Cenário das pesquisas na pós-graduação na área de enfermagem e gerenciamento no Brasil

Trata-se de um estudo documental, descritivo, com abordagem quantitativa, com o objetivo de caracterizar a produção da pós-graduação brasileira na área da enfermagem no triênio 2007-2009, com ênfase na temática gerenciamento em enfermagem. As informações foram obtidas no banco de dados da CAPES, que disponibiliza resumos de dissertações e teses. O material foi analisado e categorizado segundo as áreas/campos e respectivas linhas de pesquisa, definidas pela área de Enfermagem. A análise da produção em geral foi descritiva e analítica/crítica no campo organizacional, especificamente, na temática do gerenciamento. Os resultados mostraram algumas mudanças na produção no triênio, quando comparada aos estudos anteriores, destacando-se o crescimento da área/campo assistencial, manutenção da organizacional e queda na área/campo profissional. Na temática de gerenciamento houve o predomínio de estudos sobre avaliação em saúde, concepções/percepções sobre planejamento/organização, do trabalho-serviços e educação permanente

Immunotherapy with MVA-BN®-HER2 induces HER-2-specific Th1 immunity and alters the intratumoral balance of effector and regulatory T cells

MVA-BN®-HER2 is a new candidate immunotherapy designed for the treatment of HER-2-positive breast cancer. Here, we demonstrate that a single treatment with MVA-BN®-HER2 exerts potent anti-tumor efficacy in a murine model of experimental pulmonary metastasis. This anti-tumor efficacy occurred despite a strong tumor-mediated immunosuppressive environment characterized by a high frequency of regulatory T cells (Treg) in the lungs of tumor-bearing mice. Immunogenicity studies showed that treatment with MVA-BN®-HER2 induced strongly Th1-dominated HER-2-specific antibody and T-cell responses. MVA-BN®-HER2-induced anti-tumor activity was characterized by an increased infiltration of lungs with highly activated, HER-2-specific, CD8+CD11c+ T cells accompanied by a decrease in the frequency of Treg cells in the lung, resulting in a significantly increased ratio of effector T cells to Treg cells. In contrast, administration of HER2 protein formulated in Complete Freund’s Adjuvant (CFA) induced a strongly Th2-biased immune response to HER-2. However, this did not lead to significant infiltration of the tumor-bearing lungs by CD8+ T cells or the decrease in the frequency of Treg cells nor did it result in anti-tumor efficacy. In vivo depletion of CD8+ cells confirmed that CD8 T cells were required for the anti-tumor activity of MVA-BN®-HER2. Furthermore, depletion of CD4+ or CD25+ cells demonstrated that tumor-induced Treg cells promoted tumor growth and that CD4 effector cells also contribute to MVA-BN®-HER2-mediated anti-tumor efficacy. Taken together, our data demonstrate that treatment with MVA-BN®-HER2 controls tumor growth through mechanisms including the induction of Th1-biased HER-2-specific immune responses and the control of tumor-mediated immunosuppression

Influência do estado nutricional no risco para transtornos alimentares em estudantes de nutrição

Avaliar a relação entre a alteração do comportamento alimentar, associado à insatisfação com a imagem corporal, e o estado nutricional de universitárias de Nutrição. Realizou-se um estudo transversal com 175 universitárias do Curso de Nutrição (ENUT/UFOP). Foram aplicados os questionários Eating Attitudes Test-26 (EAT-26) e o Body Shape Questionare (BSQ) e realizadas medidas antropométricas. 21,7% das estudantes apresentaram alto risco para transtornos alimentares e 13,7% apresentaram insatisfação com a imagem corporal. A maioria das estudantes com BSQ e EAT-26 positivos estava eutrófica. As estudantes com excesso de peso, aumento do percentual de gordura corporal (% GC) e do perímetro da cintura (PC) apresentaram risco 5 a 9 vezes maiores de alteração do comportamento alimentar. Houve associação positiva entre os parâmetros antropométricos com a pontuação dos questionários EAT-26 e BSQ. Futuras nutricionistas com excesso de peso apresentaram maior risco de estarem insatisfeitas com a sua imagem corporal e de desenvolverem transtornos alimentares. A utilização de outros parâmetros antropométricos, além do IMC, pode ser útil na triagem de indivíduos suscetíveis ao surgimento de preocupações excessivas com o peso corporal e a alimentação.The scope of this paper was to evaluate the relationship between changes in eating behavior associated with dissatisfaction with body image, and the nutritional status of female university students of nutrition. A cross-sectional study was conducted among 175 female students of nutrition (ENUT/UFOP). The Eating Attitudes Test-26 (EAT-26) and Body Shape Questionnaire (BSQ) were applied and anthropometric measurements were taken. 21.7% of the students were found to be high risk in terms of eating disorders, and 13.7% declared dissatisfaction with their body image. The majority of students with positive results in the BSQ and EAT-26 tests were eutrophic. The students who were overweight, with elevated body fat percentage (% BF) and waist circumference (WC) had a 5-9 times greater risk of change in eating habits. There was a positive association between the anthropometric parameters with high scores in the EAT-26 and BSQ questionnaires. The future dietitians who are overweight, with increased body fat and waist circumference were more likely to be dissatisfied with their body image and develop eating disorders. The use of other anthropometric parameters, in addition to BMI, may prove useful in screening individuals susceptible to the emergence of excessive concerns with weight and diet

Use of patients’ classification instruments: analysis of the brazilian production of knowledge

Objective To analyze the production of scientific knowledge about the use of patients’ classification instruments in care and management practice in Brazil. Method Integrative literature review with databases search in: Latin American and Caribbean Literature on Health Sciences (LILACS), Medical Literature Analysis and Retrieval System on-line (MEDLINE), Cumulative Index to Nursing and Allied Health Literature (CINAHL) and SCOPUS, between January 2002 through December 2013. Results 1,194 studies were found, 31 met the inclusion criteria. We observed a higher number of studies in the category care plans and workload (n=15), followed by the category evaluation of psychometric properties (n=14). Conclusion Brazilian knowledge production has not yet investigated some purposes of using instruments for classifying patients in professional nursing practice. The identification of unexplored areas can guide future research on the topic
