Background: The existence of sociodemographic disparities in pancreatic cancer has been well-studied but how these disparities have changed over time is unclear. The purpose of this study was to longitudinally assess patient management in the context of sociodemographic factors to identify persisting disparities in pancreatic cancer care.

Methods: Using the National Cancer Database, patients diagnosed with pancreatic ductal adenocarcinoma from 2010 to 2017 were identified.

Introduction: Prognostic markers for overall survival (OS) in resected pancreatic ductal adenocarcinoma (PDAC) are well-established but remain unclear following neoadjuvant therapy (NAT). This systematic review and meta-analysis aimed to determine factors associated with OS following NAT in resected PDAC.

Methods: The PubMed, Embase, Scopus, Web of Science, and Cochrane CENTRAL databases were systematically searched from inception till May 2024.

The literature regarding surgical repair of urethral prolapse in dogs is limited and associated with a high recurrence rate. We hypothesized that combined resection and anastomosis (R&A) with urethropexy would be associated with less recurrence of urethral prolapse compared with R&A alone. Medical records of dogs managed surgically for urethral prolapse were reviewed (2013-2023) from three tertiary care hospitals.

Background And Aim: Intraductal papillary mucinous neoplasm (IPMN)-derived pancreatic ductal adenocarcinoma (PDAC) management is generally extrapolated from pancreatic intraepithelial neoplasia (PanIN)-derived PDAC guidelines. However, these are biologically divergent, and heterogeneity further exists between tubular and colloid subtypes.

Methods: Consecutive upfront surgery patients with PanIN-derived and IPMN-derived PDAC were retrospectively identified from international centers (2000-2019).
