Cultural adaptation of the scale Pain Assessment in Advanced Dementia – PAINAD to Brazil

Objective: To translate and culturally adapt to Brazil the scale Pain Assessment in Advanced Dementia(PAINAD).Method: The cultural adaptation process followed the methodology of a theorical reference, in five steps: translation to Brazilian Portuguese, consensual version of translations, back-translation to the original language, revision by a committee of specialists in the field and a equivalency pre-test. The instrument was assessed and applied by 27 health professionals in the last step. Results: The Escala de Avaliação de Dor em Demência Avançada was culturally adapted to Brazil and presented semantic equivalency to the original, besides clarity, applicability and easy comprehension of the instrument items. Conclusion: This process secured the psychometric properties as the reliability and content validity of the referred scale.


On the number of independent cultural traits carried by individuals and populations.

In species subject to individual and social learning, each individual is likely to express a certain number of different cultural traits acquired during its lifetime. If the process of trait innovation and transmission reaches a steady state in the population, the number of different cultural traits carried by an individual converges to some stationary distribution. We call this the trait-number distribution. In this paper, we derive the trait-number distributions for both individuals and populations when cultural traits are independent of each other. Our results suggest that as the number of cultural traits becomes large, the trait-number distributions approach Poisson distributions so that their means characterize cultural diversity in the population. We then analyse how the mean trait number varies at both the individual and population levels as a function of various demographic features, such as population size and subdivision, and social learning rules, such as conformism and anti-conformism. Diversity at the individual and population levels, as well as at the level of cultural homogeneity within groups, depends critically on the details of population demography and the individual and social learning rules.

Improved immunogenicity against HIV-1 clade C antigens by using NYVAC-C with restored replication competence.

In order to improve the immunogenicity of currently available non-replicating pox virus HIV vaccine vectors, NYVAC was genetically modified through re-insertion of two host range genes (K1L and C7L), resulting in restored replicative capacity in human cells. In the present study these vectors, expressing either a combination of the HIV-1 clade C antigens Env, Gag, Pol, Nef, or a combination of Gal, Pol, Nef were evaluated for safety and immunogenicity in rhesus macaques, which were immunized at weeks 0, 4 and 12 either by scarification (conventional poxvirus route of immunization), intradermal or by intramuscular injection (route used in previous vaccine studies).Replication competent NYVAC-C-KC vectors induced higher HIV-specific responses, as measured by IFN- ELISpot assay, than the replication defective NYVAC-C vectors. Application through scarification only required one immunization to induce maximum HIV-specific immune responses. This method simultaneously induced relatively lower anti-vector responses. In contrast, two to three immunizations were required when the NYVAC-C-KC vectors were given by intradermal or intramuscular injection and this method tended to generate slightly lower responses. Responses were predominantly directed against Env in the animals that received NYVAC-C-KC vectors expressing HIV-1 Env, Gag, Pol, Nef, while Gag responses were dominant in the NYVAC-C-KC HIV-1 Gag, Pol, Nef immunized animals.The current study demonstrates that NYVAC replication competent vectors were well tolerated and showed increased immunogenicity as compared to replication defective vectors. Further studies are needed to evaluate the most efficient route of immunization and to explore the use of these replication competent NYVAC vectors in prime/boost combination with gp120 protein-based vaccine candidates. This studies was performed within the Poxvirus T-cell Vaccine Discovery Consortium (PTVDC) which is part of the CAVD program.

Prevalence of obesity and overweight and associated nutritional factors in a population-based Swiss sample: an opportunity to analyze the impact of three different European cultural roots.

PURPOSE: Obesity represents a growing public health concern worldwide. The latest data in Switzerland rely on self-reported body mass index (BMI), leading to underestimation of prevalence. We reassessed the prevalence of obesity and overweight in a sample of the Swiss population using measured BMI and waist circumference (WC) and explored the association with nutritional factors and living in different linguistic-cultural regions. METHODS: Data of 1,505 participants of a cross-sectional population-based survey in the three linguistic regions of Switzerland were analyzed. BMI and WC were measured, and a 24-h urine collection was performed to evaluate dietary sodium, potassium and protein intake. RESULTS: The prevalence of overweight, obesity and abdominal obesity was 32.2, 14.2 and 33.6 %, respectively. Significant differences were observed in the regional distribution, with a lower prevalence in the Italian-speaking population. Low educational level, current smoking, scarce physical activity and being migrant were associated with an higher prevalence of obesity. Sodium, potassium and protein intake increased significantly across BMI categories. CONCLUSIONS: Obesity and overweight affect almost half of the Swiss adolescents and adults, and the prevalence appears to increase. Using BMI and WC to define obesity led to different prevalences. Differences were furthermore observed across Swiss linguistic-cultural regions, despite a common socio-economic and governmental framework. We found a positive association between obesity and salt intake, with a potential deleterious synergistic effect on cardiovascular risk.

Pensar currículo como um enunciado cultural com foco na Língua Crioula Cabo-Verdiana

Neste estudo, dedicamo-nos à análise da política curricular cabo-verdiana, enfatizando a constituição da língua crioula como enunciação cultural. Temos como objetivo desconstruir o conceito de tradição cultural, dando maior enfoque a tradução cultural, na tentativa de explicar o conceito construído pela identidade cabo-verdiana. A nosso ver, a compreensão desses conceitos numa perspectiva pós-moderna e pós-colonial nos possibilita pensar o currículo como um enunciado cultural. Nesse sentido, a cultura assume um papel de base e de centralidade no currículo, trazendo à tona questões para negociação e articulação das culturas que compõem Cabo Verde. O estudo tem como base teórica pesquisadores cabo-verdianos, para discutir as questões no campo de história e cultura; os estudos de Stephen Ball para o ciclo de política; de Ernesto Laclau e Chantal Mouffe para a definição do político/da política; de Stuart Hall e Homi Bhabha para as questões da diferença e cultura e; Elizabeth Macedo e Alice Lopes para o campo do currículo. Para a elaboração do trabalho foram utilizados os seguintes recursos metodológicos: pesquisa bibliográfica; análise documental; estudos de obras ligadas à historiografia política e intelectual cabo-verdiana e africana. Concluímos que o processo de oficialização da língua cabo-verdiana está, profundamente, condicionado pelas representações acerca das línguas que os falantes têm e que em Cabo Verde, correspondem a formações linguísticas muito específicas.

A política de formação de quadros e o capital cultural dos altos funcionários públicos cabo-verdianos

A estratégia de desenvolvimento de Cabo Verde tem passado por um acentuado investimento na formação dos seus recursos humanos, desde a expansão e democratização do ensino básico até à recente criação da Universidade estatal. A aposta numa política de formação de quadros teve de contar com a cooperação com outros países, dada a inexistência de ensino superior nas ilhas e à incapacidade financeira para a sua implementação. Nesta apresentação, pretende-se demonstrar que uma das consequências do investimento na educação foi a constituição de uma elite cujo traço comum é a sua formação académica adquirida fora das ilhas e a capacidade técnica desenvolvida na chefia dos serviços públicos. Desse capital cultural faz parte toda a experiência que conseguiram amealhar no estrangeiro durante o seu período de estudos universitários, debatendo-se com obstáculos linguísticos, culturais, financeiros e, até, identitários, os quais representam uma riqueza adicional ao seu perfil enquanto dirigentes da administração pública cabo-verdiana.

Vaccination-induced functional competence of circulating human tumor-specific CD8 T-cells.

T-cells specific for foreign (e.g., viral) antigens can give rise to strong protective immune responses, whereas self/tumor antigen-specific T-cells are thought to be less powerful. However, synthetic T-cell vaccines composed of Melan-A/MART-1 peptide, CpG and IFA can induce high frequencies of tumor-specific CD8 T-cells in PBMC of melanoma patients. Here we analyzed the functionality of these T-cells directly ex vivo, by multiparameter flow cytometry. The production of multiple cytokines (IFNγ, TNFα, IL-2) and upregulation of LAMP-1 (CD107a) by tumor (Melan-A/MART-1) specific T-cells was comparable to virus (EBV-BMLF1) specific CD8 T-cells. Furthermore, phosphorylation of STAT1, STAT5 and ERK1/2, and expression of CD3 zeta chain were similar in tumor- and virus-specific T-cells, demonstrating functional signaling pathways. Interestingly, high frequencies of functionally competent T-cells were induced irrespective of patient's age or gender. Finally, CD8 T-cell function correlated with disease-free survival. However, this result is preliminary since the study was a Phase I clinical trial. We conclude that human tumor-specific CD8 T-cells can reach functional competence in vivo, encouraging further development and Phase III trials assessing the clinical efficacy of robust vaccination strategies.

Gluco-incretins regulate beta-cell glucose competence by epigenetic silencing of Fxyd3 expression.

BACKGROUND/AIMS: Gluco-incretin hormones increase the glucose competence of pancreatic beta-cells by incompletely characterized mechanisms. METHODS: We searched for genes that were differentially expressed in islets from control and Glp1r-/-; Gipr-/- (dKO) mice, which show reduced glucose competence. Overexpression and knockdown studies; insulin secretion analysis; analysis of gene expression in islets from control and diabetic mice and humans as well as gene methylation and transcriptional analysis were performed. RESULTS: Fxyd3 was the most up-regulated gene in glucose incompetent islets from dKO mice. When overexpressed in beta-cells Fxyd3 reduced glucose-induced insulin secretion by acting downstream of plasma membrane depolarization and Ca++ influx. Fxyd3 expression was not acutely regulated by cAMP raising agents in either control or dKO adult islets. Instead, expression of Fxyd3 was controlled by methylation of CpGs present in its proximal promoter region. Increased promoter methylation reduced Fxyd3 transcription as assessed by lower abundance of H3K4me3 at the transcriptional start site and in transcription reporter assays. This epigenetic imprinting was initiated perinatally and fully established in adult islets. Glucose incompetent islets from diabetic mice and humans showed increased expression of Fxyd3 and reduced promoter methylation. CONCLUSIONS/INTERPRETATION: Because gluco-incretin secretion depends on feeding the epigenetic regulation of Fxyd3 expression may link nutrition in early life to establishment of adult beta-cell glucose competence; this epigenetic control is, however, lost in diabetes possibly as a result of gluco-incretin resistance and/or de-differentiation of beta-cells that are associated with the development of type 2 diabetes.

Evaluation of professional knowledge and attitudes on dementia patient care: a trans-cultural adaptation of an evaluation instrument

Objective To describe the trans-cultural adaptation of the evaluation instrument entitled Atenció Sanitària de Les Demències: la visió de L' Atenció Primarià from Catalan into versions in Portuguese for doctors and nurses. This study evaluates the knowledge and perspectives of these professionals in their treatment of patients diagnosed with dementia in cases of primary care. Method The adaptation followed internationally accepted rules, which include the following steps: translation, synthesis, back-translation, revision by a committee of specialists, and a test run with 35 practicing doctors and 35 practicing nurses in Brazil's Family Health Strategy (Estratégia Saúde da Família, or ESF in Portuguese). Results The translation, synthesis, and back-translation steps were performed satisfactorily; only small adjustments were required. The committee of specialists verified the face validity in the version translated into Portuguese, and all of the items that received an agreement score lower than 80% during the initial evaluation were revised. In the test run, the difficulties presented by the health care professionals did not reach 15% of the sample, and therefore, no changes were made. Conclusion The Portuguese translation of the instrument can be considered semantically, idiomatically, culturally, and conceptually equivalent to the original Catalan version and is, therefore, appropriate for use in Brazil.

A Condição de Mediador Político-Cultural em Cabo Verde: Intelectuais e Diferentes Versões da Identidade Nacional

Este artigo examina dois processos correlacionados à constituição de elites intelectuais em Cabo Verde: a disputa das várias versões sobre a identidade cultural das ilhas e a problemática da mediação política e cultural, isto é, de como diferentes lógicas (políticas, literárias) se articulam na relação entre a posição de produtor cultural e a condição de mediação cultural e política. Em Cabo Verde essa condição de mediador político-cultural tem sido disputada, ao longo deste século, por grupos que se definem como intelectuais. Além de demonstrar o caráter arbitrário da invenção de “essências” nacionais como a “cabo-verdianidade”, pretende-se aqui estabelecer correlações entre as lutas de legitimação das diversas versões de identidade nacional e a constituição de um espaço de mediação que proporciona importantes lucros materiais e simbólicos a quem o monopoliza.

Cross-cultural adaptation of the Quality of Life Index Spinal Cord Injury - Version III

OBJECTIVE To translate and culturally adapt to Portuguese the Ferrans and Powers Quality of Life Index Spinal Cord Injury - Version III and characterize the sample in relation to sociodemographic and clinical aspects. METHOD A methodological study with view to cross-cultural adaptation, following the particular steps of this method: initial translation, translation synthesis, back-translation (translation back to the original language), review by a committee of judges and pretest of the final version. The pretest was carried out with 30 patients with spinal cord injury. RESULTS An index of 74 items divided into two parts (satisfaction/importance) was obtained. The criteria of semantic equivalence were evaluated as very adequate translation, higher than 87%, and vocabulary and were grammar higher than 86%. Idiomatic equivalence was higher than 74%, experimental greater than 78% and conceptual was greater than 70%. CONCLUSION After cross-cultural adaptation, the instrument proved semantic, idiomatic, experimental and conceptual adequacy, in addition to helping the evaluation of the quality of life of people with spinal cord injury.

Cross-cultural adaptation of the Caregiver Reaction Assessment for use in Brazil with informal caregivers of the elderly

This study aimed to carry out the cross-cultural adaptation of the Caregiver Reaction Assessment CRA for use in Brazil with informal caregivers of dependent elderly METHOD A methodological study, of five steps: initial translation, synthesis of translations, retro-translation, evaluation by a judge committee and a pre-test, with 30 informal caregivers of older persons in Fortaleza, Brazil. Content validity was assessed by five experts in gerontology and geriatrics. The cross-cultural adaptation was rigorously conducted, allowing for inferring credibility. RESULTS The Brazilian version of the CRA had a simple and fast application (ten minutes), easily understood by the target audience. It is semantically, idiomatically, experimentally and conceptually equivalent to the original version, with valid content to assess the burden of informal caregivers for the elderly (Content Validity Index = 0.883). CONCLUSION It is necessary that other psychometric properties of validity and reliability are tested before using in care practice and research.
