Objectives: This study is aimed at evaluation of bacterial air contamination in intensive poultry breeding. The evaluation was based on the determined levels of bacterial concentrations and qualitative identification of isolated microorganisms. Materials and Methods: The study covered 5 poultry houses: two hatcheries and three hen houses with the litter bed system. The air was sampled in three measurement series in the central part of the investigated workplace at the height of about 1.5 m over the ground, using portable measuring sets consisting of a GilAir 5 (Sensidyne, USA) pump and a measuring head filled with a glass microfibre filter (Whatman, UK). For the quantitative and qualitative analysis of microorganisms were used appropriate microbiological media. Results: The total concentrations of airborne mesophilic bacteria inside the poultry breeding houses ranged from 4.74×10⁴ cfu/m³ to 1.89×10⁸ cfu/m³. For Gram-negative bacteria, the range comprised the values from 4.33×10² cfu/m³ to 4.29×10⁶ cfu/m³. The concentrations of the cocci of Enterococcus genus ranged from 1.53×10⁴ cfu/m³ to 1.09×10⁷ cfu/m³, whereas those of other Gram-positive bacteria from 3.78×10⁴ cfu/m³ to 6.65×10⁷ cfu/m³. The lowest concentrations of each group of the examined microorganisms were noted in the second measurement series when the air exchange in the breeding houses was over twice higher than in first and third measurement series because the mechanical ventilation was supported by natural ventilation (opened gates in the buildings). The lowest concentrations of total bacteria were obtained in those buildings where one-day old chickens were kept. Gram-positive bacteria of the genera: Staphylococcus, Enterococcus, Corynebacterium, Brevibacterium, Micrococcus, Cellulomonas, Bacillus, Aerococcus, and Gram-negative bacteria of the genera: Pseudomonas, Moraxella, Escherichia, Enterobacter, Klebsiella, Pasteurella, Pantoea were isolated. It was shown that for most of the investigated livestock premises the total bacteria concentrations exceeded the reference value of 1.0×10⁵ cfu/m³. Furthermore, pathogenic microorganisms which are a potential threat to human health (Escherichia coli, Enterobacter cloacae, Klebsiella pneumoniae ssp. ozaenae, Enterococcus faecalis, Enterococcus faecium) were found among the identified bacteria. Conclusions: The results indicate that the hygienic conditions of the working environment connected with litter bed system production of poultry are affected by changes of the efficiency of ventilation and create a direct health risk to employees. They should use personal protective measures to protect their respiratory tract, especially when the gates in the hen houses are closed.

The global spread of the SARS COV-2 virus and the related Coronavirus Disease-19 (Covid-19) has forced the entire planet to suddenly adopt important safety standards and reorganize social reality. The present research investigates the perception of psychological, relational, and pedagogical risks and needs in the developmental age (3-18 years) by the parents of different Italian regions during the quarantine period. Specifically, we examined the opinions of parents regarding the rules of social distancing and the continuous and massive use of new technologies for distance learning (DL). The results showed that Italian parents have two main concerns: on the one hand, the emergency in terms of health and health-related aspects; on the other, the teaching, training, and educational trajectories of children. They manifested mistrust and scepticism towards institutions and the school world, in terms of both management competence and structural and infrastructural capacity; aspects perceived as concerns also for Phase 2 and 3 of the epidemic curve.

Homelessness is an urgent problem for any civilised society. It becomes the subject of examination of several fields of science such as social work, medicine, nursing, public health, law, sociology, psychology, theology, ethics, economy, environment and so on. In the paper, the authors analyze individual types of homelessness and social and health forms of assistance. They pay attention to the causes of homelessness, they describe the Charter of Fundamental Rights and Freedoms and the related right to treatment, the right to social services. In the Czech Republic, they approximate the importance, objectives and tasks of the association of asylum houses and dormitories, similarly indicating the situation in the Slovak Republic. They pay particular attention to health risks in the homeless community (mental disorders, infectious diseases, viral hepatitis, HIV/AIDS) and access to healthcare for the homeless.

The aim of the study was to determine the relation between the severity of cognitive impairment and the risk of falling among the elderly.The risk of falling was analyzed in 20 subjects (mean age 79,6 ±9,5). The study included persons with the Mini-Mental State Examination (MMSE) score below 27 (average MMSE 17,7 ±6,0). To assess the risk of falling the Fallscreen in a shortened version was used (PPA). The correlation of MMSE results with PPA results was analyzed.The mean value of the fall risk indicator was 4,9 ±0,2. Analyzing the relation between separate PPA tests, there was a significant negative moderate correlation of MMSE scores with reaction time (−0,54) and a similar positive correlation with knee extension strength (0,61). A high correlation of MME results was recorded with the fall risk indicator (−0,71).The strong correlation of cognitive impairment with the physiological profile among elderly shows that the higher the cognitive deficit, the higher the likelihood of a fall inci-dent in this group. When creating fall prevention programs, it is worth paying attention to improv-ing the muscular strength of the lower limbs and general reaction time, because these two elements may particularly affect the increased fall risk of people with cognitive impairment.

Celem pracy było określenie związku pomiędzy nasileniem zaburzeń poznawczych a ryzykiem upadku wśród osób starszych.Badaniami objęto 20 osób (średnia wieku 79,6 ±9,5). Do badań włączono osoby z wynikiem skali Mini-Mental State Examination (MMSE) poniżej 27 (średni MMSE 17,7 ±6,0). Analizę ryzyka upadku przeprowadzono, oceniając profil fizjologiczny FallScreen (PPA). Dokonano analizy korelacji wyników MMSE z wynikami PPA.Średnia wartość wskaźnika ryzyka upadku wyniosła 4,9 ±0,2. Analizując związek poszczególnych testów PPA, wykazano istotną ujemną umiarkowaną korelację wyników MMSE z czasem reakcji (-0,54) oraz podobną, dodatnią korelację z siłą wyprostu stawu kolanowego (0,61). Z kolei wysoką korelację wyników MME zarejestrowano w przypadku wskaźnika ryzyka upadku (-0,71).Wysoka korelacja zaburzeń poznawczych z profilem fizjologicznym wśród osób starszych pokazuje, iż im deficyt kognitywny jest wyższy, tym większe jest prawdopodo-bieństwo wystąpienia upadku w tej grupie. Tworząc programy prewencji upadków osób star-szych, warto zwrócić uwagę na poprawę siły mięśniowej kończyn dolnych oraz czasu reakcji, gdyż te dwa elementy mogą szczególnie wpływać na zwiększone ryzyko upadku osób z zaburzeniami poznawczymi.
