Co-Creating the Foot Selfie– in Peru! A Patient-Centered App to Prevent Diabetic Foot Ulcers — Built With, Not For #FootSelfie #ActAgainstAmputation #DiabeticFoot #GlobalHealth @usc_vascular @alpslimb

A new paper in BMC Health Services Research describes how we co-created a Foot Selfie app with, not for, people living with diabetes, caregivers, and clinicians in urban Lima and semi-rural Piura, Peru. Here is how the end-users redesigned remote diabetic foot surveillance to fit the rooms where it actually happens.

A Toe-and-Flow Welcome in Dublin: Standing Room Only at The Beaumont Multidisciplinary #DiabeticFoot Symposium #ActAgainstAmputation

Notes from the Beaumont Multidisciplinary Diabetic Foot Symposium in Dublin (18 June 2026) — a true toe-and-flow gathering across vascular surgery, podiatry, endocrinology and infectious diseases, where the watchword was remission, not cure.

Old Drugs, New Logic: Could #Metformin Be a Causal Repair Switch in the #DiabeticFoot? A #microRNA + #DrugRepurposing #ActAgainstAmputation

A new multi-omics preprint uses Mendelian randomization to argue that six circulating miRNAs causally regulate peripheral artery disease in the diabetic foot—and flags metformin as the most translationally tractable repurposing candidate. A nice piece of computational scaffolding, with the usual in-silico caveats.

Zero Amputations. In One of the Toughest ZIP Codes in Diabetes America. #ActAgainstAmputation

Four years of data from MLK Community Healthcare show what happens when you build diabetic foot care around the patient — in exactly the place the map says amputations should be worst.

A Foot Ulcer Is a Whole-Body Diagnosis: New 5698 Patient Cohort Puts DFU Survival Back in the Cancer Conversation — But There’s Hope #DiabeticFoot #ActAgainstAmputation #ToeandFlow

A new 5,698-patient real-world cohort from Valladolid (Del Río-Solá et al., Adv Wound Care 2026) reports 61.8% five-year survival overall, falling to 32.1% after major amputation — and concludes the diabetic foot ulcer should be treated as a marker of advanced systemic disease, not an isolated wound. The newest entry in a fifteen-year line of evidence putting DFU mortality squarely in the cancer conversation.

$8 Back for Every $1: Earlier Access to #DiabeticFoot Care Is a Bargain #ActAgainstAmputation #CostEffectiveness @alpslimb

A new Queensland study from Son Nghiem, Pete Lazzarini, Lauren Ward and colleagues in Diabetic Medicine finds that investing in earlier access to diabetic foot services returns nearly $8 for every $1 spent — with lower costs, fewer hospitalisations, and better quality of life.

We Moved to the Toe to Escape Calcification — and It Followed Us There: Digital Artery Calcification, Falsely-High Toe Pressures, and a 20–30 mmHg Temporary Fix #DiabeticFoot #PAD #CLTI #ToePressure #Calcification #LimbPreservation #ActAgainstAmputation @alpslimb

We moved to the toe pressure precisely because digital arteries were supposed to be spared from calcification. A new JVS-Vascular Insights study from Welling, Bakker, Ferraresi and colleagues finds digital artery calcification in nearly 30% of limbs, shows it doubles one-year limb-event risk, and that it falsely elevates toe pressure — with a simple fix: when calcium shows on the foot film, subtract 20–30 mmHg.

Hiding in Plain Sight: The #MedicareShoeBill Is Our Most Underused Lifesaver #ActAgainstAmputation @alpslimb

Ninety percent of clinicians know about the Medicare Therapeutic Shoe Benefit and nearly all recommend shoes, yet fewer than one in five eligible patients ever gets them. A new study from Ryan Crews and Carol Kurth shows the bottleneck isn't awareness. It's friction.

What a Sea Cucumber Knows About #WoundHealing That We Don’t: Jobson et al. on Natural #TissueImmortality

Amputated tissue from the sea cucumber Psolus fabricii healed its own wounds and kept living in plain, non-sterile seawater for more than three years. Jobson et al. in Science Advances on "natural tissue immortality" — and why a wound-healing surgeon can't look away.
