Vaginal cuff recurrence after radical cystectomy: an under - studied site of bladder cancer relapse
Vaginal cuff recurrence of tumor following radical cystectomy is a rare site of disease recurrence, however it has never been specifically studied. The aim of the study is to evaluate incidence, risk factors, and long-term oncologic outcomes of vaginal cuff recurrence in a cohort of female patients treated with radical cystectomy for invasive urothelial carcinoma of the bladder
Nadir creatinine as a predictor of renal outcomes in PUVs: A systematic review and meta-analysis
Background: Posterior urethral valves (PUVs) represent the most severe pediatric obstructive uropathy, responsible for chronic renal failure in up to 65% of cases and progression to end-stage kidney disease (ESKD) in about 8%–21% of patients. Unfortunately, renal outcomes have poorly improved over time. The key point is to identify patients at risk; thus, several prenatal and postnatal prognostic factors have been analyzed to improve clinical outcomes. Postnatal nadir creatinine seems to accurately predict long-term renal prognosis, but there is no definitive evidence to support this finding. Objective: We performed a systematic review with meta-analysis to analyze the predictive value of nadir creatinine on long-term renal function in infants with PUVs. Methods: We conducted this systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. PubMed and Cochrane Library were systematically searched for studies published from January 2008 to June 2022. All the articles were checked independently by two reviewers in two steps. Results: A total of 24 articles were screened, and 13 were included for data extraction. Data from 1,731 patients with PUVs were analyzed, with a mean follow-up of 5.5 years; of these, on average, 37.9% developed chronic kidney disease (CKD) and 13.6% developed ESKD. All the articles evaluated nadir creatinine as a predictor of CKD, most using a level of 1 mg/dL, with statistical significance at the 5% level. The relative risk of developing CKD in patients with creatinine values higher than the nadir cutoff considered was 7.69 (95% CI: 2.35–25.17, I2 = 92.20%, p < 0.001). Conclusions: Nadir creatinine is the best prognostic factor for long-term renal function in patients affected by PUV. A value above the cutoff of 1 mg/dL should be considered a significant predictor for the risk of CKD and ESKD. Further studies are needed to define different nadir creatinine cutoffs for better stratification of the different CKD stages and for the development of reliable scores, which include the association of several variables
Effect of Level of Urology Training on Gleason Score and Prostate Volume Estimation Agreement between Transrectal Ultrasound Guided Biopsy and Radical Prostatectomy Specimen
Introduction Transrectal ultrasound guided prostate biopsy may be performed by operators with various levels of training. Little is known about the impact of training level on biopsy results. We evaluated the effect of training level on the accuracy of transrectal ultrasound guided prostate biopsy findings. Methods We retrospectively reviewed 500 consecutive patients who underwent transrectal ultrasound guided prostate biopsy and subsequent radical prostatectomy. Transrectal ultrasound operators were stratified based on level of training as junior, senior, chief, fellow or staff. Linear regression was performed to analyze the effect of training level on volume estimates. A weighted Kappa statistic evaluated agreement between biopsy and pathological Gleason scores while an adjusted cumulative logistic regression model analyzed the effects of training level. Results A total of 482 patients were included in the final analysis. Transrectal ultrasound guided biopsy was performed by staff in 78 (16%) patients, by fellows in 18 (4%), chief residents in 48 (10%), senior residents in 126 (26%) and junior residents in 212 (44%). There was no significant difference between transrectal ultrasound and radical prostatectomy specimen volume estimates among the training levels. Level of training was not significantly associated with pathological features, including Gleason score, primary Gleason grade, highest single Gleason grade and estimated tumor volume. Study limitations include the retrospective design and the variability among members of the same group. Conclusions Agreement between biopsy and pathological Gleason scores is high for all levels of training. Training level has no impact on prostate volume estimations or the prediction of pathological features
Minimally invasive urologic surgery is safe during COVID-19: experience from two high-volume centers in Italy
Potential risks of COVID-19 spread during minimally invasive procedures caused several concerns among surgeons, despite the lack of high-level evidence. Urological robotic and laparoscopic surgery is performed in elective setting in almost all occasions, thus allowing adequate planning and stratification. Two high-volume urological centers in Italy performed 77 robotic and laparoscopic surgeries during the \u201clockdown\u201d period and adopted various strategies to prevent contamination. First of all, all patients were tested negative with nasopharyngeal swab before the surgical intervention. Patients and personnel were provided adequate personal protective equipment and intraoperative strategies to prevent smoke formation and pneumoperitoneum spread were adopted. No patients nor staff members tested positive for COVID-19 during a 15-day follow-up period. In conclusion, minimally invasive urologic surgery can be safely performed during the pandemic period with adequate planning. We believe that renouncing the benefits of it would be counterproductive, especially in a scenario of long-lasting cohabitation with the virus
The impact of COVID-19 pandemic on pornography habits: a global analysis of Google Trends
As the COVID-19 spread globally, social distancing, self-isolation/quarantine, and national lockdowns have become crucial to control the pandemic. However, these measures may also lead to increases in social isolation, loneliness, and stress, which can alter the consumption of pornography habits. The aim of the study was thus to explore the interest pattern in pornography and coronavirus-themed pornography during the COVID-19 outbreak. Google Trends\uae was employed to determine the most popular porn websites (Porn, XNXX, PornHub, xVideos, and xHamster), and coronavirus-themed pornography worldwide and in six nations with different COVID-19 outbreak and self-isolation recommendations. We analyzed every search trend on Google\uae from January 9, 2020 to May 25, 2020 using \u201cjoint point regression analysis\u201d. Comparisons of week relative search volume (WRSV) and temporal patterns were analyzed to assess the change of interest in search terms during nations lockdowns. Paired t-test was used to compare WRSV values among the porn websites during the national lockdowns and the equivalent timespan of the weeks in the previous 4 years. The research trend of almost every keyword increased with significant inflection points for those nations with a straight \u201cstay at home orders\u201d (China, Italy, Spain, and France). \u201cPornHub\u201d and \u201cPorn\u201d showed the highest increase of interest worldwide with an average weekend percentage change (AWPC) of 4.9 and 3.8, respectively. The mean WRSV for keywords in USA and Sweden did not show a similar increase as the other nations. The WRSV percentage change with the historical data had a peak during the straight nations\u2019 lockdowns (p < 0.01). All the nations had a significant increase in WRSV coronavirus-themed pornography for each keyword (p < 0.01) with an AWPC, ranging worldwide between 18.5 and 61.8 (p < 0.01), after the beginning of self-quarantine. As strengths this study uses a big data technology to collect worldwide trend of interest, however, data are anonymous and do not allow analysis of subpopulation groups. In conclusion, we demonstrated an increased interest in pornography and coronavirus-themed pornography after the outbreak of COVID-19 in nations with a straight \u201cstay at home orders\u201d

Scopo del lavoro
Some reports suggested that nephron sparing surgery (NSS) may better protect against other-cause mortality
(OCM) when compared with radical nephrectomy (RN) in patients with small renal masses. However,
the majority of those studies could not adjust their results for potential selection bias secondary to clinical
baseline characteristics of patients. In the current study, we aimed to test the effect of treatment type (NSS
vs. RN) after accounting for clinical characteristics, comorbidities and individual cardiovascular risk.
Materiali e metodi
A multi-institutional collaboration among four European Tertiary Care Centers allowed collecting 2685
patients with a clinical T1a-T1b N0 M0 renal mass. Patients underwent RN (n=1059, 39.4%) or NSS
(n=1626, 60.6%) and showed normal estimated glomerular filtration rates (eGFR) before surgery (defined as
a pre-operative eGFR 6560 milliliters per minute per 1.73 m2). Descriptive, univariable and multivariable Cox
regression analyses were used to predict the risk of OCM. To adjust for inherent baseline differences among
patients, we included as covariates: age, clinical tumor size, gender, presence of hypertension at diagnosis,
baseline Charlson comorbidity index (CCI), body mass index and smoker status.
Risultati
Mean follow up period was 76 months (median 61). Mean patient age resulted 60 years (median 62). Mean
body mass index resulted 25 kg/m2. Overall, 37.2% and 9.4% of the patients had hypertension or diabetes,
respectively. CCI resulted 0-1 in 73.2% of the patients. The 5- and 10-yr OCM rates after nephrectomy
were 5.2% and 13.2% for NSS versus 7.4% and 15.1% for RN, respectively (p=0.3). At multivariable
analyses, patients who underwent PN showed similar risk to die for OCM compared with their RN-treated
counterparts (hazard ratio [HR]: 0.77; 95% confidence interval, 0.48-1.25; p=0.3). Increasing age (HR: 1.12
