Opis: This article aims to analyse significant differences in four constructs: occupational stress, job satisfaction, work engagement, and work productivity among employees before and after the COVID-19 pandemic. The purpose of the paper is to develop a multidimensional model with these four constructs and analyse the differences in the strength of their effects on the model across two intersectional times: before the COVID-19 pandemic and during the COVID-19 pandemic. The research was implemented on a sample of 885 employees in Slovenian organisations. During COVID-19, Slovenia had one of the strictest lockdowns. Based on the research, we can confirm significant differences in the four analysed constructs among employees before COVID-19 and during COVID-19. Based on the results, we can confirm that occupational stress had a more negative effect on job satisfaction and work engagement during COVID-19 than before prior to it. Our research and conclusions highlight the measures with which organisations can reduce the problem of occupational stress and with which organisations can increase job satisfaction, work engagement and work productivity among employees during COVID-19. Based on this, organisations may be able to build a more supportive work environment during, and after, COVID-19.

Opis: The organizational culture is a significant construct in a time of change during the organizational transition, and it plays an important role in achieving goals of social responsibilities, which is an important part of sustainability. The literature shows the gap of socially responsible transfer of organizational culture with the impact on employee’s well-being. The cultural changes of the organization during the transition are particularly in connection with the impact on internal communication where organizational culture presents a part of values, norms, and ethics, which influences successfully implemented changes and in such a way has an influence on the stress and work satisfaction. The main purpose of the presented study is the development of the model of socially responsible transfer of organizational culture to the foreign subsidiaries on a basis of adjusted internal communication, which reduces stress and increases work satisfaction. Impacts of organizational culture on internal communication, stress, and work satisfaction are clearly presented, as well as inter-related impacts of the constructs concerning national culture, leadership, and organizational knowledge. Thus, the new holistic model of socially responsible transfer of the parent organization culture to foreign subsidiaries clearly defines steps of organizational culture, internal communication, stress management, and work satisfaction. Managerial implications are discussed.

Opis: Cardiac surgery-associated acute kidney injury (CS-AKI) is a major complication associated with increased morbidity and mortality. There are multiple diagnostic criteria for CS-AKI. Despite many new investigations available for improved AKI diagnostics, creatinine and urea remain the cornerstone of diagnostics in everyday clinical practice. There are three major pathophysiological mechanisms that contribute to kidney injury, i.e. renal hypoperfusion, inflammation with oxidative stress, and use of nephrotoxic agents. Some risk factors have been identified that can be modified during the course of treatment (use of nephrotoxic agents, duration of cardiopulmonary bypass, type of extracorporeal circulation, postoperative low cardiac output or hypotension). The aim of AKI prevention should always be to prevent aggravation of renal failure and, if possible, to avoid progression to renal replacement therapy, which in turn brings worse long-term outcomes.

Opis: Cardiopulmonary resuscitation (CPR) is one of the most stressful situations in emergency medicine. Nurses involved in performing basic and advanced resuscitation procedures are therefore exposed to a certain amount of stress. The purpose of this study was to determine the stressors and the level of stress experienced by nurses during resuscitation. A cross-sectional quantitative study was done. The sample consisted of 457 nurses who worked in emergency units. First demographic data were collected, followed by a questionnaire regarding the effect of different situations that occur during and after resuscitation on nurses including Post-Code Stress Scale questionnaire. The most disturbing situations for respondents were resuscitation of young person (MV = 3.7, SD = 1.4), when they fail to establish an intravenous pathway (MV = 3.5, SD = 1.4), chaotic situation during resuscitation (MV = 3.4, SD = 1.4) and making decision about termination of resuscitation (MV = 3.1, SD = 1.5). Research has shown that nurses are exposed to a certain amount of stress during resuscitation, but most of them manage to compensate for stress effectively.

Opis: Rationale: Atrial fibrillation (AF) and heart failure often coexist, but their interaction is poorly understood. Clinical data indicate that the arrhythmic component of AF may contribute to left ventricular (LV) dysfunction. Objective: This study investigates the effects and molecular mechanisms of AF on the human LV. Methods and results: Ventricular myocardium from patients with aortic stenosis and preserved LV function with sinus rhythm or rate-controlled AF was studied. LV myocardium from patients with sinus rhythm and patients with AF showed no differences in fibrosis. In functional studies, systolic Ca2+ transient amplitude of LV cardiomyocytes was reduced in patients with AF, while diastolic Ca2+ levels and Ca2+ transient kinetics were not statistically different. These results were confirmed in LV cardiomyocytes from nonfailing donors with sinus rhythm or AF. Moreover, normofrequent AF was simulated in vitro using arrhythmic or rhythmic pacing (both at 60 bpm). After 24 hours of AF-simulation, human LV cardiomyocytes from nonfailing donors showed an impaired Ca2+ transient amplitude. For a standardized investigation of AF-simulation, human iPSC-cardiomyocytes were tested. Seven days of AF-simulation caused reduced systolic Ca2+ transient amplitude and sarcoplasmic reticulum Ca2+ load likely because of an increased diastolic sarcoplasmic reticulum Ca2+ leak. Moreover, cytosolic Na+ concentration was elevated and action potential duration was prolonged after AF-simulation. We detected an increased late Na+ current as a potential trigger for the detrimentally altered Ca2+/Na+-interplay. Mechanistically, reactive oxygen species were higher in the LV of patients with AF. CaMKII (Ca2+/calmodulin-dependent protein kinase IIδc) was found to be more oxidized at Met281/282 in the LV of patients with AF leading to an increased CaMKII activity and consequent increased RyR2 phosphorylation. CaMKII inhibition and ROS scavenging ameliorated impaired systolic Ca2+ handling after AF-simulation. Conclusions: AF causes distinct functional and molecular remodeling of the human LV. This translational study provides the first mechanistic characterization and the potential negative impact of AF in the absence of tachycardia on the human ventricle.
