The relationship between nutrition and frailty: Effects of protein intake, nutritional supplementation, vitamin D and exercise on muscle metabolism in the elderly. A systematic review.

Background: Frailty is a geriatric syndrome that predicts the onset of disability, morbidity and mortality in elderly people; it is a state of pre-disability and is reversible. The aim of this review is to assess how nutrition influences both the risk of developing frailty and its treatment.

Data Sources: We searched two databases, PubMed and Web of Science.

Serum albumin and health in older people: Review and meta analysis.

Albumin is the most abundant plasmatic protein. It is only produced by the liver and the full extent of its metabolic functions is not known in detail. One of the main roles assigned to albumin is as an indicator of malnutrition.

[Genetic profiles of longevity and healthy cognitive aging in nonagenarians from the Basque Country].

Introduction: Currently there are notable differences in the aging of individuals in modern populations. While some of them enjoy a long healthy aging, others develop neurodegenerative diseases, such as Alzheimer's disease (AD). Environmental factors are critical, but genetics could explain the differences observed.
