ABSTRACT
Resumen La evaluación subjetiva ha sido descripta como una variable mediadora para la respuesta emocional. Se presenta con diferentes contenidos y estilos. El estilo cognitivo se refiere a la manera en que se piensa sobre el estresor, por ejemplo: la rumiación (pensamientos intrusivos, repetitivos, que generan malestar emocional), la evitación (intentos por no pensar en el estresor) y el compromiso cognitivo (enfocados en búsqueda de sentido o solución). En base a esta respuesta emocional, se busca explorar y describir los pensamientos relacionados con el cáncer en un grupo de diez pacientes con la enfermedad. En un estudio cualitativo, se les pidió a diez pacientes con cáncer que indicaran los cinco pensamientos más frecuentes desde su diagnóstico. Se analizó el contenido mediante la técnica top down (teoría a contenido) y, a partir de los estilos de respuestas cognitivas, se clasificó el contenido de los pensamientos reportados por estilo de pensamiento (rumiación, compromiso cognitivo o evitación), por temporalidad (pasado, presente y futuro) y por valencia (positiva o negativa). Posteriormente, se hizo el análisis bottom up (contenido a teoría). Se hicieron tablas cruzadas para identificar los contenidos según el estilo de pensamiento, la temporalidad y la valencia. En los pensamientos con estilo rumiativo, el enfoque temporal se dirigía en su mayoría al futuro y al pasado, mientras que el compromiso cognitivo se enfocaba en el presente. Esta diferencia fue estadísticamente significativa mediante una prueba de chi cuadrado. Dentro de los temas relacionados con la incertidumbre, se refirieron a la muerte, al pronóstico de la enfermedad, a la respuesta de la familia y a las finanzas (en el futuro) y a las causas y culpa (en el pasado).
Abstract Cancer has been defined by the World Health Organization as "a disease caused by abnormal cells growing uncontrollably in the body, going beyond their usual boundaries, invading adjoining parts of the body and spreading to other organs". Being diagnosed with cancer has been described as an experience with diverse emotional reactions and difficulties in adaptation, having psychological consequences, being most common depression, anxiety and psychological distress; but also, some patients present positive consequences after having a cancer diagnosis, such as post traumatic growth, which includes positive changes presented after the disease experience. Subjective appraisal about cancer has been defined as a mediating variable for the emotional response presented after a stressor, such as cancer diagnosis, treatment, or important changes during disease process (initiating and finalizing treatment, presenting relapse or remission, as well as when having control studies). The subjective appraisal can be presented with different thought content and styles. Thought style is referred as the way thoughts about the stressor are presented, it has been classified as rumination (thoughts that are intrusive and repetitive that also increase psychological distress), cognitive engagement (thoughts associated with problem solving and meaning finding) or avoidance (aiming to stop thinking about stressor or feeling associated with it). Depending on the thought style presented at a stressor, could be the emotional response (anxiety, depression, distress, post-traumatic growth). The aim of the present study was to describe the thoughts (style, content, valence and temporality) related to cancer diagnosis in a group of ten oncologic patients. To identify if differences between thought style, valence and temporality were presented. The study design is qualitative from a phenomenological point of view. Ten oncologic (different cancer type, clinical stage and treatment) patients were asked to write the five more frequent thoughts since their cancer diagnosis. Each thought was classified by: thought style, valence, and temporality (top-down, classifying the thoughts according to theory). The same thoughts were also classified in semantic units (bottom-up, classifying the thoughts according to their own contents), generating concerns from the content. Cross tabs were made to identify contents and temporality for thought style and valence, which were analyzed by chi square to identify differences between thought style, temporality and valence. The most common thought style was cognitive engagement, followed by rumination (almost same frequency). On what respects to thought style and temporality, rumination was more focused on past (causes and attributions of cancer) and future (uncertainty about death and treatment effectiveness); meanwhile, cognitive engagement was focused on present (to enjoy present moment and focus on daily actions). Chi square was made to identify if this difference was significant, showing temporality was significantly different in cognitive engagement and rumination. The concerns identified in study participants were uncertainty about future and disease, family (communication and wellness of the family), finances (due to expensive treatments), causes and guilt about having cancer. Thoughts that were more centered in present, were more likely to be associated with cognitive engagement. Cognitive engagement has been described previously as an important variable associated with post traumatic growth. Thoughts centered in the past and present were more associated with rumination. Rumination has been associated with depression and post-traumatic stress disorder. Because of mediating role of thought style in disease adaptation, emotional response to the disease, and the relation of this adaptation with the perception of quality of life in cancer patients, the design of psychological interventions aiming on promoting cognitive engagement by problem solving skills, meaning finding, and focusing on present could be a research line derived from present studies results.
ABSTRACT
Resumo Em 1958, Eiseman e colaboradores publicaram o primeiro artigo científico relatando o uso de transplante de microbiota fecal para tratar casos graves de colite pseudomembranosa. A relevância desse trabalho inovador só foi reconhecida em 1990. A literatura acadêmica sobre o tema caracteriza-se por sucessivas reconstruções. Sugerimos que tais reconstruções foram orientadas por questões de atribuição de prioridade de descoberta científica nos termos propostos por Merton. A retomada do uso de transplantes de microbiota fecal é interpretada como processo de gênese de um fato científico, conforme Fleck: ocorre a mudança de um estilo de pensamento baseado no uso de antibióticos no tratamento de doenças infecciosas para outro que considera as relações ecológicas entre hospedeiros, vetores e agentes etiológicos de doenças.
Abstract In 1958, Eiseman and contributors published the first scientific paper reporting the use of fecal microbiota transplant for treating pseudomembranous colitis. The relevance of this innovative paper was only acknowledged in 1990. The academic literature on the theme is characterized by a narrative that has undergone successive revisions. We suggest that such revisions were based on claims of priority of scientific discoveries, as described by Merton. The revival of fecal microbiota transplants is interpreted as a process of genesis of a scientific fact, as defined by Fleck: there is a switch from a thought style based on the use of antibiotics to treat infectious diseases to another that accepts the ecological relations between hosts, vectors and parasites.

Este artigo trata da construção do estilo de pensamento odontológico baseado na etiologia da cárie. Tem como referencial a epistemologia de Ludwick Fleck (1896-1961),na qual o conhecimento é o resultado da atividade social e cada conhecedor pertence a um coletivo e um estilo de pensamento. O estudo das transformações na teoria foi desenvolvido através de livros clássicos e artigos coletados no Medline/Pubmed, com as palavras-chave: dental caries/etiology/theoretical, de 1980 a 2001, um universo de 161 artigos selecionados. Na construção histórica do conhecimento etiológico, apontou-se um macro-estilo de pensamento caracterizado como multicausal-biologicista. Foram identificadas cinco tendências à transformação do estilo: a biologicista, que segue o modelo proposto por Keyes; a clínico-epidemiológica, que incorpora algumas características da visão epidemiológica juntamente com a ciência clínica tradicional; a clínico-biologicista, localizada nas figuras de Thylstrup e Fejerskov, considera as evidências epidemiológicas, mas parte de uma visão clínica da boca em direção ao meio externo; a biopsicossocial, que acolhe num mesmo patamar os fatores biológicos, psicológicos e sociais; e a social, que propõe formas de abordagem da doença partindo-se do geral para o específico.
This study deals with the construction of the Odontological Thought Style about the etiology of caries. As a reference we use the theory of Ludwik Fleck (1896 -1961) maintaining that knowledge is a result of social activity and that each individual with certain knowledge belongs to a certain cultural environment, a thought-collective sharing the same thought-style. The sources used for studying the transformations in the theory were classic literature and a universe of 161 articles published between 1980 and 2001, selected from the Medline/Pubmed base using the key words dental caries/etiology/theoretical. Based on the analysis of these articles and books we identified a macro style of thinking characterized as multicausal-biologicist transforming the etiological knowledge mainly since the mid 90s. In this stage, in which the period of classicism of the theory does not respond any more to the reality of the disease revealed in epidemiological studies, five distinct trends could be identified: the biological; the clinical-biological; the clinical-epidemiological; the biopsychosocial and the social. Thus, one of the challenges posed to odontology today is to transform its thought-style adapting it to the new social reality of the disease.
