Evolução do DSM quanto ao critério categorial de diagnóstico para o distúrbio da personalidade antissocial

OBJETIVO: Realizar um breve percurso sobre o desenvolvimento conceitual de um dos construtos psicológicos de maior evidência nos dias atuais, a saber: o transtorno de personalidade antissocial (TPAS). Especificamente, esse percurso se realiza no sistema categórico proposto pela Associação Americana de Psiquiatria (APA), o Manual Diagnóstico e Estatístico de Distúrbios Mentais (DSM). MÉTODO: Utilizou-se a revisão literária sobre a evolução e a avaliação do construto associada a pesquisas empíricas consultadas nos principais livros e periódicos de reconhecimento internacional na área, tais como: Personality and Individual Differences, Psychological Medicine, Annual Review of Clinical Psychology, Psychological Bulletin, Journal of Abnormal Psychology, Journal of Personality Assessment, International Journal of Offender Therapy and Comparative Criminology, Aggression and Violent Behavior, Handbook of Psychopathy, entre outros. RESULTADO: Observa-se que o diagnóstico do TPAS é baseado nos critérios categóricos e não dimensionais. Isso significa que o sistema não consegue predizer a priori a variabilidade (intensidade) dos traços desse transtorno por ser o DSM desenvolvido no reconhecimento de sintomas e síndromes. CONCLUSÃO: Apesar de o TPAS ter passado por diversas revisões e de apresentar insuficiência taxonômica, ele ainda é amplamente utilizado no diagnóstico e no prognóstico clínico de condições relacionadas ao comportamento social desviante.

Superoxide dismutases and glutaredoxins have a distinct role in the response of Candida albicans to oxidative stress generated by the chemical compounds menadione and diamide

To cope with oxidative stress, Candida albicans possesses several enzymes involved in a number of biological processes, including superoxide dismutases (Sods) and glutaredoxins (Grxs). The resistance of C. albicans to reactive oxygen species is thought to act as a virulence factor. Genes such as SOD1 and GRX2, which encode for a Sod and Grx, respectively, in C. albicans are widely recognised to be important for pathogenesis. We generated a double mutant, Δgrx2/sod1, for both genes. This strain is very defective in hyphae formation and is susceptible to killing by neutrophils. When exposed to two compounds that generate reactive oxygen species, the double null mutant was susceptible to menadione and resistant to diamide. The reintegration of the SOD1 gene in the null mutant led to recovery in resistance to menadione, whereas reintegration of the GRX2 gene made the null mutant sensitive to diamide. Despite having two different roles in the responses to oxidative stress generated by chemical compounds, GRX2 and SOD1 are important for C. albicans pathogenesis because the double mutant Δgrx2/sod1 was very susceptible to neutrophil killing and was defective in hyphae formation in addition to having a lower virulence in an animal model of systemic infection.

JUSTIFYING LIBERAL RETRIBUTIVE JUSTICE: PUNISHMENT, CRIMINALIZATION, AND HOLISTIC RETRIBUTIVISM

ABSTRACT In this article I explore whether liberal retributive justice should be conceived of either individualistically or holistically. I critically examine the individualistic account of retributive justice and suggest that the question of retribution – i.e., whether and when punishment of an individual is compatible with just treatment of that individual – must be answered holistically. By resorting to the ideal of sensitive reasons, a model of legitimacy at the basis of our best normative models of democracy, the article argues that in modern liberal democracies, punishment of an offender A for f is compatible with just treatment of A only if punishment of an individual for f can be legitimate in A's and A's fellow citizens' eyes. Only once retributive justice is understood in this holistic fashion the imposition of punishment can be made compatible with just treatment of individuals.
