[Bibliometric analysis of the Spanish scientific production in Infectious Diseases and Microbiology]

Bibliometric analysis of the Spanish scientific production in Infectious Diseases and Microbiology (2014-2021)

INTRODUCTION

The profound impact of the Covid-19 pandemic, together with other factors such as globalisation and climate change, has emphasised the growing relevance of Infectious Diseases and Microbiology.

METHODS

The Spanish scientific production in both categories of the Web of Science databases over the period 2014-2021 has been analysed.

RESULTS

8037 documents have been identified in Infectious Diseases and 12008 documents in Microbiology (6th most productive country worldwide in both cases, with growth rates of 41% and 46.2%, respectively). Both areas present a high degree of international collaboration (45-48% of the documents) and between 45-66% of the documents have been published in journals of excellence (first quartile) according to the rankings of the Journal Citation Reports.

CONCLUSIONS

Spain is in a prominent position worldwide in both areas, with an outstanding scientific production in journals of high visibility and impact.

Research in Cerebrospinal Fluid Leak (Rhinorrhea and Otorrhea): A Bibliometric Analysis From 1945 to 2018

Objective

In this study, we aimed to analyze research activity on cerebrospinal fluid (CSF) leaks in general and CSF rhinorrhea and otorrhea in particular and to identify the main topic clusters in these areas.

Methods

We identified all relevant documents, using the medical subject heading (MeSH) term “Cerebrospinal Fluid Leak”, that are indexed in the MEDLINE database between 1945 and 2018. We performed a descriptive bibliometric analysis and analyses of networks and research clusters in order to identify the main topic areas of research.

Results

From 1945 to 2018, a total of 4,130 records were published with the term CSF leak, including 2,821 documents (68.1%) with the term CSF rhinorrhea and 1,040 documents (25.8%) with CSF otorrhea. The number of documents published increased from 10 in 1945-49 to 642 in 2010-14. Articles represented the dominant document type (86.8% of the documents analyzed), while case reports were the main type of study (37.4%). In terms of geographical distribution, researchers from the USA led in the number of signatures (39.1%), followed by those from the UK (7.5%). The most active areas of research in the field were “Postoperative Complications,” “Tomography, X-Ray Computed,” and “Magnetic Resonance Imaging.” The terms “Adults,” “Young Adult,” and “Middle-Aged” were most common in CSF rhinorrhea research; and the terms “Infant,” “Child, Preschool,” “Child,” and “Adolescent” were more common in CSF otorrhea.

Conclusions

Based on our findings, articles and case reports related to “Surgery” and “Postoperative Complications” associated with the diagnosis are the main topics of study, highlighting the importance of this document type in advancing knowledge in the field.

Wastewater Treatment Costs: A Research Overview through Bibliometric Analysis

Given the problem of water scarcity and the importance of this resource for the sustainability of the planet, wastewater treatment and its costs have become a key issue for proper water management. Using bibliometric analysis of publications in the Web of Science database, this study presents an overview of the research on wastewater treatment costs in the period 1950–2020. The worldwide search returned 22,788 articles for wastewater treatment costs, which compares poorly to the results for research on wastewater treatment, accounting for only 12.34% of the total output on wastewater treatment. The findings of this study reveal the leading countries in this field of research (China, USA, India, Spain and the UK), with the articles being published in a wide range of high impact journals. Similarly, there are very few results on UV and chlorination costs, despite the importance of these two treatments for wastewater disinfection and reuse. This study is aimed at researchers in this field, helping them to identify recent trends, and at the main institutions in the scientific community working on this subject.

Clinical care of patients with HIV

There has been a significant change in the clinical characteristics of people living with HIV, with new needs arising that must be tackled. The life expectancy of a subject diagnosed early with HIV infection and recei-ving suppressive antiretroviral therapy is currently on a par with the life expectancy of the general popula-tion. HIV is now a chronic treatable disease and requires a multidisciplinary approach that includes both the hospital medicine specialties and primary care physicians. The fragmented model to provide social and medical healthcare hinders the proper management of patients with HIV infection. There is significant clinical and geographical variability in the healthcare provided for HIV infection in Spain and the need to define and implement new models of healthcare delivery for this disease has been identified.

Sustainable Water Resources Management: A Bibliometric Overview

While global water demand continues increasing, the quantity and quality of water resources is decreasing in many regions. Conflicts over competition in the use of water are likely to increase as societies face social, economic and political challenges, especially aggravated by climate change. In this scenario, sustainable management of water resources is a key priority to meet the growing demand for water and to achieve a safe and environmentally sustainable future supply. The main objective of this article was to show an image of the international scientific production related to “Sustainable Water Resources Management” by using the comparative bibliometric study of the documents indexed in the WoS(Web of Science) and Scopus databases as a tool; and to analyze relevant aspects such as their coverage, correlation, overlap, growth, citation, dispersion or concentration, among others. For this purpose, and by means of an advanced search of terms, a representative set of 160 articles in WoS and 210 in Scopus were selected (with a time limit that limited the results to anything published before 2017, including 2017), which form the ad-hoc basis of the analysis. Their significant increase in both the number of articles and citations received in the last 10 years demonstrates the growing interest of the scientific community in its study. Regarding the analysis of the databases, although WoS and Scopus differ in terms of scope, volume of data and coverage policies, both information systems are complementary and non-exclusive. Despite their similarities, Scopus performs better coverage in the specific area of Sustainable Water Resource Management by collecting a greater number of articles and receiving a greater number of citations.

AIDS Clinical Research in Spain-Large HIV Population, Geniality of Doctors, and Missing Opportunities

The first cases of AIDS in Spain were reported in 1982. Since then over 85,000 persons with AIDS have been cumulated, with 60,000 deaths. Current estimates for people living with HIV are of 145,000, of whom 20% are unaware of it. This explains the still high rate of late HIV presenters. Although the HIV epidemic in Spain was originally driven mostly by injection drug users, since the year 2000 men having sex with men (MSM) account for most new incident HIV cases. Currently, MSM represent over 80% of new yearly HIV diagnoses. In the 80s, a subset of young doctors and nurses working at Internal Medicine hospital wards became deeply engaged in attending HIV-infected persons. Before the introduction of antiretrovirals in the earlier 1990s, diagnosis and treatment of opportunistic infections was their major task. A new wave of infectious diseases specialists was born. Following the wide introduction of triple combination therapy in the late 1990s, drug side effects and antiretroviral resistance led to built a core of highly devoted HIV specialists across the country. Since then, HIV medicine has improved and currently is largely conducted by multidisciplinary teams of health care providers working at hospital-based outclinics, where HIV-positive persons are generally seen every six months. Antiretroviral therapy is currently prescribed to roughly 75,000 persons, almost all attended at clinics belonging to the government health public system. Overall, the impact of HIV/AIDS publications by Spanish teams is the third most important in Europe. HIV research in Spain has classically been funded mostly by national and European public agencies along with pharma companies. Chronologically, some of the major contributions of Spanish HIV research are being in the field of tuberculosis, toxoplasmosis, leishmaniasis, HIV variants including HIV-2, drug resistance, pharmacology, antiretroviral drug-related toxicities, coinfection with viral hepatitis, design and participation in clinical trials with antiretrovirals, immunopathogenesis, ageing, and vaccine development.

A Map of Clinical Dermatology Research Centers in Spain: Results of the MaIND Study

BACKGROUND AND OBJECTIVE

Bibliometric indicators and analyses of clinical research articles can help to quantify the scientific production of hospitals and institutions and identify their main areas of research. The aim of this study was to draw up a bibliometric map of clinical research in dermatology by Spanish hospitals and institutions through an analysis of quantitative, qualitative, and topic-based variables.

MATERIAL AND METHOD

Bibliometric study of clinical research articles that met the inclusion criteria and had a definitive publication date between 2005 and 2014 in PubMed or Embase in which the corresponding author's affiliation was a Spanish dermatology department or institution.

RESULTS

Barcelona and Madrid were the provinces with the highest number of articles and citations. The centers with the most articles and citations were Hospital Clínic and Instituto Valenciano de Oncología. Those 2 hospitals also produced the highest number of articles on the most common research topic identified: melanoma. Because the articles were selected on the basis of the affiliation of the corresponding author to a Spanish dermatology center, this analysis does not include collaborative studies or clinical research studies led by nondermatology centers.

CONCLUSIONS

We have created a bibliometric map of clinical dermatology research in Spain that shows the distribution of scientific production and the main areas of research by province and hospital/institution. This map could be useful for education and research purposes.

Spanish Society of Vascular and Interventional Radiology (SERVEI) Bibliometric Study (2010-2015): What, How, and Where do Spanish Interventional Radiologists Publish?

PURPOSE

We analyzed the scientific production of members of the Spanish Society of Vascular and Interventional Radiology (SERVEI) from 2010 to 2015.

MATERIALS AND METHODS

We retrospectively analyzed the indexed scientific productivity of all SERVEI members for the last 6 years as measured by bibliometric indexes. Different databases were used (e.g., PubMed, Scopus, Web of Knowledge) to retrieve the total number of publications, number of citations, and h-index. Every article was assigned the impact factor of its publication year and its corresponding quartile according to Journal Citation Reports. The relationships between all of these parameters and the Spanish region, the gender and age of the interventional radiologists (IRs), and their connection to the university environment were also studied.

RESULTS

A total of 519 scientific articles from 247 SERVEI members working in 118 Spanish hospitals were included, an average of 0.3 articles per interventionist/year. Most of the manuscripts were published in impact journals (52.2%) and placed in the lowest quartile (Q4). Navarre, Aragon, and Catalonia were the regions with the highest publication rate during the period studied (1.7, 0.92, and 0.6 publications per interventionist/year, respectively). Only 57 articles (12.6%) were published in 11 of the 125 journals under the category of Radiology, Nuclear Medicine, and Medical Imaging according to JCR.

CONCLUSIONS

The scientific production of the Spanish IRs in the last 6 years is difficult to interpret. However, more than 50% of IRs published one article in the last 6 years. Finally, it would be advisable to repeat this study over a period of time in order to compare.

Global research trends of World Health Organization's top eight emerging pathogens

BACKGROUND

On December 8th, 2015, World Health Organization published a priority list of eight pathogens expected to cause severe outbreaks in the near future. To better understand global research trends and characteristics of publications on these emerging pathogens, we carried out this bibliometric study hoping to contribute to global awareness and preparedness toward this topic.

METHOD

Scopus database was searched for the following pathogens/infectious diseases: Ebola, Marburg, Lassa, Rift valley, Crimean-Congo, Nipah, Middle Eastern Respiratory Syndrome (MERS), and Severe Respiratory Acute Syndrome (SARS). Retrieved articles were analyzed to obtain standard bibliometric indicators.

RESULTS

A total of 8619 journal articles were retrieved. Authors from 154 different countries contributed to publishing these articles. Two peaks of publications, an early one for SARS and a late one for Ebola, were observed. Retrieved articles received a total of 221,606 citations with a mean ± standard deviation of 25.7 ± 65.4 citations per article and an h-index of 173. International collaboration was as high as 86.9%. The Centers for Disease Control and Prevention had the highest share (344; 5.0%) followed by the University of Hong Kong with 305 (4.5%). The top leading journal was Journal of Virology with 572 (6.6%) articles while Feldmann, Heinz R. was the most productive researcher with 197 (2.3%) articles. China ranked first on SARS, Turkey ranked first on Crimean-Congo fever, while the United States of America ranked first on the remaining six diseases. Of retrieved articles, 472 (5.5%) were on vaccine - related research with Ebola vaccine being most studied.

CONCLUSION

Number of publications on studied pathogens showed sudden dramatic rise in the past two decades representing severe global outbreaks. Contribution of a large number of different countries and the relatively high h-index are indicative of how international collaboration can create common health agenda among distant different countries.
