Abstract
Background: Diabetic patients need to be followed for glycemic index regularly and HbA1c test is one of the most important biochemical markers for patient monitoring. HbA1c should be standardized based on international standards, but using internationally accepted assays are expensive. This study aimed to evaluate cost effectiveness of different assays which are currently used in Iran.
Methods: In this economic evaluation study, five HbA1c assays (Pars Azmoon, NycoCard, DS5, Biosystems and CERA STAT 2000) have been evaluated for cost, sensitivity and specificity, true score and also incremental cost-effectiveness ratios. Tosoh G8 has been considered as reference method.
Results: Although none of the assays can be a good alternative for reference method, DS5 and pars azmoon had better cost effectiveness results compared to other assays.
Conclusion: The quality of HbA1c assays need to be improved by using real tariff or the establishment of referral labs.

Abstract
Background: One of the most common complications of Diabetic Polyneuropathy (DPN) is decreased balance and Postural Control disorder. Balance has an important role in static and dynamic activities as a base of activities of daily living. The objective of this study was the evaluation and comparison of dynamic and functional balance in patients with DPN and healthy subjects.
Methods: In this study, dynamic and functional balance of 11diabetic patients with DPN (detected by Michigan questionnaire) and 11 healthy subjects were evaluated by Biodex Balance System (BBS) and Tandem Stance (TS) test in open and closed eyes conditions. The participants were matched by age and BMI. An independent t-test was used to compare balance parameters between patient and normal group. Furthermore, the correlation between dynamic balance parameters of BBS and TS tests were calculated using the Pearson’s Correlation Coefficient.
Results: The results of BBS in patients with diabetic peripheral neuropathy were significantly higher than normal subjects (P<0.05). The mean of time of TS test in diabetic group was significantly lower than healthy subjects (P<0.05). Also there was a significant (P=0.004) negative (r = 0.794) correlation between Medio-Lateral stability index (recorded from BBS) and TS with open eye, in diabetes group.
Conclusion: Older adults with DPN have an impaired functional balance in comparison with matched control subjects and this may expose the patients to danger of falling during daily activities.

Abstract
Background: Insulin resistance and progressive β-cells failure are the key factors in type 2 diabetes mellitus (T2DM) pathogenesis. Many studies support a primary role of RBP4 in insulin resistance and suggest that genetic variations which alter the expression level of RBP4 might influence the risk of T2DM and its complications. Diabetic foot is one of the main complications of diabetes leading to disability and hospitalization. In addition, it reduces quality of life and imposes great cost to patients. The purpose of this study was to evaluate the correlation between two single nucleotide polymorphisms (rs10882273 and rs10882283) of RBP4 genes with diabetic foot ulcer in order to identify a biomarker for prediction of diabetic foot ulcer.
Methods: This is a case-control study. Two single nucleotide polymorphisms of RBP4 genes were genotyped by hit Tetra ARMS PCR technique. In this study, 100 and 133 diabetic patients with and without foot ulcer were selected as the cases and controls, respectively.
Results: The Chi-square test revealed no significant difference in frequency of TT, CC and TC alleles of rsl0882273 between case and control groups (P=0.414). Also, Comparison of AA, CC and AC alleles of rsl0882283 in both groups did not show significant difference (P=0.85).
Conclusion: According to this study, there is no relationship between two single nucleotide polymorphisms of RBP4 genes (rs10882273 and rs10882283) with diabetic foot ulcer in type2 diabetes patients.

Abstract
Background: Diabetic Nephropathy is one of the main microvascular complications of diabetic mellitus. Methylenetetrahydrofolate Reductase (MTHFR) is one of the candidate genes of diabetic nephropathy. MTHFR (C677T) polymorphism reduces catalytic activity of MTHFR and leads to increase level of plasma homocysteine. The aim of this study was to evaluate the association of C677T polymorphism with diabetic nephropathy.
Methods: In this case control study, 300 individuals, including type 2 diabetes mellitus with diabetic nephropathy (N=104), diabetes mellitus patients without diabetic nephropathy (N=100) and controls (N=96) participated. The MTHFR genotype was determined using PCR-RFLP technique and biochemical parameters were measured.
Results: Genotype frequencies were significantly different between patients with diabetic nephropathy and diabetes mellitus without nephropathy (TT+CT vs CC; P=0.02,OR:0.5,CI:0.3-0.9).The allele frequency was also significantly different between diabetic nephropathy and diabetics mellitus without nephropathy(P=0.013,OR:1.754,CI:1.123-2.740).
Conclusion: These findings suggest that there is an association between C677T polymorphism and nephropathy in patients with type 2 diabetes. Allele C increase the risk of nephropathy, and T allele has a protective role in susceptibility to disease.

Abstract
Background: Diabetic nephropathy is a chronic kidney disease and of more common complications of type 2 diabetes mellitus. The current diagnostic markers of diabetic nephropathy, albumin and creatinine, are only able to catch the disease in the stage of renal damage. The aim of this study is evaluation of targeted metabolomics of serum amino acids to identify the association of the changes of serum amino acid profile with diabetes and diabetic nephropathy.
Methods: This cross-sectional study was conducted in 2015-2016 on thirty patients with type 2 diabetes subsequent diabetic nephropathy and thirty type 2 diabetic patients without nephropathy attending diabetes clinic of endocrinology and metabolism institute and thirty non diabetic persons. Blood hemoglobin, HbA1c and BUN and also, serum albumin, uric acid and the albumin/creatinine ratio from a random urine specimen were measured by standard methods and serum amino acids level were identified using high performance liquid chromatography (HPLC). Statistical analysis ANOVA, Kruskal-Wallis, and nominal regression were used for the comparison of the investigated groups.
Results: significant differences were seen in serum levels of 8 essential, branched-chains, aromatic and 8 non-essential amino acids alanine, aspartic acid, serine, glutamine, arginine, glycine, tyrosine and ornithine between three groups. Serum levels of arginine and isoleucine were higher in the diabetic group than non-diabetics. However, Levels of amino acids serine, glutamine, glycine, threonine, tyrosine, tryptophan, methionine, valine, ornithine, and lysine in 2 groups of diabetic nephropathy and diabetes were higher than non-diabetic patients.
For every standard deviation decrease in serum levels of amino acids serine, alanine and isoleucine, in comparison to diabetic patients, the risk of diabetic nephropathy were increased 3.257 (95%CI: 0.10- 0.94, P=0.039), 2.207 (95%CI: 0.18- 0.81, P=0.039) and 2.652 (0.21- 0.96, P=0.012), respectively.
Conclusion: Since this study was conducted in patients in the early stages of the disease, reduced serum levels of the amino acids serine, leucine and alanine may be associated with development and progression of diabetic nephropathy. and in the future with more studies in this field can be used in metabolic control and improvement of the prognosis of patients with diabetic nephropathy.

Abstract
Background: Hemodialysis is the most common treatment in patients with end stage of renal disease (ESRD). Patients undergoing hemodialysis due to multiple drug treatments, special food programs and being able to cope with their illness need to self-care activities. Due to lack of information about the role of health literacy in effectiveness of self-care in these patients, this research aimed to determine the correlation between self-care and health literacy in patients undergoing hemodialysis in Valiasr Hospital of Arak in 2015.
Methods: In this descriptive correlational study, 93 undergoing hemodialysis patients selected by objective sampling method. Data collecting instruments were "demographic questionnaire", "self-care questionnaire " and "Health Literacy for Iranian Adults questionnaire". The content and face validity of questionnaires was assessed. Reliability assessed through internal consistency (Cronbach's alpha) and Intra- Class Correlation Coefficient. Data were analyzed by SPSS, version 21, using, Kolmogorov–Smirnov test, Descriptive Statistics and Kolmogorov–Smirnov test.
Results: The results showed that 79/6% of patients were male and 20/4% were female with an average age of 54/18 ± 13/9 year. The mean score of self-care and health literacy were 146/90± 45/46, 88/14± 36/42 and were at a moderate level. The lowest score of self-care and health education related to the field of fluid intake and decision-making and behavior. There was a significant positive correlation between self-care and health literacy (p<0/0001, r= 0/6).
Conclusion: The existence of a significant positive correlation between self-care and health literacy showed that the hospital managers and the nurses must pay more attention to what patients undergoing hemodialysis need. Considering the importance of health literacy in the care of patients undergoing hemodialysis, it seems necessary to nursing administrators and Politicians use educational programs tailored to the patient's health literacy level in order to promote their health and quality of life.

Abstract
Background: Prevalence of obesity and overweight in women increases the possibility of metabolic syndrome and diabetes. Based on the variety of the effects of different type of exercise and the differences in the upper and lower body muscle volume involved in the exercise, the effects of high intensity interval exercise with arm and leg ergometer on metabolism and insulin resistance might be different. The aim of this study was to compare the effect of upper and lower body interval exercise on carbohydrate metabolism and insulin resistance in obese women.
Methods: Twelve obese and overweight women (body mass index, 31.1±5.5 kg/m2) performed two interval exercise trials of 30-min on arm and leg ergometer with one week intervening. Interval exercise included 5 sets of 6 min in which 2- min activity at 85% VO2max and 4 min active rest at 45% VO2max was performed. Two blood samples were taken before and immediately after exercise for measuring glucose and insulin. VO2 and VCO2m were collected during exercise and used to calculate the amount of carbohydrate oxidation.
Result: Although interval exercise reduced the insulin concentration, responses of insulin to upper and lower body exercises were not significantly different (P>0.05). Glucose level reduced following interval exercise, and this reduction was significantly (P<0.05) higher following lower body interval exercise than upper body exercise. Similarly the reductions in HOMA-IR were significantly (P<0.05) higher following lower body interval exercise than upper body exercise. Interval exercise resulted in increases in oxidation of carbohydrate, though; responses to upper and lower exercises were not significantly different.
Conclusion: It could be concluded that interval exercise in obese women leads to changes in carbohydrate metabolism and insulin resistance, and that the changes in insulin resistance are related to type of exercise (upper and lower body), though carbohydrate oxidation is not.

Abstract
Background: Although a positive association between type 2 diabetes and breast cancer has been reported, an association with gestational diabetes mellitus (GDM) is less clear. This study aimed to assess the relationship between the history of GDM and the incidence of BC a long term population based study.
Methods: To conduct this research, 4076 women aged 20-50 years who participated in the first phase of Tehran-Lipid-and-Glucose-Study, who had at-least one pregnancy were included. Each participants were asked about the history of GDM every 3 years. They was evaluated about the occurrence of breast cancer (BC). Cox-survival analysis was used to measure the Hazard-ratio (HR) for both groups with and without history of GDM
Results: The study population included 886 women with prior GDM and 3,909 women without history of GDM. The median duration of follow-up among women with and without the history of GDM were 12.12 and 11.62 years, respectively. The incidence of BC was 0.64 per 1,000 year-olds with confidence=interval of 95% (0.44-0.91). Among them, 4 cases were reported in women with GDM and 26 cases in women without GDM. (Incidence of 0.36 per 1000 person-years with confidence=interval 95% (0.11-0.99) in women with prior GDM and 0.73 per 1,000 person-years with confidence=interval 95% (0.49-1.1) in women without a history of GDM.
Conclusion: Our study showed that the history of GDM is not an independent risk factor for breast cancer.

Abstract
Background: Diabetes mellitus is one of the most common endocrine diseases. Cardiovascular disease (CVD) is one of the leading causes of death in patients with type 2 diabetes. The aim of this study was to investigate the metabolic profile of plasma amino acids in diabetic patients with cardiovascular disease.
Methods: The present study is a descriptive-analytical cross-sectional study on 140 patients including 35 patients with type 2 diabetes and cardiovascular disease (CVD.DM), 35 patients with type 2 diabetes and non-cardiovascular disease (DM). 35 non-diabetic patients with cardiovascular disease (CVD.nDM) and 35 non-diabetic patients with non-cardiovascular disease (HS) were referred to Diabetes Clinic No. 1 of Tehran University of Medical Sciences.
Results: 76 (54.3%) were male and 64 (45.7%) were female. The highest concentrations of glutamine and isoleucine were observed in DM.CVD, asparagine, serine, arginine, threonine, alanine, tyrosine, valine in DM.nCVD and methionine in CVD.nDM. The lowest concentrations of tyrosine and tryptophan in DM.CVD has been detected , and methionine has been detected in DM.nCVD. The amino acids alanine, glutamine, tyrosine, valine, methionine, leucine, lysine and arginine significantly increased the chances of developing DM.nCVD. For each increase in Z-score per plasma concentration of isoleucine, the chances of developing cardiovascular disease without diabetes were significantly increased.
Conclusion: The amino acids alanine, glutamine, tyrosine, valine, methionine, leucine, lysine and arginine are involved in predicting the risk of DM.nCVD and isoleucine and methionine are involved in predicting the risk of CVD.nDM.

Abstract
Background: Glycation is the non-enzymatic reaction between the carbonyl groups in sugar and free amino groups in proteins. this reaction leads to changes in structure and functions of proteins. Advanced glycation end products (AGEs) is the final stage in this process, which is highly oxidizing and destructive nature, causing many diabetic complications.
Methods: In the present investigation, the effect of fasting upon the glycation process of human Carbonic anhydrase II under physiological conditions (37 °C and pH 7.4) was studied recruiting various techniques including Ultraviolet–visible spectroscopy, fluorescence spectroscopy and CD Spectroscopy. To address this question, different samples of control carbonic anhydrase (without glucose and 3-beta-hydroxybutyrate), carbonic anhydrase with glucose, carbonic anhydrase in the presence of only 3-beta-hydroxybutyrate (BHB) and carbonic anhydrase along with glucose and 3-beta-hydroxybutyrate were incubated for 35 days under physiological conditions.
Results: The results indicate that 3-beta-hydroxybutyrate, which is greatly increased in the body during fasting, functions as an inhibitor of the glycation process and decreases the impacts of glucose binding to the protein and prevents the formation of AGEs and preserve enzyme activity.
Conclusion: Fasting can play an important role in maintaining the health of the body and eliminating the complications of the disease, with a significant increase in the production of 3-beta-hydroxybutyrate as an inhibitor of the glycation process.

Abstract
Background: The release of adipokines from adipose tissue depots plays a key role in regulating metabolic homeostasis and several other physiological processes, including diabetes, obesity, and vascular diseases. This study investigated the effect of eight weeks of high intensity interval training (HIIT) on asprosin, lipid profile and insulin resistance in type 2 diabetic male rats.
Methods: 24 male Sprague Dawley rats were randomly divided into four equal groups: control (C), control traning (C+T), diabet (D) and diabet traning (D+T). Diabetes was induced by the combined method of high fat diet and low dose strepotozocin injection. The traning group performed the HIIT program on the treadmill for eight weeks. Data were analyzed using one-way ANOVA and bonferroni post hoc test at a significance level of P<0.05.
Results: The results showed increased plasma asprosin in D group compared to C (P=0.0001) and decreased in C+T group compared to C (P=0.03) and D+T group compared to D (P=0.04). There was no significant difference in HOMA-IR between the C and C+T group (P=0.9) but decreased in D+T compared to D (P=0.0001). HDL increased in D+T group compared to the D (P=0.0001) and decreased TG and LDL (P=0.001). There was no significant difference between TG and LDL in the C group compared to the C+T, but HDL increased in C+T (P=0.01).
Conclusion: Plasma asprosin increases in rats with type 2 diabetes and HIIT can reduce the complications of diabetes by improved lipid profile and reduce asprosin and insulin resistance.

Abstract
Background: Adipogenesis is a dynamic process that leads to the phenotype of mature fat cells and plays a significant role in obesity and diabetes. The present study investigates the effect of Eight –Weeks of High-Intensity Interval Training (HIIT) and L -carnitine Consumption on the expression of BMP7 protein in visceral adipose tissue in diabetic rats.
Methods: In an experimental clinical-intervention study, 50 male Wistar rats were divided into 5 equal groups of control (C), diabetic (D), supplemental diabetic (D + LC), diabetic with exercise (D + T), supplement and exercise (D + LC + T). The training program consisted of eight weeks, 5 sessions per week (6 to 12 2-minute sessions with an intensity of 85-90% of the maximum speed). The subjects received 30 mg/kg body weight L-carnitine through drinking water. Visceral fat was extracted and the expression level of BMP7 protein was assessed using Western Blotting. Data analysis was performed by one-way ANOVA and Tukey post hoc test at a significant level of (P< 0.05).
Results: The results showed that the expression of BMP7, the adipogenesis stimulating protein, in (D + T) and (D + LC + T) groups increased significantly (P< 0.001).
Conclusion: According to the results, it seems that HIIT exercise alone and with L-carnitine Consumption is more effective in the expression of protein associated with adipogenesis expression in visceral fat. However, a clear statement requires further research in this area.
