Polívková, Sylvia ; Beneš, Jiří (advisor) ; Krbková, Lenka (referee) ; Rožnovský, Luděk (referee)
Introduction: Clostridioides difficile infection (CDI) is the most common nosocomial gastrointestinal infection, it is associated with antibiotic use and due to the spread of epidemic strains of C. difficile, there are differences in the course and severity of the disease. This study aimed to describe the characteristics of patients with CDI, to perform molecular analysis of isolates , and then to correlate CDI course and treatment outcomes with the causative ribotypes. Furthermore, the efficacy of antibiotic regimens in the treatment of CDI was evaluated with the severity and number of CDI episodes. Methods: The observational cohort study was conducted in 2013-2016 at the Department of Infectious Diseases of the Bulovka University Hospital in Prague. Patients with laboratory-confirmed CDI were included in the study. C. difficile isolates were characterized by ribotyping, multiple variable tandem repeat analysis (MLVA) and examination of antibiotic resistance determinants (mutations in gyrA, gyrB, rpoB genes or the presence of ermB). Univariate logistic regression was used to evaluate the efficacy of antibiotic regimens (metronidazole, vancomycin, combination of vancomycin and metronidazole, fidaxomicin). Subgroup analyses were performed based on the number and severity of CDI episodes. Results: A...

Perception of risk factors for atherosclerosis from the perspective of a patient after acute myocardial infarction
SAMCOVÁ, Tereza
This bachelor thesis focuses on examining the perception of atherosclerosis risk factors from the perspective of patients after acute myocardial infarction. The theoretical part delves into the characteristics of atherosclerosis and its associated risk factors. It also addresses myocardial infarction, including its pathophysiology, treatment procedures, and nursing care for patients post-MI.The practical part sets two main objectives. The first objective is to map the perception of atherosclerosis risk factors among patients post-MI, while the second objective is to assess whether these patients have changed their behavior regarding atherosclerosis risk factors. To achieve these goals, qualitative research in the form of semi-structured interviews was conducted with 13 patients who were at least one month post-MI. The research took place in a cardiology outpatient clinic in České Budějovice.The research indicates that the majority of patients are aware of atherosclerosis risk factors and strive to follow preventive measures. Additionally, it is evident that all patients post-MI have exhibited some degree of behavior change concerning atherosclerosis risk factors.These findings could serve as a basis for developing educational programs aimed at preventing atherosclerosis in patients post-MI, thereby contributing to the overall improvement of their health status and quality of life.

The diploma thesis deals with work categorization falling into the issue of occupational health protection. The theoretical part is devoted to current legislative reguirements of the EU, the Czech Republic and relevant standards. It also provides a general overview of the system of public health authorities together with a more detailed description of the work categorization topic and related concepts and requirements. This thesis has been made in cooperation with Varroc Lighting Systems, s.r.o., Nový Jičín. The practical part deals with the suggested change of categorization of the optimized assembly line work positions for car rear lighting (B479 OUTER RL). The main aim of this work is to check the correctness of the classification of individual work positions. The intention of updating the categorization is also to reduce the negative impact of critical risk factors of working conditions, which brings benefits for both employees and employers. The specific course of the classification of individual risk factors with a focus on the noise as a critical risk factor is demonstrated on the riskiest work position of the assembly line. In the end, the achieved results of updated classification of all positions are evaluated. The follow-up changes and the resulting benefits of updating the categorization, including other practical recommendations, are also summarized.

Analysis of Influence of Blood Flow and Arterial Geometry on Pathological Processes in Arteries
Jagoš, Jiří ; Rudolf, Pavel (referee) ; Jonášová,, Alena (referee) ; Burša, Jiří (advisor)
Se zvyšující se průměrnou délkou života a nezdravým životním stylem se velmi úzce pojí zvýšený výskyt kardiovaskulárních chorob. Většina z těchto nemocí je asymptomatických. Je zde tedy velká snaha rozpoznat tato onemocnění časně, dokud je možné je léčit konzervativně pomocí změny životního stylu či různých léků. Pokud se nemoc objeví až v pozdním stádiu, je nutná často velmi riziková operace. Stále se velmi často stává, že u pacienta v rizikové skupině se kardiovaskulární choroba nerozvine, a naopak u toho, který v rizikové skupině dle stávajících kritérií není, ano. Výpočtové modelování kardiovaskulárního systému je jedním z mnoha způsobů, které mohou pomoci se sofistikovanější indikací osob, u kterých je zvýšené riziko vývoje těchto chorob. V práci byly nejprve úspěšně validovány výsledky numerického modelu pulzujícího proudění v tuhé a elastické trubici skrze rychlostní profily. Podmínky experimentu byly záměrně voleny tak, aby byly blízké podmínkám v lidské aortě. Další část práce je věnována výběru a implementaci okrajových podmínek pro numerické modely pulzujícího proudění v lidských tepnách. První přístup pomocí určení rychlosti šíření pulzní vlny v tepně a následné časové korekci mezi vstupní a výstupní okrajovou podmínkou je poměrně jednoduchý, nicméně přímo předepisuje tvaru tlakové nebo průtokové vlny pro každý vstup a výstup z modelu a jeho prediktivní vlastnosti jsou tímto výrazně omezené. Jeho další nevýhodou je aplikovatelnost pouze pro simulace proudění, které uvažují poddajnost stěny. V případě simulace proudění s tuhou stěnou časovou korekci vstupní a výstupní okrajové podmínky nelze provést. Zde v práci byl tento přístup využitý v simulacích, které uvažují vzájemnou interakci stěny tepny s kapalinou, při prověřování potenciálního rizikového faktoru úhlu ilických tepen na rozvoj aneurysmatu abdominální aorty (AAA). Ukázalo se, že pro velký (ale stále fyziologický) rozsah úhlu ilických tepen nedochází ke zvýšení tlaku v aortě. Dále byl prověřen vliv poměru průřezů ilických tepen vůči průřezu aorty, u kterého se prokázal výrazný vliv na zvýšení tlaku v aortě. Výsledky jsou v souladu s klinickým pozorováním, které ukazují, že lidé po amputaci dolní končetiny, nebo lidé se stenózou v ilické tepně mají významně zvýšené riziko vzniku AAA. V závěrečné části byl zkoumán vliv tvaru průtokové vlny v lidské karotidě na vznik aterosklerózy. Bylo zrekonstruováno pět geometricky odlišných karotických bifurkací ze „zdravých“ starších pacientů. Reprezentativní vstupní okrajové podmínky průtoků pro staršího i mladého jedince byly převzaty z literatury. Výstupní okrajové podmínky pro interní a externí karotidu byly reprezentovány tří parametrickým Windkessel modelem. Parametry Windkessel modelu byly iteračním postupem odladěny tak, aby průběh průtokové vlny v interně byl v souladu s průběhem v literatuře. Tyto okrajové podmínky vystihují chování periferie velmi věrohodně. Navíc vykazují výrazně vyšší numerickou stabilitu a predikční vlastnosti než prvně zmíněný přístup. Analýzou výsledků bylo zjištěno že proudění v karotidě u zdravé starší osoby vykazuje výrazné snížení časově průměrovaného smykového napětí na stěně tepny vůči osobě mladé, což indikuje zvýšené riziko vzniku aterosklerózy. Výsledky jsou v souladu s klinickým pozorováním a rozšiřují dosavadní znalosti o mnohem hlubší analýzu. Je zde také diskutován případný přínos antihypertenziv a pravidelného cvičení.

Verification of the Predictive Relationship of Risk Factors on the Child Endangerment
Lipová, Dana ; Jeřábek, Hynek (advisor) ; Soukup, Petr (referee)
The thesis examines the relationship between factors that are considered risky in the area of social and legal protection of children, and the child endangerment, which is a legal reason for a state intervention in the family. The child endangerment was conceptualized based on the child trauma theory. Risk factors were identified by means of a comparative analysis of Czech and foreign instruments of social and legal child protection bodies. The MIMIC model was used to investigate the relationships between risk factors and the child endangerment, which enables comprehensive testing of relationships between several independent variables and one dependent latent variable, which is measured by a set of manifest variables, the model also works with mutual relationships between independent variables. The testing of the model proved that risk factors have a very different degree of influence on the child endangerment, and that it is important to take into account not only their direct influence, but also those mediated through other factors. The model proved that several factors have no influence on the child endangerment. It also follows from the model that it is sufficient to work only with a limited set of key factors when evaluating the child's situation.
