RESUMEN
Overactive bladder (OAB) is a common yet under-reported condition affecting both men and women. Prevalence rises with age, but OAB can affect people of any age. It is associated with increased physical and mental health problems and may lead to social isolation and escalating care needs. It is a clinical diagnosis with symptoms of urgency, with or without urge incontinence and usually with urinary frequency and nocturia. Management includes conservative, medical and surgical treatments, which can significantly improve quality of life. This review aims to raise awareness of this under-reported condition and to empower health professionals to open discussions on bladder health with all those in their care.

PURPOSE: To assess the association of patient age with response to preoperative chemotherapy in patients with muscle-invasive bladder cancer (MIBC). MATERIALS AND METHODS: We analyzed data from 1105 patients with MIBC. Patients age was evaluated as continuous variable and stratified in quartiles. Pathologic objective response (pOR; ypT0-Ta-Tis-T1N0) and pathologic complete response (pCR; ypT0N0), as well survival outcomes were assessed. We used data of 395 patients from The Cancer Genome Atlas (TCGA) to investigate the prevalence of TCGA molecular subtypes and DNA damage repair (DDR) gene alterations according to patient age. RESULTS: pOR was achieved in 40% of patients. There was no difference in distribution of pOR or pCR between age quartiles. On univariable logistic regression analysis, patient age was not associated with pOR or pCR when evaluated as continuous variables or stratified in quartiles (all p > 0.3). Median follow-up was 18 months (IQR 6-37). On Cox regression and competing risk regression analyses, age was not associated with survival outcomes (all p > 0.05). In the TCGA cohort, patient with age ≤ 60 years has 7% less DDR gene mutations (p = 0.59). We found higher age distribution in patients with luminal (p < 0.001) and luminal infiltrated (p = 0.002) compared to those with luminal papillary subtype. CONCLUSIONS: While younger patients may have less mutational tumor burden, our analysis failed to show an association of age with response to preoperative chemotherapy or survival outcomes. Therefore, the use of preoperative chemotherapy should be considered regardless of patient age.

OBJECTIVE: Consensus statement by an international multispecialty trainers and trainees expert committee on guidelines for reporting of educational videos in laparoscopic surgery. SUMMARY OF BACKGROUND DATA: Instructive laparoscopy videos with appropriate exposition could be ideal for initial training in laparoscopic surgery, but there are no guidelines for video annotation or procedural educational and safety evaluation. METHODS: Delphi questionnaire of 45 statements prepared by a steering group and voted on over 2 rounds by committee members using an electronic survey tool. Committee selection design included representative surgical training experts worldwide across different laparoscopic specialties, including general surgery, lower and upper gastrointestinal surgery, gynecology and urology, and a proportion of aligned surgical trainees. RESULTS: All 33 committee members completed both the first and the second round of the Delphi questionnaire related to 7 major domains: Video Introduction/Authors' information; Patient Details; Procedure Description; Procedure Outcome; Associated Educational Content; Peer Review; and Use in Educational Curriculae. The 17 statements that did not reach at least 80% agreement after the first round were revised and returned into the second round. The committee consensus approved 37 statements to at least an 82% agreement. CONCLUSION: Consensus guidelines on how to report laparoscopic surgery videos for educational purposes have been developed. We anticipate that following our guidelines could help to improve video quality.These reporting guidelines may be useful as a standard for reviewing videos submitted for publication or conference presentation.

BACKGROUND: An estimated 5 billion people worldwide lack access to any surgical care, whilst surgical conditions account for 11-30% of the global burden of disease. Maximizing the effectiveness of surgical training is imperative to improve access to safe and essential surgical care on a global scale. Innovative methods of surgical training have been used in sub-Saharan Africa to attempt to improve the efficiency of training healthcare workers in surgery. Simulation training may have an important role in up-scaling and improving the efficiency of surgical training and has been widely used in SSA. Though not intended to be a systematic review, the role of simulation for teaching surgical skills in Sub-Saharan Africa was reviewed to assess the evidence for use and outcomes. METHODS: A systematic search strategy was used to retrieve relevant studies from electronic databases PubMed, Ovid, Medline for pertinent articles published until August 2016. Studies that reported the use of simulation-based training for surgery in Africa were included. RESULTS: In all, 19 articles were included. A variety of innovative surgical training methods using simulation techniques were identified. Few studies reported any outcome data. Compared to the volume of surgical training initiatives that are known to take place in SSA, there is very limited good quality published evidence for the use of simulation training in this context. CONCLUSIONS: Simulation training presents an excellent modality to enhance and improve both volume and access to high quality surgical skills training, alongside other learning domains. There is a desperate need to meticulously evaluate the appropriateness and effectiveness of simulation training in SSA, where simulation training could have a large potential beneficial impact. Training programs should attempt to assess and report learner outcomes.

OBJECTIVES: To describe the implementation phase of a robot-assisted radical cystectomy (RARC) programme including side-effect profiles and impact on length of stay (LOS). PATIENTS AND METHODS: In all, 114 consecutive patients (82% male) underwent RARC and urinary diversion between April 2013 and December 2015 [ileal conduit (97 patients) and orthotopic neobladder (17)]. Surgery was performed by two surgeons within a designated regional cancer centre. No exclusion criteria were applied. All patients were managed on the Exeter Enhanced Recovery Pathway (ERP) in a unit where embedded enhanced recovery practice was already established. Data were collected prospectively on the national cystectomy registry - the British Association of Urological Surgeons (BAUS) Complex Operations Dataset. RESULTS: RARC was technically feasible in all but one case. The mean operating time was 3-5 h with an overall transfusion rate of 8.8%. There were higher-grade complications (Clavien-Dindo grade III-IV) in 18.4% of patients, with a 30-day mortality rate of 0.9%. The median (range) LOS after RARC was 7 (3-68) days, with a re-admission rate of 18.4%. CONCLUSIONS: The present series shows that RARC can be safely implemented in a unit experienced in robot-assisted surgery (RAS). Case-selection in this setting is not deemed necessary. There are benefits in terms of lower transfusion rates and reduced LOS. The side-effect profile appears to differ from that of open RC, and despite the fact that complication rate is equivalent; 'technical' complications are over-represented in the RAS group. As such, they should improve with experience, recognition, and modification of surgical technique. ERPs can be safely applied to all patients undergoing RARC to maximise the benefits of minimally invasive surgery.

Male adult circumcision (MC) has been shown to reduce the risk of HIV transmission in men by 50-60 %. An upscaling in the training of providers to perform circumcision is necessary to meet demand since MC is a key component of essential surgery in the context of universal health coverage. We piloted a low-cost, high-fidelity model for training adult circumcision. Multi-centre, multinational data were collected on 74 trainees and clinicians (trainers) in sub-Saharan Africa. Both trainers and trainees gave excellent feedback for the model (content and face validity). The simulated model enables a safe and realistic simulation experience to perform MC. The model is quick to set up and easily transportable to multiple teaching sites.

INTRODUCTION: The neutrophil-to-lymphocyte ratio (NLR) is an attractive marker because it is derived from routine bloodwork. NLR has shown promise as a prognostic factor in muscle invasive bladder cancer (MIBC) but its value in patients receiving neoadjuvant chemotherapy (NAC) before radical cystectomy (RC) is not yet established. Since NLR is related to an oncogenic environment and poor antitumor host response, we hypothesized that a high NLR would be associated with a poor response to NAC and would remain a poor prognostic indicator in patients receiving NAC. METHODS: A retrospective analysis was performed on patients with nonmetastatic MIBC (cT2-4aN0M0) who received NAC prior to RC between 2000 and 2013 at 1 of 19 centers across Europe and North America. The pre-NAC NLR was used to split patients into a low (NLR ≤ 3) and high (NLR > 3) group. Demographic and clinical parameters were compared between the groups using Student's t test, chi-squared, or Fisher's exact test. Putative risk factors for disease-specific and overall survival were analyzed using Cox regression, while predictors of response to NAC (defined as absence of MIBC in RC specimen) were investigated using logistic regression. RESULTS: Data were available for 340 patients (199 NLR ≤ 3, 141 NLR > 3). Other than age and rate of lymphovascular invasion, demographic and pretreatment characteristics did not differ significantly. More patients in the NLR > 3 group had residual MIBC after NAC than the NLR ≤ 3 group (70.8% vs. 58.3%, Pâ¯=â¯0.049). NLR was the only significant predictor of response (odds ratio: 0.36, Pâ¯=â¯0.003) in logistic regression. NLR was a significant risk factor for both disease-specific (hazard ratio (HR): 2.4, Pâ¯=â¯0.006) and overall survival (HR:1.8, Pâ¯=â¯0.02). CONCLUSION: NLR > 3 was associated with a decreased response to NAC and shorter disease-specific and overall survival. This suggests that NLR is a simple tool that can aid in MIBC risk stratification in clinical practice.

OBJECTIVE: To assess the effect of patient's sex on response to neoadjuvant chemotherapy (NAC) in patients with clinically nonmetastatic muscle-invasive bladder cancer (MIBC). METHODS: Complete pathologic response, defined as ypT0N0 at radical cystectomy, and downstaging were evaluated using sex-adjusted univariable and multivariable logistic regression modeling. We used interaction terms to account for age of menopause and smoking status. The association of sex with overall survival and cancer-specific survival was evaluated using Cox regression analyses. RESULTS: A total of 1,031 patients were included in the analysis, 227 (22%) of whom were female. Female patients had a higher rate of extravesical disease extension (Pâ¯=â¯0.01). After the administration of NAC, ypT stage was equally distributed between sexes (Pâ¯=â¯0.39). On multivariable logistic regression analyses, there was no difference between the sexes or age of menopause with regards to ypT0N0 rates or downstaging (all P > 0.5). On Cox regression analyses, sex was associated with neither overall survival (hazard ratio 1.04, 95% confidence interval 0.75-1.45, Pâ¯=â¯0.81) nor cancer-specific survival (hazard ratio 1.06, 95% confidence interval 0.71-1.58, Pâ¯=â¯0.77). CONCLUSION: Our study generates the hypothesis that NAC equalizes the preoperative disparity in pathologic stage between males and females suggesting a possible differential response between sexes. This might be the explanation underlying the comparable survival outcomes between sexes despite females presenting with more advanced tumor stage.

BACKGROUND: The efficacy of neoadjuvant chemotherapy (NAC) for muscle-invasive bladder cancer (BCa) was established primarily with methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC), with complete response rates (pT0) as high as 38%. However, because of the comparable efficacy with better tolerability of gemcitabine and cisplatin (GC) in patients with metastatic disease, GC has become the most commonly used regimen in the neoadjuvant setting. OBJECTIVE: We aimed to assess real-world pathologic response rates to NAC with different regimens in a large, multicenter cohort. DESIGN, SETTING, AND PARTICIPANTS: Data were collected retrospectively at 19 centers on patients with clinical cT2-4aN0M0 urothelial carcinoma of the bladder who received at least three cycles of NAC, followed by radical cystectomy (RC), between 2000 and 2013. INTERVENTION: NAC and RC. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary outcome was pathologic stage at cystectomy. Univariable and multivariable analyses were used to determine factors predictive of pT0N0 and ≤pT1N0 stages. RESULTS AND LIMITATIONS: Data were collected on 935 patients who met inclusion criteria. GC was used in the majority of the patients (n=602; 64.4%), followed by MVAC (n=183; 19.6%) and other regimens (n=144; 15.4%). The rates of pT0N0 and ≤pT1N0 pathologic response were 22.7% and 40.8%, respectively. The rate of pT0N0 disease for patients receiving GC was 23.9%, compared with 24.5% for MVAC (p=0.2). There was no difference between MVAC and GC in pT0N0 on multivariable analysis (odds ratio: 0.89 [95% confidence interval, 0.61-1.34]; p=0.6). CONCLUSIONS: Response rates to NAC were lower than those reported in prospective randomized trials, and we did not discern a difference between MVAC and GC. Without any evidence from randomized prospective trials, the best NAC regimen for invasive BCa remains to be determined. PATIENT SUMMARY: There was no apparent difference in the response rates to the two most common presurgical chemotherapy regimens for patients with bladder cancer.
