Abstract
In this Review, we aim to complement the 2023 update of the guidelines of the International Working Group on the Diabetic Foot. We highlight the complexity of the pathological processes that underlie diabetes-related foot ulceration (DFU) and draw attention to the potential implications for clinical management and outcome. Variation observed in the incidence and outcome of DFUs in different communities might result from differences in study populations and the accessibility of care. Comparing differences in incidence, management, and outcome of DFUs in different communities is an essential component of the quality of disease care. Additionally, these comparisons can also highlight the relationship between DFU incidence, management, and outcome and the structure of local clinical services and the availability of staff with the necessary skills. The clinical outcome is, however, also dependent on the availability of multidisciplinary care and the ability of people with DFUs to gain access to that care.

Abstract
Wound healing is a dynamic and complex process in which the microenvironment at the wound site plays an important role. As a common material for wound healing, dressings accelerate wound healing and prevent external wound infections. Hydrogels have become a hot topic in wound-dressing research because of their high water content, good biocompatibility, and adjustable physical and chemical properties. Intelligent hydrogel dressings have attracted considerable attention because of their excellent environmental responsiveness. As smart polymer hydrogels, thermosensitive hydrogels can respond to small temperature changes in the environment, and their special properties make them superior to other hydrogels. This review mainly focuses on the research progress in thermosensitive intelligent hydrogel dressings for wound healing. Polymers suitable for hydrogel formation and the appropriate molecular design of the hydrogel network to achieve thermosensitive hydrogel properties are discussed, followed by the application of thermosensitive hydrogels as wound dressings. We also discuss the future perspectives of thermosensitive hydrogels as wound dressings and provide systematic theoretical support for wound healing.

Abstract
Diabetes related amputations remain a major global problem, with devastating complications. We critically appraised relevant literature to quantify the prevalence of diabetes related amputations in sub-Saharan Africa (SSA). An electronic search was performed using the EMBASE and PubMed databases until 2020. Twenty-four out of 834 studies retrieved were included. The pooled prevalence of diabetic-related amputations was 36.9% (95%CI: 32.9%-40.8%). Complications of diabetes related amputations included infection, anaemia, foot deformity and mortality. The study revealed a substantial contribution of diabetes to the burden of amputations in SSA and suggests the need for further studies to assess how to reduce the incidence of diabetes, reduce the incidence of and or delay the progression of macro and microvascular complications of diabetes in SSA.

Abstract
OBJECTIVE To describe incidence of foot ulceration and amputation-free survival associated with foot ulceration status in a national population-based cohort study of people with diabetes. RESEARCH DESIGN AND METHODS The study population included 233,459 people with diabetes who were alive in Scotland on 1 January 2012 identified from the national population-based register (national prevalence 4.9%). Characteristics of patients identified from linked hospital and mortality records during follow-up to the end of November 2017 were compared by outcome. Cox regression was used to assess the association between history of foot ulcer and amputation-free survival. RESULTS The population included 23,395 people with type 1 diabetes and 210,064 people with type 2 diabetes. In total there were 13,093 (5.6%) people who had a previous foot ulceration, 9,023 people who developed a first ulcer, 48,995 who died, and 2,866 who underwent minor or major amputation during follow-up. Overall incidence of first-time foot ulcers was 7.8 per 1,000 person-years (95% CI7.6-7.9) and 11.2 (11.0-11.4) for any ulcer. Risk factors for reduced amputation-free survival included social deprivation, mental illness, and being underweight in addition to conventional cardiovascular risk factors. Adjusted hazard ratios (95% CI) were 2.09 (1.89-2.31) for type 1 diabetes and 1.65 (1.60-1.70) for type 2 diabetes. CONCLUSIONS The overall incidence of foot ulceration in a population-based study of people with diabetes was 11.2 per 1,000 person-years. Foot ulceration is associated with lower amputation-free survival rate, a potential measure of effectiveness of care among people with diabetes. Mental illness and social deprivation are also highlighted as risk factors.

Abstract
AIMS The main objective was to assess the incidence of diabetic foot ulcers in type 2 diabetes individuals from primary care centres in Catalonia, Spain. METHODS Prospective observational study in 36 Primary Care centres in Catalonia during February 2018 and July 2019 was conducted. We included participants with type 2 diabetes and a new foot ulcer. We estimated the annual foot ulcer incidence and described the characteristics: presence of comorbidities, clinical parameters and the characteristics of the diabetic foot ulcers (DFU) at inclusion in the study. RESULTS The incidence of a new DFU during the 12-month recruitment period was 0.42%. The mean age of the participants was 72.2 years (± 12.7), the majority of them were males (n = 178; 69.5%). Overall, 43.8% of DFUs were located on the dorsal aspect of toes or interdigital spaces. A percentage of 43.4% of the participants had ulcers of less than 1 cm2 surface. Further, 44.1% of the participants had a neuroischemic, 20.3% a neuropathic, 20.3% an ischemic ulcer. A 25.3% of ulcers with a concomitant peripheral artery disease were infected. CONCLUSIONS Although the incidence found was low, our study shows the great complexity of patients with foot ulcers treated in primary care.

Diabetes-related lower extremity complications in a multi-ethnic Asian population: a 10 year observational study in Singapore. Diabetologia 2021; 64:1538-1549. [PMID: 33885933 PMCID: PMC8187215 DOI: 10.1007/s00125-021-05441-3] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/05/2020] [Accepted: 01/25/2021] [Indexed: 02/06/2023]
Abstract
AIMS/HYPOTHESIS Diabetes progression and complication risk are different in Asian people compared with those of European ancestry. In this study, we sought to understand the epidemiology of diabetes-related lower extremity complications (DRLECs: symptomatic peripheral arterial disease, ulceration, infection, gangrene) and amputations in a multi-ethnic Asian population. METHODS This was a retrospective observational study using data obtained from one of three integrated public healthcare clusters in Singapore. The population consisted of individuals with incident type 2 diabetes who were of Chinese, Malay, Indian or Other ethnicity. We examined incidence, time to event and risk factors of DRLECs and amputation. RESULTS Between 2007 and 2017, of the 156,593 individuals with incident type 2 diabetes, 20,744 developed a DRLEC, of whom 1208 underwent amputation. Age- and sex-standardised incidence of first DRLEC and first amputation was 28.29/1000 person-years of diabetes and 8.18/1000 person-years of DRLEC, respectively. Incidence of both was highest in individuals of Malay ethnicity (DRLEC, 36.09/1000 person-years of diabetes; amputation, 12.96/1000 person-years of DRLEC). Median time from diabetes diagnosis in the public healthcare system to first DRLEC was 30.5 months for those without subsequent amputation and 10.9 months for those with subsequent amputation. Median time from DRLEC to first amputation was 2.3 months. Older age (p < 0.001), male sex (p < 0.001), Malay ethnicity (p < 0.001), Indian ethnicity (p = 0.014), chronic comorbidities (nephropathy [p < 0.001], heart disease [p < 0.001], stroke [p < 0.001], retinopathy [p < 0.001], neuropathy [p < 0.001]), poorer or missing HbA1c (p < 0.001), lower (p < 0.001) or missing (p = 0.002) eGFR, greater or missing BMI (p < 0.001), missing LDL-cholesterol (p < 0.001) at diagnosis, and ever-smoking (p < 0.001) were associated with higher hazard of DRLEC. Retinopathy (p < 0.001), peripheral vascular disease (p < 0.001), poorer HbA1c (p < 0.001), higher (p = 0.009) or missing (p < 0.001) LDL-cholesterol and missing BMI (p = 0.008) were associated with higher hazard of amputation in those with DRLEC. Indian ethnicity (p = 0.007) was associated with significantly lower hazard of amputation. CONCLUSIONS/INTERPRETATION This study has revealed important ethnic differences in risk of diabetes-related lower limb complications, with Malays most likely to progress to DRLEC. Greater research efforts are needed to understand the aetiopathological and sociocultural processes that contribute to the higher risk of lower extremity complications among these ethnic groups.

Abstract
AIMS The aim of our study was to estimate the overall rate of first hospitalizations for diabetic foot (DF) regardless of the outcome in amputations, as well as the mortality rate with their determinants in the period 2012-2016 in Piedmont Region in Italy. METHODS The study included all the subjects registered in the Regional Diabetes Registry and alive as at January 1, 2012. DF cases were identified by record linkage with the regional hospital discharge database. Incident cases of diabetic foot were followed up for mortality. RESULTS The 5-year rates were 1762, 324, and 343 × 100,000 patients for first hospitalization without amputations, with major amputations, and with minor amputations, respectively. Patients not undergoing amputations were more than 70% of the cohort. Patients with the more severe stages of diabetes and those with low education were at higher risk of each type of hospitalization. The risk of death during a mean follow-up of 2.5 years was about 16, 18, and 30% among patients without amputations, with major amputations, and with minor amputations, respectively. Males, insulin-treated patients, those affected with severe diabetes complications, particularly on dialysis, and those with lower levels of education were at higher risk. CONCLUSIONS The heavier burden of DF on hospitalizations is due to cases without amputation, a condition that is seldom considered in the diabetes literature. The severity of diabetes, preexisting complications, and low educational levels are associated with both first hospitalization and subsequent survival at any level of severity of DF.

Abstract
Background Lower extremity amputation (LEA) is a potential sequelae of diabetic foot ulceration (DFU) and is associated with huge morbidly and mortality. Low and middle income countries are currently at the greatest risk of diabetes-related complications and deaths. We sought to identify demographic, clinical and laboratory variables that significantly predict LEA in patients hospitalized for DFU. Methods The Multi-center Evaluation of Diabetic Foot Ulcer in Nigeria (MEDFUN) was an observational study conducted between March 2016 and April 2017 in six tertiary healthcare institutions. We prospectively followed 336 diabetic patients hospitalized for DFU and managed by a multidisciplinary team until discharge or death. Demographic and diabetes-related information and ulcer characteristics were documented. Patients were evaluated for neuropathy, peripheral arterial disease (PAD) and medical co-morbidities while relevant laboratory and imaging tests were performed. The study end-points were ulcer healing, LEA, duration of hospitalization and mortality. Here we present data on amputation. Results One hundred and nineteen subjects (35.4%) underwent LEA during the follow-up period. Univariate predictors of LEA were ulcer duration more than 1 month prior to hospitalization (P < 0.001), PAD (P < 0.001), Wagner grade ≥ 4 (P < 0.001), wound infection (P 0.041), Proteinuria (P 0.021), leucocytosis (P 0.001) and osteomyelitis (P < 0.001). On multivariate regression, only three variables emerged as significant independent predictors of LEA and these include: ulcer duration more than 1 month (O.R. 10.3, 95% C.I. 4.055–26.132), PAD (O.R. 2.8, 95% C.I. 1.520–5.110) and presence of osteomyelitis (O.R. 5.6, 95% C.I. 2.930–10.776). Age, gender, diabetes type and duration, neuropathy, glycemic control and anemia did not predict LEA in the studied population. Conclusion We identified duration of ulcer greater than 1 month, PAD, Wagner grade 4 or higher, proteinuria, leucocytosis, wound infection and osteomyelitis as the significant predictors of LEA in patients hospitalized for DFU. Prompt attention to these risk factors may reduce amputation rate among these patients.

Abstract
Objective: In March 2018, the Explorer study, an international, double-blind, randomised controlled trial (RCT), established that adding a TLC-NOSF (UrgoStart Contact, Laboratoires Urgo, France) dressing to good local standard of care (SoC) significantly and substantially increases wound closure and reduces the healing time of neuroischaemic diabetic foot ulcers (DFU). Besides the TLC-NOSF treatment, the wound duration was the only other covariate that had an influence on the wound closure rate in the regression model used in the original study. The purpose of this work was to further document the impact of wound duration on the healing outcomes of the DFUs included in the Explorer study and to discuss complementary pragmatic observations on the TLC-NOSF effect. Method: In this post-hoc analysis of the Explorer data, the wound closure rates by week 20 are reported for the global cohort (n=240, Intention-to-treat population) and for the treated (n=126) and control groups (n=114) according to DFU duration and location. Results: For the combined group, wound closure rates decreased with the increase of wound duration at baseline (from 57% in wounds ≤2 months to 19% in wounds >11 months). Whatever the wound duration subgroups analysed, higher closure rates were reported in the TLC-NOSF group than in the control group. However, the maximal difference between the two treatments was reported in wounds with a duration of ≤2 months (71% versus 41%, 30 percentage points difference, Relative Risk 1.7, 95% Confidence Interval 1.1 to 2.8). Regarding wound location subgroup analyses, the outcomes were always in favour of the TLC-NOSF treatment, with closure rates ranging between 43% and 61% within the TLC-NOSF group, and between 25% and 40% within the control group. Conclusion: This clinical evidence supports that treating DFUs with TLC-NOSF dressing and good SoC results in higher wound closure rates than with a neutral dressing and the same good standard of care, whatever the duration and the location of the treated wounds. However, the earlier the TLC-NOSF dressing is initiated in DFU treatment, the greater the benefits.

World J Diabetes 2019; 10:200-211. [PMID: 30891155 PMCID: PMC6422858 DOI: 10.4239/wjd.v10.i3.200] [Citation(s) in RCA: 28] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/10/2019] [Revised: 02/23/2019] [Accepted: 03/08/2019] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Nigeria bears the greatest burden of diabetes prevalence in Sub-Saharan Africa. Diabetic foot ulcer (DFU) is a serious and potentially life-threatening complication of diabetes. Significant improvements in diabetic foot incidence and outcomes have been recorded in many Western countries in the past decade. However, the current burden of DFU in Nigeria is largely unknown.
AIM To evaluate the patients’ profile, ulcer characteristics, associated co-morbidities and outcome of patients with DFU in Nigeria.
METHODS Multicenter evaluation of diabetic foot ulcer in Nigeria was a one year multicenter observational study of patients hospitalized for DFU in six tertiary health institutions in Nigeria from March 2016 to March 2017. Demographic and diabetes information, ulcer characteristics and associated co-morbidities were assessed. Relevant laboratory and imaging studies were performed. All patients received appropriate multi-disciplinary care and were followed up until discharge or death. Outcome variables of interest were ulcer healing, lower extremity amputation (LEA), duration of hospitalization and mortality.
RESULTS A total of 336 patients (55.1% male) with mean age of 55.9 ± 12.5 years were enrolled into this study. Majority (96.1%) had type 2 diabetes. Only 25.9% of the subjects had prior foot care knowledge. Most of the subjects presented late to the hospital and median (IQR) duration of ulcer at presentation was 39 (28-54) d. Ulcers were already advanced (Wagner grades ≥ 3) in 79.2% of the subjects while 76.8% of the ulcers were infected at the time of admission. The commonest co-morbidities were systemic hypertension, anemia and hyperglycemic emergencies. One hundred and nineteen subjects (35.4%) suffered LEA while 10.4% left against medical advice. The median (IQR) duration of hospitalization was 52.0 (29-66) d with case fatality rate of 20.5%.
CONCLUSION The burden of DFU in Nigeria is very high. The major gaps include low level of foot care knowledge among diabetic patients, overdependence on self-medication and unorthodox medicine following development of foot ulceration, late hospital presentation, and high amputation and mortality rates. Extensive foot care education within the framework of a multi-disciplinary foot care team is highly desirable.

Abstract
AIMS The aim of this study was to evaluate the prevalence of diabetic foot ulcer and its related risk factors. MATERIALS AND METHODS In this descriptive cross-sectional study, 605 patients with diabetes were evaluated in July 2014. A checklist was used to obtain demographic data, diabetes related data, past medical history, and physical examination data. RESULTS The prevalence of diabetic foot ulcer was 6.4% (95% CI: 4.64-8.73). Seventeen cases of them were female (4.9%). In univariate analysis, the following variables had statistically significant relationship with DFU prevalence: diabetes duration, educational level, 10 g monofilament sensation, Ankle Brachial Index (ABI) and Body Mass Index (BMI). Patients' age, glycemic control and smoking did not show any significant relationship with DFU. After logistic regression analysis, the patients with decreased 10 g monofilament sensation had DFU more than patients with normal sensation (OR = 8.84, 95% CI: 3.5-22.3). Abnormal ABI increased the odds of DFU (OR = 5.6, 95% CI: 1.3-24.18). The DFU prevalence in patients with diabetes duration of 11-20 years, was more than patients with ≤5 years (OR = 3.8, 95% CI: 1.33-10.8).The odds of DFU development in educated patients compared with illiterate patients was 0.27(95% CI: 0.12-0.57). BMI had a significant relationship with DFU prevalence. The odds in overweight patients was 0.259(95% CI: 0.108-0.623) and in obese patients was 0.263 (95% CI: 0.1-0.687). CONCLUSION The prevalence of DFU was 6.4% in this study. Final associated risk factors of DFU were decreased 10 g monofilament sensation, abnormal ABI, diabetes duration, educational level and BMI.

Abstract
AIMS Although diabetic foot ulcer (DFU) is a serious diabetic complication, there have been no large-scale epidemiological studies of DFU in Japan. We prospectively investigated the incidences of DFU and limb amputation, the risk for developing DFU, and mortality in Japanese patients with type 2 diabetes. METHODS We followed 4870 participants (mean age, 65 years) with type 2 diabetes attending an outpatient diabetes clinic for a median of 5.3 years (follow-up rate, 97.7%). The primary outcome was the development of DFU. RESULTS During the follow-up period, DFU occurred in 74 participants (incidence rate, 2.9/1000 person-years) and limb amputation in 12 (incidence rate, 0.47/1000 person-years). DFU recurrence was observed in 21.4% of participants with history of DFU. History of DFU, chronic kidney disease (estimated glomerular filtration rate <60 mL/min/1.73 m2), depressive symptoms, and poor glycemic control were significant risk factors for developing DFU. Survival was significantly lower in participants with DFU and/or history of DFU compared with those without (5-year survival rates: with DFU, 87.7%, without DFU, 95.3%; P < .0001). The hazard ratio for death was 1.80 (95% confidence interval, 1.13-2.73, P = .014) in those with DFU and/or history of DFU in a multi-adjusted model. The most common cause of death was cardiovascular disease among participants with DFU, whereas it was malignant neoplasm among those without. CONCLUSIONS Incidences of DFU and limb amputation were 0.3% and 0.05% per year in this Japanese cohort, respectively. Mortality significantly increased approximately 2-fold in those with DFU and/or history of DFU compared with those without.

Clinical and metabolic response to flaxseed oil omega-3 fatty acids supplementation in patients with diabetic foot ulcer: A randomized, double-blind, placebo-controlled trial. J Diabetes Complications 2017; 31:1394-1400. [PMID: 28716357 DOI: 10.1016/j.jdiacomp.2017.06.010] [Citation(s) in RCA: 64] [Impact Index Per Article: 9.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2017] [Revised: 06/20/2017] [Accepted: 06/20/2017] [Indexed: 01/09/2023]
Abstract
BACKGROUND Data on the effects of flaxseed oil omega-3 fatty acids supplementation on wound healing and metabolic status in subjects with diabetic foot ulcer (DFU) are scarce. OBJECTIVE This study was conducted to evaluate the effects of flaxseed oil omega-3 fatty acids supplementation on wound healing and metabolic status in subjects with DFU. METHODS The current randomized, double-blind, placebo-controlled trial was conducted among 60 subjects (aged 40-85years old) with grade 3 DFU. Subjects were randomly allocated into two groups (30 subjects each group) to receive either 1000mg omega-3 fatty acids from flaxseed oil supplements or placebo twice a day for 12weeks. RESULTS After the 12-week intervention, compared with the placebo, omega-3 fatty acids supplementation resulted in significant decreases in ulcer length (-2.0±2.3 vs. -1.0±1.1cm, P=0.03), width (-1.8±1.7 vs. -1.0±1.0cm, P=0.02) and depth (-0.8±0.6 vs. -0.5±0.5cm, P=0.01). Additionally, significant reductions in serum insulin concentrations (-4.4±5.5 vs. +1.4±8.3 μIU/mL, P=0.002), homeostasis model of assessment-estimated insulin resistance (-2.1±3.0 vs. +1.0±5.0, P=0.005) and HbA1c (-0.9±1.5 vs. -0.1±0.4%, P=0.01), and a significant rise in the quantitative insulin sensitivity check index (+0.01±0.01 vs. -0.005±0.02, P=0.002) were seen following supplementation with omega-3 fatty acids compared with the placebo. In addition, omega-3 fatty acids supplementation significantly decreased serum high sensitivity C-reactive protein (hs-CRP) (-25.5±31.5 vs. -8.2±18.9μg/mL, P=0.01), and significantly increased plasma total antioxidant capacity (TAC) (+83.5±111.7 vs. -73.4±195.5mmol/L, P<0.001) and glutathione (GSH) concentrations (+60.7±140.2 vs. -15.5±129.7μmol/L, P=0.03) compared with the placebo. CONCLUSIONS Overall, omega-3 fatty acids supplementation for 12weeks among subjects with DFU had beneficial effects on parameters of ulcer size, markers of insulin metabolism, serum hs-CRP, plasma TAC and GSH levels. In addition, flaxseed oil omega-3 fatty acids may have played an indirect role in wound healing due to its effects on improved metabolic profiles.
