Awake prone positioning and ventilation distribution as assessed by electric impedance tomography in patients with non-COVID-19 acute hypoxemic respiratory failure: A prospective physiology study.

Background: Awake prone positioning (APP) can reportedly reduce the need for intubation and help improve prognosis of patients with acute hypoxemic respiratory failure (AHRF) infected with COVID-19. However, its physiological mechanism remains unclear. In this study, we evaluated the effect of APP on lung ventilation in patients with moderate-to-severe AHRF to better understand the effects on ventilation distribution and to prevent intubation in non-intubated patients.

However, the role of the gut microbiota in the foreign body response (FBR) and fibrosis around medical implants is largely unexplored. To investigate this connection, we perturbed the homeostasis of the murine gut microbiota via enterotoxigenic (ETBF) infection and implanted the synthetic polymer polycaprolactone (PCL) into a distal muscle injury.

To better understand the contribution of tumor genotype to immunosurveillance, we generated and validated lentiviral vectors that create an epi-allelic series of increasingly immunogenic neoantigens. This vector system is compatible with autochthonous Cre-regulated cancer models, CRISPR/Cas9-mediated somatic genome editing, and tumor barcoding.

Department of Cardiology, Respiratory Medicine and Intensive Care, University Hospital Augsburg, Augsburg, Germany.
Background: Chronic obstructive pulmonary disease (COPD) affects breathing, speech production, and coughing. We evaluated a machine learning analysis of speech for classifying the disease severity of COPD.
Methods: In this single centre study, non-consecutive COPD patients were prospectively recruited for comparing their speech characteristics during and after an acute COPD exacerbation.
Residing in areas with high residential greenspace is associated with increased COPD risk and decreased lung function of adults in eastern China.

Department of Preventive Medicine, Shantou University Medical College, Shantou, Guangdong 515041, China. Electronic address:
Background: Evidence for a relation between residential greenspace and respiratory health is scarce and controversial.
Objectives: The purpose of this study was to explore the association between residential greenspace and its interaction with particulate matter (PM) and risk of chronic obstructive pulmonary disease (COPD) and lung function.
Methods: A total of 3,759 adults were recruited from Wenzhou in this study.
