SUMMARY1. Alzheimer's disease (AD) is a degenerative disease of the central nervous system and its progression is often connected with a development of severe malnutrition. However, sufficient data on nutritional state and intervention regarding the progression of AD are not yet available. The aim of the present study was to assess the relationship between nutritional support and the improvement, or the maintenance, of patients' health.2. One hundred AD patients were included in a 2 year study. Voluntary food intake was measured during the first year, following which patients were randomized into one of two groups. The study group received a 600 kcal supplement to their regular diet, whereas the control group continued on the standard diet. Nutritional parameters, voluntary food intake and mental state were monitored every 2nd month of the study period.3. Patients with Alzheimer's dementia who died had been suffering from severe malnutrition during the last 3 months of their lives. A significant decline in mental functions was discovered in AD patients also suffering from malnutrition. Nutritional support significantly slowed the deterioration of the mental function of AD patients.4. The present study shows that patients with AD are undernourished despite normal voluntary energy intake. Nutritional intervention significantly decreased the progression of deterioration of the mental function of AD patients, as well as other complications. It is concluded that dietary counselling and nutritional support in patients with AD are clinically important and reduce the impairment of mental function.
The aim of the presented article is to evaluate the impact of climate change on the sugar content of grapes in the Czech Republic during the period 2000–2019 through selected indicators on the basis of available secondary sources. Attention is focused on the developments in both the main wine-growing regions of Moravia and Bohemia. In the field of viticulture and wine-growing, the sugar content of grapes, as a basic parameter for the classification of wines, plays an important role. In the Czech Republic, the average sugar content of grapes has had a constantly growing trend. This trend is evident both in the wine-growing region of Bohemia and in the wine-growing region of Moravia. The impact of climate change, especially the gradual increase of average temperatures in the growing season, cannot be overlooked. It greatly affects, among other things, the sugar content of grapes. Calculations according to the Huglin Index and the Winkler Index were used to determine the relationship between climate and sugar content. These indexes summarize the course of temperatures during the entire vegetation period into a single numerical value. The results show that both indexes describe the effect of air temperature on sugar content in both wine regions of the Czech Republic in a statistically significant way. The Huglin Index shows a higher correlation rate. The Winkler Index proved to be less suitable for both areas. Alternatively, the Winkler Index calculated for a shorter growing season was tested, which showed a higher degree of correlation with sugar content, approaching the significance of the Huglin Index.
Forests as a part of landscape do not fulfil their economic function (timber production) only but a lot of other non-economic functions, especially ecological ones. Both economic and non-economic functions are indisputable and equally important for society. The aim of this paper is to identify current attitudes to forest perceptions by citizens in the Czech Republic. Primary data were obtained by means of a questionnaire research survey which was carried out in 2018. Altogether 824 respondents took part in this survey (n = 824). From the results follows that approximately 70% of respondents visit forest at least three times a month. In connection with this, the relationship between respondents’ forest visit frequency and the forest density in the region where they come from was confirmed. 60% of respondents consider the forest exploitation and forest management to be the most important cause of damage and threats to forest. In relation to forest, 46% of respondents consider forest conservation and protection to be the most important topics.
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.
