Atypical Cogan's Syndrome with Choroidal Effusion: A Case Report.

Cogan's syndrome is a rare form of autoimmune vasculitis that manifests with ocular and audiovestibular symptoms. The clinical presentations of Cogan's syndrome can be classified as typical and atypical, and the auditory symptoms are classically similar to those seen in cases of Meniere's syndrome. Without treatment, Cogan's syndrome could become severe, resulting in sensorineural hearing loss in over 50% of patients.

An Investigation on Korean Adolescents' Dietary Consumption: Focused on Sociodemographic Characteristics, Physical Health, and Mental Health.

The promotion of healthful dietary intake in adolescents is an important public health concern, as obesity is on the rise among adolescents. The current study aimed to determine the association between sociodemographic characteristics and dietary intake (breakfast, vegetables, milk, fruits, fast food, carbohydrate beverages, and caffeine beverages) and to examine the influences of physical and mental health on dietary intake. A nationally representative sample of 187,622 adolescents who attended middle and high schools and participated in the Korean Youth Risk Behavior Survey (2015, 2017, and 2019) was used.

This paper aims to identify service quality dimensions of street food that have an impact on utilitarian and hedonic values and to determine the effect of utilitarian and hedonic values on repurchase intention. It also examines the moderating effect of risk perception toward street food safety on the relationship between service quality and perceived value. An Internet survey was performed in Korea with 285 respondents.

An Integrative Review of Hygiene Practice Studies in the Food Service Sector.

Abstract: This article reviews the recent literature on studies relevant to hygiene practices of food service workers. A total of 32 articles were chosen for evaluation from a systematic search of the published literature from 2014 to 2019. For the assessment of hygiene practices, hand washing as a measurement item and observation as a method were most frequently used.

Correlation Analysis between Ocular Surface Parameters with Subjective Symptom Severity in Dry Eye Disease.

Purpose: To evaluate the clinical symptoms of patients with dry eyes, based on the ocular surface disease index (OSDI) and analyze the relationship between OSDI and various ocular surface parameters.

Methods: This was a retrospective study that included 45 eyes of 45 dry eye patients who visited the Seoul Nune Eye Hospital from August 2017 to December 2017. The patients were assessed by non-invasive keratography for the first break-up time, lipid layer thickness (LLT), tear osmolarity, tear matrix metalloproteinase-9 immunoassay as well as with the conventional Schirmer I test and fluorescein break-up time.

Quercetin Protects Obesity-Induced Hypothalamic Inflammation by Reducing Microglia-Mediated Inflammatory Responses via HO-1 Induction.

Obesity-induced hypothalamic inflammation is characterized by activation of microglia, which are resident macrophages of the central nervous system, and is implicated in the derangement of energy homeostasis, metabolic complications, and neurodegenerative diseases. Quercetin, a naturally occurring flavonoid, is known to protect against oxidative stress and inflammation-related metabolic complications. Here, we demonstrate that quercetin reduces obesity-induced hypothalamic inflammation by inhibiting microglia-mediated inflammatory responses, and the beneficial action of quercetin is associated with heme oxygenase (HO-1) induction.
