Experimental chronic wound dressing made from human protein
If you’re trying to make a wound dressing that will be well-tolerated by the human body, you may be best off using human-derived materials. That’s the approach that German researchers have taken, creating a tropoelastin-based bandage. Tropoelastin protein molecules are produced naturally by the human body, and they’re the main building block of elastin, a biopolymer which gives the skin and organs their elastic properties. In the past, scientists have tried to reduce scarring by injecting tropoelastin directly into wounds, without much success … read more

Army Wants New Medical Gel that Seals Off Hemorrhaging Wounds on the Battlefield
Army researchers are eyeing a promising new wound-care technology that could allow soldiers to seal hemorrhaging trauma wounds on parts of the body where pressure bandages can’t stop bleeding … The Army Research Laboratory, or ARL, is providing technical oversight on a new hemostatic gel, known as StatBond, that stops uncontrolled bleeding in noncompressible areas of the body such as the groin, armpit, neck and internal organs … read more
Sustainable fabric made from tree bark could cut MRSA infection rates
A traditional Ugandan cloth that uses tree bark to make sustainable textiles could be used to treat skin wounds after new research shows it has antimicrobial properties to fight against tough infections such as MRSA … MRSA—Methicillin-resistant Staphylococcus aureus—is an infection caused by bacteria that is resistant to many different antibiotics … continue
American Biotech Labs, LLC Receives Awards
and New Approvals
AMERICAN FORK, UT, May 31, 2018 /PRNewswire/ – American Biotech Labs, LLC (ABL) has received three new awards including: Total Health Magazine’s “Award of Excellence” and two Best of State awards for “Health and Wellness” and “Medical Manufacturing“. ABL is a health and wellness biotech company that continues to innovate products for the medical and health industries and has received a number of FDA clearances for wound dressing gel products, including antibacterial products for both wound dressing and wound cleansing.
ABL has now engineered the power of silver into antimicrobial moisturizing lotions and creams. Said Keith Moeller, CEO of American Biotech Labs, “Creating lotions and creams that are made with the antimicrobial advanced healing power of silver is a pretty daunting task, but being able to keep the moisturizers at greater than 99% organic, shows the true excellence of what we have created”.
Health Canada has already approved for sales and distribution these new antibacterial lotion and cream products and distribution is anticipated to begin in the Canadian markets within the next few months. In the US markets, ABL has begun distribution of these powerful lotion and cream cosmetic products under the Silver Biotics brand of products.
Sucrose octasulfate wound dressing may speed healing in diabetic foot ulcers
Patients with a noninfected neuroischemic diabetic foot ulcer were more likely to achieve wound closure within 20 weeks when randomly assigned a sucrose octasulfate dressing vs. those assigned a standard wound dressing, according to findings published in The Lancet Diabetes & Endocrinology.
“Delayed wound healing in neuroischemic diabetic foot ulcers has been related to excess matrix metalloprotease concentrations; these proteins destroy components of the extracellular matrix and damage growth factors and their receptors that are essential for healing,” Michael Edmonds, MD, of the Diabetic Foot Clinic at King’s College Hospital in London, and colleagues wrote. “Sulfated oligosaccharides are known to have many biological activities; in particular, the potassium salt of sucrose octasulfate has been shown to inhibit matrix metalloproteases and to interact with growth factors and restore their biological functions because it has high charge density.”
Edmonds and colleagues analyzed data from 240 patients with diabetes and a noninfected neuroischemic diabetic foot ulcer of grade IC or IIC, with a wound … read more
Assessing Stress During Wound Care
Review: Assessing Stress During Wound Care in Real-Time Using Wearable Sensors
Introduction: The Stress Response in Wound Care in Diabetic Foot Ulcers
Within the last decade, the rise of diabetes in the U.S. population has been matched with a rise in diabetic foot ulcers requiring amputations. Because many of these diabetic foot ulcers develop secondary to poor wound healing and susceptibility to infection after surgery, some important risk factors have been evaluated. Stress, among other factors, has been shown not only to affect the psychological state of a patient, but also biologically to impair immunity and induce an inflammatory microenvironment within patients.
Although previous studies have measured stress by using heart rate and respiration rate during a dressing change lasting three to five minutes, no studies have continuously quantified stress in patients with diabetic foot ulcers during a routine visit. This particular study attempted to examine the stress response in patients with diabetic foot ulcers by using a chest-worn sensor displaying heart rate data. The research team relied on an algorithm to estimate stress that used changes in heart rate variability, a measurement that is taken between two consecutive R waves of an electrocardiogram.
Materials and Methods: Electrocardiographic Monitoring of Wound Dressing Changes in Diabetic Foot Ulcers
Twenty patients with diabetic foot ulcers were recruited from a wound care center and were given the BioHarness3, an FDA approved body device to evaluate single-channel electrocardiogram activity, respiration rate, posture, and core body temperature. To ensure quality control, the team used a smart phone to monitor data in a real-time fashion. This smart phone and BioHarness3 system had a biomodule that was linked to the patient’s body via a biopatch and electrocardiogram electrodes.

Wound Care Startup Could Reduce Home Health Time
A biomedical engineer and a health care entrepreneur have teamed up to improve wound care with a product designed to prevent infection and reduce the need for some post-acute care, including home health.
FM Wound Care, LLC, based in Trenary, Michigan, is awaiting U.S. Food and Drug Administration approval on a nitric-oxide-infused, self-sterilizing wound dressing designed to kill bacteria following surgery. The post-op bandage could potentially reduce the need for some care performed by home health care providers, and lower overall wound care costs.
Megan C. Frost, PhD, and entrepreneur Jeff Millin believe their product—the Sentry Wound Dressing—prevents infections by slowly releasing nitric oxide (N.O.) over the course of seven days, allowing patients to wear the same wound dressing for a week.
“If a nurse has to change a dressing, that takes quite a bit of time,” Millin explained to Home Health Care News. “If you only had to do that once every seven days as opposed to once every other day, the savings could be significant.”
