Middle-aged and elderly perimenopausal women are prone to developing BPPV without definite cause. Objectives: This study aimed to investigate the correlation between bone mineral density (BMD), 25-(OH) vitamin D, and serum calcium levels in patients with benign paroxysmal positional vertigo (BPPV) in middle-aged and elderly women. A total of 103 women with two or more recurrent BPPV episodes (group A) and 80 age-matched healthy controls (group B) were recruited. All subjects had BMD and serum 25-(OH) D levels measurements taken, and the results were compared. BMD was reduced in group A, and the proportion of osteoporosis was higher than in group B ( = .039). The BMD T-score and 25-(OH) vitamin D level were lower in group A than in group B ( = .004 and < .0001, respectively). In group A, the BMD T-score was lower ( = .017) and serum 25-(OH) vitamin D level was higher ( < .0001) in premenopausal women than in menopausal women. Our study found that middle-aged and elderly women with recurrent BPPV, especially postmenopausal women, may present decreased BMD and serum vitamin D levels.

Background: The association between 25-hydroxy-vitamin D [25(OH)D] levels and glycemic control in pediatric patients with type 1 diabetes mellitus (T1DM) is unclear. In this study, we aimed to investigate the association between 25(OH)D levels and glycemic control in Saudi pediatric patients' with T1DM in a region that is sunny year-round.
Materials And Methods: A retrospective study was conducted in the Pediatric Department of King Saud Hospital in Unaizah, Saudi Arabia.

There is little research on anemia and vitamin D deficiency in HIV-exposed uninfected (HEU) children. This study was aimed to describe and compare the prevalence of anemia and vitamin D inadequacy in HEU children and HIV-unexposed uninfected (HUU) children, and to examine the associations of HIV exposure with anemia and vitamin D inadequacy. This was a hospital-based descriptive cross-sectional study nested within the Prevention of Mother-to-Child Transmission (PMTCT) of HIV program in Hunan Province during July and September 2022.

Vitamin D receptor (VDR) plays a critical role in regulating multiple biological processes, including bone metabolism and cell differentiation, by mediating transcriptional activation in response to ligand binding. We have constructed an environmentally fluorescent probe 2 for VDR to facilitate real-time observation of its ligand-dependent conformational changes in living cells. This probe 2 was synthesized by introducing a dansyl fluorophore via an ethynyl group at the C11 position of 1α,25(OH)2D3.

Objective: There is a dearth of published data on the vitamin D status of the Ugandan population; the objective of the study was to determine the prevalence of vitamin D deficiency among pregnant women in Uganda and its associations with maternal characteristics and adverse foetal-maternal outcomes.
Study Design And Setting: We conducted a cross-sectional study on pregnant women admitted to a tertiary referral hospital in Kampala, Uganda for delivery during the study period from July to December 2023.
Participants: The study was conducted on 351 pregnant women aged ≥18 years who consented to participate in the study, who had a single intrauterine pregnancy and a gestational age greater than 26 weeks, and who delivered at St.

Establishing specific reference intervals (RIs) of serum 25-hydroxyvitamin D3 [25(OH)D] for children is essential for improving the accuracy of diagnosis and prognosis monitoring of diseases such as rickets and growth retardation. The study including 6,627 healthy children was conducted to establish specific RIs of 25(OH)D for children in Nanning area of China. The results showed that there were statistically significant differences among age, season, and gender of serum 25(OH)D levels, and the age-specific RIs of serum 25(OH)D were 20.
