    The incidence of type 2 diabetes can be reduced substantially by implementing preventive measures in high-risk individuals, but this requires prior knowledge of disease risk in the individual. Various diabetes risk models have been designed, and these have all included a similar combination of factors, such as age, sex, obesity, hypertension, lifestyle factors, family history of diabetes and metabolic traits. The accuracy of prediction models is often assessed by the area under the receiver operating characteristic curve (AROC) as a measure of discrimination, but AROCs should be complemented by measures of calibration and reclassification to estimate the incremental value of novel biomarkers. This review discusses the potential of novel biomarkers to improve model accuracy. The range of molecules that serve as potential predictors of type 2 diabetes includes genetic variants, RNA transcripts, peptides and proteins, lipids and small metabolites. Some of these biomarkers lead to a statistically significant increase of model accuracy, but their incremental value currently seems too small for routine clinical use. However, only a fraction of potentially relevant biomarkers have been assessed with regard to their predictive value. Moreover, serial measurements of biomarkers may help determine individual risk. In conclusion, current risk models provide valuable tools of risk estimation, but perform suboptimally in the prediction of individual diabetes risk. Novel biomarkers still fail to have a clinically applicable impact. However, more efficient use of biomarker data and technological advances in their measurement in clinical settings may allow the development of more accurate predictive models in the future.

    Objectives: The objective was to determine the balance impairments and to compare task oriented versus traditional balance training in fall reduction among diabetic patients. Methods: The randomized control trial with descriptive survey and 196 diabetic patients were recruited to assess balance impairments through purposive sampling technique. Eighteen patients were randomly allocated into two groups; task oriented balance training group TOB (n=8) and traditional balance training group TBT (n=10). The inclusion criteria were 30-50 years age bracket and diagnosed cases of Diabetes Mellitus with neuropathy. The demographics were taken through standardized & valid assessment tools include Berg Balance Scale and Functional Reach Test. The measurements were obtained at baseline, after 04 and 08 weeks of training. Results: The mean age of the participants was 49 ±6.79. The result shows that 165(84%) were at moderate risk of fall and 31(15%) were at mild risk of fall among total 196 diabetic patients. There was significant improvement (p <0.05) in task oriented balance training group for dynamic balance, anticipatory balance and reactive balance after 8 weeks of training as compare to traditional balance training. Conclusion: Task oriented balance training is effective in improving the dynamic, anticipator and reactive balance. The task oriented training reduces the risk of falling through enhancing balance outcome. PMID:27648053

    Exercise is considered a cornerstone in the prevention and treatment of type 2 diabetes, but few individuals with type 2 diabetes exercise according to guidelines. We investigated the effect of two time efficient high intensity exercise interventions on exercise capacity, glycemic control and other cardiometabolic risk factors in patients with type 2 diabetes. Twenty-one individuals with type 2 diabetes were randomly assigned to low volume high intensity interval exercise (HIIE; 27 minutes/bout; 10x1-minute at 90 % of HRmax; n = 10) or extremely low volume sprint interval exercise (SIE; 10 minutes/bout; 2x20 seconds at maximum achievable intensity; n = 11) 3 days/week for 12 weeks. Aerobic exercise capacity (VO2peak), glycosylated hemoglobin (HbA1c), blood pressure and body composition were measured at baseline and post test. Both HIIE and SIE improved VO2peak (3.3 mL·min-1·kg-1, 10.4 %), p < 0.01, and 1.4 mL·min-1·kg-1 (4.6 %), p = 0.03, respectively). Only HIIE reduced body fat percentage (4.5 %, p = 0.04) and two minute heart rate recovery (11.0 bpm, p = 0.02). Neither HIIE nor SIE improved HbA1c. In conclusion, this study indicates that substantially lower exercise volumes than recommended in current guidelines can improve aerobic exercise capacity in individuals with type 2 diabetes. However, 12 weeks of time efficient high intensity exercise did not improve glycemic control, and interventions of longer duration should be investigated. Key points Low volume high-intensity interval exercise can improve peak oxygen uptake in previously sedentary individuals with type 2 diabetes The weekly exercise volumes in the two intervention groups of 81 and 30 minutes respectively, is substantially lower than recommended in current exercise guidelines and could reduce the time-barrier associated with exercise among patients with type 2 diabetes. However, 12 weeks of structured, supervised low-volume exercise did not improve glycemic control, indicating a need for

    Background In low/middle income countries like India, diabetes is prevalent and health care access limited. Most adults have a mobile phone, creating potential for mHealth interventions to improve public health. To examine the feasibility and initial evidence of effectiveness of mDiabetes, a text messaging program to improve diabetes risk behaviors, a global nonprofit organization (Arogya World) implemented mDiabetes among one million Indian adults. Objective A prospective, parallel cohort design was applied to examine whether mDiabetes improved fruit, vegetable, and fat intakes and exercise. Methods Intervention participants were randomly selected from the one million Nokia subscribers who elected to opt in to mDiabetes. Control group participants were randomly selected from non-Nokia mobile phone subscribers. mDiabetes participants received 56 text messages in their choice of 12 languages over 6 months; control participants received no contact. Messages were designed to motivate improvement in diabetes risk behaviors and increase awareness about the causes and complications of diabetes. Participant health behaviors (exercise and fruit, vegetable, and fat intake) were assessed between 2012 and 2013 via telephone surveys by blinded assessors at baseline and 6 months later. Data were cleaned and analyzed in 2014 and 2015. Results 982 participants in the intervention group and 943 in the control group consented to take the phone survey at baselne. At the end of the 6-month period, 611 (62.22%) in the intervention and 632 (67.02%) in the control group completed the follow-up telephone survey. Participants receiving texts demonstrated greater improvement in a health behavior composite score over 6 months, compared with those who received no messages F(1, 1238) = 30.181, P<.001, 95% CI, 0.251-0.531. Fewer intervention participants demonstrated health behavior decline compared with controls. Improved fruit, vegetable, and fat consumption (P<.01) but not exercise were

    Background A limited number of studies have assessed the risk of common diseases when combining information from several predisposing polymorphisms. In most cases, individual polymorphisms only moderately increase risk (~20%), and they are thought to be unhelpful in assessing individuals' risk clinically. The value of analyzing multiple alleles simultaneously is not well studied. This is often because, for any given disease, very few common risk alleles have been confirmed. Methods and Findings Three common variants (Lys23 of KCNJ11, Pro12 of PPARG, and the T allele at rs7903146 of TCF7L2) have been shown to predispose to type 2 diabetes mellitus across many large studies. Risk allele frequencies ranged from 0.30 to 0.88 in controls. To assess the combined effect of multiple susceptibility alleles, we genotyped these variants in a large case-control study (3,668 controls versus 2,409 cases). Individual allele odds ratios (ORs) ranged from 1.14 (95% confidence interval [CI], 1.05 to 1.23) to 1.48 (95% CI, 1.36 to 1.60). We found no evidence of gene-gene interaction, and the risks of multiple alleles were consistent with a multiplicative model. Each additional risk allele increased the odds of type 2 diabetes by 1.28 (95% CI, 1.21 to 1.35) times. Participants with all six risk alleles had an OR of 5.71 (95% CI, 1.15 to 28.3) compared to those with no risk alleles. The 8.1% of participants that were double-homozygous for the risk alleles at TCF7L2 and Pro12Ala had an OR of 3.16 (95% CI, 2.22 to 4.50), compared to 4.3% with no TCF7L2 risk alleles and either no or one Glu23Lys or Pro12Ala risk alleles. Conclusions Combining information from several known common risk polymorphisms allows the identification of population subgroups with markedly differing risks of developing type 2 diabetes compared to those obtained using single polymorphisms. This approach may have a role in future preventative measures for common, polygenic diseases. PMID:17020404

    Abnormally elevated postprandial glucose and triacylglycerol (TAG) concentrations are risk factors for cardiovascular disease in type 2 diabetes. The most effective time to exercise to lower postprandial glucose and TAG concentrations is unknown. Thus the aim of this study was to determine what time is more effective, either pre- or postdinner resistance exercise (RE), at improving postprandial risk factors in patients with type 2 diabetes. Thirteen obese patients with type 2 diabetes completed three trials in a random order in which they consumed a dinner meal with 1) no RE (NoRE), 2) predinner RE (RE → M), and 3) postdinner RE beginning 45 min after dinner (M → RE). Clinical outcome measures included postprandial glucose and TAG concentrations. In addition, postprandial acetaminophen (gastric emptying), endocrine responses, free fatty acids, and β-cell function (mathematical modeling) were measured to determine whether these factors were related to changes in glucose and TAG. The TAG incremental area under the curve (iAUC) was ∼92% lower (P ≤ 0.02) during M → RE compared with NoRE and RE → M, an effect due in part to lower very-low-density lipoprotein-1 TAG concentrations. The glucose iAUC was reduced (P = 0.02) by ∼18 and 30% during the RE → M and M → RE trials, respectively, compared with NoRE, with no difference between RE trials. RE → M and M → RE reduced the insulin iAUC by 35 and 48%, respectively, compared with NoRE (P < 0.01). The glucagon-like peptide-1 iAUC was ∼50% lower (P ≤ 0.02) during M → RE compared with NoRE and RE → M. Given that predinner RE only improves postprandial glucose concentrations, whereas postdinner RE improves both postprandial glucose and TAG concentrations, postdinner RE may lower the risk of cardiovascular disease more effectively.

    Objective: The purpose of this analysis is to examine the effect of an algorithm-driven online diabetes prevention program on changes in eating habits, physical activity and wellness/productivity factors. Methods: The intervention, Alive-PD, used small-step individually tailored goal setting and other features to promote changes in diet and physical activity. A 6-month randomized controlled trial was conducted among patients from a healthcare delivery system who had confirmed prediabetes (n =339). Change in weight and glycemic markers were measured in the clinic. Changes in physical activity, diet and wellness/productivity factors were self-reported. Mean age was 55 (s.d. 8.9) years, mean body mass index was 31 (s.d. 4.4) kg m−2, 68% were white and 69% were male. Results: The intervention group increased fruit/vegetable consumption by 3.71 (95% confidence interval (CI) 2.73, 4.70) times per week (effect size 0.62), and decreased refined carbohydrates by 3.77 (95% CI 3.10, 4.44) times per week both significantly (P<0.001) greater changes than in the control group. The intervention group also reported a significantly greater increase in physical activity than in the control group, effect size 0.49, P<0.001. In addition, the intervention group reported a significant increase in self-rated health, in confidence in ability to make dietary changes and in ability to accomplish tasks, and a decrease in fatigue, compared with the control group. These changes paralleled the significant treatment effects on glycemic markers and weight. Conclusions: In addition to promoting improvements in weight and glycemic markers, the Alive-PD program appears to improve eating habits and physical activity, behaviors important not just for diabetes prevention but for those with diagnosed diabetes or obesity. The improvements in wellness/productivity may derive from the diet and activity improvements, and from the satisfaction and self-efficacy of achieving goals. PMID:27643726

    Background In this study of women with gestational diabetes we attempted to (a) Determine the magnitude of the long term risk of progression to diabetes and (b) Identify factors that predict the development of diabetes. Methods All women diagnosed with gestational diabetes (GDM) at Worcestershire Royal Hospital, UK from 1995 to 2003 were included in this observational cohort study and followed up till 2009. Diabetes was diagnosed if fasting glucose ≥ 7.0 mmol/L, random/two-hour glucose following 75 gram oral glucose test (OGTT) ≥ 11.1 mmol/L or HbA1c ≥ 7.0%. Results The risk of developing diabetes was 6.9% at five years and 21.1% at ten years following the initial diagnosis of GDM. Fasting and post-prandial glucose levels in the oral glucose tolerance test during pregnancy were associated with future risk of diabetes. There was no association with age, gestational age at diagnosis of GDM, numbers of previous and subsequent pregnancies. Conclusion Risk of progression to diabetes in a UK based cohort of women with GDM is estimated. Women with fasting antenatal glucose ≥ 7.0 mmol/L and/or an antenatal two-hour glucose ≥ 11.1 mmol/L are at higher risk and need close follow up. PMID:23519363

    Background The EQ-5D was used to compare burden experienced by respondents with diabetes and those at risk for diabetes. Methods A survey including the EQ-5D was mailed to individuals with self-reported diabetes, as well as those without diabetes but with the following risk factors (RFs): (1) abdominal obesity, (2) body mass index ≥ 28 kg/m2, (3) dyslipidemia, (4) hypertension, and (5) cardiovascular disease. Non-diabetes respondents were combined into 0–2 RFs and 3–5 RFs. Mean EQ-5D scores were compared across groups using analysis of variance. Multivariable linear regression modeling identified factors affecting respondents' EQ-5D scores. Results Complete responses were available from >75% of each cohort. Mean EQ-5D index scores were significantly lower for respondents with type 2 diabetes and 3–5 RFs (0.778 and 0.792, respectively) than for those with 0–2 RFs (0.870, p < 0.001 for each); score for respondents with type 2 diabetes was also significantly lower than for those with 3–5 RFs (p < 0.001). Similar patterns were seen for visual analog scale (VAS). For both VAS and index scores, after adjusting for other characteristics, respondents reported decreasing EQ-5D scores as status moved from low to high risk (-6.49 for VAS score and -0.045 for index score) to a diagnosis of type 2 diabetes (-9.75 for VAS score and -0.054 for index score; p < 0.001 vs. 0–2 RFs for all). Conclusion High-risk and type 2 diabetes groups had similar EQ-5D scores, and both were substantially lower than in low-risk respondents. PMID:18304340

    Background It is unclear if achieving multiple risk factor (RF) goals through protocol-guided intensive medical therapy is feasible or improves outcomes in type 2 diabetes (T2DM). Objectives We sought to quantify the relationship between achieved RF goals in the BARI 2D (Bypass Angioplasty Investigation Revascularization 2 Diabetes) trial and cardiovascular events/survival. Methods We performed a nonrandomized analysis of survival/cardiovascular events and control of 6 RFs (nonsmoker, non-HDL-C <130 mg/dl, triglycerides <150 mg/dl, blood pressure [systolic <130 mm Hg; diastolic <80 mm Hg], hemoglobin A1c <7%) in BARI 2D. Cox models with time-varying number of RFs in control were adjusted for baseline number of RFs in control, clinical characteristics, and trial randomization assignments. Results In 2,265 patients (mean age 62 years, 29% women) followed for 5 years, the mean ± SD number of RFs in control improved from 3.5 ± 1.4 out of 6 at baseline to 4.2 ± 1.3 at 5 years, p < 0.0001. The number of RFs in control during the trial was strongly related to death (global p = 0.0010) and the composite of death, myocardial infarction and stroke (global p = 0.0035) in fully adjusted models. Participants with 0 to 2 RFs in control during follow-up had a 2-fold higher risk of death (hazard ratio [HR]: 2.0; 95% CI: 1.3 to 3.3, p = 0.0031) and a 1.7-fold higher risk of the composite endpoint (HR: 1.7; 95% CI 1.2 to 2.5, p = 0.0043), compared with those with 6 RFs in-control. Conclusions Simultaneous control of multiple RFs through protocol-guided intensive medical therapy is feasible and relates to cardiovascular morbidity and mortality in patients with coronary disease and T2DM.

    Scientific and technological advancements have led to the increasing availability and use of sophisticated devices for diabetes management, with corresponding improvements in public health. These devices are often capable of sharing data with a few other specific devices but are generally not broadly interoperable; they cannot work together with a wide variety of other devices. As a result of limited interoperability, benefits of modern diabetes devices and potential for development of innovative new diabetes technologies are not being fully realized. Here we discuss diabetes device interoperability in general, then focus on 4 examples that show how diabetes management could benefit from enhanced interoperability: remote monitoring and data sharing, integrating data from multiple devices to better inform diabetes management strategies, device consolidation, and artificial pancreas development.

    Aims Cardiovascular disease (CVD) is the leading cause of morbidity and mortality in people with diabetes in South Asia. The CARRS translation trial tests the effectiveness, cost-effectiveness, and sustainability of a clinic-based multi-component CVD risk reduction intervention among people with diabetes in India and Pakistan. Methods We randomly assigned 1,146 adults with diabetes recruited from 10 urban clinic sites, to receive usual care by physicians or to receive an integrated multi-component CVD risk reduction intervention. The intervention involves electronic health record management, decision-support prompts to the healthcare team, and the support of a care coordinator to actively facilitate patient and provider adherence to evidence-based guidelines. The primary outcome is a composite of multiple CVD risk factor control (blood glucose and either blood pressure or cholesterol, or all three). Other outcomes include control of the individual CVD risk factors, process and patient-centered measures, cost-effectiveness, and acceptability/feasibility. Conclusion The CARRS translation trial tests a low-cost diabetes care delivery model in urban South Asia to achieve comprehensive cardio-metabolic disease case-management of high-risk patients (clinicaltrials.gov number: NCT01212328).

    Diabetic clients must make daily decisions about their health care needs. Observational and anecdotal evidence suggests that vast differences exist between the kinds of choices diabetic clients make and the kinds of chances they are willing to take. The purpose of this investigation was to develop a diabetic risk-assessment tool. This instrument, which is based on subjective expected utility theory, measures risk-prone and risk-averse behavior. Initial findings from a pilot study of 18 women clients who are on insulin indicate that patterns of risk behavior exist in the areas of exercise, skin care, and diet. PMID:1729123

  16. Diabetic dyslipidaemia: effective management reduces cardiovascular risk.

    Patients with diabetes are at significantly increased risk for coronary heart disease (CHD); even those patients without a history of a previous myocardial infarction (MI) have as high a risk of a fatal or nonfatal MI as nondiabetic patients with a history of previous MI. As a result it is now generally recommended that cardiovascular risk factors be treated as aggressively in patients with diabetes as in nondiabetic patients with a history of CHD. Results from the recently published Collaborative Atorvastatin Diabetes Study (CARDS) and meta-analysis of primary and secondary interventions trials confirm that there is a uniform relative risk reduction across a wide range of high-risk patients including diabetes patients without established CHD. A highly significant 22-24% reduction in risk of future vascular events is evident when patients with diabetes are treated with statins in trials. Current guidelines, including the recently updated National Cholesterol Education Program (NCEP) guidelines, endorse aggressive, early intervention in very-high-risk patients, such as those with diabetes plus cardiovascular disease (CVD), regardless of baseline low-density lipoprotein cholesterol (LDL-C) level in order to achieve an LDL-C goal of 70 mg/dL (1.8 mmol/L). However, despite increasing evidence and knowledge of the value of lipid lowering, a recent survey of diabetes specialists indicates that many patients with diabetes remain untreated or undertreated. The availability of more effective statins should help to close this "action gap", in concert with other measures such as initiatives to improve patient compliance.

    Purpose We examined perceptions of 10-year coronary heart disease (CHD) risk or likelihood of having undiagnosed diabetes or impaired fasting glucose (IFG) with actual risk in a community sample of Hispanic adults. Methods We conducted a survey of 183 Hispanic adults (≥18 years) recruited at community events around Charleston, SC. Likelihood of having undiagnosed diabetes/IFG as well as 10-year CHD risk were calculated. Perceived risk was assessed with questions based on the Risk Perception Survey-Diabetes Mellitus. Results Over half of respondents (54.8%) underestimated their likelihood of undiagnosed diabetes/IFG and 14.8% underestimated their 10-year CHD risk. Older and overweight respondents were more likely to underestimate their likelihood of undiagnosed diabetes/IFG. Respondents with family history of diabetes were the least likely to underestimate their likelihood of current undiagnosed diabetes/IFG. Respondents with diagnosed hypertension, diabetes, high cholesterol or a family history of heart attack were more likely to underestimate their 10-year CHD risk. Men were more likely to underestimate their risk for diabetes/IFG and CHD risk. Conclusions Health education to improve accurate risk perception could improve health promotion for this population.

    PubMed Central

    2013-01-01

    Background Metabolic syndrome is a cluster of cardiovascular risk factors that greatly increase the risk of developing cardiovascular disease and type 2 diabetes. Regular exercise improves the risk profile, but most people do not successfully change their exercise habits to beneficially reduce risk. Tailored exercise prescribed by a family physician has shown promise as a means to increase fitness and reduce cardiometabolic risk, but optimal implementation practices remain unknown. Mobile health technologies have proved to be a beneficial tool to achieve blood pressure and blood glucose control in patients with diabetes. These technologies may address the limited access to health interventions in rural and remote regions. However, the potential as a tool to support exercise-based prevention activities is not well understood. This study was undertaken to investigate the effects of a tailored exercise prescription alone or supported by mobile health technologies to improve metabolic syndrome and related cardiometabolic risk factors in rural community-dwelling adults at risk for cardiovascular disease and type 2 diabetes. Methods/Design Adults (n = 149) with at least two metabolic syndrome risk factors were recruited from rural communities and randomized to either: 1) an intervention group receiving an exercise prescription and devices for monitoring of risk factors with a smartphone data portal equipped with a mobile health application; or 2) an active control group receiving only an exercise prescription. All participants reported to the research centre at baseline, and at 12-, 24- and 52-week follow-up visits for measurement of anthropometrics and blood pressure and for a blood draw to test blood-borne markers of cardiometabolic health. Vascular and autonomic function were examined. Fitness was assessed and exercise prescribed according to the Step Test and Exercise Prescription protocol. Discussion This study tested the effects of a prescriptive exercise

    Objective The study objective was to examine the association between menopause status and diabetes risk among women with glucose intolerance and to determine if menopausal status modifies response to diabetes prevention interventions. Methods The study population included women in premenopause (n=708), natural postmenopause (n=328), and bilateral oophorectomy (n=201) in the Diabetes Prevention Program (DPP), a randomized placebo-controlled trial of lifestyle intervention and metformin among glucose intolerant adults. Associations between menopause and diabetes risk were evaluated using Cox proportional hazard models that adjusted for demographic variables (age, race/ethnicity, family history of diabetes, history of gestational diabetes mellitus), waist circumference, insulin resistance and corrected insulin response. Similar models were constructed after stratification by menopause type and hormone therapy (HT) use. Results After adjustment for age, there was no association between natural menopause or bilateral oophorectomy and diabetes risk. Differences by study arm were observed in women who reported bilateral oophorectomy. In the lifestyle arm, women with bilateral oophorectomy had a lower adjusted hazard for diabetes (HR 0.19, 95% CI 0.04, 0.94), although observations were too few to determine if this was independent of HT use. No significant differences were seen in the metformin (HR 1.29, 95% CI 0.63, 2.64) or placebo arms (HR 1.37, 95% CI 0.74, 2.55). Conclusions Among women at high-risk for diabetes, natural menopause was not associated with diabetes risk and did not affect response to diabetes prevention interventions. In the lifestyle intervention, bilateral oophorectomy was associated with decreased diabetes risk. PMID:21709591

    Diabetic maculopathy is characterised by increased capillary leakage in the main retinal vessels and by alterations in the microcirculation of the macula. Maculopathy occurs frequently in type 1 and type 2 diabetic patients. Prevalence is higher in type 2 than in type 1 diabetic patients. Factors associated with the development of maculopathy are mostly unknown. As maculopathy is the main cause of vision deprivation in diabetic patients it is essential to know the associations and risk factors of diabetic maculopathy so that appropriate measures can be taken to prevent as well as treat diabetic maculopathy. We started the research work to find out the relation between diabetic maculopathy and various associated factors and risk factors for patients with diabetic retinopathy with maculopathy. This cross-sectional observational study done at the Department of Ophthalmology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka & National Institute of Ophthalmology & Hospital (NIO & H), Sher-e-Bangla Nagar, Dhaka, Bangladesh from January 2006 to June 2006. In this study out of 50 patients, diabetes was controlled in 20(40%) patients and uncontrolled in 30(60%). A significant percentage of patients (40%) had elevated blood pressure. Diabetic autonomic neuropathy was observed in 24% cases and polyneuropathy was observed in 36% cases. It is evident that diabetic maculopathy has association with dyslipidaemia, abnormal renal function due to nephropathy. This study lighted on the association of diabetic maculopathy with diabetic nephropathy, cardiac abnormalities and diabetic neuropathy. PMID:27277354

    Type 2 diabetes is a chronic disease that is increasing in prevalence globally. Cardiovascular disease is a major cause of mortality and morbidity in diabetes, and lifestyle and clinical risk factors do not fully account for the link between the conditions. This article provides an overview of the evidence concerning the role of psychosocial stress factors in diabetes risk, as well as in cardiovascular complications in people with existing diabetes. Several types of psychosocial factors are discussed including depression, other types of emotional distress, exposure to stressful conditions, and personality traits. The potential behavioral and biological pathways linking psychosocial factors to diabetes are presented and implications for patient care are highlighted. PMID:27566328

    Purpose: This trial was conducted to evaluate the effects of oligofructose-enriched inulin on some of cardiovascular disease risk factors in women with type 2 diabetes. Methods: 52 females (25diabetes were randomly assigned to two groups. Participants received 10g/d oligofructose-enriched inulin (n=27) or 10g/d placebo (n=25) for 8 weeks. Fasting blood samples were taken to measure metabolic profiles, malondialdehyd and antioxidant enzymes at baseline and after the 8 weeks intervention. Paired, unpaired sample t-test and analysis of covariance were used to comparison of quantitative variables. Results: After 8 weeks, in the oligofructose-enriched inulin group there was a significant increase in total antioxidant capacity (0.2 mmol/l, 20.0%) and a significant decrease in fasting plasma glucose (19.2 mg/dL, 9.4%) HbA1c (0.5%, 8.4%), total cholesterol (TC) (28.0 mg/dL, 14.1%), low-density lipoprotein cholesterol (LDL-c) (22.0 mg/dL, 21.7%), TC/HDL-c ratio (0.73, 20.7%), LDL-c/HDL-c ratio (0.55, 27.5%) and malondialdehyd (1.7 nmol/ml, 39.7%) compared to the placebo group. Changes in concentrations of triglycerides, high-density lipoprotein cholesterol (HDLc), superoxide dismutase, catalase and glutathione peroxidase were not significant in oligofructose-enriched inulin group compared to the placebo group. Conclusion: Oligofructose-enriched inulin may improve glycemic indices, lipid profile, antioxidant status and malondialdehyd in women with type 2 diabetes. PMID:26819923

    In this review, we explore the concept of 'double diabetes', a combination of type 1 diabetes with features of insulin resistance and type 2 diabetes. After considering whether double diabetes is a useful concept, we discuss potential mechanisms of increased insulin resistance in type 1 diabetes before examining the extent to which double diabetes might increase the risk of cardiovascular disease (CVD). We then go on to consider the proposal that weight gain from intensive insulin regimens may be associated with increased CV risk factors in some patients with type 1 diabetes, and explore the complex relationships between weight gain, insulin resistance, glycaemic control and CV outcome. Important comparisons and contrasts between type 1 diabetes and type 2 diabetes are highlighted in terms of hepatic fat, fat partitioning and lipid profile, and how these may differ between type 1 diabetic patients with and without double diabetes. In so doing, we hope this work will stimulate much-needed research in this area and an improvement in clinical practice. PMID:23613085

    Approximately 347 million persons were estimated to have diabetes worldwide in 2008, an increase of 194 million cases from 1980. Diabetes now affects both high- and low-income countries, with low-income countries bearing the majority of the burden. The epidemiologic transition from traditional health risks, such as poor hygiene, to modern health risks, such as sedentary lifestyle, has facilitated the increase in incidence in diabetes, especially in developing countries. The effect of these risk factors may be especially pronounced in some racial and ethnic populations. Increased surveillance for diabetes has contributed to increased diabetes prevalence in higher-income countries. Survival with and some risk factors for diabetes have improved in developed countries, but global diabetes mortality has increased by 20 % since 1990. Population growth and aging will only increase the burden of diabetes, and public health interventions are needed to address diabetes risk factors to stem the tide of this epidemic. PMID:24072478

    Background/objectives A healthy diet is an integral component of successful diabetes management. However, the comparative importance of adopting a healthy diet for cardiovascular risk factor reduction over and above medication use among newly diagnosed diabetes patients remains unclear. Subjects/Methods We computed a dietary score consistent with American Diabetes Association and Diabetes UK recommendations in 574 newly diagnosed diabetes patients by summing standardised values for the intake of total energy, saturated fat, sodium, fibre and plasma vitamin C. In linear regression analyses, stratified by cardio-protective medication use (yes/no), we quantified the comparative longitudinal associations of baseline diet and change in diet over 1-year with change in blood pressure, HbA1c and lipids. Results Baseline diet was generally not predictive of change in cardiovascular risk factor levels at 1-year. In contrast, dietary change over 1-year among patients prescribed and not prescribed cardio-protective medication after baseline was associated with comparative (p-interaction all ≥0.95) reductions in diastolic blood pressure (−2.38 vs. −2.93 mmHg, respectively) and triglycerides (−0.31 vs. −0.21 mmol/l, respectively), independent of potential confounding factors and change from baseline to follow-up in physical activity and smoking status. Conclusions Modest dietary change over the first year following diagnosis of diabetes was associated with reductions in blood pressure and triglycerides, over and above the effects of cardio-protective medication. Our findings support the notion that dietary change should be viewed as an integral component of successful diabetes self-management, irrespective of medication use. PMID:24801371

    Prediabetes, covering individuals with impaired fasting glycemia, impaired glucose tolerance, or high-risk HbA1c levels, is associated with a ∼20 % increased risk of developing cardiovascular disease (CVD) compared with normoglycemic individuals. It is well-known that lifestyle or pharmacologic interventions can prevent diabetes in prediabetic people; however, the evidence is less clear regarding prevention of CVD. Most diabetes prevention trials have failed to show beneficial effects on CVD morbidity and mortality despite significant improvements of CVD risk factors in individuals with prediabetes. Another challenge is how to estimate CVD risk in prediabetic people. In general, prediction models for CVD do not take glucose levels or prediabetes status into account, thereby underestimating CVD risk in these high-risk individuals. More evidence within risk stratification and management of CVD risk in prediabetes is needed in order to recommend useful and effective strategies for early prevention of CVD.

    Type 2 diabetes mellitus (DM) and cancer are common diseases that are frequently diagnosed in the same individual. An association between the two conditions has long been postulated. Here, we review the epidemiological evidence for increased risk of cancer, decreased cancer survival, and decreased rates of cancer screening in diabetic patients. The risk for several cancers, including cancers of the pancreas, liver, colorectum, breast, urinary tract, and endometrium, is increased in patients with DM. In a pooled risk analysis weighting published meta-analytic relative risk (RR) for individual cancer by differences in their incidence rates, we found a population RR of 0.97 (95 % CI, 0.75–1.25) in men and 1.29 (95 % CI, 1.16–1.44) in women. All meta-analyses showed an increased relative risk for cancer in diabetic men, except studies of prostate cancer, in which a protective effect was observed. The relationship between diabetes and cancer appears to be complex, and at present, a clear temporal relationship between the two conditions cannot be defined. DM also impacts negatively on cancer-related survival outcomes and cancer screening rates. The overwhelming evidence for lower cancer screening rates, increased incidence of certain cancers, and poorer prognosis after cancer diagnosis in diabetic patients dictates a need for improved cancer care in diabetic individuals through improved screening measures, development of risk assessment tools, and consideration of cancer prevention strategies in diabetic patients. Part two of this review focuses on the biological and pharmacological mechanisms that may account for the association between DM and cancer. PMID:22552844

    Trials have demonstrated the preventability of type 2 diabetes through lifestyle modifications or drugs in people with impaired glucose tolerance. However, alternative ways of identifying people at risk of developing diabetes are required. Multivariate risk scores have been developed for this purpose. This article examines the evidence for performance of diabetes risk scores in adults by 1) systematically reviewing the literature on available scores and 2) their validation in external populations; and 3) exploring methodological issues surrounding the development, validation, and comparison of risk scores. Risk scores show overall good discriminatory ability in populations for whom they were developed. However, discriminatory performance is more heterogeneous and generally weaker in external populations, which suggests that risk scores may need to be validated within the population in which they are intended to be used. Whether risk scores enable accurate estimation of absolute risk remains unknown; thus, care is needed when using scores to communicate absolute diabetes risk to individuals. Several risk scores predict diabetes risk based on routine noninvasive measures or on data from questionnaires. Biochemical measures, in particular fasting plasma glucose, can improve prediction of such models. On the other hand, usefulness of genetic profiling currently appears limited.

    While lifestyle interventions involving exercise and a healthy diet in high-risk adults have been found to reduce progression to type 2 diabetes by >50%, little attention has been given to the potential benefits of such strategies in women with a history of gestational diabetes mellitus (GDM). We conducted a literature search of PubMed for English language studies of randomized controlled trials of lifestyle interventions among women with a history of GDM. In total, nine studies were identified which fulfilled the eligibility criteria. The majority of randomized trials of lifestyle interventions in women with GDM have been limited to pilot or feasibility studies. However, preliminary findings suggest that such interventions can improve diabetes risk factors in women with a history of GDM. Larger, well-designed controlled randomized trials are needed to assess the effects of lifestyle interventions on preventing subsequent progression to type 2 diabetes among women with GDM.

Design Systematic review using standard (quantitative) and realist (mainly qualitative) methodology. Inclusion criteria Papers in any language describing the development or external validation, or both, of models and scores to predict the risk of an adult developing type 2 diabetes. Data sources Medline, PreMedline, Embase, and Cochrane databases were searched. Included studies were citation tracked in Google Scholar to identify follow-on studies of usability or impact. Data extraction Data were extracted on statistical properties of models, details of internal or external validation, and use of risk scores beyond the studies that developed them. Quantitative data were tabulated to compare model components and statistical properties. Qualitative data were analysed thematically to identify mechanisms by which use of the risk model or score might improve patient outcomes. Results 8864 titles were scanned, 115 full text papers considered, and 43 papers included in the final sample. These described the prospective development or validation, or both, of 145 risk prediction models and scores, 94 of which were studied in detail here. They had been tested on 6.88 million participants followed for up to 28 years. Heterogeneity of primary studies precluded meta-analysis. Some but not all risk models or scores had robust statistical properties (for example, good discrimination and calibration) and had been externally validated on a different population. Genetic markers added nothing to models over clinical and sociodemographic factors. Most authors described their score as “simple” or “easily implemented,” although few were specific about the intended users and under what circumstances. Ten mechanisms were identified by which measuring diabetes risk might improve outcomes. Follow-on studies that applied a risk score as part of an

    Recently, 5 amino acids were identified and verified as important metabolites highly associated with type 2 diabetes (T2D) development. This report aims to assess the association of tryptophan with the development of T2D and to evaluate its performance with existing amino acid markers. A total of 213 participants selected from a ten-year longitudinal Shanghai Diabetes Study (SHDS) were examined in two ways: 1) 51 subjects who developed diabetes and 162 individuals who remained metabolically healthy in 10 years; 2) the same 51 future diabetes and 23 strictly matched ones selected from the 162 healthy individuals. Baseline fasting serum tryptophan concentrations were quantitatively measured using ultra-performance liquid chromatography triple quadruple mass spectrometry. First, serum tryptophan level was found significantly higher in future T2D and was positively and independently associated with diabetes onset risk. Patients with higher tryptophan level tended to present higher degree of insulin resistance and secretion, triglyceride and blood pressure. Second, the prediction potential of tryptophan is non-inferior to the 5 existing amino acids. The predictive performance of the combined score improved after taking tryptophan into account. Our findings unveiled the potential of tryptophan as a new marker associated with diabetes risk in Chinese populations. The addition of tryptophan provided complementary value to the existing amino acid predictors. PMID:27598004

    Foot ulceration remains a serious health concern for diabetic patients and has a major impact on the cost of diabetes treatment. Early detection and preventive care, such as offloading or improved hygiene, can greatly reduce the risk of further complications. We aim to assess the use of hyperspectral tissue oximetry in predicting the risk of diabetic foot ulcer formation. Tissue oximetry measurements are performed during several visits with hyperspectral imaging of the feet in type 1 and 2 diabetes mellitus subjects that are at risk for foot ulceration. The data are retrospectively analyzed at 21 sites that ulcerated during the course of our study and an ulceration prediction index is developed. Then, an image processing algorithm based on this index is implemented. This algorithm is able to predict tissue at risk of ulceration with a sensitivity and specificity of 95 and 80%, respectively, for images taken, on average, 58 days before tissue damage is apparent to the naked eye. Receiver operating characteristic analysis is also performed to give a range of sensitivity/specificity values resulting in a Q-value of 89%.

    2015-01-01

    Obesity and type 2 diabetes are becoming increasingly prevalent worldwide, and both are associated with an increased incidence and mortality from many cancers. The metabolic abnormalities associated with type 2 diabetes develop many years before the onset of diabetes and, therefore, may be contributing to cancer risk before individuals are aware that they are at risk. Multiple factors potentially contribute to the progression of cancer in obesity and type 2 diabetes, including hyperinsulinemia and insulin-like growth factor I, hyperglycemia, dyslipidemia, adipokines and cytokines, and the gut microbiome. These metabolic changes may contribute directly or indirectly to cancer progression. Intentional weight loss may protect against cancer development, and therapies for diabetes may prove to be effective adjuvant agents in reducing cancer progression. In this review we discuss the current epidemiology, basic science, and clinical data that link obesity, diabetes, and cancer and how treating obesity and type 2 diabetes could also reduce cancer risk and improve outcomes.

    Type 1 diabetes is diagnosed at the end of a prodrome of β-cell autoimmunity. The disease is most likely triggered at an early age by autoantibodies primarily directed against insulin or glutamic acid decarboxylase, or both, but rarely against islet antigen-2. After the initial appearance of one of these autoantibody biomarkers, a second, third, or fourth autoantibody against either islet antigen-2 or the ZnT8 transporter might also appear. The larger the number of β-cell autoantibody types, the greater the risk of rapid progression to clinical onset of diabetes. This association does not necessarily mean that the β-cell autoantibodies are pathogenic, but rather that they represent reproducible biomarkers of the pathogenesis. The primary risk factor for β-cell autoimmunity is genetic, mainly occurring in individuals with either HLA-DR3-DQ2 or HLA-DR4-DQ8 haplotypes, or both, but a trigger from the environment is generally needed. The pathogenesis can be divided into three stages: 1, appearance of β-cell autoimmunity, normoglycaemia, and no symptoms; 2, β-cell autoimmunity, dysglycaemia, and no symptoms; and 3, β-cell autoimmunity, dysglycaemia, and symptoms of diabetes. The genetic association with each one of the three stages can differ. Type 1 diabetes could serve as a disease model for organ-specific autoimmune disorders such as coeliac disease, thyroiditis, and Addison's disease, which show similar early markers of a prolonged disease process before clinical diagnosis.

    2014-01-01

    Background Diabetes history in biologically-related individuals increases diabetes risk. We assessed diabetes concordance in spouses (that is, biologically unrelated family members) to gauge the importance of socioenvironmental factors. Methods We selected cross-sectional, case–control and cohort studies examining spousal association for diabetes and/or prediabetes (impaired fasting glucose or impaired glucose tolerance), indexed in Medline, Embase or Scopus (1 January 1997 to 28 February 2013). Effect estimates (that is, odds ratios, incidence rate ratios, and so on) with body mass index (BMI) adjustment were pooled separately from those without BMI adjustment (random effects models) to distinguish BMI-dependent and independent concordance. Results Searches yielded 2,705 articles; six were retained (n = 75,498 couples) for systematic review and five for meta-analysis. Concordance was lowest in a study that relied on women’s reports of diabetes in themselves and their spouses (effect estimate 1.1, 95% CI 1.0 to 1.30) and highest in a study with systematic assessment of glucose tolerance (2.11, 95% CI 1.74 to 5.10). The random-effects pooled estimate adjusted for age and other covariates but not BMI was 1.26 (95% CI 1.08 to 1.45). The estimate with BMI adjustment was lower (1.18, 95% CI 0.97 to 1.40). Two studies assessing between-spouse associations of diabetes/prediabetes determined by glucose testing reported high concordance (OR 1.92, 95% CI 1.55 to 2.37 without BMI adjustment; 2.32, 95% CI 1.87 to 3.98 with BMI adjustment). Two studies did not distinguish type 1 and type 2 diabetes. However given that around 95% of adults is type 2, this is unlikely to have influenced the results. Conclusions Our pooled estimate suggests that a spousal history of diabetes is associated with a 26% diabetes risk increase. Recognizing shared risk between spouses may improve diabetes detection and motivate couples to increase collaborative efforts to optimize eating and

The results were surprisingly poor glycemic control among these young patients which lead to a great emphasis on glycemic control in the Danish Pediatric Departments. In 1995 the participants were invited for yet another evaluation but this time with main focus on early signs of microvascular complications - 339 participated. The mean HbA1c had remained at high levels (9.6%) and 60% of the participants had some level of Diabetic Retinopathy (DR). However, as the patients with DR mostly had the very milder forms it was believed that stricter glycemic control would reverse or at least stop progression of the disease in accordance with results from the large intervention study DCCT.

The first study in the present thesis aimed to describe the 16-year incidence, progression and regression of DR in 185 participants from the DCPD1987 cohort. The 16-year incidence of proliferative retinopathy (PDR), 2-step progression and regression of DR was 31.0, 64.4, and 0.0%, respectively. As expected, the participants with PDR at follow-up had significantly higher HbA1c-values at both baseline and follow-up than those without PDR. However; a significantly larger decrease in HbA1c was also observed in the group with PDR over the study period, which in accordance with DCCT should have prevented the development of PDR to some extent. A surprisingly high incidence of proliferative retinopathy amongst young patients with type 1 diabetes in Denmark was found despite improvements in HbA1c over time. The improvement in HbA1c was either too small or happened too late. This study highlights that sight-threatening diabetic retinopathy remain a major concern in type 1 diabetes and the importance

    Diabetes mellitus is a chronic condition that occurs when the body cannot produce enough or effectively use of insulin. Compared with individuals without diabetes, patients with type 2 diabetes mellitus have a considerably higher risk of cardiovascular morbidity and mortality, and are disproportionately affected by cardiovascular disease. Most of this excess risk is it associated with an augmented prevalence of well-known risk factors such as hypertension, dyslipidaemia and obesity in these patients. However the improved cardiovascular disease in type 2 diabetes mellitus patients can not be attributed solely to the higher prevalence of traditional risk factors. Therefore other non-traditional risk factors may be important in people with type 2 diabetes mellitus. Cardiovascular disease is increased in type 2 diabetes mellitus subjects due to a complex combination of various traditional and non-traditional risk factors that have an important role to play in the beginning and the evolution of atherosclerosis over its long natural history from endothelial function to clinical events. Many of these risk factors could be common history for both diabetes mellitus and cardiovascular disease, reinforcing the postulate that both disorders come independently from “common soil”. The objective of this review is to highlight the weight of traditional and non-traditional risk factors for cardiovascular disease in the setting of type 2 diabetes mellitus and discuss their position in the pathogenesis of the excess cardiovascular disease mortality and morbidity in these patients.

    The universal endocrine pathological state affecting young individuals and adults is type 2 diabetes mellitus, which has seen a significant increase in the last 30 years, particularly in children. Genetic and evnironmental factors are the causative agents for this pathological state in children. This rapid and wide spread of the disease can be controlled by enforcing amendments in environmental factors such as diet, physical activities and obesity. In young infants breastfeeding may be a key modulator of the disease. Associated disorders co-observed in the patients of type 2 diabetes mellitus include renal failure, heart problems and circulatory dysfunctionalities, such as cardiac failure and vision disability. These associated disorders become more pronounced in young patients when they reach puberty. To overcome the lethal outcomes of the disease, early screening of the disease is crucial. The present review focused on the latest updates in the field, as well as plausible risks and complications of this pathological state. PMID:27703500

    Background— Maternal diabetes mellitus is associated with an increased risk of offspring congenital heart defects (CHD); however, the causal mechanism is poorly understood. We further investigated this association in a Danish nationwide cohort. Methods and Results— In a national cohort study, we identified 2 025 727 persons born from 1978 to 2011; among them were 7296 (0.36%) persons exposed to maternal pregestational diabetes mellitus. Pregestational diabetes mellitus was identified by using the National Patient Register and individual-level information on all prescriptions filled in Danish pharmacies. Persons with CHD (n=16 325) were assigned to embryologically related cardiac phenotypes. The CHD prevalence in the offspring of mothers with pregestational diabetes mellitus was 318 per 10 000 live births (n=232) in comparison with a baseline risk of 80 per 10 000; the adjusted relative risk for CHD was 4.00 (95% confidence interval, 3.51–4.53). The association was not modified by year of birth, maternal age at diabetes onset, or diabetes duration, and CHD risks associated with type 1 (insulin-dependent) and type 2 (insulin-independent) diabetes mellitus did not differ significantly. Persons born to women with previous acute diabetes complications had a higher CHD risk than those exposed to maternal diabetes mellitus without complications (relative risk, 7.62; 95% confidence interval, 5.23–10.6, and relative risk, 3.49; 95% confidence interval, 2.91–4.13, respectively; P=0.0004). All specific CHD phenotypes were associated with maternal pregestational diabetes mellitus (relative risk range, 2.74–13.8). Conclusions— The profoundly increased CHD risk conferred by maternal pregestational diabetes mellitus neither changed over time nor differed by diabetes subtype. The association with acute pregestational diabetes complications was particularly strong, suggesting a role for glucose in the causal pathway. PMID:27166384

    Purpose The purpose of this qualitative study was to understand how acculturation influences diabetes risk among urban, immigrant Latinas (Hispanic women). Methods Five focus groups were conducted with 26 urban, immigrant Latinas who were at high clinical risk for developing diabetes. The focus group sessions were audiotaped and transcribed verbatim. The authors independently analyzed transcripts using an inductive method of open coding, and themes were established by consensus among authors. Results All of the participants were foreign-born and had low levels of acculturation. During the acculturation process, they noted changes in their lifestyle behaviors and the family context in which those behaviors are shaped. They reported that since living in the U.S., their improved economic circumstances led to increased consumption of less healthy foods and beverages and a more sedentary lifestyle. They also described changing family roles and responsibilities, including working outside the home, which constrained healthy food choices. However, they perceived that their position of influence within the family offered opportunities to help family members prevent diabetes. Conclusions Lifestyle interventions to prevent diabetes in Latinas should address their acculturation experiences, which impact family functioning and health behaviors related to diabetes risk. For example, given the perceived link between Latinas’ improved economic circumstances and their diabetes risk, prevention programs should incorporate strategies to help Latinas avoid adopting less healthy lifestyle behaviors that become affordable during the acculturation process.

    Type 2 diabetes in children and adolescents has become a prominent clinical issue in recent decades. Increasing numbers of young people have risk factors for type 2 diabetes, particularly obesity, indicating the need for effective type 2 diabetes prevention strategies. The aim of this review was to identify specific dietary strategies that optimize improvements in risk factors for type 2 diabetes in youth and hence reduce the risk of type 2 diabetes development. Our review of the current literature indicates that dietary interventions lead to weight loss when intervention adherence is high. However, in addition to weight loss, a diet that is reduced in carbohydrates may optimize improvements in other type 2 diabetes risk factors, including insulin resistance and hyperglycemia. While further research is needed to confirm this finding, reduced carbohydrate diets may include a very low-carbohydrate diet, a very low-energy diet, a lower-glycemic-index diet, and/or an intermittent fasting diet. This array of dietary strategies provides a suite of intervention options for clinicians to recommend to young people at risk of type 2 diabetes. However, these findings are in contrast to current guidelines for the prevention of type 2 diabetes in adults which recommends a low-fat, high-carbohydrate diet. PMID:27517953

    There is concern that egg intake may increase blood glucose in patients with type 2 diabetes mellitus (T2DM). However, we have previously shown that eggs reduce inflammation in patients at risk for T2DM, including obese subjects and those with metabolic syndrome. Thus, we hypothesized that egg intake would not alter plasma glucose in T2DM patients when compared to oatmeal intake. Our primary endpoints for this clinical intervention were plasma glucose and the inflammatory markers tumor necrosis factor (TNF)-α and interleukin 6 (IL-6). As secondary endpoints, we evaluated additional parameters of glucose metabolism, dyslipidemias, oxidative stress and inflammation. Twenty-nine subjects, 35–65 years with glycosylated hemoglobin (HbA1c) values <9% were recruited and randomly allocated to consume isocaloric breakfasts containing either one egg/day or 40 g of oatmeal with 472 mL of lactose-free milk/day for five weeks. Following a three-week washout period, subjects were assigned to the alternate breakfast. At the end of each period, we measured all primary and secondary endpoints. Subjects completed four-day dietary recalls and one exercise questionnaire for each breakfast period. There were no significant differences in plasma glucose, our primary endpoint, plasma lipids, lipoprotein size or subfraction concentrations, insulin, HbA1c, apolipoprotein B, oxidized LDL or C-reactive protein. However, after adjusting for gender, age and body mass index, aspartate amino-transferase (AST) (p < 0.05) and tumor necrosis factor (TNF)-α (p < 0.01), one of our primary endpoints were significantly reduced during the egg period. These results suggest that compared to an oatmeal-based breakfast, eggs do not have any detrimental effects on lipoprotein or glucose metabolism in T2DM. In contrast, eggs reduce AST and TNF-α in this population characterized by chronic low-grade inflammation. PMID:25970149

    Avoiding serious complications such as stroke, myocardial infarction, and amputations in diabetes patients is the main interest of long-term treatment. Given the considerable prevalence of diabetes type 2 in industrialized countries this is a major public health concern as well as a burden to health care systems. The present study estimated the current risk of major complications occurring in the German diabetes type 2 population and explored the potential for further risk reduction. Risk reduction can be achieved when physiological and behavioral parameters (HbAlc, blood pressure, cholesterol level, body mass index, smoking) are set to target values recommended in guidelines. To estimate individual risk and potential risk reduction the multifactor disease model Mellibase was employed. Data were obtained from the German Health Survey of 1998, which includes a sample of 7,124 individuals representative of the German population. The survey shows a prevalence rate of 6.3% for diabetes type 2 in persons older than 35 years. The analyses reveal that the overall potential for risk reduction is moderate (e.g., the average reduction potential of the 10-year risk of stroke is 5.7%). A majority of parameter ranges found in the patient population are either already close to the recommended values (HbA1c), are not alarmingly higher than in the general population (blood pressure) or have little impact on risk reduction. In addition nonmodifiable risk factors such as duration of the illness and advanced age constrain possible improvements. However, there is a wide variation in the actual risk between individuals (e.g., the 10-year risk of stroke varies between 2.2% and 79.8%), and thus a wide variation in potential risk reduction (the risk reduction potential for stroke varies between 0% and 53.4%). Intensified treatment should therefore (a) focus on relevant subgroups of patients taking their risk reduction potential into account and (b) aim at improvement in the overall

    OBJECTIVE To identify novel metabolic markers for diabetes development in American Indians. RESEARCH DESIGN AND METHODS Using an untargeted high-resolution liquid chromatography–mass spectrometry, we conducted metabolomics analysis of study participants who developed incident diabetes (n = 133) and those who did not (n = 298) from 2,117 normoglycemic American Indians followed for an average of 5.5 years in the Strong Heart Family Study. Relative abundances of metabolites were quantified in baseline fasting plasma of all 431 participants. Prospective association of each metabolite with risk of developing type 2 diabetes (T2D) was examined using logistic regression adjusting for established diabetes risk factors. RESULTS Seven metabolites (five known and two unknown) significantly predict the risk of T2D. Notably, one metabolite matching 2-hydroxybiphenyl was significantly associated with an increased risk of diabetes, whereas four metabolites matching PC (22:6/20:4), (3S)-7-hydroxy-2′,3′,4′,5′,8-pentamethoxyisoflavan, or tetrapeptides were significantly associated with decreased risk of diabetes. A multimarker score comprising all seven metabolites significantly improved risk prediction beyond established diabetes risk factors including BMI, fasting glucose, and insulin resistance. CONCLUSIONS The findings suggest that these newly detected metabolites may represent novel prognostic markers of T2D in American Indians, a group suffering from a disproportionately high rate of T2D.

    Distinguishing patients with monogenic diabetes from Type 1 diabetes (T1D) is important for correct diagnosis, treatment and to select patients for gene discovery studies. We assessed whether a T1D genetic risk score (T1D-GRS) generated from T1D-associated common genetic variants provides a novel way to discriminate monogenic diabetes from T1D. The T1D-GRS was highly discriminative of proven MODY (n=805) and T1D (n=1963) (ROC-AUC=0.87). A T1D-GRS of >0.280 (>50th T1D centile) was indicative of T1D (94% specificity, 50% sensitivity). We then analyzed the T1D-GRS in 242 White-European patients with neonatal diabetes (NDM) who had been tested for all known neonatal diabetes genes. Monogenic NDM was confirmed in 90%, 59% and 8% in patients with GRS <5th T1D centile, 50-75th T1D centile and >75th T1D centile, respectively. Applying a GRS 50th T1D centile cut-off in 48 NDM patients with no known genetic cause, identified those most likely to have a novel monogenic etiology by highlighting patients with probable early-onset T1D (GRS >50th T1D centile) who were diagnosed later, had less syndromic presentation but had additional autoimmune features compared to proven monogenic NDM. The T1D-GRS is a novel tool to improve the use of biomarkers in the discrimination of monogenic diabetes from T1D. PMID:27207547

    Cancer is the second cause of death. Association of diabetes as a growing and costly disease with cancer is a major health concern. Meanwhile, preexisting diabetes is associated with an increased risk of all-cause and cancer-specific mortalities. Presence of diabetes related comorbidities, poorer response to cancer treatment, and excess mortality related to diabetes are among the most important explanations. Although diabetes appear to be a risk factor for cancer and is associated with the mortality risk in cancer patients, several factors such as diabetes duration, multiple drug therapy, and the presence of diabetes comorbidities make the assessment of the effect of diabetes treatment on cancer risk and mortality difficult. Metformin is the drug of choice for the treatment of type 2 diabetes. The available evidence from basic science, clinical, and population-based research supports the anticancer effect of metformin. However, randomized controlled clinical trials do not provide enough evidence for a strong protective effect of metformin on cancer incidence or mortality. One of the most important limitations of these trials is the short duration of the followup. Further long-term randomized controlled clinical trials specifically designed to determine metformin effect on cancer risk are needed to provide the best answer to this challenge. PMID:24224094

    The Scottish Diabetes Foot Action Group (SDG) has developed and introduced a national strategy plan for diabetic foot care across Scotland. This has involved the implementation of an evidence-based national foot screening and risk stratification programme that has already covered 61% of the population in just the first two years. Nationally agreed patient information foot leaflets and professional education material have been introduced, and a consensus for antibiotic use in the diabetic foot has been published. Information on multidisciplinary specialist foot services has been collected, indicating that 58% of Health Board areas have consultants with dedicated sessions in their job plan to a foot clinic, and 42% had integrated orthotic involvement. The SDG aims to increase these figures. Work has been undertaken to support local podiatry networks and improve communication between the specialist centre and the community. At a national level the SDG is working with Foot in Diabetes UK (FDUK) to recognize key podiatry skills by developing core competencies and a competency framework for the diabetes podiatrist and diabetes orthotist. The annual Scottish Diabetes Survey indicates some improvement in amputation rates with prevalence decreasing from 0.8% to 0.5%, and improved recording of foot ulceration at a national level. This national strategy has helped highlight the importance and difficulties facing diabetes foot care and should help to continue to improve the quality of care of people with diabetes who have foot-related problems.

    Physical activity is a proven form of diabetes management and is considered a cornerstone in the prevention of diabetes. In children with diabetes, physical activity may improve insulin sensitivity and glucose uptake in skeletal muscle. Aerobic-based physical activity lasting 40-60 minutes daily for a minimum of four months is shown to enhance…

  12. Environmental contaminants as risk factors for developing diabetes.

    The contribution of exposure to persistent organic pollutants (POPs) to the incidence of diabetes has received little attention until recently. A number of reports have emerged, however, concerning elevated diabetes in persons occupationally exposed to dioxin. United States (US) Air Force personnel in Vietnam who sprayed Agent Orange containing dioxin as a contaminant had elevated rates of diabetes, leading to US government compensation for diabetes in these veterans. Recent studies in populations exposed to polychlorinated biphenyls (PCBs) and chlorinated pesticides found a dose-dependent elevated risk of diabetes. An elevation in risk of diabetes in relation to levels of several POPs has been demonstrated by two different groups using the National Health and Nutrition Examination Survey (NHANES), a random sampling of US citizens. The strong associations seen in quite different studies suggest the possibility that exposure to POPs could cause diabetes. One striking observation is that obese persons that do not have elevated POPs are not at elevated risk of diabetes, suggesting that the POPs rather than the obesity per se is responsible for the association. Although a specific mechanism is not known, most POPs induce a great number and variety of genes, including several that alter insulin action. Because diabetes is a dangerous disease that is increasing in frequency throughout the world, further study of the possibility that exposure to POPs contributes to the etiology of diabetes is critical.

    A substantial number of pregnancies are complicated by gestational diabetes mellitus (GDM) and up to 70 % of women with GDM go on to develop type 2 diabetes. Given the extensive body of research suggesting physical activity reduces the risk of type 2 diabetes, facilitating physical activity, and reducing sedentary time may be effective approaches to promote the health of women with a previous GDM diagnosis. Here, we discuss physical activity, exercise, and sedentary behavior, in the context of GDM and the potential for type 2 diabetes risk reduction. PMID:26823010

    Patients with diabetes, in particular patients with type 2 diabetes, are at a 2- to 4-fold higher risk of cardiovascular mortality compared with their nondiabetic peers. Patients with diabetes are also more likely to have silent ischemia and less likely to survive a myocardial infarction than nondiabetic patients. Recent studies with electron beam computed tomography (EBCT) have shown that subclinical atherosclerosis is common in patients with diabetes, and studies with myocardial perfusion scintigraphy (with single-photon emission computed tomography) or stress echocardiography have demonstrated that between 25% and 50% of asymptomatic diabetic patients have ischemia during exercise or pharmacological stress and that a substantial proportion of these patients go on to develop major cardiovascular events within several years. Clearly, asymptomatic diabetic patients include a subset of individuals at high risk of cardiovascular disease who would benefit from improved risk stratification beyond that possible with risk factor scoring systems alone. Single-photon emission computed tomography, stress echocardiography, and possibly EBCT or multi-slice computed tomography, are emerging as valuable diagnostic tools for identifying asymptomatic diabetic patients who might require early and aggressive intervention to manage their cardiovascular risk.

    Behavioural economics refers to the study of psychological and cognitive factors that relate to decision-making processes. This field is being applied increasingly to health care settings, in which patients receive tangible reinforcers or incentives for meeting objective behavioural criteria consistent with healthy lifestyles. This article reviews the background and efficacy of reinforcement interventions in general, and then as applied to behaviours related to diabetes prevention and management. Specifically, reinforcement interventions have been applied with some notable success towards promoting greater attendance at medical appointments, enhancing weight loss efforts, augmenting exercising regimes, improving medication adherence and increasing blood glucose monitoring. Suggestions for promising areas of future research are provided, keeping in mind the controversial nature of these interventions.

    Objective To evaluate the impact of a multifaceted, school-based intervention on inner city youth at high risk for type 2 diabetes mellitus (T2DM) and to determine whether the addition of coping skills training (CST) and health coaching improves outcomes. Method 198 students in New Haven, CT at risk for T2DM (BMI > 85th percentile and family history of diabetes) were randomized by school to an educational intervention with or without the addition of CST and health coaching. Students were enrolled from 2004–2007 and followed for 12 months. Results Students in both groups showed some improvement in anthropometric measures, lipids, and depressive symptoms over 12 months. BMI was not improved by the intervention. Students who received CST showed greater improvement on some indicators of metabolic risk than students who received education only. Conclusion A multifaceted, school-based intervention may hold promise for reducing metabolic risk in urban, minority youth. PMID:19643125

    The rapidly increasing rate of non-insulin-dependent diabetes (NIDDM) among both market economy and developing countries is a worldwide health phenomenon. The number of diabetics worldwide has been projected to increase from 135 million in 1995 to 300 million in 2025. The purpose of this study was to examine the relative effectiveness of three different approaches to the implementation of the Diabetes Prevention Program, a standardized diabetes prevention curriculum, in various worksite organizations within a single community. The methods of implementation selected included an intensive one-on-one counseling approach, a support group meeting approach, and a passive transfer of information approach. The intervention was successful in creating significant mean improvements overall in the participants who completed the 26-week program as follows: (a) reduction in overall mean body weight and mean body mass index, (b) reduction in overall average mean arterial blood pressure, (c) reduction in overall mean diabetes risk score, and (d) increase in overall mean physical activity level. Although the largest proportion of these changes occurred in the one-on-one intervention group, significant changes in some factors were found in all groups. This illustrates the utility of an on-site and incentive-driven approach to diabetes risk factor modification in the workplace.

    Despite substantial progress in the study of diabetes, important questions remain about its comorbidities and clinical heterogeneity. To explore these issues, we develop a framework allowing for the first time to quantify nation-wide risks and their age- and sex-dependence for each diabetic comorbidity, and whether the association may be consequential or causal, in a sample of almost two million patients. This study is equivalent to nearly 40,000 single clinical measurements. We confirm the highly controversial relation of increased risk for Parkinson's disease in diabetics, using a 10 times larger cohort than previous studies on this relation. Detection of type 1 diabetes leads detection of depressions, whereas there is a strong comorbidity relation between type 2 diabetes and schizophrenia, suggesting similar pathogenic or medication-related mechanisms. We find significant sex differences in the progression of, for instance, sleep disorders and congestive heart failure in diabetic patients. Hypertension is a highly sex-sensitive comorbidity with females being at lower risk during fertile age, but at higher risk otherwise. These results may be useful to improve screening practices in the general population. Clinical management of diabetes must address age- and sex-dependence of multiple comorbid conditions.

    2013-04-01

    Unchecked, the increasing prevalence of prediabetes can be predicted to only expand the numbers of people developing type 2 diabetes and all its associated health ramifications. People with obesity and prediabetes who are able to manage their body weight are known to decrease their risk of developing diabetes. However, making the changes to diet and levels of physical activity is a difficult proposition for many people. Diabetes educators are a group of healthcare professionals trained to work with people who have diabetes on appropriate goal-setting around self-care behaviors including healthy eating and physical activity to better enable them to accomplish the changes needed for better health outcomes. Applying this same skill set to people with prediabetes provides a ready means for addressing the needs of this population to help diminish their risk of developing diabetes.

    Background and objectives Quantitative data for prediction of incidence and progression of early CKD are scarce in individuals with type 2 diabetes. Therefore, two risk prediction models were developed for incidence and progression of CKD after 5.5 years and the relative effect of predictors were ascertained. Design, setting, participants, & measurements Baseline and prospective follow-up data of two randomized clinical trials, ONgoing Telmisartan Alone and in combination with Ramipril Global Endpoint Trial (ONTARGET) and Outcome Reduction with Initial Glargine Intervention (ORIGIN), were used as development and independent validation cohorts, respectively. Individuals aged ≥55 years with type 2 diabetes and normo- or microalbuminuria at baseline were included. Incidence or progression of CKD after 5.5 years was defined as new micro- or macroalbuminuria, doubling of creatinine, or ESRD. The competing risk of death was considered as an additional outcome state in the multinomial logistic models. Results Of the 6766 ONTARGET participants with diabetes, 1079 (15.9%) experienced incidence or progression of CKD, and 1032 (15.3%) died. The well calibrated, parsimonious laboratory prediction model incorporating only baseline albuminuria, eGFR, sex, and age exhibited an externally validated c-statistic of 0.68 and an R2 value of 10.6%. Albuminuria, modeled to depict the difference between baseline urinary albumin/creatinine ratio and the threshold for micro- or macroalbuminuria, was mostly responsible for the predictive performance. Inclusion of clinical predictors, such as glucose control, diabetes duration, number of prescribed antihypertensive drugs, previous vascular events, or vascular comorbidities, increased the externally validated c-statistic and R2 value only to 0.69 and 12.1%, respectively. Explained variation was largely driven by renal and not clinical predictors. Conclusions Albuminuria and eGFR were the most important factors to predict onset and

    We present a new approach to population health, in which data-driven predictive models are learned for outcomes such as type 2 diabetes. Our approach enables risk assessment from readily available electronic claims data on large populations, without additional screening cost. Proposed model uncovers early and late-stage risk factors. Using administrative claims, pharmacy records, healthcare utilization, and laboratory results of 4.1 million individuals between 2005 and 2009, an initial set of 42,000 variables were derived that together describe the full health status and history of every individual. Machine learning was then used to methodically enhance predictive variable set and fit models predicting onset of type 2 diabetes in 2009-2011, 2010-2012, and 2011-2013. We compared the enhanced model with a parsimonious model consisting of known diabetes risk factors in a real-world environment, where missing values are common and prevalent. Furthermore, we analyzed novel and known risk factors emerging from the model at different age groups at different stages before the onset. Parsimonious model using 21 classic diabetes risk factors resulted in area under ROC curve (AUC) of 0.75 for diabetes prediction within a 2-year window following the baseline. The enhanced model increased the AUC to 0.80, with about 900 variables selected as predictive (p < 0.0001 for differences between AUCs). Similar improvements were observed for models predicting diabetes onset 1-3 years and 2-4 years after baseline. The enhanced model improved positive predictive value by at least 50% and identified novel surrogate risk factors for type 2 diabetes, such as chronic liver disease (odds ratio [OR] 3.71), high alanine aminotransferase (OR 2.26), esophageal reflux (OR 1.85), and history of acute bronchitis (OR 1.45). Liver risk factors emerge later in the process of diabetes development compared with obesity-related factors such as hypertension and high hemoglobin A1c. In conclusion

    Background Diabetic foot is a serious condition in patients with a long lasting diabetes mellitus. Diabetic foot treated improperly may lead not only to delayed ulceration healing, generalized inflammation, unnecessary surgical intervention, but also to the lower limb amputation. The aim of this study was to compare diabetic foot risk factors in population with type 2 diabetes and risk factors for diabetes in healthy subjects. Methods The study included 900 subjects: 145 with diabetic foot, 293 with type 2 diabetes without diabetic foot and 462 healthy controls matched in terms of mean age, gender structure and cardiovascular diseases absence. Study was conducted in Gastroenterology and Metabolic Diseases Department, Medical University of Warsaw, Poland. In statistical analysis a logistic regression model, U Mann-Whitney’s and t-Student test were used. Results The binomial logit models analysis showed that the risk of diabetic foot in patients with type 2 diabetes was decreased by patient’s age (odds ratio [OR] = 0.94; 95% confidence interval [CI]: 0.92-0.96; p = 0.00001) and hyperlipidaemia (OR = 0.54; 95% CI: 0.36-0.81; p = 0.01). In contrast, male gender (OR = 2.83; 95% CI: 1.86-4.28; p = 0.00001) diabetes duration (OR = 1.04; 95% CI: 1.03-1.06; p = 0.0003), weight (OR = 1.04; 95% CI: 1.03-1.06; p = 0.00001), height (OR = 1.08; 95% CI: 1.05-1.11; p = 0.00001) and waist circumference (OR = 1.028; 95% CI: 1.007-1.050; p = 0.006) increase the risk of diabetic foot. The onset of type 2 diabetes in healthy subjects was increased by weight (OR = 1.035; 95% CI: 1.024-1.046; p = 0.00001), WC (OR = 1.075; 95% CI: 1.055-1.096; p = 00001), hip circumference (OR = 1.03; 95% CI: 1.01-1.05; p = 0.005), overweight defined with body mass index (BMI) above 24,9 kg/m2 (OR = 2.49; 95% CI: 1.77-3.51; p = 0.00001) and hyperlipidaemia (OR = 3.53; 95% CI: 2.57-4.84; p = 0.00001).

    Diabetes affects 25.8 million persons in the United States, and these persons make more than 35 million ambulatory care visits annually. Yet, less than half of persons with diabetes meet the recommended levels of A1C, blood pressure and lipid control. One innovative approach is to use mobile health technologies to help patients better manage their diabetes and related conditions, and 85% to 90% of patients have access to mobile health technology. A brief review of the guidelines for diabetes care and mobile health technology that can support the guidelines are reported related to (1) glycemic control and self-monitoring of blood glucose, (2) pharmacological approaches and medication management, (3) medical nutrition therapy, (4) physical activity and resistance training, (5) weight loss, (6) diabetes self-management education and (7) blood pressure control and hypertension.

    Diabetes affects 29 million Americans and is associated with billions of dollars in health expenditures and lost productivity. Robust evidence has shown that lifestyle interventions in people at high risk for diabetes and comprehensive management of cardiometabolic risk factors like glucose, blood pressure, and lipids can delay the onset of diabetes and its complications, respectively. However, realizing the "triple aim" of better health, better care, and lower cost in diabetes has been hampered by low adoption of lifestyle interventions to prevent diabetes and poor achievement of care goals for those with diabetes. To achieve better care, a number of quality improvement (QI) strategies targeting the health system, healthcare providers, and/or patients have been evaluated in both controlled trials and real-world programs, and have shown some successes, though barriers still impede wider adoption, effectiveness, real-world feasibility, and scalability. Here, we summarize the effectiveness and cost-effectiveness data regarding QI strategies in diabetes care and discuss the potential role of quality monitoring and QI in trying to implement primary prevention of diabetes more widely and effectively. Over time, achieving better care and better health will likely help bend the ever-growing cost curve. PMID:26495771

    Objective Gut microbiota influence metabolic pathways relevant to the pathogenesis of obesity, insulin-resistance and diabetes. Antibiotic therapy can alter the microbiota and is commonly used in western countries. We sought to evaluate whether past antibiotic exposure increases diabetes risk. Research design and methods We conducted a nested case-control study using a large population-based database from the United Kingdom (UK). Cases were defined as those with incident diagnosis of diabetes. For every case, 4 eligible controls matched on age, sex, practice-site, and duration of follow-up before index-date were selected using incidence-density sampling. Exposure of interest was antibiotic therapy >1 year before index-date. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using conditional logistic regression. The risk was adjusted for body mass index (BMI), smoking, last glucose level and number of infections before index-date, as well as past medical history of coronary artery disease and hyperlipidemia. Results The study included 208,002 diabetic cases and 815,576 matched controls. Exposure to a single antibiotic prescription was not associated with higher adjusted diabetes risk. Treatment with 2–5 antibiotic courses was associated with increase in diabetic risk for penicillin, cephalosporins, macrolides and quinolones with adjusted OR ranging from 1.08 (95%CI 1.05–1.11) for penicillin to 1.15 (95%CI 1.08–1.23) for quinolones. The risk increased with the number of antibiotic courses and reached 1.37 (95%CI 1.19–1.58) for >5 courses of quinolones. There was no association between exposure to anti-virals and anti-fungals and diabetes risk. Conclusions Exposure to certain antibiotic groups increases diabetes risk. PMID:25805893

  11. Rare neonatal diabetes insipidus and associated late risks: Case report

    PubMed Central

    2012-01-01

    Background Most cases of neonatal central diabetes insipidus are caused by an injury, which often results in other handicaps in the patient. The infant’s prognosis will be determined by his or her own early age and disability as well as by the physician’s skill. However, the rarity of this condition prevents the acquisition of personal experience dealing with it. Case Presentation A neonatal hemorrhagic stroke, caused by an aortic coarctation, caused right lower limb paresis, swallowing disability, and central diabetes insipidus in a term infant. The scant oral intake, as a consequence of his disability, caused progressive undernutrition which closed a vicious circle, delaying his development and his ability to overcome the swallowing handicap. On the other hand, nasal desmopressin absorption was blocked by several common colds, resulting in brain bleeding because of severe dehydration. This even greater brain damage hampered the improvement of swallowing, closing a second harmful circle. Moreover, a devastating central myelinolysis with quadriplegia, caused by an uncontrolled intravenous infusion, consummated a pernicious sequence, possibly unreported. Conclusions The child’s overall development advanced rapidly when his nutrition was improved by gastrostomy: This was a key effect of nutrition on his highly sensitive neurodevelopment. Besides, this case shows potential risks related to intranasal desmopressin treatment in young children. PMID:22639945

    Objectives: To assess the proportion and grades of retinopathy and its risk factors in diabetes type 2 patients. Materials and Methods: This was a cross-sectional study of 401 type 2 diabetic patients. A questionnaire and checklist were used to collect the data. Retinopathy was diagnosed and graded by fundus photographs and slit lamp examination. The duration of diabetes, age of patients, age at onset of diabetes, body mass index, hemoglobin A1c level, blood pressure, and complications were noted. Results: The mean age of male and female patients was 54.93 and 54.25 years; 57.6% were males. The mean age of onset and mean duration of diabetes were 43.91 and 13.4 years, respectively. The proportion of retinopathy was 36.4%. Grades of retinopathy were: Mild 57.5%, moderate 19.9%, severe nonproliferative 11%, and proliferative retinopathy 11.6%; 7.2% of patients had maculopathy. Retinopathy was significantly associated with older age, younger age at onset, longer duration of disease, poorly controlled blood sugar, hypertension, insulin use; the presence of neuropathy and nephropathy appeared as a significant risk. Younger age at onset, longer duration, and insulin use appeared as the strongest predictors for diabetic retinopathy. Conclusions: More than a third (36.4%) of the diabetic patients attending a diabetic center had retinopathy. The control of the risk factors may reduce both prevalence and consequences of retinopathy. PMID:26929725

    Patients with diabetes type 2 are not directly endangered by dysglycemia but they suffer vascular complications. The diabetic patient with existing cardiovascular disease has a particularly high risk for further cardiovascular complications and therefore requires specific attention. This is not only due to the hyperglycemia, but due to the coexistence of further cardiovascular risk factors, such as hypertension, dyslidemia, visceral fat accumulation, chronic inflammation and coagulopathy, also clinically described as the metabolic syndrome. These patients need an intense and multi-modal therapeutic approach, not only for improvement of glycemic control. Also other vascular risk factors should be handled aggressively, such as blood pressure, coagulopathy and dyslipidemia. Recent studies--as STENO 2--indicate that a multi-modal and aggressive approach in diabetic patients can markedly improve their prognosis. Therefore, the current practice of a glucocentric approach should be changed towards a more vascular approach.

  16. Sulfonylurea pharmacogenomics in Type 2 diabetes: the influence of drug target and diabetes risk polymorphisms

    The sulfonylureas stimulate insulin release from pancreatic β cells, and have been a cornerstone of Type 2 diabetes pharmacotherapy for over 50 years. Although sulfonylureas are effective antihyperglycemic agents, interindividual variability exists in drug response (i.e., pharmacodynamics), disposition (i.e., pharmacokinetics) and adverse effects. The field of pharmacogenomics has been applied to sulfonylurea clinical studies in order to elucidate the genetic underpinnings of this response variability. Historically, most studies have sought to determine the influence of polymorphisms in drug-metabolizing enzyme genes on sulfonylurea pharmacokinetics in humans. More recently, polymorphisms in sulfonylurea drug target genes and diabetes risk genes have been implicated as important determinants of sulfonylurea pharmacodynamics in patients with Type 2 diabetes. As such, the purpose of this review is to discuss sulfonylurea pharmacogenomics in the setting of Type 2 diabetes, specifically focusing on polymorphisms in drug target and diabetes risk genes, and their relationship with interindividual variability in sulfonylurea response and adverse effects.

    The incidence of type 1 diabetes has risen considerably in the past 30 years due to changes in the environment that have been only partially identified. In this Series paper, we critically discuss candidate triggers of islet autoimmunity and factors thought to promote progression from autoimmunity to overt type 1 diabetes. We revisit previously proposed hypotheses to explain the growth in the incidence of type 1 diabetes in light of current data. Finally, we suggest a unified model in which immune tolerance to β cells can be broken by several environmental exposures that induce generation of hybrid peptides acting as neoautoantigens.

    Bone marrow (BM) derived stem and progenitor cells contribute to cardiovascular homeostasis and are affected by cardiovascular risk factors. We devised a clinical data-driven approach to test candidate stem cell mobilizing mechanisms in pre-clinical models. We found that PB and BM CD34+ cell counts were directly correlated, and that most circulating CD34+ cells were viable, non-proliferating and derived from the BM. Thus, we analyzed PB and BM CD34+ cell levels as a two-compartment model in 72 patients with or without cardiovascular disease. Self-organizing maps showed that disturbed compartmentalization of CD34+ cells was associated with aging and cardiovascular risk factors especially diabetes. High activity of DPP-4, a regulator of the mobilizing chemokine SDF-1α, was associated with altered stem cell compartmentalization. For validation of these findings, we assessed the role of DPP-4 in the BM mobilization response of diabetic rats. Diabetes differentially affected DPP-4 activity in PB and BM and impaired stem/progenitor cell mobilization after ischemia or G-CSF administration. DPP-4 activity in the BM was required for the mobilizing effect of G-CSF, while in PB it blunted ischemia-induced mobilization. Indeed, DPP-4 deficiency restored ischemia (but not G-CSF)-induced stem cell mobilization and improved vascular recovery in diabetic animals. In conclusion, the analysis of stem cell compartmentalization in humans led us to discover mechanisms of BM unresponsiveness in diabetes determined by tissue-specific DPP-4 dysregulation.

    In a nationwide incident case referent study we have evaluated vaccinations, early and recent infections and the use of medicines as possible risk determinants for Type 1 (insulin-dependent) diabetes mellitus in childhood. A total of 339 recently onset diabetic and 528 referent children, age 0-14 years, were included. Information about infections was collected from a mailed questionnaire and about vaccinations from childhood health care centres and schools. When vaccinations were considered as possible risk factors for diabetes, a significant decrease in relative risk estimated as odds ratio (OR) was noted for measles vaccination (OR = 0.69; 95% confidence limits 0.48-0.98). For vaccination against tuberculosis, smallpox, tetanus, whooping cough, rubella and mumps no significant effect on OR for diabetes was found. The odds ratios for Type 1 diabetes for children exposed to 0.1-2 or over 2 infections during the last year before diagnosis of diabetes revealed a linear increase (OR = 1.0, 1.96 and 2.55 for 0, 1-2 and over 2 infections, respectively). The trend was still significant when standardized for possible confounders such as age and sex of the children, maternal age and education and intake of antibiotics and analgetics. In conclusion, a protective effect of measles vaccination for Type 1 diabetes in childhood is indicated as well as a possible causal relationship between the onset of the disease and the total load of recent infections.

    OBJECTIVE To investigate the association between vitamin D status, assessed by plasma 25-hydroxyvitamin D, and risk of incident diabetes. RESEARCH DESIGN AND METHODS Prospective observational study with a mean follow-up of 2.7 years in the Diabetes Prevention Program (DPP), a multicenter trial comparing different strategies for prevention of diabetes in patients with prediabetes. We assessed the association between plasma 25-hydroxyvitamin D, measured repeatedly during follow-up, and incident diabetes in the combined placebo (n = 1,022) and intensive lifestyle (n = 1,017) randomized arms of the DPP. Variables measured at multiple study time points (25-hydroxyvitamin D, BMI, and physical activity) entered the analyses as time-varying “lagged” covariates, as the mean of the previous and current visits at which diabetes status was assessed. RESULTS After multivariate adjustment, including for the DPP intervention, participants in the highest tertile of 25-hydroxyvitamin D (median concentration, 30.1 ng/mL) had a hazard ratio of 0.72 (95% CI 0.56–0.90) for developing diabetes compared with participants in the lowest tertile (median concentration, 12.8 ng/mL). The association was in the same direction in placebo (0.70; 0.52–0.94) versus lifestyle arm (0.80; 0.54–1.17). CONCLUSIONS Higher plasma 25-hydroxyvitamin D, assessed repeatedly, was associated with lower risk of incident diabetes in high-risk patients, after adjusting for lifestyle interventions (dietary changes, increased physical activity, and weight loss) known to decrease diabetes risk. Because of the observational nature of the study, the potential association between vitamin D and diabetes needs to be confirmed in intervention studies. PMID:22323410

    Importance Optimization of glycemic control is critical to reduce diabetes related complications, but long-term success is challenging. Although vision loss is among the greatest fears of individuals with diabetes, comprehensive personalized diabetes education and risk assessments are not consistently employed in ophthalmology settings. Objective To determine whether point-of-care measurement of HbA1c and personalized diabetes complication risk assessments performed during retinal ophthalmology visits improve glycemic control as assessed by HA1c. Design/Setting Ophthalmologist office based clinical trial where investigators from 42 sites were randomly assigned to provide either study-prescribed augmented diabetes assessment and education, or usual care. Participants Adults with type 1 or 2 diabetes enrolled into two cohorts: “more frequent” than annual follow-up (502 control and 488 intervention participants) and “annual” follow-up (368 and 388 participants). Intervention(s) Point-of-care measurement of HbA1c, blood pressure, and retinopathy severity; individualized estimate of retinopathy progression risk derived from the visit findings; structured comparison and review of past and current clinical findings; and structured education with immediate assessment and feedback regarding participant understanding. Intervention was performed at enrollment and routine ophthalmic follow-up visits scheduled at least 12 weeks apart. Main Outcome Measure(s) Mean change in HbA1c from baseline to 1 year. Secondary outcomes included body mass index, blood pressure, and diabetes self-management practices and attitudes surveys. Results In the “more frequent” cohort, mean (SD) change in HbA1c at 1 year was −0.1% (1.5%) in the control group and −0.3% (1.4%) in the intervention group (adjusted mean difference −0.09%, 95% confidence interval −0.29% to +0.12%, P=0.35). In the “annual” cohort, mean (SD) change in HBA1c was 0.0% (1.1%) and −0.1% (1

    Type-2 Diabetes Mellitus is a growing epidemic that often leads to severe complications. Effective preventive measures exist and identifying patients at high risk of diabetes is a major health-care need. The use of association rule mining (ARM) is advantageous, as it was specifically developed to identify associations between risk factors in an interpretable form. Unfortunately, traditional ARM is not directly applicable to survival outcomes and it lacks the ability to compensate for confounders and to incorporate dosage effects. In this work, we propose Survival Association Rule (SAR) Mining, which addresses these shortcomings. We demonstrate on a real diabetes data set that SARs are naturally more interpretable than the traditional association rules, and predictive models built on top of these rules are very competitive relative to state of the art survival models and substantially outperform the most widely used diabetes index, the Framingham score.

    BACKGROUND Depression is common in patients with diabetes, but it is often inadequately treated within primary care. Competing clinical demands and treatment resistance may make it especially difficult to improve depressive symptoms in patients with diabetes who have multiple complications. OBJECTIVE To determine whether a collaborative care intervention for depression would be as effective in patients with diabetes who had 2 or more complications as in patients with diabetes who had fewer complications. DESIGN The Pathways Study was a randomized control trial comparing collaborative care case management for depression and usual primary care. This secondary analysis compared outcomes in patients with 2 or more complications to patients with fewer complications. PATIENTS Three hundred and twenty-nine patients with diabetes and comorbid depression were recruited through primary care clinics of a large prepaid health plan. MEASUREMENTS Depression was assessed at baseline, 3, 6, and 12 months with the 20-item depression scale from the Hopkins Symptom Checklist. Diabetes complications were determined from automated patient records. RESULTS The Pathways collaborative care intervention was significantly more successful at reducing depressive symptoms than usual primary care in patients with diabetes who had 2 or more complications. Patients with fewer than 2 complications experienced similar reductions in depressive symptoms in both intervention and usual care. CONCLUSION Patients with depression and diabetes who have multiple complications may benefit most from collaborative care for depression. These findings suggest that with appropriate intervention depression can be successfully treated in patients with diabetes who have the highest severity of medical problems. PMID:16836628

    Diabetes self-care is a critical aspect of disease management for adults with diabetes. Since family members can play a vital role in a patient’s disease management, involving them in self-care interventions may positively influence patients’ diabetes outcomes. We systematically reviewed family-based interventions for adults with diabetes published from 1994 to 2014 and assessed their impact on patients’ diabetes outcomes and the extent of family involvement. We found 26 studies describing family-based diabetes interventions for adults. Interventions were conducted across a range of patient populations and settings. The degree of family involvement varied across studies. We found evidence for improvement in patients’ self-efficacy, perceived social support, diabetes knowledge, and diabetes self-care across the studies. Owing to the heterogeneity of the study designs, types of interventions, reporting of outcomes, and family involvement, it is difficult to determine how family participation in diabetes interventions may affect patients’ clinical outcomes. Future studies should clearly describe the role of family in the intervention, assess quality and extent of family participation, and compare patient outcomes with and without family involvement.

    Higher body mass index (BMI) is a well-established risk factor for type 2 diabetes, and rates of obesity and type 2 diabetes are substantially higher among Mexican-Americans relative to non-Hispanic European Americans. Mexican-Americans are genetically diverse, with a highly variable distribution of Native American, European, and African ancestries. Here, we evaluate the role of Native American ancestry on BMI and diabetes risk in a well-defined Mexican-American population. Participants were randomly selected among individuals residing in the Houston area who are enrolled in the Mexican-American Cohort study. Using a custom Illumina GoldenGate Panel, we genotyped DNA from 4,662 cohort participants for 87 Ancestry-Informative Markers. On average, the participants were of 50.2% Native American ancestry, 42.7% European ancestry and 7.1% African ancestry. Using multivariate linear regression, we found BMI and Native American ancestry were inversely correlated; individuals with <20% Native American ancestry were 2.5 times more likely to be severely obese compared to those with >80% Native American ancestry. Furthermore, we demonstrated an interaction between BMI and Native American ancestry in diabetes risk among women; Native American ancestry was a strong risk factor for diabetes only among overweight and obese women (OR = 1.190 for each 10% increase in Native American ancestry). This study offers new insight into the complex relationship between obesity, genetic ancestry, and their respective effects on diabetes risk. Findings from this study may improve the diabetes risk prediction among Mexican-American individuals thereby facilitating targeted prevention strategies. PMID:26501420

    Diabetes is an important risk factor for erectile dysfunction (ED). Recent studies have indicated that A2B adenosine receptor (ADORA2B) signaling is essential for penile erection. Thus, we hypothesize that diabetic ED may be attributed to impaired A2B adenosine signaling. To test this hypothesis, we generated diabetic rats by injecting streptozocin as animal model. After 12 weeks, immunohistochemistry staining was used to localize the expression of ADORA2B. Western Blot and quantitative PCR were employed to determine ADORA2B expression level. Intracavernosal pressure (ICP) measurement was used to evaluate erectile function. Diabetic rats received a single intravenous injection of BAY 60-6583, an ADORA2B agonist, or vehicle solution, at 60 min before the ICP measurement. The results showed that ADORA2B expressed in the nerve bundle, smooth muscle, and endothelium in penile tissue of control mice. Western Blot and quantitative PCR results indicated that the expression levels of ADORA2B protein and mRNA were significantly reduced in penile tissues of diabetic rats. Functional studies showed that the erectile response induced by electrical stimulation was remarkably decreased in diabetic rats, compared with age-matched control rats. However, at 60 min after BAY 60-6583 treatment, the erectile function was improved in diabetic rats, suggesting that enhancement of ADORA2B signaling may improve erectile function in diabetic ED. This preclinical study has revealed a previously unrecognized therapeutic possibility of BAY 60-6583 as an effective and mechanism-based drug to treat diabetic ED. In conclusion, we propose that impaired A2B adenosine signaling is one of the pathological mechanisms of diabetic ED.

    Aims To examine the associations of the liver enzymes alanine aminotransferase, aspartate aminotransferase and gamma-glutamyl transferase with diabetes risk and to determine whether associations differ by race and/or gender. We hypothesized that all liver enzymes would be associated with diabetes risk and that associations would differ by race and gender. Methods Prospective cohort of 7495 white and 1842 black participants without diabetes in the Atherosclerosis Risk in Communities Study. Poisson and Cox models adjusted for demographic, socio-behavioural, and metabolic and health-related factors were used. Results During a median of 12 years of follow-up, 2182 incident cases of diabetes occurred. Higher liver enzyme levels were independently associated with diabetes risk: adjusted hazard ratios (95% confidence intervals) were 1.68 (1.49–1.89), 1.16 (1.02–1.31) and 1.95 (1.70–2.24) comparing the highest with the lowest quartiles of alanine aminotransferase, aspartate aminotransferase (AST) and gamma-glutamyl transferase (GGT), respectively. gamma-Glutamyl transferase was most strongly related to diabetes risk, even at levels considered within normal range (≤ 60 U/l) in clinical practice. Adjusted incidence rates by quartiles of liver enzymes were similar by gender but higher in black versus white participants. Nonetheless, relative associations of alanine aminotransferase, aspartate aminotransferase, and gamma-glutamyl transferase (GGT) with diabetes were similar by race (P for interactions > 0.05). Conclusions Compared with aspartate aminotransferase and alanine aminotransferase, gamma-glutamyl transferase was more strongly associated with diabetes risk. Our findings suggest that abnormalities in liver enzymes precede the diagnosis of diabetes by many years and that individuals with elevated liver enzymes, even within the normal range as defined in clinical practice, are at high risk for diabetes.

    Cardiac rehabilitation is a comprehensive multidisciplinary program individually tailored to the needs of patients with cardiovascular disease. The overall goals focus on improving daily function and reducing cardiovascular risk factors. Cardiac rehabilitation includes interventions aimed at lowering blood pressure and improving lipid and diabetes mellitus control, with tobacco cessation, behavioral counseling, and graded physical activity. The physical activity component typically involves 36 sessions over 12 weeks, during which patients participate in supervised exercise under cardiac monitoring. There are also intensive programs that include up to 72 sessions lasting up to 18 weeks, although these programs are not widely available. Additional components of cardiac rehabilitation include counseling on nutrition, screening for and managing depression, and assuring up-to-date immunizations. Cardiac rehabilitation is covered by Medicare and recommended for patients following myocardial infarction, bypass surgery, and stent placement, and for patients with heart failure, stable angina, and several other conditions. Despite proven benefits in mortality rates, depression, functional capacity, and medication adherence, rates of referral for cardiac rehabilitation are suboptimal. Groups less likely to be referred are older adults, women, patients who do not speak English, and persons living in areas where cardiac rehabilitation is not locally available. Additionally, primary care physicians refer patients less often than cardiologists and cardiothoracic surgeons. PMID:27386722

    In 1997, two-thirds of the medical cost of diabetes was borne by the elderly and nursing home care attributable to diabetes accounted for a third of that financial burden. The development of the Insulin Delivery Pen system can provide cost efficiency, and concurrently reduce the potential for contamination, free up nursing time, improve the administration process, and maintain dosing accuracy. The insulin pen delivery system (vs. the traditional vial and syringe method) is an attractive and cost effective option in the treatment of diabetes mellitus for residents in nursing facilities.

    Background: Type II diabetes increases liver cancer risk but the risk may be mitigated by anti-diabetic medications. However, choice of medications is correlated with diabetes duration and severity, leading to confounding by indication. Methods: To address this association, we conducted a nested case–control study among persons with type II diabetes in the Clinical Practice Research Datalink. Cases had primary liver cancer and controls were matched on age, sex, practice, calendar time, and number of years in the database. Exposure was classified by type and combination of anti-diabetic prescribed and compared to non-use. Odds ratios (ORs) and 95% confidence intervals (95% CI) were calculated using conditional logistic regression. Results: In 305 cases of liver cancer and 1151 controls, there was no association between liver cancer and anti-diabetic medication use compared to non-use (OR=0.74 (95% CI=0.45–1.20) for metformin-only, 1.10 (95% CI=0.66–1.84) for other oral hypoglycaemic (OH)-only, 0.89 (95% CI=0.58–1.37) for metformin+other OH, 1.11 (95% CI=0.60–2.05) for metformin+insulin, 0.81 (95% CI=0.23–2.85) for other OH+insulin, and 0.72 (95% CI=0.18–2.84) for insulin-only). Stratification by duration of diabetes did not alter the results. Conclusions: Use of any anti-diabetic medications in patients with type II diabetes was not associated with liver cancer, though there was a suggestion of a small protective effect for metformin.

    Good management of diabetes can reduce the risk of complications of the disease. When not well managed, diabetes is associated with the complications of heart disease, stroke, blindness, kidney disease and amputations. Diabetes can reduce the blood supply to the feet and cause a loss of feeling. As a result, foot injuries do not heal well and the person may not realise that their foot is sore or injured. Damage to the foot may lead to the development of foot ulcers, which if left untreated may result in amputation of the limb. Preventive care is a priority, but when complications occur the next step is to halt progression. Therefore, effective foot care and timely treatment of foot ulcers are important in preserving foot function and mobility, and preventing amputation in adults with diabetes.

    This study examined diabetes-related health disparities in a Latino population in terms of prevalence of the disease, and the extent to which practice-based interventions improve health care and health for the Latinos who have diabetes. Previous research has shown that Latinos, overall, are at greater risk for diabetes, but less is known for those of Puerto Rican and Dominican origin. Two interventions were implemented in a large primary care practice: an ADA-recognized Diabetes Self Management Education program, and clinical information feedback loops to providers regarding adherence to the Massachusetts Guidelines for the Care of Diabetes. The study identified the prevalence of diabetes to be 13.7% among Puerto Ricans, and 9.1% among Dominicans, rates 2-to-3 times that for the general population. Latino patients (N=567) who participated in a Diabetes Self Management Education Program maintained lower Hb A1c values than did a comparison group (N=432). For a random sample of Latinos with diabetes (N=98) in this study, 6 measures of health care improved significantly from 2001 to 2003. Areas of improvement among healthcare providers were: ordering a microalbumin level measurement when appropriate, prescribing ACE inhibitors as needed, providing pneumococcal and influenza vaccines, reviewing activity status and exercise, identifying smoking status, and prescribing lipid-lowering agents, as appropriate. Body mass index (BMI) for the 98 patients remained the same for both measurement periods at 32.8. Although this initial study spanned only 2 years, improvements in health care and health indices for the population are encouraging. Further study is underway to expand on these gains.

    Common intestinal infections caused by human enteroviruses (HEVs) are considered major environmental factors predisposing to type 1 diabetes (T1D). In spite of the active research of the field, the HEV-induced pathogenetic processes are poorly understood. Recently, after the first documented report on HEV infections in the pancreatic islets of deceased T1D patients, several groups became interested in the issue and studied valuable human material, the autopsy pancreases of diabetic and/or autoantibody-positive patients for HEV infections. In this review, the data on HEV infections in human pancreatic islets are discussed with special reference to the methods used. Likewise, mechanisms that could increase viral access to the pancreas are reviewed and discussed.

    Aims/Introduction Muscle strength training has been suggested to improve glucose metabolism; however, epidemiological evidence regarding strength training's effects on diabetes risk is scarce. We prospectively examined the association between strength training and the risk of type 2 diabetes in Japanese men and women. Materials and Methods The sample included health checkups on 26,630 Japanese male and female workers aged 30–64 years without diabetes at baseline. Weekly time spent on strength training was elicited using a self-reported questionnaire. Type 2 diabetes was diagnosed based on hemoglobin A1c, fasting glucose, random plasma glucose and self-report in an annual health checkup. Hazard ratio (HR) and its 95% confidence interval (CI) for incident diabetes was estimated using a Cox proportional hazards model. Results During a mean follow up of 5.2 years with 139,748 person-years, 1,770 individuals developed diabetes. Age- and sex-adjusted HR for diabetes was 0.58 (95% CI 0.42–0.79) in those who engaged in strength training compared with those who engaged in no strength training. After further adjusting for potential confounders, the corresponding HR was 0.66 (95% CI 0.48–0.90). Additional adjustment for body mass index did not materially change the result; the HR was 0.70 (95% CI 0.51–0.96). The association was more pronounced in individuals aged 50 years or older than those aged <50 years, although the difference in the association by age was not significant. Conclusions These results suggest that engagement in strength training could help to reduce the risk of type 2 diabetes in a Japanese working population. PMID:26543539

    Objective Diabetes prevalence among ethnic minorities and immigrants often differs from the majority indigenous population. We compared diabetes prevalence, incidence and risk among Ethiopian and non-Ethiopian Jews. Within these main groups, we controlled for the effect of migration on diabetes risk by comparing the subgroups of Ethiopian and former Soviet Union (FSU) immigrants, and compared both with Israeli-born non-Ethiopian Jews. Methods The study cohort included adult Ethiopian (n = 8,398) and age-matched non-Ethiopian Jews (n = 15,977) and subgroups: Ethiopian immigrants (n = 7,994), FSU immigrants (n = 1,541) and Israeli-born non-Ethiopian Jews (n = 10,828). Diabetes prevalence, annual incidence, and hazard ratios (HRs) adjusted for sex and metabolic syndrome (MetS)-components, were determined in three age groups (<50yrs, 50-59yrs, and ≥60yrs). Comparisons of body mass index (BMI) at diabetes incidence were made. Results Younger (<50yrs) Ethiopians had higher prevalence rates, 3.6% (95%CI: 3.1–4.1) and annual incidence, 0.9% (95%CI: 0.8–1.0) than non-Ethiopians, 2.7% (95%CI: 2.3–3.0) and 0.5% (95%CI: 0.4–0.6), respectively. These differences were particularly pronounced among Ethiopian women. Diabetes risk among Ethiopians was higher and adjustment for MetS-components was important only for BMI, which further increased hazard ratio (HR) estimates associated with Ethiopian ethnicity from 1.81 (95% CI:1.50–2.17) to 2.31 (95% CI:1.91–2.79). The same differences were seen when comparing Ethiopian to FSU immigrants. BMI before incident diabetes was lower among younger Ethiopian immigrants than younger FSU immigrants and Israeli-born. Conclusions Ethiopian ethnicity is associated with increased diabetes risk, which is age and BMI dependent. Young Ethiopians<50yrs, particularly women, had the greatest increase in risk. Lower BMI cut-offs should be defined to reflect diabetes risk among Ethiopians. PMID:27300299

This study present a review of type 2 diabetes risk estimation mobile applications focusing on their functionality and availability of information on the underlying risk calculators. Only 9 out of 31 reviewed mobile applications, featured in three major mobile application stores, disclosed the name of risk calculator used for assessing the risk of type 2 diabetes. Even more concerning, none of the reviewed applications mentioned that they are collecting the data from users to improve the performance of their risk estimation calculators or offer users the descriptive statistics of the results from users that already used the application. For that purpose the questionnaires used for calculation of risk should be upgraded by including the information on the most recent blood sugar level measurements from users. Although mobile applications represent a great future potential for health applications, developers still do not put enough emphasis on informing the user of the underlying methods used to estimate the risk for a specific clinical condition.

    Although diabetes mellitus is associated with an increased risk of several malignancies, a negative association with prostate cancer is biologically most plausible. The epidemiologic evidence is, however, inconsistent, limited and based mostly on small studies. We present results from a large, population-based cohort study in Sweden, where we assessed prostate cancer risk among patients hospitalized for diabetes mellitus. The cohort was composed of patients identified in the Swedish In-Patient Register as having a hospital discharge diagnosis of diabetes mellitus in 1965-1994. The follow-up was done by linkages with the national cancer register and other population-based registers. Standardized incidence ratios (SIRs), with 95% confidence interval (CI), were used as a measure of relative risk. After complete exclusion of the first year of follow-up (to avoid selection bias), 135,950 men remained in the cohort, contributing 827,099 years of follow-up to the study. A total of 2,455 incident cases of primary prostate cancer were identified during 1-31 years of follow-up, yielding an overall SIR of 0.91 (95% CI 0.87-0.94); this risk reduction was more pronounced among patients who have been hospitalized for diabetic complications (SIR = 0.82; 95% CI 0.74-0.91). We found no consistent trends in risk related to age at first hospitalization or to duration of follow-up. We did find a small, but significantly decreased risk of prostate cancer among men who had been hospitalized for diabetes mellitus.

    Background The liver plays a key role in fuel metabolism. It is well established that liver disease is associated with an increased risk for diabetes mellitus. Hepatitis C virus infection has been known to increase the risk of diabetes. However, much less is known about the role of hepatitis B virus (HBV) infection in diabetes. We examined the association of diabetes based on the vaccination status for HBV. Methods In this cross-sectional study, we included adult subjects (≥20 y/o) with HBV serology available from the National Health and Nutrition Examination Survey 2005–2010. Diabetes was defined as established diabetes or fasting plasma glucose concentration ≥7.0 mmol/L, 2-hour plasma glucose concentration ≥11.1 mmol/L, or HbA1c ≥ 47.5 mmol/mol (6.5%). Vaccination was based on the reported history and immunization was determined by HBV serology. The odds ratio (OR) with 95% confidence intervals (95% CI) were calculated with consideration of the following covariates: age, gender, BMI, ethnic/racial group, current smoker, current alcohol consumption, family history of diabetes, poverty index, and education. Results This study included 15,316 subjects. Among them, 2,320 subjects was immunized based the HBV serology. Among 4,063 subjects who received HBV vaccination, successful vaccination was only noted in 39% of subjects. The HBV vaccination was not associated with diabetes (OR: 1.08, 95%CI: 0.96–1.23). Serology evidence of HBV immunization was associated with a reduced OR of diabetes (0.75, 95%CI: 0.62–0.90). Successful HBV vaccination was also associated with a reduced OR of diabetes (0.67, 95%CI: 0.52–0.84). Conclusions Although our study shows the association of HBV vaccination with the reduced odds of diabetes by 33%, a prospective study is warranted to confirm and examine the impact of HBV vaccination in prevention of diabetes.

    Diabetes is the fifth leading cause of death worldwide and contributes to leading causes of death, cancer and cardiovascular disease including coronary heart disease, stroke, peripheral vascular disease and other vascular disease. While glycemic management remains a cornerstone of diabetes care, the co-management of hypertension, atherosclerosis, cardiovascular risk reduction and prevention of long-term consequences associated with diabetes are now well recognized as essential to improve long-term survival. Clinical trial evidence substantiates the importance of glycemic control, LDL-cholesterol lowering therapy, blood-pressure lowering, control of albuminuria, and comprehensive approaches targeting multiple risk factors to reduce cardiovascular risk. This article presents a review of the role of diabetes in pathogenesis of atherosclerosis and cardiac dysfunction, recent evidence regarding degree of glycemic control and mortality, and available evidence for a multi-faceted approach to improve long-term outcomes for patients.

    Objectives To summarize data supporting the effects of antidiabetes agents on glucose control and cardiovascular risk factors in patients with type 2 diabetes. Methods Studies reporting on the effects of antidiabetes agents on glycemic control, body weight, lipid levels, and blood pressure parameters are reviewed and summarized for the purpose of selecting optimal therapeutic regimens for patients with type 2 diabetes. Results National guidelines recommend the aggressive management of cardiovascular risk factors in patients with type 2 diabetes, including weight loss and achieving lipid and blood pressure treatment goals. All antidiabetes pharmacotherapies lower glucose; however, effects on cardiovascular risk factors vary greatly among agents. While thiazolidinediones, sulfonylureas, and insulin are associated with weight gain, dipeptidyl peptidase-4 inhibitors are considered weight neutral and metformin can be weight neutral or associated with a small weight loss. Glucagon-like peptide-1 receptor agonists and amylinomimetics (e.g. pramlintide) result in weight loss. Additionally, metformin, thiazolidinediones, insulin, and glucagon-like peptide-1 receptor agonists have demonstrated beneficial effects on lipid and blood pressure parameters. Conclusion Management of the cardiovascular risk factors experienced by patients with type 2 diabetes requires a multidisciplinary approach with implementation of treatment strategies to achieve not only glycemic goals but to improve and/or correct the underlying cardiovascular risk factors.

    The aim of the study was to discuss the effect of intensive nursing education on the prevention of diabetic foot ulceration among patients at high risk for diabetic foot. One hundred eighty-five diabetes patients at high risk for foot diseases were enrolled in this study and provided with intensive nursing education, including individualized education about diabetes mellitus and diabetic foot diseases, instruction in podiatric care (the right way of washing the foot, the care of foot skin, appropriate choice of shoes and socks, intense examinations and records of feet by patients themselves every day, and the assistant management of calluses). Study subjects were followed up for 2 years. Once the foot ulceration developed, the inducing factors of foot ulceration were inquired about, the ulcers were evaluated, and the incidence of foot ulceration was analyzed before and after the intensive nursing education according to self-paired data. Results showed there were highly statistically significant improvements in the intensive treatment group compared with the control group in plasma glucose, blood pressure, and high-density lipoprotein cholesterol levels. More important is that intensive nursing education helps to prevent diabetic foot ulceration and to decrease the rate of amputation among patients at high risk for diabetic foot.

    Purpose Patients with low literacy, low numeracy, and/or linguistic needs can experience challenges understanding diabetes information and applying concepts to their self-management. The authors designed a toolkit of education materials that are sensitive to patients' literacy and numeracy levels, language preferences, and cultural norms and that encourage shared goal setting to improve diabetes self-management and health outcomes. The Partnership to Improve Diabetes Education (PRIDE) toolkit was developed to facilitate diabetes self-management education and support. Methods The PRIDE toolkit includes a comprehensive set of 30 interactive education modules in English and Spanish to support diabetes self-management activities. The toolkit builds upon the authors' previously validated Diabetes Literacy and Numeracy Education Toolkit (DLNET) by adding a focus on shared goal setting, addressing the needs of Spanish-speaking patients, and including a broader range of diabetes management topics. Each PRIDE module was evaluated using the Suitability Assessment of Materials (SAM) instrument to determine the material's cultural appropriateness and its sensitivity to the needs of patients with low literacy and low numeracy. Reading grade level was also assessed using the Automated Readability Index (ARI), Coleman-Liau, Flesch-Kincaid, Fry, and SMOG formulas. Conclusions The average reading grade level of the materials was 5.3 (SD 1.0), with a mean SAM of 91.2 (SD 5.4). All of the 30 modules received a “superior” score (SAM >70%) when evaluated by 2 independent raters. The PRIDE toolkit modules can be used by all members of a multidisciplinary team to assist patients with low literacy and low numeracy in managing their diabetes. PMID:26647414

    Cardiovascular disease (CVD) is the most frequent cause of death in people with type 1 diabetes (T1D), despite modern advances in glycemic control and CVD risk factor modification. CVD risk identification is essential in this high-risk population, yet remains poorly understood. This review discusses the risk factors for CVD in young people with T1D, including hyperglycemia, traditional CVD risk factors (dyslipidemia, smoking, physical activity, hypertension), as well as novel risk factors such as insulin resistance, inflammation, and hypoglycemia. We present evidence that adverse changes in cardiovascular function, arterial compliance, and atherosclerosis are present even during adolescence in people with T1D, highlighting the need for earlier intervention. The methods for investigating cardiovascular risk are discussed and reviewed. Finally, we discuss the observational studies and clinical trials which have thus far attempted to elucidate the best targets for early intervention in order to reduce the burden of CVD in people with T1D.

    The authors discuss the strategy of use of incretin hormones in type 2 diabetes treatment in the context of cardiovascular complications. The results of the phase III study on human GLP-1 (Glucagon-like peptide-1) analogue-liraglutide have been presented under common acronym LEAD (Liraglutide-Effect and Action In Diabetes). The liraglutide therapy improved glycemic control with low hypoglycemia risk and decreased glycated hemoglobin by an average 1,13%. Decreases in systolic pressure and significant body weight loss were observed. Not only did the index describing beta cells function HOMA-B improve but also did the ratio of insulin to proinsulin. Summing up, incretin hormones beneficially influence blood glucose level, moreover, their use decreases blood pressure and body weight which might indicate their positive influence on cardiovascular system in diabetic patients.

    Background Foot screening is an important part of diabetic care as it prevents significant morbidity, loss of function and mortality from diabetic foot complications. However, foot screening is often neglected. Aim This project was aimed at educating health care workers (HCWs) in a primary health care clinic to increase diabetic foot screening practices. Setting A primary health care clinic in the Western Cape province of South Africa Methods A quality improvement project was conducted. HCWs’ needs were assessed using a questionnaire. This was followed by focus group discussions with the HCWs, which were recorded, transcribed and assessed using a general inductive approach. An intervention was designed based on common themes. Staff members were trained on foot screening and patient information pamphlets and screening tools were made available to all clinic staff. Thirty-two consecutive diabetic patient folders were audited to compare screening in 2013 with that in 2014 after initiation of the quality improvement cycle. Results HCWs’ confidence in conducting foot screening using the diabetic foot assessment questionnaire improved markedly after training. Diabetic foot screening practices increased from 9% in 2013 to 69% in 2014 after the first quality improvement cycle. A strengths, opportunities, aspirations and results (SOAR) analysis showed promise for continuing quality improvement cycles. Conclusion The findings showed a significant improvement in the number of diabetic patients screened. Using strategic planning with appreciative intent based on SOAR, proved to be motivational and can be used in the planning of the next cycle. PMID:27608673

    Type 2 diabetes mellitus (T2DM) is a major and fast growing public health problem. Although obesity is considered to be the main driver of the pandemic of T2DM, a possible contribution of some environmental contaminants, of which persistent organic pollutants (POPs) form a particular class, has been suggested. POPs are organic compounds that are resistant to environmental degradation through chemical, biological, and photolytic processes which enable them to persist in the environment, to be capable of long-range transport, bio accumulate in human and animal tissue, bio accumulate in food chains, and to have potential significant impacts on human health and the environment. Several epidemiological studies have reported an association between persistent organic pollutants and diabetes risk. These findings have been replicated in experimental studies both in human (in-vitro) and animals (in-vivo and in-vitro), and patho-physiological derangements through which these pollutants exercise their harmful effect on diabetes risk postulated. This review summarizes available studies, emphasises on limitations so as to enable subsequent studies to be centralized on possible pathways and bring out clearly the role of POPs on diabetes risk.

    Type 2 diabetes mellitus (T2DM) is a global public health problem of epidemic proportions, with 60–70% of affected individuals suffering from associated neurovascular complications that act on multiple organ systems. The most common and clinically significant neuropathies of T2DM include uremic neuropathy, peripheral neuropathy, and cardiac autonomic neuropathy. These conditions seriously impact an individual’s quality of life and significantly increase the risk of morbidity and mortality. Although advances in gene sequencing technologies have identified several genetic variants that may regulate the development and progression of T2DM, little is known about whether or not the variants are involved in disease progression and how these genetic variants are associated with diabetic neuropathy specifically. Significant missing heritability data and complex disease etiologies remain to be explained. This article is the first to provide a review of the genetic risk variants implicated in the diabetic neuropathies and to highlight potential commonalities. We thereby aim to contribute to the creation of a genetic-metabolic model that will help to elucidate the cause of diabetic neuropathies, evaluate a patient’s risk profile, and ultimately facilitate preventative and targeted treatment for the individual.

    Exposure to ambient air pollution (AP) exposure has been linked to type 2 diabetes (T2D) risk. Evidence on the impact of T2D genetic variants on AP susceptibility is lacking. Compared to single variants, joint genetic variants contribute substantially to disease risk. We investigated the modification of AP and diabetes association by a genetic risk score (GRS) covering 63 T2D genes in 1524 first follow-up participants of the Swiss cohort study on air pollution and lung and heart diseases in adults. Genome-wide data and covariates were available from a nested asthma case-control study design. AP was estimated as 10-year mean residential particulate matter <10μm (PM10). We computed count-GRS and weighted-GRS, and applied PM10 interaction terms in mixed logistic regressions, on odds of diabetes. Analyses were stratified by pathways of diabetes pathology and by asthma status. Diabetes prevalence was 4.6% and mean exposure to PM10 was 22μg/m(3). Odds of diabetes increased by 8% (95% confidence interval: 2, 14%) per T2D risk allele and by 35% (-8, 97%) per 10μg/m(3) exposure to PM10. We observed a positive interaction between PM10 and count-GRS on diabetes [ORinteraction=1.10 (1.01, 1.20)], associations being strongest among participants at the highest quartile of count-GRS [OR: 1.97 (1.00, 3.87)]. Stronger interactions were observed with variants of the GRS involved in insulin resistance [(ORinteraction=1.22 (1.00, 1.50)] than with variants related to beta-cell function. Interactions with count-GRS were stronger among asthma cases. We observed similar results with weighted-GRS. Five single variants near GRB14, UBE2E2, PTPRD, VPS26A and KCNQ1 showed nominally significant interactions with PM10 (P<0.05). Our results suggest that genetic risk for T2D may modify susceptibility to air pollution through alterations in insulin sensitivity. These results need confirmation in diabetes cohort consortia.

    OBJECTIVE Antidepressant use has risen sharply over recent years. Recent concerns that antidepressants may adversely affect glucose metabolism require investigation. Our aim was to assess the risk of type 2 diabetes associated with antidepressants through a systematic review. RESEARCH DESIGN AND METHODS Data sources were MEDLINE, Embase, PsycINFO, The Cochrane Library, Web of Science, meeting abstracts of the European Association for the Study of Diabetes, American Diabetes Association, and Diabetes UK, Current Controlled Trials, ClinicalTrials.gov, U.K. Clinical Research Network, scrutiny of bibliographies of retrieved articles, and contact with relevant experts. Relevant studies of antidepressant effects were included. Key outcomes were diabetes incidence and change in blood glucose (fasting and random). RESULTS Three systemic reviews and 22 studies met the inclusion criteria. Research designs included 1 case series and 21 observational studies comprising 4 cross-sectional, 5 case-control, and 12 cohort studies. There was evidence that antidepressant use is associated with type 2 diabetes. Causality is not established, but rather, the picture is confused, with some antidepressants linked to worsening glucose control, particularly with higher doses and longer duration, others linked with improved control, and yet more with mixed results. The more recent, larger studies, however, suggest a modest effect. Study quality was variable. CONCLUSIONS Although evidence exists that antidepressant use may be an independent risk factor for type 2 diabetes, long-term prospective studies of the effects of individual antidepressants rather than class effects are required. Heightened alertness to potential risks is necessary until these are complete. PMID:24065841

    The success rate of organ transplantation has been increasing with advances in surgical and pharmacological techniques. However, the number of solid organ transplant recipients who require metabolic disease management is also growing. Post-transplant diabetes mellitus (PTDM) is a common complication after solid organ transplantation and is associated with risks of graft loss, cardiovascular morbidity, and mortality. Other risk factors for PTDM include older age, genetic background, obesity, hepatitis C virus infection, hypomagnesemia, and use of immunosuppressant agents (corticosteroids, calcineurin inhibitors, and mammalian target of rapamycin inhibitor). Management of PTDM should be started before the transplantation plan to properly screen high-risk patients. Even though PTDM management is similar to that of general type 2 diabetes, therapeutic approaches must be made with consideration of drug interactions between immunosuppressive agents, glucose-lowering medications, and graft rejection and function.

    Purpose Gestational diabetes mellitus (GDM) continues to be a significant health disorder triggering harmful complications in pregnant women and fetuses. Our knowledge of GDM epidemiology in Yemen is largely based on very limited data. The aim of this study was, therefore, to determine the prevalence and risk factors of GDM among pregnant women in Dhamar governorate, Yemen. Patients and methods A total of 311 subjects were randomly selected for this cross sectional survey. Health history data and blood samples were collected using a pretested questionnaire. To determine the prevalence of GDM, the fasting and random blood glucose techniques were applied according to the recommendations of the American Diabetes Association, using alternative methods that are more convenient to the targeted population. Poisson’s regression model incorporating robust sandwich variance was utilized to assess the association of potential risk factors in developing GDM. Results The prevalence of GDM was found to be 5.1% among the study population. Multivariate analysis confirmed age ≥30 years, previous GDM, family history of diabetes, and history of polycystic ovary syndrome as independent risk factors for GDM prevalence. However, body mass index ≥30 kg/m2 and previous macrosomic baby were found to be dependent risk factors. Conclusion This study reports new epidemiological information about the prevalence and risk factors of GDM in Yemen. Introduction of proper maternal and neonatal medical care and health education are important in order to save the mother and the baby. PMID:26869814

    OBJECTIVE To determine the prevalence of impaired fasting glucose (IFG) and undiagnosed and diagnosed diabetes in Thai adults in 2009 and examine the extent of changes in proportions of diagnosis, treatment, and control for blood glucose, high blood pressure, and high total cholesterol between 2004 and 2009. RESEARCH DESIGN AND METHODS Data from the multistage cross-sectional National Health Examination Survey (NHES) IV of 18,629 Thai adults aged ≥20 years conducted in 2009 were used to analyze and compare with the data from NHES III in 2004. RESULTS The prevalence of IFG and diabetes was 10.6 and 7.5%, respectively. Of all diabetes diagnoses, 35.4% were not previously diagnosed, and the proportion was higher in men than in women (47.3 vs. 23.4%, P < 0.05). Compared with those in year 2004, the proportions of individuals with diabetes and concomitant hypertension did not significantly decrease in 2009 in both sexes, but the proportions of women with diabetes who were abdominally obese or had high total cholesterol (≥5.2 mmol/L) significantly increased in 2009 by 18.0 and 23.5%, respectively (all P < 0.01). The rates of treatment and control of blood glucose, high blood pressure, and high total cholesterol were favorably improved in 2009. However, in substantial proportions of individuals with diabetes these concomitants were still controlled suboptimally. CONCLUSIONS The prevalence of diabetes and IFG remained high in Thai adults. Improvement in detection and control of diabetes and associated metabolic risk factors, particularly obesity and high serum cholesterol, are necessary. PMID:21816976

    AIM: To establish a link between the risk of diabetes with haemoglobinopathies by examining available evidence of the effects of iron and blood glucose homeostasis from molecular to epidemiological perspectives. METHODS: A systematic literature search was performed using electronic literature databases using various search terms. The International Diabetes Federation World Atlas was used to generate a list of populations with high rates of diabetes. PubMed, Scopus and Google Scholar were used to identify which of these populations also had a reported prevalence of haemoglobin abnormalities. RESULTS: Abnormalities in iron homeostasis leads to increases in reactive oxygen species in the blood. This promotes oxidative stress which contributes to peripheral resistance to insulin in two ways: (1) reduced insulin/insulin receptor interaction; and (2) β-cell dysfunction. Hepcidin is crucial in terms of maintaining appropriate amounts of iron in the body and is in turn affected by haemoglobinopathies. Hepcidin also has other metabolic effects in places such as the liver but so far the extent of these is not well understood. It does however directly control the levels of serum ferritin. High serum ferritin is found in obese patients and those with diabetes and a meta-analysis of the various studies shows that high serum ferritin does indeed increase diabetes risk. CONCLUSION: From an epidemiological standpoint, it is plausible that the well-documented protective effects of haemoglobinopathies with regard to malaria may have also offered other evolutionary advantages. By contributing to peripheral insulin resistance, haemoglobinopathies may have helped to sculpt the so-called “thrifty genotype”, which hypothetically is advantageous in times of famine. The prevalence data however is not extensive enough to provide concrete associations between diabetes and haemoglobinopathies - more precise studies are required. PMID:26788262

    The incidence of diabetes mellitus is increasing among companion animals. This disease has similar characteristics in both humans and animals. Diabetes is frequently identified as an independent risk factor for infections associated with increased mortality. In the present study, homozygous diabetic (db/db) mice were infected with Listeria (L.) monocytogenes and then treated with the anti-diabetic drug exendin-4, a glucagon-like peptide 1 analogue. In aged db/db mice, decreased CD11b+ macrophage populations with higher lipid content and lower phagocytic activity were observed. Exendin-4 lowered high lipid levels and enhanced phagocytosis in macrophages from db/db mice infected with L. monocytogenes. Exendin-4 also ameliorated obesity and hyperglycemia, and improved ex vivo bacteria clearance by macrophages in the animals. Liver histology examined during L. monocytogenes infection indicated that abscess formation was much milder in exendin-4-treated db/db mice than in the control animals. Moreover, mechanistic studies demonstrated that expression of ATP binding cassette transporter 1, a sterol transporter, was higher in macrophages isolated from the exendin-4-treated db/db mice. Overall, our results suggest that exendin-4 decreases the risk of infection in diabetic animals by modifying the interaction between intracellular lipids and phagocytic macrophages. PMID:23000581

    2015-06-01

    Diabetes is a common and rapidly growing disease that affects more than 380 million people worldwide and is an established risk factor for cardiovascular disease with differential effects on women compared to men. While the general population of women, particularly young women, has more favourable cardiovascular risk profiles than men, this protective effect has been shown to be lost or even reversed in diabetic women. Several studies have demonstrated a significant diabetes-associated excess risk of cardiovascular disease in women. Sex-specific differences in risk factors associated with diabetes and their management may be responsible for the relative excess cardiovascular risk in women with diabetes. Diabetic women need intensive treatment in order to optimize management of cardiovascular risk factors. Further studies are needed to elucidate the mechanisms underlying the excess cardiovascular risk in diabetic women in order to tailor prevention and treatment strategies.

    The rapidly increasing rates of obesity among women of childbearing age, not only in the United States but also across the globe, contribute to increased risks during pregnancy and childbirth. Overweight and obesity are quantified by body mass index (BMI) for clinical purposes. In 2010, 31.9% of U.S. women aged 20 to 39 years met the definition of obesity, a BMI of 30 kg/m or greater. Across the life span, obesity is associated with increased risks of hypertension, cardiovascular disease, diabetes, sleep apnea, and other diseases. During pregnancy, increasing levels of prepregnancy BMI are associated with increases in both maternal and fetal/neonatal risks. This article reviews current knowledge about obesity in pregnancy and health risks related to increased maternal BMI, addresses weight stigma as a barrier to care and interventions that have evidence of benefit, and discusses the development of policies and guidelines to improve care.

    In the USA, compared to whites, African-Americans are disproportionately impacted by the diabetes epidemic. Traditional diabetes risk factors, such as obesity, are more common among African-Americans, but these traditional risk factors do not explain all of the disparity in diabetes risk. Recent research has identified novel environmental, lifestyle, physiologic, and genetic risk factors for diabetes, some of which appear to impact African-Americans more than whites. This manuscript reviews the recent literature to highlight some of these novel risk factors that may be contributing to the racial disparity in diabetes risk. Further study is needed of the modifiable risk factors for development of interventions to reduce the risk of diabetes in African-Americans, as well as other high-risk populations.

    Summary Diabetes mellitus was identified as a risk factor for developing tuberculosis (TB) infection, and relapse after therapy. The risk of acquiring TB is described as comparable to that of HIV population. The fact that diabetics are 3× times more prone to develop pulmonary TB than nondiabetics cannot be overlooked. With DM recognized as global epidemic, and TB affecting one-third of the world population, physicians must remain vigilant. We present a 45-year-old woman born in Dominican Republic (DR), with 10-year history of T2DM treated with metformin, arrived to our Urgency Room complaining of dry cough for the past 3months. Interview unveiled unintentional 15lbs weight loss, night sweats, occasional unquantified fever, and general malaise but denied bloody sputum. She traveled to DR 2years before, with no known ill exposure. Physical examination showed a thin body habitus, otherwise well appearing woman with stable vital signs, presenting solely right middle lung field ronchi. LDH, ESR, hsCRP and Hg A1C were elevated. Imaging revealed a right middle lobe cavitation. Sputum for AFB disclosed active pulmonary TB. Our case portrays that the consideration of TB as differential diagnosis in diabetics should be exercised with the same strength, as it is undertaken during the evaluation of HIV patients with lung cavitation. Inability to recognize TB will endanger the patient, hospital dwellers and staff, and perpetuate this global public health menace. Learning points Diabetes mellitus should be considered an important risk factor for the reactivation of pulmonary tuberculosis. High clinical suspicious should be taken into consideration as radiological findings for pulmonary tuberculosis in patients with diabetes mellitus may be atypical, involving middle and lower lobes. Inability to recognize pulmonary tuberculosis will endanger the patient, hospital dwellers and staff, and perpetuate this global public health menace. PMID:27482384

    We conducted a case-control study to investigate the association between GSTM1, GSTT1 and GSTP1 IIe105Val polymorphisms and development of gestational diabetes mellitus in a Chinese population. A total of 320 patients with gestational diabetes mellitus and 358 pregnancy subjects were consecutively collected between January 2013 and December 2014. Genotyping for detection of GSTM1, GSTT1 and GSTP1 IIe105Val was conducted by using PCR-RFLP (polymerase chain reaction-restriction fragment length polymorphisms) method. By Fisher's exact test, we found that the genotype distributions of GSTP1 IIe105Val were in line with the Hardy-Weinberg equilibrium in control subjects (P=0.57). By Chi-square test, we found significant differences in the genotype distributions of GSTM1 (χ(2)=11.49, P=0.001) and GSTT1 (χ(2)=18.50, P<0.001). Using unconditional logistic analysis, individuals carrying the null genotypes of GSTM1 and GSTT1 were associated with an increased risk of gestational diabetes mellitus when compared with the present genotype, and the adjusted Ors (95% CI) were 1.71 (1.24-2.36) and 2.00 (1.44-2.79), respectively. However, the GSTP1 IIe105Val polymorphism was not associated with an elevated risk of gestational diabetes mellitus. In conclusion, we suggest that the GSTM1 null genotype and GSTT1 null genotype are correlated with an increased risk of gestational diabetes mellitus in a Chinese population.

    Purpose The purpose of this article was to summarize scientific knowledge from an expert panel on reproductive health among adolescents with type 2 diabetes (T2D). Methods Using a mental model approach, a panel of experts—representing perspectives on diabetes, adolescents, preconception counseling, and reproductive health—was convened to discuss reproductive health issues for female adolescents with T2D. Results Several critical issues emerged. Compared with adolescents with type 1 diabetes, (1) adolescents with T2D may perceive their disease as less severe and have less experience managing it, putting them at risk for complications; (2) T2D is more prevalent among African Americans, who may be less trusting of the medical establishment; (3) T2D is associated with obesity, and it is often difficult to change one’s lifestyle within family environments practicing sedentary and dietary behaviors leading to obesity; (4) teens with T2D could be more fertile, because obesity is related to earlier puberty; (5) although obese teens with T2D have a higher risk of polycystic ovary syndrome, which is associated with infertility, treatment with metformin can increase fertility; and (6) women with type 2 diabetes are routinely transferred to insulin before or during pregnancy to allow more intensive management. Conclusions Findings from the expert panel provide compelling reasons to provide early, developmentally appropriate, culturally sensitive preconception counseling for teens with T2D. PMID:20944055

    Introduction: Diabetes is a group of metabolic diseases characterized by hyperglycemia, and represents a disease of the modern age, disease of the 21st century. Prevention of this disease is listed as imperative. Aim of this article was to evaluate questionnaires on the assessment of risk factors for Diabetes Mellitus type 2. Material and Methods: A total of 540 questionnaires handed out randomly to citizens of Canton Sarajevo of all ages, sexes and educational levels (in January 2016) were analyzed. Results: Analyzed questionnaires showed relatively low risk of getting diabetes in the next ten years in the majority of the population. These results are rather encouraging but may in some way be in confrontation with the statistics which show a rapid outburst of diabetes. Conclusion: The life-style is the main reason for such a thing to happen, and looking at these questionnaires, we might get the feeling that we really do live in a, conditionally speaking, physically active society. That, from our everyday experience is not entirely true. It would be wise to continue doing research on this topic on the territory of Bosnia and Herzegovina. PMID:27482159

    Background Strong evidence supports that dietary modifications may decrease incident type 2 diabetes mellitus (T2DM). Numerous diabetes risk models/scores have been developed, but most do not rely specifically on dietary variables or do not fully capture the overall dietary pattern. We prospectively assessed the association of a dietary-based diabetes-risk score (DDS), which integrates optimal food patterns, with the risk of developing T2DM in the SUN (“Seguimiento Universidad de Navarra”) longitudinal study. Methods We assessed 17,292 participants initially free of diabetes, followed-up for a mean of 9.2 years. A validated 136-item FFQ was administered at baseline. Taking into account previous literature, the DDS positively weighted vegetables, fruit, whole cereals, nuts, coffee, low-fat dairy, fiber, PUFA, and alcohol in moderate amounts; while it negatively weighted red meat, processed meats and sugar-sweetened beverages. Energy-adjusted quintiles of each item (with exception of moderate alcohol consumption that received either 0 or 5 points) were used to build the DDS (maximum: 60 points). Incident T2DM was confirmed through additional detailed questionnaires and review of medical records of participants. We used Cox proportional hazards models adjusted for socio-demographic and anthropometric parameters, health-related habits, and clinical variables to estimate hazard ratios (HR) of T2DM. Results We observed 143 T2DM confirmed cases during follow-up. Better baseline conformity with the DDS was associated with lower incidence of T2DM (multivariable-adjusted HR for intermediate (25–39 points) vs. low (11–24) category 0.43 [95% confidence interval (CI) 0.21, 0.89]; and for high (40–60) vs. low category 0.32 [95% CI: 0.14, 0.69]; p for linear trend: 0.019). Conclusions The DDS, a simple score exclusively based on dietary components, showed a strong inverse association with incident T2DM. This score may be applicable in clinical practice to improve

    Background: The cytotoxic T lymphocyteassociated antigen 4 gene (CTLA-4) encode the T cell receptor involved in the control of T cell proliferation and mediates T cell apoptosis. The receptor protein is a specific T lymphocyte surface antigen that is detected on cells only after antigen presentation. Thus, CTLA-4 is directly involved in both immune and autoimmune responses and may be involved in the pathogenesis of multiple T cell-mediated autoimmune disorders. There is polymorphism at position 49 in exon 1 of the CTLA-4 gene, providing an A-G exchange. Moreover, we assessed the CTLA-4 49 (Thr/Ala) polymorphism in diabetic patients and first-degree relatives as compared to control subjects. Research design and methods: Three loci (HLA-DQB1, DQA1 and CTLA-4) were analysed in 62 type 1 diabetic patients, 72 firstdegree relatives and 84 nondiabetic control subjects by means of PCR-RFLP. Results: A significant enrichment in DQB1 alleles encoding for an amino acid different from Asp in position 57 (NA) and DQA1 alleles encoding for Arg in position 52 was observed in diabetic subjects and first-degree relatives as compared to controls. The genotype and allele frequencies of these polymorphisms in type 1 diabetic patients and firstdegree relatives differed significantly from those of controls (p< 0.001 and 0.05 respectively). CTLA-49 Ala alleles frequencies were 75.8% in type 1 diabetic patients and 68.1% in first-degree relatives in comparison to 35.7% in control subjects. The Ala/Ala genotype conferred a relative risk of 18.8 (p < 0.001). Conclusion: The CTLA-4 49 Ala allele confers an increased risk of type 1 diabetes, independent of age and HLA-DQ genetic markers.

    Diabetes affects more than 25% of Americans older than age 65 years. The medical care of older patients must differ from the care of their younger counterparts. Older patients are at high risk of drug toxicity. A hemoglobin A1c (HbA1c) level less than 7.0% has historically been the goal of all patients with diabetes, regardless of age. Recent research has demonstrated that using medications to achieve such tight glycemic control is not necessary and is often not safe.This article discusses the seminal research findings that strongly suggest that HbA1c goals should be relaxed in older patients. The authors then recommend an age-specific and functionally appropriate HbA1c reference range for patients receiving medications to improve glycemic control. Other interventions are suggested that should make diabetes care safer in older patients receiving hypoglycemic medications. PMID:27352408

    Recent studies in both humans and animals suggest that air pollution is an important risk factor for type 2 diabetes mellitus (T2DM). However, the mechanism by which air pollution mediates propensity to diabetes is not fully understood. While a number of epidemiologic studies have shown a positive association between ambient air pollution exposure and risk for T2DM, some studies have not found such a relationship. Experimental studies in susceptible disease models do support this association and suggest the involvement of tissues involved in the pathogenesis of T2DM such as the immune system, adipose, liver, and central nervous system. This review summarizes the epidemiologic and experimental evidence between ambient outdoor air pollution and T2DM.

    Background Cardiovascular disease risk increases when lipoprotein metabolism is dysfunctional. We have developed a computational model able to derive indicators of lipoprotein production, lipolysis, and uptake processes from a single lipoprotein profile measurement. This is the first study to investigate whether lipoprotein metabolism indicators can improve cardiovascular risk prediction and therapy management. Methods and Results We calculated lipoprotein metabolism indicators for 1981 subjects (145 cases, 1836 controls) from the Framingham Heart Study offspring cohort in which NMR lipoprotein profiles were measured. We applied a statistical learning algorithm using a support vector machine to select conventional risk factors and lipoprotein metabolism indicators that contributed to predicting risk for general cardiovascular disease. Risk prediction was quantified by the change in the Area-Under-the-ROC-Curve (ΔAUC) and by risk reclassification (Net Reclassification Improvement (NRI) and Integrated Discrimination Improvement (IDI)). Two VLDL lipoprotein metabolism indicators (VLDLE and VLDLH) improved cardiovascular risk prediction. We added these indicators to a multivariate model with the best performing conventional risk markers. Our method significantly improved both CVD prediction and risk reclassification. Conclusions Two calculated VLDL metabolism indicators significantly improved cardiovascular risk prediction. These indicators may help to reduce prescription of unnecessary cholesterol-lowering medication, reducing costs and possible side-effects. For clinical application, further validation is required.

    This study examined links among unrealistic optimism, sex, and risk perception of type 2 diabetes onset in college students. Participants included 660 college students who consented to complete a questionnaire. The results showed significant differences between students who perceived that they were at risk for type 2 diabetes onset and those who thought their peers were the ones at risk. A higher prevalence of participants thought their peers were the ones at risk for type 2 diabetes. Women were more likely than men to report a higher risk perception, indicating that their peers were at lower risk for diabetes onset. PMID:25717271

    OBJECTIVES To estimate risk of comorbid depression on all-cause mortality over time among individuals with diabetes METHODS Medline, CINAHL, Cochrane Library, Embase, and Science Direct database were searched through September. 30, 2012. We limited our search to longitudinal or prospective studies reporting all-cause mortality among those having depression and diabetes, compared with those having diabetes alone that used hazard ratios as the main outcome. Two reviewers independently extracted primary data and evaluated quality of studies using predetermined criteria. The pooled random effects adjusted hazard ratios (HRs) were estimated using meta-analysis. The impact of moderator variables on study effect size was examined with meta-regression. RESULTS A total of 42,363 respondents from 10 studies were included in the analysis. Depression was significantly associated with risk of mortality (Pooled HRs: 1.50, 95% CI: 1.35, 1.66). Little evidence for heterogeneity was found across the studies (Cochran Q: 13.52, p-value: 0.20, I2: 26.03). No significant possibility of publication bias was detected (Egger’s regression intercept: 0.98, p-value: 0.23). CONCLUSION Depression significantly increases the risk of mortality among individuals with diabetes. Early detection and treatment of depression may improve health outcomes in this population.

    This project utilized a cross-sectional study design to assess diabetes risk among 540 individuals from 12 counties using trained extension agents and community organizations in West Virginia. Individuals were screened for diabetes using (1) the validated 7-item diabetes risk assessment survey and (2) hemoglobin A1c tests. Demographic and lifestyle behaviors were also collected. The average age, body mass index, and A1c were 51.2 ± 16.4, 31.1 ± 7.5, and 5.8 ± 0.74, respectively. The majority were females, Non-Hispanic Whites with no prior diagnosis of diabetes. Screenings showed that 61.8% of participants were at high risk for diabetes. Family history of diabetes (siblings or parents), overweight or obese status, sedentary lifestyle, and older age were commonly prevalent risk factors. Higher risk scores computed from the 7-item questions correlated positively with higher A1c (r = 0.221, P < 0.001). In multivariate logistic regression analyses, higher diabetes risk was predicted by obesity, older age, family history of hypertension, and gestational diabetes. Females were 4 times at higher risk than males. The findings indicated that community-based screenings were an effective way to assess diabetes risk in rural West Virginia. Linking diabetes screenings with referrals to lifestyle programs for high risk individuals can help reduce the burden of diabetes in the state. PMID:26881242

  13. High-sensitivity C-reactive protein as cardiovascular risk marker in patients with diabetes mellitus.

    PubMed

    Pfützner, Andreas; Forst, Thomas

    2006-02-01

    C-reactive protein (CRP) is a liver-derived pattern recognition molecule that is increased in inflammatory states. It rapidly increases within hours after tissue injury, and it is suggested that it is part of the innate immune system and contributes to host defense. Since cardiovascular disease is at least in part an inflammatory process, CRP has been investigated in the context of arteriosclerosis and subsequent vascular disorders. Based on multiple epidemiological and intervention studies, minor CRP elevation [high-sensitivity CRP (hsCRP)] has been shown to be associated with future major cardiovascular risk (hsCRP:<1 mg/L=low risk; 1-3 mg/L=intermediate risk; 3-10 mg/L=high risk; >10 mg/L=unspecific elevation). It is recommended by the American Heart Association that patients at intermediate or high risk of coronary heart disease may benefit from measurement of hsCRP with regard to their individual risk prediction. Elevation of hsCRP is associated with increased risk of type 2 diabetes development in patients with all levels of metabolic syndrome. In type 1 and type 2 diabetes mellitus, hemoglobin A1c significantly correlates with hsCRP levels and future cardiovascular risk. Also, hsCRP levels increase with the stage of beta-cell dysfunction and insulin resistance. Non-diabetes drugs that have been shown to reduce hsCRP concentrations include aspirin, statins, cyclooxygenase-2 inhibitors, and fibrates. Recent intervention studies have also demonstrated the distinct efficacy of different anti-diabetes treatments on a variety of cardiovascular risk markers. Intensive insulin therapy may reduce inflammation, but this effect may be influenced by the degree of weight gain. Treatment with peroxisome proliferator-activated receptor gamma has lead to substantial reduction of hsCRP and other cardiovascular risk markers in several comparator studies. Since this effect was shown to be independent of the degree of glycemic improvement, it can be regarded as a classspecific

    Methodologic biases may explain why observational studies examining metformin use in relation to lung cancer risk have produced inconsistent results. We conducted a cohort study to further investigate this relationship, accounting for potential biases. For 47,351 patients with diabetes aged ≥40 years, who completed a health-related survey administered between 1994 and 1996, data on prescribed diabetes medications were obtained from electronic pharmacy records. Follow-up for incident lung cancer occurred from January 1, 1997, until June 30, 2012. Using Cox regression, we estimated lung cancer risk associated with new use of metformin, along with total duration, recency, and cumulative dose (all modeled as time-dependent covariates), adjusting for potential confounding factors. During 428,557 person-years of follow-up, 747 patients were diagnosed with lung cancer. No association was found with duration, dose, or recency of metformin use and overall lung cancer risk. Among never smokers, however, ever use was inversely associated with lung cancer risk (hazard ratio (HR) 0.57; 95% confidence interval (CI), 0.33-0.99), and risk appeared to decrease monotonically with longer use (≥5 years: HR, 0.48; 95% CI, 0.21-1.09). Among current smokers, corresponding risk estimates were >1.0, although not statistically significant. Consistent with this variation in effect by smoking history, longer use was suggestively associated with lower adenocarcinoma risk (HR, 0.69; 95% CI, 0.40-1.17), but higher small cell carcinoma risk (HR, 1.82; 95% CI, 0.85-3.91). In this population, we found no evidence that metformin use affects overall lung cancer risk. The observed variation in association by smoking history and histology requires further confirmation.

    Diabetic nephropathy is a major cause of morbidity and mortality in diabetic patients. Effective therapies to prevent the development of this disease are required. Berberine (BBR) has several preventive effects on diabetes and its complications. However, the molecular mechanism of BBR on kidney function in diabetes is not well defined. Here, we reported that activation of AMP-activated protein kinase (AMPK) is required for BBR-induced improvement of kidney function in vivo. AMPK phosphorylation and activity, productions of reactive oxygen species (ROS), kidney function including serum blood urea nitrogen (BUN), creatinine clearance (Ccr), and urinary protein excretion, morphology of glomerulus were determined in vitro or in vivo. Exposure of cultured human glomerulus mesangial cells (HGMCs) to BBR time- or dose-dependently activates AMPK by increasing the thr172 phosphorylation and its activities. Inhibition of LKB1 by siRNA or mutant abolished BBR-induced AMPK activation. Incubation of cells with high glucose (HG, 30 mM) markedly induced the oxidative stress of HGMCs, which were abolished by 5-aminoimidazole-4-carboxamide ribonucleoside, AMPK gene overexpression or BBR. Importantly, the effects induced by BBR were bypassed by AMPK siRNA transfection in HG-treated HGMCs. In animal studies, streptozotocin-induced hyperglycemia dramatically promoted glomerulosclerosis and impaired kidney function by increasing serum BUN, urinary protein excretion, and decreasing Ccr, as well as increased oxidative stress. Administration of BBR remarkably improved kidney function in wildtype mice but not in AMPKα2-deficient mice. We conclude that AMPK activation is required for BBR to improve kidney function in diabetic mice. PMID:25409232

    2010-01-01

    BACKGROUND We examined the effects of a multicomponent, school-based program addressing risk factors for diabetes among children whose race or ethnic group and socioeconomic status placed them at high risk for obesity and type 2 diabetes. METHODS Using a cluster design, we randomly assigned 42 schools to either a multicomponent school-based intervention (21 schools) or assessment only (control, 21 schools). A total of 4603 students participated (mean [±SD] age, 11.3±0.6 years; 54.2% Hispanic and 18.0% black; 52.7% girls). At the beginning of 6th grade and the end of 8th grade, students underwent measurements of body-mass index (BMI), waist circumference, and fasting glucose and insulin levels. RESULTS There was a decrease in the primary outcome — the combined prevalence of overweight and obesity — in both the intervention and control schools, with no significant difference between the school groups. The intervention schools had greater reductions in the secondary outcomes of BMI z score, percentage of students with waist circumference at or above the 90th percentile, fasting insulin levels (P = 0.04 for all comparisons), and prevalence of obesity (P = 0.05). Similar findings were observed among students who were at or above the 85th percentile for BMI at baseline. Less than 3% of the students who were screened had an adverse event; the proportions were nearly equivalent in the intervention and control schools. CONCLUSIONS Our comprehensive school-based program did not result in greater decreases in the combined prevalence of overweight and obesity than those that occurred in control schools. However, the intervention did result in significantly greater reductions in various indexes of adiposity. These changes may reduce the risk of childhood-onset type 2 diabetes.

    Human parechoviruses (HPeVs) are RNA viruses associated mainly with mild gastrointestinal and respiratory infections in children and also cause neonatal sepsis and CNS infections. Human enteroviruses, close relatives of HPeVs, associate with the development of type 1 diabetes. In this study, the potential role of HPeV infections in promoting beta cell autoimmunity was investigated by analyzing stool samples of 54 prediabetic case and 134 healthy control children for the presence of HPeV RNA and comparing the derived infection frequencies. All 188 children were participants of the Finnish prospective Diabetes Prediction and Prevention study. Viral RNA was screened for using an HPeV-specific RT-PCR method coupled to liquid hybridization of the PCR product. The overall HPeV infection frequency did not differ between prediabetic case and control children. However, case boys had more HPeV positive samples in the 6-month period before becoming autoantibody positive, when compared to the matching time-period in controls (P < 0.01). HPeV infection at a young age does not appear to play a major role in the development of beta-cell autoimmunity. In boys, however, HPeVs showed time-dependent association with the first detection of diabetes-associated autoantibodies. Thus, in boys, HPeV infections cannot be excluded as a gender-specific risk factor which promotes the development of type 1 diabetes. PMID:23852688

    The incidence of both type 1 and type 2 diabetes is increasing globally, most likely explained by environmental changes, such as changing exposures to foods, viruses, and toxins, and by increasing obesity. While cardiovascular disease (CVD) mortality has been declining recently, this global epidemic of diabetes threatens to stall this trend. CVD is the leading cause of death in both type 1 and type 2 diabetes, with at least a two- to fourfold increased risk in patients with diabetes. In this review, the risk factors for CVD are discussed in the context of type 1 and type 2 diabetes. While traditional risk factors such as dyslipidemia, hypertension, and obesity are greater in type 2 patients than in type 1 diabetes, they explain only about half of the increased CVD risk. The role for diabetes-specific risk factors, including hyperglycemia and kidney complications, is discussed in the context of new study findings. PMID:23519720

    AIM To investigate the prevalence and risk factors of diabetic retinopathy (DR) in northern Chinese patients with type 2 diabetes mellitus (T2DM). METHODS This retrospective cross-sectional study was performed between May 2011 and April 2012. A total of 1100 patients (male/female, 483/617) were included in this study. DR was defined following the Early Treatment Diabetic Retinopathy Study (ETDRS) severity scale. All included patients accepted a comprehensive ophthalmic examination including retinal photographs. Logistic regression models were used to estimate odds ratios (ORs) and 95% confidence interval (CI) after adjusting for age and gender. RESULTS Retinopathy was present in 307 patients with a prevalence of 27.9%. In univariate logistic analysis, presence of DR was associated with longer duration of diabetes (OR, 5.70; 95%CI, 2.91-12.56), higher concentration of fasting blood glucose (OR, 12.94; 95%CI, 2.40-67.71), higher level of glycosylated hemoglobin HbA1c (OR, 5.50; 95%CI, 3.78-11.97) and insulin treatment (OR, 6.99; 95%CI, 1.39-35.12). The lifestyle of patients with T2DM including smoking, alcohol consumption and regular exercise seemed not associated with the development of DR. CONCLUSION Our study suggests that fasting serum glucose concentration, HbA1c level, duration of diabetes and insulin treatment are potential risk factors for DR in northern Chinese patients with T2DM, while the lifestyle of included patients seems not associated with DR.

    The pathophysiological backgrounds as well as clinical phenotypes of Japanese or East Asian patients with type 2 diabetes are quite different from those in Western countries. According to results of East Asian large-scale studies such as the Japan Diabetes Complications Study (JDCS), which is a representative cohort of Japanese patients with type 2 diabetes, Japanese patients had a much lower body mass index and lower incidence of coronary heart disease compared with Caucasian diabetic patients. Other differences between Japanese and Caucasian patients with type 2 diabetes could be found in risk factors such as fruit intake on retinopathy and significance of triglycerides, or the effects of moderate alcohol drinking on cardiovascular disease. These results demonstrated a necessity of ethnic group-specific risk evaluations and care of type 2 diabetes and its complications.

    Recent trials of intensive glycemic control suggest a possible link between hypoglycemia and excess cardiovascular mortality in patients with type 2 diabetes. Hypoglycemia might cause arrhythmias through effects on cardiac repolarization and changes in cardiac autonomic activity. Our aim was to study the risk of arrhythmias during spontaneous hypoglycemia in type 2 diabetic patients with cardiovascular risk. Twenty-five insulin-treated patients with type 2 diabetes and a history of cardiovascular disease or two or more risk factors underwent simultaneous continuous interstitial glucose and ambulatory electrocardiogram monitoring. Frequency of arrhythmias, heart rate variability, and markers of cardiac repolarization were compared between hypoglycemia and euglycemia and between hyperglycemia and euglycemia matched for time of day. There were 134 h of recording at hypoglycemia, 65 h at hyperglycemia, and 1,258 h at euglycemia. Bradycardia and atrial and ventricular ectopic counts were significantly higher during nocturnal hypoglycemia compared with euglycemia. Arrhythmias were more frequent during nocturnal versus daytime hypoglycemia. Excessive compensatory vagal activation after the counterregulatory phase may account for bradycardia and associated arrhythmias. QT intervals, corrected for heart rate, >500 ms and abnormal T-wave morphology were observed during hypoglycemia in some participants. Hypoglycemia, frequently asymptomatic and prolonged, may increase the risk of arrhythmias in patients with type 2 diabetes and high cardiovascular risk. This is a plausible mechanism that could contribute to increased cardiovascular mortality during intensive glycemic therapy.

    Objectives. To review the contribution of the Nurses’ Health Study (NHS) and the NHS II to addressing hypotheses regarding risk factors for type 2 diabetes. Methods. We carried out a narrative review of 1976 to 2016 NHS and NHS II publications. Results. The NHS and NHS II have uncovered important roles in type 2 diabetes for individual nutrients, foods, dietary patterns, and physical activity independent of excess body weight. Up to 90% of type 2 diabetes cases are potentially preventable if individuals follow a healthy diet and lifestyle. The NHS investigations have also identified novel biomarkers for diabetes, including adipokines, inflammatory cytokines, nutrition metabolites, and environmental pollutants, offering new insights into the pathophysiology of the disease. Global collaborative efforts have uncovered many common genetic variants associated with type 2 diabetes and improved our understanding of gene–environment interactions. Continued efforts to identify epigenetic, metagenomic, and metabolomic risk factors for type 2 diabetes have the potential to reveal new pathways and improve prediction and prevention. Conclusions. Over the past several decades, the NHS and NHS II have made major contributions to public health recommendations and strategies designed to reduce the global burden of diabetes. PMID:27459454

    Self-management of diabetes is essential to reducing the risks of associated disabilities. But effective self-management is often short-lived. Peers can provide the kind of ongoing support that is needed for sustained self-management of diabetes. In this context, peers are nonprofessionals who have diabetes or close familiarity with its management. Key functions of effective peer support include assistance in daily management, social and emotional support, linkage to clinical care, and ongoing availability of support. Using these four functions as a template of peer support, project teams in Cameroon, South Africa, Thailand, and Uganda developed and then evaluated peer support interventions for adults with diabetes. Our initial assessment found improvements in symptom management, diet, blood pressure, body mass index, and blood sugar levels for many of those taking part in the programs. For policy makers, the broader message is that by emphasizing the four key peer support functions, diabetes management programs can be successfully introduced across varied cultural settings and within diverse health systems.

    Diabetic retinopathy affects 4.2 million people in the United States and is the leading cause of blindness in working-aged people. As the prevalence of diabetes continues to rise, cost-effective interventions to decrease blindness from diabetic retinopathy will be paramount. While HbA1c and duration of disease are known risk factors, they account for only 11% of the risk of developing microvascular complications from the disease. The assessment of environmental risk factors for diabetic eye disease allows for the determination of modifiable population-level challenges that may be addressed to facilitate the end of blindness from diabetes.

    Aims. To apply and assess the suitability of a model consisting of commonly used cross-cultural translation methods to achieve a conceptually equivalent Gujarati language version of the Leicester self-assessment type 2 diabetes risk score. Methods. Implementation of the model involved multiple stages, including pretesting of the translated risk score by conducting semistructured interviews with a purposive sample of volunteers. Interviews were conducted on an iterative basis to enable findings to inform translation revisions and to elicit volunteers' ability to self-complete and understand the risk score. Results. The pretest stage was an essential component involving recruitment of a diverse sample of 18 Gujarati volunteers, many of whom gave detailed suggestions for improving the instructions for the calculation of the risk score and BMI table. Volunteers found the standard and level of Gujarati accessible and helpful in understanding the concept of risk, although many of the volunteers struggled to calculate their BMI. Conclusions. This is the first time that a multicomponent translation model has been applied to the translation of a type 2 diabetes risk score into another language. This project provides an invaluable opportunity to share learning about the transferability of this model for translation of self-completed risk scores in other health conditions. PMID:27703985

    Diabetics are regarded a special category of patients known to experience higher rates of cardiovascular complications as compared to the non-diabetic ones. Despite substantial efforts to minimize these risks, with aggressive antiplatelet and lipid lowering therapy, some of the diabetic patients still have a considerable residual risk for cardiovascular adverse events. Important preclinical data with potent lipid-lowering agents, like fibrates, omega-3-fatty acids, and niacin, have shown that they can provide sufficient help in reducing rates of cardiovascular events. In the present review, we are aim to explain their basic mechanisms of action, to present all the available clinical data regarding the efficacy of those agents, and to identify specific diabetic patients' subsets, in whom supplementary therapy with those agents could provide substantial benefit in terms of clinical outcome and not only lipid profile improvement.

    Hypoglycaemia and its consequences represent a significant risk for many people who have type 2 diabetes, and hypoglycaemia is currently under-recognised and commonly avoidable. Current clinical guidelines recommend the targeting of tight glycaemic control and this strategy may also be associated with an increased risk of hypoglycaemia. Hypoglycaemia impacts on morbidity, mortality and quality of life of people with type 2 diabetes, and improved recognition of the symptoms of hypoglycaemia will allow effective treatment and reduce the risk of progression to more severe episodes. A common cause of hypoglycaemia in people with type 2 diabetes is glucose-lowering medication, in particular, those which raise insulin independently of ambient glucose concentration such as sulphonylureas and exogenous insulin. The recently published National Institute for Health and Clinical Excellence guideline recommends the use of Dipeptidyl peptidase-4 inhibitors or thiazolidinediones (glitazones) as alternative second-line therapy instead of a sulphonylurea in those patients who are at significant risk of hypoglycaemia and its consequences.

    Background: To determine the prevalence of diabetes and pre-diabetes and to assess the risk factors associated with diabetes and pre-diabetes in the urban slums of Bangalore. Materials and Methods: A cross-sectional study was conducted in four slums of Bangalore in the age group of 35 years and above comprising of total 2013 subjects. Risk factors like age, sex, family history, behavior, physical activity, BMI, waist hip ration, diet habits were assessed to find their association with diabetes. Results: Prevalence of diabetes was 12.33% and of pre-diabetes was 11.57%. Prevalence was more among the females compared to males. Increasing age, over weight and obesity, sedentary life style, tobacco consumption, diet habits showed statistically significant association with prevalence of diabetes and pre-diabetes. Conclusion: Physical activity like regular exercises both at the office and at home, fibers-rich diet, blood sugar estimation after 35 years are some of the recommendations which can control diabetes.

    The anti-diabetic potential of Petalonia binghamiae extract (PBE) was evaluated in vivo. Dietary administration of PBE to streptozotocin (STZ)-induced diabetic mice significantly lowered blood glucose levels and improved glucose tolerance. The mode of action by which PBE attenuated diabetes was investigated in vitro using 3T3-L1 cells. PBE treatment stimulated 3T3-L1 adipocyte differentiation as evidenced by increased triglyceride accumulation. At the molecular level, peroxisome proliferator-activated receptor {gamma} (PPAR{gamma}) and terminal marker protein aP2, as well as the mRNA of GLUT4 were up-regulated by PBE. In mature adipocytes, PBE significantly stimulated the uptake of glucose and the expression of insulin receptor substrate-1 (IRS-1). Furthermore, PBE increased PPAR{gamma} luciferase reporter gene activity in COS-1 cells. Taken together, these results suggest that the in vivo anti-diabetic effect of PBE is mediated by both insulin-like and insulin-sensitizing actions in adipocytes.

    Morbidity and mortality associated with diabetes make it a prime target for quality improvement research. Quality gaps and racial/gender disparities persist throughout this population of patients necessitating a sustainable improvement in the clinical management of diabetes. The authors of this study sought (1) to provide a population perspective on diabetes management, and (2) to reinforce evidence-based clinical guidelines through a Web-based educational module.The project also aimed to gain insight into working remotely with a community of rural physicians. This longitudinal pre-post intervention study involved 18 internal medicine physicians and included 3 points of medical record data abstraction over 24 months. A Web-based educational module was introduced after the baseline data abstraction. This module contained chapters on clinical education, practice tools, and self-assessment. The results showed a sustained improvement in most clinical outcomes and demonstrated the effectiveness of using Web-based mediums to reinforce clinical guidelines and change physician behavior.

  15. Commentary: improving persistently elevated HbA1c in diabetes mellitus patients in Nigeria.

    Glycated hemoglobin (HbA1c) level in patients with diabetes reflects quality of disease control and propensity to develop hyperglycemic complications. During more than 12 years of using HbA1c for monitoring of glycemic control among patients at Nigerian hospitals, the mean glycated hemoglobin ranged from 7.9% ± 2.4 to 8.3% ± 2.2. Most of these patients (63% to 68%) had poor glycemic controls with mean HbA1c greater than 7%. Factors that are implicated in this scenario are: 1) high cost of HbA1c testing, 2) ineffective management of risk factors, 3) poor patient compliance, 4) improperly managed diabetes education program, and 5) health care system defect. Central to improving diabetes glycemia is education of doctors, other health workers and patients, within the confines of an overhauled national health system. Physicians need to increase adherence to diabetes mellitus management guidelines and patients must be enrolled into a well-structured education program at health centers. Doctors, as leader of the health team, should drive such education schemes, which must be based on standard training curriculum, sufficient number of trained diabetes educators, and effective monitoring of patients. The most appropriate diabetes education model features small-to-moderate sized participant groups and makes use of motivational interviewing rather than a traditional advice-giving format. Improved health care funding is mandatory given the issue of cost and this can be helped by increased participation of patients in Nigeria's National Health Insurance Scheme. Failure to address the persistently elevated HbA1c will affect long-term quality of life, longevity and health care services in Nigeria.

    HIV infection and its treatment have been associated with adipose tissue changes and disorders of glucose and lipid metabolism. The proportion of HIV-infected adults over the age of 50 is also growing placing HIV-infected adults at particular risk for metabolic perturbations and cardiovascular disease. The metabolic syndrome in HIV-infected adults has been increasingly studied but whether HIV is associated with greater risk remains unclear, likely because of the interplay of host, viral and antiretroviral factors that are associated with the components of the metabolic syndrome. While the Framingham Risk Score is a well-accepted measure of 10-year cardiovascular risk in the general population, it may not accurately predict risk in the HIV setting due to HIV-related factors such as inflammation that are not accounted for. The relationship between HIV and diabetes mellitus (DM) risk has also been debated. We summarize the recent literature on metabolic syndrome, DM, and cardiovascular risk in HIV-infected adults.

    Resveratrol is a natural polyphenolic compound that activates nicotinamide adenosine dinucleotide-dependent deacetylase SIRT1. Resveratrol has recently been shown to exert potent antidiabetic actions when orally delivered to animal models of type 2 diabetes. However, the tissue(s) mediating these beneficial effects is unknown. Because SIRT1 is expressed in central nervous system (CNS) neurons known to control glucose and insulin homeostasis, we hypothesized that resveratrol antidiabetic effects are mediated by the brain. Here, we report that long-term intracerebroventricular infusion of resveratrol normalizes hyperglycemia and greatly improves hyperinsulinemia in diet-induced obese and diabetic mice. It is noteworthy that these effects are independent of changes in body weight, food intake, and circulating leptin levels. In addition, CNS resveratrol delivery improves hypothalamic nuclear factor-κB inflammatory signaling by reducing acetylated-RelA/p65 and total RelA/p65 protein contents, and inhibitor of nuclear factor-κB α and IκB kinase β mRNA levels. Furthermore, this treatment leads to reduced hepatic phosphoenolpyruvate carboxykinase 1 mRNA and protein levels and ameliorates pyruvate-induced hyperglycemia in this mouse model of type 2 diabetes. Collectively, our results unveiled a previously unrecognized key role for the CNS in mediating the antidiabetic actions of resveratrol. PMID:19819963

    The content of glycated hemoglobin, a biomarker of diabetes in patients with type 2 diabetes correlates with risk factors for cardiovascular disease: hypertension, BMI and ratio of total cholesterol to HDL cholesterol. Therefore, increase in glycosylated hemoglobin should be considered a predictor of cardiovascular disease in patients with type 2 diabetes.

    Several limitations existed in previous studies which suggested that diabetic patients have increased risk of stroke. We conducted this study to better understand the stroke risk and poststroke outcomes in patients with diabetes.From the claims data of Taiwan's National Health Insurance, we identified 24,027 adults with new-diagnosed diabetes and 96,108 adults without diabetes between 2000 and 2003 in a retrospective cohort study. Stroke events (included hemorrhage, ischemia, and other type of stroke) during the follow-up period of 2000 to 2008 were ascertained and adjusted risk of stroke associated with diabetes was calculated. A nested cohort study of 221,254 hospitalized stroke patients (included hemorrhage, ischemia, and other type of stroke) between 2000 and 2009 was conducted. Adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were calculated for adverse events after stroke hospitalization in patients with and without diabetes.The incidences of stroke in cohorts with and without diabetes were 10.1 and 4.5 per 1000 person-years, respectively. During the follow-up period, diabetic patients had an increased risk of stroke (adjusted hazard ratio: 1.75; 95% CI: 1.64-1.86) than those without diabetes. Associations between diabetes and stroke risk were significant in both sexes and all age groups. Previous diabetes was associated with poststroke mortality (OR: 1.33; 95% CI: 1.19-1.49), pneumonia (OR: 1.30; 95% CI: 1.20-1.42), and urinary tract infection (OR: 1.66; 95% CI: 1.55-1.77). The impact of diabetes on adverse events after stroke was investigated particularly in those with diabetes-related complications.Diabetes was associated with stroke risk, and diabetic patients had more adverse events and subsequent mortality after stroke.

    Background To determine rates of diabetes, hypertension, and hyperlipidemia in Cambodian refugees, and to assess the proportion whose conditions are satisfactorily managed in comparison to the general population. Methods Self-report and laboratory/physical health assessment data obtained from a household probability sample of U.S.-residing Cambodian refugees (N = 331) in 2010-2011 were compared to a probability sample of the adult U.S. population (N = 6360) from the 2009-2010 National Health and Nutrition Examination Survey. Results Prevalence of diabetes, hypertension and hyperlipidemia in Cambodian refugees greatly exceeded rates found in the age- and gender-adjusted U.S. population. Cambodian refugees with diagnosed hypertension or hyperlipidemia were less likely than their counterparts in the general U.S. population to have blood pressure and total cholesterol within recommended levels. Conclusions Increased attention should be paid to prevention and management of diabetes and cardiovascular disease risk factors in the Cambodian refugee community. Research is needed to determine whether this pattern extends to other refugee groups. PMID:25651882

    The association between BMI and amputation risk is not currently well known. We used data for a cohort of diabetic patients treated in the US Department of Veterans Affairs Healthcare System in 2003. Men aged <65 years at the end of follow-up were examined for their amputation risk and amputation-free survival during the next 5 years (2004-2008). Compared to overweight individuals (BMI 25-29.9 kg/m(2)), the risks of amputation and treatment failure (amputation or death) were higher for patients with BMI <25 kg/m(2) and were lower for those with BMI ≥30 kg/m(2). Individuals with BMI ≥40 kg/m(2) were only half as likely to experience any (hazard ratios (HR) = 0.49; 95% confidence interval (CI), 0.30-0.80) and major amputations (HR = 0.53; 95% CI, 0.39-0.73) during follow-up as overweight individuals. While the amputation risk continued to decrease for higher BMI, amputation-free survival showed a slight upturn at BMI >40 kg/m(2). The association between obesity and amputation risk in our data shows a pattern consistent with "obesity paradox" observed in many health conditions. More research is needed to better understand pathophysiological mechanisms that may explain the paradoxical association between obesity and lower-extremity amputation (LEA) risk.

    Knowledge about cardiovascular (CV) disease in women with diabetes mellitus (DM) has changed substantially over the past 20 years. Coronary artery disease, strokes, and peripheral vascular disease affect women with DM at higher rates than the general population of women. Lifestyle therapies, such as dietary changes, physical activity, and smoking cessation, offer substantial benefits to women with DM. Of the pharmacotherapies, statins offer the most significant benefits, but may not be well tolerated in some women. Aspirin may also benefit high-risk women. Other pharmacotherapies, such as fibrates, ezetimibe, niacin, fish oil, and hormone replacement therapy, remain unproven and, in some cases, potentially dangerous to women with DM. To reduce CV events, risks to women with DM must be better publicized and additional research must be done. Finally, advancements in health care delivery must target high-risk women with DM to lower risk factors and effectively improve cardiovascular health. PMID:26391392

    The aim of the present study was to investigate the association between the altered ideal cardiovascular health status (ΔCHS) and the risk of developing diabetes mellitus in the Kailuan population of China.We included 50,656 Chinese adults aged 18 years or older (11,704 men and 38,952 women) without baseline diabetes mellitus in this study. Information about 7 individual components of the cardiovascular health metrics during 2006 to 2008 was collected. A ΔCHS score was defined as the changes of ideal cardiovascular health status (CHS) from the year 2006 to 2008. New-onset diabetes was identified based on the history of diabetes, currently treated with insulin or oral hypoglycemic agents, or having a fasting blood glucose concentration ≥7.0 mmol/L during the 2010 to 2011 and 2012 to 2013 surveys. After a mean follow-up period of 3.80 years, a total of 3071 (6.06%) participants developed diabetes mellitus. Cox proportional hazards regression was used to calculate the hazard ratios and 95% confidence intervals for the CHS change and new-onset diabetes.A strong inverse association between the positive CHS changes and lower risks of developing diabetes mellitus was observed. After adjusting for age, sex, alcohol consumption, and other potential confounders, the hazard ratios for new-onset diabetes were 0.73, 0.59, 0.49, and 0.42 (95% confidence interval: 0.37-0.82; P trend <0.001) for those who met ΔCHS = -1, 0, 1, and ≥2, respectively, compared with the participants with ΔCHS ≤-2.The study concluded that the improved CHS was associated with the reduced risk of developing diabetes mellitus in this investigated Chinese population.

    Type 2 diabetes (T2D) is a common and serious disorder and is a significant risk factor for the development of cardiovascular disease, neuropathy, nephropathy, retinopathy, periodontal disease, and foot ulcers and amputations. The burden of disease associated with T2D has led to an emphasis on early identification of the millions of individuals at high risk so that management and intervention strategies can be effectively implemented before disease progression begins. With increasing knowledge about the genetic basis of T2D, several genomic-based strategies have been tested for their ability to improve risk assessment, management and prevention. Genetic risk scores have been developed with the intent to more accurately identify those at risk for T2D and to potentially improve motivation and adherence to lifestyle modification programs. In addition, evidence is building that oral antihyperglycemic medications are subject to pharmacogenomic variation in a substantial number of patients, suggesting genomics may soon play a role in determining the most effective therapies. T2D is a complex disease that affects individuals differently, and risk prediction and treatment may be challenging for health care providers. Genomic approaches hold promise for their potential to improve risk prediction and tailor management for individual patients and to contribute to better health outcomes for those with T2D.

    A strong link between obesity, insulin resistance, and metabolic syndrome has been reported with development of a new paradigm to type 2 diabetes mellitus (T2DM), with some evidence suggesting that beta-cell dysfunction is present before the onset of impaired glucose tolerance. Differentiating type 1 diabetes mellitus (T1DM) from T2DM is actually not very easy and there exists a number of overlapping characteristics. The autoantibody frequencies of seven antigens in T1DM patients may turn out to be actually having T2DM patients (pre-T2DM). T2DM patients generally have increased C-peptide levels (may be normal at time of diagnosis), usually no auto-antibodies, strong family history of diabetes, obese and show signs of insulin resistance (hypertension, acanthosis, PCOS). The American Academy of Paediatrics recommends lifestyle modifications ± metformin when blood glucose is 126-200 mg/dL and hemoglobin A1c (HbA1c) <8.5. Insulin is recommended when blood glucose is >200 mg/dL and HbA1c >8.5, with or without ketosis. Metformin is not recommended if the patient is ketotic, because this increases the risk of lactic acidosis. Metformin is currently the only oral hypoglycemic that has been approved for use in children. Knowing these subtle differences in mechanism, and knowing how to test patients for which mechanism (s) are causing their diabetes mellitus, may help us eventually tailor treatment programs on an individual basis.

    Objective Depression is increasingly recognized as a risk factor for type 2 diabetes, and is also commonly comorbid with anxiety. However, few studies have examined whether anxiety is predictive of diabetes risk. The objectives of this study are to examine the prospective relationship between anxiety disorders (generalized anxiety disorder, panic disorder, social phobia, and agoraphobia) and risk of type 2 diabetes over an 11-year period, and to investigate the association between anxiety and risk of diabetes-related complications among those with prevalent type 2 diabetes. Methods Data come from the 1993/6 and 2004/5 waves of the Baltimore Epidemiologic Catchment Area Study (N=1920), a population-based prospective cohort. Anxiety disorders were assessed using the Diagnostic Interview Schedule. The prospective association between anxiety and incident type 2 diabetes was evaluated using a series of nested multivariable logistic regression models. Results At baseline, 315 participants (21.8%) had an anxiety disorder. The relationship between anxiety and risk of developing type 2 diabetes was not statistically significant after controlling for demographic characteristics (Odds Ratio (OR): 1.28, 95% Confidence Interval (CI): 0.75, 2.18). There was no relationship between anxiety and diabetes risk after controlling for health behaviors and depression status (OR: 1.00, 95% CI: 0.53, 1.89). There was no significant relationship between anxiety and development of diabetes-related complications among those with prevalent type 2 diabetes (OR: 2.02, 95% CI: 0.61, 6.74). Conclusion Anxiety disorders are not associated with increased risk of type 2 diabetes or risk of diabetes complications among those who have diabetes in the present study. PMID:23148808

    Diabetic encephalopathy is a diabetic complication related to the metabolic alterations featuring diabetes. Diabetes is characterized by increased lipid peroxidation, altered glutathione redox status, exacerbated levels of ROS, and mitochondrial dysfunction. Although the pathophysiology of diabetic encephalopathy remains to be clarified, oxidative stress and mitochondrial dysfunction play a crucial role in the pathogenesis of chronic diabetic complications. Taking this into consideration, the aim of this work was to evaluate the effects of 90-day avocado oil intake in brain mitochondrial function and oxidative status in streptozotocin-induced diabetic rats (STZ rats). Avocado oil improves brain mitochondrial function in diabetic rats preventing impairment of mitochondrial respiration and mitochondrial membrane potential (ΔΨ m ), besides increasing complex III activity. Avocado oil also decreased ROS levels and lipid peroxidation and improved the GSH/GSSG ratio as well. These results demonstrate that avocado oil supplementation prevents brain mitochondrial dysfunction induced by diabetes in association with decreased oxidative stress. PMID:26180820

    Diabetic encephalopathy is a diabetic complication related to the metabolic alterations featuring diabetes. Diabetes is characterized by increased lipid peroxidation, altered glutathione redox status, exacerbated levels of ROS, and mitochondrial dysfunction. Although the pathophysiology of diabetic encephalopathy remains to be clarified, oxidative stress and mitochondrial dysfunction play a crucial role in the pathogenesis of chronic diabetic complications. Taking this into consideration, the aim of this work was to evaluate the effects of 90-day avocado oil intake in brain mitochondrial function and oxidative status in streptozotocin-induced diabetic rats (STZ rats). Avocado oil improves brain mitochondrial function in diabetic rats preventing impairment of mitochondrial respiration and mitochondrial membrane potential (ΔΨ m ), besides increasing complex III activity. Avocado oil also decreased ROS levels and lipid peroxidation and improved the GSH/GSSG ratio as well. These results demonstrate that avocado oil supplementation prevents brain mitochondrial dysfunction induced by diabetes in association with decreased oxidative stress.

    Aims/hypothesis Serum potassium has been found to be a significant predictor of diabetes risk, but the effect of dietary potassium on diabetes risk is not clear. We sought to determine if dietary potassium is associated with risk of incident type 2 diabetes in young adults. Methods We used data from the Coronary Artery Risk Development in Young Adults (CARDIA) Study. Potassium intake was measured by (1) an average of three 24 h urinary potassium collections at the 5-year study visit, and (2) the CARDIA dietary assessment instrument at baseline. Incident type 2 diabetes cases were ascertained on the basis of use of diabetes medication and laboratory measurements. Analyses were adjusted for relevant confounders including intake of fruit and vegetables and other dietary factors. Results Of 1,066 participants with urinary potassium measurements, 99 (9.3%) developed diabetes over 15 years of follow-up. In multivariate models, adults in the lowest urinary potassium quintile were more than twice as likely to develop diabetes as their counterparts in the highest quintile (HR 2.45; 95% CI 1.08, 5.59). Of 4,754 participants with dietary history measurements, 373 (7.8%) developed diabetes over 20 years of follow-up. In multivariate models, African-Americans had a significantly increased risk of diabetes with lower potassium intake, which was not found in whites. Conclusions/interpretation Low dietary potassium is associated with increased risk of incident diabetes in African-Americans. Randomised clinical trials are needed to determine if potassium supplementation, from either dietary or pharmacological sources, could reduce the risk of diabetes, particularly in higher-risk populations.

    Type 2 diabetes is a major health burden in the United States, and population trends suggest this burden will increase. High interest in, and increased availability of, testing for genetic risk of type 2 diabetes presents a new opportunity for reducing type 2 diabetes risk for many patients; however, to date, there is little evidence that genetic testing positively affects type 2 diabetes prevention. Genetic information may not fit patients' illness representations, which may reduce the chances of risk-reducing behavior changes. The present study aimed to examine illness representations in a clinical sample who are at risk for type 2 diabetes and interested in genetic testing. The authors used the Common Sense Model to analyze survey responses of 409 patients with type 2 diabetes risk factors. Patients were interested in genetic testing for type 2 diabetes risk and believed in its importance. Most patients believed that genetic factors are important to developing type 2 diabetes (67%), that diet and exercise are effective in preventing type 2 diabetes (95%), and that lifestyle changes are more effective than drugs (86%). Belief in genetic causality was not related to poorer self-reported health behaviors. These results suggest that patients' interest in genetic testing for type 2 diabetes might produce a teachable moment that clinicians can use to counsel behavior change. PMID:25844569

    Current Clinical Management Guidelines of Diabetic Peripheral Neuropathy (DPN) are based on adequate glucose control and symptomatic pain relief. However, meticulous glycemic control could delay the onset or slow the progression of diabetic neuropathy in patients with DM type 2, but it does not completely prevent the progression of the disease. Complications of DPN as it continues its natural course, produce increasing pain and discomfort, loss of sensation, ulcers, infections, amputations and even death. In addition to the increased suffering, disability and loss of productivity, there is a very significant economic impact related to the treatment of DPN and its complications. In USA alone, it has been estimated that there are more than 5,000,000 patients suffering from DPN and the total annual cost of treating the disease and its complications is over $10,000 million dollars. In order to be able to reduce complications of DPN, it is crucial to improve or correct the metabolic conditions that lead to the pathology present in this condition. Pathophysiologic mechanisms implicated in diabetic neuropathy include: increased polyol pathway with accumulation of sorbitol and reduced Na+/K+-ATPase activity, microvascular damage and hypoxia due to nitric oxide deficit and increased oxygen free radical activity. Moreover, there is a decrease in glutathione and increase in homocysteine. Clinical trials in the last two decades have demonstrated that the use of specific nutrients can correct some of these metabolic derangements, improving symptom control and providing further benefits such as improved sensorium, blood flow and nerve regeneration. We will discuss the evidence on lipoic acid, acetyi-L-carnitine, benfotiamine and the combination of active B vitamins L-methylfolate, methylcobalamin and piridoxal-6-phosphate. In addition, we discuss the role of metforrnin, an important drug in the management of diabetes, and the presence of specific polymorphic genes, in the risk

    Food insecurity--defined as not having adequate quantity and quality of food at all times for all household members to have an active, healthy life--is a risk factor for poor diabetes control, yet few diabetes interventions address this important factor. Food pantries, which receive food from food banks and distribute it to clients in need, may be ideal sites for diabetes self-management support because they can provide free diabetes-appropriate food to people in low-income communities. Between February 2012 and March 2014, we enrolled 687 food pantry clients with diabetes in three states in a six-month pilot intervention that provided them with diabetes-appropriate food, blood sugar monitoring, primary care referral, and self-management support. Improvements were seen in pre-post analyses of glycemic control (hemoglobin A1c decreased from 8.11 percent to 7.96 percent), fruit and vegetable intake (which increased from 2.8 to 3.1 servings per day), self-efficacy, and medication adherence. Among participants with elevated HbA1c (at least 7.5 percent) at baseline, HbA1c improved from 9.52 percent to 9.04 percent. Although food pantries are nontraditional settings for diabetes support, this pilot study suggests a promising health promotion model for vulnerable populations. Policies supporting such interventions may be particularly effective because of food pantries' food access and distribution capacity.

    Many studies have investigated the association between Glutathione S-Transferase M1 (GSTM1) null genotype and risk of diabetes mellitus, but the impact of GSTM1 null genotype on diabetes mellitus is unclear owing to the obvious inconsistence among those studies. This study aimed to quantify the strength of association between GSTM1 null genotype and risk of diabetes mellitus. We searched the PubMed, Embase and Wangfang databases for studies relating the association between GSTM1 null genotype and risk of diabetes mellitus. We estimated summary odds ratio (OR) with their 95 % confidence interval (95 % CI) to assess the association. Subgroup analyses were performed by type of diabetes and ethnicity. 10 case-control studies with 7, 054 subjects were included into this meta-analysis. Meta-analysis of total 10 studies showed GSTM1 null genotype was associated increased risk of diabetes mellitus (OR = 1.59, 95 % CI 1.14-2.22, P = 0.007). Subgroup analyses by type of diabetes mellitus suggested GSTM1 null genotype was associated increased risk of type 2 diabetes (OR = 1.90, 95 % CI 1.37-2.64, P < 0.001), but was not associated with risk of type 1 diabetes (OR = 0.84, 95 % CI 0.66-1.07, P = 0.153). Subgroup analysis by ethnicity further identified the obvious association between GSTM1 null genotype and increased risk of type 2 diabetes. The cumulative meta-analyses showed a trend of obvious association between GSTM1 null genotype and risk of type 2 diabetes as information accumulated. No evidence of publication bias was observed. Thus, evidence from current meta-analysis suggests an association between GSTM1 null genotype and risk of type 2 diabetes.

    Diabetic peripheral neuropathy is a common complication of diabetes mellitus, and a significant proportion of individuals suffer debilitating pain that significantly affects their quality of life. Unfortunately, symptomatic treatment options have limited efficacy, and often carry significant risk of systemic adverse effects. Activation of the adenosine A1 receptor (A1R) by the analgesic small molecule adenosine has been shown to have antinociceptive benefits in models of inflammatory and neuropathic pain. The current study used a mouse model of painful diabetic neuropathy to determine the effect of diabetes on endogenous adenosine production, and if central or peripheral delivery of adenosine receptor agonists could alleviate signs of mechanical allodynia in diabetic mice. Diabetes was induced using streptozocin in male A/J mice. Mechanical withdrawal thresholds were measured weekly to characterize neuropathy phenotype. Hydrolysis of AMP into adenosine by ectonucleotidases was determined in the dorsal root ganglia (DRG) and spinal cord at 8 weeks post-induction of diabetes. AMP, adenosine and the specific A1R agonist, N(6)-cyclopentyladenosine (CPA), were administered both centrally (intrathecal) and peripherally (intraplantar) to determine the effect of activation of adenosine receptors on mechanical allodynia in diabetic mice. Eight weeks post-induction, diabetic mice displayed significantly decreased hydrolysis of extracellular AMP in the DRG; at this same time, diabetic mice displayed significantly decreased mechanical withdrawal thresholds compared to nondiabetic controls. Central delivery AMP, adenosine and CPA significantly improved mechanical withdrawal thresholds in diabetic mice. Surprisingly, peripheral delivery of CPA also improved mechanical allodynia in diabetic mice. This study provides new evidence that diabetes significantly affects endogenous AMP hydrolysis, suggesting that altered adenosine production could contribute to the development of

    Purpose: This study examined the associations between participant and site characteristics and retention in a multisite cardiovascular disease risk reduction project. Design and Methods: Data were derived from the Special Diabetes Program for Indians Healthy Heart Demonstration Project, an intervention to reduce cardiovascular risk among American Indians and Alaska Natives with diabetes. In 2006, a total of 1,072 participants from 30 participating sites completed baseline questionnaires measuring demographics and sociobehavioral factors. They also underwent a medical examination at baseline and were reassessed annually after baseline. A Provider Annual Questionnaire was administered to staff members of each grantee site at the end of each year to assess site characteristics. Generalized estimating equation models were used to evaluate the relationships between participant and site characteristics and retention 1 year after baseline. Results: Among enrolled participants, 792 (74%) completed their first annual assessment. Participants who completed the first annual assessment tended to be older and had, at baseline, higher body mass index and higher level of physical activity. Site characteristics associated with retention included average age of staff, proportion of female staff members, and percentage of staff members having completed graduate or professional school. Implications: Understanding successful retention must reach beyond individual characteristics of participants to include features of the settings that house the interventions.

    Rates of diabetes and its associated comorbidities have been increasing in the United States, with diabetic foot ulcer treatment representing a large cost to the patient and healthcare system. These ulcers often result in multiple hospital admissions. This study examined readmissions following inpatient care for a diabetic foot ulcer and identified modifiable factors associated with all-cause 30-day readmissions to the inpatient or emergency department (ED) setting. We hypothesized that patients undergoing aggressive treatment would have lower 30-day readmission rates. We identified patient discharge records containing International Classification of Disease ninth revision codes for both diabetes mellitus and distal foot ulcer in the State Inpatient and Emergency Department databases from the Agency for Healthcare Research and Quality, Healthcare Cost and Utilization Project in Florida and New York, 2011-2012. All-cause 30-day return to care visits (ED or inpatient) were analyzed. Patient demographics and treatment characteristics were evaluated using univariate and multivariable regression models. The cohort included 25,911 discharges, having a mean age of 63 and an average of 3.8 comorbidities. The overall rate of return to care was 30%, and 21% of subjects underwent a toe or midfoot amputation during their index stay. The most common diagnosis codes upon readmission were diabetes mellitus (19%) and infection (13%). Patients with a toe or midfoot amputation procedure were less likely to be readmitted within 30 days (odds ratio: 0.78; 95% confidence interval: 0.73, 0.84). Presence of comorbidities, black and Hispanic ethnicities, and Medicare and Medicaid payer status were also associated with higher odds of readmission following initial hospitalization (p < 0.05). The study suggests that there are many factors that affect readmission rates for diabetic foot ulcer patients. Understanding patients at high-risk for readmission can improve counseling and

    OBJECTIVE To determine the independent association between diabetes and surgical site infection (SSI) across multiple surgical procedures. DESIGN Systematic review and meta-analysis. METHODS Studies indexed in PubMed published between December 1985 and through July 2015 were identified through the search terms "risk factors" or "glucose" and "surgical site infection." A total of 3,631 abstracts were identified through the initial search terms. Full texts were reviewed for 522 articles. Of these, 94 articles met the criteria for inclusion. Standardized data collection forms were used to extract study-specific estimates for diabetes, blood glucose levels, and body mass index (BMI). A random-effects meta-analysis was used to generate pooled estimates, and meta-regression was used to evaluate specific hypothesized sources of heterogeneity. RESULTS The primary outcome was SSI, as defined by the Centers for Disease Control and Prevention surveillance criteria. The overall effect size for the association between diabetes and SSI was odds ratio (OR)=1.53 (95% predictive interval [PI], 1.11-2.12; I2, 57.2%). SSI class, study design, or patient BMI did not significantly impact study results in a meta-regression model. The association was higher for cardiac surgery 2.03 (95% PI, 1.13-4.05) compared with surgeries of other types (P=.001). CONCLUSIONS These results support the consideration of diabetes as an independent risk factor for SSIs for multiple surgical procedure types. Continued efforts are needed to improve surgical outcomes for diabetic patients. Infect. Control Hosp. Epidemiol. 2015;37(1):88-99.

    Diabetes mellitus, especially type 2, is a metabolic disease involving the coexistence of several cardiovascular risk factors. Affected patients are therefore at high cardiovascular risk (2-3 times higher than that of men in the general population and 2-6 times higher than that of women). Cardiovascular disease is the main cause of death in the diabetic population, followed by cancer. Cardiovascular risk cannot be compared between diabetic patients and persons who have already shown one or more manifestations of cardiovascular disease (such as myocardial infarction). Single risk factors should be evaluated in combination with other risk factors and a person's cardiovascular risk should be individually assessed. Cardiovascular risk assessment in patients with diabetes through current calculations methods is complex because their ability to predict risk in individuals is very low. Studies such as that by Steno have demonstrated the validity of a comprehensive strategy to control all the risk factors present in persons with type 2 diabetes mellitus, which can reduce the development of micro- and macrovascular complications and mortality by almost 50%. The present article reviews each of the classical cardiovascular risk factors (hypertension, dyslipidemia, smoking, obesity, sedentariness) in relation to diabetes, as well as their recommended targets and the benefits of their control. In view of the above, a comprehensive approach is recommended to control the multiple risk factors that can coexist in persons with type 2 diabetes mellitus.

    Diabetes is a potent risk factor for heart failure with preserved ejection fraction (HFpEF). Autophagy can be activated under pathological conditions, including diabetic cardiomyopathy. The therapeutic effects of chloroquine (CQ), an autophagy inhibitor, on left ventricle function in streptozotocin (STZ)-induced diabetic mice were investigated. The cardiac function, light chain 3 (LC3)-II/LC3-I ratio, p62, beclin 1, reactive oxygen species, apoptosis, and fibrosis were measured 14 days after CQ (ip 60 mg/kg/d) administration. In STZ-induced mice, cardiac diastolic function was decreased significantly with normal ejection fraction. CQ significantly ameliorated cardiac diastolic function in diabetic mice with HFpEF. In addition, CQ decreased the autophagolysosomes, cardiomyocyte apoptosis, and cardiac fibrosis but increased LC3-II and p62 expressions. These results suggested that CQ improved the cardiac diastolic function by inhibiting autophagy in STZ-induced HFpEF mice. Autophagic inhibitor CQ might be a potential therapeutic agent for HFpEF.

    2014-01-01

    Background Previous work has found that people with diabetes do not wear their therapeutic footwear as directed, but the thinking behind this behaviour is unclear. Adherence to therapeutic footwear advice must improve in order to reduce foot ulceration and amputation risk in people with diabetes and neuropathy. Therefore this study aimed to explore the psychological influences and personal experiences behind the daily footwear selection of individuals with diabetes and neuropathy. Methods An interpretative phenomenological analysis (IPA) approach was used to explore the understanding and experience of therapeutic footwear use in people living at risk of diabetic neuropathic foot ulceration. This study benefited from the purposive selection of a small sample of four people and used in-depth semi structured interviews because it facilitated the deep and detailed examination of personal thoughts and feelings behind footwear selection. Findings Four overlapping themes that interact to regulate footwear choice emerged from the analyses: a) Self-perception dilemma; resolving the balance of risk experienced by people with diabetes and neuropathy day to day, between choosing to wear footwear to look and feel normal and choosing footwear to protect their feet from foot ulceration; b) Reflective adaption; The modification and individualisation of a set of values about footwear usage created in the minds of people with diabetes and neuropathy; c) Adherence response; The realignment of footwear choice with personal values, to reinforce the decision not to change behaviour or bring about increased footwear adherence, with or without appearance management; d) Reality appraisal; A here and now appraisal of the personal benefit of footwear choice on emotional and physical wellbeing, with additional consideration to the preservation of therapeutic footwear. Conclusion For some people living at risk of diabetic neuropathic foot ulceration, the decision whether or not to wear

    This was a cross-sectional study designed to assess the validity of the Finnish Diabetes Risk Score for detecting undiagnosed type 2 diabetes among general medical outpatients in Botswana. Participants aged ≥20 years without previously diagnosed diabetes were screened by (1) an 8-item Finnish diabetes risk assessment questionnaire and (2) Haemoglobin A1c test. Data from 291 participants were analyzed (74.2% were females). The mean age of the participants was 50.1 (SD = ±11) years, and the prevalence of undiagnosed diabetes was 42 (14.4%) with no significant differences between the gender (20% versus 12.5%, P = 0.26). The area under curve for detecting undiagnosed diabetes was 0.63 (95% CI 0.55–0.72) for the total population, 0.65 (95% CI: 0.56–0.75) for women, and 0.67 (95% CI: 0.52–0.83) for men. The optimal cut-off point for detecting undiagnosed diabetes was 17 (sensitivity = 48% and specificity = 73%) for the total population, 17 (sensitivity = 56% and specificity = 66%) for females, and 13 (sensitivity = 53% and specificity = 77%) for males. The positive predictive value and negative predictive value were 20% and 89.5%, respectively. The findings indicate that the Finnish questionnaire was only modestly effective in predicting undiagnosed diabetes among outpatients in Botswana. PMID:27738638

Data Sources/Study Setting Data regarding the impact of the Diabetes HDC program came from a serial cross-sectional follow-up study (1998, 2000, 2002) of the program in 17 Midwestern HCs. Data inputs for the simulation model of diabetes came from the latest clinical trials and epidemiological studies. Study Design We conducted a societal cost-effectiveness analysis, incorporating data from QI program evaluation into a Monte Carlo simulation model of diabetes. Data Collection/Extraction Methods Data on diabetes care processes and risk factor levels were extracted from medical charts of randomly selected patients. Principal Findings From 1998 to 2002, multiple processes of care (e.g., glycosylated hemoglobin testing [HbA1C] [71→92 percent] and ACE inhibitor prescribing [33→55 percent]) and risk factor levels (e.g., 1998 mean HbA1C 8.53 percent, mean difference 0.45 percent [95 percent confidence intervals −0.72, −0.17]) improved significantly. With these improvements, the HDC was estimated to reduce the lifetime incidence of blindness (17→15 percent), end-stage renal disease (18→15 percent), and coronary artery disease (28→24 percent). The average improvement in quality-adjusted life year (QALY) was 0.35 and the incremental cost-effectiveness ratio was $33,386/QALY. Conclusions During the first 4 years of the HDC, multiple improvements in diabetes care were observed. If these improvements are maintained or enhanced over the lifetime of patients, the HDC program will be cost-effective for society based on traditionally accepted thresholds. PMID:17995559

    In parallel with the type 2 diabetes pandemic, diabetic kidney disease has become the leading cause of end-stage renal disease worldwide, and is associated with high cardiovascular morbidity and mortality. As established in landmark randomised trials and recommended in clinical guidelines, prevention and treatment of diabetic kidney disease focuses on control of the two main renal risk factors, hyperglycaemia and systemic hypertension. Treatment of systemic hypertension with angiotensin-converting enzyme inhibitors or angiotensin-receptor blockers is advocated because these drugs seem to exert specific renoprotective effects beyond blood pressure lowering. Emerging evidence shows that obesity, glomerular hyperfiltration, albuminuria, and dyslipidaemia might also adversely affect the kidney in diabetes. Control of these risk factors could have additional benefits on renal outcome in patients with type 2 diabetes. However, despite multifactorial treatment approaches, residual risk for the development and progression of diabetic kidney disease in patients with type 2 diabetes remains, and novel strategies or therapies to treat the disease are urgently needed. Several drugs used in the treatment of type 2 diabetes are associated with pleiotropic effects that could favourably or unfavourably change patients' renal risk profile. We review the risk factors and treatment of diabetic kidney disease, and describe the pleiotropic effects of widely used drugs in type 2 diabetes management on renal outcomes, with special emphasis on antihyperglycaemic drugs.

    OBJECTIVE-Impaired endothelial function of resistance and conduit arteries can be detected in patients with type 1 diabetes. We studied whether a persistent improvement of endothelial function can be achieved by regular physical training. RESEARCH DESIGN AND METHODS-The study included 26 patients with type 1 diabetes of 20 +/- 10 years' duration and no overt angiopathy; 18 patients (42 +/- 10 years old) participated in a bicycle exercise training program, and 8 patients with type 1 diabetes (33 +/- 11 years old) served as control subjects. Vascular function of conduit arteries was assessed by flow-mediated and endothelium-independent dilation of the brachial artery and of resistance vessels by the response of ocular fundus pulsation amplitudes to intravenous N(G)-monomethyl-L-arginine (L-NMMA) at baseline, after 2 and 4 months of training, and 8 months after cessation of regular exercise. RESULTS-Training increased peak oxygen uptake (VO(2max)) by 13% after 2 months and by 27% after 4 months (P = 0.04). Flow-mediated dilation (FMD) of the brachial artery increased from 6.5 +/- 1.1 to 9.8 +/- 1.1% (P = 0.04) by training. L-NMMA administration decreased fundus pulsation amplitude (FPA) by 9.1 +/- 0.9% before training and by 13.4 +/- 1.5% after 4 months of training (P = 0.02). VO(2max), FMD, and FPA were unchanged in the control group. Vascular effects from training were abrogated 8 months after cessation of exercise. CONCLUSIONS-Our study demonstrates that aerobic exercise training can improve endothelial function in different vascular beds in patients with long-standing type 1 diabetes, who are at considerable risk for diabetic angiopathy. However, the beneficial effect on vascular function is not maintained in the absence of exercise.

    Aim We tested the hypothesis that short-term oral sodium nitrite supplementation would improve vascular dysfunction in obese, diabetic mice. Methods and results Vascular function was determined in control mice and in db/db mice receiving drinking water with or without sodium nitrite (50 mg/L) for 5 weeks. Nitrite supplementation increased plasma nitrite concentrations in db/db mice (0.19±0.02 μM vs 0.80±0.26μM; p < 0.05). Db/db mice had lower endothelium-dependent dilation (EDD) in response to increasing doses of acetylcholine versus heterozygous control mice (71.2% ± 14.3% vs 93% ± 7.0%; p < 0.05), and sodium nitrite supplementation restored endothelium-dependent dilation to control levels (92.9% ± 2.3% vs 93% ± 7.0%; p < 0.05). The improvement in endothelial function was accompanied by a reduction in intrinsic stiffness, but not by alterations in plasma or vascular markers of inflammation. Conclusion These data suggest that sodium nitrite may be a novel therapy for treating diabetes-related vascular dysfunction; however, the mechanisms of improvement are unknown. PMID:25696116

    Background Use of risk calculators for specific diseases is increasing, with an underlying assumption that they promote risk reduction as users become better informed and motivated to take preventive action. Empirical data to support this are, however, sparse and contradictory. Aim To explore user reactions to a cardiovascular risk calculator for people with type 2 diabetes. Objectives were to identify cognitive and emotional reactions to the presentation of risk, with a view to understanding whether and how such a calculator could help motivate users to adopt healthier behaviours and/or improve adherence to medication. Design and setting Qualitative study combining data from focus groups and individual user experience. Adults with type 2 diabetes were recruited through website advertisements and posters displayed at local GP practices and diabetes groups. Method Participants used a risk calculator that provided individualised estimates of cardiovascular risk. Estimates were based on UK Prospective Diabetes Study (UKPDS) data, supplemented with data from trials and systematic reviews. Risk information was presented using natural frequencies, visual displays, and a range of formats. Data were recorded and transcribed, then analysed by a multidisciplinary group. Results Thirty-six participants contributed data. Users demonstrated a range of complex cognitive and emotional responses, which might explain the lack of change in health behaviours demonstrated in the literature. Conclusion Cardiovascular risk calculators for people with diabetes may best be used in conjunction with health professionals who can guide the user through the calculator and help them use the resulting risk information as a source of motivation and encouragement.

    Through its hazardous materials (hazmat) review initiative, Wisconsin Power and Light Co. (WP and L) repositioned itself for better plant operations while reducing the overall risks and costs associated with hazmats. The utility focused on two primary hazmat improvement objectives: (1) ensure plant hazmat operations are meeting regulatory requirements, optimizing the use, storage, and disposal of hazmats; (2) reduce the overall risk and investment associated with hazmat substances on the plant properties. ``Hazardous materials management is often overlooked as an integral component of the overall purchasing and materials management process``, emphasized Jill Doucette, WP and L Strategic Sourcing Initiative manager. ``Improved performance in this area can significantly reduce personnel and company risks, improve customer service and save dollars.``

    Six medical units realized that they were having issues with accurate timing of bedtime blood glucose measurement for their patients with diabetes. They decided to investigate the issues by using their current staff nurse committee structure. The clinical nurse specialists and nurse education specialists decided to address the issue by educating and engaging the staff in the define, measure, analyze, improve, control (DMAIC) framework process. They found that two issues needed to be improved, including timing of bedtime blood glucose measurement and snack administration and documentation. Several educational interventions were completed and resulted in improved timing of bedtime glucose measurement and bedtime snack documentation. The nurses understood the DMAIC process, and collaboration and cohesion among the medical units was enhanced. PMID:24369753

    Diabetes is a major health problem with many social and economic consequences in general population. The importance of education in the diabetic patient and his family, led to the development of diabetes clinical nurse specialist. The role of diabetes clinical nurse specialist is essential and crucial to the hospitals and the community, in order to form a relationship with the diabetic patient and his/her family. In this way health is promoted to the maximum extent possible. In conclusion educational programs help patients with diabetes to obtain information about their condition and improve their self-care skills. PMID:26973922

    Classical paper-and-pencil based risk assessment questionnaires are often accompanied by the online versions of the questionnaire to reach a wider population. This study focuses on the loss, especially in risk estimation performance, that can be inflicted by direct transformation from the paper to online versions of risk estimation calculators by ignoring the possibilities of more complex and accurate calculations that can be performed using the online calculators. We empirically compare the risk estimation performance between four major diabetes risk calculators and two, more advanced, predictive models. National Health and Nutrition Examination Survey (NHANES) data from 1999-2012 was used to evaluate the performance of detecting diabetes and pre-diabetes. American Diabetes Association risk test achieved the best predictive performance in category of classical paper-and-pencil based tests with an Area Under the ROC Curve (AUC) of 0.699 for undiagnosed diabetes (0.662 for pre-diabetes) and 47% (47% for pre-diabetes) persons selected for screening. Our results demonstrate a significant difference in performance with additional benefits for a lower number of persons selected for screening when statistical methods are used. The best AUC overall was obtained in diabetes risk prediction using logistic regression with AUC of 0.775 (0.734) and an average 34% (48%) persons selected for screening. However, generalized boosted regression models might be a better option from the economical point of view as the number of selected persons for screening of 30% (47%) lies significantly lower for diabetes risk assessment in comparison to logistic regression (p < 0.001), with a significantly higher AUC (p < 0.001) of 0.774 (0.740) for the pre-diabetes group. Our results demonstrate a serious lack of predictive performance in four major online diabetes risk calculators.

    OBJECTIVE Type 2 diabetes has been linked with increased risk of dementia and cognitive impairment among older adults and with premature mortality in young and middle-aged adults. No studies have evaluated the association between diabetes and dementia among Mexican Americans, a population with a high burden of diabetes. We evaluated the association of diabetes with incidence of dementia and cognitive impairment without dementia (CIND) among older Mexican Americans while accounting for competing risk from death. RESEARCH DESIGN AND METHODS This study included 1,617 participants 60–98 years of age from the Sacramento Area Latino Study on Aging followed up to 10 years from 1998. We evaluated the association between diabetes and dementia/CIND with competing risk regression models. RESULTS Participants free of dementia/CIND at baseline (n = 1,617) were followed annually up to 10 years. There were 677 (41.9%) participants with diabetes, 159 (9.8%) incident dementia/CIND cases, and 361 (22.3%) deaths. Treated and untreated diabetes (hazard ratio 2.12 [95% CI 1.65–2.73] and 2.15 [1.58–2.95]) and dementia/CIND (2.48 [1.75–3.51]) were associated with an increased risk of death. In models adjusted for competing risk of death, those with treated and untreated diabetes had an increased risk of dementia/CIND (2.05 [1.41–2.97] and 1.55 [0.93–2.58]) compared with those without diabetes. CONCLUSIONS These findings provide evidence that the association between type 2 diabetes and dementia/CIND among Mexican Americans remains strong after accounting for competing risk of mortality. Treatments that modify risk of death among those with diabetes may change future dementia risk. PMID:23514732

    Previous studies suggested that neurotrophins play a role in the diabetic retinopathy (DR). We therefore evaluated the role of plasma brain derived neurotrophic factor (BDNF) levels in Chinese type 2 diabetic patients with and without diabetic retinopathy (DR). Plasma levels of BDNF were determined in type 2 diabetic patients (N=344). At baseline, the demographical and clinical data were taken. Multivariate analyses were performed using logistic regression models. Receiver operating characteristic curves (ROC) was used to test the overall predict accuracy of BDNF and other markers. Diabetic patients with DR and vision-threatening diabetic retinopathy (VTDR) had significantly lower BDNF levels on admission (P<0.0001 both). BDNF improved the area under the receiver operating characteristic curve of the diabetes duration for DR from 0.76 (95% confidence interval [CI], 0.71-0.82) to 0.89 (95% CI, 0.82-0.95; P<0.01) and for VDTR from 0.84 (95% CI, 0.78-0.92) to 0.95 (95% CI, 0.90-0.98; P<0.01). Multivariate logistic regression analysis adjusted for common risk factors showed that plasma BDNF levels≤12.4 ng/mL(1(rd) quartiles) was an independent marker of DR (OR=3.92; 95%CI: 2.31-6.56) and VTDR (OR=4.88; 95%CI: 2.21-9.30). The present study demonstrated that decreased plasma levels of BDNF were independent markers for DR and VDTR in Chinese type 2 diabetic patients, suggesting a possible role of BDNF in the pathogenesis of DR complications.

  7. The imperative to prevent diabetes complications: a broadening spectrum and an increasing burden despite improved outcomes.

    Diabetes mellitus and its complications are common; the complications are, of themselves, a major reason to manage diabetes. Recent data from Australia and similar developed health care systems overseas indicate that morbidity and mortality outcomes relating to diabetes complications are improving. However, these benefits are offset by increasing numbers of people diagnosed with diabetes, resulting in an increased disease burden with significant health care implications. Thus the imperative to prevent diabetes and diabetes complications has never been greater. Furthermore, the recognised spectrum of diabetes complications is broadening, especially complications relating to lipid levels, insulin resistance and the metabolic syndrome. Clinicians now need to be aware of both traditional complications (eg, nephropathy and cardiovascular disease) and non-traditional complications (eg, polycystic ovary syndrome, non-alcoholic fatty liver disease, some cancers and eating disorders). Complications outcomes could be further improved by decreasing the evidence-treatment gap - for example, by increasing personalisation of care in managing diabetes complications.

    We sought to identify risk factors for type 2 diabetes (T2D) in Jammu and Kashmir populations, India. A total of 424 diabetic and 226 non-diabetic subjects from Jammu, and 161 diabetic and 100 non-diabetic subjects from Kashmir were screened for various parameters including fasting blood glucose level, 2 hour glucose level, urea, creatinine, triglycerides, total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), very low-density lipoprotein (VLDL-C), uric acid, systolic and diastolic blood pressure level. We found that subjects aged 40-49 years had the highest rate of diabetes, with family income playing not much of a role. Kashmiri migrants or populations with rapid cultural, environmental, social or lifestyle change along with reduced physical activity, obesity and unhealthy lifestyle (smoking and alcohol consumption) were found to have higher rates of diabetes. High blood glucose, triglycerides and low HDL-C levels were found to be contributing to disease outcome. High blood pressure also contributed to a higher risk of developing T2D. Our study supports earlier reports confirming the contribution of comfortable life style, Western dietary habits and rapid life style change along with many other factors to the prevalence of diabetes. This may contribute to the epidemic proportion of diabetes in Jammu and Kashmir. Early diagnosis and routine screening for undiagnosed diabetes in obese subjects and subjects with parental diabetes history is expected to decrease the burden of chronic diabetic complications worldwide.

    This study was carried to ascertain whether stress responses are associated with abnormalities in glucose tolerance, insulin sensitivity and pancreatic beta cell function and risk of type 2 Diabetes Mellitus. Salivary cortisol, a marker of hypothalamic-pituitary-adrenal (HPA) axis and salivary α-amylase, a marker of sympathetic nervous system (SNS) were compared in 125 subjects of newly detected diabetes mellitus (NDDM) and normal glucose tolerance (NGT) subjects who were diagnosed on the basis of oral glucose tolerance test (OGTT). Assessment of stress in them was done through stress scales - presumptive stressful life events scale (PSLES), perceived stress scale (PSS) and sense of coherence (SOC) and correlated with these and other stress response markers. Significantly higher 10 pm salivary cortisol and post dexamethasone salivary cortisol were found in NDDM subjects as compared to NGT. 10 pm salivary cortisol correlated significantly with fasting plasma glucose (FPG), 2 h plasma glucose (2h PG) and glycated hemoglobin (HbA1c) while post dex salivary cortisol correlated with 2h PG, HbA1c and salivary α-amylase with 2h PG. Stepwise logistic regression analysis showed that body mass index (OR: 1.840), SOC (OR: 0.688) and 10 pm salivary cortisol (OR: 1.427) were the strongest predictors of NDDM. The results of the present study indicate that NDDM subjects display significantly higher chronic stress and stress responses when compared to subjects with NGT. Chronic stress and endocrine stress responses are significantly associated with glucose intolerance, insulin resistance and diabetes mellitus. PMID:26303379

    Introduction Cardiovascular events (CE) due to atherosclerosis are preventable. Identification of high-risk patients helps to focus resources on those most likely to benefit from expensive therapy. Atherosclerosis is not considered for patient risk categorization, even though a fraction of CE are predicted by Framingham risk factors. Our objective was to assess the incremental value of combining total plaque area (TPA) with the Framingham risk score (FramSc) using post-test probability (Ptp) in order to categorize risk in patients without CE and identify those at high risk and requiring intensive treatment. Material and methods A descriptive cross-sectional study was performed in the primary care setting in an Argentine population aged 22–90 years without CE. Both FramSc based on body mass index and Ptp-TPA were employed in 2035 patients for risk stratification and the resulting reclassification was compared. Total plaque area was measured with a high-resolution duplex ultrasound scanner. Results 57% male, 35% hypertensive, 27% hypercholesterolemia, 14% diabetes. 20.1% were low, 28.5% moderate, and 51.5% high risk. When patients were reclassified, 36% of them changed status; 24.1% migrated to a higher and 13.6% to a lower risk level (κ index = 0.360, SE κ = 0.16, p < 0.05, FramSc vs. Ptp-TPA). With this reclassification, 19.3% were low, 18.9% moderate and 61.8% high risk. Conclusions Quantification of Ptp-TPA leads to higher risk estimation than FramSc, suggesting that Ptp-TPA may be more sensitive than FramSc as a screening tool. If our observation is confirmed with a prospective study, this reclassification would improve the long-term benefits related to CE prevention. PMID:27279842

    Abstract This study aimed to examine whether poor glycemic control, measured by glycated hemoglobin A1C (HbA1c) and other cardiovascular risk factors, can predict diabetic peripheral neuropathy (DPN) in patients with type 2 diabetes mellitus (DM). Patients aged ≥30 years with type 2 DM, enrolled in the National Diabetes Care Management Program, and free of DPN (n = 37,375) in the period 2002 to 2004 were included and followed up until 2011. The related factors were analyzed using Cox proportional hazards regression models. For an average follow-up of 7.00 years, 8379 cases of DPN were identified, with a crude incidence rate of 32.04/1000 person-years. After multivariate adjustment, patients with HbA1c levels 7 to 8%, 8 to 9%, 9 to 10%, and ≥10% exhibited higher risk of DPN (adjusted HR: 1.11 [1.04–1.20], 1.30 [1.21–1.40], 1.32 [1.22–1.43], and 1.62 [1.51–1.74], respectively) compared with patients with HbA1c level 6 to 7%. There was a significant linear trend in DPN incidence with increasing HbA1c (P < 0.001) and significant HRs of DPN for patients with HbA1c level ≥7%, blood pressure ≥130/85 mm Hg, triglycerides (TG) ≥150 mg/dL, high density of lipoprotein-cholesterol (HDL-C) <40 mg/dL in males and <50 mg/dL in females, low density of lipoprotein-cholesterol (LDL-C) ≥100 mg/dL, and estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2. Patients with type 2 DM and HbA1c ≥7.0% exhibit increased risk of DPN, demonstrating a linear relationship. The incidence of DPN is also associated with poor glucose control and cardiovascular risk factors like hypertension, hyper-triglyceridemia, low HDL-C, high LDL-C, and decreased eGFR. PMID:26496307

    OBJECTIVE To investigate whether parental family history of diabetes influences cardiovascular outcomes in type 2 diabetes. RESEARCH DESIGN AND METHODS We studied 1,294 type 2 diabetic patients (mean age 64.1 years, 51.2% female) recruited to a community-based cohort study from 1993 to 1996 and followed until mid-2006. A data linkage system assessed all-cause and cardiac mortality, incident myocardial infarction, and stroke. Cox proportional hazards modeling was used to determine the influence of maternal or paternal family history on these outcomes. RESULTS A maternal family history of diabetes was reported by 20.4% of the cohort, 8.3% reported paternal family history, and 2.0% reported both parents affected. Maternal and paternal family history was associated with earlier age of diabetes onset, and maternal family history was associated with worse glycemic control. For all patients, maternal family history was significantly associated with reduced risk of all-cause mortality and cardiac mortality. When analyzed by sex, maternal family history had no effect on male patients, whereas female patients with diabetic mothers had significantly reduced hazard ratios for death from all causes (0.63 [95% CI 0.41–0.96]; P = 0.033), for death from cardiac causes (0.32 [0.14–0.72]; P = 0.006), and for first myocardial infarction (0.45 [0.26–0.76]; P = 0.003). Paternal family history status was not associated with these outcomes. CONCLUSIONS A maternal family history of diabetes confers relative protection against cardiovascular disease in female patients but not in male patients with type 2 diabetes. Paternal family history is associated with risks equivalent to those without a family history of diabetes. Some of the clinical heterogeneity of type 2 diabetes is related to maternal transmission effects with differential impact on male and female patients. PMID:20368412

    Background: As food insecurity has negative effects on health, the aim of this study was to determine tahe relationship between household food security and type 2 diabetes mellitus and its related risk factors. Methods: In this case-control study, 200 individuals with and 200 individuals without type 2 diabetes mellitus, aged over 40 years, were randomly selected from among participants of the Tehran Lipid and Glucose Study. The questionnaire on household food security proposed by the United States Department of Agriculture was completed for them by trained personnel. Logistic regression was used to determine the variable that had the most significant relationship with food security status. Results: The average of food security score was 2.38 ± 2.0 in non-diabetic and 2.25 ± 2.0 in diabetic individuals (P = 0.6). In both groups, the risk for food insecurity in women was more than in men. In the diabetic group, being single and having education levels below high school increased the risk of food insecurity. In the non-diabetic group, the risk of food insecurity in obese individuals was 3.3 times higher than normal individuals (odds ratio = 2.1, 95% confidence interval: 1.2–4.1). Conclusions: There were no significant differences in food security levels of diabetic and non-diabetic groups. However, some risk factors of type 2 diabetes including sex, marital status, educational level, and obesity were associated with food insecurity. PMID:26605019

    Background: The prevalence of Type-2 Diabetes is dramatically increasing in urban areas within Saudi Arabia. Hence, Type-2 Diabetes has now become the most common public health problem. Understanding the major risk factors for and barriers to control Type-2 Diabetes may lead to strategies to prevent, control, and reduce in the burden of disease cases. Objective: To describe risk factors for and barriers to control Type- 2 Diabetes in Saudi Arabia. Methods: The literature search was conducted on risk factors for and barriers to control Type- 2 Diabetes in Saudi Arabia using the databases PubMed, MEDLINE, and Google Scholar (2007-2015). The literature search yielded 80 articles, of which 70 articles were included in this review after excluding non-relevant articles. Results: The literature review revealed that obesity, physical inactivity, unhealthy diet, smoking, and aging are the major risk factors for Type-2 Diabetes in Saudi Arabia. Further, the review allocated a complex set of barriers including, lack of education, social support, and healthy environment. These barriers may hinder Saudis with Type-2 Diabetes from controlling their disease. Conclusion: The prevalence of Type-2 Diabetes is high among the Saudi population and represents a major public health problem. Effective research programs are needed to address the modifiable risk factors for and barriers to control Type-2 Diabetes among Saudi population. PMID:27157156

  17. The association of hypertension and diabetes: prevalence, cardiovascular risk and protection by blood pressure reduction.

    Diabetes and hypertension frequently coexist, and their combination provides additive increases in the risk of life-threatening cardiovascular events. Recent guidelines agree on the need for early, aggressive reduction of blood pressure, with a goal of <130/80 mmHg, in patients with diabetes. The mechanism that underpins the increased sensitivity of diabetic subjects to hypertension is not known, but may involve impaired autoregulation or attenuated nocturnal decrease of blood pressure. All classes of antihypertensive agents are effective in reducing blood pressure in diabetic subjects, and all show evidence of a concomitant reduction in cardiovascular risk. Although there is some evidence that agents that interrupt the renin-angiotensin system (RAS) provide greater protective effects, the data are not conclusive. However, most diabetic subjects will require combination therapy to reach goal blood pressure. Antihypertensive drugs can also significantly influence the probability that otherwise healthy individuals will develop metabolic syndrome or type 2 diabetes. While diuretics and betablockers have a prodiabetic effect, angiotensin-converting enzyme inhibitors and angiotensin II receptor blockers may prevent diabetes more effectively than the metabolically neutral calcium channel blockers. Given that diabetes is an important cardiovascular risk factor, there is the potential for reductions in risk due to reduced blood pressure to be offset by an increased risk due to the development of diabetes. Such concerns should be considered in the selection of antihypertensive therapy. PMID:15868115

    Objectives Although type 2 diabetes mellitus is a known risk factor for pancreatic cancer, the existence of shared genetic susceptibility is largely unknown. We evaluated whether any reported genetic risk variants of either disease found by genome-wide association studies reciprocally confer susceptibility. Methods Data that were generated in previous genome-wide association studies (GENEVA Type 2 Diabetes; PanScan) were obtained through the National Institutes of Health database of Genotypes and Phenotypes (dbGaP). Using the PanScan datasets, we tested for association of 38 variants within 37 genomic regions known to be susceptibility factors for type 2 diabetes. We further examined whether type 2 diabetes variants predispose to pancreatic cancer risk stratified by diabetes status. Correspondingly, we examined the association of fourteen pancreatic cancer susceptibility variants within eight genomic regions in the GENEVA Type 2 Diabetes dataset. Results Four plausible associations of diabetes variants and pancreatic cancer risk were detected at a significance threshold of p = 0.05, and one pancreatic cancer susceptibility variant was associated with diabetes risk at threshold of p = 0.05, but none remained significant after correction for multiple comparisons. Conclusion Currently identified GWAS susceptibility variants are unlikely to explain the potential shared genetic etiology between Type 2 diabetes and pancreatic cancer. PMID:25658847

    Background— The prevalence of pre–diabetes mellitus and its consequences in patients with heart failure and reduced ejection fraction are not known. We investigated these in the Prospective Comparison of ARNI With ACEI to Determine Impact on Global Mortality and Morbidity in Heart Failure (PARADIGM-HF) trial. Methods and Results— We examined clinical outcomes in 8399 patients with heart failure and reduced ejection fraction according to history of diabetes mellitus and glycemic status (baseline hemoglobin A1c [HbA1c]: <6.0% [<42 mmol/mol], 6.0%–6.4% [42–47 mmol/mol; pre–diabetes mellitus], and ≥6.5% [≥48 mmol/mol; diabetes mellitus]), in Cox regression models adjusted for known predictors of poor outcome. Patients with a history of diabetes mellitus (n=2907 [35%]) had a higher risk of the primary composite outcome of heart failure hospitalization or cardiovascular mortality compared with those without a history of diabetes mellitus: adjusted hazard ratio, 1.38; 95% confidence interval, 1.25 to 1.52; P<0.001. HbA1c measurement showed that an additional 1106 (13% of total) patients had undiagnosed diabetes mellitus and 2103 (25%) had pre–diabetes mellitus. The hazard ratio for patients with undiagnosed diabetes mellitus (HbA1c, >6.5%) and known diabetes mellitus compared with those with HbA1c<6.0% was 1.39 (1.17–1.64); P<0.001 and 1.64 (1.43–1.87); P<0.001, respectively. Patients with pre–diabetes mellitus were also at higher risk (hazard ratio, 1.27 [1.10–1.47]; P<0.001) compared with those with HbA1c<6.0%. The benefit of LCZ696 (sacubitril/valsartan) compared with enalapril was consistent across the range of HbA1c in the trial. Conclusions— In patients with heart failure and reduced ejection fraction, dysglycemia is common and pre–diabetes mellitus is associated with a higher risk of adverse cardiovascular outcomes (compared with patients with no diabetes mellitus and HbA1c <6.0%). LCZ696 was beneficial compared with enalapril

    Despite having lower body mass index (BMI) compared to other ethnic groups, Asians continue to develop significant metabolic diseases such as hypertension and diabetes. To evaluate the disparate association of BMI and risk of hypertension and diabetes in Asians. We retrospectively studied 150,753 adults from the 1985-2011 California Behavioral Risk Factor Survey. Trends in prevalence of obesity, hypertension, and diabetes were stratified by ethnicity. Multivariate logistic regression models evaluated the incremental effect of one unit BMI increase on risk of hypertension and diabetes and the disparate risks of hypertension and diabetes at different BMI thresholds. Asians had the lowest BMI among all groups. However, the impact of increasing BMI on risk of hypertension and diabetes was significantly greater in Asians. For each one unit increase in BMI, Asians were significantly more likely to have hypertension (OR 1.15; 95% CI 1.13-1.18) compared to non-Hispanic whites, blacks, and Hispanics. Similar trends were seen for diabetes (Asians: OR 1.15; 95% CI 1.13-1.18). The risk of hypertension in Asians with BMI ≥ 22 was similar to non-Hispanic whites with BMI ≥ 27 and blacks with BMI ≥ 28. The risk of diabetes in Asians with BMI ≥ 28 was similar to non-Hispanic whites with BMI ≥ 30. Despite lower overall BMI compared to other groups, weight gain in Asians is associated with significantly higher risks of hypertension and diabetes. Compared to other ethnic groups, similar risks of hypertension and diabetes are seen in Asians at much lower BMI.

    Background Gestational diabetes mellitus (GDM) is a form of diabetes that occurs in pregnancy. Although GDM usually resolves following birth, it is associated with significant morbidities for mother and baby both perinatally and in the long term. There is strong evidence to support treatment for GDM. However, there is little consensus on whether or not screening for GDM will improve maternal and infant health and if so, the most appropriate protocol to follow. Objectives To assess the effects of different methods of screening for gestational diabetes mellitus and maternal and infant outcomes. Search methods We searched the Cochrane Pregnancy and Childbirth Group’s Trials Register (April 2010). Selection criteria Randomised and quasi-randomised trials evaluating the effects of different methods of screening for gestational diabetes mellitus. Data collection and analysis Two review authors independently conducted data extraction and quality assessment. We resolved disagreements through discussion or through a third author. Main results We included four trials involving 3972 women were included in the review. One quasi-randomised trial compared risk factor screening with universal or routine screening by 50 g oral glucose challenge testing. Women in the universal screening group were more likely to be diagnosed with GDM (one trial, 3152 women, risk ratio (RR) 0.44 95% confidence interval (CI) 0.26 to 0.75). Infants of mothers in the risk factor screening group were born marginally earlier than infants of mothers in the routine screening group (one trial, 3152 women, mean difference −0.15 weeks, 95% CI −0.27 to −0.53). The remaining three trials evaluated different methods of administering a 50 g glucose load. Two small trials compared glucose monomer with glucose polymer testing, with one of these trials including a candy bar group. One trial compared a glucose solution with food. No differences in diagnosis of GDM were found between each comparison. Overall

    Overweight and obesity currently constitute a major threat to human well-being. Almost half of the female population are currently overweight. Pregnant overweight women are at risk of gestational diabetes affecting the health of the mother and the child, in both the short and long term. Notwithstanding the extensive scientific interest centred on the problem, research efforts have thus far been unable to devise preventive strategies. Recent scientific advances point to a gut microbiota dysbiosis, with ensuing low-grade inflammation as a contributing element, in obesity and its comorbidities. Such findings would suggest a role for specific probiotics in the search for preventive and therapeutic adjunct applications in gestational diabetes. The aim of the present paper was to critically review recent demonstrations of the role of intestinal microbes in immune and metabolic regulation, which could be exploited in nutritional management of pregnant women by probiotic bacteria. By modulating specific target functions, probiotic dietary intervention may exert clinical effects beyond the nutritional impact of food. As this approach in pregnancy is new, an overview of the role of gut microbiota in shaping host metabolism, together with the definition of probiotics are presented, and finally, specific targets and potential mechanisms for probiotics in pregnancy are discussed. Pregnancy appears to be the most critical stage for interventions aiming to reduce the risk of non-communicable disease in future generations, beyond the immediate dangers attributable to the health of the mother, labour and the neonate. Specific probiotic interventions during pregnancy provide an opportunity, therefore, to promote the health not only of the mother but also of the child.

    The aim of this study was to evaluate the healing of 3rd degree burn on diabetic rats submitted or not to treatment with Polarized Light. Diabetes mellitus (Streptozotocin, 60mg/kg) was induced on 45 male Wistar albinus rats and a third degree burn (1.5× 1.5cm) was created in the dorsum of each animal under general anesthesia. After a regular quarantine period, the animals were randomly distributed into three groups as follows: G1: control (no treatment, n =15); G2: Polarized Light (λ=400-2000nm, 20J/cm2) and G3: Polarized Light (λ=400-2000nm, 40J/cm2). The phototherapy performed on group G2 was Polarized Light dose 20J/cm2 and G3 was Polarized Light dose 40J/cm2 (Bioptron®, λ400-2000 nm, 40mW; 2.4J/cm2 per minute; Φ +/- 5.5 cm; Bioptron AG, Monchaltorf, Switzerland). The phototherapy started immediately post-burning and was repeated daily until the day before the animal death. The energy was applied transcutaneously respecting the focal distance of 10cm as recommended by the manufacturer. The dose was 20 or 40J/cm2 (4min 15s or 8min.and 30s). At each time point chosen (7, 14, and 21 days post-burning) and following macroscopic examination, each animal was killed by an overdose of general anesthesia. Slides were stained with HE, Sirius Red, and CK AE1/AE3 antibody. Qualitative and semi-quantitative analyses were performed under light microscopy. The animals submitted to phototherapy (20J/cm2) showed significant differences on regards revascularization and epithelialization. The use of 20J/cm2 was effective on improving the healing of third degree buns on diabetic animals at both early and late stages of the repair.

    Persons with type 1 and type 2 diabetes have increased fracture risk, attributed to deficits in the microarchitecture and strength of diabetic bone, thought to be mediated, in part, by the consequences of chronic hyperglycemia. Therefore, to examine the effects of a glucose-lowering SGLT2 inhibitor on blood glucose (BG) and bone homeostasis in a model of diabetic bone disease, male DBA/2J mice with or without streptozotocin (STZ)-induced hyperglycemia were fed chow containing the SGLT2 inhibitor, canagliflozin (CANA), or chow without drug, for 10weeks of therapy. Thereafter, serum bone biomarkers were measured, fracture resistance of cortical bone was assessed by μCT analysis and a three-point bending test of the femur, and vertebral bone strength was determined by compression testing. In the femur metaphysis and L6 vertebra, long-term diabetes (DM) induced deficits in trabecular bone microarchitecture. In the femur diaphysis, a decrease in cortical bone area, cortical thickness and minimal moment of inertia occurred in DM (p<0.0001, for all) while cortical porosity was increased (p<0.0001). These DM changes were associated with reduced fracture resistance (decreased material strength and toughness; decreased structural strength and rigidity; p<0.001 for all). Significant increases in PTH (p<0.0001), RatLAPs (p=0.0002), and urine calcium concentration (p<0.0001) were also seen in DM. Canagliflozin treatment improved BG in DM mice by ~35%, but did not improve microarchitectural parameters. Instead, in canagliflozin-treated diabetic mice, a further increase in RatLAPs was evident, possibly suggesting a drug-related intensification of bone resorption. Additionally, detrimental metaphyseal changes were noted in canagliflozin-treated control mice. Hence, diabetic bone disease was not favorably affected by canagliflozin treatment, perhaps due to insufficient glycemic improvement. Instead, in control mice, long-term exposure to SGLT2 inhibition was associated with

    Cardiovascular disease (CVD) risk assessment has changed substantially in recent years. While older guidelines considered diabetes a coronary disease risk equivalent, more recent guidelines recommend risk stratification on the basis of global risk scoring to target intensity of therapy. While patients with diabetes as a whole are at greater risk for CVD events, these patients may also benefit from risk stratification based on circulating biomarkers like high-sensitivity C-reactive protein, high-sensitivity cardiac troponin T, and N-terminal pro-B-type natriuretic peptide, as well as newer imaging modalities (coronary artery calcium, carotid intima-media thickness, and myocardial perfusion imaging). The addition of these CVD risk assessment modalities could play an important role for deciding how aggressive a physician should be with pharmacological therapy. Here, we discuss many of the current recommendations of CVD risk assessment in patients with diabetes including newer modalities for CVD risk assessment. PMID:27612474

    This study examined how adiposity influences racial/ethnic differences in diabetes incidence by exploring whether relations between anthropometric measures and incident diabetes vary by race/ethnicity. Data from the Multi-Ethnic Study of Atherosclerosis initiated in 2000 (n = 5,446 US men and women aged 45–84 years) were analyzed by using proportional hazards and Poisson regression. The diabetes incidence rate was 2/100 person-years (n = 479 cases). Interactions were present between race and anthropometry (P-interaction(race × body mass index) = 0.002). The slope of incident diabetes per anthropometric unit was greatest for Chinese, less for whites and Hispanics, and still less for blacks. For small waist, risk of incident diabetes was <1/100 person-years for all racial/ethnic groups. At intermediate waist levels, Chinese had the highest and whites the lowest rates of incident diabetes. At the respective 95th percentiles of waist circumference, risk of incident diabetes per 100 person-years was 3.9 for Chinese (104 cm), 3.5 for whites (121 cm), 5.0 for blacks (125 cm), and 5.3 for Hispanics (121 cm). Adiposity influenced relative diabetes occurrence across racial/ethnic groups, in that Chinese had a steeper diabetes risk per unit of adiposity. However, the generally low level of adiposity in Chinese led to a relatively low diabetes occurrence. PMID:20570825

    Foot complications (diabetic foot) are among the most serious and costly complications of diabetes mellitus. Amputation of all or part of a lower extremity is usually preceded by a foot ulcer. To prevent diabetic foot, an automatic non-invasive method to identify patients with diabetes who have a high risk of developing diabetic foot is proposed. To design the proposed method, information concerning social scope and self-care of 153 diabetic patients was presented to the K-means clustering algorithm, which divided the data into two groups: high risk and low risk of developing diabetic foot. In the operational stage, the Euclidian distance from the information vector to the centroids of each group of risk is used as criterion for classification. Both real and simulated data were used to evaluate the method in which promising results were achieved with accuracy of 0.97 ± 0.06 for simulated data and 0.68 ± 0.16 considering the classification of specialists as the gold standard for real data. The method requires a simple computational processing and can be useful for basic health units to triage diabetic patients helping the health-care team to reduce the number of cases of diabetic foot.

    Type 2 diabetes is associated with higher fracture risk. Diabetes-related conditions may account for this risk. Cardiovascular Health Study participants (N = 5641; 42.0% men; 15.5% black; 72.8±5.6 years) were followed 10.9 ± 4.6 years. Diabetes was defined as hypoglycemic medication use or fasting glucose (FG) ≥126 mg/dL. Peripheral artery disease (PAD) was defined as ankle-arm index <0.9. Incident hip fractures were from medical records. Crude hip fracture rates (/1000 person-years) were higher for diabetic vs. non-diabetic participants with BMI <25 (13.6, 95% CI: 8.9-20.2 versus 11.4, 95% CI: 10.1-12.9) and BMI ≥25 to <30 (8.3, 95% CI: 5.7-11.9 versus 6.6, 95% CI: 5.6-7.7), but similar for BMI ≥30. Adjusting for BMI, sex, race, and age, diabetes was related to fractures (HR = 1.34; 95% CI: 1.01-1.78). PAD (HR = 1.25 (95% CI: 0.92-1.57)) and longer walk time (HR = 1.07 (95% CI: 1.04-1.10)) modified the fracture risk in diabetes (HR = 1.17 (95% CI: 0.87-1.57)). Diabetes was associated with higher hip fracture risk after adjusting for BMI though this association was modified by diabetes-related conditions. PMID:21837239

    A suitable level of social perception about flood risk and awareness of Civil Protection Plans are critical to minimize disasters and damages due to flash floods. In order to improve risk perception, awareness and, as a result, the effectiveness of Civil Protection Plans, it is often required the implementation of communication plans. This research proposes a guide recommendation framework to enhance local population preparedness, prevention and response when a flash flood occurs. The research setting was a village (Navaluenga) located in Central Spain with 2,027 inhabitants. It is crossed by the Alberche river and Chorreron stream (both tributaries of the Tagus river), which are prone to flash floods. In a first phase, we assessed citizens' flash-flood risk perception and level of awareness regarding some key variables of the Civil Protection Plan. To this end, a questionnaire survey was designed and 254 adults, a sample representing roughly 12% of the population census, were interviewed. Responses were analysed, comparing awareness regarding preparedness and response actions with those previously defined in the Civil Protection Plan. In addition, we carried out a latent class cluster analysis aimed at identifying the different groups present among the respondents. Next, a risk communication plan was designed and implemented. It aimed to improve the understanding of flood risk among local people; and it comprises briefings, quiz-answers, contests of stories and flood images and intergenerational workshops. Finally, participants in the first phase were reached again and a new survey was performed. The results derived from these second questionnaires were statistically treated using the same approach of the first phase. Additionally, a t-test for paired samples and Pearson Chi-Square test was implemented in order to detect possible improvements in the perception and awareness. Preliminary results indicate that in Navaluenga there is a low social perception of flood

    Thrombosis is the leading cause of mortality globally. It is not only a complication but also a risk factor for progression of diabetes. However, alternative oral therapies and prophylaxis with less adverse effect for thrombosis have not been well studied. In this study, composite powder containing earthworm (CEP) was used and its fibrinolytic activity was measured. CEP was found to have a high urokinase-type plasminogen activator like activity in an in vitro assay. It also had significantly shortened euglobulin clot lysis time (ECLT) at 4 and 24 h after ingestion in Sprague Dawley rats. Zucker Diabetic Fatty rats were used to assess the effect of CEP on diabetes and diabetic nephropathy. After 10 weeks of feeding, CEP significantly shortened ECLT and attenuated HbA1c, hepatic lipid accumulation, and urinary albumin excretion and improved glomerular mesangial matrix score. Therefore, CEP may have beneficial effects on diabetes and diabetic nephropathy. PMID:27292184

    The highest incidence of Cholangiocarcinoma (CCA), a malignancy of bile duct epithelia, is in the Northeast of Thailand. The liver fluke, Opisthorchis viverrini, is the known risk factor for CCA development in this region. Approximately 1% of O. viverrini infected individuals develop CCA. There could be other factors that influence the cholangiocarcinogenesis particularly in the O. viverrini infected individuals. The global epidemiological studies of risk factors for CCA in non-O. viverrini related patients indicated diabetes mellitus (DM) as a risk factor of CCA. The molecular studies in many cancers indicated that high levels of glucose, insulin and an obese condition directly and indirectly enhanced growth of cancers. For O. viverrini associated CCA, there is limited information related to DM and CCA development. High mortality rates of CCA and DM, however, were reported in the same geographical areas of northeastern Thailand. Whether DM is a factor that enhances CCA development in O. viverrini infected individuals or promotes CCA progression are discussed in a perspective of epidemiological and molecular studies.

    We evaluated the effectiveness of the Salud y Bienestar program to deliver diabetes education in the Hispanic population in the United States. This program uses a community outreach model where community health promoters are trained and then they deliver education to other community members regarding diabetes disease, risk factors, and ways to prevent and control disease. This intervention applies a one-group pre- and post-test design to improve diabetes knowledge. The intervention carried out in the states of California, Texas, and Washington DC. A total of 1,413 participants were enrolled. Of these, 73% were females, 46% were 65 years or older, 59% were Mexican, 64% had at least elementary education, 56% had lived in the US for more than 20 years, and 38% participants were self-reported diabetic. Among diabetic participants, a significant improvement was observed on diabetes knowledge when comparing pre- and post-test scores (13.7 vs. 18.6, P < 0.001; Cohen's d = 1.2). Among non-diabetic participants, diabetes knowledge also increased significantly after one-single training session (12.9 vs. 18.2, P < 0.001; Cohen's d = 1.2). The Salud y Bienestar program conducted by community health workers was effective approach to improving diabetes knowledge in the Hispanic population.

    Background/Aim Dyslipidemia is a significant predictor of cardiovascular events and mortality in diabetes patients. The aim of this study is to estimate the prevalence rates, characteristics of dyslipidemia and their control in outpatient population in a Diabetic Centre. Methods A cross sectional prospective study design was used to collect data from 255 patients which included patient characteristics, past medical history of CVD, medications and parameters related to DM and cardiovascular risk factor control. Blood pressure and laboratory measurements for glycosylated hemoglobin and lipoprotein panel were recorded. Results Body mass index (BMI) of the dyslipidemic diabetic patients was significantly higher for females. In terms of age, duration of diabetes, family history, diabetes treatment offered did not differed significantly among genders. Clinical characteristics of HDL values were significantly higher for female in comparison to men (P = 0.02) whereas glycosylated hemoglobin and blood pressure appeared not to differ significantly. Among the three factors studied BMI, duration of diabetes mellitus and drug therapy on lipoprotein levels of diabetes patients, except for the influence of drug therapy which influenced significantly the total cholesterol level (P = 0.02). Number of females with normolipid were more than males (P = 0.009) and number of males with abnormal cholesterol and triglyceride patients were significantly more than females (0.0002). Conclusion Dyslipidemia among males were higher than females which could be a significant risk factor for causing low glycemic control culminating in cardiovascular events. Control of hyperglycaemia and other CVD risk factor appears to be suboptimal in Saudi Arabia. Addressing health system components such as providing medical staff training, incentive to health professionals and better patient education may improve quality of DM care.

    Abstract Increasing evidence suggests that certain types of cancers are more common in people with diabetes mellitus (DM). This study aimed to investigate the risk of skin cancer in patients with DM in Taiwan. In this retrospective cohort study using data from the Taiwan Longitudinal Health Insurance Research Database, the risk of developing overall skin cancer, including nonmelanoma skin cancer (NMSC) and melanoma, was compared by Poisson regression analysis and Cox regression analysis between the DM and non-DM cohorts. The DM cohort with newly diagnosed DM (n = 41,898) and a non-DM cohort were one-to-one matched by age, sex, index date, and comorbidities (coronary artery disease, hyperlipidemia, hypertension, chronic kidney disease, chronic obstructive pulmonary disease, and obesity). Compared with non-DM cohort statistically, for the people with DM aged ≥60 years, the incidence rates of overall skin cancer and NMSC were significantly higher (overall: DM/non-DM: number [n] = 99/76, incidence rate ratio [IRR] = 1.44, P = 0.02; NMSC: DM/non-DM: n = 94/66, IRR = 1.57, P = 0.005). By Cox regression analysis, the risk of developing overall skin cancer or NMSC was significantly higher after adjusting for sex, comorbidities, and overall diseases with immunosuppression status (overall: adjusted hazard ratio [AHR] = 1.46, P = 0.01; NMSC: AHR = 1.6, P = 0.003). Other significant risk factors were older males for skin cancer (overall: AHR = 1.68, P = 0.001; NMSC: AHR = 1.59, P = 0.004; melanoma: AHR = 3.25, P = 0.04), chronic obstructive pulmonary disease for NMSC (AHR = 1.44, P = 0.04), and coronary artery disease for melanoma (AHR = 4.22, P = 0.01). The risk of developing melanoma was lower in the DM cohort than in the non-DM cohort, but without significance (AHR = 0.56, P = 0.28; DM/non-DM: n = 5/10). The incidence rate and risk of developing overall skin cancer, including NMSC, was significantly higher in older adults with DM. Other significant risk factors for older

    Older patients with diabetes have a high risk of vascular complications. They have an increase of approximately 3 times for developing stroke compared with subjects without diabetes. In addition, up to 75-80% of deaths in diabetic patients are associated with major cardiovascular events including stroke. The risk of stroke is high within 5 years of diagnosis for type 2 diabetes is 9% (mortality 21%), that is more than doubles the rate for the general population. From observational registries in a collaborative stroke study in Mexico, we analyzed clinical data, risk factors, and outcome of 1182 diabetic patients with cerebral ischemia, with focus in elderly subjects. There was a high frequency of hyperglycemia during the acute phase of stroke: the median value was 140 mg/dL and 40% had values higher than 180 mg/dL. Clinical outcome was usually unfavorable in elderly stroke patients with diabetes: case fatality rate was 30% at 30 days and survivors had moderate to severe disability, usually as consequence of the propensity to develop more systemic medical complications during hospital stay. Primary stroke prevention studies in patients with diabetes reveal that tight control of glucose is not associated with reduction in stroke risk. Therefore, proper control of other vascular risk factors is mandatory in patients with diabetes, in particular of arterial hypertension.

    Background Oxidative capacity is decreased in type 2 diabetes. Whether decreased oxidative capacity is a cause or consequence of diabetes is unknown. Our purpose is to evaluate whether lactate, a marker of oxidative capacity, is associated with incident diabetes. Methods and Findings We conducted a case-cohort study in the Atherosclerosis Risk in Communities (ARIC) study at year 9 of follow-up. We evaluated lactate’s association with diabetes risk factors at baseline and estimated the hazard ratio for incident diabetes by quartiles of plasma lactate in 544 incident diabetic cases and 533 non-cases. Plasma lactate showed a graded positive relationship with fasting glucose and insulin (P<0.001). The relative hazard for incident diabetes increased across lactate quartiles (P-trend ≤0.001). Following adjustment for demographic factors, medical history, physical activity, adiposity, and serum lipids, the hazard ratio in the highest quartile was 2.05 times the hazard in the lowest quartile (95% CI: 1.28, 3.28). After including fasting glucose and insulin the association became non-significant. Conclusions Lactate, an indicator of oxidative capacity, predicts incident diabetes independent of many other risk factors and is strongly related to markers of insulin resistance. Future studies should evaluate the temporal relationship between elevated lactate and impaired fasting glucose and insulin resistance. PMID:23383072

    The aim of the study was to evaluate the phytochemistry and the effect of methanolic root extract (MREt) of Rauwolfia serpentina on alloxan-induced diabetic Wister male mice. Mice were divided in control (distilled water at 1 mL/kg) and alloxan-induced diabetic mice which subdivided into diabetic (distilled water at 1 mL/kg), negative (0.05% dimethyl sulfoxide at 1 mL/kg), positive (glibenclamide at 5 mg/kg) controls, and three test groups (MREt at 10, 30, and 60 mg/kg). All treatments were given orally for 14 days. Qualitatively MREt showed the presence of alkaloids, carbohydrates, flavonoids, glycosides, cardiac glycosides, phlobatannins, resins, saponins, steroids, tannins, and triterpenoids, while quantitatively extract was rich in total phenols. The flavonoids, saponins and alkaloids were also determined in root powder. MREt found effective in improving the body weights, glucose and insulin levels, insulin/glucose ratio, glycosylated and total hemoglobin in test groups as compared to diabetic control. Similarly, significantly decreased levels of total cholesterol, triglycerides, low-density lipoprotein (LDL-c), and very low-density lipoprotein (VLDL-c) cholesterols were found in test groups. Significant lipolysis with improved glycogenesis was also found in liver tissues of all test groups. ALT levels were found normal in all groups. Thus, MREt improves the glycemic, antiatherogenic, coronary risk, and cardioprotective indices in alloxan-induced diabetic mice. PMID:23365565

  3. Improving genetic risk prediction by leveraging pleiotropy

    An important task of human genetics studies is to predict accurately disease risks in individuals based on genetic markers, which allows for identifying individuals at high disease risks, and facilitating their disease treatment and prevention. Although hundreds of genome-wide association studies (GWAS) have been conducted on many complex human traits in recent years, there has been only limited success in translating these GWAS data into clinically useful risk prediction models. The predictive capability of GWAS data is largely bottlenecked by the available training sample size due to the presence of numerous variants carrying only small to modest effects. Recent studies have shown that different human traits may share common genetic bases. Therefore, an attractive strategy to increase the training sample size and hence improve the prediction accuracy is to integrate data from genetically correlated phenotypes. Yet the utility of genetic correlation in risk prediction has not been explored in the literature. In this paper, we analyzed GWAS data for bipolar and related disorders (BARD) and schizophrenia (SZ) with a bivariate ridge regression method, and found that jointly predicting the two phenotypes could substantially increase prediction accuracy as measured by the AUC (area under the receiver operating characteristic curve). We also found similar prediction accuracy improvements when we jointly analyzed GWAS data for Crohn’s disease (CD) and ulcerative colitis (UC). The empirical observations were substantiated through our comprehensive simulation studies, suggesting that a gain in prediction accuracy can be obtained by combining phenotypes with relatively high genetic correlations. Through both real data and simulation studies, we demonstrated pleiotropy can be leveraged as a valuable asset that opens up a new opportunity to improve genetic risk prediction in the future.

    Background Trials have demonstrated the efficacy of rigorous diet and physical activity promotion (D&PA) programs for adults at increased risk for type 2 diabetes to reduce diabetes incidence and improve measures of glycemia. Purpose To evaluate D&PA programs for individuals at increased risk for type 2 diabetes primarily to lower diabetes risk, lower body weight, and improve glycemia. Data Sources MEDLINE, Cochrane Central Register of Controlled Trials, CAB Abstracts, Global Health, and Ovid HealthStar from 1991 through 27 February 2015, with no language restriction. Study Selection 8 researchers screened articles for single group or comparative studies of combined D&PA programs with at least 2 sessions of at least 3 month duration in participants at increased risk for type 2 diabetes. Data Extraction 7 researchers extracted data—on study design, participant, intervention, outcome descriptions, and results—and assessed study quality. Data Synthesis 53 studies (30 D&PA vs. control, 13 more vs. less intensive, 13 in single programs) evaluated 66 programs. Compared with usual care, D&PA reduced type 2 diabetes incidence (RR = 0.59; 95% CI 0.51, 0.66; 16 studies), lowered body weight (net change = −2.2%; 95% CI −2.9, −1.4; 24 studies) and fasting blood glucose (net change = −0.12 mmol/L; 95% CI −0.20, −0.05; 17 studies), and improved other cardiometabolic risk factors. There was limited evidence for clinical events. More intensive programs were more effective. Limitations The wide variation in D&PA programs limited identification of features most relevant to effectiveness. Evidence on clinical outcomes and in children was sparse. Conclusions Combined D&PA promotion programs are effective to decrease diabetes incidence and improve cardiometabolic risk factors for patients at increased risk. More intensive programs are more effective. Primary Funding Source Centers for Disease Control and Prevention Community Preventive Services Task Force. PMID:26167912

    Background The dynamics of physiological and behavioral risk factors of diabetes in rural India is poorly understood. Using data from a health and demographic surveillance site of Birbhum district in West Bengal, India, this study aims to assess the risk factors associated with type 2 diabetes mellitus. Research design and methods A total of 7674 individuals aged ≥18 years participated in a cross-sectional study. Venous plasma glucose method was used for measuring and reporting glucose concentrations in blood, categorized as individuals with diabetes, pre-diabetes or impaired, and normoglycemic. Aside from a set of physiological and behavioral risk factors, a range of socioeconomic confounders of diabetes was computed. Bivariate analysis with χ2 test, and multivariate ordered logit regression methods were deployed to attain the study's objective. Results Overall 2.95% and 3.34% of study participants were diagnosed as individuals with diabetes and pre-diabetes or impaired, respectively. Compared to the poorest, the richest have higher probability (β: 0.730; 95% CI 0.378 to 1.083) of being diagnosed with diabetes. As compared to people with normal body mass index, overweight/obese people are more prone to being diagnosed with diabetes (β: 0.388; 95% CI 0.147 to 0.628). With a decreasing level of physical activity, people are more likely to be diagnosed with diabetes. Conclusions To curb the level of diabetes, this study recommends a culturally sensitive, focused intervention for the adoption of physical activity with more traditional dietary practices, to control the level of overweight/obesity. Attention should be paid to relatively older patients with diabetes or adults with pre-diabetes. PMID:27547420

    To determine the incidence rate of cardiovascular disease (CVD) and its association with conventional and less well-established risk factors in African Americans with diabetes, we studied 741 African Americans aged 45 to 64 years with diabetes, in the Atherosclerosis Risk in Communities (ARIC) study. Risk factors were measured from 1987 to 1989, and incident CVD (n = 143 coronary heart disease (CHD) or stroke events) was ascertained through 1998. The crude incidence rate (per 1000 person-years) of CVD was 22.5 (11.9 for CHD and 12.0 for stroke). After multivariate adjustments, total cholesterol, prevalent hypertension and current smoking were significantly and positively associated with incident CVD among these African Americans with diabetes. Among the non-conventional risk factors, serum creatinine, factor VIII, von Willebrand factor, and white blood cell count were positively and serum albumin negatively and independently associated with CVD incidence. Adjusted relative risks for highest versus lowest tertiles of these risk factors ranged from 1.77 to 2.13. This study confirms that the major risk factors (hypercholesterolemia, hypertension and smoking) are important determinants of CVD in African Americans with diabetes. In addition, several blood markers of hemostasis or inflammatory response and elevated serum creatinine also proved to be CVD risk factors in African Americans with diabetes. PMID:12510702

    Neighborhood-centered disease prevention programs have become a growing means of introducing baccalaureate nursing students to health care systems. This article reports diabetes and cardiovascular clinical outcomes and health behavior changes made following a 2-year baccalaureate community/public health clinical project and partnership with an urban Hispanic neighborhood. This pilot study used a pretest-posttest design without comparators. The healthy lifestyle consisted of health coaching, physical activity, and lifestyle modification. Thirty-eight women completed the 12-week program. Results revealed significant reductions in diabetes and cardiovascular total risk scores, glycated hemoglobin, body mass index, and physical activity (α = 0.05). Students gained learning opportunities in research and public health competencies, while providing clinical practice, research, and scholarship opportunities for nurse educators. Insights from these programs can help faculty, students, and communities identify new approaches that are consistent with the National Prevention Strategy and the Patient Protection and Affordable Care Act to improve diabetes and cardiovascular outcomes among Hispanic women.

    Abstract The aim of this study was to assess the overall and cause-specific incidences of diabetic hand syndromes (DHS) in patients with diabetes mellitus (DM) by using age and sex stratifications. The DM and control cohorts comprised 606,152 patients with DM and 609,970 age- and sex-matched subjects, respectively, who were followed up from 2000 to 2008. We estimated the incidence densities (IDs) of overall and cause-specific DHS, namely carpal tunnel syndrome (CTS), stenosing flexor tenosynovitis (SFT), limited joint mobility (LJM), and Dupuytren disease (DD), and calculated the hazard ratios (HRs) of DHS in relation to DM by using a Cox proportional hazards model with adjustment for potential confounders. Over a 9-year period, 51,207 patients with DM (8.45%) and 39,153 matched controls (6.42%) sought ambulatory care visits for various DHS, with an ID of 117.7 and 80.7 per 10,000 person-years, respectively. The highest cause-specific ID was observed for CTS, followed by SFT, LJM, and DD, regardless of the diabetic status. After adjustment for potential confounders, patients with DM had a significantly high HR of overall DHS (1.51, 95% confidence interval [CI] = 1.48–1.53). Men and women aged <35 years had the highest HR (2.64, 95% CI = 2.15–3.24 and 2.99, 95% CI = 2.55–3.50, respectively). Cause-specific analyses revealed that DM was more strongly associated with SFT (HR = 1.90, 95% CI = 1.86–1.95) and DD (HR = 1.83, 95% CI = 1.39–2.39) than with CTS (HR = 1.31, 95% CI = 1.28–1.34) and LJM (HR = 1.24, 95% CI = 1.13–1.35). Men and younger patients with DM have the highest risk of DHS. Certain hand syndromes, such as SFT and DD, were more strongly associated with DM than with other syndromes and require the attention of clinicians. PMID:26469895

    Rajan, Preethi; Greenberg, Harly

    2015-01-01

    Obstructive sleep apnea (OSA) is independently associated with cardiovascular and cardiometabolic risk in several large epidemiologic studies. OSA leads to several physiologic disturbances such as intermittent hypoxia, sleep fragmentation, and increase in autonomic tone. These disturbances have been associated with insulin resistance and type 2 diabetes mellitus (T2DM) in animal and human studies. Studies also suggest a bidirectional relationship between OSA and T2DM whereby T2DM itself might contribute to the features of OSA. Moreover, successful treatment of OSA may reduce these risks, although this is controversial. The purpose of this article is to review 1) the links and bidirectional associations between OSA and T2DM; 2) the pathogenic mechanisms that might link these two disease states; 3) the role of continuous positive airway pressure therapy in improving glucose tolerance, sensitivity, and resistance; and 4) the implications for clinical practice.

    2016-04-10

    The burden of diabetic foot disease (DFD) is expected to increase in the future. The incidence of DFD is still rising due to the high prevalence of DFD predisposing factors. DFD is multifactorial in nature; however most of the diabetic foot amputations are preceded by foot ulceration. Diabetic peripheral neuropathy (DPN) is a major risk factor for foot ulceration. DPN leads to loss of protective sensation resulting in continuous unconscious traumas. Patient education and detection of high risk foot are essential for the prevention of foot ulceration and amputation. Proper assessment of the diabetic foot ulceration and appropriate management ensure better prognosis. Management is based on revascularization procedures, wound debridement, treatment of infection and ulcer offloading. Management and type of dressing applied are tailored according to the type of wound and the foot condition. The scope of this review paper is to describe the diabetic foot syndrome starting from the evaluation of the foot at risk for ulceration, up to the new treatment modalities.

    Background While diabetes has been linked to several cancers in the gastrointestinal (GI) tract, findings have been mixed for sites other than colorectal and liver cancer. We used the Women's Health Initiative (WHI) data and conducted a comprehensive assessment of associations between diabetes and GI malignancy (esophagus, stomach, liver, biliary, pancreas, colon and rectal). Methods 145,765 postmenopausal women ages 50-79 enrolled in the WHI were followed for a mean 10.3 years. Cox proportional hazard regression models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for the association between GI cancers and diagnosed diabetes, including its duration and treatment. Results Diabetes at enrollment was associated with increased risk for liver (HR = 3.00 95% CI 1.68-5.36), pancreatic (HR=1.64 95% CI: 1.16-2.33), colon (HR=1.37 95% CI: 1.13-1.65) and rectal (HR=1.90, 95%CI: 1.24-2.90) cancer. Diabetes severity, assessed by duration or need for pharmacotherapy, appeared to have stronger links to risk of liver, pancreatic and rectal cancer, but not colon cancer. There was no statistically significant association of diabetes with biliary, esophageal and stomach cancers. Conclusion Type 2 diabetes is associated with a significantly increased risk of cancers of the liver, pancreas, colon and rectum in postmenopausal women. Diabetes severity may further increase risk of pancreatic, liver and rectal cancer. Impact This study confirmed that diabetes increases risk of cancers of the liver, pancreas, colon and rectum. The suggestion that diabetes severity further increases these cancer risks requires future studies. PMID:22622863

    Previous studies have revealed that diabetic patients have a decline in immunity and an increased risk of infections, and this may be associated with poor micronutrient status. The aim of this study was to measure the effect of dietary supplements on risk of infection in patients with type 2 diabetes mellitus. One hundred patients with type 2 diabetes mellitus were randomly assigned to receive an oral dose of daily B-group vitamins and antioxidant vitamins (n = 50) or an identical placebo (n = 50) daily for 90 days. Patients had baseline, three and 12 month assessment for nutritional status, fruits and vegetables intake, physical activity and self-reported infections. Supplementation with antioxidants and B-group vitamins significantly increased the plasma concentration of vitamin E and folate and reduced homocysteine in the intervention group (p-values were 0.006, 0.001 and 0.657, respectively). The number of infections reported by the treatment group after three months of supplements was less than that reported by the placebo group, 9 (27%) vs. 15 (36%) (p = 0.623). Corresponding numbers of infections at 12 months were 25 (67.5%) and 27 (56.3%), respectively (p = 0.488). Up to 90% of the diabetic patients were either overweight or obese with a sedentary life style, and their body weight increased further during three months of follow up. The study showed that multivitamin supplements improved vitamin blood concentrations; however, this did not reduce the number of infections in diabetic patients.

    The goal of this study was to assess the effect of the intermittent combination of an antiresorptive agent (calcitonin) and an anabolic agent (vitamin D3) on treating the detrimental effects of Type 1 diabetes mellitus (DM) on mandibular bone formation and growth. Forty 3-week-old male Wistar rats were divided into four groups: the control group (normal rats), the control C+D group (normal rats injected with calcitonin and vitamin D3), the diabetic C+D group (diabetic rats injected with calcitonin and vitamin D3) and the diabetic group (uncontrolled diabetic rats). An experimental DM condition was induced in the male Wistar rats in the diabetic and diabetic C+D groups using a single dose of 60 mg·kg(-1) body weight of streptozotocin. Calcitonin and vitamin D3 were simultaneously injected in the rats of the control C+D and diabetic C+D groups. All rats were killed after 4 weeks, and the right mandibles were evaluated by micro-computed tomography and histomorphometric analysis. Diabetic rats showed a significant deterioration in bone quality and bone formation (diabetic group). By contrast, with the injection of calcitonin and vitamin D3, both bone parameters and bone formation significantly improved (diabetic C+D group) (P < 0.05). These findings suggest that these two hormones might potentially improve various bone properties. PMID:27025264

    The present paper updates the Clinical Practice Recommendations for the management of cardiovascular risk factors (CVRF) in diabetes mellitus. This is a medical consensus agreed by an independent panel of experts from the Spanish Society of Diabetes (SED). Several consensuses have been proposed by scientific and medical Societies to achieve clinical goals. However, the risk score for general population may lack sensitivity for individual assessment or for particular groups at risk, such as diabetics. Traditional risk factors together with non-traditional factors are reviewed throughout this paper. Intervention strategies for managing CVRF in the diabetic patient are reviewed in detail: balanced food intake, weight reduction, physical exercise, smoking cessation, reduction in HbA1c, therapy for high blood pressure, obesity, lipid disorders, and platelet anti-aggregation. It is hoped that these guidelines can help clinicians in the decisions of their clinical activity. This regular update by the SED Cardiovascular Disease Group of the most relevant concepts, and of greater practical and realistic clinical interest, is presented in order to reduce CVR of diabetics.

    Objective: The aims of the study were to investigate the prevalence of pre-diabetes and explore its associated risk factors in rural areas of Ningbo, China. Methods: A cross-sectional survey was conducted with 4583 adult residents in rural areas of Ningbo, China between March and May 2013. The survey used a multi-stage, stratified, cluster sampling method. Data collected included demographics and medical history, anthropometric measurements, blood pressure, blood lipid, and plasma glucose. After at least 10 h of overnight fasting, participants underwent an oral glucose tolerance test (OGTT) to identify pre-diabetes. Univariate and multivariate logistic regression analyses were used to evaluate the associated risk factors for pre-diabetes, and to estimate the effect of interaction between the factors. Results: There were 1307 survey participants having pre-diabetes (28.52%) and the age-standardized prevalence was 30.53%. Multivariate logistic regression results showed that overweight/obesity, hypertension, and higher triglycerides were the risk factors for developing pre-diabetes. There were positive interactions between overweight/obesity and triglycerides, and also between hypertension and triglycerides on the multiplicative scale, suggesting that they synergistically influenced the development of pre-diabetes. Conclusions: The rural areas in Ningbo had a high prevalence of pre-diabetes. Overweight and obesity, hypertension, and elevated triglycerides were the major risk factors. There is a need of early intervention for preventing pre-diabetes. PMID:27517947

    Background Eucommia bark, Eucommia ulmoides Oliver barks (Du-Zhong in Mandarin), is an herb used for renal dysfunction in Chinese traditional medicine. In an attempt to develop this herb as a treatment for diabetic nephropathy (DN), we investigated the effects of Du-Zhong on renal dysfunction in type 1-like diabetic rats. Methods Streptozotocin (STZ) was used to induce type 1-like diabetes in rats (STZ-diabetic rats). In addition to hyperglycemia, STZ-diabetic rats showed significant nephropathy, including higher plasma levels of blood urea nitrogen, creatinine, and renal fibrosis. Western blot analysis of renal cortical tissue was applied to characterize the changes in potential signals related to nephropathy. Results Oral administration of Du-Zhong (1 g/kg/day) to STZ-diabetic rats for 20 days not only decreased the plasma levels of blood urea nitrogen and creatinine but also improved renal fibrosis, whereas the plasma glucose level was not changed. The higher expressions of protein levels of transforming growth factor-beta (TGF-β) and connective tissue growth factor in diabetic rats were markedly attenuated by Du-Zhong. The increased phosphorylation of Smad2/3 in STZ-diabetic rats was also reduced by Du-Zhong. However, Du-Zhong cannot reverse the hyperglycemia-induced overproduction of signal transducers and activators of transcription 3 in the diabetic kidney. Conclusion Oral administration of Du-Zhong improves STZ-induced DN in rats by inhibiting TGF-β/Smad signaling and suppressing TGF-β/connective tissue growth factor expression. Therefore, active principle from Du-Zhong is suitable to develop as new agent for DN in the future. PMID:27041999

    Survival in type 1 diabetes has improved, but the impact on life expectancy in the U.S. type 1 diabetes population is not well established. Our objective was to estimate the life expectancy of the Pittsburgh Epidemiology of Diabetes Complications (EDC) study cohort and quantify improvements by comparing two subcohorts based on year of diabetes diagnosis (1950-1964 [n = 390] vs. 1965-1980 [n = 543]). The EDC study is a prospective cohort study of 933 participants with childhood-onset (aged <17 years) type 1 diabetes diagnosed at Children's Hospital of Pittsburgh from 1950 to 1980. Mortality ascertainment was censored 31 December 2009. Abridged cohort life tables were constructed to calculate life expectancy. Death occurred in 237 (60.8%) of the 1950-1964 subcohort compared with 88 (16.2%) of the 1965-1980 subcohort. The life expectancy at birth for those diagnosed 1965-1980 was ~15 years greater than participants diagnosed 1950-1964 (68.8 [95% CI 64.7-72.8] vs. 53.4 [50.8-56.0] years, respectively) (P < 0.0001); this difference persisted regardless of sex or pubertal status at diagnosis. This improvement in life expectancy emphasizes the need for insurance companies to update analysis of the life expectancy of those with childhood-onset type 1 diabetes because weighting of insurance premiums is based on outdated estimates.

    Diabetes impairs the ability to heal cutaneous wounds, leading to hospitalization, amputations, and death. Patients with diabetes experience elevated levels of plasminogen activator inhibitor 1 (PAI-1), regardless of their glycemic control. It has been demonstrated that PAI-1-deficient mice exhibit improved cutaneous wound healing, and that PAI-1 inhibition improves skeletal muscle repair in mice with type 1 diabetes mellitus, leading us to hypothesize that pharmacologically mediated reductions in PAI-1 using PAI-039 would normalize cutaneous wound healing in streptozotocin (STZ)-induced diabetic (STZ-diabetic) mice. To simulate the human condition of variations in wound care, wounds were aggravated or minimally handled postinjury. Following cutaneous injury, PAI-039 was orally administered twice daily for 10 days. Compared with nondiabetic mice, wounds in STZ-diabetic mice healed more slowly. Wound site aggravation exacerbated this deficit. PAI-1 inhibition had no effect on dermal collagen levels or wound bed size. PAI-039 treatment failed to improve angiogenesis in the wounds of STZ-diabetic mice and blunted angiogenesis in the wounds of nondiabetic mice. Importantly, PAI-039 treatment significantly improved epidermal cellular migration and wound re-epithelialization compared with vehicle-treated STZ-diabetic mice. These findings support the use of PAI-039 as a novel therapeutic agent to improve diabetic wound closure and demonstrate the primary mechanism of its action to be related to epidermal closure.

    Background The prevalence of type 2 diabetes (T2D) is increasing in the Middle East. However, the genetic risk factors for T2D in the Middle Eastern populations are not known, as the majority of studies of genetic risk for T2D are in Europeans and Asians. Methods All subjects were ≥3 generation Qataris. Cases with T2D (n = 1,124) and controls (n = 590) were randomly recruited and assigned to the 3 known Qatari genetic subpopulations [Bedouin (Q1), Persian/South Asian (Q2) and African (Q3)]. Subjects underwent genotyping for 37 single nucleotide polymorphisms (SNPs) in 29 genes known to be associated with T2D in Europeans and/or Asian populations, and an additional 27 tag SNPs related to these susceptibility loci. Pre-study power analysis suggested that with the known incidence of T2D in adult Qataris (22%), the study population size would be sufficient to detect significant differences if the SNPs were risk factors among Qataris, assuming that the odds ratio (OR) for T2D SNPs in Qatari’s is greater than or equal to the SNP with highest known OR in other populations. Results Haplotype analysis demonstrated that Qatari haplotypes in the region of known T2D risk alleles in Q1 and Q2 genetic subpopulations were similar to European haplotypes. After Benjamini-Hochberg adjustment for multiple testing, only two SNPs (rs7903146 and rs4506565), both associated with transcription factor 7-like 2 (TCF7L2), achieved statistical significance in the whole study population. When T2D subjects and control subjects were assigned to the known 3 Qatari subpopulations, and analyzed individually and with the Q1 and Q2 genetic subpopulations combined, one of these SNPs (rs4506565) was also significant in the admixed group. No other SNPs associated with T2D in all Qataris or individual genetic subpopulations. Conclusions With the caveats of the power analysis, the European/Asian T2D SNPs do not contribute significantly to the high prevalence of T2D in the Qatari population, suggesting

    Peripheral neuropathies are a major cause of morbidity in patients with diabetes mellitus. Up to now, drugs for improving the impaired nerve functions has been lacking for diabetic neuropathy. The antioxidant and neuroprotective effects of luteolin make it an attractive candidate for diabetic neuropathy. The present study was designed to investigate the putative beneficial effect of luteolin on diabetic neuropathy. Diabetic rats were intraperitoneally treated with daily luteolin (50 mg/kg, 100 mg/kg and 200 mg/kg) or vehicle for 3 weeks from the 28(th) day after streptozotocin injection. Behavioral, electrophysiological and biochemical studies were performed to evaluate the effect of luteolin on the impaired nerve functions in diabetic neuropathy. It was found that luteolin dose dependently alleviated abnormal sensation, improved nerve conduction velocities and nerve blood flow in diabetic rats. Biochanical analysis showed that luteolin significantly lowered the reactive oxygen species production and malondialdehyde level, as well as increased antioxidants activities in a dose dependent manner. In addition, luteolin significantly up-regulated the protein levels of nuclear factor-E2-related factor-2 (Nrf2) and heme oxygenase-1 (HO-1) in diabetic nerves. Taken together, luteolin is capable of improving diabetes-induced deficit in motor and sensory functions, which could be attributable, at least in part, to its Nrf2-dependent antioxidant capacity. The findings in the present study highlight the therapeutic value of luteolin for diabetic neuropathy.

    The main aim of this study is to determine the prevalence and risk factors of ischemic stroke among diabetic patients registered in the Saudi National Diabetes Registry (SNDR) database. A cross-sectional sample of 62,681 diabetic patients aged ≥25 years was used to calculate ischemic stroke prevalence and its risk factors. Univariate and multivariate logistic regression analyses were used to assess the roles of different risk factors. The prevalence of ischemic stroke was 4.42% and was higher in the older age group with longer diabetes duration. Poor glycemic control and the presence of chronic diabetes complications were associated with a high risk of ischemic stroke. History of smoking and type 2 diabetes were more frequent among stroke patients. Obesity significantly decreased the risk for ischemic stroke. Regression analysis for ischemic stroke risk factors proved that age ≥45 years, male gender, hypertension, coronary artery disease (CAD), diabetes duration ≥10 years, insulin use, and hyperlipidemia were significant independent risk factors for ischemic stroke. We conclude that ischemic stroke is prevalent among diabetic individuals, particularly among those with type 2 diabetes. Good glycemic, hypertension, and hyperlipidemia control, in addition to smoking cessation, are the cornerstones to achieve a significant reduction in ischemic stroke risk. PMID:26989695

    The objective of this study was to compare the amount of self-reported physical activity, alcohol and tobacco use in a large sample of adults with type 1 diabetes and non-diabetic subjects. A second aim is to test the hypothesis that these lifestyle risk factors are associated cross-sectionally with coronary artery calcification. In 2000-2002, the Coronary Artery Calcification in Type 1 Diabetes (CACTI) study applied validated questionnaires for smoking, alcohol and physical activity to 582 type 1 diabetes subjects and 724 non-diabetic subjects. More type 1 diabetes subjects reported current smoking than non-diabetic subjects (12.3% versus 8.6%, p=0.027). Overall, reported physical activity did not differ by diabetes status (p=0.79). More type 1 diabetes subjects reported never having consumed alcohol (10% versus 4%, p<0.0001) and those who drank consumed less alcohol (p=0.0015) than non-diabetic subjects. Physical activity and smoking were significantly associated with the presence of coronary artery calcification (adjusted OR=0.9, 95% CI: 0.8-0.996, p=0.045, and OR=1.7, CI: 1.1-2.6, p=0.03, respectively). Type 1 diabetes was independently associated with increased odds of coronary artery calcification (OR=3.5, 95% CI: 2.5-5.0, p<0.0001). Differences exist in lifestyle-related cardiovascular risk factors in men and women with type 1 diabetes compared with non-diabetic subjects in the CACTI study. PMID:20368221

    Treatment of stroke with bone marrow stromal cells (BMSC) significantly enhances brain remodeling and improves neurological function in non-diabetic stroke rats. Diabetes is a major risk factor for stroke and induces neurovascular changes which may impact stroke therapy. Thus, it is necessary to test our hypothesis that the treatment of stroke with BMSC has therapeutic efficacy in the most common form of diabetes, type 2 diabetes mellitus (T2DM). T2DM was induced in adult male Wistar rats by administration of a high fat diet in combination with a single intraperitoneal injection (35mg/kg) of streptozotocin. These rats were then subjected to 2h of middle cerebral artery occlusion (MCAo). T2DM rats received BMSC (5x106, n = 8) or an equal volume of phosphate-buffered saline (PBS) (n = 8) via tail-vein injection at 3 days after MCAo. MRI was performed one day and then weekly for 5 weeks post MCAo for all rats. Compared with vehicle treated control T2DM rats, BMSC treatment of stroke in T2DM rats significantly (p<0.05) decreased blood-brain barrier disruption starting at 1 week post stroke measured using contrast enhanced T1-weighted imaging with gadopentetate, and reduced cerebral hemorrhagic spots starting at 3 weeks post stroke measured using susceptibility weighted imaging, although BMSC treatment did not reduce the ischemic lesion volumes as demarcated by T2 maps. These MRI measurements were consistent with histological data. Thus, BMSC treatment of stroke in T2DM rats initiated at 3 days after stroke significantly reduced ischemic vascular damage, although BMSC treatment did not change infarction volume in T2DM rats, measured by MRI.

    Diabetes, which is a metabolic disorder with multiple comorbidities, increases the risk of cardiovascular disease. Although it was once assumed that controlling plasma glucose levels would reduce diabetes-related morbidity and mortality, recent trials have demonstrated that this is not consistently the case. Data from large, well-designed trials suggest that intensive glycemic therapy may be useful in preventing cardiovascular events if initiated early in the disease course, but may be harmful or not useful if applied to high-risk patients with a longer history of diabetes. Furthermore, the cardiovascular safety of existing individual antihyperglycemic agents remains largely unknown. We review the relationship between glycemic control targets and cardiovascular outcomes, as well as the current understanding of the cardiovascular effects of existing glucose-lowering therapies. This information has affected recommendations for diabetes care in Japan and the United States differently, and supports a more comprehensive and prospective approach to cardiovascular safety assessments of diabetes therapies in the future. Results from ongoing cardiovascular outcomes trials of diabetes medications may help to define optimal glucose-lowering strategies for patients at high risk of cardiovascular complications. Until then, glycemic control targets and the medications used to achieve them should be individualized according to each patient's age, duration of diabetes, risk of hypoglycemia, risk of cardiovascular complications, and life expectancy.

    Dietary factors are important predictors for the risk of diabetes type 2. Increased consumption of fibre-rich foods, fruits and vegetables as well as limited amounts of total and saturated fats are essential elements in the prevention of diabetes type 2. The association between these dietary factors and the appearance of diabetes was not only present in cohort studies but were also major elements in the dietary part of the two large diabetes prevention trials (Finnish Diabetes Prevention Study, Diabetes Prevention Program). There is also strong evidence for a relation between obesity and total fat intake and the incidence of certain types of cancers. There is a significant correlation between total fat intake and the risk of cancer; however, it is much weaker than that of the effect of red meat. Recommendations to decrease red meat intake, particularly processed meat, may decrease the risk of colorectal and prostate cancer and may have beneficial effects on breast cancer as well, although this evidence is less compelling. Overall, recommendations focused on controlling or reducing body weight by regular physical activity and avoidance of excessive energy intake from all sources, particularly from fat and saturated fats, by increasing consumption of fibre-rich carbohydrates, vegetables and fruits are effective in decreasing the risk for type 2 diabetes by more than 50% in high-risk individuals. Similar dietary patterns are likely to diminish the manifestation of certain forms of cancers. These conclusions are in agreement with current recommendations for cancer prevention as propagated by the American Cancer Society.

    Background Suboptimal lifestyle factors in combination with genetic susceptibility contribute to cardiovascular disease and type 2 diabetes risk among Latinos. We describe a community–academic collaboration that developed and explored the feasibility of implementing a socioculturally tailored, healthy lifestyle intervention integrating genomics and family history education to reduce risk of cardiovascular disease and type 2 diabetes among Latinos. Community Context The community-based participatory research was conducted with communities in Kentucky, which has a rapidly growing Latino population. This growth underscores the need for socioculturally appropriate health resources. Methods Su Corazon, Su Vida (Your Heart, Your Life) is a Spanish-language, healthy lifestyle educational program to reduce cardiovascular disease and type 2 diabetes risk among Latinos. Twenty natural leaders from an urban Latino community in Kentucky participated in sociocultural tailoring of the program and development of a genomics and family history module. The tailored program was presented to 22 participants to explore implementation feasibility and assess appropriateness for community use. Preintervention and postintervention assessments of genomic knowledge and lifestyle behaviors and qualitative postintervention evaluations were conducted. Outcomes Postintervention improvements in health-promoting lifestyle choices and genomic knowledge specific to cardiovascular disease and type 2 diabetes suggested that the program may be effective in reducing risk. Feedback indicated the program was socioculturally acceptable and responsive to community needs. Interpretation These findings indicated that a tailored healthy lifestyle program integrating genomics and family history education was socioculturally appropriate and may feasibly be implemented to reduce cardiovascular disease and type 2 diabetes risk in a Latino community with limited health care resources.

    Objectives. We evaluated cardiovascular disease (CVD) risk factors in American Indians/Alaska Natives (AI/ANs) with diabetes in the Special Diabetes Program for Indians Healthy Heart (SDPI-HH) Demonstration Project. Methods. Multidisciplinary teams implemented an intensive case management intervention among 30 health care programs serving 138 tribes. The project recruited 3373 participants, with and without current CVD, between 2006 and 2009. We examined data collected at baseline and 1 year later to determine whether improvements occurred in CVD risk factors and in Framingham coronary heart disease (CHD) risk scores, aspirin use, and smoking status. Results. A1c levels decreased an average of 0.2% (P < .001). Systolic and diastolic blood pressure, low-density lipoprotein (LDL) cholesterol, and triglyceride levels decreased, with the largest significant reduction in LDL cholesterol (∆ = −5.29 mg/dL; P < .001). Average Framingham CHD risk scores also decreased significantly. Aspirin therapy increased significantly, and smoking decreased. Participants with more case management visits had significantly greater reductions in LDL cholesterol and A1c values. Conclusions. SDPI-HH successfully translated an intensive case management intervention. Creative retention strategies and an improved understanding of organizational challenges are needed for future Indian health translational efforts. PMID:25211728

    Treatment strategies for foot at risk and diabetic foot are mainly preventive. Studies describing demographic data, clinical and impacting factors continue to be, however, scarce. Our objective was to determine the epidemiological presentation of diabetic foot and understand whether there were easily assessable variables capable of predicting the development of diabetic foot. This was a retrospective study of 496 patients with established foot at risk or diabetic foot, who were evaluated based on age, gender, type and duration of diabetes, foot at risk classification, and the presence of deformities, ulceration, and amputation. The presence of deformities, ulceration, and amputation was recorded in 45.9, 25.3, and 12.9 % of patients, respectively. As for diabetic foot classification, the great majority of our cohort had diabetic neuropathy (92.9 %). Approximately 30 % had neuro-ischemic disease and only 7.1 % had ischemic disease alone. Sixty-two percent of patients presented neuropathy with no signs of arteriopathy. Foot classification was as a significant predictor for the presence of ulcer (p = 0.009; OR = 3.2; 95 % CI = 1.18-7.3). Only male gender was a significant predictor for ulceration (p < 0.001). Predictors of amputation were male gender (p < 0.001; OR = 3.44 95 % CI = 1.81-6.56) and neuro-ischemic diabetic foot (p < 0.049; OR = 4.6; 95 % CI = 1.01-20.9). The predictors for diabetic foot were male gender and the presence of neuropathy. The combination of neuropathy and peripheral vascular disease adds significantly to the risk for amputation among patients with the diabetic foot syndrome. Men, presenting combined risk factors, should be a group receiving special attention and in the foot clinic, due to their potentially worse evolution.

    Background Whether HbA1c is a predictor of end-stage renal disease (ESRD) in type 2 diabetes patients remains unclear. This study evaluated relationship between HbA1c and ESRD in Chinese patients with type 2 diabetes. Methods Patients aged ≥ 30 years who were free of ESRD (n = 51 681) were included from National Diabetes Care Management Program from 2002–2003. Extended Cox proportional hazard model with competing risk of death served to evaluate association between HbA1c level and ESRD. Results A total of 2613 (5.06%) people developed ESRD during a follow-up period of 8.1 years. Overall incidence rate of ESRD was 6.26 per 1000 person-years. Patients with high levels of HbA1c had a high incidence rate of ESRD, from 4.29 for HbA1c of  6.0%–6.9% to 10.33 for HbA1c ≥ 10.0% per 1000 person-years. Patients with HbA1c < 6.0% particularly had a slightly higher ESRD incidence (4.34 per 1000 person-years) than those with HbA1c  of 6.0%–6.9%. A J-shaped relationship between HbA1c level and ESRD risk was observed. After adjustment, patients with HbA1c < 6.0% and ≥ 10.0% exhibited an increased risk of ESRD (HR: 1.99, 95% CI: 1.62–2.44; HR: 4.42, 95% CI: 3.80–5.14, respectively) compared with those with HbA1c of 6.0%–6.9%. Conclusions Diabetes care has focused on preventing hyperglycemia, but not hypoglycemia. Our study revealed that HbA1c level ≥ 7.0% was linked with increased ESRD risk in type 2 diabetes patients, and that HbA1c < 6.0% also had the potential to increase ESRD risk. Our study provides epidemiological evidence that appropriate glycemic control is essential for diabetes care to meet HbA1c targets and improve outcomes without increasing the risk to this population. Clinicians need to pay attention to HbA1c results on diabetic nephropathy. PMID:26098901

    Curcumin is a phytocompound found in the root of turmeric, a common herbal ingredient in many Asian cuisines. The compound contains anti-inflammatory activity, which is mediated through an up-regulation of adiponectin and reduction of leptin. Consumption of curcumin was shown to prevent some deteriorative conditions caused by inflammation, such as ulcerative colitis, rheumatoid arthritis and esophagitis, and so on. Inflammation-associated cardiovascular conditions such as atherosclerosis are common in diabetes patients. The anti-inflammation effect of curcumin might be beneficial to prevent such condition in these patients. We aim to evaluate an antiatherosclerosis effect of curcumin in diabetes patients. Effects of curcumin on risk factors for atherosclerosis were investigated in a 6-month randomized, double-blinded and placebo-controlled clinical trial that included subjects diagnosed with type 2 diabetes. An atherosclerosis parameter, the pulse wave velocity, and other metabolic parameters in patients treated with placebo and curcumin were compared. Our results showed that curcumin intervention significantly reduced pulse wave velocity, increased level of serum adiponectin and decreased level of leptin. These results are associated with reduced levels of homeostasis model assessment-insulin resistance, triglyceride, uric acid, visceral fat and total body fat. In summary, a 6-month curcumin intervention in type 2 diabetic population lowered the atherogenic risks. In addition, the extract helped to improve relevant metabolic profiles in this high-risk population. PMID:24445038

    Impaired skin wound healing is a major medical problem in diabetic subjects. Kinins exert a number of vascular and other actions limiting organ damage in ischaemia or diabetes, but their role in skin injury is unknown. We investigated, through pharmacological manipulation of bradykinin B1 and B2 receptors (B1R and B2R respectively), the role of kinins in wound healing in non-diabetic and diabetic mice. Using two mouse models of diabetes (streptozotocin-induced and db/db mice) and non-diabetic mice, we assessed the effect of kinin receptor activation or inhibition by subtype-selective pharmacological agonists (B1R and B2R) and antagonist (B2R) on healing of experimental skin wounds. We also studied effects of agonists and antagonist on keratinocytes and fibroblasts in vitro. Levels of Bdkrb1 (encoding B1R) and Bdkrb2 (encoding B2R) mRNAs increased 1-2-fold in healthy and wounded diabetic skin compared with in non-diabetic skin. Diabetes delayed wound healing. The B1R agonist had no effect on wound healing. In contrast, the B2R agonist impaired wound repair in both non-diabetic and diabetic mice, inducing skin disorganization and epidermis thickening. In vitro, B2R activation unbalanced fibroblast/keratinocyte proliferation and increased keratinocyte migration. These effects were abolished by co-administration of B2R antagonist. Interestingly, in the two mouse models of diabetes, the B2R antagonist administered alone normalized wound healing. This effect was associated with the induction of Ccl2 (encoding monocyte chemoattractant protein 1)/Tnf (encoding tumour necrosis factor α) mRNAs. Thus stimulation of kinin B2 receptor impairs skin wound healing in mice. B2R activation occurs in the diabetic skin and delays wound healing. B2R blockade improves skin wound healing in diabetic mice and is a potential therapeutic approach to diabetic ulcers.

    Diabetes mellitus (DM) is a major worldwide health problem and its prevalence has been rapidly increasing in the last century. It is caused by defects in insulin secretion or insulin action or both, leading to hyperglycemia. Of the various types of DM, type 2 occurs most frequently. Multiple genes and their interactions are involved in the insulin secretion pathway. Insulin secretion is mediated through the ATP-sensitive potassium (KATP) channel in pancreatic beta cells. This channel is a heteromeric protein, composed of four inward-rectifier potassium ion channel (Kir6.2) tetramers, which form the pore of the KATP channel, as well as sulfonylurea receptor 1 subunits surrounding the pore. Kir6.2 is encoded by the potassium inwardly rectifying channel, subfamily J, member 11 (KCNJ11) gene, a member of the potassium channel genes. Numerous studies have reported the involvement of single nucleotide polymorphisms of the KCNJ11 gene and their interactions in the susceptibility to DM. This review discusses the current evidence for the contribution of common KCNJ11 genetic variants to the development of DM. Future studies should concentrate on understanding the exact role played by these risk variants in the development of DM. PMID:26448950

    Genes and mechanisms involved in autoimmune diseases, affecting approximately 5% of human population, remain still obscure but there is accumulating evidence that common genetic factors might predispose to multiple autoimmune disorders. STAT4, a transcription factor transmitting signals induced by several key cytokines, has recently been identified as a genetic risk factor for rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and Sjögren's disease (SD), thus indicating that multiple autoimmune diseases may share common biochemical pathways that lead to immune deregulation. Here we demonstrate for the first time, in a genetically homogeneous population, the association of the STAT4 rs7574865 G/T polymorphism, which has been shown to be associated with these autoimmune diseases, with susceptibility to type 1 diabetes (T1D). The susceptibility is associated with a significant increase of the frequency of the T allele (p = 0.0012, two-tailed chi(2), OR = 1.94, 95% CI = 1.29-2.91) in this single-nucleotide polymorphism (SNP). We also present an indication for association with Wegener's granulomatosis. These findings suggest that this variant form of STAT4 may have a putative key role in the development of a variety of autoimmune diseases, probably because of signaling defects that it causes in the IL-12 pathway.

    We report a case of calcaneal osteomyelitis that was surgically resected from a patient with diabetes and peripheral vascular disease. A 91-year-old male with history of type 2 diabetes, peripheral vascular disease, balloon angioplasty, and recent (2 months ago) stent of the superficial femoral artery presented to the emergency department with a left heel wound infection probed to bone. The patient reported having been on intravenous Zosyn for several months via an outside infectious disease provider for clinical suspicion of osteomyelitis, but noted no improvement. This report includes information regarding the clinical examination and imaging findings, which were used to assess this high-risk patient. Our patient underwent a partial calcanectomy and completed a 6-week course of intravenous antibiotics. The purpose of this case report is to illustrate limb preservation in a high-risk patient with compromised vascular supply who underwent a partial calcanectomy for treatment of calcaneal osteomyelitis. The patient underwent surgical resection of the calcaneus without complications and healed unremarkably with the ability to ambulate while wearing an ankle foot orthosis with a custom shoe. This report was authorized for publication as an educational report to contribute to generalizable knowledge and does not include any patient health information. PMID:27423990

  4. Waist circumference threshold values for type 2 diabetes risk.

    2009-07-01

    Adult gains in body weight, excess adiposity, and intra-abdominal fat have each been associated with risk for type 2 diabetes mellitus (T2DM), forming the basis for preventive medicine guidelines and actuarial predictions using practical indices of weight (e.g., body mass index [BMI]) and waist circumference (WC). As obesity-related disease spreads beyond affluent western countries, application of WC thresholds to other populations has highlighted issues of their generalizability. For example, U.S. national health goals based on BMI < 25 kg/m(2) and WC < 89 cm (women) and <102 cm (men) differ considerably with a recent law in Japan mandating intervention for older adults with WC exceeding 90 cm (women) and 85 cm (men). The U.S. military has also faced issues of generalizability of WC-based adiposity standards that are fair and achievable. Data from many studies indicate that WC is a reliable biomarker for T2DM risk, suggesting that, for adult men and women, action thresholds should be more stringent than current U.S. guidelines, and it would not be harmful to set worldwide targets somewhere below 90 cm for men and women, regardless of weight status. Medical technology has provided many great insights into disease, including modern imaging technologies that have differentiated fat depots that have the greatest influence on T2DM, but ultimately, an inexpensive measuring tape provides the most useful and cost-effective preventive measure for T2DM today. At some point in the future, a Star Trek-like abdominal body fat "tricorder" noninvasive assessment of tissue composition may provide an advantage over abdominal girth.

    Accumulating evidence suggests that negative perceptions towards diabetes can limit the management and prevention of the disease. The negative perceptions towards diabetes are prevalent in many different settings, especially among rural communities. Few qualitative studies have been performed to understand how the community views diabetes and its associated risk factors. This study aimed to explore general community perceptions of diabetes and its risk factors in rural Indonesia. A total of 68 participants were recruited to 12 focus group discussions (FGDs) comprised of different age groups and sexes. The FGDs were conducted in six villages in rural Purworejo District, Central Java, Indonesia, from 2011 to 2012. All FGDs were recorded and transcribed. Qualitative content analysis was performed to describe and analyse how the rural community perceived diabetes and its risk factors. Diabetes was perceived as a visible and scary sugar disease, and the affected individuals themselves were blamed for getting the disease. Recognised as 'sugar' or 'sweet-pee' disease with terrifying effects, diabetes was believed to be a disease with no cure. The participants seemed to have an unrealistic optimism with regards to the diabetes risk factors. They believed that diabetes would not affect them, only others, and that having family members with diabetes was necessary for one to develop diabetes. Our findings demonstrate that rural communities have negative perceptions about diabetes and at the same time individuals have unrealistic optimism about their own risk factors. Understanding how such communities perceive diabetes and its risk factors is important for planning prevention strategies. Health messages need to be tailored to health-related behaviours and the local culture's concepts of diseases and risk factors.

    Context/Rationale: Meta-analyses of genome-wide association studies have identified many single-nucleotide polymorphisms associated with various metabolic and cardiovascular traits, offering us the opportunity to learn about and capitalize on the links between cardiometabolic traits and type 2 diabetes (T2D). Design: In multiple datasets comprising over 30 000 individuals and 3 ethnic/racial groups, we calculated 17 genetic risk scores (GRSs) for glycemic, anthropometric, lipid, hemodynamic, and other traits, based on the results of recent trait-specific meta-analyses of genome-wide association studies, and examined associations with T2D risk. Using a training-testing procedure, we evaluated whether additional GRSs could contribute to risk prediction. Results: In European Americans, we find that GRSs for T2D, fasting glucose, fasting insulin, and body mass index are associated with T2D risk. In African Americans, GRSs for T2D, fasting insulin, and waist-to-hip ratio are associated with T2D. In Hispanic Americans, GRSs for T2D and body mass index are associated with T2D. We observed a trend among European Americans suggesting that genetic risk for hyperlipidemia is inversely associated with T2D risk. The use of additional GRSs resulted in only small changes in prediction accuracy in multiple independent validation datasets. Conclusions: The analysis of multiple GRSs can shed light on T2D etiology and how it varies across ethnic/racial groups. Our findings using multiple GRSs are consistent with what is known about the differences in T2D pathogenesis across racial/ethnic groups. However, further work is needed to understand the putative inverse correlation of genetic risk for hyperlipidemia and T2D risk and to develop ethnic-specific GRSs. PMID:24905067

In a pooled analysis comprising 9,533 cases and 11,389 controls, SNPs in WFS1 were strongly associated with diabetes risk. Rare mutations in WFS1 cause Wolfram syndrome; using a gene-centric approach, we show that variation in WFS1 also predisposes to common type 2 diabetes. PMID:17603484

    Background A growing body of evidence supports the role of type 2 diabetes as an individual-level risk factor for tuberculosis (TB), though evidence from developing countries with the highest TB burdens is lacking. In developing countries, TB is most common among the poor, in whom diabetes may be less common. We assessed the relationship between individual-level risk, social determinants and population health in these settings. Methods We performed individual-level analyses using the World Health Survey (n = 124 607; 46 countries). We estimated the relationship between TB and diabetes, adjusting for gender, age, body mass index, education, housing quality, crowding and health insurance. We also performed a longitudinal country-level analysis using data on per-capita gross domestic product and TB prevalence and incidence and diabetes prevalence for 1990–95 and 2003–04 (163 countries) to estimate the relationship between increasing diabetes prevalence and TB, identifying countries at risk for disease interactions. Results In lower income countries, individuals with diabetes are more likely than non-diabetics to have TB [univariable odds ratio (OR): 2.39; 95% confidence interval (CI): 1.84–3.10; multivariable OR: 1.81; 95% CI: 1.37–2.39]. Increases in TB prevalence and incidence over time were more likely to occur when diabetes prevalence also increased (OR: 4.7; 95% CI: 1.0–22.5; OR: 8.6; 95% CI: 1.9–40.4). Large populations, prevalent TB and projected increases in diabetes make countries like India, Peru and the Russia Federation areas of particular concern. Conclusions Given the association between diabetes and TB and projected increases in diabetes worldwide, multi-disease health policies should be considered. PMID:21252210

    Aims To describe change in self-reported diet and plasma vitamin C, and to examine associations between change in diet and cardiovascular disease risk factors and modelled 10-year cardiovascular disease risk in the year following diagnosis of Type 2 diabetes. Methods Eight hundred and sixty-seven individuals with screen-detected diabetes underwent assessment of self-reported diet, plasma vitamin C, cardiovascular disease risk factors and modelled cardiovascular disease risk at baseline and 1 year (n = 736) in the ADDITION-Cambridge trial. Multivariable linear regression was used to quantify the association between change in diet and cardiovascular disease risk at 1 year, adjusting for change in physical activity and cardio-protective medication. Results Participants reported significant reductions in energy, fat and sodium intake, and increases in fruit, vegetable and fibre intake over 1 year. The reduction in energy was equivalent to an average-sized chocolate bar; the increase in fruit was equal to one plum per day. There was a small increase in plasma vitamin C levels. Increases in fruit intake and plasma vitamin C were associated with small reductions in anthropometric and metabolic risk factors. Increased vegetable intake was associated with an increase in BMI and waist circumference. Reductions in fat, energy and sodium intake were associated with reduction in HbA1c, waist circumference and total cholesterol/modelled cardiovascular disease risk, respectively. Conclusions Improvements in dietary behaviour in this screen-detected population were associated with small reductions in cardiovascular disease risk, independently of change in cardio-protective medication and physical activity. Dietary change may have a role to play in the reduction of cardiovascular disease risk following diagnosis of diabetes. PMID:24102972

    2015-09-01

    Patients with type II diabetes (T2DM) have an elevated risk for cardiovascular disease (CVD), and it is considered to be a leading cause of morbidity and premature mortality in these patients. Many traditional risk factors such as age, male sex, hypertension, dyslipidemia, glycemic control, diabetes duration, renal dysfunction, obesity, and smoking have been studied and identified as independent factors for CVD. Quantifying the risk of CVD among diabetics using the common risk factors in order to plan the treatment and preventive measures is important in the management of these patients as recommended by many clinical guidelines. Therefore, several risk assessment tools have been developed in different parts of the world for this purpose. These include the tools that have been developed for general populations and considered T2DM as a risk factor, and the tools that have been developed for T2DM populations specifically. However, due to the differences in sociodemographic factors and lifestyle patterns, as well as the differences in the distribution of various CVD risk factors in different diabetic populations, the external applicability of these tools on different populations is questionable. This review aims to address the applicability of the existing CVD risk models to the Omani diabetic population.

    Type 2 diabetes represents a major health problem worldwide, with immigrants strongly contributing to the increase in diabetes in many countries. Norway is not immune to the process, and immigrants in the country are experiencing an increase in the prevalence of diabetes after arrival. However, the dynamics of these transitions in relation to the duration of residence in the new environment in Norway are not clearly understood. From this background, a cross-sectional quantitative study using a respondent-driven sampling method was conducted among 302 Somali women living in Oslo area. The results show that 41% of the study participants will be at risk for developing diabetes in the coming 10 years, which coincides with 85% of the study participants being abdominally obese. Significant associations were found between years of stay in Norway and the risk for diabetes with those who lived in Norway >10 years, having twofold higher odds of being at risk for developing diabetes compared to those who lived in Norway ≤5 years (OR: 2.16, CI: 1.08–4.32). Understanding the mechanisms through which exposure to the Norwegian environment leads to higher obesity and diabetes risk may aid in prevention efforts for the rapidly growing African immigrant population.

    Epidemiological evidence suggests that passive smoke exposure is related to the development of diabetes. However, data on this issue are controversial. We conducted a meta-analysis to provide a quantitative assessment of the association between passive smoking and the risk of diabetes. We searched the Medline and Embase databases up to October 2013 to identify prospective cohort studies related to passive smoke exposure and incident diabetes. Summary effect estimates with 95 % confidence intervals (CI) were derived using a fixed or random effects model, depending on the heterogeneity of the included studies. Six prospective studies that span three continents involving 154,406 participants (ages 18-74) with 7,116 new diabetes cases were included in the meta-analysis. On the basis of the Newcastle Ottawa Scale system, five studies were identified as relatively high-quality. In our primary analysis, compared to never smokers without passive smoke exposure, never smokers reporting passive smoke exposure was associated with increased risk of diabetes (pooled relative risk 1.21, 95 % CI 1.07-1.38). Such association persisted in the dose-response analysis. No indications of significant heterogeneity and publication bias were detected. Estimates of total effects were generally consistent in the sensitivity and subgroup analyses. Findings of the present meta-analysis suggest that passive smoke exposure is independently associated with the risk of diabetes. The conclusion may have a far-reaching significance for public health in countries of high smoking intensity and high incident diabetes.

    Increased cardiovascular morbidity and mortality in patients with type 2 diabetes is well established; diabetes is associated with at least a 2-fold increased risk of coronary heart disease. Approximately two-thirds of deaths among persons with diabetes are related to cardiovascular disease. Previously, diabetes was regarded as a "coronary risk equivalent," implying a high 10-year cardiovascular risk for every diabetes patient. Following the original study by Haffner et al., multiple studies from different cohorts provided varying conclusions on the validity of the concept of coronary risk equivalency in patients with diabetes. New guidelines have started to acknowledge the heterogeneity in risk and include different treatment recommendations for diabetic patients without other risk factors who are considered to be at lower risk. Furthermore, guidelines have suggested that further risk stratification in patients with diabetes is warranted before universal treatment. The Imaging Council of the American College of Cardiology systematically reviewed all modalities commonly used for risk stratification in persons with diabetes mellitus and summarized the data and recommendations. This document reviews the evidence regarding the use of noninvasive testing to stratify asymptomatic patients with diabetes with regard to coronary heart disease risk and develops an algorithm for screening based on available data.

    Type 2 Diabetes (T2D) is a chronic disease arising from the development of insulin absence or resistance within the body, and a complex interplay of environmental and genetic factors. The incidence of T2D has increased throughout the last few decades, together with the occurrence of the obesity epidemic. The consideration of variants identified by Genome Wide Association Studies (GWAS) into risk assessment models for T2D could aid in the identification of at-risk patients who could benefit from preventive medicine. In this study, we build several risk assessment models, evaluated with two different classification approaches (Logistic Regression and Neural Networks), to measure the effect of including genetic information in the prediction of T2D. We used data from to the Original and the Offspring cohorts of the Framingham Heart Study, which provides phenotypic and genetic information for 5245 subjects (4306 controls and 939 cases). Models were built by using several covariates: gender, exposure time, cohort, body mass index (BMI), and 65 SNPs associated to T2D. We fitted Logistic Regressions and Bayesian Regularized Neural Networks and then assessed their predictive ability by using a ten-fold cross validation. We found that the inclusion of genetic information into the risk assessment models increased the predictive ability by 2%, when compared to the baseline model. Furthermore, the models that included BMI at the onset of diabetes as a possible effector, gave an improvement of 6% in the area under the curve derived from the ROC analysis. The highest AUC achieved (0.75) belonged to the model that included BMI, and a genetic score based on the 65 established T2D-associated SNPs. Finally, the inclusion of SNPs and BMI raised predictive ability in all models as expected; however, results from the AUC in Neural Networks and Logistic Regression did not differ significantly in their prediction accuracy.

    This paper presents 10 recommendations for improving the European Medicines Agency's guidance for environmental risk assessment of human pharmaceutical products. The recommendations are based on up-to-date, available science in combination with experiences from other chemical frameworks such as the REACH-legislation for industrial chemicals. The recommendations concern: expanding the scope of the current guideline; requirements to assess the risk for development of antibiotic resistance; jointly performed assessments; refinement of the test proposal; mixture toxicity assessments on active pharmaceutical ingredients with similar modes of action; use of all available ecotoxicity studies; mandatory reviews; increased transparency; inclusion of emission data from production; and a risk management option. We believe that implementation of our recommendations would strengthen the protection of the environment and be beneficial to society. Legislation and guidance documents need to be updated at regular intervals in order to incorporate new knowledge from the scientific community. This is particularly important for regulatory documents concerning pharmaceuticals in the environment since this is a research field that has been growing substantially in the last decades.

    Several investigators have observed an association between alcohol consumption and elevated glucose levels, raising the possibility that alcohol may increase the risk of diabetes. This hypothesis was evaluated prospectively among 85,051 women participating in the Nurses' Health Study who were 34 to 59 years of age in 1980 and had no history of cancer, coronary heart disease, or diabetes. At baseline, participants completed an independently validated dietary questionnaire which included information on the consumption of beer, wine, and liquor. Incident cases of non-insulin-dependent diabetes were reported on follow-up questionnaires sent in 1982 and 1984 (98% response to at least one follow-up); 526 cases were confirmed by a supplementary questionnaire regarding symptoms, laboratory values, and treatment. The risk of diabetes decreased monotonically with increasing alcohol consumption (chi trend = -9.4, p less than 0.0001). Compared with nondrinkers, women consuming 5-14.9 g of alcohol per day (about 4-10 drinks per week) had an age-adjusted relative risk of diabetes of 0.4 (95% confidence interval (CI) 0.3-0.6); for 15 g or more per day, the relative risk was 0.3 (95% CI 0.2-0.4). However, a strong inverse association between alcohol drinking and body weight explained much of the apparent protective effect of alcohol. After simultaneous adjustment for Quetelet index (weight (kg)/height (m)2), family history of diabetes, total caloric intake, and age, the relative risk of diabetes for consumers of 5-14.9 g per day was 0.8 (95% CI 0.6-1.2), and for women who drank 15+ g per day, the relative risk was 0.6 (95% CI 0.3-0.9). These data provide no support for the hypothesis that moderate alcohol intake increases the risk of non-insulin-dependent diabetes. PMID:3414660

    INTRODUCTION This study aimed to determine the risk factors of diabetic Charcot arthropathy of the foot among diabetic patients with and without foot problems. METHODS This was a case-control study involving diabetic patients attending the Diabetic Foot Care and Wound Management Clinic at University Malaya Medical Centre, Kuala Lumpur, Malaysia, from June 2010 to June 2011. Data on sociodemographic profiles, foot factors and diabetes characteristics was collected and analysed. RESULTS A total of 48 diabetic patients with Charcot arthropathy of the foot were identified. Data from these 48 patients was compared with those of 52 diabetic patients without foot problems. Up to 83.3% of patients with diabetic Charcot arthropathy presented with unilateral Charcot foot, most commonly located at the midfoot (45.8%). Patients with a history of foot problems, including foot ulcer, amputation, surgery or a combination of problems, had the highest (26-time) likelihood of developing Charcot arthropathy (odds ratio 26.4; 95% confidence interval 6.4–109.6). Other significant risk factors included age below 60 years, more than ten years’ duration of diabetes mellitus and the presence of nephropathy. CONCLUSION A history of prior diabetic foot problems is the greatest risk factor for developing diabetic Charcot arthropathy, compared with other risk factors such as diabetes characteristics and sociodemographic profiles. Preventive management of diabetic foot problems in the primary care setting and multidisciplinary care are of paramount importance, especially among chronic diabetic patients. PMID:27075668

    Objective Leptin alleviates hyperglycemia in rodent models of Type 1 diabetes by activating leptin receptors within the central nervous system. Here we delineate whether non-canonical leptin signaling through the Creb-regulated transcriptional coactivator 1 (Crtc1) contributes to leptin-dependent improvements in diabetic glucose metabolism. Methods We employed mice with a targeted genetic disruption of Crtc1, tracer dilution techniques and neuroanatomical studies to interrogate whether Crtc1 enables leptin to improve glucose metabolism in streptozotocin-induced (STZ) diabetes. Results Here we show that leptin improves diabetic glucose metabolism through Crtc1-dependent and independent mechanisms. We find that leptin reduces diabetic hyperglycemia, hepatic gluconeogenic gene expression and selectively increases glucose disposal to brown adipose tissue and heart, in STZ-diabetic Crtc1WT mice but not Crtc1+/− mice. By contrast, leptin decreases circulating glucagon levels in both STZ-diabetic Crtc1WT and Crtc1+/− mice. We also demonstrate that leptin promotes Crtc1 nuclear translocation in pro-opiomelanocortin (Pomc) and non-Pomc neurons within the hypothalamic arcuate nucleus (ARC). Accordingly, leptin's ability to induce Pomc gene expression in the ARC is blunted in STZ-diabetic Crtc1+/− mice. Conclusions Our study reveals that Crtc1 functions as a conduit for leptin's glucoregulatory actions in insulin-dependent diabetes. This study also highlights a new role for Crtc1 in modulating peripheral glucose metabolism. PMID:25737949

    Type 2 diabetes mellitus is reaching epidemic proportions among children and adolescents. School health fairs offer an opportunity to identify children with risk factors for the development of type 2 diabetes mellitus. This study identified selected risk factors (i.e., high-risk racial/ethnic group, obesity, elevated blood pressure, elevated casual blood glucose, elevated total cholesterol, and the presence of acanthosis nigricans) for development of type 2 diabetes mellitus in rural children with or without a family history of diabetes during annual school health fairs. Of the children screened, 40% (673) presented with two or more of the identified risk factors for type 2 diabetes mellitus. The presence of multiple risk factors in participants reporting a positive family history of diabetes mellitus versus those with no family history was not statistically significant. Based on the study results, factors other than family history may be more predictive for the development of type 2 diabetes mellitus in rural school children.

    Objective Little is known about the development of the quality of diabetes care in Germany. The aim of this study is to analyze time trends in patient self-management, physician-delivered care, medication, risk factor control, complications and quality of life from 2000 to 2014. Methods Analyses are based on data from individuals with type 2 diabetes of the population-based KORA S4 (1999–2001, n = 150), F4 (2006–2008, n = 203), FF4 (2013/14, n = 212) cohort study. Information on patient self-management, physician-delivered care, medication, risk factor control and quality of life were assessed in standardized questionnaires and examinations. The 10-year coronary heart disease (CHD) risk was calculated using the UKPDS risk engine. Time trends were analyzed using multivariable linear and logistic regression models adjusted for age, sex, education, diabetes duration, and history of cardiovascular disease. Results From 2000 to 2014 the proportion of participants with type 2 diabetes receiving oral antidiabetic/cardio-protective medication and of those reaching treatment goals for glycemic control (HbA1c<7%, 60% to 71%, p = 0.09), blood pressure (<140/80 mmHg, 25% to 69%, p<0.001) and LDL cholesterol (<2.6 mmol/l, 13% to 27%, p<0.001) increased significantly. However, improvements were generally smaller from 2007 to 2014 than from 2000 to 2007. Modeled 10-year CHD risk decreased from 30% in 2000 to 24% in 2007 to 19% in 2014 (p<0.01). From 2007 to 2014, the prevalence of microvascular complications decreased and quality of life increased, but no improvements were observed for the majority of indicators of self-management. Conclusion Despite improvements, medication and risk factor control has remained suboptimal. The flattening of improvements and deteriorations in quality of (self-) care since 2007 indicate that more effort is needed to improve quality of care and patient self-management. Due to selection or lead time bias an overestimation of quality of care

    Knowledge of patients' risk perceptions is essential for the management of chronic diseases. This study aimed to assess the reliability and validity of a Persian (Farsi) language translation of the Risk Perception Survey-Diabetes Mellitus. After forward-backward translation the RPS-DM was randomly administered to 106 adult patients with diabetes who were enrolled in a teaching referral clinic in the north of the Islamic Republic of Iran (Rasht). Internal consistency and exploratory factor analysis were applied. The minimum value for internal consistency was 0.50 for risk knowledge and the highest value was 0.88 on the optimistic bias subscale. Principal component analysis showed that the items of the composite risk score matched with the same items in the English language version, except for question numbers 16, 24 and 25. The Persian version of RPS-DM is the first standardized tool for measuring risk perception and knowledge about diabetes complications in the Islamic Republic of Iran.

    In this study we aimed to investigate the risk factors associated with arterial hypertension and diabetes mellitus in young adults assisted in six Family Health Units (UBASF), of Fortaleza, Ceará, Brazil. This is a descriptive and documental study, based on the records of the Care Program to Arterial Hypertension and Diabetes Mellitus (HIPERDIA). The sample was composed of 60 records, including hypertensive, diabetics and patients with the two diagnoses. The results showed prevalence of young female adults (78%). Regarding the risk factors, arterial hypertension (n=45), family history (n=33), overweight (n=33) and sedentary lifestyle (n=27) stood out. Regarding the cardiovascular risk stratification, most presented Medium additional risk for cardiovascular disease. We concluded that the individualized evaluation of risk factors supports an action addressed for possible events, being necessary investments in prevention and also in training and maintenance of the HIPERDIA system.

    Type 1 diabetes affects around 370,000 adults in the UK, about 10% of all those diagnosed with diabetes. In type 1 diabetes there is a lack of beta cell insulin secretion as a result of autoimmune destruction of the beta cells. However, patients are not affected by insulin resistance, and so do not routinely experience the features of metabolic syndrome that occur in type 2 diabetes. NICE recommends considering further investigation with autoantibody testing or measurement of C-peptide when: type 1 diabetes is suspected but the presentation includes atypical features (e.g. age ≥50, BMI ≥ 25 kg/m2, slow evolution of hyperglycaemia or long prodrome); type 1 diabetes has been diagnosed and treatment started but there is a clinical suspicion that the patient may have a monogenic form of diabetes, and C-peptide and/or autoantibody testing may guide the use of genetic testing; classification is uncertain, and confirming type 1 diabetes would have implications for therapy. Structured education is the cornerstone of care providing tools to allow effective self-management. Following a new diagnosis of type 1 diabetes structured education should be offered within 12 months. Newly diagnosed patients should be offered a regimen including a basal (long-acting) insulin with bolus (rapid-acting) insulin given at mealtimes. The optimal regimen, which should be offered from diagnosis, is a combination of twice daily insulin detemir and a rapid-acting analogue given at mealtimes. However, where glycaemic control is already optimised on an alternative insulin regimen this should not be discontinued. PMID:27180499

    Objective In this pilot study, we evaluated the impact of providing patients with a literacy-appropriate diabetes education guide accompanied by brief counseling designed for use in primary care. Methods We provided the Living with Diabetes guide and brief behavior change counseling to 250 English and Spanish speaking patients with type 2 diabetes. Counseling sessions using collaborative goal setting occurred at baseline and by telephone at 2 and 4 weeks. We measured patients' activation, self-efficacy, diabetes distress, knowledge, and self-care at baseline and 3-month follow-up. Results Statistically significant (p ≤ 0.001) and clinically important (effect sizes = 0.29–0.42) improvements were observed in participants' activation, self-efficacy, diabetes-related distress, self-reported behaviors, and knowledge. Improvements were similar across literacy levels. Spanish speakers experienced both greater improvement in diabetes-related distress and less improvement in self-efficacy levels than English speakers. Conclusion A diabetes self-management support package combining literacy-appropriate patient education materials with brief counseling suitable for use in primary care resulted in important shortterm health-related psychological and behavioral changes across literacy levels. Practice implications Coupling literacy-appropriate education materials with brief counseling in primary care settings may be an effective and efficient strategy for imparting skills necessary for diabetes self-management.

    Importance Although depression and type 2 diabetes may independently increase dementia risk, no studies have examined whether the risk of dementia among people with both is higher than the sum of each individually. Objective To examine risk of all-cause dementia among persons with depression, diabetes or both compared to those with neither. Design A population-based cohort study of 2,454,532 adults, including 477,133 (19.4%) with depression, 223,174 (9.1%) with diabetes and 95,691 (3.9%) with both. Setting Denmark Participants All dementia-free Danish citizens ≥50 years old between January 1, 2007 through 2013. Main outcome measure Dementia was ascertained by physician diagnosis from the Danish National Patient Register, the Danish Psychiatric Central Register (DPCR), and/or prescription of a cholinesterase inhibitor or memantine from the Danish National Prescription Registry (DNPR). Depression was ascertained by psychiatrist diagnosis from the DPCR or antidepressant prescription from the DNPR. Diabetes was identified using the Danish National Diabetes Register. The risk of all-cause dementia associated with diabetes, depression or both was estimated using Cox proportional hazards regression models that adjusted for potential confounding factors such as demographics and potential intermediates such as medical comorbidity. Results During 13,834,645 million person-years of follow-up, 59,663 (2.4%) developed dementia of whom 6,466 (10.8%) had diabetes, 15,729 (26.4%) had depression and 4,022 (6.7%) had both. The adjusted hazard ratio of developing all-cause dementia was 1.83 (95% confidence interval: 1.80, 1.87) for persons with depression, 1.20 (95% CI: 1.17, 1.23) for persons with diabetes, and 2.17 (95% CI: 2.10, 2.24) for those with both as compared to those with neither. The excess risk of all-cause dementia observed for individuals with comorbid depression and diabetes surpassed the summed risk associated with the two individually, especially for younger

    Background While gastric noncardia adenocarcinoma (GNCA) incidence rates in the US have decreased, the rates of gastric cardia adenocarcinoma (GCA) and esophageal adenocarcinoma (EADC) have increased. Obesity increases the risks of GCA and EADC, and the associations may be partially mediated by insulin resistance. A few case-control studies have shown an association between diabetes and an increased risk of EADC. Methods We prospectively examined the association between diabetes and upper gastrointestinal (UGI) cancers in a cohort of 469,448 people in the US, ages 50-71 at baseline. Cox proportional hazards regression was used to estimate the hazard ratios (HR) and 95% confidence intervals (CI) for diabetes and UGI cancers, controlling for multiple potential confounders, including body mass index (BMI). Results We observed no association of self-reported diabetes with risk of EADC, HR (95%CI) = 0.98 (0.73-1.31), esophageal squamous cell carcinoma (ESCC), HR (95%CI) = 1.02 (0.60-1.74), or GNCA, HR (95%CI) = 0.98 (0.70-1.37). However, diabetes was significantly associated with an increased risk of GCA, HR (95%CI) = 1.89 (1.43-2.50). The significant association between diabetes and risk of GCA remained after adjustment for BMI, HR (95%CI) = 1.70 (1.28-2.26) and did not differ by BMI strata (pinteraction =0.83). The significant association was unchanged when restricting to only overweight subjects (BMI 25 - ≤30), HR (95%CI) = 1.83 (1.18-2.85). Conclusions We found a significant association between self-reported diabetes and increased risk of GCA. Impact Our results suggest that the metabolic and hormonal changes related to diabetes may play a role in the etiology of GCA independently from BMI. PMID:21415356

    African Americans have a high risk for type 2 diabetes. Genetic traits, the prevalence of obesity, and insulin resistance all contribute to the risk of diabetes in the African American community. African Americans have a high rate of diabetic complications, because of poor glycaemic control and racial disparities in health care in the USA. African Americans with diabetes may have an atypical presentation that simulates type 1 diabetes, but then their subsequent clinical course is typical of type 2 diabetes. Culturally sensitive strategies, structured disease management protocols, and the assistance of nurses, diabetic educators, and other health care professionals are effective in improving the outcome of diabetes in the African American community.

    Carbon tetrachloride has been used extensively within the DOE nuclear weapons facilities. Rocky Flats was formerly the largest volume consumer of CCl4 in the United States using 5000 gallons in 1977 alone (Ripple, 1992). At the Hanford site, several hundred thousand gallons of CCl4 were discharged between 1955 and 1973 into underground cribs for storage. Levels of CCl4 in groundwater at highly contaminated sites at the Hanford facility have exceeded 8 the drinking water standard of 5 ppb by several orders of magnitude (Illman, 1993). High levels of CCl4 at these facilities represent a potential health hazard for workers conducting cleanup operations and for surrounding communities. The level of CCl4 cleanup required at these sites and associated costs are driven by current human health risk estimates, which assume that CCl4 is a genotoxic carcinogen. The overall purpose of these studies was to improve the scientific basis for assessing the health risk associated with human exposure to CCl4. Specific research objectives of this project were to: (1) compare the rates of CCl4 metabolism by rats, mice and hamsters in vivo and extrapolate those rates to man based on parallel studies on the metabolism of CCl4 by rat, mouse, hamster and human hepatic microsomes in vitro; (2) using hepatic microsome preparations, determine the role of specific cytochrome P450 isoforms in CCl4-mediated toxicity and the effects of repeated inhalation and ingestion of CCl4 on these isoforms; and (3) evaluate the toxicokinetics of inhaled CCl4 in rats, mice and hamsters. This information has been used to improve the physiologically based pharmacokinetic (PBPK) model for CCl4 originally developed by Paustenbach et al. (1988) and more recently revised by Thrall and Kenny (1996). Another major objective of the project was to provide scientific evidence that CCl4, like chloroform, is a hepatocarcinogen only when exposure results in cell damage, cell killing and regenerative proliferation.

    Alzheimer disease and type 2 diabetes are characterized by increased prevalence with aging, a genetic predisposition, and comparable pathological features in the islet and brain (amyloid derived from amyloid beta protein in the brain in Alzheimer disease and islet amyloid derived from islet amyloid polypeptide in the pancreas in type 2 diabetes). Evidence is growing to link precursors of amyloid deposition in the brain and pancreas with the pathogenesis of Alzheimer disease and type 2 diabetes, respectively. Given these similarities, we questioned whether there may be a common underlying mechanism predisposing to islet and cerebral amyloid. To address this, we first examined the prevalence of type 2 diabetes in a community-based controlled study, the Mayo Clinic Alzheimer Disease Patient Registry (ADPR), which follows patients with Alzheimer disease versus control subjects without Alzheimer disease. In addition to this clinical study, we performed a pathological study of autopsy cases from this same community to determine whether there is an increased prevalence of islet amyloid in patients with Alzheimer disease and increased prevalence of cerebral amyloid in patients with type 2 diabetes. Patients who were enrolled in the ADPR (Alzheimer disease n = 100, non-Alzheimer disease control subjects n = 138) were classified according to fasting glucose concentration (FPG) as nondiabetic (FPG <110 mg/dl), impaired fasting glucose (IFG, FPG 110-125 mg/dl), and type 2 diabetes (FPG >126 mg/dl). The mean slope of FPG over 10 years in each case was also compared between Alzheimer disease and non-Alzheimer disease control subjects. Pancreas and brain were examined from autopsy specimens obtained from 105 humans (first, 28 cases of Alzheimer disease disease vs. 21 non-Alzheimer disease control subjects and, second, 35 subjects with type 2 diabetes vs. 21 non-type 2 diabetes control subjects) for the presence of islet and brain amyloid.

    Abstract Objective Hemoglobin A1c (A1C) has recently been recommended for diagnosing diabetes mellitus and diabetes risk (prediabetes). Its performance compared with fasting plasma glucose (FPG) and 2-h post-glucose load (2HPG) is not well delineated. We compared the performance of A1C with that of FPG and 2HPG in preoperative cardiac surgery patients. Methods Data from 92 patients without a history of diabetes were analyzed. Patients were classified with diabetes or prediabetes using established cutoffs for FPG, 2HPG, and A1C. Sensitivity and specificity of the new A1C criteria were evaluated. Results All patients diagnosed with diabetes by A1C also had impaired fasting glucose, impaired glucose tolerance, or diabetes by other criteria. Using FPG as the reference, sensitivity and specificity of A1C for diagnosing diabetes were 50% and 96%, and using 2HPG as the reference they were 25% and 95%. Sensitivity and specificity for identifying prediabetes with FPG as the reference were 51% and 51%, respectively, and with 2HPG were 53% and 51%, respectively. One-third each of patients with prediabetes was identified using FPG, A1C, or both. When testing A1C and FPG concurrently, the sensitivity of diagnosing dysglycemia increased to 93% stipulating one or both tests are abnormal; specificity increased to 100% if both tests were required to be abnormal. Conclusions In patients before cardiac surgery, A1C criteria identified the largest number of patients with diabetes and prediabetes. For diagnosing prediabetes, A1C and FPG were discordant and characterized different groups of patients, therefore altering the distribution of diabetes risk. Simultaneous measurement of FGP and A1C may be a more sensitive and specific tool for identifying high-risk individuals with diabetes and prediabetes. PMID:21854260

    Background and aims Co-existing major depression was found to have a negative impact on the diabetes outcome and the quality of life. The aim of the present study was to assess the prevalence of depressive symptoms in Romanian diabetes patients and to identify the risk factors associated with depression. Methods A total of 144 type 2 diabetes patients were included in the study. Five models of presumed predictors were used to assess the risk factors for depressive symptoms, using hierarchical regression analysis. Together with demographics, disease, lifestyle predictors, previous depressive symptoms and diabetes distress were taken into account. Results In our sample the prevalence of depression was 12.6%. Main risk factors for depressive symptoms were previous depressive symptoms which were associated with depression in both Model 4 (β=0.297, p=0.013) and Model 5 (β=0.239, p=0.017) and diabetes distress in Model 5 (β=0.540, p≤0.001). Employment (β =−0.276, p=0.029) and increased number of diabetes complications (β=0.236, p=0.017) became significant when diabetes distress was added to the analysis. Conclusions The overall prevalence of depressive symptoms was found to be in range with the prevalence identified in the literature. Previous depression and diabetes distress were both independently associated with depression, confirming the bidirectional relationship between depression and diabetes distress. Due to the consequences for daily living, screening for diabetes distress and depression should be done in primary care units both by physicians and trained nurses. PMID:27547056

    Background: Retinol binding protein-4 (BP-4) a new adipocytokine, specifically binds to retinol, through experimental studies, reported its link between obesity and insulin resistance (IR). But till date no studies are available on influence of genetic predisposition of diabetes on RBP-4 expression. Hence, we aimed to study the influence of genetic predisposition of diabetes on the serum RBP-4 and its role in development of IR and diabetes in genetically high risk population. Materials and Methods: Healthy non diabetic individuals (age 18 to 22) were grouped into Group I: Control (n = 81), whose parents are non diabetic, non hypertensive and does not have any family history of coronary heart diseases. Group II: (n = 157) with one of their parents diabetic and Group III: (n = 47) with both parents diabetic. In all the participants, we estimated fasting serum RBP-4, insulin and glucose. Homeostasis model for assessment-insulin resistance (HOMA-IR) and homeostasis model for assessment-beta cell dysfunction (HOMA-B) were calculated from fasting serum insulin and glucose levels. Results: In this study, we observed significantly higher RBP-4 levels 12.71 ± 2.3 in Group-II and 13.25 ± 2 in Group-III, respectively when compared to Group-I 11.4 ± 1.8 (P < 0.01). RBP-4 showed a significantly strong positive correlation with plasma insulin, glucose and HOMA-IR in genetically high risk population (group II and III) P < 0.01. Linear regression analysis revealed a strong positive association of RBP-4 with parental diabetes even after adjusting for BMI, age and sex (OR 1.53, 95% CI 1.089-1.40). Conclusion: Higher serum RBP-4 and its positive correlation with Insulin, glucose, and HOMA-IR in healthy non diabetic participants of genetically high risk population, indicating its role as predictor for the onset of diabetes in coming future.

    Objective To better understand the association between a modified Mediterranean diet pattern in young adulthood, cardiorespiratory fitness in young adulthood, and the odds of developing pre-diabetes or diabetes by middle age. Research design and methods Participants from the Coronary Artery Risk Development in Young Adults (CARDIA) study who did not have pre-diabetes or diabetes at baseline (year 0 (Y0), ages 18–30) and who had data available at the Y0 and year 25 (Y25) visits were included in this analysis (n=3358). Polytomous logistic regression models were used to assess the association between baseline dietary intake and fitness data and odds of pre-diabetes or diabetes by middle age (Y25, ages 43–55). Results At the Y25 visit, 1319 participants (39%) had pre-diabetes and 393 (12%) had diabetes. Higher baseline fitness was associated with lower odds of pre-diabetes and of diabetes at Y25. After adjustment for covariates, each SD increment in treadmill duration (181 s) was associated with lower odds for pre-diabetes (OR 0.85, 95% CI 0.75 to 0.95, p=0.005) and for diabetes (OR 0.71, 95% CI 0.60 to 0.85, p=0.0002) when compared to normal glycemia. A modified Mediterranean diet pattern was not associated with either pre-diabetes or diabetes. No interaction between cardiorespiratory fitness and dietary intake was observed, but baseline fitness remained independently associated with incident pre-diabetes and diabetes following adjustment for diet. Conclusions Higher cardiorespiratory fitness in young adulthood, but not a modified Mediterranean diet pattern, is associated with lower odds of pre-diabetes and of diabetes in middle age.

    2015-01-01

    Background: Mobile health (mHealth) is an expanding field which includes the use of social media and mobile applications (apps). Apps are used in diabetes self-management but it is unclear whether these are being used to support safe drinking of alcohol by people with type 1 diabetes (T1DM). Alcohol health literacy is poor among young adults with T1DM despite specific associated risks. Methods: Systematic literature review followed by critical appraisal of commercially available apps. An eSurvey investigating access to mHealth technology, attitudes toward apps for diabetes management and their use to improve alcohol health literacy was completed by participants. Results: Of 315 articles identified in the literature search, 7 met the inclusion criteria. Ten diabetes apps were available, most of which lacked the educational features recommended by clinical guidelines. In all, 27 women and 8 men with T1DM, aged 19-31 years were surveyed. Of them, 32 had access to a smartphone/tablet; 29 used apps; 20 used/had used diabetes apps; 3 had used apps related to alcohol and diabetes; 11 had discussed apps with their health care team; 22 felt more communication with their health care team would increase awareness of alcohol-associated risks. Conclusions: Use of mobile apps is commonplace but the use of apps to support safe drinking in this population was rare. Most participants expressed a preference for direct communication with their health care teams about this subject. Further research is needed to determine the preferences of health care professionals and how they can best support young adults in safe drinking. PMID:26251369

    The prevalence of diabetes in Jordan has been increasing. The early diagnosis of diabetes is vital to slow its progression. The Arab Risk (ARABRISK) screening tool is a self-administered questionnaire used to determine people who are at high risk for developing diabetes. This study aimed to identify people at high risk for developing type 2 diabetes by using the ARABRISK in the capital of Jordan.A cross-sectional study was conducted with a convenience sample of people in the capital of Jordan. The ARABRISK screening tool was administered to identify the participants' risk for developing diabetes. In addition to descriptive statistics, percentages of the ARABRISK categories were represented, and an independent samples t test was used to explore the differences between men and women. A total of 513 participants with a mean age of 51.94 (SD = 10.33) were recruited; 64.9% of the participants were men (n = 333).The total ARABRISK score ranged from 0 to 25 with a mean score of 12.30 (SD = 4.76). Using the independent samples t test, women (mean = 13.25, SE = 0.10) had significantly higher ARABRISK total scores than men did (mean = 12.95, SE = 0.09), t(141) = -2.23, P = 0.03 in the "moderate risk" category. All of the items in the ARABRISK questionnaire were found to be good predictors of the ARABRISK total scores. Among them, age, body mass index (BMI), and high blood glucose (HBG) were the best predictors as indicated by the standardized regression coefficient (β). Older age, obesity, elevated weight circumference, absence of daily physical activity, daily consumption of fruits/vegetables, presence of high blood pressure (HBP), and HBG were significantly associated with increased odds of high ARABRISK total scores. Neither a history of gestational diabetes nor a positive family history was associated with an increased odds of high ARABRISK total scores.By identifying risk factors in these participants, interventions and lifestyle

    Falls are a major health issue for older adults, especially for those who develop type 2 diabetes who must contend with age-related declines in balance, muscle strength, and walking ability. They must also contend with health-related issues specific to the disease process. Given the general association between these variables and falls, being able to identify which measures negatively impact on balance in older diabetic persons is a critical step. Moreover, designing specific interventions to target these physiologic functions underlying balance and gait control will produce the greatest benefit for reducing falls in older persons with diabetes.

    Background South Asians have higher risk of diabetic complications compared with white Europeans. The aim of this study was to compare management of cardiovascular risk factors between Bangladeshis and white Europeans. Methods A retrospective survey of all diabetic patients attending an Inner London hospital diabetic clinic over one year was undertaken. Data were obtained from the hospital diabetes database: presence of macrovascular (myocardial infarction, angina, stroke, transient ischaemic attack, cardiac intervention) and microvascular disease (neuropathy, retinopathy, and nephropathy), glycated haemoglobin, blood pressure, lipids, smoking, and body mass index (BMI) were all determined. Results A total of 1162 white European and 912 Bangladeshi patients with full data available were included in the analyses. The groups were equivalent in age, sex, duration of diabetes. Compared with white Europeans, Bangladeshis had more macrovascular disease (19.5% v 11.9% p<0.01), sight threatening retinopathy (7.2% v 3.8%, p<0.01), and nephropathy (15.3% v 9.1%, p<0.01). In addition, Bangladeshis had significantly more male smokers (28.1% v 22.1%, p<0.01), poorer glycaemic control (mean HbA1c 8.6% v 8.1%, p = 0.039), greater proportion with uncontrolled hypercholesterolaemia (total cholesterol >5.0 mmol/l, 31.6% v 26% p = 0.05), and poorer control of blood pressure (proportion with BP >140/80 mm Hg, 43.2% v 32.1%, p<0.01). Conclusions South Asians with type 2 diabetes have poorer glycaemic, blood pressure, and lipid control than white Europeans. The reasons for this are probably multifactorial. PMID:16517804

    IGF-I shares structural homology and in vitro metabolic activity with insulin. Laboratory models suggest that IGF-I and its binding proteins IGFBP-1 and IGFBP-2 have potentially beneficial effects on diabetes risk, whereas IGFBP-3 may have adverse effects. We therefore conducted a prospective nested case-control investigation of incident diabetes (n = 742 case subjects matched 1:1 to control subjects) and its associations with IGF-axis protein levels in the Nurses' Health Study, a cohort of middle-aged women. The median time to diabetes was 9 years. Statistical analyses were adjusted for multiple risk factors, including insulin and C-reactive protein. Diabetes risk was fivefold lower among women with baseline IGFBP-2 levels in the top versus bottom quintile (odds ratio [OR](q5-q1) = 0.17 [95% CI 0.08-0.35]; P trend < 0.0001) and was also negatively associated with IGFBP-1 levels (OR(q5-q1) = 0.37 [0.18-0.73]; P trend = 0.0009). IGFBP-3 was positively associated with diabetes (OR(q5-q1) = 2.05 [1.20-3.51]; P trend = 0.002). Diabetes was not associated with total IGF-I levels, but free IGF-I and diabetes had a significant association that varied (P interaction = 0.003) by insulin levels above the median (OR(q5-q1) = 0.48 [0.26-0.90]; P trend = 0.0001) versus below the median (OR(q5-q1) = 2.52 [1.05-6.06]; P trend < 0.05). Thus, this prospective study found strong associations of incident diabetes with baseline levels of three IGFBPs and free IGF-I, consistent with hypotheses that the IGF axis might influence diabetes risk.

    OBJECTIVE To examine the prospective association between accordance with the 2005 Dietary Guidelines for Americans (DGA) and subsequent diabetes incidence and changes in cardiometabolic risk factors. RESEARCH DESIGN AND METHODS The sample consisted of 4,381 black and white young adults examined repeatedly from 1985 to 2005. We used the 2005 Diet Quality Index (DQI) to rate participants’ diets based on meeting key dietary recommendations conveyed by the 2005 DGA. RESULTS Overall, we found no association between DQI score and diabetes risk using Cox models adjusted for potential confounders. Higher DQI scores were associated with favorable changes in HDL cholesterol and blood pressure overall (P for trend <0.05), but with increased insulin resistance among blacks (P for trend <0.01). CONCLUSIONS Our findings highlight the need for evaluation of the DGA’s effectiveness, particularly among ethnic minority populations. Clinicians should be aware that following the DGA might not lower diabetes risk. PMID:21478463

    Although increased urinary albumin excretion may increase the risk of adverse renal outcomes in patients with diabetes, it remains unclear whether microalbuminuria is associated with a higher incidence of macroalbuminuria in the absence of non-diabetic kidney events that frequently develop during the long-term course of type 2 diabetes. This historical cohort study included patients with type 2 diabetes, spot urine albumin:creatinine ratio (ACR) <300 mg/gCr and normal serum creatinine concentrations treated between August 1988 and April 2015. Patients with any evidence suggesting non-diabetic kidney diseases at baseline were excluded. Over a median follow-up of 50 months, 70 of the 1760 included patients developed macroalbuminuria. Twenty-one of these patients were diagnosed with non-diabetic renal events. The five-year cumulative incidence of macroalbuminuria in patients with ACRs of 0–7.5 mg/gCr, 7.5–30 mg/gCr, 30–150 mg/gCr, and 150–300 mg/gCr were 0%, 0.53%, 3.5%, and 36.0%, respectively, with significant differences between each pair of ACR categories. In type 2 diabetes, higher urinary ACR, even within a level of normoalbuminuria, was associated with a greater incidence of macroalbuminuria when non-diabetic renal events were excluded. These results conflict with findings suggesting that microalbuminuria is a poor indicator for the progression of diabetic nephropathy. PMID:27210499

    Introduction Hypertension is a major public health problem in India and worldwide. Since hypertension is often asymptomatic, it commonly remains undetected, leading to serious complications if untreated. Hypertension is one of the leading causes of end stage renal disease. It doubles the risk of developing coronary artery disease, increases the risk of congestive heart failure by four folds and that of cerebrovascular disease and stroke by seven folds. Hypertension is directly responsible for 57% of all stroke deaths and 42% of coronary heart disease deaths in India. Aim To identify prevalence and risk factors for hypertension in a semi urban population of Mangalore, who participated in Boloor Diabetes Study (BDS-II). Materials and Methods This cross-sectional study was conducted on 551 subjects aged ≥ 20 years who were randomly selected. Hypertension was diagnosed and classified according to Joint National Committee 7 (JNC) criteria. Blood pressure was measured by a doctor using calibrated sphygmomanometer. Anthropometric measurements, lipid and glucose estimations were done for all subjects. Statistical analysis was done using Chi-square test and student’s t-test (unpaired). Multivariate logistic regression analysis was done using hypertension as dependent variable and the various risk factors as independent variables. Results Overall prevalence of hypertension in the community was 41% (227/551) (40.9% in men, 41.3% in women). Prehypertension was found in 40% (223/551) (45.4% in men, 38.1% in women), and only 18.3% (101/551) had normal blood pressure. Stage I hypertension was seen in 29.7% (164/551) (28.9% in men, 30.1% in women). Stage II hypertension was seen in 11.4% (63/551) (12% in men, 11% in women). Age, obesity, diabetes, serum cholesterol and serum triglycerides were strongly associated with hypertension. Only 46% (254/551) of the hypertensive subjects were aware that they were hypertensive. Conclusion Prevalence of hypertension was high in this

    The objective of the present study was to investigate the effect of ethanolic extract of Butea superba (Roxb.) on erectile dysfunction in diabetic rats by the measurement of intracavernous pressure (ICP) and on cavernosal smooth muscle relaxation. Male Sprague-Dawley rats were induced to become diabetic by a single intravenous injection of Streptozotocin (55 mg kg(-1) body weight). The ethanolic extract at the concentration of 1, 10 and 100 mg kg(-1) BW was administered orally once a day to diabetic rats in each group for 4 weeks. Diabetic rats showed a significant decrease in both ICP and the relaxation of the cavernosal smooth muscle compared with the normal rats. The extract of B. superba significantly increased the ICP with the effective dose of 10 mg kg(-1) BW (61.00 ± 11.11 mmHg versus 39.61 ± 11.01 mmHg in the diabetic control group). Moreover, the B. superba-treated group also showed enhanced relaxation of the cavernosal smooth muscle with EC(50) of 1.17 mg ml(-1). These results suggest that the extract of B. superba enhanced penile erection in diabetic rats by increasing the ICP. This might be explained by the increased blood flow as a result of the relaxation of the cavernous smooth muscle.

    Diabetes Mellitus type 2 (DM2) is a metabolic disease that develops by a decrease in sensitivity of insulin receptors as an effect of the disruption certain metabolic functions in the processing of glucose. DM2 patients have, uncontrolled glucose levels, and commonly have problems with obesity and cardiovascular disease. Patients are treated with standard diet, insulin, diabetic oral agents and antihypertensive drugs, but this approach does not completely stops tissue deterioration since it does not address the metabolic root of the disease. Metabolic correction is proposed as a suitable adjunct treatment to improve clinical outcomes. Metabolic correction is based on diet modification, proper hydration and scientific supplementation directed to improve cellular biochemistry and metabolic efficiency. In addition, other possible benefits may include reduction in medication use, disease complications and medical costs. To test the results of a metabolic correction program, 25 patients with DM2 participated in an education program about adequate food consumption that promoted control of blood glucose levels. Anthropometric measurements and blood tests were performed during a 13 week program based on a low carbohydrate diet, proper hydration and magnesium supplementation. The metabolic correction program implemented by a proprietary educational system resulted in significant reductions in glucose, triglycerides, cholesterol, weight and waist circumference. Improvements in these values could represent an important reduction of coronary heart disease risk factors as well as other chronic degenerative diseases. In addition there was medication dosage reduction in one or more medications in 21 of the 25 participating patients, which suggest that the program has the potential to improve health outcomes and reduce health care costs.

    Diabetes Mellitus type 2 (DM2) is a metabolic disease that develops by a decrease in sensitivity of insulin receptors as an effect of the disruption certain metabolic functions in the processing of glucose. DM2 patients have, uncontrolled glucose levels, and commonly have problems with obesity and cardiovascular disease. Patients are treated with standard diet, insulin, diabetic oral agents and antihypertensive drugs, but this approach does not completely stops tissue deterioration since it does not address the metabolic root of the disease. Metabolic correction is proposed as a suitable adjunct treatment to improve clinical outcomes. Metabolic correction is based on diet modification, proper hydration and scientific supplementation directed to improve cellular biochemistry and metabolic efficiency. In addition, other possible benefits may include reduction in medication use, disease complications and medical costs.

    Bone fractures in patients with diabetes mellitus heal poorly and require innovative therapies to support bone regeneration. Here, we assessed whether sulfated hyaluronan included in collagen-based scaffold coatings can improve fracture healing in diabetic rats. Macroporous thermopolymerized lactide-based scaffolds were coated with collagen including non-sulfated or sulfated hyaluronan (HA/sHA3) and inserted into 3 mm femoral defects of non-diabetic and diabetic ZDF rats. After 12 weeks, scaffolds coated with collagen/HA or collagen/sHA3 accelerated bone defect regeneration in diabetic, but not in non-diabetic rats as compared to their non-coated controls. At the tissue level, collagen/sHA3 promoted bone mineralization and decreased the amount of non-mineralized bone matrix. Moreover, collagen/sHA3-coated scaffolds from diabetic rats bound more sclerostin in vivo than the respective controls. Binding assays confirmed a high binding affinity of sHA3 to sclerostin. In vitro, sHA3 induced BMP-2 and lowered the RANKL/OPG expression ratio, regardless of the glucose concentration in osteoblastic cells. Both sHA3 and high glucose concentrations decreased the differentiation of osteoclastic cells. In summary, scaffolds coated with collagen/sHA3 represent a potentially suitable biomaterial to improve bone defect regeneration in diabetic conditions. The underlying mechanism involves improved osteoblast function and binding sclerostin, a potent inhibitor of Wnt signaling and osteoblast function. PMID:27131598

    Background Diabetes is an emerging risk factor for hepatocellular carcinoma (HCC), but prospective data from different ethnic populations are scarce. We examined the association between diabetes and HCC in 168679 African Americans, Native Hawaiians, Japanese Americans, Latinos and whites in the Multiethnic Cohort. Methods During a 15.7-year follow up period, 470 incident HCC cases were identified. Risk factor data were obtained from the baseline questionnaire. Cox regressions were used to calculate hazard rate ratios (RRs) and 95% confidence intervals (CIs) for HCC associated with self-reported diabetes. The population attributable risk percent associated with diabetes was also calculated. All statistical tests were two-sided. Results The RRs for developing HCC (vs whites) were 2.73 (95% CI = 2.00 to 3.72) for Latinos, 2.48 (95% CI = 1.59 to 3.87) for Hawaiians, 2.16 (95% CI = 1.52 to 3.07) for African Americans, and 2.05 (95% CI = 1.50 to 2.81) for Japanese. Diabetes was associated with HCC across ethnic groups (RRLatinos = 3.36 [95% CI = 2.41 to 4.70], RRHawaiians = 2.50 [95% CI = 1.11 to 5.64], RRJapanese = 2.34 [95% CI = 1.60 to 3.41], RRwhites = 2.15 [95% CI = 0.95 to 4.90], and RRAfrican Americans = 2.02 [95% CI = 1.17 to 3.48]). We estimated that 27% of HCC cases in Latinos, 18% in Hawaiians, 13% in African Americans, 12% in Japanese, and 6% in whites were attributed to diabetes. Conclusions Latinos were at the highest risk of developing HCC, followed by Native Hawaiians, African Americans, Japanese and whites. Diabetes is a risk factor for HCC in all ethnic groups, and eliminating diabetes could potentially reduce HCC incidence in all ethnic groups, with the largest potential for reduction in Latinos.

    Insulin resistance (IR) is a precursor of type 2 diabetes (T2D), and improved risk prediction and understanding of the pathogenesis are needed. We used a novel high-throughput 92-protein assay to identify circulating biomarkers for HOMA of IR in two cohorts of community residents without diabetes (n = 1,367) (mean age 73 ± 3.6 years). Adjusted linear regression identified cathepsin D and confirmed six proteins (leptin, renin, interleukin-1 receptor antagonist [IL-1ra], hepatocyte growth factor, fatty acid-binding protein 4, and tissue plasminogen activator [t-PA]) as IR biomarkers. Mendelian randomization analysis indicated a positive causal effect of IR on t-PA concentrations. Two biomarkers, IL-1ra (hazard ratio [HR] 1.28, 95% CI 1.03-1.59) and t-PA (HR 1.30, 1.02-1.65) were associated with incident T2D, and t-PA predicted 5-year transition to hyperglycemia (odds ratio 1.30, 95% CI 1.02-1.65). Additional adjustment for fasting glucose rendered both coefficients insignificant and revealed an association between renin and T2D (HR 0.79, 0.62-0.99). LASSO regression suggested a risk model including IL-1ra, t-PA, and the Framingham Offspring Study T2D score, but prediction improvement was nonsignificant (difference in C-index 0.02, 95% CI -0.08 to 0.12) over the T2D score only. In conclusion, proteomic blood profiling indicated cathepsin D as a new IR biomarker and suggested a causal effect of IR on t-PA. PMID:26420861

    In addition to race and ethnicity, specific geographic regions are associated with poorer outcomes of care. Individuals with diabetes experiencing health disparities typically have worse long-term outcomes, such as increased diabetes complications and mortality. Zip code mapping, or geocoding, was utilized in this study to identify regions of the United States with high diabetes prevalence rates and to identify areas with high densities of minority populations. Use of this methodology to examine the effect of disease management on a large, diverse diabetes population revealed greater improvement in clinical testing rates in health disparity zones compared with members living outside of these areas. In particular, significant improvement was achieved by members living in minority zip codes and by members aged 65 years or older. These findings demonstrate that members living in areas of health disparity obtain even greater benefit from diabetes disease management program participation, helping to reduce gaps in care.

    Abstract Background: Body sway increases in the elderly because of normal aging and high incidence of disease such as diabetes. Prevalence of sway is greater in the elderly with diabetes because of damage to the central and peripheral nervous systems. Increase in body sway is associated with an elevated risk of falling. Falling is one of the major causes of morbidity and mortality in the elderly. The purpose of this study was to develop a new technique to improve body stability and decrease body sway in the elderly people with or without diabetes. Subjects and Methods: Twenty-two subjects—12 elderly (mean age, 75.5±7.3 years) and 10 age-matched elderly with diabetes (mean age, 72.5±5.3 years)—were recruited for this study. Subjects received tactile feedback as a tingling sensation resulting from electrical stimulation triggered by body sway. Results: The results showed a significant reduction in body sway in the elderly while standing on foam with eyes open (1.0±0.31 vs. 1.9±0.8; P=0.006) and eyes closed (1.8±0.7 vs. 3.3±1.5; P=0.001). In the group with diabetes, there was a significant reduction in body sway while standing on foam with eyes closed (1.4±0.5 vs. 2.3±0.8; P=0.045) but not with eyes open. Conclusions: In this small study, this technique offers a new tool for training people with diabetes and elderly people to improve body stability and balance. PMID:25299792

    Urine concentration is regulated by vasopressin. Congenital nephrogenic diabetes insipidus (NDI) is caused by vasopressin type 2 receptor (V2R) mutations. We studied whether metformin could improve urine concentration in rodent models of congenital NDI by stimulating AMPK. To block the V2R in rats, tolvaptan (10 mg/kg/d) was given by oral gavage with or without metformin (800 mg/kg/d). Control rats received vehicle with or without metformin. Tamoxifen-induced V2R KO mice were given metformin (600 mg/kg) or vehicle twice daily. Urine osmolality in tolvaptan-treated rats (1,303 ± 126 mOsM) was restored to control levels by metformin (2,335 ± 273 mOsM) within 3 days and was sustained for up to 10 days. Metformin increased protein abundance of inner medullary urea transporter UT-A1 by 61% and aquaporin 2 (AQP2) by 44% in tolvaptan-treated rats, and immunohistochemistry showed increased membrane accumulation of AQP2 with acute and chronic AMPK stimulation. Outer medullary Na+-K+-2Cl– cotransporter 2 (NKCC2) abundance increased (117%) with AMPK stimulation in control rats but not in V2R-blocked rats. Metformin increased V2R KO mouse urine osmolality within 3 hours, and the increase persisted for up to 12 hours. Metformin increased AQP2 in the V2R KO mice similar to the tolvaptan-treated rats. These results indicate that AMPK activators, such as metformin, might provide a promising treatment for congenital NDI. PMID:27478876

    Individuals with long-standing type 1 diabetes (T1D) are at increased risk of severe hypoglycemia secondary to impairments in normal glucose counterregulatory responses (CRRs). Strategies to prevent hypoglycemia are often ineffective, highlighting the need for novel therapies. ATP-sensitive potassium (KATP) channels within the hypothalamus are thought to be integral to hypoglycemia detection and initiation of CRRs; however, to date this has not been confirmed in human subjects. In this study, we examined whether the KATP channel-activator diazoxide was able to amplify the CRR to hypoglycemia in T1D subjects with long-duration diabetes. A randomized, double-blind, placebo-controlled cross-over trial using a stepped hyperinsulinemic hypoglycemia clamp was performed in 12 T1D subjects with prior ingestion of diazoxide (7 mg/kg) or placebo. Diazoxide resulted in a 37% increase in plasma levels of epinephrine and a 44% increase in plasma norepinephrine during hypoglycemia compared with placebo. In addition, a subgroup analysis revealed that the response to oral diazoxide was blunted in participants with E23K polymorphism in the KATP channel. This study has therefore shown for the first time the potential utility of KATP channel activators to improve CRRs to hypoglycemia in individuals with T1D and, moreover, that it may be possible to stratify therapeutic approaches by genotype.

    The incidence of sternal wound infections (SWI) after coronary artery bypass surgery (CABG) as reported worldwide is low. However, it is associated with significant increase of postoperative mortality and treatment costs. The major risk factors discussed are diabetes mellitus and bilateral IMA harvesting of the internal mammary artery. This study analyses data of 590 patients receiving CABG concerning the risk factors for SWI. Sternal wound infections occur significantly more often in diabetic patients, one crucial and significant additional risk factor is obesity. PMID:27547690

    A cross sectional descriptive study was carried out to determine the prevalence and risk factors of diabetes mellitus among adults in Jaffna District. Multistage stratified cluster sampling technique was employed to select 544 participants. An interviewer administrated questionnaire was used. Anthropometric and blood pressure (BP) measurements were recorded and biochemical parameters were analysed. Response rate was 95.3%. Of them, 224 (43.8%) were male. The prevalence of diabetes mellitus was 16.4% (95% CI: 13.3- 19.9); in males 19.6% (95% CI: 14.6-25.4) and in females 13.9% (95% CI: 10.1-18.5). Of the diabetics, 27.4% were previously undiagnosed. In the final multivariable model, participants with family history of diabetes were 3.5 times (p<0.001) more likely and those with high waist hip ratio were 2 times (p=0.009) more likely to develop diabetes mellitus.

    A recent increase in the incidence of diabetes and pre-diabetes is causing many employers to spend more of their healthcare benefit budgets to manage the conditions. A self-insured university in the USA has implemented an interprofessional diabetes mellitus risk reduction program using its own employee faculty and staff experts to help fellow employees manage their diabetes and pre-diabetes. The interprofessional team consists of five pharmacists, a dietitian, an exercise physiologist, a health educator and a licensed mental health practitioner. In addition, the participant's physician serves as a consultant to the program, as does a human resources healthcare benefits specialist and a wellness coordinator. The volunteer program takes place at the worksite during regular business hours and is free of charge to the employees. The faculty and staff delivering the program justify the cost of their time through an interprofessional educational model that the program will soon provide to university students. PMID:22957897

    Abstract Hepatitis C virus (HCV) infection and type 2 diabetes mellitus (T2DM) present a significant health burden, with increasing complications and mortality rates worldwide. Pycnogenol® (PYC), a natural product, possesses antidiabetic and antiviral properties that may improve HCV-associated T2DM. In this review, we present previously published data on the effectiveness of PYC against HCV replication and T2DM. We believe that supplementing conventional treatment with PYC may improve the current HCV therapy, attenuate HCV-associated T2DM, and reduce the risk of complications such as cirrhosis or hepatocellular carcinoma and cardiovascular disease.

    Background When quality improvement processes are integrated into resident education, many opportunities are created for improved outcomes in patient care. For Bethesda Family Medicine (BFM), integrating quality improvement into resident education is paramount in fulfilling the Accreditation Council for Graduate Medical Education Practice-Based Learning and Improvement core competency requirements. Methods A resident-developed diabetes management treatment protocol that targeted 11 evidence-based measures recommended for successful diabetes management was implemented within the BFM residency and all physician practices under its parent healthcare system. This study compares diabetes management at BFM and at 2 other family medicine practices at timepoints before and after protocol implementation. We measured hemoglobin A1c (HbA1c), low-density lipoprotein (LDL) cholesterol, and systolic blood pressure (SBP) in adult diabetics and compared patient outcomes for these measures for the first and third quarters of 2009 and 2010. Results In BFM patients, HbA1c, LDL, and SBP levels decreased, but only HbA1c improvement persisted long term. For the comparison groups, in general levels were lower than those of BFM patients but not significantly so after the first measurement period. Conclusions A resident-led treatment protocol can improve HbA1c outcomes among residents' diabetic patients. Periodic educational interventions can enhance residents' focus on diabetes management. Residents in graduate medical education can initiate treatment protocols to improve patient care in a large healthcare system. PMID:23267258

    Background: A widely held hypothesis is that interactions between genetic predisposition and Western-type lifestyle contribute to the epidemic of type 2 diabetes (T2D). No study has tested this hypothesis. Objective: The objective was to assess whether established genetic variants, mainly from genomewide association studies, modify dietary patterns in predicting diabetes risk. Design: We determined 10 polymorphisms in a prospective, nested, case-control study of 1196 diabetic and 1337 nondiabetic men. A genetic risk score (GRS) was generated by using an allele counting method. Baseline dietary intakes were collected by using a semiquantitative food-frequency questionnaire. We used factor analysis to derive Western and “Prudent” dietary patterns from 40 food groups. Results: A significant interaction (P = 0.02) was observed between the GRS and Western dietary pattern. The multivariable odds ratios (ORs) of T2D across increasing quartiles for the Western dietary pattern were 1.00, 1.23 (95% CI: 0.88, 1.73), 1.49 (1.06,2.09), and 2.06 (1.48, 2.88) among men with a high GRS (≥12 risk alleles; P for trend = 0.01). The Western dietary pattern was not associated with diabetes risk among those with a lower GRS. In addition, we found that intakes of processed meat, red meat, and heme iron, which characterized the Western dietary pattern, showed significant interactions with GRS in relation to diabetes risk (P for interaction = 0.029, 0.02, and 0.0004, respectively). The diet-diabetes associations were more evident among men with a high GRS (≥12) than in those with a low GRS. Conclusion: Genetic predisposition may synergistically interact with a Western dietary pattern in determining diabetes risk in men. PMID:19279076

    Aim Dietary patterns have been associated with type 2 diabetes incidence, but little is known about the impact of ethnicity on this relation. This study evaluated the association of four a priori dietary quality indexes and type 2 diabetes risk among whites, Japanese Americans, and Native Hawaiians in the Hawaii component of the Multiethnic Cohort (MEC). Methods After excluding participants with prevalent diabetes and missing values, the analysis included 89,185 participants (11,217 cases). Dietary intake was assessed at baseline with a quantitative food frequency questionnaire designed for use in the relevant ethnic populations. Sex- and ethnicity-specific hazard ratios were calculated for the Healthy Eating Index-2010 (HEI-2010), the alternative HEI-2010 (AHEI-2010), the alternate Mediterranean diet score (aMED), and the Dietary Approaches to Stop Hypertension (DASH). Results We observed significant inverse associations between higher scores of the DASH index and type 2 diabetes risk in white men and women, as well as in Japanese American women and Native Hawaiian men with respective risk reductions of 37, 31, 19 and 21% (highest compared to lowest index category). A higher adherence to the AHEI-2010 and aMED diet was related to a 13–28% lower type 2 diabetes risk in white participants but not in other ethnic groups. No significant associations with type 2 diabetes risk were observed for the HEI-2010 index. Conclusions The small ethnic differences in type 2 diabetes risk associated with scores of a priori-defined dietary patterns may be due to different consumption patterns of food components and the fact that the original indexes were not based on Asians and Pacific Islanders.

    An alarming increase the prevalence of type 2 diabetes is forcing to constant analysis the lifestyle factors which can affect the risk of this illness. The research in the last ten years revealed new knowledge concerning the inverse association between habitual coffee drinking and risk of type 2 diabetes. The study indicate that people who drink at least 3 cups of coffee per day more seldom have diabetes and positive effect of coffee is rising along with the amount of the coffee in the diet. It is not clear what mechanism may be responsible for such association but the attention is focus mainly on caffeine, polyphenols, magnesium. Because of the fact that high coffee consumption can cause other adverse health effects coffee should not be treat as a public health strategy to prevent type 2 diabetes, but collected data have scientific character at the moment.

    Patients with diabetes have greatly elevated risks of atherosclerotic diseases such as coronary artery disease (CAD) and stroke. Vascular calcification in advanced atherosclerosis is a common feature in diabetic patients. In vitro and in vivo studies suggest that apoptosis and chondro/osteogenic differentiation of vascular wall cells such as smooth muscle cells may play important roles in the progression of vascular calcification. Diabetes may promote vascular calcification through the action of various factors including hyperglycemia, oxidative stress, tumor necrosis factor-alpha, and advanced glycation end products. Detection of coronary calcium by electron-beam computed tomography (EBCT) revealed clinical significance of vascular calcification and this technique may be a useful method to identify diabetic patients with increased risks of cardiovascular disease and stroke.

    Background The impact of long working hours on diabetes is controversial; however, shift work is known to increase the risk of diabetes. This study aimed to investigate the association between long working hours and diabetes among civil servants in Japan separately by shift work schedules. Methods A prospective cohort study was conducted from April 2003 to March 2009. A total of 3195 men aged ≥35 years who underwent an annual health checkup at baseline were analyzed by shift work schedules (2371 non-shift workers and 824 shift workers). Self-reported working hours were categorized as 35–44 and ≥45 hours per week. The incidence of diabetes was confirmed by fasting plasma glucose concentration ≥126 mg/dL and/or self-reported medical diagnosis of diabetes at the annual checkup. A Cox proportional model was used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) for developing diabetes associated with long working hours. Results The median follow-up period of non-shift and shift workers was 5.0 and 4.9 years, respectively. During this period, 138 non-shift workers and 46 shift workers developed diabetes. A decreased HR was found among non-shift workers working ≥45 hours per week (HR 0.84; 95% CI, 0.57–1.24); however, shift workers working ≥45 hours per week had a significantly increased risk of diabetes (HR 2.43; 95% CI, 1.21–5.10) compared with those working 35–44 hours per week. An analysis restricted to non-clerical workers also showed similar results. Conclusions The risk of diabetes associated with long working hours differed by shift work schedules. PMID:27001115

    Pre-diabetes, which is typically defined as blood glucose concentrations higher than normal but lower than the diabetes threshold, is a high-risk state for diabetes and cardiovascular disease development. As such, it represents three groups of individuals: Those with impaired fasting glucose (IFG), those with impaired glucose tolerance (IGT) and those with a glycated haemoglobin (HbA1c) between 39-46 mmol/mol. Several clinical trials have shown the important role of IFG, IGT and HbA1c-pre-diabetes as predictive tools for the risk of developing type 2 diabetes. Moreover, with regard to cardiovascular disease, pre-diabetes is associated with more advanced vascular damage compared with normoglycaemia, independently of confounding factors. In view of these observations, diagnosis of pre-diabetes is mandatory to prevent or delay the development of the disease and its complications; however, a number of previous studies reported that the concordance between pre-diabetes diagnoses made by IFG, IGT or HbA1c is scarce and there are conflicting data as to which of these methods best predicts cardiovascular disease. This review highlights recent studies and current controversies in the field. In consideration of the expected increased use of HbA1c as a screening tool to identify individuals with alteration of glycaemic homeostasis, we focused on the evidence regarding the ability of HbA1c as a diagnostic tool for pre-diabetes and as a useful marker in identifying patients who have an increased risk for cardiovascular disease. Finally, we reviewed the current evidence regarding non-traditional glycaemic biomarkers and their use as alternatives to or additions to traditional ones. PMID:27795816

    In the early 2000s, the prevalence of diabetes in adults aged ≥30 years in Korea was about 9% to 10%, and it remained stable. However, a nationwide survey showed that this prevalence increased over the past few years. After age-standardization using the Korean population of the year 2010, the prevalence of diabetes in adults aged ≥30 years was 10.0% to 10.8% between 2001 and 2012, which increased to 12.5% in 2013 and 11.6% in 2014. During that period, there have been changes in the gender- and age-specific prevalence of diabetes in Korean adults. The prevalence of diabetes in the elderly population increased significantly, while this prevalence in young adults, especially in young women, did not change significantly. The contribution of each diabetic risk factor, such as obesity, β-cell dysfunction, sarcopenia, and socioeconomic status, in developing diabetes has also changed during that period in each gender and age group. For young women, obesity was the most important risk factor; by contrast, for elderly diabetic patients, sarcopenia was more important than obesity as a risk factor. Considering the economic burden of diabetes and its associated comorbidities, a public health policy targeting the major risk factors in each population might be more effective in preventing diabetes.

    Short-term breastfeeding and early exposure to complex dietary proteins, such as cow milk proteins and cereals, or to fruit, berries, and roots have been implicated as risk factors for β cell autoimmunity, clinical type 1 diabetes, or both. The Trial to Reduce Insulin-dependent diabetes mellitus in the Genetically at Risk (TRIGR) is an international, randomized, double-blind, controlled intervention trial designed to answer the question of whether weaning to an extensively hydrolyzed formula in infancy will decrease the risk of type 1 diabetes later in childhood. In our pilot study, weaning to a highly hydrolyzed formula decreased by ≈ 50% the cumulative incidence of one or more diabetes-associated autoantibodies by a mean age of 4.7 y. This finding was confirmed in a recent follow-up analysis to 10 y of age. Currently, the full-scale TRIGR takes place in 77 centers in 15 countries. The TRIGR initially recruited 5606 newborn infants with a family member affected by type 1 diabetes and enrolled 2159 eligible subjects who carried a risk-conferring HLA genotype. All recruited mothers were encouraged to breastfeed. The intervention lasted for 6-8 mo with a minimum study formula exposure time of 2 mo, and hydrolyzed casein and standard cow milk-based weaning formulas were compared. Eighty percent of the participants were exposed to the study formula. The overall retention rate over the first 5 y was 87%, and protocol compliance was 94%. The randomization code will be opened when the last recruited child turns 10 y of age (ie, in 2017).

    Our study describes the incidence and risk factors for undiagnosed diabetes in elderly cancer patients. Using Surveillance, Epidemiology, and End Results-Medicare data, we followed patients with breast, colorectal, lung, or prostate cancer from 24 months before to 3 months after cancer diagnosis. Medicare claims were used to exclude patients with diabetes 24 to 4 months before cancer (look-back period), identify those with diabetes undiagnosed until cancer, and construct indicators of preventive services, physician contact, and comorbidity during the look-back period. Logistic regression analyses were performed to identify factors associated with undiagnosed diabetes. Overall, 2,678 patients had diabetes undiagnosed until cancer. Rates were the highest in patients with both advanced-stage cancer and low prior primary care/medical specialist contact (breast 8.2%, colorectal 5.9%, lung 4.4%). Nonwhite race/ethnicity, living in a census tract with a higher percent of the population in poverty and a lower percent college educated, lower prior preventive services use, and lack of primary care and/or medical specialist care prior to cancer all were associated with higher (P ≤ 0.05) adjusted odds of undiagnosed diabetes. Undiagnosed diabetes is relatively common in selected subgroups of cancer patients, including those already at high risk of poor outcomes due to advanced cancer stage.

    Rates of elevated urinary albumin concentration, defined as microalbuminuria (30-299 micrograms/ml) and macroalbuminuria (greater than or equal to 300 micrograms/ml), were determined on random morning urine specimens in the population of Nauru, which has a high prevalence of non-insulin-dependent diabetes mellitus. The prevalence of elevated urinary albumin levels in the total Nauruan population was very high: 26 and 30% of men and women, respectively, had microalbuminuria, whereas 13% of both sexes had macroalbuminuria. Of the subjects with macroalbuminuria, 66% had diabetes. The prevalence increased with worsening glucose tolerance; 26% of subjects with normal glucose tolerance had either micro- or macroalbuminuria, increasing to 43% of subjects with impaired glucose tolerance, 63% of newly diagnosed diabetic subjects, and 75% of previously diagnosed diabetic subjects. Associations between elevated urinary albumin concentration and putative risk factors were assessed for both the total population (n = 1184) and the diabetic subgroup alone (n = 318). Fasting plasma glucose and hypertension were the most important independent correlates for the whole population, whereas plasma creatinine was also important in diabetic subjects. Age at onset and duration of diabetes were not found to be significantly associated with elevated albumin concentration. In subjects with normal glucose tolerance, hypertension and hyperuricemia were the most important associated factors. These results suggest that blood glucose, blood pressure, and possibly obesity and plasma uric acid are important modifiable risk factors for both micro- and macroalbuminuria in this population.

    Background Retinol binding protein 4 (RBP4) has been described as a link between impaired glucose uptake in adipocytes and systemic insulin sensitivity. Objective To determine whether RBP4 fasting levels predict the development of type 2 diabetes. Methods Using a case-cohort design, we followed 543 middle-aged individuals who developed diabetes and 537 who did not over ~9 years within the population-based Atherosclerosis Risk in Communities Study. Weighted Cox proportional hazards analyses permitted statistical inference of the RBP4 – incident diabetes associations to the entire cohort. Results Women in the highest tertile of RBP4 presented greater risk of developing diabetes (HR=1.74; 95%CI 1.03–2.94) in analyses adjusted for age, ethnicity, study center, parental history of diabetes, hypertension, glomerular filtration rate, body mass index, waist-hip ratio, nonesterified fatty acids, adiponectin, leptin, triglycerides and HDL-C. When additionally adjusted for fasting insulin, this association’s significance became borderline (HR=1.68; 95%CI 1.00–2.82). No association between RBP4 levels and incident diabetes was found in men. Conclusion These findings suggest that RBP4 levels may be directly involved in the pathogenesis of type 2 diabetes in women.

    The current epidemiologic evidence suggests that men with type 2 diabetes mellitus may be at lower risk of developing prostate cancer, but little is known about its association with stage and grade of the disease. The association between self-reported diabetes mellitus at recruitment and risk of prostate cancer was examined in the European Prospective Investigation into Cancer and Nutrition (EPIC). Among 139,131 eligible men, 4,531 were diagnosed with prostate cancer over an average follow-up of 12 years. Multivariable hazard ratios (HR) and 95% confidence intervals (CI) were estimated using Cox proportional hazards models stratified by EPIC-participating center and age at recruitment, and adjusted for education, smoking status, body mass index, waist circumference, and physical activity. In a subset of men without prostate cancer, the cross-sectional association between circulating concentrations of androgens and insulin-like growth factor proteins with diabetes status was also investigated using linear regression models. Compared to men with no diabetes, men with diabetes had a 26% lower risk of prostate cancer (HR, 0.74; 95% CI, 0.63-0.86). There was no evidence that the association differed by stage (p-heterogeneity, 0.19) or grade (p-heterogeneity, 0.48) of the disease, although the numbers were small in some disease subgroups. In a subset of 626 men with hormone measurements, circulating concentrations of androstenedione, total testosterone and insulin-like growth factor binding protein-three were lower in men with diabetes compared to men without diabetes. This large European study has confirmed an inverse association between self-reported diabetes mellitus and subsequent risk of prostate cancer.

    Diabetes mellitus increases the risk for hypertension and associated cardiovascular diseases, including coronary, cerebrovascular, renal and peripheral vascular disease. The risk for developing cardiovascular disease is increased when both diabetes and hypertension co-exist; in fact, over 11 million Americans have both diabetes and hypertension. These numbers will continue to climb, internationally, since the leading associated risk for diabetes development, obesity, has reached epidemic proportions, globally. Moreover, the frequent association of diabetes with dyslipidemia, as well as coagulation, endothelial, and metabolic abnormalities also aggravates the underlying vascular disease process in patients who possess these comorbid conditions. The renin-angiotensin-aldosterone system (RAS) and arginine vasopressin (AVP) are overactivated in both hypertension and diabetes. Drugs that inhibit this system, such as ACE inhibitors and more recently angiotensin receptor antagonists (ARBs), have proven beneficial effects on the micro- and macrovascular complications of diabetes, especially the kidney. The BRILLIANT study showed that lisinopril reduces microalbuminuria better than CCB therapy. Numerous other long-term studies confirm this association with ACE inhibitors including the HOPE trial. Furthermore, the European Controlled trial of Lisinopril in Insulin-dependent Diabetes (EUCLID) study, showed that lisinopril slowed the progression of renal disease, even in individuals with mild albuminuria. In fact, there are now five appropriately powered randomized placebo-controlled trials to show that both ACE inhibitors and ARBs slow progression of diabetic nephropathy in people with type 2 diabetes. These effects were shown to be better than conventional blood pressure lowering therapy, including dihydropyridine CCBs. In patients with microalbuminuria, ACE inhibitors and ARBs reduce the progression of microalbuminuria to proteinuria and provide a risk reduction of between

    Several studies have now reported associations between gestational diabetes mellitus (GDM) and low free thyroxine (fT4) during the second and third trimesters, but not in the first trimester. The present study further examines relationships between low fT4, maternal weight, and GDM among women in the FaSTER (First and Second Trimester Evaluation of Risk) trial, in an effort to determine the extent to which thyroid hormones might contribute to causality. The FaSTER cohort includes 9351 singleton, euthyroid women; 272 of these women were subsequently classified as having GDM. Thyrotropin (TSH), fT4, and thyroid antibodies were measured at 11-14 weeks' gestation (first trimester) and 15-18.9 weeks' gestation (second trimester). An earlier report of this cohort documented an inverse relationship between fT4 in the second trimester and maternal weight. In the current analysis, women with GDM were significantly older (32 vs. 28 years) and weighed more (75 vs. 64.5 kg). Maternal weight and age (but not TSH) were significantly associated univariately with fT4 (dependent variable), in the order listed. Second trimester fT4 odds ratios (OR) for GDM were 2.06 [95% CI 1.37-3.09] (unadjusted); and 1.89 [95% CI 1.26-2.84] (adjusted). First trimester odds ratios were not significant: OR 1.45 [95%CI 0.97-2.16] (unadjusted) and 1.11 [95% CI 0.74-1.62] (adjusted). The second trimester fT4/GDM relationship thus appeared to strengthen as gestation progressed. In FaSTER, high maternal weight was associated with both low fT4 and a higher GDM rate in the second trimester. Peripheral deiodinase activity is known to increase with high caloric intake (represented by high weight). We speculate that weight-related low fT4 (the metabolically inactive prohormone) is a marker for deiodinase activity, serving as a substrate for conversion of fT4 to free triiodothyronine (fT3), the active hormone responsible for glucose-related metabolic activity.

    Diabetes mellitus and depressive disorders are both common chronic diseases that increase functional disability and social burden. Cognitive impairment is a potentially debilitating feature of depression. Previous evidence indicates that the antidiabetic drug metformin could be suitable for diabetic patients with cognitive impairment. However, there is no direct evidence from clinical studies that metformin treatment improves cognitive function in diabetic patients suffering from depression. In the present study, 58 participants diagnosed with depression and type 2 diabetes mellitus (T2DM) were recruited and divided into two groups, one treated with metformin and the other treated with placebo for 24 weeks. Cognitive function, depressive behaviour and diabetes improvement were evaluated. Chronic treatment with metformin for 24 weeks improved cognitive performance, as assessed by the Wechsler Memory Scale-Revised, in depressed patients with T2DM. In addition, metformin significantly improved depressive performance and changed the glucose metabolism in depressed patients with diabetes. Depressive symptoms were negatively correlated with cognitive performance in metformin-treated participants. Furthermore, associations were observed between the parameters of blood glucose metabolism and the depression phenotype. These findings suggest that chronic treatment with metformin has antidepressant behavioural effects and that improved cognitive function is involved in the therapeutic outcome of metformin. The results of the present study also raise the possibility that supplementary administration of antidiabetic medications may enhance the recovery of depression, comorbid with T2DM, through improvements in cognitive performance.

    Comorbid depression is common in patients with type 2 diabetes mellitus and is associated with greater mortality risk and a higher incidence of diabetic complications and decreased quality of life. In an earlier pilot study, we found that treatment with the serotonin norepinephrine reuptake inhibitor antidepressant, milnacipran, significantly improved metabolic parameters in diabetic patients with comorbid depression who had an antidepressant response. We sought to replicate these results in a larger cohort (n = 135). Patients received milnacipran and metformin for 6 months and metabolic parameters and depressive symptoms were measured at baseline and after 3 and 6 months. At the end of the study, 72.6% of patients had an antidepressant response (≥50% reduction of baseline Beck Depression Inventory score). Overall, there was significant improvement in the metabolic and anthropometric parameters measured. The number of patients with glycated hemoglobin > 8% (>63.9 mmol/mol), an indicator of poor metabolic control requiring intensive therapeutic intervention, decreased from 31.9% at baseline to 11.9% during the study. As found in the pilot study, levels of total cholesterol and triglycerides were only significantly decreased in antidepressant responders. Body weight was significantly reduced in both responders and nonresponders but the effect size was significantly greater in the responder group. In contrast to the pilot study, fasting blood glucose and glycated hemoglobin were significantly decreased to a similar extent in both antidepressant-responders and nonresponders. The present study thus replicates some of the original findings. The main difference between the present and the pilot study is that in the larger cohort significant reductions in fasting blood glucose and glycated hemoglobin were found in all patients irrespective of whether or not they responded to antidepressant treatment. The present data underline the importance of diagnosis and treatment of

    The results of recent outcome trials challenge hypotheses that tight control of both glycohemoglobin and blood pressure diminishes macrovascular events and survival among type 2 diabetic patients. Relevant questions exist regarding the adequacy of glycohemoglobin alone as a measure of diabetes control. Are we ignoring mechanisms of vasculotoxicity (profibrosis, altered angiogenesis, hypertrophy, hyperplasia, and endothelial injury) inherent in current antihyperglycemic medications? Is the polypharmacy for lowering cholesterol, triglyceride, glucose, and systolic blood pressure producing drug interactions that are too complex to be clinically identified? We review angiotensin–aldosterone mechanisms of tissue injury that magnify microvascular damage caused by hyperglycemia and hypertension. Many studies describe interruption of these mechanisms, without hemodynamic consequence, in the preservation of function in type 1 diabetes. Possible interactions between the renin–angiotensin–aldosterone system and physiologic glycemic control (through pulsatile insulin release) suggest opportunities for further clinical investigation.

    It has recently been suggested that the low-frequency c.136-14_136-13insC variant in high-mobility group A1 (HMGA1) may strongly contribute to insulin resistance and type 2 diabetes risk. In our study, we attempted to confirm that HMGA1 is a novel type 2 diabetes locus in French Caucasians. The gene was sequenced in 368 type 2 diabetic case subjects with a family history of type 2 diabetes and 372 normoglycemic control subjects without a family history of type 2 diabetes. None of the 41 genetic variations identified were associated with type 2 diabetes. The lack of association between the c.136-14_136-13insC variant and type 2 diabetes was confirmed in an independent French group of 4,538 case subjects and 4,015 control subjects and in a large meta-analysis of 16,605 case subjects and 46,179 control subjects. Finally, this variant had no effects on metabolic traits and was not involved in variations of HMGA1 and insulin receptor (INSR) expressions. The c.136-14_136-13insC variant was not associated with type 2 diabetes in individuals of European descent. Our study emphasizes the need to analyze a large number of subjects to reliably assess the association of low-frequency variants with the disease. PMID:22210315

Our aim is to estimate the prevalence of clinical symptoms of gastroparesis among patients with type 2 diabetes mellitus and explore the relationship between gastroparesis and other risk factors. Methods A cross-sectional study evaluating 147 type 2 diabetics using the Gastroparesis Cardinal Symptoms Index (GCSI). A GCSI Total Score ≥ 1.90 were chosen as having definite symptoms of gastroparesis. All patients completed a demographic questionnaire and interviewed to complete the. Demographic Data, disease duration, Medication, comorbidities, recent blood glucose and HbA1C were collected and investigated. Results The prevalence of clinical symptoms of gastroparesis among type 2 diabetics was 10.8%. Clinical symptoms of gastroparesis were significantly correlated to HbA1c (p=0.001), blood glucose (p= 0.003), duration of diabetes (p= 0.02) and comorbidities (p=0.009). The most common symptoms were bloating, stomach fullness and early satiety (63.94%, 55.1% and 48.3% respectively). In logistic regression analysis, female gender emerged as significant independent predictors of the presence of at least one symptom. Conclusions The prevalence of clinical symptoms of gastroparesis observed in the Saudi patientsdiagnosedwithtype2 diabetes was 10.8% and is independently associated with poor controlled diabetes, hyperglycemia, and long duration of diabetes and history of Co-morbid conditions.

    Maternal diabetes increases the risk of congenital malformations in the offspring of affected pregnancies. This increase arises from the teratogenic effect of the maternal diabetic milieu on the developing embryo, although the mechanism of this action is poorly understood. In the present study, we examined whether the vitamin A metabolite retinoic acid (RA), a common drug with well-known teratogenic properties, may interact with maternal diabetes to alter the incidence of congenital malformations in mice. Our results show that when treated with RA, embryos of diabetic mice are significantly more prone than embryos of nondiabetic mice to develop caudal regression, a defect that is highly associated with diabetic pregnancy in humans. By studying the vestigial tail (Wnt-3a(vt)) mutant, we provide evidence that Wnt-3a, a gene that controls the development of the caudal region, is directly involved in the pathogenic pathway of RA-induced caudal regression. We further show that the molecular basis of the increased susceptibility of embryos of diabetic mice to RA involves enhanced downregulation of Wnt-3a expression. This positive interaction between RA and maternal diabetes may have implications for humans in suggesting increased susceptibility to environmental teratogens during diabetic pregnancy.

    Background The prevalence of gastroparesis in type 2 diabetes mellitus (T2DM) vary widely. Our aim is to estimate the prevalence of clinical symptoms of gastroparesis among patients with type 2 diabetes mellitus and explore the relationship between gastroparesis and other risk factors. Methods A cross-sectional study evaluating 147 type 2 diabetics using the Gastroparesis Cardinal Symptoms Index (GCSI). A GCSI Total Score ≥ 1.90 were chosen as having definite symptoms of gastroparesis. All patients completed a demographic questionnaire and interviewed to complete the. Demographic Data, disease duration, Medication, comorbidities, recent blood glucose and HbA1C were collected and investigated. Results The prevalence of clinical symptoms of gastroparesis among type 2 diabetics was 10.8%. Clinical symptoms of gastroparesis were significantly correlated to HbA1c (p=0.001), blood glucose (p= 0.003), duration of diabetes (p= 0.02) and comorbidities (p=0.009). The most common symptoms were bloating, stomach fullness and early satiety (63.94%, 55.1% and 48.3% respectively). In logistic regression analysis, female gender emerged as significant independent predictors of the presence of at least one symptom. Conclusions The prevalence of clinical symptoms of gastroparesis observed in the Saudi patientsdiagnosedwithtype2 diabetes was 10.8% and is independently associated with poor controlled diabetes, hyperglycemia, and long duration of diabetes and history of Co-morbid conditions.

    Aim Three urinary biomarkers, kidney injury molecule-1 (KIM-1), neutrophil gelatinase-associated lipocalin (NGAL), and cystatin C, have been suggested as clinically relevant highly specific biomarkers of acute kidney tubular damage. Yet, the utility of these biomarkers in the prognostication of diabetic nephropathy has been less studied. Therefore, we aimed to investigate the longitudinal association between these urinary biomarkers and cardiovascular mortality in patients with diabetes. Methods The study sample consisted of participants with diabetes in the community-based Uppsala Longitudinal Study of Adult Men (n = 91; mean age 77.8 years). During follow-up (median 8.3 years, interval 0.7–13.4 years), 33 participants died of cardiovascular causes. Results In a multivariable Cox regression model adjusting for age, glomerular filtration rate, and urinary albumin/creatinine ratio, higher urinary KIM-1/creatinine was associated with an increased risk for cardiovascular mortality (HR per SD increase 1.51, 95% confidence intervals 1.03–2.24, P = 0.03). Neither urinary NGAL/creatinine nor urinary cystatin C/creatinine were independently associated with an increased cardiovascular mortality risk. Conclusion In elderly men with diabetes, higher urinary KIM-1/creatinine was associated with an increased long-term risk of cardiovascular mortality independently of established markers of diabetic nephropathy. Our data provide support for kidney tubular damage as an important aspect of diabetic nephropathy that merits further investigation. PMID:27321055

    Insulin pumps are booming in pediatric diabetology. The objective of this study was to assess changes for children and adolescents with type 1 diabetes using a pump in terms of quality of life (QOL), satisfaction, and glycosylated hemoglobin. A retrospective self-evaluation questionnaire was distributed to 41 patients. It focused on general QOL, diabetes-specific QOL supplemented by specific questions on the pump, and satisfaction. Clinical and biological parameters (glycated hemoglobin: HbA1c) were compared before and after pump use. The score for QOL with the pump was positive, more so if started early after diagnosis of diabetes (P=0.03) and with children under the age of 8 years (P<0.02). These positive results are mainly related to the characteristics of the pump, "insulin management" and "injections," as well as "diabetes management," "behavior," "school," "family life," "daily life," and "physical activities." On the other hand, the improvement was not significant for the item "life in society, friends and family." A decrease in the number of injections and the flexibility of meals were the most positive points. HbA1c improved as soon as the pump was indicated before its use was begun (P=0.005) and remained constant for 4 years (P≤0.05). Forgotten injections, comments on diabetes, and technical problems appeared to be exceptional. The pump changed the patient's body image because of ambivalent feelings between being normal (greater freedom) and different (visibility and a reminder of the disease). The benefits in terms of QOL and glycemic control with the pump cannot be dissociated and can only be considered accompanied by paramedical and medical assistance. Improving QOL over the short and long term by reducing the risk of further complications is the daily challenge of families and diabetologists.

    OBJECTIVE The purpose of this study was to determine the impact of sex and race/ethnicity on metabolic risk and health behaviors in minority youth. RESEARCH DESIGN AND METHODS A total of 173 seventh graders (46% male and 54% female; 49% Hispanic and 51% African American) with BMI ≥85th percentile and a family history of diabetes were assessed with weight, height, BMI, percent body fat, and waist circumference measures. Laboratory indexes included 2-h oral glucose tolerance tests with insulin levels at 0 and 2 h, fasting A1C, and lipids. Insulin resistance was estimated by homeostasis model assessment (HOMA-IR). Youth also completed questionnaires evaluating health behaviors. RESULTS Average BMI (31.6 ± 6.4 kg/m2) and percent body fat (39.5 ± 10.6%) were high. All participants demonstrated insulin resistance with elevated HOMA-IR values (8.5 ± 5.2). Compared with African American youth, Hispanic youth had higher triglycerides and lower HDL cholesterol despite similar BMI. Hispanic youth reported lower self-efficacy for diet, less physical activity, and higher total fat intake. Male youth had higher glucose (0 and 2 h) and reported more physical activity, more healthy food choices, and higher calcium intake than female youth. CONCLUSIONS Screening high-risk youth for insulin resistance and lipid abnormalities is recommended. Promoting acceptable physical activities and healthy food choices may be especially important for Hispanic and female youth. PMID:20855552

    A newly identified polysaccharide (PSG-1) has been purified from Ganoderma atrum. The study was to investigate the protective effect of PSG-1 on diabetes-induced endothelial dysfunction in rat aorta. Rats were fed a high fat diet for 8 weeks and then injected with a low dose of streptozotocin to induce type 2 diabetes. The diabetic rats were orally treated with PSG-1 for 4 weeks. It was found that administration of PSG-1 significantly reduced levels of fasting blood glucose, improved endothelium-dependent aortic relaxation, increased levels of phosphoinositide 3-kinase (PI3K), phospho-Akt (p-Akt), endothelial nitric oxide synthase (eNOS) and nitric oxide in the aorta from diabetic rats, compared to un-treated diabetics. These results suggested that the protective effects of PSG-1 against endothelial dysfunction may be related to activation of the PI3K/Akt/eNOS pathway.

    One of the most common and serious complications of diabetes mellitus is ulceration of the foot. Among persons with diabetes, 12%-25% will present to a healthcare institution for a foot disorder during their lifespan. Despite currently available medical and surgical treatments, these are still the most common diabetes-related cause of hospitalization and of lower extremity amputations. Thus, many adjunctive and complementary treatments have been developed in an attempt to improve outcomes. We herein review the available literature on the effectiveness of several treatments, including superficial and deep heaters, electro-therapy procedures, prophylactic methods, exercise and shoe modifications, on diabetic foot wounds. Overall, although physical therapy modalities seem to be useful in the treatment of diabetic foot wounds, further randomized clinical studies are required. PMID:25992328

    The purpose of this pilot study was to investigate type 2 diabetes risk among Asian Indians of Kerala ethnicity living in a West Texas County of the USA. The study used a descriptive correlational design with thirty-seven adult nondiabetic Asian Indian subjects between 20 and 70 years of age. The measurement included nonbiochemical indices of obesity, family history of type 2 diabetes, length of immigration in the US, history of hypertension, physical activity pattern, and fruit and vegetable intake. The majority of the subjects showed an increased nonbiochemical indices corresponding with overweight and obesity, placing them at risk for type 2 diabetes and associated cardiovascular complications. The physical activity pattern indicated a sedentary lifestyle. The decreased physical activity was associated with a higher Body Mass Index (BMI) and body fat percentage; length of residence in the US greater than 10 years was associated with increased body fat percentage and BMI; family history of type 2 diabetes was associated with an increase in body fat percentage. Fruit and vegetable intake pattern was not associated with a risk for type 2 diabetes. Further studies are recommended for risk surveillance among Asian Indian population living in the US.

    Backgrounds/Objective The prevalence of diabetes is increasing rapidly all over the world. However, studies on passive smoking and type 2 diabetes have not been systematically assessed. Therefore, we conducted a meta-analysis to explore whether an association exists between passive smoking and risk of type 2 diabetes. Methods We searched PubMed, EMBASE, Cochrane library and Web of Science up to April 9th, 2013, to identify prospective cohort studies that assessed passive smoking and risk of type 2 diabetes. The fixed-effect model was used to calculate the overall relative risk (RR). Result 4 prospective cohort studies were included for analysis, with a total of 112,351 participants involved. The pooled RR was 1.28 (95% confidence interval (CI) 1.14 to 1.44) comparing those who were exposed to passive smoking with those who were not. Subgroup, sensitivity analysis and publication bias test suggested the overall result of this analysis was robust. Conclusions Passive smoking is associated with a significantly increased risk of type 2 diabetes. Further well-designed studies are warranted to confirm this association. PMID:23922856

    Type 2 diabetes mellitus (T2DM) is a major global health problem. The present study examines the relationship between the metabolic, anthropometric and Finnish risk score (FINDRISC) among normal and pre-diabetic adults. Subjects (n = 1319, aged above 18 years) from the Qatari population were classified into two groups based on their hemoglobin A1c (HbA1c) measurements (non-diabetic A1c<5.6% and pre-diabetic 5.6% ≤ A1c ≤ 6.4%) were examined for their anthropometric (height, weight and waist circumference), metabolic [fat, fat free mass (FFM), muscle mass (MM), total body water (TBW), bone mass, degree of obesity, basal metabolic rate (BMR), body mass index (BMI), metabolic age, visceral fat rating, systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol (Total-C), low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglycerides (TG), fasting / random plasma glucose (FPG / RPG), HbA1c and vitamin D (VitD)] and FINDRISC. Means and frequencies were determined in aggregate and by subgroups for all variables and correlations between categorical variables were tested to estimate the association between the anthropometric and metabolic risk factors with the FINDRISC. A percentage of 74.8% (n = 987) of the study population aged below 45 years old and their overall BMI was 28.8±5.2kg/m2 (overweight). Pre-diabetic subgroup have shown a statistically higher FINDRISC compared to their non-diabetic counterparts (11.2±4.1 vs. 9.8±4, p<0.001). The FINDRISC was significantly and directly correlated with the BMI, HbA1c and FPG. However, HbA1c was correlated directly with BMI, SBP, DBP, FPG / RPG and indirectly with the levels of HDL. This study demonstrates an apparent relationship between the HbA1c and FINDRISC score. Pursuing further research on this association may permit using HbA1c with the FINDRISC in predicting the risk of T2DM to be a better tool rather than using the current FPG/RPG, OGTT methods.

    Previous studies have revealed that diabetic patients have a decline in immunity and an increased risk of infections, and this may be associated with poor micronutrient status. The aim of this study was to measure the effect of dietary supplements on risk of infection in patients with type 2 diabetes mellitus. One hundred patients with type 2 diabetes mellitus were randomly assigned to receive an oral dose of daily B-group vitamins and antioxidant vitamins (n = 50) or an identical placebo (n = 50) daily for 90 days. Patients had baseline, three and 12 month assessment for nutritional status, fruits and vegetables intake, physical activity and self-reported infections. Supplementation with antioxidants and B-group vitamins significantly increased the plasma concentration of vitamin E and folate and reduced homocysteine in the intervention group (p-values were 0.006, 0.001 and 0.657, respectively). The number of infections reported by the treatment group after three months of supplements was less than that reported by the placebo group, 9 (27%) vs. 15 (36%) (p = 0.623). Corresponding numbers of infections at 12 months were 25 (67.5%) and 27 (56.3%), respectively (p = 0.488). Up to 90% of the diabetic patients were either overweight or obese with a sedentary life style, and their body weight increased further during three months of follow up. The study showed that multivitamin supplements improved vitamin blood concentrations; however, this did not reduce the number of infections in diabetic patients. PMID:23462586

    Background and Aims. Diabetic neuropathy is a frequent complication of type 2 diabetes mellitus (T2DM). Genetic susceptibility and oxidative stress may play a role in the appearance of T2DM and diabetic neuropathy. We investigated the relation between polymorphism in genes related to oxidative stress such as GSTM1, GSTT1, and GSTP1 and the presence of T2DM and diabetic neuropathy (DN). Methods. Samples were collected from 84 patients with T2DM (42 patients with DN and 42 patients without DN) and 98 healthy controls and genotyped by using polymerase chain reaction and restriction fragment length polymorphism method. Results. GSTP1 Ile105Val polymorphism was associated with the risk of developing T2DM (p = 0.05) but not with the risk of developing DN in diabetic cases. GSTM1 and GSTT1 gene polymorphisms were associated with neither the risk of developing T2DM nor the risk of DN occurrence in diabetic patients. No association was observed between the patients with T2DM and DSPN (diabetic sensorimotor peripheral neuropathy) and T2DM without DSPN regarding investigated polymorphism. Conclusion. Our data suggest that GSTP1 gene polymorphisms may contribute to the development of T2DM in Romanian population. GSTM1, GSTT1, and GSTP1 gene polymorphisms are not associated with susceptibility of developing diabetic neuropathy in T2DM patients. PMID:26435566

    The effect of language acculturation, socioeconomic status (SES), and immigrant generation on development of diabetes among Mexican Americans was evaluated in the Hispanic Established Population for the Epidemiologic Study of the Elderly (HEPESE). HEPESE is a longitudinal cohort study of 3,050 non-institutionalized Mexican Americans aged 65 years at baseline (1993-1994) from 5 Southwestern states. Diabetes incidence was ascertained in 4 follow-up surveys to 2004-05 by respondent self-reported physician-diagnosis of diabetes, high blood glucose, or sugar in the urine. Language of interview, immigrant generation, gender, age, education, family history of diabetes, smoking status, alcohol use, health insurance type and self-reported height and weight were assessed. High socioeconomic status (SES) was defined by high school graduation and non-Medicaid insurance. Cox's proportional hazards models were fit to evaluate the effects of language acculturation, generation and SES on incident diabetes. 845 of 3,050 (27.7%) Mexican Americans had diabetes at baseline and were younger, more educated, and more likely to have health insurance than those without diabetes. Risk of developing diabetes increased for Spanish-speaking respondents with low SES from 1st to 3rd generation (HR = 1.76, 95% CI = 1.02-3.03) and from 2nd to 3rd generation (HR = 2.15, 95% CI = 1.20-3.84). Among English-speaking, high SES participants, generation had a protective effect on developing diabetes: HR = 0.45 (95% CI = 0.22-0.91) when comparing 3rd versus 1st generation. The effect of language acculturation and immigrant generation on incident diabetes is moderated by SES status in HEPESE participants.

    In this study, we investigate the effect of argan oil consumption on serum lipids, apolipoproteins (AI and B), CRP, and LDL susceptibility to oxidation in type 2 diabetic patients which are known to have a high level of cardiovascular risk due to lipid abnormalities and lipid peroxidation. For that, 86 type 2 diabetic patients with dyslipidemia were randomized to one group consuming 25 mL/day of argan oil during 3 weeks and control group consuming 20 g/day of butter in breakfast. After argan oil intervention, serum triglycerides decreased by 11.84%, (P = 0.001), total chol by 9.13%, (P = 0.01), and LDL-chol by 11.81%, (P = 0.02). However, HDL-chol and Apo AI increased (10.51%, P = 0.01 and 9.40%,  P = 0.045, resp.). Susceptibility of LDL to lipid peroxidation was significantly reduced by increasing of 20.95%, (P = 0.038) in lag phase after argan oil consumption. In conclusion, we show for the first time that consumption of argan oil may have an antiatherogenic effect by improving lipids, and the susceptibility of LDL to oxidation in type 2 diabetes patients with dyslipidemia, and can therefore be recommended in the nutritional management of type 2 diabetes.

    Type 2 diabetes, fuelled by the obesity epidemic, is an escalating worldwide cause of personal hardship and public cost. Diabetes incidence increases with age, and many studies link the classic senescence and ageing protein p16(INK4A) to diabetes pathophysiology via pancreatic islet biology. Genome-wide association studies (GWASs) have unequivocally linked the CDKN2A/B locus, which encodes p16 inhibitor of cyclin-dependent kinase (p16(INK4A)) and three other gene products, p14 alternate reading frame (p14(ARF)), p15(INK4B) and antisense non-coding RNA in the INK4 locus (ANRIL), with human diabetes risk. However, the mechanism by which the CDKN2A/B locus influences diabetes risk remains uncertain. Here, we weigh the evidence that CDKN2A/B polymorphisms impact metabolic health via islet biology vs effects in other tissues. Structured in a bedside-to-bench-to-bedside approach, we begin with a summary of the evidence that the CDKN2A/B locus impacts diabetes risk and a brief review of the basic biology of CDKN2A/B gene products. The main emphasis of this work is an in-depth look at the nuanced roles that CDKN2A/B gene products and related proteins play in the regulation of beta cell mass, proliferation and insulin secretory function, as well as roles in other metabolic tissues. We finish with a synthesis of basic biology and clinical observations, incorporating human physiology data. We conclude that it is likely that the CDKN2A/B locus influences diabetes risk through both islet and non-islet mechanisms. PMID:27155872

    OBJECTIVE Age at menopause is an important determinant of future health outcomes, but little is known about its relationship with type 2 diabetes. We examined the associations of menopausal age and reproductive life span (menopausal age minus menarcheal age) with diabetes risk. RESEARCH DESIGN AND METHODS Data were obtained from the InterAct study, a prospective case-cohort study nested within the European Prospective Investigation into Cancer and Nutrition. A total of 3,691 postmenopausal type 2 diabetic case subjects and 4,408 subcohort members were included in the analysis, with a median follow-up of 11 years. Prentice weighted Cox proportional hazards models were adjusted for age, known risk factors for diabetes, and reproductive factors, and effect modification by BMI, waist circumference, and smoking was studied. RESULTS Mean (SD) age of the subcohort was 59.2 (5.8) years. After multivariable adjustment, hazard ratios (HRs) of type 2 diabetes were 1.32 (95% CI 1.04–1.69), 1.09 (0.90–1.31), 0.97 (0.86–1.10), and 0.85 (0.70–1.03) for women with menopause at ages <40, 40–44, 45–49, and ≥55 years, respectively, relative to those with menopause at age 50–54 years. The HR per SD younger age at menopause was 1.08 (1.02–1.14). Similarly, a shorter reproductive life span was associated with a higher diabetes risk (HR per SD lower reproductive life span 1.06 [1.01–1.12]). No effect modification by BMI, waist circumference, or smoking was observed (P interaction all > 0.05). CONCLUSIONS Early menopause is associated with a greater risk of type 2 diabetes.

    Impaired skin wound healing is a major medical problem in diabetic subjects. Kinins exert a number of vascular and other actions limiting organ damage in ischaemia or diabetes, but their role in skin injury is unknown. We investigated, through pharmacological manipulation of bradykinin B1 and B2 receptors (B1R and B2R respectively), the role of kinins in wound healing in non-diabetic and diabetic mice. Using two mouse models of diabetes (streptozotocin-induced and db/db mice) and non-diabetic mice, we assessed the effect of kinin receptor activation or inhibition by subtype-selective pharmacological agonists (B1R and B2R) and antagonist (B2R) on healing of experimental skin wounds. We also studied effects of agonists and antagonist on keratinocytes and fibroblasts in vitro. Levels of Bdkrb1 (encoding B1R) and Bdkrb2 (encoding B2R) mRNAs increased 1-2-fold in healthy and wounded diabetic skin compared with in non-diabetic skin. Diabetes delayed wound healing. The B1R agonist had no effect on wound healing. In contrast, the B2R agonist impaired wound repair in both non-diabetic and diabetic mice, inducing skin disorganization and epidermis thickening. In vitro, B2R activation unbalanced fibroblast/keratinocyte proliferation and increased keratinocyte migration. These effects were abolished by co-administration of B2R antagonist. Interestingly, in the two mouse models of diabetes, the B2R antagonist administered alone normalized wound healing. This effect was associated with the induction of Ccl2 (encoding monocyte chemoattractant protein 1)/Tnf (encoding tumour necrosis factor α) mRNAs. Thus stimulation of kinin B2 receptor impairs skin wound healing in mice. B2R activation occurs in the diabetic skin and delays wound healing. B2R blockade improves skin wound healing in diabetic mice and is a potential therapeutic approach to diabetic ulcers. PMID:26443866

    AIM: To investigate if the effect of statins improving cardiovascular (CV) status of diabetics is drug-specific or class-dependent, and the underlying mechanisms involved. METHODS: We compared the results of daily administration over a four-week period of a low dose (10 mg/kg per day) of atorvastatin (AV), simvastatin (SV), and pravastatin (PV) on cardiac performance in diabetic rats. Echocardiographic variables were tested, as well as systolic blood pressure (SBP), acetylcholine (ACh)-induced relaxation, plasma cholesterol levels, and perivascular fibrosis. Malondialdehyde (MDA) and 4-hydroxyalkenal (4-HAE), and endothelial nitric oxide synthase (eNOS) and inducible nitric oxide synthase (iNOS) protein levels were also measured in cardiac and aortic homogenates. RESULTS: In untreated diabetic rats, cholesterol levels were higher than in control rats (CT; n = 8, P < 0.05), and the low dose of statins used did not modify these levels. In diabetic rats, SBP was higher than in CT, and was significantly reduced by all three statins (n = 10, P < 0.05). Echocardiographic parameters (EF, SV, and COI) were all lower in untreated diabetic rats than in CT (n = 10, P < 0.05). These CV parameters were equally improved by all three statins. The maximal relaxation (EMax) induced by ACh in aortic ring from diabetic rats was also improved. Moreover, this relaxation was abolished by 1 mmol/L NG-nitro-L-arginine methyl ester, suggesting the involvement of a NO-dependent mechanism. CONCLUSION: AV, SV, and PV are equally effective in improving CV performance in diabetic rats. All tree statins decreased media thickness, perivascular fibrosis, and both MDA and 4-HAE in the aortas of diabetic rats, without affecting eNOS and iNOS protein levels. The observed hemodynamic benefits are cholesterol-independent. These benefits appear to be secondary to the improved endothelial function, and to the reduced vascular tone and remodeling that result from decreased oxidative stress. PMID:26322162

    The prevalence of type 2 diabetes mellitus is rising rapidly in all developed countries, particularly in the growing population of persons >50 years of age. As a dangerous consequence, this is accompanied by a proportionate increase in the incidence of chronic renal disease. Evidence-based medicine has shown that tight blood glucose control can delay the onset and retard the progression of diabetic complications, and while it is a challenge to closely manage the complexity of diabetes, it is more difficult to effectively treat the multiple associated comorbidities that develop. Best practice guidelines support early intervention and aggressive treatment of hypertension, hyperglycaemia, proteinuria, hypercholesterolemia, and anaemia. To date, guideline-based management has been proven to be difficult. This article describes the concept of the IRIDIEM studies. The objective of these studies is to endorse and facilitate the use of current best practice guidelines for the management of frequent comorbid diseases and established risk factors in the treatment of type 2 diabetes associated with chronic kidney disease. Additionally, IRIDIEM will assess the impact of this improved disease management model on the progression of chronic kidney disease that can result from electronically prompting clinicians with evidence-based treatment advice.

    Objective: Positive family history is associated with increased type 2 diabetes (T2D) risk, and reflects both genetic and environmental risks. Several studies have suggested an excess maternal transmission of T2D, although the underlying mechanism is unknown. We aimed to examine the association between maternal diabetes and cardiometabolic risk in the offspring. Methods: Parental history of diabetes and clinical data including anthropometric traits, fasting plasma glucose and insulin (FPG, FPI), blood pressure and lipid profile were collected from 2581 unrelated Chinese offspring (2026 adolescents from a population-based school survey and 555 adults from a community-based health screening programme). A subset of subjects (n=834) underwent oral glucose tolerance test to measure the glucose and insulin concentrations at 0, 15, 30, 60 and 120 min for evaluation of the areas under the curve (AUC) of glucose and insulin at 0–120 min, homoeostasis model assessment of insulin resistance (HOMA-IR) and bell-cell function, insulinogenic index, insulin sensitivity index (ISI) and oral disposition index (DI). Results: A positive parental history of diabetes was associated with increased risk of obesity (odd ratios (OR) (95% confidence interval (CI))=1.48 (1.10–2.00)), central obesity (OR (95% CI)=1.67 (1.21–2.32)), higher FPI, HOMA-IR, 2-h insulin, AUC of glucose at 0–120 min, triglycerides, reduced ISI and DI. Compared with individuals without parental diabetes, offspring with diabetic mother had significantly increased risk of obesity (OR (95% CI)=1.59 (1.07–2.35)), central obesity (OR (95% CI)=1.88 (1.23–2.88)), higher glucose levels and BP, were more insulin resistant but also had impaired first-phase insulin response and worse lipid profile. However, paternal history of diabetes had no effect on any of the studied traits, except higher body mass index, waist circumference in females and FPG. Conclusions: Our findings suggested that maternal history of

    Purpose of Review: This article provides an overview for understanding the diagnosis, pathogenesis, and management of diabetic neuropathy. Recent Findings: New information about the pathogenesis of diabetic neuropathy continues to emerge, which will lead to identifying new drug targets. It is clear that the natural history of diabetic neuropathy is changing and the rate of progression is slowing. This is likely because of a combination of earlier diagnosis, improved glycemic management, and improved control of related complications such as hyperlipidemia and hypertension. Early diagnosis is critical, and small fiber neuropathy or subclinical diabetic neuropathy may be reversed or significantly improved with appropriate intervention. The American Academy of Neurology recently published guidelines for the treatment of painful diabetic neuropathy. Summary: Diabetic neuropathy is common and can present with varied clinical presentations discussed in this article. Although treatment currently focuses on pain management, attention should be paid to potential risk factors for neuropathy. For example, glycemic control, hyperlipidemia, and hypertension should be managed with diet, exercise, and medications. Class I or II clinical studies indicate that pregabalin, duloxetine, amitriptyline, gabapentin, and opioids are effective in the management of diabetic neuropathic pain. PMID:25299279

    Conventional stroke risk prediction tools used in atrial fibrillation (AF) incorporate the presence of diabetes mellitus (DM) as a risk factor. However, it is unknown whether this risk is homogenous or dependent on the presence of diabetic microvascular complications, such as diabetic retinopathy, nephropathy, and neuropathy. The present study examined the risk of ischemic stroke in diabetic patients with and without microvascular complications. The present study used the National Health Insurance Research Database in Taiwan with detailed healthcare data on all-comers to the Taiwanese medical system from January 1, 1996 to December 31, 2011. AF and DM were identified when listed as discharge diagnoses or confirmed more than twice in the outpatient department. Patients on antithrombotic agents were excluded. The clinical endpoint was ischemic stroke. Among the 50,180 AF patients with DM, the majority had no microvascular complications (72.7%), while 2.6% had diabetic retinopathy, 8.4% had diabetic nephropathy, and 16.1% had diabetic neuropathy. Ischemic stroke occurred in 6003 patients, with a 4.74% annual risk of ischemic stroke. When compared with DM patients without microvascular complications, those with diabetic retinopathy, nephropathy, or neuropathy had higher incidences of ischemic stroke (4.65 vs 5.07, 4.77, or 5.20 per 100 person-years, respectively). However, after adjusting for confounding factors, the differences were no longer significant. In a large nationwide AF cohort with DM, risk of ischemic stroke was similar between patients with and without microvascular complications, suggesting that risk stratification of these patients does not require inclusion of diabetic retinopathy, nephropathy, and neuropathy.

    Clinical trials have demonstrated that it is possible to prevent diabetes through lifestyle modification, pharmacological intervention, and surgery. This review aims to summarize the effectiveness of these various therapeutic interventions in reducing the risk of progression of prediabetes to diabetes, and address the challenges to implement a diabetes prevention program at a community level. Strategies focusing on intensive lifestyle changes are not only efficient but cost-effective and/or cost-saving. Indeed, lifestyle intervention in people at high risk for type 2 diabetes mellitus (T2DM) has been successful in achieving sustained behavioral changes and a reduction in diabetes incidence even after the counseling is stopped. Although prediabetes is associated with health and economic burdens, it has not been adequately addressed by interventions or regulatory agencies in terms of prevention or disease management. Lifestyle intervention strategies to prevent T2DM should be distinct for different populations around the globe and should emphasize sex, age, ethnicity, and cultural and geographical considerations to be feasible and to promote better compliance. The translation of diabetes prevention research at a population level, especially finding the most effective methods of preventing T2DM in various societies and cultural settings remains challenging, but must be accomplished to stop this worldwide epidemic.

    Although the association between serum uric acid (SUA) levels and prehypertension has been reported in previous studies, it is unknown whether their relationship is similar in subjects with diabetes, pre-diabetes and normal glucose tolerance (NGT). This study thus aimed to investigate the relationship between SUA and prehypertension in subjects with different glycemic status, including NGT, pre-diabetes and diabetes. A total of 12 010 participants were included after excluding subjects with blood pressure ⩾140/90 mm Hg, history of hypertension, leukaemia, lymphoma, hypothyroidism, medication for hypertension and hyperuricemia and missing data. Subjects were divided into four groups based on SUA quartiles (male Q1: ⩽345.0, Q2: 345.0-392.6, Q3: 392.6-440.2, Q4: ⩾440.2 μmol l(-1) and female Q1: ⩽249.8, Q2: 249.8-285.5, Q3: 285.5-333.1, Q4: ⩾333.1 μmol l(-1)). Diabetes, pre-diabetes and NGT were assessed according to the 2010 American Diabetes Association diagnostic criteria. Normotension and prehypertension were defined according to the JNC-7 (The Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure) criteria. The SUA was significantly higher in prehypertensive subjects as compared with normotensive subjects. SUA, as a continuous variable, was positively associated with prehypertension in subjects with NGT but not pre-diabetes and diabetes. Besides, NGT subjects with the highest quartile of SUA exhibited a higher risk of prehypertension after adjustment for other confounding factors. In pre-diabetes and diabetes groups, none of SUA quartiles was significantly related to prehypertension. SUA was significantly associated with an increased risk of prehypertension in subjects with NGT but insignificantly in subjects with pre-diabetes and diabetes. PMID:26911534

  3. Academic Detailing in Diabetes: Using Outreach Education to Improve the Quality of Care.

    Most diabetes care is provided in primary care settings, but typical primary care clinicians struggle to keep up with the latest evidence on diabetes screening, pharmacotherapy, and monitoring. Accordingly, many patients with diabetes are not receiving optimal guideline-based therapy. Relying on front-line clinicians on their own to assess the huge volume of new literature and incorporate it into their practice is unrealistic, and conventional continuing medical education has not proven adequate to address gaps in care. Academic detailing, direct educational outreach to clinicians that uses social marketing techniques to provide specific evidence-based recommendations, has been proven in clinical trials to improve the quality of care for a range of conditions. By directly engaging with clinicians to assess their needs, identify areas for change in practice, and provide them with specific tools to implement these changes, academic detailing can serve as a tool to improve care processes and outcomes for patients with diabetes.

    Aims/Hypothesis To investigate secular trends in cardiovascular disease (CVD) risk factors during a decade of follow-up in a Middle Eastern cohort, and to compare observed trends between diabetic and non-diabetic populations. Methods In a population of 6181 participants (2622 males and 3559 females), diabetes status and CVD risk factors were evaluated in 4 study phases from 1999–2011. 1045 subjects had type 2 diabetes mellitus at baseline and 5136 participants were diabetes-free. To examine the trends of CVD risk factors, generalized estimation equation models were constructed. The interaction between the diabetes status and each phase of the study was checked in a separate model. Results During the follow-up period diabetic females significantly gained better control of their blood pressure, serum low density lipoprotein cholesterol and general and central obesity measures compared to non-diabetic counterparts, although 60% of them had high BP and 64% had high serum LDL-C levels till the end of the study. Diabetic males however, experienced significantly better control on their serum LDL-C and general and central obesity measures compared to their non-diabetic controls; but 24% of them were still smoker, 63% had high BP and 60% had high serum LDL-C levels at the end of the follow-up (all Ps interaction <0.05). Use of lipid-lowering and antihypertensive medications increased consistently in both diabetic and non-diabetic populations. Conclusions/Interpretation Although CVD risk factors have been controlled to some extent among diabetic population in Iran, still high numbers of people with diabetes have uncontrolled CVD risk factors that prompt more attention.

    This literature review aimed to explore previous knowledge about specific care requirements for persons with psychotic disorders and risk of or existing type 2 diabetes. Sixteen qualitative and quantitative studies in the area were identified and summarized. The studies together indicate that mental health nurses play an important role in motivating people to perform diabetes care as they are often known to and trusted by the patients. A holistic approach to the person's health, with close follow-ups by psychiatric care and cooperation with diabetes care, may have benefits for the person with diabetes. Screening for and treating psychotic symptoms is an important task for the mental health nurse, as these symptoms drain energy from the person and prevent diabetes self-care. Lifestyle and diabetes education needs to be practical, adapted to the individual and focused on maintaining a healthy diet, regular exercise, changing smoking habits and preventing diabetes complications. Treatment with antipsychotic drugs increases the need for follow-ups of glycaemic control.

    The earliest clinical evidence of diabetic nephropathy is microalbuminuria. Progression from microalbuminuria to overt nephropathy occurs in 20-40% within a 10-year period with approximately 20% of these patients progressing to end-stage renal disease. End-stage renal disease develops in 50% of type-1 diabetes patients with overt nephropathy within 10 years and in more than 75% by 20 years in the absence of treatment. In type-2 diabetes, a greater proportion of patients have microalbuminuria and overt nephropathy at or shortly after diagnosis of diabetes. The incidence of diabetes is increasing worldwide, with subsequent increase in the incidence of diabetic nephropathy. The risk factors identified in the development of DN from longitudinal and cross-sectional studies include race, genetic susceptibility, hypertension, hyperglycemia, hyperfiltration, smoking, advanced age, male sex, and high-protein diet. Treatment interventions in diabetic nephropathy include glycemic control, treatment of hypertension, hyperlipidemia, cessation of smoking, protein restriction, and renal replacement therapy. Multifactorial approach includes combined therapy targeting hyperglycemia, hypertension, microalbuminuria, and dyslipidemia. PMID:15586648

    OBJECTIVE: To examine whether a family history of high-risk groups for major noncommunicable diseases (NCDs) was a significant risk factor for these conditions among family members in a study population in the Gambia, where strong community and family coherence are important determinants that have to be taken into consideration in promoting lifestyle changes. METHODS: We questioned 5389 adults as to any first-degree family history of major noncommunicable diseases (hypertension, obesity, diabetes and stroke), and measured their blood pressure (BP) and body mass index (BMI). Total blood cholesterol, triglyceride, uric acid, and creatinine concentrations were measured in a stratified subsample, as well as blood glucose (2 hours after ingesting 75 g glucose) in persons aged > or = 35 years. FINDINGS: A significant number of subjects reported a family history of hypertension (8.0%), obesity (5.4%), diabetes (3.3%) and stroke (1.4%), with 14.6% of participants reporting any of these NCDs. Subjects with a family history of hypertension had a higher diastolic BP and BMI, higher cholesterol and uric acid concentrations, and an increased risk of obesity. Those with a family history of obesity had a higher BMI and were at increased risk of obesity. Individuals with a family history of diabetes had a higher BMI and higher concentrations of glucose, cholesterol, triglycerides and uric acid, and their risk of obesity and diabetes was increased. Subjects with a family history of stroke had a higher BMI, as well as higher cholesterol, triglyceride and uric acid concentrations. CONCLUSIONS: A family history of hypertension, obesity, diabetes, or stroke was a significant risk factor for obesity and hyperlipidaemia. With increase of age, more pathological manifestations can develop in this high-risk group. Health professionals should therefore utilize every opportunity to include direct family members in health education. PMID:11357211

  12. Understanding the type 2 diabetes mellitus and cardiovascular disease risk paradox.

    Green, Jennifer B

    2014-05-01

    Patients with diabetes have approximately a 2-fold increase in the risk for coronary heart disease, stroke, and death from vascular causes compared with patients who do not have diabetes. Interventions targeted at modifiable risk factors, such as smoking cessation and management of hypertension and dyslipidemia, reduce the risk of cardiovascular disease (CVD) in patients with type 2 diabetes mellitus (T2DM). Paradoxically, large randomized studies have failed to conclusively show that intensively lowering glucose reduces CVD event rates in patients with T2DM, despite pathophysiologic and epidemiologic evidence suggesting that hyperglycemia contributes to CVD. Although initiation of intensive glycemic control early in the disease course may be associated with a reduction in the long-term risk of cardiovascular (CV) events, this approach in those with long-standing or complicated T2DM is not of clear benefit and may even be harmful in some. Failure to mitigate risk with antihyperglycemic therapy and the potential for some treatments to increase CVD risk underlies a treatment paradox. New glucose-lowering therapies are now subject to close scrutiny for CV safety before and after drug approval. Results from the first trials designed to meet the recent CV regulatory requirements have shown no increased risk of major adverse CV events but also no CV benefit from dipeptidyl peptidase-4 inhibitor therapy, as well as a potentially increased risk of hospitalization for heart failure. Conclusive evidence of CV risk reduction with glucose-lowering therapy is still lacking and scrutiny of additional agents is necessary. Type 2 diabetes mellitus is a heterogeneous disease, for which patient-centered, individualized care, and goal-setting is appropriate. Interventions that focus on the management of CV risk factors and glucose lowering with medications that are not cardiotoxic represent an optimal and attainable treatment approach.

    Gestational diabetes mellitus is a condition commonly encountered during mid to late pregnancy with pathologic manifestations including hyperglycemia, hyperinsulinemia, insulin resistance, and fetal maldevelopment. The cause of gestational diabetes mellitus can be attributed to both genetic and environmental factors, hence complicating its diagnosis and treatment. Pancreatic progenitors derived from human embryonic stem cells were shown to be able to effectively treat diabetes in mice. In this study, we have developed a
