Animal models enabling reliable access to ventricular cerebrospinal fluid (CSF) are crucial to the study of neuropharmacological and neurotoxicological effects of cytotoxic agents used to treat central nervous system neoplasms. This investigation concludes that 4th ventricular catheterization using subcutaneous CSF reservoirs in rhesus monkeys: (a) provides chronic access to sterile CSF without chronic immobilization, (b) enables mixing of injected drugs with lateral ventricular CSF, (c) permits sensitive monitoring of intraventricular pressure and (d) does not produce tissue damage during cannula implantation or breakdown of the blood-brain barrier.

Gliomas are the most common brain tumor type in children and adolescents. To date, diagnosis and therapy monitoring for these tumors rely on magnetic resonance imaging (MRI) and histopathological as well as molecular analyses of tumor tissue. Recently, liquid biopsies (LB) have emerged as promising tool for diagnosis and longitudinal tumor assessment potentially allowing for a more precise therapeutic management.

Background: Knowledge of the chemical composition of amyloid plaques and tau tangles at the earlier stages of Alzheimer's disease (AD) pathology is sparse. This is due to limited access to human brain during life and at the earlier stages of AD pathophysiology and technical limitations in quantifying amyloid and tau species at a subcellular level. Understanding the chemical composition of plaques and tangles, how rapidly they grow and what factors drive growth is important for developing and refining therapeutics.

Background: Preclinical Alzheimer's disease may be linked to impaired cerebral amyloid clearance. We aim to obtain dynamic parameters of cortical and ventricular clearance of C-PIB and compare them with CSF amyloid values in a population of healthy volunteers.
Method: We evaluated 8 healthy volunteers (4 men and mean age: 64.
Reducing Cerebrospinal Fluid Sampling Frequency and Costs in Patients With Ventriculostomy for Aneurysmal Subarachnoid Hemorrhage: A Quality Improvement Initiative.

Background: We implemented a quality improvement project to transition from routine cerebrospinal fluid (CSF) sampling to indication-based sampling in aneurysmal subarachnoid hemorrhage (aSAH) patients with an external ventricular drain (EVD).
Methods: Forty-seven patients were assessed across 2 epochs: routine (n=22) and indication-based (n=25) CSF sampling. The primary outcome was the number of CSF samples, and secondary outcomes included cost reductions and ventriculostomy-associated infections.
Impact of lumbar cerebrospinal fluid drainage to control intracranial hypertension in patients with severe traumatic brain injury: a retrospective monocentric cohort.

Trauma Critical Care Unit, Montpellier University Hospital, 34295 Cedex 5, Montpellier, France.
Background: External lumbar drainage (ELD) of cerebrospinal fluid may help control intracranial pressure following a traumatic brain injury. We aimed to assess the efficacy and safety of ELD in post-traumatic intracranial hypertension (IH).
Methods: This retrospective monocentric cohort study was conducted in the trauma critical care unit of the regional Level-I trauma centre between January 2012 and December 2022.
