Inflammatory Bowel

Background: Several previous studies reported the negative impact of inflammatory bowel disease (IBD) on reproductive plans and fertility rate. The aim of our study was to investigate, for the first time, reproductive attitudes and fertility rate among Czech patients with IBD. Methods: Between March and August 2019, consecutive patients with IBD from 22 centres across the Czech Republic responded anonymously to a predefined questionnaire focused on the patients’ demographics, details of IBD and treatment, gynaecological/urological history, reproductive issues and patients’ knowledge on this topic. Results: The questionnaire was filled in by 798 patients (526 women; median age 34 years, 66% with Crohn’s disease). Of these, 58% of the females and 47.1% of the males already had ≥ 1 child (median 2 children). Women with IBD were significantly more worried about infertility (55.5% versus 22.4%), had more limitations in their sexual life (53.2% vs. 26.8%) and more frequently changed their earlier reproductive plans (27.6% versus 11.0%) than the males (p < 0.0001). The total fertility rate in female IBD patients was lower compared to the general population with 1.004 live births/IBD woman versus 1.69 live births/woman in the Czech population. The pattern of decreased fertility was observed in all age-specific categories. Of the childless patients, 14% of the women and 18.1% of the men were voluntarily childless. Approximately one-half of them indicated their IBD to be the primary cause. Conclusions: IBD seems to have a negative impact on patients’ reproductive plans and attitudes. The fertility rate in Czech IBD female patients was decreased compared to the general population in this study.

The basic principle of the economic reform of state forests of the CzechRepublic after 1990 was to separate ma&shy;nagement in forests from the implementation of production activities. A state enterprise Forests of the Czech Republic with its headquarters in Hradec Kr&aacute;lov&eacute; was charged to manage state forests. From the former 7 enterprises of state forests 78 joint-stock companies have been established that carry out silvicultural and logging activities in state forests and in forests of other owners under the conditions of competition environment and on the basis of contracts. The paper deals with the exact evaluation of partial and present results of the development of forestry economic reform, aimed at the study of the behaviour of transformed and privatised forest joint-stock companies.

This paper presents the results of a comparative analysis of relative tax burden of taxpayers (natural persons) with income from employment in the Czech Republic from 1993 to 2009. Single, childless taxpayers with tax residency in the Czech Republic were chosen to represent this category of taxpayers. The amount of the tax burden was conceived as the sum of natural person income tax and the social and health insurance premiums paid by the taxpayer (employee), constituting in its nature and character a tax equivalent. The amount of these legally imposed payments was set with respect to the state valid and effective as of December 31st of the relevant year, in case of the year 2009 with respect to the state as of June 30th. The results of the performed analysis prove gradual decrease in relative tax burden in the period of 1993–2009 for taxpayers of all income groups. However, the decrease cannot be characterized as uniform. The most marked decrease was identified with taxpayers in the upper income groups. The most significant change in the relative tax burden took effect in association with changes introduced in the Act on Income Taxes as of January 1st, 2008 when the progressive income tax of natural persons was replaced with a flat-rate tax and when changes were introduced to the concept of the partial income tax base calculations applicable to natural persons. The main contribution of this paper can be seen in the fact that the comparison encompasses the time interval covering the entire effective life of the Act on Income Taxes. It is also important that in view of the specified solution conditions, the relative tax burden values presented in the graphs can be understood as maximum values of the tax burden of taxpayers having income from employment.

Due to the new information and communication technologies, it is now possible to disconnect work from space and time and to take advantage of new ways of organizing work. One of the options is teleworking (TW), currently being implemented throughout Europe due to the condition created by the coronavirus pandemic. The aim of the paper is twofold: (i) to analyse a range of factors (size of the enterprise; foreign owner; written strategy; project-driven enterprise; disabilities; work-life balance; benefits, lack of workers, illness, lower cost, relax at work and comfort; renting space, IT level) influencing the duration of TW implementation in the small and medium-sized enterprises (SMEs) and (ii) to better define the differences between the SMEs where TW was introduced in a short time, and those introducing it over a longer period. Out of the total of 31 factors, six factors have been proved to have a different impact on the duration of TW implementation (TW implementation due to higher efficiency; monitoring is performed only according to the results; the managers see the disadvantage of TW in its possible misuse; the enterprises use internal TW regulations; the managers see the main advantage as higher operational flexibility; the introduction of TW, due to the balance of work and family life). All together, 44,000 SMEs in the Czech Republic were invited into the research. The data were collected from 1,018 enterprises, with 60% of the enterprises using TW actively; on average, these enterprises have been using it for seven years.

: The differences in Pb and Cd accumulation capabilities of <I>Salix miyabeana, S. viminalis, S. × blanda</I>, and <I>S. elbursensis</I> derived from willows planted in 1997 in coal-ash settling localities in the Krušné hory Mts.,the Czech Republic, were determined. Plantlets micropropagated by organogenesis were grown in sterile hydroponic media supplemented with 0.5mM Pb(NO<sub>3</sub>)<sub>2</sub> or 0.5mM Cd(NO<sub>3</sub>)<sub>2</sub>· 4H<sub>2</sub>O. The samples of roots and aboveground parts were collected after 48, 72, 96, and 168 h of cultivation. Generally, substantially higher concentrations of accumulated Pb and Cd were identified in roots than in aboveground parts of all willow clones, even if clonal differences in their accumulation were detected. The results sufficiently confirmed the clonal differences in the uptake and translocation of heavy metals in the above-mentioned willows.
