Scientists have engineered a synthetic biodegradable foam that can suppress inflammation, promote blood vessel growth and support the rapid healing of chronic skin wounds,...
By Ben Coxworth April 04, 2022 There’s phenols in them thar blueberries Depositphotos For some time now, blueberries have been claimed to slow the progression of memory loss. A new study now suggests that compounds found in the berries may also help heal chronic wounds such as diabetes-related skin pressure ulcers. In order for a wound...
The sensor detects temperature, pH, bacteria type, and inflammatory factors specific to chronic wounds within 15 minutes, allowing for fast and accurate wound assessment. Given the rapidly aging population, healthcare providers are seeing more patients suffering from non-healing wounds such as diabetic foot and chronic venous leg ulcers. Estimates suggest that about 2% of the...
FRONTIERS How can doctors make sure a dressed wound is healing without taking off the bandage? This is a conundrum, because removing a bandage can disrupt the healing process. Technology presented in a new study in open-access journal Frontiers in Physics could help. This new ‘smart bandage’ contains a sensor that can very sensitively measure wound moisture...
SEPTEMBER 28TH, 2021 CONN HASTINGS MATERIALS, MEDICINE, SURGERY A team of scientists at Purdue University created a microneedle patch that can deliver oxygen and bactericidal agents to chronic wounds. The bacterial biofilms that form over non-healing wounds, such as foot ulcers, are a formidable barrier to successful treatment. Such wounds are typically hypoxic and the bacteria within...
MICHIGAN STATE UNIVERSITY EAST LANSING, Mich. – Tens of millions of patients around the world suffer from persistent and potentially life-threatening wounds. These chronic wounds, which are also a leading cause of amputation, have treatments, but the cost of existing wound dressings can prevent them from reaching people in need. Now, a Michigan State University...
IMAGE: WOUND. An international team of researchers led by Johns Hopkins has shown that a topical gel made from a class of common blood pressure pills that block inflammation pathways speeds the healing of chronic skin wounds in mice and pigs. A report of the findings, published Oct. 16 in the Journal of Investigative Dermatology, marks efforts...
A large proportion of chronic wounds treated by the NHS are diabetic foot ulcers The new gel aims to close ulcers that have failed to heal for months or even years Initial results suggest nine out of ten unhealed wounds responded to the new gel A gel made from a cocktail of the patient’s...
