Impacto do controle glicêmico sobre as complicações associadas ao diabetes mellitus na osseointegração

The increased prevalence of diabetic individuals has become a public health problem. Diabetes Mellitus is a metabolic disorder characterized by an increase in plasma glucose levels. It impairs the physiological equilibrium in utilization of carbohydrate by tissues. The persistent hyperglycemia can produce deleterious effects on bone formation due the microvascular complication. The present paper reviews the bibliography linking the impact of glycemic control at complications associated at diabetes mellitus on osseointegration. In experimental models of diabetes it was observed a reduced level of bone-implant contact. This failure can be reduced by means of hyperglycemia control. Also, several studies point the beneficial effect of coated implant on osseointegration process. It is necessary to take special care into account for the placement of implants in diabetic patient and improve the percentages of implant survival. A rigorous control of plasma glycaemia, together with other measures, like as absence of chronic complications, good oral hygiene and regular medical follow-up has been related to rising the percentages of successful in diabetic patients.

Diabetes mellitus: avaliação do conhecimento de cirurgiões-dentistas em municípios de três estados brasileiros

Introduction: Pathological changes in the bucal cavity associated with Diabetes mellitus (DM) may include gingivitis, periodontal disease, salivary gland dysfunction and xerostomia (dry mouth), susceptibility to bucal infections, burning mouth syndrome, and altered taste. Objective: This study assessed the technical and scientific knowledge of dentists working in primary care in the National Health System (SUS) on the DM. Material and method: The study was conducted in the municipalities of Birigui-SP, Maringá-PR and TrêsLagoas-MS, with the participation of 76 dentists working in the SUS primary care system.These professionals agreed to answer to a questionnaire developed for this study and the results of the questions were submitted to a quantitative analysis. Result: Showed that 94.7% were in contact with diabetic patients; 97.4% know what is DM; about other types of DM, 77.6% said they know, the most mentioned (by 55.9%) was the gestational DM. The DM2 was indicated as the most prevalent by 59.2%; the normal range of fasting blood glucose level was quoted correctly by 2.6% of the participants; obesity was reported by 98.7% of participants as a risk factor for DM; 96.0% stated correctly what are the main signs and symptoms related to Diabetes; periodontal disease was reported by 92.1% as an bucal manifestation in diabetic patients. Conclusion: The dentist needs to develop specific knowledge about DM, being able to identify normal levels of blood glucose and ready to identify and meet the bearer of DM.

Diabetes mellitus gestacional: enfoque nos novos critérios diagnósticos

Alterations in maternal metabolism are important in order to supply the demands of the fetus. However, pregnant women with some degree of insulin resistance, such as in cases of overweight/obesity, central obesity and polycystic ovaries syndrome, associated to the action of anti-insulin placental hormones, contribute to a case of hyperglycemia of varied intensity, characterizing gestational diabetes mellitus (GDM) and leading to adverse effects both maternal and fetal. At the absence of a universal consensus to the tracking and diagnosis of GDM, this review had the purpose of listing the various protocols that have been proposed, as well as highlighting the risk factors associated with GDM and its complications. The most recent protocol is the one from the American Diabetes Association, with changes that would be justified by the alarming raise in worldwide obesity and, consequently, the potential increase to the occurrence of type 2 diabetes mellitus, not always diagnosed before the gestational period. The intention of this protocol is to identify the gestating women that could benefit from hyperglycemia control, improving the prognostic of these pregnancies and preventing future complications for mothers and their children.

Prescription patterns for diabetes mellitus and therapeutic implications: a population-based analysis

Objective: To analyze drug prescriptions for insulin and oral antidiabetic drugs in type 1 and type 2 diabetes mellitus patients seen in the Brazilian Public Healthcare System (Unified Health System - SUS) in Ribeirao Preto, SP, Brazil. Subjects and methods: All the patients with diabetes seen in the SUS in the western district of Ribeirao Preto, SP, Brazil between March/2006 and February/2007 were included in the study. Results: A total of 3,982 patients were identified. Mean age of the patients was 60.6 years, and 61.0% were females. Sixty percent of the patients were treated with monotherapy. Doses of oral antidiabetic drugs were lower in monotherapy than in polytherapy. Ten patients received doses of glibenclamide or metformin above the recommended maximum doses, and in elderly patients there was no reduction in drug doses. Conclusion: Monotherapy with oral antidiabetic drugs was the predominant procedure, and the doses were not individualized according to age. Arq Bras Endocrinol Metab. 2012;56(2):120-7

Gene expression profiles displayed by peripheral blood mononuclear cells from patients with type 2 diabetes mellitus focusing on biological processes implicated on the pathogenesis of the disease

Patients with type 2 diabetes mellitus (T2DM) exhibit insulin resistance associated with obesity and inflammatory response, besides an increased level of oxidative DNA damage as a consequence of the hyperglycemic condition and the generation of reactive oxygen species (ROS). In order to provide information on the mechanisms involved in the pathophysiology of T2DM, we analyzed the transcriptional expression patterns exhibited by peripheral blood mononuclear cells (PBMCs) from patients with T2DM compared to non-diabetic subjects, by investigating several biological processes: inflammatory and immune responses, responses to oxidative stress and hypoxia, fatty acid processing, and DNA repair. PBMCs were obtained from 20 T2DM patients and eight non-diabetic subjects. Total RNA was hybridized to Agilent whole human genome 4x44K one-color oligo-microarray. Microarray data were analyzed using the GeneSpring GX 11.0 software (Agilent). We used BRB-ArrayTools software (gene set analysis - GSA) to investigate significant gene sets and the Genomica tool to study a possible influence of clinical features on gene expression profiles. We showed that PBMCs from T2DM patients presented significant changes in gene expression, exhibiting 1320 differentially expressed genes compared to the control group. A great number of genes were involved in biological processes implicated in the pathogenesis of T2DM. Among the genes with high fold-change values, the up-regulated ones were associated with fatty acid metabolism and protection against lipid-induced oxidative stress, while the down-regulated ones were implicated in the suppression of pro-inflammatory cytokines production and DNA repair. Moreover, we identified two significant signaling pathways: adipocytokine, related to insulin resistance; and ceramide, related to oxidative stress and induction of apoptosis. In addition, expression profiles were not influenced by patient features, such as age, gender, obesity, pre/post-menopause age, neuropathy, glycemia, and HbA(1c) percentage. Hence, by studying expression profiles of PBMCs, we provided quantitative and qualitative differences and similarities between T2DM patients and non-diabetic individuals, contributing with new perspectives for a better understanding of the disease.
