Resumo Este estudo apresenta as concepções e práti-cas de educação em saúde de profissionais da Estraté-gia Saúde da Família de um município de pequeno porte no estado do Rio Grande do Norte. A pesquisa foi realizada com 18 profissionais de nível superior: médicos, enfermeiros e cirurgiões-dentistas entre outubro e dezembro de 2013. Fez-se uso da entrevista semiestruturada e da observação norteada em princí-pios etnográficos. A análise de conteúdo de Bardin subsidiou o exame do material. Os resultados apontam que as concepções e práticas de educação em saúde são orientadas por uma 'educação bancária', pautada na transmissão e reprodução de conhecimentos. As ações educativas são, eminentemente, direcionadas à prevenção de doenças e conduzidas, majoritariamente, por enfermeiros e estudantes de graduação em estágio nas Unidades Saúde da Família. Observou-se que a educação em saúde praticada não instrumentaliza os usuários para que desenvolvam autonomia e possam tornar-se sujeitos de suas vidas, de sua história. Palavras-chave educação em saúde; saúde da família; prática profissional.Abstract This study presents the educational concepts and practices in health of professionals in the Family Health strategy at a small city in the state of Rio Grande do Norte, Brazil. The survey was conducted among 18 high-level professionals, among whom physicians, nurses, and dentists, between October and December 2013. Semi-structured interviews and observation guided by ethnographic principles were used. Bardin content analysis supported the analysis of the material. The results show that the health education concepts and practices are guided by a 'banking education' that is based on the transmission and reproduction of knowledge. The educational activities are eminently aimed at disease prevention and conducted largely by nurses and graduate students taking internships at the Family Health Units. It was observed that the health education practiced does not instrumentalize users to develop autonomy and become the subjects of their lives and of their history.

Alginates isolated from Sargassum vulgare, present a strong antitumor activity, associated with kidney reversible damage, as analysed by histopathology of treated animals. In the present study, the renal alteration mechanisms of S. vulgare alginates were investigated using the isolated perfused rat kidney and the isolated perfused rat mesenteric blood vessel methods. The results showed that the effects of Sargassum vulgare low viscosity (SVLV) alginate were more potent than those of Sargassum vulgare high viscosity (SVHV) alginate in the isolated rat kidney. The SVLV alginate caused considerable changes in renal physiology, as shown by an increase in parameters such as perfusion pressure, renal vascular resistance, glomerular filtration rate, urinary flow and sodium, potassium and chloride excretion and by reduction of chloride tubular transport. The effects of SVHV were weaker than those of SVLV. The effects of SVLV on kidney could be related to direct vascular action as demonstrated with SVLV alginate on mesenteric blood vessels. In conclusion, the Sargassum vulgare alginate altered the renal function parameters evaluated. S. vulgare low viscosity alginate renal effects were more potent than S. vulgare high viscosity alginate. It is suggested that physicochemical differences between SVHV and SVLV could explain the differences found in the results.

-Multidisciplinaridade. RESUMO A inserção dos sujeitos nos cenários de prática na Atenção

Resumo O trabalho interprofissional é necessário para a consolidação do modelo de atenção à saúde, porém o cirurgião-dentista encontra muitos desafios para trabalhar em equipe. Este estudo objetivou conhecer o interprofissionalismo, no âmbito da saúde bucal, entre os trabalhadores graduados da Estratégia Saúde da Família. Tratou-se de um estudo exploratório e transversal, com abordagem qualitativa, desenvolvido com 39 profissionais graduados da Atenção Básica do município de Icó, Ceará, Brasil. Os sujeitos pesquisados declararam uma deficiência na manutenção técnica nas unidades, a recorrente falta de insumos e a demanda excessiva de usuários como elementos que prejudicam o trabalho em equipe, assim como a inexistência de um plano de cargos, carreiras e salários, sendo um motivo de descontentamento entre os profissionais. Todos consideraram importante o trabalho interprofissional e sugeriram reuniões periódicas, atividades compartilhadas mais frequentes e capacitações como forma de intensificar essa ação. Apesar de o trabalho interprofissional ser reconhecido como fundamental para as ações de cuidado, é necessário mais comprometimento e apoio da gestão.

Objective: The present work is an analytical and prospective study on the determination of HDL-cholesterol through two different methodologies, precipitation and direct method, in a group of 51 patients attended by a school laboratory. Method: For the determination of these analytes, two methodologies were used: direct method and precipitation method, because it has been observed experimentally discrepancies in the values referring to the results of determination of cholesterol-HDL when comparing the results from the two methodologies, which can lead to a failed therapy. Result: Of the 51 samples analyzed, 38 (74.5%) were female and 13 (25.5%) were male. The results were divided into groups by age group, in order to verify a possible difference between the groups, the age range was 11 to 88 years. When the HDL-cholesterol values obtained by the two different methods were evaluated, there was a significant difference (p <0.0001) in the HDL-cholesterol values between the direct method (56.06 ± 1.653) and the precipitation method (39.35 ± 1.193). Conclusion:For HDL values, it was possible to verify that there is a significant increase between the HDL-cholesterol values obtained by the direct method in relation to the method by precipitation independent of variables such as sex and age group. This way further studies are needed in order to find a pattern of variation between the methods and allow the adequacy of the results through a correction factor or even new reference values.

Abstract The aim of this study was to evaluate the impact of creatine supplementation (CS) on renal function in young, healthy, and active subjects. We used a randomized, double-blind, placebo-controlled clinical trial as the study design. Thirty-six healthy male university students were recruited and divided into three groups: group placebo, group G3 (3 g/day of CS), and group G5 (5 g/day of CS). To assess renal function, new kidney biomarkers, kidney injury molecule-1 (KIM-1) and monocyte chemoattractant protein-1 (MCP-1), were quantified. Serum albumin, serum creatinine, serum urea, estimated glomerular filtration rate (eGFR), proteinuria, and albuminuria were also measured. All groups were evaluated at two times: prior CS or placebo (pre) and after 35 days on CS or placebo (post). After 35 days of intervention, all characteristics were maintained without significant difference (P &gt; 0.05) between the groups, including serum creatinine, eGFR, and more sensitive kidney biomarker concentrations (KIM-1 and MCP-1). The paired analysis showed that the supplemented groups (G3 and 5G) had increased serum creatinine and decreased eGFR levels (P &lt; 0.05). However, the values were still within the normal reference range. In conclusion, the results of renal function evaluation did not show any difference between the evaluated groups. Increased serum creatinine and decreased eGFR levels in CS groups can be explained by increased creatine stores and metabolism, since creatinine is a by-product of creatine metabolism. These findings indicate that the use of CS at doses of 3 g and 5 g/day for a short period (35 days) is safe and did not impair the kidneys or renal function in young healthy subjects.
