RESUMO
Background/Objectives: The COVID-19 pandemic was a time of limited direct contact with other people. The aim of this study was to determine the role of positive orientation and sociodemographic variables in the feelings of global, social and emotional loneliness and to seek predictors for loneliness among students during the COVID-19 pandemic. Methods: The study was conducted on a group of 798 students at the University of Warmia and Mazury in Olsztyn (Poland) between January and March 2022. The empirical data were gathered with the following research tools: the Positive Orientation Scale and the De Jong Gierveld Loneliness Scale-DJGLS. Results: The study found a correlation (r = -0.370; p < 0.001) between positive orientation and emotional loneliness. The level of loneliness was significantly higher in students who greatly reduced their social contact, compared to those who reduced them moderately (p < 0.001). The intensity of social loneliness among women was lower (p < 0.001) than among men. Those who lived with their families or with a close companion felt less intense emotional loneliness (p < 0.001) than those who lived alone. Conclusions: A positive orientation, which manifests itself in a favourable opinion about oneself and in attaching weight to positive aspects of life, was found to be the main determinant of the feelings of global and emotional loneliness. However, it did not prove to be a predictor of social loneliness in the group of students under study.
RESUMO
(1) Background: Social distancing and closing down public spaces associated with learning, leisure and physical activity limited the spread of COVID-19. These measures had an impact not only on the economy and education but also on health behaviours and the quality of life of individuals affected by the restrictions. The aim of this study was to identify the role of health behaviours in the perception of the quality of life of students during the COVID-19 pandemic. (2) Methods: This study was conducted among 796 students of the University of Warmia and Mazury in Olsztyn in the first quarter of 2022. Subgroup 1 consisted of students at the Public Health School (n = 428; 53.8%) and subgroup 2 consisted of students belonging to the Faculty of Veterinary Medicine (n = 368; 46.2%). The diagnostic survey method was applied, and an original survey questionnaire, the Health Behaviour Inventory and the Quality of Life Questionnaire (WHOQoL-Bref version) were used. (3) Results: The largest contribution to the prediction of quality of life of students in subgroup 1 was made by a positive mental attitude related to avoiding too strong emotions, which explained 19% of the result variability in the somatic domain (ßeta = 0.24; R2 = 0.21), 20% of the result variability in the psychological domain (ßeta = 0.36; R2 = 0.20), 16% of the result variability in the social domain (ßeta = 0.52; R2 = 0.17) and 17% of the result variability in the environmental domain (ßeta = 0.19; R2 = 0.19). Moreover, in subgroup 2, a predominantly positive mental attitude significantly predicted quality of life in the somatic domain, explaining 23% of the result variability (ßeta = 0.24; R2 = 0.26), while it explained 25% of the result variability in the psychological domain (ßeta = 0.47; R2 = 0.25), 16% of the result variability in the social domain (ßeta = 0.46; R2 = 0.17) and 21% of the result variability in the environmental domain (ßeta = 0.38; R2 = 0.23). (4) Conclusions: Positive correlations between health behaviours and the quality of life among the study participants were determined. Health-promoting behaviours had a beneficial impact on the respondents' quality of life during the COVID-19 pandemic. The category of health behaviours described as a positive mental attitude was an important predictor for the participants' quality of life.

Background: Percutaneous pericardiocentesis represents a salvage procedure in case of cardiac tamponade and diagnostic procedure in chronic pericardial effusion of unknown source. The study aimed to analyze the clinical characteristics of patients subject to pericardiocentesis and the predictors of in-hospital mortality. Methods: The study represents a registry that covered consecutive patients undergoing percutaneous pericardiocentesis from 2011 to 2022 in high-volume tertiary reference center. Electronic health records were queried to obtain demographic and clinical variables. The primary endpoint was in-hospital mortality, while secondary endpoint was the need for recurrent pericardiocentesis. Results: Out of 132 456 patients hospitalized in the prespecified period, 247 patients were subject to percutaneous pericardiocentesis (53.9% women; median age of 66 years) who underwent 273 procedures. In-hospital death was reported in 14 patients (5.67%), while recurrent pericardiocentesis in 24 patients (9.72%). Iatrogenic cause was the most common etiology (42.5%), followed by neoplastic disease (23.1%) and idiopathic effusion (14.57%). In logistic regression analysis in-hospital mortality was associated with myocardial infarction (MI)-related etiology (p = 0.001) and recurrent/persistent cardiogenic shock (p = 0.001). Conclusions: Iatrogenic etiology and neoplastic disease seem to be the most common indications for pericardiocentesis, while in-hospital mortality was particularly high in patients with spontaneous tamponade in the course of MI.
RESUMO
INTRODUCTION: Accidents and emergencies in the workplace account for a significant proportion of emergency calls worldwide. The specificity of these events is often associated with hazards at a given workplace. Patients do not always require hospitalization; therefore, the characteristics of events can only be determined from the perspective of emergency medical services teams. The aim of the study was to analyze calls and the course of emergency ambulance interventions to patients at their workplace. MATERIAL AND METHODS: The study was conducted based on a retrospective analysis of data contained in the medical records of the ambulance service from central Poland from 2015-2018. From all interventions (n = 155,993), 1601 calls to work were selected, and the urgency code, time of day and year, patients' sex, general condition, as well as diagnoses according to the International Classification of Diseases-ICD-10 and the method of ending the call were considered. RESULTS: The mean age of patients in the study group was 42.4 years (SD ± 13.5). The majority were men (n = 918; 57.3%). The number of calls increased in the autumn (n = 457; 28.5%) and in the morning (n = 609; 38.0%). The main reasons for the intervention were illnesses (ICD-10 group: R-'symptoms') and injuries (ICD-10 group: S, T-'injuries'). Calls at workplaces most often ended with the patient being transported to the hospital (78.8%), and least often with his death (0.8%). CONCLUSIONS: The patient profile in the workplace indicates middle-aged men who fall ill in the fall, requiring transport to the hospital and further diagnostics.

(1) Objective: Paramedics as a profession are a pillar of the State Medical Rescue system. The basic difference between a specialist and a basic team is the composition of members. The aim of the study was to benchmark the effectiveness of performing advanced resuscitation procedures undertaken by two- and three-person basic emergency medical teams in adults under simulated conditions. (2) Design: The research was observational. 200 two- and three-people basic emergency medical teams were analyzed during advanced resuscitation procedures, ALS (Advanced Life Support) in adults under simulated conditions. (3) Method: The study was carried out among professionally active and certified paramedics. It lasted over two years. The study took place under simulated conditions using prepared scenarios. (4) Results: In total, 463 people took part in the study. The analysis of the survey results indicates that the efficiency of three-person teams is superior to the activities performed by two-person teams. Three-person teams were quicker to perform rescue actions than two-person teams. The two-person teams were much quicker to assess the condition of victims than the three-person teams. The three-person teams were more likely to check an open airway. The three-person teams were more efficient in assessing the heart rhythm and current condition of victims. It was demonstrated that three-person teams were more effective during electrotherapy. The analysis demonstrated that three-person teams were significantly faster and more efficient in chest compressions. Three-person teams were less likely to use emergency airway techniques than two-person teams. The results indicate that three-person teams administered the first dose of adrenaline significantly faster than two-person teams. For the "call for help", the three-person teams were found to be more effective. (5) Conclusion: Paramedics in three-person teams work more effectively, make a proper assessment of heart rhythm and monitor when taking advanced actions. The quality of ventilation and BLS in both groups studied is insufficient. Numerous errors have been observed in two-person teams during pharmacotherapy.

The presence of a well-developed collateral circulation in the area of the artery responsible for the infarction improves the prognosis of patients and leads to a smaller area of infarction. One of the factors influencing the formation of collateral circulation is hypoxia, which induces angiogenesis and arteriogenesis, which in turn cause the formation of new vessels. The aim of this study was to assess the effect of endurance training conducted under normobaric hypoxia in patients after myocardial infarction at the level of exercise tolerance and hemodynamic parameters of the left ventricle. Thirty-five patients aged 43-74 (60.48 ± 4.36) years who underwent angioplasty with stent implantation were examined. The program included 21 training units lasting about 90 min. A statistically significant improvement in exercise tolerance assessed with the cardiopulmonary exercise test (CPET) was observed: test duration (p < 0.001), distance covered (p < 0.001), HRmax (p = 0.039), maximal systolic blood pressure (SBPmax) (p = 0.044), peak minute ventilation (VE) (p = 0.004) and breathing frequency (BF) (p = 0.044). Favorable changes in left ventricular hemodynamic parameters were found for left ventricular end-diastolic dimension LVEDD (p = 0.002), left ventricular end-systolic dimension LVESD (p = 0.015), left ventricular ejection fraction (LVEF) (p = 0.021), lateral e' (p < 0.001), septal e' (p = 0.001), and E/A (p = 0.047). Endurance training conducted in hypoxic conditions has a positive effect on exercise tolerance and the hemodynamic indicators of the left ventricle.

BACKGROUND/AIM: Haemostatic dressings for the uniformed and rescue services are an integral part of life-saving equipment for controlling post-traumatic haemorrhage. The aim of this study was to assess the influence of active constituent substances and materials of haemostatic dressings on muscle tissue and muscle regeneration after traumatic injury. MATERIALS AND METHODS: Three hemostatic dressing prototypes were analysed: OBR/G/S sponge: dressing material sponge made of Na-Ca chitosan/algal composite microfibers and nanofibers; OBR/MBT/S: tactic gauze modified with a polymer mixture of Na-Ca chitosan/algal composite microfibers and nanofibers, impregnated with a moderate amount of procoagulants (22.9 g/m2); and OBR/MS/S: seton gauze modified with a polymer mixture of Na-Ca chitosan/algal composite microfibers and nanofibers, impregnated with a moderate amount of procoagulants (18.0 g/m2), with chitosan (ChitoClearhqg 95) and sodium alginate (Protanal LF10/60 FT) as the coagulants. The experiment was conducted on 20 pigs which were euthanised 24 h, 7 or 14 days after wound dressing. Samples of porcine muscle tissue were subjected to qualitative histopathological analysis. RESULTS: Histopathological analysis of muscle tissues from the experimental pigs revealed that the application of modified seton (OBR/MS/S) produced the most satisfactory results. The observed changes were similar on all dates that samples were collected and in all experimental groups, and minor differences in their extent were observed between groups. Regenerative processes were most advanced, and retrograde changes were least apparent in animals treated with OBR/MS/S. CONCLUSION: Modified seton (OBR/MS/S) induced the least tissue reaction and was most effective in promoting tissue regeneration after injury.

BACKGROUND/AIM: Coagulopathy can develop when hemostatic dressings are used to stop massive bleeding, even in patients without prior history of clotting disorders. The selection of procoagulants, which effectively control bleeding and prevent disseminated intravascular coagulation (DIC) and thrombosis, is a significant challenge. The aim of this study was to evaluate the effect of two prototypes of haemostatic dressing in the porcine haemostatic system. MATERIALS AND METHODS: The total number of animals used in our experiments was 24. Group I: pigs were treated with the developed prototype of sponge dressing, made of Na-Ca chitosan/algal composite of microfibers and nanofibers. Group II: animals were treated with a seton gauze modified with a polymer mixture of Na-Ca chitosan/algal composite of microfibers and nanofibers. Group III: animals were treated with non-hemostatic dressing and this group was the control. Blood was sampled five times to determine changes in the coagulation and fibrinolytic profiles: before injury: i) at 1 h, ii) at 24 h, iii) at 7, and iv) at 14 days following injury. RESULTS: Significant changes were observed in the coagulation parameters, in the total numbers of white blood cells and platelets in groups I and II, compared to controls. CONCLUSION: The modified haemostatic dressings used in this study produced a strong procoagulant effect in pigs. This, together with high fibrinogen concentrations, which can cause DIC, require further studying.

BACKGROUND: Serious injuries accompanied by severe bleeding are life-threatening. Post-traumatic hemorrhage involves the risk of developing coagulopathy. Hemostatic dressings are widely used to minimize bleeding. The application of procoagulants in control of hemorrhage may lead to thrombosis or disseminated intravascular coagulation. The aim of this study was to evaluate the effect of hemostatic dressing prototypes on the porcine coagulation system. RESULTS: Fibrinogen and D-dimer concentrations were significantly higher in the experimental groups where hemostatic dressings were used in comparison with the control group. Considerable differences in antithrombin III activity and thrombin-antithrombin complex concentrations were also observed between groups. CONCLUSIONS: The hemostatic dressing comprising modified seton impregnated with 18.0 g/m2 of procoagulant was most effective in preserving the physiological equilibrium between fibrinogenesis and fibrinolysis.
