Anti-melanoma differentiation-associated gene 5-positive dermatomyositis-associated interstitial lung disease (MDA5+DM-ILD) often leads to acute respiratory failure and endangers lives. This study quantitatively analysed chest high-resolution computed tomography (HRCT) images to assess MDA5+DM-ILD and establish a risk prediction model for severe ILD within six months. ⋯ The STRAD-Ro52 model assists in identifying MDA5+DM patients at risk of developing severe ILD within six months, further optimizing precise disease management and clinical research design.

Serial Pulmonary Hemodynamics in Patients with IPF Listed for Lung Transplant.
Pulmonary hypertension (PH) commonly complicates idiopathic pulmonary fibrosis (IPF). However, the rate of change in pulmonary hemodynamics in IPF remains poorly defined. ⋯ PH associated with IPF tends to progress in an unpredictable fashion, with some patients demonstrating an accelerated phenotype. Among patients with RHC hemodynamics below the threshold for therapy, close vigilance is warranted with consideration for an early repeat RHC.

With the increasing utilization of cancer therapy, the incidence of lung injury associated with these treatments continues to rise. The recognition of pulmonary toxicity related to cancer therapy has become increasingly critical, for which interstitial lung disease (ILD) is a common cause of mortality. ⋯ This review aims to provide valuable information on the risk factors associated with CT-ILD; elucidate its underlying mechanisms; discuss its clinical features, imaging, and histological manifestations; and emphasize the clinical-related views of its diagnosis. In addition, this review provides an overview of grading, typing, and staging treatment strategies used for the management of CT-ILD.

Aims/Background Epidemiological studies indicate that the involvement of the immune system in the pathogenesis of infections associated with chronic obstructive pulmonary disease (COPD), asthma, and interstitial lung disease (ILD) remains unclear. This study aims to assess the potential causal link between infections associated with COPD, asthma, or ILD and immune system function. Methods We conducted a two-sample Mendelian randomization analysis using publicly available genome-wide association study (GWAS) datasets. ⋯ The causal effect of COPD/asthma/ILD-related infections on Immunoglobulin D (IgD) expression in IgD+ CD38br and transitional B cells was estimated to be 0.64 (95% CI: 0.49-0.83, p = 0.00091) and 0.70 (95% CI: 0.54-0.91, p = 0.00727), respectively. Additionally, COPD/asthma/ILD-related infections demonstrated a significant causal effect on several B cell and T cell subpopulations: IgD+ CD38- % B cells, IgD+ CD38- AC, CD4+ CD8dim AC, IgD+ CD38- % lymphocyte, and TD CD4+ AC, with the OR 1.54 (95% CI: 1.19-2.00, p = 0.00113), 1.56 (95% CI: 1.16-2.10, p = 0.00340), 1.60 (95% CI: 1.15-2.22, p = 0.00478), 1.47 (95% CI: 1.12-1.92, p = 0.00483) and 1.63 (95% CI: 1.14-2.34, p = 0.00725), respectively. Conclusion Our study reveals a causal association between altered circulating blood cell counts and specific immunophenotypes with the susceptibility to respiratory infections related to COPD, asthma, and ILD.

Pulmonary rehabilitation (PR) is a beneficial intervention for people with interstitial lung disease (ILD), however the effect of PR on survival is unclear. This study compared the survival outcomes in people with ILD who were allocated to PR versus those who were allocated to control in two published randomised controlled trials (RCTs). ⋯ Participation in PR among people with ILD may impact survival at 5 years. Along with clinical improvements following PR, the potential for a survival benefit further strengthens the importance of PR in the standard care of people with ILD.
