Aim. To study the relationship between changes in the artery structure and function and peripheral lymphocyte telomere length in patients with type 2 diabetes mellitus (DM2). Materials and methods. A total of 50 patients with T2DM and without clinical manifestations of cardiovascular disease (CVD) were included in the study; the control group consisted of 49 people. The following tests were conducted for all study participants: carbohydrate metabolism evaluation, carotid artery duplex scan to measure intima?media complex thickness (IMT) and to determine the presence of atherosclerotic plaques, carotid?femoral pulse wave velocity (PWV) measurement and lymphocyte telomere length measurement. Results. The vascular changes were more pronounced in patients with T2DM than in controls. The telomeres were shorter in patients with T2DM than in those without diabetes (9.53?0.1 vs 9.86?0.1, p=0.033). The participants were divided according to the telomere length. Among patients with T2DM, there were significant differences in the condition of the vascular wall [PWV: 10.58?0.1 m/s in patients with ?long? telomeres and 15.08?1.3 m/s in patients with ?short? telomeres; IMT: 0.80?0.09 mm in patients with ?long? telomeres and 0.87?0.05 mm in patients with ?short? telomeres (p=0.024)]. There were no significant differences in the arterial structure between the patient and control groups with ?long? telomeres [PWV: 10.58?0.1 m/s vs 10.5?0.5 m/s (p=0.913); IMT: 0.080?0.09 mm vs 0.73?0.03 mm (p=0.12). However, there were significant differences in the vascular wall condition between the patient and control groups with ?short? telomeres [PWV: 15.08?1.3 m/s vs, 10.7?0.5 m/s (p=0.015); IMT: 0.87?0.1 vs 0.78?0.1 (p=0.03)]. Conclusions. The signs of vascular ageing were more pronounced in patients with T2DM than in controls. However, despite diabetes, vascular changes were minimal in patients with ?long? lymphocyte telomeres, comparable with the state of the vascular walls in healthy individuals. Thus, enhanced lymphocyte telomere length may have a protective effect on the vascular wall and may prevent damage from carbohydrate metabolism disorders.

o study the association of serum leptin and glucose/leptin ratio with microalbuminuria in patients with type 2 diabetes mellitus at different durations, and to predict their effect on their renal function. A case control study was conducted in the International Diabetic Center at Al-Mustansiryia University in Baghdad-Iraq from 1st September 2008 to the 30th of July 2010. One hundred and eight male patients with type 2 diabetes mellitus (DM) were introduced in this study. Fifty three healthy subjects were used as a control. Fasting serum glucose, insulin, leptin, urea, creatinine and body mass index were estimated in both patient and control groups. Fifty three 49.07% out of 108 were diabetic for ≤2 years, while 55 patient 50.93% were diabetic >2 years. All patients were obese while healthy control subjects were not. Fasting serum glucose, insulin and leptin levels were found elevated in patients group while in control group their levels were found within normal range. Both urea and creatinine were also within the normal range for patients and control groups. Level of albumin in urine of patients with diabetes mellitus for ≤ 2years was found normal while in those with 3 to 6 or more than 6 years of DM, level of urinary albumin was found within the micro rang. A positive correlation with highly significant p value (<0.01) was found between patients (≤ 2 years and >2 years) serum leptin, glucose/leptin ratio and microalbuminuria. Conclusions: a strong association was found between serum leptin and glucose/leptin ratio with microalbuminuria in type 2 diabetic patients which can be used to predict the efficiency of their renal function at different durations and can be used as additional marker for the diagnosis of early stage of nephropathy.

Since periodontitis and type 2 diabetes mellitus are complex diseases, a thorough understanding of their pathogenesis requires knowing the relationship of these pathologies with other disorders and environmental factors. In this study, the representability of the subgingival periodontal microbiome of 46 subjects was studied by 16S rRNA gene sequencing and shotgun sequencing of pooled samples. We examined 15 patients with chronic periodontitis (CP), 15 patients with chronic periodontitis associated with type 2 diabetes mellitus (CPT2DM), and 16 healthy subjects (Control). The severity of generalized chronic periodontitis in both periodontitis groups of patients (CP and CPT2DM) was moderate (stage II). The male to female ratios were approximately equal in each group (22 males and 24 females); the average age of the subjects was 53.9 ± 7.3 and 54.3 ± 7.2 years, respectively. The presence of overweight patients (Body Mass Index (BMI) 30–34.9 kg/m2) and patients with class 1–2 obesity (BMI 35–45.9 kg/m2) was significantly higher in the CPT2DM group than in patients having only chronic periodontitis or in the Control group. However, there was no statistically significant difference in all clinical indices between the CP and CPT2DM groups. An analysis of the metagenomic data revealed that the alpha diversity in the CPT2DM group was increased compared to that in the CP and Control groups. The microbiome biomarkers associated with experimental groups were evaluated. In both groups of patients with periodontitis, the relative abundance of Porphyromonadaceae was increased compared to that in the Control group. The CPT2DM group was characterized by a lower relative abundance of Streptococcaceae/Pasteurellaceae and a higher abundance of Leptotrichiaceae compared to those in the CP and Control groups. Furthermore, the CP and CPT2DM groups differed in terms of the relative abundance of Veillonellaceae (which was decreased in the CPT2DM group compared to CP) and Neisseriaceae (which was increased in the CPT2DM group compared to CP). In addition, differences in bacterial content were identified by a combination of shotgun sequencing of pooled samples and genome-resolved metagenomics. The results indicate that there are subgingival microbiome-specific features in patients with chronic periodontitis associated with type 2 diabetes mellitus.

And Control

Type 2 diabetes mellitus (T2DM) is a major risk factor for cardiovascular complications including ischemia reperfusion injury (IR). Activation of mitochondrial KATP channels by Diazoxide (DZX) promotes beta cell rest and suppresses glucose production in patients. We hypothesized that DZX prevents IR arrhythmias in T2DM owing to its dual cardioprotective & antidiabetic property. Methods: Obese Zucker Diabetic Fatty (ZDF) rats (n=17) with established T2DM were studied. Control groups consisted of lean ZDF (n=6) and normal Sprague Dawley (n=10) rats. High resolution optical action potential (AP) mapping was performed in hearts before and after challenge with no flow ischemia for 12min followed by reperfusion. Results: Basal properties including rate dependence of conduction velocity (CV) and AP duration (APD) were not significantly (p=NS) altered in T2DM. Remarkably, ischemia uncovered major differences between groups as APD in T2DM failed to adapt to the ischemic challenge. Unlike APD, CV was reduced in all groups. DZX paradoxically promoted arrhythmias as all DZX (30uM) treated T2DM hearts exhibited ischemia related VT. In contrast, untreated T2DM (0/5) and control (0/9) hearts did not exhibit VT during ischemia. Underlying arrhythmic vulnerability of DZX treated T2DM hearts was a pronounced reduction (by 75% p<0.01) of the cardiac wavelength (WL) caused by accelerated APD shortening in response to ischemia. Upon reperfusion, T2DM and control groups exhibited a high (60% T2DM vs 44% control, p=NS) rate of VT, although the VT cycle length in T2DM was significantly longer (72 vs 44ms, p<0.01) suggesting a more adverse substrate modification by IR injury. Blocking the inner membrane anion channel (IMAC) fully abrogated reperfusion VT in T2DM. Conclusion: Ischemia uncovers a paradoxical resistance of T2DM hearts to APD adaptation. DZX reverses this property resulting in accelerated APD & WL shortening. This promotes reentrant VT during ischemia. Therefore, the anti-diabetic agent DZX should be avoided in T2DM patients at risk of ischemic events. Instead IMAC is an effective antiarrhythmic target for these patients.

: Hypertension and type 2 diabetes mellitus are two important risk factors that contribute to cardiovascular diseases worldwide. In Latin America hypertension prevalence varies from 30 to 50%. Moreover, the proportion of awareness, treatment and control of hypertension is very low. The prevalence of type 2 diabetes mellitus varies from 8 to 13% and near to 40% are unaware of their condition. In addition, the prevalence of prediabetes varies from 6 to 14% and this condition has been also associated with increased risk of cardiovascular diseases. The principal factors linked to a higher risk of hypertension in Latin America are increased adiposity, low muscle strength, unhealthy diet, low physical activity and low education. Besides being chronic conditions, leading causes of cardiovascular mortality, both hypertension and type 2 diabetes mellitus represent a substantial cost for the weak health systems of Latin American countries. Therefore, is necessary to implement and reinforce public health programs to improve awareness, treatment and control of hypertension and type 2 diabetes mellitus, in order to reach the mandate of the Unit Nations of decrease the premature mortality for CVD.

Background: Type 2 diabetes needs a better understanding of etiological factors and management strategies based on lifestyle and constitutional factors, given its high association rate with many cardiovascular, neurological disorders, and COVID-19 infection. Purpose: The present study was undertaken to investigate the effect of Diabetes-specific integrated Yoga lifestyle Protocol (DYP) on glycemic control and lipid profiles of diabetic adults. Along with the DYP intervention, the individuals residing in Chandigarh and Panchkula union territories in the northern part of India were assessed for Ayurveda-based body–mind constitutional type. Ayurveda describes body–mind constitution as “ prakriti,” which has been discussed from two angles, namely physiological and psychological as body and mind are correlated. Methods: Cluster sampling of waitlist control study subjects was used as the sampling method for the study. A total of 1,215 registered subjects (81 diabetic) responded in randomly selected clusters in Chandigarh and Panchkula. Ayurveda physicians did Ayurveda body–mind constitutional assessment called prakriti assessment (physiological body–mind constitution assessment) in 35 participants (23 diabetic, 12 prediabetic) as a part of the study. Results: A group of 50 subjects was randomly selected for yoga intervention out of 81 diabetes mellitus adults, and 31 subjects were enrolled as waitlist controls. A significant decrease in the glycosylated hemoglobin levels from 8.49 ± 1.94% to 7.97 ± 2.20% in the intervention group was noticed. The lipid profiles of the DYP intervention and control groups were monitored. Three-month follow-up results of lipid profile diagnostic tests in intervention and control groups showed a significant difference between the two groups ( P < 0.05). Most diabetic and prediabetic individuals were found to have pitta dosha ( pitta controls all heat, metabolism, and transformation in the mind and body) as dominant constitution type. Conclusion: The study results demonstrated significant positive effects of yoga in diabetic individuals. This study has indicated the evidence for the safety and efficacy of the validated DYP for community-level interventions to prevent maladies like brain damage and stroke.
