Controle glicêmico em pacientes adultos com diabetes do tipo 1 em uma cidade brasileira: comparação entre abordagem multidisciplinar e endocrinológica de rotina

OBJECTIVE: To evaluate the metabolic control of a cohort of adult type 1 diabetes mellitus (T1DM) patients assisted in a public Diabetes Center (DC) that follows the rules of a national diabetes society. METHODS: We compared for one year the metabolic control and the characteristics of 175 T1DM patients attended by a multidisciplinary team in a DC (test group) with 30 patients assisted only by endocrinologists at a public endocrinology outpatient center (control group). RESULTS: The test group presented a larger proportion of well-controlled patients (p= 0.002). The proportions (test x control group) were as follows: 51.4% x 16.7% in the subgroup with A1C 8%. Patients assisted in the DC presented a likelihood 4.38 times higher of reaching levels of A1C up to 7%. CONCLUSIONS: This study shows the effectiveness of a DC and emphasizes the importance of education, adherence and multidisciplinarity as cornerstones for the treatment, showing that in developing countries it is possible to treat T1DM with satisfactory results.OBJETIVO: Avaliar o controle metabólico de uma coorte de pacientes adultos com diabetes do tipo 1 (DM1) atendidos em um Centro de Diabetes (CD) que segue as normas da Sociedade Brasileira de Diabetes. MÉTODOS: Foram comparados o controle glicêmico e as características de 175 pacientes com DM1 atendidos por uma equipe multidisciplinar em um CD (grupo teste) com 30 pacientes assistidos em um ambulatório de endocrinologia geral (grupo controle) durante um ano. RESULTADOS: O grupo teste apresentou uma maior proporção de pacientes bem controlados (p= 0,002). As proporções (grupo teste x grupo controle) foram: 51,4% x 16,7% no subgrupo com A1C 8%. Os pacientes atendidos no CD apresentaram probabilidade 4,38 vezes maior de atingir níveis de A1C até 7%. CONCLUSÃO: O estudo mostra a efetividade do CD e enfatiza a importância da educação, aderência e da multidisciplinaridade como pedras angulares do tratamento, mostrando ser possível tratar o DM1 nos países em desenvolvimento com resultados satisfatórios.Universidade Federal de São Paulo (UNIFESP)Universidade Federal de Juiz de Fora Departamento de FisiologiaUNIFESPSciEL

Characterisation of microbial attack on archaeological bone

As part of an EU funded project to investigate the factors influencing bone preservation in the archaeological record, more than 250 bones from 41 archaeological sites in five countries spanning four climatic regions were studied for diagenetic alteration. Sites were selected to cover a range of environmental conditions and archaeological contexts. Microscopic and physical (mercury intrusion porosimetry) analyses of these bones revealed that the majority (68%) had suffered microbial attack. Furthermore, significant differences were found between animal and human bone in both the state of preservation and the type of microbial attack present. These differences in preservation might result from differences in early taphonomy of the bones. © 2003 Elsevier Science Ltd. All rights reserved
