Implementation of physiotherapeutic shares in the prevention of diabetes complications in a Family Health Strategy

Introduction In the Family Health Strategy (FHS), the treatment of Diabetes Mellitus (DM) includes education and lifestyle change strategies. Physiotherapists have a key role in this health setting. Objectives To implement actions of evaluation and guidelines for patients with type 2 DM who attend a Family Health Strategy (FHS), regarding diabetic foot and the practice of regular physical exercise in the control and prevention of the complications of Diabetes Mellitus. Methods 17 individuals from an FHS were evaluated, with the following procedures: clinical and anthropometric parameters, inspection, a questionnaire on diabetic neuropathy, tests of vibratory and tactile sensitivity, muscle function, range of motion, functional analysis, questions about exercise practice and guidance regarding controlling blood glucose and foot care. Results Deformities, dry skin, calluses, dehydration, ulceration, cracking and brittle nails were found. Peripheral neuropathy was not observed; tactile sensitivity was altered in the heel region and the vibratory sense was absent in 5% of individuals. A decrease in functionality of ankle movements was verified. Of the participants, 76% were sedentary, 24% knew about the benefits of practicing regular exercise, 25% had undergone a medical evaluation prior to performing physical exercise and, of these, 25% were supervised by a qualified professional. Discussion The implementation of physiotherapy actions in diabetics from an FHS was important for highlighting the presence of risk factors for diabetic complications. Conclusions Individuals attending the FHS need more information and programs for the prevention of diabetic complications.

Diabetes triggers the loss of tooth structure associated to radiographical and histological dental changes and its evolution to progressive pulp and periapical lesions in rats

The aim of this study was to evaluate the putative influence of diabetes without metabolic control in the loss of tooth structure as well as histological changes in dentin and pulp tissue in rats. Diabetes was induced in Wistar rats (n=25) by intravenous administration of alloxan (42mg/kg). Diabetic and non-diabetic control rats were evaluated at 1, 3, 6, 9 and 12 months of follow-up. In order to evaluate the presence and progression of dental caries and periapical lesions, hemimandibles were removed and submitted to radiographical, histological, and morphometrical procedures. Dental caries were detected after radiographical and histological evaluations in diabetic group from the third month of diabetes onset, increasing gradually in frequency and severity in periods. Diabetic rats dental pulps also presented significant reduction in volume density of collagen fibers and fibroblasts at third month, parallel with a trend towards the increase in inflammatory cells volume density. Diabetic rats presented a generalized pulp tissue necrosis after 6 months of diabetes induction. Moreover, periapical lesions were not detected in control group, while these lesions were observed in all rats after 3, 6, 9, and 12 months of diabetes induction. Uncontrolled diabetes seems to trigger the loss of tooth structure, associated to histological dental changes and mediates its evolution to progressive severe pulp and periapical lesions in rats. Therefore, diabetes may be considered a very important risk factor regarding alterations in dental pulp, development of dental caries, and periapical lesions.

Depression and anxiety in pregnant women with diabetes or mild hyperglycemia

A number of physical and psychological changes that occur during pregnancy can stimulate the development of psychological disorders such as anxiety and depression. The study evaluated psychological aspects related to maternal depression and anxiety in pregnant women with diabetes mellitus or hyperglycemia, contrasting the results with those of non-diabetic pregnant women. In a prospective and longitudinal approach, two questionnaires were applied and validated for use in Brazil, the Beck depression inventory and the State-Trait Anxiety Inventory. The questionnaires were applied to pregnant women at the first prenatal visit or at the time of disease diagnosis (T1) and reapplied at admission for delivery (T2). Regardless of the degree of hyperglycemia, both at first and in the second stage most women had severe anxiety trait. In early pregnancy (T1), however, severe state anxiety was more frequent in women with hyperglycemia than in those from the NG group. Most pregnant women showed moderate state anxiety over their pregnancy, regardless of glycemic status. In early pregnancy, however, severe state anxiety was more prevalent in hyperglycemic women than in those with normal glycemic status. Most women showed moderate trait anxiety and mild depression in both early and late pregnancy, irrespective of glycemic status. The incidence of severe state anxiety in early pregnancy is more frequent in women with diabetes or hyperglycemia, but their levels of trait anxiety and depression are not affected by glycemic status.

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.

In vitro antifungal susceptibility of candida albicans isolates from patients with chronic periodontitis and diabetes

Alterations that lead to deficiency of the immune system, such as diabetes mellitus, may promote proliferation of Candida albicans and selection of strains which have greater ability to adhere and to penetrate the host tissues. Recent studies indicate an increase of the antifungal resistance of C. albicans isolates in periodontal pockets, suggesting that the oral cavity could be a reservoir of resistant yeast to antifungal agents. Moreover, oral cavity can act as a reservoir of certain pathogens that may cause systemic infections. The periodontal pocket is an ecological niche suitable to host microorganisms that could act as opportunistic pathogens. The aim of this study is to contribute to the understanding of resistance to conventional antifungal against C. albicans isolates from patients with periodontitis and diabetes. The determination of the minimal inhibitory concentrations (MIC) was evaluated according to M27S3 of the CLSI (2008), with modifications. The results showed that 48.8% of the studied strains were resistant to one or more antifungals and 6.6% were resistant to fluconazole and voriconazole. These results suggest an increasing resistance to conventional antifungal agents among Candida species, suggesting that the oral cavity could host pathogen fungi.

Behavioral risk factors and effects of lifestyle modification on adults with diabetes: a Brazilian community-based study

Lifestyle is directly related to the incidence of type 2 diabetes mellitus (DM-2), a risk dramatically elevated by obesity and inactivity. Several studies have verified that educational interventions can delay the onset of DM-2. Some of the interventions strategies utilized medication and diet, diet and/or physical exercise or the combination of diet and exercise, generally referred to a change in lifestyle. Despite the evidence that DM-2 can be preventive, there is still limited availability of effective prevention programs. DM-2 is considered an emerging public health problem as it is estimated that by the year of 2030 there will be about 366 million people with diabetes worldwide. DM2 remains a leading cause of cardiovascular disorders and many other complications. Our intent with this paper is to present researches and strategies (diet and physical activity interventions) that successfully improved plasma glucose control as a result of an effective lifestyle intervention program.

Color vision impairment in type 2 diabetes assessed by the D-15d test and the Cambridge Colour Test

Color vision impairment emerges at early stages of diabetes mellitus type 2 (DM2) and may precede diabetic retinopathy or the appearance of vascular alterations in the retina. The aim of the present study was to compare the evaluation of the color vision with two different tests - the Lanthony desaturated D-15d test (a traditional color arrangement test), and the Cambridge Colour Test (CCT) (a computerized color discrimination test) - in patients diagnosed with DM2 without clinical signs of diabetic retinopathy (DR), and in sex- and age-matched control groups. Both color tests revealed statistically significant differences between the controls and the worst eyes of the DM2 patients. In addition, the degree of color vision impairment diagnosed by both tests correlated with the disease duration. The D-15d outcomes indicated solely tritan losses. In comparison, CCT outcomes revealed diffuse losses in color discrimination: 13.3% for best eyes and 29% for worst eyes. In addition, elevation of tritan thresholds in the DM2 patients, as detected by the Trivector subtest of the CCT, was found to correlate with the level of glycated hemoglobin. Outcomes of both tests confirm that subclinical losses of color vision are present in DM2 patients at an early stage of the disease, prior to signs of retinopathy. Considering the advantages of the CCT test compared to the D-15d test, further studies should attempt to verify and/or improve the efficiency of the CCT test.

Elderly Individuals with Diabetes: Adding Cognitive Training to Psychoeducational Intervention

The present research examined the effects of a cognitive training program combined with psychoeducational intervention for diabetic elderly patients. Specifically, it aimed at assessing the effects of an eight-session cognitive training and educational program in diabetic elderly individuals and investigating changes in their awareness about specific aspects of diabetes. The final sample consisted of 34 individuals-19 in the experimental group (EG) and 15 in the control group (CG), all residing in the eastern region of the city of Sao Paulo. The protocol included clinical and sociodemographic questions; the Diabetes Attitudes Questionnaire (ATT-19); Diabetes Knowledge Scale (DKN-A); Mini Mental State Examination (MMSE); Verbal Fluency-animal category (VF); Geriatric Depression Scale (GDS); Short Cognitive Performance Test (SKT); and the Rivermead Behavioral Memory Test (RBMT). Results pointed to a significant difference between the two groups for the ATT-19, DKN, and SKT-memory and SKT-total, and a marginally significant difference for the RBMT history in the posttest. As for the remaining cognitive variables, no changes were observed. Retest effects were not observed in the CG. We concluded that cognitive training combined with psychoeducational intervention in diabetic elderly individuals may be effective in producing cognitive gains as well as attitude and knowledge improvement concerning diabetes mellitus (DM).

Prevalence of adults with type 1 diabetes who meet the goals of care in daily clinical practice: A nationwide multicenter study in Brazil

Objective: To determine the prevalence of patients with type 1 diabetes mellitus who meet the glycemic and cardiovascular (CV) risk factors goals and the frequency of screening for diabetic complications in Brazil according to the American Diabetes Association guidelines. Research design and methods: This was a cross-sectional, multicenter study conducted between December 2008 and December 2010 in 28 public clinics in 20 Brazilian cities. Data were obtained from 1774 adult patients (56.8% females, 57.2% Caucasians) aged 30.3 +/- 9.8 years with diabetes duration of 14.3 +/- 8.8 years. Results: Systolic blood pressure was at goal in 40.3% and diastolic blood pressure was at goal in 26.6% of hypertensive patients. LDL cholesterol and HbA1c were at the goal in 45.2% and 13.2% of the patients, respectively. Overweight was presented in 25.6% and obesity in 6.9%. Among those with more than 5 years of disease, screening for retinopathy was performed in the preceding year in 70.1%. Nephropathy and feet complications were screened in 63.1% and 65.1%, respectively. Conclusions: The majority of patients did not meet metabolic control goals and a substantial proportion was not screened for diabetic complications. These issues may increase the risk of chronic complications and negatively impact public health. (C) 2012 Elsevier Ireland Ltd. All rights reserved.

Surgical Treatment of Type 2 Diabetes in Patients with BMI Below 35: Mid-term Outcomes of the Laparoscopic Ileal Interposition Associated with a Sleeve Gastrectomy in 202 Consecutive Cases

The objective of this study was to evaluate the mid-term outcomes of the laparoscopic ileal interposition into the jejunum (JII-SG) or into the duodenum (DII-SG) associated with sleeve gastrectomy for type 2 diabetes mellitus (T2DM) patients with BMI below 35. The procedures were performed on 202 consecutive patients. Mean age was 52.2 +/- 7.5. Mean duration of T2DM was 9.8 +/- 5.2 years. Insulin therapy was used by 41.1%. Dyslipidemia was observed in 78.2%, hypertension in 67.3%, nephropathy in 49.5%, retinopathy in 31.2%, coronary heart disease in 11.9%, and other cardiovascular events in 12.9%. Mean follow-up was 39.1 months (range, 25-61). Early and late mortality was 0.99% and 1.0%, respectively. Early reoperation was performed in 2.5%. Early and late major complications were 8.4% and 3.5%. Early most frequent complications were pneumonia and ileus. Intestinal obstruction was diagnosed in 1.5%. Mean BMI decreased from 29.7 to 23.5 kg/m(2), mean fasting glucose from 202.1 to 112.2 mg/dl, and mean postprandial glucose from 263.3 to 130 mg/dl. Triglycerides diminished from a mean of 273.4 to 110.3 mg/dl and cholesterol from a mean of 204.7 to 160.1 mg/dl. Hypertension was resolved in 87.5%. Mean hemoglobin A(1c) (HbA(1c)) decreased from 8.7 to 6.2% after the JII-SG and to 5.9% following the DII-SG. HbA(1c) below 7% was seen in 89.9% of the patients and below 6.5% in 78.3%. Overall, 86.4% of patients were off antidiabetic medications. Both JII-SG and DII-SG demonstrated to be safe, effective, and long-lasting alternatives for the treatment of T2DM patients with BMI < 35. Beyond glycemic control, other benefits were achieved.

Metabolic profile of patients with diabetes in Barbalha, Brazil

Introduction: Modern life has imposed to people sedentary habits and excessive food consumption, what results into an increase of the incidence of metabolic diseases, which promote the development of atherosclerosis. Objectives: We aimed to evaluate the metabolic profile of diabetic patients assisted by the endocrinology service from Ceara Federal University, located in Barbalha, Brazil. Methods: This is a transversal and retrospective study, based on the analysis of patient records. 119 records were reviewed and 35 of them were selected, according to their registers about anthropometric and laboratorial measuring. Results and discussion: Among the selected records, 65.71% were female patients. It was observed a positive relationship between age and the level of triglycerides, between LDL-cholesterol and the use of tobacco and between blood glucose and glycated hemoglobin. Conclusion: The superposition of risk factor in this group shows the necessity of an integrated assistance and a follow-up about their metabolic profile, aiming to mitigate or retard serious circulatory pathologies.

Previous Exercise Training Has a Beneficial Effect on Renal and Cardiovascular Function in a Model of Diabetes

Exercise training (ET) is an important intervention for chronic diseases such as diabetes mellitus (DM). However, it is not known whether previous exercise training intervention alters the physiological and medical complications of these diseases. We investigated the effects of previous ET on the progression of renal disease and cardiovascular autonomic control in rats with streptozotocin (STZ)-induced DM. Male Wistar rats were divided into five groups. All groups were followed for 15 weeks. Trained control and trained diabetic rats underwent 10 weeks of exercise training, whereas previously trained diabetic rats underwent 14 weeks of exercise training. Renal function, proteinuria, renal sympathetic nerve activity (RSNA) and the echocardiographic parameters autonomic modulation and baroreflex sensitivity (BRS) were evaluated. In the previously trained group, the urinary albumin/creatinine ratio was reduced compared with the sedentary diabetic and trained diabetic groups (p < 0.05). Additionally, RSNA was normalized in the trained diabetic and previously trained diabetic animals (p < 0.05). The ejection fraction was increased in the previously trained diabetic animals compared with the diabetic and trained diabetic groups (p < 0.05), and the myocardial performance index was improved in the previously trained diabetic group compared with the diabetic and trained diabetic groups (p < 0.05). In addition, the previously trained rats had improved heart rate variability and BRS in the tachycardic response and bradycardic response in relation to the diabetic group (p < 0.05). This study demonstrates that previous ET improves the functional damage that affects DM. Additionally, our findings suggest that the development of renal and cardiac dysfunction can be minimized by 4 weeks of ET before the induction of DM by STZ.
