Abstract
Diabetes is a chronic disease that is considered one of the most stubborn global health problems that continues to defy the efforts of scientists and physicians. The prevalence of diabetes in the global population continues to grow to alarming levels year after year, causing an increase in the incidence of diabetes complications and health care costs all over the world. One major complication of diabetes is the high susceptibility to infections especially in the lower limbs due to the immunocompromised state of diabetic patients, which is considered a definitive factor in all cases. Diabetic foot infections continue to be one of the most common infections in diabetic patients that are associated with a high risk of serious complications such as bone infection, limb amputations, and life-threatening systemic infections. In this review, we discussed the circumstances associated with the high risk of infection in diabetic patients as well as some of the most commonly isolated pathogens from diabetic foot infections and the related virulence behavior. In addition, we shed light on the different treatment strategies that aim at eradicating the infection.

Sultana R, Ahmed I, Saima S, Salam MT, Sultana S. Diabetic foot ulcer-a systematic review on relevant microbial etiology and antibiotic resistance in Asian countries. Diabetes Metab Syndr 2023; 17:102783. [PMID: 37257221 DOI: 10.1016/j.dsx.2023.102783] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Revised: 04/15/2023] [Accepted: 05/03/2023] [Indexed: 06/02/2023]
Abstract
BACKGROUND AND AIMS Diabetic foot ulcer (DFU) is one of the most common but uncontrolled health issues of diabetic patients that needs more therapeutic considerations. This systematic review aims to study the current status of the etiological agents responsible for DFU, their frequency in some of the most occurring Asian countries, and their antibiotic resistance pattern based on available studies. METHODS Here, the literature survey was conducted on all the DFU studies with the records of etiological agents and conventional therapeutic treatment published until March 2021 using Medical Literature Analysis and Retrieval System Online (MEDLINE) and Web of Science Core Collection (WoSCC) database. RESULTS Overall, in our study, a total of 73 studies representing 12 Asian countries worldwide have been included. We found that the highest number of studies were reported from India (45%) followed by Pakistan (11%), China, Iran and others. 71% of recent studies reported DFU being attributed to poly-microbial infections while the dominant position was significantly secured by Gram- negative bacteria (77%, p = 0.34). Staphylococcus aureus was found to be the most prevalent isolate followed by Pseudomonas and then Escherichia coli (mean value - 22%, 17%, and 15% respectively). Antibiotic sensitivity pattern was determined based on availability in terms of median resistance (MR) and interquartile range (IQR) which showed the growing resistance developed by both Gram-positive and Gram-negative isolates. Gram positive pathogens were still reported as susceptible to vancomycin (MR 0%, IQR 0-22.8%), linezolid (MR 0%, IQR 0-15.53%) and imipenem (MR 11%, IQR 0-23.53%). Carbapenem genera, colistin, and amikacin were the most effective drugs against Gram-negative pathogens. CONCLUSION The findings of this study highly recommend searching for alternative and complementary therapeutic regimens instead of prescribing conventional drugs blindly without investigating the progression of the stages of the ulcer, which may help reduce the medical and economic burden of this disease.

Abstract
Pseudomonas aeruginosa is a difficult-to-treat pathogen that is frequently involved with chronic wound infections. Here, we conducted a literature search of world-wide studies published between 2005 and 2022 that described the microbiological profiles of chronic wound infections. For each continent, a hierarchy of pathogens was created to define the organisms that were most frequently isolated in each region. Except for South America, P. aeruginosa was the second most common organism in each major continent, with Staphylococcus aureus being the most abundant pathogen overall. When individual countries were evaluated, P. aeruginosa was the most frequently isolated organism in several Southeast Asia nations including India and Malaysia. P. aeruginosa was less commonly isolated from diabetic foot infections in North America, Europe, and Africa in comparison to other types of chronic wound infections. Additionally, the Levine wound swab technique may be a quick and painless way to isolate P. aeruginosa from wound infections, but the isolation of P. aeruginosa does not seem to be an informative predictor of the patient's clinical course. A multivariate risk assessment that accounts for the regional frequency of P. aeruginosa isolation may be an appropriate way to guide empiric management of chronic wound infections.

Distribution of Causative Microorganisms in Diabetic Foot Infections: A Ten-Year Retrospective Study in a Tertiary Care Hospital in Central Malaysia. Antibiotics (Basel) 2023; 12:antibiotics12040687. [PMID: 37107049 PMCID: PMC10135124 DOI: 10.3390/antibiotics12040687] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2022] [Revised: 12/07/2022] [Accepted: 12/16/2022] [Indexed: 04/03/2023] Open
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 This pilot study aimed to assess the acceptability of an intensive community-based intervention, and to get a preliminary estimate of the effect size of the intervention for people with type 2 diabetes in Kupang, Indonesia. METHODS Pilot of a cluster randomised trial involving sixty-seven participants. The participants were recruited from four Primary Health Centres (PHCs), and were allocated into groups (intervention: 36; control: 31) based on the PHCs they were registered in. The 3-month intervention consisted of weekly group activities including physical activity and education. Control was usual care. The outcomes were change in HbA1c, medication adherence, and self-management behaviours. To test our intervention, we used a mixed linear model, with participants nested within cluster/health centre. RESULTS Participants were 60% female, mean age 57, and had diabetes for an average of 4.5 years. Groups did not differ at baseline. Counter to prediction, no effects of the intervention over usual care were observed on the outcomes measured. However, both groups made statistically significant improvements in HbA1c (intervention from 8.3% ± 1.9 to 7.8% ± 1.8; control from 8.4% ± 2.6 to 7.9% ± 2.5). CONCLUSIONS The effect of the intervention did not differ from usual care. However, both groups made improvements in HbA1c outcome, suggesting that the project might have indirectly triggered more intensive care for diabetes patients.

Abstract
Background: Diabetic Foot Ulcer (DFU) has been associated with a high mortality rate of Diabetes Mellitus (DM) patients. Both behavioral and biological factors cause predisposition to DFU. Purpose: This research describes the profile of hospitalized DFU patients at a tertiary care hospital in Surabaya. Methods: A retrospective descriptive study that analyzed medical records of hospitalized T2DM patients with DFU in Dr. Soetomo General Hospital. Sampled respondents were patients ≥ 21 years old who were hospitalized between 2016–2018. Demographic data, clinical characteristics, medical histories, length of hospital stay, laboratory results, precipitating factors, microorganism culture results, treatment, and outcome were analyzed. Descriptive analysis is presented in the form of narratives, tables, and diagrams. Results: 9.08% of hospitalized Type 2 DM (T2DM) cases were related to foot ulcers. The average patient age was 57.00 ± 9.83 years with no gender predominance. DM was poorly controlled (Mean HbA1C 9.78±2.83%; RBG 251.83 ± 158.15 mg/dL). The majority of patients had sepsis (68.26%) and renal function impairment (62.72%). Ulcers with Wagner grades of 4–5 were frequent (41.31%). The highest percentage of sepsis (80.49%) and the average leukocyte level (22.60±11.95 x109/L) were found in gangrenous feet. Anemia was more predominant and severe in ulcers with higher Wagner grades. Trauma and Escherichia coli were the most common precipitating factors and microorganisms isolated, respectively. Amputation was performed for 82.36% of patients who were admitted to hospital with gangrene. The Lower Extremity Amputation (LEA) and mortality rates were 14.11% and 40.93%, respectively. Conclusion: DFUs were found to have a relatively high prevalence among T2DM patients, and must never be neglected due to the high associated mortality rate.

Abstract
PURPOSE Diabetic foot ulcer (DFU) is a common chronic complication of type 2 diabetes mellitus (T2DM) in Indonesia, with a prevalence of 7.3%. However, the characteristics of these patients remain unclear. We investigated the characteristics of patients with DFU without peripheral arterial disease (PAD) and analyzed non-vascular factors related to severity of DFU in a tertiary care national referral hospital in Indonesia. METHODS This was a cross-sectional study including 123 hemodynamically stable DFU patients without PAD recruited from Dr. Cipto Mangunkusumo National General Hospital, Jakarta, Indonesia from 2010-2015. RESULTS DFU patients were predominantly over 50 years old (75.6%) and diagnosed with T2DM for 5 years with poor glycemic control (82.7%) and peripheral neuropathy (91.3%). Most patients had anemia (86.7%), leukocytosis (84.6%), and were undernourished, as characterized by a low lipid profile (90.8%) and hypoalbuminemia (83.7%). Most had extensive size of ulcer at the initial visit, with a median size of 16.23 (2.92-60.16) cm2. Ulcers were mostly located of the forefoot (62.5%) and were caused by mechanical trauma (46.2%). Bivariate analysis revealed that significant factors for the development of DFU were related to DFU size, including duration of T2DM (p = 0.04), leukocyte levels (p = < 0.01), and thrombocyte levels (p = < 0.01). Multivariate analysis showed leucocyte (p = 0.03) and thrombocyte (p = 0.023) had significantly correlated with DFU severity. CONCLUSION Leucocyte and thrombocyte may be the greatest contributing non-vascular factors for severity of DFU in Indonesia.

Abstract
Diabetic foot is a serious infection of the lower limbs. It is caused by diabetic neuropathy and vascular disease. It is also the primary cause of disability and death in patients with severe diabetes, so prompt treatment is essential for positive outcomes. The clinical use of nano-silver dressings can be considered to further optimize the treatment process and improve the treatment efficacy in diabetic foot patients. Nano-silver dressings have a larger contact surface and a stronger bactericidal effect when compared to ordinary silver dressings. Besides, it can be disinfected repeatedly to better wound infection control and promote wound healing. The current article discusses the pathogenesis of diabetic foot, diabetic foot dressing treatment, the application of nanotechnology in diabetic foot treatment, the efficacy evaluation of different dressings, and the practical prospects of adopting nanotechnology in the treatment of diabetic foot.

Abstract
BACKGROUND AND AIMS Diabetes is one of the most critical diseases particularly in developing countries such as Indonesia. Various diabetes approaches have been well conducted to prevent complications. However, little has been discussed in association with the achievement of self- and family management support programs in Indonesia. Thus, the objective of the umbrella review is to evaluate the implementation of the self- and family management support programs among Indonesian with diabetes. METHOD To guide this review, the revised self- and family management framework developed by Grey, Schulman-Green, Knafl, and Reynolds (2015) was used. A literature search was conducted via online databases including Cochrane, Scopus, ProQuest, SAGE, EBSCO, and PubMed. The inclusion criteria were diabetes studies related to self- and family management in Indonesia; articles published from 2000 to 2019; quantitative, qualitative, and review studies; used humans as research subjects; and English articles were prioritized. Meanwhile, the exclusion criteria were studies not addressing the nature of self- and family management in Indonesia, laboratory-based research using human cell and study protocol. RESULTS A total of 78 studies were involved in the final analysis. The facilitators and barriers, process, and outcomes (distal and proximal) were presented. The results indicated that the implementation of the self- and family management process generated favorable outcomes for the diabetes population in Indonesia. CONCLUSIONS The self- and family management support program is a promising strategy to improve the facilitators and overcome the barriers to diabetes care. Patients, families, diabetes nurses, and health policymakers are recommended to work in tandem to achieve successful diabetes care, particularly in the community.

Abstract
Antimicrobial peptides (AMPs) are emerging as a viable alternative to antibiotics attributable to their potent antimicrobial effects and low propensity for resistance development, especially in chronic infected wounds. The development of an optimized topical formulation of AMPs is thus warranted. Preformulation studies for determination of the suitability and optimization requirements of AMPs in topical formulation development are important. Therefore, we sought to investigate the preformulation studies for a novel bacteriocin garvicin KS (GarKS), which is composed of three peptides (GakA, GakB, and GakC). The effects of physiological fluids and varying temperatures on GarKS peptide stability were determined. The antimicrobial effects of the peptides and their combinations were evaluated in Staphylococcus aureus (methicillin sensitive and resistant strains). Furthermore, their effects on fibroblast viability and proliferation were determined. The GarKS peptides were stable in water and PBS at room and physiological temperatures, however, the peptides were significantly degraded in simulated wound fluid. The antimicrobial and fibroblast cell viability/proliferation effects of either individual GarKS peptides or their combinations varied. A careful consideration of the peptide stability, antimicrobial efficacy, and fibroblast viability/proliferation effects suggests GakA+GakB as a potent combination for the development of an optimized topical formulation of GarKS peptides.

Abstract
This study collected wound swab samples from 50 diabetic patients, especially in Wagner's grade 2 (28) and grade 3 (22) foot ulcers. The samples were processed and subjected to bacterial isolation and characterization. The obtained diabetic foot ulcer (DFU) bacterial isolates were also subjected to antibiotic susceptibility assay. All the collected samples were culture positive and produced a total of 85 isolates. Monomicrobial and polymicrobial infections were observed from the collected grade 2 and 3 samples, respectively. Gram's staining and morphological analyses of the obtained bacterial colony demonstrated the presence of both Gram-positive and Gram-negative bacilli, Gram-positive cocci, and Gram-negative cocco-bacilli in the wounds of diabetic patients. The bacterial profiling of 85 isolates revealed the presence of Gram-negative bacteria such as Pseudomonas aeruginosa, Escherichia coli, Proteus spp, Acinetobacter spp, Enterobacter spp, Klebsiella pneumoniae, Citrobacter spp, K oxytoca, and Stenotrophomonas spp Gram-positive bacteria such as Staphylococcus aureus, Bacillus subtilis, Enterococcus faecalis, Corynebacterium spp, and Streptococcus dysgalactiae were also identified. The predominant microbial flora found in the collected samples were Staphylococcus aureus (38%) and P aeruginosa (23.2%), followed by B subtilis (21%) and Escherichia coli (18%) and other bacteria. Furthermore, the obtained antibiotic susceptibility assay data of DFU isolates have also confirmed the distribution of multiantibiotic-resistant bacteria in the wound site of diabetic patients. The findings of the present study suggest that there is a need for the discovery of novel drug(s) to alleviate antibiotic-resistant bacterial infections in DFU patients.

Abstract
Background Medicine-taking behaviour of people in Indonesia is particularly complex because of Indonesia's pluralistic health system, in which public and private medical services co-exist with traditional and alternative treatments. Objective This study aimed to explore medicine-taking behaviours of people with type 2 diabetes in Indonesia. Setting Rural and urban communities in East Nusa Tenggara and West Sumatera Provinces. Method Qualitative study with focus group discussions. Six focus groups, involving 45 diabetes patients, were conducted. The discussions were recorded and transcribed verbatim in the original language. The transcripts were translated into English and analysed for common themes. Main outcome measure People's medicine-taking behaviours after being diagnosed with diabetes. Results Medicine-taking behaviours of diabetes participants aligned with the concept of resistance to medicine taking and a therapeutic decision model. It varied based on individual lay evaluation processes. After being diagnosed, participants commonly took the prescribed medicines for some period. They then self-evaluated the effectiveness of the prescribed medicines. Based on the self-evaluation, patients either continued to take the prescribed medicines or made a variety of changes: they discontinued taking the prescribed medicines, combined or alternated prescribed medicines with traditional medicines, or occasionally took medicines they bought without prescription. Reasons mentioned by participants for choosing traditional medicines including perceived ineffectiveness or side effect of the prescribed-medicines. Long-term medicine taking burdened the participants as the notion of being fed up with taking medicines was frequently mentioned. Problems of inaccessibility of the prescribed-medicines also emerged. Conclusion Diabetes patients' medicine-taking behaviours and their reasons for decision-making need to be acknowledged to improve adherence to medicine. Health professionals should assist patients on how to evaluate effectiveness, manage side effects, and reduce the medicine-related burden.

Abstract
Diabetic foot ulcer (DFU) is a major complication of diabetes mellitus, major observations of DFU cases have reported on amputation of foot region, and microbial bioburden during DFU is a major cause that affects healing of the wound regions. Pathogenic microbes are routinely isolated from these wound regions, especially Staphylococcus, Pseudomonas, Klebsiella, and Escherichia coli have been reported, whereas higher prevalence of Pseudomonas species during chronic condition in the deeper part of the wound, when left untreated, leads to gangrene. Multiple drug-resistant Pseudomonas strains are a new threat because of their biofilm-forming ability, making it more potent and incurable. Acyl homoserine lactones (AHL) are a group of signaling molecules that can regulate biofilm growth, and Las and Rhl operon generally work in tandem to initiate biofilm formation by Pseudomonas species. These signaling molecules also initiate virulence factors that correlates upregulation of inflammatory responses, and AHL can be a therapeutic target in order to prevent the efficacy of multiple drug-resistant strains that form biofilm and also can be an alternative solution against control of multiple drug-resistant strains.

Abstract
Staphylococcus aureus is the most frequent pathogen causing diabetic foot infections. Here, we investigated the degree of bacterial virulence required to establish invasive tissue infections in diabetic organisms. Staphylococcal isolates from diabetic and non-diabetic foot ulcers were tested for their virulence in in vitro functional assays of host cell invasion and cytotoxicity. Isolates from diabetes mellitus type I/II patients exhibited less virulence than isolates from non-diabetic patients, but were nevertheless able to establish severe infections. In some cases, non-invasive isolates were detected deep within diabetic wounds, even though the strains were non-pathogenic in cell culture models. Testing of defined isolates in murine footpad injection models revealed that both low- and high-virulent bacterial strains persisted in higher numbers in diabetic compared to non-diabetic hosts, suggesting that hyperglycemia favors bacterial survival. Additionally, the bacterial load was higher in NOD mice, which have a compromised immune system, compared to C57Bl/6 mice. Our results reveal that high as well as low-virulent staphylococcal strains are able to cause soft tissue infections and to persist in diabetic humans and mice, suggesting a reason for the frequent and endangering infections in patients with diabetes.

Abstract
AIM To explore and synthesize evidence of the literature about healthcare professionals involved in the provision of diabetes management within an Indonesian context. BACKGROUND Indonesia is challenged to control the major burden of diabetes prevalence rate that requires a multidimensional approach with the aim to optimize existing health services by involving healthcare professionals who can promote access and provide diabetes management. METHODS This literature review, which is integrated with a scoping study framework, used the electronic databases including CINAHL, PubMed, Scopus and Web of Science to locate papers particular to the Indonesian context. From the total of 568 papers found, 20 papers were selected. RESULTS The literature review identified physicians, nurses, pharmacists, dieticians and diabetes educators as the providers of diabetes care and management in Indonesia. Collaborative management involving either interdisciplinary or intradisciplinary teams was mentioned in several papers. Internal challenges included limited skills and knowledge. External challenges included high patient volumes; a shortage of healthcare professionals and reduced funding. CONCLUSIONS Overcoming the challenges cannot be undertaken with a workforce dominated by any one single healthcare professional. Coordinating with the government to improve the implementation of different roles in diabetes management will improve patient outcomes and thus reduce the burden of diabetes. IMPLICATION FOR NURSING AND HEALTH POLICY Health policy reform should support nurses and other healthcare professionals in their professional development at all levels of health care. Policy makers can use the review findings to modify the current healthcare system to address key issues in workforce development; funding for services and medications; and fostering multidisciplinary care for diabetes management.

Abstract
Staphylococcus aureus bacteremia (SAB) is usually monomicrobial (M-SAB). We reviewed SAB in adults (≥18years old) over a 13year-period and compared polymicrobial (P-SAB) and M-SAB. We encountered 93 P-SAB among 1537 SAB cases (6.1%). The source distribution was comparable; however, source-specified differences were apparent. P-SAB was noted in 12/58 (20.7%) necrotizing soft tissue infections/sacral decubiti and foot gangrene vs. 1/122 (0.8%) cellulitis/abscesses (P<0.001), in 7/64 (10.9%) femoral intravascular catheters (IVC) vs.16/376 (4.3%) IVC in other sites (P=0.03) and 15/134 (11.2%) healthcare-associated pneumonia (HAP) vs. 1/33 (3.0%) community-associated cases (P=0.1). Methicillin-resistance frequency was similar but community-associated SCCmec types (IV/V) were infrequent (17.9% vs. 34.2%; P=0.04). P-SAB was associated with higher mortality (50.5% vs. 24.2%; P<0.001) across nearly all sources. In summary, P-SAB is infrequent, usually encountered in necrotizing soft tissue infections/decubiti, femoral IVC and possibly HAP. The actual incidence of S. aureus in these infections should be defined.

Abstract
Infection of foot ulcers is a common, often severe and costly complication in diabetes. Diabetic foot infections (DFI) are mainly polymicrobial, and Staphylococcus aureus is the most frequent pathogen isolated. The numerous virulence factors and toxins produced by S. aureus during an infection are well characterized. However, some particular features could be observed in DFI. The aim of this review is to describe the role of S. aureus in DFI and the implication of its toxins in the establishment of the infection. Studies on this issue have helped to distinguish two S. aureus populations in DFI: toxinogenic S. aureus strains (harboring exfoliatin-, EDIN-, PVL- or TSST-encoding genes) and non-toxinogenic strains. Toxinogenic strains are often present in infections with a more severe grade and systemic impact, whereas non-toxinogenic strains seem to remain localized in deep structures and bone involving diabetic foot osteomyelitis. Testing the virulence profile of bacteria seems to be a promising way to predict the behavior of S. aureus in the chronic wounds.

Abstract
BACKGROUND The aim of this study was to outline the patterns and management of diabetic foot ulcer (DFU) and compare our experience with other published data. PATIENTS AND METHODS All consecutive patients admitted to Al-Jala Hospital with diabetic foot from June, 2008 to May, 2013 were reviewed retrospectively. RESULTS A total of 542 patients were studied, Wagner's grade III ulcers were the most prevalent (31%), followed by grade II (25%). About 10% of patients underwent major amputations and 24.2% underwent minor amputations. The amputation rate was 34%, and the mortality rate was 2%. CONCLUSION Diabetic foot infections cause significant morbidity and mortality among patients with diabetes in Benghazi. There is a need to establish a diabetic foot clinic in Benghazi with a multidisciplinary team to reduce the rates of hospital admission and amputation, as well as hospital stay duration.
