- Abstract
Aim: Textbook outcome (TO) is a new surgical quality measure that combines structure, process and surgical outcomes into a single element. Our study aimed to determine the incidence of TO after simultaneous rectal and liver surgery and to use the achievement of TO as a tool to identify the best candidates for these complex procedures., Methods: In total, 256 patients who underwent simultaneous liver and rectal surgery for Stage IV rectal cancer between January 2004 and August 2019 at five tertiary centres were enrolled. TO was defined as a lack of complication, prolonged length of stay, readmission and death., Results: Mortality rate at 90 days and major morbidity rate were 2.3% and 15.6%, respectively. An overall TO was achieved in 59% of the patients, which is associated with significantly improved overall (median TO 86.3 months vs. no TO 37.4 months) and disease-free (median TO 70.6 months vs. no TO 24.9 months) survival. On multivariate analysis the presence of multi-comorbidities (OR 3.073) was associated with a reduced likelihood of achieving TO. Left lateral sectionectomy/limited resection was a protective factor (OR 0.416)., Conclusion: TO was achieved in six of 10 patients undergoing simultaneous resections for rectal cancer and liver metastases. Achieving a TO is strongly associated with improved long-term survival. The best candidates for these procedures were patients without multiple comorbidities and those treated with left lateral sectionectomy/limited resection., (© 2021 The Association of Coloproctology of Great Britain and Ireland.)

- Abstract
The OPERA experiment was designed to discover the v
τ appearance in a vμ beam, due to neutrino oscillations. The detector, located in the underground Gran Sasso Laboratory, consisted of a nuclear photographic emulsion/lead target with a mass of about 1.25 kt, complemented by electronic detectors. It was exposed from 2008 to 2012 to the CNGS beam: an almost pure vμ beam with a baseline of 730 km, collecting a total of 1.8·1020 protons on target. The OPERA Collaboration eventually assessed the discovery of vμ →vτ oscillations with a statistical significance of 6.1 σ by observing ten vτ CC interaction candidates. These events have been published on the Open Data Portal at CERN. This paper provides a detailed description of the vτ data sample to make it usable by the whole community., (© 2021.

- Abstract
We describe a multicenter experience with VNS implantation in pediatric patients with epileptic encephalopathy. Our goal was to assess VNS efficacy and identify potential predictors of favorable outcome. This was a retrospective study. Inclusion criteria were: ≤18 years at the time of VNS implantation and at least one year of follow-up. All patients were non-candidates for excisional procedures. Favorable clinical outcome and effective VNS therapy were defined as seizure reduction >50%. Outcome data were reviewed at one, two, three and five years after VNS implantation. Fisher's exact test, Kaplan-Meier and multiple logistic regression analysis were employed. Twenty-seven patients met inclusion criteria. Responder rate (seizure frequency reduction ≥ 50%) at one-year follow-up was 25.9%, and 15.3% at last follow-up visit. The only variable significantly predicting favorable outcome was time to VNS implantation, with the best outcome achieved when VNS implantation was performed within five years of seizure onset (overall response rate of 83.3% at one year of follow-up and 100% at five years). In total, 63% of patients evidenced improved QOL at last follow-up visit. Only one patient exited the study due to an adverse event at two years from implantation. Early VNS implantation within five years of seizure onset was the only predictor of favorable clinical outcome in pediatric patients with epileptic encephalopathy. Improved QOL and a very low incidence of adverse events were observed.

- Abstract
Objectives: A growing amount of evidence suggests that the rifampicin dosing currently recommended for tuberculosis treatment could be associated with inadequate exposure and unfavourable outcomes. We aimed to compare clinical and microbiological efficacy and safety outcomes of standard and higher rifampicin dosing., Methods: Data sources were MEDLINE, Google Scholar and the Cochrane Library. This was a systematic review and meta-analysis that included experimental or observational studies comparing 8-week sputum culture conversion, treatment failure, or safety outcomes in naïve patients with pulmonary tuberculosis treated with standard (10 mg/kg) or higher doses of rifampicin., Results: Of a total of 9683 citations screened, eight randomized controlled trials were included, accounting for 1897 subjects; the risk of bias was low in three studies, high in two and intermediate in three. At week 8 a higher proportion of patients in the high-dose group obtained a sputum culture conversion than those in the standard dose group (83.7% versus 80.6%, RR 1.06; 95%CI 1.01-1.12, p 0.028); this result was confirmed in the sub-analysis including patients treated with a rifampicin dose of ≥20 mg/kg, but not in those treated with 11-19 mg/kg. Events of treatment failure at end of treatment showed no significant difference between the two groups (RR 0.84; 95%CI 0.59-1.21, p 0.362). In the analysis evaluating safety outcome, the difference in the occurrence of a grade 3 or 4 liver toxicity or adverse drug reactions leading to discontinuation was not significant at the statistical analysis among the groups (7.2% versus 5.4%, RR 1.19; 95%CI 0.81-1.73, p 0.370, and 1.5% versus 0.6%, RR 2.31; 95%CI 0.65-8.21, p 0.195, respectively). No statistical heterogeneity among studies was observed for each outcome., Conclusions: High doses of rifampicin were associated with an increased rate of sputum culture conversion at 8 weeks of treatment, particularly in patients receiving ≥20 mg/kg., (Copyright © 2021 European Society of Clinical Microbiology and Infectious Diseases.

- Abstract
Prostate cancer, a leading cause of cancer-related deaths worldwide, principally occurs in over 50-year-old men. Nowadays there is urgency to discover biomarkers alternative to prostate-specific antigen, as it cannot discriminate patients with benign prostatic hyperplasia from clinically significant forms of prostatic cancer. In the present paper, 32 benign prostatic hyperplasia and 41 prostatic cancer urine samples were collected and analyzed. Polar and positively charged metabolites were therein investigated using an analytical platform comprising an up to 40-fold analyte enrichment step by graphitized carbon black solid-phase extraction, HILIC separation, and untargeted high-resolution mass spectrometry analysis. These classes of compounds are often neglected in common metabolomics experiments even though previous studies reported their significance in cancer biomarker discovery. The complex metabolomics big datasets, generated by the UHPLC-HRMS, were analyzed with the ROIMCR procedure, based on the selection of the MS regions of interest data and their analysis by the Multivariate Curve-Resolution Alternating Least Squares chemometrics method. This approach allowed the resolution and tentative identification of the metabolites differentially expressed by the two data sets. Among these, amino acids and carnitine derivatives were tentatively identified highlighting the importance of the proposed methodology for cancer biomarker research., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests., (Copyright © 2021 Elsevier B.V.

- Abstract
Objective: We describe a multicenter experience with vagus nerve stimulator implantation in pediatric patients with drug-resistant epilepsy. Our goal was to assess vagus nerve stimulation efficacy and identify potential predictors of favorable outcome., Methods: This is a retrospective study. Inclusion criteria: ≤18 years at time of vagus nerve stimulator implantation, at least 1 year of follow-up. All patients were previously found to be unsuitable for an excisional procedure. Favorable clinical outcome and effective vagus nerve stimulation therapy were defined as seizure reduction >50%. Outcome data were reviewed at 1, 2, 3, and 5 years after vagus nerve stimulator implantation. Fisher exact test and multiple logistic regression analysis were employed., Results: Eighty-nine patients met inclusion criteria. Responder rate (seizure frequency reduction >50%) at 1-year follow-up was 25.8% (4.5% seizure-free). At last follow-up, 31.5% had a favorable outcome and 5.2% were seizure free. The only factor significantly predicting favorable outcome was time to vagus nerve stimulator implantation, with the best outcome achieved when vagus nerve stimulator implantation was performed within 3 years of seizure onset. Implantation between 3 and 5 years after epilepsy onset correlated with better long-term seizure freedom (13.3% at T5). Overall, 65.2% of patients evidenced improved quality of life at last follow-up. However, 12.4% had adverse events, but most were mild and disappeared after 3-4 months., Conclusions: Early vagus nerve stimulator implantation within 5 years of seizure onset was the only predictor of favorable clinical outcome in pediatric patients. Improved quality of life and a low incidence of significant adverse events were observed.

- Abstract
Background and Aim: The aim of the present study was to assess the diagnostic performance of an LFA compared with an ELISA test in a cohort of HWs operating in a COVID-19 unit of a teaching hospital in southern Italy., Methods: We performed an observational, prospective, interventional study including 65 COVID-19 unit personnel. On a total of 196 serum samples (at least 2 serum samples for each HW), LFA and ELISA tests for SARS-COV-2 IgG and IgM were performed. Also, 32 serum samples of SARS-CoV-2 RNA positive patients at least 21 days before sampling, and 30 serum samples of patients obtained up to November 2019, before COVID-19 outbreak in China, were used as positive and negative controls, respectively., Findings: Of the 65 HWs enrolled, 6 were positive in LFA; overall, of the 196 serum samples, 20 were positive in LFA. All ELISA tests performed on serum samples collected from HWs were negative. The specificity of LFAs was 90.77% considering the 65 HWs and 89.80% considering all the 196 health workers serum samples analyzed. Considering the data on HWs, ELISA test for SARS-COV-2 antibodies showed a specificity of 100%, including all the 196 serum samples collected, and 100% including the 65 HWs. The ELISA and LFAs performed after 21 days last COVID-19 patient was discharged were all negative., Conclusion: LFAs compared to ELISA tests result in less specificity, considering COVID-19 negative personnel and patients. Thus, LFAs seem to be not adequate in the active surveillance of HWs., Competing Interests: All the authors of the manuscript declare that they have no conflict of interest in connection with this paper., (© 2020 Russo et al.)

- Abstract
We have designed a fully automated optical microscope running at high-speed and achieving a very high spatial resolution. In order to overcome the resolution limit of optical microscopes, it exploits the localized surface plasmon resonance phenomenon. The customized setup using a polarization analyzer, based on liquid crystals, produces no vibrations and it is capable of probing isolated nanoparticles. We tested its performance with an automated readout using a fine-grained nuclear emulsion sample exposed to 60 keV carbon ion beam and, for the first time, successfully reconstructed the directional information from ultra-short tracks produced by such low-energetic ions using a solid-state tracking detector.

- Abstract
Background : The outbreak of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and the related disease (COVID-19) has rapidly spread to a pandemic proportion, increasing the demands on health systems for the containment and management of COVID-19. Nowadays, one of the critical issues still to be pointed out regards COVID-19 treatment regimens and timing: which drug, in which phase, for how long? Methods : Our narrative review, developed using MEDLINE and EMBASE, summarizes the main evidences in favor or against the current proposed treatment regimens for COVID-19, with a particular focus on antiviral agents. Results: Although many agents have been proposed as possible treatment, to date, any of the potential drugs against SARS-CoV-2 has shown to be safe and effective for treating COVID-19. Despite the lack of definitive evidence, remdesivir remains the only antiviral with encouraging effects in hospitalized patients with COVID-19. Conclusions : In such a complex moment of global health emergency, it is hard to demand scientific evidence. Nevertheless, randomized clinical trials aiming to identify effective and safe drugs against SARS-CoV-2 infection are urgently needed in order to confirm or reject the currently available evidence.

- Abstract
Background: Enhanced Recovery After Surgery (ERAS) offers many benefits for patients with colorectal cancer. However, its application to patients with Crohn's disease (CD) is questioned., Aim: The aim of this propensity-matched study was to validate the results of ERAS protocol on CD patients., Methods: Patients undergoing ileocolic resection for primary or relapsed CD from 2007 to 2018 were retrospectively analyzed and propensity-matched into two equal groups (ERAS vs standard of care). Demographic characteristics, length of stay, bowel function, oral intake, and perioperative morbidity were analyzed., Results: Ninety four out of 299 patients were selected for analysis. No significant difference was observed for age, gender, American Society of Anesthesiologists score, body mass index, previous surgery and therapy, operative time and laparoscopy. The median length of stay in ERAS and non-ERAS groups was 6 and 8 days (p < 0.001). Median postoperative days of first bowel movement and solid oral intake were day 1 and day 2 p < 0,001, and day 2 and day 4.5 p < 0,001 in ERAS and non-ERAS group, respectively. No statistically differences in other postoperative outcomes were shown., Conclusions: ERAS implementation showed decreased length of stay, faster bowel function restoration and earlier solid oral intake in patients who underwent laparoscopic or open ileocolic resection for primary or relapsing CD., (Copyright © 2020 Editrice Gastroenterologica Italiana S.r.l.

- Abstract
Background: As a result of the increasing of life expectancy, the incidence of pathologies that can lead to operation for bowel obstruction is also increasing. Comorbidities and reduced physiological reserve can decrease elderly patients' ability to tolerate operations especially in an emergency context. We retrospectively evaluated the treatment and outcomes of a cohort of patients aged more than 85 years who underwent emergency surgery for intestinal occlusion., Methods: Two hundred seventy-eight patients who were admitted to our Institution and operated for acute bowel obstruction have been included in our study. We divided the study population in 2 groups (group A: patients aged>85 years old; group B patients aged ≤85 years). We evaluated the differences between the two groups in terms of intestinal occlusion aetiology, surgical procedures, morbidity and mortality rates., Results: Group A consisted of 57 patients, group B of 221; elderly patients trend in ASA score classification was significantly towards high risk for elderly group; statistical analysis did not show differences in terms of bowel obstruction etiology (except colon volvulus, more frequent in advanced age), type of procedure, duration of hospital stay, procedure-related complication rate. Perioperative mortality was significantly higher in elderly group, due to the mayor incidence of cardiovascular and respiratory fatal events directly related to pre-existing comorbidities., Conclusions: Despite the high surgical risk, early diagnosis and treatment of the obstructive disease can lead to achieve encouraging outcomes also in extremely advanced age; an aggressive evaluation of comorbidities and the cardiorespiratory risks reduction, when possible, could be useful in improve postoperative outcomes in terms of mortality.

- Abstract
Background: Acute calculous cholecystitis is a leading cause for hospital admission especially in developed countries. As older age population increases, medical research should consider the efficacy of all therapeutic options, including early surgical procedure in an emergency context, for the treatment of acute cholecystitis in elderly high-risk patients., Methods: From 01/01/2012 to 31/12/2016, 245 patients were admitted to our Institution with diagnosis of acute cholecystitis and managed with cholecystectomy within the same hospitalization. The study population was divided into 2 subgroups: group A (patients aged more than 80 years) and group B (patients within the limit of 80 years of age); the objective of the study was to evaluate and compare the surgical outcomes of the 2 groups in terms of conversion rate, mortality rate, overall morbidity and procedure-related complication rates., Results: Statistical analysis did not show significant differences between ultra octogenarian and younger patients in terms of conversion to open procedure, iatrogenic bile duct lesions, postoperative peritoneal bleeding, bile leakage and peritoneal collection; no differences in terms of hospital stay have been demonstrated. Mortality and overall morbidity rates, even if similar to what observed in Literature and within acceptable values, were significantly higher in elderly patients, due to the presence of severe comorbidities leading to potentially fatal postoperative events., Conclusions: Minimally invasive approach in an emergency setting for acute cholecystitis seems to be a feasible and adequate therapeutic approach for extremely aged high-risk patients.

- Abstract
Acinetobacter baumannii is an important nosocomial pathogen. Mechanisms that allow A. baumannii to cause human infection are still poorly understood. Iron is an essential nutrient for bacterial growth in vivo , and the multiplicity of iron uptake systems in A. baumannii suggests that iron acquisition contributes to the ability of A. baumannii to cause infection. In Gram-negative bacteria, active transport of ferrisiderophores and heme relies on the conserved TonB-ExbB-ExbD energy-transducing complex, while active uptake of ferrous iron is mediated by the Feo system. The A. baumannii genome invariably contains three tonB genes ( tonB1 , tonB2 , and tonB3 ), whose role in iron uptake is poorly understood. Here, we generated A. baumannii mutants with knockout mutations in the feo and/or tonB gene. We report that tonB3 is essential for A. baumannii growth under iron-limiting conditions, whereas tonB1 , tonB2 , and feoB appear to be dispensable for ferric iron uptake. tonB3 deletion resulted in reduced intracellular iron content despite siderophore overproduction, supporting a key role of TonB3 in iron uptake. In contrast to the case for tonB1 and tonB2 , the promoters of tonB3 and feo contain functional Fur boxes and are upregulated in iron-poor media. Both TonB3 and Feo systems are required for growth in complement-free human serum and contribute to resistance to the bactericidal activity of normal human serum, but only TonB3 appears to be essential for virulence in insect and mouse models of infection. Our findings highlight a central role of the TonB3 system for A. baumannii pathogenicity. Hence, TonB3 represents a promising target for novel antibacterial therapies and for the generation of attenuated vaccine strains., (Copyright © 2019 American Society for Microbiology.)

- Abstract
Limited attention has been given to the psychological impact of primary treatments in patients with prostate cancer. Aim of our analysis was to critically analyse the current evidence on the psychological impact of different primary treatments (surgery, radiotherapy and active surveillance), in patients with prostate cancer, using validated questionnaires. We searched in the MEDLINE and Cochrane library database from the literature of the past 15 years (primary fields: prostate neoplasm, AND radical prostatectomy or radiotherapy or active surveillance AND psychological distress or anxiety or depression; secondary fields: urinary, sexual, bowel modifications, non-randomised and randomised trials). Overall eighteen original and review articles were included and critically evaluated. Either radical prostatectomy or active surveillance and radiotherapy are well-tolerated in terms of definite anxiety and depression during the post-treatment follow-up. A mutual influence between functional and psychological modifications induced by treatments has been demonstrated. Urinary symptoms related to incontinence more than sexual and bowel dysfunction are able to induce psychological distress worsening. In conclusion, patients and their clinicians might wish to know how functional and psychological aspects may differently be influenced by treatment choice., (© 2018 Blackwell Verlag GmbH.)

- Abstract
The International League against Epilepsy (ILAE) proposed a diagnostic scheme for psychogenic non-epileptic seizure (PNES). The debate on ethical aspects of the diagnostic procedures is ongoing, the treatment is not standardized and management might differ according to age group. The objective was to reach an expert and stakeholder consensus on PNES management. A board comprising adult and child neurologists, neuropsychologists, psychiatrists, pharmacologists, experts in forensic medicine and bioethics as well as patients' representatives was formed. The board chose five main topics regarding PNES: diagnosis; ethical issues; psychiatric comorbidities; psychological treatment; and pharmacological treatment. After a systematic review of the literature, the board met in a consensus conference in Catanzaro (Italy). Further consultations using a model of Delphi panel were held. The global level of evidence for all topics was low. Even though most questions were formulated separately for children/adolescents and adults, no major age-related differences emerged. The board established that the approach to PNES diagnosis should comply with ILAE recommendations. Seizure induction was considered ethical, preferring the least invasive techniques. The board recommended looking carefully for mood disturbances, personality disorders and psychic trauma in persons with PNES and considering cognitive-behavioural therapy as a first-line psychological approach and pharmacological treatment to manage comorbid conditions, namely anxiety and depression. Psychogenic non-epileptic seizure management should be multidisciplinary. High-quality long-term studies are needed to standardize PNES management., (© 2018 EAN.)

- Abstract
The OPERA experiment was designed to study ν_{μ}→ν_{τ} oscillations in the appearance mode in the CERN to Gran Sasso Neutrino beam (CNGS). In this Letter, we report the final analysis of the full data sample collected between 2008 and 2012, corresponding to 17.97×10^{19} protons on target. Selection criteria looser than in previous analyses have produced ten ν_{τ} candidate events, thus reducing the statistical uncertainty in the measurement of the oscillation parameters and of ν_{τ} properties. A multivariate approach for event identification has been applied to the candidate events and the discovery of ν_{τ} appearance is confirmed with an improved significance level of 6.1σ. |Δm_{32}^{2}| has been measured, in appearance mode, with an accuracy of 20%. The measurement of the ν_{τ} charged-current cross section, for the first time with a negligible contamination from ν[over ¯]_{τ}, and the first direct evidence for the ν_{τ} lepton number are also reported.

- Abstract
Since sperm require high energy levels to perform their specialised function, it is vital that essential nutrients are available for spermatozoa when they develop, capacitate and acquire motility. However, they are vulnerable to a lack of energy and excess amounts of reactive oxygen species, which can impair sperm function, lead to immotility, acrosomal reaction impairment, DNA fragmentation and cell death. This monocentric, randomised, double-blind, placebo-controlled trial investigated the effect of 6 months of supplementation with l-carnitine, acetyl-l-carnitine and other micronutrients on sperm quality in 104 subjects with oligo- and/or astheno- and/or teratozoospermia with or without varicocele. In 94 patients who completed the study, sperm concentration was significantly increased in supplemented patients compared to the placebo (p = .0186). Total sperm count also increased significantly (p = .0117) in the supplemented group as compared to the placebo group. Both, progressive and total motility were higher in supplemented patients (p = .0088 and p = .0120, respectively). Although pregnancy rate was not an endpoint of the study, of the 12 pregnancies that occurred during the follow-up, 10 were reported in the supplementation group. In general, all these changes were more evident in varicocele patients. In conclusion, supplementation with metabolic and antioxidant compounds could be efficacious when included in strategies to improve fertility., (© 2018 The Authors.

- Abstract
Introduction: The aim of this study was to analyze the significance of an increase in total prostate-specific antigen (PSA) serum levels despite dutasteride treatment as a predictor of prostate cancer (PC) at biopsy. We focused our attention on the rate of the first PSA increase and on the influence of prostatic inflammation., Methods: From 2011 to 2016, 365 men with a previous negative prostate biopsy and persistent elevated PSA levels received dutasteride treatment. The population was followed for a range of 12-48 months., Results: One hundred twelve cases with a confirmed PSA increase >0.5 ng/ml over the nadir value during the follow-up were included in Group A and underwent a new prostate biopsy. In Group A, the PSA increase was associated with PC at the re-biopsy in 66% of cases. The percentage of PSA reduction after 6 months of treatment was not a significant indicator of the risk for PC. The distribution of inflammatory infiltrates significantly (p<00.01) varied from positive to negative prostate biopsies. The relative risk for PC at biopsy significantly increased according to PSA level during dutasteride., Conclusions: Treatment with dutasteride can help to analyze PSA kinetic. A persistent prostatic inflammation is a factor able to reduce the performance of PSA kinetic during dutasteride treatment.

- Abstract
There are two main approximate theories in the contact of rough solids: Greenwood-Williamson asperity theories (GW) and Persson theories. Neither of them has been fully assessed so far with respect to load-separation curves. Focusing on the most important case of low fractal dimension (D
f = 2.2) with extensive numerical studies we find that: (i) Persson's theory describes well the regime of intermediate pressures/contact area, but requires significant corrective factors: the latter depend also on upper wavevector cutoff of the roughness; hence, (ii) Persson's theory does not predict the correct functional dependence on magnification; (iii) asperity theories in the discrete version even neglecting interaction effects are more appropriate in the range of relatively large separations, also to take into consideration of the large scatter in actual realization of the surface.- Published

- Abstract
A well-designed learning curve is essential for the acquisition of laparoscopic skills: but, are there risk factors that can derail the surgical method? From a review of the current literature on the learning curve in laparoscopic surgery, we identified learning curve components in video laparoscopic cholecystectomy; we suggest a learning curve model that can be applied to assess the progress of general surgical residents as they learn and master the stages of video laparoscopic cholecystectomy regardless of type of patient. Electronic databases were interrogated to better define the terms "surgeon", "specialized surgeon", and "specialist surgeon"; we surveyed the literature on surgical residency programs outside Italy to identify learning curve components, influential factors, the importance of tutoring, and the role of reference centers in residency education in surgery. From the definition of acceptable error, self-efficacy, and error classification, we devised a learning curve model that may be applied to training surgical residents in video laparoscopic cholecystectomy. Based on the criteria culled from the literature, the three surgeon categories (general, specialized, and specialist) are distinguished by years of experience, case volume, and error rate; the patients were distinguished for years and characteristics. The training model was constructed as a series of key learning steps in video laparoscopic cholecystectomy. Potential errors were identified and the difficulty of each step was graded using operation-specific characteristics. On completion of each procedure, error checklist scores on procedure-specific performance are tallied to track the learning curve and obtain performance indices of measurement that chart the trainee's progress., Conclusions: The concept of the learning curve in general surgery is disputed. The use of learning steps may enable the resident surgical trainee to acquire video laparoscopic cholecystectomy skills proportional to the instructor's ability, the trainee's own skills, and the safety of the surgical environment. There were no patient characteristics that can derail the methods. With this training scheme, resident trainees may be provided the opportunity to develop their intrinsic capabilities without the loss of basic technical skills., Competing Interests: Conflict of interest statement: Authors state no conflict of interest.

- Abstract
Prostate is an immune-competent organ normally populated by inflammatory cells. Prostatic inflammation origin can be multi-factorial and there are some emerging evidences on its possible role as a factor involved in prostate cancer (PC) pathogenesis and progression. This review critically analyzes the role of inflammation as a prognostic factor for progression and aggressiveness of PC. We verified the last 10 years literature data on the association between inflammation and PC aggressiveness, or PC response to therapies. Several studies tried to correlate different inflammatory factors with the aggressiveness and metastatization of PC; all data sustain the role of inflammation in PC progression but they also produce confusion to identify a reliable clinical prognostic marker. Data on patients submitted to radical prostatectomy (RP) showed that cases with marked intraprostatic tissue inflammation are associated with higher rate of biochemical progression; systemic inflammation markers appear to have a significant prognostic value. Analyzing data on patients submitted to radiotherapy (RT) emerges a significant association between high neuthrophil to lymphocyte ratio (NLR) and decreased progression free survival and overall survival; also plateled to lymphocyte ratio (PLR) and C-reactive protein (CRP) have been proposed as significant prognostic factors for progression and overall survival. In patients submitted to androgen deprivation therapy (ADT), inflammation may drive castration resistant PC (CRPC) development by activation of STAT3 in PC cells. NLR has been proposed as independent predictor of overall survival in CRPC submitted to chemotherapy. Most of data are focused on markers related to systemic inflammation such as NLR and CRP, more than specifically to chronic prostatic inflammation. The suggestion is that these inflammatory parameters, also if not specific for prostatic inflammation and possibly influenced by several factors other than PC, can integrate with established prognostic factors.

- Abstract
Aim of the study is to highlight difficulties faced by an inexperienced surgeon in approaching endorectal-ultrasound, trying to define when learning curve can be considered complete. A prospective analysis was conducted on endorectal-ultrasound performed for subperitoneal rectal adenocarcinoma staging in the period from January 2008 to July 2013, reported by a single surgeon of Department of Oncology, Section of General Surgery, "San Luigi Gonzaga" Teaching Hospital, Orbassano (Turin, Italy); the surgeon had no previous experience in endorectal-ultrasound. Fourty-six endorectal-ultrasounds were divided into two groups: early group (composed by 23 endorectal-ultrasounds, made from January 2008 to May 2009) and late group (composed by 23 endorectal-ultrasound, carried out from June 2009 to July 2013). In our experience, the importance of a learning curve is evident for T staging, but no statystical significance is reached for results deal with N stage. We can conclude that ultrasound evaluation of anorectal and perirectal tissues is technically challenging and requires a long learning curve. Our learning curve can not be closed down, at least for N parameter., Competing Interests: Conflict of interest statement: Authors state no conflict of interest.

- Abstract
We present the use of a modified corporoplasty, based on geometrical principles, to determine the exact site for the incision in the tunica or plaque and the exact amount of albuginea for overlaying to correct with extreme precision the different types of congenital or acquired penile curvature due to Peyronie's disease. To describe our experience with a new surgical procedure for the enhancement of penile curvature avoiding any overcorrection or undercorrection. Between March 2004 and April 2013, a total of 74 patients underwent the geometrical modified corporoplasty. All patients had congenital curvature until 90° or acquired stable penile curvature 'less' than 60°, that made sexual intercourse very difficult or impossible, normal erectile function, absence of hourglass or hinge effect. Preoperative testing included a physical examination, 3 photographs (frontal, dorsal and lateral) of penis during erection, a 10 mcg PGE1-induced erection and Doppler ultrasound, administration of the International Index of Erectile Function (IIEF-15) questionnaire. A follow-up with postoperative evaluation at 12 weeks, 12 and 24 months, included the same preoperative testing. Satisfaction rates were better assessed with the use of validated questionnaire such as the International Erectile Dysfunction Inventory of the Treatment Satisfaction (EDITS). Statistical analysis with Student's t-test was performed using commercially available, personal computer software. A total of 25 patients had congenital penile curvature with a mean deviation of 46.8° (range 40-90), another 49 patients had Peyronie's disease with a mean deviation of 58.4 (range 45-60). No major complications were reported. Postoperative correction of the curvature was achieved in all patients (100%). Neither undercorrection nor overcorrection were recorded. No significant relapse (curvature>15°) occurred in our patients. Shortening of the penis was reported by 74% but did not influence the high overall satisfaction of 92% (patients completely satisfied with their sexual life). The erectile function was analyzed in both groups, Student's t-test showed a significant improvement in erectile function, preoperative average IIEF-15 scores were 17.43±4.67, whereas postoperatively it was 22.57±4.83 (P=0.001). This geometrical modified Nesbit corporoplasty is a valid therapy which allows penile straightening. The geometric principles make the technique reproducible in multicentre studies.

- Abstract
Our aim was to systematically evaluate the benefits of degarelix as antagonist versus agonists of gonadotropin-releasing hormones (GnRH) for the treatment of advanced prostate cancer (PC). This comparison was performed either in terms of biochemical or oncological or safety profiles. To this end we, carried out a systematic review and meta-analysis of the literature.We selected only studies directly and prospectively analyzing the two treatments in the same population (randomized phase III studies). We followed the Preferred Reporting Items for Systematic Reviews and meta-analyses process for reporting studies.After we eliminated studies according to the exclusion criteria, 9 publications were considered relevant to this review. These articles described 5 clinical trials that were eligible for inclusion. The follow-up duration in all trials did not exceed 364 days. This meta-analysis and review comprised a total of 1719 men, 1061 randomized to degarelix versus 658 to GnRH agonists treatment for advanced PC. Oncological results were evaluated only in 1 trial (CS21:408 cases) and they were not the primary endpoints of the study. Treatment emerging adverse events were reported in 61.4% and 58.8% of patients in the degarelix and GnRH agonists group, respectively (odds ratio, OR = 1.17; 95% confidence interval, 95% CI: 0.78-1.77, P > 0.1). Treatment related severe cardiovascular side effects were reported (trial CS21-30-35) in 1.6% and 3.6% of patients in the degarelix and GnRH agonists group, respectively (OR = 0.55, 95% CI: 0.26-1.14, P > 0.1).Our analysis evidences relevant limitations in particular for the comparative evaluation of the efficacy and the oncological results related to degarelix., Competing Interests: There are no conflicts of interest for all authors, related to this meta-analysis study.

Purpose: To evaluate clinical data from published trials on the use of intermittent androgen deprivation (IAD) therapy in patients with biochemical relapse after radical prostatectomy (RP)., Methods: We searched the Medline and Cochrane Library databases for literature published on IAD and biochemical progression after radical prostatectomy., Results: To date, we have oncological and functional data from phase 3 studies focused on metastatic and locally advanced stages that confirmed IAD as a valid option treatment. For the aim of this review, only Tunn study, was specifically focused on patients who relapsed after surgery but clear and mature results are still missed., Conclusions: The use of IAD in cases who relapse after RP is common in the clinical practice. Although specific recommendation on the use of IAD in this setting of patients are not available, we concluded that the real benefit of IAD in terms of long survival and quality of life is mainly for patients treated with surgery., (Copyright © 2016.

- Abstract
Erectile dysfunction, the most common male sexual disorder after premature ejaculation, with its important impact on man and partner's sexuality and quality of life is a persistent inability to obtain and maintain an erection sufficient to permit satisfactory sexual performance. Non-surgical treatments with controversial results are usually applyed before surgical treatment that has reached high levels of satisfaction. We describe a new surgical technique to implant three-pieces penile prosthesis in patients suffering from erectile dysfunction (ED) not responding to conventional medical therapy or reporting side effects with such a therapy. Implantation of an inflatable prosthesis, for treatment of ED, is a safe and efficacious approach with high satisfaction reported by patients and partners. Surgical technique should be minimally invasive and latest technology equipment should be implanted in order to decrease common complications and to obtain a better aesthetic result.

- Abstract
Erectile dysfunction (ED), the second most common male sexual disorder, has an important impact on man sexuality and quality of life affecting also female partner's sexual life. ED is usually related to cardiovascular disease or is an iatrogenic cause of pelvic surgery. Many non-surgical treatments have been developed with results that are controversial, while surgical treatment has reached high levels of satisfaction. The aim is to evaluate outcomes and complications related to prosthesis implant in patients suffering from ED not responding to conventional medical therapy or reporting side effects with such a therapy. One hundred eighty Caucasian male suffering from ED were selected. The patient population were divided into two groups: 84 patients with diabetes and metabolic syndrome (group A) and 96 patients with dysfunction following laparoscopic radical prostatectomy for prostate cancer (group B). All subjects underwent primary inflatable penile prosthesis implant with an infrapubic minimally invasive approach. During 12 months of follow-up, we reported 3 (1.67%) explants for infection, 1 (0.56%) urethral erosion, 1 (0.56%) prosthesis extrusion while no intraoperative complications were reported. Mean International Index of Erectile Function-5 (IIEF-5) was 8.2 ± 4.0 and after the surgery (12 months later) was 20.6 ± 2.7. The improvement after the implant is significant in both groups without a statistically significant difference between the two groups (P-value 0.65). Mean Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) score 1 year after the implant is 72.2 ± 20.7, and there was no statistically significant difference between groups A and B (P-value 0.55). Implantation of an inflatable prosthesis, for treatment of ED, is a safe and efficacious approach; and the patient and partner satisfaction is very high. Surgical technique should be minimally invasive and latest technology equipment should be implanted in order to decrease after surgery common complications (infection and mechanical failure).

- Abstract
Objectives: Curcumin, a naturally occurring compound derived from turmeric (Curcuma longa) has long been suggested to have strong therapeutic or preventive potential against human diseases because of its antioxidative, anticancerous, and anti-inflammatory effects. Curcumin is known to exert anti-inflammatory effects by interrupting NF-κB signaling at multiple levels. Many observations indicate that curcumin shows its valuable potential by inhibiting the activity of I-κB kinase. Transglutaminase 2 (TG2) expression is increased in inflammatory diseases. Data in the literature suggest that this enzyme activates the proinflammatory transcriptional factor NF-κB by inducing the polymerization of its inhibitory subunit I-κBα, which in turn results in the dissociation of NF-κB and its translocation to the nucleus, where it is capable of upregulating host inflammatory genes. Interestingly, NF-κB regulatory response elements are also present in the TG2 promoter, suggesting a possible role for this pathway in the mechanism responsible for chronic inflammation. On the basis of these literature data, our objective was to analyze the effects of curcumin on TG2 expression in human nervous cell lines., Methods: Human nervous cell lines were treated with curcumin alone or in association with retinoic acid in order to induce TG2 overexpression. TG2 levels were analyzed by Western blot and real-time PCR analyses., Results: Curcumin was able to downregulate the expression of TG2 in human nervous cell lines, which was also the case after treatment with retinoic acid., Conclusions: These results suggest a possible use of curcumin in reducing TG2 overexpression in human nervous cells., (© 2016 S.

- Abstract
Erectile dysfunction (ED) is inability to achieve and maintain an erection to permit satisfactory sexual activity. Homocysteine (Hcys) is a sulfur-containing amino acid synthesized from the essential amino acid methionine. Experimental models have elucidated the role of hyperhomocysteinemia (HHcys) as a strong and independent predictor for atherosclerosis progression and impaired cavernosal perfusion. The aim of this study is to investigate the serum levels of Hcys in our cohort of patients with ED, to compare these values with these of control population and to examine Hcys as a predictive marker for those patients who are beginning to complain mild-moderate ED. A total of 431 patients were enrolled in the study. The whole cohort was asked to complete the International Index of Erectile Function (IIEF) questionnaire. The study population was divided in 3 main groups: Group A: 145 patients with no ED serving as a control group; Group B: 145 patients with mild or mild-moderate ED; Group C: 141 patients with moderate or severe ED. Each participant underwent blood analysis. All patients underwent baseline and dynamic penile Doppler ultrasonography. We found in our cohort mean Hcys plasma concentrations significantly higher than the cut-off point in both groups B and C (18.6 ± 4.7 and 28.38 ± 7.8, respectively). Mean IIEF score was 27.9 ± 1.39, 19.5 ± 2.6, and 11.1 ± 2.5 for groups A, B, and C, respectively (P < 0.0001). In the penile Doppler ultrasonography studies, a high significant inverse correlation was detected between the mean values of the 10th minute's peak-systolic velocity (PSV) and Hcys levels for the groups B and C. This establishes a dose-dependent association between Hcys and ED. Furthermore, we showed that Hcys was an earlier predictor of ED than Doppler studies, as the Hcys increase was present in patients with mild ED even before abnormal Doppler values.

- Abstract
Objective: To compare the early vs late use of pelvic floor electrical stimulation (FES) plus biofeedback (BF) in terms of time to recovery and rate of continence after radical prostatectomy (RP)., Materials and Methods: Between April 2007 and April 2012, a total of 120 patients who underwent RP were prospectively included in the study. In group 1 (60 cases), we included patients who presented a urinary leakage weight ≥50 g for 24 hours, 14 days after catheter removal. In group 2 (60 cases), we included patients who continued to present a urinary leakage weight ≥50 g for 24 hours, 12 months after surgery. In both groups, patients were prospectively submitted to the same program of BF+FES., Results: Mean leakage weight became significantly lower (P <.002) in group 1 than in group 2 starting from visit 1 (2 weeks) through visit 7 (24 weeks). However, a significant difference (P <.05) between the 2 groups in terms of percentage of continent patients was achieved only at 2 weeks (group 1 = 20%; group 2 = 0%) and 4 weeks (group 1 = 66.7%; group 2 = 46.7%). The objective continence rate 6 months after the beginning of treatment was 96.7% in group 1 and 91.7% in group 2., Conclusion: In our experience, the treatment with BF and FES has a significant positive effect on the recovery of urinary continence independently to the time in which it is used (early vs delayed). This protocol might represent a noninvasive method for all patients undergoing RP, also in a 12-month interval from surgery., (Copyright © 2015 Elsevier Inc. All rights reserved.)

- Abstract
Background: Prostate cancer (PC) represents the most frequently diagnosed cancer in men. Exposure to infectious agents has been considered to induce prostatic inflammation and cancerous transformation. Controversial data exist concerning the role of the human polyomaviruses BK (BKV) and JC (JCV) in PC etiology. Therefore, a possible association between these polyomaviruses and PC was investigated., Materials and Methods: Urine, blood and fresh prostatic tissue specimens were collected from 26 patients with PC. The presence of BKV and JCV, the possible non-coding control region (NCCR) variations and the genotyping analysis of viral protein 1 (VP1) of both viruses were assessed., Results: Data showed a preferential viral re-activation in the urinary compartment and a statistically significant prevalence of JC viruria and of BKV in PC tissues. A BKV DDP-like NCCR sequence was isolated in two patients, whereas JCV NCCR was consistently of an archetypal structural organization. A prevalence of the European genotypes was observed for both viruses., Conclusion: Our data demonstrated the presence of JCV DNA in 14/24 (58.3%) cancerous prostatic tissue specimens, confirming the results obtained in a previous study, in which JCV has been defined as common inhabitant of the prostate, and opening the discussion about its potential role in PC., (Copyright© 2015, International Institute of Anticancer Research (Dr. John G.

- Abstract
Objective: To investigate if short-term treatment with dutasteride (8 weeks) before bipolar transurethral resection of the prostate (B-TURP) can reduce intraoperative bleeding, as dutasteride a dual 5α-reductase inhibitor (5-ARI) blocks the conversion of testosterone into its active form dihydrotestosterone (DHT), and reduces prostate volume and prostate-specific antigen (PSA) levels, while increasing urinary flow rate., Patients and Methods: In all, 259 patients were enrolled and randomised to two groups: Group A, receiving placebo and Group B, receiving dutasteride (0.5 mg daily for 8 weeks). Blood samples were taken before and after B-TURP for serum chemistry evaluation. In particular we evaluated blood parameters associated with blood loss [haemoglobin (Hb) and haematocrit (Ht)] and prostate vascularity [vascular endothelial growth factor (VEGF) immunoreactivity and microvessel density (MVD) using cluster of differentiation 34 (CD34) immunoreactivity]., Results: Total testosterone, DHT, PSA level and prostate volume were evaluated and with the exception of DHT and PSA level there was no statistically significant differences between the groups. When comparing changes in Hb and Ht between Group A and Group B before and after B-TURP, there was a statistically significant difference only in patients with large prostates of ≥50 mL (ΔHb 3.86 vs 2.05 g/dL and ΔHt 4.98 vs 2.64%, in Groups A and B, respectively). There was no significant difference in MVD and VEGF index in prostates of <50 mL, conversely in large prostates the difference become statistically significant., Conclusions: Dutasteride was able to reduce operative and perioperative bleeding only in patients with large prostates (≥50 mL) that underwent B-TURP. Our findings are confirmed by Hb and Ht values reported before and after the B-TURP and reductions in the molecular markers for VEGF and CD34 in the dutasteride-treated specimens., (© 2014 The Authors BJU International © 2014 BJU International Published by John Wiley & Sons Ltd.)

- Abstract
Background: Prostate cancer (PC) is a common tumor in Western countries. Several risk factors play significant roles. MYC, BIRC5/survivin, CDC25 and P53 may contribute to PC risk. As demonstrated, human Polyomavirus BK (BKV) could affect cellular homeostasis contributing to PC pathogenesis., Materials and Methods: Biological samples were collected from PC patients. Viral RNA was searched using quantitative polymerase chain reaction (PCR), whereas a qualitative PCR was employed to find particular viral sequences. Proper size amplicons were analyzed. Single nucleotide polymorphisms (SNPs) were detected in p53 coding regions by means of a specific PCR. C-MYC, BIRC5/survivin and CDC25 gene expression was investigated using a Retro Transcriptional Quantitative PCR., Results: Viral DNA copy number was higher in cancer tissues taken from Gleason score 9 patients with Gleason score 7. Different p53 mutated compared to patients exons were found according to tumor advanced stage and a statistical significant correlation was found between Gleason score and p53 mutational rate. C-MYC, BIRC5/survivin and CDC25 expression was de-regulated according to the literature., Conclusion: The presence of BKV and its variants in transformed cells does not exclude viral pressure in cell immortalization. Expression of other target genes evidenced a significant change in their regulation, useful for cancer drug discovery and therapies., (Copyright© 2015, International Institute of Anticancer Research (Dr. John G.

- Abstract
Objectives: To assess whether the proportion of men with clinically significant prostate cancer (PCa) is higher among men randomized to multiparametric magnetic resonance imaging (mp-MRI)/biopsy vs. those randomized to transrectal ultrasound (TRUS)-guided biopsy., Methods: In total, 1,140 patients with symptoms highly suggestive of PCa were enrolled and divided in 2 groups of 570 patients to follow 2 different diagnostic algorithms. Group A underwent a TRUS-guided random biopsy. Group B underwent an mp-MRI and a TRUS-guided targeted+random biopsy. The accuracy of mp-MRI in the diagnosis of PCa was calculated using prostatectomy as the standard of reference., Results: In group A, PCa was detected in 215 patients. The remaining 355 patients underwent an mp-MRI: the findings were positive in 208 and unremarkable in 147 patients. After the second random+targeted biopsy, PCa was detected in 186 of the 208 patients. In group B, 440 patients had positive findings on mp-MRI, and PCa was detected in 417 at first biopsy; 130 group B patients had unremarkable findings on both mp-MRI and biopsy. In the 130 group B patients with unremarkable findings on mp-MRI and biopsy, a PCa Gleason score of 6 or precancerous lesions were detected after saturation biopsy. mp-MRI showed an accuracy of 97% for the diagnosis of PCa., Conclusions: The proportion of men with clinically significant PCa is higher among those randomized to mp-MRI/biopsy vs. those randomized to TRUS-guided biopsy; moreover, mp-MRI is a very reliable tool to identify patients to schedule in active surveillance., (Copyright © 2014 Elsevier Inc.

- Abstract
Objectives: To describe our 10-year experience with the use of oral ethinylestradiol in the treatment of metastatic castration-resistant prostate cancer., Methods: From February 2000 to April 2010, 116 patients with a metastatic castration-resistant prostate cancer were prospectively submitted to oral ethinylestradiol monotherapy. Inclusion criteria were: diagnosis of castration-resistant prostate cancer after failure of at least two lines of androgen deprivation therapy and radiological evidence of metastases. Exclusion criteria were: symptomatic cases with a European Cooperative Oncology Group score >2 and severe or uncontrolled cardiovascular diseases. At inclusion in the study, all patients discontinued the previous androgen deprivation therapy and started oral ethinylestradiol at the daily dose of 1 mg. Aspirin (100 mg/daily) was concomitantly given., Results: The median ethinylestradiol therapy duration was 15.9 months (range 8-36 months), whereas the median follow up of patients was 28 months (range 13-36 months). During ethinylestradiol therapy, a confirmed prostate-specific antigen response was found in 79 patients (70.5%). The median time to prostate-specific antigen progression was 15.10 months (95% confidence interval 13.24-18.76 months). A toxicity requiring treatment cessation was observed in 26 patients (23.2%) at a median time of 16 months (mainly thromboembolism)., Conclusions: Our 10-year experience shows that ethinylestradiol provides a prostate-specific antigen response in a high percentage of patients with metastatic castration-resistant prostate cancer. Cardiovascular toxicity can be managed through accurate patient selection, close follow up and a concomitant anticoagulation therapy., (© 2014 The Japanese Urological Association.)

- Abstract
High-risk non-muscle invasive bladder cancer (NMIBC) progresses to metastatic disease in 10-15% of cases, suggesting that micrometastases may be present at first diagnosis. The prediction of risks of progression relies upon EORTC scoring systems, based on clinical and pathological parameters, which do not accurately identify which patients will progress. Aim of the study was to investigate whether the presence of CTC may improve prognostication in a large population of patients with Stage I bladder cancer who were all candidate to conservative surgery. A prospective single center trial was designed to correlate the presence of CTC to local recurrence and progression of disease in high-risk T1G3 bladder cancer. One hundred two patients were found eligible, all candidate to transurethral resection of the tumor followed by endovesical adjuvant immunotherapy with BCG. Median follow-up was 24.3 months (minimum-maximum: 4-36). The FDA-approved CellSearch System was used to enumerate CTC. Kaplan-Meier methods, log-rank test and multivariable Cox proportional hazard analysis was applied to establish the association of circulating tumor cells with time to first recurrence (TFR) and progression-free survival. CTC were detected in 20% of patients and predicted both decreased TFR (log-rank p < 0.001; multivariable adjusted hazard ratio [HR] 2.92 [95% confidence interval: 1.38-6.18], p = 0.005), and time to progression (log-rank p < 0.001; HR 7.17 [1.89-27.21], p = 0.004). The present findings provide evidence that CTC analyses can identify patients with Stage I bladder cancer who have already a systemic disease at diagnosis and might, therefore, potentially benefit from systemic treatment., (© 2014 UICC.)

- Abstract
Varicocele is the main cause of male infertility. Treatment stops continuous damage to spermatogenesis, thereby potentially improving fertility. Among all the available procedures, the ante-grade scrotal sclerotherapy (ASS), a combined radiological-surgical approach first introduced by Tauber, is gaining more popularity due to its minimal invasiveness. We report the case of a 35-year old man who was subjected to a colonic resection after antegrade scrotal sclerotherapy for varicocele. The procedure was necessary due to the embolization of venous anastomosis between the spermatic and mesenteric veins, which were not detectable at the preoperative phlebography.

- Abstract
Background: The outcome of benign convulsions associated with gastroenteritis (CwG) has generally been reported as being excellent. However, these data need to be confirmed in studies with longer follow-up evaluations., Aim: To assess the long-term neurological outcome of a large sample of children presenting with CwG., Methods: We reviewed clinical features of 81 subjects presenting with CwG (1994-2010) from three different Italian centers with a follow-up period of at least 3 years., Results: Follow-up period ranged from 39 months to 15 years (mean 9.8 years). Neurological examination and cognitive level at the last evaluation were normal in all the patients. A mild attention deficit was detected in three cases (3.7%). Fourteen children (17.3%) received chronic anti-epileptic therapy. Interictal EEG abnormalities detected at onset in 20 patients (24.7%) reverted to normal. Transient EEG epileptiform abnormalities were detected in other three cases (3.7%), and a transient photosensitivity in one (1.2%). No recurrence of CwG was observed. Three patients (3.7%) presented with a febrile seizure and two (2.5%) with an unprovoked seizure, but none developed epilepsy., Conclusions: The long-term evaluation of children with CwG confirms the excellent prognosis of this condition, with normal psychomotor development and low risk of relapse and of subsequent epilepsy., (Copyright © 2014 European Paediatric Neurology Society.

Gentile V, Frangipani E, Bonchi C, Minandri F, Runci F, and Visca P
- Abstract
Acinetobacter baumannii is an emerging nosocomial pathogen, responsible for infection outbreaks worldwide. The pathogenicity of this bacterium is mainly due to its multidrug-resistance and ability to form biofilm on abiotic surfaces, which facilitate long-term persistence in the hospital setting. Given the crucial role of iron in A. baumannii nutrition and pathogenicity, iron metabolism has been considered as a possible target for chelation-based antibacterial chemotherapy. In this study, we investigated the effect of iron restriction on A. baumannii growth and biofilm formation using different iron chelators and culture conditions. We report substantial inter-strain variability and growth medium-dependence for biofilm formation by A. baumannii isolates from veterinary and clinical sources. Neither planktonic nor biofilm growth of A. baumannii was affected by exogenous chelators. Biofilm formation was either stimulated by iron or not responsive to iron in the majority of isolates tested, indicating that iron starvation is not sensed as an overall biofilm-inducing stimulus by A. baumannii. The impressive iron withholding capacity of this bacterium should be taken into account for future development of chelation-based antimicrobial and anti-biofilm therapies.

- Abstract
Purpose: Regulation of the apoptotic process has an important role in spermatogenesis. p53 has a prominent function in apoptosis and recent data suggest a relationship between varicocele and p53 codon 72 polymorphism and male infertility. This prompted us to study the relationship between this polymorphism and spermatic parameters., Methods: We studied 134 subjects with varicocele admitted consecutively to the outpatients Department of Infertility at the University of Rome La Sapienza. We investigated in these subjects the effect of a strong apoptosis inducer, the p53 codon 72 *Arg/*Arg genotype, on spermatic parameters.The p53 codon 72 genotype was determined by DNA analysis., Results: The proportion of spermatozoa with abnormal (curvilinear) motility is higher in men with the *Arg/*Arg genotype than in men carrying the *Pro allele ( p = 0.003). No statistical significant relationship has been observed with spermatozoa concentration and atypical spermatozoa., Conclusions: We conclude: the p53 codon 72*Arg/*Arg genotype, with its strong apoptotic effects, negatively influences spermatozoa motility and male fertility., Competing Interests: Vincenzo Gentile, Maria Nicotra, Sergio Minucci, Sara Ambrosi, Patrizia Saccucci, Fulvia Gloria‐Bottini and Egidio Bottini declare that they have no conflict of interest.

- Abstract
Background: Bacterial prostatitis (BP) is a common condition accounting responsible for about 5-10% of all prostatitis cases; chronic bacterial prostatitis (CBP) classified as type II, are less common but is a condition that significantly hampers the quality of life, (QoL) because not only is it a physical condition but also a psychological distress. Commonly patients are treated with antibiotics alone, and in particular fluoroquinolones are suggested by the European Urology guidelines. This approach, although recommended, may not be enough. Thus, a multimodal approach to the prolonged antibiotic therapy may be helpful., Methods: 210 patients affected by chronic bacterial prostatitis were enrolled in the study. All patients were positive to Meares-Stamey test and symptoms duration was > 3 months. The purpose of the study was to evaluate the efficacy of a long lasting therapy with a fluoroquinolone in association with a nutraceutical supplement (prulifloxacin 600 mg for 21 days and an association of Serenoa repens 320 mg, Lactobacillus Sporogens 200 mg, Arbutin 100 mg for 30 days). Patients were randomized in two groups (A and B) receiving respectively antibiotic alone and an association of antibiotic plus supplement., Results: Biological recurrence at 2 months in Group A was observed in 21 patients (27.6%) and in Group B in 6 patients (7.8%). Uropathogens found at the first follow-up were for the majority Gram - (E. coli and Enterobacter spp.). A statistically significant difference was found at the time of the follow-up between Group A and B in the NIH-CPSI questionnaire score, symptoms evidence and serum PSA., Conclusions: Broad band, short-lasting antibiotic therapy in association with a nutritional supplement (serenoa repens, lactobacillus sporogens and arbutin) show better control and recurrence rate on patients affected by chronic bacterial prostatitits in comparison with antibiotic treatment alone., Trial Registration: NCT02130713.
