Construção de portfólios coletivos em currículos tradicionais: uma proposta inovadora de ensino-aprendizagemThe construction of collective portfolios in traditional curriculums: an innovative approach in teaching-learning Resumo Tradicionalmente, a educação em saú-de se baseia em metodologias de transmissão de conhecimentos. Porém, agora se exige a formação de profissionais com perfil crítico-reflexivo e capazes de trabalhar em equipes. O que requer novas metodologias de ensino-aprendizagem, tendo na problematização um instrumento de transformação. É relatada experiência utilizando a construção de portfólios coletivos na aprendizagem, como mudança de atitudes e na avaliação de alunos de graduação, em contexto de estrutura curricular tradicional e por disciplinas. Estudo exploratório descritivo, com abordagem quali-quantitativa, fundamentado na análise de portfólios coletivos (n= 9), construídos pelos acadêmicos da disciplina Políticas de Saúde, complementado com a aplicação de um questionário aberto aos alunos (n=58) e com a realização de grupos focais (n=3). Os portfólios coletivos mobilizaram o pensamento crítico-reflexivo sobre a política do Sistema Único de Saúde, ampliando a concepção sobre o processo saúde-doença e as práticas relacionadas aos serviços de saúde, valorizando o trabalho em equipe e a busca ativa na construção do conhecimento, destacando-se os exercícios da alteridade, resiliência e empoderamento. Palavras-chave Portfólio, Metodologias de ensino-aprendizagem, Problematização, Educação em saúde, Formação profissional, Avaliação Abstract Education to promote health has traditionally been based on knowledge transmission methodologies. However, the current scenario calls for the training of professionals with a criticalreflective profile, who are able to work in teams. We present the report of an innovative experience using the construction of collective portfolios as instruments of learning, changing attitudes and training of undergraduates, in a traditional subject-based curriculum structure context. It is a descriptive exploratory study, with a qualitativequantitative approach, based on analysis of collective portfolios (n=9), built by Health Policy students, together with an open questionnaire to students who attended the course (n=58) and also the staging of focus groups (n=3). The use of collective portfolios mobilized students in critical and reflective thinking on Brazilian health policythe Unified Health System -broadening the concept on the health-disease process and practices related to health services, prioritizing teamwork and the active search for knowledge building, stressing the exercise of otherness, resilience and empowerment.

There is a growing mortality related to co-morbidities associated with diabetes mellitus. Intake of polyunsaturated fatty acids (PUFA) has been associated with low cardiometabolic risk and reduction of inflammatory process. The objective of this paper is to review the impact of PUFA intake on glycemic control in diabetic patients as well as to elucidate the possible mechanisms involved. Medline/PubMed electronic database was searched to identify studies published within last five years regarding the effect of PUFA intake on glucose metabolism in type 2 diabetics. The search terms used were "polyunsaturated fatty acid(s)," "PUFA," and "diabetes." We included only interventional studies that assessed the effects of PUFA intake on glucose metabolism - fasting glucose, serum insulin, HbA1c, and HOMA-IR assessment- in type 2 diabetics. Initially, 48 articles were identified, of which one was not available and 41 did not match the inclusion criteria. Within the selected studies, three articles showed an improvement in fasting blood glucose, two showed an increase in fasting glycemia, and there was no effect of intervention in one article only. Based on the analyzed clinical interventional studies, supplementation of 0.42-5.2-g PUFA/day for at least eight weeks may become an alternative treatment for type 2 diabetes mellitus, particularly in Asian subjects.

Este é um estudo qualitativo que se refere à relação da rede social e a amamentação. Como fundamentação teórica, utilizou-se a Teoria da Rede Social de Sanicola, bem como a Teoria das Representações Sociais descrita por Moscovici e Minayo. Participaram do estudo mães, pais e avós, de crianças até dois anos, residentes no município de Coimbra-MG. A análise compreensiva da rede social da nutriz revelou que esta pode oferecer apoio/suporte ou não para o sucesso da lactação. Assim sendo, o apoio recebido foi expresso de várias formas: (1) Auxílio nas atividades domésticas; (2) Ajuda nos cuidados com o bebê; (3) Estímulo ao aleitamento; e (4) Orientações e conselhos. Nessa perspectiva, pensar em rede social implica conhecer o contexto sociocultural no qual a mulher-mãe está inserida, ampliando o olhar sobre a lactação, além de fornecer subsídios para a formulação de políticas públicas mais eficazes em prol do aleitamento.

VCO consumption did not acutely change energy metabolism and cardiometabolic risk markers when added to a mixed breakfast but promoted less appetitive responses.

Folate, vitamin B6, and vitamin B12 intake can be important regulators for obesity development. Thus, we investigated the possible association between the intake of these vitamins and the excess body weight or obesity prevalence in the participants of the Cohort of Universities in Minas Gerais (CUME project). This study analyzed cross-sectional data of 2695 graduates and postgraduates from universities in the state of Minas Gerais (801 men, 1894 women, ages 36.2 ± 9.4). The first step consisted of collecting data online, and the second step consisted of blood collecting in the subsample living in the city of Viçosa and its region (Minas Gerais). Excess body weight and obesity prevalence were 38.1% and 10.1%, respectively. Inadequate intake of folate, B6, and B12 were 12, 6.3, and 11.1%, respectively. Beans/lentils and French bread presented the highest contribution to folate intake (23.45% and 10.01%, respectively). Those individuals in the third tertile for folate intake (≥511.12 μg/d) had a lower excess body weight [prevalence ratio (PR): 0.79, confidence interval (CI): 0.71–0.8] and obesity prevalence (PR: 0.60, CI: 0.45–0.78). These associations were maintained when the sample was categorized by sex. In addition, serum folate was positively associated with dietary folate (p for trend = 0.032) and negatively associated with serum homocysteine (p for trend = 0.003) in the subsample. Dietary folate intake was negatively associated with excess body weight and obesity in CUME participants, indicating the relevance of this vitamin dietary assessment.
