CLOUD POINT EXTRACTION/PRECONCENTRATION OF COPPER IONS EXPLOITING THE FORMATION OF COMPLEXES WITH DMIT [4,5-DIMERCAPTO-1,3-DITHYOL-2-THIONATE]

CLOUD POINT EXTRACTION/PRECONCENTRATION OF COPPER IONS EXPLOITING THE FORMATION OF COMPLEXES WITH DMIT [4,5-DIMERCAPTO-1,3-DITHYOL-2-THIONATE]. The present study proposes a method for cloud point preconcentration of copper ions at pH 2.0 based on complexes formed with [4,5-dimercapto-1,3-dithyol-2-thionate] and subsequent determination by flame atomic absorption spectrometry (FAAS). Under optimal analytical conditions, the method provided limits of detection of 0.84 and 0.45 mu g L-1, by preconcentrating 12.0 and 24.0 mL of sample, respectively. The method was applied for copper determination in water samples, synthetic saliva, guarana powder, tea samples and soft drinks and the accuracy was assessed by analyzing the certified reference materials Dogfish Liver (DOLT-4) and Lobster Hepatopancreas (TORT-2).3581600160

Arterial hypertension and associated factors in patients submitted to myocardial revascularization

OBJECTIVE To identify the prevalence of arterial hypertension and associated factors in patients submitted to myocardial revascularization. METHOD Cross-sectional study using the database of a hospital in São Paulo (SP, Brazil) containing 3010 patients with coronary artery disease submitted to myocardial revascularization. A multiple logistic regression was performed to identify variables independently associated with hypertension (statistical significance: p1.3: (OR=1.37;CI:1.09-1.72). CONCLUSION A high prevalence of arterial hypertension and association with both non-modifiable and modifiable factors was observed

Educação em diabetes: papel e resultados das colônias de férias

Improving diabetes care is essential to preserve quality of life and longevity. The achievement of this goal depends on the diabetes education. Different health care centers have developed diabetes programmes based on regional characteristics and availability of resources. Our experience with educational summer camp (SC) for type 1 diabetic subjects is presented. The UNIFESP-ADJ SC aims to promote diabetes education at leisure with the participation of a multiprofessional team who has the opportunity to improve knowledge and skills in diabetes management. Seven-hundred-ninety subjects participated in 18 camps. The 9-day camp programme included adequate diet and exercise 3 times a day. Capillary glucose is monitored with appropriate insulin closes adjustments. The same questionnaire is applied at the beginning and end of the camping period in order to evaluate knowledge improvement in diabetes; they are invited to participate in educational daily meetings. Also the multiprofessional team meets every night for cases discussion. Anthropometric measurements, blood pressure, urine an blood samples are obtained. Individual recordings are provided to the respective families and physicians at the end of the camping period. The SCs have allowed diabetic subjects to recognize the possibility of a normal life. Improvement of knowledge in diabetes was confirmed by the comparison of questionnaires scores. They experienced the benefits of an adequate diet associated with exercise for glucose control and understood its importance to prevent long-term complications. Hypoglycemia occured more frequently, but they learned how to identify symptoms and to treat them. Blood pressure, plasma glucose and lipoproteins levels were reduced. The multiprofessional team recognized the role of diabetes education and developed skills to improve effectiveness of diabetes care. The complexity of diabetes treatment required the participation of the patient and its family in order to achieve metabolic control. Short-term benefits of diabetes education are seen by patients and their families. Assuming that metabolic control is necessary to prevent diabetic chronic complications, long-term benefits should be detected by the implementation of educational SCs for diabetic youngsters. The proposed modality of diabetes education in SCs showed to be reliable and effective, contributing to improve health of diabetic people and the quality of diabetes management. We concluded that such proposal should become more widespread.É essencial atuar na atenção ao indivíduo diabético, visando sua qualidade de vida e a longevidade. O sucesso desta meta depende da educação em diabetes (DM). Características regionais e disponibilidade de recursos fizeram com que centros de atenção ao DM criassem programas específicos de educação. Mostramos a experiência de educação de jovens com DM1 através de Colônias de Férias (CF) da UNIFESP-ADJ, mediante o convívio com equipe multiprofissional de saúde, que tem a oportunidade de adquirir experiência no manejo do DM. Um total de 790 jovens já participaram das 18 CF realizadas. Oferece-se 9 dias de lazer programado, com dieta adequada e exercícios nos 3 períodos do dia. Glicemia capilar é feita sobre a qual se baseiam ajustes nas doses de insulina. Questionário de avaliação de conhecimentos é aplicado no primeiro e último dias e ocorrem seminários abordando temas diversos. Reuniões da equipe visam discutir casos e condutas. São obtidas medidas antropométricas, pressão arterial e amostras de sangue e urina e relatórios fornecidos ao final. Para o jovem as CF representam oportunidade de conscientizar-se da possibilidade de uma vida normal. A melhora dos conhecimentos teóricos é comprovada pela comparação da pontuação obtida nos questionários. Observam os benefícios da alimentação adequada associada ao exercício e assimilam a importância do bom controle na prevenção de complicações crônicas. Vivenciam hipoglicemias, mas aprendem a programar suas doses segundo o exercício a ser realizado, identificar seus sintomas e tratá-la. Melhoram os níveis pressóricos, o controle glicêmico e o perfil lipídico. A equipe multiprofissional recebe subsídios para atuar com mais eficácia na educação do jovem e melhorar o relacionamento médico-paciente. As CF permitem reconhecer a complexidade do tratamento do DM e a necessidade de trabalho integrado com o paciente e sua família para a obtenção de bom controle metabólico. Assumindo-se que o controle metabólico é importante para a prevenção das complicações crônicas do DM, também a longo prazo benefícios da educação nas CF devem ser detectados. O modelo proposto de educação em DM através de CF se mostrou viável e eficaz, contribuindo para melhora da qualidade de vida do jovem diabético e formação de profissionais nesta área. Concluímos que esta proposta, já compartilhada por outros centros no Brasil, deva ser amplamente divulgada.Universidade Federal de São Paulo (UNIFESP) Escola Paulista de Medicina Departamentos de Medicina, Preventiva e de EnfermagemUNIFESP, EPM, Depto.s de Medicina, Preventiva e de EnfermagemSciEL
