Abstract
Background: Oral glucose tolerance testing (OGTT) is the gold standard for the diagnosis of diabetes mellitus and impaired glucose tolerance (IGT), but is time-consuming and difficult to perform. We investigated the value of glycosylated hemoglobin (HbA1C) in screening for diabetes mellitus and IGT.
Methods: In a cross-sectional study, we measured the HBA1C levels of 497 people referred for OGTT. We calculated the sensitivity and specificity of HbA1C at 1, 2, 3 and 4 SD above the normal mean. We plotted receiver operating characteristic (ROC) curves after assigning our subjects to the diabetic, IGT, ‘diabetic+IGT’, or normal group, based on WHO criteria for OGTT.
Results: HbA1C levels (mean ± SD) in the four groups were 9.2±1.5, 8.4±1.3, 7.9±0.8 and 6.8±0.7 percent in the diabetic, diabetic+IGT, IGT and normal groups, respectively. All differences were statistically significant (p<0.0001). ROC curve analysis showed that HbA1C levels above 7.5% (mean + 1SD) gave the best combination of sensitivity and specificity for the detection of diabetes (97.53% and 73.8%), IGT (66.37 and 69.44%), and diabetes+IGT (80.22% and 86.66%).
Conclusions: An HbA1C level of >7.5% is an optimal cutoff point for diabetes screening programs.

Abstract
Background : Women with polycystic overy syndrome (PCOS) are sussceptible for developing type 2 diabetes (T2DM) and cardiovascular diseases. In view increased prevalence of T2DM in patients with PCOS and priority of prescription agents capable to decrease insulin resistances for them, It is important to diagnose PCOS in T2DM patients. The aim of this study was to evaluate the prevalence of PCOS in T2DM women.
Methods : Using ‘1990 National Institute of Child Health and Human Development Conference of PCOS’ criteria, 157 premenopausal women with T2DM were assigned into PCOS and non – PCOS groups after they were examined for the evidences of clinical PCOS. A questionnaire on reproductive history was completed and the waist circumference, weight, height and BP were measured for each participant. Biochemical tests were performed in both groups, but hormonal measurements were requested only for PCOS group.
Results : The prevalence of PCOS was high (about 8%) among subjects. Patients with PCOS had significantly lower age at the onset of diabetes, higher BMI and waist circumference. The differences in BP, serum TG, HDL, LDL, cholesterol and HbA1c were non – significant between 2 groups and insulin resistance is more.
Conclusion : PCOS is prevalent in diabetic women and Insulin resistance is more likely in those with both PCOS and T2DM resistant than whom with diabetes alone. Emphasis on reducing insulin resistance may be of benefit to achieve a better diabetes control in these patients.

Abstract
Background: Zinc-Alpha 2-Glycoprotein (ZAG) has recently been implicated in the regulation of adipose tissue metabolism due to its negative association with obesity and insulin resistance. The purpose of this study is to investigate the effect of eight weeks HIIT on level of ZAG in plasma and adipose tissue in type 2 diabetic male rats.
Methods: Twenty one male rats were divided into the three groups of sham control (healthy), control (diabetic), and interval training (diabetic with training). The training group received 8 weeks of training sessions each with 5-12 repetitions of high intensity training for 15-30 seconds at the speed of 27-34 meters per second on a treadmill followed by one minute of active rest. Twenty four hours after the training session blood and body fat samples were taken to measure ZAG levels. The data was analyzed using one-way ANOVA and Tukey’s post hock test at the significance level of 0.05 (P<0.05).
Results: There were significant differences between the sham control and the control with respect to ZAG contents in adipose tissue, which was lower in the diabetic control group (P<0.001). Moreover, significant differences in ZAG contents of adipose tissue were also observed between the sham control and the group receiving the training, with the sham control having higher ZAG contents in adipose tissue (P<0.005). The eight-week HIIT significantly increased the amount of secreted ZAG in adipose tissue compared to the control diabetic group (P=0.003). No significant differences were recorded between the groups in ZAG plasma levels.
Conclusion: The HIIT increased ZAG content in the adipose tissue of the male diabetic rats. This can reduce insulin resistance in type 2 diabetes.
