El amanecer de la nación. Un aporte sobre el libro nudos y voces en la república de Boris Espezua
Authors: Diaz Montenegro Walter
Published: January 2023

El presente trabajo efectúa un examen descriptivo del tema de la cuestión nacional que aborda el libro de Espezúa. Se ha puesto énfasis en una contextualización de tipo histórico-cultural que, necesariamente, exige la cuestión de la identidad ante una perspectiva nacional que hoy sabemos se extiende al Incario, la Colonia, la República y el Perú Contemporáneo. Igualmente, se ha profundizado en las obras de Garcilaso de la Vega y Ga-maliel Churata debido a su implicancia en el ámbito de la Cosmovisión Andina. Muy diferente ha sido el enfoque realizado acerca de Basadre y cuyo aporte, consideramos, puede haber sido el origen del libro del autor. Finalmente, se ha profundizado en la última sección del libro, debido que es allí donde el tema de la actual crisis nacional ha sido reelaborado en la forma de una afirmación, pero que a la vez muestra el enorme impacto que ha causado la crisis actual en la sensibilidad artística del autor.
Upravljačko računovodstvo okoliša u kontekstu društveno odgovornog poslovanja
Authors: Hladika Mirjana
Published: January 2023

Interes za društvenu odgovornost, održivost i njezine implikacije na poslovanje kontinuirano se povećavao otkako je ovo pitanje postalo aktualno prije nekoliko desetljeća. Sve se više priznaje da održivost ne postavlja samo etička pitanja nego ima i izravne implikacije na gospodarski učinak. Razvoj regulatornog okvira, tehničke i organizacijske inovacije te nove percepcije društva i potrošača promijenili su poslovni kontekst i determinante korporativnog uspjeha. Sve je to imalo implikacije na računovodstvenu profesiju koja podupire poslovanje, a upravljanje održivošću stvorilo je zahtjeve za novim informacijama i prilagodbama tradicionalnog računovodstva kako bi podržalo proširene informacijske zahtjeve korisnika. U tom kontekstu, upravljačko računovodstvo okoliša doživjelo je značajnu popularnost tijekom posljednjih nekoliko desetljeća te se promovira kao sredstvo pomoću kojeg organizacije mogu lakše upravljati svojim ekološkim i s njime povezanim ekonomskim učinkom čime doprinose društvenoj odgovornosti. Za održavanje održivog globalnog gospodarskog rasta, svaka organizacija mora biti aktivno uključena u procese zaštite okoliša kao što su smanjenje troškova energije i resursa, inoviranje poslovnih procesa i proizvoda, poboljšanje učinkovitosti proizvodnje te smanjenje troškova usklađenosti. U ovome radu predstavljena je analiza objavljenih teorijskih i empirijskih istraživanja s ciljem utvrđivanja uloge koju upravljačko računovodstvo okoliša ima u postizanju društveno odgovornog poslovanja te generiranju informacija koje ukazuju na ekološku učinkovitost i njihovo objavljivanje u izvještaju o društvenoj odgovornosti. Rezultati istraživanja pokazali su da upravljačko računovodstvo okoliša omogućava lakšu integraciju pitanja okoliša u donošenje upravljačkih odluka pružanjem nefinancijskih i financijskih informacija o utjecaju organizacije na okoliš.
Politička propaganda i lažne vijesti
Authors: Topić Crnoja Matea , Palić Mirko
Published: January 2023

Glavna tema ovog rada je analizirati koncept političke propagande i njene tranzicije s tradicionalnih medija na društvene mreže te posljedica do kojih pritom dolazi u javnom prostoru kroz razvoj cijele nove paradigme informacijskih balona u kojima su korisnici okruženi samo istomišljenicima te informacijama i vijestima koje podupiru njihov svjetonazor i sustav vrijednosti. Cijeli ovaj sustav često je omeđen lažnim vijestima koje je teško razlikovati od onih istinitih. Istraživanja, ali i primjeri navedeni u radu pokazuju da postoje brojni primjeri uspješne političke propagande temeljene na lažnim vijestima i njihovom viralnom prenošenju putem društvenih mreža. U radu se propitkuju suvremena rješenja i napori različitih društvenih mreža, ali i nacionalnih zakonodavstava u označavanju i ograničavanju širenja dezinformacija. Za sada se čini da rješenje ne leži samo u naprednim algoritmima i velikom broju zaposlenih „fact checkera“ već i u sustavnoj edukaciji i osvješćivanju korisnika da aktivno traže različite poglede i rješenja za pitanja koja ih zanimaju kako bi proširili i u konačnici razbili svoj informacijski „mjehurić“.
Shell structures: lessons in structural efficiency for sustainable construction
Authors: Nanayakkara Kavinda Isuru
Published: January 2023

Shells are a highly efficient, lightweight structural form that have been used in construction for thousands of years. Shell structures can be formed from a wide range of materials – from compressed earth to concrete – allowing local materials to be used in their construction. However, social and economic factors mean that local materials are often perceived as inferior to steel or concrete in developing countries. In this article, stemming from his Pai Lin Li Travel Award in 2018, Isuru Nanayakkara looks at traditional technologies and modern approaches to lightweight shell construction to seek a better perspective on how shell technology can be appropriated to different local contexts.

Obesity is a chronic, multifactorial condition described as an abnormal or excessive buildup of body fat that endangers an individual's health. It is a huge global public health problem. Prednisone and anti-psychotic medicines are known to cause weight gain and  obesity. In this era of precision medicine, it is critical to identify individuals who are most likely to gain weight as a result of pharmaceutical use. Hypoglycemic anti-diabetes medicines, psychotropic agents (atypical antipsychotics, antidepressants), anticonvulsant and mood stabilizer agents, and different hormones are the most regularly reported prescription groups that may cause weight gain. The obesity pandemic is multifaceted, but medication-induced weight gain may play a role. While doctors may aim to pick pharmacotherapies  with the least detrimental influence on weight, the literature on the weight effects of medicine is frequently inadequate and empty of alternative treatments. Because of the devastating consequences of adolescents  obesity, new therapies are desperately needed. Real-world data reveal that the majority of teenagers do not lose weight over time, and pharmacological therapy should be recommended.

relación causal entre la mente y el cuerpo
Authors: Guarino Juan Ignacio
Published: January 2023

El problema de la relación causal entre el cuerpo y la mente parece merecer, por su importancia y el tiempo a él dedicado, un capítulo aparte en la teoría del conocimiento, en la filosofía de la mente y en las ciencias cognitivas. El dualismo cuerpo-mente dificulta enormemente la explicación teórica de un nexo causal entre uno y otro, problema central en la filosofía de Descartes, más fácilmente rastreable en autores anteriores como san Agustín o Platón. En el presente trabajo analizaremos el desarrollo efectuado por John Searle con el fin de superar este problema mediante una reformulación teórica de los conceptos involucrados en su descripción y conceptuación. Su tratamiento se basa en el reemplazo del concepto tradicional de causalidad por uno más complejo, mediante la introducción teórica de diferentes niveles de observación y del concepto de realización, integrante de este nuevo concepto de causalidad.

Published: January 2023

Milk and its products play important role in enhancing food security among communities who keep livestock and leave in the rural areas of Kenya. Traditionally fermented milk is one of the milk products, which contain live microorganisms (Probiotic) which when consumed in adequate amounts confer health benefits to the host. However, the extent to which children access the health benefits is not known because of limited information on household production and consumption frequency of these milk products in the regions. Available knowledge on production and consumption frequency of traditionally fermented milk products can provide valuable information for targeting specific measures for developing and promoting them as transition foods for young children. The objective of this study therefore, was to establish household production and consumption frequency of one such milk product Mursik, by 1-5 years old children in Uasin Gishu County, Kenya. A cross-sectional study involving 382 Kalenjin households (HHs) was conducted within Kapseret location in August 2013. Structured questionnaires and a focused group discussion (FGD) question guide were the main instruments of data collection. The study employed both quantitative and qualitative methods of data collection. A two-stage sampling method was used to select the villages and households in which questionnaires were administered and data was analyzed using the Statistical Packages for Social Sciences (SPSS) version 16.0 for windows and tested for significance at P < 0.05. Results showed that households with daily production of ≤ 5 litres of fresh milk prepared the greatest share (60%) of mursik. There were significant differences (p< 0.05) between mursik production and the levels of HH fresh milk production, age group (P= 0.035) of respondents in households and mursik production levels (χ2 = 0.1332, p =0.0041) and consumption frequency among children. Households producing > 5 litres of mursik fed their children more frequently (75%) at more than once per day. Although mursik formed an integral part of household food in Kapseret Location only 28% (n=108) of households fed children with it. Therefore, mursik consumption among children should be promoted to improve their health status.
Distribution, abundance and habitat selection of Eriogaster catax (Linnaeus, 1758) in Álava (Spain) (Lepidoptera: Lasiocampidae)
Authors: De Juana F. , Aedo O.
Published: January 2023

The presence of Eriogaster catax has been confirmed in 49 locations in the province of Álava and in three locations within the Condado de Treviño in the province of Burgos, corresponding to 27 UTM squares of 10 x 10 km. This brings the total number of known squares for Spain to 72, which represent a 53% increase with respect to the previous knowledge in this country. This species is widely distributed in the study area, occupying both the supratemperate and supramediterranean ecosystem layers. Nevertheless, density levels appear to be very low. With regard to habitat, this species exhibits a clear preference for gall-oak groves and their degradation stages, located mainly on the lower sections of mountain slopes and always on basic substrates. In every case, the species chosen for egg-laying were Crataegus monogyna or Prunus spinosa, in similar proportions.

Políticas Aproximadas e Parciais Sensíveis a Risco para o Controle da Propagação de Doenças Infecciosas
Authors: Pastor Henrique Dias , Delgado Karina Valdivia , Freire Valdinei , Barros Leliane Nunes de
Published: January 2023

Os Processos de Decisão de Markov (MDPs) podem ser usados para controlar a propagação de doenças infecciosas e encontrar uma política ótima de controle de vacinação. No entanto, por se tratar de um problema que envolve vidas, é necessário levar em consideração a atitude do agente em relação ao risco. Assim, neste trabalho, são usados MDPs sensíveis ao risco com o modelo compartimental SIR e são propostos dois algoritmos eficientes para encontrar políticas de vacinação otimizadas que permitam controlar a propagação de uma doença infecciosa, ou seja, selecionar o número de indivíduos que devem ser vacinados a cada período considerando um parâmetro que representa a atitude frente ao risco. A primeira solução proposta encontra uma política de vacinação que é parcial e ótima dada uma determinada atitude de risco. A segunda solução proposta é aproximada e assim pode resolver problemas ainda maiores. Os resultados mostram que: (i) as políticas de vacinação dependem não apenas da taxa básica de reprodução R0, como esperado, mas também do custo e da atitude em relação ao risco de um agente; e (ii) ambas as soluções obtêm um grande ganho de tempo de execução e pouca perda de qualidade quando comparadas com as políticas completas e não aproximadas.

Hoje vivemos uma mudança de paradigma no setor financeiro, com forte redução das agências bancárias físicas e aumento de serviços online. Contudo, a facilidade de abertura de contas digitais propiciada por esta mudança de paradigma também tem levado a um aumento nos casos de fraude. Este trabalho apresenta o problema de detecção de fraude financeira sob uma nova taxonomia e, também, investiga técnicas de classificação hierárquica para a tarefa. A abordagem hierárquica global (CLUS-HMC), em que toda a hierarquia de classes é considerada pelo classificador, resultou em melhores valores de Recall para as classes fraudulentas (33.31% para classe E e 35.09% para classe F), indicando um caminho de pesquisa promissor.

Com os avanços das técnicas de processamento e análise de imagens, o uso de sistemas de reconhecimento biométrico em tarefas cotidianas das pessoas já é uma realidade. Dentre essas tarefas estão desde um simples acesso aos dispositivos móveis até a marcação de amigos em fotos compartilhadas em redes sociais e as complexas operações financeiras em equipamentos de autoatendimento para transações bancárias. Em 5 de julho de 2021, o governo brasileiro anunciou a compra de um sistema de reconhecimento biométrico para ser utilizado em todo território nacional. Neste sentido, este artigo propõe a abertura de uma discussão mais aprofundada sobre a adoção de tais sistemas para a identificação dos cidadãos brasileiros e quais os problemas que podem emergir se o sistema não for bem projetado, implantado e gerenciado. Além disso, uma lista de dez questões foi criada para iniciar essa conversa sobre segurança dos dados dos brasileiros na Era da Inteligência Artificial (IA) e o respeito à Lei Geral de Proteção dos Dados (LGPD).

Published: January 2023

A distribuição de candidatos em locais de provas é um problema logístico relevante e afeta diversos países, inclusive o Brasil, que realizam exames de seleção por meio de avaliações presenciais. Definir uma distribuição adequada considerando critérios como distância, custo e ocupação é uma tarefa desafiadora. Este trabalho trata a tarefa em questão como um problema combinatório de casamento estável e propõe um novo algoritmo de otimização (O2MSM) para a distribuição automática de candidatos a locais de teste. O O2MSM visa encontrar uma correspondência estável entre candidatos e locais de prova, minimizando a distância entre eles e o número de locais de prova e maximizando a taxa de ocupação desses locais. Os resultados mostraram que o O2MSM superou a abordagem baseline, sendo mais eficiente, realizando a distribuição dos candidatos em segundos, e mais eficaz, reduzindo ao máximo o número de locais de prova, vagas e distância dos candidatos.
Tractable Mode-Finding in Sum-Product Networks with Gaussian Leaves
Authors: Madeira Tiago , Mauá Denis Deratani
Published: January 2023

In this work, we leverage the relation between Sum-Product Networks (SPNs) and Gaussian mixtures to propose an algorithm that adapts the Expectation-Maximization method to efficiently find the modes of SPNs with Gaussian leaves. We discuss how the algorithm can be used to perform Maximum-A-Posteriori inference in SPNs learned from continuous data with theoretical advantages over the existing methods in the literature, and how it can be used to shrink the size of learned models. As an additional example of the use of the algorithm, we perform an SPN-based hierarchical clustering of digit images. Thus, our proposed algorithm can be used for model analysis, model compression, and exploratory data analysis.

Pulmonary Embolism is an affection caused by obstruction of the pulmonary artery or one of its branches. This condition imposes a high mortality incidence, in the United States approximately 100.000 deaths per year. Computed Tomography Pulmonary Angiography is a radiologic modality and an essential technology for diagnosing this disease, providing a series of axial images. We trained two Convolutional Neural Networks (Efficient Net B0 and Resnet 3D 18) in the RSNA-STR Computed Tomography Pulmonary Angiography Dataset to identify this affection. After training these Convolutional Neural Networks, we added a new layer to the architecture by exploring the dependency between the images along the exam using Long Short-Term Memory or Temporal Convolutional Networks. With the models trained and tested, we compared these different approaches using different metrics. As a result, the Temporal Convolutional Network approach with Resnet 3D 18 improved significantly compared to the results found in the other methods. The main contribution of this work was to observe how different combinations of architectures can help classify Computed Tomography Pulmonary Angiography.

Um desafio na modalidade EaD é combater a evasão, que segundo a ABED, varia entre 21 e 50%. Para este fim, diversos métodos de mineração de dados foram aplicados, utilizando dados de interações dos alunos no AVA. Contudo, um problema relevante é selecionar as melhores características (variáveis/atributos) para predição da evasão. Neste artigo, propomos um arcabouço que utiliza métodos de explicabilidade (XAI-SHAP) para selecionar atributos com maior poder preditivo em VLE que utilizam CMS terceirizados. Após a seleção, o modelo proposto alcançou resultados de recall 0,96 e precision 0,95, compatíveis com o estado da arte, porém utilizando um conjunto menor de atributos e uma base de dados com menor número de instâncias.
An agent-based approach to procedural city generation incorporating Land Use and Transport Interaction models
Authors: Santos Luiz F. S. Eugênio dos , Aranha Claus , Carvalho André P. de L. F. de
Published: January 2023

We apply the knowledge of urban settings established with the study of Land Use and Transport Interaction (LUTI) models to develop reward functions for an agent-based system capable of planning realistic artificial cities. The system aims to replicate in the micro scale the main components of real settlements, such as zoning and accessibility in a road network. Moreover, we propose a novel representation for the agent’s environment that efficiently combines the road graph with a discrete model for the land. Our system starts from an empty map consisting only of the road network graph, and the agent incrementally expands it by building new sites while distinguishing land uses between residential, commercial, industrial, and recreational.

The German National Academics Panel Study (Nacaps). A New Longitudinal Survey on Early Researchers’ Careers and Life Courses
Authors: Briedis Kolja , Hoffstätter Ute , Schwabe Ulrike
Published: January 2023

Against the backdrop of educational expansion and knowledge economies, doctorate holders are seen as a core potential for economic growth and innovation in general. However, there is a considerable need for adequate data to gain empirical knowledge on the individual and structural determinants as well as the (long-term) career effects of obtaining a doctoral degree. Therefore, the German Centre for Higher Education Research and Science Studies (DZHW) has recently implemented a new multi-cohort panel survey, the “German National Academics Panel Study” (Nacaps); its aim is to improve the German database on doctoral candidates and doctorate holders. As of July 2020, the first wave of Nacaps cohort 2018 is available via the Research Data Centre for Higher Education Research and Science Studies (FDZ-DZHW) for scientific research and teaching purposes. This contribution introduces the overall study design with a comprehensive description of sampling strategy, access to respondents and response rates as well as the topics covered in the study and the theoretical constructs. Furthermore, we explain data access and anonymisation measures, enabling users to comprehend the data packages available for secondary analysis. We then illustrate the analytical potential using (international) mobility and health as examples. We close with some general remarks on the strengths and limitations of the Nacaps data and provide a forecast for upcoming waves and cohorts.
„Bernzieh“ und Esperanto. Technische Terminologie im Nationalsozialismus zwischen Sprachpurismus und internationaler Normung
Authors: Gabriel Peter
Published: January 2023

Anfang der 1930er Jahre festigten sich bei den technisch-wissenschaftlichen Vereinen in Deutschland die Regeln zur Festlegung ihrer Terminologie im Rahmen der internationalen Normung. Mit dem Machtantritt der National- sozialisten gelang es Sprachpuristen, ihren Verdeutschungsaktivismus in der Gemeinschaftsarbeit der Vereine zu platzieren. 1937 aber verbot Fritz Todt, der führende NS-Technikfunktionär, die sprachpuristischen Arbeiten, während die Vereine die auf internationaler Kooperation und der Plansprache Esperanto aufsetzende Institutionalisierung der technischen Terminologie fortführten. Der Beitrag untersucht an diesem Beispiel die gesellschaftspolitische Stellung der Ingenieure im Dritten Reich, die weniger von einem Widerspruch zwischen technischer Rationalität und NS-Ideologie oder einer „Politisierung der Technik“ (Meyer) geprägt war als von der Integration der technisch-wissenschaftlichen Vereine in die „neue Staatlichkeit“ (Hachtmann) des Regimes.
Europäische Souveränität als mehrdimensionaler Rechtsbegriff
Authors: Lührs Lisa-Marie
Published: January 2023

Der Diskurs über Europäische Souveränität ist in der politischen Praxis und Wissenschaft bereits fortgeschritten. Ziel des Beitrags ist es, die Tragfähigkeit des sich zunehmend etablierenden Begriffs für die Rechtswissenschaft auszuloten und ein Angebot zu unterbreiten, wie Europäische Souveränität rechtswissenschaftlich zu deuten ist. Dazu konstruiert der Beitrag Europäische Souveränität als rechtlichen Begriff und beleuchtet diesen anhand verschiedener Souveränitätsdimensionen. Demnach ist Europäische Souveränität im rechtlichen Sinne als beschränkte Souveränität zu verstehen, die gemeinsam durch die EU und ihre Mitgliedstaaten wahrgenommen wird. Dieses Souveränitätsverständnis verteilt Souveränität graduell nach Verantwortungsbeiträgen zwischen der EU und den EU-Mitgliedstaaten und lässt sich zudem auf die klassischen Dimensionen innere und äußere Souveränität übertragen.
Abgeordnete ohne Grenzen? Das Europäische Parlament und die Entstehung des Schengener Abkommens
Authors: SCIANNA Bastian Matteo
Published: January 2023

This article investigates the long-neglected influence of the European Parliament (EP) in the field of free movement of persons and the abolishment of border controls in the European Community (EC). Since the immediate post-war period, parliamentarians lobbied for a new mobility regime in Europe. In the early years, this was mainly done in the Council of Europe’s (then) Consultative Assembly, before the EC’s fora became more important. By trying to abolish visas, border formalities and controls, the parliamentarians spearheaded initiatives that some member states were also pursuing. The Council’s decision in 1975 to introduce a common format passport was a decisive step and after the direct elections to the EP in 1979, the activism in this field gained traction. Particularly a trio of German members (Karl von Wogau, Dieter Rogalla and Horst Seefeld) and the so-called Kangaroo Group developed effective strategies to spread their ideas and influence policy by including regional, national and supra-national actors as well as their parties and groups in the EP. The years 1981-1984 brought essential changes and lead to the Schengen Agreement in 1985, in which the EP’s role has long been neglected.
Fluchtforschung als Demokratieforschung: Ein Dialog zwischen politischer Philosophie und empirischen Sozialwissenschaften

Studien, die Fluchtanalysen explizit als Demokratieforschung denken, sind relativ jung. Ebenso steht die Debatte um eine Demokratisierung der Fluchtforschung selbst erst am Anfang. Der folgende Beitrag bringt eine Auswahl an Ansätzen aus Politischer Philosophie und empirischer Sozialwissenschaft miteinander ins Gespräch, die zur Bearbeitung dieser Problemstellung beitragen können. Im Zentrum der Auseinandersetzungen stehen Fragen nach der politischen Exklusion Geflüchteter, nach den Formen ihrer politischen Partizipation sowie nach den (Un-)Möglichkeiten, die wissenschaftliche Beschäftigung mit dem Thema Flucht selbst partizipativer und damit demokratischer zu gestalten. Wir argumentieren, dass das Wechselverhältnis von Demokratie und Flucht nur im Dialog verschiedener Disziplinen und methodischer Herangehensweisen angemessen bearbeitet werden kann.
Street Art und Urheberrecht
Authors: Zott Christian
Published: January 2023

Street Art erfreut sich seit geraumer Zeit zunehmender Beliebtheit und wird daher auf dem Kunstmarkt ebenfalls verstärkt nachgefragt. Spätestens seitdem die Werke Banksys immer neue Verkaufsrekorde erzielen, ist diese Kunstform ins Zentrum auch des kommerziellen Interesses gerückt. Dies belegen neben zahlreichen Fotobüchern, die sich mit dem Thema befassen, außerdem verschiedene touristische Angebot zu Street Art, wie etwa geführte Touren zu den beliebtesten Werken der Stadt, oder diverse Merchandising-Artikel, die mit den Stencils bekannter Künstler verziert sind.

Diese Verwertung findet in der Regel allerdings ohne die Zustimmung der Künstler statt, die sich oft nicht aus der Anonymität herauswagen, um einer möglichen Strafverfolgung wegen der meist rechtswidrigen Installation ihrer Kunstwerke zu entgehen. Hieraus ergeben sich verschiedene urheberrechtliche Fragestellungen, die bisher lediglich punktuell bearbeitet worden sind.

Der Autor beleuchtet die Frage, inwiefern es den Urhebern der Street Art möglich ist, die kommerzielle Nutzung ihrer Werke unter Berufung auf ihr Urheberrecht zu untersagen.
Datenschutzrechtliche Pflichten zur Einrichtung eines unternehmensinternen Datenschutz-Managementsystems
Authors: Janicki Thomas
Published: January 2023

Die Einhaltung des Datenschutzrechts wird für Verantwortliche zu einer stetig herausfordernderen Aufgabe. Datenschutz-Managementsysteme knüpfen hieran an und helfen dabei, die Datenschutz-Compliance in der Organisationseinheit effektiv und möglichst effizient zu gewährleisten. Ihre Einrichtung bleibt allerdings ein umfangreiches und kostspieliges Projekt. Insbesondere klein- und mittelständische Unternehmen, ebenso aber selbständige Personen, werden im Vergleich zu Großunternehmen und Konzernen mit solch einer Einrichtung strukturell und finanziell überfordert. Fraglich bleibt insgesamt, ob solche komplexen Systeme auch gesetzlich verpflichtend eingerichtet werden müssen. Das vorliegende Werk geht dieser Frage nach und liefert eine Antwort, ob Pflichten zur Einrichtung des Datenschutz-Managementsystem bestehen.

Ultrasound-Guided Stellate Ganglion Radiofrequency in a Patient with Ventricular Tachycardia Sensitive to Implantable Cardioverter Defibrillator: A Case Report
Authors: Rahimzadeh Poupak , Saif Amir-Aziz
Published: January 2023

Introduction: Electrical storms and ventricular tachycardia are two life-threatening arrhythmias that are becoming more common. In developing ventricular arrhythmias, the sympathetic nervous system plays a vital role. Stellate ganglion (SG) block can be used in many situations as an important therapeutic target, like treating tachyarryhthmias and ventricular tachyarrhythmias. Case Presentation: The patient was a 53 years old woman with a history of implantable cardioverter defibrillator (ICD) insertion due to ventricular tachycardia. The patient complained of an awkward and unpleasant sensation when the ICD sensed the tachyarrhythmia and shocked her. Regarding the positive response to the previous SG block, with the goal of a longer duration of this effect, stellate ganglion radiofrequency was performed. Conclusions: Stellate ganglion radiofrequency shows a safe and long-term effect for patients with tachyarrhythmias and ICD who cannot tolerate episodes of ICD activation.

Published: January 2023

Introduction: Laryngospasm is a life-threatening condition caused due to involuntary contraction in laryngeal muscles. It can last seconds to minutes and may cause hypoxemia, loss of consciousness, and death. Case Presentation: We report a case of laryngospasm in a patient with Coronavirus-2 infection who was admitted to the emergency department for the first time. Laryngospasm was revealed after treatment. Conclusions: The clinician should note that laryngospasm can be triggered by Coronavirus-2 infection.

Published: January 2023

Background: Mitral valve stenosis (MS), which could be progressive, is one of the most important valvular disorders in developing countries. Percutaneous transvenous mitral commissurotomy (PTMC) is a well-accepted treatment option for dealing with symptomatic MS. Brain natriuretic peptide (BNP) has been used as a prognostic marker for clinical outcomes in patients with heart failure and acute coronary syndrome routinely. Objectives: This study aimed to determine the relationship between BNP levels and hemodynamic parameters in patients with MS who underwent PTMC. Methods: In this case-control study, 90 patients with severe isolated rheumatic mitral stenosis and undergoing PTMC were enrolled. In the study group, BNP levels were measured by performing radioimmunoassay on all participants 30 minutes before PTMC and 24 hours after PTMC. Data were analyzed using SPSS, and P-value < 0.05 was considered significant. Results: Fifty patients with MS who underwent PTMC were included in this study. The level of BNP before PTMC was 473.78 ± 66.95 pg/dL in patients with MS. The level of BNP in patients after PTMC reached 341.54 ± 48.3 pg/dL, which was indicative of a significant reduction in the level of BNP after PTMC (P-value = 0.006). Conclusions: A considerable decline was observed in the serum level of BNP following a successful PTMC, which was indicative of an improvement in clinical and hemodynamic status; hence, it was reasonably suggested that the serum level of BNP was effective in evaluating the response from patient with severe MS to PTMC.
A Case-report of Concurrent Pulmonary and Cerebral Lesions in a Patient with Polymyositis: Invasive Aspergillosis or Astrocytoma?
Authors: Tehrani Shabnam , Yadegarynia Davood , Keyvanfar Amirreza
Published: January 2023

Introduction: Polymyositis is an idiopathic inflammatory myopathy that mainly manifests itself with muscle weakness. Patients with polymyositis have a higher risk of developing infections and malignancies. We report concurrent pulmonary and cerebral lesions in a polymyositis patient with many diagnostic challenges. Case Presentation: A 56-year-old woman complained of a productive cough and dyspnea from two weeks ago. Her symptoms gradually progressed until a sudden loss of consciousness occurred. She was a known case of polymyositis and was treated with oral prednisolone. Imaging revealed concurrent pulmonary and cerebral lesions. Initially, the patient underwent empirical therapy. However, the patient underwent a bronchoscopy because she did not respond to treatment. Specimens obtained from respiratory secretions revealed branched septate hyphae, and the culture was positive for Aspergillus fumigatus. She was diagnosed with invasive aspergillosis, so we replaced the therapy with voriconazole. After three months, the lung lesions improved, but the number and extent of cerebral lesions increased. Finally, after a stereotactic biopsy, the patient was diagnosed with astrocytoma and became a candidate for radiotherapy. Conclusions: Patients with polymyositis are prone to contracting opportunistic infections and malignancies. Both of them can mimic each other and present diagnostic challenges to physicians. Thus, they should think about them for early diagnosis and timely treatment.
Rekonštrukcia spisovej a zväzkovej agendy tajného spolupracovníka s krycím menom „BUREŠ.“ Andrej Babiš ako spolupracovník Štátnej bezpečnosti v rokoch 1980 – 1989

The paper describes the efforts made by a top Czech politician to exonerate himself and details the archival research conducted by Ústav pamäti národa [the Institute of the Nation’s Memory] that led to findings refuting his claims in court. Although the State Security Service (ŠtB) managed to shred a number of files in December 1989, it did not manage to destroy all evidence. Although incomplete, the information can be verified by reconstructing the records and piecing together a mosaic of relationships. Based on the assessment of these records and files in the context of the overall activities of the State Security Service and the relevant guidelines for the activities of counterintelligence officers, for working with counterintelligence collaborators and for record keeping, statistics and administration of counterintelligence activities, it can be concluded that the file of the confidant and, later, agent code-named “BUREŠ” was – despite minor administrative shortcomings – created, kept on record and maintained by the relevant units of the ŠtB in accordance with the internal regulations of the Ministry of the Interior of the Czechoslovak Socialist Republic.

Postpartum reproductive performance closely depends on uterine health. Under normal circumstances, almost 100% of cows haveuterine contamination within first 2 weeks after calving. Whereas the innate immune and reproductive systems usually eliminatemost offending microbes, persistent infection still reportedly occurs in ~ 20% of postpartum cows. Our purpose was to estimateconcentrations of systemic immune indicators (IgG, white blood cells, and fibrinogen) during the transition period in dairy cowswith and without endometritis. Fifty-nine multiparous cows were systematically and consecutively enrolled during the dry periodand examined 6 times from 40 days before to 40 days after calving. Cows in the diseased group (n = 11) were identified based on4 criteria (presence of Trueperella pyogenes grade > 2 in the uterus, clinical endometritis, subclinical endometritis, and cervicitis).Cows in the control group (n = 11) were negative for all 4 criteria. Prevalence of Trueperella pyogenes, clinical endometritis, subclinicalendometritis, and cervicitis was 25, 16, 23, and 31%, respectively. Concentrations of IgG, white blood cells, and fibrinogen didnot change over the period or vary among control and diseased cows. In conclusion, systemic indicators of inflammation were notgood markers for diagnosing or monitoring endometritis in postpartum dairy cows.
