The potential role of miRNAs as biomarkers of myocarditis is promising, and miRNAs are expected to be utilized in various clinical fields in the future. |
∙ Nonpharmaceutical interventions (NPIs) have decreased the incidence of various infectious diseases, including coronavirus disease 2019 (COVID-19). ∙ During the 2-year COVID-19 pandemic, NPIs changed patients’ daily lives, and the impact on mental health was notable. ∙ The effects of NPIs were evaluated in detail, considering both infections and mental health. |
· Evidence shows that patients with type 1 diabetes have been severely affected by coronavirus disease 2019 (COVID-19) in various ways. · Although there is no reliable evidence that COVID-19 worsens or induces diabetes, it can impair β-cell insulin secretion and glucose control by inducing inflammation and cytokine production. · A study is needed of the short- and long-term relationship between diabetes and COVID-19 in the Korean pediatric population. |
Question: How many children and adolescents have experienced nonfatal injuries in the previous year? Finding: Among Korean children and adolescents, 8.1% experienced at least one injury per year. We found no significant change in the incidence of injuries over the previous 12 years. Meaning: The incidence of injuries is higher than this estimation; therefore, more attention and effort are needed to prevent injuries among children and adolescents. |
Question: Is fetal nuchal cord a risk factor for autism spectrum disorder (ASD)? Finding: Five articles (1 cohort, 4 case-control; total 3,088 children) were included in the present meta-analysis. Fetal nuchal cord was not a risk factor for ASD (odds ratio, 1.11; 95% confidence interval, 0.66–1.57). There was homogeneity among studies that reported a risk of ASD (I2=0.0). Meaning: Fetal nuchal cord is not a risk factor for ASD. |
∙ Recent epidemiologic changes of Japanese encephalitis (JE) in Korea are area (rural to urban or suburban) and age shift (children to adult). ∙ Although the main factors contributing to recent epidemiologic changes of JE are not well identified, maintaining high vaccination rates of JE appear to be important in preventing of JE in all age groups. ∙ Continuous surveillance for epidemiology and seroprevalence should be carried out. |
∙ Pediatric dyslipidemia is associated with several health problems besides cardiovascular diseases. ∙ There is a direct association between pediatric dyslipidemia and low serum vitamin D levels, asthma, and mental health problems regardless of body mass index. ∙ More large-scale nationally representative studies are needed to establish the appropriate cutoff points for the definition of dyslipidemia that is a prerequisite for further epidemiological studies in the Korean pediatric population. |
