Adolescents experience significant growth in social cognition, including perspective taking and identity formation. Due to the salience of race and ethnicity in the United States, adolescents' ethnic-racial identity (ERI) may have important implications for their sociocognitive development. The present study tested the association between ERI in early adolescence and subsequent longitudinal growth in perspective taking. Participants included 560 adolescents assessed annually over 4 years, beginning in sixth and seventh grade. Adolescents were from a small, rural community in the southeast United States and were from diverse ethnic-racial backgrounds (primarily Latine, Black/African American, and multiracial). Using linear growth curve modeling, we examined whether initial ERI predicted intercepts and slopes of longitudinal growth in perspective taking across adolescence. Results showed that the development of perspective taking differed based on initial ERI. Perspective taking increased significantly for youth with low and average levels of ERI but remained high and stable for youth at high levels of ERI. This study offers important evidence that Latine, Black, and multiracial youth who explore and find more clarity in their sense of ERI earlier in adolescence also show higher initial levels of perspective taking, which remains high across adolescence. Over time, most youth grow in perspective taking and eventually reach similar levels, but youth high in ERI reach these higher levels earlier than their peers, who had less sense of clarity about their ERI early in adolescence. This is one of the first known studies to directly test the association between ERI and perspective taking, utilizing a diverse, longitudinal sample of adolescents.

Background: Osteocalcin is a metabolic active hormone, which correlates positively with bone formation and inversely with body mass index and waist circumference in adults.
Objectives: To investigate whether osteocalcin in infancy and early childhood were related to childhood growth or body composition.
Methods: A Swedish longitudinal birth cohort with blood samples from 551 children from birth until 5 years of age.

3D photogrammetry is a cost-effective, non-invasive imaging modality that does not require the use of ionizing radiation or sedation. Therefore, it is specifically valuable in pediatrics and is used to support the diagnosis and longitudinal study of craniofacial developmental pathologies such as craniosynostosis - the premature fusion of one or more cranial sutures resulting in local cranial growth restrictions and cranial malformations. Analysis of 3D photogrammetry requires the identification of craniofacial landmarks to segment the head surface and compute metrics to quantify anomalies.

Background: Pediatric kidney transplant recipients experience creeping creatinine, which is a slow increase in serum creatinine over time. Distinguishing between normal growth-related changes and possible allograft dysfunction becomes challenging when interpreting the increase in serum creatinine. We hypothesized that changes in BSA-indexed measured glomerular filtration rate (mGFR) or creatinine-estimated GFR (eGFR) might not be a true reflection of the renal function post-transplant and that for longitudinal follow-up a stable absolute mGFR is better.

Introduction: Maternal undernutrition and inflammation in utero may significantly impact the neurodevelopmental potential of offspring. However, few studies have investigated the effects of pregnancy interventions on long-term child growth and development. This study will examine the effects of prenatal nutrition and infection management interventions on long-term growth and neurodevelopmental outcomes of offspring.

Hypertension and bicuspid aortic valve (BAV) are key clinical factors that may affect local biomechanical properties of ascending thoracic aortic aneurysms (ATAAs). This study sought to investigate regional differences in biaxial mechanical properties of the ATAAs for the hypertensive patients with BAV. Fresh ATAA samples were harvested from 16 hypertensive patients (age, 66 ± 9 years) undergoing elective aortic surgery.
