Coronavirus disease-19 (COVID-19) causes mild to moderate illness in most patients but in some cases a severe illness may manifest. Such patients usually present with hypoxaemic respiratory failure due to acute lung injury caused by a viral infection and host-mediated cytokine storm. The characteristic radiographic findings are ground-glass opacities with consolidation in posterior basal areas of bilateral lungs and rarely pneumothorax (PTX) and pneumomediastinum (PM). The incidence of these findings was notably higher in the second wave of the pandemic in India in 2021 as compared to the first wave in 2020. The etiopathogenesis of this life-threatening condition can be due to Macklin phenomenon post-cytokine-mediated diffuse alveolar injury, patient self-inflicted lung injury (P-SILI), and barotrauma in mechanically ventilated patients. The presence of pneumomediastinum is associated with higher mortality rates, prolonged intensive care unit (ICU) stays making it a poor prognostic marker. There is no consensus regarding its management in COVID-19 patients although both aggressive and conservative strategies have been tried.

Background/aim: Silicosis, the most severe type of occupational pneumoconiosis, leads to diffuse pulmonary fibrosis without specific therapy. Ferroptosis is triggered by reactive oxygen species (ROS) and Fe overload-induced lipid peroxidation, which is involved in the progression of pulmonary fibrosis. As an important coenzyme in the process of aerobic respiration, Coenzyme Q10 (CoQ10) can enhance mitochondrial function and energy supply and reduce malondialdehyde (MDA) to limit the risk of fibrosis.

Background/aim: This study aimed to investigate the safety and efficacy of deferoxamine (DFO) pretreated feline adipose tissue derived mesenchymal stem cells (fATMSCs) for the treatment of inflammatory disorders.
Materials And Methods: fATMSCs were isolated from feline adipose tissue and characterized using flow cytometry for surface marker expression and differentiation assays for adipogenic, osteogenic, and chondrogenic lineages. Different concentrations of DFO were used to evaluate its impact on fATMSC activity.

Background/aim: Acute lung injury (ALI) is an important pathological process in acute respiratory distress syndrome; however, feasible and effective treatment strategies for ALI are limited. Recent studies have suggested that stem cell-derived exosomes can ameliorate ALI; however, there remains no consensus on the protocols used, including the route of administration. This study aimed to identify the appropriate route of administration of canine stem cell-derived exosomes (cSC-Exos) in ALI.

Mitochondrial quality control is crucial in sepsis-induced acute lung injury (SI-ALI). Our study investigates how the intracellular protein TBC1D15 regulates mitochondrial quality to improve SI-ALI. We found TBC1D15 levels significantly decreased in the whole blood of sepsis patients, monocytes, lung tissue from SI-ALI mice, and the MLE-12 cellular model (mouse lung epithelial cells).

Co-exposure to ground-level ozone (O) and fine particles (PM, ≤ 2.5 µm in diameter) has become a primary scenario for air pollution exposure of urbanites in China. Recent studies have suggested a synergistic effect of PM and O on induction of lung inflammatory injury.
