Patient-specific premorbidity, age, and sex are significant heterogeneous factors that influence the severe manifestation of lung diseases, including COVID-19 fibrosis. The renin-angiotensin system (RAS) plays a prominent role in regulating the effects of these factors. Recent evidence shows patient-specific alterations of RAS peptide homeostasis concentrations with premorbidity and the expression level of angiotensin-converting enzyme 2 (ACE2) during COVID-19.

Division of Otolaryngology-Head & Neck Surgery, Children's National Medical Center, Washington, D.C, USA. Electronic address:
Objectives: To examine safety and efficacy of very young patients under the age of six who underwent endoscopic sinus surgery (ESS) at our institution for the indications of either complicated acute rhinosinusitis (ARS) or chronic rhinosinusitis (CRS).
Methods: Retrospective cohort review of patients under six years old who underwent ESS for sinonasal pathology between 2016 and 2023 at a freestanding pediatric hospital. Age, sex, weight, diagnosis, laterality of disease, medications, types and number of surgical interventions, usage of image guidance, and outcomes were obtained from the medical record.
Macrophage STING signaling promotes fibrosis in benign airway stenosis via an IL6-STAT3 pathway.
Nat Commun
January 2025
Department of Respiratory and Critical Care Medicine, The First Affiliated Hospital of Naval Medical University, Shanghai, China.
Acute and chronic inflammation are important pathologies of benign airway stenosis (BAS) fibrosis, which is a frequent complication of critically ill patients. cGAS-STING signalling has an important role in inflammation and fibrosis, yet the function of STING in BAS remains unclear. Here we demonstrate using scRNA sequencing that cGAS‒STING signalling is involved in BAS, which is accompanied by increased dsDNA, expression and activation of STING.

Department of Psychiatry, University of Florida, Gainesville, FL, USA. Electronic address:
Tobacco use disorder is a chronic disorder that affects more than one billion people worldwide and causes the death of millions each year. The rewarding properties of nicotine are critical for the initiation of smoking. Previous research has shown that the activation of glucocorticoid receptors (GRs) plays a role in nicotine self-administration in rats.
