RESUMO
BACKGROUND: Older people are at risk of malnutrition, especially when they suffer from cognitive impairment. Guidelines that orient nursing care in this regard need to be updated. The aim of this review is to address the best available evidence on interventions that can benefit nutritional nursing care for institutionalized older adults with dementia. METHODS: Integrative review using the Dimensions and Eureka search engines, and the PubMed, Embase, Scielo, CINAHL, and ScienceDirect databases. We searched from the year 2015 through to 2021. We employed the MMAT guidelines for mixed, qualitative, and quantitative studies, and the PRISMA, CASP, and JBI guidelines to value the reviews. RESULTS: A total of 55 studies met the inclusion criteria. The best available evidence to support nutritional nursing care for institutionalized older adults with dementia highlights several aspects related to the assessment and caring interventions that are focused on people with dementia, their caregivers, and their context. CONCLUSIONS: Both the assessment and nutritional care interventions for older people with dementia should consider the patient-caregiver dyad as the subject of care and understand the context as a fundamental part of it. The analysis of the context should look further than the immediate environment.

Legumes are a good source of vegetal protein that improves diets worldwide. Cowpea has been used as fortification agents in some traditional corn foods in developing countries such as Colombia. The work aimed to evaluate the physicochemical properties of extruded mixtures of corn and cowpea flours to assess the use of these mixes as vegetable protein ingredients. Corn flour was mixed with 15, 30, and 50% of cowpea flour and extruded for this proposal. After extrusion, mixtures were ground to produce a powder. Techno-functional properties of powders as water content, hygroscopicity, water absorption, fat absorption, water solubility index, swelling index, bulk density, Hausner ratio, Carr index, and porosity were evaluated in the mixtures, extrudates, and obtained powders to assess the effect of the addition of cowpea on these properties. Results showed that processing powder obtained by extrusion and drying could be used as a powder to regenerate with water as a source of protein. Moreover, storing processing samples in sections (pellet format) is convenient to avoid wetting since this format is less hygroscopic and the same mass occupies less storage volume than powders.
RESUMO
In Latin America, popular tradition in some places have been attributed properties to borojó fruit, making it a potential source for the design and development of a functional product, but there is little scientific literature reference biological activity of this fruit. The aim of this study was to evaluate color changes, polyphenol content and antioxidant capacity of borojo (Borojoa patinoi Cuatrecasas) pulp beverage without chemical preservatives, it was stored at 4° C, 17° C and 37° C for 17 days. Coordinate a* was adjusted to zero order kinetics and the total polyphenol content (TP) and the antioxidant capacity (CA) had adjustments to first-order kinetics, suggesting a linear correlation between the degradation rates. The results showed that beverage storage at 4°C allowed a better retention of color changes, polyphenols and antioxidant compounds in nature, compared with the other storage temperatures.
En Latinoamérica, la tradición popular en algunas poblaciones le han atribuído al fruto del borojó propiedades, que lo hacen fuente potencial para el diseño y desarrollo de productos de carácter funcional; sin embargo es poca la literatura científica aún, que referencia alguna actividad biológica de este fruto. El objetivo de este trabajo fue evaluar los cambios de color, el contenido de polifenoles y la capacidad antioxidante de una bebida de pulpa de borojó (Borojoa patinoi Cuatrecasas.) sin conservantes químicos, ésta fue almacenada a 4º C, 17º C, y 37º C durante 17 días. En color la coordenada a* se ajustó a una cinética de orden cero; el contenido de polifenoles totales (PT) y la capacidad antioxidante (CA) presentaron ajustes a una cinética de primer orden, sugiriendo una correlación lineal entre las velocidades de degradación. Los resultados obtenidos indicaron que el almacenamiento de la bebida a 4° C permitió una mejor retención en los cambios de color, polifenoles y compuestos de carácter antioxidante, en comparación con las demás temperaturas de almacenamiento.
