Stroke News and Research

RSS

A stroke is a medical emergency. Strokes happen when blood flow to your brain stops. Within minutes, brain cells begin to die. There are two kinds of stroke. The more common kind, called ischemic stroke, is caused by a blood clot that blocks or plugs a blood vessel in the brain. The other kind, called hemorrhagic stroke, is caused by a blood vessel that breaks and bleeds into the brain. "Mini-strokes" or transient ischemic attacks (TIAs), occur when the blood supply to the brain is briefly interrupted.

PKM-zeta-less adult mice still able to form long-term memories

A study by Johns Hopkins researchers has shown that a widely accepted model of long-term memory formation - that it hinges on a single enzyme in the brain - is flawed. The new study, published in the Jan. 2 issue of Nature, found that mice lacking the enzyme that purportedly builds memory were in fact still able to form long-term memories as well as normal mice could.

The Joint Commission, AHA/ASA recognize HUP with Comprehensive Stroke Center Certification

The Hospital of the University of Pennsylvania (HUP) has been recognized by The Joint Commission and the American Heart Association/American Stroke Association (AHA/ASA) as meeting The Joint Commission's standards for Disease-Specific Care Comprehensive Stroke Center Certification, becoming the first center in Philadelphia and among a select few hospitals in the United States to be named as part of an elite group of providers focused on complex stroke care.

Itch-specific nerve cells in skin discovered by John Hopkins scientists

Johns Hopkins researchers have uncovered strong evidence that mice have a specific set of nerve cells that signal itch but not pain, a finding that may settle a decades-long debate about these sensations, and, if confirmed in humans, help in developing treatments for chronic itch, including itch caused by life-saving medications.

No significant difference in patient outcomes with RBC transfusions using lower threshold levels

The level at which red blood cells are transfused, a common treatment in clinical practice, is often deliberated among physicians. Guidelines for blood transfusion levels were only recently issued in March 2012 diminishing some of the debate. Today, in a new section called JAMA Clinical Evidence Synopsis, the Journal of the American Medical Association (JAMA), published a summary of the systematic review of the 19 clinical trials that compare higher versus lower hemoglobin thresholds in red blood cell transfusion.

TFP5 molecule restores memory in mice with Alzheimer's

A new ray of hope has broken through the clouded outcomes associated with Alzheimer's disease. A new research report published in January 2013 print issue of the FASEB Journal by scientists from the National Institutes of Health shows that when a molecule called TFP5 is injected into mice with disease that is the equivalent of human Alzheimer's, symptoms are reversed and memory is restored-without obvious toxic side effects.

Stent placement ‘effective alternative to IVT in stroke patients’

In stroke patients in whom intravenous thrombolysis is either contraindicated or has failed, intra-arterial revascularization with cerebral angioplasty and stent placement is an effective and well-tolerated treatment, say Czech researchers.

Oral Eliquis receives FDA approval for treatment of clots in non-valvular atrial fibrillation patients

The U.S. Food and Drug Administration today approved the anti-clotting drug Eliquis (apixaban), an oral tablet used to reduce the risk of stroke and dangerous blood clots (systemic embolism) in patients with atrial fibrillation that is not caused by a heart valve problem.

Antibiotics do not help lower-respiratory tract infections

The antibiotic amoxicillin fares no better at reducing symptoms in patients with lower-respiratory tract infections than a placebo drug, indicate data from a dozen European countries.

Uncharacterized TLR plays key role in Toxoplasma gondii response

A previously uncharacterized toll-like receptor appears to play a crucial role in the innate immune response to Toxoplasma gondii infection and may promote host resistance, potentially leading to anti-parasite vaccines, say US researchers.
