RESUMEN
Objectives@#Regression, while not a core symptom of autism spectrum disorder (ASD), has been suggested to be a distinct subtype by previous studies. Therefore, this study aimed to explore the prevalence and clinical differences between those with and without regression in children with ASD. @*Methods@#This study includes data from toddlers and young children aged 2–7 years acquired from other projects at Seoul National University Bundang Hospital. The presence and characteristics of regression were explored using question items #11–28 from the Autism Diagnostic Interview-Revised. Chi-square and independent t-tests were used to compare various clinical measurements such as autistic symptoms, adaptative behavior, intelligence, and perinatal factors. @*Results@#Data from 1438 young children (1020 with ASD) were analyzed. The overall prevalence rate of regression, which was mainly related to language-related skills, was 10.2% in the ASD group, with an onset age of 24 months. Regarding clinical characteristics, patients with ASD and regression experienced ASD symptoms, especially restricted and repetitive interests and behaviors, with greater severity than those without regression. Furthermore, there were significant associations between regression and hypertension/placenta previa. @*Conclusion@#In-depth surveillance and proactive interventions targeted at young children with ASD and regression should focus on autistic symptoms and other areas of functioning.
RESUMEN
Objectives@#The purpose of the study was to investigate the factors affecting unmet dental care needs among elderly living alone. @*Methods@#The study subjects were 19,019 elderly living by themselves, who participated in the Korea Community Health Survey 2018 (KCHS, 2018). The data were analyzed using frequency analysis, Rao-Scott chi-square test, t-test, and binary logistic regression analysis, using the SAS 9.4 software. @*Results@#Results from the multiple logistic regression analysis revealed a higher odds ratio (OR) for unmet dental care needs among those with a monthly household income below KRW 1,000,000 (OR=1.64, 95% confidence interval, 95%CI=1.39-1.92), compared to those with an income of above KRW 2,000,000. With regards to stress levels, unmet dental care needs were more prevalent among participants in the “stress moderate” (OR=1.19, 95% CI=1.06-1.33) and “stress” groups (OR=1.68 95% CI=1.48-1.92), compared to the “no stress” group. Furthermore, the OR for unmet dental care needs was significantly higher among participants in the “depression” group (OR=1.84, 95% CI=1.61-2.11) than the “no depression” group. @*Conclusions@#Higher unmet dental care needs were found among participants in the low monthly household income, stress, and depression groups. Further study is needed to analyze the association between factors and needs related to unmet dental care.
RESUMEN
Purpose@#In this prospective study, we evaluated the association between the serum levels of antioxidants uric acid (UA), albumin, and total bilirubin and the risk of cancer in a Korean population. @*Materials and Methods@#A total of 15882 subjects were followed up for cancer development and cancer-related death. During the follow-up period, 1619 cancer diagnoses and 617 cancer-related deaths were recorded. Cox proportional regression was performed to calculate the hazard ratio (HR) per standard deviation (SD) increment and 95% confidence interval (CI). The model was adjusted for covariates such as the age, sex, smoking, alcohol consumption, physical activity, education level, body mass index, and family history. Sensitivity analyses using the study subjects with physiological serum levels of each indicator were also performed. @*Results@#UA levels were positively correlated with cancer risk (HR per SD increment 1.04; 95% CI, 1.01–1.09), and albumin levels were inversely associated with the overall cancer risk (HR, 0.92; 95% CI, 0.88–0.96) and cancer-related death (HR, 0.86; 95% CI, 0.80–0.93). Total bilirubin levels were negatively correlated with the risk of cancer-related death (HR, 0.91; 95% CI, 0.83–0.99). By cancer type, UA was positively associated with prostate cancer, total bilirubin was positively associated with liver cancer, and albumin was inversely associated with lung cancer. @*Conclusion@#The findings of this study support the role of antioxidants in carcinogenesis. Future large-cohort studies are needed to confirm the predictive value of albumin, UA, and total bilirubin levels in each type of cancer.
