Preclinical atherosclerosis and metabolic syndrome increase cardio- and cerebrovascular events rate: a 20-year follow up
2013
BACKGROUND: Intima-media thickness (IMT) is a validated marker of preclinical atherosclerosis and a predictor of cardiovascular events. PATIENTS: We studied a population of 529 asymptomatic patients (age 62 ± 12.8 years), divided into two groups of subjects with and without Metabolic Syndrome (MetS). METHODS: All patients, at baseline, have had a carotid ultrasound evaluation and classified in two subgroups: the first one without atherosclerotic lesions and the second one with preclinical atherosclerosis (increased IMT or asymptomatic carotid plaque). Cardiovascular endpoints were investigated in a 20-years follow-up. RESULTS: There were 242 cardiovascular events: 144 among patients with Me…
Liraglutide improves metabolic parameters and carotid intima-media thickness in diabetic patients with the metabolic syndrome: an 18-month prospectiv…
2016
Abstract Background Liraglutide, a GLP-1 analogue, exerts several beneficial non-glycemic effects in patients with type-2 diabetes (T2DM), such as those on body weight, blood pressure, plasma lipids and inflammation markers. However, the effects of liraglutide on cardiovascular (CV) risk markers in subjects with the metabolic syndrome (MetS) are still largely unknown. We herein explored its effects on various cardio-metabolic risk markers of the MetS in subjects with T2DM. Methods We performed an 18-month prospective, real-world study. All subjects had T2DM and the MetS based on the AHA/NHLBI criteria. Subjects with a history of a major CV event were excluded. One hundred-twenty-one subject…
Relationship Between Carotid Atherosclerosis and Pulse Pressure with Renal Hemodynamics in Hypertensive Patients.
2015
BACKGROUND Structural atherosclerotic damage, arterial stiffness, pulse pressure (PP), and renal hemodynamics may interact and influence each other. Renal resistance index (RRI) appears as a good indicator of systemic vascular changes. The aim of our study was to assess the independent relationships of carotid intima-media thickness (cIMT), aortic pulse wave velocity (aPWV), and peripheral PP with RRI in hypertensives with various degrees of renal function. METHODS We enrolled 463 hypertensive patients (30-70 years) with normal renal function (group 0; n = 280) and with chronic kidney disease (groups I-V; n = 183). All subjects underwent ultrasonographic examination of intrarenal and caroti…
Early Vascular Aging in Normotensive Patients With Systemic Lupus Erythematosus
2015
Connective tissue diseases, like systemic lupus erythematosus (SLE), are associated with early and accelerated atherosclerosis. Recently, the concept of “early vascular aging” (EVA) has been more widely accepted. Aortic stiffness is one of the important markers of EVA. We evaluated EVA and subclinical atherosclerosis, by measuring aortic pulse wave velocity (aPWV) and carotid intima–media thickness (cIMT), in 50 normotensive patients with SLE (mean age: 39 ± 12 years). We compared these participants with 50 age- and sex-matched patients with essential hypertension (EH) and 20 healthy controls. Each participant underwent 24-hour ambulatory blood pressure monitoring (ABPM), aPWV, and cIMT me…
Changes in ultrasound-assessed carotid intima-media thickness and plaque with a Mediterranean diet: a substudy of the PREDIMED trial.
2014
OBJECTIVE - : The Prevención con Dieta Mediterránea (PREDIMED) trial showed that a Mediterranean diet (MedDiet) supplemented with either extra virgin olive oil or 30 g/d of mixed nuts reduced incident cardiovascular events compared with a control (low fat) diet. The mechanisms of cardiovascular protection afforded by MedDiets remain to be uncovered. We assessed the effect of both supplemented MedDiets on internal carotid intima-media thickness (ICA-IMT) and plaque height, the ultrasound features that best predict future cardiovascular events, in subjects at high cardiovascular risk. APPROACH AND RESULTS - : In a PREDIMED subcohort (n=175), plaque height and carotid IMT of 3 prespecified seg…
Metabolic syndrome (MetS) predicts cardio and cerebrovascular events in a twenty years follow-up. A prospective study.
2012
BACKGROUND AND PURPOSE: Metabolic syndrome (MetS) is a cluster of cardiovascular risk factors, considered as emerging and promoting atherosclerosis. This study aimed at the evaluation of the influence of MetS on the prediction of cerebro and cardiovascular events during a 20 years follow-up period in an asymptomatic population of middle-aged subjects. METHODS: We evaluated 529 asymptomatic persons through a prospective study. Study population was divided into two subgroups: patients with and without MetS. Echo-color-Doppler was used in order to assess the presence of subclinical atherosclerosis. A 20 years follow-up study was carried out in order to estimate the incidence of cerebro and car…
Markers of inflammation are strong predictors of subclinical and clinical atherosclerosis in women with hypertension
2008
Cardiovascular diseases in women still rises and remains their leading cause of death in most developed countries; yet we have less sex-specific data in women than in men as a result of lower enrollment in clinical trials and low rates of sex-specific reporting. The aim of our study was to evaluate in hypertensive postmenopausal women the potential predictive role of markers of inflammation, for example, fibrinogen and C-reactive protein (CRP), on subclinical and clinical atherosclerosis, beyond that of the other established cardiovascular risk factors. We studied 127 asymptomatic hypertensive postmenopausal women with different degrees of carotid intima–media thickness, as examined by the …
Moduli DSSC integrati nel vetromattone per la costruzione di pannelli traslucidi fotovoltaici multifunzionali
2012
La proposta illustrerà i primi risultati ottenuti nell’ambito di una ricerca, tutt’ora in corso presso il Dipartimento di Architettura dell’Università degli Studi di Palermo, finalizzata ad indagare le problematiche connesse all’integrazione del vetromattone con sistemi di produzione di energia rinnovabile, in particolare, di terza generazione (DSC-Dye Syntetized solar cell - celle fotovoltaiche organiche/ibride). I principali campi di investigazione che si illustreranno saranno connessi alle: tecniche ed i processi di deposizione delle celle sul vetromattone per la costruzione dei moduli, alla scelta del loro migliore posizionamento ed all’analisi delle ricadute, in termini di valutazione …
Influence of resin cement shade on the color and translucency of zirconia crowns
2020
Background Zirconia crowns are highly attractive for clinicians, although have poor translucency when used as single restorations, in addition to unknown effect of resin cement shade on final cemented crown shade. This study aimed to assess effect of resin cement opacity on color replication potential of different zirconia frameworks with target tooth color, in addition to different zirconia crowns translucency evaluation. Material and methods Twenty-four zirconia crown restorations were fabricated to restore single central maxillary incisor for 8 patients, divided into 3 groups according to color and type of zirconia used (white Zr core, colored Zr core and monolithic HT Zrcowns). Each gro…
Piano col colore! Mezzo secolo di contraffazioni nei centri storici
2010
The transformation dynamics of the ancient towns are completely changing the urban landscape of the historical countries in Italy in the last fifty years. The most superficial part of material constitutes the image of the architectures and plays a meaningful role in the perception of the historical districts that still characterize the contemporary city, but the aptitude for destroying architectural finishes and deleting superficial patina involves therefore to alter the character of the old towns irreversibly. It had to be obvious it would have been essential to conserve the authentic materials and signs of time that denote the historical authenticity of monuments, but new surfaces of plas…
