Researchers at Oregon State University have demonstrated that nanofiber dressings that enhance innate immune responses may be gamechangers in fighting surgical site infections and promoting wound healing. Their findings, published in Nanomedicine, indicate that nanofiber wound dresses containing vitamin D offer significant advantages, including nonscarring wound healing and a reduced likelihood of contributing to drug resistance.

Breakthrough in Wound Healing
Nanofiber-based wound dressings loaded with vitamin D spur the production of an antimicrobial peptide, a key step forward in the battle against surgical site infections.
The findings by Oregon State University (OSU) researchers and other collaborators, published in Nanomedicine, are important because surgical site infections are the most common health care-associated infection and result in widespread human suffering and economic loss.
Each year in the United States alone, nearly 300,000 surgical patients develop an infection within 30 days of their operation—accounting for an estimated $10 billion in additional health care costs—and more than 13,000 of those people die.
Researchers used electrospinning to prepare dressings containing the bioactive form of vitamin D: 1,25-dihydroxyvitamin D3, or 1,25(OH)2D3.

Detecting Wheat/Gluten Reactivity
Cyrex Laboratories has released a new test panel, Array 3X, for microbial transglutaminase, gliadin toxic peptide, and nongluten proteins A and B—an advance over its landmark Array 3 test for measuring reactivity to multiple new gluten and wheat components. The new test contains biomarkers incorporated into the Array 3 along with those for four new antigens to help physicians pinpoint the trigger for reactivity and allow patients to eliminate offending foods earlier, reducing the likelihood of intestinal damage.
