External validation of a nomogram for outcome prediction in management of medium-sized (1-2 cm) kidney stones.

BACKGROUND: Stone nomogram by Micali et al., able topredict treatment failure of shock-wave lithotripsy (SWL), retrograde intrarenal surgery (RIRS) and percutaneous nephrolithotomy (PNL) in the management of single 1-2 cm renal stones, was developed on 2605 patients and showed a high predictive accuracy, with an area under ROC curve of 0.793 at internal validation. The aim of the present study is to externally validate the model to assess whether it displayed a satisfactory predictive performance if applied to different populations. METHODS: External validation was retrospectively performed on 3025 patients who underwent an active stone treatment from December 2010 to June 2021 in 26 centers from four countries (Italy, USA, Spain, Argentina). Collected variables included: age, gender, previous renal surgery, preoperative urine culture, hydronephrosis, stone side, site, density, skin-to-stone distance. Treatment failure was the defined outcome (residual fragments >4 mm at three months CT-scan). RESULTS: Model discrimination in external validation datasets showed an area under ROC curve of 0.66 (95% 0.59-0.68) with adequate calibration. The retrospective fashion of the study and the lack of generalizability of the tool towards populations from Asia, Africa or Oceania represent limitations of the current analysis. CONCLUSIONS: According to the current findings, Micali's nomogram can be used for treatment prediction after SWL, RIRS and PNL; however, a lower discrimination performance than the one at internal validation should be acknowledged, reflecting geographical, temporal and domain limitation of external validation studies. Further prospective evaluation is required to refine and improve the nomogram findings and to validate its clinical value.

Use of etonogestrel subcutaneous implant in Sardinia, Italy: women's compliance and satisfaction.

PURPOSE OF THE ARTICLE: The main aim of the study was to analyze the population of women who used etonogestrel implant, the reason that led them to this type of contraception, and the degree of compliance with it. Materials and methods: We carried out a retrospective study on women who had etonogestrel subcutaneous implant placed (n°47) over a 6-year period (2015-2021). We submitted the women a series of questions by telephone questionnaire (range 10-72 months after placements, mean 40 months) that investigated the comorbidities and side effects related to etonogestrel implant. MATERIALS AND METHODS: We carried out a retrospective study on women who had etonogestrel subcutaneous implant placed (n°47) over a 6-year period (2015-2021). We submitted the women a series of questions by telephone questionnaire (range 10-72 months after placements, mean 40 months) that investigated the comorbidities and side effects related to etonogestrel implant. RESULTS: The average age of placement of etonogestrel implant was 33.8 ± 3.45 years. As regards level of education, 16/47 (34%) of the women had a university degree, 21/47 (44%) had a high school diploma and 10/47 (21%) had a secondary school diploma. The 12/47 (25%) of the women were, at the time of the counselling, unemployed and only 8% did not use in the past contraceptive methods other than etonogestrel implant. The 92% of women choose etonogestrel implant because it offered safe, comfortable and long-lasting contraception. Among the main side effects evaluated, we reported spotting in 24 out of 47 (51%), headache in 4 out of 47 (8.5%). The 85% of the women recommended etonogestrel implant to their friends as a contraceptive method, with an approval rating for the implant, expressed a rating from 1 to 10 with the mean that was 7.79, the median 8. CONCLUSIONS: Our results are of interest because they derive from a region of Italy in which the Long acting reversible contraception (LARC) is strongly underused. Etonogestrel implant was a safe and effective, long-acting, reversible hormonal contraception (LARC) and majority of women recommended the etonogestrel implant to their friends as a contraceptive method.

Etonogestrel implant is a safe and effective, long-acting, reversible hormonal contraception (LARC). The majority of women in our study choose the etonogestrel implant for its characteristics; among the main side effects evaluated we reported spotting and headache. The majority of women recommended the etonogestrel implant to their friends as a contraceptive method.

Diagnosis and treatment of unusual multiorgan Echinococcus hydatid cysts.

Background: Echinococcosis is a zoonotic disease caused by Echinococcus granulosus. Usually, the liver is the most affected organ, accounting for approximately 70% to 85% of cases. The lungs represent 20% of the cases. Fewer than 10% are found in other sites, including the bone, brain, spleen, and kidneys. Case presentation: A young man was referred to a local hospital for dull pain in the right flank, fever, and mild cough. Computed tomography showed 2 large cysts: the first involved the left lung and measured 130 × 90.5 × 120 mm, whereas the second cyst was located in the right kidney and measured 130 × 100 × 120 mm. Surgery was performed to remove both lesions in 2 separate surgical sessions. Conclusions: Echinococcosis is a compulsorily notifiable disease. Collaboration between medical doctors from different specializations is necessary. A multidisciplinary approach is important for the correct therapeutic management of the disease. Furthermore, the high possibility of recurrence makes the long-term follow-up mandatory.

PD-L1 immunohistochemical expression in bladder urothelial cancer with SP263, SP142 and 22C3 antibodies: A comparative study.

Programmed death ligand 1 (PD-L1) is currently the only biomarker used for the selection of patients with bladder urothelial cancer for immunotherapy. Several platforms, antibodies and scores are currently available for the evaluation of the expression of PD-L1 in immunohistochemistry (IHC). In this study three different antibodies (SP263, SP142 and 22C3) were compared to establish their performances and concordance rates. Twenty-four consecutive cases of surgically resected urothelial cancers of the bladder were enrolled. All cases were revised, and appropriate tumor areas were selected for IHC. Three commercially available PD-L1 antibodies were tested: 22C3 pharmDx with Dako Autostainer Link 48 (Dako, Carpinteria, Ca), and SP263 and SP142 with the Ventana BenchMark (Ventana Medical Systems, Tucson, AZ) platform. All slides were evaluated by an expert pathologist and both the tumor proportion score (TPS) and the combined positive score (CPS) were determined and compared at two different cut-off levels (≥ 1 and ≥ 10). The SP263 and 22C3 clones produced more positive results with the CPS and TPS scores, respectively. The CPS score identified more positive cases than the TPS score, irrespectively of the clone or the cut-off used; the difference was statistically significant in both the SP263 and SP142 clones with the ≥1 cut-off. No statistically significant differences were found between the clones when the ≥1 cut-off was used, irrespectively of the score. At the contrary, a statistically significant difference (p = 0.024) and a trend to significance (p = 0.082) were respectively found for the TPS and CPS scores, when the SP22C3 and the SP142 clones were compared at a cut-off level of ≥10. The ICC test using CPS was 0.676 and 0.578 for the ≥1 and ≥ 10 cut-offs respectively, and 0.729 and 0.467 respectively for the same cut-offs using TPS. This suggests that the three antibodies under investigation cannot be used interchangeably, especially the 22C3 and SP142 clones which showed statistically significant difference when TPS was tested at a ≥ 10 cut-off.

Assessing the Predictive Power of the Hemoglobin/Red Cell Distribution Width Ratio in Cancer: A Systematic Review and Future Directions.

Background and Objectives: The hemoglobin (Hb)/red cell distribution width (RDW) ratio has emerged as an accessible, repeatable, and inexpensive prognostic factor that may predict survival in cancer patients. The focus of this systematic review is to investigate the prognostic role of the Hb/RDW ratio in cancer and the implications for clinical practice. Materials and Methods: A literature search of PubMed, Scopus, and Web of Science databases was performed by an independent author between 18 March and 30 March 2023 to collect relevant literature that assessed the prognostic value of the Hb/RDW ratio in cancer. Overall survival (OS), progression-free survival (PFS), and the association of these with the Hb/RDW ratio were considered to be the main endpoints. Results: Thirteen retrospective studies, including 3818 cancer patients, were identified and involved in this review. It was observed that, when patients with a high vs. low Hb/RDW ratio were compared, those with a lower Hb/RDW ratio had significantly poorer outcomes (p < 0.05). In lung cancer patients, a one-unit increase in the Hb/RDW ratio reduces mortality by 1.6 times, whilst in esophageal squamous-cell carcinoma patients, a lower Hb/RDW ratio results in a 1.416-times greater risk of mortality. Conclusions: A low Hb/RDW ratio was associated with poor OS and disease progression in patients with cancer. This blood parameter should be considered a standard biomarker in clinical practice for predicting OS and PFS in cancer patients. Future searches will be necessary to determine and standardize the Hb/RDW cut-off value and to assess whether the Hb/RDW ratio is optimal as an independent prognostic factor or if it requires incorporation into risk assessment models for predicting outcomes in cancer patients.

Association of HLA-A*11:01, -A*24:02, and -B*18:01 with Prostate Cancer Risk: A Case-Control Study.

The major histocompatibility complex (MHC) loci, the most polymorphic regions within the human genome, encode protein complexes responsible for antigen presentation and CD4+ and CD8+ cell activation. In prostate cancer (PCa), the second most diagnosed cancer in the male population, MHC loci undergo significant changes in their expression patterns, which affect the ability of the immune system to attack and eliminate malignant cells. The purpose of this study was to explore the genetic diversity of human leukocyte antigen (HLA)-A and HLA-B in patients with PCa and healthy controls (HCs) by performing HLA genotyping using NGS technology. The analysis highlighted statistically significant differences (p < 0.05) in the prevalence of three alleles (A*11:01, A*24:02, and B*18:01). Among the HCs analyzed, 14.89% had A*11:01, 20.21% had A*24:02, and 30.61% had B*18:01; while 5.21% of patients with PCa presented A*11:01, 9.38% presented A*24:02, 18.08% presented B*18:01. Odds ratio (OR) calculations underlined a negative association between the three alleles and the risk of PCa (OR < 1). The results presented in this study suggest a protective role of A*11:01, A*24:02, and B*18:01 in PCa.

A Multigene-Panel Study Identifies Single Nucleotide Polymorphisms Associated with Prostate Cancer Risk.

The immune system plays a critical role in modulating cancer development and progression. Polymorphisms in key genes involved in immune responses are known to affect susceptibility to cancer. Here, we analyzed 35 genes to evaluate the association between variants of genes involved in immune responses and prostate cancer risk. Thirty-five genes were analyzed in 47 patients with prostate cancer and 43 healthy controls using next-generation sequencing. Allelic and genotype frequencies were calculated in both cohorts, and a generalized linear mixed model was applied to test the relationship between prostate cancer risk and nucleotide substitution. Odds ratios were calculated to describe the association between each single nucleotide polymorphism (SNP) and prostate cancer risk. Significant changes in allelic and genotypic distributions were observed for IL4R, IL12RB1, IL12RB2, IL6, TMPRSS2, and ACE2. Furthermore, a generalized linear mixed model identified statistically significant associations between prostate cancer risk and SNPs in IL12RB2, IL13, IL17A, IL4R, MAPT, and TFNRS1B. Finally, a statistically significant association was observed between IL2RA and TNFRSF1B and Gleason scores, and between SLC11A1, TNFRSF1B and PSA values. We identified SNPs in inflammation and two prostate cancer-associated genes. Our results provide new insights into the immunogenetic landscape of prostate cancer and the impact that SNPs on immune genes may have on affecting the susceptibility to prostate cancer.

Current Trends in Mucosal Melanomas: An Overview.

Primary mucosal melanomas (MMs) are uncommon tumors originating from melanocytes located in the mucous membranes at various anatomic sites within the body. MM significantly differs from cutaneous melanoma (CM) regarding epidemiology, genetic profile, clinical presentation, and response to therapies. Despite these differences, that have important implications for both disease diagnosis and prognosis, MMs are usually treated in the same way as CM but exhibit a lower response rate to immunotherapy leading to a poorer survival rate. Furthermore, a high inter-patient variability can be observed in relation to therapeutic response. Recently, novel "omics" techniques have evidenced that MM lesions have different genomic, molecular, and metabolic landscapes as compared with CM lesions, thus explaining the heterogeneity of the response. Such specific molecular aspects might be useful to identify new biomarkers aimed at improving the diagnosis and selection of MM patients who could benefit from immunotherapy or targeted therapy. In this review, we have focused on relevant molecular and clinical advancements for the different MM subtypes in order to describe the updated knowledge relating to main diagnostic, clinical, and therapeutic implications as well as to provide hints on likely future directions.

Native tissue repair (NTR) versus transvaginal mesh interventions for the treatment of anterior vaginal prolapse: Systematic review and meta-analysis.

The aim of the present systematic review and meta-analysis was to compare native tissue repair (NTR) against transvaginal mesh augmentation for the repair of anterior vaginal prolapse. A total of 2289 articles were found but only 27 (24.8 %) were included in the review. Guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) were followed to guide the process of the systematic review and meta-analysis. The quality of the observational studies was evaluated according to the Scottish Intercollegiate Guidelines Network, whereas the quality of randomized control trials (RCT) was assessed by the Cochrane risk-of-bias scale. The mesh repair intervention was associated with a higher anatomical cure rate in comparison with NTR repair when the follow-up was ≤24 months [pooled risk difference (95 % CI): -0.18 % (-0.22 %; 0.13 %); p-value: <0.0001; I2: 36.0 %]. Studies reporting anatomical failure had similar findings [pooled risk difference (95 % CI): 0.17 % (0.01 %; 0.33 %); p-value: 0.03; I2: 88.6 %]. No differences in the risk of re-operation were observed between NTR repair and mesh augmentation. Pooled risk differences in the incidence of post-surgical and late complications were higher for the mesh repair intervention [-0.05 % (95 % CI: -0.10 %; 0.00 %) p-value: 0.05; I2: 68.3 %] [-0.05 % (95 % CI: -0.14 %; 0.03 %) p-value: 0.25; I2: 82.0 %]. Women who underwent mesh repair reported greater satisfaction than women who underwent NTR [pooled risk difference (95 % CI): -0.07 % (-0.16 %; 0.02 %); p-value: 0.15; I2: 65.3 %]. In conclusion, mesh repair surgery had higher anatomical cure and satisfaction rates, with no differences in re-operation rate, but had higher post-surgical and late complications in comparison with NTR.

miRNAs as Molecular Biomarkers for Prostate Cancer.

miRNAs are short noncoding RNAs able to regulate specific mRNA stability, thus influencing target gene expression. Disrupted levels of several miRNAs have been associated with prostate cancer (PC), the leading cause of cancer death among men and the fifth leading cause of death worldwide. Herein, we investigated whether miR-145, miR-148, and miR-185 circulating levels in plasma could be used as molecular biomarkers, to allow distinguishing between individuals with benign prostatic hyperplasia, precancerous lesions, and PC. One-hundred and seventy urological clinic patients with suspected PC who underwent prostate biopsy were recruited. Total RNA was isolated from plasma, and TaqMan MicroRNA assays were used to analyze miR-145, miR-185, and miR-148 expression. First, differential miRNA expression among patient groups was evaluated. Then, miRNA levels were combined with clinical assessment outcomes, including results from invasive tests, using multivariate analysis to examine their ability in discriminating among the three patient groups. Our results suggest that miRNA is a promising molecular tool for clinical management of at-risk patients.

Plasma Polyamine Biomarker Panels: Agmatine in Support of Prostate Cancer Diagnosis.

Prostate cancer is the most frequent malignant tumour among males (19%), often clinically silent and of difficult prognosis. Although several studies have highlighted the diagnostic and prognostic role of circulating biomarkers, such as PSA, their measurement does not necessarily allow the detection of the disease. Within this context, many authors suggest that the evaluation of circulating polyamines could represent a valuable tool, although several analytical problems still counteract their clinical practice. In particular, agmatine seems particularly intriguing, being a potential inhibitor of polyamines commonly derived from arginine. The aim of the present work was to evaluate the potential role of agmatine as a suitable biomarker for the identification of different classes of patients with prostate cancer (PC). For this reason, three groups of human patients-benign prostatic hyperplasia (BPH), precancerous lesion (PL), and prostate cancer (PC)-were recruited from a cohort of patients with suspected prostate cancer (n = 170), and obtained plasma was tested using the LC-HRMS method. Statistics on the receiver operating characteristics curve (ROC), and multivariate analysis were used to examine the predictive value of markers for discrimination among the three patient groups. Statistical analysis models revealed good discrimination using polyamine levels to distinguish the three classes of patients. AUC above 0.8, sensitivity ranging from 67% to 89%, specificity ranging from 74% to 89% and accuracy from 73% to 86%, considering the validation set, were achieved. Agmatine plasma levels were measured in PC (39.9 ± 12.06 ng/mL), BPH (77.62 ± 15.05 ng/mL), and PL (53.31 ± 15.27 ng/mL) patients. ROC analysis of the agmatine panel showed an AUC of 0.959 and p ≤ 0.001. These results could represent a future tool able to discriminate patients belonging to the three different clinical groups.

HERV-K and HERV-H Env Proteins Induce a Humoral Response in Prostate Cancer Patients.

A higher expression of human endogenous retroviruses (HERVs) has been associated with several malignancies, including prostate cancer, implying a possible use as a diagnostic or prognostic cancer biomarker. For this reason, we examined the humoral response against different epitopes obtained from the envelope protein of HERV-K (HERV-K env-su19-37, HERV-K env-su109-126), HERV-H (HERV-H env-su229-241, HERV-H env387-399) and HERV-W (HERV-W env-su93-108, HERV-W env-su248-262) in the plasma of patients affected by prostate cancer (PCa), and compared to that of benign prostate hyperplasia (BPH) and a borderline group of patients with atypical small acinar proliferation (ASAP) and prostate intraepithelial neoplasia (PIN) and healthy controls. A significant antibody response was observed against HERV-K env-su109-126 (p = 0.004) and HERV-H env-su229-241 (p < 0.0001) in PCa patients compared to HCs, BPH and borderline cohorts, whilst no significance difference was found in the antibodies against HERV-W env-su93-108 and HERV-W env-su248-262 in patients with PCa. Our results provided further proof of the association between HERV-K and PCa and added new evidence about the possible involvement of HERV-H in PCa pathogenesis, highlighting their possibility of being used as biomarkers of the disease.

The Impact of SARS-CoV-2 Pandemic on Time to Primary, Secondary Resection and Adjuvant Intravesical Therapy in Patients with High-Risk Non-Muscle Invasive Bladder Cancer: A Retrospective Multi-Institutional Cohort Analysis.

BACKGROUND: To investigate the impact of COVID-19 outbreak on the diagnosis and treatment of non-muscle invasive bladder cancer (NMIBC). METHODS: A retrospective analysis was performed using an Italian multi-institutional database of TURBT patients with high-risk urothelial NMIBC between January 2019 and February 2021, followed by Re-TURBT and/or adjuvant intravesical BCG. RESULTS: A total of 2591 patients from 27 institutions with primary TURBT were included. Of these, 1534 (59.2%) and 1056 (40.8%) underwent TURBT before and during the COVID-19 outbreak, respectively. Time between diagnosis and TURBT was significantly longer during the COVID-19 period (65 vs. 52 days, p = 0.002). One thousand and sixty-six patients (41.1%) received Re-TURBT, 604 (56.7%) during the pre-COVID-19. The median time to secondary resection was significantly longer during the COVID-19 period (55 vs. 48 days, p < 0.0001). A total of 977 patients underwent adjuvant intravesical therapy after primary or secondary resection, with a similar distribution across the two groups (n = 453, 86% vs. n = 388, 86.2%). However, the proportion of the patients who underwent maintenance significantly differed (79.5% vs. 60.4%, p < 0.0001). CONCLUSIONS: The COVID-19 pandemic represented an unprecedented challenge to our health system. Our study did not show significant differences in TURBT quality. However, a delay in treatment schedule and disease management was observed. Investigation of the oncological impacts of those differences should be advocated.

High Incidence of Gestational Trophoblastic Disease in a Third-Level University-Hospital, Italy: A Retrospective Cohort Study.

INTRODUCTION: to assess incidence, prognosis and obstetric outcome of patients treated for gestational trophoblastic disease GTD in a twenty-year period. Incidence, prognosis and obstetric outcome of gestational throphoblastic disease. METHODS: retrospective study. RESULTS: Fifty-four cases of GTD: 46 (85.18%) cases of Hydatidiform mole (HM); 8 cases of Persistent Gestational Trophoblastic Neoplasia (GTN) (14.81%): 6/8 cases (75%) GTN not metastatic; 2/8 cases (25%) GTN metastatic. In both cases, the metastases occurred in the lungs. In 3 out of 8 GTN cases (37.5%) a histological picture of choriocarcinoma emerged. The incidence of GTD cases treated from 2000 to 2020 was 1.8 cases per 1000 deliveries and 1.3 cases per 1000 pregnancies. Of the 54 patients, 30 (55.56%) presented showed normal serum hCG levels without the need for chemotherapy. On the other hand, 24 patients (44.44%) developed a persistent trophoblastic disease and underwent adjuvant therapy. The negative prognostic factors that affected the risk of persistence of GTD were: serum hCG levels at diagnosis > 100,000 mUI/ml; characteristic "snow storm" finding at the ultrasound diagnosis; a slow regression of serum hCG levels during follow-up; the persistence of high serum hCG levels (especially if > 1000 mUI/ml one month after suction curettage) that was the main risk factor for resistance to first-line chemotherapy. There were 10 pregnancies in total following treatment. Patients' survival in our study was 100%. DISCUSSION: Although GTD is a rare disease, its incidence was 1.3 cases per 1,000 pregnancies in Sardinia, Italy, higher if compared with mean national and worldwide incidence.

The role of surgery in platinum-resistant ovarian cancer: A call to the scientific community.

In the last decade, a growing attention has been focused on identifying effective therapeutic strategies also in the orphan clinical setting of women with platinum-resistant disease. In this context, secondary cytoreductive surgery (SCS) remains a potential approach only in women with platinum sensitive relapse, but experimental data have been published supporting the role of SCS also in patients with platinum-resistant recurrence. In particular, surgery is emerging as a potential option in specific subgroups of women, such as those patients with low-grade serous histology, or low-volume relapse with disease located in the so-called pharmacological sanctuaries. Furthermore, contrasting evidences have suggested a potential role in this clinical setting of SCS combined with intraperitoneal hyperthermic chemotherapy. In this complex scenario we review here the available evidences regarding the role surgery in ovarian cancer patients with platinum resistant disease, trying also to understand which patients may benefit from this challenging, experimental approach.

A preliminary study procedure for detection of polyamines in plasma samples as a potential diagnostic tool in prostate cancer.

BACKGROUND: Many scientific contributions recognize polyamines as important biomarkers for the diagnosis and treatment of cancer. Several authors have suggested the use of LC/MS instruments as an elective method for their measurement, providing good detection limits and specificity; however, many of these procedures suffer from long chromatographic run times, high detection limits and lengthy and expensive sample pre-treatment steps. METHODS: UHPLC coupled with high-resolution Orbitrap mass spectrometry (UHPLC/Orbitrap) was set up for the identification and separation ofpolyamines, together with some of their metabolites and catabolites, in the plasma of healthy and prostate cancer human patients. Thirteen metabolites were measured in deproteinized plasma samples through a new analytical approach known as the parallel reaction monitoring (PRM) for targeted quantitative analysis. RESULTS: The calibration curves were linear and R2 ranged from 0.9913 to 0.9995 for all analytes. LOQ values are between 0.382 and 25 ng mL-1 and LOD values are between 0.109 and 7.421 ng mL-1. The method shows an accuracy and precision for intra-day and inter-day < 15% RSD and R.E.% for all the QC samples. The matrix effect calculated at different concentration levels did not exceed 15%. CONCLUSIONS: The method developed provides rapid, easy and robust identification and measurement of a wide range of polyamines, and some of their metabolites that can be evaluated as biomarkers to predict the clinical features of prostate cancer patients, avoiding invasive diagnostic procedures.

How Can the COVID-19 Pandemic Lead to Positive Changes in Urology Residency?

The COVID-19 outbreak, in a few weeks, overloaded Italian hospitals, and the majority of medical procedures were postponed. During the pandemic, with hospital reorganization, clinical and learning activities performed by residents suffered a forced remodulation. The objective of this study is to investigate how urology training in Italy has been affected during the COVID-19 era. In this multi-academic study, we compared residents' training during the highest outbreak level with their previous activity. Overall 387 (67.1%) of the 577 Italian Urology residents participated in a 72-h anonymous online survey with 36 items sent via email. The main outcomes were clinical/surgical activities, social distancing, distance learning, and telemedicine. Clinical and learning activity was significantly reduced for the overall group, and after categorizing residents as those working only in COVID hospitals, both "junior" and "senior" residents, and those working in any of three geographical areas created (Italian regions were clustered in three major zones according to the prevalence of COVID-19). A significant decrease in outpatient activity, invasive diagnostic procedures, and endoscopic and major surgeries was reported. Through multivariate analysis, the specific year of residency has been found to be an independent predictor for all response modification. Being in zone 3 and zone 2 and having "senior" resident status were independent predictors associated with a lower reduction of the clinical and learning activity. Working in a COVID hospital and having "senior" resident status were independent predictors associated with higher reduction of the outpatient activity. Working in zone 3 and having "senior" resident status were independent predictors of lower and higher outpatient surgical activity, respectively. Working in a COVID hospital was an independent predictor associated with robotic surgical activity. The majority of residents reported that distance teaching and multidisciplinary virtual meetings are still not used, and 44.8% reported that their relationships with colleagues decreased. The COVID-19 pandemic presents an unprecedented challenge, including changes in the training and education of urology residents. The COVID era can offer an opportunity to balance and implement innovative solutions that can bridge the educational gap and can be part of future urology training.

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.

Serenoa repens + selenium + lycopene vs tadalafil 5 mg for the treatment of lower urinary tract symptoms secondary to benign prostatic obstruction: a Phase IV, non-inferiority, open-label, clinical study (SPRITE study).

OBJECTIVE: To compare in a randomised, open-label, non-inferiority clinical study, the efficacy and tolerability of Serenoa repens (SeR) + selenium (Se) + lycopene (Ly) (SeR-Se-Ly) therapy vs tadalafil 5 mg in men with lower urinary tract symptoms (LUTS). PATIENTS AND METHODS: From May 2015 to January 2017, 427 patients were enrolled in 21 different centres (International Standard Randomised Controlled Trial Number Register [ISRCTN] 73316039). Inclusion criteria included: age between 50 and 80 years, International Prostate Symptom Score (IPSS) ≥12, maximum urinary flow rate (Qmax ) ≤ 15 mL/s, and post-void residual (PVR) <100 mL. Patients were randomised into two groups in a 2:1 ratio: Group A (SeR-Se-Ly, 1 tablet daily for 6 months) and Group B (tadalafil 5 mg, 1 tablet daily for 6 months). The primary endpoint of the study was the non-inferior variation in the IPSS and Qmax in Group A vs Group B after 6 months of treatment. RESULTS: In all, 404 patients completed the full protocol. When comparing both therapies, Group A was statistically not inferior to Group B considering the median change in IPSS (-3.0 vs -3.0; P < 0.01), IPSS quality of life (-2.0 vs -2.0; P < 0.05), and Qmax (2.0 vs 2.0 mL/s; P < 0.01). We found statistically significant differences in the increase of at least 3 points in Qmax (38.2% vs 28.1%; P = 0.04) and of at least 30% of Qmax (39.2% vs 27.3%; P < 0.01) in Group A compared to Group B. The percentage of patients with an increase of at least 3 points in the IPSS and a decrease of at least 25% of the IPSS was not statistically different between the two groups. For adverse events, four patients in Group A (1.44%) and 10 in Group B (7.81%) (P < 0.05) reported side-effects. CONCLUSION: We have shown that treatment with SeR-Se-Ly was not inferior to tadalafil 5 mg for improving IPSS and Qmax in men with LUTS.

Management of female stress urinary incontinence: A care pathway and update.

Stress urinary incontinence (SUI) is a condition characterized by an involuntary loss of urine occurring as result of an increase in intra-abdominal pressure due to effort or exertion or on sneezing or coughing. Estimates of its prevalence in the female population range from 10% to 40%. A literature search of the Medline, Cochrane library, EMBASE, NLH, ClinicalTrials.gov and Google Scholar databases was done up to July 2017, restricted to English-language articles, using terms related to SUI, medical therapy, surgical therapy and treatment options. The search terms included female stress urinary incontinence, mid-urethral sling, tension-free vaginal tape (TVT) and transobturator tape (TOT, TVT-O). Original articles, reviews and meta-analyses were included. Surgical therapy should be considered only after conservative therapies (e.g. an exercise programme or topical estrogens) have failed. Synthetic mid-urethral slings are the gold standard for the surgical treatment of SUI according to the 2016 guidelines of the European Society of Urology (ESU) and the 2017 position statement of the European Urogynaecological Association (EUA). The therapeutic options are numerous but further research into new therapeutic strategies is needed to achieve a better balance between efficacy and adverse events.
