Abstract
OBJECTIVE To report cross-sectionally serum levels of 25-hydroxyvitamin D [25(OH)D] in women living in Italy within 12 months from breast cancer (BC) diagnosis. METHODS Baseline data were obtained from 394 women diagnosed with primary BC, enrolled from 2016 to 2019 in a lifestyle trial conducted in Italy. Subjects' characteristics were compared between two 25(OH)D concentrations (hypovitaminosis D<20 and ≥20 ng/mL) with the Chi-squared test or Fisher's exact test for small-expected counts. Using multiple logistic regression-adjusted models, we estimated odds ratios (ORs) of hypovitaminosis D with 95% confidence intervals (CIs) in the total sample and in the unsupplemented subgroup. RESULTS Hypovitaminosis D was found in 39% of all subjects, 60% in unsupplemented subjects, and 10% in supplemented subjects. Increasing ORs of hypovitaminosis D were found with increasing body mass index, 25-30, >30, and ≥35 versus <25 kg/m2 (ORs: 2.50, 4.64, and 5.81, respectively, in the total cohort and ORs: 2.68, 5.38, and 7.08 in the unsupplemented); living in the most southern Italian region (OR 2.50, 95%CI 1.22-5.13); and with hypertriglyceridemia (OR 2.46; 95%CI 1.16-5.22), chemotherapy history (OR 1.86, 95%CI 1.03-3.38), and inversely with anti-estrogenic therapy (OR 0.43, 95%CI 0.24-0.75) in the total sample. CONCLUSIONS Hypovitaminosis D in women recently diagnosed with BC and participating in a lifestyle trial in Italy was widespread and highest with obesity, hypertriglyceridemia, and chemotherapy use. Considering that hypovitaminosis D is a risk factor for lower efficacy of bone density treatments and possibly BC mortality, our results suggest the need to promptly address and treat vitamin D deficiency.

Abstract
Amyloid deposition within stenotic aortic valves (AVs) also appears frequent in the absence of cardiac amyloidosis, but its clinical and pathophysiological relevance has not been investigated. We will elucidate the rate of isolated AV amyloid deposition and its potential clinical and pathophysiological significance in aortic stenosis (AS). In 130 patients without systemic and/or cardiac amyloidosis, we collected the explanted AVs during cardiac surgery: 57 patients with calcific AS and 73 patients with AV insufficiency (41 with AV sclerosis and 32 without, who were used as controls). Amyloid deposition was found in 21 AS valves (37%), 4 sclerotic AVs (10%), and none of the controls. Patients with and without isolated AV amyloid deposition had similar clinical and echocardiographic characteristics and survival rates. Isolated AV amyloid deposition was associated with higher degrees of AV fibrosis (p = 0.0082) and calcification (p < 0.0001). Immunohistochemistry analysis suggested serum amyloid A1 (SAA1), in addition to transthyretin (TTR), as the protein possibly involved in AV amyloid deposition. Circulating SAA1 levels were within the normal range in all groups, and no difference was observed in AS patients with and without AV amyloid deposition. In vitro, AV interstitial cells (VICs) were stimulated with interleukin (IL)-1β which induced increased SAA1-mRNA both in the control VICs (+6.4 ± 0.5, p = 0.02) and the AS VICs (+7.6 ± 0.5, p = 0.008). In conclusion, isolated AV amyloid deposition is frequent in the context of AS, but it does not appear to have potential clinical relevance. Conversely, amyloid deposition within AV leaflets, probably promoted by local inflammation, could play a role in AS pathophysiology.

Abstract
BACKGROUND The subsequent waves of the COVID-19 pandemic in Italy had a major impact on cardiac care. METHODS A survey to evaluate the dynamic changes in arrhythmia care during the first five waves of COVID-19 in Italy (first: March-May 2020; second: October 2020-January 2021; third: February-May 2021; fourth: June-October 2021; fifth: November 2021-February 2022) was launched. RESULTS A total of 127 physicians from arrhythmia centers (34% of Italian centers) took part in the survey. As compared to 2019, a reduction in 40% of elective pacemaker (PM), defibrillators (ICD), and cardiac resynchronization devices (CRT) implantations, with a 70% reduction for ablations, was reported during the first wave, with a progressive and gradual return to pre-pandemic volumes, generally during the third-fourth waves, slower for ablations. For emergency procedures (PM, ICD, CRT, and ablations), recovery from the initial 10% decline occurred in most cases during the second wave, with some variability. However, acute care for atrial fibrillation, electrical cardioversions, and evaluations for syncope showed a prolonged reduction of activity. The number of patients with devices which started remote monitoring increased by 40% during the first wave, but then the adoption of remote monitoring declined. CONCLUSIONS The dramatic and profound derangement in arrhythmia management that characterized the first wave of the COVID-19 pandemic was followed by a progressive return to the volume of activities of the pre-pandemic periods, even if with different temporal dynamics and some heterogeneity. Remote monitoring was largely implemented during the first wave, but full implementation is needed.

Abstract
Abstract
Background
Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia, occurring in 1–2% of the general population. Patients affected by AF have an increased risk of stroke and heart failure and European guidelines recommend catheter ablation of AF in symptomatic patients refractory to antiarrhythmic therapy. In elderly patients, the AF ablation procedure is associated with a higher rate of overall complications. Recently, stereotactic arrhythmia radioablation (STAR) with precise high-dose of radiation was used to treat ventricular arrhythmias.
Purpose
No data were reported in literature about the use of Linac-based STAR, so a prospective phase-II trial was designed to evaluate safety of Linac-based STAR in elderly patients with paroxysmal AF.
Methods
Fourteen patients (mean age 78±6 years; 57% male) were enrolled in the study. All patients had symptomatic paroxysmal AF refractory to antiarrhythmic drugs. All patients performed 1-week ECG-Holter monitoring (ECG-HM) and transthoracic echocardiogram before and after STAR. Primary end-point was defined as all the adverse events of special interest related to STAR treatment; secondary end-point was defined as AF recurrence after the treatment. The study was approved by the local Ethics Committee and all patients signed informed consent.
Results
All patients performed STAR with a mean overall treatment time of 3 minutes. No serious adverse events were documented acutely and after 6 months of follow up. Transthoracic echocardiogram did not show cardiac damage after STAR. The 1-week ECG-HM performed before STAR documented symptomatic AF episodes in all patients. The 1-week ECG-HM performed 1-month after procedure documented frequent symptomatic atrial ectopy and atrial tachycardias without AF recurrences. The 1-week ECG-HM performed 3 and 6 months after procedure did not revealed AF recurrences. Two patients had a single episode of sustained atrial tachycardia 6 months after STAR. Both patients performed a left atrial mapping using CARTO system and Pentaray mapping catheter documenting PV isolation without vein stenosis (figure); no phrenic nerve damage was documented in both patients. All patients had an improvement in quality of life.
Conclusion
Our preliminary data reported for the first time that the LINAC-based STAR approach could represent a valid alternative to perform PVI in elderly patients with paroxysmal AF.

Abstract
PURPOSE There is emerging evidence that radiomics analyses can improve detection of skeletal fragility. In this cross-sectional study, we evaluated radiomics features (RFs) on computed tomography (CT) images of the lumbar spine in subjects with or without fragility vertebral fractures (VFs). METHODS Two-hundred-forty consecutive individuals (mean age 60.4 ± 15.4, 130 males) were evaluated by radiomics analyses on opportunistic lumbar spine CT. VFs were diagnosed in 58 subjects by morphometric approach on CT or XR-ray spine (D4-L4) images. DXA measurement of bone mineral density (BMD) was performed on 17 subjects with VFs. RESULTS Twenty RFs were used to develop the machine learning model reaching 0.839 and 0.789 of AUROC in the train and test datasets, respectively. After correction for age, VFs were significantly associated with RFs obtained from non-fractured vertebrae indicating altered trabecular microarchitecture, such as low-gray level zone emphasis (LGLZE) [odds ratio (OR) 1.675, 95% confidence interval (CI) 1.215-2.310], gray level non-uniformity (GLN) (OR 1.403, 95% CI 1.023-1.924) and neighboring gray-tone difference matrix (NGTDM) contrast (OR 0.692, 95% CI 0.493-0.971). Noteworthy, no significant differences in LGLZE (p = 0.94), GLN (p = 0.40) and NGDTM contrast (p = 0.54) were found between fractured subjects with BMD T score < - 2.5 SD and those in whom VFs developed in absence of densitometric diagnosis of osteoporosis. CONCLUSIONS Artificial intelligence-based analyses on spine CT images identified RFs associated with fragility VFs. Future studies are needed to test the predictive value of RFs on opportunistic CT scans in identifying subjects with primary and secondary osteoporosis at high risk of fracture.

Background
Recent advances support the concept that pre-persistent Atrial Fibrillation (AF) does not explain the wholeness of embolic strokes, suggesting the recently postulated hypothesis of a broad Atrial Cardiomyopathy (AC). In contrast to its worldwide distribution and its very inclusive definition, pathogenic mechanisms underlying AC are still largely unknown. Folate cycle disorders (FCD) are a yet underrated dysmetabolism only partly explained by methylene tetrahydrofolate reductase (MTHFR)-inherited defects. On a translational basis, FCD could hinder both endothelial and circulating endothelial progenitor cell (EPCs) functioning, therefore providing one-shot explanation to both atrial stasis (increasing atrial fibrosis and generating atrial hypocontractility) and endothelial dysfunction (ED). If such cardiac-bone marrow networking would be verified, a fundamental pathogenic mechanism of AC and subsequent AF would be unraveled.
Purpose
This study aims to enquire for the hypothesis that: 1) atrial fibrosis (AFib) would relate to FCD (intended as both: a)MTHFR C677T inherited mutations and b)bone-marrow function disorders, here referring to erythropoiesis diversions) and 2) AF patients would show dysfunctional EPCs.
Methods
We studied 59 consecutive patients admitted to the Cardiology Unit of the General Hospital "F.Miulli", with preserved EF, subjected to AF ablation. AFib was quantified by relative % of low-voltage (<0,5 mV) bipolar peak-to-peak points, with respect to the wholeness of the endocavitary mapping. Blood count cell was evaluated. MTHFR C677T genotypes were elucidated by RT-PCR. Folate were measured by a commercial laboratory test. EPCs isolation and characterization were performed by Ficoll-Hypaque gradient and flow cytometry analysis for cell surface antigens: CD45, CD34, CD133, VEGFR2 and KDR. EPCs functional wound healing assay was performed.
Results
Baseline characteristics did not differ between Sample and Control groups (Fig. 1 – Left Table). % of Afib significantly differs between C677T MTHFR homozigosis patients (n=15) with respect to non-C677T MTHFR homozygosis patients (n=44) (Fig.1 – Right graph. - p < 0,02). Once univariate analysis was performed, subsequent multivariate analysis highlights highest fit once merged RBC, RDW-SD and folates values were inputed: Goodness of fit was proper, modelling good (Fig.2 – superior graph. - R2=0,39; p=0,0001). Either RBC, RDW-SD and folates coefficient reached significance (p < 0,0001; p < 0,01; p < 0,05 respectively). Number of EPCs significantly differs between AF patients and matched controls (Fig 2 – inferior graph. – p < 0,001).
Conclusions
Our findings support the hypothesis that genetically determined folates dysmetabolism (MTHFR dysfunction) promotes AFib via a complex cardiac-bone marrow networking involving circulating EPCs and unraveled by erythropoiesis diversions. Such results suggest a pathogenic role of folate cycle disorders in the AC development.

Abstract
Abstract
Background/Introduction
The inspIRE clinical trial was designed to assess the safety and efficacy of a fully integrated biphasic pulsed field ablation (PFA) system comprised of a multi-channel generator, variable decapolar irrigated loop circular catheter, and mapping system (Figure A) for the treatment of paroxysmal atrial fibrillation (PAF).
Purpose
Using this novel PFA system in a multicentre clinical trial, we present the initial feasibility of electrical pulmonary vein isolation (PVI), procedural performance, and acute safety results.
Methods
inspIRE is a prospective, non-randomized, multi-centre study, planned to enrol up to 550 patients. PVI is performed with the novel, variable loop circular catheter, compatible mapping system and generator. Acute procedural effectiveness (entrance block in all clinically targeted PVs post adenosine/isoproterenol challenge) and the incidence of primary adverse events (PAEs) were assessed. PAEs are defined as the occurrence of cardiac tamponade/perforation, myocardial infarction, stroke/cerebrovascular accident, thromboembolism, transient ischemic attack, permanent phrenic nerve paralysis, pulmonary edema, pericarditis, and any major vascular access complications within 7 days of the ablation procedure. Additionally, any incidence of procedure or device related death, atrio-esophageal fistula, or PV stenosis (related to the ablation procedure or study catheter) within the 12M follow-up period is classified as a PAE.
Results
A total of 35 PAF subjects (age 59.7±10.7 years, 54.3% male) were treated across 5 European sites by 6 operators. Acute procedural success was achieved in 100% of study subjects (Figure B) with zero incidence of PAEs. Mean total procedure time was 82.9±19.9 minutes with 27.0±11.9 minutes of PFA from first to last application. Average fluoroscopy use was 10.6±6.8 minutes and LA dwell time was 45.6±15.3 minutes.
Conclusion
Initial results of the inspIRE trial demonstrate the acute safety and effectiveness of the new integrated IRE circular catheter, mapping system and generator for PVI in PAF patients.

Abstract
OBJECT To analyze geometrical approaches, prescription modalities, and delivery efficiency for linear accelerator (Linac)-based STereotactic Arrhythmia Radioablation (STAR) for ventricular tachycardia. METHODS The anatomy and planning target volume (PTV) of the first Italian STAR patient were used. To assess geometrical approaches, 3 plans prescribed to 75% isodose-line, differing for number, length of arcs, and couch rotations, were generated and compared (Plans#1-3). Volumetric-arc with 6-MV flattening-filter-free (FFF) was employed. To evaluate prescription modality and delivery, the best geometrical plan was compared with other plans prescribed on 70%, 65%, and 60% isodose-line and with another one using 10MV-FFF beams (Plans#4-7). RESULTS For Plans#1-3, PTV coverage, mean cardiac dose, monitor units (MUs), and beam-delivery-time (BDT) were 96-98.5%, 4.9-5.2 Gy, 7047-7790, and 5-6 min, respectively. Plans#4-7 were similar in terms of mean cardiac dose, MUs and BDT to Plans#1-3, except in maximum dose and lower time for 10MV-FFF plan. CONCLUSION Linac-based STAR is safe and efficient in terms of BDT and MUs. To ensure high dose to PTV, different dose prescription modalities should be evaluated. The 10FFF approach was the faster but not suitable in patient with cardiac implantable electronic devices.

Abstract
Abstract
Background
Patients with atrial fibrillation (AF) and severe chronic kidney disease (CKD) are at higher risk of both bleeding and thromboembolic events. Non-vitamin K antagonist oral anticoagulants (NOACs) are licensed to be used in these patients, although they were excluded from phase III controlled randomized trials comparing NOACs vs warfarin in AF. Thus, current evidence on NOACs use in such setting of patients is not definitive.
Purpose
Aim of our multicenter study was to perform a real-world comparison of clinical outcome with NOACs vs vitamin K antagonist anticoagulants (VKAs) also in AF patients having an estimated glomerular filtration rate (eGFR) 15–29 mL/min.
Methods
We retrospectively included a total of 266 patients receiving NOACs (N=159) or VKAs (N=107). Primary outcome measure was the cumulative incidence of the net composite endpoint including ischemic stroke, systemic thromboembolism or any bleeding. Mean follow-up was 2.6 years.
Results
CHA2DS2-VASc and HAS-BLED scores at baseline were similar in the two groups (3.4±1.3 with NOACs vs 3.4±0.9 with VKAs and 3.1±1.0 vs 3.0±0.7, respectively); eGFR and hemoglobin values were also comparable (31.8±12.3 vs 32±11.9 mL/min and 10.2±2.1 vs 11.0±2.3 g/dL, respectively). NOACs were not inferior to VKAs for the primary net composite endpoint: incidence 20.7% vs 29.9%, p<0.01 for non-inferiority, p=0.11 for superiority. In proportional Cox regression model, hazard ratio for the primary outcome measure with NOACs use was 0.74 (95% CI 0.45–1.21, p=0.22). In the NOAC group there was a trend towards reduction in minor bleeding complications (p=0.08).
Conclusions
Our real-world data indicate that in patients with AF and severe renal failure NOACs are not inferior to VKAs for both safety and efficacy. The use of NOACs was associated with a numerically lower incidence of minor bleeding.

Abstract
This is the first study to report on the biocompatible and immunogenic properties of one-pot synthesised gold and silver nanoparticles (Au@UI and Ag@UI) using the macroalgae Ulva intestinalis (UI). The UI aqueous extract, Au@UI, and Ag@UI were obtained under sterile conditions and fully characterized by UV-vis spectroscopy, TEM, HRTEM, STEM and FTIR spectroscopy. Moreover, for the first time, the composition of carbohydrates in the UI extract has been reported along with the changes observed after nanoparticle synthesis by size exclusion chromatography, in order to investigate their possible role in the biosynthetic process. This study suggested that the polysaccharide fraction of the extract is involved in the formation and stabilization of the nanoparticles. The potential toxicity of the samples was evaluated using different cell lines and the hemocompatibility was tested in mouse erythrocytes. In addition, ROS production, complement activation and cytokine release were evaluated to determine the immunogenicity. The results showed that Au@UI and Ag@UI exhibit good biocompatibility and hemocompatibility, with the exception of Ag@UI nanoparticles at high concentration, which were hemolytic. The samples induced ROS release and complement activation, two key mechanisms in innate immunity. The samples also induced the release of cytokines from Th1 and Th2 profiles, and other cytokines implicated in the activation of the immune system. Au@UI and Ag@UI were biocompatible and preserved the immunostimulant properties of the UI extract. Hence, Au@UI and Ag@UI could be useful as adjuvants in vaccine development and promote a balanced Th1 and Th2 immune response mediated by ROS production, cytokine release and complement activation.

In the RADIANCE feasibility study of the balloon catheter, all enrolled patients who underwent ablation were screened for SCL using pre- and post-procedural diffusion-weighted MRI. Several modifications were made to the ablation workflow in a subsequent European registration study (SHINE) of the same catheter: eliminating dual transseptal access, using an over-the-wire mini lasso, continuously irrigating all side ports, bolus dosing with heparin before transseptal puncture, maintaining activated clotting time (ACT) at 350–400 sec, and setting a maximum temperature limit of 55°C (previously, 60–65°C). Interim data are presented for SHINE (data cutoff, 22 Oct 2018).
Results
In the neurological assessment evaluable (NAE) populations of RADIANCE (n=38) and SHINE (n=30), respectively, mean ages were 60.8±10.04 and 59.7±7.83 years, and 57.9% and 70.0% were male. One patient in each study had a history of TIAs. SCL incidences were 23.7% (10 lesions in 9 patients) in RADIANCE and 7.1% (2 lesions in 2 patients) in SHINE (excluding 1 SCL that occurred in a patient who failed to meet inclusion criteria [age>75] and 1 SCL that occurred after data cut-off). SHINE NAE enrollment has since completed with no further SCL occurrences. Overall, mean ACTs were 344.3±24.55 sec in RADIANCE and 381.6±73.31 sec in SHINE (p=0.01); in patients with SCL, mean ACTs were 349.3±25.65 and 417.8±87.33 sec, respectively.
Conclusion(s)
Modifications to the workflow led to a decrease in the SCL incidence for PAF ablation using the novel RF balloon catheter.

Abstract
Abstract
Background/Introduction
The novel catheter with 6 thermocouples for real-time temperature monitoring during irrigated radiofrequency ablation was designed to potentially enhance safety and effectiveness of the Smart Touch Surround Flow (STSF) catheter by incorporating real-time temperature sensing. A supplementary, novel algorithm was developed to modulate power to maintain target temperature during high power/short duration ablation (90W, 4s).
Purpose
This sub-analysis was performed to examine consistency and reproducibility of the procedural efficiencies and acute success of the novel catheter with optimized temperature control and microelectrodes in treating paroxysmal atrial fibrillation (PAF) across multiple sites from two initial feasibility studies, in standard (QMODE) and high power/short duration (QMODE+) temperature-control ablation modes.
Methods
The QDOT-MICRO (QMODE, NCT02944968; N=42) and QDOT-FAST (QMODE+, NCT03459196; N=52) studies were both prospective, non-randomized multi-center, clinical investigations completed across 6 and 7 centers, respectively, in Europe. Procedural efficiencies and acute success (PVI via entrance block) was examined across sites within the study.
Results
In the QDOT-MICRO study, median procedure time (105–155 min), RF ablation time (27.7–39.5 min), and fluoroscopy times (2.2–8 min) during QMODE ablation were similar across the 6 sites. In QMODE+ ablation, median procedure time, RF ablation time, and fluoroscopy times all fall within (84–134 min), (4.8–9.7 min) and (1.1–9.6 min), respectively, across the 7 sites. Fluid delivery by the study catheter was low in both studies: QDOT-MICRO 547±278mL (mean ± SD); QDOT-FAST 382±299. mL (mean ± SD); which is 39.1 and 57.4% lower, respectively, than reported in the SMART SF trial. Esophageal temperature probe was used in the majority of patients (30/42 for QDOT MICRO and 51/52 for QDOT-FAST). Acute PVI was successful in 100% of patients in both studies with no deaths or unanticipated AEs.
Conclusion(s)
In both feasibility studies, procedural efficiencies were reproducible across study sites in both QMODE and QMODE+, with 100% acute success and good safety outcomes. Efficiencies are likely to improve with further experience. These results need to be confirmed in larger trials.

Abstract
OBJECTIVES To compare dynamic contrast-enhanced MRI (DCE-MRI) data obtained using different prebolus T1 values in glioma grading and molecular profiling. METHODS We retrospectively reviewed 83 cases of gliomas: 46 lower-grade gliomas (LGG; grades II and III) and 37 high-grade gliomas (HGG; grade IV). DCE-MRI maps of plasma volume fraction (Vp), extravascular-extracellular volume fraction (Ve), and tracer transfer constant from plasma to tissue (Ktrans) were obtained using a fixed T1 value of 1400 ms and a measured T1 obtained with variable flip angle (VFA). Tumour segmentations were performed and first-order histogram parameters were extracted from volumes of interest (VOIs) after co-registration with the perfusion maps. The two methods were compared using Wilcoxon matched-pairs signed-rank test and Bland-Altman analysis. Diagnostic accuracy was obtained and compared using ROC curve analysis and DeLong's test. RESULTS Perfusion parameters obtained with the fixed T1 value were significantly higher than those obtained with the VFA. As regards diagnostic accuracy, there were no significant differences between the two methods both for glioma grading and molecular classification, except for few parameters of both methods. CONCLUSIONS DCE-MRI data obtained with different prebolus T1 are not comparable and the definition of a prebolus T1 by T1 mapping is not mandatory since it does not improve the diagnostic accuracy of DCE-MRI. KEY POINTS • DCE-MRI data obtained with different prebolus T1 are significantly different, thus not comparable. • The definition of a prebolus T1 by T1 mapping is not mandatory since it does not improve the diagnostic accuracy of DCE-MRI for glioma grading. • The use of a fixed T1 value represents a valid alternative to T1 mapping for DCE-MRI analysis.

Abstract
Abstract
Background:Previous studies suggested a link between obesity, insulin-resistance and breast cancer outcome. The aim of the present prospective observational study was to investigate the role of metabolic syndrome (MetS) and its components on early breast cancer (EBC) patients' outcome.
Methods: MetS was defined by the presence of 3 to 5 of the following components: waist circumference (WC) > 88 cm, blood pressure ≥ 130/≥85 mmHg, serum levels of triglycerides (TG) ≥ 150 mg/dL, high-density lipoprotein (HDL) < 50 mg/dL and fasting glucose (FG) ≥ 110 mg/ dL (National Cholesterol Education Program Expert Panel on Detection, Evaluation, And Treatment of High Blood Cholesterol In Adults - NCEP-ATPIII criteria). Overall, 955 EBC patients were prospectively enrolled between January 2009 and December 2013 at University Hospital Federico II and National Cancer Institute G.Pascale, Naples, Italy. Clinical and tumor characteristics were collected for all the patients. A total of 494 patients (51.7%) had complete data on all the components of MetS at first diagnosis and thus were included in the current analysis. Study population was divided into 2 main groups: (1) patients with less than 3 components (No MetS); (2) patients with 3-5 components (MetS). Categorical variables were analyzed by the chi-square test and survival data by the log-rank test and Cox proportional hazards regression model.
Results: Overall 366 (74.1%) and 128 (25.9%) women were categorized as No MetS and MetS, respectively. MetS patients were more likely to be older and postmenopausal compared to No MetS patients. In detail, 46% vs 38% were older than 55 yrs (p<0.0001) and 87% vs 54% were postmenopausal (p<0.0001) in MetS vs No MetS groups, respectively. No statistically significant differences in tumor stage, type of adjuvant therapy or tumor subtypes defined by immunohistochemistry (IHC) were identified among the two groups. At univariate analysis, stage, tumor subtypes, TG and FG values, number of components of MetS, and presence of MetS were significantly associated to both disease free survival (DFS) and overall survival (OS). Age, BMI, WC, and HDL levels were correlated to OS only. At the multivariate Cox proportional hazards model (adjusted for age, menopausal status, stage, IHC subtypes and adjuvant therapy) MetS patients had numerically higher risk of relapse and significantly higher risk of death compared to No MetS patients [DFS hazard ratio (HR): 1.64 95% confidence interval (CI): 0.94-2.86, p=0.07 and OS HR: 3.83, 95% CI 1.7-6.77 p=0.001]. Additionally, of the 366 No MetS patients included in the analysis, 122 (33.3%) had 0 and 244 (66.7%) had “1 to 2” components of MetS. Interestingly, patients with “1 to 2” components of MetS had increased risk of dying compared to patients with 0 components (OS HR: 4.39, 95% CI:1.26-15.36, p=0.02) . No significant difference among these two groups was observed in terms of DFS.
Conclusions: MetS is correlated with poor outcome in EBC patients. Among patients without full criteria for MetS diagnosis, the presence of 1 or 2 components of the syndrome may predict for worse survival. Testing for components of MetS in BC patients is recomended to predict outcome and to eventually suggest lifestyle changes, exercise and diet.

Abstract
We used natural mercury (Hg) stable isotopes to investigate the Hg cycle in a rainforest soil catena (French Guiana) partially gold-mined during the early 1950s. Litterfall showed homogeneous Δ199Hg values [-0.18 ± 0.05‰, i.e., a modern gaseous elemental Hg (GEM) isotopic signature]. After litter decomposition, Hg bound to organic matter (OM) is mixed with Hg from pristine (-0.55 ± 0.22‰) or gold-mined (-0.09 ± 0.16‰) mineral materials. Negative Δ199Hg values in deep pristine mineral horizons (-0.60 ± 0.16‰) suggest the transfer of Hg bound to dissolved OM depleted in odd isotopes due to mass-independent fractionation during Hg abiotic reduction. Perennial palm tree leaves collected above gold-mined and pristine soil recorded contrasting Δ199Hg signatures likely resulting from GEM re-emission processes from soils and leaf surfaces. Upslope, soil δ202Hg signatures showed a negative shift (ε ∼ -1‰) with depth attributed to mass-dependent fractionation during Hg sorption and complexation onto iron oxides and dissolved OM. Downslope, higher δ202Hg values in soils resulted from hydromorphy [lower humification, greater Hg(II) reduction, etc.]. The unique Hg isotopic signatures of Amazonian soils probably result in multistep fractionation processes during pedogenesis (millions of years) and in a potentially different Hg isotopic signature of preanthropogenic background GEM.

Abstract
BACKGROUND AND AIM Over the last decades advances in understanding the molecular bases of the close relationship between nutrition, metabolism, and diseases have been impressive. However, there are always novel frontiers coming up and epigenetics is one of these. Sirtuins, are pivotal factors in the control of metabolic pathways according to nutrient availability. In the present study we evaluated the effect of nutrient deprivation on expression, DNA methylation and chromatin status of the sirtuin genes. METHODS AND RESULTS We performed these studies in mouse hepatoma cells, that were grown in standard medium, or in media containing low glucose concentration, or no glucose, or no amino acids. We applied quantitative real-time PCR to cDNA, methylation-enriched DNA and nuclease-treated DNA in order to evaluate gene expression, DNA methylation, and chromatin condensation, respectively. This study shows that the expression of sirtuin genes varies following nutrient deprivation. Moreover, we observed that changes of DNA methylation and chromatin condensation occur at the transcription start site of sirtuin genes following nutrient deprivation. CONCLUSIONS Epigenetic mechanisms may have a role in the sirtuin response to nutrient deprivations in cultured hepatoma cells. Replicating these results in vivo to achieve a comprehensive understanding of the epigenetic control of sirtuin expression following nutrient deprivations might open up novel therapeutic possibilities to cure metabolic diseases and promote human health.

Abstract
AIMS Mediterranean diet (MD) is acknowledged to exert a number of beneficial health effects. We assessed the efficacy and the durability of a 3-month intensive dietary intervention aimed at implementing the MD on body weight and cardiometabolic risk factors in subjects at high risk. METHODS One hundred and sixteen subjects participated in the study (71 assigned to the intensive intervention and 45 to the conventional intervention). The intensive intervention consisted of 12 weekly group educational meetings and a free-of-charge supply of meals prepared according to the MD model. The conventional intervention consisted of an individual education session along with monthly reinforcements of nutritional messages by the general practitioner. All participants were followed up for 9 months. RESULTS The two groups had similar pre-intervention characteristics. After the intervention, mean body weight decreased significantly in both groups (p < 0.001). However, the intervention group lost more weight (6.8 ± 4.0 vs. 0.7 ± 1.3, p < 0.0001) and showed a greater reduction in plasma glucose, triglycerides, blood pressure and an increase in HDL cholesterol than the control group (p < 0.01-p < 0.002). In the subgroup of participants with type 2 diabetes, there was a significant reduction in HbA1c level following the intensive (p < 0.0001) but not the conventional intervention. At follow-up, weight loss still persisted in the intervention group (p < 0.0001), while it was lost in the control group. Both interventions significantly reduced blood pressure in the long term (p < 0.001). A significant reduction in daily total energy intake was observed in both groups with a greater reduction in saturated fat and a higher increase in fibre intake in the intervention than in the control group (p < 0.009 and p < 0.001, respectively). CONCLUSIONS A 3-month intensive dietary intervention inspired to the traditional MD produced greater and more durable weight loss and improvement in cardiometabolic risk profile than the conventional intervention.

Abstract
The availability of a high molecular weight poly(L-lactide), with supposed good mechanical properties, encouraged us to carry out an in vivo experimental study to evaluate the degradation rate and accompanying loss of strength during interaction with bone. Small cylindrical PLLA rods were manufactured by compression moulding. Thirty-six male New Zealand rabbits (b.w. 3 kg), randomly divided into six groups of six animals each, were submitted to implantation of the rods under general anaesthesia (0 3x7 mm rods in the lateral condylic region of the right femur and 0 3x50 mm rods in the intracondylic channel of the left femur). The animals were then sacrificed at the end of each experimental time (4, 8, 12, 24, 52, 64 weeks), hence the femurs were explanted. Histology showed no inflammatory cells with fragmentation or resorption of bone trabeculae. Mechanical studies showed a decrease in mechanical properties and flexional stiffness, and the absence of evident material resorption. Finally, the properties of this newly developed resorbable device, when confirmed, seem to justify future clinical introduction of this synthetic material.

Abstract
Nowadays, with the increase of computational analysis in sciences such as biology and neuroscience, the computational aspect is one of the most challenging. The purpose of this work is the achieve the possibility to apply spatio-temporal networks inference techniques on brain to perform network analysis. One of the problems of spatio-temporal network applications is the computational time, and it becomes impractical to keep developing studies when it takes a long time to analyze and compute the results. We present a GPU-based system used to speed up the computation of spatio-temporal networks applied to different brain data; thanks to the architecture of these devices we are able to obtain an average increase in the performances of ~ 35× on a single GPU and ~ 78× on multi GPU with the respect of CPU execution.

Abstract
Hyperglycemia and hyperinsulinemia may play a role in breast carcinogenesis and prediabetes and diabetes have been associated with increased breast cancer (BC) risk. However, whether BC molecular subtypes may modify these associations is less clear. We therefore investigated these associations in all cases and by BC molecular subtypes among women living in Southern Italy. Cases were 557 patients with non-metastatic incident BC and controls were 592 outpatients enrolled during the same period as cases and in the same hospital for skin-related non-malignant conditions. Adjusted multivariate logistic regression models were built to assess the risks of developing BC in the presence of prediabetes or diabetes. The analyses were repeated by strata of BC molecular subtypes: Luminal A, Luminal B, HER2+, and Triple Negative (TN). Prediabetes and diabetes were significantly associated with higher BC incidence after controlling for known risk factors (OR = 1.94, 95% CI 1.32-2.87 and OR = 2.46, 95% CI 1.38-4.37, respectively). Similar results were seen in Luminal A and B while in the TN subtype only prediabetes was associated with BC (OR = 2.43, 95% CI 1.11-5.32). Among HER2+ patients, only diabetes was significantly associated with BC risk (OR = 3.04, 95% CI 1.24-7.47). Furthermore, when postmenopausal HER2+ was split into hormone receptor positive versus negative, the association with diabetes remained significant only in the former (OR = 5.13, 95% CI 1.53-17.22). These results suggest that prediabetes and diabetes are strongly associated with BC incidence and that these metabolic conditions may be more relevant in the presence of breast cancer molecular subtypes with positive hormone receptors.

Abstract
Breast cancer (BC) is the most common malignant tumor in women, obesity is associated with increased BC incidence and mortality and high levels of circulating insulin may negatively impact on cancer incidence. In the present study, we investigated whether the strength of several anthropometric and metabolic parameters varies between BC molecular subtypes. Eligible cases were 991 non-metastatic BC patients recruited between January 2009 and December 2013. Anthropometric, clinical and immunohistochemical features were measured. Multivariate logistic regression models were built to assess HER2 positive BC risk, comparing (a) triple positive (TP) with luminal A, luminal B and triple negative (TN) and (b) HER2-enriched group with luminal A, luminal B and TN. We stratified patients in pre- and post-menopause: significant differences emerged for luminal A in relation to age: they were more likely to be older compared to other groups. Among postmenopausal patients, the adjusted multivariate analysis showed that high BMI and high waist circumference were inversely correlated to TP subtype when compared to luminal B (OR=0.48 and OR=0.49, respectively). Conversely, HOMA-IR was a risk factor for TP when compared to luminal A and TN (OR=2.47 and OR=3.15, respectively). Our findings suggest a potential role of higher abdominal fat in the development of specific BC molecular subtypes in postmenopausal women. Moreover, they support a potential role of insulin resistance in the development of HER2 positive BC, although this role appears to be stronger when hormone receptors are co-expressed, suggesting a difference in the etiology of these two BC subtypes.

Abstract
AIM Basal cell carcinoma (BCC) is the most common skin malignant neoplasm in humans. Its localization and its clinical-pathological aspects are fundamental for the treatment and the outcome of these tumors. We wanted to verify if different clinical-pathological subtypes of BCC may be present with different frequencies on single skin areas. METHODS Three hundred six patients affected by BCC seen in Sant'Andrea Hospital, U.O.C. Dermatology, NESMOS Department, Faculty of Medicine, University of Rome "Sapienza", from January 2008 to December 2010, were retrospectively included in this study. Findings from all patients were tabulated and analyzed to characterize the clinical-pathological aspects of BCC according to their anatomic localization. We considered the following clinical subtypes of BCC, nodular, superficial, sclerodermiform, pearly and ulcerative. RESULTS One hundred ninety-seven out of 306 patients (64.4%) were localized on the head, 6 (1.9%) on the neck, 73 patients (23.9%) on the trunk, 2 (0.6%) on the perineum, 4 (1.3%) on upper limbs and 24 (7.9%) on legs. On the head BCC were mostly nodular (44.7%). On the trunk they were mostly superficial (34.3%). BCC on legs were ulcerative in all the 24 patients. CONCLUSION Our data confirm that BCC may have different clinical-pathological aspects on single skin areas. Interestingly in our casistic BCC on the legs were present in an uncommon high percentage. They presented as ulcerative lesions and this fact leads to conclude that in every patient presenting a chronic ulcer on the leg with difficulty to be cured a biopsy is mandatory to put in evidence the possible presence of BCC and consequently to perform the correct surgical treatment to obtain a complete response for the patient.

Abstract
We report a case of Lichen Sclerosus in a 73-year-old man who had been treated for epilepsy with carbamazepine. Lichen sclerosus et atrophicus (LSA), also called lichen sclerosus (LS), is a chronic inflammatory cutaneous condition characterized by white plaques with epidermal atrophy and scarring. To date no cases of LSA has been linked to carbamazepine, although in a few cases lichenoid eruptions but without sclero-atrophy have been described after exposure to this drug. Therefore, to our knowledge, this is the first report of a Lichen sclerosus et atrophicus induced by carbamazepine.

Abstract
We report a case of severe tinea capitis, treated successfully with griseofulvin. In our opinion, the treatment of this severe dermatophytosis with griseofulvin is safe and effective. Other treatments, such as itraconazole pulsed therapy, failed, despite an initial improvement, leading to an aggressive recurrence of the lesion. We chose griseofulvin for its well-known large spectrum activity, also against uncommon species, like Microsporum Gypseum, which are responsible for the most severe cases.

Abstract
Malignant gliomas have low survival expectations regardless of current treatments. Nonsteroidal anti-inflammatory drugs (NSAIDs) prevent cell transformation and slow cancer cell growth by mechanisms independent of cyclooxygenase (COX) inhibition. Certain NSAIDs trigger the endoplasmic reticulum stress response (ERSR), as revealed by upregulation of molecular chaperones such as GRP78 and C/EBP homologous protein (CHOP). Although celecoxib (CELE) inhibits the sarcoendoplasmic reticulum Ca(2+) ATPase (SERCA), an effect known to induce ERSR, sulindac sulfide (SS) has not been reported to affect SERCA. Here, we investigated these two drugs for their effects on Ca(2+) homeostasis, ERSR, and glioma cell survival. Our findings indicate that SS is a reversible inhibitor of SERCA and that both SS and CELE bind SERCA at its cyclopiazonic acid binding site. Furthermore, CELE releases additional Ca(2+) from the mitochondria. In glioma cells, both NSAIDS upregulate GRP78 and activate ER-associated caspase-4 and caspase-3. Although only CELE upregulates the expression of CHOP, it appears that CHOP induction could be associated with mitochondrial poisoning. In addition, CHOP induction appears to be uncorrelated with the gliotoxicity of these NSAIDS in our experiments. Our data suggest that activation of ERSR is primarily responsible for the gliotoxic effect of these NSAIDS. Because SS has good brain bioavailability, has lower COX-2 inhibition, and has no mitochondrial effects, it represents a more appealing molecular candidate than CELE to achieve gliotoxicity via activation of ERSR.

Abstract
Perinatal asphyxia (PA) is a medical condition associated with a high short-term morbimortality and different long-term neurological diseases. In previous work we have observed at 6 months post-synaptic densities (PSDs) alterations compatible with neurodegeneration highly correlated with the increment in the ubiquitination. Although alterations in the synaptic organization and function have been related with neuronal death after hypoxia, little is known about the synaptic changes in young animals exposed to PA. The main aim of this work is to study the PSDs changes in striatum of 30-day-old rats subjected to PA. Using two-dimensional electron microscopic analyses of synapses staining with ethanolic phosphotungstic acid we observed an increment of PSD thickness in severe hypoxic rats. These data are consistent with the western blot analysis that showed an increment in ubiquitination levels in the synapses of severe hypoxic rat. We did observe any alterations neither in synaptic structure nor in ubiquitinization in mild asphyctic rats. These data suggest that hypoxia might cause early misfolding and aggregation of synaptic proteins in severe anoxic animas that could induce long-term neurodegeneration.

Abstract
We report the case of a sciatic nerve section in a patient operated for a multi-acetabular loosening. Clinical symptoms were a progressive sensitive and motor deficit in the sciatic nerve territory. At the last loosening, the Burch-Schneider metal frame, which builds on the ischium, tipped on its axis causing the large section of the sciatic nerve. A literature review will discuss this rare case and give some recommendations.

Abstract
BACKGROUND AND PURPOSE Hunter syndrome (MPS type II) is a rare X-linked recessive disease caused by lysosomal enzyme iduronate-2-sulfatase deficiency, characterized by frequent and variable brain and skull involvement. Our objective was determine the frequency of closed cephaloceles in a large cohort of subjects affected with Hunter syndrome and to investigate possible correlations with clinical and neuroradiologic findings. MATERIALS AND METHODS Brain MR imaging of 33 patients (32 males and 1 female, age range 2.5-30.8 years, mean age 10.4 years) affected with Hunter syndrome were retrospectively evaluated. Eleven (age range 3.6-30.8 years; mean age 15.1) presented with an "attenuated" phenotype, while 22 (age range 2.5-19.1 years; mean age 8.2) had a "severe" phenotype. RESULTS A closed cephalocele was detected in 9/33 patients (27%) at the level of anterior and middle fossa in 6 and 3 cases, respectively; 6/9 subjects were affected with the attenuated phenotype and 1/9 suffered from epilepsy. Closed cephaloceles did not show a significant association with other brain and spine MR imaging features of Hunter disease, such as enlargement of perivascular spaces, cisterna magna, pituitary sella, ventricles and subarachnoid spaces, craniosynostosis, dens hypoplasia, white matter abnormalities, spinal stenosis due to periodontoid cap, platyspondylia, or intervertebral disk anomalies. CONCLUSIONS Closed cephaloceles are frequent in Hunter syndrome and should be considered a neuroradiologic feature of this disease.

Abstract
Management of lower limb fractures in children involves many approaches, spanning from conservative treatment to open reduction and internal fixation. A number of intermediate treatments have also been shown to be effective, notably skeletal traction. However, each of these techniques has its own advantages and disadvantages in terms of complications. In this report, we describe two new cases of chronic osteomyelitis that manifested (many years) after childhood skeletal traction. After analysing these two cases, we proposed measures that can be implemented to avoid such complications, along with a simple, appropriate, reproducible treatment approach.

Abstract
It has been previously demonstrated that "Warm temperature Acclimation-related 65 kD Protein" (WAP65) is involved in temperature acclimation, response to intoxication and infection, as well as in development. The expression of wap65-1 was investigated in the liver of European sea bass (Dicentrarchus labrax) during exposure to the increased temperature (from 12 deg C to 30 deg C) and during intoxication with four heavy metals: lead, cadmium, copper and zinc. Post temperature increase wap65 expression was highest after one hour at 30 deg C. After 1 to 4 weeks at 30 deg C wap65 transcript levels did not differ from the 12 deg C control group, similar to observations regarding the heat shock protein, hsp70. Upregulation of wap65 was detected after treatment (intoxication) with cadmium (0.5 μg/l). In contrast, a slight, but significant down regulation of wap65 was seen after copper (5 μg/l) intoxication. These data indicate that functional analyses of WAP65 are needed to understand the differential regulation of this gene by metals. The role of WAP65 may be similar to that of HSP70, which has generalized functions in responding to certain stressors and maintaining normal cell physiology.

Abstract
BACKGROUND Accumulation of glycosaminoglycans is known to cause significant problems in the anesthetic management of children with mucopolysaccharidoses (MPS). Clinical and standard radiological evaluation may convey insufficient information about the upper airway and trachea in children with MPS. Multidetector computed tomography (MDCT) images have been used to define the central airway and previous studies have recommended this tool to assess the airway of children who are considered at risk of difficult intubation. However, MDCT has not been recommended in MPS children. The aim of this clinical scenario study was to verify whether information from MDCT reconstruction of the airway is useful in airway management planning of children with MPS. METHODS In a two phase questionnaire-based study, 26 pediatric anesthesiologists were asked to produce airway management plans for 5 children with MPS. An initial plan for airway control was reported after assessment of standard preoperative anesthetic charts. A subsequent airway strategy was then described after reviewing tracheal MDCT images of each patient. RESULTS MDCT images provided additional clinically-relevant information in 87% (95% CI: 79-92%) of the evaluations. Reduction of tracheal size was the most common finding provided by the MDCT images. After reviewing the MDCT images, anesthesiologists changed their primary airway device selection in 21% of the evaluations (P=0.01). CONCLUSION Airway reconstruction using MDCT images from a previous CT scan may provide a useful assessment tool for preoperative airway evaluation and planning in MPS children.
