Glutamate release has been reported to be involved in the neuronal death following ischemic or anoxic injury. Riluzole (2-amino-6-trifluoromethoxy-benzothiazole) is a putative inhibitor of glutamate release. We investigated the effect of this drug on anoxic injury in vitro. Cerebellar granule cells grown in culture were exposed to an anoxic atmosphere for 16-20 h, Riluzole (100 microM) was found to prevent the degeneration of these neurons induced by anoxia.

Prognostic Value of Signal Abnormalities on Brain MRI in Post-Anoxic Super-Refractory Status Epilepticus: A Single-Center Retrospective Study.
Eur J Neurol
January 2025
Epilepsy Center, Department of Neurology, Fondazione IRCCS San Gerardo Dei Tintori, Monza, Italy.
Background: Epileptiform activity, including status epilepticus (SE), occurs in up to one-third of comatose survivors of cardiac arrest and may predict poor outcome. The relationship between SE and hypoxic-ischemic brain injury (HIBI) is not established.
Methods: This is a single-center retrospective study on consecutive patients with post-anoxic super-refractory SE.

To demonstrate the prevalence of malnutrition risk in a specific rehabilitation setting. The secondary aim of the study was to compare Malnutrition Screening Tool (MST) and Malnutrition Universal Screening Tool (MUST) with Nutritional Risk Screening-2002 (NRS-2002). Patients diagnosed with stroke, anoxic brain injury, spinal cord injury, multiple sclerosis, arthritis, neuromuscular diseases, Parkinson's disease, and lymphedema who were admitted to a rehabilitation hospital were included.

Although numerous definitions of brain death exist, the diagnosis and diagnostic process remain open to interpretation. We present the case of a 32-year-old male with systemic lupus erythematosus who presented to an outside hospital following a cardiac arrest while jogging. His electroencephalogram (EEG) showed abnormal contour in the posterior fields.

Background: Organ procurement from brain-dead pregnant women is rare and typically occurs postfetal delivery. In this case report, we describe organ procurement from a brain-dead woman in her third trimester of pregnancy with a nonviable fetus remaining in utero.
Case Summary: We report a 33-year-old woman at 38 weeks gestation who suffered anoxic brain injury following cardiac arrest due to suspected opioid overdose.
Association between hemolysis markers and neuron-specific enolase in AMICS patients supported with a microaxial flow pump.
Eur Heart J Acute Cardiovasc Care
January 2025
Department of Cardiology, Copenhagen University Hospital, Rigshospitalet, Copenhagen, Denmark.
Background: Acute myocardial infarction complicated by cardiogenic shock (AMICS) is frequently preceded by out-of-hospital cardiac arrest (OHCA), with risk of anoxic brain injury. Neuron-specific enolase (NSE) is central to neuroprognostication; however, concomitant hemolysis can increase NSE independent of neuronal injury due to the presence of NSE in erythrocytes. This consideration is critical in AMICS patients treated with a microaxial flow pump (Impella, Abiomed), where hemolysis is frequent.
