Tree species can influence nutrient return to the forest floor and nutrient cycling through the amount and chemical composition of throughfall and litter. We compared foliar nutrient concentrations, litter production, nutrient return and soil chemistry under 7 tree species planted on the same site after two generations of a Norway spruce (Picea abies (L.) Karst.) monoculture. Common alder (Alnus glutinosa (L.) Gaertn.), european beech (Fagus sylvatica L.), pedunculate oak (Quercus robur L.), silver birch (Betula pendula Roth.), goat willow (Salix caprea L.) and rowan (Sorbus aucuparia L.) were planted within an experimental catchment on poor acid soil in south-eastern Belgium. Measurements were performed during one year, 11 years after planting. This study demonstrated that Ca, Mg, K and N concentrations in foliage and leaf litter are tree-species specific. Fresh foliage and foliar litter N concentrations were highest in alder and willow, while Ca, Mg and K concentrations were highest in rowan. Litter Ca concentrations were approximately twice in rowan than those of all other species. Differences in nutrient concentrations between foliage and leaf litter depended both on the element concerned and on tree species. The total average litterfall biomass ranged from 615 kg ha−1 year−1 under oak to 3122 kg ha−1 year−1 under rowan. Foliar litterfall represented above 85% for beech, spruce and oak, 70% for alder and willow and ca. 55% for birch and rowan. Reproductive parts formed 44% of total litterfall biomass under rowan. Ca, Mg, K and N return via throughfall, foliar litter and reproductive parts were higher under accompanying tree species (alder, birch, willow, rowan) than under the main commercial tree species (oak, beech, spruce). Total N return was in the order of 50 kg ha−1 year−1 under accompanying species, 33 kg ha−1 year−1 under spruce and near 20 kg ha−1 year−1 under beech and oak. Under rowan, total Ca, Mg, and K return to the forest floor through throughfall deposition, litterfall of leaves and reproductive parts amounted to 47, 9 and 66 kg ha−1 year−1, respectively. Compared to spruce, forest floor pHH20 has increased by 0.4 unit under birch and rowan, and exchangeable Ca2+, Mg2+, K+ have increased about threefold under rowan. Planting rowan as accompanying species may therefore represent an interesting management option for improving forest floor chemistry on nutrient poor sites through Ca, Mg, and K nutrient return.

The relationships among vertical stability, estimated nutrient utilisation and particulate organic matter in the Ross Sea are analysed from data collected during two cruises in the summers of 1987 - 88 and 1989 - 90. In the upper mixed layer (UML), identified through the vertical stability E(Z(UML)), nutrient consumption is calculated as the difference between the « diluted » nutrient value and the mean calculated from the integrated value in the UML. The nutrient utilisation ratio and E(Z(UML)) are linearly related for E(Z(UML)) < 25, whereas for values > 25, the distribution pattern is more scattered and independent of E(Z(UML)). For E(Z(UML)) > 25, utilisation values were > 4, 0.4 and 10 mmol m-3 for nitrate, phosphate and silicate, respectively. Significant relationships between nutrient depletion and both particulate organic carbon (POC) and particulate protein / particulate carbohydrate ratios (PPRT/PCHO) are found. The analysis of particulate matter distribution vs nutrient utilisation shows that the stations could be divided into two groups having different characteristics. The first group includes coastal stations, where high nutrient utilisation, POC and PPRT / PCHO are typical of areas with high production. In the second group (pelagic stations), nutrient utilisation, POC and PPRT / PCHO are lower. The vertical stability can be used to discriminate among the factors that influence primary production.

Ageing of the body predisposes to a high incidence of undernutrition in the elderly person wherever he or she is living, but the prevalence of malnutrition is particularly high in hospitalized or instutionalized patients. Early detection of malnutrition is important because malnutrition may have significant consequences and evaluation of nutritional status has to be a routine screening in the elderly. There is no single parameter which supplies a full assessment of the patient’s nutritional status. It is then necessary to use screening tools for the identification of patients at nutritional risk, based on anamnestic, antropometric and biologic data. The MNA (Mini Nutritional Assessment) test is a simple, non invasive, well-validated screening tool for malnutrition in the elderly and is recommended for early detection of risks on malnutrition. Numerous conditions in relationship with physiological ageing, comorbidity, polymedication and the way of life of the individual predispose to undernutrition. Healthy nutrition in older patients should respect the guidelines for protein and energy requirements, excepted in severely ill patients and/or in case of malnutrition in which case the protein-energy intake should be increased.

Les populations occidentales actuelles accordent de plus en plus d’importance à leur alimentation. Mais Il ne s’agit plus seulement d’intérêts organoleptiques ou hédonistes. Les consommateurs d’aujourd’hui sont plus que jamais attentifs au caractère nutritionnel de ce qui se trouve dans leur assiette. Preuve en est le nombre sans cesse croissant d’alicaments et d’allégations nutritionnelles et de santé qui apparaissant sur le marché. Autre exemple, la tendance graduelle de la part des entreprises agro-alimentaires de « décortiquer » un produit en ses différents nutriments essentiels, tels les protéines, les lipides, les sucres ou encore les fibres. Il est aussi de plus en courant d’y associer le pourcentage de l’apport quotidien recommandé contenu dans le produit. De nos jours, même l’importance des vitamines et des minéraux majeurs (Na, Ca, P, etc.) est ancrée dans les mentalités. Il y a cependant une catégorie de nutriments encore quelque peu délaissée : les oligoéléments. Les oligoéléments sont des éléments chimiques présents en très faibles quantités dans l’organisme mais dont le rôle est essentiel. Les plus connus sont l’iode, le fer, le cuivre le zinc ou encore le manganèse. D’autre par contre sont moins connus mais sont tout aussi indispensables (parfois en plus faible quantités encore) comme le molybdène, le nickel, le chrome, le cobalt et beaucoup d’autres. Les rôles de ces éléments sont aussi diverses qu’indispensables et on les retrouves dans des enzymes et cofacteurs (souvent dans le site actif), dans des hormones, mais ils peuvent aussi jouer un rôle structural (exemple du fluor dans l’hydroxyapatite). Parfois il n’y a qu’un pas à franchir entre oligoélément et élément toxique. C’est par exemple le cas de l’aluminium et de l’arsenic, qui sont nécessaires en petites quantités mais peuvent devenir des poisons (mortels) s’ils sont ingérés à plus forte dose. [less ▲]

BACKGROUND: Despite the remarkable technological progress in health care and treatment, cardiovascular disease remains the leading cause of premature death, prolonged hospitalization and disability in most European countries. In the population of the Greater Region (Grand-Duchy of Luxembourg, Wallonia in Belgium, and Lorraine in France), the prevalence of cardiovascular risk factors and disease is among the highest in Europe, warranting the need for a better understanding of factors contributing to this pattern. In this context, the cross-border "Nutrition, Environment and Cardiovascular Health-NESCAV" project is initiated by an inter-regional multi-disciplinary consortium and supported by the INTERREG IV A program "Greater Region", 2007-2013, to fight synergically and harmoniously against this major public health problem. METHODS/DESIGN: The objectives of the three-year planned project are to assess, in a representative sample of 3000 randomly selected individuals living at the Greater Region, 1) the cardiovascular health and risk profile, 2) the association between the dietary habits and the cardiovascular risk, 3) the association of occupational and environmental pollution markers with the cardiovascular risk, 4) the knowledge, awareness and level of control of cardiovascular risk factors, 5) the potential gaps in the current primary prevention, and finally, to address evidence-based recommendations enabling the development of inter-regional guidance to help policy-makers and health care workers for the prevention of cardiovascular disease. DISCUSSION: The findings will provide tools that may enable the Greater Region's decision-makers and health professionals to implement targeted and cost-effective prevention strategies. [less ▲]
