RESUMEN
This letter acknowledges Finsterer and colleagues' insightful comments on pesticide use in fruits and vegetables and impact on eye health. Pesticides can harm eyes through various exposures. Adverse effects occur due to direct entry into ocular tissues, with absorption through eye components. While the potential of organic diets to reduce pesticide exposure is acknowledged, the original paper's cited studies lack clarity on whether organic diet interventions were used. Future systematic reviews comparing organic and nonorganic diets could provide further insights.
RESUMEN
Pseudo-pregnancy is an uncommon psychiatric presentation, often having a complex interplay of psycho-social factors making it difficult to manage. It is common to present in the reproductive age range, rarely in postmenopausal women. We are reporting a rare presentation of a 48-year post-menopausal widowed HIV-positive female with no live issues having two years of secondary amenorrhea complaining to have documented weight gain and experience of perceiving fetal movements for the past 5 months. However, she persistently insisted on antenatal care despite repeated reports of ultra-sonographic pelvis imaging and gynecological examination pointed toward menopausal changes and the absence of any live issue. This case report emphasizes the clinical presentation and management strategies for patients with pseudocyesis, a peculiar and rare psychiatric manifestation.
RESUMEN
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.
