction of POP-related organs.

      First and last authorship are important metrics of productivity and scholarly success for trainees and professors. For 11 drug delivery-related journals in 2021, the percentage of female first (39.5%) and last (25.7%) authorship was reported. A strong negative correlation, with female first (rp = -0.73) and female last authorship (rp = -0.66), was observed with respect to journal impact factor. In contrast, there was a strong positive correlation with male first and last authorship (rp = 0.71). Papers were ∼1.5 times more likely to have a male first author, and ∼3 times more likely to have a male last author, than females. A female was 22% more likely to have first authorship if the last author was female, although there is an ∼1% increase per year in female authorship with male last authorship, which equates to equality in first authorship by 2044. Considering that drug delivery is composed of engineering, chemistry, and pharmaceutical science disciplines, the observed 25.7% female last authorship does not represent the approximately 35.5% to 50% of professors that are female in these disciplines, internationally. Overall, female authorship in drug delivery-related journals should improve to better represent the work of female senior authors.

      BACKGROUND: Scientific comparative advantage is measured by using a specialization index (SI) of article citations. The profile data have been published in the literature. However, no such research has been conducted to determine which countries dominate the field of computer science (CS) (subject category [SC]) using the SI. A KIDMAP in the Rasch model has been applied to the display of individual student performance in school. Based on the SI of article citations, we used KIDMAP to determine whether China dominates the field of CS.METHODS: The data were derived from published research in the Web of Science, which included 199 countries and 254 subject categories (SC, between 2010 and 2019). A total of 96 SC related to biomedicine were extracted. We examined 7 factors associated with CS using exploratory factor analysis. Based on the SI in CS under the Rasch model, 1-dimensional SCs on CS were displayed on Wright Maps and KIDMAPs. An analysis of the dominance of CS in China was presented on the basis of a scatter plot.
    RESULTS: Our findings indicate that (1) CS domains are divided into 2 groups (traditional and advanced domains); (2) no evidence has been found that China dominates CS; based on SI indicators, China was ranked third with --2.62 and 0.79 logits after Taiwan and Slovenia (-(-2.62 and 9.24 logits in Factors 1 and 2) in the period from 2010 to 2019.
    CONCLUSIONS: There is insufficient evidence to demonstrate that China has a dominant role over other countries/regions despite ranking third in CS. In future studies, it is recommended to include a KIDMAP visual to assess dominant roles in other areas of research, rather than to confine ourselves to CS as we did in this study.

      BACKGROUND: An Alluvial diagram illustrates the flow of values from one set to another. Edges (or links/connections) are the connections between nodes (or actors/ vertices). There has been an increase in the use of Alluvial deposits in medical research in recent years. However, there was no illustration of such research on the way to draw the Alluvial for the readers. Our objective was to demonstrate how to draw the Alluvial in Microsoft Excel by using 2 examples, including variable characteristics for COVID-19 patients and research achievements (RAs) on the topic of COVID-19, epidemiology, pathogenesis, and vaccine (CEPV), and provide an easy and friendly method of drawing the Alluvial in MS Excel.METHODS: Blood samples were collected and analyzed from 485 infected individuals in Wuhan, China. An operational decision tree and 2 Alluvial diagrams were shown to be capable of identifying variable characteristics in COVID-19 patients. A second example is the 100 top-cited articles downloaded from the Web of Science core collection (WoSCC) on the CEPV topic. On the Alluvial diagram, the mean citations (=citations/publications) and x-index were used to identify the top 5 members with the highest RAs in each entity (country, institute, journal, and research area). Two examples (i.e., blood samples taken from 485 infected individuals in Wuhan, China, and 100 top-cited articles on the CEPV topic) were illustrated and compared with traditional visualizations without flow relationships between nodes.
    RESULTS: The top members in entities with the x-index are U Arab Emirates (242), Jama-J. Am. Med. Assoc. (27.18), Lancet (58.34), San Francisco Va Med (178), and Chaolin Huang (189) in countries, institutes, departments, and authors, respectively. The most cited article with 1315 citations was written by Huang and his colleagues and published by Lancet in 2021.
    CONCLUSION: This study generates several Alluvial diagrams as demonstrations. The tutorial material and MP4 video provided in the Excel module allow readers to draw the Alluvial on their own in an easy and friendly manner.

      OBJECTIVE: Research experience is one criterion of the selection process for applicants to residency training programs. We aim to quantify temporal trends in research productivity of medical students who matched into a canadian ophthalmology residency program.DESIGN: Retrospective database review.
    PARTICIPANTS: A total of 465 residents commencing ophthalmology training from 2010 to 2022 in 15 Canadian ophthalmology residency programs.
    METHODS: The names of all residents commencing training in ophthalmology in all Canadian programs from 2010 to 2022 were identified. Bibliometric data including publication count and type, authorship position, and H-index corresponding to the match year were extracted from the Scopus database. Descriptive and univariate statistics were used to characterize and assess trends in research productivity.
    RESULTS: A total of 461 ophthalmology residents (99% complete data set) from all 15 residency programs representing 1179 publications, including 679 ophthalmology-related publications, were identified. Most publications were original research (676; 58%), followed by case reports and letters (324; 27%) and reviews (162; 14%). Overall, 62% of residents had at least 1 publication at the time of the match, with a mean of 2.56 ± 3.49 publications and a mean H-index of 1.03 ± 1.48 publications. There was a significant increase (p < 0.001) in all research productivity metrics except senior authorship in the period 2019-2022 compared with 2010-2018. Notably, 91% of residents had ≥1 publication in 2022 compared with 38% in 2010.
    CONCLUSION: First-year ophthalmology resident publication productivity doubled from 2010-2016 to 2017-2022 suggesting a greater emphasis on scholarly work from medical trainees, a trend similar to that reported in other specialties.

      BACKGROUND: The use of social media assists in the distribution of information about COVID-19 to the general public and health professionals. Alternative-level metrics (Altmetrics) is an alternative method to traditional bibliometrics that assess the amount of sharing and spreading of a scientific article on social media platforms.OBJECTIVE: Our objective was to characterize and compare traditional bibliometrics (citation-count) with newer metrics (Altmetric Attention Score) of the top 100 Altmetric scored COVID-19 articles.
    METHODS: The 100 highest Altmetric Attention Score (AAS) articles were identified utilizing the Altmetric explorer in May 2020. AAS, journal name, and mentions from various social media databases (Twitter, Facebook, Wikipedia, Reddit, Mendeley, Dimension) of each article were collected. Citation-counts were collected from the Scopus database.
    RESULTS: The median AAS and citation-count were 4922.50 and 24.00, respectively. Of 100 articles, The New England Journal of Medicine published the most articles at 18% (18/100). Twitter was the most frequently used social media platform with 96.3% of the mentions (985,429/1,022,975). Positive correlations were seen between AAS and citation-count (r2=.0973; P=.002).
    CONCLUSIONS: Our research characterized the top 100 articles by AAS regarding COVID-19 in the Altmetric database. Altmetrics could complement with traditional citation-count when assessing the dissemination of an article regarding COVID-19.

      HIV literature has grown exponentially since it was named the virus that causes acquired immunodeficiency syndrome (AIDS). Bibliometric analysis is a practical approach for quantitatively and qualitatively assessing scientific research. This work aims to describe HIV research output in Africa by country from 1986 until 2020. We conducted a search of the PubMed database in June 2021 for a 35-year period spanning 1986 to 2020. We comparatively weighed for countries' populations, gross domestic product (GDP), and the number of persons living with HIV (PLHIV) by calculating the ratio of the number of publications from each country. We used Poisson regression models to explore the trends in countries' HIV research output over the study period. The Pearson correlation analysis assessed the association between research output, population size, GDP, and the number of PLHIV.A total of 83,527 articles from African countries on HIV indexed in PubMed were included for analysis. Republic of South Africa, Uganda, Kenya, and Nigeria account for 54% of the total indexed publications with 33.2% (26,907); 8.4% (7,045); 7.3% (6,118); and 5.1% (4,254), respectively. Africa's proportion of the world's total HIV publications increased from 5.1% in 1986 to 31.3% in 2020. There was a strong positive and statistically significant correlation between the total indexed HIV publications and countries' GDP (r = 0.59, P<0.01), population (r = 0.58, P<0.01), and the estimated number of PLHIV (r = 0.72, P<0.01). The study found that Africa's contribution to global HIV research output increased over the 35 years, but it remains relatively low compared to the continent's burden of HIV infections. Our findings also revealed major differences in research output across sub-regions in Africa, with the Republic of South Africa having the highest output. The factors associated with HIV research output were economic strength, disease epidemiology, and population size.

      Marine accidents are a significant issue that can lead to loss of life, damage to ships and cargo, and harm to the marine environment. To gain better understanding of scientific awareness of marine accidents occurred in European countries, this study conducted a bibliometric and correspondence analysis of the scientific literature. Bibliometric analysis was employed to examine various publications, which were released during the period between 2012 and December 2022. Moreover, correspondence analysis was used to classify and analyze marine accidents based on the severity and the consequence of the accidents. The findings indicate that scientific awareness of researchers in countries where serious and very serious marine accidents occur is also high. However, Norway stands out as the country with the highest scientific awareness of researchers despite experiencing marine accidents with less serious. The most significant factor contributing to the prominence of researchers here is their collaborations with researchers from other countries. Overall, this study sheds light on the need for further research and action to improve marine accident prevention. Collaborative efforts involving researchers, maritime stakeholders, and policymakers are necessary to address the complex challenges of marine accidents and to ensure the maritime safety and protection of the marine environment.

      Purpose: To measure the research productivity of trainees from the University of Toronto's Medical Imaging Clinician Investigator Program (MI-CIP) and comparing it with the research productivity of trainees from MI-non-CIP and General Surgery (GSx) Clinician Investigator Program. Methods: We identified residents who completed an MI-CIP, MI-non-CIP and GSx-CIP from 2006-2016. In each group of trainees, we assessed 3 research productivity outcomes with non-parametric tests before residency and at 7 years post-CIP completion/post-graduation. Research productivity outcomes include the number of total publications, the number of first-author publications, and the publication's average journal impact factor (IF). Results: We identified 11 MI-CIP trainees (male/female: 9 [82%]/2 [18%]), 74 MI-non-CIP trainees (46 [62%]/28 [38%]) and 41 GSx-CIP trainees (23 [56%]/18 [44%]). MI-CIP trainees had statistically significant higher research productivity than MI-non-CIP in all measured outcomes. The median (interquartile range, IQR) number of total publications of MI-CIP vs MI-non-CIP trainees was 5.0 (8.0) vs 1.0 (2.0) before residency and 6.0 (10.0) vs .0 (2.0) at 7 years post-CIP completion/post-graduation. The median (IQR) first-author publications of MI-CIP vs MI-non-CIP trainees was 2.0 (3.0) vs .0 (1.0) before residency and 2.0 (4.0) vs (.0) (1.0) at 7 years post-CIP completion/post-graduation. The median (IQR) average journal IF of MI-CIP vs MI-non-CIP trainees was 3.2 (2.0) vs .3 (2.4) before residency and 3.9 (3.2) vs .0 (2.6) at 7 years post-CIP completion/post-graduation. Between MI-CIP and GSx-CIP trainees, there were no significant differences in research productivity in all measured outcomes. Conclusion: MI-CIP trainees actively conducted research after graduation. These trainees demonstrated early research engagement before residency. The similar research productivity of MI-CIP vs GSx-CIP trainees shows initial success of MI-CIP trainees.

      Background: Nrf2, an essential and fascinating transcription factor, enjoys a dual property in the occurrence and development of inflammation and cancer. For over two decades, numerous studies regarding Nrf2 in cancer have been reported, whereas there is still a lack of a scientometrics and visualization analysis of Nrf2 in cancer. Hence, a scientometric study regarding the oxidative stress modulator Nrf2 was implemented.Methods: After the quality screening, we defined 7168 relevant studies from 2000 to 2021. CiteSpace, VOSviewer, R software, and GraphPad Prism were used for the following scientometric study and visualization analysis, including field profiles, research hotspots, and future predictions.
    Results: The total number of publications and citations are 1058 and 54,690, respectively. After polynomial fitting curve analysis, two prediction functions of the annual publication number (y = 3.3909x2 - 13585x + 1 E+07) and citation number (185.45x2 - 743669x + 7 E+08) were generated. After scientometric analysis, we found that Biochemistry Molecular Biology correlates with Nrf2 in cancer highly, and Free Radical Biology and Medicine is a good choice for submitting Nrf2-related manuscripts. The current research hotspots of Nrf2 in cancer mainly focus on cancer therapy and its cellular and molecular mechanisms. "antioxidant response element (87.5)", "gene expression (43.98)", "antioxidant responsive element (21.14)", "chemoprevention (20.05)", "carcinogenesis (19.2)", "cancer chemoprevention (18.45)", "free radical (17.15)", "response element (14.17)", and "chemopreventive agent (14.04)" are important for cancer therapy study. In addition, "glutathione-S-transferase (47)", "keap1 (15.39)", and "heme oxygenase 1 gene (24.35)" are important for inflammation and cell fate study. More interestingly, by performing an "InfoMap" algorithm, the thematic map showed that the "immune response" is essential to oxidative stress modulator Nrf2 but not well developed, indicating it deserves further exploration.
    Conclusion: This study revealed field profiles, research hotspots, and future directions of oxidative stress modulator Nrf2 in inflammation and cancer research, and our findings will offer a vigorous roadmap for further studies in this field.

      The COVID-19 pandemic has resulted in an unprecedented amount of medical waste, presenting significant challenges for the safe disposal of hazardous waste. A systematic review of existing research on COVID-19 and medical waste can help address these challenges by providing insights and recommendations for effective management of the massive medical waste generated during the pandemic. This study utilized bibliometric and text mining methods to survey the scientific outcomes related to COVID-19 and medical waste, drawing on data from the Scopus database. The results show that the spatial distribution of medical waste research is unbalanced. Surprisingly, developing countries rather than developed countries lead research in this area. Especially, China, a major contributor to the field, has the highest number of publications and citations, and is also a centre of international cooperation. The main study authors and research institutions are also mainly from China. And the research on medical waste is a multidisciplinary field. Text mining analysis shows that COVID-19 and medical waste research is mainly organized around four themes: (i) medical waste from personal protective equipment; (ii) research on medical waste in Wuhan, China; (iii) threats of medical waste to the environment and (iv) disposal and management of medical waste. This would serve to better understand the current state of medical waste research and to provide some implications for future research.

      Heightened interest in drinking water research in recent decades has been aimed at narrowing the knowledge gaps surrounding water and health in a global pursuit to provide safely managed drinking water services to populations who continue to lack access. This study used bibliometrics and network analysis to produce a global overview of publications and groups that have contributed to research on drinking water and health in low- and lower-middle-income countries (LLMICs). The United States and the United Kingdom, which have historically dominated the field based on the production and impact of scientific literature, remain at the center of international collaborative research partnerships with emerging countries. However, in recent years, the volume of publications produced by India has surpassed that of the United States while Bangladesh is ranked third for the strongest international collaborations. Iran and Pakistan are also emerging as major producers of research, yet publications out of these countries and India remain disproportionately restricted behind paywalls. Contamination, diarrheal disease, and water resources are the themes that characterize the majority of research on water and health. These findings may be used to accelerate equitable, inclusive research in the realm of water and health, thereby enabling gaps in global drinking water inequalities to be filled.

      Sentiment analysis has been researched extensively during the last few years, however, the sentiment analysis of citations in a research article is an unexplored research area. Sentiment analysis of citations can provide new applications in bibliometrics and provide insights for a better understanding of scientific knowledge. Citation count, as it is used today to measure the quality of a paper, does not portray the quality of a scientific article, as the article may be cited to indicate its weakness. So determining the polarity of a citation is an important task to quantify the quality of the cited article and ascertain its impact and ranking. This article presents an approach to determine the polarity of the cited article using term frequency-inverse document frequency and machine learning classifiers. To analyze the influence of an imbalanced dataset, several experiments are performed with and without the synthetic minority oversampling technique (SMOTE) and uni-gram and bi-gram term frequency-inverse document frequency (TF-IDF). Results indicate that the proposed methodology achieves high accuracy of 99.0% with the extra tree classifier when trained on SMOTE oversampled dataset and bi-gram features.

      The objective of this study was to examine the distribution of prestigious speaking roles by gender at gambling studies conferences to better understand the state of gender representation within the field. Keyword searches were conducted in the fall of 2019. A total of 16 conferences that occurred between 2010-2019 and comprising 882 prestigious speaking opportunities were included. Quantitative analysis (i.e., t-tests, chi-squared posthoc tests) was undertaken to evaluate the representation of women speakers and if proportions were the same across genders for speakers. There were significantly less women than men within prestigious speaking roles at gambling studies conferences with only 30.2% of speakers being women (p < .001). This underrepresentation of women was consistent across conference location, speaker continent, speaker role, time, and across the majority of conferences. Women held prestigious speaking roles less frequently than men (M = 1.48 vs. 1.76; p < .001). A 9 to 1 (p < .001) ratio of men to women was found among top 10 most frequent prestigious speakers. While there was a higher proportion of women than men among student speakers and there was no significant gender disparity among early career researchers, there was a significantly lower proportion of women than men among speakers who hold more senior academic positions. There is an issue of gender disparity in prestigious speaking roles at conferences within the gambling studies field. This study highlights the need to counteract gender disparities and make room for diversity within the field.

      Energy has had a definitive impact on human life throughout history. Beginning with the harnessing of fire, which offered warmth, improved shelter and more food, humanity's standard of living has been defined by the power derived from fuels and food. Access to energy is the briefest way in which to summarize the history of the world. Direct and indirect causes of war have involved access to energy, and the results of conflicts have been determined by who controlled the energy resources. Therefore, the scientific literature reveals very close interactions between energy studies and social science studies. The Scopus database contains about 118 000 publications in the fields of social sciences and energy. The current study aims to exploit this resource to identify the interactions that exist between the fields so that future research can investigate these more deeply and thus develop solutions to the problems of the modern world. The present article will analyse these publications systematically according to author, country, institution and year, in addition to examining the changes in keywords that have occurred in these studies over the years. This article is part of the theme issue 'Thermodynamics 2.0: Bridging the natural and social sciences (Part 1)'.

      As a case study of the responses of natural history museums to changing scientific and funding environments, we analysed research publications of Australia's Natural History Museums (ANHMs) 1981-2020. Using Scopus, 9,923 relevant documents 1981-2020 were identified, mainly research papers but with a growing proportion of reviews. The number of documents published increased over tenfold from 39 (1981) to 553 (2020), likely driven by collaborations (rising from 28.5% of documents 1981-1985 to 87.2% of documents 2016-2020), contributions from retired staff, and volunteer support. The mean length of documents (pages) ranged from a low of 15.3 in 2001-2005 to a high of 17.4 in 1991-1995, but this statistically significant result was trivial in practical terms. The sources (i.e., journals, book titles, conference proceedings) in which ANHM authors published changed over time, with growing proportions of publications in journals covering molecular ecology/phylogenetics and biological conservation. We identified the major areas of study canvassed within the corpus of publications by developing structural topic models based on patterns of word use in document titles, abstracts and keyword lists. The topics discovered included study subjects traditional for natural history museums (new taxa, phylogeny, systematics, animal morphology, palaeontology, minerals), new directions (molecular genetics, ecology, biological conservation) and marine biology (probably reflecting Australia's large coastline). Most citations came from Australia, USA and UK, although in 2016-2020 only 27.9% of citing documents included an Australian author. Growth in numbers of documents and collaborations, as well as use of documents internationally over a period of great change in scientific and funding environments, indicate an enduring legacy of ANHM research, grounded on the intrinsic value of the collections.

      This study analyzed the academic accomplishments and demographics of elected presidents of the American Academy of Orthopaedic Surgeons (AAOS), American Orthopaedic Association (AOA), and American Board of Orthopaedic Surgery (ABOS). Curriculum vitae and internet-based resources were reviewed to collect demographics, training characteristics, bibliometrics, and National Institutes of Health (NIH) research funding of contemporary presidents (1990-2020). Eighty presidents were included. Most presidents were men (97%), and 4% of presidents were non-White (3% Black and 1% Hispanic). Few had an additional graduate degree (4% MBA, 3% MS, 1% MPH, 1% PhD). Ten orthopedic surgery residency programs trained 47% of these presidents. Most had fellowship training (59%), and the top three were hand surgery (11%), pediatric orthopedics (11%), and adult reconstruction (10%). Twenty-nine presidents (36%) participated in a traveling fellowship. The mean age at appointment was 58±5 years, which was 27 years since residency graduation. The mean h-index was 36±23, resulting from 150±126 peer-reviewed manuscripts. Orthopedic surgery presidents had more peer-reviewed manuscripts (150±126) than chairs (73±81) and program directors (27±32) (P<.001). AOA presidents had the highest mean h-index (42±21) compared with AAOS (38±27) and ABOS (25±16) presidents (P=.035). Nineteen presidents had NIH funding (24%). More presidents had NIH funding in the AOA (39%) and AAOS (25%) than the ABOS (0%) (P=.007). Orthopedic surgery presidents possess high levels of scholarly output. AOA presidents had the highest h-index values and prevalence of NIH funding. Females and racial minorities remain underrepresented at the highest levels of leadership.

      In recent years, there has been a rapid increase in the number of people with aphasia due to brain lesions worldwide, which has prompted researchers to carry out in-depth studies on the pathogenesis, inducement and prognosis of aphasia from neurology, clinical medicine, psychology and other disciplines. With the deepening of research and understanding of aphasia, it is generally believed that a single discipline can no longer meet the needs of the academic community. Therefore, multidisciplinary integration has emerged and achieved fruitful results. This paper, based on the biblioshiny package run by R, conducts bibliometric analysis on the international interdisciplinary research status of conversation and aphasia, predicts its future development direction, and provides reference for relevant domestic research from international source journals. The results indicate that led by Australia, the United Kingdom, the United States and other countries, the international conversational aphasia research has formed a complete system, and formed a "descriptive study of patients with language disorders" and "applied study of rehabilitation treatment". In the future, while continuing to focus on these two categories of research, the empathy ability of conversational partners and medical staff may be taken into account, in order to better contribute to improving patients' quality of life.

      Background: Reablement is a holistic and multidisciplinary intervention that can facilitate achievement of service users' goals related to their independence in everyday activities. Reablement has been the subject of increasing scientific activity in recent years. Currently, no review has provided a broad overview of the extent and breadth of international publications in reablement.Objective: The objectives were 1) to map the volume of reablement publications, how the publications had increased over time, and their geographical distribution, 2) to identify the publication types and designs, 3) to identify publication trends, and 4) to identify knowledge gaps in the current peer-reviewed literature.
    Methods: The scoping review approach designed by Arksey and O'Malley was used to identify peer-reviewed articles on reablement. Information was obtained on scientific activity on reablement over a period of more than two decades from five electronic databases and without language restrictions. Data was extracted from the eligible articles and both descriptive analysis and thematic analysis of the data was performed.
    Results: A total of 198 articles published from 1999 to August 2022 from 14 countries were identified. There is a continuous interest in the field from countries where reablement has been implemented. An international and historical overview among countries with peer-reviewed publications on reablement is presented, which also partly reflects the countries that have implemented reablement. Most of the research derives from Western countries, in particular from Norway. Varied approaches to publications in reablement were noted with the majority being empirical and quantitative in nature.
    Conclusion: The scoping review confirms the continued expansion of the breadth of reablement-focused publications in terms of originating countries, target populations, and research designs. In addition, the scoping review contributes to the knowledge base regarding reablement's research front.

      OBJECTIVES: To determine the publication rate of mandatory research projects conducted by obstetrics residents and to evaluate the publication-associated factors and reported obstacles.STUDY DESIGN: This retrospective cohort study included all consecutive residents in an academic obstetrics-gynecology department in Paris, France, between 2010 and 2020. All residents were required to conduct a research project. Information about publication was collected by searching PubMed. A closed-ended questions questionnaire was sent to former residents about their characteristics, subsequent professional development, and research project characteristics. Factors associated with publication were identified by univariable and multivariable analysis with logistic regression.
    RESULTS: During the study period, 156 residents trained in our obstetrics-gynecology department. The overall publication rate was 30.8% (48/156) and the median time to publication 27 months (IQR, 18-37). The resident was first author in 36 (75.0%) publications. Among the 130 (83.3%) residents who completed the questionnaire, 43 (33%) had published their research project. Overall, 74/130 (60.8%) residents used their project for their mandatory medical thesis. Factors associated with publication in univariable analysis were younger age (median), completion of a PhD, planned career in academic medicine, prospective study design, presentation at a conference or congress and use their project for their medical thesis. The only factors associated with publication in the multivariable analysis were planned career in academic medicine (aOR 5.62 95 %CI[1.84-17.19]) and the prospective study design of the research project (aOR 6.1 95 %CI[1.24-29.56]). The main reasons for nonpublication reported by resident were lack of time and failure to complete the project.
    CONCLUSION: Among the mandatory clinical research projects conducted by obstetrics residents over a decade in our department, 30.8% were published. The main factors associated with publication were planned career in academic medicine and a prospective design of the research project.

      Despite a spike in publications on business strategies focused on environmental awareness subjects in recent years, business-environment nexus research has recently been criticized for failing to address urgent issues like climate change. Therefore, we endeavored to do a trend analysis to find knowledge gaps in business studies related to the interaction between businesses, the environment, and society using bibliometric. Our study reveals that the area of business sustainability has evolved over the past decade from an internal conquest to include external indices like the environment, such as the debate over the relative merits of social and economic performance and the greening of management. Our findings point to three (3) main conclusions. (1) Many corporations see the urgency of green practices and have distinctive organizational sustainability and business strategies for environmental crises. (2) Business strategy and environment research are concentrated within developed countries to the neglect of developing countries. (3).The literature on business sustainability has not yet given much attention to the managerial implications and effects of climate change. Therefore, scholars must test and develop business-environmental nexuses to aid in sustainable production and consumption improvement.

      Zingiber officinale, Curcuma longa, and Momordica charantia are medicinal plants that are commonly used in the form of herbal tea, which is formulated to strengthen the immune system, especially against COVID-19 infection. Excellent antioxidant, anti-inflammatory, and immunostimulatory properties have been reported for their bioactive compounds, which have been shown to aid in stimulating immune systems as well as lowering the risk of severe COVID-19 such as lung injury. Yet, no bibliometric study on the subject is available. Hence, the purpose of this study is to quantitatively examine the existing articles related to the therapeutic potential of these three herbs, as well as their mechanisms of action in combating the SARS-CoV-2 virus. A total of 121 papers were retrieved from Scopus database up to 14th March 2023. The bibliometric analysis was conducted using VOSviewer software. Based on the literature search, Z. officinale was the most researched plant. India appeared as the most prolific country, with the highest number of articles contributed by two authors from India (Rathi, R. and Gayatri Devi, R.). In terms of keywords, the plants were associated with immune modulation, management of symptoms, antioxidant, anti-inflammatory and antiviral activities. Several important bioactive compounds were responsible for these effects such as gingerol, paradol, shogaol, curcumin, calebin A, momordicoside, karaviloside and cucurbitadienol. These compounds were hypothesized to prevent and cure COVID-19 by regulating inflammatory response, downregulating oxidative stress and modulating immunostimulatory activity. This review paper therefore supports the potential of Z. officinale, C. longa, and M. charantia to be formulated as a herbal blend for treating and preventing COVID-19 infection.

      STEM disciplines are considered essential for human development, and they are associated with low unemployment rates and good economic prospects. However, many countries are faced with the problem of too few STEM graduates, which raises the question of why more students do not choose STEM majors. This study presents a systematic mapping of studies published prior to 2021 in Web of Science or Scopus in order to examine the research trends on the factors that cause students to choose a career in Computer Science, or more generically, in the STEM fields. These factors have been identified and classified in 3 categories: Environmental factors, Social influencers and Personal factors. The categories are made up of 4 levels of subcategories. We analyzed (1) the countries in which the study was conducted, (2) the characteristics of the study and (3) the frameworks used. The results show that the bulk of the studies were conducted in developed countries, mainly in North America and Europe. The frameworks most commonly used in the studies are Expectancy-Value Theory and Social Cognitive Career Theory, and consequently, the most commonly studied factors for STEM degrees are those related to personal psychological factors. For Computer Science degrees, the most frequently studied factor is career prospects. On the other hand, a small number of studies on the impact of social media on the choice of studies in the technology field were detected. Among the studies analyzed, there is great interest in determining the factors that specifically affect women and the differences between men and women, especially in studies dealing with the Computer Sciences. Furthermore, there are few studies that analyze the effect of informal educational experiences among women. Given that this kind of experiences has become very popular in recent years among women, future research should analyze their impact on the choice of STEM studies. Taking into account the current relevance of the social media, additional research on their impact on the choice of studies should be conducted. It would also be necessary to analyze the situation in underdeveloped countries, especially among women, given that this field is currently a driver of economic development.

      Introduction: Research and publications are becoming increasingly important for residents who want to match into competitive fellowship training programs and fellows looking to optimize career opportunities. Institutional Research Days provide trainees the opportunity to gain presentation experience and feedback about their studies. We evaluated all abstracts that were presented at Ascension Providence Hospital (APH) during Research Day over a 10-year period to determine publication rates of manuscripts in peer-reviewed journals.Methods: Research abstracts presented by both residents and fellows during Research Days at APH from 2009 to 2018 were reviewed. Abstracts were classified by type of project, type of presentation, trainee, winners and non-winners, and training program. Winners were defined as abstracts which won first, second and third place awards. Publication of manuscripts was evaluated by searching PubMed and Google Scholar. Fisher's Exact test was used to analyze categorical data and Student's t-test was used to analyze continuous data; p < 0.05 was considered significant.
    Results: A total of 491 research and case report abstracts were presented by residents and fellows during Research Day over 10 years. For residents, 346 abstracts were presented; 25% (n = 85) were winners. The majority (51%) of winning abstracts were published, but only 26% of non-winning abstracts were published (p < 0.0001). More of both winning research oral (65%) and poster abstracts (61%) were published than non-winning oral (41%) and poster abstracts (22%, p = 0.02 and p = 0.0001, respectively), but publication rates for case reports were similar. The vast majority of published winning oral (88%) and poster abstracts (74%) came from the surgical programs. Fellows presented 145 abstracts; 30% (n = 43) were winners. A slightly higher percentage of winning abstracts (42%) were published compared to non-winning abstracts (32%, p = 0.3). Unlike the residents, the fellows had no significant publication rate differences between winning and non-winning research oral, research poster or case report abstracts, or between medical and non-medical subspecialties.
    Conclusions: Despite their award-winning presentations, residents and fellows published less than half of these projects and less than a third of non-award-winning projects. However, most publications came from the surgical specialties, indicating the colleagues in the medical specialties were not publishing. Further data are needed to identify factors that can improve a trainee's chances of being published in a peer-reviewed journal.

      Introduction: Policymakers, researchers, and practitioners have recently begun treating employability-an individual's ability to possess and continuously adjust and acquire up-to-date competencies, flexibility, adaptability, and openness to change-as crucial to enabling employees to respond to ubiquitous and rapid changes in organizations (e.g., changing tasks and work-related processes). Research into ways to enhance employability, particularly through supervisor leadership, which, for example, facilitates training and competence development, has thus grown in popularity. A review on leadership as an antecedent of employability is both evident and timely. This review thus addresses the question of whether a supervisor's leadership influences employees' employability, and in which contexts and through which mechanisms it does so.Methods: As preliminary study we conducted a bibliometric analysis (which corroborated employability's recent rise in popularity) and as main study we conducted a systematic literature review. For this, the authors independently searched for articles, which met the inclusion criteria and subsequently were included for full text analysis. The authors also independently used the forward and backward snowballing technique for identifying additional articles which met the inclusion criteria and subsequently were included for full text analysis. The procedure resulted in 17 articles in total.
    Results: Most of the articles identified positive relationships among several conceptualizations of supervisor leadership and employee employability, such as transformational leadership and leader-member exchange, and to a lesser extent, servant leadership and perceived supervisor support. This review suggests that such relationships occur across different work contexts, such as educational, SMEs, healthcare, and several other industries, and these contexts also vary geographically.
    Discussion: The relationships among supervisor leadership and employee employability are largely explained using a social exchange perspective, which means that the positive influence of leadership on employability is itself influenced by a two-way social exchange relationship between supervisor and employees. The quality of the dyadic relationship between leader and followers thus determines the extent to which leaders offer valuable resources such as training and feedback, which subsequently enhances employees' employability. This review demonstrates that investing in supervisors' leadership is a valuable HRM strategy that fosters employability, and it identifies practical implications that inform policy and practice and sets an agenda for future employability research.
