Multicenter Study Comparative Study Observational Study
COPD patients with and without metabolic syndrome: clinical and functional differences.
Chronic obstructive pulmonary disease (COPD) and the metabolic syndrome (MetS) are considered public health challenges of the 21st century. The coexistence of MetS in COPD patients and any clinical differences between COPD patients with and without MetS have not been extensively studied. We aimed to describe the clinical characteristics of patients with MetS and COPD. ⋯ They had been hospitalized more frequently for any cause but not for COPD. In multivariate analysis, the presence of MetS was independently associated with greater FEV1, inhaled steroids use, osteoporosis, diabetes, and heart failure. MetS is a frequent condition in COPD patients, and it is associated with greater FEV1, more dyspnea, and more comorbidities.

Comparative Study
Standardised pre-competitive screening of athletes in some European and African countries: the SMILE study.
Most of the available data on the cardiovascular screening of athletes come from Italy, with fewer records being available outside of Italy and for non-Caucasian populations. The goals of the SMILE project (Sport Medicine Intervention to save Lives through ECG) are to evaluate the usefulness of 12-lead ECGs for the detection of cardiac diseases in athletes from three European countries and one African country and to estimate how many second-level examinations are needed subsequent to the initial screening in order to classify athletes with abnormal characteristics. A digital network consisting of Sport Centres and second and third opinion centres was set up in Greece, Germany, France and Algeria. ⋯ Our data confirmed the noteworthy value of 12-lead resting ECGs as compared with other first-level evaluations, especially in athletes with asymptomatic cardiac diseases. Its value seems to have been even higher in Algeria than in the European countries. The establishment of a digital network of Sport Centres for second/third opinions in conjunction with the use of standard digital data input seems to be a valuable means for increasing the effectiveness of screening.

The aim of this study was to investigate influence of traditional cardiovascular risk factors (CVRF) and subclinical atherosclerosis (ATS) burden on early stages of abdominal aortic diameter (AAD) widening among adults. 2,052 consecutive patients (P) (39 % women), mean age 52 ± 13 years, were prospectively screened for CVRF, ATS, and AAD. B-mode ultrasound was used to evaluate the largest AAD and to detect carotid and femoral atherosclerotic plaques. Mean AAD was 15.2 ± 2.8 mm. ⋯ These factors did not account for more than 30 % of interaction (R² = 0.30, p = 0.001). Furthermore, despite a large proportion of patients with high number of CVRF, and subclinical ATS, rate of patients with AAD ≥25 mm was low (1 %) and scattered regardless their CHD risk score or ATS burden. In conclusion, these results suggest that although some traditional CVRF and presence of ATS are associated with early stages of EAAD, other determinants still need to be identified for a better understanding of abdominal aortic aneurysm pathogenesis.

Reportedly, patients with scleroderma-related pulmonary hypertension (SSc-PAH) respond poorly to new vasoactive drugs (NVD). Forty-nine SSc-PAH patients underwent right heart catheterization (RHC) and, according to NVD availability, divided as follows: Group 1 (n = 23, from 1999 to 2004, poor availability), and Group 2 (n = 26, from 2005 to 2010, good availability). Before diagnostic RHC, NVD had been given to 30 % of the patients in Group 1, and 58 % of those in Group 2 (p = 0.049). ⋯ A value of DLco <7.2 mL/mmHg/min was associated with a hazard ratio (HR) of 5.3 (p < 0.001); for SvO2 <63.8 %, the HR was 3.7 (p < 0.01). NVD have beneficial effects in patients with SSc-PAH. Both DLco and SvO2 are predictors of survival and may assist in planning treatment.
