Efforts to improve hospital care

Two studies using standardized measures found that hospitals improved on 15 of 18 clinical performance measures, but didn't show significant reductions in early deaths from heart attacks and injuries during delivery. The findings suggest that higher levels of adherence with evidence-based guidelines are achievable, but may be somewhat ...

Pinpointing a culprit molecule in Alzheimer's disease

Researchers created transgenic mice overproducing Ab40 and Ab42 to study their roles in AD pathology. The results showed that Ab42 mice accumulated extensive amyloid plaque and neural damage, while Ab40 mice showed little disease pathology. The study provides evidence for the critical role of Ab42 in initiating amyloid deposition.
