Asthma Control According to GINA 2023: Does Changing the Criteria Improve Asthma Control?

: Achieving disease control is the main goal in asthmatic patients in order to prevent future risks and exacerbations. There are several clinical guidelines that set different definitions of asthma control, and these differences may affect management and treatment in many patients. Our aim was to describe asthma control patterns according to the Global Initiative for Asthma (GINA) 2023 in patients considered to have uncontrolled asthma as per previous GINA 2010 guidelines.

Utility of bronchoalveolar lavage for COVID-19: a perspective from the Dragon consortium.

Diagnosing COVID-19 and treating its complications remains a challenge. This review reflects the perspective of some of the Dragon (IMI 2-call 21, #101005122) research consortium collaborators on the utility of bronchoalveolar lavage (BAL) in COVID-19. BAL has been proposed as a potentially useful diagnostic tool to increase COVID-19 diagnosis sensitivity.

Relaxation differences using EIS through bronchoscopy of healthy and pathological lung tissue.

The use of electrical impedance spectroscopy for lung tissue differentiation is an opportunity for the improvement of clinical diagnosis. The aim of this work is to distinguish among different lung tissue states by evaluating the differences among impedance spectrum parameters between two separate frequencies (15 kHz and 307 kHz) in the beta dispersion region. In previous studies we have used single frequency measurements for tissue differentiation.

Differentiation using minimally-invasive bioimpedance measurements of healthy and pathological lung tissue through bronchoscopy.

Purpose: To use minimally-invasive transcatheter electrical impedance spectroscopy measurements for tissue differentiation among healthy lung tissue and pathologic lung tissue from patients with different respiratory diseases (neoplasm, fibrosis, pneumonia and emphysema) to complement the diagnosis at real time during bronchoscopic procedures.

Methods: Multi-frequency bioimpedance measurements were performed in 102 patients. The two most discriminative frequencies for impedance modulus (|Z|), phase angle (PA), resistance (R) and reactance (Xc) were selected based on the maximum mean pair-wise Euclidean distances between paired groups.

Sarcoidosis following SARS-CoV-2 infection: Cause or consequence?

The COVID-19 pandemic has been a worldwide medical challenge. Despite rapid advancements, many questions regarding SARS-CoV-2 interaction with other pathologies and long-term consequences remained unanswered. Sarcoidosis is a multi-systemic granulomatous disease that develops in genetically predisposed individuals following their exposure to an environmental trigger.

Bronchial Thermoplasty Global Registry (BTGR): 2-year results.

Objectives: Bronchial thermoplasty (BT) is a device-based treatment for subjects ≥18 years with severe asthma not well controlled with inhaled corticosteroids and long-acting beta-agonists. The Bronchial Thermoplasty Global Registry (BTGR) collected real-world data on subjects undergoing this procedure.

Design: The BTGR is an all-comer, prospective, open-label, multicentre study enrolling adult subjects indicated for and treated with BT.

Bronchoalveolar Lavage Complements Transbronchial Cryobiopsy Diagnosis in Diffuse Interstitial Lung Diseases.

Background: Bronchoalveolar lavage (BAL) is a technique classically used for the study of diffuse interstitial lung diseases (DILDs). Given the recent advances in the diagnosis of DILD by transbronchial cryobiopsy (TBCB), it is relevant to assess what BAL can contribute to TBCB.

Patients And Methods: This is a retrospective descriptive study that included patients with DILD who, between 2013 and 2017, underwent BAL and TBCB in the same bronchoscopy intervention.

Diagnosis and invasive staging: Non-surgical invasive mediastinal staging. Endobronchial ultrasound.

Unlabelled: The diagnosis and staging of lung cancer are an important process that identifies treatment options and guides disease prognosis. Therefore, an accurate mediastinal lymph node (LN) staging is required not only to offer the appropriate treatment but also to avoid unnecessary invasive procedures. At present, endobronchial ultrasound (EBUS)-transbronchial needle aspiration is the preferred modality for sampling mediastinal lymph nodes because of its minimally invasive nature and high diagnostic yield.

Bronchoscopist's perception of the quality of the single-use bronchoscope (Ambu aScope4™) in selected bronchoscopies: a multicenter study in 21 Spanish pulmonology services.

Background: The disposable bronchoscope is an excellent alternative to face the problem of SARS-CoV-2 and other cross infections, but the bronchoscopist's perception of its quality has not been evaluated.

Methods: To evaluate the quality of the Ambu-aScope4 disposable bronchoscope, we carried out a cross-sectional study in 21 Spanish pulmonology services. We use a standardized questionnaire completed by the bronchoscopists at the end of each bronchoscopy.

Minimally Invasive Real-Time Electrical Impedance Spectroscopy Diagnostic Tool for Lung Parenchyma Pathologies.

Electrical Impedance Spectroscopy has already demonstrated the ability to distinguish different tissues types, or tumors from normal tissue, or tissues displaying diverse degrees of pathology. When applying the technique, however, the necessity to make contact with the tissue often constitutes a practical limitation. Electrical Impedance Imaging (EIT), or in a broader sense, regional impedance assessment, struggle to assess different tissue conditions out of measurements from the surface of the body.

Transbronchial biopsy results according to diffuse interstitial lung disease classification. Cryobiopsy versus forceps: MULTICRIO study.

Background: In recent years, transbronchial cryobiopsy (TBCB) has come to be increasingly used in interventional pulmonology units as it obtains larger and better-quality samples than conventional transbronchial lung biopsy (TBLB) with forceps. No multicenter studies have been performed, however, that analyse and compare TBCB and TBLB safety and yield according to the interstitial lung disease (ILD) classification.

Objectives: We compared the diagnostic yield and safety of TBCB with cryoprobe sampling versus conventional TBLB forceps sampling in the same patient.

Transbronchial cryobiopsy increases diagnostic confidence in interstitial lung disease: a prospective multicentre trial.

Introduction: The accurate diagnosis of individual interstitial lung diseases (ILD) is often challenging, but is a critical determinant of appropriate management. If a diagnosis cannot be made after multidisciplinary team discussion (MDTD), surgical lung biopsy is the current recommended tissue sampling technique according to the most recent guidelines. Transbronchial lung cryobiopsy (TBLC) has been proposed as an alternative to surgical lung biopsy.

Performing Bronchoscopy in Times of the COVID-19 Pandemic: Practice Statement from an International Expert Panel.

These recommendations for physicians who perform bronchoscopy will help to protect those patients (un)-affected by the current COVID-19 pandemic, minimize the risk of transmission, and maintain clinical care for all patients.

A Multidisciplinary Proposal for a Diagnostic Algorithm in Idiopathic Pulmonary Fibrosis: The Role of Transbronchial Cryobiopsy.

The diagnosis of idiopathic pulmonary fibrosis (IPF) is a complex process that requires the multidisciplinary integration of clinical, radiological, and histological variables. Due to its diagnostic yield, surgical lung biopsy has been the recommended procedure for obtaining samples of lung parenchyma, when required. However, given the morbidity and mortality of this technique, alternative techniques which carry a lower risk have been explored.

Mixed Th2 and non-Th2 inflammatory pattern in the asthma-COPD overlap: a network approach.

Introduction: The asthma-chronic obstructive pulmonary disease (COPD) overlap (ACO) is a clinical condition that combines features of those two diseases, and that is difficult to define due to the lack of understanding of the underlying mechanisms. Determining systemic mediators may help clarify the nature of inflammation in patients with ACO.

Objectives: We aimed at investigating the role and interaction of common markers of systemic inflammation (IL-6, IL-8, and tumor necrosis factor-α), Th2-related markers (periostin, IL-5, and IL-13), and IL-17 in asthma, COPD, and ACO.
