- Description: It has long been recognized that the structure of arteries throughout the vascular tree is not uniform. Notably, the media of large proximal (central) vessels contains relatively much greater amounts of elastin and elastic lamellae than smaller, more distal (peripheral) arteries; the converse is true of vascular smooth muscle cells. Under physiological conditions, the greater elasticity of central arteries compared with more muscular peripheral arteries allows conversion of the pulsatile nature of ventricular ejection into a relatively steady flow of blood at the distal end of the arterial system, conferring protection from pulsatile energy [1,2]. Furthermore, these differences in impedance can generate partial wave reflections, which arrive in the aorta during diastole, boosting diastolic blood pressure and augmenting coronary perfusion pressure [3].

- Description: The detection of antinuclear autoantibody (ANA) is dependent on many factors and varies between the populations. The aim of the study was first to assess the prevalence of ANA in the Polish adult population depending on age, sex and the cutoff threshold used for the results obtained. Second, we estimated the occurrence of individual types of ANA-staining patterns. We tested 1731 patient samples using commercially available IIFA using two cutoff thresholds of 1:100 and 1:160. We found ANA in 260 participants (15.0%), but the percentage of positive results strongly depended on the cutoff level. For a cutoff threshold 1:100, the positive population was 19.5% and for the 1:160 cutoff threshold, it was 11.7%. The most prevalent ANA-staining pattern was AC-2 Dense Fine speckled (50%), followed by AC-21 Reticular/AMA (14.38%) ANA more common in women (72%); 64% of ANA-positive patients were over 50 years of age. ANA prevalence in the Polish population is at a level observed in other highly developed countries and is more prevalent in women and elderly individuals. To reduce the number of positive results released, we suggest that Polish laboratories should set 1:160 as the cutoff threshold. © 2021, The Author(s). **Please note that there are multiple authors for this article therefore only the name of the first 30 including Federation University Australia affiliate “Fadi Charchar" is provided in this record**
