- Abstract
The noncovalent interaction energy as a function of the core extension in double-walled carbon nanotubes (DWCNT) was accurately calculated in the frame of density functional theory, considering dispersion correction and without resorting to adjustable parameters. A linear correlation between the change of the noncovalent energy and core displacement was established for the first time through a pure quantum mechanics approach; hence, the force needed to pull out the DWCNT core was accurately calculated. This force was found to be in good agreement with experimental values reported in the literature. Furthermore, the effect of the DWCNT edges was considered in the calculation of the potential energy profile, and the frequency, associated with the oscillation of core inlet, was calculated for the first time through a quantum approach. This frequency falls in the low infrared region, and it depends on the chemical nature of the oscillator edges. The work highlights that the noncovalent H···π interaction controls the inner shell oscillation and it should be considered, beyond the stacking between inner and outer walls, as a driving force for the activation of the telescopic process. As a result, this noncovalent interaction can be tuned for the design of nano-dynamometers with well-defined force constants.

- Abstract
Noncompact left ventricle is a rare congenital cardiomyopathy characterized by numerous ventricular trabeculae separated by deep intertrabecular recesses. It can occur in isolation or in association with neuromuscular disorders and congenital heart defects. The cause is not known but it is thought to be due to the arrest of the normal maturation process of the myocardium. Among the responsible mutations are taffazzine, ZASP and distrobrevin. It can manifest as left ventricular dilatation and dysfunction, arrhythmias, thromboembolic events, and sepsis. The echocardiogram is the investigation of first choice. Magnetic resonance allows you to more precisely distinguish compact and non–compact layers, thrombi and myocardial fibrosis.

- Abstract
Background and Aim: 25-hydroxyvitamin D deficiency represents a widespread social problem but also an emerging risk factor for cardiovascular disease. Genetic variants of the Vitamin D Binding Protein (VDBP), the main transporter of vitamin D in the bloodstream, have been shown to account for a significant variability in the levels and systemic effects of vitamin D. We investigated whether the single nucleotide polymorphisms, rs7041 and rs4588, of VDBP are associated to the prevalence and extent of coronary artery disease.Methods and Results: A consecutive cohort of patients undergoing coronary angiography in a single centre were included. Significant CAD was defined as at least 1 stenosis >50%, severe CAD for as left main and/or three-vessel disease. VDBP genetic status was assessed by polymerase chain reaction and restriction fragment length polymorphism technique. We included 1080 patients, 57% carried the mutated G allele of rs7041, whereas 22% carried the A allele of rs4588. Higher levels of C- reactive protein were observed in the carriers of G allele of rs7041 (p = 0.02), whereas 25-hydroxyvitamin D levels were similar across groups. A higher prevalence of lesions in the left anterior descending artery and a longer lesion length were observed in "A" carriers for rs4588 (p = 0.04 and p = 0.03, respectively). On the contrary, a higher prevalence of bifurcation lesions and chronic occlusions was observed in G carriers (p = 0.002 and p = 0.01 respectively). Both polymorphisms of VDBP did not affect the prevalence of CAD (rs7041: 79.1% TT vs 80.3% TG vs 78.5% GG, p = 0.81; rs4588 = 80.3% CC vs 78.5% AC + AA, p = 0.49) and severe CAD, (rs7041: 31.1% TT % vs 31.3% TG vs 30.6% GG, p = 0.88; rs4588: 32.2% CC vs 29.3% AC + AA, p = 0.31). Results were confirmed at multivariate analysis, for both rs7041 and rs4588. However, when including the levels of 25-hydroxyvitamin D in the multivariate model, we observed that 25(OH)D status and not genetic variants of VDBP were significantly associated with CAD (25-hydroxyvitamin D OR [95% CI] = 0.99 [0.97-1.0], p = 0.05; rs7041 TG: OR [95% CI] = 1.26 [0.73-2.19], p = 0.41; rs7041 GG: OR [95% CI] = 1.25 [0.82-1.91], p = 0.30; rs4588 AC + AA: OR [95% CI] = 0.76 [0.51-1.13], p = 0.18).Conclusion: This study showed in a large cohort of patients undergoing coronary angiography, that the polymorphisms rs7041 and rs4588 of VDBP are not associated with the levels of 25-hydroxyvitamin D nor with the prevalence and extent of CAD. In fact, 25-hydroxyvitamin D levels but not VDBP genetic status independently predicted the occurrence of coronary lesions at angiography. [ABSTRACT FROM AUTHOR]- Published

Curcio, S., Petrosino, F., Morrone, M., and De Luca, G.
- Abstract
In the present paper, an improved multiscale modeling aimed at describing membrane fouling in the UltraFiltration (UF) process was proposed. Some of the authors of this work previously published a multiscale approach to simulate ultrafiltration of Bovine Serum Albumin (BSA) aqueous solutions. However, the noncovalent interactions between proteins and the membrane surface were not taken into account in the previous formulation. Herein, the proteins-surface interactions were accurately computed by first-principle-based calculations considering also the effect of pH. Both the effective surface of polysulfone (PSU) and the first layer of proteins adsorbed on the membrane surface were accurately modeled. Different from the previous work, the equilibrium distance between proteins was calculated and imposed as lower bound to the protein–protein distances in the compact deposit accumulated on the membrane surface. The computed BSA surface charges were used to estimate the protein potential and the charge density, both necessary to formulate a forces balance at microscopic scale. The protein surface potential was compared with Z-potential measurements of BSA aqueous solution, and a remarkable agreement was found. Finally, the overall additional resistance, as due to both the compact and loose layers of the deposit, was computed, thus allowing the final transition to a macroscopic scale, where an unsteady-state mass transfer model was formulated to describe the behavior of a typical dead-end UF process. A good agreement between simulated and experimental permeate flux decays was observed.

- Abstract
In high-Tcsuperconductors the magnetic and electronic properties are determined by the probability that valence electrons jump virtually from site to site in the CuO2planes, a mechanism opposed by on-site Coulomb repulsion and favoured by hopping integrals. The spatial extent of the latter is related to transport properties, including superconductivity, and to the dispersion relation of spin excitations (magnons). Here, for three antiferromagnetic parent compounds (single-layer Bi2Sr0.9La1.1CuO6+δ, double-layer Nd1.2Ba1.8Cu3O6and infinite-layer CaCuO2) differing by the number of apical atoms, we compare the magnetic spectra measured by resonant inelastic X-ray scattering over a significant portion of the reciprocal space and with unprecedented accuracy. We observe that the absence of apical oxygens increases the in-plane hopping range and, in CaCuO2, it leads to a genuine three-dimensional (3D) exchange-bond network. These results establish a corresponding relation between the exchange interactions and the crystal structure, and provide fresh insight into the materials dependence of the superconducting transition temperature.

- Abstract
Background and Aims: New antithrombotic therapies have significantly improved the outcomes of patients with acute coronary syndrome (ACS), where the introduction of ticagrelor has provided the greatest mortality benefits. However, ticagrelor treatment has been associated with a potential increase in the serum uric acid (SUA) levels, which may influence endothelial dysfunction and prothrombotic status, thereby affecting the risk of acute cardiovascular events in patients requiring dual antiplatelet therapy (DAPT). The present study aimed to compare the impact of antiplatelet agents such as ticagrelor or clopidogrel on SUA levels and their effect on platelet reactivity.Methods and Results: We included patients admitted for ACS or elective percutaneous coronary intervention (PCI) and discharged with ASA (acetylsalicylic acid; 100-160 mg) and clopidogrel (75 mg) or ticagrelor (90 mg twice a day). Chemistry was assessed at admission (baseline) and after a 30-90-day period of DAPT (together with platelet reactivity). The absolute and percentage variations of SUA after DAPT introduction were considered. Multiple-electrode aggregometry was used to assess platelet function. A total of 378 patients were enrolled, with 145 treated with aspirin and clopidogrel (AC) and 233 with aspirin and ticagrelor (AT). The AC patients were older (p = 0.003) and more often showed elective PCI as an indication to DAPT (<0.001); they received chronic therapy with ARB (angiotensin II receptor blocker; p = 0.001), nitrates (p = 0.044), CCB (calcium channel blocker; p = 0.005) and diuretics (p = 0.044). The AT patients displayed a higher percentage of ACS diagnosis (p < 0.001) and received chronic therapy with ACE (angiotensin-converting enzyme) inhibitors (p = 0.001), beta blockers (p = 0.001) and statins (p = 0.013). The AC patients displayed higher platelet reactivity at COL (collagen) test, ASPI test and ADP (adenosine diphosphate) test (p = 0.03, 0.001 and <0.001, respectively) and a higher percentage of HRPR (high residual platelet reactivity) in the ADP test (p = 0.001). No difference was found in the baseline uric acid and creatinine levels between AC and AT patients. At 30-90 days, a significant absolute and percentage increase in the SUA levels was found in AT as compared to AC patients (0.204 mg/dl vs. -0.165 mg/dl, p = 0.034; 6.26% vs. -0.005%, p = 0.018, respectively). Results were not influenced by variations in renal function. At multivariate analysis, in fact, ticagrelor therapy emerged as an independent predictor of increase in the uric acid levels (odds ratio (OR; 95% confidence interval (CI)) = 2.79 (1.66-4.67), p < 0.001). However, the variation in the SUA levels did not affect platelet reactivity or HRPR in both AC and AT patients.Conclusion: An increase in the SUA levels at 30-90 days was observed in patients receiving chronic DAPT with ticagrelor, but not clopidogrel treatment. However, the changes in the SUA levels do not influence platelet aggregation. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Background and Aim: High residual platelet reactivity (HRPR) is still an important challenge, despite the advent of new potent ADP-antagonists. Therefore it is of extreme importance to identify factors that can influence platelet activation. Serum uric acid (SUA) has been largely addressed in the past as a possible risk factor for coronary artery disease, with a possible association with platelets hyperreactivity. So far no studies have assessed the role of serum uric acid on the response to dual antiplatelet therapy. Therefore, the aim of our study was to evaluate the impact of uric acid levels on platelet function in patients treated with dual antiplatelet therapy (DAPT) with clopidogrel or ticagrelor.Methods and Results: We scheduled for platelet function assessment at 30-90 days post-discharge patients treated with DAPT (ASA + clopidogrel or ticagrelor) for an ACS or elective percutaneous coronary intervention (PCI). Platelet function was assessed by whole blood impedance aggregometry (Multiplate(®)-Roche Diagnostics AG), HRPR was considered for ASPI test >862 AU(∗)min (for ASA) and ADP test values ≥417 AU* min (for ADP-antagonists).Results: We included a total of 493 patients (262 were on ASA and clopidogrel and 231 on ASA and ticagrelor). Patients were divided according to quartiles of serum uric acid levels measured at the time of platelet aggregation assessment (Group 1 <4.6 mg/dL, n = 114; Group 2, 4.7-5.8 mg/dL, n = 133; Group 3, 5.9-6.8 mg/dL, n = 124; Group 4, >6.9, n = 122). Patients with higher uric acid levels were older, more often smokers, with history of hypertension and previous coronary artery bypass surgery and renal failure and were more often on therapy with diuretics at admission. Patients with higher SUA had higher triglycerides and fibrinogen. Uric acid levels did not influence ASPI, COL, TRAP and ADP tests. High residual platelet reactivity (HRPR) was observed in 1.5% of patients treated with ASA, with no difference according to SUA quartiles (p = 0.60), confirmed at multivariate analysis after correction for baseline confounders (adjusted OR[95%CI] = 1.05 [0.44-2.52], p = 0.90). HRPR for ADP-antagonists was observed in 23.6% of patients, with no difference according to SUA quartiles (p = 0.47); this result was confirmed also after correction for baseline confounders (adjusted OR[95%CI] = 1.04 [0.84-1.28], p = 0.73). Moreover, no association was found between HRPR and uric acid levels both among patients treated with clopidogrel (p = 0.35) or ticagrelor (p = 0.74), that was confirmed after correction for baseline confounding factors (adjusted OR[95%CI] = 1.18 [0.90-1.55], p = 0.23) and (adjusted OR[95%CI] = 0.96 [0.63-1.47], p = 0.85). The absence of association between SUA and platelet reactivity was confirmed at linear regression analysis both with clopidogrel (r = 0.03, p = 0.55) or ticagrelor (r = -0.01, p = 0.85).Conclusion: This is the first large study showing that in patients receiving DAPT, uric acid levels do not influence response to ticagrelor and clopidogrel or the effectiveness of ASA.

- Abstract
GINGER (Gyroscopes IN General Relativity) is a project aiming at measuring the Lense-Thirring effect, at 1% level, with an experiment on earth. It is based on an array of ring-lasers, which are the most sensitive inertial sensors to measure the rotation rate of the Earth. The GINGER project is still under discussion; the experiment G-GranSasso is an R&Dexperiment financed by INFN Group II, it is studying the key points of GINGER and at the same time developing prototypes. In the following the signal coming out of a ring-laser and the present sensitivity are described.The prototypes GP2 and GINGERino and the preliminary results are reported. This project is inter-disciplinary since ring-lasers provide informations for the fast variation of the earth rotation rate, they are used for the rotational seismology and for top sensitivity angle metrology.

- Abstract
Autologous hematopoietic stem cell transplantation (aHSCT) is a promising therapy for multiple sclerosis (MS), which has mainly been used in adults. The purpose of this study was to investigate efficacy and adverse events of aHSCT in the treatment of children with MS using data from the European Society for Blood and Marrow Transplantation registry. Twenty-one patients with a median follow-up time of 2.8 years could be identified. PFS at 3 years was 100%, 16 patients improved in expanded disability status scale score and only 2 patients experienced a clinical relapse. The procedure was generally well tolerated and only two instances of severe transplant-related toxicity were recorded. There was no treatment-related mortality, although one patient needed intensive care. aHSCT may be a therapeutic option for children with disease that does not respond to standard care.

- Abstract
It is now known that the Covid19 infection can cause myocardial inflammatory damage. Several studies have shown that the echocardiographic parameter of the global longitudinal strain (GLS) was reduced compared to the general population even in paucisymptomatic patients. A young competitive athlete came to our observation for the diagnostic investigations before returning to competitive practice (return to play protocol) after Sars–Cov2 infection. The electrocardiogram did not show significant abnormalities as well as spirometry examination. Negative inflammation indexes and markers of myocardial damage were observed. The cycloergometer test showed no signs of myocardial distress, rapid chronotropic increase and dyspnea at 100W work load. HolterECG was performed showing 830 isolated ventricular ectopic beats. Echocardiographic examination showed preserved left ventricular systolic function (FEVS 59% – Simpson method) with a moderate reduction of GLS parameter –16,9%. The cardiopulmonary exercise test (CPET) showed an early anaerobic threshold and a normal pVO2max but not in line with the presumed range for a top–level athlete. Putting together the symptoms described, the CPET data and GLS parameter, despite the negative first–level investigations he underwent MRI that documented a myocardial edema in the mid–basal region of inferior and inferolateral walls of the left ventricle. Suitability for competitive practice was blocked, a gradual physical readaptation path was started and therapy with low–dose bisoprolol was set. An important clinical improvement is reported at the 6–month follow–up with evidence of normalization of the GLS parameter –23%. The CPET howed a realignment of the HR/VCO2 curve with a late threshold and increment of pVO2max. The 6–month control MRI examination showed almost no signs of myocardial inflammation and so the patient was made suitable for returning to competitive sport. In our case first–level investigations did not support any hypothesis of myocardial inflammation. The presence of stress symptoms confirmed by CPET data but especially the reduction of GLS parameter led to a deepening investigation with MRI that confirmed the presence of myocardial inflammatory lesion. Our case suggests that within a “return to play” protocol for athletes with recent SarsCov2 infection, the analysis of left ventricular systolic function by GLS may represent an additional useful element to be considered in support of standard investigations.

16. P167 CARDIAC ARREST IN SUSPECTED LONG QT: APPROACH TO ARRHYTHMIC MITRAL VALVE PROLAPSE
- Author

Bevere, E, Mastroianno, S, Greco, A, Brunetti, N, Salvatori, M, Potenza, D, De Luca, G, and Di Stolfo, G
- Abstract
Mitral valve prolapse is a common condition. It affects 1–3% of the population. Clinical manifestations range from the absence of symptoms to sudden cardiac death. The arrhythmogenic mechanism is related to fibrotic changes in myocardial posterior caused by valve prolapse. ECG abnormalities indicative of high risk are inverted or biphasic T waves, ST depression, QT prolongation or dispersion, and BEV originating from the left outflow tract or papillary muscles. The echocardiogram allows the identification of mitral prolapse and disjunction of the mitral annulus (MAD), while MRI shows fibrosis. ICD implantation should be considered in high–risk patients with documented ventricular arrhythmias.

- Abstract
Background Coronary artery disease (CAD) is the leading cause of mortality among diabetic patients, and the neutrophil-to-lymphocyte ratio (NLR) has recently emerged from among inflammatory parameters as a potential indicator of vascular complications and poorer outcome in patients with diabetes. This study aimed to evaluate: 1) the impact of diabetes on NLR; and 2) the role of NLR on the extent of CAD among diabetic patients undergoing coronary angiography. Methods Consecutive patients undergoing coronary angiography were included. Diabetic status and main chemistry parameters were assessed at the time of admission. Significant CAD was defined as at least one vessel with stenosis > 50%, while severe CAD was left main and/or three-vessel disease, as evaluated by quantitative coronary angiography (QCA). Results Diabetes was observed in 1377 of 3756 patients (36.7%); they were older, and displayed higher-risk cardiovascular profile and more complex CAD. Diabetic status was also associated with a significant increase in NLR ( P = 0.004). Among diabetics, higher NLR tertile values were related to ageing ( P < 0.001), dyslipidaemia ( P < 0.001), renal failure ( P < 0.001), body mass index ( P < 0.001), previous percutaneous coronary revascularization ( P = 0.004) and cerebrovascular events ( P = 0.003), acute presentation ( P < 0.001), treatment at admission with beta-blockers/statins/ASA (all P < 0.001), diuretics ( P = 0.01) or clopidogrel ( P = 0.04), platelet count ( P = 0.03), white blood cell count, creatinine, glycaemia and C-reactive protein ( P < 0.001), and inversely related to haemoglobin, triglyceride levels ( P < 0.001) and smoking ( P = 0.03). NLR was associated with multivessel disease ( P < 0.001), degree of stenosis ( P = 0.01), type C lesions ( P = 0.02), coronary calcifications and intracoronary thrombus ( P < 0.001), but inversely with in-stent restenosis ( P = 0.003) and TIMI flow grade ( P = 0.02). Also, NLR was directly related to CAD prevalence ( P < 0.001; adjusted OR [95% CI]: 1.62 [1.27–2.07], P < 0.001) and CAD severity ( P < 0.001; adjusted OR [95% CI]: 1.19 [1.00–1.43], P = 0.05). Conclusion NLR is increased among diabetic patients and, in such patients, is independently associated with the prevalence and severity of CAD. Further studies are now needed to confirm present results and to evaluate the underlying pathophysiological mechanisms behind our findings. [ABSTRACT FROM AUTHOR]

- Abstract
Background and aim There has been a surge of interest in the cardiovascular effects of vitamin D (25(OH)D), preventing the processes leading to vascular wall degeneration and coronary artery disease (CAD). Gender differences have been suggested for vitamin D status, with a higher rate of deficiency occurring especially in post-menopausal women, increasing the risk of bone fractures and osteoporosis. However, to date, few studies have evaluated the differences in 25(OH)D levels according to gender and their impact on the extent of CAD, which was therefore the aim of the present study. Methods and results In patients undergoing coronary angiography, fasting samples were collected for the assessment of 25(OH)D levels. Significant CAD was defined as at least one vessel stenosis >50%, while severe CAD was defined as left main and/or three-vessel disease. Of the 1811 patients included, 530 (29.3%) were females, who displayed older age ( p < 0.001), higher rate of renal failure ( p < 0.001), hypertension ( p = 0.05), treatment with angiotensin-receptor blockers ( p = 0.03) and diuretics ( p < 0.001), acute presentation ( p < 0.001), higher platelet count ( p < 0.001), glycosylated haemoglobin ( p = 0.02) and cholesterol ( p = 0.001), but an inverse relationship with smoking ( p < 0.001), previous cardiovascular events ( p < 0.001), treatment with statins and acetylsalicylic acid (ASA) ( p < 0.001), body mass index ( p = 0.002), haemoglobin ( p < 0.001), leucocytes ( p = 0.03) and triglycerides ( p < 0.001). Female gender was associated with lower vitamin D levels (14.5 ± 10.9 vs. 15.9 ± 9.5, p = 0.007) and independently associated with severe vitamin D deficiency (41.9% vs. 30.4%, p < 0.001; adjusted odds ratio (OR) (95% confidence interval (CI)) = 1.42 (1.08–1.87), p = 0.01). Lower tertiles of vitamin D were associated with an increased prevalence and severity of CAD in females (adjusted OR (95% CI = 1.26 (1.10–1.44), p = 0.001 for CAD; adjusted OR (95% CI) = 1.6 (1.39–1.87), p < 0.001 for severe CAD). In males, vitamin D status was independently related to the prevalence (adjusted OR (95% CI) = 1.28 (1.02–1.61), p = 0.03) of CAD, but not the extent of CAD (adjusted OR (95% CI) = 1.02 (0.86–1.2), p = 0.84). Conclusion Gender significantly affects vitamin D status. The lower 25(OH)D levels observed in females, as compared to males, play a more relevant role in conditioning the severity of CAD.

- Abstract
Background and aim Contrast Induced Nephropathy (CIN) is a common complication of procedures that require the use of contrast media, and seems to be mediated by oxidative stress and reactive oxygen species generation. Hyperuricemia is characterized by inhibited nitric oxide system and enhanced synthesis of reactive oxygen species. However, few studies have so far investigated the association between hyperuricemia and CIN that is therefore the aim of the current study among patients undergoing coronary angiography or percutaneous intervention. Methods and results We analyzed a total of 1950 patients with Creatinine clearance <90 ml/min) undergoing elective or urgent coronary angiography and/or angioplasty. Patients were divided according to tertiles of baseline uric acid (Group 1, ≤5.5 mg/dL n = 653; Group 2, 5.6–7.0 mg/dL, n = 654; Group 3, ≥7.0 mg/dL, n = 643). CIN was defined as an absolute ≥0.5 mg/dl or a relative ≥25% increase in the serum creatinine level at 24 or 48 h after the procedure. Patients with higher uric acid levels were older, previous smokers, with higher prevalence of hypertension and diabetes, but with lower family history of CAD. They had more often history of a previous CABG and baseline renal dysfunction. Patients of the third Tertile had also higher levels of white blood cells, higher triglycerides and lower HDL-cholesterol and higher percentage of dilated cardiomyopathy/valvular disease as indication for angiography and consequently a lower prevalence of PCI. Patients with higher SUA were more often on therapy with ACE inhibitors and diuretics, but less often with statins, nitrate, ASA and Clopidogrel at admission. The occurrence of CIN was observed in 251 patients (12.9%), and was significantly associated with uric acid levels (12.3% in Group 1, 10.4% in Group 2 and 16.0% in Group 3; p = 0.04). Similar results were observed when the analysis was performed according to each tertiles values in both male and female gender. The association between elevated uric acid (≥7 mg/dl) and CIN was confirmed by multivariate analysis after correction for baseline confounding (Adjusted OR [95%CI] = 1.42 [1.04–1.93], p = 0.026). Similar results were observed across major subgroups of high-risk patients, such as patients with diabetes, female gender, renal failure, hypertension, and elderly. Conclusions This is the first large study showing that among patients undergoing coronary angiography or percutaneous interventions elevated uric acid level is independently associated with an increased risk of CIN.

- Abstract
Background and aim High density lipoproteins (HDL) have been addressed as a potential strategy for cardiovascular prevention, with great controversies on pharmacological approaches for HDL-elevation. Our aim was to compare HDL-rising treatment with niacin or CETP-inhibitors with optimal medical therapy in cardiovascular outcome. Methods and results Randomized trials were searched. Primary endpoint was cardiovascular death, secondary were: non fatal myocardial infarction; coronary revascularization; cerebrovascular accidents and safety endpoints. As many as 18 randomized trials, for a total of 69,515 patients, were included. HDL-modifiers did not reduce cardiovascular mortality (2.3%vs3.4%; OR [95%CI] = 0.96 [0.87–1.05], p = 0.37, phet = 0.58), with no benefit from niacin/CETP inhibitors according to patients' risk profile (beta [95%CI] = −0.14 [−0.29 to 0.02], p = 0.09) or the amount of HDL increase (beta [95%CI] = 0.014 [−0.008 to 0.04], p = 0.21). Niacin but not CETP-I reduced myocardial infarction and coronary revascularization, but higher rate of SAE occurred with HDL-modifiers (OR [95%CI] = 1.24 [1.18–1.31], p < 0.00001, phet = 0.02), in particular new onset of diabetes with niacin and worsening of hypertension with CETP-inhibitors. Conclusions Niacin and CETP inhibitors do not influence cardiovascular mortality. Significant benefits in MI and coronary revascularization were observed with niacin, despite the higher occurrence of diabetes. [ABSTRACT FROM AUTHOR]

- Abstract
The commissioning of the EXCYT facility has been recently completed by delivering a post-accelerated radioactive beam to the users. Extensive tests of the whole installation have been accomplished over the last year. At the beginning the source and the mass separator were tested by producing a stable 7Li beam, then the charge exchange cell was tested with the same stable beam, and finally a 8Li beam was produced and transported through the mass separator to the Tandem for the post-acceleration. Acceleration tests at the Tandem have started and will be completed in the next few months. In the last year the upgrading programme of the Superconducting Cyclotron has also gone ahead: significant improvements have been introduced to the electrostatic deflector, in order to increase the extracted current of 13C, 45 AMeV beam, since it was chosen as a primary beam for the 8Li production. The project status is given here, along with a detailed description of the commissioning tests performed and the results obtained.

- Abstract
Advances in growth technology of oxide materials allow single atomic layer control of heterostructures. In particular delta doping, a key materials’ engineering tool in today’s semiconductor technology, is now also available for oxides. Here we show that a fully electric-field-tunable spin-polarized and superconducting quasi-2D electron system (q2DES) can be artificially created by inserting a few unit cells of delta doping EuTiO3at the interface between LaAlO3and SrTiO3oxides. Spin polarization emerges below the ferromagnetic transition temperature of the EuTiO3layer (TFM= 6–8 K) and is due to the exchange interaction between the magnetic moments of Eu-4f and of Ti-3d electrons. Moreover, in a large region of the phase diagram, superconductivity sets in from a ferromagnetic normal state. The occurrence of magnetic interactions, superconductivity and spin–orbit coupling in the same q2DES makes the LaAlO3/EuTiO3/SrTiO3system an intriguing platform for the emergence of novel quantum phases in low-dimensional materials.

Verdoia, M., Schaffer, A., Cassetti, E., Barbieri, L., Di Giovine, G., Marino, P., and De Luca, G.
- Abstract
Abstract: Background and aim: Pro-thrombotic status and platelet hyperreactivity still represent an important challenge for periprocedural myocardial infarction (PMI) after coronary stenting. Hyperhomocysteinemia has been suggested to increase the risk of cardiovascular events. The genetic variant of methylenetetrahydrofolate reductase (MTHFR) 677 C > T has been associated to reduced function of the enzyme, thus inducing hyperhomocysteinemia. In our study we investigated whether MTHFR 677 C > T polymorphism is associated with increased risk of periprocedural MI in patients undergoing coronary stenting. Methods and results: We included 778 patients undergoing PCI. Homocysteinemia and genetic status were assessed at admission for all patients. Myonecrosis biomarkers were dosed at intervals from 6 to 48 h, PMI was defined as CKMB increase by 3 times the ULN or 50% of pre-PCI value, periprocedural myonecrosis for troponin I increase by 3 times the ULN or by 50% of the baseline. As many as 521 patients carried the MTHFR-T allele. No difference was found for main demographical and clinical features nor for biochemistry parameters, but for higher rate of statins treatment (p = 0.03) in T-carriers. Polymorphic patients displayed significantly higher levels of homocysteine (p = 0.005), with additive effect of the mutated T-alleles. Angiographic and procedural features were similar according to genetic status. MTHFR677T was not associated with periprocedural myocardial infarction (adjusted OR = 0.97[0.67–1.4], p = 0.87) or myonecrosis (adjusted OR = 1.03[0.83–1.36], p = 0.82). Same results were found at subgroup analysis in higher-risk subsets of patients. Conclusion: Our study showed that among patients undergoing PCI, MTHFR 677 C > T polymorphism is associated to higher homocysteine levels, but does not influence the risk of periprocedural myocardial infarction.

De Luca, G., Schaffer, A., Verdoia, M., and Suryapranata, H.
- Abstract
Abstract: Background and aim: Clinical trials have reported lower mortality and repeated revascularization rate in diabetic patients treated with coronary artery bypass grafting (CABG) as compared to percutaneous revascularization. However, these studies were conducted in the era of bare-metal stents. Therefore, we performed a meta-analysis to compare CABG to PCI with drug-eluting stents (DES) in diabetic patients with multivessel and/or left main disease. Methods and results: The literature was scanned by formal search of electronic databases (Medline, EMBASE, and Cochrane databases), and major international scientific session abstracts from 2000 to 2013. Primary endpoint was mortality. A total of 14 (4 randomized and 10 non-randomized) trials were finally included, with a total of 7072 patients. Up to 5 years follow-up, CABG was associated with a reduction in mortality (7.3% vs 10.4%, OR[95%CI] = 0.65[0.55–0.77], p < 0.0001; phet = 0.00001), with similar results in both RCTs (OR[95%CI] = 0.64[0.50–0.82], p = 0.0005) and NRCTs (OR[95%CI] = 0.75[0.6–0.94)], p = 0.01) (p int = 0.93). A significant relationship was observed between risk profile and benefits in mortality with CABG (p < 0.001). CABG reduced target vessel revascularization (TVR; 5.2% vs 15.7%, OR[95%CI] = 0.30[0.25–0.36], p < 0.00001, p het = 0.02), with a relationship between risk profile and the benefits from CABG as compared to DES (p < 0.0001). CABG was associated with a lower rate of MACCE (14.9% vs 22.9%, OR[95%CI] = 0.59[0.51–0.67], p < 0.00001, p het<0.00001) but higher risk of CVA (3.6% vs 1.4%, OR[95%CI] = 2.34[1.63–3.35], p < 0.00001, p het = 0.71). Conclusions: The present meta-analysis demonstrates that among diabetic patients with multivessel disease and/or left main disease, CABG provides benefits in mortality and TVR, especially in high-risk patients but it is counterbalanced by a higher risk of stroke. Future trials are certainly needed in the era of new DES and improved antiplatelet therapies. [Copyright &y& Elsevier]

- Abstract
Abstract: Background: Hyperuricemia may be involved in the atherosclerotic process due to endothelial dysfunction and facilitation of smooth muscle cell proliferation. However, debates still exist on the independent role of hyperuricemia, due to its association with several cardiovascular risk factors, such as hypertension, hyperlipidemia, obesity and insulin resistance. Thus, the aim of the current study was to investigate in a consecutive cohort of patients undergoing coronary angiography whether hyperuricemia is associated with the extent of coronary artery disease. Methods and Results: Our population is represented by a total of 1901 consecutive patients undergoing coronary angiography between May 2007 and January 2010 at the Azienda Ospedaliera “Maggiore della Carità”, Novara, Italy. We additionally evaluated platelet aggregation by PFA-100 (Collagen/Epinefrine) and Multiplate. Quantitative coronary angiography and analysis of IMT were performed by experienced cardiologists who had no knowledge of the patients’ clinical information. Higher uric acid was associated with advanced age, larger prevalence of male gender, diabetes, renal insufficiency, hypertension, previous CABG and MI, but with a lower prevalence of family history of CAD. Patients with high uric acid were more often on calcium antagonists, ace-inhibitors, angiotensin receptor antagonists, and, as expected, on diuretics. A significant relationship was observed between uric acid and the prevalence (OR [95% CI] = 1.18 [1.04–1.32], p = 0.01) and severity of CAD (OR [95% CI] = 1.17 [1.03–1.33], p = 0.014). However, the relationship disappeared after correction for baseline confounding factors for both prevalence (OR [95% CI] = 1.06 [0.93–1.21], p = 0.35) and extent of CAD (OR [95% CI] = 1.0 [0.87–1.15], p = 0.96). No relationship was observed between acid uric and IMT (p = 0.73) analyzed in 359 consecutive patients. Finally, there was no relationship between uric acid and platelet aggregation in patients with or without aspirin therapy, as measured by PFA-100 and Multiplate. Conclusions: Our study showed that uric acid is not associated with platelet aggregation, the extent of coronary artery disease and IMT. Thus, waiting for the results of additional large studies, uric acid may not be considered as a risk factor for coronary artery disease, and its reduction by specific therapies may not be recommended to prevent coronary artery disease and atherosclerosis.

MALVASI, A., TINELLI, A., BUIA, A., and DE LUCA, G. F.
- Abstract
The isotretinoin, a 13-cisretinoic acid, has revolutionized the management of severe treatment-resistant acne and it has been widely used for a range of dermatological conditions, in 90% of the time in young women between 13 and 45 years of age. This agent has severe teratogenic effects, as serious craniofacial, cardiovascular, thymic and central nervous system malformations. The baseline population risk of malformations is 3-5%, but it increases to almost 30% in women exposed to isotretinoin during the first trimester of pregnancy. Generally, patients in treatment with isotretinoin avoid eventual pregnancy during assumption and, after its stopping, fertility and foetal development are normal once circulating isotretinoin levels return to normal. There are no known deleterious effects on male fertility and on long term teratogenic effect of isotretinoin. In this report, we suppose the possibility to develop a foetal malformations after a long term wash out from isotretinoin therapy. A 32 year-old healthy nullipara pregnant woman, with an uneventful past gynaecological history, was admitted in Hospital, with a severe depressive syndrome in a 18 weeks malformed pregnancy for thoraco-omphalopagus conjoined twins. She only assumed isotretinoin, at dose of 1 mg/kg a day, for a severe and scarring acne for 7 months. After 3 months of pharmacological wash out, patient become pregnant and manifested this severe malformation. Woman interrupted gestation, by labour induction. [ABSTRACT FROM AUTHOR]

- Abstract
BackgroundPrevious reports have suggested an impact of patient's risk profile and percutaneous coronary intervention (PCI) -- related time delay on the benefits of primary angioplasty as compared with fibrinolysis. However, several factors, such as inappropriate interpretation and definition of delays, missing currently available trials, and arguable risk-benefit analysis, limit the value of these reports. Thus, the aim of the current review is to assess whether the prognostic impact of PCI-related time delay may vary according to patient's risk profile, presentation delay, and type of lytic therapy.MethodsWe obtained results from all randomized trials comparing fibrinolysis and primary angioplasty in ST-segment elevation myocardial infarction. The literature was scanned by formal searches of electronic databases (MEDLINE and CENTRAL) for papers published from January 1990 to April 2007. The following key words were used: randomized trial, myocardial infarction, reperfusion, primary angioplasty, rescue angioplasty, fibrinolysis, thrombolysis, duteplase, reteplase, tenecteplase, and alteplase. Major clinical end point assessed was mortality at 30-day follow-up. The relationship between mortality benefits from primary angioplasty, patient's risk profile, and PCI-related time delay was evaluated by using a weighted least-square regression in which results from each trial were weighted by the square root of the number of patients of each trial.ResultsA total of 27 trials were finally included, with 4399 patients randomized to primary angioplasty and 4474 patients randomized to fibrinolysis. The relationship between the benefits from primary angioplasty and PCI-related time changed according to risk profile. The higher the risk profile, the larger the reduction in mortality benefits from primary angioplasty as compared with fibrinolysis per each 10 minutes of PCI-related time delay (0.75%, 0.45%, and 0%, in high-, medium-, and low-risk patients, respectively). Furthermore, the impact was observed only in trials enrolling patients within the first 6 hours from symptom onset.ConclusionsWhen primary angioplasty is selected as reperfusion strategy, all efforts should be attempted to shorten time-to-treatment, particularly in medium- or high-risk patients and in early presenters, because in these patients, a larger loss of mortality benefits as compared with fibrinolysis is observed per each 10 minutes of PCI-related time delay.© 2009 Elsevier Inc.

C-reactive protein ,INFLAMMATION ,AMNIOTIC liquid ,PREGNANCY ,PLACENTA - Abstract
Objective: C-reactive protein (CRP) is a marker of systemic inflammation. Recently, it has been shown that CRP is present in amniotic fluid and fetal urine, and that elevated levels are associated with adverse pregnancy outcome. However, the precise source of amniotic fluid CRP, its regulation, and function during pregnancy is still a matter of debate. The present in vivo and in vitro studies were designed to investigate the production of CRP in human placental tissues. Material and methods: Ten paired blood samples from peripheral maternal vein (MV), umbilical cord artery (UA) and umbilical vein (UV) were collected from women with elective caesarean sections at term. The placental protein accumulation capacity of hCG, hPL, leptin and CRP was compared with the dual in vitro perfusion method of an isolated cotyledon of human term placentae and quantified by ELISA. Values for accumulation (release) were calculated as total accumulation of maternal and fetal circuits normalized for tissue weight and duration of perfusion. For gene expression, RNA was extracted from placental tissue and reverse transcribed. RT-PCR and real-time PCR were performed using specific primers. Results: The median (range) CRP level was significantly different between UA and UV [50.1ng/ml (12.1–684.6) vs. 61ng/ml (16.9–708.1)]. The median (range) difference between UV and UA was 9.3ng/ml (2.2–31.6). A significant correlation was found between MV CRP and both UA and UV CRP levels. Median (range) MV CRP levels [2649ng/ml (260.1–8299)] were 61.2 (6.5–96.8) fold higher than in the fetus. In vitro, the total accumulation rates (mean±SD) were 31±13 (mU/g/min, hCG), 1.16±0.19 (μg/g/min, hPL), 4.71±1.91 (ng/g/min, CRP), and 259±118 (pg/g/min, leptin). mRNA for hCG, hPL and leptin was detectable using conventional RT-PCR, while CRP mRNA could only be demonstrated by applying real-time RT-PCR. In the perfused tissue the transcript levels for the four proteins were comparable to those detected in the native control tissue. Conclusions: Our results demonstrate that the human placenta produces and releases CRP mainly into the maternal circulation similarly to other analyzed placental proteins under in vitro conditions. Further studies are needed to explore the exact role of placental CRP during pregnancy. [Copyright &y& Elsevier]

- Abstract
We evaluated efficacy of natalizumab in relapsing-remitting multiple sclerosis patients in a clinical practice setting. We report data on the first consecutive 343 patients receiving natalizumab in 12 multiple sclerosis (MS) Italian centers enrolled between April 2007 and November 2010. The main efficacy endpoints were the proportion of patients free from relapses, disease progression, combined clinical activity, defined as presence of relapse or disease progression, from MRI activity, and from any disease activity defined as the absence of any single or combined activity. At the end of follow-up, the cumulative proportion of patients free from relapses was 68%; the proportion of patients free from Expanded Disability Status Scale (EDSS) progression was 93%; the proportion of patients free from combined clinical activity was 65%; the proportion of patients free from MRI activity was 77%; and the proportion of patients free from any disease activity was 53%. Natalizumab was effective in reducing clinical and neuroradiological disease activity. Its effectiveness in clinical practice is higher than that reported in pivotal trials and was maintained over time.

- Abstract
The Campania Region has one of the highest renewable energy potentials in Italy. Despite this high potential, the lack of an integrated energy strategy has allowed for deregulated exploitation of the resources of the territory, e.g. surplus of wind energy occurs in Campania due to the large wind farms, geothermal energy is mainly used for thermal baths but its enthalpy could meet domestic heating demand, etc. A lack of an “integrated planning”, does not to make the best use of resources and to contribute to greenhouse gas (GHG) emission reduction.

- Abstract
Background:Even although time to treatment has been shown to be a determinant of mortality in primary angioplasty, the potential benefits are still unclear from early pharmacological reperfusion by glycoprotein (Gp) IIb‐IIIa inhibitors. Therefore, the aim of this meta‐analysis was to combine individual data from all randomized trials conducted on upstream as compared with late peri‐procedural abciximab administration in primary angioplasty. Methods:The literature was scanned using formal searches of electronic databases (MEDLINE and EMBASE) from January 1990 to December 2010. All randomized trials on upstream abciximab administration in primary angioplasty were examined. No language restrictions were enforced. Results:We included a total of seven randomized trials enrolling 722 patients, who were randomized to early (n = 357, 49.4%) or late (n = 365, 50.6%) peri‐procedural abciximab administration. No difference in baseline characteristics was observed between the two groups. Follow‐up data were collected at a median (25th–75th percentiles) of 1095 days (720–1967). Early abciximab was associated with a significant reduction in mortality (primary endpoint) [20% vs. 24.6%; hazard ratio (HR) 95% confidence interval (CI) = 0.65 (0.42–0.98) P = 0.02, Phet = 0.6]. Furthermore, early abciximab administration was associated with a significant improvement in pre‐procedural thrombolysis in myocardial infarction (TIMI) 3 flow (21.6% vs. 10.1%, P < 0.0001), post‐procedural TIMI 3 flow (90% vs. 84.8%, P = 0.04), an improvement in myocardial perfusion as evaluated by post‐procedural myocardial blush grade (MBG) 3 (52.0% vs. 43.2%, P = 0.03) and ST‐segment resolution (58.4% vs. 43.5%, P < 0.0001) and significantly less distal embolization (10.1% vs. 16.2%, P = 0.02). No difference was observed in terms of major bleeding complications between early and late abciximab administration (3.3% vs. 2.3%, P = 0.4). Conclusions:This meta‐analysis shows that early upstream administration of abciximab in patients undergoing primary angioplasty for ST‐segment elevation myocardial infarction (STEMI) is associated with significant benefits in terms of pre‐procedural epicardial re‐canalization and ST‐segment resolution, which translates in to significant mortality benefits at long‐term follow‐up.

- Abstract
Background:The aim of the current study was to perform two separate meta‐analyses of available studies comparing low‐molecular‐weight heparins (LMWHs) vs. unfractionated heparin (UFH) in ST‐elevation myocardial infarction (STEMI) patients treated (i) with primary percutaneous coronary intervention (pPCI) or (ii) with PCI after thrombolysis. Methods:All‐cause mortality was the pre‐specified primary endpoint and major bleeding complications were recorded as the secondary endpoints. Relative risk (RR) with a 95% confidence interval (CI) and absolute risk reduction (ARR) were chosen as the effect measure. Results:Ten studies comprising 16 286 patients were included. The median follow‐up was 2 months for the primary endpoint. Among LMWHs, enoxaparin was the compound most frequently used. In the pPCI group, LMWHs were associated with a reduction in mortality [RR (95% CI) = 0.51 (0.41–0.64), P < 0.001, ARR = 3%] and major bleeding [RR (95% CI) = 0.68 (0.49–0.94), P = 0.02, ARR = 2.0%] as compared with UFH. Conversely, no clear evidence of benefits with LWMHs was observed in the PCI group after thrombolysis. Meta‐regression showed that patients with a higher baseline risk had greater benefits from LMWHs (r = 0.72, P = 0.02). Conclusions:LMWHs were associated with greater efficacy and safety than UFH in STEMI patients treated with pPCI, with a significant relationship between risk profile and clinical benefits. Based on this meta‐analysis, LMWHs may be considered as a preferred anticoagulant among STEMI patients undergoing pPCI.

- Abstract
Multiple sclerosis (MS) is thought to be an autoimmune T-cell-mediated disease directed at myelin antigens of the central nervous system. Besides myelin proteins, lipid components of CNS are supposed to play a role as antigens for T cells in MS. CD1 is a family of MHC-like glycoproteins specialized in capturing and presenting a variety of microbial and self lipids and glycolipids to antigen-specific T cells. CD1-restricted T cells specific for gangliosides and sulfatide have been isolated from subjects with MS and in mice with experimental allergic encephalopathy. We genotyped exon 2 of CD1A and CD1E in 205 MS patients and 223 unrelated healthy controls and determined their association with the presence of anti-ganglioside and anti-sulfatide antibodies. CD1E 01-01 is associated with a reduced risk of MS (OR 0.54, p=0.001); CD1A 02-02 (OR 1.99, p=0.012) or CD1E 02-02 (OR 2.45, p=0.000) with an increased risk. The combination of the genotypes CD1A 02-02 and CD1E 02-02 is present in 90.7% of patients but in only 9.4% controls (OR 94.16, p= 0.000). CD1A and CD1E polymorphisms contribute to the polygenic susceptibility to MS. The functional effects of CD1 polymorphisms are unknown, however changes in CD1 alleles may affect numerous immunological functions.

50. Nucleation‐Governed Reversible Self‐Assembly of an Organic Semiconductor at Surfaces: Long‐Range Mass Transport Forming Giant Functional Fibers

- Abstract
The use of solvent‐vapor annealing (SVA) to form millimeter‐long crystalline fibers, having a sub‐micrometer cross section, on various solid substrates is described. Thin films of a perylene‐bis(dicarboximide) (PDI) derivative, with branched alkyl chains, prepared from solution exhibit hundreds of nanometer‐sized PDI needles. Upon exposure to the vapors of a chosen solvent, tetrahydrofuran (THF), the needles re‐organize into long fibers that have a remarkably high aspect ratio, exceeding 103. Time‐ and space‐resolved mapping with optical microscopy allows the self‐assembly mechanism to be unravelled; the mechanism is found to be a nucleation‐governed growth, which complies with an Avrami‐type of mechanism. SVA is found to lead to self‐assembly featuring i) long‐range order (up to the millimeter scale), ii) reversible characteristics, as demonstrated through a series of assembly and disassembly steps, obtained by cycling between THF and CHCl3as solvents, iii) remarkably high mass transport because the PDI molecular motion is found to occur at least over hundreds of micrometers. Such a detailed understanding of the growth process is fundamental to control the formation of self‐assembled architectures with pre‐programmed structures and physical properties. The versatility of the SVA approach is proved by its successful application using different substrates and solvents. Kelvin probe force microscopy reveals that the highly regular and thermodynamically stable fibers of PDI obtained by SVA exhibit a greater electron‐accepting character than the smaller needles of the drop‐cast films. The giant fibers can be grown in situ in the gap between microscopic electrodes supported on SiOx, paving the way towards the application of SVA in micro‐ and nanoelectronics.
