Rastreio cognitivo em pacientes com acidente vascular cerebral: um estudo transversal

Objetivo O estudo objetivou-se a fazer um rastreio cognitivo nos pacientes com acidente vascular cerebral (AVC), a fim de determinar pontos de corte de acordo com a idade, escolaridade e grau de comprometimento neurológico. Métodos Foi realizado um estudo transversal no qual participaram 109 pacientes ambulatoriais, sendo 61 homens, com média da idade de 59 anos (± 11), média do tempo de escolaridade de 5 anos (± 4) e do tempo de sequela de 16 meses (± 14). Os pacientes foram avaliados por meio do Miniexame do Estado Mental (MEEM) e pela National Institute of Health Stroke Scale. Os dados foram analisados pela regressão linear múltipla (stepwise forward). Resultados Verificou-se que as variáveis grau de comprometimento neurológico, idade e escolaridade contribuíram significativamente para o valor global do MEEM e explicaram a variância do estado cognitivo (R2 ajustado = 0,24). Cada aumento do comprometimento neurológico representou diminuição de 0,456 no escore do MEEM. Quanto maior a idade, ocorreu uma diminuição de 0,202 no MEEM, e à medida que diminui o tempo de escolaridade, houve uma diminuição de 0,190 no MEEM. Os pontos de corte variaram de 14 a 22 de acordo com o grau de comprometimento neurológico, idade e escolaridade. Conclusão Os resultados apontaram que, por meio do rastreio positivo de déficit cognitivo, foram encontrados pontos de corte associados ao comprometimento neurológico, necessitando também serem ajustados pela idade e escolaridade, sugerindo que essas associações sejam preferencialmente levadas em consideração na planificação da reabilitação neuropsicológica dos pacientes com AVC.

Silent citizens: on silence and silencing in journalism

Constructivist approaches to journalism, which have dominated the field for most of the second half of the 20th century, underline how selection and ranking processes produce representations and interpretations of social reality. Theoretical perspectives such as agenda-setting or framing have been pointing to the ways production of news messages are shaped and issues are defined. Research inspired by these contributions does however seem to keep in an area of relative shade not so much what is said and published but what is not selected: the unsaid, the withheld, the untold of journalism. The reality that remains in silence, for not being noticed or for being silenced, is the reverse of the coin of what is made visible. In this paper, it is suggested that this situation opens up the debate to a relatively unknown continent, which could contribute to the larger discussion on the current crisis in journalism. It is our contention that ‘the untold’ might be at the confluence of different levels: the journalistic agenda-setting by news sources; the deterioration of working conditions of journalists, compromising the investigation; and the social capital asymmetries from important segments of the population, hampering the public word (speech?) and the right to communicate. In order to build a comprehensive picture of the potentialities and contradictions of journalism from the unsaid side, we would put forward the outline of a typology of journalism's silences, with particular emphasis on some aspects of "discursive discrimination" (Boréus, 2006), on the one hand, and on citizen silence in the process of journalistic production, on the other hand.

A possible contribution to improving the therapeutic potentials of Babor's Typology of Alcohol Dependent Patients

ABSTRACT Objective The objective of this study was to replicate Babor's Typology and to explore clinical features related to personality traits that may underlie this classification, in order to improve its therapeutic possibilities. Methods Observational prospective study on a group of 273 male alcoholics. After a replication of Babor's variables, Cluster Analysis, Chi-Square – applied on clinical variables related to a Lappda Tipology – and Kappa tests were performed. Results The study identified two distinct clusters that held similar features to those described for the Type A/Type B classification. Besides presenting a lower socio-economic situation, Cluster 2 patients were associated with higher vulnerability and severe clinical features and also differed from Cluster 1 in their response to treatment. These replicated clusters retained connections and also differences in relation to the variables derived from the Lappda Typology. Conclusion Considering that each of the two replicated clusters seem to be associated to different personality traits – according to their correlations to the affective, cognitive and behavioral dimensions brought forward by the Lappda Typology – it is acceptable that this study may contribute to the development of more comprehensive and effective therapeutic strategies specifically tailored to target more specific personality traits of these subgroups of alcoholic patients.

Introduction to special Issue: future priorities in European media and communication research

(Excerto) The European Journal of Communication seeks to present the best in current research in the broad field of media and communication research. Irregularly, we seek to take stock by inviting a small group of leading scholars to present their work at a symposium on a common theme, which then forms the basis for a Special Issue of the Journal. In 2014, the European Science Foundation (ESF) published one of their ‘Forward Looks’ entitled Media in Europe: New Questions for Research and Policy. We subsequently invited several of the Forward Look’s authors to meet and discuss their work with us at a symposium hosted by the European University Cyprus, and the discussion and revised papers that resulted are published here.
