Histo-blood group A is a risk factor for severe COVID-19.

Objectives: Evaluate the impact of ABO histo-blood group type on COVID-19 severity.

Background: ABO histo-blood type has been associated with different outcomes in infectious diseases. It has also shown a higher proportion of type A patients with SARS-CoV-2.

Frailty Among Non-Elderly Patients Undergoing Cardiac Surgery.

Background: Usually viewed as a characteristic of old age, frailty may also occur in non-elderly people, primarily in those suffering from chronic disease. Frailty may increase operative risk.

Objectives: To determine the prevalence of frailty patients undergoing coronary artery bypass (CABG) and/or heart valve replacement or reconstruction and/or heart valve surgery, as well as the influence of frailty on postoperative outcomes.

An adaptation for exhaled breath condensate collection in rabbits.

Aim: To set up and test the feasibility of a handmade apparatus adapted for exhaled breath condensate (EBC) collection in medium-sized animals.

Materials And Methods: The apparatus was produced using an 18-mm thick u-shaped borosilicate glass. The u-shaped tube body is 25 cm in diameter, and the horizontal portions are 12 cm in diameter.

Key Points for Curbing Cardiopulmonary Bypass Inflammation.

Purpose: Cardiopulmonary bypass (CPB) procedures are thought to activate systemic inflammatory reaction syndrome (SIRS). Strategies to curb systemic inflammation have been previously described. However, none of them is adequate, since "curbing" the extent of the inflammatory response requires a multimodal approach.
