Opis:
The heterogeneous population of patients affected by trauma is extremely difficult to systematize. This is due to the diversity of mechanisms of injury, the nature and severity of the injury and the population, which relate to injuries, diverse in terms of gender, age, presence of comorbidities that make up the final severity of the injury and a certain degree of danger to life. The aim of the study was to develop a universal method to assess the severity of injury and loss of life resulting from their consequences, using the parameters available in the Polish administrative databases, a similar diagnostic efficacy as other used scales to assess the severity of damage. Material and methods. The study analyzed a group of 92 463 patients hospitalized due to injuries sustained as a result of injuries in all hospitals of the Lublin region in 2003-2005. Developed catalogs risk factors, reference to the population of the Lublin province. Results. Developed five models predictive of injury severity scale counterparts, which include different combinations of risk factors associated with the type of injury, age of the patient and the mechanism of injury that have been evaluated for their diagnostic efficacy in differentiating the expected outcomes. Prediction model have the best diagnostic efficacy AUROC 0.9615, SE 0.0025 and 95% CI 0,9565-0,9665, hereinafter referred to as Life Hazard Ratio (LHR), which has a similarly high diagnostic efficacy as the other, examined in the work of the rock assess the severity of damage AUROC 0.9585, SE 0.0368, 95% CI0 0.8849-1. Conclusions. 1. The proposed method of use of the International Classification ICD-10 allows the use of regional administrative databases to conduct detailed analyzes of population and monitor trends in the epidemiology of injuries. 2. Developed Life Hazard Ratio (LHR)is a universal method for the objective evaluation of the severity of injuries and the associated risk of life-threatening, can also conduct population studies. 3. LHR has a comparable rate of diagnostic efficacy as other commonly used scales assessing the severity of the injury.

Opis:
Introduction. The high requirements in terms of physical fitness of hockey players may be a factor predisposing to injuries. The purpose of the study was to determine the functional limitations of the locomotor system of children practicing ice hockey. Materials and met hods. 104 children took part in the study, including 16 girls and 88 boys, divided into two groups. The first group consisted of children practicing hockey (n=38). The second group consisted of children who do not practice hockey (n=66). The research tool was the FMS test consisting of seven movement activities graded on a 0 - 3 scale. The Mann - Whitney U test was used to evaluate the differences between particular groups, and the Wilcoxon’s test was used to evaluate the differences between the sides. The rela tionships between the variables were established based on the rho Spearmann correlation. The minimal statistical significance was set at p ≤ 0.05. Results. The boys practicing hockey obtained a significantly higher total result than the boys who are not hock ey players (p=0.008). The girls practicing hockey obtained a result close to their peers who do not play hockey. A significant positive correlation was observed between the age of the players and the result obtained in the FMS test in the group of hockey p layers (r=0.77; p<0.001), and between the training experience and the result of the test (r=0.49; p<0.01). Conclusion. The players obtained a significantly statistically higher result in the FMS test, which may indicate a higher level of functional fitness , resulting from a rational training and the acceleration of motor development.

Aims. The aim of the study was to assess the usefulness of TNF-α and CK-18 as diagnostic markers of alcoholic liver cirrhosis. Additionally, the effects of the stage of liver cirrhosis on concentrations of TNF-α and CK-18, as well as their correlation, were evaluated. Materials and method. Sixty-two patients with alcoholic liver cirrhosis treated in various hospitals were randomly enrolled. The stage of cirrhosis was assessed according to the Child-Turcotte-Pugh scoring system. The control group consisted of 31 healthy people without liver disease. Concentrations of TNF-α and cytokeratin-18 in blood plasma of patients and controls were measured using the sandwich enzyme immunoassay technique, with commercially available quantitative ELISA test kits. Results. The concentration of CK-18 was statistically higher in patients with alcoholic liver cirrhosis, compared to the control group. The concentration of TNF-α was significantly higher in patients with alcoholic liver cirrhosis, compared to the control group. Higher concentrations of TNF-α were found only in patients with stage C and B alcoholic liver cirrhosis, compared to healthy persons. Conclusions. The levels of TNF-α and total CK-18 were higher in patients with alcoholic liver cirrhosis than in healthy individuals. No correlation was found between the level of CK-18 and stage of liver cirrhosis.

Opis:
The paper presents the results pertaining to an analysis on the influence of technological parameters of pneumatic shot peening technology on the selected properties of a surface layer of butt joints made with Friction stir weld‑ ing (FSW) method. Butt joints made of two 2024‑T3 aluminum alloy sheets with the thickness of 1 mm were shot peened with glass beads. The experiments were carried out according to the statistical 3‑level completed plan PS/DC 32 . The technological parameters were changed in the range: pressure p = 0.4–0.6 MPa and peening time t = 1–3 min. As a result of the conducted research, adequate equations describing the effect of the analyzed parameters on the surface roughness were obtained. Shot peening with glass beads significantly reduced the sur‑ face roughness from Ra = 5.2 µm to Ra = 1.42 µm. This treatment provides high compressive residual stresses and the increase of the surface layer hardness. The results show that shot peening is a highly efficient and cost‑effective mechanical treatment used for improving the mechanical properties of the butt joints made with the FSW method.

Opis:
This article presents the influence of the brushing process on residual stress and surface roughness of EN AW-2024-T3 aluminum alloy joints welded using the Friction Stir Welding (FSW) method. Butt joints with thicknesses of 2 mm were brushing with using ceramic brush. The aim of the study was to find optimal parameters of the brushing process, which would significantly improve the functional properties of welded joints. The experiments were carried out in two steps. In the first stage of the research, the feed rate was changed in the range f = 40 ÷ 120 mm / min with a constant brushing depth d = 0.5 mm. The roughness decreased from Sa = 5.285 µm for the specimen after welding to Sa = 2.460 µm for the f = 120 mm/min and d = 0.5 mm. The change in the parameters of the brushing process did not have a significant impact on the state of residual stresses. Hence, in the second step, the brushing depth was increased in steps of 0.1 mm. The best properties were obtained for f = 120 mm / min and d = 0.6 mm (variant 6A), where roughness was Sa = 0.443 µm and compressive stresses σ = -118 MPa.
