The role of lipidic balance on erectile dysfunction in prostate cancer patients undergoing robotic surgery.

OBJECTIVE: New indices of dyslipidemia, such as the Atherogenic Index of Plasma (AIP) or Castelli Risk Index I and II (CR-I/II), have been tested to predict erectile dysfunction (ED). The aim of this study was to assess the role of these lipidic scores in predicting severe ED and erectile function (EF) worsening in patients who underwent robot-assisted radical prostatectomy (RARP). METHODS: Data from 1249 prostate cancer patients who underwent RARP at our single tertiary academic referral center from September 2021 to April 2023 were reviewed. RARP patients with a complete lipid panel were included in the final analysis. Two independent multivariable logistic regression models (LRMs) were fitted to identify predictors of ED severity and worsening in RARP patients. RESULTS: Among the 357 RARP patients, the median age was 70 (interquartile range [IQR]: 65-74), and the median BMI was 28.4 (IQR: 26-30.4). According to the preoperative IIEF5, 115 (32.2%), 86 (24.5%), 26 (7.3%), and 40 (11.2%) were mild, mild-moderate, moderate, and severe ED patients, respectively. After multivariable LRMs predicting severe ED, only the nerve-sparing (NS) approach (odds ratio [OR]: 0.09) as well as the preoperative IIEF5 score (OR: 0.32) were independent predictors (p < 0.001). After LRMs predicting EF worsening, only preoperative IIEF5 was an independent predictor (OR: 1.42, p < 0.001). CONCLUSION: The power of novel lipidic scores in predicting severe ED and EF worsening in RARP patients was low, and they should not be routinely applied as a screening method in this patient subgroup. Only preoperative IIEF5 and nerve-sparing approaches are relevant in EF prediction after RARP.

Survival of Metastatic Urothelial Carcinoma of Urinary Bladder According to Number and Location of Visceral Metastases.

OBJECTIVE: To test the association between number as well as locations of organ-specific metastatic sites and overall survival (OS) in systhemic-therapy exposed metastatic urothelial carcinoma of urinary bladder (mUCUB) patients. METHODS: Within Surveillance, Epidemiology and End Results database (2010-2020), all systhemic therapy-exposed mUCUB patients were identified. Kaplan-Meier and multivariable Cox regression (CRM) models first addressed OS in patients according to number of metastatic organ-locations: solitary versus 2 versus 3 or more. Subsequently, separate analyses stratified according to location type were completed in patients with solitary metastatic organ-location as well as in patients with 2 metastatic organ-locations. RESULTS: Of 1,310 mUCUB, 1,069 (82%) harbored solitary metastatic organ-location versus 193 (15%) harbored 2 separate metastatic organ-locations versus 48 (3%) harbored 3 or more metastatic organ-locations. Median OS decreased with increasing number of metastatic organ-locations (solitary vs. 2 vs. 3 or more, P < .0001). In multivariable CRM, relative to solitary metastatic organ-location, 2 (HR: 1.57, 95 Confidence interval [CI], 1.33-1.85) as well as 3 or more (HR: 1.69, 95% CI, 1.23-2.31) metastatic organ-locations independently predicted higher overall mortality (OM) (P = .001). In patients with solitary metastatic organ-location, brain metastases independently predicted higher OM (HR 1.67; 95% CI, 1.05-2.67; P = .03) than other locations. In patients with 2 metastatic organ-locations, no differences in OM were recorded according to organ type location. CONCLUSION: In systemic therapy exposed mUCUB, number of metastatic organ-locations (solitary vs. 2 vs. 3 or more), independently predicted increasingly worse prognosis. In patients with solitary metastatic organ-location, brain purported worse prognosis than others.

Unmarried Status Effect on Stage at Presentation and Treatment Patterns in Non-Metastatic Upper Tract Urothelial Carcinoma Patients.

BACKGROUND: Unmarried status has been associated with higher proportions of locally advanced stage and lower treatment dose intensification rates in several urological and non-urological malignancies. However, no previous investigators focused on the association between unmarried status and advanced stage (T3-4N0-2) at presentation and lower nephroureterectomy (RNU) and systemic therapy (ST) rates in non-metastatic upper tract urothelial carcinoma (UTUC) patients. METHODS: Using the Surveillance, Epidemiology, and End Results (SEER) database 2000-2020, all non-metastatic UTUC patients were identified. Multivariable logistic regression models (LRMs) tested for differences in stage at presentation and treatment (RNU and ST) according to marital status (married vs unmarried), in a sex-specific fashion. RESULTS: Of all 8544 non-metastatic UTUC patients, 4748 (56%) were male vs 3190 (44%) were female. Of all 4748 male UTUC patients, 1191 (25%) were unmarried. Of all 3190 female UTUC patients, 1608 (50%) were unmarried. In multivariable LRMs predicting RNU, unmarried status was an independent predictor of lower RNU rates in male (Odds Ratio [OR]: 0.56; P < .001), but not in female (OR: 0.81; P = .1) non-metastatic UTUC patients. In multivariable LRMs predicting ST exposure, unmarried status was an independent predictor of lower ST rates in both male (OR:0.73; P = .03) and female (OR:0.64; P < .001) UTUC patients. In multivariable LRMs predicting locally advanced stage (T3-4N0-2), unmarried status was not associated with an increased risk of locally advanced stage at presentation in either male (OR: 0.95; P = .5) or female (OR: 0.99; P = .9) UTUC patients. CONCLUSIONS: Unmarried male UTUC patients appear at risk of less being able to access RNU, relative to their married counterparts. Moreover, unmarried UTUC patients appear to less benefit from ST, regardless of sex. Conversely, unmarried status was not associated with an increased risk of locally advanced stage at presentation in either male or female UTUC patients.

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.

Telemedicine and social media: A contemporary analysis of the most shared content by internet users.

OBJECTIVE: To evaluate the telemedicine information published on the most popular social media platforms, during the second year of the COVID-19 pandemic. METHODS: We queried the BuzzSumo tool to identify related telemedicine article links that were shared most on social media, from February 2021 to February 2022. The PEMAT-P was used for the quality assessment of the most shared links. RESULTS: 125 links were eligible for the analysis. Facebook was the most used social media platform for sharing articles (median engagement: 1000). Most of the articles were published by magazines (n = 82, 65.6%) and the main topic addressed was general information (n = 49, 39.2%). In the subgroup analyses of the 34 most shared articles, Facebook was the most used social media platform (median engagement:1950), most of the articles were published by magazines (n = 24, 70.6%), whereas the main topic addressed was the prescription of the abortion pill (n = 9, 26.5%). According to the PEMAT-P tool, the median understandability and actionability score was 63.8 and 20%, respectively. CONCLUSIONS: The interest in telemedicine has increased all over the world, as evidenced by the high engagement in social media articles, recorded during the last year. However, the access to digital health services is still limited, the information provided is often not verified by an official entity and unable to fill the digital divide exacerbated by COVID 19 pandemic crisis. Hence, health policy should be developed or modified to ensure a more egalitarian Internet access for all citizens. Official medical institutions should standardize telemedicine regulation and online content to reduce the widespread of misleading information.

Long-Term Oncological Outcomes after Nerve-Sparing Robot-Assisted Radical Prostatectomy for High-Risk Localized Prostate Cancer: A Single-Center, Two-Arm Prospective Study.

AIMS: To compare the oncological outcomes of patients with high-risk localized prostate cancer undergoing nerve-sparing and non-nerve-sparing robot-assisted radical prostatectomy (RARP). METHODS: Between November 2002 and December 2018, we prospectively recorded the data of patients undergoing RARP for high-risk localized prostate cancer (PCa) at our tertiary referral center. NSS (nerve-sparing surgery) was carefully offered on the basis of the preoperative clinical characteristics of the patients and an intraoperative assessment. The patients were stratified into two groups: nerve-sparing and non-nerve-sparing groups (yes/no). Radical prostatectomies were performed by 10 surgeons with a robot-assisted technique using a daVinci® surgical system. The primary oncological outcome evaluated was biochemical recurrence (BCR). The secondary oncological outcomes assessed were positive surgical margins (PSMs) and cancer-specific survival (CSS). RESULTS: A total of 779 patients were included in the study: 429 (55.1%) underwent NSS while 350 (44.9%) underwent non-NSS. After a mean (±SD) follow-up of 192 (±14) months, 328 (42.1%) patients developed BCR; no significant difference was found between the NSS and non-NSS groups (156 vs. 172; p = 0.09). Both our univariable and multivariable analyses found that the nerve-sparing approach was not a predictor of BCR (p > 0.05). Kaplan-Mayer survival curves for BCR showed no significant difference among the non-NSS, unilateral NSS, and bilateral NSS groups (log rank test = 0.6). PSMs were reported after RARPs for 254 (32.6%) patients, with no significant difference between the NSS and non-NSS group (143 vs. 111; p = 0.5). In the subgroup of 15 patients who died during the follow-up period, mean (±SD) CSS was 70.5 (±26.1) months, with no significant difference between the NSS and non-NSS groups (mean CSS: 70.3 vs. 70.7 months). CONCLUSIONS: NSS does not appear to negatively impact the oncological outcomes of patients with high-risk PCa. Randomized clinical trials are needed to confirm our promising findings.

Other-cause mortality in incidental prostate cancer.

BACKGROUND: In incidental prostate cancer (IPCa), elevated other-cause mortality (OCM) may obviate the need for active treatment. We tested OCM rates in IPCa according to treatment type and cancer grade and we hypothesized that OCM is significantly higher in not-actively-treated patients. METHODS: Within the Surveillance, Epidemiology, and End Results database (2004-2015), IPCa patients were identified. Smoothed cumulative incidence plots as well as multivariable competing risks regression models were fitted to address OCM after adjustment for cancer-specific mortality (CSM). RESULTS: Of 5121 IPCa patients, 3655 (71%) were not-actively-treated while 1466 (29%) were actively-treated. Incidental PCa not-actively-treated patients were older and exhibited higher proportion of Gleason sum (GS) 6 and clinical T1a stage. In smoothed cumulative incidence plots, 5-year OCM was 20% for not-actively-treated versus 8% for actively-treated patients. Conversely, 5-year CSM was 5% for not-actively-treated versus 4% for actively-treated patients. No active treatment was associated with 1.4-fold higher OCM, even after adjustment for age, cancer characteristics, and CSM. According to GS, OCM reached 16%, 27%, and 35% in GS 6, 7, and 8-10 not-actively-treated IPCa patients, respectively and exceeded CSM recorded for the same three groups (2%, 6%, and 28%, respectively). CONCLUSION: Our results quantified OCM rates, confirming that in not-actively-treated IPCa patients OCM is indeed significantly higher than in their actively-treated counterparts (HR: 1.4). These observations validate the use of no active treatment in IPCa patients, in whom OCM greatly surpasses CSM (20% vs. 5%).

Carbapenem-Resistant Enterobacteriaceae in Urinary Tract Infections: From Biological Insights to Emerging Therapeutic Alternatives.

Urinary tract infections (UTIs) are the second most frequent type of infection observed in clinical practice. Gram-negative Enterobacteriaceae are common pathogens in UTIs. Excessive antibiotic use in humans and animals, poor infection control, and increased global travel have accelerated the spread of multidrug-resistant strains (MDR). Carbapenem antibiotics are commonly considered the last line of defense against MDR Gram-negative bacteria; however, their efficacy is now threatened by the increasing prevalence of carbapenem-resistant Enterobacteriaceae (CRE). This comprehensive review aims to explore the biological mechanisms underlying carbapenem resistance and to present a focus on therapeutic alternatives currently available for complicated UTIs (cUTIs). A comprehensive bibliographic search was conducted on the PubMed/MEDLINE, Scopus, and Web of Science databases in December 2023. The best evidence on the topic was selected, described, and discussed. Analyzed with particular interest were the clinical trials pivotal to the introduction of new pharmacological treatments in the management of complicated cUTIs. Additional suitable articles were collected by manually cross-referencing the bibliography of previously selected papers. This overview provides a current and comprehensive examination of the treatment options available for CRE infections, offering a valuable resource for understanding this constantly evolving public health challenge.

Unmarried status effect on stage at presentation and treatment patterns in primary urethral carcinoma patients.

BACKGROUND: Unmarried status has been associated with advanced stage at presentation and lower treatment dose intensification rates in several urological and non-urological malignancies. However, no previous investigators focused of the association of unmarried status with locally advanced stage (T3-4N0-2) at presentation and lower bi-/trimodal therapy rates in primary urethral carcinoma (PUC) patients. To address these knowledge gaps, we relied on the Surveillance, Epidemiology, and End Results (SEER) database. METHODS: Within the SEER database 2000 to 2020, all non-metastatic PUC patients were identified. Logistic regression models (LRMs) tested for differences in stage at presentation and treatment modality in the overall cohort and then in a sex-specific fashion, according to marital status (married vs unmarried). RESULTS: Of all 1,430 non-metastatic PUC patients, 1,004 (70%) were male vs 426 (30%) were female. Of 1,004 male PUC patients, 272 (27%) were unmarried. Of all 426 female PUC patients, 239 (56%) were unmarried. In multivariable LRMs predicting T3-4N0-2, unmarried status was independently associated with an increased risk of locally advanced stage at presentation in the overall cohort (odds ratio [OR]:1.31; P = 0.03) and in female patients (OR:1.62; P = 0.02), but not in male PUC patients (P = 0.6). In multivariable LRMs predicting bi-/trimodal therapy, unmarried status was an independent predictor of lower bi-/trimodal therapy rates in the overall cohort (OR:0.73; P = 0.02) and in male patients (OR:0.60; P = 0.007), but not in female PUC patients (P = 0.6). CONCLUSIONS: Unmarried female PUC patients more likely harbored locally advanced stage at presentation. Conversely, unmarried male PUC patients are less likely to benefit from bi-/trimodal therapy.

Regional differences in upper tract urothelial carcinoma patients across the United States.

BACKGROUND: It is unknown whether regional differences in patient, tumor, and treatment characteristics of upper tract urothelial carcinoma (UTUC) patients exist and may potentially result in regional overall mortality (OM) differences. We tested for inter-regional differences, according to Surveillance, Epidemiology, and End Results (SEER) registries. METHODS: Using SEER database 2000 to 2016, patient (age, sex, race/ethnicity), tumor (location, grade) and treatment (nephroureterectomy, systemic therapy [ST]) characteristics of UTUC patients of all-stages were tabulated and graphically depicted in a stage-specific fashion (T1-2N0M0 vs. T3-4N0M0 vs. TanyN1-2M0/TanyNanyM1). Multivariable Cox regression (MCR) models tested for inter-regional differences in OM. RESULTS: Regarding T1-2N0M0 patients, statistically significant differences existed for race/ethnicity (Caucasian 71 vs. 98%), location (renal pelvis: 55 vs. 67%), grade (high 60 vs. 83%) and ST (5.5 vs. 13.9%). In MCR models, registries 3 (Hazard ratio [HR]:1.39; P < 0.001) and 4 (HR:1.31; P = 0.01) independently predicted higher OM and Registry 8 (HR:0.64; P = 0.001) lower OM. Regarding T3-4N0M0 patients, statistically significant differences existed for race/ethnicity (Caucasian 70 vs. 98%), location (renal pelvis: 67 vs. 76%), grade (high 84 vs. 94%) and ST (18.7 vs. 29.5%). In MCR models, registries 3 (HR:1.42; P < 0.001) and 4 (HR:1.31; P = 0.009) independently predicted higher OM. Regarding TanyN1-2M0/TanyNanyM1 patients, statistically significant differences existed for location (renal pelvis: 63 vs. 82%), grade (high 92 vs. 98%) and ST (53.4 vs. 58.8%). In MCR models, Registry 3 (HR:1.37; P = 0.004) independently predicted higher OM and Registry 2, (HR:0.78; P = 0.02) lower OM. CONCLUSIONS: Inter-regional differences were recorded in patients, tumor, and treatment characteristics. Even after adjustment for these characteristics, OM differences persisted which may be indicative of regional differences in quality of care or expertise in UTUC management.

Long-term outcomes of extracorporeal shock wave therapy for acute Peyronie's disease: a 10-year retrospective analysis.

The aim of this paper was to describe the long-term outcomes of extracorporeal shock wave therapy (ESWT) in patients with acute Peyronie'disease (PD). An observational retrospective study was conducted in men with acute PD who underwent ESWT between 2009-2013 at a single institution. ESWT protocol consisted of 1 session (3000 shock waves, 0.10-0.25 mJ/mm^2, 4-6 Hz) per week for 4 weeks. Penile pain was chosen as the primary outcome. Penile curvature angle, erectile function, and satisfaction with ESWT were selected as secondary long-term outcomes. A total of 194 patients were included. The mean follow-up duration after ESWT was 125.6 months. Mean penile curvature worsened significantly at 3 months (18.3 vs. 21.5 degrees; p = 0.023) and 12 months (21.5 vs. 28.6 degrees; p = 0.001) and stabilized over the long-term (28.6 vs. 28.8 degrees; p = 0.335). Mean penile pain improved significantly at 3 months (6.5 vs. 3.1 points; p < 0.001) and 12 months (3.1 vs. 1.0 points; p = 0.001), remaining stable over time (1.0 vs. 1.0 points; p = 0.074). The mean five-item version of the International Index of Erectile Function (IIEF-5) increased significantly at 3 months (14.5 vs. 17.9 points; p = 0.001), remaining stable at 12 months (17.9 vs. 18.5 points; p = 0.082), and deteriorating in the long-term (18.5 vs. 15.8 points; p = 0.003). A high satisfaction rate with ESWT was recorded at 3 months (92.3%), remaining similar at 12 months (91.2%) and over the long-term (90.2%). No new acute phase and low rate of PD surgery (4.1%) were recorded in the long-term analysis. In patients with acute PD, ESWT seems to be associated with early and persistent relief of penile pain, transient improvement in erectile function, no significant effect on penile curvature, and a high rate of patient satisfaction constant over time.

A mobile health application for prostate cancer antigen dosage: is it time to say goodbye to classic screening methods?

OBJECTIVE: To evaluate the quality of apps for prostate cancer antigen (PSA) dosage, available for downloading on the iOS and Android platforms, discussing the potential role of mobile health applications (MHAs) in update the screening protocol. METHODS: An observational cross-sectional descriptive study of all smartphone apps for PSA dosage was performed through the most used platforms (iOS and Android). On 10 February 2023, a total of 457 apps were found according to the search criteria. Mobile Application Rating Scale (MARS) was adopted to assess apps' quality. Then, MARS items were analyzed through descriptive statistics and bivariate correlations between study variables with Pearson's coefficient. RESULTS: Of all samples, 24 MHAs were included in the final analysis: 12% (n = 3) from the iTunes App Store and 88% (n = 21) from the Google Play Store. According to the MARS quality assessment, the mean values 2.61, 2.94, 3.11, 2.97, 2.94, and 2.63 were measured for the engagement, functionality, aesthetics, information, overall mean score, and subjective quality, respectively. CONCLUSION: The MHAs for PSA were under the acceptability threshold and future improvements are required. Moreover, MHAs appropriately developed could play an active role in PSA screening campaign and adherence of follow-up regimens. Finally, the virtual instrument could both reduce the social divide of access to care for patients in rural areas and improve PCA detection, speeding up the active treatment.

The Role of miRNA in Testicular Cancer: Current Insights and Future Perspectives.

Background and Objectives: Despite advancements in the diagnosis and treatment of testicular germ cell tumours (TGTCs), challenges persist in identifying reliable biomarkers for early detection and precise disease management. This narrative review addresses the role of microRNAs (miRNAs) as potential diagnostic tools and therapeutic targets in the treatment of TGCTs. Materials and Methods: Three databases (PubMed®, Web of Science™, and Scopus®) were queried for studies investigating the utility of miRNA as diagnostic tools, assessing their prognostic significance, and evaluating their potential to guide TGCT treatment. Different combinations of the following keywords were used, according to a free-text protocol: "miRNA", "non-coding RNA", "small RNA", "Testicular Cancer", "seminomatous testicular germ cell", "non-seminomatous testicular germ cell". Results: The potential of miRNAs as possible biomarkers for a non-invasive diagnosis of TGCT is appealing. Their integration into the diagnostic pathway for TGCT patients holds the potential to enhance the discriminative power of conventional serum tumour markers (STMs) and could expedite early diagnosis, given that miRNA overexpression was observed in 50% of GCNIS cases. Among miRNAs, miR-371a-3p stands out with the most promising evidence, suggesting its relevance in the primary diagnosis of TGCT, particularly when conventional STMs offer limited value. Indeed, it demonstrated high specificity (90-99%) and sensitivity (84-89%), with good positive predictive value (97.2%) and negative predictive value (82.7%). Furthermore, a direct relationship between miRNA concentration, disease burden, and treatment response exists, regardless of disease stages. The initial evidence of miRNA decrease in response to surgical treatment and systemic chemotherapy has been further supported by more recent results suggesting the potential utility of this tool not only in evaluating treatment response but also in monitoring residual disease and predicting disease relapse. Conclusions: MiRNAs could represent a reliable tool for accurate diagnosis and disease monitoring in the treatment of TGCT, providing more precise tools for early detection and treatment stratification. Nevertheless, well-designed clinical trials and comprehensive long-term data are needed to ensure their translation into effective clinical tools.

The spreading information of YouTube videos on Phosphodiesterase 5 inhibitors: a worrisome picture from one of the most consulted internet source.

Several previous studies on YouTubeTM information on medical topics have already been published. The current study aimed to evaluate the quality information of YouTubeTM videos on Phosphodiesterase 5 inhibitors (PDE5-is). A systematic search on YouTube™ was conducted using 30 keyword combinations. For each keyword's combination, the first 50 videos were recorded. The quality of videos on YouTube™ was assessed with Patient Education Materials Assessment Tool for audio-visual content (PEMAT A/V), DISCERN score and a specified created Misinformation tool. According to the selection criteria, 229 YouTube™ videos were suitable for the analyses. Videos were stratified according to the five main identified topics: sildenafil [n = 98; 42.79%] vs tadalafil [n = 50; 21.83%] vs vardenafil [n = 44;19.21%] vs avanafil [n = 17; 7.42%] vs PDE5-is in general [n = 20; 8.73%]. The median overall PEMAT A/V Understandability score and Actionability score were 55% (interquartile range [IQR]: 42-75) and 0% (IQR = 0-67), respectively. Specifically, according to our stratification, YouTube Videos on avanafil reached higher values of both Understandability and Actionability (72.7% and 66.7, respectively) in contrast to other categories. According to DISCERN tool, the total overall median score was 29.5 (IQR = 18-41). According to Misinformation scale, the item 1 ('sexual stimulation') harboured an overall median score of 2 (IQR = 1-2); the item 2 ('side effects') an overall median score of 2 (IQR = 1-3); the item 3 ('treatment choices') an overall median score of 1 (IQR = 1-2); the item 4 ('contraindications') an overall median score of 2 (IQR = 1-2). YouTube™ is a fast and open-access source for mass information. The overall quality of the PDE5-is contents provided is sadly unsatisfactory. Nowadays, YouTube™ cannot be recommended as a reliable source of information on PDE5-is.

Demographics, Clinical Characteristics and Survival Outcomes of Primary Urinary Tract Malignant Melanoma Patients: A Population-Based Analysis.

All primary urinary tract malignant melanoma (ureter vs. bladder vs. urethra) patients were identified from within the Surveillance, Epidemiology, and End Results (SEER) database 2000-2020. Kaplan-Maier plots depicted the overall survival (OS) rates. Univariable and multivariable Cox regression (MCR) models were fitted to test the differences in overall mortality (OM). In the overall cohort (n = 74), the median OS was 22 months. No statistically significant or clinically meaningful differences were recorded according to sex (female vs. male; p = 0.9) and treatment of the primary (endoscopic vs. surgical; p = 0.6). Conversely, clinically meaningful but not statistically significant (p ≥ 0.05) differences were recorded according to the patient's age at diagnosis (≤80 vs. ≥80 years old; p = 0.2), marital status (married 26 vs. unmarried 16 months; p = 0.2), and SEER stage (localized 31 vs. regional 14 months; p = 0.4), and the type of systemic therapy (exposed 31 vs. not exposed 20 months; p = 0.06). Finally, in univariable and MCR analyses, after adjustment for the SEER stage and type of systemic therapy, tumor origin within the bladder was associated with a three-fold higher OM (Hazard ratio: 3.00; p = 0.004), compared to tumor origin within the urethra. In conclusion, primary urinary tract malignant melanoma patients have poor survival. Specifically, tumor origin within the bladder independently predicted a higher OM, even after adjustment for the SEER stage and systemic therapy status.

D-Mannose Plus Saccharomyces boulardii to Prevent Urinary Tract Infections and Discomfort after Cystoscopy: A Single-Center Prospective Randomized Pilot Study.

Background and Objectives: Patients undergoing cystoscopy can experience discomfort or pain during the procedure. In some cases, a urinary tract infection (UTI) with storage lower urinary tract symptoms (LUTS) may occur in the days following the procedure. This study aimed to assess the efficacy of D-mannose plus Saccharomyces boulardii in the prevention of UTIs and discomfort in patients undergoing cystoscopy. Materials and Methods: A single-center prospective randomized pilot study was conducted between April 2019 and June 2020. Patients undergoing cystoscopy for suspected bladder cancer (BCa) or in the follow-up for BCa were enrolled. Patients were randomized into two groups: D-Mannose plus Saccharomyces boulardii (Group A) vs. no treatment (Group B). A urine culture was prescribed regardless of symptoms 7 days before and 7 days after cystoscopy. The International Prostatic Symptoms Score (IPSS), 0-10 numeric rating scale (NRS) for local pain/discomfort, and EORTC Core Quality of Life questionnaire (EORTC QLQ-C30) were administered before cystoscopy and 7 days after. Results: A total of 32 patients (16 per group) were enrolled. No urine culture was positive in Group A 7 days after cystoscopy, while 3 patients (18.8%) in Group B had a positive control urine culture (p = 0.044). All patients with positive control urine culture reported the onset or worsening of urinary symptoms, excluding the diagnosis of asymptomatic bacteriuria. At 7 days after cystoscopy, the median IPSS of Group A was significantly lower than that of Group B (10.5 vs. 16.5 points; p = 0.021), and at 7 days, the median NRS for local discomfort/pain of Group A was significantly lower than that for Group B (1.5 vs. 4.0 points; p = 0.012). No statistically significant difference (p > 0.05) in the median IPSS-QoL and EORTC QLQ-C30 was found between groups. Conclusions: D-Mannose plus Saccharomyces boulardii administered after cystoscopy seem to significantly reduce the incidence of UTI, the severity of LUTS, and the intensity of local discomfort.

Sexual dysfunctions of rheumatological patients are a neglected issue: Results from a national survey of Italian Society of Rheumatology.

INTRODUCTION: Sexual dysfunctions (SD) are frequently encountered in patients with rheumatologic diseases. In this scenario, a multidisciplinary approach to rheumatologic diseases is often mandatory. The aim of this survey was to assess whether Italian rheumatologists routinely explore sexual health of their patients, their knowledge on the topic, and the barriers to discussing SD in clinical practice. METHODS: A 32-items anonymous questionnaire was mailed to members of the Italian Society of Rheumatology (rheumatologists and residents in rheumatology training) in February 2023. The questionnaire aimed to determine attitudes, knowledge, and practice patterns regarding the discussion of SD with rheumatologic patients. A descriptive analysis of responses was performed. RESULTS: A total of 162 responses were received. Overall, 50.0% of respondents occasionally asked patients about SD related to their rheumatologic pathologies, while 37.1% never did so. Respondents declared that patients occasionally (82.3%) or never (16.1%) reported SD related to rheumatologic diseases. The main barriers to discussing sexual health were lack of time during medical examination (46.6%), patients' discomfort (44.8%), and lack of knowledge/experience (39.7%). Overall, 41.9% and 33.9% of respondents respectively totally and partially agreed that rheumatologists should routinely investigate patients' sexual health. Most of the respondents (79.0%) thought that discussing sexual health problems could help patients cope with their rheumatologic diseases. Of all respondents, 74.2% felt the need to broaden their personal knowledge about SD. Finally, 45.9% and 34.4% of respondents respectively partially and totally agreed that training courses for rheumatologists could be helpful in the management of sexual health in rheumatological patients. CONCLUSIONS: SD was not routinely discussed in rheumatology practice, still remaining a neglected issue. The most frequent explanations for the lack of attention toward SD were lack of time, patients' discomfort, and lack of knowledge/experience. Most of the respondents expressed the possible usefulness of attending SD courses to improve knowledge about these conditions.

Recreation use of phosphodiesterase type 5 inhibitors, the other side of erectile dysfunction.

To the Editor, In 1998 Sildenafil was approved by the Food and Drug Administration as first line therapy for erectile dysfunction.

Telemedicine and YouTube™: Video quality analysis before and after COVID-19 pandemic.

OBJECTIVE: To assess the quality content of YouTubeTM videos on telemedicine during COVID-19 pandemic. MATERIALS AND METHODS: First, the frequency of worldwide YouTube™ and Google™ searches for telemedicine was analyzed. Second, we queried YouTube™ with telemedicine-related terms. Third, the Patient Education Materials Assessment Tool for Audiovisual Materials (PEMAT A/V), the Global Quality Score (GQS), and the Misinformation tool were used for the quality assessment. RESULTS: According to selection criteria, 129 videos were collected for the analysis. From January 2018 to January 2022, the peak relative interest on YouTube™ and Google™ occurred in March 2020. Of all, 27.1 and 72.9% were uploaded before (Jan 2018-Feb 2020) and after (Mar 2020-Mar 2022) the COVID-19 outbreak, respectively. According to the PEMAT A/V, the overall median understandability and actionability was 50.0% (33.3 [IQR 0-66.7] vs 50.0 [27.1-75], p = 0.2) and 66.7% (63.6 [IQR 50.0-75.7] vs 67.9 [50.0-79.2],p = 0.6), respectively. According to GQS, 3.9%, 17.8%, 24.0%, 26.4% and 27.9% were classified as excellent, good, medium, generally poor, and poor-quality videos, respectively. The highest rate of poor-quality videos was recorded in videos uploaded before COVID-19 pandemic (37.1 vs 24.5%). According to overall misinformation score, a higher score was recorded for the videos uploaded after COVID-19 pandemic (1.8 [IQR 1.4-2.3] vs 2.2 [1.8-2.8], p = 0.01). CONCLUSIONS: The interest in telemedicine showed a significant peak when the COVID-19 pandemic was declared. However, the contents provided on YouTubeTM were not informative enough. In the future, official medical institutions should standardize telemedicine regulation and online content to reduce the widespread of misleading information.
