RESUMEN
OBJECTIVES: To evaluate the external validity of the FINDRISC, DESIR and ADA risk scores for the prediction of diabetes in a Spanish population aged >45 years and to test the possible improvement of FINDRISC by adding a new variable of high risk of depression when Patient Health Questionnaire-9 (PHQ-9) questionnaire score ≥10 (FINDRISC-MOOD). DESIGN: Prospective population-based cohort study. SETTING: 10 primary healthcare centres in the north of the city of Madrid (Spain). PARTICIPANTS: A total of 1242 participants without a history of diabetes and with 2-hour oral glucose tolerance test (OGTT) plasma glucose <200 mg/dL (<11.1 mmol/L) were followed up for 7.3 years (median) using their electronic health records (EHRs) and telephone contact. PRIMARY AND SECONDARY OUTCOME MEASURES: Diabetes risk scores (FINDRISC, DESIR, ADA), PHQ-9 questionnaire and 2-hour-OGTT were measured at baseline. Incident diabetes was defined as treatment for diabetes, fasting plasma glucose ≥126 mg/dL (≥7.0 mmol/L), new EHR diagnosis or self-reported diagnosis. External validation was performed according to optimal cut-off, sensitivity, specificity and Youden Index. Comparison between diabetes risk scores, including FINDRISC-MOOD (original FINDRISC score plus five points if PHQ-9 ≥10), was measured by area under the receiver operating characteristic curve (AUROC). RESULTS: During follow-up, 104 (8.4%; 95% CI, 6.8 to 9.9) participants developed diabetes and 185 had a PHQ-9 score ≥10. The AUROC values were 0.70 (95% CI, 0.67 to 0.72) for FINDRISC-MOOD and 0.68 (95% CI, 0.65 to 0.71) for the original FINDRISC. The AUROCs for DESIR and ADA were 0.66 (95% CI, 0.63 to 0.68) and 0.66 (95% CI, 0.63 to 0.69), respectively. There were no significant differences in AUROC between FINDRISC-MOOD and the other scores. CONCLUSIONS: The results of FINDRISC-MOOD were like those of the other risk scores and do not allow it to be recommended for clinical use.

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.

OBJECTIVE: Intima-media thickness (IMT) is increased in subjects with prediabetes or newly diagnosed diabetes. However, no previous studies have evaluated the relationship between the severity of carotid atherosclerosis, assessed by the presence of carotid plaques or stenosis, and the glycemic status, assessed either by fasting glucose, an oral glucose tolerance test (OGTT) or A1C levels. METHODS: Cross-sectional analysis of 1475 subjects (mean age 62 years, 44% males), randomly selected from the population. A fasting blood sample was obtained to determine glucose, lipids, and A1C levels. An OGTT was performed in non-diabetic subjects. Carotid atherosclerosis was evaluated by echo-doppler. RESULTS: A 10.5% of the population had a previous diagnosis of diabetes. Of the 1320 non-diabetic participants, 349 (26.4%) had normal fasting glucose, normal glucose tolerance and A1C < 5.7%, and were considered controls. Prediabetes was diagnosed in 850 subjects (64.4%), and diabetes was newly diagnosed in 121 (9.2%). The prevalence of patients with carotid plaques was 34.2% in controls, 45.1% in prediabetics, 64.2% in newly diagnosed diabetics, and 72.9% in established diabetic patients. These numbers were 0.3%, 1.1%, 5.0% and 7.7% for carotid stenosis, respectively. In multivariate analysis, glycemic status remained significantly associated with the prevalence of carotid plaques after adjusting for age, sex, statin treatment, and cardiovascular risk factors. CONCLUSIONS: Glycemic status is associated with all grades of carotid atherosclerosis, from early signs, as demonstrated by the IMT, to intermediate degrees, as demonstrated by the presence of carotid plaques, to advance atherosclerosis, as established by the presence of carotid stenosis.

INTRODUCTION: The incidence of type 2 diabetes mellitus (T2DM) is increasing worldwide. When diagnosed, many patients already have organ damage or advance subclinical atherosclerosis. An early diagnosis could allow the implementation of lifestyle changes and treatment options aimed at delaying the progression of the disease and to avoid cardiovascular complications. Different scores for identifying undiagnosed diabetes have been reported, however, their performance in populations of southern Europe has not been sufficiently evaluated. The main objectives of our study are: to evaluate the screening performance and cut-off points of the main scores that identify the risk of undiagnosed T2DM and prediabetes in a Spanish population, and to develop and validate our own predictive models of undiagnosed T2DM (screening model), and future T2DM (prediction risk model) after 5-year follow-up. As a secondary objective, we will evaluate the atherosclerotic burden of the population with undiagnosed T2DM. METHODS AND ANALYSIS: Population-based prospective cohort study with baseline screening, to evaluate the performance of the FINDRISC, DANISH, DESIR, ARIC and QDScore, against the gold standard tests: Fasting plasma glucose, oral glucose tolerance and/or HbA1c. The sample size will include 1352 participants between the ages of 45 and 74â years. ANALYSIS: sensitivity, specificity, positive predictive value, negative predictive value, likelihood ratio positive, likelihood ratio negative and receiver operating characteristic curves and area under curve. Binary logistic regression for the first 700 individuals (derivation) and last 652 (validation) will be performed. All analyses will be calculated with their 95% CI; statistical significance will be p<0.05. ETHICS AND DISSEMINATION: The study protocol has been approved by the Research Ethics Committee of the Carlos III Hospital (Madrid). The score performance and predictive model will be presented in medical conferences, workshops, seminars and round table discussions. Furthermore, the predictive model will be published in a peer-reviewed medical journal to further increase the exposure of the scores.
