RESUMEN

BACKGROUND: Granuloma annulare has been linked to diabetes, dyslipidemia, thyroid disease, collagen vascular disease, malignancies, infectious hepatitis, and systemic infections. However, these associations have not been systematically investigated when categorized by its clinical variants. OBJECTIVE: To evaluate disease associations of localized and generalized granuloma annulare. METHODS: In total, 407 granuloma annulare patients from 1989 to 2019 were retrospectively reviewed, categorized by clinical variant (localized or generalized), age (pediatric or adult), and diagnostic method (clinical or histologic). Descriptive statistical analyses and multivariate logistic regression analysis were performed. Fisher's exact tests were conducted to produce unbiased probability values. RESULTS: Overall, 75.2% of the study sample was female, 47.2% had dyslipidemia, 24.8% were diabetic, and 24.6% had thyroid disease. Dyslipidemia (OR 2.15, CI 1.95-2.35, P < .001), diabetes (OR 1.16, CI 1.01-1.31, P = .041), and histologic diagnosis (OR 2.08, CI 1.21-3.52, P = .007) were associated with increased risk of GGA compared to LGA. When stratified by adult versus pediatric cases, dyslipidemia and diagnostic method remained significant, but diabetes did not. CONCLUSIONS: Evaluating granuloma annulare by its clinical variants may help to determine disease associations with each variant.

RESUMEN

PURPOSE: Eyelid basal cell carcinoma (BCC) is the most common eyelid malignancy. Metabolic reprogramming is critical in tumorigenesis, but the metabolic feature of eyelid BCC remains elusive. In this study, we aim to reveal the metabolic profile in eyelid BCC using targeted metabolomics. Eyelid samples were collected from patients who had removal of BCC and from control patients who underwent blepharoplasty. Multivariate analysis of metabolomics data distinguished the two groups, indicating that eyelid BCC has significantly different metabolome than the healthy tissue. We found 16 increased and 11 decreased metabolites in the BCC tissues. These metabolites were highly enriched in the metabolism of nicotinamide adenine dinucleotide (NAD), glutathione metabolism, polyamine metabolism, and the metabolism of glycine, serine, threonine, arginine and proline. amino acid metabolism. Metabolites from NAD metabolism (Nicotinamide; Nicotinamide riboside; N1-Methylnicotinamide) had the highest sensitivity, specificity, and prediction accuracy in a prediction model for eyelid BCC. In conclusion, eyelid BCC has a signature change of cell metabolome. Metabolites in NAD metabolic pathways could potentially be biomarkers or therapeutic targets for eyelid BCC.

RESUMEN

Type 2 diabetes mellitus is a major risk factor for cardiovascular disease and mortality. Uncontrolled type 2 diabetes mellitus results in a systemic milieu of increased circulating glucose and fatty acids. The development of insulin resistance in cardiac tissue decreases cellular glucose import and enhances mitochondrial fatty acid uptake. While triacylglycerol and cytotoxic lipid species begin to accumulate in the cardiomyocyte, the energy substrate utilization ratio of free fatty acids to glucose changes to almost entirely free fatty acids. Accumulating evidence suggests a role of miRNA in mediating this metabolic transition. Energy substrate metabolism, apoptosis, and the production and response to excess reactive oxygen species are regulated by miRNA expression. The current momentum for understanding the dynamics of miRNA expression is limited by a lack of understanding of how miRNA expression is controlled. While miRNAs are important regulators in both normal and pathological states, an additional layer of complexity is added when regulation of miRNA regulators is considered. miRNA expression is known to be regulated through a number of mechanisms, which include, but are not limited to, epigenetics, exosomal transport, processing, and posttranscriptional sequestration. The purpose of this review is to outline how mitochondrial processes are regulated by miRNAs in the diabetic heart. Furthermore, we will highlight the regulatory mechanisms, such as epigenetics, exosomal transport, miRNA processing, and posttranslational sequestration, that participate as regulators of miRNA expression. Additionally, current and future treatment strategies targeting dysfunctional mitochondrial processes in the diseased myocardium, as well as emerging miRNA-based therapies, will be summarized.

RESUMEN

INTRODUCTION: Previous studies have shown patient education material (PEM) in ophthalmology has been written at levels exceeding appropriate reading levels. However, information for readability in the field of oculoplastics remains limited. The aim of this study was to evaluate the readability of patient educational brochures from the American Society of Ophthalmic Plastic & Reconstructive Surgery (ASOPRS). METHODS: Patient educational brochures from ASOPRS were analyzed for readability. The body of text from all 18 ASOPRS patient brochures was analyzed by ten validated tests for English readability assessment: Flesch Reading Ease Test (FRE), Flesch-Kincaid Grade Level (FKGL), Simple Measure of Gobbledygook (SMOG), Coleman-Liau Index (CLI), Gunning Fog Index (GFI), New Dale-Chall Readability (NDC), FORCAST, Fry Graph Readability (FG), Raygor Readability Estimate (RRE), and New Fog Count (NFC). RESULTS: The mean (± SD) readability scores from the 18 ASOPRS patient brochures were 48 (4.3), 11.0 (0.8), 13.0 (0.7), 11.7 (0.8), 13.6 (0.9), 11.3 (0.8), 11.1 (0.5), 12.1 (1.5), 12.2 (1.0), and 10.6 (1.3) for FRE, FKGL, SMOG, CLI, GFI, NDC, FORCAST, FG, RRE, and NFC, respectively. All ten of the mean readability scores were above the recommended reading levels. CONCLUSIONS: These findings show that the average patient may have difficulty understanding educational information provided by ASOPRS patient brochures, thereby hindering their ability to make informed decisions on their healthcare. Revision with readability as a primary goal, with input from patients and caregivers, may be necessary to improve health literacy among patients who seek oculoplastic care.
