Cardiac Magnetic Resonance as an Etiological Diagnosis Tool in Recovered Sudden Cardiac Death or Unstable Ventricular Arrhythmia Patients. / Ressonância Magnética Cardíaca como Ferramenta Diagnóstica Etiológica em Pacientes Recuperados de Morte Súbita Cardíaca ou Arritmias Ventriculares Instáveis.

BACKGROUND: Cardiac magnetic resonance (CMR) has an increasing diagnostic relevance in survivors of sudden cardiac death (SCD) or unstable ventricular arrhythmia (UVA) in developed countries. OBJECTIVE: To evaluate retrospectively the additional role of CMR in a developing country where few resources are available, and should be used more effectively. METHODS: The study included SCD or UVA survivors admitted between 2009 and 2019 at a tertiary academic institution referred to CMR. Demographic, clinical, and laboratory data were collected from the medical records. CMR images and reports were reviewed and their impact on the final etiological diagnosis was determined. A descriptive analysis was performed and p<0.05 established as significant. RESULTS: Sixty-four patients, 54.9±15.4 years old, and 42 (71.9%) males. Most events (81.3%) were out of the hospital and ventricular tachycardia was the most common rhythm. Cardiovascular medications were previously used by 55 patients, and beta-blockers were the most used medications (37.5%). Electrocardiogram had electrical inactive areas in 21.9% and all of them had fibrosis at CMR. Mean left ventricular ejection fraction (LVEF) was 44±14%, with 60.9% ≤50% and only 29.7% ≤35%. Late gadolinium enhancement was identified in 71.9%, with a transmural pattern in 43.8%. Chagas cardiomyopathy was the most common etiology (28.1%), followed by ischemic cardiomyopathy (17.2%). Among 26 without a previously identified etiology, CMR could define it (15 patients - 57%). CONCLUSION: In accordance with previous studies in developed countries, CMR was capable of increasing etiological diagnosis and identifying the arrhythmogenic substrate, allowing better care in half of the underdiagnosed patients.

FUNDAMENTO: A ressonância magnética cardíaca (RMC) tem relevância diagnóstica crescente em sobreviventes de morte súbita cardíaca (MSC) ou arritmia ventricular instável (AVI) em países desenvolvidos. OBJETIVO: Procuramos avaliar retrospectivamente o papel adicional da RMC em um país em desenvolvimento com poucos recursos disponíveis e que pode direcionar um uso mais eficaz desses recursos. MÉTODOS: Foram incluídos sobreviventes de MSC ou AVI admitidos entre 2009 e 2019 em uma instituição acadêmica terciária após a realização de RMC. Dados demográficos, clínicos e laboratoriais foram coletados dos prontuários. Imagens e laudos de RMC foram analisados e o impacto disso no diagnóstico etiológico final foi afirmado. Realizou-se análise descritiva e definiu-se p<0,05 como significativo. RESULTADOS: Sessenta e quatro pacientes, 54,9±15,4 anos, sendo 42 (71,9%) do sexo masculino. A maioria dos eventos (81,3%) foi extra-hospitalar e a taquicardia ventricular foi o ritmo mais comum. Medicamentos cardiovasculares foram utilizados anteriormente por 55 pacientes, sendo os betabloqueadores os medicamentos mais utilizados (37,5%). O eletrocardiograma apresentava áreas elétricas inativas em 21,9% e todos apresentavam fibrose na RMC. A média da fração de ejeção do ventrículo esquerdo (FEVE) foi de 44±14%, com 60,9% ≤50% e apenas 29,7% ≤35%. Identificou-se realce tardio com gadolínio em 71,9%, com padrão transmural em 43,8%. A miocardiopatia chagásica foi a etiologia mais comum (28,1%), seguida da miocardiopatia isquêmica (17,2%). Entre 26 sem etiologia previamente identificada, foi possível definir com RMC (15 pacientes - 57%). CONCLUSÃO: De acordo com estudos anteriores em países desenvolvidos, a RMC foi capaz de aumentar o diagnóstico etiológico e identificar o substrato arritmogênico, permitindo melhor atendimento em metade dos pacientes subdiagnosticados.

Association of left ventricular abnormalities with incident cerebrovascular events and sources of thromboembolism in patients with chronic Chagas cardiomyopathy.

BACKGROUND: Although Chagas cardiomyopathy is related to thromboembolic stroke, data on risk factors for cerebrovascular events in Chagas disease is limited. Thus, we assessed the relationship between left ventricular (LV) impairment and cerebrovascular events and sources of thromboembolism in patients with Chagas cardiomyopathy. METHODS: This retrospective cohort included patients with chronic Chagas cardiomyopathy who underwent cardiovascular magnetic resonance (CMR). CMR was performed with a 1.5 T scanner to provide LV volumes, mass, ejection fraction (LVEF), and myocardial fibrosis. The primary outcome was a composite of incident ischemic cerebrovascular events (stroke or transient ischemic attack-TIA) and potential thromboembolic sources (atrial fibrillation (AF), atrial flutter, or intracavitary thrombus) during the follow-up. RESULTS: A total of 113 patients were included. Median age was 56 years (IQR: 45-67), and 58 (51%) were women. The median LVEF was 53% (IQR: 41-62). LV aneurysms and LV fibrosis were present in 38 (34%) and 76 (67%) individuals, respectively. The median follow-up time was 6.9 years, with 29 events: 11 cerebrovascular events, 16 had AF or atrial flutter, and two had LV apical thrombosis. In the multivariable model, only lower LVEF remained significantly associated with the outcomes (HR: 0.96, 95% CI: 0.93-0.99). Patients with reduced LVEF lower than 40% had a much higher risk of cerebrovascular events and thromboembolic sources (HR: 3.16 95% CI: 1.38-7.25) than those with normal LVEF. The combined incidence rate of the combined events in chronic Chagas cardiomyopathy patients with reduced LVEF was 13.9 new cases per 100 persons-year. CONCLUSIONS: LV systolic dysfunction is an independent predictor of adverse cerebrovascular events and potential sources of thromboembolism in patients with chronic Chagas cardiomyopathy.

Congenitally Corrected Transposition of the Great Arteries in the Adult

ABSTRACT Introduction: Congenitally corrected transposition of the great arteries (CCTGA) is a rare anomaly. Current data available regarding adult cases is derived from small series, information simultaneously presented in pediatric publications, and one classical multicenter study. This review, not aimed to exhaust the subject, has the purpose to examine the literature addressing presentation, diagnostic methodology, and management of afflicted adult patients. Methods: A comprehensive search was undertaken in three major databases (PubMed, Cochrane, SciELO), using the keywords "congenitally corrected transposition of the great arteries" and "adults". Relevant articles in English, Spanish, and Portuguese were extracted and critically appraised in this review. Steps for study selection were: (1) identification of titles of records through databases searching, (2) removal of duplicates, (3) screening and selection of abstracts, (4) final inclusion in the study. Results: Four hundred sixty-five publications on CCTGA in adult patients were retrieved, and 166 were excluded; 299 studies were used for this review including 76 full-text articles, 70 studies related to general aspects of the subject, and, due to the small number of publications, 153 case reports. Sixty-one articles referring to combined experiences in pediatric and adult patients and judged to be relevant, but retrieved from another sources, were also included. Conclusion: Albeit clinical presentation and diagnostic criteria have been well stablished, there seems to be room for discussion related to clinical and surgical management of CCTGA in adults. Considering the rarity of the disease, well designed multicenter studies may provide answers.

Electrocardiogram abnormalities in chronic Chagas cardiomyopathy correlate with scar mass and left ventricular dysfunction as assessed by cardiac magnetic resonance imaging.

Electrocardiographic (ECG) abnormalities are frequently identified in Chronic Chagas cardiomyopathy (CCC) patients and advanced abnormalities are related to a worse prognosis. Cardiac Magnetic Resonance (CMR) can precisely assess ventricular systolic dysfunction and quantify myocardial fibrosis (MF), both identified as prognostic factors. We sought to investigate if ECG abnormalities in CCC patients were associated with more severe myocardial involvement as evaluated by CMR. METHODS: CCC patients with 12­lead ECG and CMR closely obtained were included. ECG analysis evaluated rhythm, presence, and type of intraventricular conduction disturbances (IVCD) and, ventricular premature beats (VPB). CMR short-axis cine and late gadolinium enhancement images were evaluated to obtain left and right ventricular ejection fractions and MF mass, respectively. Statistical significance was set in 5%. RESULTS: 194 CCC patients (98 women, 56 ± 14 years) were evaluated, and no IVCD was detected in 71. The most common IVCD was the association of right bundle branch block and left anterior fascicular block (RBBB+LAFB) in 58 patients, followed by isolated RBBB in 34, isolated LAFB in 17, and left bundle branch block (LBBB) in 14 patients. Of patients with no IVCD, 63% had MF and the burden of fibrosis (no IVCD - 7.4 ± 8.6%; RBBB - 6.6 ± 6.5%; p = 1.00), as well as left ventricular ejection fraction (LVEF) (no IVCD - 52 ± 14%; RBBB - 55 ± 10%; p = 1.00) were similar to patients with isolated RBBB. Left conduction system impairment was associated with lower LVEF (LAFB - 39 ± 15%; RBBB+LAFB- 41 ± 15%; and LBBB - 35 ± 15%; p < 0.001) and more MF (RBBB+LAFB - 12.2 ± 10.4%; LBBB - 10.6 ± 7.5%; and LAFB - 12.0 ± 7.0%; p < 0.001). The univariable model showed that the presence of MF was related to RBBB+LAFB (OR 5.0; p = 0.001) and VPB (OR 6.3; p = 0.014). After adjustment for age, gender, and different risk factors in a multivariable model, the same findings were still significantly related to CMR myocardial fibrosis (RBBB+LAFB OR 5.0; p = 0.002 / VPB OR 6.9; p = 0.015). CONCLUSIONS: ECG without IVCD does not exclude serious cardiac abnormalities in CCC, and isolated RBBB seems to have a benign course. The presence of VPB and left branch conduction impairment, especially LAFB associated with RBBB, indicate a more severe cardiac involvement.

Identification of Antibacterial Peptide Candidates Encrypted in Stress-Related and Metabolic Saccharomyces cerevisiae Proteins.

The protein-rich nature of Saccharomyces cerevisiae has led this yeast to the spotlight concerning the search for antimicrobial peptides. Herein, a <10 kDa peptide-rich extract displaying antibacterial activity was obtained through the autolysis of yeast biomass under mild thermal treatment with self-proteolysis by endogenous peptidases. Estimated IC50 for the peptide pools obtained by FPLC gel filtration indicated improved antibacterial activities against foodborne bacteria and bacteria of clinical interest. Similarly, the estimated cytotoxicity concentrations against healthy human fibroblasts, alongside selective indices ≥10, indicates the fractions are safe, at least in a mixture format, for human tissues. Nano-LC-MS/MS analysis revealed that the peptides in FPLC fractions could be derived from both induced-proteolysis and proteasome activity in abundant proteins, up-regulated under stress conditions during S. cerevisiae biomass manufacturing, including those coded by TDH1/2/3, HSP12, SSA1/2, ADH1/2, CDC19, PGK1, PPI1, PDC1, and GMP1, as well as by other non-abundant proteins. Fifty-eight AMP candidate sequences were predicted following an in silico analysis using four independent algorithms, indicating their possible contribution to the bacterial inactivation observed in the peptides pool, which deserve special attention for further validation of individual functionality. S. cerevisiae-biomass peptides, an unconventional but abundant source of pharmaceuticals, may be promissory adjuvants to treat infectious diseases that are poorly sensitive to conventional antibiotics.

Avaliação da composição de cardápios de escolas públicas do município de São Paulo utilizando o índice de qualidade da Coordenação de Segurança Alimentar e Nutricional e o método de análise qualitativa das preparações do cardápio / Evaluation of the composition of public-school menu in the municipality of São Paulo using the quality index of the Food and Nutrition Security Coordination and the method of qualitative analysis of menu preparations

Introdução: Na infância, a escola tem importante impacto na formação de hábitos alimentares. A alimentação qualitativa e quantitativamente adequada é essencial para garantir o crescimento e o desenvolvimento e, nesse cenário, o Programa Nacional de Alimentação Escolar tem por objetivo realizar ações de educação alimentar e nutricional e oferecer refeições que garantam as necessidades nutricionais durante o período letivo. Objetivo: Avaliar quanti-qualitativamente a composição dos cardápios do Programa de Alimentação Escolar da rede municipal de São Paulo. Métodos: A coleta de dados foi realizada nos meses de agosto a outubro de 2019, por meio dos cardápios disponibilizados na plataforma eletrônica "Prato Aberto", publicada sob responsabilidade da Secretaria Municipal de Educação de São Paulo nos meses de agosto a outubro de 2019, para as Escolas Municipais de Ensino Fundamental. Os cardápios foram avaliados por sorteio das escolas de acordo com sua localização. Resultados: A média de pontuação total demonstra que todos os cardápios avaliados foram classificados como adequados; entretanto, ao analisar detalhadamente os resultados mensais para cada escola, foi possível notar o impacto das diferentes formas de gestão, compras de alimentos e planejamento dos cardápios. Conclusão: Os cardápios foram avaliados positivamente frente às duas ferramentas e estavam adequados quanto às recomendações do PNAE, embora houvesse pontos a serem melhorados, sobretudo quanto à alta previsão de oferta de alimentos restritos. (AU)

Introduction: In childhood, school has an important impact on the formation of eating habits. Qualitatively and quantitatively adequate food is essential to ensure growth and development and, in this scenario, the National School Feeding Program aims to carry out food and nutrition education actions and offer meals that guarantee nutritional needs during the school term. Objective: To quantitatively and qualitatively evaluate the composition of the menus in the School Meals Program of the municipal network of São Paulo. Methods: Data collection was carried out from August to October 2019, using menus available on the electronic platform "Prato Aberto", published under the responsibility of the Municipal Education Department of São Paulo from August to October 2019, for Municipal Elementary Schools. The menus were evaluated by drawing lots of schools according to their location. Results: The average total score demonstrates that all evaluated menus were classified as adequate; however, when analyzing in detail the monthly results for each school, it was possible to notice the impact of different forms of management, food purchases and menu planning. Conclusion: The menus were positively evaluated against the two tools and were adequate in terms of the PNAE recommendations, although there were points to be improved, especially regarding the high forecast of restricted food supply.

Towards urban resilience through Sustainable Drainage Systems: A multi-objective optimisation problem.

The necessity of incorporating a resilience-informed approach into urban planning and its decision-making is felt now more than any time previously, particularly in low and middle income countries. In order to achieve a successful transition to sustainable, resilient and cost-effective cities, there is a growing attention given to more effective integration of nature-based solutions, such as Sustainable Drainage Systems (SuDS), with other urban components. The experience of SuDS integration with urban planning, in developed cities, has proven to be an effective strategy with a wide range of advantages and lower costs. The effective design and implementation of SuDS requires a multi-objective approach by which all four pillars of SuDS design (i.e., water quality, water quantity, amenity and biodiversity) are considered in connection to other urban, social, and economic aspects and constraints. This study develops a resilience-driven multi-objective optimisation model aiming to provide a Pareto-front of optimised solutions for effective incorporation of SuDS into (peri)urban planning, applied to a case study in Brazil. This model adopts the SuDS's two pillars of water quality and water quantity as the optimisation objectives with its level of spatial distribution as decision variables. Also, an improved quality of life index (iQoL) is developed to re-evaluate the optimal engineering solutions to encompass the amenity and biodiversity pillars of SuDS. Rain barrels, green roofs, bio-retention tanks, vegetation grass swales and permeable pavements are the suitable SuDS options identified in this study. The findings show that the most resilient solutions are costly but this does not guarantee higher iQoL values. Bio-retention tanks and grass swales play effective roles in promotion of water quality resilience but this comes with considerable increase in costs. Permeable pavements and green roofs are effective strategies when flood resilience is a priority. Rain barrel is a preferred solution due to the dominance of residential areas in the study area and the lower cost of this option.

Missed opportunities in the way medical schools evaluate the ethical domain in clerkship rotations.

BACKGROUND: Several lines of evidence indicate that medical schools have been failing to adequately nurture empathy and the ethical dimension in their graduates, the lack of which may play a central role in the genesis of medical errors, itself a major source of avoidable deaths, incapacity and wasted resources. It has been widely proposed that medical schools should adopt evaluation strategies as a means to promote a culture of respectful relationships. However, it is not clear if evaluation strategies in medical schools have addressed key domains related to that aim, such as ethics, through the perspective of their students. Hence, we conducted a national survey of instruments used by Brazilian medical schools to assess clerkship rotations from the perspective of students, with a main focus on the ethical domain. METHODS: The authors invited 121 randomly selected institutions to participate in the study. Key informants answered a questionnaire about clerkship rotations and sent copies of any instrument used to assess the quality of clerkship rotations according to the students' perspectives. RESULTS: Twenty-six (53%) of 49 participating schools used an instrument to assess the quality of clerkship rotations according to the perspective of students. Just 13 (27%) schools had instruments containing at least one question encompassing the ethical domain. Only 2 (4%) schools asked students specifically about the occurrence of any negative experience concerning the ethical domain during rotations. Merely 1 (2%) school asked students about having witnessed patient mistreatment and none asked about mistreatment against students themselves. CONCLUSIONS: There are several missed opportunities in the way medical schools assess the quality of clerkship rotations regarding the ethical domain. Closing the gap between usual institutional discourses regarding ethics and how that dimension is assessed within clerkship rotations might represent an important step towards the improvement of medical education and healthcare systems.

Hands Up! Atypical Defensive Reactions in Heavy Players of Violent Video Games When Exposed to Gun-Attack Pictures.

Threatening cues and surrounding contexts trigger specific defensive response patterns. Posturography, a technique for measuring postural strategies, has been used to evaluate motor defensive reactions in humans. When exposed to gun pointed pictures, humans were shown to exhibit an immobility reaction. Short and long-term exposure to violent video games was shown to be a causal risk factor for increased violent and aggressive behavior. Assaultive violence with a gun is a major trigger for motor defensive reactions, and post-traumatic stress disorder (PTSD) is the most characteristic psychiatric sequelae. Recent studies point to links between PTSD symptoms and emotional shortfalls in non-clinical trauma-exposed samples. The present study investigated defensive reactions to gun threat and PTSD symptoms in heavy players of violent video games compared to non-players. Male university students were screened according to use of violent video games and divided in three groups: non-players, moderate players, and heavy players. Stimuli were pictures depicting a man pointing a gun directed at the participant. In matched control pictures, non-lethal objects replaced the gun. Posturography was recorded and PTSD symptoms were assessed. When exposed to the threat pictures, non-players exhibited the expected reduction in amplitude of body sway (immobility), heavy players presented atypical augmented amplitude of body sway, and moderate players showed intermediate reactivity. Heavy players presented a significant distinct reaction compared to non-players. They also scored significantly higher in PTSD symptoms than non-players. Disadvantageous defensive reactions and higher vulnerability to PTSD symptoms, revealed in the present study, add to other shortcomings for heavy players.

Translation and cultural adaptation of the Pediatric Eosinophilic Esophagitis Symptom Score (PEESS v2 0) / Tradução e adaptação cultural da Pediatric Eosinophilic Esophagitis Symptom Score (PEESS v2 0)

Abstract Objectives: To translate and culturally adapt the Pediatric Eosinophilic Esophagitis Symptom Score (version 2.0), a tool used to assess pediatric eosinophilic esophagitis symptoms reported by patients and/or their parents/caregivers. Methods: The Pediatric Eosinophilic Esophagitis Symptom Score was translated through the following stages: initial translation, back-translation, and consensus of independent reviewers through the Delphi technique. The pre-final version of the Pediatric Eosinophilic Esophagitis Symptom Score was applied to five 8-to-18-year-old patients and to ten parents of two-to-18-year-old patients from an outpatient pediatric gastroenterology service (pre-test). Results: During the translation process, no translations presenting with difficult consensus in the review process or grammar inconsistencies were observed. During the pre-test, difficulties in comprehension of some unconventional terms, e.g., "náusea", were observed. Adverbs of frequency, such as "quase nunca" were also identified as being of difficult understanding by patients and parents, and the substitution by the term "raramente" was suggested. Such difficulties may be inherent to the pediatric age group. Age 8 years or above should be considered adequate for the self-reporting of symptoms. Conclusions: The study presents the Brazilian version of the Pediatric Eosinophilic Esophagitis Symptom Score, which is adapted to the Brazilian culture. This version may be introduced as a clinical and research tool for the assessment of patients with esophagic disease symptoms. The Pediatric Eosinophilic Esophagitis Symptom Score is a breakthrough in the evaluation of symptoms of pediatric eosinophilic esophagitis, since it reinforces the importance of self-reporting by patients who experience this disease.

Resumo Objetivo: Traduzir e adaptar culturalmente a Pediatric Eosinophilic Esophagitis Symptom Score (versão 2.0), um instrumento usado para identificar os sintomas relatados pelos pacientes ou seus pais/responsáveis para a avaliação da esofagite eosinofílica pediátrica. Método: Realizamos o processo de tradução a partir da tradução inicial, retrotradução, seguida da etapa de obtenção de consenso por revisores independentes por meio da técnica Delphi. Aplicamos a versão pré-final a cinco pacientes de 8 a 18 anos e dez pais de pacientes de 2 a 18 anos no Serviço de Gastroenterologia Pediátrica (pré-teste). Resultados: No processo de tradução, não encontramos traduções de difícil consenso no processo de revisão ou discordâncias gramaticais. No pré-teste, identificamos dificuldades de entendimento de termos pouco convencionais, como "náusea", com sugestão de substituição para o termo "enjoo". Outra dificuldade encontrada relacionou-se aos advérbios de frequência da escala, como, por exemplo, "quase nunca", foi sugerida a substituição pelo termo "raramente". Essas dificuldades podem ser inerentes à faixa etária pediátrica. A idade dos pacientes a partir de oito anos deve ser considerada adequada para o uso de escores de autorrelato. Conclusões: A tradução do escore de sintomas da esofagite eosinofílica pediátrica produziu uma escala adaptada à cultura brasileira, que poderá ser introduzida como instrumento de investigação clínica e de pesquisa em pacientes com sintomas sugestivos de doenças esofágicas. É um importante avanço na avaliação dos sintomas, já que valoriza o relato dos próprios pacientes que convivem com essa doença.

Left Ventricular Scar and Prognosis in Chronic Chagas Cardiomyopathy.

BACKGROUND: Patients with chronic Chagas cardiomyopathy (CCC) have pronounced myocardial fibrosis, which may predispose to sudden cardiac death, despite well-preserved global left ventricular (LV) systolic function. Cardiac magnetic resonance can assess myocardial fibrosis by late gadolinium enhancement (LGE) sequences. OBJECTIVES: This prospective study evaluated if the presence of scar by LGE predicted hard adverse outcomes in a cohort of patients with CCC. METHODS: A prospective cohort of 140 patients with CCC (52.1% female; median age 57 years [interquartile range: 45 to 67 years]) were included. Cardiac magnetic resonance cine and LGE imaging were performed at enrollment with a 1.5-T scanner. The primary endpoint was the combination of cardiovascular death and sustained ventricular tachycardia. The secondary endpoint was the combination of cardiovascular death, sustained ventricular tachycardia, or cardiovascular hospitalization during follow-up. RESULTS: After a median of 34 months (interquartile range: 24 to 49 months) of follow-up, 11 cardiovascular deaths, 3 episodes of sustained ventricular tachycardia, and 20 cardiovascular hospitalizations were recorded. LGE scar was present in 71.4% of the patients, with the lateral, inferolateral, and inferior walls most commonly affected. Patients with positive LGE had lower LV ejection fraction and higher LV end-diastolic volume and LV mass than patients without LGE. No difference in other cardiovascular risk factors was noted. Patients with scar had higher event rates compared with those without scar for the primary (p = 0.043) and the secondary (p = 0.016) endpoint. In multivariable analysis, age and LGE area were related to primary outcome; age and lower LV ejection fraction were related to the secondary outcome. The pattern of LGE myocardial fibrosis was transmural, focal, or diffuse scar in approximately one-third of patients with positive LGE, and no pattern was specifically related to outcomes. CONCLUSIONS: In patients with CCC, presence of scar by LGE is common and is strongly associated with major adverse outcomes.

Pergunta-se pelas condições que possibilitam essa articulação entre o discurso dos direitos humanos, que critica a lógica punitiva, e o uso da punição aos violadores. Partiremos dos estudos de Nietzsche, Foucault e Wacquant acerca da ideologia da punição, penalização e criminalização, para relacioná-los a produções (sobretudo de autores brasileiros) da área da criminologia que abordam e questionam esses paradoxos. Aponta-se como uma das reflexões decorrentes do estudo que, na atualidade, as lutas e os movimentos sociais do campo dos direitos humanos estão em crescente judicialização, decorrente desta lógica que criminaliza as violações, colocando-as no campo estatal, judiciário e policial.

El objetivo de este trabajo es reflexionar a cerca de la lógica punitiva de las luchas por el reconocimiento y por los derechos humanos. Nos preguntamos sobre las condiciones que posibilitan la articulación entre el discurso de los derechos humanos - que critica la lógica punitiva - y el uso de la punición aplicada a los violadores. Como base para esa reflexión, son abordados los estudios de Nietzsche, Foucault y Wacquant, que tratan sobre la ideología de la punición, penalización y criminalización, para después relacionarlos a las producciones, sobre todo de autores brasileños, que cuestionan la paradoja de las luchas por reconocimiento y derechos humanos. Se señala como una de las reflexiones resultantes de los estudios que, en la actualidad, las luchas y los movimientos sociales del campo de los derechos humanos están en creciente judicialización, resultante de esta lógica que criminaliza las violaciones, colocándolas en los campos estatal, judicial y policial.

The objective of this study is to reflect on the punitive logic inherent in the context of the struggle for the recognition of human rights. It questions the conditions that make possible the articulation between the discourse of human rights, which criticizes punitive logic, and the use of punishment for violators. The theoretical framework for this reflection is based on studies by Nietzsche, Foucault and Wacquant, regarding the ideology of punishment, penalization and criminalization to relate it to the production (most of them by Brazilian authors) who question the paradoxes in the struggle for the recognition of human rights. One of the reflections made by this study points that, today, the struggles and the social movements in the human rights field are going through an increasing judicialization, due to this logic which criminalizes the violations, placing them in the state, judiciary and police field.

L'objectif de cette étude est de faire réfléchir sur la logique punitive dans le contexte des luttes par reconnaissance et les droits de l'homme. Nous nous demandons pour les conditions qui permettent cette articulation entre le discours des droits de l'homme, qui critique la logique punitive, et l'utilisation de la punition aux violateurs. Nous allons partir des études de Nietzsche, Foucault et Wacquant à propos de l'idéologie de la punition, pénalité et la criminalisation, pour faire un rapport entre eux et les productions (principalement des auteurs brésiliens) du domaine de la criminologie qui abordent et questionnent ces paradoxes. Il est signalé comme l'une des réflexions resultant de l'étude que, aujourd'hui, les luttes et les movements sociaux dans le domaine des droits de l'homme sont en augmentation de la judiciarisation, en raison de cette logique qui criminalise les violations, les plaçant dans les domaines étatique, judiciaire et policier.

Why medical schools are tolerant of unethical behavior.

The exposure to unethical and unprofessional behavior is thought to play a major role in the declining empathy experienced by medical students during their training. We reflect on the reasons why medical schools are tolerant of unethical behavior of faculty. First, there are barriers to reporting unprofessional behavior within medical schools including fear of retaliation and lack of mechanisms to ensure anonymity. Second, deans and directors do not want to look for unethical behavior in their colleagues. Third, most of us have learned to take disrespectful circumstances in health care institutions for granted. Fourth, the accreditation of medical schools around the world does not usually cover the processes or outcomes associated with fostering ethical behavior in students. Several initiatives promise to change that picture.

Sudden Cardiac Death in Brazil: A Community-Based Autopsy Series (2006-2010) / Morte Súbita Cardíaca no Brasil: Análise dos Casos de Ribeirão Preto (2006-2010)

Background: Sudden cardiac death (SCD) is a sudden unexpected event, from a cardiac cause, that occurs in less than one hour after the symptoms onset, in a person without any previous condition that would seem fatal or who was seen without any symptoms 24 hours before found dead. Although it is a relatively frequent event, there are only few reliable data in underdeveloped countries. Objective: We aimed to describe the features of SCD in Ribeirão Preto, Brazil (600,000 residents) according to Coroners’ Office autopsy reports. Methods: We retrospectively reviewed 4501 autopsy reports between 2006 and 2010, to identify cases of SCD. Specific cause of death as well as demographic information, date, location and time of the event, comorbidities and whether cardiopulmonary resuscitation (CPR) was attempted were collected. Results: We identified 899 cases of SCD (20%); the rate was 30/100000 residents per year. The vast majority of cases of SCD involved a coronary artery disease (CAD) (64%) and occurred in men (67%), between the 6th and the 7th decades of life. Most events occurred during the morning in the home setting (53.3%) and CPR was attempted in almost half of victims (49.7%). The most prevalent comorbidity was systemic hypertension (57.3%). Chagas’ disease was present in 49 cases (5.5%). Conclusion: The majority of victims of SCD were men, in their sixties and seventies and the main cause of death was CAD. Chagas’ disease, an important public health problem in Latin America, was found in about 5.5% of the cases. .

Fundamento: Morte súbita cardíaca (MSC) é um evento súbito e inesperado, de causa cardiovascular, que ocorre em menos de uma hora após o início dos sintomas, em indivíduo sem qualquer condição clínica prévia potencialmente fatal ou assintomático nas últimas 24 horas antes do óbito, em caso de morte não testemunhada. Apesar de ser um evento relativamente frequente, há poucos dados confiáveis na literatura sobre países em desenvolvimento. Objetivo: Descrever as características da MSC em Ribeirão Preto (SP 600.000 habitantes) baseando-se nos relatórios de autopsias do Serviço de Verificação de Óbitos do Interior. Métodos: Foram revisados retrospectivamente 4.501 relatórios de autopsias entre 2006 e 2010, para identificar casos de MSC. Foram coletados dados como causa específica do óbito, características demográficas e comorbidades das vítimas, data, local e hora do evento, e se foram realizadas manobras de ressuscitação cardiopulmonar (RCP). Resultados: Foram identificados 899 casos de MSC (20%; razão 30/100.000 habitantes por ano). A principal causa de MSC foi doença arterial coronariana (DAC - 64%), acometendo homens (67%) entre a sexta e a sétima década de vida. A maior parte dos eventos ocorreu durante a manhã, no domicílio (53,3%), e a RCP foi realizada em quase metade das vítimas (49,7%). A comorbidade mais prevalente foi hipertensão arterial sistêmica (57,3%). Doença de Chagas foi detectada em 49 casos (5,5%). Conclusão: A maioria dos casos de MSC ocorreu por DAC em homens entre a sexta e a sétima década de vida. Doença de Chagas, um importante problema de saúde pública na América Latina, foi detectada em 5,5% dos casos. .
