  4. High-Dose Vitamin C (PDQ®): Complementary and alternative medicine - Health Professional Information [NCI] - General Information

    Vitamin C is an essential nutrient that has antioxidant functions, is a cofactor for several enzymes, and plays an important role in the synthesis of collagen.[1] A severe deficiency in vitamin C results in scurvy, which is associated with malaise, lethargy, easy bruising, and spontaneous bleeding.[2] One of the effects of scurvy is a change in collagen structure to a thinner consistency. Normal consistency is achieved with administration of vitamin C.In the mid-20th century, a study hypothesized that cancer may be related to changes in connective tissue, which may be a consequence of vitamin C deficiency.[3] A review of evidence published in 1974 suggested that high-dose ascorbic acid may increase host resistance and be a potential cancer therapy.[4]Vitamin C is synthesized from D-glucose or D-galactose by many plants and animals. However, humans lack the enzyme L-gulonolactone oxidase required for ascorbic acid synthesis and must obtain vitamin C through food or

  6. Family Caregivers in Cancer: Roles and Challenges (PDQ®): Supportive care - Health Professional Information [NCI] - Impacts of Caregiving on the Caregiver's Quality of Life

    Caregiver burden is commonly used to describe multiple dimensions of distress that result from an imbalance between care demands and the availability of resources to meet those demands. Although quality of life is a multidimensional construct, the most studied aspect of quality of life in caregivers is psychological distress.[1] Most family caregivers do not experience clinically significant levels of depression when providing care, but some studies report levels of depressive symptoms in caregivers that are similar to, or even higher than, those in patients with cancer.[2][Level of evidence: II]Physical ImpactThe physical aspects of caregiving have rarely been studied. Caregiving may be solely limited to physical care such as helping with toileting or eating but can also include lifting, positioning, transferring, massaging, and operating medical equipment. The physical demands of caregiving are closely related to medical variables such as the following:Disease stage.Level of
