Meta-Analysis
Effect of xanthophyll-rich food and supplement intake on visual outcomes in healthy adults and those with eye disease: a systematic review, meta-analysis, and meta-regression of randomized controlled trials.
CONTEXT
Xanthophyll intake is known to improve eye health; however, its benefits on visual outcomes have not been systematically studied, particularly in a population with eye diseases.
OBJECTIVE
A systematic review, meta-analysis, and meta-regression were conducted to investigate the effect of xanthophyll intake on visual outcomes, and further subgroup analysis was performed on the basis of eye disease status.
DATA SOURCES
The PubMed, Scopus, Embase, CINAHL, Cochrane, and Web of Science databases were searched, and relevant randomized controlled trials were identified.
DATA EXTRACTION
For systematic review, meta-analysis, and meta-regression, 43, 25, and 21 articles were selected, respectively.
DATA ANALYSIS
Xanthophyll intake enhanced macular pigment optical density (MPOD) for both heterochromatic flicker photometry (weighted mean difference [WMD], 0.05; 95% confidence interval [CI], 0.03-0.07) and autofluorescence imaging (WMD, 0.08; 95%CI, 0.05-0.11) measurements and decreased photostress recovery time (WMD, -2.35; 95%CI, -4.49 to -0.20). While enhancement in visual acuity logarithm of the minimum angle of resolution was observed in response to the xanthophyll-rich food and supplement intake only for patients with eye disease (WMD, -0.04; 95%CI, -0.07 to -0.01). Meta-regression showed a positive correlation between change in MPOD (heterochromatic flicker photometry) and the corresponding change in serum lutein levels (regression coefficient = 0.068; P = 0.00).
CONCLUSION
Intake of xanthophyll-rich food or supplements can improve eye health. Additional improvement in visual acuity was observed in patients with eye disease. A positive association between MPOD and serum lutein level, while absent with dietary xanthophyll intake, suggests the importance of bioavailability when examining the effect of xanthophyll on eye health.

Morbihan disease (MD) is considered a rare complication of rosacea, which is difficult to diagnose and challenging to treat. Here, we performed a systematic review of available case reports and case series to summarize key clinical and pathologic features of and successful treatment regimens for MD. We conducted a search of the PubMed/MEDLINE, EMBASE, and Cochrane electronic databases from their inception to the date of search on March 6, 2023. We found that MD affects patients in the fifth decade of life on average, more commonly reported in male than female (69% vs 31%). Clinically, MD affects the eyelids, cheeks, and forehead most commonly, presenting as non-pitting, erythematous edema or an edematous plaque. On biopsy, the pathologic features, such as dermal edema, sebaceous hyperplasia, perivascular and periadnexal inflammatory infiltrate, and granulomatous reaction, are frequently reported. Out of 55 patients who were able to achieve complete response without recurrence, 35% of patients were treated with isotretinoin and 22% were treated with tetracycline antibiotics with a daily dosage range of 20-80 mg and 40-200 mg, respectively. Out of those 55 patients, 22% and 7% were treated successfully with surgical intervention and intralesional injection of steroids, respectively. Additionally, lymphatic drainage has been shown to be an effective adjunctive therapeutic tool. More studies are necessary to understand the disease mechanism to improve the diagnosis of and develop evidence-based therapies for MD.

Meta-Analysis
BACKGROUND
Cases of inflammatory bowel disease (IBD) following isotretinoin use have been reported previously, but whether isotretinoin exposure is associated with IBD has been unclear.
OBJECTIVE
The aim was to evaluate whether isotretinoin use is associated with IBD.
METHODS
We performed a systematic review and searched MEDLINE, Embase, and CENTRAL databases from inception to January 27, 2023 for relevant case-control and cohort studies. Our outcome was the pooled odds ratio (OR) for IBD and its two subtypes (Crohn disease and ulcerative colitis) in relation to isotretinoin exposure. We conducted a random-effects model meta-analysis and a sensitivity analysis by excluding low-quality studies. A subgroup analysis was undertaken by including studies considering antibiotic use. A trial sequential analysis (TSA) was performed to test the robustness of the conclusiveness of our results.
RESULTS
We included eight studies (four case-control and four cohort studies) with a total of 2,522,422 participants. The meta-analysis found no increased odds for IBD among patients receiving isotretinoin (OR 1.01; 95% confidence interval [CI] 0.80-1.27). Nor did the meta-analysis find increased odds for either Crohn disease (OR 0.87; 95% CI 0.65-1.15) or ulcerative colitis (OR 1.27; 95% CI 0.94-1.73) associated with isotretinoin exposure. The sensitivity and subgroup analyses produced similar results. In TSA, the Z-curve reached the futility boundaries when using relative risk reduction thresholds ranging from 5% to 15%.
CONCLUSION
This meta-analysis with TSA found no evidence of an association of isotretinoin use with IBD. Isotretinoin should not be withheld because of unnecessary concerns for the development of IBD.

Meta-Analysis
OBJECTIVE
This study aimed to explore the relationship between the intake of vitamin C, vitamin E and β-carotene, and the risk of Parkinson's disease (PD).
METHODS
Web of Science, Embase, PubMed, Cochrane library, CNKI, and WanFang databases were searched from inception to 29 August 2022 for observational studies reporting the odds ratios (ORs) or relative risks (RRs) or hazard ratios (HRs) and 95% confidence intervals (CIs) of PD by Vitamin C/Vitamin E/β-carotene intake. Random-effects models, publication bias assessment, subgroup, sensitivity and dose-response analyses were performed, using.Stata version 12.0.
RESULTS
A total of 13 studies were included. There was no significant association between high-dose vitamin C intake and the risk of PD compared with low-dose vitamin C intake (RR = 0.98, 95%CI:0.89,1.08). Compared with low-dose intake, high-dose intake of vitamin E can prevent the risk of PD (RR = 0.87, 95%CI:0.77,0.99). Compared with lower β-carotene intake, there was a borderline non-significant correlation between higher intake and PD risk (RR = 0.91, 95%CI:0.82,1.01), and high dose β-carotene intake was found to be associated with a lower risk of PD in women (RR = 0.78, 95%CI:0.64,0.96).
CONCLUSION
This study shows that vitamin E intake can reduce the risk of PD and play a preventive role.

Meta-Analysis
CONTEXT
β-Carotene, which is derived from most fruits and vegetables, is the most common type of carotenes. Existing studies have demonstrated that β-carotene is associated with some positive health outcomes. However, results about the effects of supplemental β-carotene on cancer are inconsistent.
OBJECTIVE
To determine the association between supplemental β-carotene intake and the risk of cancers.
DATA SOURCES
Eight databases (PubMed, Web of Science, Embase, Cochrane, China National Knowledge Infrastructure, Wangfang, China Science and Technology Journal Database, and Chinese Biomedical Literature Database) were systematically searched until September 2022.
DATA EXTRACTION
Only reports from randomized controlled trials in which an association between supplemental β-carotene intake and the risk of cancer was found were included in the meta-analysis.
DATA ANALYSIS
A total of 18 eligible studies based on 8 different randomized controlled trials were included in the meta-analysis, with varying sample sizes from 391 to 39 876 participants. There was no significant association between supplemental β-carotene intake and overall cancer incidence rate after synthesizing all the results (risk ratio [RR]: 1.02; 95% confidence interval [CI], 0.99-1.05). Results from subgroup analysis indicated that intake of supplemental β-carotene significantly increased the risk of lung cancer (RR: 1.19; 95%CI: 1.08-1.32), whereas no significant associations were observed for other site-specific cancers. In addition, smokers and the subgroup of participants with only low-dose β-carotene intake had a risk increment of cancer if they took supplemental β-carotene (RR: 1.16; 95%CI: 1.05-1.29).
CONCLUSION
β-Carotene supplementation has no beneficial or harmful effect on cancer incidence; moreover, it might have potentially harmful effects on lung cancer, especially for people who smoke. On the basis of the evidence from this study, supplemental intake of β-carotene is not recommended for preventing cancer, and the establishment of a tolerable upper intake level of β-carotene should be considered.

The Annals of Pharmacotherapy Sep 2023To assess the efficacy, safety, and clinical application of tretinoin 0.1%-benzoyl peroxide 3% cream for the topical treatment of acne vulgaris. (Review)
Review
OBJECTIVE
To assess the efficacy, safety, and clinical application of tretinoin 0.1%-benzoyl peroxide 3% cream for the topical treatment of acne vulgaris.
DATA SOURCES
A systematic review of the literature was performed using the terms OR OR in MEDLINE (PubMed) and EMBASE. ClinicalTrials.gov was searched to obtain completed clinical trial results not published elsewhere.
STUDY SELECTION AND DATA EXTRACTION
All human studies published in English prior to November 2022 related to pharmacology, clinical trials, safety, and efficacy were evaluated for inclusion.
DATA SYNTHESIS
In two 12-week, phase 3, randomized, vehicle-controlled clinical trials, tretinoin 0.1%-benzoyl peroxide 3% cream significantly reduced inflammatory and noninflammatory facial acne lesions and significantly improved Investigator Global Assessment (IGA) rating to clear or almost clear. The cream has a suitable safety profile, with application site pain and dryness as the most common adverse events.
RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE IN COMPARISON TO EXISTING AGENTS
Tretinoin-BPO had similar IGA success compared to other topical retinoid and retinoid-BPO treatments for acne vulgaris. Compared to individual tretinoin and benzoyl peroxide therapy, the combination product streamlines application, which will improve medication adherence; however, the cost of tretinoin-BPO cream may be prohibitive.
CONCLUSIONS
Tretinoin 0.1%-benzoyl peroxide 3% cream is safe and effective for the treatment of moderate-to-severe acne. Long-term trial data on efficacy and tolerability are not yet available.

The effect of tomato and lycopene on clinical characteristics and molecular markers of UV-induced skin deterioration: A systematic review and meta-analysis of intervention trials.
Lycopene as a natural antioxidant that have been studied for ultraviolet radiation (UVR) photo protection and is one of the most effective carotenoids to scavenge reactive oxygen species (ROS). This review aims to summarize the protective effect of tomato and lycopene on skin photo damage and skin photoaging in healthy subjects by reviewing the existing population intervention experiments. A total of five electronic databases including PubMed, Scopus, EBSCO, Web of Science and Cochrane Library were searched from inceptions to January 2021 without any restriction. Out of 19336 publications identified, 21 fulfilled the inclusion criteria and were meta-analysis. Overall, interventions supplementing tomato and lycopene were associated with significant reductions in Δa*, MMP-1, ICAM-1 and skin pigmentation; while tomato and lycopene supplementation were associated with significant increase in MED, skin thickness and skin density. Based on the results of this systematic review and meta-analysis, supplementation with tomato and lycopene could reduce skin erythema formation and improve the appearance and pigmentation of the skin, thereby preventing light-induced skin photodamage and skin photoaging. Lycopene-rich products could be used as endogenous sun protection and may be a potential nutraceutical for sun protection.

Meta-Analysis
PURPOSE
The main purpose of this systematic review was to evaluate the association between the stroke (risk of stroke and the mortality due to stroke) and vitamin A, its organic compounds and its provitamins.
METHOD
Major databases including PubMed, Scopus, and Web of Science were searched. Studies with human samples were included for risk assessment. The association was assessed using odds ratio (()) and a random-effect model. statistic, variance () and prediction interval were used for heterogeneity assessment. The funnel plot was used for publication bias.
RESULTS
Twenty-one studies including 5789 stroke patients were retrieved. Twenty studies had sufficient information for quantitative analyses. The pooled effect showed an inverse association between vitamin A and its organic compound with the risk of stroke (() = -0.46 95%CI (-0.81;-0.12)) and with the risk of mortality due to stroke (() = -0.39 95%CI (-0.74;-0.04)). However, according to subgroup analyses, the association was dependent on the compound in a way that retinol and beta-carotene were the most effective compounds. The effects of several confounding factors and the threshold levels for vitamin A and its organic compound on the effectiveness were discussed.
CONCLUSION
Insufficiency of retinol and beta-carotene significantly increased the risk of stroke; however, due to heterogeneity between studies more studies are needed for evaluating clinical significance of this outcome.

Meta-Analysis
BACKGROUND
There is little evidence in scientific literature assessing the safety and efficacy of dual-lumen balloon catheters (DLBCs) and their performance compared to single-lumen catheters (SLCs).
METHODS
In this PROSPERO-registered, PRISMA-compliant systematic review, we identified all MEDLINE and EMBASE single-arm (DLBCs) and double-arm (DLBCs vs SLCs) cohorts where DLBCs were used for the treatment of cerebral arteriovenous malformations (AVMs) or dural arteriovenous fistulas (dAVFs). Immediate angiographic outcome, vascular complications, technical failures, reflux episodes and entrapment were the primary outcomes. A meta-analysis of the double-arm studies summarized the primary outcomes of total procedural time and immediate angiographic outcome.
RESULTS
The authors identified 18 studies encompassing 209 treated lesions with reported outcomes. Complete occlusion was achieved in 108/132 treated dAVFs (81.8%, 95% CI: [74-87.8%]) and in 45/77 treated AVMs (58.4%, [46.7-69.4%]). The proportion of completely occluded dAVFs was statistically significantly higher than that of AVMs, < .001. There were eight reported vascular complications (3.8%, [1.8-7.7%]), five technical failures (2.4%, [0.9-5.8%]), 14 reflux events (6.7%, [3.9-11.2%]), two entrapment events (1%, [0.2-3.8%]) and 0 deaths (mortality rate 0%, [0-2.3%]). In a meta-analysis for the treatment of dAVFs, the total procedural time was significantly less for DLBCs compared to SLCs (64.9 vs 125.7 min, < .0001). The odds of complete immediate occlusion were significantly higher with DLBCs compared to SLCs (odds ratio (OR) 4.6, [1.5-14.3], = .008).
CONCLUSION
Dual-lumen balloon catheters are safe and effective for the embolization of cerebral AVMs and dAVFs and can achieve faster and potentially superior results compared to SLCs.
