Týblová, Michaela ; Kubala Havrdová, Eva (advisor) ; Vymazal, Josef (referee) ; Taláb, Radomír (referee)
Introduction: Multiple sclerosis (MS) is associated with impaired bone health in comparison to an equally healthy population, even already in patients at the onset of this disease. The main risk factors for development of osteoporosis in MS patients are known. The aim of the study was to find the relationship of the decrease in bone mineral density (BMD) to the administered cumulative dose of steroids and to other risk factors in MS, mainly to the degree of motor deficit. Further goal was to evaluate the occurence of the risk of low-trauma fractures in multiple sclerosis patients.. The BMD and muscle mass was compared in MS patients (women and men) and control subjects, to examine the effect of main ones - physical disability and long-term glucocorticoid (GC) therapy on BMD. Clinical values of bone remodeling markers were evaluated in assessment of rate of bone loss in patients with multiple sclerosis long term treated with low dose of GC. Patients and methods: We used dual -energy X-ray absorptiometry for a measurement of BMD in 591 MS patients (455 females and 136 males) in 2004 and in cross-sectional longitudinal study published in 2014 with 474 patients (353 women and 121 men). Out of the whole study group body composition was evaluated in 250 MS females, 104 males and 247 healthy controls (193...

Multidisciplinary rehabilitation for pubescents patients with cerebral palsy
Buzková, Tereza ; Nývltová, Lucie (advisor) ; Zounková, Irena (referee)
Cerebral palsy is a non-progressive motor funciton development disorder which is caused by disruption of the immature brain. There is about 16 000 - 20 000 patients living in the Czech Republic with this diagnosis to date. Based on the clinical picture, specific forms of this disorder can be classified. Besides the motor funciton development disorder, the patients also suffer from other comorbidities (such as epilepsy, oropharyngeal dysphagia, sensory deficits etc.). Early diagnosis of this disorder is crucial. The severity of the motor function deficit is evaluated by monitoring the gross and fine motor function. Cerebral palsy is a non-progressive, not unchanging, disorder. The theoretic part of the thesis describes secondary issues which are present during pubescent period of the patients. They are dealing with growth disorders, reduced bone density and increased bone fragility. Plenty of risk factors precede these problems. Also, question of sexuality, life priorities and about future play a big role for the patients in their pubescent period. There are possibilities to solve these problems in terms of complex rehabilitation care. Especially in physiotherapy, occupational therapy and nutritional therapy. The practical part of the thesis is an example of an intensive rehabilitation care of a...

Regulation of cathepsin K activity by reactive inhibitory molecules applicable in biomedicine
Benýšek, Jakub ; Mareš, Michael (advisor) ; Obšilová, Veronika (referee) ; Kutil, Zsófia (referee)
3 Abstract Human cathepsin K (KatK) is a lysosomal cysteine protease expressed predominantly in osteoclasts. It is the most effective enzyme for collagen breakdown and its physiological function lies in the degradation of the extracellular bone matrix. Increased enzymatic activity of KatK is associated with osteoporosis, rheumatoid arthritis, and osteoarthritis. This makes KatK a target for the treatment of pathologies, and chemotherapeutics based on protease inhibitors are being developed for its regulation. This work deals with reactive peptidomimetic and low molecular weight inhibitors of KatK namely thiadiazoles, vinyl ketones, and cyanohydrazides. It focuses mainly on the determination of the binding mode of selective inhibitors and characterization of their key interactions with the active site of KatK. Crystallographic structural analysis was combined with approaches of computational chemistry, enzymological analysis, and cell-based assays to elucidate the relationship between structure and biochemical activity of the investigated inhibitors. The obtained results provide important information for the design and optimization of new highly effective and selective KatK inhibitors as potential drugs and diagnostic probes. Keywords: cathepsin K, protease, inhibitor, 3D structure, osteoporosis

Use of biochemical markers (Lipoprotein phospholipase A2 and hyaluronic acid) for laboratory diagnosis of metabolic and degenerative diseases of the musculoskeletal system
Kotaška, Jan ; Trč, Tomáš (advisor) ; Klapková, Eva (referee) ; Karpaš, Karel (referee)
Use of biochemical markers (Lipoprotein phospholipase A2 and hyaluronic acid) for laboratory diagnosis of metabolic and degenerative diseases of the musculoskeletal system Abstract Musculoskeketal disorders currently belong to the most common diseases. The presented work describes the use of biochemical markers (Lipoprotein phospholipase A2 and hyaluronic acid) for laboratory diagnosis of metabolic and degenerative diseases of the musculoskeletal system. Concentrations of LP-PLA2 were significantly elevated in the patients with bone resorption compared to the control group of healthy individuals. Serum levels of Lp-PLA2 also negatively correlated with decreased levels of serum osteocalcin in patients. HA concentrations in synovial fluid did not differ from published reference values in synovial fluid. Patients who underwent arthroscopy had significantly elevated synovial HA concentration than patients who underwent total knee endoprosthesis. HA positively correlates with osmotic pressure determined by examination of osmolality in synovial fluid. Lipoprotein phospholipase A2 concentrations are elevated in patients with bone density impairment. LpPLA2 concentrations correlate with the severity of bone density impairment expressed by the T score. Hyaluronic acid concentrations in patients with knee...

The role of nutrition in the prevention of osteoporosis: calcium, proteins and gut microbiota
Holánová, Karolína ; Zikán, Vít (advisor) ; Vágnerová, Tereza (referee)
Introduction: Osteoporosis is defined as a systemic metabolic disease of skeleton. It is characterized by reduced amounts of bone mass and degradation of bone tissue microarchitecture with increased chances of fractures occurring. Women after menopause are affected by lack of estrogen and therefore have increased risk of osteoporosis. Goal: The goal of the diploma thesis is to evaluate the nutritional state of women after menopause with osteoporosis (With OP) and without osteoporosis (Without OP) focusing on calcium, proteins and nutrients which are affecting gut microbiota (prebiotics and probiotics). Methods: Nutritional state was evaluated based on three-day diet analysis and questionnaire about dietary preferences. Amounts of particular nutrients in respondents diets were obtained by using web page www.kaloricketabulky.cz. Bone material densities were measured by dual energy X-ray absorptiometry (DXA). Results: Nutritional breakdown of diets did not show any statistically significant differences in most of the cases. The only exception was protein and fiber intake, where the group without OP reported higher intake. Both sets of respondents reported higher intake of calories, fats and proteins then recommended. On the other hand, low intake of carbs, fiber, calcium and probiotics was discovered...

The role of nutrition in the treatment of osteoporosis
Večeřová, Vendula ; Zikán, Vít (advisor) ; Kytnarová, Jitka (referee)
Introduction: Osteoporosis is one of the most frequent bone metabolic disease. It is a systemic metabolic skeleton disease, where the architecture of bone tissue is damaged due to the loss of bone mass, and therefore the bone quality is reduced. Thus, it comes to increased bones fragility and reduction in mechanical resistance, which leads to a higher risk of fractures. The principle of pathogenesis is an imbalance between resorption and bone formation. Due to increasing lifetime and lifestyle changes, the prevalence of the disease increases. Aim: The aim of the practical part of the diploma thesis is to evaluate the eating habits of postmenopausal women treated for osteoporosis and to evaluate their nutritional condition in relation to bone mineral density (BMD). Methods: Nutritional habits were obtained and evaluated through a questionnaire survey. Three-day meal records were collected and analysed using the Nutriservis Profesional nutritional software, to determine the energy intake and selected nutrients. Osteodensitometric data were measured using dual emission X-ray absorptiometry (DXA). Results: The analysis of the diet showed that the observed group of women consumes an excessive amount of energy on average, especially in form of fats. Higher intake of protein was also observed....

Bone density in persons after spinal cord injury
Starková, Kateřina ; Coufalová, Klára (advisor) ; Šteffl, Michal (referee)
Title: Bone density in people after spinal cord injury Objective: The purpose of this paper is to determine the levels of bone mineral density in people following a spinal cord injury. The levels are measured using a DXA device and the results are subsequently evaluated. Methods: The thesis is composed of eight independent case studies. A non-standardized 14 open and closed question survey was used for quantifying purposes. Answering the questions was a necessary prerequisite for participation in the survey. The measured results of bone density and body composition were used for data analysis, together with the survey, in comparison with other studies. Results: Eight probands (four women and four men) participated in the research. Based on the obtained data, we can state that all probands (n=8) record a decrease in bone mineral density to the level of Osteopenia. Better bone mineral density measurements have not been confirmed in individuals with lower spinal cord lesions. Probands who regularly engaged in sports and daily training before spinal injuries have better results in densitometric measurements. Furthermore, it can be confirmed that probands with a past compression fracture have worse measurement results than probands without a past fracture. However, due to the low number of measured...

Prokopová, Michaela ; Vágnerová, Tereza (advisor) ; Kvasničková, Ivana (referee)
Vitamin D and calcium are essential for the health of the elderly population. Due to the changes that occur in the body during aging, it is necessary to monitor the intake of these micronutrients and, if necessary, to supplement or substitute them appropriately. This thesis focuses on prevention of vitamin D and calcium deficiency in old age. The theoretical part explains the function of vitamin D and calcium in the human body, their metabolism, sources and problems of deficiency or excess. There is information about diseases related to the deficiency, especially osteoporosis and sarcopenia. The practical part has two sections. The first analyses the data from the SPRINTT trial. Data related to vitamin D, calcium, their supplementation and sarcopenia, as a disease associated with vitamin D deficiency, were used. The second section analyzes the data from a questionnaire survey in nursing homes, which obtained information about the health of seniors, the frequency of consumption of selected foods and vitamin D and calcium supplementation. Using data from the SPRINTT, it was found that 55 % of men and 40 % of women had the values of sarcopenia. 11 % of the participants had vitamin D deficiency. The data from the questionnaire found that only 51 % of respondents over the age of 70 supplemented with...
