INTRODUCTION Workers of pellet production facilities (WPPF) are exposed to high concentrations of wood dust and microbial pollutants. Such stimulation may lead to numerous allergic and toxic reactions, infections, and other non-specific syndromes. OBJECTIVE To check the influence of individual traits of workers and characteristic features / factors of their living and working environments on the probability of adverse outcomes' appearance. MATERIAL AND METHODS The questionnaire study assessing adverse health effects resulting from individual exposure was conducted among 28 workers of 10 Polish WPPF. The logistic regression (for dichotomous variables) was used to determine the appearance probability (given as odds ratio) of adverse symptoms or diseases. RESULTS AND CONCLUSIONS WPPF workers may have an increased risk of developing work-related adverse health outcomes. Both the individual traits and environmental exposure factors significantly influence the probability of their occurrence.The strain of tuberculous mycobacteria called in Poland.INTRODUCTION AND OBJECTIVE The problem of occupational biohazards is very important, especially in the field of agriculture and in human and veterinary medicine. The aim of the study was to determine the potential sources of infection in veterinary professionals with selected zoonotic agents, including .INTRODUCTION AND OBJECTIVE Obesity and overweight among teenagers and young adults pose serious problems for the Polish health care system. The aim of this study was to assess the relationships between the prevalence of overweight and obesity and the level of urbanization, consumption of selected food products and socio-economic development in the provinces in Poland. MATERIAL AND METHODS The material used in this study is based on data published by the Central Statistics Office (GUS) for population, components of the Human Development Index (HDI), urbanization level (URBI), average monthly consumption of selected food products per person, and the percentage of obese and overweight people in the Polish provinces. The prevalence of overweight and obesity in all 16 provinces was analysed in the context of the URBI, HDI, and the average monthly consumption of selected food products. RESULTS There was no a statistically significant correlation between the number of overweight and obesity cases and the levels of HDI and URBI. The negative correlations were found between the consumption of sugar and URBI (-0,710, p=0.002), bread and grain product consumption (-0.642; p=0.007) and fresh milk consumption (-0.594; p=0.015). Fish consumption correlated with URBI at a moderate level (0.550; p=0.027). The consumption of oils and fats strongly correlated with HDI (-0.788; p less then 0,001). In the group of overweight woman, a moderate negative correlation was noted (-0.511; p=0.043) in cheese and curd consumption. CONCLUSIONS The high level of economic development and urbanization have no direct impact on the prevalence of overweight and obesity in Poland. The results of the study indicate existing dependencies of the consumption of some of selected products with respect to the level of urbanization.INTRODUCTION Medical care in geriatrics has its own specificity, and in order to build a successful doctor-patient relationship it is important while studying medicine to learn some functioning aspects of this age group. OBJECTIVE The aim of this study is to explore and describe the role of emotional intelligence in the attitudes of medical students towards elderly patients, taking into account their the place of residence. The place of residence has an impact on social relations and socialization, which could effect with disparities in behaviour towards elderly patients. MATERIAL AND METHODS Medical University of Lublin students from rural (N=71; M=23.44 SD=1.80) and urban (N=87; M=23.34; SD=1.38) areas took part in the study.  https://www.selleckchem.com/products/nms-p937-nms1286937.html  Emotional Intelligence Questionnaire (INTE) and Attitude Towards Elderly Patients Questionnaire (ATEP) were used. RESULTS There are statistically significant differences between medical students from rural and urban areas in their attitude towards elderly patients (p=0.001), but no differences were observed between rural and urban residents in terms of emotional intelligence (general result, action factor and cognitive factor). Positive correlations were observed between action factor (r=0.322), cognitive factor (r=0.311) and general INTE result (r=0.358) and attitude towards elderly patients in the group of medical students from rural area. CONCLUSIONS Medical students from rural areas are characterized by a more positive attitude towards elderly patients than medical students from urban areas. The predictors of attitudes towards elderly patients are the cognitive factor of emotional intelligence and the place of residence of medical students. The results give the opportunity to design a well-developed programme of a geriatric course which could be matched to the personal predispositions of students.INTRODUCTION Lithium has been used in medicine for almost seventy years. Besides beneficial effects, its therapy may cause serious side-effects, with kidney and liver being the organs most vulnerable to its harmful influence. Therefore, research on protective agents against lithium toxicity has been continuing for some time. OBJECTIVE The aim of the present study is to evaluate the influence of additional selenium supplementation on lithium content, as well as homeostasis of the essential microelements iron, zinc, copper and manganese in kidney and liver of rats undergoing lithium exposure. MATERIAL AND METHODS The study was performed on 4 groups of male Wistar rats (6 animals each) treated with control - saline; Li-group - Li at doses of 2.7 mg Li/kg b.w. and of 0.5 mg Se/kg b.w., respectively, in the form of water solutions by stomach tube, once a day for 3 weeks. The content of the studied elements in the organ samples was determined using flame atomic absorption spectroscopy (FAAS). RESULTS Lithium administered alone caused a significant increase in its content in liver and kidney. Additional supplementation with selenium reversed these effects, and did not markedly affect other studied microelements compared to control. CONCLUSIONS The obtained results suggest that selenium could be regarded as an adjuvant into lithium therapy. However, considering the limitations of the present study (the short duration, using only one dose and form of selenium) the continuation of the research seems to be necessary to clarify the influence of selenium supplementation on basic microelements and lithium accumulation in organs during lithium exposure.
