Managing chronic venous leg ulcers — what’s the latest evidence?

Managing chronic venous leg ulcers — what’s the latest evidence?

Chronic venous leg ulcers (CVLUs) affect nearly 2.2 million Americans annually, including an estimated 3.6% of people over the age of 65. Given that CVLU risk increases with age, the global incidence is predicted to escalate dramatically because of the growing population of older adults. Annual CVLU treatment-related costs to the U.S. healthcare system alone are upwards of $3.5 billion, which are directly related to long healing times and recurrence rates of over 50%.

CVLUs are not only challenging and costly to treat, but the associated morbidity significantly reduces quality of life. That makes it critical for clinicians to choose evidence-based treatment strategies to achieve maximum healing outcomes and minimize recurrence rates of these common debilitating conditions. These strategies, which include compression therapy, specialized dressings, topical and oral medications, and surgery, are used to reduce edema, facilitate healing, and avert recurrence. (more…)

Peptide nanofibers keep infections at bay

Researchers have developed a new infection-blocking material made of peptide-containing nanofibers that works against antibiotic-resistant bacteria and could one day be incorporated into wound dressings (ACS Infect. Dis. 2017, DOI: 10.1021/acsinfec​dis.6b00173).

The approach targets bacterial quorum sensing—a mode of chemical communication used by bacteria to detect other bacteria. When they sense that enough of their kind are present, they can mount an infectious attack.

Stem Cell Dynamic Therapy Could Heal Wounds

It’s necessary for the skin to heal the wounds after getting injured. For the first time, scientists discovered that the changing stem cell dynamics contribute to wound healing. The main purpose of these studies was to understand how stem cells differentiate, migrate, and proliferate to repair the tissue damage after trauma.

A team from Université libre de Bruxelles (ULB) started their research on stem cells. Professor of ULB, Dr. Cédric Blanpain MD/Ph.D, WELBIO investigator and the lead researcher of this study, defined the cellular and molecular mechanisms that play active roles in wound healing. The research report was first published in the Journal of Nature Communications.

The skin of a creature is just like an outer shield which protects the inner tissues and other organs from outer injuries. If somehow the outer shield gets disrupted then body activates a cascade of cellular and molecular event to repair the damage and restore skin integrity. ScienceDaily reported that minor defects in these events lead to improper repair causing acute and chronic wound disorders.

In the new study, scientists revealed that distinct stem cells populations contribute in healing the wound. Although it is not cleared yet how proliferation, differentiation, and migration get balanced by stem cell populations during the healing process. Co-author of this study Dr.Sophie Dekoninck said in a statement,“The molecular characterization of the migrating leading edge suggests that these cells are protecting the stem cells from the infection and mechanical stress allowing a harmonious healing process”.

One Doctor Exploring Wound Care on Earth and in Space

In laboratories all across the globe, scientists are uncovering new and exciting breakthroughs in the realm of wound healing.

For instance, a team out of Texas is blinding bacteria to prevent their spread. Meanwhile, a collective of doctors from the U.K. recently developed some intriguing new vacuum tech to treat chronic ulcers. There’s even been research into drug treatments, like how opioids may actually prevent proper wound care.

Each team has taken a different approach or tackled a unique situation or medical ailment, and that ensures a more well-rounded coverage that helps a larger pool of patients. However, few scientists have a more grand scope than Ronke Olabisi, a professor of biomedical engineering at Rutgers University.

Reaching for the stars

As the university explained in a recent press release, Olabisi is hard at work on several projects aimed at improving wound healing both on earth and during manned space missions. During space travel, especially as astronauts spend months at a time in stations, the lack of gravity has a huge impact on the human body. Muscle and bones will actually start to deteriorate, and tissues will lose much of their elasticity. Olabisi’s main goal is to study in-depth why this occurs and how to fix, and she believes she can apply much of the same knowledge to wound care on Earth.

Crawford bags FDA clearance for wound dressing that will ‘save limbs’

Crawford Healthcare, one of the biggest makers of advanced wound-care products in the UK, has won clearance from US regulators for a medical dressing that it says will “save limbs”.

The product, called KerraCel AG, soaks up fluid and bacteria from nasty, oozing wounds and locks it away as a gel. It is also the only dressing of its kind to contain silver at a special concentration to kill all bacteria – even those resistant to antibiotics – that prevent chronic wounds, such as diabetic ulcers and pressure sores, from healing.

Reduction of 50% in Diabetic Foot Ulcers With Stem Cells

Diabetic Foot Ulcers

MUNICH — Local injection of mesenchymal stem cells derived from autologous bone marrow shows promise in healing recalcitrant neuropathic diabetic foot ulcers, a novel study from Egypt shows.

Presenting the results at the European Association for the Study of Diabetes (EASD) 2016 Annual Meeting, Ahmed Albehairy, MD, from Mansoura University, Egypt, said: “In patients who received the mesenchymal stem cells, ulcer reduction was found to be significantly higher compared with patients on conventional treatment after both 6 weeks and 12 weeks of follow-up. This is despite the fact that initial ulcer size was larger in the stem-cell–treated group.” (more…)

Better Skin Grafts – take only one layer

skin grafts take one layer

Research shows that a skin-graft harvesting system aids chronic wound recovery and reduces care costs by accelerating the healing process.

More than six million cases of chronic wounds cost $20 billion each year in the United States. Diabetic ulcers, pressure sores, surgical site wounds, and traumatic injuries to high-risk patients account for most wounds that won’t heal. (more…)

Using fat to help wounds heal without scars

fat heal scars adipogenic culture

Philadelphia – Doctors have found a way to manipulate wounds to heal as regenerated skin rather than scar tissue. The method involves transforming the most common type of cells found in wounds into fat cells – something that was previously thought to be impossible in humans. Researchers began this work at the Perelman School of Medicine at the University of Pennsylvania, which led to a large-scale, multi-year study in connection with the Plikus Laboratory for Developmental and Regenerative Biology at the University of California, Irvine. They published their findings online in the journal Science on Thursday, January 5th, 2017.Fat cells called adipocytes are normally found in the skin, but they’re lost when wounds heal as scars. The most common cells found in healing wounds are myofibroblasts, which were thought to only form a scar. Scar tissue also does not have any hair follicles associated with it, which is another factor that gives it an abnormal appearance from the rest of the skin. Researchers used these characteristics as the basis for their work – changing the already present myofibroblasts into fat cells that do not cause scarring. (more…)

Skin substitutes: Understanding product differences

Skin substitutes (also called tissuebased products and dermal replacements) are a boon to chronic wound management when traditional therapies have failed. When selecting skin substitutes for their formularies, wound care professionals have many product options—and many decisions to make.

Repair of skin defects has been a pressing concern for centuries. As early as the 15th century BC, Egyptian physicians chronicled procedures and herbal treatments to heal wounds, including xenografts (skin from another species). The practice of applying allografts (human cadaver skin) to wounds was first documented in 1503. In 1871, autologous skin grafting (skin harvested from the the person with the wound) was tried. Next came epithelial- cell seeding, which involves scraping off the superficial epithelium of healthy skin and transplanting the cells onto the wound. (more…)
