    My recent engagement as music director and conductor of Robert Nelson’s A Room with a View (1992, rev. 2004) has offered me the valuable opportunity to work on an opera side by side with its composer. The purpose of this dissertation is to reconstruct the various stages of the process of creation, interpretation, and performance of a contemporary opera, addressing aspects of the collaboration between the composer and the conductor. The methodology used in my research is based primarily on direct observation and interview. The investigation is conducted from the perspective of a “participant-observer,” due to my personal involvement in the project, as music director and conductor first, and then as interviewer and researcher. The document will be organized in three sections: - the first chapter will establish the context and specific features of my research, providing a scholarly background in relation to the study of the relationship between composer and conductor; - the second chapter will focus on the process of composition in all its stages. I have defined this as the “extended creative process” of A Room with a View; - the third chapter will discuss the Michigan State University production of the opera, considering several aspects of the artistic collaboration between Robert Nelson and me, as well as my involvement in the process as conductor. Through my research, I wish to provide useful insight into the crucial aspects of the composition and the production of new music. In addition, the project aims to offer a fresh contribution to the investigation of the relationship between composers and interpreters, and perhaps could provide some background reference for an interrogation about the current state and the future of American opera

    Purpose The primary aim of this study was to evaluate if exposure to 5-alpha-reductase inhibitors (5-ARIs) modifies the effect of MRI for the diagnosis of clinically significant Prostate Cancer (csPCa) (ISUP Gleason grade >= 2).Methods This study is a multicenter cohort study including patients undergoing prostate biopsy and MRI at 24 institutions between 2013 and 2022. Multivariable analysis predicting csPCa with an interaction term between 5-ARIs and PIRADS score was performed. Sensitivity, specificity, and negative (NPV) and positive (PPV) predictive values of MRI were compared in treated and untreated patients.Results 705 patients (9%) were treated with 5-ARIs [median age 69 years, Interquartile range (IQR): 65, 73; median PSA 6.3 ng/ml, IQR 4.0, 9.0; median prostate volume 53 ml, IQR 40, 72] and 6913 were 5-ARIs naive (age 66 years, IQR 60, 71; PSA 6.5 ng/ml, IQR 4.8, 9.0; prostate volume 50 ml, IQR 37, 65). MRI showed PIRADS 1-2, 3, 4, and 5 lesions in 141 (20%), 158 (22%), 258 (37%), and 148 (21%) patients treated with 5-ARIs, and 878 (13%), 1764 (25%), 2948 (43%), and 1323 (19%) of untreated patients (p < 0.0001). No difference was found in csPCa detection rates, but diagnosis of high-grade PCa (ISUP GG >= 3) was higher in treated patients (23% vs 19%, p = 0.013). We did not find any evidence of interaction between PIRADS score and 5-ARIs exposure in predicting csPCa. Sensitivity, specificity, PPV, and NPV of PIRADS >= 3 were 94%, 29%, 46%, and 88% in treated patients and 96%, 18%, 43%, and 88% in untreated patients, respectively.Conclusions Exposure to 5-ARIs does not affect the association of PIRADS score with csPCa. Higher rates of high-grade PCa were detected in treated patients, but most were clearly visible on MRI as PIRADS 4 and 5 lesions.Trial registration The present study was registered at ClinicalTrials.gov number: NCT05078359

    Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

    A signal based approach for condition monitoring and predictive maintenance of a capsule filler machine

    The need to increase manufacturing systems productivity and reduce their downtimes has led researchers to investigate and develop Predictive Maintenance practices. One of the major challenges to cope with Predictive Maintenance is related with the health assessment and analytics (i.e.: diagnostic and prognostic methods): the identification of the incoming faults is difficult and hard to deploy in complex automated machinery operating in real life conditions. At state of the art, established approaches are based on locating specific sensors as near as possible to the potential failure. However, such approach is expensive and often hard to realize due to machine topologies. The present work deals with a fault detection signal based approach, which analyses the vibrations of a complete pharmaceutical capsule filler machine and detects the signature of a fault on a critical stage to build a pattern threshold for Predictive Maintenance. The main novelty and strength of the proposed engineering method is that the detection can be achieved despite the sensor position and in presence of many sources, as it is in real life industrial environments. An industrial case study, on a pharmaceutical capsule filler is presente

    Bladder Metastases from Breast Cancer: Managing the Unexpected. A Systematic Review

    Breast cancer (BrC) has the highest incidence among females world over and it is one of the most common causes of death from cancer overall. Its high mortality is mostly due to its propensity to rapidly spread to other organs through lymphatic and blood vessels in spite of proper treatment. Bladder metastases from BrC are rare, with 50 cases having been reported in the last 60 years. This review aims to discuss some critical points regarding this uncommon condition. First, we performed a systematic review of the literature in order to draw a clinical and pathological profile of this entity. On this basis, its features in terms of diagnostic issues, imaging techniques, and survival are critically examined. Most bladder metastases from BrC are secondary lobular carcinoma, which mimic very closely the rare variant of urothelial cancer with lobular carcinoma-like features (uniform cells with an uncohesive single-cell, diffusely invasive growth pattern); thus, immunohistochemistry is mandatory to arrive at a correct diagnosis. This article summarizes the current knowledge regarding the incidence, clinical presentation, diagnosis, prognosis, and treatment of bladder metastases in patients with BrC

    No full text
    The aim of this study was to evaluate caregiver burden and quality of life (QoL) in active treatment settings and hospice care for 76 family caregivers of advanced cancer patients, using the Medical Outcomes Study Short Form and the Caregiver Burden Inventory. Compared to the active group, the hospice group reported significantly lower QoL scores in mental component summary score and higher scores in general health subscale and in physical component summary score. Future research needs to further investigate the complexities of caregivers’ needs, especially in the emotional and mental domains, and offer effective, clinically proven intervention

    Inhibition of Lon protease by triterpenoids alters mitochondria and is associated to cell death in human cancer cells

    Mitochondrial Lon protease (Lon) regulates several mitochondrial functions, and is inhibited by the anticancer molecule triterpenoid 2-cyano-3, 12-dioxooleana-1,9(11)-dien-28-oic acid (CDDO), or by its C-28 methyl ester derivative (CDDO-Me). To analyze the mechanism of action of triterpenoids, we investigated intramitochondrial reactive oxygen species (ROS), mitochondrial membrane potential, mitochondrial mass, mitochondrial dynamics and morphology, and Lon proteolytic activity in RKO human colon cancer cells, in HepG2 hepatocarcinoma cells and in MCF7 breast carcinoma cells. We found that CDDO and CDDO-Me are potent stressors for mitochondria in cancer cells, rather than normal non-transformed cells. In particular, they: i) cause depolarization; ii) increase mitochondrial ROS, iii) alter mitochondrial morphology and proteins involved in mitochondrial dynamics; iv) affect the levels of Lon and those of aconitase and human transcription factor A, which are targets of Lon activity; v) increase level of protein carbonyls in mitochondria; vi) lead to intrinsic apoptosis. The overexpression of Lon can rescue cells from cell death, providing an additional evidence on the role of Lon in conditions of excessive stress load

    Objective: To investigate survival outcomes in endometrioid endometrial cancer (EEC) patients with single vs. multiple positive pelvic lymph nodes. Methods: We performed a retrospective evaluation of all consecutive patients with histologically proven International Federation of Gynecology and Obstetrics (FIGO) stage IIIC1 EEC who underwent primary surgical treatment between 2004 and 2014 at seven Italian gynecologic oncology referral centers. Patients with pre-or intra-operative evidence of extrauterine disease (including the presence of bulky nodes) and patients with stage IIIC2 disease were excluded, in order to obtain a homogeneous population. Results: Overall 140 patients met the inclusion criteria. The presence of >1 metastatic pelvic node was significantly associated with an increased risk of recurrence and mortality, compared to only 1 metastatic node, at both univariate (recurrence: hazard ratio [HR]=2.19; 95% confidence interval [CI]=1.2–3.99; p=0.01; mortality: HR=2.8; 95% CI=1.24–6.29; p=0.01) and multivariable analysis (recurrence: HR=1.91; 95% CI=1.02–3.56; p=0.04; mortality: HR=2.62; 95% CI=1.13–6.05; p=0.02) and it was the only independent predictor of prognosis in this subset of patients. Disease-free survival (DFS) and disease-specific survival (DSS) were significantly longer in patients with only 1 metastatic node compared to those with more than 1 metastatic node (p=0.008 and 0.009, respectively). Conclusion: The presence of multiple metastatic nodes in stage IIIC1 EEC represents an independent predictor of worse survival, compared to only one positive node. Our data suggest that EEC patients may be categorized according to the number of positive nodes
