Background: Diabetic foot syndrome is a common complication of diabetes mellitus, and its incidence is increasing due to increasing rates of overweight and an aging population. Negative pressure wound therapy has been shown to improve wound healing. This study aimed to analyze the efficacy of this therapy compared with conventional treatments in patients with diabetic foot ulcers. Methods: A systematic search was conducted in the following databases: PubMed, SCOPUS, CINAHL, and the Cochrane Library, and the methodological quality was assessed using the Rob2 scale. This meta-analysis was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Results: A total of 11 clinical trials involving 1117 subjects. The primary outcome was efficacy, which was measured by the complete healing rate, wound size, time to granulation tissue formation, adverse effects, amputations, hospital stay, and cost. This study demonstrated that this therapy improves healing (OR= −10.39, 95% CI [−14.22, −6.57]) and reduces wound size (OR = −4.11, 95% CI [−7.83, −0.39]) while potentially lowering overall costs. Conclusions: Limitations include heterogeneity and different variables measured in studies. Additionally, there were differences among the trials due to the lack of blinding. Although no significant differences were found in amputations or infections, this therapy reduces pain and decreases the use of antibiotics and analgesics. Its use requires individual and expert assessment to maximize its benefits.

BACKGROUND Anxiety can influence the intensity of postoperative pain, anesthesia and the need for analgesia. Likewise, proper anxiety management can reduce hospital stays. Therefore, it is important to review the actions of nursing professionals and estimate the effect size of nursing interventions to reduce anxiety in the pre- and postsurgical processes. OBJECTIVE the objective of this study is to analyze the effectiveness of preoperative motivational interviews by nursing to reduce pre- and postoperative anxiety and postoperative pain after surgery. METHODS A systematic review was carried out according to the PRISMA guide, with a record in PROSPERO using DeCS and Boolean operators OR and AND to increase the specificity of the search. In the EBSCOST, Pubmed, Cochrane Library and Scopus databases, 184 studies were obtained. Patients ≥18 years of age with scheduled surgeries, communication skills, clinical trials or quasi experimental studies were included. The risk of bias 2 (RoB2) tool was used to assess the risk of bias in the studies. A random effects meta-analysis was performed to analyze pre- and post-operative anxiety and post-operative pain. RESULTS A total of 6 studies were included (4 clinical trials and 2 quasi experimental studies). All studies analyzed preoperative anxiety, which was significantly lower (OR = -1.53; 95% CI: - 4.01 to -0.95; I² = 40%). There was also a decrease in postoperative pain (OR = -0.74; 95% CI: - 0.94 to -0.54; I² = 35%) and postoperative anxiety (OR = -0.48; 95% CI: - 0.78 to -0.19; I² = 0%). CONCLUSIONS Motivational interviews by nurses effectively offered clear information and allowed patients to express doubts, reducing their fear of anesthesia, pain and the recovery process. Emotional control improved adaptation to the surgical environment, reducing postoperative pain. With respect to implications for clinical practice, it is necessary to use the same scales to measure anxiety to better compare the studies.

Background and Objectives: Anxiety can influence the intensity of postoperative pain, anesthesia and the need for analgesia. Likewise, proper anxiety management can reduce hospital stays. Therefore, it is important to review the actions of nursing professionals and estimate the effect size of nursing interventions to reduce anxiety in pre- and postsurgical processes. Therefore, the objective of this study was to analyze the effectiveness of preoperative motivational interviews by nursing to reduce pre- and postoperative anxiety and postoperative pain after surgery. Materials and Methods: A systematic review was carried out according to the PRISMA guidelines, with a record in PROSPERO using DeCS and Boolean operators OR and AND to increase the specificity of the search. In the EBSCOhost, Pubmed, Cochrane Library and Scopus databases, 104 studies were obtained. Patients ≥ 18 years of age with scheduled surgeries, communication skills, clinical trials or quasi-experimental studies were included. The risk of bias 2 (RoB2) tool was used to assess the risk of bias in the studies. A random effects meta-analysis was performed to analyze pre- and postoperative anxiety and postoperative pain. Results: A total of 6 studies were included (4 clinical trials and 2 quasi-experimental studies). All the studies analyzed preoperative anxiety, which was significantly lower (SMD = −1.53; 95% CI: −4.01 to −0.95; I² = 40%). Postoperative pain (SMD = −0.74; 95% CI: −0.94 to −0.54; I² = 35%) and postoperative anxiety (SMD = −0.48; 95% CI: −0.78 to −0.19; I² = 0%) also decreased. Conclusions: Motivational interviews by nurses may help provide clearer information and emotional support and allow patients to express doubts, reducing their fear of anesthesia, pain and the recovery process. Emotional control improved adaptation to the surgical environment, reducing postoperative pain. With respect to implications for clinical practice, it is necessary to use the same scales to measure anxiety to better compare the studies.

Background: Burns represent a public health problem because they generate both physical and psychological damage, especially in the child and adolescent population, and high costs, especially due to the management of scars. Advances in burn care have improved survival and quality of life for this population. New clinical trials have been conducted on the benefits of negative pressure wound therapy (NPWT), showing that it improves the healing of burns and the appearance of scars. Therefore, this study aims to analyze the efficacy of NPWT both alone and as an adjunct to conventional dressings in pediatric and adolescent patients compared with conventional treatments. Methodology: A systematic search was carried out between December 2023 and the last quarter of 2025 in databases such as PubMed, Scopus, CINAHL, and the Cochrane Library. This meta-analysis was performed following the PRISMA statement (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) and was registered in PROSPERO with registration number CRD42024597293. The risk of bias 2 (RoB2) tool was used to assess the risk of bias in the studies. Quantitative meta-analyses using random-model effects were performed only for variables with sufficient comparable data among studies. For other outcomes, where meta-analysis was not feasible due to lack of comparable data or control groups, results were synthesized qualitatively. Results: A total of seven articles (three clinical trials and four retrospective studies), in which a total of 323 subjects participated, were included. The main results demonstrate the efficacy of NPWT, as it decreases the re-epithelialization time, improves the appearance of scars (MD = −1.25 (95% CI between −1.80 and −0.70)), reduces the probability of skin grafts (OR = 0.17 (95% CI between 0.06 and 0.46)), and therefore, as there is less need for surgery and fewer dressing changes, reduces costs. Conclusions: NPWT offers significant clinical benefits in the treatment of burns in children and adolescents. Although a meta-analysis could not be performed due to the lack of a control group in some studies, studies with larger samples and multicenter designs will be necessary to better assess the relevant clinical outcomes. However, the results of this study show that NPWT is effective in treating burns in children and adolescents and that its use in clinical practice may represent a promising adjunctive therapy.

Background: Chronic lower limb wounds, such as diabetic and vascular ulcers, affect up to 2% of the global population, imposing high healthcare costs and a significant risk of amputation. Although nursing care and traditional treatments are fundamental, single-use portable Negative Pressure Wound Therapy PICO 7 system, has emerged as a cost-effective alternative. The objective of this study was to evaluate the effectiveness of PICO 7, compared to the usual treatment in chronic lower limb wounds or their dehiscence in amputations. Methodology: A randomized, controlled, open-label clinical trial was conducted at the Hospital Universitario de Toledo (2024–2026). The final analyzed sample consisted of 31 patients (Intervention Group, IG: 14; Control Group, CG: 17). Both groups followed the dynamic TIME strategy to standardize wound bed preparation. Primary variables included healing rate, healing time, wound area reduction, clinical safety (infections and adverse effects), pain levels, health-related quality of life, and physical activity. Statistical analysis was performed using SPSS v.28. Results: The IG showed a higher mean percentage reduction in wound size, although the between-group difference did not reach statistical significance. No infections were recorded in the IG. Regarding quality of life and physical activity, the CG showed a significant post-intervention decline, whereas the IG remained stable. A significant negative correlation was found between final wound size and hours of sleep, suggesting that wound reduction facilitates better rest. Conclusions: The PICO 7 system appears to be a safe and feasible alternative to conventional wound care. Favorable trends in wound area reduction should be interpreted cautiously given the lack of statistically significant between-group differences.
