Diagnostic Tools to Establish the Presence and Severity of Peripheral Arterial Disease in People...
Diabetic FootPeripheral Arterial Disease5 moreIn the UK there are over 7,000 leg amputations each year because of diabetes. The most important cause of this is poor circulation. The detection of poor circulation in patients with diabetes is difficult. A number of tests exist to detect poor circulation (known as peripheral arterial disease (PAD)). However, there is confusion as to which is the gold standard. The DM PAD study aims to determine the diagnostic performance of index tests (audible handheld Doppler, visual handheld Doppler, ankle brachial pressure index (ABPI), exercise ABPI and toe brachial pressure index (TBPI)) for the diagnosis of PAD in patients with diabetes as determined by a reference test (CTA or MRA).
Safety Evaluation of the DiaSole Insole With Diabetic Foot Ulcers.
Diabetes Mellitus Foot UlcerOffloading plays an important part Diabetic foot ulcers healing. The modular design of the DiaSole would allow the offloading cavity to be changed in line with the changing ulcer dimensions. It may be possible to use the DiaSole for other causes of neuropathic foot ulcerations (such as rheumatoid arthritis), but the safety of the insole needs assessing first. There is already evidence to support the use of offloading insoles in the healing and prevention of pressure ulcers, DiaSole may be an improved insole for this purpose.
In-shoe Pressures Associated With Footwear Fit Guidelines
Diabetic Foot UlcerDiabetic NeuropathiesOne in five foot ulcers are caused by the footwear worn by people with diabetes, yet there is a lack of consensus around footwear fit. Recommended toe gaps (the gap between the longest toe and the inside of the shoe) vary depending on the footwear guidance referred to but no research to date has assessed the recommendations' effectiveness in minimising in-shoe pressures. The investigators will carry out a pilot study in 60 people with diabetes and loss of foot sensation (neuropathy). In this study, the investigators will measure in-shoe pressures whilst participants walk at the same pace to the beat of a metronome. An insole placed inside participants' shoes will measure in-shoe pressures. Participants will wear the same (standardised) type of footwear. The study is designed to detect a difference in pressure within this made-to-measure footwear whose fit conforms to Standard 1 guidance compared with footwear whose fit conforms to Standard 2 guidance. Differences between Standards 1 and 2 with Standard 3 will be considered secondary analyses. Standards are simplified to three non-overlapping recommended toe gap ranges of 0.5-1.0cm; 1.5-2.0cm and 1.0-1.5cm. The investigators will also analyse the heat images taken with a thermographic camera before and after walking in standardised footwear whose fit confirms to these standards (this is known as the plantar thermal stress response to walking). Footwear fit will be determined by measuring the dimensions of participants' feet and that of participants' footwear and comparing the two. The investigators will also measure footwear fit and associated in-shoe pressure/plantar thermal stress response in participants' habitual footwear during walking at paced and self-selected speeds.
Bacteriophage Therapy TP-102 in Patients With Diabetic Foot Infection
Diabetic Foot InfectionTP-102 is a novel bacteriophage cocktail comprised of 5 (five) lytic bacteriophages against Staphylococcus aureus, Pseudomonas aeruginosa, and Acinetobacter baumannii. TP-102 is being developed for topical treatment of patients with wound infections including chronic ulcers; applied every other day (three times weekly (TIW)).

Diabetes MellitusThis study will be conducted to investigate the effect of Insulin iontophoresis mixed with oleic acid versus topical insulin in patients with chronic diabetic foot ulcer
Nocardia Cell Wall Skeleton for the Treatment of Diabetic Foot Ulcer Wounds
Diabetic Foot UlcerTherapy1 moreThis study was to investigate the efficacy and safety of Nocardia rubra Cell Wall Skeleton (NCWS) in the treatment of diabetic foot ulcer wounds. The study was a prospective, randomized, controlled, multicentre study . The subjects were randomly divided into two groups: NCWS group and control group(silver ions dressing), with a total of 116 cases and 58 cases in each group. Patients in the NCWS group received nocardia rubra cell wall skeleton for external use, in parallel with silver ions dressing treatment. The efficacy and side effects were observed, with a primary endpoint of 30-days wound healing rate.
CGM and DFU Healing Post-discharge
Diabetic FootDiabetes Type 2 With Diabetic Ulcer of Toe1 moreThe purpose of this study is to look at the benefits of using a Continuous Glucose Monitoring (CGM) system compared with standard-of-care testing for patients with diabetes type 2 and diabetic foot ulcers (DFU) and how this will improve wound healing. The CGM system allows medical staff and patients with diabetes to monitor and make treatment decisions to improve glucose control, without the need for performing fingersticks. Hence, the use of CGM will decrease the painful and burdensome task of performing finger sticks several times per day and may prevent low blood glucose in patients with diabetes.
Examining the Effectiveness of DermGEN™ in the Treatment of Diabetic Foot Ulcers in First Nations...
Diabetes MellitusUlcer Foot6 moreThe study will examine the effectiveness of a decellularized dermal matrix (i.e., DermGEN™) in improving wound healing, quality of life and associated costs of treatment of DFUs in First Nations people living in the Northwestern Ontario Communities. First Nations people with active diabetic foot (DFU) ulcer attending a wound care clinic located at the Rainy River district office. An interventional, two-arm, randomized, prospective study of (1) standard of care (control) vs. (2) DermGEN™ - a decellularized dermal matrix (treatment) will be used in the treatment and management of DFU. Patients will be randomized to each arm (n=60 per arm) based on power calculations using data from our Pilot study.
Peer Support for Patients With Diabetic Foot Ulcers
Diabetic Foot UlcerDiabetic Wound5 moreThe objective of the study is to develop a peer support program that helps improve ulcer care in patients with a diabetic foot ulcer (DFU).Diabetes, peripheral arterial disease (PAD), foot ulceration, and subsequent amputation are unevenly patterned in terms of racial/ethnicity, socioeconomic status, health insurance, and geographic area. The project will identify opportunities to reduce health disparities among economically marginalized patients regarding DFU outcomes.
Assessment of the Efficacy and Tolerance of Sub-cutaneous Re-injection of Autologous Adipose-derived...
Diabetic Foot UlcerDiabetic foot ulcer (DFU) is a major complication and the leading cause of hospitalization among people with diabetes mellitus. It occurs in 15% of all patients with diabetes and precedes 84% of all lower leg amputations. Despite many therapeutic advances over the past decades, including dressings (hydrocolloids, alginate, skin substitutes) and growth factors, healing rates of DFU remain low. Mechanisms of faulty wound healing in diabetic patients are complex, related to both intrinsic and extrinsic factors. The main reasons for impaired healing appears to be: 1/exhaustion of local cell populations that promote wound healing; 2/excessive production of matrix metalloproteases (MMPs) coupled with reduced expression of the tissue inhibitors of MMPs; 3/impaired neovascularisation coupled with reduced numbers of endothelial progenitor cells and impairment of their functioning. These imbalances may result in excessive degradation of extracellular matrix components, as well as an inappropriate local inflammatory response . Adipose-derived stroma vascular fraction provides a rich and easily accessible source of autologous cells for regenerative medicine applications. Il contains multipotent stem cells and progenitors called adipose-derived regenerative cells (ADRCs) able to stimulate wound healing. There are attracted to the wound site where they supplement the wound bed with similar cell types, secrete numerous growth factors and cytokines, increase macrophage recruitment, enhance granulation tissue, and improve vascularisation . The reparative capabilities coupled with good safety of ADRCs have been illustrated in a study for treating severe and irreversible radiation-induced lesions, and in a study for treating sclerodactyly in patients with diffuse scleroderma. Numerous case reports showing healing of refractory wounds following treatment with autologous ADRCs have also been reported. Based on these previous reports, the present study aims to assess the efficacy and tolerance of injection of ADRCs for the local treatment of neuropathic or neuro-ischemic DFU.
