Electromagnetic radiation (EMR) emitting from the natural environment, as well as from the use of industrial and everyday appliances, constantly influence the human body. The effect of this type of energy on living tissues may exert various effects on their functioning, although the mechanisms conditioning this phenomenon have not been fully explained. It may be expected that the interactions between electromagnetic radiation and the living organism would depend on the amount and parameters of the transmitted energy and type of tissue exposed. Electromagnetic waves exert an influence on human reproduction by affecting the male and female reproductive systems, the developing embryo, and subsequently, the foetus. Knowledge concerning this problem is still being expanded; however, all the conditionings of human reproduction still remain unknown. The study presents the current state of knowledge concerning the problem, based on the latest scientific reports.

Lyme borreliosis (Lyme disease) caused by the Borrelia burgdorferi sensu lato spirochete is the most common tick-borne infection manifested by a wide spectrum of clinical symptoms. In Poland, the preventive health care does not comprise individual farmers as it is practiced in foresters. The objective of this study was to evaluate the exposure of Polish farmers to infection with B. burgdorferi, based on serological screening test and epidemiological investigation. A total of 3,597 farmers were examined for the presence of B. burgdorferi antibodies, as well as interviewed regarding exposure to ticks and prophylaxis of tick-borne diseases. The prevalence varied between 18.2 and 50.7 % suggesting a focal occurrence of borreliosis. A significant increase in the frequency of positive reactions in the oldest age ranges was observed, equaling 30.9 % in the range of 60–69 years and 53.6 % in the range of 80–91 years. The prevalence of the anti-B. burgdorferi antibodies of IgG class (14.7 %) was similar to that of IgM class (16.0 %). Seroreactivity to B. burgdorferi antigen was significantly higher in the group of farmers exposed to repeated tick bites. Significant relationships were also found between some other risk factors and occurrence of seropositive reactions to B. burgdorferi. To the best of our knowledge, this is the first study concerning seroprevalence to B. burgdorferi carried out on such a large group of farmers. Results indicate a high risk of B. burgdorferi infection among Polish farmers and associations between some risk factors and the presence of seropositive reactions.

IntroductionThe COVID-19 pandemic has significant socio-economic implications for numerous industries, including healthcare. Disruptions of essential health services were reported by nearly all countries around the world. A detailed assessment of the healthcare uptake is necessary to estimate the potential health effects of the COVID-19 pandemic on the population. This study aimed to assess the prevalence of barriers to accessing health services during the COVID-19 pandemic in Poland as well as to identify factors associated with the disturbed access to healthcare during the pandemic.MethodsThis cross-sectional survey was carried out among Internet users in Poland using the computer-assisted web interview technique. Data were collected between October and December 2021. The questionnaire included 32 questions on sociodemographic characteristics, the COVID-19 pandemic, health status, daily habits as well as the use of healthcare during the COVID-19 pandemic.ResultsData were obtained from 102928 adults, the mean age was 48.0 ± 14.2 years, and 57.2% were females. Most of the respondents had visited a doctor during the past 12 months (70.4%). Almost half of adults in Poland (49.7%) reported barriers to access health services in the past 12 months. Out of 51,105 respondents who had experienced barriers to accessing health services during the COVID-19 pandemic, only 54.3% had visited a doctor in the past 12 months. Long waiting time (39.5%) and temporary closure of healthcare facilities/transformation into a COVID-19 dedicated center (28.8%) were the most common barriers indicated by the respondents. In multivariable logistic regression, female gender, age 18–49 years, lack of higher education, living in cities between 51,000 and 200,000 residents or above 500,000 residents, and having at least one chronic disease were significantly (p < 0.05) associated with higher odds of experiencing barriers to accessing health services during the COVID-19 pandemic.ConclusionsThis study confirmed that the COVID-19 pandemic has worsened access to health services in Poland. During the pandemic, new barriers to accessing health services, such as the temporary closure of healthcare facilities for non-COVID patients were revealed. Findings from this study provided patients' perspectives on barriers to accessing health services in Poland that may be used by policymakers to reduce health inequalities.
