Mechanism of cAMP Response Element-binding Protein 1/Death-associated Protein Kinase 1 Axis-mediated Hippocampal Neuron Apoptosis in Rat Brain Injury After Cardiopulmonary Resuscitation. Neuroscience 2023; 526:175-184. [PMID: 37406926 DOI: 10.1016/j.neuroscience.2023.06.024] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2023] [Revised: 06/25/2023] [Accepted: 06/27/2023] [Indexed: 07/07/2023]
Abstract
Brain injury represents a leading cause of deaths following cardiac arrest (CA) and cardiopulmonary resuscitation (CPR). This study explores the role of CREB1 (cAMP responsive element binding protein 1)/DAPK1 (death associated protein kinase 1) axis in brain injury after CPR. CA was induced by asphyxia in rats, followed by CPR. After CREB1 over-expression, the survival rate and neurological function score of rats were measured. Nissl and TUNEL staining evaluated the pathological condition of hippocampus and apoptosis of hippocampal neurons respectively. H19-7 cells were subjected to OGD/R and infected with oe-CREB1. CCK-8 assay and flow cytometry measured the cell viability and apoptosis. CREB1, DAPK1, and cleaved Caspase-3 expressions were examined using Western blot. The binding between CREB1 and DAPK1 was determined using ChIP and dual-luciferase reporter assays. CREB1 was poorly expressed while DAPK1 was highly expressed in rat hippocampus after CPR. CREB1 overexpression improved rat neurological function, repressed neuron apoptosis, and reduced cleaved Caspase-3 expression. CREB1 was enriched on the DAPK1 promoter and suppressed DAPK1 expression. DAPK1 overexpression reversed the inhibition of OGD/R-insulted apoptosis by CREB1 overexpression. To conclude, CREB1 suppresses hippocampal neuron apoptosis and mitigates brain injury after CPR by inhibiting DAPK1 expression.

Association between regional cerebral oxygen saturation and outcome of patients with out-of-hospital cardiac arrest: An observational study. Resusc Plus 2023; 13:100343. [PMID: 36686324 PMCID: PMC9852783 DOI: 10.1016/j.resplu.2022.100343] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2022] [Revised: 12/03/2022] [Accepted: 12/09/2022] [Indexed: 01/15/2023] Open
Abstract
Aim This study aimed to evaluate the association between cerebral oxygen saturation (StO2) and return of spontaneous circulation (ROSC) in patients with out-of-hospital cardiac arrest (OHCA). Methods We retrospectively evaluated the data of patients with OHCA to determine the association between ROSC and various StO2 parameters (initial_StO2, final_StO2, mean_StO2, and Δ_StO2 [=final_StO2-initial_StO2]). Time-domain near-infrared spectroscopy was used to determine absolute StO2 values. Results Of the 108 patients with OHCA, 23 achieved ROSC. Although initial_StO2 values did not differ between the groups, final_StO2, mean_StO2, and Δ_StO2 were higher in the ROSC group than in the non-ROSC group. The cut-off values for initial_StO2, mean_StO2, and Δ_StO2 as predictors of ROSC were 35%, 30%, and 5%, respectively. The odds ratio for ROSC had markedly increased in the Δ_StO2 ≥ 5% subgroup (19.70 [6.06-64.11], p < 0.001). When the change in StO2 (=d_StO2) at 8 min from the initiation of StO2 measurement was assessed, the d_StO2 ≥ 5% subgroup had a higher odds ratio for ROSC than the d_StO2 < 5% subgroup (5.8 [1.78-18.85], p = 0.002), and this tendency was maintained until 20 min. In the evaluation using a two-by-two contingency table with initial_StO2 and Δ_StO2 as two parameters, 61.9% of the patients fell under the categories of initial_StO2 < 35% and Δ_StO2 < 5% and had the lowest rate of ROSC achievement (4.6%). In the Δ_StO2 ≥ 5% subgroup, approximately-two-thirds of the patients achieved ROSC irrespective of the initial_StO2 (initial_StO2 ≥ 35%, 66.7%; initial_StO2 < 35%, 60.0%). Conclusions Initial_StO2 and Δ_StO2 were associated with the achievement of ROSC.

Abstract
Background Tissue oxygenation index (TOI) using the near infrared spectroscopy (NIRS) has been demonstrated as a useful indicator to predict return of spontaneous circulation (ROSC) among out-of-hospital cardiac arrest (OHCA) patients in hospital setting. However, it has not been widely examined based on pre-hospital setting. Methods In this prospective observational study, we measured TOI in pre-hospital setting among OHCA patients receiving cardio-pulmonary resuscitation (CPR) during ambulance transportation between 2017 and 2018. Throughout the pre-hospital CPR procedure, TOI was continuously measured. The study population was divided into two subgroups: ROSC group and non-ROSC group. Results Of the 81 patients included in the final analysis, 26 achieved ROSC and 55 did not achieve ROSC. Patients in the ROSC group were significantly younger, had higher ∆TOI (changes in TOI) (5.8 % vs. 1.3 %; p < 0.01), and were more likely to have shockable rhythms and event witnessed than patients in the non-ROSC group. ∆TOI cut-off value of 5 % had highest sensitivity (65.4 %) and specificity (89.3 %) for ROSC. Patients with a cut-off value ≤-2.0 % did not achieve ROSC and while all OHCA patient with a cut-off value ≥ 8.0 % achieved ROSC. In addition, ROSC group had stronger positive correlation between mean chest compression rate and ∆TOI (r = 0.82) than non-ROSC group (r = 0.50). Conclusions This study suggests that ∆ TOI could be a useful indicator to predict ROSC in a pre-hospital setting.

Abstract
BACKGROUND This study identified predictors of hospital mortality after successful weaning of patients with cardiogenic shock off venoarterial (VA) extracorporeal membrane oxygenation (ECMO) support.Methods and Results:Adult patients who received peripheral VA ECMO from January 2012 to April 2017 were reviewed retrospectively. After excluding patients who died on ECMO support, predictors for survival to discharge were investigated in patients who were successfully weaned off ECMO. Of 191 patients successfully weaned off ECMO, 143 (74.9%) survived to discharge. The prevalence of a history of stroke and coronary artery disease, as well as ECMO-related complications, including newly developed stroke and sepsis, was a higher in patients who did not survive to discharge than in those who did. On the day of ECMO weaning, Sequential Organ Failure Assessment score and serum lactate were higher in patients who did not survive to discharge, although there was no significant difference in blood pressure and the use of vasoactive drugs between the 2 groups. On multivariable analysis, stroke and sepsis during ECMO support, a lower Glasgow Coma Scale and acute kidney injury requiring continuous renal replacement therapy after weaning were significant predictors for in-hospital mortality. CONCLUSIONS Complications that occurred during ECMO and the presence of extracardiac organ dysfunction after weaning were associated with in-hospital mortality in patients with cardiogenic shock who were successfully weaned off ECMO.

Abstract
In intensive care medicine neuroprotection is understood mostly as various measures to avoid secondary brain damage after initial trauma, as in stroke, intracranial hemorrhage and resuscitation. Every brain trauma differs in the damage pattern and dynamics depending on the primary form of injury. Therefore, there are targeted treatment approaches depending on the pathophysiology of the medical condition. In addition, neuroprotective methods are desirable that are effective in the majority of patients with acute brain injury. In actual fact, in all forms of acute brain injury certain pathophysiological courses are encountered, which can lead to secondary brain damage depending on the intensity, e.g. reperfusion injury, damage to the blood-brain barrier and excitotoxicity. There is evidence to suggest that the creation of physiologically normal conditions leads to a favorable situation for the damaged brain. This article firstly describes the relevance of neuroprotective measures in neurocritical care medicine. Subsequently, general pathophysiological mechanisms in brain trauma are described. Following this, the pathophysiology and treatment options in brain pressure crises (reduction of intracranial pressure), anemia (transfusion management), hyperglycemia and hypoglycemia (adjustment of the blood sugar level) are dealt with. Finally, the use and benefits of therapeutic hypothermia are discussed. This has a special position as the only clinically effective individual measure for neuroprotection. The focus here is on the application following circulatory and cardiac arrest and resuscitation.

Abstract
The effects of cardiopulmonary resuscitation (CPR) on patients with advanced cancer remain to be elucidated. We identified a cohort of patients with stage-IV cancer who received in-hospital CPR from the Taiwan Cancer Registry and National Health Insurance claims database, along with a matched cohort without cancer who also received in-hospital CPR. The main outcomes were post-discharge survival and in-hospital mortality. In total, 3,446 stage-IV cancer patients who underwent in-hospital CPR after cancer diagnosis were identified during January 2009–June 2014. A vast majority of the patients did not survive to discharge (n = 2,854, 82.8%). The median post-discharge survival was 22 days; 10.1% (n = 60; 1.7% of all patients) of the hospital survivors received anticancer therapy after discharge. We created 1:1 age–, sex–, Charlson comorbidity index (CCI)–, and year of CPR–matched noncancer and stage-IV cancer cohorts (n = 3,425 in both; in-hospital mortality rate = 82.1% and 82.8%, respectively). Regression analysis showed that the stage-IV cancer cohort had shorter post-discharge survival than did the noncancer cohort. The outcome of patients with advanced cancer was poor. Even among the survivors, post-discharge survival was short, with only few patients receiving further anticancer therapy.

Abstract
BACKGROUND Neurological injuries remain the leading cause of death in comatose patients resuscitated from out-of-hospital cardiac arrest (OHCA). Adequate blood pressure is of paramount importance to optimize cerebral perfusion and to minimize secondary brain injury. Markers measuring global cerebral ischemia caused by cardiac arrest and consecutive resuscitation and reflecting the metabolic variations after successful resuscitation are needed to assist a more individualized post-resuscitation care. Currently, no technique is available for bedside evaluation of global cerebral energy state, and until now blood pressure targets have been based on limited clinical evidence. Recent experimental and clinical studies indicate that it might be possible to evaluate cerebral oxidative metabolism from measuring the lactate-to-pyruvate (LP) ratio of the draining venous blood. In this study, jugular bulb microdialysis and immediate bedside biochemical analysis are introduced as new diagnostic tools to evaluate the effect of higher mean arterial blood pressure on global cerebral metabolism and the degree of cellular damage after OHCA. METHODS/DESIGN This is a single-center, randomized, double-blinded, superiority trial. Sixty unconscious patients with sustained return of spontaneous circulation after OHCA will be randomly assigned in a one-to-one fashion to low (63 mm Hg) or high (77 mm Hg) mean arterial blood pressure target. The primary end-point will be a difference in mean LP ratio within 48 h between blood pressure groups. Secondary end-points are (1) association between LP ratio and all-cause intensive care unit (ICU) mortality and (2) association between LP ratio and survival to hospital discharge with poor neurological function. DISCUSSION Markers measuring cerebral ischemia caused by cardiac arrest and consecutive resuscitation and reflecting the metabolic changes after successful resuscitation are urgently needed to enable a more personalized post-resuscitation care and prognostication. Jugular bulb microdialysis may provide a reliable global estimate of cerebral metabolic state and can be implemented as an entirely new and less invasive diagnostic tool for ICU patients after OHCA and has implications for early prognosis and treatment.

Abstract
The burden of neurologic disease in the United States continues to increase due to a growing older population, increased life expectancy, and improved mortality after cancer and cardiac disease. Emergency medical services (EMS) providers are responding to more patients with stroke, traumatic neurologic injury, neuromuscular weakness, seizure, and spontaneous cardiac arrest. Efficient prehospital care and triage to facilities with specialized services improve outcomes. Effective handoff from EMS to an emergency department ensures continuity of care and patient safety. Although advancements in prehospital cardiopulmonary resuscitation have increased rates of return to spontaneous circulation, a large proportion of patients sustain neurologic injury.

Abstract
BACKGROUND The neurological prognosis of patients after cardiopulmonary resuscitation (CPR) is difficult to assess. GFAP is an astrocytic intermediate filament protein released into bloodstream in case of cell death. We performed a prospective study aiming to compare the predictive potential of GFAP after resuscitation to the more widely used biomarker neuron-specific enolase (NSE). METHODS One hundred patients were included at 48 h (tolerance interval ±12 h) after cardiac arrest. A serum sample was collected immediately after study inclusion. We determined serum levels of GFAP and NSE by means of immunoassays. Primary outcome was the modified Glasgow outcome scale at 4 weeks. Values below four were considered as a poor functional outcome. RESULTS Median GFAP levels in poor outcome (n = 61) and good outcome (n = 39) patients were 0.03 μg/L (interquartile range 0.01-0.07 μg/L) and 0.02 μg/L (0.01-0.03 μg/L; p = 0.014), respectively. GFAP revealed a sensitivity of 60.7% and a specificity of 66.7% to predict a poor functional outcome. All patients having a GFAP level >0.08 µg/L had a poor functional outcome. For NSE, sensitivity was 44.3% and specificity was 100.0% for predicting a poor outcome. Multivariate regression analysis revealed GFAP, NSE, and the Karnofsky index to be independent predictors of outcome. CONCLUSIONS The release patterns of GFAP and NSE after CPR show differences. GFAP levels above 0.08 µg/L were associated with a poor outcome in all cases, and patients with strongly elevated values (>3 µg/L) consistently had severe brain damage on brain imaging. Both biomarkers independently contribute to outcome prediction after CPR.

Abstract
BACKGROUND Survivors of cardiac arrest often experience neurologic deficits. To date, treatment options are limited. Associated hyperglycemia is believed to further worsen the neurologic outcome. The aim with this study was to characterize expression pathways induced by hyperglycemia in conjunction with global brain ischemia. METHODS Pigs were randomized to high or normal glucose levels, as regulated by glucose and insulin infusions with target levels of 8.5-10 mM and 4-5.5 mM, respectively. The animals were subjected to 5-minute cardiac arrest followed by 8 minutes of cardiopulmonary resuscitation and direct-current shock to restore spontaneous circulation. Global expression profiling of the cortex using microarrays was performed in both groups. RESULTS A total of 102 genes differed in expression at P < .001 between the hyperglycemic and the normoglycemic pigs. Several of the most strongly differentially regulated genes were involved in transport and metabolism of glucose. Functional clustering using bioinformatics tools revealed enrichment of multiple biological processes, including membrane processes, ion transport, and glycoproteins. CONCLUSIONS Hyperglycemia during cardiac arrest leads to differential early gene expression compared with normoglycemia. The functional relevance of these expressional changes cannot be deduced from the current study; however, the identified candidates have been linked to neuroprotective mechanisms and constitute interesting targets for further studies.

Abstract
OBJECTIVE We sought to provide evidence-based guidelines regarding the diagnosis and management of amniotic fluid embolism. STUDY DESIGN A systematic literature review was performed using MEDLINE, PubMed, EMBASE, and the Cochrane Library. The search was restricted to English-language articles published from 1966 through March 2015. Priority was given to articles reporting original research, in particular randomized controlled trials, although review articles and commentaries were consulted. Abstracts of research presented at symposia and scientific conferences were not considered adequate for inclusion. Evidence reports and published guidelines were also reviewed, and additional studies were located by reviewing bibliographies of identified articles. Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology was used for defining the strength of recommendations and rating quality of the evidence. Consistent with US Preventive Task Force guidelines, references were evaluated for quality based on the highest level of evidence. RESULTS AND RECOMMENDATIONS We recommend the following: (1) we recommend consideration of amniotic fluid embolism in the differential diagnosis of sudden cardiorespiratory collapse in the laboring or recently delivered woman (GRADE 1C); (2) we do not recommend the use of any specific diagnostic laboratory test to either confirm or refute the diagnosis of amniotic fluid embolism; at the present time, amniotic fluid embolism remains a clinical diagnosis (GRADE 1C); (3) we recommend the provision of immediate high-quality cardiopulmonary resuscitation with standard basic cardiac life support and advanced cardiac life support protocols in patients who develop cardiac arrest associated with amniotic fluid embolism (GRADE 1C); (4) we recommend that a multidisciplinary team including anesthesia, respiratory therapy, critical care, and maternal-fetal medicine should be involved in the ongoing care of women with AFE (Best Practice); (5) following cardiac arrest with amniotic fluid embolism, we recommend immediate delivery in the presence of a fetus ≥23 weeks of gestation (GRADE 2C); (6) we recommend the provision of adequate oxygenation and ventilation and, when indicated by hemodynamic status, the use of vasopressors and inotropic agents in the initial management of amniotic fluid embolism. Excessive fluid administration should be avoided (GRADE 1C); and (7) because coagulopathy may follow cardiovascular collapse with amniotic fluid embolism, we recommend the early assessment of clotting status and early aggressive management of clinical bleeding with standard massive transfusion protocols (GRADE 1C).

Abstract
Neuroprotective strategies that limit secondary tissue loss and/or improve functional outcomes have been identified in multiple animal models of ischemic, hemorrhagic, traumatic and nontraumatic cerebral lesions. However, use of these potential interventions in human randomized controlled studies has generally given disappointing results. In this paper, we summarize the current status in terms of neuroprotective strategies, both in the immediate and later stages of acute brain injury in adults. We also review potential new strategies and highlight areas for future research.
