Abstract: Introduction: Hospital Recreation (HR) aims to reduce disasters caused by hospital admission. Objectives: To expose the behavior of children in cancer treatment (CA) during HR, and to verify which recreational activities generate the most adherence. Methods: The research is an experimental clinical trial of a non-probabilistic and intentional sample, with a quantitative and qualitative approach. Participants were 43 children (both sexes), with CA, admitted to the Pediatric Hospital Oncology CenterPHOC. The mean age of the children in fact was 7.5 years, and the data of mean and standard deviation between parenthood confer with the data of the results found during the research. The study lasted 12 weeks, with 38 sessions lasting 3 hours. Using games of activity: cognitive, manipulative, perceptive, creative and cooperative. Inclusion criteria: 1) being hospitalized in the PHOC, of the city of Natal; 2) being released by the medical team to participate in the activities. Children who were on special care in the ICU were excluded from the study. The behavior of the children was evaluated by the observation matrix proposed by Urie Bonfenbrenner, approached by Krebs and Koller. At

Abstract: the relationship between lipid peroxidation, antioxidant defense and diabetic osteopenia remains unclear. this study evaluated the relationship among lipid peroxidation index, antioxidant defense parameters and bone metabolism in a premenopausal diabetic model using measures including thiobarbituric acid-reactive substances concentration (tbars) and reduced glutathione (gsh) content in brain homogenates, histomorphometric analysis, biomechanical testing and bone mineral density (bmd). female wistar rats with regular estrous cycle were divided into two groups: group 1: control rats (n = 15) and group 2: diabetic rats (n = 15). diabetes was induced by alloxan and confirmed by glycemia >250 mg/dl. the lipid peroxidation index, measured by tbars concentration, showed a significant increase (p<0.05) in diabetic animals in comparison to control animals. however, the antioxidant parameter measured by gsh content, was significantly lower (p<0.05) in diabetic animals. histomorphometric analysis showed a significant increase (p<0.05) in femoral trabecular separation together with a significant decrease (p<0.05) in trabecular thickness, and reduced trabecular bone volume in diabetic rats. moreover, biomechanical testing and bmd values were significantly lower (p<0.05) in the diabetic group. thus, our results demonstrated that increased lipid peroxidation and altered antioxidant defense could be related to the development of oxidative stress and diabetic osteopenia in premenopausal rats.

Abstract: objectives: to revise theories and the available evidence about cognitive behavioral therapy (cbt) role on the relapse and recurrence prevention of depressive episodes. methods: review of random and controlled clinical trials that investigated cbt efficacy on the relapse and recurrence prevention of depressive episodes. the following databases were used: medline, lilacs, cochrane, biosis and embase. the reference sections of the selected articles, review articles and specialized books were consulted. results: fifteen studies with different experimental design were found, several with methodological problems. the majority of them compared cbt with antidepressants at the acute treatment phase. in 12 studies cbt significantly lowered the relapse/recurrence rate. recent papers pointed to the cbt usefulness for treating residual depressive symptoms as a recurrence prevention strategy. conclusion: cbt was effective for the depression relapse reduction. its relationship with antidepressants as a prevention tool and cbt strategies (using it only in the acute phase, or during acute and maintenance phases, or after antidepressants withdrawal as a maintenance treatment, or focusing residual symptoms) need to be better investigated.

Abstract: experiences regarded as mediumistic have been found in most civilizations and have exerted an important influence over the societies. despite few academic studies nowadays, mediumship was a subject of serious investigations by some psychiatry and psychology pioneers. research developed by janet, james, myers, freud and jung concerning mediumship was revised, two points were stressed: its causes and its relations with psychopathology. these researchers had come to three distinct conclusions. janet and freud associated mediumship with psychopathology and an exclusive origin in the personal unconscious; jung and james accepted the possibility of a non-pathological aspect of mediumship and an origin in the personal unconscious, but without definitively excluding the actuation of a discarnate spirit. finally, myers saw mediumship as a higher development of the personality, having as its causes a combination of the unconscious, telepathy and the action of discarnate spirits. the authors argue the need to become acquainted with the studies already done in order to resume these investigations in search of a really scientific paradigm about mediumship.

Abstract: anomalous experiences (ae) (uncommon experiences or one that is believed to deviate from the usually accepted explanations of reality: hallucinations, synesthesia, experiences interpreted as telepathic...) and altered states of consciousness (asc) are described in all societies of all ages. even so, the scientists have long neglected the studies on this theme. to study ae and asc is not necessary to share the believes we discuss, they can be investigated as subjective experiences and correlated like any other set of data. this article presents some methodological guidelines to explore these experiences, among them: to avoid prejudice approaches and to "pathologize" the unusual, the value of a theory and a comprehensive review of literature, using various concepts of pathology and normality, the investigation of clinical and non-clinical populations, development of new search instruments, to be careful to choose terms and to decide causal nexus, to distinguish experiences and interpretations, to take into account the role of culture, to evaluate the validity and reliability of reports, and the last, but not least, creativity and diversity in choosing methods.

Abstract: OBJETIVO: Fazer um levantamento das teorias e revisar as evidências existentes sobre o papel da terapia cognitiva-comportamental (TCC) na preven o de recaídas e recorrências de episódios depressivos. MéTODO: Revis o dos ensaios clínicos randomizados e controlados que investigam a eficácia da TCC na preven o de recaídas e/ou recorrências depressivas. As bases de dados consultadas foram o Medline, Lilacs, Cochrane, Biosis e a Embase. Foram verificadas as referências bibliográficas dos artigos selecionados, de artigos de revis o e de livros sobre o tema. RESULTADOS: Foram encontrados 15 estudos de desenhos heterogêneos e vários deles com problemas metodológicos. A maioria comparou o uso de TCC e antidepressivos apenas na fase aguda. Em 12 deles a TCC diminuiu a taxa de recorrência/recaídas de modo estatisticamente significativo. As publica es mais recentes apontam para a utilidade da TCC nos sintomas depressivos residuais como estratégia preventiva de recorrências. CONCLUS ES: A TCC mostrou-se eficaz na redu o de recaídas depressivas, mas ainda precisam ser mais bem investigadas sua eficácia em rela o ao uso de antidepressivos e qual estratégia de TCC (seu uso apenas na fase aguda, na fase aguda e manuten o, na manuten o após antidepressivo na fase aguda ou o enfoque nos sintomas residuais após antidepressivo na fase aguda) é mais eficaz para cada tipo de paciente.

Abstract: the objective of this work was to determine the productive potential and the genotype by environment interaction of 550 accessions of the embrapa's rice core collection. the performance, and yield adaptability and stability of each genotype was evaluated using the additive main effects and multiplicative interactions (ammi) approach, in nine field experiments, carried out in six brazilian states, under dry and irrigated conditions, during three years. the linear mixed model analysis was performed, and the estimates of the variance components were obtained by the residual maximum likelihood (reml), using the best linear unbiased prediction (blup) procedure for the prediction of the genotypic values of random effects (eblup) associated with each accession. the group of accessions with better performance was the one of lines and cultivars from brazil (lcb), as expected. however, traditional varieties (vt) were identified among the best yielding genotypes, which shows the potential of this germplasm group to contribute as a new source of genetic variability to breeding programs. superior accessions were identified for their stability, adaptability and grain yield, among which ca880078, ca840182 and cna00091 stand out.
