Abstract
INTRODUCTION Kidney transplantation (KTx) necessarily conveys an ischemia/reperfusion (I/R) process, which impacts on allograft outcomes. Delayed graft function (DGF) is defined as a non-decrease of serum creatinine by at least 10% daily on 3 consecutive days during the first 7 days post-KTx. DGF significantly conditions both short- and long-term graft outcomes. Still there is a lack of DGF predictive biomarkers. OBJECTIVES This study aimed to explore the potential of kidney graft perfusate metabolomics to predict DGF occurrence. METHODS 49 human perfusates from grafts categorized upon donor type [donation after brain death (DBD)/donation after circulatory death (DCD)] and DGF occurrence and 19 perfusates from a murine model classified upon death type (DBD/DCD) were collected and analyzed by NMR-based metabolomics. RESULTS The multivariate analysis of the murine data highlighted significant differences between perfusate metabolomes of DBD versus DCD. These differences were similarly observed in the human perfusates. After correcting for the type of donor, multivariate analysis of human data demonstrated a metabolomics signature that could be correlated with DGF occurrence. CONCLUSIONS The metabolome of kidney grafts is influenced by the donor's type in both human and pre-clinical studies and could be correlated with DGF in the human DBD cohort. Thus, metabolomic analysis of perfusate applied prior to KTx may represent a new predictive tool for clinicians in a more personalized management of DGF. Moreover, our data paves the way to better understand the impact of donor's types on the biochemical events occurring between death and the hypothermic storage.

Abstract
Non-small cell lung cancer (NSCLC) represents 85% of all new lung cancer diagnoses and presents a high recurrence rate after surgery. Thus, an accurate prediction of recurrence risk in NSCLC patients at diagnosis could be essential to designate risk patients to more aggressive medical treatments. In this manuscript, we apply a transfer learning approach to predict recurrence in NSCLC patients, exploiting only data acquired during its screening phase. Particularly, we used a public radiogenomic dataset of NSCLC patients having a primary tumor CT image and clinical information. Starting from the CT slice containing the tumor with maximum area, we considered three different dilatation sizes to identify three Regions of Interest (ROIs): CROP (without dilation), CROP 10 and CROP 20. Then, from each ROI, we extracted radiomic features by means of different pre-trained CNNs. The latter have been combined with clinical information; thus, we trained a Support Vector Machine classifier to predict the NSCLC recurrence. The classification performances of the devised models were finally evaluated on both the hold-out training and hold-out test sets, in which the original sample has been previously divided. The experimental results showed that the model obtained analyzing CROP 20 images, which are the ROIs containing more peritumoral area, achieved the best performances on both the hold-out training set, with an AUC of 0.73, an Accuracy of 0.61, a Sensitivity of 0.63, and a Specificity of 0.60, and on the hold-out test set, with an AUC value of 0.83, an Accuracy value of 0.79, a Sensitivity value of 0.80, and a Specificity value of 0.78. The proposed model represents a promising procedure for early predicting recurrence risk in NSCLC patients.

Abstract
AIMS The interaction between common cardiovascular risk factors (CVRF) and hypertrophic cardiomyopathy (HCM) is poorly studied. We sought to explore the relation between CVRF and the clinical characteristics of patients with HCM enrolled in the EURObservational Research Programme (EORP) Cardiomyopathy registry. METHODS AND RESULTS 1739 patients with HCM were studied. The relation between hypertension (HT), diabetes (DM), body mass index (BMI), and clinical traits was analysed. Analyses were stratified according to the presence or absence of a pathogenic variant in a sarcomere gene. The prevalence of HT, DM, and obesity (Ob) was 37, 10, and 21%, respectively. HT, DM, and Ob were associated with older age (P<0.001), less family history of HCM (HT and DM P<0.001), higher New York Heart Association (NYHA) class (P<0.001), atrial fibrillation (HT and DM P<0.001; Ob p = 0.03) and LV (left ventricular) diastolic dysfunction (HT and Ob P<0.001; DM P = 0.003). Stroke was more frequent in HT (P<0.001) and mutation-positive patients with DM (P = 0.02). HT and Ob were associated with higher provocable LV outflow tract gradients (HT P<0.001, Ob P = 0.036). LV hypertrophy was more severe in Ob (P = 0.018). HT and Ob were independently associated with NYHA class (OR 1.419, P = 0.017 and OR 1.584, P = 0.004, respectively). Other associations, including a higher proportion of females in HT and of systolic dysfunction in HT and Ob, were observed only in mutation-positive patients. CONCLUSION Common CVRF are associated with a more severe HCM phenotype, suggesting a proactive management of CVRF should be promoted. An interaction between genotype and CVRF was observed for some traits.

BACKGROUND & PURPOSE. Left atrial function (LAF) is a determinant of clinical status and outcome in many cardiac disorders, including cardiac amyloidosis (CA). Aim of this study is to explores the LAF in CA and other cardiomyopathies with hypertrophic phenotype, and its consequences on cardiovascular haemodynamics, right ventricular function and survival.
METHODS. We enrolled 50 patients with CA (26 AL and 24 wtATTR) and 75 with hypertrophic phenotype (LVH group) [25 hypertrophic cardiomyopathy (HCM) pts, 25 hypertensive pts (HypCM), and 25 pts with aortic stenosis (AS)]. LAF was analysed using the phasic method [LAEI as reservoir, LAPEF as conduit, LAAEF as active pump and TLAEF as total emptying function; see figure 1] by LA volumes determination.
RESULTS. ATTR patients showed higher LA dimensions and impaired reservoir and total LA emptying function (TLAEF) compared to AL without differences LAF. Compared to the LVH group, CA patients showed higher LA dimension with impaired LAF in all phasic parameters, higher LV filling pressures and reduced biventricular function. We further divided CA and LVH patients into four subgroups based on the presence or absence of LA dysfunction (LADys+ for TLAEF values below the median: <50.2%; range 9.3-70.9%]. Among the groups, patients with CA/LADys+ showed worst clinical status, higher pulmonary pressures (sPAP) and lower TAPSE and TAPSE/sPAP ratio values. After a median follow-up of 24 months, 19 patients died from cardiovascular (CV) causes (15 in CA/LADys+ group and 4 in LVH/LADys+). The overall survival free of CV death was 64% in CA/LADys+ and 85% in LVH/LADys+ (4/26) group [log-rank χ2 29.6; p < 0.0001]. A sequential multivariate model was employed to assess whether LAF could predict CV deaths: TLAEF was entered together with established clinical and echocardiographic parameters (NYHA functional class, LAVI, E/Em, sPAP, TAPSE and TAPSE/sPAP ratio). At the final backward analysis, LAVI, TAPSE/sPAP and TLAEF were independent prognosticators of CV death.
CONCLUSIONS. LAF is significantly more impaired in CA than LVH group and is associated with worst clinical status, RV dysfunction and higher LV filling and pulmonary pressure. Moreover, LADys is a frequent feature of CA and significantly associated with higher CV mortality. We suggests that LADys in LVH group could results from chronic pressure overload due to LA"s exposure to high LV diastolic pressure (impaired LV compliance). In CA, LADys could also be determined by direct LA infiltration. The pathophysiological result is a progressive LA remodelling with increased LA pressure, consequent backward transmission to the pulmonary venous system and, ultimately, RV dysfunction. TLAEF is parameter of LAF that correlates with increased pulmonary vascular resistance (measured elsewhere with cardiac catheterisation) and RV dysfunction. In CA, it seems promising as marker of the haemodynamic consequences of LADys and CV mortality. Abstract Figure 1 Abstract Figure 2

BACKGROUND & PURPOSE. Cardiac amyloidosis (CA) is an infiltrative disorder characterized by left ventricular (LV) thickening with early systolic and diastolic dysfunction. Due to it poor prognosis, and the beneficial impact of novel treatments when started in early stages of disease, its forward detection is crucial. Aim of this study is comparing the diagnostic accuracy of classical and novel echocardiographic parameters in detecting CA among other forms of genetic and non-genetic cardiomyopathies with hypertrophic phenotype.
METHODS. We enrolled 50 pts with CA (26 AL and 24 wtATTR) and 75 phenocopies (LVH group) [25 hypertrophic cardiomyopathy (HCM) pts, 25 hypertensive (HypCM) pts, and 25 pts with non-severe aortic stenosis (AS)]. Standard and novel LV morpho-functional echo parameters [LV ejection fraction (LVEF), myocardial contraction fraction (MCF), global longitudinal strain (GLS), relative regional strain ratio (RRSR), ejection fraction on strain ratio (EFSR)], and novel Myocardial Work (MW) parameters [Global Work Index (GWI), Global Constructive Work (GCW), Global Wasted Work (GWW), Global Work Efficiency (GWE)] were analyzed.
RESULTS. LV standard, novel and MW-derived systolic parameters were more impaired in CA compared to LVH group. At ROC curve analysis, GCW showed the best performance in discriminating CA from other forms of LVH (AUC 0.886; 95% CI: 0.819-0.954; P < 0.0001), with a cut-off value < 1473 mmHg% showing 90% of sensitivity and 82% of specificity). At linear regression analysis, GCW correlated with many echocardiographic parameters (IVSD, PWD, RWT ratio, LVMi, MCF, LVESV, LVEF, EFSR and RRSR). At multivariate analysis, PWD (P < 0,029) and RWT ratio (p < 0,014) were the only parameters associated with GCW. At 24 months follow-up, there were 15 deaths in CA and 4 in LVH group. At Kaplan-Meier analysis the overall survival free of cardiovascular death was reduced in the lowest GCW interquartile ranges (log-rank χ2 21.5; p < 0.0001). At Cox hazard ratio analysis, GCW was the only prognostic parameter associated with cardiovascular mortality (β 1.006; 95% CI: 1.003-1.009; P < 0.0001).
CONCLUSIONS. Despite CA and LVH patients shows a similar phenotype, the systolic function differs greatly. In the present study, the GCW showed the best ability in detecting CA among other forms of LVH. Its reduction in CA seems reflect the infiltrative burden and its consequences on myocardial deformation properties, while its reduction in LVH group has been attributed elsewhere to fibrotic derangement. GCW showed to be a promising novel diagnostic and prognostic factor in this setting. Abstract Figure 1 Abstract Table 1

BACKGROUND & PURPOSE. Right ventricular (RV) dysfunction in cardiomyopathies is a consequence of chronic overload (i.e. aortic stenosis, AS) or direct involvement of systemic disorders (i.e. cardiac amyloidosis, CA). The Tricuspid Annular Plane Systolic Excursion/Systolic Pulmonary Artery Pressure (TAPSE/sPAP) ratio has been recently proposed as a surrogate of RV-arterial coupling (RVAC). This study aims to compare RVAC between CA subgroups and between CA and other forms of genetic and non-genetic cardiomyopathies with hypertrophic phenotype.
METHODS. We enrolled 50 patients with CA (26 AL and 24 wtATTR) and 75 cardiomyopathies with hypertrophy phenotype (LVH group) [25 pts with hypertrophic cardiomyopathy (HCM), 25 hypertensive pts(HypCM), and 25 pts with AS]. Besides routine echocardiographic measurements, we analysed right chambers dimensions and classical and novel parameters of RV function [TAPSE, TAPSE/sPAP, St wave, global (RVGLS) and free-wall (RVFWS) strain].
RESULTS. Compared to AL, the ATTR group showed higher right chambers dimensions, without differences in all RV systolic parameters. Compared to the LVH group, CA patients showed no differences in RV dimensions while RV systolic parameters, including the TAPSE/sPAP ratio, were significantly reduced in the presence of significantly higher LV filling pressures. At ROC curve analysis, TAPSE (AUC 0.877; 95% CI: 0.811-0.943; p < 0,0001) and TAPSE/sPAP ratio (AUC 0.859; 95% CI: 0.783-0.935; p < 0,0001) showed the best ability in discriminating CA among other forms of LVH (cut-off 20.5 mm for TAPSE with sensibility of 80.5% and specificity of 78.8%, respectively; cut-off 0.62 for TAPSE/sPAP ratio with sensibility of 85.4% and specificity 81.8%). At 24 months follow-up, there were 15 deaths in CA (30%) and 4 in LVH group (5%). At Kaplan-Meier estimation, the TAPSE/sPAP ratio showed progressively a significantly reduced survival in the lowest interquartile ranges. Moreover, at multivariate analysis, TAPSE/sPAP was the only independent prognostic factor (β -5,644; 95% IC: 0,000-0,522; p < 0,027).
CONCLUSIONS. The RVAC is significantly impaired in CA compared to the LVH group but not between CA subgroups. Its reduction seems attributable to both increase LV filling pressure, due to the restrictive nature of the infiltrative cardiomyopathy, and reduced RV systolic function, due to either indirect RV chronic overload and direct myocardial infiltration. The TAPSE/sPAP ratio is a surrogate of RVAC and proved to be a novel echocardiographic parameter useful in both discriminating CA among genetic and non-genetic forms of LVH, and stratifying the prognosis.

Abstract
Abstract
Background
Left ventricular hypertrophy (LVH) in infants of diabetic mothers (IDMs) has been generally considered a benign condition, which usually regresses as the stimulus for the insulin production disappears, resulting in normalized left ventricular wall thickness in the 6 months of life. However, these conclusions have been based on small, mostly outdated cohort studies. Indeed, it has been recently shown that increased left ventricular mass persists in late infancy (6 to 12 months), long after the intrauterine exposure has been removed, suggesting that other factors may potentially contribute.
Purpose
This study sought to describe the characteristics and the natural course of LVH in a well-characterized consecutive cohort of IDMs.
Methods
Sixty consecutive IDMs with LVH have been retrospectively identified and enrolled in the study. All IDMs were evaluated at baseline and every 6 months until LV wall thickness regression, defined as the decrease of wall thickness measurement into the normal reference range for cardiac parameters (z-score >−2 and <2). A comprehensive assessment was performed in those patients with diagnostic markers suggestive of a different cause and/or without significant reduction of the LVH during follow-up.
Results
At 1-year follow-up, all IDMs showed a significant reduction of maximal wall thickness (MWT) (MWT-mm: 6.67±2.37 vs. 5.83±1.70, p-value<0.001; MWT-z-score: 6.67±4.71 vs. 2.39±2.55, p-value<0.001) and left ventricular outflow tract (LVOT) gradient (15.35±15.58 vs. 11.22±8.14, p-value<0.004), compared to baseline, and all patients showed LV wall thickness regression or residual mild or moderate LVH (57%, 28%, and 12%, respectively) (Figure 1), except 2 patients with persistent severe LVH, that after a comprehensive clinical-genetic assessment were diagnosed as Noonan syndrome with multiple lentigines.
At multivariate analysis, MWT was significantly associated with LV wall thickness regression at 1-year follow-up (MWT-mm: OR 0.48 [0.29–0.79], p-value=0.004; MWT-z-score: OR 0.71 [0.56–0.90], p-value=0.004) in an inversely proportional fashion.
Overall, 59%, 72% and 79% of IDMs with LVH showed a complete LV wall thickness regression at 1-year, 2-year and 3-year follow-up, respectively (Figure 2). Excluding the two patients with a different cause of LVH, all IDMs showed a LV wall thickness regression in the first 6 years of life.
Conclusions
LVH in IDMs represents a benign condition with complete regression during the first years of life. In those patients without LV wall thickness regression, combined with clinical markers suggesting a specific disease, a complete work-up is required for a definite diagnosis.

Abstract
The authors report on a consecutive series of 62 evaluable, elderly (age > 69 years) women with primary operable breast cancer treated only with tamoxifen. The treatment schedule was 160 mg on day 1 followed by a daily maintenance dose of 20 mg. Compliance to treatment was excellent, and subjective side effects were minimal. The best response achieved after at least 6 months of treatment was complete in 7, partial in 22 and minor in 3, whereas stable disease or progression was observed in 28 and 2 patients, respectively. The response rate decreased and progressions increased with time. At 6, 12, 24, 36 and 48 months of treatment, the complete + partial response rates were 30.6 %, 45 %, 45.6 %, 38.7 % and 25% and the progressive disease rates 4.8%, 19.6%, 34.8%, 45.2 % and 66.6 %, respectively. These results do not confirm some previous reports of a high response to tamoxifen. This difference is only partially explained by the use of mammography, which is more sensitive than palpation, to assess tumor size and treatment response. The present study does not support primary hormone therapy as a current alternative to surgery, which should be the standard treatment in otherwise healthy elderly patients with operable breast cancer.

Abstract
The risk of developing breast cancer was investigated in 339 patients in whom histologically confirmed intraductal papilloma had been surgically removed. Follow-up ranged from 2 to 14 years, (average, 6.62 years). Ten breast cancers were observed, whereas 3 were expected on the basis of age-specific incidence rates drawn from local cancer registries (relative risk = 3.33, 95% confidence interval = 1.60-6.13). No significant difference in the relative risk was observed as far as papilloma type (single or multiple) was concerned. All breast cancers observed occurred in the same breast as the papilloma. Women in whom a benign intraductal papilloma has been excised should be carefully followed since they at are higher risk for ipsilateral breast cancer.

Abstract
DNA is widely used as a target for GMO analysis because of its stability and high detectability. Real-time PCR is the method routinely used in most analytical laboratories due to its quantitative performance and great sensitivity. Accurate DNA detection and quantification is dependent on the specificity and sensitivity of the amplification protocol as well as on the quality and quantity of the DNA used in the PCR reaction. In order to enhance the sensitivity of real-time PCR and consequently expand the number of analyzable target genes, we applied a preamplification technique to processed foods where DNA can be present in low amounts and/or in degraded forms thereby affecting the reliability of qualitative and quantitative results. The preamplification procedure utilizes a pool of primers targeting genes of interest and is followed by real-time PCR reactions specific for each gene. An improvement of Ct values was found comparing preamplified vs. non-preamplified DNA. The strategy reported in the present study will be also applicable to other fields requiring quantitative DNA testing by real-time PCR.

Abstract
Efficient vaccination against viral agents requires a strong T-cell-mediated immune response to clear viral-infected cells. Optimal vaccination can be achieved by administration of recombinant viral vectors encoding phatogen antigens. Adenoviral vectors have attracted considerable attention as potential viral vectors for genetic vaccination owing to their favorable safety profile and potent transduction efficiency following intramuscular injection. However, the neutralizing antibody response against adenoviral capsid proteins following adenoviral vectors injection limits the success of vaccination protocols based on multiple administrations of the same adenoviral serotype. In this work, we describe efficient immunization of rhesus macaques, the preferred model for preclinical assessment, with an HCV candidate vaccine by heterologous priming-boosting with adenoviral vectors based on different serotypes. The induced responses are broad and show significant cross-strain reactivity. Boosting can be delayed for over 2 years after priming, indicating that there is long-term maintenance of resting memory cells.

Abstract
The neural retina is a highly organized organ whose final histoarchitecture depends on the presence of diverse growth factors and on their interactions with extracellular matrix components. However, the role of growth factors on retinal development is not fully understood. Suramin has been shown to produce diverse cellular effects via the simultaneous block of the action of several growth factors. We have therefore studied the effects of suramin on organotypic culture of chick embryo neural retina in order to gain further insights into the participation of growth factors in neural retinal development. Neural retina was incubated for 24 h with suramin at 50-200 microM and then processed to determine cell proliferation, nuclear morphology, and actin distribution. Suramin provoked extensive morphological changes revealed by a decrease in BrdU incorporation, alterations in cellular organization, and disruption of the outer limiting membrane, with the emergence of cellular elements through it. All of these effects were dose-dependent and markedly attenuated by the simultaneous presence of suramin and fibroblast growth factor 2 (FGF-2) in the culture medium. These findings indicate that suramin induces pleiotropic effects on the histoarchitecture of the chicken neural retina in organ culture and suggest that FGF-2 is one of the biological modulators involved in the maintenance of the structural organization of the chicken neural retina.

Abstract
We have investigated the localization of basic fibroblast growth factor (bFGF) binding sites during the development of the neural retina in the chick embryo. The specificity of the affinity of bFGF for its receptors was assessed by competition experiments with unlabelled growth factor or with heparin, as well as by heparitinase treatment of the samples. Two different types of binding sites were observed in the neural retina by light-microscopic autoradiography. The first type, localized mainly to basement membranes, was highly sensitive to heparitinase digestion and to competition with heparin. It was not developmentally regulated. The second type of binding site, resistant to heparin competition, appeared to be associated with retinal cells from the earliest stages studied (3-day-old embryo, stages 21-22 of Hamburger and Hamilton). Its distribution was found to vary during embryonic development, paralleling layering of the neural retina. Binding of bFGF to the latter sites was observed throughout the retinal neuroepithelium at early stages but displayed a distinct pattern at the time when the inner and outer plexiform layers were formed. During the development of the inner plexiform layer, a banded pattern of bFGF binding was observed. These bands, lying parallel to the vitreal surface, seemed to codistribute with the synaptic bands existing in the inner plexiform layer. The presence of intra-retinal bFGF binding sites whose distribution varies with embryonic development suggests a regulatory mechanism involving differential actions of bFGF on neural retinal cells.

Abstract
The authors investigated the association between mammographic parenchymal patterns and breast cancer risk by a case control study. Three-hundred and thirty-four cancers, either screen or interval detected in the course of a screening program, were assumed as cases and compared to 668 non-cancer controls matched by age, residence and date of screening examination. Parenchymal patterns were classified by retrospective blind review of randomly mixed films by two independent readers. A high agreement was achieved on a two-group scale (N1-P1 vs P2-DY) inter and intraobserver consistency being 0.94 and 0.95, respectively. The relative risk of breast cancer exposure (RR) with respect to N1 pattern was 1.99 for P1, 3.59 for P2 and 4.18 for DY patterns. The RR of P2-DY with respect to N1-P1 patterns was 2.62. The results did not change after stratification by age group. Parenchymal patterns do not seem to be a reliable criterion for selecting high risk women for screening as in this series only 57% of all cancers occurred in high risk (P2-DY) subjects.

Abstract
Anaphylaxis is a systemic reaction which can be very dangerous in many patients. In addition to the most common antigens (drugs, venoms, foods), physical exercise can provoke anaphylaxis in the sensitized patients. The mechanism of this reaction is still unknown. In this report, we describe a case of exercise-induced anaphylaxis in a 25 year old female who had experienced two syncopal attacks during strong physical activity. On other occasions she had noticed that prolonged work would cause urticaria, pruritus and numbness. During hospitalization, on two occasions a treadmill stress test induced bronchial spasm, urticaria and hypotension. We believe that the association of urticaria and anaphylaxis would suggest the possible presence of a vasoactive substance released from the mast-cells and basophil leucocytes.

Abstract
Lenses in organ culture permit an analysis of factors acting on epithelial cell growth, while keeping the normal steric constraints of the cell population. By employing this technique with radioautography of epithelial whole mounts, we showed that the DNA synthesis found in the epithelia of cultured bovine lenses follows an organized spatial and temporal pattern during culture. Within the first 48 h, active cells were located at the preequatorial region ("germinative zone"), a distribution consistent with the in vivo spatial organization of multiplying cells. Starting at about 48 h, cells from the central region of the epithelium--a nonproliferating population--were triggered to synthesize DNA in the presence of eye-derived growth factor (EDGF). When cultured in serum-free medium, only a small fraction of the cells was labeled, but when a low serum concentration was present, this fraction reached 50% of the cell population. The stimulatory effect of EDGF required a lag period, but its effect reached a maximum exceeding that found for serum. However, the cells from the germinative region, having a cell density three- to four-fold higher than the central region, were not stimulated to proliferate. This occurred irrespective of the presence of EDGF or serum. If this growth-stimulatory activity derived from the retina were the actual factor controlling cell proliferation in the lens in vivo, then the results presented here would point to the presence of a regulatory mechanism similar to that known for some other hormones.
