Diabetes mellitus e esteatose hepática em ratos: efeitos de um protocolo de treinamento aeróbio

The present study aimed to analyze the effects of exercise performed at aerobic/anaerobic transition on non-alcoholic hepatic steatosis (NAHS) markers in diabetic rats. Adult (60 days) male Wistar rats were divided into 4 groups: sedentary control (SC), trained control (TC), sedentary diabetic (i.v. alloxan injection) (SD) and trained diabetic (TD). At the beginning of the experiment, all the animals were submitted to maximal lactate steady state test (MLSS) in order to identify the aerobic/anaerobic metabolic transition during swimming exercise. The trained groups were submitted to swimming, supporting overloads (% of body weight – b.w.) equivalent to MLSS intensity, 1h/day, 5 days/week, during 8 weeks. We analyzed: serum ALT, AST, albumin, glucose and free fat acids (FFA), body weight and total lipid concentrations in the liver. The diabetic groups showed higher (ANOVA two-way, p<0.05) serum glucose (SD=200% and TD= 150%) and weight loss (SD= 15.0% and TD= 8.5%) compared to controls and the SD showed higher glucose concentration and weight loss when compared to TD. The work load (% b.w.) equivalent to the MLSS was lower in TD (4.7%) than in TC (5.6%) group. The NAHS markers (U/L) did not show... (Complete abstract click electronic access below)

Angiotensin converting enzyme polymorphism in type 2 diabetes mellitus

This study was undertaken to assess the frequency of angiotensin converting enzyme (ACE) insertion/deletion (I/D) polymorphism in patients with type 2 diabetes mellitus. A total of 162 patients with type 2 diabetes and 160 individuals without this disease were analyzed. From the diabetes group, 81 patients with cardiovascular risk (according to American Diabetes Association parameters) were selected to form another subgroup. For polymorphism identification, two polymerase chain reactions were performed: one reaction to identify all genotypes and a second one to confirm the presence of the I allele. The observed genotype frequencies were as follows: diabetes group I/I (19.1%), I/D (52.5%), D/D (28.4%); control group I/I (12.5%), I/D (55.6%), D/D (31.9%); and diabetes with cardiovascular risk group I/I (16.0%), I/ D (59.3%), D/D (24.7%). No statistically significant difference was observed between the allelic and genotypic frequencies in the analyzed groups. Previous studies reported an association between the D allele and type 2 diabetes in Caucasian and East Asian populations. However, in mixed populations, such as those found in Brazil, such an association was not found. This fact does not discard the need for more studies on the frequencies of this polymorphism in the Brazilian population and the associations with risk factors, which can compromise the quality of life of diabetes patients

Assessment of structural cardiac abnormalities and diastolic function in women with gestational diabetes mellitus

Background: The main manifestation of hyperglycaemia during pregnancy is gestational diabetes mellitus. It can herald diabetes mellitus type 2 and its deleterious long-term effects, such as hypertension and cardiovascular disease. The aim of this study was to assess diastolic function in women with gestational diabetes mellitus, one of the first signs of future cardiovascular disease.Methods: A total of 21 women with gestational diabetes mellitus and 23 healthy pregnant women (control group) between 34 and 37weeks of gestation underwent echocardiographic assessment. The diagnosis of gestational diabetes mellitus was made in agreement with the American Diabetes Association criteria. Echocardiographic images obtained were analysed according to the criteria of the American Society of Echocardiography. Data were analysed using Pearson correlation coefficient, analysis of variance and Student's t-test.Results: Women with gestational diabetes mellitus had higher posterior wall and interventricular septum thickness, increased left ventricular mass and left ventricular mass index, lower early diastolic annular velocity and early diastolic annular velocity/late diastolic annular velocity ratio. There was a positive correlation between left ventricular mass index and fasting glucose and pregnancy body mass index.Conclusion: Patients with gestational diabetes mellitus seem to have a different diastolic profile as well as a mildly dysfunctional pattern on echocardiogram, which may show a need for greater glycaemic control.

TNFa-e microsatellite, HLA-DRB1 and-DQB1 alleles and haplotypes in Brazilian patients presenting recently diagnosed type 1 diabetes mellitus

TNF microsatellite and HLA class II polymorphisms were studied in 28 recently diagnosed Brazilian patients presenting type 1 diabetes mellitus (T1DM) and in 120 healthy controls. TNFa-e and HLA-DRB1/DQB1 alleles were identified using sets of sequence-specific primers. Compared to controls, the DRB1* 03 and DQBI*02 allele groups, TNFa1 allele, and the TNFa4-b5-c1-d4-e3 and TNFa10-b5-c1-d4-e3 haplotypes were overrepresented in patients. TNF microsatellite together with HLA polymorphisms is associated with type 1 diabetes in Brazilian patients, corroborating the participation of the MHC genes in disease susceptibility.

Species diversity of yeast in oral colonization of insulin-treated diabetes mellitus patients

The aim of this study was to investigate oral yeast colonization, antifungal susceptibility and strain diversity in insulin-dependent diabetes mellitus patients (175), as well as to evaluate the influence of dental prostheses. Oral rinse samples were cultured on selective media, in order to isolate, count and identify the yeasts recovered. More than half of the diabetic subjects (53%) carried significant amounts of Candida cells in the buccal cavity and these organisms were recovered at higher densities in diabetics wearing dentures. A total of 93 yeast strains were isolated from these patients, including: Candida spp. (n = 89); Pichia (n = 02); Trichosporon (n = 1), and Geotrichum (n = 1). C. albicans represented 56% of these strains, non-albicans Candida 39.8%, and other genera of yeast 4.3%. C. albicans was prevalent, followed by C. parapsilosis, C. tropicalis, C. glabrata, C. krusei, C. rugosa and C. guilliermondii. Agar disk-diffusion tests of the susceptibility of non-albicans Candida and other genera of yeast to fluconazole showed resistance in 21.9%, mainly in C. rugosa (100%), C. glabrata (57%) and C. krusei (50%). Local oral factors, such as the presence of dentures, in association with diabetes, seemed to have the effect of increasing the amount and variety of Candida species in the oral cavities, mainly those with lower drug susceptibilities.

Diabetes mellitus juvenil: a experiência de familiares de adolescentes e pré-adolescentes

Este estudo foi desenvolvido com o objetivo de investigar a experiência de cuidar de adolescentes e pré-adolescentes portadores de diabetes tipo I, na perspectiva dos seus familiares. Foi utilizada a abordagem fenomenológica, modalidade de pesquisa qualitativa que se propõe a compreender os significados das experiências vividas. Foram entrevistados dez pais (9 mães e 1 pai) em hospital de ensino do interior paulista. A experiência de cuidar do filho com diabetes emerge das convergências das descrições dos participantes, sendo descrita em três temas principais: o universo da doença; relação com as pessoas; reflexão sobre a experiência vivida. Os participantes descrevem suas dificuldades e estratégias para manterem a família unida e ainda oferecer suporte aos filhos. Eles acreditam que têm que aceitar e enfrentar os desafios, além de estimularem os filhos para sua segurança e qualidade de vida. Os dados mostraram a necessidade de um suporte profissional, além de um espaço para a discussão de temas tanto para as crianças com diabetes como para seus familiares.

Comprovação do efeito antioxidante de plantas medicinais utilizadas no tratamento do Diabetes mellitus em animais: artigo de atualização

Diabetes mellitus (DM) é uma síndrome de etiologia múltipla caracterizada por hiperglicemia crônica. Esta hiperglicemia induz o aumento na produção de espécies reativas de oxigênio (ERO) e diminuição das defesas antioxidantes. Devido às complicações causadas pelo diabete, muitos indivíduos optam por terapias alternativas à base de plantas medicinais para amenizar seus efeitos. Sendo assim, nesta revisão de literatura, foram analisados e descritos diversos trabalhos experimentais com a utilização de animais diabéticos para comprovar os efeitos antioxidantes de algumas dessas plantas e verificar se os títulos e resumos disponibilizados nos artigos são compatíveis aos objetivos de nossa busca.
