Myocardial fibrosis in repaired tetralogy of Fallot; Predicting ventricular arrhythmia and sudden cardiac death

We are faced with new challenges in the growing population of adult survivors with repaired tetralogy of Fallot (rTOF). The risk of premature death persists and drives eager pursuit for the accurate identification of patients at high-risk of malignant ventricular tachycardia (VT) and sudden cardiac death (SCD). It is previously known that inducible VT predicts mortality in rTOF patients. We show that the burden of right ventricular (RV) late gadolinium enhancement (LGE) defined fibrosis > 25cm3 quantified by high-sensitivity 3D LGE can predict inducible VT as a proxy endpoint for mortality. Patients with minimal RV LGE < 10cm3 were extremely unlikely to have inducible VT suggesting those with minimal RVLGE avoid an invasive study. In a prospective study of 550 rTOF patients, a high-risk subgroup of patients with a 4.4% annualised risk of death and 3.7% annualised risk of life-threatening VT/SCD were identified. RVLGE was a strong predictor of outcome. We demonstrated how RVLGE can be integrated with other independent predictors into weighted risk scores ready for clinical use. Diffuse fibrosis defined by RV T1 shows promise as a subtle biomarker of adverse remodelling. An imbalance in the expression of fibrosis biomarkers suggests that a state of high-collagen turnover exists and correlates with adverse remodelling. In conclusion, myocardial fibrosis plays a central role in predicting death and malignant VT in rTOF. This work identifies biomarkers to help risk stratify and enable more personalised and targeted care in the life-long follow up of adult rTOF patients.Open Acces

Designing Data Spaces

This open access book provides a comprehensive view on data ecosystems and platform economics from methodical and technological foundations up to reports from practical implementations and applications in various industries. To this end, the book is structured in four parts: Part I “Foundations and Contexts” provides a general overview about building, running, and governing data spaces and an introduction to the IDS and GAIA-X projects. Part II “Data Space Technologies” subsequently details various implementation aspects of IDS and GAIA-X, including eg data usage control, the usage of blockchain technologies, or semantic data integration and interoperability. Next, Part III describes various “Use Cases and Data Ecosystems” from various application areas such as agriculture, healthcare, industry, energy, and mobility. Part IV eventually offers an overview of several “Solutions and Applications”, eg including products and experiences from companies like Google, SAP, Huawei, T-Systems, Innopay and many more. Overall, the book provides professionals in industry with an encompassing overview of the technological and economic aspects of data spaces, based on the International Data Spaces and Gaia-X initiatives. It presents implementations and business cases and gives an outlook to future developments. In doing so, it aims at proliferating the vision of a social data market economy based on data spaces which embrace trust and data sovereignty

Oasis from Learn-to-Earn: Adult, Working-Class, Liberal Arts Graduates Make Meaning of their Learning Careers at Harvard

The purpose of this study was to learn from 18 adult students, all of whom grew-up working class and many of whom were living working-class lives as adults, the meaning of returning to school and earning a liberal arts degree from an open-enrollment program. Harvard Extension School (HES), which is part of a selective, elite institution: Harvard University. The educational research in the US is sparse on adult, working-class, liberal arts, students. Indeed, these students\u27 experiences go mostly undocumented due to the agreed upon conclusion that adult students, in general, and working-class students, in particular, are more interested in job training than liberal arts learning. From this qualitative, narrative inquiry, I learned that institutional adult education is often about validation and attempting to silence mounting feelings of marginality and deprivation (Hooper & Osborn, 1975) much more than about job training. It is about becoming somebody (Luttrell, 1997; Wexler, 1999) in one\u27s own eyes and in the eyes of others. As Maxine Greene (1990) would conclude, it is also about looking like Melville\u27s water-gazers, for something more out of life. But instead of turning to the sea and nature, these working-class adult students turned to books and culture— humanistic education— to break from the everyday routine and to reassure themselves, through the more difficult pleasures of the mind, that there is more to life than just work. Finally, it is about a liberal arts education exerting its academic influence by helping working-class adults claim intellectual identities and warm up (Deil, 2001) their academic expectations. But for some participants, it was about finding themselves, using Bourdieu\u27s (1999) language, outcasts on the inside, holders of a somewhat elite liberal arts degree, but due to the open-enrollment, second-chance nature of the education, not truly benefiting from higher education\u27s standard economic, social, or cultural capital. This study is about the intellectual joys as well as the emotional hurts of liberal arts education for working-class adults

Playing the Judge: Law and Imperial Messaging in Severan Rome

This dissertation analyzes the interplay between imperial messaging or self-representation and legal activity in the Roman Empire under the Severan dynasty. I discuss the unusual historical circumstances of Septimius Severus’ rise to power and the legitimacy crises faced by him and his successors, as well as those same emperors’ control of an increasingly complex legal bureaucracy and legislative apparatus. I describe how each of the four Severan rulers—Septimius Severus, Caracalla, Elagabalus, and Severus Alexander—employed different approaches to imperial legislation and adjudication in accordance with their idiosyncratic self-presentation and messaging styles, as well as how other actors within Roman legal culture responded to Severan political dynamics in their own work. In particular, this dissertation is concerned with a particularly—and increasingly—urgent problem in Roman elite political culture; the tension between theories of imperial power that centered upon rulers’ charismatic gifts or personal fitness to rule, and a more institutional, bureaucratized vision that placed the emperor at the center of broader networks of administrative control. While these two ideas of the Principate had always coexisted, the Severan period posed new challenges as innovations in imperial succession (such as more open military selection of emperors) called earlier legitimation strategies into question. I posit that Roman law, with its stated tendency towards regularized, impersonal processes, was a language in which the Severan state could more easily portray itself as a bureaucratic institution that might merit deference without a given leader being personally fit to rule. This dissertation begins by discussing the representational strategy of Septimius Severus, who deployed traditional imperial messaging tropes in strikingly legalistic forms. I then explore how this model of law as a venue for or language of state communication might explain otherwise idiosyncratic features of the constitutio Antoniniana, an edict promulgated by Septimius Severus’ son Caracalla that granted citizenship to all free inhabitants of the Empire. I next discuss two unusual features of the corpus of rescripts issued by Severus Alexander, the last Severan emperor: specifically, the relabeling of rescripts issued by Elagabalus, Alexander’s cousin and predecessor, as products of Alexander’s reign; and the idiosyncratic frequency with which rescripts issued under Alexander’s authority cite prior imperial (and particularly Severan) precedent. Finally, I discuss how jurists responded to Severan (and particularly late Severan) political and legal culture: late Severan jurists are particularly inclined to justify their legal decisionmaking in terms of the desirable consequences of a given decision’s universal promulgation, and similarly likely to justify their opinions by citing to an impersonal ‘imperial authority’ rather than to named figures. I argue that these changes reflect both state and scholarly attempts to wrestle with increasingly unstable imperial selection processes, and to articulate a vision of Roman governance that might function in the new world of the third century C.E
