Review
PURPOSE
This review aims to explore and summarise current knowledge of indocyanine green (ICG) fluorescence application in metabolic and bariatric surgery (MBS) and assess its potential in improving patient safety.
METHODS
The review was prepared according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations. Evidence from PubMed, ScienceDirect and Ovid MEDLINE databases was independently screened in October 2022. The primary information and outcomes were the type of fluorescence application with potential patient benefit and the complication rate. The secondary outcomes consisted of the kind of dye, the application protocol, and the equipment used.
RESULTS
Thirteen publications were included, with six prospective observational studies, five case reports and two retrospective cohort studies and involved a total of 424 patients. The publications were categorized into four groups based on the method of fluorescence application. Sixty-six percent of the cases used fluorescence for LSG, 32.3% used it for RYGB, 1.2% for revisional surgery, 0.2% during removal of an adjustable gastric band, and 0.2% for LSG combined with Rossetti fundoplication. ICG was used on its own in the majority of studies, although in one case, it was used in combination with methylene blue. ICG administration protocols varied significantly. Complications occurred in three patients (0.71%): leaks were diagnosed in two cases, and one patient required a blood transfusion.
CONCLUSION
The most popular type of use is intraoperative assessment of the blood supply. ICG application may reduce the risk of complications, with potential benefits in detecting ischemia and leaks, searching for bleeding in areas inaccessible to endoscopy, and non-invasive hepatopathy evaluation.

Meta-Analysis Review
INTRODUCTION
Numerous approaches have been assigned to treat dyslipidemia (DLP). Turmeric/curcumin have been widely investigated with this regard. In the current study, we explored the effect of curcumin/turmeric supplementation on lipid profile.
METHODS
Online databases were searched up to October 2022. The outcomes included triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-c), high-density lipoprotein cholesterol (HDL-c), apolipoprotein B (Apo-B), and apolipoprotein A (Apo-A). We used the Cochrane quality assessment tool to evaluate the risk of bias. The effect sizes were estimated as weighted mean difference (WMD) and 95% confidence intervals (CIs).
RESULTS
Out of 4182 articles retrieved from the initial search, 64 randomized clinical trials (RCTs) were included in the study. Between-study heterogeneity was significant. Meta-analysis showed that turmeric/curcumin supplementation exerts statistically significant improvements on blood levels of TC (WMD = -3.99 mg/dL; 95% CI = -5.33, -2.65), TG (WMD = -6.69 mg/dL; 95% CI = -7.93, -5.45), LDL-c (WMD = -4.89 mg/dL; 95% CI = -5.92, -3.87), and HDL-c (WMD = 1.80 mg/dL; 95% CI = 1.43, 2.17). However, turmeric/curcumin supplementation was not associated with improvements in blood levels of Apo-A or Apo-B. The studies did not thoroughly address the issues of potency, purity, or consumption with other foods.
CONCLUSION
Turmeric/curcumin supplementation seems to be effective in improving blood levels of TC, TG, LDL-c, and HDL-c; but may not be capable of improving their pertinent apolipoproteins. Since the evidence was assessed to be low and very low concerning the outcomes, these findings should be dealt with caution.

BACKGROUND
Azo dyes are used in textiles and leather clothing. Human exposure can occur from wearing textiles containing azo dyes. Since the body's enzymes and microbiome can cleave azo dyes, potentially resulting in mutagenic or carcinogenic metabolites, there is also an indirect health concern on the parent compounds. While several hazardous azo dyes are banned, many more are still in use that have not been evaluated systematically for potential health concerns. This systematic evidence map (SEM) aims to compile and categorize the available toxicological evidence on the potential human health risks of a set of 30 market-relevant azo dyes.
METHODS
Peer-reviewed and gray literature was searched and over 20,000 studies were identified. These were filtered using Sciome Workbench for Interactive computer-Facilitated Text-mining (SWIFT) Review software with evidence stream tags (human, animal, in vitro) yielding 12,800 unique records. SWIFT Active (a machine-learning software) further facilitated title/abstract screening. DistillerSR software was used for additional title/abstract, full-text screening, and data extraction.
RESULTS
187 studies were identified that met populations, exposures, comparators, and outcomes (PECO) criteria. From this pool, 54 human, 78 animal, and 61 genotoxicity studies were extracted into a literature inventory. Toxicological evidence was abundant for three azo dyes (also used as food additives) and sparse for five of the remaining 27 compounds. Complementary search in ECHA's REACH database for summaries of unpublished study reports revealed evidence for all 30 dyes. The question arose of how this information can be fed into an SEM process. Proper identification of prioritized dyes from various databases (including U.S. EPA's CompTox Chemicals Dashboard) turned out to be a challenge. Evidence compiled by this SEM project can be evaluated for subsequent use in problem formulation efforts to inform potential regulatory needs and prepare for a more efficient and targeted evaluation in the future for human health assessments.

Meta-Analysis Review
Effects of curcumin/turmeric supplementation on liver function in adults: A GRADE-assessed systematic review and dose-response meta-analysis of randomized controlled trials.
INTRODUCTION
Liver conditions are major burdens upon health systems around the world. Turmeric /curcumin is believed to possess therapeutic features in ameliorating various metabolic disorders. In this systematic review and meta-analysis of the randomized controlled trials (RCTs), we examined the effect of turmeric/curcumin supplementation on some liver function tests (LFTs).
METHODS
We comprehensively searched online databases (i.e. PubMed, Scopus, Web of Science, Cochrane Library, and Google Scholar) from inception up to October 2022. Final outcomes included aspartate aminotransferase (AST), alanine aminotransferase (ALT), and gamma-glutamyl transferase (GGT). Weighted mean differences (WMDs) were reported. In case of between-study heterogeneity, subgroup analysis was conducted. Non-linear dose-response analysis was carried out to detect the potential effect of dosage and duration. The registration code is CRD42022374871.
RESULTS
Thirty-one RCTs were included in the meta-analysis. Turmeric/curcumin supplementation significantly reduced blood levels of ALT (WMD = -4.09 U/L; 95 % CI = -6.49, -1.70) and AST (WMD = -3.81 U/L; 95 % CI = -5.71, -1.91), but not GGT (WMD: -12.78 U/L; 95 % CI: -28.20, 2.64). These improvements, though statistically significant, do not ensure clinical effectiveness.
CONCLUSION
It seems that turmeric/curcumin supplementation might be effective in improving AST and ALT levels. However, further clinical trials are needed to examine its effect on GGT. Quality of the evidence across the studies was low for AST and ALT and very low for GGT. Therefore, more studies with high quality are needed to assess this intervention on hepatic health.

Review
This review article describes studies published over the past five years on the combination of polyphenols, which are the most studied in the field of anticancer effects (curcumin, quercetin, resveratrol, epigallocatechin gallate, and apigenin) and chemotherapeutics such as cisplatin, 5-fluorouracil, oxaliplatin, paclitaxel, etc. According to WHO data, research has been limited to five cancers with the highest morbidity rate (lung, colorectal, liver, gastric, and breast cancer). A systematic review of articles published in the past five years (from January 2018 to January 2023) was carried out with the help of all Web of Science databases and the available base of clinical studies. Based on the preclinical studies presented in this review, polyphenols can enhance drug efficacy and reduce chemoresistance through different molecular mechanisms. Considering the large number of studies, curcumin could be a molecule in future chemotherapy cocktails. One of the main problems in clinical research is related to the limited bioavailability of most polyphenols. The design of a new co-delivery system for drugs and polyphenols is essential for future clinical research. Some polyphenols work in synergy with chemotherapeutic drugs, but some polyphenols can act antagonistically, so caution is always required.

Meta-Analysis
OBJECTIVE
To evaluate safety and efficacy of dietary polyphenols in the treatment of rheumatoid arthritis (RA).
METHODS
CNKI, Pubmed, Cochrane library, Embase were searched to collect randomized controlled trials (RCTs) of dietary polyphenols in the treatment of RA. The databases were searched from the time of their establishment to November 8nd, 2022. After 2 reviewers independently screened the literature, extracted data, and assessed the risk of bias of the included studies, Meta-analysis was performed using RevMan5.4 software.
RESULTS
A total of 49 records (47 RCTs) were finally included, involving 3852 participants and 15 types of dietary polyphenols (Cinnamon extract, Cranberry extract, Crocus sativus L. extract, Curcumin, Garlic extract, Ginger extract, Hesperidin, Olive oil, Pomegranate extract, Puerarin, Quercetin, Resveratrol, Sesamin, Tea polyphenols, Total glucosides of paeony). Pomegranate extract, Resveratrol, Garlic extract, Puerarin, Hesperidin, Ginger extract, Cinnamon extract, Sesamin only involve in 1 RCT. Cranberry extract, Crocus sativus L. extract, Olive oil, Quercetin, Tea polyphenols involve in 2 RCTs. Total glucosides of paeony and Curcumin involve in more than 3 RCTs. These RCTs showed that these dietary polyphenols could improve disease activity score for 28 joints (DAS28), inflammation levels or oxidative stress levels in RA. The addition of dietary polyphenols did not increase adverse events.
CONCLUSION
Dietary polyphenols may improve DAS28, reduce C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR), and improve oxidative stress, etc. However, more RCTs are needed to verify or modify the efficacy and safety of dietary polyphenols.

Meta-Analysis
BACKGROUND
Radiation dermatitis (RD) is a common side effect of radiotherapy in most breast cancer patients. Curcumin has recently attracted more attention for managing the side effects of breast cancer treatments. This review study aimed to investigate the effect of curcumin on the severity of radiation dermatitis in patients with breast cancer. Methods: All eligible randomized controlled trials (RCTs) were collected by searching PubMed, Scopus, Cochrane, and Web of Science. The effect size was expressed as weighted mean difference (WMD) and 95% confidence interval (CI). Study heterogeneity was assessed through Q statistics and I-squared.
RESULTS
Four RCTs with 882 patients were included in the final analysis. The results of the meta-analysis indicated that curcumin supplementation significantly reduced radiation dermatitis severity (RDS) score in the intervention group compared to the control group (WMD=-0.50; 95% CI -0.72 to -0.27, P <0.001). A significant heterogeneity was observed between the studies (I2 = 95.7%, P < 0.001).
CONCLUSION
Based on the results of the present study, curcumin has significant effects in reducing the severity of radiation dermatitis in breast cancer patients receiving radiotherapy. Further well-designed longitudinal studies are recommended to confirm these results and to discover the underlying mechanisms of the effects of curcumin on the severity of radiation dermatitis in patients with cancer.

BACKGROUND
Port wine stains (PWS) often cause cosmetic effects and psychological distress. Pulsed dye lasers (PDL) and photodynamic therapy (PDT) are the most commonly used treatments. PDL is still the "gold standard" of therapy to date. However, its shortcomings have become apparent as clinical applications have increased. PDT has been proven as an alternative to PDL. Patients with PWS still lack enough evidence about PDT to make informed treatment decisions.
OBJECTIVE
The purpose of this systematic review and meta-analysis was to assess the safety and effectiveness of PDT for PWS.
METHODS
The online datasets, comprising PubMed, Embase, Web of Science, and the Cochrane Library, were searched for meta-analysis-relevant publications. Two reviewers separately evaluated the risk of bias in each listed study. Grading of Recommendations Assessment, Development, and Evaluation (GRADE) was used to assess the treatment and safety outcomes.
RESULTS
Our search retrieved 740 hits and only 26 studies were finally included. Among the 26 studies included, 3 were randomized clinical trials, and 23 were prospective or retrospective cohort investigations. Based on a gathered assessment, the percentage of individuals achieving a 60% improvement was estimated to be 51.5% [95% confidence interval (CI): 38.7-64.1; = 83.8%] and a ≥75% improvement was 20.5% (95% CI: 14.5-26.5; = 78.2%) after 1-8.2 treatment sessions (GRADE score: very low). Due to the statistical diversity of the meta-analysis, a subgroup assessment was performed to determine the sources of diversity. The collected findings indicated that the impact of PDT on enhancing the medical effectiveness of PWS was significant in different treatment sessions, different types of ages, different locations of PWS, and different types of PWS. Pain and edema occurred in most patients. Hyperpigmentation was present in 7.9-34.1% of the patients in 17 studies. Photosensitive dermatitis, hypopigmentation, blister, and scar were infrequently reported, with 0-5.8% incidences.
CONCLUSION
Photodynamic therapy is recommended as a safe and effective treatment for PWS based on the current evidence. However, our findings are based on poor-quality evidence. Therefore, comparative investigations of a large scale and high quality are necessary to support this conclusion.

This systematic review, conducted according to the PRISMA guidelines, focuses on genotoxicity of oxidative hair dye precursors. The search for original papers published from 2000 to 2021 was performed in Medline, Web of Science, Cochrane registry, Scientific Committee on Consumer Safety of the European Commission and German MAK Commission opinions. Nine publications on genotoxicity of -phenylenediamine (PPD) and toluene-2,5-diamine (-toluylenediamine; PTD) were included, reporting results of 17 assays covering main genotoxicity endpoints. PPD and PTD were positive in bacterial mutation assay, and PPD tested positive also for somatic cell mutations in the Rodent assay . Clastogenicity of PPD and PTD was revealed by chromosomal aberration assay. The alkaline comet assay showed DNA damage after PPD exposure, which was not confirmed where PTD exhibited positive results. PPD induced micronucleus formation , and increased micronucleus frequencies in mice erythrocytes following high dose oral exposure . Based on the results of a limited number of data from the classical genotoxicity assay battery, this systematic review indicates genotoxic potential of hair dye precursors PPD and PTD, which may present an important health concern for consumers and in particular for professional hairdressers.

Meta-Analysis
The effect of antioxidants supplementation on oxidative stress and proinflammatory biomarkers in patients with chronic kidney disease: a systematic review and meta-analysis.
OBJECTIVE
This systematic review and meta-analysis aimed to address the effect of antioxidant supplementation on oxidative stress and proinflammatory biomarkers in patients with Chronic Kidney Disease (CKD).
MATERIALS AND METHODS
Systematic literature searches from the date of inception up to September 16th, 2022, were performed on PubMed, SCOPUS, and the Cochrane Central Register of Controlled Trials using relevant keywords, i.e., "Chronic Kidney Disease" and "antioxidants", and "supplementation". All studies relevant to the selection criteria were included in the analysis, focusing on any type of oxidative stress and proinflammatory biomarkers. A meta-analysis of included literature was conducted if sufficient data was obtained.
RESULTS
This systematic review involved 32 published studies, with most having a Jadad score of ≥ 3 (65.6%). Only studies on antioxidants, i.e., polyphenols (n=5) and vitamin E (n=6) in curcumin/turmeric, were sufficient to be included in a meta-analysis. Curcumin/turmeric supplementation was found to significantly reduce the serum c-reative protein (CRP) [standardized mean difference (SMD) -0.5238 (95% CI: -1.0495, 0.0019); p = 0.05; I2 = 78%; p = 0.001]. Similarly, vitamin E supplementation was found to significantly reduce the serum CRP [SMD -0.37 (95% CI: -0.711, -0.029); p = 0.03; I2= 53%; p = 0.06] , but not serum interleukin-6 (IL-6) [SMD -0.26 (95% CI: -0.68, 0.16); p = 0.22; I2 = 43%; p = 0.17] and malondialdehyde (MDA) content [SMD -0.94 (95% CI: -1.92, 0.04); p = 0.06; I2= 87%; p = 0.0005].
CONCLUSIONS
Our review suggests that curcumin/turmeric and vitamin E supplements effectively lower serum CRP levels in CKD patients, particularly those undergoing chronic dialysis (CKD-5D). Higher scales of randomized controlled trials (RCTs) are still needed for other antioxidants due to inconclusive and contradicting results.
