AI Article Synopsis
- The study aimed to establish reference values for bone health in young Brazilian athletes, focusing on bone mass content (BMC), bone mass density (BMD), and total body less head (TBLH) BMD using a sample of 702 athletes aged 8.5-18.5 years.
- Findings revealed that male athletes had significantly higher BMC and BMD than female athletes in the older age groups, indicating sex-based differences in bone health as athletes grow.
- The newly developed age-, sex-, and ethnic-specific reference values provide a valuable tool for assessing bone health over time, helping to monitor growth and track athletic development in young athletes.
Article Abstract
Reference values for bone mass in young athletes need to be used for screening purposes, and country/regional reference values should be used to improve precision of comparisons. The aim of the present study was to develop reference values for bone health variables in Brazilian young athletes. The bone mass content (BMC), bone mass density (BMD), and total body less head (TBLH) BMD using dual-energy X-ray absorptiometry were measured in 702 young athletes (327 men and 375 women) aged 8.5-18.5 years, divided into 5 groups, according to their age: group 1 (8.5-10.5 years), group 2 (10.6-12.5 years), group 3 (12.6-14.5 years), group 4 (14.6-16.5 years), and group 5 (16.6-18.5 years). Comparisons between the sexes and ages were performed and age-sex-smoothed reference values were constructed. Male athletes presented high BMC and BMD than female athletes in age groups 3, 4, and 5 (p < 0.005) and high TBLH BMD than female athletes in age groups 4 and 5 (p < 0.005). Reference values, including the percentiles are presented for the bone health variables of each sex and age group. The age-, sex-, and ethnic-specific reference data for bone variables presented in this study enabled more precise reference data for young Brazilian athletes. These data may assist in monitoring changes during an athletes' growth and different phases of athletic training.

Background: Effective treatment of late antibody-mediated rejection (late AMR) is still an unmet medical need. Clearing donor-specific antibody (DSA) and preventing its rebound is the ideal goal of treatment.
Methods: We have summarized the clinical data from seven patients with late or chronic active AMR after renal transplantation who received daratumumab (Dara)-based treatment first (Phase 1) and then tocilizumab (TCZ) therapy (Phase 2).

Background & Aims: In the general population, 24-hour urine potassium excretion is considered the reference standard for estimating potassium intake. However, its agreement with food records and spot urine collections in adults living with chronic kidney disease (CKD) is not well-established. Given the risk of hyperkalemia related to changes in renal potassium handling, understanding if this reference standard is appropriate for the CKD population is important.

An idea of using ion-exchanger salt containing optically active cations to prepare ion-selective membranes is proposed. Although the presence of an ion-exchanger in the composition of neutral ionophore based sensors is necessary, the choice of available salts for cation-selective sensors preparation, is usually limited to sodium or potassium compounds. In this work we propose application of an alternative salt, using a cation optically active both in absorption and emission mode as a mobile one.

Waste pile substrates from Fe mining may carry potentially toxic elements (PTE). Rehabilitation efforts must maintain soil vegetation cover effectively, avoiding the dispersion of particulate matter and reducing the risk to the environment and human health. Therefore, this study aims to evaluate the pseudo-total and extractable contents, perform chemical fractionation, and assess the bioaccessibility and risk of PTE in waste piles of Fe mining in the Eastern Amazon.
