The diagnosis of nosocomial bacterial ventriculitis in patients with subarachnoid hemorrhage (SAH) can be challenging. ⋯ Nosocomial bacterial ventriculitis in patients with aneurysmal SAH is often suspected but confirmed by culture in a minority of cases. Improvement of diagnostics for nosocomial bacterial ventriculitis in patients with aneurysmal SAH is needed.

Inflammation and thrombosis are associated with the pathogenesis of aneurysmal subarachnoid hemorrhage (aSAH) and neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) are emerging as novel inflammatory markers in stroke. We aimed to identify the association of NLR and PLR with delayed cerebral ischemia (DCI) and 3-month outcome after aSAH. ⋯ NLR and PLR as novel inflammatory biomarkers are independent predictors of DCI development and functional outcome after acute aSAH. When combined together, they may help to identify high-risk patients more powerfully.

Electroencephalogram (EEG) background continuity is associated with a favorable prognosis in cardiac arrest patients post-therapeutic hypothermia. However, the continuous EEG in a subset of patients will undergo 'delayed EEG deterioration'; they will invariably have poor outcome. The aim of this study was to characterize this phenomenon. ⋯ Delayed EEG deterioration is associated with poor clinical outcomes. We hypothesize that this is the result of delayed neuronal degeneration, the exact mechanism requiring further exploration. Identifying patients with delayed EEG deterioration post-therapeutic hypothermia is paramount as further interventions may yet salvage their outcomes, though further study is needed.

Hyperglycemia in out-of-hospital cardiac arrest (OHCA) survivors is associated with poor outcomes. However, in the control of initial hyperglycemia, an adequate strategy to improve patients' neurologic outcomes remains undetermined. Prior to the establishment of such strategy, we need to determine whether a decreased rate of initial blood glucose (BG) affects patient outcomes. ⋯ Faster rates of initial BG decrease and the shorter time required to attain target BG levels were associated with favorable neurologic outcome in survivors of OHCA receiving therapeutic hypothermia.
