The accumulation of β-Amyloid (Αβ) and tau proteins in the brain is hallmark pathology for Alzheimer disease. Recently developed positron emission tomography (PET) tracers, including [18F]-AV-1451, bind to tau in neurofibrillary tangles in the brain. So, could tau imaging become a diagnostic marker for Alzheimer disease and provide insights into the pathophysiology of the neurodegenerative disorder that destroys brain cells?
Inpatient procedures are an integral part of routine stroke care. Some procedures, including intravenous thrombolysis (IVT) and carotid revascularization, have a curative intent to heal the patient, while others are life-sustaining procedures, including gastrostomy (feeding tube insertion), tracheostomy, mechanical ventilation and hemicraniectomy (to relieve pressure on the brain).
An engineer teamed up with a veterinarian to test a bone cancer drug delivery system in animals bigger than the standard animal model, the mouse. They chose dogs -- mammals closer in size and biology to humans -- with naturally occurring bone cancers, which also are a lot like human bone tumors. The researchers report their results in the Proceedings of the National Academy of Sciences.
Does a long travel time to a primary stroke center (PSC) offset the potential benefits of this specialized care?
Many medical students are using electronic health records (EHRs) to track former patients but the practice, which students report as being educational, raises some ethical questions, according to an article published online by JAMA Internal Medicine.
Inducing labor appears not to be associated with risk for autism spectrum disorders (ASDs) in offspring when siblings discordant for labor induction - induced vs. not induced births - were compared, according to an article published online by JAMA Pediatrics.
The legalization of recreational marijuana in Colorado was associated with both increased hospital visits and cases at a regional poison center because of unintentional exposure to the drug by children, suggesting effective preventive measures are needed as more states consider legalizing the drug, according to an article published online by JAMA Pediatrics.
Induction of labor appears not to be associated with increased risk of autism spectrum disorders in children in a large new study led by Harvard T.H. Chan School of Public Health. The new finding suggests that concern about autism risk should not factor into clinical decisions about whether or not to induce labor.
Unfortunately, loss of plant and animal habitat leads to local species extinctions and a loss of diversity from ecosystems. Fortunately, not all of the extinctions occur at once. Conservation actions may still be able to save threatened species, according to William Newmark, a vertebrate zoologist at the Natural History Museum of Utah at the University of Utah.
Honey bees are able to wiggle their abdomens in a variety of ways. Now new research published in the Journal of Insect Science shows how they are able to do it.
