Diabetic foot wounds (DFW) are notoriously difficult to treat owing to poor vascularity, delayed healing and higher rates of infection. Human-derived acellular dermal matrices (ADM) have been used in DFW treatment, utilizing a matrix scaffold for new tissue generation. We investigate the efficacy of a micronized injectable human-derived ADM in the treatment of DFW. We retrospectively recruited 13 patients with diabetic foot wounds. Wounds were adequately debrided, and a micronized injectable ADM was applied. Wound sizes were recorded prior to treatment, at 2 and 4 weeks post-treatment. The mean defect of wounds treated was 19.21 cm3. Our results showed a statistically significant reduction in wound size of 45% and 59% at 2 and 4 weeks post-treatment, respectively (p < 0.01). ADM was also effective in infected DFW as 84% of our wounds had positive tissue cultures at the time of application. Micronized injectable ADM has proven to be an effective treatment for DFW. Advantages include a ready-to-use injectable, single-stage treatment, minimal pain, mouldable matrix to fit any wound shape, allows for outpatient treatment and simple wound dressings.
To investigate the knowledge, attitudes and practices of intensive care unit (ICU) nurses regarding acute skin failure (ASF) and analyse the influencing factors thereof.
From 22 December 2023 to 24 January 2024, a cross-sectional study was conducted amongst ICU nurses from 21 hospitals in eight provinces in China. The ASF knowledge, attitude and practice scores were determined using questionnaires, and multiple linear regression was used for further analysis.
Overall, 304 ICU nurses completed the survey. The knowledge, attitude and practice scores were 24.89 ± 10.93, 40.67 ± 5.93 and 43.47 ± 9.19, with scoring rates of 45.25%, 81.34% and 72.45%, respectively. Multiple linear regression analysis showed that being a wound ostomy specialist nurse was positively correlated with the knowledge dimension score (p < 0.05). Nurses' professional titles significantly affected attitude scores (p < 0.05); the higher the professional title, the more positive the attitude towards ASF.
The attitudes and practices of ICU nurses in China towards ASF were found to be positive; however, their knowledge levels need improvement. Nursing managers should conduct targeted training, especially for entry-level nurses.
Efficient wound assessment is essential for healthcare teams to facilitate prompt diagnosis, optimize treatment plans, reduce workload, and enhance patients' quality of life. In recent years, non-invasive techniques for aiding wound assessment, such as digital photography, 3D modelling, optical imaging, fluorescence and thermography, as well as artificial intelligence, have been gradually developed. This paper aims to review the various methods of measurement and diagnosis based on non-invasive wound imaging, and to summarize their application in wound monitoring and assessment. The goal is to provide a foundation and reference for future research on wound assessment.
This study was to translate the Pieper–Zulkowski pressure ulcer knowledge test (PZ-PUKT) into Traditional Chinese and evaluate its psychometric properties as well as identify the predictors of knowledge on pressure injury. The PZ-PUKT was translated into Traditional Chinese (TC-PZ-PUKT), and its content validity was evaluated. A total of 296 nurses participated in this study and completed the 72-item TC-PZ-PUKT online. The reliability of the TC-PZ-PUKT was analysed by evaluating its internal consistency and test–retest reliability. Hierarchical regression was used to determine factors associated with TC-PZ-PUKT scores. Content validity was achieved with a score of 0.986. Internal consistency was observed to be reliable, with a Cronbach's alpha of 0.858. The mean knowledge score on the TC-PZ-PUKT was 72.5%, with a 1-week test–retest reliability of r = 0.849. Education level, certification as a wound specialist and self-learning through reading articles, books or guidelines on pressure injury were significantly associated with TC-PZ-PUKT scores. The TC-PZ-PUKT is a valid and reliable tool. Education level, certification as a wound specialist and self-learning regarding pressure injury are related to knowledge of pressure injury.
This study analysed the incidence of lower extremity amputation and its associated risk factors in patients with diabetic foot ulcers. This study systematically searched both Chinese and English databases, including CNKI, Wanfang, VIP, PubMed, EMBASE and Web of Science, to identify cohort studies related to lower extremity amputation and associated risk factors in patients with diabetic foot ulcers up to October 2023. The patients were stratified based on whether they underwent lower extremity amputation, and relevant data, including basic information, patient characteristics, complications, comorbidities and pertinent laboratory test data, were extracted from the included studies. The literature quality assessment in this study utilized the Newcastle-Ottawa Scale to screen for high-quality literature, resulting in the inclusion of 16 cohort studies, all of which were of at least moderate quality. Meta-analysis of outcome indicators was conducted using the Stata 14.0 software. The results indicate that the overall amputation rate of lower extremities in patients with diabetic foot ulcers is 31% (0.25, 0.38). Among the 16 variables evaluated, gender (male), smoking history, body mass index (BMI), hypertension, cardiovascular disease, kidney disease, white blood cell count, haemoglobin and albumin levels were found to be correlated with the occurrence of lower extremity amputation in patients with diabetic foot ulcers. However, no significant correlation was observed between age, diabetes type, duration of diabetes, stroke, glycosylated haemoglobin, creatinine and total cholesterol levels and lower extremity amputation in patients with diabetic foot ulcers. This meta-analysis indicates that the overall amputation rate in patients with diabetic foot ulcers is 31%. Factors such as gender (male), smoking history, high BMI, hypertension, cardiovascular disease, kidney disease, white blood cell count, haemoglobin and albumin levels are identified as significant risk factors for lower extremity amputation in diabetic foot ulcer patients. These findings suggest that attention should be focused on these risk factors in patients with diabetic foot ulcers to reduce the risk of lower extremity amputation. Therefore, preventive and intervention measures targeting these risk factors are of significant importance in clinical practice.

This umbrella review aim to explore the effect of topical antibiotics in infection prevention after primary joint arthroplasty, and provide a specific theoretical basis for clinical treatment. The review process was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched PubMed, EMBASE, Medline, and the Cochrane Library on infection prevention by topical antibiotics from inception to 10 April 2023. The two researchers individually and strictly screened the literature according to the inclusion and exclusion criteria, performed the literature quality evaluation and data extraction, and used Stata 17 for data analysis. This study included six studies with one systematic review and five meta-analyses. The pooled analysis showed that topical antibiotic administration effectively reduced the incidence of overall infection and periprosthetic joint infection. However, it does not reduce the risk of superficial infection. Besides, the topic of antibiotics significantly increases the incidence of other sterile complications of the incision. According to the current evidence, topical application of antibiotics can reduce the incidence of overall infection and periprosthetic joint infection after primary joint arthroplasty. Although it increases the incidence of complications such as delayed healing of incisions, the pros and cons should be weighed in clinical decision making. However, they should not be discarded due to side effects.
The purpose of the meta-analysis was to evaluate and compare the photodynamic therapy's effectiveness in treating infected skin wounds. The results of this meta-analysis were analysed, and the odds ratio (OR) and mean difference (MD) with 95% confidence intervals (CIs) were calculated using dichotomous or contentious random- or fixed-effect models. For the current meta-analysis, 6 examinations spanning from 2013 to 2021 were included, encompassing 154 patients with infected skin wounds were the used studies' starting point. Photodynamic therapy had a significantly lower wound ulcer size (MD, −4.42; 95% CI, −7.56–−1.28, p = 0.006), better tissue repair (MD, −8.62; 95% CI, −16.76–−0.48, p = 0.04) and lower microbial cell viability (OR, 0.13; 95% CI, 0.04–0.42, p < 0.001) compared with red light exposure in subjects with infected skin wounds. The examined data revealed that photodynamic therapy had a significantly lower wound ulcer size, better tissue repair and lower microbial cell viability compared with red light exposure in subjects with infected skin wounds. However, given that all examinations had a small sample size, consideration should be given to their values.
To evaluate the risk factors connected with diabetic foot care and investigate the impact of health education on promoting proper diabetic foot care practices. An explanatory and mixed-method study was performed. We administered a structured pretest questionnaire to patients diagnosed with Type 2 diabetes who frequented our health examination center and community health clinics. The survey encompassed patient demographics, basic knowledge concerning diabetic foot care, and self-care practices pertaining to diabetic foot care. Concurrent assessments and scoring were carried out. Following the survey, patients underwent health education sessions focusing on foot self-care behaviours. Their progress was reevaluated after 2 weeks to gauge its effectiveness. We identified educational attainment, diabetes duration, regular follow-up, and blood sugar control as critical factors influencing knowledge about foot care and self-care practices related to it. Pearson correlation analysis demonstrated a positive relationship between scores for diabetic foot care knowledge and scores for self-care behaviours (r = 0.32, p < 0.001). Health education led to a significant improvement in the self-care behaviours of diabetic patients. A variety of factors affect the occurrence of diabetic foot complications and the self-care behaviours associated with diabetic foot care. Health education proves to be an effective means of enhancing diabetic foot care behaviours.
To evaluate the efficacy of cognitive behavioural therapy (CBT) as a psychological intervention for elderly patients with extensive burns, focusing on its impact on emotional well-being, self-efficacy and quality of life. A prospective, randomized study involving 200 elderly burn patients was conducted from November 2021 to January 2023. The patients were randomly assigned to receive either standard care (control group) or burn care based on cognitive behavioural therapy (CBT-B) (study group), with 100 patients in each group. Outcome measures included the Visual Analog Scale (VAS) for pain assessment, 36-item Short Form Survey (SF-36) for quality of life, General Self-Efficacy Scale (GSES) and Rosenberg Self-Esteem Scale (RSES). The study revealed that CBT-based intervention significantly reduced anxiety and depression scores compared with standard care (p < 0.05). Additionally, patients in the CBT group exhibited improved self-efficacy, self-esteem and quality of life (p < 0.05). CBT proves to be a valuable intervention for elderly burn patients, effectively addressing emotional distress and enhancing their psychological well-being. By modifying negative cognitive patterns, providing coping mechanisms and fostering problem-solving skills, CBT-based care contributes to a more positive recovery experience and improved quality of life.
We conducted this study to investigate the effect of evidence-based care on surgical site wound infection after caesarean section. A computerised search of PubMed, Embase, Google Scholar, Cochrane Library, China National Knowledge Infrastructure and Wanfang databases for randomised controlled trials (RCTs) on the use of evidence-based care in caesarean section delivery was applied from the database inception to November 2023. Two researchers independently screened the literature, extracted data and performed quality assessment based on inclusion and exclusion criteria. Stata 17.0 software was applied for data analysis. Twenty-one RCTs involving 3269 caesarean sections were finally included. The analysis revealed the implementation of evidence-based nursing interventions was effective in reducing the incidence of post-caesarean section wound infections (OR = 0.29, 95% CI: 0.21–0.39, p < 0.001) and complications (OR = 0.29, 95% CI: 0.23–0.38, p < 0.001) compared with conventional care. This study shows that the application of evidence-based nursing in postoperative caesarean section care can effectively reduce the incidence of postoperative wound infection and complications and improve the quality of life, which is worthy of clinical nursing application and promotion.
This meta-analysis systematically evaluates the impact of rapid rehabilitation nursing interventions on wound infections and postoperative complications in patients undergoing thoracoscopic lung cancer surgery. A comprehensive literature search was conducted, from database inception to November 2023, using databases including PubMed, Embase, Google Scholar, Cochrane Library, China National Knowledge Infrastructure, and Wanfang databases to identify randomized controlled trials (RCTs) that focused on the application of rapid rehabilitation nursing in the perioperative period of thoracoscopic lung cancer surgery. Two researchers independently screened the literature, extracted data, and assessed the quality based on inclusion and exclusion criteria. Data analysis was performed using Stata 17.0 software. A total of 22 RCTs involving 2319 patients were included in the analysis. The results indicated that the application of rapid rehabilitation nursing in thoracoscopic lung cancer surgery significantly reduced the incidence of wound infections (OR = 0.32, 95% CI: 0.20–0.54, p < 0.001) and postoperative complications (OR = 0.24, 95% CI: 0.18–0.31, p < 0.001). This study demonstrates that implementing rapid rehabilitation nursing interventions during the perioperative period for patients undergoing thoracoscopic lung cancer surgery can significantly decrease the occurrence of wound infections and complications, thereby facilitating rapid patient recovery.
This meta-analysis systematically evaluates the impact of the enhanced recovery after surgery (ERAS) concept on surgical site wound infections and postoperative complications in gastric cancer patients. A comprehensive computerized search was conducted in PubMed, Embase, Google Scholar, Cochrane Library, China National Knowledge Infrastructure and Wanfang databases for randomized controlled trials (RCTs), from database inception to November 2023, exploring the application of the ERAS concept in the perioperative period of gastric cancer surgery. Two researchers independently screened the literature, extracted data, and conducted quality assessments based on inclusion and exclusion criteria. Data analysis was performed using Stata 17.0 software. A total of 24 RCTs involving 2050 gastric cancer patients were included. The analysis revealed a significantly lower incidence of wound infections (OR = 0.23, 95% CI: 0.14–0.40, p < 0.001) and postoperative complications (OR = 0.20, 95% CI: 0.15–0.27, p < 0.001) in the ERAS group compared to the standard care group. This study demonstrates that the application of the ERAS concept during the perioperative period in gastric cancer surgery can effectively reduce the occurrence of wound infections and complications, thereby facilitating postoperative recovery.
In this study, we explored the use of thermal imaging technology combined with computer vision techniques for assessing surgical incision healing. We processed 1189 thermal images, annotated by experts to define incision boundaries and healing statuses. Using these images, we developed a machine learning model based on YOLOV8, which automates the recognition of incision areas, lesion segmentation and healing classification. The dataset was divided into training, testing and validation sets in a 7:2:1 ratio. Our results show high accuracy rates in incision location recognition, lesion segmentation and healing classification, indicating the model's effectiveness as a precise and automated diagnostic tool for surgical incision healing assessment. Conclusively, our thermal image-based machine learning model demonstrates excellent performance in wound assessment, paving the way for its clinical application in intelligent and standardized wound management.
A systematic review and meta-analysis were conducted to evaluate the efficacy and safety of ablative laser combined with pulsed dye laser to treat pathological scars.
A systematic literature review was conducted to identify all blind, randomized, controlled trials of ablative laser and pulsed dye laser for treating pathological scars. The databases PubMed, Embase, and Cochrane were used. All research on ablative laser combined with PDL in treating pathological scars with ablative laser or no treatment as controls were included in the meta-analysis. The retrieved studies' reference lists were thoroughly examined.
POSAS and VSS were used as evaluation criteria in seven studies involving 189 patients. Effect of combined laser group therapy (−1.259 95% confidence interval, −1.515 to −1.003; p < 0.0001). The difference between the combined treatment and control groups was (−1.375; 95% CI, −1.727 to −1.023; p < 0.0001) and (−1.150; 95% CI, −1.523 to −0.777; p < 0.0001).
Ablative laser combined with PDL is more effective and safer than ablative laser or PDL alone in the treatment of pathological scars.
The meta-analysis aims to evaluate and compare the sternal wound infections following internal mammary artery grafts for a coronary bypass. Examinations comparing bilateral internal mammary artery to single internal mammary artery for coronary artery bypass grafting were among the meta-analyses from various languages that met the inclusion criteria. Using dichotomous random- or fixed-effect models, the results of these investigations were examined, and the Odd Ratio (OR) with 95% confidence intervals (CIs) was computed. A total of 31 examinations from 2001 to 2023 were recruited for the current analysis including 181 503 personals with coronary artery bypass grafting. Bilateral internal mammary artery had significantly higher sternal wound infection (OR, 1.51; 95% CI, 1.37–1.68, p < 0.001), superficial sternal wound infection (OR, 1.72; 95% CI, 1.16–2.56, p = 0.007), deep sternal wound infection (OR, 1.62; 95% CI, 1.41–1.86, p < 0.001), sternal wound infection in diabetics (OR, 1.48; 95% CI, 1.16–1.90, p = 0.002), sternal wound infection in elderly (OR, 1.38; 95% CI, 1.22–1.57, p < 0.001), sternal wound infection in pedicled preparation (OR, 1.70; 95% CI, 1.30–2.23, p < 0.001) and sternal wound infection in skeletonized preparation (OR, 1.40; 95% CI, 1.09–1.81, p = 0.009) compared to single internal mammary artery in personals with coronary artery bypass grafting. Bilateral internal mammary artery grafting is linked to a higher risk of impaired wound healing, particularly in diabetic individuals, elderly, pedicled preparation, and skeletonized preparation. Nevertheless, caution should be exercised while interacting with its values since examinations were performed by different surgeons with different skills on different types of personals.
This study aims to investigate whether the current wound classifications were valid for the treatment prognosis of subjects treated for limb-threatening diabetic foot ulcers (LTDFU). A total of 1548 patients with LTDFU and infection were studied, with wounds recorded using the Wagner, Texas, PEDIS and WIfI classifications while major lower extremity amputations (LEAs) or in-hospital mortality incidences were defined as poor outcomes. Among them, 153 (9.9%) patients received major LEAs and 38 (2.5%) patients died. After adjustments, the Wagner classification and Texas stage as well as clinical factors such as comorbidity with major adverse cardiac events (MACE), being under dialysis and having serum levels of C-reactive protein (CRP) and albumin were independent factors for prognosis. For patients without dialysis, Wagner and Texas stage stood out independently for prognosis. For patients on dialysis, only levels of CRP (odds ratio [OR] = 2.2 in Wagner, OR = 2.0 in WIfI, OR = 2.2 in Texas, OR = 2.3 in PEDIS) and albumin (OR = 0.4 in four classifications) were valid predictors. The Wagner system and Texas stage were valid for predicting prognosis in treatment for LTDFUs, suggesting a role of vascular perfusion. MACE history, levels of CRP and albumin level should assist in prediction; more significantly, only levels of CRP and albumin appeared valid for those subjects undergoing dialysis.
To evaluate the efficacy of one-step acellular dermis combined with autologous split thickness skin grafting in the treatment of burn or trauma wounds by a multicenter controlled study. In patients with extensive burns, it is even difficult to repair the wounds due to the shortage of autologous skin. The traditional skin grafting method has the disadvantages of large damage to the donor site, insufficient skin source and unsatisfactory appearance, wear resistance and elasticity of the wound tissue after skin grafting. One-step acellular dermis combined with autologous ultra-thin split thickness skin graft can achieve better healing effect in the treatment of burn and trauma wounds. A total of 1208 patients who underwent single-layer skin grafting and one-step composite skin grafting in the First Affiliated Hospital of Wannan Medical College, Wuhan Third People's Hospital and Lu ‘an People's Hospital from 2019 to 2022 were retrospectively analysed. The total hospitalization cost, total operation cost, hospitalization days after surgery, wound healing rate after 1 week of skin grafting and scar follow-up at 6 months after discharge were compared and studied. The total cost of hospitalization and operation in the composite skin grafting group was significantly higher than those in the single-layer autologous skin grafting group. The wound healing rate after 1 week of skin grafting and the VSS score of scar in the follow-up of 6 months after discharge were better than those in the single-layer skin grafting group. One-step acellular dermis combined with autologous ultra-thin split thickness skin graft has high wound healing rate, less scar, smooth appearance and good elasticity in repairing burn and trauma wounds, which can provide an ideal repair method for wounds.
The utilization of 27-G TSV, or 27-Gauge Transconjunctival Sutureless Vitrectomy, poses distinct difficulties in the context of paediatric patients, particularly those younger than 14 years old, on account of the dearth of exhaustive documentation concerning the efficacy and results of these operations. Therefore, this retrospective study was to evaluate the safety and efficacy of 27-G TSV in paediatric patients, with emphasis on management of intraoperative and postoperative complications and postoperative wound healing. A total of 54 eyes of 52 paediatric patients who underwent 27-G TSV at Sichuan Provincial People's Hospital were included in the study. The average duration of follow-up was 9.32 ± 3.35 months. The complication with the highest incidence rate was Rhegmatogenous Retinal Detachment (RRD), which was detected in 27.8% cases. Familial Exudative Vitreoretinopathy (FEVR) and Persistent Fetal Vasculature (PFV) each accounted for 16.7% of the cases. Retinopathy of Prematurity (ROP) and Vitreous Haemorrhage (VH) constituted 11.1% and 14.8%, respectively, of the reported cases. Lens injury (1.9%), cannula slippage (7.4%) and wound leakage (5.6%) were intraoperative complications. Iatrogenic retinal detachment occurred at 3.7%. Hypotony (10.8% of patients), vitreous haemorrhage (9.3%), cataract formation (9.3%), ocular hypertension (8.1%) and retinal detachment (5.6%) were postoperative complications. Effective management strategies were executed, such as performing in situ trocar puncture to address cannula slippage and promptly suturing to address wound leakage. 27-G TSV exhibited promise as the therapeutic alternative for range of vitreoretinal disorders in paediatric patients, accompanied by complications that were controllable during and after the procedure. Strict preoperative planning and precise surgical technique are indispensable in order to maximize patient outcomes and guarantee effective wound healing and recovery within this particular demographic.
Wound healing is a complicated and multistage biological process for the repair of damaged/injured tissues, which requires intelligent designs to provide comprehensive and convenient treatment. Peptide-based wound dressings have received extensive attention for further development and application due to their excellent biocompatibility and multifunctionality. However, the current lack of intuitive analysis of the development trend and research hotspots of peptides applied in wound healing, as well as detailed elaboration of possible research hotspots, restricted obtaining a comprehensive understanding and development in this field. The present study analysed publications from the Web of Science (WOS) Core Collection database and visualized the hotspots and current trends of peptide research in wound healing. Data between January 1st, 2003, and December 31st, 2022, were collected and subjected to a bibliometric analysis. The countries, institutions, co-authorship, co-citation reference, and co-occurrence of keywords in this subject were examined using VOSviewer and CiteSpace. We provided an intuitive, timely, and logical overview of the development prospects and challenges of peptide application in wound healing and some solutions to the major obstacles, which will help researchers gain insights into the investigation of this promising field.
This study aimed to explore the association between metabolic-associated fatty liver disease (MAFLD) and ulcer recurrence risk in patients with diabetic foot ulcers (DFUs) through an ambispective longitudinal cohort. From December 2013 to December 2022, a total of 482 inpatients with DFUs (PEDIS grade 3 and above with a severe infection) were eligible for inclusion in this study. This was an ambispective longitudinal cohort study. All participants were followed up every 6 months for 9 years with a median of 36 months. According to whether having MAFLD or not, all subjects were placed into two groups: non-MAFLD (n = 351) and MAFLD (n = 131). The association between MAFLD and ulcer recurrence in patients with DFUs was then evaluated through multivariate Cox regression analysis, stratified analyses and Kaplan–Meier survival analysis. Throughout the follow-up period, out of 482 subjects with DFUs, 68 had ulcer recurrence (14.1%). Three Cox regression models were established for data analyses. In the model I (unadjusted), MAFLD was significantly associated with the ulcer recurrence rate in patients with DFUs (HR = 1.79; 95% CI = 1.097–2.92; p = 0.02). Model II (adjusted model I with gender and age) (HR = 1.781; 95% CI = 1.09–2.912; p = 0.021) and model III (adjusted model II with CVD, duration of diabetes and Cr.) (HR = 1.743; 95% CI = 1.065–2.855; p = 0.027) also showed that MAFLD was significantly related to the ulcer recurrence risk in patients with DFUs, respectively. Stratified analysis indicated that subjects aged ≥60 had a greater risk of ulcer recurrence in MAFLD than in non-MAFLD (HR = 2.31; 95% CI = 1.268–4.206; p = 0.006). Kaplan–Meier survival curve analysis showed that ulcer recurrence rate had a significant association with MAFLD (log-rank, p = 0.018). This study indicated a close association between ulcer recurrence risk and MAFLD in patients with DFUs, especially in the elderly (aged ≥60). Therefore, special attention should be paid to the elderly with both DFUs and MAFLD because they have a higher ulcer recurrence rate than other general populations in routine clinical practice.
