Aims: Infrared thermal imaging (IR) is not yet routinely implemented for early detection of diabetic foot ulcers (DFU), despite proven clinical effectiveness. Low-cost, smartphone-based IR-cameras are now available and may lower the threshold for implementation, but the quality of these cameras is unknown. We aim to validate a smartphone-based IR-camera against a high-end IR-camera for diabetic foot assessment.
Methods: We acquired plantar IR images of feet of 32 participants with a current or recently healed DFU with the smartphone-based FLIR-One and the high-end FLIR-SC305. Contralateral temperature differences of the entire plantar foot and nine pre-specified regions were compared for validation. Intra-class correlations coefficient (ICC(3,1)) and Bland-Altman plots were used to test agreement. Clinical validity was assessed by calculating statistical measures of diagnostic performance.
Results: Almost perfect agreement was found for temperature measurements in both the entire plantar foot and the combined pre-specified regions, respectively, with ICC values of 0.987 and 0.981, Bland-Altman plots' mean Δ = -0.14 and Δ = -0.06. Diagnostic accuracy showed 94% and 93% sensitivity, and 86% and 91% specificity.
Conclusions: The smartphone-based IR-camera shows excellent validity for diabetic foot assessment.

Diabetic foot ulcers (DFUs) represents a significant public health issue, with a rising global prevalence and severe potential complications including amputation. Traditional treatments often fall short due to various limitations such as high recurrence rates and extensive resource utilization. This editorial explores the innovative use of acellular fish skin grafts as a transformative approach in DFU management.

Background: Diabetic foot ulcers (DFUs) are a significant contributor to disability and mortality in diabetic patients. Macrophage polarization and functional regulation are promising areas of research and show therapeutic potential in the field of DFU healing. However, the complex mechanism, the difficulty in clinical translation, and the large heterogeneity present significant challenges.

Objective: The out-of-hospital care pathways of people with DFU have been little studied. We used the French National Health Data System (SNDS) to collect refund and care pathway data for all French residents. The aim of this study was to determine the incidence of major lower limb amputation (MA) and associated risk factors in a population with an incident DFU.
