Registration of a pregnant woman in the maternity hospital (optimally at 36th-37th weeks) at the Olomouc University Hospital in 2022.

OBJECTIVE: The aim of the study was to analyse the results of the implementation of the new health service Registration of a pregnant woman in the maternity hospital (optimally at 36th-37th weeks) provided as part of outpatient/ambulatory health care at Olomouc University Hospital (OUH). MATERIALS AND METHODS: A prospective cohort study. In 2022, a total of 2,271 women gave birth in OUH, and 2,010 of them were Registered in the maternity hospital, defined specific risks were identified and a pregnancy termination strategy was established/determined. RESULTS: The health service was provided to 88.5% of women giving birth (2,010/2,271). The age of the mothers was 15-56 years (mean 31.3 years; median 31 years), their body mass index was 13.4-53.1 kg/m2 (mean 24.6 kg/m2; median 23.2 kg/m2). 43.6% of them (877/2,010) were Low-risk pregnancies and 56.4% (1,133/2,010) were Pregnancies with a defined specific risk. The most frequently identified risks were as follows: RhD negative blood group (18.4%), diabetes mellitus (13.9%), history of caesarean section (12.0%), hypertensive disorders (6.5%), small fetus/fetal growth restriction (6.3%), risk the development of hemolytic disease in the fetus and the newborn (2.5%), multiple pregnancy (1.6%), congenital malformation of the fetus (1.3%) and placentation disorders (0.5%). In 63.4% of them (1,275/2,010), the pregnancy termination strategy was determined by spontaneous vaginal delivery, in 18.0% (361/2,010) by pre-induction of vaginal delivery and in 14.2% (285/2,010) by caesarean section. In 4.4% (89/2,010) the health service was not implemented correctly because no strategy was established. CONCLUSION: The implementation of the new health service will make it possible to replace activity (more frequent antenatal care contacts/visits and routine antenatal cardiotocography) with efficiency (risk identification, determination of the optimal strategy for outpatient/ambulatory antenatal care and timing and mode of delivery) and thereby provide better and safer health care (from a medical, organizational, legislative and economic points of view).

Medical Termination of Pregnancy (MToP) in the 1st trimester - the role of human chorionic gonadotropin and ultrasound in pregnancy diagnosis and MToP follow-up.

OBJECTIVE: In the Czech Republic, it is possible, to carry out Medical Termination of Pregnancy (MToP) in the 1st trimester up until the 49th day of secondary amenorrhea. The aim of the study is to analyse the significance of serum/urine human chorionic gonadotropin (hCG) assessment and ultrasound (US) examination in pregnancy diagnosis and MToP follow-up. METHODS: In 2017-2018, MToP was carried out in a total of 109 women by administering a combination of mifepristone (600 mg orally) and misoprostol (400 mcg orally). Serum/urine (LSUP - low sensitivity urine pregnancy test) hCG assessment and US examination were performed at pregnancy diagnosis and MToP follow-up. RESULTS: At pregnancy diagnosis, there was a positive and medium strong correlation between serum hCG and size of the gestational sac - GS (R = 0.711; P  1,000 IU/L and LSUP test was always positive). In 5.5% of women (6/109), a subsequent surgical intervention was carried out including those with ongoing pregnancy (N = 5); missed abortion (N = 1) was treated by additional misoprostol, where surgical intervention was not necessary. CONCLUSION: At pregnancy diagnosis, there is a positive and medium strong correlation between serum hCG and CRL. In MToP follow-up, a negative LSUP test enables reliable exclusion of ongoing pregnancy and missed abortion. In case of a positive LSUP test, US examination should be performed; however, surgical intervention should not be indicated solely on the basis of uterine cavity dilatation.

Screening for congenital defects and genetic diseases of the fetus at University Hospital in Olomouc and sending/ reporting to the National register of reproductive health in the Czech Republic.

OBJECTIVE: The aim of the study was to analyze the results of the screening for congenital defects (CD) and genetic diseases (GD) of the fetus in the Fetal Medicine Centre at the Department of Obstetrics and Gynecology, University Hospital in Olomouc. MATERIALS AND METHODS: Prospective cohort study. In the period from 1 January 2020 to 31 December 2021, a total of 14,460 health services were performed on 4,916 pregnant women. Within the screening of CD and GD of the fetus, 501 pregnant women were found to have an abnormality requiring further clinical management, 170 of them were diagnosed with a CD of the fetus and in 20 cases a GD of the fetus was diagnosed by a laboratory genetic examination. All diagnosed fetal CD and GD were sent/ reported according to the valid methodology of the National health information system (NHIS) to the National register of reproductive health (NRRH) to the CD Module. RESULTS: An increased calculated individual risk of genetic fetal disease was diagnosed in the first trimester of pregnancy in 10.7% of fetuses (319/ 2,968), and in the second trimester in 0.9% of fetuses (27/ 2,948). Nuchal translucency (NT) > 3.5 mm was diagnosed in 0.9% of fetuses by ultrasound examination in the first trimester of pregnancy (26/ 2,968). In fetal CD and GD screening, 501 pregnant women were found to have an abnormality requiring further clinical management, 72.1% of women (361/ 501) had an increased risk of genetic fetal disease, and diagnostic examination of the fetal genetic material obtained by invasive procedure (chorionic villus sampling or amniocentesis) was indicated. A total of 31.3% of them (113/ 361) refused the invasive procedure and 2.5% (9/ 361) did not attend the planned procedure; the invasive procedure was performed in 66.2% (239/ 361). CONCLUSION: Comparing the results of CD and GD fetal screening in our medical facility with other specialized medical facilities in the Czech Republic is currently difficult to do, but information from the NRRH could allow objective and transparent comparisons in the future.

Should 3D volume assessment of the corpus callosum and cerebellar vermis be a part of a routine second trimester screening?

BACKGROUND: The majority of fetal structural defects can be detected in the second trimester, thus this is the main time for screening for structural defects. 3D imaging of the fetal brain does not create a common part of this screening. METHODS: This prospective observational study was conducted at the Fetal Medicine Center of The Gynecological-Obstetrical Department of the University Hospital Olomouc in years 2017-2020. The study sample was 451 consecutively scanned morphologically normal fetuses attending for routine second trimester anatomical survey at 20-22 weeks of pregnancy. A transabdominal 3D ultrasound volume acquisition of fetal brain was obtained from an axial and sagittal plane using skull sutures as an acoustic window. RESULTS: Both the corpus callosum (CC) and the vermis (VC) were detected in 51.7% of examinations in the sagittal plane, and in 31.7% in the axial plane. In 61.9% of the examinations, there was at least partial detection in both planes. Maternal BMI was found to be the only significant predictor of the quality of imaging in both planes. CONCLUSION: 3D acquisition of fetal brain images in the sagittal plane followed by manipulation of acquired volume was valuable in assessment of corpus callosum and cerebellar vermis. This allows reconstruction of the sagittal plane that can be difficult to obtain in 2D imaging.
