Telomere dynamics in arteries and mononuclear cells of diabetic patients: effect of diabetes and of glycemic control

Telomeres serve as a mitotic clock and biological marker of senescence. Diabetes mellitus (DM) is associated with damage to target organs and premature aging. We assessed the effect of glycemic control on telomere dynamics in arterial cells of 58 patients undergoing coronary artery bypass and in mononuclear blood cells of other diabetic (32 type I and 47 type II) patients comparing well controlled to uncontrolled patients. All were compared to age-dependent curve of healthy controls. Telomeres were significantly shorter in the arteries of diabetic versus non-diabetic patients (p=0.049) and in mononuclear cells of both type I and type II diabetes. In all study groups good glycemic control attenuated shortening of the telomeres. In arterial cells good glycemic control attenuated, but not abolished, the telomere shortening. In type II DM the mononuclear telomere attrition was completely prevented by adequate glycemic control. Telomere shortening in mononuclear cells of type I diabetic patients was attenuated but not prevented by good glycemic control. Results of this study suggest that diabetes is associated with premature cellular senescence which can be prevented by good glycemic control in type II DM and reduced in type I DM.     

Pharmacological treatment of type 2 diabetes in Saudi Arabia: A consensus statement from the Saudi Society of Endocrinology and Metabolism (SSEM)

Background and aimsThe list of available treatment options for managing blood glucose in patients with type 2 diabetes (T2D) has grown over recent years making the task of choosing between traditional and newer glucose-lowering agents a difficult one for healthcare providers.MethodsWe summarize treatment algorithms developed by popular professional societies and propose a patient-centered and culture-driven recommendations for selecting diabetes medications for people with T2D in Saudi Arabia.ResultsThough most professional societies recognize patient’s adherence to medications as an important factor in achieving glycemic targets, published algorithms schemes do not formally enlist adherence to medication as a deciding factor in the choice of glucose-lowering agents. Medication appeal to patients, an important determinant of medication adherence, is influenced by several factors including lifestyle, common beliefs, customs and traditions, health literacy, perception of health and disease, socioeconomic and cultural backgrounds, and religious commitments and obligations. In Saudi Arabia, poor adherence to therapy is a major obstacle to effective management of local people with T2D.ConclusionsThe Saudi population has a unique socioeconomic and cultural background that widely respect adherence to religion and culture; and the applicability of international guidelines for the management of T2D to the Saudi population has been called into question. In this consensus statement, we propose patient-centered and culture-driven recommendations that integrate medication-adherence and medication-cost into overall selection of diabetes medications for people with T2D in Saudi Arabia.

Association between early glycemic management and diabetes complications in type 1 diabetes mellitus: A retrospective cohort study

AimsTo investigate the association between early HbA1c levels near diagnosis and future glycemic management, and analyzed risk factors of complications in people with T1DM.MethodsThis retrospective cohort study included 201 children and adolescents with T1DM. Patient data including sex, age at diagnosis, duration of disease, HbA1c levels, HbA1c variability during the follow-up period, and diabetes complications and comorbidities were collected.ResultsThe mean follow-up period of patients was 16.4 years. HbA1c levels in all three examined time points after diagnosis (first year, second year, and first two years) were significantly associated with recent HbA1c level, and second-year HbA1c was most closely correlated with recent HbA1c level. Elevated second-year HbA1c was a risk factor of diabetic ketoacidosis (DKA) and retinopathy, and increased variability of HbA1c was significantly related to various microvascular complications. When HbA1c is stratified into quartiles, the subjects of each quartile trend to stay within that quartile over the follow-up period.ConclusionsEarly HbA1c levels were closely associated with recent HbA1c levels and diabetes complications in patients with T1DMs. Strict glucose management after diagnosis and reducing variability of HbA1c may prevent future diabetes complications and comorbidities.     

Effects of a health education program to promote healthy lifestyle and glycemic control in patients with type 2 diabetes: A randomized controlled trial

BackgroundType 2 diabetes mellitus (T2DM) is a common chronic disease with an increase in prevalence within developing countries. The aim of this study was to determine the efficacy of a structured educational program for improving lifestyle and health-related measures in Iranians with T2DM.MethodsA randomized controlled trial was conducted in 80 participants with T2DM who were randomly assigned to either the intervention or a control group. A demographic questionnaire along with the Health Promoting Lifestyle Profile-II and related laboratory tests were used to assess the efficacy of the program. The intervention consisted of six educational sessions held over 45 days. The control group received routine diabetic care at the clinic. Three months after the intervention, participants completed the measures again. Within-group and between-group comparisons were then made.ResultsAll subscales of lifestyle measure improved in the intervention group, whereas only the nutrition domain improved in the control group. After adjusting for baseline differences, physical activity and nutrition domains showed the greatest improvement in the intervention group compared to controls. All clinical measures were also significantly improved within intervention group from baseline to follow-up (p < 0.001), whereas HbA1c, fasting blood glucose, HDL, triglyceride, cholesterol, and weight also changed significantly in the control group. The frequency of HbA1c < 7% was increased from 27.5% at baseline to 37.5% at follow-up (10%) in the intervention group compared to only a 5% increase in the control group.ConclusionThis educational health program significantly improved lifestyle changes and health-related clinical characteristics in persons with T2DM, compared to routine diabetic care in Iran. Further research is needed to better understand the usefulness of such programs in diabetics and other medical conditions among those in different cultural settings.     

Efficacy of i-Port Advance system on patients satisfaction and glycemic control among patients with type 1 diabetes in Saudi Arabia

Background and aimsTo determine the efficacy of i-Port Advance system on patients satisfaction and glycemic control among patients with type 1 diabetes (T1D).MethodsThis prospective study was performed among 73 patients with T1D (13–29 years) at Prince Sultan Military Medical City, Riyadh, Saudi Arabia. Demographic data were collected at baseline and clinical characteristics were collected at baseline and 12 weeks. Patients’ responses to Morisky Medication Adherence Scale (MMAS-8) and Insulin Delivery Satisfaction Survey (IDSS) were recorded at baseline and 12 weeks after initiating the i-Port Advance system.ResultsAt 12 weeks, significant improvement was evident in the IDSS subscales, which comprises the IDSS effective (p = 0.048), burdensome (p = 0.032), and IDSS inconvenient (p = 0.001), with the total baseline IDSS score being 2.6 ± 0.42, and at 12 weeks being 3.7 ± 0.72 (p = 0.037). The MMAS total score at baseline was 4.6 ± 1.2, and at 12 weeks, it increased to 6.4 (p = 0.028). HbA1c level was 8.4% at baseline and decreased to 7.9% (p = 0.001) at 12 weeks. The total daily dose of insulin at baseline registered 0.9 ± 0.13, which declined to 0.8 ± 0.12 (p = 0.048) at 12 weeks. Fasting blood sugar value was 197 ± 23.4 at baseline, which dropped to 182 ± 24.5 at 12 weeks (p = 0.01); and the postprandial glucose at baseline was 195 ± 21.4 and declined to 177 ± 19.2 at 12 weeks (p = 0.01). The hypoglycemic episodes revealed a noteworthy reduction after the i-Port Advance system usage.ConclusionUse of i-Port Advance system was found to raise the patients’ satisfaction levels and lower both the hypoglycemic episodes as well as the HbA1c levels.     

Impact of adherence to Mediterranean diet and/or drug treatment on glycaemic control in type 2 diabetes mellitus patients: DM2-CUMCYL study

AimsThis study aimed to analyse the association between adherence to treatment and glycaemic control in people with type 2 diabetes mellitus.MethodsMulticentre, cross-sectional study in patients with type 2 diabetes mellitus recruited by primary care professionals in Castilla y León (Spain). Sociodemographic and clinical characteristics were reflected in self-reported questionnaire, which included the Morisky-Green Medication Adherence Scale and the 14-point Mediterranean Diet Adherence Screener. Medication non-adherence and poor glycaemic control were analysed by bivariable and multivariable analyses.ResultsOf 3536 included patients, the 33.8% reported non-adherence to pharmacological treatment, and the 33.7% had poor glycaemic control (HbA1c ≥58 mmol/mol [7.5%]); 50.6% of patients reported moderate-high adherence to the Mediterranean diet (≥9 points). The multivariable logistic regression model showed that educational level (OR 0.73; 95% CI 0.61-0.87; p < 0.001) and sedentarism (OR 1.64; 95% CI 1.36−1.98; p < 0.001) were associate with low adherence. Younger age, rural residence, smoking, time since diagnosis (OR 1.04; 95% CI 1.03−1.05; p < 0.001) and polypharmacy were associated with poor glycaemic control.ConclusionLower educational level and sedentarism were associated with low adherence. Younger age, rural residence, smoking, time since diagnosis and polypharmacy, increased risk of poor glycaemic control.     

Species distribution and influence of glycemic control on fungal infections in pregnant women with diabetes

Objectives. (1) To find the distribution of species among fungal strains isolated from pregnant women with diabetes mellitus (DM), gestational diabetes (GDM) and healthy controls (CON); (2) to analyse the influence of glycemia on the prevalence of fungi in different body sites.Methods. Mycological examinations were performed in 251 pregnant women: 119 diabetic (47 DM, and 72 GDM) and 132 controls. Samples were collected from vagina, rectum and oral cavity of all women and cultured on Sabouraud media.Results. A total of 212 fungal strains were isolated, 12 fungal species were identified: 89.6% of the strains belonged to Candida gender, 10.4% to Saccharomyces, Geotrichum, Rhodotorula and Trichosporon genera. The prevalence of fungi, respectively, in vagina and rectum, was significantly higher in diabetics with poor glycemic control when stratified (<100 mg/dl, 100–120 mg/dl and >120 mg/dl) both the mean week glucose levels (MWGL) levels (p=0.03, p=0.03) and glycemia 90 min after breakfast (p=0.04, 0.03). No difference was found in the prevalence of fungi and glycolised hemoglobin (HbA1).Conclusions. MWGL showed an association between glycemia and prevalence of fungi. However, no relation was found between HbA1 and fungal infections in well controlled diabetic pregnancies.     

The effect of periodontal therapy on the improvement of glycemic control in patients with type 2 diabetes mellitus: A randomized controlled clinical trial

AIMS:

The purpose of this study is to investigate the effect of improved periodontal health on glycemic control in type 2 diabetes mellitus (type 2 DM) patients who have generalized periodontitis.

MATERIALS AND METHODS:

A total of 45 type 2 DM patients with generalized periodontitis were selected for the study. The selected patients were randomly assigned to three groups (groups A, B, and C) comprising 15 patients each: • Group A received treatment with scaling and root planing only. • Group B received treatment with scaling and root planing followed by systemic doxycycline. • Group C received no treatment (control group). The periodontal parameters recorded included plaque index, gingival index, probing pocket depth, and clinical attachment level. These parameters were recorded at baseline (day zero), at 1 month, and at the end of 3 months. The following metabolic parameters were recorded: fasting blood glucose (FBG), postprandial blood glucose (PPBG), and glycated hemoglobin. These were recorded at baseline (day zero) and at the end of 3 months.

STATISTICAL ANALYSIS:

All the parameters were subjected to repeated-measures ANOVA and Scheffe''s post hoc test.

RESULTS:

A statistically significant effect could be demonstrated for periodontal parameters for both group A and group B (treatment groups). Glycated hemoglobin values showed statistically significant decrease in treatment groups compared to the control group, with group B showing more significant decrease than group A.

CONCLUSIONS:

The results of this study showed that nonsurgical periodontal treatment is associated with improved glycemic control in type 2 DM patients.

Abstract：

Objective To investigate the current status of type 2 diabetic patients who failed to achieve the glycemic control target, and provide theoretic evidences for making corresponding strategies. Methods The 2 diabetic patients who failed to reach the glycemic target were recruited from 181 hospitals in 26 cities and received a standard questionnaire, the conditions of their blood glucose level, lifestyle intervention, blood sugar monitoring, and drug therapy were recorded. Totally 3 861 questionnaires with complete information were collected. And the causes which account for glycemic control status were analyzed. Results Among these patients, the mean HbA1c was 7.9%, the mean fasting plasma glucose was 8.2 mmol/L, and the mean postprandial plasma glucose was 11.5 mmol/L. Only 25.6% of patients take their diet control strictly as prescribed and 44. 5% of patients have little exercise. 35. 8% and 47.8% of patients did not monitor their fasting and postprandial plasma glucose,respectively. Glycemic control in the patients aged ＞ 60 years was similar to the younger patients, but the hypoglycemia incidence in the elder group reached 35.5%, which was higher than those in the other 2 groups (20.8% and 21.4%, both P＜0. 05 ). The proportion of patients with mono-therapy and combination therapy was 46. 1% and 51.7%, while the proportion with combination therapy rose in the patients aged ＞60 years (58.7%;Compared with the other age-groups, all P＜0.05 ). 75 % of patients have adjusted their drug administration regimen since initial treatment. Conclusions Inadequate or inappropriate drug therapy regimen is a major cause responsible for this poor glycemic control status. In addition, the unhealthy life styles, insufficient blood sugar monitoring, and poor compliance were also important causes. Thus, for these patients, it is necessary to further enhance patients' education, to improve life style intervention, as well as to select more effective, safer, and compliant drug therapy regimens. Finally, the glycemic control target for the elder patients should be more flexible.     

Impact of the FreeStyle Libre flash glucose monitoring system on diabetes- self-management practices and glycemic control among patients with type 2 diabetes in Saudi Arabia: A prospective study

Background and aimsTo examine the efficacy of FreeStyle Libre Flash Glucose Monitoring System (FGMS) on Diabetes Self-Management Practices (DSMP) and glycemic control among patients with type 2 diabetes (T2D).MethodsThis prospective study was conducted among 105 patients with T2D (aged 30–70 years), who self-tested their glucose levels by conventional finger-prick method using blood glucose meters (BGM). At baseline visit, FGMS sensors were fixed by a diabetes educator to all patients. At the baseline and at 12 weeks of the study, an interviewer collected the responses of Diabetes Self-Management (DSM) from all the study population using a questionnaire.ResultsAt 12 weeks, significant improvements in the DSM subscales were observed, which includes glucose management (P = 0.042), dietary control (P = 0.048), physical activity (P = 0.043), health care use (P = 0.001) and self-care (P = 0.001), compared to the values at baseline. At baseline, when the HbA1c level was 8.2%, at 12 weeks, it dropped to 7.9%. Also, at baseline, when the hypoglycemia frequency was 3.1, it declined to 1.2 episodes/month at 12 weeks. While comparing the blood glucose monitoring through BGM at the baseline (1.92/day), a higher degree of frequency of blood glucose monitoring was evident at 12 weeks (6.84/day), after the patients employed the FreeStyle Libre.ConclusionAfter 12 weeks of using the FreeStyle Libre, the frequency of hypoglycemic episodes and the HbA1c levels were dropped, while the practice of DSM and frequency of blood glucose monitoring were improved.     

Association of community-level food insecurity and glycemic control among pregnant individuals with pregestational diabetes

AimTo evaluate whether pregnant individuals with pregestational diabetes who live in a food-insecure community have worse glycemic control compared to those who do not live in a food-insecure community.MethodsA retrospective analysis of pregnant individuals with pregestational diabetes enrolled in a multidisciplinary prenatal and diabetes care program. The exposure was community-level food insecurity per the Food Access Research Atlas. The outcomes were hemoglobin A1c (A1c) < 6.0 % in early and late pregnancy, and an absolute decrease in A1c ≥ 2.0 % and mean change in A1c across pregnancy.ResultsAmong 418 assessed pregnant individuals with pregestational diabetes, those living in a food-insecure community were less likely to have an A1c < 6.0 % in early pregnancy compared to those living in a community without food insecurity [16 % vs. 30 %; adjusted risk ratio (aRR): 0.55; 95 % CI: 0.33–0.92]. Individuals living in a food-insecure community were more likely to achieve a decrease in A1c ≥ 2.0 % [35 % vs. 21 %; aRR: 1.55; 95 % CI: 1.06–2.28] and a larger mean decrease in A1c across pregnancy [mean: 1.46 vs. 1.00; adjusted beta: 0.47; 95 % CI: 0.06–0.87)].ConclusionsPregnant individuals with pregestational diabetes who lived in a food-insecure community were less likely to enter pregnancy with glycemic control, but were more likely to have a reduction in A1c and achieve similar A1c status compared to those who lived in a community without food insecurity. Whether interventions that address food insecurity improve glycemic control and consequent perinatal outcomes remains to be studied.     

Design of the cooperative study on glycemic control and complications in diabetes mellitus type 2: Veterans Affairs Diabetes Trial

INTRODUCTION: Long-term glycemic control trials in type 2 diabetes show as the main clinical benefit a difference in retinal photocoagulation (3/1000 in the UK Prospective Diabetes Study [UKPDS]), but no effect on visual acuity or renal failure. No intensive glycemic control trial has yet affected cardiovascular (CV) events, the main cause of morbidity and mortality. By contrast, modest blood pressure reduction has protective effects on visual acuity, renal function, CV events, and mortality. Optimal glycemic control goals are not established in elderly, obese persons with advanced complications, the most common patients in the Veterans Affairs (VA) system. The earlier feasibility trial in such patients (VA-CSDM) suggested potentially worse CV outcomes with lower attained hemoglobin A1c (HbA1c) levels. OBJECTIVES: The primary objective of the Veterans Affairs Diabetes Trial (VADT) is the assessment of the effect of intensive glycemic treatment on CV events. Other objectives are effects on microangiopathy, quality of life, and cost effectiveness. RESEARCH DESIGN AND METHODS: The VADT, started in December 2000, is enrolling 1700 men and women previously uncontrolled on insulin or maximum doses of oral agents at 20 VA medical centers. Accrual is 2 years and follow-up is 5-7 years, with visits every 1.5 months. The study has a power of 86% to detect a 21% relative reduction in major CV events (CV death, myocardial infarction [MI], cerebrovascular accident [CVA], congestive heart failure [CHF], revascularization and amputation for ischemia). Subjects are randomized to an intensive arm aiming at normal HbA1c levels or to a standard arm with usual, improved glycemic control. An HbA1c separation of >1.5% is to be maintained (expected 2%). Both arms receive step therapy: glimepiride or metformin plus rosiglitazone and addition of insulin or other oral agents to achieve goals. Strict control of blood pressure and dyslipidemia, daily aspirin, diet, and education are identical in both arms. Plasma fibrinogen, plasminogen-activating inhibitor I (PAI-I), lipids, renal function parameters, and ECG are measured throughout. Stereo retinal photographs are obtained at entry and 5 years, eye examinations yearly, and intervention as needed to prevent visual deterioration. Recruitment is proceeding on schedule: the current mean HbA1c at entry is 9.4+/-1.6% and mean duration of diagnosed diabetes 11+/-8 years.     

A study on the glycemic,lipid and blood pressure control among the type 2 diabetes patients of north Kerala,India

AimThe aim of the study was to detect the level of comprehensive diabetes control among the diabetic patients of Kerala, India.MethodsPatients (1200) were randomly selected from a diabetes care center. Their blood sugar, biochemical and anthropometric measurements were done and statistically analyzed.ResultsOnly 28.3% had their HbA1c at or below 7% and 45% above 9%. One-third of the female and one-fifth of the male patients had coronary artery disease. The prevalence of hypertension was almost equal in both sexes. However, there was a statistically significant higher systolic blood pressure (mean 162.12 mmHg vs 147.49 mmHg, p = 0.01044) among females. The total cholesterol was above 200 mg/dl in 42.1% of males and 45.61% of females. The triglyceride was >150 mg/dl in 38.6% males and 50.88% females. Low high density lipoprotein (HDL) cholesterol levels were found in 20.07% of males and 41.12% of females (p = 0.0445). The mean low density lipoprotein (LDL) was 121.75 (± 32.29)ConclusionThe mean blood sugar values are found to be high, which will lead to a predictable increase in vascular disease, which in turn will affect the quality of health and productivity of the individual and the economic growth of the society as a whole. Studies suggest that therapeutic interventions to improve glycemic control may reduce the risk of cardiovascular disease and microvascular disease.This study shows that the level of diabetes control in Kerala is unsatisfactory. We need more medications, better strategies and more emphasis on glycemic management than we are currently able to apply.     

Food insecurity and glycemic control in individuals with diagnosed and undiagnosed diabetes in the United States

AimsInvestigate the relationship between food insecurity and glycemic control in adults with diagnosed and undiagnosed diabetes.MethodsUsing National Health and Nutrition Examination Survey (NHANES) between 2003–2016, food insecurity was measured using the household food insecurity scale. Glycemic control was measured using glycated hemoglobin (HbA1c) collected during the NHANES examination. Individuals were categorized into undiagnosed diabetes or diagnosed diabetes based on their measured HbA1c and response to whether they were told by a doctor or other health professional they have diabetes or were taking medications for diabetes. Sampling weights and survey procedures were used when conducting univariate and multivariable models using SAS version 9.4.ResultsApproximately 13.7% of the population sample (35,216 adults representing 207,271,917 US adults) reported food insecurity. Reporting food insecurity was associated with 0.37 higher HbA1c for diagnosed (95% CI 0.15−0.60) and 0.45 higher HbA1c for undiagnosed diabetes (95% CI 0.05−0.85). In the undiagnosed diabetes population, those reporting food insecurity had 80% higher likelihood of HbA1c above 7% (OR = 1.80, 95% CI 1.06–3.06).ConclusionsFood insecurity had a stronger relationship with HbA1c for those with undiagnosed diabetes. Results suggest the importance of screening for individuals with food insecurity that may be at high risk for having undiagnosed diabetes.     

The associations between physical activity,health-related quality of life,regimen adherence,and glycemic control in adolescents with type 1 diabetes: A cross-sectional study

BackgroundAdolescents with Type 1 Diabetes (T1D) display a greater than two-fold higher risk of developing diabetes-related complications compared with their healthy peers and the risk increases markedly as glycated hemoglobin (HbA1c) increases. The majority of the known factors associated with improved glycemic control in adolescents with T1D are geared toward Western populations. Therefore, this study examined the associations between Physical Activity (PA), Health-Related Quality of Life (HRQoL), and regimen adherence on glycemic control in a Middle Eastern population of adolescents with T1DMethodsThe study utilized a cross-sectional design of Jordanian adolescents (aged 12–18) with T1D (n = 74). Self-reported measures used were the Pediatric Quality of Life-Diabetes Module, the International Physical Activity Questionnaire, and the Summary of Diabetes Self-Care Activities. HbA1c values were obtained from the medical records. Correlation analyses were conducted using Pearson’s and Spearman’s correlation tests. Multiple regression analyses were conducted to determine if HRQoL, PA, and regimen adherence predict glycemic control.ResultsOnly 14.8 % of the participants demonstrated good glycemic control (HbA1c ≤ 7.5 %). Participants with poor control had a statistically significant lower mean PA of MET-minutes/week (3531.9 ± 1356.75 vs. 1619.81 ± 1481.95, p < .001) compared to those with good control. The total sample was found to demonstrate low HRQoL (47.70 ± 10.32). Participants were within the acceptable range of PA (1885.38 ± 1601.13) MET-minutes/week. HbA1c significantly inversely correlated with PA (r = −0.328, p = .010) and regimen adherence (r = −0.299, p = .018). The regression analysis revealed that PA significantly predicted glycemic control (β = −0.367, p < .01) as adherence (β = −0.409, p < .01) and disease duration did (β = 0.444, p < .01).ConclusionBetter glycemic control was significantly associated with higher PA and regimen adherence levels. The correlation between PA and glycemic control depends highly on the level of regimen adherence or arguably, adherence acts as a buffer in the correlation between PA and glycemic control. There was no significant association between glycemic control and HRQoL.
