Byung Ok Kwak, Byung Wook Eun
Clin Exp Pediatr. 2023;66(5):182-189.   Published online April 18, 2023
Most immunocompromised children and adolescents are not at increased risk of developing severe coronavirus disease 2019 (COVID-19). COVID-19 outcomes for low- or medium-risk immunocompromised children are favorable, while more serious illness reportedly occurs in high-risk immunocompromised children by underlying disease, its treatments, and other factors. Therefore, the early detection and timely management of severe COVID-19 and treatment of underlying disease are important. Hospitalization and COVID-19 vaccination should be carefully considered.

Not breastfeeding and risk of autism spectrum disorders among children: a meta-analysis   (13 times)
Ensiyeh Jenabi, Saeid Bashirian, Amir Mohammad Salehi, Salman Khazaei
Clin Exp Pediatr. 2023;66(1):28-31.   Published online July 19, 2022
This study aimed to determine whether there is an association between not breastfeeding (versus breastfeeding) and the risk of autism spectrum disorders (ASD) among children. We found that the risk of ASD associated with not breastfeeding had an odds ratio of 1.81 (95% confidence interval, 1.35–2.27; I2=0 %). These findings suggest the importance of breastfeeding in decreasing the risk of ASD among children.
