RLS has an independent and significant role in sleep quality and QoL in the patients with diabetes. Neuropathy with RLS does not confer any additive burden on QoL and sleep quality of this population of patients with diabetes.

Background: Whether pre-diabetes in the absence of hypertension (HTN) or dyslipidemia (DLP) is a risk factor for occurrence of major adverse cardiovascular events (MACE) is not fully established. We investigated the effect of impaired fasting glucose (IFG) alone and in combination with HTN, DLP or both on subsequent occurrence of MACE as well as individual MACE components. Methods: This longitudinal population-based study included 11,374 inhabitants of Northeastern Iran. The participants were free of any cardiovascular disease at baseline and were followed yearly from 2010 to 2017. Cox proportional hazard models were fitted to measure the hazard of IFG alone or in combination with HTN and DLP on occurrence of MACE as the primary endpoint. Results: Four hundred thirty-seven MACE were recorded during 6.2 ± 0.1 years follow up. IFG alone compared to normal fasting glucose (NFG) was not associated with an increase in occurrence of MACE (HR, 0.87; 95% CI, 0.19-4.02; p, 0.854). However, combination of IFG and HTN (HR, 2.88; 95% CI, 2.04-4.07; p, 0.000) or HTN + DLP (HR, 2.98; 95% CI, 1.89-4.71; p, 0.000) significantly increased the risk for MACE. Moreover, IFG + DM with or without HTN, DLP, or both was also associated with an increase in the incidence of MACE. Conclusion: IFG, per se, does not appear to increase hazard of MACE. However, IFG with HTN or HTN + DLP conferred a significant hazard for MACE in an incremental manner. Moreover, IFG without HTN, adjusted for DLP, can be associated with an increase in the risk for CVD-death.

Aims To explore the predictive and explanatory factors on the incidence of cardiovascular disease and the impact of visit-to-visit variability (VVV) of risk factors on incident cardiovascular disease in people with type 2 diabetes with no history of prior cardiovascular disease. Methods We performed a historical cohort study (2008-2011) on 481 people with type 2 diabetes and no history of cardiovascular disease. Cardiovascular risk factors were assessed at baseline and repeatedly during follow-up. The predictive analysis included the variables at enrollment, and explanatory analyses were based on mean of the variables measured repeatedly. VVV of the main variables was measured using the standard deviation and coefficient of variation of the measured variables. Separate multivariate binary logistic models were constructed for each parameter with the incident cardiovascular disease. Results Mean age of the participants was 54.9 years, mean glycated hemoglobin was 56 mmol/mol, and mean blood pressure was 125/78 mmHg. Incident cardiovascular disease developed in 14.3% of the participants. The 2-h post breakfast blood glucose was associated with incident cardiovascular disease (odds ratio 1.44; confidence interval = 1.08-1.90; p = 0.01). For each 1 mmol/l increase in postprandial glucose there was a 44% increase in risk of incident cardiovascular disease. VVV of glycemic indices, blood pressure, lipids, body mass index and creatinine were not associated with occurrence of cardiovascular events. Conclusion In this population of patients with type 2 diabetes and no history of cardiovascular disease in whom other cardiovascular risk factors are within or near to the recommended targets, 2-h post breakfast blood glucose level is associated with incident cardiovascular disease.

Background Atherosclerosis is the leading cause of death in patients with diabetes. We aimed to evaluate the association between ankle-brachial index (ABI) and toe-brachial index (TBI) with carotid intima-media thickness (CIMT) in patients with type 2 diabetes (T2DM). Methods This cross sectional study included 296 patients with T2DM who met the American Diabetes Association criteria for the assessment of peripheral arterial atherosclerosis. The ABI ≤ 0.9 and TBI ≤ 0.7 were considered as abnormal values. Linear and logistic regression analyses were performed to evaluate the association between TBI/ABI and CIMT. Results Right CIMT was significantly greater in the low TBI group (p = 0.03) while, left CIMT did not show a significant difference. Each 0.1-unit decrease in TBI value was independently associated with 0.017 mm increase in the right CIMT (β ± SE; -0.017 ± 0.005, p = 0.002) and with odds of the presence of increased CIMT [odds ratio and 95% confidence interval: 1.21 (1.02, 1.44)] after adjustment with all traditional risk factors. There was not any significant association between ABI and increased CIMT. Conclusions Beyond a suitable tool for the diagnosis of peripheral artery disease in patients with T2DM, TBI can be applied for prediction of subclinical carotid atherosclerosis.
