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.

Wound Photography – How it Benefits Clinical Documentation

wound photography

Accurate assessment and documentation of wounds is essential for developing a comprehensive plan of care. Photography now plays a key role in wound care. The use of digital photography has enhanced the reliability and accuracy of wound documentation. Though a wound assessment in patient files includes details such as location, depth, odor, condition of surrounding tissue and other details, a visual record can be worth even more.

Digital photography is becoming a more prevalent documentation tool. According to an article published in McKnight’s, forensic nursing experts recommend using photographs to document injury. The photos show both how an injury occurred and how it is healing.

The National Pressure Ulcer Advisory Panel (NPUAP) also supports photography as a more accurate means for assessment of wound dimensions and wound base over time.

A visual confirmation to the written record, these images:

  • Facilitate better diagnosis
  • Enhance clinical documentation
  • Help to monitor the progress of wound healing
  • Help prevent litigation in wound management
  • Allow inter-disciplinary communication among the wound care team

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.

Management of Patients With Venous Leg Ulcers

It is well documented that the prevalence of venous leg ulcers (VLUs) is increasing, coinciding with an ageing population. Accurate global prevalence of VLUs is difficult to estimate due to the range of methodologies used in studies and accuracy of reporting.1 Venous ulceration is the most common type of leg ulceration and a significant clinical problem, affecting approximately 1% of the population and 3% of people over 80 years of age2 in westernised countries. Moreover, the global prevalence of VLUs is predicted to escalate dramatically, as people are living longer, often with multiple comorbidities. Recent figures on the prevalence of VLUs are based on a small number of studies, conducted in Western countries, and the evidence is weak. However, it is estimated that 93% of VLUs will heal in 12 months, and 7% remain unhealed after five years.3 Furthermore, the recurrence rate within 3 months after wound closure is as high as 70%.4-6 Thus, cost-effective adjunct evidence-based treatment strategies and services are needed to help prevent these ulcers, facilitate healing when they occur and prevent recurrence.

The impact of a VLU represents social, personal, financial and psychological costs on the individual and further economic drain on the health-care system. This brings the challenge of providing a standardised leg ulcer service which delivers evidence-based treatment for the patient and their ulcer. It is recognised there are variations in practice and barriers preventing the implementation of best practice. There are patients not receiving appropriate and timely treatment in the initial development of VLUs, effective management of their VLU and preventing recurrence once the VLU has healed.

Health-care professionals (HCPs) and organisations must have confidence in the development process of clinical practice guidelines and have ownership of these guidelines to ensure those of the highest quality guide their practice. These systematic judgments can assist in policy development, and decision making, improve communication, reduce errors and improve patient outcomes.

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…)

Don’t go it alone

A fundamental rule of wound care is to treat the “whole” patient, not just the “hole” in the patient. To do this, we need to focus on a holistic

approach to healing, which means evaluating everything that’s going on with the patient—from nutrition, underlying diseases, and medications to activity level, social interactions, and even sleep patterns.

We know that as specialists, we’re expected to do all of these things. But in the real world, we can’t be specialists in all areas. That’s where the team concept comes in. In fact, the team approach is imperative for helping us heal our patients’ wounds and achieve our overall goal of improving patient outcomes. (more…)
