The effect of enriched blood plasma on the treatment of chronic wounds
Šíma, Petr ; Džupa, Valér (advisor) ; Rob, Filip (referee) ; Burda, Rastislav (referee)
Population ageing is connected with increased incidence of chronic diseases. Some of the frequent conditions are chronic skin defects which are not life threatening, however, they significantly impair the quality of patient's life. The aim of this study is to present and test new materials and procedures leading to improvement and acceleration of treatment of lower leg ulcers. The first part of the study is focused on experimental laboratory testing of the impact of platelet rich plasma on cell growth in the in-vitro conditions. The experiment comprised of combination of new materials made from nanofibers generated from various types of organic polymers. Bio-compatibility and bio-degradability of cell carriers intended for treatment of chronic defects and mechanical properties of materials were monitored. The second part of the study is focused on the proof of better healing of chronic defects if the platelet rich plasma is used locally. The cohort included 25 patients with chronic defects who were treated using the autologous growth factors applied on nanocarriers. The control group included 15 patients treated by a standard moist wound therapy. The surface area and depth of the defect was measured and the results were subsequently statistically processed and evaluated. The third part of the...

Epidemiological Analysis of Sexually Transmitted Infections in Czechia
Sekera, Jan Carlos ; Dzúrová, Dagmar (advisor) ; Pikhart, Hynek (referee) ; Rob, Filip (referee)
Sexually transmitted infections are among the diseases that are showing an increase and pose significant health problems, especially among the young population. They directly impact sexual reproductive health through stigma, infertility, cancer and pregnancy complications and can increase the risk of HIV. The dissertation focuses on the epidemiological situation of sexually transmitted infections in the Czech Republic. It seeks to supplement the missing data on this group of diseases and thus contribute by analysis to a better understanding of the development and current state in the Czech Republic. The work is conceived as a set of articles. Within the dissertation, the author introduces the context of his professional focus within the field of knowledge through published studies. The published studies that make up this dissertation focused on four critical areas of the issue of sexually transmitted infections: health literacy, socio-demographic analysis of injecting drug users, HIV testing at the time of the pandemic and regional differences The first set of included papers analysed HIV/AIDS health literacy levels. Knowledge of inequalities in health literacy is a crucial prerequisite for applying preventive measures. The second of the enrolled studies focused on analysing sexually transmitted...

Psoriasis is a chronic noninfectious and inflammatory skin disease, whose pathogenesis involves environmental triggers, including microbiota. In our study we compared bacterial composition between healthy controls and psoriatic patients using V1V2 hypervariable region of 16S rRNA. We found higher species diversity in psoriatic lesions than in contralateral psoriatic healthy site or in healthy control skin. Genus Propionibacterium was more abundant in contralateral healthy sites (57.77%) than in affected psoriatic sites of psoriatic patients (47.12%). On the other hand, we found higher abundance of genus Staphylococcus in psoriatic lesions (18.78%), while lower abundance in contralateral healthy sites (9.52%). Since Propionibacterium are commensal bacteria, the shift in their abundance from healthy to psoriatic skin could be due to disturbation of natural skin habitat. Interpretation of higher presence of Staphylococcus in psoriatic lesions comparing to contralateral healthy sites requires further species characterization. To complete the picture about psoriatic microbiome we will further investigate skin fungal composition in identical samples.

Anotace v anglickém jazyce\n\nMouse model of human psoriasis and gnotobiotic are important tools in understanding the role of gut and skin microbiota in pathogenesis of psoriasis. In our experiments we showed that gnotobiotic mice, as well as conventional mice treated with antibiotics, have milder skin inflammation in comparison with control conventional mice. Treatment with broad spectrum antibiotics led to dramatic shift in gut microbial composition, in particular, we observed extensive increase of order Lactobacillales. To analyze the potential effect of Lactobacillales on skin inflammation, we further monocolonized mice with L. plantarum WCFS1. Also monocolonized mice showed lower skin inflammation in comparison with conventional mice. To understand whether microbial dysbiosis is cause or effect of psoriasis needs to be further investigated.\n\n
