Although diabetes takes a costly toll, literally and figuratively, on the foot and ankle, there is a stunning gap in lower extremity diabetes research funding.1 Our recent study, published in Diabetes Care, examined U.S. National Institutes of Health funding for diabetes and diabetic foot ulcers. Our research revealed total spending of $7.1 billion in funding for overall diabetes research from 2002 to 2011 with only $11.8 million, or 0.17 percent, reserved for research on diabetic foot ulcers. As we note in the study, this is a 604-fold disparity. Read More.

A recent study published in the European Journal of Vascular and Endovascular Surgery shows that without revascularization, a significant number of patients with severe peripheral arterial disease will die before their diabetic foot ulcers heal.1 Read More.

Podiatric physicians can face a dilemma of whether patients with diabetic peripheral neuropathy can exercise due to insensitive feet. A recent study in The Foot says neuropathic patients can participate in some monitored exercise.1 Read More.

When Offloading Devices Are Harder To Remove, Are Wounds Easier To Heal?

Here's an intriguing meta-analysis from a team in Adelaide in South Australia. In a recently published study in Diabetes/Metabolism Research and Reviews, Morona and colleagues compared different offloading devices for neuropathic foot ulcers in patients with diabetes.1 The researchers searched medical bibliographic databases, the Internet and reference lists from January 1966 to May 2012. They focused on systematic reviews and controlled studies comparing the use of different offloading devices. Read More.

Should We Revisit Accepted Endpoints In The Studies Of Modalities For Wound Healing?

Despite the high cost and potentially grave complications of chronic cutaneous ulcers, the Food and Drug Administration (FDA) has not approved a new drug therapy for such ulcers in over a decade. Indeed, the mortality rate of chronic ulcers can eclipse that of many cancers. This begs the question: Should we apply the endpoints researchers use for drugs in cancer studies in a similar fashion to studies of modalities for chronic cutaneous ulcers? Read More.

Emphasizing a Proactive Multidisciplinary Approach To The Combination Of Neuropathic Ulcers And Peripheral Arterial Disease

Joe Mills, MD, and I, along with many of our colleagues, have been struck with how our population has changed but our methods (and language) have not. We discussed this previously in a dendrogram (cluster analysis) from a study I co-authored with Lavery and Peters in 2008. (see http://www.ncbi.nlm.nih.gov/pubmed/18593392 ). Read More.

We are pleased to announce the formation of the Interdisciplinary Consortium on Advanced Motion Performance (iCAMP) at the University of Arizona. This consortium will be lead by Bijan Najafi, PhD, a biomedical engineer and renowned expert on human motion. Comprised of teams from podiatric and vascular surgery, orthopedics, nursing, geriatrics, anthropology and engineering, iCAMP researchers will be studying physical activity patterns, gait parameters and three-dimensional joint structures through high-tech sensors that are embedded in shirts, socks, straps and patches worn by patients.

Recently, the use of NPWT has expanded beyond the treatment of diabetic foot ulcers. Negative pressure wound therapy improves the take of split-thickness skin grafts by acting as a bolster and preventing an accumulation of fluid beneath the graft site.1 In 2004, Moisidis and co-workers found that the quality of take for split-thickness skin grafts subjected to NPWT was qualitatively improved in 50 percent of the cases they studied.2 Read More.
