Is multiparametric MRI always needed in biopsy-naïve patients with abnormal digital rectal examination? A single-institutional experience combining clinical and micro-ultrasonography-based factors to optimize prostate cancer detection.

PURPOSE: To assess the diagnostic performance of microultrasound-targeted biopsy (microUSTBx) and systematic biopsy (SBx) in detecting clinically significant prostate cancer (csPCa) among men with abnormal digital rectal examination (DRE) and suspicious lesions at multiparametric magnetic resonance imaging (mpMRI), and to compare the diagnostic performance of this approach with a mpMRI-guided targeted biopsy (MTBx) plus SBx-based strategy. METHODS: Biopsy-naïve men with suspicious lesions at mpMRI and abnormal DRE were prospectively evaluated between October 2017 and January 2023. csPCa detection rate by microUSTBx plus SBx and MTBx plus SBx was assessed and then compared by McNemar's test. The added value of prostate-specific antigen density (PSAd) was also evaluated. RESULTS: Overall, 182 biopsy naïve men were included. MicroUSTBx plus SBx achieved comparable detection rate to MTBx plus SBx in diagnosis of ciPCa and csPCa (ciPCa: 9.3% [17/182] vs 10% [19/182]; csPCa: 63% [114/182] vs 62% [113/182]). MicroUSTBx outperformed MTBx (ciPCa: 5.5% [10/182] vs 6.0% [11/182]; csPCa: 57% [103/182] vs 54% [99/182]). Using microUSTBx plus SBx would have avoided 68/182 (37%) unnecessary mpMRI, while missing only 2/116 (1.7%) csPCa. The decision curve analysis of suspicious microUS plus PSAd ≥ 0.15 ng/ml showed higher net benefit in the ability to identify true positives and reduce the number of unnecessary prostate biopsy in this subcategory of patients. CONCLUSIONS: The combination of microUSTBx and SBx showed equal diagnostic performance to an mpMRI-based approach in biopsy-naïve patients with an abnormal DRE. The combination of this approach with PSAd maximize the diagnostic accuracy while lowering the need for unnecessary biopsies.

The effect of limited english proficiency on prostate-specific antigen screening in American men.

PURPOSE: To evaluate how limited English proficiency (LEP) impacts the prevalence of prostate-specific antigen (PSA) screening in a contemporary, nationally representative cohort of men in the USA. METHODS: The Medical Expenditure Panel Survey was utilized to identify the prevalence of PSA screening between 2013 and 2016 among men ≥ 55. Men who speak a language other than English at home were stratified by self-reported levels of English proficiency (men who speak English very well, well, not well, or not at all). Survey weights were applied, and groups were compared using the adjusted Wald test. A multivariable logistic regression model was used to identify predictors of PSA screening adjusting for patient-level covariates. RESULTS: The cohort included 2,889 men, corresponding to a weighted estimate of 4,765,682 men. 79.6% of men who speak English very well reported receiving at least one lifetime PSA test versus 58.4% of men who do not speak English at all (p < 0.001). Men who reported not speaking English at all had significantly lower prevalence of PSA screening (aOR 0.56; 95% CI 0.35-0.91; p = 0.019). Other significant predictors of PSA screening included older age, income > 400% of the federal poverty level, insurance coverage, and healthcare utilization. CONCLUSIONS: Limited English proficiency is associated with significantly lower prevalence of PSA screening among men in the USA. Interventions to mitigate disparities in prostate cancer outcomes should account for limited English proficiency among the barriers to guideline-concordant care.

Racial differences in knowledge, attitudes, and sources of information about germline cancer genetic testing in the U.S.A.: An analysis of the health information National Trends Survey System.

PURPOSE: To understand racial disparities in germline cancer genetic testing and the role of prior knowledge, attitudes, and sources of information. METHODS: A cross-sectional analysis of the Health Information National Trends Survey 5 (HINTS 5) was conducted between February 24th and June 15th, 2020. The study aimed to investigate knowledge and receipt of genetic testing, attitudes toward the importance of genetic testing in preventing, detecting, and treating cancer, and information sources of genetic testing in the United States of America. RESULTS: Non-Hispanic Black (NHB) and Hispanic race/ethnicity were associated with lower odds of being informed about genetic testing, whereas those of NHB race were more likely to endorse the importance of genetic testing in cancer prevention and treatment. Regarding sources of information about genetic testing: Non-Hispanic Asians were less likely to be informed about genetic testing from television (Mean Predicted Probability (MPP) 0.38 95%CI; 0.21-0.55, (Adjusted Risk Difference) ARD vs. Non-Hispanic White (NHW); -0.228, p = 0.01), NHB were less likely to report being informed about genetic testing from social media (MPP 0.27 95%CI; 0.20-0.34, ARD vs. NHW; -0.139, p < 0.01). CONCLUSIONS: NHB and Hispanic groups face unequal access to information about genetic testing. There are significant race-based differences in information sources. These differences could be used to promote equitable access to cancer genetic testing.

Effect of type of definitive treatment on race-based differences in prostate cancer-specific survival.

BACKGROUND: Racial and ethnic disparities in prostate cancer (PCa) mortality are partially mediated by inequities in quality of care. Intermediate- and high-risk PCa can be treated with either surgery or radiation, therefore we designed a study to assess the magnitude of race-based differences in cancer-specific survival between these two treatment modalities. METHODS: Non-Hispanic Black (NHB) and non-Hispanic White (NHW) men with localized intermediate- and high-risk PCa, treated with surgery or radiation between 2004 and 2015 in the Surveillance, Epidemiology and End Results database were included in the study and followed until December 2018. Unadjusted and adjusted survival analyses were employed to compare cancer-specific survival by race and treatment modality. A model with an interaction term between race and treatment was used to assess whether the type of treatment amplified or attenuated the effect of race/ethnicity on prostate cancer-specific mortality (PCSM). RESULTS: 15,178 (20.1%) NHB and 60,225 (79.9%) NHW men were included in the study. NHB men had a higher cumulative incidence of PCSM (p = 0.005) and were significantly more likely to be treated with radiation than NHW men (aOR: 1.89, 95% CI: 1.81-1.97, p < 0.001). In the adjusted models, NHB men were significantly more likely to die from PCa compared with NHW men (aHR: 1.18, 95% CI: 1.03-1.35, p = 0.014), and radiation was associated with a significantly higher odds of PCSM (aHR: 2.10, 95% CI: 1.85-2.38, p < 0.001) compared with surgery. Finally, the interaction between race and treatment on PCSM was not significant, meaning that no race-based differences in PCSM were found within each treatment modality. CONCLUSIONS: NHB men with intermediate- and high-risk PCa had a higher rate of PCSM than NWH men in a large national cancer registry, though NHB and NHW men managed with the same treatment achieved similar PCa survival outcomes. The higher tendency for NHB men to receive radiation was similar in magnitude to the difference in cancer survival between racial and ethnic groups.

Diagnostic accuracy of multiparametric MRI- and microultrasound-targeted biopsy in biopsy-naïve patients with a PI-RADS 5 lesion: a single-institutional study.

PURPOSE: To evaluate the diagnostic accuracy of multiparametric magnetic resonance imaging (MRI)- and microultrasound (microUS)-guided targeted biopsy (TBx) in detecting prostate cancer (PCa) and clinically significant (cs) PCa among men with Prostate Imaging Reporting and Data System (PI-RADS 5) lesions and to compare this combined TBx (CTBx) strategy with CTBx plus systemic biopsy (SBx). METHODS: One hundred and thirty-six biopsy-naïve patients with PI-RADS 5 lesion at multiparametric MRI undergoing CTBx plus SBx were retrospectively evaluated. Analysis of diagnostic performance of microUS-TBx, MRI-TBx, CTBx, SBx and combined CTBx plus SBx was performed. Cost (downgrade, upgrade and biopsy core) to effectiveness (detection rate) was compared. RESULTS: CTBx achieved a comparable detection rate to CTBx plus SBx in diagnosis of PCa and csPCa (PCa: 78.7% [107/136] vs 79.4% [108/136]; csPCa: 67.6% [92/136] vs 67.6% [92/136]; p > 0.05) and outperformed SBx (PCa: 58.8% [80/136]; csPCa: 47.8% [65/136]; p < 0.001). Using CTB would have avoided 41.1% (56/136) unnecessary SBx, without missing any csPCa. The rate of any upgrading or csPCa upgrading was significantly higher by SBx than by CTBx [33/65 (50.8%) vs 17/65 (26.1%) and 20/65 (30.8%) vs 4/65 (6.15%), respectively, p < 0.05]. Considering csPCa detection rate, microUS showed high sensitivity and positive predictive value (94.6%, 87.9%, respectively), with lower specificity and negative predictive value (25.0% and 44.4%, respectively). At multivariable logistic regression models, positive microUS was identified as an independent predictor of csPCa (p = 0.024). CONCLUSIONS: A combined microUS/MRI-TBx approach could be the ideal imaging tool for characterizing primary disease in PI-RADS five patients, allowing SBx to be avoided.

Contemporary patterns of local ablative therapies for prostate cancer at United States cancer centers: results from a national registry.

PURPOSE: To describe the national-level patterns of care for local ablative therapy among men with PCa and identify patient- and hospital-level factors associated with the receipt of these techniques. METHODS: We retrospectively interrogated the National Cancer Database (NCDB) for men with clinically localized PCa between 2010 and 2017. The main outcome was receipt of local tumor ablation with either cryo- or laser-ablation, and "other method of local tumor destruction including high-intensity focused ultrasound (HIFU)". Patient level, hospital level, and demographic variables were collected. Mixed effect logistic regression models were fitted to identify separately patient- and hospital-level predictors of receipt of local ablative therapy. RESULTS: Overall, 11,278 patients received ablative therapy, of whom 78.8% had cryotherapy, 15.6% had laser, and 5.7% had another method including HIFU. At the patient level, men with intermediate-risk PCa were more likely to be treated with local ablative therapy (OR 1.05; 95% CI 1.00-1.11; p = 0.05), as were men with Charlson Comorbidity Index > 1 (OR 1.36; 95% CI 1.29-1.43; p < 0.01), men between 71 and 80 years (OR 3.70; 95% CI 3.43-3.99; p < 0.01), men with Medicare insurance (OR 1.38; 95% 1.31-1.46; p < 0.01), and an income < $47,999 (OR 1.16; 95% CI 1.06-1.21; p < 0.01). At the hospital-level, local ablative therapy was less likely to be performed in academic/research facilities (OR 0.45; 95% CI 0.32-0.64; p < 0.01). CONCLUSIONS: Local ablative therapy for PCa treatment is more commonly offered among older and comorbid patients. Future studies should investigate the uptake of these technologies in non-hospital-based settings and in light of recent changes in insurance coverage.

Promoting the use of the PI-QUAL score for prostate MRI quality: results from the ESOR Nicholas Gourtsoyiannis teaching fellowship.

OBJECTIVES: The Prostate Imaging Quality (PI-QUAL) score is a new metric to evaluate the diagnostic quality of multiparametric magnetic resonance imaging (MRI) of the prostate. This study assesses the impact of an intervention, namely a prostate MRI quality training lecture, on the participant's ability to apply PI-QUAL. METHODS: Sixteen participants (radiologists, urologists, physicists, and computer scientists) of varying experience in reviewing diagnostic prostate MRI all assessed the image quality of ten examinations from different vendors and machines. Then, they attended a dedicated lecture followed by a hands-on workshop on MRI quality assessment using the PI-QUAL score. Five scans assessed by the participants were evaluated in the workshop using the PI-QUAL score for teaching purposes. After the course, the same participants evaluated the image quality of a new set of ten scans applying the PI-QUAL score. Results were assessed using receiver operating characteristic analysis. The reference standard was the PI-QUAL score assessed by one of the developers of PI-QUAL. RESULTS: There was a significant improvement in average area under the curve for the evaluation of image quality from baseline (0.59 [95 % confidence intervals: 0.50-0.66]) to post-teaching (0.96 [0.92-0.98]), an improvement of 0.37 [0.21-0.41] (p < 0.001). CONCLUSIONS: A teaching course (dedicated lecture + hands-on workshop) on PI-QUAL significantly improved the application of this scoring system to assess the quality of prostate MRI examinations. KEY POINTS: • A significant improvement in the application of PI-QUAL for the assessment of prostate MR image quality was observed after an educational intervention. • Appropriate training on image quality can be delivered to those involved in the acquisition and interpretation of prostate MRI. • Further investigation will be needed to understand the impact on improving the acquisition of high-quality diagnostic prostate MR examinations.

Does the 5-item Frailty Index predict surgical complications of endoscopic surgical management for benign prostatic obstruction? An analysis of the ACS-NSQIP.

PURPOSE: To assess whether the 5-item Frailty Index (5i-FI) predicts surgical complications of endoscopic surgery for benign prostatic obstruction (BPO) and examine the rates of these complications across BPO surgical modalities adjusting for patient frailty. METHODS: The ACS-NSQIP registry was queried for patients who underwent transurethral resection of the prostate (TURP), photoselective vaporization of the prostate (PVP), and laser enucleation of the prostate (LEP) between 2009 and 2019. Patients' frailties were estimated using the 5i-FI. We assessed the association between 5i-FI and the following endpoints: all complications, major complications (Clavien-Dindo ≥ 3), length of stay (LOS) ≥ 2 days, and 30-day postoperative readmission. Inverse probability of treatment weighting (IPTW) was used to account for selection bias in treatment allocation. IPTW-adjusted rates for 30-day complications were compared between surgical modalities. RESULTS: The cohort included 38,399 (62.6%) TURP, 19,121 (31.2%) PVP, and 3797 (6.2%) LEP. Men with 5i-FI score ≥ 2 were more likely to receive TURP (22.7%) and PVP (22.5%) than LEP (18.8%). 5i-FI ≥ 2 was associated with higher odds of all complications (OR 1.50), major complications (OR 1.63), LOS ≥ 2 (OR 1.31), and readmission (OR 1.65). After IPTW, LEP had the lowest rates for all complications (6.29%; 95%CI 5.48-7.20), major complications (2.30%; 95%CI 1.83-2.89), and readmission (3.80%; 95%CI 3.18-4.53). CONCLUSION: The 5i-FI score is an independent predictor of 30-day postoperative surgical complications after endoscopic BPO surgery. After IPTW, LEP and PVP were associated with lower rates of complications than TURP. However, frail patients were less likely to undergo PVP and LEP. Preoperative frailty assessment could improve risk stratification before BPO surgery.

The Microbiome of Catheter Collected Urine in Males with Bladder Cancer According to Disease Stage.

PURPOSE: The dogma that urine is sterile has been overturned and dysbiosis of the urinary microbiome has been linked to many urological disorders. We tested the hypothesis that the urinary microbial composition may be different between men with or without bladder cancer in catheter collected urines, bladder washouts and midstream voided urines, and may be dependent on tumor staging. MATERIALS AND METHODS: Liquid samples were collected from male patients with bladder cancer, and sex and age matched nonneoplastic controls. Total DNA was extracted and processed for 16S rRNA gene sequencing. Bioinformatic analysis for microbial classification was performed to assess diversity and variations. RESULTS: The urinary microbiome associated with catheter collected urine samples of patients with bladder cancer was characterized by a significantly increased abundance of Veillonella (p=0.04) and Corynebacterium (p=0.03), and decreased Ruminococcus (p=0.03) compared to controls, with differences exacerbating with disease progression. Compared to catheterized urines, bladder cancer washouts showed the specific increase of some taxa, like Burkholderiaceae (p=0.014), whereas midstream urines were enriched in Streptococcus (p <0.0001), Enterococcus (p <0.0001), Corynebacterium (p=0.038) and Fusobacterium (p <0.0001). CONCLUSIONS: The bladder is colonized by endogenous bacteria and microbial modifications characterize the microbiome of patients with bladder cancer. Different microbial compositions can be characterized by changing sampling strategy. These results pave the way for exploring new diagnostic and therapeutic options based on the manipulation of the bacterial community.

Feasibility, safety, and efficacy of ultrasound-guided transperineal laser ablation for the treatment of benign prostatic hyperplasia: a single institutional experience.

PURPOSE: To evaluate the feasibility, safety, and efficacy of ultrasound-guided transperineal laser ablation (TPLA) as a new minimally invasive surgical therapy (MIST) for the treatment of lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: Under local anesthesia and conscious sedation up to two laser fibers for each prostatic lobe were inserted under US-guidance by a percutaneous approach. TPLA was performed using a continuous wave diode laser (SoracteLite-EchoLaserX4) able to generate a light-induced thermal heating and subsequent coagulative necrosis of the prostatic tissue. Patients were evaluated at 3, 6, and 12 months after TPLA. RESULTS: Twenty-two consecutive patients were prospectively enrolled (median age 61.9 years). All procedures were well tolerated and no procedural complications were recorded. Median catheterization time was 7 days, while the median hospitalization time was 1 day. Three out of twenty-two patients (13.6%) experienced acute urinary retention and two (9.1%) of them urinary tract infection requiring major antibiotic treatment. At 3, 6, and 12 months, median prostate volume significantly decreased by a - 21.3%, - 29%, and - 41%, respectively. At the same time point, median IPSS was 8 (- 63.6%), 5 (- 74%), and 6 (- 75%), while median QoL score was 1 in all the scheduled timepoints of follow-up. The median postoperative Qmax at 3, 6, and 12 months improved by + 57.8%, + 98%, and + 115.8%, respectively. Ejaculatory function was preserved in 21 out of 22 patients (95.5%). CONCLUSIONS: TPLA of the prostate appears to be a promising MIST for BPH. Long-term results and comparative studies against standard treatments are warranted before implementations of this technique in the urologist's armamentarium.

Retrotrigonal muscular layer sling associated with total anatomical reconstruction in robot-assisted radical prostatectomy and early continence.

BACKGROUND AND PURPOSE: Urinary continence (UC) represents the main non-oncological goal in patients undergoing robotic-assisted radical prostatectomy (RARP). To evaluate the efficacy in early UC achievement, we described a new sling technique using the retrotrigonal muscular layer (TZ sling) combined with total anatomical reconstruction (TAR). PATIENTS AND METHODS: We prospectively enrolled 407 consecutive prostate cancer (PC) patients undergoing RARP between May 2017 and January 2020. The first 250 patients underwent only TAR, while the following 157 patients TAR + TZ sling, by isolating and anchoring the retrotrigonal muscular layer to the pubic bone with 2 bilateral sutures. We defined UC as ≤ 1 pad/die, which was assessed after catheter removal at 1, 4 and 12wk using the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) score. Sling-related operative time and post-operative complications were analyzed. RESULTS: In the TAR group, the UC rates at the 1, 4 and 12wk were 58%, 66% and 86%; in the TAR + TZ sling group 72%, 76% and 88%, respectively. A statistically significant difference was observed in the two groups at 1wk (p = 0.0049) and 4wk (p = 0.035) favoring the TZ sling surgical strategy. This difference in UC rates was lost at 12wk (p ≥ 0.05). No statistically significant differences in operative time, acute urinary retentions and other complication rates were observed between the two groups (p = NS). CONCLUSIONS: We have described a new, safe, feasible modification of RARP using a sling with the retrotrigonal muscular layer associated with TAR. We have demonstrated a statistically significant improvement in early UC rate in patients who are undergoing TAR and TZ sling compared to undergoing only TAR.

Clinical performance of Xpert Bladder Cancer (BC) Monitor, a mRNA-based urine test, in active surveillance (AS) patients with recurrent non-muscle-invasive bladder cancer (NMIBC): results from the Bladder Cancer Italian Active Surveillance (BIAS) project.

PURPOSE: To investigate the clinical performance of a new mRNA-based urine test, aiming to avoid unnecessary follow-up cystoscopy in patients under active surveillance (AS) for recurrent NMIBC. METHODS: This is a prospective cohort study enrolling patients with history of low-grade (LG) NMIBC, who developed a recurrence during the follow-up and underwent AS. Their urinary samples were analyzed by Xpert BC Monitor (Cepheid, Sunnyvale, CA, USA). The primary endpoint was to investigate if Xpert BC Monitor could avoid unnecessary cystoscopy during the follow-up period. Its sensitivity, specificity, PPVs and NPVs were calculated. A cutoff of 0.4 "linear discriminant analysis" (LDA) was optimized for the AS setting. RESULTS: The cohort consisted of 106 patients with a mean age of 72 ± 9.52 and a median follow-up from AS start of 8.8 (range 0-56.5) months. No statistically significant difference was found for the mean age, smoker status, lesion size, and number of lesions with a cutoff of 0.4. Of 106 patients, 22 (20.8%) were deemed to require treatment because of cystoscopic changes in size and/or number of lesions during the follow-up period. Using a cutoff value of < 0.4, 34 (33.7%) cystoscopies could be avoided due to low LDA value, missing 2/22 (9%) failures, none with high-grade (HG) NMIBC. Further research on larger population remains mandatory before its clinical use. CONCLUSION: Xpert BC Monitor seems to be a reliable assay, which might avoid unnecessary cystoscopies without missing HG NMIBC when its cutoff is optimized for the AS setting.

Undiagnosed prediabetes is highly prevalent in primary infertile men - results from a cross-sectional study.

OBJECTIVE: To study the prevalence and the risk associated with prediabetes (PreDM) in primary infertile men. PATIENTS AND METHODS: Data from 744 infertile men were analysed. Health-significant comorbidities were scored with the Charlson Comorbidity Index (CCI). Serum hormones were measured in every man. Semen analysis was based on 2010 World Health Organization (WHO) reference criteria. PreDM was defined according to the clinical criteria detailed by the American Diabetes Association (Diabetes Care 2014; 37 (Suppl. 1): S81). Descriptive statistics and logistic regression analyses tested the association between PreDM status, hormonal milieu and seminal parameters. The predictive accuracy of all variables was evaluated using the area under the curve, and the clinical net benefit estimated by decision curve analysis (DCA). RESULTS: Of the 744 men, PreDM was found in 114 (15.4%). Men with PreDM (+PreDM) were older, had higher CCI scores, lower total testosterone and sex hormone-binding globulin but higher follicle-stimulating hormone (FSH) and 17ß-oestradiol values compared to those without PreDM (-PreDM) (all P ≤ 0.04). Higher sperm DNA fragmentation index (DFI; P = 0.014) and idiopathic non-obstructive azoospermia (iNOA; P < 0.001) were found more frequently in +PreDM men. At multivariable logistic regression analysis, older age, FSH and iNOA (all P ≤ 0.04) were significantly associated with +PreDM status. DCA demonstrated a clinical net benefit in discriminating men at higher risk of a +PreDM status. CONCLUSIONS: About 15% of primary infertile men had criteria suggestive of undiagnosed PreDM. A PreDM status was associated with a greater risk of hypogonadism, higher DFI values and iNOA status. Age, FSH values and iNOA status could be considered as useful parameters to recognise men with PreDM and implement early preventive interventions in those men at risk of the consequences from poor glycaemic control.

Unrecognized Prediabetes Is Highly Prevalent in Men With Erectile Dysfunction-Results From a Cross-Sectional Study.

INTRODUCTION: The association between prediabetes (PreDM) and erectile dysfunction (ED) has been analyzed scantly. AIM: To assess the association between PreDM and erectile function (EF) in a cohort of white European men with ED. METHODS: Demographic, clinical, and laboratory data from 372 consecutive men were analyzed. Health-significant comorbidities were scored with the Charlson Comorbidity Index (CCI). Patients were invited to complete the International Index of Erectile Function (IIEF)-EF domain questionnaire. The EF domain was categorized according to Cappelleri's criteria. Men were defined as having PreDM according to the criteria defined by the American Diabetes Association (2015). Descriptive statistics and logistic regression models tested the association between clinical variables and PreDM status and severe ED. MAIN OUTCOME MEASURES: We assessed the prevalence of PreDM in our cohort of men with ED and the potential association of PreDM and sexual health within the same cohort. RESULTS: Of 372 men, +PreDM was found in 86 (23.1%) patients. Men with +PreDM had lower total testosterone (tT), higher triglycerides, and higher total cholesterol values (all P < .03) than those without PreDM. Likewise, +PreDM patients had a higher rate of CCI ≥1 (P = .03) and more frequently had severe ED (P = .013) compared with -PreDM. Age (OR 1.03; P = .01); lower tT (OR 0.81; P = .02); and severe ED (OR 3.37; P = .004) were associated with +PreDM status, after accounting for BMI, CCI, alcohol consumption, and cigarette smoking. Similarly, age (OR 1.02; P = .02) and +PreDM (OR 2.02; P = .02) were associated with severe ED, after accounting for other clinical variables. CLINICAL IMPLICATIONS: Identifying +PreDM status in ED men is clinically relevant in order to adopt preventive strategies to attempt and reduce risk of developing DM and subsequent cardiovascular diseases. STRENGTHS & LIMITATIONS: To our knowledge, this is the first study evaluating the prevalence of unrecognized PreDM and the association of PreDM and ED severity in a real-life setting. Limitations are the retrospective nature of the cross-sectional study and the lack of haemodynamic parameters for every patient. CONCLUSIONS: 1 in 5 men seeking medical help for new-onset ED showed glucose values suggestive for unrecognized PreDM and +PreDM status was associated with worse hormonal and metabolic profiles, along with a higher risk of severe ED than -PreDM.

What More Can We Ask of Robotics?

The future of robotics relies heavily on the ongoing synergy between robotic surgery and artificial intelligence. To unlock their full potential, we should address issues such as accessibility, education, data privacy, and ethics.

Racial Disparities in Prostate Cancer Screening: The Role of Shared Decision Making.

INTRODUCTION: The 2018 U.S. Preventive Services Task Force recommendations endorsed shared decision making for men aged 55-69 years, encouraging consideration of patient race/ethnicity for prostate-specific antigen screening. This study aimed to assess whether a proxy shared decision-making variable modified the impact of race/ethnicity on the likelihood of prostate-specific antigen screening. METHODS: A cross-sectional analysis of men aged between 55 and 69 years, who responded to the prostate-specific antigen screening portions of the 2020 U.S.-based Behavioral Risk Factor Surveillance System survey, was performed between September and December 2022. Complex sample multivariable logistic regression models with an interaction term combining race and estimated shared decision making were used to test whether shared decision making modified the impact of race/ethnicity on screening. RESULTS: Of a weighted sample of 26.8 million men eligible for prostate-specific antigen screening, 25.7% (6.9 million) reported for prostate-specific antigen screening. In adjusted analysis, estimated shared decision making was a significant predictor of prostate-specific antigen screening (AOR=2.65, 95% CI=2.36, 2.98, p<0.001). The interaction between race/ethnicity and estimated shared decision making on the receipt of prostate-specific antigen screening was significant (pint=0.001). Among those who did not report estimated shared decision making, both non-Hispanic Black (OR=0.77, 95% CI=0.61, 0.97, p=0.026) and Hispanic (OR=0.51, 95% CI=0.39, 0.68, p<0.001) men were significantly less likely to undergo prostate-specific antigen screening than non-Hispanic White men. On the contrary, among respondents who reported estimated shared decision making, no race-based differences in prostate-specific antigen screening were found. CONCLUSIONS: Although much disparities research focuses on race-based differences in prostate-specific antigen screening, research on strategies to mitigate these disparities is needed. Shared decision making might attenuate the impact of race/ethnic disparities on the likelihood of prostate-specific antigen screening.

Development of a microultrasound-based nomogram to predict extra-prostatic extension in patients with prostate cancer undergoing robot-assisted radical prostatectomy.

OBJECTIVES: To develop a microultrasound-based nomogram including clinicopathological parameters and microultrasound findings to predict the presence of extra-prostatic extension and guide the grade of nerve-sparing. MATERIAL AND METHODS: All patients underwent microultrasound the day before robot-assisted radical prostatectomy. Variables significantly associated with extra-prostatic extension at univariable analysis were used to build the multivariable logistic model, and the regression coefficients were used to develop the nomogram. The model was subjected to 1000 bootstrap resamples for internal validation. The performance of the microultrasound-based model was evaluated using the area under the curve (AUC) of the receiver operating characteristic (ROC) curve, calibration plot, and decision curve analysis (DCA). RESULTS: Overall, 122/295 (41.4%) patients had a diagnosis of extra-prostatic extension on definitive pathology. Microultrasound correctly identify extra-prostatic extension in 84/122 (68.9%) cases showing a sensitivity and a specificity of 68.9% and 84.4%, with an AUC of 76.6%. After 1000 bootstrap resamples, the predictive accuracy of the microultrasound-based model was 85.9%. The calibration plot showed a satisfactory concordance between predicted probabilities and observed frequencies of extra-prostatic extension. The DCA showed a higher clinical net-benefit compared to the model including only clinical parameters. Considering a 4% cut-off, nerve-sparing was recommended in 173 (58.6%) patients and extra-prostatic extension was detected in 32 (18.5%) of them. CONCLUSION: We developed a microultrasound-based nomogram for the prediction of extra-prostatic extension that could aid in the decision whether to preserve or not neurovascular bundles. External validation and a direct comparison with mpMRI-based nomogram is crucial to corroborate our results.

Robot-Assisted Pyeloplasty with HUGO™ Robotic System: Initial Experience and Optimal Surgical Set-Up at a Tertiary Referral Robotic Center.

Background: In February 2021 Medtronic® (Minneapolis, MN) launched the HUGO™ Robot-Assisted Surgery (RAS) System in the global market. The aim of the current study is to describe the first case series and the optimal setup of robot-assisted pyeloplasty procedure, performed with HUGO RAS system in a tertiary referral robotic center. Methods: Data from consecutive patients who underwent robot-assisted pyeloplasty at Onze-Lieve-Vrouwziekenhuis Hospital (Aalst, Belgium) were recorded. Baseline characteristics, and perioperative and surgical outcomes were collected. Results: Overall, 10 robot-assisted pyeloplasties were performed (October 2022-September 2023). Based on our expertise, the following minor setting changes have been made, relative to the official setup guide: the endoscope port and, subsequently, the left and right-hand ports were positioned more laterally. Additionally, the reserve/4th port was placed more laterally and cranially, and adjusted the arm cart's tilt angle, reducing it from -30° to -15°. The median docking time was 8 (interquartile range [IQR]: 7.2-9.8) minutes, and the median active console time was 89.5 (80.0-95.8) minutes. No conversion to open/laparoscopic surgery or perioperative complications was encountered. A single technical problem was recorded in 1 (10%) procedure. Specifically, one arm was blocked, and the procedure was accomplished with three arms without compromising the procedure success. Conclusions: This study represents the first worldwide series of robot-assisted pyeloplasty performed with the HUGO RAS system and shows promising results. The procedure might be safely performed with this robotic platform achieving optimal perioperative outcomes.
