RESUMO
We retrospectively analyzed of 211 frozen cerebrospinal fluid samples from immunocompetent persons in the Czech Republic and detected 6 Encephalitozoon cuniculi-positive samples. Microsporidiosis is generally underestimated and patients are not usually tested for microsporidia, but latent infection in immunodeficient and immunocompetent patients can cause serious complications if not detected and treated.

Total joint arthroplasty is a commonly used surgical procedure in orthopedics. Revision surgeries are required in >10% of patients mainly because of prosthetic joint infection caused by bacteria or aseptic implant loosening caused by chronic inflammation. Encephalitozoon cuniculi is a microsporidium, an obligate intracellular parasite, capable of exploiting migrating proinflammatory immune cells for dissemination within the host. We used molecular detection methods to evaluate the incidence of E. cuniculi among patients who had total hip or knee arthroplasty revision. Out of 49 patients, E. cuniculi genotypes I, II, or III were confirmed in joint samples from 3 men and 2 women who had implant loosening. Understanding the risks associated with the presence of microsporidia in periprosthetic joint infections is essential for proper management of arthroplasty. Furthermore, E. cuniculi should be considered a potential contributing cause of joint inflammation and arthrosis.

Enteroaggregative Escherichia coli (EAEC) strains including those of serogroup O111 are important causes of diarrhea in children. In the Czech Republic, no information is available on the etiological role of EAEC in pediatric diarrhea due to the lack of their targeted surveillance. To fill this gap, we determined the proportion of EAEC among E. coli O111 isolates from children with gastrointestinal disorders ≤ 2 years of age submitted to the National Reference Laboratory for E. coli and Shigella during 2013-2022. EAEC accounted for 177 of 384 (46.1â¯%) E. coli O111 isolates, being the second most frequent E. coli O111 pathotype. Most of them (75.7â¯%) were typical EAEC that carried aggR, usually with aaiC and aatA marker genes; the remaining 24.3â¯% were atypical EAEC that lacked aggR but carried aaiC and/or aatA. Whole genome sequencing of 11 typical and two atypical EAEC O111 strains demonstrated differences in serotypes, sequence types (ST), virulence gene profiles, and the core genomes between these two groups. Typical EAEC O111:H21/ST40 strains resembled by their virulence profiles including the presence of the aggregative adherence fimbriae V (AAF/V)-encoding cluster to such strains from other countries and clustered with them in the core genome multilocus sequence typing (cgMLST). Atypical EAEC O111:H12/ST10 strains lacked virulence genes of typical EAEC and differed from them in cgMLST. All tested EAEC O111 strains displayed stacked-brick aggregative adherence to human intestinal epithelial cells. The AAF/V-encoding cluster was located on a plasmid of 95,749â¯bp or 93,286â¯bp (pAAO111) which also carried aggR, aap, aar, sepA, and aat cluster. EAEC O111 strains were resistant to antibiotics, in particular to aminopenicillins and cephalosporins; 88.3â¯% produced AmpC ß-lactamase, and 4.1â¯% extended spectrum ß-lactamase. We conclude that EAEC are frequent among E. coli O111 strains isolated from children with gastrointestinal disorders in the Czech Republic. To reliably assess the etiological role of EAEC in pediatric diarrhea, a serotype-independent, PCR-based pathotype surveillance system needs to be implemented in the future.
RESUMO
PURPOSE: The purpose of this narrative review is to provide a comparison of several countries with different legislation and approaches to pharmacovigilance and to point out how these impact the number of adverse drug reactions (ADRs) that are reported to national competent authorities. METHODS: Legislative and statistical data regarding ADR reporting from various national competent authorities' websites, databases, and pharmacovigilance centers were used. In combination with the WHO pharmacovigilance quantitative indicator that was applied to evaluate the effectiveness of particular national pharmacovigilance systems in our scope. RESULTS: The study compared pharmacovigilance systems in six countries, focusing on ADR reporting from 2010 onwards. All countries required MAHs to report ADRs, while healthcare professionals' obligations varied. Per-capita ADR reports increased in all countries with available data, with the United States having a significantly higher reporting rate, possibly due to FDA campaigns. Despite starting later, China's per-capita reporting rate surpassed that of the Czech Republic and Japan. The study highlighted various measures taken by countries to enhance ADR reporting systems since the inception of their programs, contributing to the overall increase in reporting rates. CONCLUSIONS: ADR reporting is a global priority, with efforts made by different countries to strengthen their pharmacovigilance systems. Some success can be seen in gradually improving per-capita ADR reporting rates. The varying reporting rates and measures taken by each country may serve as a basis for further research and exchange of best practices to improve drug safety monitoring worldwide.

We use the synthetic control method to examine whether land-based gambling ban has an effect on crime in a given city. In a sample of four Czech cities where the ban was introduced, we show that these cities had roughly the same crime rate development in the years after the ban as the control cities without the ban, showing that there is no significant impact. As this is, to our knowledge, the first use of the synthetic control method in the context of gambling, the main contribution of this study lies in demonstrating the possibilities in its use. Employing this versatile method may improve the current situation where many gambling impact studies suffer from the absence of a control group or an identification strategy to confirm causal relationship. Last but not least, the results of this study make an important contribution to the debate on blanket measures in gambling regulation; although pathological gambling is linked to crime, banning this activity may not lead to the expected consequences.
RESUMO
AIM: Pinworm infection (known as enterobiasis or oxyuriasis) is one of the most common parasitic diseases globally and in the Czech Republic (CZ). The aim of this study is to analyse the available epidemiological data on the incidence of enterobiasis in the CZ from 2018-2022. METHODS: A descriptive analysis was done of enterobiasis (ICD-10 code B80) data reported to the electronic Infectious Disease Information System in the CZ from 2018 to 2022. Data processing and analysis were conducted using MS Excel 2016. Univariate and multivariate logistic regression analyses were performed to assess the association between the probability of hospitalization and categorical variables using STATA version 17. The ECDC Map Maker tool (EMMa) was used to create the incidence map. RESULTS: A total of 4,836 cases were reported during the study period, with an average annual incidence of 9.1 cases per 100,000 population. The highest number of cases occurred in 2019 (n = 1,174), and the lowest in 2021 (n = 780). The disease was most common in the paediatric population, with the highest average age-specific incidence rates observed in children aged 5-9 years (80.9 per 100,000 population) and 10-14 years (42.3 per 100,000 population). Of 14 administrative regions of the CZ, the Olomouc Region had the highest average annual incidence (28.7 per 100,000 population), while the Pilsen Region had the lowest (2.2 per 100,000 population). A total of 472 (9.8%) patients needed hospitalization, most of them in the categories 10-14 years (n = 200, 42.4%) and 5-9 years (n = 178, 38%). The highest hospitalization rate was found in the age group 75+ (36.4%). A significantly higher probability of hospitalization was found in the age groups 6-19 years and 65+ compared to working-age population with enterobiasis. A significantly lower probability of hospitalization was seen in 2020-2022 compared to 2019. No difference in the hospitalization rates was noted between genders. No enterobiasis-related death was reported during the study period. The disease occurs year-round. A decrease in reported cases was observed annually during the school summer holidays in July and August. Neither outbreak nor imported cases were noted. CONCLUSION: Given that enterobiasis is often asymptomatic, many cases are not captured in the surveillance system. The Czech prevalence data indicate that it mainly affects the paediatric population. Therefore, preventive measures and programs should primarily target children.

The article focuses on short-term (up to three years) and long-term (three years and beyond) reproductive intentions of women aged 18-49 living in the Czechia. Reproductive plans are predominantly formulated at the threshold of adulthood and only 11 % of women under 25 are unsure of their reproductive plans. In the short term, childbearing is planned with the greatest intensity at the ages of 25-29 and 30-34 (when 47 and 33 % of women plan to have a child, respectively), while for childless women the intensity of planning peaks slightly later, at the ages of 30-34 and 35-39 (planning rates of 54 and 50 %, respectively). Older women are not giving up their desire to pursue their reproductive plans. Despite the health risks associated with motherhood at an older age, 20 % of childless women aged 40-44 plan to have their first child in the next three years or later. In addition to age and the current number of children, short- and long-term reproductive plans also differ by women's education, with college graduates more likely to plan to have (another) child in the short and long term than women with less education. At the same time, short-term plans are influenced by women's partnership status, and in the case of long-term reproductive plans, the influence of perceptions of the long-term impact of the COVID-19 pandemic was observed.

This study explores the dynamics of coping strategies of Czech religious leaders during a peak of the COVID-19 pandemic. An interpretative phenomenological analysis reveals that mental health among pastors is closely linked to a need to maintain community and social contact, while physical health is related to limitations upon ritual elements. In all narratives, the lived experience of mental health in the form of prosocial behavior is significantly prioritized despite the possibility of spreading infection. The analysis also shows that maintaining the community is closely linked to risky behaviors, which positively affected group and individual well-being.

Bartonella schoenbuchensis causes bacteremia in ruminants and is transmitted by deer keds. Here, we report the complete genome sequences of three B. schoenbuchensis strains (L2, L19, and L24) recently isolated from deer keds (Lipoptena fortisetosa) in Czechia.
RESUMO
In the area of the Central and NW Bohemia, Czech Republic, the fossil wood is quite abundant, found in different states of preservation and present from Paleozoic (Pennsylvanian), through Mesozoic (Upper Cretaceous), to Cenozoic (upper Eocene to lower Miocene). So, this small area is ideal to demonstrate various aspects of the fossil wood analyses, including anatomy (unifacial vs. bifacial cambium, formation of tyloses and its significance, early vs. late wood, unambiguity of scientific terminology, stem vs. root wood), taphonomy (completeness of fossil record, influence of environment on mode of preservation, influence of preservation on wood anatomy and preservation potential, discrepancy between the record of wood and other organs), systematics (stem vs. crown group, wide concept of fossil wood genera, "mosaic" species, wood of extinct plants), and palaeoclimatic reconstruction (definition of "wood type," subjective vs. objective methods). The majority of the studied woods were thin-sectioned following the standard techniques and observed with a compound light microscope.

BACKGROUND AND OBJECTIVE: Intracerebral hemorrhage (ICH) is a serious medical condition with high mortality. However, factors leading to long-term mortality after ICH are largely unclear. The aim of this community-based study is to assess predictors of long-term mortality after spontaneous ICH. METHODS: We identified all patients admitted with spontaneous ICH to hospitals with a certified stroke unit in Brno, the second largest city in the Czech Republic (CR), in 2011, the year of the Czech Population and Housing Census. We reviewed their medical records for risk factors, radiographic parameters, and measures of post-stroke neurological deficit [National Institutes of Health Stroke Scale (NIHSS)]. Using the dates of death from the Czech National Mortality Register, we calculated mortality at 30 days, six months, one year, and three years after the ICH. Multivariate analysis with forward stepwise logistic regression was performed to determine independent predictors of mortality (p < 0.05). RESULTS: In 2011, 1086 patients with stroke were admitted to the four stroke-certified hospitals in Brno, CR. Of these, 134 had spontaneous ICH, with complete data available in 93 of them entering the final analysis. The mortality at 30 days, 6 months, 1 year, and 3 years post-ICH was 34%, 47%, 51%, and 63%, respectively. The mortality was highest in the first few days post-event, with 50% of patients dying in 255 days and average survival being 884 ± 90 days. Both NIHSS and modified ICH (MICH) score showed to be strong and reliable predictors of short- as well as long-term mortality; the risk of death post-ICH increased with older age and size of ICH. Other risk factors contributing to higher, primarily shorter-term mortality included history of cardiac failure, myocardial infarction, or atrial fibrillation. CONCLUSIONS: In our community-based study, we found that severity of neurological deficit at admission (NIHSS), combined with age and size of ICH, well predicted short- as well as long-term mortality after spontaneous ICH. A history of cardiac failure, myocardial infarction, or atrial fibrillation at presentation were also predictors of mortality, underscoring the need for optimal cardiac management in patients with ICH.
RESUMO
Many animals return to their home areas (i.e., 'homing') after translocation to sites further away. Such translocations have traditionally been used in behavioral ecology to understand the orientation and migration behavior of animals. The movement itself can then be followed by marking and recapturing animals or by tracking, for example, using GPS systems. Most detailed studies investigating this behavior have been conducted in smaller vertebrates (e.g., birds, amphibians, and mice), whereas information on larger mammals, such as red deer, is sparse. We conducted GPS-assisted translocation experiments with red deer at two sites in the Czech Republic. Individuals were translocated over a distance of approximately 11 km and their home journey was tracked. Circular statistics were used to test for significant homeward orientation at distances of 100, 500, 1000, and 5000 m from the release site. In addition, we applied Lavielle trajectory segmentation to identify the different phases of homing behavior. Thirty-one out of 35 translocations resulted in successful homing, with a median time of 4.75 days (range 1.23-100 days). Animals were significantly oriented towards home immediately after release and again when they came closer to home; however, they did not show a significant orientation at the distances in between. We were able to identify three homing phases, an initial 'exploratory phase', followed by a 'homing phase' which sometimes was again followed by an 'arrival phase'. The 'homing phase' was characterized by the straightest paths and fastest movements. However, the variation between translocation events was considerable. We showed good homing abilities of red deer after translocation. Our results demonstrate the feasibility of conducting experiments with environmental manipulations (e.g., to impede the use of sensory cues) close to the release site. The homing behavior of red deer is comparable to that of other species, and might represent general homing behavior patterns in animals. Follow-up studies should further dissect and investigate the drivers of the individual variations observed and try to identify the sensory cues used during homing.

This study focuses on the Skalicka Waterwork (SWW), a largely debated and media-covered water-related/flood-protection project in the Czech Republic. Relying primarily on stakeholder interviews, we traced back and reconstructed the project's development, including its key tipping points reflecting the changing societal preferences for particular measures, yet also the involvement of individual actors/stakeholders, and their differing views. The case eventually crystallized into the "dam versus polder" dispute; concerned by the repercussions for the local landscape, a joint initiative of NGOs, local activists, and politicians not only opposed the dam variant proposed by the state river basin administration but also succeeded in pushing through the alternative scheme of side dry polder. While in many ways specific (e.g. not entailing local resistance), the case exemplifies recent shifts (and respective struggles) within flood risk management, including the increasing importance attributed to complex, catchment-wide perspectives, joint local and scientific knowledge, participatory decision-making processes, or implementation of nature-based and hybrid solutions.
RESUMO
Knowledge of precipitation composition is important, among other things, to reveal changes in atmospheric chemistry. Here we present the long-term time trends in ratios of major ions in precipitation, namely nitrate to sulphate (NO3-/SO42-), ammonium to sulphate (NH4+/SO42-) and ammonium to nitrate (NH4+/NO3-). For this we explore the long-term time series recorded by the Czech Hydrometeorological Institute at eight monitoring sites situated in urban, rural and mountain regions of the Czech Republic between 1980 and 2020. To that end, we use innovative Bayesian inference with the Integrated Nested Laplace Approximation (INLA) computational method appropriate for investigating complicated large-scale data. Our results indicated: (i) increasing NO3-/SO42- ratio in precipitation over time and distinct seasonal behaviour with higher values in winter and lower values in summer, (ii) increasing NH4+/SO42- ratio in precipitation and distinct seasonal behaviour with higher values in summer and lower values in winter and (iii) relatively stable NH4+/NO3- ratio in precipitation with a mild recent increase and distinct seasonal behaviour with higher values in summer and lower values in winter. This behaviour pattern holds true for all the sites analysed, irrespective of their geographical position, altitude or environment. Though explored in detail rarely, the ion ratios are important to study as they reflect changes in atmospheric chemistry, mirroring changes in emissions and meteorology and suggesting changing impacts on ecosystems and the environment.

Background: Sarcocystis includes a global group of apicomplexan parasites with two-host life cycle frequently circulating in wildlife and domestic hosts, including humans. Two of the most important wild terrestrial carnivores acting as definitive hosts are the red fox and raccoon dog, due to their wide distribution in Europe and usage of wild and farmed animals as prey. This study was conducted to determine the prevalence of Sarcocystis in hunted red foxes and raccoon dogs from nine regions of the Czech Republic and to identify isolated sporocysts by molecular techniques. Methods: Approximately 5 g of the contents of large intestine from 200 animals (197 red foxes and three raccoon dogs) were examined by flotation centrifugation coprological method. Only samples of 50 red foxes and one raccoon dog positive to Sarcocystis spp. were used for the nested PCR (nPCR) method to amplify a fragment or partial sequence on the cox1 gene. Ten species-specific primer pairs for detection of Sarcocystis spp. using farm animals as intermediate hosts were utilized. Results: In total, 38.1% of the red foxes and 66.7% of the raccoon dogs were positive to Sarcocystis by light microscopy. The molecular characterization resulted in the identification of five species in the red fox: S. arieticanis, S. capracanis, S. cruzi, S. miescheriana, and S. tenella, while the PCR was negative for the sole raccoon dog. The highest intraspecific variation was found for S. miescheriana, while S. tenella was the most prevalent. Co-infections occurred in the large intestine of the red fox. No zoonotic species were found in our samples. Conclusion: This is the first study where the potential role of the red fox and raccoon dogs as spreaders of Sarcocystis to farm animals in the Czech Republic is shown. The use of species-specific primers provides a fast and easy method for screening multiple samples for a particular Sarcocystis species.
RESUMO
Recognizing the prevailing negative public opinion on mining, it is important to understand how firsthand encounters with mining activities might influence these perceptions. This study investigates how field trips to open pit coal mines and their reclamation sites in the Czech Republic affected the attitudes of 148 university students toward mining and mine reclamation. Using pre and post trip questionnaires, we observed significant changes: Students became less neutral about mining, saw it as a temporary disruptive activity, expressed reduced concern for social conflicts in mining areas, and showed increased support for the ecological restoration of post mining sites. These findings underscore the transformative impact of direct engagement with mine reclamation activities on shaping attitudes. Understanding these effects offers promise for positively shifting public perceptions of mining practices, emphasizing the potential for constructive changes in attitudes through field experiences with reclamation efforts in the Global North.
RESUMO
Background/Objectives: Molnupiravir (MOV), an oral antiviral COVID-19 treatment, was introduced in the Czech Republic in December 2021 for COVID-19 patients at a high risk of progression to severe disease requiring hospitalization. In this observational, retrospective study, we aimed to describe the characteristics and healthcare resource utilization in non-hospitalized, adult COVID-19 patients prescribed MOV in the Czech Republic between 1 January and 30 April 2022. Methods: A total of 621 patients were included and followed up with for 28 days. Results: The median age was 68.0 (20-99) years, 77.8% were overweight or obese, 14.1% smoked, and 85.7% were vaccinated. The overall cumulative incidence (95% CI) of all-cause hospitalization was 0.71 (0.37; 1.24) per 1000 person years or 1.9%, with similar rates across sexes, age groups, BMI category, multimorbidity category, polypharmacy category, and COVID-19 vaccination status. Among patients reported hospitalized, oxygen-based resources were not observed, and no deaths occurred. Conclusions: These data describe the characteristics and healthcare resource utilization in Czech MOV-treated patients whose clinical characteristics may put them at increased risk of severe disease.
RESUMO
Effective practices for supporting families with autistic children ensure a match between their needs and the expectations and competencies of the clinician. Applied behavior analysis (ABA) services are a common provision for serving autistic individuals. However, in regions where ABA is in its infancy, like the Czech Republic and North Macedonia, culturally relevant resources, regulations for practice, and standardized coursework are missing. In their absence, it is necessary to investigate the degree to which practitioners in the regions are meeting the behavioral needs of families. Assessing this match can set the stage for establishing more stable and effective services in the areas, as well as neighboring countries with similar historical foundations. Therefore, a survey was conducted to examine the perceptions of caregivers and trainers (those who self-identified as providing support to families with autistic children). A total of 233 caregivers and 204 trainers participated. Analysis of the survey responses verified the lack of behavioral knowledge on the part of the trainers, the apparent lack of access to ABA services for families in both regions, a potential misalignment between family needs and training targets, and the disparities between the two countries. The information evaluated here can be used to guide preservice training, dissemination efforts, and regulations surrounding behavioral practices.
RESUMO
This work evaluated the 25-year-long trends (1994-2018) in mercury (Hg) concentrations and fluxes in spruce litterfall at a forest research plot Nacetín (NAC) recovering from acidic deposition in the Ore Mountains, Czech Republic. The mean litterfall Hg deposition averaged 51 ± 18 µg m-2 year-1, which has been the highest litterfall Hg deposition reported up to date on the European continent. In contrast, the wet deposition (2017-2019) was an order of magnitude lower averaging at 2.5 ± 1.5 µg m-2 year-1. All the spruce litterfall components bark, twigs, needles, cones, and a mixture of unidentified fragments had elevated mean Hg concentrations relative to background sites averaging 256 ± 77, 234 ± 62, 119 ± 23, 95 ± 14, and 44 ± 15 µg kg-1, respectively. Elevated litterfall Hg deposition and concentrations were attributed to the nearby local Hg emission source-coal-fired power plants. Temporally, the decrease of Czech Hg emissions since the 1990s was reflected by the decreasing trend of Hg concentrations in litterfall bark, cones, and twigs, while in needles and other material, Hg increased but insignificantly. Total litterfall ratios of Hg/C, Hg/N, and Hg/S were lower than those in soil O horizons averaging at 0.23 ± 0.04, 9.5 ± 2.0, and 170 ± 37 µg g-1, respectively. Since the beginning of monitoring, total litterfall Hg/C exhibited no trend, Hg/N decreased, and Hg/S increased. The litterfall biomass deposition averaging at 469 ± 176 g m-2 year-1 increased through time resulting in an increased Hg litterfall deposition at NAC by 1.1 µg m-2 year-1 despite the decreases in Czech Hg emissions. Peaks of annual litterfall Hg deposition up to 96 µg m-2 year-1 at NAC during the 25 years of monitoring resulted from weather extremes such as rime-snow accumulation, wind gusts, droughts, and insect infestation, which all significantly affected the annual biomass deposition. Based on our observations, further increases in biomass and litterfall Hg deposition rates can be expected due to the onset of bark beetle infestation and the increasing number of droughts caused by climate change.
