Di-(2-ethylhexyl) phthalate (DEHP) is widely utilized as a plasticizer in industrial manufacturing to enhance the durability and flexibility of plastics. Studies have depicted that DEHP exposure may be associated with multiple cancers, including colorectal, liver and prostate cancer. However, the effects and underlying mechanisms of DEHP on bladder cancer progression remain unspecific. In this work, we explored the correlation between DEHP exposure and bladder cancer through comprehensive analysis. A total of 172 differentially expressed DEHP-related genes (DEDRGs) were screened based on the CTD and TCGA database. In addition, a new prognostic model related to DEHP was developed, which had excellent predictive power for bladder cancer prognoses. Molecular docking techniques were employed to assess the binding affinity of mono(2-ethylhexyl) phthalate (MEHP) to crucial proteins. Lastly, both in vitro and in vivo experiments, along with RNA sequencing, were conducted to elucidate the biological roles and mechanisms of MEHP in bladder cancer. Several new insights into the role of DEHP/MEHP in bladder cancer were given in this study, as well as an awareness of the association between environmental toxicants and cancer progression.

Purpose: This study aims to elucidate the role of pituitary adenylate cyclase-activating polypeptide (PACAP) in Hunner-type Interstitial Cystitis (HIC) and evaluate its potential as a therapeutic target.
Methods: Bladder tissue samples were obtained from HIC patients and normal bladder tissue from bladder cancer patients. PACAP expression was assessed through immunohistochemistry.

Including sensor information in medical interventions aims to support surgeons to decide on subsequent action steps by characterizing tissue intraoperatively. With bladder cancer, an important issue is tumor recurrence because of failure to remove the entire tumor. Impedance measurements can help to classify bladder tissue and give the surgeons an indication on how much tissue to remove.

Introduction: Bowel regimens (BR) before radical cystectomy (RC) are currently not recommended by Enhanced Recovery After Surgery (ERAS) protocols, as prior studies have shown BRs lead to worsened outcomes. However, many of those studies have used historic literature before recent surgical advancements such as minimally invasive RC and have not investigated the impact BRs have by type of urinary diversion. Our goal is to determine the outcomes of preoperative BR in patients undergoing RC based on diversion type using a modern patient cohort.

Preoperative detection of muscle-invasive bladder cancer (MIBC) remains a great challenge in practice. We aimed to develop and validate a deep Vesical Imaging Network (ViNet) model for the detection of MIBC using high-resolution Tweighted MR imaging (hrTWI) in a multicenter cohort. ViNet was designed using a modified 3D ResNet, in which, the encoder layers were pretrained using a self-supervised foundation model on over 40,000 cross-modal imaging datasets for transfer learning, and the classification modules were weakly supervised by an experiential knowledge-domain mask indicated by a nnUNet segmentation model.

Purpose: Bladder preservation therapy in combination with atezolizumab and radiation therapy (BPT-ART) trial, which was a multicenter, open-label, single-arm phase II study, showed a promisingly high interim clinical complete response (cCR) rate of 84.4% (38/45). In the present study, we aimed to identify potential tissue biomarkers for achieving cCR via BPT-ART.
