Lung health after covid . . . and other stories

Long term effects of covid-19 pneumoniaPersisting structural lung abnormalities after covid-19 pneumonia seem to be infrequent. Eighty four people who had survived covid-19 pneumonia severe enough to require hospitalisation, but not severe enough to need intubation or mechanical ventilation, were investigated using high resolution computed tomography scanning a year later. Lung abnormalities had completely resolved in 78 of the participants (Radiology doi:10.1148/radiol.220019).Renal denervationRandomised controlled trials have shown that renal denervation carried out by radiofrequency ablation via a catheter induces a modest fall in blood pressure. A registry study suggests that the procedure leads to a useful reduction in the risk of cardiovascular events. Among 3000 people with hypertension inadequately controlled by medication, who were treated with renal denervation, there were sustained reductions in systolic blood pressure and fewer major cardiovascular events over 36 months of follow-up (J Am Coll Cardiol doi:10.1016/j.jacc.2022.08.802).PACE labelsTen worksite cafeterias in England were randomised in the…
