Article Abstract
Background: We measured postoperative changes in cerebrospinal fluid (CSF) interleukin (IL)-6 levels in subarachnoid hemorrhage (SAH) due to aneurysm rupture and examined factors associated with outcomes and cerebral vasospasm. We used physiologic saline or artificial CSF as the intraoperative irrigation fluid and examined the differences.
Methods: The participants were 16 men and 41 women who were transported to our facility for SAH and underwent surgical treatment during the period from February 2012 through March 2015. In terms of severity, 31 cases were World Federation of Neurological Surgeons (WFNS) grade I-III and 26 cases were grade IV-V. All cases underwent clipping. Physiologic saline and artificial CSF were used as intraoperative irrigation fluid. We placed a ventricular drainage tube intraoperatively and collected CSF daily from postoperative day (POD) 1 through 10 or until drain removal.
Results: IL-6 level varied from 74 pg/mL to 407,936 pg/mL and peaked on PODs 1 and 5. Patients with favorable outcomes had significantly lower postoperative IL-6 levels. POD 1 IL-6 level significantly differed in relation to the presence of cerebral vasospasm but was not associated with its timing or severity. Use of artificial CSF was associated with a significantly lower incidence of cerebral vasospasm. Age and WFNS grade were significantly associated with outcome, and use of artificial CSF had a tendency toward favorable outcomes.
Conclusions: Artificial CSF is a potentially useful intervention when managing subarachnoid hemorrhage.

A novel MRI-based deep learning-radiomics framework for evaluating cerebrospinal fluid signal in central nervous system infection.

Introduction: Accurate and timely diagnosis of central nervous system infections (CNSIs) is critical, yet current gold-standard techniques like lumbar puncture (LP) remain invasive and prone to delay. This study proposes a novel noninvasive framework integrating handcrafted radiomic features and deep learning (DL) to identify cerebrospinal fluid (CSF) alterations on magnetic resonance imaging (MRI) in patients with acute CNSI.
Methods: Fifty-two patients diagnosed with acute CNSI who underwent LP and brain MRI within 48 h of hospital admission were retrospectively analyzed alongside 52 control subjects with normal neurological findings.

The ratio between beta-amyloid (Aβ) peptides 40 and 42 is recognized as a biomarker for Alzheimer's disease, playing a significant role in early diagnosis and disease progression monitoring. Aβ peptides are present at trace levels in cerebrospinal fluid, therefore, developing a new selective extraction procedure is essential for isolating targeted biomarkers from the matrix interferents, ensuring accurate identification and quantification. In this study, a hybrid organic-silica monolith was synthesized in a 530 µm inner diameter-capillary and used for the covalent grafting of beta amyloid peptide aptamers.

: Glioblastoma multiforme (GBM) is the most common and aggressive primary brain tumour, associated with poor survival outcomes and significant clinical challenges. Conventional diagnostic methods, including MRI, CT, and histopathological analysis of tissue biopsies, are limited by their inability to reliably distinguish treatment effects from true tumour progression, often resulting in misdiagnosis and delayed intervention. Repeated tissue biopsies are also invasive and unsuitable for longitudinal monitoring.

The lateral suboccipital approach is a fundamental surgical method for accessing the cerebellopontine angle. This article outlines critical aspects, including anatomical landmarks, surgical positioning, and techniques for craniotomy and dural opening, based on practices at our institution. Important landmarks include the mastoid process, asterion, and suboccipital triangle, which contains critical structures such as the vertebral artery.

The increased occurrence and severity of cyber-attacks on critical infrastructure have underscored the need to embrace systematic and prospective approaches to resilience. The current research takes as its hypothesis that the InfraGuard Cybersecurity Framework-a capability model that measures the maturity of cyber resilience through three functional pillars, Cyber as a Shield, Cyber as a Space, and Cyber as a Sword-is an implementable and understandable means to proceed with. The model treats the significant aspects of situational awareness, active defense, risk management, and recovery from incidents and is measured using globally standardized maturity models like ISO/IEC 15504, NIST CSF, and COBIT.
