Study of placental specific microRNA expression in pacients with spontaneous preterm birth and preterm prelabor rupture of membranes
Vintrová, Iva ; Hromadníková, Ilona (advisor) ; Daňková, Pavlína (referee)
MicroRNAs (miRNAs) are small non-coding RNAs with a length of 18 to 25 nucleotides playing a pivotal role in post-transcriptional regulation of gene expression. There are miRNAs whose expression is limited to a certain tissue type and diseases which are characterized by a unique miRNA expression profile. I assumed spontaneous preterm birth (PTB) and preterm prelabor rupture of membranes (PPROM) would be characterized by a unique miRNA expression profile. I observed the gene expression of 15 placental specific miRNAs (miR-512-5p, miR-515-5p, miR-516b-5p, miR-517-5p, miR-518b, miR-518f-5p, miR-519a-5p, miR-519d-3p, miR-519e- 5p, miR-520a-5p, miR-520h, miR-524-5p, miR-525-5p, miR-526a and miR-526b-5p) in placental tissue of pacients with PTB, PPROM and women with term in labor pregnancies (FG). PTB group consisted of 24 pacients, PPROM group of 75 pacients and FG group of 20 pacients. Quantitative real-time PCR was used to quantify gene expression. In the group of PTB pregnancies I identified 3 significantly upregulated miRNAs (miR-516b-5p, miR-519d-3p and miR-524-5p) and 4 miRNAs (miR-518b, miR-519a-5p, miR-520h and miR-526a) with a trend to upregulation compared to controls (FG). In the group of PPROM pregnancies I identified 3 miRNAs (miR-519d-3p, miR-520h and miR-256b-5p) with a trend to...

Obstetric situations in prehospital emergency care and duties of a medical rescuer
KLEČATSKÁ, Lucie
The paper treats the subject of obstetric situations in pre-hospital emergency care and the tasks tackled by paramedics. Vital in such situations are the early recognition of symptoms; correct diagnostics; and a speedy transfer of the patient to a hospital. The paper concentrates primarily on delivery during the pre-hospital emergency care; on premature leak of the amniotic fluid; and on bleeding encountered in pregnant women in the second half of gestation and the related complications. The effort aimed particularly at mapping the frequency of emergency obstetric situations met during the pre-hospital emergency care in the Region of South Bohemia; at exploring the experience of paramedics; and at finding whether they were afraid of such situations and whether they were able to apply their theoretical background in practice. The defined objectives yielded four hypotheses: H 1: Emergency obstetric situations emerging during the transit are rare in the South Bohemian Region; H 2: Paramedics possess sufficient theoretical erudition to manage the emergency obstetric situations; H 3: Paramedics do not possess sufficient theoretical erudition to manage the emergency obstetric situations; and H 4: In providing emergency pre-hospital care paramedics try mainly to take the patient to hospital in good time. The research section of the paper relied on a quantitative survey conducted through a questionnaire distributed among paramedics in the Region of South Bohemia. Altogether 80 questionnaires were distributed, out of which 66 constituted the surveyed set. The results were processed and assembled into cake diagrams best depicting the percentage shares. All objectives have been accomplished. The first and fourth hypotheses proved false, while the second and third proved true.
