Abstract
Just as the androgen receptor (AR), the estrogen receptor α (ERα) is expressed in the prostate and is thought to influence prostate cancer (PCa) biology. Yet, the incomplete understanding of ERα functions in PCa hinders our ability to fully comprehend its clinical relevance and restricts the repurposing of estrogen-targeted therapies for the treatment of this disease. Using two human PCa tissue microarray cohorts, we first demonstrated that nuclear ERα expression was heterogeneous among patients, being only detected in half of tumors. Positive nuclear ERα levels were correlated with disease recurrence, progression to metastatic PCa, and patient survival. Using in vitro and in vivo models of the normal prostate and PCa, bulk and single-cell RNA-Seq analyses revealed that estrogens partially mimic the androgen transcriptional response and induce specific biological pathways linked to proliferation and metabolism. Bioenergetic flux assays and metabolomics confirmed the regulation of cancer metabolism by estrogens, supporting proliferation. Using cancer cell lines and patient-derived organoids, selective estrogen receptor modulators, a pure anti-estrogen, and genetic approaches impaired cancer cell proliferation and growth in an ERα-dependent manner. Overall, our study revealed that, when expressed, ERα functionally reprograms PCa metabolism, is associated with disease progression, and could be targeted for therapeutic purposes.

Abstract
The androgen inactivating UGT2B28 pathway emerges as a predictor of progression in prostate cancer (PCa). However, the clinical significance of UGT2B28 tumoral expression and its contribution to PCa progression remain unclear. Using the Canadian Prostate Cancer Biomarker Network biobank (CPCBN; n = 1512), we analyzed UGT2B28 tumor expression in relation to clinical outcomes in men with localized PCa. UGT2B28 was overexpressed in tumors compared to paired normal adjacent prostatic tissue and was associated with inferior outcomes. Functional analyses indicated that UGT2B28 promoted cell proliferation, and its expression was regulated by the androgen receptor (AR)/ARv7. Mechanistically, UGT2B28 was shown to be a protein partner of the endocytic adaptor protein huntingtin-interacting protein 1 (HIP1), increasing its stability and priming AR/epidermal growth factor receptor (EGFR) pathways, leading to ERK1/2 activation triggering cell proliferation and epithelial-to-mesenchymal transition (EMT). HIP1 knockdown in UGT2B28 positive cells, and dual pharmacological targeting of AR and EGFR pathways, abolished cell proliferative advantages conferred by UGT2B28. In conclusion, UGT2B28 is a prognosticator of progression in localized PCa, regulates both AR and EGFR oncogenic signaling pathways via HIP1, and therefore can be therapeutically targeted by using combination of existing AR/EGFR inhibitors.

Abstract
SIGNIFICANCE Prostate cancer is the most common cancer among men. An accurate diagnosis of its severity at detection plays a major role in improving their survival. Recently, machine learning models using biomarkers identified from Raman micro-spectroscopy discriminated intraductal carcinoma of the prostate (IDC-P) from cancer tissue with a ≥85 % detection accuracy and differentiated high-grade prostatic intraepithelial neoplasia (HGPIN) from IDC-P with a ≥97.8 % accuracy. AIM To improve the classification performance of machine learning models identifying different types of prostate cancer tissue using a new dimensional reduction technique. APPROACH A radial basis function (RBF) kernel support vector machine (SVM) model was trained on Raman spectra of prostate tissue from a 272-patient cohort (Centre hospitalier de l'Université de Montréal, CHUM) and tested on two independent cohorts of 76 patients [University Health Network (UHN)] and 135 patients (Centre hospitalier universitaire de Québec-Université Laval, CHUQc-UL). Two types of engineered features were used. Individual intensity features, i.e., Raman signal intensity measured at particular wavelengths and novel Raman spectra fitted peak features consisting of peak heights and widths. RESULTS Combining engineered features improved classification performance for the three aforementioned classification tasks. The improvements for IDC-P/cancer classification for the UHN and CHUQc-UL testing sets in accuracy, sensitivity, specificity, and area under the curve (AUC) are (numbers in parenthesis are associated with the CHUQc-UL testing set): +4 % (+8 % ), +7 % (+9 % ), +2 % (6%), +9 (+9) with respect to the current best models. Discrimination between HGPIN and IDC-P was also improved in both testing cohorts: +2.2 % (+1.7 % ), +4.5 % (+3.6 % ), +0 % (+0 % ), +2.3 (+0). While no global improvements were obtained for the normal versus cancer classification task [+0 % (-2 % ), +0 % (-3 % ), +2 % (-2 % ), +4 (+3)], the AUC was improved in both testing sets. CONCLUSIONS Combining individual intensity features and novel Raman fitted peak features, improved the classification performance on two independent and multicenter testing sets in comparison to using only individual intensity features.

Abstract
BACKGROUND Prostate cancer (PC) is the most frequently diagnosed cancer in North American men. Pathologists are in critical need of accurate biomarkers to characterize PC, particularly to confirm the presence of intraductal carcinoma of the prostate (IDC-P), an aggressive histopathological variant for which therapeutic options are now available. Our aim was to identify IDC-P with Raman micro-spectroscopy (RμS) and machine learning technology following a protocol suitable for routine clinical histopathology laboratories. METHODS AND FINDINGS We used RμS to differentiate IDC-P from PC, as well as PC and IDC-P from benign tissue on formalin-fixed paraffin-embedded first-line radical prostatectomy specimens (embedded in tissue microarrays [TMAs]) from 483 patients treated in 3 Canadian institutions between 1993 and 2013. The main measures were the presence or absence of IDC-P and of PC, regardless of the clinical outcomes. The median age at radical prostatectomy was 62 years. Most of the specimens from the first cohort (Centre hospitalier de l'Université de Montréal) were of Gleason score 3 + 3 = 6 (51%) while most of the specimens from the 2 other cohorts (University Health Network and Centre hospitalier universitaire de Québec-Université Laval) were of Gleason score 3 + 4 = 7 (51% and 52%, respectively). Most of the 483 patients were pT2 stage (44%-69%), and pT3a (22%-49%) was more frequent than pT3b (9%-12%). To investigate the prostate tissue of each patient, 2 consecutive sections of each TMA block were cut. The first section was transferred onto a glass slide to perform immunohistochemistry with H&E counterstaining for cell identification. The second section was placed on an aluminum slide, dewaxed, and then used to acquire an average of 7 Raman spectra per specimen (between 4 and 24 Raman spectra, 4 acquisitions/TMA core). Raman spectra of each cell type were then analyzed to retrieve tissue-specific molecular information and to generate classification models using machine learning technology. Models were trained and cross-validated using data from 1 institution. Accuracy, sensitivity, and specificity were 87% ± 5%, 86% ± 6%, and 89% ± 8%, respectively, to differentiate PC from benign tissue, and 95% ± 2%, 96% ± 4%, and 94% ± 2%, respectively, to differentiate IDC-P from PC. The trained models were then tested on Raman spectra from 2 independent institutions, reaching accuracies, sensitivities, and specificities of 84% and 86%, 84% and 87%, and 81% and 82%, respectively, to diagnose PC, and of 85% and 91%, 85% and 88%, and 86% and 93%, respectively, for the identification of IDC-P. IDC-P could further be differentiated from high-grade prostatic intraepithelial neoplasia (HGPIN), a pre-malignant intraductal proliferation that can be mistaken as IDC-P, with accuracies, sensitivities, and specificities > 95% in both training and testing cohorts. As we used stringent criteria to diagnose IDC-P, the main limitation of our study is the exclusion of borderline, difficult-to-classify lesions from our datasets. CONCLUSIONS In this study, we developed classification models for the analysis of RμS data to differentiate IDC-P, PC, and benign tissue, including HGPIN. RμS could be a next-generation histopathological technique used to reinforce the identification of high-risk PC patients and lead to more precise diagnosis of IDC-P.

Abstract
BACKGROUND Perturbation of the major UGT2B17-dependent androgen catabolism pathway has the potential to affect prostate cancer (PCa) progression. The objective was to evaluate UGT2B17 protein expression in primary tumours in relation to hormone levels, disease characteristics and cancer evolution. METHODS We conducted an analysis of a high-density prostate tumour tissue microarray consisting of 239 localised PCa cases treated by radical prostatectomy (RP). Cox proportional hazard ratio analysis was used to evaluate biochemical recurrence (BCR), and a linear regression model evaluated variations in circulating hormone levels measured by mass spectrometry. The transcriptome of UGT2B17 in PCa was established by using RNA-sequencing data. RESULTS UGT2B17 expression in primary tumours was associated with node-positive disease at RP and linked to circulating levels of 3α-diol-17 glucuronide, a major circulating DHT metabolite produced by the UGT2B17 pathway. UGT2B17 was an independent prognostic factor linked to BCR after RP, and its overexpression was associated with development of metastasis. Finally, we demonstrated that distinctive alternative promoters dictate UGT2B17-dependent androgen catabolism in localised and metastatic PCa. CONCLUSIONS The androgen-inactivating gene UGT2B17 is controlled by overlooked regulatory regions in PCa. UGT2B17 expression in primary tumours influences the steroidome, and is associated with relevant clinical outcomes, such as BCR and metastasis.

Abstract
291 Background: Tumour FDG-uptake is of prognostic value in high-risk and metastatic prostate cancer (PCa). The aim of this study is to investigate the underlying glucose metabolism mechanisms of 18F-FDG-uptake on PET/CT imaging in PCa. Methods: Retrospective analysis was conducted for 94 patients diagnosed with a Gleason sum ≥8 at biopsy who underwent 18F-FDG-PET/CT imaging before radical prostatectomy. GLUT1, GLUT12 and HK2 expression were blindly scored after immunohistochemistry on radical prostatectomy specimens by 3 pathologists. 18F-FDG-uptake in primary lesion was measured by a blinded reader using maximum standardized uptake value (SUVmax). Correlations between GLUT1, GLUT12 and HK2 and SUVmax were assessed using Spearman’s rank correlation test. Survival probabilities were based on the Kaplan-Meier method. Results: With a median follow-up of 4.5 years, 56% (n=53) of patients had biochemical recurrence, 7% (n=7) progressed to castration-resistant PCa (CRPC) disease, 13% (n=12) developed metastasis and 6% (n=6) died. Correlation was found between GLUT1 expression and SUVmax level (r=0.2512, p=0.0182). In addition, SUVmax was significantly higher in tumours with high GLUT1 expression (n=17, 5.74±1.67) than tumours with low GLUT1 expression (n=71, 2.68±0.31, P=0.0037). Also, contrary to GLUT12 and HEX2 expression, a significant association was found between GLUT-1 expression levels and SUVmax index (p=0.004), lymph node status (p=0.046), volume of cancer (P=0.013), CRPC-free survival (p=0.02) and metastasis-free survival (p=0.04). Conclusions: GLUT1 expression in PCa tumours correlates with 18F-FDG-uptake and poor prognostic factors. These results suggest that this transporter is involved in the molecular mechanism of 18F-FDG-uptake in high-risk PCa and raise interest in targeting metabolic dependencies of PCa cells as a selective anticancer strategy.

Abstract
INTRODUCTION During liver transplantation, graft ischemia-reperfusion injury leads to a systemic inflammatory response producing postoperative organ dysfunctions. The aim of this observational and prospective study was to compare the impact of Solution de conservation des organes et tissus (SCOT) 15 and University of Wisconsin (UW) preservation solutions on early cytokine release, postreperfusion syndrome and postoperative organ dysfunctions. METHODS Thirty-seven liver transplantations were included: 21 in UW Group and 16 in SCOT 15 group. Five cytokines were measured in systemic blood after anesthetic induction, 30minutes after unclamping portal vein and on postoperative day 1. RESULTS Following unclamping portal vein, cytokines were released in systemic circulation. Systemic cytokine concentrations were higher in UW than in SCOT 15 group: Interleukin-10, Interleukine-6. In SCOT 15 group, significant reduction of postreperfusion syndrome incidence and acute kidney injury were observed. Alanine and aspartate aminotransferase peak concentrations were higher in SCOT 15 group than in UW group. However, from postoperative day 1 to day 10, aminotransferase returned to normal values and did not differ between groups. CONCLUSIONS Compared to UW, SCOT 15 decreases systemic cytokine release resulting from graft ischemia-reperfusion injury and reduces incidence of postreperfusion syndrome and postoperative renal failure.

Abstract
Regulatory T cells (Treg) may play an important role in operational (clinical) tolerance (OT), a stable graft function without immunosuppression in an otherwise immunocompetent host, that is spontaneously observed in some patients many years after transplantation. Several ongoing clinical trials are currently testing the effects of donor-specific or non-specific Treg infusion with the goal to induce this state of OT a few months after liver transplantation (LT). The preliminary results of two of these trials have been recently published, and raise a number of comments and issues: (1) These two papers demonstrate that a 100 to 1000-fold ex-vivo expansion of Treg is possible in humans after 2 weeks of culture. The optimal human Treg dose is however not clearly established, and might be higher than the dose that would be expected from translating murine data. (2) A lot of concerns are remaining regarding the Treg purity before expansion, the Treg stability during in vitro culture and the in vivo fate of infused cells. A strict monitoring of Treg should thus be done at each step. (3) Since Treg may play a detrimental role in some conditions, such as viral diseases and cancer, potential LT recipients with such diseases should probably be excluded from the initial trials of Treg infusion. (4) The follow-up of tolerant liver recipients should include repeated liver biopsies and detection of autoantibodies and humoral response, in addition to conventional liver graft assessment, in order to prevent the development of immune complications related to immunosuppression withdrawal. (5) The final issue raised by Treg therapy in LT is the choice of the immunosuppressive regimen used before tapering or withdrawal, appropriate to preserve OT establishment.

Abstract
PURPOSE The aim of the pilot study was to assess by ultrasound changes in dimensions of lung consolidation and reaeration after drainage of large pleural effusion in patients with acute respiratory distress syndrome (ARDS). METHODS Lung ultrasound and blood gas were performed before, 2 hours (H2) and 24 hours (H24) after drainage of pleural effusion. Lung ultrasound aeration score was calculated. Cephalocaudal dimension and diaphragmatic transversal area of lung consolidation were measured. RESULTS Ten patients were studied. Median volume of drained effusion was 675 ml at H2 and 895 at H24. Two hours after drainage, dimension of cephalocaudal consolidation and diaphragmatic transversal area decreased significantly. Lung reaeration after drainage occurred mainly in latero-inferior and postero-superior regions. PaO2/FiO2 increased significantly at H24. CONCLUSIONS Ultrasound is a useful method to assess lung consolidation after pleural effusion drainage. Drainage of pleural effusion may lead to a decrease of lung consolidation and improvement of lung reaeration.

Abstract
AIM We determined whether the Y-box binding protein-1 (YB-1) and its binding partner, the X-linked ribosomal protein S4 (RPS4X), are associated with clinical outcome in bladder cancer. MATERIALS & METHODS A population of 167 patients with muscle-invasive bladder tumor without evidence of metastasis at time of cystectomy was analyzed retrospectively. YB-1 and RPS4X expressions were evaluated immunohistochemically in tumors and analyzed for association with clinical variables and survival. RESULTS Kaplan-Meier and multivariate Cox regression analyses indicated that low expression of RPS4X was associated with a higher risk of death or disease recurrence. In contrast, YB-1 was not significantly associated with either recurrence-free or overall survival. CONCLUSION Low RPS4X expression is associated with poor disease-specific and recurrence-free survival in bladder cancer.

Abstract
Abstract
Androgen inactivation occurs mainly through the glucuronidation conjugative reaction mediated by uridine diphospho-glucuronosyltransferase enzymes, namely UGT2B28. This metabolic pathway controls systemic and local androgen bioavailability along with other biotransformation and transport pathways. In this study, we examined the relationship between UGT2B28 protein expression, circulating steroid levels and prostate cancer phenotype. To study distribution of the UGT2B28 protein in prostatic tissues, we used a specific antipeptide antibody displaying no cross-reactivity against highly identical UGT2B family members. Findings revealed that UGT2B28 cytoplasmic staining of secretory cells was distinctive of early stage tumorigenesis (i.e. prostatic intraepithelial neoplasia) and cancer cells with a variable nuclear staining, whereas normal prostate presented only nuclear enzyme expression. Using tissue microarray analysis, we analyzed 239 localized prostate cancer cases that underwent radical prostatectomy. Compared to patients with prostate tumors displaying absent or weak UGT2B28 staining, those with tumors presenting strong UGT2B28 nuclear expression had significantly lower PSA levels at diagnosis (20%; p = 0.043). UGT2B28 expression in the cytoplasm was also correlated with Gleason scores (p≤0.03) and nodal invasion status (p = 0.024). After adjustments for known prognostic markers including PSA, Gleason score, margin and nodal status, tumor size, smoking and germline UGT2B28 deletion status, overexpression of the UGT2B28 protein was an adverse and independent prognostic factor associated with disease recurrence and/or death (HR = 2.82; 95%CI, 1.09-7.36; p = 0.033). Remarkably, prostatic overexpression of UGT2B28 concurs with 30% higher circulating levels of testosterone (p = 0.004) and dihydrotestosterone (p = 0.002), measured by mass spectrometry. Our observations demonstrate that an increased expression of the UGT2B28 enzyme is associated with circulating steroid hormone levels, disease aggressiveness and risk of cancer progression.

Abstract
The aim of the present study was to determine the relationship between tracheotomy and ventilator-associated pneumonia (VAP). The study used a retrospective case-control study design based on prospective data. All nontrauma immunocompetent patients, intubated and ventilated for >7 days, were eligible for inclusion in the study. A diagnosis of VAP was based on clinical, radiographical and microbiological criteria. Four matching criteria were used, including duration of mechanical ventilation (MV). The indication and timing of tracheotomy were at the discretion of attending physicians. Univariate and multivariate analyses were performed to determine risk factors for VAP in cases (patients with tracheotomy) and controls (patients without tracheotomy). In total, 1,402 patients were eligible for inclusion. Surgical tracheotomy was performed in 226 (16%) patients and matching was successful for 177 (78%). The rate of VAP (22 versus 14 VAP episodes.1,000 MV-days(-1)) was significantly higher in controls than in cases. The rate of VAP after tracheotomy in cases, or after the corresponding day of MV in controls, was also significantly higher in control than in case patients (9.2 versus 4.8 VAP episodes.1,000 MV-days(-1)). In multivariate analysis, neurological failure (odds ratio (95% confidence interval) 2.7 (1.3-5)), antibiotic treatment (2.1 (1.1-3.2)) and tracheotomy (0.18 (0.1-0.3)) were associated with VAP. In summary, the present study demonstrates that tracheotomy is independently associated with decreased risk for ventilator-associated pneumonia.
