BSAVA Petsavers Article: Validation of an ELISA assay for measurement of the metabolite of serotonin, 5‐hydroxyindole acetic acid (5‐HIAA), in canine urine

Journal of Small Animal Practice, EarlyView.
Objectives Serotonin (5‐hydroxytryptophan), implicated in a number of canine diseases, has a very short half‐life in the serum. Urine concentration of its breakdown product 5‐hydroxyindole acetic acid after an 8 hour fast is a more reliable measure of circulating serotonin in humans.

Assessing the exercise‐related kinetics of circulating cell‐free DNA, circulating tumour DNA, DNase I activity and cytokines in patients with solid tumours: A pilot study

Experimental Physiology, EarlyView.
Abstract Circulating cell‐free DNA (cfDNA), circulating tumour DNA (ctDNA) and inflammatory cytokines have prognostic and predictive value in oncology. However, the effects of acute exercise on cfDNA levels are unknown. Here, we explore the kinetics of cfDNA, ctDNA and cytokines upon an incremental exercise test in a pilot cohort of cancer patients ...

High Soluble Tumor Necrosis Factor Receptor 2 in Serum Is Associated With Inferior Overall Survival Across Major Lymphoma Subtypes

American Journal of Hematology, Volume 101, Issue 6, Page 1388-1397, June 2026.
ABSTRACT Soluble tumor necrosis factor receptor 2 (sTNFR2) is a member of the TNF superfamily whose normal bodily distribution is largely limited to low level expression on lymphoid cells. It has emerged as an important inducible receptor that activates a signaling pathway for cancer growth.

Real‐world prevalence of PD‐L1 positivity in early‐stage/metastatic triple‐negative breast cancer: primary results and pathology insights from the global retrospective observational VANESSA study

Histopathology, Volume 88, Issue 7, Page 1373-1384, June 2026.
In the real‐world VANESSA study in triple‐negative breast cancer, PD‐L1‐positive prevalence was 38% in early‐stage and 20% in metastatic tumours, lower than in prospective trials. The lower prevalence in smaller versus larger tissue samples and by local versus central assessment underlines the importance of robust PD‐L1 testing to determine eligibility
