Molecular breath profile of acute COPD exacerbations.

Acute exacerbations of chronic obstructive pulmonary disease (AECOPD) show high variability in individual susceptibility and promote disease progression; thus, accurate diagnosis and treatment is essential. Unravelling the molecular metabolic changes during AECOPD in breath could promote understanding of AECOPD and its treatment. Our objective was to investigate the metabolic breath profiles during AECOPD for biomarker detection.

Successful Bronchoscopic Lung Volume Reduction with New Lung Tensioning Device Coil: A Case Report.

Introduction: Bronchoscopic lung volume reduction (BLVR) using endobronchial coil treatment is a widely studied therapeutic option in patients with end-stage chronic obstructive pulmonary disease (COPD) and pulmonary emphysema. However, patient responses were inconsistent, and, from 2020, production discontinuation rendered the treatment unavailable. In the meantime, a next-generation lung tensioning coil (FreeFlow Coil 4; FreeFlow Medical, Inc.

Exhaled breath analysis in patients with potentially curative lung cancer undergoing surgery: a longitudinal study.

Exhaled breath analysis has emerged as a non-invasive and promising method for early detection of lung cancer, offering a novel approach for diagnosis through the identification of specific biomarkers present in a patient's breath. For this longitudinal study, 29 treatment-naive patients with lung cancer were evaluated before and after surgery. Secondary electrospray ionization high-resolution mass spectrometry was used for exhaled breath analysis.

Effects of continuous positive airway pressure therapy on glucose metabolism in patients with obstructive sleep apnoea and type 2 diabetes: a systematic review and meta-analysis.

Obstructive sleep apnoea is a highly prevalent chronic disorder and has been shown to be associated with disturbed glucose metabolism and type 2 diabetes. However, the evidence from individual clinical trials on the effect of continuous positive airway pressure (CPAP) treatment on glycaemic control in patients with co-existing obstructive sleep apnoea and type 2 diabetes remains controversial. A systematic review of randomised controlled trials assessing the effect of CPAP on glycaemic control in patients with obstructive sleep apnoea and type 2 diabetes was conducted using the databases MEDLINE, Embase, Cochrane and Scopus up to December 2022.

Chest CT Findings after Mild COVID-19 Do Not Explain Persisting Respiratory Symptoms: An Explanatory Study.

(1) Background: Lung tissue involvement is frequently observed in acute COVID-19. However, it is unclear whether CT findings at follow-up are associated with persisting respiratory symptoms after initial mild or moderate infection. (2) Methods: Chest CTs of patients with persisting respiratory symptoms referred to the post-COVID-19 outpatient clinic were reassessed for parenchymal changes, and their potential association was evaluated.

Augmentation Index in Patients with Thoracic Aortic Aneurysm: A Matched Case-Control Study.

Thoracic aortic aneurysms (TAA) may be associated with complications such as rupture and dissection, which can lead to a fatal outcome. Increased central arterial stiffness has been proposed to be present in patients with TAA compared to unmatched controls. We aimed to assess whether wall properties in patients with TAA are also altered when compared to a matched control group.

Safety and Performance of Transbronchial Cryobiopsy for Parenchymal Lung Lesions.

Background: Despite advances in technology, the bronchoscopic diagnosis of parenchymal pulmonary lesions (PPLs) remains difficult to achieve. Transbronchial lung cryobiopsy (TLCB) offers the potential for larger samples with improved diagnostic yield; however, a paucity of data exists describing its safety and usefulness for the diagnosis of PPL.

Research Question: What is the safety profile of TLCB for PPL?

Study Design And Methods: An observational, retrospective, multicenter cohort study enrolled patients without endobronchial disease undergoing TLCB of PPL from 2015 through 2019.

The Modern Art of Reading Computed Tomography Images of the Lungs: Quantitative CT.

Lung diseases are increasing in prevalence and overall burden worldwide. To stem the tide, more and more national and international guidelines are recommending the use of various diagnostic algorithms that are disease specific. There is growing consensus among the respiratory community that although patient histories and lung function testing are the minimum required for clinical examinations, these tests alone are not sufficient for disease characterization.
