Multicenter Study Observational Study
Venous Thromboembolism Risk Profiles and Prophylaxis in Medical and Surgical Inpatients: The Identification of Chinese Hospitalized Patients' Risk Profile for Venous Thromboembolism (DissolVE-2) - a cross-sectional study.
Limited data exist on VTE risk and prophylaxis in Chinese inpatients. The Identification of Chinese Hospitalized Patients' Risk Profile for Venous Thromboembolism-2 (DissolVE-2), a nationwide, multicenter, cross-sectional study, was therefore designed to investigate prevalence of VTE risks and evaluate VTE prophylaxis implementation compliant with the latest prophylaxis guidelines (American College of Chest Physicians [CHEST], 9th edition). ⋯ A large proportion of hospitalized patients reported VTE risk and low rate of CHEST-recommended prophylaxis. The data highlight the insufficient management of VTE risk and show the great potential for improving physicians' awareness and current practices across China.

Cystic fibrosis (CF) is a multiorgan, genetic disease resulting from dysfunction of the CF transmembrane conductance regulator. The primary clinical manifestations are bronchiectasis, chronic pulmonary infections with recurrent exacerbations, and pancreatic insufficiency. Advances in CF care have led to improved survival, with more than one-half of those affected being adults. ⋯ Multiple aspects of the care of patients with CF benefit from specialized knowledge, including pancreatic enzyme replacement and nutritional support; airway clearance modalities; treatment of multiply resistant, polymicrobial infections, and unique drug metabolism. In extreme cases, patients may benefit from advanced therapies, including extracorporeal support and organ transplant. Optimal care of patients with CF requires a multidisciplinary care team that includes respiratory therapists, dieticians, social workers, psychologists, pharmacists, and physicians who have expertise in the treatment of this complex, multisystem disorder.

Effectiveness of Influenza Vaccination on Hospitalizations and Risk Factors for Severe Outcomes in Hospitalized Patients With COPD.
The effectiveness of influenza vaccination in reducing influenza-related hospitalizations among patients with COPD is not well described, and influenza vaccination uptake remains suboptimal. ⋯ Influenza vaccination significantly reduced influenza-related hospitalization among patients with COPD. Initiatives to increase vaccination uptake and early use of antiviral agents among patients with COPD could reduce influenza-related hospitalization and critical illness and improve health-care costs in this vulnerable population.

Randomized Controlled Trial Multicenter Study
Surgical Disparities Among Patients With Stage I Lung Cancer in the National Lung Screening Trial.
Low-dose CT scan reduces lung cancer mortality in high-risk patients fit to undergo surgical resection. Racial disparities in resection of lung cancer in nonscreening populations are well described. We describe surgical resection patterns of patients with early stage non-small cell lung cancer (NSCLC) in the National Lung Screening Trial (NLST) and examine whether racial disparities exist among blacks. ⋯ Our study shows that disparities in the surgical treatment of lung cancer persist, even among NLST participants who were considered fit to undergo thoracic surgery. As lung cancer screening disseminates into clinical practice, efforts targeting black men should be prioritized.

Observational Study
CT-Based Low-Attenuation Super Clusters in 3D and the Progression of Emphysema.
Distributions of low-attenuation areas in two-dimensional (2-D) CT lung slices are used to quantify parenchymal destruction in patients with COPD. However, these segmental approaches are limited and may not reflect the true three-dimensional (3-D) tissue processes that drive emphysematous changes in the lung. The goal of this study was to instead evaluate distributions of 3-D low-attenuation volumes, which we hypothesized would follow a power law distribution and provide a more complete assessment of the mechanisms underlying disease progression. ⋯ Low-attenuation super clusters are defining, quantitative features of parenchymal destruction that dominate disease progression, particularly in advanced COPD.
