Cognitive impairment is considered as essential feature of non-motor symptoms in Parkinson's disease (PD). It is a result of underlying pathological processes in the brain of PD patients and it leads to decreased quality of life. In this thesis an analysis of the structure and profile of cognitive impairment is presented with special emphasis on executive functions and memory. We take diagnostic entities developed for the description of PD cognitive spectrum such as mild cognitive impairment (PD-MCI) and dementia (PD-D) as examples of heterogeneity and different severity of cognitive impairment in PD. However, neuropsychological methods in Czech version that would measure these diagnotic units were not adequatly validated. In the experimental part we test a hypothesis, if gait disorder with falls in PD is interconnected with cognitive impairment, and if PD-fallers have more severe cognitive deficit than PD-non-fallers. On the basis of nine validity or normative data studies we show psychometric properties and clinical utility of several basic neuropsychological methods in the Czech population for memory (Rey Auditory Verbal Learning Test, California Verbal Learning Test, Second Edition, Memory For Intentions Screening Test and Enhanced Cued Recall Test), sustained attention and executive functions...

In Introduction, the author of this dissertation deals with postoperative venous thromboembolism (VTE), hereditary and acquired risk factors, prophylaxis regimens and recent recommendation of VTE prevention in surgery. In Practical part of this work the author assesses the risk of VTE in surgical patients according to risk assessment model. Genetic testing is carried out in all patients to determine the incidence of hereditary thrombophilia and coagulation markers are measured in 28-days postoperative period. Prevalence of VTE in 1-year postoperative period is observed. The results are analysed in group of patients with benign disease (hernia and gallstone disease) and group of patients with malignancy (colorectal cancer and pancreatic cancer) separately. The objective of this work is to determine the incidence of the most frequent thrombophilic mutations (factor V Leiden mutation and protrombin G20210A mutation) and assess the impact of hereditary thrombophilia on incidence of postoperative venous thromboembolism in general surgery. Validation of venous thrombosis risk assessment model recommended by Czech Society for Thrombosis and Hemostasis is further objective.

Objective: Mutations in the parkin (PARK2) gene have been associated with autosomal recessive early-onset Parkinson's disease (EOPD) with various frequencies in different populations. The aim of the study is to describe phenotypic characteristics of Czech EOPD patients, to evaluate the influence of environmental risk factors, and to determine the frequency of parkin allelic variants in patients and healthy controls. Methods: A total of 70 EOPD patients (age at onset ≤ 40 years) and 75 controls were phenotyped and screened for the sequence variants and exon rearrangements in the parkin gene. Results: The main features in the phenotype of the patients' sample were: the absence of cognitive deficit, high occurrence of dystonia, depression, hyperhidrosis, an excellent response to dopaminergic therapy, early onset of dyskinesia and motor fluctuation. Patients with mutations in the parkin gene had significantly lower age at onset. The agricultural occupation and work with chemicals increased the risk of EOPD, however the coffee drinking appeared to be a protective factor. Parkin mutations were identified in five patients (7.1%): the p.R334C point mutation was present in one patient, four patients had exon deletions. The detected mutations were observed in the heterozygous state except one homozygous...

Media are considered to be the public's primary source of information regarding mental illness. Evidence suggests that media representations of people with psychiatric disorders are frequently negative and contribute to their stigmatization. On the other hand, media can play an important role in reducing this stigmatisation by providing adequate information about this topic and engaging in antistigma campaigns. Up to now there was no standardised measurement of the stigma of mental illness in print media using clearly operationalized definitions. The objectives of this project were twofold; to develop a standardised and objective instrument to measure stigma of mental illness in print media; and to conduct an analysis of the current coverage on mental health/illness issues in Czech, Croatian, and Slovak print media. The development of the Picture of Mental Illness in Newspapers (PICMIN) instrument was based on the principles of content analysis, a research technique for making replicable and valid inferences from text to the kontext in their use. The instrument consists of eleven descriptive and five analytical categories. The most interesting findings based on the analysis of media representations of mental illness were; a similarly high level of stigmatizing articles across countries, clearly...

Neuropsychological aspects of preclinical stages of neurodegenerative diseases are an extensively studied topic in neuropsychological research. Neuropsychological assessment can be helpful for the estimation of conversion risk in individual cases. The focus of neuropsychological research shifted from the evaluation of dementia to mild cognitive impairment (MCI) or even to the detection of cognitive change before significant cognitive decline. In the theoretical part is presented a contemporary outline of preclinical stages of neurodegenerative diseases. The construct of MCI is the most studied topic in the prodromal stage of neurodegeneration and this part is dedicated to comprehensive analysis of MCI. The empirical research includes five studies on screening methods of cognitive abilities, memory and verbal fluency tests. We present normative and validity data in older adults and show their detection potential in MCI or preclinical stages of neurodegenerative diseases. Furthermore, we tried to show the detection potential of different memory measures in patients with MCI and estimate the relations between hippocampal atrophy and memory performance.

Gait and balance disorders and the resulting falls are a substantial part of Parkinson's disease (PD) and other movement disorders. Especially in the late stage of PD more than 80 % of the patients fall. History of falls remains the best predictor of falls nonetheless, but it can not be used in falls prevention. Dopaminergic pharmacotherapy improves postural stability and gait in PD only in the early stage and the dopaminergic responsiveness of these symptoms decreases significantly during the disease progression. The impact of this medication on future falls risk remains still unclear. The connection between balance and gait disorders and cognitive impairment in PD is also not fully understood. The current state of knowledge about gait and balance disorders and cognitive impairment in PD is not satisfactory. Therefore the aims of the experimental part of this thesis were prospective monitoring of risk factors and predictors of falls, observation of the impact of dopaminergic medication on future falls risk and verifying the relationship between gait and balance disorders and cognitive impairment in PD. The fourth aim of the thesis was to specify the type and severity of gait and balance disorders in patients with essential tremor (ET). Although ET is one of the most common neurological disorders,...

(English) This diploma thesis deals with the issue of mental disorders and services provided to family members of people with mental disorder within a non-profit sector. The first part includes theoretical chapters which are processed by analysing available literature. The chapters inform about mental disorder, quality of life, and describe the care of people with mental disorders - particularly social skills and communication, housing, education, employment and leisure time. The theoretical part also focuses on social work with the mentally ill and includes a role of a social worker. In conclusion, the theoretical part describes the possibilities of supporting family members within the system of the care of persons with mental disorder, especially educational and psychoeducational programmes. The empirical part maps the current range of services for family members of people with mental disorder, and in connection with that, it determines what workers consider to be their benefit. Then, the views of family members on the psychoeducational programme and the current system of taking care of persons with mental illness were examined in a parent organization. To implement the research, I chose a qualitative approach. The method used was a questionnaire survey and group interviews. The results showed...

Acute leukemias (AL) comprise a heterogeneous group of hematologic malignancies, and individual patient responses to treatment can be difficult to predict. Monitoring of minimal residual disease (MRD) is thus very important and holds great potential for improving treatment strategies. Common MRD targets include immunoglobulin heavy chain or T-cell receptor gene rearrangements, recurrent cytogenetic abnormalities and mutations in important hematological genes. Whereas in the majority of adult acute lymphoblastic leukemia patients a suitable MRD target can be identified, in adult acute myeloid leukemia patients well-characterized targets are found in only half of cases. The identification of new specific molecular markers of leukemic blasts for MRD assessment, particularly in AML patients, is therefore highly desirable. Our aim was to develop a flexible strategy for mapping of cytogenetically identified unique clone-specific abnormalities down to the single nucleotide level and, based on the sequence, design a specific real-time PCR assay for MRD assessment in AL patients without any previously described MRD marker. Using a combination of cytogenetic (chromosome banding, chromosome microdissection), molecular cytogenetic (mFISH, mBAND) and molecular biological (next- generation sequencing, long-range...

The basal ganglia (BG) are a group of brain nuclei situated deep in the cerebral hemispheres. While BG were primarily associated with motor functions, in recent years there has been an increasing evidence that BG are also significantly involved in a wide range of non-motor functions. This work focused on some of the non-motor symptoms associated with two typical basal ganglia disorders: Parkinson's disease (PD) and Huntington's disease (HD). The first study concerned spatial navigation impairment in patients with HD. Their spatial navigation skills were tested using the Blue Velvet Arena, technique evaluating spatial navigation in real space, capable to selectively differentiate between two components of spatial navigation - allocentric (environment-oriented) and egocentric (self-oriented). Allocentric navigation is linked to hippocampal function, whereas egocentric navigation is usually associated with striatum, a structure predominantly affected in HD. We found that spatial navigation is not significantly affected in the early stages of HD and that in more advanced stages, when spatial navigation is already impaired, there is no significant difference between allocentric and egocentric navigation impairment. We speculate that the striatal involvement does not contribute to the impairment of the...

Employer's lability for damages of an employee's health The purpose of my thesis is to analyze contemporary legal regulation of employer's lability for damages of employee's health with its former regulation in the labor code from 1965 and its future regulation in the code 266/2006 Sb. The thesis is composed of eleven chapters. Chapter one is introductory and characterises the basic sources of law in this sphere. The chapter is subdivided into three parts - International agreements, European law and National legal regulation. Chapter two examines a description of terms occupational accident and occupational diseases. This chapter is subdivided into trhree parts. Part one gives a description of occupational accident, damage and causality between occupational accident and damage, which are necessary preconditions of employer's lability for occupational accident. The subsequent part is about occupatinal diseases and the employer's lability for them. In this part is also a list of occupational diseases. The third part of the chapter gives an attention to special institute of endangerment by occupational disease. The subsequent chapter is about dues of employer and employee by the occupational accidents and diseases. Chapter Four concentrates on problem for employer's liability and the employer's...
