       BACKGROUND: Behcet's disease (BD) is a systemic vasculitis accompanied by oral-genital ulcers, ocular, cerebral, and gastrointestinal disorders. The aim of this study was to evaluate BD articles published between 2010-2019 bibliometrically and to provide up-to-date data. A secondary aim was to present a different perspective using altmetric assessments.
    METHODS: This bibliometric and altmetric research was performed with data obtained from the Web of Science database. The key terms "Behcet's disease," "Behcet's syndrome," and "Behcet" were used for listing the articles. The number of articles, citation data, and active countries were determined. Trend and correlation analyses were performed. Altmetric attention scores (AASs) and Mendeley readers count (MRC) of the articles were acquired for the altmetric evaluations.
    RESULTS: A total of 5,201 articles were listed. After the exclusion criteria, a total of 2,163 articles were obtained for further analysis. A significant and increasing trend was detected in the number of articles from 2010 to 2019 (P < 0.001). Turkey (28.24%), China (9.57%), South Korea (9.20%), Japan (6.38%), and Italy (5.64%) were the five most productive countries. France, the United States and, the United Kingdom were the top three countries in respect of the average number of citations per article. A weak significant correlation was detected between the number of citations and AAS (P < 0.001). The number of citations was significantly and strongly correlated with the MRC (P < 0.001).
    CONCLUSION: An increasing trend was found in BD research productivity. Although the Silk Road countries were prominent in the number of articles, a similar ranking was not valid for the average number of citations per article.

  2. Arch Osteoporos. 2021 Aug 19. 16(1): 122
      Our aim is to evaluate and compare the most discussed articles on osteoporosis in academia and social media. The treatment of osteoporosis was the most popular topic in the top 100 citation (n = 31) and altmetric lists (n = 47). The general public, as well as academia, is curious about the treatment of osteoporosis.
    PURPOSE: The main aim of this study is to investigate the trends in the field of osteoporosis and guide researchers by conducting bibliometric and altmetric analysis for osteoporosis with the most cited and discussed articles on social media.
    METHODS: The keyword "osteoporosis" was searched from the Web of Science All Databases and Altmetric.com website, and the top 100 (T100) citation and altmetric list was created, respectively. The T100 citation and altmetric list articles were analyzed and compared in terms of study type, topic of study, first author, publication year, citation number, journal quartile in category, impact factor, and Altmetric Attention Score (AAS).
    RESULTS: T100 cited articles: the median for citation number was 1117 (range: 717-3854) and the median for AAS was 9 (range: 0-371). T100 altmetric articles: the AAS median was 158 (range: 93-658) and citation number median was 31 (range: 0-2132). Only 6 articles were the same in both lists. The number of articles about treatment was 31 in the T100 citation list and 47 in the T100 altmetric list. The most ranked journals were "The New England Journal of Medicine" with 22 articles in the T100 citation list and "Osteoporosis International" with 16 articles in the T100 altmetric list.
    CONCLUSION: Unlike the citation number, one of the greatest contributions of AAS to researchers may be developing appropriate policies in the field of osteoporosis according to the interests of the society.

       Objective: To identify and evaluate the indexed studies that allow us to understand the implications of imaging studies in MRI and PET/CT related to COVID-19 research.
    Methods: Scoping review. Articles in PubMed, Scopus, and Web of Science (WoS) were scanned from 2019 to 2021 with COVID-19, MRI, and PET-CT as keywords. EndNote software and manual checking removed the duplicated references. Our assessment includes citation, bibliometric, keyword network, and statistical analyses using descriptive statistics and correlations. Highlighted variables were publication year, country, journals, and authorship.
    Results: Only 326 papers were included. The most cited article reached 669 cites; this number represented 21.71% of 3081 citations. The top-15 cited authors received 1787 citations, which represented 58% of the total cites. These authors had affiliations from ten countries (Belgium, China, France, Italy, Japan, Spain, Sweden, Turkey, United Kingdom (UK), and the USA). The top-30 journals were cited 2762 times, representing 89.65% of the total cites. Only five journals were cited more than 100 times; Int J Infect Dis had the most significant number of citations (674). Some of the unexpected keywords were encephalitis, stroke, microbleeds, myocarditis.
    Conclusion: COVID-19 pandemic is still spreading worldwide, and the knowledge about its different facets continues advancing. MRI and PET/CT are being used in more than 50% of the selected studies; research trends span seven categories, no only the diagnostic but others like socio-economic impact and pathogenesis Developed countries had an advantage by having hospitals with more resources, including MRI and PET/CT facilities in the same institution to supplement basic assessment in patients with COVID-19.

      Many cities worldwide are using re-greening strategies to help reverse urbanization patterns that aggravate environmental issues. Green infrastructure (GI) has become a significant and effective strategy to address environmental problems. To better understand GI, this study uses CiteSpace to analyze 5420 published papers in the field of GI on the Web of Science database from 1990-2020. This bibliometric analysis will help new scholars and researchers to better understand the current status and trends in GI research, as well as identify further research needed in the field. This study evaluated research on GI trends according to publication amounts, keywords, journals, disciplines, countries, institutions, and authors. Results show that, first, GI research has experienced rapid growth since 2014. Second, GI, ecosystem services, and city are the top three keywords related to GI research, with green roof as the keyword with the strongest linkage. Third, Sustainability, Urban Forestry and Urban Greening, and Landscape and Urban Planning are the top three journals publishing GI research. Fourth, the top three disciplines researching GI are environmental science, engineering, and science and technology. Fifth, the USA is the top ranked country in terms of the number of published GI-related papers (1514 papers), followed by China (730 papers) and England (546 papers). Sixth, the US Environmental Protection Agency (84 papers) is the top institution in terms of publications, followed by the Chinese Academy of Science (83 papers) and the Swedish University of Agriculture (66 papers). Finally, D. Haase has the most published articles (29 papers), followed by S. Pauleit (28 papers) and P. Angelstam (26 papers). These findings indicate that GI has developed significantly in the last 30 years, with a high probability for increased growth in the future.

       Background: India plays an important role in global research on gestational diabetes mellitus (GDM), but a bibliometric assessment of this research is lacking.
    Objective: To provide a comprehensive analysis of Indian GDM research during the last 30 years using select bibliometric indicators.
    Methods: The Scopus international database was used to retrieve publication data, using a defined search strategy. The analysis focused on research output of Indian authors and organizations and their collaborations. The qualitative performance was assessed in terms of relative citation index and citations per paper (CPP).
    Results: Overall, 100 countries participated in GDM research producing 13,193 publications during 1990-2019. India ranked ninth in global output (1182 publications, 3.1% share) and CPP of 18.6. Only 21.3% of publications had international collaboration and 9.4% were funded. Of the 235 organizations and 544 authors that participated in India's research on GDM, the top 50 organizations and authors contributed 53.8 and 36.4% to national publication share, respectively. The leading productive organizations were AIIMS, New Delhi, KEMH, Pune and PGIMER, Chandigarh, whereas the most productive authors were S. Kalra, V. Seshiah and C.S. Yajnik. Indian Journal of Endocrinology and Metabolism, Journal of Clinical and Diagnostic Research, Journal of Obstetrics and Gynecology of India and Diabetes Research and Clinical Practice were the most productive journals.
    Conclusions: Indian research on GDM is lagging behind other countries which have a similar disease burden. Increasing national and international collaborations, and active support of national and international funding agencies is urgently required to produce quality research on GDM.

       OBJECTIVE: This study aimed to investigate the global research interest regarding silver diamine fluoride (SDF) in dentistry using a bibliometric approach.
    METHODS: A literature search was conducted in the Web of Science Core Collection database to identify studies related to SDF. Bibliometric data from the selected publications were exported and analysed using the Bibliometrix Biblioshiny R-package software. The type of research and main contents of the publications were summarised. One-way analysis of variance was used to detect the differences in the citation counts of the publications with various types of research. In addition, Google Trends was used to investigate the popularity of the search term "silver diamine fluoride".
    RESULTS: A total of 259 publications were included and analysed. The annual scientific production of SDF studies increased significantly per year in the past five years, and it mainly concerned dental caries. The three main types of research were laboratory/animal study (n=114, 44%), review/guideline (n=56, 22%), and clinical trial (n=44, 17%). The citation count related to the type of research (p<0.01). The citation count of clinical trials was significantly higher than that of laboratory/animal studies (p<0.05). As quantified via data from Google Trends, the search popularity of "silver diamine fluoride" also increased significantly.
    CONCLUSION: Based on the results of bibliometric analysis, global research interest regarding SDF has rapidly increased in recent years.
    CLINICAL SIGNIFICANCE: This paper presents an overview of scientific evidence and impact of SDF use in dentistry. SDF attracts a growing interest globally and there has been a steady increase in scientific research into its use in dental practice.

       BACKGROUND: Pemphigus vulgaris (PV) is a rare autoimmune blistering disease characterized by intraepithelial and mucocutaneous blister formation and erosion. Numerous articles related to PV have been published. However, which articles have a tremendous influence is still unknown, and factors affecting article citation numbers remain unclear. We aimed to visualize the prominent entities using the top 100 most-cited articles on the topic of PV (T100PV), and investigate whether medical subject headings (i.e., MeSH terms) can be used to predict article citations.
    METHODS: By searching the PubMed Central (PMC) database, the T100PV abstracts since 2011 were downloaded. Citation analysis was performed to compare the dominant entities in article topics, authors, and research institutes using social network analysis (SNA) and Kano diagrams. We examined the MeSH prediction power against article citations using correlation coefficients (CCs).
    RESULTS: The most cited article (125 times) was authored by Ellebrecht from the University of Pennsylvania in the US. The most productive countries were Germany (28%) and the US (25%). Most articles were published in J Invest Dermatol (16%) and Br J Dermatol (10%). Kasperkiewicz (Germany) and the Normandie University (France) were the most cited authors and research institutes, respectively. The most frequently occurred MeSH terms were administration and dosage, immunology, and metabolism. MeSH terms were evident in the prediction power on the number of article citations (F = 19.77; P < .001).
    CONCLUSION: A breakthrough was achieved by developing dashboards to display the T100PV. MeSH terms can be used to predict the T100PV citations. These T100PV visualizations can be applied in future studies.

       Background: Rapid growth of the integration of technology and psychotherapeutic interventions has been noted, but no clear quantification of this growth has been done.
    Aims: This bibliometric analysis seeks to quantify the growth, trends, and applications of technology in psychotherapeutic interventions over the last 40 years.
    Methods: Searches were conducted in the Web of Science (WOS) database for all existing technology-psychotherapy-related publications from 1981 to October 2020. Search terms were refined using a systematic screening strategy, based upon Cochrane protocol, generating 52 technology terms. Analyses across 40 years and by decade from 1981 to 2020 were conducted.
    Results: A total of 13,934 peer-reviewed articles were identified. Yearly publication rate has increased from one in 1981 to 1902 by October 2020. The growth rate of publications across decades consistently tripled in size (762.50% from the 1980s to 1990s, 539.71% from the 1990s to 2000s, and 337.24% from the 2000s to 2010s). The author, country, journal, and institution with the most publications were Andersson, G., USA, Journal of Medical Internet Research, and Karolinska Institute, respectively. The most frequent technology search term across all four decades was "internet*." The trends in percentages of peer-reviewed publications within each decade showed: 1) a declining trend for the term "computer," 2) an upward trend for the combined terms, "internet," "online," and "web," 3) and a steady but smaller proportion of publications for other terms ("cell phone," "phone/telephone," "technology," "video," "virtual reality or VR," "apps," "digital," "machine learning," "electronic," "robo," and "telehealth").
    Discussion: The rapid growth and trends identified in technology and psychotherapy publications can inform related policies addressing the role of technology in mental health. Moreover, pattern analyses may provide direction for a standard nomenclature to address terminology usage inconsistencies across the field.

      Corrosion had aroused extensive concern and attention because it was an unavoidable problem for marine equipment and facilities in service. However, the current status and development trend of marine environment corrosion research had seldom been systematically studied. Therefore, it was encouraged to use bibliometrics and information visualization analysis methods to conduct bibliometric analysis of related publications in the field of marine environment corrosion based on HistCite, CiteSpace, and VOSviewer software programs. Compared with the traditional comments of researchers in this field, this research provided a direction for the development of quantitative analysis and visualization of marine environment corrosion on a large scale. The results showed that the overall focus of research in the field of marine environment corrosion continued to increase from 1900 to 2019. China had the highest publication productivity, the USA had the highest h-index value and the second highest average citations per item value, Materials Science was the most popular subject category, Corrosion Science was the main journal and Melchers RE was the author with the most output contributions. This research also exhibited four hot spots in this field. In addition, this work could help new researchers to find research directions and identify research trends and frontiers in the field of marine environment corrosion by tracing the research hotspots of topic categories, countries, institutions, journals, authors, and publications in recent years.

       Objectives: Review abstracts presented at the Combined Otolaryngology Society Meeting (COSM) to determine subsequent publication and identify abstract features predictive of publication in high impact journals.
    Methods: A selection of abstracts accepted in the 2015 COSM scientific programs were retrospectively reviewed. MEDLINE searches via PubMed and Google Scholar were performed to determine publication rates. The Journal of Citation Reports was used to determine impact factors for published abstracts. Binomial regression analyses were used to identify factors related to publication in high impact journals.
    Results: 62.4% of reviewed abstracts (n = 623) were subsequently published, with a mean publication time of 14 ± 12 months. Abstract features predictive of publication were basic science type, other science type, prospective studies, multi-institutional involvement, and presentation at the American Laryngologic Association and American Otologic Society meetings. Based on Wald score, podium presentation was found to have the biggest effect on publication. Factors positively associated with publication in high impact (impact factor > 2.272) journals were increased author number and sample size.
    Conclusions: Overall publication rate of abstracts selected for presentation at COSM in 2015 was on the higher end of previously reported otolaryngology meetings. Abstracts detailing basic science, other science, prospective and multi-institutional studies were more likely to lead to future publication. Additionally, increased number of authors and sample size lead to publication in higher impact journals.

       AIM: To analyze the intellectual structure and recent research trends in diabetic retinopathy (DR) and unearth potential knowledge.
    METHODS: English DR publication included in this study was exported from the Web of Science Core Collection, and Chinese DR publication was exported from China National Knowledge Infrastructure from the establishment time of the database to 2019. CiteSpace and Microsoft Excel were used to visually analyze DR research, including analysis of the number of publications, highly cited publication analysis, spatial distribution analysis, and keyword co-occurrence analysis.
    RESULTS: A total of 23 795 English studies and 11 577 Chinese studies, including 2089 studies related to traditional Chinese medicine (TCM), were obtained. The data suggested the following: 1) The number of English and Chinese DR publications increased over time, and the growth rate of English publications was relatively fast. 2) The distribution of international scholars and institutions was close, while the distribution was scattered in China. Shanghai Jiao Tong University has the largest number of publications. Tien-Yin Wong was the core author with the largest number of publications. England and the United States are the core of international DR research cooperation. 3) Optical coherence tomography and risk factors are recent international research hot spots and trends. The difference is that TCM is a recent research trend under DR in China.
    CONCLUSION: DR has drawn an increasing amount of attention worldwide. The focus of research in this field has shifted from tertiary type DR treatment to secondary prevention strategies which focus on the screening and monitoring of disease progression. The advantages of TCM in the prevention of DR have attracted attention, and it is worth incorporating this with Western medicine to address this challenge.

       OBJECTIVES: The purpose of this study is to compare the number of citations received by open access articles versus subscription access articles in subscription journals in the Otolaryngology literature.
    METHODS: Using the Dimensions research database, we examined articles indexed to PubMed with at least 5 citations published in 2018. Articles were included from Otolaryngology-Head and Neck Surgery, The Laryngoscope, JAMA Otolaryngology-Head and Neck Surgery, Annals of Otology, Rhinology, and Laryngology, and American Journal of Otolaryngology. Multivariate Poisson regression modeling was used to adjust for journal, article type, and topic. Practice guidelines, position statements, or retractions were excluded as potential outliers.
    RESULTS: 137 open access articles and 337 subscription access articles meeting inclusion criteria were identified, with a median citation number of 8 (IQR 6-11). The most common article type was original investigation (82.5%), and the most common study topic was head and neck (28.9%). Open access articles had a higher median number of citations at 9 (IQR 6-13) when compared to subscription access articles at 7 (IQR 6-10) (P = .032). Open access status was significantly associated with a higher number of citations than subscription access articles when adjusting for journal, article type, and topic (β = .272, CI 0.194-0.500, P < .001).
    CONCLUSIONS: Although comprising a minority of articles examined in this study of subscription journals, open access articles were associated with a higher number of citations than subscription access articles. Open access publishing may facilitate the spread of novel findings in Otolaryngology.

       BACKGROUND: There are various treatments for facial nerve palsy, and research into this topic is ongoing. In the present study, we carried out bibliometric and visualized analyses to identify the trends of research into facial nerve palsy treatment.
    METHODS: To identify articles, the SCOPUS database was searched for articles published from its inception to December 27, 2020. The search was conducted twice, with Search 1 investigating general treatment trends and Search 2 narrowing the scope to complementary and alternative treatment. The extracted keywords were analyzed using the Visualization Of Similarities (VOS) viewer. Through analysis of keywords, research hotspots in the treatment of facial nerve palsy were identified.
    RESULTS: A total of 1609 and 223 articles were identified in Searches 1 and 2, respectively. The number of articles published each year showed a tendency to increase, and most of the studies were only conducted in a few countries. In terms of subject area, "medicine" was overwhelmingly the most common(77.6%). Based on the analysis of 316 keywords in Search1, "medication treatment," and "complementary and alternative treatment" were the hotspots of research.
    CONCLUSION: This study provides the overall trends of facial nerve palsy treatment. To date, research on medication treatment has been main focus, and antiviral use among medication treatment and complementary and alternative treatment has emerged in recent years.

  16. J Pediatr Surg. 2021 Aug 01. pii: S0022-3468(21)00532-7. [Epub ahead of print]
       BACKGROUND: The publication record can be regarded as a key metric of the academic output of a craft surgical speciality with an almost exponential increase in the number of such publications worldwide over the past 20 years (Ashfaq et al. J Surg Res 2018;229:10-11). We aimed to examine and explore if this was the experience within UK paediatric surgery centres.
    METHODS: The academic search engine Scopus™ (Elsevier) was used to track every paediatric surgeon's (NHS or University) publication history between Jan. 2005 - Dec. 2020. This was validated by an algorithmic search of PubMed™. The h-index (citations/publication), considered a validated metric of career academic output, was also calculated for each individual surgeon. A Field-Weighted Citation Index (Scopus™) (FWCI) was used to assess impact of individual publications. Textbooks, book chapters, abstracts, duplications ("double dipping") and output attributed to UK BAPS-CASS national studies were excluded. Some output(s), not considered as relevant to "paediatric surgery", was edited. Data are quoted as median(range).
    RESULTS: During this 16-year period, there were 3838 publications identified from 26 centres with a "top ten" listing of those paediatric surgical units contributing over half the output (n = 2189, 57%). To look for evidence of trend(s) we analysed the output from these surgical centres in two 5-year periods (2005-9 and 2015-19) and showed an overall fall in output(s) - [730 (53.4%) to 645 (46.4%)] with 6/10 (60%) ' top ten ' centres here recording a reduction in publications. The median h-index of the 232 contributing paediatric surgical consultants was 12 (range 1-56). The best performing publication from the "top ten" centres had 96.5(51-442) citations with the FWCI being 4.5 (2.2 - 30.2).
    CONCLUSIONS: This study highlights current paediatric surgery publication output metrics in UK centres. There is evidence of a relative reduction in outputs overall which is a cause for concern for the future, although individual publications from the 10 most active units in the UK remain highly cited. These findings may serve purpose in several ways: (i) UK paediatric surgical centre rankings may be helpful for guiding residency / trainee application; (ii) surgical research funding for the top performing units may be better facilitated and finally (iii) UK centres showing a ' fertile ground ' for nurturing and training paediatric surgeons with academic aspirations could be useful for future workforce planning.

       Importance: The reporting of race provides transparency to the representativeness of data and helps inform health care disparities. The International Committee of Medical Journal Editors (ICMJE) developed recommendations to promote quality reporting of race; however, the frequency of reporting continues to be low among most medical journals.
    Objective: To assess the frequency as well as quality of race reporting among publications from high-ranking broad-focused surgical research journals.
    Design, Setting, and Participants: A literature review and bibliometric analysis was performed examining all human-based primary research articles published in 2019 from 7 surgical journals: JAMA Surgery, Journal of the American College of Surgeons, Annals of Surgery, Surgery, American Journal of Surgery, Journal of Surgical Research, and Journal of Surgical Education. The 5 journals that stated they follow the ICMJE recommendations were analyzed against the 2 journals that did not explicitly claim adherence.
    Main Outcomes and Measures: Measured study outcomes included race reporting frequency and use of the ICMJE recommendations for quality reporting of race.
    Results: A total of 2485 publications were included in the study. The mean (SD) frequency of reporting of race and ethnicity in publications of ICMJE vs non-ICMJE journals was 32.8% (8.4) and 32.0% (20.9), respectively (P = .72). Adherence to ICMJE recommendations for reporting race was more frequent in ICMJE journals than non-ICMJE journals (mean [SD] of 73.1% [17.8] vs 37.0% [10.2]; P < .001).
    Conclusions and Relevance: The frequency of race and ethnicity reporting among surgical journals is low. A journal's statement of adherence to ICMJE recommendations did not affect the frequency of race and ethnicity reporting; however, there was an increase in the use of ICMJE quality metrics. These findings suggest the need for increased and more standardized reporting of racial and ethnic demographic data among surgical journals.

      Currently, research on intestinal diseases is mainly based on animal models and cell lines in monolayers. However, these models have drawbacks that limit scientific advances in this field. Three-dimensional (3D) culture systems named organoids are emerging as a reliable research tool for recapitulating the human intestinal epithelium and represent a unique platform for patient-specific drug testing. Intestinal organoids (IOs) are crypt-villus structures that can be derived from adult intestinal stem cells (ISCs), embryonic stem cells (ESCs), or induced pluripotent stem cells (iPSCs) and have the potential to serve as a platform for individualized medicine and research. However, this emerging field has not been bibliometric summarized to date. Here, we performed a bibliometric analysis of the Web of Science Core Collection (WoSCC) database to evaluate 5,379 publications concerning the use of organoids; the studies were divided into four clusters associated with the current situation and future directions for the application of IOs. Based on the results of our bibliometric analysis of IO applications, we systematically summarized the latest advances and analyzed the limitations and prospects.

       Aim: Analysing Level of Evidence (LOE) provides an insight to evidence-based medicine (EBM). The aim of our study was to evaluate and analyse trends in Levels of Evidence (LOE) in Journal of Maxillofacial and Oral Surgery (MAOS) since inception, i.e. December 2009 along with categorization into subtopics.
    Methodology: LOE for each article was determined according to modified American Society of Plastic Surgeons (ASPS) scale and National Health and Medical Research Council (NHMRC) Evidence Hierarchy.
    Results: A total of 1264 articles were included in the final analysis, out of which high-quality evidence (Level A) accounted for 7% of the journal. The percentage of Level I/II (Level A) has increased from 2.09% in 2009/2010 to 12.74% in 2019/2020, representing a promising trend toward higher-quality research in just 10 years. Case reports and narrative reviews with Level of Evidence value "D" account the highest number (36%) of all the published articles. The majority of articles fell under Class 2 (Maxillofacial pathology) classification (35%) highlighting myriad of articles covering pathologies and various reconstruction methods, followed by trauma (16%).
    Conclusion: The status of LOE and categorizing of published articles are the first step to audit and quantify the nature of literature published by JMOS and may further help in refining the quality of research jointly by the researchers and the editorial board.

      Superabsorbent polymer (SAP) is a kind of functional macromolecule with super-high water absorption and retention properties, which attracts extensive research and has wide application, especially in the areas of hygiene and agriculture. With reference to the Web of Science database, the SAP research literature from 2000 to 2019 is reviewed both quantitatively and qualitatively. By examining research hotspots, top research clusters, the most influential works, the representative frontier literature, and key emerging research trends, a visual panorama of the continuously and significantly increasing SAP research over the past 2 decades was presented, and issues behind the sharp increase in the literature were discovered. The findings are as follows. The top ten keywords/hotspots headed by hydrogel highlight the academic attention on SAP properties and composites. The top ten research themes headed by clay-based composites which boast the longest duration and the strongest impact have revealed the academic preference for application rather than theoretical study. Academically influential scholars and research studies have been acknowledged, and the Wu group was at the forefront of the research; however, more statistically significant works have been less detected in the last 10 years despite the sharper increase in publications. Hydrogel, internal curing, and aerogel are both current advances and future directions.

       BACKGROUND: The spoken language may influence the way we produce our voice. Therefore, speak more than one language could affect voice production. However, there is limited evidence on the relationship between voice production and bilingualism.
    AIM: To characterize the relationship between bilingualism and voice production determined by means of voice acoustic parameters and voice perception.
    METHODS: A review of literature was performed using four computerized databases. The keywords used were voice, bilingualism, and multilingualism. Relevant data were extracted from the publications on country and year of study, participants, sample size, characterization of voice production (acoustics, perceptual), and languages. A bibliometric analysis was performed for co-occurrence analysis. Quality assessment was conducted with the EPHPP tool.
    RESULTS: A total of 10 publications met our inclusion criteria. Nine of the articles compared English productions with another language. Included studies reported changes in fundamental frequency between English and Spanish, Cantonese Chinese, Mandarin, Russian, Finnish, Arabic, Korean, Welsh, and Hebrew. The co-occurrence analysis shows that fundamental frequency is the most reported parameter, and English is the most compared language among studies including bilingual speakers.
    CONCLUSION: Speaking a second language influences voice production determined by voice acoustic parameters, such as fundamental frequency. Therefore, language may be an important factor to take into consideration when planning assessment and intervention programs on the field of voice.

       OBJECTIVE: The present study aimed to give an overview of research publications on health system preparedness against viral infectious disease outbreaks.
    METHODS: A bibliometric method was implemented from 2001 to 2020. The studied pathogens were dengue, Ebola, influenza, Zika, Middle East respiratory syndrome (MERS), Severe acute respiratory syndrome (SARS), and coronavirus disease 2019 (COVID-19).
    RESULTS: The search query returned 501 documents. The growth of publications showed a sharp peak in 2020 for COVID-19 and 3 small peaks in 2006, 2009, and 2015 for SARS, influenza, and Ebola, respectively. Of the retrieved documents, 208 (41.5%) were on influenza, 164 (32.7%) were on COVID-19, and 83 (16.6%) were on Ebola. Countries in the region of the Americas (n = 221; 44.1%) returned the majority of the documents, while countries in Latin America and the African region returned the least. The United States (n = 197; 39.3%) had a leading role in this field. The US Centers for Disease Control and Prevention (n = 51; 10.2%) ranked first, followed by the Johns Hopkins University (n = 16; 3.2%). The Disaster Medicine and Public Health Preparedness journal (n = 21; 4.2%) ranked first. International research collaboration was relatively inadequate.
    CONCLUSIONS: Research on preparedness against infectious diseases was episodic. Research collaboration needs to be prioritized for countries with a history of fatal outbreaks.

      Social interactions accompany individuals throughout their whole lives. When examining the underlying mechanisms of social processes, dynamics of synchrony, coordination or attunement emerge between individuals at multiple levels. To identify the impactful publications that studied such mechanisms and establishing the trends that dynamically originated the available literature, the current study adopted a scientometric approach. A sample of 543 documents dated from 1971 to 2021 was derived from Scopus. Subsequently, a document co-citation analysis was conducted on 29,183 cited references to examine the patterns of co-citation among the documents. The resulting network consisted of 1,759 documents connected to each other by 5,011 links. Within the network, five major clusters were identified. The analysis of the content of the three major clusters-namely, "Behavioral synchrony," "Towards bio-behavioral synchrony," and "Neural attunement"-suggests an interest in studying attunement in social interactions at multiple levels of analysis, from behavioral to neural, by passing through the level of physiological coordination. Furthermore, although initial studies on synchrony focused mostly on parent-child interactions, new hyperscanning paradigms are allowing researchers to explore the role of biobehavioral synchrony in all social processes in a real-time and ecological fashion. Future potential pathways of research were also discussed.

       PURPOSE: To investigate the characteristics of first-year ophthalmology residents associated with high research productivity in twelve years.
    METHODS: All first-year ophthalmology residents in the United States (US) in 2009 listed by institutional websites were identified. Publications were obtained from Scopus and Google Scholar, h-indices were calculated, and medical school characteristics such as research productivity, region, rank, and average USMLE Steps 1 and 2 scores were obtained from National Institutes of Health, US Census Bureau, and US News.
    RESULTS: Data were obtained on 70% (316/453) of residents; most were male, had Doctor of Medicine (MD) degrees, and graduated from medical schools in the US or Canada. Having an additional graduate degree [OR: 3.05, 95% CI: 1.07-8.67], between 1 and 3 publications [OR: 4.16, 95% CI: 2.22-7.79], or 4 or more publications [OR: 14.27, 95% CI: 3.13-64.94] were associated with higher future research productivity.
    CONCLUSION: Graduate degrees and publication count were key predictors of future research productivity among ophthalmology residents in the US.

       PURPOSE: The objective of this study was to identify the highly cited references that drove the research on implant dentistry with CBCT.
    MATERIALS AND METHODS: The literature database Web of Science Core Collection was accessed to identify a collection of papers on this theme. Cited reference analysis was conducted with the aid of CRExplorer, dedicated bibliometric software.
    RESULTS: The analysis succeeded in identifying the papers that introduced the very first CBCT machines in the Asian and European markets, respectively; papers that proved the CBCT measurement accuracy, its ability to visualize sinus floor penetration, and its reduced metal artifact relative to conventional CT; papers that gave imaging guidelines for implant cases; and papers reporting bone remodeling at extraction sockets and the possibility of grafting at sites with inadequate bone.
    CONCLUSION: These publications together provided solid evidence to support subsequent dental implant research and evaluation by CBCT.

       Background: Ferroptosis is a type of cell death with major topic of debate under current research and plays an important role in disease regulation.
    Objective: In this study, the literature management software Bibexcel and knowledge graph tool VOSviewer were used to summarize and analyze the international research trends and hotspots about ferroptosis in recent years, which highlight the disease mechanism, diagnosis, and treatment related to ferroptosis. Material/Methods. The core collection database of Web of Science was used for retrieving ferroptosis research literature. The information such as the amount of text, the country, the period, the institution, the fund, and the keywords was extracted by the bibliometric tool Bibexcel. The cooccurrence and clustering function of VOSviewer were used to analyze the high-frequency keywords and the cooperative network of the author, institution, and country.
    Results: The research of ferroptosis started late and was formally proposed in 2012. It has developed rapidly and presented an "exponential" growth trend. China, the United States, Germany, Japan, and France are the main national forces of ferroptosis research development. The United States and China have a relatively high degree of support and attention to ferroptosis. Exploring oxidative stress, inducers/inhibitors, synergistic antitumor effect, relationships with other cell death types, GSH/GPX4 and iron metabolism imbalance related mechanisms of ferroptosis, and ferroptosis in the nervous system disease, ischemia-reperfusion injury, tumor, inflammation, and age-related diseases are the hot research directions.
    Conclusion: Ferroptosis has been a research hotspot in the field of biomedicine in recent years and has attracted the attention of scholars all over the world. The occurrence mechanism of ferroptosis and its application in neurological diseases, ischemia and reperfusion injury, tumors, inflammation, and aging are the hot directions of current research. In the future, ferroptosis can be appropriately considered for strengthening new approaches, new diseases, new inductors, new inhibitors, clinical transformation, and traditional medicine research.

      Advances in bibliometrics and co-citation analysis provide the opportunity to analyze quantitatively the large amount of nursing research used in evidence-based nursing. Numerous nursing researchers have attempted to obtain evidence that using evidence-based nursing improves the quality of nursing practices. However, little is known about how these efforts comply with the rigorous methods required for a systematic review in a subject area. This study explored the comprehensiveness of systematic reviews in four guidelines for preventing inpatient falls using bibliometrics and a co-citation network technique. Citations (n = 659) and 9417 unique bibliographic records written by 6537 authors were collected from the guidelines in January 2020. The results showed none of the references spanned all four authoring bodies, whereas only 0.1% and 4.7% of the references spanned three and two of the authoring bodies, respectively. The co-citation analysis revealed differences in the scope and primary concerns among the development groups, even in the same setting, with differences in the highly influential articles and authors. These findings imply that although the systematic reviews of guidelines on fall prevention were of good quality, there remain areas for improvement in terms of harmonizing the selection of bibliographic citations comprehensively.

      Antineoplastic agents present potential hazards to human health and the environment. For this reason, these compounds have attracted a great deal of attention from researchers in the environmental sciences field. In order to help guide future research, it is important to understand the current state of investigation of the occurrence of these microcontaminants and methods for their removal, especially focusing on Fenton and photo-Fenton processes applied to various aqueous matrices in which this class of pharmaceuticals is present. For this purpose, a systematic review of these topics was performed by bibliometric analysis of articles published during the last decade and available in the Scopus and Web of Science databases. This study enables visualization of the current panorama and trends in this field, providing a guide for future collaborative research and exchange of knowledge. Various strategies have been suggested to improve the efficiency of Fenton and photo-Fenton processes, mainly by means of the application of multiples additions of iron, the use of heterogeneous catalysts, and/or the use of chelating agents. Some studies have evaluated different radiation sources employed for photo-Fenton processes, such as solar and/or artificial radiation. In turn, the identification of transformation products generated by Fenton and photo-Fenton treatments, together with their evaluation by in silico (Q)SAR predictions or experimental toxicological bioassays, are related subjects that have been less reported in published works and that should be studied in depth. These subjects can support treatment evaluations that are more realistic, considering their limitations or potentials.

       OBJECTIVE: To elucidate financial and intellectual conflicts of interest (COIs) among clinical practice guideline (CPG) authors of allergic rhinitis in Japan and to evaluate the extent of transparency and accuracy in COIs by CPG authors of allergic rhinitis.
    STUDY DESIGN: A cross-sectional analysis of the payment data from all 79 pharmaceutical companies in Japan between 2016 and 2017.
    SETTING: Japan.
    METHODS: We considered all 27 CPG authors from 2 different versions of the most prominent CPGs for allergic rhinitis in Japan. Using payment data disclosed by 79 major pharmaceutical companies between 2016 and 2017, we assessed the magnitude and characteristics of financial COIs of CPG authors. We also evaluated the intellectual COIs of the CPG authors by counting self-citations of research articles related to CPG statements and recommendations.
    RESULTS: Of 27 CPG authors, 26 authors (96.3%) received at least 1 payment from a combined total of $1,333,552 between 2016 and 2017. The 2-year combined average and median monetary values per author were $49,391 (SD, $67,438) and $18,400 (interquartile range: $6,216-$72,494), respectively. Pharmaceutical companies with novel drugs predominantly made these payments. The percentage of citations with at least 1 CPG author relative to total citations was 47.6% in 2016 and 27.9% in 2020. There were no formal COI disclosure statements in either version.
    CONCLUSION: This study found that allergic rhinitis CPG authors had significant financial relationships with pharmaceutical companies, particularly those marketing novel drugs. In addition, CPG authors had relatively high self-citation rates, a potential marker of intellectual COIs. More rigorous and comprehensive COI management strategies are needed.

       BACKGROUND: There is increasing concern regarding the attrition of surgeon-scientists in cardiothoracic (CT) surgery. However, the characteristics of CT surgeons who are actively leading basic science research (BSR) have not been examined. We hypothesized that early exposure to BSR during training and active grant funding are important factors that facilitate the pursuit of BSR among practicing CT surgeons.
    MATERIALS AND METHODS: We created a database of 992 CT surgeons listed as faculty at accredited United States CT surgery teaching hospitals in 2018. Data regarding each surgeon's training/professional history, publication record, and National Institutes of Health funding were acquired from publicly available online sources. Surgeons who published at least one first- or last-author paper in 2017-2018 were considered to be active, lead researchers.
    RESULTS: Of the 992 CT surgeons, 73 (7.4%) were actively leading BSR, and 599 (60.4%) were actively leading only non-BSR. Only 2 women were actively leading BSR. Surgeons actively leading BSR were more likely to have earned a PhD degree (20.5% versus 9.7%, P = 0.0049), and more likely to have published a first-author BSR paper during training (76.7% versus 40.9%, P< 0.0001). Surgeons actively leading BSR were also more likely to have an active National Institutes of Health grant (34.2% versus 5.8%, P< 0.0001), especially an R01 grant (21.9% versus 2.5%, P< 0.0001).
    CONCLUSIONS: A small minority of CT surgeons at academic training hospitals are actively leading BSR. In order to facilitate the development of surgeon-scientists, additional support must be given to trainees and junior faculty, especially women, to enable early engagement in BSR.

       BACKGROUND: Women have long been underrepresented in orthopaedic surgery; however, there is a lack of quantitative data on the representation of women in orthopaedic academic program leadership.
    QUESTIONS/PURPOSES: (1) What is the proportion of women in leadership roles in orthopaedic surgery departments and residency programs in the United States (specifically, chairs, vice chairs, program directors, assistant program directors, and subspecialty division chiefs)? (2) How do women and men leaders compare in terms of years in position in those roles, years in practice, academic rank, research productivity as represented by publications, and subspecialty breakdown? (3) Is there a difference between men and women in the chair or program director role in terms of whether they are working in that role at institutions where they attended medical school or completed their residency or fellowship?
    METHODS: We identified 161 academic orthopaedic residency programs from the Accreditation Council for Graduate Medical Education (ACGME) website. Data (gender, length of time in position, length of time in practice, professorship appointment, research productivity as indirectly measured via PubMed publications, and subspecialty) were collected for chairs, vice chairs, program directors, assistant program directors, and subspecialty division chiefs in July 2020 to control for changes in leadership. Information not provided by the ACGME and PubMed was found using orthopaedic program websites and the specific leader's curriculum vitae. Complete data were obtained for chairs and program directors, but there were missing data points for vice chairs, assistant program directors, and division chiefs. All statistical analysis was performed using SPSS using independent t-tests for continuous variables and the Pearson chi-square test for categorical variables, with p < 0.05 considered significant.
    RESULTS: Three percent (4 of 153) of chairs, 8% (5 of 61) of vice chairs, 11% (18 of 161) of program directors, 27% (20 of 75) of assistant program directors, and 9% (45 of 514) of division chiefs were women. There were varying degrees of missing data points for vice chairs, assistant program directors, and division chiefs as not all programs reported or have those positions. Women chairs had fewer years in their position than men (2 ± 1 versus 9 ± 7 [95% confidence interval -9.3 to -5.9]; p < 0.001). Women vice chairs more commonly specialized in hand or tumor compared with men (40% [2 of 5] and 40% [2 of 5] versus 11% [6 of 56] and 4% [2 of 56], respectively; X2(9) = 16; p = 0.04). Women program directors more commonly specialized in tumor or hand compared with men (33% [6 of 18] and 17% [3 of 18] versus 6% [9 of 143] and 11% [16 of 143], respectively; X2(9) = 20; p = 0.02). Women assistant program directors had fewer years in practice (9 ± 4 years versus 14 ± 11 years [95% CI -10.5 to 1.6]; p = 0.045) and fewer publications (11 ± 7 versus 30 ± 48 [95% CI -32.9 to -5.8]; p = 0.01) than men. Women division chiefs had fewer years in practice and publications than men and were most prevalent in tumor and pediatrics (21% [10 of 48] and 16% [9 of 55], respectively) and least prevalent in spine and adult reconstruction (2% [1 of 60] and 1% [1 of 70], respectively) (X2(9) = 26; p = 0.001). Women program directors were more likely than men to stay at the same institution they studied at for medical school (39% [7 of 18] versus 14% [20 of 143]; odds ratio 3.9 [95% CI 1.4 to 11.3]; p = 0.02) and trained at for residency (61% [11 of 18] versus 42% [60 of 143]; OR 2.2 [95% CI 0.8 to 5.9]; p = 0.01).
    CONCLUSION: The higher percentage of women in junior leadership positions in orthopaedic surgery, with the data available, is a promising finding. Hand, tumor, and pediatrics appear to be orthopaedic subspecialties with a higher percentage of women. However, more improvement is needed to achieve gender parity in orthopaedics overall, and more information is needed in terms of publicly available information on gender representation in orthopaedic leadership.
    CLINICAL RELEVANCE: Proportional representation of women in orthopaedics is essential for quality musculoskeletal care, and proportional representation in leadership may help encourage women to apply to the specialty. Our findings suggest movement in an improving direction in this regard, though more progress is needed.

      Heavy metals and metalloids (HMMs) pose a serious threat to both environmental and human health. The unique characteristics and environmental toxicity of HMMs make their removal from the environment a major challenge. Constructed wetlands (CWs) are increasingly being used as an eco-friendly system for the removal of HMMs from aqueous environments. In this review, bibliometric analysis was performed using the Scopus database using VOSviewer software to assess the developing use of CWs in recent years. Heavy metal and metalloid (HMM) removal pathways were reviewed (such as precipitation, co-precipitation, adsorption and ion exchange, plant action and microbial action) along with the impact of key factors (pH, chemical oxygen demand, dissolved oxygen, HMM concentration, and temperature). This review aimed to establish the connections between published results, to help effectively optimize the use of CWs for the removal of HMMs and identify the most critical factors for their effective removal. Important aspects that require further research include assessing the synergistic toxicity between different pollutants and combining the use of CWs with other technologies to optimize pollutant remediation efficiency.

      Social media (SoMe) refers to a variety of virtual platforms used to enhance sharing of information. To evaluate the influence of SoMe with regards to views and downloads of published dermatology articles, we conducted a retrospective study from July 2020-March 2021 examining articles published on Instagram and Twitter under Dermatology Online Journal (DOJ) accounts and compared these with type-matched and issue-matched articles that were not posted on social media. During this time period, 163 total articles of the three types used for social media (Case Report, Case Presentation, and Photo Vignette) were published in DOJ and 15 were promoted via SoMe. Utilization of SoMe demonstrated a significant (P<0.0001) positive effect with regards to both views (175.5±16.4) and downloads (31.5±4.0) over matched articles not published on SoMe. Similar trends illustrating the positive effect of SoMe on readership have been previously observed in the field of dermatology as well as other medical specialties. Most direct accessions to articles arrived via Instagram rather than Twitter, diverging from previous studies on SoMe use in medical journals. Social media, in particular Instagram, can be a successful platform to enhance the exposure of peer-reviewed medical information.
