On diabetic foot, wound healing, amputation prevention, and the merger of consumer tech with medical devices
In 1,052 patients with diabetic foot ulcers, ten inflammation- and nutrition-derived ratios from routine labs tracked with amputation — and a machine-learning model combining them reached an AUC of 0.894. A cheap blood draw may help forecast which limbs are at risk.
Three new papers converge on a two-cent idea: the neutrophil percentage-to-albumin ratio (NPAR) measures the balance between inflammatory injury and nutritional reserve — tracking both how bad the diabetic foot is now and how the patient fares over years. Plus a clear-eyed look at why AI-driven precision nutrition isn't here yet, and what it will take.
An email from Ben Lipsky brings new biomarker data — IL-17, IL-12p70, HMGB1, IL-8, CRP — that may be the strongest case yet for splitting "moderate" and "severe" diabetic foot infections in the IDSA and WIfI classification.
A novel inflammation-nutrition biomarker — the neutrophil percentage-to-albumin ratio (NPAR) — shows strong association with diabetic foot ulcer risk in a 1,002-patient study from Xi'an, China, reinforcing that what patients eat and how they inflame are inseparable in the diabetic foot.
When we talk about Chronic Limb-Threatening Ischemia (CLTI), we often focus on what we can see on an angiogram. But what is actually happening inside those vessels at a microscopic level? A comprehensive histopathological analysis of amputated limbs is shedding new light on the specific patterns of arterial obstruction that lead to limb loss. This... Continue Reading →
Peripheral artery disease (PAD) is one of the most devastating complications of diabetes—contributing to ischemic pain, functional decline, and, in severe cases, amputation. Despite its prevalence, early detection remains elusive, and clinicians continue to search for simple, reliable markers of risk. A new multicohort study led by Wang and colleagues now shines a spotlight on... Continue Reading →
Thermometry remains a cornerstone in the detection and monitoring of Charcot neuro-osteoarthropathy (CNO)—a frequently silent, yet limb-threatening complication of diabetes. But what if we could go deeper than skin-level heat? A new study by Eleftheriadou et al., published online in Technology in Wound Care, explores the reliability of microwave radiometry (MWR) as a tool for internal tissue temperature measurement in...

Diabetic wounds present one of the most complex and persistent challenges in modern medicine, often leading to prolonged inflammation and impaired healing. A recent study by Meng et al. (2025) introduces a potentially groundbreaking solution: a smart, MMP-9-responsive hydrogel that releases M2 macrophage-derived exosomes (M2-Exos) in response to the inflammatory microenvironment of diabetic wounds. This innovation has the potential... Continue Reading →
A recent review in Medicina highlights the promising role of sodium-glucose cotransporter 2 inhibitors (SGLT2-i) in diabetic foot prevention, presenting a detailed analysis of their physiological impact and potential benefits. Diabetic foot ulcers and related complications remain significant challenges, contributing to high healthcare costs and morbidity. SGLT2-i, originally developed for blood glucose management in diabetes,... Continue Reading →
Diabetic foot infections (DFIs) are a critical concern for individuals with diabetes, often leading to severe complications and increased healthcare costs. A recent meta-analysis by Yu-Ting Wang and colleagues, published in the journal Wounds in December 2023, sheds light on the role of inflammatory markers in detecting DFIs, which could pave the way for improved...
