Optimising urinary catecholamine metabolite diagnostics for neuroblastoma [PDF]

open access: yes, 2023
INTRODUCTION: The analysis of urinary catecholamine metabolites is a cornerstone of neuroblastoma diagnostics. Currently, there is no consensus regarding the sampling method, and variable combinations of catecholamine metabolites are being used.

Catecholamine metabolites in neuroblastoma patients [PDF]

open access: yes, 2019
Neuroblastoma is a paediatric malignancy of the developing sympathetic nervous system that is characterised by increased production and excretion of catecholamine metabolites such as homovanillic acid (HVA) and vanillylmandelic acid (VMA).

Dietary flavonols contribute to false-positive elevation of homovanillic acid, a marker of catecholamine-secreting tumours [PDF]

open access: yes, 2011
Background: Urinary homovanillic acid (HVA) measurement is used routinely as a marker of the first test for the screening of catecholamine-secreting tumors and dopamine metabolism, but generates a large number of false-positive results.

Behavioral Response to Catecholamine Depletion in Individuals With Schizophrenia and Healthy Volunteers [PDF]

open access: yes, 2023
BACKGROUND AND HYPOTHESIS Dysfunction of the dopamine system is the leading neurobiological hypothesis of schizophrenia. In this study, we tested this hypothesis in the context of aberrance salience theory of delusions using catecholamine depletion ...

Association between Pre-Existing Long-Term β-Blocker Therapy and the Outcomes of Sepsis-Associated Coagulopathy: A Retrospective Study

open access: yesMedicina, 2022
Background and Objectives: Previous studies have suggested that long-term β-blocker therapy before sepsis is associated with reduced mortality. Sepsis-associated coagulopathy (SAC) remains a common complication in patients with sepsis and is associated ...

Catecholamines in neuroblastoma: Driver of hypertension, or solely a marker of disease?

open access: yesCancer Reports, 2022
Background Neuroblastoma is a common solid tumor of childhood and is often associated with hypertension. Potential etiologies contributing to hypertension include renal compression, pain, volume overload, and catecholamine secretion. Cases We completed a
