Multimodality imaging in arrhythmogenic cardiomyopathy
Authors: Tapoi Laura , Clement Alexandra , Radu Rodica , Sascau Radu 
Published: April 2021

Abstract
Arrhythmogenic cardiomyopathy, as it has been recently redefined, is characterized by progressive myocyte loss with fibrosis and fat infiltration of the myocardium, which finally leads to a broad clinical spectrum ranging from heart failure symptoms to sudden cardiac death. The diagnosis of arrhythmogenic cardiomyopathy is challenging particularly because of its heterogeneity in presentation, which varies from focal right ventricular involvement to biventricular or prominent left ventricular phenotype. In the past decades, the development of new electrocardiographic and imaging diagnostic criteria for arrhythmogenic cardiomyopathy constituted an important area of research and resulted in the elaboration of the Padua criteria. However, even with the widespread availability of modern imaging techniques, there is still a lack of awareness in the health care community and this pathology persist in being under- or misdiagnosed. Given the limited indication of endomyocardial biopsy for the diagnosis of arrhythmogenic cardiomyopathy, one can conclude that the progress that has been made in the last few years in the multimodality imaging field is of utmost importance for the early detection and proper treatment of patients with arrhythmogenic cardiomyopathy, providing valuable prognostic information.

Abstract
AL (light chain) amyloidosis is a life threatening disease. Untreated patients with involvement of the heart, a condition known as cardiac amyloidosis (CA), tend to have the most rapid disease progression and worst prognosis. Therefore, it is essential to early recognize the signs of symptoms of CA, and to identify the affected individuals with readily available non-invasive tests, as timely therapy can prolong life. Different imaging tests are used to diagnose and stratify the risk of the disease noninvasively, and to follow-up of the disease course and response to therapy. In this light, we present a case of a woman with cardiovascular risk factors, initially admitted for typical angina and decompensated heart failure (HF), who was later diagnosed with AL amyloidosis with cardiac involvement, by using multimodality imaging assessment in a step-by-step fashion. This changed completely the prognosis of the patient. Timely chemotherapy and stem cell transplantation led to an improvement in clinical status, biomarkers, and in a regression of amyloid myocardial infiltration showed by imaging.

Abstract
Myxomatous mitral valve disease (MVD) is a common disorder in which the entire mitral valve apparatus seems to be involved. Mitral valve repair is nowadays the method of choice for the correction of mitral regurgitation but the optimal shape and flexibility of the annuloplasty ring remain controversial. Considering that myxomatous MVD covers a wide spectrum from limited fibro-elastic deficiency to extensive Barlow disease, we presume that the mitral annulus morphological and functional changes are likely different in different types of myxomatous MVD. We analyze the 3-dimensional geometry and the dynamics of the mitral annulus in 110 patients with significant mitral regurgitation due to different types of myxomatous mitral valve disease and 40 normal subjects using 3D transesophageal echocardiography. The mitral annulus differs in patients with limited MVD, extensive MVD and in normal controls in terms of size, shape, and dynamics Patients with limited MVD have larger, flatter, dysfunctional and more mobile mitral annulus compared to normal, while patients with extensive MVD have even larger, flatter and more dysfunctional mitral annulus, with reduced mobility. The non-planar dynamics has different patterns during systole, according to the extension of MV disease. Our data may be important for the appropriate choose of annuloplasty mitral annulus in mitral valve repair, the current trend being to choose the ring according to the underlying pathology.
Acute symptomatic seizures and ventricular fibrillation - a multimodality approach to a rare complication of myocardial infarction. Case report
Authors: Stefan Miruna Florina , Magda Stefania Lucia 
Published: April 2021

Abstract

Background
6–8% of patients with acute myocardial infarction still develop ventricular arrhythmias (VA), although their incidence has lowered due to prompt antiischemic treatment. VA might determine sometimes acute symptomatic seizures.

Case report
A 44-year old male was admitted to our unit with acute inferior myocardial infarction. Emergency coronary angiography was performed and revealed acute occlusion of the right coronary artery. The procedure was complicated by coronary dissection, which was sealed, with good final results. After admission in the acute coronary unit, the patient developed ventricular fibrillation. He was successfully resuscitated, but developed ongoing tonic-clonic seizures, terminated after intravenous administration of several anticonvulsivant drugs. We investigated the patient for epilepsy and for other pathologies that could explain both the VA and the seizures. All investigations were within normal range.

Conclusion
Differential diagnosis between hypoxic and epileptic seizures is difficult and important, because it further influences patient management. Cardiac arrhythmias are a rare precipitating factor for acute symptomatic seizures, due to hypotension-induced cerebral hypoxemia. Our case illustrates the value of a multimodal approach of rare complication of a myocardial infarction.

Abstract. Understanding the dependencies of the terrestrial carbon and water cycle with meteorological conditions is a prerequisite to anticipate their behaviour under climate change conditions. However, terrestrial ecosystems and the atmosphere interact via a multitude of variables across temporal and spatial scales. Additionally these interactions might differ among vegetation types or climatic regions.
Today, novel algorithms aim to disentangle the causal structure behind such interactions from empirical data. The estimated causal structures can be interpreted as networks, where nodes represent relevant meteorological variables or land-surface fluxes and the links represent the dependencies among them (possibly including time lags and link strength). Here we derived causal networks for different seasons at 119 eddy covariance flux tower observations in the FLUXNET network. We show that the networks of biosphere–atmosphere interactions are strongly shaped by meteorological conditions. For example, we find that temperate and high-latitude ecosystems during peak productivity exhibit biosphere–atmosphere interaction networks very similar to tropical forests. In times of anomalous conditions like droughts though, both ecosystems behave more like typical Mediterranean ecosystems during their dry season. Our results demonstrate that ecosystems from different climate zones or vegetation types have similar biosphere–atmosphere interactions if their meteorological conditions are similar. We anticipate our analysis to foster the use of network approaches, as they allow for a more comprehensive understanding of the state of ecosystem functioning. Long-term or even irreversible changes in network structure are rare and thus can be indicators of fundamental functional ecosystem shifts.

Abstract. Plant phenology plays a fundamental role in land–atmosphere interactions, and its variability and variations are an indicator of climate and environmental changes.
For this reason, current land surface models include
phenology parameterizations and related biophysical and biogeochemical processes.
In this work, the climatology of the beginning and end of the growing season, simulated by the land component of seven state-of-the-art European Earth system models participating in the CMIP6, is evaluated globally against satellite observations. The assessment is performed using the vegetation metric leaf area index and a recently developed approach, named four growing season types.
On average, the land surface models show a 0.6-month delay in the growing season start, while they are about 0.5 months earlier in the growing season end. The difference with observation tends to be higher in the Southern Hemisphere compared to the Northern Hemisphere.
High agreement between land surface models and observations is exhibited in areas dominated by broadleaf deciduous trees, while high variability is noted in regions dominated by broadleaf deciduous shrubs.
Generally, the timing of the growing season end is accurately simulated in about 25 % of global land grid points versus 16 % in the timing of growing season start.
The refinement of phenology parameterization can lead to better representation of vegetation-related energy, water, and carbon cycles in land surface models, but plant phenology
is also affected by plant physiology and soil hydrology processes.
Consequently, phenology representation and, in general, vegetation
modelling is a complex task, which still needs further improvement, evaluation, and multi-model comparison.

Abstract. We propose a multiscale approach for coupling multi-physics processes across the scales. The physics is based on discrete phenomena, triggered by local thermo-hydro-mechano-chemical (THMC) instabilities, that cause cross-diffusion (quasi-soliton) acceleration waves. These waves nucleate when the overall stress field is incompatible with accelerations from local feedbacks of generalized THMC thermodynamic forces that trigger generalized thermodynamic fluxes of another kind. Cross-diffusion terms in the 4×4 THMC diffusion matrix are shown to lead to multiple diffusional P and S wave equations as coupled THMC solutions. Uncertainties in the location of meso-scale material instabilities are captured by a wave-scale correlation of probability amplitudes. Cross-diffusional waves have unusual dispersion patterns and, although they assume a solitary state, do not behave like solitons but show complex interactions when they collide. Their characteristic wavenumber and constant speed define mesoscopic internal material time–space relations entirely defined by the coefficients of the coupled THMC reaction–cross-diffusion equations. A companion paper proposes an application of the theory to earthquakes showing that excitation waves triggered by local reactions can, through an extreme effect of a cross-diffusional wave operator, lead to an energy cascade connecting large and small scales and cause solid-state turbulence.

The relevance of the study is determined by the fact that the processes of reproduction of human capital with the most recent quality characteristics, skills, and competencies are actively evolving in the context of the digital transformation of the economy. The goal of the article is to study transformation processes and to identify the main characteristics of the reproduction of human capital in the context of digital and technological transformation. The empirical base of the study is represented by the data from the Federal State Statistics Service of the Russian Federation, as well as from reports and statistical books of the National Research University Higher School of Economics on the development of human capital and digital economy in Russia. The methodological basis of the study includes a systemic and holistic approach, retrospective, evolutionary, monographic, and comparative logical analysis, content analysis of scientific literature and empirical sources, as well as methods of generalization and systematization. The stages of the evolution of human capital have been identified and described in the course of the study; a model of the evolution of the human capital structure in the digital economy has been formed, including its traditional and new characteristics; the physical, intellectual, socioindustrial, and digital (technological) components of the reproduction of human capital in the Russian Federation and the Central Federal District have been analyzed. The conclusion has been drawn of the need to transform the mechanisms of the reproduction of human capital for the formation of new digital and technological competencies and for overcoming the divergence of technogenesis and anthropogenesis.

Grenzeloze problemen bij grensoverschrijdende arbeid
Indien een werknemer in een ander land werkzaamheden verricht dan waar hij zijn dienstverband heeft, bevindt de (reikwijdte van zijn) arbeidsovereenkomst zich niet langer onder de glazen stolp van één nationaal rechtsstelsel. De stap over de grens maakt dat de arbeidsovereenkomst raakvlakken vertoont met meer landen, die elk hun eigen normen, waarden en regels kennen inzake het arbeidsrecht. Die eigenheid van het nationale arbeidsrecht maakt de vraag naar het toepasselijke recht relevant. Dat het antwoord hierop niet altijd eenduidig is te geven, blijkt uit de zaak die heeft geleid tot het arrest van de Hoge Raad van 3 februari 2012. De Hoge Raad stelt in dit arrest twee prejudiciële vragen aan het Hof van Justitie over de uitleg van het EVO-Verdrag indien sprake is van een permanente tewerkstelling in het ene land terwijl alle overige omstandigheden op een nauwe verbondenheid met een ander land wijzen. In deze bijdrage bespreekt de auteur de discussie tussen partijen over het toepasselijke recht in het licht van het EVO-Verdrag (en de Rome I-Verordening). Speciale aandacht gaat uit naar de betekenis van de fundamentele verdragsvrijheid inzake het vrije werknemersverkeer.

De waarden van het (arbeids)recht: liber amicorum voor prof. mr. Paul F. van der Heijden
De bijdragenbundel De waarden van het (arbeids)recht bevat enkele reflecties over de grondslagen of basiswaarden en over de functies en grenzen van het (arbeids)recht. De bundel blikt terug op het preadvies dat Van der Heijden en Noordam in 2001 rond hetzelfde thema uitwerkten vanuit de vraag waartoe het grondslagendebat tot dusver heeft geleid. Wat is de staat van de in het preadvies geïdentificeerde basiswaarden en welke invulling krijgen ze in de huidige sociaal-rechtelijke context? Acht auteurs nemen het woord over een selectie van vijf van de genoemde basiswaarden, over de ‘sociaal-rechtelijke variabele’ van de wederkerigheid en over de functies van het arbeidsrecht. Heerma van Voss en Verhulp besluiten het geheel ten slotte met enkele kritische slotbeschouwingen.
De rechtsstaat en het geld

De rechtsstaat en het geld
De auteurs van deze bijdrage signaleren dat in Polen en Hongarije de rechtsstaat wankelt. Nu is de rechtsstatelijke situatie in Polen en Hongarije weliswaar niet te vergelijken met die van ons land, toch is ook die niet onaantastbaar. Kwetsbaar in dit opzicht is de financiering van de rechtspraak. Zo kan de principiële vraag worden gesteld of de onafhankelijkheid van de derde staatsmacht wel voldoende is geborgd nu deze binnen de begroting van de uitvoerende macht valt, in casu het ministerie van Justitie en Veiligheid. Het huidige financieringssysteem knelt überhaupt. Voor deze bijdrage is vooral relevant dat het financieringssysteem niet voorziet in een adequaat budget voor de noodzakelijke innovatie. Die noodzaak is er voortdurend en zeker nu.

El Mediterráneo es una de las rutas migratorias más mortíferas del mundo y se ha convertido una vez más en centro de la polémica en relación a la actuación del buque humanitario Open Arms. Este buque, tras rescatar migrantes del mar, estuvo en travesía durante diecinueve días, bloqueado institucionalmente y envuelto en disputas diplomáticas en la Unión Europea. Como reacción, la ciudadanía, distintos actores sociales y la propia ONG Open Arms hicieron uso de Twitter para intercambiar información y expresar opiniones y sentimientos en relación con el fenómeno migratorio. En este artículo se analizan pautas de conectividad e interacción de los usuarios de Twitter en torno al hashtag #Openarms. Tras recoger muestras masivas de tuits con técnicas de extracción, se identificaron los actores sociales con mayor liderazgo mediante análisis de redes sociales. Se han detectado comunidades por medio del algoritmo de modularidad, cuyo contenido ha sido interpretado mediante netnografía. Los resultados evidencian cómo los usuarios de Twitter tienden a congregarse con quienes comparten sus mismas creencias, formándose las denominadas cámaras eco. La interacción en base a este suceso despertó estados emocionales colectivos que dieron lugar a burbujas filtro que potenciaron la desinformación y la polarización entre comunidades.

The research focuses on the high temperature oxidation resistance of martensitic heat-resistant steel. A new type of martensitic heat-resistant steel was developed with the addition of Al and Cu, and the oxidation behavior of the new martensitic heat-resistant steel at 650 °C and 700 °C was analyzed. The high temperature oxidation kinetics curves of new martensitic heat-resistant steel at 650 °C and 700 °C were determined and plotted by cyclic oxidation experiment and discontinuous weighing method. XRD technique was applied to qualitatively analyze the surface oxide of the material after oxidation. The surface and cross-section morphology of the material were observed by field emission scanning electron microscope (SEM) and energy dispersive spectrometer (EDS), and the oxidation mechanism at high temperature was analyzed. The results show that the oxide film can be divided into two layers after oxidation at 650 ºC for 200 h. The outer oxide film is mainly composed of Fe and Cu oxides, and the inner oxide film is mainly composed of Al2O3, SiO2 and Cr2O3. After oxidation at 700 ºC for 200 h, the outer layer is mainly composed of Fe, Cu, Mn oxides, and the inner layer is mainly composed of Cr, Al and Si oxides. The addition of a small amount of Cu promotes the diffusion of Al and Si elements, facilitates the formation of Al2O3 and SiO2, and improves the high-temperature oxidation resistance of martensitic heat-resistant steel.
