Estudo comparativo entre cinco diferentes tratamentos sobre as alterações clínicas e laboratoriais do rato diabético induzido pela aloxana

OBJETIVOS: Este estudo visa a analisar os efeitos, a longo prazo, de cinco diferentes tratamentos sobre o controle metabólico de ratos diabéticos aloxânicos. MÉTODOS: Foram analisados 7 grupos experimentais, com 50 ratos cada um, sendo: GN o grupo controle normal; GD o grupo controle diabético, sem tratamento; GI, GA e GIA os grupos tratados, respectivamente, com insulina, acarbose e associação insulina + acarbose; GTIL o grupo tratado com transplante de ilhotas de Langerhans; e o GTPD o grupo tratado com transplante pancreatoduodenal heterotópico. Parâmetros clínicos (peso, ingestão hídrica, ingestão alimentar e diurese) e laboratoriais (glicemia, glicose urinária e insulina plasmática) foram avaliados em todos os animais, no início do experimento, e após 1, 3, 6, 9 e 12 meses de seguimento. RESULTADOS: À exceção do GN, mortalidade foi observada em todos os grupos experimentais no seguimento de 12 meses (GD= 50%; GI= 20%; GA= 26%; GIA= 18%; GTIL= 4%; GTPD= 20%). em GD, GI, GA e GIA os óbitos ocorreram por distúrbios metabólicos ou hidroeletrolíticos e/ou pneumonia, diarréia e caquexia; em GTIL e GTPD todos os óbitos ocorreram por falhas técnicas no pós-operatório até 72h. Animais dos grupos GI, GA e GIA tiveram melhora significativa (p < 0,05) de todos os parâmetros clínicos e laboratoriais observados em ratos diabéticos, sem diferença de efetividade entre os tratamentos. Porém, os resultados observados nestes grupos, biologicamente não foram comparáveis aos observados em GTIL e GTPD, onde observou-se correção completa, aos níveis normais, de todas as variáveis analisadas (p<0,01). CONCLUSÕES: Os tratamentos convencionais com insulina, acarbose e insulina + acarbose melhoraram o estado diabético grave dos ratos tratados, contudo, a eficácia dos tratamentos foi significativamente inferior à oferecida pelo GTIL e GTPD.

Anestesia total intravenosa (ATI) para herniorrafias umbilicais em bezerros

The total intravenous anesthesia (TIVA) is an option for some surgeries in bovines for fields. The aim of this study was to evaluate blood gases effects, cardiorespiratory and glycemia on calves submitted the umbilical herniorraphy. We used eight calves aged from 9 ± 4 months, weighting 111 ± 43 kg. The animals were pre-treated with xylazine (0.05 mg/kg IV) and after 15 minutes was administered ketamine (2.0 mg/kg IV) followed by the continuous infusion of xylazine (0.05 mg/ml), guaifenesin (50 mg/mL) and ketamine (1mg/ml) at a rate of infusion of 2mL/kg/hour. The blood gases and glucose samples were collected immediately before the MPA (MB) and the 5, 40 and 80 after the starting of TIVA (M5, M40 e M80). The other variables were measured in MB, 15 minutes after the MPA (Mx) and every 10 minutes after the starting of TIVA, entiring 80 minutes. The heart rate was higher in MB than in the other stages (p <0.05) and respiratory rate increased in M20 and M50 compared to MB and Mx (p <0.05). The PvCO2 increased while PaO2 decreased in M40 and M80, for MB (p <0.05), PVCO2 in M80 was lower than in MB (p <0.05). The pHv was smaller in M80 than M5 and MB (p <0.05), and HCO3 was lower in MB (p <0.05) compared to the others. The glucose was higher in M40 and M80 and M5 for MB (p <0.05). The recovery time was 152 ± 60 minutes after the end of the administration of the infusion of anesthetics. It was conclude that the anesthetic technique employed promoted respiratory depression, increased blood glucose and prolonged period of anesthetic recovery in calves.

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.

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.

Estilo de vida e saúde de um grupo de idosos de Franca, SP

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.

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.
