Abstract
Objective To assess if there is a preferable intervention between retrograde ureteral stent (RUS) and percutaneous nephrostomy (PCN) tube, in cases of upper urinary tract stone obstruction with complications requiring urgent drainage, by evaluating outcomes regarding urinary symptoms, quality of life (QoL), spontaneous stone passage, and length of hospital stays, since there is no literature stating the superiority of one modality over the other. Methods We searched MEDLINE and other sources for relevant articles in June 2019 without any date restrictions or filters applied. The selection was done first by the title and abstract screening and then by full-text assessment for eligibility. Only randomized controlled trials or cohort studies in patients with hydronephrosis secondary to obstructive urolithiasis that presented comparative data between PCN and RUS placement concerning at least one of the defined outcome measures were included. Lastly, MEDLINE database and PubMed platform were screened again using the same terms, from June 2019 until November 2022. Results Of 556 initial articles, seven were included in this review. Most works were considered of moderate-to-high quality. Three studies regarding QoL showed a tendency against stenting, even though only one demonstrated statistically significant negative impact on overall health state. Two works reported significantly more post-intervention urinary symptoms in stenting patients. One article found that PCN is a significant predictor of spontaneous stone passage, when adjusted for stone size and location. Findings on length of hospital stays were not consistent among articles. Conclusion PCN appears to be the intervention better tolerated, with less impact on the patient's perceived QoL and less post-operative urinary symptoms, in comparison with RUS. Nevertheless, further studies with larger samples and a randomized controlled design are suggested.

Abstract
This paper introduces the "SurgT: Surgical Tracking" challenge which was organized in conjunction with the 25th International Conference on Medical Image Computing and Computer-Assisted Intervention (MICCAI 2022). There were two purposes for the creation of this challenge: (1) the establishment of the first standardized benchmark for the research community to assess soft-tissue trackers; and (2) to encourage the development of unsupervised deep learning methods, given the lack of annotated data in surgery. A dataset of 157 stereo endoscopic videos from 20 clinical cases, along with stereo camera calibration parameters, have been provided. Participants were assigned the task of developing algorithms to track the movement of soft tissues, represented by bounding boxes, in stereo endoscopic videos. At the end of the challenge, the developed methods were assessed on a previously hidden test subset. This assessment uses benchmarking metrics that were purposely developed for this challenge, to verify the efficacy of unsupervised deep learning algorithms in tracking soft-tissue. The metric used for ranking the methods was the Expected Average Overlap (EAO) score, which measures the average overlap between a tracker's and the ground truth bounding boxes. Coming first in the challenge was the deep learning submission by ICVS-2Ai with a superior EAO score of 0.617. This method employs ARFlow to estimate unsupervised dense optical flow from cropped images, using photometric and regularization losses. Second, Jmees with an EAO of 0.583, uses deep learning for surgical tool segmentation on top of a non-deep learning baseline method: CSRT. CSRT by itself scores a similar EAO of 0.563. The results from this challenge show that currently, non-deep learning methods are still competitive. The dataset and benchmarking tool created for this challenge have been made publicly available at https://surgt.grand-challenge.org/. This challenge is expected to contribute to the development of autonomous robotic surgery and other digital surgical technologies.

Abstract
BACKGROUND AND OBJECTIVES Patients with pulmonary arterial hypertension (PAH) require risk assessments for prognosis and appropriate therapy. These assessments need to be improved by incorporating clinical and laboratory data such as the analysis of the right ventricle. We aim to establish echocardiographic morphometric data of the right ventricle and its relationship with the left ventricle, to estimate the hemodynamic severity of precapillary pulmonary hypertension (PHprecapillary). METHODS This cohort, prospective, observational, and cross-sectional study included 41 consecutive patients with PHprecapillary using echocardiographic study and cardiac catheterization. RESULTS Patients' mean age was 44.0±16.4 years, and 37 were women (90.2%). Idiopathic PAH was diagnosed in 18 patients (43.9%). The World Health Organization/New York Association functional class was III or IV in 31 patients (75.6%). The ratio of the right to left ventricles (RV/LV) echocardiographic diastolic diameters was associated with pulmonary arterial pressures in cardiac catheterization, with the best cutoff per receiver operating characteristic curve being 0.8 for systolic pressure (sensitivity 90.0%, specificity 78.3%, area under the curve [AUC] 0.882) and mean pressure (sensitivity 60.0%, specificity 95.7%, AUC 0.823). Spearman's correlation (R) of RV/LV echocardiographic ratio and the hemodynamic variables was significant for systolic pressure (R = 0.7015, p < 0.0001), mean pressure (R = 0.6332, p < 0.0001), transpulmonary pressure gradient (R = 0.6524, p < 0.0001), pulmonary vascular resistance (R = 0.6076, p = 0.0021), and pulmonary vascular resistance index (R = 0.6229, p = 0.0014). CONCLUSION The ratio of RV/LV echocardiographic diastolic diameters contribute to the estimates the hemodynamic severity of precapillary pulmonary hypertension. The best cutoff for this assessment was RV/LV of 0.8.

Abstract
Formalizing surgical activities as triplets of the used instruments, actions performed, and target anatomies is becoming a gold standard approach for surgical activity modeling. The benefit is that this formalization helps to obtain a more detailed understanding of tool-tissue interaction which can be used to develop better Artificial Intelligence assistance for image-guided surgery. Earlier efforts and the CholecTriplet challenge introduced in 2021 have put together techniques aimed at recognizing these triplets from surgical footage. Estimating also the spatial locations of the triplets would offer a more precise intraoperative context-aware decision support for computer-assisted intervention. This paper presents the CholecTriplet2022 challenge, which extends surgical action triplet modeling from recognition to detection. It includes weakly-supervised bounding box localization of every visible surgical instrument (or tool), as the key actors, and the modeling of each tool-activity in the form of ‹instrument, verb, target› triplet. The paper describes a baseline method and 10 new deep learning algorithms presented at the challenge to solve the task. It also provides thorough methodological comparisons of the methods, an in-depth analysis of the obtained results across multiple metrics, visual and procedural challenges; their significance, and useful insights for future research directions and applications in surgery.

Abstract
Radical prostatectomy is a highly successful treatment for prostate cancer, among the most prevalent manifestations of the illness. Damage of the cavernous nerve (CN) during prostatectomy is the main cause of postoperative erectile dysfunction (ED). In this study, the capability of a personalized bioactive fibrous membrane to regenerate injured CN was investigated. The fibrous membrane bioactivity is conferred by the selectively bound nerve growth factor (NGF) present in the rat urine. In a rat model of bilateral CN crush, the implanted bioactive fibrous membrane induces CN regeneration and restoration of erectile function, showing a significantly increased number of smooth muscle cells and content of endothelial and neuronal nitric oxide synthases (eNOS; nNOS). In addition, the bioactive fibrous membrane promotes nerve regeneration by increasing the number of myelinated axons and nNOS-positive cells, therefore reversing the CN fibrosis found in untreated rats or rats treated with a bare fibrous membrane. Therefore, this personalized regenerative strategy could overcome the recognized drawbacks of currently available treatments for CN injuries. It may constitute an effective treatment for prostate cancer patients suffering from ED after being subject to radical prostatectomy. STATEMENT OF SIGNIFICANCE: The present work introduces a unique strategy to address post-surgical ED resulting from CN injury during pelvic surgery (e.g., radical prostatectomy, radical cystoprostatectomy, abdominoperineal resection). It comprises a bioactive and cell-free fibrous implant, customized to enhance CN recovery. Pre-clinical results in a rat model of bilateral CN crush demonstrated that the bioactive fibrous implant can effectively heal injured CN, and restore penile structure and function. This implant selectively binds NGF from patient fluids (i.e. urine) due to its functionalized surface and high surface area. Moreover, its local implantation reduces adverse side effects. This tailored regenerative approach has the potential to revolutionize the treatment of ED in prostate cancer patients following radical prostatectomy, overcoming current treatment limitations.

Abstract
Training in surgery is essential for surgeons to develop skill and dexterity. Physical training phantoms provide excellent haptic feedback and tissue properties for stitching and operating with authentic instruments and are easily available. However, they lack realistic traits and fail to reflect the complex environment of a surgical scene. Generative Adversarial Networks can be used for image-to-image translation, addressing the lack of realism in physical phantoms, by mapping patterns from the intraoperative domain onto the video stream captured during training with these surgical simulators. This work aims to achieve a successful I2I translation, from intra-operatory mitral valve surgery images onto a surgical simulator, using the CycleGAN model. Different experiments are performed - comparing the Mean Square Error Loss with the Binary Cross Entropy Loss; validating the Fréchet Inception Distance as a training and image quality metric; and studying the impact of input variability on the model performance. Differences between MSE and BCE are modest, with MSE being marginally more robust. The FID score proves to be very useful in identifying the best training epochs for the CycleGAN I2I translation architecture. Carefully selecting the input images can have a great impact in the end results. Using less style variability and input images with good feature details and clearly defined characteristics enables the network to achieve better results.Clinical Relevance- This work further contributes for the domain of realistic surgical training, successfully generating fake intra operatory images from a surgical simulator of the cardiac mitral valve.

Abstract
Introduction This study aimed to compare trainees’ laparoscopic performance concerning the peg-transfer (PT) and needle-guidance (NG) exercises after watching the original European Basic Laparoscopic Urologic Skills (E-BLUS) video or after watching a video-mentored tutorial (VMT) with ‘tips and tricks’, narration and didactic illustrations. Material and methods An experimental, unblinded, parallel, 2-intervention, 2-period randomized trial with an allocation ratio of 1:1 was conducted. Forty-two participants were randomized into 2 groups. Prior to task initiation, Group 1 watched the VMT in both trials and Group 2 watched, firstly, the original E-BLUS examination video and, in the second trial, the VMT. Each participant performed 2 trials for each exercise. Outcome measures were task time and total number of errors. Results In the first period, participants who visualized the PT and NG VMT had fewer errors than participants who visualized the E-BLUS video (p = 0.001 and p = 0.014, respectively). In the second period, after watching the VMT, a decrease in the total number of errors in PT and NG exercises was observed in the participants who previously watched the E-BLUS video (p = 0.001 and p = 0.002, respectively). In the second period, a decrease in median task time was observed for Group 1 and 2 after watching the PT VMT (p ≤0.001 and p = 0.003, respectively) and NG VMT (p = 0.005 and p = 0.01, respectively). Conclusions The use of VMT can lead to a smaller number of errors and, if coupled with deliberate practice, could lead to a shorter task time in exercise performance among participants with no previous laparoscopic experience.

Abstract
BACKGROUND The aim of the study was to test the effect of active surveillance (AS) versus primary intervention (PI) on overall mortality (OM) in elderly patients diagnosed with SRM. METHODS Elderly patients (75 years or older) diagnosed with SRMs (<4 cm) and treated with either PI (i.e. partial nephrectomy or kidney ablation) or AS between 2009 and 2018 were abstracted from the renal surgery in the elderly (RESURGE) and Delayed Intervention and Surveillance for small Renal Masses (DISSRM) datasets, respectively. OM rates were estimated among groups with Kaplan Meier method and Cox proportional hazards regression models after applying inverse probability of treatment weighting (IPTW). Multivariable logistic regression model was used to estimate IPTW. Covariates of interest were those unbalanced and/or significantly correlated with the treatment choice or with OM. RESULTS A total of 483 patients were included; 121 (25.1%) underwent AS. Sixty patients (12.4%) died. Overall, 6.7% of all deaths were related to cancer. IPTW-Kaplan Meier curves showed a 5-year overall survival rates of 70.0±3.5% and 73.2±4.8% in AS and PI groups, respectively (IPTW-Log-rank P value=0.308). IPTW-Cox regression model did not show meaningfully increased OM rates in AS group (HR: 1.31, 95% CI: 0.69-2.49). CONCLUSIONS AS represents an appealing treatment option for very elderly patients presenting with SRM, as it avoids the risks of a PI while not compromising the survival outcomes of these patients.

Abstract
The aim of the study was to perform a comprehensive investigation of clinical outcomes of robot-assisted partial nephrectomy (RAPN) or laparoscopic partial nephrectomy (LPN) in elderly patients presenting with a renal mass. The REnal SURGery in Elderly (RESURGE) collaborative database was queried to identify patients aged 75 or older diagnosed with cT1-2 renal mass and treated with RAPN or LPN. Study outcomes were: overall complications (OC); warm ischemia time (WIT) and 6-month estimated glomerular filtration rate (eGFR); positive surgical margins (PSM), disease recurrence (REC), cancer-specific mortality (CSM) and other-cause mortality (OCM). Descriptive statistics, Kaplan-Meier, smoothed Poisson plots and logistic and linear regression models (MVA) were used. Overall, 216 patients were included in this analysis. OC rate was 34%, most of them being of low Clavien grade. Median WIT was 17 minutes and median 6-month eGFR was 54 ml/min/1.73 m2. PSM rate was 5%. After a median follow-up of 20 months, the 5-year rates of REC, CSM and OCM were 4, 4 and 5%, respectively. At MVA predicting perioperative morbidity, RAPN relative to LPN (odds ratio [OR] 0.33; p <0.0001) was associated with lower OC rate. At MVA predicting functional outcomes, RAPN relative to LPN was associated with shorter WIT (estimate [EST] -4.09; p <0.0001), and with higher 6-month eGFR (EST 6.03; p = 0.01). In appropriately selected patients with small renal masses, minimally-invasive PN is associated with acceptable perioperative outcomes. The use of a robotic approach over a standard laparoscopic approach can be advantageous with respect to clinically relevant outcomes, and it should be preferred when available.

Abstract
BACKGROUND Pi-score (Performance Improvement score) has been proven to be reliable to measure performance improvement during E-BLUS hands-on training sessions. Our study is aimed to adapt and test the score to EST s1 (Endoscopic Stone Treatment step 1) protocol, in consideration of its worldwide adoption for practical training. METHODS The Pi-score algorithm considers time measurement and number of errors from two different repetitions (first and fifth) of the same training task and compares them to the relative task goals, to produce an objective score. Data were obtained from the first edition of 'ART in Flexible Course', during 4 courses in Barcelona and Milan. Collected data were independently analysed by the experts for Pi assessment. Their scores were compared for inter-rater reliability. The average scores from all tutors were then compared to the PI-score provided by our algorithm for each participant, in order to verify their statistical correlation. Kappa Statistics was used for comparison analysis. RESULTS 16 Hands-on Training expert tutors and 47 3rd year residents in Urology were involved. Concordance found between the 16 proctors' scores was the following: Task1=0.30 ("fair"); Task2=0.18 ("slight"); Task3=0.10 ("slight"); Task4=0.20, ("slight"). Concordance between Pi-score results and proctor average scores per-participant was the following: Task1=0.74 ("substantial"); Task2=0.71 ("substantial"); Task3=0.46 ("moderate"); Task4=0.49 ("moderate"). CONCLUSIONS Our exploratory study demonstrates that Pi-score can be effectively adapted to EST s1. Our algorithm successfully provided an objective score that equals the average performance improvement scores assigned by of a cohort of experts, in relation to a small amount of training attempts.

Abstract
BACKGROUND Studies into the mental health of firefighters have primarily focussed on individual factors (e.g. biological and psychological factors). Little is known about how exposure to traumatic events and psychosocial and organizational work factors influence firefighters' mental health despite the evidence that these are important for employee health. AIMS To study job demands, job control, social support and operational trauma as predictors of firefighters' psychiatric morbidity, and whether job control and social support moderate these relationships. METHODS Participants were drawn from a longitudinal cohort study of firefighters in Brazil. Portuguese-language variants of the Self-Report Questionnaire (SRQ-20) and Traumatic Events List for Emergency Professionals measured psychiatric morbidity and exposure to traumatic events. Job demands, job control and social support were measured by the Job Stress Scale. Hierarchical regressions were run controlling for socio-demographics and previous psychiatric morbidity. Subsequent regression steps first included the proposed predictors followed by their interactions. RESULTS Thirteen per cent of the sample (n = 40/312) met the caseness criteria indicating psychiatric morbidity. Operational trauma, job demands, job control and social support predicted psychiatric morbidity. Both job control and social support functioned as moderators and where these moderators were high, the job demands and psychiatric morbidity relationships were weaker. CONCLUSIONS These findings show that psychosocial factors and operational trauma predict firefighters' psychiatric morbidity. Crucially, the results that improving social support and job control could mitigate the detrimental influence of job demands highlight the need for more research and practice towards organizational-level interventions.

Abstract
BACKGROUND Percutaneous access to the renal pelvis still remains the most difficult step before nephrolitholapaxy (PCNL). New imaging techniques, such as 3D imaging and various navigation instruments such as electromagnetic, sonographic, CT-controlled and marker-based/iPAD try to simplify this step and reduce complications. OBJECTIVES In this review, various new techniques for puncturing the renal collecting system are presented and their advantages and disadvantages are evaluated. MATERIALS AND METHODS A systematic literature search was carried out in MEDLINE, whereby only puncture techniques that have already been evaluated in clinical studies were included. RESULTS Five different navigation methods for puncturing the renal pelvis before PCNL were found. CONCLUSION Intraoperative navigation can be useful when puncturing the collecting system. The combination of ultrasound and fluoroscopy currently remains the gold standard. However, there is still a need for further, primarily clinical, prospective studies to determine which new imaging technology and navigation systems will prevail and thus facilitate the access route to the kidney, especially in the case of special anatomical conditions.

Abstract
BACKGROUND Percutaneous nephrolithotomy (PCNL) is the gold-standard for treatment of renal stones larger than 20 mm. Traditionally, a nephrostomy tube (NT) is placed, causing discomfort and prolonged hospitalization but some surgeons prefer the tubeless technique (TL). Simultaneously, the effectiveness of ureteral stents after PNCL is doubtful. We investigated the safety of the TL technique as well as that of the single loop (SL) over double loop (DL) stents. METHODS Three hundred and twenty-one individuals submitted to PCNL in a single center were retrospectively reviewed. Statistical analysis was performed to compare procedures regarding safety and effectiveness (stone size, residual stones, operative time, peri- and post-operative complications, need for blood transfusion and length of hospital stay) between two groups regarding presence or absence of NT placement (NT [N.=198] vs. TL [N.=123]); and according to the type of stent used (SL [N.=74] vs. DL [N.=247]). RESULTS NT was associated with a higher complications rate compared to the TL (30.3% and 13%, respectively; P=0.001) and longer hospitalization (4 vs. 2 days; P=0.001). Regarding ureteral stents, they cause similar morbidities (20.7% and 24.4%; P=0.881), and median length of stay (3 days; P=0.947). NT and DL were more frequent in patients with higher stone burden. CONCLUSIONS Tubeless PCNL encompasses lower morbidity and should be considered as an option for select patients, particularly with less stone burden and uncomplicated procedures. Regarding ureteral stents, SL is a safe option and does not require further procedures for removal.

Abstract
Although the UK is the largest lamb meat producer in Europe, there are limited data available on sheep flock performance and on how sheep farmers manage their flocks. The aims of this study were to gather evidence on the types of disease control practices implemented in sheep flocks, and to explore husbandry factors associated with flock productivity. A questionnaire focusing on farm characteristics, general husbandry and flock health management was carried out in 648 farms located in the UK over summer 2016. Abattoir sales data (lamb sales over 12 months) was compared with the number of breeding ewes on farm to estimate flock productivity (number of lambs sold for meat per 100 ewes per farm per year). Results of a multivariable linear regression model, conducted on 615 farms with complete data, indicated that farms vaccinating ewes against abortion and clostridial agents and administering a group 4/5 anthelmintic to ewes (as recommended by the Sustainable Control of Parasites in Sheep Initiative) during quarantining had a greater flock productivity than farms not implementing these actions (P<0.01 and 0.02, respectively). Flocks with maternal breed types had higher productivity indexes compared with flocks with either pure hill or terminal breeds (P<0.01). Farms weighing lambs during lactation had greater productivity than those not weighing (P<0.01). Importantly, these actions were associated with other disease control practices, for example, treating individual lame ewes with an antibiotic injection, weaning lambs between 13 and 15 weeks of age and carrying out faecal egg counts, suggesting that an increase in productivity may be associated with the combined effect of these factors. This study provides new evidence on the positive relationship between sheep flock performance and disease control measures and demonstrates that lamb sales data can be used as a baseline source of information on flock performance and for farm benchmarking. Further research is needed to explore additional drivers of flock performance.

Abstract
Objective
The study aimed to assess (1) whether the severity of a TBI affects performance on a measure of memory, and (2) whether FSIQ, VIQ, and PIQ moderate recovery following TBI, over time, after controlling for severity of injury.
Method
TBI patients (n = 60) were recruited from admissions to the Loma Linda University Children’s Hospital (LLUCH). Indicators of memory and learning were assessed with the CMS for all the children (ages 6 to 16), while overall cognitive abilities were assessed with the WASI-II. These data are a component of a larger neuropsychology assessment battery collected at 3 and 12 months post-injury.
Results
Simple Linear Regression was conducted in SPSS. Results indicated that severity of injury explained a significant amount of the variance in participant’s performance on overall memory at the initial evaluation (R2 = .154). As severity of injury increased by one-point, general memory declined by .392 points, 95%CI [.820, 3.233] (p < .001). Three moderation analyses using model one of the PROCESS macro for SPSS were conducted to assess whether FSIQ, VIQ, or PIQ moderated recovery from TBI over time. We controlled for the severity of injury. FSIQ, VIQ, and PIQ did not significantly moderate verbal, nonverbal, or general memory recovery of moderate-to-severe TBI over time (ps > .05).
Conclusions
Results of the study suggest that, after controlling for severity of injury, FSIQ, VIQ, and PIQ did not significantly moderate recovery following a TBI. Given that research suggests that higher premorbid IQ is associated with more favorable outcomes, further investigation is warranted.

Abstract
PURPOSE To perform a cumulative analysis of the current evidence on the surgical and functional outcomes of bipolar endoscopic enucleation of the prostate (b-EEP) versus bipolar transurethral resection of the prostate (b-TURP). METHODS A systematic review of the literature was performed on PubMed, Ovid®, and Scopus® according to Preferred Reporting Items for Systematic Review and Meta-analysis Statement (PRISMA Statement). The meta-analysis was conducted using the Review Manager 5.3 software. Parameters of interest were surgical and functional outcomes. Weighted mean difference, and odds ratio with 95% confidence interval were calculated for continuous and binary variables, respectively. Pooled estimates were calculated using the random-effect model. RESULTS Fourteen comparative studies were included. No statistically significant difference in terms of overall baseline characteristics was found. b-EEP had higher amount of resected tissue (p < 0.0001), shorter catheter time (p = 0.006), lower Hb drop (p = 0.03), and shorter length of stay (p < 0.0001). Equally, overall post-operative complications were lower (p = 0.01) as well as short (p = 0.04), and long-term complication rate (p = 0.04). There was higher re-intervention rate in the b-TURP group (p = 0.02) whereas b-EEP group had smaller residual prostate volume (p = 0.03), and lower post-operative PSA values (p < 0.00001). At long term, b-EEP presented lower IPSS (p = 0.04), higher Qmax (p = 0.002), and lower PVR (p < 0.00001). CONCLUSIONS b-EEP is an effective and safe surgical treatment for BPO. This procedure might offer several advantages over standard b-TURP, including the resection of a larger amount of tissue within the same operative time, shorter hospitalization, lower risk of complications, and lower re-intervention rate. This was submitted to PROSPERO registry: CRD42019126748.

Abstract
OBJECTIVE To test the prevalence and predictors of major acute cardiovascular events (MACE) after transurethral prostate surgery (TPS). MATERIAL AND METHODS The American College of Surgeons National Surgical Quality Improvement Program database (2011-2016) was queried for patients who underwent transurethral resection of the prostate, photoselective vaporization, or laser enucleation. MACE included: cerebrovascular events, cardiac arrest, myocardial infarction, deep venous thrombosis requiring therapy, and pulmonary embolism episodes occurred up to 30 days after discharge. Univariable and multivariable logistic regression models tested MACE predictors and effect of MACE on perioperative mortality. Within covariates significant at univariable analyses a stepwise selection, based on Akaike Information Criterion values, was performed to fit the most appropriate multivariable model. RESULTS Overall 44,939 patients were included in our analyses. Of these 365 (0.8%) had MACE within 30 days after surgery. The strongest MACE predictors were recent congestive heart failure (odds ratio [OR]: 2.1, 95% confidence interval [CI]: 1.2-3.7, P = .007), transfusions (OR: 2.5, 95% CI: 1.5-4.1, P <.001) and preoperative Systemic Inflammatory Response Syndrome or sepsis (OR: 2.6, 95% CI: 1.6-4.2, P <.001). Similarly, inpatient (OR: 2.0, 95% CI: 1.6-2.5, P <.001) and nonelective (OR: 1.5, 95% CI: 1.1-2.1, P = .012) patients experienced higher MACE rates. Perioperative mortality rates were statistical significantly higher in MACE patients (OR: 13.1, 95% CI: 8.2-21.0, P <.001). CONCLUSION Up to 1% of patients undergoing transurethral prostate surgery experience MACE. MACE are burdened by high mortality rates (up to 14% in MACE patients). Proper patient selection and postoperative monitoring are necessary to reduce MACE incidence and mortality rates.

Abstract
BACKGROUND Basophils, eosinophils and monocytes may be involved in BCG-induced immune responses and be associated with outcomes of bladder cancer patients receiving intravesical BCG. Our objective was to explore the association of baseline counts of basophils, eosinophils and monocytes with outcomes of patients with high-grade T1 bladder cancer receiving a standard course of intravesical BCG. METHODS We retrospectively reviewed medical records of patients with primary T1 HG/G3 bladder cancer. After re-TURBT, patients were treated with a 6-week course of intravesical BCG induction followed by intravesical BCG every week for 3 weeks given at 3, 6, 12, 18, 24, 30 and 36 months from initiation of therapy The analysis of potential risk factors for recurrence, muscle invasion and cancer-specific and overall survival was performed using univariable Cox regression models. Those factors that presented, at univariate analysis, an association with the event at a liberal p < 0.1, have been selected for the development of a multivariable model. RESULTS A total of 1045 patients with primary T1 HG/G3 were included. A total of 678 (64.9%) recurrences, 303 (29.0%) progressions and 150 (14.3%) deaths were observed during follow-up. Multivariate analysis showed that logarithmic transformation of basophils count was associated with a 30% increment in the hazard of recurrence per unit increase of logarithmic basophils count (HR 1.30; 95% confidence interval 1.09-1.54; p = 0.0026). Basophil count modeled by quartiles was also significantly associated with time to recurrence [second vs. lower quartile HR 1.42 (1.12-1.79); p = 0.003, third vs. lower quartile HR 1.26 (1.01-1.57); p = 0.041; upper vs. lower quartile HR 1.36 (1.1-1.68); p = 0.005]. The limitations of a retrospective study are applicable. CONCLUSION Baseline basophil count may predict recurrence in BCG-treated HG/G3 T1 bladder cancer patients. External validation is warranted.

Abstract
Clinical and pre-clinical evidences indicate an association between inflammation and depression since increased levels of pro-inflammatory cytokines are associated with depression-related symptoms. Atorvastatin is a cholesterol-lowering statin that possesses pleiotropic effects including neuroprotective and antidepressant actions. However, the putative neuroprotective effect of atorvastatin treatment in the acute inflammation mice model of depressive-like behaviour has not been investigated. In the present study, we aimed to investigate the effect of atorvastatin treatment on lipopolysaccharide (LPS) induced depressive-like behaviour in mice. Mice were treated with atorvastatin (1 or 10 mg/kg, v.o.) or fluoxetine (30 mg/kg, positive control, v.o.) for 7 days before LPS (0.5 mg/kg, i.p.) injection. Twenty four hours after LPS infusion, mice were submitted to the forced swim test, tail suspension test or open field test. After the behavioural tests, mice were sacrificed and the levels of tumour necrosis factor-α (TNF-α), brain-derived neurotrophic factor (BDNF), glutathione and malondialdehyde were measured. Atorvastatin (1 or 10 mg/kg/day) or fluoxetine treatment prevented LPS-induced increase in the immobility time in the forced swim and tail suspension tests with no alterations in the locomotor activity evaluated in the open field test. Atorvastatin (1 or 10 mg/kg/day) or fluoxetine treatment also prevented LPS-induced increase in TNF-α and reduction of BDNF levels in the hippocampus and prefrontal cortex. Treatment with atorvastatin (1 or 10 mg/kg/day) or fluoxetine prevented LPS-induced increase in lipid peroxidation and the reduction of glutathione levels in the hippocampus and prefrontal cortex. The present study suggests that atorvastatin treatment exerted neuroprotective effects against LPS-induced depressive-like behaviour which may be related to reduction of TNF-α release, oxidative stress and modulation of BDNF expression.

Abstract
BACKGROUND Since the end of the XIX century, teaching of surgery has remained practically unaltered until now. With the dawn of video-assisted laparoscopy, surgery has faced new technical and learning challenges. Due to technological advances, from Internet access to portable electronic devices, the use of online resources is part of the educational armamentarium. In this respect, videos have already proven to be effective and useful, however the best way to benefit from these tools is still not clearly defined. AIMS To assess the importance of video-based learning, using an electronic questionnaire applied to residents and specialists of different surgical fields. METHODS Importance of video-based learning was assessed in a sample of 141 subjects, using a questionnaire distributed by a GoogleDoc online form. RESULTS We found that 98.6% of the respondents have already used videos to prepare for surgery. When comparing video sources by formation status, residents were found to use Youtube significantly more often than specialists (p < 0.001). Additionally, residents placed more value on didactic illustrations and procedure narration than specialists (p < 0.001). On the other hand, specialists prized surgeon's technical skill and the presence of tips and tricks much more than residents (p < 0.001). CONCLUSION Video-based learning is currently a hallmark of surgical preparation among residents and specialists working in Portugal. Based on these findings we believe that the creation of quality and scientifically accurate videos, and subsequent compilation in available video-libraries appears to be the future landscape for video-based learning.

Abstract
INTRODUCTION Smoking is an important risk factor for the development, recurrence and progression of bladder cancer. Our aim was to analyze smoking habits after diagnosis in bladder cancer patients. Additionally, we evaluated patient knowledge about smoking as a risk factor and the urologist role in promoting abstinence. MATERIAL AND METHODS A cross-sectional, observational and descriptive study was performed in bladder cancer patients, diagnosed between January 2013 and September 2015 (n = 160) in Braga Hospital, in Portugal. RESULTS Smoking history was present in 71.9% of the sample, with 21.9% current smokers, (40.7% of abstinence after diagnosis). Smoking was acknowledged as a risk factor by 74.4% of the sample, with only 51.3% of ever smokers and 24.4% of non-smokers recognizing smoking as the leading risk factor (p = 0.008). The presence of other household smokers were significantly higher in patients who continued smoking (40%) than in ex-smokers after diagnosis (4.2%) (p = 0.005). The majority of smokers at diagnosis (83.1%) were advised to quit by their urologist, but only one smoker (1.7%) was offered any specific intervention to aid in cessation. DISCUSSION Smoking is not recognized as the leading risk factor for bladder cancer. This limited awareness, associated with the known difficulties in quitting smoking and the observed lack of smoking cessation interventions, may account for the high current smoking prevalence, albeit in line with other studies. CONCLUSION This study highlights the need for efficient smoking cessation programs directed to bladder cancer patients.

Abstract
Accumulating evidence indicates an interaction between inflammation and depression since increased levels of pro-inflammatory cytokines are associated with depression-related symptoms. Melatonin is a hormone synthesized and secreted by the pineal gland with antioxidant, anti-inflammatory and antidepressant-like effects. In this way, it would be interesting to evaluate the putative antidepressant-like effect of melatonin treatment in an acute inflammation mice model of depression. The present study aimed to investigate the effect of melatonin treatment on lipopolysaccharide (LPS) induced depressive-like behavior, neuroinflammation, oxidative stress and alteration on brain-derived neurotrophic fator (BDNF) levels. Mice were treated with melatonin (10 mg/kg, i.p.) 30 min before LPS (0.5 mg/kg, i.p.) injection. Twenty-four hours after LPS infusion, mice were submitted to the behavioral tests and, thereafter, biochemical determinations were performed. Melatonin treatment prevented LPS-induced depressive-like behavior in the forced swim and tail suspension tests with no alterations in locomotor activity evaluated in the open field test. Melatonin attenuated LPS-induced increase in tumor necrosis factor-α (TNF-α) and reduction of BDNF levels in the hippocampus. Treatment with melatonin also prevented LPS-induced increase in lipid peroxidation and the reduction of glutathione levels in the hippocampus. In conclusion, the present study suggests that melatonin treatment exerted neuroprotective effects against LPS-induced depressive-like behavior which may be related to reduction of TNF-α release, oxidative stress and modulation of BDNF expression.

Abstract
Correct classification of cystoscopy images depends on the interpreter's experience. Bladder cancer is a common lesion that can only be confirmed by biopsying the tissue, therefore, the automatic identification of tumors plays a significant role in early stage diagnosis and its accuracy. To our best knowledge, the use of white light cystoscopy images for bladder tumor diagnosis has not been reported so far. In this paper, a texture analysis based approach is proposed for bladder tumor diagnosis presuming that tumors change in tissue texture. As is well accepted by the scientific community, texture information is more present in the medium to high frequency range which can be selected by using a discrete wavelet transform (DWT). Tumor enhancement can be improved by using automatic segmentation, since a mixing with normal tissue is avoided under ideal conditions. The segmentation module proposed in this paper takes advantage of the wavelet decomposition tree to discard poor texture information in such a way that both steps of the proposed algorithm segmentation and classification share the same focus on texture. Multilayer perceptron and a support vector machine with a stratified ten-fold cross-validation procedure were used for classification purposes by using the hue-saturation-value (HSV), red-green-blue, and CIELab color spaces. Performances of 91% in sensitivity and 92.9% in specificity were obtained regarding HSV color by using both preprocessing and classification steps based on the DWT. The proposed method can achieve good performance on identifying bladder tumor frames. These promising results open the path towards a deeper study regarding the applicability of this algorithm in computer aided diagnosis.

Abstract
A drug-eluting biodegradable ureteral stent (BUS) has been developed as a new approach for the treatment of urothelial tumors of upper urinary tract cancer. In a previous work, this system has proven to be a good carrier for anticancer drugs as a potential effective and sustainable intravesical drug delivery system. BUS has revealed to reduce in 75% the viability of human urothelial cancer cells (T24) after 72 h of contact and demonstrated minimal cytotoxic effect on human umbilical vein endothelial cells (HUVECs) which were used as a control. In this work, we studied the permeability of the anticancer drugs, such as paclitaxel and doxorubicin, alone or released from the BUS developed. We used 3 different membranes to study the permeability: polyethersulfone (PES) membrane, HUVECs cell monolayer, and an ex vivo porcine ureter. The ureter thickness was measured (864.51 μm) and histological analysis was performed to confirm the integrity of urothelium. Permeability profiles were measured during 8 h for paclitaxel and doxorubicin. The drugs per se have shown to have a different profile and as expected, increasing the complexity of the membrane to be permeated, the permeability decreased, with the PES being more permeable and the ex vivo ureter tissue being less permeable. The molecular weight has also shown to influence the permeability of each drug and a higher percentage for doxorubicin (26%) and lower for paclitaxel (18%) was observed across the ex vivo ureter. The permeability (P), diffusion (D), and partition (Kd) coefficients of paclitaxel and doxorubicin through the permeable membranes were calculated. Finally, we showed that paclitaxel and doxorubicin drugs released from the BUS were able to remain in the ex vivo ureter and only a small amount of the drugs can across the different permeable membranes with a permeability of 3% for paclitaxel and 11% for doxorubicin. The estimated amount of paclitaxel that remains in the ex vivo ureter tissue is shown to be effective to affect the cancer cell and not affect the noncancer cells.

Abstract
The landscape of the surgical management of urologic malignancies has dramatically changed over the past 20 years. On one side, better diagnostic and prognostic tools allowed better patient selection and more reliable surgical planning. On the other hand, the implementation of minimally invasive techniques and technologies, such as robot-assisted laparoscopy surgery and image-guided surgery, allowed minimizing surgical morbidity. Ultimately, these advances have translated into a more tailored approach to the management of urologic cancer patients. Following the paradigm of "precision medicine", contemporary urologic surgery has entered a technology-driven era of "precision surgery", which entails a range of surgical procedures tailored to combine maximal treatment efficacy with minimal impact on patient function and health related quality of life. Aim of this non-systematic review is to provide a critical analysis of the most recent advances in the field of surgical uro-oncology, and to define the current and future role of "precision surgery" in the management of genitourinary cancers.

Abstract
Application of polymers cross-linked by gamma irradiation on cutaneous wounds has resulted in the improvement of healing. Chitosan (CH) and poloxamer 407 (P407)-based hydrogels confer different advantages in wound management. To combine the properties of both compounds, a gamma-irradiated mixture of 0.75/25% (w/w) CH and P407, respectively, was obtained (CH-P), and several physical, chemical, and biological analyses were performed. Notably, gamma radiation induced changes in the mixture's thermal behavior, viscosity, and swelling, and exhibited stability at neutral pH. The thermal reversibility provided by P407 and the bacteriostatic effect of CH were maintained. Mice full-thickness wounds treated with CH-P diminished the wound area during the first days. Consequently, with this treatment, increased levels of macrophages, α-SMA, and collagen deposition in wounds were observed, indicating a more mature scar tissue. In conclusion, the new hydrogel CH-P, at physiologic pH, combined the beneficial characteristics of both polymers and produced new properties for wound management.
