Background And Purpose: Cognitive deficits are common in survivors of cardiac arrest (CA). The aim of this study was to examine the effect of therapeutic hypothermia after CA on cognitive functioning and neurophysiological outcome.
Methods: A cohort of 70 consecutive adult patients resuscitated from out-of-hospital ventricular fibrillation CA were randomly assigned to therapeutic hypothermia of 33 degrees C for 24 hours accomplished by external cooling or normothermia. Neuropsychological examination was performed to 45 of the 47 conscious survivors of CA (27 in hypothermia and 18 in normothermia group) 3 months after the incident. Quantitative electroencephalography (Q-EEG) and auditory P300 event-related potentials were studied on 42 patients at the same time point.
Results: There were no differences between the 2 treatment groups in demographic variables, depression, or delays related to the resuscitation. No differences were found in any of the cognitive functions between the 2 groups. 67% of patients in hypothermia and 44% patients in normothermia group were cognitively intact or had only very mild impairment. Severe cognitive deficits were found in 15% and 28% of patients, respectively. All Q-EEG parameters were better in the hypothermia-treated group, but the differences did not reach statistical significance. The amplitude of P300 potential was significantly higher in hypothermia-treated group.
Conclusions: The use of therapeutic hypothermia was not associated with cognitive decline or neurophysiological deficits after out-of-hospital CA.

We hypothesized that outborn neonates from smaller birth volume hospitals would have more frequent adverse short-term outcomes following therapeutic hypothermia (TH). Multicenter retrospective study comparing outcomes for small (<500 births/year), medium (501-1500 births/year), and large (>1500 births/year) hospitals in Northern New England. Multivariable logistic regression assessed the combined outcome of death/severe gray matter injury on MRI, controlling for encephalopathy severity and time to initiation of TH.

Background: Targeted temperature management (TTM) is considered a beneficial treatment for improving outcomes in patients with OHCA due to acute coronary syndrome (ACS). The comparative benefits of hypothermic TTM (32-34°C) versus normothermic TTM (35-36°C) are unclear. This study compares these TTM strategies in improving neurological outcomes and survival rates in OHCA patients with ACS.

Article Synopsis
- Hibernating animals can significantly lower their body temperature without damaging their organs, potentially due to active hypometabolism.
- Researchers studied the phosphorylation of Akt to see if metabolism decreases during artificial hypothermia in hamsters.
- They found that while hypothermia through adenosine A1 receptor activation decreased Akt phosphorylation significantly, anesthesia-induced hypothermia showed only partial reduction without organ damage, indicating both methods allow for regulated metabolic reduction.

Introduction: This study aimed to investigate the associations among seizures, clinical characteristics, and brain injury on Magnetic Resonance Imaging (MRI) in infants with Hypoxic Ischemic Encephalopathy (HIE), and to determine whether these findings can predict unfavorable neurodevelopmental outcomes.
Method: Clinical and electrographic seizures were assessed by amplitude-integrated electroencephalogram, and the extent of brain injury was evaluated by using MRI. At 12‒24 months of age, developmental impairment or death was assessed.

Purpose: Perinatal hypoxic-ischemic encephalopathy (HIE) is a significant cause of neonatal brain injury. Therapeutic hypothermia (TH) is the standard treatment for term neonates, but its safety and efficacy in neonates < 36 weeks gestational age (GA) remains unclear. This case series aimed to evaluate the outcomes of preterm infants with HIE treated with TH.
