É o capital um acelerador?
Authors: Fortes Silveira Felipe , Dos Santos Pirola Émerson 
Published: July 2024

O capitalismo moderno não raro é definido por sua velocidade e aceleração em comparação a formações sociais anteriores. Contemporaneamente, ganhou certa relevância a posição teórica conhecida de maneira genérica como “aceleracionismo”, que coloca, em linhas gerais, que o capital é uma força motriz de desenvolvimento, progressão e, consequentemente, aceleração, incitando revoluções e rupturas nos modos de organização social, e, dessa maneira, não sendo um processo de desterritorialização que possa ser contido, a aceleração do capital é vista como um imperativo. Imanentemente Ã essa corrente, surgem, Ã esquerda, uma contraposição Ã ideia de que é o capital que deva ser acelerado, alertando ao bloqueio e restrição que o capital provoca nas forças produtivas sociais, abrindo espaço para uma reapropriação sócio-técnica e uma aceleração contrária ao desenvolvimento do capital, em direção Ã um pós-capitalismo. Em nossa perspectiva, por mais que essas vertentes tenham contribuições importantes ao debate sobre o desenvolvimento do capitalismo, elas perdem de vista a centralidade das forças produtivas e da produção desejante como o real vetor da aceleração. Voltando sobretudo a Deleuze e Guattari e Ã matriz teórica do (pós-)operaísmo, buscamos ao analisar, tanto o aceleracionismo de Nick Land quanto o aceleracionismo de Alex Williams e Nick Srnicek, tomadas por nós como os principais vetores de duas tendências aceleracionistas, os pontos frágeis em seu desenvolvimento teórico, buscando afirmar a tese de que, são as forças produtivas desejantes que aceleram a produção ativa de suas linhas de fuga em um processo de antagonismo, ao qual o capital e seus aparelhos de captura devem, “correndo atrás” em um segundo momento estrutural, capturar por um movimento aceleratório e progressivo.
Sonoridade de Eros nas canções do Blues Clássico de Bessie Smith
Authors: Nascimento Barroso Nathalia 
Published: July 2024

O objetivo deste artigo é apresentar como o Blues Clássico de Bessie Smith exemplifica a possibilidade de mudanças ocorrerem através da dimensão estética. Como referências utilizaremos as obras Eros e Civilização: Uma interpretação filosófica do pensamento de Freud, An Essay on Liberation e The Aesthetic Dimension: Toward a Critique of Marxist Aesthetics, de Herbert Marcuse, a fim de demonstrar como a música apresenta um poder persuasivo sobre as mentes e corpos dos ouvintes. Utilizaremos também a obra Blues Legacies and Black Feminism: Gertrude “Ma” Rainey, Bessie Smith and Billie Holiday, de Angela Davis, na qual o Blues é apresentado enquanto o meio para a expressão e transmissão das ideias e pensamentos das mulheres negras capaz de provocar mudanças na consciência negra norte-americana. Bessie Smith foi uma das mais conhecidas cantoras do Blues Clássico e recebe destaque neste artigo. A cantora preservou em suas canções uma herança africana a ser apresentada aos negros norte-americanos que servia de incentivo à modelos alternativos de comportamento e atitudes em relação aos estabelecidos.

Risk Management Plan: Expert Review of Applications for Marketing Authorisation in the EAEU Depending on the Type of Medicinal Product (Review)
Authors: Bukatina T. M. , Shubnikova E. V. 
Published: July 2024

INTRODUCTION. A risk management plan (RMP) is an important document for assessing and managing risks when using a medicinal product. An RMP is provided as part of the marketing authorisation application for a medicinal product. The requirements for the need to submit an RMP and the information in its sections depend on the type of medicinal product and marketing authorisation procedure. Marketing authorisation holders will benefit from an expert systematisation of the requirements for RMP submission outlined in the Eurasian Economic Union (EAEU) Rules for Marketing Authorisation and Expert Assessment of Medicinal Products for Human Use and Rules of Good Pharmacovigilance Practice (Eurasian Economic Commission Council Decisions Nos. 78 and 87 dated 03.11.2016, respectively), as this systematisation will contribute to a more accurate drafting of RMPs.AIM. This study aimed to analyse the requirements for submitting parts and modules of an RMP depending on the type of medicinal product being authorised according to the EAEU marketing authorisation procedures.RESULTS. This review analyses and systematises the requirements for the development of an RMP and the submission/non-submission of its main parts (I–VI) and Part II modules (CI–CVIII) depending on the type of medicinal product and marketing authorisation procedure. The article describes the principles for providing information in three main RMP sections: Safety Specifications (Part II), Pharmacovigilance Plan (Part III), and Risk Minimisation Measures (Part V). Flow charts illustrate summarised information on pharmacovigilance activities and risk minimisation measures that is included in an RMP. The article systematises the considerations for the analysis and evaluation of information for the main parts (I–VI) and Part II modules (CI–CVIII) of an RMP.CONCLUSIONS. The systematisation of the requirements of Eurasian Economic Commission Council Decisions Nos. 78 and 87 dated 03.11.2016, as well as the expert comments on considerations for RMP submission depending on the type of medicinal product and marketing authorisation procedure will help to improve the quality of RMPs and, in general, the safety of medicinal products authorised in the EAEU.
Myocardial bridge of the left anterior descending coronary artery as a cause of acute coronary syndrome and ventricular tachycardia in a young patient. Case report
Authors: Rudenko I. V. , Bezrodnyi A. B. , Mostbauer H. V. 
Published: July 2024

Myocardial bridges (MM) are common congenital anomaly of the coronary arteries (CA) with the location of a separate bundle of myocardial muscle fibers over any epicardial vessel, most often over the middle segment of the left anterior descending coronary artery (LAD). In most patients, MM has a benign course, though in 25% of cases, it can cause stable or unstable angina, myocardial infarction with non‑obstructive CA (MINOCA), paroxysmal rhythm disturbances, and sudden cardiac death. The pathophysiological mechanisms of the development of fatal and non‑fatal cardiovascular events in such patients are heterogeneous and usually complex. They may include mechanical obstruction of blood flow, violation of diastolic relaxation of the CA, local hemodynamic changes in the tunnelled segment, endothelial dysfunction, vasospasm, damage to the atherosclerotic plaque located in the MM zone, and spontaneous dissection of the CA.
The purpose of our article was to present and discuss a clinical case of the development of MINOCA and potentially fatal ventricular arrhythmia in a 34‑year‑old man during competitive sports caused by MM in the LAD. MM was detected by invasive angiography. The diagnosis of MINOCA was established according to the criteria of the 4th universal definition of MI (clinical signs, ECG data, laboratory markers of myocardial damage). However, according to magnetic resonance imaging (MRI) of the heart 3 days after the onset of the disease, no inflammatory process, ischemic damage to the myocardium, and volume formations were found. At the same time, dilatation and hypertrophy of the left ventricle and myocardium fibrosis of non‑ischemic origin were present.
There is currently no generally accepted algorithm for examining a patient with MM. Because of the heterogeneity of the pathophysiological mechanisms of myocardial ischemia in this cohort of patients, it is suggested to use invasive and non‑invasive angiography, invasive methods of intracoronary imaging, Doppler assessment of coronary blood flow, and provocative stress tests to detect vasospasm.
Modern approaches to the choice of safe therapy of gallstone disease
Authors: Fadieienko G. D. , Kushnir I. E. 
Published: July 2024

Gallstone disease (GD) is one of the most common digestive disorders. Its prevalence among the adult population of the developed countries of Europe and North America accounts near 20% and increases annually. The significance of this pathology is stipulated by not only medical, but also social aspects due to it often defeating persons of the most working age with the high rates of temporary and permanent incapacity due to the involvement of adjacent organs in the pathological process — liver, pancreas, stomach with further progression and development of complications. The article highlights physiological mechanisms of bile formation, as well as the main reasons for the gallstone’s formation in the gallbladder. Presented the data from the recent scientific research on the role of genetic factors and gastrointestinal microbiome, as well as functional disorders of the gallbladder, sphincter apparatus and inflammation in lithogenesis. The risk factors for the GD development, the stages of its formation and clinical manifestations are discussed. The treatment of GD depends on the presence of symptoms, disease duration, development of complications, gallbladder functional state, and on the degree of damage to the liver/biliary tract. It has been shown that 25% of GD patients, who develop recurrent clinical symptoms and/or complications, require laparoscopic cholecystectomy. At the same time, patients with asymptomatic GD course, elderly polymorbid patients, as well as patients with the initial GD stages require medical treatment. Pathogenetic approaches to the GD pharmacological treatment with the use of Ursonost and Mebsyn Retard® preparations have been discussed, in particular, the mechanisms of action of the drugs’ active substances, the indications for conducting litholytic therapy, the regimen of drugs’ administration and their safety in the prevention and treatment of symptomatic GD. The principles of dietary nutrition of patients with GD and the preventive role of some products in the regulation of bile rheological properties and gallbladder contractile function have been highlighted. Though minimally invasive surgery remains the most common method of GD treatment, therapeutic treatment with the use of molecules that affect the bile rheological properties, functional state of gallbladder and biliary system, should decrease the number of gastrointestinal complications and reduce the need for cholecystectomy. Therefore, future scientific research should be focused on the development of new preventive strategies for the prevention and treatment of gallstones in the general population and especially in patients with risk factors and comorbidities.

Published: July 2024

Animal welfare in the process of slaughtering animals by the method of removal or without ingestion is still highly debatable. This study aims to systematically review and map the literature in publications on the theme of Animal Welfare in religious slaughter studies. This study used the PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analyses) system in the process of screening articles that were the subject of research. From 375 halal research articles and slaughter rituals indexed by Scopus, 32 articles on animal welfare at the time of religious slaughter were selected and analyzed. The results showed the development of studies on Animal Welfare through the number of publications, authors, countries, fields of science, sources of publications, and articles cited. In this study, two classifications were found, namely, the method of slaughter using stunning and slaughter without prohibited stunning. The study with stunning examines the pain of slaughtered animals, the quality of meat produced at slaughter methods, and ethical considerations and practices of using animals in rituals. The study without stunning examines the effects that occur due to no stunning, the halal of the meat, the treatment of animals during preslaughter without stunning, and stunning after the incision of the Neck Vessels. This study explores some of the latest research development lines from both classifications. This study is expected to be a reference by researchers with the theme of animal welfare when conducting new research on the development of topics on animal welfare during the religious slaughter process.
