Abstract
Background Foot infections, a frequent complication of diabetes mellitus, are associated with heavy resource utilization, including antibiotic therapy and surgeries. However, the most common type of isolated pathogen in diabetic foot infections remains unknown. We aimed to identify the most common types of isolated pathogens in diabetic foot infections. Methods This retrospective cohort study was conducted in a specialized medical center in Jeddah, Saudi Arabia. A total of 96 patients diagnosed with diabetes and presented with a foot ulcer showing clinical signs of infection were included. Results The mean age was 63.03 ± 10.88 years, and 67.7% were males. The mean duration of diabetes diagnosis was 21.86 ± 9.66 years, and the majority had foot ulcers for over six weeks. Bacteria were present in 65 patients (67.7%), Gram-negative organisms were observed in 37 patients (38.5%), and Gram-positive organisms were present in 28 patients (29.2%). In the 65 patients with bacterial culture, Staphylococcus aureus was the most common isolated organism and was observed in 18 patients (27.7%), followed by Escherichia coli in 11 (16.9%) and Pseudomonas aeruginosa in 10 (15.4%). Binary regression analyses found that Gram-negative organisms were significantly more multidrug-resistant than Gram-positive organisms (P = 0.012, OR = 7.172, 95% CI = 1.542-33.352). Patient outcomes included healed ulcers (n = 10, 10.4%), minor amputation (n = 16, 16.7%), major amputation (n = 1, 1%), and debridement (n = 48, 50%). Conclusion Gram-negative organisms were predominant in patients with diabetes and foot ulcers having clinical signs of infection. Treatment with an individualized antibiotic regimen is vital in ensuring optimal outcomes and preventing major amputations.

Abstract
The expeditious incidence of diabetes mellitus in Riyadh, Saudi Arabia, there is a significant increase in the total number of people with diabetic foot ulcers. For diabetic lower limb wound infections (DLWs) to be effectively treated, information on the prevalence of bacteria that cause in this region as well as their patterns of antibiotic resistance is significant. Growing evidence indicates that biofilm formers are present in chronic DFU and that these biofilm formers promote the emergence of multi-drug antibiotic resistant (MDR) strains and therapeutic rejection. The current study targeted to isolate bacteria from wounds caused by diabetes specifically at hospitals in Riyadh and assess the bacterium's resistance to antibiotics and propensity to develop biofilms. Totally 63 pathogenic microbes were identified from 70 patients suffering from DFU. Sixteen (25.4%) of the 63 bacterial strains were gram-positive, and 47 (74.6%) were gram-negative. Most of the gram-negative bacteria were resistant to tigecycline, nitrofurantoin, ampicillin, amoxicillin, cefalotin, and cefoxitin. Several gram-negative bacteria are susceptible to piperacillin, meropenem, amikacin, gentamicin, imipenem, ciprofloxacin, and trimethoprim. The most significant antibiotic that demonstrated 100% susceptibility to all pathogens was meropenem. Serratia marcescens and Staphylococcus aureus were shown to have significant biofilm formers. MDR bacterial strains comprised about 87.5% of the biofilm former strains. To the best of our knowledge, Riyadh, Saudi Arabia is the first region where Serratia marcescens was the most common bacteria from DFU infections. Our research findings would deliver information on evidence-based alternative strategies to develop effective treatment approaches for DFU treatment.

Abstract
Diabetic foot ulcer (DFU), a common complication of diabetes, has become a great burden to both patients and the society. The delayed wound closure of ulcer sites resulting from vascular damage and neutrophil dysfunction facilitates bacterial infection. Once drug resistance occurs or bacterial biofilm is formed, conventional therapy tends to fail and amputation is unavoidable. Therefore, effective antibacterial treatment beyond antibiotics is of utmost importance to accelerate the wound healing process and prevent amputation. Considering the complexity of multidrug resistance, biofilm formation, and special microenvironments (such as hyperglycemia, hypoxia, and abnormal pH value) at the infected site of DFU, several antibacterial agents and different mechanisms have been explored to achieve the desired outcome. The present review focuses on the recent progress of antibacterial treatments, including metal-based medications, natural and synthesized antimicrobial peptides, antibacterial polymers, and sensitizer-based therapy. This review provides a valuable reference for the innovation of antibacterial material design for DFU therapy.

Abstract
Lower extremity ulcerations are very common in patients with diabetes. These wounds lead to amputation in a surprisingly large percentage of patients with diabetes. The mortality rate following amputation in a patient with diabetes is alarmingly high. Preventive treatment is pivotal to avoid the numerous complications associated with diabetic ulcerations. However, at the onset of ulceration, early treatment under the supervision and guidance of a specialist can result in remission. Diabetic peripheral neuropathy is also a life-altering and debilitating disease. Although some patients experience numbness, some experience pain that can be sharp, shooting, and tingling. Although treatment is challenging and often requires medication, newer modalities, such as stimulation and physical therapy, have shown promise in reversing the devastating effects of peripheral neuropathy.

Abstract
Background: In this single-center study, we analyzed a retrospective cohort of patients with diabetic foot infections (DFIs) between 2011 and 2020. Patients and Methods: The first and second five-year periods were compared. A poor prognosis was defined as a primary composite end point including re-infection, major amputation, or mortality at six months. Results: A total of 484 patients were enrolled. Overall, 269 patients had the primary composite end point. A substantial decrease was detected in the second five-year period in terms of re-infection (n = 132, 66.0% vs. n = 68, 23.9%; p < 0.001) and mortality (n = 22, 11.0% vs. n = 7, 2.5%; p < 0.001). A total of 798 micro-organisms were isolated from 484 patients. A substantial increase was detected in polymicrobial infections (48.5% vs. 65.1%; p = 0.001) as well as Streptococcus spp. (2.5% vs. 9.2%; p = 0.003), Corynebacterium spp. (9.5% vs. 22.9%; p < 0.001), and extended-spectrum β-lactamase (ESBL) producing Escherichia coli (3.0% vs. 12.7%; p < 0.001) in the second five-year period, whereas the prevalence of multi-drug-resistanct (MDR) Pseudomonas aeruginosa (17.0% vs. 10.2%; p = 0.029) and carbapenem-resistant Acinetobacter baumannii (7.5% vs. 2.8%; p = 0.017) decreased. Multivariable regression analysis revealed that MDR Pseudomonas aeruginosa (odds ratio [OR], 1.917; 95% confidence interval [CI], 1.074-3.420; p = 0.028) and carbapenem-resistant Acinetobacter baumannii (OR, 3.069; 95% CI, 1.114-8.453; p = 0.030) were independent predictors for poor prognosis. Conclusions: This 10-year cohort study provides reassuring information about the changing epidemiology of DFIs and the prognostic determinants in patients with DFIs.

Neutralizing Staphylococcus aureus Virulence with AZD6389, a Three mAb Combination, Accelerates Closure of a Diabetic Polymicrobial Wound. mSphere 2022; 7:e0013022.

Abstract
Nonhealing diabetic foot ulcers (DFU), a major complication of diabetes, are associated with high morbidity and mortality despite current standard of care. Since Staphylococcus aureus is the most common pathogen isolated from nonhealing and infected DFU, we hypothesized that S. aureus virulence factors would damage tissue, promote immune evasion and alter the microbiome, leading to bacterial persistence and delayed wound healing. In a diabetic mouse polymicrobial wound model with S. aureus, Pseudomonas aeruginosa, and Streptococcus pyogenes, we report a rapid bacterial proliferation, prolonged pro-inflammatory response and large necrotic lesions unclosed for up to 40 days. Treatment with AZD6389, a three-monoclonal antibody combination targeting S. aureus alpha toxin, 4 secreted leukotoxins, and fibrinogen binding cell-surface adhesin clumping factor A resulted in full skin re-epithelization 21 days after inoculation. By neutralizing multiple virulence factors, AZD6389 effectively blocked bacterial agglutination and S. aureus-mediated cell killing, abrogated S. aureus-mediated immune evasion and targeted the bacteria for opsonophagocytic killing. Neutralizing S. aureus virulence not only facilitated S. aureus clearance in lesions, but also reduced S. pyogenes and P. aeruginosa numbers, damaging inflammatory mediators and markers for neutrophil extracellular trap formation 14 days post initiation. Collectively, our data suggest that AZD6389 holds promise as an immunotherapeutic approach against DFU complications. IMPORTANCE Diabetic foot ulcers (DFU) represent a major complication of diabetes and are associated with poor quality of life and increased morbidity and mortality despite standard of care. They have a complex pathogenesis starting with superficial skin lesions, which often progress to deeper tissue structures up to the bone and ultimately require limb amputation. The skin microbiome of diabetic patients has emerged as having an impact on DFU occurrence and chronicity. DFU are mostly polymicrobial, and the Gram-positive bacterium Staphylococcus aureus detected in more than 95% of cases. S. aureus possess a collection of virulence factors which participate in disease progression and may facilitate growth of other pathogens. Here we show in a diabetic mouse wound model that targeting some specific S. aureus virulence factors with a multimechanistic antibody combination accelerated wound closure and promoted full skin re-epithelization. This work opens promising new avenues for the treatment of DFU.

Abstract
INTRODUCTION Infected diabetic foot ulcer (IDFU) is a worldwide problem associated with diabetes mellitus. It could lead from soft tissue infection to bone infection and is a leading cause of lower limb amputation. Gram-negative and Gram-positive bacteria, including anaerobic bacteria and fungi, are considered potential causes of infection. The early diagnosis of DFU infection and appropriate treatment based on the identification of the pathogens and their antimicrobial susceptibility pattern is important for good prognosis. Therefore, the purpose of this study was to isolate the bacteria that infect foot ulcers in selected Hospitals and determine their antimicrobial resistance profile. METHOD An institutional-based multicenter, cross-sectional study was conducted in selected Hospitals in Addis Ababa, Ethiopia, from November 2020 to May 2021. A sterile swab was used to collect samples from the foot ulcer and a sterile needle to collect pus. Isolates were identified by culture, Gram-staining, and a series of biochemical tests. For each bacterial species identified, the antibiotic profiling was determined by the Kirby-Bauer disk diffusion method. RESULTS one hundred and twenty-seven pathogenic bacteria were isolated from samples taken from 130 patients with a diabetic foot ulcer. Sixty-eight percent had growth of multiple microorganisms. Two-thirds (66.7%) of the isolates were gram-negative bacteria. The predominant bacterial species were S. aureus 25.19% (32/127), Pseudomonas species 18.89% (24/127), and Escherichia coli 16.53% (21/127). Overall, 92.9% (118/127) of the isolates were identified as multi-drug resistant. Gram-positive isolates were susceptible to chloramphenicol, clindamycin, and amikacin. Gram-negative isolates were also sensitive to chloramphenicol, aztreonam, and amikacin. CONCLUSION The majority of bacteria isolated from patients presenting with Diabetic foot ulcer infections were found to be multi-drug resistant in the study sites of the current study. The results demonstrate the importance of timely identification of infection of diabetic foot ulcers, proper sample collection for identification of the pathogens and for determining their antibiotic susceptibility pattern before initiating antimicrobial treatment.

Abstract
OBJECTIVE Determining the predictive factors of diabetes foot ulcer (DFU) development and lower extremity amputations (LEA) in patients with diabetes mellitus (DM) is of great importance to compose risk stratification models. The aim of this study is to investigate the outcome and predictors of LEA in patients with DFU in large sample of Iranian patients. METHODS This prospective cohort study was conducted during a 2-year period from 2014 to 2016, in Shiraz, southern Iran. All the patients with type 1 and 2 DM and DFU were included in the cohort and were followed for 2 years at least. They were visited in the clinic on a monthly basis and development of new DFU and LEA were recorded. The two-year free-DFU survival and predictors of the DFU development and LEA were recorded. Multivariate regression models were used to determine the factors. RESULTS A total number of 432 patients with mean age of 56.8 ± 13.3 years were included. The two-year DFU-free survival rate was 0.826. The two-year DFU-free survival was associated with male gender (p = 0.005), foot deformity (p = 0.002), history of prior DFU (p < 0.001), cigarette smoking (p = 0.032), nephropathy (p = 0.005), retinopathy (p = 0.007), ischemic heart disease (p = 0.043), and neuropathy (p < 0.001). CONCLUSION Development of new DFU is associated with higher age, longer duration of disease, and type I diabetes. LEA was associated with increased white blood cell (WBC), Creatinine and ulcer history for major amputation and ulcer history, fasting blood sugar (FBS), infection, revascularization history, and foot deformity, for minor amputation.

Abstract
Purpose Diabetic foot infection (DFI) is one of the most feared complications of diabetes. In Sudan, the number of cases and the problems associated with diabetic foot infections increased in recent years. This study aimed to assess the bacteriological profile of patients with DFIs and their antibiotic susceptibility pattern. Methods A descriptive retrospective cross-sectional study was carried out at Surgery Department of Ribat University Hospital. All medical records of patients with DFIs during the period from September 2017 to February 2019 were reviewed using data collection sheet. The collected data were analyzed using Statistical Package for Social Sciences. Results Out of 250 DFI patients, 73.2% of them were males, and 86.4% of them had type 2 diabetes mellitus, and most of them suffered from diabetes for more than 10 years. Regarding culture results, 64.7% and 35.3% of the samples revealed presence of single microorganism and mixed infections, respectively. A total of 335 bacterial isolates were identified, gram-negative were more prevalent than gram-positive organisms. The most frequently isolated organisms were Proteus spp. Staphylococcus aureus, and Escherichia coli. Furthermore, antibiotic susceptibility pattern showed that imipenem, amikacin and vancomycin have the highest activity against isolated bacteria, and all isolates were found to be completely resistant to different cephalosporin drugs. Conclusion Among the studied samples, gram-negative bacteria were found to be more common in DFI patients, Proteus spp. and S. aureus were the most common microorganisms. Moreover, different isolated microorganisms showed to have different degrees of resistance and sensitivity to various antibacterial drugs.

Abstract
Background and objective Diabetic foot ulcers (DFU) have been shown to have a high impact on the patients' perceived health-related quality of life (HRQOL). The aim of this study was to estimate the HRQOL and its related risk factors in patients with foot ulcers associated with type 2 diabetes mellitus (T2DM). Methods This cross-sectional study was performed on 81 patients with DFU, from January 2019 to July 2019 at the Prince Sultan Military Medical City (PSMMC), Riyadh, Saudi Arabia. The study population was purposively and conveniently chosen based on patients' availability during their regular and customary outpatient clinic visits. Using the Arabic version of the Short-Form 36-Item Survey (SF-36), these patients were interviewed and their HRQOL scores were was assessed. The SF-36 covered eight aspects of health such as physical functioning, body pain, limitations in the roles induced by physical health problems, limitations in the roles caused by personal or emotional problems, emotional well-being, social functioning, energy/fatigue, and general health perceptions. Results It was evident that age, gender, education, occupation, smoking, duration of diabetes, hypertension, dyslipidemia, body mass index (BMI), and the number of diabetes-associated complications, hypertension, and dyslipidemia significantly affected the patients' physical functions. The physical health of the patient was strongly influenced by gender, education, occupation, income, BMI, and the number of complications. The emotional health of the patient was affected by dyslipidemia, deformity, prior amputations, as well as BMI and glycosylated hemoglobin (HbA1c). The social standing of the patient was influenced by age, income, education, and occupation. The degree of pain experienced by the patient varied with age and the number of complications, as well as notable differences in their general health. The factors of age, education, occupation, income, and the number of diabetic complications induced several health changes in varying degrees. The patients with DFU revealed overall lower HRQOL relating to all the eight aspects of the SF-36. Conclusion The patients with DFU in Saudi Arabia generally revealed lower HRQOL. However, prospective and large-scale studies are required in the future to support these findings.

Abstract
Diabetic foot infection (DFI) is a serious and common complication of diabetes mellitus. These infections are potentially disastrous and rapidly progress to deeper spaces and tissues. If not treated promptly and appropriately, DFI can be incurable or even lead to septic gangrene, which may require foot amputation. Mostly, these infections are polymicrobial, where Gram-positive pathogens mainly Staphylococcus aureus play a dominant causative role. Methicillin-resistant Staphylococcus aureus (MRSA) is present in 10% to 32% of diabetic infections and is associated with a higher rate of treatment failure, morbidity, and hospitalization cost in patients with DFIs. The increasing resistance of bacteria and the adverse effects pertaining to the safety and tolerability towards currently available anti-MRSA agents have limited the available treatment options for patients with DFI. Infection control, antimicrobial stewardship, and rapid diagnostics based on the microbiological culture and the antimicrobial susceptibility testing results are important components in helping curb this disturbing trend. Emphasis to revisit a vigorous research effort in order to improve the therapeutic options for the increasingly resistant and highly adaptable MRSA is the need of hour. Through this review article, we have made an attempt to explore the ongoing therapeutic trends in the management of DFI and highlighted the challenges in treatment of DFI. We have also given a brief overview of a few novel drugs that are under development to treat MRSA infections.

Abstract
Diabetic foot infection (DFI) should be treated by a multidisciplinary team to prevent amputation and morbid status. As physicians encountering DFI in outpatient clinic, a proper selection of antibiotic treatment and diagnostic approach for a vascular status is essential. We retrospectively investigated the patients with DFI from 2016 to 2017. All patients were examined for vascular status, wound status, and pathologic culture preceding the treatment. No statistical significance was observed between PEDIS grade 1 and 2 and 3 and 4 in culture status and culture results. Association analysis between vascular status and other variables, such as wound score and culture results, has no significant difference. Through these results, the helpful epidemiologic result of microbiology and necessity of examination for peripheral arterial disease were verified.
