Review Meta Analysis
The presence of diffuse alveolar damage on open lung biopsy is associated with mortality in patients with acute respiratory distress syndrome: a systematic review and meta-analysis.
Diffuse alveolar damage (DAD) is considered the histologic hallmark of ARDS although DAD is absent in approximately half of patients with ARDS. The clinical implications of having the syndrome of ARDS with DAD vs other histologic patterns is unknown. To address this question, we conducted a meta-analysis of lung biopsy series for patients with ARDS. ⋯ This meta-analysis demonstrated that ARDS with DAD is associated with higher mortality than ARDS without DAD.

Review
3D Printing and 3D Slicer - Powerful Tools in Understanding and Treating Structural Lung Disease.
Recent advances in the three-dimensional (3D) printing industry have enabled clinicians to explore the use of 3D printing in preprocedural planning, biomedical tissue modeling, and direct implantable device manufacturing. Despite the increased adoption of rapid prototyping and additive manufacturing techniques in the health-care field, many physicians lack the technical skill set to use this exciting and useful technology. Additionally, the growth in the 3D printing sector brings an ever-increasing number of 3D printers and printable materials. ⋯ Additionally, we will address some of the major barriers to wider adoption of the technology in the medical field. Finally, we will provide an initial guide to 3D modeling and printing by demonstrating how to design a personalized airway prosthesis via 3D Slicer. We hope this information will reduce the barriers to use and increase clinician participation in the 3D printing health-care sector.

Observational Study
Cohort study on the management of cancer-associated venous thromboembolism aimed at the safety of stopping anticoagulant therapy in patients cured from cancer.
After diagnosis of cancer-associated VTE, guidelines recommend considering the continuation of anticoagulant treatment until the patient is cured of cancer, although the safety of stopping anticoagulant treatment after the patient is cured has never been evaluated. ⋯ Our data support the recommendation to stop anticoagulant treatment of cancer-associated VTE in patients cured of cancer. A cancer relapse seems to be a strong risk factor for recurrent symptomatic VTE.

Review Meta Analysis
A systematic review with meta-analysis of dual bronchodilation with LAMA/LABA for the treatment of stable chronic obstructive pulmonary disease.
The wide availability of long-acting muscarinic antagonist (LAMA)/long-acting β2-agonist (LABA) fixed-dose combinations (FDCs) in the absence of head-to-head comparative pragmatic trials makes it difficult to choose which combination should be used. Therefore, we carried out a systematic review with meta-analysis that incorporated the data from trials lasting at least 3 months to evaluate the effectiveness of LAMA/LABA FDCs for COPD treatment. ⋯ The gradient of effectiveness emerging from this meta-analysis is merely a weak indicator of possible differences between the various LAMA/LABA FDCs. Only direct comparisons will document if a specific LAMA/LABA FDC is better than the other. In the meanwhile, we believe it is only proper to consider that dual bronchodilation is better than a LAMA or a LABA alone, regardless of the drugs used.

Case Reports
An 80-Year-Old Man With Dyspnea and Bilateral Pleural Effusions After Partial Nephrectomy for Renal Cell Carcinoma.
An 80-year-old man presented because of superficial head trauma sustained after falling from bed. On review of systems, he reported worsening dyspnea on exertion, nonproductive cough, and weight loss over the preceding 2 to 3 months. There was no report of chest pain or leg swelling. ⋯ His medications included levothyroxine, hydrochlorothiazide, and clopidogrel. He had never smoked and had done clerical work until retirement. He was originally from Colombia.
