Abstract
Background Electronic health records are becoming an increasingly valuable resource for epidemiology but their data quality needs to be quantified. We aimed to validate twenty-five types of incident cancer cases in the Information System for Research in Primary Care (SIDIAP) in Catalonia with the population-based cancer registries of Girona and Tarragona as the gold-standard. Methods We calculated the sensitivity, positive predictive values (PPV), and the time-difference between the date of diagnosis entered into the SIDIAP and into the registries. We added hospital discharge cancer diagnoses to the SIDIAP to assess sensitivity changes. Results We identified 27,046 incident cancer diagnoses in the SIDIAP from 2009–2015 among the 949,841 residents of Girona and Tarragona. The cancer types with the highest sensitivity were breast (89%, 95% CI: 88–90%), colorectal (81%, 95% CI: 80–82%), and prostate (81%, 95% CI: 80–83%). Trachea, bronchus and lung cancers had the highest PPV (76%, 95% CI: 74%-78%) followed by stomach (72%, 95% CI: 68–75%) and pancreas (71%, 95% CI: 67–75%). Most cancer diagnoses were reported with less than three months of difference between the SIDIAP and the registries. More cases were registered first in the registries than in the SIDIAP. By adding cancer diagnoses based on hospital discharge data, sensitivity increased for all cancers, especially for gallbladder and biliary tract for which the sensitivity increased by 21%. Conclusion The SIDIAP includes 76% of the cancer diagnoses in the cancer registries but includes a considerable number of cases that are not in the registries. The SIDIAP reports most of the cancer diagnoses within a three-month period difference from the date of diagnosis in the cancer registries. Our results support the use of the SIDIAP cancer diagnoses for epidemiological research when cancer is the outcome of interest. We recommend adding hospital discharge data to the SIDIAP to increase data quality, particularly for less frequent cancer types.

Differences in cardio-ankle vascular index in a general Mediterranean population depending on the presence or absence of metabolic cardiovascular risk factors. Atherosclerosis 2017; 264:29-35.

Abstract
BACKGROUND AND AIMS The main aim of this study is to describe the differences in the cardio-ankle vascular index (CAVI) in individuals with metabolic cardiovascular risk factors or a previous history of vascular diseases (WCVRF) compared to healthy individuals (free of risk factors and previous history of vascular diseases; FCVRF) in a general Mediterranean population. The secondary aim is to describe the proportion of CAVI≥9 depending on the cardiovascular risk category in both CVRF groups by sex. METHODS The study is a descriptive analysis of 2613 participants randomly selected in the Girona province (Catalonia, Spain). RESULTS CAVI mean differences between sexes and age categories in both CVRF groups followed the same pattern, the FCVRF group (men 25.2%; women 14.4%) in turn had a lower prevalence of CAVI≥9 than the WCVRF group (men 57.9%; women 51.8%). The percentage of men and women with CAVI≥9 with low risk was 13.9% and 11.3% in the FCVRF group, and 31.8% and 42.0% in the WCVRF group; with moderate risk, it was 55.8% and 10.0% in the FCVRF group and 60.3% and 49.0% in the WCVRF group. CONCLUSIONS In both sexes, FCVRF groups had a lower prevalence of CAVI≥9 as well as lower mean CAVI scores, across all 10 year-age categories from 40 to 69 years, than WCVRF groups. Moreover, CAVI≥9 was frequent in individuals with low and moderate coronary risk in the WCVRF group but also in the FCVRF group. These results suggest that CAVI assessment to detect asymptomatic arteriosclerosis could be a useful tool to improve cardiovascular risk stratification.
