Meta-Analysis
OBJECTIVE
This study aims to assess the wound healing efficacy in second-degree burns in rats treated with 1% silver sulfadiazine (SSD)-a sulfonamide antibiotic.
METHOD
This is a systematic literature review and meta-analysis performed according to the PICO (Population, Intervention, Comparison and Outcomes) strategy.
RESULTS
The review found 100 studies in PubMed, Web of Science and other search engines. Of these, 70 studies were pre-selected after removing duplicates. After independent analysis by two reviewers, only seven studies met the inclusion criteria for meta-analysis. All studies except one showed faster wound closure by the application of silver sulfadiazine ointment. Using a random effects model, healing was faster in SSD-treated groups when compared to the control group on day 21, with a statistically significant mean difference of -2.72 days (95% confidence interval: -4.99, -0.45) between treatment and control groups (p<0.01).
CONCLUSION
The results of this meta-analysis revealed that SSD aided in faster healing of second-degree burns.

Review
The potential for developing new antimicrobial resistance from the use of medical devices containing chlorhexidine, minocycline, rifampicin and their combinations: a systematic review.
BACKGROUND
Catheter infections remain one of the most persistent adverse events causing significant morbidity, economic impact and mortality. Several strategies have been proposed to reduce these infections including the use of catheters embedded with antibiotics and/or antiseptics. One reoccurring challenge is the fear that antimicrobial medical devices will induce resistance. The aim of this systematic review is to evaluate the evidence for induced antimicrobial resistance caused by exposure to antimicrobial medical devices.
METHODS
Four electronic databases [MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature (CINAHL) and Scopus] were screened for studies published between 1983 and 2019 regarding assessment of microbial resistance with use of medical devices containing chlorhexidine, minocycline, rifampicin or combinations thereof. Development of new resistance, selection for tolerant organisms and 'no change in resistance' were assessed.
RESULTS
Forty-four publications, grouped by study type and stratified by drug assessed, were included for analyses. The majority of studies found no change in resistance after exposure to antimicrobial medical devices (13 , 2 , 20 clinical). Development of new resistance was commonly reported with the use of rifampicin as a single agent and only reported in one study assessing the minocycline/rifampicin combination (M/R); however, the increase in MIC was well below clinical relevance.
CONCLUSIONS
Emergence of new resistance to combinations of M/R, minocycline/rifampicin/chlorhexidine (M/R/CH) and chlorhexidine/silver sulfadiazine (CHXSS) was rare. No clinical trials confirmed its occurrence and some refuted it. The risk of development of new resistance to these antimicrobial combinations appears more fear-based than substantiated by clinical and experimental evidence but warrants continued surveillance.

Review
BACKGROUND
Hematological malignancies disturb the blood, lymph nodes, and bone marrow. Taking medications for treating opportunistic infections (OIs) in these individuals may enhance the risk of medication interaction as well as adverse drug reactions.
OBJECTIVE
This review aims to evaluate the effectiveness of nondrug interventions in reducing OIs among patients with hematological cancers.
METHODS
The PubMed, CENTRAL (Cochrane Central Register of Controlled Trials), and Embase databases were searched on December 26, 2022, for all randomized controlled trials (RCTs). The primary endpoint was OIs. The quality of included studies was assessed by the Cochrane Risk-of-Bias tool.
RESULTS
A total of 6 studies were included in this review with 4 interventions: (1) types of mouthwash received, (2) presence of coating on central venous catheters (CVCs), (3) use of well-fitted masks, and (4) types of diet consumed. The results were presented in 8 different comparisons: (1) chlorhexidine-nystatin versus saline mouth rinse, (2) chlorhexidine versus saline mouth rinse, (3) nystatin versus saline mouth rinse, (4) chlorhexidine silver sulfadiazine-coated CVCs versus uncoated catheters, (5) well-fitted masks versus no mask, (6) amine fluoride-stannous fluoride versus sodium fluoride mouthwash, (7) low-bacterial diet versus standard hospital diet, and (8) herbal versus placebo mouthwash. No clear differences were reported in any of the outcomes examined in the first 3 comparisons. There were also no clear differences in the rate of catheter-related bloodstream infection or insertion site infection between the use of chlorhexidine silver sulfadiazine-coated CVCs versus uncoated catheters in the patients. Further, no significant differences were seen between patients who used a well-fitted mask and those without a mask in the incidence of OI. The all-cause mortality and mortality due to OI were similar between the 2 groups. There was no clear difference in all-cause mortality, although common adverse effects were reported in patients who used sodium fluoride mouthwash compared with those using amine fluoride-stannous fluoride mouthwash. There was no evidence of any difference in the incidence of possible invasive aspergillosis or candidemia between patients who consumed a low-bacterial diet and a standard diet. For the last comparison, no significant difference was seen between patients who received herbal and placebo mouthwash.
CONCLUSIONS
Very limited evidence was available to measure the effectiveness of nondrug interventions in hematological cancers. The effectiveness of the interventions included in this review needs to be evaluated further in high-quality RCTs in a dedicated setting among patients with hematological malignancies.

Review
BACKGROUND
Choosing adequate topical antimicrobial agents in burn patients still represents a challenge. Therefore, this systematic review was conducted to compile and evaluate current recommendations in international clinical practice guidelines (CPGs) to develop more consistent clinical guidance.
METHODS
A systematic search for CPGs was conducted independently by two reviewers using PubMed, EMBASE, Google Scholar, and external citations. The quality of the selected CPGs was evaluated separately using the AGREE II instrument, and intraclass correlation coefficients were calculated. Statistical analysis was performed using R V 1.4.1 statistical software.
RESULTS
Eleven CPGs were included in the study. Most guidelines tend to recommend silver-containing dressings over antiseptics or antibiotics, regardless of the depth of the burn. Silver sulfadiazine is the most recommended topical antimicrobial in low-resource settings. An overall mean appraisal AGREE II score of 68.2% was obtained. The global intraclass correlation coefficient was 0.62 (95% confidence intervals 0.54-0.69), which corresponds to a substantial global concordance between both appraisers.
CONCLUSIONS
Great heterogeneity was found between recommendations and CPGs. The three determining factors considered to issue a recommendation were the clinical scenario, burn-wound depth, and burn severity. There is consensus among the guidelines to use topical antimicrobials as a tool to prevent infection, and most of these recommend the use of silver-containing dressings for most scenarios. However, there is currently no ideal topical antimicrobial agent that can be recommended for all clinical scenarios. The development of more consistent recommendations is warranted to standardize clinical practice.

Meta-Analysis
BACKGROUND
Silver sulfadiazine is commonly used to treat local burn wounds. Aquacel-Ag is a hydrogen fiber dressing containing ionic silver that reduces burn wound infection and promotes antimicrobial activity. It is necessary to compare the efficacy of the two in the healing of burns.
AIMS
The aim of this study was to systematically evaluate the effect of Aquacel-Ag on burn wound healing.
METHODS
A computerized search of CNKI, VIP, Wanfang, SinoMed, PubMed, Cochrane Library, EMbase, Science Direct, Web of Science, Wiley Online Library, and Open Access Library databases was performed from January 1, 2000 to December 31, 2021 for randomized controlled clinical trials. The trials on Aquacel-Ag dressing and silver sulfadiazine in the treatment of burns were selected. Meta-analysis was performed using Review Manager 5.0 software.
RESULTS
Eleven articles were finally included, with 794 burn patients. Meta-analysis results showed that compared with patients treated with silver sulfadiazine, burn patients treated with Aquacel-Ag dressing had shorter wound healing time [MD = -2.49, 95% CI (-5.64-0.65), p = 0.12], significantly lower tumor necrosis factor-α (TNF-α) level [MD = -0.52, 95% CI (-0.82-0.22), p = 0.0008], higher wound healing rate [MD = 8.41, 95% CI (3.39-13.43), p = 0.001], fewer dressing changes [MD = -3.27, 95% CI (-4.90-1.63), p < 0.0001].
CONCLUSION
Aquacel-Ag dressing can shorten wound healing time and effectively reduce inflammatory reactions in burn patients compared with silver sulfadiazine, but their safety still needs further exploration and analysis.

BACKGROUND
The safety profile of antimicrobials used during pregnancy is one important consideration in the decision on how to treat and provide postexposure prophylaxis (PEP) for plague during pregnancy.
METHODS
We searched 5 scientific literature databases for primary sources on the safety of 9 antimicrobials considered for plague during pregnancy (amikacin, gentamicin, plazomicin, streptomycin, tobramycin, chloramphenicol, doxycycline, sulfadiazine, and trimethoprim-sulfamethoxazole [TMP-SMX]) and abstracted data on maternal, pregnancy, and fetal/neonatal outcomes.
RESULTS
Of 13 052 articles identified, 66 studies (case-control, case series, cohort, and randomized studies) and 96 case reports were included, totaling 27 751 prenatal exposures to amikacin (n = 9), gentamicin (n = 345), plazomicin (n = 0), streptomycin (n = 285), tobramycin (n = 43), chloramphenicol (n = 246), doxycycline (n = 2351), sulfadiazine (n = 870), and TMP-SMX (n = 23 602). Hearing or vestibular deficits were reported in 18/121 (15%) children and 17/109 (16%) pregnant women following prenatal streptomycin exposure. First trimester chloramphenicol exposure was associated with an elevated risk of an undescended testis (odds ratio [OR] 5.9, 95% confidence interval [CI] 1.2-28.7). Doxycycline was associated with cardiovascular malformations (OR 2.4, 95% CI 1.2-4.7) in 1 study and spontaneous abortion (OR 2.8, 95% CI 1.9-4.1) in a separate study. First trimester exposure to TMP-SMX was associated with increased risk of neural tube defects (pooled OR 2.5, 95% CI 1.4-4.3), spontaneous abortion (OR 3.5, 95% CI 2.3-5.6), preterm birth (OR 1.5, 95% CI 1.1-2.1), and small for gestational age (OR 1.6, 95% CI 1.2-2.2). No other statistically significant associations were reported.
CONCLUSIONS
For most antimicrobials reviewed, adverse maternal/fetal/neonatal outcomes were not observed consistently. Prenatal exposure to streptomycin and TMP-SMX was associated with select birth defects in some studies. Based on limited data, chloramphenicol and doxycycline may be associated with adverse pregnancy or neonatal outcomes; however, more data are needed to confirm these associations. Antimicrobials should be used for treatment and PEP of plague during pregnancy; the choice of antimicrobials may be influenced by these data as well as information about the risks of plague during pregnancy.

Review
: Burns are a serious public health problem worldwide, causing high morbidity and mortality. This study aimed to compare two forms of treatment for partial skin burns and to determine whether one is superior to the other in terms of efficacy and benefits through a meta-analysis of randomized controlled trials. This article highlights the efficacy of tilapia skin in the treatment of burns. We performed a meta-analysis of 199 patients and highlighted the promising results that indicate the clinical relevance of this resource when we compared the cost of dressings with the daily need for dressing changes, healing potential, and reduction in pain level according to the VAS scale and reduced frequency of dressing changes. : A search of PubMed, Cochrane Central, and LILACS was performed to identify randomized controlled trials comparing tilapia skin and silver-based dressings for treating burns. Studies involving overlapping populations and animals were excluded. The outcomes of interest were complete re-epithelialization, decreased pain level, and dressing change. : Summarize the article's main findings. : Four randomized trials were included with a total of 199 patients with partial-thickness burns between the ages of 2 and 70 years. A total of 99 (49.74%) patients were treated with tilapia skin, and conventional treatment was used on 100 (50.25%) of the patients. Differences were found between the tilapia and silver-based treatments concerning re-epithelialization (MD -0.48; CI 95% -0.71 to -0.24; < 0.01; I2 = 0%), decreased pain level (MD -0.79; CI 95% -1.10 to -0.47; < 0.01; I2 = 0%), and dressing change outcome (MD -3.54; 95% CI -5.81 to -1.26; = 0.02; I2 = 97%).

Meta-Analysis Review
This study aims to evaluate the clinical effects of different blood derivatives on wound healing using network meta-analysis. PubMed, Embase, OVID, Web of Science, SCOPUS and Cochrane Central were searched to obtain studies about blood derivatives on wound healing until October 2023. R 4.2.0 and Stata 15.0 softwares were used for data analysis. Forty-four studies comprising 5164 patients were included. The results of network meta-analysis showed that the healing area from high to low was GF + ORCCB, ORCCB, GF, PRF, Unnas paste dressing, APG, PRP injection, PRP, PRP + thrombin gel, PPP, HPL, CT. The healing time from low to high was PRP + thrombin gel, GF, PRP, PC + K, PC, APG, PRF, CT, Silver sulfadiazine ointment. The number of patients cured from high to low was APG, PRP injection, PRP, Aurix, PRF, Leucopatch, HPL, Antimicrobial Ointment Dressing, CT, 60 μg/cm repifermin, 120 μg/cm repifermin, AFG, PPP. The order of analgesic effect from high to low was AFG, Aminogam gel, PRF, PRP, Oxidised oil, APG, GF, CT. The order of the number of wound infection cases from low to high is APG, 20 μg/cm repifermin, 60 μg/cm repifermin, PRP, LeucoPatch, CT, PPP, Antiseptic ointment dressing. Healing area: GF + ORCCB had the best effect; Healing time: PRP + thrombin gel took the shortest time. The number of cured patients and the reduction of wound infection: APG has the best effect. Analgesic effect: AFG has the best effect. More studies with large sample sizes are needed to confirm the above findings.

Burn injuries cause severe pain, infection risks, psychological distress, financial burdens, and mortality, necessitating effective care. Aloe vera, a traditional burn remedy, shows wound healing potential, but its analgesic effects and efficacy with varying burn severity are uncertain. This study aims to investigate aloe vera's impact on wound healing, pain management, and infection prevention in burn patients. A systematic search on PubMed, Embase, and CENTRAL was performed on 9th October 2023 for randomized controlled trials (RCTs). The risk of bias was examined using the Cochrane risk-of-bias tool (version 2), and the meta-analysis was carried out using a random-effects model. The primary outcome was wound healing time, with secondary outcomes examining pain severity and wound infection. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach was used to assess the quality of evidence for each outcome. Nine RCTs were included in the current study, of which six provided data on the primary outcome. Aloe vera significantly reduced mean wound healing time compared to other topicals [mean difference (MD) -3.76 days; 95% confidence interval (CI) -5.69 to -1.84]. Additionally, the meta-analysis of the secondary outcomes found no significant differences in pain reduction (MD -0.76 points; 95% CI -1.53 to 0.01) and wound infection risk (risk ratio 1.10; 95% CI 0.34 to 3.59) between aloe vera and control groups. In conclusion, aloe vera expedites wound healing in second-degree burn patients without increased infection risk compared to other antimicrobial agents. The analgesic effects on burn injuries remain uncertain.

PURPOSE
is a parasite that is widely distributed around the globe and can cause brain inflammation, particularly in immunosuppressed patients such as those diagnosed with human immunodeficiency virus (HIV). This paper reviews the efficacy of azithromycin and pyrimethamine combination therapy for cerebral toxoplasmosis in patients with HIV.
METHODS
The scope of the studies included in this review was limited from 1992 to 2022, with studies primarily being randomized, controlled clinical trials available on online scientific journal databases. The authors screened eligible records for review, removing those that did not fit the inclusion and exclusion criteria. The risk of bias of the extracted data was analyzed through the Cochrane risk-of-bias tool for randomized trials.
RESULTS
A broad search of major online databases such as PubMed, Medline, Google Scholar, and Cochrane using keywords, limit fields, and Boolean operators yielded 3,130 articles. After thoroughly screening the search results, two studies were included in this review. Results from the studies included in the review demonstrate that the combination therapy of azithromycin and pyrimethamine is favorable for cerebral toxoplasmosis. However, the net response is less effective than the standard treatment regimen (pyrimethamine and sulfadiazine).
CONCLUSION
The combination therapy of azithromycin and pyrimethamine is less effective than the standard treatment regimen for maintenance therapy for cerebral toxoplasmosis; thus, administering these medications for this indication must be met with caution.
