Unlabelled: A cross sectional study was made on 60 patients (9.9 +/- 1.8 yr-old) with congenital hypothyroidism (CH) (group A): 40 girls (23 prepubertal) and 20 boys (18 prepubertal). Control group (group B) was constituted of 28 healthy children (10.4 +/- 2.1 yr-old): 18 girls (8 prepubertal) and 10 boys (9 prepubertal).
Aims: To evaluate bone mineral density (BMD) and content (BMC) and to correlate them with chronological and bone age (BA), sex, sexual maturation, l-T4 dose, TSH, TT4, FT4, and CH etiology. BA, total body BMD, and BMC (DXA) were obtained of both groups. TSH, TT4, and FT4 were measured in patients only. BMD was lower in group A (0.795 +/- 0.075 g/cm(2) vs. 0.832 +/- 0.092; p = 0.04) and higher in pubertal than in prepubertal girls (p = 0.004). There was no significant difference between BMD and BMC related to sex and CH etiology. Our data demonstrated that BMD was significantly lower in children with CH, different from what has been published in the literature.

Unlabelled: Dietary acid load could be associated with bone mass, but there are limited and conflicting results. This secondary cross-sectional analysis evaluated these associations among 123 children/adolescents, mostly Hispanics. Dietary acid load seems to be associated with bone mass in boys, but these results should be confirmed through long-term studies.

Unlabelled: Low-sodium salt has a protective effect on BMD and also reduces the risk of osteopenia due to elevated blood glucose. This provides a direct and effective way to improve bone health in patients with hyperglycemia.
Objective: There is no consensus on the relationship between salt type and bone mineral density (BMD).
Calcium to magnesium ratio as a superior biomarker for nephrolithiasis detection in primary hyperparathyroidism.

Primary hyperparathyroidism (pHPT) is marked by mineral imbalances, often leading to nephrolithiasis and osteoporosis. While imaging remains the cornerstone for stone detection, there is growing interest in biochemical markers that could enhance diagnostic accuracy. This study investigates the calcium-to-magnesium (Ca/Mg) ratio as a novel biomarker for nephrolithiasis, comparing its utility to traditional 24-h urinary calcium excretion and exploring its broader clinical implications.

Due to the high cost of the available Pt electrocatalysts, the large-scale water electrolysis production of hydrogen has been hindered. Hydrogen generation via electrochemical water splitting is a renewable energy essential to a sustainable society, creating a distinct material interface that shows Pt-like properties with long-term stability crucial to hydrogen evolution reactions (HERs). Here, we synthesized the guanine-assisted facile synthesis of 1 wt % Pt/MoC/C having a layered type morphology via solid state calcined process followed by chemical reduction.

Probiotics benefit the health and production performance of chickens, but their impact on egg and eggshell quality, particularly in the later stage, remains unclear. Here, 1-day-old Tianfu green shell-laying hens were fed either non-probiotics feed (n = 180) or feed supplemented with 100 mg / kg probiotics (n = 180). 16S rDNA sequencing indicated that dietary probiotics decreased the distribution of uterine p_Firmicutes, g_Fusobacterium, and s_Fusobacterium_unclassified, while increased p_Proteobacteria, g_Ralstonia, and s_Ralstonia_unclassified.
