Failed extubation (FE), defined as reintubation 48 or 72 hours after planned extubation, occurs in a significant percentage of patients and is associated with a substantial burden of morbidity and mortality. This commentary reviews the literature describing FE rates and the clinical consequences of FE and proposes an 'optimal' rate of FE as well as avenues for future research.

Human respiratory infections caused by coronaviruses can range from mild to deadly. Although there are numerous studies on coronavirus disease 2019 (COVID-19), few have been published on its Omicron variant. In order to remedy this deficiency, this study undertook a bibliometric analysis of the publishing patterns of studies on the Omicron variant and identified hotspots. Automated transportation, environmental protection, improved healthcare, innovation in banking, and smart homes are just a few areas where machine learning has found use in tackling complicated problems. The sophisticated Scopus database was queried for papers with the term “Omicron” in the title published between January 2020 and June 2022. Microsoft Excel 365, VOSviewer, Bibliometrix, and Biblioshiny from R were used for a statistical analysis of the publications. Over the study period, 1917 relevant publications were found in the Scopus database. Viruses was the most popular in publications for Omicron variant research, with 150 papers published, while Cell was the most cited source. The bibliometric analysis determined the most productive nations, with USA leading the list with the highest number of publications (344) and the highest level of international collaboration on the Omicron variant. This study highlights scientific advances and scholarly collaboration trends and serves as a model for demonstrating global trends in Omicron variant research. It can aid policymakers and medical researchers to fully grasp the current status of research on the Omicron variant. It also provides normative data on the Omicron variant for visualization, study, and application.

Evidence from well-established theories of various disciplines manifests that, in the current technology-led world, continued professional development (CPD) of information professionals plays a paramount role in the uplift of institutions. CPD of university library professionals via e-learning programs leads to the implementation of user-centric-services through the initiation of emerging technological tools and the latest methods of service-delivery. The focus of this study is to shed light on the factors influencing e-learning for CPD of working librarians, challenges being encountered for e-learning adoption, and to propose the best practices for designing an efficient e-learning portfolio. For meeting the focused study-objectives, the authors applied PRISMA guidelines and procedures. An extensive search was conducted utilizing the world’s 16 leading e-databases and digital tools containing the most relevant core studies. Consequently, 30 impact factor research papers published in renowned databases were included through the identification, screening, eligibility, and inclusion process. Findings revealed that different factors—including organizational survival, continuous changes, adoption of emerging technologies, and professional growth—encouraged e-learning for CPD of information professionals. The study results showed that four main challenges—technical difficulties, lack of funds, reliance upon conventional models, and overwhelming work-load—were encountered for e-learning adoption. The authors proposed a framework for the development of an effective and efficient e-learning portfolio for building professional expertise among university librarians to support the organizational vision and mission statement. The recommended framework is based upon emergent categories and sub-categories extracted via thematic analysis of the existing empirical studies. This study has theoretical insights for the researchers through valuable addition in the body of literature and practical considerations for policy implementers to construct sustainable policies for devising e-learning programs to develop professional expertise in the university library workforce for attainment of value-added outcomes.

This study has conducted a meta-literature review examining the past, present and possible future trends of Fintech research using 360 selected articles published between 2006 and June 2020. Both quantitative and qualitative techniques were applied. In the quantitative approach, a bibliometric citation analysis using HistCite and VOSviewer software was conducted and the qualitative analysis covered the identification of four main research streams related to (i) Bitcoin and digital currency, (ii) crowdfunding, (iii) mobile payment, and (iv) blockchain. The study results highlight the most influential aspects of the FinTech literature, such as the leading countries, institutions, journals, authors, and articles. Suggestions for the potential future direction of FinTech literature have also been made.
