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.

Contemporary survival in metastatic bladder cancer patients: A population-based study.

The overall survival (OS) improvement after the advent of several novel systemic therapies, designed for treatment of metastatic urothelial carcinoma of the urinary bladder (mUCUB), is not conclusively studied in either contemporary UCUB patients and/or non-UCUB patients. Within the Surveillance, Epidemiology, and End Results database, contemporary (2017-2020) and historical (2000-2016) systemic therapy-exposed metastatic UCUB and, subsequently, non-UCUB patients were identified. Separate Kaplan-Meier and multivariable Cox regression (CRM) analyses first addressed OS in mUCUB and, subsequently, in metastatic non-UCUB (mn-UCUB). Of 3443 systemic therapy-exposed patients, 2725 (79%) harbored mUCUB versus 709 (21%) harbored mn-UCUB. Of 2725 mUCUB patients, 582 (21%) were contemporary (2017-2020) versus 2143 (79%) were historical (2000-2016). In mUCUB, median OS was 11 months in contemporary versus 8 months in historical patients (Δ = 3 months; p < .0001). After multivariable CRM, contemporary membership status (2017-2020) independently predicted lower overall mortality (OM; hazard ratio [HR] = 0.68, 95% confidence interval [CI] = 0.60-0.76; p < .001). Of 709 mn-UCUB patients, 167 (24%) were contemporary (2017-2020) and 542 (76%) were historical (2000-2016). In mn-UCUB, median OS was 8 months in contemporary versus 7 months in historical patients (Δ = 1 month; p = .034). After multivariable CRM, contemporary membership status (2017-2020) was associated with HR of 0.81 (95% CI = 0.66-1.01; p = .06). In conclusion, contemporary systemic therapy-exposed metastatic patients exhibited better OS in UCUB. However, the magnitude of survival benefit was threefold higher in mUCUB and approximated the survival benefits recorded in prospective randomized trials of novel systemic therapies.

Temporal Trends and Cancer-Specific Mortality in Nonmetastatic Muscle-Invasive Urothelial Carcinoma of the Urinary Bladder Treated With Trimodal Therapy.

INTRODUCTION: Trimodal therapy (TMT) is guideline-recommended for the management of organ confined urothelial carcinoma of urinary bladder (UCUB). However, temporal trends in TMT use and cancer-specific mortality free-survival (CSM-FS) between historical TMT versus contemporary TMT have not been assessed. We addressed this knowledge gap. MATERIAL AND METHODS: Within the Surveillance, Epidemiology, and End Results database (2004-2020), we identified nonmetastatic UCUB patients with cT2-T4aN0-N2 treated with TMT, defined as the combination of transurethral resection of bladder tumor, chemotherapy and radiotherapy. Temporal trends described TMT use over time. Subsequently, patients were divided between historical (2004-2012) versus contemporary (2013-2020) cohorts. Survival analyses consisting of Kaplan-Meier plots and multivariable Cox regression (MCR) models addressed CSM-FS. Separate analyses addressed patients with organ confined (OC: cT2N0M0) versus nonorgan confined (NOC: cT3-4a and/or cN1-2) clinical stages. RESULTS: Of 4,097 assessable UCUB TMT patients, 1744 (43%) were treated in the historical period (2004-2012) versus 2353 (58%) in the contemporary period (2013-2020). TMT use increased over time in OC patients (EAPC:+3.4%, P < .001), as well as in NOC (EAPC:+2.7%, P < .001). In OC stage, median CSM-FS was 55.3% in historical versus 49.0% in contemporary patients (HR:0.75, P < .001). Similarly, in NOC stage, 5-year median CSM-FS was 43.0% in historical versus 32.8% in contemporary patients (HR:0.78, P = .01). CONCLUSION: TMT rates have increased over time in both OC and NOC patients. Contemporary TMT patients benefit of better cancer-specific survival. Interestingly, this benefit applies equally to OC and NOC TMT-treated patients.

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.

Validation of the Quality Analysis of Medical Artificial Intelligence (QAMAI) tool: a new tool to assess the quality of health information provided by AI platforms.

BACKGROUND: The widespread diffusion of Artificial Intelligence (AI) platforms is revolutionizing how health-related information is disseminated, thereby highlighting the need for tools to evaluate the quality of such information. This study aimed to propose and validate the Quality Assessment of Medical Artificial Intelligence (QAMAI), a tool specifically designed to assess the quality of health information provided by AI platforms. METHODS: The QAMAI tool has been developed by a panel of experts following guidelines for the development of new questionnaires. A total of 30 responses from ChatGPT4, addressing patient queries, theoretical questions, and clinical head and neck surgery scenarios were assessed by 27 reviewers from 25 academic centers worldwide. Construct validity, internal consistency, inter-rater and test-retest reliability were assessed to validate the tool. RESULTS: The validation was conducted on the basis of 792 assessments for the 30 responses given by ChatGPT4. The results of the exploratory factor analysis revealed a unidimensional structure of the QAMAI with a single factor comprising all the items that explained 51.1% of the variance with factor loadings ranging from 0.449 to 0.856. Overall internal consistency was high (Cronbach's alpha = 0.837). The Interclass Correlation Coefficient was 0.983 (95% CI 0.973-0.991; F (29,542) = 68.3; p < 0.001), indicating excellent reliability. Test-retest reliability analysis revealed a moderate-to-strong correlation with a Pearson's coefficient of 0.876 (95% CI 0.859-0.891; p < 0.001). CONCLUSIONS: The QAMAI tool demonstrated significant reliability and validity in assessing the quality of health information provided by AI platforms. Such a tool might become particularly important/useful for physicians as patients increasingly seek medical information on AI platforms.

Perioperative complications and in-hospital mortality in radical cystectomy patients with heart-valve replacement.

PURPOSE: To assess in-hospital mortality and complication rates after radical cystectomy (RC) in patients with history of heart-valve replacement. MATERIALS AND METHODS: Using the National Inpatient Sample (2000-2019), non-metastatic bladder cancer patients undergoing RC were stratified according to history of heart-valve replacement. Regression models (RM) predicted hospital outcomes. RESULTS: Of 25,535 RC patients, 250 (1.0%) harbored history of heart-valve replacement. Heart-valve replacement patients were older (median 74 vs. 70 years), more frequently male (87.2 vs. 80.6%), and more frequently had Charlson comorbidity index ≥3 (26.8 vs. 18.9%). In RC patients with history of heart-valve replacement vs. others, 62 vs. 2634 (24.8 vs. 10.4%) experienced cardiac complications, 28 vs. 3092 (11.2 vs. 12.2%) intraoperative complications, 11 vs. 1046 (4.4 vs. 4.1%) infections, <11 vs. 594 (<4.4 vs. 2.3%) perioperative bleeding, <11 vs. 699 (<4.4 vs. 2.8%) vascular complications, 74 vs. 6225 (29.6 vs. 24.7%) received blood transfusions, 37 vs. 3054 (14.8 vs. 12.1%) critical care therapy (CCT), and in-hospital mortality was recorded in <11 vs. 463 (<4.4 vs. 1.8%) patients. In multivariable RM, history of heart-valve replacement independently predicted cardiac complications (odds ratio 2.20, 95% confidence interval 1.62-2.99; p < 0.001). Conversely, no statically significant association was recorded between history of heart-valve replacement and length of stay, estimated hospital cost, intraoperative complications, perioperative bleeding, vascular complications, infections, blood transfusions, CCT use, and in-hospital mortality. CONCLUSIONS: Radical cystectomy patients with history of heart-valve replacement exhibited a 2.2-fold higher risk of cardiac complications, but no other complications, including no significantly higher in-hospital mortality.

Non-Surgical Bladder-Sparing Multimodal Management in Organ-Confined Urothelial Carcinoma of the Urinary Bladder: A Population-Based Analysis.

BACKGROUND: Trimodal therapy is considered the most validated bladder-sparing treatment in patients with organ-confined urothelial carcinoma of the urinary bladder (T2N0M0). However, scarce evidence exists regarding cancer-specific mortality (CSM) differences between trimodal therapy and other non-extirpative multimodal treatment options such as radiotherapy alone after transurethral resection (TURBT + RT) or chemotherapy alone after transurethral resection (TURBT + CT). METHODS: Within the Surveillance, Epidemiology, and End Results database (2004-2020), we identified T2N0M0 patients treated with either trimodal therapy, TURBT + CT, or TURBT + RT. Temporal trends described trimodal therapy vs. TUBRT + CT vs. TURBT + RT use over time. Survival analyses consisting of Kaplan-Meier plots and multivariable Cox regression (MCR) models addressed CSM according to each treatment modality. RESULTS: 3729 (40%) patients underwent TMT vs. 4030 (43%) TURBT + CT vs. 1599 (17%) TURBT + RT. Over time, trimodal therapy use (Estimating annual percent change, EAPC: +1.2%, p = 0.01) and TURBT + CT use increased (EAPC: +1.5%, p = 0.01). In MCR models, relative to trimodal therapy, TURBT + CT exhibited 1-14-fold higher CSM and TURBT + RT 1.68-fold higher CSM. In a subgroup analysis, TURBT + RT was associated with 1.42-fold higher CSM than TURBT + CT (p < 0.001). CONCLUSIONS: Strict trimodal therapy that includes both CT and RT after TURBT offers the best cancer control. When strict trimodal therapy cannot be delivered, cancer-specific survival outcomes appear to be superior with TURBT + chemotherapy compared to TURBT + RT.

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.

Use of inpatient palliative care in metastatic urethral cancer.

BACKGROUND: In metastatic urethral cancer, temporal trends, and patterns of inpatient palliative care (IPC) use are unknown. METHODS: Relying on the National Inpatient Sample (2006-2019), metastatic urethral cancer patients were stratified according to IPC use. Estimated annual percentage changes (EAPC) analyses and multivariable logistic regression models (LRM) for the prediction of IPC use were fitted. RESULTS: Of 1,106 metastatic urethral cancer patients, 199 (18%) received IPC. IPC use increased from 5.8 to 28.0% over time in the overall cohort (EAPC +9.8%; P < 0.001), from <12.5 to 35.1% (EAPC +11.2%; P < 0.001), and from <12.5 to 24.7% (EAPC +9.4%; P = 0.01) in respectively females and males. Lowest IPC rates were recorded in the Midwest (13.5%) vs. highest in the South (22.5%). IPC patients were more frequently female (44 vs. 37%), and more frequently exhibited bone metastases (45 vs. 34%). In multivariable LRM, female sex (multivariable odds ratio [OR] 1.46, 95% confidence interval [CI] 1.05-2.02; P = 0.02), and bone metastases (OR 1.46, 95%CI 1.02-2.10; P = 0.04) independently predicted higher IPC rates. Conversely, hospitalization in the Midwest (OR 0.53, 95%CI 0.31-0.91; P = 0.02), and in the Northeast (OR 0.48, 95%CI 0.28-0.82; P = 0.01) were both associated with lower IPC use than hospitalization in the West. CONCLUSION: IPC use in metastatic urethral cancer increased from a marginal rate of 5.8% to as high as 28%. Ideally, differences according to sex, metastatic site, and region should be addressed to improve IPC use rates.

The effect of race/ethnicity on cancer-specific mortality after trimodal therapy.

INTRODUCTION: Trimodal therapy (TMT) is the most validated bladder-sparing treatment for organ-confined urothelial carcinoma of the urinary bladder (OC UCUB, namely cT2N0M0). However, it is unknown if barriers to the use of TMT or cancer-specific mortality (CSM) differences exist according to race/ethnicity. We addressed this knowledge gap. MATERIAL AND METHODS: Within the Surveillance, Epidemiology, and End Results database (2004-2020), we identified OC UCUB patients aged from 18 to 85 treated with radical cystectomy (RC) or TMT. Temporal trends described TMT versus RC use over time. Subsequently, in the subgroup of TMT-treated patients, survival analyses consisting of Kaplan-Meier plots and multivariable Cox regression (MCR) models addressed CSM according to race/ethnicity. RESULTS: Among 19,501 assessable patients, 15,336 (79%) underwent RC versus 4165 TMT (21%). Overall, of all races/ethnicities, 16,245 (83.3%) were White Americans, 1215 (6.3%) Hispanics, 1160 (5.9%) African Americans, and 881 (4.5%) Asian/Pacific Islanders. Among TMT-treated patients, 3460 (83.1%) were White Americans, 298 (7.1%) African Americans, 218 (5.3%) Hispanics, and 189 (4.5%) Asian/Pacific Islanders. The lowest rate of TMT use relative to RC and TMT patients was recorded in Hispanics (17.9%). Over time, TMT use increased in White Americans (EAPC: + 4.5%, p = 0.001) and Asians/Pacific Islanders (EAPC: + 5.2%, p = 0.003), but not in others. Kaplan-Meier analyses showed median CSM of 49 months, 41 months, and 34 months and not reached in White Americans, Hispanics, African Americans, and Asian/Pacific Islanders, respectively (p = 0.02). In MCR models, two race/ethnicity subgroups independently predicted either worse (African Americans, HR: 1.20, p = 0.02) or better CSM (Asian/Pacific Islanders, HR: 0.75, p = 0.02). CONCLUSION: Race/ethnicity affects both access to TMT (lower access in Hispanics) as well as survival after TMT (better in Asians/Pacific Islanders and worse in African Americans).

Trimodal therapy effect on survival in urothelial vs non-urothelial bladder cancer.

OBJECTIVE: To address cancer-specific mortality free-survival (CSM-FS) differences in patients with urothelial carcinoma of the urinary bladder (UCUB) vs non-UCUB who underwent trimodal therapy (TMT), according to organ confined (OC: T2N0M0) vs non-organ confined (NOC: T3-4NanyM0 or TanyN1-3M0) clinical stages. PATIENTS AND METHODS: Within the Surveillance, Epidemiology, and End Results database (2004-2020), we identified patients with cT2-T4N0-N3M0 bladder cancer treated with TMT, defined as the combination of transurethral resection of bladder tumour, chemotherapy, and radiotherapy. Temporal trends described TMT use over time. Kaplan-Meier plots and multivariable Cox regression (MCR) models addressed CSM in UCUB vs non-UCUB according to OC vs NOC stages. RESULTS: Of 5130 assessable TMT-treated patients, 425 (8%) harboured non-UCUB vs 4705 (92%) who had UCUB. The TMT rates increased for patients with OC UCUB from 92.4% to 96.8% (estimated annual percentage change of 0.4%, P < 0.001), but not in the NOC stages (P = 0.3). In the OC stage, the median CSM-FS was 36 months in patients with non-UCUB vs 60 months in those with UCUB, respectively (P = 0.01). Conversely, in the NOC stage, the median CSM-FS was 23 months both in UCUB and non-UCUB (P = 0.9). In the MCR models addressing OC stage, non-UCUB histology independently predicted higher CSM (hazard ratio 1.45, P = 0.004), but not in the NOC stage (P = 0.9). CONCLUSION: In OC UCUB, TMT rates have increased over time in a guideline-consistent fashion. Patients with OC non-UCUB treated with TMT showed a CSM disadvantage relative to OC UCUB. In the NOC stage, use of TMT resulted in dismal CSM, regardless of UCUB vs non-UCUB histology.

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%).

Perioperative Complications and In-Hospital Mortality in Partial and Radical Nephrectomy Patients with Heart-Valve Replacement.

BACKGROUND: In-hospital mortality and complication rates after partial and radical nephrectomy in patients with history of heart-valve replacement are unknown. PATIENTS AND METHODS: Relying on the National Inpatient Sample (2000-2019), kidney cancer patients undergoing partial or radical nephrectomy were stratified according to presence or absence of heart-valve replacement. Multivariable logistic and Poisson regression models addressed adverse hospital outcomes. RESULTS: Overall, 39,673 patients underwent partial nephrectomy versus 94,890 radical nephrectomy. Of those, 248 (0.6%) and 676 (0.7%) had a history of heart-valve replacement. Heart-valve replacement patients were older (median partial nephrectomy 69 versus 60 years; radical nephrectomy 71 versus 63 years), and more frequently exhibited Charlson comorbidity index ≥ 3 (partial nephrectomy 22 versus 12%; radical nephrectomy 32 versus 23%). In partial nephrectomy patients, history of heart-valve replacement increased the risk of cardiac complications [odds ratio (OR) 4.33; p < 0.001), blood transfusions (OR 2.00; p < 0.001), intraoperative complications (OR 1.53; p = 0.03), and longer hospital stay [rate ratio (RR) 1.25; p < 0.001], but not in-hospital mortality (p = 0.5). In radical nephrectomy patients, history of heart-valve replacement increased risk of postoperative bleeding (OR 4.13; p < 0.001), cardiac complications (OR 2.72; p < 0.001), intraoperative complications (OR 1.53; p < 0.001), blood transfusions (OR 1.27; p = 0.02), and longer hospital stay (RR 1.12; p < 0.001), but not in-hospital mortality (p = 0.5). CONCLUSIONS: History of heart-valve replacement independently predicted four of twelve adverse outcomes in partial nephrectomy and five of twelve adverse outcomes in radical nephrectomy patients including intraoperative and cardiac complications, blood transfusions, and longer hospital stay. Conversely, no statistically significant differences were observed in in-hospital mortality.

Iron homeostasis alterations and erectile dysfunction: A new issue in erectile disfunction treatment?

To the Editor, Erectile dysfunction (ED) is one of the most prevalent conditions affecting men globally, with significant psychological and social consequences. The prevalence varies across different populations, and it is estimated around 50% in men aged between 40 to 70. The etiology of ED is multifactorial, involving a complex crosstalk between psychological, hormonal, neurogenic, vascular, and structural factors [...].

Forest disturbance increases functional diversity but decreases phylogenetic diversity of an arboreal tropical ant community.

Tropical rainforest trees host a diverse arthropod fauna that can be characterised by their functional diversity (FD) and phylogenetic diversity (PD). Human disturbance degrades tropical forests, often coinciding with species invasion and altered assembly that leads to a decrease in FD and PD. Tree canopies are thought to be particularly vulnerable, but rarely investigated. Here, we studied the effects of forest disturbance on an ecologically important invertebrate group, the ants, in a lowland rainforest in New Guinea. We compared an early successional disturbed plot (secondary forest) to an old-growth plot (primary forest) by exhaustively sampling their ant communities in a total of 852 trees. We expected that for each tree community (1) disturbance would decrease FD and PD in tree-dwelling ants, mediated through species invasion. (2) Disturbance would decrease ant trait variation due to a more homogeneous environment. (3) The main drivers behind these changes would be different contributions of true tree-nesting species and visiting species. We calculated FD and PD based on a species-level phylogeny and 10 ecomorphological traits. Furthermore, we assessed by data exclusion the influence of species, which were not nesting in individual trees (visitors) or only nesting species (nesters), and of non-native species on FD and PD. Primary forests had higher ant species richness and PD than secondary forest. However, we consistently found increased FD in secondary forest. This pattern was robust even if we decoupled functional and phylogenetic signals, or if non-native ant species were excluded from the data. Visitors did not contribute strongly to FD, but they increased PD and their community weighted trait means often varied from nesters. Moreover, all community-weighted trait means changed after forest disturbance. Our finding of contradictory FD and PD patterns highlights the importance of integrative measures of diversity. Our results indicate that the tree community trait diversity is not negatively affected, but possibly even enhanced by disturbance. Therefore, the functional diversity of arboreal ants is relatively robust when compared between old-growth and young trees. However, further study with higher plot-replication is necessary to solidify and generalise our findings.

Intra-scrotal epidermoid cyst rupture misdiagnosed as a testicular prosthesis rupture: A case report.

Testicular cancers represent about 5 % of all urological tumors. Most patients who undergo radical orchiectomy (RO) decide to place a testicular prosthesis, for a cosmetic result and to accept the testicular loss. Among all late complications, a spontaneous prosthesis rupture is a rare event contrary to penile prosthesis. The present study reported the case of a 53-year-old Italian man has presented to our department principally for a suspicious rupture of testicular implant, placed twenty years before after a RO. Despite the findings at scrotal ultrasonography, at final histology, the mass was identified as spontaneously broken intra-scrotal epidermoid cyst.

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.

Lower urinary tract symptoms in young-middle aged males with a diagnosis of obstructive sleep apnea syndrome.

BACKGROUND: The aim of the current study is to measure the prevalence and the potential role of International Prostate Symptom Score (IPSS) score as a predictor of obstructive sleep apnea syndrome (OSAS) in male experienced lower urinary tract symptoms (LUTS). METHODS: A cross-sectional web-based Italian survey was administered via Google Forms between July 17 and October 31, 2022. The urinary functioning was measured through the IPSS questionnaire. Specifically, we considered symptoms occurring more than "about half the time" (score ≥ 3) as bothering symptoms. Multivariable logistic regression models (LRMs) adjusting for age, body mass index (BMI), International Index of Erectile Function-5, IPSS, and hypertension were fitted to predict OSAS in the cohort of men responding to the survey and experiencing LUTS. RESULTS: Overall, 58 (24.4%) patients had a confirmed diagnosis of OSAS. The overall median IPSS was 5 (inter quartile range [IQR]: 3-8), respectively. According to IPSS items, 24 (10%), 44 (18.4%), 12 (5%), 12 (5%), 12 (5%), 11 (4.6%), 63 (26.4%) patients exhibit incomplete bladder emptying, urinary frequency, intermittency, urgency, weak stream, straining, nocturia with a score ≥ 3, respectively. After multivariable LRMs predicting the developing OSAS, age (odds ratio [OR]: 1.09, p < 0.001), BMI (OR:1.12, p < 0.001) and IPSS total score (OR:1.08, p = 0.02) were independent predicting factors. CONCLUSION: This analysis revealed that the IPSS total score, age, and BMI are independent predictors of OSAS in males. In this context, the use of IPSS in daily practice could be helpful in assessing the LUTS presence and in supporting physicians to identify a hidden sleep apnea condition.

Are Excessive Daytime Sleepiness and Lower Urinary Tract Symptoms the Triggering Link for Mental Imbalance? An Exploratory Post Hoc Analysis.

BACKGROUND: Both lower urinary tract symptoms (LUTS) and excessive daytime sleepiness (EDS) could negatively impair the patients' quality of life, increasing the sensitivity to psychological distress that results in mental health disorders. The relationships of both urinary and respiratory domains with psychological distress in obstructive sleep apnea patients is still underestimated. METHODS: This study was a post hoc analysis of a web-based Italian survey, which included 1998 participants. Three hierarchical multiple linear regression analyses with psychological distress as dependent variable were performed on the study of 1988 participants enrolled in the final analysis. Cohen's f2 was used for the assessment of the effect size. RESULTS: From the hierarchical multiple linear regression analyses, it emerged that the final statistical model (including sociodemographic characteristics, comorbidities, perceived urinary function, and excessive daytime sleepiness) for all dimensions accounted for 16.7% of the variance in psychological distress, with a medium effect size (f2 = 0.15). CONCLUSIONS: People reported psychological distress was impaired by the presence of LUTS and EDS. Specifically, our study showed that higher levels of distress were scored especially in young women exhibiting urinary symptoms and with high values of daytime sleepiness.
