Supine mini percutaneous nephrolithotomy in horseshoe kidney.

OBJECTIVE: The percutaneous nephrolithotomy (PCNL) in Horseshoe kidneys (HSK) is usually performed in the prone position, allowing entry through the upper pole and providing good access to the collecting system. However, in patients with normal kidney anatomy, the supine position is reliable and safe in most cases, but it is unknown whether the supine position is adequate in patients with HSK. The purpose of this study was to describe the results of PCNL in HSK in three different surgical institutions and to evaluate the impact of supine position during surgery, comparing pre-operative and post-operative data, complications, and stone status after surgery. MATERIAL AND METHODS: Between 2017 and 2022, a total of 10 patients underwent percutaneous renal surgery for stone disease in HSK. All patients were evaluated pre- and post- operatively with non-contrast CT. we evaluated patients (age and gender), stones characteristics (size, number, side, site and density ), and outcomes. The change in haemoglobin, hematocrit, creatinine and eGFr were assessed between the most recent preoperative period and the first postoperative day. Procedure success was defined as stone-free or presence of ≤4 mm fragments (Clinically Insignificant residual Fragments - CIrF). Complications were registered and classified according to Clavien-dindo Grading System, during the 30 - day postoperative period and Clavien scores ≥ 3 were considered as major complications. Statistical analysis was performed using "r 4.2.1" software, with a 5% significance level. we also compared pre-operative and post-operative data using "wilcoxon signedrank test". RESULTS: No statistical difference was observed between preoperative and post-operative renal function data. At one post operative day CT scan, an overall success rate of 100% was registered. 9/10 patients were completely free from urolithiasis (stone-free rate: 90%), while 1/10 patients had ≤4 mm residual stone fragments (CIrF rate: 10%). No cases of intraoperative complications were registered. Post-operative complications were reported in 1/10 patients. A patient developed urosepsis (defined as SIrS with clinical signs of bacterial infections involving urogenital organs - Clavien-dindo Grade II) after procedure, and was treated with intravenous antibiotic therapy successfully.  Conclusions: This study shows that in patients with HSK mini- PCNL in supine position allows to achieve good stone free rate with a very low morbidity. According to our series, the described technique for PCNL in HSK should be an option. Nevertheless these results must be confirmed by further studies.

Physical exercise in asthma adolescents: a concept review.

Background: Asthma is a frequent pathological condition during childhood and adolescence. Young asthmatics demonstrate decreased aptitude for physical activity and a limited exercise capacity. Lower hospitalisation rates, reduced school absenteeism, fewer medical examinations, and limited use of bronchodilators have been documented in children and adolescents with bronchial asthma who engage in physical exercise regularly. Structured physical exercise protocols should be encouraged as they can work as a synergistic therapeutic option in addition to regular pharmacologic treatment. This article outlines the most suitable exercise training techniques for young patients with bronchial asthma and their effects on health status.

A Proposal of a New Nomogram to Predict the Need for Testosterone ReplACEment (TRACE): A Simple Tool for Everyday Clinical Practice.

International guidelines suggest to use testosterone therapy (TTh) in hypogonadal men presenting symptoms of testosterone deficiency (TD), even if there is no fixed threshold level of T at which TTh should be started. We aimed to develop and validate a nomogram named TRACE (Testosterone ReplACEment) for predicting the need of TTh in patients with "low-normal" total testosterone levels. The following nomogram variables were used: serum T level; serum LH level; BMI; state of nocturnal erections; metabolic comorbidities; and IPSS total score. The nomogram has been tested by calculating concordance probabilities, as well as assaying the calibration of predicted probability of clinical testosterone deficiency and need for TTh, together with the clinical outcome of the TTh. A cohort of 141 patients was used for the development of the nomogram, while a cohort of 123 patients attending another institution was used to externally validate and calibrate it. Sixty-four patients (45.3%) received TTh. Among them, sixty patients (93.7%) reported a significant clinical improvement after TTh. The nomogram had a concordance index of 0.83 [area under the ROC curve 0.81 (95% CI 0.71-0.83)]. In conclusion, the TRACE nomogram accurately predicted the probability of clinical impairment related to TD, and resulted in a simple and reliable method to use to select hypogonadal patients with not clearly pathological testosterone values who will benefit from TTh.

Longitudinal Impact of Social Restrictions on Sexual Health in the Italian Population.

BACKGROUND: Several trials have reported on the impact of social restrictions due to SARS-CoV-2 (COVID-19) pandemic on sexual function and psycho-physical well-being. However, data showing modifications of these outcomes over time and at the end of lock-down are scant. AIM: We investigated the longitudinal changes in sexual function during social restrictions for COVID-19 pandemic in Italy. METHODS: A web-based survey was administered to Italian citizens of legal age via social networks. The Beck Depression Inventory Primary Care, the General Health Survey, Female Sexual Function Index, International Index of Erectile Function, UCLA Loneliness Scale-version 3 questionnaires were used to test mental, physical and sexual well-being. The questionnaires were administered at the beginning of the lockdown (T0), 15 days from the first assessment (T1) and 1 month after the end of the restrictions in 2020 (T2). OUTCOMES: Descriptive statistics and multiple regression analysis were applied to investigate changes in sexual function over and at the end of social restrictions. RESULTS: Data were available for 2543 people (47.2% of men; 43.4% women; 9.4% undefined). Mean age was 48.3 ± 15.1 years for males and 43.9 ± 13.4 for females. Overall, 2.6% reported depressive symptoms according to Beck Depression Inventory Primary Care, 7.4% reported a high level of UCLA loneliness and 19.4% low levels of general mental health. Mild to severe erectile dysfunction was reported by 59.1% of men at T0, while 68.4% of women reported sexual dysfunction. Sexual function levels remain generally unchanged at further follow-up over the social restriction time period (T1), although those who were sexually active at baseline showed a decrease in sexual function scores. At T2, there was an overall improvement in sexual function scores with a rate of severe erectile dysfunction decreasing from 37.1% to 24.1% from T0 to T2 among males and a significant decrease of female sexual dysfunction from 68.4% to 51.2%. CLINICAL IMPLICATIONS: Young individuals and those with good mental and physical health were more likely to improve sexual function at the end of social restrictions. STRENGTHS & LIMITATIONS: Valid and reliable questionnaires and longitudinal approach design represent strengths; a large but convenient sample and lack of pre-pandemic baseline data represent limits. CONCLUSION: Social restrictions due to COVID-19 pandemic led to an increase in sexual dysfunctions in both genders. However, these conditions appeared temporary since an overall improvement was observed at the end of lockdown and especially in younger individuals with higher psycho-physical well-being.

Prevalence and clinical features of most frequent phenotypes in the Italian COPD population: the CLIMA Study.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a complex, progressive respiratory condition characterized by heterogeneous clinical presentations (phenotypes). The aim of this study was to assess the prevalence of the main COPD phenotypes and match of each phenotype to the most fitting clinical and lung function profile. METHODS: the CLIMA (Clinical Phenotypes in Actual Clinical Practice) study was an observational, cross-sectional investigation involving twenty-four sites evenly distributed throughout Italy. Patients were tentatively grouped based on their history and claimed prevailing symptoms at recruitment: chronic cough (CB, suggesting chronic bronchitis); dyspnoea (possible emphysema components, E); recurrent wheezing (presuming asthma components, A). Variables collected were: anagraphics; smoking habit; history of asthma; claim of >1 exacerbations in the previous year; blood eosinophil count; total blood IgE and alpha1 anti-trypsin (α1-AT) levels; complete lung function, and the chest X-ray report. mMRC, CAT, BCS, EQ5d-5L were also used. The association between variables and phenotypes were checked by Chi-square test and multinomial logistic regression. RESULTS: The CB phenotype was prevalent (48.3%), followed by the E and the A phenotypes (38.8% and 12.8%, respectively). When dyspnoea was the prevailing symptom, the probability of belonging to the COPD-E phenotype was 3.40 times higher. Recurrent wheezing was mostly related to the COPD-A phenotype. Lung function proved more preserved in the COPD-CB phenotype. Smoke; n. exacerbations/year; VR, and BODE index were positively correlated with the COPD-E phenotype, while SpO2, FEV1/FVC, FEV1/VC, and FEV1 reversibility were negatively correlated. Lower DLco values were highly probative for the COPD-E phenotype (p<0.001). Conversely, smoke, wheezing, plasma eosinophils, FEV1 reversibility, and DLco were positively correlated with the COPD-A phenotype. The probability of belonging to the COPD-A phenotype raised by 2.71 times for any increase of one unit in % plasma eosinophils (p<0.001). Also multiparametrical scores contributed to discriminate the three phenotypes. CONCLUSION: The recognition of the main phenotypes of COPD can be effectively pursued by means of a few clinical and instrumental parameters, easy to obtain also in current daily practice. The phenotypical approach is crucial in the management of COPD as it allows to individualize the therapeutic strategy and to obtain more effective clinical outcomes.

Evaluation of the "Teaching Guide for Basic Laparoscopic Skills" as a stand-alone educational tool for hands-on training sessions: a pilot study.

INTRODUCTION AND OBJECTIVES: Standardization of hands-on training (HoT) has profoundly impacted the educational field in the last decade. To provide quality training sessions on a global scale, the European School of Urology Training group developed a teaching guide for tutors in 2015. Our study aims to understand whether this guide alone can provide information enough to match the performance improvement guaranteed by an expert tutor. MATERIAL AND METHODS: 4 randomized groups of participants underwent HoT sessions with different teaching modalities: an expert surgeon (group 1), an expert E-BLUS tutor (group 2), E-BLUS guide alone (group 3), no tutor (group 4). Groups 1 and 2 were respectively provided with two different tutors to avoid biases related to personal tutor ability. Along the training session, each participant could perform five trials on two E-BLUS tasks: Peg transfer and Knot tying. During trials 1 and 5, completion time and number of errors were recorded for analysis with Pi-score algorithm. The average per-group Pi-scores were then compared to measure different performance improvement results. RESULTS: 60 participants from Italy were enrolled and randomized into four groups of 15. Pi-scores recorded on Peg transfer task were 24,6 (group 1), 26,4 (group 2), 42,2 (group 3), 11,7 (group 4). Pi-scores recorded on Knot tying task were 33,2 (group 1), 31,3 (group 2), 37,5 (group 3), 18,6 (group 4). CONCLUSION: Compared to a human tutor, standardized teaching with the EBLUS guide may produce similar performance improvement. This evidence opens doors to automated teaching and to several novelties in hands-on training.

COVID-19 pandemic and its implications on sexual life: Recommendations from the Italian Society of Andrology.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the coronavirus that causes an infectious disease, called COVID-19, first detected in patients with pneumonia in Wuhan (People's Republic of China) on December 2019. Italy was the first European country to state the outbreak of the infection and its Council of Ministers declared the state of health emergency on 31.01.2020, then the World Health Organization ruled a global pandemic on 11.03.2020. The nasopharyngeal swab is based on the detection of virus RNA and is the only reliable one for declaring COVID-19 infection. The most common symptoms observed in COVID-19 patients before hospitalization may be fever, chills, cough, dyspnea, asthenia, myalgia and/or arthralgia. This symptomatology can be often complicated in a dramatically increasing manner such as to require hospitalization starting from the third-fourth week. COVID-19 outbreak has dramatically affected the quality of life by changing inter-personal relationships, community life and obviously sexual health. The purpose of this work, based on available evidence, is to provide recommendations to help the population to face their sexual life in this critical period.

Pharmacotherapeutic management of lower urinary tract symptoms in Multiple Sclerosis patients.

INTRODUCTION: Multiple Sclerosis (MS) manifests with a plethora of signs and symptoms affecting brain structures and spinal pathways. The multitude of lesions in MS patients makes difficult to establish the relative role of each of them to lower urinary tract symptoms (LUTS). Generally, the subcortical white-matter lesions result in detrusor overactivity, whilst lesions of the spinal cord result in the combined occurrence of detrusor overactivity and detrusor-sphincter dyssynergia (DSD). It has been estimated that 80-90% of patients with MS will suffer from some form of LUTS over the course of the disease. Among LUTS, the most reported is detrusor overactivity which includes urinary urgency, frequent urination, nocturia, and urge urinary incontinence. AREAS COVERED: The authors review the management of lower urinary tract symptoms in MS patients providing their expert opinions on the subject matter. EXPERT OPINION: LUTS affect the quality of life substantially and are associated with a significantly increased mortality. The adequate management is an important challenge for both patients and caregivers with a multidisciplinary approach likely necessary.

Adherence to Mediterranean diet and prostate cancer risk in Sicily: population-based case-control study.

Prostate cancer (PCa) is the second most frequently diagnosed cancer and the sixth leading cause of death from cancer worldwide. Countries following a Mediterranean-type dietary pattern, has been reported to have lower PCa incidence and mortality compared with other European regions. A population-based case-control study has been conducted from January 2015 to December 2016 in a single institution of the municipality of Catania, southern Italy. A total of 118 PCa and 238 population-based controls were collected. Controls had significantly higher adherence to the Mediterranean diet, which was evident for several subgroups (including age groups, overweight and obese men, current smokers, alcohol intake, low and medium physical activity levels). PCa cases were found to consume lower amount of vegetables (223 g/d vs. 261 g/d; p = 0.001), legumes (34.26 g/d vs. 53.55 g/d; p = 0.003), and fish (47.75 g/d vs. 58.3 g/d) than controls; other differences emerged were related to alcohol intake (12.37 g/d vs 5.07 g/d; p < 0.01), cereals (254.06 g/d vs.235.94 g/d; p < 0.001), dairy (196 g/d vs. 166 g/d; p < 0.001), and meat consumption (98.09 g/d vs. 70.15 g/d; p < 0.001). However, no statistically significant differences between cases and controls were found regarding fruit, legumes, and olive oil consumption. The Mediterranean diet score was inversely associated with lower likelihood of having PCa in a linear manner (odds ratio [OR]: 0.86 [95% CI 0.77-0.96]). Specifically, individuals in the highest group of adherence had 78% less likelihood of have PCa and 14% less likelihood for each point increase of the score. The model adjusted for total polyphenol intake showed still a significant inverse association between adherence to the Mediterranean diet and PCa, but the relation was no more linear and not significant for one-point increase of the score (OR: 0.88 [95% CI 0.77-1.01]). In our cohorts of Italian men, we observed that high adherence to the Mediterranean diet was inversely associated with likelihood of having PCa cancer.

Active Surveillance for Low-risk Prostate Cancer: Are All Criteria Similar?

BACKGROUND: Active Surveillance (AS) is a therapeutic strategy for early-stage Prostate Cancer (PCa) conceived to balance early detection of aggressive disease and overtreatment of indolent tumor. Several active surveillance protocols have been published over the years, however the risk of misclassification still exist. In this review, we revised the current criteria of AS and evaluated the characteristics of potential risk factors of misclassification or deferred treatment. METHODS: We did a systematic search of the MEDLINE database, from 1993 to May 2015, according to Preferred Reporting Items for Systematic Reviews and Meta-analysis statement guidelines and limited to the English language. The search terms used included "prostate cancer" and "active surveillance" and "criteria. We have excluded from the study reviews and editorial comments as well as multiple papers from the same data sets. RESULTS: Although the follow-up of reported studies was a quite short compared to the duration of the disease, the data are sufficient to conclude that active surveillance should be offered to men with low-risk disease and to men with intermediate risk and poor life expectancy. The present challenge, in fact, is to differentiate the clinically silent disease from the unfavorable course by identifying the right timing for any deferred treatment. This is made particularly difficult by the absence of randomized controlled trials directly comparing different AS monitoring methods. CONCLUSION: As summarized in this review, it is still difficult to select patients eligible for active surveillance and differentiate them from those that should move to active treatment. From the data, currently available in the literature, however, it is possible to recommend active surveillance to men with low-risk disease and to men with intermediate-risk disease but with short life expectancy.

Metabolic syndrome is not associated with greater evidences of proliferative inflammatory atrophy and inflammation in patients with suspected prostate cancer.

INTRODUCTION AND OBJECTIVES: To evaluate the association between metabolic syndrome (MetS) and proliferative inflammatory atrophy (PIA) in patients with suspected prostate cancer (PCa). PATIENTS AND METHODS: From June 2015 to July 2016, we conducted the FIERY (Flogosis Increased Events of pRostatic biopsY) study at the Urology section, Department of Surgery of the University of Catania (Local registration number: #131/2015). A total of 205 patients with elevated prostate-specific antigen (≥ 4 ng/ml) or clinical suspicion of PCa who underwent primary transperineal prostate biopsy were included in this cross-sectional study. The assessment of PIA, HGPIN, and PCa were performed by 2 experienced pathologists and samples were investigated for the presence of an inflammatory infiltrate, according to the Irani score. Primary and secondary Gleason grade of tumor in positive biopsies were evaluated according to the 2016 ISUP Modified Gleason System. RESULTS: In the entire cohort, median age was 68.0 (interquartile range: 62.0-74.5), median prostate-specific antigen was 6.5 (interquartile range: 5.51-9.57). The prevalence of MetS was 34.1%, the detection rate of PCa was 32.7%, the rate of PIA was 28.3%, the rate of HGPIN was 32.2%, whereas the rate of severe intraprostatic inflammation (Irani-score ≥4) was 28.8%. When comparing clinical and histological variables in patients without and with PIA, metabolic aberrations where not significantly different in both groups. We did not find statistical association in detection rate of PCa (29.3% vs. 34.0%; P = 0.07) and HGPIN (27.6% vs. 34.0%; P = 0.37) in patients with and without PIA, respectively. When considering metabolic aberrations, MetS was not associated with Irani-score ≥4 (28.6% vs. 28.4%; P = 0.96) and none of each component was statistically predictive of severe inflammation. At the multivariable logistic regression analysis, PIA, HGPIN, and MetS were not associated with greater risk of PCa. CONCLUSION: In this study, we did not show an association between MetS and PIA and PCa. Although the small sample size and the cross-sectional nature of the study, we do not suppose that MetS could be associated with greater evidence of PIA. Further studies should be conducted to evaluate the exact nature of this pathological lesion.

Latest Evidence on the Role of Multiparametric Magnetic Resonance Imaging in Active Surveillance for Insignificant Prostate Cancer: A Systematic Review.

OBJECTIVE: Multiparametric Magnetic Resonance Imaging (mpMRI) has become a very useful tool in the management of PCa. Particularly, there is a great interest in using mpMRI for men on Active Surveillance (AS) for low risk PCa. The aim of this systematic review was to critically review the latest literature concerning the role of mpMRI in this clinical setting, underlying current strengths and weakness. EVIDENCE ACQUISITION: A comprehensive literature research for English-language original and review articles was carried out using the National Center for Biotechnology Information PubMed database with the aim to identify studies pertaining to mpMRI for AS in low risk PCa patients. The following search terms were used: active surveillance, prostate cancer and multiparametric magnetic resonance imaging. EVIDENCE SYNTHESIS: Data from 28 recent original studies and reviews were reviewed. We only considered studies on the use of mpMRI in selecting AS patients and during AS follow-up, in order to solve two important questions: -Can mpMRI have a role in improving the detection of clinically significant disease, better selecting AS patients? -Can mpMRI identify the progression of disease and, consequently, be used during AS follow-up? CONCLUSIONS: mpMRI is useful to better select the ideal candidates to AS and to monitor them during follow-up. However, despite many advantages, there are yet important limitations to detect all clinically significant PCa and to better define mpMRI-radiological progression during AS. Further larger prospective studies are needed to definitively solve these important problems.

COPD management as a model for all chronic respiratory conditions: report of the 4th Consensus Conference in Respiratory Medicine.

BACKGROUND: Non-communicable diseases (NCDs) kill 40 million people each year. The management of chronic respiratory NCDs such as chronic obstructive pulmonary disease (COPD) is particularly critical in Italy, where they are widespread and represent a heavy burden on healthcare resources. It is thus important to redefine the role and responsibility of respiratory specialists and their scientific societies, together with that of the whole healthcare system, in order to create a sustainable management of COPD, which could become a model for other chronic respiratory conditions. METHODS: These issues were divided into four main topics (Training, Organization, Responsibilities, and Sustainability) and discussed at a Consensus Conference promoted by the Research Center of the Italian Respiratory Society held in Rome, Italy, 3-4 November 2016. RESULTS AND CONCLUSIONS: Regarding training, important inadequacies emerged regarding specialist training - both the duration of practical training courses and teaching about chronic diseases like COPD. A better integration between university and teaching hospitals would improve the quality of specialization. A better organizational integration between hospital and specialists/general practitioners (GPs) in the local community is essential to improve the diagnostic and therapeutic pathways for chronic respiratory patients. Improving the care pathways is the joint responsibility of respiratory specialists, GPs, patients and their caregivers, and the healthcare system. The sustainability of the entire system depends on a better organization of the diagnostic-therapeutic pathways, in which also other stakeholders such as pharmacists and pharmaceutical companies can play an important role.

A phase II, randomized, single-blinded, placebo-controlled clinical trial on the efficacy of Curcumina and Calendula suppositories for the treatment of patients with chronic prostatitis/chronic pelvic pain syndrome type III.

OBJECTIVE: The management of chronic prostatitis/ chronic pelvic pain syndrome type III (CP/CPPS) has been always considered complex due to several biopsychological factors underling the disease. In this clinical study, we aimed to evaluate the efficacy of the treatment with Curcumin and Calendula extract in patients with CP/CPPS III. MATERIAL AND METHODS: From June 2015 to January 2016 we enrolled 60 consecutive patients affected by CP/CPPS III in our institution. Patients between 20 and 50 year of age with symptoms of pelvic pain for 3 months or more before study, a total National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) score ≥ 15 point and diagnosed with NIH category III. Patients were then allocated to receive placebo (Group A) or treatment (Group B). Treatment consisted of rectal suppositories of Curcumin extract 350 mg (95%) and Calendula extract 80 mg (1 suppository/die for 1 month). Patients of Group B received 1 suppository/die for 1 month of placebo. The primary endpoint of the study was the reduction of NIH-CPSI. The secondary outcomes were the change of peak flow, IIEF-5, VAS score and of premature ejaculation diagnostic tool (PEDT). RESULTS: A total of 48 patients concluded the study protocol. The median age of the all cohort was 32.0 years, the median NIH-CPSI was 20.5, the median IIEF-5 was 18.5, the median PEDT was 11.0, the median VAS score was 7.5 and the median peak flow was 14.0. After 3 months of therapy in group A we observed a significant improvement of NIH-CPSI (-5.5; p < 0.01), IIEF-5 (+ 3.5; p < 0.01), PEDT (-6.5; p < 0.01), peak flow (+2.8; p < 0.01) and VAS (-6.5; p < 0.01) with significant differences over placebo group (all p-value significant). CONCLUSIONS: In this phase II clinical trial we showed the clinical efficacy of the treatment with Curcumin and Calendula in patients with CP/CPPS III. The benefits of this treatment could be related to the reduction of inflammatory cytokines and of inflammatory cells. These results should be confirmed in further studies with greater sample size.

Comparison between Briganti, Partin and MSKCC tools in predicting positive lymph nodes in prostate cancer: a systematic review and meta-analysis.

OBJECTIVE: The aim of this study was to analyze the discriminative capabilities of Briganti, Partin and Memorial Sloan Kettering Cancer Center (MSKCC) nomograms in predicting lymph-node invasion (LNI) and to perform a meta-analysis to yield pooled area under the receiver operating characteristics curves (AUCs) for model comparison. MATERIALS AND METHODS: An electronic search of the MEDLINE and Embase databases up to October 2016 was undertaken. The AUC value, total number of patients and rate of LNI were extracted from the included references. After excluding redundant literature, 19 studies were identified including 86,338 patients. The Briganti, Partin and MSKCC nomograms were validated in 6629, 69,681 and 10,028 patients, respectively. RESULTS: The pooled AUCs for Briganti, Partin, and MSKCC nomograms were 0.793, 0.778 and 0.780, respectively. The Mantel-Haenszel-derived comparison of AUC values revealed no statistical differences of predictive capabilities for Briganti vs Partin (p = 0.23), Briganti vs MSKCC (p = 0.83) and Partin vs MSKCC (p = 0.26). The accuracy of Briganti, Partin and MSKCC models is statistically similar in predicting the presence of LNI. International guidelines could consider these findings by reporting similarities in the accuracy of these models. CONCLUSIONS: The accuracy of Briganti, Partin and MSKCC was similar in predicting the presence of LNI. Based on these results, patients and clinicians may use any of these nomograms without significant advantages.

Survivin and NAIP in Human Benign Prostatic Hyperplasia: Protective Role of the Association of Serenoa repens, Lycopene and Selenium from the Randomized Clinical Study.

Benign prostatic hyperplasia (BPH) treatment includes the apoptosis machinery modulation through the direct inhibition of caspase cascade. We previously demonstrated that Serenoa repens (Ser) with lycopene (Ly) and selenium (Se) reawakened apoptosis by reducing survivin and neuronal apoptosis inhibitory protein (NAIP) levels in rats. The aim of this study was to evaluate the effectiveness of Ser-Se-Ly association on survivin and NAIP expression in BPH patients. Ninety patients with lower urinary tract symptoms (LUTS) due to clinical BPH were included in this randomized, double-blind, placebo-controlled trial. Participants were randomly assigned to receive placebo (Group BPH + placebo, n = 45) or Ser-Se-Ly association (Group BPH + Ser-Se-Ly; n = 45) for 3 months. At time 0, all patients underwent prostatic biopsies. After 3 months of treatment, they underwent prostatic re-biopsy and specimens were collected for molecular, morphological, and immunohistochemical analysis. After 3 months, survivin and NAIP were significantly decreased, while caspase-3 was significantly increased in BPH patients treated with Ser-Se-Ly when compared with the other group. In BPH patients treated with Ser-Se-Ly for 3 months, the glandular epithelium was formed by a single layer of cuboidal cells. PSA showed high immunoexpression in all BPH patients and a focal positivity in Ser-Se-Ly treated patients after 3 months. Evident prostate specific membrane antigen (PSMA) immunoexpression was shown in all BPH patients, while no positivity was present after Ser-Se-Ly administration. Ser-Se-Ly proved to be effective in promoting apoptosis in BPH patients.

A Systematic Review and Meta-analysis of the Diagnostic Accuracy of Prostate Health Index and 4-Kallikrein Panel Score in Predicting Overall and High-grade Prostate Cancer.

Markers for prostate cancer (PCa) have progressed over recent years. In particular, the prostate health index (PHI) and the 4-kallikrein (4K) panel have been demonstrated to improve the diagnosis of PCa. We aimed to review the diagnostic accuracy of PHI and the 4K panel for PCa detection. We performed a systematic literature search of PubMed, EMBASE, Cochrane, and Academic One File databases until July 2016. We included diagnostic accuracy studies that used PHI or 4K panel for the diagnosis of PCa or high-grade PCa. The methodological quality was assessed using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool. Twenty-eight studies including 16,762 patients have been included for the analysis. The pooled data showed a sensitivity of 0.89 and 0.74 for PHI and 4K panel, respectively, for PCa detection and a pooled specificity of 0.34 and 0.60 for PHI and 4K panel, respectively. The derived area under the curve (AUC) from the hierarchical summary receiver operating characteristic (HSROC) showed an accuracy of 0.76 and 0.72 for PHI and 4K panel respectively. For high-grade PCa detection, the pooled sensitivity was 0.93 and 0.87 for PHI and 4K panel, respectively, whereas the pooled specificity was 0.34 and 0.61 for PHI and 4K panel, respectively. The derived AUC from the HSROC showed an accuracy of 0.82 and 0.81 for PHI and 4K panel, respectively. Both PHI and the 4K panel provided good diagnostic accuracy in detecting overall and high-grade PCa.

Neutrophil to lymphocyte ratio, a biomarker in non-muscle invasive bladder cancer: a single-institutional longitudinal study.

BACKGROUND: Bladder cancer represents one of the most important clinical challenges in urologic practice. In this context, inflammation has an important role in the development and progression of many malignancies. The objective of the present study was to evaluate the prognostic value of pre-treatment Neutrophil to lymphocyte ratio (NLR) on the risk of recurrence and progression in patients with primary non-muscle invasive bladder cancer. MATERIALS AND METHODS: Data obtained from 178 bladder cancer patients who underwent transurethral resection of bladder tumor (TURB) between July 2008 and December 2014 were evaluated prospectively. NLR was obtained from each patient before TURB and defined as the absolute neutrophil count divided by the absolute lymphocyte count. Cox proportional hazards regression model was performed to calculate disease recurrence and progression including NLR. RESULTS: During the follow-up study (median: 53 months), 14 (23.3%) and 44 (37.9%) (p=0.04) patients respectively with NLR<3 and ≥3experienced recurrence and 2 (3.3%) and 14 (11.9%) experienced progression (p=0.06), respectively. At the multivariate Cox regression analysis, NLR ≥3 was associated with worse disease recurrence (HR: 2.84; p<0.01). No association was found regarding disease progression. The 5-year recurrence free survival was 49% and 62% in patients with NLR≥3 and <3 (p<0.01). The 5-year progression free survival was 77% and 93% in patients with NLR≥3 and <3 (p=0.69). CONCLUSION: NLR predicts disease recurrence but not disease progression in NMIBC patients. NLR alterations may depend of tumor inflammatory microenvironment.

Results: During the follow-up study (median: 53 months), 14 (23.3%) and 44 (37.9%) (p=0.04) patients respectively with NLR<3 and ≥3experienced recurrence and 2 (3.3%) and 14 (11.9%) experienced progression (p=0.06), respectively. At the multivariate Cox regression analysis, NLR ≥3 was associated with worse disease recurrence (HR: 2.84; p<0.01). No association was found regarding disease progression. The 5-year recurrence free survival was 49% and 62% in patients with NLR≥3 and <3 (p<0.01). The 5-year progression free survival was 77% and 93% in patients with NLR≥3 and <3 (p=0.69). Conclusion: NLR predicts disease recurrence but not disease progression in NMIBC patients. NLR alterations may depend of tumor inflammatory microenvironment.

Impact of combination therapy 5-alpha reductase inhibitors (5-ARI) plus alpha-blockers (AB) on erectile dysfunction and decrease of libido in patients with LUTS/BPH: a systematic review with meta-analysis.

Lower urinary tract symptoms (LUTS) secondary to benign prostatic obstruction (BPO) represent one of the most common clinical complaints in adult men. Several drugs used for LUTS/BPO may strongly affect sexual function and bother. The aim of this systematic review and meta-analysis was to evaluate the impact of combination therapy with alpha-blockers (AB), 5-alpha reductase inhibitors (5-ARI) on the risk of erectile dysfunction(ED) and libido alterations (LA) from randomized clinical trial (RCT). Based on the inclusion and exclusion criteria, five RCTs involving 6131 patients were included in the analysis. According to the analysis, the overall prevalence of ED and LA were significantly greater in the combination treatment group than in the AB group (7.93% versus 4.66%; OR 1.81; p < 0.0001 and 3.69% versus 2.36%; OR 1.58; p = 0.003, respectively). The combination therapy increased the risk of ED compared to monotherapy with 5-ARI (7.93% versus 6.47%; OR 1.25; p = 0.04) but not the risk of LA (3.51% versus 3.37; OR 1.03; p = 0.84). In our systematic meta-analysis, we demonstrated that combination therapy with ABs and 5-ARIs was associated with significantly higher risk of ED and LA compared with single monotherapy. Combination therapy showed similar risk of LA compared with 5-ARI monotherapy.
