Article Synopsis
  • Venous leg ulcers (VLUs) and diabetic foot ulcers (DFUs) pose significant health care challenges, prompting the need for advanced treatments like cellular, acellular, and matrix-like products (CAMPs), including polylactic acid (PLA).
  • A retrospective study assessed the effectiveness of PLA compared to established CAMPs, using data from three wound care clinics and involving 131 chronic wounds that had been untreated for 12 to 52 weeks.
  • Results indicated that PLA significantly reduced healing time and improved healing rates for both DFUs and VLUs, outperforming traditional treatments such as collagen dressings and fish skin grafts.

Introduction: Diabetic foot ulcers (DFU) are a devastating complication of diabetes. There are numerous challenges with preventing diabetic foot complications and barriers to achieving the care processes suggested in established foot care guidelines. Multi-faceted digital health solutions, which combine multimodal sensing, patient-facing biofeedback, and remote patient monitoring (RPM), show promise in improving our ability to understand, prevent, and manage DFUs.

Introduction: CAMPs are used for treating refractory DFUs where other treatments have failed. PLA is a CAMP that has demonstrated effectiveness in promoting healing in burns and acute wounds.

Objective: A single-center, prospective, randomized controlled trial comparing PLA-guided closure matrices versus collagen dressings was conducted to assess healing of Wagner grades 1 and 2 DFUs.

Diabetes and its complications, particularly diabetic foot ulcers (DFUs), pose significant challenges to healthcare systems worldwide. DFUs result in severe consequences such as amputation, increased mortality rates, reduced mobility, and substantial healthcare costs. The majority of DFUs are preventable and treatable through early detection.

Introduction: DFUs remain a cause of significant morbidity.

Objective: This is the third of 3 planned articles reporting on a prospective, multicenter, randomized controlled trial evaluating the use of omega-3-rich acellular FSG compared with CAT in the management of DFUs.

Materials And Methods: A total of 102 patients with a DFU (n = 51 FSG, n = 51 CAT) participated in the trial as ITT candidates, with 77 of those patients included in the PP analysis (n = 43 FSG, n = 34 CAT).

Objective: This is the second of 3 planned articles reporting on a prospective, multicenter, randomized controlled trial assessing the efficacy of fish skin graft in the management of diabetic foot ulcers in comparison with the standard of care (collagen alginate dressing).

Materials And Methods: The primary end point of this prospective randomized trial is the number of closed wounds at 12 weeks.

Results: As of the time of this writing, 94 patients had completed the protocol.

Introduction: Omega-3-rich fish skin grafts have been shown to accelerate wound healing in full-thickness wounds.

Objective: The goal of this study was to compare the fish skin graft with standard of care (SOC) using collagen alginate dressing in the management of treatment-resistant diabetic foot ulcers (DFUs), defined as superficial ulcers not involving tendon capsule or bone.

Materials And Methods: Patients with DFUs who were first treated with SOC (offloading, appropriate debridement, and moist wound care) for a 2-week screening period were then randomized to either receiving SOC alone or SOC plus fish skin graft applied weekly for up to 12 weeks.

Diabetes mellitus affects hundreds of millions of people worldwide, each of which have up to a 25% risk of developing a diabetic foot ulcer (DFU) during their lifetime. With poor DFU healing rates using standard of care, advanced treatments are introduced to attempt to close the wound. The objective of this preliminary clinical evaluation was to evaluate lower extremity ulcers treated with a novel bioengineered wound product (BWP).

Normal wound healing is accomplished through a series of well-coordinated, progressive events with overlapping phases. Chronic wounds are described as not progressing to healing or not being responsive to management in a timely manner. A consensus panel of multidisciplinary wound care professionals was assembled to (1) educate wound care practitioners by identifying key principles of the basic science of chronic wound pathophysiology, highlighting the impact of metalloproteinases and biofilms, as well as the role of the extracellular matrix; and (2) equip practitioners with a systematic strategy for the prevention and healing of acute injuries and chronic wounds based upon scientific evidence and the panel members' expertise.

Off-loadinga diabetic foot ulcer is a cornerstone of quality wound care for diabetic patients to allow cellular growth in the wound bed. While total contact casts (TCC) have been described as the gold standard for off-loading the wound, the complexity of application and the time commitment for both application and drying have discouraged health professionals from using them. This retrospective case series, conducted in a podiatric practice, evaluated using a TCC system that helps address the three components in which guidelines should be addressed when caring for a diabetic foot: V - vascular management, I - infection management and prevention, and P - pressure relief.

Broad-spectrum metalloproteinase (MMP) reduction along with inherent aspects of an extracellular matrix (ECM) dressing can bring about improved wound healing outcomes and shorter treatment duration. Initial reports of clinical effectiveness of a new ovine-based collagen extracellular matrix (CECM) dressing demonstrate benefits in chronic wound healing. CECM dressings are processed differently than oxidized regenerated cellulose/collagen dressings.

The objective of this article is to describe the results of a comparative porcine study that evaluated the effectiveness of a gentian violet and methylene blue (GV/MB) polyvinyl alcohol (PVA) antibacterial foam dressing in debriding eschar. The authors performed an in vivo, preclinical study on eschar-covered porcine wounds. Two clinical case studies are also included.

Objective: The objective of this multicenter study was to prospectively evaluate the healing outcomes of chronic diabetic foot ulcers (DFUs) treated with PriMatrix (TEI Biosciences, Boston, Massachusetts), a fetal bovine acellular dermal matrix.

Methods: Inclusion criteria required the subjects to have a chronic DFU that ranged in area from 1 to 20 cm² and failed to heal more than 30% during a 2-week screening period when treated with moist wound therapy. For qualifying subjects, PriMatrix was secured into a clean, sharply debrided wound; dressings were applied to maintain a moist wound environment, and the DFU was pressure off-loaded.

The suitability of the ovine forestomach matrix (OFM) for the treatment of recalcitrant wounds was evaluated in 19 patients. At 12 weeks, 50% of wounds had closed, and the average reduction in surface area was 73.4%.

Unlabelled: A retrospective study involving 22 patients (31 feet) with a history of prolonged moderate to severe heel pain associated with plantar fasciitis were examined to determine if ablation of the sensory branch of the medial calcaneal nerve would result in symptomatic relief. Participants in this study were given subjective questionnaires and visual analog scales in order to rate their symptoms before and after nerve ablation using radiofrequency energy. The results showed that the mean preintervention visual analog pain score was 8.

Background: Assessing implanted biological reinforcement graft success in soft-tissue repairs is typically limited to noninvasive measurements and functional outcome measures. However, there are times when a histologic snapshot of the graft incorporation may be possible owing to a nongraft-related postoperative complication, such as hardware failure.

Methods: We histologically evaluated a 6-month biopsy sample from an Achilles tendon repair augmented with an acellular human dermal matrix (AHDM).
