The research is designed as a cross-sectional study. A questionnaire created using the Google Docs platform was used as an instrument. The sample consisted of 89 respondents of both sexes, aged 18 to 23 years. The analysis shows that there is a difference in maintaining hygienic habits before and after the introduction of the state of emergency. In 20.22% of cases, hygienic habits were better during the state of emergency, and after the mitigation of measures, compared to the period before the introduction of the state of emergency, and in 5.62% of respondents hygienic habits were worse, while in 74.16% of respondents there were no change in hygienic habits. The analysis of the use of disinfectants and masks shows that 60.68% of respondents used disinfectants and masks more often after mitigation of emergency measures compared to the period before the introduction of the state of emergency, 5.62% of respondents used less, while in 33.70 % of respondents there were no changes in the use of disinfectants and masks.</p> <p>The results of this study show a positive relationship between hygiene habits before and during the Covid 19 pandemic, and after mitigation, as well as between the use of disinfectants and masks before and during the Covid 19 pandemic, and after mitigation, which justifies further research in this area.</p> </abstract>ARTICLE2022-09-25T00:00:00.000+00:00External Validation of the 4C Mortality Score and PRIEST COVID-19 Clinical Severity Score in patients hospitalized with COVID-19 pneumonia in Greecehttps://sciendo.com/article/10.2478/rjim-2022-0015<abstract> <title style='display:none'>Abstract</title> <p><italic>Background:</italic> Prognostic scores can be used to facilitate better management of patients suffering from life-threatening diseases, provided that they have been tested in the population of interest.</p> <p><italic>Aim:</italic> To perform external validation of the 4C Mortality Score and PRIEST COVID-19 Clinical Severity Score.</p> <p><italic>Study Design:</italic> Prospective Observational Study.</p> <p><italic>Methods</italic>: Patients hospitalized with COVID-19 pneumonia in a tertiary hospital in Greece were enrolled in the study.

These skills support patient-centered care and improve the quality of care, and for nurses, they are a protective factor against burnout syndrome, also they improve team work. Therefore, it is so important to search for their determinants. The objective of the article was to evaluate the relation between empathy and type D personality with the level of social competences of primary healthcare nurses.</p> <p><bold>Material and methods.</bold> The research was conducted among primary healthcare nurses from the Lubelskie Voivodeship, using the following tools: The Social Competences Profile (PROKOS); Type D Personality Scale (DS-14), Empathic Understanding of Other People Questionnaire (KRE) and the sociodemographic data questionnaire.</p> <p><bold>Results.</bold> We analyzed the responses of 446 nurses. In the study group 65% of the nurses had an average level of social competences. The research also evaluated the level of empathy demonstrated by primary healthcare nurses. The mean score for the level of empathy was M=64.63 points (SD=10.16). When it comes to 39% of the researched group of nurses (n=172), they demonstrated type D personality. The correlation analysis proved that the level of empathy among primary healthcare nurses significantly (p&lt;0.001) supported their social competences. Furthermore the negative aff ectivity and social inhibition correlated significantly negatively (p&lt;0.001) with social skills of nurses.</p> <p><bold>Conclusions.</bold> Our research enabled us to discover the relations between empathy and type D personality with the level of social competences of primary healthcare nurses. Research further indicated insufficient level of social skills of nurses and the need to investigate factors, which could support their shaping. Further, in-depth research is required in this field, including quantitative analysis.</p> </abstract>ARTICLE2022-09-25T00:00:00.000+00:00Health problems of the patient after oncological treatment osteosarcoma with persistent thymushttps://sciendo.com/article/10.2478/pielxxiw-2022-0026<abstract> <title style='display:none'>Abstract</title> <p><bold>Introduction.</bold> Bone sarcomas, as rare tumour types, constitute only about 1% of malignant tumours. The treatment process is an additional burden on the human body, especially at a young age. The surgery has a long-term eff ect on the patient’s mobility and requires great eff ort and motivation to regain physical fitness. The discomfort resulting from having a persistent thymus gland makes it significantly more difficult for patients to return to their precancerous state.</p> <p><bold>Aim.</bold> The aim of this study is to diagnose the patient’s health problems resulting from the presence of persistent thymus gland and a history of oncological treatment for osteosarcoma, together with the presentation of measures to improve functioning in daily life.</p> <p><bold>Material and methods.</bold> The research method of the individual case study and the research techniques used were: interview, observation, measurement and analysis of medical records.

Professional help to people addicted and under the influence of drugs or other psychoactive substances should be provided primarily by health care institutions. An important and interesting issue seems to be the assessment of how people who have the most frequent contact with addicts are prepared to provide help, what is their knowledge and attitude to the phenomenon of drug addiction and to people addicted to psychoactive substances. The material for the research was a questionnaire for people who have contact and / or work professionally with people addicted to psychoactive substances. A total number of 253 people who had professional contact with people addicted to psychoactive substances were examined, including 102 men and 151 women. The respondents most often acquired knowledge in the field of drug addiction through the mass media. The exception is the professional group of doctors, which was the only one to refer to professional literature. Contact with drug addicts was not worried by 68.6% of doctors, 68.4% of policemen, 45.9% of nurses and only 39.0% of teachers. Fear may be caused mainly by possible aggressive behavior, which is feared by 49.8% of the respondents, including 58.3% of women and 37.2% of men. When it comes to 90.1% of respondents, they believe that the cause of aggression is the lack of control over their emotions. The results of the work can be helpful in creating new, satisfying solutions to difficult situations and developing cooperation characterized by empathy and acceptance.</p> </abstract>ARTICLE2022-09-25T00:00:00.000+00:00The development of the Metabolic-associated Fatty Liver Disease during pharmacotherapy of mental disorders - a reviewhttps://sciendo.com/article/10.2478/cpp-2022-0013<abstract> <title style='display:none'>Abstract</title> <p><bold>Introduction:</bold> Metabolic-associated Fatty Liver Disease (MAFLD) is a term for Non-alcoholic Fatty Liver Disease (NAFLD) that highlights its association with components of the Metabolic Syndrome (MetS). MAFLD is becoming a clinically significant problem due to its increasing role in the pathogenesis of cryptogenic cirrhosis of the liver.</p> <p><bold>Material and methods:</bold> The resulting work is a review of the most important information on the risk of MAFLD development in the context of the use of particular groups of psychotropic drugs. The study presents the epidemiology, with particular emphasis on the population of psychiatric patients, pathophysiology and scientific reports analyzing the effect of the psychotropic medications on MAFLD development.</p> <p><bold>Results:</bold> The drugs that can have the greatest impact on the development of MAFLD are atypical antipsychotics, especially olanzapine, and mood stabilizers (MS) - valproic acid (VPA). Their effect is indirect, mainly through dysregulation of organism’s carbohydrate and lipid metabolism.</p> <p><bold>Conclusions:</bold> The population of psychiatric patients is particularly vulnerable to the development of MAFLD. At the root of this disorder lies the specificity of mental disorders, improper dietary habits, low level of physical activity and tendency to addictions. Also, the negative impact of the psychotropic drugs on the systemic metabolism indirectly contributes to the development of MAFLD. In order to prevent fatty liver disease, it is necessary to monitor metabolic and liver parameters regularly, and patients should be screened by ultrasound examination of the liver. There are also important preventive actions from the medical professionals, including education of patients and sensitizing to healthy lifestyle.</p> </abstract>ARTICLE2022-09-25T00:00:00.000+00:00Epidural Analgesia for Labour: Comparing the Effects of Continuous Epidural Infusion (CEI) and Programmed Intermittent Epidural Bolus (PIEB) on Obstetric Outcomeshttps://sciendo.com/article/10.2478/rjaic-2021-0005<abstract> <title style='display:none'>Abstract</title> <sec><title style='display:none'>Objective</title> <p>In the last few years there is a trend of transiting from the continuous epidural infusion (CEI) method for epidural analgesia to a new method – programmed intermittent epidural analgesia (PIEB).

In order to apply SRW in woodworking and to fill the scientific base with indicators of the macro- and microstructures of the stump-root systems of individual species, studies were carried out on the main characteristics that are decisive for using composite materials in the industrial production. Based on the study results, it was found that there are differences in the internal structure between SRW and stemwood (SW). It was found that in all species, the width of annual rings in the SRW was greater than that in the SW, in particular, in pine (<italic>Pinus sylvestris</italic> L.) – by 84.62%; in spruce (<italic>Picea abies</italic> Karst.) – by 73.68%; in fir (<italic>Abies alba</italic>) – by 93.75%; in aspen (<italic>Populus tremula</italic> L.) – by 35.71% and in birch (<italic>Betula pendula</italic> Roth.) – by 105.00%. It has been found that the content of late wood in the SRW of coniferous tree species is less than that in the SW, on average by 20–25%, and the number of annual rings per 1 cm in the SRW is 40–52% less than in the SW. Differences in the microscopic structure between SRW and SW are revealed, which consist in the difference in the size of tracheids in softwoods and of vessels and fibres of libriform in hardwoods. It was found that the transverse dimensions of early tracheids in the SRW were larger than in the SW, in particular, in the radial direction by 19–33% and in the tangential direction by no more than 15%, and the interval of dimensions in the radial direction was 1.5–2.5. It was found that the early tracheids of root wood had thinner walls (by 19–28%) and a larger internal cavity (by 15–25%) compared to similar elements of SW. It was revealed that the diameters of vessels and fibres of libriform in SRW are greater than in SW, in particular, in aspen (<italic>Populus tremula</italic> L.) – by 20.41% for vessels and by 12.95% for libriform fibres and in birch (<italic>Betula pendula</italic> Roth.) – by 20.69% for vessels and by 18.41% for libriform fibres. The practical significance of the studies lies in the fact that the obtained characteristics of the structural components of the SRW can be used to predict the strength indicators of composite materials.</p> </abstract>ARTICLE2022-09-22T00:00:00.000+00:00Understanding forest land conversion for agriculture in a developing country context: An application of the theory of planned behaviour among a cohort of Nigerian farmershttps://sciendo.com/article/10.2478/ffp-2022-0012<abstract> <title style='display:none'>Abstract</title> <p>Natural and forest-rich ecosystems are determinants of environmental sustainability, which are threatened by forest land conversion for agricultural purposes, especially in less-developed contexts. Moreover, human behaviour is central to achieving the much desired ecologically balanced environment. Hence, a partly novel model informed by the theory of planned behaviour was used in the examination of forest land conversion for agricultural purposes.</p> <p>The study design was a cross-sectional survey targeted at a group of farmers of southwestern Nigeria. Data were collected using a structured questionnaire among 320 randomly selected crop farmers. Independent samples <italic>t</italic> test and one-way analysis of variance (ANOVA) were used to test the significance of difference in respondents' forest conversion behaviour across subgroups of gender and age/education, respectively. Stepwise multiple linear regression was used to identify the determinants of forest conversion behaviour.</p> <p>Results showed that 87.8% of respondents had ever engaged in forest conversion. Gender and education had no significant effect on forest conversion behaviour (<italic>p</italic> &gt; 0.05), but age did (<italic>p</italic> &lt; 0.05). Attitude was the best determinant (β = 0.289, <italic>r</italic> = 0.510, <italic>R</italic><sup>2</sup> = 0.260, <italic>p</italic> &lt; 0.001), subjective norm was better (β = 0.257, <italic>r</italic> = 0.496, <italic>R</italic><sup>2</sup> = 0.055, <italic>p</italic> &lt; 0.001), while perceived behavioural control was good (β = 0.131, <italic>r</italic> = 0.398, <italic>p</italic> &lt; 0.001, <italic>R</italic><sup>2</sup> = 0.012, <italic>p</italic> &lt; 0.005). The three variables correlated with intention by a degree of 57.2% (multiple <italic>R</italic> = 0.572), while they explained 32.7% of the variance in intention (<italic>R</italic><sup>2</sup> =0.327). Intention was also found to be a significant determinant of behaviour (β = 0.222, <italic>r</italic> = 0.222, <italic>R</italic><sup>2</sup> = 0.049, <italic>p</italic> &lt; 0.001).</p> <p>Middle age predisposes to, whereas younger and older age protects against greater extent of forest conversion. The partly novel model derived from the theory of planned behaviour proves the likely viability of the pursuit of socio-psychologically predicated interventions to enthrone forest conservation.</p> </abstract>ARTICLE2022-09-22T00:00:00.000+00:00Coleopterous predators of pine bark beetles in the last years of the outbreak recorded in Ukrainehttps://sciendo.com/article/10.2478/ffp-2022-0016<abstract> <title style='display:none'>Abstract</title> <p>The purpose of this study was to identify the species composition of coleopterous predators and their occurrence in different parts of the stem depending on the health condition of Scots pine (<italic>Pinus sylvestris</italic> L.) in the collapsing foci of bark beetles (Coleoptera: Curculionidae: Scolytinae). The research was carried out in 2019–2021 at 38 sample plots located in five State Forestry Enterprises of Sumy region (Ukraine). All sample plots are located in pure Scots pine stands in relatively poor forest site conditions. The relative density of stocking is 0.6–0.7, and the age of stands is between 60 and 110 years. The health condition for each tree was evaluated on visual characteristics by the classes: first – healthy; second – weakened; third – severely weakened; fourth – drying up; fifth – recently died and sixth – died over a year ago. Bark beetles’ nuptial chambers and predators were counted on 25 × 25 cm pallets, which were located at the lower, middle and upper parts of the stem with thin, thick and transitional bark, respectively. The significance of differences in the performance of predator species depending on the tree part, health condition and year was analysed using the nonparametric Kruskal–Wallis (K–W) test. The species composition of predators in different years, stem parts and tree health condition was compared using the Sorensen–Chekanovsky index.</p> <p>In the collapsing foci of bark beetles, the health condition of Scots pine in 2019–2021 tended to worsen. The infestation density of <italic>Ips acuminatus</italic> (Gyllenhal, 1827) and <italic>Ips sexdentatus</italic> (Boerner, 1767) was 0.62 ± 0.032 and 0.64 ± 0.017 nuptial chambers per 1 dm<sup>2</sup>, respectively, and also decreased in 2019–2021. In the galleries of bark beetles, seven species of coleopterous predators were collected: <italic>Aulonium ruficorne</italic> (Olivier, 1790) (Zopheridae), <italic>Platysoma elongatum</italic> (Leach, 1817) (Histeridae), <italic>Rhizophagus depressus</italic> (Fabricius, 1792) (Monotomidae), <italic>Corticeus pini</italic> (Panzer, 1799) (Tenebrionidae), <italic>Thanasimus formicarius</italic> (Linnaeus, 1758), <italic>Thanasimus femoralis</italic> (Zetterstedt, 1828) (Cleridae) and <italic>Salpingus ruficollis</italic> (Linnaeus, 1761) (Salpingidae). Two more species – <italic>Glischrochilus quadripunctatus</italic> (Linnaeus, 1758) (Nitidulidae) and <italic>Pytho depressus</italic> (Linnaeus, 1767) (Pythidae) – were singly collected in the foci. <italic>T. formicarius</italic> and <italic>P. elongatum</italic> were the most abundant. The ratio of predator–prey significantly increased from the upper to the lower part of the stem with thick bark. It, however, decreased in this stem part from the fourth to the sixth class of the health condition of the host tree.</p> </abstract>ARTICLE2022-09-22T00:00:00.000+00:00 () as the causative agent of bacterial wetwood disease of common silver fir ( mill.)https://sciendo.com/article/10.2478/ffp-2022-0017<abstract> <title style='display:none'>Abstract</title> <p>In recent decades, in many regions of the planet, there has been a widespread deterioration in the health condition and dieback of dark coniferous forests, caused by the combined action of various stress factors of biotic and abiotic origin. Forests with the participation of species of the genus <italic>Abies</italic> Mill. are particularly prone to degradation and dieback. The aim of the research is to study the symptoms of bacterial wetwood disease of <italic>Abies alba</italic> in the Ivano-Frankivsk region (state enterprise ‘Kutske forestry’) and to determine the anatomical, morphological and cultural properties of the pathogen. Some of the common symptoms of the disease include cracks and ulcers on the trunks with exfoliated rhytidome and exudate secretion, massive development of epicormic shoots, saturated xylem and phloem, wet rot with a characteristic odour of fermentation and pathological nucleus.</p> <p>Based on the syntaxonomic analysis of fir forests, an attempt has been made to identify the objective causes that lead to excessive development of phytopathogens and dieback of <italic>Abies alba</italic>. Our research established that the primary cause of dieback of <italic>Abies alba</italic> Mill. forests is a systemic, vascular–parenchymal disease known as bacterial wetwood of fir, which affects all plant tissues at all stages of ontogenesis.

The study was carried out in oak forests in the forest-steppe zone at a permanent sample plot. The experiment included the conversion of a low-value 8-year-old stand to improve its species composition. The sample plots were laid out in a fertile hardwood forest site. The conversion was realised by felling corridors of various widths (6, 9 and 12 m) and directions and planting English oak trees (<italic>Quercus robur</italic> L.) within them in rows. For the planted oaks, tending felling was carried out three times: weeding (8 years), cleaning (13 years) and thinning (32 years). A comparative analysis of mensuration characteristics (average height, diameter, growing stock, radial increment, health condition, etc.) was carried out for 32-year-old oak trees grown in the corridors and a part of a low-value stand in the unfelled strips after the tending felling. It was found that the average height and diameter at breast height of oaks in the 6, 9 and 12 m wide corridors of different cardinal directions did not differ significantly. The difference in oak stocks within 6 and 9 m wide corridors of different cardinal directions was also insignificant. The stock differences were statistically significant for 6 and 12 m wide corridors as well as for 9 and 12 m wide ones. The article made recommendations on the width of felled corridors and unfelled strips to effectively convert low-value young stands by the corridor method.</p> </abstract>ARTICLE2022-09-22T00:00:00.000+00:00en-us-1
