Bicuspid aortic valve and sports: From the echocardiographic evaluation to the eligibility for sports competition
2021
Bicuspid aortic valve (BAV) is the most common congenital heart defect in adults. Although a BAV may remain without clinical consequences for a lifetime, it can deteriorate in aortic valve stenosis and regurgitation and aortic dilatation. Unfortunately, the impact of regular training on patients with BAV and its natural course is not fully understood, although preliminary evidence suggests that the progression of valvular disease occurs primarily in an independent manner from sports practice. The current review aims to report how to perform a comprehensive echocardiographic examination in athletes with BAV and analyze the current literature on the influence of sports practice and how it imp…

The size of juxtaluminal hypoechoic area in ultrasound images of asymptomatic carotid plaques predicts the occurrence of stroke
2013
Abstract OBJECTIVE: To test the hypothesis that the size of a juxtaluminal black (hypoechoic) area (JBA) in ultrasound images of asymptomatic carotid artery plaques predicts future ipsilateral ischemic stroke. METHODS: A JBA was defined as an area of pixels with a grayscale value 10 mm(2) (P 8 mm(2)) was still significant after adjusting for other plaque features known to be associated with increased risk, including stenosis, grayscale median, presence of discrete white areas without acoustic shadowing indicating neovascularization, plaque area, and history of contralateral TIA or stroke. Plaque area and grayscale median were not significant. Using the significant variables (stenosis, discr…
Carotid plaque detection improves the predictve value of CHA2DS2-VASc score in patients with non-valvular atrial fibrilation: The ARAPACIS Study
2017
Abstract Background and aims Vascular disease (VD), as assessed by history of myocardial infarction or peripheral artery disease or aortic plaque, increases stroke risk in atrial fibrillation (AF), and is a component of risk assessment using the CHA 2 DS 2 -VASc score. We investigated if systemic atherosclerosis as detected by ultrasound carotid plaque (CP) could improve the predictive value of the CHA 2 DS 2 -VASc score. Methods We analysed data from the ARAPACIS study, an observational study including 2027 Italian patients with non-valvular AF, in whom CP was detected using Doppler Ultrasonography. Results VD was reported in 351 (17.3%) patients while CP was detected in 16.6% patients. Ad…
Factors associated with potential doping behavior in Olympic-sailing: A gender-specific analysis
2019
BACKGROUND: Olympic-sailing is not contaminated with doping, and special efforts are needed to keep this sport free of doping. The aim of this study was to evaluate factors associated with potential doping behavior (PDB) in professional Olympic sailors. METHODS: The sample of participants were professional Olympic Laser class athletes (N.=80, 39 females ; all >18 years). Data were collected through previously validated questionnaires, utilizing sociodemographic-variables, sport- related- factors, and various factors of hesitation against doping (predictors), and PDB (criterion). To calculate the associations between predictors and the criterion, gender- stratified logistic regression models…
Doppler Estimation and Correction for JANUS Underwater Communications
2020
In recent years, underwater communications have seen a growing interest pushed by marine research, oceanography, marine commercial operations, offshore oil industry and defense applications. Generally, underwater communications employ audio signals which can propagate relatively far but are also significantly affected by Doppler distortions. In fact, physical properties of the water and spatial changes due to tides, currents and waves can cause channel variations or unwanted movements of the transmitter or receiver. This study shows how to compensate for the Doppler effect in transmission employing the JANUS standard, a popular modulation scheme for underwater communication. Differently for…
Association Between Implementation of the Athlete Biological Passport and Female Elite Runners’ Performance
2020
The purpose of this research was to evaluate the performances of female middle- and long-distance runners before and after the implementation of a new antidoping strategy (the Athlete Biological Passport [ABP]) in a country accused of systematic doping. A retrospective analysis of the results of Russian National Championships from 2008 to 2017 was performed. The 8 best female performances for the 800-m, 1500-m, 3000-m steeplechase, 5000-m, and 10,000-m events from the semifinals and finals were analyzed. The yearly number of athletes fulfilling standard qualifications for international competitions was also evaluated. Overall, numbers of athletes banned for doping in 2008–2017 were calculat…
Screening the bulk properties and reducibility of Fe-doped Mn2O3 from first principles calculations
2017
Abstract Manganese oxides, particularly Mn 2 O 3 , have demonstrated great potential for oxygen carrier materials in chemical looping applications. The application of these materials in the industrial scale is hindered by thermodynamic restrictions related to the reoxidation process. This disadvantage can be overcome by doping the oxide with a guest cation. Iron is one of the most promising dopants, but the atomic-level understanding of its effects on the properties of α-Mn 2 O 3 is incomplete. Herein, we report a systematic GGA+U study of the bulk properties and reducibility of Fe x Mn 2-x O 3 (0 ≤ x ≤ 2) as a function of Fe dopant concentration. In particular, we focus on a representative…
Impiego di batteri lattici autoctoni per il miglioramento igienico-sanitario del Pecorino Siciliano DOP
2017
Il Pecorino Siciliano DOP è considerato il più antico formaggio prodotto in Sicilia e, probabilmente, d’Europa. Le citazioni storiche sulla sua antica origine risalgono al IX secolo a.C. in uno dei passi più famosi dell’odissea di Omero, quando Ulisse incontra Polifemo. In seguito, anche Aristotele e Plinio esaltano il gusto unico di questo formaggio. In particolare, proprio Plinio, nella sua opera “Naturalis Historia”, redige una carta dei formaggi nella quale vengono citati, tra i migliori pecorini,quelli provenienti da Agrigento. Fra le caratteristiche peculiari del Pecorino Siciliano DOP vanno annoverati il sapore leggermente piccante e l’incantevole profumo di pascolo. Il Pecorino Sici…
