Microbial Phenolic Metabolites Are Associated with Improved Cognitive Health.

SCOPE: Diets rich in polyphenols has been associated with better cognitive performance. The aim of this study is to assess the relationship between microbial phenolic metabolites (MPM) in urine and cognition in the context of an older population at high cardiovascular risk. METHODS AND RESULTS: A cross-sectional analysis is conducted in 400 individuals of the PREDIMED-Plus study. Liquid chromatography coupled to mass spectrometry is used to identify urinary MPM. Mediterranean diet (MedDiet) adherence is estimated with a 17-item questionnaire and cognitive function is evaluated with a battery of neuropsychological tests. Multivariable-adjusted linear regression models are fitted to assess the relationship of urinary MPM with the MedDiet and cognitive tests. Protocatechuic acid and enterolactone glucuronide are associated with higher adherence to the MedDiet. Regarding cognitive function, protocatechuic acid, vanillic acid glucuronide, 3-hydroxybenzoic acid, enterodiol glucuronide, and enterolactone glucuronide are directly associated with a global composite score of all the cognitive tests. Furthermore, protocatechuic acid and enterolactone glucuronide are associated with higher scores in the Mini-Mental State Examination, whereas enterodiol glucuronide is associated with improved Clock Drawing Test scores. CONCLUSIONS: These results suggest that the MedDiet is linked to MPM associated with better cognitive performance in an older population.

Accidental implant screwdriver aspiration: A case series report with literature review and proposed action protocol.

This article presents the first reported case series of three cases of aspiration of a dental implant screwdriver, which was successfully removed by flexible bronchoscopy. The report highlights preventive measures that can be taken in the dental office and the clinical signs and symptoms of the presence of a dental implant screwdriver in the bronchial tree. The nine reports published to date on this phenomenon are reviewed and compared, and an action protocol for dental practitioners, anaesthetists and pulmonologists is proposed to address this emergency. Some early and late complications are also described.

Pumpkin seeds (Cucurbita maxima): a review of functional attributes and by-products / Semillas de calabaza (Cucurbita máxima): una revisión de sus propiedades funcionales y sub-productos

ABSTRACT The need to obtain nutritious foods from new sources and lower waste in industry has created a high interest in studying different parts of plants or foods that today are considered waste, but could be considered by-products with high nutritional value with potential use in human diets. Pumpkin seeds are commonly considered as waste but they have a high content of fatty and amino acids, which when used as a by-product or ingredient can add value to food products. The aim of this work was to perform a wide review of the nutritional and functional properties of Cucurbita maxima seeds and their potential medicinal influence.

RESUMEN La necesidad de obtener alimentos nutritivos de nuevas fuentes y menores desperdicios en la industria ha generado un gran interés en el estudio de diferentes partes de plantas o alimentos que hoy en día se consideran desechos, pero que podrían considerarse subproductos con alto valor nutricional y uso potencial en alimentación humana. Las semillas de calabaza se consideran comúnmente como desechos, pero tienen un alto e importante contenido de ácidos grasos y aminoácidos, que cuando se utilizan como subproducto o ingrediente pueden aportar un alto valor agregado a los productos alimenticios. El objetivo de este trabajo es realizar una amplia revisión de las propiedades nutricionales y funcionales de las semillas de Cucurbita maxima y su potencial influencia medicinal asociada a ellas.
