Spinal cord stimulation (SCS) has emerged as a potential therapeutic tool for various chronic conditions, but its efficacy in post-operative wound healing for multiple sclerosis (MS) patients has not been comprehensively understood. This meta-analysis aimed to evaluate the impact of SCS on post-operative wound healing and scar formation in MS patients. A systematic literature review identified seven studies for inclusion. We focused on wound healing as measured by the redness, edema, ecchymosis, discharge, approximation (REEDA) scale 1 week post-operation and scar formation assessed by the Manchester Scar Scale (MSS) 3 months post-operation. The results demonstrated a significant improvement in wound healing in the SCS group, with a standard mean difference (SMD) of −5.82 (95% confidence interval [CI]: [−7.56, −4.09], p < 0.01) on the REEDA scale. For scar formation, the SCS group showed a notable reduction in MSS scores, with an SMD of −10.06 (95% CI: [−14.53, −5.58], p < 0.01). These findings underscore the potential of SCS as an adjunct therapy in enhancing surgical recovery in MS patients, pointing towards its broader applications in post-operative care.
This meta-analysis assesses the impact of Enhanced Recovery After Surgery (ERAS) protocols on surgical site wound infections (SSWIs) in urological procedures. Analysing data from 10 studies, our focus was on SSWI rates on the third and seventh postoperative days. The results reveal a significant reduction in SSWI rates for patients managed under ERAS protocols compared with traditional care. Notably, Figure 4 demonstrates a substantial decrease in SSWI on the third day (I 2 = 93%; random: standardized mean difference [SMD]: −6.25, 95% confidence interval [CI]: −7.42 to −5.05, p < 0.01), and Figure 5 mirrors this trend on the seventh day (I 2 = 95%; random: SMD: −4.72, 95% CI: −6.28 to −3.16, p < 0.01). These findings underscore the effectiveness of ERAS protocols in minimizing early postoperative wound infections, emphasizing their importance for broader implementation in urological surgeries.
Diabetic foot ulcers can have vital consequences, such as amputation for patients. The primary purpose of this study is to predict the amputation risk of diabetic foot patients using machine-learning classification algorithms. In this research, 407 patients treated with the diagnosis of diabetic foot between January 2009–September 2019 in Istanbul University Faculty of Medicine in the Department of Undersea and Hyperbaric Medicine were retrospectively evaluated. Principal Component Analysis (PCA) was used to identify the key features associated with the amputation risk in diabetic foot patients within the dataset. Thus, various prediction/classification models were created to predict the “overall” risk of diabetic foot patients. Predictive machine-learning models were created using various algorithms. Additionally to optimize the hyperparameters of the Random Forest Algorithm (RF), experimental use of Bayesian Optimization (BO) has been employed. The sub-dimension data set comprising categorical and numerical values was subjected to a feature selection procedure. Among all the algorithms tested under the defined experimental conditions, the BO-optimized “RF” based on the hybrid approach (PCA-RF-BO) and “Logistic Regression” algorithms demonstrated superior performance with 85% and 90% test accuracies, respectively. In conclusion, our findings would serve as an essential benchmark, offering valuable guidance in reducing such hazards.
In this article, we analysed the therapeutic efficacy of open radical prostatectomy (ORP) and minimally invasive surgery (MIS) after operation for the treatment of post-operation complications. In summary, because of the broad methodology of the available trials and the low number of trials, the data were limited. The investigators combined the results of six of the 211 original studies. We looked up 4 databases: PubMed, EMBASE, Web of Science and the Cochrane Library. A total of six publications were selected. The main result was the rate of post-operation wound complications. Secondary results were the time of operation and the duration of hospitalization. Our findings indicate that the minimal invasive operation can decrease the incidence of wound infections (OR, 0.61; 95% CI: 0.42,0.90, p = 0.01), bleeding (MD, −293.09; 95% CI: −431.48, −154.71, p < 0.0001), and length of stay in the hospital compared with open surgery (MD, −1.85; 95% CI: −3.52, −0.17, p = 0.03), but minimally invasive surgery increased patient operative time (MD, 51.45; 95% CI: 40.99, 61.92, p < 0.0001). Compared with the open operation, the microinvasive operation has the superiority in the treatment of the wound complications following the operation of radical prostatic carcinoma. But the operation time of the microinvasive operation is much longer. Furthermore, there is a certain amount of bias among the various studies, so it is important to be cautious in interpretation of the findings.
The meta-analysis aimed to assess and compare diabetic foot wound ulcer management by vacuum sealing drainage. Using dichotomous or contentious random- or fixed-effects models, the outcomes of this meta-analysis were examined, and the odds ratio (OR) and the mean difference (MD) with 95% confidence intervals (CIs) were computed. Twenty-three examinations from 2000 to 2023 were enrolled for the present meta-analysis, including 1928 individuals with diabetic foot ulcers. Vacuum sealing drainage had significantly lower wound healing (OR, 2.35; 95% CI, 1.79–3.08, p < 0.001), lower duration of therapy (MD, −6.19; 95% CI, −10.06 to −2.32, p = 0.002), higher wound size reduction (MD, 4.22; 95% CI, 0.87–7.56, p = 0.01) and lower complication (OR, 0.32; 95% CI, 0.13–0.80, p = 0.01) compared with standard therapy in patients with diabetic foot ulcers. The examined data revealed that vacuum sealing drainage had significantly lower wound healing, duration of therapy and complication rates, as well as higher wound size reduction, compared with standard therapy in patients with diabetic foot ulcers. Yet, attention should be paid to its values since most of the selected examinations had a low sample size.
Preserved allogeneic donor skin still represents one of the gold standard therapies in temporary wound coverage in severely burned patients or chronic wounds. Allogeneic skin grafts are currently commercially available as cryo- or glycerol-preserved allografts through skin tissue banks all over the world. Most of the skin tissue banks rely on human cadaveric skin donations. Due to the chronic shortage of human allogeneic transplants, such as skin, and increasing costs in the procurement of allografts from other skin tissue banks, Hannover Medical School has been building up its own skin tissue bank based on allogeneic skin grafts from living donors who underwent surgical treatment (i.e., body-contouring procedures, such as abdominioplasties). This article presents procedures and protocols for the procurement and processing of allogeneic skin grafts according to national legislation and European regulations and guidelines. Beside protocols, initial microbiological data regarding the sterility of the harvested grafts are presented. The results currently form the basis for further investigations as well as clinical applications. In summary, a microbiological testing and acceptance procedure is presented that ensures adequate patient safety and skin viability.
This study aims to (1) characterize healthcare professionals' (HCPs') experiences related to the prevention and management of pressure injuries (PIs) and (2) explore the educational needs of individuals with a past or current history of PIs and their caregivers from the perspective of HCPs. This is a qualitative descriptive study. HCPs (n = 18) were interviewed using a semi-structured interview guide. Interviews were audio-recorded, transcribed verbatim and coded using NVivo. Three overarching themes encompassing various dimensions were identified: (1) Facilitators related to PI prevention and management, (2) Challenges related to PI prevention and management and (3) Recommendations for improving patient and caregiver PI education. HCPs identified a greater number of challenges than facilitators related to PI care. This study emphasizes the importance of a patient-centred and interprofessional approach to patient education for PI prevention and management. Meaningful interventions focused on the patient may improve health literacy and empower patients and caregivers in PI care. Investing in preventive measures and raising awareness are crucial to reducing PI incidence. The findings have implications for HCPs and researchers seeking to enhance patient care and promote effective PI prevention strategies.
The purpose of this study was to compare the reconstructive outcomes of soft-tissue defects around foot and ankle with vaccum sealing drainage (VSD) or induction membrane (IM) of cement formation and attempt to provide an optimal strategy for elderly patients. A retrospective review of all continuous patients with foot and ankle reconstruction using different flaps from October of 2016 and October of 2020 was performed. Based on the different way, the patients were divided into two groups: VSD group (n = 26) and IM group (n = 27). Outcomes were assessed according to the size of the defect, frequency of debridement procedures, hospitalization time, duration of healing, the healing rate, major amputation rate, functional outcomes and complications. Immunohistochemistry (IHC) detection of vascular endothelial growth factor (VEGF) was also be completed. We found that there was no difference in demographic characteristics, size of the defect, debridement times and functional outcomes between the two groups (p > 0.05); however, a significant difference in the wound healing time, hospitalization time and complications were noted between them(p < 0.05). The fresh granulation tissue of both groups showed abundant positive expression of VEGF. Thus, the VSD and IM are both available for foot and ankle reconstruction in elderly patients. However, the IM group offers short hospitalization time, duration of healing and lower frequency of postoperative complications. Thus, we advocate the IM for reconstruction of defects of the foot and ankle region in the elderly patients.
Necrotizing fasciitis is a progressive and rare disease, with high potential to be life-threatening because of its potential for systemic toxicity. Characterized by fascial infection, it is often followed by systemic toxicity, such as septic shock and multi-organ failure. The aim of this study is to establish reliable data on the treatment of necrotizing fasciitis patients at the topmost referral hospital in West Java, Indonesia. We collected medical record data from January 2015 to December 2021 at Rumah Sakit Umum Pusat Dr. Hasan Sadikin (RSHS), Bandung, Indonesia. We recorded the infection region, bacterial isolates, empirical antibiotics, waiting time for the first surgery, surgical management, length of stay and we analysed the pattern of bacterial isolates, antibiotic use, waiting time for the first surgery, length of stay and mortality. A total of 90 patients' medical records were analysed. We found that the infection was most found in the genitalia and inguinal region (37%). Eighty-five percent of all samples containing gram-negative bacteria. The most used empirical antibiotics were from Cephalosporin class (31%), most of them combined with nitroimidazole (metronidazole) and with quinolones (levofloxacin, ciprofloxacin). Overall mortality rate was 13.3%. Highest mortality rate came from gram-negative bacteria group (14.2%—11 out of 77 patients), patients receiving Ceftriaxone–Metronidazole as empirical antibiotics (28.57%—4 out of 14 patients), patients with no surgery group (37%—3 out of 8 patients), with no mortality came from patients, which were performed debridement followed by fasciotomy/skin graft/flap and amputation. We conclude that the most found bacterial aetiology was Acinetobacter baumanii though it has no significant relation to mortality. We highly recommend early aggressive surgical intervention in reducing mortality rate due to necrotizing fasciitis for source control accompanied by deliberate defect closure and early administration of empirical antibiotics with more susceptibility for gram-negative bacteria, such as Meropenem.
WOUND-Q is a condition-specific patient-reported outcome measure developed for all types of chronic wounds, located anywhere on the body. To establish reliability and validity of a patient-reported outcome measure, multiple pieces of evidence are required. The purpose of this study was to examine the measurement properties of 9 of the 13 WOUND-Q scales and perform a test–retest reproducibility study in an international sample. In August 2022, we invited members of an international online community (Prolific.com) with any type of chronic wound to complete a survey containing the WOUND-Q scales, the Wound-QoL and EQ-5D. A test–retest survey was performed 7 days after the first survey. It was possible to examine the reliability and validity of eight of the nine WOUND-Q scales by Rasch Measurement Theory (RMT). To examine test–retest reproducibility intraclass correlation coefficients (ICCs), the standard error of the measurement and the smallest detectable change were calculated. In total, 421 patients from 22 different countries with 11 different types of chronic wounds took part in this study. Our analyses provided further evidence of the reliability and validity of the scales measuring wound characteristics (assessment, drainage, smell), health-related quality of life (life impact, psychological, sleep, social) and wound treatment (dressing).
A limited understanding of the pathology underlying chronic wounds has hindered the development of effective diagnostic markers and pharmaceutical interventions. This study aimed to elucidate the molecular composition of various common chronic ulcer types to facilitate drug discovery strategies. We conducted a comprehensive analysis of leg ulcers (LUs), encompassing venous and arterial ulcers, foot ulcers (FUs), pressure ulcers (PUs), and compared them with surgical wound healing complications (WHCs). To explore the pathophysiological mechanisms and identify similarities or differences within wounds, we dissected wounds into distinct subregions, including the wound bed, border, and peri-wound areas, and compared them against intact skin. By correlating histopathology, RNA sequencing (RNA-Seq), and immunohistochemistry (IHC), we identified unique genes, pathways, and cell type abundance patterns in each wound type and subregion. These correlations aim to aid clinicians in selecting targeted treatment options and informing the design of future preclinical and clinical studies in wound healing. Notably, specific genes, such as PITX1 and UPP1, exhibited exclusive upregulation in LUs and FUs, potentially offering significant benefits to specialists in limb preservation and clinical treatment decisions. In contrast, comparisons between different wound subregions, regardless of wound type, revealed distinct expression profiles. The pleiotropic chemokine-like ligand GPR15L (C10orf99) and transmembrane serine proteases TMPRSS11A/D were significantly upregulated in wound border subregions. Interestingly, WHCs exhibited a nearly identical transcriptome to PUs, indicating clinical relevance. Histological examination revealed blood vessel occlusions with impaired angiogenesis in chronic wounds, alongside elevated expression of genes and immunoreactive markers related to blood vessel and lymphatic epithelial cells in wound bed subregions. Additionally, inflammatory and epithelial markers indicated heightened inflammatory responses in wound bed and border subregions and reduced wound bed epithelialization. In summary, chronic wounds from diverse anatomical sites share common aspects of wound pathophysiology but also exhibit distinct molecular differences. These unique molecular characteristics present promising opportunities for drug discovery and treatment, particularly for patients suffering from chronic wounds. The identified diagnostic markers hold the potential to enhance preclinical and clinical trials in the field of wound healing.
This meta-analysis investigates the effect of dexmedetomidine on postoperative wound healing in neurosurgical patients. A thorough literature search resulted in the selection of seven studies from an initial pool of 1546 records. The analysis focused on wound healing outcomes, evaluated by the Redness, Oedema, Ecchymosis, Discharge, Approximation (REEDA) scale and the Manchester Scar Scale (MSS). Results indicated significant improvements in the dexmedetomidine group: the REEDA scale scores at day seven post-surgery showed a Standardized Mean Difference group (SMD = −16.18, 95% CI: [−22.30, −10.06], p < 0.01), and the MSS scores at 3 months post-operation demonstrated an (SMD = −8.95, 95% CI: [−14.27, −3.62], p < 0.01). These findings suggest that dexmedetomidine may enhance wound healing and reduce scar formation in neurosurgical patients. Bias assessment indicated a low risk of bias across the studies.
The Wound-QoL assesses the impact of chronic wounds on patients' health-related quality of life (HRQoL). A 17-item and a shortened 14-item version are available. The Wound-QoL-17 has been validated for multiple languages. For the Wound-QoL-14, psychometric properties beyond internal consistency were lacking. We aimed to validate both Wound-QoL versions for international samples representing a broad range of European countries, including countries for which validation data had yet been pending. Patients with chronic wounds of any aetiology or location were recruited in Austria, Lithuania, the Netherlands, Poland, Slovakia, Spain, Switzerland and Ukraine. Psychometric properties were determined for both Wound-QoL versions for the overall sample and, if feasible, country-wise. We included 305 patients (age 68.5 years; 52.8% males). Internal consistency was high in both Wound-QoL-17 (Cronbach's α: 0.820–0.933) and Wound-QoL-14 (0.779–0.925). Test–retest reliability was moderate to good (intraclass correlation coefficient: 0.618–0.808). For Wound-QoL-17 and Wound-QoL-14, convergent validity analyses showed highest correlations with global HRQoL rating (r = 0.765; r = 0.751) and DLQI total score (r = 0.684; r = 0.681). Regarding clinical data, correlations were largest with odour (r = −0.371; r = −0.388) and wound size (r = 0.381; r = 0.383). Country-wise results were similar. Both Wound-QoL versions are valid to assess HRQoL of patients with chronic wounds. Due to its psychometric properties and brevity, the Wound-QoL-14 might be preferrable in clinical practice where time is rare. The availability of various language versions allows for the use of this questionnaire in international studies and in clinical practice when foreign language patients are being treated.
Surgical site infections (SSIs) post-thoracoscopic radical resection in lung cancer patients pose significant clinical challenges. This study aims to comprehensively identify the independent risk factors that influence the occurrence of SSIs following thoracoscopic radical resection for lung cancer. The study employed a retrospective analysis of 130 patients who underwent thoracoscopic radical resection for lung cancer. Inclusion and exclusion criteria were clearly defined, and ethical approvals were obtained. Patients were monitored for SSIs via clinical and biochemical markers, with data comprehensively gathered from electronic health records. Statistical analysis was rigorously conducted using SPSS v27.0, with methodologies including t-tests, Chi-square tests and logistic regression. The study aimed to identify independent risk factors for SSIs and incorporated a multidimensional assessment approach to provide robust, clinically relevant findings. Univariate analysis revealed surgical duration ≥3 h, non-usage of antibiotics, presence of diabetes and elevated levels of C-reactive protein (CRP) and procalcitonin (PCT) as significant correlates for SSIs. Multivariate analysis substantiated these factors as independent risk variables: surgery duration (odds ratio [OR] = 9.698, p < 0.05), presence of diabetes (OR = 6.89, p < 0.05), elevated CRP (OR = 7.306, p < 0.05) and elevated PCT (OR = 6.838, p < 0.05). Conversely, antibiotic administration served as a protective factor (OR = 0.572, p < 0.05). Surgical duration of 3 h or more, diabetes and elevated levels of CRP and PCT significantly heighten the risk for SSIs after thoracoscopic radical resection in lung cancer patients. Perioperative antibiotic administration acts as a protective factor. Clinicians should implement tailored preventative strategies to mitigate these identified risks.
Diabetic foot ulcer often leads to amputation, and both nutritional status and immune function have been associated with this process. We aimed to investigate the risk factors of diabetic ulcer-related amputation including the Controlling Nutritional Status score and neutrophil-to-lymphocyte ratio biomarker. We evaluated data from hospital in patients with diabetic foot ulcer, performing univariate and multivariate analyses to screen for high-risk factors and Kaplan–Meier analysis to correlate high-risk factors with amputation-free survival. Overall, 389 patients underwent 247 amputations over the follow-up period. After correction to relevant variables, we identified five independent risk factors for diabetic ulcer-related amputation: ulcer severity, ulcer site, peripheral arterial disease, neutrophil-to-lymphocyte ratio and nutritional status. Amputation-free survival was lower for the moderate-to-severe versus mild cases, for the plantar forefoot versus hindfoot location, for the concomitant peripheral artery disease versus without and in the high versus low neutrophil-to-lymphocyte ratio (all p < 0.01). The results showed that ulcer severity (p < 0.01), ulcer site (p < 0.01), peripheral artery disease (p < 0.01), neutrophil-to-lymphocyte ratio (p < 0.01) and Controlling Nutritional Status score (p < 0.05) were independent risk factors for amputation in diabetic foot ulcer patients and have predictive values for diabetic foot ulcer progression to amputation.
A novel autologous heterogeneous skin construct (AHSC) was previously shown to be effective versus standard of care (SOC) treatment in facilitating complete wound healing of Wagner 1 diabetic foot ulcers in an interim analysis of 50 patients previously published. We now report the final analysis of 100 patients (50 per group), which further supports the interim analysis findings. Forty-five subjects in the AHSC treatment group received only one application of the autologous heterogeneous skin construct, and five received two applications. For the primary endpoint at 12 weeks, there were significantly more diabetic wounds closed in the AHSC treatment group (35/50, 70%) than in the SOC control group (17/50, 34%) (p = 0.00032). A significant difference in percentage area reduction between groups was also demonstrated over 8 weeks (p = 0.009). Forty-nine subjects experienced 148 adverse events: 66 occurred in 21 subjects (42%) in the AHSC treatment group versus 82 in 28 SOC control group subjects (56.0%). Eight subjects were withdrawn due to serious adverse events. Autologous heterogeneous skin construct was shown to be an effective adjunctive therapy for healing Wagner 1 diabetic foot ulcers.
With the outbreak and pandemic of coronavirus disease-2019 (COVID-19), a huge number of people died of it. Apart from lung injuries, multiple organs have been confirmed to be impaired. In COVID-19 time, primary wound healing processes always prolong, however, its possible underlying mechanisms are still unclear. Therefore, to overcome this clinical problem, clarifying its underlying mechanisms clearly is necessary and urgently needed. In this review, we summarized that COVID-19 can prolong primary wound healing by inducing excessive inflammation and oxidative stress, disturbing immune system and haematological system, as well as influencing the functions and viability of epidermal stem cells (ESCs). Otherwise, we summarized that the strict control measures of blocking up COVID-19 pandemic can also have side effects on primary wound healing process.
Chronic wounds can severely limit patient's social life. This cross-sectional study investigated quantitatively social support of patients with chronic wounds, its association with health-related quality of life as well as qualitatively changes in social participation of these patients. Overall, 263 patients from seven countries participated. The most frequent wound class was leg ulcer (49.2%). Results revealed generally high levels of social support (mean global score: 5.5) as measured with the Multidimensional Scale of Perceived Social Support. However, individuals differed considerably (range 1.0–7.0). All dimensions of social support differed by patients' family and living situations (p < 0.001 to p = 0.040) and were positively correlated with generic health-related quality of life (r = 0.136–0.172). Having children, living with others and being in a relationship were significant predictors of having higher global social support. Patients reported great support from family members. Many participants reported no changes in relationships with friends. Wound care managers took an important role and provided additional emotional support. Patients reported a range of discontinued activities. Despite the high overall level of social support, inter-individual differences should be acknowledged. The importance of family carers should be acknowledged to be able to reduce caregiver burden and to ensure high-qualitative wound care.
To prevent anastomotic leakage and other postoperative complications after laparoscopic rectal cancer surgery, a protective ileostomy is often used. However, the necessity of performing ileostomy after laparoscopic rectal cancer remains controversial. The aim of this meta-analysis was to assess the benefit of ileostomy on wound infection after laparoscopic rectal cancer. The Cochrane Library, EMBASE, Web of Science, and PubMed were used to retrieve all related documents up to September 2023. Completion of the trial literature was submitted once the eligibility and exclusion criteria were met and the literature quality assessment was evaluated. This study compared the post-operative post-operative complications of an ileostomy with that of non-ileostomy in a laparoscope. We used Reman 5.3 to analyse meta-data. Controlled studies were evaluated with ROBINS-I. The meta-analyses included 525 studies, and 5 publications were chosen to statistically analyse the data according to the classification criteria. There was no statistically significant difference in the rate of postoperative wound infections among ostomate and nonostomate (odds ratio [OR], 1.79; 95% confidence interval [CI], 0.66, 4.84; p = 0.25). In 5 trials, the incidence of anastomotic leak was increased after surgery in nonostomate patients (OR, 0.26; 95% CI, 0.12, 0.57; p = 0.0009). Two studies reported no significant difference in the length of operation time when nonstomal compared to stomal operations in patients with rectal cancer (mean difference, 0.87; 95% CI, −2.99, 4.74; p = 0.66). No significant difference was found in the rate of wound infection and operation time after operation among the two groups, but the incidence of anastomosis leak increased after operation. Protective ileostomy after laparoscopic rectal cancer was effective in reducing the risk of anastomotic leakage in patients, and we found no additional risk of infection. We cautiously conclude that protective ileostomy is active and necessary for patients with a high risk of anastomotic leakage after surgery, which needs to be further confirmed by high-quality studies with larger samples.
