Background. Shift work may affect the occurrence and severity of hypertension, ischemic heart disease and dyslipidemia. The aim of the study was to assess the prevalence of ischemic heart disease, hypertension and dyslipidemia in shift workers. Material and methods. The study was carried out in the Bogdanka mine in Łęczna, Poland. The questionnaire, which was designed by the author of this work, was conducted among 700 shift workers who worked underground in the mine. Statistical analysis was performed using STATISTICA v. 7.1 (StatSoft, Poland) software. Results. Participants who believed that shift work may lead to deterioration of their health also believed that it may affect the occurrence of ischemic heart disease and hypertension. Almost one in four respondents had blood pressure values of > 139/89 mmHg. Almost one in ten respondents was receiving treatment for hypertension. A small number of respondents reported abnormal total cholesterol, HDL cholesterol and triglyceride levels. Conclusions. In the opinion of respondents, shift work can exacerbate hypertension and ischemic heart disease. Abnormal values of total cholesterol and its LDL and HDL fractions increased with age and length of work, while abnormal triglyceride values were reported most frequently by supervisors. It seems necessary to introduce training for shift workers, aimed at presenting them with the principles of prevention of cardiovascular diseases; for example, how to deal with stress, change eating habits, stop smoking and reduce coffee intake, and how to encourage physical activity and good sleep hygiene.
Decades of studies on alcohol dependence showed that it is a very complex and multifactorial disorder. Several receptor systems are involved in development and susceptibility to alcohol abuse; however, there are some which play a crucial role in its pathogenesis, e.g. dopaminergic or opioid system. In this paper, an effort is made to explain the role of endogenous opioid system activity in alcohol dependence. To achieve the goal, we use a unique model is used which shows mice lines that are divergently selected for high (HA) and low (LA) stress-induced analgesia. This process allowed for selecting individuals characterised by hyperactive (HA) or hypoactive (LA) opioid system. Basing on the performed experiments, we proved that delta opioid receptors play a critical role in the development of addiction. The most notable achievement is an unspecific reaction of mice with the hyperactive opioid system to naloxone – an unspecific opioid system antagonist, which is currently approved in the pharmacotherapy of dependent patients.

The system of human activity, which is established by genetics and regulated by outer and inner factors, is associated with many characteristics which maintain the body in the best condition and ensure appropriate life quality. Objective. To evaluate of life quality among male shift-workers. Methods: Research based on a self-devised questionnaire, conducted among 700 shift-workers, followed by statistical analysis of the results. Results. Nearly a half of respondents (43.00%) reported that shift-work influences the quality of their family life. Remarkably, such an opinion was often stated by people with children (46.01%) p<0.05, the divorced (58.22%), married people (44.74%) and bachelors (25.33%), respectively. Fathers usually indicated lack of contact with their family as well as irregular consumption of meals (66.91%). Almost every third respondent noted that their shift type of work negatively influence their sexual life (31.14%). Conclusions. It was shown that shift-work negatively influences the respondents’ life quality in the form of deterioration of the quality of family life; the respondents, regardless of marital status, age and having children, most often complained about the lack of contact with the family and irregular eating with them; negative influence on sexual life, which was the case in one-third of respondents. In order to encourage healthy behaviour and increase the quality of life of people performing shift-work, training and programmes should be introduced. These would help shift- workers to adjust their work time to their family and social life.
Introduction and objective. As landowners occupied with agricultural production comprise a sizeable part of the populations in mid- and western European countries, it seemed reasonable to assess the organization of health care systems concerning farmers and their families in Poland and Germany. Both countries have similar geographical conditions and rural environments. It so happens that in Poland the principles of the system of agricultural insurance (KRUS) is based on the experiences of Germany and France. State of knowledge. Basically, both in Poland and Germany, the agricultural health insurance companies provide the same insurance cover as other health insurance companies. In both countries, under certain conditions, in the case of illness, the insured farmers receive instead of sickness benefit operational assistance and home help. In spite of the similarities that characterize both administrations, many particular differences are to be noted, e.g. the farmers’ social insurance in Poland is subject to only one ministry, in contrast to Germany where two ministries are responsible for farmers’ social insurance. In Poland, KRUS is a monopolistic organization, whereas in Germany, nine similar independent structures fulfil the task of a health insurance company. Needless to say, many more funds are available for prevention, treatment and rehabilitation in Germany than in Poland, due to obvious differences in the overall national income.
Introduction: Acrylamide is used for wide range of industry purposes and it is produced in food during heating process. Foods with high acrylamide concentration include French fries, chips, bread crust, cereal, different baked goods. The electrophilic nature of acrylamide allows to interact with biological molecules. It is easily absorbed via the ingestion, inhalation or through the skin. Objective: Evaluation of dietary exposure to acrylamide in chosen population with respect to different age groups in South Poland and assessment of health risk. Material and Methods: Food consumption survey was conducted among 3 southern provinces in Poland. Studies involved 1470 participants. A semi-Quantitative Food Frequency Questionnaire was used. Consumption data of individuals were calculated into μg/kgbw/day. Statistics was calculated for both whole group and different age groups. MOE values were calculated. Results: Average acrylamide intake was 0.85 ± 0.82 μgacrylamide/kgbw per day and calculated 95th percentile was 1.70 μgacrylamide/kgbw/day. In general total dietary exposure decreased with age from 1.51 μgacrylamide/kgbw/day for the youngest group (6–12 years old) to 0.67 μgacrylamide/kgbw/day for the oldest one (42–60 years old). The main contributor of acrylamide in diet in all age groups are bakery products. The MOE values calculated for average acrylamide exposure in diet was 212 and 365 for BMDL10 0.18 and 0.31 mg/kgbw/day. Conclusions: Young population consume the highest amount of acrylamide thus any efforts should be done to rise their nutritional knowledge and to decrease intake of high acrylamide products (crisps and French fries). The need for promotion of knowledge how to decrease acrylamide level especially in home-made food regardless of age is necessary.
