Subcentimeter nodules without change in size during long-term follow-up period (for minimum 2 years) are assumed as benign lesions. However, the 2-year stability rule has not been fully verified so far and is still questionable. Thus, we aimed to retrospectively investigate long-term follow-up results for 2-year stable subcentimeter nodules at screening low-dose computed tomography (LDCT). ⋯ All solid subcentimeter nodules having initial 2-year stability at screening LDCT can be considered benign because none shows growth at further follow-up CT. On the other hand, subcentimeter GGNs have more chance of growth than solid nodules and need further follow-up CT for more than 2 years.

The previous use of inhaled corticosteroids (ICS) may reduce the inflammatory response and mortality in patients with community-acquired pneumonia (CAP). ⋯ Previous use of ICS in patients hospitalized for CAP is associated with a reduced systemic inflammatory response without any impact on long-term mortality.

Review Meta Analysis
Endobronchial ultrasound-guided transbronchial needle biopsy for the diagnosis of intrathoracic lymph node metastases from extrathoracic malignancies: a meta-analysis and systematic review.
Intrathoracic lymph node metastases in patients with extrathoracic malignancies are a common clinical manifestation. Several studies evaluating intrathoracic lymph node metastases in patients with extrathoracic malignancy by using the endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) have been reported. The objective of this meta-analysis is to investigate the diagnostic value of EBUS-TBNA for diagnosing intrathoracic lymph node metastases in patients with extrathoracic malignancies. ⋯ The overall DOR was 179.77 (95% CI: 66.29-487.50). The area under the SROC curve and the diagnostic accuracy were 0.9247 and 0.8588, respectively. Evidence gathered from studies of moderate quality reveals a high degree of diagnostic accuracy of EBUS-TBNA for diagnosing intrathoracic lymph node metastases in patients with extrathoracic malignancies.

The last decade has seen a significant advance in understanding about early lung disease in cystic fibrosis (CF). As studies that have measured lung function in preschool years are conducted in association with surveillance of infection, inflammation and early structural changes, and emerging longitudinal data become available, a better insight into the very early onset and nature of such lung disease is emerging. ⋯ Lung function measurement in CF is potentially an important assessment tool and is used in routine clinical practice in several centres already. Results of studies from lung function tests that, on the basis of their underpinning physiology, are viewed as being best suited currently for the early detection of lung disease in CF are reviewed.

Observational Study
Physical comorbidities affect physical activity in chronic obstructive pulmonary disease: a prospective cohort study.
The prevalence of physical comorbidities such as obesity, musculoskeletal or neurological conditions in people with chronic obstructive pulmonary disease (COPD) is high, yet little is known about the impact of these physical comorbidities on physical activity. The primary aim of the study was to compare the physical activity levels of people with COPD with physical comorbidities (COPD + PC) to people with COPD without physical comorbidities (COPD) and healthy age-matched volunteers (control group). ⋯ People with COPD + PC had significantly lower daily physical activity levels compared with people with COPD without physical comorbidities and healthy people.
