Dr. Gabrielle Hutchison Donaldson dives into the 2025 Nobel Prize in Physiology or Medicine for discoveries about regulatory T cells (T‑regs), explaining why these immune brakes matter and how they control self‑tolerance. The episode links T‑reg biology to diabetes and diabetic foot ulcers, covering mechanisms, early T‑reg therapies, and how boosting regulatory pathways could reduce chronic inflam...

Dr. G explains erysipelas — the classic shiny, well-demarcated red leg — covering its causes (mainly streptococcal), distinguishing it from cellulitis and other mimics, initial investigations, and outpatient vs inpatient treatment strategies. Special considerations for people with diabetes (imaging, admission thresholds, and limb salvage), prevention of recurrence, and clear red flags for urgent s...

Dr. G explains the key differences between Kling (conforming) and Kerlex (bulky padding), when to use each, and how wrapping technique and tension can affect perfusion and healing in diabetic feet. Includes practical application steps, pressure checks to avoid ischemia, tips for moisture and allergy management, and clinical pearls for better wound outcomes and patient education.

This episode explains the piezoelectric effect—how mechanical stress creates tiny electrical signals—and how those signals guide cell migration, angiogenesis, collagen deposition, and epithelialization in wound healing. It describes how diabetes weakens natural bioelectrical cues through neuropathy, poor circulation, and collagen changes, and reviews clinical approaches that restore or mimic these...

Dr. G explains when to use IV versus oral antibiotics for diabetic foot infections, covering severity-based choices, common empirical regimens, and why wound cultures matter. The episode reviews pharmacokinetics, expected timelines for improvement (48–72 hours), typical durations for soft-tissue infection and osteomyelitis, and criteria to step down from IV to oral therapy. It also highlights moni...

Dr. G explains drop foot — the inability to lift the front of the foot — and why people with diabetes are at special risk due to neuropathy, compression, and poor circulation. This episode covers how to recognize drop foot, key diagnostic steps (EMG, imaging, vascular testing), urgent red flags, and a step-by-step treatment plan including AFOs, FES, physical therapy, surgical options, wound care,...

Dr. G interviews Emmy winning journalist Kym  Nicholas, CEO and co‑founder of the Global PAD Association, about peripheral arterial disease (PAD), its strong link to diabetes, common misdiagnoses, and why early vascular evaluation can prevent unnecessary amputations. They discuss patient stories, systemic gaps in care, lifestyle interventions like supervised walking programs, global best prac...

In this episode of Diabetic Foot Files, Dr. G explores how existing medications — from metformin and insulin to statins, fentanyl, sildenafil, doxycycline and nitric oxide donors — are being repurposed to help heal stubborn diabetic foot ulcers. We review the biology behind each drug, early clinical evidence, and why topical formulations may offer targeted benefits with minimal systemic exposure....

This episode explores new randomized evidence that semaglutide, a GLP-1 receptor agonist used for diabetes and weight loss, can improve walking distance and quality of life for people with type 2 diabetes and symptomatic peripheral arterial disease (PAD). The landmark STRID trial showed median gains of about 26 meters (mean ~40 m) in walking distance over a year, along with better pain scores and...

In this episode of Diabetic Food Files we explain how peripheral arterial disease (PAD) and chronic kidney disease (CKD) interact in people with diabetes to worsen circulation, slow wound healing, and raise the risk of infection and limb loss. We outline the key symptoms to watch for, recommended screening tests (ABI/toe–brachial index, urine albumin-to-creatinine ratio, eGFR), and why every perso...

This episode of Diabetic Foot Files explores peripheral arterial disease (PAD) in people with diabetes — its history, how diabetes accelerates arterial damage, the biology behind impaired wound healing, and clinical clues to distinguish ischemic from neuropathic ulcers. We cover bedside tests (ABI, TBI, TcPO2), modern revascularization options, medical and lifestyle management, and emerging therap...

Dr. G explains how nicotine — from cigarettes, vapes, pouches, and nicotine replacement products — reduces blood flow, disrupts immune and cellular repair, and slows or worsens healing in diabetic foot wounds. He summarizes the science, lists nicotine-containing products, and gives practical, evidence-based guidance for clinicians and patients on screening, cessation options, and wound-care strate...

A focused look at fifth metatarsal ulcers in diabetic patients — why they form, how the peroneus brevis and lateral biomechanics drive injury, and the clinical strategies to heal and prevent recurrence.

This episode explains Monckeberg ("Mockingbird") sclerosis—a medial arterial calcification common in diabetes and chronic kidney disease—how it stiffens arteries without narrowing the lumen, and why it can make ABI results falsely reassuring. Learn how to spot the classic railroad-track calcifications on x-ray, which vascular tests to use instead (toe-brachial index, duplex ultrasound, TcPO2), and...

This episode explores how the current culture around diabetic foot ulcers drives unnecessary amputations and presents a practical, evidence-based roadmap to change it. Dr. G outlines the data supporting multidisciplinary care, step-by-step clinical checklists for rapid triage and management, system-level referral pathways, and patient engagement strategies to make major amputation rare.

Dr. G explores exosomes—small, cell‑derived vesicles—and how they may accelerate diabetic foot ulcer healing by modulating inflammation, promoting angiogenesis, boosting cell proliferation, and improving matrix remodeling. Strong and consistent animal data show faster closure and better vascularity, and early human trials are beginning. Yet important hurdles remain: standardization of sources and...

Episode walkthrough of local anesthesia for diabetic foot procedures: why blocks are essential even in neuropathic patients, how infection changes pain perception, and the physiology and practical reasons to use anesthesia. Concise techniques and tips for ankle, digital, posterior tibial, saphenous, sural, superficial and deep peroneal blocks, recommended local anesthetic volumes and durations, ke...

This episode explains how dressings can cause irritant or allergic contact dermatitis in diabetic foot ulcers, how to tell the difference from infection, and the red flags to watch for. Dr. G covers immediate management (remove the culprit, gentle cleansing, topical steroids, antihistamines), safer dressing alternatives (silicone-based, non-adhesive, latex-free, and antiseptic options), and preven...

Dr. G explains how common NSAIDs (ibuprofen, naproxen, celecoxib, etc.) can interfere with the wound-healing process in people with diabetes by blocking prostaglandins, delaying fibroblast recruitment, reducing angiogenesis and collagen deposition, and increasing TNF-alpha—leading to stalled ulcers and higher infection risk. The episode reviews safer pain-management alternatives (acetaminophen, to...
