Abstract
Hydrogen sulfide (H2S) has been extensively studied as a signal molecule in the body for the past 30 years. Researchers have conducted studies using both natural and synthetic sources of H2S, known as H2S donors, which have different characteristics in terms of how they release H2S. These donors can be inorganic salts or have various organic structures. In recent years, certain types of sulfur compounds found naturally in foods have been characterized as H2S donors and explored for their potential health benefits. These compounds are referred to as "sulfanutraceuticals," a term that combines "nutrition" and "pharmaceutical". It is used to describe products derived from food sources that offer additional health advantages. By introducing the terms "sulfaceuticals" and "sulfanutraceuticals," we categorize sulfur-containing substances based on their origin and their use in both preclinical and clinical research, as well as in dietary supplements.

Abstract
OBJECTIVE SARS-CoV-2 is a new Coronavirus identified as the cause of Coronavirus disease in 2019 (COVID-19). The epidemic spread in China and beyond its borders, involving 114 countries with more than 5 million dead. On March 11, the WHO declared the spread of SARS-CoV-2 to be a pandemic and encouraged nations to adopt harsh restrictive measures. Therefore, patients more and more often turn to dental offices only for emergencies. Healthcare professionals, including dentists, are at high infectious risk. In fact, the closeness to the oral cavity and nasopharynx and the use of drills or ultrasonic devices that cause aerosol release, make dental professions at high risk of bacterial and viral infections. The way patients are treated has changed. In fact, it should be mandatory to carry out a pre-treatment telephone triage and the use of mouthwashes to reduce bacterial load. In the current pandemic, it is necessary to adopt specific safety protocols that can protect dental operators as well as limit the spread of the virus. The purpose of this review is to present an overview on ways to reduce the risk of SARS-CoV-2 contagion in dentistry by focusing on the immediate situation as well as by looking towards the future. MATERIALS AND METHODS To reach the review purpose, we selected a series of studies using keywords "COVID-19" OR "SARS-CoV-2" in association with "dentistry" AND "safety protocols" AND "healthcare procedures" AND "individual protection dispositive" AND "air transmission" AND "droplet". We selected papers exclusively in English language, up to 1st January 2022. RESULTS During future phases of the pandemic, everywhere in the World, it is necessary to impose all dentistry team both a serological screening and the vaccination, as already established for all health staff in Italy. CONCLUSIONS For own safety, it is an important for the whole dentistry category constantly update the devices and the protocols adopted, as well as monitoring the real infectious threats, which may occur.

Abstract
Abstract
Background
Although interest in frailty has expanded among cardiology experts over the past 2 decades, its integration, as part of cardiovascular disease management, is still lacking, above all in the acute cardiac care setting. The Clinical Frailty Scale (CFS) is a brief guided tool to assess frailty in hospital settings without specialist equipment.
Purpose
Our objective was to test the performance of the CFS in an older, unselected population, admitted to an Intensive Cardiac Care Unit (ICCU) during the year 2019.
Methods
The study sample included 431 patients ≥65 years old, admitted to an ICCU of a tertiary cardiac center in Italy. The CFS ranged from “very fit: 1” to “terminally ill: 9”, but it was considered present at a score ≥5. Our primary endpoint was defined by a combination of severe complications requiring critical care and in-hospital death. The data were collected from the hospital discharge summary and the electronic chart records.
Results
158 patients (36.7%) were frail. These individuals had greater comorbidity and higher in-hospital mortality (Table 1). After a multivariable logistic regression analysis, 4 predictors were identified: signs of congestive heart failure (OR: 8.51, 95% Confidence Interval-CI: 4.63–14.6; p<0,001), systolic blood pressure (OR per 1 mmHg increasing: 0.98, 95% CI: 0.97–0.99; p<0,001), smoking habit (OR: 0.49, 95% CI: 0.22–1.11; p=0.09) and the CFS ≥5 (OR: 1.86, 95% CI: 1.08–3.23: p=0,026).
Conclusions
The CFS is a simple guided frailty tool that may enhance outcome prediction in the acute cardiac care setting. These findings merit evaluation in larger cohorts of unselected patients.

Abstract
Right ventricular (RV) involvement is frequently detected in patients presenting with acute left ventricular myocardial infarction. The ischemic right ventricle carries a dismal outcome by predisposing the heart to arrhythmic events and mechanical or hemodynamic complications. A comprehensive RV evaluation by multimodality imaging could guide clinical practice but has always been a conundrum for the imagers. Two-dimensional echocardiography is the best first-line tool due to its availability of bedside capabilities. More advanced imaging techniques provide a more comprehensive evaluation of the complex RV geometry but are mostly reserved for the post-acute setting. Three-dimensional echocardiography has improved the evaluation of RV volumes and function. The recent application of speckle-tracking echocardiography to the right ventricle appears promising, allowing the earlier detection of subtle RV dysfunction. Cardiac magnetic resonance imaging is considered the gold standard for the RV assessment. Cardiac multidetector computed tomography could be a reliable alternative. The aim of this review is to focus on the growing importance of multimodality imaging of the ischemic right ventricle and to propose a diagnostic algorithm, in order to reach a comprehensive assessment of this too frequently neglected chamber.

Abstract
Recent studies have demonstrated that the outline shapes of deciduous upper and lower second molars and the deciduous upper first molar are useful for diagnosing hominin taxa-especially Homo neanderthalensis and Homo sapiens. Building on these studies, we use geometric morphometric methods to assess the taxonomic significance of the crown outline of the lower first deciduous molar (dm1). We test whether the crown shape of the dm1 distinguishes H. neanderthalensis from H. sapiens and explore whether dm1 crown shape can be used to accurately assign individuals to taxa. Our fossil sample includes 3 early H. sapiens, 7 Upper Paleolithic H. sapiens, and 13 H. neanderthalensis individuals. Our recent human sample includes 103 individuals from Africa, Australia, Europe, South America, and South Asia. Our results indicate that H. neanderthalensis dm1s cluster fairly tightly and separate well from those of Upper Paleolithic H. sapiens. However, we also found that the range of shapes in the recent human sample completely overlaps the ranges of all fossil samples. Consequently, results of the quadratic discriminant analysis based on the first 8 principal components (PCs) representing more than 90% of the variation were mixed. Lower dm1s were correctly classified in 87.3% of the individuals; the combined H. sapiens sample had greater success (90.2%) in assigning individuals than did the H. neanderthalensis sample (61.5%). When the analysis was run removing the highly variable recent human sample, accuracy increased to 84.6% for H. neanderthalensis, and 57.1% of Upper Paleolithic H. sapiens were classified correctly by using the first 4 PCs (70.3%). We conclude that caution is warranted when assigning isolated dm1 crowns to taxa; while an assignment to H. neanderthalensis has a high probability of being correct, assignment to Upper Paleolithic H. sapiens is less certain.

Abstract
Abstract
Background
In non-valvular atrial fibrillation (AF) patients, risk stratification scores such as CHA2DS2VASc and HASBLED allow the prediction of thromboembolic and bleeding risks, respectively. However, no risk score for the prediction of AF recurrence has been yet validated.
Purpose
To evaluate the mayor anthropometric and echocardiographic determinants of AF recurrence in non-valvular paroxysmal AF patients at 1 year follow-up.
Methods
Among 395 consecutive adult patients with non valvular AF enrolled in the Neapolitan Atrial Fibrillation (NeAfi) Echo registry, 177 (F/M = 87/90, age = 66.5± 11.9 years) had paroxismal AF and underwent 1-year follow-up. Fifteen patients had AF recurrence. Anthropometric parameters and blood pressure (BP) were recorded and CHA2DS2VASc and HASBLED scores were calculated. At baseline, patients underwent a comprehensive echo-Doppler exam, including quantification of left atrial (LA) size measurements, peak atrial longitudinal strain (PALS) and left ventricular (LV) global longitudinal strain (GLS). Binary logistic regression analysis was used to establish a mathematical model of the relationship between the variables and AF recurrence. The covariates for regression analysis were chosen as potential confounding factors based on their significance in independent T test analyses for continuous variables of chi-square for dichotomous variables, or on their biological plausibility.
Results
AF recurrence was higher in male than in female patients (14.4 vs 2.3%, p = 0.008). Patients with AF recurrence had similar body mass index, systolic and diastolic BP and heart rate compared to those without. The two groups were similar for LV end-systolic and end-diastolic volumes, ejection fraction, LV mass index, diastolic indexes, pulmonary artery systolic pressure and GLS. LA diameter (p = 0.235) and PALS (p = 0.375) were also similar between the two groups, whereas LA volume index (LAVi) was greater in patients experiencing AF recurrence (45.5 ± 15.7 vs. 36.7 ± 10.4 ml/m², p = 0.003). Binomial multiple regression analysis model explained 25% (Nagelkerke R²) of the variance in AF recurrence and correctly classified 95.0% of cases. Males were 8.9 times more likely to exhibit AF recurrence than females (p = 0.04). Greater LAVi was associated with an increased likelihood of exhibiting AF recurrence (OR = 1.07, p = 0.03), whereas CHA2DS2VASc >1 in men and >2 in women, HASBLED >3 and greater LA diameter or lower PALS did not add significant information to the model.
Conclusions
Male gender and, with a lower extent, LAVi appear to be major determinants of AF recurrence in non-valvular paroxysmal AF. The quantification of PALS does not seem to add valuable information in the prediction of recurrent AF.

Abstract
Abstract
Background
The risk of cardiovascular (CV) disease in type 2 diabetes mellitus (T2DM) is highly heterogeneous and an adequate risk stratification is needed. CV risk mainly depends on concomitant risk factors, combined in the metabolic syndrome (MetS). Echocardiography is an useful tool for diagnosis of cardiac organ damage and CV risk stratification in T2DM.
Purpose
To investigate the effects of MetS on left ventricular (LV) structure and function in patients with T2DM with normal LV ejection fraction (LVEF) and without overt coronary artery disease (CAD) and heart failure symptoms/signs.
Methods
We prospectively recruited 384 consecutive, uncomplicated T2DM patients. All patients underwent clinical exam, blood sampling and complete echo-Doppler exam, including determination of 2D-echo derived global longitudinal strain (GLS). LV mass index ≥45 g/m^2.7 in women and ≥49 g/m^2.7 in men was used to characterize LV hypertrophy. LV longitudinal dysfunction was assumed for GLS < 20% in absolute values. LV diastolic dysfunction was identified according to 2016 ASE/EACVI recommendations. MetS was defined according to NCEP-ATP III criteria. Significant CAD including previous myocardial infarction, LV systolic dysfunction (= LVEF <50%), hemodinamically significant valvular heart disease, primary cardiomyopathies, permanent atrial fibrillation, glomerular filtration rate <30 ml/min and inadequate echo images were exclusion criteria. The study population was divided according to presence of MetS.
Results
66% of the patients (254/384) met the criteria for MetS diagnosis. They had comparable age and heart rate with controls. Diabetic patients with MetS had higher glycated haemoglobin (HbA1c) (7.2 ± 1.3 vs. 6.9 ± 1.0%, p = 0.023) and uric acid (5.5 ± 1.4 vs. 4.9 ± 1.3 mg/dl, p = 0.001) than those without, and lower glomerular filtration rate (69.5 ± 15.0 vs 74.0 ± 12,1 ml/min, p = 0.004). MetS patients showed a higher LV mass index (p < 0.0001) and a greater prevalence of both LV hypertrophy (31.9 vs 12.5%, p < 0.0001) and diastolic dysfunction (52.6 vs. 32.8%, p = 0.007) (Figure). T2DM patients with MetS also had lower GLS (20.6 ± 2.1 vs. 21.9 ± 2.2%, p = 0.001), with a greater prevalence of LV longitudinal dysfunction (38.2 vs. 24.7%, p = 0.049) (Figure). After adjusting for age, T2DM duration, sex, HbA1c, uric acid, LV mass index and LV diastolic dysfunction by a multiple regression analysis in the pooled population, GLS reduction was independently associated with MetS (β coefficient = -0.184, p < 0.02) and LV mass index (β= -0.94, p = 0.04).
Conclusion
In patients with T2DM, the presence of MetS induces a greater prevalence not only of LV hypertrophy and diastolic dysfunction but also of LV longitudinal deformation impairment. GLS reduction in diabetic patients is associated with MetS independently of confounders including glycemic control and diabetic duration.

Abstract
Abstract
Background
An impairment of speckle tracking derived left ventricular (LV) global longitudinal strain (GLS) has been observed in patients with bicuspid aortic valve (BAV) and referred to abnormalities of aortic elasticity properties. The impact of LV mass on myocardial deformation has still not been investigated. This issue can be now better addressed by myocardial work software, which incorporates both deformation and hemodynamic load in the analysis.
Aim of the study
To analyse the impact of both deformation and strain derived myocardial work in BAV patients with and without LV hypertrophy (LVH).
Methods
Sixty-five patients with BAV underwent a comprehensive echo exam, including speckle tracking derived calculation of GLS (in absolute value). Parameters of myocardial work such as global work index (GWI), global constructive work (GCW) global wasted work (GWW) and global work efficiency (GWE) were measured according to standardized procedures. Patients with reduced LV ejection fraction and with more than mild aortic stenosis and/or regurgitation were excluded. Other exclusion criteria included coronary artery disease, concomitant valvular heart disease, heart failure, primary cardiomyopathies, permanent and/or persistent atrial fibrillation and inadequate echo images. BAV patients were divided according to presence of LVH: 10 with LVH (LV mass index >47 g/m^2.7 in women and >50 g/m^2.7 in men) and 55 without LVH.
Results
The two groups were comparable for sex, age and heart rate whereas systolic blood pressure (p = 0.006) and pulse pressure (p = 0.002) were higher in patients with LVH, who also had higher relative diastolic wall thickness (p < 0.02). No significant difference in ejection fraction (p = 0.56), transmitral E/A ratio (p = 0.504) and E/e" (p = 0.311) was found between the two groups. GLS (19.1 ± 2.5 in LVH group and. 20.0 ± 2.4% in patients without LVH, p = 0.290), GWI (p = 0.356) and GCW (p = 0.396) did not differ significantly whereas GWW was higher (119.5 ± 72.9 vs. 72.3 ± 38.7 mmHg%, p = 0.003) and GWE lower (94.4 ± 3.0 vs. 92.2 ± 1.6%, p = 0.007) in BAV patients with LVH (Figure). In the pooled population, LV mass index was related with GWW (r = 0.26, p = 0.03) and GWE (r=-0.30, p < 0.01) but not with GLS (r=-0.22, p = 0.08). The relation between GWE and LV mass index remained significant even after adjusting for pulse pressure (partial r=-0.28, p < 0.02).
Conclusion
In patients with BAV, LVH plays a detrimental effect on LV systolic function which cannot be identified by ejection fraction and GLS assessment but is unmasked by the application of myocardial work. In presence of LVH, the wasted work of BAV patients is increased and myocardial efficiency is substantially reduced, it being negatively related to LV mass even after adjusting for a raw index of aortic stiffness such as pulse pressure.

Abstract
Abstract
Background
Left ventricular (LV) global longitudinal strain (GLS) is able to detect an early subclinical dysfunction and it has been demonstrated to be a prognosticator in arterial hypertension. Information of regional longitudinal strain (LS) pattern has not been investigated in this clinical setting.
Purpose
We analyzed regional LV patterns of LS and base-to-apex behaviour of LS in newly diagnosed and never-treated hypertensive patients (HTN) without clear-cut LV hypertrophy (LVH).
Methods
166 HTN (M/F = 107/59; age 43.9 ± 14.3 years, blood pressure [BP] = 146.5± 10.7/90.1 ± 7.5 mmHg) and a control group of 94 healthy subjects (M/F = 58/36; age 41.2 ± 15.0 years) underwent standard echo-Doppler exam, including speckle tracking quantification of regional LS and GLS (considered in absolute values). The average LS of six basal (BLS), six middle (MLS), and six apical (ALS) segments and relative regional strain ratio - RRSR = [ALS/(BLS + MLS)] - were also computed. Exclusion criteria were LVH (LV mass index ≥45 g/m^2.7 in females and ≥49 g/m^2.7 in males), diabetes mellitus, coronary artery disease, overt heart failure, hemodynamically significant valve heart disease, primary cardiomyopathies, atrial fibrillation and inadequate echo imaging.
Results
The two groups were comparable for sex, age, heart rate and LV ejection fraction (EF). Body mass index (BMI), systolic (SBP), diastolic (DBP) and mean BP (MBP) (all p < 0.0001), LV mass index (p = 0.03), relative wall thickness (RWT) (p < 0.02) and E/e’ ratio (p < 0.01) were higher, and GLS lower (21.6 ± 2.0 vs. 22.2 ± 2.1%, p < 0.02) in HTN. By analyzing regional LS, BLS (18.2 ± 2.1% vs. 19.2 ± 2.1%, p < 0.0001) and MLS (20.7 ± 2.0 vs. 21.4 ± 2.1%, p = 0.007) resulted significantly lower in HTN, without significant difference in ALS (26.0 ± 3.6 vs. 25.9 ± 3.8%, p = 0.98). Accordingly, RRSR was higher in HTN (0.67 ± 0.09 vs. 0.64 ± 0.09, p < 0.01). Even after excluding patients with LV concentric remodeling (RWT > 0.42) (n = 34), BLS (p < 0.0001) and MLS (p < 0.002) were again lower and RRSR (p < 0.01) higher in HTN than in controls. In the pooled population, BLS negatively correlated with SBP (r=-0.22), DBP (r=-0.25) and MBP (r=-0.26) (Figure) (all p < 0.0001). By a multiple linear regression analysis, after adjusting for age, sex, BMI and RWT, the association between BLS and MBP remained significant (β coefficient=-0.23, p < 0.0001), with an additional significant impact of male sex (β=-0.33, p < 0.0001) (cumulative R²=0.18, SEE = 1.9%, p < 0.0001).
Conclusions
Besides normal LV EF, GLS is lower in HTN. LS dysfunction involves basal and, with a lower extent, middle myocardial segments, with a compensation of apical segments. RRSR appears to be significantly higher in HTN. These results are even confirmed in hypertensive patients with normal LV geometry. The association of BLS and BP appears to be independent on several confounders. Regional LS pattern might be useful to detect very early LV systolic abnormalities in arterial hypertension.

Abstract
Abstract
Background
Patients with coarctation of the aorta (CoA) have proven impaired left ventricular (LV) myocardial deformation that will persist even after successful transcatheter intervention compared to normal controls. However, little is known about layer specific contraction in this clinical setting.
Purpose
To investigate multi-layer longitudinal strain in patients with repaired CoA, compared with a control group of healthy subjects.
Methods
In a case-control study, 13 CoA patients (F/M = 9/4, age = 15.1 ± 4.4 years) and 13 healthy age- and sex-matched controls, underwent a complete echocardiogram, including speckle tracking assessment for quantification of LV transmural global longitudinal strain (GLS), subendocardial longitudinal strain (LSsubendo), subepicardial longitudinal strain (LSsubepi), and myocardial longitudinal strain gradient (LSsubendo - LSsubpepi).
Results
CoA patients had similar blood pressure, heart rate, and body surface area in comparison with healthy controls. The two groups did not differ for ejection fraction and LV diastolic indices. Increased maximal gradient (>20 mmHg) in descending aorta was found in 9 (69.2%) CoA patients. In CoA population, 5 (38.5%) had LV concentric remodeling (RWT > 0.42) and 2 (15.4%) LV hypertrophy (Z score >2.0). LV mass index (92.4 ± 31.1 vs. 60.9 ± 12.5 g/m^2.7, p = 0.002), septal wall thickness (8.7 ± 2.0 vs 6.6 ± 0.9 mm p = 0.002), posterior wall thickness (8.2 ± 1.7 vs. 6.6 ± 1.4 mm, p = 0.02) and RWT (0.38 ± 0.06 vs. 0.27 ± 0.08, p < 0.001) were greater in CoA patients. By multi-layer deformation analysis, GLS (21.2 ± 1.9 vs. 22.9 ± 1.4%, p < 0.01), LSsubepi (19.3 ± 1.6 vs. 21.0 ± 1.6%, p < 0.01), LSsubendo (22.9 ± 1.8 vs. 25.4 ± 1.9%, p = 0.003) and longitudinal strain gradient (3.6 ± 1.1 vs. 4.7 ± 1.1, p < 0.02) were lower in CoA patients than in healthy controls. Separate sub-analyses in patients without LV hypertrophy, substantially confirmed the same results: GLS 20.9 ± 1.6 vs. 22.8 ± 0.9%, p = 0.004; LSsubepi 19.0 ± 1.4 vs. 21.1 ± 1.3%, p = 0.004; and LSsubendo 22.4 ± 1.2 vs. 25.3 ± 1.4%, p < 0.0001; strain gradient 3.4 ± 1.0 vs. 4.6 ± 1.1, p = 0.02. Notably, LSsubepi (18.6 ± 1.4 vs. 20.6 ± 1.0%, p = 0.03) and, with greater significance, LSsubendo (22.1 ± 1.1 vs. 24.7 ± 1.8%, p < 0.0001) were lower in CoA patients with increased aortic gradient versus those without significant gradient increase.
Conclusions
In CoA patients, layer specific strain imaging highlights an impairment of LV longitudinal deformation, which mainly involves LSsubendo and causes reduction of longitudinal strain gradient. This preferential impairment of subendocardium is particularly evident in patients with residual aortic gradient and is independent of LV hypertrophy.

Abstract
Abstract
Background
In Anderson-Fabry disease (AFD), the accumulation of glycosphingolipids in cardiomyocytes causes inflammation, hypertrophy and interstitial fibrosis which is first limited to the mid-myocardial layers, then spreads to transmural fibrosis. Speckle tracking echocardiography allows the estimation of layer-specific strain, differentiating longitudinal strain (LS) at subendocardium and subepicardium (LSsubendo and LSsubepi, respectively).
Purpose
To investigate the matching of functional and structural abnormalities in newly diagnosed, never treated AFD patients by comparing multi-layer LS and late gadolinium enhancement (LGE) cardiac magnetic resonance (CMR).
Methods
Twenty newly diagnosed, never treated AFD patients (age = 37 ± 13 years; F/M =10/10) and 20 healthy controls, matched for age and sex, underwent comprehensive evaluation of target organs and a standard echo-Doppler exam, including assessment of relative diastolic wall thickness (RWT) and left ventricular mass index (LVMI). Left ventricular hypertrophy (LVH) was defined as LVMi > 47 g/m^2.7 in women and >50 g/m^2.7 in men. Speckle tracking echocardiography derived left ventricular transmural global longitudinal strain (GLS), LSsubendo, LSsubepi and LS gradient (LSsubendo - LSsubpepi) were also determined. CMR sequences including assessment of LGE were also performed.
Results
AFD patients had normal renal function and comparable body mass index, blood pressure, heart rate, ejection fraction and diastolic indices with healthy controls. LVMi (p = 0.006) and RWT (p < 0.02) were greater in AFD patients than in controls. GLS (p = 0.006), LSsubendo (p = 0.005) and LSsubepi (p < 0.001) were lower in AFD patients. By CMR, only four patients (F/M = 3/1), 3 with LVH (75%), exhibited focal LGE, always localized in the midwall. LGE was detected at basal lateral wall in three patients and at the septal insertional points with the right ventricle in the remaining one. AFD patients with LGE had higher LVMi than those without LGE (47.2 ± 11.0 vs. 34.5 ± 11.6 g/m^2.7, p = 0.04). There was no correspondence of LGE with both regional LS and layer specific LS impairment (Figure). However, AFD patients with LGE had higher LS gradient compared to those without LGE (5.8 ± 0.65 vs. 4.8 ± 0.66, p < 0.02).
Conclusions
Treatment naïve AFD patients show a reduction of longitudinal deformation, which involves both subendocardial and subepicardial layers. Patients with LGE present higher LV mass and increased LS gradient, without a correspondence of LGE with both regional and layer specific LS impairment. Accordingly, this impairment might due to myocardial inflammation occurring in the early disease stages more than to myocardial fibrosis itself.

Abstract
Abstract
Background
Severe aortic stenosis (AS) and functional mitral regurgitation (MR) frequently coexist. There is no consensus about the optimal therapeutic strategy for patients with combined valve disease. Evidence has shown that double valve surgery is associated with high complication rates and mortality, whereas MR severity may improve after transcatheter aortic valve implantation (TAVI).
Purpose
Aim of our study was to evaluate hemodynamic parameters and cardiac function in patients with severe AS and concomitant MR undergoing TAVI.
Methods
We prospectively enrolled consecutive TAVI patients with concomitant MR. Exclusion criteria were primary cardiomyopathies, prior valve surgery, permanent atrial fibrillation and inadequate echocardiographic imaging. Echo-Doppler assessment, including global longitudinal strain (GLS) and peak atrial longitudinal strain (PALS) (absolute value), was performed before TAVI and after 1-3 months. MR grading was assessed according to quantitative methods (vena contracta and/or PISA). Changes (Δ) of the main echo parameters before and after intervention were computed. On the basis of MR grading changes, the study population was divided in two groups: no improvement in MR grading (NIMR) and improvement in MR grading (IMR).
Results
Of 49 included patients (M/F = 20/29, age 80.7 ± 5.6 years), 23 had mild MR and 26 moderate to severe MR before TAVI. After the procedure, MR grading improved in 11 (IMR) and remained stable in 38 (NIMR) patients. The two groups were comparable for sex, age, body mass index, blood pressure and heart rate. After TAVI, both groups showed an improvement in GLS (17.8 ± 4.7 to 20.1 ± 4.4%, p < 0.0001 and 16.8 ± 3.8 to 19.0 ± 3.1%, p < 0.01, in NIMR and IMR respectively) and in PALS (20.4 ± 7.4 to 24.2 ± 7.3%, p < 0.0001 in NIMR and 19.5 ± 4.5 to 26.7 ± 6.1%, p < 0.001, in NIMR and IMR respectively), without significant changes in ejection fraction (p = 0.12). Only in IMR group, a significant decrease of systolic pulmonary arterial pressure (sPAP) (45.5 ± 10.6 to 36.3 ± 6.9 mmHg, p < 0.001) and left atrial volume index (54.9 ± 14.8 to 48.9 ± 13.3 ml/m², p < 0.01) was observed after TAVI. Changes of sPAP (ΔsPAP) (9.1 ± 6.4 vs. -0.07 ± 6.7, p < 0.0001) was higher and ΔPALS (-7.2 ± 5.1 vs. -3.8 ± 4.3, p < 0.03) lower in IMR compared with NIMR group (Figure). By a multiple linear regression analysis performed in the pooled population, after adjusting for ΔPALS, Δ aortic valve area and ΔGLS, the association between ΔsPAP and MR grading improvement remained significant (beta = 0.53, p < 0.001) (cumulative R²=0.31, SEE = 6.9 mmHg, p = 0.007).
Conclusion
Afterload reduction following TAVI may induce hemodynamic changes determining also a reduction in MR severity. This mechanism implies a reduction in left atrial pressure, whose PALS is a reliable marker, and a consequent reduction of post-capillary pulmonary hypertension. The association between MR improvement and ΔsPAP reduction is independent on echocardiographic confounders.

Abstract
Abstract
Background
Overweight and obesity are related to the risk of new-onset atrial fibrillation (AF). Peak atrial longitudinal strain (PALS) is an advanced echocardiographic parameter of left atrial (LA) function with a recognized diagnostic and prognostic role in both the general population and AF.
Purpose
To investigate the impact of body mass index (BMI) on LA function by utilizing standard and advanced echocardiography in patients with non-valvular AF.
Methods
In the NeAfib-Echo registry, 395 consecutive adult patients with non-valvular AF (F/M: 175/220; mean age 70.6 ± 11 years, BMI: 27.8 ± 5.6 kg/m²) were enrolled. 215 patients (54.1%) had permanent/persistent AF (prAF) and 178 (45.9%) had paroxysmal AF (pxAF). Anthropometric parameters and blood pressure (BP) were recorded and CHA2DS2VASc score was calculated. Patients underwent a complete echo-Doppler exam, including determination of PALS and left ventricular (LV) global longitudinal strain (GLS) (both reported in absolute values). The overall population was divided according to BMI tertiles: first tertile <25.3 Kg/m² (n = 127); second tertile 25.3-29 Kg/m² (n = 137); third tertile > 29.3 Kg/m² (n = 130).
Results
No significant difference of sex prevalence, age, systolic BP and heart rate was found among the three BMI tertiles, whereas diastolic BP was higher in the third tertile (p < 0.001). CHA2DS2VASc score did not significantly differ among tertiles. In the pooled population LV mass index (LVMi) (p = 0.001) progressively increased from the first to the third tertile (p < 0.001), whereas LA volume index, LV ejection fraction (EF), GLS and E/e" ratio were not significantly different among the three groups. PALS was lower in third tertile (14.3 ± 8.2%) versus both the first (19.0 ± 11.5%) and the second tertile (17.7 ± 10.6%) (p < 0.002). In separate sub-analyses according to AF type, PALS was significantly lower in the first than the third tertile in the PxAF group (p < 0.01) but not in patients with PrAF (p = 0.158). In the pooled population PALS was significantly related with BMI (r= -0.17, p < 0.001) (Figure) but also with age, heart rate, LVMi, LV EF, GLS, E/e’ ratio and pulmonary artery systolic pressure (PAPS). By a multilinear regression analysis, after adjusting for CHA2DS2VASc score, LV mass index, LV EF, E/e’ ratio and PAPs, BMI remained independently associated with PALS (standardized β coefficient = -0.127, p < 0.02) (cumulative R² =0.41, SEE = 8.5%, p < 0.0001).
Conclusions
In patients with non valvular AF, overweight and obesity exert a detrimental effect on LA function as testified by the gradual PALS reduction with the increase of BMI tertiles. BMI is associated with PALS independently of several confounders including CHA2DS2VASc. Besides CHA2DS2VASc score, BMI could be considered as an additional factor for evaluating cardiovascular risk in non valvular AF.

Abstract
Abstract
Background
Dobutamine stress echo (DSE) is a sensitive but subjective test of inducible ischemia. Speckle tracking allows now a quantitative assessment of regional wall motion, even during DSE.
Purpose
To investigate the feasibility and accuracy of global and regional longitudinal strain during DSE to detect significant CAD.
Methods
This is a prospective, observational study, including 88 patients undergoing DSE for suspected CAD. Thirthy-three patients with negative DSE were excluded from analysis. The remaining 50 patients (82% males, mean age 66.3 ± 8.2 years) with positive DSE underwent subsequent invasive coronary angiography (CA). Besides visual regional wall motion score index (WMSI), global longitudinal strain (GLS) and regional longitudinal strain (RLS) were determined at rest, at peak stress and at early recovery by a dedicated software (Automated Function Imaging) incorporated in a quoad-screen of the echo machine and activated by automatic quantification. Obstructive CAD was defined as >70% stenosis or intermediate stenosis combined with fractional flow reserve <0.80.
Results
The feasibility of DES regional longitudinal strain was 100% (n = 50/50) in the pooled population. Fifteen patients did not show coronary stenosis whereas obstructive CAD was detected in 35 patients (12 with multi-vessel disease). Among these patients, 18 patients had left anterior descending artery (LAD) stenosis, 18 left circumflex coronary artery (LCX) stenosis and 15 right coronary artery (RCA) stenosis. GLS reduction at peak stress (k = 0.253, p = 0.037) and WMSI increase at peak stress (k = 0.217, p = 0.04) showed mild but significant agreement with CA for detecting significant coronary stenosis, whereas the agreement of GLS at recovery (k=-0.087, p = 0.518) was poor. When single lesion territory was considered, GLS at peak stress (17.4 ± 5.5 vs 20.5 ± 4.4%, p = 0.034) and LAD longitudinal strain (= average of 8 myocardial segments: middle and apical posterior septum, basal, middle and apical anterior septum, basal, middle and apical anterior wall) at peak stress showed significantly lower values in the obstructed LAD regions than the territories perfused by non-obstructed coronary arteries (17.1 ± 7.6 vs 21.6 ± 5.5% p = 0.021). Conversely, in presence of significant LCX or RCA stenosis, visual regional wall motion of LCX and RCA territories were higher at peak stress (WMSI LCX = 1.80 ± 0.65 in presence of LCX stenosis vs. 1.38 ± 0.44 in absence of stenosis, p < 0.01; WMSI RCA = 1.89 ± 0.52 in presence of RCA stenosis vs. 1.42 ± 0.42 in absence of stenosis, p = 0.002), but RLS at peak stress showed a trend to increase, without achieving the statistical significance (RLS RCA: p = 0.128, RLS LCX: p = 0.103).
Conclusion
AFI-based strain quantitative analysis appears to be highly feasible during DSE. It appears also to be more accurate than the visual wall motion for the detection of myocardial ischemia in presence of LAD while the accuracy is suboptimal in patients with LCX and RCA stenosis.

Abstract
Abstract
Background
Hyperuricemia has been reported to accelerate the occurrence and worsening of cardiovascular disease, being a risk factor for coronary heart disease and cardiac mortality. Elevated uric acid (UA) is also associated with left ventricular (LV) hypertrophy and with LV diastolic dysfunction. The effect of hyperuricemia (HU) on LV systolic function is still unclear.
Purpose
Aim of our study was to evaluate the impact of elevated UA serum levels on LV systolic function, also evaluating longitudinal deformation, in a population of hypertensive patients.
Methods
We enrolled 160 treated hypertensive patients (M/F = 104/56, age 58.2 ± 13.3 years, blood pressure = 136.7 ± 16.8/81.3 ± 10.9 mmHg), who underwent standard echo-Doppler exam, including speckle tracking quantification of global longitudinal strain (GLS, considered in absolute value). HU was defined as UA≥7 mg/dL and the study population was divided in two groups: patients with (n = 63) and without (n = 97) HU. Exclusion criteria were coronary artery disease, overt heart failure, hemodynamically significant valve heart disease, primary cardiomyopathies, permanent atrial fibrillation and inadequate echo imaging.
Results
The two groups were comparable for sex prevalence, blood pressure and heart rate. Patients with HU were older and had higher body mass index (BMI) (both p < 0.0001). Prevalence of diabetes mellitus was higher in the group of patients with HU than in patients with normal UA (69% vs. 12% p < 0.0001). Fasting glycaemia was higher (p < 0.0001) and glomerular filtration rate (GFR) lower in HU hypertensives (both p < 0.0001). LV mass index (LVMi) was higher in patients with HU (p < 0.0001). Among diastolic parameters, transmitral E/A ratio (p < 0.0001) was lower, whereas E/e’ ratio (p < 0.0001), E velocity deceleration time and left atrial volume index (both p < 0.001) were higher in HU hypertensives. GLS resulted to be lower in patients with HU (20.8 ± 1.5 vs. 22.3 ± 2.2%, p < 0.0001). LV ejection fraction, despite still in normal range values, was also slightly lower in comparison with controls (60.6 ± 4.0 vs. 62.2 ± 3.9%, p < 0.01). Serum UA levels resulted to be negatively correlated with GLS (r=-0.28, p < 0.0001) (Figure), but not with ejection fraction. By a multiple linear regression analysis performed in the pooled hypertensive population, after adjusting for age, BMI, GFR, fasting glycaemia and LVMi, the association between UA levels and GLS remained significant (standardized beta coefficient =-0.25, p < 0.01), besides the significant impact of age (beta=-0.19 , p < 0.05).
Conclusions
In hypertensive patients with multiple cardiovascular risk factors, the presence of HU is associated with LV diastolic and systolic dysfunction. Serum UA levels and GLS resulted independently associated even after adjusting for several clinical and echo confounders. Acid uric might be considered as an independent marker of early LV dysfunction, able to identify hypertensive patients at increased risk for heart failure.

Abstract
Abstract
Background
Mitral stenosis (MS) is characterized by a reduced mitral valve area (MVA) and an increased transmitral pressure gradient, with direct consequences on left atrial (LA) remodelling and pulmonary arterial systolic pressure (PASP). Post-capillary pulmonary hypertension (PH) has a main impact on the outcome in patients with MS.
Purpose
To evaluate determinants of post-capillary PH in patients with pure MS by using a combined approach of standard and advanced echocardiography.
Methods
From January 2018 to January 2019, 52 consecutive patients with MS were enrolled. Concomitant hemodynamically significant valve heart disease, primary PH, coronary artery and congenital heart diseases, primary cardiomyopathies, prosthetic valves and permanent/persistent atrial fibrillation were exclusion criteria. Twenty-three "pure" MS were selected (age: 63.9 ± 11.6 years, F/M= 17/6). Twenty-three healthy controls, matched by age and sex, were recruited as the control group. All participants underwent a complete echocardiographic examination, including determination of left ventricular ejection fraction (LVEF), speckle tracking derived global longitudinal strain (GLS, in absolute values), LA volume index (LAVi) and PASP. MS severity was assessed by continuous wave Doppler derived mean transmitral pressure gradient (MPG), pressure half time (PHT) and functional mitral valve area (MVA). Data were analysed offline by a dedicated workstation.
Results
No significant difference of body mass index, systolic and diastolic blood pressure was found between the two groups, while heart rate was higher in MR (p < 0.0001). In the pooled MS population, MPG was 5.7 ± 2.4 mmHg, PHT 127.7 ± 26.9 msec and MVA 1.76 ± 0.36 cm². Twelve patients (52.1%) had mild MS, 10 (43.5%) moderate MS and one (4.3%) severe MS. Patients with MS had larger LA volumes (LAVi = 45.0 ± 12.7 vs. 28.3 ± 7.3 ml/m², p < 0.0001), higher PASP (36.4 ± 8.9 vs. 30.4 ± 6.7 mmHg, p < 0.01), lower LVEF (58.5 ± 6.1 vs. 66.0 ± 3.5%. p < 0.0001) and lower GLS (18.8 ± 4.6 vs. 21.7 ± 2.5%, p < 0.01) than the healthy controls. By analyzing the MS group, LAVi had a significant univariate relation with MPG degree (r = 0.69, p < 0.002). PASP correlated with LAVi (r = 0.60, p = 0.003) and MPG (r = 0.51, p < 0.01) but not with PHT (r = 0.28, p = 0.54) and functional MVA (r=-0.31, p = 0.33). By a multlinear regression analysis, including heart rate, MPG, LVEF and GLS as potential determinants, LAVi (standardized beta coefficient =0.65, p= <0.02) and GLS (beta =-0.62, p = 0.03) were both independently associated with PASP degree, whereas the association of MPG and PASP was not significant (cumulative R²=0.47, SEE = 5.9 mmHg, p < 0.01) in the MS group.
Conclusions
In patients with pure MS, by using a multi-parametric echocardiographic approach, LA dilation appears to be the best predictor of post-capillary PH, independent on the magnitude of LV systolic dysfunction and valvular disease severity. Particular care should be devoted to determine LA size in this clinical setting.

Abstract
Abstract
Background
Pulmonary fibrosis (PF) is a heterogeneous group of diffuse parenchymal lung diseases, including idiopathic PF (IPF), which is the most frequent type in adults, and non-IPF. The impairment of right ventricular (RV) myocardial function of PF patients is not fully elucidated.
Purpose
To identify RV alterations in patients with interstitial PF and to evaluate possible differences between IPF and non-IPF by a combined assessment with standard and advanced echocardiography.
Methods
We enrolled 61 patients affected by interstitial PF (F/M: 16/45; age 67.9±8.1 years). 33 patients had IPF fibrosis and 28 non-IPF (bronchiolitis obliterans-organizing pneumonia and nonspecific interstitial pneumonia/fibrosis). Patients with coronary artery disease, overt heart failure, primary cardiomyopathies, other forms of diffuse parenchymal lung disease, history of pulmonary embolism and primary pulmonary hypertension were excluded. PF diagnosis was made by chest radiography, spirometry and chest high-resolution computed tomography. Lung cumulative damage was evaluated by diffusion capacity of the lung for carbon monoxide (DLco). Anthropometric parameters and blood pressure (BP) were recorded. All patients underwent a complete standard and advanced echo-Doppler exam including assessment of RV structure and function. RV global longitudinal strain (RVGLS), septal and lateral longitudinal strain (SLS and LLS respectively), were estimated by speckle tracking echocardiography (all strains were reported in absolute values).
Results
No significant difference was found in sex prevalence, systolic and diastolic BP and heart rate between the two groups, whereas IPF patients were older (65.2±8.1 vs. 70.1±7.6 years, p<0.01) than non-IPF. There was no difference in DLco between IPF and non-IPF patients. The two groups had similar left ventricular (LV) mass index, LV E/A ratio and E/e' ratio, and LV ejection fraction. RV diameters, tricuspid annulus plane systolic excursion (TAPSE) and pulmonary systolic artery pressure (PAPs) were not significantly different between the two groups, whereas IPF patients had lower RV GLS (20.2±3.1 vs. 23.0±3.6%, p=0.006), SLS (17.4±3.4 vs. 20.5±4.7%, p<0.01) and LLS (22.6±4.5 vs. 25.8±4.7%, p<0.02) compared to non-IPF patients. In the pooled population, DLco was related to RV GLS (r=0.51, p=0.004) and SLS (r=0.47, p<0.01), but not with age (p=0.121), TAPSE (p=0.532), and PAPs (p=0.875). In separate sub-analyses according to PF type, DLco was related to RVGLS in patients with IPF (r=0.52, p=0.03), but not in patients with non-IPF (r=0.41, p=0.16).
Conclusion
In patients with PF, RV systolic myocardial dysfunction is detectable by speckle tracking but not with standard echocardiography. In patients with IPF, RV dysfunction is associated with the degree of lung disease damage, as assessed by DLco.

Abstract
Our aim was to identify subclinical right ventricular (RV) alterations in systemic lupus erythematosus (SLE) by combining standard and three-dimensional echocardiography (3DE). Fifty SLE patients without concomitant cardiac disease and 50 healthy controls, matched for age and gender, were enrolled. Disease damage was evaluated by inflammatory markers and SLE damage index. All patients underwent an echo-Doppler examination with 3DE assessment of RV function, RV septal and lateral longitudinal strain. The two groups had comparable body mass index and blood pressure. RV transversal middle diameter and pulmonary arterial pressure were significantly higher in SLE compared to controls. By 3DE, RV end-systolic volume ( p = 0.037) was greater, whereas stroke volume ( p = 0.023), ejection fraction ( p < 0.0001) and septal and lateral longitudinal strain (both p < 0.0001) were lower in SLE. SLE damage index ≥ 1 was negatively associated with tricuspid annular plane systolic excursion (TAPSE) ( p < 0.002), tricuspid E/A ratio ( p = 0.003), RV ejection fraction ( p < 0.05), lateral longitudinal strain ( p < 0.0001) and septal longitudinal strain ( p = 0.04). By separate multivariate models, after adjusting for age, C reactive protein and proBNP, SLE damage index was independently associated with TAPSE ( p = 0.009) and RV lateral longitudinal strain ( p = 0.007). In conclusion, a subclinical RV systolic dysfunction is detectable in SLE by 3DE, RV lateral wall strain being a key parameter. RV dysfunction is associated with cumulative disease damage.

Abstract
OBJECTIVES The dental market moves towards high-translucency monolithic zirconia dental crowns, which are usually placed either with - or without - a thin glaze layer. The microstructural features and the mechanical performances of these materials are still controversial, as well as their susceptibility to aging. This paper aims at studying these aspects in the current generation of zirconia dental crowns showing different degrees of translucency. METHODS Four different commercial zirconia materials were investigated, including one standard 'full-strength' 3Y-TZP and three grades with improved translucency. The microstructural features (phase composition and assemblage, grain size) were carefully studied, as well as mechanical properties (biaxial bending strength and indentation toughness), translucency and aging behavior (in autoclave at 134°C). Aging was conducted on crowns with and without glaze to better represent clinical uses. RESULTS Important differences are found in terms of microstructures among the materials in terms of cubic phase content and yttria in the tetragonal phase, leading to different optical, mechanical and aging resistance properties. We show that higher cubic phase content leads to better translucency and stability in water steam, but at the expense of strength and toughness. A compromise is always inevitable between translucency and aging resistance on one side and mechanical properties on the other side. SIGNIFICANCE

Abstract
The human leukocyte antigen class I gene HLA-B27 is the strongest risk factor for ankylosing spondylitis (AS), a chronic inflammatory arthritic disorder. More recently, the Endoplasmic Reticulum Aminopeptidase (ERAP) 1 and 2 genes have been identified by genome wide association studies (GWAS) as additional susceptibility factors. In the ER, these aminopeptidases trim the peptides to a length suitable to fit into the groove of the major histocompatibility complex (MHC) class I molecules. It is noteworthy that an epistatic interaction between HLA-B27 and ERAP1, but not between HLA-B27 and ERAP2, has been highlighted. However, these observations suggest a paramount centrality for the HLA-B27 peptide repertoire that determines the natural B27 immunological function, i.e. the T cell antigen presentation and, as a by-product, elicits HLA-B27 aberrant behaviours: (i) the misfolding leading to ER stress responses and autophagy and (ii) the surface expression of homodimers acting as ligands for innate immune receptors. In this context, it has been observed that the HLA-B27 carriers, besides being prone to autoimmunity, display a far better surveillance to some viral infections. This review focuses on the ambivalent role of HLA-B27 in autoimmunity and viral protection correlating its functions to the quantitative and qualitative effects of ERAP1 and ERAP2 polymorphisms on their enzymatic activity.

Abstract
Inflammatory bowel disease (Crohn's disease (CD) and ulcerative colitis (UC)) is a multifactorial disease resulting from immune dysregulation in the gut. The underlying colitis is characterized by high levels of inflammatory cytokines, including TNFα. Biological intervention for IBD patients using anti-TNFα antibodies is often an effective therapeutic solution. However, TNFα neutralization fails to induce remission in a subgroup of IBD patients, primarily in UC patients. There is a dearth of suitable animal models representing TNFα non-responders. Here we have combined one of the best UC models currently available, namely Winnie and the TNFαKO mouse to generate a TNFα-deficient Winnie to study early onset colitis. The induced TNFα deficiency with underlying colitis does not influence general health (viability and body weight) or clinical parameters (colon weight, colon length and histological colitis) when compared with the Winnie genotype alone. The molecular characterization resulted in identification of Il1β as the major elevated cytokine during early phases of colitis. Further, in vitro functional assay using bone marrow-derived dendritic cells confirmed IL-1β as the major cytokine released in the absence of TNFα. This study has generated a successful model of colitis that remains TNFα non-responsive and has demonstrated that IL-1β expression is a major pathway for the progression of colitis in this system. These data also suggest that IL-1β can be a potential target for clinical intervention of UC patients who fail to respond to TNFα neutralization.

Abstract
The aim of this study is to evaluate the efficacy and safety of prolonged therapy with low-dose clarithromycin in patients with chronic rhinosinusitis with polyps (CRSwP) after endoscopic sinus surgery (ESS). A total of 10 patients with CRSwP were identified and subjected to bilateral ESS. In post-operative patients they were treated with nasal wash with saline solution and steroid sprays (beclomethasone). During follow-up, after 30-40 days after the operation (M = 35.4 SD = +4.33), patients reported a worsening of symptoms with onset of nasal obstruction; reduction/loss of smell; headache; onset of viscous secretions and therefore all patients continued therapy with saline nasal irrigation, topical steroid therapy and started macrolide (clarithromycin 500 mg/pill: 1 pill/day for 3 days a week for 1 month). 22-item SinoNasal Outcome Test (SNOT-22) and a score to the endoscopic evaluation (endoscopic appearance score, EAS) before and after treatment were performed to evaluate efficacy of treatment. The results of the SNOT-22 and EAS showed statistically significant improvements (p < 0.05) for some parameters such as: the need to blow nose, sneezing, hyposmia, viscous mucous secretions about the SNOT-22 and reduction of secretions and edema of the nasal mucosa about the EAS. The preliminary results of our study show that the low-dose clarithromycin for a period of 1 month can improve patient complaints with CRSwP not only through the antibacterial properties but also for the immunomodulatory characteristics.

Abstract
Introduction Chronic rhinosinusitis with nasal polyposis is a common chronic disease that often affects maxillary sinus. Endoscopic sinus surgery is the most common procedure for treating the majority of maxillary sinus lesions. Objective To demonstrate the role of canine fossa puncture during endoscopic sinus surgery procedure in patients with severe maxillary sinus disease. Methods We present 2 cases where canine fossa puncture has been performed as method to obtain a complete access to the maxillary antrum. Results According our experience, 2 cases on 296 endoscopic sinus surgery (0.6%) where antrostomy and used of angled microdebrider were not sufficient, canine fossa puncture has been performed as an alternative method to obtain a complete access to the maxillary antrum. Conclusion Although the advent of endoscopic sinus surgery, our cases support the fact that actually canine fossa puncture is a minimally invasive technique useful in selected cases.

Abstract
BACKGROUND Nociceptin/orphanin FQ (N/OFQ) and its receptor (NOP) are involved in airway hyperresponsiveness (AHR) and inflammation. However, the role of nociceptin at modulating the inflammatory immune microenvironment in asthma is still unclear. OBJECTIVE To understand the role of N/OFQ in the regulation of a Th2-like environment, we used a conventional murine model of AHR. METHODS Balb/c and CD1 mice were sensitized to ovalbumin (OVA) and treated with saline solution or N/OFQ, at days 0 and 7. A group of Balb/c mice were killed at 7 and 14 days from the first sensitization for the inflammatory profile evaluation while a group of Balb/c and CD1 mice were aerosol-challenged from day 21 to 23 with OVA and killed 24 h later for functional evaluations. RESULTS In OVA-sensitized mice, N/OFQ significantly reduced IL-4+ CD4+ T cells in lymph nodes (LN) and IL-13 in the lungs, while it induced IFN-γ increase in the lung. The efflux of dendritic cells (DCs) to the mediastinic LN and into the lung of OVA-sensitized mice was reduced in N/OFQ-treated and sensitized mice. N/OFQ reduced the expression of CD80 on DCs, indicating its ability to modulate the activation of DCs. In a less prone Th2-like environment mice strain, such as CD1 mice, N/OFQ did not modify lung resistances as observed in BALB/c mice. Finally, spectroscopic data showed the N/OFQ was able to interact onto the membrane of DCs obtained from Balb/c rather than CD1 mice, indicating its ability to modulate AHR in a Th2-like environment with a direct activity on DCs. CONCLUSIONS AND CLINICAL RELEVANCE Our data confirmed the capability of N/OFQ to modulate the immune microenvironment in the lung of Th2-biased, OVA-sensitized Balb/c mice, suggesting N/OFQ-NOP axis as a novel pharmacological tool to modulate the inflammatory immune microenvironment in asthma.

Abstract
The aim of this study is to present our management protocol of sphenopalatine artery bleeding, demonstrating that nasoendoscopic cautery (NC) was a more effective method than the nasal packing, in terms of shorter inpatient stay and reduced complications rate. We present ten posterior epistaxis not resolved by nasal packing. Tabotamp® was placed in the area of sphenopalatine foramen and/or in those parts of the posterior nasal cavity, where it was suspected that bleeding origins. In two cases, the bleeding was resolved in this way, instead eight cases needed of subperiosteal cauterization of sphenopalatine artery by Dessi bipolar forceps (MicroFrance®). 4 of these 8 patients evidenced a remarkable bleeding removing nasal packing (Hb before-nasal packing = 15 ± 0.69 versus Hb after-nasal packing = 13.3 ± 0.81; t student = 2.94; p value = 0.025). These four patients showed a deviation of the nasal septum ipsilateral to epistaxis, and according our experience, a traumatism of sphenopalatine area can be caused by Merocel® nasal packing in this condition. During follow-up, no recurrences of nasal bleeding have been observed in such patients. Nasal packing must be considered if posterior epistaxis is severe, but always taking into account the specific anatomy of patient and in particular septal spurs that can further compromise sphenopalatine artery. In our experience, the endoscopic endonasal cauterization of the sphenopalatine branches represented a safe and effective procedure.

Abstract
AIM The aim of the present microleakage study was to assess the sealing ability of nanohybrid composite crowns with different finish lines exposed to simulated mechanical periodontal treatment (SMPT). METHODS After sample size calculation (α=0.05; β=0.20; δ=1.0; σ=0.8), sixty extracted mandibular molars were divided into four groups (N.=15): G1, 90° shoulder; G2, beveled 90° shoulder; G3, 90° shoulder and SMPT; G4, beveled 90° shoulder and SMPT. Tooth preparations were carried out by means of diamond burs and Arkansas stones. The buildup of crowns was performed with a nanohybrid composite on master casts obtained after polyether impressions and crowns were cemented with self-adhesive cement. Groups G3 and G4 were subjected to the equivalent of five years of semestral mechanical periodontal scaling with Gracey curettes (2-mm long strokes, 5 N). Samples were immersed into a methylene blue supersaturated solution for 10 minutes. Microleakage was measured by stereomicroscopic observation of multiple sections of the samples and leakage data underwent statistical analysis with non-parametric tests. RESULTS Marginal microleakage was 1.53±1.27% and 17.60±12.72% of the length of the adhesive interface in G1 and G2, respectively. SMPT reduced dye penetration (P<0.001) with G3 not leaking at all and G4 leaking along the 5.58±1.84% of the adhesive interface. The bevel preparation significantly worsened the marginal seal both in control and treated crowns (P<0.001). CONCLUSION Microleakage of nanohybrid composite crowns increased by adding a bevel to a 90° shoulder preparation and diminished after SMPT.

Abstract
BACKGROUND AND PURPOSE Sphingosine-1-phosphate (S1P) has been shown to be involved in the asthmatic disease as well in preclinical mouse experimental models of this disease. The aim of this study was to understand the mechanism(s) underlying S1P effects on the lung. EXPERIMENTAL APPROACH BALB/c, mast cell-deficient and Nude mice were injected with S1P (s.c.) on days 0 and 7. Functional, molecular and cellular studies were performed. KEY RESULTS S1P administration to BALB/c mice increased airway smooth muscle reactivity, mucus production, PGD2 , IgE, IL-4 and IL-13 release. These features were associated to a higher recruitment of mast cells to the lung. Mast cell-deficient Kit (W) (-sh/) (W) (-sh) mice injected with S1P did not display airway smooth muscle hyper-reactivity. However, lung inflammation and IgE production were still present. Treatment in vivo with the anti-CD23 antibody B3B4, which blocks IgE production, inhibited both S1P-induced airway smooth muscle reactivity in vitro and lung inflammation. S1P administration to Nude mice did not elicit airway smooth muscle hyper-reactivity and lung inflammation. Naïve (untreated) mice subjected to the adoptive transfer of CD4+ T-cells harvested from S1P-treated mice presented all the features elicited by S1P in the lung. CONCLUSIONS AND IMPLICATIONS S1P triggers a cascade of events that sequentially involves T-cells, IgE and mast cells reproducing several asthma-like features. This model may represent a useful tool for defining the role of S1P in the mechanism of action of currently-used drugs as well as in the development of new therapeutic approaches for asthma-like diseases.

Abstract
BACKGROUND AND PURPOSE Hydrogen sulphide (H2S) is a gaseous mediator strongly involved in cardiovascular homeostasis, where it provokes vasodilatation. Having previously shown that H2 S contributes to testosterone-induced vasorelaxation, here we aim to uncover the mechanisms underlying this effect. EXPERIMENTAL APPROACH H2 S biosynthesis was evaluated in rat isolated aortic rings following androgen receptor (NR3C4) stimulation. Co-immunoprecipitation and surface plasmon resonance analysis were performed to investigate mechanisms involved in NR3C4 activation. KEY RESULTS Pretreatment with NR3C4 antagonist nilutamide prevented testosterone-induced increase in H2S and reduced its vasodilator effect. Androgen agonist mesterolone also increased H2S and induced vasodilatation; effects attenuated by the selective cystathionine-γ lyase (CSE) inhibitor propargylglycine. The NR3C4-multicomplex-derived heat shock protein 90 (hsp90) was also involved in this effect; its specific inhibitor geldanamycin strongly reduced testosterone-induced H2S production. Neither progesterone nor 17-β-oestradiol induced H2S release. Furthermore, we demonstrated that CSE, the main vascular H2S-synthesizing enzyme, is physically associated with the NR3C4/hsp90 complex and the generation of such a ternary system represents a key event leading to CSE activation. Finally, H2S levels in human blood collected from male healthy volunteers were higher than those in female samples. CONCLUSIONS AND IMPLICATIONS We demonstrated that selective activation of the NR3C4 is essential for H2S biosynthesis within vascular tissue, and this event is based on the formation of a ternary complex between cystathionine-γ lyase, NR3C4and hsp90. This novel molecular mechanism operating in the vasculature, corroborated by higher H2S levels in males, suggests that the L-cysteine/CSE/H2S pathway may be preferentially activated in males leading to gender-specific H2S biosynthesis.

Abstract
The ability to get and keep an erection is important to men for several reasons and the inability is known as erectile dysfunction (ED). ED has started to be accepted as an early indicator of systemic endothelial dysfunction and subsequently of cardiovascular diseases. The role of NO in endothelial relaxation and erectile function is well accepted. The discovery of NO as a small signalling gasotransmitter led to the investigation of the role of other endogenously derived gases, carbon monoxide (CO) and hydrogen sulphide (H2 S) in physiological and pathophysiological conditions. The role of NO and CO in sexual function and dysfunction has been investigated more extensively and, recently, the involvement of H2 S in erectile function has also been confirmed. In this review, we focus on the role of these three sister gasotransmitters in the physiology, pharmacology and pathophysiology of sexual function in man, specifically erectile function. We have also reviewed the role of soluble guanylyl cyclase/cGMP pathway as a common target of these gasotransmitters. Several studies have proposed alternative therapies targeting different mechanisms in addition to PDE-5 inhibition for ED treatment, since some patients do not respond to these drugs. This review highlights complementary and possible coordinated roles for these mediators and treatments targeting these gasotransmitters in erectile function/ED.
