Infant exposure of perfluorinated compounds: Levels in breast milk and commercial baby food
2010
In this study, an analytical method to determine six previous termperfluorinatednext term compounds (PFCs) based on alkaline digestion and solid phase extraction (SPE) followed by liquid chromatography-quadrupole-linear ion trap mass spectrometry (LC-QqLIT-MS) was validated for the analysis of human breast milk, milk previous terminfantnext term formulas and cereals baby food. The average recoveries of the different matrices were in general higher than 70% with a relative standard deviation (RSD) lower than 21% and method limits of detection (MLOD) ranging from 1.2 to 362 ng/L for the different compounds and matrices. The method was applied to investigate the occurrence of PFCs in 20 sample…

2019
Introducción: Analizar la composición corporal tanto mediante técnicas antropométricas y parámetros bioquímicos clásicos, como mediante técnicas modernas utilizando tomografía computarizada (TC), en pacientes oncológicos antes de iniciar el tratamiento con radioterapia.Metodología: Se analizaron de forma retrospectiva 22 pacientes con diversos tumores del aparato digestivo, que fueron sometidos al TC de planificación antes de iniciar el tratamiento con radioterapia, y que disponían de un corte axial en la tercera vértebra lumbar. Para analizar la composición corporal, se determinaron tanto parámetros antropométricos y bioquímicos clásicos, como la determinación de la masa muscular mediante …
Tomografía computarizada a nivel de C3 y dinamometría como técnicas de diagnóstico de sarcopenia en pacientes con cáncer de cabeza y cuello
2020
Introducción: Estudio piloto que determina el diagnóstico de sarcopenia mediante tomografía computarizada (TC) a nivel de la tercera vértebra cervical (C3) y dinamometría en pacientes con cáncer de cabeza y cuello. Comparación de la masa magra (MM) determinada mediante TC con técnicas clásicas de antropometría y dinamometría.Material y métodos: Se analizó la MM y el tejido adiposo mediante TC a nivel de C3 en 37 pacientes oncológicos mediante Unidades Hounsfield (UH). Posteriormente, se calculó el índice musculoesquelético (IME) y se determinó la fuerza prensora de mano para la determinación de sarcopenia. Por último, se comparó el IME mediante técnicas de valoración antropométrica clásica …
Dietary Glycaemic Index Labelling: A Global Perspective
2021
The glycaemic index (GI) is a food metric that ranks the acute impact of available (digestible) carbohydrates on blood glucose. At present, few countries regulate the inclusion of GI on food labels even though the information may assist consumers to manage blood glucose levels. Australia and New Zealand regulate GI claims as nutrition content claims and also recognize the GI Foundation’s certified Low GI trademark as an endorsement. The GI Foundation of South Africa endorses foods with low, medium and high GI symbols. In Asia, Singapore’s Healthier Choice Symbol has specific provisions for low GI claims. Low GI claims are also permitted on food labels in India. In China, there are no nation…
Cambios en el estado nutricional, composición corporal y sintomatología asociada en pacientes hospitalizados sometidos a trasplante de médula ósea: e…
2021
Introducción: Los pacientes sometidos a Trasplante de Células Madre Hematopoyéticas o trasplante de médula padecen varias complicaciones nutricionales. El objetivo del estudio fue realizar una descripción prospectiva en estos pacientes.Material y métodos: Se reclutaron 14 pacientes con una edad media de 48,0±9,8 años. Resultados: El 28,6% padecía sobrepeso, el 14,3% obesidad y el 57,1% tenía un peso normal, con una evoluciónentre -0,3±0,3 kg/m2 (normopeso) hasta -3,1±0,2 kg/m2 (obesidad). Se observó una pérdida de peso variable, de hasta 7,3±0,7% en pacientes con mayor Índice de Masa Corporal (IMC). La composición corporal también empeoró al alta, con una evolución de la circunferencia braq…
Association between Intake of Energy and Macronutrients and Memory Impairment Severity in US Older Adults, National Health and Nutrition Examination …
2020
Without a cure, dementia affects about 50 million people worldwide. Understanding the effects of dietary habits, a key lifestyle behavior, on memory impairment is critical to inform early behavioral modification to delay further memory loss and progression to dementia. We examined the associations of total energy intake and energy intake from macronutrients with memory impairment among older US adults using data from the nationally representative National Health and Nutrition Examination Survey study 2011&ndash
The discursive legitimation strategies of a nascent market
2017
Since the introduction of Gold&Green Foods Ltd’s Pulled Oats (Nyhtökaura) to the Finnish market in the spring 2016, the Finnish media has been increasingly reviewing different plant-based protein products. Gold&Green Ltd’s Pulled Oats has experienced extensive media coverage amongst other Finnish plant-based protein products which have been launched during 2016 such as VersoFood Ltd’s Härkis, Viipurilainen Kotileipomo’s Puhtikaura etc. It has yet to be seen whether the sudden inception of several plant-based protein product innovations will be defined as a pivotal era in the Finnish food industry or just a passing trend. Finnish media has aldo categorized MiFu as one of the up and coming fo…
Iron intake among Lebanese women: sociodemographic factors, iron-rich dietary patterns, and preparation of hummus, a Mediterranean dish
2021
Background: Plant-based foods such as hummus are alternative to animal protein, and when properly pre-pared, they help to alleviate nutritional iron deficiency that leads to anemia, a global health problem. Objective: The objective was to assess iron intake among Lebanese women and related participant’s charac-teristics, discern iron-rich dietary patterns, evaluate their association with nutrients intake and participant’s sociodemographic characteristics, and identify the women preparing hummus traditionally and properly for an enhanced iron bioavailability. Design: A cross-sectional study of 400 Lebanese women (18–74 years old) was conducted in Lebanon. Data from a questionnaire, including…
Vitamin A Deficiency and Alterations in the Extracellular Matrix
2014
Vitamin A or retinol which is the natural precursor of several biologically active metabolites can be considered the most multifunctional vitamin in mammals. Its deficiency is currently, along with protein malnutrition, the most serious and common nutritional disorder worldwide. It is necessary for normal embryonic development and postnatal tissue homeostasis, and exerts important effects on cell proliferation, differentiation and apoptosis. These actions are produced mainly by regulating the expression of a variety of proteins through transcriptional and non-transcriptional mechanisms. Extracellular matrix proteins are among those whose synthesis is known to be modulated by vitamin A. Reti…
The Role of Vitamin Deficiency in Liver Disease: To Supplement or Not Supplement?
2021
Over the past few years, growing interest has been shown for the impact of dietary requirements and nutritional factors on chronic diseases. As a result, nutritional programs have been reinforced by public health policies. The precise role of micronutrients in chronic liver disease is currently receiving particular attention since abnormalities in vitamin levels are often detected. At present, treatment programs are focused on correcting vitamin deficiencies, which are frequently correlated to higher rates of comorbidities with poor outcomes. The literature reviewed here indicates that liver diseases are often related to vitamin disorders, due to both liver impairment and abnormal intake. M…
