Background: Vitamin E supplementation is widely used in clinical practice for the prevention and treatment of different medical conditions. Evidence from basic science studies suggests that vitamin E may reduce immune allergic responses. However, only a few clinical studies of the effect of vitamin E on allergic conditions have been performed in patients with atopic dermatitis and asthma, and none have been performed in patients with allergic rhinitis.
Objective: To determine the effect of high-dose vitamin E supplementation in combination with the usual ("real-life") treatment on the symptoms of seasonal allergic rhinitis during the pollen season.
Methods: In a double-blind, placebo-controlled, randomized study, 112 patients with documented hay fever received either vitamin E (800 mg/d) or placebo in addition to their regular antiallergic treatment during the pollen season. Patients recorded their daily nasal and eye symptoms and their daily need for other medications to control allergic symptoms.
Results: Although no effect was observed on ocular symptoms, nasal symptom scores were lower in patients who received vitamin E supplementation during the hay fever season. However, there was no reduction in the percentage of days with serious symptoms or in the percentage of days that medications were used to control allergic symptoms during the pollen season.
Conclusions: Vitamin E supplementation may be a valuable addition to the treatment of patients with seasonal allergic rhinitis. However, further clinical and basic science studies are needed to determine its real value.

Correct treatment of chronic osteomyelitis depends on proper identification of the bone-infecting microorganism, but it is difficult identify the specific etiology in previously treated patients and in those with implants. Small colony variants auxotrophyc for menadione had been related with false-negative results in culture of patient with chronic osteomyelitis, but menadione supplementation can increase bone culture performance. The purpose was to evaluate the effect of menadione supplementation on isolates in bone cultures, in a cohort of patients with osteomyelitis, Medellín- Colombia.

Pharmaceutical supplementation and dietary fortification are the most common approaches to reducing vitamin deficits. To improve the health and nutritional value of crops, agronomic biofortification necessitates the direct application of nutrients. Producers using micronutrient fertilizers to increase the fortification of crops are essential to the success of biofortification.

Background: This study aims to investigate the association between vitamin D levels and the risk of severe acute exacerbations of chronic obstructive pulmonary disease (AECOPD).
Methods: We conducted a prospective observational study with 636 COPD patients admitted for exacerbations between January 2021 and December 2022. Patients were categorized based on serum 25-hydroxyvitamin D levels: severe deficiency (<10 ng/mL), deficiency (10-20 ng/mL), insufficiency (20-30 ng/mL), or sufficiency (>30 ng/mL).

Background Vitamin B12 deficiency, or cobalamin deficiency, is common among populations with low consumption of animal-based products, mainly in India, due to religious and socioeconomic factors, which significantly increase the deficiency rate. The condition has been characterized by a wide range of clinical and hematological symptoms, mainly affecting the blood and nervous system. This study aims to assess the clinical and hematological characteristics of patients with vitamin B12 deficiency and assess the therapeutic response to supplementation with vitamin B12.
