Pohořilský, Marek ; Mlkvik, Marek (referee) ; Lízal, František (advisor)
The bachelor thesis deals with optimization of artificial lung ventilation (CPAP) aiming to achieve higher efficiency in use with neonates at neonatal intensive care unit. The content of the thesis is divided into three parts. The first part describes the basic principle of the mechanical ventilation operation, lung parenchymal disease, respiratory care of neonates and patient interface devices. The second part of the thesis focuses on research, which is divided into chapters describing calculation of pressure loss and the experiment itself. The last part outlines a comparison and evaluation of individual interface devices and recommendation of effective practical use.

The effect of air pollution on oxidative stress markers in newborns
Ambrož, Antonín ; Rössner, Pavel (advisor) ; Rubeš, Jiří (referee) ; Gábelová, Alena (referee)
In everyday life, humans are exposed to toxic substances of anthropogenic origin. These substances can also be found in the ambient air and their impact poses a long-term risk for human health. Respirable particulate matter (PM) of aerodynamic diameter < 2.5 µm (PM2.5) is intensively studied, along with carcinogenic polycyclic aromatic hydrocarbons (PAHs), bound to it, such as benzo[a]pyrene (B[a]P), a reference carcinogenic PAH. Owing to small size, PM2.5 can penetrate the human body primarily via the airways and represent an increased health risk compared to larger particles. The negative health impacts of anthropogenic PM2.5, generated e.g. by fossil fuel combustion, are linked with its small size, relatively large surface, as well as with PAHs and other substances adsorbed on PM surface. PAHs, generated by an incomplete combustion of organic matter, can enter organism either via ingestion of contaminated food, water or via inhalation of polluted air. PAHs affect organisms via genotoxic, mutagenic, carcinogenic, embryotoxic and other adverse effects. One of the common denominators of these effects is oxidative stress, which is also considered to be the main mechanism of action caused by PM in the human organism. Oxidative damage induced by reactive oxygen species (ROS) may affect any cellular...

The study of mitochondrial energy-metabolism maturation
Křížová, Jana ; Hansíková, Hana (advisor) ; Pecina, Petr (referee) ; Rauchová, Hana (referee)
During intrauterine development in mammals, the fetus is exposed to a hypoxic environment. To allow proper postnatal adaptation to external conditions, a rapid transition from glycolytic to oxidative metabolism by mitochondria is required in fetal tissues after birth. Mitochondrial maturation is a complex process that is not only transcriptionally regulated. Using techniques such as microarray analysis, quantitative PCR, measurement of enzyme activities or coenzyme Q (CoQ) levels, we have described the acceleration of mitochondrial metabolism in rat liver tissue and skeletal muscle during the perinatal period and correlated the results with those in humans. Of the 1546 rat mitochondrial genes tested, we found statistically significant differences in the expression of 1119 in liver and 827 in muscle. The most significant shift in expression occurred in the rat liver between 20th and 22nd day of gestation, suggesting that the rat fetus is ready for the transition to external conditions at least 2 days before birth. Changes in CoQ levels in both rats and humans show that the amount of CoQ is low inthe prenatal period and increases after birth in both tissues. We have described the atypical kinase Coq8ap as an enzyme whose expression increases significantly after birth. It was previously predicted to...

Sepsis in newborne
Baláčková, Šárka ; Voxová, Barbora (advisor) ; Paterová, Pavla (referee)
Author: Šárka Baláčková Title: Septic states of newborns Bachelor thesis Charles University in Prague, Faculty of Pharmacy in Hradec Králové Field of study: medical laboratory technician Background: The aim of the work was to sample information on the issue of septic states of newborns, to describe laboratory diagnosis of examining neonatal sepsis. To map rate of the most common pathogens causing this illness in Masarykova hospital in Ústí nad Labem. Method: Tracking of sampled blood cultures at neonatal department between years 2011- 2015. Comparison of total amount of blood cultures with the amount of positive blood cultures and the rate of particular pathogens causing neonatal sepsis. Results: During the reporting period were collected a 5271 blood cultures to total count. 1047 of those were positive, making it 20 %. The most prominent causes of neonatal sepsis is above all coagulase-negative Staphylococcus with the count of 801 occurrences, which is 76,5 %. Followed by Gram-negative facultative anaerobic rods with 103 occurrences (10,8 %), Anaerobic bacteria with 48 counts (4,6 %), Enterococcus species with 31 counts (3%), Staphylococcus aureus with 26 counts (2,5 %), Streptococcus species with 21 counts (2 %) and Yeasts with 7 counts (0,7 %). Conclusions: Neonatal septic state is a serious...

Various Surgical Techniques of Lesional vas Deferens Repair in Rat Experiments
Štichhauer, Radek ; Kaška, Milan (advisor) ; Rygl, Michal (referee) ; Plánka, Ladislav (referee)
Various surgical techniques for the repair of injured vas deferens in rat experiment Introduction: The herniotomy for inguinal hernia is one of the most frequent surgical procedures in paediatric surgery. The incidence of complication following primary inguinal herniotomy in neonates is not rare and repair of the injured vas deferens (VD) is not standardized. The aim of this experimental study was to assess the contusion of VD during the surgery with a surgical instrument and to perform and consequently analyze some possibilities of a simple repair method under the control of operating loupe. Methods: Seventy male rats were divided into seven subgroups according to the type of the vas deferens injury and its repair consequently: 1. Contusion, 2. cut-off and a simple one layer vasovasostomy sewn by absorbable sewing material, 3. cut-off and joining by an intraluminally lead fibre of absorbable sewing material knotted externally, 4. = 3. using non- absorbable sewing material, 5. = 2. combine with intraluminally situated absorbable sewing fibre fixed externally,6. = 5. combine with intraluminally situated non-absorbable sewing fibre fixed externally, 7. = 5. without external fixation. Fibres of non-absorbable sewing material were removed 3 weeks after the first operation. Operated or injured parts of...

Assisted reproduction - influence on fertility and selected characteristics of newborns in Czechia
Martínková, Kateřina ; Šťastná, Anna (advisor) ; Kocourková, Jiřina (referee)
Assisted reproduction - influence on fertility and selected characteristics of newborns in Czechia Abstract The use of assisted reproductive technology (ART) has become very widespread in recent years, even in Czechia. The aim of this paper is to identify ART's influence on fertility rates and selected characteristics of newborns, especially in the context of demographics in Czechia. The first part of the thesis focuses on describing the process of fertility postponement and the related use of various ART methods. The second part deals with analyzing fertility level and timing and selected characteristics of newborns with emphasis on the comparison of children according to the method of conception. A data set is used for analysis, which was created by linking data on ART cycles from the National Register of Assisted Reproduction with data of children born collected by the Czech Statistical Office. A detailed analysis shows that the spread of assisted reproduction has a significant impact on the overall demographic situation in Czechia, especially in the ability of older women to realize their fertility. This analysis also suggests some differences between infants born via ART versus infants born without the use of ART in terms of birth outcomes. Binary logistic regression also confirms a certain effect of...

Breastfeeding in the COVID-19 era
Brožková, Adéla ; Laštůvka, Zdeněk (advisor) ; Černý, Andrej (referee)
Bachelor thesis is focused on breast-feeding and midwife competences and her irreplaceable care in life of nursing woman. Thesis is based as theory-practice work. Goal of theoretic part is to summary the knowledge of nursing with specific focus on COVID-19 disease and its disadvantage on nursing women. Practical part of the thesis is based on results from medical documentation of monitored homogenous group of woman, with added conclusions data from questionnaires addressed to this homogeneous group of woman. Thesis monitors differences in fully nursed newborns, partially nursed newborns with artificial nutrition on side and newborns fully nourished by artificial nutritious. Data were followed during leave from the maternity yard, after three months and after six months. Reported data were compared between control year 2019 and monitored year 2020, when world was flooded by COVID-19 disease which resulted in various limitations during hospitalisations. Thesis also examine bonding and its effect on nursing woman. Statistics methods fully supported first hypothesis, as no significant differences between nursing women leaving from hospital were reported in year 2021 versus control year 2019. Other two hypothesis were rejected, as statistical data showed that in third and sixth month after childbirth...
