Echocardiographic classification of dogs with aortic stenosis: potential utility of a novel staging system.

Introduction: Severity of aortic stenosis (AS) in humans is classified using a staging system based on two-dimensional echocardiographic changes, which considers the extent of global cardiac damage. Currently, classification of canine AS is based on trans-aortic pressure gradient (PG) alone. This study aimed to retrospectively classify dogs with AS based on an adapted human staging system, exploring feasibility of classification and the association between stage and features such as PG and clinical signs.

Depletion of conventional CD4 T cells is required for robust priming and dissemination of tumor antigen-specific CD8 T cells in the setting of anti-CD4 therapy.

Background: Overcoming immune suppression is a major barrier to eliciting potent CD8 T cell responses against cancer. Treatment with anti-CD4 monoclonal antibody is an effective means for eliminating CD4Foxp3 regulatory (Treg) cells in preclinical models and has also demonstrated efficacy in early clinical trials. However, the underlying basis for treatment efficacy, more specifically the implications of codepleting other CD4-expressing cell compartments in tumor-bearing hosts, is not well understood.

Multiplatform metabolomic interlaboratory study of a whole human stool candidate reference material from omnivore and vegan donors.

Introduction: Human metabolomics has made significant strides in understanding metabolic changes and their implications for human health, with promising applications in diagnostics and treatment, particularly regarding the gut microbiome. However, progress is hampered by issues with data comparability and reproducibility across studies, limiting the translation of these discoveries into practical applications.

Objectives: This study aims to evaluate the fit-for-purpose of a suite of human stool samples as potential candidate reference materials (RMs) and assess the state of the field regarding harmonizing gut metabolomics measurements.

A Case of Metastatic Seminoma Mimicking a Primary Pancreatic Tumor.

Metastatic seminoma to the pancreas is exceedingly rare, with few reported cases in medical literature. We present a case of a 66-year-old male, six years post-remission from testicular seminoma, who presented with obstructive jaundice and a pancreatic mass mimicking primary malignancy. Diagnostic workup including endoscopic ultrasound-guided biopsy confirmed metastatic seminoma.
