The trans-fatty acids in subcutaneous fat and in fat content of breast milk as an indicator of their nutritional intake
Dlouhý, Pavel ; Anděl, Michal (advisor) ; Dostálová, Jana (referee) ; Hrubý, Stanislav (referee) ; Zadák, Zdeněk (referee)
Trans fatty acids (TFA) are unsaturated fatty acids, which have one or more double bonds in the trans configuration. Their main dietary sources are partially hardened fats and food products containing partially hardened fats (margarines, shortenings, bakery products, and fast foods). TFA are thought to increase the risk of coronary heart disease and type 2 diabetes. These fatty acids have adverse effects on blood lipid levels, increasing LDL-cholesterol while decreasing HDL-cholesterol. Consumption of TFA can also impair insulin sensitivity. High intake of TFA is associated with systemic inflammation, activation of immune functions and endothelial dysfunction. Hypotheses also exist that TFA may have adverse effect on the metabolism of essential fatty acids and foetus development. The concentration of TFAs in subcutaneous fat is a very good indicator of dietary exposure of TFA. This concentration reflects long-term dietary intake of these fatty acids. Levels of TFA in human milk are more variable; however, it is quite simple to obtain a sample of human milk. The purpose of our studies was to determine (a) content of TFA in subcutaneous fat samples from persons with coronary atherosclerosis and from persons with no sign of coronary dinase and (b) the content of TFA in early human milk of breast-feeding women...

Some aspects of the pathophysiology of macrovascular complications of type 2 diabetic patients and of their assertion in practice
Adamíková, Alena ; Svačina, Štěpán (advisor) ; Anděl, Michal (referee) ; Vízek, Martin (referee)
Pacienti s diabetem 2. typu a dalšími rizikovými faktory (dyslipidémie, mikroalbuminurie) mají vysoké riziko asymptomatického kardiovaskulárního onemocnění. Pozitivní mikroalbuminurie ve skupině asymptomatických diabetiků 2. typu byla prokázána u 11,6% pacientů a u všech se vyskytla různě závažná forma kardiovaskulárních onemocnění. Dysfunkce endotelu, aktivní zánětlivý proces v cévní stěně, poruchy lipidového spektra, porucha reverzního transportu cholesterolu se podílejí na akceleraci aterosklerotického procesu u diabetiků 2. typu. Vysoká hladina zánětlivého markeru hs-CRP 3,053±2,668 mg/l přetrvávající ve studovaném souboru i přes zavedenou terapii poukazuje na nutnost systematického a trvalého aktivního terapeutického přístupu k diabetikům 2. typu s rizikovými faktory. Statisticky významný vztah dlouhodobé kompenzace diabetu dle HbA1c a parametrů transientní ischemické dilatace levé komory (TID) u těchto pacientů dokumentuje riziko hyperglykémie pro pseudodilataci levé komory srdeční způsobenou difuzní subendokardiální ischemií (p=0,035). Aktivní přístup k těmto rizikovým pacientům jak po stránce diagnostiky (zátěžové EKG, zátěžový SPECT myokardu), tak po stránce terapie, může podstatně ovlivnit jejich další kvalitu života a životní prognózu.

Factors influencing the metabolism of homocysteine in selected diseases with complex etiopathogenesis
Veselá, Kamila ; Anděl, Michal (advisor) ; Nečas, Emanuel (referee) ; Rušavý, Zdeněk (referee) ; Poledne, Rudolf (referee)
At present, the great medicine to develop molecular genetic techniques, which significantly help to explain the causes of illnesses. In some diseases the genetic basis is well known. These are primarily contingent on monogenic diseases. Unfortunately, many diseases remain the genetic cause is still unknown. The largest group is the so-called complex diseases, where the origin and development of disease involving both genetic and nongenetic factors. These diseases include atherosclerosis, diabetes mellitus, orofacial clefts, preeclampsia, neural tube defects, and many others. Complex diseases are serious health and social problem in developed countries. Clasification of risk factors is the subject of much attention, because knowledge of these factors offer opportunities for effective prevention and treatment. The aim of my work was to obtain new knowledge of factors affecting homocysteine metabolism with regard to the formation of some complex diseases in the Czech population.

Tea, historical context and health aspects
Pitáková, Barbora ; Anděl, Michal (advisor)
Tea-right after water-is the most widely used beverage worldwide. Tea has its history, culture and probably also a unique healing power. Tea has been drunk all over the world. The goal of my work was to submit a preview of current knowledge about influence of tea on human body. Though consumed in a large extent around the world, we do not dispose of comprehensive knowledge of its effects on our health. By now, there have not been any complex studies which would lead to some conclusions generally applicable in medical practice. Recently a vast research of the effects of tea has been carried out and it might be possible that the tea could class also with modern therapy of some diseases. The resent results of studies which deal with the effects of tea on human body hold out hopes for potential use of tea and its components in prevention and therapy of human diseases because the tea embodies antioxidant, antiinflammatory and anticarcinogenic effects and furthermore some features influencing obesity and diabetes complications. These features and effects-in case of application and usage in clinical practice of prevention and therapy of relevant civilization diseasescould be of outstanding benefit for patients. It is, however, necessary to carry out clinical and epidemiological studies which would confirm these hopes.

Soft drinks and their effects on health
Ramstad, Gunnar Alexander Wilson ; Anděl, Michal (advisor)
The consumption of soft drinks has increased manifold over the last decades. In parallel to this increase it has been noticed an increase in health problems, especially obesity. Dentists continue to urge their patients not to drink soft drinks, and there has also been suggested a link between soft drink consumption and osteoporosis, hypokalemia and diabetes mellitus 2. Other additives, like caffeine, have been associated with headaches, restlessness and trouble with sleeping. Although more research is needed to confirm these relationships, many scientists suggest that we should start taking action to prevent children from developing the habits of large soft drink consumption we witness today. This could be accomplished by cooperation between parents, health practitioners, school system and government.

Nutritional Status of Prague Homeless Population
Hrnčířová, Dana ; Anděl, Michal (advisor) ; Derflerová Brázdová, Zuzana (referee) ; Provazníková, Hana (referee) ; Tláskal, Petr (referee)
Socio-economic, health and hygienic characteristics place the homeless people at risk groups. The higher incidence of health problems may have a multi-faceted etiology, including: smoking, alcohol, drugs, poor hygiene, insufficient food intake, poor quality diets etc. The prevalence of chronic diseases and cardiovascular risk factors is generally significantly higher in the homeless population than in the general population. Nutritional status of the homeless is also often compromised; many studies have reported malnutrition and insufficient intake of micronutrients whose daily turnover is enhanced by heavy smoking and alcohol consumption. The objective of our studies was to (a) define in the Prague homeless population the prevalence of protein-energetic malnutrition and (b) describe some of the major cardiovascular risk factors and to make comparisons between this group and the general Czech population, (c) to assess levels of selected vitamins (A, E, C, B1, B2, B6) and trace elements (Zn, Se, Cu) in blood and (d) exposition to Pb and Cd and to compare the results with individuals representing the general Czech population, (e) to assess the nutrient intake of main nutrients and compare it with the daily recommendations.

Occurence of malnutrition and carence states by elderly pacients admitted to hospital. Effect of hospitalization and possibilities of nutritional support.
Hrnčiariková, Dana ; Zadák, Zdeněk (advisor) ; Kalvach, Zdeněk (referee) ; Anděl, Michal (referee)
In hospitalized geriatric patients, malnutrition and deficiency states present a serious problem, which, in spite of its seriousness is at the margin of interest. It is necessary to ensure that hospitalization will not deteriorate nutritional deficit, and thus it will not increase the risk of complications of treatment and will not endanger the patient's life. Adequate dietary measures or nutrition support can prevent these problems. The present study aimed to evaluate the nutritional state of the elderly patients admitted to hospital and the effects of hospitalization and possible nutritional support on the changes in nutritional parameters and vitamin deficiency. A unique group of patients aged 80 years and older hospitalized at the standard ward of the Department of Gerontology and Metabolic Care, Faculty Hospital in Hradec Kralove, was studied. In the course of the study, approximately 70 anamnestic, anthropometric and laboratory parameters were examined, which were determined on the day of patients' admittance and then always in week's intervals. The obtained values were subjected to statistical analysis. The initial values of the parameters under study were evaluated, which show the condition of the admitted geriatric patient. The study focused on the relationship between positive and negative...
