Handgrip Strength Correlates with Insulin Resistance and the Metabolic Syndrome in Children and Adolescents: Analysis of the Korean National Health and Nutrition Examination Survey 2014-2016

Woon Jung Hae , Ah Lee Young , Yong Lee Seong , Ho Shin Choong , Won Yang Sei , Hyun Kim Jae

Introduction: Reduced muscle strength is associated with increased cardiometabolic morbidity and mortality. Handgrip strength (HGS) is an indicator of muscle strength and has been correlated with total muscle strength in children and adolescents. We aimed to evaluate the association between HGS and parameters of the metabolic syndrome and insulin resistance in children and adolescents.Methods: A total of 2,242 children a...

Increasing Trend of Fasting Plasma Glucose Levels and Impaired Fasting Glucose in Non-Diabetic Korean Youth and Young Adults: A Nationally Representative Population-Based Study

Lee Jieun , Ah Lee Young , Hyun Kim Jae , Yong Lee Seong , Ho Shin Choong , Won Yang Sei

Objectives: Diabetes in children and young adults is increasing worldwide. However, the study of change in fasting glucose among general pediatric and young adult population was lacking. The aim of this study was to investigate the secular trend of fasting plasma glucose (FPG) levels in non-diabetic Korean youth and young adults and to evaluate the change in the proportion of impaired fasting glucose (IFG).Methods: Study subjects were Korean youth aged 1...

Predominant DICER1 Mutations in Pediatric Follicular Thyroid Carcinomas

Ah Lee Young , Im Sun-Wha , Cheon Jung Kyeong , Jae Chung Eun , Ho Shin Choong , Kim Jong-II , Park Young Joo

Background: Pediatric thyroid cancer has characteristics that are distinct from adulthood thyroid cancer. Due to its very low prevalence, little is known about the genetic characteristics of pediatric follicular thyroid cancer (FTC).Methods: We investigated genetic alterations in tumor tissues from 15 patients aged < 20 years (median: 14.3 years; range: 2.4-19.0 years) using multifaceted approaches. Whole-exome seque...

Changes in Adrenal Androgens and Steroidogenic Enzyme Activities in Children Aged 2, 4, and 6 Years: Steroid Hormone Profiling From the Prospective Cohort Study

Hyun Kim Jae , Ah Lee Young , Ho Shin Choong , Yang Sei Won , Song Junghan , Lim Youn-Hee , Kim Bung-Nyun , Inhyang Kim Johanna , Hong Yun-Chul

Introduction: Adrenarche refers to the increase in adrenal androgen synthesis. However, process of adrenal androgen production in early childhood remains to be elucidated. The aim of this study was to evaluate changes in adrenal androgen levels and steroidogenic enzyme activities associated with adrenarche using a prospective cohort.Methods: A total of 229 children (124 boys, 52.4%), who had participated in the Envir...

The Relationship Between Perfluoroalkyl Compounds Concentrations at Ages 2, 4, and 6 Years and Thyroid Function in Early Childhood: A Prospective Cohort Study

Young Kim Hwa , Kim Kyoung-Nam , Ah Lee Young , Lim Youn-Hee , Inhyang Kim Johanna , Kim Bung-Nyun , Oh Se-Young , Hong Yun-Chul , Ho Shin Choong

Backgrounds: Perfluoroalkyl compounds (PFCs) have been suggested as potential thyroid disrupting chemicals. However, previous studies about the associations between PFCs and childhood thyroid function are scarce, and inconclusive. We evaluated the PFC exposure in Korean preschool children, and investigated the temporal relationship with thyroid hormone concentration.Methods: From a prospective the Environment and Develop...

How Can the Occurrence of Delayed Elevation of Thyroid Stimulating Hormone in Preterm Infants Born Between 35 and 36 Weeks Gestation be Predicted?

Jung Heo You , Ah Lee Young , Jeong Lee Yun , Hee Lim Youn , Rim Chung Hye , Han Shin Seung , Ho Shin Choong , Won Yang Sei

Objective: We evaluated frequency and risk factors of delayed TSH elevation (dTSH) and investigated follow-up outcomes in the dTSH group with venous TSH (v-TSH) levels of 6–20 mU/L according to whether late preterm infants born at gestational age (GA) 35–36 weeks had risk factors.Methods: The medical records of 810 neonates (414 boys) born at Seoul National University Hospital who had a normal neonatal screenin...
