REVISTA BRASILEIRA DE MEDICINA DO ESPORTE: 10 ANOS DE INDEXAÇÃO NA WEB OF SCIENCE

ABSTRACT Analyses of scientific production have attracted the interest of researchers, as they help to control the quality of what is published, identify relevant themes, and, thus enable scientific advances. Therefore, the objective of this study was to analyze the scientific production of the Brazilian Journal of Sports Medicine on the Web of Science database through a bibliometric analysis. The data were analyzed in relation to the publications, the authors, and the RBME. During the period of indexation on the Web of Science, which corresponds to the last decade, the RBME published 896 documents, most of which were original articles (801, 89.3%). The most cited keywords were exercise (117 studies), resistance training (37), and physical activity (34). Brazilian institutions had the highest number of publications, followed by Portugal and Spain, and there were also articles published in the USA, Canada, and the United Kingdom. USP and UNESP were the institutions with the greatest number of publications in the RBME over the last decade. Ten different collaboration clusters were identified, with researcher Edilson Serpeloni Cyrino standing out with the largest collaboration network. The ten years of indexation on the Web of Science reveal the consolidation of the RBME on the international scene, which has resulted in increasing views of and citations from the studies published, as well as attracting researchers from institutions of other countries to publish their work.

The 100 Most Cited Articles in Endoscopic Endonasal Skull Base Surgery: A Bibliometric Analysis

The accelerated growth of endoscopic endonasal skull base surgery has led to an abundance of highly cited works that have helped shape the field into its current state. Highlighting these works can serve as a guide for trainees and facilitate evidence-based clinical decision making and operative techniques. Elsevier's Scopus database was used to generate a list of the 100 most cited articles on endoscopic endonasal skull base surgery in September 2022. Results were categorized based on pathology, approach, study design, and study objective. A citation per year analysis was conducted to highlight later publications that may not have had the time to accumulate as many citations as older publications. The average number of citations for the 100 most cited articles was 210 per article (range 104-1285). Publication dates ranged from 1997 to 2019, with the highest number of articles among the 100 most cited being published in 2008 (15 articles). The journal with the greatest number of publications was Neurosurgery (30 articles). Of the 100 most cited articles, 77 were published between 2000 and 2010. Moreover, 40 of the 100 articles reported surgical outcomes and related complications, and the most common pathology was pituitary adenoma (25 articles). This article provides a list of highly influential articles in the field of endoscopic endonasal skull base surgery, highlighting its rapid evolution over the last 3decades and demonstrating its leap from small descriptive series confined to certain pathologies to larger cohorts exploring possible boundaries and other pathologies.

A bibliometric analysis of global trends in the research field of pharmaceutical care over the past 20 years.

Pharmaceutical care is essential in building up the basics of public health and clinical care. A comprehensive understanding of global status in the field of pharmaceutical care is necessary for directing its research frontiers and future trends. Therefore, this study aims to make a bibliometric analysis to track the development of pharmaceutical care research worldwide during the past two decades. The publications regarding pharmaceutical care were culled from the Web of Science Core Collection (WoSCC). Countries, institutions, authors, journals, references, and keywords in this field were visually analyzed by using VOSviewer (version 1.6.17) and CiteSpace (Version 5.8.R3). As a result, 3,597 publications (3,177 articles and 420 reviews) were obtained. The annual yields grew more than three times in the past two decades, from 54 records in 2002 to 379 papers in 2021. The United States played the leading role in this research from multiple aspects, including publication (n = 1,208), citations (n = 28,759), funding agencies, and collaboration worldwide. The University of Sydney in Australia was the most contributed institution with the greatest number of publications (n = 112) in pharmaceutical care research. Hersberger KE from the University of Basel was the most productive author (n = 40). Chen TF from the University of Sydney was the author who owed the highest H-index of 19 and most citations (n = 1,501). They both significantly impacted this field. American Journal of Health System Pharmacy produced the most publications, while Pharmacotherapy had the highest IF (IF2020 = 4.705) in this field. Clusters networks of co-cited references and keywords suggested that clinical pharmacy is an essential theme in pharmaceutical care. Terms of medication safety and critical care recognized by burst analysis of keywords also hint at the recent attention on clinical pharmacy. The present bibliometrics analysis may provide a comprehensive overview and valuable reference for future researchers and practitioners in the research field of pharmaceutical care.

Bibliometric analysis of research relating to the use of herbal medicine for rheumatoid arthritis between 1991 to 2021.

Background:Rheumatoid arthritis (RA) is an inflammatory autoimmune disease, which is well known for its poor symptoms, and the incidence is increasing worldwide. Although conventional medicines are practiced initially, patients often move or accompany to complementary and alternative medicines for better outcomes. Herbal medications, one of traditional medicinal approach, are widely used in clinical conditions. However, no research has broadly reviewed the current research trends regarding the scope of herbal medicines in RA. The aim of this study was to conduct a bibliometric analysis of applications of herbal medicine for RA from 1991 to the presentMethods:We retrieved literature on herbal medicine for RA from the Web of Science database from 1991 to 2021. The VOSviewer program was used to analyze keywords, authors, countries, and organizations through visual knowledge mapping to assess the research hotspots and trends.Results:A total of 516 articles were included in the analysis, which showed an increasing trend in the number of publications over time. Four clusters were identified from the keyword analysis: complementary and alternative medicine cluster, mechanism of the pain cluster, control for the pain cluster, and recent research trend cluster. People’s Republic of China published 250 articles, which was the greatest number of publications, followed by the United States of America (82 articles) and South Korea (52 articles). Furthermore, Moudgil, KD of the University of Maryland published 15 articles about the mechanism of herbal medicine on autoimmune arthritis and their interaction with various drugs. Lu, AP of the Hong Kong Baptist University published 14 articles about herbal medicine interactions. On an institutional level, the China Academy of Chinese Medical Science published 33 articles, followed by the Hong Kong Baptist University and the University of Maryland with 27 and 20 articles, respectively. Clusters of organizations from the People’s Republic of China and the United States of America revealed higher average citations for earlier average publication years.Conclusions:This bibliometric study identified trends in herbal medicine for RA from 1991 to 2021, which may guide the hot topics and future directions in this research field.

A Research on Violence Against Women: Are the Trends Growing?

Objectives: Violence against women is a global public health problem. Although there has been much research done on violence against women, there are few studies that provide the current scientific production. Methods: In this study, bibliometric analysis has been used to evaluate the 1984 documents from 1986 to 2020 based on the Scopus database. These documents were analyzed quantitatively by the Bibliometric R Package and the VOS viewer software. In addition, the 20 top-cited papers were analyzed qualitatively. Results: The research findings show that the United States is a leader in this field with the most highly cited articles and also the greatest number of publications followed by the United Kingdom, Canada, Australia, and South Africa. A total of 1984 documents were collected from the Scopus database and were analyzed in the Bibliometric R Research Package and the VOSviewer software. The results demonstrated that the average citations per year for each document were 23.39% and the annual scientific production growth rate was 16.86%. The keywords analysis indicates that most articles focus on “sexual violence”, “sexual assault”, “intimate partner violence”, “violence against women”, “sexual abuse”, “domestic violence”, “child sexual abuse”, “prevention”, and “rape.” Sources such as the “Journal of Interpersonal Violence”, “Journal of Violence Against Woman”, “Journal of Violence and Victims”, “Psychology of Women Quarterly”, “Journal of Adolescent Health”, “Journal of Consulting and Clinical Psychology”, “American Journal of Public Health”, “Journal of Consulting and Clinical Psychology”, and “American Journal of Public Health”, and “The Lancet” are the top most productive in this field. Discussion: Examining the articles showed that the vast majority of women have experienced verbal, sexual, intimate partner violence, cyber harassment, and so on.

Bibliometric Mapping of Metaverse in Education

This research aims to create a bibliometric map of studies on the use of metaverse in education. We used the bibliometric mapping technique from an international viewpoint to assess trends in the area of metaverse research on education by disclosing the author, publication, keyword, journal, country, and citation factors. Most research on the topic was published in Computers Education. Results indicate that Hwang G.J. is the most relevant author. National Taiwan Normal University and National Taiwan University of Science and Technology are the most relevant universities. USA has the most publications, co-authored publications, single-national publications, and cited articles overall. China is the nation with the greatest number of publications from other countries. Denmark is regarded as being at the top in the field of average citations per article. The terms "augmented reality", "virtual reality" and "second life" is sub-applications of the Metaverse environment, and are often used keywords. Over time, we can observe that prior research on “second life”, “virtual worlds” and “virtual environments” were gradually superseded by studies on “augmented reality”, “virtual reality”, “immersive virtual reality”, and “VR”. Over time, the phrase "metaverse" may become one of these tendencies. The papers in this research were subjected to cluster analysis. All clusters appear to involve “virtual reality”. Additionally, “augmented reality” was included in three clusters. Examining the measured network analysis of the authors reveals that they are clustered into five separate groups.

Development of the Arabic Health Measures database: a bibliometric analysis of Arabic health-related measures

BackgroundTo develop an open-access database of Arabic health measures intended for use by researchers and healthcare providers, along with a bibliometric analysis of the measures included in the database.MethodsA search was conducted up to 31 December 2021 in PubMed, Embase, CINAHL, SAGE, Springer and Elsevier for published articles or abstracts with keywords “Arabic” AND “translation”, “adaptation” OR “validation”. Information on the measure and the methodology used in the study was then entered into a database. An open-access platform was developed to allow users to search for measures according to their needs. A bibliometric analysis of the articles and measures was then conducted.ResultsA total of 894 publications met the inclusion criteria. The articles discussed 716 measures that were developed using participants from at least 38 countries. The number of measures for adults was five times that for children. Mental health was the most frequent construct assessed (11.5%), followed by “function/disability” measures (10.6%). The majority of measures (54%) required 5 minutes or less to complete. Approximately 17% of the tools were available directly from the article. Saudi Arabia and Lebanon had the greatest number of publications, with 217 (23%) and 114 (12%), respectively. The majority of the publications included reporting of the validation and reliability of the instruments (64% and 56%, respectively).ConclusionsThere is a paucity of research on the quantity and quality of Arabic health measures. Similar to previous reviews, we found the number of publications on Arabic measures to be limited in comparison to those in English; however, it is encouraging that the number of publications appears to have increased steadily over the past decade. While we found the majority of publications reported on psychometric testing, we are unable to comment on the quality of the methodology used, and further investigation into this area is recommended. As the Arabic Health Measures database will facilitate the search for health instruments that have published data on their development, this will increase their visibility and use in research and clinical settings.

Birds and Natura 2000: a review of the scientific literature

Summary The Natura 2000 network, the pillar of biodiversity conservation in Europe, still shows some knowledge gaps after almost 30 years since its implementation. As birds are a taxonomic group that is underrepresented in the literature related to Natura 2000 compared to their importance in the EU Directives, this review investigated the characteristics of the scientific research dedicated to birds in relation to Natura 2000. This review focused on 169 peer-reviewed articles covering a period of 25 years (1995–2019). Most studies were set within single Natura 2000 site or regions within countries, and concerned terrestrial habitats, particularly wetlands. The terrestrial Mediterranean biogeographical region and marine Atlantic region had the greatest number of publications, while Spain, Italy, and France were the countries with the highest number of reviewed articles. The number of publications was correlated to Natura 2000 coverage at both country and biogeographical region level. Bird species were studied mainly at a community or single-species level and most publications studied distribution and occurrence of the bird species of interest, while very few assessed the conservation status of the species. Only a few articles set within Natura 2000 sites addressed the issues of habitat suitability for birds or the effectiveness of conservation efforts. Both Annex I and non-Annex I bird species were examined in the literature, with most species having decreasing population trends at the European scale. Future research on bird conservation and Natura 2000 should focus on marine ecosystems as well as habitats that have received less attention despite their important role in a changing future (alpine and urban types). Moreover, future studies should encompass larger spatial scales and those species for which status and trends are still not thoroughly investigated. Finally, it would be important to enhance research efforts on the conservation status and effectiveness in relation to the network.

Deciphering the focuses and trends in skin regeneration research through bibliometric analyses.

Increasing attention to skin regeneration has rapidly broadened research on the topic. However, no bibliometric analysis of the field’s research trends has yet been conducted. In response to this research gap, this study analyzed the publication patterns and progress of skin regeneration research worldwide using a bibliometric analysis of 1,471 papers comprising 1,227 (83.4%) original articles and 244 (16.6%) reviews sourced from a Web of Science search. Publication distribution was analyzed by country/region, institution, journal, and author. The frequency of keywords was assessed to prepare a bibliometric map of the development trends in skin regeneration research. China and the United States were the most productive countries in the field: China had the greatest number of publications at 433 (29.4%) and the United States had the highest H-index ranking (59 with 15,373 citations or 31.9%). Author keywords were classified into four clusters: stem cell, biomaterial, tissue engineering, and wound dressing. “Stem cells,” “chitosan,” “tissue engineering,” and “wound dressings” were the most frequent keywords in each cluster; therefore, they reflected the field’s current focus areas. “Immunomodulation,” “aloe vera,” “extracellular vesicles,” “injectable hydrogel,” and “three-dimensional (3D) bioprinting” were relatively new keywords, indicating that biomaterials for skin regeneration and 3D bioprinting are promising research hotspots in the field. Moreover, clinical studies on new dressings and techniques to accelerate skin regeneration deserve more attention. By uncovering current and future research hotspots, this analysis offers insights that may be useful for both new and experienced scholars striving to expand research and innovation in the field of skin regeneration.

Characteristics from the 100 most influential articles on carotid stenosis.

There are three main competing treatment modalities for carotid artery stenosis (CS), i.e., carotid endarterectomy (CEA), carotid artery angioplasty/stenting (CAS), and medical treatment. In this study, we analyzed the performance and trends of CS research through bibliometric analysis. We searched the Thomson Reuters Web of Science citation indexing database. The key words used in the search were "carotid artery" and "carotid stenosis". The top 100 most cited manuscripts (T100) were analyzed based on title, author, institution, country of origin, year of publication, and topic. The T100 were published between 1990 and 2016. The Stroke published the most manuscripts (n=22) and the New England Journal of Medicine was the most cited (n=15,113). The United States had the greatest number of publications (n=43), and the University of Oxford was the institution with the most publications (n=7). Peter M. Rothwell was the corresponding author with the most publications (n=10). The main topics were in the following categories: CEA (n=22), medication (n=11), CAS (n=9), diagnosis (n=44), and CEA vs. CAS (n=14). This bibliometric analysis of CS research provides insight into publication trends and perspective on the treatment of CS.

Knowledge Mapping of Olfactory Dysfunction: A Bibliometric Study.

BackgroundOlfaction is one of the five basic senses of human beings. As such, olfactory dysfunction seriously affects patients' quality of life and can even endanger them. In recent years, olfactory dysfunction has attracted greater research interest, and numerous studies have been published on olfactory dysfunction. However, there are few studies on olfactory dysfunction through bibliometric analysis. This study aims to describe the current situation and identify the foci and potential new research directions of olfactory dysfunction using a bibliometric approach.MethodsArticles related to olfactory dysfunction published from 2002 to 2021 were located in the Web of Science Core Collection of Clarivate Analytics (London, UK). Bibliometric analyses were conducted with the CiteSpace (Chaomei Chen, Drexel University, Philadelphia, PA, USA) and VOSviewer (Center for Science and Technology Studies, Leiden University, Leiden, Netherlands) software programs.ResultsThe number of articles published each year showed an upward trend, especially in 2020, where a sharp increase had occurred due to the coronavirus disease 2019 (COVID-19) pandemic. The United States was the country with the most publications and the strongest international cooperation. In terms of institutions, the greatest number of publications from a single institution came from Dresden University of Technology. Thomas Hummel was the author who had contributed the most articles. An analysis of co-citation networks and burst keywords in the field revealed a shift from “gonadotropin-releasing hormone” and “apoptosis” earlier on to “olfactory training,” “COVID-19,” and “Parkinson's disease” more recently. “Outcome,” “COVID-19,” “infection,” and “pathogenesis” are topics of the research frontier and hotspots.ConclusionMore attention has been paid to olfactory dysfunction as the understanding of it has improved in the past 20 years. This study provides researchers with an objective, systematic, and comprehensive analysis of the literature on olfactory dysfunction. The current frontier areas and hotspots in the field focus on the pathological mechanisms of olfactory dysfunction after infection with COVID-19 and its different prognoses. The pathophysiological mechanism of olfactory dysfunction in neurodegenerative diseases and COVID-19 will be a primary future research direction.

A Scientometric Analysis and Visualization Discovery of Enhanced Recovery After Surgery.

BackgroundEnhanced recovery after surgery (ERAS), a new clinical surgical concept, has been applied in many surgical disciplines with good clinical results for the past 20 years. Bibliometric analysis is an effective method to quantitatively evaluate the academic productivity. This report aimed to perform a scientometric analysis of the ERAS research status and research hotspots.MethodsComprehensive scientific mapping analysis of a wide range of literature metadata using the scientometric tools, including the Bibliometrix R Package, Biblioshiny, and CiteSpace. Data were retrieved from the Web of Science Core Collection database of original articles from 2001 to 2020. Specific indicators and maps were analyzed to show the co-authorship, co-institute, co-country, co-citation, and international cooperation. Automatic literature screening, unsupervised cluster filtering, and topic cluster identification methods were used to display the conceptual framework and thematic evolution.ResultsA total of 1,403 research projects drafted by 6,966 authors and published in 413 sources were found. There was an exponential growth in the number of publications on ERAS. There were 709 collaborations between authors from different countries, and the US, China, and the UK had the greatest number of publications. The WORLD JOURNAL OF SURGERY, located in Bradford’s Law 1, had the highest number of published articles (n = 1,276; total citations = 3,193). CiteSpace network analysis revealed 15 highly correlated cluster ERAS studies, and the earliest study was on colonic surgery, and ERAS was recently applied in cardiac surgery. The etiology of ERAS is constantly evolving, with surgery and length of hospital as the main topics. Meta-analyses and perioperative care have tended to decline.ConclusionThis is the first scientometric analysis of ERAS to provide descriptive quantitative indicators. This can provide a better understanding of how the field has evolved over the past 20 years, help identify research trends, and provide insights and research directions for academic researchers, policymakers, and medical practitioners who want to collaborate in these areas in the future.

A bibliometric analysis of the cannabis and cannabinoid research literature

BackgroundCannabis refers to a plant in the family Cannabaceae, which has been used medically, recreationally, and industrially. The last two decades, in particular, have seen a large increase in the volume of literature on this topic. The present bibliometric analysis aims to capture the characteristics of scholarly journal publications on the topic of cannabis and cannabinoid research.MethodsSearches were run on the Scopus database on April 02, 2021, as follows “(TITLE (cannabi* OR hashish OR marijuana OR marihuana)) AND ( LIMIT-TO ( DOCTYPE,"ar" ) OR LIMIT-TO ( DOCTYPE,"re" ) )”. Results were exported on the same day to prevent discrepancies between daily database updates. Only “article” and “review” publication types were included; no further search limits were applied. The “article” publication type includes publications featuring original research, whereas “review” includes reviews and conference papers. The following data were collected: number of publications (in total and per year), authors, and journals; open access status; publications per journal; journals publishing the highest volume of literature and their impact factors, language of publication; document type; publication country; author affiliations; funding sponsors; most highly cited publications; and most highly published authors. Trends in this subset of publications were identified and presented. Bibliometric networks were constructed using the software tool VOSviewer.ResultsA total of 29 802 publications (10 214 open access), published by 65 109 authors, were published in 5474 journals from 1829 to 2021. The greatest number of publications was published over the last 20 years. The journal that published the largest number of publications was Drug and Alcohol Dependence (n = 705). The most productive countries included the USA (n = 12 420), the UK (n = 2236), and Canada (n = 2062); many of the most common institutional affiliations and funding sponsors originated from these countries.ConclusionsThe number of publications published on the topic of cannabis follows an upward trend. Over the past 20 years, the volume of cannabis research has grown steeply, which can be attributed to a large amount of funding dedicated to researching this topic. Future research should continue to investigate changes in the publication characteristics of emerging research, as the volume of publications on this topic is expected to rapidly grow.

The journals, World Neurosurgery and Journal of Neurosurgery had the most number of publications and the most cited publications. Keyword analysis showed that immune therapy, chemotherapy, and the Brachyury-related study were becoming more popular. ConclusionsThe present study provided both a comprehensive insight of chordoma research, as well as a description of future areas of research.

Investigating the landscape and trajectory of spina bifida research in Asia: a bibliometric analysis.

Spina bifida is a type of a neural tube defect which affects 243.14 per 100,000 babies in Asia. Research articles on spina bifida have increased in the recent years. However, no study has focused on the research trends in this field in Asia. A systematic review of literature on spina bifida in Asia was performed using the Scopus database from inception to 2020. All published studies on spina bifida conducted in or published by authors from Asia were included in our analysis. Bibliometric information was obtained from Scopus and bibliometrics diagrams were created using VOSviewer software. A total of 652 articles were obtained in this study. The number of publications showed an upward trend starting 2000s. The country with the greatest number of publications was Japan while All India Institute of Medical Sciences was the most productive institution in spina bifida research in Asia. The current focus of this field in Asia was prevalence of spina bifida, prenatal diagnosis, folic acid supplementation, and complications of spina bifida. Future areas of research in spina bifida include the genetic basis of neural tube defects and the use of stem cell technology as therapies for spina bifida. This is the first bibliometric analysis on spina bifida in Asia. It showed the trend and future areas of research on spina bifida in Asia. Despite the increase in scientific literature on spina bifida research, more research outputs and collaborations are needed especially in developing countries in Asia.

Global and Current Research Trends of Unilateral Biportal Endoscopy/Biportal Endoscopic Spinal Surgery in the Treatment of Lumbar Degenerative Diseases: A Bibliometric and Visualization Study.

The study aimed to make a bibliometric analysis of the current research situation in unilateral biportal endoscopy/biportal endoscopic spinal surgery (UBE/BESS). Research data sets were acquired from the Web of Science database. The study chosed “biportal endoscopic spinal surgery” OR “two portal endoscopic spinal surgery” OR “percutaneous biportal endoscopic decompression” OR “unilateral biportal endoscopy” OR “irrigation endoscopic discectomy” as the search terms. The literature search was limited to articles published before March 5, 2021. We only included original articles and reviews. VOS viewer and Citespace software were used to analyze the data and generate visualization knowledge maps. Annual trend of publications, distribution, H‐index status, co‐authorship status, and research hotspots were analyzed. A total of 74 publications met the requirement. The sum number of citations was 31,204, in which 19,336 were no self‐citations. The average citation of all the papers was 21.84 times. The H‐index of all the publications was 85. South Korea's total number of articles was far higher than that of other countries and regions (61, 82.4%), followed by United Arab Emirates, Egypt, and Peoples Republic of China (three, ranking second, accounting for 12.2% of the total). For the most productive authors, Choi ranked first with 21 articles, Kim ranked second with 16 articles, and Heo ranked third with 12 articles. The journal with the greatest number of publications was World Neurosurgery, with a total of 18 (39.1%) papers. Clinics in Orthopedic Surgery ranked second with six (13.0%) papers. In third place, there were fix articles published by Asian Spine Journal and Neurospine, accounting for 21.8% of the total articles. These top three journals accounted for 73.9% of all the papers. Spondylolisthesis and endoscopic decompression were the research hotspots in recent years. The number of publications has showed an upward trend with a stable rise in recent years. South Korea is the country with the highest productivity, not only in quality, but also in quantity. Barun Hosp and Leon Wiltse Mem Hosphave published most articles. Choi is the most productive author. World Neurosurgery is the most productive journal. Spondylolisthesis and endoscopic decompression are the research hotspots in recent years. Indeed, this study provides new insight into the growth and development of UBE/BESS.

COVID-19 and Pregnancy: Citation Network Analysis and Evidence Synthesis.

BackgroundCOVID-19 spread quickly around the world shortly after the first outbreaks of the new coronavirus disease at the end of December 2019, affecting all populations, including pregnant women.ObjectiveThe aim of this study was to analyze the relationship between different publications on COVID-19 in pregnancy and their authors through citation networks, as well as to identify the research areas and to determine the publication that has been the most highly cited.MethodsThe search for publications was carried out through the Web of Science database using terms such as “pregnancy,” “SARS-CoV-2,” “pregnant,” and “COVID-19” for the period between January and December 2020. Citation Network Explorer software was used for publication analysis and VOSviewer software was used to construct the figures. This approach enabled an in-depth network analysis to visualize the connections between the related elements and explain their network structure.ResultsA total of 1330 publications and 5531 citation networks were identified in the search, with July being the month with the largest number of publications, and the United States, China, and England as the countries with the greatest number of publications. The most cited publication was “Clinical characteristics and intrauterine vertical transmission potential of COVID-19 infection in nine pregnant women: a retrospective review of medical records” by Chen and colleagues, which was published in March 2020. Six groups identified as being close in the citation network reflect multidisciplinary research, including clinical characteristics and outcomes in pregnancy, vertical transmission, delivery mode, and psychological impacts of the pandemic on pregnant women.ConclusionsThousands of articles on COVID-19 have been published in several journals since the disease first emerged. Identifying relevant publications and obtaining a global view of the main papers published on COVID-19 and pregnancy can lead to a better understanding of the topic. With the accumulation of scientific knowledge, we now know that the clinical features of COVID-19 during pregnancy are generally similar to those of infected nonpregnant women. There is a small increase in frequency of preterm birth and cesarean birth, related to severe maternal illness. Vaccination for all pregnant women is recommended. Several agents are being evaluated for the treatment of COVID-19, but with minimal or no information on safety in pregnancy. These results could form the basis for further research. Future bibliometric and scientometric studies on COVID-19 should provide updated information to analyze other relevant indicators in this field.

Worldwide Research Trends on Diabetic Foot Ulcers (2004-2020): Suggestions for Researchers.

Objectives Diabetic foot ulcer (DFU) is one of the devastating complications of diabetes. It has high mortality and disability rates. The number of research articles on DFUs has increased. This study was designed to explore the global trends and research hotspots of DFUs to benefit researchers in shaping future research directions. Methods Literatures relating to DFU from 2004 to 2020 were retrieved from the Science Citation Index Expanded (SCI-expanded) of Web of Science Core Collection (WoSCC). The current status of DFU research (including publications, journals, the performances of relevant countries, institutions, and authors and the research trends and hotspots of DFU) was analyzed with the WoSCC. VOSviewer v1.6.10.0 was utilised for cocitation, coauthorship, cooccurrence analyses, and bibliographic coupling. Results A total of 5869 publications on DFUs were retrieved. We performed a longitudinal review of publications over 17 years: 4500 articles and 865 review articles on DFUs published from 2004 to 2020 were analyzed. The total citation was 107,296. The USA (n = 1866), England (n = 606), and China (n = 599) were the three largest contributors. The University of Washington had the greatest number of publications within this time period (n = 103), and it had the most cooperative units and was in the core position in all research institutions, followed by the University of Manchester (n = 94) and the University of Miami (n = 92). Armstrong DG (91/1.69%) and Lavery LA (55/1.19%) should be regarded as scholars who have made outstanding contributions. The top journal with the greatest total link strength was Diabetes Care. Analysis showed that the global research hotspots of DFU focused on lower limb amputation, diabetic foot infection, and treatment and management of DFU. Studies on osteomyelitis, wound therapy and management, multidisciplinary integration and mechanism of DFUs, and its related diseases are the research fronts that should be closely watched in the future. Conclusions This study revealed the current research status and hotspots in the domain of DFU over the past 17 years, which can help researchers to further pinpoint potential perspectives on hot topics and research frontiers.

Determining global trends in syngas fermentation research through a bibliometric analysis

Syngas fermentation, in which microorganisms convert H2, CO, and CO2 to acids and alcohols, is a promising alternative for carbon cycling and valorization. The intellectual landscape of the topic was characterized through a bibliometric analysis using a search query (SQ) that included all relevant documents on syngas fermentation available through the Web of Science database up to December 31st, 2021. The SQ was validated with a preliminary analysis in bibliometrix and a review of titles and abstracts of all sources. Although syngas fermentation began in the early 1980s, it grew rapidly beginning in 2008, with 92.5% of total publications and 87.3% of total citations from 2008 to 2021. The field has been steadily moving from fundamentals towards applications, suggesting that the field is maturing scientifically. The greatest number of publications and citations are from the USA, and researchers in China, Germany, and Spain also are highly active. Although collaborations have increased in the past few years, author-cluster analysis shows specialized research domains with little collaboration between groups. Based on topic trends, the main challenges to be address are related to mass-transfer limitations, and researchers are starting to explore mixed cultures, genetic engineering, microbial chain elongation, and biorefineries.
