RESUMEN
OBJECTIVE: The objective of this study is to assess the efficacy of decompression nursing based on biomechanical principles in managing recurrent diabetic plantar ulcers. METHODS: Sixty-seven patients experiencing recurrent diabetic plantar ulcers who sought medical attention at Huadong Hospital Affiliated to Fudan University between January 2021 and December 2022 were selected as participants for this study. The participants underwent biomechanics-based decompression nursing. We compared pre-intervention and post-intervention data to assess the differences in relevant observational indexes. RESULTS: Post-intervention, patients showed significant improvements in foot comfort scores and adherence to pressure reduction behavior compared with their pre-intervention status, with statistical significance (P < 0.05). The intervention was effective in 41 cases (61.19%), with 18 cases (26.87%) showing improvement and 8 cases (11.94%) deemed ineffective, culminating in an overall efficacy rate of 88.06%. All 67 patients achieved complete ulcer healing within an average duration of 58.63 ± 18.13 days, without any recorded recurrences. CONCLUSION: Biomechanics-based decompression nursing demonstrates effective facilitation of wound healing, yielding expeditious recovery, enhanced comfort, and a reduced incidence of recurrence.
RESUMEN
Diabetic foot ulcers were a significant complication of diabetes and were accompanied by delayed wound healing. To compare the effect of topical application electrospun poly (L-lactide-co-caprolactone) and formulated porcine fibrinogen (PLCL/Fg) dressing with alginate dressing when treating diabetic foot ulcers (DFUs). A single-center, prospective, randomized, patient-blinded clinical trial was conducted from July 1, 2023, to December 26, 2023. The clinical trial registration was completed on August 28, 2023 (ClinicalTrials.gov Identifier: NCT06014437). The eligible patients with DFUs of 1-20 cm2 present for at least 1 month and with Wagner grade 1 or 2. They were randomized 1:1 to receive PLCL/Fg or alginate dressing. Participants received PLCL/Fg dressing 1-3 times per week or alginate dressing 3 times per week for 12 weeks. A total of 52 patients (33 men [63.5 %]; mean [SD] age, 63.1 [11.9] years; mean [SD] diabetes time, 8.3 [4.6] years) with DFUs were assessed for this study. The DFUs classified as Wagner grade 1 or 2 (mean [SD] ulcer area, 3.8 [3.2] cm2) were randomized to receive either the PLCL/Fg dressing (n = 26) or the alginate dressing (n = 26) for as long as 12 weeks. In this study, the incidence of complete healing included 22 patients (91.7 %) in the PLCL/Fg group and 14 (63.6 %) in the alginate group during the 12-week treatment period (P = 0.003). The treatment-related adverse events that occurred were 5 (20.8 %) in the PLCL/Fg group and 4 (18.1 %) in the comparator group. In this randomized clinical trial, PLCL/Fg dressing showed beneficial effects in DFUs treatment of wound surface reduction and regulating the wound microenvironment.

BACKGROUND: Silica gel fiber (SGF) dressing is a novel patch for wound healing. OBJECTIVE: To compare the efficacy and safety of SGF dressing with alginate dressing in local treatment of venous leg ulcers. METHODS: Patients with venous leg ulcers who had undergone effective treatment of venous hypertension and debridement were randomized to receive wound care with either SGF dressing or alginate dressing for 4 weeks. Wounds were assessed weekly during the first 4 weeks and then every 2 weeks until the 8th week. The primary endpoint was the efficacy rate. Secondary endpoints included ulcer area reduction rate, healing rate, frequency of dressing changes, pain score, patient satisfaction, and treatment-related adverse events. RESULTS: A total of 130 patients were enrolled, 67 treated with SGF and 63 with alginate dressing, and the efficacy rates were 89.6% (SGF group) and 84.1% (alginate group). SGF induced a higher "no pain" rate than alginate at week 2 (61.4% vs 43.5%) and week 3 (67.6% vs 53.1%), and a higher "highly satisfied" rate at week 4 (83.3% vs 78.8%) and week 8 (75% vs 59.1%). Markedly fewer dressing changes were required in the SGF group. CONCLUSIONS: SGF dressing is non-inferior to alginate dressing in treating venous leg ulcers. It even substantially decreased the frequency of dressing changes when compared with alginate dressing.
