Article Abstract
Objective: To determine whether leucine-rich alpha-2 glycoprotein 1 (LRG1) is a potential prognostic and severity biomarker in patients with aneurysmal subarachnoid hemorrhage (aSAH).
Methods: This observational and prospective study included 44 patients with aSAH from Nanjing Drum Tower Hospital from June to December 2020. Concentrations of LRG1 in the cerebrospinal fluid (CSF) were determined by enzyme-linked immunosorbent assay within 24 hours after aSAH. We further determined the relationship of CSF LRG1 levels with disease severity and prognosis 3 months after aSAH.
Results: Higher CSF LRG1 levels were associated with a higher Hunt-Hess grade (P < 0.05). Using univariate analysis, poor outcomes at 3 months were associated with higher World Federation of Neurological Surgeons scale grade, higher Hunt-Hess grade, higher CSF LRG1 levels, and higher Fisher grade. Logistic regression analysis revealed a significant impact of LRG1 on poor outcomes as well as after adjustment for confounding factors.
Conclusions: These findings suggest an increase in CSF LRG1 levels in patients with aSAH, which may serve as a potential biomarker of unfavorable prognosis and disease severity.

Alzheimer's disease and related dementias have a multifactorial aetiology and heterogeneous biology. The current study aims to identify different biological signatures in a deeply phenotyped memory clinic patient population. In this cross-sectional study, we analysed 49 pre-specified proteins using a multiplex antibody-based suspension bead array in 278 CSF samples from the real-world research database and biobank at the Karolinska University Hospital Memory Clinic, Solna, Sweden.

Article Synopsis
- The study investigates the inflammatory response of the central nervous system (CNS) to traumatic brain injury (TBI) using mass-spectrometry, comparing it to other CNS injuries and healthy controls.
- A total of 56 patients' cerebrospinal fluid (CSF) was analyzed, revealing significant differences in protein concentrations, with 55 proteins differing between TBI and noninfectious CNS disorders and 51 proteins differing between TBI and healthy controls.
- Notably, two proteins were uniquely identified in all TBI samples, and the study emphasizes the complexity of the inflammatory responses in various CNS conditions.

Background: Chronic hydrocephalus is a common complication of aneurysmal subarachnoid hemorrhage (aSAH); however, the risk factors and the mechanisms underlying its occurrence have yet to be fully elucidated. The purpose of this study was to identify biomarkers that could be used to predict chronic hydrocephalus after aSAH and to investigate the relationships.
Methods: We analyzed cerebrospinal fluid (CSF) samples from 19 patients with chronic hydrocephalus after aSAH and 44 controls without hydrocephalus after aSAH.

Background: After subarachnoid hemorrhage (SAH), early brain injury (EBI) and delayed cerebral ischemia (DCI) lead to poor outcomes. Discovery of biomarkers indicative of disease severity and predictive of DCI is important. We tested whether leucine-rich alpha-2-glycoprotein 1 (LRG1) is a marker of severity, DCI, and functional outcomes after SAH.
