The aim of this study was to investigate the association between percent contribution of ultra-processed foods to total dietary energy intake and measurements of body composition obtained using high-validity methods. ⋯ The contribution of ultra-processed foods to total dietary energy intake of Brazilian adolescents was associated with body composition, especially with decreasing lean body mass.

This study aimed to evaluate knowledge, attitudes, and practices toward added sugar intake and the associations with nutrient intakes and weight status. ⋯ Our findings indicated that a large proportion of young women had limited knowledge on the health consequences of excessive added sugar intakes. The observed inverse relationships between added sugar and micronutrient intakes and the weight status highlight the urgent need for expanded efforts to improve added sugar-related knowledge and promote the reduction of added sugar intake among young women.

Weight loss has been validated as a prognostic predictor of nasopharyngeal carcinoma (NPC); however, no global unitary indicator and criteria exist for the definition of weight loss as a prognostic factor. The aim of this study was to determine the most effective indicator for weight loss, evaluate its effect on the prognosis of NPC, and further propose a cutoff value to identify patients in need of nutritional care. ⋯ PWL is a promising predictor for NPC, and cutoff values could be validated for nutritional risk grading in patients with NPC. These stratified criteria may help accelerate the extensive application of grading nutritional management in NPC therapy.

High-risk patients ≥65 y of age with coronavirus disease 2019 (COVID-19) tended to have lower serum prealbumin concentrations. The aim of this study was to investigate the association of prealbumin at baseline on COVID-19-related mortality in elderly patients (≥65 y of age). ⋯ Prealbumin is an independent risk factor of in-hospital mortality for elderly patients with COVID-19. Assessment of prealbumin may help identify high-risk individuals ≥65 y of age with COVID-19.

This paper reviews the published evidence on early-life intestinal microbiota development, as well as the different factors influencing its development before, at, and after birth. A literature search was done using PubMed, Cochrane and EMBASE databases. A growing body of evidence indicates that the intrauterine environment is not sterile as once presumed, but that maternal-fetal transmission of microbiota occurs during pregnancy. ⋯ A growing number of studies have reported on how the composition and development of the microbiota during early life will affect risk factors related to health up to and during adulthood. If exclusive breastfeeding is not possible, the composition of infant formula should be adapted to stimulate the development of a bifidobacterial-dominated gut microbiota typical of that observed in breastfed infants. The main components in breast milk that stimulate the growth of specific bifidobacteria are HMOs.
