Fear of exercise and health-related quality of life in patients with an implantable cardioverter defibrillator
Several studies have reported improved survival rates thanks to the use of an implantable cardioverter defibrillator (ICD) in the treatment of patients with life-threatening arrhythmia. However, the effects of the ICD on health-related quality of life (HR-QoL) of these patients are not clear. The aim of this study is to describe HR-QoL and fear of exercise in ICD patients. Eighty-nine ICD patients from the University Hospital in Groningen, the Netherlands, participated in this study. HR-QoL was measured using the Rand-36 and the Quality of Life After Myocardial Infarction Dutch language version questionnaires. Fear of exercise was measured using the Tampa Scale for Kinesiophobia, Dutch version and the Fear Avoidance Beliefs Questionnaire, Dutch version. Association between outcome variables was analysed by linear regression analyses. Study results show that the HR-QoL of patients with ICDs in our study population is significantly worse than that of normal healthy people. Furthermore, fear of exercise is negatively associated with HR-QoL corrected for sex, age and number of years living with an ICD. After implantation of the ICD, patients with a clear fear of exercise should be identified and interventions should be considered in order to increase their HR-QoL
Monitoring, analysis and modeling of yield and quality dynamics of Lolium perenne varieties for biogas production
Compilation of a Database of Research Information on Legume Based Grazing Systems; a Part of the Leggraze Research Project
The establishment of a publicly accessible web-resident database of published and current European research on agronomy, animal production and environmental impact of legume based grazing systems is reported. This database facilitates the sharing of information among the partners of the Low input animal production based on forage legumes for grazing systems (Leggraze), a research project funded by the UE (QL K5 CT-2001-02328). It also forms an important tool for transferring the results of the project to the wider research community and to end users in the agricultural sector and to policy makers at national and community level
An \u3cem\u3ein vitro\u3c/em\u3e Study on the Influence of Residual Sugars on Aerobic Changes in Grass Silages
How do residual sugars in high dry matter grass silages influence microbial metabolism? To answer this question a simple laboratory method was developed using pH as main indicator for aerobic changes
Development of a Method for the Fast and Complete Assessment of Quality Characteristics in Undried Grass Silages by Means of an NIR-Diode Array Spectrometer
Traditionally, the determination of grass silage is very time consuming and needs a lot of manpower and chemicals. The advantages of conventional laboratory NIRS instruments are well known but their disadvantage lies in their lacking suitability for on-farm use. A new type of spectrometer based on diode arrays may be used for this purpose. However, these new instruments still need to be calibrated for an accurate estimate of the fermentative and nutritive value of wet and unchopped grass silage
Effect of Residual Sugar in High Sugar Grass Silages on Aerobic Stability
New varieties of Lolium perenne, bred for high sugar content, can contain up to 30% of water soluble carbohydrates (WSC). Only a fraction of such high contents are metabolised during a normal fermentation and the high residual sugar content (RSC) of these silages can improve the efficiency of use of nitrogen by ruminants. However, these RSC at opening for feed-out could be preferentially metabolised relative to fermentation products by all aerobically growing fungi and bacteria present on the forage. A high RSC thus can increase the risk of aerobic deterioration over that of extensively fermented silages, containing predominantly organic acids, which are initially utilised by certain yeasts. The objective of this study was to assess the relationship between RSC and aerobic stability of silages prepared with either optimal ensiling conditions or with a defined air challenge treatment to make them prone to aerobic deterioration. The latter is a useful method to test the efficacy of aerobic stability improving silage additives, requiring unstable controls (Pahlow et al., 1999)
Wie werden die GesamtnÀhrstoffgehalte des Ackerbodens durch Biomasseein- und -austrÀge im Agroforstsystem beeinflusst?
Der RĂŒckgang organischer Bodensubstanz durch den kontinuierlichen Entzug von NĂ€hrstoffen und Biomasse mit dem Erntegut ist eine der Hauptursachen fĂŒr die Degradierung intensiv genutzter Ackerböden. Agroforstsysteme können ein SchlĂŒssel zu einer nachhaltigen Erhöhung der Bodenfruchtbarkeit sein, da zusĂ€tzliche Ausgangsstoffe fĂŒr die Bildung organischer Bodensubstanz wie Laubstreu und Wurzelexsudate dem Agrarökosystem zugefĂŒhrt werden. Im Rahmen des BonaRes-SIGNAL-(âSustainable intensification of agriculture through agroforestryâ) Projektes werden die QuantitĂ€t und QualitĂ€t der oberirdischen Biomasseein- und -austrĂ€ge fĂŒr zwei Alley Cropping-Agroforstsysteme mit Ackerkulturen bzw. GrĂŒnland in Niedersachsen bestimmt. Es werden rĂ€umliche Ertragsanalysen der Ackerkulturen und GrĂŒnlandbestĂ€nde durchgefĂŒhrt und die rĂ€umliche und zeitliche Verteilung und Zersetzung der Laubstreu gemessen. Das Poster prĂ€sentiert erste Ergebnisse zur Beeinflussung der GesamtnĂ€hrstoffgehalte des Ackerbodens durch die zusĂ€tzlichen BiomasseeintrĂ€ge der schnellwachsenden BĂ€ume und die BiomasseaustrĂ€ge durch die Ernte der Ackerkulturen, sowie zu der Frage welche Ackerbodenbereiche neben den Kulturpflanzen auch von den BĂ€umen durchwurzelt und somit als NĂ€hrstoffquelle genutzt werden
Effects of organically and conventionally produced feed on biomarkers of health in a chicken model
Consumers expect organic products to be healthier. However, limited research has been performed to study the effect of organic food on health. The present study aimed to identify biomarkers of health to enable future studies in human subjects. A feeding experiment was performed in two generations of three groups of chickens differing in immune responsiveness, which were fed identically composed feeds from either organic or conventional produce. The animals of the second generation were exposed to an immune challenge and sacrificed at 13 weeks of age. Feed and ingredients were analysed on macro- and micronutrients, i.e. vitamins, minerals, trace elements, heavy metals and microbes. The chickens were studied by general health and immune parameters, metabolomics, genomics and post-mortem evaluation. The organic and conventional feeds were comparable with respect to metabolisable energy. On average, the conventionally produced feeds had a 10 % higher protein content and some differences in micronutrients were observed. Although animals on both feeds were healthy, differences between the groups were found. The random control group of chickens fed conventional feed showed overall a higher weight gain during life span than the group on organic feed, although feed intake was mostly comparable. The animals on organic feed showed an enhanced immune reactivity, a stronger reaction to the immune challenge as well as a slightly stronger âcatch-up growthâ after the challenge. Biomarkers for future research were identified in the parameters feed intake, body weight and growth rate, and in immunological, physiological and metabolic parameters, several of these differing most pronounced after the challeng
