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.
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.
Vitamin D has been medicine for millennia — we just didn't know it. A tour through its history, its biology, and what the evidence now says about its role in diabetic foot ulcer healing.
We talk a lot about the big-ticket items in diabetic peripheral neuropathy (DPN)—glucose control, hemoglobin A1c, advanced glycation end products. But what about the stuff sitting quietly in your multivitamin? A new review from Ntoga and colleagues out of the Diabetic Foot Clinic at Democritus University of Thrace—working with collaborators at Aristotle University of Thessaloniki—makes...

For millions living with diabetes, foot ulcers are more than a painful inconvenience—they’re a serious, often underestimated health threat. With sluggish healing and high infection risks, DFUs dramatically increase the likelihood of hospitalization and amputation. But a recent clinical trial points to a simple, well-known compound—vitamin D—as a powerful ally in the battle against DFUs.... Continue Reading →
A Nutrient-Driven Balancing Act: How Serine Tunes Stem Cell Fate in Skin Repair Novak et al., 2025, Cell Metabolism ⚖️ Serine, Stress, and Skin: A New Paradigm What if a single non-essential amino acid could pivot stem cells from regenerating hair to healing wounds? A striking new study from Elaine Fuchs’ group at Rockefeller University... Continue Reading →
We’ve long been told to take our vitamins—but recent research suggests we might also want to “prescribe” them directly to our most persistent microbial adversaries. A striking 2025 study published in BMC Microbiology reveals that vitamin C (sodium ascorbate) may do more than bolster immune function: it can weaken drug-resistant bacterial biofilms and restore the efficacy of...

If you’ve ever had a routine blood test, you’ve probably seen numbers for cholesterol, hemoglobin, or even zinc. But have you ever checked your CONUT score? No, it’s not a secret menu item at Shake Shack—it’s actually a critical measure of nutritional health that may be the missing link in healing diabetic foot ulcers (DFUs). What... Continue Reading →
Screenshot Recent research by Skórka et al. (2024) highlights an essential yet often overlooked aspect of wound healing: the larger the wound, the greater the risk of nutritional deficiency. This finding underscores the critical need for integrating nutritional assessment and intervention into the care of patients with chronic wounds, such as those caused by diabetic foot...
