The impact of nutritional status on health‑related quality of life in hemodialysis patients

Malnutrition is frequent in hemodialysis (HD) patients. Nutritional deficiencies may negatively impact quality of life (QOL). This study examines the utility of the Malnutrition-Inflammation Score (MIS) in detecting nutritional risk (NR) and assesses the correlation between nutritional status and QOL in dialysis patients upon starting a nutritional intervention program (NIP). One hundred and twenty patients were included in this cross-sectional study. The MIS was used to detect NR and the Kidney Disease Quality of Life (KDQOL-SF) instrument version 1.2 was used to assess QOL. 62% of patients were found to be at NR (MIS > 5). Nutritional status was significantly correlated with all generic QOL sub-scales. On a multiple linear regression analysis, malnutrition showed the highest level of explanation in the Kidney Disease Summary Component which explained 28.9% of the variance; the Physical Component Summary which explained 33% of the variance; and the Mental Component Summary which explained 21.5% of the variance. Malnutrition was found to be the most significant predictor of impaired scores on the KDQOL-SF. The use of MIS to identify patients at NR and a nutritional assessment to detect malnutrition in its early stages are important given the effects a NIP can have on improving QOL in HD patients

Artichoke By-Products as Natural Source of Phenolic Food Ingredient

Nowadays, the transformation activity of the food industry results in the generation of a huge amount of daily discarded vegetables wastes. One of those undervalued by-products are produced during the post-harvesting and processing process of artichokes. In the present research, the potential of artichokes’ bracts and stalks have been evaluated as a natural source of phenolic compounds which could be used as bioactive food ingredients, among others. In this study, the bioactive composition of those wastes has been evaluated using recent advances in extraction and analytical technologies, concretely, pressurized liquid extraction (PLE) followed by high-performance liquid chromatography (HPLC) coupled to electrospray time-of flight mass spectrometry (ESI-TOF/MS) analysis. To achieve this goal, first, the extraction process was evaluated by a comparative study using GRAS (Generally Recognized As Safe) solvents (mixtures of ethanol and water) at different temperatures (40–200 ◦C). The second step was to deeply characterize the composition of individual polyphenols by HPLC-ESI-TOF/MS in order to establish a comparison among the different PLE conditions applied to extract the phenolic fraction. The analysis revealed a wide variety of phenolic-composition, mainly phenolic acids and flavonoids. The results also highlighted that high percentages of ethanol and medium-high temperatures pointed out to be useful PLE conditions for recovering this kind of phytochemicals, which could be used in different applications, such as functional food ingredients, cosmetics, or nutraceuticals

Sensitivity of C-band backscatter to surface roughness parameters measured at different scales

SAR (Synthetic Aperture Radar) sensors measure the backscatter (sigma(0)) of land covers and SAR images have a number of applications in agricultural soils (soil moisture, crop monitoring, etc.) but the surface roughness of these soils complicates their interpretation and determination of quantitative estimates of useful parameters. The aim of this study is to quantify the spatial variability of different roughness parameters and the sensitivity of. 0 to them measured at different scales. Ten Envisat/ASAR images acquired between September 2004 and January 2005 on an agricultural area with 10 control plots are analyzed. 132 roughness profiles of 5 m length were measured, and 21 different parameters were calculated. The results show considerable differences in the spatial variability of the parameters and differed depending on the type of parameter in the correlation analysis. This study can be useful to identify roughness parameters and scales that maximize their sensitivity to C-band backscatter

Jóvenes y sexo en la red: Reacción ante la exposición involuntaria a material sexual

En los últimos años, hemos sido testigos de tan gran expansión de la pornografía en la red que resulta imposible aislar toda esa pornografía a portales y páginas Web concretas. Esto lleva a que en ocasiones, las personas sean expuestas involuntariamente a contenidos sexuales explícitos en páginas que no deberían contener este tipo de materiales. Este hecho, que en adultos no parece especialmente problemático, podría resultar una experiencia realmente aversiva para adolescentes que todavía están en pleno desarrollo psicosexual. Por ello, se planteó esta investigación con el objetivo de conocer la frecuencia y la experiencia que supone para los adolescentes de nuestra comunidad la exposición involuntaria a material sexual en Internet. En este trabajo, se aplicó a una muestra de 141 estudiantes (48,2 % chicos; 51,8 % chicas) de entre 15 y 16 años un cuestionario diseñado ad hoc para la evaluación de todas las dimensiones implicadas en la exposición involuntaria. Los resultados evidencian una frecuencia de exposición involuntaria muy alta (86,5 % de la muestra expuesta involuntariamente), exposición a la que los jóvenes suelen reaccionar cerrando la ventana y eliminando el contenido. La vivencia de esta experiencia se define normalmente en términos negativos (asco, sorpresa, vergüenza, etc.) y lo que es más preocupante, la mayoría de los jóvenes expuestos experimentó posteriormente síntomas de embotamiento y evitación (77,3 %), síntomas sexuales (75,5 %) o de hiperactivación fisiológica (71,7 %).In recent years, we have been witness to a great expansion of pornography on the Net. As a result, it is not possible to isolate all this pornography to specific sites or web pages. For this reason, sometimes people are unwanted exposed to sexually detailed materials in pages that should not contain such materials. In adults, involuntary exposure seems to be harmless, whereas in children and adolescent, the exposure could be extremely upset. In this study, we focus on the frequency and the short-term / long-term effects of the involuntarily exposure in adolescents. For this purpose, 141 Spanish young people (48,2 % males and 51,8 % females), age ranged from 15 to 16 years, completed an Ad-Hoc questionnaire designed for the evaluation of the unwanted exposition experience. The results show a very high frequency of involuntary exposure (86.5 % of the sample unwanted exposed). Young people usually react to the involuntarily exposition closing the window and erasing the sexually materials. The majority of youth regard their personal unwanted exposures as distressful (disgusting, shameful, surprising, etc.). Finally, the majority of youth who had been exposed experienced apparent stress symptoms that they connected to the episode (77,3 % of the sample experienced avoidance; 75,5 sexual symptoms; 71,7 physiological arousal)

Olive OilWaste as a Source of Functional Food Ingredients: Assessing Polyphenolic Content and Antioxidant Activity in Olive Leaves

Around two million tons of olive oil are produced in Europe annually, with Portugal being among the top five European olive oil-producing countries. Olive oil production results in a substantial amount of waste in the form of olive leaves. These discarded olive leaves contain valuable phenolic compounds with antioxidant, anti-inflammatory, hypoglycaemic, neuroprotective, and antiproliferative properties. Due to their richness in polyphenols with health-promoting properties, olive leaves can be considered a potential functional food ingredient. Thus, sustainable practices for reusing olive leaf waste are in demand. In this study, the polyphenolic content in olive leaves from different Portuguese locations was determined using HPLC-UV-Vis after defining the best fit-forpurpose liquid extraction strategy. The differences in the in vitro antioxidant activity in these samples were determined by several methodologies based on radical scavenging (against 2,2′-azino-bis-3- ethylbenzthiazoline-6-sulphonic acid (ABTS), 2,2-diphenyl-2-picrylhydrazyl (DPPH), and peroxyl radical (ORAC)) and on reducing properties (cupric-reducing antioxidant capacity (CUPRAC), and Folin–Ciocalteu assay (FC)), to unveil the relationship between the profile and quantity of polyphenols with antioxidant mechanisms and their capacity. At last, the stability of extracted compounds upon lyophilization and exposition to surrogate biological fluids was assessed, envisioning the future incorporation of olive leaves extracted compounds in food products.Ministero dell’Università e della Ricerca (MIUR) through the Programma Operativo Nazionale Ricerca e Innovazione 2014–2020 (CCI 2014IT16M2OP005)European Social Fund for her PhD grant (DOT18FFNZ8)FCT for the institutional funding granted to LAQV-REQUIMTE (ref.

Pharmacist role in the nutrition area at the European level

Una vez licenciado, el farmacéutico puede optar por un elevado número de salidas profesionales, tanto en el sector público al servicio de los diferentes cuerpos y administraciones, como en el sector privado. Los perfiles profesionales más frecuentes del farmacéutico pueden englobarse en 4 modalidades: Oficina de Farmacia (Farmacia Comunitaria), Farmacia Hospitalaria, Distribución e Industria Farmacéutica o Análisis y Salud Pública. A nivel de oficina de farmacia, el farmacéutico, junto a la dispensación de medicamentos, ejerce un destacado papel como asesor y consejero de salud. Las estadísticas desvelan que una de cada cuatro personas que entran en una farmacia no adquiere medicamentos, sino que sólo pide un consejo sanitario, incluyendo asesoría sobre dietas, alimentación y nutrición. Además, la aparición en los últimos años de complementos alimenticios, de venta en farmacia, hace que el farmacéutico deba formarse y comportarse como profesional en lo que respecta a temas de nutrición. Otra salida profesional, como la inspección Farmacéutica, incluye la supervisión de agua y alimentos no animales, por lo que el farmacéutico debe tener un amplio conocimiento sobre la legislación, sanidad y análisis de alimentos. Por otro lado, la industria farmacéutica incluye una amplia variedad de salidas profesionales, incluyéndose dirección técnica, control de calidad y de fabricación, gestión comercial, documentación científica o análisis. La industria agroalimentaria ha experimentado importantes cambios en las últimas décadas, exigiendo profesionales en la materia, como dietistas o analistas bromatológicos, dentro de un equipo multidisciplinar. En este sentido, el farmacéutico, a través del nuevo grado en Farmacia, debe adquirir una base sólida en el campo de la nutrición y bromatología. Así, las competencias recogidas en la Orden CIN/2137/2008 ponen de manifiesto la importancia de la formación del futuro farmacéutico en el ámbito de la alimentación.Once graduated, the pharmacist can choose a high number of professional skills, both in public and private sectors. The most frequent professional skills of the pharmacist can be included in 4 different fields: Pharmacy Office (Communitary Pharmacy), Hospital Pharmacy, Distribution and Pharmaceutical Industry or Analysis and Public Health. At the pharmacy office level, the pharmacist, along with the medicines dispensation, exercises an out-standing role as health adviser. The statistics reveal that 25% of the pharmacy customers do not acquire medicines, but they only ask for a sanitary advice, including nutrition and dietetic consultations. Moreover, in the last years nutritive supplements have been included within the pharmaceutical sales. Thus, the pharmacist should be formed about nutritional topics. Another professional skill, like the pharmaceutical inspection, includes drinkable water and non-animal foodstuffs analyses. Then, the pharmacist should have a wide knowledge on legislation, health and food analysis. On the other hand, the pharmaceutical industry includes a wide variety of professional skills, including technical direction, quality control, commercial management, scientific documentation or analysis. Finally, the agro-alimentary industry has experienced important changes in the last decades, demanding professionals in the matter, like dietitians or food analysts. In this sense, the pharmacist, across the new degree in Pharmacy, must acquire a solid base in the nutrition and bromatology field. Therefore, the competences gathered in the Disposition CIN / 2137/2008 reveals the importance of the formation of the future pharmacist in the nutrition area

The new degree in pharmacy. Is it enough for the formative needs in the nutrition area?

La importancia de la alimentación en la consecución de la salud y en la prevención de la enfermedad y la necesidad de un buen control de la dieta para alcanzar resultados satisfactorios en la reducción del riesgo, tratamiento y control de muchas de las enfermedades crónicas, es un hecho documentado científicamente y de gran relevancia en la sociedad actual. La Orden CIN/2137/2008, de 3 de julio establece los requisitos para la verificación de los títulos universitarios oficiales que habiliten para el ejercicio de la profesión farmacéutica, abarcando diversas competencias que aluden directamente a la formación del farmacéutico en el campo de la nutrición. Entre ellas se incluyen 1) Prestar consejo terapéutico en farmacoterapia y dietoterapia, así como consejo nutricional y alimentario a los usuarios de los establecimientos en los que presten servicio. 2) Conocer la relación existente entre la alimentación y salud, y la importancia de la dieta en el tratamiento y prevención de las enfermedades. 3) Desarrollar análisis higiénico-sanitarios (bioquímico, bromatológico, microbiológicos, parasitológicos) relacionados con la salud en general y con los alimentos y medio ambiente en particular. 4) Conocer las técnicas analíticas relacionadas con el diagnóstico de laboratorio de tóxicos, alimentos y medioambiente. En este sentido, el nuevo Grado en Farmacia aprobado por el Consejo de Gobierno de la Universidad de Granada incluye la asignatura troncal “Nutrición y Bromatología” de 6 créditos. Sin embargo los créditos obligatorios aprobados por la ANECA para esta materia en 8 Universidades Españolas oscilan entre 7,5 para Sevilla y 12 créditos para Madrid con una media de 9,4 créditos. De esta forma ¿Es posible cubrir con los 6 créditos asignados a esta materia una formación mínima para que el farmacéutico pueda realizar adecuadamente las competencias que se le han asignado?The importance of nutrition on human health and on illness prevention, and the need for a good control of the diet to reach satisfactory results in the reduction of the risk, treatment and control of many of the chronic diseases, is a scientifically documented fact quite relevant in the current society.
