Delayed wound healing is a Type 2 diabetes mellitus (DM) complication caused by hyperglycemia, systemic inflammation, and decreased blood microcirculation. Skeletal muscles are also affected by hyperglycemia, resulting in reduced blood flow and glucose uptake. Low Magnitude High Frequency Vibration (LMHFV) has been proven to be beneficial to muscle contractility and blood microcirculation. We hypothesized that LMHFV could accelerate the wound healing of n5-streptozotocin (n5-STZ)-induced DM rats by enhancing muscle activity and blood microcirculation...

Soon after epidermal growth factor (EGF) discovery, some in vivo models appeared demonstrating its property to enhance cutaneous wound healing. EGF was the first growth factor (GF) introduced in the clinical arena as a healing enhancer, exerting its mitogenic effects on epithelial, fibroblastoid, and endothelial cells via a tyrosine kinase membrane receptor. Compelling evidences from the 90s documented that, for EGF, locally prolonged bioavailability and hourly interaction with the receptor were necessary for a successful tissue response...

Objective: Diabetes affects more than 29 million individuals in the United States, resulting in healthcare costs approaching $245 billion. Approximately 15% of these individuals will develop a chronic, non-healing foot ulcer (diabetic foot ulcer [DFU]) that, if untreated, may lead to amputation. The current treatments for DFU are expensive, have significant side-effects, and often result in non-compliance. A new topical treatment is described that accelerates cutaneous wound repair and is disease modifying by targeting underlying aberrant diabetic pathways...

Impaired wound healing accompanies severe cell apoptosis in diabetic patients. Tissue Inhibitor of Metalloproteinases-1 (TIMP-1) was known to have effects on promoting growth and anti-apoptosis for cells. we aimed to determine the actual levels of TIMP-1 and cell apoptosis in: 1) the biopsies of diabetic and non-diabetic foot tissue; 2) the human fibroblasts with or without treatments of Advanced Glycation End Products (AGEs). Next, in both human fibroblasts and the animal model of diabetic rats, to determine the improved levels of cell apoptosis and wound healing after the treatments of either active protein of TIMP-1 or in vivo expression of gene therapy vector-mediated TIMP-1...

Diabetes is a prevalent disease endangering human health, while diabetic foot disease (DF) is one of the most severe complications of diabetes. Mesenchymal stem cells (MSCs) have been used in DF treatment, taking advantage of the differentiation potential of MSCs into endothelial cells and their production and secretion of trophic factors like vascular endothelial growth factor (VEGF). Molecular modification of MSCs to improve their therapeutic effects has been recently applied in treating other diseases, but not yet in DF...

OBJECTIVE: Osteopontin (OPN) is abundantly expressed during tissue repair, acting as a powerful chemokine that recruits inflammatory cells such as neutrophils, macrophages, and Langerhans cells. The role of OPN in chronic wounds has not been explored. In this study, we assess the expression levels of OPN in chronic wounds to assess its potential contribution to the exacerbated inflammation seen in chronic ulcers, which is thought to contribute to poor healing. METHODS: This retrospective study included archived biopsies of chronic wounds from several aetiologies...

Remote ischemic conditioning involves the use of a blood pressure cuff or similar device to induce brief (3-5 min) episodes of limb ischemia. This, in turn, seems to activate a group of distress signals that has shown the potential ability to improve healing of the heart muscle and other organ systems. Until recently, this has not been tested in people with diabetic foot ulcers. The purpose of this review was to provide background on remote ischemic conditioning and recent data to potentially support its use as an adjunct to healing diabetic foot ulcers and other types of tissue loss...

Mantle cell lymphoma (MCL) is a rare type of non-Hodgkin lymphoma that commonly affects extranodal sites. The most commonly affected sites are the bone marrow, gastrointestinal tract, Waldeyer's ring, lung, and pleura. We report the case of an 80-year-old diabetic male, in MCL remission, who presented with a small dome-shaped nodule on his calf and an ipsilateral second digit non-healing ulceration after a traumatic fall. Despite surgical and conservative treatment, the wound worsened, resulting in histopathologic examination, which confirmed the presence of lymphocytes, indicating MCL relapse...

Diabetes mellitus is one of the most challenging epidemics facing the world today, with over 300 million patients affected worldwide. A significant complication associated with diabetes is hyperglycemia, which impairs wound healing. The rise in the diabetic patient population in recent years has precipitated an increase in the incidence and prevalence of chronic diabetic wounds, most commonly the diabetic foot ulcer. Although foot ulcers are difficult to treat due to their complicated pathology, outcomes have improved with the development of increasingly sophisticated biomaterials that accelerate healing...

In this randomized controlled trial, diabetic patients with foot ulcers (Wagner grades 1 and 2) were randomly assigned to conventional therapies for diabetic foot ulcer plus topical propolis ointment (5%; twice daily) or conventional therapies alone. The process of ulcer healing was observed during 4 weeks and compared between the two groups regarding the size, erythema, exudates, white blood cell (WBC) count and erythrocyte sedimentation rate (ESR). The process of ulcer size reduction during the four-week period of study was significantly different between the groups...

Diabetes is a serious disease with severe side effects and comorbidities. Diabetic foot with its chronic non-healing ulcers, or diabetic food ulcers (DFU) as they are commonly called, can be devastating, even leading to amputation. Many therapies exist to assist and improve wound healing. One exciting discovery is the use of negative pressure wound therapy (NPWT) as an adjunct to standard treatment. Few studies have substantively explored the molecular mechanisms of NPWT and why we see improved wound healing, a concept that demands more research...

Diabetic foot ulcers may result in loss of an extremity and may even lead to mortality. The use of comprehensive foot care programs which include early screening and evaluation of problems, foot care education, preventive therapy and referral to specialists has been shown to reduce amputation rates by 49-85 [percent]. A 51-year-old woman with Type 2 diabetes under surveillance for nine months was referred from the emergency department. She presented with an entirely inflamed right foot with ulcer covering two-thirds proximal of the foot for 30 days' duration...

BACKGROUND: Type II diabetes is a chronic health condition which is associated with skin conditions including chronic foot ulcers and an increased incidence of skin infections. The skin microbiome is thought to play important roles in skin defence and immune functioning. Diabetes affects the skin environment, and this may perturb skin microbiome with possible implications for skin infections and wound healing. This study examines the skin and wound microbiome in type II diabetes. METHODS: Eight type II diabetic subjects with chronic foot ulcers were followed over a time course of 10 weeks, sampling from both foot skin (swabs) and wounds (swabs and debrided tissue) every two weeks...
