Bacterial complications in patients with coronavirus infection, new diagnostic and therapeutic possibilities.

We present the case of a young patient who developed pneumonia during the COVID-19 outbreak. The course of the disease with involvement of interstitial lung tissue atypical for bacterial infections, the picture of infection markers could indicate SARS-CoV-2. The patient was tested by PCR method on admission with negative results. Due to the atypical follow-up of the disease, suggesting a severe course of SARS, PCR testing of the material collected by BAL was performed BIOFIRE® FILMARRAY® Pneumonia plus Panel (bioMérieux). Legionella pneumophilla and coronavirus genetic materials were found. We conclude that in the described case there was a bacterial co-infection, paved by virus infection. The similar radiological picture of the two cases of pneumonia, as well as the similar infectious response in the blood, specific for atypical infections, may pose a problem in the differential diagnosis. The study was able to confirm the bacterial etiology of pneumonia and introduce targeted treatment. The patient was discharged from the hospital. We believe that in any case of pneumonia of non-bacterial etiology, extending the diagnosis with a PCR pulmonary panel allows early and effective treatment of patients. In the treatment of patients with pulmonary interstitial lesions in the course of virus infections, one should always keep in mind the possibility of atypical co-infections.

Tuberculosis in Poland in 2020.

AIM OF THE STUDY: To evaluate the main features of epidemiology of tuberculosis (TB) in 2020 in Poland and to compare with the situation in the European Union and European Economic Area (EU/EEA) countries. MATERIAL AND METHODS: Analysis of case-based data on TB patients from National TB Register, data on anti-TB drug susceptibility in cases notified in 2020, data from Statistics Poland on deaths from tuberculosis in 2019, data from National Institute of Public Health NIH - National Research Institute (NIPH NIH - NRI) on HIV-positive subjects for whom TB was an AIDS-defining disease, data from the report "European Centre for Disease Prevention and Control, WHO Regional Office for Europe. Tuberculosis surveillance and monitoring in Europe 2022 - 2020 data. Copenhagen: WHO Regional Office for Europe and Stockholm: European Centre for Disease Prevention and Control; 2022." RESULTS: In 2020, 3,388 TB cases were reported in Poland. The incidence rate was 8.8 cases per 100,000 with large variability between voivodeships from 5.5 to 13.3 per 100,000. A decrease in the incidence was found in 15 voivodeships, the most significant in Slaskie voivodship (63.9%). The number of all pulmonary tuberculosis cases was 3,237 i.e. 8.4 per 100,000. Pulmonary cases represented 95.5% of all TB cases. In 2020, 151 extrapulmonary TB cases were notified (4.5% of all TB cases). Pulmonary tuberculosis was bacteriologically confirmed in 2,573 cases (79.5% of all pulmonary TB cases, the incidence rate 6.7 per 100,000). The number of smear-positive pulmonary TB cases was 1,771 i.e. 4.6 per 100,000 (54.7% of all pulmonary TB cases). In 2020, there were 38 cases (15 of foreign origin) with multidrug resistant TB (MDR-TB) representing 1.6% of cases with known drug sensitivity. The incidence rates of tuberculosis were growing along with increasing age from 0.7 per 100,000 among children (0-14 years) to 15.0 per 100,000 among subjects in the age group 45-64 years, the incidence rate in the age group ≥65 years was 12.1 per 100,000. There were 39 cases in children up to 14 years of age (1.2% of the total) and 49 cases in adolescents between 15 and 19 years of age - rates 0.7 and 2.7 per 100,000 respectively. In 2020, there were 2,506 cases of tuberculosis in men and 882 in women. The TB incidence in men - 13.5 per 100,000 was 3.0 times higher than among women - 4.5. The biggest difference in the TB incidence between the two sex groups occurred in persons aged 50-54 years - 26.8 vs. 4.1 and in age group 55 to 59 years - 28.7 vs. 4.8. In 2020, there were 116 patients of foreign origin among all cases of tuberculosis in Poland (3.4%). In 2019, TB was the cause of death for 456 people (mortality rate - 1.2 per 100,000). CONCLUSIONS: TB incidence in Poland in 2020 was 36.7% lower than in 2019. Such significant declines in the incidence have not been observed in the last two decades. As in previous years, there were differences in incidence rates between voivodeships with an unexpectedly sharp decrease in incidence in Silesia (Slaskie voivodeship). The percentage of tuberculosis cases with bacteriological confirmation exceeded 78%, more than in EU/EEA countries (67.3%). The percentage of MDR-TB cases was still lower than the average in EU/EEA countries (1.6% vs. 3.8%). The highest incidence rates were found in Poland in the older age groups (EU/EEAaged 25 to 44). The percentage of children up to 14 years of age among the total number of TB patients was 1.2%, less than the average in EU/EEA countries (3.8%). The incidence of tuberculosis in men was three times higher than in women in Poland, and six times higher in patients aged 50 to 59. The impact of migration on the TB pattern in Poland has not yet become significant in 2020. The percentage of foreigners among TB patients was 3.4% (33% in EU/EEA countries).

Analysis of Determinants of Food Preferences in a Polish Population-Based Sample of Primary School Adolescents: Diet and Activity of Youth during COVID-19 (DAY-19) Study.

For the choices of food products, food preferences are crucial, as they influence the intake of nutrients and the resultant quality of diet, but in Poland, no studies of food preferences were conducted during the COVID-19 pandemic on a population of young adolescents. The aim of this study was to analyze the determinants of food preferences in a Polish population-based sample of primary school adolescents as part of the Diet and Activity of Youth during COVID-19 (DAY-19) Study. The DAY-19 Study focused on a national sample of a population of primary school adolescents who were recruited based on cluster sampling of participants from counties and schools, yielding a sample of 5039 individuals. Their food preferences were assessed using the Food Preference Questionnaire (FPQ), and they were compared in subgroups stratified by (1) gender: male and female; (2) age: younger (10-13 years) and older (14-16 years); (3) place of residence: urban and rural; (4) Body Mass Index (BMI): underweight, normal body weight, and overweight/obese (assessed based on Polish growth reference values); and (5) physical activity level: low and moderate (assessed using the International Physical Activity Questionnaire for children aged 10-13 (IPAQ-C) and adolescents aged 14-16 (IPAQ-A)). In the population of adolescents, no statistically significant differences in food preferences between subgroups stratified by gender were observed (p > 0.05). For boys, none of the studied factors (age, place of residence, BMI, physical activity level) was statistically significant determinant of food preferences (p < 0.05), while for girls, all of them were statistically significant determinants (p > 0.05). All the assessed factors (age, place of residence, BMI, physical activity level) in girls were associated with preferences for snacks, and older girls, those from a rural environment, those who were underweight and overweight/obese, as well as those having a low physical activity level declared a higher preference for snacks than younger ones (p = 0.0429), those from an urban environment (p = 0.0484), those of a normal body weight (p = 0.0091), and those having a moderate physical activity level (p = 0.0083). Similarly, girls from rural environments declared a higher preference for starches than those from urban environments (p = 0.0103), and girls having a low physical activity level declared a higher preference for fruit than those having a moderate physical activity level (p = 0.0376). Taking this into account, the population of girls, in particular, needs dedicated educational actions to support proper nutritional habits. Additionally, older age, living in a rural environment, being underweight and overweight/obese, and having a low physical activity level may be indicated as factors predisposing one to food preferences potentially promoting unhealthy dietary habits.

A serological survey of pathogens associated with the respiratory and digestive system in the Polish European bison (Bison bonasus) population in 2017-2022.

BACKGROUND: The European bison (Bison bonasus) is a near threatened species and requires health monitoring. The aim of the present study was to determine the prevalence of antibodies to pathogens known to cause respiratory and digestive illness in ruminants. RESULTS: In the studied 328 European bison, the highest seroprevalence was observed for Bovine herpesvirus-1 (BoHV-1) (50.27%), Bovine Coronavirus (BCoV) (26.36%), and Bluetongue Virus (BTV) (12.83%). For Mycoplasma bovis strains and Bovine Viral Diarrhea Virus (BVDV), positive results were rare. Interestingly, a higher prevalence of BTV antibodies was noted in the northeastern populations and older animals. CONCLUSIONS: Our findings indicate that the Polish European bison population appears to have considerable contact with BoHV-1; however, this does not appear to be of great significance, as clinical symptoms and post-mortem lesions are rarely noted in Polish European bison population. The high seroprevalence of BTV in the north-east of Poland is an ongoing trend, also noted in previous studies. It is possible that European bison may perpetuate the virus in this region. This is the first report of antibodies for BCoV in European bison.

Multiscale Geographically Weighted Regression in the Investigation of Local COVID-19 Anomalies Based on Population Age Structure in Poland.

A growing number of various studies focusing on different aspects of the COVID-19 pandemic are emerging as the pandemic continues. Three variables that are most commonly used to describe the course of the COVID-19 pandemic worldwide are the number of confirmed SARS-CoV-2 cases, the number of confirmed COVID-19 deaths, and the number of COVID-19 vaccine doses administered. In this paper, using the multiscale geographically weighted regression, an analysis of the interrelationships between the number of confirmed SARS-CoV-2 cases, the number of confirmed COVID-19 deaths, and the number of COVID-19 vaccine doses administered were conducted. Furthermore, using maps of the local R2 estimates, it was possible to visualize how the relations between the explanatory variables and the dependent variables vary across the study area. Thus, analysis of the influence of demographic factors described by the age structure and gender breakdown of the population over the course of the COVID-19 pandemic was performed. This allowed the identification of local anomalies in the course of the COVID-19 pandemic. Analyses were carried out for the area of Poland. The results obtained may be useful for local authorities in developing strategies to further counter the pandemic.

Implementation of the preventive vaccination program in the time of the COVID-19 pandemic - single center study.

INTRODUCTION: In addition to many diagnostic and therapeutic procedures, the COVID-19 pandemic also limited prophylaxis, including the implementation of the vaccination program among children. OBJECTIVE: The aim of the study was to assess the implementation of the vaccination program in the area covered by the care of patients of a selected Primary Health Care clinic in the city of Krakow in the field of selected vaccinations during the COVID-19 pandemic. MATERIAL AND METHODS: A retrospective study based on secondary data was conducted in a selected clinic (Kraków, Poland) that cares for 1,982 children aged 0-19 years. An analysis of the vaccination coverage in selected groups of children in 2019, 2020 and 2021 was carried out based on annual reports (MZ-54). Vaccination coverage against: diphtheria, tetanus, whooping cough, measles, mumps, rubella, influenza and pneumococcal infection was analyzed. The collected data were analyzed using descriptive statistics, Chi2 test and Fisher's exact test. RESULTS: In the general vaccination status of two-year-olds, no significant differences were observed in the period 2019-2021 (p=0.156). The percentage of fully vaccinated increased from 77.6% in 2019, to 81.5% in 2020 and to 85.2% in 2021. However, a high rate of vaccination refusals was observed in 2021 (4.1%) in this group. The percentage of 2-year-olds vaccinated against pneumococci (PCV) and 3-year-olds against diphtheria, tetanus, pertussis (DTP), and measles, mumps, rubella (MMR) in the years 2019-2021 was increasing. For DTP and MMR, this increase was significant (p<0.05). In the group of older children, in 2020 the percentage of 7- and 15-year-olds vaccinated decreased compared to 2019 and 2021, but the difference was insignificant (p>0.05). A significant difference in vaccination coverage was observed in the group of 19-year-olds, in which in 2020 the percentage of vaccinated was 58% (in 2019 - 74.6%, in 2021 - 81%). The largest number of children under the age of 5 were vaccinated against influenza in 2021, but it was only less than 2% of this group. CONCLUSIONS: Sanitary restrictions introduced during the COVID-19 pandemic did not significantly affect the vaccination status of children in selected age groups against the analyzed vaccine-preventable diseases. The exception is the group of 19-year-olds, whose vaccination coverage in 2020 was much lower than in 2019 and 2021. In addition, an increase in refusals of vaccination was observed, reaching 4.1% in 2021 in the group of the youngest patients.

POLCOVID: a multicenter multiclass chest X-ray database (Poland, 2020-2021).

The outbreak of the SARS-CoV-2 pandemic has put healthcare systems worldwide to their limits, resulting in increased waiting time for diagnosis and required medical assistance. With chest radiographs (CXR) being one of the most common COVID-19 diagnosis methods, many artificial intelligence tools for image-based COVID-19 detection have been developed, often trained on a small number of images from COVID-19-positive patients. Thus, the need for high-quality and well-annotated CXR image databases increased. This paper introduces POLCOVID dataset, containing chest X-ray (CXR) images of patients with COVID-19 or other-type pneumonia, and healthy individuals gathered from 15 Polish hospitals. The original radiographs are accompanied by the preprocessed images limited to the lung area and the corresponding lung masks obtained with the segmentation model. Moreover, the manually created lung masks are provided for a part of POLCOVID dataset and the other four publicly available CXR image collections. POLCOVID dataset can help in pneumonia or COVID-19 diagnosis, while the set of matched images and lung masks may serve for the development of lung segmentation solutions.

COVID-19-associated acute pancreatitis: a systematic review of case reports.

INTRODUCTION: Coronavirus disease 2019 (COVID-19) mainly involves the respiratory system but can also affect the digestive system and cause several gastrointestinal manifestations. Acute pancreatitis has been reported as one of the rare presentations of COVID-19. This study aimed to systematically review case reports on COVID-19-associated acute pancreatitis. METHODS: Publications were retrieved through a comprehensive search in four databases on October 1, 2021. Eligible ones that demonstrated the potential association of acute pancreatitis and COVID-19 were included for data extraction. RESULTS: After screening 855 citations, 82 articles containing 95 cases were included, and their data were extracted. The most common presentation was abdominal pain (88/95, 92.6%), followed by nausea/vomiting (61/95, 64.2%). Mortality was reported in 10.5% of cases. The initial presentation was acute pancreatitis, COVID-19, and concomitant in 32.6% (31/95), 48.4% (46/95), and 18.9% (18/95) of cases, respectively. Among the included cases, acute pancreatitis severity was associated with ICU admission, COVID-19 severity, and the outcome. Also, the initial presentation was associated with COVID-19 severity (P values ˂0.05). CONCLUSIONS: Current evidence indicates that acute pancreatitis can present before, after, or concomitant with COVID-19. Appropriate investigations should be performed in cases with suspicious clinical presentations. Longitudinal studies should address whether or not, there is a causative relationship between COVID-19 and acute pancreatitis.

Analysing COVID-19 treatment outcomes in dedicated wards at a large university hospital in northern Poland: a result-based observational study.

OBJECTIVES: Presenting outcomes of patients hospitalised for COVID-19 should be put in context and comparison with other facilities. However, varied methodology applied in published studies can impede or even hinder a reliable comparison. The aim of this study is to share our experience in pandemic management and highlight previously under-reported factors affecting mortality. We present outcomes of COVID-19 treatment in our facility that will allow for an intercentre comparison. We use simple statistical parameters-case fatality ratio (CFR) and length of stay (LOS). SETTING: Large clinical hospital in northern Poland serving over 120 000 patients annually. PARTICIPANTS: Data were collected from patients hospitalised in COVID-19 general and intensive care unit (ICU) isolation wards from November 2020 to June 2021. The sample consisted of 640 patients-250 (39.1 %) were women and 390 (60.9 %) were men, with a median age of 69 (IQR 59-78) years. RESULTS: Values of LOS and CFR were calculated and analysed. Overall CFR for the analysed period was 24.8%, varying from 15.9 % during second quarter 2021 to 34.1% during fourth quarter 2020. The CFR was 23.2% in the general ward and 70.7% in the ICU. All ICU patients required intubation and mechanical ventilation, and 44 (75.9 %) of them developed acute respiratory distress syndrome. The average LOS was 12.6 (±7.5) days. CONCLUSIONS: We highlighted the importance of some of the under-reported factors affecting CFR, LOS and thus, mortality. For further multicentre analysis, we recommend broad analysis of factors affecting mortality in COVID-19 using simple and transparent statistical and clinical parameters.

Lifestyle Changes during the SARS-CoV-2 Pandemic as Predictors of BMI Changes among Men and Women in Poland.

BACKGROUND: Social isolation during the SARS-CoV-2 pandemic affected people's body weight, therefore, this study was designed to evaluate the association between lifestyle elements and the change in BMI during lockdown. METHODS: This retrospective observational study involved 290 questionnaires completed by adult participants divided into three groups according to BMI change during isolation. The structured questionnaire included a general description of the study objective and collected data regarding sociodemographics, anthropometrics, physical activity, sedentary behaviour, sleep duration, and food intake pre- and during COVID-19 lockdown. RESULTS: A decrease or increase in BMI was found in 23.6% and 47.8% of women and 18.5% and 42.6% of men, respectively. Among those who lost weight, 46.5% of women and 40% of men followed a diet of their own choice, 30.2% of women and 25% of men changed their product mix and reduced their intake, 40% of men stopped eating outside the home. An increase in BMI was associated with increased food intake (32.2% of women and 28.3% of men), increased sleep duration on weekdays (49.2% of women and 43.5% of men) and, in more than 50% of subjects, decreased physical activity. In women, increased BMI was associated with the highest frequency of snacking (p = 0.0003), the highest intake of sweets (p = 0.0021), and in men with the highest intake of alcohol (p = 0.0017). CONCLUSIONS: The observed changes in BMI during social isolation were the result of lifestyle modifications including dietary behaviour and differed by gender.

Risk factors for complicated course and recurrence of Clostridioides Difficile infections during COVID-19 pandemic.

INTRODUCTION: The primary symptom of Clostridioides difficile infection (CDI) is diarrhea of varying severity. Both malnutrition and clinical nutrition increase the risk for contracting Clostridioides difficile (C. difficile) infection and the likelihood of relapses. Moreover, the risk for recurrence is higher if there is infection with a hypervirulent strain (NAP1/BI/027). Hypoalbuminemia predisposes to a severe course of the disease and morbidity. MATERIAL AND METHODS: Analysis was carried out of the data regarding patients hospitalized at the Regional Hospital for Infectious Diseases in Warsaw from 01 January 2020 to 31 December 2021 who were diagnosed with C. difficile infection. A severe course of infection was diagnosed when a blood test showed a leukocyte count greater than or equal to 15,000/µl and/or a creatinine concentration >1.5 mg/dl (>132.6 mmol/l). RESULTS: Clostridioides difficile infection was the reason for 185 hospitalizations (involving 108 women and 77 men), of 167 patients aged from 22 to 93 years old. There were 68 (37%) cases of recurrent infection. Seventy-five (41%) infections met the study's criteria for severe CDI, and 12 (7%) patients died. Out of the total number of hospitalizations, 41 (22%) were due SARS-CoV-2 co-infection. PCR tests detecting binary toxin revealed 34 (18%) positive results. Infection with a hypervirulent strain was an independent risk factor for the recurrence of diarrhea which had C. difficile etiology. Overall, during an episode of diarrhea, one antibacterial drug was used in 139 cases (75%), two in 27 (15%), three in 14 (8%) situations, and four - twice (1%). Among these, drugs not recommended for the treatment of CDI were used in 21 (11%) cases. The number of antibacterial drugs administered during an episode of diarrhea was an independent risk factor for the death of the infected person. Clinical nutrition was applied during 19 hospitalizations (10%), out of which 12 (63%) cases showed a severe course of C. difficile infection, while four patients (21%) died. Using clinical nutrition methods was an independent risk factor for a severe course of the disease and patient death. CONCLUSIONS: Clinical nutrition and the number of antibiotics used during an episode of diarrhea are independent risk factors for the death of a patient with CDI. Infection with a hypervirulent strain increases the risk for relapse.

A critical assessment of a protected area conflict analysis based on secondary data in the age of datafication.

Recently, a global trend towards a broader use of secondary data in social sciences has been reinforced by the COVID-19 pandemic. This evoked doubts about the validity of the results unless restrictive assessment procedures are implemented. To address this need in the field of protected area (PA) conflict analysis, we propose a three-fold approach (theory-, method-, and cross-scale simulation-driven) to assess the usefulness of the utilized state register dataset and the indicator analysis methodology for the multi-level recognition of PA conflict determinants. With the ultimate aim to inform case study selection, we processed 187 relevant indicators from the official Statistics Poland register for a Lesser Poland region. We distinguished five types of PA conflict determinants in Lesser Poland ('urbanity', 'agriculture', 'tourism', 'small-scale entrepreneurship', and 'sprawl') and respective groups of 15 clusters comprising local-level units. For one cluster, we juxtaposed the obtained results with secondary data from another source (Internet content) and for a specific PA (Tatra National Park). Although the reported conflict issues corresponded to the indicator-derived descriptors of the cluster, in the theory-driven phase of the assessment, the state register failed to address the key prerequisites of PA conflicts. We have demonstrated that, in crisis conditions such as COVID-19, the proposed method can serve as a proxy for a multi-level recognition of PA conflict potentials, provided that it synthesises the results of different methodological approaches, followed by in-person interviews in the selected case studies.

COVID-19-related social isolation and symptoms of depression and anxiety in young men in Poland: Does insomnia mediate the relationship?

The need for physical distancing due to COVID-19 mitigation efforts forced prolonged social isolation, which may affect sleep and lead to mental health problems. Previous research has shown that young adults are particularly vulnerable to psychological stress caused by social isolation, the negative psychological impact of the pandemic, and greater frequency and severity of sleep problems. Therefore, the main goal of the present study was to examine whether insomnia could constitute a mediation mechanism that explains the relationship between social isolation experienced during the COVID-19 pandemic and mental health outcomes (depression and anxiety) reported up to 1.5 years later. The study was conducted among young (M±SD; 24.08±3.75) men (N = 1025) in Poland. Data were collected by means of self-report questionnaires, including The Social Isolation Index, The Athens Insomnia Scale, The State-Trait Anxiety Inventory (STAI-S) and Beck's Depression Inventory (BDI-II). The results show that insomnia mediates the relationships between social isolation and both anxiety and depression. The current findings emphasize the role of insomnia in the relationships between social isolation experienced during COVID-19 and negative emotional states. From a clinical perspective, the results suggest that implementing therapeutic components that address social isolation in insomnia treatment programs may prevent the development of depression and anxiety symptoms among young men.

Diabetes as a risk factor of death in hospitalized COVID-19 patients - an analysis of a National Hospitalization Database from Poland, 2020.

Introduction: Diabetes is one of the comorbidities associated with poor prognosis in hospitalized COVID-19 patients. In this nationwide retrospective study, we evaluated the risk of in-hospital death attributed to diabetes. Methods: We analyzed data from discharge reports of patients hospitalized with COVID-19 in 2020 as submitted to the Polish National Health Fund. Several multivariate logistic regression models were used. In each model, in-hospital death was estimated with explanatory variables. Models were built either on the whole cohorts or cohorts matched with propensity score matching (PSM). The models examined either the main effects of diabetes itself or the interaction of diabetes with other variables. Results: We included 174,621 patients with COVID-19 who were hospitalized in the year 2020. Among them, there were 40,168 diabetic patients (DPs), and the proportion of DPs in this group was higher than in the general population (23.0% vs. 9.5%, p<0.001). In this group of COVID-19 hospitalizations, 17,438 in-hospital deaths were recorded, and the mortality was higher among DPs than non-diabetics (16.3% vs. 8.1%, p<0.001). Multivariate logistic regressions showed that diabetes was a risk factor of death, regardless of sex and age. In the main effect analysis, odds of in-hospital death were higher by 28.3% for DPs than for non-diabetic patients. Similarly, PSM analysis including 101,578 patients, of whom 19,050 had diabetes, showed that the risk of death was higher in DPs regardless of sex with odds higher by 34.9%. The impact of diabetes differed among age groups and was the highest for patients aged 60-69. Conclusions: This nationwide study confirmed that diabetes was an independent risk factor of in-hospital death in the course of COVID-19 infection. However, the relative risk differed across the age groups.

Contact between European bison and cattle from the cattle breeders' perspective, in the light of the risk of pathogen transmission.

Pathogens transmitted between wildlife and domestic animals can pose a threat to endangered species, undermine conservation efforts in wildlife, and affect productivity and parasite control in domestic animals. There are several examples of pathogen transmission between European bison and other animals. The present study surveyed breeders from the vicinity of four large wisent populations in eastern Poland about observed contacts between wisent and cattle. Such contacts were noted by 37% of breeders, indicating a significant risk of contact between European bison and cattle in the study areas, even in the areas where the European bison live mainly in a forest complex, i.e., in the Borecka Forest. A higher potential risk of contacts between European bison and cattle was noted in the Bialowieska Forest and the Bieszczady Mountains than in the Borecka and Knyszynska Forests. In the Bialowieska Forest, the risk of viral pathogen transmission resulting from contacts is higher (more direct contacts), and in the case of the Bieszczady Mountains, the probability of parasitic diseases is higher. The chance of contacts between European bison and cattle depended on the distance of cattle pastures from human settlements. Moreover, such contact was possible throughout the year, not only in spring and fall. It appears possible to minimize the risk of contacts between wisent and cattle by changing management practices for both species, such as keeping grazing areas as close as possible to settlements, and reducing the time cattle graze on pastures. However, the risk of contact is much greater if European bison populations are large and are dispersed beyond forest complexes.

Strategic and entrepreneurial abilities: Surviving the crisis across countries during the Covid-19 pandemic.

This paper seeks to identify organisational abilities that influence the company's survival during crises. To address this issue, first-through literature review-we identified five groups of crucial organisational abilities that companies pursue during the crisis, i.e., strategic, technological, collaboration, entrepreneurial and relational. We have also identified four objectives that relate to surviving the crisis. Next, we have scrutinised 226 companies from two sides of the world, Poland (Europe) and Morocco (Africa), during the Covid-19 crisis. Quantitative analysis using Structural Equations Modelling demonstrated that surviving during a crisis depends mostly on strategic and entrepreneurial abilities such as the ability to shift resources quickly, organise the work in the firm effectively and plan strategically, as well as diversify its products and services perceived as critical.

Mental condition and physical activity of individuals working during the COVID-19 pandemic in Poland.

OBJECTIVES: The study assessed quality of life and depression in working people during COVID-19 pandemic, relative to their physical activity. MATERIAL AND METHODS: The study involved 1194 people living in south-eastern Poland, and assessed life satisfaction (Life Satisfaction Questionnaire - 9 [LISAT-9]), quality of life (World Health Organization Quality of Life - BREF [WHOQoL-BREF]), depression (Beck Depression Inventory [BDI]) and physical activity. RESULTS: The respondents on average scored 4.32 in LISAT-9; respectively 66.2, 68.3, 69.6 and 63.5 in physical, psychological, social and environment domains of WHOQoL-BREF and 9.2 in BDI. Regularly performed physical activity positively affected the scores in all the psychometric tests in women with higher and secondary education and in men with vocational education. Women presented lower life satisfaction, poorer quality of life and higher level of depression than men. The psychometric scores were also differentiated by type of employment and job. Depression was identified in 44% of all the respondents. CONCLUSIONS: Individuals who are economically active during the pandemic report good quality of life and no or only mild signs of depression. Working people with higher education cope more effectively with adversities of the pandemic, compared to those with lower education. Int J Occup Med Environ Health. 2023;36(2):274-90.

Not so good hybrid work model? Resource losses and gains since the outbreak of the COVID-19 pandemic and job burnout among non-remote, hybrid, and remote employees.

OBJECTIVES: The COVID-19 pandemic contributing to the dissemination of alternative work models such as fully remote or hybrid work models. The present study focused on these 2 types of unplanned changes in the working environment. The conservation of resources theory, the first aim of this study was to examine the predictive role of resource losses and gains since the outbreak of the COVID-19 pandemic in job burnout. Moreover, the authors investigated how non-remote, remote, and hybrid employees differ in resource losses and gains and job burnout. MATERIAL AND METHODS: A cross-sectional online comparative study was conducted a year after the outbreak of the COVID-19 pandemic. The respondents provided sociodemographic data, reported their current work model, and completed validated measures of resource losses and gains and job burnout: the Conservation of Resources Evaluation and the Oldenburg Burnout Inventory. Based on the data collected from 1000 working adults from the Polish population, the authors tested the differences in losses and gains of different categories of resources and job burnout components between the 3 groups of employees representing distinct working models, i.e., non-remote, hybrid, and remote. RESULTS: In general, the associations of losses and gains with job burnout subscales have been confirmed, regardless of the level of analysis of losses and gains. The authors' findings indicated that hybrid workers experienced significantly higher resource losses and gains (both in general and in different domains) in comparison to non-remote and remote workers. In turn, non-remote employees scored significantly higher on disengagement, which is one of the job burnout components.

Prevalence of Physical Violence in the Medical-Forensic Approach in the Years 2015-2020 in City and Neighboring Municipalities: Perspectives from Poland-Poznan Study.

Forensic medical opinions serve the appropriate classification of a crime against health. Violence, a multifaceted phenomenon, requires forensic medical examination in the case of causing damage to health. Due to the effects caused by the perpetrator, the damage to health is divided into severe, medium, and light. This study analyzed 7689 incidents of violence from 2015-2020, taking place in the area subordinate to the Provincial Police Headquarters in Poznan, based on anonymized documentation of forensic medical examinations performed at the Department of Forensic Medicine in Poznan at the request of the Police and privately. The analysis took into account: units ordering the test, type of exposure, medical help, sex and age of the victim, places of the incident, classification and localization of injury, manner of impact, attitude of the perpetrator to the victim, profession of the victim, gender of the perpetrator, and remarks. In Poland, statistics on violence victims are underestimated, resulting from the low reporting of crimes committed to law enforcement authorities. There is a need for programs to educate the perpetrator of violence on methods of conflict resolution and programs to prevent violence, covering events taking place in public spaces.
