Inappropriate Citation of Retracted Articles in Anesthesiology and Intensive Care Medicine Publications.

BACKGROUND: Retracted articles represent research withdrawn from the existing body of literature after publication. Research articles may be retracted for several reasons ranging from honest errors to intentional misconduct. They should not be used as reliable sources, and it is unclear why they are cited occasionally by other articles. This study hypothesized that several mechanisms may contribute to citing retracted literature and aimed to analyze the characteristics of articles citing retracted literature in anesthesiology and critical care. METHODS: Using the Retraction Watch database, we retrieved retracted articles on anesthesiology and intensive care medicine up to August 16, 2021, and identified the papers citing these retracted articles. A survey designed to investigate the reasons for citing these articles was sent to the corresponding authors of the citing papers. RESULTS: We identified 478 retracted articles, 220 (46%) of which were cited at least once. We contacted 1297 corresponding authors of the papers that cited these articles, 417 (30%) of whom responded to our survey and were included in the final analysis. The median number of authors in the analyzed articles was five, and the median elapsed time from retraction to citation was 3 yr. Most of the corresponding authors (372, 89%) were unaware of the retracted status of the cited article, mainly because of inadequate notification of the retraction status in journals and/or databases and the use of stored copies. CONCLUSIONS: The corresponding authors were generally unaware of the retraction of the cited article, usually because of inadequate identification of the retracted status in journals and/or web databases and the use of stored copies. Awareness of this phenomenon and rigorous control of the cited references before submitting a paper are of fundamental importance in research.

The 100 most cited papers on retinal detachment: a bibliographic perspective.

The 100 most cited papers on retinal detachment (RD) were analysed using a bibliographic study. The bibliographic databases of the ISI Web of Knowledge were searched, limited to research articles published between 1965 and 2020 in peer-reviewed journals. The papers were ranked in order of number of citations since publication. Ninety of the 100 most cited papers on RD were published in 12 ophthalmology journals, with 74 of them published in American Journal of Ophthalmology (n=31), Ophthalmology (n=23), Archives of Ophthalmology (n=10) and Investigative Ophthalmology and Visual Science (n=10); the remaining 10 papers were published in 8 journals from other fields of medical research. All papers in the top 100 were published in English. The 100 most cited papers on RD originated from 12 different countries, with the majority (72 papers) originating from the USA. The 100 identified papers represent a mix of clinical trials and animal/laboratory studies. This bibliographic study provides a unique perspective and insight into some of the most influential contributions in RD understanding and management over the last 55 years.

Bibliography of published COVID-19 in children literature.

BACKGROUND: The COVID-19 pandemic is the biggest worldwide health challenge in this century. Research concerning the role of children in the spread of SARS-CoV-2, and investigating the clinical effects of infection in children, has been vital. This paper describes the publication trend for pertinent scientific literature relating to COVID-19 in children during the first 6 months of the pandemic. METHODS: A comprehensive search of preprint and published literature was conducted daily across four databases (PubMed, Scopus, Ovid-Embase and MedRXiv) between 1 January 2020 and 30 June 2020. Titles and abstracts were screened against predefined inclusion and exclusion criteria. FINDINGS: Over the study period, a total of 45 453 papers were retrieved, of which 476 met our inclusion criteria. The cumulative number of children described in included publications totalled (at most) 41 396. The median number of children per paper was 6 (IQR 1-33). Nearly one-third of papers (30.2%) reported on a single child, and a further 28.3% reported on between 1 and 9 children. Half of all the publications originated from Asia. INTERPRETATION: Our prospective bibliographic analysis of paediatric COVID-19 publications demonstrated a steady increase in the number of papers over time. Understanding and policy evolved with new information that was gathered over the course of the study period. However, over half of publications were individual case reports or small case series, which may have had a limited contribution to advancement of knowledge. During a pandemic, literature should be interpreted with great caution, and clinical/policy decisions should be continually reviewed in light of emerging evidence.

Os periódicos médicos brasileiros referenciam artigos nacionais? Um estudo transversal / Do Brazilian medical journals reference Brazilian articles? A cross-sectional study

Resumo Contexto A produção científica brasileira cresce de forma quantitativa e qualitativa a cada década. Entretanto, há uma desvalorização dos periódicos brasileiros demonstrada através da baixa quantidade de citações em comparação a textos de revistas internacionais, com justificativa subentendida de que há superioridade qualitativa de artigos estrangeiros. Objetivos Verificar a diferença entre o número de citações de periódicos nacionais e internacionais em três revistas brasileiras no período de 2016 a 2020. Métodos Foram analisados todos os artigos publicados na Revista do Colégio Brasileiro de Cirurgiões, no Jornal Vascular Brasileiro e na Acta Cirúrgica Brasileira no intervalo de 2016 a 2020. Os estudos selecionados tiveram suas referências avaliadas, sendo contabilizado o número total de citações e se eram provenientes de periódicos brasileiros ou de periódicos estrangeiros. Resultados Foram analisados 902 artigos, totalizando 23.394 referências, com média de 25,81 ± 8,59 por artigo. Nesse contexto, 2.680 (11,45%) eram nacionais, correspondentes a uma média de 2,95 ± 3,79 referências brasileiras por artigo. Conclusões Faz-se necessária a maior valorização dos periódicos brasileiros, em especial por parte dos pesquisadores nacionais e das instituições responsáveis pelo fomento da ciência.

Abstract Background The quantity and quality of Brazilian scientific output increases decade by decade. However, there is a tendency to undervalue Brazilian journals, illustrated by the low number of citations compared with texts in international journals, with the tacit justification that foreign articles are of superior quality. Objectives To investigate the differences in numbers of citations of Brazilian and international periodicals in three Brazilian journals from 2016 to 2020. Methods All articles published in the Journal of the Brazilian College of Surgeons, in the Jornal Vascular Brasileiro, and in Acta Cirúrgica Brasileira from 2016 to 2020 were analyzed. The references of these studies were analyzed, summing the total number of citations and classifying them as published in Brazilian or foreign journals. Results A total of 902 articles were analyzed, totaling 23,394 references, with a mean of 25.81 ± 8.59 references per article. Of these, 2,680 (11.45%) were Brazilian, equating to a mean of 2.95 ± 3.79 Brazilian references per article. Conclusions It is necessary to improve appreciation of Brazilian periodicals, especially among Brazilian researchers and institutions responsible for science funding.

The boundary-spanning mechanisms of Nobel Prize winning papers.

The breakthrough potentials of research papers can be explained by their boundary-spanning qualities. Here, for the first time, we apply the structural variation analysis (SVA) model and its affiliated metrics to investigate the extent to which such qualities characterize a group of Nobel Prize winning papers. We find that these papers share remarkable boundary-spanning traits, marked by exceptional abilities to connect disparate and topically-diverse clusters of research papers. Further, their publications exert structural variations on a scale that significantly alters the betweenness centrality distributions in existing intellectual space. Overall, SVA not only provides a set of leading indicators for describing future Nobel Prize winning papers, but also broadens our understanding of similar prize-winning properties that may have been overlooked among other regular publications.

Precisión de las referencias bibliográficas de los Trabajos de Fin de Grado en Enfermería / Accuracy of the bibliographic references used for Final Nursing Degree Projects

El grupo de los mejor calificados presentó un 17,05% de referencias correctas, frente al 9,13% de los peor calificados.Conclusiones: se encontró una baja precisión de las referencias en ambos grupos. Sin embargo, los trabajos con mayor calificación aportaron más referencias, mayor uso de revistas científicas, mayor concordancia con las normas de Vancouver y menor número de errores.(AU)

Objective: to identify the quality of the bibliography used by students in their 4th year of the Nursing Degree at the School of Nursing, Physiotherapy and Chiropody of the Universidad Complutense de Madrid.Method: the study was conducted through the selection and evaluation of information sources and references from journal articles in 26 Final Degree Projects (FDPs), in order to determine their conformity with the Vancouver Standards, because this is the quotation system more widely used in Health Sciences publications, and recommended by the professors responsible for education and follow-up of FDP groups.Results: out of 957 references in total, there was a selection of 604 (63.11%) journal articles, and 1.545 errors (2.55 per reference) were detected and classified. The group of those with the best scores presented 17.05% of correct references, vs. 9.13% for the group with the worst score.Conclusions: low accuracy in references was found in both groups. However, the projects with higher scores provided more references, higher use of scientific journals, higher agreement with Vancouver Standards, and lower number of errors.(AU)

Lantox-The Chinese Botulinum Toxin Drug-Complete English Bibliography and Comprehensive Formalised Literature Review.

In 1997, lanbotulinumtoxinA (LAN) was introduced in China. It is now available in Asia, Latin America and Eastern Europe under various brand names including Hengli®, Lantox®, Prosigne®, Lanzox®, Redux®, Liftox®, HBTX-A and CBTX-A. The literature on LAN is mostly published in Chinese language, restricting its international accessibility. We, therefore, wanted to generate a complete English bibliography of all LAN publications and then use it for a comprehensive formalised literature review. Altogether, 379 LAN publications (322 in Chinese and 57 in English) were retrieved from PubMed and Science and Technology Paper Citation Database. Indications covered are motor (257), glandular (16), pain (32) and aesthetics (48). Topics are neurological (250), aesthetic (48), paediatric (38), ophthalmological (18), urological (9), methodological (6), gastroenterological (5), ear, nose and throat (4) and surgical (1). Seventy-one publications are randomised controlled trials, forty-one publications are interventional studies and observational studies, fifteen publications are case studies, eighteen publications are reviews, and two publications are guidelines. LAN publications cover all relevant topics of BT therapy throughout a period of more than 20 years. This constitutes a publication basis resembling those of other BT drugs. None of the LAN publications presents data contradictory to those generated with other BT type-A drugs. LAN seems to have a similar efficacy and safety features when compared to onabotulinumtoxinA using a 1:1 LAN- onabotulinumtoxinA conversion ratio. Large controlled multicentre studies will become necessary for LAN's registrations in Europe and North America.

On the Road Again to Nursing's Future.

But how do we get there from here?

Article-level classification of scientific publications: A comparison of deep learning, direct citation and bibliographic coupling.

Classification schemes for scientific activity and publications underpin a large swath of research evaluation practices at the organizational, governmental, and national levels. Several research classifications are currently in use, and they require continuous work as new classification techniques becomes available and as new research topics emerge. Convolutional neural networks, a subset of "deep learning" approaches, have recently offered novel and highly performant methods for classifying voluminous corpora of text. This article benchmarks a deep learning classification technique on more than 40 million scientific articles and on tens of thousands of scholarly journals. The comparison is performed against bibliographic coupling-, direct citation-, and manual-based classifications-the established and most widely used approaches in the field of bibliometrics, and by extension, in many science and innovation policy activities such as grant competition management. The results reveal that the performance of this first iteration of a deep learning approach is equivalent to the graph-based bibliometric approaches. All methods presented are also on par with manual classification. Somewhat surprisingly, no machine learning approaches were found to clearly outperform the simple label propagation approach that is direct citation. In conclusion, deep learning is promising because it performed just as well as the other approaches but has more flexibility to be further improved. For example, a deep neural network incorporating information from the citation network is likely to hold the key to an even better classification algorithm.
