Within the APG group, individuals with DF received weekly APG treatment. In the non-APG group, DF patients received daily dressing changes. Flow cytometry quantified the proportion of endothelial progenitor cells (EPCs) in peripheral blood on days 0 and 10. The diabetic rat model was induced using Streptozotocin. Two circular skin wounds were created on the backs of rats. The normal glucose group received daily dressing changes on the wound. In the diabetic group, the left wound underwent daily dressing changes, whereas the right wound was treated with APG once a week. CD34 levels were tested 7 days after the skin damage. The levels of glutathione peroxidase 4 (GPX4), Nuclear Receptor Coactivator 4 (NCOA4), Light chain 3 (LC3), and Masson staining were quantified on 14 days. The wound area and wound healing rate were separately measured at 0 and 14 days after the injury, regardless of DF patients or diabetic rats. <b>Results:</b> The wound healing rate was higher in the APG group than in the non-APG group, regardless of DF patients or diabetic rats. The APG group had a greater ΔEPCs% in DF patients than the non-APG group. Regarding rat experiment, the APG group exhibited lower levels of NCOA4, and LC3 expressions and a shorter wound healing time. However, the APG group showed higher levels of CD34 expression, GPX4 protein, and collagen fibers than the non-APG group. <b>Conclusions:</b> Autologous platelet-rich gel accelerated the wound healing rate in diabetic populations and rats. Autologous platelet-rich gel promoted EPCs counts, collagen fiber volume, and vessel numbers. Autologous platelet-rich gel decreased LC3 and NCOA4 expression, but increased GPX4 protein expression.

Wounds that fail to heal satisfactorily may result in the amputation of the organ. In this research work, cinnamon oil (CO) and aloe vera (AV) that have been traditionally used as antibacterial agents are combined in a unique gel (COVA) and its antibacterial activity has been evaluated through <i>in vitro</i> and <i>in vivo</i> studies. Antibacterial activity was measured through disk diffusion and agar dilution method against <i>Pseudomonas aeruginosa</i> and <i>Staphylococcus aureus</i>. To check antibacterial and wound healing activity, diabetic excision wound healing rat model was used. Wound closure, wound contraction, tissue hydroxyproline content, antioxidant capacity (TAC), and malondialdehyde (MDA) level were monitored. The minimum inhibitory concentrations of CO + AV for bacterium <i>P. aeruginosa</i> and <i>S. aureus</i> were 100 and 200 µg/ml, respectively. After 14 days, the wounds covered with COVA therapy reached to nearly full wound closure (79% wound contraction) compared to control. The collagen content and level of TAC increased significantly (<i>P</i> < 0.05) in treated groups; therefore, 25% fast healing was observed in wounds treated with CO and AV gel combined. Reduced levels of tissue MDA were observed in all treated groups and specially wound covered with COVA (0.43 mM/mg in control vs 0.25 mM/mg in COVA). Histopathological examination also supported the outcomes. Significantly elevated increase in the level of hydroxyproline was found in rats of COVA treatment group (37.1 ± 0.44).

An increasingly emerging cause of CNO is the use of oncological drugs which can cause neuropathic damage. The use of these therapies dramatically increased in recent years. CNO leads to a progressive degeneration of the foot's joints and to bone destruction and resorption which ends in deformities. These alterations in the foot's anatomy determine a high risk of ulceration, infection, and osteomyelitis. The superimposition of osteomyelitis on CNO increases the risk of major amputation, already high in patients suffering either from only CNO or osteomyelitis alone. We report the case of a 61-year old nondiabetic woman affected by CNO as a consequence of antiblastic therapy for breast cancer and the subsequent overlap of osteomyelitis, confirmed by magnetic resonance imaging.
