Role and effect of vein-transplanted human umbilical cord mesenchymal stem cells in the repair of diabetic foot ulcers in rats.
In this study, a rat DFU model was used to simulate the pathophysiology of clinical patients and to investigate the localization of human umbilical cord mesenchymal stem cells (hUC-MSCs) after intravenous transplantation and its role in DFU healing, so as to evaluate the potential of hUC-MSCs in the treatment of DFU. The diabetic rat model was established by streptozotocin injection, which was used to create full-thickness foot dorsal skin wounds to mimic DFU by a 6-mm skin biopsy punch and a Westcott scissor. The hUC-MSCs were transplanted through femoral vein, and the ulcer cicatrization situation and the fate of hUC-MSCs were evaluated. Our data suggest that intravenously transplantated hUC-MSCs have the ability to migrate and locate to the wound tissue and are helpful to wound healing in DFU rats, partly by regulating inflammation, trans-differentiation and providing growth factors that promote angiogenesis, cell proliferation and collagen deposition. Herein, we demonstrate that hUC-MSC transplantation is able to accelerate DFU healing in rats and transplantation of exogenous stem cells may be a potential strategy for clinical application in DFUs.

Diabetic foot ulcer (DFU) is a serious complication of diabetes mellitus. Antibiotic-resistant Staphylococcus aureus is frequently isolated from DFU infections. Bacteriophages (phages) represent an alternative or...
Authors: Zizzi CF, Pellicano R, Biancone L Abstract A number of studies has confirmed that the epidemiology of Helicobacter pylori (H. pylori) is changing worldwide, with a decrease especially in developed Countries. Nevertheless, since this Gram-negative bacterium infects almost 50% of the world's population, it remains a global problem. Beyond its role in the pathogenesis of the main gastroduodenal diseases, including gastritis, peptic ulcer and gastric cancer, H. pylori has been suspected to be involved in several extra-gastroduodenal disorders. Patients with chronic kidney disease (CKD) present gastric mucosal ...
Conclusions: The majority of CHC patients had comorbidities; almost all patients took multiple prescribed medications, the number of which increased with age, and significant DDI risk was present in 97% of this Korean patient cohort. Comorbidities and comedication profiles should be considered during DAA therapy. PMID: 32616682 [PubMed - as supplied by publisher]
This study demonstrated that periodontitis was associated with an increased risk of chronic gastritis/peptic ulcer. These findings provide additional evidence for an association between periodontitis and chronic gastritis/peptic ulcer.

Conclusions: Staphylococcus aureus, Propionibacterium acnes, and Pseudomonas aeruginosa keratitis with or without endophthalmitis represent the most common indication for ocular enucleation/evisceration in patients with microbial keratitis in a tertiary referral center in Hungary. The incidence of enucleation and evisceration related to mycotic keratitis does not seem to have increased within the last decade. Most frequent preexisting systemic diseases in cases of enucleation and evisceration are hypertension, cardiac disease, diabetes mellitus, and rheumatoid arthritis. PMID: 32509342 [PubMed]
CONCLUSION: The study revealed that the cost of DFU could show variability in relation to countries' level of development. We highlighted similar studies in other countries; the major factors of total expenses were length of hospitalisation, medication prescription and use of surgery.

Population ageing and changes in lifestyle behaviors enhance the world ’s population with diabetes, which continue growing. The prevalence of diabetes mellitus has increased substantially and has reached 8.3% in 2013, which corresponds to 382 million patients globally; this number is expected to rise to 592 million by 2035 . Lower extremity amputation (LEA) is an adverse outcome of diabetic foot infection and results from diabetic microvascular complications due to an end-stage disease process, such as chronic nonhealing foot ulcer (e.g., organ failure of the skin, failure of the biomechanics of the foot as a unit...
This study aimed to use high-throughput 16S rRNA gene sequencing to investigate the changes in foot skin microbiome of patients with diabetes mellitus from a single center in China. MATERIAL AND METHODS Fifty-two participants were divided into 4 study groups: healthy controls (n=13); patients with short-term diabetes (10 years; n=13). Swabs were analyzed from the intact skin of the foot arch using high-throughput 16S ribosomal RNA sequencing. RESULTS Microbiome phylogenic diversity varied significantly between the study groups (whole tree, P
CONCLUSION: The foot care K&B scores of patients with diabetes were low to moderate levels, particularly on items that pertained to self-foot examination, prompt treatment of foot problems, and regular foot inspection by professionals. Individuals with high risk of developing foot complications did not score higher on the K&B questionnaire. These data suggest there is need for improvement in instruction and patient uptake and application of knowledge. We recommend further study on the effectiveness of the delivery of foot care education based on foot risk stratification, and the implications of foot ulcer prevention in community settings.
