This meta-analysis was conducted to evaluate the effect of microinvasive and open operations on postoperative wound complications in low rectal carcinoma patients. Research on limited English has been conducted systematically in PubMed, Embase, Cochrane Library and Web of Science. The date up to the search was in August 2023. Following review of the classification and exclusion criteria for this research and the evaluation of its quality in the literature, there were a total of 266 related papers, which were reviewed for inclusion in the period from 2004 to 2017. A total of 1774 cases of low rectal cancer were enrolled. Of these 913 cases, the laparoscopic operation was performed on 913 cases, while 861 cases were operated on low rectal carcinoma. The overall sample was between 10 and 482. Five trials described the efficacy of laparoscopy have lower risk than open on postoperative wound infection in patients with low rectal cancer (OR, 0.72;95 % CI, 0.48,1.09 p = 0.12). Three studies results showed that the anastomotic leak was not significantly different between open and laparoscopy (OR, 0.86; 95% CI, 0.58,1.26 p = 0.44). Six surgical trials in low rectal cancer patients reported haemorrhage, and five cases of surgical time were reported, with laparoscopy having fewer bleeding compared with open surgery (MD, −188.89; 95% CI, −341.27, −36.51 p = 0.02). Compared with laparoscopy, the operation time was shorter for the open operation (MD, 33.06; 95% CI, 30.56, 35.57 p < 0.0001). Overall, there is no significant difference between laparoscopy and open surgery in terms of incidence of infection and anastomosis leak. However, the rate of haemorrhage in laparoscopy is lower，and operation time in open surgery is lower.
A meta-analysis was conducted to investigate the effects of platelet-rich plasma (PRP) in the treatment of burn wounds and to provide a scientific basis for clinical drug therapy. We searched PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure and Wanfang databases to identify randomised controlled trials (RCTs) on PRP in treating burn wounds, with the control group being treated with conventional treatments and the intervention group being treated with PRP alone or combined with PRP on the basis of the control group. The search duration was each database's inception to September 2023. The literature was screened, data were extracted and quality was assessed by two independent researchers. Data analysis was performed using the Review Manager 5.4 software. Eighteen RCTs comprising 1463 patients were included in the analysis. The meta-analysis revealed that the application of PRP significantly improved the wound healing rate (standardised mean difference [SMD]: 1.11, 95% confidence interval [CI]: 0.54–1.67, p < 0.001), shortened wound healing time (SMD: −1.69, 95% CIs: −2.21 to −1.17, p < 0.001) and reduced the incidence of adverse events (7.03% vs. 18.93%, odds ratio [OR]: 0.32, 95% CI: 0.20–0.53, p < 0.001), and also significantly reduced patients' pain (SMD: −1.86, 95% CI: −2.47 to −1.25, p < 0.001) of burn patients when compared with the control group. This study showed that PRP is effective in repairing burn wounds, promoting wound healing, reducing the incidence of adverse events and reducing patient pain, making it worthy of clinical promotion and application.
Currently, there are two methods of treating subtrochanteric femur fractures: intramedullary nailing and extramedullary plate fixation. However, it remains to be seen whether internal or external fixation is the primary treatment for subrotator femur fractures in adults. In this meta-analysis, we reviewed the effects of internal and external fixation on the treatment of subrotator and subrotator fractures. Until July 2023, the researchers have been researching the Cochrane Library, Embase, Web of Science and PubMed, with English as their only language. The aims of the study are as follows: (1) to assess the efficacy of internal and external fixation for the treatment of postoperative wound infections in adult patients with subrotator femur fractures; (2) to assess the efficacy of various types of internal fixation for the treatment of adult patients with subrotator femur fractures, including postoperative complications, infections, and operative time. Meta-analysis showed that there was no significant difference in the treatment of subrotator fracture with internal versus external fixation in terms of wound infections, intra-operative bleeding, length of incision, and operative time were not significantly different. Therefore, more research is needed to support these findings with a number of large, high-quality randomized studies.
Ultrasound (US) has traditionally been recognised for its imaging capabilities, but its emerging role as a therapeutic modality in postoperative wound management, especially in paediatric care, has garnered significant attention. This meta-analysis aimed to evaluate the influence of US on postoperative wound healing and infection rates in paediatric patients. From an initial pool of 1236 articles, seven were deemed suitable for inclusion. Postoperative wound healing was assessed using the Redness, Edema, Ecchymosis, Discharge, and Approximation (REEDA) scale. Notably, there was a significant difference in wound healing patterns between the US-treated and control groups (I 2 = 94%, standardized mean difference [SMD]: −4.60, 95% confidence intervals [CIs]: −6.32 to −2.88, p < 0.01), as illustrated in Figure 4. Additionally, a marked difference in wound infection rates was observed between the groups (I 2 = 93%, SMD: −5.86, 95% CIs: −9.04 to −2.68, p < 0.01), as portrayed in Figure 5. The findings underscore the potential benefits of US in enhancing postoperative wound healing and reducing infection rates in paediatric surgical settings. However, the application of US should be judicious, considering the nuances of individual patient needs and clinical contexts.
Diabetic foot ulcers (DFUs) are one of the most common and challenging complications of diabetes, yet our understanding of their pathogenesis remains limited. We collected gene expression data of DFU patients from public databases. Bioinformatics tools were applied for systematic analysis, including the identification of differentially expressed genes (DEGs), weighted gene co-expression network analysis (WGCNA) and enrichment analysis. We further used single-cell RNA sequencing to identify the distribution of different cell populations in DFU. Finally, key results were validated using reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and flow cytometry. We identified 217 DEGs between ulcerated and healthy skin, and 37 DEGs between healing ulcers and ulcers. WGCNA revealed that the cyan module had the highest positive correlation with healthy skin and negative correlation with ulcers. The black module had the highest negative correlation with healthy skin and positive correlation with ulcers. Enrichment analysis showed that the genes in the cyan module were mainly associated with complement and coagulation cascades, while the genes in the black module were mainly associated with the IL-17 signalling pathway. In addition, CD8 T cells were significantly lower in ulcers than in healthy and healing ulcers. By comparing marker genes of CD8 T cells, we identified key genes in the cyan and black modules and validated their expression using RT-qPCR. The proportion of CD8 T cells was increased in healing ulcers. Flow cytometry detected increased levels of CD8 T, B and natural killer cells in healing ulcers. CD8 T cells and related key genes play an important role in the healing process of DFU. The results of this study provide a new perspective for understanding the pathogenesis and treatment of DFU.
Diabetic foot ulcer (DFU) complications involve autophagy dysregulation. This study aimed to identify autophagy-related bioindicators in DFU. Differentially expressed genes (DEGs) between DFU and healthy samples were analysed from the Gene Expression Omnibus (GEO) datasets, GSE7014 and GSE29221. The roles of autophagy-related DEGs were investigated using protein–protein interaction (PPI) networks, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways, Gene Ontology (GO) enrichment, and Gene Set Enrichment Analysis (GSEA). Immune cell infiltration's correlation with these DEGs was also assessed. From the Human Autophagy Database (HADB), 232 autophagy-related genes (ARGs) were identified, with an intersection of 17 key DEGs between GSE7014 and GSE29221. These genes are involved in pathways like autophagy–animal, NOD-like receptor signalling, and apoptosis. In the protein network, epidermal growth factor receptor (EGFR) and phosphatase and tensin homologue (PTEN) showed significant interactions with ARGs. Survival analysis indicated the prognostic importance of calpain 2 (CAPN2), integrin subunit beta 1 (ITGB1), and vesicle-associated membrane protein 3 (VAMP3). Lower immune scores were observed in the type 2 diabetes mellitus (DM2) group than in controls. Autophagy and ARGs significantly influence DFU pathophysiology.
We aimed to quantitatively and systematically elucidate the rationality of the examined variables as independent risk factors for sternal wound infection. We searched databases to screen studies, ascertained the variables to be analysed, extracted the data and applied meta-analysis to each qualified variable. Odds ratios and mean differences were considered to be the effect sizes for binary and continuous variables, respectively. A random-effects model was used for these procedures. The source of heterogeneity was evaluated using a meta-regression. Publication bias was tested by funnel plot and Egger's test, the significant results of which were then calculated using trim and fill analysis. We used a sensitivity analysis and bubble chart to describe their robustness. After screening all variables in the eligible literature, we excluded 55 because only one or no research found them significant after multivariate analysis, leaving 33 variables for synthesis. Two binary variables (age over 65 years, NYHA class >2) and a continuous variable (preoperative stay) were not significant after the meta-analysis. The most robust independent risk factors in our study were diabetes mellitus, obesity, use of bilateral internal thoracic arteries, chronic obstructive pulmonary disease, prolonged surgery time, prolonged ventilation and critical preoperative state, followed by congestive heart failure, atrial fibrillation, renal insufficiency, stroke, peripheral vascular disease and use of an intra-aortic balloon pump. Relatively low-risk factors were emergent/urgent surgery, smoking, myocardial infarction, combined surgery and coronary artery bypass grafting. Sternal wound infection after open-heart surgery is a multifactorial disease. The detected risk factors significantly affected the wound healing process, but some were different in strength. Anything that affects wound healing and antibacterial ability, such as lack of oxygen, local haemodynamic disorders, malnutrition condition and compromised immune system will increase the risk, and this reminds us of comprehensive treatment during the perioperative period.
The purpose of the meta-analysis was to evaluate and compare the prevalence of surgical site infection (SSI) after spine surgery (SS) in nasal colonization of methicillin-resistant Staphylococcus aureus (MRSA). 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, 14 examinations spanning from 2014 to 2022 were included, encompassing 18 410 people who were tested for nasal colonization after SS. MRSA-positive had a significantly higher SSI (OR, 3.65; 95% CI, 2.48–5.37, p < 0.001) compared with MRSA-negative in SS subjects. However, no significant difference was found between methicillin-susceptible Staphylococcus aureus and Staphylococcus aureus negative (OR, 0.94; 95% CI, 0.32–2.79, p = 0.91), and Staphylococcus aureus positive and negative (OR, 2.13; 95% CI, 0.26–17.41, p = 0.48) in SS subjects. The examined data revealed that MRSA colonization had a significant effect on SSI; however, methicillin-susceptible Staphylococcus aureus and Staphylococcus aureus had no significant effect on SSI in SS subjects. However, given that some comparisons included a small number of chosen studies, attention should be given to their values.
Pressure injury (PrI) prevention guidelines recommend 2-h repositioning intervals in healthcare settings, requiring significant nursing time investment. We analysed the cost-effectiveness of PrI prevention protocols with 2-, 3- and 4-h repositioning intervals in US nursing homes according to ‘Turn Everyone and Move for Ulcer Prevention’ (TEAM-UP) randomized controlled trial findings. Markov modelling compared 2-, 3- and 4-h repositioning intervals, controlling for other practice guidelines, to prevent PrIs in nursing home residents from a US health sector perspective over one year using TEAM-UP trial data for model structure, sampling and parameterization. Costs, captured in 2020 US dollars, and quality-adjusted life years (QALYs) were used to derive an incremental cost-effectiveness ratio and net monetary benefit (NMB) at $50 000/QALY-$150 000/QALY cost-effectiveness thresholds. Sensitivity analyses tested model uncertainty. Repositioning intervals between 3 and 4 h were cost-effective based on reduced costs at slightly lower QALYs than 2 h at a $50 000/QALY threshold, and the NMB of 4-h repositioning was also more efficient than at 3 h ($9610). Repositioning labour cost and prevention routines were among the most sensitive parameters. Sensitivity analyses demonstrated that 3- and 4-h intervals were cost-effective in over 65% of simulations at any cost-effectiveness threshold. Repositioning intervals of 3 to 4 h have potential to reduce nursing time costs without significant decrements in clinical benefits to nursing home residents. Clinical guidelines for PrI prevention should be updated to reflect TEAM-UP clinical and economic findings. Facilities can use cost-savings recuperated from nursing time to deploy to other patient safety priorities without seriously jeopardizing PrI safety.
It is still a matter of controversy whether percutaneous endoscopic gastrostomy(PEG) should be used prior to the operation for the purpose of feeding the patient with resectable oesophageal carcinoma (EC). Comparison was made between EC and preoperatively treated PEG and non-preoperative PEG. An extensive literature review has been conducted to determine the results about PEG and No-PEG trials. In this paper, we chose 4 papers out of 407 of them through a strict selection process. In this trial, there were 1027 surgical cases of oesophagus carcinoma, 152 with PEG pre-surgery and 875 without PEG. The total sample size ranged from 14 to 657. Two studies showed that there was no statistically significant difference in the occurrence of postoperative wound infection among PEG and No-PEG(OR, 1.03; 95% CI, 0.38, 2.80 p = 0.96), there was no statistical significance in the likelihood of anastomotic leak among PEG after surgery compared to No-PEG in 4 trials (OR, 1.13; 95% CI, 0.62–2.07 p = 0.69), and there were no statistical differences between PEG and No-PEG before operation on anastomotic stricture for esophagectomy(OR, 0.70; 95% CI, 0.31–1.56 p = 0.38). No wound or anastomosis complications were observed in the PEG group. Thus, PEG preoperatively is an effective and safe procedure without any harmful influence on gastrointestinal structure or anastomosing. It can be applied to patients with oesophagus carcinoma who have a high risk of undernutrition. Nevertheless, because of the limited number of randomized controlled trials in this meta-analysis, caution should be exercised in their treatment. More high-quality research involving a large sample is required to confirm the findings.
As medical technology continues to evolve, it becomes crucial to distinguish the outcomes of traditional versus modern surgical techniques. This was a retrospective cohort study, conducted to compare the wound infection rates and recovery outcomes between laparoscopic and open surgery (OS) in 180 patients. Participants were divided into laparoscopic (n = 105) and OS (n = 75) groups. Comprehensive data, including demographics, surgical details, and postoperative outcomes, were extracted. Wound infection rates, as measured by Wound Asepsis Score, were prioritized alongside recovery indicators such as duration of hospital stay and postoperative pain. The laparoscopic group had a mean operative time of 57.19 minutes, while the OS group required 85.10 ± 15.18 minutes (p < 0.05). Laparoscopic surgeries resulted in an average blood loss of 120.76 ± 13.3 mL compared to 170.01 ± 17.19 mL for OS (p < 0.05). The laparoscopic group had significantly reduced (p < 0.05) average hospital stays (2.1 ± 1.1 days) than the OS group (4.4 ± 2.1 days). Although the laparoscopic group had lower incidence of surgical site infection (4.76%) than the OS group (9.33%), this difference was not statistically significant (p > 0.05). On postoperative days 1, 3, and 7, the Visual Analog Scale assessment of pain in the laparoscopic group revealed significantly reduced pain (p < 0.05). Laparoscopic surgery appeared to offer distinct advantages over conventional open surgery, especially in terms of operative durations, recovery rates, and postoperative pain management. This study highlighted the potential of laparoscopic approaches for specific surgical interventions, as well as the importance of patient-specific surgical strategy decision-making.
Deep tissue injuries (DTIs) are a serious type of pressure injuries that mainly occur at the bony prominences and can develop rapidly, making prevention and treatment more difficult. Although consistent research efforts have been made over the years, the cellular and molecular mechanisms contributing to the development of DTIs remain unclear. More recently, ferroptosis, a novel regulatory cell death (RCD) type, has been identified that is morphological, biochemical and genetic criteria distinct from apoptosis, autophagy and other known cell death pathways. Ferroptosis is characterized by iron overload, iron-dependent lipid peroxidation and shrunken mitochondria. We also note that some of the pathological features of DTI are known to be key features of the ferroptosis pathway. Numerous studies have confirmed that ferroptosis may be involved in chronic wounds, including DTIs. Here, we elaborate on the basic pathological features of ferroptosis. We also present the evidence that ferroptosis is involved in the pathology of DTIs and highlight a future perspective on this emerging field, desiring to provide more possibilities for the prevention and treatment of DTIs.
Breast remodelling is a major therapeutic choice in radical mastectomy. Breast reconstruction is regarded as a promising option for the treatment of breast cancer. The purpose of this meta-analysis was to investigate the effect of Post mastectomy radiotherapy (PMRT) on postoperative wound complications in breast carcinoma. A comprehensive review of documents was conducted between the date of establishment and the 28th of August 2023. In all of the trials, patients were treated with breast cancer. The researchers chose 11 publications out of 8068 related studies. Two researchers examined these publications to satisfy the inclusion criteria. Among the 516 patients who had received radiation therapy in the course of the operation, 1772 had not received radiation therapy. The impact of radiation therapy and non-radiation therapy in breast cancer patients after breast reconstruction was reported in 8 studies, and the incidence of postoperative wound infection in non-radiation group was significantly lower (OR, 1.95; 95% CI, 1.26–3.02 p = 0.003). In nine studies, There is not considered to have achieved statistical significance between radiation therapy and non-radiation treatment for post-operation wound dehiscence in breast cancer patients who had received chemotherapy (OR, 1.61; 95% CI, 0.70–3.72 p = 0.27). The results of six trials demonstrated that radiation therapy and non-radiation therapy had no statistical significance on post-operation haemorrhage in breast cancer patients (OR, 1.02; 95% CI, 0.42–2.47 p = 0.96). The results of 7 trials demonstrated that radiation therapy and non-radiation therapy had no significant impact on the post-operation of skin necrosis (OR, 1.22; 95% CI, 0.66–2.28 p = 0.53). Two trials demonstrated that those without radiation therapy were less likely than those who received radiation therapy in skin contracture in patients (OR, 7.24; 95% CI, 1.80–29.10 p = 0.005). Regarding the incidence of wound infection and cutaneous contraction was higher in the radiation group.
Prostate cancer is one of the most common malignancies worldwide and the fifth leading cause of cancer deaths in men. With the rapidly increasing surgical rate of minimally invasive radical prostatectomy, there is still controversy about how to use a urinary catheter post-operatively. Thus, we attempted to compare the post-operative wound-related outcomes through a meta-analysis of urethral catheterisation (UC) versus suprapubic catheterisation (SPC) after minimally invasive radical prostatectomy. As of August 2023, the authors conducted systematic searches in databases such as PubMed, Embase, Web of Science and the Cochrane Library. The authors reviewed the relevant literature separately to determine comparisons between SPC and UC treatment after radical prostatectomy. A total of 395 subjects were enrolled in the five trials, met the eligibility criteria and were included in the meta-analysis. Data collection and analysis revealed significant differences in catheter bother to patients for surgical trauma (MD, 0.98; 95% CI, 0.48, 1.48 p = 0.0001), with SPC causing less catheter bother to patients post-operatively; post-operative catheter-related problems (OR, 3.3; 95% CI, 0.03, 326.1 p = 0.61), the POD1 of the post-operative period (MD, − 0.09; 95% CI, −0.75, 0.94 p = 0.83) and the POD3 of the post-operative period (MD, −0.49; 95% CI, −0.99, 0.01 p = 0.06); there was no statistically significant difference in wound pain. Compared with UC, SPC patients had less post-operative catheter distress. Thus, SPC is more beneficial in reducing post-operative wound discomfort in patients. The validity of the results remains to be tested in more and better studies.
The purpose of the meta-analysis was to evaluate and compare the surgical site infection (SSI) risk factors in patients with colorectal cancer (CC). 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, 23 examinations spanning from 2001 to 2023 were included, encompassing 89 859 cases of CC. Clean-contaminated surgical site wounds had significantly lower infections (OR, 0.36; 95% CI, 0.20–0.64, p < 0.001) compared to contaminated surgical site wounds in patients with CCs. Males had significantly higher SSIs (OR, 1.18; 95% CI, 1.12–1.24, p < 0.001) compared to females in patients with CC. American Society of Anesthesiology score ≥3 h had a significantly higher SSI (OR, 1.42; 95% CI, 1.18–1.71, p < 0.001) compared to <3 score in patients with CCs. Body mass index ≥25 had significantly higher SSIs (OR, 1.54; 95% CI, 1.11–2.14, p = 0.01) compared to <25 in patients with CCs. The presence of stoma creation had a significantly higher SSI rate (OR, 2.28; 95% CI, 1.37–3.79, p = 0.001) compared to its absence in patients with CC. Laparoscopic surgery had significantly lower SSIs (OR, 0.68; 95% CI, 0.59–0.78, p < 0.001) compared to open surgery in patients with CC. The presence of diabetes mellitus had a significantly higher SSI rate (OR, 1.24; 95% CI, 1.15–1.33, p < 0.001) compared to its absence in patients with CCs. No significant difference was found in SSI rate in patients with CCs between <3 and ≥3 h of operative time (OR, 1.07; 95% CI, 0.75–1.51, p = 0.72), between the presence and absence of blood transfusion (OR, 1.60; 95% CI, 0.69–3.66, p = 0.27) and between the presence and absence of previous laparotomies (OR, 1.47; 95% CI, 0.93–2.32, p = 0.10). The examined data revealed that contaminated wounds, male sex, an American Society of Anesthesiology score ≥3 h, a body mass index ≥25, stoma creation, open surgery and diabetes mellitus are all risk factors for SSIs in patients with CC. However, operative time, blood transfusion and previous laparotomies were not found to be risk factors for SSIs in patients with CC. However, given that several comparisons had a small number of chosen research, consideration should be given to their values.
Wound care is a complex procedure and the related research may include many variables. Deficiencies in the sample inclusion and exclusion criteria may limit the generalizability of randomized controlled trials (RCTs) for wound patients in the real world. This study aimed to evaluate deficiencies in reporting the inclusion and exclusion criteria and the characteristics of patients in RCTs of pressure injuries (PI) therapeutic interventions. We conducted a systematic methodological review in which 40 full text RCTs of PI treatment interventions published in English, from 2008 to 2020, were identified. Data on the general characteristics of the included RCTs and data about inclusion/exclusion criteria and characteristics of patients were collected. The inclusion/exclusion criteria were categorized into five domains (definition of disease, precision, safety, ethical/legal and administrative). Study duration (in weeks) was 8.0 (quartile 1: 2.0; quartile 3: 48.0); only 5.0% of the trials mentioned race, skin colour or ethnicity, and 37.5% reported the duration of the wound. Only 9 (22.5%) studies reported the drugs that the included patients were using and 10 (25.0%) RCTs reported adverse events. The presence of the five domains was observed only in 12.5% of RCTs and only 12 (30.0%) had the precision domain. Much more research is required in systematic assessments of the external validity of trials because there is substantial disparity between the information that is provided by RCTs and the information that is required by clinicians. We concluded that there are deficiencies in reporting of data related to inclusion/exclusion criteria and characteristics of patients of RCTs assessing PI therapeutic interventions.
This study aimed to systematically evaluate the effects of clinical nursing on surgical site wound infections and postoperative complications in patients after undergoing total knee arthroplasty (TKA). Computerised searches of Embase, PubMed, Cochrane Library, China National Knowledge Infrastructure, VIP and Wanfang databases were conducted from inception to August 2023 to collect randomised controlled trials (RCTs) on patients with TKA who received clinical nursing pathway interventions. Literature screening, data extraction and quality assessment of the included studies were performed independently by two researchers. The meta-analysis was performed using Stata 17.0. A total of 14 RCTs with 1174 patients were included, including 587 patients each in the intervention and control groups. The meta-analysis results showed that the application of clinical nursing pathways to patients undergoing TKA significantly reduced surgical site wound infections (risk ratio [RR] = 0.28, 95% confidence interval [CI]: 0.15–0.54, p < 0.001) and postoperative complications (RR = 0.25, 95% CI: 0.17–0.37, p < 0.001). Therefore, clinical nursing pathway interventions in patients undergoing TKA should be promoted in clinical practice as they can effectively reduce the incidence of wound infection and postoperative complications.
Topical keloid therapy is performed with triamcinolone acetonide (TA) intralesional injection. However, the recurrence rate is high with various side effects. Mesenchymal stem cells (MSCs) have high proliferative abilities and reduce the activity and proliferation of fibroblast cells in keloids. To overcome the costs and limitations, conditioned medium (CM) is used. This study aims to evaluate feasibility of intralesional injection of umbilical cord MSC (UC-MSC) and conditioned medium (UC-CM) compared to TA for keloid therapy. Twenty-four patients with keloids who met the inclusion criteria were included, randomized into three treatment groups and then got assessed for the sociodemographic data, keloid volume, histopathology (type 1:3 collagen ratio), interleukin-10 (IL-10) levels and Patient and Observer Scar Assessment Scale (POSAS) score during visits. Largest volume regression occurred in the UC-MSC group, followed by UC-CM and then the TA group (UC-MSC: 45.32% ± 2.61%; UC-CM: 43.61% ± 3.67%; TA: 28.34% ± 3.81%; p = 0.003). Similar pattern was also observed in increase in IL-10 levels, the decrease in POSAS scores and the reduction of type 1:3 collagen ratio. Hence, UC-MSC and UC-CM are promisingly more effective than TA for keloid therapy, showcasing their superiority in reducing keloid volume, symptoms and type 1:3 collagen ratio, as well as increasing the levels of IL-10.
Surgical site infections (SSIs) post-surgery impact patient health and raise healthcare costs. This meta-analysis examines the efficacy of antiseptics, chlorhexidine and povidone–iodine, in reducing SSIs, including various types, to settle ongoing debates on their comparative effectiveness. A systematic literature search conforming to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines was executed on four established databases without temporal restrictions. Only randomized controlled trials (RCTs) including patients aged 18 years or older undergoing clean or potentially contaminated surgeries were included. Two independent evaluators carried out study selection, data extraction and quality assessment, adhering to Cochrane Collaboration's risk of bias tool. Statistical analyses were performed using chi-square tests and the I 2 index to evaluate heterogeneity, and meta-analyses were conducted employing either fixed-effects or random-effects models as warranted by the heterogeneity assessments. A total of 16 RCTs were included after rigorous selection from an initial pool of 1742 articles. The studies demonstrated low levels of heterogeneity, supporting the use of a fixed-effects model. Chlorhexidine exhibited statistically lower rates of overall SSIs (RR 0.75; 95% CI 0.64–0.88; p < 0.001), superficial SSIs (RR 0.62; 95% CI 0.47–0.82; p < 0.001) and deep SSIs compared to povidone–iodine. The study furnishes compelling evidence in favour of chlorhexidine as a more efficacious antiseptic agent over povidone–iodine in minimizing the risk of various types of SSIs.
