    The ACE I/D and the ACTN-3 R577X polymorphisms are the most studied genes associated with elite athlete status, even if this association has been often conflicting. The aim of the present study was to investigate the association between the ACE and the ACTN3 genotypes and elite performance in Italian male athletes. The ACTN-3 R577X and the ACE I/D genotype distributions of 59 elite male Italian athletes practicing gymnastics (G; n = 17), 100 m-400 m running (R; n = 12), and playing soccer (S; n= 30) were compared with controls from Italian (C; n = 31) populations. For ACE distribution, athletes did not differ from controls (G, X2 = 0.37, df = 2, p = 0.82; R, X2 = 1.90, df = 2, p = 0.45; S, X2 = 1.48, df = 2, p = 0.47) and the DD genotype was at very high frequency in all groups (G = 53%, R= 50%, S = 60%, C = 45%). For ACTN-3 distribution, elite gymnasts showed a significant difference from controls (X2 = 6.57, df = 2, p = 0.03), showing an absence of XX genotype. Soccer players and runners did not differ from controls in ACTN-3 genotype distribution (R, X2 =0.43, df = 2, p = 0.80; S, X 2 = 1.25, df = 2, p = 0.53). Even if the ACE DD genotype is often positively associated with elite sprint/power athlete status, its high frequency in Italian populations eliminates the possibility of its exclusive association in Italian athletes. The results of ACTN3 genotypes suggest that RR genotype of ACTN-3 gene is a determinant of elite gymnasts status but it is not the key factor for achieving a top-level performance in soccer or track events

    Preoperative assessment of cardiovascular risk in patients undergoing noncardiac surgery: The Orion study

    In patients undergoing noncardiac surgery risk indices can estimate patients' perioperative risk of major cardiovascular complications. The indexes currently in use were derived from observational studies that are now outdated with respect to the current clinical context. We undertook a prospective, observational, cohort study to derive, validate, and compare a new risk index with established risk indices. We evaluated 7335 patients (mean age 63±13 years) who underwent noncardiac surgery. Based on prospective data analysis of 4600 patients (derivation cohort) we developed an Updated Cardiac Risk Score (UCRS), and validated the risk score on 2735 patients (validation cohort). Four variables (i.e. the UCRS) were significantly associated with the risk of a major perioperative cardiovascular events: high-risk surgery, preoperative estimate glomerular filtration rate <30 ml/min/1.73 m2, age ≥75 years, and history of heart failure. Based on the UCRS we created risk classes 1,2,3 and 4 and their corresponding 30-day risk of a major cardiovascular complication was 0.8% (95% confidence interval [CI] 0.5-1.7), 2.5 (95% CI 1.6-5.6), 8.7 (95% CI 5.2-18.9) and 27.2 (95% CI 11.8-50.3), respectively. No significant differences were found between the derivation and validation cohorts. Receiver operating characteristic (ROC) curves demonstrate a high predictive performance of the new index, with greater power to discriminate between the various classes of risk than the indexes currently used. The high predictive performance and simplicity of the UCRS make it suitable for wide-scale use in preoperative cardiac risk assessment of patients undergoing noncardiac surgery

    Prevalence and management of familial hypercholesterolemia in patients with coronary artery disease: The heredity survey

    Get PDF
    Background and aims Familial hypercholesterolemia (FH) is a genetic disorder characterized by high levels of low density lipoprotein cholesterol (LDL-C) predisposing to premature cardiovascular disease. Its prevalence varies and has been estimated around 1 in 200\u2013500. The Heredity survey evaluated the prevalence of potential FH and the therapeutic approaches among patients with established coronary artery disease (CAD) or peripheral artery disease (PAD) in which it is less well documented. Methods Data were collected in patients admitted to programs of rehabilitation and secondary prevention in Italy. Potential FH was estimated using Dutch Lipid Clinic Network (DLCN) criteria. Potential FH was defined as having a total score 65 6. Results Among the 1438 consecutive patients evaluated, the prevalence of potential FH was 3.7%. The prevalence was inversely related to age, with a putative prevalence of 1:10 in those with 8) had the highest percentages of patients after an ACS (75% vs 52.5% in the whole study population). At discharge, most patients were on high intensity statin therapy, but despite this, potential FH group still had a higher percentage of patients with LDL-C levels not at target and having a distance from the target higher than 50%. Conclusions Among patients with established coronary heart disease, the prevalence of potential FH is higher than in the general population; the results suggest that a correct identification of potential FH, especially in younger patients, may help to better manage their high cardiovascular risk

    L\u2019incoerenza del legislatore nella tutela della privacy tra IVA e diritto di seguito, Aedon, Rivista di arti e diritto on line

    The L. 85/95 requires the professional visual art market operators, the galleries among them, to implement the so called "margin scheme" in order not to disclose the amount of VAT separately from the overall price. This scheme recognizes and protects the privacy of the operator about its own commercial policy. However, the implementation of the DL 118/2006, which introduced the Artists' Resale Right (ARR), requires the dissemination of private information protected since 1995. Emerges therefore a form of inconsistency between these two set of rules, which does not contribute to the transparency of the visual art market. An investigation based on the SIAE ARR data provides an empirical support of the effect of these inconsistencie

    A Price Index for Art Market Auctions

    No full text
    This paper proposes a price index for modern andcontemporary paintings based on estimates and auctionprices. We use this index for the evaluation of theItalian art market and for comparisons with returns onother assets. During the period 1983–1994 art pricesincreased in line with inflation but returns onpaintings were lower than returns on financial assets.In the long run art prices are unrelated to financialassets prices, but a positive correlation with realestate prices emerges.
