APLICAÇÃO DOS PRINCÍPIOS DA PROPORCIONALIDADE E DA RAZOABILIDADE NA DOSIMETRIA DAS SANÇÕES DA LEI DE IMPROBIDADE ADMINISTRATIVA

RESUMO Este artigo tem o objetivo de abordar sobre questões voltadas à aplicabilidade dos Princípios da Proporcionalidade e da Razoabilidade na dosimetria das sanções de improbidade administrativa prescritas na Lei nº 8.429/92. O método abordado para sua composição foi dedutivo, de análise bibliográfica sobre os conceitos de teóricos que discutem em razão desses princípios, da improbidade administrativa e o ponto de vista de alguns autores sobre finalidades desse processo para o balizamento da decisão judicial. Os resultados apontam que são imprescindíveis o uso da razoabilidade e da proporcionalidade como ferramentas fomentadoras do direito fundamental a uma boa administração pública e que cada caso deverá ter análise própria para a aplicação das sanções por improbidade administrativa. PALAVRAS-CHAVE: Dosimetria; Lei de Improbidade Administrativa; Princípios da Proporcionalidade e Razoabilidade. ABSTRACTThis article has the objective of discussing issues related to the application of the Principles of Proportionality and Reasonability in the dosimetry of the penalties of Law no. 8.429/92 of Administrative Improbity. The method used for its composition was the bibliographical analysis on the concepts of theorists who discuss these Principles, Administrative Improbity and the point of view of some authors on the purposes of this process for action. It is concluded that the use of reasonableness and proportionality as essential tools for the fundamental right to good public administration are essential and that each case should have its own analysis for the application of sanctions for administrative improbity .

Polycomb group (PcG) proteins prevent the assembly of abnormal synaptonemal complex structures during meiosis

Copyright © 2022 the Author(s). Published by PNAS. This article is distributed under Creative Commons Attribution-NonCommercial-NoDerivatives License 4.0 (CC BY-NC-ND).The synaptonemal complex (SC) is a proteinaceous scaffold that is assembled between paired homologous chromosomes during the onset of meiosis. Timely expression of SC coding genes is essential for SC assembly and successful meiosis. However, SC components have an intrinsic tendency to self-organize into abnormal repetitive structures, which are not assembled between the paired homologs and whose formation is potentially deleterious for meiosis and gametogenesis. This creates an interesting conundrum, where SC genes need to be robustly expressed during meiosis, but their expression must be carefully regulated to prevent the formation of anomalous SC structures. In this manuscript, we show that the Polycomb group protein Sfmbt, the Drosophila ortholog of human MBTD1 and L3MBTL2, is required to avoid excessive expression of SC genes during prophase I. Although SC assembly is normal after Sfmbt depletion, SC disassembly is abnormal with the formation of multiple synaptonemal complexes (polycomplexes) within the oocyte. Overexpression of the SC gene corona and depletion of other Polycomb group proteins are similarly associated with polycomplex formation during SC disassembly. These polycomplexes are highly dynamic and have a well-defined periodic structure. Further confirming the importance of Sfmbt, germ line depletion of this protein is associated with significant metaphase I defects and a reduction in female fertility. Since transcription of SC genes mostly occurs during early prophase I, our results suggest a role of Sfmbt and other Polycomb group proteins in downregulating the expression of these and other early prophase I genes during later stages of meiosis.R.G.M. is supported by Portuguese national funding through Fundação para a Ciência e a Tecnologia (FCT grant refs.

Surgical aortic valve replacement and patient-prosthesis mismatch a meta-analysis of 108 182 patients

OBJECTIVES: This study sought to evaluate the impact of patient–prosthesis mismatch (PPM) on the risk of perioperative, early-, mid- and long-term mortality rates after surgical aortic valve replacement. METHODS: Databases were searched for studies published until March 2018. The main outcomes of interest were perioperative mortality, 1-year mortality, 5-year mortality and 10-year mortality. RESULTS: The search yielded 3761 studies for inclusion. Of these, 70 articles were analysed, and their data were extracted. The total num- ber of patients included was 108 182 who underwent surgical aortic valve replacement. The incidence of PPM after surgical aortic valve re- placement was 53.7% (58 116 with PPM and 50 066 without PPM). Perioperative mortality [odds ratio (OR) 1.491, 95% confidence interval (CI) 1.302–1.707; P < 0.001], 1-year mortality (OR 1.465, 95% CI 1.277–1.681; P < 0.001), 5-year mortality (OR 1.358, 95% CI 1.218–1.515; P < 0.001) and 10-year mortality (OR 1.534, 95% CI 1.290–1.825; P < 0.001) were increased in patients with PPM. Both severe PPM and moderate PPM were associated with increased risk of perioperative mortality, 1-year mortality, 5-year mortality and 10-year mortality when analysed together and separately, although we observed a higher risk in the group with severe PPM. CONCLUSIONS: Moderate/severe PPM increases perioperative, early-, mid- and long-term mortality rates proportionally to its severity. The findings of this study support the implementation of surgical strategies to prevent PPM in order to decrease mortality rates

Estudio transversal de las estrategias de tratamiento clínico en la fibrilación atrial

BACKGROUND: Despite the high prevalence and clinical importance of atrial fibrillation (AF), there is no Brazilian study about the clinical profile of patients with AF and the most used treatment strategy (heart rhythm control vs. heart rate control) for them. OBJECTIVE: To assess the most used treatment strategy for AF in an outpatient clinic specialized in the management of that disease. In addition, the clinical profile of the population studied was provided. METHODS: Cross-sectional study assessing sequentially, in 167 patients with AF, the most used treatment strategy, as well as their clinical profile. A standardized form was used for data collection. The statistical analysis was performed by using the SPSS® software, version 13.0. RESULTS: In that population at high risk for thromboembolic events (61% had CHADS2 > 2), 54% of the patients had paroxysmal or persistent AF, 96.6% used vitamin K antagonists or acetylsalicylic acid, and 76.6% used beta-blocker (heart rate, 81.2% x heart rhythm, 58.8%; p 2 (60.5% x 39.5%; p = 0.07) and heart valve diseases (25.8% x 11.8%; p = 0.08) was observed in the heart rate control group. CONCLUSION: In that population at high risk for thromboembolic events, the heart rate control strategy was the most used.FUNDAMENTO: A despecho de la elevada prevalencia y importancia clínica de la Fibrilación Atrial (FA), no existen hasta el momento publicaciones brasileñas informando el perfil clínico y la estrategia de tratamiento (control de ritmo vs. control de frecuencia cardíaca) más utilizada en ese universo de pacientes. OBJETIVO: Evaluar la estrategia de tratamiento más empleada en la FA en ambulatorio especializado en el manejo de esa enfermedad. Secundariamente, se buscó describir el perfil clínico de esa población. MÉTODOS: Estudio transversal que evaluó secuencialmente, en 167 portadores de FA, la estrategia de tratamiento más empleada, así como el perfil clínico de esos pacientes. Se utilizó cuestionario estandarizado para recolección de datos. El análisis estadístico fue realizado por medio del software SPSS® versión 13.0. RESULTADOS: En esa población de alto riesgo para eventos tromboembólicos (61% con escore CHADS2 > 2), en que 54% de los individuos presentaban fibrilación atrial paroxística o persistente, 96,6% utilizaban antagonistas de la vitamina K o AAS, y 76,6% hacían uso de betabloqueante (81,2% frecuencia x 58,8% ritmo, p 2 (60,5% x 39,5%; p = 0,07) y valvulopatías (25,8% x 11,8%; p = 0,08) en el segmento de control de la frecuencia. CONCLUSION: En esa población de alto riesgo para eventos tromboembólicos, la estrategia de control de frecuencia cardíaca fue la más empleada.FUNDAMENTO: A despeito de elevada prevalência e importância clínica da Fibrilação Atrial (FA), não existem até o momento publicações brasileiras informando o perfil clínico e a estratégia de tratamento (controle de ritmo vs. controle de frequência cardíaca) mais utilizada nesse universo de pacientes.

Ventricular Septal Rupture after Acute Coronary Syndrome

Objective: Ventricular septal rupture (VSR) is a rare but serious complication of acute myocardial infarction, which occurs in about 0.2 to 0.3% of patients with myocardial ischemia. If early therapy is not initiated, 90% of patients with VSR will die within the first month. This study aimed to evaluate the epidemiological and clinical characteristics of patients with VSR as a mechanical complication of acute myocardial infarction. Methods: A prospective study was conducted among nine patients who presented to the Cardiovascular Emergency Room of Pernambuco with acute coronary syndrome with ST segment elevation and VSR complications. Results: There were five women and 4 men, and the mean age of the patients was 72.5 years. The median time from the onset of the symptoms of acute coronary syndrome with ST segment elevation to the diagnosis of VSR was 3.5 days. Among the nine patients included in the study, three were treated surgically. Of all the patients, including those who underwent corrective surgery, eight patients died, 44.4% (N = 4), in the first four days after AMI. Conclusion: VSR occurs more frequently among elderly patients with multi-arterial involvement, lower wall infarction, and involvement of the right coronary artery. The prognosis is extremely limited, especially in patients who are already admitted to the cardiac emergency room with Killip IV, with > 24 hours of clinical evolution, and do not require surgical correction.Facultad de Ciencias Médica
