Conclusion: Deficiencies or imbalances in specific vitamins and minerals, especially vitamin B, vitamin D, Fe, Se, and Zn are involved in the pathogenesis of AGA and may represent modifiable risk factors for the treatment and prevention of this condition.
PubMed 39440586 ↗Conclusion: This guideline should enable addressing suboptimal and deficient status of a bundle of MNs in at-risk diseases. In particular, it offers practical advice on MN provision and monitoring during nutritional support.
PubMed 35365361 ↗Conclusion: Based on the high-level data provided in this review, the use of specific nutritional interventions may improve the outcome of certain wound types. Further investigation is warranted to draw definitive conclusions.
PubMed 34181622 ↗Conclusion: Exposure to arsenic, lead, cadmium, and copper is associated with an increased risk of cardiovascular disease and coronary heart disease. Mercury is not associated with cardiovascular risk. These findings reinforce the importance of environmental toxic metals in cardiovascular risk, beyond the roles of conventional behavioural risk factors.
