Prediction of preoperative peritoneal cancer index for pseudomyxoma peritonei by multiple linear regression analysis.

Background: The aim of the present study was to establish a predictive model to predict the peritoneal cancer index (PCI) preoperatively in patients with pseudomyxoma peritonei (PMP).

Methods: A total of 372 PMP patients were consecutively included from a prospective follow-up database between 1 June 2013 and 1 June 2023. Nine potential variables, namely, gender, age, Barthel Index (BAI), hemoglobin (Hb), albumin (Alb), D-dimer, carcinoembryonic antigen (CEA), carbohydrate antigen 125 (CA 125), and CA 19-9, were estimated using multiple linear regression (MLR) analysis with a stepwise selection procedure.

Detecting Clinically Relevant Topological Structures in Multiplexed Spatial Proteomics Imaging Using TopKAT.

Novel multiplexed spatial proteomics imaging platforms expose the spatial architecture of cells in the tumor microenvironment (TME). The diverse cell population in the TME, including its spatial context, has been shown to have important clinical implications, correlating with disease prognosis and treatment response. The accelerating implementation of spatial proteomic technologies motivates new statistical models to test if cell-level images associate with patient-level endpoints.

Contrast-associated acute kidney injury in patients with diabetes mellitus following elective percutaneous coronary intervention: Insights from an iodixanol-acute kidney injury registry study.

Background: Patients with diabetes mellitus (DM) are particularly susceptible to contrast-associated acute kidney injury (CA-AKI). However, few studies have evaluated CA-AKI stages in patients with DM following elective percutaneous coronary intervention (PCI) with iodixanol.

Methods: Patients with DM who underwent elective PCI in 8 Chinese hospitals from May 2020 to November 2021 were prospectively enrolled in the Iodixanol-Acute Kidney Injury Registry (No.

Influence of the wet-ear state on the outcomes of tympanic membrane repair under ear endoscopy: a prospective case-control study.

Background: To prospectively determine whether tympanoplasty for tympanic membrane perforation (TMP) in wet ears impacts recovery.

Methods: We prospectively enrolled 32 TMP patients (2021-2023) and divided them into the wet-ear (14 patients) and dry-ear groups (18 patients), according to the presence of middle-ear secretions/edema. All patients underwent high-resolution thin-slice computed tomography, ear endoscopy, and pure tone audiometry.
