Shortened telomere length (STL) is associated with increased rates of interstitial lung diseases, malignancy, hematological disorders, and immunosuppressive treatment toxicities. In this single-center retrospective study, we aim to determine whether patients with interstitial lung diseases who have STL, as determined by quantitative PCR of buccal epithelial cells, exhibit worse post-transplant outcomes compared to recipients with normal telomere length. In our series of 26 patients, STL was associated with a higher incidence of chronic kidney disease following lung transplantation (100% vs 55%, P = .042). However, STL was not associated with an increased incidence of acute cellular rejection, infections, cytomegalovirus viremia, cytopenias, elevated liver enzymes, cancer diagnosis, venous thromboembolism, or mortality. Thus, lung transplant recipients with STL are at an increased risk of developing chronic kidney disease during the post-transplant period compared to those with normal telomere length.

A scoping review was conducted to investigate the role of radiological imaging, particularly high-resolution computed tomography (HRCT), and artificial intelligence (AI) in diagnosing and prognosticating idiopathic pulmonary fibrosis (IPF). Relevant studies from the PubMed database were selected based on predefined inclusion and exclusion criteria. Two reviewers assessed study quality and analyzed data, estimating heterogeneity and publication bias.

Objective: To examine the course of interstitial lung disease associated with rheumatoid arthritis (RA-ILD) in France on treatment with Janus kinase inhibitors (JAKis) using the MAJIK-SFR registry.
Methods: Prospective national multicentre observational study identifying patients with RA-ILD from the MAJIK-SFR registry. Pulmonary assessment data were collected at JAKi initiation and follow-up visits (6 months, 12 months and a median of 21 months postinclusion), including chest high-resolution CT (HRCT), pulmonary function tests (forced vital capacity (FVC) and diffusing capacity of the lungs for carbon monoxide (DLCO)), acute exacerbations of ILD, respiratory infections and lung cancers.

Idiopathic nonspecific interstitial pneumonia (iNSIP) is recognized as a distinct entity among various types of idiopathic interstitial pneumonias (IIP). It is identified histologically by the nonspecific interstitial pneumonia (NSIP) pattern. A diagnosis of iNSIP is feasible once secondary causes or underlying diseases are ruled out.

Objectives: The aims of the study are to predict lung function impairment in patients with connective tissue disease (CTD)-associated interstitial lung disease (ILD) through computed tomography (CT) quantitative analysis parameters based on CT deep learning model and density threshold method and to assess the severity of the disease in patients with CTD-ILD.
Methods: We retrospectively collected chest high-resolution CT images and pulmonary function test results from 105 patients with CTD-ILD between January 2021 and December 2023 (patients staged according to the gender-age-physiology [GAP] system), including 46 males and 59 females, with a median age of 64 years. Additionally, we selected 80 healthy controls (HCs) with matched sex and age, who showed no abnormalities in their chest high-resolution CT.
Purpose: Datopotamab deruxtecan (Dato-DXd) is a trophoblast cell-surface antigen-2-directed antibody-drug conjugate with a highly potent topoisomerase I inhibitor payload. The TROPION-Lung05 phase II trial (ClinicalTrials.gov identifier: NCT04484142) evaluated the safety and clinical activity of Dato-DXd in patients with advanced/metastatic non-small cell lung cancer (NSCLC) with actionable genomic alterations progressing on or after targeted therapy and platinum-based chemotherapy.
