  Prediabetes: The Silent Signal You Can Change 13.09.2026 26dk

  Prediabtes isn’t “ Almost Diabetes” . This episode explains how type 2 diabetes often begins years before diagnosis as prediabetes — a compensatory metabolic state where insulin resistance, pancreatic stress, liver overproduction of glucose, and visceral fat-driven inflammation quietly disrupt glucose control. You’ll learn the diagnostic thresholds (A1c 5.7–6.4%, fasting glucose 100–125 mg/dL, 2‑hour OGTT 140–199 mg/dL), why different tests can identify different people, who should be tested, and which clinicians to involve (PCP, endocrinologist, dietitian, diabetes prevention programs). The episode emphasizes prevention: lifestyle-based diabetes prevention programs can reduce progression, metformin is not automatic, and early action can change your metabolic trajectory — protecting overall health and reducing future foot and limb complications.

  Why Diabetic Foot Ulcers Can’t Finish the Job: The Microbial Clearance Problem 11.09.2026 16dk

  This episode explores why some diabetic foot ulcers remain inflamed yet fail to clear microbes, distinguishing contamination, colonization, local infection, and clinical infection. It explains how immune dysregulation, neutrophil extracellular traps (NETs), macrophage dysfunction, biofilm, ischemia, hypoxia, neuropathy, and necrotic tissue create an ecosystem that prevents healing.The episode emphasizes that antibiotics alone are not enough: effective care requires assessing perfusion, offloading, debridement, glycemic and systemic management, targeted antimicrobials when indicated, and ongoing surveillance to change the wound trajectory.

  Why You Can't Just Glue a Diabetic Foot Ulcer Closed 09.09.2026 16dk

  In this episode Dr. G explains why tissue adhesives like cyanoacrylates (e.g., Dermabond) work well for clean, superficial, low‑tension wounds but are inappropriate for diabetic foot ulcers. Diabetic ulcers involve neuropathy, poor perfusion, infection risk, dead space, undermining and impaired healing biology that glues cannot fix.Key takeaways: adhesives only bond superficial skin edges and do not treat infection, necrosis, ischemia or structural problems; using glue can trap drainage and mask deeper issues; tissue glue may last days but is not a cure for complex diabetic wounds.
• 
  Dead Space in the Diabetic Foot: The Hidden Cavity That Stops Healing 08.09.2026 21dk

  Dr. G explains what dead space is — a residual tissue cavity after tissue loss or separation in the diabetic foot — why it matters, and how it differs from abscesses, undermining, and tunneling.He outlines how to recognize dead space (probing, persistent drainage, imaging), its impact on healing, and practical management strategies including debridement, drainage, infection control, offloading, and prevention.
• 
  TEWL Reveals Hidden Risk of Diabetic Foot Ulcer Recurrence 07.09.2026 27dk

  Dr. G explains transepidermal water loss (TEWL) and why a clinically closed diabetic foot ulcer can still have a compromised skin barrier. He outlines how TEWL reflects epidermal function, how diabetes and neuropathy impair skin recovery, and why “functional closure” differs from simple epithelialization.A multicenter study found higher TEWL at recently closed ulcer sites was linked to increased and earlier recurrence, suggesting TEWL could help guide extended offloading, closer follow‑up, and targeted care to reduce re‑ulceration risk.

  Forgotten Infection Friday: The Case of Erysipelothrix 05.09.2026 41dk

  This episode explains Erysipelothrix rhusiopathiae, an animal-associated bacterium that can enter through minor skin breaks—often from fish, meat, or livestock exposure—and cause a localized lesion called erysipeloid.It highlights diagnostic traps in diabetic foot care, the importance of occupational history (remember FISH: Fish exposure, Inoculation, Slowly expanding lesion, Heart involvement), the organism's intrinsic resistance to vancomycin, and the potential for systemic disease including endocarditis.
• 
  When a Toe Is More Than Tissue: The Ethics of Diabetic Foot Consent 03.09.2026 18dk

  Dr. G explains why informed consent in diabetic foot care is more than paperwork: it’s a time-sensitive conversation about capacity, risks, alternatives, and what happens if treatment is delayed.The episode covers capacity versus competency, surrogate and physician consent in emergencies, the emotional weight of amputation decisions, and a four-phase consent model to help patients understand trajectories and make informed choices.
• 
  Applying Newton’s Laws to Diabetic Foot Ulcers 02.09.2026 41dk

  In this episode Dr. G explains how Newton’s laws of motion illuminate why some diabetic foot ulcers heal and others recur. He connects concepts like force, pressure, shear, and ground reaction forces to real-world biomechanics, footwear, and offloading strategies.The episode focuses on practical takeaways: managing mechanical loading through appropriate offloading devices, understanding patient activity and adherence, and designing prevention plans so healed wounds stay closed.

  LIMBWatch Series: Dr. Jared Adams MD,PhD : Your Story Could Save a Limb: Inside the New Diabetic Foot Ulcer Patient Registry STEADY 31.08.2026 49dk

  Your Story Could Save a Limb: Inside the New Diabetic Foot Ulcer Patient Registry What if the most important piece of diabetic foot ulcer research isn’t another clinical endpoint—but the patient’s story? In this special episode of LIMBWatch, Dr. G sits down with Dr. Jared Adams, Senior Vice President of Global Medical Affairs, Digital, and Technology at Alira Health, to explore a powerful new approach to diabetic foot ulcer research: building a patient-centered registry that follows the real-world story of people living with DFUs. A diabetic foot ulcer is never “just a wound.” It can affect mobility, employment, sleep, mental health, independence, finances, transportation, family members, and the ability to access care. Yet many of those experiences never make it into the medical record. Dr. Adams explains why registries can fill that gap by connecting patient-reported experiences, clinical information, wound images, healthcare records, and eventually claims data to create a much more complete picture of what actually happens to people living with DFUs. Together, Dr. G and Dr. Adams discuss why clinical trials and real-world evidence serve different purposes, why the patients seen in everyday practice often look very different from carefully selected clinical-trial populations, and how understanding the entire pathway of care may help identify opportunities to intervene before a patient reaches hospitalization, recurrence, or amputation. One of the most powerful themes of the conversation is co-design. Patients aren’t simply being asked to participate in research—they are being invited to help determine what the research should ask in the first place. The registry team is currently conducting remote, compensated one-hour interviews with people living with diabetic foot ulcers to learn what researchers may be missing. Participants can share everything from how their ulcer began and how their care was coordinated—or fragmented—to the emotional, financial, and practical realities that don’t appear in a wound measurement. And compensation matters. As Dr. Adams explains, patients are being compensated because lived experience is expertise. Their time, knowledge, and experiences have value. These interviews are separate from enrollment in the registry itself. The goal is to listen first, learn from patients, and use those insights to help build a registry capable of following thousands of people over many years. The conversation also explores the potential of smartphones, AI, remote monitoring, and patient-generated data to become part of the future wound-care toolkit—but with an important reminder: technology cannot replace the human being in the loop. Perhaps the most important message of the episode is this: Every toe has a story. And behind every wound is a person. If we can capture those stories, connect them to clinical evidence, and understand the pathways that lead toward healing—or toward limb loss—we may be able to move from simply treating diabetic foot ulcers to truly understanding them. From surveillance before salvage to fragmentation of care, insurance barriers, patient-reported outcomes, quality of life, limb preservation, and the future of real-world evidence, this episode asks a fundamental question: What could happen if we finally started measuring what matters most to the people living with diabetic foot ulcers? If you or someone you know is living with a diabetic foot ulcer and would like to learn more about participating in the patient interviews, visit STEADY DFU Patient Registry  Your story may reveal the question researchers didn’t know they needed to ask. Your voice matters. And it could help change what happens to the next patient. Correction: The episode incorrectly stated that US citizenship is required for participation in STEADY. US residency is required, but US citizenship is not required. Citizenship

  LIMBWatch Series: Dr. Sukoff, Dr. Hanley & Dr. Warren - LIMBWatch: From Chronic Wound to Limb Preservation — The Science Behind Lavior 24.08.2026 41dk

    Episode Summary In this episode of LIMBWatch, we go beyond the wound itself to explore the science, clinical challenges, and innovations shaping the future of limb preservation. We are joined by the team behind Lavior, including biomedical scientist and Chief Scientific Officer Dr. David Warren, wound care and hyperbaric medicine specialist Dr. Hanley, wound care podiatrist Dr. Sukoff, and National Sales Director Ashlyn Tapley.  The conversation explores how Lavior was inspired by the healing properties of Inula viscosa, a medicinal plant with centuries of traditional use, and how the company developed a bioengineered hydrogel designed to address key challenges in chronic wound healing. We dive into the inflammatory phase of wound healing, antimicrobial and anti-inflammatory activity, bioactive compounds, wound-bed preparation, diabetic foot ulcers, surgical wounds, burns, pressure injuries, venous ulcers, and other complex wounds. The discussion also examines how Lavior is being used alongside negative pressure wound therapy, collagen, alginate, skin substitutes, PRP, total contact casting, and other wound-care modalities. Importantly, this episode goes beyond any single product. We discuss the fundamentals that remain critical to limb preservation: early intervention, vascular assessment and revascularization when necessary, meticulous wound-bed preparation, infection and biofilm management, moisture balance, and—perhaps most importantly—offloading. The episode also explores where wound care may be headed over the next decade, including new Lavior formulations incorporating collagen and calcium alginate, and the growing need for clinicians who understand chronic wounds and amputation prevention. And in one of the episode’s most memorable moments, Dr. Hanley shares a powerful message for people living with diabetes: “You can either have diabetes, or it can have you.” From the science of chronic inflammation to the human impact of amputation, this episode asks an essential LIMBWatch question: How early can we intervene—and what can we do differently to preserve the limb before the wound becomes a life-changing event? Episode Description Chronic wounds don’t just threaten skin—they can threaten mobility, independence, quality of life, and ultimately the limb. In this episode of LIMBWatch, we sit down with the Lavior team to explore a different approach to chronic wound healing and limb preservation. We discuss the science behind Lavior’s Inula viscosa-derived technology, its proposed antimicrobial and anti-inflammatory properties, the role of chronic inflammation in stalled wounds, and how the product is being incorporated into the management of diabetic foot ulcers and other complex wounds. We also tackle the clinical realities that matter beyond any dressing: early intervention, wound-bed preparation, vascular status, offloading, infection control, and multidisciplinary limb-salvage care. From diabetic foot ulcers and surgical wounds to ischemic wounds, pressure injuries, burns, and difficult-to-heal wounds, this conversation examines where innovation may fit into modern wound care—and where the fundamentals of limb preservation remain non-negotiable. Because saving a limb doesn’t start at amputation. It starts much earlier. 🎙️ LIMBWatch | Diabetic Foot Files This episode is for educational purposes and does not constitute medical advice or an endorsement of any specific product.
