: Previous studies focused on food as the trigger of a migraine attack did not consider polyamines as possible activators and sensitizers of the trigeminal-vascular system through their interaction with NMDA glutamate receptors. Therefore, this study aimed to assess serum levels of nine polyamines and to evaluate their role as possible triggers and crisis maintainers in episodic and chronic migraine patients. : The study included 50 patients with episodic migraine (EM), 50 patients with chronic migraine (CM) and 50 healthy controls (HC). Serum levels of nine polyamines have been determined by Liquid Chromatography tandem Mass Spectrometry. Specifically, agmatine, spermidine, spermine, putrescine, cadaverine, arginine, ornithine, citrulline and lysine levels were studied. : Agmatine serum levels resulted reduced in EC patients with respect to CM and HC. Compared to HC subjects, serum levels of spermine and spermidine were statistically significantly increased both in CM and EM patients. : The authors suggest that alterations of polyamines levels might contribute to the understanding of migraine external activation and help to clarify the potential role of NMDA receptor polyamines site antagonists in migraine treatment.

Association of Albumin-To-Creatinine Ratio With Diabetic Retinopathy Among US Adults (NHANES 2009-2016).

Objective: This study investigates the relationship between the albumin-to-creatinine ratio and diabetic retinopathy (DR) in US adults using NHANES data from 2009 to 2016. This study assesses the predictive efficacy of the urinary serum albumin-to-creatinine ratio (UACR/SACR Ratio) against traditional biomarkers such as the serum albumin-to-creatinine ratio (SACR) and urinary albumin-to-creatinine ratio (UACR) for evaluating DR risk. Additionally, the study explores the potential of these biomarkers, both individually and in combination with HbA1c, for early detection and risk stratification of DR.

Objectives: To evaluate the predictive ability of furosemide stress test (FST), serum and urine cystatin-C in identifying progressive acute kidney injury (AKI) and the need for kidney replacement therapy (KRT).
Methods: Children aged one month to 18 y admitted in the pediatric intensive care unit (PICU) with Kidney Diseases Improving Global Outcomes (KDIGO) stage-1/2 AKI were enrolled. FST and serum and urine cystatin-C levels were performed and analyzed.
Circulating chemokine levels and receptor polymorphisms have potential as biomarkers for fibrosis stages in patients with chronic hepatitis C infection.

Background: Chemokines and their receptors, which regulate lymphoid organ development and immune cell trafficking, are integral to the mechanisms underlying viral control, hepatic inflammation, and liver damage in chronic hepatitis C (CHC) infection. This study explores the potential relationship between serum chemokine levels/polymorphisms and hepatitis C infection in affected individuals, with a particular focus on their utility as biomarkers across different stages of fibrosis.
Methods And Results: Serum levels of the chemokines CXCL11, CXCL12, and CXCL16 were measured in patients with mild/moderate and advanced fibrosis due to CHC, as well as in healthy controls, using the ELISA method.

Metabolomics provide a promising tool for understanding dementia pathogenesis and identifying novel biomarkers. This study aimed to identify amino acid biomarkers for Alzheimer's Disease (AD) and Vascular Dementia (VD). By amino acid metabolomics, the concentrations of amino acids were determined in the serum of AD and VD patients as well as age-matched healthy controls.
