Glucose, fructose, sucrose, free asparagine, and free glutamine were analyzed in 74 potato samples from 17 potato cultivars grown in 2002 at various locations in Switzerland and different farming systems. The potential of these potatoes for acrylamide formation was measured with a standardized heat treatment. These potentials correlated well with the product of the concentrations of reducing sugars and asparagine. Glucose and fructose were found to determine acrylamide formation. The cultivars showed large differences in their potential of acrylamide formation which was primarily related to their sugar contents. Agricultural practice neither influenced sugars and free asparagine nor the potential of acrylamide formation. It is concluded that acrylamide contents in potato products can be substantially reduced primarily by selecting cultivars with low concentrations of reducing sugars.
The effect of irradiation on the patulin content and on the chemical composition of apple juice concentrate during storage at 4 degrees C over a period of several weeks was investigated. The radiation-induced disappearance of the mycotoxin in relation to the absorbed dose followed an exponential relationship. The radiation dose (D50), i.e., the dose which reduced the patulin content to 50% of its initial value was equal to 0.35 kGy. Storage of the irradiated concentrate had no effect on the patulin content; however, storage did lead to a slight increase in the titratable acidity and a decrease in the amounts of the carbonyl compounds and the ascorbic acid concentration. The development of non-enzymatic browning during storage of the irradiated samples followed the same kinetics as that of the non-irradiated samples.
We report the unusual occurrence of progressive megalencephaly and dilated periventricular cystic Virchow-Robin spaces on magnetic resonance imaging in two siblings of a Turkish family. Both affected children in addition presented with psychomotor retardation. Since the index patients were of different gender and their parents were consanguineous, this constellation of findings is suggestive of an autosomal recessive trait.
Objectives
Analysis of barriers, facilitators and concepts to implement delirium prevention programs in German and Austrian hospitals.
Materials and Methods
Qualitative, semi-structured expert interviews with 9 leaders of delirium prevention programs in Germany and Austria.
Results
Leaders described delirium incidence reduction, higher standards in hospital care for older patients, and improvement of employee satisfaction as goals for their delirium prevention pro-gram. Barriers were described with fragmented hospital care structures – regarding sections and professional background of the staff – and lack of financial resources. Facilitators were named with acknowledging delirium prevention successes of known community leaders and building interest groups and networks. For the implementation of their delirium prevention program, hospitals used working groups and networks to benefit from outside perspectives on their implementation process.
Conclusion
Although delirium prevention is associated with cost savings in hospital procedures, program leaders described a lack of financial resources to implement delirium prevention programs. To face the demographic shift in hospital care, it is vital to implement national health care funding for delirium prevention programs. Currently, hospital leaders described an undersupply of older patients with delirium in German and Austrian hospital care.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
