Bullying is still a widespread social problem that needs serious attention. To date, research on this topic has shown that understanding the phenomenon requires a psychosocial perspective. The primary goal of the study is to identify the factors that contribute to the victimization of students with learning disabilities. The hypothesis is that the victimization experiences of this group of students can be explained by some socio-relational dynamics. Using a mediation model, this study demonstrates that perceived social integration completely mediates the association between the presence of learning disabilities and victimization experiences. This implies that students with learning disabilities are primarily victimized when they are not socially integrated into their class group. The implications for diagnosis and treatment are discussed.

Currently, in clinical practice there are still no useful markers available that are able to diagnose renal cancer in the early stages in the context of population screening. This translates into very high costs for healthcare systems around the world. Analysing urine using an electronic nose (EN) provides volatile organic compounds that can be easily used in the diagnosis of urological diseases. Although no convincing results have been published, some previous studies suggest that dogs trained to sniff urine can recognize different types of tumours (bladder, lung, breast cancer) with different success rates. We therefore hypothesized that urinary volatilome profiling may be able to distinguish patients with renal cancer from healthy controls. A total of 252 individuals, 110 renal patients and 142 healthy controls, were enrolled in this pilot monocentric study. For each participant, we collected, stabilized (at 37 °C) and analysed urine samples using a commercially available electronic nose (Cyranose 320®). Principal component (PCA) analyses, discriminant analysis (CDA) and ROC curves were performed to provide a complete statistical analysis of the sensor responses. The best discriminating principal component groups were identified with univariable ANOVA analysis. The study correctly identified 79/110 patients and 127/142 healthy controls, respectively (specificity 89.4%, sensitivity 71.8%, positive predictive value 84.04%, negative predictive value 80.37%). In order to test the study efficacy, the Cross Validated Accuracy was calculated (CVA 81.7%, p < 0.001). At ROC analysis, the area under the curve was 0.85. The results suggest that urine volatilome profiling by e-Nose seems a promising, accurate and non-invasive diagnostic tool in discriminating patients from controls. The low costs and ease of execution make this test useful in clinical practice.

It is considered to be particularly interesting to enrich the scientific overview investigating the comorbidities of specific learning disorders (SLDs) in young adults. Therefore, this study aims to investigate the psychosocial and relational profiles associated with the presence of learning difficulties in a population of university students. The hypothesis is that young adults with SLDs have lower psychological and socio-relational functioning than their typical-development peers. We further hypothesized that the socio-relational difficulties of students with SLDs could be explained not only by referring to the presence of a learning disorder, but also by considering some variables that may follow the experience of students with SLDs. The results highlighted that students with SLDs, compared to their typical-development peers, have low self-efficacy, high academic anxiety scores, emotional problems, and issues with peers. We finally suggest considering these aspects as early as the diagnostic process to facilitate an effective treatment plan for learning disorders to prevent, in terms of developmental trajectory, the manifestation of these aspects in adulthood.

Background/Aims: In partial nephrectomy with hilar clamping every minute of ischemia can impair renal function, thus great importance is having the controlled hypotension as a part of zero ischemia technique. The aim of the study is to evaluate the effects of hypotensive anesthesia on renal function, in patients undergoing robotic assisted partial nephrectomy (RAPN) , during surgery and at 3 months follow up. Methods: This is a prospective study of 100 patients, ASA 1-2, who underwent zero ischemia RAPN under controlled hypotension (CH) from December 2011 through to May 2013. Serum creatinine, BUN, estimated glomerular filtration rates (eGFR), fractional excretion of sodium (FSE) and technetium Tc 99m mercaptoacetyltriglycine (99mTC-MAG-3), renal scintigraphy with effective renal plasma flow (ERPF) were evaluated. Results: Mean duration of CH was 50±4 minutes. Acute renal failure wasn't observed in any of the patients. A significant variation of eGFR during the procedure and 24 hours after surgery was observed. No significant variation of BUN and FSE was detected. Comparing preoperative ERPF of the operated kidney with ERPF 3 months after surgery, it decreased by 2%. Conclusion: In patients with normal preoperative renal function CH didn't show any detrimental impact on renal function during and after robotic assisted partial nephrectomy.

Abstract Background Use of a locoregional analgesia technique, such as the ultrasound-guided transversus abdominis plane block (TAPb), can improve postoperative pain management. We investigated the role of TAPb in robotic partial nephrectomy, a surgery burdened by severe postoperative pain. Methods In this prospective trial, patients with American Society of Anesthesiologists class I–III physical status undergoing robotic partial nephrectomy were randomly assigned to standard general anesthetic plus ultrasound-guided TAPb (TAP group) or sole standard general anesthetic (NO-TAP group). The primary end point was morphine consumption 24 hours after surgery. Secondary outcomes were postoperative nausea and vomiting in the first 24 hours, sensitivity, and acute and chronic pain, as measured by multiple indicators. Results A total of 96 patients were evaluated: 48 patients in the TAP group and 48 in the NO-TAP group. Median morphine consumption after 24 hours was higher in the NO-TAP group compared with the TAP group (14.1 ± 4.5 mg vs 10.6 ± 4.6, P < 0.008). The intensity of acute somatic pain and the presence of chronic pain at three and six months were higher in the NO-TAP group. Conclusions Our results show that TAPb can significantly reduce morphine consumption and somatic pain, but not visceral pain. TAPb reduced the incidence of chronic pain.

PurposeFunctional outcomes of robot-assisted (RA) radical cystectomy (RC) with intracorporeal orthotopic neobladder (i-ON) have been poorly investigated. The study aimed to report functional outcomes of a prospective randomized controlled trial (RCT) comparing open RC (ORC) and RARC with i-ON.MethodsInclusion criteria were cT2-4/N0/M0, or BCG-failure high-grade urothelial carcinoma, candidate to RC with curative intent. A covariate adaptive randomization process was used, based on the following variables: BMI, ASA score, haemoglobin levels, cT-stage, neoadjuvant chemotherapy, urinary diversion. Day-time continence was defined as “totally dryness”, nigh-time continence as pad wetness ≤ 50 cc. Continence recovery probabilities were compared between arms with Kaplan–Meier method and Cox regression analysis was performed to identify predictors of continence recovery. HRQoL outcomes analysis was assessed with a generalized linear mixed effect regression (GLMER) model.ResultsOut of 116 patients randomized, 88 received ON. Quantitative analysis of functional outcomes reported similar results in terms of day continence, while a better night continence status in ORC cohort was observed. However, 1-yr day- and night-time continence recovery probabilities were comparable. Night-time micturition frequency < 3 h was the only predictor of nigh-time continence recovery. At GLMER, 1-yr body image and sexual functioning were significantly better in RARC cohort, while urinary symptoms were comparable between arms.ConclusionDespite superiority of ORC at quantitative night-time pad use analysis, we showed comparable day- and night-time continence recovery probabilities. At 1-yr analysis of HRQoL outcomes, urinary symptoms were comparable between arms, while RARC patients reported lower body image and sexual functioning worsening.

To compare outcomes of sutureless (SL) vs. renorrhaphy (RR) off-clamp robotic partial nephrectomy (ocRPN), we retrospectively analyzed procedures performed at our center, from January 2017 to April 2021, for cT1-2N0M0 renal masses. All the patients with a minimum follow-up < 1 month were excluded from the analysis. The trifecta rate defined surgical quality. Any worsening from chronic kidney disease (CKD) I-II to ≧ IIIa (from IIIa to ≧ IIIb, and from IIIb to ≧ IV) was considered as significant stage migration (sCKDsm). A 1:1 propensity score-matched (PSM) analysis minimized baseline imbalances between SL and RR cohorts in terms of age, gender, ASA score, baseline estimated glomerular filtration rate (eGFR), tumor size, and RENAL score. Logistic regression analyses identified predictors of trifecta achievement. Kaplan–Meier (KM) analysis assessed the impact of RR on significant chronic kidney disease sCKDsm-free survival (SMFS), while Cox regression analyses identified its predictors. Overall, 531 patients were included, with a median tumor size of 3.5 cm (IQR: 2.7–5); 70 (13%) presented with a cT2 mass. An SL approach was pursued in 180 cases, but 10 needed conversion to RR. After PSM analysis, patients receiving SL showed a higher trifecta rate (94% vs. 84%; p = 0.007). SMFS probabilities were comparable at KM analysis (log-rank = 0.69). Age (OR: 0.97; 95%CI: 0.95–0.99; p = 0.01), a RENAL score ≧ 10 (OR: 0.29; 95%CI: 0.15–0.57; p < 0.001), and RR (OR: 0.34; 95%CI: 0.17–0.67; p = 0.002) were independent predictors of trifecta achievement. Age (OR: 1.04; 95%CI: 1.003–1.07; p = 0.03) and baseline eGFR (OR: 0.99; 95%CI: 0.97–0.99; p = 0.05) independently predicted sCKDsm. Compared to RR, our experience seems to show that the SL approach significantly increased the probabilities of achieving the trifecta in the observed group of cases.

During laparoscopic surgery, the role of PEEP to improve outcome is controversial. Mechanistically, PEEP benefits depend on the extent of alveolar recruitment, which prevents ventilator-induced lung injury by reducing lung dynamic strain. The hypotheses of this study were that pneumoperitoneum-induced aeration loss and PEEP-induced recruitment are inter-individually variable, and that the recruitment-to-inflation ratio (R/I) can identify patients who benefit from PEEP in terms of strain reduction. Sequential study. Operating room. Seventeen ASA I-III patients receiving robot-assisted prostatectomy during Trendelenburg pneumoperitoneum. Patients underwent end-expiratory lung volume (EELV) and respiratory/lung/chest wall mechanics (esophageal manometry and inspiratory/expiratory occlusions) assessment at PEEP = 0 cmH2O before and after pneumoperitoneum, at PEEP = 4 and 12 cmH2O during pneumoperitoneum. Pneumoperitoneum-induced derecruitment and PEEP-induced recruitment were assessed through a simplified method based on multiple pressure-volume curve. Dynamic and static strain changes were evaluated. R/I between 12 and 4 cmH2O was assessed from EELV. Inter-individual variability was rated with the ratio of standard deviation to mean (CoV). Pneumoperitoneum reduced EELV by (median [IqR]) 410 mL [80–770] (p < 0.001) and increased dynamic strain by 0.04 [0.01–0.07] (p < 0.001), with high inter-individual variability (CoV = 70% and 88%, respectively). Compared to PEEP = 4 cmH2O, PEEP = 12 cmH2O yielded variable amount of recruitment (139 mL [96–366] CoV = 101%), causing different extent of dynamic strain reduction (median decrease 0.02 [0.01–0.04], p = 0.002; CoV = 86%) and static strain increases (median increase 0.05 [0.04–0.07], p = 0.01, CoV = 33%). R/I (1.73 [0.58–3.35]) estimated the decrease in dynamic strain (p ≤0.001, r = −0.90) and the increase in static strain (p = 0.009, r = −0.73) induced by PEEP, while PEEP-induced changes in respiratory and lung mechanics did not. Trendelenburg pneumoperitoneum yields variable derecruitment: PEEP capability to revert these phenomena varies significantly among individuals. High R/I identifies patients in whom higher PEEP mostly reduces dynamic strain with limited static strain increases, potentially allowing individualized settings. •Optimal PEEP for laparoscopy is debated. Aeration loss and recruitment vary among patients, warranting personalized settings.•IIn this study, 17 patients undergoing robot-assisted prostatectomy during Trendelenburg pneumoperitoneum were studied.•Pneumoperitoneum variably reduced FRC. PEEP 12 cmH20 yielded variable recruitment, leading to diverse effects on lung strain.•EELV-derived R/I well reflected the effect of PEEP on lung strain, identifying patients benefiting the most from higher PEEP.

PurposeTo report long-term oncologic and functional outcomes of a large consecutive single center series of Robot-assisted radical cystectomy (RARC)- intracorporeal (IC) Urinary Diversion (UD), identifying their predicting factors.MethodsA single center Bladder cancer (BC) database was queried for “RARC” and “ICUD”, including patients treated between January 2012 and September 2020. Kaplan–Meier curves were assessed disease-free (DFS), cancer-specific (CSS) and overall survival (OS) probability. Univariable (UV) and multivariable (MV) analysis were adopted to identify predictors of DFS, CSS and OS. Kaplan–Meier method evaluated day- and night-time continence recovery probabilities; UV and MV analysis were adopted to identify predictors of Day-time continence.ResultsOverall, 251 patients were included. Among them, 192 patients underwent intracorporeal ileal orthotopic neobladder (ION) (76.5%). Five-year DFS, CSS and OS rates were 66.5%, 65.4% and 61.5%; pT stage ≥ 3 and pathologic nodal involvement were identified as negative independent predictors of DFS (HR 2.39, p = 0.001, HR 4.64, p ≤  0.001), CSS (HR 2.20, p = 0.01, HR 3.97, p < 0.001) and OS (HR 2.25, p = 0.005, HR 3.95, p < 0.001). In RARC-ION patients, Trifecta rate was 64.1%. One-year day- and night-time continence rates were 78.6% and 48.3%. Age (HR 0.98, p = 0.03), female gender (HR 0.57, p = 0.008) and complications Clavien grade ≥ 3 (HR 0.55, p = 0.03) were identified as independent predictors of day-time incontinence.ConclusionsLong-term oncologic outcomes and their predicting factors seem aligned to the largest historical open series and multi-institutional robotic series data. According to the identified predicting factors undermining a proper achievement of day-time continence, this represents an objective support, in order to properly advice specific sub-group of patients.
