Innovative Nanocomposites for Drug Delivery: A Novel Approach for Diabetic Foot Ulcer.

Diabetic Foot Ulcer (DFU) is a chronic wound, and a person with diabetes has an increased lifetime risk of foot ulcers (19%-34%) and high morbidity (65% recurrence in 3-5 years, 20% lifetime amputation). Recent data have shown rising amputation rates, especially in the younger and minority populations. This abstract discusses innovative approaches for addressing this issue. This highlights the use of nanotechnology-based drug nanocomposite systems for natural wound healing therapies, with a focus on nanoparticles, nano-emulsions, and nanogels. This review also emphasizes the potential of hydrogels for drug delivery, highlighting their versatility in various medical applications. Furthermore, it delves into the use of silver nanoparticles (AgNP's) for treating diabetic wounds while acknowledging the need to address potential toxicity concerns. Finally, the abstract discusses the utilization of traditional herbal medicine and the integration of modern science to advance wound care, particularly focusing on wound microbiome, immune response, and controlled herbal medicine delivery. This study also highlights clinical trials conducted on DFU. Overall, these abstracts highlight the importance of exploring diverse and innovative solutions to chronic wound management.

Remote Foot Temperature Monitoring Among Veterans: Large Observational Study of Noncompliance and Its Correlates.

In-home remote foot temperature monitoring (RTM) holds promise as a method to reduce foot ulceration in high-risk patients with diabetes. Few studies have evaluated adherence to this method or evaluated the factors associated with noncompliance. The aims of this study were to estimate noncompliance in patients who were enrolled in RTM nationwide across Department of Veterans Affairs (VA) and to evaluate characteristics associated with noncompliance. We conducted an observational study including 1137 patients in the VA who were enrolled in RTM between January 2019 and June 2021, with follow-up through October 2021. Patient information was obtained from the VA's electronic health record and RTM use was obtained from the company. Noncompliance was defined as using the mat <2 days per week for ≥4 of the 12 months of follow-up. Using a multivariable model, we calculated odds ratios (ORs) and 95% CIs for associations between various factors and noncompliance and compared using Akaike information criterion statistics, a measure of model fit. The sample was predominantly male (n=1125, 98.94%) ; 21.1% (n=230) were Black and 75.7% (n=825) were White. Overall, 37.6% (428/1137) of patients were classified as noncompliant. In the multivariable model, an intermediate area deprivation index was statistically significantly and inversely associated with noncompliance (area deprivation index 50-74 vs 1-24; OR 0.56, 95% CI 0.35-0.89); factors significantly and positively associated with noncompliance included recent history of osteomyelitis (OR 1.44, 95% CI 1.06-1.97), Gagne comorbidity index score ≥4 (vs ≤0; OR 1.81, 95% CI 1.15-2.83), telehealth encounters (28+ vs <6; OR 1.70, 95% CI 1.02-2.84), hemoglobin A1c≥10 (vs <5.7; OR 2.67, 95% CI 1.27-5.58), and current smoking (OR 2.06, 95% CI 1.32-3.20). Based on Akaike information criterion differences, the strongest factors associated with noncompliance were behavioral factors (poor glucose control [as measured by hemoglobin A1c] and smoking), and to a lesser extent, factors such as a recent history of osteomyelitis and an elevated Gagne comorbidity index, indicating a high comorbidity burden. To reduce the risk of ulcer recurrence and amputation, proactively providing additional support for self-monitoring to patients with characteristics identified in this study (poor glucose control, current smoking, high comorbidity burden) may be helpful. Furthermore, research is needed to better understand barriers to use, and whether the addition of design features, reminders, or incentives may reduce noncompliance and the risk of foot ulcers.

The Effect of Dimple Insole Design on the Plantar Temperature and Pressure in People with Diabetes and in Healthy Individuals.

An increase in plantar pressure and skin temperature is commonly associated with an increased risk of diabetic foot ulcers. However, the effect of insoles in reducing plantar temperature has not been commonly studied. The aim was to assess the effect of walking in insoles with different features on plantar temperature. Twenty-six (F/M:18/8) participants-13 with diabetes and 13 healthy, aged 55.67 ± 9.58 years-participated in this study. Skin temperature at seven plantar regions was measured using a thermal camera and reported as the difference between the temperature after walking with an insole for 20 m versus the baseline temperature. The mixed analyses of variance indicated substantial main effects for the Insole Condition, for both the right [Wilks' Lambda = 0.790, F(14, 492) = 4.393, p < 0.01, partial eta squared = 0.111] and left feet [Wilks' Lambda = 0.890, F(14, 492) = 2.103, p < 0.011, partial eta squared = 0.056]. The 2.5 mm-tall dimple insole was shown to be significantly more effective at reducing the temperature in the hallux and third met head regions compared to the 4 mm-tall dimple insole. The insoles showed to be significantly more effective in the diabetes group versus the healthy group, with large effect size for the right [Wilks' Lambda = 0.662, F(14, 492) = 8.037, p < 0.000, Partial eta-squared = 0.186] and left feet [Wilks' Lambda = 0.739, F(14, 492) = 5.727, p < 0.000, Partial eta-squared = 0.140]. This can have important practical implications for designing insoles with a view to decrease foot complications in people with diabetes.

Pressure-Relieving Effect of Different Insole Top Covers in People with Diabetes at High Risk of Foot Ulceration.

Pressure-relieving footwear helps prevent foot ulcers in people with diabetes. The footwear design contributes to this effect and includes the insole top cover. We aimed to assess the offloading effect of materials commonly used as insole top cover. We measured 20 participants with diabetes and peripheral neuropathy for in-shoe peak pressures while walking in their prescribed footwear with the insole covered with eight different materials, tested in randomized order. Top covers were a 3 mm or 6 mm thick open or closed-cell foam or a 6 mm thick combination of open- and closed-cell foams. We re-assessed pressures after one month of using the top cover. Peak pressures were assessed per anatomical foot region and a region of interest (i.e., previous ulceration or high barefoot pressure). Walking comfort was assessed using a 10-point Likert scale. Mean peak pressure at the region of interest varied between 167 (SD:56) and 186 (SD:65) kPa across top covers (p < 0.001) and was significantly higher for the 3 mm thick PPT than for four of the seven 6 mm thick top covers. Across 6 mm thick top covers, only two showed a significant peak pressure difference between them. Over time, peak pressures changed non-significantly from -2.7 to +47.8 kPa across top cover conditions. Comfort ratings were 8.0 to 8.4 across top covers (p = 0.863). The 6 mm thick foams provided more pressure relief than the 3 mm thick foam during walking in high-risk people with diabetes. Between the 6 mm thick foams and over time, only small differences exist. The choice of which 6 mm thick insole top cover to use may be determined more by availability, durability, ease of use, costs, or hygienic properties than by superiority in pressure-relief capacity.

Effect of different inner pressures of air insoles and walking durations on plantar pressure time integral

Air insoles have provided insights for reducing the risk of diabetic foot ulcers (DFU). The pressure time integral (PTI) is an effective assessment that considers the time effect in various physical activities. We investigated the interactions between three different insole inner pressures (80, 160, and 240 mmHg) and two walking durations (10 and 20 min). The big toe (T1), first metatarsal head (M1), and second metatarsal head (M2) were investigated in 13 healthy participants. One-way analysis of variance (ANOVA) showed that the effects of each insole inner pressure significantly differed (P < 0.05) with a 10 min walking duration. The PTI values resulting from 80 mmHg in M2 (38.4 ± 3.8, P = 0.002) and 160 mmHg in M1 (44.3 ± 4.3, P = 0.027) were lower than those from 240 mmHg. Additionally, the paired t test showed that the effects of each walking duration were also considerably different at 160 mmHg. The PTI at 10 min was lower than that at 20 min in M1 (44.31 ± 4.31, P = 0.015) and M2 (47.14 ± 5.27, P = 0.047). Thus, we suggest that walking with a pressure of 160 mmHg for 10 min has a lower risk of DFU.

Detection of Risk for Foot Ulceration and its Relation to Foot Self-care among Diabetic Elderly Patients

Detection of Risk for Foot Ulceration and its Relation to Foot Self-care among Diabetic Elderly Patients

Incretin-based therapy and the risk of diabetic foot ulcers and related events.

To investigate the effect of dipeptidyl peptidase-4 inhibitors (DPP4-Is) and glucagon-like peptide-1 receptor agonists (GLP1-RAs) on diabetic foot ulcer (DFU) and DFU-related outcomes (lower limb amputation [LLA], DFU-related hospitalization and mortality). We performed a cohort study with data from the Clinical Practice Research Datalink Aurum database with linkage to hospital data. We included people with type 2 diabetes starting treatment with metformin. Then we propensity score matched new users of DPP4-Is and sulphonylureas (N = 98 770), and new users of GLP1-RAs and insulin (N = 25 422). Cox proportional hazards models estimated the hazard ratios (HRs) for the outcomes. We observed a lower risk of DFU with both DPP4-I use versus sulphonylurea use (HR 0.88, 95% confidence interval [CI]: 0.79-0.97) and GLP1-RA use versus insulin use (HR 0.44, 95% CI: 0.32-0.60) for short-term exposure (≤ 400 days) and HR 0.74 (95% CI: 0.60-0.92) for long-term exposure (>400 days). Furthermore, the risks of hospitalization and mortality were lower with both DPP4-I use and GLP1-RA use. The risk of LLA was lower with GLP1-RA use. The results remained consistent across several sensitivity analyses. Incretin-based therapy was associated with a lower risk of DFU and DFU-related outcomes. This suggests benefits for the use of this treatment in people at risk of DFU.

Patient with Diabetic Foot Ulcer Admitted in Surgery Ward; Risk Factors, Associations and Grades of Presentation

Background: The management of chronic diabetic foot ulcers (DFU) poses a great challenge to the treating physician and surgeon. The aim of this study was to identify the risk factors, clinical presentation, and outcomes associated with chronic DFU. Objective: To determine the various risk factors for diabetic foot ulcers and study their associations. To study the grades of diabetic foot ulcers at presentation. Method: Purposive sampling. This study was done in the Surgery department of Shaheed Ziaur Rahman Medical College Hospital (SZMCH), Bogura for period of twelve (12) months. 100 cases were selected after informed consent. Study group (A) comprises of 50 cases of type 2 diabetes with diabetic foot ulcer and control group (B) comprises of 50 cases of age and gender matched type 2 diabetics without foot ulcers. Patients having serious systemic illness, type I diabetics and non-diabetic patients presenting with foot ulcer were excluded. Age, gender, duration of diabetes, duration of ulcer, glycemic control, presence of neuropathy and vascular disease were documented. Grading and Staging of ulcer was done according to New University of Texas Diabetic Wound Classification. Various risk factors were compared between the two groups. Data analyzed via SPSS version 17 with significant p-value &lt; 0.05. Results: Among 100 cases (64 % males &amp; 36 % females); mean age was 58.50 ± 9.8 (group A) versus 50.40 ± 10.5 (group B). Mean duration of diabetes was longer in group A (10.49 ± 7.06 years) vs. group B (8.34 ± 4.83 years) (p = 0.019). Glycemic control was poor in group A (72 %) vs. group B (56 %) (p = 0.045). There was significantly more peripheral vascular disease in group A (50 %) vs. group B (32 %) (p= 0.005). Sensory neuropathy was more in group A (90 %) vs. group B (38 %) (p &lt; 0.0001). Grade-I ulcer was present in 16 % cases, Grade-II in 38 % and Grade-III in 46 %. Conclusion: Neuropathy carries highest risk for diabetic foot ulcer, followed by peripheral vascular disease and poor glycemic control. Therefore, diabetic patient must be educated about these risk factors, foot care and self-examination and to have regular screening by clinician. Appropriate glycemic control and timely medical and surgical intervention may reduce morbidity in diabetics.

Denosumab, for osteoporosis, reduces the incidence of type 2 diabetes, risk of foot ulceration and all-cause mortality in adults, compared with bisphosphonates: An analysis of real-world, cohort data, with a systematic review and meta-analysis.

To evaluate the impact of denosumab on (i) the incidence of type 2 diabetes (T2D), and (ii) long-term health outcomes (microvascular [neuropathy, retinopathy, nephropathy] and macrovascular [cardiovascular disease, cerebrovascular accident] complications, and all-cause mortality) in patients with T2D, before (iii) combining results with prior studies using meta-analysis. A retrospective analysis of data in a large global federated database (TriNetX; Cambridge, MA) was conducted from 331 375 patients, without baseline T2D or cancer, prescribed either denosumab (treatment, n = 45 854) or bisphosphonates (control, n = 285 521), across 83 healthcare organizations. Propensity score matching (1:1) of confounders was undertaken that resulted in 45 851 in each cohort. Secondary analysis further evaluated the impact of denosumab on long-term health outcomes in patients with T2D. Additionally, we systematically searched prior literature that assessed the association between denosumab and T2D. Estimates were pooled using random-effects meta-analysis. Risk of bias and evidence quality were assessed using Cochrane-endorsed tools. Denosumab (vs. bisphosphonates) was associated with a lower risk of incident T2D over 5 years (hazard ratio 0.83 [95% confidence interval {CI} 0.78-0.88]). Secondary analysis showed significant risk reduction in all-cause mortality (0.79 [0.72-0.87]) and foot ulceration (0.67 [0.53-0.86]). Also, pooled results from four studies (three observational, one randomized controlled trial) following meta-analysis showed a reduced relative risk (RR [95% CI]) for incident T2D in patients prescribed denosumab (0.83 [0.79-0.87]) (I2 = 10.76%). This is the largest cohort study to show that denosumab treatment is associated with a reduced RR of incident T2D, as well as an associated reduced RR of all-cause mortality and microvascular complications, findings that may influence guideline development in the treatment of osteoporosis, particularly in patients who are at a high risk of T2D.

Pressure-Reducing Design of 3D-Printed Diabetic Shoe Midsole Utilizing Auxetic Lattice Structure

With the global rise in the prevalence of diabetes, diabetic patients need innovative footwear designs to reduce the risk of foot ulcers. This study examined the mechanical properties of diabetic shoe midsoles featuring auxetic lattice structures. Through the construction of finite element models and simulation, this research compared the biomechanical parameter differences in the plantar regions of the metatarsal head, midfoot, and hindfoot when wearing two types of auxetic midsoles with internal angles of 60° and 75° and a non-auxetic midsole with an internal angle of 90° under both walking and running conditions. Compared to the non-auxetic midsole, the auxetic midsoles significantly reduced the peak plantar pressure and optimized the pressure distribution across various plantar regions. Notably, the auxetic 60° midsole reduced the peak plantar pressure by 19.68–55.25% and 16.19–54.39% compared to the non-auxetic 90° midsole during walking and running, respectively. This study also verified that the auxetic midsoles exhibited greater adaptability and compliance to the plantar foot shape, contributing to reductions in plantar pressure in comparisons of deformation values and plantar contact areas across the different midsoles. Auxetic midsoles manufactured using 3D printing technology have significant potential to prevent diabetic foot ulcers and maintain human foot health. This research integrates insights and techniques from materials science and ergonomics, offering a new direction for footwear design.

Personalized prediction of diabetic foot ulcer recurrence in elderly individuals using machine learning paradigms.

This study utilizes machine learning to analyze the recurrence risk of diabetic foot ulcers (DFUs) in elderly diabetic patients, aiming to enhance prevention and intervention efforts. The goal is to construct accurate predictive models for assessing the recurrence risk of DFUs based on high-risk factors, such as age, blood sugar control, alcohol consumption, and smoking, in elderly diabetic patients. Data from 138 elderly diabetic patients were collected, and after data cleaning, outlier screening, and feature integration, machine learning models were constructed. Support Vector Machine (SVM) was employed, achieving an accuracy rate of 93%. Experimental results demonstrate the effectiveness of SVM in predicting the recurrence risk of DFUs in elderly diabetic patients, providing clinicians with a more accurate tool for assessment. The study highlights the significance of machine learning in managing foot ulcers in elderly diabetic patients, particularly in predicting recurrence risk. This approach facilitates timely intervention, reducing the likelihood of patient recurrence, and introduces computer-assisted medical strategies in elderly diabetes management.

Exploring the influence of dietary habits on foot risk in type 2 diabetes patients: An observational study

Background & AimTo date, there are no studies demonstrating the impact of the Mediterranean diet on the risk of diabetic foot ulcer. The aim of this research was to examine the connection between adherence to the Mediterranean diet and the level of risk of diabetic foot ulcers in individuals with type 2 diabetes. MethodsObservational pilot study collecting sociodemographic, anthropometric, lifestyle, and type 2 diabetes-related data. Loss of protective sensation was assessed using the Semmes Weinstein 5.07-10g monofilament, considered altered when not perceived in four points. Vascular status was assessed by palpating pulses and ankle-brachial index, indicating peripheral arterial disease if ankle-brachial index was less than 0.9 or if both pulses were absent. Foot deformities were recorded. The risk of diabetic foot ulcers was stratified into two categories: no risk and risk of diabetic foot ulcers. Adherence to the Mediterranean diet was evaluated using the Mediterranean Diet Adherence Screener-14 questionnaire (good adherence with score > 7). ResultsOf the 174 patients with type 2 diabetes mellitus who participated (61.5% men and 38.5% women) with a mean age of 69.56 ± 8.86 years and a mean duration of type 2 diabetes of 15.34 ± 9.83 years. Non-adherent patients to the Mediterranean diet exhibited a higher association of diabetic foot ulcers (p=0.030) and a lower average score on the Mediterranean Diet Adherence Screener-14 (p=0.011). Additionally, a lower incidence of diabetic foot ulcers was observed in those who consumed nuts three or more times a week (p=0.003) and sautéed foods two or more times a week (p=0.003). Multivariate analysis highlighted the importance of physical activity (OR=0.25, 95% CI 0.11-0.54; p<0.001), podiatric treatment (OR=2.59, 95% CI 1.21-5.56; p=0.014), and duration of type 2 diabetes (OR=3.25, 95% CI 1.76-5.99; p<0.001) as significantly associated factors related to the risk of diabetic foot ulcers. ConclusionsAdhering to the Mediterranean diet correlates with a lower incidence of diabetic foot ulcers in individuals diagnosed with type 2 diabetes mellitus. Furthermore, factors such as regular physical activity, podiatric treatment, and the duration of type 2 diabetes mellitus emerge as pivotal in preventing diabetic foot ulcers.

The association between tobacco smoking and systolic toe pressures in active foot ulceration

Smoking may increase the risk of diabetic foot disease and ulceration. It does so by impairing glycaemic control and promoting the formation of advanced glycated end-products. Additionally, smoking is known to delay surgical wound healing and accelerate peripheral arterial disease. We aimed to determine whether toe pressures differed in smokers with a foot ulcer, when compared to non-smokers and ex-smokers, as well as ulcer outcomes at 12 months, among patients attending Blacktown Hospital High Risk Foot Service (HRFS). This study is a retrospective analysis of our prospectively collected clinic database. Eligible participants were adults attending the HRFS between June 2020 and April 2022. Participants were included if they had an ulcer, at least one systolic toe pressure reading completed at their initial visit and attended at least one follow-up visit. Participants were followed until healing, loss to follow-up or a minimum of 12 months. A total of 195 participants were included; 36 smokers, 82 ex-smokers, and 77 controls who had never smoked. Smoking status was by self-report. Current smokers were significantly younger at initial presentation (p = .002) and tended towards lower socioeconomic status (p = .067). Current smokers were significantly more likely to have ischaemic grade 3 toe pressures (< 30 mmHg) of their left foot (p = .027), suggestive of reduced perfusion. At the end of follow up period, smokers had the numerically highest rates of minor amputations. In conclusion, smokers ulcerate younger and are more likely to have grade 3 ischaemia. Collecting information about the brachial artery pressures and the time since the last cigarette may clarify any relationship between smoking and toe pressures.Trial registration: WSLHD HREC ethics approval 2111-02 and ANZCTR registration 382470.

IJCM_121A: Assessment of risk of foot ulcer in patients with diabetes according to the risk classification consensus of International Working Group on Diabetic Foot (IWGDF) in Ernakulam District, Kerala; a community based cross sectional study

Background: The International Diabetes Federation states that India accounts for 1 in 7 of all adults living with diabetes worldwide. Diabetic foot disease is among the most serious complications of diabetes mellitus as it is a source of major suffering and financial burden for the patient, healthcare professionals and the society in general. The leading cause of lower-limb amputations is diabetes and 40%–85% of these are preventable Objective: Assessment of diabetic foot ulcer risk factors according to International Working Group on the Diabetic Foot (IWGDF) consensus. Methodology: A community based cross-sectional study was done in Ernakulam district involving 600 individuals with diabetes mellitus. The study gathered information on sociodemographic factors, anthropometric details and a detailed foot examination was performed with a IWGDF checklist. The collected data were entered into MS Excel, and the analysis was carried out using SPSS 21.0. Results: Mean age of patients in the study was 61.48 yrs±10.24 years.371 patients (61.83%) were females and 229(38.17%) were males.108 patients (18%) had disturbed sense of vibration (128 Hz). 90 patients (15%) had decreased sensitivity to 10-gram monofilaments. Peripheral arterial disease was present in 47 patients (7.83). 20 patients (3.33%) had history of previous ulcer. 11(1.83%) patients had lower extremity amputation. Patients were classified into four risk groups according to IWGDF criteria. Four hundred and fifty-five patients (75.83%) were in group 0, fifty-five patients (9.1%) in group 1, sixty-six patients (11%) in group 2 and twenty-four patients (4%) in group 3 of IWGDF criteria Conclusion: Routine foot examination in patients with diabetes as per IWGDF guidelines for each risk category will help in prevention of diabetic foot ulcers.

Risk Factors and Frequency of Foot Ulceration in Patients Receiving Chronic Hemodialysis Treatment.

To determine the prevalence and risk factors of foot ulceration in patients receiving hemodialysis treatment. A total of 180 patients who received hemodialysis treatment in two state hospitals and a private health center between April 2017 and September 2017 were included in the study. The researchers collected data using a patient information form and by conducting physical evaluation of the lower extremities. They used the diabetic foot risk assessment algorithm to classify risk according to the data obtained. Of the patients receiving hemodialysis treatment, 6.7% had foot ulceration, 19.4% had a history of foot ulceration, and 8.3% had a history of hospitalization associated with ulceration in a lower extremity. Infected foot ulceration was the most common (6.1%) cause of hospitalizations. In the group with current or past foot ulceration, diabetic nephropathy was the most common etiologic factor of end-stage kidney disease (48.6%); there was a significant between-group difference in diabetic nephropathy (P < .05). Etiologic factors had a significant effect on foot ulcerations: As determined by univariate logistic regression, diabetes (odds ratio [OR], 2.727; P < .05), presence of neuropathy (OR, 4.208; P < .05), low-density lipoprotein cholesterol (OR, 1.013; P < .05), and serum albumin (OR, 0.302; P < .036) all had a statistically significant effect on the presence of foot ulcerations. Patients receiving hemodialysis treatment are at high risk for foot ulceration. Therefore, patient awareness strategies should be expanded to include individuals with end-stage renal disease regardless of diabetes status. Clinical and dialysis nurses should educate these patients about foot ulcerations and foot health to prevent ulcer development.

Plantar pressure gradient and pressure gradient angle are affected by inner pressure of air insole.

Clinically, air insoles may be applied to shoes to decrease plantar pressure gradient (PPG) and increase plantar gradient angle (PGA) to reduce foot ulcers. PPG and PGA may cause skin breakdown. The effects of different inner pressures of inflatable air insoles on dynamic PPG and PGA distributions are largely unknown in non-diabetics and people with diabetes. This study aimed to explore the impact of varying inner air insole pressures on PPG and PGA to establish early mitigation strategies for people at risk of foot ulcers. A repeated measures study design, including three air insoles (80mmHg, 160mmHg, and 240mmHg) and two walking durations (10 and 20min) for a total of six walking protocols, was tested on 13 healthy participants (height, 165.8 ± 8.4cm; age, 27.0 ± 7.3years; and weight, 56.0 ± 7.9kg, BMI: 20.3 ± 1.7kg/m^2) over three consecutive weeks. PPG, a measurement of the spatial variation in plantar pressure around the peak plantar pressure (PPP) and PGA, a variation in the gradient direction values at the three plantar regions, big toe (T1), first metatarsal head (M1), and second metatarsal head (M2), were calculated. This study indicated that PPG was lower at 80mmHg air insoles after 20min of walking in the M1 region (p = 0.010). The PGA in the M2 increased at an air insole of 80mmHg compared to 240mmHg (p = 0.015). Compared to 20min, the 10min walking duration at 240mmHg of air insole had the lowest PPG in the M1 (p = 0.015) and M2 (p = 0.034) regions. The 80mmHg air insole significantly lowered the PPG compared to a 160mmHg and 240mmHg air insole. Moreover, the 80mmHg air insole significantly decreased PPP and increased PGA compared to the 160mmHg and 240mmHg air insole. A shorter walking period (10min) significantly lowered PPG. The findings of this study suggest that people with a higher risk of foot ulcers should wear softer air insoles to have a lower PPG, as well as an increased PGA.

In-Shoe Pressure Measurements in Diabetic Footwear Practice: Success Rate and Facilitators of and Barriers to Implementation.

We aimed to assess the success rate and facilitators of and the barriers to the implementation of in-shoe plantar pressure measurements in footwear practice for people with diabetes at high risk of foot ulceration. Eleven Dutch footwear practices were partly supported in purchasing a pressure measurement system. Over a 2.5-year period, trained shoe technicians evaluated 1030 people with diabetes (range: 13 to 156 across practices). The implementation success and associated facilitators and barriers were evaluated quantitatively using completed measurement forms and pressure measurement data obtained during four monitoring sessions and qualitatively through semi-structured interviews with technicians. Across the 11 practices, the primary target group (people with diabetes and a healed plantar foot ulcer) represented 25-90% of all the patients measured. The results showed that three practices were successful, five moderately successful, and three not successful. The facilitators included support by the company management board, collaboration with a prescribing physician, measurement sessions separate from the outpatient clinic, and a (dedicated) shoe technician experiencing a learning effect. The barriers included investment costs, usability aspects, and limited awareness among shoe technicians. In-shoe plantar pressure measurements can be implemented to a moderate to large degree in diabetic footwear practice. The barriers to and facilitators of implementation are organizational, logistical, financial, or technical, and the barriers are modifiable, supporting future implementation.

Knowledge, Attitude, and Practice of Foot Care and the Risk of Foot Ulcers in Diabetic Patients in Jeddah, Saudi Arabia: A Cross-Sectional Study.

Diabetic patients in Saudi Arabia are often underinformed about proper diabetic foot care. This study aims to determine the knowledge, attitude, and practice of the risk factors of diabetic foot ulcers among diabetic patients in the Jeddah region of Saudi Arabia. A cross-sectional study was done on 210 diabetic patients attending the international diabetic center in Jeddah, Saudi Arabia, during the study period. A validated questionnaire was used to collect data about participants' demographics and knowledge, attitudes, and practices of diabetic foot care. Of the participants, 77 (36.7%) were aged 51-60 years; 161 (76.7%) were male; 153 (72.9%) had a university education; and approximately 138 (65%) had type 2 DM. A majority, 190 (90.5%), acknowledged that DM patients might have reduced foot sensation; 204 (97.1%) agreed that diabetics could develop gangrene; 188 (89.5%) concurred that poor foot sensation increases the risk of foot ulcers; and 193 (91.9%) agreed that poor blood flow to the feet heightens this risk. Among them, 152 (72.4%) demonstrated good knowledge about foot care and the risk of foot ulcers; eight (3.8%) exhibited a positive attitude; and 95 (45.2%) showed a good level of practice. Good knowledge was significantly higher among married patients, and good practice was notably higher among older patients (>50 years). A significant positive correlation was found between knowledge scores and both attitude and practice scores. The study revealed adequate knowledge and practice of foot care and the risk of foot ulcers among diabetic patients. However, a high percentage of negative attitudes toward these issues were observed.

Self-care of chronic illness prevents the risk of diabetic foot ulcers in patients with diabetes: a cross-sectional study

Introduction: Diabetic foot ulcer (DFU) is a serious and chronic complication of diabetes mellitus (DM). This study aims to explain a model of self-care of chronic illness on the prevention of DFU risk in patients with DM, including foot self-care of maintenance, monitoring, and management. Methods: This study was an analytical study with a cross-sectional approach, with 300 patients randomly selected from six Public Health Centers in Surabaya, Indonesia, from June to August 2022. The inclusion criteria were individuals with DM and aged more than 26 years. Exclusion criteria were reading disabilities or having cognitive impairments Data were collected using a questionnaire. The correlation between variables was analyzed using the statistical method of Partial Least Squares. Results: The risk of DFU in patients with DM was 40% with low risk, 38% with moderate risk, 8% with high risk, 5% remission, and 10% with DFU. This research shows that there is a significant correlation between foot self-care management and the risk of DFU, where the p-value = 0.000, while the indicators of foot self-care maintenance and self-care monitoring do not have a significant correlation with the risk of DFU, where the p-value is respectively equal to 0.350 and 0.844. Conclusions: Foot self-care management was a factor that directly correlates with the risk of DFU. Autonomous self-care management behaviors still needed to be improved, because most patients still had these inadequate behaviors. Further research is needed to improve the behavior quality of patients with DM in managing foot care independently.

The Influence of Honey and Hydrogel Products Therapy on Healing Time in Diabetic Foot.

Diabetic foot ulcer is a serious and common complication of diabetes that often leads to significant morbidity and even amputation if not properly treated. Current treatment options, such as wound dressing, have limitations in promoting efficient healing. There is a need for effective interventions that can expedite the healing process and enhance the time required for complete healing. This prospective single-blinded randomized control trial studied diabetic mellitus type 2 patients with ulcer in their second-degree feet from February 2019 to February 2023 in the Diabetic Foot Center, King Fahad Specialist Hospital Al Qassim-KSA. This study involved 120 patients with a mean age of 59.64 ± 10.21. And 63% to 52.5% of them were males and 57% to 47.5% were females. The mean healing time was about 12.76 ± 4.08 days. Cases were divided into 4 equal groups with altered treatment procedures: honey alone, hydrogel alone, honey, and hydrogel combination alternately (3 intervention groups), and fucidin ointment or cream alone (1 control group), with 30 participants in each group. We revealed that the mean healing times for honey alone, hydrogel alone, and honey and hydrogel alternately were 12.20, 13.97, and 10.83 days, respectively. While it was 14.03 days in the control Fucidin ointment or cream [significantly P < .05 (P = .004)]. From the findings of the present study, we noticed that faster healing time among diabetic foot cases could be accomplished by treatment with a combination of honey and hydrogel alternately. Therefore, this therapy is effective in reducing the risk of diabetic foot ulcers.
