A diabetic foot ulcer is an open wound that can become sore and frequently occurs in diabetic patients. Alginate has the ability to form a hydrophilic gel when in contact with a wound surface in diabetic patients. Xanthones are the main compounds of mangosteen rind and have antibacterial and anti-inflammatory properties. The purpose of this research was to evaluate the wound healing and antioxidants assay with a combination of alginate from S. ilicifolium and mangosteen rind combination extracts on a diabetic mice model. The characterization of alginate was carried out by size exclusion chromatography with multiple angle laser light scattering (SEC-MALLS) and thermogravimetric analysis (TGA). The M/G ratio of alginate was calculated by using proton nuclear magnetic resonance (1H NMR). The antioxidant activity of mangosteen rind and the combination extracts was determined using the DPPH method. The observed parameters were wound width, number of neutrophils, macrophages, fibrocytes, fibroblasts, and collagen densities. The 36 male mice were divided into 12 groups including non-diabetic control (NC), diabetes alginate (DA), alginate–mangosteen (DAM), and diabetes control (DC) groups in three different groups by a histopathology test on skin tissue. The treatment was carried out for 14 days and mice were evaluated on Days 3, 7, and 14. The SEC-MALLS results showed that the molecular weight and dispersity index (Ð) of alginate were 2.77 × 104 Dalton and 1.73, respectively. The M/G ratio of alginate was 0.77 and described as single-stage decomposition based on TGA. Alginate, mangosteen rind extract, and their combination were divided into weak, medium, and strong antioxidant, respectively. The treatment of the DA and DAM groups showed a decrease in wound width and an increase in the number of fibrocytes, fibroblasts, and macrophages. The number of neutrophils decreased while the percentage of collagen densities increased for all the considered groups.

Diabetic foot ulcers (DFUs) are a serious complication in diabetic patients and lead to high morbidity and mortality. Numerous dressings have been developed to facilitate wound healing of DFUs. This study investigated the wound healing efficacy of silver-releasing foam dressings versus silver-containing cream in managing outpatients with DFUs. Sixty patients with Wagner Grade 1 to 2 DFUs were recruited. The treatment group received silver-releasing foam dressing (Biatain® Ag Non-Adhesive Foam dressing; Coloplast, Humlebaek, Denmark). The control group received 1% silver sulfadiazine (SSD) cream. The ulcer area in the silver foam group was significantly reduced compared with that in the SSD group after four weeks of treatment (silver foam group: 76.43 ± 7.41%, SSD group: 27.00 ± 4.95%, p < 0.001). The weekly wound healing rate in the silver foam group was superior to the SSD group during the first three weeks of treatment (p < 0.05). The silver-releasing foam dressing is more effective than SSD in promoting wound healing of DFUs. The effect is more pronounced in the initial three weeks of the treatment. Thus, silver-releasing foam could be an effective wound dressing for DFUs, mainly in the early period of wound management.

Diabetes is previously known as the disease of the rich people, but now there is  no partiality between the rich and poor and it has become the third leading cause of  death. Diabetic Mellitus (DM) is a metabolic issue that is characteristics by  chronic hyperglycemia; it is a typical and conceivably persistent disease. The  aims of the present study to assess the effectiveness of insulin dressing of the diabetic foot ulcer among diabetic patients. A quasi-experimental research design with  purposive sampling technique was adopted to conduct a study among 30 diabetic foot ulcer patients. Demography data was collected and wound was measured and insulin dressing was done. After one week the wound was measured. Confidentiality was maintained throughout the procedure. The collected data were analyzed by using descriptive and inferential statistics. Among 30 samples pretest mean score of wound healing among patients with diabetic foot ulcer in the topical insulin dressing was 2.67±0.66 and the post test mean score was 1.43±0.57. The calculated paired ‘t’ test  value of t = 15.703 was found to be statistically highly significant at p<0.001 level.  The above finding clearly infers that topical insulin dressing to patients with diabetic foot ulcer had significant effect which resulted in the improvement in the level of  wound healing among patients with diabetic foot ulcer.

Diabetes mellitus is a group of metabolic disorders characterized by high blood-glucose levels over a prolonged period that causes complications when an open wound is present. Alginate is an antioxidant and a good absorbent of exudates. Okra fruit contains flavonoids that can act as antioxidants. The antioxidant properties of extracts combination reduce blood-glucose levels significantly to accelerate the activities of wound-healing processes on diabetic mice. Alginate was characterized by Size Exclusion Chromatography-Multiple Angle Laser Light Scattering (SEC-MALLS), thermal stability and Proton Nuclear Magnetic Resonance (1H-NMR). The evaluation of wound healing on 36 male mice were divided into 12 groups including normal control (NC), diabetics control (DC), alginate (DA) and alginate–okra (DAO) groups in three different times by histopathology test on skin tissue. The results of SEC-MALLS analysis showed that alginate as single and homogeneous polysaccharide. The 1H-NMR spectrum showed that the mannuronate/guluronate ratio of the used alginate was 0.91. Alginate, okra fruit extract and their combination were classified as moderate and strong antioxidants. The numbers of fibrocytes, fibroblasts, collagen densities had significantly increased from three to seven days. In contrast, wound width, neutrophil, macrophages had significantly decreased at 14 days. The administration of extracts combination increased the re-epithelization of the wound area and wound-healing process on diabetic mice.

While virulence factors and the biofilm-forming capabilities of microbes are the key regulators of the wound healing process, the host immune response may also contribute in the events following wound closure or exacerbation of non-closure. We examined samples from diabetic and non-diabetic foot ulcers/wounds for microbial association and tested the microbes for their antibiotic susceptibility and ability to produce biofilms. A total of 1074 bacterial strains were obtained with staphylococci, Pseudomonas, Citrobacter and enterococci as major colonizers in diabetic samples. Though non-diabetic samples had a similar assemblage, the frequency of occurrence of different groups of bacteria was different. Gram-negative bacteria were found to be more prevalent in the diabetic wound environment while Gram-positive bacteria were predominant in non-diabetic ulcers. A higher frequency of monomicrobial infection was observed in samples from non-diabetic individuals when compared to samples from diabetic patients. The prevalence of different groups of bacteria varied when the samples were stratified according to age and sex of the individuals. Several multidrug-resistant strains were observed among the samples tested and most of these strains produced moderate to high levels of biofilms. The weakened immune response in diabetic individuals and synergism among pathogenic micro-organisms may be the critical factors that determine the delicate balance of the wound healing process.

AbstractObjective. The high amputation rates from diabetic foot ulcer (DFU) in Nigeria and prolonged hospitalization due to poor wound healing is a source of concern. Furthermore, factors that affect wound healing of DFUs have not yet been well studied in Nigeria, whereas knowing these factors could improve DFU outcomes. Therefore, the objective of this study was to determine the factors that are associated with the wound healing in patients hospitalized for DFU.Methods. The Multi-Center Evaluation of Diabetic Foot Ulcer in Nigeria (MEDFUN) was an observational study involving 336 diabetic patients hospitalized for DFU and managed by a multi-disciplinary team until discharge or death. Demographic, clinical, and biochemical characteristics were documented. Test statistics used were chi square, t-test, univariate, and multivariate logistic regression. The study endpoints were ulcer healing, LEA, duration of hospitalization, and mortality. Here we present data on wound healing.Results. The mean ± SD age was 55.9±12.5 years. Univariate predictors of wound healing were ulcer duration more than 1 month prior to hospitalization (p<0.001), peripheral arterial disease (PAD) (p<0.001), foot gangrene (p<0.001), Ulcer grade ≥3 (p=0.002), proteinuria (p=0.005), anemia (p=0.009), renal impairment (p=0.021), glycated hemoglobin ≥7% (0.012), and osteomyelitis (p<0.001). On multivariate regression, osteomyelitis was the strongest independent predictor of wound healing after adjusting for all other variables (OR 0.035; 95% CI 0.004–0.332). This was followed by PAD (OR 0.093; 95% CI 0.028–0.311), ulcer duration >1 month (OR 0.109; 95% CI 0.030–0.395), anemia (OR 0.179; 95% CI 0.056–0.571).Conclusion. Presence of osteomyelitis, duration of ulcer greater than 1 month, PAD, Wagner grade 3 or higher, proteinuria, presence of gangrene, anemia, renal impairment, and HbA1c ≥7% were the significant predictors of wound healing in patients hospitalized for DFU. Early identification and prompt attention to these factors in a diabetic foot wound might significantly improve healing and reduce adverse outcomes such as amputation and death.

Abstract In diabetic patients, the presence of neuropathy, peripheral vascular diseases and ischemia, leads to the formation of foot ulcerations with a higher risk of infection because the normal response to bacterial infection is missing. In the aim to control and treat Diabetic Foot Ulcerations (DFUs), wound dressings able to absorb exudate, to prevent infections and to promote wound healing, are needed. For this reason, the aim of the present research was to synthetize a biocompatible hydrogel composed by Carboxymethylcellulose (HyDrO-DiAb) loaded with Silver nanoparticles (AgNPs) for the treatment of diabetic foot ulcer. In this study, AgNPs were obtained by a green synthesis and, then, were dissolved in CMC hydrogel that, after freeze drying process become a flexible and porous structure. The in vitro and in ex-vivo wound healing activity of the obtained HyDrO-DiAb hydrogel was evaluated.

The number of people with diabetes is expected to reach 592 million in the year 2035. Diabetic foot lesions are responsible for more hospitalizations than any other complication of diabetes. The aims of this study were to examine for the first time a new biocompatible and biodegradable tridimensional collagen-based matrix, GBT013, in humans for diabetic foot ulcer wound healing and to evaluate its ease of use to better define a protocol for a future clinical trial. Seven adult patients with a diabetic foot ulcer of grade 1A to 3D (University of Texas Diabetic Wound Classification) were treated using GBT013, a new collagen-based advance dressing and were monitored in two specialized foot care units for a maximum of 9 weeks. Five of seven wounds achieved complete healing in 4 to 7 weeks. Nonhealed ulcers showed a significant reduction of the wound surface (&gt;44%). GBT013 was well tolerated and displayed positive wound healing outcomes as a new treatment strategy of chronic foot ulcers in diabetic patients.

Diabetic foot ulcer (DFU) is a combination of neuropathy and various degrees of peripheral vasculopathy in diabetic patients resulting in lower extremity infection, ulcer formation, and deep-tissue necrosis. The difficulty of wound healing in diabetic patients is caused by a high glucose environment and various biological factors in the patient. The patients’ skin local microenvironment changes and immune chemotactic response dysfunction. Wounds are easy to be damaged and ulcerated repeatedly, but difficult to heal, and eventually develop into chronic ulcers. DFU is a complex biological process in which many cells interact with each other. A variety of growth factors released from wounds are necessary for coordination and promotion of healing. Fibroblast growth factor (FGF) is a family of cell signaling proteins, which can mediate various processes such as angiogenesis, wound healing, metabolic regulation and embryonic development through its specific receptors. FGF can stimulate angiogenesis and proliferation of fibroblasts, and it is a powerful angiogenesis factor. Twenty-three subtypes have been identified and divided into seven subfamilies. Traditional treatments for DFU can only remove necrotic tissue, delay disease progression, and have a limited ability to repair wounds. In recent years, with the increasing understanding of the function of FGF, more and more researchers have been applying FGF-1, FGF-2, FGF-4, FGF-7, FGF-21 and FGF-23 topically to DFU with good therapeutic effects. This review elaborates on the recently developed FGF family members, outlining their mechanisms of action, and describing their potential therapeutics in DFU.

Diabetic foot ulcer (diabetic foot ulcer) is an injury entering through the profound vascular and collagenous (dermis) layers of the skin in diabetic patients. Helpless information by walking care and helpless foot care rehearses were distinguish as significant danger factors for foot issues in diabetes. The principle target of the investigation was to survey the effectiveness of topical insulin dressing versus saline dressing and analyze the degree of diabetic injury healing. Quasi-experimental with comparative research design was embraced for the investigation. Convenience sampling technique was utilized to choose 60 examples. Structured interview was used to collect background variable and Wagner diabetic wound assessment scale for assessing diabetic wound. The diabetic wound was dressed with topical insulin dressing and normal saline dressing for 6 days. The calculated paired 't' test value of t = 15.703 was found to be statistically highly significant at p<0.001 level whereas the calculated paired 't' test value of t = 3.247 was found to be statistically highly significant at p<0.01 level. There was significant that the topical insulin dressing is the more effective and improving the level of wound healing than normal saline dressing.

Diabetic foot ulcer is one of the major complications among diabetic patients. Several studies have shown that the extract of Teucrium polium (T. polium) is effective in the treatment of diabetic and non-diabetic wounds, as well as burn wounds. The aim of current study was to assess the wound healing activity of T. polium extract ointment in diabetic rats. Sixty-four male Wistar rats were induced diabetes with alloxan injection (125 mg/kg) and surgical wound induced. The rats were divided into 8 groups of eight rats each: control group, eucerin group, phenytoin group, 2%, 3%, 4%, 5% and 10% T. polium groups. The ointment was dressed on the wound twice a day. The process of wound healing was screened by macroscopy and digitalization on days 14 and 21 and until complete wound healing. There was no infection in the wounds of rats in any groups. The process of wounds healing of the 2%, 3%, 4%, 5%, and 10% T. polium ointments, with phenytoin ointment and base ointment (eucerin) on day 14 and 21, showed that the significant difference between the treatment groups with 4% (P = 0.003), 5% (P = 0.001), 10% (P = 0.001) T. polium ointment and phenytoin ointment group (P = 0.001) compared to eucerin group. The results of this study showed that T. polium extract ointment with a 10% ointment accelerates the wound healing process in diabetic rats and is comparable to the phenytoin group.
