Fundamental beliefs about atherosclerosis overturned
Jul 06, 2015
Doctors' efforts to battle the atherosclerotic plaques that cause heart attacks and strokes are built on several false beliefs about the fundamental composition and formation of the plaques, new research from the University of Virginia School of Medicine shows. These new discoveries will force researchers to reassess their approaches to developing treatments and discard some of their basic assumptions about atherosclerosis.

Mannitol dosing errors made during transport of patients with intracranial emergencies
Jun 15, 2015
Researchers in Alberta, Canada, investigated the use of the drug mannitol before and during transportation of patients with intracranial emergencies from peripheral hospitals to tertiary facilities that house neurosurgery departments. The focus was on the appropriate use of the drug and the extent to which dosing errors may have occurred. The authors found a 22% dosing error rate, with slightly more patients receiving a dose smaller, rather than larger, than the dose range recommended by the Brain Trauma Foundation.

Study identifies possible role for carbon monoxide in treating hemorrhagic stroke
May 26, 2015
A new study led by investigators at Beth Israel Deaconess Medical Center suggests that when administered in small, carefully controlled amounts, carbon monoxide may protect the brain from damage following subarachnoid hemorrhage. The new findings show that carbon monoxide can help accelerate a natural process that minimizes cognitive damage by speeding the clearance of heme.
Stroke risk clarified following routine thrombectomy
May 20, 2015
Clearing blood clots from arteries during treatment for an acute myocardial infarction was a relatively common practice until a recent, large-scale study showed that the technique, known as thrombectomy, might actually increase the risk of stroke. Now, new insights from the TOTAL trial, presented at EuroPCR 2015, indicate that the risk of stroke with thrombectomy during angioplasty, compared to angioplasty alone, is evident very early following the procedure.
