[1]. In this cross-sectional study, they reported that COPD patients, hospitalised with an acute exacerbation episode, exhibited significant self-reported and clinically screened swallowing dysfunction. These data are interesting, as they confirm previous physiopathological studies, which could also be of interest to the readers of ERJ Open Research. They aimed to understand the underlying mechanisms that may predispose COPD patients to pneumonia aspiration and exacerbation of COPD [2, 3], and to propose possible solutions to improve vulnerability to aspiration [4]. However, evidence is already available in the literature on these topics.This correspondence deals with physiopathological studies that aimed to understand the underlying mechanisms of breathing–swallowing interaction https://bit.ly/3BKAwx3 ER -
