RESUMO
BACKGROUND: A youths' neighborhood can play an important role in their physical, health, and emotional development. The prevalence of health risk behavior (HRB) in Czech youth such as smoking, drug and alcohol use is the highest in Europe. AIM: To analyze differences in HRB in youth residents within different types of Prague's neighborhoods in relation to the perception of the built environment, quality of their school and home environments. DATA AND METHODS: The data is based on the on-line survey among elementary school students aged between 14-15 years, which was administered in19 selected schools in Prague, during the months of October 2013 to March 2014. Respondents were asked their opinions on various issues related to their HRB, about their indoor and outdoor housing and school environments. The questionnaire was completed by 407 students. Factor analysis with a principal components extraction was applied to determine the underlying structure in the variables. A consequent field research was conducted to map the opportunity hot spots and critical places around the elementary schools. RESULTS: Binge drinking has been reported mainly by the students living in the housing estates with blocks of flats. The most frequent occurrence of daily smokers was found in the neighborhoods of old city apartment houses. High prevalence of risky marijuana use almost in all the surveyed types of neighborhoods. The respondents were more critical in their evaluation of school characteristics. The neighborhoods critically evaluated by the students as regards the school outdoor environments were the older apartment houses in the historical centre and inner city, the school indoor environment was worst assessed within the housing estate neighborhoods. CONCLUSIONS: Our results suggest that perceptions of problems in both residential and school environment are associated with HRB. This fact makes this issue of a serious importance also from the policy point of view. Mainly the school surroundings have to be better managed by the local authorities responsible for the public space. This research thus forms part of the Sophie project aiming to find the most efficient policies that would tackle with the inequalities in the health and quality of life.

We analysed the mortality trends (1986-2009) for all cancers combined and selected cancers in adult Romanians by three age groups (15-49, 50-69 and older than 70 years of age) in comparison with 11 other European countries. We extracted mortality data from the WHO database and grouped the countries into four regions: central and eastern Europe (Romania, Bulgaria, the Czech Republic, Hungary), Baltic countries (Estonia, Latvia and Lithuania), western and northern Europe (Austria, the Netherlands and Finland), and southern Europe (Croatia and Slovenia). Mortality rates were age-standardized against the standard European population. Significant changes in mortality trends were identified by Joinpoint regression and annual percentage changes (APCs) were calculated for periods with uniform trends. Cancer mortality in Romania was among the lowest in Europe in 1986, but was higher than most countries by 2009. Despite the declining mortality (APC) in younger Romanians for all cancers combined (men-1.5% from 1997, women-1.2% 1997-2004 and -3.8% 2004-2009), male lung cancer (-2.8% from 1997), female breast (-3.5% from 1999) and cervical (-5.4% from 2004) cancers, mortality has increased in middle-aged and elderly patients for most cancers analysed. The exception was declining stomach cancer mortality in most Romanians, except elderly men. For most cancers analysed, mortality declined in the Baltic countries in young and middle-aged patients, and in western and northern countries for all ages. Lung cancer mortality in women increased in all countries except Latvia. We urge immediate steps to reverse the alarming increase in cancer mortality among middle-aged and elderly Romanians.

BACKGROUND: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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 single cell gel electrophoresis assay (Comet assay) was selected as a biomarker of exposure to evaluate the impact of air pollution and lifestyle variables on hospitalized pregnancies in two districts with different air pollution levels in northern (Teplice) and southern (Prachatice) Bohemia. The hypothesis was that the DNA damage detected as single strand breaks would be generally higher in the district with higher air pollution levels. To undertake the study we enrolled 322 pregnancies in Teplice and 220 in Prachatice. Venous and cord blood were analysed using the original alkaline Comet assay procedure with lysis for 60 min, unwinding for 40 min and electrophoresis for 24 min. We also used a modified procedure in which unwinding was prolonged to 60 min and electrophoresis to 40 min. Peripheral white blood cells (WBC) were analysed using an image analyser system. When we analysed the results obtained for mothers and their children no differences were found between polluted and control districts. The prolongation of alkali unwinding and electrophoresis did not increase sensitivity of the assay. No effects of prematurity, ethnicity, smoking or GSTM1 polymorphism were observed for any of the Comet parameters. Multiple regression analyses were performed for the European population (n = 285). A statistical model was fitted to determine the relationship between the Comet parameters of mothers and their children. According to our results it seems that the Comet assay was not a particularly sensitive technique to determine the effects of environmental pollution at the DNA level if peripheral WBC are used.
