Race/Ethnic Differences in the Risk of Hemorrhagic Complications Among Patients With Ischemic Stroke Receiving Thrombolytic Therapy Clinical Sciences
Conclusions— In patients with stroke receiving tPA, hemorrhagic complications were slightly higher in blacks and Asians, but not in Hispanics compared with whites. Asians also faced significantly higher risk for sICH relative to other race/ethnic groups. Future studies are needed to evaluate whether reduction in tPA dose similar to that used in many Asian countries could improve the safety of tPA therapy in Asians in the United States with acute ischemic strokes while maintaining efficacy.

Reducing haemorrhagic transformation after thrombolysis for stroke: a strategy utilising minocycline.
Authors: Blacker DJ, Prentice D, Alvaro A, Bates TR, Bynevelt M, Kelly A, Kho LK, Kohler E, Hankey GJ, Thompson A, Major T Abstract Haemorrhagic transformation (HT) of recently ischaemic brain is a feared complication of thrombolytic therapy that may be caused or compounded by ischaemia-induced activation of matrix metalloproteinases (MMPs). The tetracycline antibiotic minocycline inhibits matrix MMPs and reduces macroscopic HT in rodents with stroke treated with tissue plasminogen activator (tPA). The West Australian Intravenous Minocycline and TPA Stroke Study (WAIMATSS) aims to determine the safety and efficacy ...

Role of Imaging in Current Acute Ischemic Stroke Workflow for Endovascular Therapy Understanding and Applying the Endovascular Trials
Ischemic stroke is caused by a thrombus that blocks an intracranial artery. Brain tissue beyond the blocked artery survives for a variable period of time because of blood and nutrients received through tiny vessels called collaterals. Imaging the brain and the vasculature that supplies it is therefore a vital first step in treating patients with acute ischemic stroke. In this review, we focus on current evidence for imaging selection of patients for endovascular therapy in the context of the recently positive clinical trials, such as Multicenter Randomized Clinical Trial of Endovascular Treatment for Acute Ischemic Stroke ...

Younger Stroke Patients With Large Pretreatment Diffusion-Weighted Imaging Lesions May Benefit From Endovascular Treatment Clinical Sciences
Conclusions— There was a growing risk for poor outcome and symptomatic intracerebral hemorrhage with increasing pretreatment DWI lesion volumes. Nevertheless, favorable outcome was achieved in every third patient with DWI lesions >70 mL after successful endovascular reperfusion, whereas after poor or failed reperfusion, outcome was favorable in only every 12th patient. Therefore, endovascular treatment might be considered in patients with large DWI lesions, especially in younger patients.

Effects of Blood Pressure and Blood Pressure-Lowering Treatment During the First 24 Hours Among Patients in the Third International Stroke Trial of Thrombolytic Treatment for Acute Ischemic Stroke Clinical Sciences
Conclusions— Among patients with ischemic stroke who are candidates for thrombolytic treatment, high baseline blood pressure and a large pressure variability during the first 24 hours may be associated with a poor prognosis, whereas a large reduction in blood pressure and the use of blood pressure–lowering treatment during the first 24 hours may be associated with a favorable prognosis. These data support the rationale for further trials of agents that lower blood pressure or reduce blood pressure variability in the acute phase of ischemic stroke.

Long-term survival and serial assessment of stroke damage and recovery - practical and methodological considerations.
Authors: Modo M Abstract Impairments caused by stroke remain the main cause for adult disability. Despite a vigorous research effort, only 1 thrombolytic treatment has been approved in acute stroke (<3h). The limitations of preclinical studies and how these can be overcome have been the subject of various guidelines. However, often these guidelines focus on the acute stroke setting and omit long-term outcome measures, such as behaviour and neuroimaging. The considerations and practicalities of including the serial assessment of these approaches and their significance to establish therapeutic efficacy are discuss...

Intravenous Thrombolysis With Recombinant Tissue-Type Plasminogen Activator in a Stroke Patient Receiving Dabigatran Anticoagulant After Antagonization With Idarucizumab Brief Reports
Conclusions— This case represents a new therapeutic paradigm. It is further supported by in vitro data showing no nonspecific interactions of idarucizumab with recombinant tissue-type plasminogen activator–induced thrombolysis. Thus, patients effectively anticoagulated with dabigatran who were previously contraindicated for thrombolytic therapy in this situation may now receive treatment because of the ability to rapidly reverse the anticoagulant activity of dabigatran with idarucizumab.

Coexistent Sickle Cell Disease Has No Impact on the Safety or Outcome of Lytic Therapy in Acute Ischemic Stroke Clinical Sciences
Conclusions—Coexistent SCD had no significant impact on the safety or outcome of thrombolytic therapy in acute ischemic stroke. Although the sample size is relatively small, these data suggest that adults with SCD and acute ischemic stroke should be treated with thrombolysis, if they otherwise qualify. Addition studies, however, should track the intracranial hemorrhage rate and provide information on other SCD-related care such as transfusion.

Nongated Cardiac Computed Tomographic Angiograms for Detection of Embolic Sources in Acute Ischemic Stroke Clinical Sciences
Conclusions—Including the heart and ascending aorta in a routine non–ECG-gated computed tomographic angiogram enhances an existing imaging modality, with no increased incidence of contrast-induced nephropathy and minimal increase in radiation dose. This may help in the detection of high-risk cardiac and aortic sources of embolism in acute stroke patients.
