  • The angle of trunk rotation and symmetry of a lower limb loading in musicians of a symphony orchestra in Poland: a pilot study concerning instrument-specific results
    The study aimed to evaluate the angle of trunk rotation (ATR) and symmetry of lower limb loading in professional musicians.
  • Effects of two recovery methods on the leg muscle fatigue of oceanauts in a manned submersible
    The cabin of the manned submersible is a narrow and sealed space. The long-time work of oceanauts is easy to cause muscle fatigue and stiffness, which reduces efficiency. This paper explored the relative more effective way to relieve leg muscle fatigue of the oceanauts in the manned submersible.
  • Healthcare workers highly affected during the COVID-19 epidemic wave in Poland prior to vaccination availability: seroprevalence study
    The aim of the study was to assess seroprevalence of anti-SARS-CoV-2 antibodies among healthcare workers (HCW) before introduction of vaccination, in selected areas in Poland as well as to identify potential risk factors and estimate the cumulative incidence of COVID-19 infections in this population.
  • The frequency of positive results of serological tests against SARS-CoV-2 in medical personnel of the Upper Silesian Agglomeration
    Silesia is one of the regions of Poland most affected by the COVID-19 epidemic. The high number of infections among residents increases the already high risk of SARS-CoV-2 infection among medical workers who, due to their work, are exposed to SARS-CoV-2 carriers more often than people from the general population. The aim of this study was to assess the prevalence of SARS-CoV-2 infection among health care workers from the Upper Silesian Agglomeration on the basis of the seroepidemiological study results.
  • Resorcinol - a method of determination in the air at workplaces
    Resorcinol (1,3-dihydroxybenzene) is a white solid used in the rubber, pharmaceutical, cosmetic, paint and varnish industries, etc. It is a harmful, irritating, methaemoglobin-forming and haemolytic substance. May cause kidney and liver damage. The aim of the study was to develop a method for determining resorcinol in air at workplaces, which would enable its concentration to be determined in the range of 0.1–2 maximum permissible concentration values.
  • Application of posturography for the assessment of the equilibrium system for the purposes of occupational medicine
    The examination of posturography enables the assessment of the functioning of the equilibrium system as a whole and the quantitative, apparatus-based verification of the clinical trial of Romberg. Therefore, the aim of the study was to assess the usefulness of posturography as the main test for the assessment of imbalances for the needs of occupational medicine.
  • Androgen receptor modulation and bladder cancer prevention – a short review
    The prevalence of bladder cancer (BCa) is 4 times higher in men as compared to women, and gender differences have been the focus of attention for few years. Androgen receptor (AR) may be a putative explanation for gender differences. It may also be related to unfavourable BCa progression and development because of the increased androgen sensitivity of urothelium to carcinogens. Moreover, cigarette smoking and occupational exposure to carcinogens have been reported to play contributory roles with the highest attributable risk of BCa. In this review, the authors attempt to summarize the seminal research works that synthesized current understanding of the central role of AR in the negative regulation of carcinogen detoxification activity in BCa. In particular, the authors discuss the regulatory effects of 3,3’-diindolylmethane on AR gene transcription through microRNA as its suggested effect on the prevention of BCa. Moreover, to show the still existing problem of occupational exposure and BCa incidence, the authors review recent studies in this area. Based on the rapidly accumulating scientific evidence, it seems pragmatic that androgen/AR-mediated interference in the detoxification mechanism may be inhibited by phytochemicals. Therefore, collectively, nutrition has a key role as gene–nutrient interactions are important contributors to BCa prevention, also through epigenetic modifications. Here, the authors have derived suggestions for future research.
  • Minority stress and selected mental disorders in people with gender dysphoria and gender incompatibility - a narrative review
    According to the International Classification of Diseases and Health Problems (ICD-11), compiled by the World Health Organization in 2019, gender incompatibility is a feeling of inconsistency between experienced and assigned sex, which does not have to be associated with discomfort or suffering. The aspect of suffering is emphasized in the understanding of the diagnostic unit which, according to the Diagnostic Criteria of Mental Disorders (DSM-5), is gender dysphoria. People with gender incompatibility are exposed to misunderstanding, persecution and stigmatization, which is often related to the experienced minority stress. The aim of the review was to analyze the available literature in terms of the relationship between gender dysphoria and some mental disorders and minority stress, and to draw attention to the suffering of sexually incompatible people in the context of social confrontation with the phenomenon of gender transposition. The unfavorable image of a sexually incompatible person created by some media, persecution and the prohibition of gender reassignment in some countries mean that a steady increase in the incidence of mental disorders in these patients can be expected. The main psychological problems in people with gender dysphoria with minority stress accompanying most of their life are related to the coexistence of depressive and anxiety disorders, self-destructive behaviors and a tendency to addiction. An important aspect of the functioning of people with gender dysphoria are also difficulties in taking up and maintaining employment and the fear of losing income due to trying to live in line with the perceived gender. The authors of the presented review want to emphasize the importance of minority stress in the lives of these people and the need for social education and a change in the approach to the concept of "employee". Excluding the record gender from the concept of "employee" could help people with gender incompatibility in their working life, reducing minority stress.
