Obesity is a complex and non-communicable disease with a pandemic entity. Currently, multiple causes can lead to obesity, and it is not always easy to create a direct relationship between physical inactivity, poor quality of nutrients consumed, and calculation of excess calories. Among the associated comorbidities, obesity creates a dysfunctional environment of respiratory rhythms at the central and peripheral levels, with functional, morphological, and phenotypic alteration of the diaphragm muscle.

Pyroptosis plays an important role in attracting innate immune cells to eliminate infected niches. Our study focuses on how influenza A virus (IAV) infection triggers pyroptosis in respiratory epithelial cells. Here, we report that IAV infection induces pyroptosis in a human and murine airway epithelial cell line.

Department of Respiratory Medicine and Allergology, COPD Center, Sahlgrenska University Hospital and Department of Internal Medicine and Clinical Nutrition, Institute of Medicine, Sahlgrenska Academy, University of Gothenburg, Gothenburg, Sweden.
Background: Remote patient monitoring (RPM) has been evaluated in COPD, but with varying results. We aimed to evaluate whether a tablet system that monitors disease-related parameters in patients with COPD could influence physical and mental health-related quality of life, compared with usual care (UC).
Methods: 70 patients with Global Initiative for Chronic Obstructive Lung Disease (GOLD) group D COPD (61% women, aged 71±8 years, forced expiratory volume in 1 s % predicted 41±13%, COPD Assessment Test (CAT) 19±7 points) were recruited at the COPD centre in Gothenburg, Sweden, and randomised to a tablet-based RPM system or UC for a 26-week period, after which they crossed over to the alternative management for another 26 weeks.
Inhaled alpha-1 antitrypsin (AAT) restores lower respiratory tract protease-antiprotease homoeostasis and reduces inflammation in AAT-deficient individuals: a randomised phase 2 study.
ERJ Open Res
January 2025
Kamada Ltd., Rehovot, Israel.
Background: Alpha-1 antitrypsin (AAT)-deficient individuals have a greater risk for developing COPD than individuals with normal AAT levels.
Methods: This was a double-blind, randomised, parallel group, placebo-controlled trial to examine the safety and tolerability of "Kamada-AAT for Inhalation" (inhaled AAT) in subjects with AAT deficiency, and to explore its effect on AAT and biomarkers in the lung epithelial lining fluid (ELF). 36 patients with severe AAT deficiency were randomised 2:1 to receive 80 mg or 160 mg inhaled AAT or placebo once daily for 12 weeks.
Utilization of High-Flow Nasal Cannulas in Pediatric Critical Care: A Single-Center Experience.
Cureus
December 2024
Pediatric Intensive Care Unit, King Fahad Medical City, Riyadh, SAU.
Background: High-flow nasal cannula (HFNC) therapy has developed as a valuable tool for respiratory support in pediatric critical care. It offers an intermediate level of support between traditional low-flow oxygen and non-invasive ventilation (NIV). Studies suggest its effectiveness in improving oxygen delivery, work of breathing, and secretion clearance.
