Observational Study
The gradient between arterial and end-tidal carbon dioxide predicts in-hospital mortality in post-cardiac arrest patient.
We investigated the predictive value of the gradient between arterial carbon dioxide (PaCO2) and end-tidal carbon dioxide (ETCO2) (Pa-ETCO2) in post-cardiac arrest patients for in-hospital mortality. ⋯ The Pa-ETCO2 gap at 24 h after ROSC was associated with in-hospital mortality in post-cardiac arrest patients.

Review Meta Analysis
Serum cardiac troponins as prognostic markers in patients with traumatic and non-traumatic brain injuries: A meta-analysis.
The association between brain injury and elevated serum cardiac troponin (cTn) remains poorly understood. We conducted a systematic review and meta-analysis to evaluate whether elevated cTn increases the risk of mortality in patients with traumatic (TBI) or non-traumatic brain injury (NT-BI). ⋯ Pooled analysis indicates that elevated cTn is significantly associated with a high mortality in patients with TBI and NT-BI. Prospective clinical trials are needed to support these findings and to inform a biomarker risk stratification regardless of the mechanism of injury.
