Benign Paroxysmal Positional Vertigo (BPPV) is a common vestibular disorder characterized by vertigo episodes due to head position changes. Emerging research suggests a link between Vitamin D deficiency and BPPV, attributed to Vitamin D's role in calcium metabolism essential for inner ear function. This study investigates the relationship between Vitamin D levels and the incidence, severity, and recurrence of BPPV. This year-long prospective cohort study was conducted at a tertiary care center, enrolling 100 patients diagnosed with BPPV. Vitamin D levels were measured and classified as deficient, insufficient, or sufficient. Patients identified with Vitamin D deficiency (< 20 ng/mL) received supplementation at a dose of 2000 IU daily for six months. Participants were followed monthly for one year to monitor the incidence and severity of BPPV episodes, assessed using the Vertigo Symptom Scale, and recurrence rates. Statistical analysis included Kaplan-Meier curves, log-rank tests, and Cox proportional hazards models to evaluate the Vitamin D-BPPV relationship. The study revealed that patients with Vitamin D deficiency (< 20 ng/mL) had a 71% incidence of BPPV, compared to 20% in those with sufficient levels. The average severity score was higher in the deficient group (7.5) versus the sufficient group (3.5). Vitamin D supplementation correlated with reduced BPPV incidence and severity over time. The findings indicate a significant link between Vitamin D deficiency and increased BPPV incidence and severity, highlighting Vitamin D's role in vestibular health. These results suggest that Vitamin D supplementation could be integral to BPPV management. Further research, including controlled studies, is needed to understand the mechanisms behind these associations and their clinical implications.

Peroxisome proliferator-activated receptor-γ (PPARγ) is a critical regulator of adipogenesis and bone metabolism, playing complex roles in osteoporosis. This study investigates the effects of taurine and homocysteine on PPARγ, focusing on their roles in osteoclastogenesis and bone health. In-silico analyses, including molecular docking and molecular dynamic simulations, revealed that both taurine and homocysteine bind competitively to the PPARγ ligand-binding domain, exhibiting distinctive antagonistic modes, including destabilization of PPARγ's key helices H3, H4/5, H11, and H12.

Although parenteral iron is widely used to treat iron deficiency anemia (IDA), some side effects have been inadequately explored. Hypophosphatemia is becoming a well-documented, yet poorly understood, side effect of parenteral iron infusion, oftentimes causing serious and/or prolonged complications. In this article, we discuss the case of a 33-year-old female with IDA who suffered debilitating physical and mental symptoms of significant recurrent hypophosphatemia following a single standard dose of parenteral iron administration.

Ataxia with Vitamin E Deficiency (AVED) is a rare autosomal recessive genetic disorder, that caused by pathogenic variants in the TTPA gene, which encodes the alpha-tocopherol transfer protein. This study investigates eight patients from three consanguineous Iranian families, using exome sequencing (ES) and Sanger sequencing to identify novel pathogenic variants in the TTPA gene. Two variants were identified: c.

Food fortification is an effective strategy to combat vitamin A deficiency. Gari, a cassava-based West African food product, is an interesting product to fortify with vitamin A, but the low stability of vitamin A poses a challenge. We showed that toasted wheat bran can stabilise vitamin A as retinyl palmitate (RP) during storage of RP-fortified gari to a limited extent.
