Multicenter Study
Association between insomnia and asthma burden in the Severe Asthma Research Program (SARP) III.
Sleep difficulties are commonly reported by patients with asthma; however, the prevalence of insomnia and its association with disease burden and well-being is unknown. We aimed to determine the prevalence of insomnia, defined as combined sleep-specific complaints with associated daytime symptoms, among a large sample of adults with asthma, and to compare well-being, asthma control, and asthma-related health care utilization in individuals with asthma and insomnia and those without insomnia. ⋯ Insomnia is highly prevalent in asthma and is associated with adverse outcomes. Further studies are needed to gain a better understanding of the interaction between insomnia and asthma control.

Macrolides for Clinically Significant Bronchiectasis in Adults: Who Should Receive this Treatment?
Long-term macrolide therapy offers an evidence-based treatment to reduce frequent exacerbations in stable adult patients with bronchiectasis. There is limited evidence that these agents also attenuate the decline in lung function and improve health-related quality of life. ⋯ Further work is needed to understand the optimal drug, dose, and regimen, the mechanisms behind these benefits, appropriate patient selection, sustainability of efficacy, potential long-term risk for the lung microbiome; and their use with or without inhaled antibiotic treatment. We reviewed the current evidence on long-term macrolides in adults with bronchiectasis.

The critically ill, asplenic patient presents a variety of management challenges. Historically, the focus of the care of the asplenic population has been the prevention and management of infection, including the often-fatal overwhelming postsplenectomy infection with encapsulated organisms such as Streptococcus pneumoniae. ⋯ Because of the relatively small size of this population and the relative infrequency with which critical illness occurs in it, there are few controlled trials that can serve as a basis for therapeutic maneuvers; thus, optimal management requires an astute clinician with an understanding of the pathogenetic mechanisms underlying the reported consequences of splenectomy. The purpose of this review is to explore the pathophysiology of the asplenic state-impairment in adaptive immunity, loss of blood filtration, endothelial dysfunction, and dysregulated coagulation-and how it leads to infection, thrombosis, and pulmonary hypertension as well as to discuss the implications of these conditions on the management of the critically ill, splenectomized patient.

Among the interstitial lung diseases (ILDs), idiopathic pulmonary fibrosis (IPF), chronic hypersensitivity pneumonitis, and fibrotic connective tissue disease-related ILD are associated with a worse prognosis, with death occurring as a result of both respiratory failure and serious associated comorbidities. The recent development and approval of the antifibrotic agents nintedanib and pirfenidone, both of which reduced the rate of decline in lung function in patients with IPF in clinical trials, offer hope that it may be possible to alter the increased mortality associated with IPF. ⋯ Patients with fibrotic ILD may benefit from identification and management of associated comorbid conditions such as pulmonary hypertension, gastroesophageal reflux, and OSA, which may improve the quality of life and, in some cases, survival in affected individuals. Because early assessment may optimize posttransplantation outcomes, lung transplant evaluation should occur early in patients with IPF and those with other forms of fibrotic ILD.

Endobronchial ultrasonography (EBUS) has become an invaluable tool in the diagnosis of patients with a variety of thoracic abnormalities. The majority of EBUS procedures are used to diagnose and stage mediastinal and hilar abnormalities, as well as peripheral pulmonary targets, with a probe-based technology. Nearly 1,000 articles have been written about its use and utility. ⋯ These new codes have been through the valuation process, and the new rule for reimbursement has been active since January 1, 2016 with National Correct Coding Initiative correction as of April 1, 2016. The impact of these new codes will result in a net reduction in professional and technical reimbursement. This article describes the current use of EBUS and explains the current codes and professional reimbursement.
