Review Meta Analysis
Antiplatelet therapy in aneurysmal subarachnoid hemorrhage: a systematic review.
Observational studies suggest that platelet inhibitors reduce the risk of delayed cerebral ischemia (DCI) after aneurysmal subarachnoid hemorrhage and thereby have a beneficial effect on clinical outcome. Robust evidence, however, is lacking. We performed a systematic meta-analysis to determine whether antiplatelet therapy has a beneficial effect after SAH. ⋯ Our data indicate that antiplatelet drugs reduce the risk of DCI in patients with subarachnoid hemorrhage. A randomized clinical trial is warranted to assess the effect on overall outcome.

Clinical Trial
Persistent poststroke hyperglycemia is independently associated with infarct expansion and worse clinical outcome.
Hyperglycemia at the time of ischemic stroke is associated with increased mortality and morbidity. Animal studies suggest that infarct expansion may be responsible. The influence of persisting hyperglycemia after stroke has not previously been examined. We measured the blood glucose profile after acute ischemic stroke and correlated it with infarct volume changes using T2- and diffusion-weighted MRI. ⋯ Persistent hyperglycemia on serial glucose monitoring is an independent determinant of infarct expansion and is associated with worse functional outcome. There is an urgent need to study normalization of blood glucose after stroke.

Hyperglycemia has a deleterious effect on brain ischemia. However, the effect of hyperglycemia in intracerebral hemorrhage (ICH) is not well known. We investigated the effect of hyperglycemia on the development of brain edema and perihematomal cell death in ICH. ⋯ Hyperglycemia caused more profound brain edema and perihematomal cell death in experimental ICH.
