Summary: This study aimed to investigate the prevalence of hypoxic-ischemic brain injury (HIBI) on head CT (HCT) obtained within two hours of return of spontaneous circulation (ROSC) in out-of-hospital cardiac arrest (OHCA) patients, and evaluate the association between early HIBI and neurologic outcome. The results showed that HIBI was present in 29% of HCTs obtained within 2 hours of ROSC and was strongly and inversely associated with survival with a good neurologic outcome.

Summary: This study aimed to investigate the predictors of death by neurological criteria (DNC) in patients resuscitated from out-of-hospital cardiac arrest (OHCA). The study found that initial brain imaging and electroencephalography (EEG) results can predict the prognosis of OHCA patients. The predictors included sulcal effacement, EEG background, and GWR.

Summary: The study showed that acute brain injury is the third leading cause of out of hospital cardiac arrest (OHCA), with patients often presenting with neurological prodromes such as seizures, headaches, and focal neurological signs. Patients with OHCA due to acute brain injury had a higher mortality compared to those due to other causes, but were more likely to be potential organ donors.

Summary: This retrospective study analyzed one hospital's TTM registry and found that approximately one-sixth of in-hospital death patients developed brain death after cardiac arrest. Comparing clinical variables and prognostic test results, the study identified that the gray-to-white matter ratio on early brain CT images and the S100B level at 72 hours may help to screen potential brain death.

Summary: This study investigated the association between shock severity, as defined by the SCAI Shock Classification, and in-hospital mortality and neurological outcome in comatose OHCA patients undergoing TTM. The study found that higher shock severity was associated with increased in-hospital mortality and a lower likelihood of good neurological outcome.

Summary: The study evaluated the role of serum S100 protein in early neuroprognostication of comatose survivors of out-of-hospital cardiac arrest. Results showed that increased S100 levels at 48 hours after the event were independently associated with unfavorable neurological outcomes at 30 days. A 48-hour S100 value >= 0.37 μg/L had high specificity (100%) and moderate sensitivity (39%) in predicting an unfavorable neurological outcome within 30 days.

Summary: Hypoxic ischaemic brain injury after resuscitation from cardiac arrest is associated with the response of the innate immune system, including pro-inflammatory cytokines, leucocyte migration and activation, and complement cascade. Inhibiting an immunopathological response may be an effective therapeutic strategy.

Summary: The aim of this study was to describe the characteristics of burn injury patients who were resuscitated after burn related out-of-hospital cardiac arrest (OHCA). The findings showed that patients with burn related OHCA have a poor prognosis, but patients who sustain electrical shock injuries may have a better outcome.

Summary: This study aimed to assess the effect of different blood pressure levels on global cerebral metabolism in comatose patients resuscitated from out-of-hospital cardiac arrest. The results showed that targeting a higher mean arterial blood pressure (MAP) did not significantly improve cerebral energy metabolism within 96 hours of post-resuscitation care. Patients with a poor clinical outcome exhibited significantly worse biochemical patterns, indicating that insufficient tissue oxygenation and recirculation during the initial hours after resuscitation were important factors determining neurological outcome.

Summary: This study found that compared to direct laryngoscopy, video laryngoscopy was associated with higher first pass success rate during endotracheal intubation in out-of-hospital cardiac arrest cases. However, video laryngoscopy was not associated with an increased rate of return of spontaneous circulation (ROSC), leaving its role in OHCA management unclear.

Summary: Activation of a volunteer responder system in cases of out-of-hospital cardiac arrest (OHCA) was associated with higher rates of bystander CPR, bystander defibrillation, and 30-day survival compared to no system activation. A randomized controlled trial is necessary to determine the causal effect of volunteer responder systems.

Summary: Reactive oxygen species (ROS) serve as signaling molecules that regulate physiological and pathophysiological processes by influencing the redox homeostasis and metabolic pathways within cells. Understanding the interactions between ROS signaling, metabolic adaptation, and redox balance is crucial for developing novel therapeutic strategies to treat various diseases in different tissues.

Summary: The study in England found that AEDs were disproportionately placed in areas with lower residential population density but higher workplace population density, predominantly white population, and higher socio-economically classified occupations. There was a significant correlation between AED coverage and the LSOA Index of Multiple Deprivation, with only 27.4% of AEDs located in the lowest IMD decile.

Summary: The GoodSAM mobile application, by alerting volunteer first-responders, can improve bystander cardiopulmonary resuscitation and defibrillation rates for out-of-hospital cardiac arrest patients, leading to increased survival rates. The study found that although the alert acceptance rates were low, they had a positive impact on patient survival to hospital discharge.

Summary: This study revealed that hyperglycaemia is a significant cause of QTc prolongation, and the additional effect of QTc-prolonging drugs like Moxifloxacin is additive. Gender differences may influence these effects. These findings highlight the heightened risk of QTc effects when prescribing medications to patients with Type 1 diabetes mellitus.

Summary: This study evaluated the impact of performing immediate coronary angiography (CAG) after out-of-hospital cardiac arrest (OHCA) with stratification of predicted neurologic injury and cardiogenic shock on arrival to a center. The results showed that immediate CAG was associated with improved survival with good neurologic outcome in low-risk patients with ST-segment elevation myocardial infarction and SCAI grade B to E shock.

Summary: A machine learning algorithm was developed to predict the presence of a culprit lesion in patients with out-of-hospital cardiac arrest. The algorithm incorporates nine variables and was validated using data from the King's Out-of-Hospital Cardiac Arrest Registry. The results showed that the algorithm has high accuracy in predicting culprit coronary artery disease lesions and outperforms the current standard electrocardiogram.

Summary: People who frequently call emergency ambulances perceive their care needs as urgent and ongoing. They are unable to see alternative ways to receive help and resolve problems. Communication between health professionals and service users appears inadequate. Further research is needed to understand service users' motivations and requirements to inform the design and delivery of accessible and effective services.

Summary: This study compared the discrimination performance of the MIRACLE2 score, downtime, and current randomized controlled trial (RCT) recruitment criteria in predicting poor neurologic outcome after out-of-hospital cardiac arrest (OHCA). The results showed that the MIRACLE2 score had a stronger association with outcome and higher discrimination for poor outcome compared to downtime and RCT recruitment criteria. The potential for the MIRACLE2 score to improve the selection of OHCA patients should be evaluated in future RCTs.
