No full textCitations and metrics of journals discontinued from Scopus for publication concerns: the GhoS(t)copus Project
Full text linkBackground: Scopus is a leading bibliometric database. It contains a large part of the articles cited in peer-reviewed publications . The journals included in Scopus are periodically re-evaluated to ensure they meet indexing criteria and some journals might be discontinued for 'publication concerns'. Previously published articles may remain indexed and can be cited. Their metrics have yet to be studied. This study aimed to evaluate the main features and metrics of journals discontinued from Scopus for publication concerns, before and after their discontinuation, and to determine the extent of predatory journals among the discontinued journals. Methods: We surveyed the list of discontinued journals from Scopus (July 2019). Data regarding metrics, citations and indexing were extracted from Scopus or other scientific databases, for the journals discontinued for publication concerns. Results: A total of 317 journals were evaluated. Ninety-three percent of the journals (294/317) declared they published using an Open Access model. The subject areas with the greatest number of discontinued journals were Medicine (52/317; 16%), Agriculture and Biological Science (34/317; 11%), and Pharmacology, Toxicology and Pharmaceutics (31/317; 10%). The mean number of citations per year after discontinuation was significantly higher than before (median of difference 16.89 citations, p<0.0001), and so was the number of citations per document (median of difference 0.42 citations, p<0.0001). Twenty-two percent (72/317) were included in the Cabell's blacklist. The DOAJ currently included only 9 journals while 61 were previously included and discontinued, most for 'suspected editorial misconduct by the publisher'. Conclusions: Journals discontinued for 'publication concerns' continue to be cited despite discontinuation and predatory behaviour seemed common. These citations may influence scholars' metrics prompting artificial career advancements, bonus systems and promotion. Countermeasures should be taken urgently to ensure the reliability of Scopus metrics for the purpose of scientific assessment of scholarly publishing at both journal- and author-level
High flow nasal therapy in perioperative medicine: from operating room to general ward
Full text linkBACKGROUND: High flow nasal therapy (HFNT) is a technique in which humidified and heated gas is delivered to the airways through the nose via small nasal prongs at flows that are higher than the rates generally applied during conventional oxygen therapy. The delivered high flow rates combine mixtures of air and oxygen and enable different inspired oxygen fractions ranging from 0.21 to 1. HFNT is increasingly used in critically ill adult patients, especially hypoxemic patients in different clinical settings. MAIN BODY: Noninvasive ventilation delivers positive pressure (end-expiratory and inspiratory pressures or continuous positive airway pressure) via different external interfaces. In contrast, HFNT produces different physiological effects that are only partially linked to the generation of expiratory positive airway pressure. HFNT and noninvasive ventilation (NIV) are interesting non-invasive supports in perioperative medicine. HFNT exhibits some advantages compared to NIV because HFNT is easier to apply and requires a lower nursing workload. Tolerance of HFNT remains a matter of intense debate, and it may be related to selected parameters. Patients receiving HFNT and their respiratory patterns should be closely monitored to avoid delays in intubation despite correct oxygenation parameters. CONCLUSION: HFNT seems to be an interesting noninvasive support in perioperative medicine. The present review provides anesthesiologists with an overview of current evidence and practical advice on the application of HFNT in perioperative medicine in adult patients
