There are randomized controlled study data showing that endobronchial one-way valves (EBV) are useful for bronchoscopic lung volume reduction (BLVR). There is also case series data showing EBV to be effective in stopping persistent air leaks complicating pneumothoraces. We describe a 66-year-old man with severe chronic obstructive pulmonary disease (COPD) who failed assessments for BLVR because of the inability to perform the carbon monoxide diffusion test but subsequently had EBV deployed to his right upper lobe bronchi for persistent air leak complicating a spontaneous pneumothorax. Afterwards, there was subjective improvement in breathlessness, exercise capacity, and reduced frequency of exacerbations requiring hospitalization. Lung function parameters showed marked improvement. This case suggests that patients with compatible spirometric lung volume and computed tomography findings should proceed with BLVR. In addition, one should be aware of the possibility of improved lung function in patients with pulmonary emphysema following implantation of EBV for persistent air leak.

Background: Epidemiological studies have consistently demonstrated a robust association between long-term exposure to air pollutants and respiratory diseases. However, establishing causal relationships remains challenging due to residual confounding in observational studies. In this study, Mendelian randomization (MR) analysis was used to explore the causal and epigenetic relationships between various air pollutants and common respiratory diseases.

The warm Western Boundary Currents (WBCs) and their zonal extensions are persistent, deep, strong and narrow oceanic currents. They are known to anchor and energize the Extra-Tropical storm tracks by frontal thermal air-sea interactions. However, even in the latest generation of climate models, WBCs are characterized by large biases, and both the present storm-track activity and its recent intensification are poorly estimated.

The imbalance in the proportion of M1/M2 macrophage polarization is a crucial contributor to the persistent progression of osteoarthritis (OA). This study aimed to evaluate the effects of low-dose biocompatible ionized air (BIA) on macrophage polarization and its subsequent chondroprotective effects, thereby validating the potential of BIA in slowing the progression of OA. In vitro experiments demonstrated that BIA modulates the polarization of M1 macrophages toward the M2 phenotype via the ROS-mediated STAT6 pathway.

Sand and dust storms (SDS) can cause adverse health effects, with the oxidative potential (OP) and environmentally persistent free radicals (EPFRs) inducing oxidative stress. We mapped the OP and EPFRs concentrations at 1735 sites in China during SDS periods using experimental data for 2021-2023 and a random forest model. We examined 855,869 hospitalizations during SDS events for 2015-2022 in Beijing, China.
