Selenium deficiency in children and adolescents nourished by parenteral nutrition and/or selenium-deficient enteral formula

Increased oxidative stress in patients with severe disability: Association with nutrition

“…found that serum Zn was well correlated with glutathione reductase or superoxide dismutase activity, particularly in orally fed patients . Although we did not find any significant difference in oxidative stress between food and formula, physicians should pay attention to the fact that most semi‐digestive nutritious liquids lack Se . In the present study, carotenoid intake was inversely correlated with urinary 8‐OHdG.…”

“…26 Although we did not find any significant difference in oxidative stress between food and formula, physicians should pay attention to the fact that most semi-digestive nutritious liquids lack Se. 27 In the present study, carotenoid intake was inversely correlated with urinary 8-OHdG. Of interest is that plasma carotenoid concentration was inversely correlated with urinary 8-OHdG excretion in women previously treated for breast cancer.…”

Selenium supplementation in pediatric patients using parenteral nutrition: Is it time to do something?

“…These values are within the normal range described in several studies with the same population. 4,7,[19][20][21] Laboratory assessment of the clinical picture The other laboratory tests used in the research were those routinely used to accompany the patient in PN. Dosage and blood collection were performed by the Clinical Pathology Laboratory team of the Hospital de Clínicas.…”

Hair, Nails, and Skin: Differentiating Cutaneous Manifestations of Micronutrient Deficiency

“…This is particularly true for vegetarians living in selenium‐deficient areas . Deficiency may also occur in patients on long‐term hemodialysis; receiving long‐term PN; having chylous loss, phenylketonuria, or malabsorption disorders; and in individuals with HIV . Selenium deficiency leads to whitened nailbeds (Figure ), impaired immune function, and skeletal myopathy.…”
