Effects of evidence-based care on diabetic foot ulcers: A meta-analysis.

This analysis systematically reviewed the efficacy of evidence-based care on diabetic foot ulcers. A computerised literature search was conducted for randomised controlled studies (RCTs) of evidence-based care interventions for the treatment of diabetic foot ulcers using the PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), China Biomedical Literature Database (CBM) and Wanfang databases from the date of inception of each database to June 2023. The articles were independently screened, data were extracted by two researchers, and the quality of each study was assessed using the Cochrane bias assessment tool. Meta-analysis of the data was performed using RevMan 5.4 software. Twenty-five RCTs with a total of 2272 patients were included. Meta-analysis showed that, compared with other care methods, evidence-based care significantly improved the treatment efficacy of diabetic foot ulcers (odds ratio: 3.91, 95% confidence interval [CI]: 2.76 to 5.53, p < 0.001) and significantly reduced their fasting plasma glucose (mean difference [MD]: -1.10, 95% CI: -1.24 to -0.96, p < 0.001), 2-h postprandial glucose (2hPG) (MD: -1.69, 95% CI: -2.07 to -1.31, p < 0.001) and glycated haemoglobin (HbA1c) (MD: -0.71, 95% CI: -0.94 to -0.48, p < 0.001). Evidence-based care intervention is effective at reducing FPG, 2hPG and HbA1c levels and improving treatment efficacy in patients with diabetic foot ulcers.

Spectroscopic Characterization of a Polycaprolactone-Chitosan Electrospun Scaffold Modified with Photocatalytic TiO2 Nanoparticles for Improved Wound Healing: A Complete In Vivo Evaluation.

In the current study, we hypothesized that the electrospun scaffold chitosan (CS)/polycaprolactone (PCL)/titanium dioxide (TiO2) could be prepared by combining CS, PCL, and TiO2 nanoparticles (TiO2 NPs) using an electrospinning technique for wound dressing applications. The CS/PCL/TiO2 electrospun scaffold was prepared and characterized by UV-Vis, SEM, TEM, FTIR, and XRD analyses. Based on the UV-Vis analysis, the incorporation of CS/PCL on the surface of TiO2 NPs affected their optical properties. Further, CS/PCL and CS/PCL/TiO2 were found to have uniform distribution in fiber diameter with no bead morphology, as confirmed by SEM. The XRD spectrum of the CS/PCL/TiO2 revealed that the TiO2 NPs were adequately mixed with the CS/PCL solution, exhibiting the planes of TiO2 peaks (112), (105), (204), (116), and (301), which aligned well with the lattice structure. The antibacterial activity of CS/PCL/TiO2 against Staphylococcus aureus and Escherichia coli was evaluated using the zone of inhibition method. By testing the cytocompatibility of CS/PCL/TiO2 in vitro, this dressing was found to have a less toxic nature. In addition, In Vivo wound healing studies showed that the dressing prepared with the CS/PCL/TiO2 electrospun scaffold improved wound healing compared to that prepared with CS/PCL alone. The above results strongly support the use of CS/PCL/TiO2 electrospun scaffold as an effective dressing for wound healing.
