Abstract
This review systematically addresses the correlation between the microbiome and prostate cancer and explores its diagnostic and therapeutic implications. Recent research has indicated an association between the urinary and gut microbiome composition and prostate cancer incidence and progression. Specifically, the urinary microbiome is a potential non-invasive biomarker for early detection and risk evaluation, with altered microbial profiles in prostate cancer patients. This represents an advancement in non-invasive diagnostic approaches to prostate cancer. The role of the gut microbiome in the efficacy of various cancer therapies has recently gained attention. Gut microbiota variations can affect the metabolism and effectiveness of standard treatment modalities, including chemotherapy, immunotherapy, and hormone therapy. This review explores the potential of gut microbiome modification through dietary interventions, prebiotics, probiotics, and fecal microbiota transplantation for improving the treatment response and mitigating adverse effects. Moreover, this review discusses the potential of microbiome profiling for patient stratification and personalized treatment strategies. While the current research identifies the pivotal role of the microbiome in prostate cancer, it also highlights the necessity for further investigations to fully understand these complex interactions and their practical applications in improving patient outcomes in prostate cancer management.

Abstract
We investigated the prognosis of BCG induction-only treatment and non-complete response (CR) at the first 3-month evaluation and examined factors associated with CR. In total, 209 patients with moderate- and high-risk NMIBC who received BCG induction-only treatment between 2008 and 2020 were retrospectively analyzed. Recurrence-free survival (RFS) and progression-free survival (PFS) were assessed based on the initial NMIBC stage. PFS and associated factors of non-CR compared to CR were also assessed. Initial T1 high-grade (HG) (n = 93) had poorer RFS and PFS after BCG induction-only treatment than Ta low-grade (LG) (p = 0.029, p = 0.002). Non-CR (n = 37) had a different neutrophil-to-lymphocyte ratio (NLR) (2.81 ± 1.02 vs. 1.97 ± 0.92) and T staging from CR (p < 0.001, p = 0.008). T1HG recurrence was associated with a worse PFS compared to non-T1HG (13.7 months vs. 101.7 months, p < 0.001). There was no difference in PFS between T1HG and T1LG. T1 and NLR were predictors of response at 3 months in multivariable analysis (p = 0.004, p = 0.029). NLR was also found to be an associated factor with RFS and PFS of bladder cancer (p < 0.001, p < 0.001). BCG induction-only treatment was effective for high-risk TaLG but not for T1HG. T1HG recurrence at 3 months after BCG induction has a poor prognosis for bladder cancer. Preoperative NLR and T1 were predictors of non-CR, and NLR was also associated with the long-term prognosis of bladder cancer.

Abstract
HostSeq was launched in April 2020 as a national initiative to integrate whole genome sequencing data from 10,000 Canadians infected with SARS-CoV-2 with clinical information related to their disease experience. The mandate of HostSeq is to support the Canadian and international research communities in their efforts to understand the risk factors for disease and associated health outcomes and support the development of interventions such as vaccines and therapeutics. HostSeq is a collaboration among 13 independent epidemiological studies of SARS-CoV-2 across five provinces in Canada. Aggregated data collected by HostSeq are made available to the public through two data portals: a phenotype portal showing summaries of major variables and their distributions, and a variant search portal enabling queries in a genomic region. Individual-level data is available to the global research community for health research through a Data Access Agreement and Data Access Compliance Office approval. Here we provide an overview of the collective project design along with summary level information for HostSeq. We highlight several statistical considerations for researchers using the HostSeq platform regarding data aggregation, sampling mechanism, covariate adjustment, and X chromosome analysis. In addition to serving as a rich data source, the diversity of study designs, sample sizes, and research objectives among the participating studies provides unique opportunities for the research community.

Abstract
INTRODUCTION We assessed the effects of exercise on the physical function and health quality of life (hQoL) in prostate cancer patients underwent androgen deprivation therapy (ADT). Additionally, the effects of high-intensity interval training (HIIT) on the physical function and hQoL in these patients were compared with those of moderate-intensity continuous training (MICT). METHODS Seventeen prostate cancer patients who underwent ADT were prospectively allocated to either HIIT (n = 9) or MICT (n = 8). In these patients, physical function and hQoL were measured before and after 12 weeks of exercise and 3-6 months after the exercise program, respectively. RESULTS Although the whole-body total mass significantly increased after the exercise program, it was equivalent regardless of the exercise methods. After the exercise program, muscle strength and endurance improved and tended to be maintained until 3-6 months later. Improvement in muscle endurance was more prominent after HIIT, and that in muscle strength was more prominent after MICT. Performance in the senior fitness test improved after the exercise program, and HIIT was more effective for lower and upper muscle endurance and flexibility, although MICT was more effective for the others. The hQoL significantly improved 3-6 months after the exercise program. CONCLUSION The 12-week exercise program has a positive effect on the physical function and hQoL in prostate cancer patients who underwent ADT. In these patients, compared with MICT, HIIT may be a better option for improving muscle endurance, which is thought to be significant for preventing falls and fractures in elderly patients.

Abstract
PURPOSE This study aimed to investigate the practicality of percent body fat (PBF), calculated using bioelectrical impedance analysis (BIA), in predicting benign prostatic hyperplasia/lower urinary tract symptoms (BPH/LUTS). METHODS This study included 844 men who underwent medical checkups at our institution between 2014 and 2022. Demographic characteristics, serum PSA levels, and prostate volume were collected using TRUS. BPH was defined as a prostate volume ≥ 30 cc. Subjects were divided into two groups according to their quartiles of PBF: the normal PBF group (first to third quartile; PBF < 27.9%) and the high PBF group (fourth quartile; PBF ≥ 27.9%). Characteristics between the groups were compared using the chi-square test and Student's t-test. Multivariate logistic regression analysis was performed to evaluate risk factors for BPH and severe LUTS. RESULTS The prostate volume (25.21 ± 8.4 vs 27.30 ± 9.0, p = 0.005) and percentage of BPH (22.9% vs. 32.1%, p = 0.007) were greater in the high PBF group. After multivariate analysis, old age (OR = 1.066, p < 0.001), higher appendicular skeletal muscle mass index (ASMI) (OR = 1.544, p = 0.001), and PBF ≥ 27.9% (OR = 1.455, p = 0.037) were risk factors for BPH. Larger prostate volume (OR = 1.035, p = 0.002) and PBF ≥ 27.9% (OR = 1.715, p = 0.025) were risk factors for severe LUTS. However, a greater ASMI had a protective effect against severe LUTS (OR = 0.654, p = 0.011). CONCLUSIONS This study shows that PBF and ASMI are useful for predicting BPH/LUTS. We suggest that lowering PBF to the normal range in a population with high PBF might prevent BPH, while lowering PBF and maintaining adequate ASMI could lower LUTS.

Abstract
PURPOSE We assessed the effects of preoperative bladder compliance on the long-term functional outcomes, especially focused on postoperative storage symptom changes, after laser prostatectomy. MATERIALS AND METHODS From January 2008 to March 2014, 1,608 men who underwent laser prostatectomy, including holmium laser enucleation or photo-vaporization of the prostate, were included in the analysis. We divided patients into 3 groups according to bladder compliance on a baseline urodynamic study: <12.5, 12.5-25, ≥25 mL/cmH2O. A multivariable analysis was performed to determine the impact of bladder compliance on changes in long-term functional outcomes after laser prostatectomy. RESULTS Bladder compliance was less than 12.5 mL/cmH2O in 50 (3.1%), 12.5-25 mL/cmH2O in 232 (14.4%) patients. As bladder compliance decreased, the baseline International Prostate Symptom (IPSS) total score and storage sub-score were increased; the voiding sub-score remain unchanged. At postoperative 12 and 36 months, absolute improvements in the IPSS total score and storage sub-score were higher in <12.5 mL/cmH2O group compared to other groups, although those were equivalent at postoperative 1 months. On the multivariable analysis, decreased bladder compliance <12.5 mL/cmH2O was significantly associated with superior improvement in storage sub-score at postoperative 36 months, although it was not associated with voiding sub-score. CONCLUSIONS In patients with preoperative bladder compliance <12.5 mL/cmH2O, storage symptoms could be further improved at 36 months after laser prostatectomy compared to others. Thus, laser prostatectomy could be a considerable treatment option for patients with severely decreased bladder compliance.

Abstract
Purpose We investigated the effects of economic status (classified based on insurance type and residential area) on oncological outcomes of prostate cancer using a nationwide database. We additionally investigated oncological outcomes based on economic status and residential area in patients who underwent surgical treatment. Materials and Methods The study included 75,518 men with newly diagnosed prostate cancer between 2009 and 2018 in whom oncological outcomes were investigated based on economic status and residential area. Among the 75,518 men with prostate cancer, the data of 29,973 men who underwent radical prostatectomy were further analyzed. Multivariate analysis was performed to determine the effects of economic status and residential area on postoperative oncological outcomes. Results Among the 75,518 patients with prostate cancer, 3,254 (4.31%) were medical aid beneficiaries. The 5-year overall survival rates were 81.2% and 64.8% in the health insurance and medical aid groups, respectively. Radical prostatectomy was more common in the health insurance group, and surgical intervention was significantly affected by the residential area. Among patients who underwent surgery, 5-year androgen deprivation therapy-free and overall survival were better in the health insurance group. Multivariate analysis showed that insurance type and residential area were significantly associated with the androgen deprivation therapy-free and overall survival after adjustment for other variables. Conclusion Economic status and residential area were shown to affect not only treatment patterns but also post-diagnosis and postoperative oncological outcomes. Political support for early diagnosis and appropriate treatment of prostate cancer is warranted for medically vulnerable populations.

Abstract
OBJECTIVE Despite efforts to improve screening and early detection of prostate cancer (PC), no available biomarker has shown acceptable performance in patients with prostate-specific antigen (PSA) gray zones. We aimed to develop a deep learning-based prediction model with minimized parameters and missing value handling algorithms for PC and clinically significant PC (CSPC). MATERIALS AND METHODS We retrospectively analyzed data from 18 824 prostate biopsies collected between March 2003 and December 2020 from 2 databases, resulting in 12 739 cases in the PSA gray zone of 2.0-10.0 ng/mL. Dense neural network (DNN) and extreme gradient boosting (XGBoost) models for PC and CSPC were developed with 5-fold cross-validation. The area under the curve of the receiver operating characteristic (AUROC) was compared with that of serum PSA, PSA density, free PSA (fPSA) portion, and prostate health index (PHI). RESULTS The AUROC values in the DNN model with the imputation of missing values were 0.739 and 0.708 (PC) and 0.769 and 0.742 (CSPC) in internal and external validation, whereas those of the non-imputed dataset were 0.740 and 0.771 (PC) and 0.807 and 0.771 (CSPC), respectively. The performance of the DNN model was like that of the XGBoost model, but better than all tested clinical biomarkers for both PC and CSPC. The developed DNN model outperformed PHI, serum PSA, and percent-fPSA with or without missing value imputation. DISCUSSION DNN models for missing value imputation can be used to predict PC and CSPC. Further validation in real-life scenarios are need to recommend for actual implementation, but the results from our study support the increasing role of deep learning analytics in the clinical setting. CONCLUSIONS A deep learning model for PC and CSPC in PSA gray zones using minimal, routinely used clinical parameter variables and data imputation of missing values was successfully developed and validated.

Abstract
X-ray reflectivity was used to study the several-nanometer-thick "crowded" layers that form at the interfaces between a planar electrode and concentrated solutions of ionic liquids. The ionic liquid [P14,6,6,6]+[NTf2]- was dissolved in either strongly polar propylene carbonate or weakly polar dimethyl carbonate. In the range of 19-100 vol % ionic liquid, between working electrode potentials +2 and +2.75 V, uniform 2-7 nm thick interfacial layers were observed. These layers are not pure anions but contain three to five times as many anions as cations and about the same percentage of solvent as the bulk solution. On the other side of the layer, the density is that of the bulk solution. These features are inconsistent with a picture of the crowded layer as a region of pure, close-packed counterions. Not only the layer thickness but also the charge density decrease with increasing dilution at any given applied voltage. This appears to indicate, counterintuitively, that a thinner layer with lower net charge density will screen an electric field as effectively as a thicker layer with higher charge density.

Abstract
To compare the postoperative estimated-glomerular-filtration-rate (eGFR) and parenchymal changes between cold ischemia and zero/selective ischemia for a T1a mass. We analyzed 104 patients who underwent open partial nephrectomy with cold ischemia (53) or zero/selective ischemia (51) for T1a between 2008 and 2018 to determine postoperative renal function changes and associated factors. Postoperative renal function was expressed as (postoperative-eGFR - preoperative-eGFR)/preoperative-eGFR × 100%. Parenchymal enhancement and thicknesses of the ipsilateral kidney as tissue changes were measured on postoperative CT to identify the correlation with the renal function change. Patients with 10% or 25% decrease in eGFR were significantly more in the cold ischemia group (p = 0.032, p = 0.006). On multivariable analysis, preoperative eGFR, ischemic type, and percent change of parenchymal thickness were identified to be significantly associated with postoperative 12 months renal function (B = - 0.367, p = 0.020; B = 6.788, p = 0.042; B = 0.797, p = 0.029). Change in parenchymal thickness was negatively correlated with changes in postoperative renal function (r = - 0.277, p = 0.012). Changes in eGFR were associated with a decrease in parenchymal thickness and the type of ischemic technique. Zero/selective ischemia during partial nephrectomy may have an advantage in preserving postoperative renal function compared to cold ischemia.

Abstract
We evaluated the surgical margin status after radical prostatectomy according to sites positive for prostate cancer on standard 12-core transrectal ultrasound-guided prostate biopsy. Among patients who underwent radical prostatectomy at Boramae Medical Center, 520 patients with preoperative prostate-specific antigen (PSA) level < 20 ng/mL and locally confined prostate cancer on preoperative magnetic resonance imaging, treated with nerve-sparing radical prostatectomy, were included in the analysis. The surgical margin was positive for cancer in 166 (31.9% of the total) patients. The preoperative PSA level (9.3 vs. 8.0, ng/mL p = 0.001) and number of positive cores on 12-core prostate biopsy (4.1 vs. 3.4, p = 0.003) were significantly higher in patients with positive surgical margins. Moreover, the biopsy Gleason grade was higher in patients with positive surgical margins (p = 0.001). However, the pathologic Gleason grade and tumor volume were equivalent between the 2 groups. On multivariate analysis, the detection of prostate cancer on anterior lateral biopsy was associated with an increased rate of positive surgical margins (hazard ratio [HR]: 1.781, p = 0.008) after adjusting for other variables. Anterior lateral (HR: 1.919, p = 0.020), basal lateral (HR: 9.176, p < 0.001), basal medial (HR: 3.302, p = 0.031), and mid lateral (HR: 2.501, p = 0.044) biopsies were associated with positive apical, posterior, basal, and lateral surgical margins, respectively, after adjusting for other variables. The sites of prostate cancer on standard 12-core prostate biopsy could be useful for predicting surgical margin positivity after radical prostatectomy. In other words, clinicians should consider the sites of prostate cancer on prostate biopsy to reduce margin positivity after radical prostatectomy.

Abstract
The use of surfactants to attract dissolved ions to water surfaces and interfaces is an essential step in both solvent-based and solvent-free separation processes. We have studied the interactions of lanthanide ions in the aqueous subphase with monolayers of dihexadecyl phosphate at air-water interfaces. With heavier lanthanides (atomic number Z ≥ 65) in the subphase, the floating layer can be compressed to an area/molecule of about half the molecular cross section, indicating bilayer formation. X-ray fluorescence and reflectivity data support this conclusion. In the presence of lighter lanthanides (Z < 65), only monolayers are observed. Subphase-concentration-dependent studies using Er3+ (heavier) and Nd3+ (lighter) lanthanides show a stepwise progression, with ions attaching to the monolayer only when the solution concentration is >3 × 10-7 M. Above ∼10-5 M, bilayers form but only in the presence of the heavier lanthanide. Grazing incidence X-ray diffraction shows evidence of lateral ion-ion correlations in the bilayer structure but not in monolayers. Explicit solvent all-atom molecular dynamics simulations confirm the elevated ion-ion correlation in the bilayer system. This bilayer structure isolates heavier lanthanides but not lighter lanthanides from an aqueous solution and is therefore a potential mechanism for the selective separation of heavier lanthanides.

Abstract
BACKGROUND The optimal fluid strategy to prevent maternal hypotension during caesarean delivery remains unclear. This study aim was to compare the incidence of post-spinal anaesthesia hypotension in women receiving either colloid or crystalloid coload in the setting of prophylactic phenylephrine infusion during caesarean delivery. METHODS Healthy mothers undergoing elective caesarean delivery under spinal anaesthesia were randomised to receive a rapid intravenous coload with 6% hydroxyethyl starch 130/0.4 10 mL/kg (colloid group) or balanced crystalloid solution (Plasma Solution A) 10 mL/kg (crystalloid group) during spinal anaesthesia. All women had a prophylactic phenylephrine infusion initiated at 25 μg/min immediately after the subarachnoid block and titrated to systolic blood pressure using a standardised protocol. The primary outcome was the incidence of hypotension (systolic blood pressure <80% of baseline) until delivery. RESULTS The incidence of hypotension was 50% in the colloid group and 62% in the crystalloid group (absolute difference, -12% [95% CI -33% to 9%]; relative risk, 0.8 [95% CI 0.56 to 1.14]; P=0.314). No significant difference between groups was found in the number of hypotensive episodes (median 0.5 [IQR 0 to 1] vs 1 [0 to 2], P=0.132) or phenylephrine dose (675 [IQR 425 to 975] μg vs 750 [625 to 950] μg, P=0.109). The incidence of severe hypotension, symptomatic hypotension, bradycardia, nausea, and the neonatal outcomes were not significantly different. CONCLUSIONS This study found no benefit of colloid coload compared with crystalloid coload for preventing maternal hypotension in the presence of prophylactic phenylephrine infusion during caesarean delivery.

Abstract
BACKGROUND Inflammation plays critical roles at different stages of carcinogenesis and cancer progression. Several previous studies showed conflicting results for the predictive role of systemic inflammation markers in the detection of clinically significant prostate cancers (CSPCs). We aimed to determine the predictive roles of lymphocyte-to-monocyte (LMR) and eosinophil-to-lymphocyte ratios (ELR) in the detection of CSPC at standard 12-core transrectal ultrasound-guided prostate biopsy (12-core-TRUS-Bx) using our large-cohort database. METHODS Clinical and pathological data of a total of 1740 men, who underwent initial standard 12-core TRUS-Bx, were analyzed. LMR and ELR were calculated from the prebiopsy complete blood count. Definitions of CSPC, LMR, and ELR were "Gleason grade group ≥2," "the lymphocyte counts/the monocyte counts," and "the eosinophil counts/the lymphocyte counts," respectively. RESULTS Median (interquartile range) of serum prostate-specific antigen (PSA) level and prostatic volume before TRUS-Bx were 7.59 (5.02-13.12) ng/ml and 38.2 (29.0-52.9) ml, respectively. Benign prostatic lesions, clinically insignificant prostate cancers (CIPCs), and CSPCs were detected in 1179 (67.8%), 180 (10.3%), and 381 (21.9%) patients, respectively. The patients with CSPCs had older age, a higher prevalence of diabetes mellitus or hypertension, a higher rate of digital rectal examination abnormality, higher serum PSA level, lower serum testosterone level, and lower LMR than those with benign lesions or CIPCs. However, there was no difference in ELR among the three (benign lesions, CIPCs and CSPCs). In all the patients, multivariate regression analysis showed that lower LMR was an independent predictor of CSPCs compared with ELR. In the subset of men with prostate volume ≥39.3 ml, lower LMR was an independent predictor of CSPCs compared with ELR. In the subset of men with prostate volume <39.3 ml, men with lower LMR showed the tendency of having a higher probability of CSPCs without any statistical significance on the contrary to ELR. CONCLUSIONS Our data indicate that LMR can play an independent predictive role in the detection of CSPCs at initial 12-core-TRUS-Bx compared with ELR. The predictive role of the LMR appears to be significant for men with larger prostate volume rather than those with smaller prostate volume.

Abstract
We aim to investigate the significance of intravesical prostate protrusion (IPP) on the prognosis of non-muscle invasive bladder cancer (NMIBC) after the transurethral resection of bladder tumors (TURBT). For newly diagnosed NMIBC, we retrospectively analyzed the association between prognosis and IPP for at least a 5-year follow-up. A degree of IPP over 5 mm in a preoperative CT scan was classified as severe. The primary endpoint was recurrence-free survival, and the secondary endpoint was progression-free survival. The machine learning (ML) algorithm of a support vector machine was used for predictive model development. Of a total of 122 patients, ultimately, severe IPP was observed in 33 patients (27.0%). IPP correlated positively with age, BPH, recurrence, and prognosis. Severe IPP was significantly higher in the recurrence group and reduced in the recurrence-free survival group (p = 0.038, p = 0.032). Severe IPP independently increased the risk of intravesical recurrence by 2.6 times. The addition of IPP to the known oncological risk factors in the prediction model using the ML algorithm improved the predictability of cancer recurrence by approximately 6%, to 0.803. IPP was analyzed as a potential independent risk factor for NMIBC recurrence and progression after TURBT. This anatomical feature of the prostate could affect the recurrence of bladder tumors.

Abstract
We present a supercomputer-driven pipeline for in silico drug discovery using enhanced sampling molecular dynamics (MD) and ensemble docking. Ensemble docking makes use of MD results by docking compound databases into representative protein binding-site conformations, thus taking into account the dynamic properties of the binding sites. We also describe preliminary results obtained for 24 systems involving eight proteins of the proteome of SARS-CoV-2. The MD involves temperature replica exchange enhanced sampling, making use of massively parallel supercomputing to quickly sample the configurational space of protein drug targets. Using the Summit supercomputer at the Oak Ridge National Laboratory, more than 1 ms of enhanced sampling MD can be generated per day. We have ensemble docked repurposing databases to 10 configurations of each of the 24 SARS-CoV-2 systems using AutoDock Vina. Comparison to experiment demonstrates remarkably high hit rates for the top scoring tranches of compounds identified by our ensemble approach. We also demonstrate that, using Autodock-GPU on Summit, it is possible to perform exhaustive docking of one billion compounds in under 24 h. Finally, we discuss preliminary results and planned improvements to the pipeline, including the use of quantum mechanical (QM), machine learning, and artificial intelligence (AI) methods to cluster MD trajectories and rescore docking poses.

Abstract
Bacillus Calmette-Guérin (BCG) is recommended as the first-line treatment option for intermediate to high risk non-muscle invasive bladder cancer (NMIBC) by current clinical guidelines. However, despite the intravesical instillation of BCG, a significant proportion of patients with intermediate to high risk NMIBC develop intravesical recurrence. Moreover, the treatment of BCG-unresponsive NMIBC is currently challenging. There are no reliable treatment options for these patients with BCG-unresponsive NMIBC except radical cystectomy, which reported to show acceptable oncological outcomes. In this regards, reliable and safe non-invasive or less-invasive treatment options with acceptable oncological outcomes are awaited for the treatment of BCG-unresponsive NMIBC. The treatment of advanced or metastatic urothelial carcinoma has greatly advanced following the recent introduction of immunotherapeutic agents. These advancements have triggered an increasing interest in the use of immunotherapeutic agents for NMIBC, and especially for BCG-unresponsive NMIBC. The current review article aims to introduce and discuss the cutting-edge knowledge on the role of immunotherapy in BCG-unresponsive NMIBC and the currently available therapeutic strategies for its treatment. In addition, this article also summarizes the ongoing studies in this field.

Abstract
Improving adjuvant responses is a promising pathway to develop vaccines against some pathogens (e.g., HIV or dengue). One challenge in adjuvant development is modulating the inflammatory response, which can cause excess side effects, while maintaining immune activation and protection. No approved adjuvants yet have the capability to independently modulate inflammation and protection. Here, we demonstrate a method to limit inflammation while retaining and often increasing the protective responses. To accomplish this goal, we combined a partial selective nuclear factor kappa B (NF-kB) inhibitor with several current adjuvants. The resulting vaccines reduce systemic inflammation and boost protective responses. In an influenza challenge model, we demonstrate that this approach enhances protection. This method was tested across a broad range of adjuvants and antigens. We anticipate these studies will lead to an alternative approach to vaccine formulation design that may prove broadly applicable to a wide range of adjuvants and vaccines.

Abstract
OBJECTIVES To develop and validate a risk calculator for prostate cancer (PCa) and clinically significant PCa (csPCa) using explainable artificial intelligence (XAI). PATIENTS AND METHODS We used data of 3791 patients to develop and validate the risk calculator. We initially divided the data into development and validation sets. An extreme gradient-boosting algorithm was applied to the development calculator using five-fold cross-validation with hyperparameter tuning following feature selection in the development set. The model feature importance was determined based on the Shapley value. The area under the curve (AUC) of the receiver operating characteristic curve was analysed for each validation set of the calculator. RESULTS Approximately 1216 (32.7%) and 562 (14.8%) patients were diagnosed with PCa and csPCa. The data of 2843 patients were used for development, whereas the data of 948 patients were used as a test set. We selected the variables for each PCa and csPCa risk calculation according to the least absolute shrinkage and selection operator regression. The AUC of the final PCa model was 0.869 (95% confidence interval [CI] 0.844-0.893), whereas that of the csPCa model was 0.945 (95% CI 0.927-0.963). The prostate-specific antigen (PSA) level, free PSA level, age, prostate volume (both the transitional zone and total), hypoechoic lesions on ultrasonography, and testosterone level were found to be important parameters in the PCa model. The number of previous biopsies was not associated with the risk of csPCa, but was negatively associated with the risk of PCa. CONCLUSION We successfully developed and validated a decision-supporting tool using XAI for calculating the probability of PCa and csPCa prior to prostate biopsy.

Abstract
Purpose We investigated the possible association between preoperative bladder wall thickness (BWT) or detrusor wall thickness (DWT) and bladder outlet obstruction (BOO) based on urodynamic studies in men with symptomatic benign prostatic hyperplasia (BPH). Materials and Methods Data were prospectively collected from a BPH surgery database. A total of 196 men who underwent prostate vaporization for symptomatic BPH were included in this study. BWT and DWT were measured in the suprapubic area after uroflowmetry. Results No significant difference was noted in BWT and DWT in any patient according to the presence of BOO; however, subgroup analysis showed that BWT and DWT were significantly thicker in the obstruction group in men aged 70 years or older than in those under age 70 (BWT: 3.6+0.9 mm vs. 3.1+0.9 mm, p=0.022, DWT: 2.8±0.8 mm vs. 2.3±0.8 mm, p=0.007). In this older age group, the classification based on a BWT ≥4.0 mm showed 31% sensitivity, 87% specificity, and 65% diagnostic accuracy for the diagnosis of BOO, whereas DWT ≥3.0 mm showed 49% sensitivity, 82% specificity, and 69% diagnostic accuracy. Conclusions BWT and DWT were associated with BOO in men aged 70 years or older. Therefore, BWT and DWT will be a useful non-invasive parameter for deciding the management strategy for elderly men with symptomatic BPH. An appropriate measurement method should be established as soon as possible for further application of the relationship among BWT, DWT and BOO.

Abstract
This study aims to evaluate differences in the risk factors for biochemical recurrence (BCR) for radical prostatectomy stratified by degree of obesity, focusing on the surgical method used. All 3099 patients who underwent radical prostatectomy in two medical centres from January 2008 to March 2018 were retrospectively reviewed. Patients were divided into three groups based on body mass index: ‘normal’, ‘overweight’, and ‘obese’. Risk factors associated with biochemical recurrence were compared between different degrees of obesity. We analysed the contributing risk factors of BCR-free survival using univariate and multivariable Cox hazard models. There were 378 (12.2%) and 1815 (58.6%) patients in the ‘obese’ and ‘overweight’ groups, respectively. Accordingly, 1324 patients underwent retropubic radical prostatectomy (RRP), and 1775 underwent robotic-assisted laparoscopic prostatectomy (RALP). Multivariable analysis showed that patients who underwent RALP had significantly lower BCR free survival in the ‘overweight’ and ‘obese’ groups than those who underwent RRP, with adjusted hazard ratios of 0.75 (95% CI 0.59–0.95, p-value = 0.01) and 0.55 (95% CI 0.33–0.90, p-value = 0.02), respectively. The degree of obesity was not directly associated with BCR-free survival. Robotic prostatectomy showed greater benefits in BCR-free survival than open prostatectomy in the ‘overweight’ and ‘obese’ groups.

Abstract
BACKGROUND We evaluated the optimal high-density lipoprotein cholesterol level for benign prostatic hyperplasia (BPH) prevention in men not taking statin medication using a large historical cohort. METHODS We initially selected 130 454 men who underwent health checkups in 2009 from the National Health Information Database of the National Health Insurance Service. After excluding 36 854 men with BPH in 2009, and 45 061 men for statin use, 48 539 men were ultimately included in the analysis. A Kaplan-Meier analysis and multivariable Cox regression analysis was performed to assess the optimal high-density lipoprotein cholesterol level for preventing BPH. RESULTS High-density lipoprotein cholesterol levels were less than 40 mg/dL in 7431 (15.3%) men, 40 to 49 in 15 861 (32.7%), 50 to 59 in 15 328 (27.5%), and greater than or equal to 60 in 11 919 (24.6%). The overall cumulative incidence of BPH was 4.4%, 8.7%, 13.0%, and 17.8% at the 1-, 2-, 3-, and 4-year follow-up periods, respectively. In multivariable analysis, high-density lipoprotein greater than or equal to 60 mg/dL were significantly associated with a decreased incidence of BPH, as were age, residence, income, body mass index, diabetes, hypertension, triglyceride, and increased annual clinic visits, especially in men in their 40s. CONCLUSION Elevated serum high-density lipoprotein cholesterol levels were negatively associated with BPH incidence. In addition, maintaining high-density lipoprotein greater than or equal to 60 mg/dL was associated with a decreased BPH incidence compared with high-density lipoprotein less than 40 mg/dL, especially in men in their 40s.

Abstract
BACKGROUND Guidelines for follow-up of patients with melanoma are based on limited evidence. OBJECTIVES To guide skin surveillance, we developed a risk prediction model for subsequent primary melanomas, using demographic, phenotypical, histopathological, sun exposure and genomic risk factors. METHODS Using Cox regression frailty models, we analysed data for 2613 primary melanomas from 1266 patients recruited to the population-based Genes, Environment and Melanoma study in New South Wales, Australia, with a median of 14 years' follow-up via the cancer registry. Discrimination and calibration were assessed. RESULTS The median time to diagnosis of a subsequent primary melanoma decreased with each new primary melanoma. The final model included 12 risk factors. Harrell's C-statistic was 0·73 [95% confidence interval (CI) 0·68-0·77], 0·65 (95% CI 0·62-0·68) and 0·65 (95% CI 0·61-0·69) for predicting second, third and fourth primary melanomas, respectively. The risk of a subsequent primary melanoma was 4·75 times higher (95% CI 3·87-5·82) for the highest vs. the lowest quintile of the risk score. The mean absolute risk of a subsequent primary melanoma within 5 years was 8·0 ± SD 4.1% after the first primary melanoma, and 46·8 ± 15·0% after the second, but varied substantially by risk score. CONCLUSIONS The risk of developing a subsequent primary melanoma varies considerably between individuals and is particularly high for those with two or more primary melanomas. The risk prediction model and its associated nomograms enable estimation of the absolute risk of subsequent primary melanoma, on the basis of on an individual's risk factors, and can be used to tailor surveillance intensity, communicate risk and provide patient education. What's already known about this topic? Current guidelines for the frequency and length of follow-up to detect new primary melanomas in patients with one or more previous primary melanomas are based on limited evidence. People with one or more primary melanomas have, on average, a higher risk of developing another primary invasive melanoma, compared with the general population, but an accurate way of estimating individual risk is needed. What does this study add? We provide a comprehensive risk prediction model for subsequent primary melanomas, using data from 1266 participants with melanoma (2613 primary melanomas), over a median 14 years' follow-up. The model includes 12 risk factors comprising demographic, phenotypical, histopathological and genomic factors, and sun exposure. It enables estimation of the absolute risk of subsequent primary melanomas, and can be used to tailor surveillance intensity, communicate individual risk and provide patient education.

Abstract
Solution-processed metal grid transparent conductors with low sheet resistance, high optical transmittance and good mechanical flexibility have great potential for use in flexible optoelectronic devices. However, there are still remaining challenges to improve optoelectrical properties and electromechanical stability of the metallic structures due to random loose packings of nanoparticles and the existence of many pores. Here we introduce a selective multi-nanosoldering method to generate robust metallic layers on the thin metal grid structures (< a thickness of 200 nm), which are generated via self-pining assisted direct inking of silver ions. The selective multi-nanosoldering leads to lowering the sheet resistance of the metal grid transparent conductors, while keeping the optical transmittance constant. Also, it reinforces the electromechanical stability of flexible metal grid transparent conductors against a small bending radius or a repeated loading. Finally, organic light-emitting diodes based on the flexible metal grid transparent conductors are demonstrated. Our approach can open a new route to enhance the functionality of metallic structures fabricated using a variety of solution-processed metal patterning methods for next-generation optoelectronic and micro/nanoelectronic applications.

Abstract
Background We assessed the effect of biopsy location on the prostate cancer detection and clinically significant prostate cancer. Methods A total of 2774 patients with 12‐core prostate transrectal ultrasound‐guided prostate biopsy were included for per core analysis. Multivariate Cox regression analysis was performed to evaluate the effect of the location of biopsy on the prostate cancer and clinically significant prostate cancer detection. Results Prostate cancer was found in 775 patients (27.9%) and 576 prostate cancer patients (20.8%) were found to be clinically significant. The core length (P = .043), tumor length (P < .001), and % tumor length (P < .001) were significantly different according to the biopsy location. The detection rates for prostate cancer and clinically significant prostate cancer differed significantly according to the location of biopsy. Multivariate analysis revealed that the apical core was significantly related with increased detection of prostate cancer and clinically significant prostate cancer. The lateral core, in addition to apical core, was found to be significantly related with increased detection rates of prostate cancer and clinically significant prostate cancer in men with prostate‐specific antigen <10 ng/mL. Conclusions More in‐depth discussions on the location of standard 12‐core prostate biopsy are considered necessary. Apical core and lateral core biopsies may be helpful, especially in patients with prostate‐specific antigen ˂10 ng/mL if additional biopsies are planned following findings of no target lesions on imaging studies.

Abstract
Purpose We evaluated the comparative effect of miniaturized percutaneous nephrolithotomy (mini-PCNL) and retrograde intrarenal surgery (RIRS) on perioperative kidney function by use of diethylenetriamine penta-acetic acid (99mTc-DTPA) scintigraphy and identified significant predictors associated with deterioration or amelioration of renal function after surgery. Materials and Methods All 70 patients who underwent mini-PCNL or RIRS between 2012 and 2016 were monitored by 99mTc-DTPA scintigraphy preoperatively. Patients with abnormal renal function were monitored from 3 to 12 months postoperatively. Logistic regression analyses were conducted to estimate the predictors of aggravated renal dysfunction and improvement. Results The difference in preoperative renal function between the contralateral and the operative side was >10% in 57 patients (81.4%). Among those in the group with abnormal renal function, 40 (70.2%), 10 (17.5%), and 7 (12.3%) patients showed stability, deterioration, and improvement in renal function at postoperative year 1, respectively. Functional changes did not differ according to the type of surgery. A high level of serum creatinine preoperatively (p=0.060) and a history of previous stone procedures (p=0.051) showed borderline significance for prediction of deterioration in renal function. Conclusions RIRS and mini-PCNL had similar effects and favorable outcomes on renal function during a 1-year follow-up period. High baseline serum creatinine levels and a history of procedures warrant careful attention.

Abstract
OBJECTIVE The aim of this study was to evaluate the feasibility of including patients with biopsy Gleason score (bGS) 3 + 4 prostate cancer in an active surveillance (AS) protocol. METHODS A total of 615 patients underwent a radical prostatectomy and satisfied the following requirements: prostate-specific antigen ≤10 ng/dL, clinical stage T1c or T2a, 2 or fewer positive biopsy cores, and bGS 6 or 3 + 4 prostate cancer. The patients were divided into two groups according to their bGS (bGS 6 group, n =534; bGS 3 + 4 group, n = 81). RESULTS The adverse pathological features were significantly higher in the bGS 3 + 4 group (16.7 vs. 49.4%, p< 0.001). Biochemical recurrence (BCR)-free survival was also significantly lower in this group (p < 0.001). In a multivariate analysis, clinical stage (odds ratio [OR] 2.026, p =0.007), maximum percentage of biopsy core involvement (OR 1.015, p = 0.014), and bGS (OR 1.913, p = 0.030) were independent risk factors for adverse pathological features. However, the bGS was the only variable to forecast BCR (hazard ratio 3.567, p < 0.001). CONCLUSIONS A bGS 3 + 4 was the leading risk factor for a worse postoperative prognosis. Therefore, patients with a bGS 3 + 4 are not appropriate candidates for AS.

Abstract
This study was aimed to compare serial long-term postoperative changes in quality-of-life (QoL) between photoselective-vaporization (PVP) using 120W-High-Performance-System and holmium-laser-enucleation (HoLEP) in benign-prostatic-hyperplasia (BPH) patients and to identify factors influencing the QoL improvement at the short-term, mid-term and long-term follow-up visits after surgery. We analyzed 1,193 patients with a baseline QoL-index ≥2 who underwent PVP (n = 439) or HoLEP (n = 754). Surgical outcomes were serially compared between the two groups at up to 60-months using the International-Prostatic-Symptom-Score (I-PSS), uroflowmetry, and serum PSA. We used logistic regression analysis to identify predictors of QoL improvement (a reduction in the QoL-index ≥50% compared with baseline) at the short-term (12-months), mid-term (36-months), and long term (60-months) follow-up after surgery. In both groups, the QoL-index was decreased throughout the entire follow-up period compared with that at baseline. There were no significant differences in postoperative changes from the baseline QoL-index between the two groups during the 48-month follow-up, except at 60-months. The degree of improvement in QoL at 60-months after HoLEP was greater than that after PVP. A lower baseline storage-symptom-subscore and a higher bladder-outlet-obstruction-index (BOOI) were independent factors influencing QoL improvement at the short-term. No independent factor influences QoL improvement at the mid- or long-term.

Abstract
Rare earths, which are fundamental components of modern technologies, are often extracted from aqueous solutions using surfactants at oil-water interfaces. Heavier lanthanides are more easily extracted, even though all lanthanides are chemically very similar. Using x-ray fluorescence measurements and theoretical arguments, we show that there is a sharp bulk-concentration-dependent transition in the interfacial adsorption of cations from aqueous solutions containing Er^{3+} or Nd^{3+} in contact with a floating monolayer. The threshold bulk concentration of erbium (Z=68) is an order of magnitude lower than that of neodymium (Z=60), and erbium is preferentially adsorbed when the solution contains both ions. This implies that elemental selectivity during separation originates at the surfactant interface. Electrostatic effects arising from the interface dielectric mismatch, ionic correlations, and sizes of the ions explain the sharp adsorption curve and selectivity.

Abstract
OBJECTIVES To investigate the impact of preoperative detrusor underactivity (DU) on serial treatment outcomes over the course of 5 years after photovaporization (PV) or holmium laser enucleation (HoLEP) in patients with benign prostatic hyperplasia (BPH), to compare its impact after PV vs HoLEP, and to identify predictors of long-term lower urinary tract symptoms (LUTS) improvement. MATERIALS AND METHODS This study involved 245 patients with BPH who had complete 5-year follow-up data (PV using 120W-HPS, n = 143, HoLEP, n = 102), grouped as follows: PV-HPS-DU(+), n = 114; PV-HPS-DU(-), n = 29; HoLEP-DU(+), n = 56; and HoLEP-DU(-), n = 46. Bladder contractility index (BCI) < 100 was regarded as DU. Serial treatment outcomes for the International Prostate Symptom Score (IPSS) questionnaire, uroflowmetry and serum PSA level at 6 months, and at 1, 2, 3, 4 and 5 years after surgery, were compared among the groups. LUTS improvement was defined as a reduction in total IPSS of ≥50% relative to baseline. RESULTS Improvement in total IPSS, quality of life (QoL) index and post-void residual urine volume (PVR) in the PV-HPS-DU(+) and PV-HPS-DU(-) groups were maintained up to 5 years after PV, except for maximum urinary flow rate (Qmax ) and bladder voiding efficiency. In the HoLEP-DU(+) and HoLEP-DU(-) groups, improvements in all outcome variables were maintained up to 5 years after HoLEP. Deteriorations in subtotal voiding symptom score, total IPSS and Qmax with time during the long-term period after surgery were more pronounced in the PV-HPS-DU(+) and HoLEP-DU(+) groups than in the PV-HPS-DU(-) and HoLEP-DU(-) groups. Reductions in subtotal voiding symptom score, total IPSS, QoL index, and serum PSA were greater in the HoLEP-DU(+) group than in the PV-HPS-DU(+) group throughout follow-up. The type of surgery (HoLEP vs PV) and higher baseline BCI were independent predictors of LUTS improvement at 5 years after surgery. CONCLUSION Generally, improvement of micturition symptoms, QoL and PVR in patients with DU appears to be maintained up to 5 years after PV or HoLEP. Deterioration of voiding symptoms and urinary flow rate at long-term follow-up visits after PV or HoLEP was more pronounced in patients with LUTS/BPH with DU than in those without DU. Patients with BPH with DU may benefit from more complete removal of prostatic adenoma by HoLEP and greater baseline bladder contractility in terms of micturition symptoms and QoL.

Abstract
PURPOSE To estimate the effect of metabolic syndrome (MetS) on the prevalence of prostate cancer using a large retrospective cohort with a 5-year follow-up duration. METHODS National Health Insurance Service health checkup cohort was used for the study. In total, 130,342 men included in the health checkup cohort in 2009 were divided into two groups according to the presence of prostate cancer. The prevalence of prostate cancer from 2009 to 2013 was cumulatively calculated from 2003. A generalized estimating equation was used to assess the effect of MetS and its component on the prevalence of prostate cancer after adjusting for other variables. RESULTS Prostate cancer was present in 2369 men (1.8%) in 2009. The prevalence of prostate cancer was significantly higher in patients with MetS than in those without MetS throughout the entire follow-up duration. Multivariable analysis showed that in addition to year at evaluation and age, the presence of MetS was associated with an increased prevalence of prostate cancer. Alcohol consumption and smoking levels were negatively associated with the prevalence of prostate cancer. Among MetS components, decreased high density lipoprotein (HDL)-cholesterolemia and central obesity were associated with an increased prevalence of prostate cancer after adjusting for other variables. CONCLUSION MetS and its components, especially decreased HDL-cholesterol levels and central obesity, were related to the increased prevalence of prostate cancer. Preventing MetS, maintaining high HDL-cholesterol level, and maintaining low waist circumference might be useful ways for decreasing the prevalence of prostate cancer.

Abstract
Purpose To assess the utility of voided volume on initial uroflowmetry in predicting symptom severity in men with storage symptoms. In addition, we assessed the probability that men would show a voided volume of ≥ 150 mL on uroflowmetry if the examination is repeated. Methods Between 2016 and 2017, 352 men with storage symptoms were enrolled in the study. The patients completed the frequency–volume chart and were divided into four groups based on the voided volume. A multivariate analysis was performed to determine the variables affecting voided volume. Results The VV was < 68.8 mL in 88 patients (25.0%), 68.9–150 in 89 (25.3%), 150–250 in 87 (24.7%), and ≥ 250 in 88 (25.0%) patients. Although the International Prostate Symptom Score did not differ among the groups, the storage subscore was significantly higher in patients with decreased voided volume (p = 0.010). The total number of voids was greater in patients with decreased voided volume (p < 0.001), as was the number of nocturnal voids (p = 0.007). The maximum voided volume (p < 0.001) and 24-h urine output (p = 0.003) decreased as voided volume decreased. The proportions of patients with a mean daytime urine output ≥ 150 mL were 30.1%, 43.0%, 64.7%, and 66.7% in each group, respectively (p < 0.001). Older age and decreased maximum voided volume significantly affected the voided volume on initial uroflowmetry. Conclusions A decreased voided volume on initial uroflowmetry may be a sign of severe storage symptoms in men. This finding is related to older age and decreased functional capacity. In these patients, it is better to perform a careful clinical assessment to diagnose and treat overactive bladder.
