AbstractObesity and obesity induced type 2 diabetes development and progression have been associated with sedentary lifestyle. Irisin, a newly discovered myokine, has been demonstrated at lower levels in obese and type 2 diabetes patients compared to controls. The main aim of this study is to explore association of Irisin with diabetic retinopathy (DR). A total of 233 healthy and adults participated in this study. Participants were divided into four categories: a healthy control group and an age-match subset of patients with type 2 diabetes; a positive control group of patients with type 2 diabetes not affected by DR (No DR); and patients with type 2 diabetes affected by DR (non-proliferative DR (NPDR) and proliferative DR (PDR)). Plasma samples were quantified for Irisin measurement, lipid profile and HbA1c. Comparison of the age-matched groups of healthy controls and patients with type 2 diabetes revealed lower Irisin plasma level in type 2 diabetes group. Analyses revealed negative correlations of Irisin to HbA1c and LDL levels and positive correlation to HDL level. Comparing Irisin level in No DR and DR groups revealed a higher level in No DR group and analysis per DR classification indicated higher Irisin level in NPDR group. Our results demonstrate not only correlation of plasma Irisin level with DR stages, but also significantly different Irisin level among them. This is promising in terms of researching Irisin as a potential associating marker for type 2 diabetes and DR development and progression.

Periodontitis and type 2 diabetes are co-morbid conditions, both characterized by infectious susceptibility. We investigated procalcitonin (ProCT) levels in the serum and saliva of persons with periodontitis and type 2 diabetes (n = 20), to determine if these levels are altered by periodontitis activity or by hyperglycemia. Persons with severe periodontitis showed higher levels of salivary-ProCT than did those with moderate periodontitis (241 ± 71 vs. 77 ± 516 pg/mL, p = 0.02) and higher levels than did healthy control individuals (118 ± 26 pg/mL, p = 0.05). Salivary-ProCT levels were correlated with bleeding-on-probing (r = 0.45, p = 0.05), as well as with HgbA1c (r = 0.49, p = 0.03). Salivary levels of ProCT were higher than serum levels for the periodontitis/diabetes group (152 ± 37 vs. 78 ± 17 pg/mL, p = 0.02) and the control group (118 ± 146 vs. 48 ± 17 pg/mL, p = 0.01). Persons with periodontitis and type 2 diabetes have salivary-ProCT levels that reflect their degree of periodontitis activity and hyperglycemia. This study demonstrates, for the first time, the presence of procalcitonin (ProCT), an established serum marker of infection, in saliva.

Background Type 2 Diabetes Mellitus is produced by cell failure of pancreatic cells and insulin resistance and is a disorder in which the amount of sugar in the blood is elevated. Angiopoietin-like protein 4 (ANGPTL4) functions as an inhibitor of lipoprotein lipase, a critical enzyme in lipid metabolism. The aim of this study was to explore if the ANGPTL4 gene's E40K variant and ANGPTL4 serum levels are related to the Body mass index, fasting glucose levels, lipid levels, and glycated hemoglobin.Method75 people were enrolled in this case-control study, 25 of whom had type 2 diabetes mellitus while the other 50 were healthy control subjects. Fasting blood glucose, Lipid profile, Glycated hemoglobin were estimated by Cobas 111 analyzer, BMI (weight, height) was calculated, angiopoietin-like protein 4by anenzyme-linked immune sorbent test kit and TaqMan genotyping-based real-time PCR was used to ascertain ANGPTL4 genotypes. The variant was linked to the risk of Type 2 Diabetes Mellitus and parameters used to quantify the variant were identified. Result Patients in the 30-50 age range with type 2 diabetes and those in the same age group who serve as controls. The control group had a lower level of angiopoietin-like protein 4 (ANGPTL4) than the diabetes group. Patients with T2DM had a substantially (p< 0.0001) greater fasting serum Angiopoietin-like protein 4 level than the control group (135.1±6.70) ng/ml and (62.35±6.4) ng/ml, respectively. The diabetes group has significantly higher fasting serum glucose, lipid profile, and glycated hemoglobin compared with non-diabetics. Serum Angiopoietin-like protein 4 was correlated positively with body mass index. (CC,CT,TT) genotypes of the rs2010871 polymorphism There was a significant difference in frequency of the control group (p =0.0477); however, there was no significant difference in its level of (diabetics, newly diagnosed type 2 diabetic before treatment)p-value (0.7066, 0.5555) respectively Conclusion Serum Angiopoietin-like protein 4 levels are negatively correlated to cholesterol, positively correlated to triglyceride, negatively correlated to HDL, positively correlated to HbA1c, negatively correlated to LDL, negatively correlated to VLDL, negatively correlated to FBS, negatively correlated to BMI. The C>T allele at the ANGPTL4 gene's rs2010871polymorphic locus was linked to a decreased prevalence of Type 2 diabetes.

Abstract Background To investigate the correlation between the thickness of epicardial adipose tissue (EAT), C-reactive protein (CRP), interleukin (IL) -6, visfatin, juxtaposed with another zinc finger protein 1 (JAZF1) and type 2 diabetic mellitus (T2DM) macroangiopathy. Methods The study enrolled 82 patients with T2DM with macroangiopathy (the Complication Group), and 85 patients with T2DM (the Diabetes Group) who were admitted to Shandong Provincial Third Hospital from February 2018 to February 2020. In addition, 90 healthy people who underwent physical examination at the same hospital during the same period were enrolled (the Healthy Control Group). Age, gender, height, weight, waist circumference (WC), hip circumference (HC), diabetic course and therapeutic drugs, waist hip ratio (WHR), and body mass index (BMI) were recorded and calculated. Results The baseline characteristics of the three groups were comparable, and the diabetic course of the Complication Group and the Diabetes Group was not significantly different (P > 0.05). The WHR of the Complication Group was higher than that of the Diabetes Group and the Healthy Control Group, with statistical significance (P < 0.05). The FPG, 2hPG, HbA1C, CRP, IL-6, Visfatin, JAZF1, HOMA-IR, EAT thickness, and baPWV of the Complication Group were all higher than those of the Diabetes Group and the Healthy Control Group (P < 0.05, respectively). The JAZF1 and FIns of the Complication Group and Diabetes Group were lower than those of the Healthy Control Group, and JAZF1 of the Complication Group was lower than the Diabetes Group with statistical significance (P<0.05, respectively). Pearson correlation analysis showed that the EAT thickness was positively correlated with CRP, IL-6, visfatin, and JAZF1 (r = 0.387, 0.451, 0.283, 0.301, respectively, all P<0.001). Pearson correlation analysis showed that baPWV was positively correlated with EAT thickness, CRP, IL-6, visfatin, and JAZF1 (r = 0.293, 0.382, 0.473, 0.286, respectively, all P < 0.001). Multivariate stepwise regression analysis showed that FPG, 2hPG, HbA1C, CRP, IL-6, visfatin, JAZF1, and EAT thickness were independent risk factors that affected T2DM macroangiopathy. Conclusions Clinical monitoring and treatment of T2DM macroangiopathy can use CRP, IL-6, Visfatin, JAZF1, and EAT thickness as new targets to delay the progression of the disease. Further research on the relationship between the above factors and the pathogenesis of T2DM macroangiopathy may be helpful provide new treatment strategies.

Aim. The incidence of thyroid cancer is increasing worldwide. The prevalence of type 2 diabetes mellitus (T2DM) is also increasing. Therefore, we aimed to analyze the effect of T2DM on thyroid cancer. Methods. A case-control study was performed. A total of 415 healthy controls with thyroid ultrasound screening and physician consultation were selected from the Thyroid Cancer Longitudinal Study (T-CALOS). Among patients with thyroid cancer who were enrolled in T-CALOS, 415 patients were matched to the control group according to age and sex. We assessed the effects of T2DM, T2DM duration, and T2DM medication on thyroid cancer. Results. Women with T2DM had lower odds of thyroid cancer than women without T2DM (odds ratio [OR]: 0.40, 95% confidence interval [CI]: 0.20–0.81). Individuals receiving T2DM medication had higher odds of thyroid cancer compared to those without T2DM medication (OR: 5.21, 95% CI: 1.58–17.15). Individuals with T2DM duration <6 years had lower odds of thyroid cancer compared to those without T2DM (OR: 0.58, 95% CI: 0.34–0.97). Conclusions. Individuals with early T2DM are presumed to have a low incidence of thyroid cancer, and this effect seems to last up to 6 years after diagnosis of T2DM.

Backround: Elabela (ELA) is a hormone that is secreted at high levels in the kidneys of a healthy adult. This study aims to investigate whether serum ELA levels of patients with Type 2 Diabetes vary with the severity of renal damage. Methods: Our study included 50 healthy control subjects and 100 diabetic patients, who were categorized into groups based on urine albumin/creatinine ratios (ACR). Patients included in the study were assigned to four groups: Group 1 (healthy control), Group 2 (ACR<29mg/g), Group 3 (ACR=30-299 mg/g), and Group 4 (ACR>300 mg/g normal or high serum creatinine). Physical examination findings, demographic characteristics of the study group were recorded, and serum ELA levels and other laboratory parameters were assessed using appropriate methods. Results: The results of the study indicated that ELA levels determined in healthy individuals gradually decreased through stages of normal albuminuria, microalbuminuria, and macroalbuminuria. Moreover, ELA had a significant negative corre- lation with LDL-C (r=-0.201, p=0.014), glucose (r=-0.437, P<0.001), retinopathy (r=-0.222, P=0.006), serum BUN (r=- 0.161, P=0.049), and a positive correlation with eGFR (r=0.250, P=0.002). Conclusions: The fact that ELA levels are higher in healthy individuals compared to diabetic patients without microalbu- minuria, and higher in diabetic patients without microalbuminuria compared to patients with advanced albuminuria and kidney damage, suggests that the ELA level can be an important clinical prognostic variable and even a promising agent for the treatment of diabetic nephropathy patients. Keywords: Elabela, diabetes, diabetic kidney disease, albuminuria.

ObjectiveSkeletal muscle fat content is one of the important contributors to insulin resistance (IR), but its diagnostic value remains unknown, especially in the Chinese population. Therefore, we aimed to analyze differences in skeletal muscle fat content and various functional MRI parameters between diabetic patients and control subjects to evaluate the early indicators of diabetes. In addition, we aimed to investigate the associations among skeletal muscle fat content, magnetic resonance parameters of skeletal muscle function and IR in type 2 diabetic patients and control subjects.MethodsWe enrolled 12 patients (age:29-38 years, BMI: 25-28 kg/m2) who were newly diagnosed with type 2 diabetes (intravenous plasma glucose concentration≥11.1mmol/l or fasting blood glucose concentration≥7.0mmol/l) together with 12 control subjects as the control group (age: 26-33 years, BMI: 21-28 kg/m2). Fasting blood samples were collected for the measurement of glucose, insulin, 2-hour postprandial blood glucose (PBG2h), and glycated hemoglobin (HbAlc). The magnetic resonance scan of the lower extremity and abdomen was performed, which can evaluate visceral fat content as well as skeletal muscle metabolism and function through transverse relaxation times (T2), fraction anisotropy (FA) and apparent diffusion coefficient (ADC) values.ResultsWe found a significant difference in intermuscular fat (IMAT) between the diabetes group and the control group (p&lt;0.05), the ratio of IMAT in thigh muscles of diabetes group was higher than that of control group. In the entire cohort, IMAT was positively correlated with HOMA-IR, HbAlc, T2, and FA, and the T2 value was correlated with HOMA-IR, PBG2h and HbAlc (p&lt;0.05). There were also significant differences in T2 and FA values between the diabetes group and the control group (p&lt;0.05). According to the ROC, assuming 8.85% of IMAT as the cutoff value, the sensitivity and specificity of IMAT were 100% and 83.3%, respectively. Assuming 39.25ms as the cutoff value, the sensitivity and specificity of T2 value were 66.7% and 91.7%, respectively. All the statistical analyses were adjusted for age, BMI and visceral fat content.ConclusionDeposition of IMAT in skeletal muscles seems to be an important determinant for IR in type 2 diabetes. The skeletal muscle IMAT value greater than 8.85% and the T2 value greater than 39.25ms are suggestive of IR.

Abstract There is a close relationship between melatonin as a circadian regulator and insulin, glucagon and somatostatin production. This study aimed to describe subgroups of type 2 diabetes mellitus (T2DM) patients that may benefit from melatonin clock-targeting properties. The study involved 38 participants: 26 T2DM patients, and 12 participants without diabetes in the control group. Subjects were asked to complete the questionnaire of Pittsburgh Sleep Quality Index (PSQI). Standard biochemical venous sample testing was performed, and a sample of saliva was collected for melatonin testing. Melatonin concentration in participants without obesity (body mass index (BMI) < 30 kg/m2) was significantly higher than in obese participants: 13.2 (6.4; 23.50) pg/ml vs 5.9 (0.78; 13.1) pg/ml, p = 0.035. Subjects with BMI 30 kg/m2 had a significantly higher PSQI score than non-obese subjects: 7 (4.5; 10) vs 5.5 (3; 7), p = 0.043. T2DM patients showed significantly lower levels of melatonin than the control group: 6.1 (0.78; 12.2) pg/ml vs 17.8 (8.2; 25.5) pg/ml, p = 0.003. T2DM patients using short-acting insulin analogues showed a significantly higher PSQI score than patients not using insulin: 9 (6; 10) vs 6 (3; 8), respectively (p = 0.025). Poor sleep quality was more prevalent in patients with diabetic retinopathy than in those without this complication (p = 0.031). Lower melatonin levels were detected in T2DM and obese patients. Furthermore, poor sleep quality was observed in T2DM patients using short-acting insulin analogues and those with diabetic retinopathy, and obese individuals.

Objective: Apolipoprotein B (APOB) plays an important role in the metabolism of cholesterol and impairment in its function can lead to cholesterol accumulation in the pancreatic islets. It can then reduce insulin secretion and lead to Type 2 diabetes (T2DM). The purpose of this study was to investigate the association of 3chr('39')APOB-VNTR polymorphism with plasma lipid profiles in T2DM individuals in Khorasan Razavi province, Iran. Materials and Methods: In this case-control study, 204 patients with T2DM and 207 non-diabetic volunteers were examined as a control group. All samples were analyzed for plasma lipid profiles. Genotypes were determined by PCR and electrophoresis. Differences in lipid variables between genotypes were assessed using one-way analysis of variance (ANOVA) with SPSS 20.0. Results: We found 18 different alleles of the APOB gene 3chr('39')VNTR comprising from 26 to 45 hypervariable elements (HVEs) in the control groups and 21 alleles ranging from 30 to 51 repeats in the T2DM patients. Short alleles (26 to 29 HVEs) were only in controls and large alleles (46 to 51 HVEs) were only in T2DM patients. Our results showed that in people with long HVE polymorphism, HDL-C levels decreased, but LDL-C increased. Therefore, longer alleles for T2DM are considered risk factors. It was also observed that the TC / HDL-C ratio was significantly lower in shorter genotypes than the longer genotypes in T2DM patients. Conclusion: It is concluded that 3chr('39')APOB-VNTR polymorphisms, especially longer alleles, affect plasma lipid levels in individuals with T2DM and are risk factors for this disease.
