Percutaneous Recanalization of Chronic Total Occlusions : 2019 Consensus Document from the EuroCTO Club
2019
Since its inception in December 2006, the EuroCTO Club has strived to provide the framework for state-of-the-art chronic total occlusion (CTO) percutaneous coronary intervention (PCI) in Europe and nearby regions. Among its initiatives, the EuroCTO Club has published a set of recommendations regarding the technical aspects of CTO PCI, whose last edition dates to 2012. The EuroCTO Club consensus document discusses CTO PCI clinical indications, techniques and equipment use, as well as the qualifications of operators/centres. Given the considerable amount of progress made by this subspecialty in recent years, there is a need for an updated document that includes data from recent clinical trial…
Radiation Exposure for Percutaneous Interventions of Chronic Total Coronary Occlusions in a Multicenter Registry: The Influence of Operator Variabili…
2021
Aims. Radiation exposure is a limiting factor for percutaneous coronary interventions (PCI) of chronic total coronary occlusion (CTO) lesions. This study was designed to analyze changes in patient radiation dose for CTO-PCI and parameters associated with radiation dose. Methods and Results. We analyzed a cohort of 12,136 procedures performed by 23 operators between 2012 and 2017 from the European Registry of CTO-PCI. Radiation exposure was recorded as air kerma (AK) and dose area product (DAP). A dose rate index (DRI) was calculated as AK per fluoroscopy time to normalize for individual differences in fluoroscopy time. The lesion complexity increased from Japanese-CTO (J-CTO) score of 2.19 …
On the slabbing of stones throughdiamond wire cutting
2010
Diamond wires are usually used in the cutting operations aimed to obtain slabs of stones. This tool consists of a steel cable on which are mounted annular metal–diamond pearls. The use of this technology expanded all over the world because of its advantages on other slabbing techniques as both technical and economical aspects are considered. It should be observed that with this technology wear phenomena must be properly monitored in order to obtain the best process conditions. Inthis article, thediamondwire cutting operation is investigated, highlighting the process mechanics and the wear phenomena occurring in the used tools. Furthermore, a modified version of the tool itself is proposed w…
Il contrasto al traffico di esseri umani fra modelli normativi e risultati applicativi
2016
La lotta al traffico di esseri umani è ormai al centro dell’agenda politica globale. Eppure, esiste una forbice molto ampia tra le ambizioni dei modelli normativi finora elaborati e gli scarsi risultati pratici raggiunti: le condanne per tali reati, infatti, continuano ad essere poche in pressoché tutti gli ordinamenti. L’Autore, preliminarmente, esamina la più recente normativa internazionale ed europea in argomento, nonché le più importanti pronunce della Corte Edu circa il divieto di schiavitù previsto dall’art. 4 della Cedu. Nel tentativo di apportare un contributo all’individuazione delle ragioni di un tale deficit di risultati, e di proporre potenziali correttivi, sono poi evidenziati…
Zabieg medycyny estetycznej w przypadku małoletniego dziecka bez zgody sądu rodzinnego a odpowiedzialność prawnokarna
2017
This article refers to criminal liability for performing aesthetic medicine treatment in a form of plastic surgery without patient’s consent, substitute consent (including collective) or substitute consent of Family Court. Article presents the current state of law in this respect and the correlation between applicable regulations of various branches of law and lex generalis regulations that deal with this issue, i.e. aesthetic medicine treatment.The author evaluates and describes the legal issues related with aesthetic medicine, including the patient’s consent, extended disclosure obligation as well as the ground for statutory liability for committing a prohibited act that is described and …
[Optimization of systemic treatments for chronic plaque psoriasis. Recommendations for switching and transitioning.]
2014
The aim of this study was to provide practical recommendations for optimizing the use of conventional and biological systemic treatments for moderate-severe chronic plaque psoriasis, particularly in case of transitioning and switching.A total number of 147 dermatologists from 33 different countries including Italy achieved consensus in providing practical recommendations for the use of conventional and biological treatments for moderate to severe psoriasis based on systematic literature review and/or expert opinion.In general, the continuous treatment regimen should be preferred in order to achieve a complete and long-term control of psoriasis. However, the treatment could be stopped or the…
Stealth dicing with Bessel beams and beyond
2016
In the context of laser cutting of transparent materials, we investigate glass cleaving with Bessel beams and report that a modification of the beam with 3 main lobes drastically enhances cleavability and reduces defects.
Supporting Agile Development by Facilitating Natural User Interaction with Executable Formal Specifications
2011
Agile development benefits from fast feedback from various stakeholders. If implemented in a suitable way, formal methods can enhance the agile development process. With an executable formal specification, it is possible to analyse and simulate the behaviour of the target system before it is being built. However, for the users' and developers' natural participation in the development process, it is necessary to use a real end-user interface and bind it to the execution environment being used in the simulations and animations. This requires, though, that the execution model used to simulate the specification is appropriately changed to facilitate the use of these user interfaces. The authors…
Remote Attestation of Software and Execution-Environment in Modern Machines
2015
The research on network security concentrates mainly on securing the communication channels between two endpoints, which is insufficient if the authenticity of one of the endpoints cannot be determined with certainty. Previously presented methods that allow one endpoint, the authentication authority, to authenticate another remote machine. These methods are inadequate for modern machines that have multiple processors, introduce virtualization extensions, have a greater variety of side effects, and suffer from nondeterminism. This paper addresses the advances of modern machines with respect to the method presented by Kennell. The authors describe how a remote attestation procedure, involving…
Support vector machine integrated with game-theoretic approach and genetic algorithm for the detection and classification of malware
2013
Abstract. —In the modern world, a rapid growth of mali- cious software production has become one of the most signifi- cant threats to the network security. Unfortunately, wides pread signature-based anti-malware strategies can not help to de tect malware unseen previously nor deal with code obfuscation te ch- niques employed by malware designers. In our study, the prob lem of malware detection and classification is solved by applyin g a data-mining-based approach that relies on supervised mach ine- learning. Executable files are presented in the form of byte a nd opcode sequences and n-gram models are employed to extract essential features from these sequences. Feature vectors o btained are…
