Em revisão crítica da literatura sobre a educação para o autocuidado e autocontrole no diabetes, procura-se apontar a inadequação das abordagens tradicionais da aderência ao tratamento e da transmissão de informações frente à complexidade do autocuidado em condições de cronicidade. Explora-se a influência das Ciências Sociais sobre o campo de estudo das doenças crônico-degenerativas, em geral, e do diabetes, em particular. Nesta perspectiva, pode-se reconhecer uma incorporação dos campos disciplinares da Antropologia e Sociologia em pesquisas mais orientadas para o indivíduo, em sua condição de portador, e a experiência que desenvolve nesse processo. Há certa inflexão, mais recente, no campo de pesquisas em educação em saúde no diabetes, com a introdução de estratégias que buscam valorizar a experiência e a autonomia dos pacientes como sujeitos de seu cuidado. Neste artigo, discute-se a estratégia do empoderamento na educação para o autocuidado e autocontrole no diabetes, como uma modalidade de prática de natureza mais dialógica e de maior respeito à autonomia moral e cognitiva do portador.

Chorea and ballism are movement disorders that result from a variety of conditions. Hyperglycemia is an unusual recognized cause of these movement disorders. We report 3 cases of new-onset choreaballism induced by nonketotic hyperglycemia in elderly patients, highlighting that chorea may be the first manifestation of undiagnosed decompensated diabetes mellitus.

This study analyzed the effects of overground walking training at ventilatory threshold (VT) velocity on glycaemic control, body composition, physical fitness and lipid profile in DM2 women. Nineteen sedentary patients were randomly assigned to a control group (CG; n=10, 55.9±2.2 years) or a trained group (TG; n=9, 53.4±2.3 years). Both groups were subjected to anthropometric measures, a 12-h fasting blood sampling and a graded treadmill exercise test at baseline and after a 12-week period, during which TG followed a training program involving overground walking at VT velocity for 20-60min/session three times/week. Significant group×time interactions (P<0.05) in glycated hemoglobin (HbA1c), body mass, body mass index (BMI), peak oxygen uptake (VO 2peak) and exercise duration were observed as effects of training exercise, whereas intervention did not induced significant changes (P>0.05) in fasting blood glucose, submaximal fitness parameters and lipid profile. Our results suggest that overground walking training at VT velocity improves long term glycaemic control, body composition and exercise capacity, attesting for the relevance of this parameter as an effective strategy for the exercise intensity prescription in DM2 population. © 2011 Elsevier B.V.

Periodontitis is an inflammatory disease caused by pathogenic microorganisms and characterized by the destruction of the periodontium. Obese individuals have an increased risk of periodontitis, and elevated circulating levels of adipokines, such as nicotinamide phosphoribosyltransferase (NAMPT), may be a pathomechanistic link between both diseases. The aim of this in vitro study was to examine the regulation of periodontal ligament (PDL) cells by NAMPT and its production under inflammatory and infectious conditions. NAMPT caused a significant upregulation of 9 genes and downregulation of 3 genes, as analyzed by microarray analysis. Eight of these genes could be confirmed by real-time PCR: NAMPT induced a significant upregulation of EGR1, MMP-1, SYT7, ITPKA, CCL2, NTM, IGF2BP3, and NRP1. NAMPT also increased significantly the MMP-1 and CCL2 protein synthesis. NAMPT was significantly induced by interleukin-1β and the periodontal microorganism P. gingivalis. NAMPT may contribute to periodontitis through upregulation of MMP-1 and CCL2 in PDL cells. Increased NAMPT levels, as found in obesity, may therefore represent a mechanism whereby obesity could confer an increased risk of periodontitis. Furthermore, microbial and inflammatory signals may enhance the NAMPT synthesis in PDL cells and thereby contribute to the increased gingival and serum levels of this adipokine, as found in periodontitis. © 2013 Marjan Nokhbehsaim et al.

Several types of sex chromosome systems have been recorded among Gymnotiformes, including male and female heterogamety, simple and multiple sex chromosomes, and different mechanisms of origin and evolution. The 1X1X2X2/X1X2Y systems identified in three species of this order are considered homoplasic for the group. In the genus Brachyhypopomus, only B. gauderio presented this type of system. Herein we describe the karyotypes of Brachyhypopomus pinnicaudatus and B. n. sp. FLAV, which have an X1X1X2X2/X1X2Y sex chromosome system that evolved via fusion between an autosome and the Y chromosome. The morphology of the chromosomes and the meiotic pairing suggest that the sex chromosomes of B. gauderio and B. pinnicaudatus have a common origin, whereas in B. n. sp. FLAV the sex chromosome system evolved independently. However, we cannot discard the possibility of common origin followed by distinct processes of differentiation. The identification of two new karyotypes with an X1X1X2X2/X1X2Y sex chromosome system in Gymnotiformes makes it the most common among the karyotyped species of the group. Comparisons of these karyotypes and the evolutionary history of the taxa indicate independent origins for their sex chromosomes systems. The recurrent emergence of the X1X1X2X2/X1X2Y system may represent sex chromosomes turnover events in Gymnotiformes.

The main objective of the presented study is the design of a analog multiplier-divider as integrant part of the type-reducer circuit of type-2 fuzzy controller chip. The proposed circuit is a multiplier/divider which operates in current mode, in the CMOS technology with a supply voltage of 1.8 V.The circuit simulation was performed in PSPICE software with simulation model provided by AMS (Austria Mikro Systems International) in CMOS technology 0.35μm

Objective. The aim of this study was to investigate the local and systemic expression of CC-chemokine ligand 3 (CCL3) and its receptors (CCR1 and CCR5) in tissue samples and peripheral blood mononuclear cells of recurrent aphthous stomatitis (RAS) patients. Study Design. This case-control study enrolled 29 patients presenting severe RAS manifestations and 20 non-RAS patients proportionally matched by sex and age. Total RNA was extracted from biopsy specimens and peripheral blood mononuclear cells for quatitative reverse-transcription polymerase chain reaction. The data obtained by relative quantification were evaluated by the 2(-Delta Delta Ct) method, normalized by the expression of an endogenous control, and analyzed by Student t test. Results. The results demonstrated overexpression in RAS tissue samples of all of the chemokines evaluated compared with healthy oral mucosa, whereas the blood samples showed only CCR1 overexpression in RAS patients. Conclusions. These findings suggest that the increased expression of CCL3, CCR1, and CCR5 may influence the immune response in RAS by T(H)1 cytokine polarization.

Background: Albuminuria has been considered a sine qua non condition for the diagnosis of diabetic nephropathy (DN) and has been widely used as a surrogate outcome of chronic kidney disease (CKD). However, recent data suggest that albuminuria may fail as a biomarker in a subset of patients, and the search for novel markers is intense. Methods: We analyzed the role of urinary RBP and of serum and urinary cytokines (TGF-beta, MCP-1 and VEGF) as predictors of the risk of dialysis. doubling of serum creatinine or death (primary outcome. PO) in 56 type 2 diabetic patients with macroalbuminuric DN. Results: Mean follow-up time was 30.7 +/- 10 months. Urinary RBP and MCP-1 were significantly higher in patients presenting the PO, whereas no difference was shown for TGF-beta or VEGF. In the Cox regression, urinary RBP. MCP-1 and VEGF were positively associated and serum VEGF was inversely related to the risk of the PO. However, after adjustments for creatinine clearance, proteinuria, and blood pressure only urinary RBP (OR 11.6; 95% CI 2.7-49.2, p = 0.001 for log RBP) and urinary MCP-1 (OR 11.0; 95% CI 1.6-76.4, p = 0.02 for log MCP-1) remained as significant independent predictors of the PO. Conclusion: Urinary RBP and MCP-1 are independently related to the risk of CKD progression in patients with macroalbuminuric DN. Whether these biomarkers have a role in the setting of normoalbuminuria and microalbuminuria in DN should be further investigated. (C) 2012 Elsevier Inc. All rights reserved.
