In recent years there has been an increasing number of cases of sudden cardiac death during physical effort. At present, life expectancy in the most developed countries grows rapidly and the number of people >65 years dramatically increases...

Time-related ageing of the organism brings about the limitations to all human beings. The ageing process pertains to all organs and neither does it spare the brain, although, apart from neurodegenerative diseases, the changes in brain's functions seem to be less detectable. Many studies that were conducted for years in ageing adults provide evidence that lifestyle in which psychic and physical activity is maintained significantly and positively affects brain plasticity, i.e., normal ability to learn and develop, and therefore this lifestyle serves as a protective agent for cognitive functions even in the case of degenerative changes of brain tissue...

BACKGROUND: The COVID-19 disease has a negative impact on the psychophysiological health of populations worldwide, including a decrease in overall physical performance and an increase in fatigue. Fatigue was one of the main symptoms reported by patients and persisted for several weeks after infection with COVID-19. Although the phenomenon of fatigue is still poorly understood, physical activity can be a supportive factor in combating feelings of fatigue and lack of energy. The purpose of this research was to assess the physical activity (PA) and fatigue levels of teachers in Poland and the United Kingdom in the first year after the COVID-19 pandemic...

BACKGROUND: COVID-19 vaccines for public use were approved at the turn of 2020 and 2021. The level of vaccination coverage against COVID-19 in Poland is one of the lowest in Europe. Despite scientific studies there are people who are afraid of vaccinations and spread false information about them. Vaccinations against COVID-19 allowed us to learn about the attitudes of people who decided to be vaccinated, which can be used to improve the effectiveness of the infectious diseases prevention in the work and public environment...

BACKGROUND: Workers who do monotonous and repetitive work in a static position often complain about fatigue and decreased work efficiency. Some studies indicate that to improve muscle fatigue, resistance strength training can be used. MATERIAL AND METHODS: To investigate the effect of 4-week inertial training on shoulder muscles' strength and muscles' fatigue resistance 44 female workers with disabilities were examined. The participants were randomized into the training group (T) (N = 32) and the control group (C) (N = 12)...

This paper discusses the potential of additive printing, the risks it poses to users' health (including 3D printer operators) and the effects of chemical substances released during the printing based on the available in vitro and in vivo studies. It was shown that substances emitted during printing with the commonly used acrylonitrile butadiene styrene (ABS) filament in additive manufacturing might have carcinogenic, hepatotoxic and teratogenic effects, as well as toxic effect on the respiratory system. The latest research on the mechanism of formation of particles and volatile organic compounds (VOCs) during 3D printing, the parameters affecting their potential emission, and trends in reducing these hazards are indicated...

This article discusses the classification of micro- and nanoplastics (MNP), the routes of their exposure and the effects of MNP on the reproductive, respiratory, digestive and immune systems based on in vitro and in vivo studies, as well as available epidemiological data. The MNP can enter our body through inhalation, food or skin. The presence of microplastics (MP) in tap, bottled and deep sea water, as well as in sea salt, fruit and vegetables has been demonstrated. Due to their small size, MNP can be absorbed and easily distributed through the blood and lymphatic vessel system to tissues and organs...

Analyses of the economic activity of the Polish population indicate that in 2023, about 7% of all employees performed, usually or sometimes, their work in the form of remote work. The purpose of this publication is to analyze the impact of working with screen-monitor devices on computer vision syndromes, musculoskeletal disorders, circadian rhythm, and to identify recommendations for the proper organization of the home office. A narrative review of the existing literature on the impact of work with the use of devices equipped with screen monitors on the health of employees was performed, as well as recommendations in the above-mentioned area were presented...

Healthcare workers are representatives of occupations that are most exposed to high levels of stress in the work environment. These characteristics of work increase the probability of suffering from mental disorders. One aspect of mental disorder prevention in the workplace is the role of healthcare managers as those people who are responsible for minimizing the negative impact of work-related stress factors. Their role can be performed by creating effective initiatives supporting workers' mental health. The need to support the implementation of such initiatives has been highlighted by the COVID-19 pandemic...

BACKGROUND: There are several techniques to diagnose post-traumatic stress disorder (PTSD) symptoms that correspond to the Diagnostic and Statistical Manual of Mental Disorders (DSM) classification of mental disorders. This study aimed at testing the reliability and construct validity of the Polish version of the PTSD-8. The results obtained in four professional groups of healthcare workers (physicians, nurses, paramedics, other occupations) were compared. MATERIAL AND METHODS: The PTSD-8 questionnaire includes questions on stress reactions manifested by intrusion (4 items), avoidance (2 items), or hypervigilance (2 items)...
