    Opis:
    BackgroundCancer risk (especially as regards lung cancer) in black-coal miners is mainly analyzed on the basis of mortality. The risk calculated based on mortality may differ from the values based on incidence. The aim of the study was to compare cancer risk in black-coal miners with and without coal workers’ pneumoconiosis (CWP), based on data on mortality and the incidence of lung cancer in the Czech Republic in 1992–2013.Material and MethodsThe cohort without CWP was composed of 6687 miners, and the cohort with CWP of 3476 miners. Information on the incidence of lung cancer was obtained from the Czech National Oncological Register (NOR), and information on mortality from the National Population Register. The risk of lung cancer incidence was compared with the general male population in the Czech Republic using the standardized incidence ratio (SIR), and the risk of lung cancer mortality using the standardized mortality ratio (SMR), with the 95% CI.ResultsIn miners with CWP, a lower SMR value was found, SMR = 1.70 (95% CI: 1.41–2.04), compared with the SIR value, SIR = 2.01 (95% CI: 1.70–2.36). In miners without CWP, this was opposite, the value of SIR = 0.81 (95% CI: 0.69–0.94) was lower than the value of SMR = 0.83 (95% CI: 0.70–0.98). In miners without CWP, 17 cases of lung cancer (out of 176 cases in total) were not registered in NOR. In miners with CWP, the share of not registered cases was significantly lower (p = 0.018), and it was represented by 3% of not registered lung cancer cases, out of 156 cases with the diagnosis of lung cancer.ConclusionsIn spite of the difference between SIR and SMR, the results of both indicators were consistent with the resulting relationship between the lung cancer risk and CWP.

    Opis:
    Objective: The aim of the study was comparison of cancer incidence risk of lungs, stomach, colon, bladder and kidneys from ex-miners of black coal mines and the general male population of the Czech Republic. Materials and methods: The analysis was conducted in two cohorts of ex-miners according to the presence of coalworkers’ pneumoconiosis (CWP). The first cohort included the miners without CWP (N = 6705), and the second cohort included the miners who were compensated for CWP (N = 2158). Personal and occupational data was merged with the data in the National Population Register and the National Oncological Register for the period from 1992 to 2006. Cancer risk in miners in comparison to the general male population of the Czech Republic was evaluated by SIR (Standardized Incidence Ratio) and 95% confidence interval (CI). Results: About twice as high risk of lung cancer was found in miners with CWP (SIR = 2.21; 95% CI: 1.75–2.76). Lung cancer risk correlated with the severity of CWP (simple CWP SIR=1.96; 95% CI: 1.48–2.56, progressive massive fibrosis SIR = 4.29; 95% CI: 2.09–7.87). No increased risk of lung cancer was found in ex-miners without CWP. The risk of malignant neoplasm at the other selected sites was comparable with the risk in the general male population of the Czech Republic. Conclusions: This study found increased lung cancer risk in coal miners with CWP, but not in those without CWP, comparing with the general population. These results served as the basis for the inclusion of lung cancer in association with CWP into a new Czech list of occupational diseases.

    Opis:
    Objectives The aim of the study was to assess health status of regular and part-time mines rescue brigadesmen. Material and Methods A group of 685 mines rescue brigadesmen was examined within the preventive testing – a basic internal, biochemistry and anthropometric examination, physical fitness testing. Results The average age of the subjects was 41.96±7.18 years, the average exposure in mining was 20±8.1 years, out of that 11.95±7.85 years as mines rescue brigadesmen. Elevated levels of total serum cholesterol (T-CH) and low-density lipoprotein cholesterol (LDL-CH) were found in over 1/2 of the subjects. Systolic hypertension (systolic blood pressure (SBP) ≥ 140 mm Hg) was confirmed in 34%, overweight (body mass index (BMI) ≥ 25) in 62.3% and obesity (BMI ≥ 30) in 20.4% of the examined mines rescue brigadesmen. The metabolic syndrome was found in 15.2% of persons. The highest physical fitness was found in mines rescue brigadesmen and the lowest in mine officers. Limit values of maximum oxygen uptake ($\text{VO}_\text{2 max}$/kg) determined by the management of the mine rescue station were not reached by every 3rd of all mines rescue brigadesmen. Compared with the control group of the Czech and Slovak population, the rescuers are taller, have greater BMI, higher percentage of body fat in all age categories and proportionally to that they achieve a higher maximum minute oxygen uptake; however, in relative values per kg of body weight their physical fitness is practically the same as that of the controls. Conclusions The prevalence of risk factors of cardiovascular diseases and $\text{VO}_\text{2 max}$/kg in the group of the mines rescue brigadesmen is comparable with that in the general untrained Czech population.

    Opis:
    Background The work of members of rescue teams could be associated with very high physical and thermal loads. If not timely interrupted, any extreme labour-thermal load may lead to a failure of the body and fatal collapse. This risk may be significantly reduced by devices that monitor the response of the body during the intervention and inform rescuers about the need to interrupt the exposure when the critical value of the reference indicator is achieved. The aim of the study was to test the correlation between the data of the newly developed device for signaling the strain of rescuers and the indicators of physiological response of the body. Material and Methods The tests were performed on 2 physically fit fire fighters dressed in a protective rescue suit and using insulating breathing apparatus, over a wide range of heat load under a model load on a bicycle ergometer in a climatic chamber. Results The study provided a significant correlation between the body temperature measured in the ear canal and the temperature under the suit sensed by the tested device – the Safety Ambient Monitor (SAM) (R = 0.9007). The temperature under the suit also correlated with the temperature of the chest skin (R = 0.8928) and heart rate (R = 0.8613). Conclusions A statistically significant correlation was proven between the temperature sensed by the SAM and the body temperature. The technical solution of sensing the temperature under the suit using the verified SAM technology does not affect or limit fire fighters in their work and minimizes the possibility of damage to the sensor and signaling failures.
