Causal interaction analysis of cardiovascular signals
Tiurina, Mariia ; Kolářová, Jana (referee) ; Svačinová, Jana (advisor)
Application of the non-invasive methods to detection of the baroreflex sensitivity is a correct way to evaluate the functions of cardiovascular system. This master’s thesis describes the theoretical informations about the problem of baroreflex sensitivity from anatomical, patalogical and clinical views. Theoretical knowledges are foundation for mathematical description of some methods to detection of baroreflx sensitivity in time, frequency and information dimensions. In the practical part of the master’s theses are presented two methods of BRS detection – sequence method based on finding the specific sequences of time series signals and method of application bivariante autoregressive model. Both of methods are implemented in MATLAB. The results of testing data on real data are discussed.
Hypertension and it´s conection to a healthy lifestyle
I have chosen hypertension and its connection with healthy lifestyle as the topic of my Bachelor thesis. Today, there is an increasing occurrence of lifestyle diseases that we mostly induce ourselves by our inappropriate lifestyle. In the developed world, a half of all deaths is caused by cardiovascular diseases where hypertension falls as a kind of warning signal of other lifestyle diseases. Appropriate lifestyle mostly comprises appropriate regimen, especially nourishment, as well as physical activity, enough sleep and stress elimination. In the Bachelor thesis, I used three goals of which the first one was to try to map following the principles of healthy lifestyle in patients suffering from hypertension. The second goal of the work was to assess 7-day diets and the last one was to inform about the importance and principles of healthy lifestyle as a preventive measure against the emergence of hypertension by means of the creation of an educational material. The theoretical part of the work is divided into two main chapters. The first one focuses on hypertension and summarizes the present state of the given problems, their definitions, classification, consequences and treatment. The second part deals with healthy lifestyle and negative factors of healthy lifestyle that lead to the emergence of hypertension. The practical part took place in the University Hospital Hradec Králové at the Department of Emergency Medicine in the outpatient department treating hypertension. I considered 140/90 mm Hg and higher to be a pathological value of blood pressure. The research file finally comprised 18 patients who brought their 7-day diets to the ambulance. The research was divided into two parts. For the first part of the research, a questionnaire method was chosen, aiming at dietary habits, physical activity and the knowledge the patients had about hypertension and prevention. In the second part, 6 patients were chosen by means of a simple random choice and their diets were analysed and assessed using nutrition software Nutriservis Professional. The assessment of the diets inquired if patients exceed their optimal daily energy intake, have enough all essential nutrients, what amount of sodium there is in their diets and if they follow the principles of rational nutrition. It followed form the questionnaire that patients are aware of their disease and prevention. As for their dietary habits, water intake and physical activity, the results were not that unambiguous for us to say that all patients follow the principles of healthy lifestyle. A food frequency questionnaire pointed out that patients suffering from hypertension consume food higher in salt than fats. It followed from the mapped diets that only two patients try to eat in accordance with the principles of rational nourishment, yet their diet exceeded the dietary reference intake of salt and fats. There even was a female patient at a great risk of malnutrition and another one had a completely inappropriate diet. As for the calculated diets, none of the patients follows the dietary principles related to hypertension and there are only two of them who try to do so as was stated above. Thanks to the creation of the educational material, the work can serve the public as a source of basic information. It can draw attention to the importance and beneficial effect of healthy lifestyle as a result of slowing down the development and emergence of lifestyle diseases.
Awareness of the risks of hypertension in humans selected age groups
Arterial hypertension is a lifestyle disease that is one of the most common cardiovascular diseases. It is also the most frequent cause of mortality and morbidity in the Czech Republic. Hypertension is often asymptomatic, so that is why it is crucial to communicate the risk factors of high blood pressure to the general public. The diploma thesis is divided into a theoretical and an empirical part. The theoretical part defines blood pressure and hypertension and describes the risk factors, examination methods, treatment and complications of high blood pressure. Next, it also focuses on the role of nurses in preventing hypertension, education of patients with hypertension and incidence of hypertension among various age groups. BothCzech and foreign scholarly sources from the field of nursing, medicine, psychology and sociology were used. Three objectives were chosen based on the obtained information. The first objective was to determine whether people in specific age groups are aware of risk factors affecting hypertension. The second objective was to identify whether people in specific age groups are educated on hypertension prevention. The last objective attempted to find out whether adults in specific age groups follow preventive measures. Five research questions were identified following these objectives. The information relating to this issue was obtained through a qualitative research survey. A semi-structured interview was chosen as a data collection method. The research group consisted of 12 general nurses, 16 people without hypertension and 16 patients with hypertension. With the consent of the respondents, the interviews were recorded on recording equipment. If the respondents did not agree with recording, the interviews were noted in record sheets. The interviews were carried out until the responses were saturated. The recorded conversations and the data in the record sheets were subsequently transcribed. The obtained data were coded and divided into categories and subcategories. For the purpose of clarity, these categories were processed into schemas using SmartArt. The final schemas were then described. The results showed that half of the people without hypertension in all age groups were usually informed about the risk factors of hypertension by their general nurse and doctor. The second half of the respondents were never informed about the risk factors of hypertension. Hypertensive patients most often reported that they were informed about the risk factors by their doctor. However, interviews with the general nurses showed that most nurses inform all people about the risk factors of hypertension. According to the nurses, older people need more information that needs to be repeated because they are worse at understanding. The interviews also showed that most nurses participating in the research educate adults about hypertension prevention. However, most of the people not suffering from hypertension as well as hypertensive patients in all age groups indicated that they have never been informed about the prevention of hypertension. Four general nurses stated that patients follow preventive measures. Other nurses said that it depends on the person some people follow these measures or follow them sometimes and some do not follow them at all. I assume that since the interviewed adults, who have been divided into selected age groups, do not have any information about the prevention of hypertension, they cannot follow any preventive measures. The output of the diploma thesis is an educational brochure that can help patients not suffering from hypertension as well as hypertensive patients to understand the aspects of this disease. This brochure can be used by nurses to educate people about the risk factors of hypertension. In addition, this diploma thesis could be used as a study material for students of the Faculty of Health and Social Sciences at the University of South Bohemia.
Health aspects of salt in food
Wűrzová, Anna ; Bušová, Milena (advisor) ; Králíková, Eva (referee)
Sodium chloride is an integral part of our nutrition and has an important function in the metabolism of the human organism. It contains sodium which is one of the basic minerals of the body. Although the salt is necessary for our body, its excess intake leads to a number of negative health effects. The theoretical part of the thesis describes the physiological importance of sodium chloride and the negative effect of salt on the body. It also deals with legislative requirements for salt, the recommended daily doses and trends in the consumption of salt. Last but not least, inform about therapeutic nutrition and the prevention of diseases associated with excess salt intake. The aim of the work is to make an overview of the importance and use of salts and the negative health effects of excess salt in human nutrition and further laboratory verification of the salt content in selected food and compared the measured results with the data on the salt content listed on the packaging. Part of the work is sample menus with different content of salt. The assembled full-day menus using the program Nutriservis represent, how to eat properly and to follow the health recommendations for salt intake according to the WHO and at the same time contain examples of bad menus with overdue daily amount of salt.

Salt intake in infants
KRÁLOVÁ, Veronika
This bachelor's thesis deals with salt intake for infants. This is a current topic as there are lots of discussions about excessive salt intake nowadays. Taste for salt is developed in childhood and it influences its subsequent perception. Long-term excessive salt intake in food can cause a risk of hypertension. According to professor Janda, recommended daily amount of salt for an infant should not be more than 1 g. The aim of this bachelor's thesis is to find out the intake of salt for infants. There were two research questions formulated: "What is the intake of salt in food for infants?" and "What is the difference between salt intake for infants being only breast-fed, infants being fed by complementary milk food and those being fed by non-milk complementary food. The thesis is divided into two parts, theoretical and practical. The theoretical one describes the issue of salt intake, the practical one contains qualitative research. The focus group was comprised of 12 infants who were divided into 3 groups of 4. Infants up to 4 months old were in the first group, infants between 4-8 months old were in the second group and infants between 8-12 months were in the third group. Every fourth infant was chosen from the database of supervisor's patients. Three-days diet records were received from the mothers of the infants. Based on these records the amount of salt was further calculated in the Nutriservis program. The results of the survey are presented in charts and in word evaluation. The research shows that, from the point of view of salt intake, mother's milk is ideal infant food. The recommended amount of salt was not exceeded for neither of the chosen infants. The infants being fed only with mother's milk had the lowest salt intake, whereas the infants being fed with non-milk complementary food had the highest salt intake. This bachelor's thesis can serve as a source of information for students of nutritional therapy as well as for mothers of infants.
Salt intake in women over 60 years and impact of food on their blood pressure
Worldwide reported about salt intake is higher than the recommended amount. Actually literature reported amount by 5 - 7 g of NaCl per day. Czech Republic has same recommended number of NaCl. My bachelor thesis is about to find out how is the salt intake for selected respondents over 60 years old and how this quantity have effect to their blood pressure. I chose a qualitative research method, where I tracked salt intake, urine waste and blood pressure values. I didn´t use any nutritional databases, when I got the amount of salt I received. I checked the packages of foods that reported the amount of salt. Thanks to EU Regulation 1169/2011, it is now the duty of the manufacturer write quantity of NaCl on the packages of product. I also weighed all the salt we added to the foods. On the basis of these calculations, I determined the intake of NaCl per day and total of four days. I chose those foods, which salt intake was on the packages and I knew exactly amount. I measured the blood pressure, at the same time. The values from the morning, at noon and in the evening I wrote. Eventually, I collected urine, which was subsequently examined for mineral waste on the last day. As a check to see if the waste corresponds to intake, serve test results from laboratory. On the basis of the research, we found out that the recommended personal daily intake of NaCl was not exceeded, in this age category. The blood pressure values did not correspond to hypertension, and the results from the laboratory, correspond to the amount of salt received.
The influence of loneliness on hypertension in the elderly
Vajdíková, Markéta ; Šteffl, Michal (advisor) ; Daďová, Klára (referee)
Title: The influence of loneliness on hypertension in the elderly Objectives: The main aim was to estimate the influence of loneliness on hypertension in people over 50 years old. Methods: This Bachelor thesis was constructed as a cross-sectional study. Data were obtained from the 6th wave of the international project Survey of Health Ageing and Retirement in Europe (SHARE). Generalized linear models for binominal variables were used to estimate the influence of loneliness on hypertension. Results: Data from 32,431 women and 26,245 men were included in the analyses. The average age was 67.3 ± 9.6. Almost all the regression models showed statistically significant (p˂0.05) influence of loneliness on hypertension, except in males after adjusting for age and the other covariates. The highest influence of loneliness on hypertension was found in females where OR = 1,649 (p ˂0.001). Conclusions: The results of this study showed that loneliness could have a statistically significant influence on hypertension in females over 50 years old. Keywords: hypertension, loneliness feeling, SHARE
The salt intake in school children´s diet
It is generally known that the intake of salt in civilized countries has been currently multiple times exceeding the recommended amount that was set by the World Health Organization to less than 5 grams per a day. In Czech Republic this dose has been exceeded up to three times. The aim of this bachelor thesis is to evaluate the amount of the salt in lunches at school cafeterias in regards to the current nutritional recommendations. The thesis is divided into two parts, theoretical and practical. The theoretical part is about importance of sodium and salt in human diet, recommended amount of salt for adults and children, and complications related to its excessive intake. Furthermore it focuses on the occurrence of salt in food, the reduction of the salt in the diet and the nutrition of children. In the practical part I worked with five school canteens in České Budějovice, that provided me with weekly menus along with the list of raw materials and the quantity of salt used in individual lunches. The sodium content was evaluated by the Nutriservis Professional application, in which I inserted the raw materials the lunches were cooked from. According to the equation, I converted the amount of sodium to the amount of salt, added the amount of salt contained in average portion served at school canteens and compared the total amount to 1,7 grams, which is supposed to be in one portion. Based on the results of the verbal evaluation tables, all the school canteens of the research group exceeded the recommended salt limit in all the observed days. Groups of foods that have greatly influenced their high salt content include bakery products, cheeses and meat products. More attention needs to be paid to this subject, on the part of parents, and school canteens.
Spa treatment of patients with metabolic syndrome
This diploma thesis deals mainly with patients with diagnosed metabolic syndrome disease in connection with the importance of spa treatment in Mariánské Lázně. The objectives of this work are: to find the most commonly used spa method for patients with metabolic syndrome, to find out the current lifestyle of patients with metabolic syndrome and to find out whether the health condition of patients who have undergone spa treatement was improved during their spa stay. A qualitative survey method was used to achieve the objectives. Data collection was conducted through interviews of patients with metabolic syndrome and visitors to Parkhotel Golf a.s., Mariánské Lázně. I consider the increased consumption of white bread, alcohol and cigarettes in some respondents to be the fundamental findings of my research. Most respondents do not consume vegetables in sufficient quantity, and deficiencies are also evident in dedicating to sporting activities. Information about the metabolic syndrome itself or the complications of the individual components of this syndrome is sufficient. In connection with metabolic syndrome, it was found out that not all patients who underwent spa treatment want to change their lifestyle after returning from the spa facility. Considering the findings from spa patients, I would recommend to increase the education of patients with metabolic syndrome, to emohasize to them the importance of healthy nutrition, smoking abstinence, or enough movement as the basis for preventing this disease. A lecture which has been created on the basis of interview information and is part of the supplement to this work can be used as means for patients with metabolic syndrome.
