Neurocardiac risk stratification 6 hours after resuscitation from cardiac arrest

Introduction: • An increasing number of patients are resuscitated from out-ofhospital cardiac arrest. Triage to optimal treatment pathways could improve and increase the efficacy of post-resuscition care. • Despite great variability in etiology, duration, and patterns of injury from cardiac arrest, post-resuscitation treatment guidelines emphasize standard treatments. We hypothesize that by categorizing competing risks very early after resuscitation, it may be possible to improve the efficacy and efficiency of care. • When measured very early after resuscitation, suppression ratio (SR, the percentage of suppressed EEG), correlates with severity of brain injury and the likelihood of poor neurological outcome. • The CREST score2 is a validated model to predict circulatoryetiology death (CED) based on: Coronary artery disease, initial nonshockable Rhythm, Ejection fraction25 minutes

Cytotoxic polyfunctionality maturation of cytomegalovirus-pp65-specific CD4 + and CD8 + T-cell responses in older adults positively correlates with response size

Cytomegalovirus (CMV) infection is one of the most common persistent viral infections in humans worldwide and is epidemiologically associated with many adverse health consequences during aging. Previous studies yielded conflicting results regarding whether large, CMV-specific T-cell expansions maintain their function during human aging. In the current study, we examined the in vitro CMV-pp65-reactive T-cell response by comprehensively studying five effector functions (i.e., interleukin-2, tumor necrosis factor-α, interferon-γ, perforin, and CD107a expression) in 76 seropositive individuals aged 70 years or older. Two data-driven, polyfunctionality panels (IL-2-associated and cytotoxicity-associated) derived from effector function co-expression patterns were used to analyze the results. We found that, CMV-pp65-reactive CD8 + and CD4 + T cells contained similar polyfunctional subsets, and the level of polyfunctionality was related to the size of antigen-specific response. In both CD8 + and CD4 + cells, polyfunctional cells with high cytotoxic potential accounted for a larger proportion of the total response as the total response size increased. Notably, a higher serum CMV-IgG level was positively associated with a larger T-cell response size and a higher level of cytotoxic polyfunctionality. These findings indicate that CMV-pp65-specific CD4 + and CD8 + T cell undergo simultaneous cytotoxic polyfunctionality maturation during aging
