    Magnetic resonance imaging (MRI) targeted biopsy (TBx) of the prostate demonstrated to improve detection rate (DR) of clinically significant prostate cancer (csPCa) in biopsy-naive patients achieving strong level of evidence. Nevertheless, the csPCa yield for TBx alone versus TBx plus systematic biopsy (SBx) after accounting for overlapping of SBx cores with TBx cores, in prior-negative or active surveillance (AS) patients has not been well established.The objective of the study was to investigate benefits in terms of detection rate and pathological stratification of prostate cancer (PCa) using contextual SBx during MRI-TBx.Patients previously submitted to negative-SBx (cohort A) and those enrolled in an AS program (cohort B) who showed at least 1 suspicious area with a PIRADSv2 score ≥ 3 were prospectively and randomly assigned to only TBx strategy versus TBx plus SBx strategy. SBx locations could not encompass the TBx sites, so that the results of each type of biopsy were independent and did not overlap.A total of 312 patients were included in the 2 cohorts (cohort A: 213 cases; cohort B: 99 cases). No significant differences were found in terms of overall PCa-DR (77.6% vs 69.6% respectively; P = .36) and csPCa-DR (48.2% vs 60.9 respectively; P = .12). The MRI-TBx alone cohort showed higher csPCa/PCa ratio (87.5% vs 62.2%; P = .03). The MRI-TBx plus SBx group subanalysis showed significantly higher csPCa-DR obtained at the MRI-TBx cores when compared with the SBx cores (43.7% vs 24.1%, respectively; P = .01). Independently to age, prostatic-specific antigen and prostate imaging-reporting and data system score, either in rebiopsy (OR 0.43, 0.21-0.97) or AS (OR 0.46, 0.32-0.89) setting, SBx cores were negatively associated with the csPCa-DR when combined to TBx cores.MRI-TBx should be considered the elective method to perform prostate biopsy in patients with previous negative SBx and those considered for an AS program. Adding SBx samples to MRI-TBx did not improve detection rate of csPCa

    Background Depressive symptoms are associated with adverse clinical outcomes in patients with end-stage kidney disease; however, few small studies have examined this association in patients with earlier phases of chronic kidney disease (CKD). We studied associations between baseline depressive symptoms and clinical outcomes in older patients with advanced CKD and examined whether these associations differed depending on sex. Methods CKD patients (>= 65 years; estimated glomerular filtration rate <= 20 mL/min/1.73 m(2)) were included from a European multicentre prospective cohort between 2012 and 2019. Depressive symptoms were measured by the five-item Mental Health Inventory (cut-off <= 70; 0-100 scale). Cox proportional hazard analysis was used to study associations between depressive symptoms and time to dialysis initiation, all-cause mortality and these outcomes combined. A joint model was used to study the association between depressive symptoms and kidney function over time. Analyses were adjusted for potential baseline confounders. Results Overall kidney function decline in 1326 patients was -0.12 mL/min/1.73 m(2)/month. A total of 515 patients showed depressive symptoms. No significant association was found between depressive symptoms and kidney function over time (P = 0.08). Unlike women, men with depressive symptoms had an increased mortality rate compared with those without symptoms [adjusted hazard ratio 1.41 (95% confidence interval 1.03-1.93)]. Depressive symptoms were not significantly associated with a higher hazard of dialysis initiation, or with the combined outcome (i.e. dialysis initiation and all-cause mortality). Conclusions There was no significant association between depressive symptoms at baseline and decline in kidney function over time in older patients with advanced CKD. Depressive symptoms at baseline were associated with a higher mortality rate in men

    Evolving trends in the management of acute appendicitis during COVID-19 waves. The ACIE appy II study

    Get PDF
    Background: In 2020, ACIE Appy study showed that COVID-19 pandemic heavily affected the management of patients with acute appendicitis (AA) worldwide, with an increased rate of non-operative management (NOM) strategies and a trend toward open surgery due to concern of virus transmission by laparoscopy and controversial recommendations on this issue. The aim of this study was to survey again the same group of surgeons to assess if any difference in management attitudes of AA had occurred in the later stages of the outbreak. Methods: From August 15 to September 30, 2021, an online questionnaire was sent to all 709 participants of the ACIE Appy study. The questionnaire included questions on personal protective equipment (PPE), local policies and screening for SARS-CoV-2 infection, NOM, surgical approach and disease presentations in 2021. The results were compared with the results from the previous study. Results: A total of 476 answers were collected (response rate 67.1%). Screening policies were significatively improved with most patients screened regardless of symptoms (89.5% vs. 37.4%) with PCR and antigenic test as the preferred test (74.1% vs. 26.3%). More patients tested positive before surgery and commercial systems were the preferred ones to filter smoke plumes during laparoscopy. Laparoscopic appendicectomy was the first option in the treatment of AA, with a declined use of NOM. Conclusion: Management of AA has improved in the last waves of pandemic. Increased evidence regarding SARS-COV-2 infection along with a timely healthcare systems response has been translated into tailored attitudes and a better care for patients with AA worldwide

    Il seguente lavoro riguarda il processo di calibrazione di un modello di simulazione dinamica di una palazzina uffici attraverso il software TRNSYS. Per procedere alla calibrazione ho dovuto monitorare i consumi energetici effettivi dell'edificio e per farlo ho utilizzato un contacalorie, montato direttamente in centrale termica dell'edificio, che ha registrato i dati di interesse per un periodo di tempo di 54 giorni. Per considerare la calibrazione di buona qualità si utilizzano gli indici statistici CV(RMSE) e MBE che devono rispettare i valori soglia consigliati dall'ASHRAE. Una volta terminata la calibrazione ho analizzato i livelli di comfort, sia termico che acustico, e le prestazioni energetiche della palazzina che si hanno a seguito di una riqualificazione energetica. La riqualificazione riguarda sia il miglioramento delle proprietà termofisiche dell'involucro, prevedendo la coibentazione dei componenti opachi e la sostituzione dei componenti finestrati, sia il cambio del sistema di generazione di calore, passando dalla caldaia, alla pompa di calore fino ad arrivare alla logica ibrida caldaia più pompa di calore. Gli interventi di riqualificazione sono stati valutati anche dal punto di vista economico calcolando il Pay-Back time dell'investimento. I risultati che ottengo mi portano a dire che gli interventi di riqualificazione dell'involucro non sono convenienti dal punto di vista economico, in quanto molto costosi e fatti su una palazzina che ha dei consumi energetici non troppo alti, però mi permettono di ottenere un miglioramento del comfort sia termico che acustico. L'utilizzo della pompa di calore mi porta agli stessi risultati che ottengo con la caldaia, ma con questo sistema di generazione ho dei problemi a gestire i picchi di potenza che ho all'accensione dell'impianto. Tale svantaggio può essere superato se si utilizza la logica ibrida pompa di calore più caldaia

    In this paper, the architecture of an innovative tool, enabling researchers to create in an automatic way suitable datasets for Artificial Intelligence (AI) applications in the Earth Observation (EO) context, is presented. Two versions of the architecture have been implemented and made available on Git-Hub, with a specific Graphical User Interface (GUI) suitable for non-expert users. The tool has been designed to work with different types of sensors, but up to now has been tested with Sentinel-2 and Sentinel-1 data. We strongly believe that this tool will be of great usefulness for researchers applying AI to EO and Remote Sensing (RS). At the best of our knowledge, there is not a similar freely available tool, collecting the same benefits

    Introduction: Modern medicine uses increasingly innovative techniques that require more and more capabilities for acquisition. In the urological department is increasing the presence of patients with lower urinary tract symptoms (LUTS) and transurethral resection of the prostate (TURP) is the standard of care in their surgical treatment. We report our surgical experience and learning curve of using bipolar plasmakinetic devices in the training of urological residents to benign prostatic hyperplasia (BPH) treatment. Materials and Methods: 80 patients with benign prostatic enlargement due to BPH were enrolled in the study. TURP has been performed by three urological residents and by an expe- rienced urologist. Patients were evaluated before and 6 months after the endoscopic bipolar plasmakinetic resection using the International Prostate Symptom Score (IPSS), maximum uri- nary flow rate (Qmax), postvoid residual urine (PVR) and prostate specific antigen (PSA). Results: Overall 60 procedures were performed, 18 PlasmaKinetic (PK)-TURP procedures were completed by the three residents. In the other 42 cases the procedures were completed by the experienced urologist. In eight cases there was a capsular perforation and the experienced urol- ogist replaced the resident to complete the resection. No complications have been reported in the procedures completed by the senior urologist. All complications caused by the residents were man- aged intraoperatively without changing the course of the procedure. Statistical differences were observed regarding IPSS, quality of life (QoL), and PVR at 6-month follow-up when procedures completed by urological residents were compared to those completed by the senior urologist. Conclusion: Bipolar device represents appropriate tools to acquire endoscopic skills. It is safe and it can be used at the first experience of BPH treatment by a resident who has not previ- ously approached this endoscopic surgical procedure
