Aim: To describe the prevalence of Peripheral Artery Disease (PAD) in a random population sample and to evaluate its relationship with Mediterranean diet and with other potential cardiovascular risk factors such as serum uric acid and pulse pressure in individuals ranged 45 to 74 years. Methods: Cross-sectional analysis of 1568 subjects (mean age 6.5 years, 43% males), randomly selected from the population. A fasting blood sample was obtained to determine glucose, lipids, and HbA1C levels. An oral glucose tolerance test was performed in non-diabetic subjects. PAD was evaluated by ankle–brachial index and/or having a prior diagnosis. Results: PAD prevalence was 3.81% (95% CI, 2.97–4.87) for all participants. In men, PAD prevalence was significantly higher than in women [5.17% (95% CI, 3.74–7.11) vs. 2.78% (95% CI, 1.89–4.07); p = 0.014]. Serum uric acid in the upper quartile was associated with the highest odds ratio (OR) of PAD (for uric acid > 6.1 mg/dl, OR = 4.31; 95% CI, 1.49–12.44). The remaining variables more strongly associated with PAD were: Heart rate >90 bpm (OR = 4.16; 95%CI, 1.62–10.65), pulse pressure in the upper quartile (≥ 54 mmHg) (OR = 3.82; 95%CI, 1.50–9.71), adherence to Mediterranean diet (OR = 2.73; 95% CI, 1.48–5.04), and former smoker status (OR = 2.04; 95%CI, 1.00–4.16). Conclusions: Our results show the existence of a low prevalence of peripheral artery disease in a population aged 45–74 years. Serum uric acid, pulse pressure and heart rate >90 bpm were strongly associated with peripheral artery disease. The direct association between Mediterranean diet and peripheral artery disease that we have found should be evaluated through a follow-up study under clinical practice conditions.

Aim: To evaluate the performance of the Finnish Diabetes Risk Score (FINDRISC) and a simplified FINDRISC score (MADRISC) in screening for undiagnosed type 2 diabetes mellitus (UT2DM) and dysglycaemia. Methods: A population-based, cross-sectional, descriptive study was carried out with participants with UT2DM, ranged between 45–74 years and lived in two districts in the north of metropolitan Madrid (Spain). The FINDRISC and MADRISC scores were evaluated using the area under the receiver operating characteristic curve method (ROC-AUC). Four different gold standards were used for UT2DM and any dysglycaemia, as follows: fasting plasma glucose (FPG), oral glucose tolerance test (OGTT), HbA1c, and OGTT or HbA1c. Dysglycaemia and UT2DM were defined according to American Diabetes Association criteria. Results: The study population comprised 1,426 participants (832 females and 594 males) with a mean age of 62 years (SD = 6.1). When HbA1c or OGTT criteria were used, the prevalence of UT2DM was 7.4% (10.4% in men and 5.2% in women; p<0.01) and the FINDRISC ROC-AUC for UT2DM was 0.72 (95% CI, 0.69–0.74). The optimal cut-off point was ≥13 (sensitivity = 63.8%, specificity = 65.1%). The ROC-AUC of MADRISC was 0.76 (95% CI, 0.72–0.81) with ≥13 as the optimal cut-off point (sensitivity = 84.8%, specificity = 54.6%). FINDRISC score ≥12 for detecting any dysglycaemia offered the best cut-off point when HbA1c alone or OGTT and HbA1c were the criteria used. Conclusions: FINDRISC proved to be a useful instrument in screening for dysglycaemia and UT2DM. In the screening of UT2DM, the simplified MADRISC performed as well as FINDRISC.

Introduction: The presence of erectile dysfunction (ED) could be a warning of vascular disease in different arterial territories., Aim: The aim of this study was to investigate the association between ED and the presence of atherosclerosis in 2 different vascular beds: carotid and lower limbs., Methods: A total of 614 volunteers between 45 and 74 years of age (mean age 61.0 years) were randomly selected from the general population. ED was assessed using the International Index of Erectile Function (IIEF-5). Ankle-brachial index (ABI) measurement and carotid atherosclerosis were evaluated by echo-Doppler., Main Outcome Measures: Mean carotid intima-media thickness (IMT), prevalence of carotid plaques, mean ABI, and prevalence of ABI < 0.9 were the main outcome measures., Results: ED was present in 373 subjects (59.7%). Mean carotid IMT was significantly higher in men with ED (0.762 ± 0.151 mm vs 0.718 ± 0.114 mm, P < .001). Also the global prevalence of carotid plaques was more frequent in men with ED (63.8% vs 44.8%, P < .001), even after adjusting by age, cardiovascular risk factors, and ongoing treatment (P = .039). Both the IMT and the prevalence of carotid plaques increased significantly with ED severity (P trend .004 and <.001, respectively). There were no significant differences between groups neither in mean ABI nor in the prevalence of subjects with ABI < 0.9. However, there was a trend to a lower ABI and a higher prevalence of ABI < 0.9 with increasing ED severity., Conclusion: In the general population, the presence of ED identifies subjects with higher atherosclerosis burden in carotid arteries but not in the lower extremities., (Copyright © 2016 International Society for Sexual Medicine.
