Abstract
Diabetes mellitus is the commonest endocrine-metabolic disorder during the early years of life. As many as one in five of insulin-dependent diabetics may have thyroid antibodies in their sera, which is 2-20 times higher than the general population.
Methods: Tpo-ab, Tg-ab, TSH and HbAlC were measured in 48 children and adolescents with diabetes and compared with for sex/age-matched controls. Clinical data including sex, age at onset and duration of diabetes, family history and signs and symptoms of thyroid disorders were recorded. Statistical analysis was made using SPSS software.
Results: In diabetic group, twelve patients had positive thyroid autoantibodies Tg-ab was positive in ten and Tp-ab was positive in nine and both were positive in seven patients. The prevalence of thyroid antibodies in our study was 25% and in the control group, nobody had thyroid antibodies (P=0.006). Of the twelve patients with autoimmune thyroid disorders, three had hypothyroidism.
Conclusion: The prevalence of autoimmune thyroid disorders was not influenced by sex, age, duration of diabetes or HbAlc level. On the whole, nearly one-fourth of diabetic patients had thyroid antibodies, and annual thyroid antibodies investigation for these patients is suggested.

Abstract
Background: The aim of this study was to determine the level of agreement between the impaired fasting glucose (IFG) and abnormal glucose tolerance before and after application of the new IFG definition and to evaluate the impact of adding common clinical data on this agreement.
Methods: A cross sectional population based study was carried out in an Iranian urban population which enrolled 8766 men and women over 20 years. Fasting and 2-hour plasma glucose were measured in all subjects excluding those with previously diagnosed diabetes and fasting plasma glucose ≥126 mg/dl. The diagnostic parameters and kappa coefficient between the previous and revised definitions of IFG for detecting impaired glucose tolerance (IGT) and dysglycemia (IGT and diabetes) were calculated. Logistic regression and ROC curve analysis were used to determine the independent clinical risk factors and their optimal cut-points associated with IGT and dysglycemia.
Results: After using the new criteria, sensitivity of IFG for detecting IGT or dysglycemia increased but specificity and positive likelihood ratio (LR+) decreased and the κ slightly improved (0.16 to 0.29 for IGT and 0.24 to 0.35 for dysglycemia). Adding the clinical data to the revised criteria considerably improved the agreement between IFG with IGT and dysglycemia (κ increased from 0.286 to 0.470 for IGT and from 0.354 to 0.574 for dysglycemia). This also increased the LR+ from 3.86 to 14.5 and from 4.46 to 17.4 respectively for detecting IGT or dysglycemia.
Conclusion: The new IFG definition in combination with common clinical risk factors most likely predicts IGT and dysglycemia.

Abstract
Background: There are no available reports indicating the effects of Dietary Approaches to Stop Hypertension (DASH) eating plan on insulin resistance, inflammation and oxidative stress among pregnant women with gestational diabetes mellitus (GDM) We aimed to investigate the effects of DASH diet on insulin resistance, serum hs-CRP and biomarkers of oxidative stress among pregnant women with GDM.
Methods: This randomized controlled clinical trial was performed among 32 pregnant women diagnosed with GDM at 24-28 weeks' gestation. Subjects were randomly assigned to consume either the control (n=16) or DASH diet (n=16) for 4 weeks. The DASH diet was rich in fruits, vegetables, whole grains, and low-fat dairy products and low in saturated fats, total fats, cholesterol, refined grains, and sweets, with a total of 2400 mg/d sodium. The control diet contained 40-55% of its energy as carbohydrates, 10-20% as proteins and 25-30% as total fats. Fasting blood samples were taken at baseline and after 4 weeks of intervention to measure fasting plasma glucose (FPG), serum insulin and hs-CRP, HOMA-IR, plasma total antioxidant capacity (TAC) and total glutathione levels (GSH).
Results: Consumption of DASH diet, compared to the control diet, resulted in decreased FPG (-7.62 vs. 3.68 mg/dL P=0.02), serum insulin levels (-2.62 vs. 4.32 µIU/ml, P=0.03) and HOMA-IR score (-0.8 vs. 1.1 P=0.03). Increased concentrations of plasma TAC (45.2 vs. -159.2 mmol/L P<0.0001) and GSH (108.1 vs. -150.9 µmol/L P<0.0001) were also seen in the DASH group compared with control group. We failed to find a significant difference in mean changes of serum hs-CRP levels between the two diets. Within-group comparisons revealed a significant reduction in plasma TAC and GSH levels in the control diet, while a significant rise in these biomarkers in the DASH diet.
Conclusion: In summary, consumption of DASH diet in pregnant women with GDM had beneficial effects on FPG, serum insulin levels, HOMA-IR score, plasma TAC and total GSH levels. The effects of this dietary pattern on pregnancy outcomes need to be investigated in future studies.

Abstract
Background: This study was designed to assess the effects of calcium and vitamin D supplementation on the metabolic status of pregnant women with gestational diabetes mellitus (GDM).
Methods: This randomized placebo-controlled trial was performed at maternity clinics affiliated to Kashan University of Medical Sciences, Kashan, Iran. Participants were 56 women with GDM at 24–28 weeks gestation (18 to 40 years of age). Subjects were randomly assigned to receive calcium plus vitamin D supplements or placebo. All study participants were blinded to group assignment. Individuals in the calcium–vita- min D group (n = 28) received 1,000 mg calcium per day and a 50,000 U vitamin D3 pearl twice during the study (at study baseline and on day 21 of the intervention), and those in the placebo group (n = 28) received two placebos at the mentioned times. Fasting blood samples were taken at study baseline and after 6 weeks of intervention.
Results: The study was completed by 51 participants (calcium–vitamin D n = 25, placebo n =26). However, as the analysis was based on an intention-to-treat approach, all 56 women with GDM (28 in each group) were included in the final analysis. After the administration of calcium plus vitamin D supplements, we observed a significant reduction in fasting plasma glucose (p < 0.001), serum insulin levels (p = 0.02) and HOMA-IR (p = 0.001) and a significant increase in QUICKI (p = 0.003) compared with placebo. In addition, a significant reduction in serum LDL-cholesterol (P=0.02) and total cholesterol: HDL-cholesterol ratio (p = 0.003) and a significant elevation in HDL-cholesterol levels (p = 0.01) was seen after intervention in the calcium–vitamin D group compared with placebo. In addition, calcium plus vitamin D supplementation resulted in a significant increase in GSH (p =0.03) and prevented a rise in MDA levels (p = 0.03) compared with placebo.
Conclusion: Calcium plus vitamin D supplementation in women with GDM had beneficial effects on their metabolic profile.

Abstract
Background: The role of Wnts as mediators of pancreatic development has been confirmed, and exercise training may affect this process. Therefore, the present study aimed to investigate the effect of eight weeks of resistance training and moderate-intensity training on plasma Wnt3a, Wnt4, and pancreatic beta-cell count in streptozotocin-induced diabetic rats.
Methods: Twenty-four rats were divided into four groups: healthy control, diabetic control, diabetic + moderate-intensity continuous training, and diabetic + moderate-intensity resistance training. Diabetes was induced by intravenous injection of 110 mg nicotinamide and 40 mg streptozotocin per kg of body weight. The exercise training intervention was performed for eight weeks. Plasma Wnt3a and Wnt4 were measured by the ELISA method, and the number of beta cells was assessed by hematoxylin-eosin.
Results: Data analysis showed that the number of beta cells in the exercise group increased significantly compared to the diabetic control group (P<0.05). Also, a significant change was observed in the plasma levels of Wnt3a and Wnt4 in the exercise group compared to the healthy control group (P<0.05).
Conclusion: It seems that eight weeks of moderate-intensity continuous training and eight weeks of moderate-intensity resistance training probably caused the proliferation and protection of beta cells in response to an increase in Wnt3a and a decrease in Wnt4 in the diabetic rats.

Abstract
Non-Communicable Diseases (NCDs) are the major cause of premature death and disability due to diseased globally, imposing a heavy burden on the health systems. Four main categories of NCDs are cardiovascular diseases, neoplasms, diabetes, and chronic respiratory diseases. Iran, the second greatest country in the Middle East Region, has been through an important transition period of communicable diseases toward NCDs in the last decades. One of the effective approaches to control NCDs is implementation of population-based studies and interventions, trying to reduce risk factors and incidence of NCDs through investigations in the populations. Endocrinology and Metabolism Research Institute (EMRI) and Non-Communicable Diseases Research Center (NCDRC) are the pioneers trying to study and control various NCDs during the last decades in Iran. In this review, we are going to inspect some of the major completed and ongoing projects of this research institute to highlight valuable efforts to reduce burden of NCDs in Iran, and make a successful example for national and regional public health policy makers and authorities.

Abstract
Background: Inflammation plays a critical role in the promotion of hepatocyte damage and liver fibrosis. In recent years the protective role of exercise and royal jelly (RJ), has been suggested for metabolic and inflammatory disorders. In this study, we aimed to evaluate the effects of aerobic training (AT) and RJ on pro-inflammatory markers in a rat's model of a high-fat diet (HFD).
Methods: In this experimental study, 45 male rats were randomly divided into five groups (Each group: n=9): Normal Diet (ND), High-Fat Diet (HFD), High-Fat Diet +Training (HFDT), High-Fat Diet + Royal Jelly (HFDRJ), and High-Fat Diet +Training + Royal Jelly (HFDTRJ). The supplement groups received 100 mg of royal jelly (kg/body weight) diluted in distilled water orally during the intervention period. The aerobic exercise program included treadmill running with an intensity of 50-60% oxygen consumption (VO2max), 5 days/week for 8 weeks.
Results: HFD increased hepatic NF-κB (p=0.006), TNF-α (p=0.0001) and IL-1β (p=0.0001). AT, RJ as well as the combination of AT with RJ decreased NF-κB, TNF-α and IL-1β (p≤0.05). Decrease in NF-κB, TNF-α and IL-1β were significant in HFDTRJ group compared to HFDT and HFDRJ groups (p≤0.05).
Conclusion: The combination of AT and RJ may decrease inflammatory markers and improve HFD-induced hepatic steatosis by reducing the expression of NF-κB, TNF-α, and IL-1β.
