COVID-19 and urology: A bibliometric analysis of the literature

A visualized and bibliometric analysis of nursing research during the COVID-19 pandemic

BACKGROUND

The global spread of Coronavirus disease 2019 (COVID-19) has been increasing since December 2019. A total of 8460 publications were obtained from the Web of Science Core Collection from 2019 to 2023, providing insights into the progress of nursing research throughout the COVID-19 pandemic.

METHODS

Bibliometric analysis was conducted on these articles using CiteSpace. The analysis focused on examining the distribution of these publications in terms of space and time, distribution of authors, subject categories, distribution of topics, and cited references.

RESULTS

These results may be explained from 3 perspectives. Initially, the number of yearly publications on nursing research consistently increased during the COVID-19 pandemic. Furthermore, a co-occurrence analysis of the countries and the authors revealed that certain countries, including the United States, China, and England, have successfully implemented organized and standardized nursing models. These countries also have well-developed and established nursing research systems. Notably, academic communities in specific regions, such as the team led by MD Stefan Gravenstein, Mor Vincent, and White Elizabeth at Brown University in the United States, have emerged as leaders in this field. Furthermore, examining the papers' subject categories and topic distribution indicate that nursing during the COVID-19 pandemic has been predominantly interdisciplinary, encompassing various disciplines such as clinical medicine, essential medicine, psychology, public health management, and even telematics science.

CONCLUSION SUBSECTIONGS

Our study provided valuable insights into acquiring knowledge on nursing research during the COVID-19 pandemic, pinpointed possible partners for researchers interested in nursing, and uncovered prevalent research patterns and popular subjects.

BACKGROUND

The coronavirus disease-2019 (COVID-19) pandemic has had a dramatic impact on global health, with orthopedics among the most affected specialties. An increasing number of COVID-19-related orthopedic studies have been published. The purpose of this study was to analyze the orthopedic literature published during the COVID-19 pandemic to guide future research.

METHODS

The Scopus database was searched for relevant literature published between 2020 and 2022. The keywords used in the retrieval process were ("COVID-19" OR "Coronavirus" OR "2019-nCoV" OR "SARS-CoV-2" OR "Betacoronavirus" OR "novel coronavirus 2019" OR "novel coronavirus" OR "coronavirus-19" OR "COVID 19" OR "nCOV" OR "COVID-2019" OR "COVID 2019") and ("orthopedic" OR "orthopedics" OR "orthopedic" OR "orthopedical" OR "orthopedical" OR "orthopedics"). Spreadsheet software (Excel, Microsoft Corp., Redmond, WA) was used to analyze the top 10 cited authors, countries, journals, and articles. The top 5 publication types were also analyzed. VOSviewer (Center for Science and Technology Studies, Leiden, Netherlands) was used to network and visualize the literature.

RESULTS

A total of 1619 publications relevant to COVID-19 and orthopedics were reviewed. Among these publications, the most active country, author, and publication type included the United States, Vaishya R, and original articles, respectively. The most frequently used keywords were human, coronavirus disease-2019, pandemic, and orthopedics. The Journal of Bone and Joint Surgery American Volume was the most cited journal, whereas the greatest number of articles was published in the Journal of Clinical Orthopedics and Trauma.

CONCLUSIONS

This study provides a perspective on the development of orthopedic publications during the COVID-19 pandemic and evidence for researchers worldwide to strengthen global cooperation in fighting the epidemic.

COVID-19 and chronic kidney disease: a bibliometric analysis

Background

The COVID-19 pandemic has caused over 656 million confirmed cases and over 6.6 million deaths worldwide. Chronic kidney disease (CKD) is considered a high-risk factor for COVID-19; therefore, considerable research has been conducted in this field. Therefore, this study aims to conduct a bibliometric analysis of publications related to COVID-19 and CKD.

Methods

Publications were retrieved from the Web of Science Core Collection database on 16 January 2023 and screened based on inclusion criteria. Then the authors used Microsoft Excel and CiteSpace to analyze the included publications from the following seven aspects: countries/regions, institutions, journals, authors, cited references, and keywords.

Results

In total, 622 publications were included in the study. The USA has the most publications in this field, followed by China. The Icahn School of Medicine at Mount Sinai and Harvard Medical School had the highest number of publications in the field. Journal of Clinical Medicine had the largest number of publications, and Lancet was the most cited journal. Alberto Ortiz was the author with the largest number of publications, but there were no influential authors in this field. The highly cited references are mainly clinical studies on COVID-19. Research hotspots in this field include end-stage recent disease, cardiovascular disease, kidney metastasis, diabetes Mellitus, acute kidney injury, meta-analysis, and consistent plasma.

Conclusions

The USA, China, and some European countries and their institutions are major contributors to these publications. End-stage renal disease, acute kidney injury, kidney transplantation and convalescent plasma are current hot topics in the field.

Biofuels and Nanocatalysts: Python Boosting Visualization of Similarities

Among the most relevant themes of modernity, using renewable resources to produce biofuels attracts several countries' attention, constituting a vital part of the global geopolitical chessboard since humanity's energy needs will grow faster and faster. Fortunately, advances in personal computing associated with free and open-source software production facilitate this work of prospecting and understanding complex scenarios. Thus, for the development of this work, the keywords "biofuel" and "nanocatalyst" were delivered to the Scopus database, which returned 1071 scientific articles. The titles and abstracts of these papers were saved in Research Information Systems (RIS) format and submitted to automatic analysis via the Visualization of Similarities Method implemented in VOSviewer 1.6.18 software. Then, the data extracted from the VOSviewer were processed by software written in Python, which allowed the use of the network data generated by the Visualization of Similarities Method. Thus, it was possible to establish the relationships for the pair between the nodes of all clusters classified by Link Strength Between Items or Terms (LSBI) or by year. Indeed, other associations should arouse particular interest in the readers. However, here, the option was for a numerical criterion. However, all data are freely available, and stakeholders can infer other specific connections directly. Therefore, this innovative approach allowed inferring that the most recent pairs of terms associate the need to produce biofuels from microorganisms' oils besides cerium oxide nanoparticles to improve the performance of fuel mixtures by reducing the emission of hydrocarbons (HC) and oxides of nitrogen (NOx).

Bibliometric evaluation of 2020-2022 publications on COVID-19-related cardiovascular disease

Objective

This study aimed to investigate the international scientific output regarding the relationship between COVID-19 and cardiovascular diseases (CVDs) through a bibliometric analysis and explore research hotspots in this field.

Methods

We searched the Web of Science Core Collection for publications and used different types of software, such as R, CiteSpace, and VOSviewer, to analyze and visualize the data.

Results

A total of 10,055 publications were retrieved as of the 13 December 2022, based on the inclusion criteria after screening. The USA and China lead in the quantity and quality of publications in this field. Based on Bradford's law, 63 journals were considered core journals in the field. Co-cited references and keywords analysis indicated that researchers paid particular attention to cardiovascular comorbidities, outcomes, and COVID-19 regenerative medicine. In summary, with increasing COVID-19 research related to CVD, more attention might be drawn to the relationship between these two diseases.

Conclusion

The hotspots in this field may continue to revolve around cardiovascular comorbidities, outcomes, and COVID-19 regenerative medicine. Owing to the different situations faced by different groups with COVID-19, further exploration of the related factors specific to each of these groups, e.g., history or no history of heart failure, is needed, with a view to providing a reference for intervention measures in COVID-19 research.

Consequences of SARS-CoV-2 pandemic on urological surgery in France: a nationwide analysis of the healthcare system database

The SARS-CoV-2 outbreak overwhelmed the healthcare systems worldwide. Saturation of hospitals and the risk of contagion led to a reduction in the care of other diseases.

OBJECTIVE

To determine the impact of SARS-CoV-2 pandemic on urological surgery in France during the year 2020.

DESIGN, SETTING AND PARTICIPANTS

An observational descriptive study was conducted on anonymised data collected from the national healthcare database established each year as part of the Program for the Medicalization of Information Systems in Medicine, Surgery, Obstetrics and Odontology.

INTERVENTION

None.

PRIMARY AND SECONDARY OUTCOME MEASURES

We gathered the number of urology surgical procedures carried out between 2010 and 2019, and we observed the difference between the forecast and actual number of urological surgeries performed in 2020.

RESULTS

Urological surgeries decreased by 11.4%, non-oncological surgeries being more affected (-13.1%) than oncological ones (-4.1%). Among the most relevant surgeries, female urinary incontinence (-44.7%) and benign prostatic hyperplasia (-20.8%) were the most impacted ones, followed by kidney cancer (-9%), urolithiasis (-8.7%), radical cystectomy for bladder cancer (-6.1%), prostate cancer (-3.6%) and transurethral resection of bladder tumour (-2%). Public hospitals had a more reduced activity (-17.7%) than private ones (-9.1%). Finally, the distribution of the reduction in urological activities by region did not correspond to the regional burden of SARS-CoV-2.

CONCLUSIONS

Urological care was severely affected during SARS-CoV-2 pandemic. Even if oncological surgeries were prioritised, the longer it takes to receive appropriate care, the greater the risk on survival impact.

TRIAL REGISTRATION

The data collection and analysis was authorised by the French Data Protection Authority (CNIL) under the number1 861 282v2.

Bibliometric and Visualization Analysis of the Ecology of Men's Sexual and Reproductive Healthcare Research in MENA (1985-2022): Outputs, Trends, Shortcomings and Hotspots

Background

To date, no previous research assessed the bibliometrics of men's sexual and reproductive healthcare (SRHC) across Arab countries. This study appraised the current standing of men's SRHC research in the MENA (Middle East and North Africa) region.

Methods

We performed a bibliometric analysis to assess qualitatively and quantitatively the peer-reviewed articles published from Arab countries from inception to 2022. In addition, we conducted a visualization analysis, and assessed outputs, trends, shortcomings and hotspots over the given time period.

Results

There was a generally low numbers of publications, 98 studies were identified, all with cross-sectional design, and two thirds explored prevention and control of HIV/other STDs. Studies were published in 71 journals, of which the Eastern Mediterranean Health Journal, Journal of Egyptian Public Health Association, AIDS Care and BMC public health were most common. The Journal of Adolescent Health, Fertility Sterility and Journal of Cancer Survivorship were among the highest IF ranking. Publishers were commonly USA or UK-based, median journal IF was 2.09, and five articles were in journals of IF > 4. Saudi Arabia had the highest published output followed by Egypt, Jordan and Lebanon, while 10 Arab countries had no publications on the topic. Corresponding authors expertise fields were most commonly public health, infectious diseases and family medicine). Collaborations in-between MENA countries were notably low.

Conclusions

There is general paucity of published outputs on SRHC. More research across MENA is needed, with more inter-MENA collaborations, and with inclusion of countries that currently have no outputs on SRHC. In order to accomplish such goals, R&D funding and capacity building are required. Research and published outputs should address SRHC burdens.

A bibliometric analysis of COVID-19 publications in neurology by using the visual mapping method

Background

The characteristic symptom of coronavirus disease 2019 (COVID-19) is respiratory distress, but neurological symptoms are the most frequent extra-pulmonary symptoms. This study aims to explore the current status and hot topics of neurology-related research on COVID-19 using bibliometric analysis.

Methods

Publications regarding neurology and COVID-19 were retrieved from the Web of Science Core Collection (WoSCC) on March 28 2022. The Advanced search was conducted using “TS = (‘COVID 19’ or ‘Novel Coronavirus 2019’ or ‘Coronavirus disease 2019’ or ‘2019-nCOV’ or ‘SARS-CoV-2’ or ‘coronavirus-2’) and TS = (‘neurology’or ‘neurological’ or ‘nervous system’ or ‘neurodegenerative disease’ or ‘brain’ or ‘cerebra’ or ‘nerve’)”. Microsoft Excel 2010 and VOSviewer were used to characterize the largest contributors, including the authors, journals, institutions, and countries. The hot topics and knowledge network were analyzed by CiteSpace and VOSviewer.

Results

A total of 5,329 publications between 2020 and 2022 were retrieved. The United States, Italy, and the United Kingdom were three key contributors to this field. Harvard Medical School, the Tehran University of Medical Sciences, and the UCL Queen Square Institute of Neurology were the major institutions with the largest publications. Josef Finsterer from the University of São Paulo (Austria) was the most prolific author. Tom Solomon from the University of Liverpool (UK) was the most cited author. Neurological Sciences and Frontiers in Neurology were the first two most productive journals, while Journal of Neurology held the first in terms of total citations and citations per publication. Cerebrovascular diseases, neurodegenerative diseases, encephalitis and encephalopathy, neuroimmune complications, neurological presentation in children, long COVID and mental health, and telemedicine were the central topics regarding the neurology-related research on COVID-19.

Conclusion

Neurology-related research on COVID-19 has attracted considerable attention worldwide. Research topics shifted from “morality, autopsy, and telemedicine” in 2020 to various COVID-19-related neurological symptoms in 2021, such as “stroke,” “Alzheimer's disease,” “Parkinson's disease,” “Guillain–Barre syndrome,” “multiple sclerosis,” “seizures in children,” and “long COVID.” “Applications of telemedicine in neurology during COVID-19 pandemic,” “COVID-19-related neurological complications and mechanism,” and “long COVID” require further study.

A Bibliometric Analysis of Personal Protective Equipment and COVID-19 Researches

COVID-19, which occurred at the end of December 2019, has evolved into a global public health threat and affects every aspect of human life. COVID-19's high infectivity and mortality prompted governments and the scientific community to respond quickly to the pandemic outbreak. The application of personal protective equipment (PPE) is of great significance in overcoming the epidemic situation. Since the discovery of severe acute respiratory coronavirus 2 (SARS-CoV-2), bibliometric analysis has been widely used in many aspects of the COVID-19 epidemic. Although there are many reported studies about PPE and COVID-19, there is no study on the bibliometric analysis of these studies. The citation can be used as an indicator of the scientific influence of an article in its field. The aim of this study was to track the research trends and latest hotspots of COVID-19 in PPE by means of bibliometrics and visualization maps.
