In the human resources of the university, the academic teachers has the essential role, perform duties of a teaching, research or organizational nature, depending on their membership in a certain group of positions. The legislator also stipulates that teaching may be carried out by other persons with appropriate competence and experience. Taking into account the forms of employment, it can be assumed that these persons will be connected with the university by a civil law contract, or they will perform activities within the framework of their business or conduct classes in connection with the status of a participant in a doctoral school. The analysis of the current legislation justifies the thesis that, despite the differences in the form of employment of academic teachers and other persons the convergence can be seen in the context of selection rigor and the impact on the assessment of the quality of education at the university.

Low operator and institutional volume are associated with poorer procedural and long-term clinical outcomes in the general population of patients treated with percutaneous coronary interventions (PCI).To assess the relationship between operator experience and procedural outcomes of patients treated with PCI and rotational atherectomy (RA).Data for conducting the current analysis were obtained from the national registry of percutaneous coronary interventions (ORPKI) maintained in cooperation with the Association of Cardiovascular Interventions (AISN) of the Polish Cardiac Society. The study covers data from January 2014 to December 2020.During the investigated period, there were 162 active CathLabs, at which 747,033 PCI procedures were performed by 851 operators (377 RA operators [44.3%]). Of those, 5188 were PCI with RA procedures; average 30 ± 61 per site/7 years (Me: 3; Q1-Q3: 0-31); 6 ± 18 per operator/7 years (Me: 0; Q1-Q3: 0-3). Considering the number of RA procedures annually performed by individual operators during the analyzed 7 years, the first quartile totaled (Q1: =2.57), the second (Q2: =5.57), and the third (Q3: =11.57), while the fourth quartile was (Q4: 11.57). The maximum number of procedures was 39.86 annually per operator. We demonstrated, through a nonlinear relationship with annualized operator volume and risk-adjusted, that operators performing more PCI with RA per year (fourth quartile) have a lower number of the overall periprocedural complications (p = 0.019).High-volume RA operators are related to lower overall periprocedural complication occurrence in patients treated with RA in comparison to low-volume operators.

Employment of an academic teacher at a basic and additional working place in one of the essential normative constructions regulated under the higher education act. Control of additional employment of academic teachers is one of exceptions from the constitutional principle of the freedom of work. This mechanism in the employment relationship of academic teachers is justified first of all by the role and tasks of the higher education system in the activities of the state. Additionally there should also be mentioned the protection of interests of an employer and the specific character of hiring academic teachers. Such criteria should also be used by a vice-chancellor when giving his/her consent to their employment at an additional working place.

A subjective change of the employment relationship by the employer is subject to the regulation of Art. 231 of the labour code. The norm has got a universal character and its application to the employment in an institution of higher education requires taking into account the specificity of two aspects. Firstly, it is the matter of a workplace possessed by an institution of higher education as the employer. Secondly, the higher education act introduces mechanisms which can be defined as characteristic to this form of transfer of a workplace. In case of the former it is important whether an institution of higher education is public or non-public. Subjective transformation of the employment relationship in institutions of higher education should also require consideration of the protection of stability of employment relationship of academic teachers.

Patients undergoing percutaneous coronary interventions (PCI) with rotational atherectomy (RA) have massively calcified coronary arteries and their prognosis differs between sexes.The aim of the study was to evaluate the trends in the percentage of sexes in the subsequent years, to compare demographic characteristics between men and women, and to identify factors associated with the risk of periprocedural complications and death.We analyzed data on 751 113 patients treated with PCI between 2014 and 2020 from the Polish National Registry of Percutaneous Coronary Interventions (ORPKI). We extracted data on 5 177 (0.7%) patients treated with RA of whom 3 552 (68.6%) were men. To determine risk factors of periprocedural complications and death, a multivariable analysis was performed.The proportion of PCIs involving RA increased between 2014 and 2020 (P0.001). Almost twice as many RA procedures were performed on men (68.55%), and that proportion did not change in the following years. The female patients were older (75.2 [8.3] vs. 70.5 [9.2] years; P0.001). When considering periprocedural complications, their overall rate (3.45% vs. 2.31%; P = 0.01) and death rate (0.68% vs. 0.17%; P = 0.006) were greater among women. Also, via multivariable analysis, female sex was found to be a risk factor for greater periprocedural mortality (P = 0.02) and overall complication rate (P = 0.007).The majority of patients treated with RA are men and sex-related distribution was stable during the analyzed period. Female sex is a risk factor for greater periprocedural complications and mortality in patients treated with RA.

Background: The aim of this study was to determine the influence of acute exposure to air pollutants on patients’ profile, short- and mid-term outcomes of hospitalized patients with coronary artery disease (CAD) treated with coronary angioplasty. Methods: Out of 19,582 patients of the TERCET Registry, 7521 patients living in the Upper Silesia and Zaglebie Metropolis were included. The study population was divided into two groups according to the diagnosis of chronic (CCS) or acute coronary syndromes (ACS). Data on 24-h average concentrations of particulate matter with aerodynamic diameter 2), nitrogen monoxide (NO), nitrogen dioxide (NO2), and ozone (O3) were obtained from eight environmental monitoring stations. Results: No significant association between pollutants’ concentration with baseline characteristic and in-hospital outcomes was observed. In the ACS group at 30 days, exceeding the 3rd quartile of PM10 was associated with almost 2-fold increased risk of adverse events and more than 3-fold increased risk of death. Exceeding the 3rd quartile of SO2 was connected with more than 8-fold increased risk of death at 30 days. In the CCS group, exceeding the 3rd quartile of SO2 was linked to almost 2,5-fold increased risk of 12-month death. Conclusions: The acute increase in air pollutants’ concentrations affect short- and mid-term prognosis in patients with CAD.

To functionalize and improve the biocompatibility of the surface of a medical implant made of NiTi shape memory alloy and used in practice, a clamp, multifunctional layers composed of amorphous TiO2 interlayer, and a hydroxyapatite coating were produced. Electrophoresis, as an efficient method of surface modification, resulted in the formation of a uniform coating under a voltage of 60 V and deposition time of 30 s over the entire volume of the implant. The applied heat treatment (800 °C/2 h) let toa dense, crack-free, well-adhered HAp coating with a thickness of ca. 1.5 μm. and a high crack resistance to deformation associated with the induction of the shape memory effect in the in the deformation range similar to the real implant work after implantation. Moreover, the obtained coating featured a hydrophilic (CA = 59.4 ± 0.3°) and high biocompatibility.

Background Patients undergoing percutaneous coronary intervention (PCI) procedures using rotational atherectomy (RA) are a special group of patients characterised by the presence of massive calcifications in the coronary arteries. Due to a significant increase regarding the frequency of these procedures in recent years and the distinctiveness of this narrow group of patients among all patients undergoing PCIs, we have characterised the group according to gender. Aims The aim of analysis was to assess the gender percentage share in following years and differences between both groups of Polish patients undergoing PCI with rotational RA between 2014 and 2020. Methods Based on the Polish National Registry of Percutaneous Coronary Interventions (ORPKI), we analysed 751,113 patients treated with PCI between 2014 and 2020. Then, we extracted 5,177 (0.7%) treated with PCI and RA, 3,552 of them (68.6%) were males. Selected indices among the two groups were compared using the t-test for continuous variables, the χ2 test or the likelihood-ratio test for nominal variables where appropriate. To compare means of samples in the following years, one-way ANOVA test was used. Results The results of the study indicate an upward RA tendency in successive years (p Females were significantly older in comparison to males [75.2±8.3 vs. 70.5±9.2, p Conclusion The percentage of RA among overall PCIs has been still growing in recent years in Poland. The majority of patients treated with RA are men. Gender distribution did not change significantly among patients treated with PCI and RA during the analysed period of time.
