The Clinical Utility of Pulmonary Function Tests in the Diagnosis and Characterization of Central Airway Obstruction: A Narrative Review.

Central airway obstruction is of major clinical importance since it is a major cause of morbidity and mortality and is usually clinically diagnosed late. Pulmonary function tests, with the recent incorporation of oscillometry, can have a crucial role in earlier diagnosis. In this review, we summarize all recent advances in that view, including the crucial role of oscillometry.

Interstitial Lung Diseases and Non-Small Cell Lung Cancer: Particularities in Pathogenesis and Expression of Driver Mutations.

Introduction: Interstitial lung diseases are a varied group of diseases associated with chronic inflammation and fibrosis. With the emerging and current treatment options, survival rates have vastly improved. Having in mind that the most common type is idiopathic pulmonary fibrosis and that a significant proportion of these patients will develop lung cancer as the disease progresses, prompt diagnosis and personalized treatment of these patients are fundamental.

Expression of Pluripotency Factors OCT4 and LIN28 Correlates with Survival Outcome in Lung Adenocarcinoma.

Lung adenocarcinoma is a leading cause of cancer-related mortality despite recent therapeutic advances. Cancer stem cells have gained increasing attention due to their ability to induce cancer cell proliferation through self-renewal and differentiation into multiple cell lineages. OCT4 and LIN28 (and their homologs A and B) have been identified as key regulators of pluripotency in mammalian embryonic (ES) and induced stem (IS) cells, and they are the crucial regulators of cancer progression.

Bronchoscopy-related outbreaks and pseudo-outbreaks: A systematic review.

Objective: To identify and report the pathogens and sources of contamination associated with bronchoscopy-related outbreaks and pseudo-outbreaks.

Design: Systematic review.

Setting: Inpatient and outpatient outbreaks and pseudo-outbreaks after bronchoscopy.

Expression of PD-1/PD-L1 axis in mediastinal lymph nodes and lung tissue of human and experimental lung fibrosis indicates a potential therapeutic target for idiopathic pulmonary fibrosis.

Background: Mediastinal lymph node enlargement is prevalent in patients with idiopathic pulmonary fibrosis (IPF). Studies investigating whether this phenomenon reflects specific immunologic activation are lacking.

Methods: Programmed cell death-1 (PD-1)/ programmed cell death ligand-1 (PD-L1) expression in mediastinal lymph nodes and lung tissues was analyzed.

A comprehensive analysis of GATA3 expression in carcinomas of various origins with emphasis on lung carcinomas.

GATA3 is a transcription factor involved in the embryogenesis of multiple human tissues and organs and in maintaining cell differentiation and tissue homeostasis in the adult organism. GATA3 is also involved in carcinogenesis and is regarded as a sensitive marker for urothelial and breast carcinomas, although its expression in carcinomas of non-breast/urothelial origin has been frequently reported. In this study, we sought to examine the extent and intensity of GATA3 expression in various carcinomas, mainly lung, urothelial, breast, and various other primary sites.

Management of patients with idiopathic pulmonary fibrosis and lung cancer: challenges in clinical practice.

Purpose Of Review: Idiopathic pulmonary fibrosis (IPF) is the nonmalignant, chronic lung disease with the worst prognosis. Prevalent comorbidities including lung cancer exert a negative impact on patients' survival. However, there is considerable lack of knowledge on the diagnostic and therapeutic management of patients diagnosed with both clinical entities.

Post-COVID-19 interstitial lung disease: Insights from a machine learning radiographic model.

Introduction: Post-acute sequelae of COVID-19 seem to be an emerging global crisis. Machine learning radiographic models have great potential for meticulous evaluation of post-COVID-19 interstitial lung disease (ILD).

Methods: In this multicenter, retrospective study, we included consecutive patients that had been evaluated 3 months following severe acute respiratory syndrome coronavirus 2 infection between 01/02/2021 and 12/5/2022.

Clinical features and outcomes of patients with myositis associated-interstitial lung disease.

Introduction: Myositis associated interstitial lung disease (ILD) seems to be an under-recognized entity.

Methods: In this multicenter, retrospective study, we recorded between 9/12/2019 and 30/9/2021 consecutive patients who presented in five different ILD centers from two European countries (Greece, France) and received a multidisciplinary diagnosis of myositis associated-ILD. The primary outcome was all-cause mortality over 1 year in specific subgroups of patients.

Tocilizumab versus baricitinib in hospitalized patients with severe COVID-19: an open label, randomized controlled trial.

Objective: Randomized controlled trials comparing tocilizumab and baricitinib in patients with coronavirus disease 2019 (COVID-19) are needed. This was an open-label, randomized controlled trial aiming to address this unmet need.

Methods: To determine whether baricitinib was non-inferior to tocilizumab, we assessed whether the upper boundary of the two-sided 95% CI of the hazard ratio (HR) did not exceed 1.

Pulmonary adverse events following immune checkpoint inhibitors.

Purpose Of Review: Immune checkpoint inhibitors (ICIs) have rapidly become a mainstay of cancer treatment. However, immune modulation resulting from checkpoint inhibition can cause inflammation in any organ system, with pneumonitis being one of the most severe immune-related adverse events (irAEs). Here, we review the most recent literature on pulmonary adverse events following ICIs.

Fanconi syndrome-associated interstitial lung disease.

A middle-aged man was referred to our respiratory department with dyspnoea progressively deteriorating and non-productive cough over the past 8 months. High-resolution CT revealed multiple bilateral consolidations, traction bronchiectasis, reticular pattern and honeycombing with basal and peripheral predominance. Serology tests were negative.
