Purpose: The objective of this study was to analyze vitamin D status and PTH concentrations in 6- to 8-year-old girls with central precocious puberty.
Methods: A cross-sectional clinical and blood testing study (calcium, phosphorus, 25(OH)D and PTH) was carried out in 78 girls with central precocious puberty (CPP group), aged 6.1-7.9 years. A control group was recruited (137 prepubertal girls, aged 6.1-8.2 years). The criteria of the US Endocrine Society were used for the definition of hypovitaminosis D.
Results: There were no significant differences in vitamin D status between both groups. There were no significant differences in 25(OH)D concentrations between CPP (25.4 ± 8.6 ng/mL) and control groups (28.2 ± 7.4 ng/mL). In contrast, PHT concentrations in CPP group (44.8 ± 16.3 pg/mL) were higher (p < 0.05) with respect to control group (31.0 ± 11.9 ng/mL). In CPP group, there was a positive correlation (p < 0.05) between PTH concentrations and growth rate, bone age, and basal estradiol, basal FSH, basal LH and LH peak concentrations.
Conclusion: Vitamin D status in 6- to 8-year-old girls with CPP is similar to that in prepubertal girls. PTH concentrations were significantly higher in girls with CPP, and this could be considered as a physiological characteristic of puberty and, in this case, of pubertal precocity.

Calcium is the most abundant mineral in the human body. About 99% of calcium is deposited in the bones in the form of hydroxyapatite and only 1% is located in the intracellular and extracellular fluid. Ionized calcium, which makes up about 50% of the total amount of circulating calcium, is biologically active; the remaining percentage is bound to plasma proteins (40%, of which albumin accounts for 90%, and globulins for 10%), or is in complex with anions (10%) such as citrate, lactate, bicarbonate, phosphate.

Introduction: vitamin A is a nutrient required for normal visual system function, growth, and development. Periodic vitamin A supplementation is a cost-effective strategy for preventing vitamin A deficiency in children. This study aimed to assess the coverage and associated factors of vitamin A supplementation among children aged 6-59 months in Gondar City, Northwest Ethiopia 2022.

Background: Vitamin D (VD) deficiency and insulin resistance (IR) increase the risk of non-alcoholic fatty liver disease (NAFLD), but few studies have explored the potential mechanisms by which IR mediates the association between VD and the pathogenesis of NAFLD at the genetic level using publicly available databases.
Methods: This is a cross-sectional study, and we utilized the National Health and Nutrition Examination Survey (NHANES) dataset, as well as data from GSE200765 obtained from the Gene Expression Omnibus (GEO) website. A total of 723 individuals who had completed liver ultrasound examination and the detection of VD levels were included in the final analysis.

Nitrous oxide (NO) has been increasingly used for recreational purposes due to its dissociative and euphoric properties. Exposure to NO results in the deactivation of in vivo vitamin B, leading to subsequent neurological sequelae due to vitamin B deficiency.7 Current management focuses on cessation of exposure and replacement therapy, yet patients may continue to suffer from permanent neurological damage.

Background: The high prevalence of malnutrition among those of older age and the lack of nutrition knowledge among the elderly and their caregivers underscore the need for a nutrition education intervention (NEI) for caregivers.
Materials And Methods: Patients enrolled in the "home care program" who were dependent, were >65 years of age, and had caregivers (n = 94) were included in the study. A nutritionist conducted initial NEI sessions for caregivers and subsequently monitored them monthly at home for 12 months.
