Abstract
This study aimed to determine the most accurate microbiological test for the detection of micro-organisms in infected diabetic foot ulcerations in people living with type-2 Diabetes. For 20 eligible patients, a superficial tissue swab and a deep tissue sample were taken during a regular appointment at a Diabetes out-patient's Podiatry Clinic. Two specimens were collected from each wound for microbial culturing after debridement. Infected foot ulcerations were graded according to the Wagner's classification as per clinical protocol. This study found a significant difference [p = 0.028] between the two different samples. The deep tissue sample was found to be more accurate in identifying micro-organisms than the superficial swabs, although the latter is more widely used in clinical practice. Further studies are warranted to provide more evidence to clinicians on the best method to adopt when swabbing different types of diabetic foot ulcerations with different wound classification since, it is clearly still a matter of debate how to detect wound infection.

Abstract
Background and objectives: Diabetic foot stands out as one of the most consequential and devastating complications of diabetes. Many factors, including VIPS (Vascular management, Infection management, Pressure relief, and Source of healing), influence the prognosis and treatment of diabetic foot patients. There are many studies on VIPS, but relatively few studies on "sources of healing". Nutrients that affect wound healing are known, but objective data in diabetic foot patients are insufficient. We hypothesized that "sources of healing" would have many effects on wound healing. The purpose of this study is to know the affecting factors related to the source of healing for diabetic foot patients. Materials and Methods: A retrospective review identified 46 consecutive patients who were admitted for diabetic foot management from July 2019 to April 2021 at our department. Several laboratory tests were performed for influencing factor evaluation. We checked serum levels of total protein, albumin, vitamin B, iron, zinc, magnesium, copper, Hb, HbA1c, HDL cholesterol, and LDL cholesterol. These values of diabetic foot patients were compared with normal values. Patients were divided into two groups based on wound healing rate, age, length of hospital stay, and sex, and the test values between the groups were compared. Results: Levels of albumin (37%) and Hb (89%) were low in the diabetic foot patients. As for trace elements, levels of iron (97%) and zinc (95%) were low in the patients, but levels of magnesium and copper were usually normal or high. There were no differences in demographic characteristics based on wound healing rate. However, when compared to normal adult values, diabetic foot patients in our data exhibited significantly lower levels of hemoglobin, total protein, albumin, iron, zinc, copper, and HDL cholesterol. When compared based on age and length of hospital stay, hemoglobin levels were significantly lower in both the older age group and the group with longer hospital stays. Conclusions: Serum levels of albumin, Hb, iron, and zinc were very low in most diabetic foot patients. These low values may have a negative relationship with wound healing. Nutrient replacements are necessary for wound healing in diabetic foot patients.

Abstract
Living with a diabetes-related foot ulcer has significant lifestyle impacts. Whilst often considered a last resort, amputation can overcome the burden of ulcer management, for an improved quality of life. However, limited research has been conducted to understand how the decision to amputate is made for people with a chronic ulcer when amputation is not required as a medical emergency. Therefore, the aim was to identify and map key concepts in the literature which describe the decision-making for diabetes-related amputations. This review followed Arksey and O'Malley's PRISMA scoping review framework. Five electronic databases and grey literature were searched for papers which described clinical reasoning and/or decision-making processes for diabetes-related amputation. Data were extracted and mapped to corresponding domains of the World Health Organisation's International Classification of functioning, Disability and Health (ICF) framework. Ninety-four papers were included. Personal factors including emotional wellbeing, quality of life, and treatment goals are key considerations for an elective amputation. It is important to consider an individual's lifestyle and personal circumstances, as well as the pathology when deciding between amputation or conservative management. This highlights the importance of a holistic and shared decision-making process for amputation which includes assessment of a person's lifestyle and function.

Abstract
PURPOSE To retrospectively analyze the concordance of bacterial culture between bone tissue and deep soft tissue in diabetic foot osteomyelitis (DFO) patients and clinical characteristics of patients. METHODS This study collected samples from 155 patients with suspected DFO (who required amputation after clinical evaluation). Bacterial culture and drug susceptibility tests were performed on the patients' deep soft tissue and bone tissue, and the consistency between the two was compared. In addition, the differences among DFO patients with different degrees of infection were compared classified by the PEDIS classifications. RESULTS Among the 155 patients diagnosed with DFO, the positive rate of bone culture was 78.7% (122/155). This study cultured 162 strains, including 73 Gram-positive bacteria, 83 Gram-negative bacteria, and 6 fungi. Staphylococcus aureus (33 strains) was the most common bacteria. The overall agreement between bone culture and tissue culture was 42.8%, with Staphylococcus aureus and Enterobacteria having the best (64.3%) and least agreements (27.3%), respectively. The drug sensitivity results in bone culture showed that Staphylococcus aureus was the main Gram-positive bacteria. The bacteria were sensitive to linezolid and vancomycin. Proteus mirabilis was the main Gram-negative bacteria. These were more sensitive than biapenem and piperacillin/tazobactam. Fungi were more sensitive to voriconazole and itraconazole. CONCLUSION The culture results of deep soft tissues near the bone cannot accurately represent the true pathogen of DFO. For DFO patients, bone culture should be taken as much as possible, and appropriate antibiotics should be selected according to the drug susceptibility results.

Abstract
We assessed the risk factors for major amputation of diabetic foot ulcers (DFUs) in patients with diabetic kidney disease (DKD) stages 3b-5. For DFU assessment, in addition to DFU location and presence of infection, ischemia, and neuropathy, vascular calcification was assessed using the medial arterial calcification (MAC) score. Of 210 patients, 26 (12.4%) underwent major amputations. Only the location and extension of DFU, represented by Texas grade differed between the minor and major amputation groups. However, after adjusting for covariates, ulcer location of mid- or hindfoot (vs. forefoot, odds ratio [OR] = 3.27), Texas grades 2 or 3 (vs. grade 0, OR = 5.78), and severe MAC (vs. no MAC, OR = 4.46) was an independent risk factor for major amputation (all P < 0.05). The current use of antiplatelets was a possible protective factor for major amputations (OR = 0.37, P = 0.055). In conclusion, DFU with severe MAC is associated with major amputation in patients with DKD.

Abstract
A diabetic wound presents a severe risk of infections and other complications because of its slow healing. Evaluating the pathophysiology during wound healing is imperative for wound care, necessitating a proper diabetic wound model and assay for monitoring. The adult zebrafish is a rapid and robust model for studying human cutaneous wound healing because of its fecundity and high similarities to human wound repair. OCTA as an assay can provide three-dimensional (3D) imaging of the tissue structure and vasculature in the epidermis, enabling monitoring of the pathophysiologic alterations in the zebrafish skin wound. We present a longitudinal study for assessing the cutaneous wound healing of the diabetic adult zebrafish model using OCTA, which is of importance for the diabetes research using the alternative animal models. We used non-diabetic (n = 9) and type 1 diabetes mellitus (DM) adult zebrafish models (n = 9). The full-thickness wound was generated on the fish skin, and the wound healing was monitored with OCTA for 15 days. The OCTA results demonstrated significant differences between diabetic and non-diabetic wound healing, involving delayed tissue remodeling and impaired angiogenesis for the diabetic wound, leading to slow wound recovery. The adult zebrafish model and OCTA technique may benefit long-term metabolic disease studies using zebrafish for drug development.

Abstract
Diabetes mellitus is a global pandemic, especially in Southeast Asia. Diabetic foot infection (DFI) is a common complication of this condition and causes significant morbidity and mortality in those affected. There is a lack of locally published data on the types of microorganisms and empirical antibiotics being prescribed. This paper highlights the importance of local microorganism culture and antibiotic prescription trends among diabetic foot patients in a tertiary care hospital in central Malaysia. This is a retrospective, cross-sectional study of data taken from January 2010 to December 2019 among 434 patients admitted with diabetic foot infections (DFIs) using the Wagner classification. Patients between the ages of 58 and 68 years old had the highest rate of infection. Pseudomonas Aeruginosa, Proteus spp., and Proteus mirabilis appeared to be the most isolated Gram-negative microorganisms, and Staphylococcus aureus, Streptococcus agalactiae, and MRSA appeared to be the most common Gram-positive microorganisms. The most common empirical antibiotics prescribed were ampicillin/sulbactam, followed by ciprofloxacin and ceftazidime, and the most common therapeutic antibiotics prescribed were ampicillin/sulbactam, ciprofloxacin, and cefuroxime. This study could be immensely pertinent in facilitating future empirical therapy guidelines for treating diabetic foot infections.

Abstract
AIMS To determine whether incident minor and major lower extremity amputations (LEAs) have declined in recent decades in type 2 diabetes. METHODS Participants with type 2 diabetes from the community-based Fremantle Diabetes Study Phases I (FDS1; n = 1,296, mean age 64.0 years, recruited 1993-1996) and II (FDS2; n = 1,509, mean age 65.4 years, recruited 2008-2011) were followed from entry to incident minor/major LEA, death or five years. Cox regression determined hazard ratios (HRs) for each outcome for FDS2 versus FDS1 and independent predictors of incident minor and major LEA in the combined cohort. RESULTS Age- and sex-adjusted HRs (95% CIs) in FDS2 versus FDS1 for incident minor and major LEA were, respectively, 0.60 (0.27, 1.35) and 0.59 (0.22, 1.59). Higher glycated haemoglobin, urine albumin: creatinine (uACR) ratio and peripheral sensory neuropathy (PSN) were independent predictors of incident minor LEA. Higher fasting serum glucose, peripheral arterial disease (PAD), end-stage kidney disease and prior diabetes-related minor LEA were associated with incident major LEA. CONCLUSIONS There were non-significant reductions of approximately 40% in incident minor and major LEA in community-based people with type 2 diabetes during the 15 years between FDS Phases. Predictors of minor/major LEA confirm distinct high-risk patient groups with implications for clinical management.

Abstract
Reulceration is a common complication following ray amputations of the foot. The primary aim of this study was to evaluate the incidence of re-ulceration following isolated and combined central ray amputations. This was a retrospective review of 55 consecutive limbs that underwent central ray amputations at Wake Forest Baptist Medical Centers. Procedures were performed at the 3 central rays or a combination of central rays. Incidence of postoperative ulceration was evaluated on the ipsilateral foot. We hypothesized there would not be an association between which ray was resected and development of reulceration. 24 patients (43%) experienced repeat ulceration following a central ray amputation. Median follow up time was 17.4 months (range 4 days to 99 months). The estimated ulcer recurrence rate at 1 year was 41.8%. There was no statistical difference based on location of amputation (second, third, 4 rays) with regards to reulceration, further amputation, transmetatarsal amputation, or below knee amputations. However, reulceration seemed to be much quicker in those patients undergoing a third ray amputation. Like the medial and lateral rays, central ray amputations can be a good initial salvage procedure to clear devitalized tissue and prevent the spreading of infection. The results of the present study suggest that there is no detectable difference between location of central ray amputations and development of re-ulceration, more proximal amputations, or death among this cohort.

Abstract
There are few data comparing outcomes after hallux amputation or partial first ray resection after diabetic foot ulcer (DFU). In a similar context, the choice to perform one of these two surgeries is attributable to clinician preference based on experience and characteristics of the patient and the DFU. Therefore, the purpose of this study was to determine the more definitive surgery between hallux amputation and partial first ray resection. We abstracted data from a cohort of 70 patients followed for a 1-year postoperative period to support clinical practice. We also attempted to identify patient characteristics leading to these outcomes. Our results suggested no statistical difference between the type of surgery and outcomes such as recurrence of DFU and amputation at 3, 6, and 12 months or death. However, there was a statistically significantly increased likelihood of re-ulceration for patients with CAD who underwent hallux amputation (p = 0.02). There was also a significantly increased likelihood of re-ulceration for people with depression or a history when the partial ray resection was performed (p = 0.02). Patients with prior amputation showed a higher probability of undergoing another re-amputation with partial ray resection (p = 0.01). Although the trends that emerge from this project are limited to what is observed in this statistical context, where the number of patients included and the number of total observations per outcome were limited, it highlights interesting data for future research to inform clinical decisions to support best practices for the benefit of patients.

Abstract
Foot ulcers are a leading cause of morbidity in diabetics. One of the known complications of diabetic foot ulcers is lower limb amputation which makes it a major socioeconomic problem. Currently, there's a lack of knowledge on the predictors of amputations in diabetics with foot ulcers. We performed a systematic review of studies that identified risk factors of amputation in patients with diabetic foot ulcers. This systematic review aims to identify the predictors of amputation in order to optimize the management strategy and care plan. Medline database was searched and inclusion criteria were implemented for the selection of studies. The risk factors extracted were part of four categories: (i) history and physical examination, (ii) ulcer characteristics, (iii) lab results, and (iv) co-morbidities. The data extracted were in the form of odds ratios, 95% confidence intervals, and predictive values. The mean values with standard deviations of the included risk factors were recorded, and the incidence of risk factors among the amputation groups was identified or calculated when the data were sufficient. Seven articles were selected reporting on 3481 patients. This review identified peripheral arterial disease, neuropathy, high Wagner's grade, osteomyelitis, postprandial glucose level, white cell count, c-reactive protein, erythrocyte sedimentation rate, low hemoglobin, and albumin as the most significant predictors of amputation.

Abstract
Diabetic neuropathy (DN) is one of the prevalent forms of neuropathy that involves alterations in biomechanical changes in the human gait. Diabetic foot ulceration (DFU) is one of the pervasive types of complications that arise due to DN. In the literature, for the last 50 years, researchers have been trying to observe the biomechanical changes due to DN and DFU by studying muscle electromyography (EMG) and ground reaction forces (GRF). However, the literature is contradictory. In such a scenario, we propose using Machine learning techniques to identify DN and DFU patients by using EMG and GRF data. We collected a dataset from the literature which involves three patient groups: Control (n = 6), DN (n = 6), and previous history of DFU (n = 9) and collected three lower limb muscles EMG (tibialis anterior (TA), vastus lateralis (VL), gastrocnemius lateralis (GL)), and three GRF components (GRFx, GRFy, and GRFz). Raw EMG and GRF signals were preprocessed, and different feature extraction techniques were applied to extract the best features from the signals. The extracted feature list was ranked using four different feature ranking techniques, and highly correlated features were removed. In this study, we considered different combinations of muscles and GRF components to find the best performing feature list for the identification of DN and DFU. We trained eight different conventional ML models: Discriminant analysis classifier (DAC), Ensemble classification model (ECM), Kernel classification model (KCM), k-nearest neighbor model (KNN), Linear classification model (LCM), Naive Bayes classifier (NBC), Support vector machine classifier (SVM), and Binary decision classification tree (BDC), to find the best-performing algorithm and optimized that model. We trained the optimized the ML algorithm for different combinations of muscles and GRF component features, and the performance matrix was evaluated. Our study found the KNN algorithm performed well in identifying DN and DFU, and we optimized it before training. We found the best accuracy of 96.18% for EMG analysis using the top 22 features from the chi-square feature ranking technique for features from GL and VL muscles combined. In the GRF analysis, the model showed 98.68% accuracy using the top 7 features from the Feature selection using neighborhood component analysis for the feature combinations from the GRFx-GRFz signal. In conclusion, our study has shown a potential solution for ML application in DN and DFU patient identification using EMG and GRF parameters. With careful signal preprocessing with strategic feature extraction from the biomechanical parameters, optimization of the ML model can provide a potential solution in the diagnosis and stratification of DN and DFU patients from the EMG and GRF signals.

Abstract
Diabetic foot is a complex syndrome that is co-morbid with other diabetic complications such as peripheral arterial disease (PAD) and peripheral neuropathy. Patients with the diabetic foot are increasingly prone to diabetic foot ulcers (DFUs) due to a high infection susceptibility and poor wound healing possibly prompting the need for minor or major amputations. We herein highlight the case of a 47-year-old male with a traumatic diabetic foot who necessitated a Ray amputation (RA). The notable aspects of this case are the late presentation of a patient with uncontrolled diabetes who could have avoided this complication if he went to seek help earlier and how diabetic foot is controlled and managed in a low-income resource setting. This case also highlights how physicians can better diagnose and treat diabetic foot complications with a scoring metric.

Abstract
Insulin, a key pleiotropic hormone, regulates metabolism through several signaling pathways in target tissues including skeletal muscle, liver, and brain. In the brain, insulin modulates learning and memory, and impaired insulin signaling is associated with metabolic dysregulation and neurodegenerative diseases. At the receptor level, in aging and Alzheimer’s disease (AD) models, the amount of insulin receptors and their functions are decreased. Clinical and animal model studies suggest that memory improvements are due to changes in insulin levels. Furthermore, diabetes mellitus (DM) and insulin resistance are associated with age-related cognitive decline, increased levels of β-amyloid peptide, phosphorylation of tau protein; oxidative stress, pro-inflammatory cytokine production, and dyslipidemia. Recent evidence shows that deleting brain insulin receptors leads to mild obesity and insulin resistance without influencing brain size and apoptosis development. Conversely, deleting insulin-like growth factor 1 receptor (IGF-1R) affects brain size and development, and contributes to behavior changes. Insulin is synthesized locally in the brain and is released from the neurons. Here, we reviewed proposed pathophysiological hypotheses to explain increased risk of dementia in the presence of DM. Regardless of the exact sequence of events leading to neurodegeneration, there is strong evidence that mitochondrial dysfunction plays a key role in AD and DM. A triple transgenic mouse model of AD showed mitochondrial dysfunction, oxidative stress, and loss of synaptic integrity. These alterations are comparable to those induced in wild-type mice treated with sucrose, which is consistent with the proposal that mitochondrial alterations are associated with DM and contribute to AD development. Alterations in insulin/IGF-1 signaling in DM could lead to mitochondrial dysfunction and low antioxidant capacity of the cell. Thus, insulin/IGF-1 signaling is important for increased neural processing and systemic metabolism, and could be a specific target for therapeutic strategies to decrease alterations associated with age-related cognitive decline.

Abstract
Diabetes and peripheral vascular diseases are accompanied frequently by lower limb ischemia and in minority, need for amputation, as a treatment of last resort. Even after a decision has been made regarding amputation, the procedures are often repeatedly postponed due to more urgent surgeries and lack of operating room availability. This study assessed the possible relationship between the duration of time inpatients wait for semiurgent amputations and the incidence of postamputation complications. A retrospective cohort, including all 360 adult patients who underwent nontraumatic limb amputation due to an ischemic/gangrenous/infected foot in a single center during an 11-year period (2007-2017). Most (96%) of the procedures were major amputations. The mean waiting time until amputation was 3 ± 5 days. Mortality during hospitalization occurred in 101 (28%) patients and re-amputation in 38 (11%). The duration of antibiotic treatment was 11 ± 14 days. The rate of sepsis was 30% (107/360). There was no significant difference between the duration of time until amputation and mortality during hospitalization: among those who waited ≤48 hours, the mortality rate was 27% (60/224) and among those who waited >48 hours 30% (41/136) (p = .5). Patients waiting ≤48 hours had higher re-amputation rates than those waiting >48 (31/223 (14%) vs 7/136 (5%), p = .009). Mortality was associated significantly to patients' age and renal function. Correlation was found between the waiting time until amputation (≤48 or >48 hours) and the rates of in-hospital mortality, sepsis, duration of antibiotic treatment and overall duration of hospitalization. Re-amputation rate was higher in group with the shorter waiting time. This correlation may be explained by the fact that patients who needed urgent amputation had a more extensive and severe disease, and thus tended to require more re-amputation operations.

Abstract
Users of prosthetic devices face the accumulation of potentially drug-resistant pathogenic bacteria on the skin/prosthesis interface. In this study, we took surface swabs of the skin/prosthesis interface of eleven disabled athletes to identify microorganisms present. In addition to determining their antimicrobial resistance profile, we assessed their sensitivity to Manuka honey and Garlic extract (allicin). Eleven volunteers were directed to swab the skin at the skin/prosthesis interface. After initial isolation of microorganisms, we employed the following general microbiological methods: Gram stain, Catalase test, Oxidase test, lactose fermenting capability, haemolytic capability, Staphaurex, mannitol fermenting capability, Streptex; API Staph, 20E, Candida, and BBL crystal identification system tests. Once identified, isolates were analysed for their sensitivity to penicillin, erythromycin, ampicillin, vancomycin, ceftazidime, ciprofloxacin, gentamicin, and colistin-sulphate. Isolates were also analysed for their sensitivity to allicin (Garlic Extract (GE)) and Manuka honey (Medihoney™) (MH). Eleven isolates were identified: Bacillus cereus, Staphylococcus haemolyticus, Staphylococcus aureus, Micrococcus luteus, Pseudomonas oryzihabitans, Micrococcus spp., Bacillus subtilis, Group D Streptococcus, Pantoea spp., Enterobacter cloacae, and Bergeyella zoohelcum. All isolates were resistant to 1 unit of penicillin and 10 μg of ampicillin. Bergeyella zoohelcum was observed to have the widest range of resistance with observed resistance against five of the eight antimicrobials employed in this study. This study highlights the prevalence of uncommon drug-resistant microorganisms on the skin within a vulnerable population, highlighting the potential for MH or GE intervention.

Abstract
Objective: To analyze long-term outcomes following inpatient treatment of infected wounds with antimicrobial or normal saline instillation during negative pressure wound therapy (NPWT). Approach: This was a single-center retrospective study analyzing the course of patients receiving 0.9% normal saline or 0.1% polyhexanide plus 0.1% betaine as instillation for wounds requiring surgery. Measured outcomes included rates of dehiscence, new wounds, re-operations, amputations, and mortality over 5 years. The article adheres to the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement. Results: Forty-two patients received normal saline instillation and 41 the antiseptic solution. Rates of dehiscence, wound recurrence, and re-operations in the saline and antiseptic cohorts were 6.3% and 5.6%, 9.4% and 5.6%, and 14.3% and 9.8%, respectively (p > 0.05). In patients requiring further surgery, time to wound closure averaged 104 and 130 days in the saline and antiseptic cohorts, respectively (p = 0.81). Five-year amputation and mortality rates were 14.3% and 22% (p = 0.36) and 24% and 17% (p = 0.45) in the saline and antiseptic cohorts, respectively. Innovation: To compare clinical outcomes associated with two fundamentally different instillation solutions over the full wound care episode and elucidate the potential impact of these results for future applications. Conclusion: This is the first evaluation of nonsurrogate outcomes of different instillations for NPWT in infected wounds. The results indicate that normal saline instillation outcomes are comparable to those of 0.1% polyhexanide plus 0.1% betaine. The clinical success, cost benefit, and accessibility of normal saline can expand the utilization of this therapeutic approach for larger patient populations.

Abstract
Background and Objectives: To propose a new classification of diabetic foot syndrome adapted for inclusion in the ICD-10 (the ICD-10 is the 10th revision of the International Statistical Classification of Diseases) and providing more reliable data on the number of clinical cases. Materials and Methods: A randomized controlled trial was performed. A total of 180 patients (36.6%) discharged from the hospital after surgical treatment and 312 patients (63.4%) who applied independently were observed and analysed. All patients had type 2 diabetes and were comparable in gender, age, duration of diabetes, area and nature of the wound defect. Results: We proposed to add the following to the existing ICD-10 and the emerging ICD-11 codes: Edf10.0-insulin-dependent diabetes mellitus with diabetic foot syndrome and Edf11.0-non-insulin-dependent diabetes mellitus with diabetic foot syndrome, where "df" is an acronym for diabetic foot. The new classification designates the seven most frequent areas of the lesion and five degrees of depth of soft tissue lesions. Conclusions: The proposed classification adapted for ICD-10 will enable the standardisation of diagnosis, providing a complete picture of this complication of diabetes mellitus, determining the number of amputations and their validity. Accurate statistics will allow for objective funding and timely preventive measures.

Abstract
Chronic wounds that lead to major lower extremity amputation have immense consequences on quality of life, and ultimately, mortality. However, mortality rates after lower extremity amputation for a chronic wound are broad within the literature and have escaped precise definition. This systematic review aims to quantify long-term mortality rates after major lower extremity amputation in the chronic wound population available in the existing literature. Ovid MEDLINE was searched for publications which provided mortality data after major, nontraumatic, primary lower extremity amputations. Lower extremity amputations were defined as below and above the knee amputation. Data from included studies was analyzed to obtain pooled 1-, 2-, 3-, 5- and 10-year mortality rates. Sixty-one studies satisfied inclusion criteria representing 36,037 patients who underwent nontraumatic major lower extremity amputation. Pooled mortality rates were 33.7%, 51.5%, 53%, 64.4%, and 80% at 1-, 2-, 3-, 5- and 10-year follow-up, respectively. Within the 8184 diabetic patients (types 1 and 2), 1- and 5-year mortality was 27.3% and 63.2%. Sources of mortality data were varied and included electronic medical records, national health and insurance registries, and government databases. Mortality after nontraumatic major lower extremity amputation is high, both in patients with diabetes as well as those without. Methods used to measure and report mortality are inconsistent, lack reliability, and may underestimate true mortality rates. These findings illustrate the need for a paradigm shift in wound management and improved outcomes reporting. A focus on amputation prevention and care within a multidisciplinary team is critical for recalcitrant ulcers.

Abstract
PURPOSE Toe amputation is a commonly performed procedure for irreversible foot sepsis. However, outcome and predictors of outcome are poorly understood. Our aim was to determine survival and rate of progression to further amputation following index toe amputation. METHODS Consecutive patients between 2010 and 2015 were included. Progression to further minor amputation, major amputation or death was recorded. Multivariable Cox regression analyses were undertaken to determine independent predictors of outcome and survival. RESULTS One hundred forty-six patients were included, with mean age of 65 years. Fifty-five (37.7%) patients underwent hallux amputation, while 91 (62.3%) underwent amputation of non-hallux digit(s). Following index toe amputation, 63 (43.2%) patients progressed to further minor or major ipsilateral amputation, median time to which was 36 months. Twenty-one patients (14.4%) progressed to major ipsilateral amputation. Patients undergoing index non-hallux amputation were significantly more likely to require further minor amputation (P = 0.050); however, the rate of major amputation between hallux (14.5%) and non-hallux (14.3%) groups was similar. Overall, 5-year ipsilateral amputation-free (iAFS) was 39.6 ± 4.1%, ipsilateral major amputation-free (iMAFS) was 55.9 ± 4.1% and overall survival (OS) was 64.3 ± 4.0% and did not differ between index amputation sites. CONCLUSION Almost half of patients undergoing toe amputation required further digital amputation. However, limb preservation rates are high, and a majority of patients are alive at 5-year follow-up. There was no significant difference in outcome between patients undergoing hallux and non-hallux primary procedures. Overall, increasing age remains the only independent predictor of iMAFS and OS.

Abstract
BACKGROUND The rising prevalence of type 2 diabetes mellitus (T2DM) with the huge burden of diabetic foot amputation is a challenge to the health economy of Pakistan and other countries. Identification of various risk factors for amputation, along with its financial burden, is needed to address this problem. OBJECTIVES This study aimed to determine the financial burden and risk factors associated with T2DMrelated foot amputation. METHODS Retrospective hospital-based study from January 2017 to December 2018. Patients with T2DM with and without amputation were enrolled. The direct medical costs of amputation along with various risk factors, were determined. Risk factors were evaluated by logistic regression analysis. RESULTS A total of 1460 patients with T2DM were included; 484 (33%) patients had an amputation. The mean total cost of below knee, fingers and toe amputation was 886.63±23.91, 263.35 ±19.58 and 166.68 ± 8.47 US$, respectively. This difference among groups was significant (p<0.0001). Male gender (odds ratio, OR: 1.29, 1.01-1.63, p=0.037), peripheral artery disease (OR: 1.93, 1.52-2.46, p=0.000), peripheral neuropathy (OR: 1.31, 1.40-1.63, p=0.000), prior diabetic foot ulcer (OR: 2.02, 1.56- 2.56, p=0.000) and raised glycated haemoglobin (HbA1c) (OR: 3.50, 2.75-4.4, p=0.000) were risk factors for amputation. CONCLUSION The health-related financial impact of amputations is high. Peripheral artery disease, peripheral neuropathy, prior diabetic foot ulcer and raised HbA1c were risk factors for amputation.

Abstract
Diabetes affects multiple systems in complex manners. Diabetic foot ulcers (DFUs) are a result of diabetes‐induced microarterial vessel disease and peripheral neuropathy. The presence of arteriosclerosis‐induced macroarterial disease can further complicate DFU pathophysiology. Recent studies suggest that mesenchymal stromal cell therapies can enhance tissue regeneration. This phase I study was designed to determine the safety and explore the efficacy of local injections of autologous adipose‐derived stromal vascular fraction (SVF) cells to treat nonhealing DFUs greater than 3 cm in diameter. Sixty‐three patients with type 2 diabetes with chronic DFU—all amputation candidates—were treated with 30 × 106 SVF cells injected in the ulcer bed and periphery and along the pedal arteries. Patients were seen at 6 and 12 months to evaluate ulcer closure. Doppler ultrasounds were performed in a subset of subjects to determine vascular structural parameters. No intervention‐related serious adverse events were reported. At 6 months, 51 subjects had 100% DFU closure, and 8 subjects had ≥75% closure. Three subjects had early amputations, and one subject died. At 12 months, 50 subjects had 100% DFU healing and 4 subjects had ≥85% healing. Five subjects died between the 6‐ and 12‐month follow‐up visits. No deaths were intervention related. Doppler studies in 11 subjects revealed increases in peak systolic velocity and pulsatility index in 33 of 33 arteries, consistent with enhanced distal arterial runoff. These results indicate that SVF can be safely used to treat chronic DFU, with evidence of efficacy (wound healing) and mechanisms of action that include vascular repair and/or angiogenesis.

Abstract
BACKGROUND For patients with diabetic foot ulcers, offloading is one crucial aspect of treatment and aims to redistribute pressure away from the ulcer site. In addition to offloading strategies, patients are often advised to reduce their activity levels. Consequently, patients may avoid exercise altogether. However, it has been suggested that exercise induces an increase in vasodilation and tissue blood flow, which may potentially facilitate ulcer healing. The aim of this systematic review was to determine whether exercise improves healing of diabetic foot ulcers. REVIEW We conducted a systematic search of MEDLINE, CINAHL and EMBASE between July 6, 2009 and July 6, 2019 using the key terms and subject headings diabetes, diabetic foot, physical activity, exercise, resistance training and wound healing. Randomised controlled trials were included in this review. Three randomised controlled trials (139 participants) were included in this systematic review. All studies incorporated a form of non-weight bearing exercise as the intervention over a 12-week period. One study conducted the intervention in a supervised setting, while two studies conducted the intervention in an unsupervised setting. Two studies found greater improvement in percentage wound size reduction in the intervention group compared with the control group, with one of these studies achieving statistically significant findings (p < 0.05). The results of the third study demonstrated statistically significant findings for total wound size reduction (p < 0.05), however results were analysed within each treatment group and not between groups. CONCLUSION This systematic review found there is insufficient evidence to conclusively support non-weight bearing exercise as an intervention to improve healing of diabetic foot ulcers. Regardless, the results demonstrate some degree of wound size reduction and there were no negative consequences of the intervention for the participants. Given the potential benefits of exercise on patient health and wellbeing, non-weight bearing exercise should be encouraged as part of the management plan for treatment of diabetic foot ulcers. Further research is required to better understand the relationship between exercise and healing of diabetic foot ulcers.

Abstract
Abstract
Diabetic Neuropathy (DN) is a complication that affects at least half of the patients with Diabetes Mellitus. Unlike other symptoms and signs that may sooner alarm the patients, DN manifestations tend to be rather silent, and so usually neglected by the patient for a long period of time, which can last for years. Therefore it’s a “hidden complication of diabetes” label. Unfortunately, it is only when symptoms already affect the quality of life that the treatment becomes challenging when it comes to speaking of either etiological, symptomatic or rehabilitation strategies. Early diagnosis can also be tricky while aiming for lifestyle corrections and proper individualized treatment strategies. Rehabilitation methods for DN aim especially towards the improvement of articulation mobility and muscular strength amelioration, the suggested brief review of literature promoting this part of therapy essential for both prevention and amelioration of overall morbidity.

Abstract
OBJECTIVE The aim of the study was to evaluate the relationship between pain and quality of life and illness acceptance, anxiety and depression in a group of patients with complicated diabetic foot syndrome, following lower limb amputation. PATIENTS AND METHODS The studies were carried out in three stages: 7 days, 6 months and 12 months after surgery in a group of 100 patients after amputation of the lower limb due to complications resulting from type 2 diabetes. The study was performed using standardised instruments: WHOQOL-BREF, the Acceptance of Illness Scale (AIS), the Hospital Anxiety and Depression Scale (HADS), and the Visual Analog Scale (VAS) for pain intensity assessment. RESULTS Pain occurred in the examined patients throughout the study. The greatest intensity of pain was observed in the postoperative period and significantly weakened over time. Pain intensity was significantly associated with worse overall QoL perceived (-0.255, p=0.011/-0.283, p=0.005) and QoL scores in the physical and psychological domains at the first and second stage of the study (physical domains -0.257, p=0.011/-0.219, p=0.03 and psychological -0.22, p=0.029/-0.24/0.018). The intensity of pain negatively correlates with the acceptance of the disease in all three stages of the study, the greater the severity of pain, the lower the acceptance of illness (-0.298, p=0.003/-0.326, p=0.001/-0.26, p=0.009). The occurrence of anxiety and depression is highly dependent on the severity of pain, especially at the first and second stage of the study (anxiety 0.203, p=0.045/0.257, p=0.01, depression 0.299, p=0.003/0.253, p=0.012). The stronger the pain, the greater the severity of mood disorders. CONCLUSION Pain and its severity are associated with QoL in the patients with complicated diabetic foot syndrome following lower limb amputation. Disease acceptance was lower in patients experiencing more severe pain at all stages of the study. There is an association of pain with the occurrence of anxiety and depression in amputees, especially 6 months after surgery.

Abstract
Diabetes mellitus is a chronic metabolic disease associated with high cardiovascular risk. A vascular complication of diabetes is foot ulcers. Diabetic foot ulcers are prevalent and substantially reduce the quality of life of patients who have them. Currently, diabetic foot ulcer is a major problem for wound care specialists, and its treatment requires considerable health care resources. So far, various therapeutic modalities have been proposed to treat diabetic foot ulcers and one of them is stem cell-based therapy. Stem cell-based therapy has shown great promise for the treatment of diabetic foot ulcers. This strategy has been shown to be safe and effective in both preclinical and clinical trials. In this review, we provide an overview of the stem cell types and possible beneficial effects of stem cell transplantation therapy for diabetic foot ulcers, and an overview of the current status of stem cell research in both preclinical and clinical trial stages of treatment strategies for diabetic foot ulcers.

Abstract
Objective: To explore the clinical efficacy and advantages of five-in-one comprehensive limb salvage technologies for the treatment of severe diabetic foot ulcer (DFU). Approach: Clinical data for 120 patients with severe DFU treated between January 2012 and December 2017 were analyzed retrospectively. The control group (48 cases) was treated with traditional therapies, including controlling blood sugar, improving microcirculation, preserving nerve function, and dressing changes, whereas the experimental group (72 cases) was treated with traditional therapy combined with additional techniques, such as early and thorough debridement, negative pressure wound therapy, revascularization, and skin graft or flap. Ankle-brachial index (ABI), transcutaneous oxygen pressure (TcPO2), wound healing rate, healing time, ulcer recurrence rate, and amputation rate were recorded. Results: Compared with the control group, the experimental group significantly improved wound healing rate (93.1% vs. 72.9%; p < 0.01), decreased wound healing time (16.2 ± 5.4 days vs. 32.2 ± 7.8 days; p < 0.05), reduced major limb amputation rate (1.4% vs. 10.4%, p < 0.05), and ulcer recurrence rate (5.6% vs. 14.6%; p < 0.05). There were no significant differences in amputation rate between experimental and control group (29.2% vs. 33.3%, p = 0.628). After revascularization, the revascularization group showed significantly improved ABI (0.75 ± 0.21 vs. 0.35 ± 0.16, p < 0.05) and TcPO2 (36 ± 6 mmHg vs. 15 ± 4 mmHg, p < 0.05). Innovation: We propose a five-in-one comprehensive treatment method, which provides a multidisciplinary cooperative model for comprehensive medical and surgical treatments for DFU. Conclusion: The five-in-one comprehensive limb salvage treatment technologies played a vital role in enhancing the healing rate of severe DFU, shortening the healing time, and reducing the rate of recurrence and major amputation, thus improving the overall quality of life.

Abstract
OBJECTIVES Bacterial biofilms represent a major impediment to healing in chronic wounds and are largely refractory to the antibacterial agents currently used in wound management. From a repurposing screen of compounds considered safe for topical application in humans, we report the identification of the personal care product preservatives bronopol and bronidox as broad-spectrum antibiofilm agents and potential candidates for reducing biofilm burden in chronic wounds. METHODS Antibiofilm activity was assessed by viable counting against single-species biofilms of Staphylococcus aureus and Pseudomonas aeruginosa in the Calgary Biofilm Device, and against mixed-species biofilms of the two organisms growing on nitrocellulose discs. RESULTS Bronopol and bronidox exhibited broad-spectrum antibiofilm activity that encompassed the two major wound pathogens, S. aureus and P. aeruginosa. When impregnated into gauze dressings at their existing maximum authorized concentrations for safe use and placed onto an established mixed-species biofilm, bronopol and bronidox completely eradicated P. aeruginosa and achieved an ∼5 log10 reduction in the S. aureus population. The antibiofilm action of bronopol and bronidox was attributed to their ability to kill slow- or non-growing bacteria found in biofilms, and both compounds exhibited synergistic antibiofilm effects in combination with established wound-treatment agents. CONCLUSIONS Bronopol and bronidox kill bacteria regardless of growth state, a property that endows them with broad-spectrum antibiofilm activity. As this effect is observed at concentrations authorized for use on human skin, these compounds represent promising candidates for the treatment of chronic wounds.

Abstract
A Holiday Souvenir with Consequences - an Interdisciplinary Challenge Abstract. We describe a patient with a diabetic foot and challenging infectious complications. After a hospital stay in Sri Lanka due to a soft tissue infection of the foot he was relocated to Switzerland. After proof of multiple resistant bacteria, an amputation of the forefoot with a split skin cover was performed, followed by a short resistance-adapted antibiotic treatment, with good clinical results. This case illustrates the increase of multidrug-resistant bacteria, even in Switzerland. It emphasizes the importance of infection control measures in travellers returning from countries with high prevalence of multidrug-resistant bacteria (especially after a hospitalisation), and the need of a close interdisciplinary collaboration in these cases to guarantee the best treatment and to limit the spreading of multidrug-resistant bacteria.

Abstract
Background Currently, the management of ingrown toenail (onychocryptosis) ranges from conservative medical management to surgical treatment. Surgical management is typically performed as an outpatient procedure due to it numerous advantages such as the simplicity of the technique and the low incidence of postoperative complications. The most common postoperative complications are recurrences and surgical site infections, whereas gangrene complicating a surgical site infection has been scarcely reported. We are reporting a rare complication following ambulatory surgery untimely requiring amputation. Case presentation A twelve-year-old boy was referred to our orthopedic surgical department for a surgical site infection complicating an initial surgical management of a left ingrown big toenail leading to a dry gangrene of the affected toe. The gangrene toe was amputated under peripheral nerve block and the patient was discharged home the same day on antibiotics, analgesics and with sessions of rehabilitation and psychological support planned. The postoperative course was uneventful at 6 months of follow-up. Conclusion The authors report this case to draw clinicians’ attention, especially wound care specialists, orthopedists and podiatrists to this rare but potentially debilitating disease.

Abstract
Diabetic foot infections (DFIs) are a common, complex, and costly medical problem with increasing prevalence. Diagnosing DFIs is a clinical challenge due to the poor specificity of the available methods to accurately determine the presence of infection in these patients. However, failure to perform an opportune diagnosis and provide optimal antibiotic therapy can lead to higher morbidity for the patient, unnecessary amputations, and increased healthcare costs. Novel developments in bacteria-specific molecular imaging can provide a non-invasive assessment of the infection site to support diagnosis, determine the extension and location of the infection, guide the selection of antibiotics, and monitor the response to treatment. This is a review of recent research in molecular imaging of infections in the context of DFI. We summarize different clinical and preclinical methods and the translational implications aimed to improve the care of patients with DFI.

Abstract
Diabetic patients frequently develop chronic ulcers of the lower extremities, which are a frequent cause for hospitalization and amputation, placing strain on patients, their families, and healthcare systems. Present therapies remain a challenge, with high recurrence rates. Photobiomodulation (PBM), which is the non-invasive application of light at specific wavelengths, has been shown to speed up healing of chronic wounds, including diabetic foot ulcers (DFUs). PBM produces photophysical and photochemical changes within cells without eliciting thermal damage. It has been shown to promote tissue regeneration and speed up wound repair by reducing inflammation and oxidative stress, accelerating cell migration and proliferation, and promoting extracellular matrix production and release of essential growth factors. The shortage of rigorous, well-designed clinical trials makes it challenging to assess the scientific impact of PBM on DFUs, and lack of understanding of the underlying mechanisms also hinders the conventional use of this therapy. This review gives a glimpse into diabetic wound healing and PBM, and the effects of PBM on diabetic wound healing.

Abstract
It has been demonstrated that Vitamin D (25(OH)D) deficiency is associated with diabetes and with diabetic neuropathy. Some reports stated that vitamin D deficiency is also associated with diabetic foot ulcer and/or infection. Knowing the beneficial effect of vitamin D on wound healing, a quantitative evidence synthesis is needed to look for such association. Medline, Embase, Scopus, CINAHL, Cochrane Library, and Google Scholar were searched for from inception. The outcomes were set to be either the serum 25(OH)D level or the prevalence of patients with 25(OH)D with severe deficiency. Ten studies met the inclusion criteria with 1,644 patients; 817 diabetic patients with foot ulcers and 827 patients having diabetes without foot complications. The weighted mean differences was -0.93 (95% CI = -1.684 to -0.174, I2 = 97.8%, p = 0.01). The odds ratio of having severe vitamin D deficiency was 3.6 (95% CI = 2.940 to 4.415, I2 = 40.9%, p < 0.0001), in favor of the foot group. The quality of the included studies was found to be good to excellent. Diabetic foot complications are associated with significantly lower levels of vitamin D. Patients with diabetic ulcers or diabetic infection are at higher risk of bearing severe vitamin D deficiency. Knowing the beneficial effect of vitamin D on wound healing, it is likely that recognizing and supplementing with vitamin D could prevent or improve the outcomes of diabetic foot complications.

Abstract
Breath analysis is used to detect the composition of exhaled gas. As a quick and non-invasive detection method, breath analysis provides deep insights into the progression of various kinds of diseases, especially those with metabolism disorders. Abundant information on volatile compounds in diabetic patients has been studied in numerous articles in the literature. However, exhaled gas in diabetic patients can be altered by various complications. So far, little attention has been paid to this alteration. In our paper, we found that under air pollution conditions, diabetic patients exhale more nitric oxide. Diabetic patients with heart failure exhale more acetone than those without heart failure. After 13C-labeled glucose intake, patients infected with Helicobacter pylori exhaled more 13C and less 18O than those without infection. Exhalation with chronic kidney disease changes volatile organic compounds on a large scale. Diabetic patients with ketoacidosis exhale more acetone than those without ketoacidosis. Some specific volatile organic compounds also emanate from diabetic feet. By monitoring breath frequency, diabetic patients with obstructive sleep apnea syndrome exhibit a unique breath pattern and rhythm as compared with other diabetic patients, and sleep apnea is prevalent among diabetic patients. In addition to clinical findings, we analyzed the underlying mechanisms at the levels of molecules, cells and whole bodies, and provided suggestions for further studies.

Abstract
OBJECTIVES After surgical or endovascular revascularization, some ischemic lesions will not heal, while some others will heal at a variable period of time from the intervention, indicating a multifactorial interaction between local and systematic "wound healing-promoting" factors. Our objective was to identify predictors of wound healing following revascularization for chronic limb-threatening ischemia (CLTI). METHODS A literature review was performed to identify published research concerning clinical, biochemical, and noninvasive methods as predictors of wound healing time and wound-free period after surgical and endovascular revascularization for CLTI. RESULTS Our review indicated that potential predictors included local wound factors, wound depth, patient's comorbidities, medications, smoking and alcohol abuse, poor vessel runoff, and direct versus indirect revascularization. Among the clinical biomarkers, platelet-derived growth factor, transforming growth factor β, basic fibroblast growth factor, tumor necrosis factor α, interleukin (IL) 1, and IL-6 have been proposed as potential predictors. Furthermore, the potential of noninvasive microcirculation assessment to predict proper wound healing has been the topic of extensive investigation. Among the novel methods, transcutaneous measurement of oxygen partial pressure, skin perfusion pressure, oxygen-to-see method, indocyanine green fluorescence imaging, and multispectral optoacoustic tomography have shown promising results. CONCLUSIONS The risk factor profile of an ischemic lesion in the lower extremities with a delayed/failed healing response, following a successful revascularization, is not fully clarified. Although many predictors have been assessed so far, further research needs to be done to identify the optimal clinical and biochemical indices and the noninvasive technique assessing the microcirculation that is associated with complete wound healing.

Abstract
BACKGROUND AND OBJECTIVE Hedyotis diffusa is an herb used for anti-cancer, anti-oxidant, anti-inflammatory, and anti-fibroblast treatment in the clinical practice of Traditional Chinese Medicine. However, its pharmacological mechanisms have not been fully established and there is a lack of modern scientific verification. One of the best ways to further understand Hedyotis diffusa's mechanisms of action is to analyze it from the genomics perspective. METHODS In this study, we used network pharmacology approaches to infer the herb-gene interactions, the herb-pathway interactions, and the gene families. We then analyzed Hedyotis diffusa's mechanisms of action using the genomics context combined with the Traditional Chinese Medicine clinical practice and the pharmacological research. RESULTS The results obtained in the pathway and gene family analysis were consistent with the Traditional Chinese Medicine clinical experience and the pharmacological activities of Hedyotis diffusa. CONCLUSIONS Our approach can identify related genes and pathways correctly with little a priori knowledge, and provide potential directions to facilitate further research.

Abstract
BACKGROUND AND AIM Diabetic foot is a major comorbidity of diabetes, with 15-25% of diabetic patients developing diabetic foot ulcer during their lifetime. Other major diabetic foot complications include cellulitis, abscess, wet gangrene, dry gangrene, and necrotizing fasciitis. Dry gangrene involves tissue necrosis due to chronic ischemia whereby the tissue becomes numb, dry, wrinkled, and dead. Although diabetic foot complications have been extensively studied in literature, there is limited data on the management of dry gangrene. METHODS We report a case series of 12 patients with diabetes-related dry gangrene in the toes, initially planned to be managed conservatively with autoamputation. RESULTS One patient had an autoamputation, while eight patients underwent surgical amputations (six major amputations, two minor amputations) for better clinical outcomes. Two patients died, while no change was observed in one patient even after 12 months of follow-up. CONCLUSION Managing diabetic dry toe gangrene by waiting for autoamputation may lead to worse clinical outcomes and should be practiced cautiously on a case-by-case basis. Early surgical intervention should be opted to improve patients' quality of life.

Abstract
Background Foot infection is a major complication of diabetes mellitus (DM) and its agents are usually polymicrobial. This study aims to describe the agent and determine the association between polymicrobial infections and the severity of diabetic foot infections (DFI) and their outcomes. Methods This retrospective cohort study was conducted during one year and it involved 104 patients. Their records were reviewed and assessed. The causative agents and its sensitivity pattern were noted. The results were presented as descriptive statistic and analysed. Results A total of 133 microorganisms were isolated with 1.28 microorganisms per lesion. The microorganism isolated were 62% (n = 83) GN (Gram-negative) and 38% (n = 50) GP (Gram-positive). GN microorganisms include Pseudomonas spp (28%), Proteus spp (11%), Klebsiella spp (8%) and E. coli (4%). Staphylococcus aureus (54%) was predominant among GP, followed by Group B Streptococci (26%) and Enterococcus spp (6%). Thirty patients (28.8%) had polymicrobial infections. The association between the quantity of microorganisms and severity of DFI was significant. Among severe DFI cases, 77.8% with polymicrobial microorganisms underwent amputation compared to 33.3% with monomicrobial infection. Conclusion GN microorganisms were predominantly isolated from DFIs and remained sensitive to widely used agents. Polymicrobial infections were associated with DFI severity.

Abstract
BACKGROUND A kinetic change in the foot such as altered plantar pressure is the most common etiological risk factor for foot ulcers in people with diabetes mellitus. Kinematic alterations in joint angle and spatiotemporal parameters of gait have also been frequently observed in participants with diabetic peripheral neuropathy (DPN). Diabetic peripheral neuropathy leads to various microvascular and macrovascular complications of the foot in type 2 diabetes mellitus. There is a gap in the literature for biomechanical evaluation and assessment of type 2 diabetes mellitus with DPN in the Indian population. We sought to assess and determine the biomechanical changes, including kinetics and kinematics, of the foot in DPN. METHODS This cross-sectional study was conducted at a diabetic foot clinic in India. Using the purposive sampling method, 120 participants with type 2 diabetes mellitus and DPN were recruited. Participants with active ulceration or amputation were excluded. RESULTS The mean ± SD age, height, weight, body mass index, and diabetes duration were 57 ± 14 years, 164 ± 11 cm, 61 ± 18 kg, 24 ± 3 kg/m2, and 12 ± 7 years, respectively. There were significant changes in the overall biomechanical profile and clinical manifestations of DPN. The regression analysis showed statistical significance for dynamic maximum plantar pressure at the forefoot with age, weight, height, diabetes duration, body mass index, knee and ankle joint angle at toe-off, pinprick sensation, and ankle reflex ( R = 0.71, R2 = 0.55, F12,108 = 521.9 kPa; P = .002). CONCLUSIONS People with type 2 diabetes mellitus and DPN have significant changes in their foot kinetic and kinematic parameters. Therefore, they could be at higher risk for foot ulceration, with underlying neuropathy and biomechanically associated problems.

Abstract
We investigated the effects of photobiomodulation therapy (PBMT) and conditioned medium (CM) of human bone marrow mesenchymal stem cells (hBM-MSC) individually and/or in combination on the stereological parameters and the expression of basic fibroblast growth factor (bFGF), hypoxia-inducible factor (HIF-1α), and stromal cell-derived factor-1α (SDF-1α) in a wound model infected with methicillin-resistant Staphylococcus aureus (MRSA) in diabetic rats. CM was provided by culturing hBM-MSCs. Type 1 diabetes mellitus (T1DM) was induced in 72 rats, divided into four groups, harboring 18 rats each: group 1 served as a control group, group 2 received PBMT, group 3 received CM, and group 4 received CM + PBMT. On days 4, 7, and 15, six animals from each group were euthanized and the skin samples were separated for stereology examination and gene expression analysis by real-time polymerase chain reaction. In the CM + PBMT, CM, and PBMT groups, significant decreases were induced in the number of neutrophils (1460 ± 93, 1854 ± 138, 1719 ± 248) and macrophages (539 ± 69, 804 ± 63, 912 ± 41), and significant increases in the number of fibroblasts (1073 ± 116, 836 ± 75, 912 ± 41) and angiogenesis (15 230 ± 516, 13 318 ± 1116, 14 041 ± 867), compared with those of the control group (2690 ± 371, 1139 ± 145, 566 ± 90, 12 585 ± 1219). Interestingly, the findings of the stereological examination in the CM + PBMT group were statistically more significant than those in the other groups. In the PBMT group, in most cases, the expression of bFGF, HIF-1α, and SDF-1α, on day 4 (27.7 ± 0.14, 28.8 ± 0.52, 27.5 ± 0.54) and day 7 (26.8 ± 1.4, 29.6 ± 1.4, 28.3 ± 1.2) were more significant than those in the control (day 4, 19.3 ± 0.42, 25.5 ± 0.08, 22.6 ± 0.04; day 7, 22.3 ± 0.22, 28.3 ± 0.59, 24.3 ± 0.19) and other treatment groups. The application of PBMT + CM induced anti-inflammatory and angiogenic activities, and hastened wound healing process in a T1 DM model of MRSA infected wound.

Abstract
BACKGROUND Peripheral arterial disease is very common in patients with diabetes, but it remains grossly under-recognized in this type of patients. Ankle brachial index (ABI) is a simple, non-invasive and reproducible method for detection and improving risk stratification. However, the sensitivity appears to be lower in diabetic patients and, false 'high' readings occur because of the arterial calcification of the vessel media which render the vessels incompressible. MATERIALS AND METHODS The study evaluated the prevalence of a low ABI <0.9 in diabetic patients in a hospital-based cross sectional observational study. The study has been registered. RESULTS The prevalence of peripheral arterial disease in diabetics with ABI< 0.9 was 18%. The majority (77%) of responders were asymptomatic with mild PAD (ABI 0.7-0.9). Age >60 years, hypertension (systolic BP > 140 mmHg) and presence of foot ulcer were identified as independent risk factors. 22 participants (4.4%) of the 500 had ABI greater than 1.3 but were excluded in the analysis. CONCLUSION The prevalence of PAD in diabetics measured by the ABI index was low and the majority in our setting had mild PAD and were asymptomatic. ABI could be used in patients with diabetes, but values should be interpreted with precision, according to the clinical situation as higher values are common.

Abstract
The lifetime risk for diabetic patients to develop a diabetic foot ulcer (DFU) is 25%. In these patients, the risk of amputation is increased and the outcome deteriorates.More than 50% of non-traumatic lower-extremity amputations are related to DFU infections and 85% of all lower-extremity amputations in patients with diabetes are preceded by an ulcer; up to 70% of diabetic patients with a DFU-related amputation die within five years of their amputation.Optimal management of patients with DFUs must include clinical awareness, adequate blood glucose control, periodic foot inspection, custom therapeutic footwear, off-loading in high-risk patients, local wound care, diagnosis and control of osteomyelitis and ischaemia.

Abstract
Diabetes is associated with various complications and reduced quality of life. Of the many complications, some are life-threatening. Among these, foot complications remain an important concern. The major foot complications include foot ulceration, cellulitis, abscess, wet gangrene, dry gangrene, and necrotizing fasciitis, with different pathophysiological concepts behind each of them. Gangrene occurs due to reduced blood supply in the body tissues that leads to necrosis. This condition may arise because of an injury, infection, or other health conditions, majorly diabetes. Gangrene is classified as dry, wet, and gas gangrene. In case of wet and gas gangrene, surgical amputation is usually performed to prevent the spread of infection to other tissues. In dry gangrene, due to the presence of clear demarcation, autoamputation is preferred in certain parts of the globe. The present review aims to analyze the mode of dry gangrene management in diabetic patients based on previous evidence and plans to highlight various management strategies available for dry gangrene and the advantages/disadvantages of different treatments with special consideration to autoamputation.

Abstract
Objectives The initial phase of infection of a foot ulcer in a person with diabetes is often categorized as mild. Clinicians usually treat these infections with antimicrobial therapy, often applied topically. Some experts, however, believe that mild diabetic foot ulcer infections will usually heal with local wound care alone, without antimicrobial therapy or dressings. Methods To evaluate the potential benefit of treatment with a topical antibiotic, we performed a single-center, investigator-blinded pilot study, randomizing (1:1) adult patients with a mild diabetic foot ulcer infection to treatment with a gentamicin-collagen sponge with local care versus local care alone. Systemic antibiotic agents were prohibited. Results We enrolled a total of 22 patients, 11 in the gentamicin-collagen sponge arm and 11 in the control arm. Overall, at end of therapy, 20 (91%) patients were categorized as achieving clinical cure of infection, and 2 (9%) as significant improvement. At the final study visit, only 12 (56%) of all patients achieved microbiological eradication of all pathogens. There was no difference in either clinical or microbiological outcomes in those who did or did not receive the gentamicin-collagen sponge, which was very well tolerated. Conclusion The results of this pilot trial suggest that topical antibiotic therapy with gentamicin-collagen sponge, although very well tolerated, does not appear to improve outcomes in mild diabetic foot ulcer infection.

Biomaterials 2018; 169:61-71. [PMID: 29631168 DOI: 10.1016/j.biomaterials.2018.03.049] [Citation(s) in RCA: 28] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2018] [Revised: 03/23/2018] [Accepted: 03/28/2018] [Indexed: 12/19/2022]
Abstract
Decellularized biologic scaffolds are gaining popularity over synthetic biomaterials as naturally derived materials capable of promoting improved healing. Nevertheless, the most widely used biologic material - acellular dermal matrix (ADM) - exhibits slow repopulation and remodeling, which prevents integration. Additionally, engineering control of these materials is limited because they require a natural source for their production. In the current report, we demonstrate the feasibility of using genetically engineered animals to create decellularized biologic scaffolds with favorable extracellular matrix (ECM) properties. Specifically, we utilized skin from thrombospondin (TSP)-2 KO mice to derive various decellularized products. Scanning electron microscopy and mechanical testing showed that TSP-2 KO ADM exhibited an altered structure and a reduction in elastic modulus and ultimate tensile strength, respectively. When a powdered form of KO ADM was implanted subcutaneously, it was able to promote enhanced vascularization over WT. Additionally, when implanted subcutaneously, intact slabs of KO ADM were populated by higher number of host cells when compared to WT. In vitro studies confirmed the promigratory properties of KO ADM. Specifically, degradation products released by pepsin digestion of KO ADM induced greater cell migration than WT. Moreover, cell-derived ECM from TSP-2 null fibroblasts was more permissive to fibroblast migration. Finally, ADMs were implanted in a diabetic wound model to examine their ability to accelerate wound healing. KO ADM exhibited enhanced remodeling and vascular maturation, indicative of efficient integration. Overall, we demonstrate that genetic manipulation enables engineered ECM-based materials with increased regenerative potential.
