Purpose: To determine absolute and relative ocular protrusion values for healthy Lithuanian children and adolescents and analyze the data according to the age, gender, weight, height, and outer orbital distance.
Methods: A total of 397 children and adolescents were included in this study. Measurements for the right and left eyes protrusions were done with Hertel exophthalmometer in healthy subjects aged from 5 to 18 years old. Height, weight, age and gender of subjects were recorded.
Results: The mean age for all children and adolescents was 11.5 ± 3.6 years. For all subjects, the mean (±SD) absolute ocular protrusion value of both eyes (OU) was 14.91 ± 1.68 mm. There was no significant difference in measurements between male and female subjects although female eye protrusion was higher. No individual had more than 2 mm of asymmetry between eyes. Mean exophthalmometric values for right eye were greater than the values of the left eye, and the mean relative protrusion for all participants was 0.2 mm. The mean distance between the lateral rims of the orbits was 98.7 ± 5.2 mm for all subjects. Proptosis measurements significantly correlated with the age, weight and height of children and adolescents and base measurements.
Conclusions: In the present study, we have established ocular proptosis values according to the age, gender, weight and height of healthy Lithuanian children and adolescents. The eye protrusion significantly correlated with the age, weight and height of subjects and the distance between the lateral rims of the orbits. The gender did not play significant role on the eye projection data. We believe that larger, well-design studies are necessary in future to assess the distribution of proptosis in healthy Lithuanian children and adolescents.

Nutrition and Mental Health Research Group (NUTRISAM), Universitat Rovira i Virgili, Tarragona, Spain.
Exposure to heavy metals has been associated with affecting children's neurodevelopment, particularly increasing the risk of developing attention-deficit hyperactivity disorder (ADHD). The current exploratory study aims to investigate potential associations between presence of 15 different heavy metals in urine and ADHD. A total of 190 urine samples of participants from clinical and non-clinical population (non-ADHD = 66; ADHD = 124) aged between 6 and 15 years from Barcelona and Tarragona (Spain) were analysed.

The aim of this systematic review was to summarize the dietary intake of children and adolescents living with HIV and its association with cardiovascular risk factors. PubMed/MEDLINE, Scopus, Web of Science, BIREME and LILACS were searched for original observational studies. The studies were extracted between June and August 2021, in addition to a manual search of references.

Background: Climate change has raised significant concerns about its impact on health, particularly for vulnerable populations such as children and adolescents. While extensive research has examined physical health effects, limited attention has been given to the influence of extreme heat on developmental and behavioral outcomes.
Objectives: This study investigates the association between extreme heat exposure and early puberty initiation (ages 9-10), using data from the Adolescent Brain Cognitive Development (ABCD) study.
