Assessment of the Severity of COVID-19 on the Basis of Examination and Laboratory Diagnostics in Relation to Computed Tomography Imagery of Patients Hospitalised Due to COVID-19-Single-Centre Study.

From the moment the SARS-CoV-2 virus was identified in December 2019, the COVID-19 disease spread around the world, causing an increase in hospitalisations and deaths. From the beginning of the pandemic, scientists tried to determine the major cause that led to patient deaths. In this paper, the background to creating a research model was diagnostic problems related to early assessment of the degree of damage to the lungs in patients with COVID-19.

Job satisfaction and social identification among paramedics in southern Poland.

Introduction: Job satisfaction, based on professional and non-professional factors and individual characteristics of employees, is an important element influencing both the quality of care provided and employee turnover.

Material And Method: The study included 137 paramedics employed in field teams and hospital emergency departments. The Job Satisfaction Scale (SSP), the Minnesota Job Satisfaction Questionnaire (MSQ), the Utrecht Work Engagement Scale (UWES), and the Three Dimensional Strength of Group Identification Scale (TSIG) were used to collect the data.

Opioidergic conditioning of the human heart muscle in nitric oxide-dependent mechanism.

Background: Opioidergic conditioning is well documented to trigger cardioprotection against ischemia/ reperfusion (I/R) injury. Previous studies on animal models have suggested that nitric oxide (NO) mediates the beneficial effect of opioids, but the role of NO in humans seems to be controversial.

Objectives: The aim of the study was to assess the influence of NO modulators on opioid-induced cardioprotection in the human myocardium.

Ischemic conditioning of human heart muscle depends on opioid-receptor system.

Background: Despite progress in the invasive treatment of ischemic heart disease, the ability to limit ischemia-reperfusion (I/R) injury remains largely unrealized. Ischemic pre-conditioning (IPC) and post-conditioning (POC) induce the protective mechanisms of resistance against I/R injury. Stimulation of opioid receptors mimic the protective effect of IPC or POC in an animal models.
