Environmental samples (n = 254) were collected at regular intervals from 1994 to 1999 on three swine farms in the area of the district town Hodonín, Czech Republic. The samples of feed mixtures (n = 85), barn dust sediments (n = 44), and muscular (n = 42), hepatic (n = 41), and renal (n = 42) tissues of feeder pigs were analysed for the concentrations of mercury, cadmium and lead. The concentrations of mercury showed decreasing tendencies in animal tissue samples (1994–1996). Compared with the mean for the Czech Republic, the concentration of mercury was markedly higher in liver and kidney samples (0.064 mg/kg and 0.114 mg/kg, respectively) collected in 1998, the concentration of cadmium was moderately higher in feed, muscle, liver, and kidney samples collected in 1996–1998. Statutory limits were exceeded in two liver and two kidney samples and one feed sample only. The concentration of lead in muscle, kidney, and feed samples (1994–1996) and barn dust samples (1996–1998) showed also a decreasing tendency. However, the limit was exceeded in 16 muscle samples (0.11 to 0.23 mg/kg) collected in 1994–1999 and two kidney samples collected in 1996 (0.74 mg/kg) and 1999 (0.77 mg/kg). Heavy metals present in dust sediments apparently did not contribute significantly to their content in animal tissue. While the health risk resulting from the contents of mercury and cadmium can be classified as moderate, the contents of lead must be regarded as markedly more dangerous.

AbstractBackground:We investigated time trends in age, gender, growth hormone (GH) dose and height standard deviation score (SDS) in children with GH deficiency (GHD), born small for gestational age (SGA) or with Turner syndrome (TS) starting GH treatment.Methods:Data were obtained from children enrolled in the NordiNet®International Outcome Study (IOS) between 2006 and 2015 in the Czech Republic, France, Germany, Serbia and Montenegro (all indications), and Switzerland and the UK (GHD only). Trends were analyzed by linear regression. Patients were divided by age into early-, medium- or late-start groups in three different time periods.Results:Approximately one-third of children starting treatment for GHD were girls, with no apparent increase in proportion over time. The mean baseline age for starting treatment decreased significantly (p<0.001) for both GHD and SGA in the Czech Republic and Germany. In the other countries studied, over 40% of children started treatment for GHD and SGA late (girls >10, boys >11 years) between 2013 and 2015. The mean baseline GH doses were largely within recommended ranges for GHD and SGA, but below the lowest recommended starting dose for TS in almost every year since 2011 except in France.Conclusions:Approximately one-third of children starting treatment for GHD were girls. Between 2013 and 2015, more than 40% of children started treatment for GHD and SGA late except in Germany and the Czech Republic. TS patients received below-recommended doses. These results highlight the need for earlier identification of short stature in children, particularly girls, and for dose optimization in TS.

The black walnut (Juglans nigra L.), an introduced species into the Czech Republic, is planted for its production of valuable timber. A systematic study of the black walnut growth rate at different localities and consequently the creation of standard volume tables under Central European conditions therefore appear to be of high relevance. The aim of our study was to reveal the black walnut growth pattern in its pure stands in two riparian forests along the Morava and Svratka River (Str&aacute;žnice locality and Židlochovice locality, respectively). To describe and to compare relationships among diameter at breast height (dbh), tree height and age, we used a forest management plan and measured 573 and 670 trees in pure sample stands at Str&aacute;žnice and Židlochovice, respectively. We found out that the measured mean DBH and mean height were consistently higher in Str&aacute;žnice, however the relationships of DBH to height, age to DBH, and age to height showed the same pattern at both localities. The mean heights of trees were 16.3, 24.1, 28.7, 31.9, and 34.5 m in 20, 40, 60, 80, and 100 year age classes and were consistently taller in comparison with other, mainly European, regions. Therefore our results suggest the high potential of black walnut in timber production in riparian forests in the Czech Republic, mainly in the South Moravian region.

Reduction of colony diameter using two DMI-fungicides and one strobilurine fungicide was evaluated in the <i>Septoria tritici</i> population. In an <i>in vitro</i> assay, 57 strains of <i>S. tritici</i> originating from different parts of the Czech Republic were grown on agar plates containing different concentrations of fungicides. The mean EC<sub>50</sub> values of strains were analysed for flusilazole (Capitain), metconazole (Caramba) and one strobilurine fungicide: azoxystrobin (Amistar). ED 50 values for metconazole were low. There were highly significant correlation in reaction of pathogen strains to metconazole and flusilazole. Some isolates showed significant higher level of resistance to azoxystrobin. The data will be used in a continuing survey of resistance development in the <i>S. tritici</i> population originating from the territory of the Czech Republic.

In 2014, 18 hospitals in the Czech Republic participated in a survey of the incidence of Clostridium difficile infections (CDI) in the country. The mean CDI incidence was 6.1 (standard deviation (SD):7.2) cases per 10,000 patient bed-days and 37.8 cases (SD: 41.4) per 10,000 admissions. The mean CDI testing frequency was 39.5 tests (SD: 25.4) per 10,000 patient bed-days and 255.8 tests (SD: 164.0) per 10,000 admissions. A total of 774 C. difficile isolates were investigated, of which 225 (29%) belonged to PCR ribotype 176, and 184 isolates (24%) belonged to PCR ribotype 001. Multilocus variable-number tandem repeat analysis (MLVA) revealed 27 clonal complexes formed by 84% (190/225) of PCR ribotype 176 isolates, and 14 clonal complexes formed by 77% (141/184) of PCR ribotype 001 isolates. Clonal clusters of PCR ribotypes 176 and 001 were observed in 11 and 7 hospitals, respectively. Our data demonstrate the spread of two C. difficile PCR ribotypes within 18 hospitals in the Czech Republic, stressing the importance of standardising CDI testing protocols and implementing mandatory CDI surveillance in the country.

&nbsp;Based on yield tables for oak high forest and oak coppice (both first site class) and using assortment tables and assortment prices in the Czech Republic in 2009, a set of variants of conversion of high forest to coppice was simulated. Average annual cut and average gross value of annual cut of such conversions were compared with those of well-established (in terms of the age structure balance) variants of coppice and high forest. Under the existing ratio of assortment prices, established coppice does not reach the gross value yield of high forest. No variant of simulated conversions was more financially profitable than the initial high forest. Furthermore, we found out that a +16.8% increase of the current fuel wood price would counterbalance the mean annual increment of gross value of the best coppice and the worst oak high forest variant. On the other hand, a +164.7% fuel wood price increase would be necessary to counterbalance the mean annual increment of gross value of the worst coppice and the best high forest variants. &nbsp;

&nbsp;Twenty-one standard apple cultivars bred in Holovousy and registered in the Czech Republic during 1994&ndash;2011 were included in a comparative study. Their tree parameters and yields were evaluated from 2004 till 2011 in a comparison to cvs Golden Delicious and Jonagold within experimental orchards planted on M 9 rootstock using a tree spacing of 4 &times; 1 m. The cultivars mutually differed in the mean term of flowering starting up to 6 days. The harvest time of 5 summer cultivars covered the harvest season from July 14 till the end of August. The remaining cultivars were storable, and on average, their harvest started between the September 8(Nabella) and November 8 (Rubimeg). Cvs Resista, Selena and Vysočina were evaluated as totally resistant to scab and 5 other cultivars were distinguished by very low susceptibility to the disease. In the case of powdery mildew this desirable level of tolerance was observed on 7 cultivars. The most vigorous according to trunk cross-sectional area was cv. Mivine, whereas the weakest growing cv. Selena was 52% smaller in this parameter. Significant differences among cultivars were also found in the case of yield precocity. In total, the most productive in this study was cv. Clijo, with mean annual harvest equal to 44.3 t/ha. The lowest level of annual harvest (25.6 t/ha) gave cv. Selena, but its crop efficiency was one of the highest.

The baseline sensitivity of 55 isolates of Sclerotinia sclerotiorum, collected from oilseed rape in 6 regions of the Czech Republic, to selected fungicides was determined during the period 2013–2015. One single-component fungicide – Horizon (tebuconazole), and four multicomponent fungicides – Pictor (boscalid, dimoxystrobin), Efilor (boscalid, metconazole), Prosaro 250 EC (prothioconazole, tebuconazole), and Propulse (fluopyram, prothioconazole), were chosen as these are commonly used locally. The effect of each fungicide on the in vitro pathogen radial mycelial growth and EC<sub>50 </sub>values for the respective fungicides were determined. The following MIC values were estimated; for the fungicides Horizon 250 EW, Efilor, and Propulse the mean MIC values ranged between 0.125 and 0.250 µl/ml, for Prosaro 250 EC ranged between 0.0625 and 0.125 µl/ml, and for Pictor ranged from 0.00781 to 0.01562 µl/ml. No strains of S. sclerotiorum resistant to the tested fungicides were detected and the growth of all isolates was fully inhibited at concentrations corresponding to their registered dose rates. The highest fungicidal efficacy on the collected S. sclerotiorum isolates was recorded for Pictor, followed by Prosaro 250 with an EC<sub>50</sub> value 0.05856 µl/ml and then the remaining fungicides Propulse, Efilor, and Horizon 250 EW (EC<sub>50</sub> values 0.07277, 0.07221, and 0.08519 µl/ml, respectively).
