Abstract
BACKGROUND The aim of our study was to evaluate the role of intravascular macrophages in the diagnosis of early and late antibody-mediated rejection (AMR) on endomyocardial biopsies (EMBs). METHODS We reviewed 1,420 consecutive EMBs from 131 patients and selected 75 C4d+ EMBs. The C4d+ group was compared with a control group (66 patients) matched for age, gender, date of transplantation, follow-up, immunosuppressive regimen and primary heart disease. A total of 141 EMBs were evaluated. Immunoperoxidase staining for C4d and CD68 were performed. Post-transplant IgG anti-HLA reactivity was investigated by Luminex technology. Clinical data were also collected. Fourteen EMBs were available from 11 symptomatic AMR patients. RESULTS Of the 141 EMBs evaluated, 53 were positive for intravascular macrophages (CD68); among them, 32 were also positive for C4d (32 of 53, 60.4%). Of the 88 CD68- EMBs, 43 were also C4d+ (43 of 88, 48.9%). Of the 53 CD68+ EMBs, 30 EMBs were within the first year since transplantation (30 of 53, 57.8%), and among these 21 were also positive for C4d (21 of 30, 70.0%). In the late period, among the 23 CD68+ EMBs (23 of 53, 42.2%) 11 were also positive for C4d (11 of 23, 47.8%). In the early period, intravascular macrophages were more common in symptomatic (3 of 3, 100%) than asymptomatic (3 of 11, 27.3%) patients. Sensitivity and specificity of intravascular macrophages in predicting donor-specific antibodies (DSA) within the first year were 50.0% and 100.0%, respectively. CONCLUSIONS Intravascular macrophages predict C4d, DSA and symptoms early after transplantation; however, in the late period, they are unable to identify patients with circulating DSA, C4d and/or symptoms.

Abstract
Aircraft de-icing fluids (ADF) are a source of water and soil pollution in airport sites. Propylene glycol (PG) is a main component in several commercial formulations of ADFs. Even though PG is biodegradable in soil, seasonal overloads may result in occasional groundwater contamination. Feasibility studies for the biostimulation of PG degradation in soil have been carried out in soil slurries, soil microcosms and enrichment cultures with and without the addition of nutrients (N and P sources, oligoelements), alternative electron acceptors (nitrate, oxygen releasing compounds) and adsorbents (activated carbon). Soil samples have been taken from the contaminated area of Gardermoen Airport Oslo. Under aerobic conditions and in the absence of added nutrients, no or scarce biomass growth is observed and PG degradation occurs by maintenance metabolism at constant removal rate by the original population of PG degraders. With the addition of nutrient, biomass exponential growth enhances aerobic PG degradation also at low temperatures (4 ° C) that occur at the high season of snowmelt. Anaerobic PG degradation without added nutrients still proceeds at constant rate (i.e. no biomass growth) and gives rise to reduced fermentation product (propionic acid, reduced Fe and Mn, methane). The addition of nitrate does not promote biomass growth but allows full PG mineralization without reduced by-products. Further exploitation on the field is necessary to fully evaluate the effect of oxygen releasing compounds and adsorbents.

Abstract
e19086 Background: In the last few years, the treatment of non-small cell lung cancer (NSCLC) has been dramatically changed with the introduction of EGFR TK (Epidermal Growth Factor Tyrosine Kinase) inhibitors. Given its objectivity and the benefits derived by patients, overall survival (OS) has been historically considered the most important therapeutic objective in advanced NSCLC. However, little is known about postprogression survival (PPS) in NSCLC. This study evaluates the correlation between response to erlotinib and post progression survival (i.e. the time between disease progression and death) to estimate the impact of this drug on overall survival. Methods: We retrospectively analyzed 68 NSCLC unselected patients consecutively treated with second or third line erlotinib at our institution from 2007 to 2010, including in the responder group patients who progressed after stable disease on erlotinib for at least six months (n=20). The relationship between OS and PPS was evaluated by standard statistical tests. P-values <0.05 were considered statistically significant. Results: Survival was significantly prolonged in responders patients (18.6 vs 11.3) suggesting the important role of EGFR TK inhibitors in NSCLC management. In addition a significant increase of PPS was recorded in these patients (9.1 vs 4.6 p=0.02), allowing to perform further therapy lines to better control cancer evolution. Conclusions: These data underline the key role of EGFR in NSCLC growth and progression and the impact of erlotinib in cancer control evolution. Post progression therapy influence the effect on overall survival. This analysis suggests that a treatment strategy incorporating all active agents over the course of disease optimizes OS. Further investigations will be needed in selected patients harboring EGFR-activating mutations to better define the role of PPS as new indicator of erlotinib efficacy.

Abstract
We report the case of a 68-year-old woman who underwent heart transplantation for hypertrophic cardiomyopathy. Two months after the transplant she developed mild fever and dyspnea with a marked drop in left ventricle ejection fraction of 31%. Coronary angiography was negative for cardiac allograft vasculopathy. Endomyocardial biopsy revealed ischemic damage with no evidence of acute cellular rejection, antibody-mediated rejection or viral myocarditis. A neoplastic process was suspected even though full-body computerized tomography was negative for malignancy. The patient died 4 months after transplantation. The autopsy showed acute antero-septal myocardial infarction due to a nodular epicardial EBV-related posttransplant lymphoproliferative disorder (PTLD) infiltrating the left anterior descending coronary artery with occlusive neoplastic thrombosis. We highlight two major aspects of this case: (1) the unusual occurrence of early PTLD involving the cardiac allograft and causing a fatal outcome, (2) the application of an immunological technique for HLA-DRB1 typing to posttransplant paraffin-embedded autopsy material to identify the recipient origin of this early malignancy, thus excluding a possible donor-transmitted neoplasm.

Abstract
Little is known about specific IL-23 alterations associated with breast cancer and the data available are still controversial. Therefore, the evaluation of changes in serum IL-23 levels may add further information on the role of this cytokine in breast cancer patients. The aim of this study was to evaluate prospectively the prognostic importance of circulating IL-23 in patients with untreated breast cancer, respect to healthy controls, and the association with clinico-pathological variables. The study involved 50 women diagnosed with stages I-IV breast cancer and 38 healthy controls. Of the 50 breast cancer patients, 37 women were recruited prior to their initial adjuvant chemotherapy and 13 prior to receive first line chemotherapy for metastatic disease. Adjuvant chemotherapy patients were at least in their 4th week post-surgery. IL-23 serum concentrations were measured by a quantitative enzyme immunoassay technique. We found a statistically significant higher systemic cytokine value in women with cancer in comparison with the control group (14.52±11.39 pg/ml vs. 6.35±4.63 pg/ml, P<0.0001). Patients with shorter overall survival presented higher IL-23 values, suggesting a negative prognostic correlation. There was no significant differences in IL-23 levels among patients according to the biomolecular characteristics, the different subtypes and the presence of metastatic disease. This work investigated, for the first time, the role of IL-23 in breast cancer patients showing a significant increase respect the control group. However, further validations are needed in larger studies to better investigate the implications of IL-23 increase in these patients.

Abstract
Giant field enhancement and field singularities are a natural consequence of the commonly employed local-response framework. We show that a more general nonlocal treatment of the plasmonic response leads to new and possibly fundamental limitations on field enhancement with important consequences for our understanding of surface-enhanced Raman spectroscopy (SERS). The intrinsic length scale of the electron gas serves to smear out assumed field singularities, leaving the SERS enhancement factor finite, even for geometries with infinitely sharp features. For silver nanogroove structures, mimicked by periodic arrays of half-cylinders (up to 120 nm in radius), we find no enhancement factors exceeding 10 orders of magnitude (10(10)).

Abstract
Until recently, few therapeutic options were available for patients with castration-resistant prostate cancer (CRPC). Since 2010, four new molecules with a demonstrated benefit (sipuleucel-T, cabazitaxel, abiraterone, and denosumab) have been approved in this setting, and to-date several other agents are under investigation in clinical trials. The purpose of this review is to present an update of targeted therapies for CRPC. Presented data are obtained from literature and congress reports updated until December 2011. Targeted therapies in advanced phases of clinical development include novel androgen signaling inhibitors, inhibitors of alternative signaling pathways, anti-angiogenic agents, inhibitors that target the bone microenvironment, and immunotherapeutic agents. Radium-223 and MDV3100 demonstrated a survival advantage in phase III trials and the road for their introduction in clinical practice is rapidly ongoing. Results are also awaited for phase III studies currently underway or planned with new drugs given as monotherapy (TAK-700, cabozantinib, tasquinimod, PROSTVAC-VF, ipilimumab) or in combination with docetaxel (custirsen, aflibercept, dasatinib, zibotentan). The optimal timing, combination, and sequencing of emerging therapies remain unknown and require further investigation. Additionally, the identification of novel markers of response and resistance to these therapies may better individualize treatment for patients with CRPC.

Abstract
Transforming growth factor-β1 (TGF-β1) is a neurotrophic factor that exerts neuroprotective effects against β-amyloid-induced neurodegeneration. Recently, a specific impairment of the TGF-β1 signaling pathway has been demonstrated in Alzheimer's disease (AD) brain. TGF-β1 is also involved in the pathogenesis of depressive disorders, which may occur in 30-40% of AD patients. The TGF-β1 gene contains single nucleotide polymorphisms (SNPs) at codon +10 (T/C) and +25 (G/C), which are known to influence the level of expression of TGF-β1. We investigated TGF-β1 +10 (T/C) and +25 (G/C) SNPs and allele frequencies in 131 sporadic AD patients and in 135 healthy age- and sex-matched controls. Genotypes of the TGF-β1 SNPs at codon +10 (T/C) and +25 (G/C) did not differ between AD patients and controls, whereas the allele frequencies of codon +10 polymorphism showed a significant difference (P = 0.0306). We also found a different distribution of the +10 (C/C) phenotype (continuity-corrected χ(2) test with one degree of freedom = 4.460, P = 0.0347) between late onset AD (LOAD) patients and controls (P = 0.0126), but not between early onset AD (EOAD) patients and controls. In addition, the presence of the C/C genotype increased the risk of LOAD regardless of the status of apolipoprotein E4 (odds ratio [OR] = 2.34; 95% CI = 1.19-4.59). Compared to patients bearing the T/T and C/T polymorphisms, LOAD TGF-β1 C/C carriers also showed > 5-fold risk to develop depressive symptoms independently of a history of depression (OR = 5.50; 95% CI = 1.33-22.69). An association was also found between the TGF-β1 C/C genotype and the severity of depressive symptoms (HAM-D(17) ≥ 14) (P < 0.05). These results suggest that the CC genotype of the TGF-β1 gene increases the risk to develop LOAD and is also associated with depressive symptoms in AD.

Abstract
We study the effect of nonlocal optical response on the optical properties of metallic nanowires, by numerically implementing the hydrodynamical Drude model for arbitrary nanowire geometries. We first demonstrate the accuracy of our frequency-domain finite-element implementation by benchmarking it in a wide frequency range against analytical results for the extinction cross section of a cylindrical plasmonic nanowire. Our main results concern more complex geometries, namely cylindrical and bow-tie nanowire dimers that can strongly enhance optical fields. For both types of dimers we find that nonlocal response can strongly affect both the field enhancement in between the dimers and their respective extinction cross sections. In particular, we give examples of blueshifted maximal field enhancements near hybridized plasmonic dimer resonances that are still large but nearly two times smaller than in the usual local-response description. For the same geometry at a fixed frequency, the field enhancement and cross section can also be significantly more enhanced in the nonlocal-response model.

Abstract
Size distribution and selected element concentrations of atmospheric particulate matter (PM) were investigated in the Venice Lagoon, at three sites characterised by different anthropogenic influence. The PM(10) samples were collected in six size fractions (10-7.2, 7.2-3.0, 3.0-1.5, 1.5-0.95; 0.95-0.49 and <0.49 μm) with high volume cascade impactors, and the concentration of 17 elements (Al, As, Ca, Cd, Co, Cu, Fe, K, Li, Mg, Mn, Na, Ni, Pb, Sr, V, Zn) was determined by inductively coupled plasma quadrupole mass spectroscopy. More than 1 year of sampling activities allowed the examination of seasonal variability in size distribution of atmospheric particulates and element contents for each site. At all the stations, particles with an aerodynamic diameter <3 μm were predominant, thus accounting for more than 78% of the total aerosol mass concentration. The highest PM(10) concentrations for almost all elements were found at the site which is more influenced by industrial and urban emissions. Similarity in size distribution of elements at all sites allowed the identification of three main behavioural types: (a) elements found mainly within coarse particles (Ca, Mg, Na, Sr); (b) elements found mainly within fine particles (As, Cd, Ni, Pb, V) and (c) elements with several modes spread throughout the entire size range (Co, Cu, Fe, K, Zn, Mn). Factor Analysis was performed on aerosol data separately identified as fine and coarse types in order to examine the relationships between the inorganic elements and to identify their origin. Multivariate statistical analysis and assessment of similarity in the size distribution led to similar conclusions on the sources.

Abstract
Due to the shortage of organ donors, heart transplantation cannot be offered to many infants with end-stage heart failure; this issue leads to mortality rates of 30-50% in patients in the paediatric age group awaiting operation. ABO-incompatible heart transplantation has been performed safely with no particular or invasive preparatory procedures other than plasma exchange during cardiopulmonary bypass for removing preformed antibodies, with no reports of hyperacute rejection. We report our first clinical experience of heart transplantation on a 2-month-old-infant (blood group O), diagnosed with intracardiac tumour, in which the donor was a 19-day-old newborn of blood group A. Sharing the know-how about ABO-incompatible heart transplantation in newborns and infants awaiting transplantation will help in decreasing mortality among this group of patients.

Abstract
The purposes of this study were to validate the use of a single standard question for the rapid screening of restless legs syndrome (RLS) and to analyze the eventual effects of the presence of RLS on self-assessed daytime sleepiness, global clinical severity and cognitive functioning. We evaluated a group of 521 consecutive patients who accessed our neurology clinic for different reasons. Beside the answer to the single question and age, sex, and clinical diagnosis, the following items were collected from all patients and normal controls: the four criteria for RLS, the Epworth Sleepiness Scale (ESS), the Clinical Global Impression of Severity (CGI-S), and the Mini-Mental State evaluation. RLS was found in 112 patients (70 idiopathic). The single question had 100% sensitivity and 96.8% specificity for the diagnosis of RLS. ESS and CGI-S were significantly higher in both RLS patient groups than in normal controls. RLS severity was significantly higher in idiopathic than in associated/symptomatic RLS patients. RLS can be screened with high sensitivity and good reliability in large patient groups by means of the single question; however, the final diagnosis should always be confirmed by the diagnostic features of RLS and accompanied by a careful search for comorbid conditions.

Abstract
BACKGROUND Twenty years after the first successful pediatric heart transplantation (HTx), the long-term outcome of this population is still unknown. Current study analyzes our results in pediatric HTx population. METHODS AND RESULTS Between 1985 and 2005, we performed 604 HTx. Forty-three patients (7%) were less than 18-years old and six patients were less than 1-year old. Mean age at HTx was 9.7+/-6.3 years (38 days-18 years). Indications were: cardiomyopathy in 33 patients (76%), congenital in 9 (21%), tumor in 1 (3%). Chronic immunosuppression was Cyclosporine A and Azathioprine-based. Overall survival at Kaplan-Meier analysis (CI 95%) was 82.5% at 1-year post-HTx, 73.5% at 5 years, 72.2% at 10 years, 62.1% at 15 years, and 49.3% at 20 years, respectively. We had 14 deaths (32%): 7 within the first year after HTx (early mortality, EM), 7 occurred later (late mortality, LM). Causes of EM were: graft failure (43%), acute rejection (43%) and post transplant lymphoproliferative disease (14%). Causes of LM were: neoplasms (57%), infection (28%), graft vasculopathy (15%). At late follow-up, cardiac function, somatic and psycoaffective development were normal. Fifteen patients (34%) developed neoplasms, nine patients (21%) hypertension, and three patients (8%) developed kidney dysfunction. Neoplasms were found to be an independent predictor of outcome (p=0.039) (OR=7). CONCLUSIONS Overall survival in the pediatric population is better than adults' population (62.1 vs 48% at 15 years after HTx). Neoplasms were the main comorbidities and causes of LM: at multivariate analysis, their incidence was related with hematic Cyclosporine A levels after 10 years from HTx (p=0.01).
