Intravenous nicardipine infusion is effective for rapid blood pressure control. However, its use requires hemodynamic monitoring in the intensive care unit (ICU) and is associated with high hospital cost. This study aimed to examine the effect of early versus late initiation of oral antihypertensives on ICU length of stay (LOS) and cost of hospitalization in patients with hypertensive intracerebral hemorrhage (ICH). ⋯ Early initiation of oral antihypertensives is safe and may have a significant financial impact on patients with hypertensive ICH.

The hyperoxidative state in traumatic brain injury (TBI) could produce oxidative damage on the ribonucleic acid (RNA) and deoxyribonucleic acid (DNA). Oxidative damage to nucleic acids in TBI patients has been studied, and higher concentrations of 8-OHdG were found in postmortem brain samples of subjects who died following TBI than in subjects who died from sudden cardiac death. Thus, the objective of this study was to determine whether there is an association between serum DNA and RNA oxidative damage and mortality in TBI patients. ⋯ To our knowledge, our study is the largest series reporting data on DNA oxidative damage in TBI patients and is the first reporting DNA and RNA oxidative damage in TBI patients associating lipid peroxidation and mortality.

"Take a Number"-Precision Monitoring Directs Precision Therapy.

Clinical seizures following acute ischemic stroke (AIS) appear to contribute to worse neurologic outcomes. However, the effect of electrographic epileptiform abnormalities (EAs) more broadly is less clear. Here, we evaluate the impact of EAs, including electrographic seizures and periodic and rhythmic patterns, on outcomes in patients with AIS. ⋯ Electrographic seizures and periodic and rhythmic patterns in patients with AIS are associated with worse outcomes in a dose-dependent manner. Future studies are needed to assess whether treatment of this EEG activity can improve outcomes.

Comparative Study
Validation and Comparison of Noncontrast CT Scores to Predict Intracerebral Hemorrhage Expansion.
The BAT, BRAIN, and HEP scores have been proposed to predict hematoma expansion (HE) with noncontrast computed tomography (NCCT). We sought to validate these tools and compare their diagnostic performance. ⋯ The BAT, BRAIN, and HEP scores can predict HE with acceptable discrimination and require just a baseline NCCT scan. These tools may be used to stratify the risk of HE in clinical practice or randomized controlled trials.
