The percussion entropy index (PEIorginal) was recently introduced to assess the complexity of baroreflex sensitivity. This study aimed to investigate the ability of a speedy modified PEI (i.e., PEINEW) application to distinguish among age-controlled subjects with or without diabetes. This was carried out using simultaneous photo-plethysmo-graphy (PPG) pulse amplitude series and the R wave-to-R wave interval (RRI) series acquired from healthy subjects (Group 1, number = 42), subjects diagnosed as having diabetes mellitus type 2 with satisfactory blood sugar control (Group 2, number = 38), and type 2 diabetic patients with poor blood sugar control (Group 3, number = 35). Results from PEIorginal and multiscale cross-approximate entropy (MCAE) were also addressed with the same datasets for comparison. The results show that optimal prolongation between the amplitude series and RRI series could be delayed by one to three heartbeat cycles for Group 2, and one to four heartbeat cycles for Group 3 patients. Group 1 subjects only had prolongation for one heartbeat cycle. This study not only demonstrates the sensitivity of PEINEW and PEIorginal in differentiating between Groups 2 and 3 compared with MCAE, highlighting the feasibility of using percussion entropy applications in autonomic nervous function assessments, it also shows that PEINEW can considerably reduce the computational time required for such processes.

Abstract Introduction/Objective Introduction: Type-2 diabetes have a risk factor of multiple complications such as coronary artery diseases (CAD), premature atheroscalerosis and diabetic retinopathy. IGF-1 is regulated by a balance of hormones such as growth hormone and insulin. It is important that circulating IGF1 in serum has normal levels to maintain glucose metabolism. Objectives: Monitoring of IGF-1levels in T2DM with macrovascular complications (CVD) and microvascular complications (retinopathy). Methods Subjects and methods: The collection of samples started in June 2018 and ended in December 2018. A total of 114 subjects were enrolled in this study; 98 clinically diagnosed T2D patients who were recruited from the outpatient clinic of the National Institute for Diabetes and Endocrinology “NIDE”, in addition to 16 healthy comparable control subjects (without diabetes). The subjects divided into 3 groups. Group 1; a population of 44 T2D patients with macrovascular complications (28 females and 16 males), the mean age was 57.4 years. Group 2; a population of 54 T2D patients with microvascular complicatios (34 females and 20 males), the mean age was 59.1 years. Group 3; a population of 16 healthy subjects (12 female and 4 males), the mean age was 59.2 years. Levels of FBS, C-peptide, HbA1c, Lipid profile, lipoprotein(a), hs-CRP and microalbuminurea were measured in all subjects. Seum concentration of IGF-1 was measured by commercially immunoenzymatic ELIZA method. Results It was found that serum concentration of IGF-1 decreased in diabetic patients groups compared to the control one. The mean±SD of group 1, group 2 and group 3 were (332.2±152.2), (316.9 ±142.2) and (625.4 ± 257.7) respectively. Conclusion It was observed that there was a negative correlation between serum IGF-1 levels in T2D patients compared to the control group. Also, it was found that T2D patients with microvascular complications had lower IGF-1 levels than patients with macrovascular ones. It seems that IGF-1 strongly involved in the incidence and pathogenesis of T2DM complications.

Aims: This study aimed to investigate the relationship between microalbuminuria and hypertension in type 2 diabetic patients. Study Design: It was a descriptive type of cross-sectional study. Place and Duration of Study: The study was conducted in collaboration at a diabetic clinic and Hypertension and Research Centre, Rangpur, Bangladesh from January to March 2018. Methodology: A total of 180 diabetic patients were selected purposively age ranges 30-75 years. Anthropometric as well as biochemical measurement was done. Data was collected by a semi-structured questionnaire through face to face interview and analyzed by SPSS-20. Results: Study subjects were separated into two groups. Group 1, those with normoalbuminuria (n=49) and Group 2, those having microalbuminuria (n=131). The prevalence of microalbuminuria was 72.8%. Group 2 or microalbuminuric patients showed higher blood pressure values (113.50±8.90 mm of Hg) as compared to Group 1 (101.88±9.80 mm of Hg). The results were statistically significant (P≤0.05). Further this study showed fasting blood sugar, duration of diabetes, systolic blood pressure and high level of sCreatinine were independently associated with microalbuminuria in the study subjects. The results were also statistically significant (P≤0.05). Conclusion: Our study revealed high prevalence of microalbuminuria in diabetic patients and has an optimistic association with blood pressure. This study suggests the need to screen for microalbuminuria early and the active management of modifiable risk factors in particular fasting blood sugar, sCreatinine, hypertension for intervention and prevention of further complications like end stage renal disease and cardiovascular diseases.

ABSTRACT Background: Co-morbid diabetes and depression are prevalent chronic conditions negatively affecting quality of life (QoL). Inflammation has been considered as an integral mechanism in patients with both diabetes and depression. Objective: The aim of the present study was to investigate depression and its association with interleukins (IL)-1β and IL-9 in type 2 diabetic patients (T2DM) and controls. The QoL in diabetic patient was also assessed. Methods: Eighty subjects were included, distributed among three groups: Group 1 - Healthy controls; Group 2 - T2DM patients without depression; Group 3 - T2DM patients with depression. Depression and QoL were assessed using Patient Health Questionnaire (PHQ-9) and The Audit of Diabetes-Dependent QoL (ADDQoL), respectively. IL-1β and IL-9 were measured in serum samples of all the patients using ELISA kit. Results: The PHQ score in the Group 3 was significantly higher as compared to Group 1. The ADDQoL scores in the Group 3 were significantly higher as compared to Group 2. Levels of IL-9 and IL-1β were elevated in Group 3, as compared to the other groups. Conclusion: This study showed positive association between depression and IL-1β, IL-9 in T2DM patients. Additionally, the diabetic patients have poorer quality of life, which is further worsened by the presence of depression. Thus, routine assessment for the presence of depression is suggested in T2DM patients.

Multiple association studies found that the human 9p21.3 chromosome locus is a risk factor for atherosclerosis. The purpose of this study was to investigate the association of the severity and early-onset of coronary artery disease with variant rs1333049 on chromosome 9p21.3 polymorphism and the impact of this variant on cardiovascular risk factors in type 2 diabetic patients. The study population consisted of a control CAD group (101 patients) and 273 consecutive type 2 diabetic patients. Severity and extent of coronary atherosclerosis were scored numerically using the Gensini scoring system. The diabetic population was divided into three groups according to Gensini score: Group 1: no stenosis; Group 2: moderate CAD; Group 3, severe CAD. The homozygous CC genotype of rs1333049 was significantly associated with CAD in Group 2 (OR: 1.36;p=0.02) and Group 3 (OR: 5.77,p<0.001) compared to Group 1 (OR: 0.18;p=0.2) and control group (OR: 0.22;p=0.21). Among diabetic patients with early-onset CAD, CC genotype carriers had significantly higher Gensini scores than non-CC genotype carriers (49±21.3versus14.87±25.22;p<0.001). The homozygous CC genotype of rs1333049 confers a magnified risk of early-onset and severe CAD in type 2 diabetic Tunisian population.

Lipid profile could be modified by Mediterranean diet (MD) and by red yeast rice (RYR). We assessed the lipid-lowering effects of MD alone or in combination with RYR on dyslipidemic statin-intolerant subjects, with or without type 2 diabetes, for 24 weeks. We evaluated the low-density lipoprotein (LDL) cholesterol level, total cholesterol (TC), high-density lipoprotein (HDL) cholesterol, triglyceride, liver enzyme, and creatinine phosphokinase (CPK) levels. We studied 171 patients: 46 type 2 diabetic patients treated with MD alone (Group 1), 44 type 2 diabetic patients treated with MD associated with RYR (Group 2), 38 dyslipidemic patients treated with MD alone (Group 3), and 43 dyslipidemic patients treated with MD plus RYR (Group 4). The mean percentage changes in LDL cholesterol from the baseline were-7.34±3.14% (P<0.05) for Group 1;-21.02±1.63% (P<0.001) for Group 2;-12.47±1.75% (P<0.001) for Group 3; and-22±2.19% (P<0.001) for Group 4 with significant intergroup difference (Group 1 versus Group 2,P<0.001; Group 3 versus Group 4,P>0.05). No significant increase in AST, ALT, and CPK levels was observed in all groups. Our results indicate that MD alone is effective in reducing LDL cholesterol levels in statin-intolerant patients with a presumably low cardiovascular risk, but associating MD with the administration of RYR improves patients’ LDL cholesterol levels more, and in patients with type 2 diabetes.

Background: Microalbuminuria is one of the earliest markers of diabetic nephropathy, and if not recognized and treated early it may lead to diabetic nephropathy resulting in chronic renal failure. Aims and Objective: The aim of the current study was to find out the prevalence of microalbuminuria among newly detected Type 2 diabetic patients and also compare prevalence of microalbuminuria in patients with or without hypertension, dyslipidaemia and obesity. Materials and Methods: In this retrospective study, we analysed 90 patients with new onset type 2 diabetes mellitus. We divided the patients into two groups, group 1 with comorbidities like hypertension, dyslipidaemia and obesity (50 patients) and group 2 without comorbidities (40 patients). We analysed urinary microalbumin level in all patients and compared the prevalence of microalbuminuria between group 1 and group 2. Results: In our cohort of 90 patients, urinary microalbuminuria was found in 30 patients (33.3%). When we divided these nephropathy patients to group1 and group 2, we observed that group 1 with comorbidities had higher percentage of nephropathy patients i.e 24 out of 50(48%). Group 2 with 40 patients had only 6 patients with microalbiminuria ie 6 out of 40(15%). Incidence of microalbiminuria was higher in patients with hypertension, dyslipidaemia and obesity. Conclusions: We conclude that incidence of microalbiminuria is much more common in newly diagnosed type 2 diabetes. We also conclude that hypertension, obesity and hypercholesterolemia are risk factors for nephropathy and urinary microalbuminuria appears to be much more sensitive than serum creatinine as screening tool to detect diabetic nephropathy.

Background: Type 2 diabetes mellitus patients frequently have various distressing gastrointestinal signs and symptoms and intestinal alkaline phosphatase (IAP) may be linked to it. Even after extensive search, there was dearth of literature related to IAP levels in serum of diabetic enteropathy subjects. So, using a case-control design, levels of IAP in the serum of T2DM subjects were determined.Methods: Serum IAP was measured by ELISA in 73 type 2 diabetic patients with enteropathy (group 1) and 71 type 2 diabetic patients without enteropathy (group 2). Statistical analysis of the data was performed by using Statistical Package for Social Sciences (SPSS version 16) and inferences were drawn.Results: Serum IAP was highly significantly reduced in group 1 (3.9 U/L) compared to group 2 (4.2 U/L).Conclusions: Enteropathy in T2DM may be related to reduction in IAP levels in serum. Estimation of serum IAP may be considered in type 2 diabetic patients with enteropathy, for the elaboration of treatment strategy and monitoring.

Background: The increasing prevalence of type 2 diabetes in India is a cause for national concern, particularly the spiraling cost burden to the country. As one approach to stop its increase, Yoga medicine has been widely implemented, finding popularity with all social strata. Here, we report a study suggesting that treatment with fresh herbal juices and Yoga can improve the levels of blood glucose and hemoglobin A1c (HbA1c) in people with pre-diabetes. Methods: Study design: 3-arm controlled trial 3 months in duration. Participants: 157 male prisoners with newly diagnosed, high fasting blood sugar (FBS) and postprandial blood sugar (PPBS) levels. Group interventions: (1) Rasahara and Yoga, (2) Yoga, (3) no intervention. Assessments: FBS and PPBS levels were measured every 2 weeks; HbA1c and blood lipids were determined pre- and post-intervention. Results: Significant decreases occurred in the FBS (-21.13 ± 21.16 mg/dl) and PPBS levels (-15.02 ± 14.89 mg/dl) in group 1 (both p < 0.0001) and in the FBS level (20.62 ± 32.68 mg/dl) in group 2 (p = 0.0005), while the increases in group 3 attained significance only for the PPBS level (9.62 ± 21.83 mg/dl) (p = 0.0022). Observed changes in HbA1c were: group 1, -0.044 ± 0.059 mg/dl; group 2, +0.024 ± 0.456 mg/dl (not significant); and group 3, +0.365 ± 0.369 mg/dl (p < 0.0001). Conclusions: This study of Yoga for the treatment of diabetes shows that all male prisoners could benefit from the Yoga prison programs. Addition of Yoga programs to state and federal activities at all levels is now national policy in India. Follow-up studies should be carried out to obtain more robust results.

Objective. To evaluate liraglutide (LIR) endothelial protective action. Material and methods. Type 2 diabetic patients with HbA1C 7.5-9.0 % had metformin (MET) dose titrated for 3 months. Patients with HbA1C less than 7.5 % comprised group 1 (MET), more than 7.5 % - group 2 (MET+LIR). Blood concentrations of tissue plasminogen activator (t-PA), plasminogen activator inhibitor-1 (PAI-1), endothelin-1 (E) were evaluated at baseline, in 3, 6 and 9 months. Results. PAI-1 was increased in both groups and gradually decreased. T-PA was normal. E was primarily increased only in group 2. E was normal in group 1 in general, but enlarged with glycaemia increase. E decreased in group 2 with glycaemia improvement and worsening. Conclusions. Glycaemia control improvement decreases endothelial dysfunction. LIR improves vasomotor endothelial function, independently on its influence on glycaemia.

1.BACKGROUND: Overweight and obesity are global public health problem with increasing prevalence worldwide1-3. It is a risk factor for many metabolic and cardiovascular diseases including type 2 diabetes, hypertension, and dyslipidaemia etc4. Diabetic retinopathy (DR) is the common micro vascular complication of diabetes mellitus (DM) and a leading cause of acquired blindness in adults. The aim of this study is nd relationship between different BMI classes and DR development in type 2 diabetic patients. 2. AIMS AND OBJECTIVES:To determine the association of BMI and diabetic retinopathy and risk factors for DR 3. MATERIALS AND METHODS: A total of 206 type 2 diabetes patients from medicine ward of Swai man singh hospital and college Jaipur [Rajasthan]. The subjects were classied into one of the three categories according to the BMI. (1).Normal BMI 18.5–24.9 kg/m2; (2).Overweight BMI 25–29.9 kg/m2.(3).Obese BMI ≥30 kg/m2. Blood samples were collected after overnight fasting. Glycated haemoglobin value (HbA1c), total cholesterol and triglycerides were measured. Complete eye examination included best corrected visual acuity (BCVA), slit lamp microscopy, and fundus examination with binocular indirect ophthalmoscope and plus 20D lens after mydriasis with topically administrated 1% tropicamide and 5% phenylephrine eye drops was done. According to the DR status, patients were divided into two groups: group 1 (no retinopathy; N= 168), group 2 diabetic retinopathy; N= 38) RESULT: Duration of type 2 diabetes was found longer with group 2 (9.6±4.5 years) as compare with group 1 (16.82±7.21 years). Association of body mass index (BMI) of type 2 diabetic patients (n =206) with diabetic retinopathy, no correlation was found with mean BMI in group 1 (25.48 ± 2.4) and group 2 (27.21± 2.0)( P value <0.1). In our study were found signicant correlation of HbA1c with DR (p value <.01). Mean value of HbA1c was higher in group 2 (8.41±.6) as compare with group 1 (7.01±.8). We found a signicant increase in total cholesterol (P <.01), triglycerides (P< 0.05) with the diabetic retinopathy
