Lung abscess: Clinical characteristics of 222 Danish patients diagnosed from 2016 to 2021.

Introduction: Lung abscess (LA) is a serious respiratory infection often followed by several weeks of antibiotic treatment. This study described the clinical presentation of LA, treatment duration and mortality in a contemporary Danish population.

Methods: In a retrospective multicenter cohort study at four Danish hospitals, patients diagnosed with LA were identified using the International Classification of Diseases and Related Health Problems 10th revision (ICD-10) between 2016 and 2021.

Nocturnal blood pressure decrease in patients with chronic kidney disease and in healthy controls - significance of obstructive sleep apnea and renal function.

Background: Chronic kidney disease (CKD) is often associated with a blunted nocturnal BP decrease and OSA. However, it is not fully clear whether a relationship exists between reduction in renal function and obstructive sleep apnea (OSA) on the one hand and relative nocturnal BP decrease in CKD patients on the other. The aim of this study was to investigate the association between nocturnal BP decrease and renal function, the degree of OSA, vasoactive hormones, and renal sodium handling in CKD3-4 patients and healthy age-matched controls.
