Moderate-to-vigorous physical activity modulates the association between serum 25-hydroxyvitamin D and bone stiffness in European children and adolescents.

It remains unclear how serum 25-hydroxyvitamin D (25(OH)D) concentrations relate to childhood bone health. We hypothesized that 25(OH)D was inversely associated with bone turnover biomarkers and positively associated with bone stiffness. Cross-sectional analyses were performed using data from participants (2-15-year-old, 51% boys) from the Identification and Prevention of Dietary- and Lifestyle-induced Health Effects in Children and Infants Study (IDEFICS)/I.

[Seroprevalence and infection by human parvovirus B19 in pregnant women from Córdoba, Argentina, 2021-2022].

Introduction: parvovirus B19 (B19V) infection during pregnancy can be transmitted to the fetus and cause serious complications such as fetal hydrops and stillbirth. The preexistence of specific IgG prevents vertical transmission. Seroprevalence in fertile age is variable (50-70%) and depends on the region/viral circulation, in addition to factors such as maternal age and frequent exposure to children.

Association of ability to rank sweet and fat taste intensities with sweet and fat food propensity ratios of children, adolescents and adults: the I.Family study.

Purpose: It is assumed that sensory taste perception shapes food choices and impacts dietary intake. However, this has rarely been studied in free living subjects of different age-groups with standardised methods. The present study investigated the association of the ability to rank sweet and fat taste intensities with consumption frequency of sweet and fatty foods in children, adolescents and adults from eight European countries.

Stakeholder Perspectives on Randomized Clinical Trials for Children With Poor-Prognosis Cancers.

Importance: In poor-prognosis children's cancers, new therapies may carry fresh hope for patients and parents. However, there is an absolute requirement for any new therapy to be properly evaluated to fulfill scientific, regulatory, and reimbursement requirements. Randomized clinical trials (RCTs) are considered the gold standard, but no consensus exists on how and when they should be deployed to best meet the needs of all stakeholders.

Age- and sex-specific reference percentile curves for accelerometry-measured physical activity in healthy European children and adolescents.

Unlabelled: Physical activity measured by accelerometry (PA-accelerometry) is used as an indicator of physical capacity in chronic diseases. Currently, only fragmented age ranges of reference percentile curves are available for European children and adolescents. This study aimed to provide age- and sex-specific percentiles for physical activity measured by hip-worn accelerometry derived throughout the full age range of European children and adolescents.
