Article Synopsis
  • The study investigates the link between air pollution and acute exacerbations (AEs) of COPD in China, noting that previous research largely used aggregated data, limiting insights into vulnerable populations.
  • Researchers utilized individual data from the ACURE registry and air pollution measurements based on residential addresses, employing a case-crossover design to analyze the effects of specific pollutants on AEs.
  • Results showed that increased fine and inhalable particulate matter were linked to higher risks of AEs, especially in younger individuals and those with a history of severe exacerbations, while other pollutants had less consistent associations.

Background: There is a lack of individualised prediction models for patients hospitalised with chronic obstructive pulmonary disease (COPD) for clinical practice. We developed and validated prediction models of severe exacerbations and readmissions in patients hospitalised for COPD exacerbation (SERCO).

Methods: Data were obtained from the Acute Exacerbations of Chronic Obstructive Pulmonary Disease Inpatient Registry study (NCT02657525) in China.

Background: Despite being a prognostic predictor, cardiac autonomic dysfunction (AD) has not been well investigated in chronic obstructive pulmonary disease (COPD). We aimed to characterise computed tomography (CT), spirometry, and cardiopulmonary exercise test (CPET) features of COPD patients with cardiac AD and the association of AD with CT-derived vascular and CPET-derived ventilatory efficiency metrics.

Methods: This observational cohort study included stable, non-severe COPD patients.

Despite considerable evidence for the benefit in chronic obstructive pulmonary disease (COPD), the implementation of pulmonary rehabilitation (PR) is insufficient. However, music therapy may help address this gap due to its unique benefits. Therefore, we aimed to develop a music-therapy facilitated pulmonary telerehabilitation program based on rhythm-guided walking, singing, and objective telemonitoring.

Background: Influenza and pneumococcal vaccination are a priority in patients with chronic obstructive pulmonary disease (COPD). However, limited information is available on vaccination coverage among patients with acute exacerbations of COPD (AECOPD) in China. This study aimed to determine the rates and associated factors of influenza and pneumococcal vaccination in patients hospitalized with AECOPD.

Objectives: Nerve growth factor (NGF) induces neuron transdifferentiation of adrenal medulla chromaffin cells (AMCCs) and consequently downregulates the secretion of epinephrine (EPI), which may be involved in the pathogenesis of bronchial asthma. Mammalian achaete scute-homologous 1 (MASH1), a key regulator of neurogenesis in the nervous system, has been proved to be elevated in AMCCs with neuron transdifferentiation in vivo. This study aims to explore the role of MASH1 in the process of neuron transdifferentiation of AMCCs and the mechanisms.

Article Synopsis
  • The study aimed to investigate and compare the clinical features and outcomes of patients with pre-Chronic Obstructive Pulmonary Disease (pre-COPD) versus those with confirmed COPD, specifically during hospitalizations for acute exacerbations (AECOPD).* -
  • Conducted as a multicenter observational cohort study in China, the research involved 5896 patients admitted for AECOPD between 2017 and 2021, assessing outcomes like mortality rates and readmissions based on lung function tests.* -
  • The results showed no significant differences in overall mortality or readmission rates between the pre-COPD and COPD groups, indicating similar short-term and long-term health outcomes regardless of the severity of lung function.*

Lung cancer is the most common cancer and one of the main causes of cancer-related deaths, presenting in most cases as metastatic disease. Given the frequent gene mutation and/or signaling deregulation in lung adenocarcinoma, identifying novel factors or agents that target these signaling pathways may be promising strategies for lung adenocarcinoma therapy. Herein, we identified inhibitor of DNA binding 2 (ID2) as an aberrantly downregulated gene in lung adenocarcinoma.

Objective: Stage III non-small cell lung cancer (NSCLC) is a heterogeneous group of diseases. For this subset of patients, clinical management is still under debate and prognosis remains poor so far. In the present study, we aimed to evaluate the feasibility and safety of robotic-assisted thoracic surgery after neoadjuvant chemoimmunotherapy in stage III NSCLC.

Purpose: Miliary pulmonary tuberculosis (TB) among pregnant women after fertilization embryo transfer (IVF-ET) causes poor outcomes but is rarely reported. This study analyzed the clinical characteristics and risk factors of these patients to provide hints for further studies.

Method: The demographic characteristics, clinical manifestations, radiologic features, treatment, and outcomes of six patients diagnosed from May 2012 to August 2021 in Xiangya Hospital and 69 patients that were reported in English or Chinese literature from January 1980 to August 2021 were retrospectively analyzed.

Asthma is a complex pulmonary inflammatory disease which is common among older adults. Aging-related alterations have also been found in structural cells and immune cells of asthma patients. Nonetheless, the underlying mechanism by which differenced aging-related gene contributes to asthma pathology remains unclear.

Severe RSV infection is the main cause of hospitalization to children under the age of five. The regulation of miRNAs on the severity of RSV infection is unclear. The aim of the study was to identify the critical differential expression miRNAs (DE miRNAs) that can regulate the pathological response in RSV-infected airway epithelial cells.

Asthma is a complex airway inflammatory disease that can be roughly classified into eosinophilic phenotype and non-eosinophilic phenotype. Most of the latter manifested as airway inflammation dominated by neutrophil infiltration, namely neutrophil-dominated asthma (NA). Neutrophil extracellular trapping (NETs) is a newly discovered antimicrobial mechanism of neutrophils; however, NETs can not only resist killing pathogenic microorganisms, but also promote tissue damage and autoimmune response.

Background: Chronic obstructive pulmonary disease (COPD) is a chronic lung inflammatory disease which has a close relationship with aging. Genome-wide analysis reveals that DNA methylation markers vary obviously with age. DNA methylation variations in peripheral blood have the potential to be biomarkers for COPD.

Background: Several clinical studies have evaluated the use of tralokinumab (CAT-354) administration in patients with moderate to severe asthma; no consensus on tralokinumab efficacy and safety was reached. Thus, further analysis is required on the efficacy and safety of tralokinumab as an asthma biologic.

Objective: To assess the efficacy and safety of subcutaneous injection of tralokinumab in patients with moderate to severe asthma.

Background: Previous studies have demonstrated that glucocorticoid-induced transcript 1 gene ( rs37973 mutant genotype is associated with poor inhaled corticosteroid (ICS) response in asthmatics. As human airway relaxation is regulated by circulation epinephrine, which can be enhanced by corticosteroid. It is unknown whether or not rs37973 is associated with circulation epinephrine and cortisol concentrations in asthma.

Introduction: A significant bronchodilator response is commonly defined as a 12% or greater and 200 ml or greater change in FEV from baseline according to the 2005 American Thoracic Society (ATS)/European Respiratory Society (ERS) criterion. A number of studies have shown that the ATS/ERS criterion has limitations in asthma diagnosis, and some experts have argued for correcting the criteria. The aim of this study is to investigate the diagnostic value of acute bronchodilator response for asthma in a Southern Chinese population.

Background: Notch1 has been linked to the pathogenesis of asthma due to its contribution on Th1/Th2 imbalance. γ-Secretase inhibitor (GSI) acts as an effective blocker of Notch1 signaling. Glucocorticoids (GCs) are the most effective anti-inflammatory drugs for asthma.
