Free radical-mediated oxidative stress has been implicated in the genesis and exacerbation of degenerative diseases. In view of the role of oxidative processes in hyperthyroidism, in this study, we investigated the antioxidant status of erythrocytes in experimental hyperthyroidism and the effect of vitamin E supplementation on defense systems. Our findings of significantly increased T4 and T3 and undetectable TSH values in thyroxine administered rats confirmed the establishment of hyperthyroidism. Superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and glutathione (GSH) values were found to be significantly increased in hyperthyroid rats in comparison to the control group. Vitamin E supplementation to hyperthyroid rats induced a significant decrease in GSH-Px activity and a significant increase in GSH level. These findings show that hyperthyroidism increases the components of the antioxidant system in the erythrocytes. Furthermore, vitamin E supplementation reduces the burden of oxidative stress in hyperthyroidism.

An 11-year-old male Bengal tiger () was referred for a 2-week history of ambulatory tetraparesis, generalized ataxia, and hypermetric gait, associated with mild right head tilt and spontaneous proprioceptive deficit on the right forelimb. Neuroanatomical localization was C1-C5 myelopathy; cerebellum-vestibular system involvement was also considered. Hematology and serum biochemistry were unremarkable, although serum vitamin A (0.

Pre- and perioperative management of malnutrition is crucial for the success of hip and knee arthroplasties. Various studies indicate that malnutrition, particularly when associated with vitamin D deficiency, significantly increases the risk of postoperative complications such as periprosthetic fractures and infections, prolonged hospital stays, and higher mortality rates. Adequate preoperative nutritional intake, including vitamin D supplementation, can improve arthroplasty outcomes.

Background: Randomised trials conducted from 2006 to 2021 indicated that vitamin D supplementation (VDS) was able to prevent severe COVID-19 and acute respiratory infections (ARI). However, larger randomised trials published in 2022 did not confirm the health benefits of VDS in COVID-19 patients.
Objective: To examine through a systematic review with meta-analysis the characteristics of randomised trials on VDS to COVID-19 patients and admission to intensive care unit (ICU), and of randomised trials on VDS for the prevention of ARI.
