Airway pressure release ventilation (APRV) versus pressure support ventilation (PSV)-A prospective intervention trial comparing haemodynamic parameters in intensive care patients.

Background And Aim: Assisted mechanical ventilation may alter the pressure profile in the thorax compared to normal breathing, which can affect the blood flow to and from the heart. Studies suggest that in patients with severe lung disease, airway pressure release ventilation (APRV) may be haemodynamically beneficial compared to other ventilator settings. The primary aim of this study was to investigate if APRV affects cardiac index in intubated intensive care patients without severe lung disease when compared to pressure support ventilation (PSV).

Galectin-2 3279TT variant protects against the lymphotoxin-alpha 252GG genotype associated ischaemic stroke.

Objective: The galectin-2 protein is presumed to play a regulatory role in the intracellular trafficking of the lymphotoxin-alpha (LTA) cytokine. LTA is a pro-inflammatory factor, its 252GG homozygote variant is considered as a susceptibility factor for arteriosclerosis and cardiovascular diseases. By contrast, the galectin-2-encoding gene LGALS2 3279TT homozygote variant has been demonstrated to exert protection against myocardial infarction by reducing the transcriptional level of galectin-2, thereby leading to a reduced extracellular secretion of LTA.
