This study evaluated the diagnostic performance of plasma biomarkers for Alzheimer's disease (AD) using an automated platform. In a cohort of 74 consecutive patients, plasma p-Tau181 levels were significantly higher in AD compared to non-AD groups and showed correlation with cerebrospinal fluid biomarkers. Plasma p-Tau181 demonstrated high diagnostic accuracy for AD, with an area under the curve of 0.854. The findings suggest that plasma biomarkers, particularly p-Tau181, could improve the accessibility and efficiency of AD diagnostics in clinical settings, offering a less invasive and cost-effective alternative to traditional methods.

Background: Avenanthramides (AVAs) and Avenacosides (AVEs) are unique to oats (Avena Sativa) and may serve as biomarkers of oat intake. However, information regarding their validity as food intake biomarkers is missing. We aimed to investigate critical validation parameters such as half-lives, dose-response, matrix effects, relative bioavailability under single dose, and in relation to the abundance of Feacalibacterium prausnitzii, and under repeated dosing, to understand the potential applications of AVAs and AVEs as biomarkers of oat intake.

Purpose: Early detection of HPV-associated oropharyngeal cancer (HPV+OPSCC), the most common HPV cancer in the United States, could reduce disease-related morbidity and mortality, yet currently, there are no early detection tests. Circulating tumor HPV DNA (ctHPVDNA) is a sensitive and specific biomarker for HPV+OPSCC at diagnosis. It is unknown if ctHPVDNA is detectable prior to diagnosis, and thus it's potential as an early detection test.

Background: Sarcomas are rare cancer with a heterogeneous group of tumors. They affect both genders across all age groups and present significant heterogeneity, with more than 70 histological subtypes. Despite tailored treatments, the high metastatic potential of sarcomas remains a major factor in poor patient survival, as metastasis is often the leading cause of death.

As plasma biomarkers like p-tau217 move towards clinical use in Alzheimer's disease (AD), it is important to understand how kidney function may influence their accuracy. Even mild chronic kidney disease (CKD) can alter biomarker levels, potentially impacting test performance. While accounting for renal function may improve specificity, it could reduce sensitivity without greatly changing overall diagnostic accuracy.

Neutrophils play a complex role in the pathogenesis of chronic liver disease and have been linked to both liver damage and injury resolution. Recent reports propose that neutrophils drive liver injury and fibrosis through the formation of neutrophil extracellular traps (NETs). This study tests the hypothesis that the enzyme peptidyl arginine deiminase-4 (PAD4) drives NET formation and liver fibrosis in experimental chronic liver injury.
