Evaluating the effects of sedentary behaviour on plantar skin health in people with diabetes

Great work from Fran Henshaw and coworkers Evaluating the effects of sedentary behaviour on plantar skin health in people with diabetes Background: Diabetes-Related Foot Ulcers (DRFUs) are a common and devastating consequence of Diabetes Mellitus and are associated with high morbidity, mortality, social and economic costs. Whilst peak plantar pressures during gait are implicated cited […]

A Systematic Review and Narrative Synthesis of Risk Prediction Tools Used to Estimate Mortality, Morbidity, and Other Outcomes Following Major Lower Limb Amputation

A systematic review on key instruments that can be used preoperatively to predict postoperative morbidity from our Welsh colleagues. Perhaps something like this, combined with WIFI+Function could be useful in preoperative prediction. Objective The decision to undertake a major lower limb amputation can be complex. This review evaluates the performance of risk prediction tools in […]

Biomechanical modelling of diabetic foot ulcers: A computational study

Yet another intriguing “virtual diabetic foot” project. This, from our colleagues at AIIMS in Delhi Diabetic foot problems are widespread globally, resulting in substantial medical, economic, and social challenges for patients and their families. Among diabetic complications, foot ulceration is the most frequent outcome and is more probable to be of neuropathic origin. To date, a plethora of studies […]

Barriers to Prevention and Timely Presentation of Diabetic Foot Ulcers: Perspectives of Patients from a High-risk Urban Population in the United States

Barriers to Prevention and Timely Presentation of Diabetic Foot Ulcers: Perspectives of Patients from a High-risk Urban Population in the United States This from our long time SALSAmigos, Loretta Vileikyte, Jeff Gonzalez and coworkers Abstract: Diabetic foot amputation is a preventable complication that is increasing in incidence in the United States, with disparities across geography, […]

LA County Productivity and Quality Commission (PQC) recognizes @USC/ Rancho / Hot Foot Line Limb Preservation Program “Time is Tissue” @LACountyBOS @RanchoRehab @LACUSCMedCenter #ActAgainstAmputation @SoCalCTSI @USC_Vascular

LA County’s Productivity and Quality Commission announced its 34th Annual Productivity and Quality Awards. Rancho Los Amigos, in concert with USC and LAC+USC were acknowledged for their efforts in limb preservation in people with diabetes. The program, which established a “Hot Foot Line” and associated limb preservation service dramatically reduced high-level amputation while also cutting […]

The Thermo-Pressure Concept: A New Model in Diabetic Foot Risk Stratification

The Thermo-Pressure Concept: A New Model in Diabetic Foot Risk Stratification This from our Maltese SALSAmigos, Perren and coworkers Abstract: Elevated foot pressure and high temperatures have been proposed as predictive factors for diabetic foot ulceration; however, on their own, their predictive value is still questionable. This pilot study hypothesized that combining these two measurements […]

Validity and Reliability of a Vibration-Based Cell Phone in Detecting Peripheral Neuropathy among Patients with a Risk of Diabetic Foot Ulcer

After describing this concept some years ago, we’re so happy to see this kind of idea finally be validated! Congratulations to Jasmin and coworkers for this effort that might help bring semi-quantitative nerve testing out into the community. The aim of this study was to determine the validity and reliability of a vibration-based cell phone […]

The microbiology of diabetic foot infections: a meta-analysis

The microbiology of diabetic foot infections: a meta-analysisExcellent work from MacDonald and coworkers from Edinburgh. The microbiology of diabetic foot infections: a meta-analysis Background: Diabetic foot ulcers are a common complication of poorly controlled diabetes and often become infected, termed diabetic foot infection. There have been numerous studies of the microbiology of diabetic foot infec- […]

Measuring progress to healing: A challenge and an opportunity – The value of wound margin advancement

Great, provocative work by our colleagues Prof. Keith Harding and coworkers. Complete healing is problematic as an endpoint for evaluating interventions for wound healing. The great heterogeneity of wounds makes it difficult to match groups, and this is only possible with multivariate stratification and/or very large numbers of subjects. The substantial time taken for wounds […]
