French translation of the Peyronie's disease questionnaire: A pilot study.

BACKGROUND: The Peyronie's Disease Questionnaire (PDQ) was designed to quantitatively assess the symptoms and psychosexual consequences of Peyronie's disease but has only been validated in four languages. The aim of the study was to provide a French translation of the PDQ, to make it available to the French-speaking urology community. METHODS: After a double translation of the PDQ from English into French, followed by a back translation by four expert translators, a conciliation process enabled the creation of the final French version. For each item, participants were asked to answer two sub-questions. The percentage of responses "I fully understood the question" to sub-question (a) constituted the validation criterion for the translation. RESULTS: The final French version was submitted to a series of 30 men with Peyronie's disease whose average age was 59 (±12) years. For each question, the comprehension rate was over 95%, and for 12/15 items it was 100%. For the remaining 3 items, men declared that they did not feel disturbed or bothered by the questions and none of the questions were misunderstood. CONCLUSION: This pilot study shows that our translation of the PDQ is valid and comprehensible by all participants, regardless of the age or level of education. This French version should be validated further in other French-speaking populations before final validation.

Cut-off time for surgery and prediction of orchiectomy in spermatic cord torsion: a retrospective multicentric study over 15 years.

PURPOSE: Cut-off time to avoid orchiectomy relies on small series of patients. The objective was to determine the cut-off time to avoid orchiectomy in torsion of the spermatic cord in a large cohort. METHODS: We performed a retrospective multicenter study (TORSAFUF cohort) of patients with suspected spermatic cord torsion between 2005 and 2019. All patients aged > 12 years who were suspected of having a torsion of the spermatic cord in 14 University Hospitals in France were included (n = 2986). Patients for whom data on pain duration were not available (n = 923) or for whom the final diagnosis was not torsion of the spermatic cord (n = 807) were excluded. The primary outcome was orchiectomy. The secondary outcomes were testicular survival time and the prediction of orchiectomy with the duration of pain. RESULTS: 1266 patients were included with an orchiectomy rate of 12% (150 patients). The mean age was 21.5 years old in the salvage group and 23.7 years old in the orchiectomy group (p = 0.01), respectively. The median time from the onset of pain to surgery was 5.5 (IQR = 5) hours in the salvage group and 51.1 (IQR = 70) hours in the orchiectomy group (p < 0.0001). The risk of orchiectomy increased after a time cut-off of 6 h 30. A delay of 15 h 30 in pain duration was found to predict orchiectomy (sensitivity: 0.81; specificity: 0.87). CONCLUSIONS: Pain duration can predict the probability of salvaging the testicles and performing orchiectomy. Rapid intervention should be recommended, regardless of the time elapsed from the onset of pain.

Torsion of the spermatic cord in adults: a multicenter experience in adults with surgical exploration for acute scrotal pain with suspected testicular torsion.

Acute scrotal pain (ASP) requiring surgical exploration is common in the pediatric population, but little has been reported on this subject with regard to the adult population. The aim of this study was to investigate the demographic and clinical characteristics and outcomes of scrotal explorations performed on adult patients. Patients over 21 years of age who underwent surgical exploration for ASP with suspected testicular torsion (TT) at 14 French hospitals between January 2005 and December 2019 were included in this study. The main outcome measures were demographic characteristics, pathology found during scrotal exploration, and perioperative outcomes. Logistic regression was used to perform univariate and multivariate analyses to identify predictors of TT. Data for 1329 men were analyzed. The median age was 30 (interquartile range [IQR]: 25-35; range: 21-89) years. Regarding the clinical examination, 867 (65.2%) patients presented with an elevation of the testicle, 613 (46.1%) patients with scrotal edema or erythema, and 211 (15.9%) patients with nausea or vomiting. Operative findings identified TT in only 684 (51.5%) patients, epididymo-orchitis in 112 (8.4%) patients, a tumor in 16 (1.2%) patients, and no causes in 475 (35.7%) patients. Orchiectomy for nonviable testes was required in 101 (7.6%) patients. In multivariate analysis, an elevation of the testicle, erythema/swelling, and the presence of nausea/vomiting were found to be associated with the occurrence of TT. Testicular torsion is not exclusive to children and adolescents, so must be considered in males of any age with acute scrotal findings. However, one-third of scrotal explorations in adults did not lead to a diagnosis.

Percutaneous Ablation Versus Surgical Resection for Local Recurrence Following Partial Nephrectomy for Renal Cell Cancer: A Propensity Score Analysis (REPART Study-UroCCR 71).

BACKGROUND: Data comparing percutaneous ablation (PCA) and surgical resection (SR) for an isolated local recurrence (LR) following partial nephrectomy (PN) for renal cell carcinoma (RCC) are lacking. OBJECTIVE: To examine the outcomes between PCA and SR for an isolated LR following PN for RCC. DESIGN, SETTING, AND PARTICIPANTS: Patients who underwent PN for RCC and developed an LR between 2013 and 2019 were included. An LR was defined as the appearance of a mass in contact with the resection bed or the development of a tumor in the same region of the homolateral kidney as the original site. INTERVENTION: PCA or SR. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: To achieve balance in baseline characteristics, we used inverse probability of treatment weighting (IPTW) based on propensity to receive treatment. Oncological outcomes, complications, and renal function were evaluated between groups using logistic, linear, and Cox proportional hazard regression models. RESULTS AND LIMITATIONS: A total of 81 patients with an isolated LR were included (PCA: 42; SR: 39). The median follow-up was 23 mo. After adjustment, excellent balance was achieved for the majority of propensity score variables. In IPTW analysis, PCA was associated with a lower risk of postoperative complications (odds ratio=0.22; p=0.006) and a smaller change in eGFR (beta=-16.18; p=0.001). There were no significant differences in the risk of disease recurrence (hazard ratio [HR]=0.72; p=0.61), new LR (HR=1.51; p=0.59), and distant metastasis (HR=0.19; p=0.09). Limitations include the sample size and unmeasured confounding factors. CONCLUSIONS: Our results suggest that PCA provides comparable oncological outcomes to repeat surgery with fewer complications and better renal function preservation for the management of an LR after PN. PATIENT SUMMARY: This report shows that percutaneous ablation can be used for treating a local recurrence of renal cell carcinoma after partial nephrectomy, without significantly compromising cancer control.

Contralateral Orchiopexy at the Time of Urgent Scrotal Exploration-Is It Safe? A Propensity Score Matched Analysis from the TORSAFUF Cohort.

PURPOSE: We evaluate the safety of immediate contralateral orchiopexy (ICLO) at the time of scrotal exploration for testicular torsion suspicion. MATERIALS AND METHODS: Patient data were retrieved from the TORSAFUF cohort project, which is a multicenter national study conducted at 14 academic French hospitals between 2005 and 2019. Each patient who underwent surgical exploration for testicular torsion suspicion was included. The primary study outcome was the safety of ICLO compared to ipsilateral scrotal exploration alone. The primary outcome of interest was the complication rate within 90 days of surgery. The end point was planned before data collection. RESULTS: Overall, 2,775 patients were included, of whom 1,554 (56%) underwent ICLO. After propensity score matching and multivariable analysis, ICLO was associated with a higher complication rate (OR 1.51, 95% CI 1.1-2.1, p=0.01), especially a higher rate of hematoma (OR 2.9, 95% CI 1.3-6.6, p=0.01), and delayed wound healing (OR 3.0, 95% CI 1.8-5.2, p <0.001). CONCLUSIONS: At the time of scrotal exploration for acute scrotum, ICLO was associated with an increased postoperative complication rate, with a particular increase in hematoma, and delayed wound healing. ICLO should not be performed systematically.

Financial development and energy poverty: global evidence.

This study aims to shed light on the determinants of energy poverty by examining the role of financial development. Notably, the study analyses the multidimensional effects of financial development (including two subsectors and three dimensions on five indicators of energy poverty). Various estimates are applied with a global sample of 65 economies, consisting of 36 low- and lower-middle-income economies and 29 upper-middle-income economies for 2002-2015. First, financial development can alleviate energy poverty. Second, the results are properly consistent across the two subsectors and three dimensions. Third, the two subsectors and three dimensions of financial development are found to reduce energy poverty in low- and lower-middle-income economies but have heteroscedastic effects in upper-middle-income economies.

Metformin inhibits growth of human glioblastoma cells and enhances therapeutic response.

High-grade gliomas, glioblastomas (GB), are refractory to conventional treatment combining surgery, chemotherapy, mainly temozolomide, and radiotherapy. This highlights an urgent need to develop novel therapies and increase the efficacy of radio/chemotherapy for these very aggressive and malignant brain tumors. Recently, tumor metabolism became an interesting potential therapeutic target in various cancers. Accordingly, combining drugs targeting cell metabolism with appropriate chemotherapeutic agents or radiotherapy has become attractive. In light of these perspectives, we were particularly interested in the anti-cancer properties of a biguanide molecule used for type 2 diabetes treatment, metformin. In our present work, we demonstrate that metformin decreases mitochondrial-dependent ATP production and oxygen consumption and increases lactate and glycolytic ATP production. We show that metformin induces decreased proliferation, cell cycle arrest, autophagy, apoptosis and cell death in vitro with a concomitant activation of AMPK, Redd1 and inhibition of the mTOR pathway. Cell sensitivity to metformin also depends on the genetic and mutational backgrounds of the different GB cells used in this study, particularly their PTEN status. Interestingly, knockdown of AMPK and Redd1 with siRNA partially, but incompletely, abrogates the induction of apoptosis by metformin suggesting both AMPK/Redd1-dependent and -independent effects. However, the primary determinant of the effect of metformin on cell growth is the genetic and mutational backgrounds of the glioma cells. We further demonstrate that metformin treatment in combination with temozolomide and/or irradiation induces a synergistic anti-tumoral response in glioma cell lines. Xenografts performed in nude mice demonstrate in vivo that metformin delays tumor growth. As current treatments for GB commonly fail to cure, the need for more effective therapeutic options is overwhelming. Based on these results, metformin could represent a potential enhancer of the cytotoxic effects of temozolomide and/or radiotherapy.
