This study investigated cardiovascular reactivity of hypertensive adults during periods of emotional stress. Two types of instructions were given at different moments, to the same subject, either to express or to suppress feelings during role-play. Expressing, but not inhibiting, emotions elicited significantly higher reactivity during responding to negative scenes, followed by responding during the positive interactions. Blood pressure increases in both expressing and inhibiting conditions, were also found during the instruction periods. Results indicated that socially demanding situations represent a stressor whose effects may vary depending on whether or not respondents regulate expression of emotions. It is suggested that the difficulty in expressing emotions found in some hypertensive individuals may have the function of controlling or reducing blood pressure reactivity. Keywords: cardiovascular reactivity, hypertension, interpersonal stress, expression of emotions, inhibition of emotionsEn este estudio investigamos la reactividad cardiovascular de adultos hipertensos durante períodos de estrés emocional. Se dieron dos tipos de instrucciones en diferentes momentos al mismo sujeto: que expresara o que suprimiera sus emociones durante un juego de roles. Al expresar, pero no al inhibir, las emociones elicitaron reactividad significativamente más alta cuando los sujetos respondían a escenas negativas, seguido de su respuesta durante interacciones positivas. También se encontraron incrementos en la presión sanguínea durante los períodos de instrucción, tanto en las condiciones de expresión como en las de inhibición. Los resultados indicaron que las situaciones socialmente exigentes representan un estresor cuyos efectos pueden variar en función de si los sujetos regulan la expresión de sus emociones. Se sugiere que la dificultad en la expresión de emociones encontrada en algunos individuos hipertensos puede tener la función de controlar o reducir la reactividad de la presión sanguínea.

Resumo O Prospecto Aurora localiza-se na região nordeste do Brasil (Estado do Ceará), na porção central da Província Borborema, no Domínio da Zona Transversal e possui idade meso a neoproterozoica, ao longo do Lineamento Patos. As ocorrências de cobre de Aurora são hospedadas por rochas metavulcano-sedimentares do Grupo Cachoeirinha. Intensos processos de cisalhamento e brechação hidrotermal estão associados à mineralização de cobre. Cloritização e albitização, sobrepostos por processos hidrotermais tardios, representados por alteração potássica com feldspato potássico e formação de óxidos de ferro (hematita), estão relacionados aos processos mineralizantes. As zonas mineralizadas são representadas por veios e zonas com sulfetos disseminados. A paragênese de minério é constituída predominantemente por calcopirita, calcocita, pirita e bornita subordinada; com malaquita e rara azurita compondo os termos oxidados. Os controles estruturais associados a zonas de cisalhamentos, a intensa alteração hidrotermal e o estilo de mineralização permitem classifi car o Prospecto Aurora como semelhante aos depósitos da classe de óxido de ferro-cobre-ouro (iron oxide-copper-gold deposits ou IOCG) de idade brasiliana ou pós-brasiliana. Palavras-chave:Prospecto Aurora, hidrotermal, calcopirita, hematita, IOCG, Província Borborema. Abstract Geological characterization of the Aurora iron oxide-copper-gold (IOCG) prospect, Ceará,Brazil. The Aurora copper occurrence is situated in the northeastern region of Brazil (Ceará State), within the Borborema Province and the Meso-Neoproterozoic mobile belt of the Transversal Zone Domain, along the Patos Shear Zone. The host rocks are composed mainly of metavolcanosedimentary units of the Cachoeirinha Group. Intense shearing and brecciation are related to hydrothermal processes and copper mineralization at the Aurora Prospect. Choritization and albitization superposed by later K-feldspar and hematite hydrothermal alteration are related with copper mineralization. The ore zones consist of veins and disseminated sulfi des. The ore paragenesis comprises mainly chalcopyrite, chalcocite and pyrite. The structural control related to shear zone, the intense hydrothermal alteration and the style of mineralization indicate that the Aurora copper occurrence represents a Neoproterozoic to Paleozoic IOCG type of mineralization.

ResumoMaria, 35 anos, iniciou tratamento psicológico por indicação de seu médico psiquiatra e apresentava sintomas obsessivo-compulsivos [OCs] severos, com significativo prejuízo no seu funcionamento social, ocupacional e na sua saúde. Suas obsessões eram associadas à ideia de contaminação e doença, e suas compulsões eram de limpeza e higiene. Apresentava também comportamentos de esquiva associados às obsessões e reduzido repertório social. A história de vida e a avaliação psicológica de Maria permitiram compreender a evolução de seu quadro sintomatológico e a identificação dos aspectos predisponentes, precipitadores e mantenedores do transtorno obsessivo-compulsivo [TOC]. Baseado no registro realizado durante os atendimentos psicológicos, com o tratamento cognitivo-comportamental, observou-se uma redução na frequência dos comportamentos compulsivos. A auto avaliação da cliente e a observação clínica também apontaram uma melhora no funcionamento social e em sua condição física. No entanto, não foi possível realizar o follow-up para averiguar permanência dos ganhos obtidos durante o tratamento. Palavras-chave:Comportamento; Obsessivo; Terapia AbstRAct Maria, aged 35, began psychological treatment after referral by her psychiatrist, presenting severe obsessive-compulsive symptoms [OCs] which had a significantly adverse impact on her social and occupational function and on her health. Her obsessions were associated with the idea of infection and illness and her compulsions were cleanliness and hygiene. She also presented avoidance behaviors associated with these obsessions and deficit in social skills. Maria's life history and her psychological assessment enabled us to understand the development of her symptoms and to identify the predisposing, precipitating and maintaining aspects of the obsessive-compulsive disorder [OCD]. Based on the records kept during the cognitive-behavioral treatment, a reduction in the frequency of her compulsive behavior was observed. The client's self-assessment and the clinical observations also pointed towards improvement in social function and physical condition. Future efforts should include a follow-up to check for the maintenance of these gains. CASE CONTEXT AND METHOD The RaTionale foR SelecTing ThiS PaRTiculaR clienT STudyThere were four main reasons that determined the choice of Maria's case for this study: the OCD diagnosis, the severity of the OC symptoms, the lack of prior psychological treatment, and the cognitive-behavioral treatment carried out. This case illustrates the incapacitation caused by OC symptoms and the influence of life history on the development and permanence of the disorder. An analysis of the records kept during the psychological therapy session also allowed us to ascertain the progress made with the cognitive-behavioral treatment.

The present study aimed to investigate the perception of risk in the Brazilian population related to electric and magnetic fields. Six hundred adults were recruited from the surrounding communities. Three hundred of them lived in large cities and an equal number lived in small towns. A short questionnaire was constructed to assess risk perception, trust in government to control risk exposure, level of comfort with exposure to extra-low-frequency electromagnetic fields, measures perceived as necessary to reduce emotional discomfort, and trust in the regulatory agencies. The Lipp Inventory of Stress Symptoms for Adults was applied to assess stress levels. Findings indicate that the majority of the participants in this study did not trust the Government to provide protective measures from exposure to electric and magnetic fields, did not trust the regulatory agencies, felt that there is no adequate risk control and thought about it frequently, and some felt that line installations were being performed in excess and that this should be stopped. Results endorse the need for risk education and indicate that risk perception and feelings should be considered before starting new line installations. Risk communication should incorporate knowledge regarding social cognition since a large proportion of the people were concerned about electric and magnetic fields. Lack of communication can lead to a rejection of necessary transmission line installation, and to unnecessary or exaggerated fear.
