Staining-Enhanced Peroxidase-Mimicking Gold Nanoparticles in Nano-ELISA for Highly Sensitive Detection of Klebsiella pneumoniae.

Klebsiella pneumoniae, a member of the family Enterobacteriaceae, is a rod-shaped, Gram-negative bacterium, mainly found in the hospital environment and medical tools. It is the leading cause of nosocomial infection, characterized by bloodstream infection, wound site infection, urinary tract infection, and sepsis, mostly in older adults, newborn infants, and immunocompromised patients. This present study demonstrated a novel diagnostic method for K. pneumoniae detection based on the gold nanozyme activity for the oxidation of 3,3',5,5'-tetramethylbenzidine (TMB) in the presence of H2O2. The nanozyme activity of AuNPs with staining enhancement was statistically three times higher than that of the bare AuNPs in solid absorption at 650 nm. Nano-ELISA with staining enhancement could detect as low as 102 CFUs/mL of K. pneumoniae concentration, as the cutoff value was determined to be 0.158, which boosted the sensitivity of the immunoreactions by up to 100-fold. The detection limit of our assays was 26.023 CFUs/mL, and the limit of quantification was 78.857 CFUs/mL. There was no cross-reaction against other bacteria, which proved the immunoassays' remarkable specificity for recognizing K. pneumoniae. Taken together, we successfully developed and optimized the highly sensitive and decently specific nano-ELISA strategy that might be applicable for detecting various other bacterial pathogens.

Impact of surgical site infection after open and laparoscopic surgery among paediatric appendicitis patients: A meta-analysis.

Operative site wound infection is one of the most frequent infections in surgery. A variety of studies have shown that the results of laparoscopy might be superior to those of an open procedure. Nevertheless, there is still a lack of clarity as to whether there is a difference between open and laparoscopy with respect to the occurrence of wound infections in different paediatric operations. In this review, we looked at randomized, controlled studies that directly measured the rate of wound infection following an appendectomy with a laparoscope. We looked up four main databases for randomized, controlled studies that compare the treatment of paediatric appendicitis with laparoscopy. The surgeries included appendectomy. Through our search, we have determined 323 related papers and selected five qualified ones to be analysed according to the eligibility criteria. Five trials were also assessed for the quality of the documents. In the 5 trials, there were no statistically significant differences in the incidence of post-operative wound infection among the paediatric appendectomy and the open-access group (odds ratio [OR], 0.63; 95% confidence interval [CI], 0.34-1.15, p = 0.13). The four trials did not show any statistically significant difference in abdominal abscesses among the laparoscopic and open-access treatment groups (OR, 1.64; 95% CI, 0.90-3.01, p = 0.11). The four trials did not reveal any statistically significant difference in operating time (mean difference, -4.36; 95% CI, -17.31 to 8.59, p = 0.51). In light of these findings, the use of laparoscopy as compared with the open-approach approach in paediatric appendectomies is not associated with a reduction in the risk of wound infection.

Influence of continuous nursing on surgical site wound infection and postoperative complication for colorectal cancer patients with stoma: A meta-analysis.

We systematically evaluated the effect of continuous nursing on surgical site wound infections and postoperative complications in colorectal cancer (CRC) patients with stomas. Computerised searches of Embase, PubMed, Cochrane Library, China National Knowledge Infrastructure and Wanfang databases were conducted to collect clinical studies on CRC patients receiving continuous nursing interventions after colorectal stoma surgery; the search period was from the establishment of each database to August 2023. Two researchers independently screened the literature, extracted the data and completed a literature quality assessment. The meta-analysis was performed using Stata 17.0 and included 20 studies with 1759 patients. The meta-analysis showed that continuous nursing significantly lowered the rates of surgical site wound infection (risk ratio [RR] = 0.24, 95% confidence interval [CI]: 0.14-0.43, p < 0.001) and postoperative complications (RR = 0.30, 95% CI: 0.23-0.39, p < 0.001) for CRC stoma patients compared with the control group. Therefore, continuous nursing intervention should be promoted for use in clinical care.

Effects of accelerated rehabilitation surgical care on the surgical site wound infection and postoperative complications in patients of lung cancer: A meta-analysis.

To comprehensively evaluate the effect of accelerated rehabilitation surgical care on perioperative wound infections and complications in patients undergoing lung cancer surgery. A comprehensive computerised search for randomised controlled trials (RCTs) of accelerated rehabilitative surgical care applied to patients undergoing lung cancer surgery was conducted using the Web of Science, PubMed, Cochrane Library, Embase, Wanfang and China National Knowledge Infrastructure databases from inception to September 2023. The literature was screened and evaluated by two investigators, and data were extracted from the final included literature. Stata software (version 17.0) was used for data analysis. Overall, 21 RCTs involving 2187 patients were included, including 1093 cases in the accelerated rehabilitation surgical care group and 1094 cases in the conventional care group. The analyses revealed that patients with lung cancer surgery who implemented accelerated rehabilitation surgical care were significantly less likely to develop postoperative wound infections (odds ratio [OR] = 0.29, 95% confidence interval [CI]: 0.17-0.49, p < 0.001) and postoperative complications (OR = 0.26, 95% CI: 0.20-0.34, p < 0.001) and shortened the hospital length of stay (standardised mean differences [SMD] = -1.93, 95% CI: -2.32 to -1.53, and p < 0.001) compared with conventional care. The effect of accelerated rehabilitation surgical care intervention in the perioperative period of lung cancer surgery patients is remarkable, as it can effectively reduce the incidence of wound infection and complications, shorten hospitalisation time and promote patient recovery.

Effect of rapid rehabilitation care on surgical site wound infection and pain in patients with intertrochanteric femoral fractures: A meta-analysis.

This study examines the effects of rapid rehabilitation on surgical site wound infections and pain in patients with intertrochanteric femoral fractures. A computerised search was conducted for randomised controlled trials (RCTs) on rapid rehabilitation care in patients undergoing surgery for intertrochanteric femoral fractures published in the China National Knowledge Infrastructure, China Biomedical Literature Database, Wanfang Database, VIP, PubMed, Embase, Cochrane Library and Web of Science. The search was conducted from the time of the database construction to August 2023. Two investigators independently performed literature screening, data extraction and quality assessment based on predefined inclusion and exclusion criteria. Meta-analysis was performed via RevMan 5.4 software. Encompassing 21 studies involving 2004 patients, with 1007 patients receiving rapid rehabilitation care and 997 receiving routine care, our analysis revealed that rapid rehabilitation care significantly reduced postoperative complications (odds ratio [OR] = 0.24, 95% confidence interval [CI]: 0.17-0.33, p < 0.001), wound infections (OR = 0.30, 95% CI: 0.14-0.65, p = 0.002) and hospital stay (mean difference [MD] = -5.23, 95% CI: -6.03 to -4.43, p < 0.001). Moreover, compared with routine care, it notably improved wound pain (MD = -1.51, 95% CI: -1.98 to -1.05, p < 0.001) in patients undergoing surgery for intertrochanteric femoral fractures. Our findings underscore the effectiveness of rapid rehabilitation care in reducing wound pain, postoperative complications and wound infections among patients with intertrochanteric femoral fractures.

Assessing the impact of obesity on full endoscopic spine surgery: surgical site infections, surgery durations, early complications, and short-term functional outcomes.

An increasing number of obese patients undergoing elective spine surgery has been reported. Obesity has been associated with a substantially higher number of surgical site infections and a longer surgery duration. However, there is a lack of research investigating the intersection of obesity and full endoscopic spine surgery (FESS) in terms of functional outcomes and complications. The aim of this study was to evaluate wound site infections and functional outcomes following FESS in obese patients. Patients undergoing lumbar FESS at the participating institutions from March 2020 to March 2023 for degenerative pathologies were included in the analysis. Patients were divided into obese (BMI > 30 kg/m2) and nonobese (BMI 18-30 kg/m2) groups. Data were collected prospectively using an approved smartphone application for 3 months postsurgery. Parameters included demographics, surgical details, a virtual wound checkup, the visual analog scale for back and leg pain, and the Oswestry Disability Index (ODI) as a functional outcome measure. A total of 118 patients were included in the analysis, with 53 patients in the obese group and 65 in the nonobese group. Group homogeneity was satisfactory regarding patient age (obese vs nonobese: 55.5 ± 14.7 years vs 59.1 ± 17.1 years, p = 0.25) and sex (p = 0.85). No surgical site infection requiring operative revision was reported for either group. No significant differences for blood loss per level (obese vs nonobese: 9.7 ± 16.8 ml vs 8.0 ± 13.3 ml, p = 0.49) or duration of surgery per level (obese vs nonobese: 91.2 ± 57.7 minutes vs 76.8 ± 39.2 minutes, p = 0.44) were reported between groups. Obese patients showed significantly faster improvement regarding ODI (-3.0 ± 9.8 vs 0.7 ± 11.3, p = 0.01) and leg pain (-4.4 ± 3.2 vs -2.9 ± 3.7, p = 0.03) 7 days postsurgery. This effect was no longer significant 90 days postsurgery for either ODI (obese vs nonobese: -11.4 ± 11.4 vs -9.1 ± 9.6, p = 0.24) or leg pain (obese vs nonobese: -4.3 ± 3.9 vs -3.5 ± 3.8, p = 0.28). The results highlight the effectiveness and safety of lumbar FESS in obese patients. Unlike with open spine surgery, obese patients did not experience significant increases in surgery time or postoperative complications. Interestingly, obese patients demonstrated faster early recovery, as indicated by significantly greater improvements in ODI and leg pain at 7 days after surgery. However, there was no difference in improvement between the groups at 90 days after surgery.

Comparative Study of Amoxicillin and Multiple Antibiotics in Caesarean Section

Background: Prophylactic antibiotic usage is important for preventing surgical site wound infections and related complications following caesarean delivery, which can lead to maternal morbidity, prolonged hospital stays, and increased treatment costs. Despite the recommendation for a single dose of preoperative antibiotic prophylaxis, clinicians are hesitant to adopt this approach due to variations in patient characteristics and concerns about aseptic techniques. Objective: To compare the efficacy of a single-antibiotic regimen versus multiple antibiotics in caesarean section procedures. Materials and Methods: It was a randomized clinical trial study. It was carried out in Obs and Gynae, North East Medical College, Sylhet, Bangladesh during the period of January 2022 to June 2022. The study included pregnant women above 34 weeks of gestation admitted to the hospital undergone elective or emergency caesarean delivery for singleton pregnancy. Total 92 sample patients with 46 patients in each group. Study involved two groups. Group A received Amoxicillin single antibiotic. Group B received multiple antibiotics. Statistical data calculations were done using Statistical Package for the Social Science (SPSS Inc., Version 25.0, Chicago, IL, USA) and Chi-square test was done. The p- value &lt;0.05 was considered significant. Results: There were 46 patients in each group. Baseline characteristics, indications for caesarean delivery, duration of operation, duration of hospital stay and difficulties were similar. Post- operative morbidities like wound infection did not differ significantly (P&gt;0.05). None of the women needed prolong hospital stay. Conclusion: The current study found no statistically significant difference in the outcome measures among the two study groups receiving different prophylactic regimens for caesarean delivery. Therefore, it can be concluded that both single and multiple antibiotics provide equally effective protection in reducing maternal .......

Effects of enhance recovery after surgery nursing program on the surgical site wound infection in patients undergoing laparoscopic hepatectomy for hepatocellular carcinoma: A meta-analysis.

Our study aimed to investigate the effects of an enhanced recovery after surgery (ERAS) nursing program on surgical site wound infections (SSWI) and postoperative complications in patients undergoing laparoscopic hepatectomy (LH) for hepatocellular carcinoma. Computer searches of the PubMed, Cochrane Library, Web of Science, Embase, China National Knowledge Infrastructure and Wanfang databases were conducted to gather randomised controlled trials (RCTs) that were published from inception to September 2023. The target studies evaluated the effects of the ERAS nursing program in patients undergoing LH for hepatocellular carcinoma. Two independent authors screened the literature, extracted the data and performed quality assessments. Dichotomous variables were analysed using odds ratios (ORs) and 95% confidence intervals (CIs), as effect analysis statistics. Stata software (version 17.0) was used for data analysis. Eleven RCTs with 765 patients were included, with 383 patients in the ERAS group and 382 in the control group. The results revealed that the incidence of SSWI (OR = 0.32, 95%CI:0.15-0.71, p = 0.004) and postoperative complications (OR = 0.23, 95%CI:0.15-0.34, p < 0.001) were both significantly reduced in the ERAS group, compared with the control group. The ERAS nursing program, when applied to patients undergoing laparoscopic hepatic cancer resection, can effectively reduce the incidence of SSWI and postoperative complications, thus promoting postoperative recovery.

Effects of an enhanced recovery after surgery nursing programme on surgical site wound infection and postoperative complications in patients undergoing total knee arthroplasty: A meta-analysis.

This meta-analysis aimed to investigate the effects of the enhanced recovery after surgery (ERAS) nursing program on surgical wound infection (SWI) and postoperative complications in patients undergoing total knee arthroplasty (TKA). The PubMed, Web of Science, Cochrane Library, Embase, China National Knowledge Infrastructure and Wanfang databases were searched from the date of establishment of the database until August 2023 for randomised controlled trials (RCTs) that assessed the effects of the ERAS nursing program on SWI and postoperative complications in patients undergoing TKA. The literature was screened, data were extracted by two independent investigators, and the literature quality was assessed using the methods recommended by the Cochrane Collaboration. Data analysis was performed using Stata 17.0 software. Nineteen RCTs with 1580 patients were included in the study. The meta-analysis results showed that the rates of SWI (odds ratio [OR] = 0.19, 95% confidence interval [CI]: 0.10-0.37, p < 0.001) and postoperative complications (OR = 0.18, 95% CI: 0.12-0.25, p < 0.001) were significantly lower in the ERAS intervention group than those in the control group. Therefore, ERAS intervention after TKA can significantly reduce the occurrence of SWI and postoperative complications. It has a remarkable rehabilitation effect and can be widely used in clinical settings.

Effects of rapid rehabilitation nursing model on surgical site wound infection and pain of patients with ovarian cancer: A meta-analysis.

To explore the effect of rapid rehabilitation nursing model on surgical site wound infection and pain of patients with ovarian cancer. Computer searches were performed on randomised controlled trials (RCTs) of rapid rehabilitation nursing model applied to ovarian cancer patients in PubMed, Cochrane Library, Embase, China National Knowledge Infrastructure (CNKI), China Biomedical Literature Database (SinoMed), VIP and Wanfang Database from the time each database was constructed to May 2023. Two researchers independently screened the literature, extracted data and completed an assessment of the quality of the literature based on the inclusion and exclusion criteria. Meta-analysis was performed using RevMan 5.4 software. The database was searched to obtain 255 articles, and 22 articles were finally included, containing 966 patients in the experimental group and 954 patients in the control group, for a total of 1920 patients. The results of the meta-analysis showed that, compared with other nursing models, the use of the rapid rehabilitation nursing model significantly reduced surgical site wound infections in patients with ovarian cancer (OR = 0.30, 95% CI: 0.15-0.61, p < 0.001) and the rate of post-operative complications (OR = 0.27, 95% CI: 0.19-0.38, p < 0.001) also reduced the patients' post-operative wound pain (MD = -0.70, 95% CI: -0.85 to -0.55, p < 0.001). The rapid rehabilitation nursing model applied to patients with ovarian cancer surgery can effectively reduce the rate of post-operative complications and wound infections, and it can also reduce the post-operative wound pain.

Effects of application of the clinical nursing pathway on surgical site wound infection and postoperative complication rates in patients with total knee arthroplasty: A meta-analysis.

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.

Effect of enhanced recovery after surgery nursing on the incidence of surgical site wound infection in older adults with hip fractures: A meta-analysis.

This meta-analysis evaluated the effect of enhanced recovery after surgery (ERAS) nursing on the incidence surgical site wound infection in older adults with hip fractures. The PubMed, Embase, the Cochrane Library, Web of Science, China Biomedical Literature Database, Wanfang, China National Knowledge Infrastructure, and VIP databases were searched from inception up to March 2023 for articles on randomized controlled trials (RCTs) on the effect of ERAS nursing on surgical site wound infection in older adults with hip fractures. Patients in the experimental group received ERAS nursing, and patients in the control group received conventional postoperative nursing. Two researchers independently completed literature screening and data extraction. The included articles were evaluated according to Cochrane quality assessment standards and the meta-analysis was conducted using Stata 17.0 software to calculate the effect sizes and their 95% confidence intervals (CIs). Twelve RCTs were included with 1117 patients, including 559 in the experimental group and 558 in the control group. In older adults with hip fractures, ERAS nursing reduced the risk of surgical site wound infection (odds ratio [OR]: 0.26, 95% CI: 0.11-0.58, p = 0.001) and postoperative complications (OR: 0.22, 95% CI: 0.14-0.33, p < 0.001), and reduced the length of hospital stay (mean difference: -4.04 days, 95% CI: -4.33 to -3.76 days, p < 0.001). In older adults with hip fractures, ERAS nursing reduces the incidence of surgical site infection and complications and shortens the length of hospital stay.

Effects of laparoscopic splenectomy on surgical site wound infection in patients with spleen rupture: A meta-analysis.

A meta-analysis was performed to compare the effects of laparoscopic splenectomy (LS) and open splenectomy (OS) for splenic rupture on postoperative surgical site wound infections and postoperative complications. A comprehensive computerised search was conducted for studies comparing LS with OS for the treatment of splenic rupture in the PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP, and Wanfang databases, with the search including studies published in any language between the creation of the databases and August 2023. Two researchers independently screened the literature and extracted the data. Literature quality was assessed using the Newcastle-Ottawa Scale, and the included data were collated and analysed using Stata 17.0 software for meta-analysis. Twenty-two studies involving 1545 patients were included. LS was superior to OS in the following aspects: reduced risk of postoperative surgical site wound infection (OR = 0.19, 95% CI: 0.11-0.34, p = 0.000), shortened hospital stay (standardised mean difference = -1.73, 95% CI: -2.05 to -1.40, p = 0.000), and reduced postoperative complication rate (OR = 0.22, 95% CI: 0.16-0.31, p = 0.000). Compared with OS, LS has a lower rate of postoperative wound infection, shorter hospital stay, and reduced rate of postoperative complications. LS is safe and effective for the treatment of splenic rupture and can be promoted clinically.

Prevalence of wound infections and postoperative complications after total elbow arthroplasty for rheumatoid arthritis: A meta-analysis.

This study aimed to systematically evaluate the prevalence of surgical site wound infections and postoperative complications after total elbow arthroplasty (TEA) in patients with rheumatoid arthritis (RA) for clinical research and application. Embase, PubMed, Cochrane Library, CNKI, VIP, CBM, and Wanfang databases were electronically searched to collect clinical studies on the application of TEA in the treatment of RA from inception to August 2023. Two independent researchers performed literature screening, data extraction, and quality assessment. A meta-analysis was performed using the R 4.3.1 software. Overall, 26 studies with a total of 2374 patients were included. The results of the meta-analysis revealed that after TEA in patients with RA, the prevalence of surgical site wound infections and postoperative complications was 3.37% (95% confidence interval [CI]: 2.68%-4.13%), and 31.63% (95% CI: 24.97%-38.28%), respectively. The prevalence of surgical site wound infections is low, whereas that of postoperative complications is high; thus, the safety of TEA remains debatable. Owing to limitations on the quality and number of included studies, the findings need to be verified in higher-quality studies.

Effectiveness of nursing intervention in the operating room to prevent pressure ulcer and wound infection in patients undergoing intertrochanteric fracture: A meta-analysis.

In this study, a meta-analysis was conducted to comprehensively assess the effectiveness of nursing intervention in the operating room to prevent pressure ulcers and wound infections in patients with intertrochanteric fractures. A computerised search of PubMed, Cochrane Library, Embase, China National Knowledge Infrastructure (CNKI), VIP Database of Chinese Technical Periodicals, and Wanfang databases was performed to identify randomised controlled studies (RCTs) on the effectiveness of nursing intervention in the operating room for patients undergoing intertrochanteric fractures from the time of construction of the respective databases to June 2023. Two researchers independently searched and screened the literature, extracted information and performed quality assessments of the included literature. The meta-analysis was performed using RevMan 5.4 software. Eighteen studies were finally included, including 1517 patients, with 757 in the intervention group and 760 in the control group. The results showed that nursing intervention in the operating room significantly reduced the incidence of postoperative pressure ulcers in patients with intertrochanteric femoral fractures compared to the control group (1.69% vs. 6.01%, odds ratio [OR]: 0.32, 95% confidence interval [CI]: 0.18-0.57, p < 0.001) and reduced the incidence of surgical site wound infection (1.00% vs. 6.15%, OR: 0.23, 95% CI: 0.11-0.50, p < 0.001). Current evidence suggests that nursing intervention in the operating room is superior to routine care in reducing the incidence of pressure ulcers and wound infections in patients with intertrochanteric fractures and that such interventions should be promoted for clinical use.

Effects of parasternal intercostal block on surgical site wound infection and pain in patients undergoing cardiac surgery: A meta-analysis.

This study aimed to assess the effect of parasternal intercostal block on postoperative wound infection, pain, and length of hospital stay in patients undergoing cardiac surgery. PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure, VIP, and Wanfang databases were extensively queried using a computer, and randomised controlled studies (RCTs) from the inception of each database to July 2023 were sought using keywords in English and Chinese language. Literature quality was assessed using Cochrane-recommended tools, and the included data were collated and analysed using Stata 17.0 software for meta-analysis. Ultimately, eight RCTs were included. Meta-analysis revealed that utilising parasternal intercostal block during cardiac surgery significantly reduced postoperative wound pain (standardised mean difference [SMD] = -1.01, 95% confidence intervals [CI]: -1.70 to -0.31, p = 0.005) and significantly shortened hospital stay (SMD = -0.40, 95% CI: -0.77 to -0.04, p = 0.029), though it may increase the risk of wound infection (OR = 5.03, 95% CI:0.58-44.02, p = 0.144); however, the difference was not statistically significant. The application of parasternal intercostal block during cardiac surgery can significantly reduce postoperative pain and shorten hospital stay. This approach is worth considering for clinical implementation. Decisions regarding its adoption should be made in conjunction with the relevant clinical indices and surgeon's experience.

Application of hypoxia-mesenchymal stem cells in treatment of anaerobic bacterial wound infection: wound healing and infection recovery.

Mesenchymal stromal cells, commonly referred to as MSCs, are a type of multipotent stem cells that are typically extracted from adipose tissue and bone marrow. In the field of tissue engineering and regenerative medicine, MSCs and their exosomes have emerged as revolutionary tools. Researchers are now devoting greater attention to MSCs because of their ability to generate skin cells like fibroblasts and keratinocytes, as well as their distinctive potential to decrease inflammation and emit pro-angiogenic molecules at the site of wounds. More recent investigations revealed that MSCs can exert numerous direct and indirect antimicrobial effects that are immunologically mediated. Collectively, these antimicrobial properties can remove bacterial infections when the MSCs are delivered in a therapeutic setting. Regardless of the positive therapeutic potential of MSCs for a multitude of conditions, transplanted MSC cell retention continues to be a major challenge. Since MSCs are typically administered into naturally hypoxic tissues, understanding the impact of hypoxia on the functioning of MSCs is crucial. Hypoxia has been postulated to be among the factors determining the differentiation of MSCs, resulting in the production of inflammatory cytokines throughout the process of tissue regeneration and wound repair. This has opened new horizons in developing MSC-based systems as a potent therapeutic tool in oxygen-deprived regions, including anaerobic wound infection sites. This review sheds light on the role of hypoxia-MSCs in the treatment of anaerobic bacterial wound infection in terms of both their regenerative and antimicrobial activities.

Effects of tourniquet on surgical site wound infection and pain after total knee arthroplasty: A meta-analysis.

The application of a tourniquet (TNQ) for haemostasis in total knee arthroplasty (TKA) is controversial and lacking systematic evaluation. This meta-analysis assessed relevant international data to quantitatively evaluate the implications of using TNQ in TKA, further guide clinical diagnosis and treatment, and improve postoperative outcomes. A comprehensive computerised search of PubMed, Embase, Cochrane Library, Chinese National Knowledge Infrastructure, VIP, and Wanfang databases was conducted to retrieve randomised controlled trials on the application of TNQ in TKA published from database inception to August 2023. The included data, ultimately comprising 1482 patients in 16 studies, were collated and subjected to meta-analysis using Stata 17.0 software. The results showed that the use of TNQ during TKA led to significantly higher rates of postoperative surgical site wound infection (3.96% vs. 1.79%, odds ratio: 2.15, 95% confidence intervals [CIs]: 1.11-4.16, p = 0.023) and wound pain scores on the first (standardised mean difference [SMD]: 0.65, 95% CI: 0.35-0.94, p < 0.001), second (SMD: 0.66, 95% CI: 0.01-1.31, p = 0.045), and third (SMD: 0.68, 95% CI: 0.31-1.05, pP < 0.001) day after the procedure. In conclusion, the application of TNQ in TKA increases the risk of postoperative surgical site wound infection and worsens short-term postoperative wound pain; therefore, TNQ should be used sparingly during TKA, or its use should be decided in conjunction with the relevant clinical indications and the surgeon's experience.

Effectiveness of chlorhexidine versus povidone-iodine for preventing surgical site wound infection: A meta-analysis.

A systematic evaluation was conducted to assess the efficacy of two disinfectants, chlorhexidine and povidone-iodine, as primary components in preventing surgical site infection (SSI). A comprehensive computerised search was performed in the PubMed, EMBASE, Web of Science, Cochrane Library, CNKI and Wanfang databases for randomised controlled trials (RCTs) on chlorhexidine and povidone-iodine disinfection for the prevention of SSI from inception until July 2023. Two independent researchers completed literature screening, data extraction and quality assessment of the included studies. The meta-analysis was conducted using RevMan 5.4 software. Ultimately, 20 RCTs were included, which included 13 133 patients, with 6460 patients in the chlorhexidine group and 6673 patients in the povidone-iodine group. The meta-analysis results revealed that the incidence rate of surgical site wound infections [odds ratio (OR): 0.67, 95% confidence interval (CI): 0.58-0.78, p < 0.001)], superficial SSI rate (OR: 0.59, 95% CI: 0.46-0.75, p < 0.001) and deep SSI rate (OR: 0.49, 95% CI: 0.31-0.79, p = 0.003) were all lower in patients subjected to chlorhexidine disinfection compared to those patients receiving povidone-iodine disinfection. Existing evidence suggests that chlorhexidine is more effective than povidone-iodine at preventing SSI. However, owing to the potential quality limitations of the included studies, further validation through high-quality large-scale RCTs is warranted.

Comparison of the effects of laparoscopic and open hysterectomy on surgical site wound infections in patients with endometrial cancer: A meta-analysis.

This meta-analysis aimed to compare laparoscopic hysterectomy (LH) and open hysterectomy (OH) in terms of surgical site wound infection, length of hospital stay, and postoperative complications in patients with endometrial cancer (EC). PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure, VIP, and Wanfang databases were comprehensively searched for studies on OH and LH for EC published between 2008 and July 2023, in any language. The literature was screened according to the inclusion and exclusion criteria, and the quality of the included case-control studies was assessed using the Newcastle-Ottawa Scale. Data were collated and analysed using Stata 17.0 software. A total of 1245 articles were screened according to the search strategy, and ultimately 15 studies were included in this meta-analysis, with a total of 1606 patients with EC, of which 751 were treated with LH and 855 with OH. The results showed that the rate of postoperative wound infection was significantly higher (OR: 0.290; 95% CI: 0.169-0.496, p < 0.001), the length of hospital stay was significantly longer (SMD: -1.976, 95% CI: -2.669 to -1.283, p < 0.001), and the incidence of postoperative complications was significantly higher (OR: 0.366; 95% CI: 0.280-0.478, p < 0.001) in the OH group than in the LH group. This study showed that LH was superior to OH for the treatment of EC and is associated with a lower rate of wound infection, shorter length of hospitalisation, and a reduced risk of complications. Thus, our findings support the choice of LH over OH for EC.
