To identify and compare the time dynamics of artificial abortions in two (Czech and Slovak) ethnically, historically and socially closely related populations. Data have been taken separately for 12-15 and 16-18 year age girls from official exhaustive statistical sources and processed by advanced procedures of time series analysis. Czech and Slovak Republics. All girls of the given age. Legislative liberalization of abortions 1987. Estimated starting values of relative numbers of abortions by 1971, increasing linear trends, period lengths of fluctuation, coefficients of determination and those of cross-correlation. Level of significance alpha = 0.05. The Czech figures are significantly higher than the Slovak. Thus, estimated abortion percentage (from pregnancies) for 1971 was for younger Czech girls 53%, and for those from Slovakia 29%. All estimated trends were increasing significantly in all cases for the Czech population (by 1.5% per year in the younger group) and in one case for Slovakia. The estimated period lengths were usually 10-12 years. Czech and Slovak data display significant positive mutual cross-correlation, the delay being 1-3 years in Slovak girls. Surprisingly, all data significantly cross-correlate with the geomagnetic index value Ap, acting as lead-lag, with 3-6-year delay for abortions. Despite living in the same federal state--the former Czechoslovak Republic, both Czech and Slovak populations do differ in starting values and general trends of abortions in teenagers. This can be due to historical, racial and religious peculiarities as well as a more advanced process of industrialization in the western part--the Czech Republic. The latter hypothesis is corroborated by strong dynamism of changes and by the time delay in Slovakia. The periodicity exhibits a frequency resembling that known for solar motion round barycenter of solar system, for sunspots and geomagnetism.

The aims of this study were to evaluate seroprevalence and the importance of various risk-factors for Toxoplasma infection in the Czech Republic. A prospective cross-sectional survey was conducted among military personnel in Prague. Consenting subjects (n = 3250) completed a questionnaire concerning demographics and risk-factors, and blood samples were taken to determine anti-Toxoplasma antibody titres according to complement fixation and ELISA IgG and IgM tests. The seroprevalence of toxoplasmosis was 23%. In multivariate analysis, independent predictors of Toxoplasma seropositivity were age (OR 1.03 / year), consumption of raw meat (OR 1.35), owning a cat (OR 1.25), owning rabbits (OR 1.47), childhood residence in a town with a population of <10 000 inhabitants (OR 1.63) vs. location of the childhood residence in a town with population of >100 000 inhabitants, and blood group type A (OR 1.28), B (OR 1.33) or AB (OR 1.43) vs. O. These results suggested that horizontal toxoplasmosis transmission in the Czech Republic may occur through consumption of raw meat, contact with cat faeces and farming.

We have estimated the number of serious fungal infections in the Czech Republic. All published epidemiology papers reporting Czech fungal infection rates were identified. Where no data existed, we used specific populations at risk and fungal infection frequencies in those populations. Population statistics were obtained from the 2011 Census data, prevalence and incidence data for at-risk conditions were obtained from publicly accessible healthcare statistics and relevant surveys. We estimate that 152,840 Czech women suffer with recurrent vaginal thrush. Allergic bronchopulmonary aspergillosis is likely in 4739 adults and 6581 more have severe asthma with fungal sensitisation. Hypersensitivity pneumonitits secondary to fungi is estimated in 1050 cases and 365 people may have chronic pulmonary aspergillosis. Oesophageal candidiasis is estimated in 210 HIV-positive people. There are 12 cases of Pneumocystis pneumonia in HIV population and 60 more cases in non-HIV population. There are an estimated 526 cases of candidaemia, 79 cases of Candida peritonitis and 297 cases of invasive aspergillosis a year. About 176,000 (1.67%) Czech people suffer from severe fungal infections each year, predominantly from recurrent vaginitis and allergic respiratory conditions. Substantial uncertainty surrounds these estimates except for invasive aspergillosis in haematology and candidaemia in critical care. © 2015 Blackwell Verlag GmbH.

This is one of the first studies, which compares the level of stigmatizing behaviour in countries that used to be on the opposite sides of the Iron Curtain. The aim was to identify the prevalence of reported and intended stigmatizing behaviour towards those with mental health problems in the Czech Republic and to compare these findings with the findings from England. The 8-item Reported and Intended Behaviour Scale (RIBS) was used to assess stigmatising behaviour among a representative sample of the Czech population (n=1797). Results were compared with the findings of an analogous survey from England (n=1720), which also used the RIBS. The extent of reported behaviour (i.e., past and present experiences with those with mental health problems) was lower in the Czech Republic than in England. While 12.7% of Czechs reported that they lived, 12.9% that they worked, and 15.3% that they were acquainted with someone who had mental health problems, the respective numbers for England were 18.5%, 26.3% and 32.5% (P<0.001 in each of these items). On the other hand, the extent of intended stigmatizing behaviour towards those with mental health problems is considerably higher in the Czech Republic. Out of maximum 20 points attached to possible responses to the RIBS items 5-8, Czechs had a lower total score (x=11.0, SD=4.0) compared to English respondents (x=16.1, SD=3.6), indicating lower willingness to accept a person with mental health problems (P<0.001). The prevalence of stigmatizing behaviour in the Czech Republic is worrying. Both, further research and evidence based anti-stigma interventions, should be pursued in order to better understand and decrease stigmatizing behaviour in the Czech Republic and possibly across the post-communist countries in Central and Eastern Europe.

2016-01-01

Background: Differences in dietary habits have been suggested as an important reason for the large health gap between Eastern and Western European populations. Few studies have compared individual-level nutritional data directly between the two regions. This study addresses this hypothesis by comparing food, drink and nutrient intakes in four large population samples. Methods: Czech, Polish and Russian participants of the Health, Alcohol and Psychosocial Factors in Eastern Europe (HAPIEE) study, and British participants in the Whitehall II study, altogether 29 972 individuals aged 45–73 years, were surveyed in 2002–2005. Dietary data were collected by customised food frequency questionnaires. Reported food, drink and nutrient intake data were harmonised and compared between cohorts using multivariable adjusted quantile regression models. Results: Median fruit and vegetable intakes were lower in the pooled Eastern European sample, but not in all country cohorts, compared with British subjects. Median daily consumption of fruits were 275, 213, 130 and 256 g in the Czech, Polish, Russian and Whitehall II cohort, respectively. The respective median daily intakes of vegetables were 185, 197, 292 and 246 g. Median intakes of animal fat foods and saturated fat, total fat and cholesterol nutrients were significantly higher in the Czech, Polish and Russian cohorts compared with the British; for example, median daily intakes of saturated fatty acids were 31.3, 32.5, 29.2 and 25.4 g, respectively. Conclusion: Our findings suggest that there are important differences in dietary habits between and within Eastern and Western European populations which may have contributed to the health gap between the two regions.

Objective measured trend data are important for public health practice. However, these data are rare for an adult population. Therefore, the aim of this study was to describe time trends in pedometer-determined physical activity of Czech adults (25–65 years) from 2008 to 2013. Participants were Czech national citizens whose physical activity was assessed objectively using a Yamax Digiwalker SW-700 pedometer (Yamax Corporation, Tokyo, Japan) for seven consecutive days in the period 2008 to 2013. The final sample was 4647 Czech adults [M age 41.4 ± 10 years; M body mass index (BMI) 25.1 ± 3.7 kg/m2]. The results showed that men took more steps/day (M (Mean) = 10,014; 95% CI (Confidence Interval) = 9864–10,164) than women (M = 9448; 95% CI = 9322–9673) in all age and BMI groups. Mean steps/day declined from 2008 to 2013 by 852 steps/day in men and 1491 steps/day in women. In the whole sample, the proportion of participants who had a sedentary lifestyle (<5000 steps/day) increased by 5.8%; the proportion taking ≥10,000 steps/day decreased by 15.8%. In 2013, men and women were 2.67 and 2.05 times, respectively, more likely to have a physically inactive lifestyle (<7500 steps/day) than in 2008. Conversely, in 2008, men and women were 1.68 and 2.46 times, respectively, less likely to have very active lifestyle (>12,500 steps/day). In conclusion, this study suggests that there has been a substantial reduction in physical activity in Czech adults over time. PMID:27783062

The purpose of our study was to determine the content of trans fatty acids in early human breast milk as an indicator of dietary exposure in a sample of Roma breast-feeding women and in a sample of women from the general Czech population. We collected samples of early human milk from 43 Prague women from the general population and 21 Roma women. After lipid extraction, the fatty acids were converted into methyl esters (FAMEs). Finally, gas chromatography with flame ionization detector (GC-FID) analysis on a CP-Sil 88 column was used to determine C18:1 trans monoenic fatty acid levels and total trans isomers fatty acid levels in human milk. A significantly higher content of C18:1 trans fatty acid isomers was detected in human milk fat from Roma mothers than in women of the general population (2.73 vs. 2.09%, p < 0.05). Both groups monitored did not differ in the representation of total fatty acid trans isomers. Differences in the frequency of consumption of certain TFA sources (butter, fried crisps) were established. The study proved a higher fatty acid trans isomers content in Roma breast-feeding mothers in the Czech Republic, and this is probably related to their bad eating habits. (c) 2007 S.

We propose the first comprehensive in-depth study monitoring horses in the Czech Republic. We scanned 9,289 animals from 44 populations for 17 equine STRs. Other equids analysed involved Equus przewalskii and Equus asinus. The total of 228 different alleles were detected, with the mean number of 13.4 per locus. The highest allelic richness (AR) was found in the Welsh Part Bred (6.01), followed by the Camargue (5.93) and Czech Sport Pony (5.91), whereas the Friesian exhibited the lowest AR (3.06). Interpopulation differences explained approximately nine per cent of the total genetic diversity. Reynold's genetic distance ranged from 0.003 between the Czech Warmblood and the Slovak Warmblood to 0.404 between the Friesian and donkeys. Close genetic proximity between the Silesian Noriker and Noriker was revealed. The Moravian Warmblood was better differentiated and more distant from the Czech Warmblood than the Kinsky Horse and retained the original genes of the old Austro-Hungarian tribes. A high gene flow level and a lack of genetic structure were found in the seven studied populations. Despite the historical bottlenecks and previous inbreeding, the Czech-Moravian Belgian Horse, Hucul, Old Kladruber Horse and Silesian Noriker did not suffer a serious loss of genetic diversity due to genetic drift/low effective population size. A NeighborNet dendrogram revealed breeds not classified in their groups according to the nomenclature (the Friesian, Hafling and Merens). © 2018 Blackwell Verlag GmbH.

In recent years, the laparoscopic approach in oncologic urology seems more attractable to the surgeons. It is considered to have the same oncologic quality as open surgery, but is less invasive in patients. It is used widely in all of Europe, but with various frequency. The aim of the study was to present a various amount of oncourological procedures from three neighbouring countries - Poland, Czech Republic and Hungary. Prostatectomy, cystectomy, nephrectomy and tumorectomy (Nephron Sparing Procedures - NSS) were presented as a list of procedures prepared from the national registry. The total amount of procedures was presented, as well as the LO (Lap to Open procedures) index, P/P (procedures/population) index, ratio of cystectomy/population, and cystectomy/TURBT. In the Czech Republic, the most complex procedures are performed (laparoscopic/robotic prostatectomy, NSS LAP, LAP nephrectomy) in the majority when analysing the country's population. In Hungary and Czech Republic, there are more laparoscopic/robotic radical prostatectomies performed, than open ones. In Poland the largest number of cystectomies is performed when analysing the country's population, but it is difficult to explain the much higher ratio of 6.57 TUR/one cystectomy. In the Czech Republic this procedure is performed in almost one quarter of the patients (23.36%). Interestingly, in Hungary the cystectomy with pouch creation is performed in about 67.65% cases. The highest reimbursement for surgical procedure is present in the Czech Republic with approximately 20-40% more than when compared to Poland or Hungary. The definitive leader in Central Europe (based on the national registry) is the Czech Republic, where the most complex procedures are performed (laparoscopic/robotic prostatectomy, NSS LAP, LAP nephrectomy) in biggest amounts when analysing the country's population. Explanation of such circumstances, can be the higher reimbursement rate for surgical procedure in this country.

Association between unemployment, income, education level, population size and air pollution in Czech cities: evidence for environmental inequality? A pilot national scale analysis.

PubMed

Branis, Martin; Linhartova, Martina

2012-09-01

We analyzed differentials in exposure to SO(2), PM(10) and NO(2) among Czech urban populations categorized according to education level, unemployment rate, population size and average annual salary. Altogether 39 cities were included in the analysis. The principal component analysis revealed two factors explaining 72.8% of the data variability. The first factor explaining 44.7% of the data variability included SO(2), PM(10), low education level and high unemployment, documenting that inhabitants with unfavorable socioeconomic status mainly reside in smaller cities with higher concentration levels of combustion-related air pollutants. The second factor explaining 28.1% of the data variability included NO(2), high salary, high education level and large population, suggesting that large cities with residents with higher socioeconomic status are exposed to higher levels of traffic-related air pollution. We conclude that, after more than a decade of free-market economy, the Czech Republic, a former Soviet satellite with a centrally planned economy, displays signs of a certain kind of environmental inequality, since environmental hazards are unevenly distributed among the Czech urban populations.

The Czech Society for Oncology of the Czech Medical Association of J. E. Purkyně (ČOS ČLS JEP) builds on intensive collaboration at all levels of medical care during the organisation of oncological care. Over 77,000 malignant neoplasms are diagnosed in the Czech Republic annually. Every year, over 27,000 patients with a malignant tumour die in the Czech Republic. A total of over 450,000 patients with malignant tumours or patients with a history of an oncological disease are living in the Czech Republic. The specialised society analyses available data about the treatment history and offers them to the individual regions; it also plans population based treatment costs which are then discussed with the healthcare payers. The Czech National Cancer Control Programme (NOP) presents a strategic outline for the management and development of the treatment, and facilitates the communication with all stakeholders and the public. The ČOS ČLS JEP Society includes a specialised section responsible for data analysis, which provides a complex agenda of population based data, estimated numbers of treated patients, standards for reference of survival analysis and a system of collecting required clinical data. Even with a growing incidence, the Czech Republic shows a stabilised mortality in all cancer diagnoses. Screening programmes for breast, colorectal and cervical carcinoma are ongoing. We have a consolidated and cooperating network of oncology centres. We are able to actively plan diagnostic and treatment needs and we have a system of data collection that is able to respond to the needs of evaluation of cost efficiency. We are currently introducing a hospital care quality assessment.

In the Czech Republic, patients with diabetes mellitus (DM) are followed and treated predominantly by specialists (approx. 80% at a specialist diabetology clinic), a minor part by general practitioners (up to 20%). Long-term development of the changes in prescribing metformin and sulfonylurea in the Czech Republic and its concordance with recommended procedures has not been evaluated until now. Comparison of the development of metformin (MET) and sulfonylurea (SU) prescriptions in the period of 2002-2006 with that of 2010-2014 in a representative sample of the patient population with DM kept in the database of the General Health Insurance Company of the Czech Republic (VZP) which provided health care coverage for 63% of Czech Republic population in 2014. We identified all individuals in the VZP database who had a record of DM diagnosis (E10-E16 based on ICD 10) or who had any antidiabetic therapy prescribed (ATC group A10) in the periods of 2002-2006 and 2010-2014. A cohort of patients was extracted for analysis, who had an agent from A10 group prescribed at least once in a relevant year (n=308,962 in 2002; n=426,695 in 2014). A number of patients was evaluated for each year, who had at least once MET or SU prescribed. The number of patients treated with MET or SU was then expressed as a percentage of all who had any therapy from A10 group prescribed in the year in question. Metformin prescriptions have linearly risen from 43% to 77%, while sulfonylurea prescriptions have linearly decreased from 65% to 37%. The analysis presents the first evaluation of the development of metformin prescriptions conducted in the Czech Republic and evaluation of its concordance with the recommended procedures for the treatment of DM. The amount of metformin prescribed in the Czech Republic increased from 43% to 77% while the amount of SU prescribed decreased from 65% to 37% between 2002 and 2014. This development and the current ratio between the prescribed amounts of MET and SU demonstrate the implementation of the recommended procedures into practice and prove the high quality of care for patients with DM2T in specialists--diabetologists surgeries.

Relatively large socioeconomic inequalities in health and mortality have been observed in Central and Eastern Europe (CEE) and the former Soviet Union (FSU). Yet comparative data are sparse and virtually all studies include only education. The aim of this study is to quantify and compare socioeconomic inequalities in all-cause mortality during the 2000s in urban population samples from four CEE/FSU countries, by three different measures of socioeconomic position (SEP) (education, difficulty buying food and household amenities), reflecting different aspects of SEP. Data from the prospective population-based HAPIEE (Health, Alcohol, and Psychosocial factors in Eastern Europe) study were used. The baseline survey (2002-2005) included 16 812 men and 19 180 women aged 45-69 years in Novosibirsk (Russia), Krakow (Poland), Kaunas (Lithuania) and seven Czech towns. Deaths in the cohorts were identified through mortality registers. Data were analysed by direct standardisation and Cox regression, quantifying absolute and relative SEP differences. Mortality inequalities by the three SEP indicators were observed in all samples. The magnitude of inequalities varied according to gender, country and SEP measure. As expected, given the high mortality rates in Russian men, largest absolute inequalities were found among Russian men (educational slope index of inequality was 19.4 per 1000 person-years). Largest relative inequalities were observed in Czech men and Lithuanian subjects. Disadvantage by all three SEP measures remained strongly associated with increased mortality after adjusting for the other SEP indicators. The results emphasise the importance of all SEP measures for understanding mortality inequalities in CEE/FSU.

Tobacco is the leading cause of cancer in the Czech Republic. More than one-third of the population older than 15 years smokes, including many nurses. Most smokers want to quit, but the extent of nurses' involvement in tobacco cessation is unknown. The purposes of this study are to describe the frequency of nurses' interventions in helping smokers quit, examine their attitudes and skills, and explore the relationship of nurses' smoking status to level of intervention. A convenience sample of nurses in the Czech Republic completed a survey about their frequency of interventions according to the 5As for tobacco dependence treatment (i.e., ask, advise, assess, assist, arrange), their attitudes and perceived skills, and their smoking status (never, former, current). A total of 157 nurses completed the survey; 26% "always" or "usually" assisted patients with smoking cessation. Few (22%) reported that nurses could play an important role in helping patients quit, and 65% rated their ability to help smokers quit as "fair/poor." Nurse who smoked (30%) were less likely to consistently assess smoking status or arrange for follow-up support. Few nurses in the Czech Republic consistently provide smoking cessation support to patients, have the skills to do so, or view this role as an important part of their role. To reduce tobacco-related cancers in the Czech Republic, capacity-building efforts are needed to enhance nurses' skills and confidence in providing smoking cessation interventions. Support is also need to help nurses who smoke quit.

We evaluated the prevalence of hepatitis E virus (HEV) in the pork production chain in Czech Republic, Italy, and Spain during 2010. A total of 337 fecal, liver, and meat samples from animals at slaughterhouses were tested for HEV by real-time quantitative PCR. Overall, HEV was higher in Italy (53%) and Spain (39%) than in Czech Republic (7.5%). HEV was detected most frequently in feces in Italy (41%) and Spain (39%) and in liver (5%) and meat (2.5%) in Czech Republic. Of 313 sausages sampled at processing and point of sale, HEV was detected only in Spain (6%). HEV sequencing confirmed only g3 HEV strains. Indicator virus (porcine adenovirus) was ubiquitous in fecal samples and absent in liver samples and was detected in 1 slaughterhouse meat sample. At point of sale, we found porcine adenovirus in sausages (1%–2%). The possible dissemination of HEV and other fecal viruses through pork production demands containment measures. PMID:22840221

The External Quality Control System (EQAS) of laboratory activities in medical microbiology and parasitology was implemented in the Czech Republic in 1993 with coded sera samples for diagnosis of viral hepatitis and bacterial strains for identification distributed to first participating laboratories. The number of sample types reached 31 in 2003 and the number of participating laboratories rised from 79 in 1993 to 421 in 2003. As many as 15.130 samples were distributed to the participating laboratories in 2003. Currently, almost all microbiology and parasitology laboratories in the Czech Republic involved in examination of clinical material participate in the EQAS. Based on the 11-year experience gained with the EQAS in the Czech Republic, the following benefits were observed: higher accuracy of results in different tests, standardisation of methods and the use of most suitable test kits.

Cardiovascular (CV) mortality was reduced more than 50 % in the Czech population at the turn of the century, due to an improvement of major CV risk factors in the general population, interventional procedures implemented into the treatment of acute coronary events, and new drugs (ACE inhibitors, statins etc.) for CV prevention (Czech MONICA and post-MONICA studies, 1985-2008). An insufficient level of preventive efforts is described in the Czech patients after acute coronary syndrome (Czech part of the EUROASPIRE studies, 1995-2013). Drug underdosing and wrong patients' compliance to life style and drug therapy recommendations represent two main reasons of this unsatisfactory situation. The residual vascular risk of patients with stable coronary heart disease (CHD) is still high due to a poor control of conventional risk factors on the one hand, and due to increasing weight and glucose metabolism abnormalities on the other hand. Patients with insulin resistance and glucose disorders have more frequently non LDL C dyslipidemia (atherogenic dyslipidemia), hypertriglyceridemic waist and high atherogenic index of plasma (AIP>0.24), i.e. markers of residual CV risk. Among others increased dose of statins and combined lipid modifying therapy should be implemented in patients with CHD, diabetes or metabolic syndrome.

Every year official data is published which describes the care of patients with diabetes mellitus in the Czech Republic. An overall number of individuals with diabetes, the number of newly reported cases and the number of patient deaths is always specified. However this data does not allow us to identify the differences in mortality between the individual cohorts of diabetic patients in relation to therapy. Comparison of the mortality development in the periods of 2002-2006 and 2010-2013 in a representative sample of the patient population with type 2 diabetes mellitus using oral antidiabetic drugs, kept in the database of the General Health Insurance Company of the Czech Republic (VZP) which provided health care coverage for 63% of Czech population in 2013. A retrospective epidemiologic analysis. We identified all individuals in the VZP database who had a record of DM diagnosis (E10-E16 based on ICD 10) or who had any antidiabetic therapy prescribed (ATC group A10) in the periods of 2002-2008 and 2009-2013. We only selected those patients for the analysis who were treated with oral antidiabetic medicines (in the given year or the preceding years they had a record of treatment with at least one medicine from A10B group, while having no record of treatment with medicines from A10A group within both years). 237,665 individuals met the selected criteria in 2003 and 315,418 individuals in 2013. Mortality rates dropped for all age groups (from 2003-2013): for 50-59 year olds by 1.2%-0.7%; in 60-69 year olds by 2.6%-1.6%; for 70-79 year olds by 5.8%-3.5%. In 2013 mortality rates came close to the general population where for the same age groups they reached 0.6%, 1.5% and 3.4% respectively. When expressed in relative terms, the mortality among 50-59 year olds declined by 42% (Czechia by 25%), among 60-69 year olds by 39% (Czechia by 17%) and among 70-79 year olds by 40% (Czechia by 28%) from the year 2003. The decline in mortality among the patients with DM treated with oral antidiabetic medicines was greater in both absolute and relative terms in the period of 2003-2013 than among the general population in the Czech Republic. The analysis of mortality among the patients treated with oral antidiabetic medicines, registered in the VZP database, has shown a clearly favourable trend of mortality decline which is faster than among the general population. The fact that mortality among this cohort is getting closer to that among the general population of the corresponding age is a finding of critical importance. There is a justified expectation that mortality, with increasingly extensive utilization of the present therapeutic procedures, will continue to decrease.

Mumps outbreaks, especially in adolescents and young adults, have been reported in the Czech Republic. The aim of the presented study was to determine the seroprevalence of specific IgG antibodies against mumps in the adult population of the Czech Republic. The study was designed as a multicenter serological survey of adults aged 18 years and over. Specific IgG antibodies against mumps were detected in blood samples using an enzyme-linked immunosorbent assay (ELISA). A total of 1,911 serum samples were examined. The overall seropositivity reached 55.3%. In individual age groups, the highest seropositivity 63% (63.5-65.2%) was recorded in adults aged 40 years and over; the lowest seropositivity was found in adults aged 18-29 years (27.4%). The difference in seropositivity rate between the 18-29 years age group and the 40 years and over age groups was statistically significant (p < 0.001). Only the 18-29 years age group included both vaccinated and unvaccinated (born in the pre-vaccine era) individuals. In vaccinated individuals, seropositivity was reported in only 19.1% of persons; in unvaccinated individuals, seropositivity reached 48.2%. Our results demonstrate the long-term persistence of antibodies following natural infection and the decrease in seropositivity that occurs after vaccination over time. This immunity waning may account for the higher susceptibility of adolescents and young adults to mumps. Therefore, the current vaccination program in the Czech Republic could be considered as less effective. It will be modified with the shifting of the second dose of vaccine from two years of age to the preschool age.

2015-03-01

The mortality of colorectal cancer (CRC) is significant worldwide. There is good evidence for benefits of the CRC screening in mortality reduction. Since 2009, the population of the Czech Republic have had two CRC screening options from which to choose: a faecal occult blood test (FOBT) at the age of 50 to be repeated every two years or primary screening colonoscopy (PSC) at the age of 55. General practitioners play a crucial role in the CRC screening programme. The CRC screening adherence of the Czech population is poor and does not exceed 25%. The aims of the study were to analyse the reasons behind the low CRC screening adherence of the Czech population, to classify the populations attitudes, and to identify the barriers. A questionnaire survey was conducted in a Czech energy company with 13,000 employees in 2011-2012. The questionnaire was administered electronically by e-mail or directly at the workplace. The questionnaire response rate was 31.3% (4070). The pool of respondents consisted of 2804 (68.9%) females and 1266 (31.1%) males. Of the respondents, 1345 (33.1%) were aged over 50 years (73.5% women and 26.5% men). Of the cohort aged over 50, 68.65% of women and 63.2% of men took a FOBT. Ten percent of respondents aged over 50 years have never heard of CRC screening and 32.8% of this age category have never participated in CRC screening. The main reasons for not taking a FOBT were feeling well and having no health problems (38.8%) or FOBT not offered the by the general practitioner (27.8%). Other reasons were no time to do so, fear of the result, unsure of the procedure, unawareness of what FOBT is, or uncomfortable about the test procedure. On the other hand, 8.37% of the participants aged between 15 and 39 years and 20.7% of those aged between 40 and 49 years have already taken a FOBT. Overall, 15.4% of respondents prefer the new alternative, PSC, as the CRC screening option. Significant differences in CRC screening adherence are seen between administrative regions of the Czech Republic and between education levels. From the results, it follows that a considerable proportion of the population of the Czech Republic do not understand the principle of CRC screening and its methods. Enough room has been left to promote education on CRC screening for both the public and general practitioners. On the other hand, a large part of proactive individuals participate in CRC screening before the age of 50.

Cancer burden in the Czech population ranks among the highest worldwide, which introduces a strong need for a prospective modelling of cancer incidence and prevalence rates. Moreover, a prediction of number of cancer patients requiring active antitumor therapy is also an important issue. This paper presents the stage-specific predictions of cancer incidence and prevalence, and the stage- and region-specific patients requiring active antitumor therapy for the most common cancer diagnoses in the Czech Republic for years 2015 and 2020. The stage-specific estimates are also presented with regard to the treatment phase as newly diagnosed patients, patients treated for non-terminal recurrence, and patients treated for terminal recurrence. Data of the Czech National Cancer Registry from 1977 to 2011 has been used for the analysis, omitting the records of patients diagnosed as death certificate only or at autopsy. In total, 1,777,775 incidences have been considered for the estimation using a statistical model utilizing solely the population-based cancer registry data. All estimates have been calculated with respect to the changing demographic structure of the Czech population and the clinical stage at diagnosis. Considering year 2011 as the baseline, we predict 89%, 15%, 31% and 32% increase in prostate, colorectal, female breast and lung cancer incidence, respectively, in 2020 resulting in 13,153, 9,368, 8,695, and 8,604 newly dia-g--nosed cancer patients in that year, respectively. Regarding cancer prevalence in 2020, the estimated increase is 140%, 40%, 51%, and 17% for prostate, colorectal, female breast and lung cancer, respectively, meaning that more than 100,000 prevalent female breast cancer patients as well as more than 100,000 prevalent prostate cancer patients are expected in the Czech Republic. The estimated numbers of patients requiring active antitumor therapy for prostate, colorectal, female breast and lung cancer in the Czech Republic in 2020 are 23,652, 14,006, 14,759 and 8,272; respectively. The analysis documents a serious increase in cancer incidence and prevalence in the Czech Republic in years 2015 and 2020 when compared to the situation in 2011. Regarding the estimated numbers of patients requiring active antitumor therapy, the model confirms a continuous increase that must be accounted for in the future planning of health care in the Czech Republic.

To determine the origin of hepatitis E virus in the Czech Republic, we analyzed patient clinical samples. Five isolates of genotypes 3e, 3f, and 3g were obtained. Their genetic relatedness with Czech strains from domestic pigs and wild boars and patient recollections suggest an autochthonous source likely linked to consumption of contaminated pork.

This study analyses the relationship between immigrants' self-reported/rated health (SRH) and their perceived working conditions in Czechia materialized via discrimination, based on the example of Ukrainian immigrants analyzed by gender dimension. The role of age, education, and marital status is also analyzed. A sample of native-born Czechs serves as a reference frame. A cross-sectional design was applied. Using data from two surveys of Ukrainian immigrants in Czechia and a countrywide health interview survey for Czechs, we analyse inequalities in SRH and workplace discrimination loads. Four binary logistic regression models were computed separately for women and men from Ukraine and Czechia to identify the determinants of fair/poor SRH. We found that only Ukrainian immigrant females were heavily exposed to all four measured types of workplace discrimination, thereby modifying and worsening the quality of their SRH. Determinants which are behind respondents' SRH differ between Ukrainian immigrants vis-à-vis Czechs with one exception. The "oldest age group" (41-62) contributes to poorer assessment of SRH among Ukrainian females, Czech females, and Czech males too. The lowest educational level (primary education) correlates with poor SRH within the sample of Czech males.

Population of wild boar is increasing in the whole Europe, the animals migrate close to human habitats which greatly increases the possibility of natural transmission between domestic animals or humans and wild boars. The aim of the study was to estimate in population of free-living wild boar in the Czech Republic the prevalence of enteric viral pathogens, namely rotavirus groups A and C (RVA and RVC), porcine reproductive and respiratory syndrome virus (PRRSV), and members of family Coronaviridae (transmissible gastroenteritis virus - TGEV, porcine epidemic diarrhea virus - PEDV, porcine respiratory coronavirus - PRCV, and porcine hemagglutination encephalomyelitis virus - PHEV) and Picornaviridae,(teschovirus A - PTV, sapelovirus A - PSV, and enterovirus G - EV-G). In our study, stool samples from 203 wild boars culled during hunting season 2014-2015 (from October to January) were examined by RT-PCR. RVA was detected in 2.5% of tested samples. Nucleotide analysis of VP7, VP4, and VP6 genes revealed that four RVA strains belong to G4P[25]I1, G4P[6]I5, G11P[13]I5, and G5P[13]I5 genotypes and phylogenetic analysis suggested close relation to porcine and human RVAs. The prevalence of RVC in wild boar population reached 12.8%, PTV was detected in 20.2%, PSV in 8.9%, and EV-G in 2.5% of samples. During our study no PRRSV or coronaviruses were detected. Our study provides the first evidence of RVC prevalence in wild boars and indicates that wild boars might contribute to the genetic variability of RVA and also serve as an important reservoir of other enteric viruses.

To describe fruit and vegetable intake of pre-school and school children in the Czech Republic and to provide information about their preferences and dietary habits. Cross-sectional dietary survey conducted by the method of repeated 24 h recall on two non-consecutive days. Usual intakes were calculated for three age categories (4-6, 7-10 and 11-14 years). The whole area of the Czech Republic. A subgroup of 602 children aged 4-14 years was extracted from the representative sample of respondents participating in a national dietary survey (SISP) realized in the years 2003 and 2004. Estimated average usual intakes of fruit and vegetables were 209 (sd 69) g/d in children aged 4-6 years, 230 (sd 84) g/d in children aged 7-10 years, and 284 (sd 133) g/d and 261 (sd 140) g/d respectively in boys and girls aged 11-14 years. Only 22 % of children had total daily intake of fruit and vegetables of five or more servings on the day of the survey. Fruits were consumed almost two times more often than vegetables in all age groups studied. The majority of fruit consumption comprised apples and bananas, which made up more than 60 % of the whole fruit intake. Fruiting vegetables were the most frequently consumed group of vegetables. Fruit and vegetable intakes in all age categories were under recommended levels and the diversity of fruit and vegetables consumed by the Czech children was relatively low.

The West Nile virus (WNV) is an important mosquito-borne flavivirus occurring around the world. Occasionally found in Central Europe, the virus spread massively through whole Hungary between 2008 and 2009. The aim of our study was to determine the recent prevalence of the WNV infection in horses in the Czech Republic. Overall, 2349 serum samples, collected from healthy unvaccinated adult horses in the Czech Republic between 2011 and 2013, were tested. A commercially available competitive ELISA kit (cELISA) was used for this purpose and positive samples were confirmed by virus neutralisation tests using WNV and tick-borne encephalitis virus (TBEV). Altogether 271 of 2348 samples (11.5%) were positive by cELISA. Confirmatory VNT revealed 16 WNV positive samples, 11 of which had titres from 8 to 1024; VNTs with TBEV were negative. Three samples had antibodies against both viruses and the WNV antibody titres were less than or equal to the TBEV antibody titres. A cross reactivity of flaviviruses might have had an impact on the results, but in samples with similar WNV and TBEV titres, co-infection with both pathogens cannot be ruled out either. VNT antibody titres in two horses were inconclusive (cut-off titre 4). The place of birth and transfers (if any) were checked for each WNV seropositive horse. Five WNV positive/TBEV negative samples (0.2%) came from five administrative regions (South Bohemian, Karlovy Vary, Central Bohemian, South Moravian, and Moravian-Silesian) and the respective animals were never moved to a foreign country. Four of these horses never left the farm. Other six WNV positive/TBEV negative horses were imported to the Czech Republic from North America or Central and West Europe and therefore, it is not possible to tell unambiguously whether their infection is autochthonous or imported. The results of the present study confirm that WNV antibodies occur sporadically in horses in the Czech Republic. WNV was found to circulate in different parts of the Czech Republic and not only in the South of Moravia.

The aim of this study is to analyze the genotoxic risks in the Moravian-Silesian Region in the Czech Republic and assess the significance of genotoxic factors in the etiology of cancer by bringing together the Registry of Occupational Exposure to Genotoxic Factors and the Cancer Registry and compare the rate of detected cancer in persons exposed to genotoxic factors via their work in the Moravian-Silesian Region with the occurrence of cancer in the population of the Czech Republic. The results show: (a) For the monitored group (748 person) for the period 1996-2008, according to gender, was no statistically significant difference in the incidence of oncological diseases compared to the population of the Czech Republic. (b) But statistically significant difference was found in the cases of oncological diseases in groups according to % AB.C. using the Cytogenetic analysis of human peripheral lymphocytes (CAPL). The highest incidence was in the group with a higher incidence of % AB.C. High values of % AB.C. may predict the development of oncological diseases.

The aim of study was to test the sera of healthy dairy cows by ELISAs, the methods also used in other groups of animals in the Czech Republic, and thus to obtain actual data about N. caninum and T. gondii seroprevalence in cattle. In the Czech Republic, sera from 546 clinically healthy dairy cows (Bos primigenius f. taurus) aged > 2 years from 49 farms in 7 districts were collected. Sera were tested for Neospora caninum antibodies by a commercial competitive-inhibition enzyme-linked immunosorbent assay; samples with more than 30% inhibition were considered as positive. The same samples were also analysed for Toxoplasma-specific IgG antibodies by an enzyme-linked immunosorbent assay; samples with more than 50% S/P were considered as positive. Antibodies against N. caninum were found only in 3 cows (0.5%) with inhibitions of 47, 78 and 85. Antibodies against T. gondii were found in 53 cows (9.7%) with S/P ranging from 51% to over 211%; positive animals were found in 4 of 7 districts, with prevalences ranging from 8% - 14%. Indication of mixed infections (concurrent presence of both N. caninum and T. gondii antibodies) was not proved. The results of the study indicate that dairy cows in the Czech Republic have a relatively low seroprevalence for both N. caninum and T. gondii. Therefore, natural infection with N. caninum and T. gondii seems not to be very common in Czech cattle. These results show actual data about N. caninum and T. gondii infection in healthy dairy cattle from the Czech Republic.

Iodine deficiency is a global public health problem which is particularly noticeable in pregnant or breastfeeding women and their children. Even mild iodine deficiency during pregnancy can lead to damage to the developing brain and thus affecting the fetus intelligence, his cognitive and neurological function, embryogenesis and growth. In the period 2010-2015 was determined by spectrophotometry at the Institute of Endocrinology the basal urinary iodine in 532 pregnant women at the age of 32 ± 5 (18-44) years, which came from Prague, Hradec Kralove and Mlada Boleslav. It was located 349 women in the first trimester, 112 in the second trimester, and 71 women in the third trimester. In the monitoring of pregnant women in the first trimester 218 basal urine samples of women were determined by mass spectrometry with inductively coupled plasma (ICP MS) in The National Institute of Public Health (NIPH). Women came from the 6 areas in the Czech Republic. Development of urinary iodine in the general population in the period 1994-2015 was observed in patients who underwent Institute of Endocrinology and from population studies conducted in 7 regions of the Czech Republic. It performed 52 648 spectrophotometric analysis of urinary iodine in the general population. Urinary iodine was determined by alkali melting of urine samples, followed by spectrophotometric determination of iodine in the form of iodide using the Sandell-Kolthoff reaction in the Institute of Endocrinology or determination was performed by ICP-MS in the laboratory of NIPH. On average, only 21.8 % of pregnant women had urinary iodine values determined by spectrophotometry higher than 150 μg/L. The results of iodine nutrition of pregnant women in the first trimester analyzed using ICP-MS are better, but even so, only 50.5 % of pregnant women have urinary iodine higher than 150 μg/L. The results of iodine nutrition of pregnant women are alarming, on average, only 30 % of the total of 750 examined women have urinary iodine values greater than 150 μg/L and therefore meet the requirements of the WHO for pregnant women. Our results, however, show that iodine deficiency is not major public health problem in the general population.Key words: ICP-MS - pregnant women - Sandell-Kolthoff reaction - urinary iodine.

Developmental changes and gender effects on motivational constructs based on the expectancy-value model in Czech and United States students regarding learning of science, mathematics, and other subjects

NASA Astrophysics Data System (ADS)

Yang, Eun-Mi

This study employed American and Czech student samples to investigate the motivational constructs used in Eccles and Wigfield's (1983) expectancy-value model. To predict achievement behavior, the model specifies relationships among expectancy for-success and task value, task-specific self-concept, perception of task-difficulty, perceptions of social environment, and interpretations and attributions for past events in relation to the social world. Czech and American students (n = 1,145) in grades 4--12 were the participants in this study. The causal relationships among the constructs were tested to investigate structural similarities and differences in the models for both countries. This study also explored developmental changes, gender, and national differences in the students' motivational beliefs for these motivational constructs: Expectancy for Success, Intrinsic Interest Value, Task-specific Self-concept, Perception of Task-difficulty, and Perceived Vocational Gender Dominance for science, mathematics, and other school subjects. The findings indicated that, for both countries, with respect to changes over grade level, compared to the younger students, the older students showed lower motivational beliefs for most subject areas except reading. However, the Czech students in grades 6--8 showed more positive motivational beliefs in life science and social studies than did the Czech students in other grade levels. In comparing genders, the male students exhibited more positive motivational beliefs in physical science than did the female students, and female students showed more positive motivational beliefs in reading than did the male students. For life science, the Czech female students rated Intrinsic Interest Value and Task-specific Self-concept higher than did their peer male students. The American students' motivational beliefs in reading were more positive than were Czech students', and the Czech students held more positive motivational beliefs in life science than did the American students. With minor variations for each country, the expectancy-value model provided a reasonable tool for understanding the causal relationships among the motivational beliefs. For the Czech sample, Perception of Task-difficulty was a strong negative predictor for Expectancy for Success for most school subjects except life science whereas, for the American sample, it was a weak but significant negative predictor for Intrinsic Interest Value for most school subjects except social studies. Implications for science education are discussed.

To provide an overview of gambling and associated problems in the Czech Republic, including an overview of the historical context, legislation, prevalence, treatment and research base and agenda. A review of literature and relevant sources. The trajectory of gambling patterns in the territory of the Czech Republic in the 20th century reflected broad socio-political changes. Those included significant expansion between the wars, strict state control and bans on some gambling activities during the communist regime and finally dynamic development characterized by a boom in electronic gaming machines (EGMs) and increasing accessibility of gambling facilities after 1989, which aggravated gambling-related problems. Many municipalities have banned EGMs, which has created conflict in regulation at state and municipal levels. The draft gambling law prepared in 2014 aims to clarify the regulatory framework. Before 2012 there was only sporadic research interest in gambling, but in 2012 the first complex research on gaming and problem gambling in the Czech population took place. The estimated prevalence of problem gambling is currently 2% in the population aged 15-64 years. Preventive measures, counselling and treatment services for problem gamblers are limited. Weak and ineffective regulation of the gambling market in the Czech Republic during the past 20 years, despite the large growth in gambling, has led to inadequate prevention and response to problem gambling which has become a considerable public health, social and political issue. © 2015 Society for the Study of Addiction.

The environmental occurrence and concentrations of cyanobacterial toxins (cyanotoxins) were investigated in the Czech Republic. Concentrations of microcystins (MCs), cylindrospermopsin (CYN) or saxitoxins (STXs) were determined immunochemically by ELISA assays in 30 water samples collected from the surface layers of 19 reservoirs during the summer season of 2010. MCs were detected in 18 reservoirs and 83 % of samples, with median and maximal concentration being 1.5 and 18.6 μg/L, respectively. The high frequency of MC occurrence coincided with prevalence of cyanobacterium Microcystis sp., which was detected in 87 % samples, followed by Dolichospermum (Anabaena) sp. observed in 33 % samples. CYN was detected by ELISA only in one sample at a concentration of 1.2 μg/L. STXs presence was indicated for the first time in Czech water reservoirs when the toxins were found at low concentrations (0.03-0.04 μg/L) in two samples (7 %) collected from two different reservoirs, where STXs co-occurred with MCs and eventually also with CYN. In both STX-positive samples, the phytoplankton community was dominated by Microcystis sp., but Dolichospermum sp. and/or Aphanizomenon sp. were also present as putative producers of STX and/or CYN. Cyanotoxins commonly occurred in Czech water reservoirs, and MCs frequently at concentrations possibly associated with human health risks. MCs were the most prevalent and abundant cyanotoxins, but also other cyanotoxins were detected, though sporadically. Further research and regulatory monitoring of cyanotoxins other than MCs is therefore required.

Persistent organic pollutants, such as perfluorinated alkylated substances (PFASs) and brominated flame retardants (BFRs) are widespread in the environment and most of them are bioaccumulated in wildlife and humans. The present study is the first investigation to reveal the PFAS and BFR levels of serum samples in the adult population of the Czech Republic. Altogether, 300 serum samples from blood donors in four cities were examined. In all samples 19 PFASs and 33 BFRs, including some of their metabolites, were targeted. The analyses were performed using ultra high performance liquid chromatography coupled with tandem mass spectrometry or gas chromatography with mass spectrometry (according to the type of analyte). PFASs, with the carbon chain length C6 and higher, dominated in all samples. Perfluorooctanesulfonate (PFOS; median: 2.43ng/mL), perfluorooctanoic acid (PFOA; median: 0.756ng/mL), perfluorodecanoic acid (PFDA; median: 0.145ng/mL) and perfluorohexanesulfonate (PFHxS; median: 0.184ng/mL) were detected in 100% of samples. Perfluorononanoic acid (PFNA; median: 0.325ng/mL) and perfluoroundecanoic acid (PFUdA; median: 0.058ng/mL) in 99.7% and 96.0% of samples, respectively. We observed statistically significant associations (p<0.05) between selected PFAS concentrations and the locality, gender, age of donors and education level. None of the BFRs was detected above the LOQ in more than 9% of the samples. The most frequently detected representatives of this group were congeners of polybrominated diphenyl ethers, namely BDE-47 (in 8.7%; range: 0.496-5.44ng/g lipid weight (l.w.)), BDE-99 (in 6.0%; range: 0.706-9.46ng/g l.w.), BDE-153 (in 7.3%; range: 0.736-6.44ng/g l.w.) and BDE-209 (in 7.0%; range: 13.7-2693ng/g l.w.).

(1) Background : An increase in or at least the sustainment of walking activities across a wide section of the population is a crucial health-related task for Central and East European countries. The aim of this study was to assess the associations between adolescents' walking activities and various levels of perceived safety of the built environment in differing socio-demographic backgrounds of Poland and the Czech Republic. Furthermore, we aimed to determine major moderators affecting the walking habits of adolescents in areas with different levels of walkability. (2) Methods : The surveys were conducted during the 2008-2009 and 2013-2014 school years in 24 Polish and 35 Czech secondary schools, with a sample of 2001 adolescents. All participants completed the International Physical Activity Questionnaire-Long Form and the NEWS-Abbreviated. Selected students took part in objective weekly monitoring of physical activity (PA). (3) Results : Boys and girls who perceived their neighborhood environment as the safest were significantly more likely to meet the recommendations for leisure-time walking. Adolescents from the safest environment achieved 11,024 steps/day on average, while those from the least safe environment achieved 9686 steps/day. (4) Conclusions : A safe neighborhood environment significantly predicts walking activities among girls. Environmental safety improvement can support the active transport and better use of leisure time PA.

The development of an unrealistic ideal body image and body size dissatisfaction among children is common in Western countries, including the USA and many European nations. However, little is known about children's body image perceptions in post-communist countries. This pilot study evaluated body image perceptions in a sample of Czech school-aged children and their parents and compared them with the perceptions of American children and parents. Ninety-seven Czech and 45 American 4th-6th graders and their parents from eight urban schools participated in this study. A previously developed silhouette body image instrument was utilized in a parent questionnaire and during child interviews to measure perceived and ideal body image perceptions of children and parents. Descriptive statistics, independent t-tests and paired t-tests were used to compare differences between children's and parents' perceived and ideal body image perceptions. Associations between body image perceptions and other variables were explored using bivariate correlations. American children had a thinner ideal body image compared with Czech children (P < 0.05). However, a larger proportion of Czech boys desired to be thinner compared with American boys (34.2% vs. 20%). Parent's ideal body image for their children did not differ by nationality (P = 0.858). While the pressure on children to look thinner was apparent among both American and Czech children, Czech children considered a larger body size as more ideal. A future study should evaluate body image perceptions and factors influencing these perceptions in a representative sample of Czech children and parents.

Diversity of the TLR4 Immunity Receptor in Czech Native Cattle Breeds Revealed Using the Pacific Biosciences Sequencing Platform.

2017-07-03

The allelic variants of immunity genes in historical breeds likely reflect local infection pressure and therefore represent a reservoir for breeding. Screening to determine the diversity of the Toll-like receptor gene TLR4 was conducted in two conserved cattle breeds: Czech Red and Czech Red Pied. High-throughput sequencing of pooled PCR amplicons using the PacBio platform revealed polymorphisms, which were subsequently confirmed via genotyping techniques. Eight SNPs found in coding and adjacent regions were grouped into 18 haplotypes, representing a significant portion of the known diversity in the global breed panel and presumably exceeding diversity in production populations. Notably, the ancient Czech Red breed appeared to possess greater haplotype diversity than the Czech Red Pied breed, a Simmental variant, although the haplotype frequencies might have been distorted by significant crossbreeding and bottlenecks in the history of Czech Red cattle. The differences in haplotype frequencies validated the phenotypic distinctness of the local breeds. Due to the availability of Czech Red Pied production herds, the effect of intensive breeding on TLR diversity can be evaluated in this model. The advantages of the Pacific Biosciences technology for the resequencing of long PCR fragments with subsequent direct phasing were independently validated.

Health needs of the Roma population in the Czech and Slovak Republics.

In the growing literature on the human rights of Roma people in Central Europe, their relatively poor health status is often mentioned. However, little concrete information exists about the contemporary health status of the Roma in this region. We sought information on the health of the Roma in two of countries with significant Roma minorities, the Czech and Slovak Republics, by means of systematic searches for literature on the health of Roma people published in Czech or Slovak or by authors from the two countries. Published research on health of the Roma population is sparse. The topics that have received attention suggest a focus on concepts of contagion or social Darwinism, indicating a greater concern with the health needs of the majority populations with which they live. What limited evidence exists indicates that the health needs of the Roma population are considerable. With very few exceptions, the health status of Roma is worse than that of non-Roma population in both countries. The burden of communicable disease among Roma is high and diseases associated with poor hygiene seem to be particularly important. Evidence on health care suggests poor communication between Roma and health workers and low uptake of preventative care. The health needs of Roma lack visibility, not only because of the absence of research but also the absence of advocacy on their behalf. Since 1989, Czech and Slovak researchers have largely turned away from health research on particular ethnic groups. This probably reflects a growing sensitivity about stigmatising Roma, but it also makes it difficult to know how their circumstances might be improved. There is a need for further research into the health of Roma people with particular emphasis on non-communicable disease and for interventions that would improve their health.

2008-01-01

Background and Aims Pilosella officinarum (syn. Hieracium pilosella) is a highly structured species with respect to the ploidy level, with obvious cytogeographic trends. Previous non-collated data indicated a possible differentiation in the frequency of particular ploidy levels in the Czech Republic and Slovakia. Therefore, detailed sampling and ploidy level analyses were assessed to reveal a boundary of common occurrence of tetraploids on one hand and higher ploids on the other. For a better understanding of cytogeographic differentiation of P. officinarum in central Europe, a search was made for a general cytogeographic pattern in Europe based on published data. Methods DNA-ploidy level and/or chromosome number were identified for 1059 plants using flow cytometry and/or chromosome counting on root meristem preparations. Samples were collected from 336 localities in the Czech Republic, Slovakia and north-eastern Hungary. In addition, ploidy levels were determined for plants from 18 localities in Bulgaria, Georgia, Ireland, Italy, Romania and Ukraine. Key Results Four ploidy levels were found in the studied area with a contrasting pattern of distribution. The most widespread cytotype in the western part of the Czech Republic is tetraploid (4x) reproducing sexually, while the apomictic pentaploids and mostly apomictic hexaploids (5x and 6x, respectively) clearly prevail in Slovakia and the eastern part of the Czech Republic. The boundary between common occurrence of tetraploids and higher ploids is very obvious and represents the geomorphologic boundary between the Bohemian Massif and the Western Carpathians with the adjacent part of Pannonia. Mixed populations consisting of two different ploidy levels were recorded in nearly 11% of localities. A statistically significant difference in a vertical distribution of penta- and hexaploids was observed in the Western Carpathians and the adjacent Pannonian Plain. Hexaploid populations tend to occur at lower elevations (usually below 500 m), while the pentaploid level is more or less evenly distributed up to 1000 m a.s.l. For the first time the heptaploid level (7x) was found on one site in Slovakia. In Europe, the sexual tetraploid level has clearly a sub-Atlantic character of distribution. The plants of higher ploidy level (penta- and hexa-) with mostly apomictic reproduction prevail in the northern part of Scandinavia and the British Isles, the Alps and the Western Carpathians with the adjacent part of Pannonia. A detailed overview of published data shows that extremely rare records on existence of diploid populations in the south-west Alps are with high probability erroneous and most probably refer to the closely related diploid species P. peleteriana. Conclusions The recent distribution of P. officinarum in Europe is complex and probably reflects the climatic changes during the Pleistocene and consequent postglacial migrations. Probably both penta- and hexaploids arose independently in central Europe (Alps and Carpathian Mountains) and in northern Europe (Scandinavia, Great Britain, Ireland), where the apomictic plants colonized deglaciated areas. We suggest that P. officinarum is in fact an amphidiploid species with a basic tetraploid level, which probably originated from hybridizations of diploid taxa from the section Pilosellina.

Wide distribution of chlorinated paraffins in the environment has already been demonstrated in several studies; however, information about their levels in the Central Europe is still very limited. First study focused on the SCCP contamination of the Czech aquatic environment have been performed recently, and its results motivated the authors to analyze sediments from a wide set of the Czech rivers in order to obtain more detailed information. Thirty-six sediment samples from eleven rivers and five drainage vents neighboring the chemical factories were analyzed; special attention was paid to the industrial areas. For the first time in the Czech Republic, medium-chain in addition to short-chain chlorinated paraffins were analyzed using GC-ECNI-MS. Chlorinated paraffins were detected in sediment samples on the concentration levels up to 347 ngg(-1) for short-chain chlorinated paraffins, and 5575 ngg(-1) for medium-chain chlorinated paraffins. Average chlorination degree of SCCPs was 65%.

2016-04-01

Synchronous fluorescence spectroscopy was used in combination with principal component analysis (PCA) and linear discriminant analysis (LDA) for the differentiation of plum spirits according to their geographical origin. A total of 14 Czech, 12 Hungarian and 18 Slovak plum spirit samples were used. The samples were divided in two categories: colorless (22 samples) and colored (22 samples). Synchronous fluorescence spectra (SFS) obtained at a wavelength difference of 60 nm provided the best results. Considering the PCA-LDA applied to the SFS of all samples, Czech, Hungarian and Slovak colorless samples were properly classified in both the calibration and prediction sets. 100% of correct classification was also obtained for Czech and Hungarian colored samples. However, one group of Slovak colored samples was classified as belonging to the Hungarian group in the calibration set. Thus, the total correct classifications obtained were 94% and 100% for the calibration and prediction steps, respectively. The results were compared with those obtained using near-infrared (NIR) spectroscopy. Applying PCA-LDA to NIR spectra (5500-6000 cm(-1)), the total correct classifications were 91% and 92% for the calibration and prediction steps, respectively, which were slightly lower than those obtained using SFS.

2000-01-01

In Czech raw water sources for drinking water supply, Cryptosporidium was found in numbers from 0 to 7400 per 100 liters and Giardia from 0 to 485 per 100 liters. The summer floods of 1997 probably brought the highest numbers of Cryptosporidium oocysts into one of the reservoirs sampled; since then these numbers decreased steadily. A relatively high number of Cryptosporidium oocysts was found in one sample of treated water. Repeated sampling demonstrated that this was a sporadic event. The reason for the presence of Cryptosporidium in a sample of treated drinking-water is unclear and requires further study.

Adult attention-deficit/hyperactivity disorder (ADHD) has been added as a diagnosis to the Diagnostic and Statistical Manual of Mental Disorders version 5 (DSM5) in 2013, thus making ADHD, which has been classically known as a childhood disorder, a life-long disorder. Those suffering from the condition show very specific behavioral traits, which manifest as lifestyle habits; they also show comorbidities that can be the symptoms and/or consequences of certain lifestyles. The targeted population was adults aged 18-65 years. The total sample was 1,012 (507 males and 505 females). The Adult ADHD Self-Report Scale (ASRS V. 1.1) was administered to evaluate the current symptoms of ADHD and a questionnaire regarding lifestyles that are pertinent to ADHD, exercise, drug use, and diet. An ASRS score of 4-6 points was found in 11.4% of the male population and 9.7% of the female population (5-6 points indicate very high-intensity symptoms). A score of 6, the highest intensity of symptomatology, was found in 1.18% of males and 0.99% of females. Gender differences in scores were not statistically significant. In terms of self-reported lifestyles, we calculated an ordered logistic regression and the odds ratios of those with ASRS scores >4. Those with higher ASRS scores had higher rates of self-reported unhealthy lifestyles and poor diets with high consumption of sweets. We also ascertained a paradoxical finding that is not in line with the current literature on the disorder - lower rates of cigarette smoking among people with higher ADHD symptomatology. Several specific lifestyles were found to be associated with higher ADHD symptoms such as poor diet and cannabis use. Other factors classically associated with the disorder such as cocaine addiction and nicotinism were either insignificant or surprisingly less prominent among the Czech sample. However, ADHD-prone respondents reported to be more physically active, which fits the clinical picture of hyperactivity but contrasts with literature that reports sedentary ADHD lifestyle.

One of the most fundamental issues in forensic anthropology is the determination of sex and population affinity based on various skeletal elements. Therefore, we compared the sexual dimorphism of the upper facial skeleton from a recent Czech population (twenty-first century) with that of a population from Early Modern Age Bohemia (sixteenth to eighteenth centuries). Methods of geometric morphometrics were applied. According to the results, sexual dimorphism in terms of size, shape, and form was statistically significant in both populations. The best results of sex estimation originated from analyses of form. Thus, both size and shape differences should be taken into account for determination of the sex. The accuracy of prediction achieved 91.1% for individuals in the recent population and 87.5% for individuals from the early modern population. Only minor differences were found between sexual dimorphism in the studied populations. We conclude that sexual dimorphism of the upper facial skeleton is stable during the relatively short time period.

Genetic Diversity of Blumeria graminis f. sp. hordei in Central Europe and Its Comparison with Australian Population

2016-01-01

Population surveys of Blumeria graminis f. sp. hordei (Bgh), a causal agent of more than 50% of barley fungal infections in the Czech Republic, have been traditionally based on virulence tests, at times supplemented with non-specific Restriction fragment length polymorphism or Random amplified polymorphic DNA markers. A genomic sequence of Bgh, which has become available recently, enables identification of potential markers suitable for population genetics studies. Two major strategies relying on transposable elements and microsatellites were employed in this work to develop a set of Repeat junction markers, Single sequence repeat and Single nucleotide polymorphism markers. A resolution power of the new panel of markers comprising 33 polymorphisms was demonstrated by a phylogenetic analysis of 158 Bgh isolates. A core set of 97 Czech isolates was compared to a set 50 Australian isolates on the background of 11 diverse isolates collected throughout the world. 73.2% of Czech isolates were found to be genetically unique. An extreme diversity of this collection was in strong contrast with the uniformity of the Australian one. This work paves the way for studies of population structure and dynamics based on genetic variability among different Bgh isolates originating from geographically limited regions. PMID:27875588

The Czech Republic is characterized by high alcohol consumption and is well known as the world's biggest consumer of beer. In contrast, the alcohol consumption in Norway is relatively low. In this article, we describe and discuss alcohol policy development in the Czech Republic since the mid-1980s to the present and its impact on the alcohol consumption and compare our findings, including the dynamics of the total alcohol consumption and the development of drinking patterns among young people, with the situation in Norway. The study uses the methodology of "process tracing". Selected national statistics, research outcomes and related policy documents were analyzed to identify possible relations between the alcohol consumption and the alcohol policy in two different environments and institutional/policy settings. There was a clear difference in alcohol consumption trends in both countries in the last three decades. Norway was characterized by low alcohol consumption with tendency to decline in the last years. In contrast, the Czech Republic showed an upward trend. In addition, alcohol consumption among Czech youth has been continuously increasing since 1995, whereas the opposite trend has occurred in Norway since the late 1990s. The results revealed that the alcohol-control policies of the Czech Republic and Norway were significantly different during the study period. Norway had a very restrictive alcohol policy, in contrast to the liberal alcohol policy adopted in the Czech Republic, in particular after political transition in 1990. Liberalization of social life together with considerable decline of alcohol price due to complete privatization of alcohol production and sale contributed to an increase of the alcohol consumption in the Czech Republic. Persistently high alcohol consumption among general population and its growth among young people in the Czech Republic pose social, economic and health threats. Norway could provide the inspiration to Czech politicians about effective options in combating these threats. Copyright© by the National Institute of Public Health, Prague 2017

The aim of the study is to examine cross-sectional time trends of life satisfaction and self-rated health in a representative sample of Czech children aged 11, 13 and 15 years using the Health Behaviour in School-aged Children (HBSC) study data from the Czech Republic. Data from survey years 2002, 2006, 2010 and 2014 was used. The sample consisted of 16,357 participants (48.5% of boys). Life satisfaction (LS) was measured by Cantril's ladder; self-rated health was measured through the simple item "Would you say your health is: excellent, good, fair, poor". Most of the children were satisfied with their lives in all surveyed years (mean LS scores range from 7.21 to 7.51; maximum 10). LS was consistently significantly associated (p<0.001) with age and gender. Overall, children and adolescents in the Czech Republic also reported good health. In total, 87.6% of respondents from all samples reported their health as excellent or good. Gender was found to be significantly associated with self-rated health (p<0.05) in all surveyed years. No permanent trends in both followed indicators have been seen in the examined period. Copyright© by the National Institute of Public Health, Prague 2017

The goal of this study was to assess specific features of risk management from the point of view of nurses in leadership positions in inpatient units in Czech hospitals. The study was performed using a quantitative research strategy, i.e., a questionnaire. The data sample was analyzed using SPSS v. 23.0. Pearson's chi-square and analysis of adjusted residues were used for identifying the existence associations of nominal and/or ordinal quantities. 315 nurses in leadership positions working in inpatient units of Czech hospitals were included in the sample. The sample was created using random selection by means of quotas. Based on the study results, statistically significant relations between the respondents' education and the utilization of methods to identify risks were identified. Furthermore, statistically significant relationships were found between a nurse's functional role within the system and regular analysis and evaluation of risks and between the type of the healthcare facility and the degree of patient involvement in risk management. The study found statistically significant correlations that can be used to increase the effectiveness of risk management in inpatient units of Czech hospitals. From this perspective, the fact that patient involvement in risk management was only reported by 37.8% of respondents seems to be the most notable problem.

Several studies examined the fine-scale structure of human genetic variation in Europe. However, the European sets analyzed represent mainly northern, western, central, and southern Europe. Here, we report an analysis of approximately 166,000 single nucleotide polymorphisms in populations from eastern (northeastern) Europe: four Russian populations from European Russia, and three populations from the northernmost Finno-Ugric ethnicities (Veps and two contrast groups of Komi people). These were compared with several reference European samples, including Finns, Estonians, Latvians, Poles, Czechs, Germans, and Italians. The results obtained demonstrated genetic heterogeneity of populations living in the region studied. Russians from the central part of European Russia (Tver, Murom, and Kursk) exhibited similarities with populations from central–eastern Europe, and were distant from Russian sample from the northern Russia (Mezen district, Archangelsk region). Komi samples, especially Izhemski Komi, were significantly different from all other populations studied. These can be considered as a second pole of genetic diversity in northern Europe (in addition to the pole, occupied by Finns), as they had a distinct ancestry component. Russians from Mezen and the Finnic-speaking Veps were positioned between the two poles, but differed from each other in the proportions of Komi and Finnic ancestries. In general, our data provides a more complete genetic map of Europe accounting for the diversity in its most eastern (northeastern) populations. PMID:23505534

Research on physical activity in relation to obesity gradually becomes more focused on environmental determinants, which can potentially influence people's health choices. The present article addresses the topic of physical activity from a wider sociological perspective. Our pilot study was designed with the objective of testing the applicability of a method included in the EC 6th Framework Programme EURO-PREVOB, in the Czech context. The method examines specific determinants of the built environment that can have an impact on physical activity at the population level. In addition, the study aims to analyze possible differences in built environment indicators and their relation to the physical activity of people living in neighbourhoods with areas of varying socioeconomic status. The field study was carried out in the city of Brno, Czech Republic, in 5 neighbourhood quintiles, i.e. areas divided according to the socioeconomic status of local residents. In each quintile, we evaluated the quality of the built environment according to the quality, aesthetics and safety of segregated cycle facilities, playgrounds/playing areas, public open spaces, marked road crossings and pavements as well as signs of incivilities and devastation. Between the five quintiles, significant differences were found in the quality of parks and playgrounds/playing areas, pavements, marking of pedestrian crossings, and in general aesthetics, i.e. signs of incivilities and devastation of the built environment. No differences were found in the quality and use of cycle facilities. The method we used for the evaluation of the built environment proved highly applicable in Czech populated areas. Monitoring of built environment indicators in the Czech Republic should provide a basis for health maps, showing potential associations between the prevalence of high-incidence, non-infectious diseases and various social determinants of physical activity. This information might help in achieving an improvement in these determinants at a community level and promoting an increase in physical activity at the population level.

Polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) from the group of persistent organic pollutants are detected in human tissues years or even decades after their ban. Exposure to PCBs and OCPs can pose risks to human health. In the present study, we calculated the daily intakes of PCBs and OCPs in the Czech population and investigated the long-term trends of human exposure to POPs. Data on POP concentrations from a 16-year period of breast-milk monitoring were used. A toxicokinetic model with consideration of compound-specific elimination half-lives was used to calculate the mothers' daily intake of PCBs and OCPs representing the intake of POPs by all exposure routes. The calculated intakes were compared with dietary intakes calculated by the Czech National Institute of Public Health. The comparison shows good agreement of both intake estimates with decreasing intake trends of POPs in the Czech population in the time period studied. However, several fluctuations with peaks of higher levels were observed in both datasets which are not typical for the period after the ban of use and production of POPs. The available evidence suggests that the increases in chemical concentrations might be caused by food contamination. The calculated intakes of compounds with longer elimination half-lives, such as higher-chlorinated PCBs, were higher in older mothers. This "memory effect" was already observed in other studies and indicates higher exposure in earlier life periods of the mother. Our results suggest that exposure to POPs is still relevant for the Czech population in the period after the ban of the use and production of POPs (post-ban period), especially via food ingestion, though the intake trends are decreasing. Possible food contamination by POPs in the post-ban period requires further assessment. Copyright © 2017 Elsevier Ltd. All rights reserved.

Spatial distribution of a population at risk: an important factor for understanding the recent rise in tick-borne diseases (Lyme borreliosis and tick-borne encephalitis in the Czech Republic).

Recent rise in tick-borne diseases in many parts of Europe is a phenomenon in need of an explanation. We analyzed temporal trends in spatial distribution of a population at risk of Lyme borreliosis, tick-borne encephalitis, and as a control, also of a 'non-tick-borne disease' in the Czech Republic in 1997-2010. Analysis revealed that the population's exposure had been increasingly confined to the nearest surroundings of residences or in totally residential locations and that the incidence of the diseases depended in some causal way on how close to residences people exposed themselves to the risk. The rise in Lyme borreliosis and tick-borne encephalitis was solely due to infections acquired at or near patients' homes (<5 km), while the number of cases acquired further away was decreasing. The detected patterns in the data question some of the hypotheses which may be applicable in explaining the rise in disease incidences in the Czech Republic including the effect of climate change. Potentially causal factors are discussed. Copyright © 2013 Elsevier GmbH. All rights reserved.

The purpose of this study was to evaluate the homogeneity of Polish populations with respect to STRs chosen as core markers of the Polish Forensic National DNA Intelligence Database, and to provide reference allele frequencies and to explore the genetic interrelationship between Poland and neighboring countries. The allele frequency distribution of 10 STRs included in the SGMplus kit was analyzed among 2176 unrelated individuals from 6 regional Polish populations and among 4321 individuals from Germany (three samples), Austria, The Netherlands, Sweden, Czech Republic, Slovakia, Belarus, Ukraine and the Russian Federation (six samples). The statistical approach consisted of AMOVA, calculation of pairwise Rst values and analysis by multidimensional scaling. We found homogeneity of present day Poland and consistent differences between Polish and German populations which contrasted with relative similarities between Russian and German populations. These discrepancies between genetic and geographic distances were confirmed by analysis of an independent data set on Y chromosome STRs. Migrations of Goths, Viking influences, German settlements in the region of Volga river and/or forced population resettlements and other events related to World War II are the historic events which might have caused these finding.

Henriet, F; Bodson, B; Morales, R Meza

2013-01-01

Silky bent grass (Apera spica-venti (L.) P. Beauv.) is a common weed of cereal crops widely spread in Northern and Easthern Europe (Germany, Czech Republic,...), Northern Asia, Siberia and Canada. Up to now, no resistant case has been detected in Belgium but some chemical weeding failures have been observed in Wallonia fields. During summer 2011, 37 seed samples of Apera spica-venti were collected in Wallonia and submitted to resistance tests in controlled conditions. Three modes of action were tested: acetyl coenzyme-A carboxylase inhibitors (pinoxaden and cycloxydim), acetolactate synthase inhibitors (mesosulfuron+iodosulfu-ron, pyroxsulam and sulfometuron) and photosynthesis inhibitors (isoproturon). One susceptible standard population was included in the test in order to validate it and to permit wild populations classification according to "R" rating system developed by Moss et al (2007). Most of populations were susceptible but some populations showed resistance to at least one of the three tested modes of action.

Health literacy survey was carried out at the end of 2014 in the context of preparation of implementation strategy of the Program Health 2020 in the Czech Republic. The survey was conducted by the National Institute of Public Health with financial support from the Ministry of Health and the Czech WHO office. Sociological survey replicated comparative research conducted in eight EU countries in the first half of this decade. Representative survey in 1037 respondents in the age over 16 years, selected in all regions of the country. The identical methodology as used in the original study was utilized. Health literacy was measured in the areas of health care, disease prevention and health promotion.We found that 59,4 % of respondents showed limited general health literacy; health literacy in health care is proved to be 49.5 % of the population, in the area of disease prevention it was 54.1 % respondents and in health promotion it was even even 64.3 % of respondents. Compared to the other countries surveyed, Czech Republic occupies the eighth, penultimate place. Health literacy is correlated negatively with age and positively with education. We found a strong social gradient of health literacy which rises with social status. Health literacy quite significantly influences the health status and health behaviors.Key words: health literacy, health behaviour, health promotion, social determinants of health.

The complete genome sequences of two strains of variola virus (VARV) sampled from human smallpox specimens present in the Czech National Museum, Prague, were recently determined, with one of the sequences estimated to date to the mid-19th century. Using molecular clock methods, the authors of this study go on to infer that the currently available strains of VARV share an older common ancestor, at around 1350 AD, than some recent estimates based on other archival human samples. Herein, we show that the two Czech strains exhibit anomalous branch lengths given their proposed age, and by assuming a constant rate of evolutionary change across the rest of the VARV phylogeny estimate that their true age in fact lies between 1918 and 1937. We therefore suggest that the age of the common ancestor of currently available VARV genomes most likely dates to late 16th and early 17th centuries and not ~1350 AD.

While magnetoreception in birds has been studied intensively, the literature on magnetoreception in bony fish, and particularly in non-migratory fish, is quite scarce. We examined alignment of common carps (Cyprinus carpio) at traditional Christmas sale in the Czech Republic. The sample comprised measurements of the directional bearings in 14,537 individual fish, distributed among 80 large circular plastic tubs, at 25 localities in the Czech Republic, during 817 sampling sessions, on seven subsequent days in December 2011. We found that carps displayed a statistically highly significant spontaneous preference to align their bodies along the North-South axis. In the absence of any other common orientation cues which could explain this directional preference, we attribute the alignment of the fish to the geomagnetic field lines. It is apparent that the display of magnetic alignment is a simple experimental paradigm of great heuristic potential. PMID:23227241

The External Quality Control (EQC) system in activities of laboratories engaged in medical microbiology and parasitology was established in the Czech Republic in 1993 when to the first laboratories which applied coded serum samples were sent for diagnosis of viral hepatitis and bacterial strains for identification. In the course of years the number of control areas increased and in 2000 there were 31 and the number of those interested in participation in EQC increased from 79 in 1993 to 434 in 2000. This year a total of 13,239 samples will be sent to laboratories. Gradually thus almost all microbiological and parasitological laboratories concerned with examination of clinical material became involved. Seven-year experience with EQC in the Czech Republic revealed that gradually the results of various examinations became more accurate, that methods became standardized and the most suitable examination sets are used.

Šošovičková, R; Smetana, J; Beranová, E; Kučerová, K; Chlíbek, R

Viral hepatitis A continues to occur in the Czech Republic due to the high susceptibility of the population and existing opportunities for the transmission of the disease. The aim was to describe and analyse the incidence of viral hepatitis A in the Hradec Králové Region in the Czech Republic in 2005-2014, including the study of two outbreaks that required a different approach of field epidemiologists. In 2015, a retrospective analysis was carried out of the data on the incidence of viral hepatitis A in Hradec Králové Region in 2005-2014. The EPIDAT system where cases of infectious diseases and data from epidemiological investigations are reported was used as a data source for the purposes of the present analysis. In addition, two final reports on epidemic outbreaks of viral hepatitis A from 2014 were assessed. The incidence of viral hepatitis A at the regional level follows, to a certain extent, the pattern of the incidence of this disease at the national level. The highest number of cases was reported in 2010 due to a country-wide epidemic. The most affected age groups were children, adolescents, and young adults. The incidence of viral hepatitis A in individual years has a significant effect on the emergence of local outbreaks. The incidence of viral hepatitis A in the Czech Republic has a fluctuating trend, at both the national and regional levels. The highest incidence of viral hepatitis A was observed in the younger and middle-age categories. The high susceptibility of these population groups suggests the importance of vaccination against viral hepatitis A that confers specific personal protection.Key words: viral hepatitis A - incidence - outbreak - Czech Republic.

In 2007, Poland, the Czech Republic, and Slovakia joined the Schengen Agreement, abolishing restrictions on people crossing the borders. Currently, these areas are places of population movements for economic, family, and touristic reasons. This favors the transmission of infectious diseases, including tuberculosis, and requires enhanced control over the spread of the source of infection in the population of patients living in the border areas. The aim of this study was to investigate the genetic relatedness among Mycobacterium tuberculosis complex strains isolated from patients living in 3 border areas: Poland, the Czech Republic, and Slovakia. PATIENTS AND METHODS The study group consisted of 209 patients with tuberculosis diagnosed and treated between 2007 and 2011 in health care facilities in the Silesia Province in Poland (121 patients [58%]), Žilina in Slovakia (57 [27%]), and the Moravian-Silesian Region in the Czech Republic (31 [15%]). Genotyping of strains was performed using spoligotyping and IS6110-Mtb1-Mtb2 polymerase chain reaction. Among 209 strains, 23 molecular families (clusters) were identified. Seventeen clusters were identified as national. Six international clusters consisted of 30 strains isolated from patients of various nationalities. We identified 6 potential outbreaks of tuberculosis transmission between patients of different nationalities. The circumstances favorable to potential contacts of patients included mainly travelling to the neighboring countries, hospital stays, and addictions. However, there was no evidence of an epidemiological link between these patients, so it may be assumed that if they had come in contact with one another, it was accidental. We observed that the greater incidence of tuberculosis on the Polish territory did not affect the incidence in the Czech Republic or Slovakia over the analysis period.

137 Cs is one of the most important radionuclides released in the course of atmospheric nuclear weapon tests and during accidents in nuclear power plants such as that in Chernobyl, Ukraine, or Fukushima, Japan. The aim of this study was to compare 137 Cs and 40 K concentrations in particular species of mushrooms from selected locations in the Bohemian Forest (Czech: Šumava), Czech Republic, where a considerable contamination from the Chernobyl accident had been measured in 1986. Samples were collected between June and October 2014. Activities of 137 Cs and 40 K per dry mass were measured by means of a semiconductor gamma spectrometer. The 137 Cs values measured range from below detection limit to 4300 ± 20 Bq kg -1 , in the case of 40 K from 910 ± 80 to 4300 ± 230 Bq kg -1 . Differences were found between individual locations, due to uneven precipitation in the course of the movement of the radioactive cloud after the Chernobyl accident. There are, however, also differences between individual species of mushrooms from identical locations, which inter alia result from different characteristics of the soil and depths of mycelia. The values measured are compared with established limits and exposures from other radiation sources present in the environment. In general, it can be stated that the values measured are relatively low and the effects on the health of the population are negligible compared to other sources of ionizing radiation.

In the present study, we have developed an allele-specific primer-polymerase chain reaction (ASP-PCR) for genotyping a single nucleotide polymorphism (SNP) of swine Toll-like receptor 2 (TLR2) (C406G), which is related to the prevalence of pneumonia caused by Mycoplasma hyopneumoniae. We also compared the allele frequency among several pig breeds of Japan and the Czech Republic. Allele-specific primers were constructed by introducing 1-base mismatch sequence before the SNP site. The swine TLR2 C406G mutation was successfully determined by the ASP-PCR using genomic DNA samples in Japan as previously genotyped by a sequencing method. Using the PCR condition determined, genomic DNA samples from pig blood obtained from 110 pigs from 7 different breeds in the Czech Republic were genotyped by the ASP-PCR. The genotyping results from the ASP-PCR were completely matched with the results from the sequencing method. The allele frequency of the swine TLR2 C406G mutation was 27.5% in the Czech Republic and 3.6% in Japan. The C406G mutation was only found in the Landrace breed in Japan, and was almost exclusively found in the Landrace breed in the Czech Republic as well. These results indicated the usefulness of ASP-PCR for detecting a specific SNP for swine TLR2.

Genome-wide association studies have resulted in the identification of the FTO gene as an important genetic determinant of diabetes mellitus. The aim of this study was to confirm the role of this gene in the development of DM in the Czech-Slavonic population and to analyse whether this gene is associated with common DM complications. Two groups of patients (814 with T1DM and 848 with T2DM) and a group of healthy controls (2339 individuals) - both of Czech origin - were genotyped for the FTO rs17817449 SNP. ANOVA and logistic regression were used for the statistical evaluations. The frequency of the GG genotype was significantly higher in T2DM (25.4% vs. 16.7%, P<0.0005) but not in T1DM patients (19.3% vs. 16.7%, P=0.20) than in controls. The increased risk of development of diabetic nephropathy was observed both for T1DM patients (GG vs. TT homozygotes, P<0.01) and T2DM patients (G carriers vs. TT homozygotes, P<0.05). FTO genotype predicted the development of diabetic neuropathy (GG vs. TT comparison; P<0.01) in the T2DM patients only. No association between FTO genotype and development of retinopathy was detected. All presented values are after adjustment for age, sex, BMI and duration of diabetes. We confirm the association between the FTO rs17817449 SNP and susceptibility to T2DM in the Czech-Slavonic population. The same variant is associated with a spectrum of chronic complications in both types of diabetes. Copyright © 2017 Elsevier B.V. All rights reserved.

The History of Slavs Inferred from Complete Mitochondrial Genome Sequences

To shed more light on the processes leading to crystallization of a Slavic identity, we investigated variability of complete mitochondrial genomes belonging to haplogroups H5 and H6 (63 mtDNA genomes) from the populations of Eastern and Western Slavs, including new samples of Poles, Ukrainians and Czechs presented here. Molecular dating implies formation of H5 approximately 11.5–16 thousand years ago (kya) in the areas of southern Europe. Within ancient haplogroup H6, dated at around 15–28 kya, there is a subhaplogroup H6c, which probably survived the last glaciation in Europe and has undergone expansion only 3–4 kya, together with the ancestors of some European groups, including the Slavs, because H6c has been detected in Czechs, Poles and Slovaks. Detailed analysis of complete mtDNAs allowed us to identify a number of lineages that seem specific for Central and Eastern Europe (H5a1f, H5a2, H5a1r, H5a1s, H5b4, H5e1a, H5u1, some subbranches of H5a1a and H6a1a9). Some of them could possibly be traced back to at least ∼4 kya, which indicates that some of the ancestors of today's Slavs (Poles, Czechs, Slovaks, Ukrainians and Russians) inhabited areas of Central and Eastern Europe much earlier than it was estimated on the basis of archaeological and historical data. We also sequenced entire mitochondrial genomes of several non-European lineages (A, C, D, G, L) found in contemporary populations of Poland and Ukraine. The analysis of these haplogroups confirms the presence of Siberian (C5c1, A8a1) and Ashkenazi-specific (L2a1l2a) mtDNA lineages in Slavic populations. Moreover, we were able to pinpoint some lineages which could possibly reflect the relatively recent contacts of Slavs with nomadic Altaic peoples (C4a1a, G2a, D5a2a1a1). PMID:23342138

The Role of Game (Wild Boar and Roe Deer) in the Spread of Tick-Borne Encephalitis in the Czech Republic

2014-01-01

Abstract In the Czech Republic, the incidence of human tick-borne encephalitis (TBE) has been increasing over the last two decades. At the same time, populations of game have also shown an upward trend. In this country, the ungulate game is the main host group of hosts for Ixodes ricinus female ticks. This study examined the potential contribution of two most widespread game species (roe deer [Capreolus capreolus] and wild boar [Sus scrofa]) to the high incidence of TBE in the Czech Republic, using the annual numbers of culls as a proxy for the game population. This was an ecological study, with annual figures for geographical areas—municipalities with extended competence (MEC)—used as units of analysis. Between 2003 and 2011, a total of 6213 TBE cases were reported, and 1062,308 roe deer and 989,222 wild boars were culled; the culls of roe deer did not demonstrate a clear temporal trend, but wild boar culls almost doubled (from 77,269 to 143,378 per year). Statistical analyses revealed a positive association between TBE incidence rate and the relative number of culled wild boars. In multivariate analyses, a change in the numbers of culled wild boars between the 25th and 75th percentile was associated with TBE incidence rate ratio of 1.23 (95% confidence interval 1.07–1.41, p=0.003). By contrast, the association of TBE with culled roe deer was not statistically significant (p=0.481). The results suggest that the size of the wild boar population may have contributed to the current high levels and the rising trend in incidence of TBE, whereas the regulated population of roe deer does not seem to be implicated in recent geographical or temporal variations in TBE in the Czech Republic.

Tuberculosis currently remains a serious medical problem, therefore increased attention is being paid to this disease. Paleopathological studies focused on the monitoring of morbid changes in skeletal remains of historical populations facilitate a detailed study of the development of this disease. They provide direct evidence of the existence of tuberculosis and its past forms. In addition to literary and iconographic sources, the present study is focused on recording the findings of bone tuberculosis in historical osteological sets from the Czech Lands and is the starting point for their detailed review. Approximately 76 cases of bone tuberculosis from the Czech Lands have been published and more or less reliably documented from 20 archeological sites dated back from the Eneolithic to the modern period.

Congenital cataract, facial dysmorphism and demyelinating neuropathy (CCFDN) in 10 Czech gypsy children – frequent and underestimated cause of disability among Czech gypsies

PubMed Central

2014-01-01

Background Congenital Cataract Facial Dysmorphism and demyelinating Neuropathy (CCFDN, OMIM 604468) is an autosomal recessive multi-system disorder which was first described in Bulgarian Gypsies in 1999. It is caused by the homozygous founder mutation c.863 + 389C > T in the CTDP1 gene. The syndrome has been described exclusively in patients of Gypsy ancestry. The prevalence of this disorder in the Gypsy population in the Czech Republic and Central Europe is not known and is probably underestimated and under-diagnosed. Methods We clinically diagnosed and assessed 10 CCFDN children living in the Czech Republic. All patients are children of different ages, all of Gypsy origin born in the Czech Republic. Molecular genetic testing for the founder CTDP1 gene mutation was performed. Results All patients are homozygous for the c.863 + 389C > T mutation in the CTDP1 gene. All patients presented a bilateral congenital cataract and microphthalmos and had early cataract surgery. Correct diagnosis was not made until the age of two. All patients had variably delayed motor milestones. Gait is characteristically paleocerebellar in all the patients. Mental retardation was variable and usually mild. Conclusions Clinical diagnosis of CCFDN should be easy for an informed pediatrician or neurologist by the obligate signalling trias of congenital bilateral cataract, developmental delay and later demyelinating neuropathy. Our data indicate a probably high prevalence of CCFDN in the Czech Gypsy ethnic subpopulation. PMID:24690360

Framed by Michel Foucault’s theory of biopower, it summarizes the history of these abuses and describes human rights campaigns involving domestic and international litigation, advocacy, and grassroots activism, as well as the responses of the Czech governments. The paper describes how legal and policy work during the past decade has led to recognition of coercive, forced, and involuntary sterilization as a present-day human rights issue worldwide, to the adoption of new guidelines on female sterilization, and to a joint statement on the issue by seven UN agencies. Relying on academic literature, reports by domestic and international human rights groups, state investigations, judgments from Czech courts and the European Court of Human Rights (ECHR), media reports, and the experience of the authors, who have been allies of the Romani women harmed in the Czech Republic since 2005 and 2012, respectively, the paper describes the current state of play with respect to achieving redress for them, including current conceptual, legal, political, and social obstacles and their antecedents in 20th century notions of population control.

Based on analysis of epidemiological characteristics, to determine trends in the incidence of imported transmissible diseases in the Czech Republic and to draw attention to the epidemiological significance of international tourism and migration. In cooperation with the National Reference Centre for Epidemiological Data Analysis, National Institute of Public Health Prague, the nationwide Epidat information system databases from 1993 to 2005 were analyzed using software Epi Info version 6.04d. Between 1993 and 2005, altogether 12,091 cases of transmissible diseases were imported into the Czech Republic from 168 countries in the world. The notified annual incidence of imported infections ranges from 206 to 1,714 cases. The highest percentage of cases was imported by Czech tourists (50.7 %) while 40 % of the notified cases were imported into the Czech Republic by foreigners. The period 1998-2004 for which the data on Czech tourism to other countries are available is characterized by increase in the absolute number of imported cases while the relative incidence of imported cases per 100,000 population traveling to other countries shows a downward trend. The highest numbers of cases were imported from Viet Nam (1,258 cases), Slovakia (1,155 cases) and India (786 cases). When considering Czech tourism to other countries for which the corresponding data are available, the highest rates of imported diseases in 1998-2004 were linked to the travels to Tunisia (1.18 imported cases per 1,000 tours), Bulgaria (0.69 per 1,000 tours) and Turkey (0.65 per 1,000 tours). The leading diagnosis of imported cases was salmonellosis (22%), followed by campylobacteriosis (10%) and trichuriasis (8%). Analysis of the Epidat information system databases for reporting transmissible diseases enables assessment of trends in imported infections in the Czech Republic as a point of departure for estimation of health risk from tourism and migration.

Although acne vulgaris is a common skin disorder, limited epidemiological data exist specifically for European populations. To determine the prevalence of self-reported acne among young people in Europe and evaluate the effect of lifestyle on acne. We conducted a cross-sectional population-based online survey in representative samples of individuals aged 15-24 years in Belgium, Czech and Slovak Republics, France, Italy, Poland and Spain (n = 10 521), identified by a quota sampling method based on age, geographic location and socio-professional category. The overall adjusted prevalence of self-reported acne was 57.8% (95% confidence interval 56.9% to 58.7%). The rates per country ranged from 42.2% in Poland to 73.5% in the Czech and Slovak Republics. The prevalence of acne was highest at age 15-17 years and decreased with age. On multivariate analysis, a history of maternal or paternal acne was associated with an increased probability of having acne (odds ratio 3.077, 95% CI 2.743 to 3.451, and 2.700, 95% CI 2.391 to 3.049, respectively; both P < 0.0001), as was the consumption of chocolate (OR 1.276, 95% CI 1.094 to 1.488, for quartile 4 vs. quartile 1). Increasing age (OR 0.728, 95% CI 0.639 to 0.830 for age 21-24 years vs. 15-17 years) and smoking tobacco (OR 0.705, 95% CI 0.616 to 0.807) were associated with a reduced probability of acne. The overall prevalence of self-reported acne was high in adolescents/young adults in the European countries investigated. Heredity was the main risk factor for developing acne. © 2017 European Academy of Dermatology and Venereology.

To get initial experience with alternative sampling (self-sampling) for HPV testing as the means of cervical cancer screening program. Original work. Institute of Molecular and Translational Medicine, Faculty of Medicine and Dentistry, Palacky University in Olomouc. Based on expression of interest, 215 self-sampling kits were posted to women. Evalyn(®) Brush Vaginal swabs obtained by self-sampling were analyzed for the presence of HPV infection by Cobas 4800 HPV (Roche) followed by genotyping using PapilloCheck(®) HPV-Screening (Greiner Bio-One). Sixty women randomly chosen from our sample were sent a questionnaire focused on their experience with self-sampling. One hundred seventy-four of 215 (81%) distributed self-sampling devices have been delivered to analysis. All cervicovaginal swabs were sampled correctly and it was possible to analyze them by Cobas 4800 HPV test. Similarly, 98% (171/174) samples were analyzable by PapilloCheck(®) HPV-Screening.One hundred twenty-five (72%) of 174 tested samples were HPV negative. Low risk HPV infection was detected only in 7 samples (4%), and high risk HPV (hrHPV) infection was present in 42 samples (24%). The most frequently detected hrHPV genotypes were HPV16 (11/42; 26%) and HPV53 (6/42; 14%). HrHPV co-infection was detected in 10 cases, in 5 of them lrHPV infection was find also.Of the 60 questionnaires, 48 (80%) were returned. From this group, 47 (98%) women rated their experience with self-sampling device as good to excellent. User manual of self-sampling device was considered good to excellent by all women (100%). All women also rated the convenience of self-sampling device using as good to excellent. As expected, most of the women (n = 42 [88%]) preferred self-sampling to physician sampling. Cervicovaginal self-sampling leads to valid results of HPV screening using two molecular genetics methods and was accepted by Czech women very well. The self-sampling as an opportunity to participate in cervical cancer screening could increase the attendance of the screening program and would help to reduce the incidence and mortality for this disease in the Czech population.

Opisthorchis viverrini is endemic in the South East Asian region, especially in Cambodia, Lao People's Democratic Republic, Vietnam and Thailand, but there have been no previous records from Myanmar. During stool surveys of rural populations in three regions of Lower Myanmar, Opisthorchis-like eggs were found in 34 out of 364 (9.3%) participants by stool microscopy after using the modified formalin-ether concentration technique. DNA was extracted from these positive stool samples and a portion of the mitochondrial cytochrome c oxidase subunit I (cox1) gene was amplified using the polymerase chain reaction and then sequenced. DNA sequences, successfully obtained from 18 of 34 positive samples (Bago Region, n = 13; Mon State, n = 3; Yangon Region, n = 2), confirmed that the eggs were of O. viverrini. Sequences showed 99.7% identity with O. viverrini mitochondrial cox1 (GenBank accession no. JF739555) but 95%, 88.7%, 82.6% and 81.4% identities with those of Opisthorchis lobatus from Lao People's Democratic Republic (GenBank accession nos. HQ328539-HQ328541), Metorchis orientalis from China (KT239342), Clonorchis sinensis from China (JF729303) and Opisthorchis felineus from Russia (EU921260), respectively. When alignement with other Opisthorchiidae trematodes, 81% similarity with Metorchis bilis from Czech Republic (GenBank accession nos. KT740966, KT740969, KT740970) and Slovakia (GenBank accession nos. KT740971-KT740973), 84.6% similarity with Metorchis xanthosomus from Czech Republic (GenBank accession no. KT740974), 78.6% similarity with M. xanthosomus from Poland (GenBank accession no. KT740968) and 82.2% similarity with Euamphimerus pancreaticus from Czech Republic (GenBank accession no. KT740975) were revealed. This study demonstrated, for the first time, O. viverrini from rural people in Myanmar using molecular methods and is an urgent call for surveillance and control activities against opisthorchiasis in Myanmar.

The (137)Cs specific activities (mean 32Bq kg(-1)) were determined in spruce bark samples that had been collected at 192 sampling plots throughout the Czech Republic in 1995, and were related to the sampling year. The (137)Cs specific activities in spruce bark correlated significantly with the (137)Cs depositions in areas affected by different precipitation sums operating at the time of the Chernobyl fallout in 1986. The ratio of the (137)Cs specific activities in bark and of the (137)Cs deposition levels yielded bark aggregated transfer factor T(ag) about 10.5×10(-3)m(-2)kg(-1). Taking into account the residual specific activities of (137)Cs in bark 20Bq kg(-1) and the available pre-Chernobyl data on the (137)Cs deposition loads on the soil surface in the Czech Republic, the real aggregated transfer factor after and before the Chernobyl fallout proved to be T*(ag)=3.3×10(-3)m(-2)kg(-1) and T**(ag)=4.0×10(-3)m(-2)kg(-1), respectively. The aggregated transfer factors T*(ag) for (137)Cs and spruce bark did not differ significantly in areas unequally affected by the (137)Cs fallout in the Czech Republic in 1986, and the figures for these aggregated transfer factors were very similar to the mean bark T(ag) values published from the extensively affected areas near Chernobyl. The magnitude of the (137)Cs aggregated transfer factors for spruce bark for the pre-Chernobyl and post-Chernobyl period in the Czech Republic was also very similar. The variability in spruce bark acidity caused by the operation of local anthropogenic air pollution sources did not significantly influence the accumulation and retention of (137)Cs in spruce bark. Increasing elevation of the bark sampling plots had a significant effect on raising the remaining (137)Cs specific activities in bark in areas affected by precipitation at the time when the plumes crossed, because the sums of this precipitation increased with elevation (covariable).

The purpose of the study was to describe the occurrence of the most common complaints related to MSDs in Czech dentists and to assess the risk factors affecting them. A questionnaire survey of 581 Czech dentists (the response rate 72.6%) was conducted in 2011. The questionnaire ascertained general information about the respondents, their work habits and environment along with the occurrence of musculoskeletal disorders. The respondents filled out the questionnaires during the educational events organized by the Czech Dental Chamber. At least mild difficulties associated with the motoric system were reported by 96.9% of the respondents, with 66.3% of respondents reporting moderate or major difficulties. Back and neck pain followed by shoulder pain and headache were the most common complaints in our sample. According to our data: age, gender, length of practice, a history of serious MSDs, the occurrence of MSDs in blood relatives, the perception of work as psychologically demanding, and especially a perceived moderate/bad general health were significantly associated with the four most common musculoskeletal complaints. Some of the factors were found as protective. This study suggests that MSDs represent a significant burden for Czech dentists and further research is needed to elucidate this issue.

The aim of this study was to determine the predictive validity of the Braden, Norton, and Waterlow scales in 2 long-term care departments in the Czech Republic. Assessing the risk for developing pressure ulcers is the first step in their prevention. At present, many scales are used in clinical practice, but most of them have not been properly validated yet (for example, the Modified Norton Scale in the Czech Republic). In the Czech Republic, only the Braden Scale has been validated so far. This is a prospective comparative instrument testing study. A random sample of 123 patients was recruited. The predictive validity of the pressure ulcer risk assessment scales was evaluated based on sensitivity, specificity, positive and negative predictive values, and the area under the receiver operating characteristic curve. The data were collected from April to August 2014. In the present study, the best predictive validity values were observed for the Norton Scale, followed by the Braden Scale and the Waterlow Scale, in that order. We recommended that the above 3 pressure ulcer risk assessment scales continue to be evaluated in the Czech clinical setting. © 2016 John Wiley & Sons Australia, Ltd.

Previously, it has been reported that mutations in the genes encoding for adipokines may be associated with impaired food intake and may serve as potential obesity biomarkers. The aim of this study was to investigate the possible associations of defined variability in leptin, leptin receptor, adiponectin, proopiomelanocortin and ghrelin genes with food preferences in the obese and non-obese Czech population and evaluate their potential as the obesity susceptibility genes. Using PCR followed by restriction analysis, we studied 185 volunteers. Basic anthropometrical characteristics associated to obesity were measured and the food intake was monitored using a 7-day record method. In the group of obese individuals, a subset of 34 morbidly obese patients was studied for plasma leptin and soluble leptin receptor levels. None of the examined polymorphisms was associated to anthropometrical or demographic characteristics of the study subjects. The Gln223Arg polymorphism within the leptin receptor gene was significantly associated with lower plasma leptin levels (the RR genotype being more frequent in patients with lower plasma leptin levels; P = 0.001). No associations of the examined polymorphisms with food preferences was observed. Based on our results, the examined polymorphisms in the adipokine genes do not seem to be the major risk factor for obesity development in the Czech population nor significantly affect food preferences.

To perform multiple-locus variable number tandem repeat analysis (MLVA) of B. pertussis strains from the collection of the National Reference Laboratory for Diphtheria and Pertussis (NRL/DIPE), National Institute of Public Health (NIPH), Prague. The study strains were isolated from clinical specimens collected mostly in the Czech Republic over a nearly 50-year period from 1967 to 2015 (June). The isolates from three periods characterized by different vaccination strategies and trends in pertussis are compared for genetic diversity and distribution of MLVA types (MT). Based on the results obtained, the suitability for use of MLVA in the analysis of epidemic outbreaks of B. pertussis in the Czech Republic is considered. DNA samples extracted from B. pertussis strains included in the present study were examined by MLVA using the standard protocol. Data were processed by means of the eBURST algorithm and the calculation of the Simpson diversity index (DI) was used for the statistical analysis. Data were analyzed as a whole and also separately for strains from the three periods: 1967-1980, 1990-2007, and 2008-2015 (June). Fourteen different MT were detected in the study strains, with three of them not being reported before. The most common MTs were MT27 and MT29. MT29 was predominant in 1967-1980 while MT27 was the most prevalent in 1990-2007 and 2008-2015 (June). The DI was the lowest (0.49) in 2008-2015 (June), and comparably higher DIs were calculated for the two previous periods (i.e. 0.667 for 1967-1980 and 0.654 for 1990-2007). MLVA revealed a decrease in genetic diversity and shifts in MT distribution of B. pertussis strains isolated from clinical specimens in the Czech Republic from 1967 to 2015 (June). These shifts in the Czech Republic can be characterized as a progressive increase in global MTs at the expense of the locally unique ones. The most common MT, similarly to other geographical areas with long-term high vaccination coverage, is MT27. The results of MLVA of 136 B. pertussis strains can provide a background for using this method in molecular epidemiological analysis of smaller groups of strains.

The enamelin gene (ENAM) polymorphism (rs12640848) was recently associated with dental caries in primary teeth in Polish children. The aims of the present study were to prove this association in primary dentition and to find a possible effect of this variant on caries development in permanent dentition in Czech children. This study comprised 905 Czech children. Totally, 187 children aged 2-6 years with primary dentition [78 healthy subjects (with decayed/missing/filled teeth, dmft = 0) and 109 patients with early childhood caries (ECC; dmft ≥ 1)] were included in this case-control study. In addition, 177 subjects aged 13-15 years without caries (DMFT = 0) and 541 children with dental caries (DMFT ≥ 1) in permanent dentition were selected from the ELSPAC study. Genotype determination of the ENAM polymorphism (rs12640848) was based on the TaqMan method. No significant differences in the allele or genotype frequencies between the caries-free children and those affected by dental caries were observed in both primary and permanent dentitions. Lack of association between the ENAM polymorphism (rs12640848) and dental caries in Czech children was detected. Although ENAM is considered as a candidate gene for dental caries, the presence of the ENAM variant (rs12640848) cannot be used as a risk factor of this multifactorial disease in the Czech population.

Retinopathy of Prematurity (ROP) is a potentially serious condition that can afflict preterm infants. Timely and correct identification of individuals at risk of developing a serious form of ROP is therefore of paramount importance. WinROP is an online system for predicting ROP based on birth weight and weight increments. However, the results vary significantly for various populations. It has not been evaluated in the Czech population. This study evaluates the test characteristics (specificity, sensitivity, positive and negative predictive values) of the WinROP system in Czech preterm infants. Data on 445 prematurely born infants included in the ROP screening program at the University Hospital Ostrava, Czech Republic, were retrospectively entered into the WinROP system and the outcomes of the WinROP and regular screening were compared. All 24 infants who developed high-risk (Type 1 or Type 2) ROP were correctly identified by the system. The sensitivity and negative predictive values for this group were 100%. However, the specificity and positive predictive values were substantially lower, resulting in a large number of false positives. Extending the analysis to low risk ROP, the system did not provide such reliable results. The system is a valuable tool for identifying infants who are not likely to develop high-risk ROP and this could help to substantially reduce the number of preterm infants in need of regular ROP screening. It is not suitable for predicting the development of less serious forms of ROP which is however in accordance with the declared aims of the WinROP system.

In the present study, an allele-specific primer-polymerase chain reaction (ASP-PCR) for genotyping a single nucleotide polymorphism (SNP) of swine Toll-like receptor 5 (TLR5) (C1205T; P402L) that is related to the impaired recognition of Salmonella enterica serovar Choleraesuis (SC) was developed. The allele frequencies in several pig breeds in Japan and the Czech Republic were also compared. The swine TLR5 C1205T mutation was successfully determined by ASP-PCR using genomic DNA samples in Japan that had previously been genotyped by a sequencing method. Using the PCR condition determined, genomic DNA samples from blood obtained from 110 pigs from seven different breeds in the Czech Republic were genotyped by the ASP-PCR. The genotyping results from the ASP-PCR completely matched the results from the sequencing method. The allele frequency of the swine TLR5 C1205T mutation was 27.5% in the Landrace breed of the Czech Republic compared with 50.0% in Japanese Landrace. In Japan, the C1205T mutation was found only in the Landrace breed, whereas in the Czech Republic it was found in both the Landrace and Piétrain breeds. These results indicate the usefulness of ASP-PCR for detecting a specific SNP for swine TLR5 affecting ligand recognition. They also suggest the possibility of genetically improving pigs to enhance their resistance against SC infection by eliminating or selecting this specific SNP of swine TLR5. © 2012 The Societies and Blackwell Publishing Asia Pty Ltd.

In 1999, a group of Kosovars arrived in Hamilton, Ontario, with a coordinated international pre-migration plan, as part of the United Nations Humanitarian Evacuation Program. Since 1997, a substantial number of Roma refugees from the Czech Republic also arrived in Hamilton, with no special pre-migration planning. This study examined whether the organized settlement efforts led to better adaptation and perceived health for the Kosovars, using the Czech Roma as a comparison group. Adult members of 50 Kosovar (n=157 individuals) and 50 Czech Roma (n=76 individuals) randomly selected families completed a questionnaire on sociodemographics, health, well-being, and perceived adaptation to Canada. Differences between groups were examined using univariate and multivariate analyses. Comparison was made to the Ontario population where possible. There were more Kosovars than Czech Roma over the age of 50 (22.1% vs 10.5%, p=0.03). Nearly one quarter (21.7%) of the Kosovars had a score indicating post-traumatic stress disorder (PTSD) on the Harvard Trauma Questionnaire (HTQ), compared to none of the Roma (p<0.001). After adjustment for age and PTSD, the Kosovars were significantly more likely to report fair or poor adaptation to Canada (OR=10.5, 95% CI=3.6-31.2) and that life is somewhat or very stressful (OR=3.9, 95% CI=2.1-7.4). Differences for other measures were no longer significant after adjustment. The health and adaptation of the Kosovars was not better than that of the Czech Roma. Reasons for this finding may include differences in demographics, the presence of PTSD, and differing length of time since arrival in Canada.

Since 1991 a human biomonitoring network has been established in the Czech Republic as part of the Environmental Health Monitoring System, which was set out by the Government Resolution. During the last quarter-century, important data was obtained to characterize exposure to both children and adult populations to significant toxic substances from the environment, to development trends over time, to establish reference values and compare them with existing health-related values. Moreover, the saturation of population with several essential substances as selenium, zinc, copper or iodine has also been monitored. Development of analytical and statistical methods led to increase the capacity building, improvement of QA/QC in analytical laboratories and interpretation of results. The obtained results are translated to policy actions and are used in health risk assessment processes at local and national levels. Copyright © 2016 Elsevier GmbH. All rights reserved.

While commercial jewellery glass beads offer the basis of novel radiotherapy TL dosimetry (Jafari et al. 2014a,b,c, 2015a,b), detailed study of TL variation is required for the products from various manufacturers. Investigation is made for glass beads from four manufacturers from four countries: China (Rocaille), Japan (Mill Hill), Indonesia (TOHO™) and Czech Republic (Czech). Sample composition was determined using an energy-dispersive X-ray unit coupled to a scanning electron microscope. Values of mass attenuation coefficient, μ/ρ, as a function of photon energy were then calculated for photons of energy 1 keV to 10 MeV, using the National Institute of Standards and Technology XCOM program. Radiation and energy response were determined using X-rays generated at accelerating potentials from 80 kVp to 6 MV (TPR20/10=0.670). All bead types showed TL to be linear with dose (R2>0.999). Glow curve dosimetric peaks reached a maximum value at 300 °C for the Toho and 290 °C for the Czech and Mill Hill products but was between 200-250 °C for the Rocaille product. Radiation sensitivity following mass normalisation varied within an order of magnitude; Toho samples showed the greatest and Rocaille the least sensitivity. For the Toho, Czech, Rocaille and Mill Hill samples the energy responses at 80 kVp were 5.0, 4.0, 3.6 and 3.3 times that obtained at 6 MV. All four glass bead types offer potential use as TL dosimeters over doses commonly applied in radiotherapy. Energy response variation was <1% at 6 MV but significant variation was found for photon beam energies covering the kV range; careful characterisation is required if use at this range is intended.

The aim of the study was to assess the association between promoter polymorphism [A(-596)G] in interleukin-6 gene and office systolic and diastolic blood pressures, and the heart rate (HR) in apparently healthy Czech subjects. Furthermore, we evaluated the possible influence of gender, BMI and smoking on these supposed associations. An age-matched (40-50 years) and gender-matched (F/M=81/89) sample of apparently healthy Czech subjects (n=170, F/M=81/89) without hypertension, other cardiovascular diseases or diabetes was examined. The A(-596)G Il-6 gene polymorphism was detected by the PCR method. No differences in genotype distribution and/or allelic frequency was found between groups with lower systolic blood pressure (Ł 122 mm Hg) and higher systolic blood pressure (> 122 mm Hg). Similarly, no differences in the IL-6 polymorphism were found between lower (Ł 86 mm Hg) and higher (> 86 mm Hg) diastolic blood pressure groups. However, we proved a significant increase of genotypes AG+GG as well as the allele (-596)G in higher (>78 beats/min) heart rate group. The genotypes AG+GG represent significantly higher relative risk for higher HR frequency, especially in women. Among lean persons with a low heart rate frequency, fewer AG+GG genotypes were determined than among any other subjects. The genotypes AG+GG are more frequent in non-smoking persons with higher HR compared to non-smoking subjects with lower HR, especially in women. Gender, BMI and smoking substantially modify the distribution of A(-596)G Il-6 gene polymorphism in apparently healthy persons with lower or higher heart rate.

Several genetic polymorphisms influence the risk of heavy alcohol consumption but it is not well understood whether the genetic effects are similar in different populations and drinking cultures, nor whether the genetic influences on binge drinking are similar to those seen for alcoholism. We have analyzed the effect of the Arg47His (rs1229984) variant within the alcohol dehydrogenase (ADH1B) gene on a range of drinking related variables in a large Eastern European Slavic population (Czech HAPIEE study), which recruited random samples of men and women aged 45-69 years in 7 Czech towns (3,016 males and 3,481 females with complete data). Drinking frequency, annual alcohol intake, prevalence of binge drinking (≥100 g in men and ≥60 g in women at least once a month) and the mean dose of alcohol per occasion were measured by the graduated frequency questionnaire. Alcohol intake in a typical week was used to define heavy drinking (≥350 g/wk in men and ≥210 g in women). Problem drinking (≥2 positive answers on CAGE) and negative consequences of drinking on different aspects of life were also measured. The frequency of the His47 allele carriers was 11%. Homozygotes in the common allele (Arg47Arg), among both males and females, had significantly higher drinking frequency, and annual and weekly intake of alcohol than His47 carriers. The odds ratio of heavy drinking in Arg47Arg homozygotes versus His47 carriers was 2.1 (95% confidence intervals 1.1-3.2) in men and 2.2 (1.0-4.7) in women. In females, but not in males, Arg47Arg homozygotes had marginally significantly higher prevalence of binge drinking and mean alcohol dose per drinking session. There was no consistent association with problem drinking and negative consequences of drinking. The ADH1B genotype was associated with the frequency and volume of drinking but its associations with binge drinking and problem drinking were less consistent.

In 1956-1958, excavations of Pod Hradem Cave in Moravia (eastern Czech Republic) revealed evidence for human activity during the Middle-Upper Paleolithic transition. This spanned 25,050-44,800 cal BP and contained artefacts attributed to the Aurignacian and Szeletian cultures, including those made from porcelanite (rarely used at Moravian Paleolithic sites). Coarse grained excavation techniques and major inversions in radiocarbon dates meant that site chronology could not be established adequately. This paper documents re-excavation of Pod Hradem in 2011-2012. A comprehensive AMS dating program using ultrafiltration and ABOx-SC pre-treatments provides new insights into human occupation at Pod Hradem Cave. Fine-grained excavation reveals sedimentary units spanning approximately 20,000 years of the Early Upper Paleolithic and late Middle Paleolithic periods, thus making it the first archaeological cave site in the Czech Republic with such a sedimentary and archaeological record. Recent excavation confirms infrequent human visitation, including during the Early Aurignacian by people who brought with them portable art objects that have no parallel in the Czech Republic. Raw material diversity of lithics suggests long-distance imports and ephemeral visits by highly mobile populations throughout the EUP period. Copyright © 2017 Elsevier Ltd. All rights reserved.

Background Over the last five decades, a wide gap in mortality opened between western and eastern Europe; this gap increased further after the dramatic fluctuations in mortality in the former Soviet Union (FSU) in the 1990s. Recent rapid increases in mortality among lower socioeconomic groups in eastern Europe suggests that socioeconomic factors are powerful determinants of mortality in these populations but the more proximal factors linking the social conditions with health remain unclear. The HAPIEE (Health, Alcohol and Psychosocial factors In Eastern Europe) study is a prospective cohort study designed to investigate the effect of classical and non-conventional risk factors and social and psychosocial factors on cardiovascular and other non-communicable diseases in eastern Europe and the FSU. The main hypotheses of the HAPIEE study relate to the role of alcohol, nutrition and psychosocial factors. Methods and design The HAPIEE study comprises four cohorts in Russia, Poland, the Czech Republic and Lithuania; each consists of a random sample of men and women aged 45–69 years old at baseline, stratified by gender and 5 year age groups, and selected from population registers. The total planned sample size is 36,500 individuals. Baseline information from the Czech Republic, Russia and Poland was collected in 2002–2005 and includes data on health, lifestyle, diet (food frequency), socioeconomic circumstances and psychosocial factors. A short examination included measurement of anthropometric parameters, blood pressure, lung function and cognitive function, and a fasting venous blood sample. Re-examination of the cohorts in 2006–2008 focuses on healthy ageing and economic well-being using face-to-face computer assisted personal interviews. Recruitment of the Lithuanian cohort is ongoing, with baseline and re-examination data being collected simultaneously. All cohorts are being followed up for mortality and non-fatal cardiovascular events. Discussion The HAPIEE study will provide important new insights into social, behavioural and biological factors influencing mortality and cardiovascular risk in the region. PMID:17049075

Population-genetic comparison of the Sorbian isolate population in Germany with the German KORA population using genome-wide SNP arrays

PubMed Central

2011-01-01

Background The Sorbs are an ethnic minority in Germany with putative genetic isolation, making the population interesting for disease mapping. A sample of N = 977 Sorbs is currently analysed in several genome-wide meta-analyses. Since genetic differences between populations are a major confounding factor in genetic meta-analyses, we compare the Sorbs with the German outbred population of the KORA F3 study (N = 1644) and other publically available European HapMap populations by population genetic means. We also aim to separate effects of over-sampling of families in the Sorbs sample from effects of genetic isolation and compare the power of genetic association studies between the samples. Results The degree of relatedness was significantly higher in the Sorbs. Principal components analysis revealed a west to east clustering of KORA individuals born in Germany, KORA individuals born in Poland or Czech Republic, Half-Sorbs (less than four Sorbian grandparents) and Full-Sorbs. The Sorbs cluster is nearest to the cluster of KORA individuals born in Poland. The number of rare SNPs is significantly higher in the Sorbs sample. FST between KORA and Sorbs is an order of magnitude higher than between different regions in Germany. Compared to the other populations, Sorbs show a higher proportion of individuals with runs of homozygosity between 2.5 Mb and 5 Mb. Linkage disequilibrium (LD) at longer range is also slightly increased but this has no effect on the power of association studies. Oversampling of families in the Sorbs sample causes detectable bias regarding higher FST values and higher LD but the effect is an order of magnitude smaller than the observed differences between KORA and Sorbs. Relatedness in the Sorbs also influenced the power of uncorrected association analyses. Conclusions Sorbs show signs of genetic isolation which cannot be explained by over-sampling of relatives, but the effects are moderate in size. The Slavonic origin of the Sorbs is still genetically detectable. Regarding LD structure, a clear advantage for genome-wide association studies cannot be deduced. The significant amount of cryptic relatedness in the Sorbs sample results in inflated variances of Beta-estimators which should be considered in genetic association analyses. PMID:21798003

Relationship Between Subjectively Evaluated Health and Fear of Death Among Elderly in Three Cultural Contexts.

It is often argued that declining health in elderly people makes death more salient and threatening. However, we argue that health, optimism, and social support interact to predict fear of death in samples from Cameroon, the Czech Republic, and Germany. Low health was associated with enhanced fear of death for participants who received only little social support. As the measure of optimism did not comply with psychometric requirements in the Cameroonian sample, the three-way interaction was tested only in the Czech and German samples. It was found that the two-way interaction was further qualified by optimism in that low health was associated with enhanced fear of death for participants with little social support unless they reported pronounced optimism. Thus, internal and external resources, respectively, can serve to buffer the effect of declining health on the fear of death in the elderly.

From January 2011 to December 2013, a total of 262 samples, from 188 patients suspected of having syphilis were tested for the presence of treponemal DNA by PCR amplification of five chromosomal loci, including the polA (TP0105), tmpC (TP0319), TP0136, TP0548, and 23S rRNA genes. Altogether, 146 samples from 103 patients were PCR positive for treponemal DNA. A set of 81 samples from 62 PCR-positive patients were typeable, and among them, nine different genotypes were identified. Compared to a previous study in the Czech Republic during 2004 to 2010, the number of genotypes detected among syphilis patients in a particular year increased to six in both 2012 and 2013, although they were not the same six. The proportion of macrolide-resistant clinical isolates in this 3-year study was 66.7%. PMID:25100820

Tobacco is the largest cause of morbidity and mortality. The aim of this study is to analyse several health and economically related indicators of tobacco consumption: smoking prevalence, standardized death rates (SDRs) from lung cancer and the proportion of GDP spent on tobacco in Croatia and other transitional countries--the Czech Republic, Slovakia, Poland, Hungary, Slovenia, Romania, and Bulgaria. The overall smoking prevalence in Croatia decreased by 5.2% during 1994-2005, more among females (-9.9%) than males (-0.3%). There is no significant difference in the smoking prevalence between Croatia (27.4%) and other countries. However, 33.8% of Croatian males smoked during 2002-2005, more than in Romania and the Czech Republic, and less than in Hungary and Poland. The prevalence of female smoking (21.7%) in Croatia is similar to the female smoking prevalence in Poland, the Czech Republic, and Hungary, but male smoking is predominant in all countries. The proportion of smokers among youth is above 20% and it is the highest in the Czech Republic (29.7%), followed by Hungary (26.7%), Slovenia (24.9%), Croatia (24.1%), and Poland (21.5%). The proportion of smokers among girls is higher than among boys in Slovenia, Hungary, the Czech Republic, and Croatia, contrary to Slovakia, Bulgaria, and Poland where boys smoke slightly more. There is no significant difference between the prevalence of smoking among girls in Croatia and Bulgaria, Poland, the Czech Republic, Hungary, Slovenia, and Slovakia. According to the SDR from lung cancer in males (70.3/100,000), Croatia is ranked high assuming the 3rd place, after Hungary (99.7) and Poland (72.0). With a SDR of 15.9/100,000 for females, Croatia is ranked slightly better--5th place. Tobacco consumption continues to be a major public health problem in transitional countries. Croatia conducted several campaigns and programmes in the past. However, results reveal that current anti-tobacco strategies are ineffective in reducing the smoking prevalence among men and youth. Men do not smoke less than a decade ago and, despite the observed decline among women, increasing trends are observed among teenage girls. Croatia should apply a comprehensive approach that would include raising awareness of health risks, restriction of smoking in public places, higher taxing, implementing stricter bans on advertising and promotion of tobacco as well as supporting smoking cessation. This last measure is believed to bring about some results in the medium term in targeted population groups, provided that it is supported by all health professionals. Otherwise, we may expect progress at the population level in the field of social stigmatization of smoking and wider intolerance to second-hand smoke. The full impact of smoking on the population health is yet to be seen and in the future it will undoubtedly remain one of the major contributors to the poor public health situation in Croatia.

Dietary guidelines in the Czech Republic. II.: Nutritional profiles of food groups.

PubMed

Brázdová, Z; Fiala, J; Bauerová, J; Mullerová, D

2000-11-01

Modern dietary guidelines set in terms of food groups are easy to use and understand for target populations, but rather complicated from the point of view of quantification, i.e. the correctly set number of recommended servings in different population groups according to age, sex, physical activity and physiological status on the basis of required intake of energy and individual nutrients. It is the use of abstract comprehensive food groups that makes it impossible to use a simple database of food tables based on the content of nutrients in individual foods, rather than their groups. Using groups requires that their nutritional profiles be established, i.e. that an average content of nutrients and energy for individual groups be calculated. To calculate nutritional profiles for Czech dietary guidelines, the authors used three different methods: (1) Simple profiles, with all commodities with significant representation in the Czech food basket represented in equal amounts. (2) Profiles based on typical servings, with the same commodities as in (1) but in characteristic intake quantities (typical servings). (3) Food basket-based profiles with commodities constituting the Czech food basket in quantities identical for that basket. The results showed significant differences in profiles calculated by different methods. Calculated nutrient intakes were particularly influenced by the size of typical servings and it is therefore essential that a realistic size of servings be used in calculations. The consistent use of recommended food items throughout all food groups and subgroups is very important. The number of servings of foods from the five food groups is not enough if a suitable food item is not chosen within individual groups. On the basis of their findings, the authors fully recommend the use of nutritional profiles based on typical servings that give a realistic idea of the probable energy and nutrient content in the recommended daily intake. In view of regional cultural differences, national nutritional profiles play a vital importance. Population studies investigating the size of the typical servings and the most frequently occurring commodities in the food basket should be made every three years. Nutritional profiles designed in this way constitute an important starting point for setting national dietary guidelines, their implementation and revisions.

The prevention of patient falls is one of the safety goals set forth by the Ministry of Health of the Czech Republic. A sociological survey was carried out to (1) determine to what extent nurses identify the risk of patient falls at admission, (2) if the risk is reassessed and at what intervals, (3) what preventive measures were taken, and (4) in what way are patient falls reported. A representative sample consisting of general nurses working shifts on inpatient wards at hospitals in the Czech Republic was surveyed. Altogether 772 nurses took part in the study. The survey showed that at admission, most nurses assessed the risk of falls (91.6%). Nonetheless, it should stand as a stark warning that nearly one fifth of the respondents (16.2%) did not reassess the risk of falls after admission! On the other hand, it can be perceived as a positive that most nurses (70.1%) use a multifaceted program of preventive measures for at risk patients and immediately reported fall events to the doctor in charge (71.4%). During statistical testing, the predication that a working atmosphere supporting a culture of patient safety would significantly decrease the probability of patient falls and increases the willingness of nurses to use preventive programs in daily practice. Results from the survey showed that a system to minimalize fall risks has been successfully introduced into the hospitals of the Czech Republic. The system is based on the recommendations of the Ministry of Health of the Czech Republic.

Birch pollen grains are known to be ice nucleating active biological particles. The ice nucleating activity has previously been tracked down to biological macromolecules that can be easily extracted from the pollen grains in water. In the present study, we investigated the immersion freezing behavior of these ice nucleating active (INA) macromolecules. Therefore we measured the frozen fractions of particles generated from birch pollen washing water as a function of temperature at the Leipzig Aerosol Cloud Interaction Simulator (LACIS). Two different birch pollen samples were considered, with one originating from Sweden and one from the Czech Republic. For the Czech and Swedish birch pollen samples, freezing was observed to start at -19 and -17 °C, respectively. The fraction of frozen droplets increased for both samples down to -24 °C. Further cooling did not increase the frozen fractions any more. Instead, a plateau formed at frozen fractions below 1. This fact could be used to determine the amount of INA macromolecules in the droplets examined here, which in turn allowed for the determination of nucleation rates for single INA macromolecules. The main differences between the Swedish birch pollen and the Czech birch pollen were obvious in the temperature range between -17 and -24 °C. In this range, a second plateau region could be seen for Swedish birch pollen. As we assume INA macromolecules to be the reason for the ice nucleation, we concluded that birch pollen is able to produce at least two different types of INA macromolecules. We were able to derive parameterizations for the heterogeneous nucleation rates for both INA macromolecule types, using two different methods: a simple exponential fit and the Soccer ball model. With these parameterization methods we were able to describe the ice nucleation behavior of single INA macromolecules from both the Czech and the Swedish birch pollen.

Attempts to solve the problem of high-level waste disposal including the spent fuel from nuclear power plants have been made in the Czech Republic for over the 10 years. Already in 1991 the Ministry of Environment entitled The Czech Geological Survey to deal with the siting of the locality for HLW disposal and the project No. 3308 ''The geological research of the safe disposal of high level waste'' had started. Within this project a sub-project ''A selection of perspective HLW disposal sites in the Bohemian Massif'' has been elaborated and 27 prospective areas were identified in the Czech Republic. Thismore » selection has been later narrowed to 8 areas which are recently studied in more detail. As a parallel research activity with siting a granitic body Melechov Massif in Central Moldanubian Pluton has been chosen as a test site and the 1st stage of research i.e. evaluation and study of its geological, hydrogeological, geophysical, tectonic and structural properties has been already completed. The Melechov Massif was selected as a test site after the recommendation of WATRP (Waste Management Assessment and Technical Review Programme) mission of IAEA (1993) because it represents an area analogous with the host geological environment for the future HLW and spent fuel disposal in the Czech Republic, i.e. variscan granitoids. It is necessary to say that this site would not be in a locality where the deep repository will be built, although it is a site suitable for oriented research for the sampling and collection of descriptive data using up to date and advanced scientific methods. The Czech Republic HLW and spent fuel disposal programme is now based on The Concept of Radioactive Waste and Spent Nuclear Fuel Management (''Concept'' hereinafter) which has been prepared in compliance with energy policy approved by Government Decree No. 50 of 12th January 2000 and approved by the Government in May 2002. Preparation of the Concept was required, amongst other reasons in connection with preparations for the Czech Republic's accession to the European Union and in connection with the Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management adopted under the auspices of the International Atomic Energy Agency, which was signed by the Czech Republic in 1997. According to the approved Concept it is expected that a deep geological repository in the Czech Republic will be built in granitic rocks.« less

RNF213/Mysterin has been identified as a susceptibility gene for moyamoya disease, a cerebrovascular disease characterized by occlusive lesions in the circle of Willis. The p.R4810K (rs112735431) variant is a founder polymorphism that is strongly associated with moyamoya disease in East Asia. Many non-p.R4810K rare variants of RNF213 have been identified in white moyamoya disease patients, although the ethnic mutations have not been investigated in this population. In the present study, we screened for RNF213 variants in 19 Slovakian and Czech moyamoya disease patients. A total of 69 RNF213 coding exons were directly sequenced in 18 probands and one relative who suffered from moyamoya disease in Slovakia and the Czech Republic. We previously reported one proband harboring RNF213 p.D4013N. Results from the present study identified four rare variants other than p.D4013N (p.R4019C, p.E4042K, p.V4146A, and p.W4677L) in four of the patients. P.V4146A was determined to be a novel de novo mutation, and p.R4019C and p.E4042K were identified as double mutations inherited on the same allele. P.W4677L, found in two moyamoya disease patients and an unaffected subject in the same pedigree, was a rare single nucleotide polymorphism. Functional analysis showed that RNF213 p.D4013N, p.R4019C and p.V4146A-transfected human umbilical vein endothelial cells displayed significant lowered migration, and RNF213 p.V4146A significantly reduced tube formation, indicating that these are disease-causing mutations. Results from the present study identified RNF213 rare variants in 22.2% (4/18 probands) of Slovakian and Czech moyamoya disease patients, confirming that RNF213 may also be a major causative gene in a relative large population of white patients.

Volcanic and geochemical evolution of the Carboniferous Teplice Rhyolite, Central-European Variscides (Germany and Czech Republic)

2017-04-01

The Altenberg-Teplice Volcanic Complex (ATVC; 325 Ma) represents one of the earliest magmatic centers of the Late- to Post-tectonic period of the Variscan orogeny in Central Europe. The ca. 35×18 km ATVC is located in the Erzgebirge/Krušné hory (Germany/Czech Republic) and hosts two principal extrusive units: (1) an initial volcanosedimentary succession preserved in the Schönfeld-Altenberg Depression Complex (Walther et al., in press) and (2) a thick volcanic pile produced during the peak eruptive stage, known as the Teplice Rhyolite (TR). The TR represents mainly a caldera-fill sequence (Benek, 1991), whose volcanic and geochemical evolution has not been fully defined. Seven petrotypes have been mapped in the TR on the Czech side (Jiránek et al., 1987). To the north, on German territory, Lobin (1986) distinguished eight petrotypes. The TR is dominated by thick sheets of welded and non-welded crystal clast-rich (< 45 %) ignimbrites, which are intercalated with rhyolitic lava-dome complexes. The ATVC has been intruded by late high-volume granite porphyritic melts and several plutons associated, in parts, with Sn-, Li mineralization. Two important drillings expose over 600 m of TR volcanics. Samples from (1) the Mi-4 borehole (Mikulov, Czech Republic) have been geochemically evaluated and a vertical reverse chemical zoning (Zr, Rb) was identified and interpreted in terms of a continuous eruption (Breiter et al., 2001). In (2) the well 2112-87 near Schmiedeberg in Germany, ignimbrites are separated by two rhyolitic, lithophysae-bearing lava units, suggesting a multistage caldera evolution. In the South of the ATVC out- and subcrops reveal a caldera outflow facies. In Czech Republic, ignimbrites prevail with a single belt of late-stage rhyolitic lavas on the eastern margin. We present sixty new whole-rock and mineral chemical data (biotite) to define the geochemical evolution, the composition and the chemical character of the TR rocks. Currently, Nd-Sr isotopes are being measured on whole-rock samples; U/Pb dating and chemical composition of TR zircons are planned. In this binational project, for the first time detailed facies and geochemical analyses are being combined in order to reconstruct the volcanic evolution and magma genesis of the ATVC.

Furthermore, to analyze reported cases of occupational TB and to compare the incidence and sex-specific and age-specific prevalence with the data reported in the Czech Republic. Data on the number of employees at risk of exposure to occupational TB were derived from the Automated Risk Classification System of the Slovak Republic. Data on cases of occupational TB were taken from health statistics (Institute of Health Information and Statistics/National Health Information Center in the Slovak Republic and the National Institute of Public Health in the Czech Republic). A retrospective analysis was conducted (for 1998-2012) of reported cases of occupational TB, selected from Article 24 of the List of occupational diseases (infectious and parasitic diseases except tropical infectious and parasitic diseases and diseases transmissible from animals to humans). The selection criterion was a TB diagnosis according to ICD-10. In the Czech Republic, the data were derived from Article 5.1.02 (tuberculosis), Chapter V. of the List of Occupational Diseases. The data obtained were analyzed by methods of descriptive statistics. The numbers of employees with a level III risk of exposure to occupational TB in the Slovak Republic declined by 30% over the 15 years of study and by 40% in category Q. In 2012, 2027 employees were classified in category III and 1442 of them belonged to group Q. Females accounted for 81-84% of employees at risk of exposure to occupational TB. Eighty-six and 181 cases of occupational TB were reported in the Slovak Republic and in the Czech Republic, respectively, in 1998-2012, with the incidence showing a downward trend in both countries. TB of the respiratory tract was reported most often (83.7% of the total of reported cases of occupational TB). As expected, more cases occurred in females than in males (1.9 times as many cases in females as in males in the Slovak Republic and three times as many cases in females as in males in the Czech Republic). The incidence of occupational TB was the highest in sector Q, with the highest absolute numbers reported in nurses. In 2012, the incidence rates of occupational TB were 0.22 cases per 100,000 sick benefit policy holders in the Slovak Republic and 0.13 cases per 100,000 sick benefit policy holders in the Czech Republic. The incidence of occupational TB has a downward trend in both countries, similarly to TB incidence in the general population. A negative aspect in both countries is the incidence of occupational TB at the middle productive age, in contrast to the population occupationally non-exposed to TB. Slovakia is surrounded by higher prevalence countries, with the exception of the Czech Republic. It cannot be ruled out that, in addition to the known factors influencing the prevalence of TB, including occupational TB, migration from eastern countries, including job search migration, can also play a role in increase in TB cases. It is vital to continue epidemiological surveillance and to reduce the risk of TB as much as possible also in healthcare settings by adhering to barrier nursing practices. Cases of active TB need early and adequately long, controlled treatment in order to reduce, among others, the incidence of multi-drug resistant TB.

This article deals with the possibilities of population management of invasive and in Czech Republic no - native species Helianthus tuberosus. We have chosen study areas in Poodri PLA, it is located near the industrial city Ostrava (Moravian-Silesian region). Invasive Helianthus tuberosus forms monodominant vegetation, excludes the original and often rare plant species and reduces biodiversity. It is a risk for the further development of the landscape of Poodri PLA. There is no known effective way to dispose of invasive Helianthus tuberosus so far. We have applied the proposed management works on 15 monitoring areas and then evaluated their effectiveness. We have used chemical (herbicides) and mechanical (mowing, digging up) methods and their combinations. The most effective was the combination of 3 interventions: manual mowing - spraying - mowing by mechanization, just mowing itself rather promotes the spread of the population. We can say this is a pilot study from a long-term project dealing with the effectiveness of different ways of invasive plants management.

Distributions of spin/shape parameters of asteroid families and targeted photometry by ProjectSoft robotic observatory

In our recent work (Hanus et al. 2013) we studied dynamics of asteroid families constrained by the distribution of pole latitudes vs semimajor axis. The model contained the following ingredients: (i) the Yarkovsky semimajor-axis drift, (ii) secular spin evolution due to the YORP effect, (iii) collisional reorientations, (iv) a simple treatment of spin-orbit resonances and (v) of mass shedding.We suggest to use a different complementary approach, based on distribution functions of shape parameters. Based on ~1000 old and new convex-hull shape models, we construct the distributions of suitable quantities (ellipticity, normalized facet areas, etc.) and we discuss differences among asteroid populations. We also check for outlier points which may then serve as a possible identification of (large) interlopers among "real" family members.This has also implications for SPH models of asteroid disruptions which can be possibly further constrained by the shape models of resulting fragments. Up to now, the observed size-frequency distribution and velocity field were used as constraints, sometimes allowing for a removal of interlopers (Michel et al. 2011).We also describe ongoing observations by the ProjectSoft robotic observatory called "Blue Eye 600", which supports our efforts to complete the sample of shapes for a substantial fraction of (large) family members. Dense photometry is targeted in such a way to maximize a possibility to derive a new pole/shape model.Other possible applications of the observatory include: (i) fast resolved observations of fireballs (thanks to a fast-motion capability, up to 90 degrees/second), or (ii) an automatic survey of a particular population of objects (MBAs, NEAs, variable stars, novae etc.)Acknowledgements: This work was supported by the Technology Agency of the Czech Republic (grant no.

The SCORE scale predicts the 10-year risk of fatal atherosclerotic cardiovascular disease (CVD), based on conventional risk factors. The high-risk version of SCORE is recommended for Central and Eastern Europe and former Soviet Union (CEE/FSU), due to high CVD mortality rates in these countries. Given the pronounced social gradient in cardiovascular mortality in the region, it is important to consider social factors in the CVD risk prediction. We investigated whether adding education and marital status to SCORE benefits its prognostic performance in two sets of population-based CEE/FSU cohorts. The WHO MONICA (MONItoring of trends and determinants in CArdiovascular disease) cohorts from the Czech Republic, Poland (Warsaw and Tarnobrzeg), Lithuania (Kaunas), and Russia (Novosibirsk) were followed from the mid-1980s (577 atherosclerotic CVD deaths among 14,969 participants with non-missing data). The HAPIEE (Health, Alcohol, and Psychosocial factors In Eastern Europe) study follows Czech, Polish (Krakow), and Russian (Novosibirsk) cohorts from 2002-05 (395 atherosclerotic CVD deaths in 19,900 individuals with non-missing data). In MONICA and HAPIEE, the high-risk SCORE ≥5% at baseline strongly and significantly predicted fatal CVD both before and after adjustment for education and marital status. After controlling for SCORE, lower education and non-married status were significantly associated with CVD mortality in some samples. SCORE extension by these additional risk factors only slightly improved indices of calibration and discrimination (integrated discrimination improvement <5% in men and ≤1% in women). Extending SCORE by education and marital status failed to substantially improve its prognostic performance in population-based CEE/FSU cohorts.

Background Gene polymorphisms encoding the enzyme NADPH–cytochrome P450 oxidoreductase (POR) contribute to inter-individual differences in drug response. Aim To estimate polymorphic allele frequencies of the POR gene in a Czech Slavic population. Materials & Methods The gene POR was analyzed in 322 Czech Slavic individuals from a control cohort by sequencing and HRM analysis. Results Twenty-five SNP genetic variations were identified. Of these variants, 7 were new, unreported SNPs, including two SNPs in the 5´flanking region (g.4965 C>T and g.4994 G>T), one intronic variant (c.1899 −20C>T), one synonymous SNP (p.20Ala=) and three nonsynonymous SNPs (p.Thr29Ser, p.Pro384Leu and p.Thr529Met). The p.Pro384Leu variant exhibited reduced enzymatic activities compared to wild type. Conclusion New POR variant identification indicates that the number of uncommon variants might be specific for each subpopulation being investigated, particularly germane to the singular role that POR plays in providing reducing equivalents to all CYPs in the endoplasmic reticulum.

Toxoplasma gondii, Neospora caninum, and Encephalitozoon cuniculi are important infectious agents, with T. gondii and E. cuniculi having zoonotic potential. There are two main clonal lineages (types I and II) of T. gondii in Europe, but little is known about genotypes of T. gondii in wild animals. The aim of our study was molecular detection of these three pathogens in tissues of wild red foxes ( Vulpes vulpes) from the Czech Republic. Using PCR (B1 gene), we detected T. gondii in 10% of the animals that we tested ( n=100); N. caninum and E. cuniculi were not detected. The T. gondii samples were genotyped by single multiplex PCR assay with 15 microsatellite markers. Five samples were successfully genotyped as genotype II, a unique finding for T. gondii isolated from red foxes from the Czech Republic.

In the Central European context, the 9th and 10th centuries are well known for rapid cultural and societal changes concerning the development of the economic and political structures of states as well as the adoption of Christianity. A bioarchaeological study based on a subadult skeletal series was conducted to tackle the impact of these changes on infant and young child feeding practices and, consequently, their health in both urban and rural populations. Data on growth and frequency of nonspecific stress indicators of a subadult group aged 0-6 years were analyzed. A subsample of 41 individuals was selected for nitrogen and carbon isotope analyses, applying an intra-individual sampling strategy (bone vs. tooth). The isotopic results attest to a mosaic of food behaviors. In the urban sample, some children may have been weaned during their second year of life, while some others may have still been consuming breast milk substantially up to 4-5 years of age. By contrast, data from the rural sample show more homogeneity, with a gradual cessation of breastfeeding starting after the age of 2 years. Several factors are suggested which may have been responsible for applied weaning strategies. There is no evidence that observed weaning strategies affected the level of biological stress which the urban subadult population had to face compared with the rural subadult population. © 2014 Wiley Periodicals, Inc.

Generally, rodents and other small mammals are considered as one of the sources of Toxoplasma gondii or Neospora caninum infection for cats and dogs as the definitive hosts of these two parasites, respectively. The aim of the study was to find out the prevalence of these two parasites in wild small mammals from the Czech Republic and to characterize T. gondii isolates by methods of molecular biology. A total of 621 wild small mammals were caught in the Czech Republic during years 2002-2014. Antibodies to T. gondii were detected by latex agglutination test in six (2.5%) of 240 small mammals (in two A. agrarius and four A. flavicollis). Antibodies to N. caninum were detected by commercially available competitive-inhibition enzyme-linked immunosorbent assay in one A. flavicolis (0.4%). Three of 427 (0.7%) liver samples were positive for T. gondii by PCR while negative for N. caninum. All embryo samples (n=102) were negative for both T. gondii and N. caninum. The three liver samples positive for T. gondii DNA (two from A. flavicollis and one from A. sylvaticus) were genotyped by 15 microsatellite markers and characterized as type II. To our knowledge, this is the first information about genetic characterization of T. gondii isolates in small mammals from Europe and the first detection of N. caninum antibodies in wild rodents from the Czech Republic.

This study is a continuation of our preceding research identifying suitable environmental samples for the tracing of atmospheric pollution in industrial areas. Three additional types of environmental samples were used to characterise contamination sources in the industrial area of Ostrava city, Czech Republic. The region is known for its extensive metallurgical and mining activities. Fingerprinting of stable Pb isotopes was applied to distinguish individual sources of anthropogenic Pb. A wide range of 206 Pb/ 207 Pb ratios was observed in the investigated samples: 206 Pb/ 207 Pb = 1.168-1.198 in mosses; 206 Pb/ 207 Pb = 1.167-1.215 in soils and 206 Pb/ 207 Pb = 1.158-1.184 in tree cores. Black and brown coal combustion, as well as metallurgical activities, is the two main sources of pollution in the area. Fossil fuel burning in industry and households seems to be a stronger source of Pb emissions than from the metallurgical industry. Concentration analyses of tree rings showed that a significant increase in As concentrations occurred between 1999 and 2016 (from 0.38 mg kg -1 to 13.8 mg kg -1 ). This shift corresponds to the use of brown coal from Bílina, Czech Republic, with an increased As concentration. The burning of low-quality fuels in households remains a problem in the area, as small ground sources have a greater influence on the air quality than do industrial sources.

Although the research on cyberbullying has increased dramatically in recent years, still little is known about how cyberbullying participant groups (i.e., cyberbullies, cybervictims, and cyberbully-victims) differ from one another. This study aims to discriminate between these groups at an individual and relational level by controlling for age and gender. Self-control, offline aggression, and self-esteem are analyzed as individual-level variables. Parental attachment and peer rejection are involved as relational-level variables. A total of 2,092 Czech adolescents aged 12 to 18 were enrolled from a random sample of 34 primary and secondary schools located in the South Moravian region of the Czech Republic. Discriminant function analyses indicated that the participant groups are discriminated by two functions. The first function increases the separation between cyberbullies and cyberbully-victims from cybervictims, indicating that cyberbullies and cyberbully-victims are similar to each other in terms of low self-control, offline aggression, and gender, and have higher scores on measures of low self-esteem and offline aggression. However, cyberbully-victims had the highest scores on these measures. The second function discriminates between all three groups, which indicates that those variables included in the second function (i.e., parental attachment, peer rejection, self-esteem, and age) distinguish all three involved groups. © The Author(s) 2014.

This study was conducted to evaluate the prevalence of antibodies against Borrelia bugdorferi (Bb) s.l. and tick-borne encephalitis virus (TBEV) in zoo animals in the Czech Republic. We collected 133 serum samples from 69 animal species from 5 zoos located in different parts of the country. The samples were obtained from even-toed ungulates (n=78; 42 species), odd-toed ungulates (n=32; 11 species), carnivores (n=13; 9 species), primates (n=2, 2 species), birds (n=3; 2 species), and reptiles (n=5; 3 species). A high antibody prevalence (60%) was observed for Bb s.l. On the other hand, only two animals had TBEV-specific antibodies: a markhor (Capra falconeri) and a reindeer (Rangifer tarandus), both from the same zoo, located in an area endemic for TBEV. Both of these animals were also positive for Bb s.l. antibodies. Our results indicate that a high number of animal species in the Czech zoos were exposed to Bb s.l. and that TBEV infection occurred at least in one of the investigated zoos. Considering the pathogenic potential of these two tick-borne pathogens, clinical and serological monitoring should be continued, and therapeutic and preventive measures should be taken when necessary.

Climate conditions exert significant influence over the the population dynamic, life cycle duration, infestation pressure and the overall occurrence of majority of agricultural pests and diseases. Particularly in the case of those pest species whose development is directly linked with the climate conditions the shift of their climatic niche or their infestation capability is to be expected under the changing climate. Te presented study is focused on the most important potato pest i.e Colorado potato beetle (Leptinotarsa decemlineata, Say 1824) and most important pest of grain maize i.e. European corn borer (Ostrinia nubilalis, Hübner 1796). Simulations of potential distribution of pests in the Czech Republic in the conditions of climate change were made with the usage of dynamical model CLIMEX and by the interpolation of output EI from 43 locations there are climate conditions of almost whole area of the Czech Republic considered as favorable for pest' survival. The models validation was based on the comparison of the modeled potential pests' distribution with the field observations in the current climate conditions. Under the expected climate conditions the pests will most likely be able to complete their development earlier and in higher population densities. Both mechanisms might cause a subsequent increase of the severity of the pest infestation. In addition to this the higher temperature and its earlier coming in the beginning of the vegetative season may support the mobility and faster local spread of some species. The estimates of the future climate is based on the assumption of slow increase of green house gases emissions and low climate sensitivity to their rising concentration (LOW B1) as well as the "opposite" scenario assuming rapid growth of emissions and the high sensitivity of the climate system (HIGH A2). Three GCM models that were driven by these emission scenarios included HadCM3, NCAR-PCM and ECHAM4. For Colorado potato beetle the realization of HIGH A2 in combination with HadCM3 means almost the half of the arable land endangered by the occurrence of bivoltine population by 2025. The same model indicates for 2050 this area increasing by 72 %. According to ECHAM A2 2050 is the occurrence of partial third generation likely in the 45 % of arable land and completed third generation in the 0.2 % of arable land. The results show that climate will be a significant factor determining the development and survival of the European corn borer. According to the presented models estimations the area of the univoltine population establishment could be through the next 20 - 30 years significantly larger and till 2050 it could cover most of the agriculturally suitable land in the Czech Republic. The threat of the ECB bivoltine population expansion in the next decade is not immediate but is likely between 2025 - 2050 at least in the warmest areas in the Czech Republic. There is the apparent risk of the increasing damage caused by pests due to the shifts in the climate conditions. It should be stressed that the study is based on so called potential distribution which means the expected geographical distribution of the given species is based only on the climate conditions regardless of any other factors determining the species abundance or distribution.

A large survey carried out from June to September 2002 in the territory of the Czech Republic found and analyzed the knowledge of the population of the Czech Republic in relation to self-medication and o-t-c drugs and revealed the main problematic areas from the viewpoint of the public. The survey was particularly focused on the behaviour of people in relation to packaging of OTC drugs and drug information sheets, expiration period of medicaments-advertisements for OTC drugs in the media, most frequently selected indications for self-medication, self-medication in small children, financial participation in self-medication and the resultant compliance or non-compliance, and the price of the OTC drug and dosage. The results show that 68% of respondents are able to take a medicine after its expiration period. An o-t-c drug would be bought just on the basis of television advertising by 7% of respondents, and more than a half of the respondents (57%) stated they would first consult their physician or pharmacist. In the case of a sudden ailment of a one-year-old child, 80% of respondents stated that they would contact the physician, 8% opted for self-medication. Under the assumption that an OTC drug is covered by health insurance, 27% of respondents would go to the physician, though they could buy it themselves.

Healthcare system and the wealth-health gradient: a comparative study of older populations in six countries.

The present study provides a comparative analysis of the association between wealth and health in six healthcare systems (Sweden, the United Kingdom, Germany, the Czech Republic, Israel, the United States). National samples of individuals fifty years and over reveal considerable cross-country variations in health outcomes. In all six countries wealth and health are positively associated. The findings also show that state-based healthcare systems produce better population health outcomes than private-based healthcare systems. The results indicate that in five out of the six countries studied, the wealth-health gradients were remarkably similar, despite significant variations in healthcare system type. Only in the United States was the association between wealth and health substantially different from, and much greater than that in the other five countries. The findings suggest that private-based healthcare system in the U.S. is likely to promote stronger positive associations between wealth and health. Copyright © 2014 Elsevier Ltd.

Ontogenetic and intraspecific variation in the late Emsian - Eifelian (Devonian) conodonts Polygnathus serotinus and P. bultyncki in the Prague Basin (Czech Republic) and Nevada (western U.S.). Acta Geologica Polonica, 63 (2), 153-174, Warszawa. Samples from populations of Polygnathus serotinus Telford 1975 and P. bultyncki Weddige 1977 from the Prague Basin and Nevada display normal variation for Devonian conodont species. A considerable number of previous authors, however, have proposed unnecessary synonyms of these two species, primarily because they have not recognized ontogenetic variation. In contrast, we interpret the variation as ontogenetic as well as intraspecific and present detailed synonymies as a result. A third species, P. praetrigonicus Bardashev 1992, which has been carried in open nomenclature for many years, is an important indicator of the basal costatus Zone in the Prague Basin, New York, and Nevada. We review the stratigraphic distribution of these three species and the conodont zonation across the Emsian-Eifelian (Lower-Middle Devonian) boundary. Polygnathus pseudocostatus sp. nov. (partitus-costatus zones, central Nevada) is described herein. We have observed a decrease in the pit size during ontogeny in P. bultyncki although we have not measured enough specimens to rule out intraspecific versus ontogenetic variation.

While terrestrial moss and other plants are frequently used for environmental mapping and monitoring projects, data on the regional geochemistry of humus are scarce. Humus, however, has a much larger life span than any plant material. It can be seen as the "environmental memory" of an area for at least the last 60-100 years. Here concentrations of 39 elements determined by ICP-MS and ICP AES, pH and ash content are presented for 259 samples of forest floor humus collected at an average sample density of 1 site/300 km2 in the Czech Republic. The scale of anomalies linked to known contamination sources (e.g., lignite mining and burning, metallurgical industry, coal fired power plants, metal smelters) is documented and discussed versus natural processes influencing humus quality. Most maps indicate a local impact from individual contamination sources: often more detailed sampling than used here would be needed to differentiate between likely sources.

The COPHES/DEMOCOPHES twin project was performed in 2011-2012 in 17 European countries to harmonize all steps of the human biomonitoring survey. Urinary cadmium, cotinine, phthalate metabolites, and hair mercury were measured in children (N = 120, 6-11 years) and their mothers of reproductive age, living in urban or rural areas. Cadmium in mothers' and children's urine was detected at a geometric mean (GM) concentration 0.227 and 0.109 μg/L, respectively; 95th percentile (P95) was 0.655 and 0.280 μg/L in mothers and children, respectively. No age-related, education-related, or urban versus rural differences were observed within the frame of each population group. Cadmium urinary level in mothers was about twofold compared with children. Higher levels were obtained in all smoking mothers but not in occasionally smoking or mothers and children exposed to environmental tobacco smoke (ETS). Mercury values in mothers were significantly higher in urban than in rural populations but not in children. GM and P95 for mercury in children's hair were 0.098 and 0.439 μg/g and in mothers' hair were 0.155 and 0.570 μg/g. Concentrations for mercury in the Czech samples were lower than European average. Hair mercury increased significantly with consumption of fish or seafood and with number of amalgam tooth fillings (in children). A positive association was found with family educational level. No influence of age was observed. Urinary cadmium and hair mercury levels were lower than health-based guidelines with one exception. High levels of urinary cotinine were found in the 12 smoking mothers (GM approximately 500 μg/L); lower levels in occasionally smoking mothers, N = 11 (34.5 μg/L). The mean cotinine levels in nonsmoking mothers who reported daily exposure to ETS was 10.7 μg/L. A similar mean value (10.8 μg/L) was obtained in six children who had daily exposure to ETS. In children without exposure to ETS, the mean cotinine level was 1.39 μg/L urine. Cotinine in the urine of children demonstrates limited protection of the Czech children against exposure to ETS.

To survey obesity prevention methods for use in the Roma population with a focus on eating behaviors. A semi-structured interview was used to identify potentially useful obesity prevention methods. Basic anthropometric measurements were also gathered at the same time. This study was part of the "Obesity and overweight in the Roma minority in the Region of South Bohemia" research project (grant project 280-COST-LD14114). Participants consisted of members of the Roma minority (302 respondents) as well as the majority (Czech) population for comparisons. Differences in eating behaviors like irregular eating schedules and excessive consumption of fast food were observed. Statistically significant differences between the Roma minority and the majority (Czech/non-Roma) population were found in this area with the help of statistical significance tests. The Chi-square characteristic of independence (χ2) was, in case of this distribution, valued at 30.815 with 5 degrees of freedom, P < 0.001. The analyses, based on the second degree of classification, identified statistically significant differences between the Roma minority and the majority population. Members of the Roma minority attended preventive health check-ups statistically less often than members of the majority population. Differences between the majority and the Roma population were also found in the degree of patient cooperation with general practitioners. The results show that the Roma population is more likely to engage in eating behaviors that can contribute to overweight and obesity than the majority population. Based on the results of a semi-structured interview and on the results of anthropometric measurements, we can say that the Roma population is at a greater health risk, relative to overweight and obesity, than the majority population.

Aim A collaborative exercise with several institutes was organized by the Forensic DNA Service (FDNAS) and the Institute of the Legal Medicine, 2nd Faculty of Medicine, Charles University in Prague, Czech Republic, with the aim to test performance of different laboratories carrying out DNA analysis of relatively old bone samples. Methods Eighteen laboratories participating in the collaborative exercise were asked to perform DNA typing of two samples of bone powder. Two bone samples provided by the National Museum and the Institute of Archaelogy in Prague, Czech Republic, came from archeological excavations and were estimated to be approximately 150 and 400 years old. The methods of genetic characterization including autosomal, gonosomal, and mitochondrial markers was selected solely at the discretion of the participating laboratory. Results Although the participating laboratories used different extraction and amplification strategies, concordant results were obtained from the relatively intact 150 years old bone sample. Typing was more problematic with the analysis of the 400 years old bone sample due to poorer quality. Conclusion The laboratories performing identification DNA analysis of bone and teeth samples should regularly test their ability to correctly perform DNA-based identification on bone samples containing degraded DNA and potential inhibitors and demonstrate that risk of contamination is minimized.

Bullying in school is a public health concern which continues to be a serious threat to physical and emotional health of children and adolescents. The purpose of this study is to examine trends in bullying behaviour among school-aged children in the Czech Republic. Data were obtained from cross-sectional self-report surveys in the years 1994-2014 as a part of the Health Behaviour in School-aged Children study (HBSC) from a representative sample of 11-, 13-, and 15-year olds. The highest proportion of children who bullied others (20-47%) occurred during the years 1994 and 1998. The logistic regression models showed significant decreasing trends in bullying others and also in being bullied, regardless of age and gender. The decreasing trend in bullying may be the consequence of a preventive policy in the Czech Republic, but also a change in the understanding of the concept of bullying in society.

Zafeiriou, Eleni; Sofios, Spyros; Partalidou, Xanthi

2017-06-01

The present work examines the intertemporal causal relationship between environmental damage from carbon emissions released by agriculture per 1000 ha of utilized agriculture area and economic performance in the sector of agriculture as described by net value added per capita. The autoregressive distributed lag bounds testing approach is employed to examine this linkage, for three new entrant EU countries, namely, Bulgaria, Czech Republic, and Hungary. The environmental Kuznets hypothesis is confirmed in the long run for Bulgaria and Czech Republic while in the short run is validated only for the case of Czech Republic. The results indicate that the adoption of environment-friendly farming practices and crops' selection does not secure simultaneous high economic and environmental performance at least in the short run for our sample countries and also in the long run for Hungary necessitating the modification of the agro-environmental measures adopted to make those two targets complementary and not mutually exclusive for a farmer.

1996-01-01

Sexual development and behavior of 771 Czech girls 16 to 18 years old had been investigated by two sexuologists during the period of 1986 till 1994. A standardized interview of 78 items had been applied in a setting of a rehabilitation facility in Franzensbad. The majority of probands were there for rehabilitation after appendectomy. There were 389 examinees (158 apprentices and 231 students) interviewed before "the velvet revolution" and 382 girls (159 apprentices and 223 students) in the course of the years 1990 to 1994. A comparison of these two groups revealed a definite change in the psychosexual development of girls in the Czech society after the "Velvet Revolution". Particularly the motivation for the first coitus had changed. After November 1989 it was noticed that the answer "obliged her partner" had significantly decreased and the answer "wished it for myself" has substantially increased. Also in the group of probands with multiple sexual partners (21.5% of the sample) their average number decreased unexpectedly after "the Velvet Revolution".

In order to determine the actual prevalence of avian influenza viruses (AIV) in wild birds in the Czech Republic extensive surveillance was carried out between January and April 2006. A total of 2101 samples representing 61 bird species were examined for the presence of influenza A by using PCR, sequencing and cultivation on chicken embryos. AIV subtype H5N1 was detected in 12 Mute swans (Cygnus olor). The viruses were determined as HPAI (highly pathogenic avian influenza) and the hemagglutinin sequence was closely similar to A/mallard/Italy/835/06 and A/turkey/Turkey/1194/05. Following the first H5N1 case, about 300 wild birds representing 33 species were collected from the outbreak region and tested for the presence of AIV without any positive result. This is the first report of highly pathogenic avian influenza subtype H5N1 in the Czech Republic. The potential role of swan as an effective vector of avian influenza virus is also discussed.

Until recently, three spirochete genospecies were considered to be the causative agents of Lyme borreliosis (LB) in Europe: Borrelia burgdorferi sensu stricto, Borrelia afzelii and Borrelia garinii. However, the DNA of Borrelia valaisiana, Borrelia lusitaniae, Borrelia spielmanii and Borrelia bissettii has already been detected in samples of human origin, or the spirochetes were isolated from the patients with symptoms of LB. Molecular analysis of 12 selected serum samples collected in the regional hospital confirmed the presence of B. bissettii DNA in cases of single and multiple infection in patients with symptomatic borreliosis or chronic borrelial infection. The presence of B. bissettii as a single strain in patients provides strong support of the fact that B. bissettii might be a causative agent of the disease. After the first isolation of B. bissettii from the samples of human origin in Slovenia, following the detection of this species in cardiac valve tissue of the patient with endocarditis and aortic valve stenosis in the Czech Republic, here we present additional molecular data supporting the involvement of B. bissettii in LB in Europe.

Do sudden air temperature and pressure changes affect cardiovascular morbidity and mortality?

Plavcová, E.; Davídkovová, H.; Kyselý, J.

2012-04-01

Previous studies have shown that sudden changes in weather (usually represented by air temperature and/or pressure) are associated with increases in daily mortality. Little is understood about physiological mechanisms responsible for the impacts of weather changes on mortality, and whether similar patterns appear for morbidity as well. Relatively little is known also about differences in the magnitude of the mortality response in provincial regions and in cities, where the impacts may be exacerbated by air pollution effects and/or heat island. The present study examines the effects of sudden air temperature and pressure changes on morbidity (represented by hospital admissions) and mortality due to cardiovascular diseases in the population of the Czech Republic (approx. 10 million inhabitants) and separately in the city of Prague (1.2 million inhabitants). The events are selected from data covering 1994-2009 using the methodology introduced by Plavcová and Kyselý (2010), and they are compared with the datasets on hospital admissions and daily mortality (both standardized to account for long-term changes and the seasonal and weekly cycles). Relative deviations of morbidity/mortality from the baseline were averaged over the selected events for days D-2 (2 days before a change) up to D+7 (7 days after), and their statistical significance was tested by means of the Monte Carlo method. The study aims at (i) identifying those weather changes associated with increased cardiovascular morbidity/mortality, separately in summer and winter, (ii) comparing the effects of weather changes on morbidity and mortality, (iii) identifying whether urban population of Prague is more/less vulnerable in comparison to the population of the whole Czech Republic, (iv) comparing the effects for different cardiovascular diseases (ischaemic heart diseases, ICD-10 codes I20-I25; cerebrovascular diseases, I60-I69; hypertension, I10; atherosclerosis, I70) and individual population groups (by age and gender), and (v) identifying physiological mechanisms which play roles in deteriorating health conditions of vulnerable population groups.

Stroke treatment is time-dependent, yet no study has systematically examined response to individual stroke symptoms in the general population. This nationwide study identifies which specific factors prompt correct response (calling 911) to stroke. Between November and December of 2005, a survey using a 3-stage random-sampling method including area, household, and household member sampling was conducted throughout the Czech Republic. Participants >40 years old were personally interviewed via a structured and standardized questionnaire concerning general knowledge and correct response to stroke as assessed by the Stroke Action Test (STAT). Predictors of scoring >50% on STAT were identified by multiple regression. A total of 650 households were contacted, yielding 592 interviews (response rate 91%). Mean age was 58+/-12, 55% women. Sixty-nine percent thought stroke was serious condition, and 57% thought it could be treated. Also 54% correctly named >/=2 risk factors, and 46% named >/=2 warning signs. Eighteen percent of respondents scored >50% on STAT. The predictors of such a score were age (for each 10-year increment, OR 1.4, 95% CI 1.2 to 1.7), secondary school education (OR 1.7, 95% CI 1.1 to 2.6), knowing that stroke is a serious disease (OR 1.8, 95% CI 1.1 to 3.1), and knowing that stroke is treatable (OR 2.0, 95% CI 1.2 to 3.2). Knowledge about stroke in the Czech Republic was fair, yet response to warning signs was poor. Our study is the first to identify that calling 911 was influenced by knowledge that stroke is a serious and treatable disease and not by recognition of symptoms.

This paper deals with the analysis of the costs, applied, for example, when treating specific diseases – an important aid in prioritizing the process of resource allocation. In our review, the specific disease is dementia caused by Alzheimer’s disease. This paper aims to provide more information on the partial costs per patient that are calculated according to the aggregated data from publicly available sources as well as from the results of authors’ own investigation. The University Hospital in Hradec Králové and the General Health Insurance Company of the Czech Republic participated in this research. The elementary research objective was to compare the costs per patient diagnosed early onset, to those of the patient diagnosed later. The Czech Republic lacks information regarding dementia. Therefore, these issues require attention. The methods used in this paper included time series analyses, methods of direct questioning, interviews with experts, and analyses of medical documentation. These methods were combined to exploit their particular advantages and to ensure the issues discussed, were covered. The investigation showed that the underpinning of patients with Alzheimer’s disease at early onset is advantageous from an economic perspective, because the cost of outpatient care is much lower compared with that of inpatient care. The international comparisons of the volume of care provided should be approached with great caution. These are based solely on the facts of various expert estimates and are not usually supported by hard data. Yet, they still illustrate the overall view of our ability to take care of people with dementia. According to experts, care in the Czech Republic significantly lags behind the rest of developed Europe. While services are provided to 26% of people with dementia in Germany and 50% in France, the experts estimate that services are provided to only 10% of the population in the Czech Republic. If we were to offer a similar volume of services in the Czech Republic, to the same extent as the average in Europe, we would have to triple the existing capacities. PMID:26396519

The proportion of occupational infectious diseases (ID) in the total number of occupational diseases reported in the Slovak Republic (SR) and the Czech Republic (CR) was decreasing from 1973 to 2010. Our study presents a longitudinal analysis of the occurrence of occupational infectious diseases in the Slovak Republic and the Czech Republic in the period from 1973-2010 with special focus on viral hepatitis. The sources of data were national health statistics of Czechoslovakia, the Czech Republic and the Slovak Republic. Descriptive statistical methods were used for data analysis. Incidence rate of reported diseases was calculated per 100,000 general population or per 100,000 people insured. During the studied period, a total of 2,931 and 8,318 cases of occupational viral hepatitis (VH) were reported in the Slovak Republic and the Czech Republic, respectively. The incidence culminated in the late 1970s when hepatitis represented almost 50% of all reported occupational infectious diseases. Most cases of occupational hepatitis occurred in health and social services. Since the early 1980s, a steep decrease in the incidence of hepatitis has been observed due to the gradual implementation of mandatory vaccination against hepatitis A and B in risk groups. In SR in 1973, the incidence rate of occupational infectious diseases and that of occupational viral hepatitis was 10.85/100,000 and 1.86/100,000, respectively. In 2010, these rates decreased to 0.74/100,000 and 0.20/100,000, respectively. In CR, the incidence rates of occupational infectious diseases and that of occupational viral hepatitis reported in 1973 were 11.75/100,000 and 3.69/100,000. In 2010, reported incidence rates were 1.71/100,000 and 0.10/100,000, respectively. Although the incidence of occupational viral hepatitis has dramatically decreased in the Slovak and the Czech Republic as well as in other Visegrad group countries during the studied period, we emphasize the necessity of continuing epidemiological surveillance of hepatitis, especially with regard to the recent incidence increase of viral hepatitis C.

The main aim of this study was to determine and evaluate urinary excretion of uranium in the general public of the Czech Republic. This value should serve as a baseline for distinguishing possible increase in uranium content in population living near legacy sites of mining and processing uranium ores and also to help to distinguish the proportion of the uranium content in urine among uranium miners resulting from inhaled dust. The geometric mean of the uranium concentration in urine of 74 inhabitants of the Czech Republic was 0.091 mBq/L (7.4 ng/L) with the 95% confidence interval 0.071-0.12 mBq/L (5.7-9.6 ng/L) respectively. The geometric mean of the daily excretion was 0.15 mBq/d (12.4 ng/d) with the 95% confidence interval 0.12-0.20 mBq/d (9.5-16.1 ng/d) respectively. Despite the legacy of uranium mines and plants processing uranium ore in the Czech Republic, the levels of uranium in urine and therefore, also human body content of uranium, is similar to other countries, esp. Germany, Slovenia and USA. Significant difference in the daily urinary excretion of uranium was found between individuals using public supply and private water wells as a source of drinking water. Age dependence of daily urinary excretion of uranium was not found. Mean values and their range are comparable to other countries, esp. Germany, Slovenia and USA. Copyright © 2015 Elsevier Ltd.

A rather fast and complicated progression of an infection caused by some strains of Staphylococcus aureus could be associated with the expression and co-action of virulence factor complexes in these strains. This study screened the antibiotic susceptibility and prevalence of virulence markers in isolates of meticillin-resistant S. aureus (MRSA) obtained from patients hospitalized at the University Hospital in Olomouc, Czech Republic. A total of 100 isolates was screened for 13 genes encoding extracellular virulence determinants (tst, pvl, eta, etb, sea, seb, sec, sed, see, seg, seh, sei and sej) and for their distribution in sample types. Eighty-nine isolates were positive for at least one of the genes. Genes for etb, pvl, see and seh were not detected in any of the MRSA isolates. No statistically significant differences in the occurrence of the determinants studied among sample types were found.

Residues of printing ink components were determined in 94 samples of packaging materials commercially used in the Czech Republic for food packaging. The samples tested included printed polyethylene and polypropylene films, co-extruded and laminated films, paperboard beverages boxes, foils for thermo sealing of polystyrene cups, and polypropylene cups. Printing ink components were extracted with diethylether, then separated and determined using gas chromatography-mass spectrometry (GC/MS). Fifty compounds potentially originating from printing were isolated, identified and quantified. No acute health risk for consumers were identified, even though several findings of high levels of photo-initiators (e.g. in polyethylene terephthalate (PET) films for thermo sealing of polystyrene cups) as well as plasticizers (acetyl tributyl citrate, tributyl aconitate, 2-butoxyethyl oleate and 2-ethylhexyl diphenyl phosphate in co-extruded films) indicate that their real migration into food and/or food simulants needs to be undertaken for a proper safety evaluation.

Chigger mites were collected from 1,080 wild birds of 37 species at Certak (Czech Republic), in the western Carpathian Mountains, from 29 July to 24 September 2005. The prevalence of infestation with chigger larvae was 7%. A total of 325 chigger specimens from 10 bird species was identified and three chigger species were found: Neotrombicula autumnalis, N. carpathica, and N. inopinata, the latter two species being reported on new hosts. Neotrombicula carpathica is reported in the Czech Republic for the first time. A total of 509 chigger larvae found on 79 host specimens were examined by polymerase chain reaction (PCR) for the presence of Borrelia burgdorferi s.l. DNA (fragments of the rrf (5S)--rrl (23S) intergenic spacer), and Anaplasma phagocytophilum DNA (epank1 gene). A fragment of specific Borrelia DNA was amplified through PCR in one sample, and the PCR product was further analyzed by reverse line blotting assay, whereby both genospecies of B. garinii and B. valaisiana were proved. This sample pooled five chigger larvae collected from one Sylvia atricapilla on 11 August 2005. No A. phagocytophilum DNA was amplified. We conclude that larvae of the genus Neotrombicula can be infected with Borrelia genospecies originated from their present or former hosts.

While numerous ancient human DNA datasets from across Europe have been published till date, modern-day Poland in particular, remains uninvestigated. Besides application in the reconstruction of continent-wide human history, data from this region would also contribute towards our understanding of the history of the Slavs, whose origin is hypothesized to be in East or Central Europe. Here, we present the first population-scale ancient human DNA study from the region of modern-day Poland by establishing mitochondrial DNA profiles for 23 samples dated to 200 BC – 500 AD (Roman Iron Age) and for 20 samples dated to 1000–1400 AD (Medieval Age). Our results show that mitochondrial DNA sequences from both periods belong to haplogroups that are characteristic of contemporary West Eurasia. Haplotype sharing analysis indicates that majority of the ancient haplotypes are widespread in some modern Europeans, including Poles. Notably, the Roman Iron Age samples share more rare haplotypes with Central and Northeast Europeans, whereas the Medieval Age samples share more rare haplotypes with East-Central and South-East Europeans, primarily Slavic populations. Our data demonstrates genetic continuity of certain matrilineages (H5a1 and N1a1a2) in the area of present-day Poland from at least the Roman Iron Age until present. As such, the maternal gene pool of present-day Poles, Czechs and Slovaks, categorized as Western Slavs, is likely to have descended from inhabitants of East-Central Europe during the Roman Iron Age.

There are numerous indications for stabilization using instrumentation of the upper cervical spine. This area is comprised of sophisticated anatomy. There is no study describing bony and vascular anomalies of this area in the middle European population. The main aim of this study was to investigate prevalence of any vertebral artery (VA) variations and osseous anomalies in the region of the craniocervical junction in a large sample of Czech patients based on three-dimensional computed tomographic angiography (3D CTA). The VA has a variable course through C2 before it passes above its groove on the posterior arch of C1. The artery can course more medially, more posteriorly or more superiorly, thus limiting the diameter of the bony elements used as landmarks for the safe insertion of metalwork. This is known as a high-riding VA (HRVA). The VA was considered HRVA in this study if the thickness of the C2 isthmus was less than 5 mm and/or the C2 internal height was less than 2 mm and/or the width of the C2 pedicle was less than 4 mm. The prevalence of ponticulus posticus (PP) was also identified. Following the VA variations in the V3 segment of the artery were persistent first intersegmental artery (FIA), fenestration (FEN) of the VA, and the posterior inferior cerebellar artery (PICA) branch originating from the C1/2 part of VA. Records of 511 patients from our institution were analyzed. The mean age of the patients was 63.6 years. One hundred and twenty-three (24.1 %) patients were identified to have HRVA, 30 (6 %) present on both sides. The age of patient over 70 years and female sex were found to be significant risk factors for HRVA presence. The prevalence of a nearby PICA branch was 4 %, FIA was 0.4 %, and FEN was 0.2 %. The presence of PP was identified in 14.3 % of patients. The HRVA and PP are common anomalies in the Czech population, and routine preoperative high-resolution CT evaluation is mandatory to prevent the VA injury when C1-C2 instrumentation is planned. The female sex and age over 70 years were found to be the most important factors for HRVA presence. The FIA and the FEN VA were rare in our study contrary to reports published from Asia, showing as many as a 10 % the VA presence over the starting point for C1 lateral screw. On the basis of the infrequent occurrence of these anomalies, we do not recommend routine CT angiography when upper cervical spine instrumentation in the normal population is planned.

Curing over-use by prescribing fees: an evaluation of the effect of user fees’ implementation on healthcare use in the Czech Republic

2015-01-01

In 2008, the Czech Republic instituted a new policy that requires most patients to pay a small fee for some inpatient and outpatient healthcare services. Using the Survey of Health Aging and Retirement in Europe, this article examines the changes in healthcare utilization of Czechs 50 years and older following the new fee requirement by constructing difference-in-differences regression models focusing on four outcome measures: any visits to primary care physician, any hospitalization, number of visits to the primary care physician and number of nights hospitalized. For this population, I find that the likelihood of having any primary care visit decreased after the policy was instituted. The likelihood of reporting any hospitalization was not significantly changed. The predicted number of primary care visits per person declined, but the predicted number of nights spent in a hospital did not. I find only mixed evidence of greater effect of the user fees on some subpopulations compared with others. Those 65 or older reduced their use more than those between 50 and 64, and so did those who consider their health to be good, and the less educated. PMID:24790063

The purpose of this national survey was to determine current anesthesia practices for cesarean delivery in the Czech Republic. In November 2011, we invited all departments of obstetric anesthesia in the Czech Republic to participate in a prospective study to monitor consecutive peripartum obstetric anesthesia procedures. Data were recorded online in the TrialDB database (Yale University, New Haven, CT). The response rate was 51% (49 of 97 departments); participating centers represented 60% of all births in the country during the study period. There were 1943 cases of peripartum anesthesia care, of which 1166 cases (60%) were anesthesia for cesarean delivery. Estimates were weighted based on population distribution of cesarean delivery among types of participating centers. Neuraxial anesthesia was used in 55.6% (95% confidence interval [CI], 52.8%-58.5%); the distribution of anesthesia techniques differed among type of participating center. The rate of neuraxial anesthesia in university hospitals was 55.6% (95% CI, 51.5%-59.6%), 32.4% (95% CI, 26.4%-39.0%) in regional hospitals, and 60.7% (95% CI, 55.2%-66.0%) in local hospitals. The reasons for cesarean delivery under general anesthesia were emergency procedure (67%), refusal of neuraxial blockade by parturient (30%), failure of neuraxial anesthesia (6%), and preoperative administration of low-molecular-weight heparin (3%). Postcesarean analgesia was primarily provided by systemic opioid (66%) and nonopioid analgesics (61%), solely or in combination. Epidural postoperative analgesia was used in 14% of cases. Compared with national neuraxial anesthesia rate data published in the 1990s (6.7% in 1993), there has been an upward trend in the use of neuraxial anesthesia for cesarean delivery during the 21st century (40.5% in 2000) in the Czech Republic. The rate of neuraxial anesthesia use for cesarean delivery has increased in the Czech Republic in the last 2 decades. However, the current rate of general anesthesia is high compared with other Western countries.

The polycyclic aromatic hydrocarbon concentrations in soils in the Region of Valasske Mezirici, the Czech Republic

PubMed Central

2009-01-01

The polycyclic aromatic hydrocarbon (PAH) contamination of urban, agricultural and forest soil samples was investigated from samples obtained in the surroundings of Valasske Mezirici. Valasske Mezirici is a town located in the north-east mountainous part of the Czech Republic, where a coal tar refinery is situated. 16 PAHs listed in the US EPA were investigated. Organic oxidizable carbon was also observed in the forest soils. The PAH concentrations ranged from 0.86-10.84 (with one anomalous value of 35.14) and 7.66-79.39 mg/kg dm in the urban/agricultural and forest soils, respectively. While the PAH levels in the urban/agricultural soils are within the range typically found in industrialized areas, the forest soils showed elevated PAH concentrations compared to other forest soils in Western and Northern Europe. The PAH concentrations and their molecular distribution ratios were studied as functions of the sample location and the meteorological history. The soils from localities at higher altitudes above sea level have the highest PAH concentrations, and the PAH concentrations decrease with increasing distance from the town. PMID:20003407

Blood samples from 21 red foxes (Vulpes vulpes) and 8 hunting dogs from the same locality in the Czech Republic were examined for presence of Hepatozoon canis/Hepatozoon sp. The dogs were selected based on their close contact with foxes during fox bolting and because they had not traveled into known endemic areas. Using diagnostic PCR amplifying partial 18S rDNA fragment, Hepatozoon DNA was detected in 20 red foxes (95 %) and 4 dogs (50 %). From 8 positive foxes and 2 positive dogs, we obtained nearly complete 18S rDNA sequences. Phylogenetic analyses of these sequences revealed very low variability. Buffy coat smears from positive dogs were prepared and examined. No Hepatozoon gamonts were found. This study provides the first report of autochthonous infection of H. canis/Hepatozoon in dogs and foxes from the Czech Republic. Our study indirectly demonstrates cross infection between red foxes and dogs and confirms autochthonous infection of Hepatozoon canis in dogs living in a geographic area well outside the range of Rhipicephalus sanguineus sensu lato, which is so far the only known vector of H. canis in Europe.

To track the trends in general health indicators and the prevalence of cardiovascular diseases (CVD), high blood pressure and elevated blood cholesterol in the middle-aged urban population in the Czech Republic in 1998-2010. Cross-sectional study. The following data from the three-phase HELEN (HEalth - Lifestyle - ENvironment) study, a prevalence questionnaire survey, were analysed: data collected from 8214 subjects in phase I, 6107 subjects in phase II, and 4389 subjects in phase III. The study subjects were aged 45-54 years and the study period spanned from 1998 to 2010. The differences in the indicators between phases were evaluated by binary and ordinal logistic regression models at a significance level of 0.01. Over the study period, a significant increase was observed in the proportion of respondents who self-rated their health as very good or good: from 46.6% to 51.0% in males (P = 0.006) and from 45.5% to 49.9% in females (P < 0.001). At the same time, the rates of respondents under long-term medical follow-up rose significantly from 36.3% to 44.3% (P < 0.001) and from 46.4% to 56.2% (P < 0.001), respectively. CVD prevalence did not change although the percentage of males and females with high blood pressure (from 29.3% to 36.6% and from 26.0% to 31.2%, respectively) and elevated total cholesterol (from 29.0% to 36.6% and from 27.3% to 32.4%, respectively) increased significantly. Self-rated health among the middle-aged population in the Czech Republic improved during the 1998-2010 period, but, at the same time, more people needed to be followed up for a disease. The proportions of respondents with hypertension and elevated blood cholesterol increased while the CVD rates did not vary significantly. Copyright © 2015 The Royal Society for Public Health.

The purpose of this paper is to determine how many years a person could be expected to live if a specific cause of death was eliminated, and to compare potential gains in life expectancy (PGLEs) between Slovakia (SVK) and the Czech Republic (CZE). PGLEs were computed from mortality reports (1996-2013) for deaths from the main groups of chronic diseases, namely ischaemic heart disease (IHD), cerebrovascular diseases (CVD), cancer (CA), diabetes mellitus (DM), and chronic respiratory diseases (CRD) for the Slovak and Czech populations in five-year age groups. Country comparative analysis was conducted by constructing rate ratios of PGLEs. In 2013, life expectancy at birth for the Slovak and Czech populations was 76.5 and 78.3 years. Overall trends of standardised mortality rates of chronic diseases roughly paralleled the PGLEs trend. During 1996-2013, SVK reported the highest PGLEs of IHD at an average of 4.54 years, compared to PGLEs of CA reaching a value of 3.61 years in CZE. The PGLEs of IHD showed the largest gap between SVK and CZE, with an average of 1.65 higher values in SVK. With the elimination of CVD as the third most influential disease in both countries, PGLEs decreased from 1.65 to 0.93 years in CZE; a negligible drop from 1.13 to 1.05 was recorded in SVK. The lowest impacts on life expectancy were recorded in DM and CRD. However, since 2005 these trends have deteriorated in CZE. In 2013, IHD had a similar impact on life expectancy in all age groups in SVK and a decreasing impact among 50-54 year olds in CZE. Similarly to SVK, people in CZE aged 45-49 could gain 0.94 years in LE after CVD elimination, which is nearly the same as at birth. The higher the life expectancy after elimination of the cause of death is, the higher the impact of the disease on life expectancy. Health prevention programs should be mainly aimed at CA mortality in CZE, while the highest burden of IHD is seen in SVK. Copyright© by the National Institute of Public Health, Prague 2017.

In longitudinal cohort studies, the relationships between prenatal and postnatal tobacco smoke exposure and infant wheezing illnesses were compared in two geographically defined populations in Avon, UK and Brno and Znojmo in the South Moravian Region of the Czech Republic. Pregnant females living in defined regions and with expected dates of delivery between defined dates were recruited. Females completed self-report questionnaires during pregnancy and when their infant was 6 months old. For this analysis, responses to questions about smoking during pregnancy, environmental tobacco smoke (ETS) exposure and reported wheezing illnesses of infants at 6 months after birth were used. Odds ratios for wheeze in relation to the smoking variables were calculated with adjustment for potential confounding effects. The prevalence of smoking during pregnancy was higher in Avon (17.5%) than the Czech Republic (7.1%). Exposure of infants to ETS during the first 6 months after birth was also reported to be higher in Avon (35.5%) than the Czech Republic (9.7%). The prevalence of reported wheezing by 6 months of age was 21.4% in Avon and 10.3% in Brno and Znojmo. In Avon, there was a significant relationship between infant wheeze and maternal smoking during pregnancy (odds ratio (95% confidence interval) 1.30 (1.09-1.56), p=0.004) but not with environmental exposure after birth (1.11 (0.98-1.25)). In contrast, in Brno and Znojmo in the Czech Republic, there was a significant relationship between infant wheeze and ETS exposure (1.66 (1.17-2.36), p=0.04) but not with maternal smoking during pregnancy (0.99 (0.64-1.55)). This study demonstrated an apparent difference in the associations between prenatal and postnatal tobacco smoke exposure and infant wheezing illnesses in two populations with different smoking prevalence. The relationships were independent of a number of potential confounding variables that have been associated with infant wheezing. Possible explanations of these observations include dose-related effects of prenatal and postnatal tobacco smoke exposure of infants.

A prospective study. Analysis of epidemiological data about acute spinal cord injury (SCI) in the Czech Republic over a period of 10 years (2006-2015). A data collection system was implemented in the rehabilitation centres which provides care to patients with acute SCI in the Czech Republic. The recorded variables are as follows: age at time of SCI; gender; cause of injury; neurological level of injury (NLI); and its severity (ASIA Impairment Scale (AIS)). Data from 2006 to 2015 were analysed and trends were determined. The overall number of acute SCI ranges between 250 and 300 cases annually. Two-third of the affected population are males. The average age at time of SCI is 49.1 years. The average incidence of traumatic SCI is 15.5 cases per year and is gradually decreasing. The leading cause of SCI are falls (44.5%), followed by traffic accidents (28.2%) and sports injuries including diving into water (19.7%). The incidence of non-traumatic SCI is 8.6 cases per year on average and has an upward trend. Inflammatory lesions account for 26.7% of cases, tumours account for 20.9%, and vascular related injuries make up 17.7%. The NLI occurs most often in the cervical segments (45.3%). The most frequently occurring lesions are motor incomplete: AIS D (33.3%). This study shows a stable occurrence of SCI in the Czech Republic, with cervical and motor incomplete cases being the leading ones. Epidemiological data are needed to improve the care of SCI patients and to promote an active life following it.

The Registry of Monoclonal Gammopathies (RMG) was established by the Czech Myeloma Group in 2007. RMG is a registry designed for the collection of clinical data concerning diagnosis, treatment, treatment results and survival of patients with monoclonal gammopathies. Data on patients with monoclonal gammopathy of undetermined significance (MGUS), Waldenström macroglobulinaemia (WM), multiple myeloma (MM) or primary AL ("amyloid light-chain") amyloidosis are collected in the registry. Nineteen Czech centres and four Slovak centres currently contribute to the registry. The registry currently contains records on more than 5,000 patients with MM, almost 3,000 patients with MGUS, 170 patients with WM and 26 patients with primary AL amyloidosis, i.e. more than 8,000 records on patients with monoclonal gammopathies altogether. This paper describes technology employed for the collection, storage and subsequent online visualisation of data. The CLADE-IS platform is introduced as a new system for the collection and storage of data from the registry. The form structure and functions of the new system are described for all diagnoses in general; these functions facilitate data entry to the registry and minimise the error rate in data. Publicly available online visualisations of data on patients with MGUS, WM, MM or primary AL amyloidosis from all Czech or Slovak centres are introduced, together with authenticated visualisations of data on patients with MM from selected centres. The RMG represents a data basis that makes it possible to monitor the disease course in patients with monoclonal gammopathies on the population level.Key words: Registry of Monoclonal Gammopathies - RMG - registries - monoclonal gammopathies - CLADE-IS - data visualisation - database.

The incidence and mortality of renal cell carcinoma (RCC) in the Czech Republic are among the highest in the world. Several targeted agents have been recently approved for the treatment of advanced/metastatic RCC. Presentation of a national clinical database for monitoring and assessment of patients with advanced/metastatic RCC treated with targeted therapy. The RenIS (RENal Information System, http://renis.registry.cz ) registry is a non-interventional post-registration database of epidemiological and clinical data of patients with RCC treated with targeted therapies in the Czech Republic. Twenty cancer centres eligible for targeted therapy administration participate in the project. As of November 2011, six agents were approved and reimbursed from public health insurance, including bevacizumab, everolimus, pazopanib, sorafenib, sunitinib, and temsirolimus. As of 10 October 2011, 1,541 patients with valid records were entered into the database. Comparison with population-based data from the Czech National Cancer Registry revealed that RCC patients treated with targeted therapy are significantly younger (median age at diagnosis 59 vs. 66 years). Most RenIS registry patients were treated with sorafenib and sunitinib, many patients sequentially with both agents. Over 10 % of patients were also treated with everolimus in the second or third line. Progression-free survival times achieved were comparable to phase III clinical trials. The RenIS registry has become an important tool and source of information for the management of cancer care and clinical practice, providing comprehensive data on monitoring and assessment of RCC targeted therapy on a national level.

A germline SNP (rs61764370) is located in a let-7 complementary site (LCS6) in the 3'UTR of KRAS oncogene, and it was found to alter the binding capability of the mature let-7 microRNA to the KRAS mRNA. The aim of the study was to evaluate the frequency of the KRAS-LCS6 variant allele in different cancer types that included patients with colorectal cancer (CRC), breast cancer (BC), non-small cell lung cancer (NSCLC) and brain tumour patient subgroups from the Czech Republic. The occurrence of this genetic variant was correlated with the presence of selected somatic mutations representing predictive biomarkers in the respective tumours. DNA of tumour tissues was isolated from 428 colorectal cancer samples, 311 non-small cell lung cancer samples, 195 breast cancer samples and 151 samples with brain tumour. Analysis of SNP (rs61764370) was performed by the PCR+RFLP method and direct sequencing. KRAS, BRAF and EGFR mutation status was assessed using real-time PCR. The status of the HER2 gene was assessed using the FISH method. The KRAS-LCS6 TG genotype has been detected in 16.4% (32/195) of breast cancer cases (in HER2 positive breast cancer 3.3%, in HER2 negative breast cancer 20.1%), in 12.4% (53/428) of CRC cases (KRAS/BRAF wild type CRC in 10.6%, KRAS mutant CRC in 10.1%, BRAF V600E mutant CRC in 18.5%), in 13.2% (41/311) of NSCLC samples, (EGFR mutant NSCLC patients in 8%, EGFR wild type NSCLC in 12.9%), and 17.9% (27/151) of brain tumour cases. The KRAS-LCS6 TG genotype was not significantly different across the studied tumours. In our study, the GG genotype has not been found among the cancer samples. Based on the findings, it is concluded that the occurrence of the KRAS-LCS6 TG genotype was statistically significantly different in association with status of the HER2 gene in breast cancer. Furthermore, significant association between the mutation status of analysed somatic variants in genes of the EGFR signalling pathway (KRAS, BRAF, EGFR) and the KRAS-LCS6 genotype in colorectal cancer and NSCLC has not been established.

The Czech Republic Global Youth Tobacco Survey (GYTS) is a school-based survey of students in grades 7-9, conducted in 2002. A two-stage cluster sample design was used to produce representative data for all of the Czech Republic. On a large sample of students (N=4,149) from 7-9th grade it reveals that smoking among children has been continually growing. According to the results of this study, over 34% of the respondents smoke. Results of the study help us to understand social and attitudinal factors that affect adolescent smoking habits. Social factors include particularly the convenient availability of cigarettes and the lack of the legal regulation of the retail of cigarettes: over one half of all smokers under 15 years of age regularly purchase cigarettes in regular retail outlets; 72% of them reported never having been restricted in their purchases because of their age. Advertising and media coverage appears to be another important factor that affects smoking in this age group. Over 80% of children under 15 years of age reported that they have been exposed to the tobacco advertising. The study also allows an interesting analysis of the exposure to the environmental tobacco smoke. Compared to non-smokers, this exposure has been significantly higher in the case of smokers--both in their homes and at other locations (58% vs. 25%, and 90% vs. 57% respectively). The analysis of the data also revealed a strong misconception about the health risks related to passive smoking among smokers. The study provides three key findings for health promotion: (1) it is necessary to exert a continuous pressure on the political representation to strictly enforce the regulations of tobacco distribution and availability to minors; (2) school health education as well as community oriented prevention programs need to explicitly communicate non-smoking as a standard; and (3) it is important to increase the attractiveness and availability of smoking cessation programs.

Neospora caninum and Toxoplasma gondii are worldwide spread parasites, causing serious illnesses in sensitive animals; toxoplasmosis is also important zoonosis. Although neosporosis is not considered as a zoonosis, it leads to aborted births in cattle, as well as paresis and paralysis in dogs. The aim of this study was to discover the prevalence of N. caninum and T. gondii antibodies in red foxes (Vulpes vulpes) in the Czech Republic. Sera of 80 foxes from 8 regions of the Czech Republic were tested for antibodies to N. caninum and T. gondii by competitive enzyme linked immunosorbent assay (cELISA) and indirect ELISA. All samples were simultaneously tested by indirect fluorescent antibody test (IFAT) to detect both N. caninum and T. gondii antibodies. Antibodies to N. caninum were found by IFAT in 3 (3.8%) red foxes with titre 50 and in 2 (2.5%) red foxes with inhibition 42.7% and 30.2 %. Antibodies to T. gondii were found in all tested animals in both IFAT (titres 50-6400) and in ELISA (S/P ranging from 34%-133%). This is the first prevalence study of N. caninum and T. gondii antibodies in red foxes in the Czech Republic. The results obtained show that red foxes are exposed at different levels to both protozoan infections, and thus could play an important role in the transmission cycle of N. caninum and T. gondii in sylvatic cycle.

Life-history strategies associated with local population variability confer regional stability.

PubMed

Pribil, Stanislav; Houlahan, Jeff E

2003-07-07

A widely held ecological tenet is that, at the local scale, populations of K-selected species (i.e. low fecundity, long lifespan and large body size) will be less variable than populations of r-selected species (i.e. high fecundity, short lifespan and small body size). We examined the relationship between long-term population trends and life-history attributes for 185 bird species in the Czech Republic and found that, at regional spatial scales and over moderate temporal scales (100-120 years), K-selected bird species were more likely to show both large increases and decreases in population size than r-selected species. We conclude that life-history attributes commonly associated with variable populations at the local scale, confer stability at the regional scale.

The aim of this study was to psychometrically evaluate the shortened version of the Spiritual Well-Being Scale (SWBS) in Czech adolescents. A nationally representative sample of 4217 adolescents participated in the 2014 Health Behaviour in School-aged Children survey. The internal consistency of the SWBS was assessed using Cronbach's alpha (α) and Mean Inter-Item Correlation (MIIC) values. The factor structure was evaluated using principal component analyses. After adjustment, our new seven-item version of the scale supports a two-factorial model of the SWBS with satisfactory internal consistency (α = 0.814, MIIC = 0.379). This version of the SWBS is suitable for measuring spiritual well-being in a secularising environment.

β-Thalassemia (β-thal) is considered rare in Central Europe. As in other malaria-free regions, the presence of β-thal in Central Europe reflects historical and recent immigration, and demographic changes that have influenced the genetic variability of the current populations living in this area. This study assesses the frequency and spectrum of mutations on the β-globin gene in Czech and Slovak subjects with clinical symptoms of thalassemia. The results of the initial part of this research were published more than two decades ago; the aim of this study was to update these original reports. During the period from 2002 to 2015, 400 cases from Czech and Slovak hematological centers were analyzed. Twenty-nine β-thal mutations, identified in 356 heterozygotes from 218 unrelated families, involve five unique mutations including a recently described insertion of a transposable L1 element into the β-globin gene. One mutation described here is reported for the first time. Most of the mutations were of Mediterranean origin and accounted for 82.0% of cases. All but one case studied were heterozygous carriers, manifesting β-thal minor, with rare exceptions represented by the rare (β(0)) codons 46/47 (+G) (HBB: c.142_142dupG) mutation associated with an α-globin gene quadruplication and by dominantly inherited β-thal with a more severe phenotype. One double heterozygous β-thal patient was a recent immigrant from Moldavia. The list of δβ-thal alleles (26 carriers, 16 families) contains Hb Lepore and two types of δβ(0)-thal deletions. In the past, genetic drift and migration as well as recent immigrations were responsible for the introduction of Mediterranean alleles, while several mutations described in single families were of local origin.

This article describes the evolution of our understanding of familial hypercholesterolemia (FH) in the Central, Eastern, and Southern Europe (CESE) region, and the dissemination of this understanding to other countries. Using the ScreenPro FH project as an example, we would like to illustrate the progression from national objectives, to regional networking and, finally, to international collaboration via the Familial Hypercholesterolemia Studies Collaboration (FHSC) project under the leadership of the European Atherosclerosis Society (EAS). It is essential to improve our ability to diagnose FH. In this regard, the EAS and its FHSC project must be commended for their educational and organizational activities which, above all, are dedicated to the creation of a global FH patient registry. In the CESE region, FH diagnostics and treatment situation are markedly different than in Western Europe or North America. Since the Czech MedPed project (Make Early Diagnoses to Prevent Early Deaths in Medical Pedigrees) has been so successful (with results not only comparable to, but, for some parameters, even surpassing the results of many Western countries) we decided to apply the Czech experience to the CESE region. Thus, the ScreenPro FH project was created. The aim of ScreenPro FH is to create a specialist network in the CESE region. The primary objective of the ScreenPro FH project was to dramatically reduce the number of premature deaths due to clinical complications of atherosclerosis in FH patients. At present, ScreenPro FH comprises 18 member countries with a total population of 500,000,000; which, in terms of the FH population, represents 1-2 million patients.

Curing over-use by prescribing fees: an evaluation of the effect of user fees' implementation on healthcare use in the Czech Republic.

In 2008, the Czech Republic instituted a new policy that requires most patients to pay a small fee for some inpatient and outpatient healthcare services. Using the Survey of Health Aging and Retirement in Europe, this article examines the changes in healthcare utilization of Czechs 50 years and older following the new fee requirement by constructing difference-in-differences regression models focusing on four outcome measures: any visits to primary care physician, any hospitalization, number of visits to the primary care physician and number of nights hospitalized. For this population, I find that the likelihood of having any primary care visit decreased after the policy was instituted. The likelihood of reporting any hospitalization was not significantly changed. The predicted number of primary care visits per person declined, but the predicted number of nights spent in a hospital did not. I find only mixed evidence of greater effect of the user fees on some subpopulations compared with others. Those 65 or older reduced their use more than those between 50 and 64, and so did those who consider their health to be good, and the less educated.

The sexual attitudes of 1719 (862 male, 857 female) respondents over 15 years of age were investigated by an anonymous survey who made up a representative sample of the population of the Czech Republic. The questionnaire contained a total of 35 questions. The findings showed objections, in principle, against premarital sexual intercourse and abortion (3.3% of men, 3.6% of women), while 57.5% of women and 59.7% of men stated that every woman has the right to decide whether to bear children. 3.0% of men and 4.4% of women were altogether against premarital sexual intercourse, while 50.3% of men and 69.4% of women deemed that it is allowed within the framework of a lasting relationship. 4.0% of men and 8.6% of women thought that pornography should be banned. 36% (22.7% of men, 46.4% of women) were against group sexual activity, while 53.7% of men and 47.7% of women deemed it acceptable but would refuse to take part in it. 24% (18.3% of men, 30.9% of women) were against extramarital intercourse, while 44.0% of men and 25.7% of women thought it was natural and normal. 28% (14.5% of men, 39.9% of women) were against casual sex, while 40.3% of men and 41.8% of women did not condemn it, but would not engage in it either. 7% (5.0% of men, 9.6% of women) were against masturbation and considered it harmful, while 65.5% of men and 58.4% of women thought it was a natural manifestation of human sexuality. 6% (6.1% of men, 5.7% of women) were against homosexual intercourse, while 33.4% of men and 41.0% of women thought it was a disease, which those afflicted could not help. 5% of men and 4.4% of women rejected contraceptive use.

Impact of quadrivalent human papillomavirus vaccine in women at increased risk of genital warts burden: Population-based cross-sectional survey of Czech women aged 16 to 40 years.

To assess the impact of a quadrivalent human papillomavirus vaccine (4HPV) in women at increased risk of genital warts (GWs) acquisition. The study was conducted using a population-based cross-sectional survey of 19,199 women aged 16 to 40 years randomly chosen from the general population in the Czech Republic between January 2013 and March 2014. A total of 1086 women reported having received the 4HPV vaccine. The vaccine's effectiveness was estimated not only in the general population of women but also in those at increased risk due to having a sexual partner with GWs or prior GWs history. The acquisition of GWs was dramatically reduced by 90.6% (80.1-95.6%) in immunised women at least one year after the completion of the 4HPV vaccination in comparison with unimmunised women. Recurrent GWs prevalences of 1.1% (95% CI, 0.0-5.9) and 10.9% (95% CI, 9.1-12.9) in immunised and unimmunised women with prior GWs history, respectively, resulted in a vaccine effectiveness of 89.0% (38.6-98.0%). The notably strong protective effect of 4HPV immunisation in women who had a sexual partner with GWs was demonstrated by a very low age-adjusted odds ratio of 0.02 (95% CI 0.01-0.10) in contrast to unimmunised women. To lower the chance of genital warts acquisition in the general population and in populations at increased risk, only current 4HPV or incoming 9HPV vaccination should be recommended to provide effective protection.

This study examined a) trends in overweight/obesity, moderate-to-vigorous physical activity (MVPA), and screen time (ST) among Czech adolescents over a 12-year study period (2002-2014) in relation to family affluence (FA) and b) correlates of adolescent overweight/obesity from different FA categories. A nationally representative sample of 18,250 adolescents (51.4% girls) aged 10.5-16.5 years was drawn from the Czech Health Behaviour in School-aged Children questionnaire-based surveys in 2002, 2006, 2010, and 2014. Using the FA scale, the socioeconomic status (SES) of the respondents' families was assessed. SES-stratified trends in the prevalence of overweight/obesity meeting the MVPA (≥60 min/day), and ST (≤2 h/day) recommendations were assessed using logistic regression. A trend-related significant increase (p < 0.05) in the prevalence of overweight/obesity was observed in low-/medium-FA boys and medium-/high-FA girls. Unlike in high-FA adolescents, a significant decrease was revealed in the rates of meeting the MVPA recommendation in low-FA boys (28.9% 2002  → 23.3% 2014 , OR = 0.75, 95% CI = 0.59-0.95, p < 0.05) and girls (22.3% 2002  → 17.3% 2014 , OR = 0.73, 95% CI = 0.57-0.92, p < 0.01). A significant (p < 0.001) trend-related increase in excessive ST was evident in adolescents regardless of gender and FA category. Generally, girls and older adolescents had lower odds of overweight/obesity than boys and 11-year-old adolescents. While in the high-FA category of adolescents, achieving 60 min of MVPA daily and the absence of excessive ST on weekdays significantly (p < 0.01) reduced their odds of being overweight/obese, in low-FA adolescents this was not the case. High rates of overweight/obesity and a poor level of daily MVPA among low-FA children provide disturbing evidence highlighting the necessity of public health efforts to implement obesity reduction interventions for this disadvantaged population.

Thirty-Year-Old Paradigm about Unpalatable Perch Egg Strands Disclaimed by the Freshwater Top-Predator, the European Catfish (Silurus glanis)

So far, perch egg strands have been considered unpalatable biological material. However, we repeatedly found egg strands of European perch (Perca fluviatilis) in the diet of European catfish (Silurus glanis) caught by longlines in Milada and Most Lakes, Czech Republic. The finding proves that perch egg strands compose a standard food source for this large freshwater predatory fish. It extends the present knowledge on catfish foraging plasticity, showing it as an even more opportunistic feeder. Utilization of perch egg strands broadens the catfish diet niche width and represents an advantage against other fish predators. Comparison of datasets from extensive gillnet and SCUBA diver sampling campaigns gave the evidence that at least in localities where food sources are limited, multilevel predation by catfish may have an important impact on the perch population.

The tsunami disaster affected several countries in Southeast Asia in December 2004 and killed or affected many tourists, most of them from Europe. Eight Czech citizens died, and about 500 Czechs were seriously mentally traumatized. The psychosocial needs of tourists included: (1) protection; (2) treatment; (3) safety; (4) relief; (5) psychological first aid; (6) connecting with family members; (7) transportation home; (8) information about possible mental reactions to trauma; (9) information about the normality of their reaction; (10) procedural and environmental orientation; (11) reinforcement of personal competencies; and (12) psycho-trauma therapy. The Ministry of Foreign Affairs of the Czech Republic was in charge of general emergency management. General coordination of psychosocial support was coordinated under the Ministry of Interior of the Czech Republic, which is connected to the Central Crisis Staff of the Czech Government. The major cooperative partners were: the Ministry of Foreign Affairs, the Ministry of Defence, the Ministry of Health, Czech Airlines, psychosocial intervention teams of the Czech Republic, and the Czech Association of Clinical Psychologists. The main goals of relief workers were: (1) to bring back home the maximum number of Czech citizens; (2) to provide relevant information to the maximum number of affected Czech citizens; (3) to provide relevant information to rescue workers and professionals; and (4) to prepare working psychosocial support regional network. Major activities of the Ministry of Interior (psychology section) included: (1) establishing a psychological helpline; (2) running a team of psychological assistance (assistance in the Czech airports, psychological monitoring of tourists, crisis intervention, psychological first aid, assistance in the collection of DNA material from relatives); (3) drafting and distributing specific information materials (brochures, leaflets, address lists, printed and electronic instructions); (4) communicating via the media and advertising, and (5) providing analysis and research studies. Central coordination of psychosocial support has been found as successful in the first phase after the disaster. The plans must be built for preferable cooperation in the psychosocial field in the Czech Republic. Better collaborates with journalists must exist in order to reduce secondary psycho-trauma. There is a need for intensive international cooperation in the psychosocial field and to build the network at the global level.

Carbonaceous aerosol (TC) is a complex mixture of many organics (OC fraction) and elemental carbon (EC). EC is a product of anthropogenic activities, especially incomplete combustion of fossil fuels by transport, heating, power plants, wood and biomass burning and agriculture activities. EC could have larger health impact than other PM constituents (Cassee et al., 2013). Carbonaceous aerosols also play an important role in climate change (Boucher et al., 2013). Kosetice Observatory, operated by the Czech Hydrometeorological Institute has been carrying out long-term air quality monitoring at the background scale the Czech Republic since 1988. Regular EC-OC measurement has been implementing within EU-projects EUSAAR and ACTRIS since 2009. Sampling frequency is every 6th day in fraction PM2,5 on 2 quartz-fibre filters. Since October 2011 the sampling on filters has been implementing behind the denuder catching the organic vapor. Amount of OC on back quartz fiber filter represents positive artifact by measurement without denuder and negative artifact by measurements with denuder. The analytical method is thermal-optical analysis. The samples are analyzed in CHMI Central Laboratories in Prague-Libuš using EC-OC Sunset Lab Dual Analyzer. Charring correction is made by laser transmission monitoring. Slightly decreasing tendency of EC-OC was found in the period under review (2009-2014). The mean annual concentration of total carbon (TC) in PM2,5 was 3,73 µg.m-3. The figure for elemental carbon (0,5 µg.m-3) represents the mean annual ratio of 13% on TC. EC-OC concentrations follow an annual course that reflects their emission levels, i.e. with maximums in winter and minimums in summer. The seasonal variation of EC/TC ratio ranges between 9,6 (summer) - 14,2% (winter). Mean TC ratio on PM2,5 total mass in the period under review was 29%, the highest ratios reached 50%. EC participated on PM2,5 total mass by 3,5% in average. 3D trajectories were used for sector analysis of measured EC-OC data (NILU, 2016). The highest concentrations are recorded in situations when air masses reach the territory of the Czech Republic from the north-eastern directions or the local air masses prevailing. The differences between sectors are much larger in the cold period of the year.

The aim of this study was to assess the contamination level of aquatic ecosystems of the Oslava and the Jihlava Rivers, and of the Nove Mlyny Water Reservoir, situated in the South Moravian Region (Czech Republic), by residues of selected veterinary pharmaceuticals. We isolated and determined 10 sulfonamide antibiotics in samples of surface water and bottom sediments using optimized analytical methods. A representative number of sampling sites in the entire basin of selected waters were chosen. Samples were collected particularly near the larger cities in order to assess their possible impact to the aquatic ecosystems. Extraction, pre-concentration and purification of samples were performed using optimized methods of solid phase extraction and pressurized solvent extraction. Final identification and quantification were carried out by high-performance liquid chromatography coupled with diode array detector. The concentration of sulfonamides in water samples were all under the limit of detection. Regarding sediment samples, sulfadimidine was found at most sampling sites; its highest values were recorded in the Jihlava River (up to 979.8 µg.kg(-1) dry matter). Other frequently detected sulfonamides were sulfamethoxazole and sulfamerazine. Most other sulfonamides were under the limit of detection or limit of quantification. Monitoring of antibiotic residues in the environment, especially in the aquatic ecosystem, is a current topic due to the growing worldwide use in both human and veterinary medicine. According to obtained results, we document the pollution of selected rivers and water reservoir by particular sulfonamides which basically reflects their application in veterinary medicine.

Transboundary Air-Pollution Transport in the Czech-Polish Border Region between the Cities of Ostrava and Katowice.

The Czech Hydrometeorological Institute (CHMI) estimated the transboundary transport of air pollution between the Czech Republic and Poland by assessing relationships between weather conditions and air pollution in the area as part of the "Air Quality Information System in the Polish-Czech border of the Silesian and Moravian-Silesian region" project (http://www.air-silesia.eu). Estimation of cross-border transport of pollutants is important for Czech-Polish negotiations and targeted measures for improving air quality. Direct measurement of PM 10 and sulphur dioxide (SO 2 ) concentrations and the direction and wind speed from measuring stations in the vicinity of the Czech-Polish state border in 2006-2012. Taking into account all the inaccuracies, simplifications and uncertainties, by which all of the measurements are affected, it is possible to state that the PM 10 transboundary transport was greater from the direction of Poland to the Czech Republic, rather than the other way around. Nevertheless, the highest share of the overall PM 10 concentration load was recorded on days with a vaguely estimated airflow direction. This usually included days with changing wind direction or days with a distinct wind change throughout the given day. A changeable wind is most common during low wind speeds. It can be assumed that during such days with an ambiguous daily airflow, the polluted air saturated with sources on both sides of the border moves from one country to the other. Therefore, we could roughly ascribe an equal level of these concentrations to both the Czech and Polish side. PM 10 transboundary transport was higher from Poland to the Czech Republic than from the opposite direction, despite the predominant air flow from the Czech Republic to Poland.

On the basis of previous findings on random individuals, we hypothesized a preferential association of CF causing mutations with the M allele of the M470V polymorphic site of the CFTR gene. We have determined the M/V-CF mutation haplotype in a series of 201 North East Italian and 73 Czech CF patients who were not F508del homozygotes, as F508del was already known to be fully associated with the M allele. Out of 358 not F508del CF genes, 84 carried the V allele and 274 the less common M allele. In the N-E Italian population, MM subjects have a risk of carrying a CF causing mutation 6.9x greater than VV subjects when F508del is excluded and 15.4x when F508del is included. In the Czech population a similar, although less pronounced, association is observed. Besides the possible biological significance of this association, the possibility of exploiting it for a pilot screening program has been explored in a local North East Italian population for which CF patients were characterized for their CF mutation. General M470V genotyping followed by common CF mutation screening limited to couples in which each partner carries at least one M allele would need testing only 39% of the couples, which contribute 89% of the total risk, with a cost benefit.

The aim of the study was the monitoring of six biogenic amines (histamine, tyramine, phenylethylamine, tryptamine, putrescine, and cadaverine) and two polyamines (spermidine and spermine) in 112 samples of dairy products purchased in the Czech Republic, namely in 55 cheeses made in small-scale farms and in 57 fermented dairy products. The products were tested at the end of their shelf-life period. Neither tryptamine nor phenylethylamine was detected in the monitored samples; histamine was found only in four cheese samples containing up to 25mg/kg. The contents of spermine and spermidine were low and did not exceed the values of 35 mg/kg. Significant amounts of tyramine, putrescine, and cadaverine occurred especially in cheeses produced from ewe's milk or in long-term ripened cheeses. In about 10% of the tested cheeses, the total concentration of all the monitored biogenic amines and polyamines exceeded the level of 200mg/kg, which can be considered toxicologically significant. In fermented dairy products, the tested biogenic amines occurred in relatively low amounts (generally up to 30 mg/kg) that are regarded safe for the consumer's health. Copyright © 2013 Elsevier Ltd.

Human polyomaviruses such as JC polyomavirus and BK polyomavirus have long been well known pathogens of immunocompromised patients. Several new members of this viral family have been described during the last decade. Human polyomavirus 9 seems to be a novel pathogen of transplanted patients according to some studies. The aim of our study was to determine the presence of human polyomavirus 9 in patients after kidney or stem cell transplantation (SCT) at the University Hospital in Hradec Kralove, Czech Republic. Overall 100 patients, 65 after kidney transplantation and 35 after SCT, were included into the study. At least three follow-up samples from each patient were examined for human polyomavirus 9 DNA presentation with the two previously described in-house PCR protocols. Despite the frequent reactivation of human CMV (14.3% in kidney transplantation and 63.3% after SCT) or BK polyomavirus in our patient group, there was no positivity for human polyomavirus 9 either in blood samples or urine samples. One of the possible reasons for this discrepancy versus previous published studies could be a relatively low proportion of patients treated by induction therapy before kidney transplantation in our study cohort. © 2017 Wiley Periodicals, Inc.

The Aurora Project, aimed at promotion of cervical cancer prevention, was realised with the support of the European Commission. The project included 14 partners from 11 EU countries. The objective of this contribution was to analyse the level of knowledge on cervical cancer among respondents in the project partner countries and to compare the situations in Slovakia and the Czech Republic. Data were obtained within one of the project outputs: Work Package 2 (WP2) Dissemination of Aurora Project Objectives and Results. The questionnaire used included 10 questions (available at the project website www.aurora-project.eu) and has been translated into 11 languages of the project partners. In total, 2111 questionnaires were analysed (91.7% response rate), among them 246 were from Slovakia and 305 from the Czech Republic. Descriptive statistical methods and the χ2 test were used to analyse data. The level of knowledge in Slovak and Czech respondents was comparable in answers to seven questions. Statistically significant differences were observed in answers to questions about anatomy and cervical cancer therapy. Answers to the question, 'What are the symptoms of cervical cancer in the early stages?', should be considered as crucial to understand attitudes of the lay population towards prevention. There were 7% of women in the Czech Republic and 16% in Slovakia with the opinion that there is some clinical manifestation of such a condition. This means that women with such an opinion have no reason to visit a gynaecologist while no signs of a disease are present. The period during which they do not attend a preventive check-up is sufficient for the development of precancerous lesions or even cancer. Recommendations of doctors play a key role in primary and secondary prevention of the disease. An important part of interventions includes information campaigns and educational programmes. The internet is another important source of information, especially for younger generations. Together, these can contribute to increased participation in preventive check-ups by education of the general public. Thus, the disease can be detected early and the development of cervical cancer prevented.

This article deals with the issue of social exclusion of immigrants in the Czech Republic. A review of expert sources indicates that immigrants are most often excluded from the labour market, housing market, and in communication with institutions. These areas became the target of our research. We observed how they were affect by knowledge of the Czech language, length of residence and type of work performed. The study was conducted using quantitative research strategies, interviews, and a questionnaire, the clarity of which was ensured by a double translation. The research group consisted of immigrants, namely Vietnamese, Slovak, Russian, Ukrainian, and Polish nationalities, living in selected regions of the Czech Republic. Results showed that there were statistically significant differences among the immigrant groups. The Vietnamese were least satisfied with housing conditions; they often reported living in overcrowded apartments and dormitories, and saw little chance of changing their situation because of discrimination by landlords. With regard to Czech language skills, the greater difference between Czech and Vietnamese and the relative similarity between Czech and the other studied immigrant languages also played a role. As a result, this indicator also showed the greatest dissatisfaction among the Vietnamese. For employees, poor knowledge of Czech corresponds to lower socioeconomic status.

Estimation of end of life mobile phones generation: The case study of the Czech Republic

Highlights: Black-Right-Pointing-Pointer In this paper, we define lifespan of mobile phones and estimate their average total lifespan. Black-Right-Pointing-Pointer The estimation of lifespan distribution is based on large sample of EoL mobile phones. Black-Right-Pointing-Pointer Total lifespan of Czech mobile phones is surprisingly long, exactly 7.99 years. Black-Right-Pointing-Pointer In the years 2010-20, about 26.3 million pieces of EoL mobile phones will be generated in the Czech Republic. - Abstract: The volume of waste electrical and electronic equipment (WEEE) has been rapidly growing in recent years. In the European Union (EU), legislation promoting the collection and recycling of WEEE has been in forcemore » since the year 2003. Yet, both current and recently suggested collection targets for WEEE are completely ineffective when it comes to collection and recycling of small WEEE (s-WEEE), with mobile phones as a typical example. Mobile phones are the most sold EEE and at the same time one of appliances with the lowest collection rate. To improve this situation, it is necessary to assess the amount of generated end of life (EoL) mobile phones as precisely as possible. This paper presents a method of assessment of EoL mobile phones generation based on delay model. Within the scope of this paper, the method has been applied on the Czech Republic data. However, this method can be applied also to other EoL appliances in or outside the Czech Republic. Our results show that the average total lifespan of Czech mobile phones is surprisingly long, exactly 7.99 years. We impute long lifespan particularly to a storage time of EoL mobile phones at households, estimated to be 4.35 years. In the years 1990-2000, only 45 thousands of EoL mobile phones were generated in the Czech Republic, while in the years 2000-2010 the number grew to 6.5 million pieces and it is estimated that in the years 2010-2020 about 26.3 million pieces will be generated. Current European legislation sets targets on collection and recycling of WEEE in general, but no specific collection target for EoL mobile phone exists. In the year 2010 only about 3-6% of Czech EoL mobile phones were collected for recovery and recycling. If we make similar estimation using an estimated average EU value, then within the next 10 years about 1.3 billion of EoL mobile phones would be available for recycling in the EU. This amount contains about 31 tonnes of gold and 325 tonnes of silver. Since Europe is dependent on import of many raw materials, efficient recycling of EoL products could help reduce this dependence. To set a working system of collection, it will be necessary to set new and realistic collection targets.« less

Despite the undisputed public health benefits of routine vaccination, adverse events following immunisation (AEFI) remain a concern. As most adverse events are mild, they may be under-reported; this may underlie the wide range of AEFI rates reported in the literature. We investigated the rates of AEFI related to routine vaccination of children 0-10 years old in the Czech Republic. The study reviewed patients' records in a sample of 49 paediatric GP practices covering all 12 administrative regions of the Czech Republic between 2011 and 2013. Adverse events following routine immunisation of children aged 0-10 years were identified and recorded. The overall rate of AEFI was 209/100,000 doses; this was 6 times higher than the rate reported to the Czech State Institute for Drug Control (34/100,000 doses). Over two fifths (44%) of all AEFI occurred after the booster dose of the combined diphteria, tetanus and pertussis vaccine in 5-year old children. The vast majority of AEFI were non-serious local events (e.g. redness) and fever. Most AEFI occurred the second day after the immunisation, lasted 4 days on average, and were treated by cold therapy, antipyretics and analgesics. The rate of AEFI identified in this study was considerably higher than the officially reported rate. Although the vast majority of AEFI were non-serious, health care providers and the public should be educated and encouraged to report AEFI to address the issue of underreporting, to increase the safety profile of vaccines, and to improve public confidence in immunisation programmes.

This study examines trends in overweight and obesity, physical activity (PA) and screen time (ST) among Czech adolescents over a recent 12-year study period. Nationally representative samples consisted of 19,940 adolescents (9760 boys and 10,180 girls) aged 10.5–16.5 years from the Czech Health Behaviour in School-aged Children (HBSC) questionnaire-based surveys conducted in 2002, 2006, 2010 and 2014. Trends in the prevalence of overweight/obesity, meeting the recommendations for moderate-to-vigorous PA (MVPA) (≥60 min per day of MVPA) and excessive ST (>2 h per day) were estimated using logistic regression. Significant increases (p < 0.001) in the prevalence of overweight/obesity between the years 2002 and 2014 were evident for both adolescent boys (18.3%2002–24.8%2014) and girls (8.3%2002–11.9%2014). Compared to 2002, in 2014 significant decreases (p < 0.001) in meeting MVPA recommendations were observed among boys (32.2%2002–25.6%2014) and girls (23.2%2002–19.2%2014). Moreover, in boys we observed significant increases (p < 0.001) in excessive ST on weekdays (75.1%2002–88.8%2014), as well as on weekends (78.3%2002–91.9%2014) between the years 2002 and 2014. Increases in overweight/obesity with concomitant decreases in PA provide evidence in support of the current and upcoming efforts of government and commercial organizations in implementing interventions aimed at reducing excessive body weight among Czech adolescents.

Sexual medicine would benefit from large representative surveys examining the prevalence of genital female sexual arousal disorder (FSAD) symptoms (with and without the increasingly controversial distress criterion), as well as novel FSAD correlates and potential "protective" factors. To examine the extent to which genital FSAD symptoms, with and without a distress criterion, are associated with both historical and current aspects of sexual behavior. In a representative sample of the Czech population (aged 15-88), 1,000 women were asked whether they currently have impaired lubrication and vaginal swelling (and if so, if this produces marked distress or interpersonal difficulty). They provided details of vaginal orgasm (induced by penile-vaginal intercourse [PVI] without clitoral masturbation) consistency, feelings during their first PVI, estimates of their typical foreplay and PVI durations, their degree of mental focus on vaginal sensations during PVI, among other factors. The current prevalence of FSAD with and without a distress criterion and their associations with current and antecedent sexual behaviors and responses. The current prevalence of FSAD was 10.3% without, plus 7.5% with a distress criterion (which tended to be associated with more impairments than without distress). History of vaginal orgasm (odds ratio = 2.78), never masturbating (odds ratio = 2.4), not having felt pain and discomfort on first PVI (odds ratio = 2.27), and not having frequent anal intercourse are protective against FSAD with distress, but not without distress. Age (especially over 50) and inadequate focusing of mental attention on vaginal sensations during PVI are associated with increased FSAD risk both with and without distress. FSAD with and without distress appear to be different entities to some extent, with the distressed group showing more long-term signs of psychosexual impairment. We suggest that FSAD with and without distress be considered two different disorders.

Secular trends: a ten-year comparison of the amount and type of physical activity and inactivity of random samples of adolescents in the Czech Republic

Background An optimal level of physical activity (PA) in adolescence influences the level of PA in adulthood. Although PA declines with age have been demonstrated repeatedly, few studies have been carried out on secular trends. The present study assessed levels, types and secular trends of PA and sedentary behaviour of a sample of adolescents in the Czech Republic. Methods The study comprised two cross-sectional cohorts of adolescents ten years apart. The analysis compared data collected through a week-long monitoring of adolescents' PA in 1998-2000 and 2008-2010. Adolescents wore either Yamax SW-701 or Omron HJ-105 pedometer continuously for 7 days (at least 10 hours per day) excluding sleeping, hygiene and bathing. They also recorded their number of steps per day, the type and duration of PA and sedentary behaviour (in minutes) on record sheets. In total, 902 adolescents (410 boys; 492 girls) aged 14-18 were eligible for analysis. Results Overweight and obesity in Czech adolescents participating in this study increased from 5.5% (older cohort, 1998-2000) to 10.4% (younger cohort, 2008-2010). There were no inter-cohort significant changes in the total amount of sedentary behaviour in boys. However in girls, on weekdays, there was a significant increase in the total duration of sedentary behaviour of the younger cohort (2008-2010) compared with the older one (1998-2000). Studying and screen time (television and computer) were among the main sedentary behaviours in Czech adolescents. The types of sedentary behaviour also changed: watching TV (1998-2000) was replaced by time spent on computers (2008-2010). The Czech health-related criterion (achieving 11,000 steps per day) decreased only in boys from 68% (1998-2000) to 55% (2008-2010). Across both genders, 55%-75% of Czech adolescents met the health-related criterion of recommended steps per day, however less participants in the younger cohort (2008-2010) met this criterion than in the older cohort (1998-2000) ten years ago. Adolescents' PA levels for the monitored periods of 1998-2000 and 2008-2010 suggest a secular decrease in the weekly number of steps achieved by adolescent boys and girls. Conclusion In the younger cohort (2008-2010), every tenth adolescent was either overweight or obese; roughly twice the rate when compared to the older cohort (1998-2000). Sedentary behaviour seems relatively stable across the two cohorts as the increased time that the younger cohort (2008-2010) spent on computers is compensated with an equally decreased time spent watching TV or studying. Across both cohorts about half to three quarters of the adolescents met the health-related criterion for achieved number of steps. The findings show a secular decrease in PA amongst adolescents. The significant interaction effects (cohort × age; and cohort × gender) that this study found suggested that secular trends in PA differ by age and gender. PMID:21943194

To assess the relationship between several socio-economic indicators and frequency of consumption of seven predefined healthy foods (consumption of fruit, vegetables, wholegrain bread, vegetable-fat spread, vegetable cooking fat, low-fat milk and low-fat cheese) in populations from Eastern, Central and Western Europe. Analysis of baseline data collected in two cross-sectional cohort studies between 2000 and 2005: the Health, Alcohol and Psychosocial factors In Eastern Europe (HAPIEE) study and the Finnish Helsinki Health Study (HHS). Urban populations in the Czech Republic, Russia, Poland and Finland. In the HAPIEE study, random samples of men and women aged 45-69 years were drawn from population registers and electoral lists of selected cities. In the HHS, men and women aged 40-60 years employed by the City of Helsinki were recruited. Data on 21,326 working subjects from both cohorts were analysed. Healthy food habits were, in general, positively associated with higher education, occupational position and fewer economic difficulties, but there were differences in the strength of the gradient by food and country. Fruit consumption showed the most consistent gradients, especially in relation to socio-economic status among men (country-specific relative index of inequality (RII)=2.02-5.17) and women (RII=2.09-3.57). The associations between socio-economic indicators and healthy food habits showed heterogeneity between countries. Future studies of dietary behaviours should consider multiple measures of socio-economic position.

Promiscuity is related to masculine and feminine body traits in both men and women: evidence from Brazilian and Czech samples.

One of the possible explanations for human within-sex variation in promiscuity stems from conditional strategies dependent on the level of body sex-dimorphism. There is some evidence that masculine men and feminine women are more promiscuous than their sex-atypical counterparts, although mixed results persist. Moreover, another line of evidence shows that more promiscuous women are rather sex-atypical. We tested whether diverse sex-dimorphic body measures (2D:4D, WHR/WSR, handgrip strength, and height and weight) influence sociosexual desires, attitudes, promiscuous behavior, and age of first intercourse in a sex-typical or sex-atypical direction. Participants were 185 young adults, 51 men and 54 women from Brazil, and 40 men and 40 women from the Czech Republic. In men stronger handgrip and more feminine 2D:4D predicted higher sociosexual behaviors, desires, and lower age of the first sexual intercourse. While in women, sociosexual desires were predicted by lower handgrip strength and more feminine 2D:4D. It thus seems that it is rather a mixture of masculine and feminine traits in men, and feminine traits in women that increase their sociosexuality. Masculine traits (height) predicting female promiscuous behavior were specific for only one population. In conclusion, a mosaic combination of sex-typical but also sex-atypical independent body traits can lead to higher promiscuity, particularly in men. Limitations, implications, and future directions for research are considered. This article is part of a Special Issue entitled: Neotropical Behaviour. Copyright © 2014 Elsevier B.V.

Analysis of invasive meningococcal disease (IMD) surveillance data including molecular epidemio-logy data. Vaccination strategy recommendations based on the current epidemiological situation of IMD in the Czech Republic and availability of meningococcal vaccines. IMD surveillance data are compiled by the National Reference Laboratory for Meningococcal Disease (NRL) from routinely reported data and NRL data after clearing out duplicate data. Neisseria meningitidis (N.m.) isolates referred to the NRL are confirmed and characterized in detail according to internationally validated methods. The current epidemiological situation of IMD is relatively favourable - the incidence rates have been below 1/100,000 population for several years, but show a slightly upward trend over more than 40-year period (1970-2012). A return to the typical prevalence of serogroup B accounting for up to 75% of cases has recently been shown. In this context, the upward trend in IMD caused by serogroup Y associated with a high case fatality rate in the Czech Republic cannot be overseen or even underestimated. The hypervirulent clonal complex cc11 characteristic of N.m.C:2a:P1.2,5 prevailed in this country between 1993 and 2004, but decreased in the following years and currently, hypervirulent clonal complexes characteristic of N.m.B (cc18, cc32, cc41/44, and cc269) are the most common in the Czech Republic. The average overall case fatality rate in the Czech Republic is 10%, but varies between causative serogroups: the highest case fatality rate has been caused by serogroup Y (16.7% ), followed by serogroup C (12.3%), and serogroup W135 (11.7%), while serogroup B only accounts for a case fatality rate of 7.8%. In the age group under one year, the incidence of IMD caused by serogroup B remains three to five times as high as in the age groups 1-4 years and 15-19 years throughout the surveillance period. The highest numbers of IMD cases caused by serogroup B have been reported in 3-7-month-olds. Based on the IMD surveillance data from the Czech Republic, the NRL recommends a vaccination strategy to provide an adequate protection to individuals. To induce an immune response as wide as possible, the tetravalent meningococcal conjugate vaccine A,C,Y,W135 in combination with the newly registered MenB vaccine designed by reverse vaccinology should be given. To maintain immunity, subsequent booster doses are required at intervals depending on the primary vaccination age.

The rate of population increase of three mite species, Acarus siro (L.), Lepidoglyphus destructor (Schrank) and Tyrophagus putrescentiae (Schrank), was studied on various types of barley and at various combinations of temperature and humidity. The mites were added into the chambers and incubated for 21 days on seven different kinds of barley coming from four sites, including six cultivars and a mixture. The population increase of all species was higher on the mixture than on any other cultivar, except for Sebastian and Calgary. The increase of mites was studied at constant temperatures ranging from 5 to 35 °C and relative humidity (RH) ranging from 50 to 90 %. Positive rate of increase was found above 70 % RH for all species. The optimal humidity was at 85 % RH for A. siro and L. destructor and at 90 % RH for T. putrescentiae. As concerns the temperature, positive rate of increase was found at temperatures higher than 10, 15 and 20 °C for A. siro, L. destructor and T. putrescentiae, respectively. The temperature optima were at 23, 25, and 30 °C for A. siro, L. destructor and T. putrescentiae, respectively. Model estimated on laboratory data was then fitted to temperature and humidity records from August to November in the Czech grain store. Estimated population rate of increase was rarely positive: for A. siro it was for 24 %, for L. destructor for only 1 % and for T. putrescentiae for only 7 % days of the study period. It is concluded that in the climatic conditions of the Czech Republic the population increase of three mite pests is negligible during autumn and winter.

Random Distribution Pattern and Non-adaptivity of Genome Size in a Highly Variable Population of Festuca pallens

Šmarda, Petr; Bureš, Petr; Horová, Lucie

2007-01-01

Background and Aims The spatial and statistical distribution of genome sizes and the adaptivity of genome size to some types of habitat, vegetation or microclimatic conditions were investigated in a tetraploid population of Festuca pallens. The population was previously documented to vary highly in genome size and is assumed as a model for the study of the initial stages of genome size differentiation. Methods Using DAPI flow cytometry, samples were measured repeatedly with diploid Festuca pallens as the internal standard. Altogether 172 plants from 57 plots (2·25 m2), distributed in contrasting habitats over the whole locality in South Moravia, Czech Republic, were sampled. The differences in DNA content were confirmed by the double peaks of simultaneously measured samples. Key Results At maximum, a 1·115-fold difference in genome size was observed. The statistical distribution of genome sizes was found to be continuous and best fits the extreme (Gumbel) distribution with rare occurrences of extremely large genomes (positive-skewed), as it is similar for the log-normal distribution of the whole Angiosperms. Even plants from the same plot frequently varied considerably in genome size and the spatial distribution of genome sizes was generally random and unautocorrelated (P > 0·05). The observed spatial pattern and the overall lack of correlations of genome size with recognized vegetation types or microclimatic conditions indicate the absence of ecological adaptivity of genome size in the studied population. Conclusions These experimental data on intraspecific genome size variability in Festuca pallens argue for the absence of natural selection and the selective non-significance of genome size in the initial stages of genome size differentiation, and corroborate the current hypothetical model of genome size evolution in Angiosperms (Bennetzen et al., 2005, Annals of Botany 95: 127–132).

The management of high-level waste in Czech Republic have a very short history, because before the year 1989 spent nuclear fuel was re-exported back to USSR. The project ``Geological research of HLW repository in Czech Republic`` was initiated during 1990 by the Ministry of the Environment of the Czech Republic and by this project delegated the Czech Geological Survey (CGU) Prague. The first CGU project late in 1990 for multibarrier concept has proposed a geological repository to be located at a depth of about 500 m. Screening and studies of potential sites for repository started in 1991. First stage representedmore » regional siting of the Czech Republic for perspective rock types and massifs.

This work in the Czech Republic was possible thanks to the detailed geological studies done in the past and thanks to the numerous archive data, concentrated in the central geological archive GEOFOND. Selection of perspective sites also respected natural conservation regions, regions conserving water and mineral waters resources. CGU opened up contact with countries with similar geological situation and started cooperation with SKB (Swedish Nuclear Fuel and Waste Management Co.). The Project of geological research for the next 10 years is a result of these activities.« less

[The importance of the Czech Medical Society yesterday and today].

Fourteen physicians headed by Jan Evangelista Purkynĕ signed the proposed by-laws of the Czech medical society in october 1861. Emperor's approval was received 26th june 1862 and in july Purkynĕ was elected the first president. The same illuminated personalities were the founders of the Casopis lékarů ceských--the Czech medical Journal which has remained the most important Czech periodical until the present time. The aims of the Society were to cultivate medical science and promote Czech language in medicine. Weekly scientific sessions, medical periodical and publication of monographs related to medicine were the means how to achieve the aims. The Czech Medical Society became soon the centre of medical science in Bohemia. Its members were among the foremost fighters for the use of Czech language in Charles university and their relentless effort helped much to the establishment of the Czech Univerzity in 1882 and Czech medical faculty a year later. In subsequent years the Society was also involved in professional problems related to social health insurance, medical fees, ethical problems and other relevant questions such as the establishment of medical chambers. The activity of the Czech medical Society was never interrupted during its 130 years of existence, although there were several difficult periods in its life, mainly during the first and second world war and also in the past 40 years. In spite of the atomization of medicine the Czech medical Society has been continuing its eminent mission to create communication and establish close links between the medical science and practical medicine by systematically bringing new knowledge in medicine and biology to general physicians and by putting together physicians, surgeons and basic scientists. The task for the future is seen in optimal transfer of new knowledge and ideas from scientists to practicians and vice versa; and to take care of the highest possible moral and ethical standard required for humane medicine. Tradition and achievements of our teachers is binding and we are looking forward to better future in united Europe.

In recent decades gamete donation has received growing attention. Data from the Czech National Registry of Assisted Reproduction show that the number of cycles using donated oocytes has been increasing every year. According to Czech law, gamete donation is anonymous. Since 2011, some members of the Czech parliament have repeatedly made requests to revoke the anonymity but anonymity is one of the preconditions for such donation in this country. The aim of this study was to find out how the gamete recipients feel towards informing their child about the circumstances of their conception and their access to the identity of the donor. A total of 195 recipients (122 women undergoing treatment - 43 Czechs, 79 foreigners (Western Europe and the USA) and 73 male partners - 28 Czechs, 45 foreigners) participated in this survey. The data were obtained by anonymous questionnaire. A significant difference between the attitude of the future Czech and foreign parents regarding disclosing the mode of conception was found (P = 0.003). The vast majority of Czechs were against disclosure. The foreign recipients were somewhat more divided. Regarding the donor's identity, there was no difference in atttitude between the groups. Recipients rarely consider that the knowledge of the donor's identity will be important for their child. The recipients overall, were convinced that the psychological aspects of parenting are far more important to the child than genetics, and see no reasons for disclosing the donor´s identity. While the the foreign recipients were less adamant about non-disclosure, the overall finding was in accord with the current Czech law on anonymity and not in agreement with the proposed abolition. The recipient's attitudes towards disclosing were also culturally determined. The fact that some countries have revised their rules towards open idendity is not a rationale for such change in the Czech Republic.

Despite efforts to expand global physical activity (PA) surveillance data to include both low- and high-income countries worldwide, our understanding of the relationship between PA and quality of life (QOL) in older adults from culturally diverse backgrounds is limited. We tested McAuley's social-cognitive model of the PA-QOL relationship in the cultural context of the Czech Republic, a post-communist central European country. A total of 546 older Czech adults (mean age 68 years) completed a battery of questionnaires assessing indicators of PA, self-efficacy, health status, and global QOL. A structural equation model was used to test the relationship between PA and QOL. The model hypothesized an indirect relationship between PA and QOL: PA predicted self-efficacy, which in turn predicted global QOL through mental and physical health status. The analyses indicated an acceptable fit of the proposed model, albeit with different emphases than those of studies from Western countries. Above all, we observed a stronger effect of PA on self-efficacy and a weaker mediating effect of health status on the PA-QOL relationship. Our findings supported the validity of McAuley's PA-QOL social-cognitive model for a non-Western cultural context. However, it seems that self-efficacy and health status may influence the PA-QOL relationship in this population in a manner different from that proposed in McAuley's model.

The study examines spatial patterns of effects of high temperature extremes on cardiovascular mortality in the Czech Republic at a district level during 1994–2009. Daily baseline mortality for each district was determined using a single location-stratified generalized additive model. Mean relative deviations of mortality from the baseline were calculated on days exceeding the 90th percentile of mean daily temperature in summer, and they were correlated with selected demographic, socioeconomic, and physical-environmental variables for the districts. Groups of districts with similar characteristics were identified according to socioeconomic status and urbanization level in order to provide a more general picture than possible on the district level. We evaluated lagged patterns of excess mortality after hot spell occurrences in: (i) urban areas vs. predominantly rural areas; and (ii) regions with different overall socioeconomic level. Our findings suggest that climatic conditions, altitude, and urbanization generally affect the spatial distribution of districts with the highest excess cardiovascular mortality, while socioeconomic status did not show a significant effect in the analysis across the Czech Republic as a whole. Only within deprived populations, socioeconomic status played a relevant role as well. After taking into account lagged effects of temperature on excess mortality, we found that the effect of hot spells was significant in highly urbanized regions, while most excess deaths in rural districts may be attributed to harvesting effects.

The purpose of this study was to report predictors and prevalence of home and workplace smoking bans in 5 European countries. We conducted a population-based telephone survey of 4977 women, ascertaining factors associated with smoking bans. Odds ratios (ORs) and 95% confidence intervals (CI) were derived using unconditional logistic regression. A complete home smoking ban was reported by 59.5% of French, 63.5% of Irish, 61.3% of Italian, 74.4% of Czech, and 87.0% of Swedish women. Home smoking bans were associated with younger age and being bothered by secondhand smoke, and among smokers, inversely associated with greater tobacco dependence. Among nonsmokers, bans were also related to believing smoking is harmful (OR=1.20, CI: 1.11, 1.30) and having parents who smoke (OR=0.62, CI: 0.52, 0.73). Workplace bans were reported by 92.6% of French, 96.5% of Irish, 77.9% of Italian, 79.1% of Czech, and 88.1% of Swedish women. Workplace smoking bans were reported less often among those in technical positions (OR=0.64, CI: 0.50, 0.82) and among skilled workers (OR=0.53, CI: 0.32, 0.88) than among professional workers. Workplace smoking bans are in place for most workers in these countries. Having a home smoking ban was based on smoking behavior, demographics, beliefs, and personal preference. PMID:19926747

To the Editor, Drug utilization is an important field of drug policy and an integral part of public health internationally. This area of research attracts increasing interest but the pioneering work was done 50 years ago when the first drug consumption report from six European countries for the period of 1966-1967 showed great differences in drug utilization between population groups (WHO, 1968). These results gave important stimulus for creation of Anatomical Therapeutic Chemical (ATC) classification and technical unit of measurement called the Defined Daily Dose (DDD) which is specified as "the assumed average maintenance dose per day for a drug used for its main indication in adults" that dealt with the objections against traditional units of measurement in drug utilization studies (WHO, 2016). The ATC/DDD methodology has in the meantime proved its suitability in drug utilization monitoring and research. As mentioned previously, consumption of pharmaceuticals is often used as a basis for comparison between countries. Based on our professional expertise, we decided to analyze the consumption of cardiovascular medicines by DDD in the Czech Republic and Slovak Republic within all ATC groups reported to OECD (OECD, 2016a). According to OECD indicator results, the Slovak Republic showed in 2014 a higher pharmaceutical consumption by DDD in ATC group C (cardiovascular system) compared to the Czech Republic (OECD, 2016a).

Human alveolar echinococcosis (AE) is caused by larval stages of the tapeworm Echinococcus multilocularis. In the Czech Republic, screening tests to detect the specific infectious agent have been performed since 1998. The first AE cases were diagnosed in 2007, and until 2014, a total of 21 diseases were recorded. In accordance with radiological, histological, and/or PCR data, serological examinations of 699 individuals helped to reveal 15 additional AE cases in the period of 2015-2016. From the cumulative data for 1998-2016, it appears that of 2,695 patients examined, 36 (18 men and 18 women) were diagnosed with AE. Their age at diagnosis ranged from 20 to 82 years and was lower for women (mean 43.7, median 39.5) than for men (50.9 and 57.5, respectively), but the difference was not statistically significant. In the period of 2007-2016, the mean annual incidence rate was 0.034 cases/100 000 population. Our study indicates an ongoing increase in AE cases. The disease can be autochthonous in nature, as evidenced not only by some case history data but also by the detection of the larval stages in wild boar (Sus scrofa). AE risk to humans in the Czech Republic is discussed in the context of the known data on the presence of various parasite developmental stages in animals.

To map the recent prevalence of alcohol and other psychoactive substances in deceased victims of traffic accidents in the Czech Republic. The studied sample consisted of individuals autopsied in the departments of forensic medicine who died during traffic accidents in 2008 and were toxicologically tested for one or more of the following substances: ethanol, volatile substances, cannabis, opiates, stimulants, cocaine, benzodiazepines, and barbiturates. Case definition involved alcohol cases with blood alcohol concentration (BAC) 0.2 g/kg and higher; with cannabis, detections of active THC metabolites only were taken into account; from cases where volatile substances (solvents) were detected we included into the positive cases only those where substances were not produced post mortem or in some physiological or pathological statuses. The sample consisted of 1,040 persons deceased in traffic accidents, of whom 582 (56.0%) were toxicologically tested for one or more of the substances listed above. The sample has been divided into two subsamples--one of 778 (74.8%) active participants of road traffic accidents (pedestrians, bicyclists, and drivers) and other subsample consisting of 262 (25.4%) non-active participants. Ethanol was found in 38.3% of 381 tested and at least one of other psychoactive substances was found in 11.7% of 384 tested active participants--of those, stimulants (mostly methamphetamine) were found most frequently (6.5% of 337 tested), cannabis (5.9% of 203 tested) and benzodiazepines (3.9% of 363 tested active participants). Drivers were positive for ethanol in 29.2% cases, for one or more of other psychoactive substances except ethanol in 12.7% cases, most frequently for stimulants (9.2%) and cannabis (6.2%). Professional drivers were found negative for ethanol and other psychoactive substance except of one case of methamphetamine (6.7%). The study confirms high prevalence of alcohol and other psychoactive substances, especially stimulants (methamphetamine), cannabis and benzodiazepines, among deceased participants of road traffic accidents including drivers in the Czech Republic.

The aim of this project was to launch a new Food Composition Database (FCDB) Programme in the Czech Republic; to implement a methodology for food description and value documentation according to the standards designed by the European Food Information Resource (EuroFIR) Network of Excellence; and to start the compilation of a pilot FCDB. Foods for the initial data set were selected from the list of foods included in the Czech Food Consumption Basket. Selection of 24 priority components was based on the range of components used in former Czech tables. The priority list was extended with components for which original Czech analytical data or calculated data were available. Values that were input into the compiled database were documented according to the EuroFIR standards within the entities FOOD, COMPONENT, VALUE and REFERENCE using Excel sheets. Foods were described using the LanguaL Thesaurus. A template for documentation of data according to the EuroFIR standards was designed. The initial data set comprised documented data for 162 foods. Values were based on original Czech analytical data (available for traditional and fast foods, milk and milk products, wheat flour types), data derived from literature (for example, fruits, vegetables, nuts, legumes, eggs) and calculated data. The Czech FCDB programme has been successfully relaunched. Inclusion of the Czech data set into the EuroFIR eSearch facility confirmed compliance of the database format with the EuroFIR standards. Excel spreadsheets are applicable for full value documentation in the FCDB.

Czech Republic to Become Member of ESO

Today, an agreement was signed in Prague between ESO and the Czech Republic, aiming to make the latter become a full member of ESO as of 1 January 2007. "The future membership of the Czech Republic in ESO opens for the Czech astronomers completely new opportunities and possibilities. It will foster this discipline on the highest quality level and open new opportunities for Czech industry to actively cooperate in research and development of high-tech instruments for astronomical research," said Miroslava Kopicová, Minister of Education, Youth and Sports of the Czech Republic. ESO PR Photo 52/06 ESO PR Photo 52/06 Signing Ceremony "We warmly welcome the Czech Republic as the thirteenth member of ESO," said Catherine Cesarsky, ESO's Director General. "The timing couldn't be better chosen: with the Very Large Telescope, Europe is now at the forefront of ground-based astronomy, and with the construction of ALMA and the final studies for the European Extremely Large Telescope, we will ensure that this will remain so for several decades. We look forward to working together with our Czech colleagues towards these successes." The signing event took place at the Czech Ministry of Education, Youth and Sports in Prague. Following ratification by the Czech Parliament, the Czech Republic with thus join the twelve present member states of ESO, the European Organisation for Astronomical Research in the Southern Hemisphere: Belgium, Denmark, France, Finland, Germany, Italy, the Netherlands, Portugal, Spain, Sweden, Switzerland and the United Kingdom. The Czech Republic is the first country from Central and Eastern Europe to join ESO. Astronomy in the Czech Republic has a very long tradition that dates from as far back as 3500 BC. Four centuries ago, Tycho Brahe and Johannes Kepler established themselves in Prague at the invitation of the emperor Rudolph II, laying the ground for the first golden age in astronomy. Later, eminent scientists such as Christian Doppler, Ernst Mach and Albert Einstein stayed in the famous city for periods of time. The Czech capital also played host to the General Assembly of the International Astronomical Union, first in 1967 and, more recently, in August 2006. Astronomy in the Czech Republic is shared between the Astronomical Institute of the Academy of Sciences and several leading universities, in Prague, Brno and Opava, among others. The Astronomical Institute operates the Ondrejov Observatory, with a 2-m optical telescope and a 10-m radio telescope. Czech astronomers are very active in many fields of this science, such as solar and stellar physics, and the study of interstellar matter, galaxies and planetary systems. Created in 1962, ESO, which quite fittingly means 'ace' in the Czech language, provides state-of-the-art research facilities to European astronomers and astrophysicists. ESO's activities cover a wide spectrum including the design and construction of world-class ground-based observational facilities for the member-state scientists, large telescope projects, design of innovative scientific instruments, developing new and advanced technologies, furthering European co-operation and carrying out European educational programmes. Whilst the Headquarters are located in Garching near Munich, Germany, ESO operates three observational sites in the Chilean Atacama desert. The Very Large Telescope (VLT) is located on Paranal, a 2 600m high mountain south of Antofagasta. At La Silla, 600 km north of Santiago de Chile at 2 400m altitude, ESO operates several medium-sized optical telescopes. The third site is the 5 000m high Llano de Chajnantor, near San Pedro de Atacama. Here a new submillimetre telescope (APEX) is in operation, and a giant array of 12-m submillimetre antennas (ALMA) is under development. Over 1 600 proposals are made each year for the use of the ESO telescopes.

The influence of mutation, recombination, population history, and selection on patterns of genetic diversity in Neisseria meningitidis.

Patterns of genetic diversity within populations of human pathogens, shaped by the ecology of host-microbe interactions, contain important information about the epidemiological history of infectious disease. Exploiting this information, however, requires a systematic approach that distinguishes the genetic signal generated by epidemiological processes from the effects of other forces, such as recombination, mutation, and population history. Here, a variety of quantitative techniques were employed to investigate multilocus sequence information from isolate collections of Neisseria meningitidis, a major cause of meningitis and septicemia world wide. This allowed quantitative evaluation of alternative explanations for the observed population structure. A coalescent-based approach was employed to estimate the rate of mutation, the rate of recombination, and the size distribution of recombination fragments from samples from disease-associated and carried meningococci obtained in the Czech Republic in 1993 and a global collection of disease-associated isolates collected globally from 1937 to 1996. The parameter estimates were used to reject a model in which genetic structure arose by chance in small populations, and analysis of molecular variation showed that geographically restricted gene flow was unlikely to be the cause of the genetic structure. The genetic differentiation between disease and carriage isolate collections indicated that, whereas certain genotypes were overrepresented among the disease-isolate collections (the "hyperinvasive" lineages), disease-associated and carried meningococci exhibited remarkably little differentiation at the level of individual nucleotide polymorphisms. In combination, these results indicated the repeated action of natural selection on meningococcal populations, possibly arising from the coevolutionary dynamic of host-pathogen interactions.

Lead isotope ratios in tree bark pockets: an indicator of past air pollution in the Czech Republic.

Tree bark pockets were collected at four sites in the Czech Republic with differing levels of lead (Pb) pollution. The samples, spanning 1923-2005, were separated from beech (Fagus sylvatica) and spruce (Picea abies). Elevated Pb content (0.1-42.4 microg g(-1)) reflected air pollution in the city of Prague. The lowest Pb content (0.3-2.6 microg g(-1)) was found at the Kosetice EMEP "background pollution" site. Changes in (206)Pb/(207)Pb and (208)Pb/(206)Pb isotope ratios were in agreement with operation times of the Czech main anthropogenic Pb sources. Shortly after the Second World War, the (206)Pb/(207)Pb isotope ratio in bark pockets decreased from 1.17 to 1.14 and the (208)Pb/(206)Pb isotope ratio increased from 2.12 to 2.16. Two dominant emission sources responsible for these changes, lignite and leaded petrol combustion, contributed to the shifts in Pb isotope ratios. Low-radiogenic petrol Pb ((206)Pb/(207)Pb of 1.11) lead to lower (206)Pb/(207)Pb in bark pockets over time. High-radiogenic lignite-derived Pb ((206)Pb/(207)Pb of 1.18 to 1.19) was detected in areas affected by coal combustion rather than by traffic.

Svačina, Štěpán; Ovesná, Petra; Kuhn, Matyáš; Nováčková, Martina

Type 2 diabetes is an enormous medical problem caused by increasing prevalence of the disease and increasing prevalence of severe chronic complications of diabetes. New ADA/EASD guidelines and also Czech diabetes society guidelines enable effective individual approach to the patient. Goal of the therapy is optimal compensation of diabetes and prevention of acute and chronic complications of diabetes and decrease of mortality. Diabetes therapy is started by education in diet a regime combined with metformin. According to the progressive character of the disease it is usually necessary to intensify the therapy by adding antidiabetics from other groups. This study was proposed to analyse the use of therapy algorithm in Czech Republic in patients with insufficient metformin therapy. Secondary objectives were to describe level of compensation of diabetes in time and level of components of the metabolic syndrome in different treatment combinations.Methodic and results: In the sample of 1 516 patients, frequency of use of antidiabetic medication after metformin it was gliflozins 33% and gliptins 28% in the first phase of the study and the number increased later during the study. Median of HbA1c in the beginning of the study was 65 mmol/mol, greatest decrease was found in patents using combination of incretine analogs with metformin - 89 % of them had the HbA1c level < 60 mmol/mol. The study showed also that antidiabetic drugs used after metformin in Czech Republic are very effective in reducing weight, and improving blood pressure and lipid profile. Therapy using combination of metformin with gliflozins, gliptins or incretin analogs is most effective when metformin is not effective enough.Key words: diabetes type 2 - gliflozins - gliptins - incretine analogs - metformin therapy failure.

Overweight and obesity in adolescents is associated with many health risks and considerable direct and indirect healthcare costs. The purpose of this study is to examine trends in the prevalence of overweight and obesity in 11-, 13- and 15-year-old adolescents in the Czech Republic from 1998 to 2014. Data from five self-reported survey rounds (1998, 2002, 2006, 2010, and 2014) of the Health Behaviour in School-aged Children Study (HBSC) were used to assess trends in overweight and obesity among Czech adolescents. The total sample consisted of 19,103 adolescents (51.2% girls). A logistic regression analysis was used to assess trends in different age and gender categories. From 1998 to 2014 a significant increase in the prevalence of overweight and obesity was observed among boys in all age categories (11 years old 22.2% 1998 - 28.3% 2014 ; 13 years old 17.9% 1998 - 26.7% 2014 ; 15 years old 9.8% 1998 - 20.8% 2014 ) and among 15-year-old girls (6.0% 1998 - 10.9% 2014 ). None of the age and gender categories showed an overall decrease over the 16-year period. In boys, the prevalence of overweight was significantly higher with steeper negative trends compared with girls. However, stabilization in overweight rates was observed between 2010 and 2014 in all age and gender groups. Nationally representative self-reported data show a significant increase in overweight (including obesity) prevalence among children from 1998 to 2014 in the Czech Republic. The results also suggest stabilization in overweight prevalence between 2010 and 2014. Continuing research is needed to determine future trends while interventions aimed at reducing overweight and obesity in children should be implemented on different levels of public policy.

Peri-urbanisation, counter-urbanisation, and an extension of residential exposure to ticks: a clue to the trends in Lyme borreliosis incidence in the Czech Republic?

PubMed

Zeman, Petr; Benes, Cestmir

2014-10-01

The incidence of tick-borne human diseases (TBD) in the Czech Republic (CZ) is on the increase, driven by infections increasingly acquired in residential locations, earlier in spring and later in autumn, and among children and the elderly. To interpret these trends, data on Lyme borreliosis (LB) incidence between 1997 and 2010 were analysed in the context of population migration flows registered in the CZ during the same period. Analysis showed that a migration stream of families with children, and of the elderly, flowed from more urbanized and densely populated localities to those more rural and less populated, where the chance of acquiring LB in the home vicinity was greater than in the urban settings. By contrast, a stream of people in the life phase between early adulthood and family formation flowed reversely, corresponding to a prominent absence of this age category from the patient spectrum. The data further showed that the more the residential exposure became prevalent, the more people were in year-round (rather than in summertime only) contact with ticks, which accounts for an extension of the cases' seasonal distribution as well as for an overall increase in case numbers. Finally, the fact that majority of the urban-to-rural migrants could be categorised as wealthier people could explain the previously noticed lack of low-status people among TBD patients in the CZ.

To assess the importance of wild birds as a reservoir of zoonotic pathogens in Austria and the Czech Republic, we sampled 1,325 wild birds representing 13 orders, 32 families, and 81 species. The majority belonged to orders Columbiformes (43%), Passeriformes (25%), and to birds of prey: Accipitriformes, Strigiformes, and Falconiformes (15%). We collected cloacal swabs from 1,191 birds for bacterial culture and 1,214 triple swabs (conjunctiva, choana, cloaca) for DNA and RNA isolation. The cloacal swabs were processed by classical bacteriologic methods for isolation of Escherichia coli , Salmonella spp., methicillin-resistant Staphylococcus aureus (MRSA), and thermophilic Campylobacter spp. Nucleic acids isolated from triple swabs were investigated by PCR for West Nile virus, avian influenza viruses, and Chlamydia spp. We also tested tissue samples from 110 fresh carcasses for Mycobacterium spp. by PCR and we cultured fresh droppings from 114 birds for Cryptococcus spp. The most-frequently detected zoonotic bacteria were thermophilic Campylobacter spp. (12.5%) and Chlamydia spp. (10.3%). From 79.2% of the sampled birds we isolated E. coli , while 8.7% and 0.2% of E. coli isolates possessed the virulence genes for intimin (eaeA) and Shiga toxins (stx 1 and stx 2 ), respectively. Salmonella spp. were rarely found in the sampled birds (2.2%), similar to findings of MRSA (0.3%). None of the samples were positive for Cryptococcus neoformans , Mycobacterium spp., avian influenza viruses, or West Nile virus.

The purpose of this study was to analyze pressure injury (PI) occurrence upon admission and at any time during the hospital course inpatients care facilities in the Czech Republic. Secondary aims were to evaluate demographic and clinical data of patients with PI and the impact of a PI on length of stay (LOS) in the hospital. Retrospective, cross-sectional analysis. The sample comprised data of hospitalized patients entered into the National Register of Hospitalized Patients (NRHOSP) database of the Czech Republic between 2007 and 2014 with a diagnosis L89 (pressure ulcer of unspecified site based on the International Classification of Diseases, Tenth Revision, ICD-10). Electronic records of 17,762,854 hospitalizations were reviewed. Data from the NRHOSP from all acute and non-acute care hospitals in the Czech Republic were analyzed. Specifically, we analyzed patients admitted to acute and non-acute care facilities with a primary or secondary diagnosis of PI. The NRHOSP database included 17,762,854 cases, of which 46,224 cases (33,342 cases in acute care hospitals; 12,882 in non-acute care hospitals) had the L89 diagnosis (0.3%). The mean age of patients admitted with a PI was 73.8 ± 15.3 years (mean ± SD), and their average LOS was 33.2 ± 76.9 days. The mean LOS of patients hospitalized with L89 code as a primary diagnosis (n = 6877) was significantly longer compared to those patients for whom L89 code was a secondary diagnosis (25.8 vs 20.2 days, P < .001) in acute care facilities. In contrast, we found no difference in the mean LOS for patients hospitalized in non-acute care facility (58.7 days vs 65.1 days; P = .146) with ICD code L89. Pressure injuries were associated with significant LOS in both acute and non-acute care settings in the Czech Republic. Despite the valuable insights we obtained from the analysis of NRHOSP data, we advocate creation of a more valid and reliable electronic reporting system that enables policy makers to evaluate the quality and safety concerning PI and its impact on patients and the healthcare system.

This research article uses the experiences from the initiative of active working group „WG#03: BIM & Realization“, which is the part of the Czech BIM Council, especially the document called “Draft of unified data structure for Building Information Modeling in the Czech Republic”. The findings of this paper are in the defining specific Level of Development of relative parameters, mentioned in this document, connected to the specific level of information and details requested by the Czech Republic’s Legislation. These findings could be used as an underlay to create document called “Level of Development draft assignment to the individual stages of project documentation in the Czech Republic”. The Level of Development is the most useful way of the information visualization, which leads to the most effortless way of exact stated implementation of Building Information Modeling into the practice of designing structures and buildings in the Czech Republic. The Implementation of using Building Information Modeling technology in designing structures and buildings will lead to the enhanced quality of the project documentation and generally to more effective cost savings during whole life cycle of buildings. Moreover, the all over using of the BIM technology in the Czech Republic will be very useful in the Facility Management area, especially in the facility management and maintenance of state buildings.

To assess the classification, repair, and follow up of extensive obstetric perineal injuries in the Czech and Slovak Republics. A survey conducted in 2009 using questionnaires distributed to obstetric departments regarding classification and management of obstetric perineal injuries. Although 15 centers in the Czech Republic and 2 in the Slovak Republic indicated use of a 4-degree classification system, none of these centers reported using the classification accepted by the Royal College of Obstetricians and Gynaecologists. Use of a 3-degree classification system in accordance with definitions in Czech textbooks was reported by 14 Czech and 3 Slovak maternity hospitals. There was significant heterogeneity in clinical practice regarding techniques to repair extensive obstetric perineal injuries, antibiotic prophylaxis, early postpartum care, and follow up. There is great inconsistency in the classification and management of extensive obstetric perineal injuries. Uniform recommendations should be created and accepted, not only in the Czech and Slovak Republics, but worldwide. Copyright 2010 International Federation of Gynecology and Obstetrics.

Estimating polymorphic allele frequencies of the NADPH-CYP450 oxidoreductase (POR) gene in a Czech Slavic population. The POR gene was analyzed in 322 individuals from a control cohort by sequencing and high resolution melting analysis. We identified seven unreported SNP genetic variations, including two SNPs in the 5' flanking region (g.4965C>T and g.4994G>T), one intronic variant (c.1899-20C>T), one synonymous SNP (p.20Ala=) and three nonsynonymous SNPs (p.Thr29Ser, p.Pro384Leu and p.Thr529Met). The p.Pro384Leu variant exhibited reduced enzymatic activities compared with wild-type. New POR variant identification indicates the number of uncommon variants might be specific for each subpopulation being investigated, particularly germane to the singular role that POR plays in providing reducing equivalents to all CYP450s in the endoplasmic reticulum.

The decline of physical activity (PA) in adults as well as children and youth is a worldwide phenomenon. The aim of this study is to analyse the amount of PA in Czech university students' daily lives. The research on university students was conducted as part of nationwide research on PA in the adult population of the Czech Republic. A total of 906 students at eight selected universities were asked to participate in this study. The response rate was 79.5%. We analysed data from 641 university students: 318 male [mean age 21.63 ± 1.73; mean Body Mass Index (BMI) 23.50 ± 1.91] and 323 female (mean age 21.08 ± 1.53; mean BMI 21.23 ± 2.20). The students wore Yamax SW-701 pedometers continuously for seven days. With respect to BMI, the recommendation of 10,000 steps per day on an average day was met by 76% of men and 68% of women of normal weight, 67% of male students who were overweight or obese and 85% of female students who were overweight or obese. Of all monitored days, in both females and males, the number of steps taken on Sunday was significantly lower (p<0.0001) in comparison to other days of a week. No significant differences were found in the number of steps taken among students of normal weight, students who were overweight and students who were obese on any of the monitored days. The majority of Czech male university students are of normal weight. Only 9% of students meet the criterion of 10,000 steps every day. Approximately two-thirds of students meet the 10,000 steps daily criterion on four or more days per week. The lowest number of steps is taken on Sundays; this finding supports the need for intervention programmes to enhance PA on weekends.

Breast cancer screening in the Czech Republic: time trends in performance indicators during the first seven years of the organised programme

PubMed Central

2011-01-01

Background The Czech Breast Cancer Screening Programme (CBCSP) was initiated in September 2002 by establishing a network of accredited centres. The aim of this article is to describe progress in the programme quality over time after the inception of the organised programme. Methods The CBCSP is monitored using an information system consisting of three principal components: 1) the national cancer registry, 2) a screening registry collecting data on all screening examinations, further assessments and final diagnoses at accredited programme centres, and 3) administrative databases of healthcare payers. Key performance indicators from the European Guidelines have been adopted for continuous monitoring. Results Breast cancer incidence in the Czech Republic has steadily been increasing, however with a growing proportion of less advanced stages. The mortality rate has recently stabilised. The screening registry includes 2,083,285 records on screening episodes between 2002 and 2008. In 2007-2008, 51% of eligible women aged 45-69 were screened. In 2008, the detection rates were 6.1 and 3.7 per 1,000 women in initial and subsequent screening respectively. Corresponding recall rates are 3.9% and 2.2%, however, it is necessary to pay attention to further assessment performed during the screening visits. Benign to malignant open biopsy ratio was 0.1. Of invasive cases detected in screening, 35.6% was less than 10 mm in diameter. Values of early performance indicators, as measured by both crude and standardized estimates, are generally improving and fulfil desirable targets set by European Guidelines. Conclusions Mammography screening in the Czech Republic underwent successful transformation from opportunistic prevention to an organised programme. Values of early indicators confirm continuous improvement in different aspects of process quality. Further stimulation of participation through invitation system is necessary to exploit the full potential of screening mammography at the population level. PMID:21554747

Objectives Uranium miners are chronically exposed to radon and its progeny, which are known to cause lung cancer and may be associated with leukemia. This study was undertaken to evaluate risk of non-lung solid cancers among uranium miners in Příbram region, Czech Republic. Methods A retrospective stratified case-cohort study in a cohort of 22,816 underground miners who were employed between 1949 and 1975. All incident non-lung solid cancers were ascertained among miners who worked underground for at least 12 months (n = 1020). A subcohort of 1707 subjects was randomly drawn from the same population by random sampling stratified on age. The follow-up period lasted from 1977 to 1996. Results Relative risks comparing 180 WLM (90th percentile) of cumulative lifetime radon exposure to 3 WLM (10th percentile) were 0.88 for all non-lung solid cancers combined (95% CI 0.73 – 1.04, n = 1020), 0.87 for all digestive cancers (95% CI 0.69 – 1.09, n = 561), 2.39 for gallbladder cancer (95% CI 0.52 – 10.98, n = 13), 0.79 for larynx cancer (95% CI 0.38 – 1.64, n = 62), 2.92 for malignant melanoma (95% CI 0.91 – 9.42, n = 23), 0.84 for bladder cancer (95% CI 0.43 – 1.65, n = 73), and 1.13 for kidney cancer (95% CI 0.62 – 2.04, n = 66). No cancer type was significantly associated with radon exposure; only malignant melanoma and gallbladder cancer showed elevated but non-significant association with radon. Conclusions Radon was not significantly associated with incidence of any cancer of interest, although a positive association of radon with malignant melanoma and gallbladder cancer cannot be entirely ruled out.

Colorectal cancer (CRC) is a complex disease related to environmental and genetic risk factors. Several studies have shown that susceptibility to complex diseases can be mediated by ancestral alleles. Using RNAi screening, CTNNBL1 was identified as a putative regulator of the Wnt signaling pathway, which plays a key role in colorectal carcinogenesis. Recently, single nucleotide polymorphisms (SNPs) in CTNNBL1 have been associated with obesity, a known risk factor for CRC. We investigated whether genetic variation in CTNNBL1 affects susceptibility to CRC and tested for signals of recent selection. We applied a tagging SNP approach that cover all known common variation in CTNNBL1 (allele frequency >5%; r2>0.8). A case-control study was carried out using two well-characterized study populations: a hospital-based Czech population composed of 751 sporadic cases and 755 controls and a family/early onset-based German population (697 cases and 644 controls). Genotyping was performed using allele specific PCR based TaqMan® assays (Applied Biosystems, Weiterstadt, Germany). In the Czech cohort, containing sporadic cases, the ancestral alleles of three SNPs showed evidence of association with CRC: rs2344481 (OR 1.44, 95%CI 1.06-1.95, dominant model), rs2281148 (OR 0.59, 95%CI 0.36-0.96, dominant model) and rs2235460 (OR 1.38, 95%CI 1.01-1.89, AA vs. GG). The associations were less prominent in the family/early onset-based German cohort. Data derived from several databases and statistical tests consistently pointed to a likely shaping of CTNNBL1 by positive selection. Further studies are needed to identify the actual function of CTNNBL1 and to validate the association results in other populations. PMID:21537400

Trace elements in certain amounts are essential for childrens' health, because they are present in tissues participating in metabolic reactions of organisms. Deficiency of the essential elements may result in malnutrition, impaired body immunity, and poor resistance to disease. These conditions might be enhanced against a background of additional adverse environmental factors such as toxic elements. The analysis of elements in childrens' hair will give information on the deficiency of essential elements and excess of toxic elements in relation to their diet. In this study, 141 hair samples from children (girls and boys) living in two regions of Tanzanian mainland (Dar es Salaam and Moshi) and the island of Zanzibar have been analysed for trace elements in relation to food consumption habits. The analysis was carried out using long and short irradiation instrumental neutron activation analysis (INAA) of the Nuclear Physics Institute at Rez, Czech Republic. Arithmetic and geometric means with their respective standard deviations are presented for 19 elements. Subgroups were formed according to age, gender, and geographic regions from which the samples were collected. Differences in concentrations for the groups and with other childhood populations were explored and discussed.

The US has invested heavily in research, development, and demonstration of efficient and environmentally acceptable technologies for the use of coal. The US has the opportunity to use its leadership position to market a range of advanced coal-based technologies internationally. For example, coal mining output in the Czech Republic has been decreasing. This decrease in demand can be attributed mainly to the changing structure of the Czech economy and to environmental constraints. The continued production of energy from indigenous brown coals is a major concern for the Czech Republic. The strong desire to continue to use this resource is amore » challenge. The Energy and Environmental Research Center undertook two major efforts recently. One effort involved an assessment of opportunities for commercialization of US coal technologies in the Czech Republic. This report is the result of that effort. The technology assessment focused on the utilization of Czech brown coals. These coals are high in ash and sulfur, and the information presented in this report focuses on the utilization of these brown coals in an economically and environmentally friendly manner. Sections 3--5 present options for utilizing the as-mined coal, while Sections 6 and 7 present options for upgrading and generating alternative uses for the lignite. Contents include Czech Republic national energy perspectives; powering; emissions control; advanced power generation systems; assessment of lignite-upgrading technologies; and alternative markets for lignite.« less

2017-09-01

Soil treatment by binders is a standard technology and leads to optimal utilization of excavated soils in road constructions. Soil treatment is controlled in the Czech Republic by EN 14227-15 and Technical Requirement TP 94. Soil treatment using fly ash has not been performed in the Czech Republic, although there is a sufficient normative base. Fly ash produced by burning of hard coal in the Moravian region was tested as a potential binder. Fly ash samples were mixed with loess loams (CI). Tested siliceous fly ash of class F (ASTM C618) did not showed hydraulic properties but it showed positive effect on reducing maximum dry density of mixtures, increasing the IBI value (Immediate bearing index) and decreasing tendency to volume changes when the amount of fly ash was increased. The results of laboratory tests demonstrate the possibility of using fly ashes as a binder for soil treatment.

Specimens archived in wet collections represent valuable material for scientific research. Here, we show that bat fly (Diptera, Nycteribiidae) samples contain DNA of Pseudogymnoascus destructans, a fungus pathogenic to bats. Using dual-probe quantitative PCR, we detected P. destructans DNA on bat flies collected in the Samara, Sverdlovsk and Irkutsk regions of Russia between 2005 and 2017. Fungal load was significantly lower on bat flies from wet collections than on freshly collected mites in the Czech Republic. The bat pathogen was present in the Samara region (European part of Russia) in 2005, that is, a year before recognition of white-nose syndrome in North America. As Samara and Irkutsk regions were identified as new positive locations of P. destructans, our data expand the known geographic distribution of P. destructans. We conclude that ethanol-stored ectoparasites can be used to identify the presence of pathogens in historic bat populations and understudied geographical regions. © 2017 Blackwell Verlag GmbH.

Abstract A golden jackal (Canis aureus) individual was recorded ~40 km east of Prague in the Czech Republic. It is the first record of a living golden jackal in the country; up to now several individuals have been recorded but all of them were either shot dead or killed by a vehicle. The observed animal was documented by camera traps set up for research of carnivore diversity in different habitats in the study area. It was first photographed on 19 June 2015, and in total there were 57 records made by 12 traps until 24 March 2016 when the animal was still present in the area. Forty-nine of the 57 records were made in a shrubby grassland over an area of ~100 ha, 39% of sightings were during the day and 61% in the night. There were two distinct peaks in the circadian activity of the animal, from 4 to 10 a.m., and from 6 p.m. to midnight. We also review the verified records of the golden jackal in the Czech Republic, some of which were only published in local hunting magazines. However, the observation reported in this paper represents the first evidence of a long-term occurrence in Europe of the same golden jackal individual, that persisted for at least nine months and over winter, northwest of Hungarian-Austrian border where the population has been known to reproduce.

Era of Emperor Francis Joseph I is said to be a golden age for the Czech nation. It can be found in numerous panegyric articles to any jubilee of the emperor's rule. What was formally dictated by respect brought by education and by the system of the Greek and Roman tradition adopted in Austria in Middle Ages, seams to be valid today as most of the contemporary technical and economical progress roots within those days. The Czech cultures namely music and art reached international acknowledgement. Though with difficulties, Czech achieved in education and in science as a full-fledged language. After the year 1848 an average citizen was entitled to such freedom as never before. Technical, economical and cultural progress enabled real ascent of the Czech society and its social differentiation. In sixties, after the Austria-Hungary Alignment, Hapsburg government undertook no serious restrains. Such development was nothing unusual. Similar one underwent after the period of storms all European societies from south to north and form west to east. They brought ideas of the French revolution and years 1848/1849 are therefore called "the spring of European nations". In all countries where revolutionary ideas were represented and various countermeasures were accepted, governments were forced to accept temporary arrangements (in Austrian monarchy it was the promise of constitution, language compromise etc.). Nevertheless, in the second half of the 19th century the most important condition for further revival was the long period of peace and stability of international relations. The internal stability of the Austrian monarchy was achieved for long time by the Austria-Hungary Alignment in 1867. After the lost battle at Hradec Kralove in summer 1866 it became clear that contemporary centralistic organization of the state, balancing between absolutism and constitutionalism is not further tenable. Years long pressure of patriotic forces in the parliament brought about division of the Charles-Ferdinand University. Important role in the partition of the Czech Medical Faculty from the German one had the foundation of the Czech Medical Society and the Czech Medical Journal in 1862 patronaged by professors Purkynĕ, Eiselt, Grégr and others. That was the platform for the conception of the Czech medical terminology. Partition of faculties was decided by the law, which was accepted at February 28, 1882. The Czech Medical Faculty was opened only at 1883 because Emperor resolved that professors themselves had to decide to either faculty their clinics would belong. Only professor Eiselt with the First clinic of internal medicine, Weiss with the clinic of surgery and Streng with clinic of obstetrics were assigned to the Czech faculty. Till the official opening on October 15, 1882 all other departments and clinics had to be organized. Though Professor Vilem Weiss as the head of the department and dean of the faculty had his opening Czech lecture already on April 28, 1882, due to material and personal reasons the Czech Medical Faculty was opened only one year later than Faculties of law and philosophy. Most of the eminent members of the Medical faculty remained at the German faculty. However, having higher number of students the Czech faculty became larger and was attended by students from the whole Slavonic world.

Despite widespread vaccination programmes, pertussis remains a significant health burden in many countries. Low awareness of the disease, the high rate of asymptomatic cases in adults and difficulties with diagnosis could explain the under-reporting of pertussis. The lack of data on actual incidence constitutes an obstacle for public health authorities for the implementation of a vaccination strategy against pertussis in adults. The aim of this study was to evaluate the seroprevalence of antibodies against Bordetella pertussis infection in adults and to estimate the actual incidence of the disease compared with the reported incidence. Prospective, multicentre seroprevalence study. The study was conducted in 2000 adult subjects aged ≥18 years who had not received pertussis vaccination within the last 5 years. All enrolled subjects provided a blood sample for serum testing of IgG antibodies against pertussis toxin, performed by enzyme-linked immunosorbent assay, to indicate if they had an acute infection or if they had been infected with pertussis within the last 12 months or earlier. Results were validated in accordance with the guidelines of the European Sero-epidemiology Network 2 and were expressed in ESEN units/ml. A positive concentration of anti-pertussis toxin antibodies, indicating previous pertussis infection, was demonstrated in 39.9% (n = 799) of all study subjects, and 0.40% (n = 8) of subjects had a concentration suggestive of a recent infection (within the last 12 months). The highest antibody seroprevalence was observed in subjects aged 18-29 years (1.46%). No cases of acute infection were detected. During the study period, the reported incidence of pertussis in the adult population was 0.84/100,000 inhabitants. Based on the seroprevalence results from this study, it is estimated that the actual incidence of pertussis could be as much as 699/100,000 inhabitants. The actual incidence of pertussis in adults in the Czech Republic could therefore be at least 200-fold higher than the reported incidence. These findings support the need for pertussis vaccination in the adult population. Copyright © 2017 The Royal Society for Public Health. Published by Elsevier Ltd. All rights reserved.

Inversions are balanced structural chromosome rearrangements, which can influence gene expression and the risk of unbalanced chromosome constitution in offspring. Many examples of inversion polymorphisms exist in human, affecting both heterochromatic regions and euchromatin. We describe a novel, 15 Mb long paracentric inversion, inv(21)(q21.1q22.11), affecting more than a third of human 21q. Despite of its length, the inversion cannot be detected using karyotyping due to similar band patterns on the normal and inverted chromosomes, and is therefore likely to escape attention. Its identification was aided by the repeated observation of the same pair of 150 kb long duplications present in cis on chromosome 21 in three Czech families subjected to microarray analysis. The finding prompted us to hypothesise that this co-occurrence of two remote duplications could be associated with an inversion of the intervening segment, and this speculation turned out to be right. The inversion was confirmed in a series of FISH experiments which also showed that the second copy of each of the duplications was always located at the opposite end of the inversion. The presence of the same pair of duplications in additional individuals reported in public databases indicates that the inversion may also be present in other populations. Three out of the total of about 4000 chromosomes 21 examined in our sample carried the duplications and were inverted, corresponding to carrier frequency of about 1/660. Although the breakpoints affect protein-coding genes, the occurrence of the inversion in normal parents and siblings of our patients and the occurrence of the duplications in unaffected controls in databases indicate that this rare variant is rather non-pathogenic. The inverted segment carried an identical shared haplotype in the three families studied. The haplotypes, however, diverged very rapidly in the flanking regions, possibly pointing to an ancient founder event at the origin of the inversion. The identification of inv(21)(q21.1q22.11) supports the notion that paracentric inversions are the most common form of chromosomal variation and that some of them may still remain undetected.

2015-02-01

From 2008 to 2014, stored product mites have been reported from prepackaged dried food on the market in the Czech Republic. The infestation was by Carpoglyphus lactis (L.) in dried fruits and Tyrophagus putrescentiae (Schrank) in dog feed. The infestation is presumably caused by poor protection of the packages. We compared various packaging methods for their resistance to mites using dried apricots and dog feed in laboratory experiments. The trial packages included nine different plastic films, monofilm, duplex and triplex, and one type of plastic cup (ten replicates per packaging type). All packaging materials are available on the Czech market for dried food products. The samples of dried food were professionally packed in a factory and packaged dried apricots were exposed to C. lactis and dog food to T. putrescentiae. After 3 months of exposure, the infestation and mite density of the prepackaged food was assessed. Mites were found to infest six types of packages. Of the packaging types with mites, 1-5 samples were infested and the maximum abundance was 1,900 mites g(-1) of dried food. Mites entered the prepackaged food by faulty sealing. Inadequate sealing is suggested to be the major cause of the emerged infestation of dried food.

Human dirofilariasis is a zoonotic infection that continues to spread to previously unaffected areas of Europe. In the South Moravian Region of the Czech Republic (CR), imported as well as autochthonous canine infections were recorded in the last decade, and parasite DNA was detected in mosquitoes of Aedes vexans. In the present paper, human Dirofilaria infections are reported from the country for the first time. The samples from five patients with suspected tissue helminthiases were investigated. In particular cases, nematodes were isolated from various tissues including skin of lower leg, soft tissues of finger, subcutaneous tissue of hypogastrium, lymph node and peritoneum. The diagnosis was based on light microscopic morphology and/or DNA analysis of the worms. In addition, ELISA examination of patients' sera for anti-filaria IgG antibodies was performed. In the CR, five cases of human dirofilariasis caused by Dirofilaria repens were recorded during 2010-2014 (species determination for three of them was confirmed besides morphological also by DNA analysis). At least, three of the cases were of autochthonous origin (the patients are Czech citizens residing in South Moravian Region who have never travelled abroad). The findings confirm the natural setting of D. repens in South Moravian Region of the CR. Dirofilariasis should be therefore considered as endemic in this area where it may represent a significant risk factor for public health.

Gene SLCO1B1, encoding solute organic anionic transport polypeptide OATP1B1, belongs to the group of candidates potentially influencing statin treatment safety. OATP1B1 regulates (not only) the hepatic uptake of statins. Its genetic variation was described as an important predictor of statin-associated myopathy in a cohort of patients treated with a maximum dose of simvastatin. However, the impact of SLCO1B1 gene polymorphism on this risk in patients treated with other statins or lower doses of simvastatin needs to be assessed. Therefore, we performed the present study. SLCO1B1 tagging rs4363657 polymorphism was analyzed in 2 groups of patients with dyslipidemia (treated with simvastatin or atorvastatin, 10 or 20 mg per day), subgroup with statin-induced myalgia (N=286), and subgroup (N=707) without myalgia/myopathy, and in 2301 population controls without lipid-lowering treatment. Frequency of the individual genotypes in patients with myalgia/myopathy (TT=62.3%, CT=34.5%, CC=2.8%) did not significantly differ (both P values over 0.19) from that in patients without muscle symptoms (TT=61.4%, CT=32.9%, CC=5.7%) or from the population controls (TT=63.9%, CT=32.5%, CC=3.6%). Null results were also obtained for the dominant and recessive models of the analysis. In Czech patients treated with low statin doses, there is no association between SLCO1B1 gene polymorphism and risk of myalgia/myopathy.

The study examines effects of hot spells on cardiovascular disease (CVD) morbidity and mortality in the population of the Czech Republic, with emphasis on differences between ischaemic heart disease (IHD) and cerebrovascular disease (CD) and between morbidity and mortality. Daily data on CVD morbidity (hospital admissions) and mortality over 1994-2009 were obtained from national hospitalization and mortality registers and standardized to account for long-term changes as well as seasonal and weekly cycles. Hot spells were defined as periods of at least two consecutive days with average daily air temperature anomalies above the 95 % quantile during June to August. Relative deviations of mortality and morbidity from the baseline were evaluated. Hot spells were associated with excess mortality for all examined cardiovascular causes (CVD, IHD and CD). The increases were more pronounced for CD than IHD mortality in most population groups, mainly in males. In the younger population (0-64 years), however, significant excess mortality was observed for IHD while there was no excess mortality for CD. A short-term displacement effect was found to be much larger for mortality due to CD than IHD. Excess CVD mortality was not accompanied by increases in hospital admissions and below-expected-levels of morbidity prevailed during hot spells, particularly for IHD in the elderly. This suggests that out-of-hospital deaths represent a major part of excess CVD mortality during heat and that for in-hospital excess deaths CVD is a masked comorbid condition rather than the primary diagnosis responsible for hospitalization.

Socioeconomic differences in health are a major challenge for public health. However, realistic estimates to what extent they are modifiable are scarce. This problem can be met through the systematic application of the population attributable fraction (PAF) to socioeconomic health inequalities. The authors used cause-specific mortality data by educational level from Belgium, Norway and Czech Republic and data on the prevalence of smoking, alcohol, lack of physical activity and high body mass index from national health surveys. Information on the impact of these risk factors on mortality comes from the epidemiological literature. The authors calculated PAFs to quantify the impact on socioeconomic health inequalities of a social redistribution of risk factors. The authors developed an Excel tool covering a wide range of possible scenarios and the authors compare the results of the PAF approach with a conventional regression. In a scenario where the whole population gets the risk factor prevalence currently seen among the highly educated inequalities in mortality can be reduced substantially. According to the illustrative results, the reduction of inequality for all risk factors combined varies between 26% among Czech men and 94% among Norwegian men. Smoking has the highest impact for both genders, and physical activity has more impact among women. After discussing the underlying assumptions of the PAF, the authors concluded that the approach is promising for estimating the extent to which health inequalities can be potentially reduced by interventions on specific risk factors. This reduction is likely to differ substantially between countries, risk factors and genders.

Phthalates and their metabolites are classified as endocrine modulators. They affect the hormonal balance in both children and adults. The aim of this publication was to compare the urinary levels of phthalate metabolites in selected populations of the Czech Republic (CZ), Slovakia (SK), and Hungary (HU) in relation to the sources of phthalate exposure identified by means of questionnaire (personal care products, floor and wall coverings, plastic toys, and some kinds of foods). Data were obtained through the twin projects COPHES (COnsortium to Perform Human biomonitoring on a European Scale) and DEMOCOPHES (DEMOnstration of a study to COordinate and Perform Human biomonitoring on a European Scale) from 2009 to 2012. The target groups were children aged 6-11 years old and their mothers up to 45 years of age. The metabolites of phthalates (monomethyl phthalate (MMP), monoethyl phthalate (MEP), monobenzyl phthalate (MBzP), mono-cyclohexyl phthalate (MCHP), mono-(2-ethylhexyl) phthalate (MEHP), mono-(2-ethyl-5-hydroxyhexyl) phthalate (5OH-MEHP), and mono-(2-ethyl-5-oxohexyl) phthalate (5OXO-MEHP)) were analysed in first morning urine samples. After enzymatic glucuronide cleavage, the urine sample analyses were performed using ultra-high-performance liquid chromatography-electrospray ionization tandem mass spectrometry (UHPLC-ESI-MS/MS) in one laboratory that qualified in the External Quality Assessment exercises organised by COPHES. Significant differences in phthalate exposure between countries were revealed for children only but not for mothers. The concentrations of 5-OH-MEHP (P<0.001), 5OXO-MEHP (P<0.001), and their sum (P<0.001) were the highest in SK compared to CZ and HU. The health based guidance values for the sum of DEHP metabolites 5-OH MEHP and 5OXO-MEHP established by the German Commission for biomonitoring of 300 µg/L and 500 µg/L for women adults and children, respectively, were only exceeded in one mother and three boys. A significant difference was also found for MEP (P=0.0149), with the highest concentrations detected in HU. In all countries, the increasing frequency of using personal care products significantly elevated the concentrations of MEP. Some differences were observed between countries in the concentrations of individual urinary phthalate metabolites in children. However, the questionnaire results give no direct explanation for the differences between the countries except the variation in using personal care products. Copyright © 2014 Elsevier Inc.

Personalised, predictive and preventive medication process in hospitals—still rather missing: professional opinion survey on medication safety in Czech hospitals (based on professional opinions of recognised Czech health care experts)

PubMed Central

2014-01-01

The survey had the following aims: (1) to rationalise the hypothesis that risks and losses relating to medication process' errors in Czech hospitals are at least comparable with the other developed countries and EU countries especially, (2) to get a valid professional opinion/estimate on the rate of adverse drug events happening in Czech hospitals, (3) to point out that medication errors represent real and serious risks and (4) to induce the hospital management readiness to execute fundamental changes and improvements to medication processes. We read through a lot of studies inquiring into hospitals' medication safety. Then, we selected the studies which brought reliable findings and formulated credible conclusions. Finally, we addressed reputable Czech experts in health care and asked them structured questions whether the studies' findings and conclusions corresponded with our respondents' own experience in the Czech hospital clinical practice and what their own estimates of adverse drug events' consequences were like. Based on the reputable Czech health care expert opinions/estimates, the rate of a false drug administration may exceed 5%, and over 7% of those cause serious health complications to Czech hospital inpatients. Measured by an average length of stay (ALOS), the Czech inpatients, harmed by a false drug administration, stay in hospital for more than 2.6 days longer than necessary. Any positive changes to a currently used, traditional, ways of drug dispensing and administration, along with computerisation, automation, electronic traceability, validation, or verification, must well pay off. Referring to the above results, it seems to be wise to follow the EU priorities in health and health care improvements. Thus, a right usage of the financial means provided by the EC—in terms of its new health programmes for the period 2014–2020 (e.g. Horizon 2020)—has a good chance of a good result in doing the right things right, at the right time and in the right way. All citizens of the EU may benefit using the best practice. PMID:24834138

Extensive fragmentation of the X chromosome in the bed bug Cimex lectularius Linnaeus, 1758 (Heteroptera, Cimicidae): a survey across Europe

Abstract Variation in the number of chromosomes was revealed in 61 samples of Cimex lectularius Linnaeus, 1758 from the Czech Republic and other European countries, hosted on Myotis Kaup, 1829 (4) and Homo sapiens Linnaeus, 1758 (57). The karyotype of all the specimens of Cimex lectularius analysed contained 26 autosomes and a varying number of the sex chromosomes. The number of sex chromosomes showed extensive variation, and up to 20 fragments were recorded. Altogether, 12 distinct karyotypes were distinguished. The male karyotypes consisted of 29, 30, 31, 32, 33, 34, 35, 36, 37, 40, 42 and 47 chromosomes. The females usually exhibited the number of chromosomes which was complementary to the number established in the males from the same sample. However, 11 polymorphic samples were revealed in which the karyotypes of females and males were not complementary each other. The complement with 2n = 26+X1X2Y was found in 44% of the specimens and 57,4% samples of bed bugs studied. The karyotypes with higher chromosome numbers as well as individuals with chromosomal mosaics were usually found within the samples exhibiting particularly extensive variation between individuals, and such complements were not found within samples contaning a few or single specimen. The occurrence of chromosomal mosaics with the karyotype constitution varying between cells of single individual was observed in five specimens (4.3%) from five samples. We assume that polymorphism caused by fragmentation of the X chromosome may result in meiotic problems and non-disjunction can produce unbalanced gametes and result in lowered fitness of individuals carrying higher numbers of the X chromosome fragments. This effect should be apparently enhanced with the increasing number of the fragments and this may be the reason for the observed distribution pattern of individual karyotypes in the studied samples and the rarity of individuals with extremely high chromosome numbers. The assumed lowering of the fitness of individuals carrying higher numbers of the X chromosome fragments could affect population dynamics of variable populations. PMID:24455100

Currently, the cross-border healthcare still represents a marginal part of the Czech healthcare system's performance, though. Compared to the total healthcare expenditures in the Czech Republic that accounted for CZK 299.9 billion in 2014, the costs of the treatment provided to Czech patients abroad constitute mere 0.27%, and the (subsequently refunded) costs of the treatment provided to foreign patients in the Czech Republic 0.24%.Although data on changes in the volume and reimbursements of healthcare due to the Directive 2011/24/EU have not been published yet, we can expect rather evolutionary than revolutionary development of cross-border healthcare volumes. Taking into account all available data, we can conclude that the cross-border healthcare, as specified by the directive currently in force, is important in our conditions above all in relation to our neighbours, i. e. Germany, Austria, Slovakia and Poland.Key words: cross-border healthcare, patient mobility, international reimbursements EU health policy, Directive 2011/24/EU.

Several scientific studies estimate the burden of physical inactivity in different countries, yet in the Czech Republic, this kind of research is still missing. This paper represents one of the first attempts to quantify the costs of physical inactivity in the Czech Republic for 2008. The analysis, based on scientific literature review, uses the comparative risk assessment methodology and applies it on data available in the Czech Republic. In 2008, the financial cost of physical inactivity to public health insurance companies was almost 700 million Kc, or 0.4%, of total healthcare costs. Furthermore, physical inactivity caused 2442, or 2.3%, of all deaths in 2008 and 18,065, or 1.2%, of all disability-adjusted life years in 2004. The costs of physical inactivity in the Czech Republic are considerable, yet slightly smaller than in other comparable studies. The obtained results could be used as an argument for policymakers when conceiving public or private health policy.

Coronary heart disease (CHD) mortality has declined substantially in the Czech Republic over the last two decades. The purpose of this study was to determine what proportion of this CHD mortality decline could be associated with temporal trends in major CHD risk factors and what proportion with advances in medical and surgical treatments. The validated IMPACT mortality model was used to combine and analyse data on uptake and effectiveness of CHD management and risk factor trends in the Czech Republic in adults aged 25-74 years between 1985 and 2007. The main sources were official statistics, national quality of care registries, published trials and meta-analyses, and the Czech MONICA and Czech post-MONICA studies. Between 1985 and 2007, age-adjusted CHD mortality rates in the Czech Republic decreased by 66.2% in men and 65.4% in women in the age group 25-74 years, representing 12,080 fewer CHD deaths in 2007. Changes in CHD risk factors explained approximately 52% of the total mortality decrease, and improvements in medical treatments approximately 43%. Increases in body mass index and in diabetes prevalence had a negative impact, increasing CHD mortality by approximately 1% and 5%, respectively. More than half of the very substantial fall in CHD mortality in the Czech Republic between 1985 and 2007 was attributable to reduction in major cardiovascular risk factors. Improvement in treatments accounted for approximately 43% of the total mortality decrease. These findings emphasize the value of primary prevention and evidence-based medical treatment. © The European Society of Cardiology 2012.

The article draws primarily from the behavioral findings (mainly psychiatric and psychological observations) and points out the important relationships between attention-deficit/hyperactivity disorder (ADHD) symptoms and time orientation. Specifically, the authors argue that there is a significant overlap between the symptoms of ADHD and Present Hedonism. Present Hedonism is defined by Zimbardo's time perspective theory and assessed by Zimbardo Time Perspective Inventory. Developmental data on Present Hedonism of males and females in the Czech population sample (N=2201) are also presented. The hypothesis of relationship between ADHD and Present Hedonism is mainly derived from the prevalence of addictive behavior (mainly excessive Internet use, alcohol abuse, craving for sweets, fatty foods, and fast foods), deficits in social learning, and increased aggressiveness both in ADHD and in the population scoring high on Present Hedonism in the Zimbardo Time Perspective Inventory. We conclude that Zimbardo's time perspective offers both: 1) a potential diagnostic tool - the Zimbardo Time Perspective Inventory, particularly its Present Hedonism scale, and 2) a promising preventive and/or therapeutic approach by the Time Perspective Therapy. Time Perspective Therapy has so far been used mainly to treat past negative trauma (most notably, posttraumatic stress disorder); however, it also has value as a potential therapeutic tool for possible behavioral compensation of ADHD.

The objectives were to: (i) estimate the extent of the injecting equipment (IE) provided by needle exchange programs (NEPs) to injecting drug users (IDUs) in the Czech Republic in 2010; (ii) subsequently validate the recent methodology used for data collection by the Czech National Monitoring Centre for Drugs and Drug Addiction (CMC), and (iii) estimate the number of syringes provided to Czech IDUs. A simple document analysis was performed in order to collect data on the production, sale, and consumption of injecting equipment in the Czech Republic in combination with questionnaire screening in the NEPs and 21 brief interviews with key informants. Ten types of IE most commonly used for drug injecting by the Czech drug users were identified. Approximately 5,038,000 pieces of sterile IE were marketed in the Czech Republic in 2010. According to four manufacturers (with a market share of 96%) and with reference to the year 2010, 5,430,694 pieces of sterile IE were provided to Czech injecting drug users (487,694 pieces of IE were sold to IDUs in pharmacies and 5,038,000 pieces of IE were distributed by NEPs in 2010). We compared the amount of IE provided to IDUs as reported to the CMC National registry by NEPs (4,943,000) with that of IE distributed by manufacturers and distributors (5,038,000) in the country in 2010 and found a difference of less than two percent using two different methodologies. This study confirms the accuracy of the data on the amount of IE exchanged as collected by the CMC monitoring system. This study opens up important public health practice and policy-making issues. The methodology of this study may be used in regions where no data collection system is present or where confirmation of the data related to IE is needed.

This article discusses methods of examining subjective social status (SSS), which is based on the concept of social determinants of health described by Wilkinson and Marmot in 1998. SSS research was conducted with Cooperation from the Scientific and Technical Research (COST) program, with financial support from the Czech Ministry of Education, Youth and Sports. This study is part of a project entitled the "Health and Social Status of Immigrants and Asylum Seekers in the Czech Republic" (registration number OC 10031), which was started in 2010 and concluded in May 2011. The study included 246 respondents of which: 69 (28.1%) had emigrated from Vietnam; 93 (37.8%) from the Ukraine; and 84 (34.1%) from Mongolia. In terms of qualitative strategies, 13 individual immigrants and asylum seekers were personally interviewed. This research was thus conceived as being both quantitative-qualitative, which included the use of the appropriate technical tools (i.e., questionnaires and interviews with select immigrants and asylum seekers). SSS was determined using the Pearson's chi-square test, as well as through correspondence and cluster analyzes. Sign schemes were used to detect select significant relationships in contingency tables. The minimum significance level chosen was α ≤ 0.05. When examining the SSS of select nationalities, differences were observed in the perception of subjective social status. The correspondence analysis results clearly show that Ukrainians best perceived their social status (within the selected parameters). One measure of subjectively perceived social status related to Czech language proficiency (i.e., one criterion was the comprehension of spoken Czech; e.g., whether the respondent could read or speak Czech, or how they assessed their own Czech proficiency). The SSS study clearly revealed typical links among select nationalities living in the Czech Republic, and highlighted risks related to the degree of integration (and its relationship to social exclusion). This study served as a pilot project for follow-up research conducted by the second COST project entitled: "Social Determinants of Health and their Impact on the Health of Immigrants Living in the Czech Republic" (registration number LD 13044 COST). The follow-up study included 1 000 respondents of Slovak, Vietnamese, Ukrainian, Russian and Polish nationality and is currently underway at the Faculty of Health and Social Studies at the University of South Bohemia in the Czech Republic. The methodological tools used were taken from the COST pilot project (which is the topic of this article) and were adjusted as needed (i.e., both objective and subjective criteria were used for examining social status).

Fusarium toxins, Alternaria toxins, and ergot alkaloids represent common groups of mycotoxins that can be found in cereals grown under temperate climatic conditions. Because most of them are chemically and thermally stable, these toxic fungal secondary metabolites might be transferred from grains into the final products. To get information on the commensurate contamination of various cereal-based products collected from the Czech retail market in 2010, the occurrence of "traditional" mycotoxins such as groups of A and B trichothecenes and zearalenone, less routinely determined Alternaria toxins (alternariol, alternariol monomethyl ether and altenuene), ergot alkaloids (ergosine, ergocryptine, ergocristine, and ergocornine) and "emerging" mycotoxins (enniatins A, A1, B, and B1 and beauvericin) were monitored. In a total 116 samples derived from white flour and mixed flour, breakfast cereals, snacks, and flour, only trichothecenes A and B and enniatins were found. Deoxynivalenol was detected in 75% of samples with concentrations ranging from 13 to 594 μg/kg, but its masked form, deoxynivalenol-3-β-d-glucoside, has an even higher incidence of 80% of samples, and concentrations ranging between 5 and 72 μg/kg were detected. Nivalenol was found only in three samples at levels of 30 μg/kg. For enniatins, all of the samples investigated were contaminated with at least one of four target enniatins. Enniatin A was detected in 97% of samples (concentration range of 20-2532 μg/kg) followed by enniatin B with an incidence in 91% of the samples (concentration range of 13-941 μg/kg) and enniatin B1 with an incidence of 80% in the samples tested (concentration range of 8-785 μg/kg). Enniatin A1 was found only in 44% of samples at levels ranging between 8 and 851 μg/kg.

Routine vaccination is one of the most important preventive methods which is responsible for the decreasing trend of morbidity and mortality of vaccine preventable infectious diseases, their complications and sequelae. The impact of vaccination on declining trend of these diseases is well known and confirmed by a large number of epidemiological studies. In the Czech Republic, there is high vaccination coverage in regards to most vaccine preventable diseases. However, during the last decade proportion of parents refusing routine vaccination of their children due to different factors is increasing. The presented study evaluates current situation in the Czech Republic and describes the most significant factors in parents decision making. The study was conducted between 1 July 2013 and 31 March 2014 as a questionnaire based survey (cross-sectional study). The questionnaire was created with multiple choice answers. Questions were addressed to parents or legal representatives of children aged 0-18 years. Types of questions were divided into several subgroups. The study was performed in the Czech Republic in two different districts of Prague and Zlín. In the sample size (n=480) we detected 11 parents who refused vaccination of 11 children (2.29%). The most often refused vaccines in the prevalence study were hexavaccine (1st dose) and measles, mumps and rubella vaccine (1st dose). The hexavaccine includes tetanic anatoxin, diphtheric anatoxin, acellular pertussis vaccine, conjugate vaccine against Haemophilus influenzae b, inactivated polio vaccine, and recombinant vaccine against viral hepatitis B. The measles, mumps, rubella vaccine contains live attenuated viruses of measles, mumps, rubella. We observed increasing trend of routine vaccination refusal in children during the last ten years (compared to situation in the year 2004, p<0.001). The most important factors associated with this progression were distrust to vaccination, fear of some vaccine components and fear of adverse reactions.

In many European countries, foreigners constitute the majority of certain groups of prostitutes, e.g., approximately 90% of the window prostitutes in the red light district of Amsterdam are not native to the Netherlands. The same is true for prostitutes working in bars in Vienna. In cities where registered prostitution is legal, unregistered prostitutes, most of whom are foreigners, often outnumber the registered ones. Central European countries often receive "sex workers" from eastern Europe, e.g., from Bulgaria, the Czech Republic, Slovakia, Hungary, and Romania, whereas the majority of migratory prostitutes in Great Britain and continental western Europe come from Africa, the Caribbean, and South America. In northern Europe, women from Russia, the Czech Republic, Slovakia, Poland, and the Baltic states are prostituting themselves in increasing numbers. Scandinavia has so far been affected relatively less by this mobility. In Spain, France, and Italy, women from Arabic and subSaharan countries are common among prostitutes. Foreign prostitutes move into Turkey along two main routes: women from the Balkan countries come to the western part of the country, whereas those from the former Soviet Union cross the border from Georgia, where they usually operate at resorts along the eastern Black Sea coast. Prostitutes are also mobile within the former communist bloc. For instance, women from Russia prostitute themselves in Lithuania, the Czech Republic, Slovakia, and Hungary. the customers are locals, particularly those with "hard currency", such as businessmen and "sex tourists" from the West. Following the outbreak of civil war in the former Yugoslavia, women from that country are now more frequently seen among the population of migratory prostitutes in Europe.

The main purpose of the study was to validate the defining characteristics of the nursing diagnosis acute pain in the Czech Republic and Slovakia. This is a descriptive study. The validation process involved was based on Fehring's diagnostic content validity model. Four defining characteristics were classified as major by Slovak nurses and eight defining characteristics were classified as major by Czech nurses. Validation of the nursing diagnosis acute pain in the Czech and Slovak sociocultural context has shown that nurses prioritize characteristics that are behavioral in nature as well as patients' verbal reports of pain. Verbal reports of pain and behavioral indicators are important for arriving at the nursing diagnosis acute pain. © 2014 NANDA International, Inc.

AIM To examine the incidence and trends in pediatric inflammatory bowel diseases (IBDs) over 2000-2015 and project the incidence to 2018. METHODS A 16-year prospective study of IBD patients < 19 years of age was conducted in the Czech Republic (the Pilsen region). All incident IBD cases within a well-defined geographical area were retrieved from a prospectively collected computerized clinical database. Historical Czech data were used for comparison (1990-2001). Our catchment population was determined from the census data. We calculated the incidence by relating the number of newly diagnosed cases to the size of the pediatric population-at-risk in each calendar year. Age/sex, disease type, place of residence, and race/ethnicity were identified. RESULTS In total, 170 new IBD cases [105 Crohn’s disease (CD), 48 ulcerative colitis (UC), and 17 IBD-unclassified (IBD-U)] were identified. The median age at IBD diagnosis was 14.2 years, 59.4% were males, and 97.1% were Caucasians. A male preponderance of IBD (P = 0.026) and CD (P = 0.016) was observed. With 109209 person-years in the catchment area, the average incidence of IBD per 100000 person-years was 10.0 (6.2 for CD, 2.8 for UC, and 1.0 for IBD-U) for children aged 0 to 19 years; for those aged 0 to 15 years, the incidence rate was 7.3 (4.6 for CD, 2.0 for UC, and 0.7 for IBD-U). An increase in incidence with age was observed (P = 0.0003). Over the 16-year period, the incidence increased for IBD patients (P = 0.01) and CD in particular (P < 0.0001), whereas the incidence for UC (P = 0.09) and IBD-U (P = 0.339) remained unchanged. IBD-projected data from 2016 to 2018 were 12.1, 12.3 and 12.6 per 100000 person-years, respectively. CONCLUSION Pediatric-onset IBD incidence is around its highest point. The increase, which is particularly pronounced for CD, may be challenging to relate to causes of pediatric disease. PMID:28652662

Process-based erosion modelling is a developing and adequate tool to assess, simulate and understand the complex mechanisms of soil loss due to surface runoff. While the current state of available models includes powerful approaches, a major drawback is given by complex parametrization. A major input parameter for the physically based soil loss and deposition model EROSION 3D is represented by soil texture. However, as the model has been developed in Germany it is dependent on the German soil classification. To exploit data generated during a massive nationwide soil survey campaign taking place in the 1960s across the entire Czech Republic, a transfer from the Czech to the German or at least international (e.g. WRB) system is mandatory. During the survey the internal differentiation of grain sizes was realized in a two fractions approach, separating texture into solely above and below 0.01 mm rather than into clayey, silty and sandy textures. Consequently, the Czech system applies a classification of seven different textures based on the respective percentage of large and small particles, while in Germany 31 groups are essential. The followed approach of matching Czech soil survey data to the German system focusses on semi-logarithmic interpolation of the cumulative soil texture curve additionally on a regression equation based on a recent database of 128 soil pits. Furthermore, for each of the seven Czech texture classes a group of typically suitable classes of the German system was derived. A GIS-based spatial analysis to test approaches of interpolation the soil texture was carried out. First results show promising matches and pave the way to a Czech model application of EROSION 3D.

Verification of the radiometric map of the Czech Republic.

The radiometric map of the Czech Republic is based on uniform regional airborne radiometric total count measurements (1957-1959) which covered 100% of the country. The airborne radiometric instrument was calibrated to a 226 Ra point source. The calibration facility for field gamma-ray spectrometers, established in the Czech Republic in 1975, significantly contributed to the subsequent radiometric data standardization. In the 1990's, the original analogue airborne radiometric data were digitized and using the method of back-calibration (IAEA, 2003) converted to dose rate. The map of terrestrial gamma radiation expressed in dose rate (nGy/h) was published on the scale 1:500,000 in 1995. Terrestrial radiation in the Czech Republic, formed by magmatic, sedimentary and metamorphic rocks of Proterozoic to Quaternary age, ranges mostly from 6 to 245 nGy/h, with a mean of 65.6 ± 19.0 nGy/h. The elevated terrestrial radiation in the Czech Republic, in comparison to the global dose rate average of 54 nGy/h, reflects an enhanced content of natural radioactive elements in the rocks. The 1995 published radiometric map of the Czech Republic was successively studied and verified by additional ground gamma-ray spectrometric measurements and by comparison to radiometric maps of Germany, Poland and Slovakia in border zones. A ground dose rate intercomparison measurement under participation of foreign and domestic professional institutions revealed mutual dose rate deviations about 20 nGy/h and more due to differing technical parameters of applied radiometric instruments. Studies and verification of the radiometric map of the Czech Republic illustrate the magnitude of current deviations in dose rate data. This gained experience can assist in harmonization of dose rate data on the European scale. Copyright © 2016 Elsevier Ltd. All rights reserved.

In the present is in the Czech Republic one methodology how to compute and compare erosion risks. This methodology contain also method to design erosion control measures. The base of this methodology is Universal Soil Loss Equation (USLE) and their result long-term average annual rate of erosion (G). This methodology is used for landscape planners. Data and statistics from database of erosion events in the Czech Republic shows that many troubles and damages are from local episodes of erosion events. An extent of these events and theirs impact are conditional to local precipitation events, current plant phase and soil conditions. These erosion events can do troubles and damages on agriculture land, municipally property and hydro components and even in a location is from point of view long-term average annual rate of erosion in good conditions. Other way how to compute and compare erosion risks is episodes approach. In this paper is presented the compare of various approach to compute erosion risks. The comparison was computed to locality from database of erosion events on agricultural land in the Czech Republic where have been records two erosion events. The study area is a simple agriculture land without any barriers that can have high influence to water flow and soil sediment transport. The computation of erosion risks (for all methodology) was based on laboratory analysis of soil samples which was sampled on study area. Results of the methodology USLE, MUSLE and results from mathematical model Erosion 3D have been compared. Variances of the results in space distribution of the places with highest soil erosion where compared and discussed. Other part presents variances of design control erosion measures where their design was done on based different methodology. The results shows variance of computed erosion risks which was done by different methodology. These variances can start discussion about different approach how compute and evaluate erosion risks in areas with different importance.

Rapid antigen detection enzyme-linked immunosorbent assay (ELISA) testing of cell cultures with organ homogenate from fish, collected from farms with a predominance of common carp or in natural aquaculture in the Czech Republic between 1995 and 2008, identified piscine vesiculovirus in 27 of 178 samples. Using reverse transcription semi-nested PCR, targeting a 550 nucleotide region of the glycoprotein (G) gene, piscine vesiculovirus was confirmed in 23 of the 27 organ samples diagnosed by ELISA as infected. PCR products were amplified and sequenced from 18 isolates from common carp Cyprinus carpio (family Cyprinidae), 2 isolates from northern pike Esox lucius (family Esocidae), and 1 isolate each from Siberian sturgeon Acipenser baerii (family Acipenseridae), common barbel Barbus barbus (family Cyprinidae), and koi carp Cyprinus carpio koi (family Cyprinidae). The sequences (based on 401 nucleotides) clustered into 2 genogroups. The majority of isolates (n = 22), including those from sturgeon and pike, grouped with the spring viraemia of carp virus (SVCV) Genogroup I and Subgroup Id. The 22 isolates could be further subdivided into 2 groups: Id1 (n = 20) and Id2 (n = 2). A marker (a non-conservative nucleotide substitution) for the Id1 SVCV group was identified. It was specifically found in all sequences of Id1 isolates when testing SVCV originating from different countries. The remaining isolate from barbel, was classified in the pike fry-like rhabdovirus Genogroup IV. This is the first confirmation of natural SVCV infection in sturgeon and pike, and pike fry-like rhabdovirus infection in barbel. In the case of the pike fry-like rhabdovirus, this is also its first identification in the Czech Republic. According to the presence/absence of evident clinical signs of rhabdoviral disease in the 3 infected hosts, only the sturgeon seemed to be susceptible to the monitored rhabdovirus.

Organic matter is an essential part of the soil. It affects the physical, chemical, and biological properties of the soil. It is therefore necessary to maintain organic matter in the soil and its quality as the prevention of soil degradation. Loss of organic matter is in the Czech Republic threatened up to 45% of arable soil. The most important reason for the loss of organic matter in the soil is poor management, especially improper crop rotation, cultivation of erosion-prone crops where erosion takes away valuable topsoil with nutrients and organic matter. The aim of our study was to verify the influence of inappropriate management on selected 5 plots in southern Moravia in the Czech Republic. It is the region with the highest incidence of water erosion in the Czech Republic. Were selected plots with significantly sloping, where corn was grown. Samples were taken in the autumn after the harvest, each of topsoil. The sampling sites were placed in positions on the slope where soil was not damaged by erosion, as well as the place greatest damage and the place where washed soil was accumulated. Soil average humus content was for undamaged position on the slope 1.93% and 0.84 quality, the most heavily damaged part of the slope humus content dropped to 1.35% and its quality at only 0.56. In the case of position of accumulated soils was found the average amount of humus 1.70% and 0.90 quality. Humus content and its quality is statistically significantly influenced by water erosion (α = 0.05). The study showed that bad management, when there is not crop rotation adapted to the given conditions and not subjected to any suitable soil-protecting technologies, there is significant damage to soils, which shows mainly organic matter decline and a decline in its quality. Continuation of our study will verify the possibility of stabilization of soil organic matter and draft appropriate technologies.

As part of a diversity evaluation of Sarcocystis in wild carnivores during 2016-2017, samples of diaphragm, tongue and hind-limb muscles were collected from nine districts, examined by compression and characterized molecularly. Cyst walls were thin, with no visible protrusions, and histological sections of infected muscle tissue showed no host responses. Fourteen of 17 badgers (82% prevalence) and one otter (100% prevalence) were positive for sarcocysts. Sequence analyses at four loci (18S rRNA, 28S rRNA, ITS1 and cox1) confirmed the identity as S. lutrae. This is also the first report of a co-infection with muscular sarcocystosis and Trichinella in badger. The finding of Trichinella is important from the zoonotic point of view, since badgers are used for meat consumption. Similar and future monitoring of both parasitic taxa are needed.

Complete characterizations of free and bonded phenolic compounds, presented in four cultivars of barley from two regions of Czech Republic, were achieved, using optimized solvent extraction and liquid chromatography coupled with tandem mass spectrometry. The optimization of extraction of free polyphenols was performed using Box-Behnken design and response surface methodology. The intra-day and extra-day precision of developed method were below 6% and 12%, respectively. The isolation of polyphenols bonded to the cell wall structure was carried out by a hydrolysis process. In all cultivars, p-hydroxybenzoic, p-coumaric and ferulic acids were the most abundant compounds. Their average amounts in barley samples were 17.6, 15.2 and 54.4% (m/m), respectively. The highest amount of these compounds was found in the bonded form, proving the importance of this procedure for the correct characterization of total polyphenols in food matrices.

In 1995 and 1996, the shedding of Toxoplasma gondii oocysts was monitored in the faeces of Felidae in six zoos in the Czech Republic. In all, 2287 samples of faeces from 19 species of Felidae were examined. In Ostrava Zoo, four episodes of shedding of Toxoplasma-like oocysts were identified, using a flotation examination, in a pair of wild cats (Felis silvestris), six episodes in a wild cat held separately, and three episodes in a pair of Amur leopard cats (F. euptilurus). After the passage of sporulated oocysts through laboratory mice, T. gondii was confirmed in the pair of wild cats (three episodes), in the wild cat held separately (three episodes) and in the pair of Amur leopard cats (one episode). In Jihlava Zoo, one episode of shedding of T. gondii oocyst was identified in Geoffroy's cat (Oncifelis geoffroyi) using flotation and isolation examination. The possible sources of toxoplasmosis of the Felidae in zoos are discussed.

Data from 1155 Czech women (493 using oral contraception, 662 non-users), obtained from the Czech National Survey of Sexual Behavior, were used to investigate evolutionary-based hypotheses concerning the predictive value of current oral contraceptive (OC) use on extra-pair and dyadic (in-pair) sexual behavior of coupled women. Specifically, the aim was to determine whether current OC use was associated with lower extra-pair and higher in-pair sexual interest and behavior, because OC use suppresses cyclical shifts in mating psychology that occur in normally cycling women. Zero-inflated Poisson (ZIP) regression and negative binomial models were used to test associations between OC use and these sexual measures, controlling for other relevant predictors (e.g., age, parity, in-pair sexual satisfaction, relationship length). The overall incidence of having had an extra-pair partner or one-night stand in the previous year was not related to current OC use (the majority of the sample had not). However, among the women who had engaged in extra-pair sexual behavior, OC users had fewer one-night stands than non-users, and tended to have fewer partners, than non-users. OC users also had more frequent dyadic intercourse than non-users, potentially indicating higher commitment to their current relationship. These results suggest that suppression of fertility through OC use may alter important aspects of female sexual behavior, with potential implications for relationship functioning and stability.

Good parent-child communication is associated with adolescent well-being. The aim of the present study was to report time trends in parent-adolescent communication in biological and stepfamilies in the Czech Republic between 2002 and 2014 and to assess gender and age differences. The research sample consisted of 16,160 adolescents aged 11, 13, and 15 years (48.1% of boys) who participated in the 2002, 2006, 2010 and 2014 surveys within the Health Behaviour in School-aged Children (HBSC) study in the Czech Republic. The trends in family communication were evaluated using logistic regression. Compared with 2002, a significant increase in the ease of communication with biological parents was observed in 2014. On the other hand, the adolescents' perception of communication with stepparents did not change in this period. Compared with the girls, a higher rate of boys reported communication with their father or stepfather as being easy throughout the study period. The ease of talking to biological parents decreased with age. The growing positive trend demonstrated an improvement in communication in intact families at the beginning of the 21st century, while communication with stepparents remained unchanged from 2002 to 2014. The increase in rates of ease of communication with biological fathers was reported by both genders. However, the ease of talking to biological mothers grew mainly among boys.

2016-01-01

Comprehensive next generation sequencing virus detection was used to detect the whole spectrum of viruses and viroids in selected grapevines from the Czech Republic. The novel NGS approach was based on sequencing libraries of small RNA isolated from grapevine vascular tissues. Eight previously partially-characterized grapevines of diverse varieties were selected and subjected to analysis: Chardonnay, Laurot, Guzal Kara, and rootstock Kober 125AA from the Moravia wine-producing region; plus Müller-Thurgau and Pinot Noir from the Bohemia wine-producing region, both in the Czech Republic. Using next generation sequencing of small RNA, the presence of 8 viruses and 2 viroids were detected in a set of eight grapevines; therefore, confirming the high effectiveness of the technique in plant virology and producing results supporting previous data on multiple infected grapevines in Czech vineyards. Among the pathogens detected, the Grapevine rupestris vein feathering virus and Grapevine yellow speckle viroid 1 were recorded in the Czech Republic for the first time. PMID:27959951

Acoustic Correlates of Focus Marking in Czech and Polish.

Languages vary in the type of contexts that affect prosodic prominence. This paper reports on a production study investigating how different types of foci influence prosody in Polish and Czech noun phrases. The results show that in both languages, focus and givenness are marked prosodically, with pitch and intensity as the main acoustic correlates. Like Germanic languages, Polish and Czech patterns show prosodic focus marking in a broad range of contexts and differ in this regard from other fixed-word-stress languages such as French. This suggests that (a) Polish and Czech are similar to Germanic languages and are unlike Romance languages in marking a variety of types of focus prosodically; (b) there is no close correlation between fixed word stress and lack of prosodic focus marking because Polish, which has fixed stress on the penult, shows prosodic focus marking for all types of focus; and (c) there is no straightforward relationship between flexible word order and whether focus and givenness are prosodically marked, contrary to earlier claims, because both Czech and Polish, with their relatively flexible word order, are more similar to English than Romance languages.

The aim of the study was to examine trends in the prevalence of lifetime cannabis use among the Czech 15-year old students. Data from the nationally representative Health Behaviour in School-aged Children Survey, conducted in the Czech Republic in 2002, 2006, 2010 and 2014, were used. Trends in cannabis use among both boys and girls were modelled through binary logistic regression with period as a predictor of the lifetime cannabis use. The prevalence of lifetime cannabis use has significantly decreased among young Czechs, particularly among boys. Gender differences in cannabis use have been also gradually decreasing since 2002, with no significant differences between genders in recent period. Although there are positive changes in the prevalence of adolescent cannabis use, from the European perspective, Czech students still belong to those with significantly higher rates in this respect. Thus, alongside with the use of other substances, adolescent cannabis consumption remains an important challenge for the national public health policy.

Secular changes in anthropometric parameters reflect the effect of socio-economic conditions in interaction with other factors on individuals in the course of 100-200 years. The main aim of the research was to determine the average body height and weight for the current adult population of men 19 to 94 years old and women 19 to 86 years old in the Czech Republic, and to compare the average values ​​of body height and weight of the monitored group with the reference values ​​for the adult population observed in our country from 1895 to 2001.Body height and weight were measured with standard anthropometry in 973 men aged 19-94 years and 2,606 women aged 19-86 years. The research was carried out from 2013 to 2015. Statistical tests: t-test, one-way analysis of variance (ANOVA). The average body weight and height of the current adult male is 178.58 cm and 80.86 kg, and of adult female 165.99 cm and 65.67 kg. When compared to men, women show significantly lower average height by 12.59 cm and lower weight by 15.19 kg. The results show that men today are about 10.61 cm higher and weigh 9.01 kilograms more than men in 1895. Todays women are about 9.43 centimeters taller, but weigh 0,58 kg less than women of the same age in 1895.Comparison of results from 1895 to 2015 shows that at present there is likely stagnation or decline in the positive secular trend in body height among men and women. The weight of men is increasing while there is stagnation in the body weight of women.

The activity concentration of 137 Cs in samples of coniferous forest humus collected across the territory of the Czech Republic in 1995 and 2005 was analysed, and it was found significantly correlated with the surface deposition caused by the Chernobyl accident. The effective (12.8 y) and environmental (22.3 y) half-lives of radiocaesium in humus were calculated and compared with those in spruce bark. The impact of important forest stand factors, that is, precipitation, content of organic matter, age of trees and pH, on the behaviour of 137 Cs in humus was studied. It was observed that humus samples with a higher proportion of organic matter, higher pH(H2O) and pH(CaCl2) contained higher amounts of 137 Cs. Conversely, with the age of trees, the activity concentration of 137 Cs in humus is decreasing. Higher precipitation and humus acidity decrease the reduction rate of the 137 Cs in humus. These stand factors increase bioavailability of 137 Cs in humus. The transfer and retention of available 137 Cs in biomass of organisms living in humus for a long time can satisfactorily explain the longer residence time of 137 Cs in humus affected by the studied factors.

The aim of this research into 'self-management' was to determine to what extent respondents were aware of their status as overweight or obese. For respondents who indicated that they were overweight or obese, the goal was to determine whether they tried to lose weight, what steps they took to control their, and what specific methods they used. Information was collected using semi-structured interviews from May 31, 2014, to January 30, 2015. Data processing was performed using statistical analysis of the social data SASDM 01/04/10 software. The total study group consisted of 600 respondents, including 302 from the Roma minority, and 298 from the non-Roma majority population (control group). Respondents were selected specifically from South Bohemia Region of the Czech Republic. The sample from the Roma minority was constructed using the snowball method (Snowball Sampling). The control sample of non-Roma was selected through quota sampling. The results indicate that the respondents from both the Roma minority and the non-Roma control group generally recognized when they were overweight or obese, or they were aware of it to a much lesser extent than objective indicators revealed. More than two thirds of the respondents who admitted they were overweight or obese (N = 143) reported that they had suffered from overweight or obesity since they were young adults. Significantly more members of the majority population had tried to lose weight using self-management, whereas the level of effort was significantly less among members of the Roma minority (P = 0). Nevertheless, Roma respondents significantly more often reported (P < 0.01) that they had agreed on a specific weight loss plan with a doctor. The results of our research show that in the context of prevention, it is important to promote self-managed skills, habits and other characteristics that can play an important role in the prevention and treatment of obesity and overweight.

The Czech organised breast cancer screening programme was initiated in 2002. Collection of data on screening mammography examinations, subsequent diagnostic procedures, and final dia-gnosis is an indispensable part of the programme. Data collection is obligatory for all accredited centres, in accordance with regulations issued by the Czech Ministry of Health. This contribution aims to demonstrate the recent results of quality monitoring of the accredited centres. Quality indicators, whose definition complies with international standards, involve the women's participation, the volume of performed examinations, the accuracy of screening mammography, the use of preoperative diagnostics, and the proportion of early detected tumours. Our evaluation documents a continuous improvement in quality of the Czech mammography screening programme, which is thereby in full agreement with international recommendations on quality assurance.

Moss (Pleurozium schreberi), grass (Avenella flexuosa), and 1- and 2-year old spruce (Picea abies) needles were collected over the territory of the Czech Republic at an average sample density of 1 site per 290km(2). The samples were analysed for 39 elements (Ag, Al, As, Ba, Be, Bi, Ca, Cd, Ce, Co, Cr, Cs, Cu, Fe, Ga, Hg, K, La, Li, Mg, Mn, Mo, Na, Nd, Ni, Pb, Pr, Rb, S, Sb, Se, Sn, Sr, Th, Tl, U, V, Y and Zn) using ICP-MS and ICP-AES techniques (the major nutrients Ca, K, Mg and Na were not analysed in moss). Moss showed by far the highest element concentrations for most elements. Exceptions were Ba (spruce), Mn (spruce), Mo (grass), Ni (spruce), Rb (grass) and S (grass). Regional distribution maps and spatial trend analysis were used to study the suitability of the four materials as bioindicators of anthropogenic contamination. The highly industrialised areas in the north-west and the far east of the country and several more local contamination sources were indicated in the distribution maps of one or several sample materials. At the scale of the whole country moss was the best indicator of known contamination sources. However, on a more local scale, it appeared that spruce needles were especially well suited for detection of urban contamination. Copyright © 2010 Elsevier B.V. All rights reserved.

The objective of our study was to provide a genotype analysis of H7N7 and H7N9 influenza A viruses (IAV) and infer their relationships to co-circulating non-H7 IAV genomes. The H7N7 strains were collected in central Europe (Hungary-1, Czech Republic-1, Slovenia-1 and Poland-4) and the H7N9 in the Czech Republic and Spain between 2007 and 2011. Hand in hand with this effort, a novel IAV genotype visualization approach called digital genotyping was developed. This approach relies on phylogenetic data summarization and transformation into a pixel array called a segment identity matrix. The digital genotyping revealed a complicated genetic interplay between the H7 and co-circulating non-H7 IAV genotypes. At the H7 IAV level the most obvious relationships were observed between one Polish H7N7/446/09 and Czech H7N7/11 viruses which, despite the special and temporal distance of 800 km and 15 months, retained at least 6/8 genome segments. Close relationships were also observed between the Czech H7N9, Polish and Slovenian H7N7 on one hand and Hungarian and Slovenian H7N7 isolates on the other. In addition the former genomes exhibited close interplays with the Czech H6N2/09 and H11N9/10-like viruses. The Czech and Spanish H7N9 genomes were completely different and 6/8 of the Czech H7N9-like segments were traced to either the Czech H3N8/07, H11N9/09 and Polish H7N7/09-like viruses. The results of digital genotyping correlated with the previous observations obtained on the Polish H7N7 isolates. As was demonstrated, the digital genotyping provides a well-arranged and easily interpretable output and may serve as an alternative genotyping tool useful for handling and analysing even a large panel of IAV genomes.

Corporate governance in Czech hospitals after the transformation.

2015-08-01

This contribution is a response to the current issue of corporate governance in hospitals in the Czech Republic, which draw a significant portion of funds from public health insurance. This not only has a significant impact on the economic efficiency of hospitals, but ultimately affects the whole system of healthcare provision in the Czech Republic. Therefore, the effectiveness of the corporate governance of hospitals might affect the fiscal stability of the health system and, indirectly, health policy for the whole country. The main objective of this paper is to evaluate the success of the transformation in connection with the performance of corporate governance in hospitals in the Czech Republic. Specifically, there was an examination of the management differences in various types of hospitals, which differed in their ownership structure and legal form. A sample of 100 hospitals was investigated in 2009, i.e., immediately after the transformation had been completed, and then three years later in 2012. With regard to the different public support of individual hospitals, the operating subsidies were removed from the economic results of the corporations in the sample. The adjusted economic results were first of all examined in relationship to the type of hospital (according to owner and legal form), and then in relation to its size, the size of the supervisory board and the education level of the senior hospital manager. A multiple median regression was used for the evaluation. One of the basic findings was the fact that the hospital's legal form had no influence on economic results. Successful management in the form of adjusted economic results is only associated with the private type of facility ownership. From the perspective of our concept of corporate governance other factors were under observation: the size of the hospital, the size of the supervisory board and the medical qualifications of the senior manager had no statistically verifiable influence on the efficiency of the hospital management, though we did record certain developments as a result of the transformation process. The economic results that were reported were significantly distorted by the operating subsidies from the founder. The results can be used immediately on several practical levels: on the macro level as part of the state's formulation of health policy, particularly in the optimization of the structure of healthcare providers, as well as for the completion of reforms in legal forms and hospital founders, and on the micro level as part of the effective administration and governance of hospitals through corporate governance regardless of the form of ownership.

According to the International Statistical Classification of Diseases and Related Health Problems 10th Revision, tobacco dependence is coded by group F17 - Mental and behavioral disorders due to use of tobacco. There are other codes for diagnoses and conditions associated with tobacco use. The aim of our analysis was to determine how often these codes are reported in clinical practice. We observed the incidence of diagnoses F17, P04.2, Z72.0 or T65.2 in years 2002-2011 in hospitalized patients and the F17 diagnosis in patients of psychiatric health facilities. According to data from the Institute of Health Information and Statistics of the Czech Republic diagnoses indicating smoking patients were reported in 1.5% of hospitalized patients in 2011, although the prevalence of smoking in the population is around 30% in last 15 years. Smoking-related diagnoses were reported in 2.1% of cases in Internal medicine departments. Codes F17, T65.2 and Z72.0 occurred as an accessory diagnose in vascular brain disease in 1.8% of hospitalizations and for respiratory tract neoplasms (dg. C32-C34) it was 7.1% of hospitalizations. These results demonstrate the underestimation of the importance of smoking and its relationship to clinical disciplines. Although it is one of the most common diseases in the population with a direct relation to fatal diseases of civilization, the information on its incidence is not used in clinical practice.

Lung Cancer Risk from Occupational and Environmental Radon and Role of Smoking in Two Czech Nested Case-Control Studies

Tomasek, Ladislav

2013-01-01

The aim of the present study was to evaluate the risk of lung cancer from combined exposure to radon and smoking. Methodologically, it is based on case-control studies nested within two Czech cohort studies of nearly 11,000 miners followed-up for mortality in 1952–2010 and nearly 12,000 inhabitants exposed to high levels of radon in homes, with mortality follow-up in 1960–2010. In addition to recorded radon exposure, these studies use information on smoking collected from the subjects or their relatives. A total of 1,029 and 370 cases with smoking information have been observed in the occupational and environmental (residential) studies, respectively. Three or four control subjects have been individually matched to cases according to sex, year of birth, and age. The combined effect from radon and smoking is analyzed in terms of geometric mixture models of which the additive and multiplicative models are special cases. The resulting models are relatively close to the additive interaction (mixing parameter 0.2 and 0.3 in the occupational and residential studies, respectively). The impact of the resulting model in the residential radon study is illustrated by estimates of lifetime risk in hypothetical populations of smokers and non-smokers. In comparison to the multiplicative risk model, the lifetime risk from the best geometric mixture model is considerably higher, particularly in the non-smoking population. PMID:23470882

Experimental data on the cross sections for channels of fusion and transfer reactions induced by beams of radioactive halo nuclei and clustered and stable loosely bound nuclei were analyzed, and the results of this analysis were summarized. The interplay of the excitation of single-particle states in reaction-product nuclei and direct reaction channels was established for transfer reactions. Respective experiments were performed in stable ({sup 6}Li) and radioactive ({sup 6}He) beams of the DRIBs accelerator complex at the Flerov Laboratory of Nuclear Reactions, Joint Institute for Nuclear Research, and in deuteron and {sup 3}He beams of the U-120M cyclotron at themore » Nuclear Physics Institute, Academy Sciences of Czech Republic (Řež and Prague, Czech Republic). Data on subbarrier and near-barrier fusion reactions involving clustered and loosely bound light nuclei ({sup 6}Li and {sup 3}He) can be described quite reliably within simple evaporation models with allowance for different reaction Q-values and couple channels. In reactions involving halo nuclei, their structure manifests itself most strongly in the region of energies below the Coulomb barrier. Neutron transfer occurs with a high probability in the interactions of all loosely bound nuclei with light and heavy stable nuclei at positive Q-values. The cross sections for such reactions and the respective isomeric ratios differ drastically for nucleon stripping and nucleon pickup mechanisms. This is due to the difference in the population probabilities for excited single-particle states.« less

Relationship between atmospheric pollution in the residential area and concentrations of polycyclic aromatic hydrocarbons (PAHs) in human breast milk.

Human milk is an important source of beneficial nutrients and antibodies for newborns and infants and, under certain circumstances, its analysis may provide information on mothers' and infants' exposure to various contaminants. In the presented study, we have introduced the new analytical approach for analysis of 24 highly occurring polycyclic aromatic hydrocarbons (PAHs) in this indicator matrix. The sample preparation procedure is based on an ethyl acetate extraction of milk; the transfer of analytes into an organic layer is enhanced by addition of inorganic salts, i.e. sodium chloride and magnesium sulphate. Following the clean-up of a crude extract on silica SPE columns, gas chromatography coupled to triple quadrupole mass spectrometry is used for PAH identification and quantitation. The average recoveries of targeted PAHs from spiked samples were in the range of 68-110% with repeatabilities below 30% and method quantitation limits ranging from 0.03 to 0.3ng/g lipid weight. This newly validated method was successfully applied for analyses of 324 human milk samples collected from nonsmoking women during two sampling periods (summer and winter) in two residential areas in the Czech Republic differing in atmospheric pollution by PAHs. From 24 targeted analytes 17 were detected at least in one sample. Phenantherene, fluoranthrene, pyrene and fluorene were the most abundant compounds found at average concentration of 13.81, 1.80, 0.86, and 2.01ng/g lipid weight respectively. Comparing the data from two sampling periods, in both areas higher concentrations were measured in samples collected during winter. Also in the highly industrialized locality with heavily contaminated air PAH amounts in milk were higher than in the control locality. These first data on PAH concentrations in human milk collected in the Czech Republic are comparable with measurements for nonsmoking women reported earlier in the United States but significantly lower than results from China, Turkey or Italy.

Transmission of canine leishmaniosis (CanL) is described in three consecutive generations of female Boxers living in a non-endemic environment in the Czech Republic. Infection of the first generation female likely occurred during a breeding visit to Italy and the dog died with typical clinical signs of the disease but without definitive laboratory diagnosis. The second and third generation offsprings never left the Czech Republic, suffered from clinical CanL confirmed by polymerase chain reaction and serology, and were apparently infected by transplacental transmission. Persistence of CanL in the Czech Republic over 7 years with a suspected origin in an endemic region and progression of infection through subsequent generations in a non-endemic country exemplifies that this disease may establish itself also in areas where no obvious vectors are present.

CzechGeo/EPOS is the consortium of seven geoscience institutions in the Czech Republic (Institute of Geophysics AS CR Prague, Institute of Rock Structure and Mechanics AS CR Prague, Institute of Geonics AS CR Ostrava, Institute of Physics of the Earth, Masaryk University Brno, Faculty of Mathematics and Physics, Charles University Prague, Faculty of Science, Charles University Prague, and Research Institute of Geodesy, Cartography and Topography Zdiby). These institutions operate a distributed system of seismic, GPS, magnetic, gravimetric and geodynamic observatories. The operational and personal costs of CzechGeo/EPOS are mostly covered by the Ministry of education, sports and youth within the support of twelve large research infrastructures in the Czech Republic. Web pages of the project www.czechgeo.cz are being built as a data portal which should integrate all the data and services provided by the involved institutions and research infrastructures. Seismic portal offers selected portions of digital data from permanent, local and temporary seismic stations, locations of seismic events in the country and worldwide, daily seismograms from permanent observatories and local seismic network Webnet, seismic bulletins and catalogs, and macroseismic observations on the territory of the Czech Republic. Magnetic portal involves besides real-time magnetograms also recent state of geomagnetic activity and its forecast for the next day. GPS portal will provide preprocessed data from regional GPS stations. Building the national portal is closely related with the development of the Preparatory phase of the EPOS (European Plate Observing System) project.

Isothermal and non-isothermal infiltration experiments were carried out in the laboratory on large undisturbed soil columns (19 cm in diameter, 25 cm high) taken at the experimental catchments Roklan (Sumava Mountains, Czech Republic) and Uhlirska (Jizera Mountains, Czech republic). The aim of the study was twofold. The first goal was to obtain water flow and heat transport data for indirect parameter estimation of thermal and hydraulic properties of soils from two sites by inverse modelling. The second aim was to investigate the extent of impact of the temperature on saturated hydraulic conductivity (Ksat) and dispersity of solute transport. The temperature of infiltrating water in isothermal experiment (20 °C) was equal to the initial temperature of the sample. For non-isothermal experiment water temperature was 5°C, while the initial temperature of the sample was 20°C as in previous case. The experiment was started by flooding the sample surface. Then water level was maintained at constant level throughout the infiltration run using the optical sensor and peristaltic pump. Concentration pulse of deuterium was applied at the top of the soil sample, during the steady state flow. Initial pressure head in the sample was close to field capacity. Two tensiometers and two temperature sensors were inserted in the soil sample in two depths (9 and 15 cm below the top of the sample). Two additional temperature sensors monitored the temperature entering and leaving the samples. Water drained freely through the perforated plate at the bottom of sample by gravity. Inflow and outflow water flux densities, water pressure heads and soil temperatures were monitored continuously during experiments. Effluent was sampled in regular time intervals and samples were analysed for deuterium concentrations by laser spectroscopy to develop breakthrough curves. The outcome of experiments are the series of measured water fluxes, pressure heads and temperatures ready for inverse modelling by dual permeability. The saturated hydraulic conductivity of soil columns was higher in the case of higher temperature of flowing water. The change was however not proportional to Ksat change induced by temperature change of viscosity only.

The Czech Republic is faced with making choices between pharmaceutical products, including depot injectable antipsychotics. A pharmacoeconomic analysis was conducted to determine the cost-effectiveness of atypical depots. An existing 1-year decision-analytic framework was adapted to model drug use in this healthcare system. The average direct costs to the General Insurance Company of the Czech Republic of using paliperidone palmitate (Xeplion®), risperidone (Risperdal Consta®), and olanzapine pamoate (Zypadhera®) were determined. Literature-derived clinical rates populated the model, with costs adjusted to 2012 Euros using the consumer price index. Outcomes included quality-adjusted life-years (QALYs), days in remission, and proportions hospitalized or visiting emergency rooms. One-way sensitivity analyses were calculated for all important inputs. A multivariate probability analysis was used to examine the stability of results using 10,000 iterations of simulated input over reasonable ranges of all included variables. Expected average costs/per patient treated were €5377 for PP-LAI, €6118 for RIS-LAI, and €6537 for OLZ-LAI. Respective QALYs were 0.817, 0.809, and 0.811; ER visits were 0.127, 0.134, and 0.141; hospitalizations were 0.252, 0.298, and 0.289. Results were generally robust in sensitivity analyses. PP-LAI dominated RIS-LAI and OLZ-LAI in 90.2% and 92.1% of simulations, respectively. Results were insensitive to drug prices but sensitive to adherence and hospitalization rates. PP-LAI dominated the other two drugs, as it had a lower overall cost and superior clinical outcomes, making it the preferred choice. Using PP-LAI in place of RIS-LAI for chronic relapsing schizophrenia would reduce the overall costs of care for the healthcare system.

Asteroids@Home

2012-10-01

We present a new project called Asteroids@home (http://asteroidsathome.net/boinc). It is a volunteer-computing project that uses an open-source BOINC (Berkeley Open Infrastructure for Network Computing) software to distribute tasks to volunteers, who provide their computing resources. The project was created at the Astronomical Institute, Charles University in Prague, in cooperation with the Czech National Team. The scientific aim of the project is to solve a time-consuming inverse problem of shape reconstruction of asteroids from sparse-in-time photometry. The time-demanding nature of the problem comes from the fact that with sparse-in-time photometry the rotation period of an asteroid is not apriori known and a huge parameter space must be densely scanned for the best solution. The nature of the problem makes it an ideal task to be solved by distributed computing - the period parameter space can be divided into small bins that can be scanned separately and then joined together to give the globally best solution. In the framework of the the project, we process asteroid photometric data from surveys together with asteroid lightcurves and we derive asteroid shapes and spin states. The algorithm is based on the lightcurve inversion method developed by Kaasalainen et al. (Icarus 153, 37, 2001). The enormous potential of distributed computing will enable us to effectively process also the data from future surveys (Large Synoptic Survey Telescope, Gaia mission, etc.). We also plan to process data of a synthetic asteroid population to reveal biases of the method. In our presentation, we will describe the project, show the first results (new models of asteroids), and discuss the possibilities of its further development. This work has been supported by the grant GACR P209/10/0537 of the Czech Science Foundation and by the Research Program MSM0021620860 of the Ministry of Education of the Czech Republic.

The main aim of the study was to evaluate associations between morphological variability of Trichuris females from sheep and roe deer and their rDNA polymorphism in whipworm populations from the Czech Republic. The results introduced the use of new molecular markers based on the internal transcribed spacer (ITS)1-5.8S RNA-ITS2 region polymorphisms, as useful tools for the unambiguous differentiation of congeners Trichuris ovis and Trichuris discolor. These markers revealed both parasites in roe deer and in sheep; however, T. ovis females predominated in sheep while T. discolor females occurred mostly in roe deer. Additional analysis of ITS1-5.8 rRNA-ITS2 discovered the genetic uniformity of the analysed T. discolor but high haplotype variation of T. ovis. Simultaneously, molecularly designated female individuals of both species were categorised into four morphotypes (MT) on the basis of morphology of genital pore area. MT1 and MT4 (vulvar opening on everted vaginal appendage/on visible cuticular bulge) occurred only in T. ovis, MT2 (uneverted vagina-vulvar opening without any elevation) was identified only in T. discolor and MT3 (transient type of vulvar opening on a small swelling) was observed in both species. Statistical analysis of biometric data confirmed that morphology of vulva is not a reliable marker for the species determination. On the basis of the ITS1-5.8S RNA-ITS2 region variability, we carried out a phylogenetic analysis (maximum likelihood method, Hasegawa-Kishino-Yano model) which showed that T. ovis haplotypes from the Czech Republic and Ireland and T. discolor haplotypes from the Czech Republic, Spain, Iran and Japan are sister OTUs.

The Movement Assessment Battery for Children-second edition (MABC-2) Age Band 1 is widely used to identify preschoolers with motor difficulties. Despite unsatisfactory construct validity of the original three-factor model, MABC-2 (manual dexterity, aiming and catching, and balance), previous research has not considered possible age and gender differences throughout the entire preschool period. The aim of this study was to verify the construct validity of the MABC-2 Age Band 1 in a population of Czech preschoolers with respect to age and gender. Using data from 510 Czech preschoolers (3-6 years; 4.9 ± 1.1 years), confirmatory factor analyses (CFA) were used for each age category and gender. The goodness-of-fit indices of CFA supported the original three-factor model of the MABC-2 only in 3- and 4-year-old children, and in boys (3-6 years). Low factor loadings and ceiling effects of several test items (Drawing Trail, Walking Heels Raised, and Jumping on Mats) seem to be a probable cause of weak fit indices in 5- and 6-year-old children and in girls (3-6 years). These results suggest that the MABC-2 can be a valid tool for assessing motor development and identifying motor difficulties among 3- to 4-year olds, and generally fits better for preschool boys in the Czech Republic. However, in 5- to 6-year olds, ceiling effects and a low power of discrimination was found for the Drawing Trail, Walking Heels Raised, and Jumping on Mats tests. Therefore, the three-factor model is not appropriate for all preschoolers, and separate norms should be established for each age and gender.

To describe adverse event reporting processes in long-term care facilities in the Czech Republic. Prospective cohort study involving a written questionnaire followed by in-person structured interviews with selected respondents. Long-term care facilities located in the Czech Republic. Staff of 111 long-term care facilities (87% of long-term care facilities in the Czech Republic). None. Sixty-three percent of long-term health-care facilities in the Czech Republic have adverse event-reporting processes already established, but these were frequently very immature programs sometimes consisting only of paper recording of incidents. Compared to questionnaire responses, in-person interview responses only partially tended to confirm the results of the written survey. Twenty-one facilities (33%) had at most 1 unconfirmed response, 31 facilities (49%) had 2 or 3 unconfirmed responses and the remaining 11 facilities (17%) had 4 or more unconfirmed responses. In-person interviews suggest that use of a written questionnaire to assess the adverse event-reporting process may have limited validity. Staff of the facilities we studied expressed an understanding of the importance of adverse event reporting and prevention, but interviews also suggested a lack of knowledge necessary for establishing a good institutional reporting system in long-term care.

This paper addresses the course, extent, and impacts of a windstorm that occurred on 20-21 December 1740, in the Czech Lands. The analysis is based on documentary data included in chronicles, "books of memory", memoirs, damage reports, urbaria, and cadastral records, as well as secondary sources. The windstorm started with a thunderstorm in the afternoon of 20 December, continued during the night, and was followed by a flood. It also appeared in documentary data from Bavaria, Thuringia, Saxony, Silesia, Slovakia, and Hungary. The event may be related to a cyclone north-west of the Czech territory moving to the east with an intense western flow over central Europe. The storm did great material damage to houses, farm buildings, churches, and forests and is recorded in various documentary sources for 85 places in the Czech Lands. The windstorm had a significant influence on the development of local plantation forestry (discussed in greater detail). Judging by territorial extent and damage done, this windstorm, compared to other similar events, has been classified as "the windstorm of the eighteenth century" in the Czech Lands. This contribution demonstrates the potential of documentary evidence for the elucidation of heavy windstorms in the pre-instrumental period in Europe.

We describe the first case of chancroid seen in the Czech Republic, diagnosed in a 40-year-old heterosexual HIV-positive man. Despite genital localization of the ulcer, the transmission of Haemophilus ducreyi infection in our patient remains unclear, as he denied having sexual intercourse and he did not travel outside the Czech Republic for several months before the ulcer appeared. The correct diagnosis has been revealed by a multiplex nucleic acid amplification test. Physicians in countries in the eastern and central Europe region should be aware that chancroid can occur in their patients.

The pelvic bones and skull are not always available when human remains are discovered in a forensic setting. This study investigates the suitability to a Scottish sample of existing methods of sexing based on calcification patterns in the costal cartilages. Radiographs of chest plates of 41 cadavers, 22 male and 19 female aged 57-96 years were analyzed for their calcification patterns according to the methods of McCormick et al. (1985, Am. J. Phys. Anthropol. 68:173-195) and Rejtarova et al. (2004, Biomed. Pap. Med. Fac. Univ. Palacky. Olomouc. Czech. Repub. 148:241-243). With the method of Rejtarova et al. (2004, Biomed. Pap. Med. Fac. Univ. Palacky. Olomouc. Czech. Repub. 148:241-243) none of the male specimens was sexed correctly. Of the chest plates that were suitable for sexing, the method of McCormick et al. (1985, Am. J. Phys. Anthropol. 68:173-195) correctly sexed 82.4% of the female specimens but only 41.2% of the males. To improve the reliability, we suggest a new method of sex determination based on whether the calcified deposits in the second to seventh costal cartilages are predominantly trabecular bone or sclerotic calcified deposits. Specimens with minimal amounts or similar amounts of trabecular bone or sclerotic deposits in the costal cartilages are not appropriate for our method. When such specimens (10 specimens) were excluded, our method correctly sexed 16 of 17 (94%) males and 12 of 14 (86%) females. The authors acknowledge that their sample is small and that many of their subjects were elderly and that the method should be tested on a larger sample group before application in a forensic context. © 2014 Wiley Periodicals, Inc.

The main aim of the eGovernment programme in the Czech Republic is to enhance the efficiency of public administration. The Digital Map of Public Administration (DMVS) should be composed of digital orthophotographs of the Czech Republic, digital and digitised cadastral maps, digital purpose cadastral map (ÚKM) and a technical map of municipality, if available. The DMVS project is a part of computerisation of public administration in the Czech Republic. The project enhances the productivity of government administration and also simplifies the processes between citizens and public administration. The DMVS project, that should be compliant with the INSPIRE (Infrastructure for Spatial Information in the European Community) initiative, generates definite demand for geodata on the level of detail of land data model. The user needs that are clearly specified and required are not met due to inconsistencies in terminology, data management and level of detail.

This paper's purpose is to define the immigrant's status and give evidence of psycho-social problems of the uprooted in a survey of hungarian and czech refugees. It is evident that morbidity of immigrant populations is generally increased. Also, certain nosological states are prevalent. Most of all, we have investigated delusions of reference in a culturally alien environment. Moreover, some psychoanalytical and sociological aspects pertaining to the immigrant's status (identity, assimilation, overadaptation, feelings of discrimination, socio-cultural hierarchy) are discussed. Ultimately, practical approaches to the psychological misery of immigrants are suggested.

Aquatic organisms can be affected not only via polluted water but also via their food. In the present study, we examined bioaccumulation of seventy pharmaceuticals in two benthic organisms, Hydropsyche sp. and Erpobdella octoculata in a small stream affected by the effluent from a sewage treatment plant (STP) in Prachatice (South Bohemia region, Czech Republic). Furthermore, water samples from similar locations were analyzed for all seventy pharmaceuticals. In water samples from a control locality situated upstream of the STP, ten of the seventy pharmaceuticals were found with average total concentrations of 200 ng L(-1). In water samples collected at STP-affected sites (downstream the STP's effluent), twenty-nine, twenty-seven and twenty-nine pharmaceuticals were determined at average total concentrations of 2000, 2100 and 1700 ng L(-1), respectively. Six of the seventy pharmaceuticals (azithromycin, citalopram, clarithromycin, clotrimazole, sertraline, and verapamil) were found in Hydropsyche. Four pharmaceuticals (clotrimazole, diclofenac, sertraline, and valsartan) were detected in Erpobdella. Using evaluation criterion bioconcentration factor (BCF) is higher than 2000 we can assign azithromycin and sertraline as bioaccumulative pharmaceuticals. Even pharmaceuticals present at low levels in water were found in benthic organisms at relatively high concentrations (up to 85 ng g(-1) w.w. for azithromycin). Consequently, the uptake of pharmaceuticals via the food web could be an important exposure pathway for the wild fish population. Copyright © 2014. Published by Elsevier Ltd.

A survey of naso-pharyngeal and subcutaneous myiasis affecting roe deer (Capreolus capreolus) was conducted in the Czech Republic over an 8-year period (1999-2006). A total of 503 bucks and 264 does from six hunting localities were examined. The sampling area comprised predominantly agricultural lowlands and a mountain range primarily covered by forest. Since 1997, the deer have been treated each winter across the board with ivermectin (150 mg/kg, CERMIX® pulvis, Biopharm, CZ). Parasites found were the larvae of Hypoderma diana and Cephenemyia stimulator. There were no significant differences in warble fly infection among captured animals in the individual hunting localities. Overall, 146 (28.8%) of 503 animals (bucks) were infected with Cephenemyia stimulator larvae; body size of the second instar larva reached 13-18 mm. The prevalence ranged from 16.1 to 42.9% per year, and the mean intensity from 6 to 11 larvae per animal. Additionally, a total of 264 roe deer (does) were examined for H. diana larvae, and 77 (29.1%) were found to be positive; body size of the second instar larva reached 17 mm. The prevalence ranged from 18.8 to 50.0% per year, and the mean intensity from 13 to 22 larvae per animal. The results showed that the bot flies, Cephenemyia stimulator as well as H. diana, are common parasites in roe deer in the Czech Republic, and that through the help of treatment (ivermectin), it is possible to keep parasite levels low. The body weights of infected and non-infected H. diana deer did not differ significantly.

Ochratoxin A is a nephrotoxic and renal carcinogenic mycotoxin and is a common contaminant of various food commodities. Eighty six kinds of foodstuffs (1032 food samples) were collected in 2011-2013. High-performance liquid chromatography with fluorescence detection was used for ochratoxin A determination. Limit of quantification of the method varied between 0.01-0.2 μg/kg depending on the food matrices. The most exposed population is children aged 4-6 years old. Globally for this group, the maximum ochratoxin A dietary exposure for "average consumer" was estimated at 3.3 ng/kg bw/day (lower bound, considering the analytical values below the limit of quantification as 0) and 3.9 ng/kg bw/day (middle bound, considering the analytical values below the limit of quantification as 1/2 limit of quantification). Important sources of exposure for this latter group include grain-based products, confectionery, meat products and fruit juice. The dietary intake for "high consumers" in the group 4-6 years old was estimated from grains and grain-based products at 19.8 ng/kg bw/day (middle bound), from tea at 12.0 ng/kg bw/day (middle bound) and from confectionery at 6.5 ng/kg bw/day (middle bound). For men aged 18-59 years old beer was the main contributor with an intake of 2.60 ng/kg bw/day ("high consumers", middle bound). Tea and grain-based products were identified to be the main contributors for dietary exposure in women aged 18-59 years old. Coffee and wine were identified as a higher contributor of the OTA intake in the population group of women aged 18-59 years old compared to the other population groups.

The STD problem emerged in the Czech Republic as a result of geopolitical and social and economic changes in the state. Prostitution is concentrated mainly around border areas with Austria and Germany, contributing to the increase in STDs. The Czech-German project "Jana," based on a project umbrella network of the WHO, was organised. To prevent STDs, including HIV/AIDS, and assessment of STD prevalence in the target group. Prostitutes working in night clubs and in the streets and roads of three districts in the West Bohemian Region of the Czech Republic bordering on Germany were studied. Interactions included street work, venereology check up, psychology and sociology counselling, psychological preparation on possible treatment, and continuous and regular contact. The number of "love clubs" involved in project "Jana" increased from 46 in 1997 to 72 in 2000. Of 561 street girls registered in the project during 1997-2001, there was one HIV positive, every 11th prostitute had syphilis, and one in 93 women had gonorrhoea, whereas incidence of syphilis in the Czech Republic was 10.2/100000 and that of gonorrhoea 9.5/100000 inhabitants in 2001, 31 women had Chlamydia trachomatis urinary tract and genital infection, and 25 were HBsAg positives. STD frequency revealed in project participants significantly exceeds numbers of STDs in the other inhabitants of the Czech Republic. The majority of prostitutes were foreigners, mostly Ukrainians and Russians. The situation in the border areas is alarming. The priority must be to concentrate efforts on prevention of spread of venereal diseases in borders of economically disparate states.

This paper analyses temporal and spatial variability of April-September (the vegetation period) droughts in the Czech Lands over the last 500 years. The study is based on different types of documentary data (e.g. chronicles, newspapers, economic sources, weather diaries) covering the pre-instrumental period AD 1501-1804 and on the systematic instrumental meteorological measurements afterwards. Historical-climatological database of the Czech Lands is used for the study of the duration and intensity of drought episodes based on the series of precipitation indices created from documentary data in a 7-degree scale from -3 (extremely dry) to +3 (extremely wet). For the instrumental period of 1805-2012 Palmer's Z-index and PDSI series for mean Czech temperature and precipitation series are used (they were calculated from homogeneous series of 10 and 14 stations respectively). Consequently the 500-year chronology of drought episodes derived from documentary and instrumental data is compiled and the temporal (frequency, seasonality and intensity) and spatial variability of droughts in the Czech Lands from AD 1501 is analysed. The most outstanding drought events are selected and analysed in detail also with respect to their human impacts. The results obtained for the Czech Lands are compared with drought episodes known in Central Europe from other studies and are evaluated with respect to climate variability in Central Europe during the last 500 years (this research is supported by projects InterDrought no. CZ.1.07/2.3.00/20.0248, and GA CR no. P209/11/0956).

The role of coal in the economy of the Czech Republic

The Czech Republic ranks among the countries with high total reserves of hard coal and lignite. Therefore coal always had and still has a significant role in covering the power demand of the Czech Republic. Transition of the national economy, based on the principles of the market economy and private ownership, affects among others also behavior of the mining companies. A strong emphasis is also aimed at the environmental aspects concerning both the process of coal mining and the process of its utilization. Within these intentions the power policy of the Czech Republic is formulated. The Czech Republic, which hasmore » 10 mil. inhabitants, ranks among the countries with a high share of industry in the process of creating the gross national product. This state has its historical roots as on the present territory of the Czech Republic there had been concentrated a majority of industrial and mining capacities of the Hapsburg Empire. The First World War resulted among others in the decline of the Hapsburg Empire. Within this process Czechoslovak Republic was established (apart from other things the center of democracy in the Central Europe). In that republic the industry had an important position. The industrial potential had been expanded even during the occupation of Czechoslovakia by Nazi Germany in the years 1939 - 1945. After the Second World War when Europe was divided into two political spheres Czechoslovakia became a significant industrial base of so called East Bloc. Such a development and the needs of the Eastern Bloc resulted in the intensive development of the heavy industry on the territory of Czechoslovakia.« less

Droughts are, together with floods, the most important natural extremes in the Czech Republic. In the last c. 20 years even some irregular alternations of years with severe droughts on the one hand (2000, 2003, 2007, 2011-2012, 2014-2015) and severe floods on the other (1997, 1998, 2002, 2005, 2009, 2010, 2013), reflecting greater variability of the water cycle, can be observed. Great attention devoted to the study of past, present and future of droughts in the Czech Republic in a few last years allowed to obtain basic knowledge related to long-term spatial-temporal variability of droughts, combining dendrochronological, documentary and instrumental data, synoptic causes and climate forcings of droughts, case studies of important drought anomalies with significant social-economic consequences (like drought of 1947), impacts of droughts in agriculture, forestry or water management, and future droughts according to model estimates. Basic results obtained are summarised and documented by several typical examples. Such level of drought knowledge became a basis for formulation of the new research project, trying to analyse the climate forcings and triggers involved in the occurrence, course and severity of drought events in the Czech Republic in the context of Central Europe and explanations of their physical mechanisms, based on a 515-year series of drought indices reconstructed from documentary and instrumental data. Presentation of this new project for 2017-2019 is included in the second part of the paper.

Water erosion is a main factor of degradation of soils used for agriculture in the Czech Republic. For landscape conservation purposes the soil erosion risk is defined here mostly by USLE (Wischmeier and Smith, 1978). Within USLE the precipitation impact on erosion is a function of rainfall kinetic energy and intensity represented by R-factor. In the Czech Republic historically and recently several research teams have analyzed rainfall data to assess R-factor. Till now not many European countries have performed detailed spatially distributed analyses of rain erosivities. Most studies use only simplified methods based on long-term rainfall averages or databases of only several station-datasets. The most recent study on rainfall erosivity spatial distribution over the Czech Republic was based on digital rain gauge data from automatic stations of the Czech Hydrometeorogical Institute. The erosive rains were derived from continuous 1 minute step 10-year rainfall data (2003-2012) from 245 stations. Based on the research recent annual R-factor values in the stations vary from 37 to 239 [N.h-1] (values over 100 are located in mountain regions with minimum of agricultural land). Average value is 69 [N.h-1.year-1]. For the Czech Republic the future prediction is based on 10km resolution ALADIN/CZ regional climate model. Within the EU FP6 project CECILIA it was coupled with GCM ARPEGE to provide a projection of future climate in two time slices, 2021-2050 and 2071-2100, according to the IPCC A1B emission scenario. Daily precipitation volumes and percentiles of maximal events allowed authors to develop R-factor maps of present and future scenarios. Based on the analyses we can conclude that average value for the whole territory of the Czech Republic will remain close to 70 [N.h-1.year-1] or even decrease for 2071-2100, but we can expect significant changes (30-40 % rise or decrease) for several large agricultural regions (eg. Southern Moravia). These changes will have impact on soil erosion dynamics of the specific areas. Details on the spatial distribution of recent and future rain erosivities over the Czech Republic and the consequences for the erosion risk will be presented. The paper was prepared within the projects NAZV QJ1230056 and BV VG 20122015092.

An ecological overview of seven years investigation of Braconidae, a family of parasitoid wasps (Hymenoptera: Ichneumonoidea) and a tyrpho-classification of parasitoids in peatbog areas of South Bohemia, Czech Republic are given. A total of 350 species were recorded in investigated sites, but only five tyrphobionts (1.4%) are proposed: Microchelonus basalis, Microchelonus koponeni, Coloneura ate, Coloneura danica and Myiocephalus niger. All of these species have a boreal-alpine distribution that, in Central Europe, is associated only with peatbogs. Tyrphophilous behaviour is seen in at least four (1.1%) species: Microchelonus pedator, Microchelonus subpedator, Microchelonus karadagi and Microchelonus gravenhorstii; however, a number of other braconids prefer peatbogs because they were more frequently encountered within, rather than outside, the bog habitat. The rest of the braconids (342 species, 97.5%) are tyrphoneutrals, many of them being eurytopic components of various habitats throughout their current ranges. Lists of tyrphobiontic braconids and a brief commentary on species composition, distributional picture of actual ranges, and parasitoid association to bog landscape are provided. Being true refugial habitats for populations in an ever-changing world, peatbogs play a significant role in harboring insect communities. PMID:20578880

Frequency Dependent Susceptibility Analysis of Magnetic Carriers: Application to Fe-Oxides on Mars surface

NASA Astrophysics Data System (ADS)

Adachi, T.; Kletetschka, G.; Mikula, V.

2007-12-01

On Mars, Fe-oxides mineral phases (inferred/detected) are mainly magnetite, pyrrhotite, and hematite. Kletetschka et al., 2005 suggested that the grain size dependent potential may contribute to the Mars surface magnetic anomaly. Grain size of Fe-oxides may play a role for the magnetic signature and anomaly on Mars. According to Kletetschka et al., 2005, the larger the grain size, the larger the magnetization (in this case hematite's TRM). Weather they are magnetite, pyrrhotite or hematite, nano-phase or superparamagnetic grains may contribute to the absence of remanent magnetization on the surface of Mars. In this contribution we tackle how to resolve grain size variations by frequency dependent susceptibility measured on terrestrial hematite samples such as hemo-ilmenite from Allard Lake, Canada, Mars analogue concretions from Utah and Czech Republic, and hematite aggregates from Hawaii. The magnetic characteristics of hematite-goethite mineralogies of Utah and Czech concretions suggested (Adachi et al., 2007) that they contain super paramagnetic (SP) to single domain (SD) magnetic states. Coercivity spectra analysis from acquisition of isothermal remanent magnetization (IRM) data showed the distinct behaviors of hematite, goethite, and mixed composition of both. The estimated magnetic states are analyzed with the frequency-dependent susceptibility instrument (500-250,000 Hertz). The frequency- and size-dependent susceptibility for hematite, goethite, and magnetite are calibrated using the known size powdered (commercial) samples.

Does brand differentiate pharmaceuticals?

Bednarik, Josef

2005-12-01

Role of marketing in pharmaceutical industry is increasing and inspiration by successful brands known from consumer goods market influenced pharmaceutical companies enough to switch their attention to branding initiatives. Still there is little evidence that pharmaceutical brands represent anything more than product only. This study aims to explore the area of branding in pharmaceutical industry. Central hypothesis of the research has been that brand and its emotional content differentiate pharmaceuticals as well as rational data derived from clinical studies. It has been tested by extensive review of available literature as well as by primary research focused on drivers of physicians' attitudes towards products and their influence on prescribing behavior. The research has been conducted in the sample of psychiatrists in the Czech Republic. No evidence about pharmaceutical brand exceeding value of product has been found in reviewed literature. Nevertheless, the primary research conducted in the sample of Czech psychiatrists indicates that emotional brand in pharmaceutical industry exists and enables author to draw a model of Customer/product life cycle that describes likely impact of functional, emotional and self-expressive benefits throughout pharmaceutical product's market presence. Pharmaceutical brand is likely to develop differently than the same of consumer goods products--it seems to be built predominantly on long-term positive experience. Marketing role in this process should lie in finding relevant product position and building brand identity compliant with real product capabilities.

A screening of more than 300 pollutants such as pharmaceuticals (analgesics, psycholeptics, antidepressants, antibiotics, beta blockers), PCPs (UV blockers, musk's, repellents), illicit drugs, pesticides, perfluorinated compounds and their metabolites at 22 monitoring sites throughout the Czech Republic was conducted in 2013. POCIS samplers were used in this study. Two types of passive samplers (pesticide and pharmaceutical POCIS) were deployed for 14 days in May and in October, 88 samples were collected in total. In total 265 and 310 target compounds were analyzed in pharmaceutical and pesticide samplers respectively. The chemicals of interest were extracted from the passive samplers according to standardized procedures. LC -MS/MS and LC-MS/HRMS methods were applied for analyses of extracts. 150 of 310 (48%) and 127 of 265 (48%) analyzed substances had been found in pesticide and pharmaceutical samplers respectively. 27 substances (pharmaceuticals, PCPs, pesticides, caffeine, nicotine metabolite cotinine) occurred at all sampled sites, additional 39 substances (pharmaceuticals, PCPs, pesticides) occurred at more than 17 (75%) sites. One of perfluorinated compounds (PFOA) occurred at 68% of sites, whilst one of illicit drugs (Methamphetamine) was found at 61% of sites. The highest number of contaminants found in one POCIS at a single monitoring site was 111. The concentrations varied from nanograms to thousands of nanograms per sampler. Emerging contaminants occurring in highest concentrations (> 1000 ng/sampler) were BP-4 and PBSA (UV blockers), caffeine, DEET (insect repellent), imidacloprid (insecticide), telmisartan (hypertension drug) and tramadol (analgesic). Monitoring in the Czech Republic has demonstrated that many target compounds enter river waters and a number of these compounds reach high concentrations.

He was one of the founders of gastroenterology in Czechoslovakia. He had been habilitated in 1948 for thesis Ulcerative colitis. Mařatka stood at the first steps of foundation of Czech Gastroenterology Society very soon after the WW2 and followed with the preparation as a secretary ge-neral of the 8th ASNEMGE Congress in Prague 1968 and as a president the 1st Congress of Endoscopy in the very optimistic atmosphere of ,,Prague Spring". He was nominated or elected by several international gastroenterology organisations, during 1976-1980 had been President of ESGE. He started with editoring of Czech gastroenterology Association journal as a member of editorial board and had been its main editor between 1969-1999. His well appreciated novelty in the magazine was a short remarks in one or two sentences from the world scientific literature which appeared in every copy. As an editor emeritus he supported the quality of the journal by many advices and contributions including articles.

The approaches to the didactics of physics in the Czech Republic - Historical development

Žák, Vojtěch

2017-01-01

The aim of this paper is to describe approaches to the didactics of physics which have appeared in the Czech Republic during its development and to discuss mainly their relationships with other fields. It is potentially beneficial to the understanding of the current situation of the Czech didactics of physics and to the prognosis of its future development. The main part of the article includes a description of the particular approaches of the Czech didactics of physics, such as the methodological, application, integration and communication approaches described in chronological order. Special attention is paid to the relationships of the didactics of physics and physics itself, pedagogy and other fields. It is obvious that the methodological approach is narrowly connected to physics, while the application approach comes essentially from pedagogy. The integration approach seeks the utilization of other scientific fields to develop the didactics of physics. It was revealed that the most elaborate is the communication approach. This approach belongs to the concepts that have influenced the current didactical thinking in the Czech Republic to a high extent in other fields as well (including within the didactics of socio-humanist fields). In spite of the importance of the communication approach, it should be admitted that the other approaches are, to a certain extent, employed as well and co-exist.

Valuation of Mortality Risk Attributable to Climate Change: Investigating the Effect of Survey Administration Modes on a VSL

2012-01-01

The health impact attributable to climate change has been identified as one of the priority areas for impact assessment. The main goal of this paper is to estimate the monetary value of one key health effect, which is premature mortality. Specifically, our goal is to derive the value of a statistical life from people’s willingness to pay for avoiding the risk of dying in one post-transition country in Europe, i.e., the Czech Republic. We carried out a series of conjoint choice experiments in order to value mortality risk reductions. We found the responses to the conjoint choice questions to be reasonable and consistent with the economic paradigm. The VSL is about EUR 2.4 million, and our estimate is comparable with the value of preventing a fatality as used in one of the integrated assessment models. To investigate whether carrying out the survey through the internet may violate the welfare estimate, we administered our questionnaire to two independent samples of respondents using two different modes of survey administration. The results show that the VSLs for the two groups of respondents are €2.25 and €2.55 million, and these figures are statistically indistinguishable. However, the key parameters of indirect utility between the two modes of survey administration are statistically different when specific subgroups of population, such as older respondents, are concerned. Based on this evidence, we conclude that properly designed and administered on-line surveys are a reliable method for administering questionnaires, even when the latter are cognitively challenging. However, attention should be paid to sampling and choice regarding the mode of survey administration if the preference of specific segments of the population is elicited. PMID:23249861

A novel rickettsial sequence in the citrate synthase gltA gene indicating a novel Rickettsia species has been detected in 7 out of 4524 Ixodes ricinus ticks examined within several surveys performed in the Czech Republic from 2005 to 2009. This new Candidatus Rickettsia sp. sequence has been found in 2 nymphs feeding on wild birds (Luscinia megarhynchos and Erithacus rubecula), in a male tick from vegetation, and 4 ticks feeding on a dog (3 males, 1 female tick). Portions of the ompA, ompB, sca4, and htrA genes were not amplifiable in these samples. A maximum likelihood tree of rickettsiae based on comparisons of partial amino acid sequences of citrate synthase and nucleotide sequences of 16S rDNA genes and phylogenetic analysis revealed a basal position of the novel species in the proximity of R. bellii and R. canadensis. The novel species has been named 'Candidatus Rickettsia mendelii' after the founder of genetics, Gregor Mendel. Copyright © 2016 Elsevier GmbH. All rights reserved.

A large outbreak caused by a rare Shiga toxin-producing Escherichia coli serotype O104:H4 occurred in Germany in May to July 2011. The National Reference Laboratory for E. coli and Shigella investigated the stool sample from an American tourist with bloody diarrhea who arrived in the Czech Republic from Germany where she consumed salads with raw vegetable a week ago. Using culture of the enriched stool on extended-spectrum β-lactamase agar, we isolated E. coli strain which belonged to serotype O104:H4 as determined by conventional and molecular serotyping. The strain contained the major virulence characteristics of enterohemorrhagic E. coli (stx (2) encoding Shiga toxin 2) and enteroaggregative E. coli (aggA encoding aggregative adherence fimbriae I). This unique combination of virulence traits demonstrated that this strain belongs to the hybrid enteroaggregative hemorrhagic E. coli clone which caused the German outbreak. Using advanced culture and molecular biological approaches is the prerequisite for identification of new, unusual pathogens.

Dissolved waterborne polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) were assessed over a period of one year at five sampling sites in a model industrial region in the Czech Republic using silicone rubber passive samplers. The spatial variability of POPs in the studied region in water was small and diffusive pollution sources predominate. Concentrations of the most volatile PAHs decreased with increasing water temperature in the whole region, which reflects the seasonality in atmospheric deposition. The dissolved concentrations of more hydrophobic PAHs, PCBs and OCPs in and downstream the industrial zone are related to desorption from suspended particles. Upstream the industrial area, a positive correlation of dissolved and particle-bound contamination was observed only for DDT metabolites and hexachlorobenzene. Calculated fugacities in water and bottom sediment indicated a fair degree of equilibrium between these compartments for OCPs and PCBs, whereas sediment represented a potential source of PAHs.

Application of X-ray diffraction (XRD)-based techniques in the analysis of painted artworks is not only beneficial for indisputable identification of crystal constituents in colour layers, but it can also bring insight in material crystal structure, which can be affected by their geological formation, manufacturing procedure or secondary changes. This knowledge might be helpful for art historic evaluation of an artwork as well as for its conservation. By way of example of kaolinite, we show that classification of its crystal structure order based on XRD data is useful for estimation of its provenance. We found kaolinite in the preparation layer of a Gothic wall painting in a Czech church situated near Karlovy Vary, where there are important kaolin deposits. Comparing reference kaolin materials from eight various Czech deposits, we found that these can be differentiated just according to the kaolinite crystallinity. Within this study, we compared laboratory powder X-ray micro-diffraction (micro-XRD) with synchrotron radiation X-ray diffraction analysing the same real sample. We found that both techniques led to the same results.

Acinetobacter baumannii is an opportunistic pathogen posing an increased risk to hospitalized persons, causing nosocomial pneumonias, urinary tract infections and postoperative infections. Between 1 December 2011 and 30 September 2012, strains of Acinetobacter spp. were isolated from clinical samples obtained from hospitalized patients. Susceptibility to antibiotics was determined by the standard microdilution method and phenotypic testing was used to detect the presence of serine carbapenemases and metallo-beta-lactamases. The polymerase chain reaction was used to detect the genes encoding carbapenemases. Pulsed field gel electrophoresis was used to investigate the genetic relationship among the carbapenem resistant isolates of Acinetobacter baumannii. In three strains of Acinetobacter baumannii enzyme OXA-23 was detected. This positive result was confirmed by restriction analysis and sequencing. The study reported an OXA-23-producing strains of Acinetobacter baumannii in the Czech Republic. All three strains isolated from Military Hospital patients had a completely identical restriction profile, indicating clonal spread of a strain carrying serine carbapenemase OXA-23 in this health care facility. Moreover this was the first time the strain was detected in the country in patients who had not stayed abroad.

Neutron radiography is an imaging method often used at research reactor sites. Back in 2011 a project was started with the goal to build a neutron radiography facility at the site of the LVR-15 research reactor in Rez, Czech Republic. In the scope of the project two horizontal channels were adapted for the needs of neutron radiography. This comprises the HC1 channel which offers an intense thermal neutron beam with a diameter of 10 cm, which can be used for imaging of larger samples, and the HC3 channel which beam is restricted just to 4x80 mm2, but is highly thermalized, collimated and reduced from gamma background, thus capable of providing better radiograph resolution. Both facilities are equipped with newest Timepix based detectors, with thin 6LiF converters for neutron detection capable of delivering high resolution. Both facilities offer a unique opportunity for non-destructive testing in the Czech region. In 2015 both facilities were put into test operation and several radiographs were acquired, which are presented in the following text.

Intraspecific variability in allelopathy of Heracleum mantegazzianum is linked to the metabolic profile of root exudates

2015-01-01

Background and Aims Allelopathy may drive invasions of some exotic plants, although empirical evidence for this theory remains largely inconclusive. This could be related to the large intraspecific variability of chemically mediated plant–plant interactions, which is poorly studied. This study addressed intraspecific variability in allelopathy of Heracleum mantegazzianum (giant hogweed), an invasive species with a considerable negative impact on native communities and ecosystems. Methods Bioassays were carried out to test the alleopathic effects of H. mantegazzianum root exudates on germination of Arabidopsis thaliana and Plantago lanceolata. Populations of H. mantegazzianum from the Czech Republic were sampled and variation in the phytotoxic effects of the exudates was partitioned between areas, populations within areas, and maternal lines. The composition of the root exudates was determined by metabolic profiling using ultra-high-performance liquid chromatography with time-of-flight mass spectrometry, and the relationships between the metabolic profiles and the effects observed in the bioassays were tested using orthogonal partial least-squares analysis. Key Results Variance partitioning indicated that the highest variance in phytotoxic effects was within populations. The inhibition of germination observed in the bioassay for the co-occurring native species P. lanceolata could be predicted by the metabolic profiles of the root exudates of particular maternal lines. Fifteen compounds associated with this inhibition were tentatively identified. Conclusions The results present strong evidence that intraspecific variability needs to be considered in research on allelopathy, and suggest that metabolic profiling provides an efficient tool for studying chemically mediated plant–plant interactions whenever unknown metabolites are involved.

Cordaites principalis and Cordaites borassifolius, gymnosperm trees of the Carboniferous, are distinguished based on compression and cuticular morphology. A new distinction between them is suggested on the basis of differences in functional groups. Cuticular and compression spectra of C. borassifolius have lower CH2/CH3 ratios, suggesting more branched aliphatic chains in comparison with cuticles and compressions of C. principalis. Other differences are observed with Fourier transform infrared spectroscopy (FTIR) technique, but they vary from sample to sample of the two species to suggest other than chemotaxonomic-based sources of variations. ?? 2003 Elsevier B.V.

Data analysis of the incidence, mortality and basic data regarding therapy of esophageal cancer in the Czech Republic and determining possible ways to improve the current situation. Analysis was performed using data obtained from the Czech National Cancer Registry and from the Registry of Thoracic Procedures from the Section of Thoracic Surgery of the Czech Surgical Society. Analysis of specialized literature provided generally accepted risk factors for the development of esophageal cancer. Esophageal cancer represents 0.7% of all solid malignant tumours in the Czech Republic (1.1% in males and 0.2% in females). During 1977 to 2008, the incidence increased from 2 to 5.4 cases per 100.000 inhabitants and mortality from 1.9 to 4.1 cases per 100.000 inhabitants. In absolute numbers, the incidence was 561 cases (5.4 per 100.000 inhabitants) in 2008. Absolute mortality rate was 452 deaths (4.3 per 100.000 inhabitants) and absolute prevalence (number of patients living with cancer or with its medical history) was 791 subjects(7.6 per 100.000 inhabitants). When compared to international data, the incidence in the Czech Republic is the 84th highest in the world and 17th highest in Europe (mortality rates are at the 85th place in the world and the 18th place in Europe). In the Czech Republic, the highest incidence is in the Moravian-Silesian and Zlin regions (6.1 per 100.000), the lowest in the Plzen (4.2) and Vysocina (4.1) regions. The average age at the time of diagnosis is 62 years in males and 68 years in females, the maximum incidence is between 55 and 69 years in males and between 58 and 79 years in females. Upon diagnosis, advanced stages of the disease predominate. In 2008, 28% of the detected esophageal cancer cases were stage I and II disorders, 60 % were stage III and IV disorders, and in 12% of the cases the stage was not determined. In the treated patient group, the five-year survival rate was 15.5% in total, based on an analysis of data from 2004 - 2007. The five-year survival was 30% in stage I and II diosease cases, 12% in stage III disorders and 2% in stage IV cases. When comparing the analysis of data from 2004 to 2007 with the analysis of data from 2000 to 2003, there is a 10% improvement in stages I and II and a 4% improvement in stage III disorders. According to the Thoracic Surgery Registry of Thoracic Procedures data covering the period 2007 to 2010, thoracic procedures are performed at 19 to 22 surgical departments, esophageal resections are performed at 13 to 14 surgical departments, but only in 8 to 9 of these departments is the frequency of such procedures more than 10 operations per year. At the authors' department, 53 esophageal resections have been performed in the past five years with a 3.8% postoperative mortality rate and a 23 % total postoperative morbidity rate. Forty-nine percent of the cases were adenocarcinomas. Based on its incidence in our population, esophageal cancer can be considered an unfrequent tumour. This analysis shows regions of the Czech Republic with higher incidence and the most at-risk age group in males. Significant risk factors for squamous cell cancer such as smoking and alcohol consumption have already been previously identified; in adenocarcinoma it is primarily Barrett's esophagus. Other risk groups include patients with achalasia and with strictures after corrosion injury to the esophagus. Acceptable treatment results may only be achieved in patients with less severe stages of the disease and it would therefore be appropriate to actively search for such patients in at-risk regions and among the risk groups as part of the preventive programs. To date, universally accepted guidelines for monitoring of such patients have not been defined. Surgical treatment is a highly specialized domain of thoracic surgeons focused on esophageal surgery and patients should be concentrated in specialized centres.

Analysis of the prevalence of selected congenital anomalies in the Czech Republic in 1994-2009. Retrospective epidemiological analysis of the postnatal and overall (including prenatally diagnosed cases) prevalence of congenital anomalies from the database of the National Registry of Congenital Anomalies of the Czech Republic. Data from the National Registry of Congenital Anomalies (NRCA) maintained by the Institute of Health Information and Statistics of the Czech Republic (IHIS CR) were used. The analysis was carried out for the entire Czech Republic, based on the data from 1994 to 2009. Additional data on prenatally diagnosed anomalies were obtained from medical genetics centres and laboratories in the Czech Republic. This study analyzed the postnatal and overall (including prenatally diagnosed cases) prevalence of congenital anomalies. More detailed analysis was carried out for the following diagnoses: anencephaly, spina bifida, encephalocoele, congenital hydrocephalus, omphalocoele, gastroschisis, oesophageal atresia and stenosis, anorectal anomalies, and diaphragmatic hernia. Prevalence trends were analysed using Poisson regression. In 2009, a total of 118 348 live births were recorded in the Czech Republic, 60 368 boys and 57 980 girls. Of this total, 4 653, i.e. 2 745 boys and 1 908 girls, were diagnosed with congenital anomalies. In 2007-2009, the total of life births with congenital anomalies ranged between 4.6 and 4.8 thousand per year. The respective ranges in this three-year period were in the order of 2.7 and 2.8 thousand per year for boys and 1.9 thousand per year for girls. The prevalence of postnatally diagnosed anencephaly was minimal, as most cases were diagnosed prenatally, and the data did not vary significantly. The prevalence of postnatally diagnosed cases remained at the same level. The effectiveness of the prenatal diagnosis of spina bifida increased and thus the prevalence of postnatally diagnosed cases decreased. The prevalence of prenatally diagnosed encephalocoele increased and that of postnatally diagnosed cases varied between years, with no clear trend. The prevalence of omphalocoele varied for both prenatally and postnatally diagnosed cases; nevertheless, the effectiveness of prenatal diagnosis of this defect increases. The prevalence of gastroschisis remained unchanged, but the number of live births with this diagnosis showed a non-significant upward trend. If the trend reflects the real situation, it could be a result of a changed approach to prenatal diagnosis due to advances in corrective surgery of this defect. The prevalence of live births with congenital hydrocephalus showed a downward trend in the second half of the period 1994-2009 thanks to the improved diagnosis. The prevalence rates of live births with congenital esophageal and anorectal anomalies were slightly increasing. The prevalence of congenital diaphragmatic hernia varied between years but the overall prevalence appeared to be slightly increasing. The prevalence of some congenital anomalies (spina bifida, omphalocoele, and congenital hydrocephalus) showed a downward trend over the study period 1994-2009, mainly as a result of effective prenatal diagnosis. The prevalence of other congenital anomalies such as anencephaly or encephalocoele remained unchanged in live births. As for anencephaly, postnatally diagnosed cases were rare as the prenatal diagnosis was close to 100 %. The trend in encephalocoele is explained by the low incidence of this diagnosis in the population. The third group of postnatally diagnosed congenital anomalies such as gastroschisis or esophageal and anorectal anomalies were on the rise. As for gastroschisis, the reason was the changed approach to prenatal diagnosis due to good prognosis of this operable defect. The prevalence of congenital esophageal and anorectal anomalies varied between years, with a slowly increasing trend, similarly to diaphragmatic hernia.

This investigation examined to what extent a selected group of immigrants in the Czech Republic receive healthcare for primary prevention and inpatient care. A partial aim of the research was to confirm the connection between immigrant health and their social situation. Using a quantitative study technique, 1,014 legally established immigrants (Vietnamese, Polish, Ukrainian, Russian, and Slovak) between 18-65 years of age were interviewed. The selection of respondents was conducted using purposive selection. The stratification of the group was determined by nationality, age, and gender. Long-term illnesses were found significantly more frequently among Ukrainian immigrants and less frequently among Vietnamese immigrants. About half of the respondents had visited a GP and dentist in the previous year and 11.5% of respondents had been hospitalized in inpatient departments. Most of the surveyed immigrants had public health insurance (77.9%), one-fifth had contractual health insurance (19.6%) and 2.5% did not have health insurance. In statistical terms, Vietnamese, Ukrainian, and Russian immigrants had commercial insurance more often than Polish and Slovak immigrants. The utilization of public health insurance and healthcare among immigrants grew significantly in correlation with length of residency. The use of GPs for preventive health care also grew in correlation with knowledge of the Czech language. We found that less than nine percent of immigrants reported needing hospitalization for an illness, but were not hospitalized. Currently, immigration represents one of the most burning and sensitive global challenges. The outcome of this research clearly shows that improving immigrant Czech language skills and giving all legally established immigrants access to Czech public health insurance are important steps needed to increase access to healthcare for immigrants in the Czech Republic.

There is limited research examining the chemical load of toxic metals in the elderly. The aim of the present study was two-fold: to determine the body burden of lead, cadmium and mercury in association with age, gender, locality, lifestyle factors and potential health impacts among this population and to compare the values with blood values from the general Czech population aged 18-64 years. Lead, cadmium and mercury were examined in the blood of institutionalized senior citizens (46 males, 151 females aged 61-100 years) from two localities in the Czech Republic (Prague and Teplice) from 2009 through 2011. Measurements were made using inductively coupled plasma mass spectrometry (Pb, Cd) and a single purpose spectrometer AMA 254 (Hg). Geometric means (GM) of whole blood lead (B-Pb), cadmium (B-Cd) and mercury (B-Hg) levels were 25.3μg/l, 0.55μg/l and 0.21μg/l, respectively. No age-related differences were found for B-Pb and B-Cd levels but a negative correlation with age was observed for B-Hg levels (p=0.04). B-Pb levels in men were significantly higher than in women (GM 29.9μg/l vs. 24.1μg/l). B-Cd was significantly higher in women (GM 0.57μg/l) than in men (0.50μg/l) (p=0.007) and in smokers (GM 1.29μg/l) than in nonsmokers (GM 0.53μg/l) (p=<0.001) and in seniors from Prague (GM 0.60μg/l) compared to those from Teplice (GM 0.43μg/l) (p=<0.001). Seniors with a history of chronic kidney disease, stroke and those using psycho-pharmaceuticals had higher B-Pb levels (p=0.008, 0.04 and 0.05, resp.), seniors diagnosed with atherosclerosis had higher B-Cd levels (p=0.002) and seniors using psycho-pharmaceuticals had higher B-Hg levels (p=0.07). B-Hg levels were also positively correlated with blood albumin levels (p=0.015). This study provides data on levels of heavy metals in a group of elderly people. Such information is very scarce. Associations with diseases should be the subject of further investigation. Copyright © 2014 Elsevier Inc. All rights reserved.

Consumers' beliefs and behavioural intentions towards organic food. Evidence from the Czech Republic.

PubMed

Zagata, Lukas

2012-08-01

Research has revealed that organic consumers share beliefs about positive health effects, environmentally friendly production and better taste of organic food. Yet, very little is known about the decisions of organic consumers in post-socialist countries with emerging organic food markets. In order to examine this area a representative data set (N=1054) from the Czech Republic was used. Target group of the study has become the Czech consumers that purchase organic food on regular basis. The consumers' behaviour was conceptualised with the use of the theory of planned behaviour (ToPB). Firstly, the ToPB model was tested, and secondly, belief-based factors that influence the decisions and behaviour of consumers were explored. The theory proved able to predict and explain the behaviour of Czech organic consumers. The best predictors of the intention to purchase organic food are attitudes towards the behaviour and subjective norms. Decisive positions in consumers' beliefs have product- and process-based qualities. Copyright © 2012 Elsevier Ltd. All rights reserved.

Pre-attentive sensitivity to vowel duration reveals native phonology and predicts learning of second-language sounds.

PubMed

Chládková, Kateřina; Escudero, Paola; Lipski, Silvia C

2013-09-01

In some languages (e.g. Czech), changes in vowel duration affect word meaning, while in others (e.g. Spanish) they do not. Yet for other languages (e.g. Dutch), the linguistic role of vowel duration remains unclear. To reveal whether Dutch represents vowel length in its phonology, we compared auditory pre-attentive duration processing in native and non-native vowels across Dutch, Czech, and Spanish. Dutch duration sensitivity patterned with Czech but was larger than Spanish in the native vowel, while it was smaller than Czech and Spanish in the non-native vowel. An interpretation of these findings suggests that in Dutch, duration is used phonemically but it might be relevant for the identity of certain native vowels only. Furthermore, the finding that Spanish listeners are more sensitive to duration in non-native than in native vowels indicates that a lack of duration differences in one's native language could be beneficial for second-language learning.

Pharmacists can own and manage community pharmacies, or work as responsible pharmacists in pharmacies. All practising pharmacists must be registered with the Czech Chamber of Pharmacists. The ownership of a community pharmacy is not restricted to members of the pharmacy profession; the majority of pharmacies are organised into various pharmacy chains. There are two universities providing higher education in pharmacy in the Czech Republic: the Faculty of Pharmacy in Hradec Kralove, Charles University, which was established in 1969, and the Faculty of Pharmacy of the University of Veterinary and Pharmaceutical Sciences in Brno, which was established in 1991. The pharmacy curriculum is organized as a seamless, fully integrated, five-year master degree course. There is a six-month traineeship supervised by the university, which usually takes place during the fifth year.

A brief review of application of X-ray fluorescence analysis (XRFA) to fine and applied arts related to Czech cultural heritage is presented. The Department of Dosimetry and Application of Ionising Radiation of CTU-FNSPE has used XRFA in collaboration with various Czech institutions dealing with cultural history for many kinds of artefacts, (e.g., Roman and medieval brass, gemstones and noble metals from the sceptre of one of the faculties of the Charles University in Prague, millefiori beads, etc.). In some cases, a combination of various other techniques alongside XRFA was used for enhancing our knowledge of a measured object.

Reconstruction of two colonisation pathways of Mantis religiosa (Mantodea) in Germany using four mitochondrial markers.

Linn, Catherine Anne; Griebeler, Eva Maria

Past and recent climatic changes induced shifts in species ranges. Mantis religiosa has also expanded its range across Germany within the past decades. To determine the ancestry of German M. religiosa we sequenced four mitochondrial genes (COI, COII, Cyt b, ND4) of European M. religiosa populations. We found an east, central and west European lineage of M. religiosa. These distinct lineages are consistent with genetic isolation by distance during glacial periods, and the re-colonization of northern parts of Europe by species from different refugia. Within Germany, we found haplotypes clustering to the central and west European lineage suggesting that M. religiosa immigrated from two directions into Germany. Mismatch distributions, and negative Tajima's D and Fu's Fs values indicate a current range expansion of the central and west European lineage. We hypothesise that ongoing global warming which increases the availability of thermally favourable areas in Germany for M. religiosa adds to its current range expansion. In conclusion, M. religiosa colonized Germany via two directions: west German populations descended from French populations and east German populations from Czech populations.

A comparison of lead pollution record in Sphagnum peat with known historical Pb emission rates in the British Isles and the Czech Republic

Novak, Martin; Erel, Yigal; Zemanova, Leona; Bottrell, Simon H.; Adamova, Marie

Vertical Pb concentration gradients and isotope ratios ( 206Pb/ 207Pb, 208Pb/ 207Pb) are reported for five 210Pb-dated Sphagnum peat profiles. The studied peat bogs are in the British Isles (Thorne Moors, England; Mull, Scotland; and Connemara, Eire) and central Europe (Ocean, northern Czech Republic; Rybarenska slat, southern Czech Republic). Both the U.K. and the Czech Republic experienced maximum Pb emissions from Ag-Pb smelting around 1880. Pb emissions from coal burning peaked in 1955 in the U.K. and in the 1980s in the Czech Republic. In both countries, use of alkyl-lead additives to gasoline resulted in large Pb emissions between 1950 and 2000. We hypothesized that peaks in Pb emissions from smelting, coal burning and gasoline burning, respectively, should be mirrored in the peat profiles. However, a more complicated pattern emerged. Maximum annual Pb accumulation rates occurred in 1870 at Ocean, 1940 at Thorne Moors, 1988 at Rybarenska slat, and 1990 at Mull and Connemara. Atmospheric Pb inputs decreased in the order Thorne Moors ≥ Ocean > Rybarenska slat > Mull > Connemara. The Ocean bog was unique in the central European region in that its maximum Pb pollution dated back to the 19th century and coincided with maximum Pb smelting at Freiberg and Pribram. In contrast, numerous previously studied sites showed no Pb accumulation maximum in the 19th century, but increasing pollution until the 1980s. It remains unclear why Ocean did not record the regional peak in Pb emissions caused by high coal and gasoline burning around 1980, while an array of nearby bogs studied previously did record the 1980 coal/gasoline peak, but no 1880 smelting peak. Mean 206Pb/ 207Pb ratios of potential pollution sources were 1.07 and 1.11 for gasoline, 1.17 and 1.17 for local ores, and 1.18 and 1.19 for coal in the U.K. and the Czech Republic, respectively. The calculated percentages of gasoline-derived Pb in peat (≤55% for the British Isles and ≤63% for the Czech Republic) were surprisingly low. An explanation for the low percentage of gasoline-derived Pb in peat can be more easily found for the Czech sites (until 1989 Czechoslovakia was the third largest lignite producer in the world). Regional differences in deposition rates of gasoline-derived Pb in the U.K. need further study.

This study addresses the reconstruction of four slightly different drought indices in the Czech Lands (recent Czech Republic) back to 1501 AD. Reconstructed monthly temperatures for central Europe that are representative for the Czech territory, together with reconstructed seasonal precipitation totals from the same area, are used to calculate monthly, seasonal and annual drought indices (SPI, SPEI, Z-index, and PDSI). The resulting time-series reflect interannual-to multi-decadal drought variability. The driest episodes cluster around the beginning and end of the 18th century, while 1540 emerges as a particularly dry extreme year. The temperature-driven dryness of the past three decades is well captured by SPEI, Z-index and PDSI, whereas precipitation totals show no significant trend during this period (as reflected in SPI). Data and methodological uncertainty associated with Czech drought indices, as well as their position in a greater European context, are critically outlined. Further discussion is devoted to comparison with fir tree-rings from southern Moravia and a spatial subset of the "Old World Drought Atlas" (OWDA), which reveals significant correlation coefficients, of around 0.40 and 0.50, respectively. This study introduces a new documentary-based approach for the robust extension of standardized drought indices back into pre-instrumental times, which we also believe has great potential in other parts of the world where high-resolution paleoclimatic insight remains as yet limited.

The aim of this contribution is to introduce the recently started three year's project named "Variability of Short-term Precipitation and Runoff in Small Czech Drainage Basins and its Influence on Water Resources Management". Its main goal is to elaborate a methodology and online utility for deriving short-term design precipitation series, which could be utilized by a broad community of scientists, state administration as well as design planners. The outcomes of the project will especially be helpful in modelling hydrological or soil erosion problems when designing common measures for promoting water retention or landscape drainage systems in or out of the scope of Landscape consolidation projects. The precipitation scenarios will be derived from 10 years of observed data from point gauging stations and radar data. The analysis is focused on events' return period, rainfall total amount, internal intensity distribution and spatial distribution over the area of Czech Republic. The methodology will account for the choice of the simulation model. Several representatives of practically oriented models will be tested for the output sensitivity to selected precipitation scenario comparing to variability connected with other inputs uncertainty. The variability of the outputs will also be assessed in the context of economic impacts in design of landscape water structures or mitigation measures. The research was supported by the grant QJ1520265 of the Czech Ministry of Agriculture, using data provided by the Czech Hydrometeorological Institute.

Purpose Chronic obstructive pulmonary disease (COPD) has been recognized as a heterogeneous, multiple organ system-affecting disorder. The Global Initiative for Chronic Obstructive Lung Disease (GOLD) places emphasis on symptom and exacerbation management. The aim of this study is examine the course of COPD and its impact on morbidity and all-cause mortality of patients, with respect to individual phenotypes and GOLD categories. This study will also evaluate COPD real-life patient care in the Czech Republic. Patients and methods The Czech Multicentre Research Database of COPD is projected to last for 5 years, with the aim of enrolling 1,000 patients. This is a multicenter, observational, and prospective study of patients with severe COPD (post-bronchodilator forced expiratory volume in 1 second ≤60%). Every consecutive patient, who fulfils the inclusion criteria, is asked to participate in the study. Patient recruitment is done on the basis of signed informed consent. The study was approved by the Multicentre Ethical Committee in Brno, Czech Republic. Results The objective of this paper was to outline the methodology of this study. Conclusion The establishment of the database is a useful step in improving care for COPD subjects. Additionally, it will serve as a source of data elucidating the natural course of COPD, comorbidities, and overall impact on the patients. Moreover, it will provide information on the diverse course of the COPD syndrome in the Czech Republic. PMID:25419124

The Fundamental Spatial Data in the Public Administration Registers

Čada, V.; Janečka, K.

2016-06-01

The system of basic registers was launched in the Czech Republic in 2012. The system provides a unique solution to centralize and keep actual most common and widely used information as a part of the eGovernment. The basic registers are the central information source for information systems of public authorities. In October 2014, the Czech government approved the conception of The Strategy for the Development of the Infrastructure for Spatial Information in the Czech Republic to 2020 (GeoInfoStrategy) that serves as a basis for the NSDI. The paper describes the challenges in building the National Spatial Data Infrastructure (NSDI) in the Czech Republic with focus on the fundamental spatial data and related basic registers. The GeoInfoStrategy should also contribute to increasing of the competitiveness of the economy. Therefore the paper also reflects the Directive 2014/61/EU of the European Parliament and of the Council on measures to reduce the cost of deploying high-speed electronic communication networks. The Directive states that citizens as well as the private and public sectors must have the opportunity to be part of the digital economy. A high quality digital infrastructure underpins virtually all sectors of a modern and innovative economy. To ensure a development of such infrastructure in the Czech Republic, the Register of passive infrastructure providing information on the features of passive infrastructure has to be established.

The healthcare sector ranked in second place among economic sectors in the Czech Republic, with about 11.4 % of all occupational diseases in 2009. Skin diseases constituted about 20 % of all occupational diseases. The aim of this study was to analyze the causes and trends in allergic and irritant-induced skin diseases in the healthcare sector. The data concerning occupational skin diseases (Chapter IV of the Czech List of Occupational Diseases, non-infectious skin illnesses) in the healthcare sector were analyzed from the Czech National Registry of Occupational Diseases from 1997 until 2009. The trends in the total counts and most frequent causes were evaluated. During the past 13 years, a total of 545 skin diseases were acknowledged in healthcare workers. Allergic contact dermatitis was diagnosed in 464 (85 %), irritant contact dermatitis in 71 (13 %) and contact urticaria in 10 subjects (2 %). Ninety-five percent of the patients were females. The overall incidence in individual years varied between 1.0 and 2.9 cases per 10,000 full-time employees per year. Disinfectants were the most frequent chemical agents causing more than one third of all allergic skin diseases (38 %), followed by rubber components (32 %) and cleaning agents (10 %). A general downward trend of diagnosed cases of occupational skin diseases in heath care workers in the Czech Republic over the past 13 years was demonstrated.

The transplantation of fresh or cryopreserved vascular allografts in patients with a prosthetic graft infection or critical limb ischemia is necessary for their limb salvage and, in many cases, represents a lifesaving procedure. While transplantation of fresh allografts has a long history in the Czech Republic, the standard use of cryopreserved vascular allografts was introduced into the clinical practice in 2011 as a result of the implementation of EU Directive 2004/23/EC into national legislation (Human Cell and Tissue Act No. 296/2008 Coll.). The authors present an organizational model based on cooperation between the majority of Czech Transplant Centers with a tissue establishment licensed by the national competent authority. In various points, we are addressing individual aspects of experimental and clinical studies which affect clinical practice. Based on experimental and clinical work, the first validation of cryopreserved arterial and venous grafts for clinical use was performed between 2011 and 2013. The growing number of centers participating in this programme led to a growing number of patients who underwent transplantation of vascular allografts. In 2015 the numbers of transplanted fresh versus cryopreserved allografts in the Czech Republic were almost equal. Cooperation of the participating centers in the Czech Republic with the licensed Tissue Establishment made it possible to achieve a full compliance with the European Union Directives, and harmonized national legal norms and assured a high quality of cryopreserved vascular allografts.

Carbapenemase-producing Enterobacteriaceae and Pseudomonas spp. are increasingly reported in many countries all over the world. Due to the resistance of those bacteria to almost all antibiotics (e.g.beta-lactams, aminoglycosides, fluoroquinolones),treatment options are seriously limited. In the Czech Republic, the incidence of carbapenemase-producing Enterobacteriaceae seems to be low, restricted to only three cases detected between 2009 and 2010.Here, we describe molecular typing of 15 carbapenemase-producing Klebsiella pneumoniae isolates identified in the Czech Republic during 2011. Five VIM-1-producing isolates belonging to sequence type (ST)11 and one VIM-4-producing isolate of ST1029 have been detected. blaVIM-1 and blaVIM-4 as a part of class 1 integrons were chromosomally located or carried by a plasmid belonging to A/C replicon type (blaVIM-4). KPC-3-producing isolates of ST512, recovered from six patients, caused an outbreak. Three more isolates producing KPC-2 enzyme belonged to ST258. Both blaKPCgenes were part of the Tn4401a transposon carried on plasmids of the pKpQIL type. The isolates were resistant to all antibiotics tested except colistin and/or gentamicin.Four of these 15 strains were recovered from patients repatriated to the Czech Republic from Greece and Italy. This is the first report of outbreaks caused by carbapenemase-producing Enterobacteriaceae in the Czech Republic.

Background This study presents antigenic and genetic characteristics of Neisseria meningitidis strains recovered from invasive meningococcal disease (IMD) in the Czech Republic in 1971–2015. Material and Methods A total of 1970 isolates from IMD, referred to the National Reference Laboratory for Meningococcal Infections in 1971–2015, were studied. All isolates were identified and characterized by conventional biochemical and serological tests. Most isolates (82.5%) were characterized by multilocus sequence typing method. Results In the study period 1971–2015, the leading serogroup was B (52.4%), most often assigned to clonal complexes cc32, cc41/44, cc18, and cc269. A significant percentage of strains were of serogroup C (41.4%), with high clonal homogeneity due to hyperinvasive complex cc11, which played an important role in IMD in the Czech Republic in the mid-1990s. Serogroup Y isolates, mostly assigned to cc23, and isolates of clonally homogeneous serogroup W have also been recovered more often over the last years. Conclusion The incidence of IMD and distribution of serogroups and clonal complexes of N. meningitidis in the Czech Republic varied over time, as can be seen from the long-term monitoring, including molecular surveillance data. Data from the conventional and molecular IMD surveillance are helpful in refining the antimeningococcal vaccination strategy in the Czech Republic. PMID:27936105

Methodological issues affecting the study of fish parasites. II. Sampling method affects ectoparasite studies.

Kvach, Yuriy; Ondračková, Markéta; Janáč, Michal; Jurajda, Pavel

2016-08-31

In this study, we assessed the impact of sampling method on the results of fish ectoparasite studies. Common roach Rutilus rutilus were sampled from the same gravel pit in the River Dyje flood plain (Czech Republic) using 3 different sampling methods, i.e. electrofishing, beach seining and gill-netting, and were examined for ectoparasites. Not only did fish caught by electrofishing have more of the most abundant parasites (Trichodina spp., Gyrodactylus spp.) than those caught by beach seining or gill-netting, they also had relatively rich parasite infracommunities, resulting in a significantly different assemblage composition, presumably as parasites were lost through handling and 'manipulation' in the net. Based on this, we recommend electrofishing as the most suitable method to sample fish for parasite community studies, as data from fish caught with gill-nets and beach seines will provide a biased picture of the ectoparasite community, underestimating ectoparasite abundance and infracommunity species richness.

Samples of lichens, snow and particulate matter (PM 10 , 24 h) are used for the source identification of air pollution in the heavily industrialized region of Ostrava, Upper Silesia, Czech Republic. An integrated approach that uses different environmental samples for metal concentration and Pb isotope analyses was applied. The broad range of isotope ratios in the samples indicates a combination of different pollution sources, the strongest among them being the metallurgical industry, bituminous coal combustion and traffic. Snow samples are proven as the most relevant indicator for tracing metal(loid)s and recent local contamination in the atmosphere. Lichens can be successfully used as tracers of the long-term activity of local and remote sources of contamination. The combination of PM 10 with snow can provide very useful information for evaluation of current pollution sources. Copyright © 2016 Elsevier Ltd. All rights reserved.

To characterize the oral health-related attitudes and behaviour of Czech parents of preschool children. A representative sample of 796 parents was recruited for the cross-sectional questionnaire survey. Study data were collected using a validated questionnaire with 44 attitudinal items related to different aspects of caries prevention. The data were analyzed by explorative factor analysis, extracted factors were subjected to reliability analysis and Kruskal-Wallis ANOVA was used to test differences in the factor scores in respondents with different levels of education and self-perceived SES. The factor analysis extracted 3 factors, labelled "Toothbrushing - perceived significance and parental efficacy" ; "External caries control" and "Internal caries control". They explained 28.9% of the data variability. The comparison of the factor scores in groups with different SES and education of mothers showed highly significant differences. For all three factors, median values of the aggregated Likert scale increased with increasing SES and education of the mother. The parents report that they are aware of their responsibility for the prevention of tooth decay in their children. In caries prevention they concentrate on toothbrushing. Dietary measures do not seem to be of similar importance to them. The increasing self-perceived SES of the family and the education level of the mother have a significantly positive effect on the caries-preventive attitudes of the parents. Based on the study results, the message to the public health sector in the Czech Republic should include the need to highlight the importance of a non-cariogenic diet and the role of fluorides in caries prevention.

A total diet study (TDS) is a public health tool for determination of population dietary exposure to chemicals across the entire diet. TDSs have been performed in several countries but the comparability of data produced is limited. Harmonisation of the TDS methodology is therefore desirable and the development of comparable TDS food lists is considered essential to achieve the consistency between countries. The aim of this study is to develop and test the feasibility of a method for establishing harmonised TDS food and sample lists in five European countries with different consumption patterns (Czech Republic, Finland, Germany, Iceland and Portugal). The food lists were intended to be applicable for exposure assessment of wide range of chemical substances in adults (18-64 years) and the elderly (65-74 years). Food consumption data from recent dietary surveys measured on individuals served as the basis for this work. Since the national data from these five countries were not comparable, all foods were linked to the EFSA FoodEx2 classification and description system. The selection of foods for TDS was based on the weight of food consumed and was carried out separately for each FoodEx2 level 1 food group. Individual food approach was respected as much as possible when the TDS samples were defined. TDS food lists developed with this approach represented 94.7-98.7% of the national total diet weights. The overall number of TDS samples varied from 128 in Finland to 246 in Germany. The suggested method was successfully implemented in all five countries. Mapping of data to the EFSA FoodEx2 coding system was recognised as a crucial step in harmonisation of the developed TDS food lists.

Effect of site level environmental variables, spatial autocorrelation and sampling intensity on arthropod communities in an ancient temperate lowland woodland area.

PubMed

Horak, Jakub

2013-01-01

The interaction of arthropods with the environment and the management of their populations is a focus of the ecological agenda. Spatial autocorrelation and under-sampling may generate bias and, when they are ignored, it is hard to determine if results can in any way be trusted. Arthropod communities were studied during two seasons and using two methods: window and panel traps, in an area of ancient temperate lowland woodland of Zebracka (Czech Republic). The composition of arthropod communities was studied focusing on four site level variables (canopy openness, diameter in the breast height and height of tree, and water distance) and finally analysed using two approaches: with and without effects of spatial autocorrelation. I found that the proportion of variance explained by space cannot be ignored (≈20% in both years). Potential bias in analyses of the response of arthropods to site level variables without including spatial co-variables is well illustrated by redundancy analyses. Inclusion of space led to more accurate results, as water distance and tree diameter were significant, showing approximately the same ratio of explained variance and direction in both seasons. Results without spatial co-variables were much more disordered and were difficult to explain. This study showed that neglecting the effects of spatial autocorrelation could lead to wrong conclusions in site level studies and, furthermore, that inclusion of space may lead to more accurate and unambiguous outcomes. Rarefactions showed that lower sampling intensity, when appropriately designed, can produce sufficient results without exploitation of the environment.

2018-04-20

Following the identification of severe fever with thrombocytopenia syndrome and Heartland viruses, the interest on tick-borne phleboviruses has increased rapidly. Uukuniemi virus has been proposed as a model for tick-borne phleboviruses. However, the number of available sequences is limited. In the current study we performed whole-genome sequencing on two Uukuniemi viral strains isolated in 2000 and 2004 from Ixodes ricinus ticks in the Czech Republic. Both strains cluster together with Potepli63 strain isolated in the country in 1963. Although the Czech strains were isolated many years apart, a high identity was seen at the nucleotide and amino acid levels, suggesting that UUKV has a relatively stable genome.

Three classes of DNA damage were assessed in human placentas collected (in 2000-4) from 51 women living in the Teplice region of the Czech Republic, a mining area considered to have some of the worst environmental pollution in Europe in the 1980s. Polycyclic aromatic hydrocarbon (PAH)-DNA adducts were localized and semiquantified using immunohistochemistry (IHC) and the Automated Cellular Imaging System (ACIS). More generalized DNA damage was measured both by 32P-postlabeling and by abasic (AB) site analysis. Placenta stained with antiserum elicited against DNA modified with r7, t8-dihydroxy-t-9, 10-oxy-7,8,9,10-tetrahydro-benzo[a]pyrene (BPDE) revealed PAH-DNA adduct localization in nuclei of the cytotrophoblast (CT) cells and syncytiotrophoblast (ST) knots lining the chorionic villi. The highest levels of DNA damage, 49–312 PAH-DNA adducts/108 nucleotides, were found by IHC/ACIS in 14 immediately-fixed placenta samples. An additional 37 placenta samples were stored frozen before fixation and embedding, and because PAH-DNA adducts were largely undetectable in these samples, freezing was implicated in the loss of IHC signal. The same placentas (n = 37) contained 1.7 – 8.6 stable/bulky DNA adducts/108 nucleotides and 0.6 – 47.2 AB sites/105 nucleotides. For all methods there was no correlation among types of DNA damage and no difference in extent of DNA damage between smokers and non-smokers. Therefore, the data show that DNA from placentas obtained in Teplice contained multiple types of DNA damage, which likely arose from various environmental exposures. In addition, PAH-DNA adducts were present at high concentrations in the CT cells and ST knots of the chorionic villi. PMID:20839217

This article is focused on the mechanical testing of cement-based samples containing a micronized waste marble powder used as replacement of standard binders. Tested materials consisted of cement CEM I 42.5 R (Radotín, Czech Republic) and three different amounts of the marbles (25, 50 and 70 wt. %). Standard bending and compressive tests of the prismatic samples having dimensions equal to 40 × 40 × 160 mm were done in order to reveal an influence of marble amount on flexural and compressive strength, respectively. Moreover, the dynamic modulus of elasticity and dynamic shear modulus were examined and compared after 7 and 28 days of mixture curing.

Sunitrová, Ivana; Trník, Anton

2017-07-01

In this study the thermal expansion of ceramic samples made from natural zeolite is investigated. Samples are prepared from the two most commonly used materials in ceramic industry (kaolin and illite). The first material is Sedlec kaolin from Czech Republic, which contains more than 90 mass% of mineral kaolinite. The second one is an illitic clay from Tokaj area in Hungary, which contains about 80 mass% of mineral illite. Varying amount of the clay (0 % - 50 %) by a natural zeolite from Nižný Hrabovec (Slovak Republic), containing clinoptilolite as major mineral phase is replaced. The measurements are performed on cylindrical samples with a diameter 14 mm and a length about 35 mm by a horizontal push - rod dilatometer. Samples made from pure kaolin, illite and zeolite are also subjected to this analysis. The temperature regime consists from linear heating rate of 5 °C/min from 30 °C to 1100 °C. The results show that the relative shrinkage of ceramic samples increases with amount of zeolite in samples.

Food of non-animal origin is a major component of the human diet and has been considered to pose a low risk from the point of view of bacteriological safety. However, an increase in the number of outbreaks of illness caused by such pathogens and linked to the consumption of fresh fruit and vegetables have been reported from around the world recently. Salmonella spp., STEC (Shiga toxin producing Escherichia coli) and Listeria monocytogenes are among the most frequently identified agents. Additionally, the transmission of antibiotic resistant strains including also the methicillin resistant S. aureus (MRSA) to humans via the food chain is one of the greatest public health problems being confronted today. Therefore, we focused on the bacterial safety of fruit, vegetables and sprouts on sale in the Czech Republic. One strain (0.3%) of Salmonella Enteritidis phage type PT8, one strain (0.3%) of MRSA and 17 strains (5.0%) of L. monocytogenes were isolated from a total of 339 collected samples. The most problematic commodities were frozen fruit and vegetables (packed and unpacked) and fresh-cut vegetables. Our findings indicate deficiencies in hygiene practices during harvesting, processing and distribution of these commodities. Although sprouts and berries are the most likely to be contaminated by human pathogens, only two samples were positive for the presence of L. monocytogenes. Copyright © 2016 Elsevier Ltd.

This study presents a comparison of seasonal variation, gas-particle partitioning and particle-phase size distribution of organochlorine pesticides (OCPs) and current-use pesticides (CUPs) in air. Two years (2012/2013) of weekly air samples were collected at a background site in the Czech Republic using a high-volume air sampler. To study the particle-phase size distribution, air samples were also collected at an urban and rural site in the area of Brno, Czech Republic, using a cascade impactor separating atmospheric particulates according to six size fractions. The timing and frequencies of detection of CUPs related to their legal status, usage amounts and their environmental persistence, while OCPs were consistently detected throughout the year. Two different seasonal trends were noted: certain compounds had higher concentrations only during the growing season (April-September) and other compounds showed two peaks, first in the growing season and second in plowing season (October-November). In general, gas-particle partitioning of pesticides was governed by physicochemical properties, with higher vapor pressure leading to higher gas phase fractions, and associated seasonality in gas-particle partitioning was observed in nine pesticides. However, some anomalous partitioning was observed for fenpropimorph and chlorpyrifos suggesting the influence of current pesticide application on gas-particle distributions. Nine pesticides had highest particle phase concentrations on fine particles (< 0.95 μm) and four pesticides on coarser (> 1.5 μm) particles.

2016-08-30

Millions of people worldwide suffer from specific phobias. Almost any stimulus may trigger a phobic reaction, but snakes are among the most feared objects. Half of the population feel anxious about snakes and 2-3% meet the diagnostic criteria for snake phobia. Despite such a high ratio, only one instrument is commonly used, the Snake Questionnaire (SNAQ). The aim of this study was to develop a standardized Czech translation, describe its psychometric properties and analyze the distribution of snake fears. In a counter-balanced design 755 respondents were asked to complete the English and Czech SNAQ (first or last) with a 2-3 month delay; 300 of them completed both instruments. We found excellent test-retest reliability (0.94), although the total scores differed significantly when the English version was administered first. The mean score was 5.80 and Generalized Linear Models revealed significant effects of sex and field of study (women and people with no biology education scored higher than men and biologists). A cut-off point for snake phobia as derived from a previous study identified 2.6% of the subjects as phobic. Finally, the score distribution was similar to other countries supporting the view that fear of snakes is universal. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Cross-borehole flow analysis to characterize fracture connections in the Melechov Granite, Bohemian-Moravian Highland, Czech Republic

Paillet, Frederick L.; Williams, John H.; Urik, Joseph; Lukes, Joseph; Kobr, Miroslav; Mares, Stanislav

2012-01-01

Application of the cross-borehole flow method, in which short pumping cycles in one borehole are used to induce time-transient flow in another borehole, demonstrated that a simple hydraulic model can characterize the fracture connections in the bedrock mass between the two boreholes. The analysis determines the properties of fracture connections rather than those of individual fractures intersecting a single borehole; the model contains a limited number of adjustable parameters so that any correlation between measured and simulated flow test data is significant. The test was conducted in two 200-m deep boreholes spaced 21 m apart in the Melechov Granite in the Bohemian-Moravian Highland, Czech Republic. Transient flow was measured at depth stations between the identified transmissive fractures in one of the boreholes during short-term pumping and recovery periods in the other borehole. Simulated flows, based on simple model geometries, closely matched the measured flows. The relative transmissivity and storage of the inferred fracture connections were corroborated by tracer testing. The results demonstrate that it is possible to assess the properties of a fracture flow network despite being restricted to making measurements in boreholes in which a local population of discrete fractures regulates the hydraulic communication with the larger-scale aquifer system.

Constitutional limits to the financing of health care in the Czech Republic and in selected European countries.

PubMed

Prudil, Lukás

2003-01-01

The aim of this paper is to describe the constitutional limits to the financing of health care and especially of public health insurance in the Czech Republic. It describes the current situation in the financing of health care on the basis of the Czech constitutional order as it has been interpreted by the Constitutional Court. Finally it presents an overview of the incorporation of the right to health into the constitutional documents of several European countries with the stress on the right to receive health care "free of charge". It is not typical within the European region to specify in constitutional acts to what extent it is giving the right to health care free-of-charge or more precisely to what extent and for what groups health care is paid for by persons other than by the citizens (patients). The Czech Republic is one of the exceptional cases in which the basic right to health care free-of-charge on the basis of public insurance is given directly by the Constitution.

Czech lesbian activism: gay and lesbian parental rights as a challenge to patriarchal marriage.

PubMed

Fojtová, Simona

2011-01-01

In their advocacy for the legal recognition of same-sex relationships during the 1990s, prominent Czech gay rights activists focused only on issues of sexuality and did not question the essentialist understanding of gender, especially in parenting. Consequently, even though the Czech Republic legalized registered partnerships for gays and lesbians in 2006, legal barriers now exist regarding parental rights for same-sex couples, who are prohibited from adopting children and accessing reproductive technology once they register with the state. This article examines a rising, new wave of Czech lesbian activism that has focused on gaining legal parental rights for registered same-sex couples. While lesbian activists were disempowered in terms of their public visibility as well as political involvement during the 1990s, the recent growing prominence of lesbian groups has been enabled by their stronger political focus and organizational coherence. Analyzing the lesbian activists' strategies, I show not only how lesbian activism can advance the public debate about traditional gender roles, but also how lesbian activism can strengthen the critique of the ideology of marriage.

Authors deal with practice of nursing care provided to Muslim clients in the Czech Republic. They use the explorative research design. By means of analyses of 21 semi-structured interviews with important social actors in the area of health care (spa resorts and hospitals). The study shows that Muslims are not homogeneous in their behaviour in the field of health care. In the spa environment, three interpretation perspectives can be found: the economic interpretation of a Muslim as the source of income of the Czech spa industry, which faces economic problems, the cultural interpretation developed within the spas (the experience capital of the staff and other clients), and the (a) cultural interpretation of Muslims and Islam brought to spas from the outside (the public opinion). However, in the area of hospitals, Muslims are not separated from the remaining categories of students; Muslim patients represent a small group of persons, and their treatment being conditioned by the distance or closeness of cultures, language skills, adaptation, and experiences with treatment in the Czech environment as perceived by the staff.

Women's partnered orgasm consistency is associated with greater duration of penile-vaginal intercourse but not of foreplay.

It has been asserted that women's likelihood or consistency of partnered orgasm (her orgasm as a result of sexual activities with a partner) is determined by duration of foreplay, but not by duration of penile-vaginal intercourse. The objective was to examine the extent to which women's likelihood or consistency of partnered orgasm is associated with duration of foreplay, duration of penile-vaginal intercourse, and age. In a representative sample of the Czech population, 2,360 women reported their consistency of orgasm with a partner (from "never" to "almost every time"), and estimates of their typical durations of foreplay and of penile-vaginal intercourse. The association of consistency of partnered orgasm with typical durations of both foreplay and penile-vaginal intercourse. In univariate analyses, consistency of partnered orgasm was more associated with penile-vaginal intercourse duration than with foreplay duration (consistency also correlated negatively with age). In multivariate analysis, foreplay ceased to be a significant correlate of partnered orgasm consistency (the exclusion of respondents reporting a penile-vaginal intercourse duration of 1 minute or less did not alter the results). When both sexual activity categories are examined in tandem on a population level, women's likelihood or consistency of partnered orgasm is associated with penile-vaginal intercourse duration, but not with foreplay duration. In contrast to the assumptions of many sex therapists and educators, more attention should be given to improve the quality and duration of penile-vaginal intercourse rather than foreplay.

Definite evidence has been established, that coronary patients benefit from appropriate secondary prevention measures, as recommended by the European and National Guidelines. EuroAspire I (1995) and EuroAspire II (1999) were surveys aimed to evaluate the state of the implementation of guidelines into the every-day medical practice in several European countries, including Czech Republic. We wondered to what extent the practice in secondary prevention of Czech physicians, since the guidelines were published, changed during 5 years, to pursue the targets. We compared two surveys, undertaken in the same geographical areas of the Czech Republic. Consecutive patients, males and females, less than 71 years of age were indentified following acute coronary event or revascularisation procedure and were interviewed and examined at least 6 months after hospitalization. The Czech surveys included 331 patients in EuroAspire I and 410 in EuroAspire II. In EuroAspire II, the total number of smokers decreased in males, but increased in females. The patients were more obese, had higher glucose levels as well, while blood pressure, total and LDL cholesterol and triacylglycerols were lower, than in EuroAspire I. Corresponding changes also occurred in the prevalence of hypertension and hyperlipidaemias by definitions. There was a significant increase in the use of betablockers, ACE inhibitors and hypolipidemic drugs, mainly statins. In conclusion, in spite that the compliance with the recommendations for secondary prevention improved, achievement of targets remained rather unsatisfactory, likewise in other European countries.

Familial hypercholesterolemia (FH) is the most frequent autosomal dominant hereditary disease which is characterized by a decreased LDL-cholesterol catabolism and early clinical manifestation of atherosclerosis affecting blood vessels. The MedPed (Make early diagnosis to Prevent early deaths) project aims to diagnose patients with FH as early as possible, so that they can profit the most from a therapy started in a timely manner and avoid premature cardiovascular events. Currently, as of 31 October 2016, the Czech national database keeps records of 6 947 patients with FH from 5 223 families. Considering the prevalence of FH equalling 1 : 250, this represents 17.4 % of the overall expected number of patients with FH in the Czech Republic. Determining the mutation responsible for FH, now using a next generation sequencing technology in the Czech Republic, brings with it higher diagnostic accuracy, better cooperation of patients and in particular facilitation of cascade screening in families. Although we are among the most successful countries in the world with regard to FH detection, the majority of patients are still undiagnosed. Moreover, as it turns out, most FH patients do not reach the target values with the current therapeutic possibilities. In this regard the newly approved hypolipidemic drugs, PCSK9 inhibitors, to be hopefully available also in the Czech Republic in the near future for chosen patients with FH at high risk, hold great promise.Key words: cascade screening - familial hypercholesterolemia - LDL-cholesterol - MedPed.

Background The purchase of dietary supplements (DS) via the Internet is increasing worldwide as well as in the Czech Republic. Objective The aim of the study is to evaluate the quality of information on DS available on the Internet. Setting Czech websites related to dietary supplements. Methods A cross-sectional study was carried out involving the analysis of information placed on the websites related to the 100 top-selling DS in the Czech Republic in 2014, according to IMS Health data. Main outcome measure The following criteria were evaluated: contact for the manufacturer, recommended dosage, information on active substances as well as overall composition, permitted health claims, % of the daily reference intake value (DRIV) for vitamins and minerals, link for online counseling, pregnancy/breastfeeding, allergy information, contraindications, adverse reactions, and supplement-drug interactions (some criteria were evaluated from both points of view). Results A total of 199 web domains and 850 websites were evaluated. From the regulatory point of view, all the criteria were fulfilled by 11.3% of websites. Almost 9% of the websites reported information referring to the treatment, cure, or prevention of a disease. From the clinical point of view, all the criteria were only met by one website. Conclusions The quality of information related to DS available on the Internet in the Czech Republic is quite low. The consumers should consult a specialist when using DS purchased online.

Pricing and reimbursement of pharmaceuticals in the Czech Republic and Sweden.

To describe and compare price regulation and reimbursement in the Czech Republic and Sweden. Legal documents, government reports, statutory information, annual reports and scientific articles were searched using the keywords: pharmaceutical market regulation, drug policy, drug pricing, drug reimbursement and patients' participation in costs concerning both countries. Approaches to regulation and regulatory steps concerning prices were compared between the countries. (i) Institutional responsibilities in pricing and reimbursement of pharmaceuticals; (ii) principles of patients' participation in costs on pharmaceuticals. Substantial differences were found in terms of pricing. In the Czech Republic, the Ministry of Finance sets maximal prices for pharmaceuticals whereas in Sweden there is a process of price regulation combined with reimbursement decisions taken by the Pharmaceutical Benefits Board. Together with a system of state-owned pharmacies, this ensures that drug prices in Sweden are fixed at the same level throughout the country. In the Czech Republic, prices may differ, since only maximal price levels are set. In both countries, decisions about reimbursement are taken at the national or state level whereas insurance funds or county councils are responsible for covering costs. The private share of pharmaceutical expenditures is substantially lower in the Czech Republic, even though there is no maximal level for patient's co-payment, as there is in Sweden. Differences in price setting and some other regulations of the pharmaceutical market were found. Both systems are designed to promote rational use of pharmaceuticals; and are based on social solidarity.

Low Frequencies of Autoimmunity-Associated PTPN22 Polymorphisms in MODY Patients, Including Those Transiently Expressing Islet Cell Autoantibodies.

The protein tyrosine phosphatase nonreceptor type 22 (PTPN22) gene encodes lymphoid tyrosine phosphatase (LYP), which is expressed primarily in lymphoid tissues. The functional but geographically highly variable PTPN22 single-nucleotide polymorphisms (SNPs), particularly c.1858C>T, contribute to the onset and progression of autoimmunity-associated diseases and facilitate the expression of disease-associated autoantibodies. In Central Europe, 17-25% of patients with monogenic diabetes (maturity-onset diabetes of the young, MODY) transiently express islet cell autoantibodies. We addressed the links between the functional and geographically variable PTPN22 SNPs with MODY manifestation and the expression of islet cell autoantibodies in 276 MODY patients who originated from four regions (the Czech Republic, Israel, Japan and Brazil). The frequency of PTPN22 polymorphisms in the MODY patients was similar to those in geographically matched healthy populations, with the exception of c.788G>A, the minor allele frequency of which was significantly elevated in the Czech hepatocyte nuclear factor 1-α (HNF1A) MODY patients [odds ratio (OR) 4.8, 95% confidence interval (CI) 2.2-10.7] and the Brazilian MODY patients (OR 8.4, 95% CI 1.8-39.1). A barely significant increase in the c.788G>A minor allele was also detected in the islet cell autoantibody-positive Czech MODY patients. However, c.788A behaves as a loss-of-function mutant in T cells, and thus protects against autoimmunity. MODY patients (including islet cell autoantibody-positive cases) do not display any increase in autoimmunity-associated PTPN22 alleles. The absence of autoimmunity-associated PTPN22 alleles was also demonstrated in latent autoimmune diabetes in adults, which suggests that the slow kinetics of the onset of autoantibodies is subject to a regulation that is different from that experienced in type 1 diabetes and other autoimmune disorders. © 2015 S.

Epidemiology of Tick-Borne Encephalitis in the Czech Republic 1970–2008

2012-01-01

Abstract This article presents major epidemiologic features of tick-borne encephalitis (TBE) in the Czech Republic, using data of laboratory-confirmed cases since 1970. A total of 17,053 cases of TBE were reported in the Czech Republic (population 10 million) in 1970–2008. The data show several important features. First, the pattern of TBE incidence changed over time. Until the end of the 1970s, TBE was characterized by periods of alternately higher and lower incidence (between 180 and 595 cases per year); the 1980s were a period of low incidence with minimum variability; since the beginning of the 1990s, there has been a steep rise in incidence, with marked year-to-year variation (e.g., 745 cases were registered in 1995, and a maximum of 1029 cases were registered in 2006). Second, the age distribution of TBE incidence has changed. Until the end of 1990s, incidence peaked among those 15–19 years of age, with a gradual decline with age. In the 2000s, however, TBE incidence has been rising in those aged 60–64 years, with a sharp decline in those older than 65 years. Third, the seasonal pattern of TBE has changed markedly over time. In the earlier period, incidence had a clear peak in July/August; since the 1990s, more cases have occurred in earlier and later months of the year. The proportion of cases occurring in April, May, October, and November increased from 9% in the 1970s to 23% in 2000–2008. Fourth, the geographical distribution of TBE also changed over time, with TBE increasingly occurring in the mountainous districts at higher altitudes. These changes in incidence patterns appear to be linked with changes in climatic and meteorological conditions. The link between climate change and TBE incidence is plausible, since TBE is a recreation-related infection associated with outdoor activities, and since climatic changes affect the life cycle of the vector.

The paper summarizes results of monitoring of (137)Cs activities in game species roaming in the woods over the territory of the Czech Republic for the time interval of 1986-2012. Geometric means and other statistical characteristics were estimated from the data sets on the assumption of log-normal distribution of the data from the time interval 2004-2012 where the character of data distribution had displayed no significant change. Geometric means (in Bq/kg) in meat were: wild boar 5.1, red deer 1.9, roe deer 0.77 and feathered game 0.14. The mean value in the less frequent game amounted to 0.36 Bq/kg. The geometrical standard deviation (GSD) widely varied from 1.6 to 21 for the studied species. Based on mass activity dependence on time, we assessed the effective and environmental half-lives of activity decline. For red deer and roe deer, the effective (137)Cs half-life was 2.9 and 3.2 years, and environmental half-life 3.2 and 3.6 years respectively. The effective half-life of (137)Cs in wild boar of 38 years was determined with large uncertainty and it shows constant influx of (137)Cs activity to the digestive tract of wild boars. A statistically significant season-based (137)Cs level was found in red deer and wild boar. Higher winter and spring activities of (137)Cs in wild boar are linked with decreasing access to naturally occurring food with lower (137)Cs content (chestnuts, acorns, and beech nuts), making boar grub around for ground-deposited food (often for mushrooms with higher activity). Higher winter activities of (137)Cs in red deer meat, most probably, are due to lower access to green diet in winter. The average annual committed effective dose for Czech population based on estimates of game species meat consumption between 2004 and 2012 was insignificant, only 0.03 μSv.

Impacts of the 2015 Heat Waves on Mortality in the Czech Republic-A Comparison with Previous Heat Waves.

2017-12-13

This study aimed to assess the impacts of heat waves during the summer of 2015 on mortality in the Czech Republic and to compare them with those of heat waves back to the previous record-breaking summer of 1994. We analyzed daily natural-cause mortality across the country's entire population. A mortality baseline was determined using generalized additive models adjusted for long-term trends, seasonal and weekly cycles, and identified heat waves. Mortality deviations from the baseline were calculated to quantify excess mortality during heat waves, defined as periods of at least three consecutive days with mean daily temperature higher than the 95th percentile of annual distribution. The summer of 2015 was record-breaking in the total duration of heat waves as well as their total heat load. Consequently, the impact of the major heat wave in 2015 on the increase in excess mortality relative to the baseline was greater than during the previous record-breaking heat wave in 1994 (265% vs. 240%). Excess mortality was comparable among the younger age group (0-64 years) and the elderly (65+ years) in the 1994 major heat wave while it was significantly larger among the elderly in 2015. The results suggest that the total heat load of a heat wave needs to be considered when assessing its impact on mortality, as the cumulative excess heat factor explains the magnitude of excess mortality during a heat wave better than other characteristics such as duration or average daily mean temperature during the heat wave. Comparison of the mortality impacts of the 2015 and 1994 major heat waves suggests that the recently reported decline in overall heat-related mortality in Central Europe has abated and simple extrapolation of the trend would lead to biased conclusions even for the near future. Further research is needed toward understanding the additional mitigation measures required to prevent heat-related mortality in the Czech Republic and elsewhere.

To characterize the epidemiological situation of pertussis in children under one year of age in the Czech Republic in 1997-2013. The study cohort consisted of children under one year of age with laboratory confirmed pertussis reported to the communicable disease system from 1997 to 2013. A total of 265 pertussis cases were reported in children under one year of age over the study period. Selected demographic data, need for hospitalization, and vaccination history were evaluated in the study cohort. Children under one year of age have shown a steady upward trend in reported cases of pertussis since the 1990s. The reported incidence of pertussis in this age group was the lowest in 1998 (1.1/100,000 population) and the highest in 2013 (31.3/100,000). In 1997-2013, 265 pertussis cases were reported in children under one year of age, 128 females and 137 males, to the communicable disease system in the Czech Republic. Most of these children, nearly 77%, developed pertussis within the first four months of life. Of the 265 children, 79% were not vaccinated before the onset of the disease and 21% were immunized with at least one dose of pertussis vaccine before developing the disease. As many as 75% of the children with pertussis needed hospitalization. Most of them, nearly 81%, were hospitalized with pertussis in the first four months of life and 90% of them in the first six months of life. In 1997-2013, an upward trend was observed in pertussis cases in children under one year of age. Most children developed the disease within the first four months of life while not vaccinated against pertussis. This fact unambiguously supports the "cocoon" strategy, i.e. vaccination of the closest contacts of the child, and a booster dose at 25 years of age. At the same time, a question arises whether to provide vaccination to pregnant women.

Cereal crop harvests reflect the weather patterns of the period immediately preceding them, and thus the dates at which they begin may be used as a source of proxy data on regional climate. Using systematic phenological observations in the Czech Lands (now known as the Czech Republic) after 1848, together with exploration of further surviving documentary evidence (chronicles, diaries, financial accounts etc.), it has proved possible to create series of winter wheat harvest dates for the period 1501-2008. Employing linear regression, the harvesting dates of the main cereal species (wheat, rye, barley, oats) were first converted to winter wheat harvest days and then normalised to the same altitude above sea level. The next step consisted of using series of winter wheat harvest dates to reconstruct mean March-June temperatures in the Czech Lands, applying standard palaeoclimatological methods. Series reconstructed by linear regression explain 70% of temperature variability. A profound cold period corresponding with late winter wheat harvests was noted between 1659 and 1705. In contrast, warm periods (i.e. early winter wheat harvests) were found for the periods of 1517-1542, 1788-1834 and 1946-2008. The period after 1951 is the warmest of all throughout the entire 1501-2008 period. Comparisons with other European temperature reconstructions derived from documentary sources (including grape harvest dates), tree-ring and instrumental data reveal generally close agreement, with significant correlations. Lower correlations around A.D. 1650 and 1750 may be partly related to deterioration of socio-economic conditions in the Czech Lands resulting from prolonged wars. The results obtained demonstrate that it is possible to use widely-available cereal harvest data for climate analysis and also that such data constitute an independent proxy data series for the region of Central Europe crucial to further studies of the potential impact of climatic variability and climate change on agriculture.

The aim of this paper is to specify the cost of treatment and care for people with Alzheimer's disease (AD) in the Czech Republic and also with a view to the future. Data availability is evaluated as well as the quality of cost comparison with other developed countries. Data for the Czech Republic will include data from the health insurance company regarding medicines and treatment, as well as a selected home caring for people with dementia and, ultimately, the Social Security Administration. The basic methods include an analysis of data from publicly available sources, direct interviews with the representatives of nursing homes caring for people with dementia and the representative of the Social Security Administration of the Czech Republic. Items will be specified within the category of direct costs. For the study, the indirect costs related to the loss of patient as well as caring person productivity are not considered. Costs for treatment and care are based from the data on 4162 patients, the costs of a bed from data on 391 beds in homes for the elderly. The average annual cost per patient with AD in the Czech Republic was calculated and came to the amount of 12,783 EUR. These items include outpatient care, inpatient care in a medical facility, inpatient care in homes and medications. In terms of share of these items on the direct costs, the largest item are services provided by special homes which contributes to the direct costs by 94 %, medications create 1 % and treatment (both outpatient and inpatient) 5 %. In the case of home care the total costs are lower at 4698 EUR. The Czech Republic as well as other developed countries are faced with the problem of unified accounting cost of people suffering from Alzheimer's disease. This then causes the calculation of the economic burden to be very difficult and indicative values.

Relationships between sudden weather changes in summer and mortality in the Czech Republic, 1986-2005

The study examines the relationship between sudden changes in weather conditions in summer, represented by (1) sudden air temperature changes, (2) sudden atmospheric pressure changes, and (3) passages of strong atmospheric fronts; and variations in daily mortality in the population of the Czech Republic. The events are selected from data covering 1986-2005 and compared with the database of daily excess all-cause mortality for the whole population and persons aged 70 years and above. Relative deviations of mortality, i.e., ratios of the excess mortality to the expected number of deaths, were averaged over the selected events for days D-2 (2 days before a change) up to D+7 (7 days after), and their statistical significance was tested by means of the Monte Carlo method. We find that the periods around weather changes are associated with pronounced patterns in mortality: a significant increase in mortality is found after large temperature increases and on days of large pressure drops; a decrease in mortality (partly due to a harvesting effect) occurs after large temperature drops, pressure increases, and passages of strong cold fronts. The relationship to variations in excess mortality is better expressed for sudden air temperature/pressure changes than for passages of atmospheric fronts. The mortality effects are usually more pronounced in the age group 70 years and above. The impacts associated with large negative changes of pressure are statistically independent of the effects of temperature; the corresponding dummy variable is found to be a significant predictor in the ARIMA model for relative deviations of mortality. This suggests that sudden weather changes should be tested also in time series models for predicting excess mortality as they may enhance their performance.

Impacts of hot and cold temperature extremes on hospital admissions for cardiovascular diseases

2010-09-01

Elevated mortality associated with high ambient temperatures in summer represents one of the main impacts of weather extremes on human society. Increases in mortality during heat waves were examined in many European countries; much less is known about the effects of heat waves on morbidity, measured for example by the number of hospital admissions. Relatively less understood is also cold-related mortality and morbidity in winter, when the relationships between weather and human health are more complex, less direct, and confounded by other factors such as epidemics of influenza/acute respiratory infections. The present study examines links between hot and cold temperature extremes and daily hospital admissions for cardiovascular diseases in the population of the Czech Republic over 1994-2007. We make use of a recently completed database of all admissions for cardiovascular diseases to hospitals in the area of the Czech Republic since 1994, with a detailed classification of diseases and detailed information concerning each patient (in total 1,467,675 hospital admissions over 1994-2007). The main goals of the study are (i) to identify excess/deficit morbidity during and after periods of heat waves in summer and cold spells in winter, (ii) to compare the links for individual diseases (e.g. acute myocardial infarction, I21; angina pectoris, I20; cerebral infarction, I63; brain ischemia, I64) and to identify those diagnoses that are most closely linked to weather, (iii) to identify population groups most vulnerable to temperature extremes, and (iv) to compare the links to temperature extremes for morbidity and mortality. Periods when morbidity data were affected by epidemics of influenza and acute respiratory infections in winter were excluded from the analysis.

The aim of this work was to describe an impact of soil moisture on soil respiration. Study was performed on soil samples from morphologically diverse study site in loess region of Southern Moravia, Czech Republic. The original soil type is Haplic Chernozem, which was due to erosion changed into Regosol (steep parts) and Colluvial soil (base slope and the tributary valley). Soil samples were collected from topsoils at 5 points of the selected elevation transect and also from the parent material (loess). Grab soil samples, undisturbed soil samples (small - 100 cm3, and large - 713 cm3) and undisturbed soil blocks were taken. Basic soil properties were determined on grab soil samples. Small undisturbed soil samples were used to determine the soil water retention curves and the hydraulic conductivity functions using the multiple outflow tests in Tempe cells and a numerical inversion with HYDRUS 1-D. During experiments performed in greenhouse dry large undisturbed soil samples were wetted from below using a kaolin tank and cumulative water inflow due to capillary rise was measured. Simultaneously net CO2 exchange rate and net H2O exchange rate were measured using LCi-SD portable photosynthesis system with Soil Respiration Chamber. Numerical inversion of the measured cumulative capillary rise data using the HYDRUS-1D program was applied to modify selected soil hydraulic parameters for particular conditions and to simulate actual soil water distribution within each soil column in selected times. Undisturbed soil blocks were used to prepare thin soil sections to study soil-pore structure. Results for all soil samples showed that at the beginning of soil samples wetting the CO2 emission increased because of improving condition for microbes' activity. The maximum values were reached for soil column average soil water content between 0.10 and 0.15 cm3/cm3. Next CO2 emission decreased since the pore system starts filling by water (i.e. aggravated conditions for microbes, closing soil gas pathways etc.). In the case of H2O exchange rate, values increased with increasing soil water contents (up to 0.15-0.20 cm3/cm3) and then remained approximately constant.

We present a design of a nanometrology measuring setup which is a part of the national standard instrumentation for nanometrology operated by the Czech Metrology Institute (CMI) in Brno, Czech Republic. The system employs a full six-axis interferometric position measurement of the sample holder consisting of six independent interferometers. Here we report on description of alignment issues and accurate adjustment of orthogonality of the measuring axes. Consequently, suppression of cosine errors and reduction of sensitivity to Abbe offset is achieved through full control in all six degrees of freedom. Due to the geometric configuration including a wide basis of the two units measuring in y-direction and the three measuring in z-direction the angle resolution of the whole setup is minimize to tens of nanoradians. Moreover, the servo-control of all six degrees of freedom allows to keep guidance errors below 100 nrad. This small range system is based on a commercial nanopositioning stage driven by piezoelectric transducers with the range (200 × 200 × 10) μm. Thermally compensated miniature interferometric units with fiber-optic light delivery and integrated homodyne detection system were developed especially for this system and serve as sensors for othogonality alignment.

Hemolytic disease in the newborn with its typical signs and poor prognosis has been known for centuries. Historically it can be divided into three pathological states which are fetal hydrops (hydrops fetus universalis), neonatal jaundice (icterus neonati gravis familiaris) and fetal anemia (anemia neonati). Almost 70 reports with quite accurate descriptions were found up to the end of 19th century. The patho physiological basis of the condition began to be studied at the beginning of the last century and the development of our knowledge is an example of the cooperation between pathologists, pediatricians, hematologists and later, obstetricians, immunologists and geneticists. Despite all the advances in this field it remains a serious disease up to this time. It is not managed successfully in all cases and despite successful immunological prophylaxis there are cases when we need to administer intrauterine transfusion based on the information received by dopplerometric measurement of arteria cerebri perfusion and fetal blood sampling. Review of lover cited literature. The history of the hemolytic disease in the newborn, its condition and approaches to it has not been recently compiled in the Czech Republic.

Participation in organized activities is related with a range of positive outcomes, but the way such participation is measured has not been scrutinized. Test-retest reliability as an important indicator of a scale's reliability has been assessed rarely and for "The scale of participation in organized activities" lacks completely. This test-retest study is based on the Health Behaviour in School-aged Children study and is consistent with its methodology. We obtained data from 353 Czech (51.9 % boys) and 227 Slovak (52.9 % boys) primary school pupils, grades five and nine, who participated in this study in 2013. We used Cohen's kappa statistic and single measures of the intraclass correlation coefficient to estimate the test-retest reliability of all selected items in the sample, stratified by gender, age and country. We mostly observed a large correlation between the test and retest in all of the examined variables (κ ranged from 0.46 to 0.68). Test-retest reliability of the sum score of individual items showed substantial agreement (ICC = 0.64). The scale of participation in organized activities has an acceptable level of agreement, indicating good reliability.
