Article Synopsis
  • The study explored the effect of perampanel, an AMPA receptor antagonist, on reducing hyperexcitability around gliomas, which could promote tumor growth.
  • An open-label trial compared perampanel with standard care in patients with high-grade glioma undergoing surgery, measuring outcomes like high-frequency oscillation rates and seizure occurrence.
  • Results showed no significant difference in hyperexcitability outcomes between perampanel and standard care, and early termination of the trial indicated similar seizure rates and overall survival for both treatments.

Article Synopsis
  • The Swiss guidelines for driving with epilepsy require EEG findings to be compatible with fitness to drive (FTD), but they lack specific criteria, prompting a nationwide survey to assess how neurologists apply this in practice.
  • In the survey, 102 neurologists reported variances in their assessment of EEG results, notably regarding normal variants and certain pathological patterns, revealing significant disagreement on evaluating FTD.
  • The findings highlight the need for more standardized criteria and additional research, as many participants supported the inclusion of EEG results in FTD assessments but noted that follow-up tests like reaction-time evaluations were infrequently conducted.

Background: Although magnetic resonance imaging, particularly diffusion-weighted imaging, has increasingly been used as part of a multimodal approach to prognostication in patients who are comatose after cardiac arrest, the performance of quantitative analysis of apparent diffusion coefficient (ADC) maps, as compared to standard radiologist impression, has not been well characterized. This retrospective study evaluated quantitative ADC analysis to the identification of anoxic brain injury by diffusion abnormalities on standard clinical magnetic resonance imaging reports.

Methods: The cohort included 204 previously described comatose patients after cardiac arrest.

Article Synopsis
  • Iridium(III) organometallic complexes play a crucial role in the development of organic light-emitting diodes (OLEDs), but the link between their structure and light-emitting efficiency is not fully understood.*
  • Experimental and theoretical studies reveal that two similar iridium complexes, Red-pq and Red-piq, have different properties due to variations in the arrangement of their ligands, which affects their excited state geometry and quantum efficiency.*
  • The study finds that the greater geometric distortion in the Red-piq complex leads to reduced nonradiative decay, resulting in a higher quantum yield compared to Red-pq, thus highlighting how minor structural differences can impact performance in OLED applications.*

Article Synopsis
  • * A significant increase in the use of second-line immunotherapies (like anakinra) and the ketogenic diet was observed from 2022 to 2023, with 69% of patients receiving second-line immunotherapy compared to 40% before 2022.
  • * Early administration of certain therapies, particularly anakinra and tocilizumab, was linked to shorter durations of status epilepticus, suggesting a potential avenue for future research on treatment timing and patient outcomes.

Article Synopsis
  • The study investigated the effects of the AMPA receptor antagonist perampanel on hyperexcitability and clinical outcomes in patients undergoing surgery for high-grade glioma.
  • The trial compared perampanel to standard care using levetiracetam, measuring intraoperative hyperexcitability through high-frequency oscillation (HFO) rates and tracking seizure-free outcomes and overall survival.
  • Results indicated no significant difference in hyperexcitability or survival outcomes between the two treatments, leading to the early termination of the trial due to futility, while perampanel was found to be safe and well-tolerated.

Febrile infection-related epilepsy syndrome (FIRES) is a subset of new onset refractory status epilepticus (NORSE) that involves a febrile infection prior to the onset of the refractory status epilepticus. It is unclear whether FIRES and non-FIRES NORSE are distinct conditions. Here, we compare 34 patients with FIRES to 30 patients with non-FIRES NORSE for demographics, clinical features, neuroimaging, and outcomes.

The excited-state proton transfer (ESPT) reaction is an important primary photochemical process because it is closely related to photophysical properties. Although ESPT research in aqueous solutions is predominant, alcoholic solvent-mediated ESPT studies are also significant in terms of photoacid-based reactions. Especially, the research for dihydroxynaphthalenes (DHNs) has been largely neglected due to the challenging data interpretation of two hydroxyl groups.

Background: Distinct genetic alterations determine glioma aggressiveness, however, the diversity of somatic mutations contributing to peritumoral hyperexcitability and seizures over the course of the disease is uncertain. This study aimed to identify tumor somatic mutation profiles associated with clinically significant hyperexcitability.

Methods: A single center cohort of adults with WHO grades 1-4 glioma and targeted exome sequencing (n = 1716) was analyzed and cross-referenced with a validated EEG database to identify the subset of individuals who underwent continuous EEG monitoring (n = 206).

Cenobamate is an effective new adjunctive antiseizure medication (ASM) for treatment resistant focal epilepsy. It has broad spectrum anticonvulsant activity and may be a useful medication for super refractory status epilepticus (SRSE), but has not yet been studied in generalized seizures or an inpatient setting. Here we describe 2 SRSE cases where cenobamate was added safely to other treatments.

Background And Objectives: Seizures (SZs) and other SZ-like patterns of brain activity can harm the brain and contribute to in-hospital death, particularly when prolonged. However, experts qualified to interpret EEG data are scarce. Prior attempts to automate this task have been limited by small or inadequately labeled samples and have not convincingly demonstrated generalizable expert-level performance.

Distinct genetic alterations determine glioma aggressiveness, however the diversity of somatic mutations contributing to peritumoral hyperexcitability and seizures is uncertain. In a large cohort of patients with sequenced gliomas (n=1716), we used discriminant analysis models to identify somatic mutation variants associated with electrographic hyperexcitability in a subset with continuous EEG recording (n=206). Overall tumor mutational burdens were similar between patients with and without hyperexcitability.

Background And Objectives: The validity of brain monitoring using electroencephalography (EEG), particularly to guide care in patients with acute or critical illness, requires that experts can reliably identify seizures and other potentially harmful rhythmic and periodic brain activity, collectively referred to as "ictal-interictal-injury continuum" (IIIC). Previous interrater reliability (IRR) studies are limited by small samples and selection bias. This study was conducted to assess the reliability of experts in identifying IIIC.

Background: Immune effector cell-associated neurotoxicity syndrome (ICANS) is a clinical and neuropsychiatric syndrome that can occur days to weeks following administration chimeric antigen receptor (CAR) T-cell therapy. Manifestations of ICANS range from encephalopathy and aphasia to cerebral edema and death. Because the onset and time course of ICANS is currently unpredictable, prolonged hospitalization for close monitoring following CAR T-cell infusion is a frequent standard of care.

CAR-T cell therapy is an effective cancer therapy for multiple refractory/relapsed hematologic malignancies but is associated with substantial toxicity, including Immune Effector Cell Associated Neurotoxicity Syndrome (ICANS). Improved detection and assessment of ICANS could improve management and allow greater utilization of CAR-T cell therapy, however, an objective, specific biomarker has not been identified. We hypothesized that the severity of ICANS can be quantified based on patterns of abnormal brain activity seen in electroencephalography (EEG) signals.
