Background: Fungal sensitization is a risk factor for severe asthma. Colonization in the lower respiratory tract is one of the forms of fungal exposure, and it is related to fungal sensitization. Pulmonary emphysema was recently reported to be an underlying disease of fungal colonization. The aim of study was to evaluate the prevalence of pulmonary emphysema in asthmatic patients with and without fungal sensitization.
Methods: We enrolled 108 patients with allergic asthma and divided them into the patients sensitized to Aspergillus and/or Candida (n=56) and those not sensitized to both Aspergillus and Candida (n=52). The presence of pulmonary emphysema on chest CT was evaluated retrospectively.
Results: The frequency of pulmonary emphysema was significantly higher in the patients sensitized to Aspergillus and/or Candida compared to the patients not sensitized to both fungi (P=0.0040). The frequency of pulmonary emphysema was also significantly higher in the patients sensitized to either Aspergillus or Candida compared to the patient not sensitized to the fungi (P=0.0398 and P=0.0198, respectively). A multivariate logistic regression analysis demonstrated that the presence of pulmonary emphysema was independently associated with the sensitization to Aspergillus and/or Candida (OR 7.84, 95% CI: 1.20-51.10).
Conclusions: Pulmonary emphysema is associated with sensitization to Aspergillus and/or Candida.

Background: Patients with combined pulmonary fibrosis and emphysema (CPFE) may experience emphysema or fibrosis progression on chest computed tomography (CT). This study aimed to investigate the relationship and prognosis in CPFE patients with emphysema or fibrosis progression.
Methods: A total of 188 CPFE patients were included in our retrospective cohort study.
GOLD grade-specific characterization of COPD in the COSYCONET multi-center trial: comparison of semiquantitative MRI and quantitative CT.

Department of Diagnostic and Interventional Radiology, University Hospital of Heidelberg, Heidelberg, Germany.
Objectives: We hypothesized that semiquantitative visual scoring of lung MRI is suitable for GOLD-grade specific characterization of parenchymal and airway disease in COPD and that MRI scores correlate with quantitative CT (QCT) and pulmonary function test (PFT) parameters.
Methods: Five hundred ninety-eight subjects from the COSYCONET study (median age = 67 (60-72)) at risk for COPD or with GOLD1-4 underwent PFT, same-day paired inspiratory/expiratory CT, and structural and contrast-enhanced MRI. QCT assessed total lung volume (TLV), emphysema, and air trapping by parametric response mapping (PRM, PRM) and airway disease by wall percentage (WP).

Objectives: Previous studies suggest peripheral blood immune cells associate with the progression and prognosis of lung cancer. The main purpose of this study was to explore the association of peripheral immune cell and its dynamics with the growth of pulmonary nodules.
Materials And Method: Of 9280 subjects whom had blood cell counts and chest CT scan in health check-up, 1068 participants were enrolled with the incidental pulmonary nodules of above 5mm in diameter and subsequently followed up for 2 years.

Objective: To assess the co-occurrence of incidental CT lung findings (emphysema, bronchiectasis, and airway wall thickening) as well as associated risk factors in low-dose CT (LDCT) lung cancer screening in a Chinese urban population.
Methods: Data from 978 participants aged 40-74 years from the Chinese NELCIN-B3 urban population study who underwent LDCT screening were selected. CT scans were reviewed for incidental lung findings: emphysema, bronchiectasis and airway wall thickness.
