Abstract
Ozone detection is currently the subject of wide scientific and technological research, motivated by its harmful impact on human safety, environment and health. With the aim of searching for new highly sensitive materials for ozone detection, Ga-doped ZnS and ZnS-ZnO films were deposited by a spray pyrolysis technique. The obtained films were annealed at 400 °C for two hours. The ozone sensing properties were investigated by measuring the sensor resistance for several ozone concentrations ranging from 30 to 120 ppb. The sensor response reveals a dependence on the gallium concentration. The best response was obtained with 4% doping gallium. The sensitivity is 4.5 ppb-1 at 260 °C and the response to 30 ppb ozone is 150. Moreover, the sensor shows high performance such as good selectivity and fast rapidity.

Abstract
OBJECTIVE To assess the learning curve and evaluate the impact of surgical experience related to the outcomes of flexible ureteroscopy (fURS) for upper urinary tract stones. METHOD We evaluated retrospectively lithiasis fURS performed in our institution between January 2004 and December 2020. Patients were divided into two groups by the number of procedures performed by surgeon. Group 1 (G1) included the first 50 procedures, and group 2 (G2) the next cases. These groups were matched on baseline characteristics by a propensity score. Stones free rate (SFR) and complication rate (CR) were compared. Learning curves were realized using logistic curve with 95% confidence interval. RESULTS After criteria exclusion and propensity score matching, 1548 procedures were analyzed (1:1, G1 and G2, n=774 procedures). A total of 29 surgeons were evaluated. The overall SFR was 68.4% without statistical difference between the two groups (G1=67.9% vs. G2=68.8%, P=0.72). The surgeon's experience was not associated with SFR (OR=1.15, 95% CI: 0.90-1.47), except in subgroup stones>2cm (OR=2.89, 95% CI: 1.29-6.46). The overall CR was 12.5%, mainly Clavien-Dindo grade I-II complications (96.2%). Surgical experience was not associated with CR (OR=1.06, 95% CI: 0.77-1.45). The overall logistic curves for probability of stone clearance and complication tended to be a flat slope. CONCLUSION Impact of surgical experience on fURS for UUTS was not associated with SFR and CR. However, for stones larger than 2cm, surgeon's experience tended to be associated with SFR, but without impact on overall complications. LEVEL OF EVIDENCE: 3

Abstract
Three-dimensional (3D) bioprinting is an emerging technology, which turned out to be an optimal tool for tissue engineering approaches. To date, different printing systems have been developed. Among them, the extrusion-based approach demonstrated to be the most suitable for skeletal muscle tissue engineering, due to its ability to produce and deposit printing fibers in a parallel pattern that well mimic the native skeletal muscle tissue architecture. In tissue bioengineering, a key role is played by biomaterials, which must possess the key requisite of 'printability'. Nevertheless, this feature is not often well correlated with cell requirements, such as motives for cellular adhesion and/or absorbability. To overcome this hurdle, several efforts have been made to obtain an effective bioink by combining two different biomaterials in order to reach a good printability besides a suitable biological activity. However, despite being efficient, this strategy reveals several outcomes limitations. We report here the development and characterization of a novel extrusion-based 3D bioprinting system, and its application for correction of volumetric muscle loss (VML) injury in a mouse model. The developed bioprinting system is based on the use of PEG-Fibrinogen, a unique biomaterial with excellent biocompatibility, well-suited for skeletal muscle tissue engineering. With this approach, we obtained highly organized 3D constructs, in which murine muscle progenitors were able to differentiate into muscle fibers arranged in aligned bundles and capable of spontaneously contracting when culturedin vitro. Furthermore, to evaluate the potential of the developed system in future regenerative medicine applications, bioprinted constructs laden with either murine or human muscle progenitors were transplanted to regenerate theTibialis Anteriormuscle of a VML murine model, one month after grafting.

Abstract
OBJECTIVE Several studies have reported blood transfusion were associated with a decrease of survival after oncological surgery. For kidney cancer, the effect of blood transfusion is still debated. The objective of this study was to determine the effect of blood transfusion after oncological nephrectomy on overall, specific and recurrence-free survival in a retrospective cohort of localized or locally advanced kidney cancer. MATERIAL AND METHODS We performed a monocentric retrospective analysis of all patients managed by surgery for localized or locally advanced renal cancer between January 2000 and December 2016. We compared overall and specific survival and recurrence-free survival between two groups: patients transfused and not transfused. Demographic, surgical and tumor characteristics were compared. Survival analyses were performed using univariate Cox regression and multivariate Cox proportional regression test. RESULTS We included 382 patients in this study: 320 (83.8%) were not transfused and 62 (16.2%) were transfused. Transfused patients were significantly older (P=0.001) and had a lower pre-operative hemoglobin level (P=0.008). Operative and oncological characteristics were also different between both groups. In univariate analysis, we showed that blood transfusion was associated with lower overall survival (P<0.001), specific survival (P<0.001), and recurrence-free survival (P<0.001). In multivariate analysis, we found that blood transfusion was not associated with overall survival, or specific survival, but it was associated with lower recurrence-free survival (HR: 1.967, CI95% [1.024-3.780], P=0.042). CONCLUSIONS Perioperative blood transfusion is an independent risk factor that increases tumor recurrence among patients treated with nephrectomy for renal cancer.

Abstract
OBJECTIVE In a prospective study, SARS-CoV-2 IgG seroprevalence was assessed during the second pandemic wave (W2) in a cohort of Inflammatory Bowel Disease (IBD) patients using biologics. The secondary aim was to compare, in the same cohort, the frequency of seropositivity and of COVID-19 during the second vs. the first (W1) wave. PATIENTS AND METHODS From November 2020 to March 2021, SARS-CoV-2 IgG seropositivity and the prevalence of COVID-19 were assessed in a cohort of IBD patients using biologics already studied at W1. INCLUSION CRITERIA age ≥ 18 years; diagnosis of IBD; follow-up; written consent. EXCLUSION CRITERIA SARS-CoV-2 vaccination. Risk factors for infection, compatible symptoms, history of infection or COVID-19, nasopharyngeal swab test were recorded. Data were expressed as median [range]. The χ2 test, Student's t-test, logistic regression analysis was used. RESULTS IBD cohort at W1 and W2 included 85 patients: 45 CD (52.9%), 40 UC (47.1%). When comparing the same 85 patients at W2 vs. W1, a higher SARS-CoV-2 seroprevalence at W2 was at the limit of the statistical significance (9.4% vs. 2.3%; p=0.05). The prevalence of COVID-19 at W2 vs. W1 was 3.5% (3/85) vs. 0% (0/85) (p=0.08). Contacts with COVID-19 patients and symptoms compatible with COVID-19 were more frequent at W2 vs. W1 (18.8 % vs. 0%; p=0.0001; 34.1% vs. 15.3%; p=0.004). At W2, history of contacts and new onset diarrhea were more frequent in seropositive patients [4/8 (50%) vs. 12/77 (15.6%); p=0.01 and 4/8 (50%) vs. 2/77 (2.6%); p=0.0001]. At W2, the risk factors for seropositivity included cough, fever, new onset diarrhea, rhinitis, arthromyalgia, dysgeusia/anosmia at univariate (p<0.05), but not at multivariate analysis. History of contacts was the only risk factor for seropositivity at univariate (p=0.03), but not at multivariate analysis (p=0.1). CONCLUSIONS During W2, characterized by a high viral spread, IBD and biologics appeared not to increase the prevalence of SARS-CoV-2 infection or COVID-19 disease. New onset diarrhea mimicking IBD relapse may be observed in patients with SARS-CoV-2 infection.

Abstract
OBJECTIVE SARS-CoV-2 is a new Coronavirus identified as the cause of Coronavirus disease in 2019 (COVID-19). The epidemic spread in China and beyond its borders, involving 114 countries with more than 5 million dead. On March 11, the WHO declared the spread of SARS-CoV-2 to be a pandemic and encouraged nations to adopt harsh restrictive measures. Therefore, patients more and more often turn to dental offices only for emergencies. Healthcare professionals, including dentists, are at high infectious risk. In fact, the closeness to the oral cavity and nasopharynx and the use of drills or ultrasonic devices that cause aerosol release, make dental professions at high risk of bacterial and viral infections. The way patients are treated has changed. In fact, it should be mandatory to carry out a pre-treatment telephone triage and the use of mouthwashes to reduce bacterial load. In the current pandemic, it is necessary to adopt specific safety protocols that can protect dental operators as well as limit the spread of the virus. The purpose of this review is to present an overview on ways to reduce the risk of SARS-CoV-2 contagion in dentistry by focusing on the immediate situation as well as by looking towards the future. MATERIALS AND METHODS To reach the review purpose, we selected a series of studies using keywords "COVID-19" OR "SARS-CoV-2" in association with "dentistry" AND "safety protocols" AND "healthcare procedures" AND "individual protection dispositive" AND "air transmission" AND "droplet". We selected papers exclusively in English language, up to 1st January 2022. RESULTS During future phases of the pandemic, everywhere in the World, it is necessary to impose all dentistry team both a serological screening and the vaccination, as already established for all health staff in Italy. CONCLUSIONS For own safety, it is an important for the whole dentistry category constantly update the devices and the protocols adopted, as well as monitoring the real infectious threats, which may occur.

Abstract
OBJECTIVE Evidence supports a sex disparity in clinical outcomes of COVID-19 patients, with men exhibiting higher mortality rates compared to women. We aimed to test the correlation between serum levels of sex hormones [total testosterone, estradiol (E2), estradiol to testosterone (E2/T) ratio, progesterone), prolactin and 25-hydroxyvitamin D [25(OH)D] and markers of inflammation, coagulation and sepsis at admission in hospitalized men with COVID-19. PATIENTS AND METHODS We conducted an exploratory retrospective study including symptomatic men with confirmed SARS-CoV-2 infection who were consecutively admitted to our Institution between April 1 and May 31, 2020. RESULTS Patients were divided into survivors (n=20) and non-survivors (n=39). As compared to survivors, non-survivors showed significantly higher median neutrophil-to-lymphocyte ratio (NLR) values, D-dimer and procalcitonin (PCT) levels, along with significantly lower median 25(OH)D levels and total testosterone levels. Non-survivors exhibited significantly higher median values of E2/T ratio (a marker of aromatase activity). Spearman's correlation analysis revealed that total testosterone levels were significantly and inversely correlated with NLR, high-sensitivity C-reactive protein (hsCRP), interleukin-6, D-dimer and PCT. Conversely, E2/T ratio values were significantly and positively correlated with the aforementioned markers and with white blood cell (WBC) count. In a multivariate analysis performed by a logistic regression model after adjusting for major confounders (age, body mass index, hypertension and cardiovascular disease, diabetes mellitus and malignancy), total testosterone levels were significantly and inversely associated with risk of COVID-19-related in-hospital mortality. CONCLUSIONS Low total testosterone levels and elevated E2/T ratio values at admission are associated with hyperinflammatory state in hospitalized men with COVID-19. Low total testosterone levels at admission represent an independent risk factor for in-hospital mortality in such patients. Therefore, total testosterone and E2/T ratio may serve as prognostic markers of disease severity in this population.

Abstract
OBJECTIVE Treatments used in Inflammatory Bowel Disease (IBD) have been associated with enhanced risk of viral infections and viral reactivation, however, it remains unclear whether IBD patients have increased risk of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection. The aim of the study was to examine the prevalence of SARS-CoV-2 IgG positivity in IBD patients followed at our referral center. The role of treatments for IBD and risk factors for infection were also evaluated. PATIENTS AND METHODS In a prospective study, all IBD patients followed at our referral centre between May 27th and July 21st, 2020 and fulfilling the inclusion criteria were tested for SARS-CoV-2 IgG. Specific IgG antibodies were evaluated by a commercial ELISA kit and SARS-CoV-2 nasopharyngeal swab was performed in seropositive patients. RESULTS Two-hundred and eighteen patients, 128 Crohn's disease (CD) and 90 Ulcerative colitis (UC) [age 44, (19-77) years; ongoing biologics in 115 (52.7%)] were enrolled. No patient had major SARS-CoV-2-related symptoms. SARS-CoV-2 IgG were detected in 3 out of 218 (1.37%) patients with IBD (2 CD and 1 UC), all on biologics (2.6%). In all of the 3 seropositive patients, the nasopharyngeal swab was negative. There was no relationship between SARS-CoV-2 seroprevalence and the demographic/clinical characteristics of IBD patients. In contrast, history of recent travel was more frequent in the SARS-CoV-2 seropositive patients (2/3; 66.6%) than in SARS-CoV-2 seronegative patients [7/215 (3.25%); p<0.0001]. CONCLUSIONS The prevalence of SARS-CoV-2 IgG seropositivity in IBD patients appears to be comparable to the non-IBD population and not influenced by ongoing treatments. Risk factors for infection common to the general non-IBD population should be considered when managing patients with IBD.

Abstract
Introduction The deficiency of polyunsaturated fatty acids (PUFAs) and an alteration between the ratio of omega-6 and omega-3 PUFAs may contribute to the pathogenesis of depressive disorders. Objectives To investigate the levels of omega-3 and omega-6 in red cell membranes (mPUFAs) and plasma (pPUFAs) of patients with treatment-resistant (TRD) and non-treatment resistant depression (non-TRD). Methods TRD and non-TRD consisted of 75 patients enrolled at the Psychiatric and Clinic Psychology Unit of the University of Rome Tor Vergata, Rome, Italy, and met the DSM-IV criteria for major depressive disorder (MDD). A group of healthy controls (HC) matched for agender and age was enrolled. All blood samples were performed in conditions of an empty stomach between 07:00 am and 09:00 am. For each subject were obtained 5 ml of whole blood with the use of tubes for plasma with EDTA as an anticoagulant. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) for omega-3 and arachidonic acid (AA) for omega-6 were measured. Results Levels of pPUFAs did not differ between the three groups. The mPUFAs were altered in the MDD. TRD and non-TRD had lower EPA and AA values respect to the HC. DHA in red cell membranes was lower in TRD than non-TRD and HC. Conclusions Changes in levels of PUFAs in red cell membranes, but not in plasma, may be an important factor to evaluate the resistance to the pharmacological treatment.

Abstract
AbstractBrain-derived neurotrophic factor (BDNF) gene variants may potentially influence behaviour. In order to test this hypothesis, we investigated the relationship between BDNF Val66Met polymorphism and aggressive behaviour in a population of schizophrenic patients. Our results showed that increased number of BDNF Met alleles was associated with increased aggressive behaviour.

Abstract
The effects of white-light irradiation on ∼15 nm diameter ZnO nanoparticles are investigated by means of electron paramagnetic resonance, near liquid-nitrogen and liquid-helium temperatures. Under dark conditions, usual core- and surface-defects are detected, respectively, at g = 1.960 and g = 2.003. Under white-light illumination, the core-defect signal intensity is strongly increased, which is to be correlated to the light-induced conductivity's augmentation. Beside, a four-lines structure appears, with the same gravity center as that of the surface defects. Simulations and intensity power-dependence measurements show that this four-line-structure is very likely to arise from a localized high spin S = 2, induced by light irradiation, and subjected to a weak axial anisotropy. At 85 K, this high-spin state can last several hours after the light-irradiation removal, probably due to highly spin-forbidden recombination process. The possible excited resonant complexes at the origin of this signal are discussed. Other light-induced S = 1/2-like centers are detected as well, which depend on the nanoparticles growth conditions.

Abstract
Von Willebrand disease is a commonly inherited bleeding disorder caused by defects of von Willebrand factor (vWF). In the most common valve diseases, aortic valve stenosis (AVS) and mitral valve regurgitation (MVR), a bleeding tendency has been described in a number of patients. This has been associated to a high turbulence of blood flow through the compromised valve, promoting degradation of vWF with loss of high-molecular-weight multimers of vWF (HMWM), leading to an acquired von Willebrand syndrome (AvWS). We analysed three groups of patients, one affected by AVS, treated with transcatheter aortic valve implantation (TAVI), the second group of patients affected by MVR, treated with Mitraclip® mitral valve repair. The third group was represented by patients also affected by AVS, but not eligible for TAVI and treated with standard surgery. A fourth group of patients that underwent percutaneous coronary intervention (PCI) with stenting was used as a control. Our results demonstrated that the level of vWF measured as antigen concentration (vWF:Ag) increases in all cohorts of patients after treatment, while in control PCI patients, no modification of vWF:Ag has been registered. Western blot analysis showed only a quantitative loss of vWF in the pre-treatment time, but without significant HMWM modification. The monitoring of the vWF:Ag concentration, but not the quality of HMWM, can indicate the status of blood flow in the treated patients, thus introducing the possibility of using the vWF antigen detection in monitoring the status of replaced or repaired valves.

Abstract
AIM Evaluate the concordance between the renal lesions biopsy's histology and the final histology of the surgical specimen according to histological subtype, and search for predictive factors of non-concordance. MATERIAL We performed a monocentric retrospective study that included 156 patients suffering from a renal tumor that benefited a lesion biopsy before surgical treatment. Sensibility and specificity of the renal lesion's biopsy for histological diagnostic of the different renal tumors where calculated. RESULTS One hundred and fifty-eight renal tumor biopsies were realized between 2001 and 2016. One hundred and forty-three renal cell carcinoma were found on the surgical piece, 135 were diagnosed on prior biopsy. Global concordance rate was 88%. For the establishment of the nuclear Fuhrmann grade, the concordance rate (low vs. high grade) was 72.9%. The cohort was divided into 2 groups according to the existence (group 1, n=139) or the absence (group 2, n=19) of concordance. Group 1 and 2 differed by the predominance of men in group 1 (66% vs. 37%, P=0.013), distance between the sinus and the tumor above 4mm (65% vs. 42%, P=0.05). CONCLUSION In renal tumor care, renal biopsy is a reliable testing. However, some factors most likely linked to the tumor anatomy (intra-sinusal tumor) and their histological composition were involved in the lack of non-contribution to the diagnosis. LEVEL OF EVIDENCE 4.

Abstract
The pathogenic molecular mechanisms underlying the insurgence of nasal polyps has not been completely defined. In some patients, these lesions can have a recurrence after surgery removal, and the difference between recurrent and not recurrent patients is still unclear. To molecularly characterize and distinguish between these two classes, a cohort of patients affected by nasal polyposis was analysed. In all patients we analysed the p63 isoform expression using fresh tissues taken after surgery. Moreover, confocal immunofluorescence analysis of fixed sections was performed. The results show high ΔNp63 expression in samples from the nasal polyps of patients compared to the normal epithelia. Analysis of the expression level of the TAp63 isoform shows differential expression between the patients with recurrence compared to those not recurring. The data, considered as the ΔN/TAp63 ratio, really discriminate the two groups. In fact, even though ΔNp63 is expressed in non-recurrent patients, the resulting ratio ΔN/TAp63 is significantly lower in these patients. This clearly indicates that the status of TAp63 expression, represented by the ΔN/TAp63 ratio, could be considered a prognostic marker of low recurrence probability. In these samples we also investigated the expression of OTX2 transcription factor, known to be a selective activator of TAp63, detecting a significant correlation. Database analysis of HNSCC patients showed increased survival for the patients presenting OTX2 amplification and/or overexpression. These results, together with the fact that TAp63 can be selectively upregulated by HDAC inhibitors, open the possibility to consider local treatment of recurrent nasal polyps with these molecules.

Abstract
OBJECTIVE The aim of the study was to examine the safety and efficacy of dronedarone in patients with a history of atrial fibrillation and amiodarone-induced hyperthyroidism. PATIENTS AND METHODS We conducted a prospective study to evaluate the use of amiodarone and dronedarone in 124 patients with a history of paroxysmal atrial fibrillation who had no additional structural heart disease. All patients received amiodarone 200 mg qd. Out of 124 patients, 56 (45%) switched to dronedarone 400 mg bid due to amiodarone-induced hyperthyroidism and the remaining 68 patients (55%), with normal thyroid function, continued to receive amiodarone. The follow-up period was 12 months, and the patients were regularly monitored. RESULTS The primary outcome after 6 months dronedarone and amiodarone group was 56 and 68, including 38 (68%) and 54 (79.4%) (Odds ratio [OR] = 1.17, 95% confidence interval [95% CI] = 0.68-2.02) patients with sinus rhythm (SR) and 18 (32.14%) and 14 (28.6%) (odds ratio [OR] = 0.64, confidence interval [95% CI] = 0.29-1.40) patients with atrial fibrillation (AF). The secondary outcome after 12 months showed significant difference in thyroid function in the dronedarone group. Out of 46 patients, 24 (56.18%) patients reduced hyperthyroidism compared to the amiodarone group; out of 68, 6 (8.9%) patients were observed to have hyperthyroidism. At 12 months, there were 24 (43%) and 22 (62%) (odds ratio [OR] = 0.75, confidence interval [95% CI] = 0.38-1.49) patients with SR, and 32 (57%) and 26 (38%) (odds ratio [OR] = 0.67, confidence interval [95% CI] = 0.36-1.25) patients with AF. CONCLUSIONS In our study, dronedarone appears to be a good therapeutic option in the treatment of atrial fibrillation in patients with amiodarone-induced hyperthyroidism. However, long-term studies are needed to estimate the efficacy and toxicity of both drugs.

Abstract
OBJECTIVES To investigate the association between adherence to the Mediterranean Diet (Med-Diet), cardiometabolic disorders and polypharmacy. DESIGN Cross-sectional study. SETTING Geriatrics outpatient clinic, Policlinico Umberto I, Sapienza University of Rome. PARTICIPANTS 508 patients (219 male, 289 female) aged 50 to 89 who were evaluated for cardiovascular and metabolic disorders. METHODS AND MEASUREMENTS Patients underwent a comprehensive medical assessment including medical history and the use of medications. Adherence to Med-Diet was assessed using the validated Med-Diet 14-item questionnaire; for the analysis, patients were divided in high (≥8) and medium-low (<8) adherence. Polypharmacy was defined as taking ≥5 medications. RESULTS 476 patients completed the study. Mean age was 70.4 years; 58% female. Median Med-Diet score was 8 (interquartile range, 6-9). Patients with medium-low adherence had higher body mass index (p=0.029) and higher prevalence of arterial hypertension (p<0.001), previous coronary (p=0.002) and cerebrovascular events (p=0.011), diabetes, (p<0.001) and dyslipidemia (p=0.001) compared to those at high adherence. Med-Diet score decreased with the number of cardiometabolic disorders (p<0.001). The prevalence of polypharmacy was 39%. Consumption of olive oil (p=0.005), vegetables, (p<0.001), wine (p=0.017), legumes (p=0.028), fish (p=0.046) and nuts (p=0.045) were all inversely associated with the overall number of medications. In a multivariable regression model, medium-low adherence to Med-Diet was independently associated to polypharmacy (O.R.:1.859; 95% CI 1.142 to 3.025; p=0.013), after adjusting for possible confounding factors. CONCLUSION Med-Diet was inversely associated with cardiometabolic disorders and with polypharmacy, suggesting that improved Med-Diet adherence might potentially delay the onset of age-related health deterioration and reduce the need of multiple medications.

Abstract
OBJECTIVE To verify safety respect to weight loss, cardiometabolic diseases of short-term Very low-calorie ketogenic diets (VLCKDs, <800 kcal day-1). PATIENTS AND METHODS Randomized cross-over trial with placebo. The study had no. 2 dietary treatment (DT), conducted in two arms: (1) VLCKD1 in which 50% of protein intake is replaced with synthetic amino acids; (2) VLCKD2 with placebo. The VLCKDs (<800 kcal day-1) were different in term of protein content and quality each arm lasted three weeks (wks). Between the two arms a 3-wks washout period was performed to avoid additive effects on DT to follow. At the baseline, at start and end of each arm, all the subjects were evaluated for their health and nutritional status, by anthropometric analysis, body composition (Dual X-ray Absorptiometry (DXA), Bioimpedentiometry, biochemical evaluation, and Peroxisome Proliferator-Activated Receptor γ (PPAR) γ expression by transcriptomic analysis. RESULTS After VLCKD1 were reduced: Body Mass Index (BMI) (Δ%=-11.1%, p=0.00), Total Body Water (TBW) (p<0.05); Android Fat Percentage (AFP) (Δ%=-1.8%, p=0.02); Android Fat Mass (AFM) (Δ%=-12.7%, p=0.00); Gynoid Fat Mass (GFM) (Δ%=-6.3%, p=0.01); Intermuscular Adipose Tissue (IMAT) (Δ%= -11.1%, p=0.00); Homeostasis Model Assessment of Insulin Re-sistance (HOMA-IR) (Δ%=-62.1%, p=0.01). After VLCKD1 a significant increase of uricemia, cre-atinine and aspartate aminotransferase (AST) (respectively Δ%=35%, p=0.01; Δ%=5.9%, p=0.02; Δ%=25.5%, p=0.03). After VLCKD2 were reduced: BMI (Δ%=-11.2%, p=0.00); AFM (Δ%=-14.3%, p=0.00); GFM (Δ%=-6.3%, p=0.00); Appendicular Skeletal Muscle Mass Index (ASMMI) (Δ%=-17.5%, p=0.00); HOMA-IR (Δ%=-59,4%, p=0.02). After VLCKD2, uricemia (Δ%=63.1%, p=0.03), and Vitamin D levels (Δ%=25.7%, p=0.02) were increased. No significant changes of car-diovascular disease (CVD) indexes were observed after DTs. No significant changes of PPARγ lev-el in any DTs. CONCLUSIONS 21-days VLCKDs not impair nutritional state; not cause negative changes in global measurements of nutritional state including sarcopenia, bone mineral content, hepatic, renal and lipid profile.

Abstract
OBJECTIVE Very low-calorie diets (VLCDs, < 800 kcal day-1) and Ketogenic diet (KD) are generally used as part of integrated intervention, medical monitoring and a program of lifestyle modification, to improve a multitude of clinical states. The effect of three different very low calories KD (VLCKD), with (VLCKD1) or without (VLCKD2,3) synthetic amino acid replacement of the 50% protein intake, were analyzed after weight loss. PATIENTS AND METHODS The clinical study used a cross-over randomized double-blind placebo-controlled trial. Obese subjects, who were eligible for the study, were randomly (R) divided into three groups: one intervention group (IG) and two control groups (CG1 and CG2). We comprehensively analyzed body composition, serum metabolites, superoxide dismutase (SOD1), nuclear factor kappa-light-chain-enhancer of activated B cells (NfKB), Chemokine (C-C Motif) Ligand 2 (CCL2) gene expression. RESULTS After VLDKDs a significant decreased in BMI was observed. TBF (kg) significantly decrease after VLCKD1 and VLCKD3. After VLCKD2, a reduction of waist circumference (p = 0.02), FM L2-L5 (p < 0.05) was observed. After VLCKD1 reduction of IMAT (p = 0.00), LDL-C (p = 0.00) and HDL-C (p = 0.00) were observed. No significant changes of GH, ESR, and fibrinogen were highlighted. CRP (p = 0.02) reduced significantly after VLCKD3. Significant modulation of SOD1 expression (p = 0.009), CRP and decrease of glucose levels (p = 0.03) were obtained after VLCKD3. CONCLUSIONS This is the first study that analyzes comprehensively body composition, metabolic profile, and inflammation and oxidative stress genes expression after VLCKD. Our results show the efficacy of VLCKD with synthetic aminoacidic protein replacement, for the reduction of cardiovascular risk, without the development of sarcopenia and activation of inflammatory and oxidative processes.

Abstract
PURPOSE The aim of this study was to evaluate the efficacy and tolerance of renal stone fragmentation by flexible ureterorenoscopy (URS), compared to percutaneous nephrolithotomy (PCNL). MATERIAL AND METHODS Patients treated between 1998 and 2010 by URS and PCNL for intrarenal stone were reviewed. Patients' and stones' characteristics were analyzed. The preoperative parameters were reported as well as the procedure's efficiency and its complications. Success was defined by the absence of residual lithiasis visualized on renal imaging at 6 months of follow-up. RESULTS Among 531 patients included, there were 159 PCNL and 372 URS. The mean duration of hospitalization after PCNL was 8±4.6 days and 3±1.7 days after URS. The mean stones' size was higher in the PCNL group (19.9±7.5mm) than for the URS group (9.7±5.6mm; P<0.0001). The stone-free rate was significantly better in the PCNL group for stones measuring between 10 and 20mm (P<0.0001) and for stones of more than 20mm (P=0.017). Postoperative complications were significantly more frequent (27 %) and more severe (8.8 % vs Clavien III and IV) in the PCNL, than in the URS group, respectively (P=0.0001). CONCLUSION PCNL is a successful technique for renal stone fragmentation. However, URS seemed more tolerated despite a lower stone-free rate. LEVEL OF EVIDENCE 4.

Abstract
We found that in obese youth, plasma glucose above 155mg/dl (8.6mmol/l) at 60min of an OGTT, a predictor of type 2 diabetes (T2D) in adults, was present in 12% with normal glucose tolerance and 57% with impaired glucose tolerance. Performance of elevated 1-h glucose in predicting T2D in overweight youngsters should be tested.

Abstract
AIMS Evaluating the prevalence and the degree of steatosis in geriatric patients (65 to 85 years of age) with Metabolic Syndrome (defined by ATP III criteria); searching for metabolic factors which are predictive for the degree of steatosis; evaluating the efficacy of Ursodeoxycholic Acid (UDCA) for 6 months in the treatment of patients with NAFLD or NASH. MATERIALS AND METHODS We studied 87 geriatric patients with Metabolic Syndrome. Steatosis was diagnosed and graded by laboratory assessment and ultrasonography, method based on the determination of liver/kidney ratio through grey-scale intensity, which was calculated as an index of the severity of the steatosis: it could oscilates from 0 (none) to 3 (severe). We randomized the geriatric patients into two groups: Ursodeoxycholic Acid (UDCA)-treated group (n=43 pz) and diet-treated group (1200 Kcal/die for female, 1500 Kcal/die for male) (n=44 pz), for a period of 6 months. BMI, principal symptoms, liver function, blood lipids, ultrasonography liver were evaluated respectively before and after treatment. RESULTS The prevalence of steatosis was 100% (26 mild steatosis cases, 38 moderate cases and 23 severe cases) in our patients with Metabolic Syndrome. Of the 43 subjects assigned to receive 300-450 mg/d of UDCA and diet, the hepatic steatosis index decreased on the average, of the 75%. Serum AST, ALT and γ-GT decreased significantly at 3 months already (p<0.001). CONCLUSIONS UDCA improves liver enzymes and ultrasonography immaging in geriatric patients with NAFLD or NASH. Unexpectedly, UDCA has resulted in beneficial effects on glycemic control and insulin sensitivity.

Abstract
Congenital adrenal hyperplasia (CAH) is an autosomal recessive disorder mainly caused by defects in the 21-hydroxylase gene (CYP21A2), coding for the enzyme 21-hydroxylase (21-OH). About 95% of the mutations arise from gene conversion between CYP21A2 and the inactive pseudogene CYP21A1P: only 5% are novel CYP21A2 mutations, in which functional analysis of mutant enzymes has been helpful to correlate genotype-phenotype. In the present study, we describe 3 novel point mutations (p.L122P, p.Q481X, and p.E161X) in 3 Italian patients with CAH: the fourth mutation (p.M150R) was found in the carrier state. Molecular modeling suggests a major impact on 21-hydroxylase activity, and functional analysis after expression in COS-7 cells confirms reduced enzymatic activity of the mutant enzymes. Only the p.M150R mutation affected the activity to a minor extent, associated with NC CAH. CYP21A2 genotyping and functional characterization of each disease-causing mutation has relevance both for treatment and genetic counseling to the patients.

Abstract
OBJECTIVES To analyze the impact of the existence of Gleason grade 5 on the adverse pathology and biochemical recurrence-free survival of patients. PATIENTS Three hundred and seventy-two prostatectomies were performed between 1999 and 2011 in our institution for localised prostate adenocarcinoma. We examined the existence of grade 5 of the specimen to determine the reliability of prostate biopsies in the diagnosis of grade 5 and the association of grade 5 with other histoprognostic factors. Biochemical recurrence-free survival was analyzed according to the presence of grade 5 in the final specimen. RESULTS In total, all histological data and biochemical recurrence-free survival were available for 321 patients who were included in the study. Sixty-eight had Gleason grade 5 (majority or third minority pattern) on the specimen while 253 had not. Grade 5, rarely diagnosed on biopsy (sensitivity=26.47 %) was correlated independently with the extracapsular extension (OR=2.1; CI 95 [1.1-3.9]), the seminal vesicle invasion (OR=3.8; CI 95 [1.7-8.7]) and positive surgical margins (OR=2.0; CI 95 [1.1-3.6]). Overall survival was similar in both groups but the biochemical recurrence-free survival was statistically lower in the presence of grade 5 (HR=3.7; CI 95 [1.8-7.6]). Biochemical recurrence-free survival was not different than grade 5 is predominant or third minority pattern (HR=1.01; CI 95 [0.3-2.8]). On multivariate analysis, grade 5 was an independent risk factor for biochemical recurrence (P=0.005) as well as seminal vesicle invasion (P=0.047). CONCLUSION The existence of grade 5 in the surgical specimen whatever the percentage was a poor prognostic factor associated with increased tumor aggressiveness and reduced biochemical recurrence-free survival. LEVEL OF EVIDENCE 5.

Abstract
Acute myeloid leukemia (AML) is a highly lethal disease, especially in old patients. Chemoresistance and the absence of host immune responses against autochthonous malignancy play a major role in the poor prognosis of AML. The triazene compounds Dacarbazine and Temozolomide are monofunctional alkylators that donate methyl groups to many sites in DNA, including the O(6)-position of guanine producing O(6)-methylguanine (O(6)-MeG). If not repaired, O(6)-MeG frequently mispairs with thymine during DNA duplication. O(6)-MeG:T mismatches can be recognized by the mismatch repair (MMR) system which activates a cascade of molecular events leading to cell cycle arrest and cell death. If MMR is defective, cells continue to divide and GC → AT transition mutations occur. In preclinical models, such mutations can lead to the appearance of abnormal proteins containing non-self peptides ("chemical xenogenization" CX) that can be recognized by host cell-mediated immunity. Repair of O(6)-MeG is achieved by the DNA repair protein, O(6)-methylguanine-DNA methyltransferase (MGMT), which removes the methyl adduct in an autoinactivating stoichiometric reaction. High MGMT levels attenuate the pharmacodynamic effects of triazenes. In the last few years, triazenes, alone or with MGMT inhibitors, have been tested in AML. In view of their potential activity as CX inducers, triazenes could offer the additional advantage of host anti-leukemia immune responses. The present paper describes several studies of leukemia treatment with triazenes and a case of acute refractory leukemia with massive skin infiltration by malignant cells. Treatment with Temozolomide and Lomeguatrib, a potent MGMT inhibitor, produced a huge, although transient, blastolysis and complete disappearance of all skin lesions.

Abstract
miRNAs act as oncogenes or tumor suppressors in a wide variety of human cancers, including prostate cancer (PCa). We found a severe and consistent downregulation of miRNAs, miR-154, miR-299-5p, miR-376a, miR-376c, miR-377, miR-381, miR-487b, miR-485-3p, miR-495 and miR-654-3p, mapped to the 14q32.31 region in metastatic cell lines as compared with normal prostatic epithelial cells (PrEC). In specimens of human prostate (28 normals, 99 primary tumors and 13 metastases), lower miRNA levels correlated significantly with a higher incidence of metastatic events and higher prostate specific antigen (PSA) levels, with similar trends observed for lymph node invasion and the Gleason score. We transiently transfected 10 members of the 14q32.31 cluster in normal prostatic epithelial cell lines and characterized their affect on malignant cell behaviors, including proliferation, apoptosis, migration and invasion. Finally, we identified FZD4, a gene important for epithelial-to-mesenchymal transition in (PCa), as a target of miR-377.

Abstract
AIM OF THE STUDY To determine the epidemiology of urological emergencies in a university hospital and the interest of a dedicated urological emergency unit. PATIENTS AND METHODS In 2008, a dedicated urological emergency unit was individualized in our department of urology. We conducted a retrospective study including all patients consulting in this unit in 2009 with epidemiological, clinical and therapeutic data. RESULTS During 2009, 1257 patients consulted in this unit. Main diagnoses were acute urinary retention (303, 24.11%), renal colic (219, 17.42%), urinary infections (278, 22.11%), postoperative complications (141, 11.22%), symptomatic benign prostate hyperplasia (65, 5.17%), genitourinary cancers (61, 4.85%), trauma of urinary apparel (41, 3.26%), and spermatic cords torsion (10, 0.8%). In 99 cases (7.88%) diagnosis did not involved the urinary system. The treatment was surgical in 213 (17.7%) cases, technical procedure under local anesthesia in 368 (29.3%) and a medical treatment in 675 (53.7%) cases. Six hundred and sixty (52.5%) patients were managed ambulatory whereas 596 (47.5%) needed hospitalization. CONCLUSION The opening of a dedicated urological emergency unit lead to 1257 emergency consultations. Frequent etiologies were acute urinary retention, renal colic and urinary infection. The creation of this unit allowed to register and to valorize this emergency activity through the ATU emergency amount.

Abstract
PURPOSE Although obesity has been shown to paradoxically increase dialysis patient survival, its impact has not been clearly defined on renal transplantation. We assessed outcomes of obesity renal transplant patients by evaluating graft and patient survivals. PATIENTS AND METHODS A single-institution, retrospective study was performed on 202 renal transplant recipients from January 2004 to December 2008 excluding two combined kidney and liver transplantations. Recipients were classified based on body mass index (BMI) at the time of transplantation: obese (BMI ≥ 30 kg/m(2)) and nonobese recipients (BMI < 30 kg/m(2)). The comparative analysis included surgical complications, hospital stay, onset of delayed graft function (DGF), acute rejection episodes and graft patient survivals. RESULTS Twenty-one renal transplants were performed in obese recipients versus 179 in the control group. Obese patients were older (53.3 ± 11.2 versus 46.4 ± 14.4 years old; P = .035) and more often diabetic (29% ± 0.46 versus 60% ± 0.24, P = .001), but there were no differences among other combidities of high blood pressure, arteriopathy, thrombophilia, and smoking. Obesity did not appear to be a risk factor for urinary or vascular as well as parietal complications, but did tend to augment lymphatic complications (14.3% ± 0.36 versus 4.5% ± 0.21; P = .065). DGF occurred more frequently in obese patients (38% ± 0.50 versus 14% ± 0.34; P = .004) and hospital stays were therefore longer in this group (24.9 ± 23.53 days versus 15.6 ± 13.67 days; P = .008). Graft (hazard ratio [HR] 1.22; 95% confidence interval [CI] [0.25-6.0], P = .63) and patient survivals (HR:0,81; 95% CI [0.12- 5.3], P = .83) were comparable between the groups. CONCLUSION Obese patients seeking renal transplantation are usually older and more often diabetic compared with nonobese recipients. The higher rate of lymphatic complications and DGF lead to longer hospital stays among the group with BMI ≥ 30 kg/m(2). However, long-term results showed similar graft and patient survivals as nonobese patients. Consequently, there seemed to be no reason to avoid renal transplantation in obese recipients.

Abstract
Silencing of microRNAs (miRNAs) by promoter CpG island methylation may be an important mechanism in prostate carcinogenesis. To screen for epigenetically silenced miRNAs in prostate cancer (PCa), we treated prostate normal epithelial and carcinoma cells with 5-aza-2'-deoxycytidine (AZA) and subsequently examined expression changes of 650 miRNAs by megaplex stemloop reverse transcription-quantitative PCR. After applying a selection strategy, we analyzed the methylation status of CpG islands upstream to a subset of miRNAs by methylation-specific PCR. The CpG islands of miR-18b, miR-132, miR-34b/c, miR-148a, miR-450a and miR-542-3p showed methylation patterns congruent with their expression modulations in response to AZA. Methylation analysis of these CpG islands in a panel of 50 human prostate carcinoma specimens and 24 normal controls revealed miR-132 to be methylated in 42% of human cancer cases in a manner positively correlated to total Gleason score and tumor stage. Expression analysis of miR-132 in our tissue panel confirmed its downregulation in methylated tumors. Re-expression of miR-132 in PC3 cells induced cell detachment followed by cell death (anoikis). Two pro-survival proteins-heparin-binding epidermal growth factor and TALIN2-were confirmed as direct targets of miR-132. The results of this study point to miR-132 as a methylation-silenced miRNA with an antimetastatic role in PCa controlling cellular adhesion.
