Randomized Controlled Trial
A one-year weight management programme for difficult-to-treat asthma with obesity: a randomised controlled study.
Obesity-associated asthma results in increased morbidity and mortality. We report 1-year asthma outcomes with a weight management regimen, the Counterweight-Plus Programme (CWP), compared with usual care (UC) in a single-center, randomized controlled trial in patients with difficult-to-treat asthma and obesity. ⋯ In this study, the use of a dietitian-supported weight management program resulted in sustained weight loss and is a potential treatment for obesity in asthma. The CWP resulted in a higher proportion achieving MCID improvements in AQLQ compared with UC. Within-group differences in AQLQ and exacerbation frequency suggest potential with the CWP. These encouraging signals justify a larger sample study to further assess asthma-related outcomes.

Randomized Controlled Trial
Plasminogen Degradation by Neutrophil Elastase in Pleural Infection, Not High Plasminogen Activator Inhibitor-1 (PAI-1), is the Cause of Intrapleural Lytic Failure.
Complex pleural space infections often require treatment with multiple doses of intrapleural tissue plasminogen activator (tPA) and deoxyribonuclease, with treatment failure frequently necessitating surgery. Pleural infections are rich in neutrophils, and neutrophil elastase degrades plasminogen, the target substrate of tPA, that is required to generate fibrinolysis. We hypothesized that pleural fluid from patients with pleural space infection would show high elastase activity, evidence of inflammatory plasminogen degradation, and low fibrinolytic potential in response to tPA that could be rescued with plasminogen supplementation. ⋯ Our findings suggest that inflammatory plasminogen deficiency, not high PAI-1 activity, is a significant contributor to intrapleural fibrinolytic failure.

Randomized Controlled Trial
The responsiveness of different exercise tests in Chronic Obstructive Pulmonary Disease: a randomised controlled trial.
COPD is characterized by reduced exercise tolerance, and improving physical performance is an important therapeutic goal. A variety of exercise tests are commonly used to assess exercise tolerance, including laboratory and field-based tests. The responsiveness of these various tests to common COPD interventions is yet to be compared, but the results may inform test selection in clinical and research settings. ⋯ International Standard Randomised Controlled Trial Number (ISRCTN): No. 64759523; URL: https://www.isrctn.com/ISRCTN64759523.

Randomized Controlled Trial Multicenter Study
Nocturnal Cardiac Arrhythmias in Heart Failure with Obstructive and Central Sleep Apnea.
Both obstructive and central sleep apnea (CSA) may contribute to nocturnal cardiac arrhythmias (NCAs). Data are scarce regarding the prevalence of clinically important nocturnal atrial and ventricular arrythmias in patients with heart failure with reduced ejection fraction (HFrEF) and OSA or CSA. ⋯ gov.

Randomized Controlled Trial Multicenter Study
GRAvity- versus Wall suction-drIven large volume Thoracentesis: a rAndomized controlled Study (GRAWITAS study).
Prior studies have found no differences in procedural chest discomfort for patients undergoing manual syringe aspiration or drainage with gravity after thoracentesis. However, whether gravity drainage could protect against chest pain due to the larger negative-pressure gradient generated by wall suction has not been investigated. ⋯ gov.
