Doença periodontal, diabete mellitus e hipertensão em gestantes usuárias do Sistema Único de Saúde (SUS)

Purpose: To evaluate the association among periodontal disease, diabetes mellitus and arterial hypertension in pregnant women users of the Brazilian Health System (SUS). Methods: The sample consisted of 86 women, with pregnant age between the 4th and 7 th month, submitted to pre-natal attendance in Health Basic Unities (HBUs). Periodontal condition was evaluated by 2 calibrated researchers (Kappa = 0.91) through the Community Periodontal Index (CPI). A sphygmomanometer was used to check the arterial pressure, what was accomplished by the professionals from the HBUs; glycemia test was accomplished through a blood sample collected from the middle finger with a disposable lancet adapted to a lance device (Accu-Chek Softclix Pro; Roche, USA), and for checking the glycemia level, a glycemia monitor was used (Accu-Chek Advantage II, Roche, USA). Data were written on a numbered register form, avoiding patient identification. After, the same data were statistically analyzed through the Fisher Exact Test, in order to evaluate the existence of association between the variables blood glucose and periodontal disease. In this test, a significance level of 0,05 was adopted. Results – Most of the pregnant woman presented periodontal health (58,1%); 41,9% of the research subjects showed at least one sign of periodontal disease, with 31,4% presenting gingivitis and 10,5% periodontitis. Hyperglycemia was detected in 51,2% and it was not found a value of arterial pressure higher than what is considered to be normal. Conclusion: it was not verified a significant association among the presence of periodontal disease, glycemia alteration and arterial hypertension in pregnant women who comprised this research.

The increase of elderly population in Brazil and all around the world shows the need of reviewing the health cares in order to get a better quality of life. Objective: To evaluate lifestyle and health care of elderly participants of UNATI, Franca, SP. Methods: Sixty elderlies answered a questions about socio-economic issues, health care, food consumption habits and lifestyle, after, they were submitted to anthropometric and laboratory tests. Results: There was a prevalence of women (85%), aged between 60-69 years old (60%), up to high school (60%), retired (65%), income up to 5 minimum wage (73.4%). Most seniors assessed medical care (65%) were in use of long-term medicines (78.3%), they reported to control blood pressure (80%) and to not smoke (100%). About 71.7% people believed to have a healthy diet, 97% took meals at home, 85% chose and prepared their own food, 65% had 5-6 meals/day, 63% drank 1L of water/day, 90% had bowel function and 43.3% practices a regular physical activity. Only 13.3% have done hormone replacement therapy, 18.3% take dietary supplements and 21.7% drink alcoholic drinks. The participants presented a BMI of 27.49 ± 4.5kg/m², prevalence of overweight and eutrophy, which values decreased with age. Leg circumference (LC) (36.27 ± 3.84 cm), Arm circumference (AC) (31.39 ± 4.08 cm) and triceps skinfolds (TS) (20.58±7.54mm) values were suit in most cases (96.7, 85 and 83.3%, respectively). Serum total cholesterol values were 198.53 ± 35.2mg/dL, 55% were considered optimum. About 63.3% and 68.3% of the elderlies, respectively, presented a high density lipoproteins (HDL) (53.58± 10.9mg/dL) and triglycerides (TG) (143.97 ± 92.37mg/dL) according to the recommendation and 51.7% of the elderlies had normal glycemia, 38.3% had risk and 10% showed high blood glucose, indicating diabetes. Conclusion: Many elderlies had body mass index (BMI) above normal, indicating overweight or obesity, but the participants can be considered healthy because of AC, LC and TS values, diet habits, health care and lifestyle.

Effect of the consumption of a symbiotic shake on the intestinal microflora of erdely people

The consumption of foods containing probiotic and prebiotic ingredients is growing consistently every year, and in view of the limited number of studies investigating their effect in the elderly. Objective The objective of this study was to evaluate the effect of the consumption of a symbiotic shake containing Lactobacillus acidophilus, Bifidobacterium bifidum and fructooligosaccharides on glycemia and cholesterol levels in elderly people. Methods A randomized, double-blind, placebo-controlled study was conducted on twenty volunteers (ten for placebo group and ten for symbiotic group), aged 50 to 60 years. The criteria for inclusion in the study were: total cholesterol > 200 mg/dL; triglycerides > 200 mg/dL and glycemia > 110 mg/dL. Over a total test period of 30 days, 10 individuals (the symbiotic group) consumed a daily dose of 200 mL of a symbiotic shake containing 108 UFC/mL Lactobacillus acidophilus, 108 UFC/mL Bifidobacterium bifidum and 2 g oligofructose, while 10 other volunteers (the placebo group) drank daily the same amount of a shake that did not contain any symbiotic bacteria. Blood samples were collected 15 days prior to the start of the experiment and at 10-day intervals after the beginning of the shake intake. The standard lipid profile (total cholesterol, triglycerides and HDL cholesterol) and glycemia, or blood sugar levels, were evaluated by an enzyme colorimetric assay. Results The results of the symbiotic group showed a non-significant reduction (P > 0.05) in total cholesterol and triglycerides, a significant increase (P < 0.05) in HDL cholesterol and a significant reduction (P < 0.05) in fasting glycemia. No significant changes were observed in the placebo group. Conclusion The consumption of symbiotic shake resulted in a significant increase in HDL and a significant decrease of glycemia.

Resposta crônica e aguda da glicemia a um protocolo de treinamento misto para melhora da saúde de diabéticos tipo 2

The objective of the research was to evaluate the effect of a training program of physical exercises mixed (aerobic / anaerobic conditioning circuit-break with active), including exercises, walking, weight training and Swiss ball, caused about possible changes in their metabolic system, as changes acute and chronic, individuals bearers of DM2. The methodology used is a model of experimented design of pretest and post-test applied to the group. The blood glucose levels were analyzed in fasting pre-test and post-test, and capillary glycemia in three periods of physical exercise: pre, during and post training, and the statistical processing done by the use of Statistical Software for PC-For SPSS ® Windows ®, V. 12.0 .. With the result has been a drop in the values significant glucometers between 6 weeks of training, with a negative delta average of 68 mg / dl. Furthermore, similar results were also found variations in the daily glycemic between the moments before and after the training session acute. Thus we find that, regardless of the biological mechanism responsible, the program mixed aerobic and anaerobic conditioning circuit-break with active was effective in reducing and controlling chronic and acute glycemic of subjects type 2 diabetic.

Efeitos do treinamento misto na promoção da saúde e sua interferência no perfil lipidêmico em indivíduos diabéticos tipo 2

Diabetes is a chronic disease that currently affects 171 million individuals approximately worldwide, with projection to reach 366 million people in 2030, increasing the prevalence of 2.8% in 2000 to 4.4%. The dyslipidemia is certainly one of the associated metabolic alterations most important, if we consider the main cause of death in Diabetes - the cardiovascular disease (CVD). One of the prevention and help factors in the Diabetes treatment and in the fall of associated complications is the physical exercise, which contributes to a better life quality to the diabetic. The main objective of the work was to evaluate the effect of a mixed physical exercises training program (aerobic/anaerobic with pause-active), including walking exercises, weightlifting and swiss ball, about possible changes in the blood lipid profile of adult individuals type 2 diabetics. The methodology used an experimental model of pre-test and post-test applied to the group. The data were first analyzed in a descriptive way for the normalization and the elaboration of averages and sample diversions. The sample was subdivided in two moments, being one pre and other post then weeks of training. After these procedures, the results of the values of the lipidic profile and glycemia were compared between the pairs pre and post training (test T Student, pair data), non-parametric. With the study, we can conclude that in despite of the low uptake of participants in the search, for reasons already cited, and the great age difference between them, the found results were partially satisfactory, because we achieved significant changes only in the glycemic variables, but we suggest future studies in the molds here proposed.

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.

Clinical and nutritional status in the late postoperative of pancreaticoduodenectomy. Influence of pylorus preservation procedure

PURPOSE: To evaluate the nutritional status of patients in the late postoperative period of pancreaticoduodenectomy (PD) and compare the long-term outcome according to pylorus-preserving (PPPD) or the standard technique (SPD) in which the pylorus is resected. METHODS: This prospective study was conducted twelve months prior or more in patients who had underwent PD (PD Group, n=15) and health volunteers (Control Group, n=15). At a post hoc analysis, the PD Group was divided in PPPD Subgroup (n=9) and SPD Subgroup (n=6), according to the PD techniques. Gastrointestinal complaints and nutritional status were evaluated, apart from a biochemical assessment; Student t-test or Mann-Whitney test were used. RESULTS: The patients recovered their body weight and the gastrointestinal complaints were uncommon. The PD Group showed higher energy and protein intake even though BMI was lower than in Control Group. There were no differences in laboratorial data, except for higher glycemia, serum alkaline phosfatase and C-reactive protein in PD Group. There was no difference in the various parameters evaluated when the Subgroups (PPPD and SPD) were compared. CONCLUSION: For long-term pancreaticoduodenectomy, the gastrointestinal symptoms are minimal and the patients had the clinical and nutritional status preserved, regardless of pylorus preservation.

Prevalence of metabolic syndrome in elderly Japanese-Brazilians

Background: Prevalence of individuals with a high cardiovascular risk is elevated in elderly populations. Although metabolic syndrome (MS) increases cardiovascular risk, information is scarce on the prevalence of MS in the elderly. In this study we assessed MS prevalence in a population of elderly Japanese-Brazilians using different MS definitions according to waist circumference cutoff values. Material/Methods: We studied 339 elderly subjects, 44.8% males, aged between 60 to 88 years (70.1 +/- 6.8). MS was defined according to criteria proposed by the Joint Interim Statement in 2009. As waist circumference cutoff point values remain controversial for Asian and Japanese populations, we employed 3 different cutoffs that are commonly used in Japanese epidemiological studies: 1) >90 cm for men and >80 cm for women; 2) >85 cm for men and >90 cm for women; 3) >85 cm for men and >80 cm for women. Results: MS prevalence ranged from 59.9% to 65.8% according to the different definitions. We observed 90% concordance and no statistical difference (p>0.05) in MS prevalence between the 3 definitions. MS diagnosis according to all 3 cutoff values was found in 55.8% of our population, while in only 34.2% was MS discarded by all cutoffs. The prevalence of altered MS components was as follows: arterial blood pressure 82%, fasting glycemia 65.8%, triglyceride 43.4%, and HDL-C levels 36.9%. Conclusions: Elderly Japanese-Brazilians present high metabolic syndrome prevalence independent of waist circumference cutoff values. Concordance between the 3 definitions is high, suggesting that all 3 cutoff values yield similar metabolic syndrome prevalence values in this population.

Exercise training prevents diastolic dysfunction induced by metabolic syndrome in rats

OBJECTIVE: High fructose consumption contributes to the incidence of metabolic syndrome and, consequently, to cardiovascular outcomes. We investigated whether exercise training prevents high fructose diet-induced metabolic and cardiac morphofunctional alterations. METHODS: Wistar rats receiving fructose overload (F) in drinking water (100 g/l) were concomitantly trained on a treadmill (FT) for 10 weeks or kept sedentary. These rats were compared with a control group (C). Obesity was evaluated by the Lee index, and glycemia and insulin tolerance tests constituted the metabolic evaluation. Blood pressure was measured directly (Windaq, 2 kHz), and echocardiography was performed to determine left ventricular morphology and function. Statistical significance was determined by one-way ANOVA, with significance set at p<0.05. RESULTS: Fructose overload induced a metabolic syndrome state, as confirmed by insulin resistance (F: 3.6 +/- 0.2 vs. C: 4.5 +/- 0.2 mg/dl/min), hypertension (mean blood pressure, F: 118 +/- 3 vs. C: 104 +/- 4 mmHg) and obesity (F: 0.31 +/- 0.001 vs. C: 0.29 +/- 0.001 g/mm). Interestingly, fructose overload rats also exhibited diastolic dysfunction. Exercise training performed during the period of high fructose intake eliminated all of these derangements. The improvements in metabolic parameters were correlated with the maintenance of diastolic function. CONCLUSION: The role of exercise training in the prevention of metabolic and hemodynamic parameter alterations is of great importance in decreasing the cardiac morbidity and mortality related to metabolic syndrome.

Glucose Control in Acute Myocardial Infarction: A Pilot Randomized Study Controlled by Continuous Glucose Monitoring System Comparing the Use of Insulin Glargine with Standard of Care

Background: This pilot study aimed to verify if glycemic control can be achieved in type 2 diabetes patients after acute myocardial infarction (AMI), using insulin glargine (iGlar) associated with regular insulin (iReg), compared with the standard intensive care unit protocol, which uses continuous insulin intravenous delivery followed by NPH insulin and iReg (St. Care). Patients and Methods: Patients (n = 20) within 24 h of AMI were randomized to iGlar or St. Care. Therapy was guided exclusively by capillary blood glucose (CBG), but glucometric parameters were also analyzed by blinded continuous glucose monitoring system (CGMS). Results: Mean glycemia was 141 +/- 39 mg/dL for St. Care and 132 +/- 42 mg/dL for iGlar by CBG or 138 +/- 35 mg/dL for St. Care and 129 +/- 34 mg/dL for iGlar by CGMS. Percentage of time in range (80-180 mg/dL) by CGMS was 73 +/- 18% for iGlar and 77 +/- 11% for St. Care. No severe hypoglycemia (<= 40 mg/dL) was detected by CBG, but CGMS indicated 11 (St. Care) and seven (iGlar) excursions in four subjects from each group, mostly in sulfonylurea users (six of eight patients). Conclusions: This pilot study suggests that equivalent glycemic control without increase in severe hyperglycemia may be achieved using iGlar with background iReg. Data outputs were controlled by both CBG and CGMS measurements in a real-life setting to ensure reliability. Based on CGMS measurements, there were significant numbers of glycemic excursions outside of the target range. However, this was not detected by CBG. In addition, the data indicate that previous use of sulfonylurea may be a potential major risk factor for severe hypoglycemia irrespective of the type of insulin treatment.

Role of glycated hemoglobin in the care of diabetes mellitus

Introduction: Persistently high glycemic levels are extremely harmful to the organism and can lead patients to several complications of diabetes mellitus. Glycated hemoglobin represents the glycemic levels for what patient is chronically exposed. Methods: Two virtual databases were surveyed in two languages: Portuguese and English. 12 articles were selected and reviewed. Results and discussion: The HbA1c is used since 1958 in the assessment of glycemic control in diabetic patients. It is formed by a chemical reaction between hemoglobin A and acarbohydrate. Each percentage point of glycated hemoglobin represents approximately 35mg/dL in patient's averageglycemia. Conclusion: The glycated hemoglobin should be measured at least twice per year in patients with diabetes in general. In case of change of hypoglycemic therapy, this frequency should be doubled.

Repression of Ppargc1a Gene in Liver of Hyperglycemic Rats Induced with High Fat Diet Combined with Streptozotocin

Type 2 diabetes mellitus implies deregulation of multiple metabolic processes, being the maintenance of glycemia one of the most important. Many genes are involved in the deregulation of this particular process. Therefore, the aim of this study was to evaluate gene expression of genes related to type 2 diabetes mellitus, in the liver and pancreas of rats with hyperglycemia induced by high fat diet along with a low single dose of streptozotocin. Ahsg and Ppargc1a genes were studied in liver, whereas Kcnj11 and Slc2a2 genes were analyzed in pancreas. For this purpose, 210-240 g female rats were fed a high fat diet or a control diet for three weeks. At day 14, animals fed with high fat diet were injected with a single low dose of streptozotocin (35 mg/kg) and the control group rats were injected only with the vehicle. Plasmatic glucose, triglycerides and total cholesterol levels were measured at the beginning, day 14 and end of treatment. Body weight was also measured. Once the treatment was complete, rats were appropriately euthanized and then, pancreas and liver were surgically removed and frozen in liquid nitrogen. Total RNA was isolated using TRIzol reagent, treated with DNase land reversely transcribed to cDNA. Gene expression analysis was performed using SYBR Green - Real time PCR and comparative Cq method, using three reference genes. Rats fed with high fat diet and treated with streptozotocin showed higher values of plasmatic glucose (17.09 +/- 0.43 vs. 5.91 +/- 0.29 mmol/L, p < 0.01) and a minor expression of Ppargc1a versus the control group (2-fold less expressed, p < 0.05) in liver. We conclude that repression of Ppargc1a gene may be an important process in the establishment of chronic hyperglycemia, probably through deregulation of hepatic gluconeogenesis. However, further studies need to be performed in order to clarify the role of Ppargc1a deregulation in liver glucose homeostasis.
