Copper and Copper/Zinc Ratio in a Series of Cystic Fibrosis Patients.

Cystic fibrosis (CF) patients require a stable and sufficient supply of micronutrients. Since copper is an essential micronutrient for human development, a cross-sectional study was carried out to investigate the serum copper levels, serum copper/zinc (Cu/Zn) ratios, and their relationship with nutritional indicators in a group of CF patients. Anthropometric, biochemical, and dietary measurements, an abdominal ultrasound, and respiratory and pancreatic tests were conducted.

Zinc Nutritional Status in Patients with Cystic Fibrosis.

Background: Zinc is an essential nutrient for all forms of life and its deficiency affects the normal growth and development of human beings.

Objective: The main aim was to investigate zinc nutritional status by serum zinc concentration (SZC) and dietary zinc intake and their association in cystic fibrosis (CF) patients.

Methods: A cross-sectional study was conducted in CF patients.

Bioelectrical impedance vector reference values for assessing body composition in a Spanish child and adolescent population.

Objectives: Reference values of the bioelectrical impedance vector for the Spanish child and adolescent population are needed for assessing body composition and hydration status in this population. The aim of this study is to provide reference values of the bioelectrical impedance vector in Spanish children and adolescents aged 4-18 years from Castilla y León.

Methods: This was a cross-sectional descriptive study conducted in 4401 Spanish healthy children and adolescents aged 4-18 years (2265 boys and 2136 girls).

Anorexia nervosa (AN) is the most prevalent of eating disorders in children and adolescents, and its treatment is long and complex, involving a multidisciplinary team. Nutritional rehabilitation and restoration of a healthy body weight is one of the central goals in the initial stages of inpatient treatment. However, current recommendations on initial energy requirements for these patients are inconsistent, with a clear lack of controlled studies, available scientific evidence and global consensus on the most effective and safe refeeding practices in hospitalized adolescents with anorexia nervosa (AN).

Ongoing population ageing is one of the factors influencing the increase in the prevalence of undernutrition, as elderly people are a vulnerable group due to their biological, psychological and social characteristics. Despite its high prevalence, undernutrition is underdiagnosed in the geriatric sphere. For this reason, the aim of this consensus document is to devise a protocol for geriatric nutritional assessment.

Bioimpedance vector analysis and conventional bioimpedance to assess body composition in older adults with dementia.

Objective: Although dementia and nutritional status have been shown to be strongly associated, differences in body composition (BC) among older people with dementia have not yet been firmly established. The aim of this study was to assess BC through conventional and vector bioimpedance analysis (BIA and BIVA, respectively) in a sample of institutionalized older men with and without dementia, in order to detect dementia-related BC changes.

Methods: Forty-one institutionalized men ages ≥ 65 y (23 without dementia [CG] and 18 with dementia [DG]) were measured with BIA and interpreted with BIVA and predictive equations.
