Abstract
The current study aimed to investigate alterations of event-related potentials (ERPs) microstate during reward anticipation in subjects with schizophrenia (SCZ), and their association with hedonic experience and negative symptoms. EEG data were recorded in thirty SCZ and twenty-three healthy controls (HC) during the monetary incentive delay task in which reward, loss and neutral cues were presented. Microstate analysis and standardized low-resolution electromagnetic tomography (sLORETA) were applied to EEG data. Furthermore, analyses correlating a topographic index (the ERPs score), calculated to quantify brain activation in relationship to the microstate maps, and scales assessing hedonic experience and negative symptoms were performed. Alterations in the first (125.0-187.5 ms) and second (261.7-414.1 ms) anticipatory cue-related microstate classes were observed. In SCZ, reward cues were associated to shorter duration and earlier offset of the first microstate class as compared to the neutral condition. In the second microstate class, the area under the curve was smaller for both reward and loss anticipation cues in SCZ as compared to HC. Furthermore, significant correlations between ERPs scores and the anticipation of pleasure scores were detected, while no significant association was found with negative symptoms. sLORETA analysis showed that hypo-activation of the cingulate cortex, insula, orbitofrontal and parietal cortex was detected in SCZ as compared to HC. Abnormalities in ERPs could be traced already during the early stages of reward processing and were associated with the anticipation of pleasure, suggesting that these dysfunctions might impair effective evaluation of incoming pleasant experiences. Negative symptoms and anhedonia are partially independent results.

Abstract
BACKGROUND Over the past decades, the improvements in the diagnostic power and availability of non-invasive cardiac imaging techniques have led to a decline of right heart catheterization (RHC) performance. However, RHC remains the gold standard for diagnosing pulmonary hypertension and an essential tool for the evaluation of patient candidacy to heart transplantation. METHODS This survey was carried out jointly by the Young Committee of GISE, with the support of the SICI-GISE Society, and the ICOT group, with the aim of evaluating how the interventional cardiology community perform RHC. A web-based questionnaire based on 20 questions was distributed to SICI-GISE members. RESULTS The survey was distributed to 1550 physicians with 174 (11%) responses. Most centers perform few procedures per year (<10 RHC/year) and a dedicated cardiologist is usually lacking. Patients were frequently admitted as ordinary hospitalization regimen and the most frequent indication for RHC was the hemodynamic assessment of pulmonary hypertension, followed by diagnostics of valvular diseases and advanced heart failure/heart transplantation. Indeed, the majority of participants (86%) are involved in transcatheter procedures for structural heart disease. The average time taken to perform the RHC was approximately 30-60 min. The femoral access (60%) was the most frequently used, usually by an echo-guided approach. Two-thirds of participants discontinued oral anticoagulant therapy before RHC. Only 27% of centers assess wedge position from an integrated analysis. Furthermore, the edge pressure is detected in the end-diastolic cardiac phase in half cases and in the end-expiratory phase in only 31%. The most commonly used method for cardiac output calculation was the indirect Fick method (58%). CONCLUSIONS Guidance on the best practice for performing RHC is currently lacking. A more precise standardization of this demanding procedure is warranted.

Abstract
OBJECTIVE To evaluate whether cervical pessary effectively reduces the preterm birth < 37 weeks rate in patients who have not delivered after an episode of arrested preterm labor. PATIENTS AND METHODS Retrospective cohort study was conducted on singleton pregnant patients admitted to our institution between January 2016 and June 2021 for threatened preterm labor and who had a cervical length < 25 mm. Women in whom a cervical pessary was placed were considered as exposed, while women in whom expectant management was preferred were considered as unexposed. The primary outcome was the rate of preterm birth before 37 weeks. A targeted maximum likelihood estimation was used to estimate the average treatment effect of cervical pessary by adjusting for a-priori-defined confounders. RESULTS A cervical pessary was placed in 152 (36.6%) patients (exposed), while the remaining 263 (63.4%) were managed expectantly (unexposed). The adjusted average treatment effect was -14% (-18 to -11%), -17% (-20 to -13%), and -16% (-20 to -12%) for preterm birth < 37 weeks, < 34 weeks, and < 32 weeks, respectively. The average treatment effect for adverse neonatal outcomes was -7% (-8 to -5%). No difference in gestational weeks at delivery between exposed and unexposed emerged when gestational age at first admission was > 30.1 gestational weeks. CONCLUSIONS The positioning of a cervical pessary placement may be evaluated to reduce the risk of a subsequent preterm birth after an episode of arrested preterm labor in pregnant patients with onset of symptoms before 30 gestational weeks.

Abstract
AIMS To identify the best strategy to achieve complete revascularization (CR) in patients with ST-elevation myocardial infarction (STEMI) and multi-vessel disease (MVD). METHODS AND RESULTS We systematically reviewed the literature for randomized controlled trials (RCTs) comparing IRA-only PCI and CR guided by angiography or fractional flow reserve (FFR) in MVD-STEMI. Both frequentist (classical) and Bayesian network meta-analysis were performed, including a comparative hierarchy estimation of the probability to reduce the primary composite endpoint of all-cause death and new myocardial infarction (MI). We identified 11 RCTs, including 8193 STEMI patients. Compared with IRA-only strategy, CR significantly reduced the primary endpoint (OR: 0.73; 95%CI0.55-0.97). We observed non-significant difference between angiography and FFR guidance in reducing the primary endpoint (OR: 0.73, 95% CI 0.35-1.57). The Bayesian probability analysis ranked angio-guided CR as the best intervention yielding lowest risk of all-cause death or new MI (SUCRA92%). CONCLUSIONS In patients with MVD-STEMI, CR is associated with a reduction in all-cause mortality and new MI compared with IRA-only PCI. Angio-guided CR is associated with the lowest risk of all-cause death or new MI, therefore the role of FFR-guidance in this setting is questionable. CONDENSED ABSTRACT Both frequentist and Bayesian network meta-analysis were performed to compare infarct-related artery (IRA)-only percutaneous coronary intervention (PCI) and complete revascularization (CR) guided by angiography or fractional flow reserve (FFR) in multivessel disease (MVD) and acute ST-elevation myocardial infarction (STEMI). Eleven randomized controlled trials were identified, including 8193 STEMI patients. Compared with IRA-only strategy, CR significantly reduced the incidence of the composite endpoint of all-cause death and new myocardial infarction without significant difference in angio-guided and FFR-guided CR. The Bayesian probability analysis ranked angio-guided CR as the best intervention yielding lowest risk of the composite endpoint and, therefore the role of FFR-guidance in this setting is questionable.

Abstract
Abstract
Background and aim
Right heart catheterization (RHC) is the gold standard for the diagnosing and classifying pulmonary hypertension (PH). Cardiac output (CO) and the derived cardiac index (CI) are cornerstones of the hemodynamic evalution allowing pulmonary vascular resistance (PVR) calculation and risk stratification. According to the current European Guidelines, CO should be assessed by the direct Fick method or thermodilution (TD). The indirect Fick (IF) method based on theorically estimated values for VO2, is deemed acceptable bul lacks reliability. Of note, data from the literature on a direct comparison among these three methods used for CO measurement are poor.
The objective of our study is to compare CO evaluation by the DF method (DFCO) with CO assessed by IF (IFCO) and TD (TDCO). Secondly, we aimed at assessing the impact of CO estimation by different methods on PVR measurement and therefore on PH hemodynamic classification. This might translate into relevant diagnostic, prognostic and therapeutic implications.
Methods
27 patients underwent RHC. Breath-by breath VO2 was measured through a Rudolph mask connected with a two-way respiratory valve to a metabolic cart and averaged over the course of 12 to 15 minutes. DFCO was calculated using the following formula: VO2 (ml/min)/(arteriovenous oxygen content difference×10). For IFCO, the same formula was used with VO2 computed by the Dehmer and the LaFarge-Miettinen formulas. TDCO was obtained through the injection of 10 ml of cold saline solution (0-4°C), in the right atrium and by measuring the temperature variation in the pulmonary artery.
Results
RHC revealed PH in 23 patients (85%) Average VO2 by Dehmer formula differed significantly from direct measurement (228.9 ± 27.9 ml/min and 204.4 ± 43.6 ml/min respectively; P = 0.017). By using LaFarge formula, mean estimated VO2 differed from direct measurement without reaching statistical significance (185.3 ± 31.9 ml/min and 204.4 ± 43.6 ml/min respectively, P= 0.072). Average CO values did not differ significantly from each other (DFCO 4.2 ± 1.5 L/min; IFCO 4.7 ± 1.3 L/min; TDCO 4.6 ± 1.2 L/min; P=NS for all pairwise comparisons) and showed significant Pearson's correlation. Out of 27 cases, TDCO differed for more (± 0.5 L/min) than 10% as compared to DFCO in 17 (63%). IFCO differed consistently from DFCO in 12 (44%) and IFCO from TDCO in 17 (63%).
Despite discrepancies among different CO measurement methods, Cohen's kappa coefficient showed good agreement between the three methods in high PVR (≥3 WU) estimation (IF vs DF 0.79; TD vs DF 0.83 and IF vs TD 0.92 respectively).
Conclusions
Our results indicate consistent discrepancies among different approaches for VO2 and CO measurement, however this did not impact over PVR assessment and therefore in PH classification. Probably, this is due to the small sample size and the low number of patients (8 of 27) with values around the pathological cut-off for PVR (3 WU).
Further studies are needed to better investigate the magnitude of CO measurement discrepancies among different methods on PVR calculation and hemodynamic classification.

Abstract
Abstract
Background
RHC is currently the gold standard in the assessment of diagnosis, prognostic evaluation, and decision-making of pulmonary hypertension patients. Internal jugular vein (IJV) access is the preferred option among the available vascular access routes in most of pulmonary hypertension centers; furthermore, ultrasound (US) guidance is strongly recommended for the IJV access (IA) since it reduces the number of access complications. Many patients requiring RHC are on long-term oral anticoagulant therapy. Continuation of direct oral anticoagulant (DOAC) has been shown to be safe in patients undergoing percutaneous coronary intervention (PCI) and cardiac implantable electronic device implantation (CIED). However only few data in the literature are available in the setting of RHC.
Objectives
To compare the feasibility and safety of ultrasound (US)-guided IJV access for RHC procedure in pulmonary hypertension's patients anticoagulated vs non-anticoagulated.
Methods
This is a retrospective observational single–center study, including a cohort of 114 consecutive patients undergoing RHC via IJV assess by US guidance RHC at our tertiary care center between February 2018 and February 2022. The primary outcome was a composite of general (defined as overall success rate, patient discomfort, syncope, mortality) and access site complications (defined as significant hematoma formation greater than 5 cm in diameter, thrombosis, embolism, arterial puncture, pneumothorax, haemotomediastinum and hydro mediastinum, subcutaneous emphysema and nerve injury) after adequate hemostasis, at the access site at 6-hour post procedure.
Results
Of the 114 patients, 50 (44%) were on anticoagulation and 64 (56%) were not. Mean age was 71 ± 13 and 59 ± 16 years, respectively. The main indication for anticoagulation was atrial fibrillation in 40 (80%) patients. 43 (86%) patients were on DOAC, only 7 (14%) on Warfarin. 13 patients were on single antiplatelet therapy and 8 were on double antiplatelet therapy. Mean INR value was 1.25 ± 0.33 in the anticoagulated population and 1.08 ± 0.11 in the non-anticoagulated one. HAS-BLED score was equal or greater than 3 in 29 (25%) patients. Indication for RHC was mainly confirmation of PH class I diagnosis (54% of patients). None of the patients enrolled developed general or access site complications, except for 1 (2%) non-anticoagulated patient who develop a significant hematoma (defined as >5 cm in diameter) at the puncture site. All patients underwent day-hospital regimen, were able to mobilize immediately following the procedure, and were discharged as planned at 6 hours.
Conclusions
To the best of our knowledge this is the first study in the literature supporting the feasibility and safety of US guided IJV approach to RHC in anticoagulated patients when compared to non-anticoagulated patients affected by pulmonary hypertension.

Abstract
OBJECTIVES We aim to define whether the timing of microaxial left ventricular assist device (IMLVAD) implantation might impact on mortality in acute myocardial infarction (AMI) cardiogenic shock (CS) patients who underwent primary percutaneous coronary intervention (PPCI). BACKGROUND Despite the widespread use of PPCI, mortality in patients with AMI and CS remains high. Mechanical circulatory support is a promising bridge to recovery strategy, but evidence on its benefit is still inconclusive and the optimal timing of its utilization remains poorly explored. METHODS We compared clinical outcomes of upstream IMLVAD use before PPCI versus bailout use after PPCI in patients with AMI CS. A systematic review and meta-analysis of studies comparing the two strategies were performed. Effect size was reported as odds ratio (OR) using bailout as reference group and a random effect model was used. Study-level risk estimates were pooled through the generic inverse variance method (random effect model). RESULTS A total of 11 observational studies were identified, including a pooled population of 6759 AMI-CS patients. Compared with a bailout approach, upstream IMLVAD was associated with significant reduction of 30-day (OR = 0.65; 95% confidence interval [CI] = 0.51-0.82; I2 = 43%, adjusted OR = 0.54; 95% CI = 0.37-0.59; I2 = 3%, test for subgroup difference p = 0.30), 6-month (OR = 0.51; 95% CI = 0.27-0.96; I2 = 66%), and 1-year (OR = 0.56; 95% CI = 0.39-0.79; I2 = 0%) all-cause mortality. Incidence of access-related bleeding, acute limb ischemia and transfusion outcomes were similar between the two strategies. CONCLUSION In patients with AMI-CS undergoing PPCI, upstream IMLVAD was associated with reduced early and midterm all-cause mortality when compared with a bailout strategy.

Abstract
Background Primary percutaneous coronary intervention (pPCI) in ST-segment elevation myocardial infarction (STEMI) can be challenging for high thrombus burden and catecholamine-induced vasoconstriction. The Xposition-S stent was designed to prevent stent undersizing and minimize strut malapposition. We evaluated 1-year clinical outcomes of a nitinol, self-apposing®, sirolimus-eluting stent, pre-mounted on a novel balloon delivery system, in de novo lesions of patients presenting with STEMI undergoing pPCI. Methods The iPOSITION is a prospective, multicenter, post-market, observational study. The primary endpoint, target lesion failure (TLF), was defined as the composite of cardiac death, recurrent target vessel myocardial infarction (TV-MI), and clinically driven target lesion revascularization (TLR). Results The study enrolled 247 STEMI patients from 7 Italian centers. Both device and procedural success occurred in 99.2% of patients, without any death, TV-MI, TLR, or stent thrombosis during the hospital stay and at 30-day follow-up. At 1 year, TLF occurred in 2.6%, cardiac death occurred in 1.7%, TV-MI occurred in 0.4%, and TLR in 0.4% of patients. The 1-year stent thrombosis rate was 0.4%. Conclusions The use of an X-position S self-apposing® stent is feasible in STEMI pPCI, with excellent post-procedural results and 1-year outcomes.

Abstract
Right heart catheterization (RHC) is a key diagnostic tool in several clinical conditions. It is recognized to be a technically demanding procedure requiring accurate evaluation of results. If performed by skilled operators, RHC provides reliable and valuable measurements with low complication rates. Although increasing data from the literature have become available over time, a comprehensive review of technical details and pitfalls is rare. This article aims to provide an overview of indications and evidence-based practical issues upon RHC to guide interventional cardiologists on how to perform this procedure.

Abstract
Introduction Despite innovative treatments, the impairment in real-life functioning in subjects with schizophrenia (SCZ) remains an unmet need in the care of these patients. Recently, real-life functioning in SCZ was associated with abnormalities in different electrophysiological indices. It is still not clear whether this relationship is mediated by other variables, and how the combination of different EEG abnormalities influences the complex outcome of schizophrenia. Objectives The purpose of the study was to find EEG patterns which can predict the outcome of schizophrenia and identify recovered patients. Methods Illness-related and functioning-related variables were measured in 61 SCZ at baseline and after four-years follow-up. EEGs were recorded at the baseline in resting-state condition and during two auditory tasks. We performed Sparse Partial Least Square (SPLS) Regression, using EEG features, age and illness duration to predict clinical and functional features at baseline and follow up. Through a Linear Support Vector Machine (Linear SVM) we used electrophysiological and clinical scores derived from SPLS regression, in order to classify recovered patients at follow-up. Results We found one significant latent variable (p<0.01) capturing correlations between independent and dependent variables at follow-up (RHO=0.56). Among individual predictors, age and illness-duration showed the highest scores; however, the score for the combination of the EEG features was higher than all other predictors. Within dependent variables, negative symptoms showed the strongest correlation with predictors. Scores resulting from SPLS Regression classified recovered patients with 90.1% of accuracy. Conclusions A combination of electrophysiological markers, age and illness-duration might predict clinical and functional outcome of schizophrenia after 4 years of follow-up.

Abstract
Introduction Different electrophysiological indices have been investigated to identify diagnostic and prognostic markers of schizophrenia (SCZ). However, these indices have limited use in clinical practice, since both specificity and association with illness outcome remain unclear. In recent years, machine learning techniques, through the combination of multidimensional data, have been used to better characterize SCZ and to predict illness course. Objectives The aim of the present study is to identify multimodal electrophysiological biomarkers that could be used in clinical practice in order to improve precision in diagnosis and prognosis of SCZ. Methods Illness-related and functioning-related variables were measured at baseline in 113 subjects with SCZ and 57 healthy controls (HC), and after four-year follow-up in 61 SCZ. EEGs were recorded at baseline in resting-state condition and during two auditory tasks (MMN-P3a and N100-P3b). Through a Linear Support Vector Machine, using EEG data as predictors, four models were generated in order to classify SCZ and HC. Then, we combined unimodal classifiers’ scores through a stacking procedure. Pearson’s correlations between classifiers score with illness-related and functioning-related variables, at baseline and follow-up, were performed. Results Each EEG model produced significant classification (p < 0.05). Global classifier discriminated SCZ from HC with accuracy of 75.4% (p < 0.01). A significant correlation (r=0.40, p=0.002) between the global classifier scores with negative symptoms at follow-up was found. Within negative symptoms, blunted affect showed the strongest correlation. Conclusions Abnormalities in electrophysiological indices might be considered trait markers of schizophrenia. Our results suggest that multimodal electrophysiological markers might have prognostic value for negative symptoms.

Abstract
Background Selexipag is an oral selective prostacyclin IP receptor agonist approved in patients with low- and intermediate-risk pulmonary hypertension (PH); evidence in patients at high risk is lacking. Case summary A 42-year-old woman with worsening dyspnoea (World Health Organization functional class III–IV) and suspected PH at echocardiographic examination was evaluated in our Pulmonary Hypertension Centre. Right heart catheterization showed pre-capillary PH with reduced cardiac index and increased pulmonary vascular resistance. High-resolution computed tomography excluded parenchymal lung disease and ventilation/perfusion (V/Q) lung scan was negative for mismatched perfusion defects so the conclusive diagnosis was high-risk idiopathic pulmonary arterial hypertension (PAH). The patient refused an initial combination therapy including a parenteral prostacyclin analogue (PCA) in accordance with the ESC/ERS guidelines, so an off-label triple oral combination therapy including a phosphodiesterase-5 inhibitor, an endothelin receptor antagonist, and selexipag was started. At 3- and 6-month follow-up we found a clinical and haemodynamic improvement, so the patient was reclassified as low risk. Her clinical condition is currently stable. Discussion Despite the benefit of parenteral PCAs in high-risk PAH, low adherence to treatment may be explained by adverse side effects related to the intravenous route of administration. Given the potential effect seen in our patient, upfront triple oral combination therapy in PAH high-risk patients should be further evaluated in a controlled clinical trial.

Abstract
Official Method SM 2011.14/ISO 15151:2018/IDF 229:2018 uses microwave digestion of samples and inductively coupled plasma–atomic emission spectrometry for determination of nine elements, including Ca, Cu, Fe, K, Mg, Mn, Na, P, and Zn. The method was evaluated in a collaborative study of 25 products, including 13 fortified nutritional products (powders, ready-to-feed liquids, and liquid concentrates), five product placebos, six dairy products (liquids, powders, butter, and processed cheese), and the National Institute for Standards and Technology (NIST) Standard Reference Material (SRM) 1849a, in compliance with AOAC INTERNATIONAL Standard Method Performance Requirement (SMPR®) 2014.004. This study significantly expanded the applicability of Official Method 2011.14 beyond the original scope of chocolate milk powder, dietetic milk powder, infant cereal, peanut butter, and wheat gluten. The study included 14 collaborators from 11 countries, and results were compared to SMPR 2014.004. Accuracy of the method was demonstrated using NIST SRM 1849a, yielding recoveries across all laboratories of 98–101% for the nine elements. Precision for the 13 fortified nutritional product samples was 2.2–3.9% for repeatability (relative SD of repeatability) and 6.0–12.2% for reproducibility (RSDR). Excluding Mn, which was present at a wide range of concentrations, the reproducibility was 6.0–9.5%, meeting the performance requirements of SMPR 2014.004. Placebo samples (not fortified with Cu, Fe, Mn, or Zn) yielded acceptable repeatability of 1.8–2.9% for Ca, K, Mg, Na, and P (minerals) but 5.4–29.4% for the low levels of Cu, Fe, Mn, and Zn (trace elements). Reproducibility for the placebos showed the same pattern, with acceptable reproducibility (5.4–10.3%) for minerals but not for the low levels of the trace elements (13.2–82.8%). In the six dairy product samples, repeatability ranged from 1.6 to 3.6% for the minerals, Zn, and the low range of Mn but from 9.4 to 24.6% for Cu, Fe, and the high range of Mn, where concentrations were low as for the nutritional placebos. Reproducibility in the dairy samples was 5.3–8.8% for the minerals but 11.4–55.0% for the trace elements. The mean concentrations of Cu, Fe, and Zn in the dairy products were similar with those in the placebo products, while Zn was present at levels more similar with the fortified nutritional products. Thus, the method met the SMPR criteria except where the trace minerals were present at very low levels. Based on these results, the AOAC Stakeholder Panel for Infant Formula and Adult Nutritionals recommended Final Action status of the expanded applicability of the method. The method was adopted as Final Action by the AOAC Official Methods Board.

Abstract
Abstract
Background
Marfan Syndrome (MFS) is a rare multisystemic genetic disease caused by mutations in the Fibrillin 1 (FBN1) gene. Aortic root aneurysm, potentially evolving to dissection and rupture, is the most important clinical complication. Beta blockers (BB) and Angiotensin II receptor blockers (ARB), these latter exerting an anti-TGFbeta1 effect, are current cornerstones of medical therapy in patients diagnosed with MFS and presenting aortic root aneurysm. The study aimed at comparing the effect of single drug (nebivolol and losartan) vs. the combination of both (losartan + nebivolol) in limiting the progression of the growth of the aortic root diameter (ARD) in FBN1 genotyped patients with aortic root aneurysm (z-score>2), who had not undergone prior aortic surgery.
Methods
We designed a controlled, open-label, single-blinded, 1:1:1 randomized, phase III single-centre study [NCT00683124]. Calculated sample size was 291 (power 90%, type I error 5%, 20% attrition, expected dropout 20%). ARD data collection was performed with annual 2D-transthoracic echocardiograms for four years. ARDs were measured with 2D-transthoracic echocardiogram as absolute values, aortic root ratio (ARR), and z-score. The primary endpoint was the modification of ARD z-score at 48 months. The analysis of the primary endpoint aimed at showing differences of ARD z-score comparing:
– The combined treatment arm (group A).
– The group aggregating both single treatment arms (group B).
– The nebivolol arm (group C).
– The losartan arm (group D).
Results
We enrolled 262 patients (126 adults, aged 17–55, and 136 children, aged 1–16); 236/262 (22 dropout; 4 lost at follow-up) completed the planned follow-up: 81 in the group A, 79 in the BB in the group C and 76 in the group D. No patient developed acute aortic dissection. Both drugs administered either individually or in combination were well tolerated without evidence of side effects. At 48 months, the ARD Z-score decreased from baseline to end-follow-up in all treatment arms. The decrease was significantly higher in the combined treatment arm (A) than in the single treatment aggregated arm (group B) with a difference in ARD z-score change of 0.17 (p=0.009) in the combined arm (A). Similarly, the decrease of z-score was inferior in the nebivolol arm and in the losartan arm than in the combined arm (by 0.16, p=0.032, and by 0.18, p=0.019, respectively). After Bonferroni correction for these post-hoc comparisons only the decrease of z-score in the losartan arm remained significantly inferior (p<0.025).
Conclusions
This study shows that the current cornerstones of medical therapy in MFS (ARB and BB) are effective in limiting the progression of the growth of the aortic root diameter: their combination exploits a synergistic effect. The combined administration of BB and ARB in patients with aortic root aneurysm is a sustainable, well tolerated treatment that effectively limits the rate of progression of aortic root dilation.

Abstract
Abstract
Next Generation Sequencing (NGS) technology has taken a central role in the diagnosis of genetically-determined cardiovascular diseases. The differentiation of sequencing errors from real variants is a key-point of the genetic testing. In case of novel variants or variants of uncertain significance that may potentially impact on clinical decisions (e.g. ICD implantation in primary cardiomyopathies or preventive surgery in heritable aneurysmal diseases) it is crucial to exclude false positive (FP) and false negative (FN) sequence errors. To date, Sanger Sequencing is the gold standard tool used to confirm and validate NGS-identified variants. While FPs are excluded by the Sanger confirmation and the damage is for wasted costs and time, the FNs are non-resolvable errors because they are undetected and, obviously, not searched in Sanger confirmation, with the risk of missing genetic diagnoses.
Purpose
This project aimed at reducing NGS errors through the introduction of a bioinformatic solution in the bioinformatic analytic step of the genetic testing process. iEVA is a tool that enhances NGS-derived informative features to use them in a filtering process based on a Machine Learning algorithm (ML). It considers sequencing features (e.g. technical errors, duplicates of PCR) together with nucleotide sequence characteristics.
Methods
To demonstrate the effectiveness of iEVA in eliminating FP and FN errors from the NGS bioinformatic pipeline, we developed two ML-based filtering algorithms. The training dataset consisted of 7968 single nucleotide variants (SNV) and 306 Insertions and Deletions (InDels) validated by Sanger sequencing performed by expert molecular biologists. Variants derived from 800 sequences obtained with the Illumina Trusight Cardio panel containing 174 genes related to cardiovascular diseases. Two Random Forest classifiers were trained with the task of discriminating between sequencing error and real variant. The first one was trained using attributes derived from the most common variant caller (GATK v3.8), and the second one using iEVA results. To evaluate ML models, we used a 3-Fold cross-Validation and validated the results using an independent validation dataset consisting of 3415 SNV and 132 InDels.
Results
Using iEVA attributes, we obtained 1 FP (excluded by Sanger) and 3 FN (confirmed by Sanger) less than using common variant caller attributes. In the independent validation dataset, the iEVA-trained classification model identified 1 Sanger-confirmed variant that was missed by variant caller-trained model.
Conclusions
Variant filtering is crucial to exclude sequencing errors and to recognize true variants. Even a single filtering error may negatively impact on the patient when a genetic diagnosis is missed. To obtain a certain genetic diagnosis, a 0% error probability is needed. The introduction of iEVA in the pipeline is an easy, time- and cost-saving tool to reduce errors and to improve the precision of the genetic data.

Abstract
Abstract
Introduction
SCAD is a rare coronary event that may cause acute coronary syndromes (ACS). SCAD predominantly occurs in apparently healthy, young to middle aged women (up to 95% of cases). The known causes include: heritable connective tissue diseases, fibromuscular dysplasia, arteritis, contraceptives, cocaine abuse and chest trauma. A variable proportion of patients manifests progression to longer segments of the same vessel or recurrence of dissection in other coronary arteries. SCAD can be the first manifestation of a previously unrecognised systemic disease.
Methods
In 2010 we started collecting consecutive SCAD, as first clinical manifestation, in patients addressed to our attention for investigation of genetic or non genetic causes, after successful management of the acute phase and exclusion of systemic inflammatory and autoimmune diseases. All patients underwent genetic visit and counselling, collection of clinical reports and imaging records, clinical cardiologic evaluation with pan-angio CT scan, biochemical testing including coagulation-related tests, and and genetic testing of genes causing connective tissue diseases. Parallel clinical family screening and genetic testing were systematically performed.
Results
The series is constituted of 35 patients (28F and 7M) (age at onset, mean ± SD, 44±7.6 years) with ACS-SCAD (20 STEMI and 15 NSTEMI) and 9 second dissections in a different coronary artery. Two sisters had ACS-SCAD caused by dissection of the same coronary artery.
We identified pathologic mutations (n=19/35, 54%) in COL3A1 (n=3), FBN1 (n=1), FBN1+TGFBR1 (n=1), TGFBR1 (n=2), TGFBR2 (n=1), MYLK (n=1), SMAD3 (n=1), COL5A1 (n=1 homozygous), COL5A2 (n=1), MYH11 (n=1), TGFB2 (n=1), ABCC6 (1 homozygous), ELN (2 homozygous sisters and 1 heterozygous unrelated patient), NOTCH1 (n=1). In 8 (23%) patients we identified VUS classified as C3 because previously unreported and predicted as uncertain on the basis of in silico analyses. In the remaining 8 patients we only identified C2 variants. A second SCAD (14 days to 78 months after the first event) occurred in 9 patients (9/35, 25%) (COL3A1 (n=2), FBN1 (n=1), FBN1+TGFBR1 (n=1), MYLK (n=1), COL5A2 (n=1), NOTCH1 (n=1) COL5A2 (n=1) and 1 with a C2 variant in COL3A1. Two patients with thrombocytosis were carriers of the somatic JAK2 V617F mutation. Extra-coronary arterial dilations/aneurysms occurred in 13 families; in the follow-up 2 patients demonstrate dissection in non-coronary arteries.
Conclusions
Our series, with the potential bias of a referral centre for inherited cardiovascular disease, demonstrated that SCAD is the possible first manifestation of a genetic disorder and that neither disease gene or mutation predicts the risk of a second coronary event. SCAD is a potentially fatal coronary event associated with ACS, warning for familial disease and unpredictable risk of recurrence.

Abstract
Epidemiological studies have suggested that human exposure to extremely low-frequency electromagnetic fields from the electric power and to mobile phone radiofrequency electromagnetic fields induce an increased risk of developing malignant tumours. However, no adequate laboratory data, in particular long-term carcinogenicity bioassays to support the epidemiological evidence, have yet been available. This motivated the Ramazzini Institute to embark on a first project of four large life-span carcinogenic bioassays conducted on over 7000 Sprague Dawley rats exposed from prenatal life until natural death to S-50 Hz MF alone or combined with gamma radiation or formaldehyde or aflatoxin B1. Results now available from these studies, which started concurrently, have shown that exposure to Sinusoidal-50 Hz Magnetic Field (S-50 Hz MF) combined with acute exposure to gamma radiation or to chronic administration of formaldehyde in drinking water induces a significantly increased incidence of malignant tumours in males and females. A second project of two large life-span carcinogenic bioassays was conducted on over 3000 Sprague Dawley rats exposed from prenatal life until natural death to 1.8 GHz GSM of mobile phone radio base station, alone or combined with acute exposure to gamma radiation. Early results from the experiment on 1.8 GHz GSM alone show a statistically significant increase in the incidence of heart malignant schwannoma among males exposed at the highest dose.

Abstract
BACKGROUND Experimental rodent bioassays performed up to now have failed to provide conclusive confirmation of the carcinogenicity of extremely low frequency magnetic fields (ELFMF). OBJECTIVES To evaluate the potential synergistic carcinogenic effects of concurrent exposure to ELFMF and formaldehyde in four groups of male and female Sprague-Dawley rats. METHODS One group was exposed from prenatal life until natural death to S-50 Hz MF and to formaldehyde in drinking water from 6 weeks of age for 104 weeks, two groups were treated only with formaldehyde or only with MF and one group served as untreated control. RESULTS Compared to untreated controls, exposure to MF and formaldehyde causes in males a statistically significant increased incidence of malignant tumors (P ≤ 0.01), thyroid C-cell carcinomas (P ≤ 0.01), and hemolymphoreticular neoplasias (P ≤ 0.05). No statistically significant differences were observed among female groups. CONCLUSIONS Life-span exposure to MF and formaldehyde induces statistically significant carcinogenic effects in male rats.

Abstract
Aminopenicillins are the most used β-lactam antibiotics. Morbilliform or maculopapular rashes are rather frequent during therapy with aminopenicillins. The pathogenesis of these reactions is often due to a cell-mediated allergy. The aim of this work is to characterize patients with cell-mediated allergy to aminopenicillins and to identify alternative β-lactam drugs that can be safely administered to these patients. We studied 27 subjects affected by cell-mediated allergy to aminopenicillins. The diagnosis was made on the basis of positivity of patch tests with aminopenicillins. These patients then underwent an allergological evaluation (skin and patch tests, oral and/or intramuscular challenge tests) with a wide spectrum of β-lactam antibiotics. Our work highlights the following main characteristics of cell-mediated allergy to aminopenicillins: time elapsing between drug administration and onset of symptoms of about 2 days; the maculopapular rash and delayed appearance of urticaria/angioedema were the most typical symptoms (82.8% of cases); a cross-reactivity with aminocephalosporins is usually absent, or it is limited to cephalexin (in our study, in fact, just 3 out of 20 patients challenged with cephalexin showed a positive oral challenge test); all the β-lactams, other than aminopenicillins, are well tolerated. Patch tests represent a specific diagnostic tool with a good predictive value of identifying alternative drugs that can be safely administered to patients with β-lactam allergy. Our patients could tolerate other β-lactam drugs after a complete allergological evaluation. On the basis of our study, cell-mediated allergy to aminopenicillins should be considered a well-defined nosologic entity.

Abstract
Background In 2002 the International Agency for Research on Cancer classified extremely low frequency magnetic fields (ELFMF) as a possible carcinogen on the basis of epidemiological evidence. Experimental bioassays on rats and mice performed up to now on ELFMF alone or in association with known carcinogens have failed to provide conclusive confirmation. Objectives To study the carcinogenic effects of combined exposure to sinusoidal-50 Hz (S-50 Hz) magnetic fields and acute γ radiation in Sprague-Dawley rats. Methods We studied groups of male and female Sprague-Dawley rats exposed from prenatal life until natural death to 20 or 1000 μT S-50 Hz MF and also to 0.1 Gy γ radiation delivered as a single acute exposure at 6 weeks of age. Results The results of the study showed significant carcinogenic effects for the mammary gland in males and females and a significant increased incidence of malignant schwannomas of the heart as well as increased incidence of lymphomas/leukemias in males. Conclusions These results call for a re-evaluation of the safety of non-ionizing radiation.

Abstract
Background Few studies have investigated the toxicity and genotoxicity of extremely low frequency magnetic fields (ELF-MF) during prenatal and neonatal development. These phases of life are characterized by cell proliferation and differentiation, which might make them sensitive to environmental stressors. Although in vitro evidences suggest that ELF-MF may modify the effects of ionizing radiation, no research has been conducted so far in vivo on the genotoxic effects of ELF-MF combined with X-rays. Aim and methods Aim of this study was to investigate in somatic and germ cells the effects of chronic ELF-MF exposure from mid gestation until weaning, and any possible modulation produced by ELF-MF exposure on ionizing radiation-induced damage. Mice were exposed to 50 Hz, 65 μT magnetic field, 24 hours/day, for a total of 30 days, starting from 12 days post-conception. Another group was irradiated with 1 Gy X-rays immediately before ELF-MF exposure, other groups were only X-irradiated or sham-exposed. Micronucleus test on blood erythrocytes was performed at multiple times from 1 to 140 days after birth. Additionally, 42 days after birth, genotoxic and cytotoxic effects on male germ cells were assessed by comet assay and flow cytometric analysis. Results ELF-MF exposure had no teratogenic effect and did not affect survival, growth and development. The micronucleus test indicated that ELF-MF induced a slight genotoxic damage only after the maximum exposure time and that this effect faded away in the months following the end of exposure. ELF-MF had no effects on ionizing radiation (IR)-induced genotoxicity in erythrocytes. Differently, ELF–MF appeared to modulate the response of male germ cells to X-rays with an impact on proliferation/differentiation processes. These results point to the importance of tissue specificity and development on the impact of ELF-MF on the early stages of life and indicate the need of further research on the molecular mechanisms underlying ELF-MF biological effects.

Abstract
We have performed a series of experiments applying high voltage between two electrodes, immersed in two beakers containing bidistilled water in a way similar to experiments conducted by Fuchs and collaborators, which showed that a water bridge can be formed between the two containers. We also observed the formation of water bridge. Moreover, choosing different pairs of electrodes depending on the material they are made up of, we observed that copper ions flow can pass along the bridge if the negative electrode is made up of copper. We show that the direction of the flux not only depends on the applied electrostatic field but on the relative electronegativity of the electrodes too. These results open new perspectives in understanding the properties of water. We suggest a possible explanation of the obtained results.

Abstract
Several years ago just before Christmas, in a small meeting room at the Institute of Pharmacology at the University of Rome, we had the opportunity to attend a meeting on "The role of QED in medicine" by Emilio Del Giudice and Giuliano Preparata. Before that meeting, we were more oriented towards a mechanistic view of Biochemistry and Medicine, believing that chemical reactions could only take place when a random collision between molecules with a gain in energy takes place. We envisioned water as just a solvent in which was possible to dissolve a solute. After we listened to Giuliano's and Emilio's speech on the "New physics of water", and on "The possible origin of coherence in cell, tissues and the interaction of very weak and low frequency magnetic fields with the ions, systems of the cell", we realized that living organisms are complex electrochemical systems which evolved in a relatively narrow range of well-defined environmental parameters. Environmental natural electro-magnetic fields are an ubiquitous factor in nature. If nature gave certain organisms the ability to receive information about the environment via invisible electromagnetic signals, then there must also the capability to discriminate between significant and meaningless ones. Bearing in mind that electromagnetic fields can be perceived by living organisms by means a resonance effect, we should not be amazed if they can be able to induce different biological effects. The work that we will present in memory of Emilio is based on the hypotheses that an aqueous system a chemical differentiation agent such as retinoic acid (RA) were electronically captured and transferred to the culture medium of Neuroblastoma Cell Line (LAN-5) and the proliferation rate was assessed to assess cell responses to the electromagnetic information transfer through the aqueous system. Like those enfolded in living organisms could play a synergic role in modulating biological functions, generating dissipative structures under appropriate patterns of electromagnetic signals providing basis for storing and retrieving biological activities. An external electro-magnetic stimulus from a source molecule can be stored, translated, and transferred by the aqueous systems to the biological target, selectively driving their endogenous activity and mimicking the effect of a source molecule.

Abstract
SUMMARY Aims: To evaluate the in vitro effects of extremely low-frequency magnetic field (ELF-MF) on growth and biofilm formation by Staphylococcus aureus, Pseudomonas aeruginosa, Burkholderia cepacia and Stenotrophomonas maltophilia strains from cystic fibrosis patients. Materials & methods: The motion of selected ions (Fe, Ca, Cu, Zn, Mg, K, Na) was stimulated by the ion resonance effect, then influence on growth and biofilm formation/viability was assessed by spectrophotometry or viability count. Results: Generally, exposure to ELF-MF significantly increased bacterial growth and affected both biofilm formation and viability, although with differences with regard to ions and species considered. Conclusion: Exposure to ELF-MF represents a possible new approach for treatment of biofilm-associated cystic fibrosis lung infections.

Abstract
In regenerative medicine finding a new method for cell differentiation without pharmacological treatment or gene modification and minimal cell manipulation is a challenging goal. In this work we reported a neuronal induced differentiation and consequent reduction of tumorigenicity in NT2 human pluripotent embryonal carcinoma cells exposed to an extremely low frequency electromagnetic field (ELF-EMF), matching the cyclotron frequency corresponding to the charge/mass ratio of calcium ion (Ca(2+)-ICR). These cells, capable of differentiating into post-mitotic neurons following treatment with Retinoic Acid (RA), were placed in a solenoid and exposed for 5 weeks to Ca(2+)-ICR. The solenoid was installed in a μ-metal shielded room to avoid the effect of the geomagnetic field and obtained totally controlled and reproducible conditions. Contrast microscopy analysis reveled, in the NT2 exposed cells, an important change in shape and morphology with the outgrowth of neuritic-like structures together with a lower proliferation rate and metabolic activity alike those found in the RA treated cells. A significant up-regulation of early and late neuronal differentiation markers and a significant down-regulation of the transforming growth factor-α (TGF-α) and the fibroblast growth factor-4 (FGF-4) were also observed in the exposed cells. The decreased protein expression of the transforming gene Cripto-1 and the reduced capability of the exposed NT2 cells to form colonies in soft agar supported these last results. In conclusion, our findings demonstrate that the Ca(2+)-ICR frequency is able to induce differentiation and reduction of tumorigenicity in NT2 exposed cells suggesting a new potential therapeutic use in regenerative medicine.

Abstract
OBJECTIVES The purpose of this study was to investigate the effects of increasing dose of intracoronary adenosine on fractional flow reserve (FFR) measurement. BACKGROUNDS FFR is a validated method for the assessment of the severity of coronary artery stenosis. It is based on the change in the pressure gradient across the stenosis after the achievement of maximal hyperemia of the coronary microcirculation that may be obtained by either intracoronary bolus or intravenous infusion of adenosine. No study has explored so far the effects of very high doses of intracoronary adenosine on FFR. METHODS FFR was assessed in 46 patients with 50 intermediate lesions during cardiac catheterization by pressure-recording guidewire (PrimeWire, Volcano, San Diego, California). FFR was calculated as the ratio of the distal coronary pressure to the aortic pressure at hyperemia. Increasing doses of adenosine were administrated (60, 120, 180, 360, and 720 μg) as intracoronary boluses. Exclusion criteria were: 1) allergy to adenosine; 2) baseline bradycardia (heart rate <50 beats/min); 3) hypotension (blood pressure <90 mm Hg); and 4) refusal to provide signed informed consent. RESULTS High doses of intracoronary adenosine were well tolerated, with no major side effects. Increasing doses up to 720 μg progressively decreased FFR values and increased the percentage of patients showing an FFR <0.75. Among angiographic parameters, both percent stenosis and lesion length were independently associated with lower FFR values. CONCLUSIONS This study shows that high doses of intracoronary adenosine (up to 720 μg) increased the sensitivity of FFR in the detection of hemodynamically relevant coronary stenoses. Furthermore, lesion length and stenosis severity were independent angiographic determinants of FFR.

Abstract
Even though platelet volume has been supposed to be indicator of platelet activation, contrasting results have been reported on its relationship with the extent of coronary artery disease (CAD). No data have been so far reported on Platelet-Large Cell Ratio (P-LCR). Thus, the aim of the current study was to investigate whether P-LCR is associated with CAD. We measured P-LCR in 1882 consecutive patients undergoing coronary angiography. Significant CAD was defined as stenosis >50% in at least 1 coronary vessel. We additionally measured Carotid Intima-Media Thickness (IMT) in 359 patients. The relationship between P-LCR and platelet aggregation was evaluated by PFA-100 and Multiplate. Patients with higher P-LCR were older (P = 0.038), with larger prevalence of diabetes (P < 0.0001), dilated cardiomyopathy or valvular heart disease (P = 0.004) and less often family history of CAD (P = 0.045), more often on statins (P = 0.002), and diuretics (P = 0.016). P-LCR was significantly associated with baseline glycaemia (P = 0.001) and RBC count (P < 0.001), but inversely related to platelet count (P < 0.0001). P-LCR was not associated with the prevalence of CAD (adjusted P = 0.3) or its severity. In addition, P-LCR was not related to Carotid IMT or platelet aggregation in patients with or without aspirin therapy. This study showed that P-LCR is not related to platelet aggregation, aspirin resistance, the extent of CAD and carotid IMT. Thus, P-LCR can not be considered as a marker of platelet reactivity or a risk factor for CAD.

Abstract
Electromagnetic fields are an assessed cause of prolonging free radicals lifespan. This study was carried out to investigate the influence of extremely low frequency electromagnetic fields on protein oxidation and on the 20S proteasome functionality, the complex responsible for the degradation of oxidized proteins. Caco 2 cells were exposed, for 24-72 hours, to 1 mT, 50 Hz electromagnetic fields. The treatment induced a time-dependent increase both in cell growth and in protein oxidation, more evident in the presence of TPA, while no changes in cell viability were detected. Exposing the cells to 50 Hz electromagnetic fields caused a global activation of the 20S proteasome catalytic components, particularly evident at 72 hours exposure and in the presence of TPA. The finding that EGCG, a natural antioxidant compound, counteracted the field-related pro-oxidant effects demonstrates that the increased proteasome activity was due to an enhancement in intracellular free radicals.

Abstract
Human skin cell culture (HaCaT) that has been exposed to an AC magnetic field undergoes detectable changes in its biochemical properties and shapes. Such changes were observed by infrared wavelength-selective scanning near-field optical microscopy with a resolution of 80-100 nm. We specifically investigated the changes in the distribution of the inner chemical functional groups and in the cell morphology induced by a 24 h exposure to a 1 mT (rms), 50 Hz sinusoidal magnetic field in a temperature regulated solenoid. These results further accentuate the crucial questions, raised by several recent studies, about the impact of low-frequency electromagnetic field on human cells.

Abstract
Electromagnetic therapy is a treatment method in which an electromagnetic or magnetic stimulus is used to achieve physiological changes in the body. The specific aim of the present work concerns the effectiveness of low frequency electromagnetic fields to modify the biochemical properties of human keratinocytes (HaCaT). Cells exposed to a 7 Hz 100 microT electromagnetic field for one hour (twice daily), indicated modification in shape and morphology. These modifications were also associated with different actin distribution as revealed by phalloidin fluorescence analysis. Indirect immunofluorescence with fluorescent antibodies against involucrin and beta-Catenin, both differentiation and adhesion markers, revealed an increase in involucrin and beta-Catenin expression, supporting the conclusion that exposure to electromagnetic field carries keratinocytes to an upper differentiation level. This study confirms our previous observation and supports the hypothesis that 7 Hz electromagnetic field, may modify cell biochemistry interfering in the differentiation and cellular adhesion of normal keratinocytes.

Abstract
One of the main problems of bioelectromagnetics - the unbelievable narrow resonance peaks at the cyclotron frequency of the alternating magnetic field - was considered. Modern electrodynamics of condensed matter clearly brings out that the reason of this phenomenon is extremely low viscosity within coherence domains of aqueous electrolytic solutions. The electrochemical model of action of combined static and alternating magnetic fields on aqueous solutions of amino acids is proposed. The possibility of arising a succession of changes in ionic forms in these processes was revealed. The dipole ions (zwitterions) together with water molecules electrostatically forming joint groups in the solution, create favorable conditions for arising mixed coherence domains there. Simultaneously with evolution of the coherent processes in these domains, the amino acid zwitterions are transforming into the usual ionic form, fit for cyclotron resonance. The development of cyclotron resonance under action of combined magnetic fields increases the ion kinetic energy, and the ions leave the domains for the incoherent component of the solution according to Del Giudice pattern (Comisso et al., 2006; Del Giudice et al., 2002), creating the peak current through the solution. Then the ions are transforming little by little into zwitterionic form again; after that, the solution becomes ready to react on exposure of magnetic fields again. The possibilities for formation of coherence domains composed of water molecules together with peptide molecules or protein ones are discussed.

Abstract
Investigations into the ion cyclotronic resonance (ICR) in living matter confront the so called Zhadin effect (12), whose explanation is not fully achieved. Several attempts have been done to explain this phenomenon, the most interesting of which is based on Quantum Electrodynamics (18): the molecules of water, the ions and the biomolecules form extended mesoscopic regions, called Coherence Domains (CD), where they oscillate in unison between two selected levels of their spectra in tune with a self-produced coherent E.M. field having a well defined frequency, dynamically trapped within the CD. Moreover, it is possible, to induce, by an external applied field (either hydrodynamical or EM) or also by a chemical stimulation, coherent excitations of CD's that give rise to electric currents circulating without friction within the CD's: as a consequence magnetic fields are produced. A resonating magnetic field thus is able to extract the ions from the orbit and push them in the flowing current. Electrochemical investigation of the system suggested that the observed phenomenon involves the transitory activation of the anode due to ICR, followed by anode passivation due to the adsorption of amino acid and its oxidation products (18). This hypothesis induced us to investigate an alternate configuration of the experiment, removing the electrolytic cell and submitting a flask containing the solution into a condenser to be exposed to the proper ICR. Temperature and variable parameters involved in the effect have been investigated in order to overcome the randomness of the effect.
