Background: The clinical importance of assessing the fetal KEL genotype is to exclude ‘K'-positive fetuses (genotype KEL1/KEL2) in ‘K'-alloimmunized pregnant women (genotype KEL2/KEL2). Noninvasive assessment of the fetal KEL genotype is not yet available in the Czech Republic. Objective: The aim of this study was to assess the fetal KEL1/KEL2 genotype from cell-free fetal DNA in the plasma of KEL2/KEL2 pregnant women. Methods: The fetal genotype was assessed by minisequencing (a dilution series including control samples). A total of 138 pregnant women (between the 8th and 23rd gestational week) were tested by minisequencing. The fetal genotype was further verified by analysis of a buccal swab from the newborn. Results: Minisequencing proved to be a reliable method. In 2.2% (3/138) of the examined women, plasma sample testing failed; 94.8% (128/135) had the KEL2/KEL2 genotype, and a total of 3.1% of fetuses (4/128) had the KEL1/KEL2 genotype. Sensitivity and specificity reached 100% (p < 0.0001). Conclusion: Minisequencing is a reliable method for the assessment of the fetal KEL1 allele from the plasma of KEL2/KEL2 pregnant women.

Introduction/Aim. Induced termination of unwanted pregnancy after 12th gestational week (late-term abortion) is legally restricted in Serbia as well as in many other countries. On the other hand, unwanted pregnancy very often brings women into the state of personal crisis. Psychiatric indications for legally approved late-term abortion on women?s demand include only severe psychiatric disorders. The aim of this paper was to compare sociodemographic, psychological characteristics and claimed reasons for abortion in the two groups of women with late-term demand for abortion - the group of women satisfying legally prescribed mental health indications, and the group of women not satisfying these indications. The aim of the study was also to determine predictive validity of the abovementioned parameters for late-term abortion as the outcome of unwanted pregnancy. Methods. A total of 62 pregnant women with demand for late-term abortion were divided into two groups according to the criteria of satisfying or not satisfying legally proposed psychiatric indications for late-term abortion after psychiatric evaluation. For the assessment of sociodemographic and psychological parameters sociodemographic questionnaire and symptom checklist - 90 revised (SCL-90?) scale were used, respectively. The outcome of unwanted pregnancy was followed 6 months after the initial assessment. Results. The obtained results showed a statistically significant difference between the groups in educational level, satisfaction with financial situation, elevated anxiety and distress reactions. Unfavorable social circumstances were the main reason for an abortion in both groups and were predictive for an abortion. A 6-month follow-up showed that women had abortion despite legal restrictions. Conclusion. Pregnant women with psychiatric indication for late-term abortion belong to lower socioeconomic and educational level group compared to women without this indication who have more frequently elevated anxiety and distress reactions to unwanted pregnancy. It is necessary to have more accurate guidelines for mental health indications for legally approved late-term abortion, respecting social circumstances. Preventive measures are of great importance in order to lower the risk of illegally performed late-term abortions.

Abstract Introduction Evening chronotype is associated with greater reports of insufficient sleep and sleep-related distress. Little research has examined this relationship within the context of pregnancy. This study investigated whether eveningness predicts insomnia severity, sleep effort, dysfunctional sleep beliefs, and sleep reactivity to stress in pregnant women with insomnia disorder. Methods Pregnant women with insomnia disorder who spoke English or Spanish enrolled in a clinical trial of cognitive behavioral therapy for insomnia (N = 178; M age = 32.6 years). Before beginning treatment, participants completed the Composite Scale of Morningness (CSM), Insomnia Severity Index (ISI), Glasgow Sleep Effort Scale (GSS), Dysfunctional Beliefs and Attitudes about Stress Scale (DBAS), and Ford Insomnia Response to Stress Test (FIRST). Participants were categorized into evening, intermediate, or morning chronotypes (bottom 25%, middle 50%, or top 25% of CSM scores, respectively). MANCOVA examined whether chronotype predicted higher baseline ISI, GSS, DBAS, and FIRST scores after adjusting for age, gestational week of pregnancy, and language. Results Sleep measures collectively differed by chronotype, F(8, 336) = 4.05, p &lt; .001; Wilk’s Λ = .83, partial η-sqd = .09. Follow-up ANOVAs testing individual dependent variables were all significant (partial η-sqd = .04 – .10, p &lt; .05). Pairwise comparisons (Bonferroni-adjusted; p &lt; .05) found that evening types had higher ISI scores than intermediate (M difference = 2.21) and morning types (M difference = 2.30), and higher DBAS scores than morning types (M difference = .95). Morning types had lower FIRST scores than evening (M difference = 5.44) and intermediate types (M difference = 3.89). Conclusion Evening chronotype was associated with greater insomnia severity and maladaptive sleep-related cognition than other chronotypes among pregnant women with insomnia disorder. Future research may examine whether differences in chronotype have implications for insomnia treatment outcome during pregnancy, and whether greater morningness confers protection against sleep challenges during the early postpartum period.

The aim of this work was to suggest a reliable method for distinguishing between diploid and tetraploid taxa of the genus Betula Linnaeus, based on leaf measurements. In total, 97 individuals from 6 locations within the Bohemian Forest region (Czech Republic) were selected. Four leaves from each individual were evaluated. On each leaf, twenty parameters were measured. Each sample was analysed by flow cytometry to determine its actual ploidy. Measured parameters were analysed by principal component analysis and tested for differences between diploid and tetraploid taxa. For actual ploidy prediction, a classification function was designed. The reliability of the classification function was verified on samples from three different regions of the Czech Republic and compared with functions as suggested by other authors. The classification function designed in this work (based on 3 parameters – blade width in the upper 1/4 of blade length, first vein angle and number of leaf teeth between 3<sup>rd</sup> and 4<sup>th</sup> vein) correctly determined actual ploidy in 89% of all tested samples.

Noninvasive fetal RHD genotyping is an important tool for predicting RhD incompatibility between a pregnant woman and a fetus. This study aimed to assess a methodological approach other than the commonly used one for noninvasive fetal RHD genotyping on a representative set of RhD-negative pregnant women. The methodology must be accurate, reliable, and broadly available for implementation into routine clinical practice. A total of 337 RhD-negative pregnant women from the Czech Republic region were tested in this study. The fetal RHD genotype was assessed using two methods: real-time PCR and endpoint quantitative fluorescent (QF) PCR. We used exon-7-specific primers from the RHD gene, along with internal controls. Plasma samples were analyzed and measured in four/two parallel reactions to determine the accuracy of the RHD genotyping. The RHD genotype was verified using DNA analysis from a newborn buccal swab. Both methods showed an excellent ability to predict the RHD genotype. Real-time PCR achieved its greatest accuracy of 98.6% (97.1% sensitivity and 100% specificity (95% CI)) if all four PCRs were positive/negative. The QF PCR method also achieved its greatest accuracy of 99.4% (100% sensitivity and 98.6% specificity (95% CI)) if all the measurements were positive/negative. Both real-time PCR and QF PCR were reliable methods for precisely assessing the fetal RHD allele from the plasma of RhD-negative pregnant women.

Introduction. The aim of the present study was to examine placental levels of DUSP9 mRNA and protein and to investigate the potential role of DUSP9 in the development of gestational diabetes mellitus (GDM). Methods. Placental tissues from pregnant women with GDM (n=17) and normal healthy pregnant women (n=16) were collected at delivery. The expression of DUSP9 mRNA in placental tissue was analyzed by real-time PCR, while the expression of DUPS9 protein was evaluated by immunohistochemistry and western blot. Differences in the expression levels of DUSP9 mRNA and protein between the two groups were assessed, as well as potential correlations between DUSP9 mRNA expression levels and relevant clinical indicators. Results. Blood glucose levels were significantly higher in the GDM group than in the control group, based on an oral glucose tolerance test. DUSP9 protein was expressed in the placental cytotrophoblasts in both groups, and placental levels of DUSP9 protein and mRNA were significantly higher in women with GDM. Placental DUSP9 mRNA levels in all 33 women correlated moderately with delivery gestational week (R=0.465, P=0.006), fasting plasma glucose (R=0.350, P=0.046), 1-hour postload plasma glucose (R=0.363, P = 0.038), and 2-hour postload plasma glucose (R=0.366, P=0.036), but not with maternal age, preconception body mass index, prenatal body mass index, or neonatal birth weight. Multiple linear regression analysis indicated that delivery gestational week was an influence factor of DUSP9 mRNA levels (β1=0.026, P<0.05). Conclusions. DUSP9 upregulation in the placenta of GDM pregnant women may promote insulin resistance, which may correlate with the occurrence of GDM. But there is still possibility that DUSP9 upregulation was the results of insulin resistance and/or hyperglycemia. Further research is needed to explore the role of DUSP9 in GDM.

ObjectivesPre-eclampsia (PE) is characterised by renal glomerular endotheliosis and injury to the glomerular filtration barrier with proteinuria. Patients with PE display aberrant filtration of the plasma proenzyme plasminogen which is activated, in the tubular fluid, to plasmin. Plasmin may activate the epithelial sodium channel and cause impaired sodium excretion and contribute to hypertension. An explorative study was conducted to test the association between urinary total plasminogen/plasmin and the development of PE. A positive association was hypothesised.DesignAn observational, explorative, nested case–control study of healthy pregnant women.SettingsA Danish County hospital. Samples were collected between 2001 and 2004.Participants1631 healthy pregnant women participated. Urine samples were collected longitudinally six times during pregnancy. 30 developed PE (cases) and were compared with 146 randomly selected healthy pregnant women (controls).Primary outcomeThe association between total plasminogen/plasmin excreted in the urine and PE development is expressed by ORs. Total urinary excretion of plasminogen/plasmin was defined by the urine plasminogen-plasmin/creatinine ratio.Secondary outcomeThe association between urine (u)-albumin/creatinine ratio, u-aldosterone/creatinine ratio and PE development is expressed by ORs. The correlation between urinary (u-) plasmin and u-aldosterone concentration is expressed as a correlation coefficient.ResultsThe development of PE in late pregnancy was associated with increased levels of the urine plasminogen-plasmin/creatinine ratio (OR=2.35; 95% CI: 1.12 to 4.93; p<0.05).U-aldosterone/creatinine ratio did not predict PE at any time. U-albumin/creatinine ratio was positively associated with the development of PE from gestational week 33 (OR=14.04; 95% CI: 2.56 to 76.97; p<0.01) and in week 33–35 (OR=14.15; 95% CI: 3.44 to 58.09; p<0.001) and after gestational week 36, respectively.ConclusionAberrant filtration of plasminogen may contribute to the pathophysiological features of impaired sodium excretion and hypertension associated with PE late in pregnancy. However, increased urinary albumin levels reveal stronger associations with PE development compared with urinary plasminogen levels.
