    The presence of a patent foramen ovale (PFO) is implicated in the pathogenesis of a number of medical conditions; however, the subject remains controversial and no official statements have been published. This interdisciplinary paper, prepared with involvement of eight European scientific societies, aims to review the available trial evidence and to define the principles needed to guide decision making in patients with PFO. In order to guarantee a strict process, position statements were developed with the use of a modified grading of recommendations assessment, development, and evaluation (GRADE) methodology. A critical qualitative and quantitative evaluation of diagnostic and therapeutic procedures was performed, including assessment of the risk/benefit ratio. The level of evidence and the strength of the position statements of particular management options were weighed and graded according to predefined scales. Despite being based often on limited and non-randomised data, while waiting for more conclusive evidence, it was possible to conclude on a number of position statements regarding a rational general approach to PFO management and to specific considerations regarding left circulation thromboembolism. For some therapeutic aspects, it was possible to express stricter position statements based on randomised trials. This position paper provides the first largely shared, interdisciplinary approach for a rational PFO management based on the best available evidence

    AI-Based Media Coding Standards

    Moving Picture, Audio and Data Coding by Artificial Intelligence (MPAI) is the first standards organization to develop data coding standards that have artificial intelligence (AI) as their core technology. MPAI believes that universally accessible standards for AI-based data coding can have the same positive effects on AI as standards had on digital media. Elementary components of MPAI standards–AI modules (AIMs)–expose standard interfaces for operation in a standard AI framework (AIF). As their performance may depend on the technologies used, MPAI expects that competing developers providing AIMs will promote horizontal markets of AI solutions that build on and further promote AI innovation. Finally, the MPAI framework licences (FWLs) provide guidelines to intellectual property right (IPR) holders facilitating the availability of compatible licenses to standard users

    INTRODUCTION: Despite encouraging short-term and mid-term results, transcatheter aortic valve implantation (TAVI) interventions are still burdened from high rates of adverse events, stressing the need for accurate predictive risk instruments. We compared available surgical risk scores to describe unfavorable outcomes after TAVI. METHODS: The Age, Creatinine, and Ejection fraction (ACEF) score, the logistic Euroscore, and the Society of Thoracic Surgeons Mortality score (STS) were appraised for their independent power of prediction and for their accuracy (C-index) to predict 30-day and medium-term mortality, according to the Valve Academic Research Consortium. RESULTS: Nine hundred and sixty-two patients were included. All the scores demonstrated a moderate positive correlation. The closest correlation was observed between the STS score and Euroscore. After logistic regression analysis, STS score and Logistic Euroscore provided independent prediction for short-term all-cause mortality [P = 0.02, odds ratio (OR) 1.1; 95% confidence interval (CI) 1.06-1.31 and P = 0.027, OR 1.03; 95% CI 1.01-1.405]. For in-hospital complications, only STS score performed significantly (P = 0.005, OR 1.05; 95% CI 1.01-1.06). ACEF, Euroscore, and STS score showed low accuracy for 30-day all-cause mortality (area under the curve 0.6, 0.44-0.75; vs. 0.53, 0.42-0.61; vs. 0.62, 0.52-0.71, respectively), whereas STS score performed better for in-hospital complications (0.59, 0.55-0.64). Moreover, after Cox-multivariate adjustments, only ACEF score was near to significance to predict all-cause mortality at mid-term (OR 1.7; 0.8-2.9; P = 0.058), showing the highest accuracy (0.63, 0.55-0.71). CONCLUSION: In TAVI patients, ACEF score, STS score and Logistic Euroscore provided only a moderate correlation and a low accuracy both for 30-day and medium-term outcomes. Dedicated scores are needed to properly tailor time and kind of approach

    European position paper on the management of patients with patent foramen ovale. Part II - Decompression sickness, migraine, arterial deoxygenation syndromes and select high-risk clinical conditions

    Patent foramen ovale (PFO) is implicated in the pathogenesis of a number of medical conditions but to date only one official position paper related to left circulation thromboembolism has been published. This interdisciplinary paper, prepared with the involvement of eight European scientific societies, reviews the available evidence and proposes a rationale for decision making for other PFO-related clinical conditions. In order to guarantee a strict evidence-based process, we used a modified grading of recommendations, assessment, development, and evaluation (GRADE) methodology. A critical qualitative and quantitative evaluation of diagnostic and therapeutic procedures was performed, including assessment of the risk/benefit ratio. The level of evidence and the strength of the position statements were weighed and graded according to predefined scales. Despite being based on limited and observational or low-certainty randomised data, a number of position statements were made to frame PFO management in different clinical settings, along with suggestions for new research avenues. This interdisciplinary position paper, recognising the low or very low certainty of existing evidence, provides the first approach to several PFO-related clinical scenarios beyond left circulation thromboembolism and strongly stresses the need for fresh high-quality evidence on these topics
