Review
Surgical site infections (SSIs) pose a significant clinical challenge, with heightened risks and severe consequences for diabetic patients undergoing surgical procedures. This systematic review aims to synthesize the current evidence on effective prevention strategies for mitigating SSI risk in this vulnerable population. From inception to March 2024, we comprehensively searched multiple electronic databases (PubMed, Medline, Embase, Cochrane Library, CINAHL) to identify relevant studies evaluating SSI prevention strategies in diabetic surgical patients. Our search strategy followed Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines, utilizing a combination of keywords and Medical Subject Headings (MeSH) terms related to diabetes, surgical site infections, prevention strategies, and surgical procedures. Inclusion criteria focused on peer-reviewed clinical trials, randomized controlled trials, and meta-analyses published in English. The search yielded three studies meeting the eligibility criteria, subject to data extraction and qualitative synthesis. Key findings highlighted the efficacy of interventions such as optimized perioperative glycemic control, timely prophylactic antibiotic administration, and meticulous preoperative skin antisepsis in reducing SSI rates among diabetic surgical patients. The potential for personalized prevention approaches based on individual patient factors, such as diabetes type and surgical complexity, was explored. This systematic review underscores the importance of a multifaceted, evidence-based approach to SSI prevention in diabetic surgical patients, integrating strategies like glycemic control, antibiotic prophylaxis, and preoperative skin antisepsis. Furthermore, our findings suggest the potential benefits of personalized care pathways tailored to individual patient characteristics. Implementing these interventions requires interdisciplinary collaboration, adaptation to diverse healthcare settings, and patient engagement through culturally sensitive education initiatives. This comprehensive analysis informs clinical practice, fosters patient safety, and contributes to the global efforts to enhance surgical outcomes for this high-risk population.

Meta-Analysis Review
Guidelines for pre-operative skin antisepsis recommend using chlorhexidine in an alcohol-based solution. However, other antiseptics such as aqueous povidone-iodine or alcohol-based solutions continue to be used. Randomized controlled trials (RCTs) in caesarean section are rare and do not include all possible comparisons of antiseptics. The aim of this study was to assess the efficacy (reduction of surgical site infections) of chlorhexidine at two different concentrations (0.3% and 2%) and povidone-iodine in aqueous or alcohol-based solutions using a network meta-analysis, including only RCTs of caesarean sections. Fragility indices and prediction intervals were also estimated. A systematic literature review and network meta-analysis were performed. RCTs published up to February 2024 were collected from PubMed, ScienceDirect and the Cochrane Library. Interventions included alcohol-based povidone-iodine, aqueous povidone-iodine, and alcohol-based chlorhexidine 2% and 0.3%. The primary outcome measure was surgical site infection. Nine RCTs with 4915 patients and four interventions were included in the network meta-analysis. All credible intervals of the compared interventions overlapped. Alcohol-based 2% chlorhexidine had the highest probability of being effective in preventing surgical site infections, followed by alcohol-based povidone-iodine. The fragility index ranged from 4 to 18. The prediction intervals were wide. On the basis of rank probabilities, chlorhexidine 2% in an alcohol-based solution was most likely to be effective in preventing surgical site infections after caesarean section, followed by alcohol-based povidone-iodine. Given the paucity of literature and the relatively small difference between povidone-iodine and chlorhexidine found in our meta-analysis, we suggest that either can be used in an alcohol-based solution as antisepsis for planned or emergency caesarean section.

Review
Topical antimicrobials and antiseptics are used perioperatively to reduce the ocular surface bacteria flora (OSBF) that are involved in the development of post-operative infectious complications. However, their effectiveness is still a controversial topic. This systematic review, performed according to the PRISMA guidelines and registered in PROSPERO, aims to provide an overview of the efficacy of the agents currently used in peri-cataract surgery and -intravitreal injections (IVI) in lowering the OSBF. Although effective in lowering OSBF, perioperative topical antimicrobials are associated with the risk of resistance development, with no obvious additional benefit compared with topical antisepsis. Conversely, the effectiveness of topical antiseptics before cataract surgery and IVI is strongly supported. Based on the available evidence, perioperative antimicrobials are not recommended, whereas the perioperative use of antiseptics is strongly recommended as prophylactic treatment for lowering the infection due to OSBF. Post-operative antimicrobials may be considered in eyes at higher risk for infection.

Meta-Analysis Review
OBJECTIVE
Precesarean vaginal antisepsis can benefit pregnant women with ruptured membranes. However, in the general population, recent trials have shown mixed results in reducing postoperative infections. This study aimed to systematically review clinical trials and summarize the most suitable vaginal preparations for cesarean delivery in preventing postoperative infection.
DATA SOURCES
We searched PubMed, Web of Science, Cochrane Library, SinoMed databases, and the ClinicalTrials.gov clinical trials registry for randomized controlled trials and conference presentations (past 20 years, 2003-2022). Reference lists of previous meta-analyses were searched manually. In addition, we conducted subgroup analysis on the basis of whether the studies were conducted in developed or developing countries, whether the membranes were ruptured, and whether patients were in labor.
STUDY ELIGIBILITY CRITERIA
We included randomized controlled trials comparing vaginal preparation methods for the prevention of postcesarean infection with each other or with negative controls.
METHODS
Two reviewers independently extracted data and assessed the risk of bias and the certainty of the evidence. The effectiveness of prevention strategies was assessed by frequentist-based network meta-analysis models. The outcomes were endometritis, postoperative fever, and wound infection.
RESULTS
A total of 23 trials including 10,026 cesarean delivery patients were included in this study. Vaginal preparation methods included 19 iodine-based disinfectants (1%, 5%, and 10% povidone-iodine; 0.4% and 0.5% iodophor) and 4 guanidine-based disinfectants (0.05% and 0.20% chlorhexidine acetate; 1% and 4% chlorhexidine gluconate). Overall, vaginal preparation significantly reduced the risks of endometritis (3.4% vs 8.1%; risk ratio, 0.41 [0.32-0.52]), postoperative fever (7.1% vs 11.4%; risk ratio, 0.58 [0.45-0.74]), and wound infection (4.1% vs 5.4%; risk ratio, 0.73 [0.59-0.90]). With regard to disinfectant type, iodine-based disinfectants (risk ratio, 0.45 [0.35-0.57]) and guanidine-based disinfectants (risk ratio, 0.22 [0.12-0.40]) significantly reduced the risk of endometritis, and iodine-based disinfectants reduced the risk of postoperative fever (risk ratio, 0.58 [0.44-0.77]) and wound infection (risk ratio, 0.75 [0.60-0.94]). With regard to disinfectant concentration, 1% povidone-iodine was most likely to simultaneously reduce the risks of endometritis, postoperative fever, and wound infection.
CONCLUSION
Preoperative vaginal preparation can significantly reduce the risk of postcesarean infectious diseases (endometritis, postoperative fever, and wound infection); 1% povidone-iodine has particularly outstanding effects.

Meta-Analysis
Surgical site infection (SSI) is the most common complication of surgery, increasing healthcare costs and hospital stay. Chlorhexidine (CHX) and povidone-iodine (PVI) are used for skin antisepsis, minimising SSIs. There is concern that resistance to topical biocides may be emergeing, although the potential clinical implications remain unclear. The objective of this systematic review was to determine whether the minimum bactericidal concentration (MBC) of topical preparations of CHX or PVI have changed over time, in microbes relevant to SSI. We included studies reporting the MBC of laboratory and clinical isolates of common microbes to CHX and PVI. We excluded studies using non-human samples and antimicrobial solvents or mixtures with other active substances. MBC was pooled in random effects meta-analyses and the change in MBC over time was explored using meta-regression. Seventy-nine studies were included, analysing 6218 microbes over 45 years. Most studies investigated CHX (93%), with insufficient data for meta-analysis of PVI. There was no change in the MBC of CHX to Staphylococci or Streptococci over time. Overall, we find no evidence of reduced susceptibility of common SSI-causing microbes to CHX over time. This provides reassurance and confidence in the worldwide guidance that CHX should remain the first-choice agent for surgical skin antisepsis.

The Utility of Chlorhexidine Cloth Use for the Prevention of Surgical Site Infections in Total Hip Arthroplasty and Surgical as well as Basic Science Applications: A Meta-Analysis and Systematic Review.
Skin antisepsis, such as ready-to-use, no-rinse, 2% chlorhexidine-impregnated cloths, is one of the fundamental cornerstones for reducing periprosthetic infections after primary lower extremity total joint arthroplasties. This systematic review presents background material concerning the problem and methods to deal with and then describes the use of chlorhexidine cloth prophylaxis related to various surgical applications. The authors found an almost universal benefit of the cloths. In the meta-analysis, the total pooled effect showed a reduction in infection rates. The use of chlorhexidine cloths is appropriate for prophylaxis for knee arthroplasty, hip arthroplasty, and a variety of other surgeries.

Review
BACKGROUND
Improved patient safety (PS) in cosmetic breast surgery relies upon high-quality evidence. The objective of this study was to systematically review the existing evidence for PS and quality improvement (QI) in cosmetic breast surgery.
METHODS
A systematic review of published plastic surgery literature from 1965 to 2021 was undertaken through a computerized search following PRISMA guidelines. Publication descriptors, methodological details, and overall results were extracted. Articles were assessed for methodological quality using either the MINORS, Cochrane ROB2, or AMSTAR 2 instrument depending on the type of study.
RESULTS
Sixty studies were included. Most studies were retrospective, and 43.3 percent were from the 3rd level of evidence. Overall, the scientific quality was moderate, with randomized controlled trials and non-comparative non-randomized studies generally being rated of higher quality. Studies investigating approaches to antisepsis (38.3 percent) in cosmetic breast surgery indicated conflicting opinions on prophylactic antibiotics. Studies focusing on risk factor assessment tools (8.3 percent) held possible utility in identifying high-risk patients for cosmetic surgery. Studies assessing anesthesia in cosmetic breast surgery (5 percent) demonstrated a significant benefit to tumescent local anesthesia. Drains for decreasing hematoma and seroma (8.3 percent) largely showed no benefit.
CONCLUSIONS
Overall, PS and QI studies were of moderate quality and investigated numerous interventions. Our review identified a need for additional studies to decrease infection and other breast implant morbidities, specifically breast implant-associated anaplastic large cell lymphoma and capsular contracture.

BACKGROUND
Surgical site infections (SSIs) in children represent a common and serious postoperative complication. Surgical skin preparation is an essential preventive measure in every surgical procedure. The most commonly used antiseptic agents for surgical skin preparation are chlorhexidine gluconate and iodophors in alcohol-based solutions. In adult patients the use of chlorhexidine-containing antiseptic solutions for preoperative skin preparation has been advocated to reduce SSI rates. Our objective was to conduct a systematic literature review on use of antiseptic agents for surgical skin preparation in children less than 16 years of age.
METHODS
A systematic review of MEDLINE, EMBASE, CINAHL and CENTRAL was performed using both MeSH and free text terms and using the relevant Cochrane filter to identify full text randomized trials (RCTs) and comparative observational studies. Interventions of interest were the choice of main agent in antiseptic solutions (chlorhexidine/povidone-iodine/alcohol) compared with each other or with other antiseptic agents. Primary outcome was the reported rate of surgical site infections.
RESULTS
In total 8 studies were included in the review; 2 RCTs and 6 observational studies. Observational studies generally did not primarily investigate the association of different antiseptics with subsequent SSI. The identified randomised controlled trials included only 61 children in total, and were of low quality. Consequently, we did not conduct a formal meta-analysis. Since the publication of a comprehensive systematic review of perioperative measures for the prevention of SSI in 2016, no randomized controlled trials comparing antiseptic agents for surgical skin preparation in paediatric surgery have been conducted.
CONCLUSION
Robust evidence on the optimal skin antisepsis to reduce SSIs in children is lacking. Direct extrapolation of effects from trials involving adults is not appropriate as physiologic characteristics and risk factors for SSIs differ between adults and children. It is therefore essential to conduct high quality RCT investigating interventions to identify optimal measures to reduce SSI rates in children.

Review
OBJECTIVE
Suppurative chondritis is a potentially devastating complication of burns to the ear. The infection and inflammation can liquify cartilage, leading to significant aesthetic deformities which are difficult to treat. This article reviews published measures for preventing post-burn chondritis.
METHOD
A comprehensive search of all available literature up to September 2020 was performed, according to PRISMA guidelines, for studies assessing preventive measures for post-burn chondritis. Randomised controlled trials (RCT), cohort studies, case-control studies, case reports and series were eligible for inclusion.
RESULTS
A total of 10 studies, including one RCT and nine retrospective observational analyses, were included, incorporating 1369 patients with burns to the ear. The most common interventions were pressure avoidance (70%), daily cleansing (60%), topical mafenide acetate (60%) and targeted debridement (30%). Packages of measures which included pressure avoidance were the most effective, all of which achieved a chondritis incidence of <6%.
CONCLUSION
Low-level but strong published evidence suggests that important treatment principles include prevention by pressure relief, targeted debridement, prophylactic local antibiotics, local antisepsis and the avoidance of desiccation.

Meta-Analysis Review
BACKGROUND
The presence of oral microorganisms resistant to traditional treatment is increasing, thus a search for new therapies is needed. In this context, antimicrobial photodynamic therapy (aPDT) is an approach for the treatment of antibiotic resistant andnon resistant microorganisms. Therefore, the aim of the present study was to conduct a systematic review and meta-analysis of randomized clinical trials of aPDT for oral antisepsis against oral polymicrobial biofilms.
METHODS
PubMed, Science Direct, Scopus, SciELO, Lilacs, Cochrane Library and Embase databases were searched. In total, five articles were included for qualitative analysis and four articles were used for quantitative analyses. Bias assessment of the eligible articles was made using the RoB 2 criteria. Network meta-analysis was performed using the random-effect model. Subgroup's analysis was also conducted. The groups evaluated were aPDT, exposure to light only and no treatment at all (control group). The quality of evidence was assessed by CINeMA approach.
RESULTS
aPDT mediated by curcumin had significant results in the reducing bacterial load (0.31-0.49 log UFC/ I=0%) when compared with the control group. The included articles were classified as low risk of bias, despite biases detected by allocation and blinding. Moreover, quantitative analysis between aPDT and control group and between light and control group were classified with low risk of confidence rating, while the results from aPDT versus light were classified as moderate risk of confidence rating.
CONCLUSION
aPDT has significant efficacy for oral antisepsis, however more randomized clinical trials will be needed to validate the present results.
