Randomized Controlled Trial Comparative Study
Prospective, randomized, open-label phase II trial on concomitant intraventricular fibrinolysis and low-frequency rotation after severe subarachnoid hemorrhage.
The goal of this randomized, open-label phase II study was to investigate the effect of concomitant low-frequency head-motion therapy and intraventricular fibrinolysis in patients after surgical or endovascular treatment for aneurysmal subarachnoid hemorrhage. ⋯ http://www.controlled-trials.com.

Comparative Study
A case-controlled comparison of thrombolysis outcomes between wake-up and known time of onset ischemic stroke patients.
Wake-up ischemic stroke (WUIS) patients are not thrombolysed even if they meet other criteria for treatment. We hypothesized that patients with WUIS showing no or early ischemic changes on brain imaging will have thrombolysis outcomes comparable with those with known time of symptom onset. ⋯ Thrombolysis in selected patients with WUIS is feasible, and its outcomes are comparable with those thrombolysed with 0 to 4.5 hours.

A novel quantitative susceptibility mapping (QSM) processing technology has been developed to map tissue susceptibility property without blooming artifacts. We hypothesize that hematoma volume measurement on QSM is independent of imaging parameters, eliminating its echo time dependence on gradient echo MRI. ⋯ QSM can provide reliable measurement of hematoma volume, which can be performed rapidly and accurately using a semiautomated segmentation tool.

Comparative Study
Silent information regulator 1 protects the brain against cerebral ischemic damage.
Sirtuin 1 (SIRT1) is a member of NAD+-dependent protein deacetylases implicated in a wide range of cellular functions and has beneficial properties in pathologies including ischemia/reperfusion processes and neurodegeneration. However, no direct evidence has been reported on the direct implication of SIRT1 in ischemic stroke. The aim of this study was to establish the role of SIRT1 in stroke using an experimental model in mice. ⋯ These results support the idea that SIRT1 plays an important role in neuroprotection against brain ischemia by deacetylation and subsequent inhibition of p53-induced and nuclear factor κB-induced inflammatory and apoptotic pathways.

Comparative Study
Association of prestroke statin use and lipid levels with outcome of intracerebral hemorrhage.
It is unclear whether blood lipid profiles and statin use before intracerebral hemorrhage (ICH) are associated with its outcome. ⋯ Premorbid statin use did not affect the outcome of ICH, but lower low-density lipoprotein levels were associated with higher in-hospital mortality.
