Peripheral arterial disease (PAD) occurs when leg arteries become narrowed or blocked by plaque. These blockages can result in severe pain for patients, limited physical mobility, and life-threatening non-healing leg ulcers. According to the American Heart Association, this condition affects approximately 8 to 12 million Americans. With only about 25 percent of PAD patients undergoing treatment, it is a disease that is largely under-diagnosed and under-treated. If left untreated, PAD can lead to critical leg ischemia, a condition where not enough blood is being delivered to the leg to keep the tissue alive. Total loss of circulation to the legs and feet can cause gangrene and lead to amputation.
The first innovation is probably the world’s first multiple drug-eluting biodegradable stent for use in any part of the body where fluid flow, including blood, is disrupted.
Patterns in nature can be seen every day, yet in many cases, little is understood about how and why they form. Now University of Arizona mathematicians have found a way to predict natural patterns, including fingerprints and the spirals seen in cacti.
FDA today approved the use of oral fluid samples with a rapid HIV diagnostic test kit that provides screening results with over 99 percent accuracy in as little as 20 minutes. Until now, all rapid HIV tests required the use of blood in order to get such rapid results.
