The Use of Best Practice in the Treatment of a Complex Diabetic Foot Ulcer: A Case Report

Diabetic Foot Ulcer Management and Treatment: An Overview of Published Patents

BACKGROUND

One of the most challenging effects of diabetes is diabetic foot ulceration (DFU). DFU may occur in up to one-third of individuals with diabetes mellitus (D.M.) at some point in their lives. The major cause of morbidity in D.M. patients is DFU. The length of treatment is difficult, and DFU recurrence is common.

OBJECTIVE

The most crucial element for the treatment and prevention of DFUs require a multidisciplinary approach. Patients who are at risk should be identified, depending on the type of risk, prophylactic actions etc. It is imperative to identify at-risk patients and take preventative measures accordingly.

METHOD

The at-risk diabetes-related foot ulcer was identified based on the risk category classification, while the foot ulcers were evaluated using Wagner's classification system.

RESULTS

Literature reported that patients with lower limb vascular insufficiency, loss of vibratory sensation, or protective sensation loss have an increased risk of developing foot ulcers. Proper categorization and therapeutic measures will be implemented after the DFU has been formed. The appropriate assessment and management of general health status should include glycemic control, the diagnosis and treatment of vascular disease, standard care for wounds, diagnosis, and infection treatments.

CONCLUSION

The review reflects the updated awareness of the treatment and management of DFU based on the current and past literature and patent analysis.

Knowledge, Awareness, and Practice Related to Diabetic Foot Ulcer Among Healthcare Workers and Diabetic Patients and Their Relatives in Saudi Arabia: A Cross-Sectional Study

Background Diabetes mellitus is a chronic progressive metabolic disorder characterized by high blood sugar affecting the whole body resulting in a significant impact on the quality of life for the patients and their families. Diabetes mellitus complications lead to morbidity, disability, and mortality and represent a serious global health issue threatening the health system worldwide and resulting in a critical economic impact for all countries, especially epidemic ones. Objective The objective of this study was to assess the level of knowledge and awareness regarding diabetic foot and related behaviour among diabetic patients and their relatives, as well as healthcare workers in Saudi Arabia. Methods A cross-sectional analytic study was conducted in 2022 on healthcare workers, diabetic patients, and their relatives above the age of 18 in Saudi Arabia by using a valid, pretested structured questionnaire. The collected data were analyzed using IBM SPSS Statistics for Windows, Version 26 (Released 2019; IBM Corp., Armonk, New York, United States). Results In this study, there was no correlation between the healthcare workers' attitude and knowledge. A total of 131 healthcare workers were involved, and a majority of them had good knowledge regarding the predisposing factors of diabetic foot ulcers, and 63 (48.1%) had good knowledge regarding diabetes foot care. On the other hand, there was poor knowledge regarding the characteristics and complications of diabetes ulcers. This study showed various attitudes among healthcare workers regarding diabetic ulcer care. For example, they prioritized the prevention of ulcers over treatment (N=67, 51.1%), the majority of healthcare workers were very keen to wound care (N=77, 58.8%), and they believed that it was their responsibility to educate their patients about reducing re-ulceration (N=86; 65.7%). However, 52 participants (39.7%) considered management of diabetic foot ulcer time-consuming, 54 (41.2%) mentioned that if they had the opportunity, they would like to avoid taking care of the diabetic wound, and 51 (38.9%) reported non-satisfaction with diabetic wound care.  One hundred diabetic patients and 117 relatives also were involved, and only 41.3% of participants (patients and relatives) had good knowledge regarding diabetes mellitus. However, our findings also revealed that 91.65% of the participants had good knowledge and a favourable attitude towards diabetes mellitus and diabetic foot care. Nevertheless, even though the participants had good knowledge regarding foot care, they had poor practice, with 56.55% scoring poor on the assessment questionnaire.  Conclusion Our study shows that most of the participants had good knowledge and attitudes but poor practices. This highlights the need for more efforts to educate the Saudi population about diabetes and its complications.

A Review of Immunomodulatory Reprogramming by Probiotics in Combating Chronic and Acute Diabetic Foot Ulcers (DFUs)

Diabetic foot ulcers (DFUs) are characterized by a lack of angiogenesis and distal limb diabetic neuropathy. This makes it possible for opportunistic pathogens to protect the biofilm-encased micro-communities, causing a delay in wound healing. The acute and chronic phases of DFU-associated infections are distinguished by the differential expression of innate proinflammatory cytokines and tumor necrosis factors (TNF-α and -β). Efforts are being made to reduce the microbial bioburden of wounds by using therapies such as debridement, hyperbaric oxygen therapy, shock wave therapy, and empirical antibiotic treatment. However, the constant evolution of pathogens limits the effectiveness of these therapies. In the wound-healing process, continuous homeostasis and remodeling processes by commensal microbes undoubtedly provide a protective barrier against diverse pathogens. Among commensal microbes, probiotics are beneficial microbes that should be administered orally or topically to regulate gut-skin interaction and to activate inflammation and proinflammatory cytokine production. The goal of this review is to bridge the gap between the role of probiotics in managing the innate immune response and the function of proinflammatory mediators in diabetic wound healing. We also highlight probiotic encapsulation or nanoformulations with prebiotics and extracellular vesicles (EVs) as innovative ways to tackle target DFUs.

Comparing a non-removable total contact cast with a non-removable softcast in diabetic foot ulcers: A retrospective study of a prospective database

OBJECTIVE

Diabetic foot ulcers (DFUs) are mostly cured by an off-loading cast. Healing ratios of a non-removable Total Contact Softcast (TCS) were compared to a conventional Total Contact Cast (TCC), the latter reporting negative effects on lifestyle and transportation.

METHODS

Analysis of prospectively collected data for 2010-2017. Included were patients with a neuropathic DFU. Ischemic ulcers were excluded, as were Charcot arthropathy, non-plantar/non-forefoot ulcer location, and compliance issues. Patients with TCS were compared to TCC. Primary and secondary outcomes were healing ratio and healing time of DFU.

RESULTS

50 patients with 61 cast periods were included. Mean age was 63.7 ± 10.1 years. Overall successful ulcer healing was 71% (43/61). Except for depth of the DFUs, between-group patient characteristics were comparable; deeper DFUs were reported in the TCC group. This group reported 65% healed DFU (22/34), the TCS group 74% (20/27). Mean healing time was 8.4 weeks (95 %CI 5.9-10.8) for TCC and 5.5 weeks (95 %CI 4.2-6.9) for TCS (p = 0.052). Depth of the wound was a confounder.

CONCLUSIONS

TCS had a similar DFU healing ratio and a potentially clinically relevant effect (HR 1.47, 95 %CI 0.64-3.38) on healing time (ns). Ulcer depth is important for time to ulcer healing. A randomized study is recommended.

Design

This was a qualitative study. Data gathered from in-depth interviews with 22 clinicians were coded into themes and analyzed.

Participants

Participants included hospital-based clinicians: four clinical specialists, eight emergency nurses, four emergency doctors, three general practitioners, and three clinical administrators.

Setting

The study was conducted in university-affiliated hospitals.

Results

All clinicians who were invited to participate believed that the use of telemedicine in first aid was promising and effective. Participants stated that relevant technology should be designed to synergize the chain of existing platforms in the industry and that it should be determined who has the authority to utilize such technology and how it should be used to achieve the sought-after benefits. The use of such technology refreshes the role of clinicians and their relationship with patients. Additionally, participants believed that the government could play an important role especially in the reform of medical systems.

Conclusion

Telemedicine can facilitate the provision of conventional first aid and systematically exploit existing resources due to its feasibility and effectiveness. The social benefits of using tele-first-aid in clinical and community applications, especially when used in coordination with existing resources, make its adoption an inevitable trend in the field.

Current Therapeutic Strategies in Diabetic Foot Ulcers

Diabetic foot ulcers (DFUs) are the fastest growing chronic complication of diabetes mellitus, with more than 400 million people diagnosed globally, and the condition is responsible for lower extremity amputation in 85% of people affected, leading to high-cost hospital care and increased mortality risk. Neuropathy and peripheral arterial disease trigger deformities or trauma, and aggravating factors such as infection and edema are the etiological factors for the development of DFUs. DFUs require identifying the etiology and assessing the co-morbidities to provide the correct therapeutic approach, essential to reducing lower-extremity amputation risk. This review focuses on the current treatment strategies for DFUs with a special emphasis on tissue engineering techniques and regenerative medicine that collectively target all components of chronic wound pathology.
