Background: The correlation between Alzheimer's disease (AD) and the glucose-triglyceride (TyG) index remains undetermined.

Objective: This study aimed to investigate the relationship between the TyG index and AD, as well as the relationship between the TyG index and cerebrospinal fluid (CSF) AD biomarkers and cognition.

Methods: Six hundred twenty-eight non-dementia participants were included. The TyG index, pathological markers, and cognitive measures were studied using multiple linear regression. Also calculated using a multivariate Cox regression model were the hazard ratio (HR) and its 95% confidence interval (CI). Ten thousand bootstrap iterative causal mediation analyses were performed to investigate the potential mediating effect of AD pathology on cognition.

Results: The TyG index was linked to CSF AD biomarkers (β= 0.880; β= -0.674; β= -0.884; β= 1.764; β= 1.554; β= -0.210) and cognitive measurements (β= 0.570; β= 0.535; β= -0.789). Mediation analysis revealed that the TyG index may influence cognition via CSF AD biomarkers, including Aβ, tau, and pTau. Furthermore, each 1-unit increase in TyG index was associated with a 29.5% reduction in the risk of incident AD.

Conclusions: A delayed rate of cognitive decline and a reduced risk of AD were found to be correlated with higher levels of the TyG index, but this does not mean increasing TyG index levels is beneficial for health. Through AD pathology, the TyG index may influence AD and cognitive changes.

Background: Pediatric CNS infections have been identified as a global health problem, associated with an increased death rate and fatal consequences. Pentraxin 3 (PTX3) is an acute-phase mediator that increases in body fluids and plasma throughout inflammation. Our study was designed to assess the diagnostic and prognostic value of cerebrospinal fluid (CSF) PTX3 levels in pediatric patients with different central nervous system (CNS) infections.

Objective: The Clarity AD phase III trial showed that lecanemab reduced amyloid markers in early Alzheimer's disease (AD) and resulted in less decline on measures of cognition and function than placebo. Herein, we aimed to characterize amyloid-β (Aβ) protofibril (PF) captured by lecanemab in human cerebrospinal fluid (CSF) from living participants with different stages in AD, which enable an enhanced understanding of the dynamic changes of lecanemab-associated Aβ-PF (Lec-PF) in vivo.

Methods: We newly developed a unique and highly sensitive immunoassay method using lecanemab that selectively captures Lec-PF.

Background: The treatment of refractory chronic rhinosinusitis with nasal polyps (CRSwNP) with omalizumab has been well studied based on clinical evaluation. Nevertheless, ideal quantitative or qualitative biomarkers for predicting a different response to biologics urgently need to be explored. We aim to identify potential biomarkers for predicting a good or poor response in patients with refractory CRSwNP.

Glioblastoma multiforme (GBM) is a highly malignant subtype of glioma, originating from the glial cells that provide support to other neurons in the brain. GBM predominantly impacts the cerebral hemisphere of the brain, with minimal effects on the cerebellum, brain stem, or spinal cord. Individuals diagnosed with GBM commonly encounter a range of symptoms, starting from auditory abnormalities to seizures.

Background: Certain peripheral proteins are believed to be involved in the development of Alzheimer's disease (AD), but the roles of other new protein biomarkers are still unclear. Current treatments aim to manage symptoms, but they are not effective in stopping the progression of the disease. New drug targets are needed to prevent Alzheimer's disease.
