BACKGROUND/OBJECTIVES: Most child and adolescent food literacy measurement tools focus on nutrition and food safety. However, the importance of aspects related to the food system such as food distribution and food waste and their effects on environmental sustainability is growing. We therefore developed and validated a two-dimensional tool for children (8–12 years old) and adolescents (13–18 years old) that can comprehensively measure food literacy. The association of food literacy with diet quality and self-reported health was assessed. SUBJECTS/METHODS: First, we developed a food literacy conceptual framework that contains food system and literacy dimensions through a literature review, focus group interviews, and expert review. After a face validity study, we conducted the main survey (n = 200) to validate the questionnaire. Construct validity and reliability were assessed using exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and Cronbach's alpha. RESULTS: As a result of the Delphi study, content validity was confirmed for the remaining 30 items after two items were excluded (content validity ratio = 0.86). Eleven items were excluded from the EFA results, while the CFA results indicated appropriate fit indices for the proposed model (comparative fit index = 0.904, root mean square error of approximation = 0.068). The final food literacy questionnaire consisted of 19 questions and comprised 5 factors: production, distribution, selection, preparation and cooking, and intake. Food literacy was positively associated with diet quality, as assessed by the Nutrition Quotient score, in both children and adolescents and with self-reported health in adolescents. CONCLUSIONS Based on this integrated conceptual framework, a two-dimensional 19-item food literacy measurement tool was developed and verified for practical use to improve the diet quality and food-related environmental sustainability awareness of children and adolescents.

Mucinous adenocarcinoma arising from a chronic anorectal fistula is a rare condition. It is often confused with a hemorrhoid or perineal abscess, which consequently delays accurate diagnosis. Here, we report the case of a 58-year-old man with blood-tinged stool who reported a rectal mass, which was diagnosed as mucinous adenocarcinoma arising from an anal fistula. After initial computed tomography-guided needle aspiration biopsy had failed to provide an accurate diagnosis, transrectal punch biopsy was performed to obtained adequate tissue sample for confirmative histological diagnosis. The patient was successfully treated with neoadjuvant concurrent chemoradiotherapy followed by surgical intervention.

Since chronic diseases have emerged as a major cause of death worldwide, people has been exposed to large amounts of information on healthy eating practices that are important aspects of its prevention and management. Food literacy, the functional, interactive, and critical ability to manage dietary information with the aim of improving health, is of global interest. In South Korea (hereafter Korea), there is currently a lack of food literacy research, despite its pertinence for the development of public health policies that are tailored to recipients' ability to understand and address health and nutrition issues. In this study, the research trend and policy implications of food literacy are derived through reviewing preceding studies related to food literacy in Korea and elsewhere. Existing literature on food literacy in Korea placed much emphasis on the functional ability of food literacy. Future research on the operational definitions of interactive and critical food literacy and their health effects in Korea is necessary. In addition, there is a lack of research on the development and validation of measurement tools that evaluate integrative concepts of food literacy. To accurately examine the relationships among food literacy, diet, and health, standardized measurement tools that can comprehensively evaluate food literacy frameworks for various Korean sub-population groups should be developed. Based on such future studies, an investigation of health promotion programs or policies on reducing the cognitive burden of food literacy would contribute to improving heathy eating practices in Korea.

Objective: We aimed to compare cerebral beta-amyloid protein (Aβ) positivity rate and amyloid accumulation pattern on amyloid positron emission tomography (PET) between mild cognitive impairment (MCI) subtypes, i.e. amnestic mild cognitive impairment (aMCI) and non-amnestic mild cognitive impairment (naMCI). Methods: The study participants were 34 naMCI patients and age-, sex- and education-matched 68 aMCI patients (1:2 ratio) who visited the Dementia and Age-Associated Cognitive Decline Clinic of the Seoul National University Hospital. All participants received comprehensive clinical and neuropsychological assessments and [18F] florbetaben PET. Results: Aβ positivity rate of naMCI group (26.5%) was significantly lower than that of aMCI group (64.7%). Among Aβ positive individuals, there was no difference in Aβ accumulation pattern between naMCI and aMCI. Conclusion The findings suggest that MCI subtypes based on impaired cognitive domains have a differential association with brain Aβ deposition, a core pathology of AD. Amnestic subtype of MCI are more closely associated with cerebral Aβ deposition compared to nonamnestic subtype. In contrast, the pattern of amyloid deposition does not appear to have any difference between the subtypes.

BACKGROUND/OBJECTIVES: Dietary factors are important contributors to cardiometabolic and cancer mortality. We examined the secular trends of nine dietary factors (fruits, vegetables, whole grains, nuts and seeds, milk, red meat, processed meat, sugar-sweetened beverages, and calcium) and the associated burdens of cardiometabolic and cancer mortality in Korea using representative cross-sectional survey data from 1998 to 2016. SUBJECTS/METHODS: Using dietary data from Korean adults aged ≥ 25 years in the Korea National Health and Nutrition Examination Survey (KNHANES), we characterized secular trends in intake levels. We performed comparative risk assessment to estimate the population attributable fraction and the number of cardiometabolic and cancer deaths attributable to each dietary factor. RESULTS: A total of 231,148 cardiometabolic and cancer deaths were attributable to nine dietary risk factors in Korea from 1998 to 2016. Suboptimal intakes of fruits and whole grains were the leading contributors. Although the intakes of fruits, vegetables, and whole grains moderately improved over time, the intake levels in 2016 (192.1 g/d, 225.6 g/d, and 10.9 g/d, respectively) remained far below the optimal levels. Deaths attributable to the low intakes of nuts and seeds (4.5 g/d), calcium (440.5 mg/d), and milk (37.1 g/d) and the high intakes of red meat (54.7 g/d), processed meat (4.7 g/d), and sugar-sweetened beverages (33.0 g/d) increased since 1998. Compared with older age groups (≥ 45 years), more unfavorable changes in dietary patterns were observed in the younger population aged 25–44 years, including more sharply increased intakes of processed meat. CONCLUSIONS We observed improvement in the intakes of fruits, vegetables, and whole grains and unfavorable changes in the intakes of processed meat and sugar-sweetened beverages over the past few decades. Our data suggest that to reduce the chronic disease burden in Korea, more effective nutritional policies and interventions are needed to target these dietary risk factors.

Purpose: We aimed to investigate changes in visiting patterns after the lifting of mask mandates in a single pediatric emergency medical center in Seoul, Korea. Methods: This retrospective study was based on the data of patients’ (≤ 18 years) visits to the emergency department (ED) of the center from January 1, 2022 through June 30, 2023. Clinical characteristics, Korean Triage and Acuity Scale (KTAS) level, ED outcomes, and length of stay were compared between before (March 20-June 30, 2022) and after (March 20-June 30, 2023) the lifting of mask mandates. The comparisons were iterated in the patients with infectious disease. Results: During the study period, a total of 18,654 children visited the ED. After the lifting of mask mandates, ED visits increased from 7,146 to 11,508 (61.0%; 95% confidence interval, 59.5-62.6; P < 0.001). The increase was more prominent in the age of 2-5 years (82.9%), infectious diseases (175.3%), KTAS level 3 (127.7%), and length of stay shorter than 3 hours (78.8%-92.6%). The number of patients per hour increased by 151.2% for 5 patients or more and over 3,000% for 10 or more. Median length of stay decreased (2.3 hours [interquartile range, 1.2-4.1] to 1.9 hours [1.1-3.5]; P < 0.001). The patients with infectious disease (n = 7,139) showed similar patterns of increase in the age of 2-5 years, KTAS level 3, and length of stay shorter than 3 hours, with an additional increase in the age of 6-18 years. Conclusion After the lifting of mask mandates, pediatric visits increased by 61%, with the highest increase in children with mild infectious diseases on weekends and at night, and the proportion of more than 10 visits per hour significantly increased. We need urgent and realistic support measures from health authorities.

Purpose: This study was performed to analyze clinical features and use of renal replacement therapy (RRT) for children who visit the pediatric emergency department with benign acute childhood myositis (BACM) or rhabdomyolysis. Methods: We retrospectively reviewed medical records of 289 children who visited the emergency department with BACM or rhabdomyolysis from January 2013 through December 2022. Clinical features, laboratory and microbiological findings, and outcomes were compared between children with the two diagnoses. Subsequently, multivariable logistic regressions were performed to identify factors associated with applying RRT. Results: Of the 289 children, a total of 212 were analyzed, including 93 with BACM and 119 with rhabdomyolysis. Influenza (70 of the 145 children [48.3%]) was the most common cause, followed by exercise (36 of 212 [17.0%]). Compared with the children with BACM, those with rhabdomyolysis showed significantly higher frequencies of being boys and hematuria, and higher concentrations of hemoglobin, creatinine, creatine kinase, and myoglobin. Continuous venovenous hemofiltration, a modality of RRT, was applied to 8 children (6.7%) with rhabdomyolysis, of whom 1 died. Creatine kinase was independently associated with the application of RRT (adjusted odds ratio, 1.06; 95% confidence interval, 1.00-1.12; P = 0.036). Conclusion Rhabdomyolysis in children who require RRT may be associated with a higher concentration of creatine kinase.
