Spectral Transmission of the Human Crystalline Lens in Adult and Elderly Persons: Color and Total Transmission of Visible Light
2012
Purpose To experimentally measure the spectral transmission of human crystalline lenses belonging to adult and elderly persons, and to determine the color and total transmission of visible light of such crystalline lenses. Methods The spectral transmission curve of 32 human crystalline lenses was measured using a PerkinElmer 800UV/VIS spectrometer. Total transmission of visible light and the chromatic coordinates of these crystalline lenses were determined from these curves for solar illumination. Results The crystalline lens that filters UV and its transmission in the visible spectrum decreases with age; such a decrease is greater for short wavelengths. The total transmission of visible li…
Consensus meeting: monosodium glutamate – an update
2006
Update of the Hohenheim consensus on monosodium glutamate from 1997: Summary and evaluation of recent knowledge with respect to physiology and safety of monosodium glutamate.Experts from a range of relevant disciplines received and considered a series of questions related to aspects of the topic.University of Hohenheim, Stuttgart, Germany.The experts met and discussed the questions and arrived at a consensus.Total intake of glutamate from food in European countries is generally stable and ranged from 5 to 12 g/day (free: ca. 1 g, protein-bound: ca. 10 g, added as flavor: ca. 0.4 g). L-Glutamate (GLU) from all sources is mainly used as energy fuel in enterocytes. A maximum intake of 6.000 [c…

Outdoor mobility and social relationships of elderly people.
1997
Social relationships and activities are important elements in the quality of life of older people. With advancing age, they are made more difficult through the possible loss of physical functions, through societal processes of differentiation, and through unfavourable environmental and technological conditions. Therefore, mobility becomes a fundamental prerequisite for the participation in social relations and activities. This article presents some initial findings of a project which investigates the mobility needs of the elderly and the main factors hindering their desired mobility in three European countries. It became apparent that there is a clear connection between the social situation…
Real-time 3D movements analysis for a medical device intended for maintaining functional independence in aged adults at home
2016
We propose in this manuscript a realtime3D movement analysis system for inhomefunctionalabilities assessment in aged adults. As a first step, the purpose is to maintain the functionalindependence of this population and to allow an earlier detection of a motor decompensation inorder to facilitate a rehabilitation process. To quantify the equilibrium quality of a subject, webuilt a system using the Kinect sensor in order to analyze a simple clinical test validated in geriatricrehabilitation: the Timed Up and Go (TUG). Three experiments conducted in heterogeneousenvironments (laboratory, day hospital and home) showed good measurement reliability of theidentified parameters. In particular, they…
Principles of Damage Control in the Elderly
2017
A steadily increase of severely injured elderly patients may be expected. Comorbidities are present in the majority of these patients and negatively influence outcome. Blunt trauma is the leading cause of high-energy injuries in the elderly. Motor vehicle accidents, either as driver or as pedestrian hit by a car, and falls from height are the most important mechanisms of polytrauma. The principles of advanced trauma life support (ATLS) should also apply for elderly persons. Underestimation of the severity of injury is a common problem leading to undertriage. A basic rule of primary care is to avoid the lethal triad of hypothermia, coagulopathy and acidosis. Emergent invasive monitoring redu…
Physical activity and dementia : Long-term follow-up study of adult twins
2015
Introduction. Physical activity is associated with a decreased occurrence of dementia. In twins, we investigated the effect of persistent physical activity in adulthood on mortality due to dementia. Materials and methods. Physical activity was queried in 1975 and 1981 from the members of the older Finnish Twin Cohort (n = 2 1,791), who were aged 24-60 years at the end of 1981. The subjects were divided into three categories according to the persistence of their vigorous physical activity. Dementia deaths were followed up to the end of 2011. Results. During the 29-year follow-up, 353 subjects died of dementia. In individual-based analyses the age-and sex-adjusted hazard ratio (HR) was 0.65 (…
Évaluation de la prescription du furosémide chez la personne âgée de 75 ans et plus dans un service de gériatrie aiguë
2018
Resume Introduction Le furosemide est tres prescrit en France. Il serait responsable d’effets indesirables non negligeables surtout chez la personne âgee. Afin de limiter son mesusage et un surcout pour la securite sociale, la Societe europeenne de cardiologie a edite des recommandations de prescription strictes. Nous avons conduit une etude dans une population âgee dont l’objectif principal etait de determiner le taux de prescription du furosemide chez la personne âgee hors recommandations. Methode Il s’agissait d’une etude prospective, monocentrique et observationnelle portant sur des personnes d’âge ≥ 75 ans, admises dans un service de geriatrie aigue sur une periode de 6 mois. La preval…
Anti-Inflammatory Effects of the Mediterranean Diet in the Early and Late Stages of Atheroma Plaque Development
2017
Objective.To evaluate the long-term effects of a Mediterranean diet (MeDiet) intervention on the plasma concentrations of inflammatory and plaque stability-related molecules in elderly people at high risk for cardiovascular disease.Design and Setting. 66 participants from primary care centers affiliated with the Hospital Clinic of Barcelona were randomized into 3 groups: MeDiet plus extra virgin olive oil (EVOO) or nuts and a low-fat diet (LFD). At baseline and at 3 and 5 years, we evaluated the changes in the plasma concentrations of 24 inflammatory biomarkers related to the different stages of the atherosclerotic process by Luminex®.Results.At 3 and 5 years, both MeDiet groups showed a si…
