a Prospective, Multicenter, Randomized Controlled Trial, With a Non-randomized Sentinel Cohort, Evaluating the Efficacy of Bioxheal, a Single-layer Placental-derived Biologic in Nonhealing Diabetic Foot Ulcers

BIOxHEAL is an investigational placental-derived biologic being evaluated for the treatment of nonhealing diabetic foot ulcers. Adults with type 1 or type 2 diabetes who have a diabetic foot ulcer that has not healed with standard wound care may be eligible to participate. Participants in the randomized phase are assigned by chance in a 2:1 ratio to receive either BIOxHEAL administered topically in combination with standard of care (SOC), or SOC alone. Treatment is administered once weekly for up to 12 weeks or until complete ulcer closure. The primary objective is to evaluate whether BIOxHEAL plus SOC increases the proportion of target ulcers achieving complete closure at Week 12 compared with SOC alone.

Custom Insole With Transcutaneous Electrical Nerve Stimulation on Clinical Outcomes of Diabetic Foot Ulcers

Diabetic foot ulcers (DFUs) are one of the serious complications of diabetes, typically resulting from neuropathy or peripheral arterial disease, and can often lead to amputation. It affects approximately 6.3% of people with diabetes globally. In Pakistan, the overall prevalence of DFUs is 16.83%, with a slightly higher rate in females. Diabetic foot ulcers are the main reason for lower extremity amputation (LEA) with non-traumatic origin, hospitalization, healthcare costs, and mortality.

On the Move: Center and Home-Based Exercise to Enhance Mobility in Diabetic Foot Ulcer Recovery

Foot ulcers and amputations are a common and feared complication for people with diabetes. People with a diabetic foot ulcer have a higher risk of dying within five years than people with diabetes without an ulcer. At least one in four people with a new diabetic foot ulcer will die within five years, largely due to cardiovascular causes. The reasons for this increased mortality involve decreased mobility. People with a recently healed diabetic foot ulcer are considered "in remission" as opposed to "cured" because the underlying medical problems (e.g., peripheral neuropathy, peripheral arterial disease) which led to their ulcer are still present. Once in remission, the current standard of care is to slowly increase ambulation with appropriate footwear so as not to promote ulcer recurrence. The problem is that people rarely return to the recommended level of mobility. The ability to safely maintain mobility with aging is critical, as immobility is the leading cause of nursing home admissions. This is a clinical trial to test the feasibility and acceptability of an exercise regimen that transitions from in-person to home-based. The investigators will also assess if this exercise regimen can increase mobility and function without increasing diabetic foot ulcer recurrence by improving mobility, lower extremity strength, lower extremity tissue perfusion and glycemic control.

Pathogenicity Factors of Staphylococcus Pettenkoferi in Foot Wounds and Osteitis in Diabetic Patients

Gram-positive cocci, particularly Staphylococcus aureus and coagulase-negative staphylococci (SCoN), are the bacteria most frequently isolated from diabetic foot ulcers. Although studies have been carried out on the role of S. aureus in the unfavorable evolution of these wounds, no studies have focused on the role of SCoN. Of the fifty or so SCoN species, not all have the same virulence potential. The role of Staphylococcus pettenkoferi is unknown, yet this bacterium is the 7th most frequently identified in diabetic foot ulcers, suggesting that it may also be involved in the pathophysiology of these infections. At Nîmes University Hospital, this bacterium is mainly identified in samples from diabetic foot ulcers or osteitis in our laboratory and 80% of the bacteria present are in biofilms.It is essential to understand the mechanisms governing these bacterial interactions and establish the true pathogenic potential of these bacteria. Recently, the Nîmes team showed that a strain of S. pettenkoferi (SP165) isolated from foot osteitis in a diabetic patient had real virulence potential. SP165 could not only produce biofilm, but could also survive in human blood, human keratinocytes and murine and human macrophages. It also caused significant embryonic mortality in a zebrafish model. A second study of 29 isolates from Nîmes University Hospital subsequently demonstrated that there were two predominant clones with different virulences. Three biofilm production profiles (rapidly and highly biofilm-producing, slowly biofilm-producing and non-biofilm-producing) and two zebrafish profiles (highly and moderately lethal) were reported by phenotypic and genomic analyses on this panel of strains. Genes for resistance, virulence and biofilm production were also found on their genomes.

Non-Invasive Testing to Evaluate Wound Healing in Diabetes

Normal group: We will collect normative data from healthy individuals to include baseline data, screening, and images. Up to 500 people will be enrolled and can include normal healthy volunteers, staff and students/trainees. Data will be collected one time with no follow up. Patient group: We will prospectively collect data using one instrument (camera) (SnapshotNIR, Kent Imaging, Calgary, Alberta, Canada). We will collect non-contact imaging data before surgeries, during surgeries (if feasible), and during follow-up clinic visits. We will collect vascular data, demographic medical history, wound characteristics and measurements, frequency of debridement, off-loading, and clinic visits from existing medical records. We will collect lab data such as cultures glycosylated hemoglobin, hemoglobin and hematocrit, ESR, CRP and eGFR obtained per standard of care. Imaging with this device is research-only.

Seltoplasmid Plus Revascularization for Diabetic Infrapopliteal Chronic Limb-Threatening Ischemia

The goal of this clinical trial is to learn whether Seltoplasmid Injection can improve outcomes after lower-extremity revascularization. Revascularization is a procedure used to restore blood flow to the leg. The study will include adults with type 2 diabetes, a foot ulcer caused by poor blood flow, and disease mainly affecting the arteries below the knee. The main questions are: * Does adding Seltoplasmid lower the risk of major amputation, another procedure to restore blood flow, or death? * What medical problems occur after treatment with Seltoplasmid? About 180 participants will undergo standard lower-extremity revascularization. After the procedure, eligible participants will be assigned by chance to one of two groups. One group will receive Seltoplasmid plus standard care. The other group will receive standard care alone. Participants in the Seltoplasmid group will receive injections into the muscles of the affected lower leg. The injections will be given on Day 0, Day 14, and Day 28. Participants will be followed for 12 months. Researchers will also assess wound healing, survival without amputation, heart and blood vessel problems, pain, and blood flow in the affected leg.

Systemic Biochemical Signature and Functional Quality Index of Calcaneal Bone Marrow Aspirate in Adults Undergoing Foot or Ankle Surgery

This observational prospective cohort study will evaluate whether routine blood tests are associated with the functional quality of calcaneal bone marrow aspirate mesenchymal stem cells in adults undergoing clinically indicated foot or ankle surgery at a university hospital in Brazil. Participants aged 40 to 80 years, with or without comorbidities, including type 2 diabetes mellitus and, when present, active Wagner grade 2-4 diabetic foot ulcers, will be eligible for inclusion. Before surgery, participants will undergo routine blood tests, including complete blood count, glucose and lipid profile, mineral-renal markers, and tissue damage markers. During the clinically indicated surgery, calcaneal bone marrow aspirate will be collected from the same operative field. Mesenchymal stem cells will be isolated and evaluated in the laboratory for clonogenic capacity, osteogenic and adipogenic differentiation, cellular senescence, and secretion of inflammatory and anti-inflammatory cytokines. A composite Functional Quality Index of Bone Marrow Aspirate (IQF-BMA) will be constructed from routine laboratory markers to characterize inflammatory, metabolic, mineral-renal, and tissue-damage burden. The primary objective is to examine the association between the IQF-BMA and mesenchymal stem cell functional outcomes, particularly clonogenic capacity. This exploratory study will not be used to guide individual treatment decisions.

Evaluating the Efficacy of Perinatal Membrane Allografts in Addition to the Standard of Care for the Treatment of Non-healing Diabetic Foot Ulcers.

The goal of this clinical trial is to learn if using perinatal tissue allografts improves healing of chronic, non-healing foot ulcers in diabetic patients. The main question that this study aims to answer is: Does the use of perinatal tissue allografts in conjunction with standard of care wound management techniques result in a higher percentage of target ulcers achieving complete closure (i.e. healing) as compared to ulcers being treated with standard of care alone after 12 weeks of treatment. One ulcer on each participant's foot will receive weekly 1) applications of perinatal tissue allografts and standard of care wound management or 2) standard of care wound management alone. Pictures of the ulcer and measurements of its size will be measured every week to track its healing progress over a total treatment period of 12 weeks. Additionally, the participants will be asked to fill out a questionnaire about the wound impacts their life and their quality of life.

Clinical Utility of an Amniotic Membrane Allograft for Diabetic Foot Ulcer Wound Management

The goal of this clinical trial is to learn if use of Orion™, a dual-layer amniotic membrane allograft, in addition to standard wound care treatment can improve patient outcomes for people over the age of 50 with diabetic foot ulcers. The study aims to determine the incidence of complete wound closure at the end of 12 weeks of treatment. Researchers will compare the outcomes between a group of people treated with standard wound care and another group treated with standard wound care in addition to the amniotic membrane allograft to see if the amniotic membrane allograft improves wound healing. During the study, participants will visit their doctor weekly over a 12 week period, which is standard for diabetic foot ulcer treatment procedures, and fill out a questionnaire measuring quality of life.
